  • This paper aims to clarify the residential quarter organization and housing spatial form of fishing village in Eocheong-do Island. The results are as follows. First, island residential quarter is formed along the coastline, the detached house and the shop house are mainly located in the front of the coastline. Second, the inclination road which connects the northernmost end part and the seashore road is maintained as a road system of a residential quarter from the Japanese colony term until now. Third, It is the feature that Eocheong-do island has the wide width of the front of a site compared with other island residential quarters. Therefore, the frontage wide of a building is also large. Fourth, the entrance of the building where the frontage is mainly located right in the middle, and each rooms are located in the surroundings of it. Finally, the typical community space of Eocheong-do island is Pyeongsang(平床). Pyeongsang is space which receives various functions in inhabitants' life cycle.

  • Running tests on roads were conducted to clarify the influences of road infrastructure, traffic condition and vehicle's emission level to the amount of emission at local roadsides, and to reveal the operation patterns which can reduce the emission peaks. NOx emission peaks of two light duty freight diesel vehicles which have different emission levels were evaluated by using an on-board measurement system. Tests were carried out with various payload conditions and road conditions. As a result many NOx emission peaks were observed when the vehicles were starting or accelerating at intersections. The test vehicle which has higher emission level caused higher frequency and level of NOx emission peaks. Shifting up at lower engine speed in combination with lower acceleration brought out not only reduction of NOx emission peaks level but also of $CO_2$ mass emission.

  • To analyzed ride quality and to predict durability in vehicle dynamics, it is essential to describe a road surface profile precisely. This paper presents a technique to generate road surface profiles in a spatial domain by using a power spectral density function. A single track power spectral density function is proposed to describe a road surface profile, which is also applicable for multi-track vehicle response analysis, The derived road surfaces are compared to ISO(International Organization for Standardization) standards and classifications, proposed by the MIRA(Motor Industry Research Association). The methodology in this paper is also proposed to generate road roughness description with a limited external data. A small amount of external curve data is combined with an internal PSD function to generate road surface roughness in a spatial domain.

  • We propose a semantics filter aimed at filtering unnecessary data for a user. In the Geographic Information Systems (GIS), transfer of spatial data for each user is one of the important problems. We design a system that filters spatial data by using user's information adaptively. Our system derives the degree of geographical knowledge and the priority of buildings by using fuzzy reasoning. Furthermore, this system computes the priority of roads by deriving the contiguity relation between a building and a road. This paper describes a method for filtering of spatial data.

  • Pax Sinica is a historiographical term, modeled after the original phrase Pax Romana. It refers, in Latin, to a Chinese-provided peace which in turn is used to describe an era of peace in East Asia sustained by Chinese hegemony. In historical terms, both the Pax Sinica of the Eastern hemisphere through Han China and the Pax Romana of the Western hemisphere through Rome signified a trans-regional order based on rules and regulations. This orderly world of the Pax Sinica generated a number of positive results such as the intensification of travel, ever-expanding trade relations, an increase in the overall living standards of the populace, the proliferation of cities, and a demographic upsurge in Eurasia along the ancient Silk Road. During this period, China was the dominant civilization not only in the Eastern hemisphere but also in the Middle hemisphere due to its political, economic, military and cultural influence. This paper aims to reintroduce this historiographical term to elucidate the recent Chinese initiatives in Eurasia along the Silk Road to facilitate the integration and connectivity of the continent.

  • This research is to analyze the spatial organization of a traditional rural community and its characteristics, the case of Hanbam village located in the north of Daegu city. The conclusions of this study are as follows; 1. The difference between private space and public space in the residential area of Hanbam village is obvious, and these two spaces are organically related each other by means of road. These spaces have some spatial characteristics of organization, such as center, hierarchy and sequence. 2. The private space consists of a residence module and a farming area in the settlement, and it is clearly farmed by the firm fence of rocks and by surrounding roads. Fruit-bearing trees such as Pyrus pyrifolia, Cornus officinalis, Diospyros kaki, Juglans sinensis are planted at the boundary. And most of residences are composed of a building, a inner court and farming fields. 3. The public space for the community mainly functions as ‘a meeting place’for residents, and consists of recreational spaces, ceremonial spaces, community facilities, and social facilities. Among these, Jeong-ja(pavilion), Seong-an Soop(forest) and Dae-chong(building for common use) are of great cultural value as important traditional spaces. 4. Two kinds of road are commonly fecund in the village; spontaneously generated one and planned one. This is straight inner streets and access paths to the village, and that is curvilinear alleys which are connected to Dae-chong, the core of village. Also stone walls and climbing plants on them are major elements of village landscape.

  • The World Health Organization(WHO) has reported the sleep disturbance as one of the adverse effects of noise. And the effect of combined noise sources on human have been investigated because community noises are seldom heard and are concurrent. Therefore, the effects of combined noise source and its S/N ratio on sleep disturbance were investigated; as a single noise source, road traffic noise was selected, and construction and movie noise were combined with road traffic noise. Tests for sleep disturbance were conducted in bedrooms and the effect on each subjects' sleep was evaluated by questionnaire. The results showed that the rate of awakening increased slightly only when the SPL of construction noise was 10 dB higher than that of road traffic noise. It was also found that the sleep disturbance was affected by the type of combined noise sources and its S/N ratio.
