This research examines the recognition of nature as identified by Zhuangzi through the man of truth. Zhuangzi defines inactivity as an act of nature and personifies it as the man of truth, a holy man who achieves salvation. It is the stage that is united with nature by breaking out of secular restriction and achieving the absolute liberal spirit. The man of truth is the origin enabling all the acts of nature. And since the existence of all living things is connected, the change of life and death complies with the operation of nature. It is an irresistible destiny for all human beings. Therefore, the duty of nature recognizes the life and death of all creation into a single perspective. In this sense, the feelings of joy and sorrow that human beings feel are unnecessary. When following the duty of nature and destiny, which is to break out of secular desire and empty the mind, it is possible to go to the stage of futility and enjoy a silent and comfortable life. Zhuangzi explains it as living free from worldly cares, which is the stage of 'Soyoyoo(逍遙遊)'. In this thesis, the principles of courtesy and the virtue of Confucianism are stated and are contrary to the concept of futility asserted by Zhuangzi. But, a different approach could be attempted which recognizes a superman who is even more evolved from the man of truth. The philosophical ideology of Zhuangzi could be a necessary factor for modern people and his oriental natural spirit should be highly appreciated.

This study was conducted to find out the effects of over seeding using new grass varieties orchardgrass 'Kordione' and 'Onnuri', and tall fescue 'Greenmaster' on botanical composition and dry matter productivity from 2013 to 2016 in low productivity hilly pasture, middle area of Korea. There were used 3 grass seed mixture types made of different compositions and amounts {T1: control - no over seeding, T2: tall fescue (TF) 'Greenmaster' $18kg\;ha^{-1}$, orchardgrass (OG) 'Kordione' $9kg\;ha^{-1}$, Perennial ryegrass (PRG) 'Linn' $5kg\;ha^{-1}$, and Kentucky bluegrass (KBG) 'Kenblue' $2kg\;ha^{-1}$, T3: TF 'Greenmaster' $9kg\;ha^{-1}$, OG 'Kordione' $18kg\;ha^{-1}$, PRG 'Linn' $5kg\;ha^{-1}$, and KBG ' Kenblue' $2kg\;ha^{-1}$, T4: TF 'Greenmaster' $9kg\;ha^{-1}$, OG 'Onnuri' $18kg\;ha^{-1}$, PRG 'Linn' $5kg\;ha^{-1}$, and KBG 'Kenblue' $2kg\;ha^{-1}$}. In the botanical composition of grassland, T1 nearly remained constant in other seasons while ratio of weeds were increased in summer season. T2 was better than control (T1) in portion of grass ratio, which has increased by 80%. In the early time of establishment, the portions of OG were increased in T2, but TF rate was increased after 3 years later when grass was established. T3 and T4 showed a very similar patterns, grass ratio had increased by 80% and the portion of KBG had increased as time passed. T2 ($129,763kg\;ha^{-1}$) was showed the highest dry matter yield than other treatments (T1: $6,756kg\;ha^{-1}$, T3: 9641, and T4: 10,738) in 2016.

The purpose of this article is to explain the conceptual changes that the notion of Haewon (解冤) has undergone by examining the evolution of the usages of Haewon. In order to achieve this purpose, I reviewed the conceptual connotations and denotations of Haewon contained in data from the Joseon Dynasty (Section 2), the Japanese colonial period (Section 3), and the scriptures and major preceding research of Daesoon Jinrihoe (Section 4). The research results described in this article are as follows. First, Haewon is a term with historical, social, and cultural characteristics. This means that Haewon, a term that has been used since the Joseon Dynasty, was a concept used to solve collective problems but could also be applied on the individual level. This further means that, if culture is regarded as a collective consciousness or as a collection of material products, Haewon would be a term that contained social and cultural aspirations. Second, Haewon is not a concept that has been impervious to innovation throughout its history. This can be confirmed by the fact that Haewon's scope of application has changed depending on the problem domain (legal, natural disasters, an institutional domain, etc.). Third, Haewon has converted into religious language a doctrinal system that came about after the emergence of Jeungsan. This means that previously the concept of Haewon was mainly used at the legal level in the Joseon Dynasty, but after the emergence of Jeungsan, it became a term in religious language and in doctrine. The materials of Daesoon Jinrihoe show that this concept of Haewon was expanded to be included at the doctrinal level. These research results show a historical shift in the ideological thought contained in the concept of Haewon. As a term in religious language that is included in a doctrinal system, Haewon has an extension of denotations that is applied to the world beyond individuals and societies, yet it maintains connotations of resolving grievances. This concept of Haewon mediates the transformation of the world and creates a rationale by which training and ethical practice are necessary components of that process of transformation.

