Class has been the factor that affects welfare attitudes in western societies. But the results of the studies on affects of class in Korea are not consistent. This Study focuses on the relations between three class variables-income, status in employment, occupation-and the Korean attitudes on welfare policy and examines the regulating effects of education on that. Attitudes on welfare policy consist of 'reinforcement of established welfare programs', 'expansion into new welfare area' and 'universalism in welfare policy.' The result shows that all three class variables, education and age do not affect the attitudes to 'reinforcement of established welfare programs.' Age and class variables affects the attitudes to 'expansion into new welfare area' statistically, but education does not. Education explains largest parts of the attitudes to 'universalism in welfare policy.'

A systemic review on the factors affecting food catering hygiene was conducted to provide information for risk management of food catering in Korea. In total 47 keywords relating to food catering and food hygiene were searched for published journals in the DBpia for the last decade (2005-2014). As a result, 1,178 published papers were searched and 142 articles were collected by the expert review. To find the major factors affecting food catering and microbial safety, an analysis based on organization and stakeholder were conducted. School catering (64 papers) was a major target rather than industry (5 pagers) or hospitals (3 papers) in the selected articles. The factors affecting school catering were "system/facility/equipment (15 papers)", "hygiene education (12 papers)", "production/delivery company (6 papers)", food materials (4 papers)" and "any combination of the above factors (9 papers)". The major problems are follow. 1) The problems of "system/facility/equipment" were improper space division/separation, lack of mass cooking utensil, lack of hygiene control equipment, difficulty in temperature and humidity control, and lack of cooperation in the HACCP team (dietitian's position), poor hygienic classroom in the case of class dining (students'), hard workload/intensity of labor, poor condition of cook's safety (cook's) and lack of parents' monitoring activity (parents'). 2) The problem of "hygiene education' were related to formal and perfunctory hygiene education, lack of HACCP education, lack of compliance of hygiene practice (cook's), lack of personal hygiene education and little effect of education (students'). 3) The problems of "production/delivery company" were related to hygiene of delivery truck and temperature control, hygiene of employee in the supplying company and control of non-accredited HACCP company. 4) The area of "food materials" cited were distrust of safety regarding to raw materials, fresh cut produces, and pre-treated food materials. 5) In addition, job stability/the salary can affect the occupational satisfaction and job commitment. And job stress can affect the performance and the hygiene practice. It is necessary for the government to allocate budget for facility and equipment, conduct field survey, improve hygiene training program and inspection, prepare certification system, improve working condition of employees, and introducing hygiene and layout consulting by experts. The results from this study can be used to prepare education programs and develop technology for improving food catering hygiene and providing information.

Naringin, major citrus flavonoids, has been identified to exert antioxidative, antidiabetic, and lipid lowering effects. In this study, we examined the effect of 0.2 g/kg, 0.5 g/kg naringin supplementation for 3 times/week for 5 weeks on lipid metabolism and antithrombotic capacity in rat. Eighteen five week-old Sprague Dawley(SD) female rats, which had initial body weights of $246{\pm}9g$, were randomly divided into three groups: Control (non naringin group); Low (0.2 g/kg naringin-supplemented group); High (0.5 g/kg naringin-supplemented group). Three groups of rats were supplemented with three experimental diets for 5 weeks and we investigated antithrombotic capacity before sacrifice. Naringin did not significantly alter the body weight gain, relative organ weight. However, the level of serum triglyceride, serum free fatty acid, serum total lipid and serum glucose levels were significantly lowered compared to those of control. The high group (0.5 g/kg naringin-supplemented group) was showed significantly increased bleeding time compared to control group. These results suggest that naringin supplemental diets reduces the level of hypertension, glycosuria and fatness on the female SD rats, when orally administered below the dosage 0.5 g/kg for 5 weeks.

While small and medium-sized companies are suffering from a shortage of workers as a result of social tendency to avoid those companies, college graduates still prefer large companies or governmental positions, which consequently results in inconsistencies in the demand and supply of work forces. The gap between them is getting so bad that employment difficulties are exacerbating. Accordingly this study tries to search for potential employee's expected value factors which make people select small and medium companies not big companies. A survey was conducted from October 1 to october 30, 2012 with university students in the Seoul metropolitan area. a total of 350 questionnaires were distributed and 335 were collected. of these, 332 questionnaires were used for data analyses excluding questionnaires with missing values. Data was analyzed by frequency, descriptive factor, reliability, and regression with SPSS win 18.0 program The result of this study were as follows. A factor analysis extracted four factors comprising small and medium companies, which we named career(factor 1), working environment(factor 2), working achievement(factor 3), job security (factor 4). This study showed that small and medium companies' preference were affected by the career, working environment, job security, corporate reputation, salary.

