This study was designed to provide the base of nursing intervention that could help apheresis blood-donors to promote self-efficacy effectively by analyzing critical factors that influence on this. The subjects recruited for the research were 468 persons who participated in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June, 2002 using questionnaires. Data were analyzed by t-test, ANOVA, Scheffe test, and stepwise multiple regression. The results were as follows. 1. The mean self-efficacy score on the questions related to blood donation was $32.9\pm5.1$, indicating that blood donors have above the mean level of self-efficacy related to blood donation. 2. The self-efficacy score was significantly higher for the group of persons who have more than 5 times of experiences in blood donation than others who have only one experience. 3. The critical factors that influence self-efficacy related to donation were the marital status, educational level. and previous experiences of whole blood donation, while the critical factor that influence on general self-efficacy was previous experiences of whole blood donation. Therefore, it is necessary to establish more effective and organized nursing intervention strategies that can promote the self-efficacy of apheresis blood-donors.

This study was designed to provide a base for nursing intervention to help apheresis blood-donors to perform health promotion behavior effectively by surveying their health promotion behavior and by analyzing the critical factors. The study subjects were 468 participants in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June. 2002. by questionnaire. Data were analyzed by t-test, ANOVA. Scheffe test, Pearson correlation coefficient. and stepwise multiple regression. The results were as follows. 1. The degree of performance of health promotion behavior of the subjects was a total average score of $152.9\pm21.5$ points and a mean score of 2.7 points. The highest score was 'I have a good relationship with others' in the factor of self-actualization and interpersonal support. The lowest score was 'I have my blood pressure checked regularly' in the factor of health responsibility. 2. Considering the classification according to the subjects' general characteristics. the health promotion behavior score was significantly higher for soldiers than high school students, for religious believers than atheists. and for high class economic status than mid and low class economic status. Also the health promotion behavior score was higher for those who had made more than five blood donations than those who had made zero or one donation. and for those who had made more than four blood donations than for those who had made less than four blood donations in the previous times of apheresis blood donation. The score was also higher for those not having a relationship with recipient than those having a relationship. 3. The self-efficacy related to donation. general self-efficacy and self-esteem had a significant correlation with the performance in health promotion behavior. 4. The critical factors that influenced the health promotion behavior were explained by $35.6\%$ of the general self-efficacy and by $40.2\%$ of the total of self-efficacy related to donation, and previous times of apheresis blood donation. The health promotion behavior score of apheresis blood-donors differed according to job, religion, economic status, previous times of whole blood donation, previous times of apheresis blood donation, and relationship with recipient. The health promotion behavior and self-efficacy related to donation, general self-efficacy, and self-esteem showed significant positive correlation with one another. The general self-efficacy, self-efficacy related to donation, and previous times of apheresis blood donation appeared to be the significant predictive factors of health promotion behavior. Therefore, from these study results, it is necessary to establish more effective and organized nursing intervention strategies for the health promotion behavior of apheresis blood-donors.

This study was designed to provide basic strategies of nursing intervention in order to keep and obtain healthy, responsible and regular donors by investigating and analyzing relationships of health promotion behavior. self-efficacy and self-esteem of blood-donors. The subjects collected for the research were four hundred and sixty-eight individuals who participated in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June, 2002 using questionnaires. The results were as follows. 1. The proportion of subjects who have not had previous experience of whole blood-donation was $13.7\%$, while the proportion of subjects who have had two times previous experiences was $16.2\%$ and over five times was $30.6\%$. 2. Mean score of health promotion behavior was 2.7 (range 1-4), self-efficacy was 3.8 (range 1-5) and self-esteem was 3.3 (range 1-4), which showed higher than middle. 3. There was positive significant relationship between the number of blood-donation and health promotion behavior as well as the number of blood donation and self-efficacy. 4. Positive significant relationship existed between the number of whole blood-donation and the number of apheresis blood-donation. Therefore, to increase recurrence of blood-donation. it is necessary to establish more effective and organized nursing intervention strategies that can promote the health promotion behavior, self-efficacy and self-esteem of blood-donors.

혈소판제제는 출혈질환이나 혈소판의 기능장애 치료를 위해 사용되고 있다. 혈소판성분채집술은 혈액성분채집기를 사용하여 혈소판 성분을 채집하는 방법으로, 성분채집혈소판의 질 평가에는 다양한 지표들이 이용되고 있다. 채집된 혈소판의 생산성은 채집효율(collection efficiency)과 채집률(collection rates)로 평가되고 보관된 혈소판의 질은 in vitro 상에서 시각적 외양, 대사활성도, 양, 혈소판 수, 백혈구 수, 미세입자(microparticles), 그리고 다양한 혈소판 활성 표지자들로 평가된다. 혈소판 활성 표지자들은 여러 연구분야에서도 이용되고 있다. 수혈된 후의 혈소판의 질은 교정증가치(corrected count increment)와 혈소판회복퍼센트(percentage platelet recovery)로 평가된다. 본 논문은 혈소판성분채집술의 채집과정, 사용되는 장비, 성분채집혈소판의 질, 전반적인 효율성, 그리고 질평가 지표들에 대한 리뷰(review)와 함께 다른 혈액성분채집기 간의 기능의 차이점을 비교하였고, 또한 혈소판성분채집술은 구연산염 항응고제에 의한 부작용을 일으킬 수는 있지만 전혈 헌혈시에 실신의 전구증상이나 실신을 일으킬 위험이 있는 헌혈자들에게는 더 안전한 방법임을 보여주고 있다.
