Urban disasters such as earthquake or explosion cause fire and collapses, and the residents of the affected region happen to evacuate. The factors that influence the effectiveness of evacuation include the population as well as the street conditions and the surrounding physical environments of the region. While the size of the population, either residing or commuting, is basically determined by the region's land-uses, the street condition is dependent on its width, traffic volume, and the fixed or movable obstacles installed. The surrounding environments are a comprehensive consequence of the land-use planning and the general development patterns that dominate the uses, materials, structures, sizes, and densities of the buildings. Above three are in essence the primary factors that determine the effectiveness of evacuation in case of urban disasters. This study suggests the methods to evaluate the riskiness of evacuation in terms of these three factors. The riskiness thus measured could provide fundamental data to determine the priority of investments on urban facilities and to formulate the planning guidelines for rearrangement and maintenance of such facilities.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

Seven finite element models were constructed in mandible having single screw-type implant fixture connected to the second premolar-shaped superstructure, in order to evaluate how the length, diameter and platform shape of a screw-type fixture influence the stress in the supporting tissue around fixtures. The superstructure were made using UCLA abutment, and connected to the fixture with abutment screw. Each finite element model was varied in terms of length, diameter, and platform shape of the fixture according to the commercial fixture(3i Implant Innovations Inc, Palm Beach Gardens, FL33410, USA) while the superstructure and the mandible with a single fixture placed in it shared no difference in terms of appearance. In each model, 250N of vertical load was placed on the central pit of an occlusal plane and 250N of oblique load placed on the buccal cusp. The stress distribution in the supporting tissue and the other components was analysed using 2-dimensional Finite element analysis and the maximum stress in each reference area was compared. 1. Under lateral loading, the stress was larger in the larger in the abutment/fixture interface, and in the crestal bone, compared to the stress pattern under vertical loading. 2. The amount of stress at the superstructure was similar regardless of the length, diameter and platform shape of a fixture. 3. Around the longer fixture, the stress was decreased at the bone crest and subjacent cancellous bone and increased in the cancellous bone area apical to the fixture. 4. Around the wider fixture, the stress was decreased at the abutment/fixture interface, and the bone crest and increased in the cancellous bone area apical to the fixture. 5. Around the fixture having wider platform, less stress was resulted at the abutnent/fixture interface and the upper part of the cortical bone, compared to the fixture having standard platform. In short, the stress distribution of the supporting tissue was affected by length, diameter, and platform shape of a fixture, and the fixture which was larger in diameter and length could reduce the stress in the supporting tissues at the bone-fixture interface and bone crest area.

육상으로부터 목포해역으로 영양염류가 유입되는 곳과 간조시 갯벌을 통과한 지역의 pH, DO, COD, HN_4-N, NO_3-N 및 T-P 함량을 측정하고 RMA 모형과 FIT모형을 사용하여 방조제 건설에 따른 유기물질의 확산양태를 모의하였다. 목포 인근해역의 수질은 양호하였으며 특히, 갯벌 통과 후 질소원은 증가하였고 COD와 T-P는 감소하였다. 영암/금호 방조제 건설에 따라 방조제 인근해역에서 해수이동양상이 급격히 둔화되었고 목포해역의 북쪽과 4단계 방조제 해역간의 해수교환이 크게 증가하였으며 목포해역의 남쪽에서는 외해수와의 해수교환이 크게 감소하였다. 결과적으로 방조제 건설로 인해 방조제 인접해역에 축적되는 유기물질이 크게 증가하여 목포해역 내외부의 유기물질 확산양상에 적지 않은 영향을 미치고 있다. The pH, Do, COD, NH_4-N, NO_3-N and T-P of sea water were measured in both sites effluencing sewage and passing through salt marsh, and also the RMA and FIT model were applied to the Mokpo coastal zone to analyze the changes of pollutant dispersion mechanism by constructions of the seawalls. The nitrogen source of sea water in the sites passing through salt marsh increased but COD and T-P decreased. After constructions of the Youngam/Kumho seawalls, tidal velocity was decreased and exchange of sea water was very increased between the north of the Mokpo coastal zone and the 4th seawall region and was very decreased between the south of the Mokpo coastal zone and outer sea water. The results of simulation on diffusion of organic matter indicate that most region of the Mokpo coastal zone will suffer deepened contamination after the constructions.

