본 연구는 건설방수분야의 유효자원 재활용 현황에 대하여 시장 특성 상 정확한 파악이 어려운 점을 고려하여 이에 대한 대안으로 관련 제도 및 인증을 중심으로 조사하여 분석하는 방식으로 연구를 진행하였다. 조사 대상은 건설방수분야에서 획득 가능한 유효자원 재활용 관련 인증으로 선정하였으며, 환경표지, 녹색기술, 신기술을 중심으로 현황을 파악하고 분석하였다. 현황 파악 및 분석 결과, 환경표지의 경우 총 38개 제품이 유효자원 재활용을 사유로 인증을 획득하였으며, 녹색인증은 총 10개, 신기술의 경우, 8개 기술이 유효자원 재활용을 응용한 기술로 확인되었다. 재활용된 자원은 대부분 합성고분자계(EVA, PVC 등), 폐타이어 분말, 폐고무 등이 주를 이루고 있음에 따라 건설방수분야에서의 유효자원 재활용은 전반적으로 소재의 다양성에 있어 제한적인 것으로 확인되었다. This paper intends to analyze the roles of regulations and certifications within the construction market that affect the effective recycling and application methods of construction waterproofing industries. Certifications, eco-labels, green certification patents, and new excellent technologies obtained in construction waterproofing industries are studied. In accordance to the study results, it was determined that, a total of 38 items obtained eco-labels with effective recycling as the theme, 10 items with green certifications, and 8 items with New Excellent Technologies. Regarding the types of effective recycled resources, most of them were concerned with composite-polymer(EVA, PVC, etc.) materials, waste tire powder, waste rubber, etc., which indicated that there is a clear limitation in the variety of the materials that are eligible for effective recycling in the construction waterproofing industries.

본 연구는 시트-도막 복합방수공법에서의 고질적인 접합부 파단 하자를 해결하기 위한 목적으로 고안한 접합부 2면 접착을 통한 분리거동 유도 기술의 적용에 있어 기술의 유효성 및 성능검증을 목적으로 진행하였다. 이를 위해 비교 시험군으로서 3면 접착 기술이 적용된 I형 접합부를 선정 및 제작하여 연구 대상 기술과 인장성능 및 신장률 평가를 진행하였다. 평가 결과, 3면 접착방식의 비교 시험군 접합부의 인장강도의 경우 14.2N/mm 신장률 335%로 확인되었고, 본 연구 대상인 분리 거동형 접합부의 경우 인장강도는 13.8N/mm 신장률 587%로 확인되었다. 이러한 결과는 3면 접착방식의 경우, 모든 재료가 구속되어있는 형태로 구성되어 있음에 따라 강도적 측면에서 본 연구 대상에 비해 높은 결과가 나온 것으로 판단하였다. 또한 본 연구대상인 분리 거동형 접합부의 경우, 인장응력 및 변위가 발생하였을 때 무절점 인장응력(Zero-span tension)이 발생하지 않음에 따라 하부 시트층과 상부 도막층이 동시에 파단되지 않고, 하부 시트층과 상부 도막층이 분리거동 신축부재에 의해 분리되면서 하부 시트층 부터 순차적으로 1차 파단되고, 변위 허용 구간에 들어서면서 상부 도막층이 본연의 신축성을 나타내며, 지속적인 변위를 나타내다가 일정 변위 구간에서 2차적으로 파단되는 특성을 나타내는 것을 확인할 수 있었다. This study focuses evaluating the efficiency and performance evaluation of composite type sheet-membrane waterproofing method that utilizes a separation behavior inducement system designed to resolve the chronic problems of disintegration and damage of overlap areas of waterproofing layers. As the result of the test, the tensile strength value was at 13.8N/mm and elongation rate at 587% for the separation behavior inducement type specimen, and the compared specimens had 14.2N/mm for tensile strength and 335% for elongation rate. For the separation behavior adhesion method specimen, when tensile stress or displacement occurred, the Zero-Span tension occurrence did not follow, which resulted in that the bottom sheet layer and the top membrane layer did not simultaneously becoming damaged. When undergoing the top and bottom layers were separated through separation behavior due to lack of flexibility, the bottom layer began to damage at the primary stage, and with the allowed boundary the upper membrane layer began to display flexibility and showed continuous displaced resulting in secondary phase damaging.

