In the current study, automatic tool compensation is accomplished by using a finite element stamping analysis for a center roof rail made of UHSS in order to satisfy the specifications for shape accuracy. The initial blank shape is calculated from a finite element inverse analysis and potential forming defects such as tearing and wrinkling are determined by the finite element stamping analysis based on the initial tool shape. The blank shape is optimized to meet the shape requirements of the final product with the stamping analysis, and die compensation is determined with the information about springback. The specifications for shape accuracy were successfully achieved by the proposed die compensation scheme using the finite element stamping analysis. The current study demonstrates that the compensation tendency is similar when the proposed scheme is used or when the compensation is performed by trial and error in the press-shop. This similarity verifies that the automatic compensation scheme can be used effectively in the first stage of tool design especially for components made from UHSS.

The work-related diseases due to continuous overwork are mainly cerebro- and cardio-vascular ones, which is commonly called 'Karoshi', death from overwork. Many factors are capable for Karoshi : occupational stress in relation to technological renovation and industrial rationalization, competitive social structure, and accumulated fatigue accured to long time or irregular working. And its occurence is on the rise. The World Labor Report 1993 released by ILO, pointed out the diseases related to overwork and stress as one of the most important occupational health problem. In Korea, social awareness of Karoshi is at an infant stage, and reliable statistics for its occurence are not compiled in a convenient manner. Despite the rising Karoshi, there are no reliable clauses in workmen's compensation enough to settle down the disputes. Therefore, it is not uncommon that the Labour Ministry and Civil Court find difficulties in reaching an agreement. This study was intended to provide proper compensation and prevention program for workers by suggesting reasonable compensation clauses for the death from overwork. This study consists of two comparative reviews on the compensaton clauses for the death from overwork. One is to review legal standards of Karoshi among three countries, such as Korea, Japan and Taiwan. The other is to investigate the cases of Karoshi in Korea, 121 cases identified at the Labor Welfare Corperation and the Labour Ministrial process of examination and reexamination, and 73 leading cases at the High Court of Justice. The main findings of the study are as follows : 1. Comparisons of comperative review on compensation clauses for the death from overwork among three countries. 1) All of three countries have the same kinds of disease for compensation, which were cerebro-and cardiao-vascular diseases, while for cardiac disease group, Korea has the smaller number of diseases for compensation than Japan. 2) As for the definition of overwork, the three countries share equally that overload for one week prior to collapse is considered as an important factor, but accumulated chronic fatigue is disregarded. 3) As the basis of overwork, in Japan, there is a tendency to move from the conditions of an ordinary healthy adult to those of the individual concerned in Japan, whereas there is no such concern yet in Korea. 4) All the three countries use a common standard of medical judgement in demonstrating causal relationship between a job and a disease. However, Korea is progressive in the sense that in the case of CVA at worksite, the worker himself has no obligation to prove the cause. 2. The results of a comparative review on excutive decisions by Labor Ministry and judicial decisions by the Court in Korea : A judicial decision is based on the legalistic probability, but a excutive decision is not. Therefore, excutive decisions have such restrictions that : 1) TIA (transitory ischemic cerebral attack) and myocarditis are excluded from compensation, and there is little consistency of decision in the case of cause-unknown death. 2) There is a tendency not to compensate for the death from overwork since the work terms such as repeated long-time working, shift work or night-shift work are not considered as overloading. 3) There is a tendency to regard the conditions of a ordinary healthy adult rather than those of the individual concerned(age, existing diseases, health state, etc.) as the comparative basis of overload. 4) There remains a tendency not to compensate for the death from overwork in the case of collapse occuring out of workplace, on the ground of 'on the course of working' and 'in the cause of accident'. Through the study, the fact manifests itself that Korea's compensation clauses for work-related diseases due to overwork are very restrictive. So, it is necessary to extend the Labor Ministry's clauses of compensation for the death from overwork following to the recent changes of other countries and internal judicial decisions. This is very important in the perspective of occupational health that aims at health promotion of workers including prevention of the Karoshi.

