The architecture reflects geographical characteristics such as geographical environments and climate, it has the characteristics and cultural characteristics of the region that has been constructed. Hansen Village constructed in Period of Japanese Occupation at 'Sorok-Island' in Go-heung, Jeollanam-do was also based on this point. The village, which is a ward of Sorok-Island Province, consists of a village in which patients are self-sufficient in economic and social activities, unlike the modern hospital systems where patients and treatments are concentrated in a single room. Additionally, the facilities for patient acceptance were gradually expanded, with limited interaction with external. Sorok-island shows the expansion of the village center where the new village is formed with the increase of the number of the early adopters in the 1910s and the accommodation facility is built, and it gradually increases the necessary space by opening and repairing the existing facilities by the 1990s Change. In addition, the spatial composition of the village can be divided into three types : decentralized, centralized and single-shift ; it has the same causal relationship as the village's formation. The purpose of this study is identifying the uniqueness of Sorok-Island by analyzing the correlation between the formation of a village to accommodate Hansen Patients in Sorok-Island and the spatial Component Factor.

A new biopolymer YU-122 from Metarrhizium anisopliae (Metschn.) Sorok consisting of glucose and galactose was tested for its physical properties and flow behavior characteristics. Xanthan gum showed slightly higher viscosity than biopolymer YU-122. Viscosity of biopolymer YU-122 at various pHs and temperatures was also tested. The viscosity of biopolymer YU-122 was very stable up to pH 11 and $60^{\circ}C$, indicating that it has a great possibility for the application such as food additives, emulsifier, and drug release agents. Flow behavior index (n) from Power Law equation is 0.173. Biopolymer YU-122 solution was a pseudoplastic non-Newtonian fluid, which indicated that it had one or more side chains. When biopolymer YU-122 was used as a emulsifier, it stabilized the emulsion up to 120 hours, which was much better than xanthan gum. The biopolymer YU-122 could form an excellent but less clear film compared with xanthan and pullulan.

Purpose: The purpose of this study was to identify life experiences of Korean patients with Hansen's disease (leprosy). Methods: For this study, 5 participants from Sorok Island Hospital were purposively chosen. Data were collected through in-depth individual interviews from June to July 2014. Data analysis method was based on Colaizzi's approach. Results: The study results showed that experiences of patients with Hansen's disease consisted of 14 themes and six theme clusters: 1) Bad disease approaching as fate; 2) Family breakup and far from the village; 3) New life in Sorok Island Hospital; 4) Treatment of Hansen's disease and disability; 5) Life in the disease community; 6) Comfort and hope of life. Conclusion: The findings of this study indicate that health care professionals should pay attention to patients with Hansen's disease not only to reduce their physical and psychological suffering, but also to help the community and public culture to reduce the social stigma surrounding this disease and causing suffering for the patients. The results of the present study can help us to have a better understanding of various aspects of patients' lived experiences.

To produce biopolymer, Metarrhizium anisopliae (Metschn.) Sorok was cultured in a medium containing glucose 1.0%, sucrose 2.0% , soluble starch 1.0%, yeast extract 0.5%, polypeptone 0.05%, K$_{2}$HPO$_{4}$ 0.1% MgSO$_{4}$ $\CDOT $ 7H$_{2}$O 0.02%. The culture broth was centrifuged and the polymer was harvested by adding methanol to the culture supermatant. When three times of methanol was added, the polymer was coagulated and precipitated. Then it was further purified through successive SK-1B, SA-20P, HP-20 column chromatographies. This polymer was designated as Biopolymer YU-122.C:H ratio of this Biopolmer YU-122 was 1:2 and small amount of N is detected by CHN analyzer. Glucose and glactose are main components of this polymer. Average molecular weight of this biopolymer was 1.7%$\times $10$^{6}$ by Sepharose 4B gel permeation chromatography. Optimal condition for biopolymer production was investigated. When 5% of mannitol was used as a carbon source, and polypepton as a N source, highest productivity of biopolymer was achieved. C/N ratio as nutrient was also a major factor in polymer production and its optimal ratio was 3.

