  • Ryff's(1989) psychological well-being measure is used to assess and sometimes compare Korean and American adults, however, there is no information regarding whether its dimensions are psychometrically invariant across, whether its items provide sufficient information for, and whether each item measures identical trait levels in, the two nations. Confirmatory factor analysis on response 1,696 Korean and 3,669 American adults, gave to the measure revealed lack of fit and absence of factorial invariance across the two nations. Item response theory revealed significant variance for items on each factor across two countries that most items yielded limited psychometric information. And that each item measure different trait levels, suggesting that in its present form, the measure might lead to misleading results for, and across the two nations.

  • Collaborative filtering, among other recommender systems, has been known as the most successful recommendation technique. However, it requires the user-item rating data, which may not be easily available. As an alternative, some collaborative filtering algorithms have been developed recently by utilizing the market basket data in the form of the binary user-item matrix. Viewing the recommendation scheme as a two-class classification problem, we proposed a new collaborative filtering scheme using a regularized discriminant analysis applied to the binary user-item data. The proposed discriminant model was built in terms of the major principal components and was used for predicting the probability of purchasing a particular item by an active user. The proposed scheme was illustrated with two modified real data sets and its performance was compared with the existing user-based approach in terms of the recommendation precision.

  • The objective of this study is to present basic data for producing tools to measure Yangseng of the elderly aged older than 65 by reassessing the validity and reliability of such tools already developed. In the present study, total 855 subjects were divided into 4 groups and given 31 question for the ultimate factor analysis of each item. The results cloud be summarized as follows: 1. In case of 'don't have sex in drunken state or right after dinner'(the 31st item of sex live yangseng). factor loading came out proportionally in 3 factors such as factor 4=0.358, factor 5=0.389 and factor 6=0.386. As they all failed to reach the general standard of 0.5 or more and even the minimum standard of 0.4 or more, the 31st item was deleted from the questionnaires. 2. From the factor analysis after exclusion of the 31st item, factor loading of the 25th item of sleep yangseng 'go to bed and get up regularly' appeared to be proportional in 2 factor(factor 4=0.393 and factor 7=0.373). Since it was shown that the 25th item could not be classified into a category but interacted with others in common and didn't satisfy the minimum standard of 0.4, it was deleted form the questionnaires, too. 3. From the factor analysis conducted after excluding the item numbers 31 and 25, factor loading of the 12th item of diet yangseng 'do not eat much' turned out to be relatively high with such values as factor 5=0.518 and factor 3=0.453. As it was, however, tied up with the factor of exercise yangseng, it was also deleted. In conclusion, 28 items after excluding the item numbers 12, 25 and 31 form 4 group showed the same results as divided into 8 factor with high grade of reliability and validity, evidencing the assumption that they can be employed practically to measure yangseng of the elderly aged 65 and oder.

  • MPEG-21 is an on-progress project of the Moving Picture Expert Group (MPEG) that has been started in many independent parts such as part for standardizing the declaration of a digital item (MPEG-21 Part 2: Digital Item Declaration), right expression language (MPEG-21 Part S: Rights Expression Language), way to process the digital item (MPEG-21 Part 10: Digital Item Processing), etc. All this part is intended to form a framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices (1). In this paper, we show our research initiative to develop a web-based application that utilized many parts of MPEG-21 technology. The implemented concept uses a digital item and license providers in the server side while the MPEG-21 Conformant application is implemented as a plug-in application that will be downloaded to the user terminal when user accesses the webpage for the frist time. The result of this research shows that with some combination of MPEG-21 parts, we can develop an authorized multimedia delivery and consumption application.

  • 본 연구는 미국의 블리자드社의 FPS 장르 게임 Overwatch의 루트 박스(Loot Box)의 구조를 탐구한다. 현재 최근 게임 산업 가장 큰 논란거리 중 하나는 게임 유저들이 고성능의 게임 아이템을 복권 형식으로 구입하는 "확률형 아이템"이다. 본 연구는 확률형 아이템과 비슷한 해외의 루트박스 사례를 다각적으로 탐구하여, 어떠한 구조를 지니고 있는지를 분석하고 법적인 해석을 시도한다. 이를 통해, 루트 박스 시스템의 장단점을 분석할 뿐만 아니라 국내의 확률형 아이템 문제를 위한 시사점을 제공한다.

  • 건설 가설재 성능검정제도의 전환기에 들어서 주요 가설재들의 성능검정을 평가하고 선진국의 관련 체계와 비교하여, 안전인증제를 통해 새로운 건설공사용 가설재들의 인증제도를 제안하고자 한다. 현재의 성능검정제도는 1992년에 시작되어 2003년에 재 개정되면서, 3년마다 재 검정을 받도록 하고 있다. 그러나 제조능력을 향상시키지 못하고 업체 간 가격경쟁의 심화로 인해 대부분 같은 형태, 기능의 제품만을 양산하고 있는 실정이다. 기존 성능검정제도에서 안전인증제로의 전환은 보다 체계적인 심사방법 및 품질관리 시스템을 포함하고 있으며, 건설 환경 변화에 대응할 수 있는 다양한 요구사항에 맞춘 규격을 제시할 수 있도록 하고 있다. 안전인증제를 통한 건설공사의 가설재는 의무인증대상과 임의인증대상으로 나누어지며, 종전보다 제품의 품질과 관리 시스템을 향상시켜줄 수 있을 것으로 기대된다.
