This study takes cultural space facilities as the research object, trying to grasp the status quo of universal design. By selecting Busan Museum, Busan Museum of Art, and Busan Museum of Modern Art, masters the applicability and characteristics of universal design, and gets the improvements. First, through literature review, the concepts of universal design and evaluation elements are considered. Secondly, obtains five evaluation elements by analyzing previous research. Thirdly, a field survey of various cultural spaces were conducted. gains the relevant status and problems of universal design. According to the results of the detailed evaluation project of cultural space also shuowed that the Busan Museum of Modern Art, Busan Museum, and Busan Museum of Modern Art followed in order, while the average applicability of the universal design of the three cultural spaces accounts for 53.6%. In addition, the results of the average evaluation of the facilities show that the additional facilities are the best, in turn internal facilities, sanitation facilities, other facilities, and guidelines facilities. In the future, it is deemed necessary to conduct regular surveys on universal design and renovate related facilities for public cultural facilities.

The increment of impermeable land area due to widespread land development caused the adverse impact on urban disaster prevention because it could decrease the peak rate of runoff as well as increase the runoff and peak flow during rainy period. To date, little research has been conducted on the infiltration characteristics and quantitative analysis because of their highly dependence on construction method, paving material, surface permeability, and field condition. Hence, this study was performed to investigate the infiltration characteristics of runoff-reducing facilities according to the type of paving material, which were examined using experimental apparatus with varying paving material and rainfall intensity, and thus to provide fundamental research data for runoff-reducing infiltration facilities. In this study, the infiltration characteristics were examined under the rainfall intensity of 20, 30, 50, 80, 100, 200 mm/hr for a variety type of paving materials such as concrete, asphalt, sand, grassland, and permeable paving material. The infiltration rate for permeable paving material was observed to be more than 93% under the condition of less than 200 mm/hr of rainfall intensity. For the compacted earth and grassland, the ultimate infiltration rate was estimated to be about 13% to 67%. The permeable paving material was concluded to be the most appropriate one for the runoff-reducing infiltration facilities because it has more favorable advantages than others in the light of infiltration volume, disaster prevention, and river training.

정부는 자전거 이용활성화에 관한 법률」을 1995년에 제정하여 지자체별 자전거이용시설의 정비계획을 수립하도록 하였지만 실제적으로 수립되고 있는 많은 정비계획들이 아직 초기단계기고, 사전에 충분한 시간을 갖고 세밀한 분석과 연구 없이 수립되다보니 상위계획과의 연계성부족과 지역적 특성에 부합되는 계획안 부족, 도로설계기술의 부족 등 많은 부분에서 문제점들이 지적되고 있다. 따라서 보다 발전한 연구내용의 계획으로 실제적으로 자전거 활성화에 기인하기 위해서 도출되는 문제점들을 진단하고 수정 분석하여 보완하는 작업이 필요하다. 본 연구에서는 1995년부터 1998년 상반기까지 내무부에서 검토된 자전거이용시설 정비계획 보고서 중 10개 도시에 대하여 각도시별 정비계획의 문제점을 현황조사부분과 분석부분 계획부분으로 분류하여 분석하고 이의 개선방향을 제시하였다.

국가기반시설 제어시스템은 독립망 운영 정책 적용과 독자적 제어시스템 통신 프로토콜 사용으로 안전하다고 여겨져 왔다. 하지만 최근 국가기반시설 제어시스템을 대상으로 한 최초의 사이버 무기인 스턱스넷(Stuxnet) 악성코드의 발견 이래로 현재까지도 지속적인 사이버 위협 및 사고사례가 보고되고 있다. 이에 따라 사회경제적으로 큰 혼란을 야기할 수 있는 제어시스템 대상 사이버공격에 대응하기 위해 일반 IT 환경과는 다른 제어시스템만의 특성이 반영된 보안기술이 요구되고 있다. 본 논문에서는 제어시스템 보안기술 중 침입탐지 시스템 기술 연구 동향을 분석하고 해당 기술이 적용되는 제어시스템 영역과 제어시스템 통신 프로토콜별 특성에 따른 기술들의 특징을 분석한다. 또한, 탐지 기법에 따른 제어시스템 공격 탐지 성능을 비교 및 분석한다.

