光의 照射에 의한 콩나물의 質的變化를 調査할 目的으로 光度 및 光質別 處理를 하여 成長狀態, Vitamin C, chlorphnyll, cellulose등의 含量과 質感에 對한 官能檢査를 行하였으며 chlorophyll과 vitamin C의 關係를 chloramphenicol 處理에 의하여 調査해 보았다. 그 結果 白色光의 경우 50 lux와 100 lux 處理로 vitamin C의 含量 增加와 cellulose등의 生成이 促進되었으며 質感이 暗所보다 良好하였다. 그러나 200 lux 하에서는 매우 不良하였다. blue光은 他光보다 cellulose와 vitamin C生成에 效果的 이었다. chlorophyll과 vitamin C의 含量과는 直接的인 關係가 없고 다만 光照射와의 關聯性이 있는 것으로 推定되었다. This study was carried out to evaluate the quality of green soybean sprouts grown under light. The soybean was germinated under light through blue, red and white polyethylene films at 25℃ for 10 hours a day, and light intensity was controlled 50 to 200 lux. The contents of Vitamin C. cellulose and chlorophyll were determined and checked up texture by sensory evaluation of the soybean sprouts soup. In addition, the relationship of chlorophyll and Vitamin C was measured by treatment of chloramphenicol which has inhibitory effect of chloroplast, chlorophyll accumulating site. Vitamin C and cellulose contents were all increased by irradiation of white light at 50 and 100 lux and also texture of the sprouts was better than it of the sprouts grown under darkness while, it was very tough under 200 lux. Blue light was more effective for biosynthesis of Vitamin C and cellulose than white and reg light. Biosynthesis of chlorophyll was not relative to Vitamin C content directly. but the relationship may be concerned with light irradiation.

Human genomic DNA prepared from whole blood sample was analyzed to estimate allelic frequencies and genetic diversity at a hypervariable variable number of tandem repeats(VNTR) D1S80 locus in 127 Korean. Target DNA fragments were amplified by polymerase chain reaction(PCR) and separated by polyacrylamide gel electrophoresis. Then, the following results were obtained. 1. A total of 23 alleles were identified at this locus, which is the biggest number of alleles observed at this locus so far(cf. 16 from U. S. Caucasians and 15 from Finnish). 2. Sixty-two genotypes, included 3 homozygotes and 59 heterozygotes, out of a total of 276 probable genotypes were also observed, which might be resulted from the small sample size compared to the number of alleles observed in this study. 3. General pattern of allelic distributions was concordant with those observed in previous studies from Finnish and U. S. Causccasians where two alleles, M18 and M23, were observed most frequently and the rest of them were observed rare(<10%) with the exception of M30 allele(14.6%) in Korean. The number of M30 allele is suspected to be increased in Korean at or after the divergence of Korean from the hypothetical ancestor probably caused by random genetic drift such as founder effect of bottleneck effect. 4. Higher level of heterozygosity was obtained in Korean(H=0.866 and H=0.881) than in Finnish(H=0.77 and H=0.79) and U. S. Cauccasians(H=0.808 and H=0.797). 5. Population homogeneity was tested to corroborate the obtained population genetic parameters calculated based on the assumption of Hardy-Weinberg equilibrium, which could be done by Chi-square test between the observed number of alleles and the expected number of alleles, because of the small sample size analyzed in this study which resulted in high proportion of undetected genotypes (78.5%) and several genotypes significantly deviated from hardy-Weinberg expectation in a sample population. The result suggests that samples were drawn from geneticically homogeneous population. 6. This study suggests that Korean is more diversified than Finnish and U. S. Cauccasians on the basis of the number of alleles and the level of heterozygosity, although Korean is known to be entirely composed of single race. Though we need more informations from other Asian countries, this result suggests frequent gene flow from neighbor countries, which is also expected based on the old Korean history of frequent invasions from Japan and China. 7. Based on the Hardy-Weinberg expectation, 216 out of 253 genotypes at D1S80 locus can be shared by less than 5 individuals among 1,000 unrelated individuals by chance. Our results suggest that the analysis of VNTR D1S80 locus can provide powerful, but imperfect by itself, DNA markers for forensic study, which can be corroborated by analyzing additional VNTR loci.

