This study had begun about the conflict between a lack of social adjustment and integration program for resident foreigners in Korea and a duplication of multicultural service in a specific area. This study was implemented through literature review and interview for analyses of the current status and problems of multicultural policy, subdivided into 3-stages model to reach the multiculturalism as multicultural policy process. The first stage suggested the unification of a channel for establishing a policies, reinforcing the functions of government ministries and the cooperation between the branches of the government. The second stage attempted to build the multicutural institutes network in a specific area unit, considering of the geographical and administrative environments. The third stage focused on the activities of individual organizations and proposed collaboration with library, school, support center for multi-cultural families, social service center, sport center, community center, and cultural facility. Additionally, 3-stages model emphasized on civic organization's role. This study was offered a meta-platform leaded by library community for sharing the information about planning and managing of multicutural programs and also mentioned significances for formulating multicutural policies. As a result, this study was presented and specified the 3-stages model to reach the multiculturalism, and verified the various considerations which have influenced the refinements of the multicultural policies as the demographic and geographical characteristics.

This study compares and analyzes the numbers and characteristics of Korea-related subjects included in the 2008 Japanese edition of the National Diet Library Subject Headings (NDLSH) and the $2^{nd}$ edition of the Chinese Classified Thesaurus(CCT). The analysis results show that 258 subjects, approximately twice as many as 137 subjects in CCT, were found in NDLSH. There are more pure subjects that exclude the references in CCT than in NDLSH. On the other hand, much more subjects are found in NDLSH in the event that personal names, corporate headings, and subjects combined with detailed headings are included. Meanwhile, more subjects are relatively engaged in the fields of politics, diplomacy, and military in CCT because CCT is characterized by socialism and by being a pro-North Korea. Moreover, the considerable numbers of subjects reflecting North Korea's viewpoint are included in CCT. NDLSH changed only recently the names of both South and North Korea into the "Republic of Korea" and the "Democratic People's Republic of Korea", respectively. On the other hand, CCT more frequently uses "Joseon" than "Korea", and the distinction between the names is unclear. CCT thoroughly supports the stance of the developed country, directly involved in the disputable subjects between two countries such as "Dokdo", "the East Sea", "Dumangang", and "Baekdusan". Both heading lists consider "Balhae" as part of Chinese history in CCT, which has ignored the position of Korea.

Norovirus (NV) with a variety of genotypes, a member of the family Caliciviridae, causes acute nonbacterial gastroenteritis in humans. We determined the nucleotide sequence of three open reading frames (ORFs) of a NV Korean strain and characterized the genetic relationship with others. The Korean strain designated Hu/NLV/Gunpo/2006/KO was isolated from the stool specimen of a 2-year-old female suffering from gastroenteritis. By performing reverse transcription and PCR amplification, three overlapping cDNAs were synthesized and used for direct sequencing. We found that like other NVs, this strain contains three ORFs: ORF1, 5,100 bp; ORF2, 1,647 bp; ORF3, 765 bp. Of 35 NVs, ORF1 had a level of genetic diversity lower than ORF2 and ORF3, of which the C-termini of the ORF2 and ORF3 showed a relatively high degree of genetic diversity. Phylogenetic analyses indicated that the Korean strain belonged to genogroup II, with Saitama U1, Gifu'96, Mc37, and Vietnam 026 being formed a single genetic cluster. The nucleotide sequence information of three ORFs of a NV Korean isolate will be useful not only for the development of a diagnostic tool and understanding of genetic relationship, but also provide important basic information for the functional analysis of their gene products.

This study was performed in order to analysis the landscape change and cause of scenic sites and surrounding environment is located in the Urban Residential Area since modern. The study was carried out using of field observations, literature review, cadaster map analysis from 1962 to 2010, and survey. It trace about Seongnagwon, Mapo Choi Sa-Young's old house, Seoul Seonjamdanji, Seoul Hanyang castle and those can be process of change per period. Also, it examine to original view of cultural assets and analysis about lots alteration with landscape alteration. Seongnagwon has original view which constructed the Songseokjeong and pond in 1954. Mapo Choi Sa-Young's old house has original view that move to Sungbook-dong and restore an old house. Seoul Seonjamdanji has it define original view that remained ruins by 1960's development. Seoul Hanyang castle has original view that stone fortress. Seongnagwon's landscape was changed by institutional factors. Mapo Choi Sa-Young house's landscape was changed by society economic factors. Seoul Seonjamdanji was changed by society economic and institutional factors. Seoul Hanyang castle was changed by technical and institutional factors. Generally cultural heritage of Sungbook-dong was changed by institutional and society economic factors. It is guessed that Seoul urban planning influenced Sungbook-dong development. The establishment of capitalistic economy system was backgrounds to it. Therefore, it expect to realized desirable landscape alteration that recognized potential value as culture resources.

