  • This study was performed to determine the level of soybean meal (SM) or feather meal (FM) that could substitute for fish meal in fat cod(Hexagrammos otakii Jordan et Starks) diet. A control diet with fish meal as protein source was included. The amount of 5, 10, 15 and 20% of SM or FM substituted for fish meal in the control diet, respectively. Amino acids supplementation in the 20% SM diet was compared. In addition, combination of 5% SM, 5% corn gluten meal, 5% meat meal, 5% blood meal and 5% FM was substituted for fish meal in the control diet. Duplicate groups of the 40 fish averaging 21g were fed one of 11 isoproteic (45%) and isolipidic (15%) experimental diets to satiation twice a day for 2 months. No significant differences were found among fish fed the control, substituting up to 20% SM or 10% FM in weight gain, feed efficiency, daily feed intake, and protein efficiency ratio (P>0.05). It is concluded that SM or FM can be used as a partial substitute for fish meal up to 20% or 10% in the control diet, respectively.

  • 본 논문은 관상동맥의 구조와 그 움직임을 사실적으로 표현하기 위한 매개변수적 모델링기법을 제안한다. 매개변수적 기법으로 생성된 모델은 메쉬 정점의 인덱스만으로 모델간 매칭을 위한 대응점을 찾을 수 있으므로, 시간대별로 달라지는 정점의 위치를 쉽게 추적함으로써 모델의 움직임을 표현할 수 있다. 그러나 이러한 기법으로 생성된 모델은 분리, 접합 등의 변형 조작이 어렵고, 트리형태 객체에 적용하기 힘든 단점이 있다. 본 논문에서는 이를 극복하기 위해 분할된 혈관영역의 골격데이타에서 찾아낸 분기점을 중심으로 Generalized Cylinder를 이용하여 실린더 형태의 각 혈관세그먼트를 모델링 한 후, 분기영역을 3 개의 하프파이프(half pipe)와 2 개의 삼각형 패치로 연결하여 모델링하였다. 완성된 모델은 다시점 관상동맥데이터에 적용하였고, 각 시점에서 구해진 정점의 위치를 선형보간함으로써 부드러운 혈관의 움직임을 나타내었다.

  • In this paper, a new Open and Closed Loop Alternation(OCLA) frequency synthesizer is developed to eliminate a frequency error occurring in the transition state of a frequency hopping. This frequency synthesizer consists of a phase comparator(PC), two low pass filters(LPF), two voltage controlled oscillators(VCO), switching elements, a programmable divider and frequency hopping controller, and the stabilized output frequency can be obtained by switching performance. In addigion, it can be found that the characteristic of its circuit construction makes it easy to attach an external circuitry to the open loop.

  • For effective production of interspecific hybrids of Lilium and valuable new cultivars, we used Lilium Asiatic hybrid 'Tiny Ghost' as the female parent, and Oriental group, and Longiflorum group and Martagon as the male parents. Percentage pollen germination in Oriental hybrid 'Sorbonne' was the highest with 64%. As results of using normal style pollination and cut style pollination methods, all seed sets were formed in normal style pollinated treatment, except in 'Aktiva'. Pollen germination percent of Longiflorum hybrid 'Norina' was higher than that 'Gelria'. However, all crossings using 'Norina' failed to set seeds. Corresponding fertilization ratio was different from genetic compatibility, even in the same group. From the crossing using 'Aktiva' as the male parent one bulb was obtained derived from one embryo sac. And using 'Sorbonne' as the male parent, one plantlet was obtained after four ovule cultures. Crossing using 'Gelria' as the male parent five embryos, 15 embryo sacs, and seven ovules per one ovary were obtained. Among them, 18 plantlets germinated, with the germination percent of 66.7%. Crossings using L. hansonii, Martagon group, as the male parent resulted in 40% germination from five ovules.

  • This paper proposes a convex hull algorithm for 2D patterns. The proposed algorithm is divided ito 2steps; candidate convex point extraction and final convex point extraction. First step removes as many points as possible that cannot be convex points using simple operation. Second step computes final convex hull of 2D patterns. This method accelerates execution time, since it consists of simple operations. Experimental results show that the proposed method is faster than other 2 methods in speed.

