In general, grandparents have been very influential resource persons on their grandchildren's gross development. Nevertheless it has been difficult to find many empirical studies that focused on the specific competence of grandchildren and showed strong evidence in its regard. Therefore this study was intented to investigate the influence of grandparents' social support on their grandchildren's social competence in the light of grandparent's social support on their grandchildren's social competence in the light of grandchildren-grandparent relationship. The subjects were 230 fifth grade children in elementary school who were 123 boys and 107 girls. Among them, 94 children were related with grandfathers, 167 children with grandmothers 101 children with maternal grandfathers and 182 children with maternal grandmothers. The questionaire was used as a methodological instrument and the statistics such as frequency, percentile, mean, Pearson's correlation, One-Way ANOVA and Scheff test were used for data analysis. The findings were as follows : 1) Children's affectional intimacy to grandparent was positively correlated with perceived grandparent's social support. 2) Perceived grandparent's social support was affirmatively correlated with grandparent-mother relationship, that is, grandchildren-grandparent relationship was mediated by mother. And 3) children who more perceived grandparent's social support than less perceived grandparent's social support were highly rated I social competence by teacher. In the result, children emotionally, informatively and instrumentally supported by paternal or maternal grandparents showed high social competence defined supported by paternal or maternal grandparents showed high social competence defined as interpersonal relationship ability on the significant level respectively.

This study focuses on green human resources management (GHRM), which is currently a strategic issue in almost every service or manufacturing company, including courier service SMEs in Indonesia. This study intends to analyze the relationship between GHRM and supply chain organizational learning (SCOL), supply chain performance (SCP), and business performance (BP) still rarely studied. The population encompasses all courier service SMEs in the Special Province of Yogyakarta (DIY) and East Java, Indonesia. The study targets courier service SMEs that meet certain conditions; 130 SMEs responded from the target of 200 SMEs. Partial Least Square statistical technique is used. The results show that conventional HRM practices are increasingly being abandoned by courier companies in Indonesia, particularly in Special Province of Yogyakarta and East Java. Although GHRM has a negative and non-significant effect on BP, GHRM has a positive effect on SCOL and SCP. SCOL has a significant positive effect on SCP and BP. Furthermore, SCOL mediates the relationship between GHRM and SCP and SCOL mediates the relationship between GHRM and BP. Likewise, SCP has a positive effect on BP. In addition, SCP mediates the relationship between GHRM and BP. SCP also mediates the relationship between SCOL and BP.

This study aims to investigate the impact of workplace safety on doctors' retention and turnover intention along with job satisfaction as the mediator. A questionnaire-based survey was conducted with 394 medical doctors working in thirty-five hospitals in Pakistan using a structural equation modeling. Results of the study showed that: 1) workplace safety has a significant positive relationship with employee retention; 2) workplace safety has a significant negative relationship with turnover intention; 3) workplace safety has a significant positive relationship with job satisfaction; 4) job satisfaction has a significant positive relationship with employee retention; 5) job satisfaction has a significant positive relationship with turnover intentions; 6) job satisfaction mediates between workplace safety and employee retention; while 7) job satisfaction failed to mediate between workplace safety and turnover intentions. The findings of the study suggest that in a fear-free and safe environment, employees' chance to stay will increases. The study also suggests that dissatisfied employees do not need to leave the organization. There can be other factors that can be explored in future studies. This study also provides a practical implication for the doctors' low retention and high turnover, specifically in the healthcare sector of Pakistan by providing guidelines to the human resource executives to focus on the strategic implementation of workplace safety.

Purpose - This study analyzes the effect of the authorized economic operator-mutual recognition arrangement (AEO-MRA) on the performance of Korean exporters and importers. The effect of the import-export companies' characteristics, such as annual sales, the number of foreign markets, and overseas experience, on the AEO-MRA is deduced; the relationship between this effect and firm performance is analyzed. Design/methodology - An empirical research model was constructed and analyzed using structural equation modeling. The effect of AEO-MRA on logistics and operational performance was derived from the aforementioned characteristics as leading factors of the AEO-MRA. The regulatory influence of cooperation with logistics companies was analyzed in the AEO-MRA effect on logistics performance. Thus, 172 valid samples were obtained from import-export companies certified by the AEO-MRA. Findings - Among the aforementioned characteristics, only "annual sales" has a positive effect on the AEO-MRA, whose effect enhances logistics and operational performances. The AEO-MRA effect did not directly affect operational performance. Owing to the adjustment effect analysis, the AEO-MRA effect and logistics performance relationship is strengthened if the cooperative relationship with the logistics company is higher than a certain level. If this cooperation falls below a certain level, the AEO-MRA effect on logistics performance reduces. Thus, logistics cooperation is an important factor in the AEO-MRA effect and logistics performance relationship. Originality/value - Hinging on the resource-based theory and relational viewpoint, an empirical model that explains the relationship between the AEO-MRA effect and firm performance is established.

