  • 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 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.

  • This study was carried out to investigate the effect of vegetative buffer to reduce runoff and soil and nutrient loss at highland agricultural area. The soil of experimental field was classified as Ungyo series (Fine, Humic Hapludults). An area of each field with lysimeter was $50m^2(width\;2.5m{\times}length\;20m)$ and was a gradient of 17%. Chinese cabbage (Brassica campestris L.) was cultivated by general management in each field. For establishing vegetative buffer, rye (Secalecereale L.), tall fescue (Festucaarundinacea Schreb) and orchard grass (Dactylis glomerata L.) were planted at the edge of field. Rye buffers were 1m, 2m and 4m wide. Both orchard grass and tall fescue buffers were 2m wide. Vegetative buffers were set up in September 2005 and chinese cabbage was planted in June 2006. Soil loss, runoff and nutrient loss were measured from June to August in 2006. Since the precipitation amount was heavy in July, amounts of runoff, soil erosion and nutrient loss were the highest in July during this study period. In comparison with control, vegetative buffers of rye 2m, orchard grass 2m and tall fescue 2m reduced runoff by 3%, 1% and 2%, respectively. In comparison among width of rye buffer, rye 1m, rye 2m, and rye 4m reduced by 1%, 4% and 13%, respectively. Vegetative buffers of rye 2m, orchard grass 2m and tall fescue 2m showed the reducing of soil loss by 59%, 46% and 28%, respectively. In comparison among width of rye buffer, the highest reducing effect of 88% was observed in 4m treatment. Additionally, vegetative buffer reduced N, P and K losses in runoff and eroded soil which were 10 to 54%, 7 to 24% and 11 to 21%, respectively. In different widths, wider vegetative buffer showed lower loss of N, P and K in runoff and eroded soil. As a result of this study, the vegetative buffer of rye was most effective for reducing runoff and soil loss in comparisons with other plants. In addition, wider range of buffers recommended for reducing runoff and soil loss, if possible.

  • This paper was carried out to investigate the relation of pH, aciidity and sourness during Kimchi fermentation and preservatives on Kimchi fermentation. Na-acetate, Na-malate, K-sorbate and K-sorbate+acetic acid were added to Kimchi samples. These Kimchi samples were fomented for 7 days at $37^{\circ}C$ and $20^{\circ}C$. In the experiment about the sourness and buffer action by organic salts which showed that the intensity of sourness was differented by the difference of pH in the same acidity. Na-acetate (0.3%) and Na-malate (0.3%) acted as good buffer, whereas K-sorbate (0.1%) and K-sorbate (0.1%)+acetic acid (0.05%) acted as lactobacilli growth enhancer in the fermentation.

  • 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.

  • An objective of this study was to provide database for the planting disign of buffer green space. Types, planting structure, and effect of vuffer green space were investigated in five housing complexes of newtown of metropolitan area, Korea. Buffer green space in the study sites were constructed as mounding, slope, and plate. The number of species was found 20 tree and sub-tree species(10 evergreen and 20 deciduous species ) and 13 shrub species. These species were planted in one-storyed planting structure and there was no difference with ornamental species in the urban parks. Effect of sound proof by the buffer green space was recognized but sound level in four types among the seven types was observed above standard sound level for housing complex(65dB). Effect of sound proof was especially most effective in the mounding type. It was found that planting density and index of plant crown volume were mot satisfied to the function of buffer green space because of lower density and crown volume than natural vegetation per unit. Based on these results, this study suggested that buffer green space is desirable to be developed in the mounding type over two meters height with multi-layer planting model. In addition, there is needed to consider vegetation structure of natural forest around the developing site.

  • 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 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.

  • The purpose of this study is to examine the moderating effects of protective factors on the relations between deviant peer's influences and delinquent behaviors in adolescence. To investigate the moderating effects, simple slope and region of significance test based on multiple linear regression(MLR) model were used. This study used data from wave 1-2(2003-2004) of the Korea Youth Panel Survey(KYPS). Results showed that for female adolescents, self-esteem, parent monitoring, and attachment to parent moderated the link between best friend's deviancy and delinquent behaviors. For male adolescents, however, best friend's deviancy and protective factors didn't show any significant moderating effects. These results help clarify the conditions under which exposure to deviant best friends can influence delinquent behaviors in adolescence. Practice and policy implications as well as further research topic were discussed to aid the search for highly effective preventive and treatment interventions.
