On the basis of the presented data which took boy and girl students and their subjects in Korea, Japan and Republic of China n 1987, the authors intended to compare and analyze the physique-growths(body height and body weight) of the three nations' students from May 1 in 1989 to April, 30, 1990 with the application of the medians of Korea, Republic of China and Japan. The result are as follows : A. Physical growth and development 1. Body height(cm) In case of male students, Korean students are superior in their body heights to Japanese students when they are before the year 10, but from 10 to 20, both of nations' students are same. And them students of Republic of China are all inferior to those of Korea and Japan through all these ages. In case of girl students, Koreans are taller than Japanese and Repulic of China through all these ages. Chinese are inferior in their heights to Korean and Japanese through all these ages. The interchange ages of the body height occured in the both sexes of 9.5-12.5 in Korean, 9.5-12.5 in Republic of China and 9.0-12.0 in Japan. During this period, girls are taller than boys, but after this period boys are taller than girls, Maximum growth age per year for male in Korea is the ages 12-13(8.71cm) and these for female is the ages 11-12(6.90cm) of Korean students. 2. Body weight(kg) In case of male, Japan students show similar growing degrees through all the ages, and the students of Korea and Republis of chinese indicate a little lower degree than Japan. In case of female, the similar phenomena are showed. The interchange ages of the body weight occured in the both sexes of 9.0-13.0 in Korea, 105-13.5 in Republic of China, and 10.0-12.5 in Japan. The MGA per year for male is the ages 12-13(7.01kg) in Korea, 13-14(5.46kg) in Republic of China, and 11-12(5.5kg) in Japan, while for female is the ages 11-12(2.72kg) in Korea, 10-11 and 11-12(4.39kg) in Republic of China, and 11-12(4.39kg) in Republic of China, and 11-12(5.1kg) in Japan, respectively.

A field study was conducted during the summer time of 2002 to determine compositions of volatile organic compounds (VOCs) emitted from vehicles and to develop source emission profiles that is applied to CMB model to estimate the source contribution of certain area. Source emission profile is widely used for the estimation of source contribution by the chemical mass balance model and have to be developed applicable fur the large1 area of estimation. This study was aimed to develop source emission profile and estimation of source contribution of VOCs after application of the chemical mass balance (CMB) receptor model. After considering the emission inventory and other research results for the VOCs in Seoul, Korea, the sources like vehicle emission(tunnel), gas station (gasoline, diesel), solvent usage (painting operation, dry cleaning, graphic att), and gas fuels were selected for the major VOCs sources. Furthermore, ambient air samples were simultanceusly collected from 09:00 to 11:00 for four days at eight different official air quality monitoring sites as receptors in Seoul during summer of 2001. Source samples were collected by canisters, and then about seventy volatile organic compounds were analyzed by gas chromatography with flame ionization detector (GC/FID). Based on both the developed source profiles and the database of the receptors, CMB model was intensively applied to estimate mass contribution of VOCs sources. Examining the source profile from the vehicle, the portion of alkanes of VOCs was highest, and then the portion of aromatics such toluene, m/p-xylene were followed In case of gas fuel, they have their own components: the content of butane. propane. ethane was higher than any other component according tn the fuel usage. The average of the source apportionment on VOCs for 8 sites showed that the major sources were vehicle emission and gas fuels. me vehicle emission source was revealed as having the highest contribution with an average of 49.6% and followed by solvent with 21.3%, gas fuel with 16.1%, gasoline with 13.1%.