김명철,이명숙,유병철,이용환 고신대학교의과대학 2007 고신대학교 의과대학 학술지 Vol.22 No.2

Background and Objectives: The -250G to A polymorphism of the hepatic lipase gene (LIPC) has been associated with lowered hepatic lipase activity, dyslipidemia, and diabetes. The aims of this study were to elucidate the relationship of the G-250A polymorphism of LIPC with metabolic syndrome in Koreans. Methods: A total of 943 health screen examinees were enrolled in this study who were examined in Kosin University Gospel Hospital from December 2004 to February 2006. The height, weight, body mass index, body fat mass, visceral fat mass, waist circumference, and systolic and diastolic blood pressure of the subjects were examined and fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride were measured by sampling in venous blood. The metabolic syndrome was defined as the presence of three or more of the following : waist circumference men≥90 cm, women≥80 cm, blood pressure≥130/85 mmHg, fasting glucose≥110 mg/dL, HDL cholesterol men<40 mg/dL, women<50 mg/dL, triglyceride≥150 mg/dL. The blood pressure, fasting glucose, HDL cholesterol, triglyceride were evaluated by using the criteria of NECP ATP Ⅲ and waist circumference was assessed by using the criteria of WHO Asia-Western Pacific. The genotype at position -250 of the hepatic lipase promoter was determined by single base extension and electrophoresis. Results: The observed frequencies of the -250G to A polymorphism of LIPC were 49.8% for the metabolic syndrome, 51.4% for the control group and 50.9% in total subjects. The frequency of the A allele was 36% in total subjects. Concentration of triglyceride was significantly higher in subjects with GA and AA genotypes in women.. Conclusion: The -250A allele frequency was 36% in Koreans and the -250G to A polymorphism of LIPC seems to significantly influence to plasma triglyceride levels in women.

Non-medical use of drugs to enhance performance at Olympic Games by athletes has been prohibited by the International Olympic Committee(IOC) since 1968 on medical and ethical grounds. IOC wants to protect athlete from harmful side effect of drugs due to misuse of it. It also, ethically, wants to have Games run on fair base, not fortified by performance enhancing drugs. The banned substance include stimulants, narcotic analgesics, anabolic, steroids, β-blockers and diuretics. In order to prevent the positive reaction in the doping test induced by herb medicine, this study was done on about Bojungchisheup-tang. The laboratory set up doping analyses methods to cover as many drugs as possible without sacrificing sensitivity and specificity within one procedure. Its screening method considered of four different procedures. The results were negative. According to the above results, Bojungchisheup-tang taken by athletes would show the negative reaction in the doping test. So its prescription for athletes can be given without worries of the doping test.

김상진,이형규,위명용 충북대학교 컴퓨터정보통신 연구소 2001 컴퓨터정보통신연구 Vol.9 No.1

GaN 에피층을 CCl2F2 와 Ar 가스를 사용한 RIE로 건식각 공정을 개발하여 청색발광용 DFB 레이저 다이오드의 회절격자를 제작하였다. 회절격자의 패턴은 레이저 홀로그래피와 최적조건의 식각 조건 하에서 제작되었다. 얇은 감광제만을 식각 마스크로 사용하면 플라즈마에 의한 마스크 침식에 의해 불규칙적이며 굴곡이 있는 회절격자가 형성되었다. 반면 SiO2/감광제 이중 마스크를 사용하면 마스크 침식 현상이 현저히 감소하여 매우 선명하며 주기적인 격자를 형성할 수 있었다. 제작된 회절격자는 주기 0.25 ㎛, 깊이 약 50nm 인 정현파 형태를 가지고 있었다. We investigated RIE etching parameters of GaN using CCl2F2 and Ar gases and fabricated DFB gratings for the GaN based blue laser diode. Grating patterns were defined by the laser holography followed by RIE etching. Using thin PR as an etch mask, the mask erosion was severe to render the etched pattern rough and aperiodic. However, when SiO2/PR double mask was employed, the mask erosion problem was greatly reduced and a sharp and periodic pattern was obtained. the fabricated grating had a sinusoidal shape with period of 0.25 ㎛ and depth of 50 nm.

