With the advent of smart devices, users are able to connect to each other through the Internet without the constraints of time and space. Because the Internet has become increasingly important to users in their everyday lives, reliance on it has grown. As a result, the number of web sites constantly increases and the competition between these sites becomes more intense. Even those sites that operate successfully struggle to establish new strategies for customer retention and customer development in order to survive. Many companies use various customer information in order to establish marketing strategies based on customer group segmentation A method commonly used to determine the customer groups of individual sites is to infer customer characteristics based on the customers' demographic information. However, such information cannot sufficiently represent the real characteristics of customers. For example, users who have similar demographic characteristics could nonetheless have different interests and, therefore, different buying needs. Hence, in this study, customers' interests are first identified through an analysis of their Internet news inquiry records. This information is then integrated in order to identify each web category. The study then analyzes the possibilities for the practical use of the proposed methodology through its application to actual Internet news inquiry records and web site browsing histories.

Purpose: The purpose of this study was to understand and describe the experiences of exercise maintenance in elderly with osteoarthritis (OA). Methods: Three focus group interviews were conducted with a total of 19 older adults with OA who have been exercising for more than six months. Results: Two main themes emerged from the analysis: the changing exercise in life's journey (exercise maintained by self and family affection, exercise maintained by social networking expansion, exercise changing for function and body-image and exercise changing for economic efficiency) and the exercise pervaded into the life (Exercise used as a side effect-free treatment, exercise internalized by will and a sense of accomplishment and exercise become daily routine habits). Conclusion: Despite the various problems associated with aging and OA, participants made exercise a part of their lives by changing it to fit their own functions, abilities and circumstances. It is necessary to emphasize the positive aspects of the overall situation and to provide appropriate education and exercise based on the theory as well as the individual's overall fitness and limitations.

Korean population is now aging at an unprecedented rate. Fertility decline together with rapid improvements in life expectancy is the dominant demographic trend. As human life and housing environment are inseparably related to each other, the importance of conditions of housing environment for active aging among seniors has been received considerable attention as vital ones to expand the independency period of seniors. The purpose of this case study is to identify relationships between environmental affordance and perceived holistic health of the active elderly living in a retirement community located in Seoul. With spending time personally in the community to observe their lives, the researcher could be in close rapport with the residents. After the period of getting familiar with each other, in-depth individual interview and focus group interview were conducted and then, qualitative analysis was completed. As a result, general evidences showed that perceived seniors' health on the whole was improved physically, socially, and mentally by moving into the community providing appropriate environment affordance with the older adults. The study presents that retirement relocation into an improper environment may be a negative challenge, however, it may positively influence on the health and well-being of those who live there if the environment properly supports seniors‘ needs physically and socially

For the reduction of flood damage, it is necessary to analyse shelter activities of local residents and to publish information of floodings, In this paper the control factors of individual refuge activities which are major activities to save peoples lives against floodings have been estimated. Decision making factors for mental refuge activity by the questionnaire survey were classified into two categories: internal and external ones. Furthermore, the behaviour patterns of residents for flood risk related to geographical and social factors were derived by the quantification method n. Since spatial layered information using GIS were corrected and estimated to serve citizen's consensus due to flood disaster, it would aid reduction and minimization of flood risk.d risk.

SNS(Social Network Services) is being recognized as an important part in our society, individual lives and corporate business aspects, and the influence of SNS is growing explosively as expansion and supply of infrastructures that support mobile environments increase. Previous studies related to SNS were focused on user acceptance of new technology, based on Technology Acceptance Model(TAM). However, they had a limitation to focus on technology acceptance, without the consideration of personal and behavioral factors in SNS use. However, above all, successful SNS requires the understanding of users who are active on the network. Therefore, from the user's perspective, this study attempted a multi-dimensional approach by reflecting characteristics that come from SNS usage. This study considered user innovation, virtual skill, self-efficacy, social pressure and network effect as independent variables, and perceived ease-of-use, perceived usefulness and perceived value as mediating variables, and intention-to-use as dependent variable. The result showed that user innovation, self-efficacy, social pressure and network effect had a significant effect on the mediating variables. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategy for acquiring and retaining lone-term customers related to SNS business.

