비디오테이프 제조공장에서 혼합유기용제의 폭로가 청력에 미치는 영향을 보기 위해 톨루엔, 메틸에틸케톤, 메틸이소부틸케톤에 폭로된 근로자 51명과 대조군 57명 총 108명을 대상으로 순음청력기계를 이용하여 기도 및 골도청력검사를 실시하였다. 양군의 평균연령은 폭로군 34.1세 비폭로군 35.8세 였으며 폭로군의 평균 폭로기간은 7.3년이었다. 두 군의 고음청력 손실자율은 폭로군 23.5%, 비폭로군 17.5%로 고음청력분류기준에 따른 청력손실유무와 폭로유무에 대한 통계적으로 유의한 차이는 없었다. 주파수별 청력의 비교에서 기도청력검사상 오른쪽은 8000Hz를 제외하고 250, 500, 1000, 2000, 4000Hz에서 통계적으로 유의하게 나왔고, 왼쪽은 250, 500, 1000Hz에서 통계적으로 유의 한 차이가 있었다. 골도청력검사상 오른쪽 250Hz을 제외하고 왼쪽 250, 양쪽 500, 1000, 2000, 4000Hz에서 통계적으로 유의하게 나왔다. 전체적으로 볼 때 기도 및 골도청력 모두에서 비폭로군에 비해 폭로군에서 평균청력역치가 더 높게 나타났다. This study was performed to evaluate the effects on hearing of video tape manufacturing workers exposed to organic solvents. The experimental groups included solvents exposed group 51 and unexposed group 57 workers. All workers was examined air and bone conduction sensitivity by pure tone audiometer. The mean age of solvents exposed group was 34.1 and nonexposed group was 35.8. The mean duration of solvents exposed group was 7.3years. High frequency hearing loss prevalence of both groups was 23.5% in the group exposed to organic solvents and 17.5% in nonexposed group. There is no statistical significants in the prevalence of high frequency hearing loss. According to comparison of mean auditory threshold value by frequencies, on the air conduction test, right was statistically significant in the 250, 500, 1000, 2000, 4000Hz, except 8000Hz. Left 250, 500, 1000Hz was statistically significant. On the bone conduction test, left 250, both 500, 1000, 2000, 4000Hz, except right 250Hz, was statistically significant difference. Generally, auditory sensitivity threshold of the exposed group was higher than the nonexposed group.

본 실험은 plain yoghurt에 배추즙의 혼합비율을 달리하여 frozen yoghurt mix의 pH, 점도 및 보수력과 frozen yoghurt의 유산균 수, 색차, 물성 및 관능검사 결과를 비교 검토하여 frozen yoghurt 제조를 위한 최적의 배추즙 혼합비율을 알아보기 위해 실시하였다. Frozen yoghurt mix에 사용된 plain yoghurt의 당질과 유기산의 함량을 HPLC로 분석하였던 바 당질은 lactose와 sucrose의 함량이 높은데 반해 galactose와 glucose의 함량은 낮게 나타났고, 유기산은 모든 처리에서 유산과 구연산의 함량이 비교적 높은 경향이었다. Frozen yoghurt mix의 pH, 점도 및 보수력은 배추즙의 첨가수준이 높을 수록 낮게 나타났다. 색차는 저장기간 간에는 큰 차이가 없었으나 배추즙 첨가수준간에는 다소 차이가 있었다. Frozen yoghurt의 hardness는 배추즙의 첨가수준이 증가할수록 높게 나타난 반면 cohesiveness나 elastisity는 낮게 나타났다. Frozen yoghurt의 관능검사 결과는 풍미는 배추즙 5와 10% 첨가구에서 높게 나타났고, 조직 및 외관은 배추즙 첨가구에서 무첨가구에 비해 낮게 나타났으나 차이(p<0.05)가 없었다. This study was conducted to find the feasibility of Chinese cabbage juice for making the frozen yoghurt by analyzing the carbohydrates and organic acids contents, pH, viscosity, water holding capacity and the number of lactobacillus bacteria in the frozen yoghurt mix, and the chromaticity, physiology and sensory evaluation in the frozen yoghurt. In the frozen yoghurt mix, the carbohydrates and organic acids produced in plain yoghurt which are the main sources for the frozen yoghurt showed that the amount of lactose and sucrose was higher than any other carbohydrate sources, whereas the lactic acid and citric acid were trended higher than any other organic acid sources. The pH, viscosity and water holding capacity of frozen yoghurt mix were decreased by adding Chinese cabbage juice. In the frozen yoghurt, the chromaticity showed not so much difference in different frozen storage periods, but differences among the Chinese cabbage juice levels. The reology of frozen yoghurt increased by increasing the Chinese cabbage juice level, whereas cohesiveness and elasticity decreased. In the result of sensory evaluation of frozen yoghurt, the flavor showed high at 5% and 10% level of Chinese cabbage juice, but texture and appearance of the products showed lower than that of the control(p<0.05).

