The effects of Pueraria flos (PF) and Pueraria radix (PR) water extract on the hepatic alcohol metabolic enzyme activities were examined in rats that were orally administered ethanol (25% v/v, 5g/kg body weight/day) for 5 weeks. The PF and PR water extract were supplemented in a diet, based on 1.2 g or 2.4 g of raw PF or PR/kg body weight/body. Alcohol administration without the PF or PR supplementation significantly decreased net weight gain, feed intake and feed efficiency ratio. However. both dose of the PF of PR supplementation resulted in significant enhancement of growth and suppression of increased relative weight of liver, brain and heart by alcohol administration. Activities of hepatic alcohol dehydrogenase and microsomal ethanol oxidizing system were higher in the alcohol treated group than in the normal group, while aldehyde dehydrogenase activity was significantly lowered in the alcohol treated group. The hepatic metabolic enzyme activities altered by alcohol administration were normalized by both doses of PF or PR supplement. Hepatic monoamine oxidase activity and hydrogen peroxide, which were significantly higher in the alcohol treated group than in the normal group, were also decreased by the supplementation with either PF or PR. These results indicate that low-or high-supplementation of either water extract PF or PR may alleviate ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.

As a result of studing on the "shashen(沙蔘)", we could reach conclusions as follows. 1. Shashen is the root of "lunyeshashen(潤葉沙蔘)", "kuoyeshashen(闊葉沙蔘)", and its same generic plants that belong to Companulaceae. In china people has used twenty-four species as a shashen together with other generic plants, in korea sixteen species as a shashen. 2. At first, in the "Shen Nong's Herbal(神農本草經)" it was recorded and then in the "Benchingfengyuan(本經逢原)" divided into "nanshashen(南沙蔘)" and "beishashen(北沙蔘)". Recently, nanshashen called shashen belongs to Companulaceae and have strong efficacies of clearing away heat from lung, resolving phlegm, beishashen belongs to Umbelliferae and have strong efficacies of nourishing stomach, nourishing yin. 3. Shashen is the root of Adenophora stricta Miq., and yangru(羊乳) is that of Codonopsis lauceolata Bentham et Hooker, jini is that of Adenophora remotiflora (SIEBOLD et ZUCCARINI.) MIQUEL. From a efficacious point of view, it is the characteristics that shashen have efficacies of nourishing yin and clearing away heat from lung, supplementing stomach and promoting production of body fluid, resolving phlegm and relieving cough, eliminating pus and abscess, expelling wind and pruritus, jini have those of clearing away heat and toxic material, resolving phlegm and yanru have those of nourishing yin and moistening lung, resolving phlegm and eliminating pus, clearing away heat and toxic material, stimulating milk secretion. 4. After being recorded as "zhimu(知母)" in Shen Nong's Herbal, the alias of shashen was recorded as kuxin(苦心), shimei(識美), huxu(虎須), baishen(白參), zhiqu(志取), wenhu(文虎), baolishen(保利參), paoshen(泡參), jibantui(鷄半腿), yangponai(羊婆妨) and so on. Moreover shashen was named after its characteristics of that it grows well in the sandy soil and as a wushen(五參) with a renshen(人蔘) its form is different from that of wushen but their chief virtues are alike. 5. In the numerous medical books, xinyeshashen(杏葉沙蔘) regarded as nanshashen. It was called as the alias of jini, so I thouhgt that it was wrong xinyeshashen to be regarded as nanshashen. 6. It was used shashen for renshen, renshen was used to treat lung-cold syndrome by its efficacy of tonifying yang and shashen lung-heat syndrome by its efficacy of nourishing yin, the reasons of that because shashen had amount of sap, its properies and flavours of herbs are light and clean. 7. The constituents of shashen were essential oil, starch, shashen-saponin, furocoumarin, xanthotoxin(ammoidin), inulin, sugar, mucus and have efficacies of resolving phlegm, promoting production of body fluid, immunomodulational and antibiotic efficacies. above results indicated that the origin of shashen and substitutional plants was various. Their efficacies are somewhat alike, but there were characteristic efficacies each other. Nowadays they are used together with, so we should know the characteristic efficacies of them and then we using them clinically, more deep discrimination and experimental support shoud be accomplished.

