Context-awareness system can provide an optimized services to users. Analyzing physical and complex circumstance elements which give direct or indirect influence to users can tell what users want. However, there are various situation informations around users and it requires high level technology to extract the service what users really want among those informations. The circumstance of the user can be changed from moment to moment, even the service what users want also can be changed in every minutes. Recently the researches to provide the service which a user demands has been progressed actively. Web based filtering method which reaches commercialization is a one of good examples. This method extracts necessary data according to users' demands from the documents on the Web or multimedia informations. However, there is a limit to use it to provide Context-awareness service because it extracts static data, not dynamic data. There is also other researches with a rule based filtering method in progress to filter situation information but this method doesn't have mechanism for dynamic data as well. We would like to solve these problems by providing a dynamic situation information filtering mechanism applying an weighted value about each property of objects and also applying Web based dynamic categories in this paper when unnecessary data should be filtered.

The study was an exploratory research on the awareness of informatization and attitudes to information technology (IT) and its use among elderly women in a metropolitan area. The questionnaire survey was conducted to collect data on IT use or non-use of elderly women aged 60 or older in senior welfare centers in Seoul, Korea. The data on 343 cases were analysed using SPSS 21.0. As a result, the rate of internet use was relatively high and different according to socio-demographic factors, such as age. The elderly women's attitudes like the levels of awareness and expectation of informatization were positive. Elderly women learned to use IT for psychological, emotional reasons as well as for practical ones, and the satisfaction level of IT use was relatively high. Finally, most IT non-users were indifferent and ignorant about IT use. In addition, the dissatisfaction level of IT non-use was normal, but elderly women had a relatively positive expectation of IT use in the future. This study may contribute to understanding the diverse pictures of IT use and the digital divide in old age, and assist in the development of practical programs and policies for the informatization and welfare for older adults.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level.

This study investigated the awareness and purchase status of the private dental insurance. Self-reported survey was conducted with patients over the age of twenties who visited dental institutions located in Seoul Metropolitan City and Gyeonggi Province. The demographic and health related characteristics of respondents were analyzed, and logistic regression was conducted to examine factors affecting the awareness and purchase of private dental insurance. Because only four years had been passed since the introduction of private dental insurance, the awareness and purchase rate was found to be low. However, the number of people considering subscription due to the economic burden of dental care service was relatively high. Factors affecting awareness were satisfaction of the national health insurance, purchase of private health insurance and private dental insurance, self-perceived dental health status, and smoking. The variables affecting purchase of dental insurance were age, awareness, purchase of private health insurance, smoking, number of visits to dental institution. Because qualitative and quantitative change would be made in the dental care utilization due to the rapidly growing dental insurance subscribers, further studies regarding the trend of purchase rate of private dental insurance and the effect of dental insurance on use of dental institution are needed.
