Large-capacity public transportation systems, represented by urban metro lines, are the key to alleviating the significant increase in urbanization and motorization in China. But to improve the agglomeration effect of metro stations in a more accurate and targeted way requires scientific evaluation and classification of the surrounding areas of metro stations. As spatial and functional design are the core factors for urban renewal design, this study took Beijing as an example, using multi-source data to evaluate the morphology and functional composition surrounding areas of metro stations, and the Boston Consulting Group (BCG) matrix was used to classify and characterize each type of surrounding areas from morphological-functional dimensions. It shows a negative correlation of the mix-use index with the floor area ratio, and only about 20% of the areas achieve the ideal situation of high construction intensity with high mix-use diversity. Hoping to provide a reference for city managers and designers in dealing with the surrounding metro stations with different construction intensities in a more precise way.

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.

Objectives: Busan had the highest mortality and the shortest life expectancy at birth among 16 provinces in Korea in 2008 and there were considerable health inequalities within the region. This study was performed to build up a priority setting framework in Healthy City Busan project. Methods: Analytic hierarchy process was used to determine the relative priority weight for different strategic and program dimensions along with the consistency of response. An on-site workshop-based meeting (calculating importance) and online survey (calculating risk) were conducted to obtain data from 8 experts. Results: The results showed that in strategic criteria "active health promotion & diseases prevention" and "building infrastructure for the Health City project" were two most important factors. In program criteria, considering both importance and risk scores, "making a healthy community" and "building community health centers" in disadvantaged areas were a top priority group. In addition, "enacting an ordinance for the Healthy City", "building the infrastructure for health impact assessment" and "making health care safety net for vulnerable population" were also higher priorities group. Conclusions: Our findings suggest that the Healthy City project in Busan should be focused on strengthening health equity and building infrastructure for sustainability of the project.

The Leadership in Energy and Environmental Design (LEED) has provided abundant resources and guidelines for a new project to become a sustainable anchor in the neighborhood. Paired with a range of checklist, LEED has strong influence on the standards for a sustainable building, and it also has played an iconic role in energy-efficient architecture. However, it is still unclear as to whether or not an LEED certified building enhances environmental benefits to its surroundings. If an LEED certification promises a baseline for an eco-friendly building, then a group of these structures should ensure significant environmental benefits to the society. This is the main question of this study, and the authors answer this hypothesis by examining the relationship of LEED certificates and their influence on outdoor temperature, especially in terms of urban heat island effect. The goal of this paper is to analyze the influence of the LEED certification on urban temperature as an indicator of sustainable architecture's regional interactions. If an LEED certificate is regarded as a strong contributor to a sustainable built environment, then a group of these certificates should result in greater benefits to society. To this extent, the authors question if there is any possible relationship between a large concentration of LEED certified sites and the temperature of their surroundings. To properly assess the research direction, Global Moran's I analysis, Local Moran's I analysis, and Hot Spot analysis are implemented to find the clustered areas of LEED certified buildings. For examining relationships between clustered area and its temperature, correlation efficients are calculated.

In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

Recently, the installation of photovoltaic modules in urban areas has been increasing. In particular, the demand for solar modules installed in a limited space is increasing. However, since the crystalline silicon solar module's size is proportional to the solar cell's size, it is difficult to manufacture a module that can be installed in a limited area. In this study, we fabricated a solar module with a shingled design that can control horizontal and vertical width using a bi-directional laser scribing method. We fabricated a string cell with a width of 1/5 compared to the existing shingled design string cells using a bi-directional laser scribing method, and we fabricated a solar module by connecting three strings in parallel. Finally, we achieved a conversion power of 5.521 W at a 103 mm × 320 mm area.

The Case Study prepared by PCPA and Lift Group will identify a growing development problem in urban areas; high value project sites that are restrictive in size or "tight" are underutilized and underdeveloped. In an effort to remedy this problem, our team will evaluate a design program through the lens of both conventional construction and Core Cantilever Construction. It is also important to differentiate between Core Cantilever construction and the plagued "Lift Slab" construction method as they may be confused, due to the top down construction sequence. This article will demonstrate that constraints inherent to conventional construction techniques prohibit economically viable development of these project sites, while Core Cantilever construction methods increase the projects value by reducing construction timelines and increasing the useable floor area.

In recent years, the architectural interest in the apartment design has been getting focused on qualitative improvement and design differentiation. Especially the facade design differentiation is one of the most important elements in this matter. The purpose of this study is to provide the basic informations that can be referenced when architects are dealing with exterior design by analyzed design types and characteristics of apartment entrances. Target apartment of this study was whasung dongtan the 2nd phase new city districts which was planned to solve a housing shortage in the capital region. Having examined eleven pilot districts, four 1st construction areas, and eight 2nd construction areas, - total 23 complexes - 282 apartment entrances in 212 apartment buildings were carefully researched. Apartment entrance design can be divided into 15 different design elements: design types and combination types, direction, shape, height, approach types, exterior wall finishes of entrance, exterior wall finishes of lower parts of apartment, handrail types of slope, floor finishes of slope, distribution ratio of piloti, ceiling height of piloti, floor finishes of piloti, space use of piloti, window establishment between piloti and elevator hall, landscape elements of piloti. Design characteristics of building entrances were also analyzed in 4 groups (I, II, III, IV) divided by construction contractors ranking. In conclusion, first, design types and combination types can be classified into 15 different kinds, and the group I and II tend to show wider variety of entrance combinations. Secondly, the height and volume of extrude entrance type tend to increase in the group I and II. Third, the spatial configuration of pilotis appears to show more of 'pass + store + break' rather than 'access', as we get closer to the group I.
