Characters in the novel are created through the combination of the novelists's creativity and his milieu he lives in. Therefore they are the novelist's other self and the projections of his society as well. From this viewpoint the writer of this thesis attempted to bring to light the works of Choi Myung-Ik against the past social background of Korea under the Japanese rule. The conclusions derived are as follows: 1. The background and the atmosphere of Choi's novels coincide with the dark, gloomy and melancholic air of the colonial days. These elements no doubt affected the characterization in his novel. 2. The discrepancy between the intellectual level of the characters in the novel and their standard of living is enormous. This hisharmony persisting in their high intellectual pursuit ('high though') and their privation ('low living') bring about the characters' neurotic symptoms of anxiety, melancholy, helplessness and alienation. This may be said to have reflected the general atmosphere of the intelligentsia of those depressed age. 3. The consistent use of the Chinese character '-'(meaning 'first, foremost, supreme' etc.) in the first names of the characters seems to suggest the elitist sense of the intelligentsia in spite of their 'low living'. This also reflects one of the distinctive qualities the 'self-conscious' characters possess, which, accordingly, must be interpreted as one of the important aspects of the intelligentsia of those days. 4. The subjective viewpoint (that is, the omnipotent viewpoint of the writer and the first person viewpoint) is employed throughout to describe the inner world of the 'self-conscious' characters. 5. The common features of the protagonists can be said to be the neurotic symptoms which come from the complex factors, such as the environment, the intellectual level, the standard of living and the viewpoint of the characters. The most not able of these symptoms are anxiety neurosis and depressive newrosis.

1986年 2月부터 同年 5月까지 大邱近郊의 都市 및 農村國民學校 學童과 孤兒院生의 蟯蟲 感染率을 Graham氏 scotch-tape檢査法으로 1回 檢査한 다음 Choi等(1973)의 調査 成績과 比較하였다. 이번 調査(1986)에서 被檢兒動 936名 中 蟯蟲卵의 檢出率은 27.8%였고 男兒 26.0%, 女兒 29.6%로서 性別間에 有意的 差를 認定할 수 없었으며 年齡이 增加할수록 높았다. 都市兒童에서의 蟯蟲卵의 檢出率은 1973年 43.4%였던 것이 이번(1986)에는 5.4%로서 顯著하게 減少되었다. 그러나 農村學動과 孤兒院生에서는 그 率에 有意的 減少를 나타내었으나 顯著하지 않았다. From February to May, 1986, urban and rural school children and institution children were examined for the presence of Enterobius vermicularis eggs in the Taegu area. All children were examined once by a modification of the Graham's scotch-tape swab technique, and compared with the results reported by Choi et al. (1973). The detection rate in 936 children was found to be 27.8 per cent. The rate in boys was 26.0 per cent, and the rate in girls 29.6 per cent. There was no significant difference in the rate with regard to sex. But the rate among the urban school children in the present study(1986) was only 5.4 per cent, and markedly decreased as compared with the rate, 43.4 per cent reported by Choi et al. (1973). However, difference in the rate of infestation in both rural school children and institution children was not pronounced between 1973 and 1986.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

The purpose of this study was to research grading work to the targets of women's wear manufacturers in Korea. For the questionnaire, 91 women's wear brands, which were in higher ranking of sales, were selected, and the age groups were separated into 3: 29's 30's, and 40's & 50's, according to their customers. The graders of each brand were questioned about 20 items for this research. The results of the questionnaire were as follows: 1. The brands for older women manufactured more sizes and cared more about somatotypes for grading than other brands did. 2. For upper garments on the basis of bust girth, the numbers of dimensional increments were different depending on the age groups: 9 for 20's, 7 for 30's, and 7 for 40's & 50's. 3. For lower garments on the basis of hip girth, the number of dimensional increments were different depending on the age group: 9 for 20's, 6 for 30's, and 5 for 40's & 50's. 4. As a model size of grading, many brands used the smallest size, but the brands for 40's & 50's also used the second size. 5. the parts needed to be corrected after grading were sleeve ease, armhole, shoulder line, neckline, crotch curve, etc. The grading with CAD system had more correction after grading than hand grading.

Using Observer, on the sensorless vector control system is a novel techniques for modern induction motor control. In this paper, a speed estimation algorithm of an induction motor using an extended kalman filter was proposed. Extended kalman filter can solve the problem, that have steady state error of estimated speed in flux and slip estimation method. The extended Kalman filter is employed to identify the speed of an induction motor and rotor flux based on the measured quantities such as stator current and DC link voltage. In order to confirming above proposal, computer simulation carried out control drives for using Matlab Simulink and show the effectiveness of the control drives for induction motor speed estimation.

The noise of the most industrial universal motor are mainly caused by the electromagnetic effect. This kind of noise can be amplified by the structure itself, if the frequency components of the magnetomotive force are close to the resonance frequencies of the structure. Therefore, there must be an intermediate process which usually called structure dynamic modification to avoid this phenomenon. In order to yield the input forces for the motor, analytical forms of magnetomotive force were obtained and those were feed to do response analysis. Through these analysis, some design guide were suggested to reduce the vibration of the universal motor.
