대구시 및 경북 일부지역(1개시와 8개군)중 18개 업종 722개 사업장을 대상으로 작업환경의 관리자료로 활용하기 위하여 1986년 2월 1일부터 1986년 12월 30일까지 작업환경조사를 실시하여 다음과 같은 결과를 얻었다. 1. 생산직 근로자 83,368명 중 유해인자에 폭로된자는 37,697(45.2%)이었다. 2. 소음은 전체적으로는 약 59%가 기준을 초과하였으며 조리금속 제조업의 제정부서와 섬유제품 제조업의 직포기 부서가 각각 100.5dB(A), 100.1dB(A)이었다. 3. 분진은 약 6%가 기준을 초과하였으며 석탄제품 제조업이 분쇄기가 5.3mg/m³이었다. 4. 조명은 약 44%가 기준에 미달하였으며 음식료품 제포업의 저장기 20-70Lux, 섬유제품 제조업의 권(단)사 50-70 Lux, 나무 및 나무제품 제조업의 도장기 40-70 Lux, 석탄제품 제조업의 배합반 등이 20-70 Lux로 불량하였다. 5. 온열지수는 약 12%가 기준을 초과하였으며, 1차 금속제품 제조업의 압연기 37.9℃, 환원실 34.7℃로 허용기준치를 모두 초과하였다. 6. 유기용제의 약 8%가 기준을 초과하였으며 개별적 초과율은 다음과 같다. 1) 톨루엔 : 조립금속제품 제조업의 접착작업시 105 ppm 2) 크실렌 : 화학제품 제조업의 페인트 배합기 및 인쇄기에서 150-215 ppm 3) 메칠 에칠 케톤 : 화학제품 제조업의 페인트 배합기에서 205 ppm 4) 메칠 이소부칠 케톤 : 화학제품 제조업의 인쇄기에서 320 ppm 5) 아세톤 : 조립금속 제조업의 증기광택 작업시 897 ppm 6) 혼합물질의 허용농도를 초과하는 곳은 화학제품 제조업의 크실렌, 메칠 에칠 케톤, 메칠 이소부칠 케톤 등 이었다. 7. 특정화학물질은 약 0.8%가 기준을 초과하였으며 염화수소는 조립금속 제조업의 산처리 작업시 최고 6ppm으로 3개사 중 1개사가 허용기준치를 초과하였으며, 그의 물질들인 벤젠, 빙초산, 개미산, 가성소다, 포르말린, 암모니아, 동, 텅스텐, 비스무트, 몰리브덴, 망간, 카드뮴, 비소, 아연, 크롬(산) 등은 모두가 허용기준치 미만이었다. 8. 연은 1차 금속제품 제조업의 용해로, 통신업의 맨홀, 인쇄 및 출판업의 주조 및 연판기 등에서 0.0025 mg/m³- 0.101mg/m³으로 허용기준치 미만이었다. 이상의 결과로 보아 아직까지 작업환경 관리는 만족하다고 할 수 없으며 보다 더 철저한 관리가 필요하다고 하겠다. Examination of working environments was conducted to get more detailed data about harmful working environments and to make a contribution to more effective management. Study was carried out on 722 factories located in Taegu City and eight counties in Kyungpook Province, Korea, for a period of one year, from February 1 to December 30, 1986. The total number and proportion of workers exposed to harmful material was 37.697, 45.2% among 83,368 workers. The results according to exposed material were as follows : 1. In the case of noise, proportion of exceeding the 8-hour TLV was 59%. Included were nail-cutting in assembly metal manufacturing industry and weaving process in textile. 2. Dust in mill process of coal manufacturing industries exceeded the TLV of second class of dust at all parts and exceeded the TLV at 6% as a whole. 3. The fields of industry lower than 70 kux of illumination were storage equipment of food, auto-winder of textile, painting of wood wares and coal mixing, and 44% of all cases was lower than standard. 4. As a result of temperature index investigation(WBGT), about 12% of all sujects exceeded limit value. Included parts were rolling machine and reducing room. 5. In the case of organic solvents, TLV was exceeded at about 8%. The parts exceeded TLV according to materials belonged to this category were as follows. 1) Toluene : adhesive work in assembly metal manufacturing 2) Xylene : printing and paint mixing in chemical manufacturing 3) Methyl ethyl ketone : paint mixing in all parts examined and coating machine partially in chemical manufacturing 4) Methyl isobutyl ketone : printing in chemical manufacturing 5) Acetone : vapor polishing in assembly manufacturing. 6. Among specified chemical materials, the concentration of HCl in the air in metal assembly manufacturing factory exceedeed TLV in one of three assembly metal manufacturing examind. Others, such as benzene, acetic acid, formic acid, sodium hydroxide, formalin, ammonia, copper, chromate etc. were lower than TLV in its indoor atmospheric concentration. As a whole, the proportion of exceeding TLV was about 0.8%. 7. The concentrations of inorganic lead were lower than TLV in all parts examined. The results of this investigation show the fact that current management of working environments is not satisfactory, and so more active management is needed.

