The family of Hyun Chin-gun, whose ancestors were, for gener- ations, engaged in the expert officials as translators, belonged to the middleclass during the Yi dynasty. And this was the result that they tried to maintain the social status of their family and make it higher under the hierachy of that time. At the enlightened age (late 19c), the members of Hyun's family learned at the foreign language school, the first modern institution of learning, and they worked at the various fields as rising elites. And so, participating actively in the epoch of rapid change, they could belong to the various political groups. Their social positions and activities had the important effects on the formation of Hyun's world-view. That is, by help of the social and political sense, Hyun was able to see through the actual world and recognize the optimistic view of it. He, however, lived the time of colonial situation that didn't allow it him to get such. Therefore, Hyun understood the actual world in the duality of affir- mation/negation, and dreamed of the new world with unity. From this point, Hyun aimed the optimistic romanticism. And it showed him the new vision, through that he could get over the colonial and dark situation. Like this, he sought after the optimistic world-view, but he did not look away the actual world in sufferings. On this, we can see the sincerity of his literature.

玄吉彦 제주대학교 1985 논문집 Vol.21 No.1

Hyun Chin-gun has consistently sought for the relationship between the society and self under the actual conditions of the colony. He makes a pilgrimage to the historical spot in order to have a new understanding of the history. Its record is well expressed in two books, The Pilgrimage to the Ancient Capital, Kyungju and The Pilgrimage to Tangun's Holy Remains. In the former he investigates the bidden racial spirit by recognizing the history newly under the reality of today along with the travel to Kyungju. He looks for the generating power which enables him to create a new world out of the declining reality. In this way he pursues the unification of art and politics. In the latter he transcends the devastated reality through the productive imaginative power about the beautiful mountains and streams and about the historical relics and remains by gaining an insight into the history since the first Korean state founded by Tangun. This power of transcedence makes a history idealized and leads to the task of the restoration of national prestiges of the national literature.

Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

The structure of Rha, Do-hyang's novels-self-consciousness vs. inner conflict and desire vs. frustration-'has a close relationship to the living-style of the people who lived through the period of disorder and upheaval in Korea. Especially, this self-consciousness has a considerable significance in that it was formed in the chaotic socail order. It is from the limping motives such as passion, immorality, and material desire that the chaotic social order. In Rha's novels the limping actions taken through self-consciousness destroy the human an relationship in the existing social order, and in the end, its impossibility of establishing a new human relationship leads to adding up choas. Therefore, such actions brings about tragic catastrophe and the soaring desires are frustrated and blocked. This is the limit of this self-consciousness, of the subjugation of inner conflict, and of realistic self-soaring; therefore, it can be said that the chaotic social disorder is shaped in the structure of his novels. The other side of such a structure of Rha's novels is based on writer's human experiences. In other words, in this structure his life is expressed through which he gave up a secure living for his literary qrdor and attemped a selp-soaring. The literary historic significance of Rha's novels Lies in the fact that in this structure of them he creatively represent the Korean social structure of 1920's, the period of upheaval and the consciousness of the people who lived in the chaotic society.

The objective of this paper is to analyze the characteristics of wave transmission through various junctions with various aangles in coupled beams. The in-plane vibration as well as the out-of-plane vibration are generated due to the wave conversion at the junctions in the coupled beams. The out-of-plane vibration is associated with Propagation of out-of-plane waves (flexural waves). The in-plane vibration is associated with propagation of in-plane waves (longitudinal and torsional waves). In order to effectively reduce vibration and structure-borne noise, it is necessary to understand the characteristics of wave conversion at various junctions in the coupled structures. The numerical results in this paper have showed the characteristics of wave transmission through various junctions in coupled beams. Those could be helpful to designer to develop the idea to reduce vibration and structure-borne noise.

Vibration of cylindrical shells are generated by elastic waves propagating on the vibrating cylindrical shells. The propagating elastic waves include out-of-plane waves and in-plane waves. The out-of-plane waves correspond to flexural waves and the in-plane waves correspond to longitudinal waves and shear waves. In order to understand vibration characteristics and sound radiation characteristics, it is required to separate contributions of the structural vibration by out-of-plane waves and in-plane waves. In this paper, the Fourier analysis and Prony method have been implemented to separate the contribution of the simulated structural vibration of by the out-of-plane waves and the in-plane waves.

The power flow analysis(PFA) can be effectively used to predict structural vibration in medium-to-high frequency ranges. In this paper, vibration experiment has been performed to observe the analytical characteristics of the power flow analysis of the vibration of a beam. In the experiment, the loss factor of the beam and the input mobility at a source point have been measured. The data for the loss factor has been used as the input data to predict the vibration of the beam with PFA. The frequency response functions have been measured over the surface of the plate. The comparison between the experimental results and the predicted results for the frequency response functions showed that PFA can be an effective tool to predict structural vibration in medium-to-high frequency ranges.
