According to the statistics of occupational accidents in 2009, the scaffolds and work platforms were main objects causing fall accidents in construction sites. But many workers install and use the work platforms on the mobile scaffolding without considering about safety standards. We had conducted a nationwide survey about how workers obey safety standards for the work platforms of the mobile scaffolding. As the result of a survey, no one follow a gap standard between materials of work platforms and installation of toe board. And it is a low proportion that comply with the install of safety guard rails and the use of stoppers. This is lack of consciousness for the safety certification and regulations. For safe use a mobile scaffolding, It is needed to educate a manager on the safety standards and to develop a product to install and dismantle easily.

Due to the increasing needs of anti-fall device for elderly, it is required to develop the test rigs for fall simulation. The femoral bone model consists of silicone and steel is used as an effective device to simulate falls. In this work, we propose five different femoral bone models and analyse them by using a commercial FEA tool. It has been shown that two kinds of simplified models exhibit the simulated side falls with an error range of ~1% in the impact load of femoral neck compared with full model. Especially, the upper tissue model is found to provide us with the best efficient test environment, attributable to its simple structure.

Slipping during various kinds of movement often leads to potentially dangerous incidents of falling. The purpose of this paper was to review some of the research performed in the field including such topics as rating scales for balance, kinematics and kinetics of slipping, adaptation to slippery conditions, postural and balance control, and protective movement during falling. Controlling slipping and fall injuries requires a multifaceted approach. Environmental conditions (state of floor surface, tidiness, lighting, etc), work task (walking, carrying, pushing, lifting, etc), and human behavior (anticipation of hazards, adaptation to risks, risk taking, etc) must be accounted for in the assessment of slip and fall-related risks. Future directions of research must deal with modeling of basic tribophysical, biomechanical, and postural control process involved in slipping and falling.

A method to calculate the magnetic moments for $d^1$ and $d^2$ complexes in a strong crystal field of trigonal symmetry has been developed in this work choosing the trigonal axis (Ⅲ) as the quantization axis. The calculated magnetic moments using this method for $d^1$ and $d^2$ complexes in a strong trigonal ligand field fall in the range of the experimental values. The dipolar shifts for $d^1$ and $d^2$ complexes in a strong trigonal ligand field are also calculated using the calculated magnetic susceptibility components. The calculated values of the dipolar shifts also fall in the reasonable range.

This study review about smart work to appear the use of smart device, and find the management plan for activating of smart work. Our national's smart work that is the best internet environment in worldwide fall behind foreign country. This study offers for the activating strategies of smart work. Fist, it is to change perception about smart work. Second, it should be clear up legal definition and category of smart-work. Third, it is that tighten up security of smart equipment. It is hard to achieve effects, as long as we get used to face-to-face work processing. Based on accurate perception about smart work on both employees and manager, this study suggest that it is important to change perception and to make actively use of smart work.

Due to urban regeneration projects or changes in the living environment, there is an increasing need to demolish old buildings that have lost their functions. Demolition of above ground and underground structures is an important construction project that greatly affects the construction period and safety of the entire process. However, it is difficult for the safety officer to manage the demolition work due to the lack of specific and diverse data applicable to the site of the demolition plan. Therefore, in this study, items that need to be improved in structural safety when the above-ground and underground structures are demolished are reviewed and organized. For the main contents of structural safety management in demolition work, 1) structural review reflecting the order of demolition work, 2) installation and dismantling of steel pipe scaffolding and dust nets, 3) installation and dismantling of system scaffolding, 4) installation and dismantling of fall prevention nets, 5) jack support Installation and dismantling, 6) movement of equipment, movement and planning between floors, 7) equipment for demolition of structures, height of remnants, 8) site cleanup, and 9) equipment operators were categorized and arranged.

This study examine operating system for eco-friendly container terminal and shows the usefulness of the Importance-performance analysis grid in evaluating container terminal operating technology. Importance-performance analysis enables management to evaluate and identify the major strengths and weaknesses of eco-friendly container terminal operating technology's key success factors. This study identified a list of 20 items from the eco-friendly container terminal literature reviews, and each item was rated using a 5-point Likert scale. Responses were obtained from 250 questionnaires. The importance-performance grid shows that 13 items fall into the "Keep up the good work" quadrant, 2 items fall into the "Concentrate here" quadrant, 2 items fall into the "Low priority" quadrant, and 3 items fall into the "Possible overkill" quadrant. The findings suggest that an eco-friendly container terminal operating technology is necessary to enhance eco-friendly operating system. The results are useful in identifying areas for strategic focus to help container terminal managers develop eco-friendly container terminal operating technology strategies.

This research has been conducted in order to compare and analyze the role-conflict, job stress and job satisfaction of nurses according to their current work posts. The subjects of this research were carefully selected 426 nurses from 2 university hospitals. The research tool were a role-conflict measurement index, job stress a tool, and job satisfaction Minnesota Satisfaction Questionnaire. The data have been collected using a structured questionnaire from March to May 2003. The collected data have been analyzed using the SPSS PC 10.0V program. The nurses at Intensive Care Unit (ICU) showed highest level of job stress while the nurses at surgical ward showed the lowest level of job stress (F=8.37, p=.000). There was no significant difference in role-conflict and job satisfaction according to the current work posts. According to the results of this research, there was a difference in stress according to the current work posts, and it turned out that the nurses at ICU had the highest level of stress compared to the nurses at other departments, and it causes a fall in job satisfaction.

본 연구는 1990년대 시행되었던 학교시설 현대화 사업 이전 시기인 1970년대 초와 1980년대 초 학교건축에서의 탈표준화를 모색했던 연구들에 주목하여 이들을 고찰하였다. 이들 연구는 후속 사업으로 연결되지는 못했지만 편복도형의 극복이나 시설프로그램의 변화, 학교 건축계획에서의 도시적 차원의 접근, 학교공간 내에 다양한 공간 적용 등을 제안하고 있어 국내 학교건축이 표준화교사로부터 벗어나는데 선례적인 연구로서의 의미를 갖는다.
