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.

취업 중 자영업이 차지하는 비중이 상당함에도 불구하고, 자영업 선택의 결정요인에 대한 연구는 일천하다. 특히 여성에게 있어 결혼과 자녀 보육이 취업에 장애요인으로 작용하는 현실을 고려할 때 상대적으로 근로시간의 선택이 자유로운 자영업은 여성의 가사노동과 경력 유지를 병행하는 하나의 대안이라 할 수 있다. 본 연구는 여성의 취업 미취업의 선택과 피고용 자영업의 선택을 동시에 고려하는 이변량 프로빗 모형(bivariate probit model)을 "한국노동패널" 1차년도(1998) 자료에 적용하는 한편 취업한 여성을 3차년도(2000)까지 추적하여 이 기간 중 발생한 노동공급의 변화-노동시장에서 퇴장, 근로시간 증가, 근로시간 감축-의 결정요인을 다항로짓 모형(multi-nomial logit model)을 이용하여 분석한다. 취업의 선택에서 어린 자녀의 존재는 유의한 부(-)의 효과를 갖은 반면 자녀 보육 보조자의 존재는 유의한정(+)의 효과를 갖는 것으로 나타나며, 자영업의 선택에서 자녀의 존재는 정(+)의 효과를 가지나 통계적으로 유의하지는 않게 나타난다. 결혼과 어린 자녀의 수의 증가는 노동시장에서의 퇴장에 유의한 부정적 효과를 미친 반면 근로시간의 감축에는 유의한 효과를 미치지 않는 것으로 나타난다. 임금근로자와 비교할 때, 피용자가 없는 자영자와 무급가족종사자는 근로시간 증가보다는 노동시장 퇴장에서 퇴장하는 확률이 낮고 피용자가 없는 자영자는 근로시간을 감축하는 확률이 낮은 것으로 나타난다. 근로시간의 유연성으로 가사노동과 시장노동의 병립이 용이한 자영업을 잠재 여성인력의 활용과 경력단절을 막는 방안으로 고려하는 정책적 함의를 갖는다.

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.

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.
