Epidemiological studies have indicated that a relationship between overweight and cardiovascular disease exists. To assess the relationship of unfavorable changes in serum lipid concentrations, apolipoprotein B, lipoprotein(a), blood sugar and blood pressure to anthropometric variables, nutrient intakes and dietary behavior,64 obese children were chosen as subjects and 24-hour dietary intake, dietary behavior as well as blood pressure, apolipoprotein B, lipoprotein(a), three kinds of cholesterol concentrations were measured in November 1976. More than half(57.8%) of the children had serum cholesterol concentrations over 175mg/d1, and 26.6% of them had over 200mg/d1 and this group could be classified as a high risk group. Abdominal obesity as measured with waist circumference and waist hip ratio was negatively co..elated to high density lipop개tein(HDL) cholesterol. Dietary behavior rather than nutrient intakes appeared to have associations with unfavorable lipid profiles. Total dietary behavior scores and fish and bean product consumption had strong correlations with potentially atherogenic lipoprotein concentrations. This study suggests that fir the early prevention of cardiovascular disease, waist hip ratio together with obese rate should be included in selective programs to identify risk group of children in Korea. furthermore, interventions in cardiovascular disease risk groups in obese children should emphasize maintenance of ideal body weight through reducing body fat and adopting desirable dietary behaviors such as increasing intake of fish or bean products.

Objectives : This study was performed to evaluate the relationships between psychosocial characteristics and changes in the stage of breast cancer screening behavior. Methods : The 474 study subjects were randomly sampled from 21,459 women(age range, 40-70 years) who were eligible for the Korean National Cancer Screening Program in 2006 in Jinju, Gyeongsangnam-do. The information, including behaviors and sociodemographic characteristics, attitudes, subjective norms and self-efficacy, was collected by trained interviewers via home visits. The breast cancer screening stages were grouped as precontemplation, contemplation, action, maintenance and relapse, according to Rakowski. Results : Of the 474 women, 18.8% were in the precontemplation stage, 23.3% were in the contemplation stage, 13.1% were in the action stage, 36.6% were in the maintenance stage, and 8.2% were in the relapse stage. The distribution of stages was associated with attitude, subjective norms and self-efficacy(p for trend<0.01). To investigate the overall relationship between the variables, we conducted a linear structural equation model analysis based on the theory of planned behavior. The subjective norms and self-efficacy influenced the stage of the women's screening behavior. Conclusions : We should target on self-efficacy about the screening behavior of women by performing timely, thoughtful interventions. The support from family members, friends and other people is crucial for women to undergo breast cancer screening and to improve the breast cancer screening rate.

Health behavior constitutes the single most important factor in an individual's health maintenance program. Pender's health promotion model emphasizes the positive aspects of health-seeking behavior hut omits some negative ones. Although Pender's work does include the concept of barriers, the main focus is upon health habits rather than upon the interaction between the consumer and the health care system. Therefore, since individuals actually do face many barriers in their health-seeking behavior, the present study deals with negative concepts-the barriers to health and healthy behavior. For this reason the expression health-seeking behavior was chosen over health promotion. In conclusion, the results show that barriers to health-seeking behavior are causal factors that could explain and predict the health-seeking behavior of middle life women. Midlife women shows that they have barriers to health-seeking behavior especially in inconvenience, cost, healthcenter site-related problem, relationship, fear. These findings suggest the need to develop a nursing strategy to improve the empowerment of self-determination in middle-aged women. Consequently, a goal of nursing care for middle-aged women should be to help them pursue health care with a greater degree of self-sufficiency.

The purpose of this study was to explain the relationship between health promoting behavior and self-esteem, and the relationship between health promoting behavior and self-efficacy. The instrument of this study was a structured questionnaire included health promoting lifestyle, self-esteem and self-efficacy. The data were collected from August 24 to September 3, 1999 and analyzed by Cronbach alpha, descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient and stepwise multiple regression by using SPSS/PC+ program. The results of research were as follows : 1. The average score of performance in the health promoting behavior variables was 2.61. The variable with the highest degree of performance was the sanitary life(3.14), whereas the one with the lowest degree was the professional health maintenance(1.50). The average score of self-esteem was 2.89, and self-efficacy was 6.60. 2. There was significant difference according to the demographic variables. The total health promoting behavior was predicted by age, religion, monthly income. personality, perceived health status and frequency of exercise. Self-esteem was predicted by religion, monthly income and personality. Self-efficacy was predicted by age, religion and personality. 3. There was a significant correlation between health promoting behavior and self-esteem, self-efficacy. 4. Self-efficacy was the highest factor (variable) predicting health promoting behavior. A total of 44.7% of the variance was explained in the total health promoting behavior by the self-efficacy, frequency of exercise, self-esteem, perceived health status and personality. In conclusion, this study revealed that self-efficacy, self-esteem may be important factors that can improve health promoting behavior. Therefore the findings of this study may provide significant basic data for health promoting program development.

With the development and utilization of urban underground space, the artificial ground freezing technology has been widely used in the construction of underground engineering in soft soil areas. The mechanical properties of soft clay changed greatly after freezing and thawing, which affected the seismic performance of underground structures. In this paper, a series of triaxial tests were carried out to study the dynamic response of the freezing-thawing clay under the seismic load considering different dynamic stress amplitudes and different confining pressures. The reduction factor of dynamic shear stress was determined to correct the amplitude of the seismic load. The deformation development mode, the stress-strain relationship and the energy dissipation behavior of the soft clay under the seismic load were analyzed. An empirical model for predicting accumulative plastic strain was proposed and validated considering the loading times, the confining pressures and the dynamic stress amplitudes. The relevant research results can provide a theoretical reference to the seismic design of underground structures in soft clay areas.

Judging from the occasional occurrences of minor and major earthquakes in Korean peninsula, it is generally considered that Korean peninsula is not located in safe zone from earthquake any more. The worldwide damages from earthquake in public buildings such as bridges are also urging the necessity for an appropriate earthquake proof action. The elastomeric bearings have been used in seismic isolation design of bridges. and elastomeric bearings are quite ideal ones which allow movement and rotation in all directions without restraining superstruture. Within the limits of this study on dynamic behavior of the LBR for seismic isolation design, the reaearch results revealed that the Laminated Rubber Bearing(LRB) is useful in bridges for seismic isolation design. In addition, the relationship between the shape factor and compressive strength is linear. It was also found that the compressive strength gets higher as the shape factor increases.
