The proximate composition, and the levels of total phenols, phenolic acids, and DPPH radical scavenging activity in Cheongdobansi persimmon fruits assayed during development (from July to October), were investigated. All of moisture, crude protein and crude fiber contents decreased as picking time was delayed, however, crude fat content rose. Crude fiber content increased after September. Total phenol content tended to fall during development. The principal phenolic acids were chlorogenic acid, caffeic acid, p-coumaric acid and salicylic acid; the level of each phenolic acid tended to decrease during development. DPPH radical scavenging activity fell as picking time was delayed. Thus, harvest time influenced the levels of chemical components and the antioxidative properties of persimmon fruit. It follows that unripe fruit may be utilized as a raw material yielding many useful products.

Purposes: This study was to validate the Robotic Smart Work System that can provides better working conditions and high productivity in unstructured environments like bio-industry, based on a tele-operation system for fruit harvesting with low cost 3-D positioning system on the laboratory level. Methods: For the Robotic Smart Work System for fruit harvesting and cultivation management in agriculture, a vision based tele-operating system and 3-D position information are key elements. This study proposed Robotic Smart Farming, an agricultural version of Robotic Smart Work System, and validated a 3-D position information system with a low cost omni camera and a laser marker system in the lab environment in order to get a vision based tele-operating system and 3-D position information. Results: The tasks like harvesting of the fixed target and cultivation management were accomplished even if there was a short time delay (30 ms ~ 100 ms). Although automatic conveyor works requiring accurate timing and positioning yield high productivity, the tele-operation with user's intuition will be more efficient in unstructured environments which require target selection and judgment. Conclusions: This system increased work efficiency and stability by considering ancillary intelligence as well as user's experience and knowhow. In addition, senior and female workers will operate the system easily because it can reduce labor and minimized user fatigue.

Objectives: The objective of this study was to explore the anti-obesity effect of Cydonia oblonga Miller fruit extract (COME) and to compare its anti-obesity efficacy with Garcinia cambogia extract (GCE) in diet-induced obese mice. Methods: Five-week-old male C57BL/6 were allocated into four groups: control diet (CD), high-fat diet (HFD), HFD + 400 mg/kg body weight (BW)/day COME (H+C), or HFD + 400 mg/kg BW/day GCE (H+G) groups. COME or GCE was administered once a day by oral gavage for eight weeks. Body weight, body fat percentage, fat weight, and biochemical parameters in serum were measured. The expressions of transcription factors and their target genes in epididymal adipose tissues were analyzed by reverse transcription polymerase chain reaction. Results: COME reduced body weight, weight gain, body fat percentage, total white adipose tissue weight, adipocyte size, and serum levels of insulin and leptin in high-fat diet-induced obese C57BL/6 mice. COME suppressed the mRNA expressions of CCAAT/enhancer binding proteinα, peroxisome proliferator-activated receptorγ, sterol-regulatory element-binding protein-1c, fatty acid synthase, and adipocyte protein 2 and increased carnitine palmitoyl transferase 1 mRNA expression in epidydimal adipose tissues. The anti-obesity efficacy of COME was found to be similar to that of GCE at the same dose. However, COME more effectively decreased adipose tissue weights, epididymal adipocyte size, serum insulin and leptin compared to GCE. Conclusions: These results demonstrated that COME is not toxic and exhibits anti-obesity efficacy at a level similar to that of GCE, suggesting that COME may be applicable as an anti-obesity agent.

The demand of environmental friendly packaging materials such as pulp mold has been increased. The application of the oil palm biomass, EFB (Empty Fruit Bunch) fiber as natural raw materials to the pulp mold could increase the usability of the pulp mold by the reduced production cost brought from the relatively low cost of EFB. The effects of the EFB(Empty Fruit Bunch) fibers on the properties of pulp mold and on the process efficiency were evaluated in this study. The pulp mold samples were prepared with mixture ONP (Old news paper) and EFB by using laboratory wet pulp molder. The changes in the drying efficiency were measured with the changes in the solid contents of pulp mold samples during drying process. The efficiency of the surface coating treatment on the pulp mold depending on the condition of the pulp mold samples were also evaluated in order to improve the water resistance properties of pulp mold. The addition of EFB increased the drying efficiency by providing the bulkier structure and the higher water contact angle, which indicated the better water resistance properties. The water resistance were improved by the surface coating treatments and the application of surface coating on the pulp mold at the higher moisture contents resulted in the higher improvement in the water resistance. The bulkier structure originated from the application of EFB fiber reduced the effects of the surface coating, which could be overcome by the control of surface coating process.

Organosolv ethanolamine pulping for oil palm empty fruit bunches(EFB) were evaluated in this study. The screen yield by the ethanolamine pulping were higher than that by the soda pulping at the same operation conditions. The higher concentration of ethanolamine solvent resulted in the higher yield and the lower contents of residual lignin. The EFB pulp fibers were the narrower in fiber width but the higher in coarseness than those of the hardwood pulp fiber, while the fiber length of the EFB pulp fiber were similar to that of the hardwood fiber. The intrinsic zero span tensile testing showed the EFB pulp fiber by the 80% ethanolamine pulping were the stronger than the fiber by the soda pulping. The results of this study supported that the ethanolamine pulping could be used as an alternative pulping method for the EFB.
