North Korea has shown the great reduction in the quantity of foreign trade since the collapse of the former USSER and the countries of Eastern Europe which was the major trade partners. The trade deficit of North Korea has gradually increased, which is acting as the man cause of its economic depression. North Korea devote all of its energy to the imort of grains and the introduction of crude oil for processing on consignment to overcome severe food shortage and energy shortage, deepening the degree of dependency on foreign countries further. The important fact is that South Korea has overtaken Russia and is emerging as the third trading partner next to China and Japan in terms of the quantity and size of trade. Especially, the size of trade exchange of agricultural products between South Korea and North Korea is drestically increasing. South Korea and North Korea have several favorable conditions that they can expand mutual interests by activating the trade of agricultural products it. South Korea and North Korea fail to get out of the deadlock in trade because of economic difficulty and political and diplomatic factors, but there is a high possibility that they may expand trades on mutually complementary items in the future.

Reduction and sulfidation reactivities of mixed metal oxides were investigated by using a TGA. Mixed metal oxides consisted of CuO as the main active material, SiO₂ as the support material and both MoO₃ and Fe₂O₃ as the additives. Each material was chosen based on the literature survey. CS (CuO/SiO₂) sorbents were prepared to investigate the effect of support material, and consisted of various composition of CuO and SiO₂. CMS (CuO-MoO₃/SiO₂) and CFS (CuO-Fe₂O₃/SiO₂) sorbents were prepared to investigate the effect of additives and consisted of various composition of CuO and additive. In CMS and CFS sorbents, a support material was 25wt% SiO₂ because the previous study showed that 25wt% SiO₂ was needed to maintain the activity in multicycle experiment. Simple physical mixing method was chosen as the sorbent preparation method. Chatterjee-Conrad method was used to evaluate activation energies of sorbents from TGA data. The activation energy of CS sorbents decreased in reduction reaction and increased in sulfidation reaction as SiO₂ content increased. Fe₂O₃ was more favorable than MoO₃ as an additive material in terms of reduction reaction rate.

1. 새로 육성된 4개의 대덕찰 찰옥수수 교잡종에 대한 간장은 대조구인 찰옥 1호보다 큰 반면에 개화기는 약 4∼7일 늦었으며, 모든 공시 교잡종의 주당 분얼수는 한 개이하의 무효분얼로 나타났다. 2. 새로 육성된 대덕찰옥수수의 이삭길이와 직경은 대조구인 찰옥 1호보다 크게 나타났으며, 특히 대덕찰옥수수 1호와 2호의 과피두께는 대구조보다 얇았고, 당도 역시 높게 나타나 우수 교잡종으로 평가되었다. Stem height of the new developed "Daedekchals" waxy hybrids were higher than check hybrid. Chalok #1, while days to tasseling were delayed about four to seven days. Number of tillers per plant of the these new hybrids including check were appeared to be one less as non-effective tiller. Ear length and diameter of the new waxy hybrids were longer and thicker than check, respectively. In addition pericarp thickness of the Daedekchal #1 and #2 among new developed waxy hybrids were thinner and sugar content were higher than check.

李珩九,姜孝信,鄭址昌 中央醫學社 1975 中央醫學 Vol.28 No.6

The influence of fruit of Lycium chinense Miller on the blood sugar levels and serum transaminase (SGP-T, SGO-T) activities from alloxan-diabetic rabbits were observed. The Lycii Fructus were extracted with methanol, and the extracted sample was orally administrated to normal and alloxan diabetic rabbits. As for the blood sugar levels and serum transaminase activities of normal rabbits no significant variation were detected by administration of the extracted sample. The blood sugar levels and serum transaminase activity of normal rabbits were significantly increased by administration of the alloxan. The increased blood sugar levels of 'the alloxan-diabetic rabbits were gradually decreased by administration of the extracted samples, and were returned to the control levels after 12 day. The increased transaminase activities in serum of the alloxan-diabetic rabbits were significantly decreased after 96 hours. According to the above results, it would be concluded that the extract of Lycii Fructus influences for the recovery of the increased amount of blood sugar levels and serum transaminase activities by alloxan.

The purpose of this study was to investigate the relationship between the dietary behavior-such as the knowledge of nutritive, dietary habit and food preference, etc. - and the state of health of the boys' and girls' middle school students. The study was analyzed by simple fregency, percentage. t-test, x2-test, dispersion analysis and person·s correlation in using the SPSS PC+ Package System by means of questionnare to 446 boys' and girls' middle school students in Chung Yang Kun and Kong Ju City in Chung Cheong Nam Do in Korea The results as follows : 1.The Knowledge of nuurition : most of the students think that they know a little about nutrtion. They have obtained the knowledge of nutrition from mass media or mother but they have not used them in their actural life. The scale of the nutritive knowledge of the students was relatively low(mean=7.14) and girl's was higher than boys' 2.They get three meal times a day. The most regular diet in a day was lunch and the irregular was dinner. The girls took diet irregularly than boys because of having no time to eat in the morning and want to take dinner with family. They think their problem is unbalanced diet(23.1%). They were apt to select delicious snacks(61.3%). The boys consider nutrition(20.2%) for snacks and girls consider taste(68.6%) 3.Their favorite foods material were chicken(85.7%), eggs(81.6%), youghurt(91.8%), cuttle-fish(93.3%), orange(96.9%), potato(87.4%), and dried laver(93.3%). They don't like eggs of guailo(41.0%), cheese(67.2%), oyster(63.5%), persimmon(24.2%) eggplant (55.6%), and green laver(25.3%). 4.Their favorite foods were Mandu(45.3%), beer soup(25.8%), Kimchi stew(47.8%), Chinese cabbage Kimchi(44.6%), Bulkoki(36.0%), Kokijorim(35.7%), Kalbijim(65.5%), Kokijorim(59.3%), Sauted rice(37.4%), soy-bean sprouts(44.4%), and Sauted cuttledfish(53.9%). 5.The average height was 161.6cm, the average weight was 52.0kg and girls and boys were in good health. There was no difference between boys and girls in the state of physical health, but boys were phychologically healthy. The students, who thke three meal a day didn't take an unbalanced diet. and who didn't take snacks were betteer in physical or mental aspects than students who take them irregularly. 6.There were correlation between the degree of perception and the score nutritive knowledge but the boys who think that they have lots of nutritive knowledge were actually low in nutritive knowledge score.

The present study examined the effect of dietary manipulations on five trained hockey player. The amount of energy intake is about 3,288kal/day in fat diet and about 3,309kal/day in carbohydrate diet, and the percentage energy contributions from carbohydrate diets, fat, and protein were 44.2/40.8/15.1 and 68.9/15.4/15.7 for fat and carbohydrate diets, respectively. Expiratory gases and blood responses to a prolonged treadmill run were determined following 7d on each diet. Free fatty acid(FFA), triglycerides, glycerol, glucose, and lactate were measured. Running time to exhaustion was not significant difference on both experiment diets. Plasma FFA levels were higher and glycerol levels were lower during the fat diet than during the carbohydrate diet. Other biochemical measures did not differ significantly among diets. These data suggest that endurance running of 80% VO₂max is so high for college hockey players that the difference created by two diets are not significant.
