The purpose of this study is to reveal the significance of musicals and find a way to utilize them in Korean language culture classes for foreigners. Korean language education aims to improve communication skills, and cultural education is necessary to help students understand not only the language but also the social background and context of the language. Accordingly, the author of this study has put together a lesson plan for Korean culture incorporating musicals, a topic that has been heretofore disregarded in Korean language education. Musicals are an appealing art medium for Korean language learners, as they provide striking visuals centered around distinct narrative structures and music. The musical "Swag Age: Shout out Joseon!," which this study focuses on, provides particularly suitable content, as it deals with social issues that are relevant even in contemporary Korean society and includes sijo (poetry), which can be used to teach traditional Korean literature. Based on the above characteristics, the author of this study outlines a Korean culture lesson plan teaching sijo through the musical "Swag Age: Shout out Joseon!" The class will be for learners of intermediate level and above, and consists of 4 sessions: 1) Understanding the overall plot of the musical, 2) Learning about Korean sijo, 3) Writing sijo based on your own life, and 4) Presenting your own sijo. This culture class is significant in that it goes beyond simply learning about sijo and enables students to internalize the meaning of and actively enjoy sijo by writing their own versions. In addition, it is expected to be a compelling class that, on top of its educational value, introduces and allows students to experience a wider range of Korean popular culture by adding the musical genre to the common repertoire of movies, dramas, plays, and pop songs often covered in Korean culture classes.

Pseudomonas sp. NGK1, isolated by naphthalene enrichment culture technique, is capable of degrading anthracene as a sole source of carbon and energy. The organism degraded anthracene through the intermediate formation of 1,2-dihydroxyanthracene, 2-hydroxy-3-naphthoic acid, salicylate, and catechol. The intermediates were isolated and characterized by TLC, spectrophotometry, and HPLC analysis. The cell free extract of anthracene-grown cells showed activities of anthracene dioxygenase, 2-hydroxy-3-naphthylaldehyde dehydrogenae, 2-hydroxy-3-naphthoate hydroxylase, salicylate hydroxylase and catechol 2,3-dioxygenase. The formed catechol as a metabolite is degraded through meta-cleavage with the formation of ${\alpha}$-hydroxymuconic semi-aldehyde.

A Pseudomonas sp. strain DJ-12 isolated by 4-cholrobiphenyl enrichment culture technique is capable of utilizing 4-hydroxybenzoic acid as a sole source of carbon and energy. The bacterium catabolized 4-hydroxybenzoic acid through the intermediate formation of protocatechuic acid, which was further metabolized. The cell free extracts of pseudomonas sp. DJ-12, grown on 4-hydroxybenzoic acid showed higher activities of 4-hydroxyenzoate 3-hydroxylase and protocatechuate 4,5-dioxygenase, but the activity of catechnol 2,3-dioxygenase was lower. The results suggest that 4-hydroxybenzoic acid is catabolized via protocatechuic acid rather than catechol or gentisic acid in this bacterium and that the protocatechuic acid formed was metabolized through a metacleavage pathway by protocatechuate 4,5-dioxygenase.

Lipase of Staphylococcus sp. was purified from the culture supernatant, and its molecular mass estimated to be 44 kDa by SDS-PAGE. Its optimum temperature and pH for the hydrolysis of p-nitrophenyl substrates was $28^{\circ}C$ and pH 8.5, respectively The gene encoding the lipase was cloned in Escherichia coli in the $NH_2$-teminally truncated form by using the shotgun method, and sequenced. The mature enzyme had a 49-93% amino acid sequence homology with other staphylococcal lipases. This lipase was used for the hydrolysis of the 3-O-acetate of cephalosporin-C to give an intermediate, deacetylated cephalosporin-C that is useful for further chemical elaborations.

We have done the input-output analysis to see the over all impact of flounder industry of Jeju region on the domestic economy of Korea. To do the input-output analysis, we have constructed the data set for the input-output table by using the existing data set in the "2003 input- output table of Jeju regional area" published by the joint work of Jeju branch of Korea bank and the Jeju Development Institute, together with some raw data provided by Jejudo Marine Fish-Culture Cooperative. We have also produced input coefficient of flounder industry by making flounder industrial sector exogenous, separated from intermediate demand. To summarize our empirical results, the inducement effect of production, value added, and employment of Jeju flounder aquaculture industry are 300 billion won, 116 billion won and 1,800 people respectively. In conclusion, the results of this study suggest flounder industry of Jeju region contributes powerfully to not only Jeju economy but also all over the Korea economy.