허리 근육손상은 기대치 못한 상황에서 신체의 적절한 반응이 지연될 경우 근육 염좌와 같은 상해나 요통으로 연결된다. 이 연구는 척추 안정 운동 후 척추의 유연성과 척추 근육의 반응 속도를 만성 요통 환자와 정상인을 대상으로 비교 연구 하였다. 만성 요통 환자 군은 척추 안정 운동을 4주간 20회 시행하였으며 이와 비슷한 특성을 가진 대조군을 비교하였다. 신체 유연성은 환자가 앉은 자세에서 척추를 축으로 신체의 회전 정도를 측정하였다. 척추 반응 속도 측정은 환자가 선 자세에서 두 손으로 판을 들고있는 동안 정구공이 1.8m (6.4N) 에서 낙하시 좌, 우측 척추 근육의 반응 속도를 Wavelet 분석으로 측정하였다. 연구 결과 척추 안정 운동을 행한 만성 요통 환자군의 신체 유연성과 척추 근육 반응 속도가 통계적으로 유의하게 증가하였다. 척추 유연성은 만성 요통 환자 군에서 131.0cm에서 척추안정 운동후 144.1cm으로 증가하였다(p〈0.05). 척추 근육 반응 속도는 척추 안정 운동을 행한 만성 요통 환자 군에서 90.00msec에서 68.55msec로 (p〈0.05), 정상 군에서는 86.28msec에서 75.64msec로 (p〉0.05) 단축되었다. 척추 안정 운동은 근, 신경 조직의 반응속도를 증가시키며 특히 만성 요통 환자에서 척추의 안정성을 회복시킨다. 특히 척추의 안정성 증가는 기대치 못한 상황에서 신체의 적절한 반응의 속도를 회복시키며 결과적으로 허리 손상을 예방할 수 있다. 물리치료학에서 근 골격 신경계의 반응 속도측정을 위한 연구로 Wavelet 분석과 같은 첨단장비를 통한 운동 치료의 질에 관한 연구의 도입이 필요하다. 또한 구체적인 치료적 운동결과의 측정을 통해 물리 치료의 효과성과 효율성을 높이기 위한 생체의학적 연구가 요망된다.

This experiment was carried out to investigate the correlation of accuracy among five kinds of instruments which determined an airborne dust at the various locations of same type work. The results obtained were as follows; 1. Digital dust indicator-P type (DDI-P) instrument for determination of relative concentration was found not having significant variations when it was used without corrective coefficient to the quantitative concentration at the places with a few airborne dust in office and laboratory room. 2. Generally, there were the high correlations between determination values resulted by Digital dust indicator(DDI) and Piezobalance(PB). However, the correlation of two instruments to a filter weighing method was insignificant in the same type work. After determining several times (at least 5 times and over), it was desirable to fix the corrective-coefficient. 3. When the size of the particles of airborne dust was large or its concentration was high in suspended airborne dust, the determination values of High volume air sampler-Respirable(HVS(R)) were 2-4 times higher than that of Low volume air sampler-Respirable(LVS(R)). 4. The emyloyment of corrective coefficient for determination values of DDI and PB was not appropriate to HVS(R) comparing with LVS(R) because of the significant changeable differences. In addition, the determination instruments for relative concentration was not appropriate to using by itself at a manufactruing process. There were also problems about sampling time and evaluation when it was determined the total airborne dust with the open face type holder.
