We found out that there exists threshold dose for the decreased platelet count when we apply change of the platelet count to the defense of the ultrasound experiment. Those diminution is definite effects from the defense of the ultrasound. The number of the platelet count is decreased when we are exposed to ultrasound simultaneously. This should not be occurred. It is easy to use the number of the platelet count in the measurement of the biological dosage and intensity in high dosage relatively due to definite quantative relationship. The biological index to understand synergic effects. which are present when two harmful environmental factors are operating at the same time is functionally assending and antagonistic. There are scattered many factors as physical, Chemical, or physiochemically elements which are harmful to human body in the environment in consideration of ultrasound and the other factors. This experiment is demonstrating that we can use the change of the platelet as an index representing synergic effects of ultrasound.

The purpose of this study is to prove the analgesic effects of apitoxin and its mechanism via jaw-opening reflex(JOR) and measuring expression of mRNA in Phospholipase and Tryptophan hydroxylase(TPH) using RT-PCR. The experiments were carried out on Sprague-Dawley rats(300-400g) and mastocytoma(P-185 HTR) for JOR and RT-PCR, respectively. Rats anesthetized with thiopental sodium (80mg/kg) were used in the Tooth Pulp stimulation induced JOR. The amplitude of a digastric electromyogram (dEMG) was recorded during the stimulation at an intensity of 1.5 times the threshold for JOR. Apitoxin used in this experiment was diluted with normal saline by 1:1000. Apitoxin was injected intravenously into the test group while normal saline to the control group. However, it was injected directly into the cell of mastocytoma. We referred to base sequence registered in Genbank in designing primers for RT-PCR. The results were as follows; (1)Compared with control group, analgesic effect started to show right after Sprague-Dawely rats were treated with apitoxin($71.50{\pm}8.08$) and lasted for 50 minutes. (2)As a result of the experiment of RT-PCR, we witnessed significant changes in the degree of expression of phospholipase or rate-limiting enzyme of biosynthesis of prostaglandins with $10{\mu}g/ml$ apitoxin.($31.74{\pm}18.98%$, P<0.05) (3)As a result of the experiment of RT-PCR, we witnessed significant changes in the degree of expression of TPH or rate-limiting enzyme in biosynthesis of serotonin with $10{\mu}g/ml$ apitoxin.($131.37{\pm}16.87%$, P<0.05). These results suggest that $10{\mu}g/ml$ apitoxin have the most analgesic effects. This study showed that apitoxin has analgesic effects and held good for 50 minutes. The injection of apitoxin has brought out changes in the degree of expression of phospholipase and TPH. These results strongly suggest that analgesic mechanism by apitoxin is closely related to prostaglandins and serotonin.

This study was carried out in order to evaluate the economic impacts of and to determine the market weight of korean native cattle cross-bred by charolais. For this study, 15 farms were surveyed which raised one or more cross-bred korean cattle by charolais in Kanghwa county, and 12 farms were also investigated which reared korean native cattle in Kwangju and pochun county in Kyunggi province. Specifically interview surveys were conducted, using constructed schedule on two times; Sep. 15, 1980 - Sep. 20, 1980 and Feb. 10, 1981 - Feb. 15, 1981. The results obtained in this study are summarized as follows; 1. Improvement of productivities of cattle through the research and experimentation proved to be one of the most important measures to increase the farm house-hold income because most of the cattle farms raised only one or two tattles. 2. The average daily gain of cross-bred cattle up to 18 months old was 1.09 ㎏, and it was about 42 percent more than that of korean native cattle (0.77㎏) at farm level. The feed efficiency of cross-bred was moth higher than the korean cattle by 20 percent. Average live-weight of cross-bred cattle was 632㎏, which was 45 percent more than that of the korean cattle (436㎏) at 18 months. 3. Gross receipts, management cost and income per head of cross-bred korean were 1,435,000won, 726,000won, and 709,000won, and these were higher than that of the korean native cattle by 45, 44 and 42 percent. respectively, at 18 months old. 4. At 18 months, the management cost per ㎏ gain of the cross-bred cattle was 588 won, and the production cost per ㎏ gain was 1,394won. These were lower than those of korean native cattle by 10 and 20 percent, respectively. 5. To figure out the profitable market weights of cross-bred cattle, production function and profit function were derived. It was observed that other factors such as labor, roughage, building and equipment costs except the concentrate were not significant to determine the liveweight of cattle. Under the assumption that other factors except the concentrate were constant the following equation was derived to determine the maximum profitable market weight; Wtc=628.3+0.001(Px/Py)-5,580.3(Px/Py)² where Wtc is the liveweights of the cross-bred cattle (㎏), Py is the concentrate price (won/㎏), and Px is live-weight price (won/㎏) . 6. In concluding, (a) the cross-bred cattle showed higher fattening capability. (b) they were more profitable than korean native cattle, (c) maximum profitable market weight of cross-bred cattle at current feed and cattle prices was about 600㎏, and (d) the break-even weight of cross-bred cattle at 17 and 18 months were 476 ㎏ and 511㎏, respectively.

