This study was conducted to help develop women's human resources and promote married women's return to workforce. Using various data, we examined the patterns of Korean women's economic activities over the lifecycle, career discontinuation and return to the workforce. We also interviewed twenty full-time housewives who wanted to return to workforce. The interview questions included reasons for seeking employment, desired working conditions, and difficulties in finding a job. Major findings are as follows: First, there were two groups with respect to reasons why they want employment One was an economic need such as earning basic living expenses and supporting the family. The other was self-realization and social participation. Second most women wanted to do unskilled labor such as housekeeping work, whereas some young or well-educated women looked for a professional job. Third, married women preferred part-time jobs, which were compatible with their family care demands. Most of them wanted a workplace located close to home. The women with child-care responsibility preferred working at home. Fourth, regarding difficulties of returning to workforce, they pointed out vocational ability problems due to their career discontinuation, social prejudice such as gender discrimination and psychological pressure in maintaining work and family at the same time. In order to promote employment of married women, it is required not only to change social prejudices but also to increase effectiveness in policy implementation. In addition, counseling for job-search and vocational ability training programs should be provide.

Hand washing is an important component of hygiene program for food handlers. Hands can be a source of direct or indirect contamination of foods with pathogenic microorganisms. In this study, the effectiveness of hand washing methods and the use of 70% alcohol solution against transient skin bacteria was tested in an university foodservice facility. 70% alcohol solution is sprayed for 5 seconds automatically when hands are placed in the dispenser. Samples were taken using swab technique in meat cutting area, vegetable trimming area, and vegetable cutting area: before and after washing hands according to planned methods, and after being sprayed with 70% alcohol solution after washing hands. The bacteriological analysis of total plate counts, coliform, fecal coliform of food handlers' hands was done. Statistical data analysis was completed with Mann-Whitney U test and Kruskal-Wallis model using the SPSS program. The levels of initial contamination of workers' hand were significantly different by the work areas($x^2$=9.156, p<0.01). Workers in the vegetable trimming area had more heavily soiled hands than in the other work areas. Mean of TPC counts and coliform was 8.97×$10^5$ CFU/12.4$cm^2$, 2.93×$10^2$ MPN/12.4$cm^2$ respectively, but fecal coliform was not detected. Transient bacteria were removed from hands after washing and using 70% alcohol solution but were not removed completely. Mean reduction percentage in TPC varied among work areas and ranged from 93.19% to 94.99%, and in coliforms from 97.31% to 100%. A significant difference in TPC was found between before and after hand disinfection (Z=-2.714, p<.01) and between standardized hand washing procedures and un-standardized hand washing procedures(z=-2.301, p<.01). Subjects using the hand sanitizer showed a great elimination of TPC(99.45% reduction), but this effect was valid only after following proper washing procedures. Based on the results, the most effective hand washing method was recommended as the combination of the standardized hand washing procedure with warm-water and use of the 70% alcohol solution. The results can be used to develop hand hygiene programs and training strategies for enhancing hand hygiene practices for food handlers in foodservice operations.

Purpose : The purpose of this study was to analyze the reaction of recovery for the fatigue by sports massage treatment after Taekwondo training and then to verify the effectiveness. Subject : The subjects of this study were all the 20 high school Taekwondo players divided into two groups (rest recovery group and sports massage group) selected by systematic random assignment sampling. Method : The variables were the level of hemoglobin, lactic acid and glucose, and measured at rest, immediately-after exercise and 30-minute recovery. The data from this study were analyzed by using one-way ANOVA, independent sample t-test. Results : The results are as follows ; 1. The measurement of the hemoglobin, there was not the significant differences between experiment group and control group. 2. The lactate showed lower in the experiment group than in the control group in 30-minute recovery (p<.001). 3. The glucose showed lower in the experiment group than in the control group in 30-minute recovery (p<.01). So I think the sports massage treatment is more effective in the relief of fatigue than static rest method during the recovery after sports. However the massage treatment influence on the activation of metabolism according to the intensity and the duration of sports, and vary the effect of treatment according to the method and execution time. Therefore the longitudinal investigation of the variation by the long time massage through the more detailed program must be requisite for us.
