엔터프라이즈 정보화를 추진하는데 있어서 가장 심각한 문제 중 하나는 서로 연계 통합되지 않은 사일로(Silo) 시스템 문제이다. 정보전략계획(Information Strategy Planning)은 비즈니스에 필요한 개별시스템 기능성 도출에 국한되어 오히려 이러한 사일로 문제를 가중시키고 있다. 본 연구는 엔터프라이즈 사일로 문제가 엔터프라이즈 제반 요소들이 가지는 관계에 대한 총체적 시각, 곧 '아키텍처적 시각'이 부재하기 때문이라고 보고, 이러한 엔터프라이즈 요소간 관계를 정의하고 체계화할 수 있는 '엔터프라이즈 아키텍처 지향 모델'을 제안한다. 이를 위해 본 연구는 엔터프라이즈 제반 구성요소들 상호간에 수직적, 수평적 관계성을 부여하고 엔터프라이즈가 이들 관계에 있어서 거치는 진화의 단계를 설정한다. 엔터프라이즈 아키텍처 지향 모델에서 수직적 관계는 Kaplan과 Norton의 연구로부터 도출된 성과, 역량, 전략이라는 세 요소가 조직 상하간에 전략적 관리적 측면에서 '연계(Alignment)'되어야 함을 의미한다. 수평적 관계는 Ross 등이 통합 대상으로 다룬 정보기술, 데이터/프로세스, 비즈니스 컴포넌트 요소들이 수평 조직간에 기능적 실행적 측면에서 '통합(Integration)'되어야 함을 강조한다. 본 모델은 엔터프라이즈의 현재와 미래 아키텍처를 사상하는 개념공간으로서 엔터프라이즈의 현재 모습을 파악하고 엔터프라이즈가 지향하는 미래 모습을 도출하며 현재에서 미래로의 이행을 인도하는 개념적 틀로서 작용하게 된다. 끝으로 본 모델의 적용 사례를 들고 모델의 적용이 각 엔터프라이즈가 지향하는 엔터프라이즈 모습에 따라 어떻게 달라질 수 있는지를 논의한다.

본 연구는 국내 1인 가구수가 증가함에 따라 중소규모 공동주택에 대한 정책적 관심이 높아지는 가운데, 해당 사업 유형의 사업주들이 대비하기 가장 어려운 리스크로 건축심의가 지적되고 있다. 본 연구는 B도시의 25개 중소규모 공동주택 프로젝트에 대해 다차원 분석방법을 적용하여 건축심의 의견의 경향과 비정형데이터로서 건축심의 의견의 특성을 분석하였다. 대응분석 및 MDS 분석을 실시한 결과, 선행연구와 동일하게 B도시의 건축심의 의견은 주로 상위분류에서 '구조'와 '계획'에 관련된 키워드가 주를 이루었다. 즉, 모든 키워드의 출현빈도수 대비 각 상위분류의 빈도수의 합은, 선행연구의 직접분류결과는 '구조' 40%, '계획' 27%이며, 본 연구의 분석결과는 '구조' 44%, '계획' 39%인 것으로 나타났다. MDS모델의 적합도는 34.4%로 비교적 낮은 편이나, 대응분석을 통해 확인한 결과 건축심의의 비정형적 자료의 특성에 기인한 것으로 확인하였다. 또한, 본 연구에서 분석한 건축심의 의견과 같은 비정형적 데이터는 심의위원의 주관과 지자체별 양식에 따라 다양한 데이터의 조합과 출현이 이루어지며, 주로 언급되는 단어와 전혀 다른 키워드가 등장할 수 있어 첨도가 낮고 왜도가 높은 확률분포적 특성을 파악할 수 있었다. 본 연구는 일부 한계점이 있으나, 비정형 데이터로서 건축심의 의견의 특징을 도출해내었으며 추후 세부분석을 위한 기초 연구로서 활용 될 수 있을 것이다.

Bong-amsa Temple is a special temple in the custody of Jogye sect, a branch of Buddhism in Korea. Due to limited public access to this temple, its Geungnakjeon(paradise shrine) has been little known to outside. But it is known that the Geungnakjeon has been not yet explored from academic standpoints in terms of its historical establishment as well as applications, and it would be two-storied wooden pagoda or the like. In order to examine its historical establishment, this study investigated historical records related to Bong-amsa Temple and its intrinsic architectural style. As a result, it was estimated that the building was established around the transitional period ranging from the late Koryo dynasty to the early Joseon dynasty. And it was found that the Geungnakjeon is not the two-storied wooden pagoda, but the unique building including an incidental component called Chayanggan(遮陽間; a sort of stepped penthouse) in Korea. In order to examine its possible applications, this study compared this building with other Buddhist funeral articles in forms similar thereto, such as Buddhist pagoda(僧塔), sarira container(舍利器) and Gamnodo(甘露圖) which depicts Byeoknyeon Daeban(碧蓮臺畔; a palanquin carrying malignant spirit). Then, this study estimated its possible applications on the basis of relevant historical literatures. As a result, it was found that this building was used as Wondang(願堂; a sort of Buddhist prayer house) to wish royal family's going to Nirvana after death, and it was not Confucian-style architecture popularized in the era of Joseon dynasty, but Buddhist-style architecture built widely from the era of Koryo dynasty to the early Joseon dynasty.

