愼重燁,李瑞九,金顯五,朴啓仁 경희대학교 부설 식량자원개발연구소 1987 硏究論文集 Vol.8 No.-
Soy milk prepared from soy protein isolate and soy milk fermented with Lactobacillus acidophilus were adsorbed and desorbed by using Tenax-GC method and analyzed by Gas Chromatograph. It was found that this techingue was very efficient when the analytical results was expressed by the ratis of the peak area of each volatile to that of a fixed concentration of internal standard. Acetaldehyde, ethyl vinyl ketone, n-hexanal, n-hexanol, and 1 -octen-3-ol existed in soy milk. The content of acetaldehyde and diacetyl was increased while that of n-hexanal was reduced by lactic fermentation.

문제: 조직병리검사의 처방이 복잡하고 전문화됨에 따라 오류처방이 빈번하게 발생되고 이를 해결하기위한 프로세스가 복잡하여 부서간의 갈등과 업무의 가중, 또한 병원 수입 감소가 초래되었다. 목적: 발생된 오류처방의 유형과 발생율, 오류처방을 해결하기 위한 프로세스를 파악하여 이에 대한 문제점을 개선하여 업무의 효율성과 관련부서간의 부가업무 감소와 갈등해소, 더불어 병원수익을 향상시키는 것에 목표를 두고 활동하였다. 의료기관: 서울시에 소재한 종합병원 질 향상 활동: 조직병리검사 처방의 오류처방 발생 원인과 유형, 발생율을 조사하여 원인을 파악하고 개선을 위한 프로세스를 구축하여 질 향상을 도모하였다. 개선효과: 수술실에서 의뢰한 외과 입원환자의 일반조직병리검사 오류율은 개선 전 7.8%에서 개선 후 3.5%, 동결절편조직검사 오류율은 개선 전 28.6%에서 개선 후 0%로 이전보다 모두 개선되었다. 또한 수술실 간호사의 업무 만족도는 일반조직병리검사의 처방시 95%, 동결절편조직검사 처방시 90%로 높은 만족도를 보였다. 단 병리과의 경우 업무가 증가됨에 따라 초과근무시간이 증가하였다.
상악골과 비사골동에 이환된 백악질 골화성 섬유종(cemento-ssifying fibroma)의 치험례

The cemento-ossifying fibroma is a benign fibro-osseous tumor that may behave in an aggressive pattern. Although found predominantly in the mandible, most of these unusual tumors may arise in the maxilla and paranasal sinuses. Especially these lesion in the maxilla and sinuses behave more aggressively and are more prone to recur compared to mandibular counterparts. Therefore, more radical approach may be recommended than expectant observation or curettage in the initial management of this neoplasm. This is a case report of cemento-ossifying fibroma extended to maxillary sinus and naso-ethmoidal area treated by wide surgical excision after repeated conservative treatments.
복구과정을 고려하는 통신망 생존도 모형 및 트래픽 복구 알고리즘

In this study we present a telecommunication network survivability evaluation model considering restoration process. This is the extended model of the measure of disaster-effect which evaluates the social effect of telecommunication network disaster at the time of disaster occurrence not during the disaster period. With this new survivability model we can determine the restoration method to minimize the social effect of telecommunication network disaster during the disaster period. We establish an optimization model for restoration method during disaster and develop an heuristic solution algorithm for the detailed restoration method. That is, it can determine restoration paths in the network and assign the restoration traffic to the paths according to restoration process of failed network resources. The new survivability model and the traffic restoration algorithm are applied to the NSF network and the EON network for various disaster-restoration scenarios.
시상부위에 발생한 단일성 뇌농양 : 증례 보고 및 문헌고찰 Report of Two Cases and Review of the Literature

The authors present two cases of solitary thalamic abscess which were intially diagnosed as malignant thalamic glioma. After treatment with steroids and osmotic agents, the patients' clinical conditions improved after two to three days. However, sudden deterioration of consciousness level developed and the CT scan showed acute hydrocephalus with increment of thalamic low-density lesions. We performed extraventricular drainage and obtained CSF containing numerous inflammatory cells. This suggested the possibility that the lesion was a pyogenic abscess. which progressed to ventriculitis, rather than a malignant glioma. Stereotactic aspiration of the lesion confirmed thalamic abscess. These findings and review of previous reports of thalamic abscess suggested that early diagnosis and stereotactic drainage of the thalamic abscess is of primary importance.

A digital image display system is studied. A TV set is used for a display unit. The system is designed to display 256x212 pixels in a frame and 8 bit gray levels. A microcomputer system is utilized for the image processing which has a Z-80A cpu and s-100 bus. A image processing system which includes a refresh memory system is designed. Images taken by the input system are processed. The image sharpening techniques are introduced. The image edges are found and sharpend using Robert cross operator of spatial differentiation technique. The images are also processed to eliminate noise utilizing the neighbourhood averaging method.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.
