生絲纖度檢査規定에 關한 考察

최진협,Choi, Jin-Sub 한국잠사학회 1983 한국잠사곤충학회지 Vol.25 No.1

現 生絲檢査規則 中 纖度偏差檢査項目에 관하여 檢討한 結果 약간의 矛盾點을 發見하였으므로 이를 지적하고 그 改善策을 設定하였다. 1. 現 纖度偏差檢査는 平均纖度가 50~69 denier에 標準偏差는 5.80以下, 4.61 以上일 때 A格으로 定하고 있으나 平均纖度 50 denier인 경우의 標準偏差 5.80과 平均纖度 69 denier인 경우의 標準差 5.80과는 同一分布라 할 수 없다. 2. C.V로 換算하여 볼 때 2A格의 C.V가 A格의 C.V보다 작아야 하는데 現 纖度檢査規定은 70denier 의 1A格의 C.V換算値는 9.00이며, 69denier의 A格의 C.V換算値는 8.41로서의 70denier 2A格이 69denier의 A格보다 變異의 分散이 크게 나타나는 矛盾點을 보였다. 3. 生絲의 纖度偏差檢査數値도 平均値가 다른 Sample끼리의 優劣을 나타내는 數値이며 이 數値로서 等級을 決定하기 때문에 標準偏差에 의하여 檢査할 것이 아니라 C. V에 의하여 檢査하여야 한다. 4. 33 denier 以上의 生絲에서 각 等級別로 볼 때 6A格에서 下位格으로 감에 따라 變異폭(變異係數)을 약간씩 크게 하였으나 곳에 따라 一貫性을 잃고 있으며 그리고 同一等級에서 纖度變化에 따른 變異係數數値의 變化도 같은 경향이므로 等級間 및 纖度間의 數値調整을 要한다. 5. 34 denier 以上에서는 標準偏差數 値를 代入하기 때문에 同一等級에서 平均纖度가 굵어짐에 따라 標準偏差數値를 크게 하였으나 C. V로 換算하여 보면 大同小異하므로 纖度變化에 따른 C. V數値를 달리 할 필요가 없다. 6. 以上의 1.2.3.4.5項의 矛盾點을 是正하기 위하여 是正하기 위하여 C.V에 의한 檢査方式을 導入하고 33denier 以上에서 각 纖度間과 각 等級間의 均衡을 바로 잡으며 또 34 denier 以上에서 각 等級間의 間隔을 바로 잡기 위하여 曲線回歸公式을 導入하여 調整할 必要가 있다. 7. 生絲檢査에서 纖度偏差檢査表를 다음과 같이 改正實施함이 보다 妥當하다. The study was carried out to suggest on opinion of the standardization of size deviation in the existing raw silk testing method. 1. The present grade A of size deviation stipulates 4.61 to 5.80 of standard deviation for 50 to 69 denier of mean value, however, the 5.80 standard deviation with the mean values of 50 and 69 denier belong to different distribution. 2. It is reasonable that the variation coefficients of grade 2A should be lower than that of grade A. However, the present testing method shows larger variation in grade 2A than in grade A. This is illustrated 9.00 for 69 denier in grade 2A and 8.41 for 70 denier in grade A. 3. The size deviation value compares the quality of raw silk with different mean value. Therefore, the standard deviation is recommended to be replaced by the C.V. value in determining the grade of silk. 4. The C.V. have a tendency to increase with lower grades below 6A for the size deviation below 33 denier with some inconsistencies. The figures should be adjusted so that the C.V. inconsistencies size deviation below 33 denier will be corrected. 5. The standard deviation increases with size under the same grade for the size deviations above 33 denier, however, the C.V. does not vary greatly with size deviation. 6. To rectify the above-mentioned inconsistencies the C.V. conversion and curvilinear regresion correction is recommended to improve the present silk testing method 7. The table of size deviation standard are as follows: Suggested standard of size deviation, unit: C.V. Value

