The elasticity of a model is considered most important. Without showing the proper elasticity any model cannot provide useful information for decision making. This paper demonstrates a macro model which can generate dynamic transport informations every 15 minutes. Without the Wardrop principles and the monotonicity assumptions for the link travel time and link volume relationship, the basic elements of this new modeling approache are composed of link density simulation, stochastic incremental route choice, departure time choice, destination choice and mode choice. The elasticity of the proposed model is examined based on elasticity equations and simulation results. Also the transferability from a mega city like Seoul to a big city like Daejon is demonstrated for the choice model. The issues centering around the dynamic relations among density(k), speed(u), and flow rate(v) are also discussed for the modeling of highly congested situations.

도시의 미래 모습을 결정하는 도시경관계획의 단계에서 도시 이미지가 어떻게 평가되고 있는가를 분석하여 바람직한 도시 이미지 형성 방향을 설정하는 것은 매우 중요한 선행과제가 된다. 본 연구의 목적은 시민들이 주체가 되어 도시의 이미지를 어떻게 인지하고 평가하는지를 다차원척도법과 대응일치분석을 이용하여 계량적으로 연구하는데 있으며, 나아가 전문가와 관련 공무원들의 인지 경향을 파악함으로써, 도시 이미지 향상에 기여할 수 있는 정량화된 정책 방향 설정에 도움이 되고자 수행되었다. 본 연구를 통해 도출된 결과는 다음과 같다. 1. 대전시 이미지는 주로 역사성, 역동성, 규모성 등에 의해 평가되는 경향이 강하였다. 이러한 기준에 따라 대전시는 전체적으로 새롭고 변화하는 이미지가 강한 도시로 인식되었으며, 공무원들에게는 소박한 느낌의 도시, 전문가들에게는 평범한 느낌의 도시로 인식되고 있었다. 따라서 소박하고 평범한 이미지에 대응할 수 있는 대전시 정체성과 개성을 찾는데 보다 노력하여야 할 것이다. 2. 대전시의 이미지에 많은 영향을 끼치는 상징물 혹은 상징적인 공간으로는 갑천이나 둔산 신도심, 대덕연구단지 등을 들 수 있다. 이에 비하여 유성온천과 원도심, 엑스포 공원 등은 대전시와 이미지가 크게 다르게 나타나고 있었다. 이에 따라 대전시의 이미지를 희석시키는 낙후된 시설과 상징물들의 현대적 리모델링이 필요하다. 3. 도시 이미지의 선호도를 알 수 있는 ‘좋은-싫은’의 형용사 이미지의 경우, 일반인과 전문가들에게 있어서는 모두 싫어하는 경향을 나타나고 있었으나, 공무원들은 좋아하는 이미지를 지니고 있었다. 따라서, 세 집단 모두 좋아하는 둔산 신도심이나 대덕연구단지 등과 같은 현대적 첨단산업의 이미지를 투영시킬 필요가 있다. 4. 대응일치분석을 통한 이미지 분포도에서 대전시는 행정도시와 수평적 도시의 특성이 강한 도시로 분류되었다. 기존의 단순한 도시 이미지 분석 연구와는 달리 본 연구에서는 분석 내용을 토대로 비교적 명확한 진단을 통해, 도시의 미래상 및 방향 설정에 도움을 주고자 노력하였다.

