Objective: The purpose of this study was to understand the needs of teachers in daycare centers for preschoolers in providing health education and health care services and to identify competencies and barriers to health education among the teachers. Method: A total of 410 teachers from 496 public daycare centers were recruited. Participating daycare centers were selected using a stratified sampling method. Data were collected from June to August 2002 using mailed questionnaires. Result: About 37% of the daycare centers provided health education more than 6 times during the past year and 92% provided annual health screenings. Traffic safety, personal hygiene, and sexuality education were most frequently provided. Regarding in-service education for daycare teachers, 62.7% had obtained health related education. Sexuality education, traffic accident, and injury prevention were the main topics for the in-service education.

The purpose of the study is to find the factors influencing small or middle size clinics and hospitals CEOs' expectation level on the affiliation with the large size teaching hospitals. Data for analysis was collected to use self-administrative structured questionnaire on 164 CEOs of small or middle sized clinics and hospitals affiliated with large sized teaching hospital located in Kyung Ki Province. For the study, the researchers develop the constructs for questions on the expectation on the affiliation, the attitude such as confidence, knowledge on the affiliation, previous relationship of the affiliation, and selection guideline of the affiliation with exploratory factor analysis and reliability test. Through the confirmative factor analysis using AMOS 4, the researchers develop constructs based on exact relationship between constructs and questions. CEOs' expectation level on the affiliation is influenced on attitude or confidence, gender, types of clinics and hospitals, distance to the affiliated large hospital, types of recommender, and number of affiliated hospitals. Large sized hospitals that want to affiliation with other clinics and hospitals can promote the affiliation to consider these factors from the results.

Nowadays, Internet shopping malls have been popularized since the broadening of users of Internet and the advantage of on-line purchasing, Small and medium-sized enterprises, however, are still having difficulties in building Internet shopping malls due to the lack of technical knowledge and burdensome expenses. In this paper, we present an implementation of the Web Mall Admin Tool System by the integration of admin menus based on a public program. The system has several advantages of (1) reducing expenses for building a mall site, (2) making possible to build an shopping mall well-suited for the work environment of companies (3) providing available maintenance. Therefore, this provides the solution to enterprises that have trouble with building their own web malls because of expenses and maintenance.

Knowledge of the physical locations of access point of WLAN is becoming increasingly important with the rise of location-based services. In this article, we propose a new AP localization method using neural network approach. Basic theory and properties are derived for precise outdoor AP localization using GPS location information and RSSI. Rules for neural network model are derived and simulation has finally been done to demonstrate the efficiency of the proposed method. The simulation results show that the proposed method can result in AP localization with very. low error probability.

Purpose : The objective of this study was the development and validation of a scale to measure the self-care of patients with chronic obstructive pulmonary disease(COPD) in Korea. Method: Self-care scale was developed based on the self-care activities patients had to carry out in order to manage their COPD. The original scale contained 34 items rated along a five-point Likert scale and was reviewed by 18 professional nurses and 10 Korean patients with COPD for content validity. Subsequently, patients with COPD were asked to complete this 23-item scale and further tests were done with the 125 useable responses. Result: Factor analysis identified eight factors-'maintaining a clean air way', 'taking medication', 'support from family', 'preventing infection', 'managing symptoms', 'breathing exercising', and 'taking in nutrition'. The internal consistency of the total scale was Cronbach's α=0.7226. These eight factors explained 60.8% of total variance. There was correlation among Korean Self-Care Scale score, administration level, and knowledge level but there was no correlation to patients' satisfaction with medical services. Conclusion: The 23 item questionnaire positively identified 8 areas defined important for COPD patients. Further studies are required to see how these can be integrated into patient education.

Social Network Service (SNS) has been played an important role in the life with the expansion of the modern technology in the cellular communication. More knowledge and understanding should be inevitable even if companies have taken advantage of SNS through word of mouth as one of the new paradigm. In most cases the crucial benefit or peculiarity of SNS has been overlooked because only general aspects of SNS have been applied in the online situation. As a result of this, same paradigm has been considered in reality as SNS was just used one of the marketing tools. However, essential aspects of SNS were investigated to see the relation of usage intention and word of mouth in this study. The hypothesis of the effect of continuous intention of the usage, trust and word of mouth was made and reviewed statistically. The statistical analysis showed there was significant among relationship, context, perceived service quality and continuous intention of the usage. In addition to that, self-expression, relationship, perceived service quality and trust were significant. Finally the continuous intention of the usage and word of mouth was significant as well. Based on this study, SNS provided by the companies could be effective to the customers in terms of word of mouth while different trend was shown in terms of trust.
