The present study was carried out to investigate the effects of career identity and social support on the career decision-making self-efficacy of women who have experienced career interruption. Furthermore, the aim was to seek effective measures for making a career decision for the successful re-employment of women with a break in their career. From March $3^{rd}$ to April $2^{nd}$, 2018, a survey was conducted targeting 380 career-interrupted, married women with age between 30-50 years and with work experience of more than six months. The selected subjects had received 1-9 months of beauty education from various vocational training institutes, beauty academies, and women's center in Seoul and Gyeonggi region. A total of 361 questionnaires were used for final analysis. The SPSS Program for data analysis, Cronbach's ${\alpha}$, exploratory factor analysis, factor analysis, frequency analysis, correlation analysis, and multiple regression analysis were employed for the study. The results of this study are as follows. It was apparent that the establishment of a career identity and social support could play important roles in creating a relation with new career decisions for re-employment. Thus, this study aims to provide basic data necessary for the successful career preparation in women with career interruption.

The self-employment can provide work time flexibility. Work time flexibility would be a critical factor for married females' labor supply considering allocation of their time to market work and household work. This study used the 1998 and 2000 Korea Labor and Income Panel Survey for the empirical analyses. Applying the bivariate probit model with partial observability, this study analyzed factors related to the choice of participation in labor market and choice of self-employment. Also, this study examined the effects of marriage and the presence of younger children on changes in decisions related to labor supply using the multinomial logit model: exit from the labor market, increasing and decreasing work hours. The presence of the younger children showed a significantly negative effect on the participation in labor market while positive, but insignificant, effect on self-employment. Compared with females working for others, self-employers without employees and unpaid family workers are less likely to exit labor market rather than increasing work hours. The self-employment would be a good alternative to evade females' career interruption and therefore to enhance the potential human resources.

A computational approach was developed to understand about the arc quenching process in a gas circuit breaker(GCB). This approach is a program to analyze the gas flow in the breaker. The arc is processed at the same time. The program was used the so-called FLIC method for gas analysis techniques. It was referenced that the arc is interpreted the 'a Simplified Enthalpy Flow Arc Model'. In order to validate about the results of the program, a Auto Puffer GCB was chosen as the test subject. Because, the breaker is the one that arc current is interrupted by using the arc heating. And also, the current interrupting capability can be obtained only owing to the positive utilization(auto puffer) of the clogging phenomenon, without other puffer actions. In this paper, it has been realized that the entire arc quenching process is computerized, which is based on the self-flow current interruption by the auto puffer action. This program, which was verified through experiments, produced good results.

The purpose of this study was to examine the career-interrupted lives of highly educated career-interrupted women. The participants were 11 women in their thirties who had graduated from university graduated and had a child. We collected the qualitative data using a focused group interview. The results of this study can be summarized as follows. First, in personal histories of the career-interrupted women, there were marriages and births, difficulties with child care, priority placed on the family, pressure to retire, and an absence of a layoff system related to births and child care. Second, with regard to their interrupted lives, while there was comfort and an absence of work-stress, there was child care stress, financial stress, anxiety due to career uncertainty, a loss of the social self, depression, emptiness, low self-esteem, dependence on husbands, regret, conflict in career choices, and envy of childcare support. Third, their reasons for seeking reemployment included the financial benefits, increased independence, self-realization in their job, hope for a stable job, self-management, and hope for a social network.

The design and development procedures of SF6 gas circuit breakers are still largely based on trial and error through testing although the development costs go higher every year. The computation cannot cover the testing satisfactorily because all the real processes arc not taken into account. But the knowledge of the arc behavior and the prediction of thermal plasmas inside SF6 interrupters by numerical simulations are more useful than those by experiments due to the difficulties to obtain physical quantities experimentally and the reduction of computational costs in recent years. In this paper, in order to get further information into the interruption process of a SF6 self-blast interrupter, which is based on the combination of thermal expansion and arc rotation, gas flow simulations with a CFD-arc modeling are performed during the whole switching process such as high-current period, pre-current zero period, and current-zero period. Through the complete work, the temperature of residual arcs as well as the breakdown index after current zero should be a good criterion to predict the dielectric capability of interrupters.

