Location-based services (LBS) are increasingly popular due to the improvement of geo-positioning capabilities and wireless communication technology. However, in order to enjoy LBS services, a user requesting a query must send his/her exact location to the LBS provider. Therefore, it is a key challenge to preserve user's privacy while providing LBS. To solve this problem, the existing method employs a 2PASS cloaking framework that not only hides the actual user location but also reduces bandwidth consumption. However, 2PASS does not fully guarantee the actual user privacy because it does not take the real user distribution into account. Hence, in this paper, we propose a nearest neighbor query processing algorithm that supports K-anonymity property based on the weighted adjacency graph(WAG). Our algorithm not only preserves the location of a user by guaranteeing k-anonymity in a query region, but also improves a bandwidth usage by reducing unnecessary search for a query result. We demonstrate from experimental results that our algorithm outperforms the existing one in terms of query processing time and bandwidth usage.

The aim of this study was to identify the utilization of health services and factors influencing the quality of life(QOL) of migrant workers. The participants were 135 migrant workers in Korea. Data was collected from September 10th 2012 to November 15th 2012. The data was analyzed using descriptive statistics, t-test, ANOVA, Scheff' test, and hierarchical multiple regression. Immigrant workers experienced difficulty in using health services and had a $14.25{\pm}2.01$ QOL, which was relatively low. The factors influencing QOL were the length of stay in Korea, residence areas, and satisfaction with health services. Final regression model accounted for 16.7% of the variance in QOL. The satisfaction level with health services was the most influential factors in the level of the QOL. Therefore, diverse strategies should be developed to enhance the satisfaction with health services in Korea migrant workers.

For the purpose of the study, the data were collected from 298 care workers by using non-random and purpose sampling method. The results of the study showed job environment was a significant predictor in explaining in the variances of care work appraisal and service quality. In addition, care worker's positive and negative appraisals of care work were statistically significant mediators in the association of between job environment and service quality. Finding of the study indicated that service quality could be improved by not only improving job environment but also strengthening care worker's positive appraisal of care work. Finally, based on the findings of the study, implications and limitations of the study were discussed.

The purpose of this study was to identify factors affecting quality of health care. Methods: The data were derived from the 2011-2013 Korea health panel survey (beta version 1.0). The data were analyzed using SPSS 21.0 with descriptive statistics, ${\chi}^2$-test, and multiple logistic regression analysis. In general characteristics, common factors influencing the quality of health care were age, marital status, education level, and subjective health status. In variables related to health care utilization, unmet healthcare needs, and limitation of dental care utilization were the significant factors affecting quality of health care. The results of this study show that various factors influence quality of health care. These findings can be used to develop strategies to improve health care.

This study aims to establish a research model to analyze the structural relationship between the working environment of the elderly medical welfare facility workers, the trust of the manager, and the quality of service. As a result, first, it was found that there was a significant causal relationship among service quality in the working environment of the elderly medical welfare facility workers. Second, it was found that there was a significant causal relationship between the working environment and the trust of managers of the elderly medical welfare facility workers. Therefore, in order to achieve the goal of the elderly medical welfare facility and improve the quality of service, it is necessary to create a working environment and establish a trust relationship among members.

This study was aimed at providing how to improve the service quality of home care workers, particularly through investigating their job stress and job satisfaction. Participants were randomly sampled persons who were living in P city and simultaneously serving as home care workers at the time of the study. This research conducted a self-reported questionnaire survey of them over one month of May 2021. Of collected data, responses from 130 of the participants were finally analyzing here using SPSS and PROCESS macro model 4. As a result, it was found that home care workers' job stress had no direct effect on their service quality, but had an indirect influence on it via job satisfaction. This means that the higher those workers are in job stress, the less they are in job satisfaction, ultimately having a negative impact on their service quality. Based on these findings, this study suggested some ways to raise home care workers' service quality.

This study was conducted with the purpose of verifying the effect of the working environment of elderly care workers on service quality and the mediating effect of emotional labor and recognition of filial piety. The subjects of the study were 460 elderly care workers. For the collected data, SPSS Process macro was used. As a result, First, it was found that all variables had a significant positive (+) relationship. Second, the parallel mediating effect of emotional labor and recognition of filial piety was confirmed. Third, the mediating effect of recognition of filial piety and the moderating effect of emotional labor were verified. Based on this study, it was found that filial piety awareness education and emotional labor management are necessary. A follow-up study with a more expanded concept should be conducted.
