오늘날 전력사용이 급증하면서 부하가 대용량화되는 추세에 따라 전기설비의 규모는 점차 대규모화 되고, 사회는 점점 고도정보화 사회로 발전되고 있다. 따라서, 설비의 사고 및 정전 등은 높은 전기적 의존도를 가진 고도 산업사회에 막대한 경제적 손실 및 장애를 가져다준다. 한편, 도시 환경의 미화차원에서 지중배전선로는 점차 증가하고 특히, 전력 케이블은 주로 공장 또는 대도시의 도로지반하에 분포하고 있어 사고시 복구에 많은 시간이 필요하며 교통 및 산업활동에 막대한 피해를 끼치게 된다. 이러한 반면에 우리나라에서는 배전용 케이블로 CV 케이블을 포설하기 시작한지 20여년이 경과되어 최근에 사고가 점증하고 있는 추세이다. 그리고, 근래에 포설한 케이블이라 할지라도 시공불량 및 기타 열악한 환경에 놓여 있게 되면 단시간에도 사고에 이를 수가 있어 설비 및 수용가에 원활한 전력공급 및 사고의 미연 방지를 위해 케이블의 열화상태를 정기적으로 진단할 필요가 있으며, 이를 위한 예방진단 기술의 연구가 필요로 하게 되었다. 본 논문은 이러한 배경하에서 케이블에서의 열화사고 현황, 절연 열화요인과 열화 process 그리고 절연진단기술의 현황 등을 알아보고, 국내 배전선로 계통인 3.3kV 및 6.6kV급 CV 케이블의 열화 진단기술 현황 및 향후 전망에 대하여 기술하였다.

The present study set out to explore the acculturative stress and mental health(depression) of Korean women living in Britain according to socio-demographic factors, social relations and social supports level. 152 Korean women's data were collected and analyzed with frequency, correlation, ANOVA. Analysis revealed that women's acculturative stress and depression level was 2.50(moderate) and 1.66(slightly low) respectively. Acculturative stress level showed correlation with depression level. Among demographic variables, acculturative stress was significantly different from residence period in Britain, marriage and economic state and the level of depression was also different from job and economic state. The group which has frequent relationships with British and high level of social supports showed low acculturative stress. The group has high level of social supports also showed low depression. These findings highlight the importance of concerns and interventions about acculturation and mental health of Korean immigrant women and community services for the new immigrant women to improve their acculturation and mental health.

This paper examines the labor entry of conditional welfare recipients. This paper focuses on two questions. First, what is the percentage of conditional welfare recipients who have labor entry? Second, what are the predictors in the labor entry and the duration to the entry? Using Data about 917 welfare recipients who participated in the self-sufficiency programs of the Offices for Secure Employment in Seoul, this paper attempts to answer the above questions. Logistic regression analysis and survival analysis are adopted to identify variables predicting labor entry of conditional welfare recipients. This paper also utilizes a multiple imputation method to deal with the limitation of data by the missing values in some variables. The major findings are as follows: about 43.8% of the conditional welfare recipients have successful labor entry; and in the labor entry and the duration to the entry, gender, household, information and referral services for employment, health and willingness for self-sufficiency are the predictors that are statistically significant. Among these variables, health and willingness for self-sufficiency are more noticeable; it is recognized that programs to care for health of welfare recipients who want to have the labor entry and counseling programs to strengthen welfare recipients' willingness for labor entry are very important for them to be successful in the labor entry. This paper provides a basic knowledge about realities of the conditional welfare recipients' labor entry, identifies research areas for further research, and develops policy implications for their self-sufficiency.

This study aims to evaluate the influence of oral contraceptive(OC) on periodontal disease. Research data was used the results derived from the Fourth Korean National Health and Nutrition Examination Survey(KNHANES), and 1,101 Korean women, aged 19 to 50 years with non-pregnant and premenopausal, were selected. The chi-square test and logistic regression analysis were performed to identify the relationship between OC use and periodontal disease, according to factors of demographic and socioeconomic, oral health behavior, OC use period, and periodontal status. In the results, OC use was statistically related with age, marital status and smoking. No significant differences were found in between the gingival condition and current OC use. The prevalence of periodontal disease increased with age, but did not have significant correlations with period of OC usage, smoking and oral health behavior. Final analysis was indicated that OC use is not associated with periodontal disease, regardless of adjustment for confounding variables.