Purpose. The elderly with UI experienced urine leakage for a long time. The prevalence of UI has increased and it makes costly. Particularly, the elderly were reluctant to visit a hospital or a clinic for the reasons of modesty and poverty. To solve this problem, incontinence intervention programs should be provided at the elderly welfare center. The purpose of this research was to develop Incontinence Intervention Program for the Elderly Women (IIPE) and evaluate in its effect. Methods. The study design was quasi-experimental with pre and post-test. The study was performed for ten weeks at one elderly welfare center, Seoul, Korea. The subjects were gathered through an official announcement and informed consent was obtained. IIPE, in this study, was consisted of diagnosis, education, exercise and evaluation. The study variables were PFM exercise adherence, pelvic muscle strength, Continence self-efficacy, geriatric depression and incontinence stress. The effects of the IIPE on PFM exercise adherence, pelvic muscle strength, Continence self-efficacy, geriatric depression and incontinence stress were also evaluated. Results. The mean age of the subjects was 75.2 years. The average attendance was 6.2 times. The IIPE improved PFM exercise adherence, intra-vaginal contraction power and CSE significantly. But it was not significant in incontinence stress and geriatric depression. Other important results were that the two-finger test and urine stream interruption were more useful for elderly women with rigid vaginas in teaching and evaluating. Conclusion. The Findings suggest that IIPE is effective to the community-residing elderly. Further investigation is needed on a long-term basis with control group.

Purpose: The purpose of this study is to evaluate the interrupted chest compression time during the use of an automated external defibrillator (AED) depending on different AED practice training methods, and to report differences in self-efficacy before and after training. Methods: We enrolled university freshmen who have had cardiopulmonary resuscitation (CPR) training but have not or have had AED training but over 6 months. We examined differences between the group that practiced only shockable rhythms during training and the group that practiced both shockable and non-shockable rhythms. Results: A total of 72 individuals participated in this study, with 36 individuals each in the control and experimental groups. There was no statistically significant difference in the proficiency of AED usage between the two groups. In non-shockable cases, the experimental group showed shorter chest compression interruption time than the control group (2.30±1.21sec vs. 3.16±1.73 sec; p<0.01). In terms of self-efficacy before and after training, both groups showed higher self-efficacy after than before training. Conclusion: Individuals who underwent training that provided practice on both shockable and non-shockable rhythms had a shorter interrupted chest compression time when using the AED.

This study concentrates on the exploratory study about self-leadership securing autonomy and self-determination of the job performance for the employees of social welfare facilities like that the members set the goal of their jobs and solve the problems by themselves without exterior one-way interruption and control. For this purpose, this study set up the analysis model and hypothesis that the efficiency of the members' job performance can be promoted since the increasing self-leadership(behavior-focused strategies, natural-reward strategies, contractive thought pattern strategies) of the employees of social welfare facilities has a positive effect on empowerment and job satisfaction. Therefore, this study has significance in the aspect that it provides political suggestion for promoting the efficiency of human resource management by investigating the relationship between self-leadership and empowerment and job satisfaction through empirical analysis.

The high-voltage circuit breaker plays an important role in the electrical system because there has been a need for suitable switching devices capable of initiating and interrupting the flow of the electric fault current. It continues as the contacts recede from each other and as the newly created gap is bridged by a plasma. The arc plasma happens inside the insulation nozzle of SF6 self-blast interrupter which is newly developed as the next-generation switching principle. The ablation of PTFE nozzle is caused by this high temperature medium, the PTFE vapor from the nozzle surfaces flows toward the outlets and the pressure chamber. The vapor makes the pressure of the chamber increased by heat and mass transfer from the arcing zone. Because the rate of ablation depends on the magnitude of applied current, it decreases when the current goes to zero. The compressed gas inside the chamber flows reversely toward the arc plasma during this moment. According to this principle, the arc can be cooled down and the fault current can be interrupted successfully. In this study, we calculate arc plasmas and thermal-flow characteristics caused by fault current interruption inside a SF6 self-blast interrupter, and to investigate the effect of PTFE ablation on the whole arcing history.

Circuit breakers have traditionally employed mechanical methods to interrupt excessive currents. According to power semiconductor technology advances in power electronic device, some mechanical breakers are replaced with solid state equivalents. Advantages of the contactors using semiconductor devices include faster fault interrupting, fault current limiting, no arc to contain or extinguish and intelligent power control, and high reliability. This paper describes the design of a static $100{\pm}10%V$ and 0 to 50A DC self-protected contactor with 85A "magnetic tripping" and 100A interruption current at $2.2A/{\mu}s$ short circuit of load condition using a new power device the HARRIS MCT (600V-75A). The self-protection circuit of this system is designed by the classical ZnO varistor for energy absorption and turn-off snubber circuit ("C" or "RCD") of the MCT.
