We developed a pattern drafting computer program using a popular CAD program for the purpose of the automatic manufacturing and education based on the concept of the easy -order-system which can easily reflect body characteristics and design favors of individuals to the ready-made clothing. The programs were written in Auto LISP which can utilise most of frictions of the Auto CAD, and the result of the design for an full-pleated skirt was shown. Also, we devised an easy way to set the location of reference points by inputting of tangential angle only for the use of the cubic spline curve which can represent body shape very well. Finally, by marking down all of symbols needed in manufacturing process, we completed the automatic pattern drafting program to make it useful as an industrial pattern without any amendment or correction in cutting and sewing operation.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. Thus, design, comfort and economical efficiency are important factors of shoes. Consumers can choose suitable shoes for their feet in off-line shopping. However, in on-line shopping, because they can not wear shoes, compare to the off-line shopping, there are many problems in internet shopping. First, consumers can get limited information of shoes because they must search information of purchase without other's help. Second, because consumers can not get important information such as design, size and a comfort of wearing, they can not make a careful decision. Above these, the solution of user-oriented internet shopping is development of new type of prototype which is accessible to user and to offer visual information through 3D-virtual reality. The purpose of this study is to develpoment of shoes easy-order prototype so to reduce of internet shopping risk and offer to shopping convenience. Contents of the new prototype are as follows; 1. Consumers can print out a foot shaped plane figure and compare it to their foot. If the size of printed sheet is not proper, consumers can choose another size. Through this step, they can get their own size. 2. In 3D-virtual reality, consumers can get a various visual information. So they feel wearing comfort indirectly. It is expected that the result of this study would be an important case study to develop of shoes' easy-order prototype for a disabled person.

In creating an avatar, consumers can find out for themselves their own sizes to be entered. Also, putting in a face creation main-page menu option enables clients to make up their faces and match them to their bodies. Through this process when purchasing clothes through the internet consumers can enter their own body sizes and create avatars that are identical to their body shape. The uniqueness of developed prototype is that it creates an avatar similar to one's body shape according to body size inputs and demonstrates visually to customers the on-line comfort test which was only available off-line traditionally. The avatar follows the movement of mouse from left to right which enables 3 dimensional visualization. Through maximizing the visual effect this research focuses on enabling consumers to feel subjective parts as if they are off-line. This study seeks to provide a type of prototype of an online shopping mall that meets the demand of the consumers using the 3D avatar.

The entropy measure is considered to denote the uncertainty of order statistics filters and choose the length of consecutive order statistic filters. However, it needs much calculations to get the amount of the entropy of all possible sets of consecutive order statistics, and the results of those calculations return many numerical values. Thus we provide an efficient graphical presentation of those numerical values, which make it easy to understand the distribution of the entropy among order statistics.

The purpose of this study was to investigate the teachers’attitudes toward the middle and high school student uniform. The questionnaire included independent variables about teacher themselves and school surroundings, and questions about teachers’attitudes toward school uniform. The participants were 316 middle and high school teachers in Chonbuk province. Means, standard deviations, frequencies, and percentages were calculated. ANOVA test was used for differences and scheffe-test was followed. The results were: 1. Teachers were content with “Students in uniform are upright and look more studentlkie.”“It’s easy to supervise students outdoors.”, and “There’s few efficiencies in coping with the temperature alternating.”, “Students in uniform hardly can reveal their originality.”and “It’s inconvenient for the students to be dynamic in uniform.” 2. Teachers in high schools and in private schools showed more positive attitudes toward uniform. And the male teachers, teachers graduated from general college, married teachers, and teachers who have a career of more than 20 years showed more positive attitudes toward uniform. More variables concerned about teacher themselves showed more significant differences than those about school surroundings. 3. Most of teachers showed positive attitudes toward uniform. The rank order of the reasons for the teacher’s positive attitudes were “Students in uniform are upright and look more studentlike.”, “It’s easy to supervise students outdoors.”, and “There’s no noticible distinction between the rich and the poor students.”The rank order of the reason for the teachers’negative at titudes were “Student in uniform could hardly reveal their originality.”, “It’s inconvenient for the student to be dynamic in uniform.”, and ”As they have to get the street clothes besides, economic burden becomes double in reality.”4. More than half of the teachers who are working at schools with uniform showed positive attitudes toward uniform. The rank order of reasons for the teachers’positive attitudes were “Students in uniform are upright and look more studentlike.”,“It’s easy to supervise students outdoors.”and “Economic burden could be decreased.”“The rank order of the reasons for the negative attitudes were “It’s inconvenient for the student to be dynamic in uniform.”, “Students in uniform could hardly reveal their originality.”, and “Students cannot feel free in mind with uniform.”5. Teachers overall showed positive attitudes toward uniform whether they work ar schools with uniform or without it.

In most of the modern libraries throughout the world, it is popular to adopt the author number which arranges the books or entries in alphabetical order of their author's names within the same ultimate class. However, viewed historically, that was the Western practice never used in the East before. Traditionally chronological order was followed in the East. Book number not only individualizes the books within the same class but also makes it easy for the user to choose and find out the relevant materials. In this respect, chronological book number is decidedly superior to all kinds of book number systems ever have been existed. Especially in these days of rapid obsolescence of documents and with serious problems of storage of documents, the chronological order seems to be the most modern and future-oriented of all other book number systems because it distinguishes clearly new materials from aged materials by the date of publication and controls the stack spaces mechanically and effectively. This writer devised New Chronological Book Numbers adaptable to both the Eastern and Western materials, and the system has been adopted at Yonsei University Library. The features of the system are as follows: (1) It is easy to type the call number in cataloging the Eastern and Western materials. That is because the structure of the chronological number is pure numerical notation by taking the last two figures of the year within twentieth century(e.g. 85 for AD 1985), that is 1900s, and the last three figures of the year from twenty-first century to thirtieth century, that is 2000s. (2) It does not make all classes have chronological number uniformly. Within the classes for individual biographies, genealogies and collections of biography of specific family, books about individual organization, individual literary and artistic works, philosophical works of the famous philosophers, books and its facsmile editions published before 1900, new editions, translations, commentaries, serials, chronological number is assigned to the author number as in the past. (3) It separates the Eastern materials from the Western materials and makes the typing easy in cataloging. That is because the subarrangement within the same chronological book number is made by the accession order which uses 'panjol-ponmun' or the characters of basic syllabic table of Korean alphabet in case of the Eastern materials and Roman alphabet in case of the Western materials.
