Although vegetable oils provide good lubricity, they still need optimization by certain additive technology for practical applications. ZDTP improve antiwear properties of vegetable oils. However the additive performance depends on quality of the base Oil. Antioxidants were applied to prevent the auto-oxidation of vegetable oils. Good synergistic effect of anti-wear and antioxidant additives was confirmed.

Worldwide consumption of vegetable soybean has been increasing recently, but in the process of vegetable soybean production, threshing and separation work accounts fur about $80\%$ of overall labor. Therefore, developing of the vegetable soybean thresher is necessary to reduce the cost of labor. The main objective of this study is to acquire the basic in-formations for design of the vegetable soybean thresher which is suitable for domestic circumstances. We made the experimental system to investigate the threshing and separating performance at the several speeds of threshing cylinder and separating blower according to the kinds of threshing tooth. The result are as follows; Threshing performance of vegetable soybean thresher was shown as the best in case the threshing tooth made of rubber which has the 80 of Shore hardness was used at the circumference speed of cylinder of 5.8$\~$8.1m/s. Also separating cleaning performance of vegetable soybean thresher was shown as the best at more than 1,300 rpm of blower speed and $60\~80\%$ of opening ratio of suction port.

The purpose of this study was to evaluate the daily vegetable and fruit intake status of Korean adults and to examine the relationship of vegetable and fruit intake with bone metabolism. The vegetable and fruit intake of 542 healthy male and female adults was analyzed. Then, by selecting 51 targets from the subjects, the relation of vegetable and fruit intake with serum calcium, osteocalcin and deoxypyridinoline (DPD) excretion in urine was examined. The total vegetable intake per day was 397.7 g and 333.5 g by men and women respectively for the age group of 20-29, 366.9 g and 309.2 g respectively for the age group of 30-49, 378.4 g and 325.9 g respectively for the age group of 50-64. Of vegetable varieties, leafy and stem vegetables displayed the highest intake. The order of major intake items of vegetables and fruits was found to be Chinese cabbage kimchi, onion, radish, cucumber, and welsh onion for the age group of 20-29, watermelon, Chinese cabbage kimchi, peach, potato, and onion for the age group of 30-49 and watermelon, Chinese cabbage kimchi, tomato, potato, and peach for the age group of 50-64. Of 51 targets, ${\beta}$-carotene intake displayed a significantly negative correlation with serum osteocalcin. While caloric intake as well as protein, carbohydrate, calcium, phosphorous, zinc and total food intake displayed a significantly negative correlation with DPD excretion in urine, tuber vegetable intake displayed a significantly positive correlation with DPD excretion in urine. In the future, a study will be necessary to accurately explain the relevance of vegetable and fruit intake with bone mineral density and bone metabolism. Also, efforts will be required to increase vegetable and fruit intake.

Object : To investigate which diseases the utilization of various vegetable oils were used and how they were used for treatment, and to change and develop vegetable oil combined prescriptions so that the Korean medical treatment effect in clinical practice can be enhanced. Methods : All words containing oil(油) were searched and selected oils used for simple prescription and oil combined prescription. Aii of animal oils such as butter(酥油), Suis oil(猪油), Anceris oil(鴈油), and Actonis caro oil(猯油) were excludIt is suggested to develop a new formulation by succeeding the utilization methods of various effects of sesame oil and other vegetable oils.ed. All selected oils were classified as sesame oil(麻油)(inclusive, 脂麻油, 胡麻油, 香油, 淸油) or other vegetable oils. Result : 1. In 『Donguibogam』(『東醫寶鑑』), 14 other vegetable oils were used to 23 prescriptions. 2. Sesame oil was used to 187 prescriptions over 41 disease categories as of 20 effects described in the 『Zhenghebencao』(『政和本草』). 3. In 28 prescriptions, sesame oil was also used for hygiene and prevention, emetic, preparating herbs and so on. Conclusion : The 101 prescriptions used for medicinal auxiliary materials are due to the efficacy of treatments of malignant furuncles, sores, scabies, promoting regeneration of tissue and flesh, reliving pain, dispersing abscess and swelling and supplementing fissured skin. In 『Donguibogam』(『東醫寶鑑』), the unique efficacy of each vegetable oil and sesame oil was used in various ways and preparation forms to treat various diseases. It is suggested to develop a new formulation by succeeding the utilization methods of various effects of sesame oil and other vegetable oils.

Vegetable seeds are one of the most important key factors to determine the way of vegetable's production, distribution, processing and storage. Unfortunately, because of international exchange crisis in 1997, the most of main Korean seed companies were merged into foreign capitals. Currently, many domestic seed companies are incapable of their own survey and development of vegetable seed markets in foreign countries. To provide valuable seed market information for these companies, China, especially Yunnan and Guangdong provinces in China, was selected. Since China is one of the major vegetable seed importers. Also, Yunnan and Guangdong provinces are the most promising targets to export Korean vegetable seeds. The current status of vegetable production in China was analyzed with consideration of Yunnan and Guangdong provinces. The contents of survey and analysis are covering major vegetable crops' cultivation area, farm number, cultivation type, production amount, market price, farm income, packaging method, distribution type and amount of seed consumption. And particularly, major horticultural characteristics of leading varieties were presented to assist the development of exportable varieties of domestic seed companies. We assume the results of this study would be practically usable for the development of exportable varieties.
