Background: Outcome measures (OMs) are essential components of evidence- based practice as they help in implementing interventions and assessing changes in a patient's status before and after treatment. However, many therapists do not utilize OMs in their practice, and research on the factors that influence physical therapists' decisions regarding the use of OMs primarily consists of quantitative or survey-based studies. Objectives: The purpose of this study was to select research studies on OMs use among physical therapists through a systematic review, identify questionnaire characteristics, and assess the quality of items collection and research. Design: A systematic review. Methods: This study systematically collected survey studies on the use of OMs from five databases (KMBase, RISS, KCI, Pubmed, and Cochrane) based on the criteria of PRISMA's systematic review flowchart. The quality of the studies was assessed using the AXIS Tool. Results: A total of eight studies were selected. In most of the studies, the questionnaires were developed internally, validated through preliminary research, and reliability testing was not conducted. The items used within OMs were divided into 10 categories, with the highest frequency of questions centering around how to use OMs, and the lowest frequency regarding work environment and reasons. All eight studies were determined to be of good quality. Conclusion: The collected OMs questionnaires revealed variations in the item frequency. Future qualitative research and participant feedback are needed to develop a consistent questionnaire and validate its validity and reliability.

Background: Some patients may not fully recover their daily activity capabilities even after the total hip replacement (THR), and may continue to experience functional limitations for up to a year after the procedure, according to reports. Objectives: The purpose of this study was to examine the effects of machine squat on muscle strength, balance and gait in patients after THR. Design: A randomized controlled trial. Methods: Thirty-three patients after THR were randomly allocated into slide (n=11), reformer (n=11), and control groups (n=11). Each group underwent their respective squat regimens for thirty minutes, seven times a week, for two weeks. Muscle strength changes were assessed using the manual muscle test (MMT), balance was evaluated using the Berg Balance Scale (BBS), and gait analysis was performed using the 10-meter walk test (10MWT). Results: Significant changes in hip flexor and abductor strength were observed in the slide and reformer groups within each group (P<.05). The reformer group showed significant changes in hip extensor strength (P<.05). Significant improvements in BBS were observed in all three groups (P<.05). There were significant changes in 10MWT in the slide and reformer groups (P<.05). A significant difference in hip extensor strength was found between the reformer and control groups after the intervention (P<.0167). Significant differences in BBS were observed between the slide and reformer groups and between the reformer and control groups after the intervention (P<.0167). Conclusion: Our findings suggest that machine squat regimens can be effective for early rehabilitation after THR, improving muscle strength, balance, and gait.

Background: Junior colleges have been establishing plans for the development of start-up education for students and have been providing various educational programs to support students’ start-up businesses. Objectives: The effects of entrepreneurship and entrepreneurial self-efficacy on the start-up intention of college physical therapy students were analyzed. Design: Questionnaire design. Methods: Surveys on entrepreneurship, entrepreneurial self-efficacy, and start-up intention were conducted with 269 college physical therapy students, and the levels of individual measurement variables, correlations, and variables affecting start-up intention were analyzed. Results: College physical therapy students showed differences in start-up intention between genders, and male students tended to have a higher startup intention (P<.001) than female students. The correlations among the major variables were analyzed. According to the results, all sub-factors of start-up intention had significant positive correlations with all sub-factors of entrepreneurship and entrepreneurial self-efficacy (P<.05). In addition, multiple regression analysis was conducted to identify factors affecting start-up intention. Start-up education was shown to have no direct effect on start-up intention. Innovation (β=.238, P=.000), risk sensitivity (β=.228, P=.000), and initiative (β=.220, P=.001), which are sub-factors of entrepreneurship, were shown to have effects on start-up intention. Self-regulated efficacy (β=-.193, P=.039) and task challenge (β=.210, P=.004), which are sub-factors of entrepreneurial self-efficacy, were found to have effects on start-up intention. Conclusions: To boost the start-up intention of college physical therapy students and induce their start-ups, customized start-up education that considers entrepreneurship level and gender is necessary.

The Radiation and Decommissioning Laboratory of Central Research Institute (CRI) of Korea Hydro and Nuclear Power Co. (KHNP) performs research to technically support the effective management of radiological hazards to avoid risks to civilians, the workers, and the environment from the radiological risks. The laboratory mainly consists of three technical groups: decommissioning and SF technology group, radiation and chemistry group, and radwaste and environment group. The groups carry out various R&D such as decommissioning, spent fuel management, radiation protection, water chemistry management, and radioactive waste management. The laboratory also technically supports the calibration of radiometric instruments as a Korea Laboratory Accreditation Scheme (KOLAS), approval for decommissioning, guidance for radioactive waste management, state-of-the-art technology evaluations, and technology transfer.

