Formaldehyde induces not only irritation symptoms of eyes and respiratory tract but hypersensitivity reactions, such as contact dermatitis, allergic rhinitis, and asthma. To estimate the levels of exposure to formaldehyde during cadaver dissection in anatomy laboratory and to investigate the prevalence rates of irritation symptoms, allergic rhinitis and bronchial asthma, air concentrations of formaldehyde within cadaver dissection room were measured, and self-administrative questionnaire and enzyme linked immunosorbent assay(ELISA) were performed upon medical(n=182) and premedical students(n=69). For measurement of air formaldehyde level, chromotropic acid method(NIOSH method 3500) was used. Formaldehyde was conjugated to human serum albumin, and used as antigen in ELISA after identification of conjugation with immunoelectrophoresis. Prevailing symptoms during cadaver dissection were soreness of eyes or throat(92.9%), lacrimation(74.3%), rhinorrhea(49.7%), and sneezing(32.2%). Mean titers of IgE and IgG antibodies specific to formaldehyde-human serum albumin conjugate(F-HSA) of medical students were higher than those of premedical students. However, there was no case whose titers of anti-F-HSA antibody were higher than the twice of those of anti-HSA antibody or higher than the twice of the mean titers of premedical students. These results suggest that medical students were exposed to relatively high concentration of formaldehyde, but few asthma or allergic rhinitis were induced by formaldehyde exposure during cadaver dissection practice.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

Endotracheal intubation has been used widely for the maintenance of airway in the emergency patient and CPR in the acute airway obstruction patient and to treat respiratory insufficiency. Endotracheal intubation has many advantages but it may cause several complications which rate about 4% of endotracheal intubation patient. Among these complications, laryngeal granuloma is a relatively rare complication arising about 1 case per 10,000∼20,000 cases. Authors report a case of laryngeal granuloma which developed after endotracheal intubation required during emergency treatment. Case: A 55-year old female patient visited Chosun University Hospital Emergency Room complaining of dyspnea, cyanosis and sweating on Feb. 8th 1995. According to past history, she had a little obesity, dyspnea on exercise and mild hypertension. At arrival, blood pressure was 240/110mmHg, pulse rate 150 rates/min, respiratory rate 12/min, body temperature 36.5℃ and cyanosis with sweating on whole body was observed. And the mental state was semicoma. At 5 minutes after arrival, sudden respiratory arrest developed and immediate endotracheal intubation which emergency treatment was performed it was difficult to intubate endotracheally due to short neck and obesity. At 1 hour after arrival, general condition of the patient recovered well and extubation was done. The patient was transferred to internal medicine department and discharged after 12 days of medical treatment. At 2 months after discharge, the patient felt a progressive hoarseness and foreign body sensation of larynx. She was diagnosed as laryngeal granuloma at ENT department of Chosun University. She underwent the surgical operation and discharged in good health after 7 days of admission.

한국과 일본의 영어 교육 비교 연구 : A Historical Survey 한국과 일본의 영어 교육의 역사적 배경을 중심으로

ABTRACTThe present study surveys the historical background of English teaching in japan, which Korea inherited and has made its own tradition.The Japanese history of English teaching has had two periods during which English was popularly learned with the kind of enthusiasm that has not been seen in other times. One was the Meiji period When all subjects on the curriculum of the middle school and upwards were taught in English by Western teachers with books written in English, and the other the period of American occupation beginning with the end of the war, when the ability of spoken English was almost an essential condition for advancing one's career.In other times, the status of English was recognized only as one of the most important subjects of the examination for entrance into the university. This was a situation for which the grammar-translation method of teaching was the most effective, making it difficult for any communication-oriented method to be adopted in schools of formal educationThe national controversies, characteristic if English teaching in Japan, over whether English should be included in the curriculum of the middle school are traced partly to public dissatisfaction with the low level of English proficiency of high school and university graduates vis-a-vis the time spent on learning the foreign language,partly to nationalism of the Japanese people, and partly on the ideology of English education.English was introduced to Korea along routes different from the way it came to Japan. and had been taught to a small number of people by a communication-centered method until 1919, when Japan replaced with its own the traditional Korean educational system including English teaching. It can be said that English teaching in Korea actually started with the imposition of the Japanese educational system in Korea, and has thus inherited the Japanese tradition of English teaching. It is this historical background that makes the history and tradition of English teaching of Japan meaningful to us.It is revealed by this survey that progress in the teaching of foreign

This study si to compare the relative degrees of teachers' satisfaction between the situations before and after the operating of the the school governing committee(SGC). It is also to provide individual members of the school governing committee and teachers with basic information so that the school governing committee can be run and managed correctly in accordance with its original purpose. The result of the study showed that most teachers perceived wituation after the forming of the SGC was lower satisfaction than that of situation before. So We concluded that most teachers perceived they were impinged on their authority as educational experts after the oeprating the SGC.

