盧寬植,安東浩,鄭紀溶,金秉鎬,崔鳳洛,朴永寬 계명대학교 醫科大學 外科學敎室同門會 1990 남경 박영관 교수 정년퇴임기념 논문집 Vol.S No.-

The materials in this report were based on 22 cases of cystic hygroma which were treated in thi surgical department of the Presbyterian Hospital from January 1, 1961 to August 31, 1971. We also reviewed medical literatures, related to cystic hygroma. AlI cases were confirmed histopat-hologically. The following results were obtained. 1. Incidence of the cystic hygroma was frequents in infants (73%), and rare in above 35 yeaπof age (only 3 cases). The sex ratio was 1.2 for male to one for female. 2. The cardinal symptom and sign was palpable cystic mass in all cases. 3. The location of tumor was frequent in order as followings: posterior triangle of the neck in 25%, submandibular in 17%, supraclavicular, axillar, anterior chest in 12. 5%, respectively, flanks in 8. 3%, respectively, and upper arms in 4.2%. The location ratio was 1.2 for right to one for left. The most of them were located in the neck (15 cases). 4. The diagnosis of the cystic hyxgroma was relatively easy by previous history of tumor, clinical symptoms and signs, and physical examination. 5. The radical excision of the tumor was treatment of choice.

盧寬植,鄭鍾學 慶北大學校 醫科大學 1977 慶北醫大誌 Vol.18 No.2

1970年 1月 1日부터 1976年 12月 日까지 滿 7年間 大邱東山基督病院 一般外科에서 入院治療한 火傷患者 900名의 臨床記錄을 資料로 疫學的 側面에서 分析한 成績을 要約하면 다음과 같다. 火傷患者의 年令分包는 小兒患者가 62%였고 特히 1∼4才群이 36%로서 年令別 發生頻度의 差異가 뚜렷했고 男子가 女子에 비해 1.4倍 많았으나 性別年令別 差異는 認定할 수 없었다. 月別 發生頻度의 差異는 거의 없었으나 季節別로는 봄, 가을, 여름, 겨울의 순으로 차이를 나타내고 있었으며 하루중 時間別 發生頻度는 오후 6∼8時가 第一 높고 正午에서 午後 2時, 午前9∼11時 및 오후 3∼5時의 순으로 차이가 있었고 季節別 時間別 차이는 없었다. 火傷發生場所는 家庭內 火傷이 72%이고 家庭外火傷이 28%였고 農村보다 都市가 家庭內火傷이 많았다. 火傷原因은 熱湯傷이 58%, 火焰傷이 34%였고 都市는 熱湯傷이 많았고 農村에서는 火焰傷이 많았으며 季節別로는 熱湯傷은 봄에 많았고 火焰傷은 가을에 많았고 年令別로는 小兒에서는 熱湯傷이 많고 成人에서는 火焰傷이 많았다. 火傷의 深度는 電氣火傷과 火焰傷에서 深部火傷이 많아 火傷原因과 深度는 차이가 있었고 火傷範圍와 原因 및 火傷範圍와 深度間에도 차이가 있었다. 火傷部位는 全身 및 四肢火傷이 많았고 原因別 部位間에 차이가 있었다. 合倂症을 同伴한 例는 全體的으로 52%였고 創傷感染이 22%로 第一 많았고 火傷範圍와 合倂症은 比例했다. 火傷創面으로부터 細菌培養을 實施한 例에서 菌陽性이 65%였고 Pseudomonas가 第一 많았고 Sta-phylococcus 와 Enterobacter의 순이었고 潛血檢査陽性이 50%로 火傷範圍와 潛血陽性이 比例했다. 火傷患者의 致命率은 全體的으로 11%였고 火傷範圍와 年令에 比例했고 火傷原因別로는 火焰傷이17%로 第一 높았다. The followings are a summary of the epidemiological analysis of the clinical records in 900 burn patients admitted at the Department of General Surgery, Presbyterian Medical Center, Taegu, Korea for seven years from January, 1970 till December, 1976. Age distribution in burn patients showed that a total of 62 percent in all burns admitted were pediatric patients. The highest incidence in burns that was 36 percent of all patients, was found in the preschool age group (ages from one to four). Male patients were 1.4 times a many as female. However, when age and sex were considered together, no significant difference could be recognized. No monthly difference in the burn incidence was observed. However, seasonal differences could be recognized. In the order of decreasing incidence of burn, we found spring most frequently followed by fall, summer and winter. To the question of what time of a day sees most frequent burn accidents, the analysis showed most frequent incidence between 6 p. m. and 8 p. m., followed by between noon and 2 p. m. and between 3 p. m. and 5 p. m. in the decreasing order. When seasons and daily hours considered together, no significant difference was found. As for location in burn accidents, 72 percent of all the recorded burns took place at home, while the rest (28%) happened outside of home. There were more home accidents in the urban area than in the rural area. An analaysis of the causes in burn accidents showed that scalding burns are 58 percent in all burns and flame burns were 34 percent. Urban residents suffered from more scalding burns, while rural residents faced more flame bur accidents. In spring there were more scalding burns and in fall more flame burns. Most of pediatric burns were caused by scalding burn while adult burns suffered from flame burn. As for depth of burn injuries, flame and electric burn resulted in more full thickness burn. This means the causes of burn were closely related to the depth of injuries. Also a close relationship was found between the extents and the causes of burn, and between the extents and the depth of injuries. Upper and lower extemities were the most vulerable area attacked by burn injuries. Causes of burn injuries made differences in the location of burn. Fifty-two percent in all burns analyzed were accompained by some complications. The main complications were wound infection (22.2%), scar contraction (9.4%), airway obstruction (4.1%), septicemia (3.8%), curling's ulcer (3.2%) and renal failure (2.1%) in order. The larger the extent of burn injuries there were, the more complications we found. Detection of pathogenic organisms by culture taken from the burn wounds in 587 cases, positive rate was 65 percent. Out of these cultured organisms, we found Pseudomonas aeroginosa most, followed by Staphylococcus aureus, Enterobacter aerogene and E. coli in order. Positive reaction to occult blood test from the burn patients of 443 cases was 50 percent, showing extent of burn was in proportion to positive reaction to occult blood test. The case fatality rate due to burn injuries was 11 percent. The case fatality rate was closely related to the extent of burn and patient's age. Especially the flame burn patients showed the highest case fatality rate (17%).

