The high performance fiber reinforced cementitious composite (HPFRCC) controls the cracking development of the structure by inducing micro-cracking and strain hardening behavior after the initial cracking under the tensile conditions. Although, in Korea, the research about manufacturing the single-fiber reinforced cementitious composite or the mechanical properties of hardened status has been conducted, the research to apply the HPFRCC with multi-fiber is not sufficient. Hence, in this research, considering the workability and economic aspect for practical applications, the engineering properties of HPFRCC with combined long steel fiber (SL) and long organic fiber (OL) are evaluated such as workability and strength. As a result of evaluating the engineering properties of HPFRCC, the most favorable performance was obtained when the mixture contained 1.5% of combined SL and OL.

This research empirical explores impacts of performance information use of decision makers in distributing financial resources. Based on theoretical review and previous researches, we organized three scenarios of general public administration, economic policy, and environmental policy and investigated the difference in budget distribution between measured information and simple information of success or failure by randomly divided experimental and control groups who are not experienced bureaucratic processed. The results indicate that experimental group judge by using performance information with numeric indicators and has more diversified patterns than control group. We suggest that repeated experiments including bureaucratic members to reduce bias of expertness and generalize the decision making models using performance information in future researches.

Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.

This study was conducted to provide basic information on the nutritional status and health status of the rural elderly. The food intake, food habits and others health related factors were surveryed by interview method. The subjects was 200 people(71 male, 129 female) aged over 65 year in the Han-an area. The obtained results as follows; Their average age is 73.5$\pm$5.6. Mean height and weight of elderly men were 163 cm and 58.1 kg. respectively and 148.7 cm and 50.0 kg for women. The regularity appetite and frequency of eating snacks and eating out were higher in men than in women. The favorite snacks for men were alcohol fruit coffee and for women was fruit, candy, cookies and coffee. The daily alcohol drinking and smoking ration were 50.0%, 60.6% for men, respectively and 14.0%, 24.8 % for women. The nutritional intake ratio to RDA of men was significantly higher than women. Especially, the intakes of energy, Ca, Vit.A, Vit B$_1$, Vit B$_2$ niacin were extremely low in women. The frequency of alcohol intake was related to nutrient intake of women . There was a negative correlation between age. smoking rate and the nutritional intake. The pocket money, weight height appetite, and frequency of snacks showed a positive relation to nutritional intake. In conclusion the study shows that gender did influence food intake in the elderly, Food intake of women was extremely in deficit, because the most elderly rural women live alone. For successful aging. a program for rural elderly is needed on the govermment level, i.e actions to provide minimum economic life, food delivery and psychological/ physical health care through regional pubilc health centers.

Purpose: This study was done to examine symptom experiences and related factors in angina patients. Method: The participants were 92 patients admitted to C university hospital between October and December 2004. The tools used were a questionnaire on symptom experience related to angina developed by Gensini(Coronary Angiographic Gensini Score). Global Assessment of Recent Stress Scale and a tool measuring performance of health behavior. Results: The mean score for symptom experience was relatively low (M=27.65, SD=18.44) as was the score for coronary severity (Gensini score) was 16.30 point (SD=18.04). The mean score for perceived stress was moderate (M=30.16, SD=12.26). Compliance was relatively good in these patients with angina (M=61.55, SD=7.60). Analysis of the correlation of symptom experience showed a statistically significant positive relationship with perceived stress (r=.410, p=.000). There was significant negative relationship (r=-.251, p=.016) between symptom experience and compliance. In the regression analysis, symptom experience was found to be significantly influenced by stress ($R^2$=.168, p=.000), age ($R^2$=.057, p=.002), and economic status ($R^2$=.061, p=.007). These variables explained 26.2% of the variance in symptom experience. Conclusion: The results of this study provide evidence that symptoms of angina can present not only as chest pain itself but also with fatigue, shortness of breath, and sleep disturbance as the most common symptoms.

Using monthly AVHRR-NDVI composite images, global vector data and statistical information, land cover change patterns in Asia during the major growing season (June, July and August) were analyzed for each country. Specifically, explanations on NDVI changes were developed at a regional scale emphasizing human impacts on ground vegetation. The annual mean change in each country showed NDVI-gain trends in high latitude areas and some parts of eastern China and northern/western India. On the contrary, NDVI-loss trends were distinctive in Japan, Korea, some parts of southeastern China, Vietnam, Laos, Cambodia, Thailand, Myanmar and some parts in southwestern/eastern India. These patterns largely coincided with socio-economic information reflected by human behavior. The NDVI change trends showed significant correlation with forest area changes. Also, a multiple regression model showed that the NDVI change patterns were significantly dependent on the changes in forest area and total population.

Spatial plans, widely encompassing national or regional plans, are designed for an appropriate management of 'region',which is a complex of social, cultural and economic functions. Designing a spatial plan, therefore, is based on the understanding of the structure, function, and some other characteristics of the region concemed. Area stidies which have been conducted in the fields of geography, regional science and anthropology, have contributed a lot to establishing the whole range of the regional planning system. This is identified in three spheres: setting up planning units based on concrete area studies and appropriate regional divisions, dividing planning areas by the studies on goods and service purchase behavior, endowing specific functions to each planning area. Some suggestions have been made to intensify the connections between area studies and regional planning, which include consensus buiding, planning-oriented area studies by the standardized formatting and sharing of research products by commercialization.

Alcohol consumption is a major source of health problems, for example, alchol consumption is related to liver diseases. In addition, the social and economic costs related to alcohol consumption are enormous. This study was conducted to evaluate the current status and influencing factors related to the recognition and behavioral intention for both drinking and alcohol-reduction programs. Three effective alcohol-reduction programs of clinic program, mass education, and alliance were considered. To explain the health behavior for drinking and alcohol-reduction programs, a five-stage behavioral intention model was built and 500 questionnaires were completed through a telephone survey. Stages of the model composed of recognition of the programs, past experiences, present drinking status, intention for drinking, and behavioral intention for alcohol-reduction programs. As a result, recognition rates of the programs were low in general, therefore the strategies of education, public relations, and advertisement need to be pursued. The alcohol dependency resulted in the fact that success rate was 30％ although trial rate of alcohol-reducing was 23％. The necessity of alcohol-reduction programs were suggested. In addition, significant factors related to the intention for alcohol-reducing were individual attitude and reluctancy to pay their time and money. An insignificant factor was the attitude to their alcohol-reduction by other people. Behavioral intention rates for alcohol-reducing clinics were 4％, and those for mass education were 8％. There were very low purchase rates for clinic program, mass education, and alliance. In conclusion, evidenced-based and effective alcohol-reduction programs need to be encouraged to drinkers by medical doctors, and the strategies of education, public relations, and advertisement are also recommended. In addition, continuing legal and systematic support for alcohol-reducing would lower the drinking rate and ultimately contribute to the nation's health promotion.
