火에 대한 槪念은 內經에서 言及한 이래 生理, 病理, 運氣的인 側面에서 여러 醫家들에 의해 多樣하게 解析되어지고 있다. 특히 古來의 理論에 얽메이지 않고 豊富한 臨床經驗을 바탕으로 李東垣은 脾胃論의 主要內容으로 '陰火論'를 主張 하였고, 朱丹溪는 歷代 醫家들의 火에 對한 槪念을 整理하여 '相火論'과 '陽常有餘 陰常不足論'을 主張하여 모두 獨特한 火의 理論을 集大成하였다. 後代에 命門學說이 나오기까지 重要한 理論·臨床的 資料를 提示하여 明代의 溫補派와 滋陰派로 集約되어 繼承되어진 東垣의 陰火와 丹溪의 相火에 대하여 歷史·環境的 背景, 槪念, 生理, 病理 및 治法 等을 諸文獻을 通하여 比較 檢討하였다. Through studing historical and environmental background, definition, physiology, pathology and therapy of Li DongWon' theory, Yin-fire, and Zhu DanXi's theory, ministerial fire, the conclusions were obtained as follows. 1. Yin-fire was a expression of debilitating heat induced by shortage of primordial Qi, even though excessive syndrome came out. 2. Ministerial fire is based on the motive power of bowel visceral activity and maintenances of life in physiology. But it is also the noxious factor that means it is the enemy of primordial Qi in pathology. 3. The etiology and pathology of Yin-fire was explained by the deficiency of spleen and stomach's vital energy caused by irregular food, overstrains and emotional stress. 4. It was thought that ministerial fire was caused by excess of emotion, fatty food and sexual intercourse and among theses factors (that gave rise to fire of bowel, visceral and Osungguelyang(五性厥陽), excessive emotion was the most important part. 5. The syndrome of yin-fire were consisted of two groups, ie. damp heat and deficiency of vital energy syndrome. And the syndrome of pathological ministerial fire is similar with the syndrome of fire among Nei-Ching's 19 pathologies, which is rapid and various. 6. Dong-Won emphasized the treating method of supplementing digestive tract and ascending yang by using sweat and warm herbs according symptom. In the other hand, DAn-Xi emphasized the treating method of nourishing yin and relieving fire by using bitter and cold herbs.

신동천,이순영,정상혁,원종욱,박종세,박송자 大韓産業醫學會 1994 대한직업환경의학회지 Vol.6 No.2

In order to ascertain the status of health damage among Korean farmers who spray pesticides regularly in summer, blood and urine samples were collected for 88 volunteers during July to September in 1990. Serum cholinesterase activity, parent compounds of pesticides in blood and urine, SGOT, SGPT, blood pressure, pulse rate were measured. The results were as follows; 1. Mean cholinesterase activity after spraying pesticides was significantly lower than that before spraying. While proportion of abnormal cholinesterase activity(<1990 U/L) group was 2.3% before spraying pesticides, the proportion of the group after spraying was 22.8%. 2. Cholinesterase activity were decreased over 50% in 14.7% of the subjects who can be classified into poisoning group 3. While pulse rate and blood pressure were slightly increased in poisoning group, those were significantly decreased in non-poisoning group. 4. Consecutive spraying of pesticide caused further reduction of cholinesterase activity. 5. Five parent compounds of pesticides frequently used during summer farming were analyzed using 106 blood samples. IBP in one sample and Isoprothiolane in four samples were detected. No parent compounds were detected in urine samples.

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.

이동환,송창수,강경욱 울산대학교 1991 공학연구논문집 Vol.22 No.2

地面板위에 모양이 서로 다른 복수 장애물을 바람의 방향과 수직으로 배열(Side-Side)하여 액체4염화 티타늄을 관찰대상 표면에 직접 도색하여 유동장을 효과적으로 가시화 하였다. 장애물 사이의 간격이 좁아지면 틈을 통과하는 흐름은 어느 한쪽으로 傾斜진다는 특징이(Biased Flow) 확인되었고, 지면판위 박리선, Necklace Vortex, 후류등 3차원 유동장 특징이 확인되었다. Flow patterns around two-bluff bodies in side-by-side arrangements on the ground plane are easily visualized using liquid titanium tetrachloride. In two-dimensional flow field, the gap flow between two-bodies became biased to one side for closer spacing. Three-dimensional flow patterns, which have seperated regions, necklace vortices and other dynamic seperations, are dependant on the bluff-body shape and the gap-space ratio.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

