This study examined how the motivational language of instructors in senior fashion model classes affects learners' achievement goal orientation and interpersonal competence, as well as their intention to continue participating. The participants in this study were active seniors aged 50 and above, and the analysis was conducted using PLS-SEM and bootstrapping for mediation effects. It was found that autonomous motivation had a significant impact on task achievement goals and interpersonal competence, but not on ego achievement goals. On the other hand, controlled motivation only had a significant impact on ego achievement goals. Additionally, interpersonal competence had a significant impact on the intention to continue participating, and task achievement goals were found to mediate the relationship between autonomous motivation and interpersonal competence. This study aimed to promote understanding of the importance of instructors' motivational language in senior fashion model education and learners' psychology and to provide information that can help develop a fashion-related leisure activity curriculum. It also suggests efficient instructional directions for instructors in senior education, and it is expected to be utilized in the development of fashion-related leisure activity program curricula in the future.

For creative spatial design education, the convergence between new communication and education needs to be grafted including online, for which empirical research, this study is attempted. The goal of this study is to educate spatial design, systematically understand communication methods and analyze familiarity level and usefulness of on offline communication methods through actual spatial design studio class-giving cases. Its research outcome shows differing communication methods usefully applicable to stages of spatial design and methods enabling bilateral communication among class-takers as well as class-givers prove to be recognized as more useful than unilateral communication methods. Also, it proves familiarity and usefulness of online communication methods accompanied by visual materials such as images and etc. Based upon this result, it's necessary that various convergence for new communication methods for spatial design education be made in a right direction.

The current formal and memorized design repetition training and practice is wandering in the uniform flat design thinking expression. To change these two-dimensional current issues into a three-dimensional design method, set the direction for each grade level under the integrated convergence educational goal and carry out projects step by step to understand design, the principle of spatial composition, the introduction of traditional design history, and the overall design of craft design. Creative and practical skills such as approach should be cultivated. Designers can only be produced through systematic education and training. In order to lead society and succeed, a designer who has experienced solutions and countermeasures on how to adapt themselves to the demands of various changes in the times must come to the field. Education experts insisted on innovation of the organizational structure and subject of the education system, and emphasized the importance of education in response to the rapid pace of change in the 21st century. This study aims to propose an educational system that combines academic research with a structural approach to tasks by setting a project that reflects the needs of society for convergence practice in which design and adjacent disciplines are linked through understanding and analysis of these issues.

In recent society, great and small accidents have happened frequently, so the demands for safety have increased. As numerical increase of tourists who use the amusement facilities, many accidents owing to amusement facility has arisen. The goal of this study is that suggests the improvement plans for the safety management system of amusement facilities. In order to achieve the goal of study, legislations, industrial scale, accident situation, and others relating to amusement facility business were considered in a lot of ways. From a series of study results, improvement plans are suggested for safety inspection, accident compensation insurance, accident investigation, and others relating to amusement facility business.

The original RRT is iteratively expanded by applying control inputs that drive the system slightly toward randomly-selected states, as opposed to requiring point-to-point convergence, as in the probabilistic roadmap approach. It is generally known that the performance of RRTs can be improved depending on the selection of the metrics in choosing the nearest vertex and bias techniques in choosing random states. We designed a path planning algorithm based on the RRT method for a remote-controlled mobile robot. First, we considered a bias technique that is goal-biased Gaussian random distribution along the command directions. Secondly, we selected the metric based on a weighted Euclidean distance of random states and a weighted distance from the goal region. It can save the effort to explore the unnecessary regions and help the mobile robot to find a feasible trajectory as fast as possible. Finally, the constraints of the actuator should be considered to apply the algorithm to physical mobile robots, so we select control inputs distributed with commanded inputs and constrained by the maximum rate of input change instead of random inputs. Simulation results demonstrate that the proposed algorithm is significantly more efficient for planning than a basic RRT planner. It reduces the computational time needed to find a feasible trajectory and can be practically implemented in a remote-controlled mobile robot.

Recently, Industry 4.0 (next generation industrial revolution) designed by Germany to retain initiative in manufacturing business is actively studied. Goal of Industry 4.0 is 'Smart factory' which manages progress of production, supply logistics and services. To achieve the goal, we can construct value creation and new business model by integrating organically with production management systems which is existing and cyber-physical systems, Internet of Things, Services Internet and sensor, etc. However, if integration with production management systems does not work effectively by adding and developing new technologies, It does not have performance. Hence, in this research, we will analysis Industry 4.0 which is possible for small quantity batch production and one of the light and flexible manufacturing systems, and based on this, we will suggest methodology to horizontally integrate with production management systems.

The pursuit of independent self-development in adolescence and the development of self-identity are related to their adaptation in social life. In Korea, too, college is the place where graduates from high school go to advance in society. The purpose of study is to investigate the relationship between self - identity and college life in university students. First, self - identity has a positive effect on academic adjustment. Specifically, goal orientation has a positive effect on academic adjustment. Second, self - identity has a positive effect on emotional adjustment. In detail, self-acceptance, future confidence, and goal orientation were found to affect emotional adaptation. Finally, self - identity did not affect university satisfaction.

In this paper, we present a new multilevel in space and energy diffusion (MSED) method for solving multigroup diffusion eigenvalue problems. The MSED method can be described as a PI scheme with three additional features: (1) a grey (one-group) diffusion equation used to efficiently converge the fission source and eigenvalue, (2) a space-dependent Wielandt shift technique used to reduce the number of PIs required, and (3) a multigrid-in-space linear solver for the linear solves required by each PI step. In MSED, the convergence of the solution of the multigroup diffusion eigenvalue problem is accelerated by performing work on lower-order equations with only one group and/or coarser spatial grids. Results from several Fourier analyses and a one-dimensional test code are provided to verify the efficiency of the MSED method and to justify the incorporation of the grey diffusion equation and the multigrid linear solver. These results highlight the potential efficiency of the MSED method as a solver for multidimensional multigroup diffusion eigenvalue problems, and they serve as a proof of principle for future work. Our ultimate goal is to implement the MSED method as an efficient solver for the two-dimensional/three-dimensional coarse mesh finite difference diffusion system in the Michigan parallel characteristics transport code. The work in this paper represents a necessary step towards that goal.
