Phenothiazine의 직업적 노출기준(TLV-TWA)은 $5mg/m^3$으로 권고되었다. TLV-TWA의 수준은 피부자극과 변색, 각막염 그리고 태양광에 직접 노출되었을 때 나타나는 광감작반응의 가능성을 최소화하기 위해 설정되었다. 고용량의 phenothiazine을 경구 투여하면 간과 신장이 손상되며 용혈성의 빈혈이 발생한다. Phenothiazine의 피부흡수에 의한 전신 독성이 증명되어 피부흡수 "Skin" 경고주석을 권고하였다. 감작제(SEN)와 발암성 경고주석 그리고 TLV-STEL을 설정하기에는 유용한 자료가 부족하다.

This study is a retrospective and descriptive research to identify the factors affecting development of spontaneous abortion in women of childbearing age. The subjects totaled 198 females aged 20~45 who had experienced childbirth or spontaneous abortion at least once, and data was collected for one month since July 2019 through self-reporting questionnaires. The results showed that the factors affecting development of spontaneous abortion were use of panty liners (daily: reference, 1~2 times a week: B=-1.74, no: B=-0.77) and antimicrobials (often or a lot: reference, small or normal: B=-0.71, no: B=0.79), occupational groups (inoccupation: reference, service industry employee: B=0.73, white collar: B=1.22, professional: B=0.63, manager: B=1.54), and exposure-risk behavior toward endocrine-disrupting chemicals (B=0.81) during pregnancy, and their explanatory power for development of spontaneous abortion was 24.4% (R²=.24). As a result, it is necessary to prevent endocrine-disrupting chemicals exposure and pay attention to the occupational environment during pregnancy in order to reduce the development of spontaneous abortion.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.

대부분의 사람들에게 변화는 어렵거나 불편한 것이다. 익숙하지 않다는 것이 사람을 불안하게 하며 아무도 이런 불안감을 좋아하지 않는다. 새로운 환경과 새로운 경험은 매우 흥미로울수도 있지만 모르는 것을 접하게 되면 어느 정도 불안감을 느끼게 된다. 현재 게임 산업은 보다 큰 타 산업시장과 마찬가지로 다소 불안정하다. 대부분 직업은 불안정하며 능력 향상을 원하거나 프로젝트가 종료되었을 때 어떤 경우에는 직업을 불가피하게 변경해야 한다.

This study analyzed how North Korean defectors recognized and overcame conflict in the South Korean job culture during the course of entering and settling into South Korea, and the association between their old career and adaptation within their new careers. The study selected 13 employed participants who entered South Korea more than five years ago and experienced working. Interviews were conducted over the course of five years. The topics were analyzed after performing interviews 60 to 120 minutes long by recording and transcribing the recordings and using semi-structured questionnaires for the 13 people. The results reflected the job environment in North Korea, their career background, factors for a successful new life, their constant efforts for employment, the difficult adaption to South Korean life, pursuing job stability, accepting South Korean culture, and career compromises. The results of this study are as follows. First, they undergo difficulty in the course of selecting jobs due to the converted environment from passivity to autonomy. Second, they cannot use their previous job history and they complained about prejudice and the lack of job information. Third, major problems included their lack of adaptability, stress, and loss of economic power. The study suggests that these North Korean defectors undergo an integrated course of cultural learning. Fourth, they were hardly able to adapt. Fifth, they tried to overcome conflicts of job culture according to their personal characteristics.

This study is to develop a competence model for school principals that provides effective career and vocational education (CVE) at middle schools. This model can be used as an indicator for identifying the expertise levels of principals in CVE and to help them develop the necessary skills. Research methods included literature review, basic research, the Delphi technique, analytic hierarchy process (AHP), and surveying. The results were as follows. The competence model for CVE for middle school principals consisted of three competence groups, nine competence elements, and 67-item behavior indicators. First, the three competence groups included the competence to build a school system for CVE, the competence to support CVE at school, and the competence to create a school environment for CVE. Competence to support CVE at school turned out to be most important in the AHP analysis. Second, competence elements included goal management, performance management, the creation of educational culture, support for educational activities, support for school curriculum, support for students, human resources management, resource management and community management. According to the AHP analysis, support for school curriculum was the most significant among the nine competence elements. Third, the behavior indicators were identified items in three areas: 18 items for individual propensity, 18 items for knowledge, and 31 items for performance.

The aim of this study was to examine self-efficacy and work ethic on the moderating effect of retraining program for personal assistants to influence job environments and job satisfaction. The data were obtained from 330 personal assistants working at the Personal Assistance Association of Gyeonggi-do. The data were analyzed using the Structural Equation Modeling with relative effect analysis. The result of this study showed that self-efficacy and work ethics should have an impact job environments and job environments should have a positive impact job satisfaction. The retraining program for personal assistants showed a moderating effect on the relationship between work ethics and job environments. However, the findings did not support the moderator effect on the retraining program for personal assistants in the relationship between self-efficacy and job environments. Using these findings, social work administration agency, in particular, can be guided in terms of human resource management under social work administration.

Objectives: Formalin is used as an anthelmintic in farms where flounder are raised. In this study, we aim to identify formaldehyde exposure levels for aquaculture industry workers and provide basic data for managing formaldehyde exposure. Methods: Exposure levels of formaldehyde in the air, including formalin spraying operations, were assessed separately for personal and area samples. In addition, considering the formalin administration method, dermal exposure to the hands was estimated when administering the chemical, and dermal exposure to the legs during water tank work was estimated by collecting water in the water tank and evaluating the amount of formaldehyde remaining. Finally, the respiratory exposure level and the estimated dermal exposure level were added to derive the total exposure level and compared with the maximum allowable human dose. Results: As a result of the airborne evaluation, the formaldehyde concentration of the worker (1 person) who performed the formalin spraying and flounder sorting was 33.61 ppb, and the arithmetic mean of formaldehyde concentrations of the workers (3 people) who only performed the flounder sorting was 3.28 ppb (range: 2.25-4.89 ppb). In the case of dermal exposure, when spraying formalin once, the amount was estimated to be 0.33-2.62 mg when wearing protective gear and 3.27-26.12 mg when not wearing it. Conclusions: There was a difference in the formaldehyde exposure level of workers depending on their operation of handling formalin and whether or not protective gear was worn. In particular, because the level of formaldehyde exposure due to dermal exposure can be significant, there is a need to improve formalin administration methods in a way that avoids skin contact as much as possible.

It is difficult to improve maritime safety in the aspect of human elements without seafarers' job satisfaction. Therefore, through the career development for seafarers from their entries into the job to their retirements, longer and more stable seafarers' life on board ship could be achieved together with maritime safety. This study aims at the establishment of seafarers' career path model and the verification of six hypotheses by using the questionnaire data of 2,830 respondents of students, slip officers and shore-based ex-seafarers. The results of analyses of behavior factors on the career path are as follows; first, it is important to improve educational environment and to provide seafarers with detailed information on seafarer's life; second, economic factors such as income-level and etc. do not play a role in promoting motivation of going to sea; third, the guidance to shore jobs at proper time increases seafarers' job satisfaction and induces longer stay at sea; last, it is necessary to simplify the licence system for seafarers, to allow seafarers to acquire higher class certificates, and to work at higher rank on board ships as early as possible.
