The purpose of this study was to identify knowledge of universal precautions and its performance in practice. The research was conducted from November 2 to 30, 1998. A total 515 student nurses ; 249 from a baccalaureate nursing college and 266 from second and third year of a 3-year community nursing college were surveyed. The results are as following : 1. The average score for universal precautions knowledge was 270.41$\pm$19.43/300(range 150-300). The results showed that 99.2% of students avoid injury from used needles, 98.6% answered that they always wash their hands if they had contact with the patient's blood and they always dispose of used needles in special collectors (97.7%) for needles. But, 39.2% responsed that they dispose of used needles after recapping them. 2. The average score for universal precautions knowledge of the senior students in the 4-year college was the highest (277.65$\pm$13.99). 3. The average score for the performance of universal precautions knowledge was 53.18 $\pm$5.91(range 14-70). The items : ‘I cautiously avoid injury from the used needles’(4.92$\pm$0.33), ‘I always wash my hands if there has been contact with the patient's blood’(4.91$\pm$0.34), and ‘I always disposed of used needles in the appropriate collector’(4.89$\pm$0.42) showed the highest performance. However ‘I always dispose of used needles after recapping them’(2.19$\pm$1.39) and ‘I always use protection goggles when in danger of contamination’(2.19$\pm$1.20) showed low performance level. 4. The highest average score for universal precautions performance was shown among the second year students in 3-year nursing college (54.19$\pm$6.92) between the groups. It showed that the level of the universal precautions performance was higher for those who had education on university precautions prior to performance of the universal precautions than for those without any prior education. 5. The percentage of students who reported the experience of direct contact with patients' blood and/or body fluids was 42.30%. The experience of direct contact with blood and/or body fluids of the educational group was significantly higher than those were not educated. 6. The most frequent cause of the direct contact was ‘needle pricking and/or skin cut’(63.04%). The most frequent substance with which the students contact was ‘blood’(59.85%). The majority of the sample had answered that the mode of contamination was ‘unknown’(63.54%). The majority of the sample answered that strategies used after contamination included ‘washing with soap’(33.61%). Reviewing the chart of patients or asking other health professionals(28.85%). 7. The number of students who had the experience of a needle stick and/or skin cut was 145(28.16%). The clinical practice places where the incidents occurred were mainly in the internal medicine unit (45.07%) and the surgical unit (31.92%) followed by the intensive care unit and the emergency unit in order. The experience of a needle stick and/or skin cut happened during on intra-muscular injection 47.34% and intravenous injection 21.81%. The causes of the needle stick and/or skin cut were ‘putting the needle cap back on 77(35.81%)’. The number of students who took an appropriate post management blood test and/or vaccination was 27(18.62%). 8. The Pearson Correlation Coefficient between the knowledge of universal precautions and performance of universal precautions in practice showed a positive correlation.

It has been believed that cancer is an omnious factor threatening the future and life itself. Patients having the disease experience anxiety, fear, feeling of weakness, depression and feelings of uncertainty and hopelessness. Most cancer patients, however, have expectations of possible recovery and a better future, very different from the patients who feel hopeless. Therefore. hope allows people to respond effectively to the fatal disease they have and prevents them from detoriorating physically and spiritually, positively influencing their survival, response to treatment and sense of security. Studies previously performed showed that hope is positively correlated with social and family supports, self-esteem, spiritual well-being, responsive action, health promotion behavior and quality of life. Thus, the study attempted to provide basic information on nursing cancer patients by investigating their levels of hope and determining predictive factors which influence hope. For the study 200 cancer patients in two university hospitals located in Pusan were sampled as subjects. Data were collected for twenty nine days from Feburary 1, 1999 to March 1. Instrumets for the study included 10 items from the self-esteem scale by Rosenberg (1965), 39 hope measurements by Kim and Lee(1965), 16 of the social support scale by Tae(1986) and 16 of the general characteristics scale, all of which totaled 81 items. The data were analyzed using the SPSS program. General characteristics of the investigated based on numbers and percentage. Hope, self-esteem and social support were analyzed using means, minimum, maximum and standard deviation. Relations among the foregoing three factors were analyzed using Pearson' correlation coefficient. Levels of hope in cancer patients were determined using t-test, ANOVA and Scheffe test. Predictive factors influencing hope were investigated using multiple stepwise regression analysis. Results of the study are summarized as follows: 1. An average level of hope was $185.55{\pm}23.39$ points(96 min. and 234 max.) 2. Levels of hope showed a significant difference among them according to sex (t=-3.69, P=.000), age(F=4.714, P=.000), job(F=3.247, P=.008), monthly income (F=6.113, P=.003), treatment charge (F=3.796, P=.011), supportive resources (F=10.554, P=.000), diagnosis(F=2.287, P=.029), perceived health status(F=22.184, P=.000), level of pain(F=3.334, P=.021), religion (F=4.911, P=.001) and religion's effect in life (F=11.706, P=.000), 3. For the subjects, self-esteem and social support were $38.32{\pm}7.21$(13 min, and 50 max.) and $52.97{\pm}8.49$points(28 min, 80 max.). Concerning social support, average levels of family support and medical support were found $35.95{\pm}6.05$(18 min, and 40 max) and $27.02{\pm}4.99$ points(20 min and 40 max). The hope the cancer patients showed significant correlations with self-esteem (r=.588, P=.000), family support(r=.224, p=.001) and medical support(r=.221, P=.002). 4. The five variables related to hope (self-esteem, religion's effect in life, perceived health status, social support and age) accounted for 54.2 percent of the hope level; especially, self-esteem was the highest at 34.6%. As shown in the above results, predictive factors which most influence hope in cancer patients were self-esteem and religion's effect of life. Therefore, nursing interventions to increase self-esteem should be developed. Regarding religion's effects, studies on spiritual aspects should be carried out in a way that contributes to promotion of hope.