This thesis is a study on the symbolism of 'Yeondo', a prayer for the souls in purgatory of Korean Catholic Church as a 'psychic container' for the spiritual transformation in the psyche from a perspective of analytical psychology. Yeondo' could be the 'rites of passage' of the last judgement for the souls in purgatory which is in between the heaven and the hell. And both the bereaved and the dead go through the stages of separation, transition and incorporation which are the schema of the 'rites of passage'. In particular, they have a special sense of solidarity at the stage of transition, a middle state. The symbolic process of 'Yeondo' is a spiritual transformation of recovery of paradise which could access by the confusion of death, purification and the rebirth. A spiritual reborn process of death and rebirth takes place by contacting the collective unconscious. In 'Yeondo', the death is not the end of life but the beginning of the eternal life. The confusion and disintegration caused by death can be purified and start incorporating. The rites of a paradise recovery has the meaning of trying constantly for the recovery of a wholeness. Praying for the blessing of God and a help from saints in paradise for the sake of the dead means to require conscious cooperation for the Self-realization. Integrating and recognizing unconscious also means something beyond the conscious. The blessed souls in purgatory recovers the paradise experiencing specific purifying process heading towards Self. Going into the center, abyss of unconscious will be recognized as an absolute part of oneself. One becomes the inner man, the transformed personality who is reached by the path of self-knowledge, the kingdom of heaven within oneself and can have the transpersonal energy, which enables to access to God's world and union with God. All desire and the will become one with God. In the final analysis, praying for the blessing of God and a help from saints in paradise for the sake of the dead becomes the path for the more and more conscious expansion of the alive. Therefore, 'Yeondo' as an initiation is the individuation process of the alive and the dead to reflect on themselves.

This study evaluated the antifungal activity of varying concentrations of water-soluble extracts from native plants (Vitex rotundifolia, Tetragonia tetragonoides, Artemisia capillaris, Hibiscus hamabo and Ficus carica) against Stemphylium vesicarium, Penicillium italicum, Sclerotinia sclerotiorum, Pythium ultimum, Botrytis cinerea, Rhizoctonia solani and Colletotrichum gloeosporioides. Mycelium growth of pathogenic bacteria generally decreased in a concentration-dependent manner following treatment with the water extracts from donor plants. Closer analyses indicate varying inhibitory capacities depending on the type of donor plant and pathogenic bacteria. Specifically, mycelium growth of S. vesicarium varied depending on the concentration of the water extracts from T. tetragonoides (r = -0.857, p<0.01) and A. capillarys (r = -0.868, p<0.01). Also, P. italicum and V. rotundifolia (r = -0.833, p<0.01), S. sclerotiorum and V. rotundifolia (r = -0.862, p<0.01), A. capillaris (r = -0.902, p<0.01), B. cinerea and T. tetragonoides (r = -0.896, p<0.01) showed an inverse relationship. The rate of mycelial growth inhibition of pathogenic bacteria analysed are as follows: P. ultimum 94%, B. cinerea 50%, C. gloeosporioides 80% in 100% treatment of T. teragonoides. A. capillaris inhibited S. vesicarium by 43%, P. ultimum by 90%; H. hamabo inhibited P. italicum by 50%, S. sclerotiorum by 26%, and F. carica inhibited R. solani by 74%. Total phenol content with antifungal activities are as follows: A. capillaris 16.15 mg/g, F. carica 7.81 mg/g, V. rotundifolia 6.18 mg/g, H. hamabo 5.25 mg/g, T. tetragonoides 4.41 mg/g, and total flavonoid content is as follows: A. capillaris 27.57 mg/g, V. rotundifolia 12.49 mg/g, F. carica 11.45 mg/g, H. hamabo 5.77 mg/g, T. tetragonoides 5.08 mg/g.

Fermented vinegars using pear was compared according to the appled side materials. Quality characteristics of three kinds of the fermented vinegars (pear vinegar, PV; pear black rice vinegar, PBV; pear mint vinegar, PMV) were investigated, which includes pH, total acidity, colors, the contents of sugar, amino acids, total polyphenol, and total flavonoid, ${\alpha}^{\prime}{\alpha}-diphenyl-{\beta}-pycrylhydrazyl$ (DPPH) radical scavenging ability, and sensory evaluation. Brown rice vinegar (BRV) was used as a control. The pH and total acidity of the fermented pear vinegars were significantly different showing the range of 3.17~3.43 and 4.01~5.05%, respectively (p<0.05). The sugar contents of PV and PMV were significantly higher than other vinegars (p<0.05). L, a, and b values were the highest in PV, PBV, and PMV, respectively. Among the four vinegars, the essential amino acids were the highest in PV with the order of lysine, isoleucine, valine, and threonine. Besides, the fermented pear vinegars have many non-essential amino acids such as glutamic acid and aspartic acid. The aspartic acid content was the highest in PV while glutamic acid content was the highest in BRV. The total polyphenol content was the highest in PV while total flavonoid content was the highest in PBV. The DPPH radical scavenging ability (%) was the highest in PV. In sensory evaluation, PBV showed the highest color, taste and overall preference scores. These results show that pear would be desirable to prepare high-quality vinegars and functional foods.

