This study is an experimental study to examine the effect of the 1:1 coaching and example ideas with the GROW model on the creativity of new product ideas. Participants were composed of 32 adults who did not know coaching and were not related to new product development-related industries, and the experiment was randomly assigned to 1:1 coaching group, example idea group, and control group. The ideas answered by the participants were evaluated by measuring novelty, appropriateness, and willingness to pay after the experiment, and 30 experimental data and 3 expert group evaluation data were used for the final analysis. As a result of the study, the 1:1 coaching using the GROW model had a significant effect on the creativity of new product ideas, and in particular, had a positive effect on novelty. The example idea group received the lowest score among the three groups, including the control group, in novelty and suitability, and was found to have a negative effect on idea creativity. Based on these results, implications and limitations for the use of coaching in the work or situation of presenting creative ideas were discussed, and suggestions for follow-up studies were made.

Apps and games continue to grow in size as new content comes and compete on Google Play. As apps and games grow in size, app installs through the Google Play store are decreasing. The article talks about the structure and limitations of the existing support model, APK, and discusses the new support model, the Android App Bundle (AAB) structure. We will also look into future prospects.

The purpose of this study is to develop a personality education program that can enhance the virtues of elementary school students, self-esteem, Consideration communication, self-control, honesty courage by using coaching methodologically, To improve the personality virtue. The subjects of this study were 31 students from 4th grade of U elementary school in S Gu, Seoul. The experimental group was divided into 16 sessions, weekly from March 5, 2018 to June 30, 2018, 1 hour (40 minutes). The program consisted of items such as self-esteem, Consideration communication, self-control, honesty courage among the personality virtues of KEDI personality test, Each activity used a tough coaching model developed by combining the GROW model with the Empowering model and considering the developmental level of elementary school students. As a result, all four virtues of personality were significantly improved, model with the Empowering model and considering the developmental level of elementary school students. We compared pre and post test result with paired t-test. As a results, the experimental group showed improvement in all four virtues of personality at 0.05 significance level, whereas the control group did not. This suggests that the program can be usefully used as a tool to improve four virtues of personality of elementary school students. For further research, we expect that the program would be integrated with state-of-art technology such as online program or CBI(Computer-Based Instruction).

As today's network infrastructure continues to grow and DiffServ IP networks ate now available to provide various levels of flexible QoS services. DiffServ guarantees good scalability but shows dynamic QoS dependent on network traffic loads. Therefore, in this paper, we investigate the dynamics of DiffSev QoS and present analytical model to estimate the allowable traffic load under the given network conditions.

Convergence services are very important to mobile operators in next generation mobile networks. However, mobile operators cannot deal with all convergence services because there are numerous convergence services. Thus, they should select and develop main technologies to provide convergence services which are areas to grow our business. In this paper, we introduce basic technologies to provide convergence services and then present some evaluation models to select an important area and technology.

In recent years, Computer-based learning, such as machine learning and deep learning in the computer field, is attracting attention. They start learning from the lowest level and propagate the result to the highest level to calculate the final result. Research literature has shown that systematic learning and growth can yield good results. However, systematic models based on systematic models are hard to find, compared to various and extensive research attempts. To this end, this paper proposes the first TNT(Transitive Nested Triangle)model, which is a growth and fusion model that can be used in various aspects. This model can be said to be a recursive model in which each function formed through geometric forms an organic hierarchical relationship, and the result is used again as they grow and converge to the top. That is, it is an analytical method called 'Horizontal Sibling Merges and Upward Convergence'. This model is applicable to various aspects. In this study, we focus on explaining the TNT model.

It is generally required to use modeling or animation tools for inserting dynamic objects into augmented reality, and this process demands high expertise and complexity. This paper proposes a video object based authoring method that enables augmentation with dynamic video objects without such process. Integrated grab-cut and grow-cut method strips initial area of video target off the existing video clips, and snap-cut method is then applied to track objects' boundaries over frames so as to augment real world with continuous motion frames. Experiment shows video cut-out and authoring results achieved by only a few menu selections and simple correcting sketch.

There is a growing interest in plant factories around the world, and in recent years, research on an automated management system that can grow crops even in an urban environment is in progress. The development of this management system is based on the development of ICT (Information Communications Technology) technology, and research is being conducted focusing on facilities, light sources, temperature, humidity and automation to increase the productivity of plants. Research on standardization is ongoing. In this paper, by constructing a test bed that can grow hydroponic ginseng in a container environment, we propose a model that can monitor and manage the environment for the growth process on mobile.

In this study a model for the constitutive relation of a plane concrete is proposed using a micromechariical model. In this model a precursor crack is assumed to exist in the aggregate-cement paste interface, and the LEFM is used to predict the nucleation of the bond cracks and the grow th of mortar cracks. For computational convenience the bond crack-mortar crack configuration is transformed into a straight crack with a point force in the middle. 'The overall compliance and the cons,titutive relation are predicted from the damage due to microcracks, and the predicted stress-strain curves are compared with some experimental data. According to the results, the model predictions are better for under tensile loading than under compression, for high, strength concrete than for normal strength concrete.

Cavitation is described by formation and collapse of the bubbles in a liquid when the ambient pressure decreases. Formed bubbles grow and collapse by change of pressure, and when they collapse, shockwave by high pressure is generated. In general, bubble behavior can be described by Rayleigh-Plesset equation under adiabatic or isothermal condition and hence, phase shift by the pressure change in a bubble cannot be considered in the equation. In our study, a numerical model is developed from the mathematical model considering the phase shift from the previous study. In the developed numerical model, size of single spherical bubble is calculated by the change of mass calculated from the change of the ambient pressure in a liquid. The developed numerical model is verified by a case of liquid flow in a narrow channel.
