기업들이 심화된 경쟁체제 속에서 고객에 대한 보다 심층적인 이해를 필요로 하고 정보기술의 발달로 각 요소활동내용의 데이터화가 가능해짐에 따라 CRM으로 대변되는 고객 정보의 전략적 활용이 매우 중요하게 되었다. 이를 위해 기업은 고객에 대한 이해를 바탕으로 고객관리 및 마케팅을 수행하기 위한 필수적인 도구인 고객세분화를 수행하고 있다. 본 연구에서는 신용카드고객의 카드사용행태에 근거하여 서로 유사한 사용행태를 보이는 고객군으로 세분화하는 과정을 소개한다. 고객이 실제로 카드를 사용하면서 발생시킨 거래정보에만 의존하여 고객세분화를 수행하였으며 이는 마케팅의 관점에서 상당히 의미 있는 내용이라 볼 수 있다. 고객세분화를 위하여 데이터마이닝기법인 k-평균군집방법과 최장연결법에 의한 계보적 군집방법을 활용하였다

최근 디지털 컨텐츠의 기하급수적인 증가와 함께 사용자가 접하고 관리해야 하는 파일의 양이 급격히 늘어나고 있으며 이에 따라 폴더의 계층구조가 넓고 깊어지는 현상이 나타나고 있다. 현재 파일시스템은 크게 두 가지 형태로 나누어 볼 수 있는데, 사용자 자신에게 의미 있는(semantic) 계층구조(hierarchical structure)형태의 폴더 내에 파일을 저장하는 방식과 Meta Tag를 사용한 방식이다. 이러한 두 가지 파일시스템을 사용자가 인식하고 Conceptual Model을 형성해 가는 과정에 있어서 사용자의 지리적, 역사적 전통 등의 문화적 요소들이 기저에서 작용하게 된다. 본 연구에서는 각기 다른 문화적 성향을 가지고 있는 사용자 간의 File System을 인식하고 구조화하는데 있어서 차이점이 있을 것이라는 가설을 수립 하였고, 가설을 검증하기 위하여 파일 시스템의 사용 행태를 분류하고, 이러한 행태들이 사용자의 문화적 요소에 따라 어떠한 차이를 보이는지에 대하여 페이퍼 프로토타이핑 등의 기법을 사용하여 실험을 설계 하였다. 또한 이러한 연구모델의 검증을 위하여 파일럿 테스트를 진행하여 실효성 있는 가설검증방법에 대한 모델을 제안하고자 한다.

This research begins from the recognition that the Korean library OPACs have failed in reflecting the information needs of children, and especially the behavioral aspects of digital kids. Maintaining such problem recognition, this research examines the weak points and limits of Korean OPACs for digital kids, and explores the possible solutions. In details, identified at the first hand is digital kids' library use behavior, in particular, their search behavior of library OPACs. Also discussed is on the development of a new generation OPAC for digital kids. The data were collected from a survey with 545 elementary school students, in-depth interviews with 8 carefully selected students among the survey participants, and a direct observation on the children's information search process in 6 libraries.

The purpose of this study was to investigate the relation between health behaviors and asthma among male and female adolescents. The data were derived from the 12th Korea youth risk behavior web-based survey 2016 in Korea. The subjects were 65,528 Korean adolescents. The diagnosis rate of asthma in male adolescents was 10.3% and the diagnosis rate of asthma in female adolescents was 7.8%. In male adolescent, health behaviors that related to diagnosis of asthma were drinking (OR=1.087), second-hand smoke exposure (OR=1.087), non-vigorous physical activity (OR=1.084), obesity (OR=1.291), insufficient sleep time (OR=1.113), and stress (OR=1.257). In female adolescents, health behaviors related to asthma were smoking (OR=1.242), second-hand smoke exposure (OR=1.111), vigorous physical activity (OR=0.899), obesity (OR=1.178), and stress (OR=1.251). The results of this study will be used as basic data to develop a health promotion program of asthma youth according to gender.