This study was conducted to survey the epidemiological characteristics and the isolated strains for pathogenic E. coli which was the major causative organisms for food poisoning occurred at school food services in the Gyeonggi-do area during the past three years. We investigated 19 accidents of food-borne disease outbreaks by pathogenic E. coli at school food services from 2010 to 2012. Food-borne disease outbreaks by pathogenic E. coli were usually occurred at direct management type (18 accidents, 95%) and high schools. For the seasonal factors, 13 accidents (65%) were occurred in June to September, especially the end of August and September after the summer holidays. The first patients were occurred on Wednesday (7 accidents, 37%) and Thursday (7 accidents, 37%), and they were mainly reported on Thursday (7 accidents, 37%) and Friday (5 accidents, 26%). The exposure of risk was estimated in Monday (4 accidents, 21%), Tuesday (7 accidents, 37%) and Wednesday (4 accidents, 21%), and kimchi (5 accidents, 50%) was estimated as the food of the high risk responsible for the outbreaks. 98 isolates of pathogenic E. coli consisted of PEC (50%), ETEC (34%), EAEC (15%), and EHEC (1%). The antibiotic resistance of pathogenic E. coli showed in the descending order of ampicilline (40%), nalidixic acid (37%), trimethoprim/sulfamethoxazole (24%), and tetracycline (19%). The antibiotics of second and third generation cephalosporins, cabarpenem, aminoglycosides, and second generation quinolones had antimicrobial susceptibilities and cefalotin, ampicillin/sulbactam and chloramphenicol showed medium resistance at 29%, 25%, and 6% respectively, and 70% of isolates were resistant to more than one antibiotic. By the PFGE analysis, they were classified into nine major groups and 31 profiles with 57% pattern similarity. It was very difficult to find the correlation of antimicrobial susceptibilities and genotype in the small scale-food poisoning, but the similarity of antimicrobial resistance and PFGE patterns in the large scale-food poisoning enabled the outbreaks to estimate the same pathotype of E. coli derived from identical origins.

This study traces the development of physic gardens in Korea and explores their significance in the history of landscape architecture. For this purpose, records related to physic gardens from medical sources from the period of the Three States to the Joseon dynasty, when herbal medicine was systematized as a field, were searched. Physic gardens had been developed by the time of the late Goryeo and early Joseon dynasties, in the 13th and the 15th centuries. Yakpo(kitchen gardens for medicinal herbs) were cultivated by a group of new high-level officials in the late Goryeo dynasty, when an increasing interest in hyangyak(native herbs) emerged under the influence of the Neo-Confucian perspective on nature, which emphasized locality. The sources analyzed in this study confirm that physic gardens called jong-yakjeon(royal medicinal herb gardens) were in operation in the early Joseon dynasty when policies to investigate, discover, cultivate, and research native herbs were put into place. It is likely that the jong-yakjeon were established at the beginning of the Joseon dynasty as subsidiary facilities under its central medical institutions, the Naeuiwon and Hyeminseo, and then declined in the late Joseon dynasty. Jong-yakjeon can be confirmed to have existed in the mid-15th century. Physic gardens were located in several places outside the Fortress Wall of Hanyang, such as Yakhyeon, Yuldo, Yeoudo, and Saari. The total area encompassed by physic gardens was about 160,000 square meters in the early 18th century. In jong-yakjeon, dozens of medicinal herbs were cultivated, including Schizonepeta tenuifolia var. japonica, Rehmannia glutinosa, and Glycyrrhiza uralensis Fischer, and these gardens were operated by physicians dispatched from the Naeuiwon and dozens of provincial slaves. In conclusion, the jong-yakjeon were similar to the physic gardens of Renaissance medical universities in that they reflected the interest in and development of theories about new herbs, and were similar to the physic gardens of medieval castles and monasteries in terms of species types, location, and function. This paper has limitations in that it does not present the specific spatial forms of the yakpo or the jong-yakjeon. Nevertheless, this paper is significant for the field of garden history because it shows that physic gardens in Korea appeared in the late Goryeo and early Joseon dynasties concomitantly with the development of medicine towards native herbs and functioned as utilitarian gardens to cultivate community remedies.

Purpose and Method : We have many difficulty of using the existing medical Hurbs based on the theory of Yin-yang and the five elements, this is why we still do not explain the Sasang Constitutional medical Hurb Classification and do not have the Sasang Constitutional Pharmacology exactly, so we easily enter into a dispute and confusion. So through literary consideration about clematis mandshurica Maxim. I try to objectify Sasang Constitutional Clasification of Clematis mandshurica Maxim and the spirit of using Clematis mandshurica Maxim and common property of Sasang Constitutional Medical Hurb and try to find out a clue that search the effect of other Sasang Constitutional Medical Hurb. Result : Qi(氣) and mi(味) of Clematis mandshurica Maxim has bitter and hot taste and have won Qi(溫氣), the color is dark, the using portion of clematis mandshurica Maxim is root as medial Hurb. So Clematis mandshurica Maxim fall down from lung and divied impurity and purity and able to remove the symptom that dryness and fever is solidified like Magnoliae cortex(厚朴). Clematis mandshurica Maxim have the effect of awakening Jin-Qi(眞氣) of lung and divide impurity and purity of Qi(氣) and ack(液) and improve the fuction and structure of Taeumin(太陰人) I think that the method of literay consideration on objectification of Sasang Constitution Pharmacology is of great value.
