치과기공실의 작업공정별 소음에 관한 연구

조수열,남상룡 효성여자대학교 부설 한국환경위생연구소 1992 환경위생연구 Vol.2 No.1

본 연구는 치과기공실의 작업부서별, 1인작업시의 소음도를 조사하여 기본자료로 하고 복합공정시의 소음을 측정하여 70 dB이상의 소음 노출시간을 조사함으로서 전체 치과기공실의소음도를 추정하고, 치과기공실의 소음이 치과기공사에게 정신적, 정서적 , 생리적으로 어떠한영향을 미치는가를 설문조사하여 소음에 노출되어 있는 치과기공소의 환경위생 관리와 건강장해를 예방하기 위한 기초자료를 얻고자하는데 그 목적이 있으며 그 결과는 다음과 같다. 1. 작업부서변 1인 공정시 소음도는 각 작업부서별 모두 연마작업시 높은 수치를 나타냈으며, 그 정도는 70 dB이상이다. 2. 작업부서별 복합공정시 공정별 소음도는 1인 작업공정시보다 전체적으로 소음발생이증가하였는데, 소음도의 차이는 연마시보다 조용한 작업공정 시가 최소한 10 dB이상으로더 큰 차이가 나타났다. 3. 작업부서별 소음 노출시간은 80 dB이상에서는 복합공청시 도재기공부서(150분), 국부의치(120분), 관교의치기공(100분), 총의치기공(80분) 순으로 나타났다. 4. 작업실의 시간대변 소음정도는 연마작업시는 대부븐이 80 dB이상이고 Wax작업시는대부분이 75 dB이하로 나타났다. 5. 설문조사에서 치과기공사의 심리적 상태는 기공실 소음으로 인하석 거의 매일 짜증난다(14%), 가끔씩 짜증난다(29%)로 나타났고 정서적 불안감도 화가 잘 난다(19%)로나타났다. 6. 소음이 치과기공사의 신체에 미치는 영향은 기공일을 하는 동안 위장병에 대해서는위산과다 39%, 위궤방 11%, 위염 5%, 십이지궤양 3% 순으로 나타났고, 심장이 약한것 같다가 32%로 나타났다. 7. 소음이 치과기공사의 청력에 미치는 영향은 약해진다가 39%, 보통이다 33%, 정상이다14%로 나타났다. 치과기공실에서 발생되는 소음에 의해 치과기공사들이 심리적, 신체적으로 큰 영향을 받는것으로 나타났으므로 치과기공실의 작업환경관리에 대해 보다 많은 관심이 요구되며, 소음의발생을 줄일 수 있는 지속적인 연구가 요망된다. Degree of noise by personal dental laboratory working process anddegree of noise by complex dental laboratory working process were measuredseparately. The time of exposure to noise greater than 70 dB estimated on thebasis of afore-medntioned information. Questionarire were employed to investi-gate the mental, emotional and physiological effects of noise on dental techni-cians. The purpose of this study was to provide basic information on keepingdental technicians who are exposed to noise pollution in good working conditionand good health. Results obtained are as follows ; 1. Polishing process in each working part showed high degree of noisegreater than 70 dB in terms of degree of noise by personal working. 2. Degee of noise by complex working process in each workong part wasgreater than that of personal working process. 3. Time of exposure to noise complex working process the part of porcelain150 min., partial denture 120 min., crown and bridge 100 min., full denture80 min. 4. Degree of noise by time in dental laboratory was 80 dB in general forpolishing process and below 75 dB for waxing process. 5. Effects of noise on mental and emotional state of dental technicians she-wed that they felt irritated every day(14% ), irritated once in a while(39% ) andeasily get med(19% ). 6. Effects of noise on heart and stomach were hyper-gastric acid(38% ) ,gastric ulcer(11% ), gastritis(5% ), deuodenal ulcer(3% ) and weak hert function(32% ). 7. Effects of noise on the hearting ability were weak(39% ), moderate(33% )and normal(14% ). Data presented in this study demonstrated that noise in the dental laboratoryexerts profound effect on detal technicians mentally, physiologically and emotio-nally. In light of the above results, therefore, it appears advisable to devote subs-tantial interests on the management of working condition and put further(conti-nuing) effeorts in the ivestigation for reducing noise problem.

