 Q.:- What is the process of Group Discussion?

Ans.:- 

Process:-

Group discussion is a systematic and purposeful oral process. It is characterized by structured exchange of views on a particular topic, issue, problem, or situation in a formal setting. It is conducted in a systematic way. It consists of three parts:
  • Initiation
  • Body
  • Summarization

(a) Initiation-

It is the first stage of a GD. The group is given a topic to discuss. They are mediated by someone who announces the topic, allotted time, general guidelines and procedures governing the GD. The mediator withdraws to background, leaving the group free to carry on discussion without external interference. As there is no elected or designated leader of the group, one of the participants starts the discussion. S/he tells her/his views on the topic
and takes on the discussion further. Then other participants take on the discussion.

(b) Body-

This is the second stage as well as main part of a group discussion. Every participant gets involved in the discussion and presents her/his views without disturbing others. The participants either further the views of other participant(s), or disagree with the view(s).

(c) Summarization-

Most group discussions do not reach at final conclusion. It rarely happens when all the group members reach onto a consensus. But every GD is summarized. One of the
participants summarizes what the group members have discussed in a nutshell. The GD comes to an end with the summarization.

 Q.:- What are the requirements for group discussion?

Ans.:-

 Essential Requirements:-


Group discussion is an effective technique for evaluation of candidates' personality traits to select for a job or admission to professional courses. The candidate needs to acquire certain skills to prove her/him. S/he must possess:

(a) All-round Knowledge: GD is based on participants' knowledge. It is necessary for a participant to be aware of current affairs, burning sOCial, economic, political and environmental issues, scientific advancements, and lot more. In case the topic is not announced in advance, s/he must have perfect knowledge about the issues related to the topic.

(b) Analytical Thinking: The participant should have analytical bent of mind and rational thinking. S/he should analyze the situation, problem, condition, and topic. S/he should listen to each participant carefully in order to analyze his/her views.

(c) Systematic Approach: The participant should adopt systematic, scientific, and realistic approach. S/he should be impartial, rational, and factual. S/he should view the situation objectively, and utilize concrete and foolproof illustrations. The ideas and arguments should be backed by relevant facts and figures.

(d) Leadership Qualities: The participant should possess leadership qualities. There is no named leader of the group, but a good leader takes self-initiative and establishes her/him as a leader. S/he must initiate the proceeding of discussion, try to keep the discussion on a right track, promote positive atmosphere, clarify points when required, and lead the discussion to a successful conclusion.

(e) Team-management Skill: The participant needs to possess team management skill to be successful in a GD. Employers look for the candidate who can work in a team -oriented environment. The examiner(s) assesses whether the participant is a team player who can get along with people, or an individualist who is always fighting to save his/her ego. Team management skill includes positive attitude, adaptability, cooperation and coordination.

(f) Self-confidence: The participant should be self-confident. S/he should talk with confidence and self-assurance. S/he should be bold and assertive without being offensive, aggressive and rigid. Her/his body movements should reflect confidence which may not only impress the examiner(s), but also help to lead the group. S/he should avoid being boastful and pretend that s/he knows everything. S/he should keep in mind that overconfidence causes failure whereas under-confidence leads to lack of productivity.

(g) Patience: The participant should never lose her/his patience. S/he should not show aggression. S/he should listen to other participants' views, and present her/his views forcefully. S/he should not jump the gun, rather wait for right time to present the views.

(h) Appropriate Language: The participant should use appropriate language which can make the meaning clear. The points should be clear and easily understandable to the audience. S/he should avoid indirect expressions, exaggeration, artificial eloquence, and ornamentation in speech. S/he should use direct, clear and specific language to present the views.

(i) Oral Communication Skill: Group discussion is an oral activity. The participant needs to be proficient in speaking. Ability to speak confidently and convincingly is one of the prerequisites of success in group discussion. The observer(s) closely evaluates the oral communication skill of the candidates. S/he generally assesses clarity of expression, pronunciation, intonation, and effective non-verbal communication skills of the candidates.

(j) Non-verbal Skills: Body movements make oral communication more effective. The participant should use non-verbal cues, such as eye contact, gestures, facial expressions, and so on. Proper eye contact reflects confidence; shirking of eye communicates nervousness, frustration, weakness, and insecurity. S/he should also use proper hand movements wherever required.

 Q.:- What is Cell?

Ans.:-

  • Introduction
  • Structure of Cell
  • Function of a Cell
  • Mitosis
  • Meiosis
  • Determination of sex

INTRODUCTION:-

The cell is the smallest unit of living tissues. Cell of different tissues perform different functions. A cell is made up of the following structure:

(1.) Cell wall: it is the external boundary of the living cell. It is a three layered structure made up of lipids and proteins. It measures approximately  70 A% in thicknesses the cell wall allows the diffusion of substances in to and out of cell. 

