Along with the rapid supply of apartments, bathtubs are becoming a must-have item for our lives, but research is very insufficient. This study is an empirical case study for formalization of taciturn as a long-time worker in the bathtub field. Bathtubs are developing different types of materials due to various factors, and we would like to draw characteristics based on their contents. The bathtub is characterized by its materials according to its manufacturing, housing structure and distribution process. First, it is a locally produced product because import and export is difficult. The second depends on the building soccer team, such as wet and dry. Third, it is different in relation to industries such as manufacturing and distribution. I would like to suggest the differences between the fourth countries. We hope this research will serve as a cornerstone for the study of bathtubs, and we hope it will be useful for those involved.

The purpose of this study is focused to the historic changes of Yungnam-Ru(嶺南樓), which are based on the site layout, and architectural forms in architectural building history and historic periods analyzed with the historic reference, paintings, and photos. This study is to search the alteration of the types of axis and the formation of spaces in Yungnam-Ru which is the Ru-Gak(樓閣) The conclusion of the architectural changes from the historic period and architectural form which is the belows. The first Yungnam-Ru by name had been used to be called, before it was re-called Yungnam-Ru by Kim Ju in 1365. Therefore, the hypothesis in naming Yungnam-Ru form assumption that the building under the name of Yungnam-Ru was re-named by Kim Ju from the Old Budist Temple called Yungnam-Sa, should re-considered in history. The second, it is considered that Milyang-Sibyi-Kyungdo(密陽十二景圖) as the painting can only be seen the site layout in 1542. It could be compared the differences of the site layouts from in 1542 to the present time. At that time Nyungpadang(凌派堂) was connected the main buildings called Yungnam-Ru Chimrudang(沈流堂),building was seperated with the Yungnam-Ru at that period. In 1542, the main Building(Yungnam-Ru) was consist of 5 spans of columns(from the front) and 2 spans of columns(from the side). Now, the main Building(Yungnam-Ru) has the 5 spans of columns from the front, and two spans of columns short from the side, compared to the present facade. At the past, Chimrudang(building) has the two spans of columns and one span of columns short, compared to the present facade. The third, It supposed that main building, Nyungpadang and Chimrudang in the composite of facade was connected with Wolrang(月廊) and Hunrang(軒廊) after invatioin from japan in 1592. 1844, (Chosun dynasty, Hunjong 10) the Yungnam-Ru was re-builted by maintaining the same concept in site layout of the past, and finally the three buildings was put together with Wolrang and Hunrang. As a result, the plan of the Yungnam-Ru was expanded with many aspects. From 1542 to 1844, the present site-layout gradually completed with three buildings which was spatially connected. The forth, in the middle age of Chosun dynasty, after added Gaeksa(客舍), the building is for the government officer staying temporally from outside province) in the site, the site layout was greatly changed with volume of building. In 1844, the Yungnam-Ru as the Nugak belongs to Miljukwan(密州館) was expanded spacially and formally. After that time, the burned buildings could not have been re-built because of aspects in government ability and economical ability.

A modular specification is a contract document that specifies the requirements of production, transformation and installation in a modular construction. A problem of the currently used specification is that it does not guarantee the level of performance required by the modular construction and fails to accommodate unique characteristics of each construction because it widely uses the standard specification as it is. This study proposes a specification that reflects the unique feature of modular construction in order to improve the quality of modular construction. Research focuses on the leakage in waterproof and mechanical equipment because it is the area with the highest rate of defects. This study suggests ways to improve the modular specification as follows: 1)Descriptive specifying (following MasterFormat) 2)Propose leakage verification method and test clause 3) Reflect characteristic of modular construction. Proposed modifications to modular specification are reviewed by experts for validation and their opinion verifies suggested improvements as a way to secure the quality of modular construction and to promise characteristics of the modular specification. This improvement will be used for reference when writing construction project specification, which can be an important contract document, so that it could lower occurrence rate of the modular defects.

Since the late 20th century, post-modern society has needed new styles in environmental design. The land art begun during that time supplied the momentum for the birth of the hybrid environmental design. The new design approach, focusing on land form and landscaping begun with land-form architecture, raised a powerful current of hybridization in the environmental design genres. The new picturesque landscape design distinguished by manipulated land forms and sublimated aesthetics appeared under the influence of land art and land-form architecture. Similarly, landscape urbanism was formed by the fusion of landscape architecture and urbanism. Therefore, the representative hybrid styles in environmental design appear as new picturesque landscape design, land-form architecture and landscape urbanism. With the new, strong interest in land and landscape, this same new interest was given to 'time' on account of the dynamics and indeterminacy of urban society. This new interest in land and time gave rise to new hybrid methodologies for environmental design such as mapping, diagramming and folding. These three tools have been applied most comprehensively in landscape urbanism. The 'fold' is the most popular design tool for most of the hybrid genres. The 'diagram' is the second-most popular design tool mostly for landscape urbanism and land-form architecture. Mapping is being actively applied to landscape urbanism and passively applied in new picturesque landscape design. In general, landscape urbanism seems to be a timely and suitable alternative for contemporary urban society. It displays very high potentials in the regeneration of the locality through the comprehensive hybrid methodology. It is necessary to actively engage in and develop landscape urbanism fit the local needs.