The corrosion behaviors of Zr-based alloys were investigated with a series of Zr-1.5Nb-xSn ternary alloys which had the variations of β_(Nb) content and final annealing condition. As a result of microstructural study, the _(enriched) was observed in the samples annealed at 640℃, regardless of Sn content. The volume fraction of the precipitates and the Nb concentration in the precipitates did tend to be increased with increasing the Sn content. The samples annealed at 470℃ and 570℃, where β_(Nb) precipitated, exhibited better corrosion resistance than those annealed at 640℃ where β_(Zr) precipitated. The corrosion resistance of the Zr-1.5Nb-xSn alloy system did tend to increase with increasing Sn content. This would be resulted from the reduction of Nb solubility in matrix with increasing Sn content. Thus it eventually facilitate the formation of β_(Nb) phase from the solid solution state of Nb in Zr matrix. The Nb concentration in β_(Nb) phase increased with increasing the Sn content. This would contribute to the formation of β_(Nb) from soluble Nb that existed in the solid solution of Zr matrix.

이용달,박명규,김세덕,방경윤,안일신 한양대학교 이학기술연구소 2000 이학기술연구지 Vol.2 No.

A zero-order retarder was fabricated using two pieces of magnesium fluoride plates. In order to achieve desired zero-order retardation for specific wavelength, both the thickness of plates and the alignment of two fast axes were very important. We found that the alignment should be checked using broad band detection system for spectroscopic application, We devised alignment method by which the two fast axes lie perpendicularly to each other. The periodic oscillation feature in retardation angle versus wavelength disappeared with good alignment. We also developed calibration method to deduce the retardation angle over a wider spectral range using rotating compensator ellipsometer. 두 조각의 마그네슘 플로라이드 판을 이용한 0차 retarder를 제작하였다. 특정한 파장에 대하여 원하는 0차 retardation을 얻기 위해서는 판의 두께와 alignment가 매우 중요하였다. 분광학적인 응용을 위해서는 넓은 파장 영역을 측정할 수 있는 detection system의 사용이 필요하였다. 이를 이용하여 두 판의 fast axes가 서로 수직으로 놓이게 할 수 있는 alignment 방법을 개발하였다. 파장에 대한 retardation 각도에서의 주기적인 진동의 모양은 alignment를 잘하게 되면 사라지게 된다. 또한 rotating compensator ellipsometer를 사용 할 때 넓은 분광영역에 걸친 retardation angle을 측정해 낼 수 있는 calibration 방법을 개발하였다.

신명수,김용재,배형석,백영진 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

유산균의 장내균총과 부패산물 생성에 미치는 영향을 알아보기 위하여, 건강한 성인 남녀 6명의 지원자에게 Lactobacillus acidophilus 와Bifidobacterium longum으로 제조한 유산균분말(각각 1.5×10 exp (9) cells)을 하루에 2회씩 2주동안 섭취하도록 하였다. 그리고 지원자 분변으로부터 균총수 변화와 부패산물인 암모니아, indole, skatole, p-cresole량을 측정하였다. 유산균의 투여 기간중에 분변내 bifidobacteria의 수가 8.78±0.39(log cfu/g feces±S.D)에서 9.27±0.29로 증가하였고(p<0.05) 투여 중지후에는 약간 감소하였으며, lactobacilli의 수는 6.15±0.80에서 6.76±0.48로 증가하였다(p<0.05). Enterococcus 균수는 투여 기간중에 6.66±0.80에서 7.72±0.40으로 증가하였다가 투여 중지후에는 감소하는 경향을 보였다. 그리고 혐기성균인 Bacteroides는 투여중에 8.45±0.34에서 9.15±0.21으로 증가하였으나(p<0.01), 유해균주로 알려진 Closridium(lecithinase negative)과 Staphylococcus 균수는 현저히 감소하였다. 그러나, 유산균 투여 실험기간인 6주 동안 분변내 암모니아, indole, skatole, p-cresole의 유의적인 농도변화는 없었다. To investigate the effects of lactic acid bacteria administration on fecal microflora and putrefactive metabolites in human being, Lactobacillus acidophilus and Bifidobacterium longum powder (1.5×10 exp (9) cells, respectively) was administrated to six healthy volunteers (average 28 years old) twice a day for 2 weeks. During the administration of lactic acid bacteria, the numbers of bifidobacteria, lactobacilli, and enterococci in feces were increased significantly, whereas those of Staphylococcus and lecithinase-negative Clostridium were decreased considerably. In addition, a number of anaerobic Bacteroides were increased. However, the contents of fecal ammonia and putrefactive metabolites (indole, skatole, p-cresole) were not changed during the administration.
