This study, based on stages of behavioral change, was aimed at suggesting strategies for the adoption of moderate drinking habits for community-based health education designed to help rural people. An interview survey was conducted during the period from March 4 to April 5, 2002 by sampling 467 rural people living in 6 villages covered by a public healthcare clinic. The results of this study can be summarized as follows； 1. The perceived non-moderate drinkers were less prepared for behavioral change. 2. The heavier drinking habits were ‘drinking alone’, ‘meals accompanied by drinking’ and ‘drinking twice or more at a time’. The agricultural off-season and the custom of brewing liquor at home were negative environmental factors for moderate drinking. 3. The predisposing factors affecting moderate drinking were recognition of health, expectation of the drinking effect, etiquette encouraging overdrinking and control of drinking. The reinforcing factors were stress from ordinary life and perception of being loved. The enabling factor was accessibility to the public healthcare clinic. 4. Rural residents are less motivated to participate in health education for moderate drinking. Based on the above findings, health education strategies for each stage can be suggested as follows： 1) Pre-contemplation stage： improvement of perception, motivation, sharing of experiences, and reawakening. 2) Contemplation/preparation stag e： measurement of value, departure from the inertia against a change, formation of a habit, and reinforcement of the behavior. 3) Action/maintenance stage： creation of a social atmosphere, encouragement of participation, change of life style, and improvement of environment.

Objectives: This study was performed to assess the association between physical activity and the clustering of metabolic abnormalities among Korean children. The effect of substituting moderate to vigorous physical activity for the time spent in inactivity was examined as well. Methods: The study subjects were comprised of 692 (354 boys, 338 girls) 4th grade elementary school students. We used a modified form of the physical activity questionnaire that was developed in the Five-City Project. The subjects with clustering of metabolic abnormalities were defined as having two or more of the following five characteristics: waist circumference ${\geq}90\;%$, systolic or diastolic blood pressure ${\geq}90\;%$, fasting glucose ${\geq}110\;mg/dl$, triglycerides ${\geq}110\;mg/dl$ and HDL cholesterol ${\geq}40\;mg/dl$. We calculated the odds ratios to assess the effect of substituting moderate to vigorous physical activity for time spent in inactivity. Results: The risk of clustered metabolic abnormalities was inversely correlated with the increased time spent on moderate to vigorous physical activity, but the correlation was not significant. The odds ratio for clustering of metabolic abnormalities that represented the effect of substituting moderate to vigorous physical activity for 30minutes of sedentary activity was 0.87(95% Cl=0.76-1.01). Conclusions: These findings suggest that substituting moderate to vigorous physical activity for sedentary activity could decrease the risk of clustered metabolic abnormalities.

The first goal of this study is to confirm validity and reliability of service innovation and performance concepts in Chinese service industry and to verify positive relationship between the two concepts empirically. Furthermore, as the second goal of this study, we tried to check if Time Based Strategies and dFlexibility Based Strategies have positive moderate effect on the relationship. Based on the results of survey on 181 Chinese service companies, we verified that service innovation and performance are valid concepts and that the former has positive effect on the latter and, additionally, differentiation strategy, not cost leadership, showed positive moderate effect on that relationship.

To study the effect of dietary $\omega 6/\omega 3$ fatty acid ratios on the preneoplastic lesions and lipid peroxidation in rat hepatocellular chemical carcinogenesis, placental glutathione S-transferase(GST-P) positive foci area and numbers, glucose 6-phosphatase(G6Pase) activity, thiobarbituric acid reactive substances (TBARS) were measured. Male Sprague-Dawley rats were fed 5 different diets-low $\omega 6/\omega 3$ ratio with fish oil (Low-F), low $\omega 6/\omega 3$ ratio with perilia oil(Low-P), moderate ratio with perilia oil(Moderate), blend of 10 different commercial fats and oils(High-BL) and high $\omega 6/\omega 3$ ratio(High)-for 8 weeks. Hepatocarcinogenesis was induced by modified Ito model. The area of GST-P positive loci was the lowest in Moderate group and in ascending order of Low-F < Low-P < High-BL < High. But statistically, only Moderate and High groups were significantly different. The number of GST-P positive foci showed the same trend as foci area. The activities of G6Pase, membrane stability marker, were increased as $\omega 6/\omega 3$ ratio decreased. Lipid peroxidation values (TBARS) were the lowest in Low-F group and it is significantly different from Moderate, High-BL and High groups. When dietary $\omega 6/\omega 3$ ratio was moderate(4.06), hepatocarcinogenesis was suppressed compared with high or low $\omega 6/\omega 3$ ratios. Blend fat, commonly consumed among Koreans, did not show any suppressive effect on carcinogenesis because of high ratio(6.7). These results suggest that dietary $\omega 6/\omega 3$ ratio influences hepatocellular chemical carcinogenesis. It is recommended that appropriate $\omega 6/\omega 3$ ratio should be around 4.0. and we recommend to use more $\omega 3$ fatty acid in food preparation to reduce the risk of hepatocarcinogenesis.

