This study is to examine the characteristics of fabrics in Koryo dynasty by reviewing the fabrics for enshrining oblations inside a buddhist statue in MoonSoo temple, which are currently possessed in SooDuk temple. The research results follows : The fabrics are 33 pieces in total : 28 Pieces of normal fabrics, 5 pieces of fabrics that is used for covering the five grains, and others like variegated silk threads. Out of 33 pieces of fabrics are there 31 pieces of silk and 2 pieces of ramie. The tabby fabrics, which have the most pieces among the fabrics, are 11 pieces in total. There are 1 piece of designed tabby fabri. whose patterns are expressed by dyeing. as well as non-designed tabby fabric. The twill fabrics are 8 pieces in total. Its patterns are mainly the type that small patterns are consecutively reiterated. And they have various patterns including plant patterns, such as lotus pattern, flower pattern. etc., animal patterns such as dragon pattern. etc., geometric patterns. such as turtoise-shell pattern. swastika, etc. The leno and gauze fabrics are 1 piece of 4-end complex designed-gauze and 1 piece of gill gauze. The compound woven fabrics are 2 pieces of brocaded gauze and 3 pieces of brocaded twill. Brocaded gauze is a kind of brocaded fabrics and is made by adding a gold thread between wefts of already weaved gauze. The figured fabrics are 1 piece of tabby fabric, 6 pieces of twill fabrics, 4 pieces of leno and gauze fabrics, and 5 pieces of compound woven fabrics. All of them are 16 pieces out of all 33 pieces and amount to almost 50%. Single-patterned fabrics, that is one pattern is expressed individually, are much more than any others. Plant patterns are the ones that are used the most.

Thermodynamic and economic analyses of various types of gas turbine combined cycle power plants have been performed to establish criteria for optimization of power plants. The concept of efficiency, in terms of the difference in energy levels of electricity and heat, was introduced. The efficiency of power and heat generation by power plants with other purposes was estimated, and power generation costs were figured out for various types of combined heat and power plants(i.e., fired and unfired, condensing and non-condensing modes, single or double pressure HRSG).

Objective : TM-MC was constructed to provide information on the chemical compounds of medicinal plant materials which were listed in Korean, Chinese, and Japanese pharmacopoeias. The aim of this study was to compare of the chemical compounds of TM-MC with those of domestic pharmacopoeias.Methods : First of all, TM-MC was updated on medicinal materials and chemical compounds which were extracted from articles up to the PubMed identifier of 26 millions. After searching for medicinal plant materials with information on their major compounds in Korean pharmacopoeias, we identified that the information on medicinal materials and chemical compounds were also existed in TM-MC. Then, we figured out how much the compounds have been studied by counting the number of articles for those compounds in TM-MC.Results : Information on 9 medicinal materials and about 1,700 compounds was newly added to TM-MC after manually curating 645 articles. Korean pharmacopoeias contained a total of 91compounds from 53 medicinal plant materials, while TM-MC provided information on the 89 compounds from the 53 medicinal materials in Korean pharmacopoeias. The compounds stated in Korean pharmacopoeias has been much studied by comparison with other compounds of each medicinal material in TM-MC.Conclusion : Most of chemical compounds stated in Korean pharmacopoeias were also listed in TM-MC, excluding two compounds. Thus, we concluded that information in TM-MC is mostly consistent with that of Korean pharmacopoeias. In the future, we will periodically update TM-MC with articles added to the MEDLINE.

Agromonia pilosa Ledeb. has been used as a medicinal plant in traditional folk remedy. There are few reports on classification, physiology, ecology and morphological studies of Agromonia pilosa L. in Korea. Therefore, advanced approaches on study and development with this plant would be done urgently. Present stndy was carried out to gain basic information on genetic resources and variation with collected domestic landraces through RAPD analysis in Agromonia pilosa L. Forty two collections of Agromonia pilosa L. from nation-wide area including USA one were analyzed by RAPD test. Molecular marker size by amplified DNA band pattern ranged from 300 to 2,100bp. Among the collection, two landraces of Hadong and Cheonghak-dong showed close relation in genetic similarity. Minimum and maximum value by matrix of 1-F among 26 collected landraces were figured out as 0.365 and 0.827 showing mean value for 0.624, respectively. Those landraces were classified into two groups with cluster analysis by Nei and Li's formula from RAPD-analyzed values, and considerable genetic differences were recognized between two groups.

