연구배경: HSVtk/GCV를 이용한 유전자치료에서 면역반응은 1) adenovirus 혹은 retrovirus와 같이 벡타로 사용된 virus의 단백질, 2) 치료목적으로 이입된 HSVtk 유전자의 생성물, 3) 암세포에 대해서 일어날 수 있다. 그리고 이러한 면역반응은 cytokines의 생성 혹은 cytotoxic tumor-specific T-cell의 생성을 초래하여 bystander effect에 의한 살상효과를 증가시키거나, anti-tumor immunity를 유도하여 tumor vaccine의 효과를 나타낼 수 있다. 한편 이와는 대조적으로 면역반응용 HSVtk 유전자를 발현하는 세포들을 파괴하여 이입된 HSVtk 유전자의 발현기간을 제한함으로서 유전자치료의 효과를 감소시킬 수도 있다. 본 연구는 retrovirus 벡타로 이입한 HSVtk 유전자치료에서 면역체계가 bystander effect에 의한 살상효과에 미치는 영향을 규명하고 면역체계가 이입한 유전자의 발현에 미치는 영향을 조사하고자 하였다. 방 법: Immunocompetent mice인 Balb/c mouse와 immunodeficient mouse인 Balb/c-nude 및 SCID mouse에서 retrovirus 벡타를 사용하여 HSVtk 유전자를 이입하고 치료효과를 조사하였다. 그리고 Balb/c mouse에 면역억제제인 cyclosporin을 투여하여 면역억제제가 bystander effect 및 유전자치료 효과와 유전자의 발현기간에 미치는 영향을 조사하였다. 결 과: Balb/c mouse에 HSVtk 유전자를 이입하고 GCV를 투여한 군은 GCV를 투여하지 않은 대조군에 비해 종양의 성장이 유의하게 억제되었으나 Balb/c-nude mouse와 SCID mouse의 경우 GCV를 투여한 군과 대조군 사이에 유의한 차이가 없었다. 면역억제제인 cyclosporin을 투여한 군에서 유전자 치료 효과가 cyclosporin을 투여하지 않은 정상 mouse에 비해 치료효과가 유의하게 작았다. Cyclosporin 투여에 따른 유전자의 발현기간에는 유의한 차이가 없었다. 결 론: Retrovirus 벡타를 사용한 HSVtk 유전자치료에는 면역증강이 치료효과를 증가시킬 것으로 생각된다.

The purpose of the present study was to investigate how 4-to 5-year-olds approach a competitive/cooperative task to obtain a resource. Sex and age differences were examined for the behavior and resource utilization of this task. The subjects were 74 same-age, mixed sex groups of 4 children each in three kindergartens in a large city. Each group of 4 children were classmates. The children were videotaped in a play situation where one child could view a cartoon movie (i. e. acquiring a resource) with the assistance of two children (one to turn the film tape and one to push the light-button), and the fourth child was a bystander. Time at each position and physical and verbal behavior constitute the data which were analyzed by ANOVA and ${\chi}^2$. The results of the time analysis showed that children cooperated quickly and were able to view the cartoon(resource utilization) for a large part of the session. High resource utilizers compared with low resource utilizers, exhibited more self-assertive and helping behaviors. Boys achieved more viewing time while girls were bystanders for a greater amount of time. Boys showed more physical and verbal behaviors during the task. Four-year-olds achieved less viewing time than 5-year-olds, indicating 4-year-olds were less effective in eliciting the help of their peers.

Purpose: The performance rate to perform Cardiopulmonary Resuscitation (CPR) by witness in out-of-hospital Cardiac Arrest (OHCA) is very low in South Korea. To prevent the death caused by OHCA, it is important to encourage the witness to perform CPR actively. The purpose of the study is to investigate the influencing factors to affect bystander CPR rate. Methods: I conducted a questionnaire survey from 25 February to 4 March, 2013, receiving responses from 517 people in Korea. The questionnaire included social demographic factors, history of heart disease, knowledge of CPR, and the reliability of emergency medical service (EMS). A logistic regression analysis was conducted. Results: Among the 517 respondents, 294 (57.4%) had intention of performing CPR. Multiple logistic regression analysis found the following significant predictors of CPR intention: gender (odds ratio [OR] = 0.390), age (OR = 1.024), religion (OR = 0.843), and knowledge of CPR (OR = 4.734). Conclusion: This study indicated that the strongest predictor is knowledge of CPR. Therefore, it would be helpful to teach CPR nationwide to encourage performing CPR. In addition, effect of CPR education in religious facilities is necessary.

