The mechanical properties of jean slacks to the type of cutting lines in knee region and the bending time, after doing bending 0 times, 500 times, and 1500 times, the effects of whether or not cutting line, the fabric direction of the cutting area, and the number of cutting lines were investigated for tensile, shearing, compression, and mixing value of mechanical properties. The results are as follows: EM to bending times were larger in order of weft<wp/wf 1<wp/wp 1<warp<wp/wf <wp/wp 2<bias. G to bending times were influenced by the number of cutting lines to the shearing which entails tensile property more than bi-axel. Regardless of fabric direction, the sample of 2 cutting line showed very lower G than 1 cutting line sample. WC to bending times were larger for wp/wpl sample than other samples. RC to bending times decreased for 1 cutting line sample but increased continuously for 2 cutting line sample except at the times of 1000. 2HG/G, the combination of mechanical properties decreased as bending times increased. W/T were small in 1 cutting line sample, both before and after bending. As to shrinking of cut area after 1500 time bending, wp/wf 1 sample showed larger shrinking in weft than in warp. The shrinking of wp/wf 2 sample were larger in weft. wp/wp 1 and wp/wp 2 samples showed equal shrinking in warp and weft.

To propose a basic material that can improve the crumples in the knee area and can be applied as an element of garment design, the present study examined the elongation rates of the samples by differentiating the number of cutting lines according to the direction of the fabric, and then determined the puckering phenomenon by judging the conditions of the seams based on the looks of seam lines after bi-axil elongation. After the subjective evaluation on the knee areas of both the standard and modified trousers, the following conclusion was drawn : The elongation rates of the samples are: warp (3.98%)<warp1 (4.29%)<weft1 (5.30%)<weft (5.82%)<warp2 (5.68%)<bias (6.96%)<weft2 (8.64%). The samples in the warp direction: as the cutting lines increase, the elongation rate grows by 1.4%. The elongation rates of the samples in the weft direction: the sample with one cutting line has 0.52% lower rate than that in the weft direction without cutting line; that with two cutting lines has 1.68% higher rate than that running on the bias. The subjective evaluation on the knee areas: the subjects wearing the standard trousers feel more comfortable when sitting on a chair (0.2) >cross-legged (-0.2) > squatting down (-0.4); those in the modified trousers feel more comfortable when sitting on a chair (0.2) > cross-legged (0)> squatting down (-0.6). In the cross-legged posture, the modified trousers (0) has higher scores in the subjective evaluation than the standard ones (-0.2). The evaluation on the looks of needleworks in the samples with cutting lines along the direction of the fabric: weft2 (5.0)<weft1 (4.8)<warp1 (3.8)<warp2 (2.8).

개인화 기술은 과다한 정보를 줄이기 위한 여과 기술로서 최근 인터넷 사용자들과 정보 제공자들로부터 관심의 대상이 되고 있다. 그 중 가장 많이 사용되고 있는 개인화 기술은 협력적 추천으로서, 이 방법은 사용자에게 어떤 항목(상품)을 추천해주는 데 있어서 그 사용자의 다른 항목들에 대한 선호도나 추천 항목에 대한 다른 사용자들의 선호도를 이용하여 추천해준다. 협력적 추천 방법 중 보편적으로 많이 사용되는 최근접 이웃 방법은 유사한 사용자들의 행위에 기반하여 항목들을 추천해 준다. 그러나 이 방법은 사용자들간의 단순한 유사도를 계산함으로써 성능이 떨어지는 문제점이 있다. 데이터마이닝 기법을 적용하여 사용자 선호도 데이터로부터 추천 규칙을 생성하여 추천을 해주는 연관규칙 방법 또한 사용자나 항목간의 내용적, 분류적인 공통성 또는 개념에 의한 연관성을 고려하지 못하고, 단지 단순하고 표면적인 연관성만을 고려하는 문제점을 가지고 있다. 본 논문에서는 추천의 정확도를 향상시키기 위한 신경망 추천 모델을 제안한다. 신경망으로는 다층 퍼셉트론을 사용하여 우선 학습변수들과 입력차원의 변화에 따른 신경망에 기반한 협력적 추천의 성능에 대해 조사하고, 순수한 협력적 추천에서의 문제점인 희소성(sparsity)문제를 해결하기 위해 내용기반 추천과 협력적 추천을 병합한 모델을 신경망에서 보인다. 마지막으로 다른 협력적 추천 방법과의 비교를 통하여 본 신경망 추천 방법의 장점과 성능의 우수함을 보인다. Personalization is a filtering technique to reduce information overload and it recently draws attention upon internet users and information providers. The collaborative recommendation is one of the widely used personalization methods. It recommends a user an article based on other users preferences for the target article or the preferences for other articles of the target user. The nearest neighbor method is one of the common collaborative recommendation methods, which recommends articles based on the behavior of the similar users. However, it suffers from poor performance mainly because it fails in properly computing similarity between users. The rule method extracts recommendation rules from the users preference data using data mining technique. It also suffers from simple and superficial association between users or articles without utilizing conceptual level of association such as commonality in contents and category. In this paper we propose neural networks model to improve the accuracy of recommendations. We investigate various aspects of collaborative recommendation based on multi-layer perceptrons by varying parameters and the dimension of input data. We also combine the collaborative recommendation and the content-based recommendation within a neural network model to solve sparsity problem in pure collaborative recommendation. We finally demonstrate through experiments that the neural network based collaborative recommendation outperforms the existing methods.

