  • The aim of this paper is to examine the buffering effect of family cohesion in the relationship between depression and suicidal risk among adolescents, adults, and the elderly. To achieve the research aim, surveys were conducted in 10 cities across the country for 399 adolescents, 473 adults, and 370 elderly from May to August 2010. Major findings of the data analysis are as follows. First, while, in the relationship between depression and suicidal risk, the elderly were the highest, followed by adolescents and adults in descending order, in family cohesion, adults were the highest, followed by the elderly and adolescents. Second, the analysis of the buffering effect of family cohesion in the relationship between depression and suicidal risk showed that it was significant only for adolescents and adults, which means that for those two groups family cohesion alleviates the effects of depression on suicidal risk, demonstrating the necessity of strengthening family cohesion to reduce suicides among the two groups of people. But, for the elderly for whom family relationship is more important than any other age group, the buffering effect of family cohesion in the relationship between depression and suicidal risk was not proved. The interpretation of this phenomenon is given in the part of the paper where the characteristics of the suicide of the old age group is discussed.

  • The purpose of this study was to examine the impact of psychosocial protective and risk factors on problem drinking among American adolescents. In addition, this study investigated the compensatory and buffering effects of psychosocial protective factors. The sample consisted 4,362 10th graders taken from the Monitoring the Future Study 2002. This study performed the hierarchical regression analysis for data analyses. The main findings provided that friend influence, sensation-seeking, and tolerance of deviance had significant positive relationships with problem drinking as risk factors. This study also revealed that negative perception on drinking, parental bonding, school bonding, and prosocial activity had significant direct impacts in decreasing problem drinking, which explains the compensatory effect of protective factors. Additionally, this study showed that negative perception on drinking had a significant buffering effect moderating friend influence on adolescents' opportunities exposed to problem drinking. The results of this study suggest some practical implications for preventive intervention programs that target adolescent problem drinking.

  • The purpose of this study is to examine the relation between parental strain and marital adjustment of employed mothers after their transition to the parenthood, and to investigate buffering effect of social support on the relation. The parental strain variables (physical strain and emotional strain) appear to be significant predictors of marital adjustment for employed mothers with first baby. The analysis on interaction effect indicates that social support can be a positive buffering indicator. A comparison reveals that mothers with high physical strain have significantly higher marital adjustment than those with low strain. But in the context of high social support, the difference of marital adjustment between the two mothers is reduced.

  • This study investigated the relationship between social support and the well-being among the unemployed. Special attention was given to the empirical tests of the main effect and the stress buffering effect of social support on the psychosocial well-being and the practical implications in developing service strategies for the unemployed. Three-hundred-Sixty-nine(369) unemployed people in Choong-ju City and surrounding areas participated to the study. The results showed that both main and direct effects were partially supported by the data. In exploring the direct effect, social support from the family showed the strongest positive effect on the well-being of the unemployed. In the test of the stress buffering effect, the results showed a marginal buffering role of social support against the negative impacts of stress. Drawn from the results, the needs for further research in investigating the social support theory were suggested and possible implications for developing social work intervention strategies for the unemployed were identified.

  • In this study, we investigated the buffering effect with different COD, $NH_4{^+}-N$ and TP shock loads on the performance of lab-scale Sequencing Batch Reactor(SBR) using synthetic wastewater. This study was operated under the following conditions : HRT, 12 hrs : MLSS, 2,000 mg/L : F/M ratio, $0.2kgCOD/kgMLSS{\cdot}d$ : SRT, 20days, and was increased by a factor, COD : ranging from 200-2000 mg/L, $NH_4{^+}-N$ : ranging from 30-300 mg/L, T-P : ranging from 5-50 mg/L in the reactor. As results, COD removal rate at different shock loads was decreased until 42.1%(stable state : 95%) and concentration with effluent was higher than 695 mg/L(at Run 6). In case of $NH_4{^+}-N$ removal rate was decreased until 35.8% from 97.0% and also T-P removal rate was decreased until 5.0%. Effluent concentrations of COD, $NH_4{^+}-N$ and T-P were rapidly increased according to shock loads and needed 3, 4 and 6 additional cycle times for recovering the stable condition.