Produkthaftung ist die durch Produkt, also durch Wirtschaftgu‥ter ausgelo‥ste Haftung. Eine Definition der Produkthaftung im Sinne des Produkthaftungsrechts enthaβlt die Verpflichtung, fu‥r Scha‥den zu haften, dieaus der Benutrung, aus den Ge-oder Verbrauch von fehlerhaHen Produkten entstehen. Da der Herstellereines Produkts nicht nur seinen unmittelbaren Vertragspartnern SorfEltspflicht schuldet, geho‥rt es zum haftungs-rechtlichen Kernbereich der Produkthatung einen Schadensersatz auch gegenu‥ber Dritten zu gewa‥hrleisten.Fu‥r die Untersuchung zur Produkthaftung als rechtliche Aufgabe der internationalen Industrie haben dieVerfasser vier mo‥gliche Themenbereiche ausgewa‥hlt. In einem ersten Kapital werden haftungsrechtliche Grund-sftze im modernen Produkthaftungsgesetz(und Produkthaftungsgesetz - Entwurf) und deren Tendenz der Ent-wicklung unter Beru‥cksichtigung der letzten internationalen Geseftgebung dargestellt. Das zweite Kapital derUntersuchung ist der Produkthaftung in den USA gewidmet. Die Produkthaftung in der EG wird im drittenKapital behandeit. Das vierte Kapitel wird sich mit der Produkthaftung in Japan beschliftigen.Aus der Untersuchung lassen sich im wesentlichen folgende herausstellen 1. Als wesentliche Tendenz unterstellt das moderne Produkthaftungsgesetz(und produkthaftungsgesetz -Ent- wurf) der yerschuldensunaba‥ngigen Gefa‥hrdungshaftung. Mit der Gefa‥hrdungsprodukthaftung sind fu‥rinternationale Industrie ku‥nftig erhebliche Belastungen verbunden. 2. Eine weitere Tendenz gegenu‥ber dem bisherigen Recht besteht darin, daβ jede Person, die sich alsHersteller ausgibt, sowie der Importeur, der aus Ausla‥nder einfu‥hrt, und auch der Lieferant der Haftungunterworfen werden. 3. Der Hersteller muβ fu‥r Entwicklungsrisiken nicht haften, wenn der Hersteller daru‥ber beweisen kann,daβ es sich im konkreten Fall um ein Entwicklungsrisiko handelt. 4. Von der Haftung ausgenommen werden landwirtschaftliche Naturprodukte, z. B. Erzeugnisse des Bodens,der Tierrucht, der Imkerei und Fischerei sowie Jagdfeugnisse, die nicht einer ersten Verarbeitung unto

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

배추 plug육묘 조건을 알아보기 위하여 상토 종류, 질소시비수준, plug트레이 배수공수준을 달리하여 실험한 결과를 요약하면 다음과 같다. 1. 유묘출현율은 A상토<B상토<C상토의 順으로 높았고, 질소시비수준은 무비구에서 높고, 시비구에서는 90∼90ppm수준에서 높은 편이었으며 배수공수에 따라서는 배수공이 적은 128공구가 출현율이 높았다. 2. 幼苗의 葉발생도 A상토<B상토<C상토 순으로 높았고, 질소시비수준은 다비구(150ppm구)에서 엽수 5배로 최대엽수를 나타내었고, 배수공수에 따라서는 배수공이 적은 128공구가 높았다. 3. 엽장의 길이는 A상토구는 128공구에서 질소시비수준 120ppm에서 6.98cm로 가장 길었으며, B상토구에서 128배수공구의 시비수준 150ppm에서 12.41cm로 가장 길었고, C상토구에서도 128배수공구의 시비수준 150ppm에서 12.88cm, 200배수공구에서도 9.29cm로 가장 길었고 무비구에서는 공히 가장 짧았다. 4. 葉幅도 엽수와 엽장과 비슷한 경향으로 기비로 사용된 질소의 시비수준이 증가할수록 엽장이나 엽폭이 증가하여 B상토구의 150ppm 시비구에서 4.80cm로 최대치를 나타냈으며 시비량이 감소할수록 엽폭도 줄어드는 경향이였다. 5. 뿌리의 신장은 A상토구의 128배수공구에서 질소질 함량이 90∼120ppm수준의 범위내에서 신장이 양호하였으나 150ppm시비구에서는 불량한 반면, B와 C상토구에서는 90∼150ppm 모두에서 양호하였다. 6. 생체중과 건물중도 상토조성, 질소질비료 및 트레이 크기에 따라 모두 크게 영향을 받는 것으로 나타났으며 C상토구의 150ppm시비구에서 주당 3.0g의 생체중에서 최대치를 보였고 건물중 역시 C상토구의 150ppm시비구에서 4주에 600mg의 생체중의 증가를 보여 최대의 기록을 나타냈고 질소질의 농도 150ppm이 생체중 및 건물중 증가에 가장 효과적인 것으로 나타났다. The experiments were conducted to develop ideal substrates for the production of good quality in cabbage plug and also to improve the media with low or non environmental pollution by blending and mixing artificial substrate including peat moss, coir, perlite, vermiculite, carbonized rice hull and zeolite. In effects of soil substrate combination, nitrogen concentration and tray cell size on growing of 'Baekro', chinese cabbage, the ratio of seedling emergency in all fertilizer block was higher than non-fertilizer of nitrogen by 80%. The number of leaves were most increased in the 150ppm nitrogen solution of B block(coir 50%, vermiculite 10% and perlite+carbonized rice hull-zeolite 40%) and C block(coir 40%, vermiculite 20% and perlite+carbonized rice hull+zeolite 40%). The leaf length and leaf width were similar with that result in the number of leaves. Rooting condition was the best in the 90∼120ppm nitrogen solution of A block(TOSILI No1, SHINAN-JEONGMIL(Co)) in 128 tray cell size. The fresh weight and dry weight were increased as the order A<B<C in soil combination, were increased in the fertilizer which has more nitrogen concentration and were increased higher in 128 than 200 tray cell size, and chlorophyll concentration was the highest in the 150ppm nitrogen solution of A and B soil combination.

