임현주,황종현,류재근,정병천,조용근,채성철,전재은,박의현 慶北大學校 醫科大學 1997 慶北醫大誌 Vol.38 No.1

목적 : 관상동맥질환의 위험인자로서 혈청지질 및 혈장 지단백에 대한 관심이 높아지고 있고 또 아포지단백이 관상동맥 질환을 일으키는데 다른 지질보다 더 중요하다는 연구가 많이 발표되고 있으나 우리나라에서는 아포지단백에 대한 연구가 그리 많지 않은 편이다. 이에 저자등은 혈중지질치와 새로운 위험인자로 알려지고 있는 아포지단백치를 측정하고 이들과 관상동맥질환 중증도와의 상관 관계를 알아보았다. 대상 및 방법 : 관상동맥질환이 의심되어 관상동맥조영술을 실시한 69명의 환자를 대상으로 하였으며 12시간 이상 공복후 혈청을 채취하여 총콜레스테롤, 중성지방, HDL-콜레스테롤, 아포지단백 AI (ape AI), 아포지단백 B (ape B)를 측정하였다. 관상동맥조영상 50%이상의 협착이 있는 혈관의 수 (lesion number), 최대협착을 합한 값 (lesion score), 각 분절의 최대협착을 합한 값 (total score), 가장 심한 협착 값 (peak stenosis) 등으로 관상동맥 중증도를 알아본 다음 이들과 혈청지질치, 아포지단백과의 상관 관계를 비교해 보았다. 상관 관계는 Spearman's correlation coefficient를 구하였다. 결과 : 관상동맥질환의 중증도와 각 지질치 간의 상관 관계를 비교해 보았을때 lesion number와 관계있는 것은 연령 (r=0.2789), 중성지방치 (r=0.2829)이며 lesion score와 관계있는 것은 연령(r=0.2911), 중성지방치0 (r=0.3316), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2361), apo B 치(r=0.2759), apo AI과 apo B의 비 (-0.3154)로 나타났다. Total score는 연령 (r=0.3100), 총콜레스테롤치 (r=0.2452), 중성지방치 (r=0.3022), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2770), apo B치 (r=0.2927), apo AI과 apo B의 비 (r=-0.3408)와 연관이 있었고 peak stenosis는 중성지방 치(r=0.3305), ape B 치 (r=0.2968), apo AI과 apo B의 비 (r=-0.3977)와 관계가 있었다. 연령으로 조정하여 partial correlation을 좌면, 관상동맥조영술상 중증도는 중성지방치 (r=0.3408), apo B 치(r=0.2877), apo AI과 apo B의 비 (r=-0.3460)와 유의한 상관 관계가 있었다. 이중 ape AI과 ape B의 비는 lesion score (r=-0.2640), total score (r=-0.3057), peak stenosis (r=-0.3460)와 유의한 상관관계를 보였다. 결론 : 이상의 결과로 보아 apo B치 그리고 apo AI과 apo B의 비가 관상동맥 중증도의 예견인자로 다른 혈중 지질 치보다 더 유용하다는 것을 알 수 있었다. Objectives : Recently, it was reported that the measurements of apolipoprotein levels may be valuable in the clinical assessment of coronary artery disease severity. However there are a few reports regarding to the relationship between coronary artery disease severity and apolipoprotein levels in Korea. Thus, we measured serum lipid and apolipoprotein levels and studied the relationship between coronary artery disease severity and serum lipids and apolipoproteins levels. Subjects and Methods : The 69 patients who underwent coronary angiography to evaluate chest pain were subjected to this study. We measured the levels of serum cholesterol, triglycerides, HDL cholesterol, apolipoprotein AI(apo AI) and apolipoprotein B(Apo B) and measured the severity of coronary artery disease by lesion number, lesion score, total score and peak stenosis. Then, we studied the relationship between coronary artery disease severity and apolipoproteins and calculated the correlation coefficient. Results : The results were as follows. There are significant correlation(r=0.3) between age, triglycerides, apo B levels, apo AI/B ratio and coronary artery disease severity. In controlling for age, tyiglycerides, apo B levels and apo AI/B ratio shows significant correlation(r=0.3) with coronary artery disease severity. Especially, apo AI/B ratio shows significant correlation(r=0.3) with lesion number, total score and peak stenosis. Conclusion : These results suggest that the apo B levels and the ratio of apo AI/B can be used as significant independent predictor for coronary artery disease severity rather than other serum lipid levels.

