Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

Background : To exatnine the problems intolved in writing practice of death certificates, we cotnpated the determination of underlying cause of death for wital statistics using recorded underlying cause of death in issued death statistics. Methods : We collected 688 rnortality certificates issue in year of 2,000 from 3 university hospitals. And we also collected vital statistics from ministry of statistics. The causes of death were coded by experienced medical record wpecialists. And causes of death determined at ministry of statistics for national vita statistics were mapped to causes of death recorded at each death certificates. The rate that underlying causes of death for vital statistics were derived from underlying causes of death recorded at issued death certificaties sere analysed. Results : 64.5% of underlying cause of death for could be derived from underlying cause of death recorded at issued death certificates, 8.6% derived from intermediate cause of death, and 3.9% derived from direct cause of death. In 23% of cases, underlying cause of death could not be derived using issued death certificates. The rate that underlying cause of death for vital statistics could be derived from underlying cause of death recorded at death certificates was different between 3 university hospitals. Ane the rate was also different between death certificates and postmortem certificates. We classified the causes of death using 21 major categories. The rate was different between diseases or conditions tha caused death too. Conclusion : When we examined the correctness of death certificate writing practice using abpve methods, cortectness of writing could not be told as satisfactory. There was difference in correctness of writing between hospotals, between death certificates and postmortem certificates, and between diseases and conditions that caused death. With this results, we suggested some strategy to improve the correctness of death certificate writing practice.

With respect to the increasing importance of understanding our environmental concerns, this study was conducted to develop the questionnaire for the comprehensive and objective measurement of environmental concerns and test its reliability. The major research methods taken include the design of environmental questionnaire based on literature review and related theories, and the process of increasing the reliability of developed questionnaire through the repetition of reliability analysis. The total of 3 surveys were conducted and the total of 510 persons including diverse sample groups were questionnaired. The SAS PC+ package program was used in the reliability analysis of surveyed data. The first designed questionnaire consisted of 50 items including 25 items related to environmental pollution and 25 items related to nature conservation, reflecting various factors of environmental concerns. The result of the first reliability analysis showed that Cronbach-αfor the total was 0.75. To increase the reliability, items having low correlation with the total were eliminated, corrected, or revised. The reliability of redesigned questionnaire consisting of 46 items was significantly improved to the level of Cronbach-α0.88, the high reliability of measurement. In the second reliability analysis, 11 items were further revised and corrected to develop the questionnaire having the very high reliability. The reliability of the finalized questionnaire was further increased to the level of Cronbach-α0.92.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

Several reports have been documented that carotid atheroma presented as the mostimportant cause of cerebral infarction in Korea. Authors analysed the atheroma imaging of the carotid artery in the patients with cerebral infarction patients using duplex sonography and color flow imaging. The atheroma extents were CCA(common carotid artery)+ICA(intemal carotid artery)+ECA(external carotid artery) or BIF(bifurcation) 47.9%. CCA(common carotid artery) 24.4%, CCA(common carotid artery)+BIF(bifurcation)+ICA(lntemal carotid artery) 11.1 %. The percents of stenosis of carotid arteries were moderate 53.6%, mild 26.1 %. severe 16.3%, critical 3.1 % and occlusive 0.9%. The surface characters were smooth 53.1 %, mild irregular 41.3%, severe irregular 3.9% and ulcerated 1.7%. The atheroma texture was homogenous 90.5%, and the echogenicities of atheroma were isoecboic 40.2%, calcification 25.1 %, hypoechoic 22.3%. We concluded that duplex sonography and color flow imaging were accurate and safe non-invasive method detecting of carotid atheroma.

PURPOSE : To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. MATERIALS AND METHODS : Direct coronal CT scans of 93 consecutive patients with chronic inflammatory sinus disease were reviewed two radiologist. The direct relationship between the optic nerves and the posterior ethmoid and sphenoid sinuses was recorded, as were indentations into the sinus wall, course of the nerve through the sinus region and bone dehiscence. RESULTS : A total of 186 optic nerves were evaluated in 93 patients. The relationship of the optic nerve to the posterior paranasal sinus fell into one of four discrete categories, type 1 through type 4. In most common form, type 1 nerves, course adjacent to the sphenoid sinus without indentation of the wall(153 nerves, 82%). Type 2 nerves course adjacent sphenoid sinus, causing indentation of the sinus wall (20 nerves, 16%). Type 3 nerves course through the sphenoid sinus(3 nerves, 2%). Type 4 nerves course immediately adjacent to the sphenoid sinus and posterior ethmoid air cell(0 nerves, 0%), Boone dehiscence was present in 11% of type 1 nerves, in 57% of type 2 nerves, and in 100% of type 3 nerves. CONCLUSION : The type 1 nerves were the most common form of the relation of the optic nerve to the posterior paranasal sinus and we had no case in contact with the posterior ethmoid sinus. Anatomic configurations that predispose the optic nerve to injury include type 2 or 3 optic nerves, bone dehiscence over the nerve. These configurations are common and should be routinely sought out so that devastating complications from surgery can be avoided.