진 슬랙스 구입 및 수선에 관한 실태조사 : 18~23세 남녀 학생을 대상으로 Targeted of the Male and Female Students with in Age Group between 18 and 23

이정숙,성수광 한국의류산업학회 2003 한국의류산업학회지 Vol.5 No.2

Compared with male students, female ones perceive themselves to be heavier in the lower part than in the upper part of the body, and have round belly, thick thigh and big calves. 61.2% of the male students buy their jean slacks based on their waist size, while 76.6% of female students do it based on their hip size. Those who are in the range of shorter heights tend to choose their jean slacks by their hip sizes, while those in the range of taller heights tend to buy them by their waist sizes. Most female students repair their jean slacks in the waist(61.8%) and/or length(60.4%). Male ones tend to repair them in the hip area(76.2%) and/or crotch(72.1%). The areas of repair are different by age: group A4 repair mostly in the waist(32.7%), while 40.3% of the students in group A3 tend to change any area they like, such as in the hip(38.1%), length of slacks(33.6%), or crotch(45.2%). Female students seem to feel uncomfortable in jean slacks in all the areas but waist. By age, group A1 seem to feel uncomfort in the crotch(31.4%); group A3, in the waist(41.9%), hip(32.0%), knee(33.3%) and thigh(34.2%). The students in group H1 tend to feel more comfort in the waist(28.4%), while those in the group H3, in the thigh area(30.3%). The area that would make jean slacks more comfortable was the waist(61.4%) in the male students, and the thigh(61.7%) in the female students. By age, the area that needs more ease was the waist(40.8%) in group A3; the tummy(35.1%) and thigh(33.0%) in group A4, and; the crotch(29.8%) in group A1. By height, group H1 need more ease in the waist(38.6%); group H2, in the tummy(44.6%), and; group H3, in the crotch(37.2%).

가치정향위기 시대에 있어 교육의 목표와 과제

安正秀 慶熙大學校 1997 論文集 Vol.26 No.-

This study attempts to analyze the interrelationship between the value-orientation of man and the purpose-orientation of education. It demonstrates the importance of good value-attitude as the prerequirement of good education, which comes under influence of the spirit of the time as well as the inner state of modern man. From aspect on the spirit of the time, three dimensions are focused: cognitivism, egoistic individualism, and hedonism. From aspect on the inner state, the existential vacuum, an "abyss-experience", which is both increasing and spreading, is focused. As the main point of study is to examine the actual goals is the very act of education from the viewpoint of value-orientation, two kinds of goal-complex undergo the examination: the one is "emancipation", including such relevant ideals as "democratization","humanization", and "criticism", and the other is "self-actualization", presented as the general objectives in the curriculum of school education. The former is proved to be destructive to public value-orientation, the latter to be rather ego-oriented. Both notions turns out to be inappropriate for the goal-presentation in the field of education, because they do not meet the formal requirements of it. Educational goals must represent the personality-ideals, which should be pursued, not political ideals, and be formulated in terms of outcomes of educational activities, not processes. Educational objectives and tasks in an age of value-orientation crisis should be more common-good oriented, subject to the ground-ideal of our society.

