우리나라에 공공도서관이 많이 없다. 그 이유는 국민들의 공공도서관에 대한 중요성 및 필요성에 대한 인식 부족과 중앙 및 지방정부의 도서관건립에 대한 인색한 투자와 함께 효과적인 공공도서관 건립정책이 없었기 때문이다. 이제 선진국과 같은 작은 도서관 건립 및 운영 정책을 펴야 한다. 지역 재개발 및 아파트 재건축 추진은 이들 지역에 작은 규모의 마을도서관을 건립할 수 있는 좋은 기회이다. 서울에 있는 J아파트는 재건축을 추진하고 있는데, 이 시점에서 새로운 위치로 옮겨가는 동사무소와 우체국을 하나의 건물로 신축하고, 이 건물 내에 공공도서관을 설치할 수 있을 것이다. 도서관을 이들 시설들과 함께 1층에 배치한다면 시너지 효과를 발생시켜 세 기관 모두에게 도움이 될 것이다. 이처럼 재개발 및 재건축 지역에 공공기관 혹은 상엽시설과 함께 복합건물 형태로 작은 도서관을 건립하는 것은 우리나라 공공도서관의 부족 문제를 해결 할 수 있는 좋은 방법이다.

Open Housing System ideas were developed in Korea in the 1980s to satisfy the demand for variety indwelling spaces. This domestic attempt to apply open building principles was highly restricted and was applied only in support of middle-large size apartments rather than small size apartments. One of the problems was the conventional design of building structures. It was difficult to effectively satisfy the various lifestyles and transformation of dwellings because existing apartments were designed using a concrete wall structure approach, in which room sizes and arrangements were fixed by the placement of structural concrete walls. This was the result not only of structural analysis (other structural designs were possible) but also the result of the idea that the standard plan was suitable for a stable society and was easier to implement, and that change in social standards and technical upgrading was not going to happen. This study presents an apartment concept in which open building design methods were applied to satisfy the problem of various lifestyles and household sizes and preferences for small apartments. This concept also helps to create a more effective and long lasting building which decreases construction waste, saves resources and protects the environment by enabling the building to accommodate combining, increasing / decreasing, changing location or changing usage of rooms.

This study is intended to investigate an influence of the kinds and the maximum size of aggregate on the compressive strength of small size core specimen. According to the results, the compressive strength of standard specimen is large in order of basalt, granite and limestone aggregate, and shows increasing tendency as the maximum size of aggregate grows large. The compressive strength of concrete using basalt aggregate shows similar tendency to granite aggregate, and that of concrete using limestone aggregate decreases slightly, compared with granite aggregate. The reducing ratio of the compressive strength of 25mm core specimen is least when the maximum size of aggregate is 10mm. But the compressive strength of 50 and 100mm core specimen is almost not influenced by the maximum size of aggregate.

Fast delivery of construction projects provides more value to project owners. Batch production, which is production not in single pieces, but in batches, is a common approach in repetitive construction projects such as multi-unit residential building construction projects. In batch production, the use of a small batch size allows the early start of subsequent activities, and thus can lead to early completion of projects. In addition to batch size, balance between productivities in construction activities can affect project duration. However, the impact of the balance between productivities with regard to their order on project duration has not been studied. The main goal of this study is to test a hypothesis, which is that the order of construction activities' unbalanced productivities affects the amount of time reduction that can be achieved by using a small batch size. A computer-based simulation model was developed, and five different cases were simulated to test the hypothesis. The conclusion of the simulation result is that the order of productivities does not affect the time reduction achieved by using a small batch size. It is expected that the findings of this study can help general contractors make decisions in terms of batch size.

Piloti-type building is one of typical vertical atypical buildings. These buildings can fail by weak-story or flexible-story mechanism on the first story. They should be designed by taking into account the special seismic load, but those less than six stories are not required to confirm the seismic performance from structural engineers in Korea. For this reason, small-size pilloti-type RC buildings need to be checked for seismic performance. Based on this background, this study performed nonlinear dynamic analysis using the PERFORM-3D for small-size pilloti-type RC buildings and assessed their seismic performance. Examples are two through four story buildings with and without walls in the first story. The walls and columns in the first story satisfied the target performance in the basic of flexural behavior due to quite a large size and reinforcement. However, wall shear demands exceed shear strength in some buildings. When designed for KBC2009, wall shear strength exceed shear demand in some buildings, but still does not in others. Consequently, wall shear must be carefully checked in both existing and new small-size pilloti-type RC buildings.

