The aim of this study is to find what architectural restoration and street-scaping conservation of early settlement in Virginia, which have processed on the style of 18th centuries. One of the settlements in Virginia was Williamsburg that located in the high land between Jamestown and Yorktown. In 1698, the capital of Virginia was moved from Jamestown for the safer environment. At that time they constructed the town like a small urban that had a straight-lined Duke Glocester Street, Georgian style buildings, and landscapes of 18th centuries. Before 1928 the village was flown into ruins, but Rector of the church, Dr. W.A.R. Goodwin, understood the value of reservation to restore the village as colonial architectural style that has an original figure. John Rockefeller Jr. has taken part in his restoration of colonial style of architecture and culture. This paper surveyed nine cases of buildings and srtreet-scape on Duke Glocester Street. Most of the buildings on the street have a proposition, balance, and equipment of Georgian architectural facade in 18th centuries. The conclusion has three points. First, the Williamsburg has been reserved as an early colonial settlement through the restoration of architecture and street-scape design. Second, main architectural style is a Georgian form that has a balance, proportion, and simplicity of facade. Also new buildings and additions of architecture have to keep 'Design Review Guideline of Colonial Williamsburg' in order to contribute the existing colonial buildings. Third, the main street-scape, Duke Glocester Street shows Georgian architecture and cultural life pattern with tradition.

In soft ground the settlement criterion usually governs. Therefore, it is very important not only reasonable assessment of the allowable bearing capacity of the soil but also reasonable assessment of settlement. In the previous studies by many other researchers, load concentration ratio and settlement reduction factor are usually proposed for estimating the settlement of granular compaction piles. In the previous studies, the reinforced ground with granular compaction piles is simplified as composite ground and the analysis is performed with in the basis of this assumption. However, the lateral deformation of granular compaction pile could not be considered and only the relative vertical strength between pile and soils could be considered in the analysis. In this study, a method adapting the Tresca failure criterion is proposed for calculating settlement of granular compaction pile. Proposed method can be considered the strength of pile material, pile diameter, installing distance of pile and the deformation behavior of vertical and horizontal directions of pile. In the presented study, large-scale field load test is performed and the results are described. Also, predictions of settlements from the proposed method are compared with the results of the load test. In addition, a series of parametric study is performed and the design parameters are analyzed.

The behaviour characteristics of Granular Compaction Pile(GCP) are mainly governed by the lateral confining pressure mobilized in the matrix soft soil to restrain the bulging failure of the granular compaction pile. The GCP method is most effective in soft soil with untrained shear strength ranging from $15\sim50\;kPa$. However, the efficiency of this method is falling down in the more compressible soil conditions, which does not provide sufficient lateral confinement. In the present study, the GCP method reinforced with uniformly graded permissible concrete is suggested for the extension of application to the soft ground. Also, large triaxial compression tests are conducted on composite- reinforced soil samples for verification of availability of the suggested method and the settlement estimation method of the reinforced GCP is proposed. Further, for the verification of a validity of the proposed method, predicted settlements are compared with results of numerical analyses. Tn addition, parametric studies are performed together with detailed analyses of relevant design parameters.

Recent settlements and sinkhole openings in urban areas have caused social problems such as damage to roads and structures, fear of the public, and loss of property. Several studies have demonstrated that surface subsidence and sinkhole opening are greatly affected by rainfall and rainfall intensity in urban areas. In this paper, we analyzed the relationship with the characteristics of recorded rainfall data using the ground subsidence database reported in major cities. The correlations were found using sedimentation and precipitation data from 2010 to 2014. The duration and intensity of a given precipitation have evolved to obtain an effect on ground sedimentation rate (SR). The results show that the relationship between SR and precipitation is asymptotic and can be modeled by a hyperbolic equation. Through this study, it is possible to predict the occurrence of ground subsidence due to precipitation in advance.

The objectives of this paper were to investigate home range, habitat selection, and threat factors of leopard cats (Prionailurus bengalensis) living in rural area of Korea. The results based on radio tracking of three leopard cats (two males and one female) can be summarized as follows. First, the average home range of leopard cats were $2.64{\pm}1.99km^2$ (Kernel 95) and $3.69{\pm}1.34km^2$ (MCP 100), and the average size of core areas was $0.64{\pm}0.47km^2$ (Kernel 50). The home range of a male leopard cat that radio-tracked in winter was the largest ($5.19km^2$, MCP 100). Second, the Johnson's habitat selection model based on the Jacobs index showed that leopard cats preferred meadows and paddy fields avoiding forest covers at the second level, whereas they preferred meadows adjacent to streams and avoided paddy fields at the third level. Finally, roadkill could be prime threat factor for the cat population. Therefore, habitats dominated by paddy fields, stream corridors with paved roads, and human settlements with insufficient forest patches could threaten the long-term viability of leopard cat populations. Thus the habitat managements for the leopard cat conservation should focus on the prevention of road-kill and the installation of wildlife passages in rural highways adjacent to stream corridors.

