Streptomyces albidoflavus C247 was isolated from the soil of the Gyeongsan golf course in Korea. Physiological, biochemical and 16S rDNA gene sequence analysis strongly suggested that the isolate belonged to Streptomyces albidoflavus. Preliminary screening revealed that the isolate was active against fungi and bacteria. Self-directing optimization was employed to determine the best combination of parameters such as carbon and nitrogen source, pH and temperature. Nutritional and culture conditions for the production of antibiotics by this organism under shake-flask conditions were also optimized. Maltose (5%) and soytone (5%) were found to be the best carbon and nitrogen sources for the production of antibiotics by S. albidoflavus C247. Additionally, 62.89% mycelial growth inhibition was achieved when the organism was cultured at $30^{\circ}C$ and pH 6.5. Ethyl acetate (EtOAc) was the best extraction solvent for the isolation of the antibiotics, and 100 ${mu}$/ml of EtOAc extract was found to inhibit 60.27% of the mycelial growth of Rhizoctonia solani AG2-2(IV) when the poison plate diffusion method was conducted.

The purpose of this study is to present as an alternative to a new policy of the regional level about actively adopting of the Sharing Culture and to suggest policy direction of Talent Sharing activities as an intermediary Sharing activities. To achieve this, We derive a significant outcomes as compared mutual to the center of a volunteer manager and volunteer groups for talent sharing activities in Busan Area. As a result, several suggestion are presented as follow : First, we needed to build for systematic control of talent sharing activities around existing volunteer management institution. Second, Supply and Demand control system is needed to build for talent sharing activities at the local government dimension. Third, To reflect the trend of the people watching the activity with some degree of talent, expertise as a talent sharing activity, Talent sharing volunteers are needed for specialized capability verification. Finally, Sharing activities are needed to settle major policy for the systematic management of talent sharing activity and to expanded budget support of local government at the local government dimension.

Bioleaching studies of metals from a spent catalyst were conducted using both adapted and unadapted bacterial cultures. The bacterium used in this experiment was Acidithiobacillus ferrooxidans. A comparison of the kinetics of leaching was made between the two cultures by varying the leaching parameters, including the pulp density, particle size and temperature. Both cultures showed similar effects with respect to the above parameters, but the leaching rates of all metals were higher with the adapted compared to the unadapted bacterial cultures. The leaching reactions were continued for 240 h in the case of the unadapted bacterial culture, but only for 40 h in the case of the adapted bacterial culture. The leaching reactions followed first order kinetics. In addition, the kinetics of leaching was concluded to be a diffusion control model; therefore, the product layers were impervious.

This study was conducted to track the appearance of Aguijjim and its popularity on the national level. Furthermore, changes in the monkfish recipe and how they impacted the consumption of monkfish were investigated. It is assumed that monkfish was consumed by Japanese in Korea during the Japanese colonial era. After liberation, people cooked the fish as soup. In the 1960s, Aguijjim was invented in Masan. There is great controversy regarding how the dish was born. It has been asserted that it was created by one specific person, that refugees with insufficient food developed, and that it is just an advancement of Bugeojjim. Aguijjim restaurants began to appear in Seoul in the 1970s, and in the 1990s streets full of Aguijjim restaurants formed. Moreover, popular music and literature referenced Aguijjim in the late 1990s. As Aguijjim has developed and the formation of Aguijjim street have combined, the consumption of monkfish has increased drastically, leading to its import. As cooking methods have transformed, the fish with the unpleasant look which was thrown out in the past, have dramatically gained public interest. 'Masan Aguijjim' became an independent brand that represents a local food that has also been nationalized in a short amount of time.

This study was performed to analyze the antibacterial activity against food hazardous microorganisms and antimutagenic effects of Sanguisorba officinalis L. ethanol extracts on Salmonella Typhimurium TA100. The antibacterial activity was evaluated by paper disc diffusion assay, minimum inhibition concentration (MIC), and optical density of the culture with the ethanol extract for 24 hr. Antibacterial activity was tested with seven microorganisms including Escherichia coli, Escherichia coli O157:H7, Pseudomonas aeruginosa, Salmonella Typhimurium, Listeria monocytogenes, Bacillus cereus, and Staphylococcus aureus. The paper disc diffusion assay showed distinct clear inhibition zones around the discs treated with the extract for five microorganisms, except Escherichia coli and Escherichia coli O157:H7. MIC values were 0.625-2.5 mg/mL for these five strains that showed clear zones. The time-kill assay was consistent with the results from the paper disc diffusion assay and MIC test. Additionally, antimutagenicity of the extract was determined using the Ames test. The ethanol extract at 5 mg/plate inhibited 72.42% and 89.85% of mutagenicity induced by 4-nitroquinoline 1-oxide and sodium azide, respectively. These results demonstrate that the ethanol extract from S. officinalis L. has remarkable antibacterial activity and antimutagenicity.

