CYPRUS is a web-based waste disposal research comprehensive information management program developed by the Korea Atomic Energy Research Institute over three years from 2004. This program is stored as existing quality assurance documents and data, and the research results can be viewed at any time. In addition, it helps to perform all series of tasks related to the safety evaluation study of the repository in accordance with the quality assurance system. In the future, it is necessary to improve the user convenience by clarifying the relationship between FEP and scenarios and upgrading output functions such as visualization and automatic report generation. This purpose of this study is to research and develop the advanced program of CYPRUS. This study is based on building FEP, DIM and scenario databases. It is necessary to develop an algorithm to analyze and visualize the FEP, DIM and scenario relationship. This project is an integrated information processing platform for DB management and visualization considering user convenience. The first development goal is to build long-term evolutionary FEP, DIM, and scenarios as a database. The linkage by FEP item was designed in consideration of convenience by using a mixed delimiter of letters and numbers. This design provides information on detailed interactions and impacts between FEP items. Scenario data lists a series of events and characteristic change information for performance evaluation in chronological order. In addition, it includes information on FEP occurrence and mutual nutrition by period, and information on whether or not the repository performance is satisfied by item. The second development goal is to realize the relationship analysis and visualization function of FEP and scenario based on network analysis technique. Based on DIM, this function analyzes and visualizes interactions between FEPs in the same way as PID, RES, etc. In addition, this function analyzes FEP and DIM using network analysis technique and visualizes it as a diagram. The developed platform will be used to construct and visualize the FEP DB covering research results in various disposal research fields, to analyze and visualize the relationship between core FEP and scenarios, and finally to construct scenarios and calculation cases that are the evaluation target of the comprehensive performance evaluation model. In addition, it is expected to support the knowledge exchange of experts based on the FEP and scenario integrated information processing platform, and to utilize the platform itself as a part of the knowledge transfer system for knowledge preservation.

Background: If the weakness of the knee muscles persists and there is pain at the same time, lumbar mobilization can be used. Objectives: This study investigated the immediate effect of lumbar joint mobilization on postural sway and knee pain in elite volleyball players. Design: Randomized controlled trial. Methods: Twelve male elite volleyball players were recruited for this study. Lumbar joint mobilization was performed in all study subjects. Evaluation items were static and dynamic balance and knee pain change. All evaluations were made immediately after the intervention. Results: C90 area, trace length, and STD Y deviation in the open static balance were significantly decreased after intervention (P<.05). C90 area, trace length, Velocity, STD X deviation, and STD Y deviation in static balance with closed eyes decreased significantly after intervention (P<.05). In dynamic balance, the left and right side. COPs were significantly increased. Pain significantly decreased after intervention (P<.05). Conclusion: This study found that lumbar joint mobilization is an effective method for improving postural sway and knee pain in elite volleyball players.

Background: Low back pain is a very common musculoskeletal disorder. Since low back pain can indicate physical and psychological problems, reducing the pain level of low back pain can be the primary goal of rehabilitation. Objectives: This study was performed to explain the personalized treatment protocol of Maitland orthopedic physiotherapy based on the brick wall concept for low back pain patients with hypomobility. Design: Randomized controlled study. Methods: A total of 14 chronic low back pain patients were divided into two groups. The experimental group received orthopedic manual physical therapy intervention. The control group received traditional physical therapy intervention. After the 3 days intervention, the joint range of motion and pain of the low back were measured. Results: The low back flexion, extension, lateral flexion, and rotation joint range of motion was significantly increased in the experimental group than in the control group (P<.05). Low back pain was significantly reduced in the experimental group than in the control group (P<.05). Conclusion: It was confirmed that Maitland orthopedic physical therapy was an effective method as an intervention method to improve the joint range of motion and pain of chronic low back pain patients.

Chlorine dioxide (ClO2) has recently emerged as an ideal disinfectant and has shown a wide range of antimicrobial activities in various pathogenic microorganisms. In this study, the virucidal effect of ClO2 at low concentration (0.02 ppm) and higher concentration (0.06 – 0.09 ppm) against Adenovirus and Herpesvirus was evaluated based on the NF T 72-281 and ASTM 1053-11 standard methods at different exposure times. The virus suspension was dried onto the carrier and then exposed to gaseous ClO2 (gClO2) at 22 ± 2∘C. For Adenovirus, exposure at a low concentration of ClO2 at the middle height resulted in the average log10 reduction of 0.95, 2.65, and 5.30 after 1, 3, and 6 h post-exposure (pe), respectively. Moreover, more than 4-log10 reduction was achieved at 4 and 6 h pe with higher concentrations of ClO2. On the other hand, the antiviral activity of gClO2 at the middle height was also effective against Herpesvirus. In particular, at 1 h pe, a less than 4-log10 reduction was observed at all examined concentrations of ClO2, whereas exposure for 3 and 6 h (with low concentration) or 2 h (with higher concentration) inactivated completely viruses attached to the carrier. These results suggested that ClO2 fumigation is a potential alternative method for disinfecting healthcare facilities, high-containment laboratories, and households with a safe concentration for human health.
