  • Software integration becomes very important in these days. Since the 4th industrial revolution has begun and influences its heavy effects on our daily life, software education has been introduced in the 2015 national revised curriculum. The purpose of this study is to verify the effects of a mobile web application for the elementary algorithm class based on STEAM on the problem solving process of elementary school students. To do so, in this study we constructed an algorithm learning contents based on STEAM for new software education and developed a mobile web application for flipped learning to improve their problem solving ability. Further, an experimental group and a controlled group are selected respectively from the 5th grade elementary school students. Then, a new flipped learning class using our mobile materials was applied to the experimental group while a traditional lecture class using the activity papers was applied to the controlled group. Finally the paired samples t-tests were carried out. As a result, we found that there was a statistically significant difference in problem solving process between the two groups. Based on our experimental research and the results of statistical analysis, the mobile web application class based on STEAM turned out to be effective in improving the problem solving ability of elementary school students.

  • In the vortex of change, commonly referred to as the Fourth Industrial Revolution, Korea has a national task of changing the paradigm of economic growth from a chase-type economic structure to a leading one. The era has come when all resources of the country, as well as the government and businesses, must join in innovation and growth in order to maintain the pace of sustained economic development, and significantly advanced countries are stimulating members' innovation activities with various policies and systems as they enter the 21st century. South Korea is also making efforts to create an open creative space referred to as Makerspace or Fab Lab, to create an innovative voluntary environment for its citizens. This study explored factors that Makerspace, which is proliferating in Korea, should consider to secure development and sustainability as an innovation (start-up) space. Through prior research, openness and expertise were derived from the characteristics of Makerspace, and expert interviews confirmed that the capabilities lacking in Makerspace and the capabilities to be secured in the future are openness and professionalism. Also, specific components of openness and professionalism were presented through prior research, and implications for each subject's Makerspace were presented, such as openness, professionalism, and commercialization.

  • The reliability of the results of LCC analysis is determined by accurate analytical procedures and energy data from which the uncertainty is removed. Until now, systems that can automatically measure these energy data and produce databases have not been commercialized. Therefore this paper proposes a concept model of an S-LCC platform that can automatically collect and analyze electric energy consumption data of equipment systems using the IOT, which is the core tool in the Fourth Industrial Revolution and operates the equipment system efficiently using the analyzed results. The proposed concept model was developed by the convergence of existing BLCS and IOT and was comprised of five modules: Facility Control Module, LCC Analysis Module, Energy Consumption Control Module, Efficiency Analysis Module, and Maintenance Standard Reestablishment Module. Using the results of LCC analysis deduced from this system, the deterioration condition of an equipment system can be identified in real-time. The results can be used as the baseline data to re-establish standards for the maintenance factor, replacement frequency, and lifetime of existing equipment, and establish new maintenance standards for new equipment. If the S-LCC platform is established, it would increase the reliability of LCC analysis, reduce the labor force for entering data and improve accuracy, and would also change disregarded data into big data with high potential.

  • The purpose of this study is to provide fundamental data for robot-based education at home by analyzing the factors affecting the recognition and technology acceptance attitudes of mothers with young children. For this purpose, a questionnaire survey was administered to 319 mothers with young children in Seoul and Gyeonggi Province, and one-way ANOVA, chi-square, correlation analysis, and regression analysis were conducted for statistical verification. As a result, there was a significant difference in the robot-based education at home of mothers to child according to their final educational background. Mothers' acceptance intention, perceived ease of use, perceived usefulness, social influence of robot application and personal innovation were all positively correlated. The factors that affect intention of acceptance were perceived ease of use and perceived usefulness of robot application. Conclusively, mothers with young children use robot-based education at home when it is more convenient to use and has educational effects more than the personal innovation or social influence. These study results are meaningful ahead of the 4th industrial revolution in that we provided basic data for the correct direction of robot-based education to young children at home.

  • In order to cultivate the talents needed in the 4th industrial revolution era, it is necessary to select gifted students and train them systematically. The affective characteristics of the gifted are self-concept, personality, sociality, motivation, morality, attitude and interest, and these are important factors that affect science achievement. In particular, computer scientific attitude is an important variable affecting computer science achievement. This study developed a computer scientific attitude test based on TOSRA developed by Fraser to measure the affective characteristics of information-gifted students. The computer scientific attitude test is composed of 7 areas: social implications of computer science, attitude to computer scientific inquiry, adoption of computer scientific attitudes, adoption of computer scientific attitudes, leisure interest in computer science, career interest in computer science, and normality of computer scientists. The relationship between computer scientific attitude and academic achievement of gifted students was analyzed using the developed test. To determine find out whether computer scientific attitude significantly predicts academic achievement, the results of a regression analysis showed that t = 2.543 and p = 0.025, indicating that the average of computer science attitude significantly predicted academic achievement.

