  • 국내의 암 발생 변화 추이를 고려해보면, 현재 남성에게 발생하는 전립선암의 비중이 나날이 증가하고 있다. 전립선 암의 경우 림프절이나 뼈에 전이가 되면 90% 이상 사망에 이른다. 따라서 최근 핵의학 분야에서는 전립선 암의 뼈 전이를 보다 정확하게 진단하기 위해 여러 영상기법과 방사성 의약품의 개발이 진행, 소개되고 있다. 본 연구에서는 전립선 암세포의 뼈 전이에 대한 보다 정밀한 영상을 획득하여 진단능을 향상시키는 $^{18}F$-Fluoride PET/CT의 유용성을 알아보고자 한다. 본 연구는 총 33명의 전립선암으로 진단된 환자로서, 평균 $67.8{\pm}10.2$세의 남자를 대상으로 하였다. 동일한 환자에게 각각 전신 뼈 검사(Whole Body Bone Scan; WBBS)와 뼈 양전자 방출 컴퓨터 단층 촬영(18F-Fluoride Positron Emission Tomography/Computed Tomography; $^{18}F$-Fluoride PET/CT)을 시행하였으며, 각 검사에서 나타난 병변을 확인하여 ROC곡선(Receiver Operating Characteristic Curve)을 통해 AUROC (The Area Under an ROC)분석하였다. 또한 두 검사의 민감도와 특이도, 양성예측률과 음성예측률 그리고 두 검사의 정확도를 비교 분석하였다. 총 33명 중 22명의 환자(66.6%)에게서 뼈 전이가 있었으며, $^{18}F$-Fluoride PET/CT에서 모두 우수한 결과치가 나타났다. WBBS의 민감도는 63.6%, 특이도는 81.8%였고, $^{18}F$-Fluoride PET/CT에서는 민감도 100%, 특이도 90.9%로 나타났으며, AUROC를 비교한 결과 WBBS에서 0.778, $^{18}F$-Fluoride PET/CT는 0.942로 분석되었다. $^{18}F$-Fluoride PET/CT는 WBBS에 비하여 높은 민감도와 특이도를 보였으며, 3D 영상 구현으로 암세포의 뼈에 대한 전이성 병소를 더욱 정확하고 명확하게 발견할 수 있었다. 또한 WBBS의 장시간 검사에 비하여 $^{18}F$-Fluoride PET/CT는 상대적으로 단시간에 뼈의 생리적인 변화에 대한 정확한 영상을 얻을 수 있어 환자의 불편함을 최소화 할 수 있었다. 고가 검사비용에 대한 부담을 줄일 수 있다면 $^{18}F$-Fluoride PET/CT를 통해 더욱 정확한 영상을 제공하여 임상에서의 진단능을 향상 시킬 수 있을 것으로 사료된다.

  • This Study was attempted to provide the basic data necessary in the development and introduction of Home Health Nursing System by investigating the recognition and attitude level of Home Health Nursing System. The data were collected by means of questionaires presented to 74 patients who had been admitted in C general hospital in Chon Ju, from June 30, 1997. As the tool for this study, the questionares developed by Kim Yong. Soon, et al (1990) and Han Bok Hee(1993) were modified and supplemented for the aim of this study. The computer was used for data analysis. The items about the charateristics of the subjects and the attitude to the management plan of Home Health Nursing System were represented as the frequency and percentage. The standard deviation and calculation average were produced on the items related to definition, recognition, necessity, expected effect of the attitude of Home Health Nursing System and the items related to admission. The ANOVA test was .used according to the characteristics of variables to analyze the necessity and difference of Home Health Nursing System. The results of this study were as follows 1) The general characteristics of the subjects were as follows ; for sex, man, $58.1\%$ ; for age, 50-59 years, $29.7\%$ ; for the level of education, high school, $51.4\%$ ; $79.7\%$ of them were married; for the family forms, small family, $73.0\%$ ; and $68.9\%$ of them take the monthly income over 100 million won. 2) The characteristics related to admissions of the subjects were as follows ; for clinic, surgical department, $78.4\%$ ; addmission not more then 7days, $47.3\%$ ; for the operation-performance $71.6\%$ of them were experienced; for the admission route, via outpatients clinic, $54.1\%$ ; for waiting period to the admission day, 1-2 days, $71.6\%$. 3) The difficulties comming from the hospitalization were related mostly to the factor that they felt hospital life more inconvenient than home.(3.66) The reasons for the difficulties in the admission which was due to insufficient beds in the hospital was related to the concentration to the general hospital because of 'The Whole National Medical Insurance System'(4.05). 4) On the previous informations about the Home Health Nursing System, those who have heard of only the name were 42 $(56.8\%)$, and on the recognition of it, they thought that it is periodic treatment by the licenced nurses for the recovering pateints after early discharge(3.73). On the attitude about the necessity of Home Health Nursing System, they thought that it is necessary because of the increasing trend of a psychological disease by the change of environment and complexity of the social structure(4.24). On the expected effect of Home Health Nursing System, they answered that it is convinient for the family of the patient to take care of them(4.l8). 5) On the attitude to the management plan of the Home Health Nursing System, those who had intention to participate in the system in the case of systemic support were 42(56.8). In the visiting time, 'visit periodically' and 'visit when the patient needs' were $28(37.8\%)$ respectively. For the application of medical insurance, if possoble, they will use $(91.9\%)$; for the method of payment for the treatment, 'pay by the time required' was $23(31.1\%)$, for the subject of management, 'National public institute must operate' was $33(44.6\%)$. 6) The relationship between the general characteristics of the subjects and the necessity of Home Health Nursing System showed the notable difference in the age (F=3.508, P<0.05) and marrage state (F=5.402, P<.023).

