There was a dire need to compile data about energy consumption data by use to analyze residential energy consumption patterns relating to changes in lifestyles, or changes in life behavior. Accordingly, bottom-up model for residential energy consumption by residential use was developed by life behavior classification in an attempt to analyze energy consumption. This paper multiplied each appliance's running times by each appliance by life behavior and built a residential bottoms-up model to figure out the energy consumption of each household. The uses by life behavior were broken down into lighting, heating, cooling, entertainment, obtaining information, hygiene, and cooking.

The purpose of this study is to investigate tendencies on land use in the housing site development district by grasping the characteristics of changes of building use at the borders of single-detached housing area for planning single-detached housing area in the future. It is divided the borders of detached housing areas into three types, educational facility, parks and green spaces, and apartment complex, and then analyzed the characteristics of each location after a field study. It is summarized as follows. First, there were stationery and flour-based meal stores in adjacent borders near educational facilities, suitable for students' interest and motion patterns, and it is required to consider about frequent children's action in the street. Second, there are many facilities for park users and residents, such as educational institutes and restaurants in adjacent to borders near parks. In borders neighboring buffer green belt areas, warehouses and vacant sites were mainly distributed. And the revitalization of streets was lower than others, because a road was used as a parking space. Third, there were realty dealers, food stores, and laundries which provide the dwellers with service in adjacent borders near multi-family housing.

This used a new method to capture the neighbouring relationship among parcels. To define the neighbouring relationship, all the surrounding parcels in the study area can be identified as neighbours of the current parcel as long as they touch each other even at a point. To examine neighbouring parcels on all polygons of the study area, this study used ArcViews avenue programming which visited each polygon in turn and produced an outfile containing the parcel record ID and the contents of each of the adjacent parcels. The second thing is to translate the record IDs of neighbouring parcels into land use. For this, this study used the Lookup function in Excel to obtain neighbouring land use. To deal with how to calculate the ratio of each land use to neighbouring land uses, this study used Visual Basic. finally, this study considered a term of neighbour land use as the ratio of the number of urban use adjacent parcels to the total number of adjacent parcels. This study shows that GIS and spatial analysis can be applied to land use change in the urban fringe area at a very detailed level using municipal parcel data which occupies about 80% of administrative affairs, especially at the local government level in Korea. The results of analysis can be useful for local government to understand its situation and to manage land use efficiently in the urban fringe. The methodology developed in this study is especially useful for an empirical approach.

모직물은 소모사의 구조(번수, 연수), 원료의 특성과 직물소재용도에 따른 직물설계 조건이 다양하게 변화 할 수 있기 때문에 이론적으로 실제현장에서의 의류용도에 따라서 적용할 수 있는 배경$^{1}$)이 확립되어 있다. 그러나 합섬직물의 경우 모직물에 비해 직물설계가 단순한 면이 있음에도 불구하고 합섬직물 종류와 의류의 용도에 따른 현업에 적용 가능한 직물설계조건의 이론적 배경 확립이 미흡한 수준이다. (중략)

최근 스마트 기기의 발전 및 보급 확대에 따라 사용자의 범위는 계속해서 증가하고 있다. 이에 따라 모바일 쇼핑 이용자들이 지속적으로 늘고 있고, 광고 또한 인터넷 기반에서 모바일 플랫폼 기반으로 변화하고 있는 추세이다. 모바일 기기의 중요성이 커지고 편의성이 증대되면서 소비자들의 구매방법에도 많은 변화가 일어나고 있는데, 정보를 탐색하고, 구매를 결정하고, 결제하는 행위 등 모바일에서 이루어지는 비중이 늘어나면서 앱을 구성하는 것 또한 중요한 마케팅 전략으로 자리잡고 있다. 본 연구의 목적 역시 사용량이 급증하게 된 모바일 쇼핑에서 SNS활용도의 조절효과를 중심으로 하여 광고 유형과 애플리케이션 특성이 소비자들의 구매의도에 미치는 영향에 대해서 살펴보고 결과를 제시하여 관련 업계에 도움을 주고자 한다. 본 연구에서는 모바일 쇼핑 이용자들의 모바일 쇼핑을 통한 구매의도에 미치는 영향 요인을 파악하기 위한 선행연구와 이론적 배경을 통해 모바일 광고유형, 앱 특성에 관한 고찰과 구매의도와의 인과관계를 살펴보았다. 연구의 목적은 모바일 쇼핑 이용자들의 모바일 쇼핑을 통한 구매의도에 미치는 영향 요인을 파악하고, 변수들 간의 관계를 규명하는데 있다. 구매의도에 영향을 미치는 요인을 광고 유형, 앱 특성으로 구분하고 이들 변수들이 구매의도에 미치는 영향력을 조절하는 변수로 SNS활용도를 도입하였다.

