In this study, using PC server. we developed large scale hospital order communication system which is classified into 3 categories of business: clinical business, clinical support business, patient management business. In all the programs to build OCS, the user's convenience was considered as a top priority. which was built in the environment of 'window'; in this, the tool to develop the programs was a 'Visual Basic' In consideration of the aspect of operation. the programs were consolidated into one kind. The database was built into a relation-type database. MS/SQL which is easily interchangeable or portable personal database: and data exchange with real users was also made casy. Since all kinds of business concerned built in open system, this hospital information system can actively cope with any of environmental changes, and since this system was developed by manpower within an organization of a hospital. the system can flexibly and efficiently correspond to its operation.

OBJECTIVE: We investigated the effect of optimization in dose-limiting shell method on the dosimetric quality of CyberKnife (CK) plans in treating brain metastases (BMs).METHODS: We selected 19 BMs previously treated using CK between 2014 and 2015. The original CK plans (CKoriginal) had been produced using 1 to 3 dose-limiting shells : one at the prescription isodose level (PIDL) for dose conformity and the others at lowisodose levels (10–30% of prescription dose) for dose spillage. In each case, a modified CK plan (CKmodified) was generated using 5 dose-limiting shells : one at the PIDL, another at intermediate isodose level (50% of prescription dose) for steeper dose fall-off, and the others at low-isodose levels, with an optimized shell-dilation size based on our experience. A Gamma Knife (GK) plan was also produced using the original contour set. Thus, three data sets of dosimetric parameters were generated and compared.RESULTS: There were no differences in the conformity indices among the CKoriginal, CKmodified, and GK plans (mean 1.22, 1.18, and 1.24, respectively; p=0.079) and tumor coverage (mean 99.5%, 99.5%, and 99.4%, respectively; p=0.177), whereas the CKmodified plans produced significantly smaller normal tissue volumes receiving 50% of prescription dose than those produced by the CKoriginal plans (p < 0.001), with no statistical differences in those volumes compared with GK plans (p=0.345).CONCLUSION: These results indicate that significantly steeper dose fall-off is able to be achieved in the CK system by optimizing the shell function while maintaining high conformity of dose to tumor.

Purpose: This study aimed to evaluate the utilization and outcomes of resuscitative endovascular balloon occlusion of the aorta (REBOA) in managing noncompressible torso hemorrhage (NCTH) among trauma patients in Korea. The evolution of REBOA and its impact on patient survival was investigated as well as predictors of mortality. Methods: This retrospective study included 234 post-REBOA patients from 5 leading regional trauma centers across Korea between 2016 and 2021. Primary outcomes were in-hospital mortality, and secondary outcomes were various clinical parameters regarding REBOA, overall treatment flow, and complications. For comparative analyses, patients were dichotomized into in-hospital non-survivors or survivors. Then, generalized additive and linear regression models were used to evaluate the trend of in-hospital mortality. Results: The overall in-hospital mortality was 65.4%. The survivors had a higher proportion of responders following REBOA (87.7% vs 62.7%, p < 0.001). Key variables influencing outcomes included total occlusion time, red blood cell transfusion volume within the first 24 hours, revised trauma score, and systolic blood pressure gap. These factors significantly correlated with mortality rates in multivariate logistic regression. Conclusion Over 6 years, survival rates for NCTH patients undergoing REBOA in Korea have shown improvement. Despite diverse REBOA protocols across institutions, the results underscore the need for continued research, standardized practices, and national quality control measures to further optimize patient outcome and establish more effective treatment protocols for NCTH.
