Zn를 첨가한 고온초전도체 Y Pr Ba₂Cu₃O 의 Raman 분석

강재필,김성재,박현진,노태호,송승기,박영민,전인 明知大學校 自然科學硏究所 1997 자연과학논문집 Vol.15 No.-

고온초전도제 Y Pr Ba₂Cu₃O 에 Zn를 첨가(x=0.00, 0.05, 0.10, 0.15, 0.20)하여 전이온도 측정, X-ray회절 실험과 Raman 실험을 하였다. Raman 측정결과 다섯 개의 시료가 일반적인 YBCO 초천도체의 Raman 스펙트럼에서 존재하는 다섯 개의 대칭활성모드(115cm¹,150cm¹.340cm¹,440cm¹,504cm¹)가 관측되었다. 이것은 Cu 와 관련된 대칭활성모드의 주파수가 모두 저주파 변위를 나타내어 Zn가 Cu(1)과 Cu(2)에 치환되었음을 의미한다. 저주파 변위 정도는 Zn에 거의 무관했으나, Raman 스펙트럼의 각 피이크의 선폭은 치환된 Zn에 의해 증가했다. 이 결과는 Zn가 Cu자리에 어느 한계 이상은 치환되지 못하고 시료 내에서 불순물상을 형성함을 나타내는 것이다. We measured transition temperature, X-ray diffraction pattern and Raman spectra of Zn added(x=0.00, 0.05, 0.10, 0.15, 0.20) high-T superconductor Y Pr Ba₂Cu₃O All samples have been observed five symmetric activity modes(115cm,150cm¹.340cm¹,440cm¹,504cm¹)which exist in Raman spectrum of general YBCO superconductor. This means Zn is substituted for Cu(1) and Cu(2) due to the fact that symmetric activity mode frequency related with Cu shows low-frequency shift. The degree of low-frequency shift was nearly independent on Zn but line width of Raman spectra peaks were increased by the substituted Zn. This results shows that Zn does not be substituted for Cu-site more than limit value and formes impurity phase in the sample.

Fatigue cracks due to thermal stratification or corrosion in pipelines of nuclear power plants can cause serious problems on reactor cooling system. Therefore, these cracks must be detected before the crack growth to ensure the reliable operation. Ultrasonic techniques have been employed for detecting and sizing these fatigue cracks propagated from the back wall of pipelines. But, it is very difficult to sizing fatigue cracks because of low amplitude of the diffracted tip signal, high noise signal and ultrasound transmission through the closed crack surface. In this study, the signal reflected from the back wall is adopted instead of weak tip signals. In addition, the rate of decrease in amplitude of reflected signals due to reflection at the crack surface and diffraction at the crack tip is used to size fatigue cracks.

Background: To the emergency physician, issuing a death certificate is becoming a burden as the DOAs(Deaths on Arrival) have increased in recent years. We analyzed the agreement on the causes of death issued by emergency physicians and attempted to find out whether emergency physicians complied with the guidelines for issuing death certificates. Material & Method: A survey questionnaire containing twelve pre-selected DOA cases which were supplemented with relevant past medical history and physical examination was used. The cases, with varying causes of death, were chosen from the medical records of DOA patients who presented to the emergency department at Severance Hospital, Yonsei University College of Medicine, from January 1997 to December 2000. The questionnaires were sent to 60 emergency physicians(22 specialists and 38 residents) at 22 university-affiliated teaching hospitals and 2 general hospitals across the nation. They were asked to identify the most probable direct cause of death for each of the 12 cases. The same questionnaire was sent to medical examiners at the National Institute of Scientific Investigation and to a Korean emergency physician at Albert Einstein College of Medicine in New York, USA. We also included an open question about the optimal age for the use of 'senility' as a cause of death. Results: All 60 emergency physicians responded to the survey. The average number of causes of death per case was 9.7(7∼ 14). The range of concordance of causes of death was 23.3% to 66.6%. Out of a total of 720 causes of death given by the emergency physicians,35(4.9%) failed to adhere to the death certification guidelines, Also, 210 causes of death were not listed in the Korean classification of standard causes of death. Interestingly, the medical examiner answered 'unknown etiology' and the emergency physician in the USA answered 'cardiopulmonary arrest' or 'respiratory arrest' in most cases. Regarding 'senility' as a cause of death, 22 physicians(36.7%) thought the optimal age was over 80 years. Conclusion: A significant lack of agreement exists in determining the cause of death for the DOA patients arriving at emergency departments, Therefore, an all-out effort is essential to find ways to improve and resolve this situation. As the death certificate is a legal document and a basis for vital statistics, emergency physician should seek a rational consensus to improve and resolve these inconsistencies.

