Scratch-based programming has come to be known as an effective programming tool because of its graphic instruction modules, which are designed to be assembled like the famous LEGO building blocks. These building block-like structures allow users to more easily program applications without using other more difficult programming languages such as C or Java, which are text-based. Therefore, it poses a good opportunity for application in educational settings, especially in primary schools. This paper presents an effective approach to developing an educational robot for use in elementary schools. Furthermore, we present the method for scratch programming based on the external modules need for the implementation of robot motion. Lastly, we design a systematic curriculum, titled "Play with a Robot," and propose guidelines to using the educational programming language Scratch.

Due to the development of science and technology in the 4th Industrial Revolution, a variety of content is being developed and utilized through educational courses linked to digital textbooks. Students use smart devices to engage in realistic virtual learning experiences, interacting with the content in digital textbooks. However, while many realistic contents offer visual and auditory effects like 3D VR, AR, and holograms, olfactory content that evokes actual sensations has not yet been introduced. Therefore, in this paper, we designed and implemented 4D educational content by adding the sense of smell to existing content. This implemented content was tested in classrooms through a curriculum-based evaluation. Classes taught with olfactory-enhanced content showed a higher percentage of correct answers compared to those using traditional audio-visual materials, indicating improved understanding.

본 연구는 방송콘텐츠를 일방향적인 정보전달도구의 차원이 아닌 풍부한 내용이 담긴 소프트웨어, 즉 단순히 정보를 제공하던 것에서 지식구성과 창출 과정을 촉진하는 학습자원으로서의 가능성에 주목하고, 이러한 가능성을 e-Learning의 교수 학습모형 중에 하나인 e-PBL을 통해 구체적으로 구현해 보고자 했다. 이를 위해 온라인 학습환경 설계 및 개발에 무게중심을 두고 연구를 진행했다. 특히, 본 연구는 온라인 학습커뮤니티 개발을 비롯하여 방송콘텐츠의 활용을 극대화하기 위한 전략적 방안들이 집약된 학습모듈 설계 및 개발과정에 초점을 두었다. 또한 이를 적용하고 그 타당성을 검증함으로서 학습모듈이 갖는 차별성을 증명하고자 하였다.

Purpose: This study aimed to review the recent scientific literature regarding nursing care of arteriovenous fistula (AVF) for the patients with Chronic Renal Failure (CRF) undergoing hemodialysis. Methods: An integrative review was conducted and articles were searched from Cochrane library, Medline, PubMed, Science direct and CINAHL databases by using the terms "nursing", 'Chronic Renal Failure', 'Haemodialysis', renal failure', 'or 'AV Fistula' nursing care', 'self-care'. The inclusion criteria were articles published in English in the year of 2015-2020 with availability of free full text. Reviewed data were carefully analyzed and charted regard to the nursing care of the patient with AVF. Results: 12 articles papers met the inclusion criteria. Three themes were derived from the data: (a) Intervention (b). Patient and nurse education (c) KPA Assessment of (Knowledge, Practice and Attitude) Conclusions: This review indicates the challenges that nursing care of AVF patients undergoing hemodialysis. The identified themes can be used in the development of more effective educational- programs. Future studies should focus on the development and evaluation of educational programs that include these selected themes.

As technological development is progressing recently, various technologies are actively being studied in the course of the 4th industrial revolution. So, even in the educational field, virtual reality and augmented reality technology are used in educational environments, but specialized additional equipment is required and the price is very expensive. Also, since a plurality of equipment are required for a large number of people, it is urgent to study the technology that can be effectively applied to the industrial education field. So in this paper, we propose an industrial training system for HMD-AR, MPEG-DASH and SOAP based HTTP based Live Machinery Operation using Smartphone to solve the problems of existing system.

Demands for developing diverse teaching methods and materials which can lead to active participation of students in classes have been emerged for environmental education in secondary schools. In order for more effective environmental education, a variety of programs in the mass media including public broadcasting have been used. Advantages associated with the broadcasted TV programs include compensation of temporal and spatial limits embedded with the printing media, improvement of studying efficiency, and provision of diverse studying opportunities, leading to the promotion of the awareness of environmental issues. In this study, 256 environmental issues related TV programs being aired via major public broadcasting companies such as EBS, KBS, MBC and SBS between years of 2003 and 2004 were analyzed. During the present research, selection of the programs was made based on the weight of the environmental issues in independent programs being aired for at least 10 minutes. A survey as a primary means was carried out for the utilization of the audio-visual educational materials in order to provide a new method employing the TV programs which were related to the environmental issues during the instruction in secondary schools.

This paper presents a smartphone application for the clinical practice education conducted in hospitals, with an aim to evaluate its effectiveness. A nonequivalent control group posttest design was used, which included a total of 100 nursing of school students who conducted their clinical practice. They were divided into one control and one experimental group (50 students each). The control group was directly trained in the clinical practice orientation, and the experimental group was a group who self-learned the clinical practice orientation using a smartphone application. Research data were collected between March 5 and April 27, 2019. They were analyzed with descriptive statistics and independent t-test, using the SPSS Statistics Version 24. The smartphone application customized for the clinical practice education was implemented through the following four phases: analysis, design, development, and evaluation. The developed application was registered in Google Play (for Android apps) and Apple Store, and related information was provided, making it available for download. The study showed that the satisfaction with and self-confidence in learning differed significantly between the groups. However, technology acceptance and knowledge acquired through practice showed no statistically significant difference. The research results serve as basic data for applying smartphone applications as an educational method that can replace traditional modes of education, serving as a significant indicator of the education delivery method diversification.
