This research was conducted to investigate the impact of viewing scenery and walking in the urban forest on physiological relaxation of humans. The experiment was conducted in Hanbat Arboretum located in Daejeon, and the control experiment was conducted in front of Daejeon City Hall. The subjects that participated in the experiment comprised 24 Korean male university students in their 20s (average age, $21.1{\pm}2.5years$), participated in the experiment as the subject, and these subjects were classified into three groups divided into three locations such as the pine forest in Arboretum, the pond in Arboretum, and the city. The subjects sat down and viewed scenery for 10 min, and they then walked for 15 min. Further, physiological changes were measured using indicators such as heart rate variability (HRV), blood pressure, and pulse rate. As a result, when subjects viewed scenery and walked in the urban forest, a statistically significant increase in the high frequency (HF) power of HRV and decrease in systolic pressure was observed compared with when subjects viewed scenery and walked in the city. Through this research, it was found that activities like viewing scenery or walking in Arboretum of the city are effective in increasing the physiological relaxation of the city residents.

Totally 91 strains of wild yeasts were isolated from the humus rich soil in the Bogyong city park of Daejeon city, Korea. Majority of the strains belonged to Cryptococcus spp., which included 11 strains of Cryptococcus aureus. Among them, Kwoniella mangroviensis JSS0500, Candida corydalis JSS0501, Candida bombi JSS0503, Candida multigemmis JSS0504, Cryptococcus dimennae JSS0506, Cryptococcus saitoi JSS0507, Cryptococcus victoriae JSS0508, Metschnikowia pulcherrima JSS0502, Papiliotrema aurea JSS0505, Debaryomyces vanrijia JSS0509, Occultifur externus JSS0510, Filobasidium floriforme JSS0511 and Yamadazyma scolyti JSS0512 represented newly recorded yeast strains in Korea, and their microbiological characteristics were investigated. All of these unrecorded yeasts showed oval shape and also formed ascospores and pseudomycelia, except for Kwoniella mangroviensis JSS0500, Candida bombi JSS0503, and Metschnikowia pulcherrima JSS0502. Seven strains including Candida corydalis JSS0501 grew in vitamin-free medium, and 4 of the wild yeasts including Cryptococcus victoriae JSS0508 were halotolerant, i.e., capable of growing in 10% NaCl-containing yeast extract-peptone-dextrose (YPD) broth. Debaryomyces vanrijia JSS0509 was found to be a thermophilic yeast that grew at $37^{\circ}C$.

Recently, industrial locations have faced changing trends under the influence of emerging industries as well as advanced new technologies. So the purpose of this study is to analyze the spatial distribution and locational factors of biotechnology industry formed around the Seoul Metropolitan area and Daejeon city, both of which are centers of Korean biotechnology industry, and is also to identifytheir locational characteristics. Major results of this study can be outlined as follows: First, from the mid 1990' s to 2000, Korean biotechnology industry has rapidly developed owing to central and local governmental support policies and systems as well as changes in domestic economic environment due to Korean financial crisis. Secondly, it was found that spatial distribution of Korean biotechnology industry converged on the Seoul Metropolitan area till 1990, but shifted from there to Daejeon and Chungcheong area from 1990 to 2000. Particularly after 2000, positive local governmental efforts to attract biotechnology players have driven the spatial distribution of biotechnology industry to shift from Seoul Metropolitan area and Daejeon or adjacent area gradually to other profitable locations. In terms of locational factors, it was found that the locations of Korean biotechnology industry converged primarily on university or college campus and biotechnology venture center, particularly on locations adjacent to superhighway or expressway. Locational factors varied depending on region, industrial type and business growth phase. Therefore, it is advisable that our central and local government should make and implement practical and useful policies in favor of biotechnology business depending on region, industrial type, business growth phase, rather than depending on uniform locational policies.

Sixty natural springs and wells used as community facilities for drinking water are developed along mountain climbing way of suburban area and residential area in Daejeon City. In this study, the seasonal variation of their water quality and hydrochemical characteristics were investigated. Some natural springs are vulnerable to bacilli contamination because of their short residence time and shallow circulation in subsurface environment. The waters show hydrochemical types of Ca-HCO$_3$ and Na-HCO$_3$, and are characterized by low electrical conductance and weak acidic pH.

By the rapid technological advance and social needs, demand of Multi Function Facility is on the increase. The multiplex is an alternative of them. In case of fire, special function of facility nay result in terrible accident. Therefore, literature and regulations survey on the multiplex were enforced, Multiplex facilities in Daejeon City were surveyed, and reformation of regulation and structural system were suggested in this study.

According to opening the domestic existing lines and High-Speed Lines(HSL) depending on each section and phase-in, there were constructed in railway over state-of-the-art radio communication networks. Therefore, there have been 3 wireless communication networks in domestic railways in accordance with running sections as like VHF, TRS-ASTRO and TRS-TETRA. For instance, the VHF networks were constructed in exsiting lines and TRS-ASTRO were Kyungbu HSL phase-1 except Seoul-Kwangmyung section, downtown in Daejeon City and that of Daegu City. And it was constructed in DongDaegu-Busan section of Kyungbu HSL phase-2, Osong-Kwangju section of Honam HSL phase-1 and would be done in Kwangju-Mokpo of Hanam HSL phase-2 and Soosu-Pyungtaek of Metropolitan Area Line by TRS-TETRA. In this paper, we described some important problems of radio communication management and investigated current state of radio communication for railways. Moreover, we presented the necessity of integrated radio networks for domestic railways.

The increasing elderly population and elderly household are very serious problem in our time. They are weaker physically and mentally than they were in the past. There is hardly a house with floor and facility design for them. So the purpose of this study is to find the need of the elderly for the living condition in Daejeon city. Their needs of interior are invested by questionnaire for elderly over 65 years old. Remarkably, they are not unsatisfied the present condition in spite that it is not agreeable in fact. The informations, for example the equipments and remodeling, to make their life more conveniently are not noticed to them fully. And they point up the emergency bell, the handiness of controlling windows, getting rid of the difference of thresholds, non-slip materials, grab bars around the a chamber pot and the expediency of controlling a tap as important things to select a house. First of all the sensitive considerations to make their living comfortable by designers are needed absolutely and the publicity work to notice the beneficial inform for them is needed.

This study aims at analyzing the structure of the regional industries in Daejeon, including Choongchung area and the measurement of Regional Innovation Ability Index. The study also investigates the environment of the regional innovation activities in terms of Regional Location Quotient Index. The study mainly focuses on the estimation of four types of innovation ability indexes, i.e., human resource, knowledge creation, knowledge transfer and application, and innovation supporting finance output market. The findings indicate that Daejeon showed the highest index 2.977, and Seoul recorded 2.650 as the second rank. The indexes of Choongnam and Choongbuk were 2.034 and 2.082, respectively, which reached to 76%~78% of that of Seoul. The indexes of the other cities accounted for only 50%~60% of that of Deajeon city. This study concludes that there is a regional difference particularly in the knowledge creation area.
