Abstract Understanding the behavior of scattered radiation is important for learning appropriate radiation protection methods, but many existing visualization systems for radiation require special devices, making it difficult to use them in education. The purpose of this study was to develop teaching material for radiation protection that can help visualize the scattered radiation with augmented and virtual reality on a web browser, develop a method for using it in education and examine its effectiveness. The distribution of radiation during radiography was calculated using Monte Carlo simulation, and teaching material was created. The material was used in a class for department of radiological technology students and its influence on motivation was evaluated using a questionnaire based on the evaluation model for teaching materials. In addition, text mining was used to evaluate impressions objectively. Educational material was developed that can be used in augmented and virtual reality for studying the behavior of scattered radiation. The results of the questionnaire showed that the average value of each item was more than 4 on a 5-point scale, indicating that the teaching material attracted the interest of users. Through text mining, it could be concluded that there was improved understanding of, and confidence in, radiation protection.

Abstract As chest x rays involve risks of patients falling, radiologic technologists (technologists) commonly assist patients, and as the assistance takes place near the patients, the eye lenses of the technologists are exposed to radiation. The recommendations of the International Commission on Radiological Protection suggest that the risk of developing cataracts due to lens exposure is high, and this makes it necessary to reduce and minimize the exposure. The present study investigated the positions of technologists assisting patients that will minimize exposure of the eye lens to radiation. The results showed that it is possible to reduce the exposure by assisting from the following positions: 50% at the sides rather than diagonally behind, 10% at the right side of the patient rather than the left and 40% at 250 mm away from the patient. The maximum reduction with radiation protection glasses was 54% with 0.07 mmPb and 72% with 0.88 mmPb.

HighlightsRegulated deficit irrigation and fertilization ratio were used to test grapes in extremely arid areas.Physiology, yield, and quality indexes of drip irrigation grapes were analyzed accordingly in this study.Single and comprehensive evaluation models were used to evaluate the optimal water and fertilizer treatment.Abstract. Water shortage and chemical fertilizer abuse are important factors restricting grape industry development in Xinjiang. In this study, the physiology, yield and quality indexes of drip irrigation grapes were analyzed, and the water-fertilizer system was properly optimized by a model of combination of single evaluation methods and comprehensive evaluation methods. Five irrigation schemes and three fertilizer ratios were combined to form 15 treatments in Xinjiang, China. Results showed that irrigation and fertilization had different effects on physiology, yield, and quality indicators of grapes in different growth periods, and each index cannot reach its maximum value under the same treatment. Four single evaluation methods of Principal Component Analysis (PCA), Membership Function Analysis (MFA), Gray Correlation Analysis (GCA), and TOPSIS were used to evaluate grapes of 15 water and fertilizer treatments, but there were 9 treatments with a ranking standard deviation greater than 1.0, which was over 60% of all treatments. Through four comprehensive evaluation methods of Average Value, Borda, Copeland, and Fuzzy Borda, single evaluation results were analyzed, and the standard deviations of 13 treatments ranked 1.0 or below, more than 80% of all treatments, and Average Value comprehensive method had the highest compatibility. Therefore, the combination of Average Value method and four single evaluation methods is an appropriate evaluation model. It was determined that W4F2 was the optimal treatment which was performed regulated deficit irrigation in the berry mature period, the irrigation amount, nitrogen, phosphorus, and potassium fertilizers were sequentially controlled to 694 mm, 235.7, 235.7, and 353.6 kg·ha-1, and its ranking was ranked first under the four comprehensive evaluation methods. This study can provide theoretical guidance for the combined evaluation of water and fertilizer use of drip irrigation grapes in extremely arid regions.

In the last two decades the definition of the term “virtual museum” changed due to rapid technological developments. Using today’s available 3D technologies a virtual museum is no longer just a presentation of collections on the Internet or a virtual tour of an exhibition using panoramic photography. On one hand, a virtual museum should enhance a museum visitor's experience by providing access to additional materials for review and knowledge deepening either before or after the real visit. On the other hand, a virtual museum should also be used as teaching material in the context of museum education. The laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has developed a virtual museum (VM) of the museum “Alt-Segeberger Bürgerhaus”, a historic town house. The VM offers two options for visitors wishing to explore the museum without travelling to the city of Bad Segeberg, Schleswig-Holstein, Germany. Option a, an interactive computer-based, tour for visitors to explore the exhibition and to collect information of interest or option b, to immerse into virtual reality in 3D with the HTC Vive Virtual Reality System.

The paper reviews the efficience of radiation protection in uranium mining industry. The officially provided data on individual doses for underground and surface mining professionals is analysed and cancer morbity risk is assessed. The researchers defined the individual components of the total effective dose and separately assessed their contributions. The total of 114 cancer cases have been registered during the past 15 years. Accumulated equivalent doses for lungs are estimated from 20 to 430 mSv. The total working time in 56% of individual cancer cases diagnosed made over 20 years. The actual lung cancer mortality rate for miners is established 3 cases per 1000 individuals, which permits to question the authenticity of the dosimetric data and the efficiency of radiological protection applied.

This study aims to evaluate the implementation and understanding of the training participants regarding the knowledge of the training materials provided at the Advanced Infection and Prevention Technical Training for Health Workers at the Health Facilities during the COVID-19 Pandemic online, which was held at the Puslatkesda Provinsi DKI Jakarta. This study uses a quantitative description method using the Kirkpatrick Four Levels Evaluation Model, namely through four levels consisting of reaction, learning, behavior, and result. As for what was carried out in the study, it was evaluated at levels 1 and 2. This training was held in October 2020 Batch 1 with 40 participants. Instruments The instrument used is a questionnaire, and the results of the participants' assessment are in the form of pretest and posttestt. The source of data in this study is Puslatkesda data in 2020, namely primary data on the implementation of Advanced PPI Technical Training during the COVID-19 Pandemic. Following are the results of the research data analysis that of the seven evaluation categories at the reaction level to the implementation of the training. The results showed that as many as 18 respondents with a percentage of (45 percent) answered Very Satisfactory, then for reactions to resource persons an average, of 52.5-82.5 percent participants answered satisfactorily and very satisfactory. As for the evaluation of learning or learning, it appears that the average value of participants is 84.3, and there are 100 percent (40) training participants who have complete scores in the posttest stage. With all these descriptions, the Advanced Infection and Prevention Technical Training for Health Workers at Health Facilities during the COVID-19 Pandemic went well and satisfactorily.