인식 가능한 피해자 효과(Identifiable victim effect)는 추상적인 피해자보다 인식 가능한 피해자에게 더 큰 동정심과 도움행위가 나타나는 현상을 말한다. 본 연구에서는 이 현상을 일반인들의 직관적인 법적 판단 상황에 적용해 피해자에 대한 인식이 제3자의 처벌 및 보상 판단에 미치는 영향을 검증하고자 했다. 그리고 이런 법적 판단에 대한 인식 가능한 피해자 효과를 통해 피해자의 실명과 신상을 전면에 내세워 여론의 관심과 지지를 얻어 관련 범죄의 처벌 강화를 목표로 하는 피해자형 설명법안의 효과를 설명하고자 하였다. 이를 위해 법적 판단에 필요한 법률적 요인을 배제한 교통사고 시나리오를 작성해 교통사고 피해자의 정보를 조작해 실험을 진행하였다. 실험1에서 참가자는 각 집단 별로 사고 피해자를 익명으로 제시한 조건(비인식 조건)과 이름, 나이 등의 신상정보를 함께 제시한 조건(인식 조건)을 읽고 배심원으로서 양형과 합의금을 판단하였다. 그 결과 피해자 신상정보의 유무는 제3자의 양형 및 합의금 판단에 영향을 미치지 않았지만, 세상의 공정성에 대한 믿음에 의한 조절효과가 나타났다. 즉, 피해자를 구체적으로 인식했을 때 세상이 공정하다고 믿을수록 더 높은 처벌과 보상을 원하는 것으로 나타났다. 실험2에서는 익명의 피해자(비인식 조건)와 성행 정보가 긍정적(긍정인식 조건)이거나 부정적인 피해자(부정인식 조건)를 비교해 피해자 특성이 가해자 처벌과 피해자 보상에 미치는 영향을 관찰하였다. 그 결과 피해자를 부정적인 사람이라고 인식했을 때 피해자가 누군지 알 수 없을 때보다 더 적은 보상 판단을 하는 것으로 나타났다. 또 부정적인 피해자 조건을 제외한 모든 조건에서 이전 판례의 평균보다 더 높은 가해자 처벌, 피해자 보상 판단을 하는 것으로 나타났다. 본 연구는 법률적 요인 외의 피해자 특성이 제3자의 법적 판단에 영향을 미친다는 것을 확인하였다. 나아가 법적 요인과는 무관하게 높은 처벌과 보상 판단을 피해자형 실명법안의 효과와 함께 해석하며 공정한 양형 기준 설정을 위한 사회적, 법적 논의와 후속 연구를 제안하였다.

Purpose: This study was done to learn the status of occupational injuries and illnesses among Korean nurses. Methods: Thirty four articles published between 1990 and 2007 were selected using keywords as nurse and back pain, musculoskeletal symptom, violence, needle stick injuries and latex allergy from the database. The 609 RN cases among the workers' compensation data from 2005 to 2007 were analyzed by descriptive statistics. Results: Based on the analysis of the articles, the most frequent work-related illness and injuries were the musculoskeletal symptoms including back pain. The prevalence of back pain was ranged from 36.5% to 98.5%. Tuberculosis cases were the most frequent and the musculoskeletal cases were the second rank in the workers' compensation data. In the case of violence, there has been an increasing tendency since 2000 in the articles and workers' compensation data. The relatively high percentage of compensation cases occurred among the ones working in small institutions and with less than one year experience. Conclusion: The further research on the nurses' work-related illness and injuries needs to consider the measurement tool selection and longitudinal design. The various types of contribution to the occupational health in nursing is suggested to improve the nurses' health and safety.

