The socio-cultural and economic changes following the Fourth Revolution are driving the growth of the food tech industry. Korea's food tech industry is still focused on delivery apps and the smart farms, robot market including artificial intelligence are in its infancy. In the United States, alternative meat companies are already included in unicorn companies, while Korea, the fourth largest importer of beef, lacks alternative meat development. France, Europe's largest agricultural country, is focusing on Agtech. China has developed the Internet and online e-commerce market with the world's number one population. Korea also needs to change regulations that focus on the past industry and various food tech industries should be developed through political and business-driven research and investment.

In this study, a dual structured pipe for a preventive monitoring on a accident damage, a smartphone app program for a survey and a construction data collection and a server program for a real-time monitoring were developed. A pilot system was installed in the test field to analyze effects of a system developed in this study. The data for a damage prevention was detected by the attached sensors on the pipe. Exclusion was tested by the pressure sensors to be installed at regular intervals. The app and server programs was enabled to the real-time data collection and real-time monitoring linked by VRS survey equipments and a smartphone.

As the number of malicious Android applications increases rapidly, many automatic analysis systems are proposed. Hoping to trigger as many malicious behaviors as possible, the automatic analysis systems are adopting random touch generation modules. In this paper, we propose how to differentiate real human touches and randomly generated touches. Through experiments, we figured out that the distance between two consecutive human touches is shorter than that of random generation module. Also we found that the touch speed of human is also limited. In addition, humans rarely touch the outer area of smartphone screen. By using statistics of human smartphone touch, we developed an algorithm to differentiate between human touches and randomly generated touches. We hope this research will help enhance automatic Android app analysis systems.

With the continuous increase of the senior population, it is necessary to introduce the 4th industrial revolution applied technology into the health and welfare field. In addition, a senior emergency management system centered on Nono Care is established due to the shortage of young people, which requires strategization of a welfare delivery system in which senior colleagues notify emergency relief facilities directly in case of an emergency. In this paper, senior emergency management system is designed to collect and analyze individual activities and inactivity information through senior self-learning through smartphone app and to predict emergency situations with voice and image registration information through smartphone app menu.

This study presents the educational utility of blended learning by analyzing the effectiveness of learning after class by blending team project learning and smart device app-based learning methods. Qualitative analysis and survey analysis were conducted and the results were as follows. First, team project activities based on task resolution were conducted freely through detailed activities such as sharing roles, planning meetings, and coordinating opinions. Team activities were carried out with respect and consideration, team member bonding, and a sense of responsibility. Second, the smart device app is recognized as a medium for work and communication, and fast feedback has been made, making it highly impactful on classroom activities. Third, in terms of learning satisfaction, most learners showed an interest in the course and were satisfied with the project results. The smart device app was used as a learning and communication medium for personal and team activities and was analyzed as a blended method applicable to classes that conduct practical activities as an efficient tool to further activate project activities.

Purpose: The purpose of the study was to develop a smartphone app-based emergency coping education program to improve caregivers' emergency coping abilities and identify the program's effect on knowledge, attitudes and confidence in first aid. Methods: The study was conducted with 80 caregivers in elderly care facilities and home care centers. A total of 40 participants were assigned to experimental and control groups of caregivers working in elderly care facilities and home care centers using a nonequivalent control group pretest-posttest design. The data were analyzed using the 𝝌²-test and the independent t-test with the SPSS 25.0 program. Results: The experimental group had higher scores and a statistically significant increase in knowledge(t=6.26, p<.001), attitude(t=5.25, p<.001), confidence(t=3.38, p<.001) and emergency coping abilities(t=8.83, p<.001) was observed in comparison to the control group. Conclusion: The smartphone app-based emergency coping education program has proven the effectiveness of education by improving the ability of caregivers to cope with emergencies, suggesting the need to expand and apply it to more caregivers. In order to maximize the learning effect, app-based educational content should be developed in more diverse areas along with follow-up research with various education contents.

We study the level on the knowledge, attitudes, and practice of primary school (grades 3-6 students ) for the safe use of smart devices, and identify student status for the safe use of smart devices, and suggests ways of appropriate data collection, analyzing of data. Through this research, for the safe use of smart devices in education showed that the effect is very insignificant and the knowledge and practice of smart devices are widely recognized. We will suggests the suitable education contents for the smart devices safe use for primary school students. These education will be made up of 'smart devices safety using' and we will expect that primary students will be able to cultivate the 'smart devices security awareness'.

본 논문은 스마트 TV 플랫폼에서 실행되는 앱이 TV 에 특화된 기능을 수행하기 위해서 필요한 스마트 TV확장 API 의 정의와 그 구현에 대한 내용을 소개한다. 2013 년 3 월 TTA 에서 제정된 "HTML5 기반 스마트 TV 플랫폼" 표준은 스마트 TV 용으로 제작된 하나의 앱이 다양한 TV 수신기에서 동일한 사용자 경험(UX)을 바탕으로 실행될 수 있는 TV 플랫폼 표준이며, 이는 HTML5 를 포함하는 최신 W3C 기술 규격을 기반으로 하고 있다. 본 논문에서는 표준에 기술된 사항 중 채널과 프로그램과 같이 TV 에 특화된 기능으로 W3C 에 규격범위에 포함되지 않아 새롭게 정의된 확장 API 의 구조 및 기능에 대해서 설명한다. 확장 API 는 앱, 방송, 수신기의 세가지 항목으로 분류되어 상세한 인터페이스 기능을 정의하고 있으며 스마트 TV 플랫폼의 window 객체 아래에 전역 속성으로 계층 구조를 이루도록 설계되었다. 스마트 TV 앱은 이러한 확장 API 를 호출하여 방송과 연계된 다양한 서비스를 실현할 수 있다. 또한 본 논문은 확장 API 의 유효성 검증을 위하여 표준을 준수하여 구현된 수신기 플랫폼과 앱의 구현과 동작 사례를 제시하고 있으며, 유럽의 스마트 TV 방송 규격인 HbbTV 와의 비교를 통해서 API 의 장단점과 지원 범위를 확인하고 개선 방향을 모색한다.

Humanities knowledge makes the learners overcome the boundaries of study and can be applied variously by means of contents for study. This paper suggests application contents plans designed as the learning tools for blended learning, which can be sure of the possibility to the extension of other fields. Literary education with application contents has effects followings: First, smart device based on the web under the ubiquitous circumstances has the information system like the neuron's. So the application selects the necessary information and makes the contents for infusion into the education. Also it provides with more abundant and extended information system. With this approach, learners are able to get further literary knowledge and promote the ability for tapping them for new knowledge as well. Lastly, literature applied to the class with web contents is based on the foundation that creates new knowledge necessary for culture, arts, and so on. As a result, the education using web contents achieves the boundless of study, which is the final goal of the blended learning.
