  • As Indonesia is rich in natural resources, nuclear power remains a low priority among energy alternatives. However, Indonesia needs to introduce nuclear power to improve the atmospheric environment and to support sustainable economic growth. This study conducted a two-stage survey of logit-probit and analytic hierarchy process to analyze the perception of Indonesian energy policymakers regarding the introduction of nuclear power, the potential for change, and key decision factors. The analysis confirms that the perception of nuclear power is positive and that the willingness to expand nuclear power can improve if negative conditions, such as underdeveloped technology level, foreign aid and assistance, and safety issues are addressed. In addition, it is confirmed that the policy makers consider political/social and environmental factors to be more important for decision-making. The results of this study can give inplications and be used as a key reference for Indonesia's nuclear power policy

  • The contribution of degraded human performance (e.g., human errors) is significant for the safety of diverse social-technical systems. Therefore, it is crucial to understand when and why the performance of human operators could be degraded. In this study, the occurrence probability of human errors was empirically estimated based on the complexity of proceduralized tasks. To this end, Logistic regression analysis was conducted to correlate TACOM (Task Complexity) scores with human errors collected from the full-scope training simulator of nuclear power plants equipped with analog devices (analog environment). As a result, it was observed that the occurrence probability of both errors of commission and errors of omission can be soundly estimated by TACOM scores. Since the effect of diverse performance influencing factors on the occurrence probabilities of human errors could be soundly distinguished by TACOM scores, it is also expected that TACOM scores can be used as a tool to explain when and why the performance of human operators starts to be degraded.

  • 본 연구는 저소득 모자가구주의 대부분이 일을 하고 있음에도 불구하고 경제적으로 여전히 어려운 노동빈민(working poor)으로서의 위치에서 벗어나지 못하고 있다는 문제의식 속에서 비롯되었으며, 저소득모자가구의 생활실태를 최근 사회과학 내에서 논의되고 있는 사회적 배제 개념을 이용하여 분석하고 이의 극복방안으로서 사회적 통합과 연대모색을 제안하였다. 구체적으로 본 연구는 남성가장을 중심으로 한 일반가구, 일반 모자가구, 사회적 빈곤선 이하에 놓인 저소득모자가구를 대상으로 각 가구유형별 특성과 생활실태를 비교분석하고 이를 통해 전반적인 모자가구의 사회적 배제과정을 살펴보았다. 본 연구는 2000년 지역사회복지협의회의 "사회복지욕구조사" 원자료를 이차분석(secondary analysis) 하였으며 총 3,182가구가 최종적으로 분석에 포함되었다. 연구결과에 의하면 전반적으로 모자가구는 일반모자가구, 저소득모자가구에 상관없이 고용형태, 주거형태, 소득, 소비생활 측면에서 일반(남성가장)가구에 비해 어려움을 겪고 있었다. 일반가구에 비해 모자가구는 가족으로부터 자원을 제공받기보다는 오히려 장애, 만성질환 등의 가족원을 보호해야 하는 상당한 부담을 안고 있었으며, 사회적 안전망에서도 모자가구는 전반적으로 제외되어 있는 것으로 나타났다. 이것은 모자가구가 일반가구에 비하여 전반적으로 사회적으로 취약해지거나 고립될 가능성이 매우 높은 현실을 반영하며, 현재 공식적으로 빈곤층, 혹은 저소득층으로 분류되지는 않았지만 일반모자가구도 포괄적인 사회적 안전 망이 확립되지 않는다면 향후 저소득층으로 배제될 가능성이 매우 높다는 사실을 확인시켰다. 마지막으로 연구결과에 기초하여, 전체 모자가족의 사회적 배제를 극복할 수 있는 사회적 통합방안이 모색되었다.

  • Objectives: Physical activity is well known as one of the most effective health behaviors for maintaining and promoting health. The purpose of this study was to investigate the regional variation, compositional and contextual factors on physical activities in Korea. Methods: This study analyzed data of 6,353 adults in 4th-1, 2 Korea National Health and Nutrition Examination Survey (KNHANES). Independent variables were compositional factors that included general characteristics, health behaviors, health status, and contextual factors that included physical environment, political environment, and social safety net. Dependent variables were vigorous physical activity, moderate physical activity, and walking activity. Multilevel analysis were used to determine a variation of physical activity between levels of compositional factors and contextual factors. Results: Physical activities of the Korean people were affected by the regional variables. Financial independence and population density were related with moderate physical activity significantly. Population density, school sport or rally spaces, cultural facilities, and social safety concerns were related with walking activity significantly. These variables impacted on physical activities along with variables at the individual level. Variance Partition Coefficient were 9.94% at moderate physical activity and 2.91% at walking activities, respectively. Conclusions: The results suggest that the regional variables should be considered when planning public intervention to promoting physical activities in Korean adults.

