Rebar work takes up big proportion in a construction work. The current process of purchasing, cutting and election, and working of rebar induces a lot of loss in rebar. This study is focused on analyzing the problem and the present condition of the process from the calculating of rebar quantifies to the actual constructional stage through surveying those who have experience in the estimation department, or the construction site of a domestic construction company. Many reform measures such as diversification of standard(i.e., 8-meter)bar, calculation of rebar quantities and construction according to the rebar election drawing, expansion of accuracy in layout plan, thoroughness in examination of layout plan in advance, utilization of the worked material, systemization of rebar control(management), and a shift in attitude of the field(site) manager were proposed as the result of the survey.

The composition of water-friendly space in the port and harbour developments provides the accessibility to the sea and thus resting & recreational function of the local citizen, which should be treated importantly for the eco-friendly coastal development. However, the high demand on water-friendly space can induce another environmental problem because most port and harbour developments require marine reclamation and the water-friendly space are made up on the reclamation area. The present study analysed the problems and suggested matters to be considered in composing the water-friendly space of port and harbour developments. The study also established the management direction by site characteristics of port and harbour. In addition, we attempt to find a plan to avoid the water-friendly space composition with environmental damage and to secure the environmental and public soundness in site selection, land use and facilities plan based on case studies.

An accurate estimation of water level variation when thewaves propagate to the coastal regionis very important for the port and harbor development plan. This study describes the application of a hybrid element model to harbor oscillation problem due to the construction of shore structure and implementation of shore boundary. The site selected is Pusan Harbor area with the third development and the Artificial Island plan. The observed water level changes at the site are compared with the result of the numerical experiment. The model gives a very important prediction of water level changes for navigation and harbor design.

The purpose of this study is to clarify the actual conditions of external space of middle and high schools in Gyeongnam Area. This article discuses about the characteristics of the external space and the site plan type of 49 middle and high schools in Gyeongnam Area. The result of analysis about site plan type, composition state of external space and area ratio of its composition of each middle and high school facilities are as follows: In facilities arrangement of middle and high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Especially, for the area is small in the composition of external space, a playground is only under $50m{\times}80m$ and outdoor learning space or resting space is not secured sufficiently. Therefore, it requires an expansion of space size and facilities for the change of school life outside class.

There remain several archiectural drawings which was made in Chosun dynasty, which are quite different from current drawings. The site plan which is composed of slanted elevations doesn't exhist in Western drawing method. This elevation development method is common in Korea, China, and Japan. These three nations also have a common point which the wooden structure are popular. So elevation development method is reasonable to represent the wooden structure. Because a drawing mehod reflects cultural character and thought, it is important to read the architectural perception at that time. In this viewpoint, I studied the characters of the drawing method in Chosun dynasty according to the peoriodical articulation of century, and how the drawing method reflects the thought at that time. And I suggested a new posibility of effective and reasonable drawing method for the wooden structure.

The porvision against earthquakes and aseismic design of nuclear power plants (NPPs) in Korea are composed of four stages: site-selection, design, construction, and operation stages, Since regulatory criteria are strictly applied in each stage, the NPPs in Korea are believed to have a sufficient safety against maximum potential earthquakes. However, it has been recognized that those regulatory criteria borrowed from U.S. should be replace by Korea-specific ones by using earthquake data obtained from earthquake observation at and around NPP sites. Also, the government made a plan after the Yongwol and th Kyongju earthquakes that the regulatory body operates an independent earthquake network in order to reinforce the earthquake preparedness of NPPs. In compliance with the government's plan, this project is aiming at deployment of an earthquake motoring network composed of four seismic stations at NPP sites to record earthquake ground motions at NPP sites, to derive attenuation formulas of various ground motions and site-specific response spectra, and to develop structural intergrity assesment program.

In the domestic physical security (mechanical security) market, there is an increasing variation in the expansion of security areas due to the infrastructure of large enterprises and small and medium-sized enterprises. In other words, problems related to on-site dispatch between companies are constantly being raised due to the limitation of physical security service s to the scope of dispatch according to the dispatch time. Therefore, in this study, based on the results of the criteria for the scope of dispatch as a criterion for dispatch time through simulations related to on-site dispatch, we propose a plan to activate the physical security (mechanical security) market in the future.

The purpose of this study is to develop a model for renewing old public buildings by incorporating mobility technology into them for the convenience of citizens' transportation and the enhancement of public services, and to propose support measures to improve the direction of implementation. The main contents and results of this study are as follows. First, the renewal target site was selected based on the technical considerations and evaluation criteria required for the renewal of public buildings incorporating mobility technology, and the construction was planned by analyzing the necessary mobility technology based on the size, area, and district unit plan of the selected target site. Second, the expected cost was calculated based on the construction plan and the financial support plan necessary for reflecting mobility technology was proposed. Third, the improvement plan of the building code system required for the development of public building renewal incorporating mobility technology was proposed. This study had limitations in that it could not reflect detailed construction costs due to the lack of design standards and experience, and it was difficult to identify specific problems due to the lack of specific operation methods and implementation cases.

It is required to study systematical on the concrete quality management to extend structure life because rebuilding effect is reducing under present condition of large sized and high stories structure. Concrete, which shows its intensity by hydrating action and a big change in quality according to hot weather and temperature, produces a lot of qualify problem under hot and cold weather Because of each specification and construction plan which does not have basic standard on site, concrete's quality is irregular and makes some defect. As a result, Daegu is turned out to be the longest area after investigating application period and days focused on 8 cities weather information about relationship between hot weather circumstance and construction environment. Therefore, we first surveyed the concrete material in the region and found out the problem of quality nanagement. Then figure out the way of solution. Moreover, we integrated concrete material quality management, which is applied differently to each site, to have equal quality and to reduce defect from construction site. And then, based on various test of construction condition and analysis of quality management item, we suggest effective concrete quality management to make concrete material construction standard guide and plan under hot weather.
