The purpose of this study is to investigate the transformation of affordance in iOS GUI design and the relationship of affordances. We figured out variety kinds of Affordance concepts and choosed six Affordances(Visceral, Behavioral, Reflective, Explicit, Metaphorical, Pattern Affordance) Based on the previous studies. The result of investigating the transformation of iOS GUI design which based on the viewpoint of these 6 Affordance we have chosen is as follows. Firstly, the Visceral Affordance of iOS GUI design has already sufficiently become to the Reflective Affordance. So we can ignore or ellipsis the Visceral Affordance and the addition of specific Explicit Affordance can be possible. Secondly, due to the use experience of iOS, Behavioral Affordance and Pattern Affordance have already become to a kind of Reflective Affordance. Through this evolution, new kind of Pattern Affordance is formed. At the mean time, it also applied the basic field of Metaphorical Affordance. Thirdly, investigating the Flat Design of iOS based on the viewpoint of Affordance, we have figured out that Visceral Affordance has been reduced. So that the constrains of visual performance has also been reduced. This is the reason that there are more space remained in screen layout design, the color has become more natural and more Explicit Affordance has been provided, ect. Futhermore, in this thesis we have also figured out that there are some interactions and relationships between each Affordance. With the development of iOS, some Affordances have transformed to other Affordances. With the accumulation of use experience, Visceral Affordance has transformed to Reflective Affordance based on the field of Metaphorical Affordance. With the disappearance or reduction of Visceral Affordance, iOS provide Explicit Affordance instead. As a result of this kind of process, a new Pattern Affordance has been formed.

With technological development of product designs, products of various concepts have been developed and products by customized design concepts have been actively launched. For successful development, it is necessary to convey the target concept to the product development process exactly in order to create the targeting design. The study found the design concept of mobile phones with a boom box through emotional verbal expression, and defined the concept target by using visual images in accordance with the relative target with a view to looking for the design concept suitable to product development target. Regarding the visual image, the test for coordination among participants was conducted to select the image on which the interest groups participating in the development reach an agreement. As a result of the test, it aimed to propose the method to select concepts and images for rational choice by means of clustering algorithms. This method is considered to contribute to building the design concept and actualizing GUI design.

The touch screen phone launched domestically in Korea, unlike the existing plane UI, it applied a cubic shape of 3D UI which provides three dimensional solid graphic. This study proposes to examine the correlation between the users' experience of 3D GUI, which were made by two different companies, and the brand. From this point of view, this study sets up a hypothesis about intimate correlation between individual differentiated brand and the user experience. Base on that, a model was designed. This study measured the satisfaction of user experience through the disclosure and non-disclosure of brand, focusing on 3D GUI cases which were launched so far, and it demonstrated that there was a clear difference in the degree of satisfaction. Through this examine, a brand was confirmed as one of the important element of user experience in using the 3D GUI that was launched competitively by companies. Therefore, the result of this study suggest that the designers need to establish strategies that make the brand as the core subject of design during the process of manufacturing product and service.

In this paper, we present a mobile application for 'personalized customized learning' for children with articulation disorders using an artificial intelligence (AI) algorithm. A dataset (Data Set) to analyze, judge, and predict the learner's articulation situation and degree. In particular, we designed a prototype model by looking at how AI can be improved and advanced compared to existing applications from the UX/UI (GUI) aspect. So far, the focus has been on visual experience, but now it is an important time to process data and provide a UX/UI (GUI) experience to users. The UX/UI (GUI) of the proposed mobile application was to be provided according to the learner's articulation level and situation by using CRNN (Convolution Recurrent Neural Network) of DeepLearning and Auto Encoder GPT-3 (Generative Pretrained Transformer). The use of artificial intelligence algorithms will provide a learning environment with a high degree of perfection to children with articulation disorders, thereby enhancing the learning effect. I hope that you do not have any fear or discomfort in conversation by improving the perfection of articulation with 'personalized and customized learning'.

In the present study, a nonlinear model of rainfall-runoff process using Artficial Neural networks(ANNs) which have no consideration on the physical parameter for the basin was developed at Naju station which is the main stream of Yeongsan-river, and Sunam station which is the main stream of Hwangryong-river. The result from the model of ANN_NJ_9 at the Naju station revealed the best result of the rainfall-runoff process, while the model of ANN_SA_9 for the Sunam station. Also, GUI_FFS developed in the research showed the $R^2$ of more than 0.98 between the observed and predicted values using the rainfall and runoff in the respective stations. Therefore, the GUI_FFS might be expected that it can play a role for the high reliability to operate and manage the water resources and the design of river plan more efficiently in the future.
