Health Belief Model is a socio-psychological theory of decision making to individual health-related behaviors. This study was aimed to develop an effective education program for hypertension based on health belief model. The main factors of health belief model were investigated by focus group interview (FGI) with 23 hypertensive or prehypertensive subjects aged over fifty years. 'Perceived susceptibility' to hypertension was family history, neglect of health care, preference for salty food, broth of soup and stew. Lifelong medication, complications, and medical costs were reported as 'perceived severity' of hypertension. 'Perceived benefits' of hypertension management were decrease of medicinal dose, reduction of medical costs, and healthy eating habits of the family, while 'perceived barriers' were lack of palatability of low salt diet, convenience-oriented dietary habits, and limited choice of foods when eating out. Subjects mentioned TV health programs, public health center programs, and advice from doctors and family as 'cues to action' of hypertension management. These qualitative information provided basis for developing a nutrition education program for hypertension which could be implemented in the public health center. Eight week program was composed of understanding hypertension, risk factor management (eating habits, weight), low salt diet (principles, cooking), advanced management for healthy diet in 2 sessions, and summary. Each session was designed to alert the susceptibility and severity, to emphasize the benefits, and to reduce the barriers by providing dietary monitoring, practical advice, and action tips.

This study attempted to examine the structural characteristics of the social network of nursing units by dividing them into a job-related advice network and a friendship network, and to analyze the relationship between nurse organizational commitment and intent to leave. The subjects were 420 nurses working in 4 hospitals and 30 nursing units. Data were analyzed using UCINET 6.0, SPSS 20.0 and HLM 7.0. In job-related advice networks, degree centrality of head nurse contributed to organizational commitment. Network density contributed to intent to leave. In friendship networks, closeness centrality of head nurses and betweenness centrality of charge nurse contributed to organizational commitment. Density and betweenness centrality of charge nurses contributed to intent to leave. Accordingly, it is necessary to foster good relationships between nurses and to develop various types of strategies for building effective networks.

The purpose of this study is to investigate impulse buying and the searching for sources of information among males and females in their 20s by their utilization of sales promotion in an internet fashion shopping mall. The findings were as follows: First, there was a statistically significant difference in the use of sales promotion by age and gender. Second, two factors, such as a price-oriented utilization of sales promotion and a non price-oriented utilization of sales promotion were extracted from the analysis of sub factors of the utilization of sales promotion in an internet fashion shopping mall. Third, five factors, including affective impulse buying, provocative impulsive buying, situational impulse buying, reminder impulse buying, and pure impulsive buying, were extracted from the analysis of sub factors of impulse buying in an internet fashion shopping mall. Fourth, the utilization of sales promotions in an internet fashion shopping mall had statistically significant effects on the sub factors of impulse buying, provocative impulse buying, situational impulse buying, reminder impulse buying, and pure impulse buying. Fifth, the analysis of the correlation between the utilization of sales promotion and the searching for sources of information revealed that price-oriented utilization of sales promotion had a correlation with DM or text message, advice from friends or family, advice from a sales person, information from friends or colleagues, celebrity supporters on TV dramas or movies, and product commercials and information.

For a safe and stable supply of blood in Korea, 'Blood Donation Houses' are springing up all over Korea to advertise and improve the awareness on blood donations. This research will conduct a study on such blood donation centers, their conditions and problems. It will furthermore provide solutions to raise the level of comfort to donators and help nurses for a better working environment. The research will be conducted in 'Blood Donation Houses' that were established by 4 centers of the Korean Red Cross in Seoul after 1993. Any houses that are temporary (containers, buses, smaller than 15 pyung) were excluded from this study. In order to investigate changes of these houses, the ones analyzed and recorded in the 2002 data were used as a basis for comparison. A total of 16 houses were selected for this study. 5 houses were closed after the initial study of 2002, and 6 houses were not available for research upon above mentioned criteria, leaving 9 houses from the original 2002 data. 7 additional houses were opened after 2002, which were included in this study. The research was conducted by a close study of written materials on the historical and theoretical viewpoint of blood donations, as well as visits to the actual Blood Donation Houses. The conclusion will offer solutions to necessary functional and working space, and lighting in such houses on the basis of above analyzed theoretical and practical data.

Data mining techniques enable us to generate useful information for decision support from the data sources which are generated and accumulated in the process of routine organizational management activities. College administration system is a typical example that produces a warehouse of student records as each and every student enters a college and undertakes the curricular and extracurricular activities. So far, these data have been utilized to a very limited student service purposes, such as issuance of transcripts, graduation evaluation, GPA calculation, etc. In this paper, we utilized Holland career search test results, TOEIC score, course work list and GPA score as the input for data mining, and we were able to generate knowledge and rules with regard to the college road map advisory service. Factor analysis and AHP(Analytic Hierarchy Process) were the primary techniques deployed in the data mining process. Since these data mining techniques are very powerful in processing and discovering useful knowledge and information from large scale student databases, we can expect a highly sophisticated student advisory knowledge and services which may not be obtained from the human student advice experts.

BACKGROUND/OBJECTIVES: The aims of the present study are: 1) to quantify sodium consumption of patients with unstable or uncontrolled hypertension, 2) to investigate if reduced sodium intake can lower BP in these patients, and 3), to assess the acceptability and feasibility of this approach. SUBJECTS/METHODS: This study included 25 adults (age: 50+ years) with frequently elevated BP or patients with uncontrolled, uncomplicated hypertension despite drug treatment in a general practice setting. BP and salt intake (24h urinary excretion and food records) were measured at baseline and after a sodium reduced diet. RESULTS: Mean (${\pm}SD$) systolic (SBP) over diastolic (DBP) blood pressure (mmHg) at baseline was $150.7({\pm}9.5)$/$84.149({\pm}5.6)$. Mean urinary sodium excretion was 146 mmol/24h. A reduction of 28 mmol sodium excretion decreased SBP/DBP to $135.5({\pm}13.0)$/$82.5({\pm}12.8)$ (P < 0.001). After one month of no dietary advice, only in 48%, SBP was still ${\leq}140mmHg$. CONCLUSION: Assessment of sodium intake using food records, 24h urine collections and probing questions to identify use of sodium containing supplements or drugs are essential for tailored advice targeted at sodium intake reduction. The results of the present study indicate that reduced sodium intake can lower BP after 4 weeks in unstable or uncontrolled hypertensive patients.
