Polyphenol oxidase was partially purified from fresh vitis flexuosa and vitis amurensis and its characteristics were studied. the experimental results were summarized as follows. 1.The enzyme activities were increased during the fruit developement gradually in two sample. 2.The optimum pH and temperature for activity were 5.5 and 30℃, respectively. 3.The enzyme was active with o-phenols and trihydroxyphenol, but inactive toward m-diphenols and monophenols. 4.The ?? value of the enzymes was 15.4 mM in vitis flexuosa and 12.5 mM in vitis amurensis with catechol as substrate. 5.Inhibitors sudies indicated that sodium diethyl-dithiocarbamate, L-cysteine, sodium bisulfite, L-ascorbic acid and 2-mercaptoeyhanol were the most potent. 6.The enzyme activity increament by ?? was much better than those by the other metal ions.

침입탐지에서 지지율 기반 클러스터링을 이용한 정상행위 패턴 생성

오상현,장중혁 대구대학교 정보통신연구소 2010 情報通信硏究 Vol.7 No.1

For effectively detecting the intrusion through computers, many algorithms have been actively proposed so far, and recently the works related to anomaly detection, which is extended from misuse detection techniques by reducing their drawbacks, have attracted considerable attention since the anomaly detection technique can identify unknown intrusion methods. In this paper, a new clustering algorithm is proposed in order to extract patterns from the normal user activities. For the purpose, the anomalous user behaviors should be analyzed in various angles, and be classified by many different types of measures. 컴퓨터를 통한 침입을 효과적으로 탐지하기 위해서 많은 기법들이 제안되어 왔으며, 근래에는 오용 탐지 기법을 개선하기 위해서 비정상행위 탐지 기법에 관련된 연구들이 활발히 진행중이다. 본 논문에서는 침입탐지에서 정상행위 패턴을 생성하기 위해 지지율에 기반한 새로운 클러스터링 알고리즘을 제시한다. 이를 위해서 정상적인 사용에 대한 행위를 다양한 각도에서 분석될 수 있도록 여러 판정요소로 분류하고 각 판정요소에 대해서 제시된 알고리즘을 이용하여 정상행위 패턴을 생성한다.

수형자의 재판청구권과 변호인 접견권 보장 문제 : 최근 헌법재판소 결정례에 대한 분석을 중심으로

성중탁 梨花女子大學校 法學硏究所 2016 法學論集 Vol.21 No.2

A prisoner shall be subject to a number of fundamental rights as compared to the general public, but such restrictions shall be made only when necessary for the purpose of detention. Recently, the Constitutional Court made a constitutional unconstitutional and unconstitutional decision on the grounds that it infringed the right to a fair trial for the restriction of the time and the number of times in accordance with the general consultation when wearing a uniform and attorney at a criminal trial. The right to a fair trial is recognized as a fundamental right of prisoners in all countries of the world, and it is explicitly stipulated in the UN Covenant on Human Rights. However, the Constitutional Court considered that the right to fair trial was not infringed on civil justice in the civil trial, and the basic right of the prisoner was not recognized as the basic right of the prisoner. The problem with the current system, which depends on the type of trial, depends on the cases of developed countries where the apparel is widespread among the prisoners and the explicit rules in the UN Convention on the Rights of the People. In addition, in the case of reconsideration, which is a recent problem in relation to not accepting the prisoner's right to accept the lawyer's basic right as a constitutional right, the reason for the appeal must have credibility and persuasive power, And if it is blocked, it may infringe the right to a fair trial in that the reconsideration system itself may be pointless to the prisoner. Therefore, the discrimination between the two is extremely unfair in that both the detainee and the prisoner are subject to the right to a fair trial. In addition, foreign laws such as the United States, the United Kingdom, and the United Nations, as well as the United Nations Convention on the Rights of the Child, provide for the right to a fair trial, The current legislation stipulating should be urgently amended. 수형자는 일반 국민에 비하여 기본권 제한을 상당부분 받지만 그 제한은 구금 목적에 의해 필요한 경우에 한하여야 한다. 공정한 재판을 받을 권리와 변호인 접견권은 세계 각국에서 수형자의 기본권으로 인정되는 권리로 UN인권규약에도 이를 명시적으로 규정하고 있다. 이와 관련하여 최근 헌법재판소는 2012헌마858 결정에서 수형자가 변호인 접견시 일반접견에 준하여 시간과 횟수를 제한하는 규정에 대해 공정한 재판을 받을 권리가 침해되었다는 이유로 위헌결정을 하였다. 반면 2013헌마712 결정에서는 민사재판에서의 사복착용 불허조항의 경우 공정한 재판을 받을 권리를 침해하지 않는다고 보았다. 이를 규정하고 있는 현행 ‘형사소송법’이나 ‘형의 집행 및 수용자의 처우에 관한 법률’은 우리나라에도 적용되는 ‘시민적 및 정치적 권리에 관한 국제규약 및 그 선택의정서’와 ‘UN 피구금자 처우에 관한 최저기준 규칙’, ‘UN 피구금자 보호원칙’ 등의 취지를 잘 구현하지 못하고 있음에도 위 헌재 결정들은 이를 제대로 지적하지 못한 한계가 있다. 다만, 헌재 결정 중 형사재판에 출석하는 수형자의 사복 착용 금지 및 변호인접견의 횟수와 시간제한에 대해 위헌결정을 하였다는 점에서, 과거 결정들에 비해 수형자의 기본권 제한을 상당히 완화한 것은 고무적이다. 이는 주요 선진국이 수형자의 변호인 접견권, 재판청구권 등 기본권을 그 성질과 상황에 맞게 적절히 확대 보장하고 있는 추세와 그 궤를 같이 하는 것이다. 향후에는 관련 법 개정을 통해 재판의 종류와 관계없이 재판청구권 보장을 위해 수형자의 변호인 접견 및 사복착용의 범위를 기본권보장 관점에서 접근하여 미결수용자와 동일한 수준으로 보장함이 상당하다.

