This study explores how folktales' motifs are used in diverse cultural contents such as literature, movies, or comics. More precisely, it is concerned with mysterious characters like Babayaga and Koshchei who appear in Russian fairytales. When the motifs of the reviewed literature are analyzed, the following three criteria are used for classification: New Writing, Rewriting, and New Version. Or course, it is New Writing that is far from the original work. Most of the collected works, including Joan Aiken's The Kingdom Under the Sea, Patricia Polacco's Babushka's Doll, Babushka Baba Yaga, and Tai?-Marc Le Thanh's BABAYAGA, belong to New Writing. The New Writing type mainly focuses on Babayaga's secluded life. In fairytales, Babayaga is depicted as the goddess of Mother Earth, the heroine of the Nature, or the ruler of the Animal Kingdom. That is why she lives in the deep and uninhabited wood. She is related to the Coming of Age ceremony. Her 'Hut on hen's legs' is an obstacle for immature protagonists to face before they come of age. Protagonists are supposed to solve the problems posed by Babayaga. If they succeed, they can get her magical help so as to complete their final mission. Babayaga is likely to appear as their antagonist. Protagonist may be subjected to a terrible ordeal created by Babayaga, and then come of age by recovering from that ordeal. Sometimes, Babayaga helps protagonists to get a grip on reality. That is why she lives in a hut in the deep and dark forest which is on the borderline between life and death. On the other hand, Marianna Mayer's Baba Yaga and Vasilisa the Brave has been classified as a controversial work between New Writing and Rewriting. It is apparently closer to New Version. However, it cannot be classified as a work of New Version because the author incorporates 'probability' into her work. Among the reviewed works, it is Korean Writer Rye, Kami's The Spider Woman's House that best reflects the essence of Babayaga. Babayaga and other characters are amusing in movies because most of the movies are animations for children. In one sense, it is positive that the scary characters in folktales are approachable to children. In other sense, however, it is regrettable that symbolic motifs are completely eliminated. In Mike Mignola's Hellboy, Japanese animations such as Index or Narutaru, on-line games such as Cabal or Vampire: The masquerade, the essence of the supernatural characters in folktales is completely eliminated, and only their 'belligerent power' stands out. It is desirable to put stories into perspective whether they are written or told. The literature property of folktales provides a special opportunity to readers. In this light, a variety of motifs have a good reason to be reborn as modern cultural contents. The bottom line is to maintain its true nature.

This study was carried out to investigate the factors affecting maturation in vitro of follicular oocytes in Korean Native Cattle. The bovine ovaries were obtained at a slaughter house and the follicular oocytes were recovered by aspirating the follicular fluid from the visible follicles of 3~6mm. The bovine oocytes were matured in vitro in TCM-199 containing FCS and hormones. The effects of TCM-199 salt type, number of oocytes per drop, incubation time and co-culture with granulosa cells on maturation of oocytes, were investigated. The results obtained are summarized as follows. 1. The maturation rates of follicular oocytes cultured for 22, 25 and 28 hours in Hank's TCM-199 or Earle's TCM-199 were 59.3, 59.6, 80% and 80.0, 90.0, 93.7%, respectively. The maturation rate of follicular oocytes in Earle's TCM-199 was faster and higher than in Hank's TCM-199(P<0.05). 2. The maturation rates of oocytes were 54.5, 62.5 and 62.0% when cultured the oocytes number 10, 20 and 40 per 200${mu}ell$ drop for 18 hours. 3. The maturation of follicular oocytes in the Korean Native Cattle was induced at 14 hours culture, by giving the maturation rate of 90.0% after 20 hours. 4. The maturation rates were 63.3% and 66.7%, respectigely when the oocytes were co-cultured with granulosa cells from medium-size follicles used immediately after recovery in the presence or absence of hormones added(0.02AU/ml FSH, 10$\mu\textrm{g}$/ml LH and 1$\mu\textrm{g}$/ml estradiol 17-$\beta$). When the oocytes were co-cultured with granulosa cells from medium-size follicles cultured for 3 days, the maturation rates were 20.8% and 76.2%, respectively(P<0.05). 5. The maturation rate were 88.0% and 70.0%, respectively when the oocytes were co-cultured with granulosa cells from large-size follicles used immediately after recovery in the presence or absence of hormones added(0.02AU/ml FSH, 10$\mu\textrm{g}$/ml LH and 1$\mu\textrm{g}$/ml estradiol 17-$\beta$)(P<0.05). When the hormones added(0.02AU/ml FSH, 10$\mu\textrm{g}$/ml LH and 1$\mu\textrm{g}$/ml estradiol 17-$\beta$)(P<0.05). When the oocytes were co-cultred with granulosa cells from large-size follicles cultured for 3 days, the maturation rates were 41.2% and 73.3%, respectively(P<0.05).

