The studies on the human environment and ecosystem analysis is being actively researched. In recent years, The service of genome analysis has been offering the customized service to prevent the disease as reading an individual's genome information. The genome information by analyzing technology is being required accurate and fast analyses of ecosystem-dielectrics due to the spread of the disease, the use of genetically modified organism and the influx of exotic. In this paper the algorithm of K-Mean clustering for a new classification system was utilized. It will provide new dielectrics information as quickly and accurately for many biologists.

This study empirically studied the factors affecting the intensity of use of mobile social media and fatigue. Theories for the research framework were based on the theory of planned behavior, the theory of private information protection, the theory of flow, and the theory of process incentives. As a result of data analysis, it was found that self-efficacy, user habits, and flow experience positively influence the intensity of mobile social media use. This study assumed that personal information protection issues negatively affect the intensity of mobile social media use, but have little influence on the use intensity. The intensity of media use had a positive effect on media fatigue. In other words, when the intensity of using mobile social media increased, the feeling of fatigue increased. The expected process incentives variable did not show a moderating effect between media use intensity and social media fatigue. The findings will have implications for social media-related companies and organizations that want to use social media tools for business and public services.

The study explored the key factors(content satisfaction factor, functional satisfaction factor, inertia factor and situational factor) that influence OTT users' continued use from the perspective of Behavioral Economics. In addition to rational factors that make OTT users feel satisfied after experiencing the contents and functions by the platform, we assumed that it would also affect habitual factors from the 'status quo bias'. To verify this, an online survey was conducted on 523 adults in 20s and 40s who have subscribed to the Top3 OTT platform(Netflix, Wavve, and Tving). As a result of regression analysis, 'content satisfaction factor', 'functional satisfaction factor' and 'inertia factor' were significant in OTT continued use. 'Inertia factor' did not affect domestic OTT users. Unlike previous studies that supposed OTT service users as beings with complete rationality, this study is meaningful to explain OTT continued use by applying 'bounded rationality'.

최근에 우리 사회는 불규칙적인 식습관, 부족한 운동, 과도한 스트레스 등으로 만성질환 및 성인병 환자가 늘어나는 심각성이 날로 커지고 있다. 성인병의 심각성은 40대 이상에서 크게 대두 되었던 과거와 달리, 최근에는 20대를 넘어서서 10대 청소년에게까지 성인병을 앓고 있는 환자들이 날로 많아지고 있다. 세계적으로 IT가 크게 발달함에 따라 병원과 환자가 서로 만나지 않아도 24시간 소통이 되는 u-Healthcare 시스템이 크게 대두되고 있다. 이에 따라서 환자 개개인과 주치의가 시 공간에 제약받지 않고 상호 긴밀하게 진료, 검사 및 피드백이 가능하게 된다. 본 연구진은 u-Healthcare 시스템에 부합하고 스마트 폰을 이용하여 만성질환자를 관리할 수 있는 u-DailyCare 시스템을 설계하고 구현하였다. 스마트 폰 사용자로부터 얻어진 생체 정보 데이터 및 행위 데이터들을 수집하여 서버에 보내면, 주치의는 종합된 전체적인 데이터를 실시간으로 확인하여 환자의 상태를 검토 및 진단하여 피드백을 준다. 본 논문에서는 u-DailyCare 시스템의 설계 및 구현과정을 설명할 것이다.

Electronic books offer various possibilities for expanding access as well as changing reading behavior in our life. However despite the considerable promise of e-book, e-book market was not vitalized than re expected. This study investigated the current e-book environment and suggest some guidelines for making e-books a viable part of libraries' collections and our reading life. Findings and issues about the status of the current e-book market and technologies, and some experience of libraries in the advanced countries give us a lesson for the Korean library societies.

This is a methodological study designed to develop a comprehensive geriatric assessment package for successful aging of the elderly in various health condition. Assessment items and tools were primarily selected and categorized into 9 domains through the review of existing geriatric assessment tools, which have been used in the clinic and community settings, and the investigation of related articles. We have obtained professional advice from three experts and conducted a preliminary survey (n=15). Based on findings, the final version of comprehensive geriatric assessment package were devised. It was constructed of 29 assessment items in 6 domains of basic, psychologic function, physical function, life style, subjective health state, and environment. It also contained concrete implementation guide of each tool.