(2.) Nucleus: IT is the largest structure present almost in the centre of a cell. It is more or less spherical in shape. It is bounded by nuclear membrane. The nucleus contains: 

(a) Nucleus  (b) Chromatin 

a) Nucleolus: It is a highly coiled filamentous structure present in the nucleus. It not surrounded by a memberane. But it contains numerous granules. Nucleolus is the site of ribosomal RNA (ribonucleic acid ) synthesis. 

b) Chromatin: These are fibrous threads present in the nucleus. They are composed of DNA ( deoxy ribonucleric acid ) and proteins. The Chromatin threads carry genetic information. At the time of cell division, Chromatin condensed in to Chromosomes. The number of Chromosomes is constant for a particular spcies of organisms. In man there are 23 pairs of  46 Chromosomes. 

(3.) Cytoplasm:-

It is region lying between the cell membrane and nucleus. The cytoplasm contains cell organelles like endoplasmic reticulum, golgi apparatus, mitochondria, lysosomes and centrosome.

 (4.) Microsomes: They are extremely small bodies present in the cytoplasm. They can be separated by centrifuging a tissue homogenste at Very high speed ( 10000 rpm ) microsomes contains 1 ) Ribosomes 2 ) Granuler Matrix Ribosomes are concerned with proteins synthesis. Granular Matrix contains: 

  • Oxidases which generate hydrogen peroxide.
  • Catalase which converts hydrogen peroxide in to water.

Organelles of cytoplasm: Following are the important organelles present in the cytoplasm:

i) Endoplasmic reticulum: It is the most expensive cell organelle present in cytoplasm. It consists of two membernes which are separated by a space. Endoplasmic reticulum is of two types. They are:

a) Granular: or rough surfaced endoplasmic reticulum bcontaining ribosomes. The ribosomes are the sites of proteins synthesis,

b) Agranular: or smooth surfaced endoplasmic reticulum. This does not contain ribosomes. This type of endoplasmic reticulum is concerned with fatty acid steroid synthesis. Also, they store and release calcium. 

ii) Golgi apparatus: It is a cup shaped structure and contains vesicles. It is situated between the nucleus and the apex of the cell. It is concerned with concentration of proteins prior to secretion. 

iii) Mitochondria: They occur in the cytoplasm at variable numbers e.g. few hundreds to few thousand membranes. They are:

1. An outer layer which is smooth.

2. An inner layer folded in to sheets of tubules called cristae. 

Both these layer enclose a central cavity called Matrix.

The mitochondria are made up of proteins, phospholipid and some ribonucleic acid. They also contain some important enzyme system. The mitochondria are chiefly concerned with cellular oxidation. 

iv) Lysosomes: They are small spherical or oval bodies surrounded by a single memberane . They very in numbers and contain a variety of hydrolytic enzymes . The lysosomes breakdown bacteria and cell debris engulfed by the cell. The damaged intracellular organelle are also broken down and digested by lysosomes.

v) Centrosome: it is a small rod shaped body found near the nucleus. It plays an important role during cell division. The centrosome is surrounded by a radiating threads like structure. It contains two centrioles. 

vi) Microtubules: They are straight, hollow cylinders with a diameter of about 200 A% they are concerned with the maintenance of cell shape. They also associated with movements of cilia flagella and mitotic spindles. 

 Functions of a cell:-

They following are the important functions performed by a cell.

1.) Ingestion and assimilation: The cell ingests chemical substances like amino- acid from intercellular or interstial fluid. These substances are used to build up complicated substances like proteins.

2.) Growth and repair: The ingested and assimilated materials are used to synthesis new protoplasm. This leads to increase in size and growth of the cell. Also worn out parts of the cell are replaced by this process. 

3.) Metabolism: This involves two processes: 

i) Anabolism in which the ingested and assimilated food materials is used for growth and repair. 

ii) Catabolism in which food materials is broken down to release anegry for various functions of the cell.

4.) Respiratory: It involves transport of oxygen from lung through blood to the tissues and removal of waste products like carbondioxide. This is essential for the survival and functions of a cell.

5.) Excretion: The cell eliminates waste products resulting from Catabolism in to the interstitial fluid. These products are carried by blood for elimination though lungs and kidneys. 

6.) Irritability and contractility: The cell is active by means of these two functions. The cell responds To any stimulus ( like physical, chemical, thermal, electrical and mechanical,) by contracting. Or the impulse is conducted as that occur in a nerve cells.