A cooling system is indispensable for the fossil and nuclear power plants which produce electricity by rotating the turbines with hot steam. A cycle of the typical cooling system includes pumping of seawater at the intake pump house, exchange of heat at the condenser, and discharge of hot water to the sea. The cooling type of the nuclear power plants in Korea recently evolves from the conventional surface intake/discharge systems to the submerged intake/discharge systems that minimize effectively an intake temperature rise of the existing plants and that are beneficial to the marine environment by reducing the high temperature region with an intensive dilution due to a high velocity jet and density differential at the mixing zone. It is highly anticipated that the future nuclear power plants in Korea will accommodate the submerged cooling system in credit of supplying the lower temperature water in the summer season. This study investigates the approach flow patterns at the velocity caps and discharge flow patterns from diffusers using the 3-D computational fluid dynamics code of $FLOW-3D^{(R)}$. The approach flow test has been conducted at the velocity caps with and without a cap. The discharge flow from the diffuser was simulated for the single-port diffuser and multi-ports diffuser. The flow characteristics to the velocity cap with a cap demonstrate that fish entrainment can significantly be minimized on account of the low vertical flow component around the cap. The flow pattern around the diffuser is well agreed with the schematic diagram by Jirka and Harleman.

Barley varieties collected from 1940 to 1951 allover the Korean peninsula by Dr. Takahashi Ryuhei were reintroduced from the Research Institute for Bioresouces in Okayama University, Japan, and the evaluation of morphological characteristics and RAPD analysis were performed. Totally, 493 varieties of Korean barley landraces were planted in the green house, from which seeds of 491 varieties were harvested and conserved in the seedbank of the Rural Development Administration. Majority of the naked barley varieties showed dense spikes with long awn, late heading, winter habits, and long plant height. However, variants having various phenotypes such as short awn, blue aleurone color, brachytic type and waxyness were also identified. Plant height, spike length, and cold-tolerance in the varieties were also highly variable among them. Homogeneity tests on the variation of growth habits, spike density, anthocyanin pigmentation on the seed coat, and hairiness on leaf sheath between naked and covered barley showed that the variations of naked barley were similar to those of covered barley. It maybe indicate that the most of naked barley landraces were mutated from the covered barley landraces. Korean landraces of naked barley were broadly divided into 4 groups by the dendrogram produced by morphological characteristics; however, the identities of the group were rather indistinct. Many varieties, belonged to the same group, were showed different band patterns in RAPD analysis using 5 different primer sets. These results indicate that the 112 varieties of naked barley landraces were different genotypes.

The purpose of this study was to evaluate the general features of allergic patients in northwestern Chungcheongnamdo who visited Soonchunhyang University Cheonan Hospital. The subjects in this study were 1692 suspected allergic patients. After their allergic symptoms were checked and a MAST-CLA test was conducted, the following results were obtained: 1. The mean age of the subjects was 23.1 years old. The male patients represented 56.2% and the female patients accounted for 43.8%. 1387 (82.0%) patients of those investigated suffered from allergic disease. 2. Among the 1387 patients, 1022 (73.7%) patients showed an increased total IgE level. The positive rate of those who were in their 40s (87.0%) was the highest, but their age made no difference to their positive rate of total IgE. 3. Concerning the positive rate for allergen specific antibody by age, those who were in their teens (73.5%) topped the list and similar in all age group except in their 40s. By gender, the positive rate of the male and female were 56.3% and 43.9% respectively. Regarding the positive rates by allergic disease, those who suffered from allergic rhinitis (60.4%) were most vulnerable, followed by the patients with allergic dermatitis (47.4%), with bronchial asthma (47.2%) and with urticaria (39.4%). 4. As for seasonal positive rates, they were most susceptible in April (77.2%) and May (71.1%). We discovered a significant difference according to seasons; Spring (60.1%), Winter (45.4%) and Summer (39.2%). 5. In case of Korean inhalent panel, the most dominant allergen-specific antibodies were "Cockroach mix" (31.1%), followed by "D. pteronyssius" (23.8%) and "Dog" (14.3%). In the event of food panel, the most popular allergen-specific antibodies were "D. farinae" (25.0%), followed by "D. pteronyssinus" (19.8%) and "Hose dust" (12.0%). 6. The residential type made no difference to the positive rates of "House dust", "Cockroach mix" and "Dog" as major antigen but compared with others, positive rates for "Tick" were somewhat higher in apartment buildings.