대기공해가 잠아의 실용형질에 미치는 영향을 알고자 일본종계통 2품종과 중국종계통 2품종을 오염상 비오염상세, 척상별로 사육하고, 또 상엽 및 잠체중의 S, Cd함량을 분석한 결과는 다음과 같다. 1. 잠아경과일수는 일본종계통은 비오염구에 비해 오염구가 2.5일 정도 중국종계통은 4일정도 지연 및 불재일하였고 세척구는 중간 정도였다. 2. 잠아 5령극대체중, 견층중, 전견중 등은 비오염구, 세척구, 오염구 순으로 성적이 떨어졌다. 3. 화용비율은 상엽처리별로 볼 때 일본종은 유의성이 없었으나 중국종은 고도의 유의성을 나타냈다. 4. 오염상엽에 대한 저항성은 일본종계통에 비하여 중국종계통이 현저하게 약하며 동일계통에서도 종간에 차가 있다. 5. 오염지역의 상엽은 비오염지역의 상엽보다 S 및 Cd의 함량이 각각 약 30%, 300%증가하였다. 6. 잠체내에서도 비오염상 급여구는 S가 0.41%, Cd 0.013ppm이고 세척상 급여구는 S가 0.52%, Cd가 0.042ppm순으로 높았다. 7. S 및 Cd의 함량이 상엽에 가시적인 피해는 나타내지 않았으나 잠아에는 피해가 심했다. 8. 잠아의 실용형질은 공해로 인한 상엽질의 악화에서 입는 피해보다 상엽에 부착된 분전의 해가 더 컸다. 9. 이상을 종합해 보면 분장지대 선정에 있어서 중국종계통은 공해지역을 피할 것이며 부득이한 경우는 상엽을 세척급여하면 현저한 효과를 거둘 수 있을 것이다. Those studies were examined rearing two varieties on Japanese descent and two varieties of Chinese descent by feeding polluted mulberry leaves, non-polluted ones and water-cleaned ones respectively to find effects of air-pollution on the economic characters of silkworms and analysis of contents of Sulphur and Cadmium in the mulberry leaves and silkworms as followings; 1) Japanese descent of polluted part was delayed about 2.5 days than non-polluted part, Chinese descent was delayed about 4 days or inequal and water-cleaned part was medium in the silkworm larval duration. 2) Results of maximum weight of 5th instar, cocoon layer weight and cocoon weight were decreased in due order non-polluted, water-cleaned and polluted in the factors of mulberry. 3) Pupal ratio of Japanese descent was not shown statistical significance, but Chinese descent was revealed it obviously in the factors of mulberry leaves. 4) In the resistance of polluted mulberry leaves, Chinese descent was feeble obviously than Japanese and there were some difference even through among the same varieties. 5) The content of S and Cd of polluted area mulberry leaves was increased about 30% respectively than non-polluted area. 6) The fed part of non-polluted mulberry leaves was S 0.41% and Cd 0.013 ppm water-cleaned part was S 0.47% and Cd 0.024 ppm and polluted part was S 0.52% and Cd 0.042 ppm in the contents of S and Cd of silkworm larvae. 7) The contents of S and Cd didn`t make visible injury in mulberry leaves but made it seriously in silkworm larvae. 8) The injury of dust on mulberry leaves was more serious than that of quality of mulberry leaves by air-pollution in the economic characters of silkworm. 9) As above results, Chinese descent should avoid contaminated area and it rearing by water-cleaned mulberry leaves can get noticable results in inevitable case on selection of parents silkworm rearingzone.

大氣公害가 養蠶에 미치는 影響에 관한 硏究 : 人工 飼料中의 카드미움 濃度와 家蠶形質과의 關係 Relation between Silkworm larval characters and the levels of cadmium density in diets

李鍾哲,崔震浹,裵啓宣,孫興大,鄭元福 東亞大學校 大學院 1980 大學院論文集 Vol.4 No.2

Performed to study on effect of economic characters and quantity of Cd in silkworm body by feeding artificial diet which aded Cd per density to all age silkworms. The results were as follows: 1. Each treated parts was a little longer than control on silkworm larval duration. 2. Growing condition of 40 ppm on the 7th day after commencement incubation was uneven and found out around 80% of 1st instar-silkworm larvae which almost didn't grow at ones of 80 ppm. 3. Maximum weight of the 5th instar, pupation ratio, weight of cocoon, weight of cocoon layer and cocoon layer ratio of parts of 1,10, and 20 ppm was a lettle higher than control, but only ones of 40 ppm was lower than those. And found out it ws chronic toxicity. 4. Each treated parts on eclosion period was longer than control. Expecially non-eclosion ratio of 40 ppm was 30%. 5. The safe level density of Cd in diet was 20 ppm. 6. Toxicity will be occurred when Cd contents in is more than 5 PPM in silkworm body.

裵啓宣,崔震浹,孫賢秀 東亞大學校 大學院 1984 大學院論文集 Vol.8 No.2

The study was carried out to examine effect of cadmium and zinc on the growth of Chlorella. The results obtained were as follows. 1. The chlorella cells damaged by heavy metals showed yellowish to milk-white symptoms at initial stage and died at later stage. 2. The cadmium has more inhibitory effect than on the turbidity cell number, chlorophyll contents and protein contents. 3. The chlorella cells were damaged more remarkably by the higher concentration of cadmium and zinc. 4. In conclusion, the minimum concentration of heavy metals to effect on the growth rate of chlorella cells were 2 ppm cadmium and 30 ppm of zinc.

房極勝,崔震浹,金正基 東亞大學校 大學院 1984 大學院論文集 Vol.8 No.2

A single and rapid method for quantative determination of immunoglobulin in serum is described. The method uses polyethyleneglycol which causes precipitation of immunoglobulin and investigation into electrophorectic pattern of serum by polyethyleneglycol and correlation between total protein concentration and immunoglobulin concentration have been performed. The polyethyleneglycol precipitation test described provides a rapid, accurate and precise way to measure immunoglobulin.
