가잠란배자발육과정(家蠶卵胚子發育過程)에서 Glucose와 phosphorus의 변동(變動) 및 방사선(放射線)에 의한 영향(影響)
김원경 ( Won Kyong Kim ),임영우 ( Young Woo Lim ) 한국잠사학회 1969 한국잠사곤충학회지 Vol.10 No.-
As a result of analyzing the change of material substance of all sorts biochemically and comparing the control with γ-ray irradiation (800r, 400 min), incubating the silkworm egges (bombyx. mori. L.) as the objective in the process of growth of embryo shortly before hatching, the following conclusion has been found. 1. Glucose has shown the increase of 281.2 mg/g in control during the pigment stage and it has shown the increase of 179.6 mg/g in γ-ray irradiation during the same period. The difference in quantity between the former and the latter is due to the fact that the growth of embryo has been influenced by the radio active. Glucose has changed with phosphorus the other way round. 2. Control organic phosphorus has shown the increase of 5.23 mg/g during the Byong B or KI A in which organ and tissue in the embryo has been formed. Organic phosphorus in γ-ray irradiation has shown the increase of 5.73 mg/g during KI B. Inorganic Phosphorus has shown only a little change in the control and γ-ray irradiation. The phosphorus in both has shown a little quantity in the γ-ray irradiation in early period of incubation. After the Ki A embryo, it has increased rapidly and it has increased till the hatching more continually than in control. The about results of the research will be helpful and instructive to the betterment and improvement, breeding and management of animals and plants.

In answer to the increase of demand for the safety in railroad, the safety activities are tried out. According to "KORAIL Instruction number 2001-49", the project for developing Integrated Centralized Traffic Control Center has been carried out and the safety activities are guaranteed by documents named "Safety Plan" and "Safety Requirements" from this project. However the development system is not enough for the full safety activities. Therefore this paper we describes the relationship of safety activities and development systems and proposes the efficient direction of safety activities.
1962년 추잠기(秋蠶期)에 발생(發生)한 가잠(家蠶) 및 야생곤충(野生昆蟲)의 경화병균(硬化病菌)에 대하여

이 시험은 예비시험에 지나지 않고 그 병원성에 대하여서는 익년에 다시 하여야 한다. 그러나 지금까지 하여온 결과를 종합하여 요점을 들면 다음과 같다. (1) 누에의 녹강병과 야외곤충의 경화병 시체는 공통된 병원균 Nomuraea pracina와 Isaria spp에 의하여서 걸리는 것이라고 짐작이 된다. (2) 송충이는 Isaria spp에 의하여 이미 그 구제방법으로 실시하고 있어서 다른 야외곤충에도 그 포자가 전파되어 있음을 짐작할 수 있다. (3) 흰불나방 유충은 경화병균에 의하여 침범되지 않는 것 같다. This is a forecasting report for die experiment on agent of disease to be carried on next year. 1. Muscardine of the silkworm and wild insects are supposed to be caused by a common agent, Nomuraea Pracina and Isaria Spp. 2. In the view of using the method of spreading the spores of Isaria spp to control the Dendrolimus Spectabilis Butter, the other wild insects are also supposed to be contaminated by that. 3. Hyphantria Cunea Drury does not seem to be infected by fungus of Muscardine.
잠종제조상(蠶種製造上) 회전족(回轉族)의 효과시험(效果試驗)

改良簇과 回轉族에 각각 300頭의 熟蠶을 上簇시키고 이것을 4區로서 設置하여 그 후의 용體 蛾 産卵에 대하여 調査하였다. 1) 改良簇에서는 橫作繭이 63%에 대하여 縱作 斜作은 37%나 많이 나타났다. 2) 용體異常은 改良簇에서 많이 나타나 그 후의 모든 形質에 不良한 結果를 招來하였다. 3) 死용에서도 改良簇이 많다는 것은 縱作이라는 그 現象이 蠶용에 어떠한 不利한 生理作用을 주는 것이라고 생각된다. 4) 發芽狀況은 回轉族이 확실히 많다. 5) 正常卵蛾의 數는 回轉族이 많다. 6) 産卵數에 있어서도 回轉族이 많고 體內殘卵數는 改良簇이 많았다. 이것은 回轉族의 쪽이 排卵을 더 많게 하고 있다는 結論이라고 할 수 있다. 7) 1000類에 대한 産卵重은 回轉族이 훨씬 많다. 指數로 表示하면 回轉族 100에 대하여 改良簇은 85가 되므로 실지 單位生産量에 있어서 回轉族이 훨씬 有利하다. 그리고 橫作, 斜作, 種作의 別과 또 回轉族과의 産卵重 比較에서 分散分析結果는 縱作 斜作은 가장 적고 따라서 이것이 많이 생기는 改良簇에서는 回轉族에 比하여 生産量이 적어진다는 이유도 여기에 있는 것이다. 8) 經濟的으로 打算할 때 回轉族은 값이 高價이나 單位 蠶種生産量이 많으므로 族代를 支出하고도 더 利益이 많은 것이다. Author investigated the effects of a grate type mounting on the pupae, moth and deposit of silkworm eggs. The results are as follows. 1) The grate type mounting was more useful for the silkworms to spin the cocoons transversely than the other type. 2) Many abnormal pupae appeared in the control, and in next generation all the silkworm characters of them were poor. 3) The fact which many dead pupae occurred in the control seems to be that the cocoons spun vertical1y did harm to the physiological reactions of the pupae. 4) The moth rate emerging out of the cocoons was higher in the grate type mounting than in the control. 5) Many moths which laid normal eggs were in the grate type mounting, and also laid a lot of eggs. Therefor, author made an infference that the grate type mounting had accelerated the laying eggs. 7) The total weight of eggs produced from 1000 cocoons was heavier in the grate type mounting(index=100) than in the control (index=85). As shown in table of analysis of vanriace, above phenomenon might be relative with one of the reasons why the cocoon spun transversely could be more produced in the grate type mounting than in the control. 8) Even though the grate type mounting costs higher than the other one, it may be available because the egg weight per unit was considerably heavier in its treatment. So the cost of egg production will become cheaper.

1. Ascorbic acid는 병B 배자까지는 점차적으로 증가하고 그 후에는 감소함을 알 수 있었다. 2. Triglyceride 및 total cholesterol은 병A 배자까지 증가하고 그 후는 감소함을 알 수 있었다. 3. Phospholipid는 병A 배자에서 감소하고 병B 배자에서 증가 다시 감소하였다가 점청기배자에서 부화직전까지 증가함을 알 수 있었다. 4. Free Fatty acid는 병A 배자에서 감소하고 병B 배자와 기A 배자에서 증가를 나타내고 다시 감소하였다가 부화직전에 증가하는 것을 알 수 있었다. As a result of investigating the change of Ascorbic acid and Lipid which have a relation with metabolism of a silkworm egg in the process of the growth of embryo is silkworm eggs. The following facts have been found 1) Ascorbic acid has gradually increased before the period of the Byong B embryo and it has decreased after period of Byong B embryo. 2) Triglyceride and Total cholesterol has gradually increased before the period of the Byong B embryo and it has decreased after period of the Byong B embryo. 3) Phospholipid has gradually decreased before the period of the Byong A embryo and it increased during the Byong B embryo and decreased again at same stage. It has increased from the head pigment of embryo to hachting. 4) Free Fatty acid decreased during the Byong A embryo stage and increased from the Byong B embryo stage to the Ki A embryo stage and decreased again and increased shortly before the hachting.
