The changes of rural landscape are currently spread everywhere and are rapidily being processed both in quality and in quantities of changes From such aspects, it is urgent to control the land scape change, and is required to know what is valued or preferred in rural landscape, This study was conducted to investigate preferences and differences of the responses between urban and rural residents to rural scenery. As a method, color-slide surrogates for rural landscape settings are shown to urban and rural residents, For a given 52 scenes of rural landscapes the respondents judged the familiarity, orality, and preference along a ten point scale. The following facts are found: 1) Refponses to certain types of landscape settings are influenced by the place of residence of the respondents. The urban residents highly rated natural components of the rural landscape. In contrast rural residents preferred the scenes with visible sign of development 2) The relations among the estimation of preference, familiarity and rurality in rural landscape were deeply correlated. When the rural lands(:ape is adequately ref resented as 'familiarity' or 'rurality' well the landscape is more preferred 3) It is found what is valued or preferred in rural landscape : Readjusted agricultural land, big tree, grassland hi dominated visually were preferred in rural landscape. The implication of this study is that successful planning of development or management in rural area will occur only when these different needs and values are acknowledged and accommodated.

Generally the accident by gas explosion in the working place is occurred at the condition of non-uniform mixture rather than uniform one. This study could predict the explosion phenomenon of non-uniform mixture with model explosion chamber which realize various practical conditions As a result, the mixing level of gas in the chamber depends on discharge area and velocity when there is gas discharge in certain space. In addition, as non-uniform increases, explosion pressure and its increasing rate decrease. However, firing risk after the explosion flame by infrared heat increase due to the increase of residence time of flame.

This paper presents thermal behaviors and performances of a fresh air load reduction system by using earth tube system combined with air-heated solar collector. The earth tube system reduces a fresh air load by heat exchange with soil throughout the year. In the previous experimental research, it was clarified that the earth tube system was very useful as a fresh air load reduction system. However, since outlet temperature of the fresh air which was heated by earth tube system was below 15$^{\circ}C$ in winter, it is not suitable to introduce the fresh air into the place of residence directly. Therefore, a simulation model using the simple heat diffusion equation was used to examine a rising effect of outlet air temperature in winter by combining with air-heated solar collector. An improvement of annual performance by control of operation is also quantitatively examined. In conclusion, it is confirmed that its performance is improved by control of operation throughout the year and outlet air temperature rose by combining with air-heated solar collector.

Industrialization has accelerated the expansion of mobility to the urban areas, land use for function of residence and consumption. With the urbanization, the management and distribution of the physical space of the city and rational design have also become major issues. Rapid and widespread urbanization has consistently accumulated problems of natural, physical, environmental, and psychological circumstances, and most of urban areas have begun to focus on restoring an efficient, safe and healthy urban environment to improve of the quality of life since the latter half of the 20th century, New-Urbanism is a new urban development paradigm that resembles the practical implications of a shared economy for social, economic and environmental cost reduction.. The geographical significance of the sharing city's concept of the alleys is to revitalize sustainable cities while restoring the attractive elements of the city. This study examines the lessons of New-Urbanism in those traditional urban space comparing with each East Asia's cities such as golmok (alley or backlane) in Seoul, Huton in Beijing, Lilong in Shanghai, and Roji in Japan. This study diagnoses whether main principals of New-Urbanism such as development of good community and walkable pedestrian route, restoration of regional identity and sense of the place, and mitigation of climate change strategy can be practiced in the community of alley as well.

Objectives: Stillbirth is a common adverse pregnancy outcome that represents a distressing and traumatic event for women and their partners. The aim of this study was to identify factors associated with stillbirth in ever-pregnant women in Nepal. Methods: This study utilized the individual women's dataset from the Nepal Demographic and Health Survey, conducted in 2016. The dependent variable of interest was whether women had at least 1 stillbirth during their lifetime. The associations between independent variables and the dependent variable of the study were analyzed using a multiple logistic regression model. Results: Among 8918 ever-pregnant women aged 15-49 years, 488 had experienced at least 1 stillbirth during their lifetime, representing 5.5% of the total. After adjusting each factor for the confounding effects of other factors, maternal age, maternal education, place of residence, and sub-region remained significantly associated with having experienced stillbirth. Conclusions: Stillbirth continues to be a major problem among women, especially those with higher maternal age, those who are illiterate, and residents of certain geographical regions. To minimize stillbirth in Nepal, plans and policies should be focused on women with low education levels and residents of rural areas, especially in the western mountain and far-western hill regions.

