In this paper an expert system is developed to decide the resetting area of protective devices in power transmission systems. A configuration change in power transmission networks from a substation extension such as new line or bus addition need resetting of protective devices around the point of configuration changes. To find the resetting area in complex power system is very difficult, especially when the distance protective relays are considered to be reset. The proposed expert system, in this paper to find the resetting area has many rules based on the changes of fault currents and apparent factors from the power system alteration. It solves the problem to find relay resetting area using the network information in the database and the rule-base. The case study shows a result of the problem to find relay resetting area in KEPCO system when there is any configuration change.

조손가족 청소년들은 일반 가족의 청소년들에 비해 부정적인 환경에 노출됨으로써 심리사회적으로 부정적인 영향을 받는 경향이 높기 때문에 중요하게 검토되어야 한다. 이와 관련하여 조손가족 청소년의 위험요인, 보호요인과 학교 적응유연성 간의 관계를 다룬 연구가 이루어지고 있으나, 대부분 청소년의 위험요인, 보호요인과 학교 적응유연성 간의 단편적인 관계를 설명하는데 그치고 있다. 이에 본 연구는 조손가족 청소년의 위험요인과 보호요인 간, 그리고 이들과 학교 적응유연성 간의 매개적인 경로와 인과관계를 살펴보는데 목적을 두었다. 이를 위해 전국 단위의 조손가족 청소년 328명을 대상으로 조사하였고, 분석방법은 SEM을 사용하였다. 분석결과는 다음과 같다. 조손가족 청소년의 위험요인, 보호요인과 학교적응유연성 간의 직접효과와 보호요인의 매개효과를 검증하기 위해 구조회귀모형을 검증한 결과 모형의 적합도가 타당하게 나타났다. 위험요인은 청소년의 학교적응유연성에 부정적 영향을 미치며(교사의 무관심, 부정적 애착관계, 우울불안 순), 보호요인은 학교 적응유연성에 긍정적 영향을 미쳤다(교사의 지지, 자아존중감 순). 또 보호요인은 위험요인이 학교 적응유연성에 미치는 부정적 영향을 매개하여 완화시키는 것으로 나타났다.

Objective : Hospital workers' mental health has deteriorated because of the ongoing COVID-19 pandemic. The purpose of this study was to investigate the impact of the prolonged COVID-19 pandemic on the mental health of hospital workers and its determinants. Methods : Two surveys were conducted among employees working in a hospital that received COVID-19 patients from the early phase of the pandemic in South Korea. Data on demographics, perceived threat, workplace evaluation, resilience, and mental health status were collected using the Korean General Health Questionnaire-20 in the initial phase (February 2020) and during the third wave of COVID-19 (December 2020) for 467 and 545 workers, respectively. The mental health of hospital workers in the two phases was compared, and the risk and protective factors during the third wave were investigated. Results : The proportion of patients in the psychiatric high-risk group increased from 2.8% in the initial phase to 11.4% during the third wave. The perceived threat, workplace evaluation, and resilience of respondents deteriorated. Risk factors for mental health during the third wave included the perceived threat items of job stress, loss of control, and considering resignation. Protective factors included presence of children, workplace satisfaction, and hardiness in resilience. Conclusion : Hospital workers' mental health deteriorated as the pandemic progressed. General stress and tension such as job stress, loss of control, considering resignation rather than COVID-19-specific stress had negative effects on mental health of hospital workers. Therefore, care for work stress itself can be helpful to maintain the mental health of hospital workers. Also, governance to improve workplace satisfaction or hardiness in resilience can be a potential protective factor for hospital workers' mental health during the prolonged pandemic.

Purpose: This study aimed to identify the factors affecting compliance with personal protective equipment (PPE) use among medical device reprocessing staff. Methods: This descriptive cross-sectional study included 163 cleaning staff members from ten general hospitals in Seoul and Gyeonggi. Data were collected using self-report questionnaires administered between July and September 2023. Analysis included t-tests, ANOVA, Pearson's correlation coefficient, Bonferroni correction, and multiple regression, conducted using SAS ver.9.4. Results: Statistically significant differences in compliance with PPE were found based on department and exposure to contamination within six months (t=-2.82, p=.007). Attitudes toward PPE (r=.22, p=.006) and awareness of the safety climate (r=.22, p=.006) showed a statistically significant positive correlation with PPE compliance. Factors influencing use of personal protective equipment by cleaning staff during medical device reprocessing were department, compliance with PPE, and awareness of the safety climate. The explanatory power of these factors was 58.0%. Conclusion: Improving PPE compliance and creating a safe cleaning environment entails fostering a supportive safety climate. Additionally, regular training that takes into consideration the characteristics of the cleaning staff, alongside continuous monitoring, is required.

