  • This study attempted to confirm the reading behavior of Generation Z college students in Korea, including their perception of e-book use, and to find out the changes caused by COVID-19. To this end, university students across the country were surveyed for e-book recognition and use, e-book usage status, e-book preference recognition, and comparison items of university libraries and e-book use before and after COVID-19. As a result of the analysis, university libraries had a significant impact on the use of e-books by Generation Z college students, and COVID-19 partially affected reading behavior, such as a significant change in the average daily reading time of Generation Z college students.

  • This paper deals with the measurement and analysis of radio characteristic of 424 MHz for using the automation of transmission and supply of electric power, ana automatic meter reading(AMR). Normally radio propagation characteristic is the base of system design, performance evaluation and choice of position of the base station in wireless communication. It is the most accurate way to design a base station through practical measurements, but it costs much time, money and engineers. So, we developed 424 MHz short range wave propagation model for AMR service.

  • An anemometer employing the bulk PTC thermistor as the sensing element is investigated in this study. The numerical and experimental works are carried out to improve the sensitivity problem of the element by focusing fluid dynamics point of view. The typical shape of the sensing element has been used as a rectangular type, but this shape has a sensitivity problem because of flow separations on the sharp edge when the flow direction is different from that of the sensing element. In order to reduce the reading error, the installer has to be very careful about the flow direction. The reading error fluctuation by time as well as the sensitivity problem can be improved considerably through this study. It can be concluded that the small change of the sensor shape can improve the performance of the flow sensor.

  • A novel self-reference sense amplifier with parallel reading during writing operation is proposed. Read access time is improved compared to conventional self-reference scheme with fast operation speed by reducing operation steps to 1 for read operation cycle using parallel reading scheme, while large sense margin competitive to conventional destructive scheme is obtained by using self-reference scheme. The simulation was performed using standard $0.18{\mu}m$ CMOS process. The proposed self-reference sense amplifier improved not only the operation speed of less than 20 ns which is comparable to non-destructive sense amplifier, but also sense margin over 150 mV which is larger than conventional sensing schemes. The proposed scheme is expected to be very helpful for engineers for developing MRAM technology.

  • The Saemaul Mini-Library system had to start as a purely voluntary grass-roots movement without a tax su n.0, pport. In other words, it had to depend on voluntary contributions in time and labor by the reading club members for its finance and daily maintenance and operation. The purpose of the study is to analyse the actual condition of a Saemaul Mini-Library, which is established in a rural and a fishing village. To meet this purpose, I will survey the function and the meaning of a Saemaul Mini-Library and the main tendency of it-now did it start and how did it develop and I will analyse the general condition of structural factors (establishment, materials, reading club) in a Saemaul Mini-Library.

  • This paper describes our high-density near-field optical recording using bent cantilever fiber probes installed in an atomic force microscope. We conducted a near-field reading of nano-scale hole patterns with a 100 nm spatial resolution and a 25 ${\mu}m$/s scan speed; this implies a capability of a data reading density of 60 Gb/$in^2$ with a 0.25 kbps data transfer rate. In addition, we investigated re-writable near-field recording on photochromic diarylethene films. We successfully recorded erasable memory bits having a minimum width of 600 nm in a writing time as short as 30ms. We found that using a cantilever probe simplifies the setup and operation of the near-field optical recording system and may offer multifunctional recording capabilities.

  • The use of Information and Communication Technologies (ICT) is the key to operate a change from the traditional manual reading of water meters and sensors to an automated system where high frequency data is remotely collected and analyzed in real time, one of the main components of a Smart Water Grid. The recent boom of ICT offers a wide range of both wired and wireless technologies to achieve this objective. We review and present in this article the most widely recognized technologies and protocols along with their respective advantages, drawbacks and applicability range which can be Home Area Network (HAN), Building Area Network (BAN) or Local/Neighborhood Area Network (LAN/NAN). We also present our findings and we give recommendations on the application of ICT in Smart Water Grids and future work needed.

  • 입모양 인식(Lip Reading) 기술은 입술 움직임을 통해 발화를 분석하는 기술이다. 본 논문에서는 일상적으로 사용하는 10개의 상용구에 대해서 발화자의 안면 움직임 분석을 통해 실시간으로 분류하는 연구를 진행하였다. 시간상의 연속된 순서를 가진 영상 데이터의 특징을 고려하여 3차원 합성곱 신경망 (Convolutional Neural Network)을 사용하여 진행하였지만, 실시간 시스템 구현을 위해 연산량 감소가 필요했다. 이를 해결하기 위해 차 영상을 이용한 2차원 합성곱 신경망과 LSTM 순환 신경망 (Long Short-Term Memory) 결합 모델을 설계하였고, 해당 모델을 이용하여 실시간 시스템 구현에 성공하였다.

  • This study is an example of a class of bibliotherapy through Lee Chung-joon's novel Snowy Road. Bibliotherapy proceeds through the process of identification, catharsis, output, insight, and application through reading. Through research, students objectively examine the situation of the character in the novel and compare it with their own situation. Students evaluate the situation of the character in the novel, experience the various life positions of the character in the novel by answering "What would you do if I were a character in the novel," and express their willingness to live differently from their lives. At the same time, I look into my relationship with my parents and seriously think about whether there is a problem and how to solve it if there is one. Through this process, students specifically suggest ways to think about and solve their emotions and problems. In the end, students' hurt feelings can be partially or sufficiently healed through reading. Through this study, it is expected that the method of bibliotherapy will be more concrete and develop in a positive direction.
