  • The effect of water temperature and feed on the growth, survival, and body composition of juvenile abalone (Haliotis discus hannai) fed an artificial formulated diet and a macroalgae (Laminaria japonica) for 12 weeks was investigated. Rearing temperature was maintained at $13{\circ}C,\;16{\circ}C,\;19{\circ}C$ by heated and natural sea water temperatures $(7.5-10.2{\circ}C).$ Shell growth, weight gain, and survival rate of the abalone were affected by water temperature and diet (P<0.05). Survival and growth rate of the abalone fed with the formulated diet and Laminaria at $19{\circ}C$ was significantly higher than those of the abalone fed the formulated diet or Laminaria at $13{\circ}C,\;16{\circ}C,$ and ambient temperatures (P<0.05). Moisture, crude protein, crude lipid, and ash contents of the soft whole body were affected mainly by diet than rearing water temperature (P<0.05). These indicate that a mixture of formulated diet and macroalgae could improve the growth of the abalone independent of water temperature and heated water could improve the growth of abalone during the winter season.

  • The purpose of this study is to female child Han-bok reform design for body growth. Nowadays there is common the western style daily life and special day instead of traditional style Han-bok in Korea. So the decrease in the use of Han-bok have being appeared. Specially, Children's Han-bok undesirable clothes for economic, environment, and resources because of their rapid growth and changing trend. Therefor, they do away with used Han-bok without next buying of school age. Children's parents and children are decision together purchase of children's Han-bok on-line for pleasure and economic reasons on pre-school or 1st year student for their tradition-education class. After 2000year, children's Han-bok pup-up on e-market because of the fashion focus on tradition and Korean wave for parody of Korean drama. Flowing the Research of 2010 Size Korea, the elementary school age child height growth 6cm per year, the sleeve length are 3cm growth. But Chi-ma(a pice of Han-bok) from e-market, has only 5cm margin on shoulder and no margin on Jegori(a pice of Han-bok) shoulder and sleeve, reason of that the children can't wear next year. Therefor this study is development female child Han-bok reform design for body growth, for extend to wear Han-bok on school age children and flow tradition custom of Cho-sun Dynasty's clothing custom for boost tradition conscious and reduce of cloth waste for environment.

  • We studied and compared the age structure, body size, and growth rates of field populations of two Korean salamander species (Hynobius yangi and Hynobius quelpaertensis) to elucidate important aspects of basic population dynamics of these two endemic Hynobius species. In both populations, females were sexually mature at three years of age, while H. yangi and H. quelpaertensis males matured at two and three years of age, respectively. Both males and females of H. yangi and H. quelpaertensis attained a maximum age of 11 years and 10 years, respectively. In both species, the snout-vent length (SVL) and body weight (BW) of the females were greater than those of the males. The SVL, BW, and asymptotic SVL of both male and female H. yangi were smaller than those of H. quelpaertensis. The adult growth rates after sexual maturation of male and female H. yangi were lower than those of H. quelpaertensis, possibly resulting in the smaller body size of the former, although overall growth coefficients were not significantly different between the two species. We also compared the age structure and growth rates of three Korean and three Japanese species of Hynobius.

  • We have studied anemarrhena asphodeloides, a hair growth promoter as an alternative medicine agent to compensate for the disadvantages of minoxidil, which has excellent hair growth promoting effect on follicular epithelial cells. anemarrhena asphodeloide, an Rhizome plant of aemarrhena asphodeloide family, is a traditional medicinal plant used in Korea as an antipyretic, antidiabetic, antidepressant, antiinflammatory. We applied and observed anemarrhena asphodeloides ethanol extracts to the back of mice, and there was no significant difference in body weight and food intake among all groups of mice. The ethanol extract of anemarrhena asphodeloides showed vigorous hair growth promoting effect without changing the serum composition and thus it is considered to be useful as a hair growth promoter in the future.

