Job-appropriate personal protective equipment(PPE) is important for decreasing the high rates of occupational injury experienced by construction site. Objective: This analysis describes Personal protective equipment payment methods improvement by revision of occupation safety&health acts. Methodes: Data are show up during the past 9 year statistics for occupation injury cases from actual construction site in Korea construction company. Results: Most construction workers are not wearing PPE because of non-payment of PPE by employer mainly small enterprises. Conclusions: Construction site workers should be buy with job appropriate PPE themselves. Buying of PPE is essential in the near future and government should be provide appropriate compensation for self-buying action such as raise retirement deduction installment or raise of industrial accident insurance.
엔진 시 운전 후 엔진 내부 주요 부품 상태를 검사하기 위해 분해하는 작업을 엔진 개방 작업 공정이라 하는데 엔진 개방 작업 공정 중 콘 로드 분해 시간이 평균 대당 187.8분으로 표준 시간 90분을 과도하게 초과하여 시급히 개선이 요구 되어 현상파 악, 원인분석, 대책수립 및 실시를 하여 개선 후 86.7 분으로 감소하여 생산성 향상으 로 인한 원가절감을 연간 4200만원 달성하였다.
Because the lens is a tissue with the highest sensitivity, the lens shielding is very important in CT imaging. However, in clinical terms, there is a lack in the efforts in decreasing dosage on the lens, and the shielding of dosage and the effects on the imaging are researched using bismuth to evaluate the usefulness. As results of the dosage evaluation results, when there is no gantry angle when the thickness of the lens shielding material is 0mm, the dosage was 28.476mGy, and when there is gantry angle, the dosage was 20.852mGy that it was confirmed that the dosage was 27% lesser with gantry angle. It was confirmed that the dosage value decreased with the increase of thickness of lens shielding material when there is gantry angle, and when the lens shielding material was 1mm, the dosage decreased by approximately 39% compared to when it was 0mm. When there is gantry angle, the dosage values were respectively 12.788mGy and 12.776mGy for the crystalline lens shielding material thicknesses of 0.75mm and 1.0mm. In image analysis, the quantitative evaluation and the qualitative evaluation were almost constant regardless of the thickness of the lens shielding material. The optimal lens shielding material thickness to minimize the does of lens and increase the value of diagnosis in Brain CT examination is 0.75mm. Therefore, if this is utilized for easier use in clinical practices, it is considered to be able to contribute to not only the protection of the lens but the accurate diagnosis of diseases.
Currently, the construction industry in Korea implements the risk assessment that is implemented by managers and working team leaders. However, it is difficult to share the result of risk assessment meeting to substructural workers in korea system and the workers don't understand meaning and effect about risk assessment. The risk assessment is that the workers in the construction site have to know risk factors and reducing ways to the risks. But, the education and sharing methods for risk assessment system is insufficient in korea. For this risk assessment problems identified were surveyed. In order to improve the problems of the risk assessment, proposes the following three methods. First, Implement to educate the risk assessment during the basic safety and health training of construction industry. Second, the training way about workers' participation in risk assessment is necessary. For example, after watching videos, etc, the workers create risk assessment in person and make a presentation about it. Third, the risk assessment utilize during TBM(Tool Box Meeting). Before working every day, we need to educate risk factors and the reducing ways to the risk during TBM.
도시철도 기관사는 일상적 교번근무의 제도적 틀에 따른 심리적, 신체적 피로와 긴 장감을 경험하는 한편, 사고 및 장애발생의 가능성을 늘 염려하면서 주어진 과업을 수 행해나가고 있다. 즉, 이들은 항상 이례상황의 발생가능성을 염려하면서 과도한 스트 레스를 느끼게 되는데, 이는 공포불안과 분노혐오라는 부정적 정서를 유발시키는 원인 이 된다. 이 같은 부정적 정서는 기관사의 일과 삶의 균형에 상당한 손상을 주는 요인 이 된다. 본 연구는 도시철도 기관사의 이례상황 스트레스가 기관사의 정서와 일과 삶의 균 형에 미치는 부정적 영향을 살펴보고 이 같은 일련의 관계에서 기관사의 이례상황 스 트레스를 완화하고 일과 삶의 균형을 제고할 수 있는 제도적 방안이 무엇인지를 살펴 보는데 주된 목적을 두었다.
CIS nations are recognized as a emerging market recently because there are abundant natural resources and a lots of investment demand. Furthermore, they are located in the middle of Europe and Asia and that make them have more strategic importance as a logistics hub. So many global companies including domestic ones began to advance into the on-site. and henceforth this tendency will be strong. On the contrary, a research in logistics environment of CIS has rarely been done. This paper provides a way of systematic approach to design logistics network in CIS with real business case and shows the analyzed result of optimization simulation that includes factors have a huge influence on the overall logistics cost.
본 연구에서는 플랜트 공사 저장탱크 붕괴 사고사례 원인에 대한 연구를 수행하였다. 저장탱크란 기 름, 물, 가스 기타 약품등과 같은 유체를 효율적으로 저장하기 위하여 인공적으로 만들어진 지상의 저장 시설을 총칭해서 말하는데, 일부 업체들은 군집된 저장소(Tank Farm)를 보유하고도 있다. 저장탱크 시 공 방법을 보면 저장물의 성분 및 종류에 따라서 탱크 종류가 결정되는데 대부분 작업이 중량물을 건설 중장비를 동원하여 높은 곳에서 이루어지는 작업 형태를 갖추고 있어 일반 공종 작업에 비해 훨씬 많은 위험 요인을 내포하고 있는 실정이다. 최근에 들어 저장탱크 붕괴 등의 중대한 사고가 빈번하게 발생하 는 바, 구조물 특성상 자칫 대형 인명사고로 발전하는 경우가 많다. 본 발표에서는 최근 들어 발생한 저 장탱크 붕괴 사고사례을 통하여 이에 대한 원인을 파악 하고자 한다.
