저영향개발(Low Impact Development, LID) 시설들은 미국 일본 등 선진국을 중심으로 관련법에 따라 개발 및 적용 되어왔으나 국내에서는 최근에서야 LID 시설을 적용할 수 있는 제도적인 틀을 구축하고 있는 실정이며, 국내 여건에 맞는 LID 시설을 개발하여 그 효용성을 검증하기 까지는 상당한 시간이 소요될 것으로 판단된다. 서울시는 2014년 '서울특별시 빗물관리에 관한 조례 전부개정조례'를 발표함으로써 한국형 LID 시설을 대단위로 적용 하고 검증 할 수 있는 발판을 마련하였다. 서울시의 2014년 전부개정조례에 따르면 시장 및 구청장은 저영향개발 계획 수립의 실효성 확보를 위하여 저영항개발 사전협의 제도를 마련하여 시행하여야 하며, 시장은 저영향개발 지구단위계획을 수립하여야 한다. 이에 따라, 본 연구에서는 실제로 적용 가능한 투수포장 주차장을 설계 할 수 있도록 투수 주차장형 LID 시설을 검증할 수 있는 투수효율성 검증실험단지를 설계 및 구축 하였다. 과거 도심의 우수배제는 중앙 집중형 시스템으로 단기간에 우수를 차집하여 배제하는 방식이었으나, 근래에는 집중형 우수배제 시스템의 위험성, 경제성 그리고 용량한계 등 여러 가지 문제점이 부각되면서 분산형 시스템으로의 전환이 이루어지고 있다. 물순환도시 및 지속가능한 도시 등이 분산형 우수배제 시스템의 예이며, 주차장, 도로, 건물 등 불투수 표면으로부터의 우수를 지면으로 침투 및 침루시키는 방법 등을 활용하여 건전한 물순환을 꾀하고 있다. 침투 및 침루 능력은 각각 포장체 및 포장면 하부구조의 재료와 밀접한 관련이 있으며 재료의 선정은 하부구조의 안정성 확보를 고려하여 선택되어야 한다. 또한 우수 배제를 위한 유공관은 접합점에서 강도를 유지하면서 효율적으로 유수를 배제할 수 있어야 하며, 저류조 설치는 강수의 활용목적에 맞게 선정되어야 한다. 이러한 투수 주차장형 LID 시설은 하나의 시스템으로서 포장체의 재료에 따른 공학적 성질, 하부구조 구축방법 및 재료 선정 그리고 유공관 배열 등에 따라 그 시스템의 거동이 변화하므로 기존에 행해왔던 단순 재료실험으로는 투수성 주차장의 우수배제 시스템을 평가할 수 없다. 따라서 본 연구에서는 이를 검증할 수 있는 투수효율성 검증실험단지 설계 및 구축하였다.

This study analyzed the housing market before and after the New Stay movement which was introduced in 2015. In this study, the territories having a New Stay Project and non-involved territories were analyzed based on the apartment price changes according to supply for 12 months before and after the movement date. This study used the difference-in-differences statistical technique. A comparison was carried out in Michuhol-gu, Incheon between Dowha-dong where a New Stay Project was executed, and Sungeui-dong where no project was executed, based on the movement date. It was seen that the price level in the former territory was higher than the latter demonstrating that the introduction of the New Stay Project in Dowha-dong lowered the apartment prices nearby (Sungeui-dong). A comparison in Gwonseon-gu, Suwon between Omogcheon-dong where a New Stay Project was executed and Gosaek-dong where there was no such project, based on the movement date showed that the introduction of the New Stay Project in Omogcheon-dong seemed to lower or stabilize the apartment prices nearby (Gosaek-dong). These results imply that the apartment prices in nearby areas can be stabilized if the supply volume of company-type rental houses is increased.

The supply of housing can be understood through a close relationship with the urbanization phenomenon. Through industrialization and urbanization, many cities have implemented systems and policies for housing supply due to population concentration in cities, poor housing quality, and lack of housing. In the case of the Netherlands, the Housing Act was enacted in 1901 to improve the residential environment during the period when the population was concentrated in the city, and various efforts were made to expand the housing supply. Through this process, we understand the background of collective housing types in the Netherlands and analyze the application stages of contemporary residential housing planning in Rotterdam and Amsterdam. On the other hand, through the experience of Western society, we examine how to view the problem of multi-family housing types in our society, where the proportion of apartments is continuously increasing.

