나노/마이크로 압입 시험에 의한 플라즈마 세라믹 용사코팅의 특성 평가

최세영(Se-Young Choi),채영훈(Young-Hun Chae),김석삼(Seock-Sam Kim) 한국트라이볼로지학회 2003 한국트라이볼로지학회 학술대회 Vol.36 No.-

The most controversial topics in plasma sprayed ceramic coating systems are recently mechanical properties such as bond strength, cohesive strength, toughness and so on. In this research, critical fracture load(Pc) and interface toughness(Ks) of four coatings materials were computed from the applied load, crack length and Young's modulus data which were measured by micro-vickers and nano indentation test. It is reasonable to consider the Pc value as comparison data of bond strength, and the Kc value, considering a trace of indent in the interface, was computed by a modified (E/H)I<SUP>½</SUP> ratio. In the case of the high loads (9.8N and 19.6N) in the Al₂O₃+13%TiO₂ coating, the critical point(Pco) at which the coating was broken was found. Also, used by a XRD phase analysis, we checked a change of coating' s properties, predicting a possible change of the phases in plasma sprayed coating.

중추에서 Prostaglandin계가 Renin-angiotensin System에 미치는 영향

Role of prostaglandins on the renin-angiotensin system in the central nervous system was examined in normotensive and 2-kidney, 1 clip (2K1C) hypertensive rats. The experiment was done under thiopental (50 ㎎/㎏, IP) anesthesia. Captopril and indomethacin were injected into the right lateral cerebral ventricle. Arterial blood pressure and heart rate were recorded from the femoral artery. Intracerebroventricular (ICV) captopril (1 ㎎) caused a decrease in mean arterial pressure in both normotensive and 2K1C hypertensive rats. The depressor response to captopril was more sensitive in hyper-tensive rats than in normotensive rats. Indomethacin treatment (ICV, 200 ㎎) altered the depressor response to captopril neither in normotensive nor in hypertensive rats. These results suggest that the cardiovascular effect of renin-angiotensin system in the central nervous system may not be mediated via prostaglandin systems in normotensive and 2KlC hypertensive rats.

최영환,도남용,나한조,이도용,노용훈,김완수,최종선 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.2

Background and Objectives : When p53 cancer suppressor gene, occurs gene deletion or point mutation, malignancy develops by loss of p53 function with abnormal p53 protein. The Epstein-Barr virus (EBV) is the causative agent of certain type of lymphoma and undifferentiated nasopharyngeal carcinoma. However, the role of EBV as a causative factor in other head &eck tumors is not fully elucidated except nasopharyngeal carcinoma. This study, the author examined that p53 expression and detection rate of EBV correlate to development of laryngeal and hypopharyngeal squamous cell carcinoma(SCC) and play the possible role of prognostic indicators. Materials and Methods : Formalin-fixed, paraffin-embedded tissue specimen from 32 cases of larynx and hypopharyngeal squamous cell carcinomas were studied by immunohistochemical staining for p53 and EBV. The results of analysis were compared with clinicopathological parameters. Results : p53 expression was 56.3% (18 cases) and the detection rate of EBV was 43.6% (14 cases) of 32 cases in laryngeal and hypopharyngeal squamous cell carcinomas. p53 expression was correlate with histologic grade (p<05) only. Detection of EBV was not correlate with clinicopathological parmeters. Conclusion : These results suggest p53 expression and the detection of EBV may be related with development of laryngeal and hypopharyngeal squamous cell carcinoma. And, the expression of p53 protein can be used as a prognosticator in laryngeal and hypopharyngeal squamous cell carcinoma under certain limitation.

Thirty children with respiratory tract infections, 17 with acute and chronic bronchitis, 5 with sinusitis, 4 with rhinitis, 3 with asthma, 1 with tonsillitis, were given Broncho-vaxom^?? one capsule per day on an empty stomach for 1 month to evaluate the efficancy of the drug on acute and chronic respnatory tract infections in children. After the medication, we observed the changes of clinical symptoms, and side effects. The results are as follows; 1. The symptomatic improvements after Broncho-vaxom^?? administration were as follows; expectoration(80%), fever(72%), rhinorrhea(67%), hoarseness(67%), and coughing(65%). 2. Combined treatment with antibiotics was necessary in 19 cases(63%). 3. The degree of response were observed as mild improvement in 3 cases(10%), moderate improvement in 13 cases(84%), and excellent improvement in 1 cases(47%). 4. The side effect of Boncho-vaxom was not observed during this study.

O-링 테스터의 측정팁 구조개선

최기훈,여인철,김영탁 중앙대학교 미래신기술연구소 2001 미래신기술연구소 논문집 Vol.10 No.2

It is usual that the medical examination of human body need special knowledge and equipments. Thus we have to spend time and energy on going to special place such as hospital where doctors and equipment are. Which often cause missing a good chance of medical treatment as well as giving us inconvenience. However may simple and convenient equipments were developed for checking our health conditions recently. O-ring test is accepted as one of useful methods to examine our health conditions. Also the test is recognized as a useful means to judge if some medical substances or foods are beneficial or harmful to our health without any special equipment and medical knowledge. An automatic O-ring test machine has been developed[11]. However the tester have a problem that the pattern of applied force to the O-ring is different from that of manual case. In this study, the reaction force tip is modified and the validity of the tip is verified through experiments.

가우시안 빔 프로파일의 CPT를 위한 비선형 주사속도변조

최덕규,한찬호,정영헌 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(B)

A scan velocity modulation(SVM) technique has been widely used for compensating the deterioration of picture quality due to the beam profile effect of the color picture tube(CPT). In conventional SVM system the so-called linear SVM method has been employed, whose modulation velocity is linearly proportional to the variation in the video signal amplitude. However, the effect of picture quality improvement is irregular with video signal amplitude in the linear SVM. In this paper we report a theoretical analysis of the SVM effect on the spatial brightness distribution of CPT according to the variations in luminance signal amplitude and differentiation circuit characteristic. We also propose a nonlinear SVM method based on the results of the theoretical analysis for optimum picture quality improvements. In computer simulation we confirmed uniform improvements in picture quality by the SVM of nonlinear amplitude transfer characteristic.
