시간의 흐름에 따라 사회 구성원들에 대한 행태 연구나 사회의 변화가 개인의 행동양식에 미치는 영향 등에 대한 조사에서는 어느 한 시점에서의 구성원들에 대한 횡단면 조사와는 다르게 다년간 지속적으로 조사개체를 추적조사 해야 하는 종단면 조사 또는 패널조사를 수행해야 한다. 패널조사는 횡단면 조사와는 달리 최초 표본이 시간이 지남에 따라 조사 대상 표본으로부터 탈락함으로서 발생하는 표본의 마모와 그에 따른 대표성 상실의 문제이다. 그러므로 이러한 표본의 대표성 상실 문제를 적절히 해결하기 위해 적용 가능한 방법이 가중치 조정 방법이다 횡단면 조사에서는 (1)추출가중치의 조정, (2)무응답 가중치 조정, (3)사후층화 가중치 조정과 같이 3단계의 가중치 조정과정을 수행하지만, 패널 조사의 경우 이와 더불어 원 표본의 대표성을 유지하기 위해 종단면 가중치(longitudinal weight)를 함께 고려해야 한다. 이러한 관점에서 본 연구에서는 다양한 패널형태에 따른 가중치 조정 방법에 대해 고찰하고, 향후 수행될 한국복지패널(Korea Welfare Panel Study: KWPS)의 가중치 산정에 관한 이론적 근거를 마련함과 동시에 현재 국내에서 수행되고 있는 패널조사의 가중치 조정방법과 비교하고자 한다.

In this study, the impact of entrepreneurial orientation subfactors on organizational performance in the health and social welfare services industry was examined. Accordingly, responses from 272 organizations in this industry that participated in the corporate section of the 2022 Entrepreneurship Panel Survey conducted by the Korea Entrepreneurship Foundation were used. A regression analysis was performed on the data using the SPSS 25.0 program. According to the analysis, the entrepreneurial orientation subfactors of autonomy, proactiveness, innovativeness, and competitive pursuit had positive impacts on organizational performance. Risk-taking, on the other hand, had no effect on organizational performance. Based on these findings, building an entrepreneurial-oriented organizational culture and strengthening compensation to promote an entrepreneurial orientation are recommended.

This research attempts to calculate the vertical equity of National Health Insurance Contribution of locally provided policy holders by abilities to pay. Also, this longitudinal study examined the influence of abilities to pay and demographic characteristics on the health insurance premium. Using data from the Korea Welfare Panel Study, this study followed the self-employed households who continued to participate in the survey from 2011 to 2015. Kakwani's index of progressivity was measured as a measure of vertical equity and panel regression analysis was conducted by STATA program. The results of this research are as follows. First, from 2011 to 2015, the values of kakwani's index were negative according to composite income, which meant some levels of regressiveness of contribution. Secondly, panel regression analysis showed that the lowest household of composite income had a significantly negative effect on premiums, which also meant regressiveness. Based on the results, the author suggested political discussions on reorganizing the system of imposing the National Health Insurance contribution.

We compare various imputation methods for compensating wave nonresponse that are commonly adopted in many panel surveys. Unlike the cross-sectional survey, the panel survey is involved a time-effect in nonresponse in a sense that nonresponse may happen for some but not all waves. Thus, responses in neighboring waves can be used as powerful predictors for imputing wave nonresponse such as in longitudinal regression imputation, carry-over imputation, nearest neighborhood regression imputation and row-column imputation method. For comparison, we carry out a simulation study on a few income data from the Korean Welfare Panel Study based on two performance criteria: predictive accuracy and estimation accuracy. Our simulation shows that the ratio and row-column imputation methods are much more effective in terms of both criteria. Regression, longitudinal regression and carry-over imputation methods performed better in predictive accuracy, but less in estimation accuracy. On the other hand, nearest neighborhood, nearest neighbor regression and hot-deck imputation show higher performance in estimation accuracy but lower predictive accuracy. Finally, the mean imputation shows much lower performance in both criteria.

The purpose of this study is to investigate the effect of grandparenting on the grandparent's level of depression. In addition, it is to test the mediating effect of social support and the moderating effect of household type on the relationships between variables. The 555 grandparent sample in this study was from the Korean Longitudinal Study of Aging(KLoSA). The findings indicated that grandparenting(grandparenting time per day and total weeks of grandparenting per year) was significantly related to the grandparent's level of depression. In addition, the grandparent's age was also associated with grandparenting, grandparent's depression, and social support. Grandparent's health condition and marital status was associated with social support. Grandparent's gender had a significant relationship with grandparent's depression and grandparenting time per day. Social support had a direct effect to the grandparent's depression; however, it was not a statistically significant mediator between grandparenting and grandparent's depression. In addition, household type was not a significant moderator of measuring the relationships among grandparenting, grandparent's depression, and social support. Implications for social work practice were discussed based on the result of the study.

This paper is about the NOOMP(Not Out of My Pocket) phenomenon, the inconsistent welfare attitude for an expansion of welfare system and increase of financial resources. By analyzing the scale and influential factors of the NOOMP to the main welfare programs, focusing on the class, gender, and age group, the paper tries to investigate the relationship between the NOOMP and the inherent stratification structure of each programs. This paper uses the Additional Survey of Welfare Attitude in 2013 Korea Welfare Panel Survey. As a result of analysis, low level of NOOMP phenomenon has been observed in welfare programs for whole society members such as health policies, pension, employment policies, compared to those of targeted programs for the poor, aged, or disabled. In addition, high probability of each group of 'low incomer', 'female', and '20s or less'to the NOOMP phenomenon has been appeared, therefore, high relevance of the NOOMP and the stratification structure of welfare programs have been confirmed. These results indicate that the transition to the universal welfare programs and the improvement of welfare programs for more equal structure are needed to reduce the NOOMP phenomenon.

The purpose of this study is to examine the mediating effect of self-esteem on the effect of family relationship satisfaction on depression among the elderly and to draw implications for the social welfare field. For this study, raw data from the 16th Korean Welfare Panel Survey were used for analysis, and a sample of 4,310 elderly people aged 65 years or older was selected as respondents. The collected data were subjected to frequency analysis and correlation analysis using IBM SPSS 24.0, and the Process Macro of SPSS proposed by Hayes (2018) was used to examine the mediating effect. The results of the significance test of family relationship satisfaction on depression showed that family relationship satisfaction was significant, i.e., the higher the level of family relationship satisfaction, the lower the depression. In addition, the results of the significance test of the effects of family relationship satisfaction and self-esteem on depression showed that family relationship satisfaction had a significant effect, and the mediating variable, self-esteem, had a significant effect on depression. Therefore, this study aims to identify the characteristics of family relationship satisfaction among the elderly and provide policy suggestions and social work practice directions to reduce the level of depression among the elderly.

This study focuses on the following question; self-supporting training program increases participants' income compare to non-participants who have similar characteristics. This question is based on counterfactual assumption. In other words, this study concentrates on what the outcomes would have been if the participants were to be absent. This study adopts a quasi-experimental design. To overcome previous study's methodological weaknesses, especially selection bias, I applied matching procedure based on a propensity-score matching. Matching process was performed by using 'MatchIt' software. The major findings are as follows From Least Squares Regression analysis, I found the poor's income are significantly different according to age, pre-intervention earning, material status, and participation of training. Since the poor have homogeneous education level, education variable was not statistically significant. From the Simulation Quantities of Interest analysis, I also found that treatment group's expected incomes are lower than control's expected incomes. In other words, participation of training has a negative effect on the participants' earnings.
