Recently, feasible services in ubiquitous computing environment are commonly based on context -aware computing. With the concept of context-awareness we can imagine more effective way to measure human being's daily stress and provide anti-stress services. Our study introduces logical and methodological approach to manage the stress through the development of stress index. From the practical perspectives, we also designed a business model for u-SMC, which is a profitable organization specialized in providing stress measurement services and personalized anti-stress services by utilizing the stress index model.

This study was designed to present the direction of Korean K-beauty by examining awareness, selection attributes, and satisfaction of the Chinese on Korean brand mask packs, which currently rank among the top 10 mask packs in China's beauty market. As a result, the perception of Korean Wave, especially entertainment / music preference, has a positive (+) effect on Korean mask pack choice attributes. Also, it was found that the influence of the Korean Wave greatly affected both satisfaction and repurchase intention. The increase of Chinese women's consumption and the appearance of the society due to the advancement of the society also affects the appearance. However, the safety and efficacy of the product has yet to be established. If the improvement of these technologies and the countermeasures of domestic cosmetics companies are provided, Korea's K-Beauty industry will be more active in the domestic and overseas markets.

This study is to analyze the selection criteria for street dance institutes in the subjects of ordinary people and students majoring in street dance who select the institutes. Moreover, it aims to enhance the perception and values of street dance and to provide with the required data for the development of institutes that train street dance. To do so, a survey was conducted in the subjects of 300 street dance learners who went to the street dance institutes. Frequency analysis, reliability test, correlation analysis, and one-way analysis of variance (ANOVA) were performed using SPSS 18.0 Program with the collected data, and the results are as follows. In summary, training programs, services, and promotional environment were identified to be important criteria to select the street dance institutes by the learners while the low level of perception on the price was found.

In this paper we consider Internet Protocol Tele-Vision (IPTV) Service that started recently in Korea. IPTV makes it possible to watch high quality TV programs and a lot of multimedia contents with TV by way of Internet. The service providers are interested in the factors that influence the diffusion of new service such as IPTV. We therefore search the functional-attribute that would influence the acceptance of IPTV service, and propose a model for analyzing the relationship between the attributes and the intention of buying. The model is based on the extended Technology Acceptance Model (TAM). Survey results show that the significant functional attributes influencing the intention of buying are contents variety and convenience.

In the pattern classification problem, feature selection is an important technique to improve performance of the classifiers. Particularly, in the case of classifying with a large number of features or variables, the accuracy of the classifier can be improved by using the relevant feature subset to remove the irrelevant, redundant, or noisy data. In this paper we propose a feature selection method using genetic algorithm and information theory. Experimental results show that this method can achieve better performance for pattern recognition problems than conventional ones.

본 연구팀은 유비쿼터스 게임 플랫폼을 위한 Embedded C++ 컴파일러를 개발하였으며, 컴파일러 개발 과정에서 객체지향언어인 C++과 Java 언어를 모두 수용할 수 있는 심벌 테이블을 설계하였다. 심벌 테이블은 컴파일러의 어휘 분석과 구문 분석 과정을 거친 후 SDT(syntax-directed translation)에 의해 생성된 AST(Abstract Syntax Tree)를 분석하여 인식된 명칭(identifier)과 그 속성(attribute)들을 수집하여 저장하는 자료구조로써, 심벌 테이블에 저장된 속성들은 의미 분석(semantic analysis) 단계에서 수집된 속성과 참조된 명칭의 사용이 타당한지를 검사하고, 코드 생성(code generation) 단계에서 올바른 코드가 생성되도록 하는 중요한 요소이다. 따라서 심벌 테이블의 설계가 올바른지와 입력된 속성이 정확한지에 대한 검증과 분석은 필수 불가결하다. 본 논문에서는 컴파일러 개발과정에서 설계한 심벌 테이블을 검증하고 분석하기 위한 목적으로써 심벌 테이블을 이용하여 선언문을 복원시키는 역번역기(detranslator)에 대하여 기술한다. 구현된 역번역기는 C++ 컴파일러와 Java 컴파일러의 선언문 처리 과정에서 심벌 테이블에 입력된 속성들을 본래의 입력 프로그램으로 역번역한다. 따라서 역번역기를 통하여 심벌 테이블의 완전성과 심벌 테이블에 입력된 속성 정보의 정확성을 쉽게 검증할 수 있으며, 역번역과 함께 출력되는 디버그 정보를 이용하여 효율적으로 컴파일러의 개발과 수정을 할 수 있다.

The purpose of this study is to establish a marketing strategy for the makgeolli manufacturing industry. We fractionized cousumer types depending on motives for purchase of customers who had bought makeolli or drunk it for the last six months. We also examined the relationship between makgeolli selection attributes and customer satisfaction by the cousumer types. SPSS 15.0 statistical package was used to process data. Frequency analysis, factor analysis, a reliability test, K-means cluster analysis, one-way ANOVA, and multiple regression were executed. As a result, the motives to purchase and drink were divided into four factors - marketing, effect on health, self-desires, outside environment; consumers into three types - dependent type, loving type, indifferent type; makgeolli selection attributes into five factors - health characteristics, visual elements, brand characteristics, drinking characteristics, purchase characteristics. It was shown that the makgeolli loving type considered all the makgeolli selection attributes as most important; the dependent type considered the health characteristics and visual elements as less important than the loving type did. The indifferent type considered all the makgeolli selection attributes as less important compared with the other types. Among the makgeolli selection attributes, drinking characteristics and the purchase characteristics had effects on customer satisfaction.
