Automobile exhaust system has difficulty in concentrating contrary technology, which has diminishing effect of maximum exhaust noises and mininum exhaust pressure for output efficiency improvement into on system. This thesis has the purpose in management of basis study for silence and output efficiency improvement which can be satisfy low noises and low exhaust pressure at the same time through maximizing engine efficiency dealing with activity as the condition of engine controlling exhaust impedance actively. In this thesis, we obtained positive result by making experiment high efficiency exhaust induced shaped silencer in order to satisfy contrary matters which device the improvement of engine efficiency and low perception of exhaust noises at the same time. That is, we proved that it has more excellent in low perceiving noises of exhaust system and output improving efficiency than existing muffler by active controlling the exhaust impedance.

The growth of auto ownership which was resulted by a rapid growth of economy and population caused a terrible transportation problem. This problem will not be improved by the supply of transportation facility. These days, it is natural for every foreign country to give a priority to the public transportation. Namely, it is necessary that the policy for travellers to attract from auto to public transportation is needed. Therefore, the purpose of this study is to find a basic idea for attracting auto users to public transportation. This study is largely divided into 3 parts. First, a travel mode choice model was estimated by using which is all the sample. Second, the mode choice models were estimated with the market segmentation divided by residential and work location. Third, the policy analysis was performed by using the estimated model.

변연성 발육성 치아종 : A Case of Peripheral Developing Odontoma

윤정훈,임경수,손홍범 조선대학교 구강생물학연구소 2003 Oral Biology Research (Oral Biol Res) Vol.27 No.1

A peripheral odontoma is a relatively rare lesion and is thought to represent the soft tissue counterpart of the central or intraosseous odontoma. Although several odontogenic tumors can occur peripherally, only a few cases of peripheral odontomas involving the gingival tissues have been reported. No earlier stage of peripheral odontoma or peripheral developing odontoma has been described. Here, we report a case of a peripheral developing odontoma occurring in the gingiva of a 4-rear-old Korean boy. Microscopic sections showed several nodules of developing rudimentary tooth germ-like structures in the gingival tissue. It seems likely that this case arise from remnants of the dental lamina located in the gingiva, since the clinical and histologic presentation lends support to the peripheral origin of this tumor.

Pyridine의 수첨탈질반응에 있어서 황화수소와 물의 영향

김경림,한창훈 연세대학교 대학원 1989 延世論叢 Vol.25 No.1

The effects of hydrogen sulfide and water on the pyridine hydrodenitrogenation over Niw/γ-Al2O3 were studied at the range of the temperature between 200℃ and 450℃, at the pressure of 1MPa and 3MPa, and at the contact time of 151.52g cat. hr/mol Pyr. The nitrogen removal in hydrodenitrogenation of pyridine was increased, but piperidine concentration of the products was significantly decreased by hydrogen sulfide. Water also increased the nitrogen removal and decreased piperidine concentration, but its effect was smaller than that observed with H2S at the same pressure. In presence of both H2S and water, the nitrogen removal was essentially the same as that-observed in presence of H2S alone. As a result of piperidine hydrogenolysis, the enhancement of nitrogen removal in hy-drodenitrogenation of pyridine is caused by the increase of hydrogenolysis activity. And the enhancing effects of H2S and water on hydrogenolysis activity were reversible.

著者들은 內臧山의 昆蟲相을 調査하기 위하여 1990년 9월까지 이 地域의 昆蟲들을 採集하였다. 著者들의 文獻調査에 의하면 이 地域에 대한 傳門的인 昆蟲相은 지금까지 두번 수행된 적이 있다. 또한 이 地域은 觀光地 임으로 여러 文獻에서 採集地 記錄되고 있다. 採集된 모든 漂本들을 同定한 結果 12目 115科 831種이 確認, 同定되었다. 그 중에서 稀貴種으로 保護가 要求되는 種은 Parnassius bremeri(붉은 점모시나비)와 Melitaea phobe(암어리표범나비), Aporia crataegi(상제나비), Spindasis takanonis(쌍꼬리부전나비), Bibasis striata(큰수리팔랑나비), Chlorophorus diadema(범하늘소), Chrysochroa fulgidissima(비단벌레)이다. In order to study the insect fauna from Mt. Maejang authors collected insects from April, 1990 to September, 1990. Up to now the insect fauna of this area has been professionaly surveyed twice according to our references studies. After we examined all the specimens, 831 species of 115 families under 12 orders were identified in this region. Among them 7 species; parnassius bremeri, Melitaea phobe, Apocrina crataegi, Spindasis takanosis, Bibasis striata, Chlorophorus diadema and Chrysochroa fulgidissima are rare species to be protected.

To examine an estimate factor and grasp the relation of difference for Ype A Behavior Pattern(TABP), Perceived Stress Questionnaire. Depression and HIT-6 in the Chronic headache client. Method: Data collected by self-reported questionnaires from 38 client in S city who were selected by criteria of IHS, from the 19^(th) of October to 10^(th) of December, 2004. Result: 1) Differences between biographical data by TABP was significant by SaSang constitutions, by Stress was significantly influenced by age, and by Depression were significantly influenced health status and SaSang constitutions. 2) Correlations Coefficients among Study Variables were Stress and Depression(r=.494, p=.002) and Depression and HIT-6(r=.432, p=.010). 3) In regression analysis, HIT-6 were significantly influenced by Depression and Type A Behavior Pattern(TABP). These variables explained 38% and 34% respectively. Conclusion: The result suggest that chronic headache management with psychological aspect, as well as physical aspect should be a focus to enhance the quality of life.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.
