Data on the crude protein requirements of elk doe are nonexistent and the data are essential for their management in Korea. Therefore, this study was conducted to evaluate the crude protein requirement for maintenance of elk doe. Three female elk deer were used in 3 × 3 Latin square design with three diets containing three levels of crude protein (CP) that contained low crude protein (approximately 12%), medium crude protein (15%), and high crude protein (18%). Each three elk doe trials included a 14-day preliminary period and a 5-day collection period. Crude protein intake was 4.83, 6.26, and 9.00 g/d for 12%, 15%, and 18% of CP level, respectively. Crude protein balances were 1.04, 1.41, and 4.14 for 12%, 15%, and 18% of CP level, respectively. The maintenance requirement for CP from the regression equation between CP intake and CP balance were 3.70 g/BW^0.75.

Objectives : The purpose of this study was to analyze and identify the problems of the changes in regulations that are relevant to approval, notification, and review of herbal medicinal preparations and crude drug preparations. Methods : I collected the regulations of approval, notification, and review of medicinal products mostly from official gazettes, analyzed enactment and amendments regarding herbal medicinal preparations and crude drug preparations, and studied it from the view point of Korean medicine field. Results : Regulations in regards to approval, notification, and review of herbal medicinal preparations and crude drug preparations were first established in 1978. Herbal drugs started to be categorized as crude drug preparations in 1981 and the regulatory outlines were completed in 1999. From 2008 to 2012, the regulatory standards that let crude drug preparations be new drugs from natural products were established. Through those procedures, the followings became crude drug preparations: 1) wholly new prescriptions that are not recorded in Korean Medical Classics, 2) prescriptions that are recorded in Korean Medical classics but prepared with new standard, composition and efficacy, 3) prescriptions that are recorded in Korean Medical classics but prepared with new formulation, and 4) herbal drugs. In case of herbal medicinal preparations, however, only regulations that are related to 1) drugs prepared with new compositions that are not recorded in Korean Medical Classics, 2) drugs with same prescription and same formulation, and 3) drugs with new formulation were arranged. Conclusions : Actual circumstances on crude drug-oriented regulations regarding approval, notification and review and future forms of prescription and drug administration in Korean Medical Institutions can be expected due to expansion in range of herbal medicinal preparations and shrink in that of on-site preparations. Reasonable improvement in efficient usage of modernized herbal medicinal preparations in Korean medical institutions and prospective cooperation from related pharmaceutical industry are needed.

The present study has been undertaken to investigate the effects of crude ginseng extract added to food on the lipid composition in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 group, each group receiving a different diet for 10 weeks ; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 0.5% crude ginseng extract, basal diet plus 15% lard and 0.5% crude ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, triglyceride, total cholesterol, HDL-cholesterol, free cholesterol. The results obtained were as follows : 1. Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but crude ginseng extract caused an increase in food efficiency ratio. 2. Lard supplementation group showed increase in the weight of liver, kidney, spleen, but another groups did not. 3. The contents ratio of triglyceride, total cholesterol in serum of lard-fed group showed significant increase compared to controls and but the simultaneous supplementation of crude ginseng extract and lard decreased significantly than those of lard-fed group. 4. The contents of free-cholesterol and ester cholesterol in serum of the simultaneous supplementation of crude ginseng extract group decreased as compared with the lard single fed group. 5. Crude ginseng extract single-fed groups. 6. The ratio of contents of VLDL, LDL-cholesterol in serum was significantly high in the only lard containing group and alcohol group, the crude ginseng extract supplemented group was showed lower tendency than only lard and alcohol group. The above results suggest that crude ginseng extract would prevent the metabolic disease by improving hyperlipoidemia.

This experiment was conducted to compare the productivity of five silage corn varieties. Corn varieties were Pioneer 3144(P 3144), 3160(P 3160), 3282(P 3282), 3352(P 3352) and Suweon 19(S 19) and were seeded on May 2 and harvested on August 15. Ratios of stalk, leaf and ear, chemical composition and yields of nutrients were investigated in respective corn part. Experimental design was accepted by Latin square arrangement with five replicates and each plot had twenty two plants. The results obtained were as follows: 1. Crude portein, crude ash and nitrogen free extract(NFE) contents of whole plant ranged from 6.32 to 7.18%, 5.16 to 7.43% and 52.62 to 57.90%, respectively, and there were no significant(P>.Ol) differences between varieties. Crude protein and NFE content were the highest in ear between corn parts. 2. Crude fiber conent of whole plant ranged from 18.98 % to 24.01 %, and was the highest in suweon 19 and the lowest in P 3352(P<.01). Crude fiber content was the highest in stem and the lowest in ear, However, crude fat content(2.03-3.66 %) vice versa. 3. Yields of organic matter, crude protein, crude fat, NFE and TDN per 10a were the greatest(P< .01) in P 3282, however crude fiber yield was the highest(P<.Ol) in P 3352. 4. Ratios of different part to total dry matter yield ranged from 12.7 %(P 3352) to 17.8 %(P 3160) for leaf, 44.5(P 3352) to 66.9 %(P 3160) for stem and husks, and 16.9 %(P 3282) to 42.8 %(P 3352) for ear, and there were significant differences between corn varieties(P<.Ol). Consequently, P 3352 has the greatest nutrient yields, particularly by ear, and P 3282 has a great nutrient yield by stem. This result suggested that could be appear a better character of silage corn by hybridization of this two corn varieties.

