A number of screening tools have been developed to evaluate the human balance capability. Many of them were designed to identify the elderly with falling risk. Three different screening tools, which have been well used many clinical fields, were used in this study. The purpose of this study was to evaluate balance capability in facilities maintenance workers in korea. There were no statistical significance between male and female when evaluated with three different screening tools. However, significant differences were found among the age groups irrespective of gender when evaluated with three different screening tools. The results of three different screening tools in korea showed poor values compared with previous results. These results revealed that facilities maintenance workers faced more critical falling risk in korea.

Educational facilities have an affect to make a decently learning environment. After constructed, it needs a maintenance plan to keep the performance or function which provide the repair time, repair scope and ratio. But the fundamental data are so insufficient that the field worker can't provide the maintenance plan and has no choice use the other data which concerned with apartment or office building. Above all, the service life is indispensible to make a repair plan because the repair time and scope would be provided within the service life. This study aimed at providing the method to make a service life of component in educational facilities and applying the method into the roof proof and floor finishing. Results are shown that first, it is important to set the $1^{st}$ repair time after constructed. when it proposes the three ways with the probability approach, choice probability model and cumulative cost function. Second, the service life of roof proof is provided with about 35 years. In addition, the service life of the floor finishing is about 40 years. These result would be utilized to conduct the repair plan under the service life.

This paper is described that advanced study on network design of remote diagnosis system for power facilities of electric railway. In the field, it is very difficult for worker to diagnosis power facilities including catenary because workers should be maintenance on AC power supply. Therefore, to properly design on remote diagnosis system, we have searched the inside and outside of the country-related technology trends. Also we confirmed that required technologies to design interface technology required for the development of sensor devices and the USN network was designed in accordance with required skills. Throughout variety of requirements, we have development iRFS based ZA sensors and iRFM to receive data of sensor. Also CC2420 is applied as single-chip which used 2.4GHz IEEE802.15.4 compliant RF tranciver designed for low-power and low-voltage wireless applications for ZigBee communication.

Personnel maintaining or repairing the railway tracks or signaling facilities around tracks may experience the sensory disorder when doing maintenance works at the trackside of railway for long time. In this case personnel maintaining at the trackside may collide with the train since they cannot recognize the approach of motor-car although it approaches to the vicinity of maintenance workplace because of the sensory block phenomenon occurred due to their long hours of continued monotonous maintenance work. In order to prevent such motor-car accidents that may occur because railway track workers are unable to recognize the approaching train, the safety alarm equipment is developed to make the approaching motor-car send radio signals and bidirectional detection mechanism between approaching train and trackside personnel. It shows the possibility of utilization in various forms of safety equipment for workers only to the safety helmet to be worn by the maintenance workers while using the configuration of transmitting/receiving sides. In the paper it is represented new alarm equipment, which is the bone-anchored speaker-based safety helmet to be worn by the maintenance workers.

The purpose of this study is basic research for demand forecasting of residence which will form in the new industrial complex. Our industrial complexes are important base of National economic development until 90's. But The industry complexes which confront facility which is old, Maintenance negligence and change of industrial system must change new shape from existing function of industrial complexes. The results of this study are that the present housing using condition are different at ages and Using intentions of staff facility are negative generally. These means that When starting the structure hightening, the utility system provision and public information of residence facilities in industral complex are necessary for workers. So, The key points of industry complex structure hightening are that the accurate recognition about demand and the development of financial support policy for young Income low-end workers do to make advance efficiently.

Objectives: The aim of this study is to critically review the exposure surrogates and estimates used to associate health effects in wafer fabrication workers such as spontaneous abortion and cancer, as well as to identify the limitations of retrospective exposure assessment methods Methods: Epidemiologic and exposure-assessment studies of wafer fabrication operations in the semiconductor industry were collected. Retrospective exposure-assessment methods used in cancer risk and mortality and reproductive toxicity were reviewed. Results: Eight epidemiologic papers and two reports compared cancer risk among workers in wafer fabrication facilities in the semiconductor industry with the risk of the general population. Exposure surrogates used in those cancer studies were fabrication(vs. non-fabrication), employment duration, manufacturing eras, job title (operator vs. maintenance worker) and qualitative classifications of agents without assessing specific agent or job-specific exposure. In contrast, specific operation, job title and agents were used to classify the exposure of fabrication workers, contributing to finding a significant association with spontaneous abortion (SAB). Conclusion: Further epidemiologic studies of fabrication workers using more refined exposure assessment methods are warranted in order to examine the associations between fabrication work, environment, and specific agents with cancer risk or mortality as used in SAB epidemiologic studies.

건설현장에서는 많은 사진이 촬영되나, 촬영된 사진들에 대한 6하원칙 정보가 효율적으로 관리되지 못하고 있다. 이로 인하여, 건설경험과 지식이 없는 경우에는 의사소통이 용이하지 않고, 이해관계자간의 협의, 분쟁, 시설물 유지관리, 다른 시설물 건설 등에 촬영된 사진정보가 활용되는데 한계가 있었다. 본 연구에서는 촬영된 사진과 6하원칙 정보가 결합된 벡터사진의 필요성을 제기하고, 벡터사진 생성 및 서버저장 모듈의 프로토타입을 개발하였다. 촬영된 벡터사진은 실시간으로 서버에 저장되고, 6하원칙정보에 의해 DB 시스템에서 효율적으로 관리될 수 있다. 향후 벡터사진과 BIM모델을 연계하는 시스템을 개발하면, 사진 속의 벡터정보를 BIM모델의 객체 속성정보와 연결시킬 수 있게 되어, 벡터사진은 더욱 다양한 용도로 활용될 수 있을 것으로 기대된다.

안전한 도로주행을 위하여 설치된 도로시설물들은 주야간에도 식별할 수 있도록 제작되었으나, 기상악화 시 제 기능을 발휘하지 못하고 있다. 최근에는 원거리에서도 명확하게 인식할 수 있는 전기전자기술로 제작하고 있으나, 이들은 고장이 빈번하여 수시로 교체해야 하므로 교통정온화와 유지관리에 많은 문제점들이 나타나고 있다. 본 연구는 이러한 문제를 해결하기 위하여 교통사고가 빈번한 지역에 반영구적으로 이용할 수 있는 LED 표시등을 설치하고, 이를 시스템과 연계하여 유지 관리할 수 있는 모니터링시스템을 개발하였다. 이를 위하여 시스템은 윈도우 운영체계 기반으로 하였고, 무선통신망과 연결하여 P.C에서 운용될 수 있도록 개발하였다. 그 결과 현장에 설치된 LED 표시등의 배터리 상태정보를 실시간으로 분석을 할 수 있었고, 그 수명주기를 예측함으로서 효율적으로 관리할 수 있었다.
