Mindmap is effective method to analyze informations. And, through mindmap, students can be able to grow their ability of logical reconstruction. In Modern society, people have been developing IT technology and variety of portable devices. So, Educational environments have been being changed accordingly, too. In this study, we have implemented mindmap application that based on android to share the group member's thinking. To effective sharing, we have used mindmap technique and photo attachment feature. In this study, expert evaluation has been carried out by elementary current teachers. In result of this expert evaluation, we have obtained positive feedback at sharing function, input technique and information display. Also, teachers have gave feedbacks that they are willing to use this application in class, if classroom environment is possible.

The purpose of this study is to grasp the application tendency of interior accessories in Korean residential spaces. The main resources were selected documents and articles with pictures published 27 years, from 1976 to 2002, in Modern House, which is the first magazine for the residential space in Korea. The major findings are summarized as follows: 1) Interior accessories were investigated more for functional reasons than decorative reasons. Despite the belief that interior accessories are Primarily for decoration purposes, this study proves that the functional elements are more important as part of the Korean interior. 2) The kind and the amount of interior accessories applied in residential space were decreasing in most accessories as well as in master bedroom, and living rooms from 1994 to 2002. 3) The number of application to Korean traditional accessories in residential space decreases as time goes by. Although they were used as functional accessories as the role of antiques in present.

Maximum short circuit current of modern power system is becoming so large that the current should transmission capability. Although there are various kinds of method to solve this, approached from super conductivity Fault Current Limiter application viewpoint among them. High Temperature Superconductor-Fault Current Limiter (HTS-FCL) development is progressing according to HTS technology development, and system application is tried. For actual system application of such super conductivity FCL, an efficient method to find FCL locations suitable for reduction of short circuit currents of more than one fault location is developed.

Most current 3D digital maps are 2.5 dimension models based on DEM, which can only be recognized, browsed and operated by a special software, far from meeting the needs of a modern digital city (global) with the distributed, isomerous and multiple application on the real 3D representation and open sharing models. In this paper, a new generation digital city oriented 3D digital map is studied. Firstly, a real 3D digital map representation is presented. And then, some key techniques and methods for browser-based 3D digital map’s representation, display and operation are introduced, which can realized the open sharing of 3D map in distributed, isomerous and multiple application environment. Furthermore, the scale driving technique of proposed 3D digital map is also studied. And currently, some developments based on some of the above methods are being carried to provide key and general platform for other application software’s development.

M-learning is one of the most important modern learning environments in developed countries, especially in the context of the COVID-19 pandemic. According to the Ministry of Education policies in Saudi Arabia, gender segregation in education reflects the country's religious values, which are a part of the national policy. Thus, it will help many in the target audience to accept online learning more easily in Saudi society. The literature review indicates the importance to use the UTAUT conceptual framework to study the level of acceptance through adding a new construct to the model which is Mobile Application Quality. The study focuses on the end user's requirements to use M-learning applications. It is conducted with a qualitative method to find out the students' and companies' opinions who working in the M-learning field to determine the requirements for the development of M-learning applications that are compatible with the aspirations of conservative societies.

Insomnia is one of the most common sleep disorders experienced by modern people, and treatment is often not adequate due to various limitations. Digital therapeutics for insomnia are expected to play a revolutionary role in supplementing and satisfying unmet needs in real-world clinical treatment. Digital therapeutics for insomnia were developed based on cognitive-behavioral therapy for insomnia, which is the first standard treatment for insomnia. The effectiveness of digital therapeutics for insomnia developed by several companies has been proven through well-designed clinical research. Various approaches have been used for practical application of digital therapeutics for insomnia. Thus far, meaningful results have been drawn, but there are areas that need to be improved upon based on real-world evidence. Sleep researchers need to validate the safe and effective application of digital therapeutics for the treatment of insomnia.

Objectives In this study, we tried to analyze the expression status and diagnostic application of the disease according to the characteristics of Six Qi. Methods Suwenxuanjiyuanbingshi (Exploration to Mysterious Pathogenesis and Etiology Based on the Plain Questions, 1152), Shoushibaoyuan (Longevity and Life Preservation, 1615), Dongeuibogam (Treasured Mirror of Eastern Medicine, 1613) and two modern works on Six Qi were analyzed for this study. Results Some substrate characteristics presenting Six Qi were extracted from original literatures. Also, we found that the characteristics of Six Qi can be applied to clinical trials by presenting them as three criteria as wind, humidity, and temperature. Conclusions This study suggests.

In this article, the fundamental concept, characteristics and application potentials of coreless printed-circuit-board (PCB) transformers are described. Coreless PCB transformers do not have the limitations associated with magnetic cores, such as the frequency limitation, magnetic saturation and core losses. In addition, they eliminate the manual winding process and its associated problems, including labor cost, reliability problems and difficulties in ensuring transformer quality in the manufacturing process. The parameters of the printed windings can be precisely controlled in modern PCB technology. Because of the drastic reduction in the vertical dimension, coreless PCB transformers can achieve high power density and are suitable for applications in which stringent height requirements for the circuits have to be met. A transformer's power density of $24W/cm^2$ has been reported in a power conversion application. When used in an isolation amplifier application, coreless PCB transformers tested so far enable the amplifier to achieve a remarkable linear frequency range of 1MHz, which is almost eight times higher than the frequency range of 120kHz in existing Integrated-Circuit products. PCB materials offer extremely high isolation voltage, typically from 15kV to 40kV, which is higher than many other isolation means such as optocouplers. It is envisaged that coreless PCB transformers can replace traditional core-based transformers in some industrial applications. Their application potentials deserve more attention and exploration.
