Nowdays, adjacent loading bringing enormous harm to the existing bridge in engineering construction. In this paper, the influencing mechanism of adjacent loading to pier and Law of displacement of pier is researched through living examples, and the safe influence area has been defined. Research shows that: the main damages to piers is caused by the side loading; lateral displacement index of pier top surface is more conservative than the pier additional stress index; it is secure when the distance of adjacent load is 0.5 times of the height of accumulation or 6m, otherwise it would be very scary, and the monitoring measure is necessary.

Biopolymers, polymers produced by living organisms, are used in various fields (e.g., medical, food, cosmetic, medicine) due to their beneficial properties. Recently, biopolymers have been used for control of soil erosion, stabilization of aggregate, and to enhance drilling. However, the inter-particle behavior of such polymers on soil behavior are poorly understood. In this study, an artificial biopolymer (${\beta}$-1,3/1,6-glucan) was used as an engineered soil additive for Korean residual soil (i.e., hwangtoh). The geotechnical behavior of the Korean residual soil, after treatment with ${\beta}$-1,3/1,6-glucan, were measured through a series of laboratory approaches and then analyzed. As the biopolymer content in soil increased, so did its compactibility, Atterberg limits, plasticity index, swelling index, and shear modulus. However, the treatment had no effect on the compressional stiffness of the residual soil, and the polymer induced bio-clogging of the soil's pore spaces while resulting in a decrease in hydraulic conductivity.

This study was intended to investigate the effects of nutritional, physical and environmental conditions on the bone status of 102 pre and post menopausal women living in Ulsan area. The results of this study are summarized as follows : when subjects were classified into two groups by bone status, there were significant differences in age, calcium index, serum estrogen and physical activity between two groups. Average daily calcium intake of subjects was 682.9 (149.2)mg, which is almost same as RDA, but 41.1% of the subjects consumed calcium below RDA. Calcium index(p<0.05), serum estrogen(p<0.001), physical activity(p<0.001) of poor bone group were significantly lower than those of good bone group. Although there was not a significant difference between bone status and other influential factors, such as family type, skip meal, alcohol drinking, smoking and BMI, each has been shown to have an effect, if slight, on the bone status.

Purpose: This study aimed to identify the associated factors of the perceived health status of the elderly in Korea and to provide basic data for developing nursing interventions for the elderly's health management. Methods: This study used a descriptive correlational research design. The subjects of this study were 335 elderly people over 60 yr living in an urban city. Data were collected through personal interviews using questionnaires from September 2006 to March 2007. Empirical indicators of perceived health status were measured by SF-36, nutritional screening initiative (NSI), activities of daily living (ADL) Index, and instrumental activities of daily living (IADL) scale. The collected data were analyzed by descriptive statistics, Pearson's correlation, and hierarchical regression. Results: The mean age of the subjects was 72.8 and 57.0% of subjects were female. 41.5% of variance in physical health was explained by nutrition, ADL, IADL, and the number of years attending school. Among them the most important factor was ADL. 13.2% of variance in mental health was explained the number of family, nutrition, and IADL. Among them the most important factor was nutrition. Conclusion: It is necessary to develop supportive interventions for improving the perceived health status of elderly people by considering the most important factors shown in this study.

The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.

Background: The purpose of this research was to investigate the factors affecting the low back pain of workers in hospital. 214 subjects waking at two general hospitals in Yosu city participated in this survey. Subjects consisted of doctors, nurses, medical engineers, officers and general laborers. The survey data were collected by a written questionnaire which made out by themselves for 25 days, from fourth August to 29th August, 2008. Methods: The questionnaire consisted of four categories, general, occupational, working habitual and the daily living characteristics. The collected data were analyzed by Chi-square test based on the present or absent of low back pain. Results: 1. In the general characteristics, low back pain had no significant relationship to all factors, sex, ago, body mass index, weight and height. 2. In the occupational characteristics, the phase of distribution of low back pain had statistical significant differences in the working hours a week, satisfaction of pay, satisfaction of occupation(p<0.05). However low back pain did not significantly related to the kind of occupation, period of work and degree of stress. 3. In the habitual characteristics, low back pain was significantly influenced by working posture, frequency of using lumbar and heavy material lifting, monotonous repetition of working operation and noise(p<0.05). No significant difference was shown in the factor of convenience of chair. 4. In the daily living characteristics, low back pain shown the significant differences in walking time a day, status of health and smoking pattern(p<0.05). there were, however, no significant differences in the aspect of the kind of house and bed, sleeping attitude, driving, riding time on the vehicle, exercising, frequency of cultural life and drinking alcohol. Conclusion: when I see above resultants totally, it appears a higher incidence caused by working environment rather than living habit and then consequently compared to hospital workers, they also have high incidence like others. In order to reduce incidence of low back pain and enjoy the our life we need to educate ourselves preventing program for low back pain and try to effort for preventing of low back pain on each department and individual.

To investigate the status of farmers health management for health promotion, and for checking the effect of village health care center during 1 year, 746 subjects were selected with cluster method in 8 provinces of Korea. The most frequent group was 40th of age (39%) : elementary school graduates (32%) The self-conscious of health status tested with CMI (Cornell Medical Index) questionnaire, the subjects in the village of health care center had lower health status than those of conventional village. The farmers living in the village with health care center had longer agricultural work (p＜0.05) and more frequency of spraying pesticides in the fields. The subjects of living the village of health care center were frequently exercise (34%) with health appliance use methods (30%), but the duration time of exercise was similar, Dietary habits and agricultural work condition were similar between two groups. For the fatigue recovery, steeping and bathing were most favorite methods, but exercise was lowest. It was significantly different between 2 groups the fatigue recovering methods, the subjects of village with health care center were more doing exercise (p＜0.01), less sleeping (p＜0.01) than those of conventional village. The working condition of self-estimated of farmers was not good, only 8.7% was thought pleasant condition. Of the various health factors, exercise, nutrition, and working situation would be more important. Considering on farmers exercise, it was very weak point for health management. The foundation and leading of the Farmers health care center was encouraged to farmers. For more effective operations, the experts education, easy and funny exercise program, and health promotion committee for administrators would be needed. The better systemic and continuous exercise programs should develop for associating livelihood. Funding for this project provided by the ministry of health and welfare of Korea.

The purpose of this study was to investigate the dietary habits and the consumption patterns of convenience foods by university students according to where they reside. The subjects were 572 university students in Changwon and Masan who were divided into three groups by their residential type; students living with their parents (n=297), self-boarding students (n=139), and students living in a dormitory (n=136). This survey was conducted using a self-administered questionnaire. Among all students, 22.4% skipped breakfast, and the major reason was lack of time (38.1%). Convenience food intake at lunch was 39.1%, and that of snacks was 35.4%. In particular, convenience food intake at lunch was 45.9% for students living with their parents, 30.9% for those self-boarding, and 32.6% for those living in a dormitory (P<0.01). Approximately 66% of the students said that the reason they bought convenience food was that it was easy to cook. Those who were residents of a house (P<0.001) believed that nutritional imbalance was a problem with convenience food. The students who lived in the dormitory ate frozen fried pilaff (P<0.01), canned vegetables (P<0.05), packed kimchi (P<0.001), and Ramyon cups (P<0.001) more, while the self-boarding students ate Ramyon (P<0.05) more. The results suggest that it is necessary to educate people how to buy reasonably by understanding the interrelationship between convenience food and health care and by checking the nutrition index label on convenience foods.