대학의 새 교양영어 교과과정 편성을 위한 연구

조용남 건국대학교 교육대학원 1988 敎育論叢 Vol.10 No.-

The aim of this study is to provide reality-based grounds for critical reconsideration of the present university curriculum of English courses. A comprehensive study of the present state of the English language is made, revealing English as the actual lingua franca of the whole world in scholarship and science as well as in international communication. The traditional purpose and aim of English education are critically reviewed from the standpoint of the present state of the English language, supporting urgent need for its revision. An overview is also made of the state of English education in Korean universities and colleges, and the student's level of English achieved by it is found to fall far short of being of practical use. This unsatisfactoriness of the student's English is traced to, among others, the present university English curriculum. A proposal is made, as a remedy for the situation, that a new English curriculum be formed, one which divides the subject of 'General English' into the four specialized subject of Listening, Speaking, Reading and Writing, It follows that the number of curriculum hours of English has to be increased so that a student can elect to take one course in English a semester until graduation.

조남수,이경운,김용배 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

Our study was made on 96 cases of ketamine anesthesia, who visited to emergency department of Chosun university hospital. This patient was not controlled by verbal order and lidocaine anesthesia, and indication for the use of ketamine(from 1 to 5 years old). Dosage of ketamine in the intramuscular injection was 5mg/kg, in the intravenous injection was 2mg/kg. The results were as follows; 1. After the ketamine injected, expending time doing induction was for 2∼4 minutes in cases of intramuscular injection, and expending time doing induction was for 20∼60 seconds in cases of intravenous injection 2. After the ketamine injected, patient`s awake time was 50±5 minutes in case of intramuscular injection, and that is 20±5 minutes in cases of intravenous injection. 3. Injected ketamine caused increased blood pressure, pulse rate, and respiration rate, and saturation of oxygen was maintained 92-98% level. 4. In adverse effect, the presence of spontaneous eye opening, mild a groan, purposeless involuntary movement and increased excretion of saliva was appeared. 5. Advantage of ketamine injection was that one attendant was enough for restraining the patient, and reduced pain sense, and operator performed various procedures easily on stable condition. From the above results, it was considered in emergency department that indications for ketamine anesthesia are primary closure of simple facial laceration, burn dressing, and some diagnostic procedures( cardiac & ureteric catheterization, cystoscopy) in pediatric patients. It was considered, that all procedures should be performed under fullfill all the condition such as professional control devices(esp. central monitoring system) and basic CPR instruments and ketamine anesthesia-skilled doctor.

A clinical and laboratory study was conducted on 75 children with dysentery-like stool, who were admitted or visited to our pediatric department during 8 months period from January to August 1980. The following results were obtained: One to five years of age group was affected most frequently (47%). Shigella flexneri was identified by stool culture in 23 cases (30%) and Entameba hitolytica in 13 cases (17%). In bacillary dysentery group, fever was the most common symptom occuring in 83%, followed by abdominal pain in 35%, vomiting in 26% and convulsion in 22%. In amoebic dysentery group, fever was noted in 31% and convulsion in 8%, showing some contrast to the frequency of fever and CNS manifestation. About the character of diarrheal stools, 83% of bacillary dysentery group showed bloody, mucoid stool and 62% of amoebic dysentery group mucoid ones. Frequency of diarrhea was 11 times per day or more in 73% of bacillary dysentery patients, and 10 times per day or less in 92% of amoebic dysentery patients. The result of sensitivity test of isolated Shigella to various antibiotics were as follow: 100% sensitive to kanamicin, gentamicin, amikacin, cephaloridine and rifampin. 87% to nalidixic acid, and 4.3% to sulfonamide, chloramphenicol, streptomycin, tetracyclin, ampicillin and bactrim. And 22 out of 23 isolated Shigella strains revealed multiplydrug-resistance patterns to 6 or more antibiotics.

고속도강을 이용한 CFRP 복합재료의 드릴가공 특성

조규재,박종남,정용운 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.1

복합재료는 각 종 기계부품, 우주항공산업, 자동차의 내장재와 구조재, 건축구조물, 선박 재료, 스포츠용품 등 다방면에서 유용하게 사용되어지고 있다. 복합재료는 여러 가지의 대체 재료로서 타 산업에 비하여 활용의 가치가 높다. 그러나 기계가공분야에서는 가공의 어려움으로 인하여 활용도가 미흡한 상태이다. 따라서 본 논문에서는 CFRP를 수직형 머시닝센터에서 고속도강 드렬로 가공한 후 흘 가공 입 · 출구부에서 표면이 고르지 못함을 확인하였으며, 가공을 할수록 유동형의 긴 칩에서 분진형태로 변하는 칩의 형상 등을 관찰하였다. Composite materials are widely used in all kinds of machine parts, aerospace industries, internal and structural materials of cars, building structures, ship materials, sporting goods, and others. It is worth while to use the composite materials as various substitutions compared with others. But it is limited to use them in the field of the mechanical processing because of the difficulties in cutting. Thus it is proved that the surface roughness is in and out of the hole processing after cutting the CFRP with HSS drilling in the vertical machining center. And it is observed that the more it is processed, the more the fluid long chip is changed into the powdered chip.