To investigate the relationship of subjective symptoms of organic solvent exposed workers with their exposure level and urinary excretion of hippuric acid, 61 male workers who worked in 5 organic solvent using industries were studied. 89 workers were randomly selected from workers group for detailed health examination who visited hospital and had no exposure history to organic solvent as a control group. Personal air concentrations of organic solvent were checked for all organic solvent workers and urinary concentration of hippuric acid for both exposed and control group were also measured. Subjective symptom questionnaire of 31 organic solvent related item were provided to all workers and filled up by themselves and rechecked by medical doctor. The results obtained were as follows: 1. The overall prevalence rate of symptoms were significantly higher in exposed group than control group with statistical difference of 13 symptoms. 2. The overall prevalence rate of symptoms seemed to be increased by the exposure level of organic solvent. 3. The excretion of hippuric acid was more closely related to the level of toluene exposure than the level of mixed organic solvent exposure. 4. In the analysis of multiple stepwise regression using hippuric acid concentration as dependent variable and the concentration of each organic solvents as independent variables, only toluene had significant relationship with hippuric acid and none of other solvent did not affect on the concentration of hippuric acid. 5. In the analysis of multiple stepwise regression using symptom prevalence as dependent variable and the concentration of each organic solvents as independent variables, toluene had most significant effect to the symptom prevalence and the contribution of other solvents was minimal.

중소영세 섬유업체 근로자들 1,138명을 대상으로 자기기입식 설문조사를 하여 근로자의 보건관리형태에 따른 산업보건에 관한지식, 태도 및 실천의 정도를 비교하고 다음으로는 집단보건관리군 694명만을 대상으로 하여 집단보건관리 기간이 지식, 태도 및 실천에 미치는 영향을 알아보고자 하였다. 1. 보건관리형태에 따라서 산업보건에 관한지식, 태도 몇 실천의 평균점수는 개별보건관리군에서 모두 높았으나 실천의 점수만 통계적으로 유의한 차이를 보였다. 그러나 비교하고자 하는 두 집단간에는 대부분의 일반 특성이 유의한 차이가 있으므로 이를 교정하고자 중회귀분석을 실시하였다. 중회귀분석 결과, 지식에 유의한 영향을 미치는 변수는 연령, 교육 수준, 총 근무기간이었고, 태도에 유의한 영향을 미치는 변수는 연령, 교육수준, 결혼상태였다. 실천에 유의한 영향을 미치는 변수는 성, 연령, 교육수준, 결혼유무, 총 직장근무기간이었다. 연구의 목적인 보건 관리형태별로 비교시는 지식, 태도 및 실천에 미치는 영향은 집단보건관리군의 경우 지식의 평균점수가 조금 높았을 뿐이며, 태도 및 실천의 점수는 낮았다. 그러나 두 가지 보건관리형태에 따른 유의한 차이는 없었다. 2. 집단보건관리군에 국한하여 분석한 결과, 보건관리기간(개월수)은 대상 근로자들의 산업보건에 관한 지식, 태도 및 실천 모두에 유의한 영향을 미친다고 할 수 있다. The first purpose of this study was to compare the mean Knowledge, Attitude & Practice(KAP) scores concerning major occupational health between two types of occupational health management in small & medium-scale textile factories. Sample number was 1,138 workers. In small & medium factories with 300 workers or less, they have two alternatives for occupational health management ; Individual Health Management or Vicarious Health Management. The second purpose was to determine if there was a relationship between duration of Vicarious health management and mean KAP scores for 694 workers from the Vicarious Health Management group. We used self-administered questionnaires for measuring KAP. The results of this study were; 1. There was significant difference concerning all socioeconomic & occupational variables (gender, age, education level, marital status, Blue/White collar, working duration of present factory, working duration of total factories) except for shift. 2. There was no significant difference of mean scores of Knowledge and Attitude between the Individual Health Management Group and the Vicarious Health Management. But, the mean score of Practice was significantly different. 3. According to multiple regression analysis, the mean score of Knowledge significantly increased with age, education level, working duration of all factories increased. The mean score of Attitude significantly increased with age, education level and married. The mean score of Practice significantly increased with age, education level, working duration of all factories, married and men. 4. In conclusion, The type of Health management did not significantly affect the mean KAP scores concerning major occupational Health problems. 5. But, the Duration of Vicarious Health management significantly increased the mean KAP scores.

Two young men were seen with nausea, vomiting, dermatitis, seizure after two-four days of occupational exposure to caprolactam, a nylon fiber precursor. There were no significant results in laboratory test, brain CT, FEG except leukocytosis, hyperglycemia. Caprolactam has been shown to induce convulsive disorder in experimental animal studies and Tuma et al(1981) described that one worker acutely exposed to caprolactam developed generalized tonic-clonic seizure with leukocytosis. The coincidence of typical skin lesion with otherwise unexplained generalized tonic-clonic seizure in those young men strongly suggests that caprolactam was causal agent.
