Management innovation as a strategic alternative to create competitive advantages in the global market, is being actively progressed by conglomerates such as Samsung, LG and Toyoda as they cut a brilliant figure in the 21 century by using various innovation methods. However, the domestic railway sectors, in particular urban railway depots have neglected management innovation as they undertake Operation and Management in non-competitive settings of a corporate enterprise. This paper analyzes the critical success factors that have switched the most obsolete depots to a benchmark model for domestic railway depots based on the remodeling businesses undertaken in Gunja rolling stock maintenance office, Korea's first urban railway depot, along with 5S 6sigma program.

The purposes of this study were to reevaluate urban traditional houses and to propose direction for the conservation and utilization of urban traditional houses in a way of maintaining historical landscape rather than the value of urban traditional houses as components in expanded urban structure. For these purposes, we identified the characteristics of conservation and utilization of urban traditional houses by representative cases and analyzing them exhaustively, and suggested problems in the cinservation and utilization of traditional houses and solution for them. The current conservation system for Urban Traditional House in the Bukchon area is applied to non-residential Urban Traditional House differently according to the owner's consciousness of conservation because there is no support system for non-residential Urban Traditional House. Accordingly, there should be standardized criteria to maintain the landscape of the Bukchon area in terms of beauty formed by the elevation of Urban Traditional House and the continuity of roofs while accommodating various functions. As in total conservation or partial conservation, the interior remodeling of individual houses may be allowed but the three-dimensional external appearance composed of the outer walls, fences and roofs of Korean-style houses should be repaired and improved in a way of maintaining the image. In order to utilize Urban Traditional House in the Bukchon area, plans should be made in consideration of its location, historicity and tradition. We may expect the utilization of traditional cultural facilities and their surrounding areas as alternative cultural spaces. Such use of individual Urban Traditional House should be extended by linearly and areally and suggest the direction of conservation and utilization.

The current study proposesto examine the external appearance types of urban-style hanok in the Bukchon Hanok Preservation District according to their use. For this purpose, we conducted a field survey from the 12th of September to 10th of October 2005, which investigated the location, condition md use of urban-style hanok that were being used for non-residential purposes. The external elevation of the houses were observed and photographed. The results are as follows. First, there were 158 urban-style hanok used for non-residential purposes and200 cases of non-residential use. There were 69 cases of food and beverage spaces, 58 cases of small retail businesses, 38 cases of cultural facilities and 7 cases of convenience facilities. Second, among residential urban-style hanok used for non-residential purposes, 131 cases changed the external appearance of existing urban-style hanok and only 69 cases maintained the original appearance of urban-style hanok or renovated the appearance fittingly to non-residential use. Among the renovated cases, 59 involved the construction of a firewall and 10 cases involved remodeling in a contemporary style. Among the transformed cases, 40 cases exhibited a full opening to the roadside, n involved the change of external appearance components, 14 involved the extension of the courtyard and 12 involved overall improvements to a contemporary style. Third, in the case of cultural facilities and offices, many instances reproduced an urban-style hanok in the traditional style, but small retail shops and food/beverage spaces showed serious deformation. Particularly small retail shops opened the side to the road or extended the courtyard regardless of the location of the houses in order to increase the store space and, as a result, severely damaged the urban-style hanok. In addition, many food/beverage spaces remodeled their external components using tiles, bricks or metals, which were easy to maintain.

Aged apartments lack parking space and are suffering from severe parking difficulties due to the increase in the supply of private cars due to the economic improvement. Efficient remodeling technology is required as a way to solve the problem of a shortage of parking spaces, but there is a lack of establishing a technology for remodeling plans that can reflect the characteristics of various parks. This study was conducted to analyze the functions of the parking lot expansion technology using the technology tree and to derive the final technology through the function deployment. As a result of functional deployment of the plan to expand the parking lot, the fifth function was deployed and a total of 22 technologies were derived. Four types of technologies are categorized, four technologies for underground expansion, 12 technologies for underground and ground expansion, two technologies for ground expansion, and four technologies for ground-based expansion. As a result of the functional deployment of the main entrance plan, the fifth function was deployed and derived with 22 technologies. The total technologies were grouped into four categories, four technologies for direct underground entry, 11 technologies for indirect underground entry, three technologies for direct access to ground, and four technologies for indirect entry to ground. Through case verification, the detailed technologies applied to the semi-industrial complex of remodeling were identified and expert surveys and interviews were conducted to verify the adequacy of the technology tree.

