This paper presents a method to suppress multipath induced by pulses using supervised learning. In modern electronics, pulses have been used for various purposes such as communication or distance measurements. Like other signals, pulses also suffer from multipath. When a pulse and a multipath are overlapped, the original pulse shape is distorted. The distorted pulse could result in communication failures or distance measurement errors. However, a large number of samples available from a pulse can be used to effectively reject multipath by using a supervised learning method. This paper introduces how a supervised learning method can be applied to Distance Measuring Equipment. Simulation results show that multipath induced distance measuring error can be suppressed by 10 ~ 45 percent depending on the allowed pulse shape variation allowed in a standard.

Concrete carbonation is one of the factors that reduce the durability of concrete. In modern times, due to industrialization, the carbon dioxide concentration in the atmosphere is increasing, and the impact of carbonation is increasing. So, it is important to understand the carbonation resistance according to the concrete compounding to secure the concrete durability life. In this study, we want to predict the concrete carbonation velocity coefficient, which is an indicator of the carbonation resistance of concrete, through the deep learning algorithm, and to find the activation function suitable for the prediction of carbonation rate coefficient as a process to determine the learning accuracy through the deep learning algorithm. In the scope of this study, using the ReLU function showed better accuracy than using other activation functions.

The characteristic aspects of learning a foreign language require special resources and tools for online learning. Criteria for choosing educational platforms depend on key elements of an academic subject area. Microsoft Teams (hereafter, MT) educational platform is competitive one because it meets most of the needs that arise during the formation of a secondary linguistic persona. Due to the large number of corporate programs, there are a successful acquisition of language skills and the implementation of all types of oral activities of students. A significant MT advantage is the constant analysis and monitoring of the platform of participants' needs in the educational process by developers. The article highlights MT advantages and disadvantages. The attention is drawn to individual programs, which, in the authors' opinion, are the most successful to learn writing, reading, speaking, listening, as well as organize classes that meet needs of modern foreign students.

When it comes to the value of modern education, teachers are required to perform the role of a helper to promote interaction between learners, the role of a manager to facilitate smooth learning, and the role of a guide who has expert knowledge in the learning contents. Therefore, this study investigated what kind of learner-centered teaching methods there are, which require teachers to perform the roles of helper, manager, and guide, and conducted a pedagogical research on coding education to explore class models for self-directed learning. Subsequently, a class model was proposed by applying the flipped learning and havruta learning to a coding class. In this study, the learner-centered education methods of flipped learning and havruta method were applied to constructing a coding class as a university general education course. The feature of this class is that it enables dynamic interaction between teachers and learners as well as active interaction between leaners in a classroom instruction. After applying the proposed method to the actual class and analyzing it, the students taught using suggested method were more positively assessed in learning interest than those taught using a traditional method. And that in academic achievement as well, suggested method was more effective.

A modern museum has been changed from a passive place for simply exhibiting arts and antique collections to an interactive place for learning and experiencing culture and information. Such a functional change of the modern museum requires not only reorganizing fundamental characteristics of the modern museum, but also reforming organization of management teams, changing attitudes of staffs and assigning new roles to staffs for accepting the new thought and approach of visitors. That is, the function of the modem museum is not limited to collect arts and antique collections. The fundamental change of the modern museum further requires using the collections as a tool or a medium to provide a cultural exchange between the visitors and the museum, and to give new experience and information to the visitors. After proposing discussion that ' how, what, who is related to the museum? ', the way of thinking the museum is changed from ' collection ' to ' communication '. The change of the modern museum improves an educational role of the museum, and makes the museum as a communicator exchanging information and experience with visitors. In the last analysis, the modern museum is not just an exhibition medium that simply transfers information of the exhibition mediums to public. The modem museum is also a communication medium in order to collect information and transfer the collected information to the visitors. That is, the modern museum should provide various exhibition and communication mediums to the visitors for exchanging information and cultural experience. Therefore, the modern museum requires additional functions processing information suitable to the present environment and level of the museum, and transferring the information to public.

The materials on the development of modern architecture in Korea are being collected and organized in a systemic fashion. However, this is not the case with the materials relative to interior design. They are gradually disappearing or being lost. In particular, no serious attempt has yet been made to determine the characteristics and historic value of the interior design of the modern bank buildings. The purpose of this study is to trace the disappearing legacy of the interior design of modern bank buildings by learning the inner space arrangements of these buildings and the characteristics of modern interior design in order to determine the historic significance of modern commercial interior design. Banks of relatively large scale were selected for the purpose of this study. They consisted of: Chosun Bank(1911) and its Andong, Wonsan and Cheongjin branches; Chosun Shiksan Banks and its Busan, Daegu and Pyongyang branches; the Busan branch of the 18 Bank; Dongil Bank, Chosun Savings Bank(1935) and their branches. The study focused on the space arrangements and design characteristics of these banks. Although they aimed at modernization in designingtheir interior spaces, the modern bank buildings were not representative of any particular style of interior design. While western style designs were prevalent, eclectic designs incorporating many different styles existed. The characteristics of the interior design of banks of the time included installation of such decorations and use of high quality construction materials for interior and exterior expressing the wealth as to create an aura of credibility for the banks, while the floor arrangements were relatively stereotyped and simplified.

To accommodate today's higher education student, fewer textbooks are printed and more are becoming digital. Keeping with the modern era, hybrid versions of textbooks have all end-of-chapter assessment content moved to digital learning systems such as MindTap$^{TM}$ by Cengage $Learning^{(R)}$. In this work, we introduce new pedagogical strategies to combat academic e-cheating, specifically cheating on assessments given in online astronomy courses. The strategies we present in this work are employed in Horizons: Exploring the Universe, Hybrid, 13th Edition, and Universe, Hybrid, 8th Edition, by Seeds, Backman, and Montgomery.