Mesophyll protoplasts derived from young leaves of Nicotiana rustica and N. tabacum cv Burley 21 were fused with the aid of polyethylene glycol(PEG). Cytological examination of protoplasts after PEG treatment revealed 12.8 % heterokaryocytes. After 7 weeks culture, the hybrid calli showing greenish white with a compact appearance were selected in contrast to parental type calli tinged with white or green color. The somatic hybrid plants were verified by morphological, biochemical and cyclological analysis. A heterosis effect for plant vigor and height was observed but the shape of leaves and flower characteristics were intermediate between N. tabacum and N. rutstica. The isozyme banding patterns for peroxidase of somatic hybrid lines were compared with the parent species. A number of isozyme bands derived from both parental species were found in the hybrids. Somatic hybrid plants have been successfully backcrossed to the parental N. tabacum particularly with somatic hybrid plants as female parents. These hybrid plants yielded small seeds, only few which were germinable.

Aromatic hydrocarbon degrading bacteria were isolated from industrial waste by using an agar plate method. The isolate DY-1 was identified as Acinetobacter sp. and found to utilize phenanthrene as tis sole carbon source. THe bacteria were proved to produce salicylic acid as an intermediate from phenanthrene through naphthalene pathway, when the products in the culture were wxamined by thin-layer chromatography. THe $Phn^+$ genes were found to be involved in two plasmids of about 4 and 40kb which were lost and not detected in the DNA samples prepared from the mitomycin C-cured cells by a gel electrophoretic analysis.

The purpose of this study was to examine the relationship between the safety awareness and safety practice behavior of adult learners who participated in "civic safety culture college" was held in Changwon city. We carried out a questionnaire survey that was targeted at 150 citizens, but 132 citizens were included finally. Data collected were analyzed with SPSS 21.0 statistical program. Analysis methods were t-test, one way ANOVA, Scheffe test, Pearsons correlation coefficient, and multiple linear regression. The results were as follows. First, safety awareness point was an average of 4.17 point which was higher levels. Area showing the highest safety awareness was fire safety. Safety practice behavior point was an over intermediate level of an average of 3.58 point. Second, safety practice behavior had statistically significant difference according to sex(t=2.58, p=.01), education(t=-2.57, p=.01), job(t=-1.96, p=.05), housing(t=3.65, p<.001). Third, there was a positive correlation between home safety awareness(r=.28, p<.001), traffic safety awareness(r=.37, p<.001), fire safety awareness(r=.37, p<.001), emergency care awareness(r=.45, p<.001) and safety practice behavior. Fourth, safety practice behavior was related to the emergency care awareness(${\beta}$=.34, p=.002), this factor accounted for 19.5% of the variability of the safety practice behavior. These results are expected to be very important baseline data for many different businesses and program development for strengthening of safety awareness and spreading of safety culture in Changwon city.

A structured kinetic model is proposed to describe cell growth and secondary metabolite, flavone glycosides, synthesis in batch suspension culture of Scutellaria baicalensis G. The model has been developed by representing the physiological state of cell described as the activity and viability which can be estimated based on the culture fluorescence. In the model, three type of cells are considered; active-viable, nonactive-viable and dead cells. Viable cell weight could be determined based on the relative fluorescence intensity. The flavone glycosides could be produced by both active-viable and non-active viable cells with a different production rate. And the model includes the cell expansion due to glucose concentration and death phase which accounts for the release of intracellular secondary metabolite into medium. Dependent variables include substrate concentration(glucose), cell mass(dry cell weight and fresh cell weight), product concentration(flavone glycosides), activity and viability. Satisfactory agreement between the model and experimental data is obtained from shake flask culture of Scutellaria baicalensis G. The proposed model can predict the cell growth and flavone glycosides synthesis as well as intermediate materials.

This research is to reveal an aspect of costume culture interchange in the relationship of the early Chosun Dynasty, by considering the imported goods from Japan, of the trading goods derived by the trade diplomacy between the two countries in the early Korea-Japan relationship in the medieval era. The research results are as follows. A good-neighbor Policy in the early Chosun Dynasty was established by a link of a barbarian ban policy to blockade the frequent intrusion by Japanese barbarians. The exchange was the form of presenting a return present in return for a tribute to the Chosun Dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. In trading goods between Korean and Japan. the imported goods from Japan to Korea were a wide variety of items primarily such as dyes, mordant, medicines, steel, spicers, etc. In particular, Somok used as a red mordant, which were intermediate goods to Southeast Asia, was the most heavily-traded items of imported goods from Japan. It had been consumed primarily as a raw material making the costume suit of the royal family and the aristocracy. The increased import of Somok was derived from a thought of preferred red color by our people. As its inflow was increased. the costumes tended to be luxurious In early Chosun Dynasty and resulted in social issues. This active trading from the early Chosun Dynasty caused from the communication of the Japanese envoy. In addition the study of the trading provided an opportunity that can glance at an aspect of the costume culture, though It was fractionary.