현재 우리나라는 1980년대 후반부터 도시폐기물 소각시설을 설치하기 시작하여 전국적으로 20 여곳의 대형 소각장이 가동되고 있으며 대기오염 방지 기술도 발전에 발전을 거듭하여 불과 10 여년 동안에 선진국 수준의 대기오염 배출기준을 만족하는데 아무 문제가 없을 정도로 되었다. 그러나 소각후 발생 하는 소각재의 경우 비산재는 고형화등의 처리 후 매립하고 바닥재는 별도 처리없이 매립하는 실정이어서 매립 후 시간이 흐를수록 매립된 소각재에서 용출되는 다이옥신과 소각재 중에 포함된 중금속 등에 의한 토양오염과 수질오염의 우려가 남아 있는 것이 사실이다. 소각후 남는 소각재는 폐기물량의 약 15 %, 비산재는 약 1.5 % 정도 발생하는 것으로 볼 때 매립은, 특히 다음 세대에 유산으로 남겨진다는 점에서 더 이상 적절하지 않은 해결책으로 생각되며 유럽과 일본 등 선진국에서는 이미 이와 같은 소각재에 대한 무해화 처리기술이 개발되고 속속 상용화되고 있으므로 우리나라도 하루빨리 열분해용융시설등 신기술을 개발하거나 도입하여 세계적 환경 기술경쟁 에서 선진국과 어깨를 나란히 함은 물론 청정한 국토를 후손에게 물려줄 수 있도록 하는 대책이 강구되어 야 할 것이다. 본 고에서는 폐기물 처리기술의 세계 적 동향을 살펴보고 폐기물의 완전 자원화에 성공한 대우 써모셀렉트 열분해용융 기술의 특성에 대해 소개하고자 한다.

Recently, serious parking problems are occurring due to the difficulty of securing sufficient parking space, and it may lead to other traffic or social problems. In order to solve the parking problem in areas and districts beyond a certain range, a study on-roads and off-street parking lots reflecting regional characteristics is necessary. Therefore, this study establishing a parking demand calculation model for use as a basic study in establishing on-road and off-road characteristics. In order to conduct the study, Dong-fu, Daegu Metropolitan City was divided into dongs, and parking facilities and parking demand were investigated. The survey time was divided into daytime and nighttime on weekdays, and the types of vehicles were divided into three types: passenger car, small trucks and buses, large trucks and buses. As explanatory variables for calculating parking demand, the total floor area of buildings for each of six purposes was used, including detached houses, apartment houses, neighborhood living facilities, cultural and assembly facilities, business facilities, and sales facilities. As a result of the correlation analysis, among the six explanatory variables, the total area of neighborhood living facilities showed a significant correlation with on- and off-street parking demand. A regression analysis model was constructed using the total area of neighborhood living facilities as an explanatory variable, and statistically significant results were obtained.

The different compliance concentration of effluent limit is applied to effluent discharged from public sewage treatment works(PSTWs) in each watershed on the basis of water quality thereof in accordance with the enforced Watershed Sewer System Maintenance Plan in 2013. It is necessary to set the compliance concentration of effluent limit for PSTWs in watershed sewer system, in order to achieve water quality criteria for regional watersheds or target water quality under TMDL program. Watershed Environmental Agencies establish the Watershed Sewer System Maintenance Plan and set the compliance concentration of effluent limit for PSTWs under the plan. The agencies have a plan to apply strengthened effluent BOD concentration limits for PSTWs in I to IV area grade, respectively. Effluent BOD concentration limits will be strengthened from 5~10 mg/L to 3 mg/L in II~III area grade, from 10 mg/L to 5 mg/L in IV area grade. Uniform application of effluent BOD concentration limits to PSTWs in the watershed sewer system need to be complemented considering type of sewage treatment technology employed and watershed characteristics. Therefore, this study presents assessment methodology which analyze for the compliance concentration of effluent limit to affect water quality of discharge watershed using simulation model for the Jinwee-stream watershed.

The purpose of this study is to develop effective destination management strategies for three typical tourist destinations in Kangwon province based on the importance-performance analysis. The results show that overall performance levels of 21 management attributes in three destinations is relatively low, compared to the importance levels of the attributes. 6 attributes place in Concentrate Here, 4 attributes in Possible Overkill, 6 attributes in Keep Up Good Work, and 5 attributes in Low Priority. There is no significant difference in the importance level among three destinations, while performance levels are the lowest at Naksan & Kyungpo beaches, and highest at Ganhyun area. Findings of the survey expect to be used as fundamentals in management policy making process for each destinations.

Since the establishment of a large-scale public experience facility in Korea, the construction project of public experience facilities has recently changed to a form where local governments or local education offices place delivery alone or agreements. In particular, due to the low frequency of delivery and the nature of delivery organization that do not have specialized organizations specializing in Delivery Framework, the role of enhanced Public Owner is needed. In response, this study investigated the current status and operation status of public experience facility construction projects in Korea and derived problems and directions for improvement of the current role of Public Owner. In addition, the study proposed the improvement of the role of public Owner in public experience facilities, which are composed of the promotion stage and functions reflecting the factors and attribute information of the business characteristics.
