활막성 연골종증은 비교적 드문 양성 종양으로 관절내 활액막 결체조직의 양성 반응성 이형성에 의해 여러 개의 연골성 결절을 형성하고 이것이 관절내로 유리되어 유리체를 형성하는 질환으로 주로 슬관절에 발생한다. 활막성 연골종증의 정확한 발생 기전은 아직 밝혀지지 않았으나 외상, 감염 등이 원인으로 제시되고 있다. 저자들은 슬관절 내 히야루론산 주입후 발생한 슬관절내 활막성 연골종증을 1 례 경험하였으며, 관절경적 제거술을 통해 만족스런 결과를 얻었다. As a relatively rare benign tumor, synovial chondromatosis forms several cartilaginous nodules by the benign reactive metaplasia of synovial connective tissues within joints, which are loosed into the joints and cause a disease forming loose body mainly in knee joint. Accurate mechanism of synovial chondromatosis has not been clarified yet; however, trauma, infections and others have been suggested as its possible causes. The authors of this study experienced an example of a patient with synovial chondromatosis in knee joint occurred after the injection of hyaluronic acid in the joints and had a satisfactory outcome through the arthroscopic resection.

This paper discusses a real time multi-tasking system model and a development environment for an elevator control system. Recently, as the elevator systems become large-scaled and operate with high speed, there are lots of software tasks to be processed with time constraints. Thus, the control systems are designed with distributed control structure and characteristics of typical real time systems. For structural design of such real time system, we introduce a multi-tasking model based on a real time operating system model and an software development environment based on virtual prototyping which simulates real system operation in the cross development environment. The developed system model and the development environment are successfully applied to development of a new elevator system with distributed control structure and its system reliability can be verified through numerous field tests.

Objective : This study is performed for the purpose of examining the efficacy of the scolopendrid(Scolopendra morsitans L) which has been to low back pain as a folk remedy. Methods & Results : Seventy patints with H.I.V.D. treated with the scolopendrid aquacupuncture and examined 4 tests; D.I.T.I., physical test, Oswestry disability index, and self-conscious pain rate were studied. And we follow up after discharge, we evaluated the present state and recovery period. Or we evaluated by herniated type and duration of onset. There was 58~97% of efficacy rate in each tests. Moreover, statistically valuable change in all 7D.I.T.I. points and in disability index and in self-conscious pain rate was showed. Conclusion : The scolopendrid aquacupuncture is possible to be effective terating the H.I.V.D patients. so we suggest the possibility using this new remedy to the H.I.V.D. patients.

The purpose of this research is make out construction specifications for International Construction. Using off-shore products incur cost increase and longer delivery term of construction. and inconvenient on International Construction. Expand the range of additional local products conforming to performance. Life Cycle Cost. maintainability. operability. user's acceptability, etc.. And this study is suggest the standard formats and the techniques for construction specification.

Tufted angiomas are rare slowly progressive vascular lesions found typically in children and young adults, usually involving the trunk and neck. Microscopically, groups of capillary tufts, many uncanalized, were found dispersed at various levels in the dermis. Some authors regarded tufted angioma as a member of lobular capillary hemangiomas. We describe a pyogenic granuloma mimicking acquired tufted angioma on the lip in a 59-year-old woman. We suggest that a term lobular capillary hemangioma$quot; may be preferable in this case.

Objectives : The purpose of this study was to investigate whether elderly and young adults differ in their recognition of facial expressions of emotion. Methods : A total of 120 (elderly group 53, young group 67) subjects participated in this study. Korean facial expressions of emotion including happiness, sadness, fear, anger, disgust, surprise and neutral were used as stimuli for facial affect recognition test. Computerized facial affect recognition test that consists of facial affect discrimination test and facial affect intensity test was performed. Results : For facial affect discrimination test, there was a significant difference between two groups (F==3.986, P<.01) after controlling the effect of education. Elderly participants showed significantly less correct recognition rate with sadness, anger and disgust (p<.05). For facial affect intensity test, there was no significant difference between the groups in recognition of emotional intensity. Chi-square test or t-test was done according to the clinical variables. Multivariate analysis of covahance was done to test group differences of correct recognition rate and emotional intensity. Conclusion : This is the first report of differential decrease of facial affect recognition in elderly using Korean facial expressions. This study suggests that the decrement of facial affect recognition maye be a part of normal aging process.

The aim of this study was to examine the effect of college athletes’ achievement goal and identity on performance strategy. The participants of this study were 300 of college athletes in Seoul and Kyoung-gi area. For the analysis of data, exploratory factor analysis, multivariate analysis of variance (MANOVA), two-way ANOVA, and hierarchical multiple regression were used. The results were as follows. First, the significantly important predictor variables of athletic identity were condition control, emotion control, self-talk, and imegery/goal setting predictor variable. Condition control, tense relaxation, and self-talk were significantly important predictor variables of achievement goal. Condition control, emotion control, and imegery/goal setting were significantly important predictor variables of athletic career, skillfulness, and performance avoid goal Two, athletic identity, and performance approach goal interacted and affected self-talk for the athletes among two-way, and three-way interaction variables.

Antibiotics are frequently administered for prophylaxis during anesthesia . Vaneomycin has increasingly become the antibiotic of choice due to the rising incidenee of resistant staphylococcal infections. Patients allergic to penicillin are candidates for vancomycin. Commonly reported adverse reactions of vancomycin include ; fever,chills, nausea, pain at the injection site, phlebitis, nephrotoxicity, ototoxicity, hypotension, cardiac arrest, broncho- spasm, noncardiogenic pulmonary edema and the so-called Red-Man's syndrome or Red Neck syndrome, Recently, we encountered two patients who had adverse reactions of vancomycin perioperatively. Vancomycin induced hypotension usually results from a negstive inotropic and vasodilator effect produced by a histamine-release phenomenon, which occurs most commonly with rapid intravenous infusion of the drug. Such a release of histarnine may also produce an acute urticarial flushing of the upper torso ($quot;Red Neek syndrome$quot;), pain and muscle spasm in the chest or parasternal muscles, which may mimic myocardial infarction. These effects usually abate promptly when the infusion of vancomycin is discontinued, and their resolution may be expedited by sdministration of an inotropic agent
