Contrary to urban development, urban regeneration is a process of land development through conservation, restoration, and management. In particular, ecologically based urban regeneration is an attempt to improve the quality of life in an area, establish a stable settlement space, and revitalize the local economy by considering the ecological environment. In this regard, the objectives of this study were to establish theoretical concepts and analyze the successful foreign cases of ecologically based urban regeneration, and propose a direction of socio-economic regeneration along with the physical-environmental regeneration of urban areas in Korea. The study results suggest the following. First, strategies must be developed to coordinate public transportation, such as buses and subways, by considering the importance of bicycle riders, along with the sustainable-commuting system. Second, both the importance of planning parks and trails around water systems in various scales while maintaining the existing natural environment as well as using natural elements, such as electric vehicles and wind-power generation systems, were emphasized. Third, urban regeneration for increased energy efficiency requires specific architectural planning and facilities. Fourth, education and research for easy access by the public, as well as public-private partnership, will be needed in the regeneration process.

이 연구는 우리나라에 있어서의 도시로의 인구이동과 도시매력도와의 관계를 <인지-행태>론적인 관점에서 설명하려데 그 목적이 있다. Julian Wolpert (1965)의 "장소효용접근방법"으로 체계화된 이 이론의 요지는 사람들이 이주대상지를 결정함에 있어서 그 대상지의 객과적인 매력도 보다는 자신들이 갖고 있는 정보를 토대로 주관적으로 판단한 이른바 "인지된 매력도"에 좌우된다는 점이다. 이 연구에서는 우리나라의 자료를 토대로 Wolpert의 가설을 검증하여 보았다. 인구이동의 관점에서 본 도시매력도의 구성요소를 (1) 소득수준, (2) 취업기회, (3) 교육기회, (4) 주거사정, (5) 도시시설의 질, (6) 이주시 도움을 받을 수 있는 친지의 유무, (7) 사회적 성장기회 등 7개 항목으로 분류하여 우리나라의 도시들을 객관적인 매력도와 주관적인 매력도로 계량화하였다. 객관적인 매력도는 기존의 통계자료를 지표화하여 측정하였고, 주관적인 매력도는 충청북도 주민들을 대상으로 1983년 현재 인구 10만 이상의 36개 도시에 대한 매력도 순위 설문조사를 통해 계량화하였다. 이들 매력도를 독립변수로 하고 충북으로부터 각 도시로 전출된 인구를 종속변수로 하여 통계적 분석을 한 결과 객관적인 매력도는 인구이동 현상을 55-58% 설명하였으나, 주관적인 매력도는 약 95%정도 설명하는 것으로 나타나 인구이동 의사결정이 주민들에게 인지된 주관적 매력도에 크게 의존하고 있음이 판명되었다. 따라서 학교교육이나 대중매체를 이용한 장기적인 <인포메이션 프로그램>을 개발하여 농촌생활이나 중소도시에서의 생활의 장점을 널리 계몽하여 도시의 주관적 매력도와 객관적 매력도간의 간격을 좁혀주는 정책도 매우 유용한 대도시 인구분석정책대안의 하나가 될수 있을 것이다.정책대안의 하나가 될수 있을 것이다.다. 고로 본고에서는 주사제의 처방설계및 제조(방법, 공정)에 관하여 개괄적으로 논하고자 한다.약화되어 저적면적빈도분포가 정상분포 단계에 도달되기 전에 바로 platykurtic분포로 되는 것이 아니고 leptokurtic 분포적 단계를 거친다고 본다때 시간의 경과를 따라 생성되어지는 Cyclodextrin의 함량의 변화를 추적하여 4시간전후에서 최고량이 되는 것을 볼 수 있으며 동시에 포위화합물을 형성시킬수 있을때는 그 생성률이 큰 영향을 이르킬수 있는 것을 지적할 수 있다.한 특성을 보여 식품제조, 식육연화 등 식품산업 분야에서의 활용가능성이 높을 것으로 보이며, 나아가 단백질이 갖는 식품학적 기능성을 높이는 데에도 사용할 수 있을 것으로 판단된다.를 한 후 저온 냉장차를 이용하여 유통한다면 관행 유통 구조보다 고품질의 포도를 유통시킬 수 있는 것으로 사료되며 앞으로는 완숙된 고 당도(12.0~15.0Bx)$^{\circ}$ 포도를 수확 한 즉시 예냉 처리하고 저온 유통한다면 보다 신선한 과일을 소비자에게 전달 할 수 있을 것이다.갈변물질이 생성되었다. 이와 같은 결과로 볼 때, BAAG의 처리는 BAAC의 경우보다 가격은 저렴하면서도 항균력은 우수한 천연 항균복합제재로써 농산물 식품원료에 적용하여 선도유지 기간을 연장할 수 있는 효과를 기대할 수 있었다. 과일 등의 포장제로서 이용할 가능성을 확인하였다.로 [-wh] 겹의문사는 복수 의미를 지닐 수 없 다. 그러면 단수 의미는 어떻게 생성되는가\ulcorner 본 논문에서는 표면적 형태에도 불구하고 [-wh]의미의 겹의문사는 병렬적 관계의 합성어가 아니라 내부구조를 지니지 않은 단순한 단어(minimal $X^{0}$ elements)로 가정한다. 즉, [+wh] 의미의 겹의문사는

