To evaluate the prevalence of cumulative trauma disorders in relation to ergonomic evaluation of their work, 260 female directory assistance operators employed in three branch facilities of the nation-wide telecommunication company. Ergonomic evaluation of the work status was done by two industrial hygienists through inspection. Workers were surveyed with standardized self-administered questionnaire and examined by family physicians and an orthopaedician for cumulative trauma disorders. Laboratory examination of serum aspartate aminotransferase(AST), creatinine phosphokinase(CPK), aldolase and rheumatoid factor was done and X-ray of cervical spine and both shoulders was taken from all subjects and nerve conduction velocity test was done on 57 subjects with suspected nerve entrapment cases. Cumulative trauma disorders were categorized into 3 category according to work-relatedness of the disorders. On ergonomic evaluation of the working posture and work environment, improvement of work posture revealed inappropriate postures and devices. Mean age of the subjects were 39 years old and more than 80% graduated high school or above. Ninety-eight percent of the workers employed in the company for more than 15 years and 74.6% of the workers worked at the VDT job for more than 4 years. Mean daily work hours was 8.0 hours per day and mean break hours was 90.5 minutes per day with mean extra work hours of 10.7 hours per month. Mean daily calls were 1128.6 calls in maximum and 864-8 calls in minimum. On laboratory examination, 13.(5.0%) workers had abnormal AST, 53(20.4%) had abnormal CPK, and 1(0.4%) had abnormal aldolase level. On x-ray examination of cervical spine, 111(42.7%) had loss of or reversed normal cervical lordosis, 10(3.8%) had narrowing of intervertebral space. Nerve conduction velocity test was abnormal in 11(19.2%) among 57 workers. Among disorders categorized as work-related, 131(50.4%) were diagnosed to have fatigue myalgia of levator scapulae, 108(41.5%) had cervical strain or sprain, 47(18.1%) had fatigue arthralgia of phalangeal joints, and 47(18.1%) had probable carpal tunnel syndrome, in 10(3.8%) of those diagnosis was confirmed electrophysiologically. Age, seniority, work duration at present job, workload nor location of facilities were associated with the prevalence of symptoms nor specific diagnoses on simple statistical analysis and multiple logistic regression, which seems to be due to highly selected and homogeneous characteristics of the study subjects. Above results shows that cumulative trauma disorders are very prevalent among directory assistance operators and elaborate effort is needed to reduce the cumulative trauma disorders among the operators.

The input voltage of Single-sided linear induction motors (SLIMs) is involved with the time harmonics because most LIM is driven by inverter. Therefore the equivalent circuit for an inverter-fed SLIM has t o be modifided to represent every harmonic present in supply voltage. This paper describes that the dynamic characteristic can be used effectively for analyzing the characteristics of a single-sided linear induction motor using vector driver for PI controller.

인간 존엄성과 인권을 근거 짓는 작업에서의 문제들

김용해 사회와 철학 연구회 2003 사회와 철학 Vol.0 No.6

인간 존엄성과 인권이 인류의 보편적 가치로 인정받아가고 있는 가운데 인간 존엄성의 근거가 무엇인가에 대한 논의는 주로 서구 중심적으로 이루어졌다. 인간 존엄성의 근거에 대한 현대 서구의 논변들, 즉 실체주의, 스패만의 초월적 인격주의, 싱어의 실용주의, 해프너의 존재론적 관념주의, 루만의 기능주의, 몰트만의 신 모상설 들은 결국 서구 철학사에서 반복되어 나타나는 경험론, 실체주의 그리고 그리스도교 신학적 입장에서 더 나아가지 않았다. 세계화의 시대에 다양한 문화가 서로 만나는 상황에서 인간 존엄성의 근거 지음이 정당성을 확보하려면 그것은 문화 간의 대화를 통해 이루어져야 한다. 인간 존엄성을 근거 짓는다는 것은 합리적이고 따라서 호소력 있는 명제를 만든다는 것을 의미하는데, 이것은 종교 문화 간의 개방적 담론을 통해 계속해서 재구성해나가는 방식을 취해야 한다. 이 개방적 담론에서는 실체적 개념들을 단순 비교해서는 안 되고 신-인간-자연 이라는 관계의 맥락 안에서 인간을 이해하고 존엄성을 근거 지어야 한다. 종교는 전체의 의미 체계에서 기초 코드로 이해되며, 따라서 한 사회 안에서 공동체와 문화들 사이에서 의사소통의 위기가 발생하는 것은 결국 종교의 위기라 할 수 있다. 다원주의 사회의 종교의 위기는, 종교 간의 개방적 담론을 통해 인간의 종교성, 즉 종교적 실존의 현의를 내용적으로 수렴해낸다면. 인간의 존엄성을 보편적으로 근거 짓는 데 중요한 단서가 될 것이다.

