  • The field of design requires creative thinking in the era of the Fourth Industrial Revolution. Advanced educational process are needed to develop creative human resources. The ability to creatively develop or cope with new things is also seen as an important core competency. Therefore, this study develops a creative fashion design process and verifies its effect on core competencies in the era of the Fourth Industrial Revolution. For this, 29 college students majoring in fashion design were selected to form an experimental group, a comparative group, and a control group. A creative fashion design program was applied in the experimental group. However, the existing fashion design program was applied to the comparative group. The corresponding sample t-test was applied as an analysis method. The analysis results are as follows. In the experimental group, creative self-efficacy, self-efficacy for group work problem solving ability, and communicative ability improved. However, only communicative ability improved in the comparative group. There was no change in the control group. We proved the value of the study based on collected results. In addition, the results of this study can be used as a basic strategy for subsequent research.

  • KANT (KAIST Advanced Nuclear Tachygraphy) is a PWR core simulator recently developed at Korea Advance Institute of Science and Technology, which solves three-dimensional steady-state and transient multigroup neutron diffusion equations under Cartesian geometries alongside the incorporation of thermal-hydraulics feedback effect for multi-physics calculation. It utilizes the standard Nodal Expansion Method (NEM) accelerated with various Coarse Mesh Finite Difference (CMFD) methods for neutronics calculation. For thermal-hydraulics (TH) calculation, a single-phase flow model and a one-dimensional cylindrical fuel rod heat conduction model are employed. The time-dependent neutronics and TH calculations are numerically solved through an implicit Euler scheme, where a detailed coupling strategy is presented in this paper alongside a description of nodal equivalence, macroscopic depletion, and pin power reconstruction. For validation of the steady, transient, and depletion calculation with pin power reconstruction capacity of KANT, solutions for various benchmark problems are presented. The IAEA 3-D PWR and 4-group KOEBERG problems were considered for the steady-state reactor benchmark problem. For transient calculations, LMW (Lagenbuch, Maurer and Werner) LWR and NEACRP 3-D PWR benchmarks were solved, where the latter problem includes thermal-hydraulics feedback. For macroscopic depletion with pin power reconstruction, a small PWR problem modified with KAIST benchmark model was solved. For validation of the multi-physics analysis capability of KANT concerning large-sized PWRs, the BEAVRS Cycle1 benchmark has been considered. It was found that KANT solutions are accurate and consistent compared to other published works.

  • The purpose of the study was to define five science core competencies introduced in the 2015 revised science curriculum with each component and practical indicators into the frame. Science teachers on site could use it in teaching and developing science program to equip students with the competencies to creatively solve problems which is the aim of science education in the $21^{st}$ century. To develop this frame, we contacted 10 experienced science educators and collected the data through a questionnaire. We coded all responses and categorized into the components and practical indicators of each competency which were all compared with those from well-known theories in order to validate. We then contacted other 35 science educators again to construct the validity to fill out the survey of Likert scale. The finalized science core competency included 19 components in total with practical indicators that can be observable and measurable in the classroom. This frame was used to see how it fits into a STEAM program. The finding was that two different topics of the STEAM program displayed the different description of science core competency usage, which could be used as the prescription of the competency as to whether or not it is more promoted in science class.

  • The development of multicast communication services in the Internet is expected to lead a stable packet transfer even though On-Line Games generate heavy traffic. The Core Based Tree scheme among many multicast protocols is the most popular and suggested recently. However, CBT exhibits two major deficiencies traffic concentration or poor core placement problem. Thus, measuring the bottleneck link bandwidth along a path is important to understand the performance of multicast. We propose a method in which the core router's state is classified into SS(Steady State), NS(Normal State) and BS(Bottleneck State) according to the estimated link speed rate, and also the changeover of multicast routing scheme for traffic overload. In addition, we introduce Anycast routing tree, an efficient architecture for constructing shard multicast trees.

  • This paper presents the analysis results for the core degradation processes and the fission product release of the PHEBUS FPT0 experiment using MELCOR1.8.3. The objective of this study is to assess models associated with the core damage and fission product behavior in MELCOR. The calculation results were much improved through sensitivity studies. Thermal/hydraulic behavior in the core and the circuit was well predicted under the intact core geometry. In non-eutectic model case. the UO$_2$ dissolution model in the MELCOR always showed such a tendency that the resulting dissolved UO$_2$ mass was small at the highly oxidized condition due to the model logic. Total H$_2$ generation mass was underpredicted because the stiffner was not modeled and the liner in the shroud was not allowed to be oxidized in MELCOR. Some difficulties were found in modeling the activation product were solved by manipulating the RN input associated with the initial fission product inventory. These problem were occurred because there are no control rod model in MELCOR. Generally the fission product release ratio showed a similar trend compared with the measured data except the activation product. which have no model to simulate in MELCOR.

  • The aim of this study was to establish an university informal program roadmap, and also to draw up operational plans for human resources with core technologies of the fourth industry. To do this, first we derived university informal education program draft through experts workshop, then conducted a survey regarding the female university students' perception of educational programs and their educational needs on the 4th core technology matching programs. The following main results were obtained : First, students preferred 'hands-on training' by professionals and they wanted to be trained during summer or winter holidays or the night time during semesters. Also, they thought two hours of training per session was appropriate. Regarding these results, there was no difference depending on the majors. Second, while students had highly preferred for the courses related to data analysis, Arduino programing and VR(virtual reality), those related to 3D printing modeling were less preferred. Depending on the majors, preferred courses had different priorities, but non-preferred courses were similar regardless of majors. Based on these results, the university informal curriculum model and the operation plans for the core technologies of the fourth industry were proposed.
