본 연구는 2014년 12월 현재 노인장기요양기관이 국민건강보험에 신고한 임금자료 DB 즉, 공공데이터를 활용하여 요양보호사의 근로실태와 임금수준을 분석하였다. 2014년 말까지 요양보호사 자격증을 취득한 1,231.357명 중 본 연구는 확인이 가능한 1,221,085명을 대상으로 자료를 구축하였다. 이들 중 91.3%는 여성, 41.0%가 50~59세였다. 전체 자격취득자 중 요양보호사로 근무하는 인력은 약 14.8% 수준에 불과하였다. 취업 중인 요양보호사의 약 73.2%가 현 직장 근무연수가 3년 이내이며, 이들의 임금은 입소시설의 경우 월 129.2만원(처우개선비 포함 139.1만원), 재가기관의 경우 시간당 6,421원(처우개선비 포함 7,046원)이었다. 이와 같은 분석을 통해 본 연구는 요양보호사의 근로실태와 임금을 보다 구체적이며, 시계열적으로 파악하기 위해서는 입소시설과 재가기관을 구분한 분석뿐만 아니라, 처우개선비 효과에 대한 분석이 필요하다는 것을 제시하였다.

우리 건설 산업의 국가전체산업 대비 기여현황을 살펴보면 제조업 대비 45%정도의 종사인원이나 산업생산 유발계수가 제조업과 거의 대등하고 부가가치 유발계수는 제조업보다 훨씬 높다. 이러한 건설 산업의 현장생산직 근로자들이 겪고 있는 열악한 근로실태와 개인 삶에 대한 현황을 조명하여 우리사회 구성원으로서의 동반자로서, 또 건설 직업인으로서 긍지를 갖고 직무에 충실할 수 있도록 정부와 업계가 함께 노력하여, 그들의 위상을 강화시킴으로서 한 차원 높은 건설생산문화가 유발될 수 있고 업계의 세계화에 따른 경쟁력 향상에도 이바지하게 될 것이다. 이러한 건설생산직 근로자들을 위한 전문적인 교육 훈련, 신분보장, 자격제도 확립, 사회보험혜택, 안정적 임금수령, 작업환경개선 등 전문 직업인으로서의 자부심을 가질 수 있는 제도화된 환경을 통하여 그동안의 실적위주 정량적 건설에서 정성적 건설로 변화하는 기틀을 마련하도록 하여야한다. 우리나라의 행복지수는 100점 만점기준 67.8점으로 OECD 30개 국가 중 25위에 그친다. 건설현장 근로의 보다나은 양질화를 유도하기 위하여 현장생산직 근로자들의 직업 및 사회적 자기만족도 향상을 위한 대책으로서 기존관습에서 탈피하여 개선시켜야하는 문제요소들을 도출, 정부와 업계가 함께 노력하여 점차 세계화되고 있는 우리건설업계의 국제경쟁력에 이바지할 수 있는 차원 높은 건설생산인력으로 변화시킬 수 있도록 해야 한다.

Much studies have been concentrated to develop the fabrication technique for high critical current density but still there are a lot of gap which should be overcome for large scale application of superconducting materials at liquid nitrogen temperature. The improvement of the critical current can be achieved by forming the nano size defect working as a flux pinning center inside the superconductor. In this paper, the establishment of fabrication condition and additive effects of second elements were examined so as to improve the related properties to the practical use of superconductor.