A new hybrid oedometer cell is designed and manufactured to investigate a behavior of soft soils by using elastic and electromagnetic waves during consolidation test. Bender elements, which generate and detect shear waves, are placed in the top cap and the bottom plate and mounted on the oedometer wall. Double wedge type electrical resistance probe, which measures local void ratio change, is positioned onto the top cap of the oedometer cell. The bender elements and the electrical resistance probe are anchored into a nylon set screw with epoxy resin. The nylon set screw with epoxy resin minimizes directly transmited elastic waves through the oedometer cell due to impedence mismatch and allows for easy replacement of defected bender elements and electrical resistance probe. Primary consolidation time can be estimated from the slope of electrical resistance versus log time curve and the evolution of shear wave velocity. The shear wave velocity can be used to assess inherent anisotropy when disturbance effects are minimized because particle alignment affects the shear wave velocity. The void ratios evaluated by the electrical resistance probe are similar to those by the settlement during consolidation. This study suggests that the shear wave velocity and the electrical resistance can provide complementary imformations to understand consolidation characteristics such as primary consolidation, anisotropy, and void ratio.

The disturbance zone and measured values are affected by the size of the penetrometer. The local value may be measured by the smaller penetrometer. An ultra small Micro-Cone penetrometer (5mm in outer diameter) is designed and manufactured to characterize soil properties with minimum disturbance during penetration tests. The tip resistance is measured by using stain gauges attached near the Micro-Cone. In addition, the friction sleeve is adopted to effectively remove the skin friction from the tip resistance. Design concern includes the installation of stain gauges, circuits, penetration systems, penetration rate, sampling rate, operating temperature, and calibration. Application tests show that the clay interface, and the soil layers consisting of clay and sand are clearly detected by the Micro-Cone. Furthermore, the cone tip resistances measured by the Micro-Cone and the miniature cone (16mm in outer diameter) are similar. Note the resolution is much higher in the Micro-Cone. This study shows that the Micro-Cone may effectively detect the soil interface with high resolution, and with minimum disturbance.

The purpose of this study was to search the architectural forms including the residence plan and wooden structure and the measuring unit in building sites named Bang in Gyeong_Ju, the capiatal of Silla dynasty. It includes the following three historic sites: JaMaeJung-ji, the east district of HwangLyong-sa (S1E1) and InWang-dong historic site. Especially, the data from excavating and studying the east district of HwangLyong-sa were very precious and meaningful. The results were as follows: 1) There are individual characteristics at the sites of JaMaeJung-ji, the east district of HwangLyong-sa and InWang-dong. 2) It is assumed that the builldings of the east district of HwangLyong-sa had most various types of plan and various types of wooden structures. 3) There were various types of wooden structures like as symmetrical or asymmetrical style, regular columnar or irregular columnar style and a third purlin location or a forth purlin location. 4) This study also showed there's a high probability that buildings at Bang sites had been built by the Tang dynaty scale. In Silla dynasty, there was similar tendency to BackJe Dynasty in the way that measuring unit changed according to the times.

Eco-village is emerging as one of housing styles in the modern age. The common space in Eco-village uses environment-friendly materials while residents appear to aspire to a community. The common space in Eco-village offers a place of interchange and interaction for both visitors and residents as a transit area connecting dwelling units. It also forms the sense of community and serves as a space that builds friendly relations among residents. However, there seems to be a lack of research compare to its various roles and importance for this common space, which is an significant factor in establishing Eco-village plans. The purpose of this study is to provide research data by creating a layout drawing of Eco-village and reveal the characteristics of space boundary and practical use of common space through case studies on villages. This will serve as actual data in designing common space which would correspond to the purpose of Eco-village planning.

The current construction industry mainly uses paper-based construction documents which are produced during the whole life cycle. The paper-based information hinders to reuse the construction information, due to the inefficiency to exchange and share the construction information between designers and constructors. To overcome these problems, construction CALS/EC (Continuous Acquisition and Life Cycle Support/Electronic Commerce) has been proposed by the government. It supports efficient reusing, sharing and exchanging the construction information using digitalized drawings and documentations. This study intends to show the future applying methodologies of using the standardized key technologies in the construction CALS/EC based on the case study of Korea and several countries.

건축물의 다양한 설비는 내부 거주자의 안전, 쾌적, 위생 등 환경적 요구를 충족시켜주는 기능을 수행한다. 소방용 설비의 경우 화재발생시 인명과 재산피해를 최소화하기 위한 중요한 기능을 담당하며 평상시 자주 사용되지는 않지만 화재와 같은 사고 발생시엔 확실한 작동이 요구된다. 소방용 설비는 경년변화로 인한 기기의 성능저하 및 고장발생의 우려가 큼에도 그 특성으로 인해 고장 및 기기의 결함을 조기 발견하는 것이 어렵다. 이에 국내에서는 소방설비에 대한 점검 기준을 마련하여 이를 소방용 설비의 유지보수를 수행하고 있으나 형식적인 점검방법으로 인해 다음 점검주기까지의 성능보장이 불가능하다는 한계점을 가진다. 이러한 문제점을 개선하기 위해서는 공학적 근거에 의한 소방설비의 내구연한을 제시될 필요가 있어 국내에서도 현재까지 소방설비에 내구연한 산정에 관한 논의가 활발히 진행 중에 있으나 내구연한 산정방법과 기준에 대한 연구는 미비한 실정이다. 본 연구에서는 일본 공업회의 자주적인 대처로 산정된 소방용설비용 내구연한 사례를 분석 고찰하여 국내 소방설비 기기의 내구연한 및 교체시기 산정에 대한 기초연구를 진행하였다.
