  • This study was Carried out to the changes of nutrientd and components for food valuation estimation during maturation of Elaeagnus multiflora fruits. The content of moisture was decreased during maturation, but brix was increased. The content of carbohydrate was increased during maturations but crude protein was decreased. And the content of reducing sugar was increased. The content of free fructose and glucose were high and its content were increased during maturation. Total content of free sugars were 135.66 mg/100 g-fr.wt in mature green fruit, 544.26, 787.83 mg/100 g-fr,wt in mature and over mature fruits, respectively. The Organic acids of Elaeagnus multiflora fruits were acetic, citric lactic, and malic, succinic acids. The content of citric acid was the highest among organic acids. Total content of organic acids were 407.95 mg/100 g-fr,wt in green mature fruits, and were decreased during maturation. The content of reducing vitamin C was 56.98 mg/100 g-fr.wt in mature green fruits and total contents of vitamin C was decreased during maturation. The content of phenol substance was 411.39 mg/100 g-fr.wt in the mature green fruit and was decreased during maturation.

  • In order to determine if the mRNA and protein expression levels of 3T3-L1 adipocytes are influenced by oriental medicines, adipocytes were treated with $100\;{\mu}g/ml$ of G-Re and aqueous extract of a Coix lachrymajobi var. mayuen (AEC) every other day for 12 days, respectively. The tumor necrosis factor alpha ($TNF-{\alpha}$). mRNA and protein expressions were suppressed markedly in treated mature adipocytes. Those of lipoprotein lipase (LPL) levels were found to increase gradually in preadipocytes differentiating into mature adipocytes. Those were higher than that of the untreated mature adipocytes. The treated adipocytes showed reduction of leptin expression levels, while in untreated mature adipocytes cell, those of levels were significantly higher after the conversion of preadipocytes into mature adipocytes. The resistin levels in the treated adipocytes were significantly decreased comparing to that of the untreated mature adipocytes. In conclusion, the expression levels of LPL, $TNF-{\alpha}$, leptin and resistin mRNA and proteins are shown to be regulated by G-Re and AEC, making them potential candidates for controlling fat mass related obesity.

  • The changes of selenium and zine contents of transitional milk and mature milk at 7 and 60 days postpartum were comparatively studied on 20 Korean lactating women. the selenium and zinc contents of transitional milk and mature milk were analyzed by atomic absorption spectrophotometer after wet-digestion. The mean selenium contents wer 12.2$\mu\textrm{g}$ /ι and 11.5$\mu\textrm{g}$/ι at 7 and 60 days postpartum, respectively. The mean zinc contents decreased significantly from 4.23mg/ι at 7 days to 1.62mg/ι at 60 days postpartum (p<0.05).

  • Fibre to the home (FTTH) in KOREA has grown rapidly in recent years. The number of FTTH subscribers exceeded 6.6 millions by end of DEC 2008. It seems that FTTH has moved from the initial, the growth stage to the mature stage. Some design techniques have been developed in order to construct the access network effectively for the mature stage. This paper deal with design, construction and maintenance of optical fibre access networks immediately, effectively and economically.

  • In this paper, we consider a delay differential equation model of two competing species with harvesting of the mature and immature members of each species. The time delay in the model represents the time from birth to maturity of that species, which appears in the adults recruitment terms. We study the dynamics of our model analytically and we present results on positivity and boundedness of the solution, conditions for the existence and globally asymptotically stable of equilibria, a threshold of harvesting, and the optimal harvesting of the mature populations of each species.

  • Experiments were conducted to study the effect of IBA, mineral stone and stem hardness on rooting characteristics in mature Aloe vera plant. The rooting ability in matured Aloe vera was of highly significance when the amount of IBA treatment was increased to 5.000mg/l. The treatment of IBA 5.000mg/l, together with mineral stone(v/w 1.5 times), gave more root number, the length and the dry weight of root were, also, higher in semihard wood cutting than soft wood cutting in matured Aloe vera.

  • A mature mutant ribose binding protein (RBP) of Escherichia coli was obtained by site-directed mutagenesis, replacing Thr-3 in the N-domain of wild-type mature RBP (WT -mRBP) with a Trp residue (N- Trp-mRBP). The equilibrium unfolding properties and the refolding kinetics of this protein were monitored by fluorescence and circular dichroism (CD). (omitted)

  • Lipomas is one of the most common benign neoplasm in the body, but only rarely occurs in the oral cavity We report here a case of a 49-year-old female with a lipoma of palatine tonsil. Microscopical examination revealed a stromal neoplasm composed of mature fat with the presence of a few thin and anastomosing fibrous septa. The surface epithelium was of nonkeratinizing stratified squamous type. There was the dense fibrous connective tissue between mature fat and surface epithelium. The histopathologic findings and literature on tonsillar lipoma is reviewed.

  • The changes of contents of organic acids in flue-cured tobacco leaves depending on stalk position and maturity viz immature, mature and overmature were studied in 1982-83. Among them, particularly, the leaves harvested at mature stage have the lowest amounts of oxalic and citric acids in smoking or cutter leaves but the acid contents has increased during the overmature. The linolenic acid content tended to be lower with increase of maturity.

  • Steers (n=335) of known genetic backgrounds from four fundamentally different growth types were subjected to two production systems to study differences in carcass traits. Growth types were animals with genetic potential for large mature weight-late maturing, intermediate mature weight-late maturing, intermediate mature weight-early maturing and small mature weight-early maturing. Each year, in a nine-year study, calves of each growth type were weaned and five steers of each growth type were developed on pasture or feedlot and slaughtered at approximately 20 and 14 months of age, respectively. Data collected were pre-slaughter shrunk body weight (SBW); hot carcass weight (HCW); dressing percentage (DRESS); fat thickness at the $12^{th}$ and $13^{th}$ rib interface (FAT); percentage kidney, pelvic, and heart fat (KPH); longissimus muscle area (LMA); marbling score (MARB); quality grade (QG); and yield grade (YG). Year and growth type were significant for all carcass traits. The growth type${\times}$production system interaction was an important source of variation in SBW, HCW; FAT, YG and MARB. The same interaction was non-significant for DRESS, KPH, LMA and QG. Carcass differences in measures of fatness were greater in the feedlot system than in the pasture system. These data could aid producers in matching beef growth type to the production system most suitable for efficient use of resources.
