  • The reliable operation of onsite emergency diesel generator(EDG) should be ensured by a conditioning monitoring system designed to maintain, monitor and forecast the reliability level of diesel generator. The purpose of this paper is to develop condition diagnosis algorithm(logic) and analysis program of engine for the accurate diagnosis in actual condition of emergency diesel generator engine. As a result of this study, we confirmed that developed engine condition diagnosis algorithm and analysis program could be efficiently applied for actual EDG engine in nuclear power plant.

  • 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.

  • The purpose of this research therefore, was to conduct research on the actual state of manufacturers of cycle wears and the condition in wearing; to present the basic data to develop cycle wears which can lessen the trouble for the human body and an excellent feeling in wearing. For research on the actual state of manufacturers of cycle wears, three domestic companies were grasped. To inquire the condition in wearing, the method of questionnaire was used for 100 peoples consisted of male cycling professional players and ordinary peoples with the same tastes. As the result of research: The manufacturers were targeting for the professional players and men with the same tastes. They produced goods by themselves as well as in the form of subcontract, and they did not classify goods for male & female. Materials they used for cycle wears were mainly composed of jersey with spandex and nylon. The production ratio of cycle wears is shown as 80% for company A, 25% for company B, and 90% for company C. They make a pattern of cycle wears by a technical tie-up with foreign companies, or by the development of their own pattern. As the result of study on the present condition in wearing cycle wears according to each season, it was figured out that the users usually weard short-sleeved T-shirts with dividing zipper for summer upper garment, shorts most preferably for summer lower garment; long-sleeved shirts for spring and fall upper garment, and shorts with incision most preferably for spring and fall lower garment. Also, they usually weard jumpers with incision for winter upper garment, and long pants in which ankle parts of incision were tightened most preferably for winter lower garment.

  • The purpose of this study is to conduce the survey of three groups of college women living in different residential districts, Seoul, Gyeonggi-do and a district, each other, analyze the actual condition of wearing blue jeans, comparative investigate actual condition in each residential district of wearing blue jeans and cognition by change of crotch length and trend through comparison of cognition on dressed blue jeans with short crotch length. By which investigation, it was intended to understand their condition and propose of blue jeans as may offer fit with short crotch length. As the result of this study, it presented college women had hipbone blue jeans in order of $2\sim3$ and more than 4 in all of residential districts, they purchased hipbone blue jeans with crotch length in order of for middle crotch(23 cm) and short crotch(21cm) commonly in all of residential districts, and they care a lot for exposing back waist and hip of hipbone blue jeans without reference to residential district. They had a bad feeling for exposure, and as an alternative to deal with this, they answered mostly on 'wearing hipbone underwear' or 'wearing long upper garment', and there was significant difference between residential districts in silhouette and exterior fitness of crotch length among important factors when wearing hipbone blue jeans.

  • The needs of integrated play and space for both healthy children and children with Disabilities is increasing due to positive effect of integrated play. However, existing plan of play space have not considered children with Disabilities as the user and Integrated Perspective what children and children with Disabilities can do together is insufficient. For these reasons, establishing guideline of the Barrier Free Play Space and Model Development is required to meet the New Paradigm's demands. The purpose of this research is to deduce present condition and problem of play space through the Actual Condition Analysis of domestic Play Space. This study have given careful consideration to the actual condition of play space for 3 types by Types of Installation method. As a result, there are many problems from research point of view and facilities for the disablilities too. Consequently, element of plan and facilities for the disabled which are problems should be shown the direction focused improvement, moreover major task is build a barrier free play space as a place of social integration.

  • The purpose of this study is to understand the actual condition of Bogumjari Housing Complex residents' management consciousness and to provide suggestions on ways to induce residents' volunteer participation and practice of the apartment management. This study was performed on Bogumjari Housing Complex which was occupied in 2012 and the similar-sized apartment complex of the private condominium to compare and analyze their actual condition of management and consciousness of their residents. The results of the analysis could be summarized as follows: 1) In terms of management of operation, there is no distinct difference. In terms of maintenance management, Bogumjari Housing Complex has difficulty in maintenance because of lack of management manpower. Also, the apartment complex of the private condominium has higher spontaneous participation rate, which seems to be influenced by activation of various organizations. 2) In terms of the satisfaction of management process, Bogumjari Housing Complex has have higher satisfaction with promotion of the apartment Management Rules, but it has lower satisfaction with public hygiene, community facility maintenance and operation of program than that of apartment complex of the private condominium. 3) Bogumjari Housing Complex has higher maintenance and participation consciousness, drawing conclusion that Bogumjari Housing Complexs' residents have higher expectations for apartment, a keen interest and strong will.

  • Recent developments in Bridge Management Systems (BMS) and in Life-Cycle Cost (LCC) of bridges, have raised the need for evaluation procedure of future condition (Deterioration) of a bridge. Predicting future deterioration is not an easy task due to limited past data to extrapolate from and also due to difficulty in measuring actual deterioration such as section loss of steel on an actual steel bridge. Also, increase in live load and reduction of resistance are random variables, thus a probabilistic approach should be adopted for determining the future deterioration. Due to difficulties in evaluation of future deterioration on steel bridges, accepting uncertainties within a reasonable error, a deterministic procedure using bridge condition rating can be a useful tool for projection of future condition of bridges to identify repair and maintenance needs. The object of this paper is to determine applicability of evaluating deterioration of steel bridge components based on Bridge condition ratings. Bridge condition ratings of bridge components show wide variation for bridges of same age and does not directly correlate well with the age of the bridge and/or deterioration of the bridge. High uncertainty can be reduced by breaking down the rating and by sensitivity analysis. From refined condition rating data, generalized deterioration profile of structures based on age can be derived. Examples are shown for sample bridges in USA. Approximately, 3,000 short to medium span steel bridges were listed in the inventory database. Results show wide variation of rating factors but by subdividing the Bridge condition ratings for various categories general deterioration profiles of steel bridges can be determined.
