쑥 양침액의 투여와 관련된 변화를 관찰한 결과, 전 시험기간을 통해 단회투여 후 14일 동안 일반증상, 치사율, 체중변화, 부검소견, 장기중량변화, 혈청생화학적 분석등의 각종 지표에 의한 안전성을 평가했을 때 1× 실험군에서는 대조군에 비해 유의한 변화를 관찰할 수 없었으며 10×쑥약침액 투여 후 관찰된 체중의 감소, 혈정생화학적 수치의 유의한 변화는 과용량의 시험물질에 의한 영향으로 생각된다. 한편, 5×, 10×의 쑥약침액을 투여한 실험군에서 활동력 저하, 호흡수 감소, 졸음 및 무기력등의 임상증상이 관찰되었는데 이는 중추신경계 억압에 의한 증상으로 보고??되어 있다. 또한, 혈액내 혈청을 분리하여 간세포 이상의 지표로 사용하고 있는 GOT, GPT를 측정하였고 혈청 중의 total enzyme을 측정하여 LDH의 활성치를 계산, 이것을 심폐질환, 혈액질환, 간질환의 유무를 알아내는 지표로 사용하였으며 간염, 간경변, 골질환의 유무를 알아내는 지표로 사용하는 ALP-s를 측정하였다. 농도에 따른 쑥 약침액의 영향을 알아본 결과 쑥 약침액을 대조군에 비하여 단회투여시 1×의 농도에서는 대조군에 비해 유의한 차이를 나타내지 않았으나 5×, 10×의 농도의 실험군에서는 상당히 유의한 차이를 나타냄으로써 쑥 약침액의 과용량의 투여는 마우스의 간세포, 골세포, 심폐기관 등에 유해작용을 일으킬수 있음을 알 수 있었다. 본 실험을 통해 1×의 쑥 약침액의 용량은 급성 독성시험 결과 무해한 용량으로 판단되며, 5×이하의 용량군을 세밀히 나누어 검토할 필요가 있다고 판단된다. Acute toxicity of Artemisia Nakai Aqua-acupuncture Solution(ANAS) as studied in ICR mice. Mice were injected inrtapeitoneally with single dose of 1×, 5×, 10× ANAS and toxicological responeses were observed for consecutive 14 days. Mortality, clinical signs, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with 1× and 5× ANAS were not affected during the experimental periods. With the 10? ANAS treatment, dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. There results suggest that 1× ANAS causes no toxicity that 10× ANAS causes toxicity in acute toxicity test.

홍종우(Jong Woo Hong),이선경(Seon Kyung Lee),반태학(Tae Hak Ban),지성길(Sung Gil Ji) 대한산부인과학회 2002 Obstetrics & Gynecology Science Vol.45 No.3

N/A Objective: Telomerase is a ribonucleoprotein enzyme which stabilizes chromosomal structure, thereby inducing cellular immortality. We investigated telomerase activity and human telomerase reverse transcriptase (hTERT) mRNA expression in relation to high-risk human papillomavirus (HPV) DNA presence in cervical carcinomas. Met hods: From December 1995 to December 1999, at the department of obstetrics and Gynecology of Kyung-Hee University Hospital,32 cervical carcinomas and 5 corresponding nontumor cervical tissues were obtained and the samples were immediately frozen and stored at -70℃. Telomerase activity was measured by using telomerase PCR ELISA, a modified version of the TRAP. Analysis of the expression of hTERT mRNA was performed by quantitative RT-PCR and the analysis of the HPV E6 gene was performed by DNA-PCR. Result: All of the carcinomas examined exhibited strongly positive for telomerase activity (OD>0.24), whereas telomerase activity was week or not found in the 5 corresponding nontumor cervical tissues. Quantitative RT-PCR analysis demonstrated significantly increased hTERT mRNA expression levels (>0.024) in most carcinomas comparing to control groups. There was no obvious relationship between telomerase activity levels and the clinical parameters examined including age, clinical stage, pathology, differentiation, tumour size, LN involvement and invasion depth except lymphovascular space invasion (p=0.03). In the correlation between the levels of hTERT mRNA expression and telomerase activity, correlation index which was 0.916,shows high correlation (p=0.01). According to the analysis of HPV E6 gene,29 of 32 (90.6%)carcinomas showed HPV E6 positivity. Conclusion: There is a strong association between telomerase activity and hTERT mRNA expression, and up-regulation of hTERT probably plays a role in the progression of cervical carcinomas. Telomerase is at least partially activated by viral oncogenes of high-risk types. There is no obvious relationship between telomerase activity levels and the clinical parameters except LSVI (p=0.03). These findings provides that telomerase may play an important role in the early stage of carcinogenesis.

