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. (Tuberc Respir DiS 2005: 58: 465-472) 연구배경 : 일차항암화학요법 후에 생존의 이득을 얻었음에도 불구하고 비소세포폐암 환자들의 대다수가 결국은 재발하거나 진행성 병변을 보인다. 이에 저자들은 기존의 여러 연구에서 보고 된 구제요법으로서 docetaxel의 항암효과와 비교적 적은 독성의 결과를 바탕으로,platinum을 근거로 한 항암화학요법을 시행 밖았으나 개발되거나 진행된 비소세포폐암 환자들을 대상으로 docetaxel 단독요법의 치료효과와 부작용에 대하여 알아보고자 하였다. 방법 : 조직학적으로 비소세포폐암으로 진단을 받고 platinum을 근거로 한 항암화학요법을 받았으나 재발 또는 진행성 병변을 보인 31명의 환자들을 대상으로 docetaxel 75 mg/m² 또는 100 mg/m²을 3주마다 정주하였다. 임상기록을 통한 후향적인 방법으로 분석하였다. 결과 : 1) 재발 또는 진행성 병변을 보인 31명중 남녀 비는 24:7이고 중앙연령은 60세였다. 2) 반응평가로 완전 관해는 없었고 부분관해는 14명(45.2%), 불변이 10명(32.3%), 진행이 7명(22.6%)으로 전체적인 반응율은 45.2%이었다. 3)중앙생존기간은 12.5개월(95% 신뢰구간: 7.3개월 17.6개월) 이었고, 1년 생존율은 52%였다. 무진행생존기간의 중앙값은 3.0개월(95%신뢰구간: 1.6개월 -4.5개월)이며, 반응군에서의 중앙반응지속피간은 3.7개월(95% 신뢰구간: 3.0개월 - 4.4개월)이었다. 4) 60세 미만인 경우(20.1 months vs 6.6 months. p=0,0105), 조직학적 아형이 선암일 경우(25.6 months vs 7.9 months, 0=0.0055) 통계적으로 유의한 생존기간의 증가가 있었다. 5) 부작용으로 3도 이상의 백혈구 감소증은 12명(38.7%),호중구 감소증에 동반된 발열은 6명(19.3%),감염이 동반된 호중구 감소증은 4명(12.9%)에서 발생했다. 치료와 관련되어 1명이 사망하였다. 6) Docetaxel 용량에 따른 생존기간의 차이나 독성의 차이는 없었다. 결론 : Platinum을 근거로 하는 항암화학요법으로 치료받은 후 재발 또는 진행성 병변을 보이는 비소세포폐암환자들에게 docetaxel을 투여하는 것은 비교적 안전하고 효과적인 항암치료법으로 사료된다.

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.

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.

Most expert systems infer typically by using knowledges i.e.. rules and facts. If we grouped knowledges of the expert system effectively, it is very easy to maintain them. And we also can infer new knowledges from them efficiently because the inference is done only on a set of the finite grouped knowledges. In this paper, we propose a method in which some common attributed knowledges or some related knowledges are grouping efficiently. To show in we describe and algorithm which groups the rules of the expert system. and also we present a method which infers new knowledges by using the grouped knowledges.

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.

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.

사범대학 영어 강의에 대한 학생들의 인식 및 만족도 조사

이 연구는 교사교육의 국제화를 지향하는 사범대학 특성화 프로그램 개발을 위한 기초 조사 차원에서 2007학년도 1학기에 146명의 사범대학 학생들을 대상으로 전공 영어 강의에 대한 인식과 만족도 등에 대해 설문조사의 방법으로 이루어졌다. 학생들의 영어 능력에 대한 자기 평가 결과, 대부분의 학생들이 자신의 영어 능력이 영어 강의 수강에 부족하고, 영어 강의에 대한 심리적 부담이 크다는 반응을 나타냈다. 또 영어 강의가 한국어 강의에 비해 전공 지식을 쌓는 데 도움이 되었다는 반응은 이공계를 중심으로 한 기존의 연구 결과보다 상대적으로 낮게 나타나는데, 이는 사범대학 영어 강의의 운영과 관련하여 좀 더 다양하고도 효과적인 방안이 고려되어야 함을 시사한다. 영어 강의 수강 시 어려움을 묻는 질문에서 과제 발표하기, 질문하기, 보고서 작성하기의 순으로 어려움을 호소하고 있는데, 이 역시 영어 강의를 위해서는 전반적인 영어 표현 및 이해 능력 향상 이 전제되어야 하며 무엇보다도 말하기, 듣기의 구어 능력 신장이 우선되어야 함을 재확인해 준다. 영어 강의 개선안에 대한 의견으로는 평가 방법의 다양성 및 융통성 확대, 영어 강의 수강을 돕는 전공 교재의 개발, 영어 강의 내에서의 교수-학생 상호 작용 증대, 국제교류의 기회 확대 등의 순으로 높은 반응을 보였다. 이는 향후 사범대학 영어 강의와 관련한 프로그램 개발에 시사하는 바가 크다. 즉, 영어 강의 평가를 결과 중심의 평가뿐만 아니라 과정평가와 수행평가에 초점을 두고, 영어 표현이 어려운 복잡한 사고 과정이 요구되는 경우 제한적으로 국문 반응을 허용하는 방안도 고려할 만하다. 또한 학습자들에게 좀 더 상세화된 강의 교재를 제공하고, 온·오프라인을 모두 활용하여 교수와 학생의 상호작용을 활성화할 수 있는 방안을 적극적으로 탐색할 필요가 있다. 아울러 학생들이 실질적인 국제교류가 가능하도록 다양한 교류 방안 함께 구체적인 강좌 개설도 요구된다.