有機燐劑 取扱者의 血中 Cholinesterase 値의 變化

盧寬植,李性寬,鄭鍾學 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

職業的으로 長期間 有機燐劑 農藥에 露出됨으로 해서 臨床的인 中毒症狀은 없으나 慢性的인 中毒이나 有害度를 파악하여 中毒을 豫防하고 作業環墳의 改善과 職業轉換을 誘導하는데 本硏究의 目的을 두었다. 1979年 6月부터 1980年 10月 사이에 勤勞者 定期身體檢査時期를 擇하여 農藥製造業體 勤勞者 112名과 農藥과 關係가 없는 職種의 勤勞者 81名을 對照群으로 有機燐劑露出者에 對한 吸收程度를 나타내는 指標인 血中 cholinesterase의 水準을 測定한 成績을 다음과 같이 要約한다. 赤血球의 cholinesterase値가 露出群은 平均 0.67ΔpH인데 비하여 對照群은 0.75ΔpH였고 血漿의 cholinesterase値도 露出祥이 平均 0.78ΔpH인데 비하여 對照群은 0.90ΔpH로서 赤血球나 血漿에서 다같이 對照祥에 비해 露出群의 cholinesterase抑制를 認定할 수 있었다. Cholinesterase의 抑制程度가 中毒症狀을 나타낼 程度는 아니라도 20% 以上 抑制된 例가 赤血球에서 露出群이 17.0%였고 對照群은 2.5%였으며 血漿에서 露出群이 48.2%인데 비하여 對照群은 7.4%로 有意한 差異를 認定할 수 있었으며 赤血球 보다는 血漿 cholinesterase 抑制가 더 顯著했다. 血液學的 및 生化學的 檢査에서 露出群과 對照群 사이에 뚜렷한 變化를 發見할수 없으며 正常範圍內에 있었다. 長期問 有機燐劑 露出者에 對해서는 週期的인 cholinesterase測定으로 中毒을 豫防할 수 있을 것으로 思料된다. This study was undertaken in order to prevent organic phosphate intoxication, to improve the working environment, and to recommend to transfer the work of the people who were chronically exposed to organophosphorous pesticides but who do not show any clinical symptoms. Blood cholinesterase activity value which is and important indicator of absorption of the organophosphorous pesticides was measured in 112 exposed men who worked at organic phosphate industry, and in 81 men as controls who worked at other industries, and were not exposed to these pesticides from June, 1979 till October, 1980. The results are as follows: Mean value of RBC cholinesterase activity was 0.67ΔpH in the exposed group and 0.75ΔpH in the control group, respectively. Mean value of plasma cholinesterase activity was 0.78ΔpH in the exposed group and 0.90ΔpH in the control group, respectively. There were significant differences in cholinesterase activity levels in RBC and plasma between exposed and control groups (p<0.001). Both RBC and plasma cholinesterase activities were significantly diminished in the exposed group compared to control group. Subjects with lower blood cholinesterase activity did not show any clinical symptoms of organic phosphate intoxication. However, percentage of subjects who showed to be decreased to 20% or more of the RBC and plasma cholinesterase activities was higher in the exposed group(17.0% and 48.2%, respectively) than in the control group(2.8% and 7.4%, respectively). Cholinesterase activity in plasma was decreased more profoundly than that in RBC. There were no significant differences in hematological, and other biochemical parameters between exposed and control groups. In persons who were occupationally exposed to organophosphorous pesticides for a long period, blood cholinesterase activity determinations should be made periodically in order to prevent organic phosphate intoxication.