  • In this study, we investigated the quality of glasswort (Salicornia herbacea L.) fermented by Bacillus subtilis at $37^{\circ}C$ for 48 hours. We determined the changes in temperature, the contents of moisture, crude protein, crude fat, crude ash, carbohydrate, solid content, pH, Brix, salinity, free amino acid, Hunter's color value, electron donating ability (EDA) activities and angiotensin converting enzyme (ACE) inhibition. The contents of crude protein, crude fat, crude ash and carbohydrate after fermentation to mixing ratio of glasswort were $10.45{\sim}30.18%$, $11.69{\sim}19.26%$, $17.65{\sim}25.56%$ and $21.01{\sim}59.10%$ (dry basis), respectively. The solid content, pH, sugar and salinity of fermented glasswort were $39.56{\sim}52.25%$, $6.01{\sim}6.71$, $1.2{\sim}1.7$ Brix and $0.3{\sim}0.6%$, respectively. Total amino acid level of the fermented glasswort was $447.57{\sim}668.89\;mg$/100 g, and was the highest in glasswort mixed with rice bran at a ratio of 1 (w) : 1 (w). Moreover, aspartic acid, asparagine, glutamic acid, alanine, valine, $\beta$-aminoisobutyric acid, lysine and arginine were the main free amino acids. EDA activities and ACE inhibition after fermentation were $46.66{\pm}1.21{\sim}50.87{\pm}1.84%$ and $96.77{\pm}1.23{\sim}97.56{\pm}1.23%$, respectively.

  • The effects of bisphenol A (BPA), known as one of the endocrine disrupting chemicals (EDCs), on the hatching of fertilized eggs (FE) and the spawning of adult fish in songsari, Oryzias latipes were investigated. In condition of the experimental groups, incubated water temperature was $25.0{\pm}0.5^{\circ}C$ and photoperiod was 16 h (light) : 8 h (dark). fE were exposed to aqueous solutions of BPA at nominal concentration of 50, 100 and $200 {\mu}g/l$. The time required in hatching of FE was long in the BPA $50 and 100 {\mu}g/l$ treatment groups when compared to the controls, and in the BPA $200 {\mu}g/l$ treatment group, FE failed to hatch. And also hatching rate was decreased in the BPA treatment groups in comparison to the controls, Adult fishes were reared to oral administration via a diet of 50, 100 and $200 {\mu}g/g$ body weight BPA concentration for 3 weeks, Number of total eggs spawned in the adult fish were fewer in the BPA 100 and 200 treatment groups than in the controls and BPA 50 treatment group. Frequency of abnormal eggs in the total eggs spawned was 11.8 and $16.2{\%}$ in the control and acetone carrier control lower than 36.8, 46,8 and $74.1{\%}$ in the BPA 50, 100 and 200 treatment groups, respectively. And hatching rate of FE decreased in the BPA treatment groups in comparison to the controls. In these results, inhibition of the hatching of FE and the quantity and quality of spawned eggs in adult fish were observed from BPA treatment groups when compared to the controls.

  • Salinity and drought stresses are probably the most significant abiotic factor limiting plant's growth, also negatively affect seed germination and early seedling development. To study on effect of NaCl and PEG stress on seed germination and gene expression pattern of tall fescue, the levels of NaCl and PEG-induced water stresses were determined in first experiment. Different concentration of NaCl (0 to 350 mM) and PEG (0 to 30%) were used for seed treatment. Seed Germination percentage reduced with increasing osmotic potential of growth medium either due to NaCl or PEG. Seeds were not germinate at 350 mM NaCl or 30% PEG treatment. On the basis of the results, Kentucky31(E-) had more resistant than Fawn in both stress conditions. Furthermore, we have used an annealing control primer-based differential display reverse transcription-polymerase chain reaction method to identify salt- and drought stress-induced differentially expressed genes (DEGs) in tall fescue leaves. Using 120 annealing control primers, a total of 4 genes were identified and sequenced. The possible roles of the identified DEGs are discussed in the context of their putative role during salinity and drought stresses.

  • Ketamine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist and a short-acting general anaesthetic agent for human and veterinary use. We previously reported that treatment with ketamine impairs oxidative burst activity of canine peripheral blood leukocytes. In this study, the effect of ketamine on phagocytic capacity of canine peripheral blood leukocytes was examined in vitro. Phagocytic capacity was analyzed by using a flow cytometry. Ketamine directly decreased the phagocytic capacity of peripheral blood polymorphonuclear cells (PMN) and monocytes but not total peripheral blood mononuclear cells (PBMC). In addition, the phagocytic capacity of PMN and monocytes was inhibited by the ketamine-treated PBMC but not PMN culture supernatant. These results suggest that ketamine has a direct inhibitory effect on the phagocytic capacity of canine peripheral blood phagocytes and involves the production of soluble factor(s) from canine PBMC, which may suppress the phagocytic capacity.