This retrospective study evaluated the effect of age at first calving on the productive and reproductive performance in Holstein dairy cattle. Data were collected on 2,297 lactations from 19 dairy farms, including dates of birth, insemination, pregnancy, calving, and lactation and milk production (305-day milk yield at first lactation and lifetime milk yield). Lactation data were grouped based on age at first calving into the early (< 24 months, n = 414), moderate (24 ${\leq}$ and ${\leq}$ 28 months, n = 1,268), and late (> 28 months, n = 615) groups. The 305-day milk yield at first lactation was higher (p < 0.005) in the late group (8,461.9 kg) than in the early (8,130.8 kg) and moderate (8,261.9 kg) groups. Lifetime days in milk were shorter (p < 0.01) in the early group (1,045.7) than in the moderate (1,143.1) and late (1,110.7) groups, whereas the lifetime milk yield was higher (p < 0.05) in the moderate group (34,171.8 kg) than in the early group (31,791.6 kg). The second calving interval (days) differed (p < 0.0001) between the early (416.9), moderate (438.9), and late (455.3) groups. The culling rate at the first and second lactations tended to be higher (p = 0.08) in the early group (31.2%) than in the moderate group (26.0%), whereas it was intermediate in the late group (29.3%). In conclusion, dairy heifers aged 24-28 months at first calving showed a higher productive performance through an increased lifetime milk yield and a decreased culling rate.

Experimental isotherm compressive tests show that concrete behaviour is dependent on temperature. The aim of such tests is to reproduce how concrete will behave under environmental changes within a moderate range of temperature. In this paper, a novel constitutive elastic damage behaviour law is proposed based on a free energy with an apparent damage depending on temperature. The proposed constitutive behaviour leads to classical theory of thermo-elasticity at small strains. Fixed elastic mechanical characteristics and fixed evolution law of damage independent of temperature and the material volume element size are considered. This approach is applied to compressive tests. The model predicts compressive strength and secant modulus of elasticity decrease as temperature increases. A power scaling law is assumed for specific entropy as function of the specimen size which leads to a volume size effect on the stress-strain compressive behaviour. The proposed model reproduces theoretical and experimental results from literature for tempertaures ranging between $20^{\circ}C$ and $70^{\circ}C$. The effect of the difference in the coefficient of thermal expansion between the mortar and coarse aggregates is also considered which gives a better agreement with FIB recommendations. It is shown that this effect is of a second order in the considered moderate range of temperature.

A buried channel poly-Si TFT (BCTFT) for application of high performance integrated circuits has been proposed and fabricated. BCTFT has unique features, such as the moderately-doped buried channel and counter-doped body region for conductivity modulation, and the fourth terminal entitled back bias for preventing kink effect. The n-type and p-type BCTFT exhibits superior performance to conventional poly-Si TFT in ON-current and field effect mobility due to moderate doping at the buried channel. The OFF-state leakage current is not increased because the carrier drift is suppressed by the p-n junction depletion between the moderately-doped buried channel and the counter-doped body region.

The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.

To find the relation between exercise and cytokines, we examined the effect of the training intensity on the levels of cytokines, including interferon-gamma (IFN-γ), interlukine-4 (IL-4) and interlukine-4/interferon-gamma ratio (IL-4/IFN-γ ratio) in female Futsal players. Twelve well-trained female college Futsal players aged 19~22 participated in this study. The athletes completed 30-min of running at 60~65% maximal heart rate [moderate-intensity exercise], and 30-min of running at 75~80% maximal heart rate [high-intensity exercise]. peripheral blood samples were collected 24 h before and 24 h and 48 h after each of the exercise bouts. finding showed that The 30-min bout of moderate-intensity exercise induced a significant increase in IFN-γ (p=0.01) and significant decreases in IL-4 (p=0.001) and IL-4/IFN-γ ratio (p=0.003). And also, 30-min of running at 75~80% maximal heart rate induced increase in IFN-γ (p=0.07) and decreased in IL-4 (p=0.01) and IL-4/IFN-γ ratio (p=0.06) that these changes not significantly. In summary, exercise intensity can effect on the magnitude of changes in cytokines. It seems that moderate intensity exercise enhances cytokine pattern in female college Futsal players.

Purpose: The purpose of this study was to investigate the effect of the moderate drinking program based on social cognitive theory on changes in the drinking habits of college students with drinking problems. Methods: This study included a total of 68 college students with drinking problems. These participants participated in 10 sessions of a moderate drinking program in which social cognitive theory was applied. Changes in the cognition and behaviors of the participants were then investigated. Results: The moderate drinking program based on social cognitive theory for college students with drinking problems was effective in increasing the subjects' drinking-related knowledge (U=191.50, p<.001), enhancing their drinking refusal self-efficacy(t=8.02, p<.001), and changing their drinking-related attitudes (U=108.50, p<.001), drinking outcome expectancy (t=8.68, p<.001), amount of drinking in a single session ($x^2=25.72$, p<.001), number of drinking sessions per month ($x^2=10.05$, p=.006), and problem drinking behaviors (t=5.77, p<.001). Conclusion: These results can be used to inform a regular on-campus intervention programs for moderate drinking, and to implement education about moderate drinking, thereby increasing the success rate of drinking reduction.
