The main contents of revision of the rural landscape planning according to Landscape Law discussed in this study show that the urban landscape and rural landscape have a propulsion system which integrate them into the national landscape and manages through the landscape planning. However, management and conservation reflecting the fundamental difference between urban and rural areas are needed. Planning the landscape by generalizing the size of the population, administrative district, the surface area does not meet the ultimate purpose of the Landscape Law that tries to establish differentiated local landscapes. Therefore, the association of professionals who can support and establish a propulsion system for landscape planning with the consideration of regional characteristics. For the urban landscape, the landscape committee is fulfilling the role, but none is available for the rural areas. This study is mostly based on previous literatures, however, in the future, it is desirable to have selected pilot areas for different landscape types and review problems that may occur during the application and process, in order to establish the landscape guidelines for the rural landscape plan.

An experimental study was performed for the preparation of living skin-equivalent by the using collagen gel contraction with human fibroblasts as neodermls and cultured human keratinocytes as neoderm is . The results were as follows ; 1) The rate of collagen gel contraction was dependent on the number of fibroblasts into the lattice and collagen contraction was progressed according to the increment of the number of the cells. 2) The rate of collagen gel contraction was progressed according to the decrement of the contraction of the collagen. 3) The rate of gel contraction was progressed according to the increment of serum concentration in the fixed concentration of the fibroblasts and collagen. 4) The lattice contraction was decreased according to the increment of the population doublings of the fibroblasts. 5) Macroscopically, the artificial dermis was gray white in color and tissue-like consistency and elas- ticity. 6) Microscopically, three dimensionally contracted artificial dermis showed more dense fibroblasts and its newly formed collagen fibrils in the matrix than one dimensionally contracted one. 7) Finally prepared skin-equivalent showed good attachment of living stratified keratinocytes to the dermal equivalent microscopically. It has been proposed that newly formed skin-equivalent is suitable for the graft of extensively and deeply burned patients. Shortening of the manufacturing period of skin-equivalent and development of conservation technique as a readily usable state are to be solved for our ongoing works.

Comprehensive information on genetic diversity and introgression is desirable for the design of rational breed improvement and conservation programs. Despite the concerns regarding the genetic introgression of Western pig breeds into the gene pool of the Korean native pig (KNP), the level of this admixture has not yet been quantified. In the present study, we genotyped 93 animals, representing four Western pig breeds and KNP, using the porcine SNP 60K BeadChip to assess their genetic diversity and to estimate the level of admixture among the breeds. Expected heterozygosity was the lowest in Berkshire (0.31) and highest in Landrace (0.42). Population differentiation ($F_{ST}$) estimates were significantly different (p<0.000), accounting for 27% of the variability among the breeds. The evidence of inbreeding observed in KNP (0.029) and Yorkshire (0.031) may result in deficient heterozygosity. Principal components one (PC1) and two (PC2) explained approximately 35.06% and 25.20% of the variation, respectively, and placed KNP somewhat proximal to the Western pig breeds (Berkshire and Landrace). When K = 2, KNP shared a substantial proportion of ancestry with Western breeds. Similarly, when K = 3, over 86% of the KNP individuals were in the same cluster with Berkshire and Landrace. The linkage disquilbrium (LD) values at $r^2_{0.3}$, the physical distance at which LD decays below a threshold of 0.3, ranged from 72.40 kb in Landrace to 85.86 kb in Yorkshire. Based on our structure analysis, a substantial level of admixture between Western and Korean native pig breeds was observed.

Taipei Water Management Office (TWMO) is one of the eleven district offices in Water Resource Agency. Water management is the top priority to be pursued both on daily management and long-term management at TWMO. There are five departments to perform a wide range of tasks in addition to water management. All management prescriptions are simply to provide sustainable clean water for about four millions population in Taipei. TWMO has gone through 16 years experience of development and implementation of GIS in water management. The objectives of this paper are to provide the major ingredients of successful and operational GIS for water management. The five departments at TWMO have performed tasks such as city planning, construction management, forest management, land use enforcement, soil and water conservation, water quality monitoring and protection, garbage collection, and sewage disposal management. Data base creation was one of the major jobs to be done. Update of data base has to be done on a daily basis. Computers, its peripheral, and software are essential for GIS developed at TWMO. Know-how and technical skill on computers and GIS for every technician are contributing significantly such that GIS can be implemented on most of jobs performed at TWMO. Implementations of GIS have been pursued by application modules on a task-oriented basis. Application modules are simple, easy to use, and menu driven with only Chinese. Web-based and mobile GIS are the new components that make water management at TWMO stay on the right course. To solve problems encountered in water management by GIS at TWMO can be easily and user-friendly may be the most important experience.

