Since 1997, Dr. Shin-ya Nishimura has been developing an actual town planning project named the "Gangi Project". Students, inhabitants and local professionals walk around Omotemachi, examine the characteristics of the environment and the inhabitants' way of life, discuss plans and designs for traditional wooden arcades called locally "gangi". Students and inhabitants build the gangi together every year. The purpose of this study is to clarify how an experimental project aiming to preserve a living environment obtains sustainability as an actual town planning exercise. The research hypothesizes that sustainable town planning should include strategies for financial autonomy, active participation of inhabitants, supports from local professionals, an acceptance of changing environments, and responsible construction. The project has been carried out as a part of actual town planning, and continues to create a daily living environment based on the recent economical and industrial situation of the town. By focusing on the influences of the project on the town and inhabitants, the study has revealed the possibility of an actual town planning with small budget, and importance of a collaborative relationship with various participants in order to foster a sense of responsibility regarding the construction. The project also highlights the implication that sustainable town planning creates not only a participatory system but also a collaborative one in which participants take responsibility for the issues involved in the construction process.

The purpose of this study was to set and analyze the utilization of the substituted agricultural land in the Dongtan new town in Hwa-seong city. The results of this study were as follows. In the respect of the land efficiency and utilization, the need of the agricultural land in the Dongtan has shrunk. Therefore, the land should be reconsidered and developed as other purposes. The land could be developed as the weekend farm for the city people. The weekend farm is currently gaining popularity because the citizens want to not only experience the nature but also get a healthy food. So, the land in the new town could provide them with a good place. And the Han-ok(Traditional Korean style housing) is recently in the limelight of many people because of its healthy function and the special aesthetic, so the agricultural land of Dongtan could be a great opportunity to develop the Han-ok village. Lastly, the logistics center for agricultural products could be proposed. Because the traffic condition of the new town is satisfactory, the land is idealistic as the logistics center which connect the capital with the local. These practical uses of agricultural land in the Dongtan new town will be able to provide opportunities to improve the quality of life in the area and develop the land more efficiently.

This paper reports the results of a study designed to understand and facilitate disaster mitigation for communities located in low frequency/high magnitude earthquake zones. The study is based on a small town located near the New Madrid Fault Zone and is therefore at significant earthquake risk. A system dynamics model describes the variables and policies governing the distribution of building safety over time. Data from this town is used to establish a 25-year baseline. Simulations are run to demonstrate the consequences of different building policies.

In order to make comparative analysis of geomorphological changes caused by urban development, I surveyed the distribution of geomorphological resources of 'Daegu Innovation Town' development plan area. The results are as follow: (1) At the front of small valleys of back-mountains are formed small alluvial fans, and at the side of small valleys are distributed hills connected with back-mountains. (2) As small valley erode laterally hills, vertical bluffs and planner bedrock riverbed are formed, and in some riverbed are appeared mud cracks and ripple marks. (3) The depth of valley in alluvial fan of 'Sinseo District' is 7m. In Sinseocheon valley dissecting alluvial fan, fluvial terraces 2m high above riverbed are distributed. Those terraces were formed while alluvial fan was dissected after last glacial period.

Most local agencies such as counties and small cities continuously express difficulties in making technically and financially defensible decisions on their pavement infrastructure maintenance and rehabilitation. Unlike pavement systems managed by state highway agencies, the total lane-miles of many local pavements are significantly short and they are managed by a limited number of staff who typically have multiple responsibilities. Most local agencies also do not have historical pavement performance data and the lack of a systematic decision making framework exacerbates the problem. A structured framework and an easily accessible decision support tool that reflects their local requirements, practices and operational conditions would greatly assist them in making consistent and defensible decisions. This study fills this gap by developing a systematic pavement treatment selection framework and a spreadsheet based tool for local agencies. It is expected that the proposed framework will significantly help local agencies to improve their pavement asset management practices at the project level.

The explicit formulation of the J-integral and the M-integral is constructed in terms of the stress intensity factor and the higher order stress coefficients for Mode II cracks under small or large scale yielding. Furthermore, the stress intensity factor and the higher order stress coefficients as well are computed with the aid of the two-state J- and the M-integral, which is found to be accurate and efficient. It is found that the contribution from the higher order singularities to the J-integral is closely related to the configuration of the plastic zone.

Precast-cast insitu concrete bridge construction is widely practiced for small to medium span structures. These bridges consist of precast pre-stressed concrete beams of various cross-sections with a cast in-situ reinforced concrete slab. The connection between the beams and the slab is via shear links often included during the manufacturing process of the beams. This form of construction is attractive as it provides for standardisation, reduced formwork and construction time. The assessment of the integrity of shear connectors in existing bridges is a major challenge. A procedure for assessment of shear connectors based on vibration testing and finite element model updating is proposed. The technique is applied successfully to a scaled model bridge model and an existing bridge structure.

Traditional markets located in local small towns have effected local economies and culture for a long time, but their current situation is not so good. In this context, this paper tries to find out the physical characteristics and problems of local traditional markets and to extract some suggestions to improve them. For this, I selected three traditional markets as case study areas such as Mugeuk, Samseong, and Boeun located in local small town in Chungbuk Province. Using the diverse survey methods including theoretical review, basic data analysis, field survey, and questionnaire study, I examined physical features such as location, spatial structure, type of business, streetscape, and convenient facilities in the designated markets. Finally, based on this, I proposed some suggestions on the improvement of traditional markets located in local small towns as followings; expand and improve the convenient facilities, enforce the image of entrance, boost and form groups of specified business, reflect the local characteristics, and amend the related institution etc.

The purpose of this study was to identify what factors are associated with marital satisfaction of the foreign wives who live in small town. Data for the study were based on a snowball sampling of 101 foreign wives who married to Korean husbands and had residence in Changwon and Masan city, Gyeongnam, Korea. The respondents reported higher levels of marital satisfaction and lower levels of marital hardship. To identify the variables affecting marital satisfaction, a regression analysis was conducted. Independent variables included age difference, educational difference, monthly income, conformity of information about husband, marital hardship, relationship with parents-in-law and taking class with husband. While conformity of information about husband, marital hardship and taking class with husband had strong effects on marital satisfaction of the foreign wives, age difference, educational difference, monthly income and relationship with parents-in-law didn't show the significant effects on the marital satisfaction of the foreign wives.

Since Paris Climate Change Conference in 2015, many policies to reduce the emission of greenhouse gas have been accelerating, which are mainly related to renewable energy resources and micro-grid. Presently, the technology development and demonstration projects are mostly focused on diversifying the power resources by adding wind turbine, photo-voltaic and battery storage system in the island-type small micro-grid. It is expected that the large-scaled micro-grid projects based on the regional district and town/complex city, e.g. the block type micro-grid project in Daegu national industrial complex will proceed in the near future. In this case, the economic cost or the carbon emission can be optimized by the efficient operation of energy mix and the appropriate construction of electric and heat supplying facilities such as cogeneration, renewable energy resources, BESS, thermal storage and the existing heat and electricity supplying networks. However, when planning a large residential town or city, the concrete plan of the energy infrastructure has not been established until the construction plan stage and provided by the individual energy suppliers of water, heat, electricity and gas. So, it is difficult to build the efficient energy portfolio considering the characteristics of town or city. This paper introduces an energy mix optimization(EMO) method to determine the optimal capacity of thermal and electric resources which can be applied in the design stage of the real large-scaled residential town or city, and examines the feasibility of the proposed method by applying the real heat and electricity demand data of large-scale residential towns with thousands of households and by comparing the result of HOMER simulation developed by National Renewable Energy Laboratory(NREL).
