This study analyzed the hydromechanical behaviors of hydraulic and natural fractures caused by fluid injection, such as fracture closing-reopening and the related pressure parameters, stress mechanism changes, slippage-dilation criterion of natural fracture, and complex fracture intersections. When hydraulic and natural fractures intersect, the conditions for crossing, slippage, and dilation depend on intersection angles between fracture and stress direction, differential stress, and mechanical properties such as cohesion and friction coefficient of the fractures. Micro-mechanical and quantitative assessment technologies should be further developed for the analyses of fluid-fracture dynamics and the induced seismicity-like phenomenon. 지하 암반 내 유체 주입에 의한 수압파쇄 균열과 자연 균열의 수리역학적 거동과 관련하여균열 개폐와 압력 변수 관계, 응력 메카니즘 변화, 자연 균열의 미끄러짐-팽창 기준, 복합균열 교차 전파 등의 관계를 분석하였다. 자연 균열면의 열림 상태에 따라 균열 거동과 관련한 압력 변수 및 응력해석해 적용의 유효성에 차이가 있었다. 수압파쇄 균열과 자연 균열의 교차시에 수압파쇄 균열의 자연 균열 관통, 자연 균열의 미끄러짐 또는 팽창 열림 등의기준은 두 균열의 교차각, 주응력 방향과의 교차각, 주응력의 차, 균열면의 역학적 특성인점착력과 마찰계수 등에 의해 좌우된 다. 이러한 유체-불연속면 동역학적 거동 및 때로 수반되는 지진동 같은 현상의 관계 규명에는 미시역학적이고 정량 적인 연구와 평가기법 개발이 있어야 한다.

Interactive computer-aided analysis of mechanical systems has recently been undergoing an evolution due to highly efficient computer graphics. The industrial implementation of state-of-the-art analytical developments in mechanisms has been facilitated by computer-aided design packages because these rigid-body mechanism analysis programs dramatically reduce the time required for linkage design. This paper proposes a component modular approach to computeraided kinematic motion analysis for general planar multiloop mechanisms. Most multiloop mechanisms can be decomposed into serveral components. The kinematic properties (position, velocity, and acceleration) of every node can then be determined from the kinematic analysis of the corresponding component modules by a closed-form solution procedure. In this paper, 8 types of modules are defined and formulations for kinematic analysis of the component modules are derived. Then a computer-aided kinematic analysis program is developed using the proposed approach and the solution procedure of an example shows the effectiveness and accuracy on the approach.
Study on Profile Generation of Conjugate Plate Cams for a Roller Gear Cam Mechanism
신중호,Ho-EopYoon,YuhuaZhang 한국정밀공학회 2002 International Journal of Precision Engineering and Vol.3 No.3
A roller gear cam mechanism is presented. It consists of two or more plate cams with particular teeth, called Conjugate Cam Tooth (CCT) and a turret with axially located rollers. A practical and available configuration has been found out by synthesizing its parameters. The profile equations of the conjugate cam are derived by using a relative velocity method. A program for the design automation of shape of the conjugate cam and the motion simulation of this kind of mechanism has been developed using the derived formulae with C++ language. Finally, an example is given.

Purpose: This study analyzed the value of ^(99m)Tc-MIBI SPECT(Single Photon Emission Com-puted Tomography) in the deagnosis of myocardial contusion after blunt chest trauma. Methods: We evaluated 24 patients with cardiac contusions after blunt chest trauma who were diagnosed by clinical symptoms, chest x-ray, electrocardiogram(ECG), and Creatine phospho-kinase(CPK). ^(99m)Tc-MIBI SPECT was performed within 48 hours along with the above tests prospectively. Results: 1. Among the 24 patients, 14 patients were finally diagnosed as having a myocardial contusion by means of ECG, echocardiography, (^99m)Tc-MIBI SPECT, and cardiac enzyme. 2. The sensitivity, specificity and accuracy of ^(99m)Tc-MIBI SPECT were 46.7%, 66.7%, and 54.2%, respectively. The same results for initial ECG were 46.6%, 88.9%, and 62.5%. 3. For those who had positive findings in ^(99m)Tc-MIBI SPECT, average hospital stay was 14.5 days and abnormal electrocardiogram was found in 90.0%. However, for those who had negative findings, average hospital stay was 11.2 days and abnormal electrocardiogram was found in 35.7%. Conclusion: ^(99m)Tc-MIBI SPECT is not a definite modality in diagnosing myocardial contusion, but can be useful in diagnosing and determining the need for hospitalization after cardiac contusion.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.