메리골드(Tagetes patula L. 'Orange Boy')를 통해 오염지 식생복원과 동시에 양호한 식생경관 조성재료로서의 가능성을 알아보기 위해 본 실험을 수행하였다. 메리골드 'Orange Boy'에 있어서 Zn과 Cd 100+20㎎·L^-1 처리구에서는 GA_3 와 uniconazole은 생체량 및 Zn과 Cd의 축적에는 영향을 주지 않았다. 생장조절제 무처리구의 Zn과 Cd의 200+40㎎·L^-1 처리구에서 대조구의 20%로 건물량이 감소하였다. Zn과 Cd의 농도별 혼용처리에 따른 체내 무기성분 T-N, P, K, Ca, Mg함량은 뚜렷한 경향이 없었고, Zn의 축적은 뿌리와 잎에서 각각 1,227 및 903㎎·㎏^-1, Cd의 경우 줄기와 잎에서 각각 89.7 및 77.4㎎·kg^-1의 최대의 농도를 보였다. The use of plant-based systems to remediate contaminated soils has become an area of intense scientific study in recent years and it is apparent that plants which grow well in contaminated soils need to be identified and screened for use in phytoremediation technologies. This study was conducted to determine the effects of various combinations of Zn and Cd on growth and mineral concentrations of Tagetes patula L. 'Orange Boy'. With 100㎎·L^-1 Zn + 20㎎·L^-1 Cd, GA_3 and Uniconazole did not increase the plant biomass, and accumulation of Zn and Cd Total dry weight with 200㎎·L^-1 Zn and 40㎎·L^-1 Cd was 20% that of control. There was no significant to T-N, P, K, Ca, and Mg contents in leaf, stem, and root. The Zn contents of root and leaf were 1,227 and 903 ㎎·kg^-1, respectively. While the Cd was accumulated different site compared to Zn, the highest accumulation place were stem (74.4 ㎎·kg^-1) and leaf (89.7 ㎎·kg^-1).

尹衡植,申大休,崔載春,權重浩 慶北大學校 1982 論文集 Vol.33 No.-

This experiment was carried cut to investigate the relationship between nitrite and ascorbic acid contents in two kinds of tomato fruits namely, Bokwang, Suekwang, which were different distinguished in growth periods during culture. The results obtained were as follows. The nitrate content in two kinds of tomato fruits was relatively higher in Bokwang than Suekwang. It indicated high content as 5.8-12.5 ppm in flesh and 0.3-2.5 ppm in gelatinous pulp. In the beginning of growth period, nitrate content in flesh was 50-62.5ppm, and in the latter period was 21.3-38.4ppm. In the case of gelatinous pulp, it was decreased from 14.0-16.2ppm in the beginnig period to 9.3-10.7ppm in the latter period. In the case of nitite, there was no difference between two varieties. Nitrite content during growth increased from 0.15ppm to 0.21ppm in flesh and from 0.06ppm to 0.1ppm in gelatinous pulp. There was no difference between two varieties during growth in total ascorbic acid content and its concentration was 24.2-27.5mg in gelatinous pulp and was 13.8-18.6mg in flesh. The difference between two parts was about 10mg. In the changes of nitrate and nitrite content in tomato fruits, nitrate was decreased, whereas nitrite content was increased. In the changes of nitrate and ascorbic acid content in tomato fruits, nitrate content was decreased but that of ascorbic acid was increased slightly. In the changes of nitrite and ascorbic acid content in tomato fruits, nitrite content was increased and that of ascorbic acid was slightly increased too.
