많은 인원을 필요로 하는 조선업은 선박을 건조하는 현장의 제품들이 복합 공정이면서도 중후장대한 특성을 가지고 있다. 이러한 선박을 건조할 때는 종사하는 작업자 간의 작업 내용에 대한 의논과 방법의 결정에 따른 경험기술의 활용도가 높다. 그래서 작업자별 작업 방법이나 기능의 차이가 많고 그 차이만큼이나 공정 진척이나 품질에 대한 결과도 다르게 나타나게 된다. 하지만 인력 집약도가 높은 조선소 작업인력이 퇴직이나 이직 등으로 발생되는 공백을 내국인으로 채우지 못하고 경험이 없고 소통도 어려운 외국인 작업자로 대체하고 있는 실정이다. 외국계 작업자의 경우 인건비가 낮은 중소기업이나 대기업의 하도급 업체에 고용이 되는데 중소기업의 특성상 기술력의 축적이나 안전작업을 위한 사전 직무교육 등에는 여유가 없어 제한된 기간 동안의 고용이나 단순 업무에만 종사토록 하는 등의 방법으로 활용해왔다. 그러나 외국계 작업자의 고용 비중이 높아지면서 전반적인 생산성의 한계와 불안전 작업에 대한 우려로 그 관심도 높아지고 있다. 외국계 작업자의 경우 생산 현장에서 이루어지고 있는 각종 안전관련 교육이나 행사, 동료간의 소통등에 소외되면서 불안전이 가중되고있고 비자종류에 따라 체류기간이 한정되어 기술력의 유지는 어려운 현실이 될 수 밖에 없다. 이러한 외국계 작업자에게 안전에 대한 수준을 높이기 위한 방안으로 직무별 위험성평가도 작업자의 논높이에 맞게 해야 한다. 현재 활용되고 있는 4가지 위험성평가 방법을 일부 보완하여 안전수준에 맞게 실시하여 작업자 개인별 직무 수행상의 위험성에 대한 이해도가 안전에 미치는 영향을 최소화 하여 안전을 유지시키는 방안을 연구한다. 위험성평가의 취지가 기본적으로 해당 작업자 전원참여라는 중요 요소임을 감안할 때 외국인 작업자의 직무 이해도 점검은 매우 중요하다 하겠다.

농촌생활의 질의 풍요로움을 연구하기 위한 일환으로 농가 생활경영을 시점으로 한 농업겨영과 농가주부의 관계, 가사운영과 가계관리를 중심으로 살펴 본 결과를 요약하면 다음과 같다. 첫째, 농업경영과 주부와의 관련에 대해 우선 열거할 수 있는것은 생산 노동력의 분담상황에서의 주부노동의 실태이다. 전체평균에서 78.1%의 주부가 남편과 함께 기간노동에 종사하고 있었으며, 농업생활에서 주부의 역할리 매우 큼을 단적으로 지적해 주는 것이었다. 그리고 종사하는 종작업과 경영 참여의 내용은 다양하다. 그 결과 시간적으로 본 주부 담당의 가사작업은 농번기와 농한기의 시기에 영향을 크게 받고 있음을 알 수 있었다. 둘째, 가계관리상의 문제점으로 자녀의 교육비나 교제비의 부담이 거론되었고, 수입의 불규칙, 빚과 부채의 부담이 큰 문제로 지적되었다. 셋째, 가정생활의 만족도, 지역생활의 만족도는 모두 만족과 불만의 중간을 보였다. 가정생활에서의 만족도에서 평균점 보다 낮은 항목은 가족 동반의 식사, 부부대화, 내구소비재의 순이었고, 지역생활환경에 관하여는 보건소, 병원에 관하여는 불만족스러운 대답을 보였다. 넷째, 농작업의 효율화 대책은 기계화, 조직화, 공동화, 작업의 계획화이었으며, 가사노동에 있어서는 "주부의 농작업 감량대책"과 함께 "가족의 협력에 의한 가사분담","가족이 신변의 것을 스스로 한다","가사작업의 계획화"등이 요구되어진다.

Maintenance on the water chamber of steam generator, the change of pressurizer heater, the removal of pressure tube feeder, and so on during outage in nuclear power plants (NPPs) has a likelihood of high radiation exposure to whole body of workers even short time period due to the high radiation exposure rates. In particular, it is expected that hands would receive the highest radiation exposure because of its contact with radiation materials. In this study, field tests on extremity dose assessment of radiation workers for contact works with high radiation exposure were conducted during the maintenance periods in Korean pressurized water reactors (PWRs) and pressurized heavy water reactors (PHWRs). In this field test, radiation workers were required to wear additional TLDs on the back and wrist, and an extremity dosimeter on fingers including a main TLD on the chest, while performing maintenance. As a result, it was found that the equivalent dose for fingers was distributed in the fixed range of deep dose and the equivalent dose for wrists.