This study based on the hypothesis which the spatial qualities in the Mies's early works are not extinct but potentially immanent in his latter works. In Mies's early works, destruction of outline, centrifugal extension of fluid space, and asymmetry are distinctly showed. These qualities probably revert to the indefiniteness of space. In Mies's latter works, however, these dynamic qualities are disappeared. Geometrically precise outline and exact grid structure represent universal space derived from zero-degree pure box. These qualities probably revert to tile definiteness of space, characterized by the unmovable emptiness. Although Mies works vary in external form, his expression technique of space reveals continually both the qualify of definitive and indefinitive space. For example, in the Museum for a Small City(1942) unbuilt project. elements defined by the perspective are fixed and static, but elements defined by the collages are floated and dynamic. The former reigns over the realized buildings of Mies, while the latter seems to be latent in terms of Schein which transcends reality. If we can penetrate this point, it's possible to read the other side of Mies' architectural works, distinct from both the canonized interpretation and the excessive criticism. Point is that later works of Mies must be understood as interplay of universal space appeared as phenomenon and flowing elements latent in. Architectural space of Mies keeps a distance with actual space through latent manner of being while preserves the empirical actuality It provides us with an occasion which appears only in an instant, in which even the ordinary things reveal its poetics.

A typology study is a comparative study of the physical characteristics of the built environment divided into distinct types such as architecture, culture, and environment. Lao vernacular dwellings were initially created based on the Lao people's behavior in terms of beliefs, traditional culture, lifestyle, and local wisdom with regard to the environment, climate, geography, and materials. The main research method used in this study is a comparative case study of three ethnic dwellings. The multiple data collection tools employed included second source data and primary data to analyze the findings of the unique characteristic typology of Lao vernacular dwellings. The objective of this paper is to compare the cultural and physical contexts, the patterns and origins of settlement, the architecture, the cultures, and the local indigenous knowledge related to the dwellings and settlement of the three main ethnic groups. These three groups are rich in tradition and their documentation is therefore essential for the intellectual history of the society of Lao; this research could therefore aid in enhancing our understanding of the three typologies of Lao vernacular architecture and settlement within the historical and sociocultural contexts of each ethnicity to convey an understanding of Lao vernacular dwellings by analyzing their different types to help identify the differences and similarities among architectural artifacts by recognizing the invisible connections between them, whereby the figurative ornamentation is based on the relationship between man and nature. This study also provides a glimpse of the living culture and characteristic features of Lao vernacular architecture.

The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.

The purpose of this study was to evaluate the variation in building energy predictions caused by simulation settings related to building envelop thickness. The study assessed the ceiling depth impact on skylight energy performance through OpenStudio integrated Radiance and EnergyPlus simulation programs. A ceiling as deep as 1.5 to 3m was analyzed for skylight to roof ratios from 1% to 25%. The results indicated that the building ceiling depth negatively affected the capability of skylights to significantly reduce building energy consumption. Through a parametric analysis, the study concluded that 8%, 9%, 10% and 11% skylight to roof ratio were optimal in terms of total building energy consumption for a ceiling depth of 1.5m, 2m, 2.5m and 3m, respectively. In addition, the results showed that the usually recommended 5% skylight to roof ratio was only efficient when no ceiling depth was included in the simulation model. Furthermore, the study indicated that the building energy saved by the optimal skylight of each ceiling depth decreased as the ceiling depth deepened. The highest total building energy reduction was 9%, 7%, 5% and 3% for a ceiling depth of 1.5m, 2m, 2.5m and 3m, respectively. This study induced that the solar heat gains and daylight visible transmittance by ceiling depth were crucial in the predictions of skylight energy performance and should not be neglected through building simulation simplifications as it is commonly done in most simulation programs' settings.

Since the massive power outages that hit across the nation in September 2011, a growing imbalance between energy supply and demand has led to a severe backup power shortage. To overcome the energy crisis which is annually repeated, a policy change for deriving energy supply from renewable energy sources and a demand reduction strategy has become essential. Buildings account for 18% of total energy consumption and have great potential for energy efficiency improvements; it is an area considered to be a highly effective target for reducing energy demand by improving buildings' energy efficiency. In this regard, retrofitting buildings to promoting environmental conservation and energy reduction through the reuse of existing buildings can be very effective and essential for reducing maintenance costs and increasing economic output through energy savings. In this study, we compared the energy reduction efficiency of national power energy consumption by unit production volume based on thermal power generation, renewable energy power generation, and initial and operating costs for a building retrofit. The unit production was found to be 13,181GWh/trillion won for bituminous coal-fired power generation, and 5,395GWh/trillion won for LNG power generation, implying that LNG power generation seemed to be disadvantageous in terms of unit production compared to bituminous coal-fired power generation, which was attributable to a difference in unit production price. The unit production from green retrofitting increased to 38,121GWh/trillion won due to the reduced energy consumption and benefits of greenhouse gas reduction costs. Renewable energy producing no greenhouse gas emissions during power generation and showed the highest unit production of 75,638GWh/trillion won, about 5.74 times more effective than bituminous coal-fired power generation.