In the proximate composition of the yams of home product, wild yam was most abundant in crude lipid and crude protein, and those content in the cultivated yams, cultivated long yam and cultivated short yam were similar. Cultivated long yam is the richest in crude ash. African yam had more crude lipid and crude protein compare to those of home product yams. Especially, the amount of crude lipid in African yam was four-fold of home product yams. In the mineral content, Ca was the richest mineral in four kinds of yam. The rest of mineral were in order of Fe, Mn and Zn. Among the home product yams, the Ca content of wild yam was higher than that of cultivated yam. The contents of Fe, Mn and Zn were also high in wild yam compared to cultivated yam. In the composition of free sugars, the sucrose content is the highest in wild yam, cultivated short yam and African yam. in order The fructose content was the most abundant in cultivated long yam and the next was sucrose. The composition of free fatty acids were in order of lactobacillic acid, palmitic acid and palmitoleic acid. Crude saponin contents of the home products were almost similar levle, but crude saponin of wild yam was more abundant than that of cultivated yam. And crude saponin of African yam was much more abundant compared that of other home product yams. there is not much difference in the kinds of saponin from the home product yams. However, the amount of each saponin from the home product yams was different. In case of African yam, 'b' saponin did not appear and 'e' saponin was higher compared with home product yams. In African yam, the bitter taste from ethyl acetate layer was the strongest, and the next was n-butanol layer. It is possible that there was a powerful UV absorption material in the bitter taste of ethyl acetate layer and also supposed that there were saponin and phenol is material.

The objective of this paper is to examine whether it is feasible to introduce an crude oil futures contract on domestic commodity exchange in order to minimize the price risks of imported crude oil. In addition. this study suggests the policy issues to promote futures trading and the alternatives to use foreign energy compares the five criteria to evaluate the feasibility of crude oil futures trading on the domestic exchange. Related to the possibility of successful futures trading of imported crude oil on the domestic exchange, they are evaluated as follows: it is highly possible to succeed for the aspects of price volatility, potential market size or liquidity, and commodity homogeneity; but it is inappropriate for the aspects of deliverable amounts and market power or market structure. Therefore, it is concluded that trading a new futures contract for the underlying imported crude oil on the domestic exchange is inappropriate. For the policy issues and the hedging alternatives, first, it is urgent to establish an atmosphere for futures trading by promoting spot trading. Second, for the case of futures trading on the domestic exchange it is important to consider the simultaneous hedging of crude oil price and foreign exchange risks and mutual offsetting mechanism with major foreign exchanges. Third, for the case of futures trading on foreign exchanges it is reasonable to regard cooperation among concerned companies, government support for futures trading and direct participation into futures trading by the government.

Compositional characteristics and origin of polycyclic aromatic hydrocarbons(PAHs), which should be strongly regulated for environmental protection in the crude oils and petroleum products, have been investigated by gas chromatography-mass spectrometry(GC/MS). In the crude oils analyzed, two-rings compound(naphthalene) of PAHs was detected around $72.3\sim93.5%$, but five- or six-rings compound of PAHs was not detected. In the crude oils analyzed, the molecular ratio indices of Phe/Ant(phenanthrene/anthracene)>15, Fla/Pyr(fluoranthene/pyrene)<1, BaA/Chr(benzo (a)anthracene/chrysene)$\leq0.4$ could be effectively applied, and we found that the origin of PAHs was petrogenic sources. Total PAHs concentrations in the crude oils were increased with increasing API gravity and with decreasing sulfur contents of the analyzed crude oils. Five- or six-rings compound of PAHs were not included in ail petroleum products except bunker-C. Furthermore, the molecular ratio indices of Phe/Ant(phenanthrene/anthracene) vs. Fla/Pyr(fluoranthene/pyrene) could be effectively applied as the standard for the PAHs contamination criterion at the other Korean areas.

This studies were conducted to find out the possibility of utilizing red pepper seed as resources of food fats, the research method was designed to make a comparison between crude and refined oil, and the results of the studies are as follows : The red pepper seed contained 28% of crude fat and 21% of crude protein. The main fatty acids of red pepper seed oil were linoleic acid(72.10~72.31%), palmitic acid(12.81~13.28%) and oleic acid(9.47~10.48%). The linolenic acid content was so small that is will not influence the autoxidation of the red pepper seed oil. The major triglyceride type of crude and refined oil of red pepper seeds were C52 and C54. The other types were found in a small quantity. The sterol composition of crude oil was $\beta$-sitosterol, campasterol, stigmasteral and brassicasterol,in the quantity order. after refining, brassicasterol was not detected, and the content was decreased by one six and one eight. The toropherol composition of crude and refined oil, tocopherol analog was composed of three kinds $\alpha$-, ${\gamma}$-, $\delta$-, but no $\beta$-form. the quantity of ${\gamma}$-, $\alpha$- and $\delta$-tocopherol were 162.91, 83.72, 43.98mg% respectively. The Quantity of and capsaicin in crude oil was 1,296 ppm, and it was reduced consicerably by refining and removed completely after the process of redeodorization.