This study examines a P+multi resonant-based voltage control for voltage harmonics compensation under the islanded mode of a microgrid. In islanded mode, the inverter is defined as a voltage source to supply the full local load demand without the connection to the grid. On the other hand, the output voltage waveform is distorted by the negative and zero sequence components and current harmonics due to the unbalanced and nonlinear loads. In this paper, the P+multi resonant controller is used to compensate for the voltage harmonics. The gain tuning method is assessed by the tendency analysis of the controller as the variation of gain. In addition, this study analyzes the slight voltage magnitude drop due to the practical form of the P+multi resonant and proposes a counter method to solve this problem by adding the PI-based voltage restoration method. The proposed P+multi resonant controller to compensate for the voltage harmonics is verified through the PSIM simulation and experimental results.

The purpose of this paper is to explain the entropic measures could cause the organization to increase the entropy. The organization as an open system has a tendency to input new energy to adapt itself to the change in its surroundings. This intention of inputting energy into organization is based on the second law of thermodynamics, the laws of entropy.Entropy is a measure of disorder, or a measure of progressing towards thermodynamic equilibrium. The entropy of an isolated system increases. Organizations have to open to their environment, have to do something to reduce their entropy. But, this attempt to reduce entropy entails another entropy. This study shows the side effects by giving examples of illegal receipt of worker's compensation insurance. The implications through the cases of illegal receipt of workers' compensation are as follows. Firstly, organizational policy is that inaction in itself may be the best policy, unless we always think the action best. Secondly, public organization should be careful in substituting business management in the private sector such as customer satisfaction(CS) for the value in public sector. Thirdly, the setting the expiration date of organizational policy could be the way to slow down the degree of entropy.

콘크리트의 자기수축을 예측하기 위해 기존 수화도와 자기수축의 진행 속도 차이를 불포화공극 생성 속도로 가정하고 시멘트 페이스트의 자기수축 실험을 통하여 물-결합재비에 반비례하는 불포화공극 보정계수를 산정할 수 있었다. 이를 자기수축 기여 성분과 미기여 성분이 고려된 변형 Pickket 모델을 이용하여 콘크리트의 자기수축을 예측하였으며, 실험값 및 기존 Tazawa 모델과 일치하는 경향을 나타내어 불포화공극 보정계수에 의한 자기수축 예측이 타당함을 알 수 있었다. 그러나 강도의 함수로 설정된 기존 CEB-FIP 자기수축 예측 모델의 경우 최종 자기수축률과 자기수축 발현 시간함수에 대하여 다소의 수정이 필요할 것으로 판단된다.

This study analyzed the personal characteristics of the SW industry workers and investigated how these individual characteristics affect the satisfaction of job satisfaction. In addition, we examined how satisfaction with these jobs varies according to satisfaction with internal control and external compensation. This study surveyed the employees of SW industry in Seoul and Daegu from September 15 to October 15, 2017. The results of this study are as follows. First, personal characteristics have a significant effect on job satisfaction. Second, extroversion, openness, friendliness and integrity have a significant effect on job satisfaction. This is consistent with the previous study (Park and Song, 2005), which suggests that people with extroversion are more likely to feel positive emotions such as joy. In addition, it is believed that open empathy has a tendency to share with others in work, and positive emotions in work have a significant influence because they show high achievement in work. A friendly person places great importance on a comfortable and harmonious relationship with others, so he builds and maintains good relationships with the members of the organization by trusting others in the organization. Third, nervousness showed no significant effect on job satisfaction. This is consistent with the previous study (Yoo, 1987) in which the more nervousness is, the more unpleasant emotions work and the more negative emotions and negative experiences occur. Fourth, personal characteristics have positive effects on job satisfaction in the moderating effects of intrinsic compensation and external compensation. There is a difference in job satisfaction due to intrinsic compensation and external compensation.

This study examined the possibility of applying the industrial accident insurance balance ratio to the calculation of the converted accident ratio in the credibility assessment of the PQ. Some correlations between the industrial accident insurance balance ratio and the converted accident ratio were found in the general tendency, however, there were no significant correlations between the two in the individual companies. Therefore, this study came to the conclusion that it is not appropriate to directly apply the industrial accident insurance balance ratio to the calculation of the converted accident ratio.