7.) Reproduction: After growing To an optimum size, the cell divides in to daughter cells. Reproduction of cell occurs by mistosis or meiosis.

MITOSIS:-

This occurs in four stage namely prophase, metaphase, anaphase and telophase. 

1.) Prophase: Intially, the centrosome divides in to two. These two new centrosome move away from each other to the two ends of the nucleus forming two poles.

2.) Metaphase: Now, the nuclear membrane disappears The Chromosomes arrange themselves around the centre of the cell. They get attacheds to thread like structure of the centrosomes which are now at the two poles of the cell.

3.) Anaphase: The Chromosomes now divide longitudinally in two equal parts. The two groups of Chromosomes move away to the poles and get arranged around the centrosomes.

4.) Telophase: The cell become narrower at the centre to facilitate division. The there'd like structure disappears. The nuclear membrane appersb again.

At the end of telophase, the cell divides. Also the Chromosomes disappears in to the nucleus. The daughter cells grow and intrur reproduce by mistosis.during mitosis each Chromosomes duplicates . The daughter cell contains forty-six Chromosomes. 

MEIOSIS:-

It is a process of reproduction which occur in higher animals including man. It involves the fusion of: 

i) spermatozon from the male ( which contains 23 Chromosomes and ii) Ovum from the female ( which also contain 23 Chromosomes). The spermatozon and Ovum are female) gametes results in the formation of a zygote which has the normal of 46 Chromosomes ( 23 pairs ) this lead to mixing of the hereditary determine nantsv or genes from the male and female. 

Determination of sex:-

One pair of Chromosomes from the father and one pair from with the mother are sex Chromosomes. These sex Chromosomes determine the sex of the child. In the female, the sex Chromosomes are the same and are called XX . In the male , they are different and are called XY. One Chromosomes from each pair determine the sex of the child.

If the child has X Chromosomes from the mother and X Chromosomes from the father, it is a female ( XX) Chromosomes from the father it is a male ( XY).

 Q.:- How many characteristics in Group Discussion?

Ans.:- 

 Characteristics:- 

A group Discussion has following characteristics:- 

(A) Purposeful Activity: Every GD is organized for some specific purpose. The purpose is made clear to the participants in advance, and they plan the things accordingly. The discussion takes place to meet the purpose.

(B) Interactive: GD is an interactive process. Every member interacts with other members, and presents her/his views. The exchange takes place in a positive manner.

(C) Democratic Process: GD is a democratic process. Every member is free to present her/his views freely. No view is forced upon any of the members. The participant listens to the views of other members and enjoys freedom to agree or disagree with the views. However every member tries to reach onto a consensus, but sometimes The GD ends without consensus among the members. The decision is left with the audience in that case.

(D) Equitable Distribution of Participation: Each member in the GD enjoys equal rights. No one is allowed to dominate the discussion. Every member is given a fair chance to present her/his views independently. 

(E) Cooperative Process: GD is based on mutual cooperation. Every member cooperates with other members and encourages them to speak out. All the members cooperate with each other, understand and appreciate different points of views, and try to pool them together in order to develop group consensus. However disagreements do exist, but they do not lead to serious conflicts. These differences enrich the process of discussion, and broaden the horizon of group.

(F) Shared Leadership: There is no named leader of the group. The members share and perform the leadership function voluntarily. They themselves start the discussion, keep the discussion on, check the progress, and encourage shy participants to speak.

(G) Flexible: GD is flexible as compared to other forms of discussion. It is less formal in style and function. The rules can be modified according to the requirement. There is no restriction of time on any participant. S/he can take enough time to present her/his views.

Where, writes hello friends please edit and choose your text........

If you liked this blog , please leave your response in comment area........

 Alt Attribute:-

The code for inserting an image in an HTML page is imagsrc alt The alt attribute is used for a text description  of the image which describes the  image if you cannot see it.



First Condition 











Second Condition 








When your internet connection is low then the alt attribute of image tag comes in handy.

Alt attribute is an attribute that comes with text in any blog.

As you all know, for a webpage, HTML is as important as its bone of structure for a human being.

In this blog, we have mentioned 15 HTML tags that are most important for any webpage:-

Special Part

(1.) Head Tag:-

This tag contains information about the page( rather than information that is shown within the main part of the browser window that is highlighted in blue on the opposite page).


(2.) Body Tag:-

You met <body> element in the first example we created. Everything inside this element is shown inside the main browser window.


(3.) Title Tag:-

The contents of the <title> element are either shown in the top of the browser, above where you usually type in the URL of the page you want to visit, or on the tab for that page (if your browser uses tabs to allow you to view multiple pages at the same time).


