Facilities with high risk of a disaster or requiring continuous safety management are designated as class-III facility. In order to designate a class-III facility, it is evaluated based on the safety status of the facility, the risk to the building users, and the number of years elapsed of the facility, etc. and this shall be referred to the actual condition survey for the designation of a class-III facility. In the actual condition survey conducted to designate the safety status is calculated by the checklist based on the evaluation scores consisting of five stages each item, and is evaluated in three stages by 'good', 'careful observation', and 'designated review' through the average of the combined scores. Currently, the actual condition survey being conducted applies only structural stability, and the risk factors such as damage to the finish, the risk of cracking, and the type and weight of major structures are not included in the checklist for the actual condition survey, so even if experts think it is dangerous, scores cannot be reflected. Therefore, this study aims to analyze the problems of checklist of the actual condition survey for the designation of class-III facility and to propose an improvement plan for the checklist for the actual condition survey.

Recently, although researching and developing of safety and maintenance on domestic infrastructure facilities in KOREA are important, there has been very little research regarding on a comprehensive and integrated survey of actual condition. Therefore this study asserts the necessity of the survey process of actual condition by period planning(short-term, middle-term, long-term). The purpose of this study is to investigate current situation and to suggest the whole process method, and to establish survey process of actual condition on domestic infrastructure facilities.

The rebar work is very related to the safety and durability of the building. Recently, the rebar work is produced some serious problems due to the lack of skillful crafts-man and the rising cost of rebar materials. Many papers have dealt with the rebar work of the manufacturing system in plants with a view to improvement those problems. But, the research on the rebar work of the manufacturing system in field is in a insignificant condition. This study presents the following improvement schemes as a result. First, the education strengthening for evaluation on practical affairs, second, the reinforcement of drawing & management in shop drawing and finally the simplification of apartment rebar work in slab. Also, this paper aims at advancing apartment rebar work by the actual condition survey in slab work. The further research will be needed about the whole structure parts such as foundation, wall, girder and rebar truss-deck plate as one of the improvement methods.

본 연구에서는 UAV를 이용한 국공유지 실태조사 필지의 효율성과 정확성을 평가하기 위해 지적현황측량 검사점의 정확성과 경제적 비용측면에서 제시하였다. 분석결과를 요약하면 다음과 같다. 첫째, 정사영상의 위치오차는 평균적으로 X오차 0.033m, Y오차 0.023m로 나타나 평면거리 연결교차로 계산하면 RMSE 평균은 0.046m로 나타났다. 둘째, 정사영상과 VRS-GNSS 성과비교에서는 UAV 정사영상 이미지 검사점의 최대 RMSE는 0.076m이고 최소 RMSE는 0.042m로 나타났다. 세째, 모든 검사점이 현행 지적측량규정에 명시된 1/1,200의 축척에 해당하는 0.360m 이내의 오차범위를 만족하였다. 끝으로 국공유지 실태조사를 위한 경제성 평가에서는, UAV 활용방법이 지적현황측량 방법보다 26,497,436원이 더 적게 들어가는 것으로 나타났다. 따라서, 본 연구결과 국공유지 실태조사에서 UAV를 활용하는 방법은 정확도 측면에서도 법적 기준을 충족하며, 경제성 측면 역시 지자체의 예산을 더욱 줄일 수 있는 방법으로 나타났다.

고령화 사회에서 고령사회로 급격하게 변화하는 시점에서 노인의 특성과 생활실태를 정확히 파악하여 사회전반에서 발생하는 변화의 양상을 인식하고, 이에 대하여 효과적이고도 적극적으로 대응해야 할 필요성이 있다. 본 연구에서는 2008년도에 전국적으로 조사된 노인생활실태 및 복지욕구조사자료를 바탕으로 가구와 개인정보에 대한 노인생활실태를 파악하고 이러한 변수가 생활 만족도에 미치는 영향에 대하여 통계자료분석을 실시하여, 현실적 타당성과 적합성을 지닌 고령사회의 사회정책수립에 도움이 되고자 한다.

The primary objectives of this research are to survey actual condition and propose the improved standard size for office chairs. In order to accomplish this objectives, questionnaire method was used. The subjects for investigation are 271 office sedentary workers from 19 office workplaces. The survey of a actual condition showed that the office chairs included many contr- oversial points which cause occupational health problems. The main causes of office sedentary worker's health problems are insufficient adjustabilities and inappropriate design specifications. Expecially, insufficient adjustabilities led harmful sitting postures. To improve the existing Korean standard size for office chairs, anthropometric procedure was developed. In this approach, six design factors were determined, that is, seat pan height, seat pan width, seat pan depth, seat pan inclination, armrest height and width. The study found that improved Korean staneard size was strikingly different from existing standard.

The concrete structures are hardly ever built under ideal conditions. So many defects may occur for a various reasons such as unsuitable and defective materials, construction methods, poor workmanship, particular structural form and prevailing weather conditions. Some structural form can greatly increase the risk of occurrence of defects. Therefore we investigated the actual condition of the deterioration factors for reinforced concrete apartment, which was composed of 85 apartments with various building ages in different regions with five evaluation the deterioration factors of apartment building to establish the overall evaluation system of deterioration degree for reinforced concrete apartment in Korea.