  • The purpose of this study is to understand the effect of violence in sports on intention to sport continuance among female athletes and to analysis the mediating effect of depression and the difference groups according to help-seeking. In order to accomplish these purposes, this study surveyed from September to October in 2010. The final subjects in the analysis were 345 female athletes who are belong to school athletic team, professional team, business team, and national team. The data were analyzed with SPSS 18.0 and AMOS 10.0 for conducting multiple group analysis. The main results of this study are as follows; First, those who were suffered by emotional violence were 62.4%; those who are damaged by physical violence were 28.6% among the participants in this study. In case of intention to sport continuance, when measured by a rule of five, was average 3.15. 29.9% of the female athletes scored above the standard of depression. Second, depression turned out to have a partial mediating effect within the relationship where violence in sports has effect on intention to sport continuance. Third, between experimental and non-experimental group on help-seeking among female athletes, there was a statistically significant difference in the structural relationship. This means that help-seeking has moderating effect within the path of violence in sports affecting depression. Based on the results, this study suggested that there is a strong need for intervention for the both prevention and cure of the sports violence. It is necessary to develop preventive programs and coping strategies on female athletes' depression and intention to sport continuance.

  • This study is to analyze the existence of the real buffer effect that reflects the effect of beginning-of-period inventory stocks effect on the demand for fixed investment, and the financial buffer effect indicates the substitution effect between end-of-period inventory stock and the source of financing for fixed investment. I use panel data of 361 Korean listed non-financial firms during 1990-2003. After the crisis, it also observed whether the relationship between inventory stocks and fixed investment has altered or not. I review the theoretical connection between inventory stock and fixed investment through the paper by Bo(2004) and estimate the investment model by the method of GMM-SYS. The results show negative relation between end-of-period inventory stock and fixed investment in the whole period and each period classified, also it confirms that the relation between fixed investment and end-of-period investment is significantly negative. It can be interpreted through two aspects that firms not only use inventory stock as a buffer in response to unexpectedly high demand, but also utilize inventory stock as a source of financing for fixed investment. The results imply that firm's decision-making is much correlated with production-and-inventory stock adjustment, decision-making about fixed investment, and decision-making about financial affairs.

  • A column study using artificial acid rain was conducted to evaluate the buffering capacities in soil layer and host rock. In an effort to compare the effect of composition of host root two valleys of which compositions of host rock are different were chosen within the study area and the pHs of the water flowing in the valleys were measured from May, 1996 to October, 1996. The pHs of the artificial acid rain prepared by adding appropriate amounts of both sulfuric and nitric acids to distilled water were 3, 4, and 5, and the column effluents were analyzed for major cations and anions. The cation exchange capacities(CECs) of A Horizon and the B Horizon were 9.68 and 6.16 meq/100g, respectively, Compared to the B Horizon, the pH in the column effluent of A Horizon with larger CEC was higher. The sums of $Ca^{2+}$, $Mg^{2+}$, $Na^{+}$in the column effluents gradually decreased, indicating the loss of CEC by acid rain. The field study showed that pHs of the surface water in the valleys increased as the water flows downwards. The magnitude of this buffering capacity was greater for the valley in which smectite in addition to kaolinite and illite was a weathered product of host rocks. This also indicates that host rock as well as soil layer retains the buffering capacity.

  • In anti-ship missile, the seeker and guidance control units are located in front of warhead. When the missile hits target, these structures play an important role to warhead structure like a shock absorber Because the shock waves are attenuated, the survival probability of warhead increases which guarantees the explosive train. In this thesis the role of frontal sections is studies. The theoretical analysis and numerical analyses using LS-DYNA code are performed. To prove the effect of shock absorber, the penetration test using subscale prototype warhead are executed.
