Researches about the Horaknonjaeng(湖洛論爭) have succeeded by focusing on the Osangnonbyeon(五常論辨)?Mibalnonbyeon(未發論辨). In a way of these researches, philosophic thought of Gwon Sangha(權尙夏) is dealt in a comparison and in that process his philosophic thought seems to be known. However, these researches are treating several thoughts so it is difficult to find accurately what point describes the position of his thought in the korean confucian thought as origin of Hohak(湖學). In this paper, therefore, I examine Gwon Sangha's theory of mind-nature by focusing on the understanding the concept of mind-nature in Hansujaejib(寒水齋集) and find its position in history of thought as an origin of forming Hohak. Before 1709, Horaknonjaeng don't break out, Gwan Sangha had been formed that Inmulseongsangi(人物性相異) of Osangpyeonjeon(五常偏全) based on the understanding of the fact that ensuring of Bonyeonjiseong(本然之性 性善) in Gijiljiseong(氣質之性) and under this influence scholars of Hohak formed thoughts and insisted Osangpyeonjeon(五常偏全 人物性相異) during Horaknonjaeng. In the point of Simseongilmul(心性一物) focusing on nature, he didn't admit the Jujaeseong(主宰性) of mind. This is the efforts of finishing the controversy of Simseongigi(心性二岐) and the efforts of finding the relation between Simseon(心善). Such thoughts are set before the Horaknonjaeng and basing on these influences, scholars of Hohak formed their thoughts and insisted the Gibulyongsa(氣不用事 未發氣質有善惡).

Nei Ching referred to as a canon of Chinese medicine is a comprehensive life philosophy that applied the life principle of the universe to the human body to combine the philosophical concept with the human nature as well as the functions of the body's organs. The book formed a complete system of a Qi Philosophy by using the medical terminology and theory based on the concept of Qi. It is remarkable that the Qi philosophy of Chang Tsai, who is a Neo-Confucianist and representative scholar of Qi philosophy in the era of Song Dynasty, has been influenced by the Qi philosophy in Nei Ching and developed into a Confucian school Furthermore, Chang Tsai's theory, in effect, impacted upon the rise of Qi Determination of the Human Nature in Medicine of Zhang Jie Bin who is a profound thinker in the era of Ming dynasty. As mentioned above, both traditional philosophy and medical philosophy in china in regard to Qi Theory have interacted and developed each other. This paper is to make a comparative study of the Qi Determination of the Human Nature proposed by Chang Tsai and Zhang Jie Bin and to trace the orgin of the Qi Determination of Human Nature.

Youlgok's thoughts on mind are represented both in his one-road theory of mind, nature, emotion and will and in his one-way theory of Li riding on a dynamic Ki. The one-road theory has two meanings. First, it means that mind, nature, emotion and will are not separate things, but those three things other than mind belong to mind, which only different phases of mind. Second, it means that human desire and moral will, inborn nature and dispositional nature, four clues and seven emotions are not sets of mind opposing each other forever, but sets of mind which can be sublated in the end. The one-way theory of Li riding on a dynamic Ki explains the relation of mind and nature in terms of Li and Ki. In Youlgok's theory, Ki(mind) is the subject of operating dynamics and Li(nature) is the content of operated results. Nature appeared through operating mind is emotion. Li riding on a dynamic Ki means both that Li superintends Ki(operates Ki's standard), and that it realizes itself through Ki. In a word, mind is the subject realizing nature, and mind operates under the control of nature. In this way, Youlgok pays attention on both Li's norm and Ki's dynamic.

Batch experiments were performed to investigate the effects of volumetric mixing ratio(v/v) of two substrates, food wastes(FW) and waste activated sludge(WAS). In batch experiments, optimum mixing ratio for hydrogen production was found at $10{\sim}20$ v/v % addition of WAS. CSTR(Continuous Stirred tank reactor) was operated to investigate the hydrogen productivity and the microbial community under various HRTs and volumetric mixing ratio(v/v) of two substrates. The maximum yield of specific hydrogen production, 140 mL/g VSS, was found at HRT of 2 day and the volumetric mixing ratio of 20:80(WAS:FW). The spatial distribution of hydrogen producing bacteria was observed in anaerobic fermentative reactor using fluorescent in situ hybridization(FISH) method.

The researcher conducted this study to investigate what special meaning does an emotion experience program, a Confucianism philosophical thinking, has for Sunwoo(善友), and based on what structure it unveils a good clue of Sunwoo(善友); and to reveal the structure of philosophical counselling treatment simultaneously. Thus, the researcher performed an "emotion experience program for 3 weeks, targeting 22 research subjects and collected the data of their experience. As for date analysis, a phenomenological analytic method of Colaizzi (1978), one of qualitative research methods was used. It was because the phenomenological analytic method of Colaizzi was suggested to derive common properties of whole research subjects rather than those of individual research subject, which could help develop the theories of philosophical counselling treatment. The finding of the analysis revealed the intrinsic structure of the phenomenon which the research subjects experienced through "an emotion experience program" was reborn as 'unfamiliarity and suspicion', 'burden', 'recognition of a method and a need', 'self-reflection', 'awareness of nature and the correct behavior', 'joy and pleasure', and 'rebirth as a valuable existence'. These were categorized to examine the structure of philosophical counselling treatment. The findings revealed the treatment went through the precesses: 'the start of learning and intentional guidance', 'reflection', 'enlightenment', 'Sugichiin(修己治人)', 'freedom', and 'transcendence. Considering the purpose of Confucian philosophy is living valuable life and the accomplishment of objectives is based on the transcendence, realizing preallotment and putting it into practice, the structure of emotion experience by the research subjects is appropriate for the purpose of Confucian philosophy and the process of objective accomplishment.