CFC-12 used in mobile air conditioning(MAC) system has been replaced by R-134a, a type of HFC refrigerant, from 1991 to 1994. R-134a has since been widely used as a refrigerant of a mobile air conditioner. However, it is one of the six main green house gases listed in Kyoto Protocol, which makes it imperative to regulate its emission and develop alternative refrigerants. In this study, the concentration of leaked R-134a was measured using VT(Variable Temperature) shed and Running loss test shed to analyze the level of air conditioner refrigerant leaked in a vehicle. According to the analysis of the concentration of R-134a leaked from a vehicle parked, annual leakage amount of R-134a was in the range of 6.46~13.28 g/yr. The figure was similar with the leakage from the mobile air conditioning system currently used. In a study using the same vehicle model, a vehicle equipped with dual evaporation system had a higher leakage rate of refrigerant than a vehicle with a single evaporation system. It appears that the added fittings and joints of the dual evaporator system led to higher leakage rate. Besides, the analysis of the change in R-134a concentration under various car speed found that more refrigerant leaked under high speed(100km/hr) and but the volume of the wind did not affect to the variation of refrigerant leakage.

The purpose of this study was to analyze the effects for lifestyle, stress and life satisfaction on sleep quality in university students. The participants were 46 university students attending the department of occupational therapy. Participants responded to responses to the lifestyle questionnaire and Morning and Evening Questionnaire-Korean version(MEQ-K). The levels of stress and life satisfaction reported by participants were obtained using the Korean version of Perceive Stress Test-4(K-PSS-4) and Korean version of Satisfaction With Life Scale(K-SWLS). The quality of sleep was assessed using Korean Modified Leeds Evaluation Questionnaire(KMLSEQ). An independent t-test, Pearson correlation analysis, and multiple regression analysis were performed to investigate factors related to quality of sleep. The analysis of correlations between health status, morning type of chronotype, and life satisfaction showed a significant positive correlation between quality of sleep. As a result of analyzing the quality of sleep according to the chronotype, the main family house and dormitory group showed higher sleep quality than the boarding group. As a result of the multiple regression analysis, the chronotype predicts quality of sleep. This study could provide information to improve the quality of sleep for university students by identify factors affecting sleep for university students in occupational therapy.

Through an experiment with gas chromatography carried out using diethylene glycol succinate(DEGS) as the packing material of the column, we have obtained the correction factor between the weight ratio and the peak dimension of the saturated fatty acid methyl esters of C10, C12, C14, C16, and C18 and unsaturated fatty acid methyl esters of oleic acid, linoloic acid, and linolenic acid, employing the detector of thermal conductivity type. Quantitative analysis of the fatty acids contained in rice Bran oil was performed with the above correction factor and the results are as follows; 1. Main components were found to be palmitic acid, oleic acid sand linolenic acid. No trases of capric acid (C10) lauric acid (C10) were found. 2. It was confirmed that there were straight line relation between the logarism retention time of each fatty acid and the number of carbon of saturated fatty acid or the number of double bond of other fatty acids having the same number of carbon. 3. The correction factor became larger as to the number of carbon increased up to C18 in case of saturated fatty acids, end as for other fatty acids, and as for other fatty acids of the same carbon number, it became larger according as the number of double bond increased.

The residue distribution ratio of pesticides among the flesh, stem and leaves of hot peppers were investigated to assure the safety of pepper powder and pepper leaves. Mixed solutions of chlorothalonil (wettable powder), kresoximmethyl (water dispersible granules) and procymidone (wettable powder) were applied once onto pepper plants in a plastic film house. After 7 days, the fruits and leaves were harvested and the fruits were divided into the flesh and stems. Pesticide residues in each pepper part were then analyzed by gas chromatography. The results showed that the concentration ratios of the chemicals in the flesh:stem and flesh:leaf ranged from 1:2-5 and 1:11-39, respectively, depending on the chemical evaluated. The observed flesh:stem ratio indicates that the pesticide content of the pepper powder product can increase by 20% if pepper stems are included in the powder product. The Korea Food and Drug Administration does not set a pesticide maximum residue level (MRL) for pepper leaves if a residue ratio in leaves over flesh is more than ten times. Results from this study support non-MRL status on the pepper leaves for the studied pesticides. Additionally, we recommend that the chlorothalonil product of a wettable powder type include the phrase "prohibition of distribution or sale for pepper leaves as food" because chlorothalonil highly resided in pepper leaves as more than twenty-four times that is a criterion level to determine an inclusion of the phrase in the label of pesticide product.