This study investigated the effect of Puerariae Flos (PF; flower of Puerariae plant) and Puerariae Radix (PR; root of Puerariae plant) water extracts on the activities on the activities of ethanol-metabolizing enzymes and free radical generating/scavenging enzymes of brain in ethanol-treated rats. Five groups of male Sprague-Dawley rats were orally administered ethanol (25%, v/v) 5 g/kg body weight/day, and sacrificed 5 weeks post treatment. PF and PR water extracts were supplemented in a diet based on 1.2g (I) or 2.4 g (II) raw PF or PR/kg body weight/day. Alcohol dehydrogenase activity of brain was significantly lowered in PF of PR groups, whereas aldehyde dehydrogenase activity was significantly higher in PR groups than those of control and PF groups. Cytochrome P-450 content, aminopyrine D-methylase and aniline hydroxylase activities were decreased in both PF and PR groups compared to control group. Aldehyde oxidase and xanthine oxidase activities tended to decrease by Puerariae plant extract supplemented goups and degree of decrease predominated in PRI. Superoxide dismutase and glutathione S-transferase activities were increased in PF or PR groups, whereas glutathione peroxidase and catalase activities were significantly decrased by Puerariae plant extracts supplement. These results indicated that supplementation of PF or PR lowers free radical generating enzymes activities. It was suggested that the activities of ethanol metabolizing emzymes and antioxidant enzymes in brain can be enhanced by PF or PR supplement in ethanol-treated rats.

In the situation of rapid industrialization based on the lopsided development of economy since 1960, Korean rural society has faced a crisis of disruption. As a result, the civilian government has tried a few actions to change the circumstance. However, it is said that the coral polices were not satisfactory. Those who were concerned with the rural problems of these days argue that it is necessary to adopt new policies and further to change the policymakers` philosophies concerning the matter. The arguments are certainly based on the beliefs that the sound policies come from the sound philosophies. This study aims to analyze the existing rural polices and their policymakers` philosophies and to design of a new paradigm. For the purpose, this study was set there specific objectives: First, to overview the moor points of Quantitative Utilitarianism of Jeremy Bentham and the Social Justice Theory of John Rawls, the contrasting frameworks of the moral philosophies; Second, to trace the major or trade of the rural policies since 1960s in Korea; Third, to analyze the policymakers` philosophies reflected on the rural policies; Fourth, to design a new paradigm of the rural policies. This study mainly adopted descriptive method based on the various source of government and non-government statistics, white papers and other researches. The major findings of this study may be summarized as follows: 1. The historical epochs of the rural policies in Korea was divided into the periods: (1) An organizational and institutional establishment for self-reliance of main crops and the New Village Movement $(1969{\sim}70)$; (2) An initiation of `open-door` policies to the foreign farm products $(1970{\sim}80)$; (3) Completion of the UR meetings and the recommendations of the Rural and Fishery Development Commission (1980-present). 2. It was found that the philosophical foundations of coral policies were directly reflected from the utilitarianism of the national development. Under the philosophy it was the modem sector of economy that was to spearhead the national development, and the rural sector was situated to the peripheral position and hardly in the spot-light. Therefore, it may be said that the present situation of the rural society was largely rooted in the model of economic development. 3. As a new direction of the coral policies, many studies were focussing on the NTC (non-trade concerns) functions of agriculture for the present and future society. The researchers argue that the cost of protecting and supporting agriculture and rural society may be higher than that of the burden which the nation should be bear in the case of failure of agriculture. Although it tray be true, however, it should be noted that the argument is another type of utilitarianism which prevailed in the past. As a philosophy of rural policies, utilitarianism is straight forward and persuasive, however, it has also limitations in terms of relativism in broad sense or social justice in specific manna. 4. This study suggests to set the philosophical foundations of rural policies on the basis of Rawl`s Theory of Justice mentioned earlier. It emphasizes the inviolability of social justice which was neglected for the national benefits timing the period of development dictatorship in 1960s and 1970s. The principles of social justice for coral people were identified as twofold; (1) The principle of the t equal liberty; (2) (a) Difference principle, (b) The principle of fair equality of opportunity.

