우리나라에는 Cambro-Ordovician기의 조선누층군에 속하는 석회암지층이 널리 분포하고 있으며 소규모나마 이들 지역에 Shinkhole terrain이 발달하므로 본 논문은 고도가 상이한 3개지역에서 발달하는 Sinkhole terrain을 비교하여 그 특성을 구명하는데 있다. 본 연구지역은 강원도지역중 Sinkhole terrain이 비교적 잘 발달되고 고도가 상이한 3개지역을 선정하였다. 즉 100m 이하의 삭박면인 북평-삼척 지역과 300-600m 삭박면의 정선군 회동리와 600-900m 삭박면의 정선군 백복령일대이다.

문서 표절이 사회적으로 이슈가 됨에 따라 표절 문서를 판별할 수 있는 시스템의 필요성이 대두되었다. 문서 표절 검사 시스템에서 가장 중요한 이슈는 성능과 속도인데 이 두 가지를 모두 만족시키기 위해서는 표절을 상세하게 검사하기 전에 표절 의심 문서에 대한 비교 문서군이 크기를 최적화하여 표절 검사 범위를 최대한 작게 만들어야 한다. 비교 문서군의 크기를 최적화하기 위해서는 표절 의심 문서와 상관이 없는 문서를 필터링 하는 작업이 필요하다. 이 논문에서는 문서를 빠르게 필터링 하기 위해서 웹 문서 검색에 사용되는 Inverted Index을 이용하여 적당한 시간 안에 비교 문서군의 크기를 최적화 하는 방법들을 알아보고 각각의 방법들의 성능을 비교 분석하는 방법을 제시하며 그 방법들을 바탕으로 성능을 분석하여 최적화된 문서 필터링 방법을 알아본다.

본 연구는 흑삼의 항당뇨 효과를 알아보고자 4그룹(정상군, 당뇨 쥐, 당뇨 쥐에게 백삼을 투여한 군, 당뇨 쥐에게 흑삼을 투여한 군)으로 나누어 6주간 실시하였다. 6주 후 식품섭취량, 체중 증가량을 비교하였는데, 식품섭취량, 체중 증가량에는 그룹 간에 유의적인 차이가 나타나지 않았으나, OGTT(oral glucose tolerance test)와 IPITT(intraperitoneal insulin tolerance test) 경우는 흑삼 투여군에서 긍정적인 결과를 나타내었다. 또한 혈청 포도당과 인슐린농도에 미친 영향을 비교, 분석한 결과, 흑삼 투여군에서 공복 시 혈당, 혈청 포도당, 인슐린 농도가 유의적으로 감소하였다. 이 결과를 미루어 볼 때 흑삼이 백삼에 비해 당뇨를 치료하는데 더 효과적일 것으로 판단된다.

Objectives : "Alexithymia" mean literally "no word for mood(or emotion)". It is not only a marked constriction in emotional functioning but a deficit in their cognitive processing. We designed this study to investigate the level of alexithymia, psychopathology and personality factors of patients with somatoform disorder and with diabetes mellitus. Methods : The subjects were consisted of patients with somatoform disorder(N=20), patients with diabetes mellitus(N=20), and normal control(N=20). The level of alexithymia, psychopathology and personality factors were assessed by the Toronto Alexithymia Scale(TAS), the Symptom Checklist 90-Revision(SCL 90-R), and the Sixteen Personality Factor Questionnaire(16-PF). And we compared demographic characteristics, psychopathology and personality factors among three groups, and assessed the relationship between alexithymia and psychopathology, and between alexithymia and personality factors. Results : The results were as follows. 1) Patients with somatoform disorder showed significantly higher TAS scores compared to patients with diabetes mellitus and the normal control group. 2) Patients With somatoform disorder showed significantly higher scores of somatization, anxiety scales than patients with diabetes mellitus and the normal control group, and showed significantly higher scores of obsessive-compulsive, depression, phobic anxiety, psychoticism scales than the normal control group by the SCL-90-R. 3) The normal control group showed high intelligence scores only as compared to patients with somatoform disorder by the 16-PF. 4) A significant relationship was found between TAS scores and psychopathology in patients with somatoform disorder. 5) All three groups did not shown any correlation between TAS and 16-PF. Conclusion : Patients with somatoform disorder showed higher TAS scores and more multiple psychopathology than patients with diabetes mellitus and the normal controls. A significant relationship was found between TAS scores and psychopathology in patients with somatoform disorder. We suggest that the therapeutic approach to patients with somatoform disorder to express emotions and manage psychopathology, and that the treatment methods of patients with diabetes mellitus aims to improve firstly physical conditions are more helpful.

