金公朱,姜濚義 全北大學校 1979 論文集 Vol.21 No.-

This paper concerns with the utilization of the treatment of sulfuric acid for improvement of dyeing of poly ethylene terephthalate(P. E. T) fiber. The P. E. T. fiber drafted to various times was treated with 70~74% sulfuric acid at 80~95℃ for 30~120min and neutralized with 2% ammonia. The fiber thus prepared has remarkable advantage in high yields of colours when dyed with C. I. Basic Green 4. The tensile strength of 3.2 times drafted P. E. T. fiber is as high as that of used fiber.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

The purpose of this study is to evaluate the use value of tooth ash-plaster mixture as an alternative material of the synthetic hydroxyapatite. For this purpose the author performed the experimental study to investigate the physical properties of sintered tooth ash-plaster mixture. The tooth ash was made by increasing procedure at 850℃, 900℃ and 950℃ for 20min, 40min and 60min respectively. The composition of tooth ash was analyzed using ICPSE and X-ray diffraction was done. The experimental specimens were molded to the cylindrical from 10mm high, 5mm diameter under the pressure of 1,000kg/㎠ for test of compressive strength values and 3mm high, 6mm diameter for test of diametral tensile strength values and surface microhardness values. Mixtures of tooth ash-plaster mixture was vacuum fired at 1,000℃ for 60min. The physical properties of the sintered specimen were examined and their microstructures were observed under the scanning electron microscope. The results were as follows: 1. x-ray diffraction showed the crystallization of tooth ash was developed as the incinerating temperature and time were increased, but the phase transformation following the incinerating temperature and time was not occurred. 2. The values of compressive strength of the sintered tooth ash-plaster mixture were the highest in case of incinerating temperature 950℃, the incinerating time 60min, and the tooth ash-plaster mixing weight ratio of 4:1. The higher tge incineration temperature and the longer the incineration time was, the more increased the compressive strengths were(p<0.01). 3. The values of diametral tensile strength of the sintered tooth ash-plaster mixture were the highest in case of the incinerating temperature 950℃, the incinerating time 60min, and the tooth ash-plaster mixing weight ratio of 4:1. The higher incineration temperature and the longer the incineration time was, the more increased the diametral tensile strengths were (p<0.01). The more decreased tooth ash-plaster mixing ratio was, the more increased the diametral tensile strength was, but there was not a significant difference statistically (p<0.01). 4. The values of surface microhardness of the sintered tooth ash-plaster mixture were also the highest in case of the incinerating temperature 950℃, the incinerating time 60min, and the tooth ash-plaster mixing weight ratio of 4:1. The higher the incineration temperature was, the more increased the surface microhardness values were, but there was not a significant difference statistically(p<0.01). The longer the incineration time was and the more decreased the tooth ash-plaster mixing ratio was, the more increased the surface microhardness values were. 5. The porosity and absorption of the sintered tooth ash-plaster mixture were the highest in case of the incinerating temperature 850℃, the incinerating time 20min, and the tooth ash-plaster mixing weight ratio of 3:1. The lower the incineration temperature was and the shorter the incineration time was, the more increased the porosity was. 6. There was a good wettability in the sintered tooth ash-plaster mixture under the scanning electron microscope.

Chrysanthemum boreale (C. boreale) has been used for the treatment of furuncles, carbuncles, sores, conjunctivitis, headache, vertigo and swollen throats as a folk medicine in Korea, but there is little report about experiment evidence of antimicrobial activity. To investigate the antifungal and antibacterial activity of Chrysanthemum boreale(C. boreale) volatile substance and EDTA, the growth inhibition against Aspergillus nidulans (A. nidulans), Fusarium oxysporum (F. oxysporum), Alternaria mali(Al. mali), Candida albicans (C. albicans), staphylococcus aureus (S. aureus), Streptococcus pyogenes(S. pyogenes), streptococcus mutans (S. mutans), Escherichia coli(E. coli), Helicobacter pylori (H. pylori) and Porphyromonas gingivalis (P. gingivalis) was monitored by agar dilution and broth microdilution method. The antifungal effect of C. boreale on A. nidulans, F. oxysporum, Al. mali and C. albicans was shown at the concentration of 0.04%. The antibaterial effect of C. boreale on S. aureus, S. pyogenes, S. mutans and H. pylori was shown at the concentration of 0.04%. However, the growth was inhibited at the concentration of 0.04% irrespective of the presence of EDTA 0.125% was much higher than higher than that of several concentration of volatile substance. The minimum inhibitory concentrations of volatile substance were 0.16% against S. aureus, 0.04% against S. pyogenes, 0.02% against S. mutans, 0.40% against E. coli, and 0.18% against C. albicans. The growth of human gingival fibroblasts was not affected by C. boreale volatile substances at the concentration of 0.04%. These results indicate that volatile substance from C. boreale may have biologically toxic activities to the microorganisms.

