Purpose: The purpose of this study is to identify the difference in toilet approach way by wheelchair users according to the direction of the door and to suggest the layout of the toilet rooms most accessible to the wheelchair users. Methods: Survey to wheelchair users about approach to toilet have been conducted for the data collection. 90 answers have been analyzed statistically by SPSS 19.0 program. Results: The conclusions of this study are as follows. Firstly, spinal cord disorders prefer diagonal approach and lateral approach to the toilet, but brain lesions prefer diagonal approach and frontal approach to toilet. Secondly, the manual wheelchair users prefer the diagonal approach and the lateral approach to the toilet, and the electric wheelchair users has a different approach way to the toillet depending on the direction of the door. Finally, the layout of accessible toilets have to be designed for the diagonal approach to toilet, which is most preferred by wheelchair users. Implications: The toilet approach varies according to the disability types and the wheelchair types. Therefore, the size of accessible toilets should be larger than now considering the access of variety wheelchair users.

An 8-year-old spayed Yorkshire Terrier Dog was presented to the Veterinary Teaching Hospital of Kyungpook National University because of the recurrent superficial pyoderma. At the presentation, pustules and papules were present throughout the body. Numerous rods with a few cocci were observed on impression smears and they were confirmed to be Proteus mirabilis and Staphylococcus pseudointermedius consecutively. The patient was treated with systemic enrofloxacin and amoxicillin-clavulanic acid based on the results of antimicrobial sensitivity tests with once a week basis 4% chlorhexidine shampoo. An excellent clinical response was achieved in 2 weeks of therapy and the lesions were fully resolved in 6 weeks. The possibility of P. mirabilis infection should not be overlooked by clinicians in dogs with recurrent superficial pyoderma although it's been considered to be rare.

This paper presents the comprehensive transformer design methodology with the winding method of automatic type suitable for LLC resonant converter. The problem with conventional LLC resonant transformer is that it is difficult to implement the winding method of automatic type because all windings are wound in one bobbin. Therefore, the LLC resonant transformer, which is capable of the winding method of automatic type to multiple section bobbin without insulation tape and barrier tape, is proposed in this paper and the design procedure of the proposed LLC resonant transformer is also shown. Modeling and analysis of the proposed LLC resonant transformer using Maxwell 3D simulation tool are described in detail and a protype 150W LLC resonant converter using the proposed LLC resonant transformer manufactured by 3D modelling is also verified through the experimental test.

In modern life, interior decoration has been transformed into a psychological synergistic effect of space, greatly affecting human sensibility. The main point of view in this paper is to study the discovery of new decorative effects and the possibility of products that can replace imported tiles, which account for more than 60% of the walls of indoor spaces closely related to daily life. The solution is to create point tiles using color glass plaster techniques developed in 2018 and to explore the possibility of decorating art walls to meet consumers' purchasing needs using simulations. The four patterns applied to the a paintbrush, resist printing, cutting technique, and inlaid patterns, and the traditional color development effect of the medium color suited to our sensibilities was studied. In addition, through simulation, art walls and acrylic using color glass styles were also used in the kitchen, living room and empty space of the bathroom. Based on this research, ceramic point tiles with a new perspective will be explored and the interior using walls will be activated.

The purpose of this study is to provide a cultural and artistic content guide service that can provide customized guides according to the disability status of the disabled who consume cultural and artistic contents. It is designed to provide a more individualized service through user input of disability information including the type and degree of disability of the disabled, the type of cultural and artistic content desired by the disabled, and information on the cultural and artistic level of the disabled. In addition, it is not limited by time and place, and it has the distinction of providing appreciation of cultural and artistic contents and commentary information of the corresponding cultural and artistic contents in various ways on the application. In particular, to provide cultural and artistic contents differently by identifying the type or degree of disability of the user, or to provide cultural and artistic contents with different expertise in consideration of the user's cultural level and taste, and to improve the cultural level. The most special feature is that it provides recommended content in consideration of the difficulty of art content. User analysis was conducted through in-depth interviews and persona techniques. As a result of the analysis, the needs for the enjoyment of culture and arts are also increasing among the disabled, while the services that reflect those needs are very insufficient. Therefore, all interviewees stated that they are willing to actively utilize these services if they are released. In the future, it is necessary to increase the accessibility of the disabled to culture and arts by developing various services using new ICT technologies.

It is essential to make a purchase decision to make sure that the furniture matches well with other structures in the room. Moreover, in the Untact Marketing situation caused by the COVID-19 crisis, this is becoming an even more impact factor. Accordingly, methods of measuring length using AR(Augmented Reality) are emerging with the advent of AR open sources such as ARCore and ARKit for furniture arrangement interior simulation. Since this existing method using AR generates a Depth Map based on a flat camera image and it also involves complex three-dimensional calculations, limitations are revealed in work that requires the information of accurate room size using a smartphone. In this paper, we propose a method to accurately measure the size of a room using only the accelerometer and gyroscope sensors built in smartphones without using ARCore or ARKit. In addition, as an example of application using the presented technique, a method for applying a pre-designed room interior to each room is presented.