The diversity of urban landscapes is established by dynamic characteristics such as language, color, and their movement, which are the building environment, street patterns, and people. With the increase of foreign migrants in Korea, new guidelines are needed in terms of local community administration and land policy. Administrative, sociological, and geographical studies have been conducted on the steadily increasing number of foreign migrants since the 2000s, but it is difficult to establish for making safe and healthy communities through which different cultures and lifestyles of each country and ethnic group undergo some integration with the existing host society. There are limitations in identifying the lack of statistical data and the representation of a minority proportion of foreign residents. In order to analyze the core elements of the integrated strategy of the local community, the residential behavior and spatial characteristics of foreign migrants must first be identified.

Gravity model has had the major problem that the model explains the characteristics of travel behavior with only deterrence factors such as travel time or cost. In modern society, travel behavior can be affected not only deterrence factors but also zonal characteristics or transportation service. Therefore, those features have to be considered to estimate the future travel demand accurately. In this regard, there are two primary aims of this study: 1. to identify the characteristics of inter-zonal travel, 2. to develop the new type of calibration method. By employing accessibility variable which can explain the manifold pattern of trip, we define the zonal travel behavior newly. Furthermore, we suggest 2-phase calibration method, since existing calibration method cannot find the optimum solution when organizing the deterrence function with the new variables. The new method proceeds with 2 steps; step 1.estimating deterrence parameter, step 2. finding balancing factors. The validation results with RMSE, E-norm, C.R show that this study model explains the inter-zonal travel pattern adequately and estimate the O/D pairs precisely than existing gravity model. Especially, the problem with estimation of short distance trip is overcomed. In conclusion, it is possible to draw the conclusion that this study suggests the possibility of improvement for trip distribution model.

In this study, Entropy method and PROMETHEE(Preference Ranking organization METHod for Enrichment Evaluations) which is one of the multi criteria decision making methods are applied to estimate the relative inundation risk ranking of the urban sewer systems. Then, the evaluation factors were selected considering two main items to estimate the inundation risk using Entropy and PROMETHEE. In the first item considering topographical and environmental factor, average elevation, average slope, width of area, population, density of conduit were selected as the detailed factors of first item which have influence of the overflow occurrence and damage scale in urban sewer system. And, the relative reliability of sewer network was considered as the second item which can quantify the inundation appearance. Then, the reliability is estimated considering the number of overflow nodes and overflow volume simultaneously. Therefore, the suggested inundation risk evaluation method can be used as the evaluation index for sewer networks and contribute to decision making for the sewer rehabilitation policy.