Recently, Southeast Asian people, its food, natural sceneries and so on have been increasingly exposed to Korean people through mass media and multi-cultural events. At the same time, Koreans can frequently encounter Southeast Asians in their everyday lives. Thus, specific images and discourses of Southeast Asia has been established in our society, which creates a new social trend called 'Southeast Asia phenomena'. In short, 'Southeast Asia phenomena' means a totality of Korean people's experience of Southeast Asian and their perception on the region. On the one hand, 'Southeast Asia phenomena' is a result of inflow of Southeast Asians and their culture into Korea. On the other hand, it is also a consequence of Korean people's understanding of Southeast Asia from their trip to Southeast Asia or from their interactions with Southeast Asian people. This article aims to analyze the origin and diffusion of 'Southeast Asian Phenomena' in Korea in the context of Southeast Asia focusing on 4 topics, that is, migrant workers, overseas investments, retirement migration, study-abroad categorized as human movement. This article is also about a country-by-country comparative analysis both at the macro level and the micro level. At the macro level, overseas investments and trade, human exchanges, positive perception to Koreans which considered to be the structural causes become a strong mechanism playing a important bridge role between Korea and Southeast Asia. So these create the high probability of the emergence of 'Southeast Asian Phenomena' At the micro level which is more direct causes of 'Southeast Asian Phenomena', the economic cause is the most important common cause for 4 Southeast Asian Phenomena. Additionally, Korean wave is also remarkable common cause creating 'Southeast Asian Phenomena' even it is not the origin in the context of Southeast Asia. The diffusion of 'Southeast Asian Phenomena' is different by the topics and the elements contributing to create the favorable situation for the diffusion are not only overseas investments and trade, human exchanges at the macro level but also policy elements at the micro level. The relative differences of the causes of 'Southeast Asian Phenomena' in the country-by-country analysis are found. Regarding overseas investments in Vietnam and Cambodia, the economic degree of freedom in Cambodia is higher than in Vietnam. Even Korean Wave has had the longer history in Vietnam, but the favorable perspectives on Korean Wave are stronger in Cambodia. For migrant workers from Vietnam and Indonesia, the economic causes in Vietnam are more significant than in Indonesia. The impact of Korean Wave is stronger in Vietnam than in Indonesia. In case of study-abroad, the social-cultural elements and policy elements are more diverse in Malaysia than in Korea. For the Korean retirees who immigrate to the Philippines and Malaysia, the economic causes in the Philippines is more significant in Malaysia.

Si on examine le bilan 2014 du CNC en France et celui du KOFIC en Corée du Sud, on peut s'apercevoir que l'éhelle industrielle cinématographique des deux pays est très similaire. On peut découvrir quelques chiffres à propos des résultats de l'industrie cinématographique dans ce bilan comme le nombre d'entrées, la recette des guichets, le nombre de production qui sont très similaires. La part de marché pour les films nationaux des deux pays augmente fortement en 2014. Mais ces chiffres de marché pour les films nationals sont les résultats obtenus dans les situations trés différentes des deux pays. En ce cas, la différence entre les deux pays vient d'où? Il en résulte de la politique de la culture cinématographique pour 'la sensibilisation du film comme une culture' des deux pays. Ceci est la partie la plus importante de la différence, qui est également visible dans la politique de la culture de France et de Corée du Sud. Depuis quelques années, le cinéma coréen se développe considérablement, à l'intérieur comme à l'extérieur du pays. Cependant, ce succès masque un certain déséquilibre de l'industrie cinématographique. On se rend compte également de la concentration du pouvoir par la monopolisation des grandes entreprises qui fonctionnent selon le principe de l'intégration verticale, et qui contrôlent toute la chaîne du marché cinématographique, de l'investisse111ent à la diffusion en passant par la production et la distribution. Il est impossible de trouver une solution dans des conditions défavorables où le phénomène du fort accaparement de l'industrie cinématographique coréenne est couplé avec à une logique industrielle de libéralisation du marché. Pour résoudre la monopolisation de l'industrie cinématographique coréenne, qui pose des problème décisifs et partials sur le marché, il va falloir une politique équilibrée de la promotion de la culture cinématographique menée par le KOFIC (Korean Film Council) qui est une organisation financée par le gouvemement. On voudrait proposer une politique de la culture cinématographique qui serait adaptée à la politique du cinéma de la Corée du Sud, à travers des recherches sur la situation actuelle ainsi que l'analyse comparée cles politiques du cinéma entre Corée du Sud et France.

In the 'Society of the Spectacle', Guy Debord argued that modern life was dominated by the commodity form and the false desires it engendered. He predicted in 1967 that culture would become the driving force in the development of the economy by the end of the century, He was sure when culture becomes nothing more than a commodity, it must also become the star commodity of the spectacular society. Fashion, the starriest of star commodities with its seductive fantasy approaches to the viewers occluding the commercial reality. From this point, the spectacular property of the modern fashion can be found. This study starts on the notion that the modern fashion is on the center of capitalist consumer culture and is constructed by spectacle. On this premise, the purpose of this study is analysing the attribute of 'spectacle' and 'keeping distance ￡Tom spectacle' in modern fashion expressed in fashion show, fashion media and fashion store. The fashion houses in the 1990s that recognised the commercial value of shock and spectacle were eager to employ young spectacularly visible named designers. They generated the publicity necessary for sales of perfume, cosmetics, bags and diffusion range of clothes through the visible fashion show and fashion media. In the fashion show and fashion media, fashion goods as the commodity both flaunts and disguises its commercial nature in spectacle. The spectacle on the fashion store is the process turning the commodity into image to arouse viewer's higher interest. In the fashion store, the appearance of the commodity such as space, display, package is considered more importantly than its 'utility value'. Meanwhile, the study also covered the innovative trial to evade the ubiquitous 'spectacle' in fashion area.
