As online learning continues to be extended, many engineering colleges are engaged in online learning activities. One of the core competencies required of engineering students in a knowledge-convergence society is communication skills. Online discussion activities are frequently used in educational field to improve communication skills. Efforts are being made to provide visual dashboards in online discussion activity systems to more effectively support online discussion activities. However there is less qualitative studies on students' experience in discussion activities. The purpose of this study is to explore the experience of engineering students participating in discussion activities using online discussion systems and visual dashboards. We interviewed 15 students who participated in online discussion activities to achieve their research objectives about their experience in utilizing the online discussion system, their perception of visual dashboards, and their experience in discussion activities. As a result of the study, students' perception of the use of the online discussion activity system, the visual dashboard, and the perception of a sense of social presence were understood. To be more effective in providing tool support, such as discussion activity systems and visual dashboards in online discussion activities, instructors need to understand the nature of learners' online discussion activities.

Recently, a new theoretical and methodological approach for computational science is becoming more and more popular for analyzing and solving scientific problems in various scientific disciplines such as Computational fluid dynamics, Chemistry, Physics, Structural Dynamics, Computational Design and applied research. Computational science is a field of study concerned with constructing mathematical models and quantitative analysis techniques and using large computing resources to solve the problems which are difficult to approach in a physical experimentally. In this paper, we present R&D of EDISON open integration platform that allows anyone like professors, researchers, industrial workers, students etc to upload their advanced research result such as simulation SW to use and share based on the cyber infrastructure of supercomputer and network. EDISON platform, which consists of 3 tiers (EDISON application framework, EDISON middleware, and EDISON infra resources) provides Web portal for education and research in 5 areas (CFD, Chemistry, Physics, Structural Dynamics, Computational Design) and user service.

최근 스마트폰이 급격하게 발달함에 따라 많은 사람들에게 보급화 되었다. 스마트폰의 다양한 기능과 휴대성은 대중화의 시발점으로 많은 사람들에게 편리함을 제공해주고 있다. 이에 사용자들이 가장 기초적으로 사용하는 문자 입력을 보다 편리하고 신속하게 입력하기 위한 방법들에 대한 많은 연구 및 응용 프로그램 개발이 활발히 진행되고 있다. 하지만, 많은 키패드가 만들어졌음에도 불구하고, 사용자가 습득하기 위한 지연시간이 발생될 뿐만 아니라, 오타가 빈번하게 나타나고 있다. 본 논문에서는 스마트 UI/UX를 통해 최소 한 번의 누름으로 문자 및 문장을 완성할 수 있는 SUI-K를 제안한다.

IT 발전의 빠른 진보성으로 인해 탄생된 스마트 디바이스는 급격한 대중화가 이루어지고 있다. 많은 사람들이 편리한 기능과 휴대성을 갖춘 스마트 디바이스에 의존하게 되면서 개인 정보 보호를 위한 화면 잠금 기능 연구가 활발하게 진행되고 있다. 이에 사용자들은 다양한 화면 잠금 기능을 선택하여 설정 할 수 있다. 다양한 화면 잠금 기능 중에 패턴 락은 직관적인 인터페이스로 인한 편리함과 보안성으로 인해 많은 사용자가 사용하고 있다. 하지만, 패턴 락은 한정된 화면 잠금 패턴 기능을 가지고 있으며 화면 잠금을 해제하는 경우에 쉽게 타인에게 패턴이 노출된다. 이에 본 논문에서는 8-방향성을 기반으로 동작하고 패턴 락의 한정된 패턴 수와 타인에 대한 패턴 노출을 개선하여 보안성을 높인 SDL(Smart Device Lock)-8way를 제안한다.

In this thesis. we present the cyber lecture system based on XML 3-tier that uses the communication network as the internet. The system was designed to analysis the existing cyber lecture system and its details and to examine web system architecture and XML 3-tier model. With the designed system, we developed the cyber lecture system. We tested the existing system for performance and problem, then we improved the method of the cyber lecture system used by XML 3-tier Model. The cyber lecture system is offered the handiness of the cyber lecture system using web interface.

This paper presents an approach for assuring course completion structure of the project courses by the requirements of KCC2010 engineering criteria. The proposed approach describes the way that courses of project are completed in a systematic using the gate model that is given the opportunity to take next project course by the course outcomes of project course taken. Results of assessments on 'Software Project I' course shows that it is important to protect the withdrawal of student who undergo retraining by efforts of professor course responsible to assure course completion structure of the project courses.

In this paper, we looked around an effective teaching plan base on the LabVIEW by utilizing the USB type DAQ device. Moreover, we have been learning the concept of control and instrumentation engineering through theory and practice classwork in the various field of engineering, come to automation engineering as well as electricity, electronic, telecommunication and computer science. In case of the best learning to understand the concept and operate the practice, we'd like to propose the application technique to make use of the PC based on LabVIEW software with USB type DAQ devices, better than to depend upon the expensive equipment as before. As a result, we hope that this technique to be considered easily accessible to understand anyone and expect distinguished applications.

This paper is the second part of the January 2018 issue of the Korean Society for Engineering Education, The "Equilibrium and Unbalance Analysis of Taegeuk Pattern DNA Matrix Codes," and is an extension of the paper published in the IoT Section of the 2017 Summer Conference in Jeju. In this paper, we have reviewed the history of what is life, and 5G Mobile communication: with IoT followed by recent research on influenza RNA gene mutation and DNA mutation variants, and the insights of Watson and Crick. Inspired by a single Franklin DNA X-ray diffraction photograph, they received the Nobel Prize for the Nature publication of DNA that has three patterns and regular repeatability. Professor MoonHo Lee has solved the three patterns in Diagonal, Left to Right, and Vertical matrices in a 2x2 matrix[CU; AG] and A = T = U = 30% C = G = 20%. We also proposed DNA Watch. This is the Healthcare IoT, which is seen by the DNA Watch on the wrist, the type of Tai Chi pattern of the body, and is immediately connected to the smartphone and delivered to the doctor.

For smart manufacturing, most semiconductor sites utilize automated material handling systems(AMHS). As one of the AMHSs, the OHT control system(OCS) manages overhead hoist transports(OHT) that move along rails installed on the ceiling. This paper proposes a real-time scheduling system to efficiently allocate and control the OHTs in semiconductor logistics processes. The proposed system, as an independent subsystem within the OCS, is interconnected with the main subsystem of the OCS, so that it can be easily modified without the effect of other systems. To develop the system, we first identify the functional requirements of the semiconductor logistics process and classify several types of control scenarios of the OHTs. Next, based on SEMI(Semiconductor Equipment and Materials International) standard, we design sequence diagrams and interface messages between the subsystems. The developed system is interoperated with the OCS main subsystem and the database in real time and performs two major roles: 1) OHT dispatching and 2) pathfinding. Six integrated tests were carried out to verify the functions of the developed system. The system was normally operated on six basic scenarios and two exception scenarios and we proved that it is suitable for the mission planning of the OHTs.
