To improve productivity in the architecture, construction and engineering industry, it is critical to understand both current and historic trends in construction productivity. This study analyzes and compares construction productivity trends of South Korea, the U.S., the U.K., and Japan 1995 to 2015 using the following three measures: construction labor productivity, construction duration per floor, and construction duration per 1,000 m2 floor area. As the results, the international competitiveness of each country varied according to which measures were used to analyze them. Among the four countries, the construction labor productivity of the U.S. was the highest, followed by that of South Korea. South Korea also had the second highest productivity growth rate, following that of Japan. On the other hand, when analyzed from the perspective of construction duration, the construction productivity in South Korea appeared relatively lower than those of other countries. There were differences in the location of construction competitiveness of each country analyzed by various measures. Therefore, to accurately diagnose and improve the construction competitiveness in South Korea, strategies based on various measures are need to established simultaneously.

With the increasing importance of environmental issues, the cementitious materials with self-cleaning or photocatalytic properties by introducing TiO₂ materials have been gaining a lot of attention. In this work, the influence of TiO₂ particle size and structure on its photocatalytic effect in cement paste was investigated. The degradation of methylene blue solution was used as the parameter for evaluating the photocatalytic effect of micro-TiO2 (m-TiO₂), nano-TiO2 (n-TiO₂), and TiO₂ nanotube (TNT). Moreover, the effect of these three TiO₂ materials on the cement hydration products was characterized by X-ray diffraction (XRD) and thermgravimetric analysis (TG). According to the results, it can be found that all of the TiO₂ materials promoted the formation of hydration products, especially TNT. On the other hand, the m-TiO₂ exhibited a better photocatalytic effect compared to other materials.

저수지 홍수터는 댐 저수지에 자연스럽게 형성되는 계획홍수위와 상시만수위 사이의 토지를 의미한다. 광범위하게 분포된 홍수터는 경작을 포함한 다양한 형태로 훼손되어 왔다. 훼손된 홍수터를 일거에 복원하는 것은 현실적으로 어려우며, 이에 따라 복원 우선순위를 결정하는 방법이 제시되고 있다. 이 과정에는 다양한 인자가 고려되며, 그 중 홍수터의 수문특성으로 침수일수(또는 침수빈도)가 있다. 하천 홍수터의 경우는 동일한 하천에서도 홍수터마다 다른 침수 빈도를 보이지만, 댐 저수지의 홍수터는 모두 동일한 침수빈도를 가져 차별성을 확보하기 어려운 문제가 있다. 이에 본 연구에서는 누가침수면적곡선을 이용하여 댐 홍수터의 수문특성을 차별화하는 방법을 제시하였다. 누가침수면적 곡선은 댐 저수지 수위 상승에 따라 침수되는 누가면적을 나타낸 곡선이며, 본 연구에서는 특히 누가침수면적의 비율이 30%, 50%, 70%가 되는 수위를 기준으로 침수빈도를 평가하였다. 본 연구에서는 낙동강 수계 안동, 임하, 영주, 남강 등 4개 댐에서 기 결정된 각 5개의 복원후보 홍수터를 적용사례로 고려하였다. 분석 결과, 누가침수면적곡선은 홍수터의 전반적인 형태(급경사-완경사 혹은 완경사-급경사)를 잘 반영해 줌을 확인할 수 있었다. 또한, 누가침수면적의 비율이 30%, 50%, 70%에 해당하는 침수빈도는 홍수터의 수문특성을 정량화하여 파악하는데 효율적임을 판단 할 수 있었다.

최근의 건축물은 초고층화 또는 지하 공간의 심층화되어감에 따라 과도한 수직 거리 이동으로 인하여 체력이 부족한 사람들이 피난층 비상구에 이르기 전에 지쳐서 쓰러질 가능성이 있다. 화재 발생 인접 구역으로부터의 초기 피난에는 계단을 사용한 후에 나머지 거리는 승강기를 이용하여 안전한 공지나 도로로 탈출하는 방법을 요구하고 있다. 이에 따라 서울특별시 초고층 건축물 가이드 라인에서 피난용승강기에 대해 제정되었다. 최근 층수는 지하 7층 지상53층, 바닥면적 $6,800m^2$ 연면적 $127,050m^2$, 용도는 문화 및 집회시설 판매시설 업무시설 숙박시설(호텔) 공동주택(아파트)의 건축물을 설계하면서 피난용승강기를 별도로 설치하기에는 효율적이지 못하다는 판단하에 승용승강기의 설치기준에 따라 설계된 승강기를 피난용으로 사용하기로 결정하였다. 그러나 이에 대한 세부 설계지침내용이 아직까지 마련되어 있지 않아 국내법과 해외 설치기준을 근거로 승용승강기를 피난용으로 이용하기 위한 설계방법을 정리하였으며, 실제 설계된 도면으로 ELVAC+와 PathFinder의 피난프로그램으로 승강기수와 승강기를 이용한 피난자수의 적정성에 대해 연구하였다.

