In order to apply the drywall system to the interior wall of the post & beam structure, the existing detail drawings and construction specifications must be revised. LH selected drywall systems suitable for post & beam apartment housings and revised their standard detail drawings and construction specifications. This paper describes the major revision of the plasterboard partition wall in the LH construction specifications and standard detail drawings. The main policy of the revision work was to prevent defects by ensuring the construction quality and to eliminate adverse effects on the subsequent processes.

2015년 9월 새로운 교육과정에 대한 총론 및 각론이 확정 고시될 계획이며 이에 따른 교과용도서 개발이 이루어지게 된다. 교과서는 교수 학습 내용의 방향과 범위를 결정하고 통제하는 역할과 기능을 지니고 있기 때문에 학생과 교사가 만나는 수업의 장에서 교과서는 매우 중요한 역할을 한다. 따라서 교과서의 내용 구성에 따라 수업에 많은 영향을 미치게 된다. 본 연구는 교과서 내용 영역별 세부 학습내용 구성의 차이점을 정적분의 활용을 중심으로 분석하고 이를 토대로 설문을 구성하여 14개 시 도교육청 고등학교 수학교사 369명을 임의표집하여 설문조사를 실시하였다. 설문 조사 결과를 분석하여 교과서 내용 영역별 세부 학습내용 구성의 차이에 따라 발생되어질 수 있는 교사의 교수 내용 및 방법과 학생들의 수학 학습에 미치는 영향을 탐색하였다. 이를 통하여 교과서 세부 학습내용의 구성에 대한 시사점을 제공하고 교과서 편찬 체제에 대한 개선점 도출을 그 목적으로 하고 있다.

Electron microscopy and X-ray diffraction have together played a key role in our understanding of the molecular structure and mechanism of contraction of muscle. This review highlights the role of electron microscopy, from early insights into thick and thin filament structure by negative staining, to studies of single myosin molecule structure, and finally to recent high-resolution structures by cryo-electron microscopy. Muscle filaments are designed for movement. Their labile structures thus present challenges to obtaining near-atomic detail, which are also discussed.

In recent years, dramatic advances in information technology have motivated the construction industry to improve its productivity. Most construction companies are trying to utilize some new information technologies for enhancing the structure quality, shortening construction time, and reducing the construction cost. Digital Mock-Up (DMU) technology utilizes 3D CAD/CAM system that shows the shape of a structure on the computer screen. By modeling and assembling the structure in 3D dimensional environments, some errors in design can be found before or during construction. In this paper, DMU technology was applied to the detail design and construction of In-Cheon Bridge and its effectiveness was evaluated. All components of a PSC box girder segment were modeled and assembled by using of 3D CAD tools and then, some interferences between components and errors were found and revised appropriately before construction. Consequently, DMU technology would improve the quality of the structure and reduce time and cost for construction.

This study aims at providing comprehensive data which would be helpful to establish a web shopping mall by analyzing the structure of web fashion star shops which have recently emerged as a result of advances in digital technology and communication. For the purpose of analyzing VMD strategy used in web fashion star shop, we adopt both of the documental and empirical research methods, based on which we examine the concept of E-commerce and current business situation of web fashion star shop industry, and then analyze the main page, product category page and product detail page in a star shop featured by a male pop star within a web shopping mall. According to our analysis of the structure of web fashion star shop, in case of open market, a banner with star's image on it leads to star shop when people click on the link of the banner, and in case of independent mall, they show each star's unique style in the main page. Product category page is linked to each product detail page which presents items of various fashion coordinates, satisfying needs of consumers to follow star's trendy fashion sense.

The purpose of current study is about how to construct wall-type APT in slip form and Deck plate applied different connection of materials that wall and slab. A proposal construct's solution is using the continuous a binding string that the main of contents are slab or stairs which horizon structure part construction is joined the vertical structure part, new we Proposed of 2 solution that new technology development. We'll suggest that the development is in the construct of higher stories APT more better other construction method. We expect that the new method is good but we have many things to solute themes. Thus, we decided that this development contents are needed that correct structural investigation and constructor's security of speciality and through a fact construct, correct verification.

Wind pressure characteristics on a double tower high-rise structure, which is disturbed by surrounding buildings, were investigated using large eddy simulation (LES) and 1:300 scale wind tunnel experiments. The computational simulation technique and wind tunnel experimental technique were described in detail initially. Comparisons of computational results with the experimental data have subsequently been carried out to validate the reliability of LES. Comparisons have been performed in detail for the mean and fluctuating pressure coefficients. Detailed explanations of each comparison were given in the paper. To study further on the pressure coefficients on the building surfaces, parametric studies on shape coefficient and spatial correlation were performed and investigated. The numerical and experimental results presented in this paper advance understanding on wind field around buildings and the application of LES and wind tunnel tests.

2거더 플레이트교는 주부재인 바닥판과 거더, 2차부재인 가로보, 수직보강재 및 수평보강재 등으로 구성되어 있다. 2거더교는 AASHTO와 국내의 도로교설계기준에는 하나의 거더가 손상되면 그 교량의 기능과 안전성에 문제가 야기되는 단재하 경로 구조로 규정되어 있다. 이러한 이유 때문에 2거더교의 피로균열은 교량의 안전성에 심각한 영향을 줄 수 있다. 따라서 본 논문에서는 2거더교에서 피로균열 발생 가능성이 높은 수직보강재와 거더 복부의 연결부를 대상으로 수직보강재 스캘럽 곡률반경 및 복부두께를 변화시키면서 피로 평가를 수행하였다. 이 결과에 기초하여 피로에 유리한 구조상세 및 간이 평가식을 제안하였다.

An automation of standardized rebar shop drawing is necessary for easy application by improving workability, prompt preparation to field change request and easy revisions of shop drawing. Through investigating problem of current rebar shop drawing, we found that standardization of reinforcing detail, standardization of rebar expression and automation of rebar shop drawing program for the sake of designer is needed. We will investigate disagreement of reinforcing detail between building code and how worker build structure for standardization of reinforcing detail, demands of companies participated in rebar process for standardization of rebar expression and proper algorithm with selectable level of inputting data for automation of rebar shop drawing program for the sake of designer.

This study aims to make detail examination of smallholder dairy farming systems in the Nongpho Dairy Cooperative. Forty-three dairy farms were selected from three geographical areas i.e. irrigated area, municipality area, and factory area. Within each area some number of sample farms were selected from each of the three levels of farm and animal crowdedness (very crowded, crowded, and not crowded farms). Detail data were collected during 1996 to 1997, they were socio-economic conditions of the sample farms and farmers, dairy production systems and management of resources (animals, bam, feeds, stocking rates, herd structure, animal body conditions, milk yield and milk quality, manure and farm wastes management, and other related items). Detail information useful for the improvement of farm production efficiency were discussed. It was very clear that much improvement of smallholder dairy production can be achieved if the recommendations given by this study were implemented.