(4.) Heading Tag:-

HTML has six "levels" of headings:

<h1> is used for main headings 
<h2> is used for subheadings If there are further sections under the subheadings then the 
 <h3> element is used, and so on...
Browsers display the contents of headings at different sizes. The contents of an <h1> element is the largest, and the contents of an <h6> element is the smallest. The exact size at which each browser shows the headings can vary slightly. Users can also adjust the size of text in their browser.


(5.) Paragraph Tag:-

To create a paragraph, surround the words that make up the paragraph with an opening <p> tag and closing </p> tag.


(6.) Division Tag:-

The <div> tag defines a division or a section in an HTML document. The <div> tag is used as a container for HTML elements - which is then styled with CSS or manipulated with JavaScript. The <div> tag is easily styled by using the class or id attribute.


(7.) Break Tag:-

As you have already know, the browser will automatically show each new paragraph or heading on a new line. But if you wanted to add a line break inside the middle of a paragraph you can use the line break tag <br />.


(8.) Anchor Tag:-

Links are created using the <a> element which has an attribute called href. The value of the href attribute is the page that you want people to go to when they click on the link.

Users can click on anything that appears between the opening <a> tag and the closing </a> tag and will be taken to the page specified in the href attribute.
When you link to a different website, the value of the href attribute will be the full web address for the site, which is known as an absolute URL.


(9.) Ordered Lists:-

<The ordered list is created with  the <ol> element.
<li> Each item in the list is placed between an opening <li> tag and a closing </li> tag. (The li stands for list item.) Browsers indent lists by default.


(10.) Unordered Lists:-

The unordered list is created with the <ul> element.
<li> Each item in the list is placed between an opening <li> tag and a closing </li> tag. (The li stands for list item.)
Browsers indent lists by default.


(11.) Strong Tag:-

The use of the <strong> element indicates that its content has strong importance. For example, the words contained in this element might be said with strong emphasis.

By default, browsers will show the contents of a <strong> element in bold.


(12.) Emphasis Tag:-

The <em> element indicates emphasis that subtly changes the meaning of a sentence.

By default browsers will show the contents of an <em> element in italic.


(13.) Image Tag:-

To add an image into the page you need to use an <img> element. This is an empty element (which means there is no closing tag). It must carry the following two attributes:

Src

This tells the browser where it can find the image file. This will usually be a relative URL pointing to an image on your own site.

Alt

This provides a text description of the image which describes the image if you cannot see it.

Title

 You can also use the title attribute with the <img> element to provide additional information about the image. Most browsers will display the content of this attribute in a tootip when the user hovers over the image.


(14.) Table Tag:-

The <table> element is used  to create a table. The contents  of the table are written out row  by row.


<tr> 

 You indicate the start of each  row using the opening <tr> tag.  (The tr stands for table row.)  It is followed by one or more  <td> elements (one for each cell  in that row).  At the end of the row you use a   closing </tr> tag.


<td> 

Each cell of a table is  represented using a <td>  element. (The td stands for  table data.) At the end of each cell you use a  closing </td> tag.


<th>

The <th> element is used just like the <td> element but its purpose is to represent the heading for either a column or a row. (The th stands for table heading.)


<thead>

The headings of the table should sit inside the <thead> element.


<tbody>

The body should sit inside the <tbody> element.


<tfoot>

The footer belongs inside the <tfoot> element.



(15.) Form Tag:-


Form controls live inside a <form> element. This element should always carry the action attribute and will usually have a method and id attribute too.


Special part :-

At the top of a long page  you might want to add a list  of contents that links to the  corresponding sections lower  down. Or you might want to add  a link from part way down the  page back to the top of it to save  users from having to scroll back  to the top.

Before you can link to a specific  part of a page, you need to  identify the points in the page  that the link will go to. You do  this using the id attribute (which  can be used on every HTML  element). You can see that the  <h1> and <h2> elements in this  example have been given id  attributes that identify those  sections of the page.
The value of the id attribute  should start with a letter or an  underscore (not a number or  any other character) and, on a  single page, no two id attributes  should have the same value.

To link to an element that uses  an id attribute you use the <a>  element again, but the value of  the href attribute starts with  the # symbol, followed by the  value of the id attribute of the  element you want to link to. In  this example, <a href="#top">  links to the <h1> element at  the top of the page whose id  attribute has a value of top.

-:Block printing:-

  • Block printing is the oldest method of the local application of color the textile.
  • It is very similar to the use of a rubber stamp and a an ink pad. 

-: History of block printing in India:-

  • Recordsrds show that as for back as the 12th century, sereral centres in the south, on the western and eastern coasts of India became renowned for their excellent printed cotton.


  • On the south eastern coast the brush or kalam(pen) was used, and the resist applied by the same method. 

