  • Korea is located in either low or moderate seismicity continental region. It is realized that design codes and underlying design concepts of high seismicity region may not be appropriate to low or moderate seismicity region. In this paper, test results on the seismic response of structures without seismic detailing are reexamined and compared with numerical analysis results. The seismic design concept based on limited ductility is proposed as an alternative seismic design approach in moderate seismicity regions.

  • In an attempt to examine the risk factors and analyze an odds ratio for risk factors associated with mild and moderate. severe hypertension, this study was carried out from August, 1987 to September, 1997. From periodic health examinations of insured adults, 747 subjects were assigned to nomotensives, mild hypertensives and moderate' severe hypertensives. Major findings obtained from the study are as follows: 1. The Body mass index(BMI) was revealed a significant difference among the 3 groups. Also, there was a significant positive correlation between the BMI and systolic, dyastolic blood pressure. 2. Cholesterol was revealed to be significantly different among the 3 groups. Also, there was a significant positive correlation between the cholesterol and systolic, dyastolic blood pressure. 3. Urine protein and a cardiovascular family history was revealed to be significantly different among the 3 groups. The presence of urine protein and cardiovascular family history were significantly higher in hypertensives than nomotensives. 4. A preference for salty food, a preference for flesh and the frequency of flesh eating were not significantly different among the 3 groups. 5. Smoking habits, frequency and duration of cigarette smoking were not significantly different among 3 groups. 6. The habit of alcohol consumption and the frequency and duration of alcohol consumption were not significantly different among the 3 groups. 7. The habit of exercise and its frequency and duration were not significantly different among the 3 groups. 8. Statistically significant elevated odds ratios were noted in the following BMI(mild hypertensives; 2.48, moderate. severe hypertensives ; 4.65), urine protein(mild hypertensives ; 2.37, moderate. severe hypertensives; 6.77), cholesterol(moderate. severe hypertensives ;1.64), cardiovascular family histoy(moderate severe hypertensives; 4.77). Based on these results, the significant risk factors of mild, moderate. severe hypertension were BMI, cholesterol, urine protein, and family history, but diet, smoking, alcohol consumption, and exercise had no significant association.

  • Purpose: Adolescent obesity is a growing problem. This study examined the relationships between different types of physical activity and obesity in male and female middle and high school students. Methods: This study used the Korea National Health and Nutrition Examination Survey data of 2007. The study included 282 male and female middle and high school students who completed health survey questionnaires regarding physical activity. Physical activity was measured with vigorous and moderate activity and walking. BMI was used as an obesity indicator. Analyses were done using descriptive statistics, ANOVA, and chi-square test. In addition, multiple logistic regression were conducted to investigate the relationship between physical activity and obesity when adjusting for covariates. SAS/WIN 9.1 was used. Results: Boys spent more days in vigorous and moderate physical activity than girls (p for vigorous activity: <.001, for moderate activity: <.001). There was no significant difference in walking activity between boys and girls and between middle and high school students. Only days spent in vigorous activity was significantly higher in middle school student compared with high school students (p=.013). According to the relationship between physical activity and obesity, moderate physical activity was significantly related to BMI for high school boys (p=.041). However, when adjusting for age, sex, school, parental income, daily caloric intake, physical activity was not significantly related to obesity. Conclusions: The results showed that male and female middle and high school students spent not enough days in doing low moderate and vigorous physical activity. Thus, this strengthens the need to increase physical activity level in these populations. In spite of non-significant relationship between physical activity and obesity from multivariate analysis, increasing moderate physical activity for high school boy could be effective to prevent and manage obesity, since significant difference between moderate activity and obesity in this population.

