This study examined the effects of the revised and newly established family care leave and vacation systems in 2019 on the work-family balance of female managers. A total of 1,040 female managers with experience in using the systems were selected as the analysis subjects from the 2020 Women Managers Panel data. Propensity score matching and multiple regression analysis were conducted. The propensity score matching results showed that the family care time of the users of the family care leave was significantly lower than that of non-users, and both the work-family conflict and home-work conflict levels were significantly higher for the users than the non-users. For the family care vacation, the family care time of its users was significantly higher in national and local government organizations than that if its non-users. The results of multiple regression analysis indicated that the use of the family care leave had a significant positive impact on home-work conflict. These findings suggest that the current family care leave and vacation system have insufficient positive effects on work-family relationships.

This study is focused on the job condition, the morale and the job leave of the private security. The private security industry in korea has been grown rapidly in its quantity, but the quality is not followed with it. So The reality on the private security Industry is in the low income and the negative morale, and it leads to leave the job openly. The job leave and the morale of the private security depend on the given job condition. Therefore to improve their job satisfaction and job condition the related parties should have concerned the quality for them. Because the output of their job performance depends on the private security's job morale, In this point of view the morale in the job and job leave have very relationship. The survey on the job condition, the morale and the job leave of the private security has the followings; 1) The male is more unsatisfied than the female in their job condition, and the female is more satisfied than the male in their income. 2) The male is more higher than the female in job leave intention, especially 20s are most higher and 40s are most less. 3) The positive morale in the private security would be grown if the income and job satisfaction would be made in certain level and the fair promotion would be promised. 4) To improve the stability and effectiveness in the private security system the rate of job leave should be reduced and the proper job would be distributed.

Machine vision system was used for analyzing leaf color disorders of tomato plants in a greenhouse. From the day when a few leave of tomato plants had started to wither, a series of images were captured by 4 times during 14 days. Among several color image spaces, Saturation frame in HSI color space was adequate to eliminate a background and Hue frame was good to detect infected disease area and tomato fruits. The processed image ($G{\sqcup}b^*$ image) by OR operation between G frame in RGB color space and $b^*$ frame in $La^*b^*$ color space was useful for image segmentation of a plant canopy area. This study calculated a ratio of the infected area to the plant canopy and manually analyzed leaf color disorders through an image segmentation for Hue frame of a tomato plant image. For automatically analyzing plant leave disease, this study selected twenty-seven color patches on the calibration bars as the corresponding to leaf color disorders. These selected color patches could represent 97% of the infected area analyzed by the manual method. Using only ten color patches among twenty-seven ones could represent over 85% of the infected area. This paper showed a proposed machine vision system may be effective for evaluating various leaf color disorders of plants growing in a greenhouse.

A new binder system and debinding process for low carbon residue in the injection molding of Nd(Fe, Co)B powder are investigated. In the injection molding of magnetic materials, it is demanded to reduce carbon residue which deteriorates their magnetic properties. The binder system developed is composed of polyethylene glycols (PEGs) and polypropylene (PP). PEG was selected as a major binder is component to be extracted in a molecular state by solvent extraction in ethanol, which step would leave no residue. PP was selected as a minor binder component to be subsequently removed by thermolysis which step would leave carbon residue. The behaviors of solvent extraction with the variations of PEG molecular weight, temperature, and time were examined. The dependency of residual carbon content on thermolysis atmosphere was also studied. Opened pore channels introduced in a green body by the solvent extraction and microstructures of the sintered magnets were observed using SEM.

Objectives : The purpose of this study was to analyze the effect of welfare system of medical institutions on job satisfaction and organizational commitment of female workers. Methods : A survey was performed with 556 female workers of 11 general hospital and 7 acute period hospital in Busan. Data were collected from October to November 2017 with a self-report questionnaire and analyzed using SPSS 24.0. Results : Among those aged over 40 years, high awareness of obligatory welfare, job education, free use of the annual leave, and flexible working system was a positive factor in job satisfaction. Among managers, free use of the annual leave, job education, flexible working system and child-care facilities was a positive factor in organizational commitment. Conclusions : In medical institutions with a relatively high proportion of married women, although interest in welfare for childbirth and child rearing is high, execution is sluggish, hence, policy support of government and medical institutions in this field is necessary.

In 2019, the Seoul metropolitan government established its own 'Seoul-type paid sick leave project'. Although the central government had to introduce such a system, which is also called sickness benefits, it was not implemented. In order to understand the process by which the Seoul government has implemented such a policy, this study used Kingdon's multiple streams framework. As a result, in the problem stream, it was found that the economic burden of sickness has been considered only in terms of medical expenses in the past of Korea. Then Songpa's three women and Middle East respiratory syndrome incidents raised awareness of the necessity of the sickness benefit system in 2014 and 2015. In the political stream, several social affairs such as national health insurance huge surpluses and the 2017 presidential election opened policy window. At that time, Seoul Mayor actively promoted sickness benefits as a policy entrepreneur. In the policy stream, the sickness benefit system has gained new attention through political events. To summary, these three streams flowed separately and then they assembled around huge political affairs. As a result, it was confirmed that Kingdon's model is the most effective theory than any other models in analyzing the health care policy decision process in Korea.

This study analyzes the effects of women's labour force participation and work-family reconciliation support on life-cycle fertility in Korea. The analysis is based on the longitudinal data from Korean Labour and Income Panel Study (KLIPS), which include the available information on life-cycle fertility and employment history. Employing a dynamic model of fertility, we estimated the life-cycle fertility of all the 15-49 years old women considered in this study by using a duration model. The major results of this study were as follows: First, women's labour force participation had a negative effect on the first birth, second birth, and all births (transition to births starting at different parities). Women's employment tended to lengthen the interval between births. Second, the availability of maternal leave had a positive effect on the first birth and all births for working women. Providing maternal leave to working women decreased the opportunity cost of childbearing and in turn, reduced the interbirth interval of women. However, the availability of parental leave had no significant effect on the births of working women. Third, the financial support for childcare had a positive effect on the first birth and all births. The economic support for childcare led to the reduction in the interbirth interval of women by increasing the probability of births. The use of a childcare center for the first child, which substitutes for the time that women needed to take care of their children, classified as time-intensive consumption goods, did not have any effect on the second birth. Fourth, the part-time employment of women had a positive effect on the second birth. A flexible working time schedule tended to decrease the interval between the first and the second births.
