Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

Purpose: The aim of this study was to evaluate the normal values of regional cerebral blood flow (rCBF) and cerebrovascular reserve (CVR) in normal children to aged volunteers using Tc-99m HMPAO. Materials and Methods: Thirty four right-handed normal volunteers (20 males, 14 females, mean age 40.3±24.9 years, range 4 to 82 years) were underwent rest/acetazolamide (ACZ) brain SPECT using Tc-99m HMPAO and the sequential injection and subtraction method. rCBF was estimated on the basis of a semiquantitative approach by means of right/left ratio, region/cerebellum and region to whole brain ratios in frontal, parietal, temporal, and occipital lobes, basal ganglia, thalami, and cerebellum. CVR was measured by means of % perfusion increase calculated as % mean count change compared to rest rCBF in each regions. Results: Mean values of right to left ratios range from 1.004 to 1.018. rCBF was highest in cerebellum and lowest in basal ganglia and thalami. Frontal and temporal rCBF decreased while occipital and thalami rCBF increased according to age. No sexual difference of rCBF was noted. Mean CVR was 29.9±12.9%. Mean CVR significantly increased to late teens, and declined thereafter. After 6th decade, CVR in both frontal lobes, left parietal lobe and right basal ganglia decreased significantly with advancing age. There was no sexual difference of CVR. Conclusion: Quantitative assessment of CVR was possible by ACZ Tc-99m HMPAO brain SPECT. It revealed that rCBF and CVR changed according to age in normal Korean volunteers. There was no sexual difference.

Objective : To estimate the angiogenic effect of water extract of Cnidii Rhizoma (ECR), we employed the rat sponge model for angiogenesis. Methods : It was based on subcutaneous implantation of sterile polyester sponges in the SD rat and we have characterized the dye method that incorporates 5% carmine red and 1% cresyl violet in 10% gelatin. vascularity index (V.I.) expressed as ㎍ dye/mg tissue. Subcutaneous implantation of sterile polyester sponges in SD rats enhanced the neovascularization over 14 days, as determined by measurements of relative sponge blood flow by a vascularity technique. The angiogenic response was verified by histological evaluation of vascularized sponges. Results : Daily oral administration of ECR (100 mg/kg for 14 days) produce no apparent effect on angiogenesis. The vasoconstrictor peptide, angiotensin Ⅱ (AⅡ), in daily doses of 100 nmol, caused an intense neovascularization but lower doses of AⅡ produced no apparent effect (1 nmol and 10 nmol). Co-administration of 100 nmol AⅡ and 100 mg/kg ECR p.o. depressed 100 nmol AⅡ-induced angiogenic effect. Conclusion : We have shown that p.o. daministration of 100 nmol AⅡ accelerated angiogenesis. Meanwhile, co-administration of 100 nmol AⅡ and 100 mg/kg ECR highly suppressed angiogenic property.

거대고리 리간드는 금속이온과 선택적으로 결합하는데, 이를 이용하여 에멀젼 액체막을 통한 금속이온의 이동에 관하여 연구를 수행하였다. 금속이온은 유기층에 있는 운반체에 의하여 source phase에서 receiving phase으로 이동한다. 운반체로는 거대고리 리간드인 DBN_(3)O_(3)를 사용하였다. 여기에서 에멀젼 액체막을 통한 금속이온의 이동에 관한 요인과 어떤 금속이온의 선택적 분리에 관하여 검토하였다. 금속이온과 거대고리 리간드 그리고 금속이온과 receiving phase내에 있는 음이온에 대한 안정도 상수를 금속이온의 선택적 이동에 대한 척도로 조사하였다. 납이온이 혼합 용액에서 다른 금속이온보다 높은 이동속도를 나타내었다. Receiving phase내의 음이온이 금속이온의 이동에 중요한 역할을 한다. Receiving phase내에 있는 NO_(3)^(-)을 S_(2)O_(3)^(2-) 대치하면 이동량이 증가함을 보였는데 이는 Pb^(2-)-S_(2)O_(3)^(2-) 상호작용이 Pb^(2+)-NO_(3)^(-) 상호작용보다 크기 때문이다. Macrocyclic ligand has been know to selectively bind with metal ions so that ability applied for the transport of metal ions across the emulsion liquid membrane in this study. The metal ions are transproted from the source phase to the receiving phase by the carrier of the organic phase. Several factors involved in the transport of metal ions acrose the emulsion membrane we reported here and these factors proveided the informations for the selective seperation of some metal ion. Stability constants for cation-macrocyclic ligand and metal ion-anion receiving phase interaction are examined as parameters for the prediction of metal ion transport selectivities Pb^(2+) was transported higher rates than the other metal ions in the mixture solution. The interaction of metal ion to anion in receiving phase is important. S_(2)O_(3)^(2-) in replacement of NO_(3)^(-) in the receiving phase enhances the transport of pb^(2-) since Pb^(2-)-S_(2)O_(3)^(2-) interaction is greater than Pb^(2+)-NO_(3)^(+) interaction.