위선암에서 p53과 EGFR 및 PCNA 발현에 관한 연구

강현욱,양승하,강상균 순천향의학연구소 1997 Journal of Soonchunhyang Medical Science Vol.3 No.1

Expression of oncogene in the gastric adenocarcinoma was considered as a determinant factor of cancer progression or prognosis by some authors, however, the results were so fluctuated according to the authors that there was no uniform agreement in their clinicopathological correlation as well as in its practical application. To evaluate correlation between the pathologic finding and the expression of p53, EGFR and PCNA, immunohistochemical studies were performed on paraffin-embedded sections of 84 gastric adenocarcinomas. Pathologic findings were classified as 4 subgroups by their histologic types, differentiation, invasion and lymph node metastasis. The correlation of PCNA labelling index with various clinicopathologic factors and oncogene expression was studied. The results were as follows; 1. p53 expression was seen in 47cases(55.56%) of gastric carcinoma, and correlation between p53 expression with tumor type, differentiation, invasion and lymph node metastasis was not proved. EGFR positive expression was found in 37(44.05%) cases and was increased in advanced gastric carcinoma, and cases of lymph node metastasis. 2. Co-expression of p53 and EGFR was observed in 18 cases(33.33%), suggesting existence of both oncogene in the same case, while both negative cases were 18 cases(33.33%) that suggest the possibility of presence of the other factors. 3. PCNA labelling index was higher in advanced gastric carcinoma and in cases of lymph node metastasis, but there was no statistical significance. 4. There was no statistical significance between PCNALI and p53 expression. 5. PCNALI and EGFR expression was parallel with pathologic finding such as differentiation, progression and metastasis of the carcinoma, these results suggest that there was significant correlation between PCNALI and EGFR. 6. PCNALI was statistically significant between two groups of both p53 and EGFR positive and both negative. 7. PCNALI showed statistical significance between EGFR positive and negative groups in cases of lymph node metastasis. In summary, the value of p53 expression as a prognostic factor was still doubtful but EGFR and PCNA expression tended to be associated with tumor progression and seemed to be objective and reliable prognostic factors, respectively. Combined method of EGFR and PCNA thought to be more helpful in preoperative decision or prediction of prognosis in gastric carcinoma.

People are getting more interested in their “quality of life” as they achieved certain level of economic development. Governments pay great attention on well-being and happiness of people as well and try to find the best way to improve citizens' quality of life. However, South Korea is still on 27th out of 39 OECD and G20 countries in quality of life index, which means that there are great needs to improve Koreans' quality of life. Moreover, it is expected that Korean women's quality of life might be worse than this in its patriarchal environments. In fact, there are few research regarding Korean women's quality of life and it is unknown what personal and social factors affect Korean women's quality of life and how we can improve it. This research attempts to find out factors related to Korean women's quality of life through the surveys of 536 Korean women. The results show that quality of life is most influenced by factors such as self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. In addition, happiness of Korean womem is greatly affected by various factors such as mental health, interpersonal relationship, self-respect, self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. Among various factors related to quality of life and happiness of Korean women, scores of self-respect, self-fulfillment, and interpersonal relationship are high, while scores regarding income are relatively low. Key words:Quality of Life, Happiness, Maslow
