최근 친환경건축물인증제도, 주택성능등급표시제도를 비롯하여 실내공기환경에 대한 기준, 친환경상품인증기준 등 환경관련 제도 및 규정이 마련되면서 공동주택의 신축 및 리모델링 공사에 이에 대한 고려가 필요한 상황이다. 특히 공동주택 리모델링 공사는 거주자가 사전에 정해진 상태에서 공사를 진행하므로 이들에 대한 의견수렴과 사용되는 소재에 대한 요구분석이 신축에 비해 중요하다는 특성이 있다. 하지만 현재 국내에서 시행 중에 있거나 최근 완료된 리모델링 공사의 시공자는 친환경 소재 적용에 대한 거주자의 적극적인 의견수렴 과정이 미비하였고, 친환경상품인증원의 최우수 등급을 받은 친환경 제품을 거주자의 요구에 의해 적용한다기 보다는 공동주택의 홍보의 일환으로 사용하고 있는 실정이었다. 또한 공동주택 리모델링 거주자는 친환경 제품의 인증기준에 대한 이해가 부족하여 친환경 제품의 등급을 맹목적으로 신뢰하는 경우가 있었고 적용되는 친환경 소재에 대한 요구가 매우 정성적인 특징이 있다. 따라서 공동주택 리모델링 거주자의 친환경 소재에 대한 요구사항을 조사하고 이를 정량적으로 분석하여 만족도를 극대화 할 수 있는 친환경 소재를 리모델링 공사에 적용하여야 한다.

The wooden building is mainly damaged by the termite which have an effect of the structure by making emptied inner part of wood. One class, Japanese termite, inhabits throughout Korea and is often detected. So the deterioration by termite attacking the wooden building needs to be controlled. Termites are over 2,800 species in the world, usually they inhabit in the tropical or subtropical region and don’t over winter in dormant condition. So their activity and distribution are chiefly restricted by temperature and humidity. The termite inhabiting in Korea is Reticulitermes speratus kyushuensis Morimoto, which known to have an optimal temperature range at $12~30^{\circ}C$ and minimum temperature at $6^{\circ}C$ for activation. These temperatures correspond to the mean temperature($5.6^{\circ}C$~$25.8^{\circ}C$) from March to November and the activity time of termitein Seoul. In addition, as a result of environmental pollution by industrial development, the climate of Korea is getting warm. The increase of mean temperature in Korea has been $1.1^{\circ}C$ for the past seventy five years, so it is expected that the damage of wooden building by termite will increase gradually. Therefore, in order to protect wooden building from damages by termite, it needs not only development of new pest control methods, but also studies on the control of environmental factors having an effect on the activity and growth of termite. For the conservation of the large cultural properties such as the wooden building in the open air, it would be effective to use the methods of fumigation, insecticidal and antiseptic chemical treatment of wood materials, soil termiticideinjection treatment, and termite colony elimination system.

This paper presents results from analysis of architectural plan drawings of 355 elementary schools recently designed for 4 years. Theses plans are analyzed by factors such as local distribution, number of classes, type of plan, total construction area, area per a class, area per a student, and area status of each space. The purpose of this study is to provide fundamental resources for architectural designing and planning of elementary schools through finding trend and status of elementary school buildings that have no detailed data of area index. The results of this study are as follows: 1. As a result from analyzing number of classes in the surveyed schools, schools having 36 classes are dominant and schools having 72 classes are also shown. Average number of classes is 34.1. This result reflect s that elementary schools have been planned as large-scale schools. 2. In terms of type of plan, we found out that instead of disappearing traditional single corridor type building, the open school building that have multi-purpose spaces are mainly designed. In addition to that, there are few schools with large class rooms. 3. In the status of area of each school, they have much larger areas than areas provided by building guidelines. Secondly, there are some schools with two times area difference even though they have same class number. Therefore, it needs to adjust the school building guidelines to practical needs in the consideration of elementary school building for compulsory education. Though the plans of recently designed school for 4 year s are more differentiated than past, there are few schools planned by appropriate plan design and area distribution scheme. As a consequence, some improvements like improvement of building guidelines are desperate.

Modular construction is a construction method whereby prefabricated volumetric units are produced in a factory and are installed on site to form a building block. The construction productivity can be substantially improved by the manufacturing and assembly of standardized modular units. 3D printing is a computer-controlled fabrication method first adopted in the manufacturing industry and was utilized for the automated construction of small-scale houses in recent years. Implementing 3D printing in the fabrication of modular units brings huge benefits to modular construction, including increased customization, lower material waste, and reduced labor work. Such implementation also benefits the large-scale and wider adoption of 3D printing in engineering practice. However, a critical issue for 3D printed modules is the loading capacity, particularly in response to horizontal forces like wind load, which requires a deeper understanding of the building structure behavior and the design of load-bearing modules. Therefore, this paper presents the state-of-the-art literature concerning recent achievement in 3D printing for buildings, followed by discussion on the opportunities and challenges for examining 3D printing in modular construction. Promising 3D printing techniques are critically reviewed and discussed with regard to their advantages and limitations in construction. The appropriate structural form needs to be determined at the design stage, taking into consideration the overall building structural behavior, site environmental conditions (e.g., wind), and load-carrying capacity of the 3D printed modules. Detailed finite element modelling of the entire modular buildings needs to be conducted to verify the structural performance, considering the code-stipulated lateral drift, strength criteria, and other design requirements. Moreover, integration of building information modelling (BIM) method is beneficial for generating the material and geometric details of the 3D printed modules, which can then be utilized for the fabrication.