Industrial shift workers feels suffer mental stresses which are caused by unfamiliar day sleep, noisy environment, sleeping disorder by bright light, unusual contacts with family, difficulty in meeting with friends or having formal social meetings and other social limitations such as the use of transportation. Such stresses influence health of the workers negatively. Thus the health promotion policy for shift workers should be made considering the workers' ways of living and shift work specially. This study attempted to provide basic information for development of the health promotion program for industrial shift workers by examining predictive factors influencing health promotion behaviors of those workers. In designing the study, three power generation plants located in Pusan and south Kyungsang province were randomly selected and therefrom 280 workers at central control, boiler and turbine rooms and environmental chemistry parts whose processes require shift works were sampled as subjects of the study. Data were collected two times from September 17 to October 8, 1999 using questionnaires with helps of safety and health managers of the plants. The questionnaires were distributed through mails or direct visits. Means for the study included the measurement tool of health promotion behavior provided by Park(1995), the tool of self-efficacy measurement by Suh(1995), the tool of internal locus of control measurement by Oh(1987), the measurement tool of perceived health state by Park(1995) and the tool of social support measurement by Paek(1995). The collected data were analyzed using SPSS program. Controlling factors of the subjects were evaluated in terms of frequency and percentage ratio Perceived factors and health promotion behaviors of the subjects were done so in terms of mean and standard deviation, and average mark and standard deviation, respectively. Relations between controlling and perceived factors were analyzed using t-test and ANOVA and those between perceived factors and the performance of health promotion behaviors, using Pearson's Correlation Coefficient. The performance of health promotion behaviors was tested using t-test, ANOVA and post multi-comparison (Scheffe test). Predictive factors of health promotion behavior were examined through the Stepwise Multiple Regression Analysis. Results of the study are summarized as follows. 1. The performance of health promotion behaviors by the subjects was evaluated as having the value of mean, $161.27{\pm}26.73$ points(min.:60, max.:240) and average mark, $2.68{\pm}0.44$ points(min.:1, max.:4). When the performance was analyzed according to related aspects, it showed the highest level in harmonious relation with average mark, $3.15{\pm}.56$ points, followed by hygienic life($3.03{\pm}.55$), self-realization ($2.84{\pm}.55$), emotional support($2.73{\pm}.61$), regular meals($2.71{\pm}.76$), self-control($2.62{\pm}.63$), health diet($2.62{\pm}.56$), rest and sleep($2.60{\pm}.59$), exercise and activity($2.53{\pm}.57$), diet control($2.52{\pm}.56$) and special health management($2.06{\pm}.65$). 2. In relations between perceived factors of the subjects(self-efficacy, internal locus of control, perceived health state) and the performance of health promotion behaviors, the performance was found having significantly pure relations with self-efficacy (r=.524, P=.000), internal locus of control (r=.225, P=.000) and perceived health state(r=.244, P=.000). The higher each evaluated point of the three factors was, the higher the performance was in level. 3. When relations between the controlling factors(demography-based social, health-related, job-related and human relations characteristics) and the performance of health promotion behaviors were analyzed, the performance showed significant differences according to marital status (t=2.09, P= .03), religion(F=3.93, P= .00) and participation in religious activities (F=8.10, P= .00) out of demography-based characteristics, medical examination results (F=7.20, P= .00) and methods of the collection of health knowledge and information(F=3.41, P= .01) and methods of desired health education(F=3.41, P= .01) out of health-related characteristics, detrimental factors perception(F=4.49, P= .01) and job satisfaction(F=8.41, P= .00) out of job-related characteristics and social support(F=14.69, P= .00) out of human relations characteristics. 4. The factor which is a variable predicting best the performance of health promotion behaviors by the subjects was the self-efficacy accounting for 27.4% of the prediction, followed by participation in religious activities, social support, job satisfaction, received health state and internal locus of control in order all of which totally account for 41.0%. In conclusion, the predictive factor which most influence the performance of health promotion behaviors by shift workers was self-efficacy. To promote the sense, therefore, it is necessary to develop the nursing intervention program considering predictive factors as variables identified in this study. Further industrial nurses should play their roles actively to help shift workers increase their capability of self-management of health.