This study systematically analyzes job descriptions of hotel banquet service employees using DACUM. The expert group involved in the content analysis was comprised of 6 F&B managers working at deluxe level hotels. The period for this study was from May to June in 2010, and a group interview, an individual self fill-out together with a personal interview were carried out. Findings from the analysis were as follows; job duties for hotel banquet service employees extended to pre-task, on-task and post-task for each banquet function, safety management, guest encounter and self development. They included 49 specific job tasks which were divided into 5 different categories; 16 pre-task, 13 on-task, 10 post-task, 4 safety management and 6 guest encounter and self development It is suggested from the findings that advance training should be carried out for pre, on and post tasks.

Purpose: This prospective study was conducted to reveal the haematological index change by low level radiation exposure in radiological environment our hospital workers. Materials and Method: We gathered the cumulative dose by Thermoluminenscent Dosimeters (TLD) over 9-yr period and examined hematological index counts change (RBC, Hb, Platelet, WBC, Monocyte, Lymphocyte, Neutrophilic, Basophilic, Eosinophilic) both occupational workers and controls. Of a total 370 occupational workers and 335 controls were compared. Results: This analysis has led to the following general observations 1) The average cumulative dose in male and female were $9.65{\pm}15.2\;mSv$, $4.82{\pm}5.55\;mSv$ respectively. 2) In both male and female, there were very low relationship between occupation period and cumulative dose (r< ${\pm}0.25$). 3) Occupation period was more increased, in male, WBC counts decreased and increased workers, RBC counts decreased workers were more than controls group (p<0.05). In female, WBC counts decreased and increased workers and W-eosino counts decreased workers were more than controls group (p<0.01). 4) Cumulative dose was more increased, in male, W-Lympho counts decreased workers and Platelet counts deceased workers were more than controls group (p<0.05). In female, W-lympho counts decreased workers and RBC counts decreased workers were more than controls group (p<0.05). Conclusions: We can find some kinds of blood index abnormal distribution in occupational radiation workers by comparing with controls. Occupational workers cannot avoid radiation exposure, in spite of the control it. Actually low level radiation adverse effect occurred not dose but probability. So workers must always try to reduce exposure by ourselves, furthermore as long as possible the government should provide rapidly that national system on radiation control for worker's health.

In this study, we analyzed the effects of radiation exposure, as compared to the hematological parameters change of medical radiation workers and the public. The mean value of all hematological parameters were in the normal range. Eosin mean value of the radiation workers($2.52{\pm}1.79%$) showed that a significantly lower than the control group($2.92{\pm}1.39%$). In the comparison of the results depending on the occupation period, it showed high value that the mean of the radiation workers group WBC, platelet, Lymph, Mono, Baso. Over 20 years of radiation workers WBC, Mono showed low values and less than 10 years of radiation workers mean value of Baso showed low values, there was no statistical significance. In the comparison of the results depending on the 4 years cumulative radiation dose, Over 5.0 mSv of Radiation works RBC($4.61{\pm}0.53$ vs $4.91{\pm}0.38$), Hct($41.51{\pm}4.07$ vs $43.97{\pm}3.40$), Eosin($1.74{\pm}1.14$ vs $2.92{\pm}1.39$) showed low value, it was statistical significance. 0.5~1.0 mSv radiation exposure workers Hb ($13.93{\pm}1.75$) showed a significantly lower value than that of the control group ($14.90{\pm}1.29$).

The purpose of this study was to examine safety accidents related to school foodservice, working and operating environments of school foodservice, status and awareness of safety education, educational needs, and information on qualitative improvement of school foodservice. The subjects in this study were 234 cooks in charge of cooking at elementary and secondary schools in Chungbuk. A survey was conducted from July 30 to August 8, 2012, and among 202 questionnaires gathered, 194 completed questionnaires were analyzed. Statistical analyses were performed on data utilizing the SPSS version 19.0. The main results of this study were as follows: 44.3% of workers experienced safety accidents. The most frequent safety accident was 'once' (60.5%), and most safety accidents took place between June and August (31.4%). The time at which most safety accidents happened was between 8 and 11 am. Most safety accidents happened during cooking (52.3%) and while using a soup pot or frying pot (52.4%). The most common accidents were 'burns', 'wrist and arm pain', and 'slips and falls'. Respondents who experienced safety accidents replied that 57.6% of employees dealt with injuries at their own expense, and only 35.3% utilized industrial accident insurance. In terms of the operating environment, the score for 'offering information and application' was highest (3.76 points), whereas that for 'security of budget' was lowest (1.77 points). As for accident education, employees received safety education approximately 3.45 times and 5.10 hours per year. Improving the working environment of school foodservice cooks requires administrative and financial support. Furthermore, educational materials and guidelines based on the working environment and safety accident status of school foodservice cooks are required in order to minimize potential risk factors and control safety accidents in school foodservice.