이정숙,성수광 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.3

This is the result of the comparison of the number of jeans, colors, images, opinions when it was purchased, shapes according to the gender of persons in jeans. According to the gender, male students had 1.64 jeans(46.3%) and female students had 2.09 jeans(53.7%) on the average. Male students selected colors of jeans which they don't have, but want to wear once in the order of blue(3.7%), red(21.0%), white(24.1%), black(25.6%), and others(25.6%). Female students selected colors in the order of blue(3.2%), hlack(15.6%), red(24.8%), white(27.7%) and others(25.6%). In case of the general image about jeans, male students thought the jeans as masculine(1.2%), sexy(3.1%), unisexual(3.2%), active (23.6%), young(29.8%), and comfortable(36.5%) and female students thought it as masculine(0.3%), sexy(3.5%), unisexual (10.4%), young(21.9%), comfortable(28.1%) and active(35.8%). Male students considered torn or holed jeans ill-mannered (10.7%), delinquent, (20.7%)trendy(21.0%), comfortable(22.9%), and dandy(24.7%). Female students think it ill-mannered (3.4%), delinquent7.1%, trendy(17.4%), comfortable(21.I%), and dandy(50.9%). When they purchase jeans, male students choose according to trends(17.9%), don't consider design(19.5%) and look for their own styles(62.6%), female students didn't consider design(5.2%), choose according to trends(22.0%), and look for their own styles(72.5%). The designs of jeans which they usually wear were bell bottom(1.5%), wide-shaped(7.4%), baggy(17.5%), straight-shaped(73.6%) in case of male students, on the other hand, in case of female students, baggy(10.2%), wide-shaped(11.0%), hell bottom(17.0%), and straight-shaped(61.8%). The designs of jeans which they didn't have but want to wear once are wide-shaped(10.1%), bell bottom(13.2%), baggy(20.9%), and straight-shaped(55.2%) in case of male students. On the other hand, females students want to wear baggy(11.6%), wide-shaped(15.0%), straight-shaped(27.6%), and bell bottom(45.8%). The above-mentioned findings illustrated that both male and female students regarded blue as the original color of jeans, but they wanted to wear jeans in colors other than blue. In the past, jeans were considered masculine and unisex, but they viewed jeans as an apparel that was comfortable to wear and made it easier to move. Female students had a higher tendency to be fashionable than male students, and their preference for jeans was consequently different. Jeans manufacturers should take those characteristics into account to produce products in different colors and form.

實存分析的 精神治療法으로서의 로고쎄라피(LOGOTHERAPY)

安正秀 慶熙大學校 1980 論文集 Vol.10 No.-

Logotherapy, or existential analysis (Existenzanalyse) as it also has been called by its founder, Viktor E. Frankl of Vienna, is referred to by many authors in terms of the Third Viennese School of Psychotherapy. To Frankl, 'logos' means meaning, and logotherapy means 'healing through meaning'. Logotherapy is based on the three concepts. (1) the freedom of will, (2) the will to meaning, and (3) the meaning of life. The freedom of will involves the issue of determinism versus pan determinism, the will to meaning is explained as distinct from the concepts of the will to power and the will to pleasure as they are presented by Adlerian and Freudian psychology. Criticizing the will to pleasure (the pleasure principle) in the light of a broader concept, the homeostasis principle. Frankl elaborate on logotherapy's motivationsl theory. The meaning of life relates to the issue of relativism versus subjectivism. The therapeutic applications of logotherapy are also threefold. First of all, logotherapy is applicable as a treatment of noogenic neurosis; second, logotherapy is a treatment of conventional psycho-genic neuroses; and third, logotherapy is a treatment of somatogenic diseases in general. Today, however, ever more patients complain of sense of meaninglessness or emptiness which Frankl has termed existential frustration. Existential frustration need not but may well result on neurosis in which case Frankl speaks of a 'noogenic neurosis' in contrast to the conventional one. According to empirical studies in various countries, about 20percent of the cases of neurosis accuring in clinics are noogenic. In such cases, logotherapy is the method of choice. Drawing upon his many years of professional practice and the concentration-camp experiences that helped shape his view, Frankl developed such invaluable therapeutic techniques as paradoxical intention and dereflection in addition to traditional therapy. In an age such as ours, in which traditions are on the wane, counseling and psychotherapy must see its principal assignment in equipping man with the ability to find meaning. The search for meaning is a never-ending process to make sense of life, in spite of apparent chaos and unavoidable suffering. To help people in this search has always been the goal of religion. Logotherapy, as a branch of psychotherapy, extends its help to everybody, religious or not, because the search for meaning is a prerequisite for health. In this respect, we come to a concluding remark that logotherapy speaks to the needs of the hour.
