  • The forest vegetation in Daedeok Science Town were classified as second forest vegetation and afforestation vegetation. The second forest vegetation was classified into two communities such as Pinus densiflora community and Quercus acutissima community. Also, the afforestation vegetation was classified again as Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community. In this study area, we found total 217 taxa. The average species of appearance in Pinus densiflora community, Quercus acutissima community, Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community were 21, 20, 20, 21, 21, and 18, respectively. There was no difference in appearance species between second forest and afforestation vegetation. We found total 12 naturalized plants taxa of Commelina communis, Phytolacca americana, Erigeron annuus, and Ailanthus altissima in the plots and total 19 naturalized plants taxa of Dactylis glomerata, Bidens frondosa, Xanthium strumarium, and Soianum nigrum in the climbing roads and forest circumferences. And so, we found total 31 naturalized plants taxa in this study area.

  • The growth of Ti on Si(111)-$7{\times}7$ and the formation of epitaxial C54 $TiSi_2$ were investigated by using reflection high energy electron diffraction(RHEED) and high resolution transmission electron microscopy(HRTEM). Polycrystalline Ti layer is grown on the amorphous Ti-Si interlayer which is formed at the Ti/Si interface by Ti deposition on Si(111)-$7{\times}7$ at room temperature (RT). HRTEM lattice image and transmission electron diffraction(TED) showed that epitaxial C54 $TiSi_2$ grown on Si substrate with 160 ML of Ti on Si(111)-$7{\times}7$ surface at RT, followed by annealing at $750^{\circ}C$ for 10 min in UHV. Thin single crystal Si overlayer with [111] direction is grown on $TiSi_2$ surface when $TiSi_2$/Si(111) is annealed at ${\sim}900^{\circ}C$ in UHV, which was confirmed by Si(111)-$7{\times}7$ superstructure.

  • DO-stat fed-batch cultures of Agaricus blazei were carried out using various feeding solutions, for the production of mycelial biomass and exopolysaccharides (EPS). It was observed to be more effective to use a feeding solution containing both carbon and nitrogen sources than that containing only carbon source. The best result was obtained when a feeding solution containing 450 g/l glucose, 60 g/l yeast extract, 30 g/l soytone peptone was used. The maxium mycelial biomass and EPS concentrations were 36.5 g/l and 10.9 g/l, respectively, at 100 hours of cultivation. The mycelial and EPS productivities were 0.37 g/l-h and 0.11 g/l-h, respectively. As compared with the batch culture, the mycelial biomass concentration and its productivity were 6.0- and 2.2-folds increased, respectively. The EPS concentration and its productivity were increased by 4.7 times and 1.8 times, respectively.

  • In Korea, most of the locations of the cemeteries and burial vault are in forest lands. The utilization of forest land for this particular purpose is very inefficent and considered to be a serious problem. National government (Forest Service), local governments (Incheon city), and religious corporation (eunhoe Temple) are creating new burial methods to solve the inefficiency in forest utilization. In this study, awareness of Koreans and Japaneses on tree burial problems were compared. Based from the results of the survey, more than 80% of the respondents are aware of the problems. However, the burial culture in Korea still has many problems. Operation and management of tree burial is not being done by experts and sufficient information regarding to this type of burial still needs to developed. To solve these problems, eco-friendly burial, which is considered as new funeral culture, is now being created. In the case of Ichinoseki City in Iwate prefecture in Japan, improving the residential environment greatly affected the tree burial practices. This town was chosen for this study due to its characteristics of being a tourism area which greatly affecting the economy of this town. Another study site of this study was located in Sangju city. The changing social environement and the perception of the people regarding on the services being provided to the people were examined thru questionnaire survey. Specifically, this study analyzed the practices and beliefs of the people regarding the tree burial culture.

  • This study aimed to establish a systematic and comprehensive operational plan for the library to be constructed in the Gwacheon Knowledge Information Town. To achieve this, a survey on the demand for library operations was conducted among actual users of the Gwacheon City Public Library, and plans for the library collection development, user services, and methods to revitalize use were formulated based on the survey results. The findings are as follows. First, the library's construction/space analysis results suggest the need for a multifunctional cultural space accessible to everyone, serving as both a relaxation area and venue for a free information exchange and communication, allowing for a certain level of noise to facilitate an open atmosphere for users. Second, the analysis of the preferred types and forms of library materials revealed that printed materials ranked first, followed by web resources in the second place, and e-books/e-journals in the third. Additionally, there was a high preference for subjects such as literature and history. Third, a high preference was observed for cultural and arts programs, indicating the need for the future Gwacheon Knowledge Information Town Library to strengthen and implement programs focusing on cultural and artistic themes.

  • To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

  • This study performed recognition and preference tests on hometown foods given to University students in NaePo province, which is in the northwest area of Chungnam, Korea. The results indicated that female students and people who majored in food science were less interested in hometown foods than male students or who are not majors in food science. Moreover, they preferred Korean-style foods to food from other countries. Mass media has aroused interest in hometown foods. However, hometown foods require standard recipes certain levers of autonomy for the population. Hometown foods are valuable and should be handed down the next generation through publicity. For example, Kkotgetang(blue crab soup) was the best known hometown foods followed by kkotgegang(fermented blue crab with sauce), saeujeot(salted and fermented shrimp), eorigul jeot(salted and fermented oyster with red pepper) in that orders. The most preferred food was kkokgetang(blue crab soup) followed by kkotgegang(fermented blue crab with sauce).

  • A deterministic tuberculosis model for theoretically assessing the potential impact of the combined effects of case detection in the presence of treatment is formulated. The qualitative features of its equilibria are analyzed and it is found that the disease-free equilibrium may not be globally asymptotically stable when the reproduction number is less than unity. This disease threshold number is further used to assess the impact of active TB case finding alone and in conjunction with treatment. A critical threshold parameter ${\Theta}$ say for which case detection will have a positive impact is derived. Using the Centre Manifold theory, the model may exhibit the phenomenon of backward bifurcation (coexistence of a locally stable endemic equilibrium with a stable disease-free equilibrium) when the reproduction number is less than unity. It is shown that the possibility of backward bifurcation occurring decreases with increase case detection. Graphical representations suggest that increase in case finding accompanied by treatment of detected TB cases, result in a marked decrease of TB cases (both latent and active TB).