After announcing a special law for promotion of urban regeneration, urban regeneration project expand a scale. The urban regeneration project is purposing of increasing the public well-being and elavation quality of life citizen. But it is comprehention the making many conflict in phase of project promotion. A project is taken participation many stakeholds. So it is generated a multiplicity of conflict. It is survey placing an example of conflict to basis of paper news. So an example of conflict is studied total 44. Among of them, phase of project operation and management disposial was occupied to many ratios. The participation of the residents made only to specify the project district. What doesn't reflect the opinion of residents cause of after approved to specify It is classified those conflicts by procedure to study. It will make reduce the government role and between the residents and contractor will enable coordination comment in way to resolve conflicts between the subject's participation. That is to say, reflection the opinions of residents to actively of way is presenting variation of the process and change in the choice way of construction company.

The government has been operating residential improvement projects through the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents" as a type of a remedial measure for deteriorated residential areas. However, in recent years, the residential improvement projects have experienced difficulties due to the effects of various factors including the slowdown in economic growth. After observing the depression in a number of projects, various studies have been carried out to investigate the causality and improve the promotion of the residential improvement projects. In the trend of research, this study aims to analyze the effects of land and building characteristics on the improvement projects of Busan Metropolitan City. The dependent variables of the study represent different phases of improvement project as specified in the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents". The independent variables represent land and building characteristics which refer to the criteria used in the designation process of maintenance area according to the act. The empirical analysis uses the ordered logit model. The results from the analysis suggest that geographical condition, factors related to the number of union members, factors related to the parcel price and condition of a location have impact on the promotion of the improvement project. The results of the analysis show that majority of the factors are related to the economic feasibility of the projects. Residential improvement project is a part of urban planning projects that rehabilitates deteriorated residential environment, and it is closely associated with the quality of life of public. Accordingly, we hope that such projects are reasonable and take effective approach to those with urgent needs rather than to focus on profitability. Also, potential administrative and economical loss should be avoided by taking necessary planning measures in advance.

This study investigates business demands for firms operating in the Busan Sasang Industrial Area for the proposed knowledge-industry innovation base. Diverse improvement arrangements are proposed for revitalization of the industrial area. For these purposes, a questionnaire survey was conducted for the examination of physical conditions and enterprise demands among firms. The major findings are as follows. Firstly, judging from the examination of physical conditions, the study area has presented a lower rate of roads and smaller individual lots of land, which would contribute to a worsening business environment for small business owners. Secondly, business request for industrial-area innovation, pilot project needs, and expected impacts demonstrated higher scores. Thirdly, an absolute majority of firms strongly supported the proposed knowledge-industry innovation base and requested an R&D center as the first anchor facility. Based on these findings, guidelines are proposed for an institutional rearrangement plan. First of all, specific field surveys dealing with networking issues and industrial dominance should be immediately carried out. In addition, the proposed knowledge-industry innovation base should be equipped with significant power of influence for the adjacent industrial areas. Lastly, major stakeholders should upgrade the cooperative mechanism for innovative change in the regional industrial complex.

Recently, the public's interest in quality of life and good design has increased, and the opportunities for their participation in space planning and the design process are expanding. However, the public still lacks understanding of the role(and importance) of space and environment and is not experienced in expressing their opinion on improving the urban environment. At this point, 'Built Environment Education for Kids' will be the key to understanding space and environment as future citizens and to developing the ability of problem-solving and expressing their opinions. This study aims to change the awareness of the public as well as experts, and to make a better urban space through comparison and analysis of domestic and foreign 'Built Environment Education.' In 27 countries around the world(more than 110 institutions), 'Built Environment Education' from childhood is being implemented. Such movements aim to make people participate in the space design and decision-making process by understanding a fundamental element of the built environment and space perception. In this study, the United States, Britain, Finland, Japan and South Korea's 'Built Environment Education' are discussed Above all, the definition, range and target of 'Built Environment Education' are discussed For each case, the purpose and effect, laws and educational processes, systems and roles, and examples of programs are analyzed. Through reviewing each attribute and their implications, a conclusion is drawn on the aspects we have to consider in laying the foundation for implementing the 'Built Environment Education' in Korea, such as consideration of the locality, organizing systematic networks and composing a pool of experts, building proper institutions, and establishing the role of the government. This case study of 'Built Environment Education' can help increase the awareness of the public and build their strength in establishing a better future space. Through the analysis of the purpose, laws, systems, and contents, this case study is expected to provide and build the foundation for an educational system and develop an appropriate program that best suits our society.