-: Centres of Block Printing:-

The main center for block printing in India are:

1. Andhra Pradesh (kalamkari)

2.Gujarat (ajrakh)

3.rajasthan (sanganeri)

4. Madhya Pradesh (bagh print)

5.Uttar Pradesh

6. West bengal

-:Tools for block printing:-

The main tools of the printer are blocks which are available in different shapes and size as per the design and requirement.

The block makers mainly make two types of block:

1.wooden block 

2.metal block



-: Colours/dyes for block printing:-

The process of block printing is widespread due to its intricate process, motifs and vibrant colour.
The main raw material is the colour used in the printing traditionally the artisans used natural colours but today it has been replaced by chemical and artificial colours.

:The main raw materials are colours/dyes:

Different types of dyes are used for silk and cotton.

1.Vegetable/ natural dyes:-

Since ages artisans are using vegetable dyes for printing and dying. As they are extracted from the nature, vegetables, fruits etc. They are beneficial for the environment along with having traditional importance. There are few major colours produced naturally which are known internationally too.

Indigo Blue:-

Extracted from the Indigo plant faund throughout India.

Red :- 

This is obtained by mixing alizarin with alum. The colour ranges from pink to deep red.

Black:-

This is acidic solution of iron which is obtained by Processing rusted nails, horse, shoes, iron scrap etc. With jiggery and salt.The mixture is buried under the ground and allowed to rot for about 10 - 15 days. It is then taken out and the colour is prepared. 

Green:-

The skin of pomegranate is processed by boiling. Apart from this artisans also use bark of mango tree,vinegar, slaked lime etc.

2.Discharge dyes:-

These dyes are used to print on dark background. The printing colours have chemical which react with the dark ground fabric and bleaches out the dark colour from that particular place and prints the desired colour. In this process a range of white and other light colour can be printed on a dark background.


3.Pigment dyes:-

These colours are readily available in the market  and are easy to use. The mixed colour can be stared in plastic buckets after use. Pigment colours, brought from the market are further mixed with kerosene and a binder. The mixing has to be done carefully as the thickness of the material can give raised effects on the cloth while printing. These colour fallow the direct printing technique. Colour applied are visible and do not change after washing. A number of colour can be obtained by mixing two or more pigment colour.


4.Reactive dyes:-

These are the chemical dyes which when mixed with second chemical produces a third colour. Artisans therefore dye the cloth, to be printed, in one chemical and then print it with another chemical. These two chemicals react with each other and hence produce a different colour. These are only few chemical dyes available in the market.


5.Rapid fast colours:-

These colour are difficult to store and has to be used the same day. In rapid fast colour process the colour in the design and the ground colour both are printed in one go. Generally white or light background is used. There are only few colour, available in this process.


-: Process of block printing:-

The process of printing can be divided in to fallowing major parts:

(A) washing 

(B) marking

(C) printing

(D) Drying

(E) washing 

(a) Washing :-

The fabric brought from the market contains starch, dust etc. Therefore it goes through a pre - printing treatment in order to get good results while printing. The fabric is therefore dipped in a solution of water and bleach for 1- 2 days. It is than boiled and washed with water. Finally the cloth is stretched and spread on ground and left for drying. This process known as hari sarana takes 3 - 5 days depending on the weather conditions.

(B) Marking:-

The cloth to be printed is spread on the printing table and fixed with the help of pins. With help of scale and chalk areas to be printed are marked and proper gaps are left for cutting and stitching.


(c) printing:-

Printer dips the block in the colour and stamps the design on the cloth. The block are then pressed hard with the fist on the back of the handle so that registration/imprint of the colour is even. 

  • Printing starts from left to right.
  • Number of colour used in the design defines the number of blocks to be used.
  • First outline colour is applied and then the filling colours. Specific point in the block guides the printer of the repeat impression. The process of printing is called as- Chapaai.

(D) Drying:-

After the printing is completed the fabric is dried out in sun for the colour to get fixed. This is done specially for the pigment dyes. The printed fabrics are handled with utmost care so that the colour are not transferred to other areas, therefore they are wrapped in plastic or newspaper after dying. The process is called as - sukhaai.

(E) washing:-

Fabric then goes through the process of steaming in the special boilers constructed for this purpose. After steaming, the material is washed thoroughly in large quantities of water and dried in the sun. Once the fabric is washed and dried ironing is done, which further fixes the colour permanently. This final Process of washing is called - Dhulaai.


-:Advantages of block printing:-

1.Beautiful effects can be created.

2. Bright and colourful prints are obtained.

3. Any number of blocks can be used not only for different colour but also for different shade in the same colour.

4.Any type of design can be made with blocks .