This study is purposed to analyze of House Vision exhibition and projects in Japan. The contemporary residence has been planned and designed with fixed territory and boundary of rooms. According to the symposium of House Vision, the spatial boundary can be studied in the aspect of territory that molds the experience of residents. So, this study reviews Aldo van Eyck's concept of 'in-between'. Through the analysis, House Vision exhibition is revealed that the housing models present architectural characteristics of middleware and third place. The cognition of internal and external boundary stems from movements and activities of residents. That is the dwelling and residential space determined by users and residents. In this regard, 'in-between' of House Vision has structures(multilayer) causing various relationships to be perceived, so as to connect with the dwelling and activities of residents. As a result, it has relational meanings of sharing, as well as makes possible other community life to be done. According to the projects of House Vision, the units and cores have created the new connections and relationships between privacy and publicity. In conclusion, this research shows a new direction of the spatial strategies on House Vision exhibition in Japan.

A pool scrubber is often used as a wet-type design to mitigate the consequence of a severe nuclear accident. While studies indicated higher decontamination performance of a deeper pool, utilizing a very tall pool can be problematic due to potential structural stability and water backflow issues. This study proposes, as an alternative to a single pool system, a pool scrubber system composed of serially connected multiple pools with lower heights. Since large fraction of aerosol removal takes place in the injection region, serially connected pool scrubber system is expected to enhance the overall decontamination capability of a pool scrubber system. To support the analysis of the proposed system's decontamination capability, a new computer model was developed in the study to describe the bubble size dependent effect on aerosol removal including the effect of pool residence time. The accuracy of the new model was examined against experimental data for its validation. The proposed scrubber system composed of serially connected multiple shorter pools is found to have much improved decontamination performance over the current single pool system design.

The purpose of this study is to identify characteristics of spatial structure of Jiangnan water town in China which has been developed along the water channel. Spatial structural characteristics of the water town, Wuzhen and Nanxun in Zhejiang Province are as follows. First, location of town, spatial framework, lot division, and architectural style get determined by the water channel. The water channel is constructed in cross shape, T-shape, or in combination. Secondly, public space of water town is established along main water channel. Visually and functionally alternating private buildings are established on the water channel side and they are creating unique landscape of Jiangnan water town in overall harmony. Thirdly, residential area is established on the east-west water channel side with southward sunny-faced arrangement and waterside residence is in introvert spatial structure with courtyard but the exterior space is connected with water channel intimately. Fourthly, various spatial components along the water channel enrich the sense of place in water town. The components are corridor with roof, tea house, waterside steps, waterside theater and watergate etc. Uniqueness of place is becoming the core competence in modern townscape. In this aspect, Jiangnan water town with historical and cultural accumulation is suggesting a significant implication. Major implications are as follows. First, promotion of proximity to the water is the basic value that the spatial plan of waterfront needs to pursue. Secondly, mixed use is essential for effective land use and revitalization of waterfront. Thirdly, waterfront plan based on the local uniqueness as the place asset is being required.

This study focused at the local and historical characteristics of Busan from the perspective of local culture, along with the local characteristics of Busan. Busan's local cuisine has been reborn and continues to this day, influenced by the geographical and historical characteristics of the place. Places are not merely spatial points marked by coordinates, but are also semantics that include the human experience and emotional aspects of living in them. A place is a mix of culture, a human response to the visible environment and the environment. An understanding of a place provides a basis for understanding personal geography, culture, and history. .One of the specialties of an area with its location is the local cuisine. Local cuisines are not immutable, as they can change according to the characteristics of the area and the preferences of the residents. Busan's local cuisines reflect the geographical features of the city, and include Busan's historical experiences. First, anchovies and eel are well known for their location as ports bordering the sea. Second, Dongnae Pajeon and Sanseong Makgeolli are made using marine products and grains. Thirdly, during Japanese occupation, fish cake and sliced raw fish was enjoyed by residence in Busan. And finally, Milmyun and Pork Soup, the food made by refugees who came down to Busan and settled down during the 1·4 retreat. The local cuisine, which represents an area, goes beyond simply being eaten, enjoyed, and consumed as a commodity, and is a symbol of the geographical and historical characteristics of the area.