  • The purpose of this study was to examine how dentists perceived dental coordinators including their education, hiring criteria, working condition and job. It's basically attempted to help define the job and role of 5 and to suggest how they should be nurtured. The subjects in this study were dentists at dental hospitals and clinics where dental coordinators were employed among approximately 200 dental institutions in Seoul, Cyeonggi province and Incheon. After a survey was conducted in June 2005, answer sheets from 99 respondents were analyzed. The findings of the study were as follows: 1. Regarding education for dental coordinators, 99.9% of the dentists investigated felt the need for separate education programs for dental coordinators, 42.4% knew what would-be dental coordinators learned about, and 81.8% considered it necessary for them to take intermediate or higher courses. An organization affiliated with the Korea Dental Hygienists Association was viewed as the best institute to educate dental coordinators, and educational institutes that included a department of dental hygiene was looked upon as the second best one. 68.7% believed that dental coordinators should take an official examination to test their qualifications, and concerning educational subsidy, the largest group of the dentists thought that a certain amount of subsidy should be provided. 2. As for coordinator hiring, the top priority was the impression(look) of applicants(55%), followed by adjustability to existing employees(24.5%) and professional competency(17.3%). As to the route of hiring, 41.4 percent, the largest group, reeducated some of existing employees, and dental hygienists were regarded as the best personnels to serve as a coordinator. Concerning job performance, they put the most emphasis on interpersonal relationship, which was followed by executive ability, impression and career, 58.6% the largest group, believed that dental coordinators should have a three-year or higher career to work at a dental institute. 3. As to working conditions, 75.7%, the largest group, paid dental coordinators based on their job performance, and 23.2%, the second largest group, had their pay equal to that of dental hygienists, 88.9% allowed them to determine their own retirement age. 4. In regard to their perception of dental coordinators, the largest number of the dentists considered it necessary for them to keep receiving education(4.29), and the second largest group felt that they served to enhance the image of dental institutes(4.18). The third largest group thought that they contributed to letting patients more satisfied with the quality of dental services. But they tended not to agree that their turnover rate was low(3.04), and they didn't find them to receive appropriate education, either(3.10). 5. The current major job of coordinators associated with customer services was handling appointments with customers(91.9%), treating unsatisfied customers(85.9%), and controling waiting time(84.8%). Regarding self-management, coordinators directed their energy into having good manners(89.9%), acquiring fundamental dental knowledge(84.8%), and learning how to treat customers(83.8%). Concerning hospital affairs handling, they were most responsible for information desk(87.9%), which was followed by receiving(86.9%). As a result of investigating what type of job the dentists hoped dental coordinators to fulfill in consideration of their career, their age and type of investment, the dentists wanted them the most to speak a foreign language, which belonged to the field of self-management.

