경제 성장과 더불어 교통수단의 발달과 취미 활동에 대한 높은 관심과 함께 교통사고, 스포츠 등의 레저 활동, 폭력 등에 의하여 악안면부의 외상은 빈번하게 발생할 수 있다. 1996년 1월부터 1996년 12월까지 1년간 본과에 내원한 악안면부 외상 환자 중 상악골, 하악골, 관골 등의 악안면골 골절을 동반하지 않고 주로 치아 손상을 주소로 이에 대한 치아 고정술을 시행한 환자 43명에 대하여 의무 기록과 방사선 사진 등의 자료를 참고로 하여 영구치의 손상과 치아 고정술의 예후에 대하여 평가하여 다음과 같은 결론을 얻었기에 추후 영구치 손상 환자에 대한 치료술식과 예후 판정에 참고로 하고자 문헌 고찰과 함께 보고하는 바이다. 1. 치아 외상은 여자보다 남자에게서 더 많이 발생하였다. 2. 치아 외상을 받은 호발 연령은 10대와 20대였다 3. 치관 외상의 주된 원인은 낙상, 교통사고와 운동 순이었다. 4. 치아 외상시 가장 호발부위는 상악 전치부였다 5. 치아고정시 아치 바와 강선을 이용한 방법과 강선과 치과용 레진을 이용한 방법의 예후에는 큰 차이가 없었다. 6. 치아고정시 가장 큰 병발증은 치아 실활에 따른 신경치료, 치근 흡수, 발치였다. The injuries of the offal and maxillofacial region occrurred frequently because of the accidents, sports and violences. The authors experienced the injuries of the teeth that did not involve the bony fracture of the maxillofacial bones. We reviewed the 96 teeth of 43 patients that were fixed after replacement and/or replantation of luxated teeth during 1year(1996). We analysed and evaluated the treatment methods and the prognosis of the fixated teeth using the hospital records and radiographies. The results were as follows. 1. The occurrences of teeth injuries were more frequent in male than in female 2. The prevalent age groups were the second and third decades. 3. The major etiologies of teeth injuries were fall-down, traffic accidents and sports. 4. The prevalent teeth injured area were the upper anterior teeth area. 5. The prognosis of the teeth fixation methods between arch bar with wiring and wire with dental resin were not different significantly. 6. The major complications were the endodontic treatment due to discoloration and/or non-vitalization of teeth, root resorption and extraction of injured teeth.

임경옥,김수영,이양현,이선우,김정란 大韓神經精神醫學會 2006 신경정신의학 Vol.45 No.6

Objective : This study was conducted to develop and to validate the Korean version of Delirium Rating Scale-Revised-98(K-DRS-98), which is a scale for diagnosing delirium and evaluating its severity. Method : After developing the K-DRS-98, 102 patients were rated by it among 4 diagnostic groups, such as delirium (N=25), dementia (N=27), schizophrenia (N=25) and others (N=25). To test for reliability, K-DRS-98 was independently administered by two psychiatrist. To test for validity, Korean version of Mini-Mental State Examination (MMSE-K) and Clinical Global Impression (CGI) were administered simultaneously. Statistical analysis was done with SPSS window version 12 package and statistical significance was p<0.05. Result : Intemal consistencies (Cronbach α) of two raters were 0.867 and 0.858, respectively. Inter-rater reliability (κ) was 0.893 for severity items of K-DRS-98 and κ value of diagnosis items was 0.969. In Delirium group, Pearson correlation Coefficients (r) of K-DRS-98 were -0.682 for MMSE-K and 0.667 for CGI. In comparison Delirium group with Others, ANOVA post hoc multiple comparison LSD was statistically significant (p<0.001). The cutoff score to diagnosis of delirium can be recommended 16 for seventy items and 21.5 for total score, respectively. Conclusion : The K-DRS-98 was showed good reliability and validity for the assessment of delirium. The K-DRS-98 is an easy and useful tool for diagnosing delirium and assessing its severity.

임영,한진구,김지홍,김현욱,김은경,김경아,장황신 大韓産業醫學會 1999 대한직업환경의학회지 Vol.11 No.3

Objectives : This study was designed to evaluate cytotoxicity of TAFMAG, which is a trade name of natural mineral fiber mined and produced in China. Methods : The cytotoxicity of TAFMAG was evaluated by measuring iron content, lipid peroxidation, erythrocyte hemolysis, and cytotoxicity in vitro. These results were compared with the data of chrystotile and wollastonite as a positive and negative control, respectively. Results : There was significant increase of Fenton activity in TAFMAG and chrysotile with dose-response pattern. The iron chelating agent, desferrioxamine, significantly decreased Fenton activity of the particulates except wollastonite. TAFMAG and chrysotile fibers significantly increased malondialdehyde concentration from lipid peroxidation of the red blood cell membrane. In erythrocyte hemolysis test, TAFMAG & chrysotile had stronger effect on erythrocyte hemolysis than wollastonite with the concentration of 1,000g/ml. Furthermore, TAFMAG was more hemolytic than chrysotile with the concentration of 5,000g/ml. There was a significant cytotoxic effect in TAFMAG and chrysotile on RAW cell compared with wollastonite. Conclusions : In vitro study suggested that TAFMAG may have a similar health hazard as usual asbestos.

