In recent years, the architectural interest in the apartment design has been getting focused on qualitative improvement and design differentiation. Especially the facade design differentiation is one of the most important elements in this matter. The purpose of this study is to provide the basic informations that can be referenced when architects are dealing with exterior design by analyzed design types and characteristics of apartment entrances. Target apartment of this study was whasung dongtan the 2nd phase new city districts which was planned to solve a housing shortage in the capital region. Having examined eleven pilot districts, four 1st construction areas, and eight 2nd construction areas, - total 23 complexes - 282 apartment entrances in 212 apartment buildings were carefully researched. Apartment entrance design can be divided into 15 different design elements: design types and combination types, direction, shape, height, approach types, exterior wall finishes of entrance, exterior wall finishes of lower parts of apartment, handrail types of slope, floor finishes of slope, distribution ratio of piloti, ceiling height of piloti, floor finishes of piloti, space use of piloti, window establishment between piloti and elevator hall, landscape elements of piloti. Design characteristics of building entrances were also analyzed in 4 groups (I, II, III, IV) divided by construction contractors ranking. In conclusion, first, design types and combination types can be classified into 15 different kinds, and the group I and II tend to show wider variety of entrance combinations. Secondly, the height and volume of extrude entrance type tend to increase in the group I and II. Third, the spatial configuration of pilotis appears to show more of 'pass + store + break' rather than 'access', as we get closer to the group I.

In General, post-installed dowel bars are used as a shear connector to ensure the composite actions between new slabs and existing slabs in an apartment remodelling constructions expecially for enlarging the interior space outward the existing buildings. But, it has not been checked that the connection performance between existing and new slab is satisfactory not only for the structural safety condition but also the for serviceability and dwelling requirements. In this research, an experimental works were presented to evaluate the load transfer capacity for the planar joints between existing and new slab. The existing slabs were obtained from the existing apartment housing which will be demolished. Test results showed that the planar joints with post-installed dowel bars behaved in full composite modes until ultimate capacity of test specimens, so sufficient ultimate and serviceability performance are confirmed.

Recent rise in the supply rate of new public apartment houses leads to an increasement in disputes regarding the construction quality of the apartments between the residents and the construction companies. According to the dispute cases filed for claiming the collective defect repair fees, inter-layer concrete joints turned out to be the most frequently disputed item. For this reason, this study selects the inter-layer concrete joints to further analyze the primary causes and details of each dispute case. From the results of this study, three primary causes of the disputes are found, which are 1) the absence of standard specifications for construction quality control and management after construction; 2) the absence of established standards for repair when construction defects are found; and 3) the fact that the court grants generous compensation for disputes concerning the apartment houses. In order to prevent construction defects in inter-layer concrete joints, this study provides three suggestions including 1) the current standard specifications for inter-layer concrete joints should be further specified by the Ministry of Land, Infrastructure and Transport; 2) a construction defect should be judged according to the compliance to the standard specifications; and 3) a clear and institutional protocol needs to be established for defect repair in cases that new public apartment houses have been judged to have defects.

The corrosion failure analysis for the heating pipeline of apartment was performed. Usually, the heating pipe was layed in the concrete. However, it was known that the corrosion problems could be induced by admixture containing chlorine such as set accelerant. antifreezer and so on. Therefore the new construction method using stone ash instead of concrete was attempt to solve these problems. However water leaking accidents by corrosion occurred after 1 month from the completion of the apartment. In this paper, the reason of corrosion failure was investigated by the field study and laboratory analysis in many aspects.

Recently, the Busan Economy has been depressed because of the constant economic slowdown. This also causes severe damage to the construction industry. This study focuses on The Apartment Building Type-Factory Business Incubator in the university paying attention to the construction company who struggles to make a new item of business in this aggravated state of the building business. There are no universities who operate The Apartment Building Type-Factory Business Incubator until now and there are no related data or researches at all. With this in mind, this study is to perform a feasibility study on inducement of The Apartment Building Type-Factory Business Incubator in the University in Busan area. In consequence, feasibility of Policy was sufficient and this study could draw a result of stable returns. Through this business, this study expects that schools, construction companies and enterprises who want to start a business can get the synergy among each other.

The purpose of this study is to provide the systematic report and analysis about Apartment VE application in Design Phase. In this study, the method of VE application is classified into foure groups-changing materials, changing a method of construction, acceptance of new technology, and use of new device. The facts found in this study can be summarized as follows. Application rate of VE is highest in building circumference parts. The main reason would be that there are many applicable factors according to locations, types of work, etc. Parking lots also show similar results with the same reason. It means there are a lot of possibility to adapt value engineering in these steps during the work. So far application of value engineering has been so limited that just small changes of process or method have been tried. One reason is the lack of challenging and the other is some characteristics of construction work which is very difficult to fix after completion. In the future, it would be more efficient to apply new technology and new device in construction work. Though these attempts have been ignored in Korea so far, there are still lots of possibilities to be developed in value engineering.

Since the beginning of our military history, we are continuously interested in supplying apartment for military officers. So we possessed 72,361 households and used in 2002 however, $18\%$ of those are over 20years and need to be remodeled Department of Military has taken this fact seriously To solve the problems, they built more new buildings, rent public buildings and remodeled the old one But, The procedure of present military apartment remodeling has many problems at the stage of evaluating the priorities in various remodeling projects which have been caused from lots of corps. I've reviewed the study of military apartment business and applied the AHP(Analytic Hierarchy Process) method which is effective to evaluate the priority in various groups' decision.

In the construction industry, off-site construction (OSC) is drawing attention as a production method due to changes in working hours and the supply and demand of manpower. In 1991, there was a policy of spreading and expanding the use of precast concrete (PC) apartment homes, but they have not been actively used so far since they were discontinued due to quality problems. In this study, policy tasks were analyzed to motivate the application of OSC-based PCs in the apartment housing sector, and policy directions were derived by conducting focus group interviews (FGI). Nine policies are suggested regarding the following topics: PC apartment supply quantity provision, priority application of public housing, priority supply of public housing, preferential floor area ratio, funding, tax support, improvement of business area structure, improvement of delivery method, factory certification system, and training of experts. The results of the FGIs are as follows. First, in order to revitalize PC apartment homes, leading efforts from the public sector are required. Second, rather than reorganizing the business sector or introducing a new delivery method, a policy direction that induces the strengthening of cooperation is desirable. Third, PC activation should be promoted on an institutional basis for securing appropriate construction costs and quality.