야생 노랑제비꽃(Viola orientalis W.Becker)의 형태적 특성 및 Callus유도에 관하여

정용모,서정해,조만현,권오창 東亞大學校生命資源科學大學附設 農業資原硏究所 1996 農業生命資援硏究 Vol.5 No.1

부산근교의 고산 지대에 자생하는 야생 노랑제비꽃(Viola orientalis W. Becker)의 외부 형태적 특성과 줄기 조직으로부터 callus형성에 미치는 식물 생장조절제의 영양에 관한 실험을 실시하였던 바 그 결과를 요약하면 다음과 같다. 잎은 근생엽과 줄기상의 잎으로 구별할 수 있었으며, 엽장, 엽폭, 그리고 엽면적 각각 3.9㎝, 4.7㎝ and 15㎠로 모두 근생엽이 skjawl 줄기상의 잎보다 컸다. 그러나 엽형지수에 있어서는 근생엽이 0.83으로 가장 작았고 줄기상의 가장 작은 잎이 1.30으로 제일 크게 나타났다. 식물 생장조절물질의 단용에서 callus 유도는 Auxin의 NAA5×10??, 5×10??, 5×10??M에서 양호하였다. Auxin과 Cytokinin의 혼용에서 callus유도는 NAA 5×10??M 및 5×10??M에 BA 5×10??, 5×10??, 5×10??M의 전구에서 양호하였다. Callus 성장이 가장 양호한 조합은 NAA 5×10??M + BA 5×10??M 및 NAA 5×10??M + BA 5×10??M이었다. This experiment was conducted to study morphological feature and effect of plant growth regulators on callus induction of wild viola(Viola orientalis W. Becker). The results obtained were summarized as follows: In morphological feature, there was two distinctive leaf-forming types : one was rosette type derived from subterranean stem and the other was leaves formed on stem. Generally rosette type leaves were larger than others and the leaf length, leaf width, and leaf area were 3.9㎝, 4.7㎝ and 15㎠ on average, respectively. In the leaf shape index(the ratio of leaf length/width), the smallest value(0.83) was shown on rosette leaf while the greatest value(1.30) was determined from leaves on stems. Callus induction from the stem segments of wild viola was relatively higher at NAA concentrations of 5x10??M, 5x10??M or 5x10??M than at the same ones of other regulators used. The most effective combined concentrations of Auxin and Cytokinin for the callus formation were 5×10??M of NAA plus 5×10??M of BA or 5×10??M of NAA plus 5×10??M of BA.

韓海龍,張田益,朴庸奉 제주대학교 1981 논문집 Vol.13 No.-

양하는 생강과 더불어 중요한 香辛菜蔬지만 濟州道에서는 그 栽培法과 양하의 食用價値를 정확히 모르고 있다. 이에 繁殖方法의 하나로서 遮光程度를 달리하였을 경우 양하의 生育과 收量 및 無機物 含量에 미치는 影響을 調査한 結果는 다음과 같다. 1) 양하의 草長과 葉數는 遮光程度가 높을수록 增加하는 傾向을 보였으나 葉소莖과 葉幅은 生育初期에는 處理間에 비슷한 傾向을 보였으나 生育後期에는 增加하는 速度가 緩慢하였고 遮光程度가 낮을수록 增加하였다. 2) 3.3㎡當 收量은 70%遮光區에서 가장 많았고 處理區는 對照區 보다 多少 增加하는 傾向을 보였다. 3) 줄기와 잎에서는 遮光程道가 높을수록 窒素, 인산, 가리, 마그네슘, 망간의 含量이 對照區 보다 增加하였으나 鐵成分 만은 對照區의 줄기에서 가장 많은 含量을 보였다. 4) 위의 實驗의 結果 양하의 生育, 收量 및 無機成分量은 70%遮光에서 增加하였고 앞으로 遮光程度와 處理時期을 달리하여 계속 硏究할 必要가 있다고 생각된다. Among major condimental vegetables, Zingiber mioga and ginger has not yet been examined in cultivation method and contents of inorganic element in Cheju Island. This experiment therefore was carried out to investigate the effect of several shading treatments on growth, yields and contents of inorganic elements of Z. mioga. The results are as follows : 1) The higher the shading degree, the higher the plant height and leaf number, but neck diameter and leaf width showed no significant difference from the early growth period while the late growth period, the lower the shading degree, the higher the neck diameter and leaf width. 2) In the yields of 3.3㎡ unit area, the 70% shading treatment showed sligh increase in compare with other treatment. 3) In contents of the inogranic element of leaf and stem, the higher the shading degree, the higher the content of nitrogen, phosphor, potassium, magnesium and manganese, but only the iron increased in compare with other treatment at the stem of control lot. 4) The result indicated that the growth, yields and contents of inorganic element increased significantily at the 70% shading treatment. The results also point out that study of different shading degree and shading period are necssary.

이용욱,김성민,구태완,이혜린,강일호,한길로,이혜승,황적준 大韓法醫學會 1999 대한법의학회지 Vol.23 No.1

The hypervariable short tandem repeat(STR) locus D12S391 was investigated in a Korean population. A total of 14 alleles were detected by size under denaturing conditions in 517 unrelated individuals. To confirm all of the alleles detected in a Korean population, a total of 34 fragments were sequenced. Prior to allele designation, we constructed the allelic ladders containing 11 alleles sequenced in this study. Allele 18 is the most common with a frequency of 0.281 in Koreans, and one variant allele 19.3 which have been confirmed by sequencing, was detected. The observed heterozygosity, the power of discrimination (PD), and the mean exclusion chance (MEC) for the locus D12S392 is 0.781, 0.946 and 0.652 , respectively. No deviation from Hardy-Weinberg equilibrium was observed in a Korean population (p=0.557). In the 424 meioses in 105 Korean families confirmed using other 17 STR loci, no mutation was detected in locus D12S391. The STR locus D12S391system is useful both for the analysis identification and parternity.

The purpose of this study was to investigate the differences in the perception of housing unit between female and male among high school students who have learned Home Economics in high school. The number of 200 samples were analyzed with frequencies, percentages, t-tests, regressions and x? analyses using SPSS/Win. The results showed that there were no sexual differences in general perceptions of Housing unit such as importance, usefulness, and satisfaction with the unit. The most demanded housing contents as the principle of interior design, and the least as the history of housing. There were sexual differences in only a few contents. However, all of 29 items were demanded over median point of 3.0. Most students often imagened their own dream houses and thought about the way to improve their own rooms. They were least concentrated on the newspaper articles on housing. They were sexual differences in the level of practice the Housing contents learned in the class. These results should be considered in the 7th curriculum male students must take Home Economics.
