  • The application of fertilizer P to Desmodium intortum at 40, 60 and 100 kg/ha resulted in the P content of the legume regrowth being 0.10, 0.13 and 0.16% on a dry matter basis. When the forages were fed alone to sheep in metabolism pens the corresponding voluntary intakes by sheep of the three forages were 27.3, 42.7 and $54.3g/W_{kg}{^{0.75}}$, respectively. Provision of additional P by rapid infusion into the rumen each morning before any fresh food was offered depressed the voluntary intake of all three feeds. It is suggested that the adverse effect of supplementary P was probably caused by an induced deficiency of either Ca or Mg and led to a reduction in microbial activity in the rumen.

  • Recently, Fine Ceramics have been concerned significantly with some excellent properties and many functions as new industrial materials to the industry at alrge. For the manufacture of Fine Ceramics, sintering is essential process. Thus the most of a Fine Ceramics used for precision parts are in need of machining proces. It is, however, very difficult to manufacture the Advanced Ceramics with high efficiency because they have not only high strength and brittl- eness but also high hardness. In present research, experiments are carried out to obtain the basic knowledge of Fine Ceramics grinding with high efficiency. Representative advanced ceramics, such as A1/sub 2/0/sub 3/, Z/sub r/O/sub 2/SiC snd Si/sub 2/N/sub 4/are ground with diamond wheels using conventional surface grinding machine. This research is carried out for the purpose of saving machining technology required for manufactiring Fine Ceramics parts

  • We present the results of the survey for submillimeter galaxies in the MS0451 (04h 54m 10.8s, -03d 00m 57.0s) at z = 0.55 and PKS1138-262 (11h 40m 48.25s, -26d 29m 10.1s) at z = 2.16 with the 1.1mm bolometer array AzTEC at the James Clerk Maxwell Telescope. The samples were centered on a prominent large-scale structure overdensity. Submillimeter galaxies seem to be starburst galaxies at high redshift ($z\;\geq\;1$) with high starformation rates ($\sim1000M\odot\;yr^{-1}$) or active galactic nuclei (AGN). We have obtained AzTEC images using the AzTEC data reduction pipeline with the IDL language. Through a bayes' theorem, we determined the extragalaxy catalogue, containing the false-detection rate, completeness, flux deboosting correction, and the source positional uncertainty in this region. We compared the catalogue with HST, DSS, 2MASS observations.

  • The current study was conducted to identify relationship between myosin heavy chain I to objective color dimensions. Myosin heavy chain I isoform showed coefficients of determinant($r^2$) of 0.54 and 0.40 for Hunter a* and b* values. For he current dataset, Hunter a* value at day 1 had higher relationships with that at both day 7 and 14, emphasizing the importance of initial meat color which is largely affected by animal management prior to slaughter.

  • The optimal conditions for the protoplast isolation from the leaves of pea (Pisum sativum L. cv. Sparkle) and barley (Hordeum vulgare L. cv. Baecdong) were determined in order to achieve a somatic hybridization between two species. It was revealed that the use of 0.5M sorbitol as an osmoticum was appropriate for pea. The yield of intact protoplasts was the highest (40%) when pea leaves were incubated in the enzyme solution for 4 hours. In case of barley, the optimal concentrations of cellulase, pectinase and mannitol as the enzyme solution were 2%, 1% and 0.35M, respectively. And the yield of barley protoplasts was the highest(87%) when leaves were incubated in this enzyme solution for 3.5 hours. A fusion of protoplasts from pea and barley was induced by PEG treatment enriched with calcium salts within 60 minutes.

  • The purpose of this study is to characterize body types of males in their twenties, and to provide information on body types of males by classifying them into groups. In addition, this study attempts to provide ways that can help improve the fit and coverage rate of ready-to-wear clothes by developing an apparel sizing system according to body types. 297 male subjects in their twenties participated in this study. 54 anthropometric and 35 photographic measurements were taken from each subject. After combining the body types of the front and the side into a whole body, we selected typical body types out of the combinations. It is shown that 84.64% of males in their twenties belong to the HI type, H/equation omitted/ type, X/equation omitted/ type, Xl type, Yl type, and HS type. To develop a new size system of clothes, the distribution of sizes was determined by using means and standard deviations for basic parts of each body type. Then, the most optimal sizes were selected separately for each body type to maximize the coverage rate.

