In order to generate a renewable energy-Methane, anaerobic systems fed with source separated food waste from university cafeteria were studied. At first, four reactors were evaluated with same feed components; content non-mixing anaerobic reactor without leachate withdrawal/recirculation, content mixing anaerobic reactor without leachate withdrawal/recirculation, content non-mixing anaerobic reactor with leachate withdrawal/recirculation and content mixing anaerobic reactor with leachate withdrawal/recirculation. From the first study, content non-mixing anaerobic reactor with leachate withdrawal/recirculation showed the highest gas production. From further study with this system, it was observed that leachate permeation rate within anaerobic reactor was very important factor for gas generation. The higher permeation rate, the more gas production was observed. It is assumed that 1kg of gas collector weight and C/N ration above 10 in food waste may cause gas consumption in the anaerobic reactor. The gas consumption was estimated by negative pressure build-up at gas collector. The negative pressure build-up must be explained to produce Methane from Food Waste.

This study examines the interaction effects between branded contents' ending types(happy ending, non-happy ending) and the level of product involvement(high involvement, low involvement) on consumer's negative responses. Results suggest that the level of product involvement had no significant effect on consumer responses since product on video clips was not closely linked to the contents' message. Selective empathy is identified as the happy ending type of branded contents had a greater effect on consumer's negative responses than the non-happy ending type of. It is an apparent new phenomenon shown among the young after 2000s. Moreover, the interaction between contents' ending types and the level of product involvement had a significant effect on consumer's negative responses. Two interaction terms (i.e. happy ending and low product involvement; non-happy ending and high product involvement) are the viable message strategies to weaken the consumer responses in terms of 'dislike'.

The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age($\leq$49 yr group) and those in group II 50 years up($\geq$50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in $\leq$49 yr group and 519.50mg in $\geq$50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in $\geq$50 yr group were significantly higher than those of $\leq$49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.

This study tests the path model which examines how the variables of past and present family dynamics, school adjustment, filed life events affect the adolescents'depression which in tum influencing their suicidal ideation. In the path model, the exogenous varialbes were negative parenting experience in childhood, maladjustment history of the family (e.g., alcohol, divorce), present parent-adolesecent communication, school adjustment, filed life events were used, whereas the adolescent depression was used as the mediated variable. The endogenous variable was the adolescent suicidal ideation. The respondents of the survey were 635 adolescent who were 1st and 2nd grade of high school located in Seoul and Busan. Using SPSS for Windows, the path analysis was done for male and female adolescents separately, since female adolescents were found to report significantly higher degree of depression and suicidal ideation then were male adolescents. The results of the path analysis were as followings. First, for both the male and female adolescents, depression was the strongest predictor of their suicidal ideation. Also, school adjustment strongly affected the adolescents'depression as well as their suicidal ideation. Meanwhile, filed life events indirectly influenced the suicidal ideation only through the depression. Second, for the male adolescents, negative parenting experience in childhood affected both the depression and suicidal ideation, while the parent-adolescent communication directly affected the suicidal ideation. Third, for the female adolescents, maladjustment family history and negative parenting experience did not affect their depression, but the suicidal ideation. Meanwhile, parent-adolescent communication was a significant predictor of female adolescents'suicidal ideation as well as their depression. In conclusion, discussion on different path of male and female adolescents'suicidal ideation was provided.
