Ergonomic intervention techniques were adopted to assess and control potential risk factors of work-related musculoskeletal disorders(WMSDs) in the automated light assembly manufacturing system. Ten different kinds of assembly workstations implemented with a conveyor system and twelve female workers were observed and evaluated with careful video film analysis. Several close examinations using sets of checklists established by qualified safety and health organizations, such as NIOSH, OSHA, and ANSI, were conducted and every workers and staffs in the site participated in the self-report questionnaires and off-line interviews. Typical risk factors and symptoms of the upper extremity musculoskeletal disorders were found and categorized into specific parts of body. To reduce risk factors of WMSDs and improve system productivity new revised workstation standards, physical dimensions, were suggested accordant with anthropometric characteristics of workers and a heuristic decision strategy of rotating shift work schedules according to work contents has proposed to mitigate cumulative physical stress. Finally, ergonomic programs of entire company to prevent WMSDs were structured.

The purpose of this welding process of the exclusive welding-machine using welding torch-rotation type is to develop a mechanism which can solve the problem of twisting of welding wires and cables. The technique was developed by revising the torch position and smooth controlling of both the normal and reverse rotation. Some of the advantages of using the torch-rotation type apply to the work-rotation technique are the practical uses of increased work space and link work with the factory automation system. Do apply the welding process, I designed and made a special unit so called torch part in order to solve the problems of kinematical. And I made a control panel which can manipulate the progress of the entire process at the work shop. Even if it will be applied to another kind of axle casing's welding work, this process can be utilized if other sizes of the fixed pin and work part is produced and changed. The development of this exclusive welding-machine could reduce the manpower of skilled welding labor and increase productivity and better quality product in comparison to the handmade product.

공정 및 작업단위등이 다양하고 복잡한 건설산업에서 작업일보의 관리는 매우 중요하다. 그러나 건설산업 분야의 다양한 건설프로젝트 관리 시스템은 작업 및 작업시 발생하는 정보들을 효율적으로 관리하지 못할 뿐만 아니라 하수급업체와의 연계가 되지 않아 실제적으로 이용되지 못하고 있다. 이것은 하수급업체에 대한 배려 없이 원수급업체 주도로 시스템이 구축/이용되기 때문이다. 이러한 이유로 하수급업체 중심의 시스템이 발전하지 못할 뿐만 아니라 프로젝트 진행에 있어서 발생하는 작업정보의 축적에 있어 누락 및 왜곡이 발생하는 문제점이 발생하고 있다. 따라서 본 논문의 목적은 웹을 기반으로 원수급업체와 하수급업체간 원활한 작업정보 관리 시스템의 개발에 관해 연구/분석하고 모델을 제시하는데 있다.

In forest work, working conditions are very hard to improve. The good posture is believed to bring about direct improvements such as accident prevention. Therefore, this research carried on analysis of working posture in forest work (construct in stepping-stone) using OWAS analysis system. According to the analytical results provided by OWAS, the ratio of category III (Work posture has a distinctly harmful effect on the musculoskeletal system) has shawn that worker 2 was 32.2%, worker 1 was 25.2% and worker 3 was 15.5%. Furthermore, the ratio of category IV (Work posture with an extremely harmful effect on the musculoskeletal system) has shown that worker 2 was 9.8%, worker 3 was 1.4% and worker 1 was 1.2%. According to the OWAS method, percentage of OWAS action categories III and IV in the worker 2 was higher than another workers.

이 연구는 공공부문 스마트워크센터 사용자에 대한 AHP 설문을 이용하여 정책의 지속적 사용 및 확산을 위한 우선 정책 과제를 도출하고, 분석결과를 토대로 대응 방안을 모색하는 것을 목적으로 한다. AHP 설문을 위한 정책과제의 대분류는 기술 인프라 개선, 제도 개선, 인식 개선의 세 가지로 구성하였다. 기술 인프라는 스마트워크 기술개선과 스마트 워크 시설개선으로, 제도 개선은 법제도 개선과 추진체계 개선으로, 인식개선은 조직문화 개선과 사용자 인식개선으로 각각 중분류하였다. 총 12개의 정책과제 중 조직문화 개선이 중요성과 긴급성 측면에서 가장 우선적인 정책과제로 분석되었으며, 인사복무규정 개선, 정책결정자의 리더십, 사용자의 인식 개선 과제 등이 우선적으로 해소되어야 할 것으로 나타났다.

With the development of Information Communication Technology and a way of solving problems such as productivity improvement, advanced working attitude, greenhouse gas reduction, low birth rate, aged problem, etc., the need of smart work is increasing. Getting out of legacy working types that are limited in time and space, the flexible seat system at a smart work center that supports the smart working environment is proposed. However, the seat choice based on employee's emotional judgement may cause the decline of forming cooperative space and mutual communication because of the scattered seat arrangement between employees. This paper proposed a seat recommendation method for the mutual cooperation at a smart work center. The method is based on a work similarity of employees. A prototype system also implemented to show the feasibility.

In the current age of the information oriented society in which we live, many people use PCs and are dependant on the databases provided by the network server. However, online data can be missed during the occurrence of a blackout and furthermore, power failure can greatly effect Power Quality. This has resulted in the trend of using interruption-free live-line work when trouble occurs in a power system. However, 83% of the population receives an electric shock experience when a laborer is performing interruption-free live-line work. In the interruption-free method, education and training problems have been pinpointed. However, there are few instructors to implement the necessary training. Furthermore, the trainees undergo only a short training period of just 4 weeks. In this paper, to develop a method with no restrictions on time and place and to ensure a reduction in the misuse of materials, immersion type virtual reality (or environment) technology is used. The users of a 3D immersion type VR training system can interact with the system by performing the equivalent action in a safe environment. Thus, it can be valuable to apply this training system to such dangerous work as 'Interruption-free live-line work exchanging COS (Cut-Out-Switch)'. In this program, the user carries out work according to instructions displayed through the window and speaker and cannot perform other tasks until each part of the task is completed in the proper sequence. The workers using this system can utilize their hands and viewpoint movement since they are in a real environment but the trainee cannot use all parts and senses of a real body with the current VR technology. Despite these weak points, when we consider the trends of improvement in electrical devices and communication technology, we can say that 3D graphic VR application has high potentiality.

We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.

최근 국내 외적으로 크랙실링 공법의 활용성을 높이기 위해 도로면 크랙실링 자동화 장비 개발에 관한 연구를 활발히 진행하고 있다. 예방적 차원에서 도로의 장 수명화 및 유지보수 비용 절감을 위해서는 도로 유지관리 시점 및 유지 보수된 구간정보, 작업 수행 결과 등과 같은 이력정보가 체계적으로 수집.축적될 수 있는 관리체계의 개발이 선행되어야 한다. 그러나 기존 크랙실링 관련 기술개발 동향은 크랙실링 공법의 자동화를 위한 연구가 주로 수행되고 있을 뿐 도로면 크랙실링 작업정보 수집과 관련한 연구는 미흡한 것으로 나타났다. 따라서 크랙실링 작업 관련 정보습득의 어려움 및 경영 분석과 성과측정을 위한 객관적인 자료 구축 미흡, 수집된 정보의 신뢰성 부족 등과 같은 문제점이 도출되었다. 본 연구에서는 크랙실링작업 시 발생되는 정보를 신속.정확하게 수집 및 축적하여 이력관리로 활용하고 작업 주체간의 정보교류를 효율적으로 수행할 수 있도록 지원하는 PDA 및 웹 기반 크랙실링 작업정보 수집 시스템을 제안하고자 한다.
