This paper is considering on investigation of the single nature theory of Wangyangming. Most of all, His single nature's theory is the results of critical reflections on the nature theory suggested by Zhuxi's learning. His theory has two unique characteristics. First, in contrast to Zhuxi's arguments, WangYangMing emphasize the single 'QiZhizhiXing(氣質之性)' which unify 'XingjiQi(性卽氣)' with Gaozi(告子)'s 'ShengzhiweiXing(生之謂性)' theory, and present view that 'nature is only one'. Second, He regards The Four Virtue(四德) and The Four Sprout(四端) as 'revealed virtues(表德)', defines them as 'already produced(已發)' virtues at the same time. Through this course, he tries to dismantle various nature and virtues which were constructed based on the criterion of 'XingerShang(形而上)' and 'XingerXia(形而下)'. The reason why he unify all the nature theory which Zhuxi had suggested as one nature's category, is not based on the theocratical interest but on the practical interest. In other words, he tries to provide the more practical methodology which each learner can directly embody and cultivate his own nature in his or her daily life.

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).

The problem of temperament is not much of importance in Philosophical discussion compared to subjects such as liqi and Xingli. However, temperament is of great importance in practical study theory. "The reason people study is because they want to change their temper." the scholars said. The theory of change in temperament in neo-Confucianism is pursued in two directions. The first is to purify the temperament in a clear state. The second is to overcome the bias of temperament and lead it to a state of the middle path. The former is the study that purifies the murky water and turn it to a clear state, as the bead in it is brilliantly revealed. The latter is the study of maintaining without bias toward the path of nature itself. While the ultimate purpose of temperament change is to realize bright nature intact without obstruction of temperament, it goes through two processes specifically. It is to maximize intellectual and practical ability and overcome bias in inclination and character. The purification of temperament and the realization of Zhong are in sync with the orientation of the theory of temperament change.

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.

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.

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.

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.