The purpose of this study was to analyze the image perception of dress shirts according to perceiver's residency and shirts style, and to investigate the shirts preference according to style of dress shirts, and to find out the men's aesthetics consciousness for shirts, and to analyze between the image perception and the usage of mass-media, for developing the possibility & strategy of the dress shirts market in men's wear market for the apparel marketers and manufactures. For this study, the data obtained from 321 respondents were analyzed by descriptive statistics, Pearson's simple correlation, ANOVA. The results from the study were as follow ; The 6 stimuli for image perception rated on 5 point Likert-type scales in the 12 features were evaluated by perceivers. By the best 3 features abstracted, shirts style concepts were decided such as, Basic style by the best 3 features of the first stimulus, and Soft style by the best 3 features of the second stimulus, and Sophisticate style by the best 3 features of the third stimulus, and Modern casual style by the best 3 features of the fourth stimulus, and Modern mannish style by the best 3 features of the fifth stimulus, and Trendy style by the best 3 features of the sixth stimulus. The modern casual style was estimated highly by respondents in Daejon. The respondents in Seoul prfered the basic style to other style. There were significant differences in evaluating between preferences of shirts style and pattern. Of the 82 respondents(26.8%) with the preference of bold london stripe, the 52 respondents estimated Modern casual style in bold london stripe. The fashion consciousness of the respondents in Seoul was estimated higher than in Daejon. But, the respondents in Daejon in the consciousness for the coordination knit cardigan and V zone was estimated higher than in Seoul. Also, the 31 respondents with the preference of Sophisticate style were the highest in fashion consciousness. The respondents estimated that the first important thing in buying dress shirts is 'Design(41.4%). and next is quality(17.8%). Results revealed that Daks ranked best brand (13.7%), and Renoma ranked best two brand (6,5%). And, the 35.5% respondents estimated that the first important information which influenced on buying dress shirts was the store display, next was internet(15.9%).

Keumsan-gun is the area where there are many mobile populations as the place to be adjacent to Daejon. There is the tendency that the empty houses at Keumsan area are increasing as 1,115 houses every year as of 2001. So, this researcher examined and analyzed the actual state by grasping the present situation of empty houses centering around Keumsan-gun. And, this researcher could obtain the following conclusion as the result that this researcher progressed the study so as to present the application scheme of empty houses. As for Keumsan-gun, farming populations are more than other city and gun at Choongcheong Southern Proince Area as the area formed with mountain groups topographically. Thus, it is forecast that the appearance of empty houses will increase, as the population decrease and the residents to have migration plan will appear higher than other city and gun in the future also. Therefore, as for the superannuated empty houses that use is impossible, to service by removing will be helpful to the image uplifting of village. In addition, as for the empty houses that use is possible, the establishment of system to connect buyers by rebuilding them as garden houses and weekend houses etc. through purchase and sale and long-term lease etc. is necessary.

Urban forest area in South Korea has been increased up to 20.8% of national land as of 2007 by the mergence of municipalities and counties. The rate of park and green tract among urban forest averages out to about 4% nationally but the Capital, Seoul, almost 105% level, not easy to split the two. Park and green has positive management system because of its infrastructure attribute and relevant security obligation standard while urban forest left alone with no such concerns. The most important reason of the negligence comes from institutional inertia although it is possible to be managed functionally by forest laws as like forests of park, landscape, wind and noise protection, and timber product. As a results, it reaches below than 92.64% of the national average level of the timber stockpile especially in the metropolitan areas and loses broad acres rapidly due to the easy conversion system to the urban land usage. Therefore, there must be required some alternative methodologies to conserve and foster it. The paper proposes the four urban forest management types and their control methods. The four types divide into conservation, foster, development, and reservation ones. Also it suggests the five furtherance tract types with the combination among the four earlier types, optionally having one of the six aim climaxes and recommends the standardization of operation design. The total green quantity index of urban forest also suggested by the weight method according to location and DBH class. The case study of the suggested model was executed on the Daejon Metropolitan area and its index calculated as 110.4% level compared with the acreage.

This is a study on how to create an ecological arboretum that would promote biodiversity by creating wild animal habitats in terms of using large-scale remnants in urban areas and that would serve as a field for environment education based on its locational feature of being an urban area and its accessibility. This study is significant in a sense that this is the first arboretum to be created in urban area. However, it has a couple of limitations and they are as follows. First, since an arboretum creation plan is a mid/long-term plan, it is difficult to verify the biodiversity promotion effect of the application of habitats and creation techniques. Second, as the space was created by considering ecological features and utilizing natural prototype, the diversity of forest trees in here is lower than that of a traditional arboretum.