Collarless 도재전장주조관의 제작 방법에 따른 치경부 변연적합도에 관한 연구

조수열,장기환,임시덕,주경삼 한국위생과학회 1997 한국위생과학회지 Vol.3 No.1

The purpose of this study was to evaluate the marginal gap in the collarless ceramo-metal restoration by the different techniques and materials. Three ceramic materials were used : 1) Vita porcelain 2) Ceramco porcelain 3) Vita porcelain and margin porcelain technique, wax technique, and LCS technique. The results were as follows : At point A, the marginal adaptation in case of Vita porcelain by LCS technique was best ㎛ and its marginal gap was 59.9 ㎛ At point B, the marginal adaptation was best in case of Vintage porcelain by margin porcelain technique and its marginal gap was 60.0 ㎛ at point B. At point C, the marginal adaptation was best in case of Vita porcelain by wax technique and its marginal gap was 60.1 ㎛.

조수열,백경연 한국위생과학회 1997 한국위생과학회지 Vol.3 No.1

Survey persons of the rearch were categorized by age. There were 111 between 20-29 (38.9%), 104 between 30-39 (36.5%) and 70 between 40-49(24.6%). The subjects of the research were also categorized by occupation. These were 181(63.5%) of field worker and 104(36.5%) of office worker. To the question of having any regular exercises and clinical histories 224(78.8%) answered they have no exercises regularly and 242(84.9%) answered that keep commonly good conditions an without any clinical histories. To the question of eating with the respect of time and place over two days, 173 workers(60.0%) had breakfast at home however, 258 workers(90.5%) had lunch provided by their factories and 158 workers(55.4%) had dinner in the working places. The study of the condition of nutritive intake showed that only 7.7% of whole population took enriched food in accordance to recommended dietary allowance. In the survey of intake of dairy products, 27.4% of whole workers answered to take a cup of milk everyday. Intake of vegetablewas mostly done during lunch and dinner. Intake of carbohydrate was mostly done not through potatoes and sweet potatoes but through cooked-rice. Potatoes and sweet potatoes were much less taken than the recommended dietary allowance for a day.

환경오염물질 중독과 영양소의 관계

조수열 嶺南大學校 環境問題硏究所 1989 環境硏究 Vol.8 No.2

영향상태가 좋고 나쁨에 따라 질병현상에 현저한 차이가 있듯이, 환경오염물질의 중독에 있어서도 이 원칙은 적용된다. 그러나 인간의 경우, 영양소와 환경오염물질 중독의 관계는 대단히 복잡하여 기전(mechanism)을 해명하는 데는 다방면에서의 상세한 연구가 필요하다. 이에 가장 유력한 방법인 동물실험에 관해 몇가지 항목으로 나누고, 주로 Cd, Pb과 PCB 및 Pesticides등에 관한 연구를 중심으로 하여 논하고자 한다.

갈근 물추출액이 흰쥐에 있어서 Benzo(a)pyrene 에 의해 유도된 간장해에 미치는 영향

조수열,윤수홍,이윤경 한국위생과학회 1995 한국위생과학회지 Vol.1 No.1

The present study was conducted to evaluate the hepatoprotective effect of puerariae Radix water extract an benzo(a)pyrene(B(a)P)-induced liver injuries in rats. In vitro experiment, primary cultured hepatocytes(5 × 10&^5 cells/ml) were cultured for 20-24 hours after adding Puerariae Radix water extract(32 ㎍/ml) and B(a)P(50 uM). In vivo experiment, Puerariae Radix water extract(0.25 g/kg/day, per os) was administered for 7 days and B(a)P(0.1 mg/kg/day, intraperitoneally) was given after the last administration of extract. And then the hepatoprotective effect of Puerariae Radix water extract was investigated biochemically through in vitro and in vivo experiments. Namely, activities of enzymms (GOT, GPT and LDH) were measured and 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide(MTT) assay were carried out in vitro cell culture study and GOT, GPT, LDH and ALP activities and HDL-cholesterol, total cholesterol and triglyceride contents were performed in vivo study. In vitro experiment, Puerariae Radix water extract stimulated hepatocyte proliferation and significantly recovered enzyme activities (GOT, GPT and LDH) in comparison to group II administered B(a)P. In vivo experiment, Puerariae Radix water extract significantly decreased the enzyme activities(GOT, GPT, ALP and LDH in serum and ALP in tissue) and lipid contents(TC and TG) changed by B(a)P to normal level.