본 논문에서는 압력 온도 센서를 이용하여 수면자의 수면상태를 인식하고 이를 감지할 수 있는 수면상태 감지 시스템을 제안하였다. 기존의 수면상태를 측정하는 방법에 있어 문제점으로 들 수 있는 고가의 장비, 측정의 불편 등을 해소하기 위해 사용이 간단한 Straingage 타입의 압력센서와 프로브 타입의 온도센서를 이용하여 저비용의 효율적인 시스템을 구현 하였고, 수면 매트에 실세 적용하여 그 유효성을 평가하였다. 제안된 시스템은 압력 온도센서를 이용해 수면 매트부, 센싱데이터를 감지 수집하여 수신된 데이터를 증폭하는 수면상태 감지정보 시스템부로 구성되었다. 시스템 구축을 위해 먼저, 수면 매트부는 비접촉 방식의 압력 온도 센서를 사용하였고, 수면상태 감지정보 시스템부는 미세한 변화를 보이는 데이터를 차등 증폭기 원리를 이용하여 증폭하였다. 센서가 수면자에 의해 변환할 때 발생되는 아날로그 신호를 검출 증폭한 후 감지하는 시스템이다. 본 연구에서 세안한 수면상태 감지 시스템을 이용하여 개인생환 습관인 수면시간을 실시간으로 감지하고 데이터화하여 수면자의 수면 상태를 파악하여 건강한 수면을 위한 방법을 권고할 수 있다. 향후 감지된 데이터를 이용해 실시간으로 가족들의 수면상태를 알릴 수 있는 헬스케어 모바일 응용 서비스로도 활용이 기대된다.

본 논문에서는 키넥트와 압력센서를 이용하여 수면자의 수면자세를 인식할 수 있는 수면자세 모니터링 시스템을 제안하였다. 기존 수면 모니터링 시스템은 장시간 착용해야 하는 불편함과 구속감으로 인해 수면의 질을 저하시킬 우려가 있다. 이러한 점을 해소하기 위해 압력센서와 키넥트 카메라를 이용하여 무구속 저비용의 효율적인 시스템을 구현하였고, 수면 매트형식으로 제작하여 그 유효성을 평가하였다. 본 연구에서 제안한 수면자세 모니터링 시스템은 실시간으로 수면자세를 감지하고 사용자의 수면시간 및 상태를 파악하여 건강한 수면습관을 들이는 방법을 권고할 수 있다. 향후에는 수집된 데이터를 이용하여 웰니스 및 헬스케어 모바일 응용 서비스로의 활용이 가능할 것이다.

The objectives of this study were to explore food-related lifestyle segments of the older consumers, to identify its socio-demographic characteristics, and to investigate the differences in variables regarding health beliefs. A survey was conducted of adults 55 years of age and older living in Seoul, South Korea from March 28 to April 10, 2007. Out of the 500 distributed questionnaires, 361 were retained for final analysis: a response rate of 72.2%. As a result of cluster analysis, five consumer segments were identified; health-managing group, diet-unconcerned group, convenience-oriented group, taste-oriented group, unpracticed group. Significant differences were found among the five segments in terms of socio-demographic characteristics and variables regarding health beliefs (i.e., perceived self-efficacy, perceived barriers, perceived benefits). In the health-managing group and taste-oriented group, mean scores of perceived self-efficacy (p<0.001) and perceived benefits (p<0.001) were significantly higher than other groups. However, in the diet-unconcerned group and convenience-oriented group, the mean scores of perceived barriers (p<0.01) were significantly high. This study shows that foodservice operators targeting the older consumers should consider characteristics of each segment to develop a customized program.

This study was to evaluate health management and life habits of the urban salaried workers. The results showed the followings: There were more men than women who thought their health good (p<0.01). Stomach disease was the highest in the subjects, and the second was liver disease (p<0.001). Of respondents, 10% always exercised in the morning, 26% often, and 63% never. Men took exercise more regularly than women (p<0.001). The kinds of exercises were walk (33%), jogging (25%), physical training (14%), golf (6.4%), rope jumping, and tennis. Men ate healthy drug more than womon. Most of men thought that sports were the best for health management. Women considered that baying regular habits was the best for control of her health. The smoking rate of respondents was 41%, and the rate in Chinju showed higher than the other area (p<0.001). Man smokers were more than women (p<0.001). Drinking rate of respondents was 78%.
