Structured Reporting of Computed Tomography and Magnetic Resonance in the Staging of Pancreatic Adenocarcinoma: A Delphi Consensus Proposal

Background: Structured reporting (SR) in radiology has been recognized recently by major scientific societies. This study aims to build structured computed tomography (CT) and magnetic resonance (MR)-based reports in pancreatic adenocarcinoma during the staging phase in order to improve communication between the radiologist and members of multidisciplinary teams. Materials and Methods: A panel of expert radiologists, members of the Italian Society of Medical and Interventional Radiology, was established. A modified Delphi process was used to develop the CT-SR and MRI-SR, assessing a level of agreement for all report sections. Cronbach’s alpha (Cα) correlation coefficient was used to assess internal consistency for each section and to measure quality analysis according to the average inter-item correlation. Results: The final CT-SR version was built by including n = 16 items in the “Patient Clinical Data” section, n = 11 items in the “Clinical Evaluation” section, n = 7 items in the “Imaging Protocol” section, and n = 18 items in the “Report” section. Overall, 52 items were included in the final version of the CT-SR. The final MRI-SR version was built by including n = 16 items in the “Patient Clinical Data” section, n = 11 items in the “Clinical Evaluation” section, n = 8 items in the “Imaging Protocol” section, and n = 14 items in the “Report” section. Overall, 49 items were included in the final version of the MRI-SR. In the first round for CT-SR, all sections received more than a good rating. The overall mean score of the experts was 4.85. The Cα correlation coefficient was 0.85. In the second round, the overall mean score of the experts was 4.87, and the Cα correlation coefficient was 0.94. In the first round, for MRI-SR, all sections received more than a good rating. The overall mean score of the experts was 4.73. The Cα correlation coefficient was 0.82. In the second round, the overall mean score of the experts was 4.91, and the Cα correlation coefficient was 0.93. Conclusions: The CT-SR and MRI-SR are based on a multi-round consensus-building Delphi exercise derived from the multidisciplinary agreement of expert radiologists in order to obtain more appropriate communication tools for referring physicians.

COVID-19: Business Innovation Challenges

The goal of this paper was to investigate how the COVID-19 pandemic has affected the readiness and ability to innovate in business. The paper’s objective and research questions were pursued with a traditional literature review and an original diagnostic survey using an original questionnaire with a respondent data section and close-ended questions. Responses were collected using the CAWI technique. The primary conclusion was that businesses disturbed by the COVID-19 pandemic were more able to innovate in terms of products and management than those that remained unaffected. Regarding theoretical implications, the author proposed a business model for enterprises operating in the COVID-19 environment. The implications of the model are the practical results of the research.

LEVEL OF FAILURE RISK BASED ON LAND TYPOLOGY OF PARTICIPANTS OF RICE FARM INSURANCE PROGRAMS IN SOUTH SUMATERA

Risk level in South Sumatra differs based on the land typology in which Buay Madang Timur District in East OKU Regency with typical irrigation rice field typology has different risk level compared to Banyuasin Regency with its tidal land typology. This research was aimed to find out risk failure in two land typologies nad losses due to its risk. The calculation of Z score was used to calculate risk level using cross data section in year 2019. Data were collected from each district with 120 AUTP farmer participants consisted of 60 samples of tidal land typology and 60 technical irrigation. Which 60 samples consisted of 52 unclaimed farmers and 8 claimed farmers. Based Z score calculation of crop failure risk, it was resulted that technical irrigation land typology in OKU Regency had 44% risk level due to rat and planthopper attack, compared to 49% tidal land typology in Banyuasin Regency that caused rat attack. Risk impact due to crop failure was then calculated using the Value at Risk (Var) method. Results showed that crop failure losses in East OKU Regency were equal to Rp. 11.304.361,- for each planting season while in Banyuasin Regency it was Rp. 12.445.273,-. Thus, the impact of crop failure risk in tidal land typology was greater than technical irrigation.

Analysis of cross sections on iron and oxygen using Cf-252 neutron source

The leakage neutron spectra measurements have been done on benchmark spherical assemblies with Cf-252 source in center of 1) heavy water sphere with diameter of 30 cm (with Cd cover) and of 2) iron spheres with diameter of 100 cm and 50 cm. It has been stated for years that transport calculations by iron overestimate measured spectra in energy region around 300 keV by about 20-40 % (calculation to measurement ratio C/E = 1.2-1.4). The influence of an artificial changes in cross-section XS-Fe-56 (n,elastic)designed by IAEA, Nuclear Data Section, has been studied on the iron spheres. Influence of those XS-corrections to calculated neutron spectrum is presented.