This study purports to empirically examine the potential effect of the level of social trust on their welfare consciousness level. Although previous studies in the field have focused on socio-economic or class-oriented variables, the accumulated results have shown that the effects were inconsistent at best in Korean context. In order to overcome the limits of theoretical assumptions from mainstream Marxists and institutionalists, this study suggests the relative autonomy of social consciousness and its independent effect on welfare consciousness. The analysis shows that both foundational variables, income levels and labor market participation, and the level of social trust have significant impacts upon the respondents' level of welfare consciousness.

The purpose of this study was to investigate the association between socioeconomic status and blood heavy metal concentration in Korean adult population using the Korea National Health and Nutritional Examination Survey(KNHANES 2013-2015). Multiple logistic regression analysis was used to determine the association between socioeconomic status and the blood heavy metal concentration. Positive association was found between education and income level and blood concentration of mercury while those of lead and cadmium were negatively associated education and income level in Korean adult population (P for trend <0.001). At the point of an increase in the prevalence of heavy metal concentrations in the blood, a national public health policy will be needed to address the inequity of health due to socioeconomic factors.

Since the 1970s, along with an increasing number of motor vehicles in Korea, road crashes and casualties started to increase and eventually resulted in a serious public health problem starting from the beginning of the 1990s. Government authorities, however, have been not so proactive with reducing road crashes and injuries as well as deaths and have been reluctant to design effective safety strategies that could be established in collaboration with relevant multidisciplinary professionals. This paper aims at showing the status of road safety versus socioeconomic development in Korea and highlighting safety strategies that particularly need the participation of medical professionals. Six indicators to measure socioeconomic development and two indices for road safety were examined and international comparisons were made, finding road safety in Korea has been not corresponding to its level of development. The imbalance between socioeconomic development and road safety will certainly require the government authorities to look for effective safety strategies necessitating cooperation and collaboration with relevant experts including medical professionals. To make a provision for such needs in the near future, studies and experiences previously reported in the literature of traffic medicine and the world congresses of the International Traffic Medicine Association since 1984 were reviewed and categorized to focus on the strategies as well as measures that would be most effective in a mid-income country such as Korea.

The purpose of this study was to analyze visitors' behavior in Hallyo-Haesang National Park, Korea. To accomplish the purpose, questionnaire survey, using self-developed questions, was employed from August 21 to 23 in 1998. 303 samples for the survey were selected in 4 different zones(Koje, Tongyong, Namhae, and Odongdo) within park boundary. As the results, socioeconomic characteristics, such as gender, education and income level, age, and others, were showed similar trends with results from visitor surveys in other national parks. Most respondents were pointed out unintentional violation due to habit as a major reason of littering. And, majority of respondents didn't know the Clean-up-Time Movement Program in this park. In addition, ecosystem condition, natural landscape, trash problem, safety, and kindness of park rangers were recognized as the major influencing factors that can affect to visitors' recreation experience in this park but existing conditions for each influencing factor were evaluated lower than level of their expectation. Overall level of recreation satisfaction in Hanryohaesang national park were, however, perceived in the affirmative.

The purpose of this study was to investigate factors affecting perceived oral health status according to socioeconomic status and community periodontal index(CPI) and decayed, missing, and filled teeth(DMFT) using the 6th Korean national health and nutritional examination survey(KNHANES VI) and provide a basic data for plan of policy. The higher the age, the lower the household income and education level, the worse the subjective oral health had better oral health and there was a tendency that the respondents who had no oral exam within 1 year and experienced CPI or DMFT estimated their own health as worse. It is needed to make policy development to resolve the inequality of oral health.

Ageism, attitudes toward aging, and body satisfaction play significant roles in determining older women's perceptions of successful aging. In addition, subjective socioeconomic and health status can act as major identifiers in determining the overall level of physical and social well-being in old age. Research for this exploratory study includes: 1) exploring the overall levels of ageism perception, attitudes toward aging, and body satisfaction among older women and 2) identifying the differences in ageism, attitudes toward aging, and body satisfaction between high and low subjective socioeconomic and health status of older women. Data for this study were collected through an online questionnaire of 221 older women. The results revealed that older women's perceptions of ageism, aging attitudes, and body satisfaction were significantly different based on subjective socioeconomic and health status. In general, older women with higher levels of subjective socioeconomic and health status reported more positive perceptions and attitudes toward aging along with higher levels of body satisfaction. The results implied that subjective health status was a more powerful indicator differentiating the aging-related perceptions of older women than the subjective socioeconomic status. This study supports the need for a conscious effort to reduce ageism that ultimately improves the overall well-being of all members in society.
