For a quick and accurate 3D modelling of a building, laser scanning data, digital maps, aerial photographs and satellite images should be fusioned. Moreover, library establishment according to a standard structure of a building and effective texturing method are required in order to determine the structure of a building. In this study, we made a standard library by categorizing Korean village forms and presented a model that can predict a structure of a building from a shape of the roof on an aerial photo image. We made an ortho image using the high-definition digital image and considerable amount of ground scanning point cloud and mapped this image. These methods enabled a more quick and accurate building modelling.

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.

A cross-sectional study was conducted to investigate the prevalence and risk factors for symptoms associated with sick building syndrome in four office buildings located in Seoul. Information on personal factors, job-related factors, and medical history were collected using self-administered questionnaires modified from the National Institute for Occupational Safety and Health Indoor Air Quality questionnaire in 321 office workers in these buildings. The prevalence of general and irritant symptom groups was higher than the prevalence of dermatologic and respiratory symptom groups. Daily total work time, work time in the office, and work time with video display terminals (VDT) were identified as the risk factors for symptom groups associated with sick building syndrome by multiple linear logistic regression analysis. In conclusion, these results indicated that the symptom prevalence in this study is similar with the results reported from previous studies conducted in other countries and work time and work with VDT are related to sick building syndrome in Korea.

한국 고유의 목조건축형태인 한옥을 현대 공법 및 재료 등의 기술의 적용을 통해 품질과 시공성을 향상시키고, 다양한 규모와 시설을 포괄한 신한옥의 형태로 보급 확산하려는 노력이 계속되어 왔다. 본 연구는 신한옥 표준분류체계(Hanclass) 적용을 통해 구축된, 일곱 개의 실증구축사업 사업비 정보를 분석하여 신한옥 공법변화의 추세와 함께 이에 따른 공사비 변화를 고찰하였다. 우선, 일곱 개 실증구축사례의 공법 특징을 분석하고, 이를 공종분류, 재료분류, 공법분류, 부위분류를 분석의 기준으로 설정하여 공사비에 끼치는 영향을 분석하였다. 또한 사례 프로젝트들에서의 공법 변화 주요 영향요인들을 항목화하고 연계된 비용변화를 정량화함으로써 향후 지속적인 공법과 비용간의 관계를 관찰하기 위한 기본 구조를 작성하였다. 본 연구의 결과는 지속적으로 개발되고 있는 신한옥의 신공법의 추세를 체계적으로 파악하고 또한 발전방향의 가이드를 할 것으로 기대한다.

This paper presents the field measurement results of wind effects on a super-tall building (CITIC Plaza, 391 m high) located in Guangzhou. The field data such as wind speed, wind direction and acceleration responses were simultaneously and continuously recorded from the tall building by a wind and vibration monitoring system during two typhoons. The typhoon-generated wind characteristics including turbulence intensity, gust factor, peak factor, turbulence integral length scale and power spectral density of fluctuating wind speed were presented and discussed. The dynamic characteristics of the tall building were determined based on the field measurements and compared with those calculated from a 3D finite element model of the building. The measured natural frequencies of the two fundamental sway modes of the building were found to be larger than those calculated. The damping ratios of the building were evaluated by the random decrement technique, which demonstrated amplitude-dependent characteristics. The field measured acceleration responses were compared with wind tunnel test results, which were found to be consistent with the model test data. Finally, the serviceability performance of the super-tall building was assessed based on the field measurement results.

Objectives : This study was performed to assess the community capacity building ability of health promotion workers of public health centers and to identify influential factors to the ability. Methods : The subjects were 43 public officers from 16 public health centers in Busan Metropolitan City. Questionnaire was developed based on 'Community Capacity Building Tool' of Public Health Agency of Canada which consists of 9 feathers. Each feather of capacity was assessed in 4 point rating scale. Univariate analysis by characteristics of subjects and multivariate analysis by multiple regression was done. Results : The mean score of the 9 features were 2.35. Among the 9 feathers, 'Obtaining resources' scored 3.0 point which was the highest but Community structure scored 2.1 which was the lowest. The mean score of the feathers was relatively lower than that of Canadian data. The significant influential factors affecting community capacity building ability were 'Service length', 'Heath promotion skill level', 'Existence of an executive department', and 'Cooperative partnership for health promotion'. According to the result of multiple linear regression, the 'Existence of an executive department' had significant influence. Conclusions : Community capacity building ability of subjects showed relatively lower scores in general. Building and activating an executive department and cooperative partnerships for health promotion may be helpful to achieve community capacity building ability.

The cover plate and the building loads often make the semi-covered deep excavations with existing buildings bearing asymmetric load, presenting different deformation characteristics with normal excavations, which is not absolutely clear in current studies. Based on a typical engineering, the building storeys, the basement storeys, the pile length, the existence of the cover plate (CP) and the depth of the diaphragm walls (DW) were selected as variables, and 44 groups of simulation were designed to study the influence of existing buildings and the semi-covered supporting system on the deformation of the excavations. The results showed that the maximum lateral displacement of DW, δ_hm, and the depth of δ_hm, H_m, are affected seriously by the building storeys and the basement storeys. Asymmetric structures and loading lead to certain lateral displacement of DW at the beginning of excavation, resulting in different relationships between δ_hm and excavation depth, H. The maximum surface settlement outside the pit, δ_vm, increases significantly and the location, d_m, moves away from the pit with the building storeys increases. δ_vm has a quadratic correlation with H due to the existing buildings. CP and building load will affect the style of the lateral displacement curve of DW seriously in different aspects.
