This study was investigated to prove the effect of GMGHT on the gultamate receptor, free radical and brain damage in rats sujected to Brain Ischemia The results were as follows; 1, GMGHT showed significant inhibitory effect of GMGHT on LDH release induced by NMDA, AMPA, and kinate. 2. GMGHT showed significant inhibitory effect of GMGHT on LDH release induced by BSO and Fe/sup 2+/. 3. GMGHT decreased coma duration time in a infatal dose of KCN and showed 30% of survival rate in a fatal dose. 4. GMGHT decreased ischemic area and edema incited by the MCA blood flow block. 5. GMGHT showed improvement of forelimb and hindlimb test after MCA occulusion in neurological exemination. 6. GMGHT showed no significant change after MCA occulusion in pathological observation as normal group. These results indicate that GMGHT can be used in the brain damage sujected to Brain Ischemia. Further study will be needed about the functional mechanism and etc.

Confusion of a patent ductus arteriosus (PDA) for the descending thoracic aorta is a fatal error occurring occasionally in infants or neonates. As a result, the left pulmonary artery (LPA) may be misconceived as the PDA, and ligated. This surgical mishap of other hospital leads to serious congestive heart failure and loss of left lung function due to the underdevelopment in the peripheral vascular and alveolar structures in neonates and premature infants. In this report, 3 cases of LPA ligation and subsequent treatment are presented.

THe Purpose of this paper is to match the feature point of man-made structure and to obtain the DEM which are occluded in a image plane. We use the trinocular matching with epipolar lines and planes. If an occlusion appears at one of the trinocular images, the DEM mapping is used to estimate the height of feature points in it.

Objective : The purpose of this study is to report the oriental-western cooperative treatment on opthalmic and dermatologic disease caused by adverse effect of filler injection galbella region. Method : After filler injection, a patient suffers from spontenous blineness and palsy of oculomotor and trochlear nerve on right eye and erythema on glabella and nasal region. She is admitted to kyung-hee oriental hospital for 2 weeks with oriental(herbal-medicine, acupunture and nega treatment) and western(department of opthalmology, dermatology and plastic surgery measurement) treatment. Result & Conclusion : Nerve palsy was recovered near to normal. And skin legion was proceeded to recovery period without any complication. This recovery speed with oriental-western cooperative treatment is much faster than usual treatment.

Objectives : This research was performed to investigate effect of Samul-tang-gamibang against focal cerebral ischemic damage after middle cerebral artery occlusion(MCAO). Methods : This research was used rats which were against focal cerebral ischemic damage by MCAO. It was used Zea Longa's theory and Belayev's methods to give rise to focal cerebral ischemic damage by MCAO. After 7days later, we drew out the brain and then had frozen and dyeing it and we had taken a picture to measure of the damaged area in each brain section. We determined the Neurological Index and tested the Foot-fault test and Roatated test to appraise the fall of motion ability result from cerebral ischemic damage. Results : The results of the experiment are as follows. 1. Samul-tang-gamibang reduced infarct size of sample group compared to control group at 7 day after MCAO. 2. Samul-tang-gamibang reduced infarct volume of sample group compared to control group at 7 day after MCAO. 3. Samul-tang-gamibang reduced foot-fault index of sample group compared to control group at 5,7 day after MCAO. Conclusions : Samul-tang-gamibang has protective effects against ischemic brain damage and had significant reduced infarct size and infarct volume of Rt-MCAO.

We have experienced two cases of coronary revascularization without extracorporeal circulation in a 63 year old female patient and a 75 year old male patient. The first patient had the lesion which was the nearly total occulusion of mid-LAD, about 90% luminal narrowing of second diagonal branch and less than 50% stenosis of proximal RCA. The other male patient had a single vessel disease involving about 95% stenosis of proximal LAD and 1st diagonal branch. PTCA failed in the irst patient because of relatively long sinus pause during procedure In both of the patients, the coronary revascularizations were done at distal LAD and diagonal branch using left internal mammary artery and saphenous vein graft under the beating state, respectively. The postoperative courses were uneventful and the patients were discharged without any complications.

Background: Minimally invasive techniques for open heart surgery are widely accepted in these days. There are minimally invasive approaches by the right or left parasternal incision and another approaches by mini-sternotomy of upper or lower half or sternum. We report the safety and efficacy of minimally invasive technique with right parasternal incision compared with the routine full sternotomy. Material and Method: From April 1997 through February 1999, 20 patients(Group A) underwent minimally invasive cardiac operations. We chose 41 patients(Group B) whose preoperative diagnosis were the same and general conditions were similar and who underwent routine full sternotomy before April 1997. We compared A group and B group in many aspects. We performed routine full median sternotomy in B group but we did a minimally invasive technique through a small right parasternal incision in A group. Result: mean age was 36.1 years in both groups. In disease entities, there were 11 cases of ASD, 9 cases of mitral valve disease in group A, and 16 cases of ASD, 25 cases of mitral valve diseases in group B. In ASD, operation time, cardiopulmonary bypass time of aortic occulusion time were 263 min, 82 min, and 41 min in group A and 180 min, 53 min, and 32 min in group B. In mitral valve disease, operation time, cardiopulmonary bypass time and aortic occlusion time were 267min, 106 min, and 70min in A group and were 207 min, 82 min, and 69 min in group B. There were significant differences in operation time, CPB time, and ACC time between group A and group B. There was a significant difference in the amount of bleeding in postoperative day 1 between group A and group B of mitral diasease. However, there was no significant difference in the amount of bleeding in other comparisons. Mean length of incision was 8.7 cm in group A. There was no significant difference in postoperative complications between A group and B group. There was no mortality in either group. Conclusion: We conclude that this minimally invasive technique with right parasternal incision is cosmetically excellent but it is not effective in reducing operative time and there was no significant difference in recovery time and postoperative complications compared with routine full sternotomy.

Purpose: The purpose of this study is to develop a deep learning-based personal protective equipment detection model for disaster prevention at construction sites, and to apply it to actual construction sites and to analyze the results. Method: In the method of conducting this study, the dataset on the real environment was constructed and the developed personal protective equipment(PPE) detection model was applied. The PPE detection model mainly consists of worker detection and PPE classification model.The worker detection model uses a deep learning-based algorithm to build a dataset obtained from the actual field to learn and detect workers, and the PPE classification model applies the PPE detection algorithm learned from the worker detection area extracted from the work detection model. For verification of the proposed model, experimental results were derived from data obtained from three construction sites. Results: The application of the PPE recognition model to construction site brings up the problems related to mis-recognition and non-recognition. Conclusions: The analysis outcomes were produced to apply the object recognition technology to a construction site, and the need for follow-up research was suggested through representative cases of worker recognition and non-recognition, and mis-recognition of personal protective equipment.