본 연구에서는 아스팔트 매스틱 도막방수재를 구성하는 원료의 종류 및 함량을 조정하여 누유발생 특성을 분석함으로써 원료와 누유발생 간 특정 상관관계를 정량적으로 파악하는 것을 목적으로 하였다. 이를 위해 아스팔트 매스틱 도막방수재의 유·무기계 체질안료인 CA(탄산칼슘)와 ASE(침강방지제) 두 개 원료를 선정하였으며, 입도 및 함량을 변수로 설정하여 배합을 통해 샘플시료를 조성하고 샘플시료별점도 및 누유안정성(20℃, 40℃) 평가를 진행하였다. 평가결과, 누유안정성 및 점도는 CA 평균입도에 반비례하며, ASE 함량에 비례하는 상관관계가 성립하는 것을 정량적으로 증명하였다. 본 연구결과는 향후 아스팔트 매스틱 도막방수재의 누유 개선을 위한 배합 연구 시 기초 배합설계의 핵심적인 근거자료로서 활용이 가능할 것으로 판단된다. In this study, the purpose of this study was to quantitatively grasp the specific correlation between the raw material and the occurrence of leakage by analyzing the characteristics of leakage by adjusting the type and content of the raw material constituting the asphalt mastic coating waterproofing material. To this end, two raw materials, CA (calcium carbonate) and ASE (anti-sedimentation), which are organic and mineral extender for asphalt mastic waterproofing membrane coating, were selected. viscosity and oil leakage stability (20 ℃, 40 ℃) was evaluated. As a result of the evaluation, the oil leakage stability and viscosity were inversely proportional to the CA average particle size, and it was quantitatively proven that a correlation in proportion to the ASE content was established. The results of this study are expected to be used as core data for basic mixing design in the future mixing studies to improve leakage of asphalt mastic waterproofing membrane coating.

In Korea, the extensional expansion of historic cities has resulted in the doughnut pattern. Due to that, people began to have interest in urban regeneration in terms of their attention to declined cities as well as efficient land use. Also, to solve problems related to aging society or population decrease we are facing now, there are various efforts being made. The purpose of this study is to recognize the aged as regional resources for urban regeneration and find out ways to regenerate cities through the aged. As a way of it, this author intends to find out ways to regenerate regions by vitalizing senior houses in declined cities. This researcher sets up a model for urban regeneration realized by vitalizing senior houses and utilizes Fuzzy-AHP analysis to suggest ways for urban regeneration realized by vitalizing senior houses based on the results drawn. First, it is needed to support house remodeling projects preferentially. Second, it is necessary to use house mortgage. Third, it is required to maintain environment for walk safety so that the aged can move safely. Fourth, it is needed to establish a senior welfare service system such as medicine and education in the aspects of residential welfare. Lastly, it is necessary to induce maintenance technique for small-scale block-unit residential regeneration and cultivate housing cooperatives for it.

Objective: This study explored the optimal level of color and light level for crime prevention environment design (CPTED) focusing on pedestrian emotions in night environment. Background: As a solution to reduce the crime that occupies the highest proportion of various social unrest factors, the crime prevention environment design (CPTED) technique is being used. Method: Color (21 levels) and light (3 levels) were selected as efficient design factors to reduce the fear of crime. Five pairs of emotional words related to "fear of crime" were derived. We provided the nighttime alley environment composed of various combinations of color and light using the simulator. The participants answered the questionnaire composed of 7 points of Likert scale. Results: There was a difference in fear of crime according to color in all emotional lexical pairs. Also, in all emotional lexical pairs except one pair, female showed higher fear of crime than male. Conclusion: This study suggested the optimal combination of color and light in alley environment. Color (19), (20), and (21) showed low fear of crime in all light levels. Color (17) showed low fear of crime in Light (Blue). And color (18) showed low fear of crime in Light (Blue) and Light (Orange). In particular, color (8), (11), and (16) did not show low fear of crime, but they showed low fear of crime when it matched light (Blue). Application: From the point of view of integrating color and light in crime prevention environment design, the combination of color and light proposed in this study is highly recommended.