임경호,남철현 慶山大學校 保健福祉硏究所 1999 保健福祉硏究 Vol.3 No.-

This dissertation is focused on understanding of the various elements and problems influencing on the practical condition of health education and behavioral pattern of middle and high school physical education teachers as well as on providing beneficial materials for developing health education programs. for these purposes, from August 12th to September 12th in 1988, a survey was made by asking 173 middle and high school physical education teachers working at Taegu and Kyoungbuk area. The followings are the summary: 1. Of all the respondents, male teachers were 84.4%; 30 to 39 year-old teachers, 56.4%, more than a half of all respondents. 40.5% of them said they have no religions; 89.6%, not married; 50.0%, from small cities; 83.2%, in middle class 80.5% of them were from national teacher's schools; 63.0%, from others; 74.0%, working at national or public schools. 31.8% said they had been working for more than 6 to 10 years. 2. Of the respondents, 83.2% knew there are departments and graduate schools about health education in Korea and those who had the experience of having taken health education courses were 51.8%-94.4% took the course before 29 years old; 72.2%, before marriage; 80.0%, under 1 to 5-year-working experience as school teachers. The percentage of respondents who had never been trained about health education amounts to 74.6%, and their sources for gaining information and knowledge about it were newspapers(24.9%) or technical magazines(24.3%). 3. The survey showed that 97.7% of the teachers felt the necessity of health education, and 92.5% said it should be put into school curriculum. In that case, 53.2% said 1 to 5 classes of all should be assigned for health education. Appropriate ages of sex education, said 52.0%, should be in higher grades of elementary schools. 45.1% said the teacher fit for the health education is a nurse-teacher; 32.4%, a professional teacher; 22.5%, school physical education teacher. And the more teaching experience they had, the more necessities of health education teachers they were aware of. 4. Those who brush their teeth after each meal were 52.0%; who wash their hands after coming out of the toilet, 56.1%; who think of their own physical conditions as normal, 55.5% and as fat, 29.5%, as healthy, 56.6%; who were doing exercises, 84.4%; who were almost not doing exercises, among the female teachers, 55.6%; who had never been absent from schools for the disease for the past one year, 88.4%. And 49.7% of the males were smoking (female, 3.7%), a pack of cigarette a day, 33.5% and a half pack, 16.2%, 78.6% said they drink alcohol, and 36.4% of them drink once a week. 41.8% of male teachers drink once a week; 21.9% of females, once or twice a month. 5. Those who think there should be health-developing facilities at schools were 74.6%, and 43.9% thought it is necessary to have a room for exercise facilities in an appropriate size. 6. Most of the teachers thought the students were satisfied with their teaching, and 48.0% said the students were getting weak. Judging from the facts above, as health education is not formal curriculum at school, it would be necessary to lead teacher's knowledge about it to a reasonable way through athletics classes closely related to health education. There should be a change of consciousness about health education by training teachers practically. Moreover, it would be beneficial for developing school education and students' health to have professional teachers in each school or to select health education in curriculum.

임경욱,이광희,라지영,이동진,안소연,김지영,송지현,김윤희 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