This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

포스트사회주의적 변화에서의 민간(民間)의 역동성과 선행성(先行性)

김재석 서울대학교 통일평화연구원 2019 통일과 평화 Vol.11 No.2

This paper investigates the leading role of minjian in postsocialist transformations of China and North Korea and illuminates the historical and sociocultural conditions that have contributed to its initial formation and survival under the socialist government. By understanding key characteristics of minjian, we can understand the dynamic relationship between state apparatuses and minjian. According to the general explanation, China’s postsocialist changes began in the mid-1980s with the central party-state’s leadership symbolized by Deng Xiaoping. Similarly, North Korea’s postsocialist transformation is also believed to advance under the supreme leader Kim Jong-un’s leadership. I critically evaluate the effectiveness of the analytical framework that focuses on the central government’s political decision and leadership in explaining postsocialist transformations. Specifically, this study analyzes grassroots changes in minjian such as unofficial domestic and overseas trades and ordinary people’s growing participation in various non-socialist activities, which appeared before the official initiation of postsocialist policies. Following this research’s model of “minjian prior to the government,” not the party-state but minjian first formed non-socialist practices. Only after the practices had generated certain positive outcomes, the party-state recognized the minjian practices and started the official version of postsocialist reform. 본 논문은 중국과 북한의 포스트사회주의적 변화에서 민간이 담당하는 선행(先行)적 역할과 이 역할이 형성되고 지속되어 온 역사적·사회문화적 배경을 조명하고, 민간과 국가기구 사이의 역동적 관계를 이해하는 것을 목적으로 한다. 중국 정부와 당은 역사적으로 형성된 백성(民)과 관리(官)의 이분법적 구분을 답습하여, 민간을 사회주의 체제 외부(体制外)에 있는 모든 것과 연관시켰다. 연구자는 민간개념을 시민 혹은 시민사회에 대한서구 정치이론의 규범적 전제들로부터 상대적으로 자유로운 개념으로 간주한다. 기존의이론적 전제들로부터 자유로운 민간개념은 포스트사회주의적인 변화에서 개인 혹은 집단들이 행하는 실제 역할과 이들이 국가기구와 맺는 관계를 구체적으로 분석하는 데 유용하다. 일반적으로 중국의 포스트사회주의적 변화는 1980년대 중반 덩샤오핑으로 대표되는중앙정부의 지도력에 의해 추동되었다고 이해되며, 북한의 변화 역시 최고지도자인 김정은이 이끄는 강력한 중앙권력에 의해 지도되고 있는 것으로 나타난다. 중앙권력의 정치적 결단에 중점을 두어 포스트사회주의적 변화를 설명하는 접근법의 유효성을 비판적으로 검토하기 위해, 본 연구에서는 중국과 북한에서 공식적인 포스트사회주의적 변화가 나타나기 이전 시기에 민간의 영역에서 이와 유사한 변화의 움직임이 나타났는지를 분석한다. 연구자가 가정한 ‘선(先) 민간, 후(後) 정부’ 모형에 따르면, 중국과 북한의 변화는정부가 아닌 민간이 비공식 차원에서 비(非)사회주의적 관행을 만들어 내고, 이것이 일정한 성과를 거두자 정부가 해당 관행을 추인하는 방식으로 나타난 것으로 이해할 수 있다.
