Spring time is a favorable season to be easily observed the Yellow Sand phenomenon in East Asia. In particular most of the phenomenon tend to occur in April. However, Yellow Sand phenomenon was observed from almost the whole country of Korea in winter of 1966, 1977 and 1999. The features of the synoptic weather pattern in the source regions, air stream flow between the source region and Korea, the measurement of TSP concentration, aerosol size distribution, and chemical composition of snow samples associated with Yellow Sand phenomenon were investigated. The result showed the characteristic evolutionary feature of the synoptic system associated with Yellow Sand phenomena, that is, a strong low level wind mobilized the dust within 2 or 3 days before Yellow Sand phenomenon being observed in Seoul. The wind was remarkably intensified in the source region on January 24, 1999 under the strong pressure gradient, A trajectory analysis showed that the Yellow Sand particle could be reached to Korea within 2 days from the source region, Gobi desert, through Loess plateau and Loess deposition region. The TSP concentration at the top of Kwanak mountain during the Yellow Sand phenomenon is abruptly increasing than the monthly mean concentration. The size resolved number concentration of aerosols ranging from 0.3 to 25${\mu}{\textrm}{m}$ was analyzed during Yellow Sand episode. It was evident that aerosols were distinguished by particles in the range of 2-3 ${\mu}{\textrm}{m}$ to result in the abrupt increase in January 1999, After Yellow Sand phenomenon, there was heavy snow in Seoul. By the analysis of snow collected during that time, it was observed that both the Ca(sup)2+ concentration and pH were increased abnormally compared to those in the other winter season.

'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

Sloshing phenomenon is a complicated free surface flow problem that increases the dynamic pressure on the sidewalls and the bottom of the storage tanks. When the storage tanks are partially filled, it is essential to be able to evaluate the fluid dynamic loads on the tank's perimeter. In this paper, a numerical code was developed to determine the pressure distribution on the rectangular and trapezoidal storage tanks' perimeters due to liquid sloshing phenomenon. Assuming the fluid to be inviscid, the Laplace equation and the nonlinear free surface boundary conditions were solved using coupled boundary element - finite element method. The code performance for sloshing modeling was validated using Nakayama and Washizu's results. Finally, this code was used for partially filled rectangular and trapezoidal storage tanks and free surface displacement, pressure distribution and horizontal and vertical forces exerted on the tanks' perimeters due to liquid sloshing phenomenon were estimated and discussed.

The purpose of this study is to reveal that the deconstructive dis de phenomenon in contemporary fashion beauty design can be interpreted from the viewpoint of Korean aesthetics by having an open mind of coexistence. The typical characteristics of dis de phenomenon are decomposition, decentralization, and discontinuity, and these can be compared with beauty of non-artificialness, unity, and humor, which are characteristics of Korean aesthetics. In other words, the dis de-phenomenon rejects traditional composition and uniformized expression, and seeks various images by accepting the bi-national confrontation concept, this is similar to Korean aesthetics, which experienced atypical diversity by concentrating on the inner spirit rather than the outer form through indifference to technique, form, and honest human emotion.

TVs or computer monitors with speakers often have a phenomenon called microphonic which shows fringe-like dark pattern on their screens. The major source of this phenomenon is vibration of the shadow mask inside of the Cathode RAY Tube(CRT) which is caused by the sound generated from the speakers. Reducing phenomenon microphonic by modifying the structure of the shadow mask frame in CRT has been examined in this study. A 15" for computer monitor were chosen. Using finite element analysis for vibration and impact, shape of the shadow mask frame was found to reduce microphonic phenomeon. Improved 15" monitors showed good results.d results.

