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.

It constitutes a very important preliminary step to analyze how city image is assessed in order to determine the direction towards a desirable city image in planning on an urban landscape for future city image. This study aims to quantify the recognition and evaluation of a city image on the part of citizens, using multidimensional scaling and correspondence analysis. Furthermore, this study hopes to contribute to the quantified policy-making for improving city image by understanding how professionals and civil servants in the related field tend to recognize such image. The results from the study are as follow: 1. The image of Daejon City tends to be assessed strongly in the light of its history, dynamics, and size. While the City is recognized as new and changing in general, the civil servants consider the city as modest, and the professionals as mediocre. Therefore, the City should strive to conceive its own unique identity, which would lessen the current image of modest and mediocre. 2. Gap river, Dunsan New Town, and the Daeduk Reseach Complex turn out to be the symbolic representative venues of Daejon City, inspiring the city’s image. In contrast, Yoosung Springs, the original town, and the Expo Park do not fit the image of the City. The need to renovate these places presents itself. 3. As for the questions using “like” and “not-like”, citizens and professionals show the tendency of not liking the city’s image, whereas civil servants like it. It follows that the City needs to highlight its “modern and high-technological” image, illuminated by Dunsan New Town and Daeduk Reseach Complex. 4. An image positioning drawn from a correspondence analysis shows that the City of Daejeon can be classified as an administrative and horizontal city. As opposed to the prior simplistic analyses of city image, this study attempts to diagnose it accurately, so as to help with the gearing towards city images in the future.

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%). Finally, I propose that the best strategy for men with low fashion consciousness is to upgrade salesmen' coordination technic and fabric knowledge, and store management with story attracting customers.

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.

Objectives: This study was performed to determine the mental health of high school students, and specifically that of children with no siblings in urban areas, and we aimed at revealing the various potential influences of different psycho-social factors Methods: The participants were, 514 high school students who were the 1st- to 3rd-graders in Daejon City; they were, given self-administered questionnaires that required no signature during the period of March through June 2005. The analyzed items included the general character of the subjects, the symptoms of stress and depression for mental health, self-esteem as a psychological component, anxiety, dependent behavioral traits and, social support of family members and friends. Results: The study results suggested that the group of urban high school children with no siblings had a higher tendency for stress and depression than did the urban high school children with siblings. The mental health and psychosocial factors were found to be influenced by friends, a sense of satisfaction at school and home life, and emotional support as well. Conclusions: In conclusion, emotional support by the family members can improve mental health by reducing anxiety, stress and depression.

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.