5. There is no restriction in the sizeand  shape.

-:Disadvantages of block printing:-

1. Not able to give minute details to the design.

2. Absence of delicate shading and gradation.

3. Slow output and high cost.

4. Inability of perfect joining.

 Q.:- What is the importance of Group Discussion?

Or

What do you understand from Group Discussion?

Ans.:-

Introduction:-

You might have found people discussing social, religious, political or economic issues at a restaurant, bus stop, canteen, tea stall, club, etc. We too discuss various matters in our daily life with our friends, relatives, family members, and others. Even family members also discuss family matters at home. These discussions can be informal as well as formal. Informal discussions take place in informal setting whereas formal ones take place in formal setting, like at the office, a conference hall, or a recruitment centre. When a group of people deliberately come together to have discussion on a specific matter in a formal setting, it may be called Group Discussion.


Group discussion, or popularly known as GD, is a group activity in which a small number of persons form a group to exchange their views, opinions, knowledge and information on a particular issue, topic, problem or situation. The exchange takes place through spoken words. Each member is given a fair chance to speak and express her/his opinion. S/he listens to the other member as well as shares her/his own views. Since the number of participants is small, it is not difficult to involve every member in the discussion. The group members interpret, analyze and argue so as to discuss the topic or case threadbare as a team. It is a team activity just like a football match where player passes the ball to her/his team member and aims at a common objective.

GD is formal and systematic. There is no room for emotional outburst or excitement in the discussion. The discussion contains self-imposed discipline, and greater responsibility lies on participants' shoulders to make it effective. Generally, there is no named leader of the group. As the discussion proceeds, one of the participants emerges as a leader. But sometimes a person is assigned the responsibility to moderate the discussion. S/he or some other person can evaluate the contribution made by each participant as well.

Number of Participants:-

It is difficult to specify the number of participants to make a group discussion fruitful. However, there can be ten or more participants, but, in that case, some tend to avoid participation and remain mere listener(s). The discussion may lose its significance because each participant would not present her/his views. Researches reveal if the number is kept between 5-9, fruitful discussion can take place. If there are less than five participants, the discussion can lack diversity of views and opinions.

Objectives:-

GD is a goal-oriented activity. Each participant is usually aware of the objective beforehand. The goals are generally decided before the conduct of GD. But main objective of GD is to provide a wide range of solutions to a particular problem and reach at a viable amicable
solution. But sometimes the participants fail to reach at a consensus; the decision is left with the audience in that case.

Besides decision making, it helps in eliciting personality traits of the participants. That's why several companies conduct GDs in order to find out the qualities they are expecting from the prospective employee(s). A group of short-listed candidates is given a topic which is usually debatable and of current importance. The candidates have to speak on the topic within a limited period of time which ranges between twenty to forty five minutes. An
observer, appointed by the prospective employer, sits through the discussion and Judges each participant's communication skills, tolerance, leadership qualities, intellectual ability, group behaviour, and approach to solve problems. The candidates are screened on the basis
of their performance.


Group discussion is also an instrument of education to develop and judge the students'
personality traits. It trains the students to function in the professional world efficiently.
Many educational institutions also use GDs for the screening of candidates for admission
to a particular course. It is used apart from the written test and/or interview.

Ways to Organize a Group Discussion:-

There are two ways of organizing a group discussion: first, the topic is announced before the discussion, and the participants come prepared for the discussion. Second, the topic is announced on the spot. The participants are given five to ten minutes to collect their
thoughts. But in both the cases, the exchange takes place in a systematic and structured way. The chairs are arranged in a circle so that every participant can observe the expressions of other participants.


Example:-
Group Discussion on the topic: "Impact of TV Serials”
(Five persons- Ashok, Shreya, Swati, Mahesh and Rohan-are the participants.)

Ashok  :  Hello everybody! We are here to discuss the impacts of TV serials. As all of us know, television is the most reachable means of mass entertainment that has gripped the nation by wide range of coverage and has been yielding fast and great impact on the society. With the expansion of TV network, the culture of TV serials appeared. These serials have many interwoven stories or sometimes past and present is amalgamated to extract maximum publicity among the viewers. These are so popular among urban, semi-urban, and rural populace that sometimes viewers miss a professional appointment but not the serial. Most of the serials are set in high society, sophisticated settings, with modern furniture, expensive dresses, jewelry, cars and luxurious lifestyle. Serials set trends among the young people who ape everything, which appeal their instinct. They watch latest fashion and etiquettes in the serials and follow them.

Shreya  :   You are right Ashok, but this pomp and luxurious life-style has been degrading the youth. They try to grab these luxuries by hook or crook. They take short cut route to become rich, and sometimes use unfair means to grab it. This is because of the impact of TV serials.

