To assess the preference and efficacy of empirical fitting methods with spheric and aspheric RGP lenses. Methods: Healthy 37 subjects were fitted with spheric design (diameter 9.3 mm) on right eye and aspheric design (dia 9.6 mm) on the left eye. Base curves which were fitted empirically (using on-K, Kavg-0.50D (or 1.00D) and manufacturer's recommended fitting guide) were compared with another base curve which obtained the best diagnostic fit with spheric and aspheric RGP lenses. The preference and fitting type (lid attachment or interpalpebral) for two design lenses were investigated 2 weeks after fitting RGP lenses. Results: Of 33 successful RGP lens-wearing subjects, 76% preferred spheric design compared with 24% of aspheric RGP lens wearers. Sixty seven percent were fitted with lid-attachment in spheric lenses, whereas 64% were fitted with lid-attachment in aspheric lenses. The acceptable fit success rates within ${\pm}$0.50D of base curves were 97% for the on-K fit, 100% for the Kavg-0.50D fit and 100% of the manufacturer's guide fit compared with the diagnostic fit in spheric design, whereas 91%, 79% and 94% reported on-K, Kavg-1.00D and manufacturer's guide, respectively, in aspheric design. Conclusions: Although aspheric RGP lenses are more popular in the Korean market, it is still preferable to fit subjects with spheric RGP lenses. Empirical fitting may be best accomplished with the spheric lenses using Kavg-0.50D fit and the manufacturer's fitting guide, whereas aspheric RGP lens designs are unacceptable lens fit based on empirical fitting.

In recent days, when the development in smartphones has made it common to operate objects by using them, this study aimed to present a guideline for the UI/UX designs for applications which are necessary for operating various objects through the wireless communication technology. To suggest the application guideline, existing object control application case studies were analyzed, and based on this investigation the object control application UI/UX design guidelines were proposed. This study classified the types of wireless connections used by smartphones (LTE, Wi-Fi, Bluetooth, NCF, RFID) and analyzed the necessary design factors for operating objects by each type. Based on such analysis, this study presented the design sequence, factors, and methods for the UI/UX guidelines of applications. First, the method of connection was selected; second, the control device was selected. This new direction for designing smartphone applications for operating objects will likely help systemize the design process and enable the user to operate the object more intuitively. In future research, case studies will be designed applying the guidelines suggested from this study.

There are a great number of difficulties without Interface Guideline, even though the utility of the web in the educational field has been increased. In spite of having a guideline there still remains problems, when the researcher develops a practical web design, because of uniformity and universality. The purpose of this research will give a good model and a guideline, developing a way of web-site assessment through psychological language. First, the researcher has to induce psychological language and recognize the relevance of the principle of device system. Second, they should build an assessment model based on an established system of classification. As a result, they recognized that an assessment model based on the system of psychological language can help in working out authentic design problems. The designer faces many difficulties when using Interface Guideline for the sake of the existing software developer because of specific terminology. On the contrary, these days, the guideline of psychological language system provides the designer with easy comprehension of language and also able to perceive problems in advance. In addition, the researcher can realize that it can be used, as a good source and data.

Since the 1960s, as de-institutionalization for the disabled advanced, the concept of integration for the disabled and the non-disabled has gradually developed as well. Despite efforts to improve various welfare policies for the disabled, their satisfaction level in culture and leisure activities has not significantly increased. This study aims to analyze the 10 selected design guidelines dealing with disability in order to diagnose the current status of the guidelines adaptable to inclusive park design, which can provide opportunities to access natural and cultural public spaces. From the users' point of view, the guidelines turn out not to have a balance between the disabled and the non-disabled in terms of the usage of certain spaces and they heavily focus on physical disability in adult ages. From the planning and design aspect, a specified design process is overlooked. Amenities/facilities and programs, layout and zoning are only mentioned while they are very specific about accessibility and mobility. It is necessary to establish the concept and goal of inclusive parks, and to provide specialized guidelines for inclusive parks from a more balanced perspective.
