저자들은 마우스를 실험모델로 하여 간흡충의 항원을 투여 했을 때 비장조직에 대한 CD3, CD4 및 CD8 모노클로날 항체의 반응 여부를 알아보고자 하였다. 즉, 간흡충에 대한 세포면역학적인 특성을 규명고자 하였으며 특히 비장 조직에 대한 phenotype을 관찰한 결과 다음과 같은 결과를 얻었다. 간흡충의 조항원을 면역증강제와 함께 복강 투여한 다음 일정 기간 후에 비장조직을 Avidin-biotin complex 면역조직염색을 실시한 결과 CD3에서 강한 양성 반응을 나타냈고 CD4와 CD8에서는 약한 반응을 나타냈다. 조직부위를 보면 피막, 혈관, 임파관, 백수부위와 림프구 및 대식세포의 세포막에서 양성반응을 보였다. The authors inquired into what reactions comprise the response of mice(as a model) CD3, CD4 and CD8 monoclonal antibodies in spleen tissue when injected intraperitoneally by antigens of Clonorchis sinensis. The author is objective was focused on investigating the property of cellular immunity for liver fluke. In particular, the results of having examined the phenotype of the tissue of spleen were revealed as follows: a certain length of time after having been intraperitoneally injected with antigens of Clonorchis sinensis and Freund's adjuvant, the tissue of spleen was embedded and immunohistochemically stained by the avidin-biotin complex method. A strong reaction in response to CD3, while a feeble reaction resulted from CD4 and CD8. The tissue region showed a positive reaction to all antibodies, especially from capsules, vascular areas, white pulps and membrane of blood cells.

Enantioselective Synthesis of <i>anti</i>–<i>syn</i>-Trihalides and <i>anti</i>–<i>syn</i>–<i>anti</i>-Tetrahalides via Asymmetric β-Elimination

Tan, Yu,Luo, Shilong,Li, Dongmei,Zhang, Nan,Jia, Shiqi,Liu, Yidong,Qin, Wenling,Song, Choong Eui,Yan, Hailong American Chemical Society 2017 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.139 No.18

<P>Structural motifs containing contiguous halide bearing stereocenters are common in natural products as well as bioactive molecules. A few successful examples have been reported in the area of asymmetric vicinal dihalogenation of alkenes for accessing dihalogenated products; in this report, an alternative generation method of contiguous halide-bearing stereocenters alpha,beta,gamma,delta relative to carbonyl group in excellent enantioselectivity is proposed by utilizing a Song's oligoEG catalyst-catalyzed asymmetric beta-elimination. According to this methodology, a wide range of anti-syn-trihalides and anti-syn-anti-tetrahalides with high levels of enantioselectivity were synthesized. The synthetic utility of the contiguous halide-bearing stereocenters was demonstrated by several transformations. The results of high-resolution mass spectrometry indicated that the favorable interaction between catalyst and one of the enantiomers of racemic contiguously multihalogenated ketone contributed to the original enantioselectivity of dehydrohalogenation. A deuterium kinetic isotope effect experiment revealed that this beta-elimination reaction proceeds by the E2 mechanism. This strategy opens a new pathway for the asymmetric synthesis of contiguous halide bearing stereocenters of great complexity.</P>

This study was designed to investigate the effect of a year aerobic exercise training on body composition, isokinetic knee and trunk muscular strength of elders. The subjects for this study were eighty healthy elderly people who were members of seniors tower at Song-Do Hospital and didn`t have any history of cardiorepiratory disease. Subjects have been trained three times a week for a year. The exercise program was made up of a 15-minute warm-up, cool-down. Stretching was performed every eight minutes for the prevention of injuries which could occur during the main exercise and quick recovery of the used muscle. Aerobic training was performed for each 15-20minutes using the treadmill and cycle ergometer at the intensity of 50-70% HRmax. For the data, all the measurements were represented by mean and standard deviation using SAS package(version 6.12). Statistical techniques for data analysis were paired t-test to determine the difference between pre and post exercise program. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. The following results were obtained from this study. 1. There is a statistically significant difference in the VO_2max, fat mass, lean mass and %body fat both old men and women after a year training. 2. There is not a statistically significant difference in the weight, WHR and thigh circumference both old men and women after a year training. 3. There is a statistically significant difference in the right knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training. 4. There is a statistically significant difference in the left knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training.

Ultrasonic Evaluation of Creep Damage in 316LN Stainless Steel

Song-Nan Yin,Yeong-Tak Hwang,Won Yi 한국정밀공학회 2007 International Journal of Precision Engineering and Vol.8 No.4

Creep failure of 316LN stainless steel (SS) occurs due to the nucleation and growth of cracks. An investigation was performed to correlate the creep damage with ultrasonic wave speeds and angular frequencies using creep-tested 316LN SS specimens. Ultrasonic wave measurements were made in the direction of and perpendicular to the loading using contact probes with central frequencies of 10. 15. and 20 MHz. We found that the angular frequency and wave speed decreased with increasing creep time to rupture by analyzing the ultrasonic signals from the 15 and 20 MHz probes. Therefore, the creep damage was sensitive to the angular frequency and wave speed of ultrasonic waves.

Electrolytic polishing of the inner surface of SUS316 for hydrogen by high current method

Nan Song(송남),B.H. Son(손병학),Jeong-In Han(한정인) 대한전기학회 2021 대한전기학회 학술대회 논문집 Vol.2021 No.10

Electrolytic polishing is more efficient and accurate than mechanical polishing, and it is not affected by the hardness and toughness of the material, so it tends to gradually replace mechanical polishing. Especially for precision instruments, aviation, medical devices are widely used. Now most of the polishing field is for stainless steel and titanium alloy external surface research, and for stainless steel and titanium alloy sample internal polishing research is not much. We are now electrolytically polishing the inner surface of SUS316 to explore the conditions for rapid polishing of SUS316 in a short time.