PET/CT 기기의 설치가 증가함에 따라 PET/CT 검사 시감쇄 보정을 위한 CT 검사 역시 증가하여 검사 과정에서 피폭 선량이 증가 되고 있어 의료 피폭의 저감 대책을 포함한 방사선 안전 관리의 체계적인 구축이 필요하다. 본 연구에서는 PET/CT 검사에서의 환자 선량 데이터베이스를 구축하여 환자 선량 저감을 위한 초석을 세우기 위해 CT 선량 측정 프로그램을 사용하여 CT를 사용한 투과 스캔 시 환자가 받는 CT의 예측 유효 선량을 비교 분석하였다. BIO40, BIO16, DSTe8 에서 $^{18}F$-FDG PET/CT 검사를 시행한 180명을 대상으로 하였다. 각 기기 별로 남, 여 30명씩 선량의 평균을 분석하였다. 자동 노출 제어 시스템으로 선량 조절 시 가장 큰 영향을 줄 수 있는 환자의 체중 별로 50 kg미만, 50-60 kg 미만, 60 kg 이상 세 집단으로 나누어 선량의 평균을 분석하였다. CT-Expo v1.7과 ImPACT v1.0을 사용하여 선량 측정을 한 값을 비교 분석하고 체중과 유효 선량의 상관관계를 분석하였다. BIO40에서 검사한 환자의 유효 선량을 CT-Expo v1.7과 ImPACT v1.0을 사용하여 예측하였을 때, 남자 환자 30명은 각각 $6.46{\pm}1.18$ mSv, $6.54{\pm}1.21$ mSv, 여자 환자 30명은 각각 $6.29{\pm}0.97$ mSv, $5.87{\pm}1.09$ mSv 이었다. BIO16 에서 검사한 환자의 유효 선량은 남자 환자 30명은 각각 $9.36{\pm}1.96$ mSv, $8.36{\pm}1.69$ mSv 여자 환자 30명은 각각 $10.02{\pm}2.42$ mSv, $8.43{\pm}1.89$ mSv 이었다. DSTe8에서 검사한 환자의 유효 선량은 남자 환자 30명은 각각 $9.36{\pm}1.96$ mSv, $9.74{\pm}2.55$ mSv, 여자 환자 30명은 각각 $9.05{\pm}2.27$ mSv, $9.19{\pm}2.29$ mSv 이었다. 각 기기에서 검사를 시행한 환자의 체중에 따른 환자의 선량을 비교하기 위해, BIO40에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50~60 kg 미만, 60 kg 이상으로 체중별로 세 개의 집단으로 나누어 환자 선량을 측정하였다. CT-expo v1.7로 측정을 하였을 때 각각 $6.05{\pm}1.77$ mSv, $6.18{\pm}1.05$ mSv, $6.80{\pm}1.06$ mSv이었고 ImPACT v1.0으로 측정했을 때 각각 $5.06{\pm}1.46$ mSv, $5.72{\pm}0.86$ mSv, $6.42{\pm}0.96$ mSv이었다. BIO16에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50-60 kg 미만, 60 kg 이상으로 체중 별로 나누어 환자 선량을 측정하였다. CT-Expo v1.7로 측정을 하였을 때 각각 $7.74{\pm}0.66$ mSv, $8.58{\pm}0.93$ mSv, $10.88{\pm}1.32$ mSv이었고 ImPACT v1.0으로 측정했을 때 각각 $6.60{\pm}0.54$ mSv, $7.45{\pm}0.69$ mSv, $9.43{\pm}1.11$ mSv이었다. DSTe8에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50-60 kg 미만, 60kg 이상으로 체중 별로 나누어 환자 선량을 예측하였다. CT-Expo v1.7로 측정했을 때 각각 $5.03{\pm}0.95$ mSv, $8.25{\pm}1.66$ mSv, $10.33{\pm}1.68$ mSv 이었고 ImPACT v1.0으로 측정했을 때 각각 $5.20{\pm}1.01$ mSv, $8.51{\pm}1.53$ mSv, $10.9{\pm}1.87$ mSv이었다. 체중과 유효 선량의 상관관계를 분석하였을 때 CT-Expo v1.7과 ImPACT v1.0에서 Pearson 정률 상관계수가 각각 0.743, 0.692으로 매우 강한 양의 상관관계가 있었다. 피폭 선량의 예측이 필요할 경우 이와 같은 상용화된 선량 평가 프로그램을 사용하면 Phantom 연구를 시행하지 않더라도 유효 선량의 예측 및 평가가 가능하고, CT 선량 관리를 위한 기초 자료를 수집하는데 활용 될 수 있을 것으로 생각된다.

The problem addressed by this study was to determine the effect of nurse - patient agreement on the means to achieve nursing goals in the early postpartum period of primiparous mothers. It was hypothesized that the experimental treatment would result in hegher self-confidence and satisfaction in maternal role performance. This purpose was to contribute to the planning of nursing care to enhance self- confidence and satisfaction in maternal role performance and to the development of relevant nursing theory. Especially, the early postpartum period is crucial toward in recovery from childbirth and attainment of the maternal role. Maternal role attaintment is a complex social and cognitive process of stimulus -response accomplished by learning. Most women attain the maternal role sucessfully. But, some primiparous mothers experience difficultites in attainment of the maternal role due to lack of experience and knowledge. Self-confidence and satisfaction in maternal role performance are important factors in attainment and adjustment to the maternal role (Mercer, 1981a, 1981b ; Lederman, Weigarten, and Lederman, 1981 :Bobak and Jensen, 1985). Nursing is defined as behaviors of nurses add patients that attain nursing goals through action, reaction, interaction, and transaction. For attainment of nursing goals, active participating transactions must occur by agreement on the means to achieve those goals through nurse -patient mutual goal setting and establishment