Purpose: The purpose of this study is to analyze the impact of regional characteristics on population movement on the Seoul metropolitan areas. Method: To this end, 66 basic entities in the Seoul metropolitan area were divided into three regions by analyzing the demographic movement data from 2010 to 2016 and the factors for determining population movement within and between regions were identified by applying a stepwise regression technique. Result: The major analysis confirmed that the increase in the number of apartments in all areas of the Seoul metropolitan area, the increase in the number of single-family homes, the increase in the number of employees, the increase in manufacturers, the growth rate of knowledge, culture, and leisure industries, the increase rate of GRDP, and the opening of new subway stations. In particular, the growth rate of the number of apartments, the growth rate of the knowledge, culture and leisure industries, the increase rate of GRDP, and the opening of new subway stations played a positive role in increasing population inflow. Conclusion: The result showed that by region, the growth rate of knowledge, culture and leisure industries contributed greatly to the inflow of population in the first region, and that the opening of new subway stations and the increase of GRDPs were the main factors. The increase in the number of apartments and subway stations were the main factors in the three areas.

Purpose:Epilepsy of child may cause high level of psychosocial difficulties for parents including stigmatization and stress and therefore worsen their quality of life (QOL). The purpose of this study was to evaluate the mediating effect of perceived stigma against epilepsy on QOL among parents with epileptic child. Methods:Two hundred and sixty parents of epileptic child recruited from five separated university hospital child neurology clinics specializing in epilepsy completed a demographic questionnaire, a medical questionnaire, a perceived stigma questionnaire and the Ro's Quality of Life Inventory, a popular tool for evaluating QOL of adults in Korea which is composed of 6 domains and 47 questions. Data was analyzed with SPSS 14.0 program using frequency analysis and descriptive analysis and with AMOS 7.0 program using Structural Equation Model (SEM) analysis. Results:The level of parents' QOL was relatively fair. SEM analysis on the quality of life level of parents showed that all variables (especially having religion, the monthly income, employment state, age of child, the leisure time, the perceived stigma level against epilepsy, and seizure frequency) directly affect the quality of life level of parents and that disease-related variables also affect the quality of life level of parents indirectly through the mediating factor (the perceived stigma), where the indirect effect is large with the existence of combined disabilities. The total effect on the quality of life level of parents is large with the existence of combined disabilities, the perceived stigma level, the leisure time, having religion, and the monthly income. Conclusion:The results of this study indicated that many factors including parents' perceived stigma may affect the quality of life of parents with epileptic children directly, and that some disease-related factors may affect indirectly through a mediating factor, the perceived stigma. Multidisciplinary collaboration would be imperative for their welfare.

This study investigated the hepatoprotective effects of an ethanol extract of Petasites japonicus S. et. Z. Max. (PJ) on alcohol-induced liver-damaged rats. Sprague-Dawley rats weighing $100{\sim}150\;g$ were divided into 5 groups; normal diet group (NOR), alcohol (35%, 10 mL/kg/day) treated group (CON), PJ 200 mg/kg/day treated group (PJ1), PJ 200 mg/kg/day and alcohol treated group (PJ2), and PJ 400 mg/kg/day and alcohol treated group (PJ3). The growth rate of the control group was higher than that of normal group, whereas the group administered PJ concomitantly was significantly increased. Also, feed efficiency ratio decreased by alcohol administration was gradually increased to the adjacent level of the normal group by administering PJ. The AST activity in serum elevated by alcohol was significantly decreased by administering the high dosage of PJ, but exerted no significant change on serum ALT activity. It was also observed that the hepatic activities of catalase and GSH-Px increased by alcohol were markedly decreased in PJ2 and PJ3, but not in the activities of XO and SOD as compared with the control group. The depleted content of GSH by alcohol was increased to the level of normal group by administering PJ in a dose-dependant manner. In conclusion, these results suggest that PJ may have a possible protective effect on liver function in hepatotoxicity-induced rat by alcohol administration.