Granular cell tumors are relatively uncommon benign laryngeal lesions, especially in children. The granular cell tumor can occurs everywhere in our body. Half of all granular cell tumors occur in the head and neck, with a third of these occuring in the tongue. The larynx is relatively uncommon location, accounting for approximately 7% to 10% of all reported cases. Typically, the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia. But the tumor may be asymptomatic and be discovered only incidentally during a routine examination. Confirmative diagnosis should be made histopathologically and supported by immunohistochemical staining using S-100. Treatment of a granular cell tumor is complete excision with an attempt to maintain normal structures. We experienced a 14-year-old woman with laryngeal granular cell tumor, which involves the epiglottic lower margin. She was successfully treated with complete excision under laryngomicroscopic dissection. So we report it with a review of literatures.

The relative density seems to be important as a factor of controlling the physical properties in the case of cohesionless soil ground as sand. Therefore, the study is more important about the method for reappearing he same relative density when the specimen of shearing test is to be produce or the model test of ground is to made. In this study, the apparatus making use of the multiple sieving pluviation method-one of the reappearance of relative density-could be made. Using this apparatus, tests were practiced varying the factors such as the size of sieve mesh and the number of sieve, the amount of falling discharge, the falling height etc. about the standard sand in Jumunjin and Hadong sand. When laboratory test is perfomed by the cohesionless soil, it presents the method for reappearing of the relative density in field.

In this study, the relation of discharge patterns with the radiated electromagnetic waves is investigated by measuring electromagnetic waves using a antenna and a spectrum analyzer. The patterns of radiated electromagnetic waves measured at the atmospheric pressure in Liquid Nitrogen(LN_(2)) during the partial discharges in nonuniform electric field depend on positive DC power. From these points of view, it is considered that these results obtained from this investigation may be used as fundamental data for diagnosis and prediction of insulation on the equipments of superconducting and cryogenic applications.

신경회로망에서 뉴런간의 연결도를 이용한 4백 배치 문제 해결 알고리즘

In this paper we have proposed a method for solving a four-coloring problem using adjusted information transmission between adjacent neurons in neural networks. These algorithms are based on McCclloch-Pitts binary neuron model neural networks. If a map shares n regions, a 4×n neural array is used to color a map of n regions where each neuron as a processing element performs it. By programming these algorithm by a C-language in IBM PC 486 DX and adapting it to various examples, we have showed the ability of our system. If one neuron is selected among four neurons, the strength of order three neurons is wakened. So, by transmitting the information of selected neuron, adjacent neurons cannot share the same color.

주재익,정현주 전남대학교 치과대학 1995 전남치대논문집 Vol.7 No.1

The purpose of this study was to evaluate the bacterial adherence on e-PTFE membrane immersed in whole saliva from subjects with different periodontal status. Experiment involved 3 subjects groups : 5 persons with healthy periodontium(probing depth below 3mm and no signs of gingival inflammation including bleeding on probing), 10 patients with gingivitis(probing depth below 3mm and apparent signs of gingival inflammation), and 10 patients with advanced periodontitis(probing depth over 7mm and apparent signs of gingival inflammation). Each disease group was included before and after scaling and root planing treatment. After obtaining whole saliva from each subject, e-PTFE membrane(Gore-Tex periodontal membrane : GTPM??, W.L. Gore & Associates, Flagstaff, USA) specimens were immersed at room temperature in the saliva aliqouts for 1, 3, 7 days. The weight between pre-and post-immersion in saliva was measured with the analytical balance and the difference was recorded. The specimens were processed for SEM observation. The bacterial adherence on the membrane specimens was evaluated using the scanning electron microscope images. The obtained results were as follows : 1. There was no difference in the weight of bacteria adherent to e-PTFE membrane specimens according to the periodontal status and the immersion periods. 2. As the exposure time to saliva increased, the bacterial adherence to the membrane specimen significantly increased in all groups(P<0.005). 3. As the severity of periodontal disease increased, the bacterial adherence to the membrane specimens significantly increased(P<0.001). 4. After scaling and root planing, the bacterial adherence to the membrane specimens significantly decreased in gingivitis and periodontitis patient group(P<0.001). These results suggest that bacterial contamination on exposed barrier membrane surface be reduced through improvement of periodontal status and oral health environment before and after GTR procedure for the successful outcome.

This paper is the eye region which is used with confirmation element of face image it uses the SIFT and it extracting method proposes. The eye region image where becomes model and it composes the keypoint descriptor which is a SIFT result of the input image which it will extract. It uses the keypoint descriptor which and creates it composes a each feature vector, and the judgement where affine transform should have existed on after two feature points which adjusts with each other, against the feature point field which confront above half as the case eye region where the with each other same affine transform will exist it judged. There is not a test result learning process, more quickly recognition method of existing methods than the possibility of getting the result which extracts the region it was.