연구목적은 중증 유아기 우식증에 대한 두 개의 정의를 진단 기준으로 하였을 때 각 기준에 따른 유병률이 일치하는 정도를알기 위함이었다. 연구대상은 익산시 어린이집 중에서 무작위로 추출한 7개 어린이집의 36개월 이상 71개월 이하 어린이401명 이었다. 치경과 탐침을 사용한 구강검사를 통하여 치아별 우식경험유치면 (dmfs)의 수를 조사하였으며 . 중증 유아기 우식증의 진단 기준은 (1) 상악 전치에 1개 이상의, 와동이 형성된 우식,상실(우식증에 의한), 충전 평활면이 있거나 (2) 우식,상실,충전 치면의 수가 3세는 4개 이상.4세는 5개 이상.5세는 6개 이상인 경우로 하였다. 상악 전치부 우식증에 의한 우식유병률과 우식경험유치면수(dmfs)에 의한 우식유병률은 3세에서 각각 26.7%. 28.9%, 4세에서 각각 32.4%, 30.4%, 5세에서 각각 39.4%, 41.3%, 전체에서 각각 35.4%, 35.9%으로서. 연령별로는 약간의 차이가 있었으나 전체에서는 차이가0.5%로서 거의 일치하였다. 따라서 중증 유아기 우식증의 진단은 두 가지 기준 중에서 어느 하나를 사용하더라도 비슷한 결과가 나을 것이라는 것을 확인할 수 있었다. The purpose of study was to compare the prevalences of severe early childhood cahes(S-ECC) using two different diagnostic criteria. The subjects of this study included 401 preschool children from 36 to 71 months of the randomly selected seven nurseries in Iksan city. Severe early childhood caries was defined as (1) 1 or more cavitated, missing (due to caries), or filled smooth surfaces in primary maxillary anterior teeth or (2) a decayed, missing, or filled score of ≥4 (age 3), ≥5 (age 4), or ≥6 (age 5) surfaces. The prevalence determined by maxillary anterior caries and the prevalence determined by dmfs were 26.7%, 28.9% in 3 years, 32.4%, 30.4% in 4years. 39.4%, 41.3% in 5 years, and 35.4%, 35.9% in all, respectively. The results suggest that the two diag-nostic criteria of the severe early childhood caries yield almost the same results.

The Ultrasonography is rapid, mobile, and noninvasive diagnostic tool in emergency center. As a result, we estimate it`s value as an advocated primary diagnostic modality in the immediate evaluation of patients with multiple trauma. We investigated 60 patients with traumatic hematuria(microscopic hematuria or gross hematuria) who visited our emergency department from 1995, July to 1996, March. To evaluate the injury of urinary systems, emergency physician examined patients with hematuria by ultrasonography, and comapared the results with those of excretory urography and computed tomography. We demonstrated 21 positive findings for abnormal fluid collection and renal parenchymal injury and bladder rupture on ultrasonography. All bladder injuries were diagnosised by ultrasonography, and all major renal injury(grade Ⅲ,Ⅳ,Ⅴ) were also diagnosised by that. The accuracy of emergency ultrasound examination in traumatic hematuria was 97.0%, and sensitivity was 95.0% with specificity of 97.4%. The ultrasonography was an accurate diagnostic adjunct in detecting renal injury and bladder injury in traumatic hematuria patients. Ultrasonography provides an excellent noninvasive diagnostic tool for the initial screening study of patients with traumatic hematuria.

The need for rapid diagnosis and treatment of life-threatening thoracic and intra-abdominal injury result in controversy over the appropriate triage of unconscious blunt trauma patients. To aid in early decisions for these patients, a prospective analysis of 98 patients with glasgow coma scale(GCS) scores≤8 was undertaken. Although intra-thoracic and intra-abdominal injuries were frequently identified based on systolic blood ressure, the use of clinical signs alone resulted in more missed injuries than did using the emergency ultrasonography. In normotensive patients(n=34), intra-thoracic injuries was identified in one patient(2.9%), and intra-abdominal injuries were in 7 patients(20.6%). In shock(systolic blood pressure<90mmHg) Pa-tients(n=64), thoracic injuries and intra-abdominal injuries were diagnosed in 8(12.5%) and 27 patients(42.3%), thoracic and abdominal combined injuries were identified in 11 patients(17.2%). The sensitivity, specificity, and accuracy of emergency ultrasonography were 96.3%, 91.7%, 94.9%. This study suggests that all unconscious trauma patients undergo immediate emergency ultrasonography to prevent missing life-threatening injuries.

In the guidelines of Advanced Trauma Life Support(ATLS), essential plane roentgenograms (chest AP vIew, cervical spine lateral view and pelvis AP view) are recommanded when primary survey and resuscitation phase are finished in care of multiple injured patients. A prospective study was carried on 376 multiple trauma patients who admitted to Wonju Christian Hospital from July, 1995 to October. We analyzed clinical significance of essential X-ray in multiple trauma patients, and classified the patients by their status of mentality. The one is alert group when their Glasgow Coma Scale(GCS) is over 13 point, the other is disoriented mentality group when their GCS are below 12 point. The alert group was redivided by presence of clnical symptoms and/or signs, and clinical significances of essential X-ray were analyzed. Among the 376 patients, 330 patients are alert group that their GCS score is over 13 point and 46 patients are disoriented group who's GCS were below 12 point. The detection rate of abnormality in essential X-ray is higher in disoriented group than alert group(cervical-spine lateral view : 13.5% vs 3.0% cheat AP view : 0.4%, pelvis AP view : 0%). This study suggests that their are no needs of taking essential X-ray in patients who is alert in mental state and have no clinical symptoms and/or signs.
