  • This study was undertaken to evaluate the automatic decision-making on the grading of 6-year-old fresh ginseng (Panax ginseng C.A. Meyer) by an image analyzer. The best input method for the 6-year-old fresh ginseng was under condition of a low resolution (128u 128 pixel) and illumination direction from bottom to up (light box). It was possible to identify the main root, lateral root, and rhizome of fresh ginseng by application of OPEN process in a function of an image analyzer. Finally, we developed the grade decision-making programs, GinP-1. The fitness rates for the fresh ginseng standards which were classified by experts were 94.6, 80.6, 81.5, and 100.0% for 1st, 2nd, 3rd, and 4th grade of fresh ginseng, respectively, and the total time of decision-making was about 4.3 seconds per one root. The decision-making time was reduced to 0.8 seconds per one root by enhancemeat of the Image analyzer, which was tested by the technical company of the image analyzer,'Carl Zeiss (Germany). As a result of this study, the automatic decision-making on the grade of fresh gin send by image analyzer seems to have high possibility.

  • To demonstrate the desalination system, the demo-plant was scheduled to be installed. The system was planned to use solar thermal collector as heat source and PV as electricity source. For the design of the desalination demonstration system, firstly the solar thermal system would be well designed from the result between the supplied heat into the fresh water generator and the fresh water yield. The generator for demonstration system was chosen as the fresh water generator of the single stage and effect with plate-type heat exchanger using low pressure evaporation method. The test facility for the tests to reveal the relationship between the fresh water yield and the supplied heat flow rate was designed and manufactured. The maximum fresh water yield of two fresh water generators applied in this study was designed as 1.5 Ton/day. The parameters relating with the performance of fresh water generator are known as sea water inlet temperature, hot water inlet temperature, and hot water flow rate. Through the experiments, this study firstly showed detail operation characteristics of the generator and designed the solar thermal system for the demonstration system.

  • The effect of cryopreservation on extracellular matrix was studied with the ultimate objective of permiting a prediction of the tendency of aorta conduit tissue to calcify following transplantation. Cryopreserved and fresh porcine aorta conduit tissues were extracted using guanidine-hydrochloride (Gdn-HCl) followed by sequential digestion of the tissues with collagenase, elastase, and papain. Glycosaminoglycans (GAGs) of the proteoglycans (PGs) were isolated and quantitated. Gdn-HCl extracted about 61% and 62% of the total GAG (proteoqlycan) material from cryopreserved and fresh tissues, respectively. Collagenasesolubilized proteoglycans from Gdn-HCl extracted tissue represented 20% and 13%, respectively, of the total GAGs present in cryopreserved and fresh tissues. Subsequent elastase hydrolysis of collagenase-digested tissue released about 11% of total GAGs from cryopreserved tissue and 16% from fresh tissue. The remaining 8%, from cryopreserved tissue, and 9%, from fresh tissue, of the total GAGs were obtained after using a papain hydrolysis. There was essentially no difference between fresh and cryopreserved tissues in the relative distribution of proteoglycans in the extracts and digestions except in the initial digestion step where more proteoglycans were obtained from collagenase solubilization of cryopreserved tissue than fresh tissue (p<0.05). The histologic status of the fresh and cryopreserved porcine aortic conduit did not differ markedly. The normal tissue architecture was not affected markedly by the cryopreservation procedure as neither alteration of elastic structure, fibrous proteins nor alteration of nuclear distribution or smooth muscle cell morphology was detected. Quantitative tissue mineral studies revealed that the mean calcium content of the cryopreserved aorta conduit tissue $(165{\pm}3\;{\mu}g/g\;wet\;tissue)$ was higher than that of the fresh tissue $(105{\pm}4\;{\mu}g/g\;wet\;tissue)$ $(p<0.05)$. The mean phosphorus content was $703{\pm}35\;{\mu}g$ wet tissue from cryopreserved tissue and $720{\pm}26\;{\mu}g$ wet tissue from fresh tissue. The study indicates that there is no significant alteration in the distribution of PGs in properly cryopreserved tissue, but the total calcium level appears to be increased in tissue cryopreserved by the cryopreservation process used in this study.

  • To maintain flavor and color of fresh green pepper, the fresh green pepper paste was directly prepared from fresh green pepper. The characteristic of fresh green pepper paste and processing properties were investigated, and the effect of salt, glucose, acid and heat on product quality during processing and storage were studied. After the processed fresh green pepper paste was stored at 3$0^{\circ}C$ and 5$^{\circ}C$ without light for 6 months. The weight and pH of pericarp were 86% of total and 4.5~5.0, respectively. Addition of 10% salt, 5% glucose, and 0.1 dl-malic acid to the fresh green pepper paste maintain flavor of fresh green pepper could be preserved for 6 months at 5$^{\circ}C$. Panel test showed fresh green pepper paste which was made of 10% salt, 5% glucose and 0.1% dl-malic acid to the fresh green pepper was quite acceptable.

  • Water turnover and consumption of steers fed either fresh cut grass or hay and water turnover of steers grazed in summer or in fall were determined using 18 Holstein steers weighing 226 to 382 kg. Steers consumed 7.0 or 7.5 kg of dry-matter from hay or fresh cut grass. Animals fed hay drank significantly more water than those given fresh cut grass (P<0.01). Total water consumption, however, was greater in steers fed fresh cut grass than those given hay (P<0.05). Water turnover was about the same as total water consumption with a tendency for slightly higher values in water turnover irrespective of feeding regimes. Steers grazed in summer had greater water turnover than those grazed in fall. Water turnover was about the same in steers fed fresh cut grass and grazed in summer but decreased in steers on the dry ration or grazing in a cool season of the year.

  • A fresh water generation system is designed for converting brackish water or seawater into fresh water. In this paper fresh water generation by distillation process that evaporates feed water and subsequently condenses vapor as evaporation product to get fresh water was studied and city water was employed as feed water. The system uses the ejector to create a vacuum, under which liquid can be evaporated at lower temperature than it at normal or atmospheric condition, hence less energy consumption. The effect of various operating conditions i.e. temperature of feed water and different orifice diameters were studied experimentally to investigate the characteristic of the system. It was found that these parameters have significant effect in the performance of fresh water generation system with low pressure evaporation.

  • Among many kinds of constituents of ginseng root, starch was the most noticeable component related to inside white in fresh ginseng. The ash of inside white section was higher in content and greenish gray in color. The water binding capacity and ash content of the starch from inside white fresh ginseng were higher than those of starch from normal fresh ginseng, but amylase content was not significantly different. Ash of inside white fresh ginseng starch contained higher in Ca, Mn and Fe content. Complexes of small granular starch and amino acids were rich in swelling power, and solubility by temperature change were similar between inside white fresh ginseng starch and normal one, but the former was more easily swelled than the latter.

  • Volatile flavor components of fresh ginseng (Panax ginseng C.A. Meyer.) were studied. Steam distillate of fresh ginseng was extracted with ethyl ether and the extract was separated into four fraction: neutral, phenolic, acidic and basis fractions. The ethyl ether concentrates and neutral fraction were analyzed by a combination of SE-54 fused silica capillary gas chromatography and mass spectrometry. Major flavor components of fresh ginseng were predominantly mono(n +2) and sesquiterpenes(n +3) in over two hundred constituents. Of these, 28 were newly identified in volatile flavor components of fresh ginseng by GC-MS.
