Policy problems are complex due to diverse participants and their relations in the policy processes. Defining the right problem in the first place is important because Type III error is likely to happen without removing rival hypothesis in defining the problem. This study applies Boundary Analysis suggested by Dunn to structure IT policy problems in Korea. The time frame of the study focuses on 5 years of Lee Administration and data are collected from four newspapers. Using content analysis, the study, first, elaborates total 2,614 policy problems from 1,908 stakeholders. After removing duplicating problems, 369 problems from 323 stakeholders are identified as a boundary of IT policy problem. Among others, failures in government policies are weighted as the most serious problems in IT policy field. However, many significant problems raised by stakeholders dated back to more than a decade, and those are intrinsic problems, which initially caused by market distortions in the IT industry. Therefore, we should be cautious not to overemphasize the most conspicuous problem as the only problem in the policy field when we interpret results of problem structuring.

Objectives : The current treatment regimens for patients with nephrotic syndrome due to membranous nephropathy(MN) are based on steroids or immunosuppressive therapy with the aim of reducing proteinuria and improving outcome. Although these treatments attenuate the deterioration of renal function in MN patients, it has been suggested that all are burdened by significant toxicity. Therefore, more specific and less toxic therapies are needed. This study was to evaluate the effects of Coptidis Rhizoma Extract(CRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. One group named for 'Normal' was injected with a saline solution not to be immunized. The rest groups were treated as follows; After mice were immunized with 0.2 mg of cBSA and Freund's complete adjuvant one time every two weeks for 6 weeks, they received intra-peritoneal injection of 10 mg/kg of cBSA daily for 4 weeks. Also, they were divided into 3 groups. The first named for 'Control' was not given CRE. The second for 'CRE-250' was given oral administration of 250 mg/kg of CRE daily for 4 weeks. The third for 'CRE-500' was given 500 mg/kg of CRE. All of mice were sacrificed 4 weeks after the first immunization. We measured a body weight and 24hrs proteinuria as well as serological analysis. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria, triglyceride, IgG, IL-6 were significantly decreased in both CRE groups. And the level of IgM was significantly decreased in CRE-250 group. In histological findings of kidney tissue, thickening of GBM and deposition of electron-density were consideraly decreased in both CRE groups. Conclusions : The present study suggests that CRE is highly effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

The foodborne illness is the important public health concerns, and the livestock feces are known to be one of the major reservoirs of foodborne pathogens. Also, it was reported that 45.5% of foodborne illness outbreaks have been associated with the animal products contaminated with the livestock feces. In addition, it has been known that the persistence of a pathogens depends on many potential virulent factors including the various virulent genes. Therefore, the first step to understanding the public health risk of livestock feces is to identify and describe microbial communities and potential virulent genes that contribute to bacterial pathogenicity. We used the whole metagenome shotgun sequencing to evaluate the prevalence of foodborne pathogens and to characterize the virulence associated genes in pig and chicken feces. Our data showed that the relative abundance of potential foodborne pathogens, such as Bacillus cereus was higher in chickens than pigs at the species level while the relative abundance of foodborne pathogens including Campylobacter coli was only detected in pigs. Also, the microbial functional characteristics of livestock feces revealed that the gene families related to "Biofilm formation and quorum sensing" were highly enriched in pigs than chicken. Moreover, the variety of gene families associated with "Resistance to antibiotics and toxic compounds" were detected in both animals. These results will help us to prepare the scientific action plans to improve awareness and understanding of the public health risks of livestock feces.

The purpose of this study is to identify what factors actually affect the turnover intentions of social workers. It is an important task to grasp the factors of turnover of the social worker through empirical analysis because the high turnover rate of social welfare workers in Korea has a negative influence on their organization and ultimately impedes the stable delivery of social welfare services. This study used the results of analyzing 100 social workers in social service companies. In fact, the data used in this study were statistically analyzed only for 82 subjects, except for 18 subjects who did not respond to the variables used. As a result, the general effects of job stress on job turnover and job exhaustion were examined as much as possible. We examined the effect of job stress, an independent variable, on the turnover and exhaustion of social workers. Specifically, job stress was divided into role, organizational, and relationship, and it was found that role - related factor job stress only affected social workers' turnover intention significantly. In addition, the relationship-related affected the exhaustion of the social worker. Therefore, in order to reduce the exhaustion of the social worker, the desirable direction to reduce the stress of the relationship-related factor should be sought.
