Smartphone is affecting not only our everyday life but also our business, directly causing diverse side-effects. But up until now, many researches that have been conducted on smartphone were focused on continuance intention for smartphone use and user satisfaction. Thus, the objective of this research is to investigate the effects that smartphone dependency has on digital dementia which is one of negative effects of smartphone. For the purpose, we have reviewed studies that are related to perceived characteristics of existing smartphones. As perceived characteristics variables, we have adopted perceived ease of use and perceived usefulness. And to present our research model, we have adopted smartphone dependency as psychological attitude variable and digital dementia as consequence variable. To implement an empirical analysis of our research model, we have conducted a survey with college student groups as research target who use smartphone most.

Conventional filters using email header and body information equally judge whether an incoming email is spam or not. However this is unrealistic in everyday life because each person has different criteria to judge what is spam or not. To resolve this problem, we consider user preference information as well as email category information derived from the email content. In this paper, we have developed a personalized anti-spam system using ontologies constructed from rules derived in a data mining process. The reason why traditional content-based filters are not applicable to the proposed experimental situation is described. In also, several experiments constructing classifiers to decide email category and comparing classification rule learners are performed. Especially, an ID3 decision tree algorithm improved the overall accuracy around 17% compared to a conventional SVM text miner on the decision of email category. Some discussions about the axioms generated from the experimental dataset are given too.

This study is aimed to evaluate the effects of the educational program that is designed to help the patients of T.K.R.A. to improve their self-nursing ability. The research will show how well this program can contribute to raising of their adaptability of everyday life by decreasing the difficulties that the patients had before in their daily life. The sample persons for this research were 40 adult patients who had T.K.R.A. in our hospital, and the data were collected through the questionnaires which were given to them. For the surveying tool, Jette's scale was applied to measure the degree of uncomforting that the patients experienced in their daily life. The materials of report had been gathered from May 1st to December 10th. The collected data were analyzed with real numbers, percentage, average, the standard deviation, TorF test and Pearsons correlation. The results of this study can be summarized like follows: The survey of self-caring exercise part were processed with two groups containing experiment group and contrast group. The exercise which took the highest points in experiment group was repetition of stretching and bending knees with laid down position while taking a walk, repetition of stretching and bending knees with seated on chair position and repetition of stretching and bending knees with laid down position got high points in contrast group. There were distinctive differences in statistics between repetition of stretching and bending knees in laid down position and taking a walk. There was no significant statistical gap between the degrees of inconveniences of daily life that each two groups experienced when we compared the average of the two groups, but 12 out of 20 questions got considerable differences. According to common characters of self-caring, there was a distinctive gap in the group who left the hospital in 14days and the ones who spend more than 30 minutes with exercise. The patient group who left the hospital in fourteen days after T.K.R.A. spent more time doing self-caring exercise. In the relationship between common characters and the degree of difficulties of daily life, Exercising is effective and Spending more that 30 minutes for exercise showed visible differences. The patients who answered that exercise are effective and put more time for it experienced less pain in their everyday life. The data proved by Pearson's correlation showed the relationship between self- caring and the degree of pain of daily life. According to the result, the increasing of self-caring activities helped to down the degree of inconveniences of daily life. This data show that T.K.R.A. reduced self-caring exercise ability and daily life activities. Therefore, the medical staffs who would take care the T.K.R.A. patients should offer stable nursing through well scheduled and education materials for patients. It is also important to encourage the patients to participate to the exercise by showing them how exercise after T.K.R.A. The education program is expecting to guarantee not only the right of patients to get enough information but also effective result to decrease uncomfortable of daily life.

Citizens' demand, which has been previously focused on welfare, is now expanding to include elements for higher quality of life such as employment, housing, culture, and sports. Accordingly, the government, with an aim of effectively delivering resident services that satisfy various demands, is committed to transforming the central government-oriented service system into the integrated service system based on public-private partnership. The government is also dedicated to expanding services to 8 areas including not only welfare but also healthcare, employment, housing, education, sports, culture, and tourism, which are directly related to everyday lives of residents. This project is designed to support such reforms in the citizen service delivery system in order to enhance quality of life of local residents. This study is to draw implications from analysis for implementing the citizen service integrated information system in order to reform the citizen service delivery system effectively through examinations and analyses of citizen services provided by the central government. Especially focus on public utility charges depreciation simplification citizen service. Its implications are expected to offer a real contribution for central and local Governments that want to increase the productivity of implementing eGovernment service.

This survey was conducted to compare the housewife's food habit and food purchase behavior on healthy dietary life. The questionnaires were collected from 151 working housewives and 159 housewives in Daejeon. The average meal time was 20~30 min., 67.6% of respondents ate breakfast and bap with guk(72.9%) was the most favourite foods. Almost half of them ate egg, fruit, vegetable everyday. They concerned highly about less intake of frozen foods(64.2%) and food additives(61.6%) for wellbeing dietary life. Because of close distance and various foods items, big discount store was chosen as food purchase place. The most considering purchase factor was food additives in working housewife and nutrition in housewife(p<0.05). In grocery shopping, working housewife considered children and their husbands(p<0.05). The most important purchase factor was the freshness in vegetables fishes fruits seaweeds eggs. TV or Radio was utilized the most frequently to obtain the useful knowledge on healthy foods. It is suggested that practical information should be offered housewives to purchase proper foods within their income and to manage dietary life according to their family's health condition.

The ubiquitous environment is to support people in their everyday life in an inconspicuous and unobtrusive way. This requires that information of the person and her preferences, liking, and habits are available in the ubiquitous system. In this paper, we propose the context aware system that can provide the tailored information service for user in ubiquitous computing environment. The system architecture is composed of 4 domain models that can perform some pre-defined tasks independently. And we suggest the hybrid algorithm combined with fuzzy and Bayesian network to reason what information is suitable for user environment. Finally, we apply to agent based RGA(Research Guide Assistant).

The ubiquitous environment is to support people in their everyday life in an inconspicuous and unobtrusive way. This environment requires information such as the person, his/her preferences, and habits which is available in the ubiquitous system. In this paper, we propose the context aware system that can provide the tailored information service for user in ubiquitous computing environment. Our system architecture is divided into 4 domain models such as context awareness, presentation, interface and inference domain. Each domain model can perform some predefined tasks independently. And we suggest the hybrid algorithm combined with fuzzy and Bayesian method in order to reason what is the suitable information for user. We show the possibility for the real application through applying the system to the TGA (Tour Guide Assistant) for Kyoungju historical site.