A local government is not a group under central government, rather it fulfills the function independently as a economic social administrative unit. Belief and role of chief of regional government, and citizen's understanding and interest regarding importance of an election pledge are getting higher. Thus, this study researches election pledges which can be a main variable of urban plan. Especially, the study attempts to analyze impacts of election pledge on urban spatial structure and regional economic structure. When relationship between election pledge and Use Zoninig change were analyzed, the result showed that development related entire use Use Zoninig changes were related with election pledge. When it was subdivided according to each use area, relationship of use area change among election pledge and urban spatial structure found to have relatively high in resident area. In addition, relationship between population factor and election pledge was high. This can be judged as election pledge and urban spatial structure change have relationship. Particularly, sectors related with residents are expected to have high correlation. As a result, pledges regarding general welfare administrative part were a few at areas with many pledges regarding regional economic development. So, it can be classified as regional economic development oriented pledge suggesting area and welfare administrative oriented suggesting area. Through realization of these pledges, it might be able to affect urban spatial structure changes.

최근 중소규모 하천은 하천수 및 하천변 지하수 이용의 증가와 토지이용변화 등 유역 내 수문인자의 특성 변화로 인해 하천의 건천화가 점증하고 있어 하천 환경이 악화되고 있는 실정이다. 본 연구에서는 격자기반의 분포형 장기수문 모델(PGA-CC)을 이용하여 과거 수십년동안 토지이용변화에 따른 하천 건천화 영향을 평가하였다. 실제 건천화가 진행되고 있는 삽교천 상류유역($358.8km^2$)을 선정하였고 토지이용변화분석을 위해 과거 1975년 토지이용도(Past), 현재 2008년 토지이용도(Present)를 구축하였다. 각각의 토지이용 항목 중 변화율이 가장 높은 도시비율은 과거 토지이용도에서는 2.6 %였으며 현재 토지이용도에서는 11.3 %로 8.7 %가 증가하였다. 모델 검보정은 최근 7년(2005-2011)동안 최종유역출구지점에서 유출 검보정을 실시하였다. 그 결과 NSE (Nash-Sutcliffe model efficiency)은 평균 0.71로 유출량의 모의값과 실측값이 유효한 것으로 나타났다. 건천화를 평가하기 위해 시험유역에서의 5 WPs (Watching Points)를 선정하여 과거 및 현재 토지이용조건을 모의하고 유황분석을 통한 갈수 변화량 분석을 실시하였다. 건천화 빈도분석을 위해 GEV (Generalized Extreme Value) 갈수빈도분석을 실시하여 과거 토지이용 모의결과 산정된 평균 갈수량($m^3/s$) 이하로 낮아지는 유출량 일수를 계산하였다. 최종유역출구에서 과거 및 현재 토지이용도에서 모의된 평균갈수량은 각각 $3.27m^3/s$ 및 $3.11m^3/s$로 나타났다. GEV 갈수빈도분석결과 과거 토지이용조건에서의 평균갈수량은 $3.20m^3/s$(재현기간 2.33년)으로 나타났다. 도시증가에 따른 인구증가는 지하수 사용량에 증가를 가져온다. 이는, 건천화에 영향을 미치며 본 연구에서는 지하수이용량 자료(1998-2011)를 이용하여 도시면적과 지하수이용량의 선형회귀분석을 실시하여 과거 22년 지하수 사용량을 예측하였다. 그 결과 지하수사용량 증가는 토지이용변화와 복합적으로 상류유역에 하천의 변화를 가속시키는 것으로 나타냈다.

In recent years, the risks and uncertainties associated with mixed used development in urban regeneration projects which have actively been implemented at home and abroad have been on the rise due to the uncertainties of the initial business plan, difficulty of financing, increase in total cost and schedule delay. To cope with rapid social and economic changes and optimize benefits, a risk-based configuration management process that considers life cycle is required, along with accurate planning in the early stage of the business. In addition, it is necessary to prepare measures that can respond to the evaluation and measurement of the configuration factors in relation to the business process. However, the focus of previous studies on configuration management in the field of construction was mainly on humanities and the sociological aspects such as organization, leadership, ideology and similar concepts. There has been limited research on the process and measurement and evaluation methods for configuration factors required in decision-making on the risks and changes that can occur in the actual project implementation phase. Accordingly, in this study, we defined risk-based configuration factors and developed a process and MECA/3DAM/CII methodology to measure and evaluate these factors so as to carry out systematic configuration management of mixed used development in urban regeneration projects.

The information technology is becoming very essential in our daily lives. Internet environment, especially, has been seriously affecting the area of education. The cost-effectiveness analysis is required as universities are investing quite much in the development of internet infrastructure. This study shows a simple statistical result on the utilization of internet equipments. It is found that the enough availability is not provided to the students who are going to use equipments for the purpose of study as a big portion of them are occupied by the users for the purpose of amusement.