The purpose of this study is to investigate factors that explain the degree of need for community welfare services designed for the residents of Wonju City. For this purpose, we identify five categories of community welfare services : employment no income supporting programs, residence supporting programs, public health programs, family programs and welfare facilities for enhancing quality of life. The data come from 234 adults living in Wonju city, Major findings can be summarized as follows. Firstly, we find that participants are well aware of needs for community welfare service, and that the degree of need for public health services is the highest among the five types of welfare programs. Secondly, we find differential effects of the individual factors such as predisposing, enabling, and need, and the community factors such as quality of environmental facilities which make daily lives convenient, and residential region. Particularly, environmental facilities appear to have a strong association with high needs for the majority of welfare services. Finally, differences between urban and rural areas are still observed. These results suggest that the responsibility of Wonju city for providing diverse and adequate welfare services should be emphasized. Priorities for welfare policies based on the empirical data are also taken into consideration in the process of developing community welfare policies.

The primary health care(PHC) movement officially began in 1977 when the 30th World Health Oranization(WHO) Assembly adopted a resolution accepting the goal of attaining a level of health that permitted all citizens of the world to live socially and economically productive lives. As a WHO member nation, Korea has endorsed primary health care as a strategy for achieving the goal of Health For All by the Year 2000. However, PHC, with its empasis on broad strategies, community participation, self reliance, and a multidisciplinary health care delivary team, is not the primary strategy for improving the of Korean. The Neuman's systems model has been described as a grand nursing theory. A grand nursing theory consists of a comprehensive conceptual framework that defines broad perspectives for practice. This model is an example of a conceptual framework that provides structure for development and analysis of an individual or group of patients in the community or in an oranization. One of the model's strength is that it can be useed ina variey of setting. So The Neuman's model is used a nursing process format for community health nursing. The Neuman's model is fully congruent with concept and philosophy of today's PHC.

Space design is a process of solving spatial problems to create and construct all kinds of human lives. It also bestows new values to a medium to induce human perception based on the relationships between 'human and space' surrounding people. Research on user behavior has several ultimate goals including understanding both individual behavior and the relations between the user and space from a more scientific and systematic perspective, predicting various phenomena that can happen between space and humans, and reflecting the results in space design. As user behavior that's once limited within given space is going through some changes due to the introduction of digital technologies, research on user behavior in today's space design should be newly illuminated in the aspects of organic relations. Space now works as a receptor communicating with the user and responding to user behavior, and user behavior once under one-sided influences from space becomes more diverse and active. The influences of user behavior, in turn, cause changes to space itself. Thus this study set out to suggest new directions in research on user behavior based on interactions between space and the user in space design.

This study sought to identify unique semiotic codes of Korean cuisine, including table settings, service styles, service ware selection, cooking techniques, and the logic behind menu composition. This research also aimed to verify that yangnyomjang reflects the code of Korean food culture. One of key findings from this study was that hidden codes of Korean food were found in their daily set-up for bapsang (dining table), which was found to decodify polysemic characteristics with an emphasis on harmony. These semiotic codes were influenced by the yin and yang philosophy and impact dining activities in our daily lives. Korean bapsang, composed of bap (rice), guk (soup) and banchan (side dishes), helps every individual diner share the semiotic codes of Korean cuisine within the context of paradigm and syntagm. Yangnyomjang, a major component of the Korean menu, also represents a unique code of Korean cuisine in its structure, main ingredients, production, and usage. This study also mathematically verified that a synchronic table setting of Korean cuisine provides diners with more opportunities for potential flavor combinations, compared to the Western service setting.
