핵의학 간담도 검사 시, 담낭의 수축력을 정량적으로 평가하기 위하여 지방식(fatty meal)을 이용한 전면상에서의 담낭박출률(gallbladder ejection fraction ; GB EF%)을 진단에 이용하고 있다. 하지만, 담낭과 다른 구조물이 전면상에서 겹쳐질 경우, 담낭 박출률 평가가 정확히 이루어지지 않는다. 이러한 오차를 줄이기 위해 본 연구에서는 전면상과 우측 측면상에서 계산한 GBEF%의 유의한 차이가 있는 지 알아보고자 한다. 본원에 내원한 임의의 환자 50명을 대상으로 $^{99m}Tc$-Mebrofenin 370 MBq를 정맥주사 후 간담도 검사를 실행하였다. 검사는 SKYLIGHT(Philips, United States)을 이용하여 10분, 20분, 30분, 60분, 그리고 지방식(치즈와 우유)을 시행하고 30분 후에 90분 째, 전면상과 우측 측면 영상을 획득하였다. JETstream workspace 프로그램에서 60분째와 90분째 전면상과 우측 측면상에서 GBEF%을 구하였다. 보다 정확한 관심영역 설정을 위해 CT영상을 참고하였고, 4명의 방사선사가 동일한 영상에서의 GBEF%을 구하여 평균값을 계산하였다. 통계분석프로그램SPSS version23(SPSS Inc. USA)을 이용하여 전면상과 우측 측면상에서 GBEF%의 차이에 유의한 차이가 있는지 평가하였다. 무작위 50명 환자의 전면상에서 GBEF%의 평균값은 63.2고, 우측 측면상에서 GBEF%의 평균값은 62.7으로 전면상 대비 우측 측면상에서 0.5% 감소하였다. 전면상과 우측 측면상에서 GBEF%의 대응표본 t-검정 결과 P>0.05으로 유의한 차이가 없었다. 이를 통해 전면상에서 담낭과 다른 구조물이 분리되지 않아 담낭박출률의 오차가 발생하는 경우, 우측 측면상을 이용하여 GBEF%을계산하면 보다 더 정확한 담낭박출률이 평가되는 것으로 사료된다.

This study aims to investigate the use state of the health service computerization system in the occupational nursing field and the occupational nursers' satisfaction level, and provide basic data to promote the development of the health service computerization system for the nursing field. For this study, a questionnaire was provided to 118 occupational nurses who belong to Busan and Gyeongnam branches of KAOHN(Korean Association of Occupational Health Nurses) for 2 months (from Dec. 1, 2002 to Jan. 31, 2003). A tool of Choi Yong-Heui(2000) was used to investigate the satisfaction level of using the health service computerization system. The collected materials were analyzed in real number and percentage, average and standard deviation, t-test and ANOVA by using the SPSS WIN 10.0 program. This study is summarized as follows: 1. The average age was $31.99{\pm}5.58$ old in this study. The married were 54.2%. Participants who graduated from a junior college was 76.9%. The average service period was $4.48{\pm}4.68$ years. In service types, 79.7% of participants served in a health care center. The average service period was $3.22{\pm}2.89$ years. The service place which had 1000 workers or more was 35.6%. 2. Only 20.3% of participants in this study had a computer use education. 3. The field who participants used mostly was communication/internet, $3.29{\pm}.85$ hours in average. 4. 97.1% of occupational fields had computers and peripheral devices: 71.4% in pentium computer, 42.8% in the hard disk capacity of 20-29GB, 60.0% in 15 inch monitors, 86.2% in printers, 18.1% in digital cameras, 12.4% in LAN, and 9.5% in scanners. 80.1% of the occupational fields which were objects of study could use communication. 5. The occupational fields which did not introduced the health service computerization system were 62.8%. The main cause was attributable to entrepreneurs' insufficient recognition 66.6%. 51.5% of the entrepreneurs did not have an introduction plan. 37.2% of participating companies had the health service computerization system. 56.4% of them introduced it since the year 2000. 81.6% of the introduction motivation aimed to the efficiency of health service. The most issue upon introduction was insufficient understanding of a person in charge - 25.6%. The in-house development of the system covered 56.4%. 61.5% of the participants accepted their demands from the first stage of development. The direct effect of computerization showed the increase of 25.9% in the quickness and continuity of service treatment, and 25.9% in the serviceability of statistical treatment. 6. 22.0% of the participants had a computerization system use education. 69.2% of them had a in-house education. An educational method by nurses who used the computerization system was 76.9%. 92.3% of the education was helpful for practical duties. 7. An analysis of the computer use by health service fields showed that the medicine management in a health management field was 15.9%. the work environment measuring management in a work environment filed was 32.9%. the employment. general and special examination management in a heal th management field was 61.1 %. the various reports management in an administrative field was 64%. the health education data preparation management in an educational field was 58.0%. and the medicine and expendables management in an equipment management field was 51.6%. An analysis of the computerization system use showed that the various statistical data manage in a health management field was 13.0%. the work environment measuring management in a health management field was 34.8%. the personal disease management in a health management field was 51.9%. the heal education data preparation management in an educational field was 54.5%. and the equipment management of health care centers in an equipment management field was 52.6%. 8. 31.6% of the participants wanted that health service computerization system would include the generals of health services. 42.4% of the participants thought that first of all. the aggressive interest and investment of employers were required to build the health service computerization system. 9. The participants' satisfaction level on the computerization system use was $3.51{\pm}.57$ points. An analysis by each factor showed $3.62{\pm}.68$ points in a service change factor. $3.15{\pm}.63$ points in a computer program use factor, and $3.45{\pm}.71$ points in a continuous computerization use factor. 10. An analysis of the computerization system use by general characteristics of participants showed that the married (p = .022) had the satisfaction level higher than the unmarried. 11. The satisfaction level of the computerization system use by participants' computer use ability tended to be higher in proportion to the increase of computer use abilities in spreadsheet (F=2.606. p=.048). presentation (F=3.62. p=.012) and communication/internet(F=2.885. p=.0321. Based on the study results mentioned above. I will suggest as follows : The nationwide enlargement and repetition study is required for occupational nurses who serve in occupational nursing fields. The computerization system in a health service field is inferior comparing with other fields. The computerization system standard by business types and characteristics should be prepared through employers's aggressive participation and national support. Therefore various statistical data which occurs in occupational fields will be managed systematically and efficiently. A regular and systematic computer education plan for occupational nurses in charge of health services in the filed is urgently required to efficiently manage and improve the health of on-site workers.