Purpose: As the improvement in quality of medical environment and the spatial consideration for the prevention of infection in the hospital have become increasingly important in the recent years, specific and practical planning for air conditioning room's area has become a major issue accordingly. However, the air conditioning room tends to be discussed focusing on technical factors such as air conditioning systems that are irrelevant to building plans, while discussions of most departments related to the medical functions have actively taken placed. Therefore, this study aims to investigate the factors influencing the planning for the air conditioning room area, and through subsequent analysis of the area of the air conditioning room, to propose a way to improve effective planning for the air conditioning room area. Methods: This study examines the case hospitals that fall into two types: each floor supply system and concentrated supply system, and compares and analyzes the air conditioning room area-related factors and the characteristics of changes in the interior of air conditioning room before and after remodeling through air conditioning floor plan of those case hospitals. Results: The air conditioning room can be classified into the net area of the functional space such as duct passages, and the public area such as aisle space, and of those the public area is an important factor in calculating the area of the air conditioning room. The public area of the air-conditioning room should not be planned considering only the spaces for mobile passage or maintenance activities, but should be planned taking into account internal changes such as expansion and replacement of equipment in the future from the beginning. Implications: When planning a medical facility, it is used as basic data for the planning of the air conditioning room area, which is a significant fixed factor in the initial setting.

As the population of the elderly increases drastically year by year in Korea, the more welfare centers for them are greatly needed. There are, however, a small number of public geriatric hospitals currently available. And a limited number of private-founded geriatric centers are under construction throughout the country. And the systematic standards for the spacial composition and departmental area distribution for them are not satisfactorily set up yet. The analytical study of the space composition and area distribution of the hospitals in question shows that publicly-shared spaces, such as day-room and lobby, are much more useful for their communications than private spaces, such as shut-in living rooms. It also shows that in-yards or in-gardens which are located in the center of the wards are very helpful for their comfortable long-term hospitalization. The shared spaces are recommended to be in sight of and within earshot of their caretakers. In relation with out-patient departments, the programs for the local elderly residents, such as the day-care center and recreation facilities are recommended to be prepared for their physical care and emotional treatment at a time by municipal welfare centers rather than by private institutions. The analytic study carried out in terms of departmental area distributions reveals that the areas for the wards are generally wider and areas for out-patient/or diagnosis departments are relatively narrower than those in the general hospitals. These area distributions seem to have come from the considerations of their relatively long-term staying in the centers than general hospitals and their mental stability as well.

Purpose: The purpose of this paper is to provide logical basis on enlargement of toilet floor space for the disabled by "ACT ON GUARANTEE OF PROMOTION OF CONVENIENCE OF PERSONS WITH DISABILITIES, THE AGED, PREGNANT WOMEN. ETC" Revised Enforcement regulation [Asterisk 1] (2018.2.10.) and to help with making plans, designs and establishing policies by conducting experimental study with the enhanced floor area regulations. Methods: We conduct Experimental study, field work and interview for this paper. In experimental study, verification of the effective floor area was proceeded by measuring activity space for people in manual wheelchair, electric wheel chair and electric scooter and also reviewed useable area with the space expanded 0.2m both width and depth. In filed work, conducted an observation what other things (ex. sanitary equipment, hand rail and so on) can also affect the active space as well as effective floor space. In the interview, other problems and requirements that were not revealed were experimental study and observation of field work. Results : it's expected to provide better access to toilets for the disabled with the law revision of effective floor area. But, with the usage increasement of enlarged wheel chair and electric wheel chair, expanding side areas of toilet is also highly likely to be required going forward. Implications : Additional research is required on locations of exists and internal arrangement that effect the usage of toilet. It should be led to Universal design by making additional investigation and verification of the users patterns.