  • Purified diets containing five graded levels of tryptophan were fed to growing chicks to evaluate tryptophan requirements for growth and maintenance. A model was developed to separate tryptophan requirement for maintenance from requirement for growth. From this model, the daily tryptophan requirement for growth was 2.16 mg/g gain, and the daily requirement for maintenance 0.029 times metabolic body size ($Wg^{0.75}$). Based on nitrogen gain response, the tryptophan requirement for growth was 0.078 mg/mg N gain, and the daily maintenance requirement was 0.029 times metabolic body size. The total tryptophan requirements were 71.56 mg/day or 0.173% of the diet, 69.48 mg/day or 0.168% of the diet based on the weight gain response and nitrogen gain response, respectively. Previous tryptophan requirements for growing chicks aging 1-28 days are in close agreement with these estimates. Based on the relationship of weight gain and N gain, about 1.25% of the retained CP was consisted of tryptophan; the previously reported value of tryptophan content of chick muscle CP was 1.03%.

  • Purified diets containing five levels of methionine with 0.4% cystine were fed to growing chicks (8 days old male Arbor Acre strain) to evaluate methionine requirements for growth and maintenance. A model was developed to separate methionine requirement for maintenance from requirement for growth. From this model the daily methionine requirement for growth was 4.22 mg/g gain, and the daily methionine requirement for maintenance was 0.034 times metabolic body size ($W^{0.75}$). Based on nitrogen gain response, the methionine requirement for growth was 0.162 mg/mg N gain, and the daily maintenance requirement was 0.037 times metabolic body size. The plateau of plasma methionine concentration reached at 117.16 mg intake pre day. The total methionine requirement determined based on weight gain response was 138.29 mg/day or 0.33% of the diet and the one determined based on nitrogen gain response was 141.7 mg/day of 0.34% of the diet, respectively. As a percentage of protein, methionine was calculated to be 2.6%; the reported methionine content of carcass CP was 1.76%.

  • This experiment was carried out with 12 Korean native heifers(8~12month old, body weight, 160~240kg) raised at a farm of Chang-Soo Livestock Cooperatives to evaluate the effects of rGH(recombinant growth hormone) on serum concentrations of growth hormone, estrogen, and IGF-I, weight gain, teat volume gain and processing enzyme activity of IGF-I, binding protein III at 28 day intervals. Animals used were injected with 250mg rGH at 14 day intervals from December to Ferbruary in 1994. The significant difference was found in the group of treatment on the 4th week in the endogenous GH(p<.01) and 8th week in estrogen and IGF-I(p<.05) after injectin of rGH in Korean native heifers. There were significant differences between control group and treatment group in weight and teat volume on 8th week after treatment(p<.05). Processing enzyme activity before injection of rGH were low. However, heifers injected with 250mg of rGH showed that processing enzyme activity of IGF binding protein was highly increased throughout the experiment. Present results suggest that injection of exogenous rGH to heifers can increase the growth performance and udder development of Korean native heifers by the endogenous hormonal changes.

  • In this Part 2, the grain growth processes of $Al_2O_3$ ceramics is numerically simulated using Monte Carlo method (MCM) and finite element method (FEM) and the pore sizes are analyzed. As the green ceramics whose thermal conductivities in high temperatures are generally low are sintered by the plasma heat and are rapidly cooled, the grain growth of the sintered body in the center is different from that in the outer. Also, even in the same sintering temperature, the pore size differs according to the pressing pressure. In order to prove the difference, the temperature distribution of the sintered body was analyzed using the finite element method and then the grain growth process associated with pressing pressures and relative densities was simulated using Monte Carlo method.

  • This study was carried out to obtain basic data on physiological characteristics for an artificial cultivation of fruiting body of C. pruinosa. C. pruinosa showed the most favorable growth on the MCM medium. The optimal condition for the mycelial growth was obtained at 25$^{\circ}C$ and pH 5.0, respectively. Carbon sources such as arabinose, mannose, xylose were favorable for stimulating a mycelial growth and fruiting bodies of C. pruinosa. Ammonium nitrate, ammonium citrate and ammonium tartrate of nitrogen sources also appeared to be good in the mycelial growth and fruiting body formation.
