With development of computer engineering and the examination theories, new techniques to use computers in making or administrating examinations had been studied and developed. Recently, studies on web-based testing are in progress with development of Internet and information and communication technology. However, as compared with development of these technical aspects, studies on the user legibility to provide learners with comfortable environment for the evaluation have been insufficient in fact. In the web-based testing, user legibility decreases the anxiety of examinees in the examination and plays an important role in measuring their competence exactly. In this study, we tried to provide the optimum web-based evaluation interface by obtaining information through a questionnaire for primary-school students. We think that principles suggested in this study can give a great help in making the web-based evaluation screen in future. Besides, studies on more various fields including making individual questions, instructing sentences and layout of multimedia factors as well as the principles mentioned in this study should be performed.

Recent studies have offered ambiguous definitions of smart ports. These include smart ports being the only way that fully integrated ports can survive (Deloitte 2017) or ports that have a design based on Internet-of-Things technology to minimize waste of urban space and resources (Port Technology 2016). In addition, many port authorities are creating smart port strategies and have held research seminars focused on smart ports. This study sheds light on the following questions: Why do we need smart ports? Why should all ports be smart ports? Why are overseas advanced ports promoting smartization as soon as possible? What does the future look like for smart ports? Therefore, in this study, we explored the concept of smart ports based on previous research and examined the trends in smart port policies in the Netherlands, Germany, the UK, Italy, and Singapore. Finally, this study proposes useful policies for smart ports and also discusses policy directions that could make our ports truly smart ports.

This study investigated the demand of nutrition education programs among preschooler's parents. Focus group interview was conducted four times with 29 parents of preschool children. Most subjects appeared to have interest in nutrition education; 'very interested' (58.6%), 'somewhat interested' (20.7%). Sources of nutrition information were 'internet' (35.1%), 'books' (21.6%), 'newspaper or magazines' (13.5%), 'family or relatives' (13.5%), 'media' (8.1%), 'preschool' (5.4%) and 'hospital or public health center' (2.7%) in order. The most frequently mentioned health problems related to dietary behavior were atopy and obesity. Major concerns for children's dietary behavior was picky eating habits, and having questions for how to deal with this problem. Most subjects had trouble with obtaining an adequate amount of dietary supplements for their children. Nutrition education for parents about food labeling and information on processed foods was in demand. Preferred methods of nutrition education for children were playing games with stickers, gardening vegetables, and participating in cooking. Attitudes toward computer-assisted education materials, one of the methods of nutrition education, appeared to be ambivalent. Some preschool parents showed negative attitudes towards exposing their children to electronic devices at an early age, whereas others showed positive attitudes. Subjects were interested in meal-planning and ways to balance nutrients for their child. Parents preferred attending professional lectures to receive reading materials or searching websites as an adult nutrition education method. Results of this study have implications on providing basic information for developing nutrition education programs for preschoolers and their parents. Future research should focus on developing nutrition education programs for both preschools and the home.

Food and Agriculture Organization (FAO) and many countries make an effort to conserve and utilization of animal genetic resources to prepare for our unpredictable future. In order to protect the customer and the producer from the animal diseases and unjust distribution, many country seek to appropriate solution. Among the solutions, RFID technology can be used as a basic technology, since this technology can be applied in the conservancy and utilization of animal genetic resources, object management for improved animal and traceability of animal's distribution flow. There are two main issues in making the efficient RFID environment. The first issue is the standardization of code system for object identification. International Organization for Standard (ISO) published the standard which regulates RFID of animal (ISO 11784 and ISO 11785). Based on these standards, many countries have tried to establish their national standard. In Korea, National Institute of Animal Science (NIAS) playa main role in establishing the standard of object identification code based on ISO 11784. Even though the standard format of object's identification is well established, the RFID system may not be operated well without the standardization of RFID network and related equipment. In Korea, National Internet Development Agency of Korea (NIDA) has proposed the RFID Network at 2006, which can be applied in the different kind of system at each phase. But, the implementation case of this RFID Network does not reported yet, since many company or agency who introduce RFID technology, implemented as an isolated individual system. In our study, we show that RFID network can be utilized for any kind of system at each phase, and propose the improvement point in order to be widely used.

Currently, the commercialization of the $5^{th}$ Generation (5G) service is becoming more prevalent in domestic communication network technology. This has reduced communication delay time and enabled large-capacity data transmission and video streaming services in real-time. In order to keep pace with these developments, K-water has introduced a smart process control system in water purification plants to monitor the status of the water purification process. However, since wireless networks are based on the public Long Term Evolution (LTE) network, communication delay time remains high, and high-resolution video services are limited. This is because communication networks still have a closed structure due to expense and security issues. Therefore, with 5G in its current form, it is very difficult to accommodate future services without improving the infrastructure of its communication networks. In recognition of these problems, this study implemented the authentication and management function of wireless networks on a wired network management system in the K-water Bansong water purification plant. The results confirmed that wired Local Area Network (LAN) services give a higher security performance than an expensive commercial wireless LAN system. This was achieved by using an Internet Protocol (IP) address management system of wired networks and the packet filtering function of the Layer2 (L2) switch. This study also confirmed that it is possible to create a wireless LAN service that is 3.7 times faster than the existing LTE communication network.

The arrival and expansion of the Internet has extended consumers' options and has provided consumers' opportunities to offer their own consumption. Through a laboratory experiment, we investigated questions: 1) do consumers trust the accuracy of reviews posted by anonymous reviewers or experts and 2) do readers trust negative and positive reviews equally? The messages were created as a form of 4 scenarios for this study. The statistical analysis was conducted using SPSS Win(v.16.0) for descriptive analysis, and t-test. Our results from a 2(positive reviews vs. negative reviews)*2(consumer vs. expert) experiment design showed that there was a significant difference between consumers' review and experts' one in restaurant visit intention(p<.001) and information credibility(p<.001). Also, between positive review and negative one, significant difference was found in restaurant visit intention(p<.001) and information credibility(p<.01). Other results, limitations and future research directions were also discussed.