  • 본 연구는 노동자가 업무 이외의 이유로 아프게 되면, 노동시장에서 어떻게 고용 불안정성을 경험하고 또 빈곤화를 경험하는지 분석한다. 특히 아픈 노동자에 대한 한국 사회보장제의 소득보장 기능을 분석하고, 상병수당이 부재한 한국 복지국가의 특수성이 아픈 노동자의 빈곤화에 미치는 영향에 주의를 기울이며 사례 연구를 실시했다. 연구 결과, 아픈 노동자들은 상병으로 고통을 경험해도 일단 '아파도 참는다'. 특히 불안정 노동을 하는 비정규직 노동자들은 아프면 몸을 회복할 수 있는 휴직을 누릴 수 있는 여지가 없이 실직을 경험하게 된다. 그리고 아파서 실직을 경험하게 되어도 소득 감소분을 채우기 위해 더 불안정한 노동이라도 지속하는 경향이 있었다. 그 과정에서 가족 등 주변 사회적 자원이 무너지는 양상도 보이면서, 빈곤화의 경로를 밟는 것이 관찰됐다. 상병과 실업이라는 복합적인 위기에 처한 노동자를 위한 사회보장제도에도 사각지대가 확인됐다. 산재를 겪은 노동자들은 산업재해 신고를 기피하는 사업주 탓에 제도의 혜택에서 벗어나기도 하였고 또 상병으로 실직한 노동자를 고용주가 '자발적 실업'으로 신고하여 실업수당에도 배제됐다. 본 연구는 노동자의 상병으로 인한 일자리 불안정화와 빈곤화 과정을 구체적으로 확인하는 연구로 의의가 있다. 또한 상병수당의 부재와 아픈 노동자의 관계가, 상병수당을 포함하여 한국 소득보장제에 어떠한 학술적, 정책적 함의를 가지는지 고찰했다.

  • Objectives: An objective of this study was to perform a risk assessment and social cost-benefit analysis for revising permissible exposure limits for seven substances: Nickel(Insoluble inorganic compounds), benzene, carbon disulfide, formaldehyde, cadmium(as compounds), trichloroethylene, touluene-2,4-diisocyanate. Materials and Methods: The research methods were divided into risk and hazard assessment and cost-benefit analysis. The risk and hazard assessment for the seven substances consists of four steps: An overview of GHS MSDS(1st), review of document of ACGIH's TLVs (2nd), comparison between international occupational exposure limits and domestic permissible exposure limits(3rd), and analysis of excess workplace and excess rate for occupational exposure limits based on previous work environment measurement data(4th). Total cost was estimated using cost of local exhaust ventilation, number of excess workplace and penalties for exceeding a permissible exposure limit. On the other hand, total benefit was calculated using the reduction rate of occupational disease, number of workplaces treating each substance and industrial accident compensation. Finally, the net benefit was calculated by subtracting total cost from total benefit. Results: All the substances investigated in this study were classified by CMR(Carcinogens, Mutagens or Reproductive toxicants) and their international occupational exposure limits were stricter than the domestic permissible exposure limits. As a result of excess rate analysis, trichloroethylene was the highest at 11%, whereas nickel was the lowest at 0.5%. The excess rates of all substances except for trichloroethylene were observed at less than 10%. Among the seven substances, the total cost was highest for trichloroethylene and lowest for carbon disulfide. The benefits for the seven substances were higher than costs estimated based on strengthening current permissible exposure limits. Thus, revising the permissible exposure limits of the seven substances was determined to be acceptable from a social perspective. Conclusions: The final revised permissible exposure limits suggested for the seven substances are as follows: $0.2mg/m^3$ for nickel, 0.5 ppm(TWA) and 2.5 ppm(STEL) for benzene, 1 ppm(TWA) for carbon disulfide, $0.01mg/m^3$(TWA) for cadmium, 10 ppm(TWA) and 25 ppm(STEL) for trichloroethylene, 0.3 ppm(TWA) for formaldehyde, and 0.005 ppm(TWA) and 0.02 ppm(STEL) for toluene diisocynate(isomers).

  • Medical litigation, as a method of resolving medical disputes, has been a huge burden on both the patient and medical institution as it is both costly and time-consuming. The Korea Medical Dispute Mediation and Arbitration Agency has created a dispute mediation process as a method of alternative dispute resolution(ADR). Being in its early stage of implementation, there are still areas requiring improvement as some functions overlap with the Korea Consumer Agency's damage redress and mediation process. This study examines the problems of existing practices in medical litigation while reviewing the mediation process of the two agencies from legal/administrative aspects, and provides an in-depth analysis of the situation through case studies and interviews. While the Korea Medical Dispute Mediation and Arbitration Agency offers many advantages in resolving medical disputes, there must be a distinct division of roles and mutual cooperation with the Korea Consumer Agency. Considering the increasing amount of compensation in medical disputes, medical professionals are being requested to carry medical malpractice insurance. However, this has yet to become a general trend in the medical field despite the growing social demand. As such, the coverage of medical malpractice insurance should be expanded to prevent medical accidents from escalating into medical disputes, thus acting as a social safety net. This study seeks to examine the methods of medical dispute resolution and to allow institutional provisions to reduce the social costs arising from such disputes.

  • Corresponding to the rapid growth of the aging population without an adequate social safety net for the elderly, older people face great disadvantages due to sudden illness or poor health and a lack of support from the younger generation. Furthermore, older women are suffering from a drastic deterioration of their economic status because of insufficient retirement savings. Examining the impact of labor force participation and living arrangement on health status and life satisfaction in later life, it is important to consider gender differences in context of social policies for the elderly. Using data based on a stratified national sample of the elderly by the Korean Longitudinal Study of Aging (KLoSA), multiple regression model were used to estimate the relationships between labor force participation and health status and subjective life satisfaction concerning the quality of their later life. The result indicates that good health status and high level of life satisfaction are associated with the type of paid work status for the elderly men, but those are associated with the type of non paid work, such as family businesses employees for the elderly women. Significant differences in chronic health condition and subjective life satisfaction by employment characteristics are found among the elderly. In addition, older women's high level of life satisfaction was associated with the participation of the social activity. The major conclusion from these results should help us understand gender differences in the elderly and acknowledge further exploration of gender variations in these people's later life.