The government announced the Housing Welfare Roadmap (November 2017), to expand the supply of public rental housing by reconstructing aged long-term public rental complexes. Also, remodeling projects for complexes with low business feasibility of reconstruction projects are recognized as an alternative to supplying public rental housing in urban area. This study analyzed influence factors by dividing them into project feasibility, architectural plan, urban & residential environment plan, and legal system groups in order to establish a plan for long-term public rental housing remodeling project. Futhermore, this work conducted the principal component analysis to get the principal component factors among the influence factors of each group, and the weight analysis to calculate weighting of them. In addition, major influence factors were derived by calculating the relative importance score (RIS) of each factor. Lastly this paper validated the major influence factors and applicability of the procedure to select 3 complexes that can be reviewed for remolding project among 33 long-term public rental housing complexes located in Seoul. The results of this study are expected to be useful when establishing a remodeling project plan for long-term public rental housing.

The rebuilt and redevelopment projects conducted these days surely have invited overpopulation. Its one of the culprits is the municipal ordinances which allow the floor to site area ratio to increase from 200% to 400% in a decade and the adjacent distance ratio from 1.25 to 0.8 times of height of building. Possible solutions for the overpopulation problem are as below. - The floor to site area ratio should be regulated adaptively according to various regional localities. - Draw back the capital gains coming from a rebuilding project For evaluation process; - Select a suitable plan from plurality of proposals - Gradually encourage projects towards remodeling system in the near future

The demand for reinforcement in accordance with remodeling, seismic retrofit, and change of use of the existing structure is increasing. Originally, shear wall new and extension method has been adopted a lot as seismic retrofit methods. Recently, dry seismic retrofit method that uses structural steel is mostly adopted in order to minimize spatiotemporal aspect and underpinning that occurs when a construct shear wall. We redesigned the form of old and new concrete joint high-shear ring anchor that was developed according to recent reinforcement method and determined construction method. Shear tests were performed on High-Shear Ring Anchor for steel-concrete connection. Comparison with 4 tests shows that the average of test-to-prediction ratios is 1.01.

This study aims to analyze the changes of adjacent residential area after the restoration of covered urban streams in seoul. The changes of adjacent residential area after restoration were analyzed by changes of land using, urban structure, individual lot of land and architecture to investigate relationship of the urban stream and residential change. The result as follows: the first one is the change of land use and urban structure in adjacent residential area. This change of infrastructure through stream restoration has transformed land use and urban structure in adjacent residential area. Secondly, there is the changes of the individual lot of land. It seemed that new development by combined lots would be concentrated in stream-side blocks. But, the changes of lots such as combining or dividing lots tend to be concentrated in stream-side, main road and main streets. In stream-side, commercial function of land use has changed to residential one which has restored streams landscape by transformation of lots use without changes of ownership-lots. Finally, there is the change of architecture. It turned out new building in adjacent residential area is similar to general development. However, new building in streamside is related to direction of stream. In addition, remodeling and expansion tend to change in commercial buildings on stream-side bridges of corner lots intensively. As a result, it is related to expectation of architectural activation and improvement of sidewalk environment by stream restoration.

Purpose: Korean society has already entered an aged society but there aren't many evidence-based studies on the elderly-friendly design elements in the apartment environment, which is the main residential type in Korea. The main purpose of this study is to verify the necessity and expandability of the outdoor environment design in the public rental apartment complex through the evaluation of the effectiveness and satisfaction of SMG(Seoul Metropolitan Government) Cognitive Health Design Project in GR 1 apartment complex. Methods: The research subjects were GR 1-complex as experimental group and the nearby Wolgye Deer 1-complex as control group, both public rental apartment and located in Seoul. As a research method, the survey was conducted before and after the implementation of SMG project for residents of the apartment. A total of 200 preliminary surveys and 203 post surveys were conducted. Results: As a result of this study, residents' accidents related safety have decreased, and both the frequency of use and satisfaction of most facilities have increased. It is noteworthy that the increase in cognitive items in the post-survey. Also, 74.5% of the residents evaluated that the complex was better to live after the project was implement. Implications: The fact that the preliminary surveys were not conducted for the same person is considered as the limitation of the study, but it is meaningful in that it systematically assesses the effectiveness of the project on the cognitive health of the outdoor residential environment towards age-friendly city.