The purpose of this work is to explore different types of intergenerational relationships in the later lives of old retirees. This will be done according to the eligibility of public pension and the old age social security system so that the factors affecting intergenerational relationships can be analyzed, and to propose a plan to improve social adaptation in later life. The data used in this work are the Fourth basic survey data of the 2011 Korea Retirement and Income Study. The study subjects of this work were 2,435 retirees over age 65 who had children. In this study, latent class analysis and logistic regression analysis were conducted to classify types of intergenerational relationships and to analyze the influence of relevant factors. As a result of the analysis, some of those in the group were eligible for public pension, and the ones who were not were classified into three types: the closely-living-together type, the separate-living-contact type, and the estrangement type. In the group not eligible for public pension, it was found that age, spouse, number of children, economic factors, and level of health satisfaction gave significant power to intergenerational relationships. In the group eligible for public pension, it was found that age, income and net assets, ADL(Activities of Daily Living), whether there was an IADL(Instrumental Activities of Daily Living) spouse, and number of children affected types of intergenerational relationships; Socio-demographic factors, economic factors, and healthy factors became significant variables according to the classified types of intergenerational relationship. Based on the study results, this work suggested such necessities to lay the foundation for an elderly welfare system for social adaptation in later life, This includes the offering of programs for retirement preparation, the use of family and local society resources, and expansion of the opportunity to participate in social activities.

This study examined the mediating effects of couple communication on self-differentiation and marital satisfaction among married women. The ANOVA, correlation and the multiple regression analysis were used to figure out the relationships and the mediating effects of those variables. The results revealed that self-differentiation was significantly related to marital satisfaction. Also, couple communication was revealed to be a partial and full mediator between self-differentiation and marital satisfaction. The results were as follows. First, there were differences in couple communication and marital satisfaction. Marital satisfaction showed differences according to socio-economic variables such as educational level, occupation, family income, and the years of married life. Educational level and family income made differences in couple's communication. However, socio-economic variables did not make any difference with regard to self-differentiation. Second, there was a significant correlation among all sub-factors for self-differentiation, whole self-differentiation, married couples' communication, and marital satisfaction. Third, the result shows that the mediating effect of couple communication between self-differentiation and marital satisfaction. Couple communication completely mediated the relationship between cognitive vs. emotional function, family projection, emotional cutoff, and marital satisfaction. It also partially mediated the relationship between family regression and marital satisfaction. In addition, there was a tendency to partially mediate the relationship between general self-differentiation and marital satisfaction. The results suggested that self-differentiation and couples communication should be considered together when explaining marital satisfaction among married women. Also, the results implied the importance of the increased self-differentiation and the better couple communication in women's marital satisfaction. Finally, this research suggested the necessity of counseling services to enhance the self-differentiation as well as couple communication programs for the marital satisfaction of women.

The purpose of this study is to analyze the potential soil loss and hazard zone by the Revised Universal Soil Loss Equation(RUSLE) for preservation and management of land resources which is the base of ecosystem, and to grasp the relationship between RUSLE factors in the Nakdong River Basin. All thematic maps used in RUSLE are constructed through GIS and spatial analysis method derived from digital topographic maps, detailed soil maps, land-cover maps, and mean annual precipitation of 30 years collected respectively from National Geographic Information Institute, National Institute of Agricultural Science and Technology, and Ministry of Environment. The slope length of LS-factor that takes much times by the study area's wideness was calculated automatically through AML(Arc Macro Language) program developed by Van Remortel et al.(2001, 2003). The results are as follows; First, according to the soil loss estimation by the RUSLE, it shows that approximately 82% of the study area have relatively lower possibility of soil loss which is the 1 ton/ha in annual soil loss. While, 9.4% ($2,228km^2$) needed intensive and continuous management for soil loss. Because the amount of their annual soil loss was greater than 10 ton/ha that is optimum level suggested by Morgan(1995). For these areas, the author believe that a new approach which can minimize environmental impacts from soil loss through improvement of cultivation process and buffer forest zone should be applied. Second, according to the relationship between the RUSLE factors, topographical(LS-factor) and cover management(C-factor) conditions have a lot of influence on soil loss in case of the Nakdong River Basin. However, because of RUSLE factor's influence that affect to soil loss might be different based on the variety of spatial hierarchy and extent, it is necessary to analyze and evaluate factor's relationship in terms of spatial hierarchy and extent through field observations and further studies.