  • This paper is on the implementation of a system for automatically monitoring window farm hydroponics based on Arduino (utilizing Arduino's open source code) emerging as the icon of the Fourth Industrial Revolution. A window farm, which means window-type hydroponics, is offered as an alternative to fulfill the desires of people who want to grow plants aside from the busy daily life in the city. The system proposed in this paper was developed to automatically monitor a window farm hydroponics cultivation environment using the Arduino UNO board, a four-charmel motor shield, temperature and humidity sensors, illumination sensors, and a real-time clock module. Modules for hydroponics have been developed in various forms, but power consumption is high because most of them use general power and motors. Since it is not a system that is monitored automatically, there is a disadvantage in that an administrator always has to manage its operational state. The system is equipped with a water supply that is most suitable for a plant growth environment by utilizing temperature, humidity, and light sensors, which function as Internet of Things sensors. In addition, the real-time clock module can be used to provide a more appropriate water supply. The system was implemented with sketch code in a Linux environment using Raspberry Pi 3 and Arduino UNO.

  • As Korean traditional peasant farming has come to a commercialization since 1970s, the spatial structure of Korean agriculture also has been gradually restructured by principle of not subsistance but economy. This epochal transformation of agriculture and its spatial structure in Korea are comparable with the first agricultural revolution in Europe. Facing this turning point, it is essential to redefine the nature and significance of agricultural geography in Korea through the review of the outcomes of about 200 studies published since 1950s in Korea of which twelve is concerned with locational analysis. The purpose of this study is to review the trend and characteristics of location studies on Korean agriculture. Major findings are as follows: (1) Since 1950s the location studies of agriculture recorded only 12 papers which occupy no more than 6% of studies of agricultural geography in Korea. This fewness suggests that the location study of agriculture in Korea is yet at the stage of beginning. (2) In spite of the fewness the studies, carried out mainly in 1980s, contributed considerably to clarify the locational characteristics of Korean agriculture especially in the spatial variations of crops, dairy farming and cropping system, the impacts of agricultural labors, the location strategy of mountain agriculture, and the responses of farmers to hazard. (3) In approach and methodology, two thirds of the studies has taken traditional empiricist view and other, positivist. And most studies adopted classic and neo-classic locational theories as their theoretical base in description and explanation. In degree of development, the location studies of agriculture in Korea seems to be about 20 years delayed compared to that of the advanced countries in terms of approach and methodology. (4) Such tradition of the location studies reflects not only the conservative nature of agricultural geography of Korea but also the early stage of capitalism of Korean agriculture.

  • Today's sports, by themselves, express a wide variety of phenomena and reproduce or imply complex social symbols. The definition of sports being transformed in combination with ideology, which has become a central issue in each era, has become more diverse in recent years. Recently, with the 4th Industrial Revolution leading the social phenomenon, sports culture is producing a new phenomenon. In this era, we need the study in the question of how to understand and interpret sports culture is the right approach. The struggle for survival in each discipline was expressed as a reinterpretation of sports culture. This is to answer questions about how sports culture is consumed, spread and reinterpreted. The purpose of this study is to find out the direction and directing point of sports culture. Based on such problem recognition, five types of answers to what sports culture consumes were presented. Based on this, the fairness related to school sports, sports society-club(sports clubs), sports events, sports media, and sports was suggested as a medium for the spread of sports culture. We are accepting and transforming numerous scientific civilizations to improve sports culture and to promote consumers. However, there is a pity not to define such a thing. Efforts at a more fundamental level, such as cultural regulation and fundamental directions, need to be discussed. The framework of reinterpretation of sports culture should be constantly looking for directions and answers about what to do, not just the level of interpretation.

  • Purpose - Recently, the fourth industrial revolution is rapidly progressing, and the central government-led innovation system is not able to flexibly cope with changes in science and the economy and society. To solve these problems, it is necessary for local governments, which can easily identify and flexibly respond to local sites, to become self-centered and ready to respond more quickly to massive changes. Through this research, this study investigated the awareness of the elements of Jeonnam Province's capabilities in the field of science and technology policy, the importance of R&D, and how network cooperation among the base institutions might affect performance. Research design, data, and methodology - In fact, the data used in this study only 115 people were polled, excluding five who did not respond to the necessary variables. The methods of the survey were sampled, and the means of the survey were investigated via a self-contained electronic file (e-mail). Statistical analysis, including hypothesis verification, was performed by SPSS 19. The regression analysis was used. Results - All factors significantly affect performance by dividing them into five sub-fields: R&D strategic establishment, R&D demand survey, R&D planning, R&D evaluation, and R&D project management. These results suggest the importance and need for local scientific technology policy capabilities. Besides, it was confirmed that the relationship between regional science and technology policy capabilities and performance was moderated by the recognition of the importance of science technology and network cooperation among the core organizations. Conclusions - As a result, independent variables regarding the capabilities of each scientific technology policy were found to be statistically significant and have a significant effect on performance. Second, the regression analysis has shown the moderation effects of R&D importance awareness between the capabilities of science and technology policies and their performance. On the other hand, a regression analysis showing that the capabilities of science and technology policies and network cooperation between the base regions were not significant, indicating that there is no effect of moderation of network cooperation between the base regions between the capabilities of science and technology policies and performance.
