This study is to make a foundamental abstract and the practical use of PACS in de-partment of radiology. A health demand has be extend that is scientization and popularization of medical skile. also medical eguipment, there fore, a inspection demand has being suddne increase of depantmental radiolgy. A dimension of this sort a PACS (picture Archiving and Communications systems) is Stroage and Care for immediate of patiental image also clinical information, and then the PACS can make offer medical service of good quality, because of that is total in-ormation of patient deliver to every clinical section without delay.

방사선 강내치료를 위한 소조사면 전자선 cone의 선량분포 특성
나수경, 홍시영, 박병섭 김천대학교 2000 김천대학교 논문집 Vol.21 No.-
The intracavitary cones were designed which were made of stain-less steel and have scratched inside cone to be generated electron scatter and designed to be attached easily to the LINAC collimator and controlled cones length to be contacted smoothly between the patient and the cone tip. Two types of intracavitary cones were designed. One is the straight end cones with circular opening on the distal end and the other is 30 degree beveled end cones with elliptical opening on the distal end Each type of intracavitary cone ranged in daimeter from 2.5 cm to 3.5 cm and required a separate set of lower trimmer annulias cone diameter. The film phantom was designed with an internal cassette that accurately aligned the film edge with the film phantom surface. Film optical density data were measured by photodensitometer( Wellhofer 700i) Dosimetry measurements were made to commission the LINAC for 6 - 20 MeV electron using the intracavitary cones. Isodose curves were measured for all energy and cones combinations. Output is defined as the maximum dose per MU along the clinical central axis in water at 113 cm SSD. Calibration output, defined to be the output for the 15cm x 15cm diameter straight cone, was adjusted to 1.00 cGy/MU at each energy according to the TG-21 pro- tocol.

This study was attempted to investigate the level of knowledges on the use of radiations of some university students, that is to provide some useful information for designing education programs to improve the knowledge of the use of radia-tions. The survey was performed for 517 university students from Oct. 10 to Oct. 15, 2005. The results of this survey can be summarized as follows; students who didn't get educations for the use of radiations were recorded as 415 students (80.7%) in which the reason that they didn't get such educations was there were no chances to receive the education' as 265 students (77.9%). Regarding the survey on 'Energy productions using an atomic power plant can reduce electricity rates', the right answer was presented as the highest level (60.9%), the lowest rate of right answers was recorded in the survey on 'The average amount of atomic air raids of workers on the radiation related job pre-sented smaller levels than that of the average person'as 20.4%. The basic knowledge on the use of radiations was presented as a low level of 5.96 £ 2,90 points based on the sum of 15 points. There were significant differ-ences in these results statistically according to the age, sex, grade, majoring, score and experience of the education of radiations.
