  • In recent years, in the domestic industry, personal damage has occurred due to sensor malfunction and the emission of harmful gases. But there is a limit to the reliability verification of sensor data because the evaluation of environmental sensors is focused on durability and risk tests. This platform designed a sensor board that measures 10 major substances and a performance verification system for each sensor. In addition, the data collected by the sensor board was transferred to the server for data reliability evaluation and verification using LoRa communication, and a prototype of the sensor data platform was produced to monitor the transferred data. And the collected data is analyzed and predicted by using machine learning techniques.

  • An irrigation monitoring system is an efficient approach to save water and to provide effective irrigation scheduling for rice cultivation in desert soils. This research aimed to design, fabricate, and evaluate the basic performance of an irrigation monitoring system based on information and communication technology (ICT) for rice cultivation under drip and micro-sprinkler irrigation in desert soils using a Raspberry Pi. A data acquisition system was installed and tested inside a rice cultivating net house at the United Arab Emirates University, Al-Foah, Al-Ain. The Raspberry Pi operating system was used to control the irrigation and to monitor the soil water content, ambient temperature, humidity, and light intensity inside the net house. Soil water content sensors were placed in the desert soil at depths of 10, 20, 30, 40, and 50 cm. A sensor-based automatic irrigation logic circuit was used to control the actuators and to manage the crop irrigation operations depending on the soil water content requirements. A developed webserver was used to store the sensor data and update the actuator status by communicating via the Pi-embedded Wi-Fi network. The maximum and minimum average soil water contents, ambient temperatures, humidity levels, and light intensity values were monitored as 33.91 ± 2 to 26.95 ± 1%, 45 ± 3 to 24 ± 3℃, 58 ± 2 to 50 ± 4%, and 7160-90 lx, respectively, during the experimental period. The ICT-based monitoring system ensured precise irrigation scheduling and better performance to provide an adequate water supply and information about the ambient environment.

  • The government is mapping out R&D innovation measures aimed at improving the qualitative level of the performance of national R&D projects that are supported by grants or public funds. This paper proposes ways of making improvements in technology planning, project assessment, performance management, and results evaluation in order to boost the efficiency of the country's promotion of ICT R&D projects, as well as to upgrade the processes involved with its technological innovation system at each of the commercialization stages of its R&D projects. According to our experts' in-depth survey and interview, it has been found that technology planning is the most important phase in the full cycle-based technological innovation system and that the promotion of a combination of top-down and bottom-up approaches is the most reasonable. This paper also suggests it is necessary to secure a process for exploring technological opportunities as the preparatory phase for technology planning, and that it is desirable to reflect the technology demand map associated with the technology road map. Currently, R&D projects are divided into policy designation, designation contest, and free contest. To minimize the inefficiency associated with indiscriminate competition, this paper proposes the introduction of a general contest system in order to change the project assessment system into one based on the results of the competition in each category(e.g. firms, universities, research institutions, etc.).

  • In this paper, we propose an autonomous driving system using an end-to-end model to improve lane departure and misrecognition of traffic lights in a vision sensor-based system. End-to-end learning can be extended to a variety of environmental conditions. Driving data is collected using a model car based on a vision sensor. Using the collected data, it is composed of existing data and data with outlayers removed. A class was formed with camera image data as input data and speed and steering data as output data, and data learning was performed using an end-to-end model. The reliability of the trained model was verified. Apply the learned end-to-end model to the model car to predict the steering angle with image data. As a result of the learning of the model car, it can be seen that the model with the outlayer removed is improved than the existing model.

  • The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.

  • Both employee satisfaction and loyalty play an important role in increasing the business performances of organizations in the service industry. However, the influence of TQM practices on employee satisfaction and employee loyalty has not been examined in the ICT service supply chain. This study aimed to investigate the impact of five total quality management (TQM) practices on employee satisfaction and employee loyalty in Korean ICT customer service and retail distribution organizations. Based on an empirical study of 578 respondents in a Korean ICT service company, the study examined the hypothesized relationships among TQM practices, employee satisfaction, and employee loyalty. Using structural equations modeling, it is found that TQM practices are significantly related to employee satisfaction, whereas the latter in turn influences employee loyalty. The results of analysis suggest that the ICT customer service and retail distribution organizations should concentrate on enhancing employee satisfaction of their TQM practices and creating a people-satisfied job environment.

  • This article consists of 3 parts. Part I is multi stakeholder approach on Internet governance system. Part II is analysis of the Korean Internet governance system. In this part, I explain relevant laws in Korea, including Korean Internet Address Resources Act. Part III is my suggestion on Korean Internet governance system using a multi stakeholder approach. First of all, the keyword of the Internet governance system is decision making process: that is, consensus based versus top-down approach. Then who are major players in Internet governance in national level? Government, or Private sectors such as business and civil society. Korean legal system for Internet governance shows a top-down decision making process. Major players are the government (that is, Ministry of Science, ICT and Future Planning) and KISA affiliated with the government. Other players include Internet Address Policy Committee, Korea Internet Governance Alliance, and NGOs. The key statute for Internet governance in Korea is Internet Address Resources Act of 2004. Articles 3 and 5 require the Ministry of Science, ICT and Future Planning to take a proactive role in Internet governance. The government shall consult with the Internet Address Policy Deliberation Committee for Internet governance. Yet this Committee is established under the control of the Ministry of Science, ICT and Future Planning. All members of this Committee are also commissioned or nominated by the Chairman of the Ministry. Meanwhile, there are also non-official organizations, including Sub-committee on Address & Infrastructure of Korea Internet Governance Alliance. I suggest to reform decision making process of Korean Internet governance system based on BOTTOM-UP process for CONSENSUS BASED DECISION. My suggested system includes the following: (1) The government hands over a major role in Internet governance to INDEPENDENT Internet policy organization. And the government participates in such organization as ONE of the players. (2) Nomination of this committee member must be bottom-up process for a genuine multi-stakeholder model including civil society, commercial organization, end-users and experts. (3) The government should establish plan for supporting the private sector's international activity on the long-term basis.

  • The purpose of this study is to propose a Busan tourism industry in which the 2016 OECD Tourism policy and ICT convergence platform are applied. OECD proposed 3 policies to promote the tourism industry: First, to maintain the competitiveness of the tourism industry as well as improve its efficiency and sustainability, second, to establish a seamless traffic system, and third, to build a response to the sharing economy. Centering on the OECD's three policies, we propose the developmental possibilities of tourism in Busan. At the same time, we suggest the necessity to build an ICT convergence platform that will help foster the industry. In building an ICT convergence platform, we especially focus on the necessity of: 1. Sharing and creating experience-based interactive contents on the software side, and 2. Developing high quality user experience (UX) and providing a data analysis-based customized service on the hardware side. In addition, we insist on the establishment of the Tourism Promotion Agency for the continuous performance and management of Busan tourism industry. The study ultimately suggests that the construction of ICT convergence platform based on OECD tourism policy can result in the expected outcomes of high effects with low cost for both consumers and suppliers related to the tourism industry.