In order to improve continuous success and stabilization of high-speed rail in the future, Using Frequency of high-speed rail should be enhanced by improving satisfaction of high-speed rail passenger. High-speed rail is needed to hold the priority in competition means by comparing the traits of service of domestic air lines. This study utilizes structural equation modeling to develop model for estimating factors influencing to service through conducting survey questionnaire. It also uses reliability analysis, correlation analysis, factor analysis to examine the rationalization of items and to establish hypothesis of this research. The results show that KTX contains 'inner service' item that is considered to be ameliorated and that domestic airline present low performance of 'outer service' item. In other words, moving section which partly is under a limited condition is needed to be improved. In addition, access to airport and transfer to other transportations have to be improved as they show the lowest satisfaction.

The guarantee of transportation for elderly and handicapped people is increasingly necessary owing to their growing social and economic activity. In March of 2013, a partial amendment to the law for transportation of the vulnerable was made by the government, to make more convenient transport a legal requirement. The amendment describes standards for the installation of transport facilities, and its support available. However, the adjustment of low-floor bus routes is not included. Therefore, low-floor buses are operating without consideration for the handicapped. This study evaluates the current low-floor bus system user experience by considering the residential distribution of vulnerable customers and analyzing their reasons for using public transport. As a result of this work, adjustments to current bus routes are proposed. The residential distribution of vulnerable people has been assessed using the supporting materials of the urban renewal project in Busan City, and their reasons for using public transport have been collected by a survey of the target user groups. The results show that group A, which has good accessibility, was in high demand, but provided the most limited service. Whereas group C, which also has good accessibility but was in low demand, provided its service most frequently. The data show the supply and demand inconsistencies of low-floor buses, and the inefficiency of bus route allocation. Therefore, this study proposes improvements to current methods for the effective operation of low-floor buses.

The assessment (or the evaluation) of spatial disparity is the main concern for the study of spatial disparities or spatial inequalities. In order to evaluate the spatial disparity, the regional differences have to be counted quantitatively. Several measurements have been introduced for evaluating the development potentials of each region. Most of them are the composite indices of the socio-economic variables rather than the real potentials of the region. This study attempts to investigate the spatial disparity in Korea. For the purpose, the levels of opportunity potentials of the cities have been calculated by the Potential Model redefined by Lee(1995). The opportunity potentials have been calculated for the educational, cultural, medical service, environmental sectors, income, and consumption sectors, and the spatial patterns of various opportunity potentials have been analyzed. The spatial patterns of opportunity potentials show the severe concentration on the Metropolitan Seoul area through all sectors. The next level concentration appears at the other end of the Keuyng-Bu axis. And the cities relatively high opportunity potential values are distributed along the Keuyng-Bu axis. Remain parts of the country show quietly low opportunity potential values. In particular, the southern-west and the northern-east parts show relatively very low values. This pattern appears for all sectors except for the opportunity potential of the environmental sector. It means that the spatial disparity in Korea have been promoted and enhanced by the national development policies concentrated the investment on the large cities along the Keuyng-Bu axis during the last 40 years.

When forecasting demand for a new road, a select link analysis is usually used to understand the OD pairs that send trips along paths that use the selected link (i.e., the new road). These OD pairs and their associated volumes are listed in a select link analysis. However, there is no research about other methods to obtain these results, so experts are almost always dependent on select link analysis results to obtain these results. The purpose of this study is to propose a model with a different approach from select link analysis to obtain the previously mentioned results. Time and spatial characteristics of networks are used in this new approach. Select link analysis results are used as a comparison index for the results by the proposed model. Also, two case studies (interzonal trips and intracity trips) are performed to validate the significance of the model. Consequently, a correlation coefficient between the results by the proposed model and the comparison index shows high significance: 0.82.
