  • The purpose of this study were to design and develop the user centered desk which considered children with cebral palsy in Korea. The developing process of the desk were performed the convergence study of the University Department of the Social Welfare and the Living Furniture Design. First of all, the 2 students and their professor of the Department of Social Welfare analyzed the literature, observed the children with cebral palsy and the needs survey of the service providers of a Welfare Center for children with cebral palsy. All of the information gathered were provided for the Department of the living Furniture Design. Second, the 2 students and their professor of the Department the Living Furniture Design proceeded the design concept, mocked up the desk for the children with cebral palsy. This was the user centered desk which considered of the features of children with cebral palsy body. Based on the results, the convergence study implications were discussed.

  • In this research the development of unstructured grid discretization solution techniques is presented. The purpose is to describe such a conservative discretization scheme applied for experimental validation work. The objective of this paper is to better establish the effects of mesh generation techniques on velocity fields and particle deposition patterns to determine the optimal aerodynamic characteristics. In order to achieve the objective, the mesh surface discretization approaches used the VLA prototype manufacturing tolerance zone of the outer surface. There were 3 schemes for this discretization study implementation. They are solver validation, grid convergence study and surface tolerance study. A solver validation work was implemented for the simple 2D and 3D model to get the optimum solver for the VLA model. A grid convergence study was also conducted with a different growth factor and cell spacing, the amount of mesh can be controlled. With several amount of mesh we can get the converged amount of mesh compared to experimental data. The density around surface model can be calculated by controlling the number of element in every important and sensitive surface area of the model. The solver validation work result provided the optimum solver to employ in the VLA model analysis calculation. The convergence study approach result indicated that the aerodynamic trend characteristic was captured smooth enough compared with the experimental data. During the surface tolerance scheme, it could catch the aerodynamics data of the experiment data. The discretization studies made the validation work more efficient way to achieve the purpose of this paper.

  • This study investigates numerical analysis for robot welder fume flow and gantry structure. The solvers are STAR-CCM+ and ANSYS workbench used on flow and structural analysis. The results show that fume is diffused in factory when the welding fume is remove at dust collector. But dust collector intercepts the fume diffusion into workroom by removing most of welding fume. Structure analysis result shows that the reinforcement rod is evaluated to main the safety by supporting sufficient structure.

  • The present study was performed to evaluate the antioxidant effect of crude extracts of Nelumbo nucifera Gaertner. Antioxidant effect was analysed by DPPH-radical scavenging activity, lipid peroxidation and superoxide dismutase (SOD)-like activity. DPPH-radical scavenging activity and SOD-like activity of linoleic acid, glutamic acid, ethyl acetate crude extract and ethyl alcohol crude extract of Nelumbo nucifera Gaertner were dose-dependently increased. However, lipid peroxidation of glutamic acid, linoleic acid, ethyl acetate crude extract and ethyl alcohol crude extract of Nelumbo nucifera Gaertner were time-dependently decreased. The data suggests that crude extracts of Nelumbo nucifera Gaertner may be a putative antioxidant substance and apply the development of medicine through convergence study.

  • Distraction osteogenesis is applied to correct mandible or maxilla deformities. Owing to the distractor being away from the skin, it is not aesthetic. Infection can arise due to manual part. And therefore, it is necessary to make the distractor using a new mechanism. 3D software was used for the intraoral distractor modeling. 3D meshes were used to analyze the stress distribution of the distractor was analyzed using Finite element analysis software. This research developed a intraoral distractor for continuous mandible distraction through convergence study. Base on the results, it provide helpful data for future version of the wireless intraoral distractor in other fields of bio and medical engineering.

  • The purpose of this study was to perform a convergence study for the investigation of the trend of research topics related to thyroid cancer in Korea. We collected related research papers from DBpia and employed LDA-based topic model. In result, we identified four research topics, each of which concerns "Surgery", "Disease aggressiveness", "Survival analysis", and "Well-being of patients". With multinomial logistic regression, we found significant time trend, where "Surgery"-related topic was popular before 2000, topics regarding "Disease aggressiveness" and "Survival analysis" were frequently addressed in the 2000s, and "Survival analysis" and especially "Well-being of patients" have been pursued since 2010. The findings would serve as a reference guide for research directions. Future work may examine whether the recent change in research topics is observed in other diseases.

  • This research was convergence study conducted to understand the effect that parent-son/daughter communications have on the addiction to smartphones, with stress level, self-control, and self-efficacy as the mediator. The subjects were college students located in J province and K province, and 232 questionnaires were used as the data for analysis. As a result, addiction to smartphones had negative correlations with parent-son/daughter communication, self-control, and self-efficacy and had positive correlations with stress level. In addition, parent-son/daughter communication influenced the degree of addiction to smartphones, with stress level, self-control, and self-efficacy as the mediator. Therefore, in order to reduce college students' addiction to smartphones, programs should be developed specifically and systematically to increase their communication with their parents, and it is necessary to draw up measures to reduce students' stress levels and increase their self-control and self-efficacy levels.

  • In order to identify the major stressors of some college students and their relationship with oral habits, a questionnaire survey was conducted for 299 male and female college students in Sunmoon University located in Asan-si, Chungcheongnam-do. As a result convergence study of analyzing stress by college students, the relationship between health and interpersonal relationship among the causes of stress was statistically significant. Based on the above studies, the incidence of oral habits caused by the stress of college students was very high. Considering that the stress factors that occur during college life cannot be completely excluded, it is necessary to have an education framework on improving stress self-recognition, control, and bad habits.
