Each municipality is promoting signboard improvement projects, but the effectiveness is not great. The main reason for this is that when the signboard is manufactured the location of the shop is only dependent on the visual aspiration effect and it is not harmonized with the building by applying uniform design. The signboard are installed almost everywhere in the city, such as residential, natural and commercial environments. And the signboard provides various services such as traffic information and life safety to customers. Also, by applying design and functional elements, we can enhance the competitiveness of companies and improve the urban environment by enhancing the mutual connection effect of customers and space. The purpose of this study is to investigate the effect of design elements and functional elements of the signboard on customer preference. In other words, we conducted surveys and analyzes of 152 specialists and non-experts (customers, self-employed). As a result of the study, the following conclusions were drawn. First, the functions and design elements of signboards are important factors that have a positive effect on customer preference. Second, the function of the signboard has a positive(+) influence on the customer preference, and the information providing function and the corporate image side function directly affect the customer preference. Third, color elements have a positive(+) meaningful effect on customer preference. Especially, similar color sign affects customer preference positively. Fourth, the signboard design component has a positive(+) significant effect on customer preference. In particular, typefaces have a positive effect on customer preference.

Malaysian modern housing typologies (such as bungalows, semi-detached houses and terrace houses) are influenced by international style and constitute unique regional characteristics because they are modified in accordance with climatic conditions and unique social, ethnic housing cultures. This research identified unique characteristics and planning principles of how rooms and spaces of a house are related and organized into coherent patterns of form and space. For the analysis, we surveyed twenty-two residential precincts that identified twenty-five unit plan types for landed properties built in Ara Damansara, Malaysia. The methodology adopted in this study consisted of a document review and field surveys. It is difficult to find unique characteristics of space organization (except for the location of bathrooms) because the form of terrace houses is standardized and limited in design from the aspect of space organization. However, the organization of bedroom space and kitchen space has strong regional characteristics that have become stereotyped for semi-Ds and bungalows. General guideline for areas of unit plans are proposed based on the results of area analysis. We also found that the areas of L + D and MB increase as the total area of the house increases; however, the remaining rooms do not increase in area as long as they satisfy appropriate standards due to the addition of multi-purpose extra rooms. This study only examined limited cases in Ara Damansara and it is difficult to generalize the findings of other new towns in Malaysia. Nevertheless, it is worthwhile to collect and systematically organize data according to typologies. Finally, the authors were able to understand the unique regional design factors to be considered for landed property housing planning in Malaysia.

Urbanization and industrialization have led to a severe deterioration in urban air qualities. As an air pollution is closely associated with human health, citizen has a growing concern about the air quality policy to improve their residential environment. Due to the recently advance in web- and mobile computing technologies, citizens can easily access various air quality information and public authorities utilize the social media service to communicate citizens with air quality issues. Also citizens' participation and role has been increased to improve urban air qualities. Thus, to meet the technical and societal changes, a GIS-based air quality information system is developed based upon the Ubiquitous Public Access (UPA) model in ISO19154. The proposed system employs the context information model to provide air quality information depending on citizens' health conditions and locations. Also, citizens can present their perceptions of an air quality at their current location Public authorities can thus utilize the citizens' perceptions when establishing new air quality policies.

The high intrinsic water content and salinity of food waste prevent a smooth composting process and consequently cause social, economic and environmental problems. In this study, we investigated the distribution of the water content and salinity in food wastes to obtain useful primary data to ensure adequate and quality recycling. A total of 300 food waste (FW) samples were collected from residential apartments (home generated FW), a wide range of restaurants, i.e., restaurant generated FW that included Korean, Chinese, Japanese and western FWs, and several places that included food waste processing facilities (dehydrated FW cakes). The collected food wastes were oven dried for 48 hours at 80℃ after which the water and salinity contents were analyzed. The results show that the average water content of the FWs was 72.45 ± 10.51%, and the average salinity content was 2.03 ± 0.57%. Furthermore, the salinity of the collected FWs was characterized by where the FW was generated. By location, the salinity concentration of home generated FW was 2.30% while western food had the lowest salinity concentration of 1.18%. However, dehydrated cakes had the highest salinity concentration of 2.84%. Especially, the distribution of the salinity content in food wastes can form the basis for improving the compost quality in food waste recycling.

This study was aimed to assess the degree of addiction on computer games and find factors related to game addiction, health perception and health promoting behavior in elementary school students. A study subjects were 814 students in 5th and 6th grades at 4 elementary schools in a city and a county. The items in questionnaire was consisted of general characteristics, circumstances and habits related to utilization of computer and internet game playing, and degree of addiction, health perception and health promoting behavior. We analyzed data using chi-square test, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, addictiveness on internet game was significantly related to type of computer utilization, frequency and duration of internet game playing, gender, after-school activities, grade points, economical status, and location of computer in a house. Health perception was significantly related to addiction points, gender, residential area, and grade points. And health promoting behavior was significantly related to addiction points, grade level, grade points, and health perception points. Since health promoting behaviors of children in elementary school are in the way of making, their degree of addiction to computer games can greatly influence their attitude towards health and their future life pattern as adults. Therefore an educational prevention program including counselling on game addiction should be devised. And researches will be needed for developing the Korean standard for measuring degree of addiction and a prevention program for peer group's game addiction.