This study was carried out for the Centum Shinsegae Department Store, to grasp the indoor rest space and furniture design status, this study analyzes the characteristics of visitors' use behavior centered on furniture. The purpose of this study is to provide basic data for commercial rest space design by understanding the characteristics of resting space in commercial space and whether the furniture can support the behavior of visitors. The research method is to carry out on-site inspection, including the location of the rest space on each floor, the type and design characteristics of the furniture design, and the characteristics and patterns of the users on each were analyzed. The results of the study are as follows. As a result of analyzing the rest space and furniture, the furniture is brown, it has been provided with various designs such as fan-shaped, arched bench, sofa, chair type, and comfortable colors of lightness ranging from light gray to black, and appropriately supported the most common usage patterns.However, in the case of Shinsegae Department Store, it is necessary to consider the safety and convenience of the vulnerable groups.

The purpose of this study was to investigate the effect of diabetes on periodontal disease according to oral health behavior. The date from the 2013-2015 Korean National Health and Nutrition Survey were used, and 14,282 subjects were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index and using logistic regression. When all of the oral health behaviors were included in the model, tooth brushing frequency, flossing, and interdental brushing were significantly associated with periodontal disease, and periodontal disease risk was significantly higher with diabetes, but there was little difference in periodontal disease risk by input factors. Oral health behaviors were associated with periodontal disease in the normal blood glucose group but not in the presence of diabetes mellitus. If there is diabetes, it is difficult to manage periodontal disease by only the health behavior, so it is necessary to control blood sugar.

This study aims to analyze students' information needs and information-seeking behavior at science schools for gifted through in-depth interviews. The research design was conducted based on previous studies. Through in-depth interviews, this study examined ten students from six out of eight science schools for the gifted in Korea for information needs and overall information-seeking behavior. The results showed the information needs of students at science schools for gifted in the areas of curricular and extracurricular activities as well as the information-seeking behavior in teaching, learning, and research activities, which were the main topics of interest to students based on the ISP model. Based on these results, we identified the preferred information sources in the information-seeking process and discussed the peculiarities and implications of students' information-seeking behavior. The research is meaningful as it can be used as a basis for further research on the science school for gifted library and as a resource for providing services for students with deep interests and talents in science subject areas.

The purpose of this study is to investigate the information behavior of the junior high school students in the public library and to find the effectiveness of the behavior analysis using a cognitive work analysis(CWA). Data was collected through a dept interview and an observation method. Results show that the students had four constraints when they searched materials for reports: relevant materials for reports, limitation of materials, opening hours, use possibility. There are three behavior types. A type is that students find materials on the shelf through searching an online catalog, then make a report using reading the materials. B type is that students find materials on the shelf and check out the materials. C type is that students find materials and check out them by library staff help. CWA can be used for the information behavior research on the library space. CWA can, however, apply for space redesign when various researches would be conducted about the information behavior.

Several countries have built National Spatial Data Infrastructure (NSDI) for information sharing among various fields. One of the important factors of NSDI is framework data, which is the most commonly used geospatial data across various fields. Previous studies on the framework data suggest components based on frequency survey and case study. However, such research methods do not have objectivity in setting the components of the framework data. This research uses factor analysis with 104 medium-level layers from the most widely used National Base Map and 5 layers from the other sources including cadastre and aerial image. Each layer is scaled with usage level as four different patterns of 1) background data, 2) reference data, 3) base data, and 4) other data, respectively. The analysis results show that the layers are grouped into 5 to 7 factors according to the patterns. ANOVA reveals that the mean differences between the factors with high values and the other factors with low values under each pattern are statistically significant. Such high value factors under each pattern consist of similar layers, close to identical, with those under the other categories. This research proposes framework data system, including transportation, building, hydrography, elevation, administrative district, digital orthoimagery, geodetic control, and cadastral based on the analysis results. Proposed framework in this research will be a basis of establishing spatial data sharing system. For sharing proposed framework data in various fields, these data must be established and distributed as actual standard and also related future researches should be performed.