The ecosystem in the Gwangju Stream has taken a wide range of disturbance such as the discharging water of sewage treatment plant, the lake water and the river water from different water system over the past decade. This study was figured out some significant influence factors by analyzing the relationship between biotic and abiotic factors in the urban stream. Abiotic components included 15 water quality variables which were measured in five sampling sites along the stream from October 2014 to July 2015, whereas the benthic macroinvertebrates found in those sites were used to estimate various biotic indices representing the ecological status of the community. The results of correlation analyses indicated that abiotic factors by human activities affected on the inhabitation of benthic macroinvertebrates more than biotic factors. The results of cluster analyses and ANOVA tests also showed that biotic and abiotic characteristics were clearly different in season. The main influence factors of cluster analysis by sites were $NH_3-N$, EPT(I) and DO. It was considered that more various statistical analyses would be necessary to find some different relationships and influence factors between biotic and abiotic variables in the urban stream.

FT is one of the major floral activator in plant flowering. FT determines the changing point of time from vegetative stage to reproductive stage. To understand the role of FT homologs in short-day plant soybean, we identified 10 soybean FT homologous genes and named GmFTs. We figured out that 10 GmFT genes were further categorized into three subclades through phylogenetic analysis. Expression analysis of GmFT genes indicated that they might have different functions in photoperiod-dependent soybean flowering. Most of GmFTs, for example, GmFT2a, GmFT2b, GmFT5a and GmFT6 mainly expressed in soybean leaves at short-day condition. However, interestingly GmFT1a and GmFT4 represented opposite expression pattern to other GmFTs. Arabidopsis transgenic plants overexpressing GmFT2a and GmFT5a exhibited extremely early flowering. In contrast, overexpression of GmFT4 delayed flowering of Arabidopsis transgenic plants. The results suggest that GmFT4 has antagonistic role to other GmFTs in soybean flowering. Interestingly, mRNA level of GmFT2a is higher in early flowering soybean accessions than in late flowering ones. Moreover, the highest point of mRNA level of GmFT2a showed the positive correlation with the timing of flowering of soybean accessions. But that of GmFT4 showed opposite pattern. Here, we report that soybean FT homologs might acquire different functions in photoperiod-dependent flowering through the functional diversification during evolution.

Research was initiated to find out acid drainage neutralizing techniques for ecological vegetative growth on the acid drainage slope. Four different acid drainage neutralizing techniques [no treatment, limestone layer treatment, phosphate treatment, and limestone layer + phosphate treatment] were treated on the acid drainage slope. There was a significant difference observed in treated acid neutralizing techniques for acidity, surface coverage rate, death rate and plant root status. Treated acid neutralizing techniques were effective for neutralizing acidity and vegetative growth in order of [first: limestone layer + phosphate treatment, second: phosphate treatment, third: limestone layer treatment and fourth: no treatment]. The limestone layer and the phosphate treatments were effective for neutralizing acidity and vegetative growth, respectively. However, the phosphate treatment was more effective compared to the limestone layer treatment on the acid drainage slope. We figured out that the phosphate treatment is more effective for neutralizing acidity and vegetative growth because of coating effect of sulfides.

The research was conducted to find optimal habitats of warm-temperate evergreen broad-leaved trees, and to investigate climate factors to determine their distribution using classification tree (CT) analysis. The warm-temperate evergreen broad-leaved trees model (EG-model) constructed by CT analysis showed that Mean minimum temperature of the coldest month (TMC) is a major climate factor in determining distribution of warm-temperate evergreen broad-leaved trees. The areas above the $-5.95^{\circ}C$ of TMC revealed the optimal habitats of the trees. The coldest month mean temperature (CMT) equitable to $-5.95^{\circ}C$ of TMC is $-1.7^{\circ}C$, which is lower than $-1^{\circ}C$ of CMT of warm-temperate evergreen broad-leaved trees. Suitable habitats were defined for warm-temperate evergreen broad-leaved trees in Korea. These habitats were classified into two areas according to the value of TMC. One area with more than$-5.95^{\circ}C$ of TMC was favorable to trees if the summer precipitation (PRS) is above 826.5mm; the other one with less than $-5.95^{\circ}C$ of TMC was favorable if PRS is above 1219mm. These favorable conditions of habitats were similar to those of warm-temperate evergreen broad-leaved trees in Japan. We figured out from these results that distribution of warm-temperate evergreen broad-leaved trees were expanded to inland areas of southern parts of Korean peninsula, and ares with the higher latitude. Finally, the northern limits of warm-temperate evergreen broad-leaved trees might be adjusted accordingly.