  • Purpose: We assessed the treatment result of the distal chevron osteotomy in the patients with moderate to severe hallux valgus. Materials and Methods: In a total of 28 cases of hallux valgus in 20 patients, underwent distal chevron osteotomy between July 1999 and February 2001, were enrolled in this study. 21 cases were moderate and 7 cases were severe. The preoperative average hallux valgus angle and 1st-2nd intermetatarsal angle of the two groups were $31.5^{\circ}$, $15.8^{\circ}$ in moderate cases and $44.1^{\circ}$, $17.3^{\circ}$ in severe cases, respectively. Radiologic evaluation was done preoperatively, postoperatively and on the final follow-up visit using weight-bearing radiographic imaging to determine the hallux valgus angle and 1st-2nd intermetatarsal angle. Results: Radiographic evaluation revealed hallux valgus angle and 1st-2nd intermetatarsal angle in moderate cases to be $13.0^{\circ}$, $11.3^{\circ}$ (postoperatively and in severe cases $15.6^{\circ}$, $10.9^{\circ}C$, postoperatively. On final follow up, the results were $14.5^{\circ}$, $11.6^{\circ}$ in moderate cases and $18.3^{\circ}$, $11.9^{\circ}$ in severe cases, respectively. Conclusion: Distal chevron osteotomy can be usefully applied to the treatment of moderate to severe hallux valgus.

  • The purspose of this study is to examine the undergraduate students' attitudes, salient beliefs, perceived self-control and intentions for moderate drinking behavior of their own. Two hundred and twenty five students in two universities in Seoul and Suwon participated in this study. Questionnaires developed by this investigator under the guidance of the theory of planned behavior were used to collect data, Descriptive statistics, t-test, ANOVA. Pearson correlation coefficients. and multiple regression were used to analyze the data. The majority of the students showed positive attitudes toward the moderate drinking behavior. Students perceived conflict messages. however. from their significant others about their moderate drinking behavior. While parents and other family members as sisters and brothers strongly supported the moderate drinking behavior of students, friends and school-mates did not. More than half of the students did not intend to reduce their alcohol consumption in the near future. Students' attitudes and perceived self-control were the predictor variables of the intention while subjective norms were not. Students who intended to reduce their alcohol consumption showed a more positive attitude, subjective norm, and higher perceived self-control scores than who did not. These students who were intent for moderate drinking behavior spent less money for drinking, had less opportunities to drink, and drank small amounts of alcohol Moderate Drinking Behavior programs focusing on students who were heavy drinkers, however, did not intend to reduce their alcohol consumption should be developed focused on their characters. Programs for students who intended to reduce their alcohol consumption also recommended to help the students' positive intention continued.

  • Purpose: The purpose of this study was to investigate if companies' efforts of environmental management practices have positive effect on the companies' performance in the first stage of study. In the second stage, we tried to confirm whether the degree of companies' making efforts on cost leadership strategy and quality leadership strategy function as moderate variable on relationship between environmental management practices and performance. Methods: The collected data through survey were analysed using multiple regression model in the first stage of the study and moderate regression model in the second. Results: The results of this study are as follows; environmental management practices have positive effect on corporate performance. Moreover, much effort on quality leadership strategy has limited significant moderate effect on relationship between environmental management practices and performance, while much effort by companies on cost leadership strategy does not have significant moderate effect on the relationship between the two variables. Conclusion: Manufacturing and services companies in Korea need to make effort for environmental management practices to improve corporate performance. Moreover, if that efforts are combined with quality leadership strategy, they can expect synergy effect with environmental management practices for performance improvement.

  • Purpose: The purpose of this study was to investigate if purchasing companies' efforts of supplier development activities to supplier companies have positive impacts on the purchasing companies' performance as the first step. In the second step, we tried to confirm if the concept of Supply Chain Corporate Social Responsibility activities and Coexistence activities take the roles of moderate variable on relationship between supplier development and three performances respectively. Methods: The collected data through survey were analysed using multiple regression for the first step of the study and moderate regression for the second one of it. Results: The results of this study are as follows; supplier development efforts effect on all three performances positively. Moreover, Supply Chain CSR has significant moderate effect on relationship between supplier management and corporate performances, while Coexistence does between supplier management and logistics performances. In the case of relationship between supplier management and production performances, both Supply Chain CSR and Coexistence show significant moderate effect. Conclusion: Manufacturing companies in Korea need to make effort of supplier development in selective way when they want to practice Supply Chain CSR and Coexistence concurrently considering strategies and objectives.
