As contemporary building construction type is getting higher and deeper, construction equipment usage is getting more, and related fatal accidents are on an increasing trend. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using "smart phone" base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn't know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.

As contemporary building construction type is getting higher and deeper,construction equipment usage is getting more, and related fatal accidents are on an increasing trend. In these days, due to the deteriorating construction business circumstance, job finding problem of equipment operator, and dumping contract, equipment lease suppliers are putin jeopardy. In high-rise building construction, especially tower crane, mobile elevated work platform and other High place operation cars among construction equipment cause many critical accidents because of drop supply of construction biding bringing out dumping contract could cause unsafe and poor construction management. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using ‘‘smart phone’ base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn’t know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.

Risk Assessment, a basis of health and safety management system, is an calamity prevention activity which regularly measure the level of a risk to passively improve potential hazard. A problem, the assessment not being improved to be applied to the construction work site where requires diversity and complexity, causes the assessment to be inefficient to bring quality results. A study on the investigates and compares the surveyed degree of recognitions of workers who works in companies executing the risk assessment By the investigation and comparison, it is expected to bring the better solution for early and efficient application for those companies which are not taking the risk assessment.

It is known that human factors account for 80 percent of all railway accidents. To reduce human errors must be the most efficient shortcut to railway safety. For public transportation employees like railway, the more delicate safety management should be executed in individual level. However, there are rarely efforts to improve safety performance of workers who are the subject operating the railway system. This paper develops a hierarchy model to evaluate the human safety performance in railway industry. To evaluate the model, AHP (Analytic Hierarchy Process) methodology is adopted. The hierarchy model is composed of four levels which are objective, two criteria, specific factors of criteria, and rating scales. In addition, since employees for evaluation are over 10, the pairwise comparisons for rating scales are carried out by the absolute measurement. We explore the applicability of AHP to the performance evaluation of railway safety workers by an example and also investigate the changes of alternatives that are railway employees according to the changes of human characteristic which is one of criteria.

This paper was concerned about case study for preventing WMDSs(Work-related Musculoskeletal Disorders) by using Thinking Process of TOC(Theory Of Constraints), Unfortunately, the number of WMDSs are rising steadily in auto-part manufacturer. These WMDSs have on worse and worse influence not only on the competition of enterprise but on the life quality of a worker. The research results are helpful to establish the preventing WMDSs and improvement of workplace environments for small-medium sized auto-part company.

A study is for the approach that we could reduce the logistics costs through uprising the efficiency, complying to the demand in time, stock management based on the general production plan in the point of SCM. We will take following steps to get the goal. First, we will overview the physical distribution expenses annually. Second, will find the main cause of optimal load loss by improper container and lack of delivery flexibility to the demand. Third, the goal will be inferred through the fast information share based on organic relationship, the establishment of general production plan, the improvement of stock management plan. By way of this process, it can be accomplished expense reduction as well as flexible establishment of the reduction of worker's load.

2002년 7월 PL(Product Liability; 제조물책임)법이 시행된 이후 정부에서는 ‘소비자보호 종합시책’을 확정하고, 업종별 PL센터를 설립하여 소비자상담과 분쟁에 적극 대응하고 있다. 특히, 중소기업청에서는 기술지원과 함께 법률지원단을 구성 운영하고 있으며, 대기업에서는 PL법 집단소송제 등에 대응하기 위하여 법무 팀을 강화하고 있다. 그러나 아직 많은 경영자들이 제품고유의 안전성 확보를 위한 철학과 기술을 가지고 있지 못하여 제조물책임법에 대한 대응체계가 미흡한 것이 사실이다. 본 연구의 목적은 제품개발에서부터 설계, 제조, 출하, 폐기 등 전 제품수명주기 동안 기업이 제품의 안전성을 제고하고, 총체적 제품안전경영을 할 수 있도록 현행 업무프로세서에 대한 개선방안을 제시하는데 있다.

산업재해의 직접적인 원인은 작업자의 불안전한 행동과 작업과정에서의 안전시설 설치미흡으로 인한 불안전한 상태로와 기술적, 교육적, 관리적 원인의 복합적인 형태로 발생되는데 그 가운데 산업안전보건법상의 건설공사 각 공종 별 기술적인 안전시설설치 기준이 건설업 종사자에게 쉽게 적용하기가 현행 법기준에는 문제점이 있으며 이러한 복잡한 법기준을 분석하여 안전사고 예방 기법에 적용하고자 제시하고자하며, 향후에 이를 바탕으로 산업안전보건법상의 안전기준을 체계적으로 분석하여 제시하고자 한다.

전자해도 시스템은 2012년 7월 1일 부로 국제항해에 종사하는 선박에 단계별로 설치가 강제화 되었다. 전자해도시스템은 백업장치 를 비치할 경우 종이해도를 대체하여 사용할 수 있는 설비로 선교에서 사용의존도가 높은 핵심항해설비라고 할 수 있다. 현재 전 세계적으로 전자해도 시스템 이용 시 다양한 오류가 발생하고 있으며, 국제해사기구 및 국제수로기구에서도 문제를 인식하고 오류해결을 위한 방안을 모색 하고 있는 중이다. 본 논문에서는 선장 항해사를 포함하는 사용자들을 대상으로 전자해도시스템의 이용 시 오류 발생현황과 정보표시 및 주요 기능 이용 시 개선 요구사항에 관한 설문을 시행하였다. 그 결과를 기반으로 항해안전과 효율측면에서의 ECDIS 기능 개선사항을 제시하였다. 조사에서 사용자들은 ECDIS 기능사용에 있어 대부분 효율성 측면에서는 긍정적으로 평가하였으나 항해안전성에 대한 불안감을 많이 느끼는 것으로 나타났다.

런칭거더를 이용하여 상부구조를 가설하는 건설현장에서 런칭거더가 붕괴하여 인접하는 상부구조 및 하부구조에 일시적인 큰 충격하중을 가하므로 인하여 손상이 발생되었다. 따라서 손상이 발생된 상부구조와 하부구조의 건전성을 평가하여 장기적인 안전성 및 내구성을 확보할 수 있는가를 평가하기 위하여 정밀안전진단을 실시하였다.
