Since aging has become one of most hot and serious issues in the whole global world, universal design as a strategic concept to enable the elderly age in place has received much attention and its importance is getting recognized. Japan has undergone the Aging phenomenon much earlier than Korea and other countries. During that time, through much trials and errors, it accumulated the wisdoms and techniques to precede aging friendly environment and products. Therefore current Japan house is a comprehensive setting which embraces lots of universal design features that has a valuable implication for Korean development that faces fast aging future. The purpose of this study was to delineate characteristics of universal design features appeared in Japanese Model houses. One site of housing park in the city where various model houses of representative housing construction companies was selected as a cluster area for data collecting. Data were collected mainly through field survey at the housing park of Tokyo during November, 2006, and additional data were collected through website and company information of relevant company. Universal design features were extracted for 17 houses of the housing park and sorted and analyzed according to the analysis frame. The frame were made using 2 major clusters; space area, and 8 universal design principle. Results showed a range of universal design feature and its detail universal design principle satisfied. The 8 principle currently developed became to house realistic practical examples and theory became proved its impractical power. The academic, educational and industrial implication were documented.

The present study aims to provide an analytical framework for achieving aid and development effectiveness of agricultural cooperation with a demand-oriented perspective. This paper pays particular attention to categorize the stages of agricultural development of African recipients to identify demands for agricultural aid of the categorized groups. To do so, first of all, it establishes theoretical background to apply the demand-oriented concept and utilize the phase of agricultural development as an alternative for aid and development effectiveness. On the basis of the theoretical robustness, it conducts a series of analyses to categorize the African recipients by the development stages, incorporating factor analysis, cluster analysis and comparison between the present-future agricultural development levels. The findings propose analysis indicators for phase of agricultural development and clustered results including 18 countries of KAFACI members and priority countries in Africa. In addition to the practical application of the results, the methodological flow can be used as steps for sketching a future roadmap to construct the demand-oriented ODA(Official Development Assistance) plan. This paper also offers implications regarding ODA strategy of Korea in response to the phase of agricultural development and the aid demands.

Fuzzy c-means(FCM)는 퍼지 집합을 응용한 간단하지만 효율적인 클러스터링 방법 중 하나이다. FCM은 여러 응용 분야에서 성공적으로 활용되어 왔지만, 초기화와 잡음에 민감하고 볼록한 형태의 클러스터들만 다룰 수 있는 문제점이 있다. 이 논문에서는 이러한 FCM의 문제점을 해결하기 위해 전역 클러스터링(global clustering) 기법과 커널 클러스터링(kernel clustering) 기법을 결합하여 새로운 비선형 클러스터링 기법인 커널 전역 FCM(kernel global fuzzy c-means, KG-FCM)을 제안한다. 전역 클러스터링은 클러스터링의 초기화를 위한 방법 중 하나로, 순차적으로 클러스터를 하나씩 추가함으로써 초기화에 민감한 FCM의 한계를 극복할 수 있도록 해준다. FCM의 잡음 민감성과 볼록한 클러스터들만 다룰 수 있는 한계를 극복하기 위한 방법은 여러 가지가 있으며 커널 클러스터링이 그 중 하나이다. 커널 클러스터링은 사용하는 커널을 바꿈으로써 쉽게 확장이 가능하므로 이 논문에서는 커널 클러스터링을 사용하였다. 두 방법을 결합함으로써 제안한 방법은 위에서 언급한 문제점들을 해결할 수 있으며, 이는 가상 및 실제 데이터를 이용한 실험 결과를 통해 확인할 수 있다.

추상적 개념을 계량화 하기 위해 상대적으로 구체적인 여러 개의 문항을 조사한 후 이들 점수의 합 또는 이들 점수를 표준화한 후 합을 구하는 리커드 (Likert) 척도 (합산등급척도법)를 많이 사용한다. 합산등급척도법은 각 항목의 크기가 차이가 많이 나는 경우에 원자료가 아닌 표준화 값을 사용하여 합하기도 한다. 이와 같은 상황은 평가 시스템에서도 발생한다. 예를 들어 기초지방자치단체들을 발전정도에 따라 분류하기 위해 인구, 세수현황 등의 값을 표준화하고 이를 단순합산하여 분류의 기초로 사용할 수 있다. 본 연구에서는 위의 같은 추상적 개념의 수치화 또는 평가 시스템에 많이 적용되는 합산등급척도법의 문제점을 개선하는 한 방법으로 가중치를 자료에서 계산하는 데이터 구동 방식의 평가 시스템을 제안하고, 이 시스템을 실자료에 적용한다.

