Recently, with increasing interest in the subject of interfirm relationship mechanism, some information systems researchers point out that existing outsourcing theories are limited in explaining the choice of governance mechanisms in interfirm relational exchanges. Recognizing the importance of trust-commitment, this study focuses on the relationship of between control mechanism and commitment. Especially the role of trust as mediator is mainly researched. A mediation model was suggested on the basis of theoretical linkages from prior relevant studies. The research model was empirically tested with 73 IS outsourcing projects. The findings have significant impactions for further research and practice. Findings are as follows: First, outcome control, process control, social control had positive effects on trust and commitment. Second, inter-organizational trust played as a partial mediator on the relationship between control mechanisms and commitment. Based on these findings, the implication and the limitation of the study were presented including some directions for future studies.

The purpose of the present study was to investigate the longitudinal relationship between main caregivers' life satisfaction and depression and self-esteem of school-aged children, and to provide plans for improving the lives of the school-aged children. For this purpose, we analyzed the three years'longitudinal panel data (2011-2013) of the Korean Children and Youth Panel Survey (KCYPS) including 2,342 first grade elementary school children employing the latent growth model using SPSS 18.0 and AMOS 22.0. Analysis results were as follows. First, main caregivers'life satisfaction and school-aged children's depression increased as time passes and linear change model was selected. Second, the initial status of main caregivers'life satisfaction had effects on the initial status of their children's depression, but initial status and rates of change of life satisfaction did not have an influence on the rates of change of the depression. However, it was found that the main caregivers' life satisfaction had effects on the school-aged children's self-esteem and it worked as a mediator on the longitudinal relationship between the main caregivers'life satisfaction and the children's depression. School-aged children's self-esteem was a partial mediator on the initial status of their depression and full mediator on these rates of change. These findings suggests that programs improving school-aged children's self-esteem should be developed.

The objective of the present study was to test the effect of platelet-activating factor (PAF) on rat alveolar macrophages. PAF alone did not stimulate superoxide secretion from alveolar macrophages. However, PAF $(10^{-5}\;M)$ significantly enhanced phagocytic activator zymosan-induced superoxide secretion from alveolar macrophages. This enhancement of PAF plus zymosan was 30% above the sum of the separate effects of PAF and zymosan. Similarly, PAF $1.3{\times}(10^{-5}\;M)$ was not a direct stimulant of alveolar macrophages, as it had no stimulatory effect on chemiluminescence generation, but potentiated zymosan-induced activation of chemiluminescence, i.e., 162% above the separate effects of each stimulant. PAF $10^{-16}{\pm}10^{-6}\;M$ also failed to stimulate IL-1 production from alveolar macrophages. In contrast, when both PAF $10^{-10}\;M$ and lipopolysaccharide(LPS) $(1 {\mu}g/ml)$ were added together at the initiation of the culture, IL-1 production was significantly increased indicating the potentiative effects of PAF on IL-1 production by alveolar macrophages. Collectively, these data suggest that PAF alone does not activate the release of bioactive products from alveolar macrophages. However, PAF appears to act as a priming mediator that potentiates stimuli-induced macrophage activity. These novel actions of PAF prove its role as a potent mediator of inflammatory and immune responses in the lung.

The purpose of this study is to analyse the effect of information application of the elderly on their lives through analysing the key papers on the topic. To achieve the aim of this study, we searched the papers from RISS, KISS, DBpia and the National Assembly Library of the Republic of Korea, using keywords such as 'the elderly and informationization,' 'the elderly and information application,' and 'mediator effect.' In the search process, we did not limited the publication year or journal types. A total of 476 papers were searched as the result of the initial search. Based on three researchers consent of selection criteria, we finally selected 19 papers and analysed the important mediator variables between the information application and the life satisfaction or happiness. Using the content analysis, we analysed the quantitative analyses (including sample characteristics and sociodemographic statistics) and qualitative analyses (including result interpretation and policy implication about the elderly information education). After in-depth analysis of the papers, we built a table organized by the independent variable and the mediator variable. With the results, several implications were discussed and contributions are also explained.

The purpose of this study is to examine depression in adulthood caused by the influence of negative life events (disaster accident, physical violence and emotional abuse) in pre-adulthood and explore the mediator effect of interpersonal maladjustment. To carry out such task, 974 people who have had negative life event experiences before the age of 18 were chosen based on the data from the 2012 Korean General Social Survey(KGSS) and Stata 10.0 was used to do the analysis. As a result, it was found that there was a direct relationship between negative life events in pre-adulthood and depression in adulthood. Specifically, experiences from an accident or disaster had a direct impact on depression. Moreover, experiences of physical violence and emotional abuse not only had a direct influence on depression, but also through maladjustment, it had an indirectly partial mediator effect that increases the chances of depression. Through this result, it was evident that negative life events from pre-adulthood had a negative effect on continuous interpersonal maladjustment as well as psychological welfare throughout the adulthood. Therefore, there needs to be thorough prevention measures on negative life events in pre-adulthood and strongly take post treatment into consideration. Through building a safe life environment, great deal of social support from social organizations should be prepared systematically.