Swati  :  But serials also inculcate moral values among the viewers. We can take examples of the serials, 'Ramayana' and 'Mahabharata. These religious serials provide information on our past in a new perspective especially to the young generation. Historical serials, like 'Akbar the Great'. "The Sword of Tipu Sultan' and 'The Great Maratha supply the saga of our past.

Mahesh : I agree with my friend, but what about the serials based on Saas-Bahu saga. These are set in the traditional India n social household environment, particularly highlighting the joint family aided and with myriad problems, ranging from petty clashes to intrigues and adultery. These are responsible for the disintegration of social values and joint-family system. Adventurous serials, like 'Shaktimaan, create waves among the children and they try to act like the character in the serial. Many children had to lose their lives in the pursuit. In order to add sensation, the producer tries to give a new fillip that shows something unhealthy or unconventional.

Rohan  :  It cannot be denied that serials kill precious time of youngsters as well as professionals, but they have greater place in modern life. There is a greater need that the serials must be intended to preserve social values rather than spoiling them in the race of minting money.

Some GD's have a person as moderator who moderates the discussion. S/he makes sure that the participants are not going off the track. S/he acts like a leader and triggers passion among the participants. S/he remains supportive and sympathetic towards them.

After completion of the discussion, s/he provides feedback to the participants, in five point scale, (5 for excellent 4 for very good, 3 for good, 2 for average, and 1 for below average). S/he rates the participants on the basis of confidence, attitude, communication skills,
interpersonal skills and intellectual knowledge. S/he provides honest feedback to each participant without any prejudice. S/he does not judge any participant by his/her own appearance or academic achievements, rather remains impartial and free from pre-conceived notice.

Example:-
Group Discussion on the topic: "Need of Distance Education in India" (Seven persons- Anuj, Bhavya, Charu, Dinesh, Ekta, Faizan and Gurpreet- are the participants. The GD is moderated by Sakshi).

Sakshi : Good morning friends! Today, we shall discuss on the need of distance education in India. As you know, in spite of a large number of colleges, formal system of education failed to reach the masses. An urgent need was realized to develop some system that can meet the rising demand of education. So, India developed a new system which has been named as 'education through distance mode. It has proved a boon for Indians. A large number of people have been getting education through this system. The government has started 'open schools' and 'open universities' for the students who cannot take formal education, or fail to secure admissions in regular colleges to study further.

Charu  :  You're right Sakshi! But would the students reap the benefit of regular classes? No! They'll not be able to get the advantage of classroom teaching.

Dinesh  :  My dear, it's not there. They attend PCP classes on Sundays and holidays. They come with their doubts, and teachers clear the doubts. Moreover, they study through radio and television. Many open schools and universities relay their programmes through mass media. They send their study material to the students which consists of very high quality.

Charu  :  But what about practical classes?

Gurpreet  :  You are not aware Charu. Most schools and universities provide the facility of laboratories as well. Students visit the study centre and perform their practical there. They remain open in Sunday and holidays.

Sakshi  :  Bhavya, you want to say something. Please share your opinion.

Bhavya  :  This system is beneficial for the students who work somewhere. They take their jobs during week days and attend their classes on weekends.

Ekta  :  But do the universities and employers consider their degrees equal to the degrees of regular courses? Some employers consider their degrees inferior to that of earned through regular classes.

Faizan  :  No Ekta. It's not there. Their degrees have equal weight. The students get admissions, jobs, and promotions on the basis of the degrees provided by the open schools and open universities.

Sakshi  :  What're your views Anuj?

Anuj  :  As a developing country, India has several impediments. Some of them are high illiteracy rate, growing population, poverty, and limited resources. Two third of India's population reside in villages. Government cannot provide school and college in every village. However the government is trying its best, but it's difficult to reach to every individual with education because of limited resources. Distance education is a boon for those who reside in far flung areas or villages. Moreover, women are not allowed in villages to attend schools or colleges because of orthodox mentality. Distance education provides them an opportunity to continue their studies.

Sakshi  :  I do agree with all of you. The limitations of formal system of education have led to the inception of distance education. It has absorbed the students who could not find admission in regular colleges, could not continue their studies, or so. However it may have some limitations, but it is really beneficial for the students.


Thanking you for read my blog 😁😁

 -:Roller printing on textile:-



Roller printing:-

Also called cylinder printing or machine printing, on fabrics is a textile printing process patented by thomas bell of Scotland in 1783 in an attempt to reduce the cost of the earlier copperplate printing. This method was used in Lancashire fabric mills to produce cotton dress fabrics from the 1790s, most often reproducing small monochrome patterns characterized by striped motifs and tiny dotted patterns called machine grounds.