Although noise-induced hearing loss (NIHL) is the most prevalent occupational disease in Korea, only 10% of the diagnosed cases are compensated. Old (1989-94) and current diagnostic criteria, criteria for workers' compensation of NIHL in Korea, compensation formulas of American Medical Association/American association of Ophthalmology and Otolaryngology (AMA/AAOO), the Committee on Hearing, Bio-Acoustics, Biomechanics (CHABA), American Academy of Otolaryngology (AAO) recommendation were compared. Each criterion was applied on the audiomety data of 4044 workers (8023 ears), who had received the second line screening test of Special Periodic Health Examination Program for noise-exposed workers during 1991-2. First, the resulting proportions of NIHL cases by employing each criterion were compared and strength of agreement was measured using kappa value. Temporary Threshold Shift (TTS) was corrected by noise free interval, and the reduction ratio of NIHL cases was calculated. Theoretical progression model of NIHL was reconstructed from previous studies on the natural course of NIHL to evaluate the change of diagnosis result of each criterion in the model. The kappa value between old and current criteria was 0.19, 0.55 for current criteria and workers' com. criteria, ranging from 0.08 to 0.78, highest coincidence was observed between current criteria and CHABA formula. The current criteria produce most similar results with CHABA formula. If TTS is corrected for NFI, there is about 14% reduction of NIHL cases. The results of applying on NIHL progression model divided the formulas roughly into 3 groups, of which compensation criteria was the most, old criteria and AAO the least conservative. In conclusion, the result of 4 ㎑ audiometry should be excluded in evaluation of hearing level and a new hearing conservation program should be set out. Current diagnostic criteria has an ambiguity in that managerial concept for prevention and purpose of compensation is mixed up. The current diagnostic criteria and compensation criteria could be incorporated into a new formula which is based on the state of the art test for estimating everyday hearing disability.

To investigate the antimicrobial and antifungal activity of Chrysanthemum boreale(C. boreale) essential oil, the growth inhibition against Aspergillus nidulans, Fusarium oxysporum, Alternaria mali, Staphylococcus aureus, Streotococcus pyogenes, Streptococcus mutans and Escherichia coli in the presence of the essental oil was monitored by agar dilution method. The antifungal effect of C. boreale on Aspergillus nidulans, Fusarium oxysporum and Alternaria mali as affected at the concentration of 400 ppm. The antibacterial effect of C. boreale on staphylococcus aureus, streptococcus pyogenes and Streptococcus mutans was affected at the concentration of 0.4 μl, while growth of E. coli was not inhibited at the concentration of essential oil. The results of this experiment on microorganisms indicated that naturally occuring chemical substances from C. boreale might have biologically toxic activities, that is, allelopathic potentials to the microorganisms.

VDT작업자에서 업무로 인한 정신사회적 스트레스에 대한 인지가 근골격계장애에 미치는 영향

업무에 의한 정신사회적 스트레스가 근골격계 질환의 유병에 미치는 영향을 파악하기 위하여 전화안내원을 대상으로 단면적 조사연구를 수행하였다. 연구 결과 나이, 교육정도, 근무연한, 가사부담 등의 인구학적 변수는 근골격계질환의 유병에 영향을 미치지 않는 것으로 분석되었다. 정신사회적 스트레스 중 업무요구도가 높다고 느끼는 집단에서 그렇지 않은 집단에 비해 근골격계 질환의 유병률이 통계적으로 유의하게 높게 나타났으나 업무재량도나 사회적지지도는 근골격계질환과 유의한 상관관계를 발견할 수 없었다. 그러나 업무요구도는 높고 업무재량도는 낮다고 느끼는 '근무긴장도가 가장 높은 군'은 업무요구도는 낮고 업무재량도는 높다고 느끼는 '근무긴장도가 낮은 군'에 비해 근골격계 질환의 발생위험이 통계적으로 유의하게 높은 것으로 나타났다. 본 연구의 결과는 업무로 인한 정신사회적 스트레스에 대한 인지 정도에 따라 근골격계질환의 유병률이 달라짐을 시사하고 있다. 따라서 작업관련성 근골격계질환의 예방을 위해서는 기존의 인간공학적 접근 이외에 스트레스를 감소시키려는 노력이 동시에 진행되어야 할 것으로 생각한다. A cross-sectional study was conducted to assess the association between perceived occupational psychosocial stress at work and the work-related musculoskeletal disorder(WRMSD) among employees using video display terminals. The study included 111 female telecommunication employees from three companies at ChungBuk province. Cases of WRMSD were defined using symptom questionnaire and physical examination conducted by rehabilitation specialist. Information on demographics, individual factors, and perceived psychosocial stress, were obtained by self-administered questionnaire. For assessing perceived psychosocial stress, we used variables from 'job strain model' proposed by Karasek. Associations between perceived psychosocial stress and WRMSD were assessed by multiple logistic regression models. Forty nine(44% to the total) subjects met our operational definition for WRMSD. Age, seniority, housing load were not associated with WRMSD. Perceived psychosocial stress was associated with WRMSD[odds ratio=3.28, 95% confidence interval: 1.05-10.19]. This study suggests that perceived occupational psychosocial stress is related to the prevalence of WRMSD.