The main purpose of this paper is to make a case for the availability of pragmatist ethics by showing the differences between utilitarianism and pragmatism. In this paper, drawing on Dewey's view, I show that Bentham and Mill were doomed to failure because they both regarded moral conduct not as a process but as a fixed act, the remarkable differences between their views notwithstanding. Besides, I also show that pragmatism distinguishes itself from utilitarianism by its focus on the aspect of the amendment of a conduct rather than its attainment. Pragmatist ethics works on the assumption that moral conduct arises only in conscious experience. What pragmatists mean by consciousness is not an ability just given to haman, but a function emerging from the human interaction with his environment. Therefore, morality is extended from and restricted by experience, because it is grounded in concrete experience, but not in the transcendental nor a priori realm. Since pragmatism suggests the possibility of "ethics without principles" in that it works through the way which successfully rejects the traditional absolutist ethics, while avoiding the downslide to a nihilistic form of skepticism. Thus, it may serve as a third view that overcomes a seriously divergent situation of the current ethical arguments. In other words, starting from the very nature of experience, pragmatist ethics offers a 'bottom-up' ethics, instead of a 'top-down' one. This reconstructive reading of pragmatism away from utilitarianism is expected to offer a more comprehensive account of our moral experience in the pluralistic world of diverged values.

The development of contemporary utilitarianism can be taken to be an aggregation of many attempts to surmount the limitations of classical utilitarianism. In these attempts, contemporary utilitarianism suggests alternatives to 'hedonism' and 'act-utilitarianism' which have been regarded as the common essential elements of classical utilitarianism. First, contemporary utilitarianism replaces the concept of 'happiness' or 'pleasure' in the classical utilitarianism with that of 'desire-fulfillment' or 'preference-satisfaction'. Through this replacement, contemporary utilitarianism tries to avoid the skeptical challenge to the mental state theory inherent in the classical concept of utility, and also to provide a more extensive conception of utility for a more satisfactory explanation of human welfare. Second, the development of rule-utilitarian theories which can evade the criticisms about 'counter-productivity' and 'counter-intuitiveness' of act-utilitarianism constitutes another important trend of contemporary utilitarianism. Characteristically, rule-utilitarian theories developed in the contemporary utilitarianism grope for some utilitarian system that can embrace socially accepted general norms. Lastly, contemporary utilitarianism responds to the criticisms related the problem of justice by reinterpreting the first principle of utilitarianism. This reinterpretation is an attempt to explain the egalitarian basis of utilitarianism through Bentham's dictum 'everyone counts for one, none for more than one'. It seems true that many influential criticisms in the latter half of 20th century cast a deep shadow on utilitarianism. But through the above attempt, contemporary utilitarianism proceeds to a better explanation of human welfare.

A new baekji(Angelica dahurica Bentham et Hooker) variety, Baekji l, was developed through a pure line selection at the Gyeongbug Provincial RDA during the period of 1990 to 1995. The variety was characterized to have high plant height. Long root length and large root diameter as compared with a check varicty of Bonghwa baekji but emergence date, flowering date and leaf number of Baekji l was similar to that of the check variety, and it was also more tolerant to nematode and heat stress. Peeled root color of Backji l was yellowbrown but number of the lateral root of the variety was greater. The dried-root yield of Baekji l in yield trial, regional adaptation trial and farmer's field trial was always $21\sim31%$ higher than that of the check variety.
