      • 잠견(蠶繭)과 생사(生絲)에 적외선조사(赤外線照射)가 조사(繰絲) 및 생사(生絲)의 물리적성질(物理的性質)에 미치는 효과(效果)

        남중희 ( Chung Hee Nam ),이인전 ( In Jeon Lee ) 한국잠사학회 1967 한국잠사곤충학회지 Vol.7 No.-

        생견 및 건견에 적외선을 조사하여 조사성적과 생사의 품위를 조사하고 아울러 생사에 직접 조사한 때의 실외 물리적 성질을 조사한 결과는 다음과 같다. 1. 생견에 적외선을 조사한 것은 건견 및 무처리구에 비하여 생사량비율이 높았다. 2. 원료견과 생사에 적외선이 조사되면 생사의 강력(4.5g/d)은 향상되나 신도는 저하되었다. 3. 적외선조사에 의하여 생사는 황변화 하였다. The aim of this treatise was to investigate the effects of ultra-red ray on the ree1ability of the undried and dried cocoons as well as the characteristics of raw silk. The results obtained are as follows: 1. The percentage of raw silk of undried cocoons was higher than that of dried cocoon and control. 2. On irradiation with ultra-red ray, it was found that the strength of raw silk increased to 4.5 g/d, while the elongation of it remarkably decreased. 3. The raw silk irradiated with ultra-red ray appeared to be brown in color.

      • 한국(韓國)에서 재배(栽培)되는 상품종별(桑品種別) 영양가치(營養價値) 분석(分析)

        최병희 ( Byong Hee Choe ),남중희 ( Chung Hee Nam ) 한국잠사학회 1962 한국잠사곤충학회지 Vol.2 No.-

        This treatise is to analyze the chemical components in the mulberry varieties which are cultured in Korea and to estimate the nutritive values for them. Some of these varieties were developed lately in this country just by the general breeding aspect of mulberry leaf producing and silkworm raising experimentation without analysing the nutritive values of them which may be differed by various culturing condition. This work will be helpful for the improvement of mulberry varieties and the correct judgement of them. The varieties used for the analysis are as followings; A. Morus bombycis Koridz species. 1. Ichi-Hei. 2. Shimano-Uchi B. Morus alba L. species. 3. Kairyo-Nezumigaeshi. 4. Suwon-Daeyop. 5. Suwon No. 3. 6. Suwon No. 4. 7. Yongchon-Chuwoo. C. Morus Ihou (Ser.) Koidz species. 8. Ro-Soh. The specimens were eventually taken under the air and soil dry season because of the rain shortage during the sampling period and the results are found as a rather different from the normal specimen under the normal climate. Therefore, this treatise will be an important report on a special culturing condition and the nutritive values by the mulberry varieties, and still comparable because they were grown under the same condition. The individual conclusions are; 1. Yongchon-Chuwoo which was originated in this country, was found as an important variety for this country from the aspect of mulberry nutritive value and leaf producing amount, and it is believed that this is the best suitable variety for the soil of Korea. 2. Ichi-Hei occupies the better situation as well as Yongchon-Chuwoo from the nutritive criticizing even though it was originated in Japan. 3. The lately developed Suwon No.3 and No.4 are best from the leaf producing point of view, but they are not found such a good varieties from the nutritive aspect. The result may be happened as poor because they were cut before spring sprout started. 4. Ro-Soh which was normally recognized as a poor variety, was also found as a poor nutritive and leaf producing variety. 5. The crude protein and crude fat components in the mulberry leaves decreased as the leaf maturity was progressed, but the crude fiber and crude ash components increased reversively in general view. It was also found that there were some specific changing nature by the mulberry varieties and could not rule them by just one conclusion. 6. During the air and soil dry season, the ash component increases but the hydrocarbon and moisture contents decrease considerably, and which resulted to the increase of mulberry hardness ratio and the decrease of sugar-protein ratio, eventually it causes the decrease of the nutritive value. It was also found that Ichi-Hei, Ro-Soh, and Suwon No. 3 had a strong recovering nature to their normal nutritive condition after raining. 7. Mulberry is of course a rich calorie diet, and is calculated as 50 to 60 Cal. per gram.

      • 작잠사료성분(작蠶飼料成分)이 조사(繰絲)에 미치는 영향(影響)

        최병희 ( Byong Hee Choe ),남중희 ( Chung Hee Nam ) 한국잠사학회 1965 한국잠사곤충학회지 Vol.5 No.-

        본 보고는 우리나라에서 작잠사료로 사용되는 몇 가지 종류의 사료성분을 분석하여 각 사료가 조사에 미치는 영향을 검토함과 동시에 새로 고안된 작잠견해서촉진제의 조사가능력을 시험한 것이고 그 실험결과는 다음과 같다. 1. 작잠사료의 화학적 조성은 대동소이하였으나 그 영양가분석 결과를 볼 때 상수리나무잎이 가장 우수하였고 견형질도 가장 좋았다. 기타의 것은 영양가도 대동소이하였다. 2. 수산칼슘함유량이 적은 사료에서 좋은 고치가 형성되는 결과를 보였다. 그러나 어느 사료를 먹거나 간에 견층중의 함유량은 거의 같았다. 3. 탄닌함유량이 많은 사료에서 좋은 고치가 형성되는 결과를 보였다. 그러나 견해서에는 별스러운 변화가 없었다. 4. 작잠견해서 촉진제로서 Tussah-lite를 고안하였으며 작잠사량비율은 6∼7%이였다. This report was prepared to find how various tussah silk worm diets effect for the worm nutrition, its cocoon and reelability, Meantime, it was attacked the reeling effect of newly developed tussah cocoon cooking chemical, Tussah-lite. The results obtained are as followings. 1. The chemical composition of various diets were almost even, but Quercus acutissima Carrathers was the best from the nutrition point of view. 2. It was found that the more Calcium Oxalate, the better cocoon was formed, but Calcium Oxalate in the cocoon layer was found as almost same amount in case of different diet was fed. 3. It was also found that the more tannin, the better cocoon was formed, but the cocoon reelability was found as almost same in case of different diet was fed. 4. The cocoon reeling effect of newly developed chemical, Tussah-lite, showed 6∼7% silk yield from the tussah cocoon.