가상 공간 하에서의 대학생들의 함수개념 변화에 관한 연구

노관식 한국교육정보미디어학회 1999 교육정보미디어연구 Vol.5 No.2

이 연구는 실시간 및 비 실시간 컴퓨터 매개 통신(Computer Mediated Communication [CMC]) 체제를 이용한 가상 공간 환경 하에서 대학생들의 수학 함수 개념의 변화를 관찰 기록하였다. 네 명의 애리조나 주립대 학생들이 두 명씩 짝지어서 가상 공간 하에서 한달 정도에 걸쳐 함수문제들을 풀었다. 원안분석 방법을 통해 학생들의 함수개념 변화에 대한 기록들이 수집분석 되었다. 연구결과 학생들의 잘못된 또는 제한된 함수개념들은 대부분 변화되었다. 학생들의 개념은 일관성 있게 변하지 않았고 확고히 정립된 개념은 쉽게 변화되지 않았다. 학생들의 몇몇 제한된 개념들과 잘못된 개념은 학생들의 함수에 대한 이해에 중대한 역할을 하였다. 마지막으로, 이 CMC 체제의 소집단 수학 함수개념 학습에의 적용 가능성을 확인하였다. This study observed and documented the changes of the college student's notion of mathematics functions in a virtual environment that integrated a synchronous and asynchronous Computer Mediated Communication system. Four Arizona State University undergraduates were teamed into pairs and solved function problems in the virtual classroom over a one month period. A protocol analysis method was used to analyze the collected data on the student's conceptual change of the function mncept. The study found that most of the students limited conceptions and misconceptions were changed. Student's conceptual change did not follow a linear pattern, and the change did not occur eady especially when the notion of functions was well established. Some of the students hited conceptions and misconceptions of functions were interrelated. A notion, a function problem should make sense, played an important role in the development of students function concept. Finally, students corrected most of their incorrect conceptions regarding the notion of functions. This means that college students could learn through interactions in ths type of virtual learning environment.

Inquiry on the Potential of Word Processor to Enhance the Writing Processes of Students with Learning Disabilities

Rho, KwanSik 한국교육정보방송학회 2001 교육정보미디어연구 Vol.7 No.1

이 논문은 워드 프로세서가 학습장애 학생의 작문향상에 어떻게 이용될 수 있을 가를 작문의 3 단계(흔히 시작, 전이, 검토단계로 나뉨)에 걸쳐 논의하였다. 학습장애 학생은 학습활동의 기초 능력인 글 쓰기와 읽기에 문제를 갖고있으며 이러한 기초능력의 부족은 그들 학습의 전반에 걸쳐 영향을 미친다. 글 쓰기 시작 단계에서 워드 프로세서는 글의 소재를 생산하고 정리하는데 도움을 제공한다. 전이 단계에서는 작가의 생각을 쉽게 옮겨 적게 하고 쓴 내용을 가지고 작가의 의도에 따라 실험하고 재구성하기 쉽도록 하는 워드 프로세서의 기능으로 인해 학습장애 학생의 작문과정을 용이하게 한다. 검토단계에서 워드 프로세서는 글 쓰기에서의 단순 반복작업 및 고도의 정신능력이 요구되는 글의 수정 과정에 큰 도움을 제공한다. 글의 내용을 명료히 보여주는 워드 프로세서의 기능은 글 쓰기의 모든 단계에서 자신의 글 내용을 반성하고 타인에게 보여주어 의견을 수렴하게 하는 방법을 통해 유용하게 활용 될 수 있다. 작문단계에서 적절히 활용될 수 있는 여러 소프트웨어의 사용은 학습 장애 학생을 위한 작문 수업의 계획시 고려할 필요가 있다. 워드 프로세서 기능의 적용은 작문수업을 위한 교수-학습 전략과 함께 적합하게 사용될 때 보다 큰 효과를 볼 수 있다. The purpose of this paper is to discuss how a word processor can be used in writing instructions for learning disability. A word processor can effectively be used in three phases of writing such as planning, translating, and reviewing. In the planning stage, students produce ideas for writings and they can use a word processor for this activity. In the translating stage, students can use the program for transferring their ideas into writings, and structuring and restructuring their writing easily. In the reviewing stage, the program helps students by reducing their burdens of simple and repeated writing activities. Students can spend their time and efforts on the higher level of cognitive activity such as changing the macro-structure of their writings. The effect of using a word processor for a writing instruction can be maximized when appropriate writing strategies are applied together