First, in terms of a time continuum, it provides meaning which dynamical time spirit and time continuity in the form of irregular architecture considering with that the present state of the connection from the past memory of environmental landscape and regenerative function. Second, in terms of this study it was determined, that the time continuum or flow as it relates to architecture on this study was that it was found that as this time continuum when it relates to human senses, and human life in generals negates, any reference to Einstein both theory of simultaneity, as it relates to urban space and architecture form by both in terms of this study, movement and time continuum.

二重課稅 問題에 대한 硏究 : 국제조세상 이중과세조정문제를 중심으로

정문현,이환근 釜山 大學校 經營 經濟 硏究所 1996 經營 經濟 硏究 Vol.15 No.1

본 논문은 이중과세문제를 국내이중과세와 국제이중과세의 두 가지 형태로 나누어서 검토하고 있다. 합리적인 세무계획과 효율적인 세무관리는 기업의 국제경쟁력을 결정하는 중요한 요인 중의 하나이므로 기업은 물론 세무당국도 급변하는 조세환경에 능동적으로 대처해 나갈 수 있어야 할 것이다. OECD 가입 등 가속화되고 있는 개방경제에서 이중과세문제는 이제 통합된 분석시각에서 접근되어야 할 필요가 있다. 따라서 본 논문에서는 주로 국제공간에서 야기되는 이중과세문제에 중점을 두고 있지만 이들 두 가지 이중과세문제를 동일 평면상에서 분서고하고 있다. 연구결과 첫째, 영세규모의 사업이 아니라면 법인기업의 조세부담율이 개인기업형태로 운영된 사업소득에 비해 오히려 세부담이 낮다는 기존 주장은 추가적인 연구에 의해 재검증되어야 할 것으로 나타났다. 둘째, 개인출자자의 경우는 배당세액공제가 허용되며 내국법인이 해외자회사로부터 수취하는 배당에 대해서는 간접외국세액공제가 인정되고 있지만 내국법인이 다른 내국법인으로부터 수취하는 배당에 대해서는 이중과세를 배제하기 위한 아무런 조치가 마련되어 있지 않았다. 세째, 누진부면제방법에 한정해 보면 모델조약규정은 누진부면제방식을 권장하고 있지만 우리 법인세법에서는 소득금액계산시 외국법인세액을 손금에 산입하는 형식을 취하고 있어서 모델조약규정과 상치되고 있다. 네째, 자국의 과세권 확보 차원에서 국내법을 오히려 조세조약에 우선시키려는 움직임들이 있는 것으로 이해되었다. 이러한 결과는 후속연구에 의해 더 자세히 분석되어야 할 필요가 있지만 개방경제하에서 이중과세문제가 어떻게 접근되어야 할 것 인가에 대해 몇가지 시사점을 제시하고 있다.