Background : The survival benefit associated with first-line chemotherapy in lung cancer has led to the need for second -line chemotherapy, for which Docetaxel (Taxotere^(?)) has proven efficacy in both settings. This study evaluated the safety and efficacy of docetaxel in patients with non-small cell lung cancer who had failed first-line platinum-based chemotherapy. Methods : Thirty one patients with non-small-cell lung cancer, who had failed first line platinum-based chemotherapy, between March 1999 and August 2003, were enrolled in this study. Patients received intravenous docetaxel, either 75 mg/㎡ or 100 mg/㎡, with routine premedication every three weeks. Results : Fourteen patients (45.2%) had a partial response. The median survival and progression- free survival times were 12.5 months (95% CI 7.3-17.6) and 3.0 months (95% CI 1.6-4.5), respectively. This study showed 2 factors gave different survival benefits; the age (< 60 years: 20.1 months vs. > 60 years: 6.6 months, p=0.0105) and the histological type (adenocarcinoma: 25.6 months vs. others: 7.9 months, p=0.0055). The predominant toxicity was neutropenia, which occurred as WHO grade 3 or 4 in 38.7 % of patients. One treatment related death was also reported. Non-hematological toxicity was minor and easily controlled. There were no significant statistical differences in the survival benefit and toxicity between the two doses. Conclusion : Docetaxel, as second-line monotherapy, was well tolerated and effective in patients with non-small-cell lung cancer who failed first line platinum -based chemotherapy.

This study was performed to investigate the effect of Chungkuk Jang added-diets on reducing cadmium toxiclt in rats (Sprague-Dalvley, ♂, 125 58±4.04g) used as experimental groups. There are six experimental groups, a normal group(Tn), a cadmium treatment group(control group Tc), four cadmium and Chungkuk Jang (0.25%, 0 50%, 1 00%, and 1 50%; T_1 T_2, T_3, and T_4) treatment groups which received different dietary feeding for 8 weeks each The results are as follows. 1 The amount of food intake at Chungkuk Jang mixed group(T_1, -T_2) was 3 5% greater than at the Tc group For the group fed Chungkuk Jang the average of weight gain was 4.42g/day, which showed higher value(2.79%) than the Tc(4 30g/day) group. The food efficency rate of intake Chungkuk Jang group (5.02) was a little higher without significance than that of the Tn(4 91) and Tc(4 99) groups. 2. The amount of water intake was the highest in the Tn(32.44?/day) group and 30.14% greater than that of the Tc(21.66?/day) group. For the water intake (T_3) among Chungkuk Jang added-diet groups showed the highest value(22.78?/day) relatively Cadmium intake of each group was in the range of 1.94 to 2.27 ppm and the T_3 group showed the highest cadmium intake. For the growth rate the Tc group was 7.62% lower than Tn group but the Chungkuk jang fed group resulted in a reduced fashion-about 3% in the growth process against the Tn group 3 There was no significant weight gain or loss of the organ and bone of rats among the experimental groups but in the case of liver and kidney the T_3 (8.59%. 12 36%) was higher than the Tc group 4 Cadmium accumulation was high to low in order of liver > kidney > spleen > heart > lung > testicle > brain > femoral muscle > femur >(T_1, T_2, T_3, and T_4). tibia > blood. The 70% accumulation rate was showed in liver (33 2%), kidney (31.25) and spleen (6 1%). The contents of cadmium in tissue and body-hair in the Chungkuk Jang intake groups(T_1, T_2, T_3, and T_4) were lower than in the Tc group. The chungkuk Jang added-diet groups (T_3, and T_4) showed low levels of cadmium accumulation

주기교대눈떨림와 주기교대주시편위는 이상안구 운동에서도 흔히 관찰되지 않는다. 이런 안구운동은 뇌교와 소뇌에 병변이 있을 때 나타난다고 보고되고 있다. 50세 남자 환자가 과음을 하고 난 이후 심하게 구토를 하여 입원하였다. 다음날 아침에 의식이 없었으며 주기교대눈떨림과 주기교대주시편위가 관찰되었다. 뇌자기공명영상에서는 뇌교나 소뇌에 병변없는 교뇌외수초용해증에 합당한 소견을 보였다. 저자는 아마도 교뇌외수초용해증이 소뇌와 전정신경핵의 경로중에 GABA 시스템에 이상이 발생하여 주기교대눈떨림과 주기교대 주시편위가 나타났을 것으로 추정한다. Background; Periodic alternating gaze deviation(PAGD) and periodic alternating nystagmus(PAN) are rare forms of abnormal eye movement. Multiple lesions in the cerebellum and brainstem have been reported with PAN and PAGD. Case Report; A 50-year-old man presented with severe vomiting after binge drinking. The next morning he. became vegetative state and showed PAGD and PAN. Brain MRI showed findings compatible with extrapontine myelinolysis(EPM) without any brainstem or cerebellar lesions. Conclusions; We postulate that the disturbed GABAnernic system in the pathway from the cerebellum to vestibular nuclei caused probably by EPM developed PAGD and PAN.
