In recent years, We have had many civil application about electromagnetic waves according to increasing of construction of electric power facilities. This paper describes human body effect by regulation management and the guidelines of human body protection of electromagnetic waves. We try to evaluate the effect of electromagnetic waves by actual measurement at wind power generation complexes in Hang-won, Jeju.

The actual behavior of joint is traditionally disregarded in steel frame design. In fact, the structural analysis of steel frames is generally carried out by assuming that joints fulfil the ideal condition of either a hinge or a fixed-end restraints. In this way, calculations are made somewhat simpler, but the structural model is not able to reflect the actual structural response. Therefore, steel frame classification system for estimation or analysis about behavior of steel frame should be established, and range that each connections belongs should be divided definitely. This research presents realistic and practical moment-rotation relation through investigation and analysis of steel frame beam-to-column classification system.

There are about 38,977 CNG cars and 247 natural gas vehicle charging stations in operation in order to improve the urban air environment. With the introduction of natural gas vehicles, the atmospheric environment, which was the main cause of air pollution in the metropolitan area, was remarkably improved. However, unlike these positive effects, CNG bus accidents, which occurred more than 10 times since 2005, have caused concern among the majority of citizens using public transportation. It is necessary to make a judgment on the feasibility and future direction of CNG pressure vessel safety management that can safeguard the safety of CNG pressure vessel at the time of starting. In this study, we investigates production and use of CNG vessel, the current status of safety management of CNG bus transportation companies & charging stations and then proposes measures to prevent accident recurrence and safety management based on the actual situation investigation and analysis.

The purpose of this study is to clarify the actual condition of the daily living activities of the elderly with dementia in skilled nursing facilities. The thorough investigation and observation works were made from the view points of daily living behaviors and behavioral places of the recuperating elderly with dementia in skilled nursing facilities. This article discusses about the basic characteristics of the elderly and the actual condition of the daily living activities of the elderly with dementia in 3 skilled nursing facilities. The results of this study are summarized as follows; There is no wide difference between skilled nursing facilities on the characteristic of living behaviors of the elderly with dementia. Daily living activities and the use of spaces are largely influenced by the daily program and the operation policy of each skilled nursing facilities in addition to human relationship of the elderly with dementia. Common spaces such as day room, dining room plays an important role for their daily living activities, because that most of the elderly with dementia stay long during daytime. Layout of each private room and common space seems very crucial point in designing these facilities, in order to enable demented people to live their lives more independently.

The purpose of this study was to investigate the actual conditions of management of the healthy family field practicum and to present suggestions for its improvement. For this purpose, a preliminary investigation, survey, data analysis, interview as secondary source, and final data analysis were processed as research methods. The subjects of this study were the 42 supervisors in the centers which oversee the field practicum experience and the 12 supervisors in the centers which do not oversee the field practicum experience. 3 supervisors were interviewed to inquire about the reformation of field instruction in Healthy Family Support Centers. Analysis was made of the general characteristics of the above-mentioned 54 supervisors, including sex, age, academic background, certificate of qualification, class of position, and length of career related to the healthy family program. The environment of the field practice, such as the numbers of students supervised, time of field practice, practice hours, and so on, was examined in the centers which oversee the field practicum experience. The actual condition of operation investigated was divided into the preparatory stage, the early stage, the midterm stage, and the end stage. Research was conducted on the improvement of the field practicum, including the proper number of students supervised, adequate practice hours, interaction with universities or colleges, obstacles to the field practicum, and of practicum. The possibility and preparation of a further field practicum was conducted for 12 Healthy Family Support Centers, by inquiring about (a) the reasons for not overseeing the field practicum experience and (b) the needs of universities or colleges for a field practicum. The 54 supervisors surveyed suggested a particular need for improvement in human resources, the space of field instruction, system of field practicum, length of practice hours, orientation for students etc. This study investigated the actual conditions and suggested improvements of the field practicum in Healthy Family Support Centers. Therefore, its results should be meaningfully used to develop the Field Practicum for the Healthy Family and to conduct further studies.

This paper presents the results of an experimental investigation on a vibration-based damage identification framework for a steel girder type and a truss bridge based on acceleration responses to operational loading. The method relies on sensor clustering-based time-series analysis of the operational acceleration response of the bridge to the passage of a moving vehicle. The results are presented in terms of Damage Features from each sensor, which are obtained by comparing the actual acceleration response from the sensors to the predicted response from the time-series model. The damage in the bridge is detected by observing the change in damage features of the bridge as structural changes occur in the bridge. The relative severity of the damage can also be quantitatively assessed by observing the magnitude of the changes in the damage features. The experimental results show the potential usefulness of the proposed method for future applications on condition assessment of real-life bridge infrastructures.

The purpose of this study was to present the effective activation of apparel CAD system and for this, the investigation of actual condition of CAD using companies and comparative inspection with the advanced study were carefully considered. The results were as follows : 1. The investigation result of the system using enterprises is that the direct effect from the operation of the CAD system after its introduction was the promptness, ad the indirect effect of it was the growth of operation level and operating reliance. 2. The problem originated from the system was the uncertainty of employer effectiveness and the financing source for it when introduced, and the lack of consciousness of it when operated. 3. The using level in pattern manufacturing function was lower than that in grading and marking. Therefore, as the full automation in CAD system is a part of CIM construction and the direction to which apparel companies should go, a firmly connected system between management & the persons in charge in apparel companies, facility supplying companies, universities & other educational institutes, and the Government should be duly constructed first of all n order to achieve this aim.

The disabled peoples increase in number by disasters from the industrialization and urbanization. The physically handicapped people experience many difficulties in using the facilities in the public buildings. So, this survey proposed the necessary conditions for the handicapped peoples to use without any trouble in public buildings. The objects of investigation were public buildings, village offices, a public library, synthesis hospitals banks, an express bus station, a wedding building, a railroad station etc.. Conclusions were as follow \circled1 The most of buildings were established access road in regulations but parking area was established inappropriately in regulations \circled2 The most of convenience facilities were concentrated on first floor but were established barely in more than second floor. \circled3 The most of convenient facilities were established in appropriately in regulations. \circled4 The other convenient facilities(reception desk, ticket agency, work desk etc.) were not established nearly in the buildings of investigation.