Bacteriocins are proteins produced by heterogeneous group of bacteria that have a bactericidal effect on closely related organisms. Recently, bacteriocins from lactic acid bacteria(LAB) and other food-related organisms have been the subject of much research of their potential as food biopreservatives. The goal of this study were to isolate LAB from commercial fermented fish products and identify their bacteriocin activity. All bacteriocin-producing isolates were identified as LAB. The NK24, NK34, and SA72 isolates were as identified as Lactococus lactis subsp. Lactis where as SA131 isolate was Lactobacillus brevis according to database of API50 CHL kit. All antimicrobial substance(s) produced from 4 LAB isolates were lost their antibacterial activity completely by treatment of some proteases, which indicate its proteinaceous nature. The bacteriocins produced from NK24, NK34, and SA72 isolate showed broad spectrum of activity when compared to SA131 bacteriocin.

이선웅,고동희,진구원,박동욱,이정탁,송윤희,이상윤 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.1

서론: 과민성폐장염의 원인물질로 금속가공유는 외국의 경우 작업장의 집단발병 사례들을 중심으로 많은 보고가 되어 왔으나 우리나라에서는 아직 보고되지 않았으며,저 자들은 금속가공유에 1년간 노출된 근로자에서 발생한 과민성폐장염 1예를 발견하였기에 작업환경측정을 시행한 후 작업관련성을 평가하여 보고하는 바이다. 증례: 64세 남자 환자가 1년간 강관을 절단하는 작업을 한 후 호흡곤란을 주소로 내원하였다 노출력,임상적 소견 및 방사선학적 소견을 토대로 과민성폐장염으로 진단되었다. 작업환경 측정결과 공기 중 금속가공유,엔도 톡신,총 세균 및 곰팡이는 각각 0.531 mg/m³, 6.33 EU/m³ 100 CFU/m³ 및 75 CFU/m³이었고,금속가 공유 내 엔도톡신,총세균 및 곰팡이는 각각 1.5x10⁴EU/mL,4.6x10^(5) CFU/mL 및 1.8×10^(5) CFU/mL이었다. 고찰: 금속가공유 내의 원인항원에 대한 침강항체를 검사하지 못했으나,작업환경 측정결과 금속가공유가 일반적인 허용가능 수준 이상으로 오염되었으며,기존의 과민성폐장염 발생 사례들과 비슷한 수준 또는 그 이상으로 오염되어 있었다. 공기 중 금속가공유 농도 역사 NIOSH의 REL과 ACGIH의 NIC를 초과하고,기존의 사례들에 비해서도 대체적으로 높은 수준 이었다. 금속가공유 이외의 다른 원인에 대한 감별과 기존의 발생사례들과의 노출수준 비교를 통하여,저자들은 환자가 금속가공유에 의한 미생물 항원에 노출되어 과민성폐장염이 발생한 것으로 판단하였다. Introduction: There have been no reports of hypersensitivity pneumonitis caused by metal working fluids in Korea, despite their existence in other countries. Here, we report the first such case, along with an assessment of work-relatedness through exposure assessment. Case report: A 64-year old male patient visited the hospital with dyspnea after metal pipe cutting for about a year. He was diagnosed with hypersensitivity pneumonitis from the evidence of specific exposure history, clinical symptoms, and radiologic findings. The air exposure levels of the oil mist, endotoxin, total bacteria and fungus in the work environment was TWA(8-hr) 0.531 mg/m³, 6.33 EU/m³, 100 CFU/m₃ and 75 CFU/m³, respectively. The concentrations of the endotoxin, total bacteria and fungus within the metal working fluid was 1.5 X 10⁴EU/mL, 4.6 X 10^(5) CFU/mL and 1.8 X 10^(5) CFU/mL, respectively. Discussion: Although the patient did not receive a specific precipitating antibody test, the microbial concentration within the metal working fluid was higher than normal and similar to previous case reports, The oil mist level in the air exceeded the NIOSH REL and ACGIH NIC, and were similar or higher than previous cases. By excluding other causes of hypersensitivity pneumonitis, we concluded that the disease developed from exposure to microbial antigens in the metal working fluid.