To investigate the antagonistic inhibitory effects in a mixed culture between probiotics and various pathogenic microorganisms, 140 probiotics were identified using a 16 rRNA sequencing phylogenetic analysis method, and various probiotics strains were isolated from Korean kimchi from January to December 2016. The antagonistic inhibition test of a mixed culture of four probiotics (Enterococcus faecalis, Lactobacillus plantarum, Lactobacillus rhamnosus, and Lactobacillus reuteri) with excellent antimicrobial activity and six pathogenic microorganisms (Candida albicans, Salmonella Enteritidis, E. coli O157:H7, Shigella flexneri, Staphylococcus aureus, and Pseudomonas aeruginosa)showed that the growth of most probiotics strains increased normally after culture, but growth was inhibited almost completely in most pathogenic microorganisms, except for S. Enteritidis. This antagonistic inhibitory effect in vitro was attributed to the low pH of the lactic acid and organic acid produced during fermentation. As a result, four probiotics strains isolated from Korean Kimchi are very likely to be developed as therapeutic agents for female yeast infections and colon and skin care. In the future, these therapeutic agents will help improve public health related to probiotics.

To develop a new functional food material, edible crude saponin was isolated from soybean cake using HP-20 resin and its anticancer effect and immune-activity were investigated. The saponin significantly inhibited the growth of cancer cells such as A549, MCF-7 and SW480 at a concentration of 1,000 $\mu$g/mL. Morphological changes was observed in the AS49 cells surface treated with the saponin of 1,000 $\mu$g/mL concentration. The proliferation of mouse spleen cells treated with saponin was increased in a dose-dependent manner compared with untreated control cells until the concentration of 1 $\mu$g/mL but decreased at higher concentrations than that. The NO production in marcrophage cell lines (RAW 264.7) treated with saponin was increased in a dosedependent manner compared with untreated control cells.

The effect of Phellinus linteus methanol extract on the lipid metabolism in the liver of rat was investigated in this study. Rats were randomly divided into 6 groups including the control, $CCl_4$and high fat group plus sub-groups with Phellinus linteus methanol extract administration. Methanol extracts of Phellinus linteus were fed 50mg/kg B.W daily via drinking water. A 1.2mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total six times. The administration of $CCl_4$ increased total cholesterol, TG, LDL and LDL-phospholipid. However, the level of liver cholesterol and triglycerides were significantly decreased while HDL-cholesterol was increased by the extract feeding. The activities of GOT, GPT, AP and LDH were greatly enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ treatment deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract treatment reconstituted the damaged cytoplasm and stimulated mitochondriagenesis. From these results, it was suggested that Phellinus linteus can help to recover the damaged liver function and further may help to prevent senescence diseases such as fatty liver, hypertension and hyperlipidemia.

This study analyzes the male-female difference in self-employment rates in Korea using panel data constructed from the Economically Active Population Survey in 1999. Given that most studies on self-employment have focused on male self-employment and have not examined why self-employment rate is usually higher among males than females, this study certainly extends the existing literature on this subject This study consists of two parts. The first part deals with estimating self-employment rates for males and female within a Markov framework. The second part presents decomposition results of the male-female differential in self-employment rates. Major findings of the study are (1) self-employment rate is higher for males than females because entry into self-employment is larger but exit from self-employment is smaller for males than female, (2) higher entry probability for males is due to differences in coefficients of transition probability functions while lower exit probability for males is due to differences in characteristics, (3) a large part of male-female gap in self-employment rates results from differences in being a head of family, marital status and age between males and females.

Bacteriophages are viruses that exclusively infect bacterial cells, and lytic bacteriophages can be used as a safe alternative to antibiotics for the prevention and treatment of animal diseases. In this study, we attempted to isolate and characterize bacteriophages for Salmonella enterica serovar Gallinarum (Salmonella Gallinarum), the causative agent of fowl typhoid in chickens. Ten bacteriophages were isolated from samples of sewage from seven poultry slaughterhouses. One of these isolate, designated as $SG{\Phi}-YS$ SP and classified in the family Myoviridae, produced plaques with seven Salmonella Gallinarum strains. However, no plaques were produced with any of the Salmonella enterica serovar Enteritidis strains tested, suggesting that this bacteriophage is Salmonella Gallinarum specific. To assess the lytic ability of $SG{\Phi}-YS$ SP against Salmonella Gallinarum, bacterial growth rates following inoculation of the bacteriophage were compared with the control. The $SG{\Phi}-YS$ SP treatment, with a multiplicity of infection of 10, reduced the growth of Salmonella Gallinarum by 2.21 log cfu/mL at 6 h, and 2.13 log cfu/mL at 9 h, suggesting that this bacteriophage isolate could be used for the prevention or treatment of Salmonella Gallinarum infection in chickens.

Purpose: Installing a radial head prosthesis has developed into a reliable procedure to replace the native radial head for treating unreconstructible radial head fracture when this is associated with an unstable elbow or forearm. A variety of implants have been developed and these are now commercially available. This article reviews the literature related to the indications, the available implants and the surgical techniques of radial head replacement arthroplasty. Materials and Methods: The main indication for a metallic radial head prosthesis is a comminuted fracture that is not amenable to reconstruction, and particularly if it is associated with complex elbow injuries. Excision of the radial head should be avoided in the presence of combined injured ligaments or interosseous membrane injury. Three different implants are available in Korea, including the bipolar, press fit monopolar and loose fit monopolar radial head prostheses. A primary technical goal of radial head arthroplasty is the insertion of an implant that closely replicates the native radial head. The major pitfall when using a metallic radial head prosthesis is the insertion of a longer implant, which results in overstuffing of the radiocapitellar joint. Results and Conclusion: Satisfactory clinical results can be anticipated when a radial head prosthesis is used for the correct indications and when a systemic approach is undertaken to ensure proper sizing. For the future studies, we need data regarding the long term outcomes and comparison of the various types of prostheses.
