With the recent growth of information technology, various literacy such as digital literacy, data literacy, AI literacy is being studied. In this paper, we focus on data visualization literacy as visualization is an essential part of big data analysis and is used in several mobile apps. Visualization Literacy Assessment Test(VLAT) was developed in 2016 and we introduce how the test was developed and modified to a Korean version, K-VLAT. K-VLAT is consisted of 12 visualizations and 53 questions through a website. Additionally, to understand the research trend in visualization literacy we analyzed 81 papers that had cited the VLAT publication. We categorized the research into 4 categories with 11 sub-categories. The area of studies visualization literacy related to was understanding the relation with cognition, expanding the literacy measures, relation with education, utilization for developing user-centric dashboards or using the test to show effectiveness of visualizations. At last, we discuss about different ways to utilize K-VLAT for future research.

Government agencies and companies are establishing and promoting digital transformation strategies in various industrial fields, and are leading the era of the 4th industrial revolution through successful technological innovation. In this time of change, we can see many stories of global companies Nike and Starbucks as successful examples of digital transformation. These two companies are showing successful results through digital transformation. Domestic companies are also conducting digital innovation based on mobile, cloud, IoT, artificial intelligence, and AR/VR technologies, and are establishing RPA (Robotic Process Automation) processes for high efficiency and high productivity. In this paper, we introduce the 3D digital twin space construction automation process technique using data from the entire construction cycle of design, construction, and maintenance of the construction industry, and look into the digital transformation strategy of the construction industry in the future.

Systemic acquired resistance (SAR) is a form of systemic immunity that prevents secondary infections of distal uninfected parts of plants by related or unrelated pathogens. SAR is mediated by several SAR-inducing chemicals or mobile signals that accumulate after pathogen infection. Several chemicals that move systemically have already been identified as SAR-inducing factors, despite the fact that the early mobile signal remains unclear. These chemicals can be transported into either the apoplastic or symplastic compartments. Many of the chemicals associated with SAR remain unknown in terms of their transport routes. There is recent evidence that azelaic acid (AzA) and glycerol-3-phosphate (G3P) are transported via plasmodesmata (PD) channels, which regulate the symplastic route. In contrast, salicylic acid (SA) is preferentially transported from pathogen-infected to uninfected parts via the apoplast. The pH gradient and SA deprotonation lead to apoplastic accumulation of SA before it accumulates in the cytosol. Moreover, there is evidence that the mobility of SA over a long distance is crucial for SAR and that the partitioning of SA into the symplast and cuticles is controlled by transpiration. Further research has shown that a portion of the total SA in leaves is partitioned into cuticular waxes. The purpose of this review is to discuss the role of SAR-inducing chemicals and the regulation of transport in SAR.

물체 인식 및 추적 기술은 기계가 영상 정보를 기반으로 주변을 인지하고 정황을 파악하는 컴퓨터 비전 분야의 매우 중요한 연구 영역 중 하나이다. 현재까지 이러한 물체 인식/추적에 대한 다양한 연구들이 있어 왔고, 최근 증강현실에 대한 높은 관심을 바탕으로 증강현실을 위한 영상 정보 기반의 정확하고 정교한 추적 기술에 대한 관심 또한 매우 높아졌다. 본 논문에서는 텍스쳐가 없는 단색의 블록에 대해 증강현실을 실현하기 위한 물체 추적 방식을 제안한다. 제안하는 방식은 다수의 블록들을 조합하여 구성하고, 이 조합으로부터 추출한 특징점에 색상 정보 기반의 지역 서술자를 정의함으로써 사전에 정의된 서술자와 의 비교를 통해 물체를 추적하는 방식이다. 제안된 추적 방식은 사전에 기준이 되는 지역 서술자를 정의함에 있어서 기준 영상에 다양한 어파인 변환을 적용함으로써 카메라와 대상물과의 각도가 큰 입력 영상에 대해서도 추적에 실패하지 않는다. 실험을 통해 제안된 방식을 집 모양으로 구성한 블록 조합에 적용하여 3차원 가상 콘텐츠를 증강시켜 봄으로써 제안된 방식의 유용성을 확인하였다. 제안된 방식은 텍스쳐가 없는 환경에서 사용자의 상호작용으로 텍스쳐를 구성하고 이를 추적하는 방식으로 향후 아이들을 위한 교육 프로그램, 모바일 기기에서의 응용 프로그램 등으로 적용 가능하다.

