        치과기공사들의 호흡기 자각증상 및 관련요인

        정희선,이무식,김남송 대한보건협회 2002 대한보건연구 Vol.28 No.2

        본 연구는 치과기공사들의 호흡기 및 근골격계 자각증상에 관한 호소율과 관련요인을 조사 분석하여 직업성 질병을 예방하고 효율적인 건강관리와 작업 환경 개선을 위한 기초자료를 제공하고자 실시하였다. 연구대상을 전국의 치과기공소(실)에 근무하고있는 치과기공사를 무작위로 추출하여 우편 설문조사에 응답한 265명 이었으며 조사기간은 2000년 12월부터 2001년 3월 까지였다. 수집된 자료는 Spss 8.0프로그램을 사용하여 X2-test와 로지스틱 회기분석을 통하여 다음과 같은 결론을 얻었다. 조사대상자의 성별에 따른 일반적 특성을 분석한 결과 연령, 결혼상태, 흡연여부, 음주여부와 유의성이 있었고 직무특성 분포에서는 치과기공경력, 담당업무, 직위에 따라 유의성이 있었다. 호흡기 장애 호소율을 분석한 결과 평소시침 호소율(55.5%)이 가장 높게 나타났고 다음은 담.가래(52.5%), 숨참.숨헐떡임(42.6%), 콧물.코감기(39.2%), 숨쉴 때 소리(23.4%)순이었다. 로지스틱 회귀분석에서 평소기침 호소율에 유의한 영향을 준 요인으로는 직위였고, 담.가래는 직장소재지였으며, 콧물.코감기는 성별, 연령, 결혼상태, 직위였다. 이상의 결과로 볼 때 치과기공사들의 신체 자각증상 호소율은 비교적 ?? 나타났으며 효율적인 건강 관리와 작업환경 개선을 위해 치과기공과 재학생들에게도 치과기공 재료들의 유해성에 대한 보건관리 교육 실시 및 재료등의 유해성 방지를 위한 전문 연국기관이 요구되며 치과기공사들의 적극적 자기관리와 치과기공소 운영자의 정기적인 작업환경 측정으로 쾌적한 환경유지가 필요하다. 또한 치과기공사들의 직업적 특성을 고려한 건강관리 교육 및 전용의료기관을 지정하고, 정기 건강검진을 실시하여 질병 예방의 제도적 장치가 필요할 것으로 판단된다. The purpose of this study was to serve as a basis for the protection of dental technicians from occupational diseases, more successful health care for them, and the betterment of working environment, by examining their complaints about respiratory subjective symptom and the relevant factors. The study subjects were 265 dental technicians who were randomly selected from dental technology shops nationwide and respondent to a mail survey. The survey was conducted from December 2000 to March 2001. The collected data were analyzed with SPSS 8.0 program, and X^2-test and logistic regression analysis procedures were utilized. Dental technicians suffered coughing in ordinary time(55.5%), phlegm and sputum(52.5%%), shortness of breath(42.6%), nasal discomfort(39.2%). Major predictors to suffer coughing in ordinary time on multiple logistic regression analysis were position in the office, phlegm and sputum were location of work area and nasal discomfort were sex, age, marital status and position in the office. The above-mentioned findings showed that the dental technicians suffered highly from physical subjective symptoms of respiratory system. S0 there are some suggestions about mere efficient health care and better working environment: dental technology students should receive healthcare education to leam the harmfulness of dental technology materials, and a specialized research institution is needed to make a deep study of addressing the harmfulness of the materials. Dental technicians have to pay more attention to their own health care, and dental technology manager should check out working environment on a regular basis to maintain a comfortable environment. In addition, healthcare education should be provided to dental technicians in consideration of their vocational characteristics, and specific medical institutions for dental technicians should be designated. And a regular health examination should be conducted to prevent any possible occupational diseaede.

      • 고성능감수제 구성비율에 따른 고유동콘크리트의 유동특성에 관한 실험적 연구

        김무한,최세진,김용로,김재환,이태희 忠南大學校 産業技術硏究所 2002 산업기술연구논문집 Vol.17 No.2

        It is the of this study to propose the fundamental data for the establishment of the application and quality standard of the mixed type superplasticizer after investigating and comparing the fluidity of high flowing concrete according to the component ratio of superplasticizer such as naphthalene sulfonated and melamine sulfonated. The results of this study were shown as the followings: 1) The fluidity and adsorption ratio of cement-paste were improved according to the increasing of naphthalene sulfonated component ratio, and apparent viscosity of cement-paste was improved according to the increasing of melamine sulfonated component ratio. 2) In case of using the granulated blast-furnace slag, the fluidity of cement-paste was considerably good and the adsorption ratio was decreased and in case of using fly-ash, the apparent viscosity and adsorption ratio of cement-paste were improved. 3) The dispersive capacity performance of concrete can be improved by means of the increasing of naphthalene sulfonated component ratio. Also the viscosity and early strength can be improved by means of the increasing of melamine sulfonated component ratio.

        A 3-year old, male Jindo dog was referred with history of tenesmus, dyschezia and recurrent rectal prolapse. On the physical examination, the rectum was prolapsed about 10 cm, congested and necrotized. Fecal incontinence and pain were observed. Complete blood count revealed a mild leukocytosis and there were no remarkable abnormalities in serum biochemistry profiles. It was diagnosed as a rectal prolapse. Rectal resection and anastomosis was performed for necrotic tissue removal. On postoperative fecal smear, protothecosis was observed. Amphotericin B was administered. There has been no evidence of recurrence of rectal prolapse for ten months.

      • 水分蒸發이 시멘트 모르타르의 휨强度에 미치는 影響

        吳武泳,金駿熙 충북대학교 농업과학기술연구소 1989 農業科學硏究 Vol.7 No.2

        This study was carried out in order to research executed strength loss of concrete in the terms of dryness weather, water evaporation action was affect the bending strength of cement mortar after casting. The mix property of cement-fine aggreagte was 1 : 1, 1 : 3, 1 : 5. And the terms of curing was compared standard curing with direct dryness curing after casting. And 3days,7days,14days strength of mortar was examined. The results obtained fl·on this study are summarized as follows. ① Bending strength of standard curing mortar and direct dryness curing mortar were all together decreased by increasing the mix property of cement-fine aggregate. ② When the period of curing was increasing, bending strength of standard curing mortar was inc-reased without relation at mix property of cement-fine aggregate. But direct dryness curing mo-rtar was decreased. ③ Strength difference between standard curing mortar and direct dryness curing mortar was exte-nsioned by increasing the period of curing. ④ Strength difference between standard curing mortar and direct dryness curing motar was exten-sioned by increasing the mixing volume of cement. ⑤ We must take some measure to cope with water evaporation control by increasing the cement volume in the process of curing the terms of dryness weather.