In Korea, the local traffic safety master plan has been established and implemented according to the Traffic Safety Act. Each local government is required to establish a customized traffic safety policy and share roles for improvement of traffic safety and this means that local governments lead and promote effective local traffic safety policies fit for local circumstances in substance. For implementing efficient traffic safety policies, which accord with many-sided characteristics of local governments, the prediction of community-based traffic accidents, which considers local characteristics and the analysis of accident influence factors must be preceded, but there is a shortage of research on this. Most of existing studies on the community-based traffic accident prediction used social and economic variables related to accident exposure environments in countries or cities due to the limit of collected data. For this reason, there was a limit in applying the developed models to the actual reduction of traffic accidents. Thus, this study developed a local traffic accident prediction model, based on smaller regional units, administrative districts, which were not omitted in existing studies and suggested a method to reflect traffic safety facility and policy variables that traffic safety policy makers can control, in addition to social and economic variables related to accident exposure environments, in the model and apply them to the development of local traffic safety policies. The model development result showed that in terms of accident exposure environments, road extension, gross floor area of buildings, the ratio of bus lane installation and the number of crossroads and crosswalks had a positive relation with accidents and the ratio of crosswalk sign installation, the number of speed bumps and the results of clampdown by police force had a negative relation with accidents.

This study was conducted to determine fertilizer nutrient and pollutant production of Holstein dairy cattle by estimating manure characteristics. The moisture content of feces was 83.9% and 95.1% for urine. The pH of feces and urine were in the ranges of 7.0～7.4 and 7.5～7.8, respectively. The average BOD5, COD, SS, T-N, T-P concentrations of the dairy feces were 18,294, 52,765, 102,889, 2,575, and 457mg/ℓ, respectively. Dairy urine showed lower levels of BOD5(5,455mg/ℓ), COD(8,089mg/ℓ), SS(593mg/ℓ), T-N(3,401mg/l), and T-P(13mg/ℓ) than feces. The total daily produced pollutant amounts of a dairy cow were 924.1g(Milking cow), 538.8g(Dry cow), 284.4g(Heifer) of BOD5, 2,336.5g (Milking cow), 1,651.8g(Dry cow), 734.1g(Heifer) of COD and 4,210.1g(Milking cow), 2,417.1g(Dry cow), 1,629.1g(Heifer) of SS and 194.8g(Milking cow), 96.4g(Dry cow), 58.3g(Heifer) of T-N and 24.0g(Milking cow), 10.2g(Dry cow), 6.1g(Heifer) of T-P. The calculated amount of pollutants produced by a 450kg dairy cow for one year were 181.3kg of BOD5, 492.5kg of COD, 899.9kg of SS, 36.0kg of T-N and 4.1kg of T-P. The total yearly estimated pollutant production from all head(497,261) of dairy cattle in Korea is 90,149 tons of BOD5, 244,890 tons of COD, 447,491 tons of SS, 17,898 tons of T-N and 2,008 tons of T-P. The fertilizer nutrient concentrations of dairy feces was 0.26% N, 0.1% P2O5 and 0.14% K2O. Urine was found to contain 0.34% N, 0.003% of P2O5 and 0.31% K2O. The total daily fertilizer nutrients produced by dairy cattle were 197.4g (Milking cow), 97.4g(Dry cow), and 57.9g(Heifer) of Nitrogen, 54.2g(Milking cow), 22.2g(Dry cow), and 14.2g(Heifer) of P2O5 and 110.8g(Milking cow), 80.4g (Dry cow), and 39.5g(Heifer) of K2O. The total yearly estimated fertilizer nutrient produced by a 450kg dairy animal is 36.2kg of N, 8.8kg of P2O5, 24.6kg of K2O. The estimated yearly fertilizer nutrient production from all dairy cattle in Korea is 18,000 tons of N, 4,397 tons of P2O5, 12,206 tons of K2O. Dairy manure contains useful trace minerals for crops, such as CaO and MgO, which are contained in similar levels to commercial compost being sold in the domestic market. Concentrations of harmful trace minerals, such as As, Cd, Hg, Pb, Cr, Cu, Ni, Zn, met the Korea compost standard regulations, with some of these minerals being in undetected amounts.