  1. Improvements in the technology resulted in more elaborate roller prints in bright, rich colours from the 1820s; turkey red and chrome yellow were particularly popular.
  2. Roller printing supplanted the older woodblock printing on textiles in industrialized countries until it was resurrected for textiles by william marrise in the mid - 19th century.

-: Engraved copperplate printing:-

The printing of textiles from engraved copperplates was first practiced by bell in 1770. It was entirely obsolete, as an industry, in England, by the end of the 19th century. The presses first used were of the ordinary letterpress type, the engraved; plate being fixed in the place of the type. In later improvements the well - known cylinder press was employed; the plate was inked mechnically and cleaned off by passing under a sharp blade of steel; and the cloth, instead of being laid on the plate, was passed round the pressure cylinder. The plate was raised in to frictional contact with the cylinder and in passing under it transferred its ink to the cloth. The great difficulty in plate printing was to make the various impressions join up exactly; and as this could never be done with any certainty, the process was eventually confineed to patterns complate in one repeat, such as hand kerchiefs, or those made up of widely seporated objects in which no repeat is visible, like for instance,patterns composed of little sprays, spots, etc. Larger machines printing from two to sixteen colours are precisely similar in principle to the above, but differ some what,in detail and are naturally more complex and difficult to operate. In a twelve colour machine, for example,twelve copper rollers, each carrying one portion of the design are arranged round a central pressure cylinder, or bowl, common to all,and each roller is driven by a common driving wheel called the crawn wheel actuated, in most cases, by its own steam - engine or motar another difference is that the adjustment of pressure is transferred from the cylinder to the rollers which works in specially constructed bearings capable of the following movements capable of the following movements.


  1. Of being screwed up bodily until the rollers are lightly pressed against the central bowl;
  2. Of being moved to and from side ways - so that the rollers may he laterally adjusted; and 
  3. Of being moved up or down for the purpose of adjusting the rollers in vertical direction. Not with standing the great latitude of movement thus provided each roller is furnished with a box wheel, which serves the double purpose of connecting or gearing it to the driving wheel, and of affording a fine adjustment, each roller is further furnished with its own colour - box and doctors.
  4. With all these delicate equipments at his command a machine printer is enabled to fit all the various parts of the most complicated patterns with an ease, dispatch and precision, which are remarkable considering the complexity and size of the machine.
  5. In recent years many improvements have been made in printing machines and many additions made to their already wonderful capacities. Chief amongst these are those embodied in the intermittent and the duplex machines. In the former any or all of the rollers may be moved out of contact with the cylinder at will, and at certain intervals. Such machines are used in the printing of shawls and sarries for the Indian market. Such goods require a wide border right across their width at varying distances sometimes every three yards, sometimes every nine yards and it is to effect this, with rollers of ordinary dimensions, that intermittent machines are used. The body of the sarrie will be printed, say for six yards with eight rollers; these them drop away from the cloth and others, which have up to then been out of action, immediately fall in to contact and print a border or crossbar, say one yard wide, across the piece; they then recede from the cloth and the first eight again return and print another six yards, and so on continually.
  6. The duplex or reversible machine derives its  name from the fact that it prints both sides of the cloth. It consists really of two ordinary machines so combined that when the cloth passes, fully printed on one side from the first, its plain side is exposed to the rollers of the second, which print an exact duplicate of the first impression upon it in such a way that both printings coincide. A pin pushed through the face of the cloth ought to protrude through the corresponding part of the design printed on the back if the two patterns are in good fit.
  7. The advantages possessed by roller printing over all other processes are mainly three firstly, its high productivity, 10,000 to 12,000 yards being commonly printed in one day of ten hours by a single - colour machine; secondly, by its capacity of being applied to the reproduction of every style of design, ranging from the fine delicate lines of copperplate engraving and the small repeats and limited colours of the perrotine to the broadest effects of block printing and to patterns varying in repeat from I to 80 in, and thirdly, the wonderful exactitude with which each portion of an elaborate multicolour pattern can be fitted in to its proper place, and the entire absence of faulty joints at its points of repetition consideration of the utmost importance in fine delicate work where such a blur would utterly destroy the effect.

Engraving of copper rollers:-

The engraving of copper rollers is one of the most important branches of textile printing and on its perfection of execution depends, in great measure, the ultimate success of the designs. Roughly speaking, the operation of engraving is performed by three different methods, viz.

  1. By hand with a graver which cuts the metal away;
  2. By etching in which the pattern is dissolved out in nitric acid;
  3. By machine, in which the pattern is simply indented.

The end....
