  • Constructing the national inventory that can be used as a tool to identify and assess existing or potential contamination is necessary for efficiently managing the soil and groundwater contamination. In order to start this construction, the first step is how we define and classify potential contamination sources of soil and groundwater. After selecting the basic classification model of contamination sources from developed countries, we suggested the classification and list of the potential contamination sources of soil and groundwater which are appropriate for specific conditions of South Korea. In addition, we investigated several databases to confirm the existence of available data sources and then examined established attribute data through chemical accident response information system (CARIS) and water information system (WIS) in National Institute of Environmental Research and mine geographic information system (MGIS) in Mine Reclamation Corporation. All sorts of attribute data in the existing databases can be utilized as significant assessment factors for determining the management priority of potential contamination sources in the future. Therefore, it is required the expanded investigation of additional database sources and the continual modification so that the classification system of potential contamination sources can be improved.

  • Using data from the 2007 SCF, this study examined the use of information source for investment decisions of elderly consumers. The results indicated that many elderly consumers (about 88%) involved savings /investment decisions. The elderly used 'Experts' (39.48%) as a major information source for their investment decisions, followed by 'Friends' (24.18%). The results of the multinomial logit analysis suggested that the perceived value, the cost for search, knowledge, risk and some of the demographic factors were significantly related to the choice of the information sources for investments by elderly consumers.

  • In Korea, recent trends indicate an increase in the volume of the functional clothing market. This study investigated the evaluative criteria and information sources of functional clothing according to gender and age. A total of 756 responses were analyzed using descriptive statistics, MANOVA, and Duncan's test. The main effect of gender on the evaluative criteria and information sources of functional clothing was identified. Compared with male consumers, female consumers gave more importance to price and aesthetic criteria. Female consumers take advice from colleagues and companions, as well as use information obtained from mass media to a greater extent than male consumers. Age was seen to have an effect on evaluative criteria and information sources in purchasing functional clothing. Respondents in their forties and fifties took textile quality and durability more seriously. Information available on the Internet and following the dressing styles of celebrities were preferred by respondents in their twenties.

  • 현대 암호 시스템과 암호모듈의 필수적 요소인 난수발생기의 안전성을 평가하는 방법으로 잡음원에 대한 엔트로피 평가 방법이 있다. 국외 주요 엔트로피 평가 방법은 소프트웨어 잡음원보다 하드웨어 잡음원에 적용하는 것이 더 적합하고, 소프트웨어 잡음원별 엔트로피에 대한 정량적인 평가의 어려움이 있다. 본 논문에서는 소프트웨어 잡음원의 특징을 고려하여 소프트웨어 잡음원에 적합한 엔트로피 평가 방법을 제안하고자 한다. 윈도우 운영체제의 소프트웨어 잡음원 중에서 시간 종속 잡음원을 분석 대상으로 선정하고, 각 잡음원의 특성을 고려하여 휴리스틱(heuristic) 분석과 실험적 분석을 진행한다. 이를 기반으로 하여 시간 종속 잡음원에 대한 엔트로피 평가 방법으로 잡음원 수집 방법과 최소 엔트로피 추정 방법을 제안한다. 그리고 미국 NIST의 SP 800-90B에 기술된 Conditioning Component에 제안하는 평가 방법을 활용하는 방법을 제시한다.

  • This study was inspired by the growing importance of information as a resource for improving the quality of life, the lack of systematic research about the information environment of Koreans in the United States and the lack of understanding of the relationships between individual characteristics and information seeking behavior. During 1990 and 1991, 204 Koreans, 18 years old and more, residing in the City of Los Angeles, were interviewed. Generally the information seeking behavior of Koreans appeared to be similar to that of the socioeconomically advantaged segment of the general public. They are relatively well aware of their information needs. capable of articulating them, and willing to pursue information to meet their needs. Major findings include: (1) the dominance of educational information needs: (2) positive feelings of hope, curiosity. and interest associated with information needs: (3) the tendency to pursue information with the expectation of potential rather than immediate rewards: (4) the expertise of information sources and their ability to provide information directly relevant to a need as criteria for selecting an information source: (5) the generally heavy reliance on informal interpersonal information sources and the high ranking of professionals as the starting point for information seeking and in judgements of usefulness: and (6) the dominant use of Korean ethnic information sources. Statistically significant correlations found at the 0.05 level relate (1) level of education, age, and gender with type of information need, the feelings associated with an information need, motivations to seek information, and the use of information sources, (2) proficiency in English and length of residence in the United States with the extent to which ethnic information sources are used, and (3) pattern of daily use of media with the use of media in seeking information.

Research design, data, and methodology - 125 Islamic bank customers and 125 conventional bank customers were surveyed. The study employed two independent sample tests. Additionally, an exploratory study was conducted to support the quantitative analysis. Result - The results show that Islamic bank customers use personal as well as marketing information sources more intensely than conventional bank customers, although the result differences were not significant. Specifically, customers of Islamic banks use certain personal resources (parents and friends) and marketing information (marketers)intensely than conventional bank customers. Conclusion - The study revealed that friends and parents are the most important information sources for the selection of the Islamic bank. In addition, based on the resources used, Islamic banking customers can be classified as traditional and religious communities. Therefore, the most effective customer communications will be through Islamic groups such as Islamic social institutions and Islamic educational institutions.
