  • During handling unitized products, they are subjected to a variety environmental hazards. Shock and vibration hazards are generally considered the most damaging of the environmental hazards on a product, and it may encounter while passing through the distribution environment. A major cause of shock damage to products is drops during manual handling. The increasing use of unitization on pallets has been resulted in a reduction in the manual handling of products and with it a reduction in the shock hazards. This has caused and increasing interest in research focused on vibration caused damage. the use of pallets as a base for unitizing loads, aids in the mechanical handling, transportation and storage of products. Besides aiding in the handling, transportation and storage of products, a pallet also acts on and interface between the packaged goods and the distribution environment. The determination of the impact deformation of the cushioning materials such as tray cup (polymeric foam) and corrugated fiberboard pad must be carried out to design the proper packaging system providing adequate protection for the fruit, and to understand the complex interaction between the components of fruit when they relate to expected transportation vibration inputs. In this study, the theoretical analysis of impact deformation for cushioning materials by dynamic vibration. The impact deformations of SW and DW corrugated fiberboard pad in acceleration amplitudes of 0.25 G-rms and 0.5 G-rms that were usually generated in transport vehicles during distribution environments were very small compare with the thickness of corrugated fiberboard pad. The maximum of vibration acceleration level of tray cup by vibration impact was about 3.2 G-rms. The theoretical allowable acceleration (G-factor) of the pear was 0.7102 G-rms, and the maximum dynamic deformation estimated within G-factor was about 1 mm.

  • Interspecific fusion products were obtained from fusion of Ganoderma applanatum and Ganoderma luridum. Frequency of fusion was 0.77-1.38%. Fusion products were selected by the comparision of morphology and color of colony. Fusion Products had chracteristics of two parental strains and generally grew faster than the parents. Some fusants were segregated on GCM. Fusion products were confirmed by mycelial morphology and electrophoretics pattern of esterase isozyme from mycelium. Most of fusion products were lack in clamp connection but those fusion products, that were segregated produced mycelium with and without clamp connection. Some of the fusion products produced fruit body on sawdust medium.

  • The objective of this study was to determine current consumer awareness of Omija (Schizandra chinensis Bailon) fruit in order to develop ready-to-drink (RTD) Omija-flavored beverages using qualitative consumer analysis. A series of four different focus group interview sessions were conducted using carefully chosen consumers with specific demographics, and each group involved eight respondents. Consumer's qualitative reactions regarding Omija fruit, Omija extract products, ready-to-drink beverages and Omija-flavored RTD beverages were explored. Distinct differences in consumer awareness and consumption patterns of Omija extract and RTD beverages were observed between consumers in their 20s and consumers in their 30s to 50s. The expected sensory characteristics of Omija-flavored RTD beverages were also different based on participants' age. Findings from the current study can aid product developers utilizing Omija fruit by providing valuable insights into current consumer behavior and consumer awareness regarding Omija.

  • Selection of superior phenotypes of fruit trees and products based on established criteria by local people is a prerequisite for future species domestication and conservation. Thus the study objective was to identify the local people's perceptions and preferences on baobab trees and products. A sample of 142 respondents was randomly selected using structured interviews in Blue Nile and North Kordofan, Sudan in 2013. Descriptive analysis was employed using SPSS and Excel programs. The study results indicated that local people use the morphological characteristics of the tree (leaves, fruits, seeds, kernels and bark) to differentiate individual trees. Based on the perceptions, local people recorded trees with delicious leaves, white pulp color, big fruit size and mature capsule size, and high pulp yield as criteria for differentiating between baobab trees in the study areas. In contrast, the undesirable traits were connected to trees with acidic pulp, slimy pulp, bitter leaves, and low pulp yield. The study concluded that the ethnobotanical knowledge of the baobab tree and its products may play an important role in tree domestication and improvement in Sudan. However, further research on tree genetics is needed to complement the ethnobotanical knowledge for baobab resources domestication and conservation.

  • This experiment was executed to investigate the effect of the carpenter bee as a pollinator on the fruit set increment of sweet pepper in summer hydroponics in the alpine area of Gangwon province, Korea. Where the number of fruit sets were increasing during the treatment of pollination by the carpenter bee, total yields during the whole growing period were not different. The number of seeds per fruit in the treatment of the carpenter bee increased more than that in the control by 7.3 percent increment, but the percentage of blossom-end rot increased. As fruit weight range of SS size (below 120g) decreased and that of L size (from 181g to 210g) increased by the pollination treatment, so the percentage of standardized products for the export to Japan improved. Therefore this result was effective for the fruit production of high quality for the export to Japan and it will be necessary for further study on the method of reducing blossom-end rot to be done.

  • Background: Hair loss related syndromes are increasing due to environmental pollution and stress. Hair care products are mainly prepared by mixing chemicals and natural extracts, such as those obtained from medicinal plants. The purpose of this study was to investigate the effects of 70% ethanol extracts from the flowers of Calendula officinalis, fruit body of Phellinus linteus, and the whole plant of Houttuynia cordata on the growth of CCD-986 cells, hair follicle dermal papilla cells (HFDPC), and 3T3-L1 cells. Methods and Results: All sample extracts at all concentrations, except for that from P. linteus fruit body at $500{\mu}g/m{\ell}$, were cytotoxic to CCD-986 cells. However, none of the sample extracts were cytotoxic to HFDPC. The lipid differentiation of 3T3-L1 cells regulates hair regeneration via secretion of platelet derived growth factor. The 70% ethanol extract of H. cordata whole plant promoted hair growth. Adipogenesis rate significantly increased in a treatment concentration-dependent manner. Conclusions: These results suggest that 70% ethanol extracts of C. officinalis flower, P. linteus fruit body and H. cordata could be used for the development of hair care products.