The treatment of chronic digital pain and cold intolerance due to Raynaud's phenomenon is quite difficult especially it is combined with scleroderma. Several surgical trial such as cervicothoracic sympathectomy have been attempted for the medically unresponsible Raynaud's phenomenon, but their results were unsatisfactory. We have tried peripheral periarterial sympathectomy for the 44 years old female patient who had medically unresponsible severe Raynaud's phenomenon with scleroderma. Periarterial adventitial stripping was performed at the level of wrist, superficial palmar arch, common digital artery and proper digital artery about 1.5-2 cm in length. Preoperative angiography and radioactive angiography were done and preoperatively and postoperatively the blood flow was measured by the desk top computer-aided histogram. Both hands digital pain were markedly reduced after operation and blood flow increased as compaired with the preoperative measure.

The coastal urchin barren phenomenon in our country began to spread and expand from the 1980s, centering on the southern coast and Jeju Island, and by the 1990s, it appeared along the east coast and nationwide. The urchin barren phenomenon is mainly conducted through field surveys by diving, but recently, various surveying techniques have been applied. In this study, a spectral library for terrestrial and marine areas was established for the identification of urchin barrens using airborne hyperspectral imagery, and the distribution area was analyzed through the SAM (spectral angle mapper) algorithm. An analysis of the urchin barren phenomenon in the five islands of the West Sea revealed that it occurrs in most areas, with the combined severity of the urchin barren phenomenon in Sapsido and Oeyeondo being approximately 19.9%. Hyperspectral imagery is expected to be highly useful not only for detecting the urchin barren phenomenon but also for managing and monitoring marine fishery resources through the classification of seaweeds.

In this study, New Orientalism represened in modern fashion is defined a new idea that harmonized with factors of eclecticism, traditionalism, naturalism, and futurism and these characteristics are examined. First, as these features, it is the phenomenon of eclecticism presented beyond regions and sex. Second, it is the phenomenon of traditionalism newly expressed traditional images in a modern sense by using and changing of a oriental dress image of the of the past. Third, it is the phenomenon of naturalism revealed an unalloyed recurrent instinct about nature and a desire for yearning. Fourth, it is the phenomenon of futurism which is come out the factor of oriental images whithin a minimal and cyber environment. This paper might be the foundation for Korean Orientalism which could be not a just pastiche but a cultural commodity and s main fashion current with a cultural identity especially in the year of 2000, "New Arts Year", declared by Ministry of Culture and Tourism.

The purpose of this theses is to review Hanliu phenomenon, a kind of social and cultural phenomenon, in China around A. D. 2000 in the view of the culture-diffusion theory, and analyze its effect to the fashion style of the new young generation of China. In this theses, Hanliu phenomenon means the enthusiasm of Asian people for Korean mass cultures such as Korean dramas, pop songs and fashions from late 1990's. This research adopts two kinds of methods for analyzing Hanliu phenomenon: a qualitative research method and a quantitative one. As a qualitative research method, we analyzed Hanliu phenomenon with several sources of documentaries and audio-visual materials on it. As a quantitative research method, we conducted a survey of about 100 university students in Beijing for how they feel of korean culture and fashions. The Hanliu phenomenon leads to the popularity of Korean products and the general Korean cultures. Also, it affected the Chinese young generation so much that the Korean fashion becomes popular among them. Its effects to the fashion styles of Chinese youths can be summarized in three factors as follows. Firstly, the fashions of Korean entertainers such as H.O.T hair style and Hip-hop fashion style are widely imitated. Secondly, the preference of Korean fashion products has been widely increased. The number of stores dealing with Korean fashion products has been increased. Finally, Korean culture and products have actively been imitated in China according to the increased popularity of Korean fashion products.

In this study we investigate the background of UPS output transformer(${\Delta}-Y$) operation on neutral ungrounded system, and perform field experiment of neutral floating-phenomenon for the inter-locked securing of electric facilities and improvement of neutral floating-phenomenon. Experiment results show that a floating-phenomenon occurs when four-pole input-breaker trip and the neutral to earth voltage occurring concurrently is identified as phantom voltage. And the measures for the transient overvoltage that can occur in floating-state also are investigated. As a result, the risk elements of neutral ungrounded method as well as neutral floating-phenomenon are removed by installation of separate solidly-grounded transformer and switching four-pole input-breaker to three-pole input breaker.
