This paper intends to articulate concretely the contents and methods of Confucius self-cultivation and their practical characteristics through the analysis of S?nsan Wang Fuzhi (船山 王夫之, 1619~1692)'s On Reading Four Classics - Chungyong 讀四書大全說-中庸. The essence of the practical philosophy that penetrates Chungyong (中庸: The Doctrine of the Mean) is the practice of self-cultivation through Chonyang (存養: Preserving one's self) and $S{\breve{o}}ngchal$ (省察: Self-reflection). It can come down to two cultivation practices: 1) careful and discrete thinking without seeing or listening (Kyesingonggu: 戒愼恐懼), 2) solely looking into what is hidden and covert (Sindok: 愼獨). $S{\breve{o}}nsan$ grasped the importance of the two concepts for practical philosophy and articulated the principles of practical self-cultivation of Chungyong by paying attention to the differences and mutual-relations of the two concepts. Especially, he put the emphasis on the study through Chonyang and then focused on the relations between Chonyang and $S{\breve{o}}ngchal$. He consistently argued that the Kyesingonggu's Chonyang study was what enabled the Sindok's $S{\breve{o}}ngchal$ study and clarified the meanings of Chonyang in self-cultivation. Furthermore, he established the self-cultivation study of Chungyong as the primary self-cultivation theory of Confucianism by maximizing the practical characteristics within $Chonyangs{\breve{o}}ngchal$.

The importance of plant factory which blend agriculture and manufacture has been discussed widely. This company has researched hydroponics technique for cultivation which has been mainly developed in the sites of Okinawa and Hyougo Prefecture. In 1987, we stopped the previous research there, and started a new one far plant factory at the Agricultural Research Center of Chiba Prefecture. In 1989, we built four experimental plant factories (120㎡) at Chiba Oil Factory Refinery in Ichihara-city, developing techniques of cultivation, equipment production and environmental control for cultivation system of tomato, strawberry and leaf vegetables.

Artificial cultivation of Lyopyllun decastes is costly because the high expense is required for soil covering and bark. Therefore, most farmers of Lyopyllun decastes have recognized it is difficult to cultivate it. The purpose of this study is to reduce the cost of cultivation of Lyopyllun decastes by applying new cultivation method and introducing mutation of fungi. In this study, a new method of practical artificial cultivation was developed through many experiments using fermented pine sawdust and wheat bran. In conclusion, the method of practical artificial cultivation of Lyopyllun decaste is simple and cost efficient because neither soil covering nor bark is required.

The optimal log conditions of cultivation are as follows. 1) Log-length, 100~120cm 2) Hole-depth, 1~1.5cm 3) It takes 55~67 days for primodia induction is possible to harvest fruiting bodies for 6~7 months. Meanwhile, the total of 10 species pest including Trichoderma sp. occurred during the cultivation.

Anthracnose, caused by Colletotrichum gloeosporioides (C. gloeosporioides; Teleomorph: Glomerella cingulata), is the most destructive disease that affects sweet persimmon production worldwide. However, the biology, ecology, and genetic variations of C. gloeosporioides remain largely unknown. Therefore, in this study, the development of fungicide resistance and genetic diversity among an anthracnose pathogen population with different geographical origins and the exposure of this population to different cultivation strategies were investigated. A total of 150 pathogen isolates were tested in fungicide sensitivity assays. Five of the tested fungicides suppressed mycelial pathogen growth effectively. However, there were significant differences in the sensitivities exhibited by the pathogen isolates examined. Interestingly, the isolates obtained from practical management orchards versus organic cultivation orchards showed no differences in sensitivity to the same fungicide. PCR-restriction fragment length polymorphism (RFLP) analyses were performed to detect internal transcribed spacer regions and the ${\beta}$-tubulin and glutamine synthetase genes of the pathogens examined. Both the glutamine synthetase and ${\beta}$-tubulin genes contained a complex set of polymorphisms. Based on these results, the pathogens isolated from organic cultivation orchards were found to have more diversity than the isolates obtained from the practical management orchards.

This study was carried to analyze the demonstrational cultivation process of selenium supplemented P. linteus and G. lucidum from 2005 to 2006 and ifs effect at Hochimin Agricultural Technology College(HATC) in Vietnam, according to the mutual contract between the Yunjung-nongwon, a fanning company in Korea and HATC. As a result of the demonstrational cultivation of selenium supplemented P. linteus and G. lucidum, the external aspect, such as size, thickness and color of the P. linteus and G. lucidum were very much high qualified comparing to the same strain P. linteus and G. lucidum generally cultivated in Korea. The major contribution factors to this high qualified mushroom product could be drawn as followings; keeping growing condition of the mushroom with precise data collection of Vietnam climate and weather, involvement of the various professors of Korea National Agricultural College(KNAC), maintenance of bio-technical security through the strain cultivation on the oak log in Korea, the Yunjung-nongwon manager's endeavor being consulted by the various professors of KNAC even to be a student of the agricultural chief executive officer(CEO) training course in KNAC and the HATC's constant cooperation to the mushroom demonstrational cultivation instead of the orchid which was originally contracted item.

This study was conducted to develop the hanging type circular-patterned system that at maximizing the spatial efficiency of strawberry cultivation to increase yields, while also reducing labor and improving energy efficiency. The system consists of a cultivation bed units, longitudinal moving device, bed lifting device, front and rear transfer devices, lateral transfer device, nutrient supply device, and control unit. Performance testing revealed that the operational motor for longitudinal movement should have a torque of at least 0.1Nm based on the design weight and traction force of the cultivation bed unit. The power consumption required to move one cycle was calculated to be approximately 149Wh when performing harvesting or maintenance tasks for all 10 cultivation beds. Vibration angles measured during bed movement showed that the lateral transfer resulted in a roll angle ranging from -0.62° to 0.68° and a pitch angle ranging from -3.79° to 5.26°. For longitudinal transfer, the roll angle ranged from -3.37° to 3.36°, and the pitch angle ranged from -0.45° to 0.49°.