This study was carried out to determine the best condition of roughage supply for the efficient management of farm land for forage production. To investigate the present situation of feed production in forage crop field, 31 farms were surveyed in Chonnam province during summer season of 1985. The results obtained were as follows; 1. Production of forage crops in upland was more profitable than that of other crops such as red pepper, garlic, Irish potato, barley and soybeans. 2. The optimum combination of feed for a milk cow was determined as 2,000㎏ of concentrate and 4,435㎏ of hay when a cow produced 5,000㎏ of milk a year. 3. Minimum land requirement for self-sufficiency of roughage to feed a cow was 0.17㏊ of forage crop field without feeding any rice straw, and 0.14㏊ of forage crop field with feeding 1,000㎏ of rice straw a year. 4. Reasonable cropping pattern of forage with Italian ryegrass, sorghum-sudangrass hybrid, corn, rye, radish and rape were suggested for typical dairy farming to attain efficient use of land and self-supply of feed.

콘첼만의 ‘종말 지연’에 대한 비판적 논구

조광호(Cho, Gwang Ho) 한국신약학회 2017 신약논단 Vol.24 No.3

누가의 종말론은 구속사, 이스라엘, 교회, 성령, 하나님 나라 사이의 내적 관계성까지 포괄적으로 고려해야 하는 주제이기 때문에 누가의 신학 가운데 특히 어려운 테마이다. 콘첼만(H. Conzelmann)이 1954년에 쓴 Die Mitte der Zeit(‘때/시대의 중간’) 덕분에 누가의 종말론은 수 십 년간 학자들 사이에서 격렬하게 토론된 단골 주제 중 하나가 되었다. 각 학자들의 의견을 파악하고, 누가-행전의 주요 본문들을 검토해 보면 재림 지연과 임박한 종말 두 요소가 병존한다는 사실을 알게 된다. 이와 관련하여 지연과 임박이라는 양 날의 검을 가지고 과열된 열광주의와 식어가는 재림 기대, 두 전선을 상대로 동시에 싸웠다는 해석, ‘상황의 시차’로 이해하는 입장(누가 자신의 시대에 임박한 종말이 필요하기 때문에 전 시대인 누가-행전에서는 지연을 강조함), 미래적 종말을 권면의 차원으로 이해하려는 해석 등 다양한 의견이 제시되고 있다. 필자는 누가의 종말론이 현재적이냐 미래적이냐는 논의보다는, 누가가 승천을 강조한다는 사실에 좀 더 주목할 필요가 있다고 생각한다. 누가는 승천과 재림 사이의 ‘지금’을 종말론적 구원의 때로 이해한다. “예수는 하늘로 가심을 본 그대로 오시리라”는(행 1:11) 언명을 통해 현재 확장되고 있는 하나님 나라와 종말에 궁극적으로 세워질 나라 둘 사이의 긴밀한 연관성이 보증된다. 공동체에게는 때의 문제가 아니라 ‘지금 무엇을 해야 하느냐’가 중요하다. 승천한 예수는 하나님 우편에서 자신이 위임한 권세를 제자들이 잘 사용하고 있는지 살펴보고 계신다. 필요에 따라 직·간접적으로 개입하시며 하나님 나라의 확장을 위해 힘을 보태고 있다. 승천은 사람들로 하여금 종말론적 긴장을 유지하며 하나님 나라 건설에 투신하도록 자극하는 역할을 한다. 덧붙여 구속사에 대해서도 약간의 정리할 필요가 있다고 본다. 재림 지연이라는 문제를 해결하기 위한 방편으로써 누가가 이를 창안해 내었다는 콘첼만의 견해에 동의할 필요는 없다. 그러나 누가가 역사 속에서 하나님의 구원 섭리가 구체적으로 ‘어떻게 실현되고 전개되어 가는가’에 대해 관심을 가졌다는 점에서 누가는 어떤 복음서 기자보다도 구속사에 관심을 가졌다고 볼 수 있다.