The commercial buildings greening can generate multiple benefits to achieve a sustainable building and business environment. However, a comprehensive systematic review of commercial buildings greening across multiple disciplines has yet to be reported. This study conducted a systematic analysis of 39 literature on commercial building greening from Web of Science over the past 19 years and utilized CiteSpace to visualize the academic evolution and trends in this field. Key findings were: 1) The number of publications in the past five years has increased, indicating that commercial building greening research has received widespread attention. 2) The large number of publications means that the research field of commercial building greening is relatively broad. 3) The study of commercial building greening has become a global participation and cooperation research topic. The top cooperating countries mainly come from the United States and Europe, while the differences in cooperation between institutions in developing countries are less significant. 4) The greening of commercial buildings is more related to research on behavioral activities. 5) The research on commercial building greening has developed from architecture and plants to interdisciplinary fields, including psychology, economics, and management. 6) The cost of commercial buildings greening is generally an obstacle to installation. This study provides specific references for stakeholders and plays a crucial role in determining the evolution of commercial building greening research and predicting future research needs and opportunities.

This study examined the needs analysis of school-based staff development at the elementary school level in rural areas of Kyungki and Chungnam provinces. Using a modified survey, the Korean School-based Staff Development Needs Assessment Survey (KSSDNAS), adapted from the Teacher Needs Assessment Survey (TNAS) developed by Gary M. Ingersoll et al. and the Korean Teacher Needs Assessment Survey (KTNAS) developed by K. Chung, the study analyzed 192 teachers' responses. In order to analyze the data, frequency, factor analysis, cross-tabulation, and one-way ANOVA were computed. The findings of this study indicated that there were significant differences between years of teaching experience and the teachers' perceptions of school-based staff development needs. These involved "building learning objective and learning group "and" cooperation of classroom management and students' activity". However, elementary school teachers' perceptions of their school-based staff development needs were not significantly influenced by school size or school location. Most of all, it may be suggested that active teachers can improve the achievement of their rural schools by rearrangement of the subject contents and by understanding their students in rural areas.

The purpose of this study is to obtain basic data for making performance criteria about the structural safety of lightweight dry wall later by examining types and characteristics of horizontal load acting on the wall. The subjects applying horizontal load to the wall are human and objects. The types of horizontal load are classified as static load and dynamic load depending on the difference of acting time. The magnitude of horizontal load "0.25kN/㎡" defined by KBC 2009 has no significant meaning since it is the unsubstantial nominal load. The result of examining types and characteristics of horizontal load is as follows. (1) Static load by human needs to have more systematic investigation including differences in wall hardness and human weight. (2) Dynamic load by human needs to raise the significance of study result by increasing the number of subjects. (3) Dynamic load by objects needs to accumulate the load specific data for various load subjects considering real situations.

In order to plan and manage public facilities effectively and efficiently, it is necessary to diagnose the current status of facilities and decide the objective features. Performance measurement is to provide managers with the information they need to measure competitive advantages. This paper discusses public facility performance in order to establish the conceptual framework for performance measurement for public facilities. In order to develop the measurement of public facility performance, a pilot study was conducted with facilities managers of facilities management corporation of public districts in Seoul. We investigated how public facilities management teams have assessed their performance and collected data regarding financial aspects, service aspects, community aspects, and building aspects. There is no standard format to measure facility performance since building sizes, programs, community needs widely differ. However, it is necessary to have a more consistent system to measure facility performance. In addition, each public municipal district needs to empower each district facilities management corporation to participate in managerial decisions and budget control.

In 1990’ idyllic housing complex is spreading surrounding metropolitan areas of Korea as a result of needs for quality change of housing environment, which was caused by the increase of income, the spread of cars and the change of working environment. On the contrary to the idea of idyllic housing, however, while it is just surrounded by natural environment, it has some critical problems such as the lack of public facilities and its development which often damages the nature. The row houses which this study deals with are popular with working class especially in Europe as an idyllic urban housing. It is noticeable that they have separate private gardens which satisfy the residents'basic needs and save lot areas and building costs more than detached houses. This study intends to suggest row houses as an appropriate housing type for environmentally friendly housing in Korea through the analysis of cases of row houses.