This paper empirically examines various personal characteristics and preferences of HRM (Human Resorce Mamagement) systems using data from 968 R&D professionals in 9 private R&D organizations. It identifies different patterns of reward and career development needs associated with 4 types of R&D professionals, who are categorized by personal characteristics: personality and attitude. A productive leader type shows active personal traits (which encompass high scores of need for achievement, risk-taking propensity, tolerance for ambiguity, and self-efficacy) and positive attitudes (which include high scores of job satisfaction, organizational commitment, and low scores of turnover intention), while a cynical bystander type exhibits passive personal traits and negative attitudes toward a job. A passive adapter, who has passive personal characteristics but positive attitudes, and a frustrated champion, who is active in personality but negative in current job attitude, lie in between them. The results reveal that: 1) These four different types of R&D professionals show differences in their education, age and tenure level, and technical performance. 2) They have different career orientations and problem solving styles. 3) They also exhibit different preferences in performance appraisal criteria and rater, and reward structures. Based on these findings, this study suggests a contingent type of human resource management in terms of selection and staffing of R&D professionals, performance appraisal, incentive systems, and career development plans.

Purpose: There has been an increase in the number of prehospital cardiac arrests due to increases in both cardiovascular diseases and the average age of the population, We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrest. Methods: We studied 57 victims with prehospilal cardiac arrest by EMT's Reports form January to December, 2004. Results: Fifty-seven of 92 victims were trasported with ECG in prehospital cardiac arrest. Ventricular fibrillation(VF)/ ventricular tachycardia was 56.2%, asystole was 33,3%, and pulseless electrical activity(PEA.) was 10.5% in initial rhythm analysis, There weren't attempt CPR in 14.0%. Twenty of the 32(62.5%) were shocked by AED for the adequacy method. There were no statistical differences the transportation time. Conclusion: With the increase in cardiovascular disease and old age, the number out-of-hospital cardiac arrests has risen accordingly. However, there were lack of CPR by bystander, defibrillation, advanced cardiac life support(ACLS) in prehospital stage. To improve the adequancy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.

This research is devoted to increase resuscitation rate of emergency patients, expanding CPR to a pan-national campaigning, revaluating popularity and suitability of the education about the existing CPR(Bystander cardiopulmonary resuscitation) education expansion of 119 EMS. Questionnaire was carried from seven hundred fifty eight residental and students in kyuggi fist area(Southern suwon, Middle suwon, Osan, Young-in) from July 20 to July 30, 2006. The institutional support for CPR education and special eduction institution are not prepared, 52.44% of those have CPR education, according to questionnaire. 39.9% of the educated is from 119 EMS and it is big outcome, 119 EMS efforts in the vortex of poor surroundings. But, 69.76% of the uneducated said they had not chance of CPR education and 19.63% said that the reason is no special eduction institution and information for CPR education. They say that CPR education was carried for only applicants in 119 EMS, without systematic and institutional support, special eduction institution. So, we have to expand the infrastructure, institute CPR education for systematic propagation of CPR education. And we need to make plan constructive public relations, intensify maintaining of CPR educated.

Purpose: Bystander CPR has demonstrated improved survival of out-of-hospital cardiac arrest. The purpose of this study was to evaluate the effects of CPR education in the rural community. Method: One hundred eighty-nine rural laypersons (105 in the experimental group and 84 in the control group) participated in this study. In the experimental group, questionnaires were completed after participating in a small group BLS (Basic Life Support) course. In the control group questionnaires were collected from two rural health service centers. Data were analysed using $X^2$test, independent t-test and paired t-test. Result: There were significant differences in barriers to performing CPR, attitude and intention toward CPR and necessity recognition between the two groups. Conclusion: The proportion of positive attitudes toward CPR and willingness to perform CPR was higher in the experimental group than the control group. CPR education increased anxiety of being sued because of a bad outcome. For future CPR education for laypersons, the reluctance of bystanders to perform CPR should be reconsidered and CPR education should be extended to the rural community.