Mutation breeding by radiation is useful for improving various crop species. Up to now, a total of 170 soybean mutant varieties have been released in the world, which is the second most registered varieties after rice. Despite the economic importance of soybean, there have been no TRAP marker system studies on genetic relationships between/among mutant lines. To develop a strategy of Mutant Diversity Pool (MDP) conservation, a study on the genetic diversity of 210 soybean mutant lines (8 cultivars and 202 mutants) was performed through a TRAP analysis. Sixteen primer combinations amplified a total of 551 fragments. The highest (84.00%) and lowest (32.35%) polymorphism levels were obtained with primers MIR157B + Ga5 and B14G14B + Ga3, respectively. The mean PIC values 0.15 varied among the primer combination ranging from 0.07 in B14G14B + Sal2 to 0.23 in MIR157B + Sa4. Phylogenetic, principal component analysis (PCA) and structure analysis indicated that the 210 lines belong to four groups based on the 16 combination TRAP markers. AMOVA showed 21.0% and 79.0% variations among and within the population, respectively. Overall, the genetic similarity of each cultivar and its mutants were higher than within other mutant populations. Our results suggest that the TRAP marker system may be useful for assessing the genetic diversity among soybean mutants and help to improve our knowledge of soybean mutation breeding.

Little millet (Panicum sumatrense) is well known for its salt and drought stress tolerance and high nutritional value, but very limited knowledge of genetic variation and genomic information is available. This study was to develop highly polymorphic EST-SSR markers based on cross-species transferability of derived SSRs from switchgrass EST databases and characterize newly developed EST - SSRs to better understand the genetic diversity of collected 37 germplasm accessions of little millet. A total of 779 primer pairs were designed from the 22,961 EST sequences of switchgrass (Pancium virgatum), of which 48 EST - SSR markers were developed based on the trials of transferability of these primers in little millet. The EST - SSR amplicons showed reproducible single band polymorphism and produced a total of 160 alleles with an average of 3.3 alleles per locus in 37 accessions of little millet. T he average values of expected and observed heterozygosities were 0.266 and 0.123, respectively. T he polymorphic information content (PIC) values were observed in range of 0.026 to 0.549 with an average of 0.240. The genetic relatedness among the little millet accessions was evaluated by neighbor-joining dendrogram, which grouped all accessions into two distinct groups. The validation thus demonstrated the utility of the switchgrass EST - SSR markers in assessing genomic relationships in little millet. T he findings from this study could be useful for designing strategies for the identification of diverse germplasm for conservation and future molecular breeding programs for little millet.

First: The common points from "syllabus" period to that of "Course of study" are as follows: 1) with no introduction explained. the "Syllabus" or "Course of study" was made to be completed in accordance with the allotment of time (unit). 2) To teach how to rear animals and grow plants, and to make specimens with collected samples formed a great significant field of learning, which meant giving more emphasis on learning classification, life-centered education and basic field of learning than discipline-centered education. 3) The reason why the field of applied biology was emphasized on was that both periods had ideals in Common to educate persons more necessary and useful to the society than to major the pure academic field. 4) Both periods mainly dealt with problems of diseases, and physical health discussed all over the world in 1950's which accounts for necessity of the society to free from ignorance. Second; "The first curriculum period" and "the second one" are observed as follows: 1) The former took the unit (credit) system for the first time. It tried to lay down the conceptual hierarchy with "Biology I" and "II" divided, while "Biolgy I" is better systematized than "Biology II". 2) Discipline-centered education and structure fo knowledge are put more emphasis on especially in "the 2nd curriculum period". 3) And also in this period are included serious problems such as urgency of pollution, importance of nature conservation, population due to the development of industry. 'Third; With the recent curriculum laid down, experiments and teaching contents of subjects are put in harmony with each other and accordingly the process of Inquiry is laid emphasis on. Fourth; It is necessary to set up conceptual sequence and scope effectively in the curriculum.

The intensive habitats loss of natural organisms as a consequence of anthropogenic activities has lead to the use of alternative habitats for species conservation. We reviewed the current status of alternative habitats and suggest the improvement of alternative habitats. Most of alternative habitats regarded in this study are not following the pre-arranged consultation at environmental impact assessment. These alternative habitats are rendered useless due to the insufficient consideration of ecological characteristics of species and lack of detailed plans. A number of alternative habitats are influenced by disturbance such as environmental pollution and construction. Post-monitoring of alternative habitats are needed to estimate immigration rate of species. Post management is also needed to assess the status of population stability. Overall, low effectiveness of alternative habitats is presented in this study. According to the status survey, methods for improvement of alternative habitats are required such as detailed guidelines, establishment of post-monitoring system, improvement of habitat restoration techniques, and guidelines for management and operation of alternative habitats.