The donor pool for heart transplants is severely limited and there is still a legal problem of brain death. This study assessed the function of hearts "absolute anoxic" for ten minutes after asphyxia by perfusing the hearts on a Langendorfr apparatus for 45 minutes with Krebs-Henseleit buffier at 37 t at 80 cm H2O. Forty isolated rat hearts were divided into four groups. Ten control hearts (group 1) were perfused on the circuit without intervening ischemia. Ten hearts (group 2) were harvested, quickly flushed with 5cc of cold University of Wisconsin solution, and stored in the same cold solution for 4 hours. Ten hearts (group 3) were excised, quickly flushed with 5 u of cold Stanford cardioplegic solution and stored in cold saline solution for 4 hours. Ten asphyxiated hearts (group 4) had warm ischemia for ten minutes and were perfused with 5u of cold Stanford cardioplegia containing 7,500 units of urokinase to dissolve intravascular clots, and stored in cold saline solution for 1.5 hours. Time of spontaneous defibrillation (TSD) after perfusion was significantly longer in group 2, group 3 and group 4 than in group 1. TSD in group 3 and group 4 was significantly longer in comparison to that of group 2. Left ventricular developed pressure(LVDP) at 15 minutes was significantly lower in group 3 and group 4 than in group 1 and group 2. In group 4, LVDP at 30 minutes and 45 minutes was significantly lower compared with that in group 1 . In conclusion, asphyxiated rat hear;ts which had absolute anoxia for 10 minutes after as hyxia showed relatively satisfactory cardiac function. function.

In this study, we evaluated the effectiveness of a taping method to relieve low back pain (LBP) by comparing changes in visual analog scale (VAS) and disability index (Disa) between untreated, control, and treated groups. As a result, the efficacy of taping was confirmed in both the control and treatment groups. ANOVA analysis of VAS revealed significant differences between groups, and post hoc tests revealed significant differences in the untreated group and both the control and treatment groups, but no significant differences between the control and treatment groups. This demonstrates similar effectiveness of both taping methods on alleviating LBP. For Disa, ANOVA showed a significant difference, but post hoc tests did not confirm this. The within-group t-test showed significant differences in VAS and Disa in the control and treatment groups before and after the intervention, but not in the untreated group. This study highlights the efficacy of taping for LBP and suggests that both methods can be used clinically. Future studies should use larger samples and different conditions to verify these findings.

이 연구의 목적은 Motor-Free Visual Perception Test (MVPT)와 Mariannene Frostig Developmental Test of Visual Perception (DTVP)을 사용하여 뇌성마비 아동과 정상아동의 시 지각 능력의 차이를 알아보고, 뇌성마비의 사지마비군과 양하지마비군, 그리고 정상아동군에서 두 평가도구의 결과에서 제시한 시 지각능력의 차이를 비교하기 위한 것이다. 뇌성마비 아동 21명(사지마비 11명, 양하지마비 10명)과 정상아동 8명을 대상으로 하였다. 대상의 연령범위는 4세에서 8.5세이었다. 시 지각 능력을 평가하기 위하여 운동기능을 포함하지 않은 MVPT와 운동기능을 포함한 DTVT를 사용하였다. 평가과정과 방법은 표준화된 지침서에 따라 수행하였다. 자료분석은 SPSS를 사용하여 Wilcoxon signed rank test와 Mann-Whitney, Kruskal-Wallis를 하였다. MVPT와 DTVP의 지각지수를 뇌성마비 아동과 정상아동을 비교한 결과 뇌성마비 아동의 지각지수가 정상 아동보다 유의하게 낮았다. 아동의 교정연령과 MVPT와 DTVP의 지각연령의 차(CA-PA)를 사지마비군, 양하지마비군, 그리고 정상군과 비교한 결과 정상군에서는 두 평가도구 간의 차이가 없었으나, 사지마비군에서는 두 평가도구 사이에 유의한 차이가 있었다. 이 연구의 결과는 뇌성마비 아동의 시 지각능력을 평가하기 위한 도구로 MVPT의 사용을 제시하였다.

Background: Adenosine is secreted by myocardial cells during myocardial ischemia or hypoxia. It has many beneficial effects on arrhythmias, myocardial ischemia, and reperfusion ischemia. Although many investigators have demonstrated that cardioplegia that includes adenosine shows protective effects in myocardial ischemia or reperfusion injury, reports of the optimal dose of adenosine in cardioplegic solutions vary. We reported the results of beneficial effects of single dosage(0.75 mg/Kg/min) adenosine by use of self-made Langendorff system. But it is uncertain that dosage was optimal. The objective of this study is to determine the optimal dose of adenosine in cardioplegic solutions. Material and Method: We used a self-made Langendorff system to evaluate the myocardial protective effect. Isolated rat hearts were subjected to 90 minutes of deep hypothermic arrest(15$^{\circ}C$) with modified St. Thomas' Hospital cardioplegia including adenosine. Myocardial adenosine levels were augmented during ischemia by providing exogenous adenosine in the cardioplegia. Three groups of hearts were studied: (1) group 1 (n=10) : adenosine - 0.5 mg/Kg/min, (2) group 2(n=10): adenosine -0.75 mg/Kg/min, (3) group 3 (n=10) : adenosine -1 mg/Kg/min. Result: Group 3 resulted in a significantly rapid arrest time of the heart beat(p<0.05) but significantly slow recovery time of the heart beat after reperfusion(p<0.05) compared to groups 1 and 2. Group 2 showed a better percentage of recovery(p<0.05) in systolic aortic pressure, aortic overflow volume, coronary flow volume, and cardiac output compared to groups 1 and 3. Group 1 showed a a better percentage of recovery(p<0.05) in the heart rate compared to the others. In biochemical study of drained reperfusates, CPK and lactic acid levels did not show significant differences in all of the groups. Conclusion: We concluded that group 2 [adenosine(0.75 mg/Kg/min) added to cardioplegia] has better recovery effects after reperfusion in myocardial ischemia and is the most appropriate dosage compared to group 1 and 3.