정보통신기술(ICT)은 우리 일상생활에 너무나 깊숙이 스며들어 이제 정보통신기술 없이는 행정서비스, 경제활동, 사회참여, 문화활동 등을 향유하는데 많은 제약이 따르는 시대로 접어들었다. 정보통신기술에 접근하고 이용할 수 있는 사람과 그렇지 못한 사람들의 정보격차 (Digital Divide)가 경제격차와 사회문화적 격차를 유발하여 사회 불평등을 심화시키고 궁극적으로 사회통합을 저해할 가능성이 크다. 정보통신 접근성(ICT Accessibility)은 신체적, 인지적 제약으로 정보통신기기나 서비스에 접근하는데 어려움이 있는 장애인이나 고령자가 일반인과 차별 없이 정보통신의 유용성을 향유할 수 있도록 정보통신기기나 서비스에 대한 접근을 보장해 주는 것을 의미한다. 우리나라는 미국이나 유럽 등 선진국들에 비해 정보통신 접근성을 위한 법 제도적인 출발이 늦었지만, 최근 수년간 관련 법률의 제정, 정보통신 접근성 보장을 위한 지침 및 표준의 제정 등 다각적인 노력을 경주하여 빠른 속도로 선진국 수준을 향해 나아가고 있다. 지금까지 '한국형 웹 콘텐츠 접근성 지침 2.0', '금융자동화기기 접근성 지침' 등 12개에 이르는 표준을 제정한 바 있으며, 정보통신 보조기기의 개발 보급, 관련 전문인력 양성 및 교육 홍보 등을 통해 정보통신 접근성 수준 향상을 위한 노력을 지속해 왔다. 앞으로도 모바일 시대, 디지털 융합의 스마트 시대에 대응하여 다양한 정보통신기기 및 서비스에 대한 접근성 표준 제정, 관련 기술의 연구 등을 지속적으로 추진하여 모든 사람이 정보화의 혜택을 누리는 디지털 통합 (Digital Inclusion) 시대를 열어나가야 할 것이다.

The purpose of this paper is to plan and implement e-storytelling for improving children's creativity, which consists of e-storytelling, thinking questions, and character sticker canvas. Especially It makes children draw paintings feel easier by character sticker. This webapp shows the flash animation e-storytelling and gives the question to answer by painting with a fertile imagination on the canvas as transforming the character sticker. A user can input the title of painting and store it when finish the drawing. This is an educational tool which makes educatees think more and express their ideas through questions. Therefore, we can check how much children's imagination is changed and diversed by the stored paintings.

Purpose: The purpose of this study was to develop a sexual abuse prevention education program for elementary school students. Methods: Orem's Self-Care Theory (1995) and Seels & Richey's ADDIE model (1994) for developing learning materials were applied to develop this program Results: The development progress of the program consisted of 5 distinct phases: analysis, design, development, implementation, and evaluation. The contents was classified into 6 categories: the definition of sexual abuse, how to deal with sexual abuse, the situational reaction, areas with a high risk for sexual abuse, related organizations, and a wrap-up quiz. The app was easily accessible for elementary school students. Conclusion: A sexual abuse prevention program using a hybrid app may be an effective way to reach elementary students, and further research for children of various ages is required.

As mobile devices have rapidly spread to consumers, services with location information have been developed. The service that they provide related information by positioning automatically is referred to as 'Location-Based Service'. This paper suggests the ways that users instruct the students proper ethics in advance, after saving their moving course and offensive businesses in database, with 'Location-Based Service', by positioning their movements, especially the degree of breaking away from their course and the cases of their access to an offensive business and their stay in crime-prone areas, and comparing them to those in the database.

Purpose: This study was designed to evaluate a patient safety application in the prevention of adverse event among surgical patients. Seventy three surgical patients with thirty six of them using the patient safety application and the rest (N=37) were provided educational booklet. Further, the instrument would measure patients' right to know, knowledge about patient safety, and attitude toward patient safety. Methods: The patient safety application was developed by the ADDIE along with input from experts, patients and an extensive literature review. Data were collected from 7 September through 20 October 2015. Results: The experimental group had significantly higher scores in patients' right to know (t=2.01, p=.024), knowledge on patient safety (t=3.80, p<.001) and attitude toward patient safety (t=2.74, p=.004) than those of the control group. Conclusion: The patient safety application developed using Smartphone could be an effective tool enhancing patient involvement in preventing adverse events that may occur to patients. Further studies are recommended with diverse subjects with varying medical conditions.

It is hard to imagine teaching statistics without the help of technology. Technology is changing the way in which the content of introductory statistics is taught and the forms of textbook used. Almost all students carry mobile devices all the time that allows them to learn anytime and anywhere if we provide them with statistical electronic textbook. The use of smartphones for asking questions and finding answers in class, it can encourage students to engage more in lectures. This paper analyzes the data obtained using e-textbook in traditional classroom and discusses the future research direction of e-textbooks.