of their active relationships(King, 1981, Ha, 1977). Based on King's theory of goal attainment (1981), this stuy was planned as a non-equivalent control group, non -synchronized quasi -experimental design using agreement on the means to achieve nursing goals in early postpartum as the experimental treatment. The data were collected from July 20 to Sep. 1, 1991 by questionnaires with 60 primiparous mothers planing to breast feed after normal deliveries at W hospital in Pusan, Korea. The subjects were divided into a control group(conventional group) -those admitted from July 20 to Aug. 12, and an experimental group(agreement group) - those admitted from Aug. 13 to Sep. 1. The instument for agreement on the means to nursing goals in the early postpartum period included five steps - identification of disturbances of problems through action, reaction, and interaction with primiparous mothers : mutual early postpartal nursing goal setting : exploration of the means to achieve goals ; agreement on the means (self- care, ealry maternal -infant contact, performance of mothering behavior, and communicating about the infant's behavior and health condition) : implementation of the means. This instrument was developed on the basis of King's elements that lead to transactions in nurse-patient interactions. Lederman et al's (1981) scale for Confidence in ability to cope with tasks of motherhood and Lederman et al's(1981) scale for Mother's satisfaction with motherhood and infant care were used to measure self-confidence and satisfaction in maternal role performance ·with the subjects immediately after admission and on the day of discharge. Self-care performance in the experimental group was measured by self -evaluation tool developed by the investigator from the literature concerned. The tools to measure Pelf-confidence and satisfaction in maternal role performance, and the tool to measure self-evaluation of self-care performance were tested for internal reliability. Cronbach's Alphas were 0.94, 0.94, and 0.63. The data were analysed by using in S.P.S.S. computerized program and included percentage, x²-test, t-test, ANOVA, and Pearson Correlation Coefficient. The conclusions obtained from this study are summerized as follows : 1. The degree of self-confidence in maternal role performance of the total subjects group measured before the experimental treatment was above average with a mean score of 2.77(range 2.14-3.64). Out of 14 items, those with relatively high mean scores were ‘I would like to be a better mother than I am’(3.95), and ‘I have my doubts about whether I am a good mother’(2.87). Those with low mean scores were ‘I know that my baby wants most of the times’(2.28), ‘When the baby cries, I can tell what she /he wants’(2.37), and ‘I have confidence in my ability to care for the baby’(2;50). That is, the self - confidence of Primiparous mothers was considerably high in mothering, but rather low in activities concerning the infant care and understanding of the infant behavior. The degree of satisfaction in maternal role performance of the total subjects group measured before the experimental treatment was high with a mean score of 3.18(range 1.92-3.92). Out of 13 items, those with relatively high mean scores were ‘I am glad 1 had this baby now’(3.75), ‘I play with the baby between feedings when s/he is awake and quiet’(3.67), and ‘I enjoy being a mother’(3.27). Those with low mean scores were ‘I am upset about having too many responsibilities as a mother’(2.78), ‘It bothers me to get up for the baby at night’(2.82), and ‘I get annoyed if the baby frequently interrupts my activities’.