This study investigated the growth behavior and characteristics of compounds formed at the interface between a liquid Al-Si-Cu alloy and solid cast iron. Through microstructural analyses, it was observed that various AlFe and AlFeSi phases are formed at the interface, and the relative proportion of each phase changes when small amounts of strontium are added to the Al alloy. The results of the microstructural analysis indicate that the primary phases of the interfacial compounds in the Al-Si-Cu base alloy are Al8Fe2Si and Al4.5FeSi. However, in the Sr-added alloys, significant amounts of binary AlFe intermetallic compounds such as Al5Fe2 and Al13Fe4 formed, in addition to the AlFeSi phases. The inclusion of Sr has a slight diminishing effect on the rate at which the interfacial compounds layer thickens during the time the liquid Al alloy is in contact with the cast iron. The study also discusses the nano-indentation hardness and micro-hardness of the interfacial phases.

United States Nuclear Regulatory Commission (U.S. NRC) specifies regulations on obtaining licenses and describes the technical position on the average waste concentration, also known as Concentration Averaging and Encapsulation Branch Technical Position (CA BTP); CA BTP helps classify blendable waste and discrete items and address concentration averaging. The technical position details are reviewed and compared in a real environment in Korea. A few cases of concentration averaging based on the application of CA BTP to domestic radioactive waste are presented, and the feasibility of the application is assessed. The radioactive waste considered herein does not satisfy the Disposal Concentration Limit (DCL) of the second-phase disposal facility while applying the preliminary classification. However, if CA BTP is applied when the radioactive waste is mixed with other radioactive waste items in a large and heavy container, it can be disposed of at the second-phase disposal facility in Gyeongju Repository. To apply the CA BTP of the U.S. NRC, it is necessary to investigate the safety assessment conditions of the US and Korea.

Silene fissipetala Turcz., which is native to Continental China and Taiwan, was newly found in Chungcheongnam-do, Korea. S. fissipetala is similar to the related taxa S. antirrhina L., S. armeria L., and S. koreana Kom. in that it has glutinous zones. However, S. fissipetala is distinguished from the congeneric species by the presence of laciniate at the petals. The species grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, photographs, voucher specimens and a key to related taxa are provided.

At a time when the demand for drones is increasing, a plan to utilize drone images was sought for efficient promotion of cadastral resurvey. To achieve the purpose of this study, the technical and legal status of drone images was reviewed, and through this, the possibility of using it for cadastral resurvey was primarily reviewed. subsequently, an experiment was conducted targeting the project district to examine whether drone images were applied to boundary extraction, which is the primary process of cadastral resurvey. As a result of the experiment, it was found that boundary extraction from images is possible. However, in some cases, it is impossible due to field conditions or image quality. Therefore, it is necessary first to apply cases where boundary extraction is possible to cadastral resurvey and seek solutions for some impossible cases. In particular, the image quality problem may have problems with the current technology, but it will also have problems with the existing drone equipment. So, standard for drone calibration should also be established. Finally, the cadastral resurvey surveying procedure using drones was also presented.

Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

This study was conducted to calculate the damage of Italian ryegrass (IRG) by abnormal climate using machine learning and present the damage through the map. The IRG data collected 1,384. The climate data was collected from the Korea Meteorological Administration Meteorological data open portal.The machine learning model called xDeepFM was used to detect IRG damage. The damage was calculated using climate data from the Automated Synoptic Observing System (95 sites) by machine learning. The calculation of damage was the difference between the Dry matter yield (DMY)normal and DMYabnormal. The normal climate was set as the 40-year of climate data according to the year of IRG data (1986~2020). The level of abnormal climate was set as a multiple of the standard deviation applying the World Meteorological Organization (WMO) standard. The DMYnormal was ranged from 5,678 to 15,188 kg/ha. The damage of IRG differed according to region and level of abnormal climate with abnormal temperature, precipitation, and wind speed from -1,380 to 1,176, -3 to 2,465, and -830 to 962 kg/ha, respectively. The maximum damage was 1,176 kg/ha when the abnormal temperature was -2 level (+1.04℃), 2,465 kg/ha when the abnormal precipitation was all level and 962 kg/ha when the abnormal wind speed was -2 level (+1.60 ㎧). The damage calculated through the WMO method was presented as an map using QGIS. There was some blank area because there was no climate data. In order to calculate the damage of blank area, it would be possible to use the automatic weather system (AWS), which provides data from more sites than the automated synoptic observing system (ASOS).

In this study, an experiment was conducted on the domestic cultivar 'White and Cool' on a farm in Taean to compare the effects of conventional soil cultivation and net cultivation to increase yield and reduce labor input time during outdoor gladiolus cultivation. The above- and below-ground growth, yield, and input labor time were investigated after cultivating half of the seedlings using the conventional cultivation method and the other half using the net cultivation method. There was no difference in the above- or below-ground growth between net cultivation and conventional cultivation. However, the labor input time decreased 2.57 times, the yield of the irrigated area increased by 3%, and the self-fertilization yield increased by 28%. Based on these results, several factors should be considered during net cultivation. First, loose netting should be used for root development. Second, care should be taken while flattening when planting seedlings, and after sowing, the area should be covered with a net to prevent drying. Third, after completion of the installation, compaction should be performed to ensure close contact between the soil and netting, and after removing the space between the nets, the seedlings should be irrigated to induce early rooting.