정혜경,곽재진,유민아,배기선,권정미,이종수,김도영,문일환 대한감염학회 2003 감염과 화학요법 Vol.35 No.3

목적 : 본 연구는 Helicobacter pylori (이하 H. polyri) 양성인 소화성 궤양 환자에서 lansoprazole 포함 삼제요법의 제균율을 알아보고, 제균 치료 후 제균 판정에 있어서 요소 호기 검사(Urea breath test, 이하 UBT) 및 신속요소분해(rapid urease test, 이하 RUT test)와의 일치율에 대하여 알아보고자 하였다. 방법 : 상부위장관내시경 검사에서 H. polyri 양성인 소화성 궤양환자에서 lansoprazole 60㎎+amoxicillin 2g+clarithromycin 1g의 약제를 2회 분복하여 1주간 복용하는 삼제요법을 실시하였다. 최소 4주후 추적 상부위장관내시경을 실시하였고, 전정부와 체부에서 각각 RUT를 실시하였으며 UBT(5분, 20분)를 시행하였다. 결과 : 대상환자는 총 46명으로 남자 34명(48±13세), 여자 12명(53±14세)이었다. LAC 삼제요법의 제균율은 40/46명(87.0%)이었고, 궤양의 치유율도 42/46명(91.3%)이었다. RUT와 20분 UBT 결과가 모두 음성이었던 경우는 41예, 모두 양성이었던 경우는 4예로 RUT와 UBT는 97.8% (45/46)의 일치율을 보였고, 1예는 UBT는 음성이었으나 체부에서 시행한 RUT가 양성이었다. 5분 UBT 검사가 양성이었던 예는 14/34 (41.2%) 이었고, 이 14예 중 12예(85.7%)는 20분 UBT 검사 음성, RUT 음성이었다. 결론 : Lansoprazole과 amoxicillin, clarithromycin 1주일 병합요법은 H. polyri 양성인 소화성 궤양 환자에서 87.0%의 제균율을 나타내어 우수한 효과를 보였고, 요소호기검사는 제균 치료 후 제균 판정에 유용한 비침습적인 방법임을 확인할 수 있었다. Background : There are only a few studies on Helicobacter pylori (H. pylori) for its eradication rates of lansoprazole-based triple therapy in Korea, and the results are controversial. Therefore, we undertook to investigate the eradication rate of lansoprazole-based triple therapy, and compare the concordance rate of urea breath test (UBT) and rapid urease test (RUT) in evaluating H. pylori eradication. Methods : Patients with acute peptic ulcer who were H. pylori-positive were recruited by prospective, consecutive manner. They received lansoprazole 30 ㎎ b.d., amoxicillin 1 g b.d. and clarithromycin 500 ㎎ b.d. for 1 week. Upper endoscopy was performed after 4 weeks to check for ulcer healing, and UBT and RUT were performed to evaluate H. pylori eradication status. Results : A total of 46 patients were recruited, and they were all compliant. H. pylori eradication rate was 87.0% (40/46) and ulcer healing rate was 91.3% (42/46). Forty one patients showed negative in both UBT and RUT, and 4 patients revealed positive in both tests, therefore, the concordance rate of UBT and RUT was 97.8% (45/46). Conclusion : Our study showed that 1-week lansoprazole-based triple therapy was effective in H. pylori eradication and ulcer healing. UBT can be an effective, noninvasive method for evaluating H. pylori status after H. pylori eradication.

정용환,한상현,오유성,고미희,고석찬,김문홍,오문유 濟州大學校 基礎科學硏究所 2001 基礎科學硏究 Vol.14 No.2

We analyzed the genetic variation and phylogenetic relationship among fourteen taxa of GenusAbies distributed in Korea using random amplified polymorphic DNA (RAPD) and internal transcribed spacer (ITS) 2 sequences of the nuclear ribosomal DNA (rDNA). RAPDs were used for identification of selected taxa by amplification using single 10-mer primers of arbitrary sequence. Fourteen taxa were clearly classified with 10 arbitrary primers, which generated 102 useful polymorphic bands that were evaluated according to the presence or absence of the fragments of equal size. The genetic distance between A. koreana for. chlorocarpa and A. koreana for. rubrocarpa was 0.127, showing the closest among any other pairs. By comparing the base sequences in the ITS2 region of the nuclear rDNA, genetic relationship was assesed among selected taxa. It showed twenty six sites of point mutation (base substitution) in 243 base pairs (bp) of ITS2 region. The G+C contents of ITS2 region were ranged from 58.3% to 61.7%. The value of nucleotide divergence among selected taxa was ranged from 0.4% to 9.8%. These results showed that RAPD and ITS2 sequence analysis was a useful tool for elucidating phylogenetic relationship and selection of specific marker in Abies species.