To improve the preservation of Kimchi, we isolated Lactobacillus plantarum lytic enzyme-producing strain from soil, and the enzyme was purified and characterized. From the observation of cultural and morpho- logical characteristics, the isolated strain was identified as Metarrisium anisopliae (Metschn.) Sorok. The enzyme was purified to 75-folds with 40% yields through affinity adsorption and CM-Sephadex C-50 column chromatog- raphy. The optimum pH and temperature for lytic activity are 4.0 and 40$\circ$C, respectively, and the enzyme acitvity is stable between pH 3.0 and 9.0, and up to 50$\circ$C. The enzyme is a monomeric protein with molecular weight of 40,000 daltons by SDS-PAGE and gel filtration. The enzyme is endopeptidase which breaks the peptide linkage of Lactobacillus plantarum peptidoglycan. The lytic action spectra confirmed that Leuconostoc mesenteroides, a useful strain for the fermentation of Kimchi, is not lysed by the enzyme. The enzyme activity is inhibited by N-bromosuccinimide (NBS), which probably indicates the involvement of tryptophan residue in active site of the enzyme, and also inhibited by Ag$^{+}$. The amino acid composition analysis showed that the enzyme contains more acidic amino acids than basic ones, and composition of alanine, glycine, proline and tyrosines was very high.

A viral disease causing severe mosaic, necrotic, and yellow symptoms on Vigna angularis var. nipponensis was prevalent around Suwon area in Korea. The causal virus was characterized as Cucumber mosaic virus (CMV) on the basis of biological and nucleotide sequence properties of RNAs 1, 2 and 3 and named as CMV-wVa. CMV-wVa isolate caused mosaic symptoms on indicator plants, Nicotiana tabacum cv. Xanthi-nc, Petunia hybrida, and Cucumis sativus. Strikingly, CMV-wVa induced severe mosaic and malformation on Cucurbita pepo, and Solanum lycopersicum. Moreover, it caused necrotic or mosaic symptoms on V. angularis and V. radiate of Fabaceae. Symptoms of necrotic local or pin point were observed on inoculated leaves of V. unguiculata, Vicia fava, Pisum sativum and Phaseolus vulgaris. However, CMV-wVa isolate failed to infect in Glycine max cvs. 'Sorok', 'Sodam' and 'Somyeong'. To assess genetic variation between CMV-wVa and the other known CMV isolates, phylogenetic analysis using 16 complete nucleotide sequences of CMV RNA1, RNA2, and RNA3 including CMV-wVa was performed. CMV-wVa was more closely related to CMV isolates belonging to CMV subgroup I showing about 85.1-100% nucleotide sequences identity to those of subgroup I isolates. This is the first report of CMV as the causal virus infecting wild Vigna angularis var. nipponensis in Korea.

Lichen-forming (LFF) or lichenicolous fungi (LCF) were isolated from the lichens collected at‘Backwoon’mountain area,‘Chiri’mountain area and‘Sorok’island in the southern regions of Korea and were screened for antagonistic efficacy against several phyto-pathogenic fungi. Symbiotic algae-free LFF and LCF were isolated by the following methods: I) discharged spores (ascospores), II) macerated thallus suspension and III) direct use of thallus fragments. Among 58 isolates obtained from 34 lichens, 8 isolates showed antifungal activity against Rhizoctonia solani. Antifungal activities of the strongest antagonistic isolate (LB9810) originated from the thallus of Parmelia quercina lichen were evaluated against 15 phyto-pathogenic fungi. When crude methanol extract of mycelia of the LB8910 isolate was employed at the rate of 0.5% (v/w), fungal growth of Magnaporthe grisea and Rhizoctonia solani was severly and Rhizoctonia solani was severly inhibited as much as approximately 60% compared to control. Growth of various food-borne same extract. The extract was successively partitioned with n-hexane, ethyl acetate and n-butanol. n-Hexane fraction displayed the strongest antifungal activities against R. solani. The LB9810 isolate was finally identified as Fusarium equiseti (Corda) Sacc., which has not been reported as LFF or LCF yet. Therefore, it is very likely that F. equiseti isolated it the study was originated from the contaminants associated with thallus fragments rather than from LFF or LCF.