Since Noron(老論) had organized in the period of Sookjong(肅宗), it constantly had led the political situation of Choson until Choson(朝鮮) perished as the grasping political power. Studies and thoughts development of Noron can be devided into four periods. First, the term of politics of faction of the period of Sookjong. Second, a period of Youngjo(英祖) and Joungjo(正祖). Third, a period of politics of power(勢道政治). Fourth, the latter term of 19century. We can look into an origin and development aspect in outline by dividing like this. The general character of Noron can be summarized by the respect of Song Si-yeol(宋時烈, 1607-1689), the theory of a party of a man of virtue(君子黨論) based on the theory of moral civilization of Choson(朝鮮中華論), the succession of Lee i(李珥; 1636-1684)'s neo-confucianism, rejecting all teaching that does not conform to neoconfucianism and protecting right studies, and oppression of Roman Catholic. The noticeable scholars of Noron were Kwon sang Ha(權尙夏; 1641~1721), Kim chang hyup(金昌協; 1651~1708), Lee jea(李縡; 1680~1746) etc. These scholars of Noron following Song Si-yeol had tried to raise "Learning of the Way"(正明道) by respecting Zushi and removing injustice(尊朱子攘夷狄), also believed people should embody moral values in their society and country. and possessed an will guiding to stabilize the country by rejecting uncivilization(尊王攘夷). Above all, they insisted, the King of Choson should rule with 'lighting heavenly reason'(明天理). Also they insisted the King and countrymen should together strive to recover civilization of moral humanity and destroy uncivilzation. But gradually they lost the motive and purpose of moral politics in the seventeenth century. Finally Noron Byeokpa(?派) take over the reins of government. It resulted in the bad effect of politics of autocrat(勢道政治) having their own way to use power of authority after death of Jungjo(正祖). The peculiar character of Noron politics can valued as the extreme aspect of 'according of politics and scholarship'(政學一致).

In this study, Anaerobic sewage sludge in a batch reactor operating at $35^{\circ}C$ was used as the seed to investigate the effect of pretreatments of waste activated sludge and to evaluate its hydrogen production potential by anaerobic fermentation. Various pretreatments including physical, chemical and biological means were conducted to utilize for substrate. As a result, SCODcr of alkali and mechanical treatment was 15 and 12 times enhanced, compared with a supernatant of activated sludge. And SCODcr was 2 time increase after re-treatment with biological hydrolysis. Those were shown that sequential hybridized treatment of sludge by chemical & biological methods is most efficient process for sludge treatment. The pre-treatment activated sludge was tested to conform hydrogen production potential in batch experiments. When buffer solution was added to the activated sludge, hydrogen production potential increased as compare with no addition.

For the use of skipjack tuna cooking drip (STC) as a source of functional seasoning, the STC was hydrolyzed with various commercial enzymes, such as Alcalase, Flavourzyme, Neutrase and Protamex, and its hydrolysate was also investigated on the food component characteristics. The hydrolysate incubated with Alcalase for 30 min (HA30) showed 56.8% for angiotensin I converting enzyme (ACE) inhibitory activity and 1.18 for antioxidative activity, which were high or similar compared to the other enzymatic hydrolysates. There were no differences in ACE inhibitory activity and antioxidative activity among HA30, two-step enzymatic hydrolysates, and ultrafilterates (molecular weight cut off, 10 kDa). The HA30 was very stable on the digestive enzymes, such as chymotrypsin, pepsin, trypsin according to the TCA (trichloroacetic acid) soluble index. The results suggested that skipjack tuna cooking drip could be used as a source for preparing functional seasoning sauce.

This study was carried out to investigate antioxidative, antimicrobial activity and the effect on hepatotoxicity in various extracts of Artemisia iwayomogi. The herb has been used widely for jaundice, hepatitis and liver cirrhosis in chinese medicine. Solid yield by various extraction solvents, 18.1%, was the highest in water extract. To find antioxidative activity in Artemisia iwayomogi was estimated radical scavenging effect by DPPH method in various extracts and change of the POV(peroxide value) of various extracts added in soybean oil during 20 days at $60^{\circ}C$. Radical scavenging effect by DPPH method was the most effective in methanol extract. Added 1,000ppm water extract and methanol extract in soybean oil, the POV of them, 46.8(meq/kg) and 50.8(meq/kg) were lower than that of control, 79.1(meq/kg), during 20 days storage. After antimicrobial activity of various extracts of Artemisia iwayomogi on bacteria was carried out by paper disc method, it found that the ethanol extract was the strongest activity on Vibrio parahaemolyticus. In vivo experiment was to investigate the effect of Artemisia iwayomogi water extract(AIWE) on hepatotoxicity by carbon tetrachloride$(CCl_4)$ in rats. The experiment groups were divided into five groups for recovery(for 3 days) and three groups for protection(for 10 days) in rat liver. The weights and morphological changes of liver and the body weight were examined in each groups. Compared with $CCl_4$ treatment groups$(CCl_4\;only)$, liver and liver/body(%) weights of AIWE pretreatment groups for 3 days and AIWE posttreatment groups for 10 days were declined. In macrography, fibrious exudates and swelling of liver were decreased in AIWE treatment groups. Accumulation of lipid droplets and necrosis of hepatocytes were also decreased in AIWE treatment groups in microscopically. In these results, AIWE seems to enhance hepato-protective and recoverable effect on $CCl_4$ induced hepatotoxicity in rats.