The present study was conducted to analyze high school students' attitudes toward jean brand counterfeits relative to their self-esteem and self-consciousness. The study was implemented through a normative-descriptive survey using questionnaire. The sample consisted of 605 high school students from 6 high schools located in Seoul. Data were analyzed by mean, cluster analysis, regression, ANOVA and Duncan's test. The results were as follows: (1) As a whole, the mean values of preference and purchasing intentions toward counterfeit jeans were 2.99 and 2.83, respectively, indicating a slightly low average on the 5-point Likert scale. The results indicated that 45.5% of respondents have more than one item of counterfeit jeans. (2) Differences were found in the level of self-esteem and public self-consciousness among the three groups, who were classified by the level of purchasing intention and preference toward counterfeit jeans. Among the three groups (high/middle/low), the group having low purchasing intention and preference toward counterfeit jeans showed higher self-esteem and public self-consciousness than the other two groups. (3)Regression analysis showed that the self-esteem and public self-consciousness of high school students have an impact on the amount of purchasing of counterfeit jeans. (4)In the process of developing effective policies against the jean brand counterfeits market, it should be fully considered that high school students' purchasing intentions regarding jean brand counterfeits are related to their self-consciousness. It could be said that the policies followed to eliminate counterfeits and to enhance the consumer ethics of high school students will be more effective when those policies are accompanied by efforts to form their sound self-consciousness, especially in the areas of self-esteem and public self-consciousness.

Matusoka & Kawara (2010) showed that the number density of the most massive galaxies (log $M/M_{\odot}=11.5-12.0$) increases faster than that of the next massive group (log $M/M_{\odot}=11.0-11.5$) during 0 < z < 1. This appears to be in contradiction to another important empirical concept of "downsizing". We attempt to understand the two observational findings in the context of the hierarchical merger paradigm using semi-analytic techniques. Our models closely reproduce the result of Matusoka & Kawara (2010). Downsizing can also be understood as larger galaxies have on average smaller assembly ages but larger stellar ages. Our fiducial models further reveal the details on the history of stellar mass growth of massive galaxies. The most massive galaxies (log $M/M_{\odot}=11.5-12.0$ at z=0), which are mostly brightest cluster galaxies, obtain roughly 70% of their stellar components via merger accretion. The role of merger accretion monotonically declines with galaxy mass: 45% for log $M/M_{\odot}=11.0-11.5$ and 20% for log $M/M_{\odot}=10.5-11.0$ at z = 0. The specific accreted stellar mass rates via galaxy mergers decline very slowly during the whole redshift range, while the specific star formation rates sharply decrease with time. In the case of the most massive galaxies, merger accretion becomes the most important channel for the stellar mass growth at z ~ 2. On the other hand, in-situ star formation is always the dominant channel in the $L_*$ galaxies.

Objectives : Saam acupuncture initiated by Saamdoin is traditional and originative method, which is characterized by applying the five phases theory and mother-child reinforcement-reduction principle to the selection of acupoints and needling manipulation. Our study was aimed to summarize and assess the use of acupoint SP3(Taebaek) in Saam acupuncture treatment and to further understand Saam acupuncture in an aspect of the combination of acupoints. Methods : We searched the data based on "(Do Hae Kyo Kam) Sa-Ahm's acupuncture method" for SP3 used and acupoint combination including SP3. We performed frequency analysis, network analysis, and cluster analysis for quantitative aspect. To understand clinical implication of SP3 with another acupoint, qualitative and descriptive methods were also carried out. Results and Conclusions : In our study, SP3 was frequently used for tonification of lung, spleen, heart, and kidney meridian and sedation of kidney, heart, and lung meridian. For this, many acupoints such as LU8, LU9, KI3, HT8, KI7, LU10 and LR1 were used with SP3. The combination of SP3 and other acupoints were used to treat stroke, common cold, and pain conditions including headache, low back pain, respiratory disease as well as gastroenteric troubles including stomachache, indigestion, vomiting, and constipation. To further understand Saam acupuncture, an understanding of the five transport points based on five elements characters, pathological changes (deficiency and excess) of viscera and bowels, and concept of source point should be preceded.

The purpose of this study was to investigate the trends of product design for textile convergence wearable smart textile fashion products according to college students' fashion life style. In this study, we used information obtained from a questionnaire issued to 201 female college students who were 20 years old for the final analysis. The questionnaires were to classify female college students groups according to the fashion life style, to examine characteristics, needs and wants of each group. The survey on the tendency of wearable smart textiles consisted of 22 items about concept and type of smart clothing product, functional material and intelligent material, recognition, preference, purchase intention, purchase factor and brand preference tendency. A total of 201 samples were analyzed by factor analysis, cluster analysis, ANOVA, crosstabs and $x^2-test$ using SPSS package program. 'brand preference oriented type was found to be interested in 'wearable' smart clothing product with monitoring function of bio-signal' and 'high functional fiber and textile product', but the credibility of 'smart clothes that can be worn and smart textile products to be useful in modern life' was low. 'fashionable individuality oriented' type showed interest in 'smart clothing and smart product', 'intelligent fiber' and 'wearable smart clothing product with monitoring function of bio-signal', but the preferences of 'light emitting fiber products' was low. 'practically purchasing-oriented' type was very interested in 'high-functional fiber and its textile products', but had inadequate knowledge on 'smart clothing and smart textile product' and showed low interest. Despite the fact that 'wearable smart clothing and smart textile products' are expensive, they were willing to purchase considering practicality and sophisticated style.