(2.82), That is, the satisfaction of primiparous mothers was considerably high in mothering and infant care, but rather low in restraints in time or on the mother's self accomplishment and development. 2. Agreement on the means to achieve nursing goals in the early postpartum period included process of mutual goal setting, exploration of the means to achieve goals, and ahreement in concert means to achieve goals based on the mothers' condition, concerns, self-perception of the nurse - patient interactions. In the process of agreement, there was agreement that the means to achieve goals should be through trust and establishment of active relationships with the nurse through identification of problems according to planned nursing goals and active interaction, such as explanations, teaching, changing of opinions, acceptance or rejection of explanations, and proposing of questions. Therefore agreement on the means to achieve nursing goals in the early postpartum period appears to be an effective nursing intervention for primiparous mothers. 3. The degree of self- confidence in maternal role performance of the exprimental group was higher than that of the control group(t＝3.95, p＜0.01). Out of 14 items, those with higher score in the experimental group were ‘I would like to be a better mother than I am’(t＝1.93, p＜0.05), ‘I know that my baby wants most of the times’(t＝2.75, p＜0.01), ‘When the baby cries, 1 can tell what she/he wants’(t＝2.10, p＜0.05), ‘I have confidence in my ability to care for the baby’(t＝3.72, p＜0.01), ‘I trust my own judement in deciding how to care for the baby’(t＝1.96, p＜0.05), ‘I feel that I know my baby and what to do for him /her’(t＝2.44, p＜0.01), ‘I am concerned about being able to meet the baby's needs’(t＝2.87, p＜0.01), ‘I know what my baby likes and dislikes’(t＝3.26, p＜0.01), ‘I don't know to care for the baby as well as I should’(t＝2.07, p＜0.05), and ‘I am unsure about whether I give enough attention to the baby’(t＝3.04, p＜0.01), That is, the degree of self-confidence in mothering, activities concerning infant care, and understanding of infant behavior of the experimental group was higher than that of the control group. Therefore, the first hypothesis, that the degree of self-confidence in maternal role performance of the experimental group would be higher than that of the control group, was supported(t＝3.95, p＜0.01). 4. The degree of satisfaction in the maternal role performance of the exprimental group was higer than that or the control group(t＝2.31, p＜0.05). Out of 13 items, those with higher score in the experimental group were ‘I am glad I had this baby now’(t＝2.29, p＜0.05), ‘I enjoy taking care of the baby’(t＝2.4g, p＜0.01), ‘It is boring for me to care for the baby and do the same thing over and over’(t＝2.87, P＜0.01), ‘I am unhappy with the amount of time I have for activities other than childcare’(t＝2.51, p＜0.01), and ‘When bathing and diapering the baby, I would like to be doing something else’(t＝2.43, p＜0.01). That is, the degree of satisfaction in mothering, infant care, and restraints in time of on the mother's self accomplishment and development in the experimental group was higher than that of the control group. Therefore, the second hypothesis, that the degree of satisfaction in maternal role performance of the experimental group would be higher than that of the control group, was supported(t＝2.31, p＜0.05). 5. The third hypothesis, that the higher the degree of satisfaction in materenal role performance, the higher the degree of self-confidence in materenal role performance in the experimental group, was supported (r＝0.57, p＜0.01)
