  • In the present study, the influence of operating conditions on fuel economy for hybrid electric vehicle was analyzed. In order to accomplish this, vehicle speed, engine speed, battery current and voltage, SOC (state of charge),motor speed and torque, generator speed and torque, engine coolant temperature etc. were measured in real time. The tests were carried out under different driving cycles which are urban and highway cycles, KOREA CITY cycle and on-road driving, and also under various operating conditions such as different initial SOC, with or without regenerative braking etc.. Generally, conventional gasoline engines show a poor fuel economy at stop and go driving, because braking energy is wasted and the engine is operated in low thermal efficiency regions. However, in case of hybrid vehicles, higher fuel economy can be obtained because of utilizing the maximum thermal efficiency regions of engine, idling stop of engine, and regenerative braking etc..

  • Activation of conventional market in small town is important in the reinvigoration of local economy as an economical center. The revitalization of local economy is closely related to the fosterage of conventional market. So the local government is trying to activate the market. However, the projects for the activation of conventional market are mostly centered on the modernization of facilities which is carried out at urban districts. Those facilities-centered plans, being carried out at urban district, lack the consideration of the peculiarities of rural districts and the regional conditions of the conventional market in small towns. And some projects for the modernization of facilities produce negative results. Especially the conventional market in small town shows a spatial structure of a five-day market and a market place and it was influenced by the spatial relationship between the permanent market and periodic market. So analyses on the spatial lay-out and form, store facilities, spatial distribution of types of business, spatial utilization on market place are needed to improve the physical environment of the conventional market. In this context, the study analyzed systematically the space of an old and lagged Hongseong conventional market located in central district of a small town. And It is expected that the results use as a basic data to establish effective space improvement plan for conventional market in small town.

  • During the past three decades, there have been drastic changes in many fields in Korea. Social and economic changes which occurred meantime have influenced clothing expenditures of Korean consumers. The purpose of this study was to investigate the change of clothing expenditures and its determinants in Korea during the period of 1965 to 1993. In particular, the impacts of income and price on clothing expenditures were examined using data from the National Acccounts published by the Bank of Korea as well as Urban Household Economy Survey published by the Bureau of National Statistics. Per-person consumption expenditures for clothing and shoes (CSX) in permanent price generally increased in accordance with the increase of income since 1965. From 1978 to 1984, however, there was a slight decrease in clothing expenditures in spite of the continuous increase in income, due to the depression of national economy. The proportion of CSX in total consumer spendings has decreased continuously since 1978. In recent years, CSX take only 5% of national aggregate consumption expenditures, while consumption expenditures of urban consumers is 8%. The expenditures for traditional clothing and fabrics for home- sewing decreased most. The results of this study should provide a broader view of the pattern of clothing consumption by Korean consumers. Moreover, the findings can suggest how social and economic changes of a society affect consumers' clothing expenditures.

  • This study is basically to investigate the possibility of revitalizing the fishing village economy by targeting on trip type, propensity, and awareness of visitors who visited Gogunsan in JeonBuk by applying Blue Amenity. As the result of survey, it showed that visitors in Gosunsan islands generally were satisfied with trip, and they had considerably higher intention of revisit. However, it showed that the improvement and publicity of various travel services including resources and facilities were demanded. In particular, it should pay attention to requirements depending on age and selection of main visitors with reference to revisit, and as the result, the factors having the most important influence on are traffic, and natural scenery, so it is considered that these factors must be maintained to increase the rate of revisit with full of concentration. Besides, it is confirmed that Visitors are unfamiliar with Blue Amenity applying fishing village's own historical cultural resources with reference to preferring islands trip, and they were much concerned about the establishment of tentatively named "regional(urban - fishing village) center" to revitalize the fishing village economy. Moreover it could grasp the tourist industry operated jointly by fishing villages, the pride of town to characterize, advantage in promoting the tourist industry as compared with other regions, and difficulties or recommendations in promoting the tourist industry. And comprehensive investigation of Blue Amenity resources in this region and the measures of improving life environment must be performed in future.

  • In this article, we look at the application of BIM (Building Information Modeling) in sustainable infrastructures. In response to global warming, energy shortages, and environmental degradation, people are trying to build eco-friendly, low-carbon cities and promote eco-friendly homes. A "green" building is the entire life cycle of a building that includes maximizing the conservation of resources (energy, water, land, and materials), protecting the environment, reducing pollution, providing people with healthy, comfortable, and efficient use of space, and establishing harmony between nature and architecture. In the field of ecological and sustainable buildings, BIM modeling can be integrated into buildings with analog energy, air flow analysis, and solar building ecosystems. Using BIM technologies, you can reduce the amount of waste and improve the quality of construction. These technologies create "visualization" of digital building models through multidimensional digital design solutions that provide" modeling and analysis "of Scientific Collaboration Platforms for designers, architects, utility engineers, developers, and even end users. Moreover, BIM helps them use three-dimensional digital models in project design and construction and operational management.

  • 본 연구는 "도시재생 활성화 및 지원에 관한 특별법(이하 도시재생특별법)"에 의한 도시재생사업에서 공공시행자의 역할을 모색하기 위하여 일본의 도시재생사업을 분석하여 국내에의 시사점을 도출하고자 하는 연구이다. '도시재생법'에서는 공공의 역할이 강조되고 있으나 도시재생활성화계획 수립 이후 사업시행단계에서의 공공의 역할에 대한 언급되지 않고 있어 향후 도시재생사업을 수행함에 있어서 일본 사례를 구체적으로 고찰해보는 것은 중요한 의의가 있는 것으로 판단된다. 구체적으로 일본 도시재생사업에서 공공시행자의 역할을 수행하고 있는 도시재생기구(UR)가 수행한 도쿄의 오오테마치 1-1지구, 시노노메 지구, 시부야역 가구, 오시아게 나리히라바시 4개 지구에 대한 심층 사례분석을 실시하였다. 사업수행체계에서 각 주체가 어떠한 역할을 담당하는지를 고찰해봄으로써 도시재생사업의 성공적인 수행을 위한 공공시행자의 역할을 제시하고자 하였다.

  • This study has investigated the degree of similarities and/or differences of consumption expenditure styles among the households with different occupation. Two types of analysis were performed. One was comparative analysis which used to identify the changes of consumption expenditure styles among different occupation classes using time-series data of 1977-1996 Korean Urban Household Expenditure Survey and Rural Household Economy Survey. The other was multivariate analysis to investigate the effects of occupation on consumption expenditure styles with 1551 sample household data from 1996 Korean Urban Household Expenditure Survey. The results showed that the differences in consumption styles among different occupation classes including farmers are diminished during last two decades while there still exist some degree of differences in consumption styles. After controlling other socio-economic factors it is found that occupation is a determinant of consumption patterns of urban w ge earners especially consumption for clothing and health items.

  • With recent growth of population and industry, urban development grows into grand scheme of excavation and construction in urban area. As the development progress advanced, the developments get large and deepen. With a progress of technology development in geotechnical engineering in Korea, most our grand scheme of projects follows great progress. On the other hand, some excavation in construction site caused direct or indirect event that affects the adjacent or surrounding structures by excavation from time to time. This event usually happens around residential and commercial area where underground tunnel, subway station, commercial building, and high-rises excavation site is, could lead great damage on economy as well as personal injury or human casualties. In order to prevent this event, the study has to be done with analysis on various events of excavation and its cause. In this paper, the research has collected the various excavation events and their causes to analyze on each site and event to define emphasis on surrounding environment.

  • Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, based on the Japanese Urban fire simulation to target the traditional market area and suitability of fire risk assessment were reviewed.