Objective: Emissions of volatile organic compounds (VOCs) from municipal wastewater treatment plants and industrial wastewater are often overlooked as sources of exposure to toxic chemicals. VOCs from such sources evaporate readily into the air and may have significantly adverse impacts on public health. The present study aimed to establish the concentration of VOCs released from Jangrim-sinpyoeng Municipal and Industrial Wastewater Treatment plant (JWTP) in Busan, South Korea and assess the causes of the odor/stench in the surrounding residential facilities. Stench intensity, frequency and release time, and wind direction were also monitored. Methods: Onsite data were collected on a daily basis from a laboratory located on the JWTP premises through a period spanning 2006 to 2010. A second set of data was obtained in 2006 by conducting a questionnaire survey with 210 respondents living near JWTP. The experimental and survey data were analysed statistically using the SPSS package. Results: The survey results showed that people residing around JWTP strongly perceive a stench from the plant. The intensity of the stench was influenced significantly by wind direction and the location of the apartments facing the JWTP. Public participation formed a significant step in determining the quality of the study environment. Conclusion: Onsite data and survey data obtained in 2006 indicate that the nature of the odor experienced by residents is due to the intensity of total VOCs released by JWTP. However, additional research is needed to determine the effects of the VOC pollution on public health and quality of life.

Recently, park usage for environmental education has gained popularity in Seoul. Therefore this study was performed by analyzing the status and problems of nature classrooms in neighborhood parks and citizen's parks that are located in residential areas in Seoul, and then by suggesting improved methods and user programs. The results of this study are summarized as follows. 1) 18 out of 281 neighborhood parks and citizen's parks have nature classrooms in Seoul. Facilities of nature classroom are comprised of direction signs, plant name card, pond, pavilion, pergola, bench, green house, waste baskets, lighting, drinking fountain and others. However, they have many problems in terms of quality. Nature classrooms were classified into three types according to their location in each park. Among the three types, the most popular type was the one that is a part of a park A Total of 479 species of plant (155 species in tree, 324 species in herb) were planted in nature classrooms. There are many kinds of environmental education user programs, but these are not connected with the nature classrooms. Most nature education programs in nature classrooms were self-guided. 2) The Problems that appeared were the featureless place composition, a lack of programs related to nature classrooms, access restriction to certain natured areas, and so on. 3) Finally, this study suggests some solutions to the problems of nature classrooms in urban parks. The solutions include full access to the parks, the creation of diverse theme, and setting up interesting panel and leaflets in order to encourage more active self-guided education.

The improvement of adaptation capability against heat island (ACHI) by greening buildings is considered as an important measure to cope with a climate change. This study aimed to select the most appropriate zones for green roof initiative in case study sites, Bucheon, Anyang, and Suwon Cities and to investigate the characteristics of buildings for greening to improve ACHI. Relative ACHI for each lot was estimated from 0 to -9, assuming that it decreases with the distance from green space and waterbody. Low adaptation capabilities were mostly shown in the old urban blocks with dense low-rise buildings and lack of green space. Three blocks with the lowest ACHIs were chosen as a green roof initiative zone in each city. They are largely residential areas including low-rise buildings such as single, multi-household houses, townhouses, 5 or lower story apartments and few are industrial areas crowded with small factory buildings. The areas of building roof available for greening are 8.8% within the selected zones in Bucheon City, 5.3% in Anyang City, and 4.9% in Suwon City. As it were, 25.2~41.7% of the roof top areas are available for greening in these zones. It means that roof top areas of $25,000{\sim}120,000m^2$ can be used for greening within the selected zones of $0.64{\sim}1.65km^2$ to improve ACHI. The approach and results of the study are significant to provide a logical basis and information on location, scale, effect, and target figure of greening as a measure to cope with climate change.

Regarding the developmental plans for the coastal areas and marine architectures, this study deal with the overall planning of apartment complexes in waterfront areas, focusing upon the analysis of their comfort and convenience factors from the perspective of the potential residence. It also analysis the intra-complex comfort and satisfaction conditions in terms of their floor-by-floor, directional. and location factors. The results of the study are as follows: 1) The order of respondents' preference on directional factor has been found to be: South > Southeast > Southwest > East > others. 2) 67% of the people surveyed on scenery responded that outward view is considered more significant than the directional factor. 3) A comprehensive analysis of floor zone-specific view preference shared that there were only minor differences among quay wall, arc, and river-seashore types. The impact of the characteristics of the marine environments turned out to be a greater point of consideration; showing that the other of floor-preference is: high-level > ultra-high level > middle level > low level.