  • $^{11}C$-Acetate PET/CT는 간에 관련된 병변을 찾아내는데 있어 유용성이 있으며, 이에 대한 예민도는 87.3%에 이른다. 이에 반해 $^{18}F$-FDG PET/CT의 예민도는 47.3%이며, $^{18}F$-FDG와 $^{11}C$-Acetate PET/CT 검사를 동시에 사용하는 경우 예민도는 100%로 보고된바 있다. 하지만 $^{11}C$-Acetate PET/CT검사에서 췌장, 비장의 정상섭취로 인해 $^{18}F$-FDG PET/CT검사에 영향을 줄 수 있어 정확한 진단에 혼란을 야기시킬 수 있다. 본 연구는 이러한 두 방사성의약품의 사용으로 인하여 영상에 얼마나 영향을 주는지에 대해 당일 검사법과 양일 검사법 간의 비교 분석을 통해 유용성을 확인하는데 목적이 있다. 본 연구는 2007년 12월부터 2009년 7월까지 본원에서 간암 진단을 받고 PET/CT 검사를 시행한 환자 46명을 대상으로 하였다(남자 35명, 여자 11명, 평균연령: $54{\pm}10.6$세, 연령 범위: 29~69세). 검사에 이용된 장비는 Biograph TruePoint 40 PET/CT이며, 당일 검사법으로 검사한 21명에게는 $^{11}C$-Acetate PET/CT 검사를 먼저 시행하고 약 1시간 후에 곧바로 $^{18}F$-FDG PET/CT 검사를 시행하였다. 양일 검사법으로 검사를 시행한 25명에게는 1일째 $^{11}C$-Acetate PET/CT검사를 시행하고, 2일째 $^{18}F$-FDG PET/CT 검사를 시행하였다. 두 검사법 간의 $^{18}F$-FDG 영상에서 췌장과 비장에 동일한 관심영역을 설정하고 표준섭취계수를 측정하여 비교 평가하였다. 통계 분석은 SPSS Ver. 17을 사용하였으며, unpaired t-test를 통하여 두 검사법 간의 통계적 유의성을 확인하였다. 각각의 검사법으로 시행한 환자의 영상을 분석한 결과, 양일 검사법으로 검사를 시행한 환자의 췌장 부분의 표준섭취계수 평균${\pm}$표준편차는 두부 $1.62{\pm}0.32$ g/mL, 체부 $1.57{\pm}0.37$ g/mL, 미부 $1.49{\pm}0.33$ g/mL, 비장은 $1.53{\pm}0.28$ g/mL였다. 당일 검사법으로 검사를 시행한 환자의 췌장은 두부 $1.65{\pm}0.35$ g/mL, 체부 $1.58{\pm}0.27$ g/mL, 미부 $1.49{\pm}0.28$ g/mL, 비장은 $1.66{\pm}0.29$ g/mL로 나타났다. 당일 검사법과 양일 검사법 간의 췌장과 비장에서의 표준섭취계수는 통계적으로 유의한 차이를 보이지 않았으며 (p<0.05), PET/CT 영상분석에서도 위양성으로 오인할 수 있는 높은 섭취는 보이지 않았다. 본 연구를 통해서 하루 동안 $^{11}C$-Acetate와 $^{18}F$-FDG PET/CT 검사를 시행하여도 $^{18}F$-FDG 영상에서 $^{11}C$-Acetate의 영향으로 인해 표준섭취계수의 과대평가가 일어나지 않는다는 것을 알 수 있었고 이는 표준섭취계수의 측정값을 통해 통계적으로 유의성을 확인할 수 있었다. 앞으로 $^{11}C$-Acetate가 상용화될 경우 $^{18}F$-FDG와 당일 검사법을 이용하여 간질환의 진단에 있어 PET/CT 검사의 진단능을 향상시킬 수 있고 위 결과를 토대로 두 방사성의약품의 간섭영향 없이 하루에 검사를 완료할 수 있으며, 대기시간을 단축하여 환자의 만족도를 높일 수 있을 것으로 사료된다.
