The study was focused on setting priority for future core technologies in crops using Analytic Hierarchy Process (ARP). The technologies were derived by Delphi method. Evaluation criteria for the priority setting were decided as 'technology', 'market oriented', and 'public concerns' by council. The future core technologies were divided as four groups by importance and R&D level. Technologies in upper two groups were considered in the study. Group I had high importance and high R&D level. Group II had high importance and lower R&D level. Questionnaires were given to 8 specialists in crops. As the results, 'public concerns' was decided as the most important evaluation criterion. The most important technologies are 'developing of growing technology that has low inputs and production cost for environmental friendly agriculture' in group I, and 'developing of gene searching, characteristics transformation, and commercialization technologies for crops using bio-technology' in group II.

Recently, a wide variety of studies on future learning have appeared owing to rapid advances in information and communication technology (ICT) and increased discussion about core competencies in twenty-first-century learning. These studies, though insufficient in number, cover various fields such as architecture (design of the learning space), education (learning model), and technology (adaptation of mobile devices). However, these studies focus on mainstream students and do not discuss the future situation of inclusive education with regard to both mainstream and students with physical disabilities. Hence, in order to fill this gap, the present study explores the perceptions and ideas held by special education preservice teachers on the future learning space with regard to school design and peer-to-peer feedback. For this purpose, these preservice teachers' design proposals about future school were collected and analyzed. In conclusion, special education preservice teachers perceive the future learning space as an inclusive environment in which smart technology is incorporated. Future learning environment were categorized in terms of flexible, ubiquitous technology, physical and mental health, safety, and spaces with facilities for students with physical disabilities.

In this paper are reviewed the current status of nuclear fuel management and reactor operational aid tools. In addition, we indicate deficiencies in current capabilities and what future research is judged warranted. For the nuclear fuel management review the focus is on light water reactors and the utilization of stochastic optimization methods applied to the lattice, fuel bundle, core loading pattern, and for BWRs the control rod pattern/core flow design decision making problems. Significant progress in addressing separately each of these design problems on a single cycle basis is noted; however, the outstanding challenge of addressing the integrated design problem over multiple cycles under conditions of uncertainty remains to be addressed. For the reactor operational aid tools review the focus is on core simulators, used to both process core instrumentation signals and as an operator aid to predict future core behaviors under various operational strategies. After briefly reviewing the current status of capabilities, a more in depth review of adaptive core simulation capabilities, where core simulator input data are adjusted within their known uncertainties to improved agreement between prediction and measurement, is presented. This is done in support of the belief that further development of adaptive core simulation capabilities is required to further significantly advance the utility of core simulators in support of reactor operational aid tools.

This study provides the theoretical basis for the self-management of a sports center based on the core competence and technology of the future. The following conclusions were obtained. First, in the influence of self-management on the future core competencies, interpersonal management, training management, and physical management, the factors of self-management have a significant influence on cognitive, affective, and social factors of future core competence. Second, in the influence of self-management on the social skill scale, interpersonal management, training management, and physical management factors of self-management have a significant influence on the self-assertion, self-control, and cooperation of the social technology scale. Third, cognitive, affective, and social factors of the future core competence have a significant influence on the self-assertion, self-control, and cooperation of the social skill scale in the influence of the future core competence on the social skill scale. To improve the self-management and social skills of leaders by maintaining good relationships with the members including fellow instructors, it is essential to take appropriate measures for self-management behaviors considering the individual characteristics and environments of leaders; it appears that effort is important.

The point we made in this paper is that, although detailed and precise three-dimensional (3D) whole-core transport calculations may be obtained in the future with massively parallel computers, they would have an application to only some of the problems of the nuclear industry, more precisely those regarding multiphysics or for methodology validation or nuclear safety calculations. On the other hand, typical design reactor cycle calculations comprising many one-point core calculations can have very strict constraints in computing time and will not directly benefit from the advances in computations in large scale computers. Consequently, in this paper we review some of the deterministic 3D transport methods which in the very near future may have potential for industrial applications and, even with low-order approximations such as a low resolution in energy, might represent an advantage as compared with present industrial methodology, for which one of the main approximations is due to power reconstruction. These methods comprise the response-matrix method and methods based on the two-dimensional (2D) method of characteristics, such as the fusion method.

The purpose of this study was to extract the factors of core competency required for technology teachers and to analyze the educational needs for extracted core competency factors and to search for the application of core competencies in the in-service technology teachers education. This study was conducted by literature review, expert validation, and needs assessment method. The survey was conducted by 92 low-carrier technology teachers who participated in in-service technology teachers education for upgrading to first grade teacher certificate. Data were analyzed the factor analysis, needs assessment, and IPA analysis using SPSS 24. The core competencies with high education needs were selected by the score of the Borich formula and the IPA analysis. As a result of the study, 29 factors of core competencies were chosen as the priority: challenge, planning ability, decision making ability, future orientation, intellectual property utilization ability, communication ability, and creative thinking etc. Based on the conclusions of this study, I would suggest the following. It is to create a new in-service education program reflected on core competencies that have high educational needs of low-carrier technology teachers. In addition, a strategy that reflects core competencies methodically in existing in-service teachers education program is needed. Future research should be followed by research on curriculum design to enhance high needed core competencies of low-carrier technology teachers.

In this paper, the Window-Masking Method and HAT (Hardware Attached Top) CPU SoM (System on Module) are used to improve the performance and reduce the weight of the MANET (Mobile Ad-hoc Network) network synchronization system using time division redundancy. We propose converting it into a RISC-V based soft-core MCU and mounting it on an FPGA, a hardware accelerator. It was also verified through experiment. In terms of performance, by applying the proposed technique, the synchronization acquisition range is from -50dBm to +10dBm to -60dBm to +10dBm, the lowest input level for synchronization is increased by 20% from -50dBm to -60dBm, and the detection delay (Latency) is 220ns. Reduced by 43% to 125ns. In terms of weight reduction, computing resources (48%), size (33%), and weight (27%) were reduced by an average of 36% by replacing with soft-core MCU.
