The block-unit housing renewal project was presented as an alternative method to overcome the side effects of large-scale renewal projects while improving poor residential conditions. However, projects implementation is prolonged and even the pace of projects, which was considered an various incentives, is being delayed for the most part. In this study, delay factors are drawn by eight; conflict among association members, contract delay of joint implementation, participation paucity of constructor, inadequate project guidelines, alteration of project plan, lack of renewal project professionals, stricter loan restriction of HUG, lack of capacity of project operator. We categorized those eight factors to three aspects such as implementation, participants and proposition and suggested improvement alternatives according to three aspects.

The Don-am district is a residential area that was supplied in 1936 as a land readjustment project(Tojiguhoekjeongri). The Don-am district was newly supplied with residential areas and urban hanoks were built in large numbers. The Don-am district was influenced by urban planning and legislation at that time. These affected in the layout and plan of urban hanok. Residential block in the Don-am district were developed sequentially from the late 1930s to the 1960s. Residential block were divided by modern construction company and sold by individual lots. The blocks supplied to the Don-am district made uniformly the corner out-off(Ga gak) for creating a vehicle-centered road. So urban hanoks located in the corner plot was transformed in response to the road. Residential blocks in Don-am district was divided into three to four rows. Therefore, alleys were created inside the block. Newly made alleys consist of a privately owned road(Sa-do), a public road(Gong-Do), and open space in the site. And the alleys were used as an entry space for sharing with neighboring. Urban hanoks of Don-am district have had changed and adapted to the formation of these alleys.

본 연구는 청주시의 1970년대에 시행된 4개의 토지구획정리사업지구를 대상으로 하며, 물리적 측면에서 가구체계의 개념을 통해 지구특성을 파악하는 것을 목적으로 한다. 연구 결과 첫째, 가구의 가로 특성을 보면, 4개 지구 동일하게 현재의 도시개발 기준 대비 간선도로망과 가구로의 진입을 위한 국지도로체계는 잘 갖춰져 있는 것으로 파악되었다. 그러나 가구내의 개별필지로의 진입로가 제대로 갖춰지지 않아 개별 필지 별 건축이 어려운 상황으로 나타났다. 둘째, 가구의 형태 특성을 보면, 세장비는 평균 1:2의 비율이며, 동서방향의 장방형 가구가 높은 빈도를 나타났다. 1지구부터 3지구까지는 가구면적이 증가하는 추세이었으나 4지구는 다시 감소하여 현대적인 가구구획의 형태로 변화하는 양상을 띠었으며, 가구면적이 클수록 접도율이 일관성 있게 낮아지는 것을 알 수 있었다. 셋째 필지배열 특성을 보면, $4{\times}4$이상의 다열구조를 갖는 가구의 빈도가 1~3지구 까지 높았으며 4지구에서는 상당히 개선된 것으로 파악되었다. 특히 정방형에 가까운 가구는 접도율이 열악한 과다열 필지구획이 되어, 주거환경을 개선하는데 어려움이 있을 것으로 판단되었다. 토지구획정리사업에 의한 택지 개발은 가구구획이 상당히 정형화되어 있고, 그러한 주택지의 면적이 상당한 만큼 이러한 특성을 고려하여 좋은 주거지를 위한 개선방법을 찾는다면, 외곽개발 등의 난개발을 제어할 수 있는 대안이 될 수 있을 것으로 판단된다.

The purpose of this study is to find out distributional principles of the shop-houses in residential district through physical composition of residential area. Through the research that are based on literature and field survey, it analysed the relation between physical composition of residential area and the shop-houses of selected four sites under similar urban condition where land readjustment project were held. The consequences of this study are summarized as follows; 1) A road that is not penetrating the inside a residential area is seemed to have low occupancy of shops comparing to other roads with similar hierarchy. And the shops functions as convenience facilities. It can be inferred from the statement above that even a road with higher hierarchy is not easy to form commercial area if without penetrating the residential area. 2) According to the size and the arranged method of Inner blocks of residential area towards major roads, distribution of shop-houses appear to be different. In other words, when shop-houses are located along the roads, the proportion of shop was higher than when located perpendicular to the roads. 3) When the number of average lots are little and the size of block is small, usually, street ratio and the number of corners gets higher, which eventually increases the number of shop-houses.

This study aims to find the conservation and regeneration plan in terms of preserving and utilizing old wooden houses, regenerating existing buildings, and developing idle land for old dwellings located outside the southern gate of Cheongju, Korea. In the preservation and utilization of old houses, three places in the block where wooden houses clustered are created as conservation houses, and are conversed as cafes, workspaces, and homestays along with the preservation of individual houses. In the regeneration of existing buildings, the street landscape was improved through extension and renovation, new construction after demolition, and exterior renovation for one or two-story buildings facing the roadside. In the development of idle land, it reflects the layout method and open yard space corresponding to the path and orientation of the old house, and the mass was varied and segmented to resolve the medium scale. Accordingly, considering the context, landscape, and environmental aspects of the historical downtown, the development of old dwellings in downtown should shift from a uniform high-rise apartment project-oriented approach to a gradual and continuous regeneration direction.

