This study proposes a mathematical model to estimate the economic value of weather forecast service, among which the precipitation forecast service is focused. The value is calculated in terms of users' satisfaction or dissatisfaction resulted from the users' decisions made by using the precipitation probabilistic forecasts and thresholds. The satisfaction values can be quantified by the traditional value score model, which shows the scaled utility values relative to the perfect forecast information. This paper extends the value score concept to a collective value score model which is defined as a weighted sum of users' satisfaction based on threshold distribution in a group of the users. The proposed collective value score model is applied to the picnic scenario by using four hypothetical sets of probabilistic forecasts, i.e., under-confident, over-confident, under-forecast and over-forecast. The application results show that under-confident type of forecasts outperforms the others as a measure of the maximum collective value regardless of users' dissatisfaction patterns caused by two types of forecast errors, e.g., miss and false alarm.

The purpose of this study was to gain an understanding about urban housewives' stress in family financial management, their coping strategies, and their sense of economic well-being, which will eventually provide some baseline data for policy development. The findings of this study are summarized in the following. First, the mean score of the level of financial management-related stress among urban housewives was 2.61 when the maximum level was set at 5. In order to overcome the stress from financial management, housewives utilized various strategies, such as purchasing management, financial planning, financial information gathering, getting a loan, and delaying payments. The average level of economic well-being among urban housewives was 2.82 when the maximum level was 5. Second, among socio-demographic factors, the family's monthly income and the husband's job satisfaction were the two most significant factors that affected the level of financial management stress among housewives. Third, there was a difference in employing coping strategies according to the level of stress. The group with a higher level of financial stress employed more coping strategies than the group with, a lower level of stress. Fourth, there were differences in the level of economic well-being, depending on the types of coping strategies employed. Fifth, the results from regression analyses, which were conducted to determine the relative explanatory power of different independent variable groups including subjective factors, financial management stress, and coping strategies, showed that socio-demographic and objective economic factors significantly affected economic well-being.

This paper situates 63 provinces of Vietnam on a two-dimensional governance space, according to their levels of both economic and political governance, and systematically explains the two-dimensional distribution of provincial governance. It presents three sets of explanatory factors: the amount of foreign direct investment (FDI) that each province has attracted, the combination of provincial urbanization and population density, and the North Central Coast region factor. Provinces that score high in both economic and political governance tend to have received a good amount of FDI and to be highly urbanized and densely populated whereas provinces that score low in both governance dimensions tend to have the opposite characteristics. Provinces that are high in economic governance but low in political governance are those that have received the greatest amount of FDI and tend to be highly urbanized yet relatively sparsely populated. Provinces that are high in political governance but low in economic governance are characterized by a relatively small amount of FDI, low urbanization, and high population density. Finally, provinces in the North Central Coast region tend to score very high in political governance.

Purpose: The purpose of this study was to investigate factors affecting health promoting lifestyle in nursing students. Methods: A descriptive cross-sectional study was done using a convenient sampling (n=682) in a three-year nursing college. The health promoting lifestyle was measured by the instrument of Walker's and self esteem was measured by the instrument of Rosenberg's. Data were analyzed by descriptive statistics, chi-square test, oneway ANOVA and Stepwise multiple regression. Results: The average score of health promoting lifestyle was 2.34. The score of psycho-social well-being subscale was higher than that of health promoting behavior subscale. The highest score was on the interpersonal relations subscale, and the lowest score was on the physical activity subscale. The self-esteem, mental health status, satisfaction with school life, school year, perceived economic status, and gender accounted for 31.9% of the variance of health promoting lifestyle. Conclusion: Self-esteem was the most powerful influencing variable of the health promoting lifestyle, and physical activity was the lowest score of the health promoting lifestyle subscale. Therefor nursing educators should consider to include a health promotion program with increasing self esteem and physical activity in the nursing curriculum.

Method: The subjects of this study were 199 people aged over 60 who had been living in three rural area. Data were collected through a questionnaire survey from the 10th of July to the 10th of August 2003. Collected data were analyzed using descriptive statistics, t-test, ANOVA. Duncan's multiple-range test, Pearson's correlation coefficient and multiple stepwise regression with SPSS & SAS. Result: The average depression score was 11.09. As for the score of social support by supporter, the score of spouse' support was 13.36 out of 18 points, children's support 13.27, friends' support 11.40, neighbors' support 10.21 and siblings' support 10.20. The average score of quality of life was 132.26 out of 220 points. As for the score of the sub-areas of quality of life, the score was highest in economic status(32.18) and lowest in neighbor relationship (16.42). The score of quality of life was negatively correlated with the score of depression (r=-.014) and positively with the score of social support (r=.338). The suitable regression from the results of the multiple regression analysis to investigate factors influencing quality of life was expressed by y=58.341-$0.361x_1$+$1.492x_2$ ($x_1$: social support, $x_2$: depression) and $R^2$=.327. Conclusion: These results suggest that elderly people in rural areas with high quality of life is likely to be low in depression and high in social support. Therefore, it is necessary to develop health promotion programs in due consideration of depression and social support in order to enhance the quality of life of elderly people in rural areas.
