  • This paper presents the design of the educational router system. This system is designed and implemented to support network configuration and embedded programming technology of the user on Internet. Not only Static routing protocol but also a kind of dynamic routing protocols such as OSPF and RIP and firewall have been programmed for education based on ethernet interface. ADS 1.2 as debugging environment, uC/OS-ii as RTOS and C language as development language are used. The educational procedures is compile, loading of static routing protocol, a kind of dynamic routing protocols such as OSPF and RIP and firewall program already supplied. Thereafter the verification is checked by using "ping" test to allow for demo operation such as hands-on training procedure. Finally programming procedure similar with demo operation of static routing protocol, a kind of dynamic routing protocols such as OSPF and RIP and packet filtering function is educated step by step.

  • Communication problems have been regarded as one of the biggest causes in trouble in many industries. This led to extensive research on communication as a part of human error analysis. The results of existing researches have revealed that maintaining a good quality of communication is essential to secure the safety of a large and complex process system. In this paper, we suggested a method to measure the quality of communication during off-normal situation in main control room of nuclear power plants. It evaluates the cosine similarity that is a measure of sentence similarity between two operators by finding the cosine of the angle between them. To check the applicability of the method to evaluate communication quality, we compared the result of communication quality analysis with the result of operation performance that was performed by operators under simulated environment.

  • This study was attempted to find out the effect of major satisfaction, maturation of career consciousness and clinical practice satisfaction of nursing college students on job-seeking stress. For this study, 157 3th, 4th grade students were participated from K University in K Province, using a self-reported questionnaire. Data analysis was performed using SPSS version 22.0. program. As a result of this study, it was revealed that there was a significant correlation between the job-seeking stress of nursing students on major satisfaction(r=-.270, p<.001), clinical practice satisfaction(r=-.283 p<.001), maturation of career consciousness(r=-.424, p<.001). Also, the factors affecting the job-seeking stress of nursing students were major satisfaction(β=-0.005, p<.05), clinical practice satisfaction(β=-0.126, p<.001), maturation of career consciousness(β=-0.369, p<.001) with a total explanatory power of 17.7%. Therefore consideration of educational programt be given to the s and support systems to reduced job seeking stress for nursing students.

  • Simulation system was introduced and used a lot in the fields of aviation, vessel, and medical treatment. 3D Simulation system has been used quite insufficiently as it requires a lot of system resource and huge amount of computer calculation. As the graphic card performance and simulation function developed, however, PC based simulation has been activated and is verified of its possibility as an educational software. However, educational institutions need to invest huge amount of budget and manpower to purchase and maintain CT Equipment. For such a reason, educational institutions entrust their students to hospitals for indirect experience of operation or for mere observation. This study, therefore, developed a CT Virtual reality education system with which medical CT Equipment can be directly operated in PC based 3D Virtual environment.

  • Recently, interest in programming and artificial intelligence is continuously increasing, and software education is being implemented as a mandatory education from elementary school. For efficient programming education, it is basically necessary to build a lab environment suitable for students and teachers, but there are performance problems due to the inadequacy of old computers and network equipment. Therefore, in this paper, we propose a web page-based online practice environment and algorithm competition scoring system using React and Spring boot to solve the problem of the programming practice environment. Through this, it is thought that programming learning can be carried out using only a web browser even on low-spec computers. In addition, since various programming languages can be learned irrespective of the language to be learned, it is considered that the time cost for establishing a practice environment can be reduced.

  • It is very important for beginners in networking to build, test, and operate an IP network system, which is the key infrastructure of the fourth industrial revolution. An IP network system consists of the IP network itself, covering both the internet and underlying layers, plus the basic network system supporting fundamental network services, with a DNS, the DHCP, email, WWW, and application service systems, such as VoIP. This paper suggests an open software-based practice platform with a minimal network configuration on which beginners can practice on nearly all of the IP network system, and it presents a practice scenario and results. In addition, it adds both IP address allocation and routing table manipulation functions to the network simulator software, which will allow beginners to learn table-based datagram routing schemes in advance. This platform may be useful for networking beginners in order to practice on an IP network system on their own personal computers without additional equipment and costs.

  • In this paper, to design a basic data science practice curriculum as a liberal arts subject for non-majors, we proposed an educational method using an Excel(spreadsheet) data analysis tool. Tools for data collection, data processing, and data analysis include Excel, R, Python, and Structured Query Language (SQL). When it comes to practicing data science, R, Python and SQL need to understand programming languages and data structures together. On the other hand, the Excel tool is a data analysis tool familiar to the general public, and it does not have the burden of learning a programming language. And if you practice basic data science practice with Excel, you have the advantage of being able to concentrate on acquiring data science content. In this paper, a basic data science practice curriculum for one semester and weekly Excel practice contents were proposed. And, to demonstrate the substance of the educational content, examples of Linear Regression Analysis were presented using Excel data analysis tools.

  • IT 기술의 발전은 다양한 산업에서 PLC를 기반으로 하는 스마트 팩토리의 도입이 확산되고 있는 실정이나 이를 운영하는 운영 인력의 부족으로 많은 어려움을 겪고 있기에, PLC를 사용할 수 있는 인력 양성 교육 플랫폼이 필요한 실정이다. 최근 PLC와 같은 실습 기자재를 대체할 시뮬레이션 기법의 연구가 활발하게 진행되고 있으나, 기존 PC 환경에서의 시뮬레이션 프로그램들을 원격 수업에 적용할 경우 모니터 상에 많은 요소가 디스플레이 되어 화면 전환이 불편한 단점을 가지고 있다. 본 논문에서는 시뮬레이션 프로그램을 모바일 환경에서 실행하여 PC 화면에 모니터링할 프로그램의 수를 감소시킬 수 있는 모델을 제안한다. 제안 모델을 원격 교육에 적용할 경우 화면 전환의 수를 감소시켜 더욱 정확한 이해를 통하여 학습의 효과를 향상시킬 수 있을 것으로 기대된다.