A major change occuring in the workplace is the willingness of union leaders, managers, and workers to experiment with various work schedules and to work toward the improvement in the QWL(quality of work life). In this study, the writer measures the level of QWL, embodies components of QWL, testifies the difference of QWL according to the demographical traits, and develops some scales to measure QWL in merchant ships. To achieve objectives of the paper, 11 hypotheses were established and a questionnaire was used, 894 proper data was obtained from 2, 910 Korean seamen working in merchant ships. Results of analyses are as follows : 1) The components of QWL in merchant ships are job, employee satisfaction, wage, welfare, working condition, supervise, colleague relations, initiative, and organization management. 2) Seamen of merchant ships are satisfied with job, supervise, colleague relations, and organization management. They are dissatisfied employee satisfaction, wage, welfare, and working condition. 3) According to demographical traits, the number of the factors significant difference(P<0.05) among components of QWL are 9 for type of ships, 8 ages of seamen, 7 for married or single, nationality of ships, and education level respectively, 5 for seamen career, for 4 rank on board and trading route of ships respectively, 2 for whether union or not and whether union involvement or not respectively, and 1 for department on board. 4) Results which tested hypotheses are as follows : For the components of QWL, married men are more satisfactory than an unmarried men, officers are more dissatisfactory than ratings, old men are more satisfactory than young men, men in high education level are more dissatisfactory than men in low education level, those who are much careers as a seaman are more satisfactory than those who are little careers as a seaman. There are significant differences in the components of QWL according to nationality and type of ships. There are insignificant differences in the components of QWL according to the shipboard department, whether union is or not, whether union involvement is or not, and trading route of ships.

The objective of this study is to survey the working environmental conditions and musculoskeletal workload(DMQ) in red pepper farmers. 155 full-time farmers(males=91, females=64) lived in Chungnam and Jeonbuk participated in the study. To offer the fundamental data for agricultural improvement of red pepper farms, information about working farm conditions, health condition, musculoskeletal disorders(MSDs), labor intensity and musculoskeletal workload was obtained by questionnaire and interviews. The results are as follows: 1. The farmers reported sunlights, high temperature and cold/ draught as uncomfortable work environment. 2. Physical and mental fatigue in females is higher than that of males. 3. The prevalence rates of medical diagnosed diseases are higher in order of osteoarthritis, herniated nucleus pulposus(HNP), and chronic gastritis/gastric ulcer. 4. Prevalence rates of musculoskeletal symptoms more than standard 1 among the various pain areas are higher in order of low back, shoulders and knees. These results can be used practically for agricultural improvement of red pepper farms to prevent MSDs.

It is estimated that about 2,515 persons have been injured by conveyor for the past five years(2013 ~ 2017). Conveyors used in various industrial sites for transporting iron ore, coal, courier goods, etc., have various incidents such as a worker putting on or pulling a part of the body or work clothes on the driving part during maintenance. It is necessary for preventing similar accidents to conduct various researches. In order to propose the basis for revising laws and standards for the safety standards of the full cord switch to prevent conveyor accidents, this study compares Korea's Industrial Safety and Health Law (KISHL) with those of IEC, EN, Canada, and Australia. In addition, surveys of conveyor use plant and full cord switch domestic and foreign manufacturers was conducted. In this study, domestic and overseas related laws and technical standards compare and analyze to prevent conveyor accidents. In addition, we propose extension of safety certification for full code switch, establishment of safety inspection standard, and improvement of working method regulation through actual working condition investigation. It can be used as a basis for revising the occupational safety and health regulation and related notices, and thus contributing to enhancing the safe atmosphere of the conveyor business and improving the safety consciousness of the concerned persons.

Wind turbine, which is attracting part of the renewable energy and is researching continuously, is going to be large size for high efficiency. There is a yaw system rotating the nacelle, weighted about 600 tons, to be perpendicular with the wind direction blowing in the large wind turbine. The wind turbine is focusing on the reliability improvement because working environment effect is bigger than any other points and specially, the reliability improvement of the yaw drive is required by the customer because it is the key component of the wind turbine. Because of this, the establishment of criteria for yaw drive is required because yaw drive system is the part of the wind turbine closely related with ensuring the reliability. So, this study did the failure analysis of the yaw drive system, which is consisted with 10 sets of yaw drives through researching and analyzing the site conditions. Also this study designed the life test method based on the failure analysis and working condition of the yaw drive. To design the accelerated life test of the yaw drive, this study reviewed the torque, lubrication condition, and frequency of use and etc. Finally, this selected the torque as the acceleration factor which is affected mainly to the system and also, the test equipment was developed based on the requirement of the life and performance test.