  • From persimmon fruits, about 40 yeast strains were isolated and tested for their ability of alcohol fermentation were tested. Among them, two strains, RCY14 and RCY15, showing the highest alcohol fermentibility were selected for further investigations. They were identified as Saccharomyces cerevisiae and Saccharomyces kluyveri based on their morphological, cultural and physiological properties. Their optimum condition for the alcohol fermentation in YPD-15% glucose was pH 6.0, 30$circ$C and 120 rpm of shaking speed. The alcohol yields of S. cerevisiae RCY14 and S. kluyveri RCY15 in a persimmon juice were 94.54 and 96.81%, respectively. Although the alcohol yields of both strains were not very high in YPD-15% glucose, they were much higher in a persimmon juice as compared to those of S. cerevisiae Balyon-1, S. cerevisiae 701 and S. cerevisiaein W3 which are being used in the industrial alcohol fermentation.

  • Amid the booming research on new and renewable energy, the photovoltaic(PV) industry has been growing around the PV advanced countries such as Japan, Germany, Europe and USA. In recent years, China became a strong performer in the world PV market share, increasing solar cell production rapidly. Both world solar cell and module production and installation rose steadily in 2006 like recent bumper years. In 2006, the PV industry produced 2.54GW, representing growth of 40percent over the previous year, and the installations reached a record high of 1,744MW.

  • With a view to providing the basic data of clothing manufacturing for Chinese women in their 20s residing in Ningbo City, Zhejiangsheng, China, this study analyzes their upper-body types. With the subjects of 192 female adults(age 20 to 29), the following conclusions were made: 1. According to the Chinese standard classification, all body types except C were seen: A(58.33%), Y(40.63%), and B(1.04%). 2. According to the Korean standard classification, body types appeared in the order of H(68.75%), N(29.17%), and A(2.08%). 3. $R\ddot{o}hrer$ index was 1.23 belonging to the ordinary somatotype. The distribution was ordinary(60.42%), slim(38.54%), and fat(1.04%). 4. The subjects were 158.62cm(height), 83.54cm(bust), 65.77cm(waist), and 87.50cm(hip). 5. No significant differences were noticed in all the items except waist breadth around age 24. 6. Compared with Korean counterparts, Chinese females were a little shorter, had bigger bust, similar waist, and smaller and flatter hips. 7. Seen in the side somatotype classification, a standard body type was revealed with $24.50^{\circ}$ of a slightly-leaning shoulder gradient. 8. Seven factors were produced in the present analysis, and five body types in the group analysis turned out to be standard.

  • This study analyzed mycotoxins, aflatoxin B1, B2, G1, G2, fumonisin B1, B2, ochratoxin A and zearalenone, using LC-MS/MS and conducted risk assessment on 54 samples of seeds distributed in SeoulYangnyeongsi and the management status of extramural herbal dispensary facility. The matched calibration showed a good linearity as observed in 6 concentration levels(r2>0.999) as a result of method validation applied with Arecae semen. Limits of detection(LOD) and quantification(LOQ) were in the range of 0.02-0.11 ㎍/kg and 0.08-0.34 ㎍/kg, respectively. Recoveries also estimated, ranging from 65.1-99.7% with relative standard deviation(RSD) 0.5-6.3%. As a result of the method on 54 samples, mycotoxins were detected in 16 samples. Among them, two Thujae semen showed a degree of concentration that exceeded the aflatoxin specification. In the risk assessment, the human exposure safety standard values were calculated as ADI(Acceptable Daily Intake) for aflatoxin B1, fumonisin and zearalenone. Ochratoxin A was calculated as PTWI(Provisional Tolerable Weekly Intake). The MOE(Margine of Exposure) of aflatoxin B1 was in the range of 40.36-3536.88. And no items exceeded 100% in %TDI(Tolerable Daily Intake) and %TWI(Tolerable Weekly Intake) of fumonisin, zearalenone and ochratoxin A.
