Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

연구목적: 팀티칭에 근거한 통합강의는 최근 대부분의 의과대학에서 시행되는 강의형태이다. 그러나 기 존에 사용되고 있는 온라인 강의평가 방식은 이러한 강의 특성에서 나타나는 문제점을 파악하기 힘든 점이 있다. 본 대학에서는 팀티칭에 의한 통합강의에서 문제강의를 직접적으로 파악하는 ‘문제강의 직 접평가지’를 개발하였다. 본 연구의 목적은 새로이 개발된 문제강의 직접평가지가 강의개선에 끼친 영 향력을 알아보고자 하는 것이었다. 연구방법: 2007년 2학기부터 2009년 2학기까지 충북대학교 의과대학 1, 2학년을 대상으로 문제강의 직접평가지에 의한 강의평가를 실시하였다. 평가지 질문 중에서 두 가지 객관식 질문에 대한 답변을 분 석대상으로 선택하였다. 질문은 첫째, ‘가장 유익하고 도움이 많이 되었던 강의들은 무엇입니까?’와 둘 째, ‘가장 어렵거나 이해하기 힘들었던 강의들은 무엇입니까?’였다. 강의평가를 실시한 강좌들 중에서 2 년 이상 연속적으로 강좌구조와 평가지의 객관식 질문 형식이 변하지 않은 14개의 강좌를 분석대상으로 하였다. 각각 연도의 평균 긍정비율을 다른 연도의 것과 카이제곱 검정 방법을 사용하여 비교하였다. 결과: 14개의 강좌 중에서 시작연도와 마침 연도 간에 긍정비율이 증가된 경우는 13개 강좌였다. 그 러나 통계적으로 의미가 있는 경우는 5개 강좌에서 나타났다. 결론: 문제강의 직접평가지에 의한 문제강의를 판별해 내는 방법은 단기간에 통합강좌의 개선에 효과 적이다.

The present study was attempted to investigate the cardiovascular effects of Cheonmagudeumg-Eum (CMGDE), which is known to be one of chinese medical prescriptions used in treatment of hypertension, in the anesthetized rats and to clarify the mechanism of its pharmacological action, making use of its water extract. 1. CMGDE (5-45 ㎎/㎏), given into a femoral vein of the rat, produced a dose-dependent hypotensive and bradycardic responses while even much larger doses of it (10-90 ㎎/㎏), given into the rectum, did induced negligible hypotensive responses. 2. CMGDE-induced depressor responses were inhibited greatly by pretreatment with phentolamine (an adrenergic α-receptor antagonist), but not by pretreatment with atropine (an antimuscarinic agent) and chlorisondamine (an autonomic ganglionic blocker). 3. Pressor responses evoked by intravenous norepinephrine were attenuated significantly by pretreatment of CMGDE-infusion with a rate of 45㎎/㎏/20min. 4. In the rat aortic strips, phenylephrine (an adrenergic α1-receptor agonist) and high potassium (a membrane depolarizing agent) caused potent contractile responses, respectively. However, in the presence of CMGDE (2㎎/㎖), the contractile responses of phenylephrine (10-5M) and high potassium (5.6×10 exp (-2)M) were markedly inhibited. Taken together, these experimental results suggest strongly that Cheonmagudeung-Eum may cause the hypotensive responses in the anesthetized normotensive rat, indicating that this cardiovascular effects of CMGDE is likely due to the blockade of adrenergic α-receptors without cholinergic effects.

To investigate transcriptional regulation of iNOS gene by LPS and cytokines, the production of NO, expression of iNOS mRNA and protein, binding activity of nuclear factor-kappa B(NF-kB), and promoter activity of iNOS gene were examined in rat C6 glial cells. LPS, interferon-gamma(IFN-γ), and tumor necrosis factor-alpha (TNF-α) stimulated the production of NO, which was increased synergistically by co-treatment. By the treatment of LPS, iNOS mRNA expression was initiated at 1 h, markedly increased by 3 h, and decreased gradually afterward. iNOS mRNA expression was markedly enhanced by mixture of LPS, IFN-γ and TNF-α. iNOS protein synthesis was increased by the treatment of mixture LPS and cytokine mixture. Treatment of LPS stimulated NF-kB activation, and the activation reached to the maximum level at 30 min, and the treatment of mixture of LPS and cytokines increased the activation. To determine the effect of NF-kB binding activity on iNOS promoter activation, CAT assay was performed. iNOS promoter activity was increased by the treatment with LPS for 5.5 h, and further increased by the combined treatment with LPS and cytokines. These results suggest that NF-kB activation by LPS and cytokines may play a significant role in the induction of the iNOS gene.

This paper proposes a new adaptive algorithm to improve the robustness and performance of the adaptive control systems. This adaptive algorithm counteracts the effects of disturbances and makes the time derivative of Lyapunov function non-positive, V≤0. As a result, the output error approaches zero as t → ∞ not only in the presence of bounded disturbances, but ideal case. Computer simulation results are presented to show the effectiveness of the proposed algorithm.

이재봉,배석찬,이홍로,이연식 群山大學校 1993 論文集 Vol.20 No.-

객체 지향 데이타 모델을 지원하는 데이타베이스 시스템은 기존의 데이타베이스의 단점을 보완하며, 다양하고 복잡한 실세계의 정보를 처리할 수 있다. 객체 지향 데이타베이스 시스템은 사용자의 접근을 위해 질의 및 객체 관리 인터페이스를 필요로 한다. 본 논문에서는 사용자를 위한 질의 인터페이스와 질의 계획을 수행하기 위한 객체 관리 인터페이스를 설계함으로써 질의 목적을 달성토록 하였다. 설계된 객체 관리 인터페이스는 응용을 위해 "C"언어 함수로 구성하였고, 성능 항상을 위한 확장성을 제공할 수 있도록 설계 하였다. The database system that supports object oriented data model can complements conventional DBMS's drawbacks and processes complex and intensive applications. In object oriented database system, the access and management of all objects are manipulated by object manager. Therefore, a query interface as well as an Object Manager Interface(OMI) is required for interfacing between a user and an object store. In this paper, we propose the query interface which can support object oriented paradigm and design rules of OMI, and implement OMI based on the rules. The OMI have been implemented by using C language on UNIX OS machine.

Pap smear were performed to 30,294 women living in the north-west of Chung-nam. The result are summarized below 1. Positive vaginal cytology was 1.09 percent. 2. 72 percents women in their 30's and 40's experienced vaginal cytology. 3. Vaginal cytology was performed at a decreasing rate as age increases. 4. Positive cytology rate is 2.42% higher than average for elderly women over the age of 65. The present date indicates that pap smear is being widely recognized to be important but they needs to be continued advocacy for pap smear.