In real world, most of plants has a nonlinearity and complexity. Thus it has a trouble for control with general control theory. Up to the present, we have controlled a nonlinear plants supposing that they was linear. But because we did so, many bad matters and errors was brought out in various area. To improve this problem this study tried to control a nonlinear plants with a nonlinear characteristic of artificial intelligence in real world. Industrial crane had a role as plant in this thesis. The critical load was measured and the optimal distance between crane and load and the angle of boom was found with neural networks. So data in table was approximated and generalized by an ability of function approximation in neural networks. The optimal angle of boom for random loads and the distance between crane and loads could be found with a inverse identification of neural networks.

"The Halfness-Child" can be regarded as the Self which draw back from the World. The Halfness-Child looks like it has no power to cope with the World. But he overcomes ultimately, not by the consciousness, but by the unconsciousness. The unconsciousness is believed that it has the ability which leads the Self to the right way and the power enough to gain the Self the life against to the World. The searcher in <Dragon slayer> tale also has the power to control the world by help of the unconsciousness, which is inner value of the Self, and sometimes contrary to the consciousness. It reflects the aspects of our real life, that is to say. We flinch from the world because we are weak, but at the same time we also have endless affirmative expectation about the power of the Self. We gain the power of the Self from inside, so it is radical and fundamental. And we have the will to realize the Self eventually, not submit to this robust World. When we read folktales we regard this will as just mirth or interest, but man reformed the world by the power of this will in the real world. The folktales like this seem like to be based on the belief that performers have in their Self that they will win ultimately, but they often don't know they have or realize.

「陶山雜詠」과「陶山十二曲」에서의 '興'

신연우 국어국문학회 2003 국어국문학 Vol.- No.133

LeeHwang's <Tosan Jabyeong> , <Tosan 12 Songs> and his thought have the concern with Nature, Saint and Human selfhood In his philosophy LeeHwang has ultra principle centric idea so he defends four right emotion and rejects seven bad inclined feelings. On the contrary in the poems he expressed delight or rejoice many times which are parts of 7 feelings. This leads us to look LeeHwang's literature and thought rather differently. Researchers were used to untie them together as one. But his literature has its own character differentiated from his thought. Through <The Prescript to Tosan Jahyeong> and <The postscript to Tosan 12 Songs>. we can understand the Delight orderly LeeHwang has dealt with. It is the feeling which bear inner order by the uniformity with Nature and LeeHwang put the element of goodness into that feeling so as to he prevent human being from overflowing of the feeling, which could lead us to vicious desire. The poems in <Tosan Jabyeong> represent the Delight to make the uniformity of Nature and Saints, especially five-word-poems show it rather concretely. LeeHwang adds <Tosan 12 Songs> with the obligation proposition through the restoration of Saint's inner rule conrolled by Heavenly Principle. LeeHwang's Delight is different fae from the ideas of poets and philosophers of Late Chosun. One of them may he Hong Dae Yong. He told Delight differently in his <The preface to Daedong Pungyo>. So after comparative research of the two, we can settle the province of LeeHwang's Delight. I'll examine it other occasion.

The flora of vascular plants and the forest structure in Mt. Chombong were studied from 1987 to 1990. 106 families, 413 genera, 801 species, 36 varieties, 17 formaties of vascular plants were classified. Of these, 35 taxa including Megaleranthis saniculifolia and Hanabusaya asiatica are endemics. Phytosociological studies indicated that the vegetation were divided into Quercus mongolica association two subassociation, Abies holophylla and Acer mono. Along the altitude gradient, the importance value of Q. mongolica was the highest at all the stand except for Betula davurica and Acer mono at 800m. Frequency distribution of DBH showed convex form in Q. mongolica but L form in Acer pseudo-sisboldianum. This means there are no natural regeneration fo Q. mongolica, recently.