Since Paris Climate Change Conference in 2015, many policies to reduce the emission of greenhouse gas have been accelerating, which are mainly related to renewable energy resources and micro-grid. Presently, the technology development and demonstration projects are mostly focused on diversifying the power resources by adding wind turbine, photo-voltaic and battery storage system in the island-type small micro-grid. It is expected that the large-scaled micro-grid projects based on the regional district and town/complex city, e.g. the block type micro-grid project in Daegu national industrial complex will proceed in the near future. In this case, the economic cost or the carbon emission can be optimized by the efficient operation of energy mix and the appropriate construction of electric and heat supplying facilities such as cogeneration, renewable energy resources, BESS, thermal storage and the existing heat and electricity supplying networks. However, when planning a large residential town or city, the concrete plan of the energy infrastructure has not been established until the construction plan stage and provided by the individual energy suppliers of water, heat, electricity and gas. So, it is difficult to build the efficient energy portfolio considering the characteristics of town or city. This paper introduces an energy mix optimization(EMO) method to determine the optimal capacity of thermal and electric resources which can be applied in the design stage of the real large-scaled residential town or city, and examines the feasibility of the proposed method by applying the real heat and electricity demand data of large-scale residential towns with thousands of households and by comparing the result of HOMER simulation developed by National Renewable Energy Laboratory(NREL).

주택에 대한 수요가 다변화되면서 최근 한옥주택 및 한옥주거단지에 대한 사회적 관심이 증대되고 있다. 기존에 한옥이 밀집한 지역을 중심으로한 정비사업 뿐만 아니라, 대규모 택지개발지구등에서도 한옥주택과 주거단지 개발에 대한 시도가 이루어지고 있지만, 본격적인 사업화는 이루어지지 않고 있다. 본 연구는 LH가 공급하는 신도시의 단독주택용지와 특성화용지등을 대상으로 하여 한옥의 잠재적 수요계층을 바탕으로 사업모델을 도출하고 사업모델에 대한 타당성을 검증하여 향후 사업화를 위한 방향을 제안하고자 한다. 기존에 검토되었던 고급형 타운하우스 형태의 한옥주거단지는 입지선정, 수요불일치 등으로 인하여 사업성이 부족한 것으로 분석되었으며, 설문조사 결과등을 바탕으로 계획규모변경, 용도혼합, 필지세분화등의 방법을 통해 사업유형을 6가지로 설정하였다. 사업모델 중에서 가장 사업성이 높은 유형은 블록형 집합주택으로, 이는 규모의 경제법칙(Ecnomy of Scale)에 따른 건축연면적의 증가가 분양수입의 증대로 이어진 것으로 이해할 수 있다. 소규모 한옥과 근생시설이 결합한 공동주택 모델의 타당성도 높게 나타났으며, 블록형 집합주택과 같은 동일한 사업조건을 적용한다면, 한스타일 공동주택의 사업성이 높은 것으로 분석되었다. 그 밖에 블록형 단독주택지내 고급주택 모델은 민간부문이 일반적으로 추진하고 있는 대표적인 사업유형으로서, 1호당 건설비용이 9.1억원으로 가장 많은 비용이 투입되는 것으로 나타났다. 한옥주거단지 사업성 제고를 위해서는 입지선정, 수요계층의 다양화, 주택규모의 적정화, 용도혼합등을 통한 집합화가 필요할 것으로 판단된다. 또한 단독주택용지에 한옥주택을 도입하기 위해서는 기존의 필지계획의 조정과 분할이 필요하며, 한옥형 용지등의 공급을 통해 새로운 수요에 대응하는 전략도 제안될 수 있다. 또한 기존의 획일적인 택지개발방식에서 벗어나 기초인프라(간선도로 및 상하수도)외에 조성되지 않은 자연상태의 토지인 원형지(原形地) 공급을 통한 개발방식도 검토할 수 있으며, 한옥의 지붕 및 가구구조상 1~2층 이상의 건축이 불가능하므로 경사지 형태를 갖는 원형지 공급방식의 단지조성이 토지비절감, 경관효과 등을 감안할 때 적합한 모델로 제안될 수 있다.

The SeoulMerto, operating subway line No.$1{\sim}4$, was constructed in the metropolitan Seoul with the highest population. When it was built, the design was challenged to sharp curved tracks considering the protection of buildings, cultural assets, the connection to ground roads and rivers as well as to elevated railway in some parts. Lots of residential apartments and business complex have gradually increased in the area around subway stations and railway lines according to the urban development. Consequently, Requirements of better quality of life and comfortable environment caused the citizen complain for the noise. It has become one of serious social issues. In this paper, Noise level was analyzed using noise map measured in the running train of all routes. The analysis on the noise level was conducted according to railway type, track components type, seasonal type, retirement degree of the vehicle and subway station. Especially, Noise characteristics were analyzed by noise level data measured in the inside and outside of the train with geometry types of the concrete track. This study will contribute fundamental data for the "The Development of Sound-Absorbing Block on Concrete Track" promoted on The National R&D Project.

This paper deals with 111 buildings built between 1962 and 1987, from various parts of the city of Osijek, for which, through the collection of documentation, a database is created. The aim of this paper is to provide the first steps in assessing seismic risk in Osijek applying method based on vulnerability index. This index uses collected information of parameters of the building: the structural system, the construction year, plan, the height, i.e., the number of stories, the type of foundation, the structural and non-structural elements, the type and the quality of main construction material, the position in the block and built-up area. According to this method defining five damage states, the action is expressed in terms of the macroseismic intensity and the seismic quality of the buildings by means of a vulnerability index. The value of the vulnerability index can be changed depending on the structural systems, quality of construction, etc., by introducing behavior and regional modifiers based on expert judgments. Since there is no available data of damaged buildings under earthquake loading in our country, we will propose behavior modifiers based on values suggested by earlier works and on judgment based on available project documentation of the considered buildings. Depending on the proposed modifiers, the seismic vulnerability of existing buildings in the city of Osijek will be assessed. The resulting vulnerability of the considered residential buildings provides necessary insight for emergency planning and for identification of critical objects vulnerable to seismic loading.