Background: Smoking is a learnt behavior during adolescence and understanding the factor/s associated with smoking will assist in identifying suitable measures in combating the rising prevalence of smoking among adolescents. This research aimed to identify the factor/s associated with smoking among form four students in Kota Tinggi, Johor. Multistage sampling was used to select a representative sample of students in 2008 and data were collected using a self-administered validated questionnaire. This study revealed that the overall smoking prevalence was 19.0% with a significantly higher proportion of male smokers (35.8%) as compared to females (3.15%). Adolescents who were male (aOR 6.6, 95%CI 2.61-16.4), those who had peer/s who smoked (aOR 4.03, 95% CI 1.31-12.4), and those who studied in rural areas and Felda Settlements ( aOR 4.59, 95 CI 1.11-18.0; aOR 9.42, 95%CI 3.91-29.1) were more likely to smoke in the past one week. On the other hand, adolescents with better knowledge on the hazards of smoking and negative attitudes towards smoking were less likely to smoke (aOR 0.51, 95%CI 0.37-0.72; aOR 0.67, 95%CI 0.46-0.99). Future promotional and interventional programmes on smoking should be considered and the above identified risk factors integrated to reduce smoking prevalence among students of school-going ages in Kota Tinggi.

Recently, China has brought many political, economical, and ideological changes in order to complete the "socialistic market economy." In terms of legal system, they make much effort to seek compatibility and stability of law and order. China recognizes that the breakdown of corruption, which is rampant in society, is an essential short-cut for national development. To realize anti-corruption reformation, it strengthens the supervision of relatives and close officials of high-ranking government officials. Recently, China has suffered from expanded trade disputes internationally and has also experienced severe management-labor conflicts domestically due to economic recession. From 2012 onward, civil lawsuit and other litigations have increased sharply. Also, they face severe conflicts in the land system. It is expected that many disputes arise due to speculation on rural housing. Meanwhile, Mongolia expands the size of trade with Korea in mutual cooperation since their diplomatic relation in 1990 by entering more than 20 treaties and agreements. As Mongolia has rich natural resources and Korea is equipped with advanced science and technology, the two countries have opportunities to develop mutually beneficial cooperative relations. Recently, the arbitration system has attracted attention instead of litigation as a means of dispute settlement in line with the expansion of trade between Korea and Mongolia. This study would be helpful to figure out desirable methods for dispute settlements in case of trade disputes among Korean companies that would advance into China and Mongolia.

Coworking spaces have been increasingly considered as a way of building an innovative entrepreneurship ecosystem and facilitating population inflow. This paper aims at identifying the concept and characteristics of coworking spaces and examining these various types in a regional context. Coworking spaces located or planned in small and medium-sized cities and rural areas in Japan and Korea are empirically investigated. Through the case study, this study provides implications for a model of coworking spaces being a creative community in a region. Specifically, it is necessary to have distinctive features only for the regional context-based coworking spaces. Moreover, this new spaces should act as a multi-functional, convergent space and a venue for regional innovation. In a fast-changing work environment such as telework, the region-based coworking spaces can be reconsidered as the place that provides an alternative work, play, learn, and rest platform. Creative people hoping for new work and lifestyle may flow into the region through this intermediator, and thus foster the interplay between the creative community and regional environment.

This study aims to examine various discourses of the urban landscape discussed in the fields of new cultural geography, spatial political economy, and landscape architecture in order to propose a theoretical framework for the interpretation of a contemporary urban landscape. The notion of landscape is a modern idea that separates humans, especially the bourgeois subject, from nature, and then achieves the visual possession of nature. New cultural geographers have studied the political aspects of landscape. According to them, landscape as materialized discourse is "a way of seeing" which includes the vision of the upper class, the imperialistic view, and the masculine and voyeuristic gaze. In addition, spatial political economists have paid attention to the economic aspects of landscape. They have emphasized that the material production of landscape is indispensable in the production of surplus values in the capitalistic system. Thus, we insist focusing dialectically on both the materiality and ideology of landscape.