Objectives: To identify whether music therapy is effective for depression and quality of life (QOL) of patients with central nervous system (CNS) injury, using controlled comparison method. Methods: Twenty nine subjects with CNS injury assigned to one of the two groups, music therapy group (therapy group) or control group. Music therapy was applied to fifteen patients in the therapy group twice a week for 5 weeks (10 sessions) with daily physical and occupational therapy, while only physical and occupational therapy were applied to the control group routinely. Depression of all subjects was assessed by Beck depression inventory (BDI) and Hamiltonrating scale for depression (HRSD). QOL was measured with the use of the world health organization quality of life assessment instrument-brief (WHOQOL-BREF). Each evaluation was assessed at the beginning of this study and after 10 sessions’music therapy. Results: The mean BDI scores reduced in the two groups, but the differences were not significant. In the therapy group, the mean score of HRSD was reduced significantly after song psychotherapy for 5 weeks, from 7.6±5.6 to 3.5±4.1 (p<0.05), while it was not significantly reduced in the control group. The mean scores of WHOQOL-BREF in the therapy group were advanced in every domain. In the control group the mean score of social relationships domain was worsen after 5 weeks comparing the mean score at the beginning of this study. Conclusions : The music therapy relieves patients with CNS injury from depression, and it also seems to be able to improve QOL of them.

황성필,김무준,하강열,강갑중 한국센서학회 2002 센서학회지 Vol.11 No.3

본 연구에서는 온도에 따른 압전특성이 매우 안정적인 LiTaO_3(x-112°y) 단결정을 이용하여 압전변압기를 제작하고 그 특성을 분석하였다. 제작시 LiTaO_3 단결정의 변환효율이 낮은 단점을 보완하기 위해 Lame'-mode를 이용하여 길이와 폭의 비가 2:1인 압전변압기를 제작하고 PSpice를 이용하여 진동 모드 해석, 입력전압에 따른 출력전압특성 및 진동속도특성을 분석하였다. 제작한 압전변압기는 길이방향의 제 2차 고조파 주파수와 폭방향의 기본공진주파수가 결합된 290.83(㎑)에서 입력전압에 대한 최대출력전압이 나타났으며, 약 10배 정도의 승압비를 얻을 수 있었다. The single crystal of LiTaO_3(x-112°y) has very stable thermal characteristics in a piezoelectric transformer. In this paper, a piezoelectric transformer made of the crystal is newly designed and its operating characteristics are analyzed. The length of the transformer is determined as twice as its width for Lame'-mode because the single crystal of LiTaO_3 has low electro-acoustic efficiency. The electric and vibrational characteristics of the transformer is simulated by the PSpice program, and its results are compared to experimental ones. As the results, the ratio of output voltage to input shows large than 10 at 290.83(㎑), which is the frequency coupled the 2nd harmonic for length and the fundamental for width of the Lame'-mode transformer.

Myosin, the major protein required for the production of force and shortening in muscle, is a hexamer consisting two heavy chains (molecular mass∼200kDa) and pairs of light chains (molecular mass∼16 and 20kDa). Myosin and other contractile apparates from the left ventricular myocardium of rabbit were extracted using pyrophospate buffer system and was purified by using the gel filtration. And partially purified each protein component was confirmed by the electrophoresis in non-dissociation and dissociating conditions respectively. On Disc-PAGE of the crude extract, 4 bands clearly appeared and 3 protein components were separated by chromatography in the 5 fractions. In dissociating electrophoresis, each bands were separated into subunit in the pyrophosphate buffer. The first fraction contained the heavy chain of myosin, tropomyosin and myosin light chain 1 and 2. The second and third fraction were composed of tropomyosin and actin and the proteins that had molecular mass smaller than 15kDa were in the fourth and fifith fractions.

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.