Objectives: The purpose of this study was to conduct a meta analysis of the previous studies on parental factors related to psychological and social maladjustment of school children and to examine the moderate effects of publication year using the meta-regression analysis. Method: Subjects of studies was academic journals and thesis published on 1996-Feb. 2016. Final result of selection was 353(122 journal articles, 231 master's thesis & dissertations) and total number of sampling was 126,776 school children. Results: Parental factors had medium effect sizes on psychological and social maladjustment of school children. Parental risk factors had bigger effect size than protective factors on children's maladjustment. There were a tendency that effect size of some parental factors were increased as publish year went by. Conclusions: Attachment, positive communication, and positive marital relationship were major protective factors which had reduced maladjustment of children. Psychological control and negative marital relationship were the strongest risk factors. The impact on parental factors on maladjustment of children were getting stronger recently.

The purpose of this study is to investigate attitude factor related to hearing conservation and to find attitude affecting the preventive behavior for hearing conservation. The research method used in this study was self-administered questionnaire. Samples of the study were composed of 353 workers exposed noise selected randomly in 10 ship-building manufacturing companies. Authors extracted following 9 factors related hearing conservation from 26 attitude propositions prepared from previous study results and health belief model; (1) general perceived susceptibility, (2) relative perceived susceptibility compared with colleagues, (3) concern to the personal protective devices, (4) perceived severity and concern to the hearing capacity, (5) concern to the hearing and noise assessment, (6) concern to the control noise and hearing conservation, (7) group pressure and reason of wearing protective devices, (8) apathy of hearing loss from noise, (9) knowledge about hearing conservation. Attitude factors affecting the preventive health behavior were general perceived susceptibility, concern to the noise control and hearing conservation, and concern to the personal protective devices in the case of wearing personal protective devices. But in the case of avoiding noise exposure as preventive health behavior, perceived severity and concern to the hearing capacity was a significant attitude factor with knowledge about hearing conservation.

Objectives: With increasing concerns for the rapidly growing minority population in South Korea, this literature review addressed a range of mental health risks among multiethnic youths (MY) in South Korea by 1) comparing mental health outcomes with those of native-born youths and 2) identifying multiple layers of relevant environmental factors, from family and school relationships to culture. Methods: We reviewed 54 studies that fulfilled specific inclusion criteria. Results: Multiple common risk/protective factors, including family separation, family relationship quality, parental socioeconomic and mental health status, social relationships at school, and cultural acceptance, were noted. Conclusion: In general, empirical evidence indicates that minority youths have relatively heightened risks for emotional and behavioral problems. Future studies must elucidate the complex interplay between multiple risk and protective factors and the long-term adaptation and mental health service utilization of MY.

Purpose: The aim of the study was to identify risk and protective factors/markers for cervical cancer and cervical intraepithelial neoplasia 3 (CIN3) in Israeli Jewish women in order to settle the discrepancy of low incidence rate of cervical cancer and relatively high incidence rate of CIN3. Materials and Methods: We conducted two case control studies, which examined the association between potential risk and protective factors/markers for cervical cancer or CIN3 using self administered detailed questionnaires. Results: For studying cervical cancer, 40 cases and 40 matched controls were interviewed. In the univariable and multivariable analyses older age, depression or anxiety and ever smoking seemed to act as independent risk factors/markers, while older age at first intercourse was protective. For studying CIN3, 99 cases and 79 controls were interviewed. Multivariable analysis has demonstrated that being born in Israel, depression or anxiety and ever smoking were independent risk factors/markers for CIN3. Conclusions: The risk factors/markers studied, that were associated with cervical cancer or CIN3 among Jewish women in Israel, are similar to those reported in other parts of the world, and do not explain the observed discrepancy of high in-situ cervical cancer rates and low invasive cervical cancer incidence in Israel.