대규모 도서관을 몇 개 건립하는 것보다 소규모 도서관을 많이 건립하는 것이 단기간에 공공도서관 인프라를 확충하는 데 효율적이다. 우리나라의 공공도서관은 선진국들과 비교해서 큰 규모로 건립되었다. 본 연구는 우리나라 공공도서관의 대부분이 중 대규모로 건립된 원인을 분석하고자 하였다. 이를 위해 2011년 12월 기준 우리나라 전체 791개 공공도서관의 연면적을 조사하였다. 우리나라 공공도서관의 평균 연면적은 $2,495m^2$로 나타났다. 본 연구는 도서관의 규모 측면에서 공공도서관의 효율적인 인프라 확충을 위해 고려해야할 도서관 건립 정책은 무엇인지를 파악하고자 하였다.

Our country is aiming at 30% reductions in building energy consumption accounting for 39% of the total energy consumption by 2020[1]. For this purpose, the government is developing and applying the Building Energy Management System (hereinafter, referred to as "BEMS", Smart plug, etc.) while the researches on new renewable energy development. BEMS, which is applied with focus on large buildings, is inducing energy management of the entire building through energy measurement and data management, but considering its economic efficiency, it's very difficult to apply BEMS to small & medium-size buildings. Hereupon, this study intends to implement the case analysis of deterioration and economic efficiency of major equipment in buildings on the basis of electricity consumption which has been measured targeting small & medium-size buildings for a certain period by taking into account that equipment deterioration is a contributor to the increase in energy consumption.

Small-size buildings are not designed by professional structural engineers in Korea. Therefore, their seismic performance can not be exactly estimated because their member sizes and reinforcement may be over- or under-designed. A prescriptive design criteria for the small-size buildings exists, but it also provides over-designed structural members since structural analysis is not incorporated, so it is necessary to revise the prescriptive criteria. The goal of this study was to provide an information for the revision, which is seismic performance and capability of small-size reinforced concrete moment frame buildings. For the study, the state of existing small-size reinforce-concrete buildings such as member size and reinforcement was identified by investigating their structural drawings. Then, over-strength, ductility and response modification factor of the small-size reinforced concrete moment frame buildings were estimated by analytical approach along with seismic performance check. The result showed that they possess moderate over-strength and ductility, and may use slightly increased response modification factor.

Since the execution of structural design by professional structural engineers is not mandatory for small-size buildings in Korea, structural design is conducted by architects or contractors resulting in concern about the seismic safety of the buildings. Therefore, the Korean Structural Engineers Association proposed dedicated structural design criteria in 2012. The criteria were developed based on a deterministic approach in which the structural members are designed only with information of story and span length of the buildings and without structural analyses. However, due to the short time devoted to their development, these criteria miss satisfactory basis and do not deal with structural walls popularly used in Korea. Accordingly, the Ministry of Land, Infrastructure and Transport launched a research on the 'development of structural performance enhancement technologies for small-size buildings against earthquakes and climate changes'.. As part of this research, this paper intends to establish direction for the preparation of deterministic structural design guidelines for seismic safety of domestic small-size reinforced concrete buildings. To that goal, a typical plan of these buildings is selected considering frames only and frames plus walls, and then design is conducted by changing the number of stories and span length. Next, the seismic performance is analyzed by nonlinear static pushover analysis. The results show that the structural design guidelines should be developed by classifying frames only and frames plus walls. The size and reinforcement of structural elements should be provided in the middle level of the current Korean Building Code and criteria for small buildings by considering story and span length for buildings with frames only, and determined by considering the shape and location of walls and the story and span length as well for buildings with frames plus walls. It is recommended that the design of walls should be conducted by reducing the amount of walls along with symmetrically located walls.

The purpose of this study is to find out the characteristics of area and spatial elements according to the building size and provide the guidelines for space planning of the child care center. This study used the content analysis method and analysis was made on the floor plans for 51 cases and the floor plans were converted to Autocad drawings to analyze the area. The results of this study were as follows; 1) Child care centers over 70% were single-attached building types which made it possible for creating outdoor environments for children. However, most small-size centers which had under 50 children did not have the facilities for outdoor activities. 2) In terms of spatial elements, the basic spaces of the small-size center were the classroom, bathroom, kitchen, office and reference room. The medium or large size centers had extra rooms for special activities and service spaces in addition to the basic spaces. 3) Classroom area per child was 2.65 m2 on average. Space composition ratio on average for care, staff, and service was programmed by 57%, 9%, 34% respectively. Small-size center had relatively more care space when compared to the others. In the case of large-size centers, there was a tendency that service space was increased, but care space was decreased.
