This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

This study was to investigate the cause of the color and turbidity in a small-scale water treatment plant using lakes water as water supply source. Water qualities in aqueducts, in depth of the lakes and in each process were measured. And effects of prechlorination on each unit operation in the water treatment, especially on iron and manganese removal, were studied. The concentration of iron and manganese was 0.13, 0.08 mg/L in the surface water and 1.93 and 0.433 mg/L in 15 m depth of the lake. Higher iron concentration of the inlet was measured to 5.35 mg/L which was caused by the steel aqueduct corrosion. The optimun coagulation dosages of Poly Aluminum Chloride(PAC) and Liquid Aluminum Sulfate (LAS) were 17.5 mg/L and 35 mg/L. Pretreatmnet of raw water with CaCOl improved the removal efficiencies of iron and manganes. However, more efficient method for removing iron and manganes was required.

The influence of extracellular calcium ions on adrenergic activation of glycogen phosphorylase was studied in isolated rat hepatocyte. Treatment of isolated hepatocytes with epinephrine, phenylephrine and isoproterenol elicited a dose-dependent increase in stimulation of phosphorylase activity. The time course of the activation of phosphorylase by adrenergic agonists was investigated in hapatocytes incubated either with a physiological concentration of extracellular Ca^2+ (2.6mM) or in a medium containing no added Ca^2+. The basal activity of phosphorylase was decreased by approximately 75% in hepatocytes incubated in the low Ca^2+ medium. The addition of adrenergic agonist caused a rapid increase of phosphorylase in cells incubated in the high or low Ca^2+ medium and enzyme activity decreased gradually after reaching a maximum 5 min after adrenergic agonists addition, and basal activity was not attained over the 10-min period of the time course. The magnitude of the maximal stimulatory effect was significantly decreased by the absence of extracellular Ca^2+. The stimulation of phosphorylase induced by epinephrine in the high or low Ca^2+ medium was no longer apparent after 30 min, but a second addition of epinephrine at this time can restimulate phosphorylase to an extent similar to that of a first addition. The addition of CaCl_2 to cells exposed to epinephrine and phenylephrine for 10 min in a medium having a low extracellular Ca^2+ produced a further increase of phosphorylase activity which was larger than the changes observed upon CaCl_2 addition to untreated cells. In order to obtain more information about the mechanism of Ca^2+ entry across the plasma membrane, we investigated the effects of calcium channel blockers on epienphrine-induced phosphorylase activation. Pretreatment of the diltiazem, verapamil, and nifedipine interfered with the magnitude of the maximal effect mediated by epinephrine; the kinetics of the enzyme activity in nifedipine-treated cells was found to be different from that of other channel blockers. These results suggest that entry of extracellular Ca^2+ into the cell is required in order to obtain a sustained adrenergic stimulation of phosphorylase activity and to supply the intracellular Ca^2+ store. The results also indicate that calcium channel blockers inhibit the transport of Ca^2+ across the plasma membrane through a putative Ca^2+ transporter which differs in nature from potential-operated calcium channels in excitable cells.

본 논문에서는 DCT(discrete consine transform)를 이용하여 영상 데이터를 공간 영역에서 주파수 영역으로 변환하여 주파수 영역별로 분해한 뒤, 윤곽선 추출과 압축을 동시에 하기 위한 여러 양자화 테이블을 적용하고, IDCT(Inverse DCT)를 이용하여 복원한 결과를 비교 분석함으로써, 보다 정확한 윤곽선을 가진 영상을 추출할 수 있는 양자화 테이블을 구했다. 이 양자화 테이블을 DCT 처리된 영상에 적용했을 때 윤곽선과 압축 효과를 가진 영상을 얻을 수 있었다. In this paper, we transform image data from spatial domain to frequency domain using DCT, decompose it into each frequency band. We apply various quantization table for edge detection and compression simultaneously. We researched a quantization table for extracting image with exact edge, as compare and analyze restored images using IDCT. When we applied this quantization table to the DCT transformed image, acquired the image with edge and compression effect.

활막성 연골종증은 비교적 드문 양성 종양으로 관절내 활액막 결체조직의 양성 반응성 이형성에 의해 여러 개의 연골성 결절을 형성하고 이것이 관절내로 유리되어 유리체를 형성하는 질환으로 주로 슬관절에 발생한다. 활막성 연골종증의 정확한 발생 기전은 아직 밝혀지지 않았으나 외상, 감염 등이 원인으로 제시되고 있다. 저자들은 슬관절 내 히야루론산 주입후 발생한 슬관절내 활막성 연골종증을 1 례 경험하였으며, 관절경적 제거술을 통해 만족스런 결과를 얻었다. As a relatively rare benign tumor, synovial chondromatosis forms several cartilaginous nodules by the benign reactive metaplasia of synovial connective tissues within joints, which are loosed into the joints and cause a disease forming loose body mainly in knee joint. Accurate mechanism of synovial chondromatosis has not been clarified yet; however, trauma, infections and others have been suggested as its possible causes. The authors of this study experienced an example of a patient with synovial chondromatosis in knee joint occurred after the injection of hyaluronic acid in the joints and had a satisfactory outcome through the arthroscopic resection.
