Software (SW) education is guided by the government to operate not only computer subject matter but also related subject matter. SW education is highlighted in the 2015 Revised Curriculum and Guide for Operating SW Education. SW education is related with science education. For example, education on algorithms employing SW and activities using sensors/output control can be an effective strategy for scientific inquiry. The method can also be applied in developing Computational Thinking (CT) in students. In this study, we designed lessons to solve everyday scientific problems using Educational Programming Language (EPL) SW and physical computing materials and applied them to high school students. We conducted surveys that were modified from questionnaires of Internet application capability and based on the standard of accomplishment of SW education as well as elements of CT to find out the change in perceptions on programming and CT of students. We also conducted a survey on students' attitude toward science learning after an SW inquiry activity. In the results, perceptions on programming and CT of students were improved through lessons using unplugged activity, EPL SW, and physical computing. In addition, scores for interest, self-directed learning ability, and task commitment were high.

As a result of climate change, mountain sediment disasters due to localized heavy rain and mountain development are occuring more frequently, thus, increasing social attention to and demand for soil erosion control projects. However, since 2011 Seoul Wumyeon Mountain landslide, the public is expressing increasing anxiety as well as negative perception regarding defective project results. Therefore, this study investigated promotional terms and information media related to soil erosion control projects according to the consumer in order to increase awareness of soil erosion control projects. In this study, the information consumers were divided into experts and the general public and conducted a survey related to promotional terms and media for communicating relevant information. In the result, the experts chose landslide prevention and recovery projects (41.8%) as an appropriate promotional term for soil erosion control projects. The general public, however, chose mountain sediment disaster prevention projects (32.5%) as the appropriate promotional term. However, the analysis showed that it would be necessary to develop an promotional term that can encompass the concept of 'disaster prevention' including forest and soil disaster as the word 'landslide' can suggest soil erosion control is limited to landslides only. In the survey regarding the media for communicating information related to soil erosion control projects according to the consumer type, the experts preferred radio and TV as media to communicate the relevant information, while, among the general public, the youths preferred social media such as Facebook and Twitter (22.22%) and adults radio and TV (34.07%), As for the most effective way to promote soil erosion control projects, the experts chose traditional promotinal media such as newspaper, radio, and TV (0.172) whereas the adults and youths preferred the internet and Facebook (0.089). It appears that using the preferred media for communicating information related to soil erosion control projects according to the consumer type will be effective way to promote soil erosion control projects.

Despite the growth in public concern about health information, the ratio of users who can search for accurate and reliable health information sources has been found to be quite low. Public libraries, as the best contact point to general users, must provide training programs for improving health literacy so that users will have the ability to search and analyze health information, judge the accuracy and reliability of resources, and make informed health-related decisions. This study developed a health information literacy education program suitable for Korean public library users. The effectiveness of the training was measured after administering the program, and necessary improvements were identified. As a result, this study found the education program had the following effects: improved public library users' familiarity with CHI-related terms, improved users' ability to find CHI-related information resources on the Internet, and significantly improved knowledge about health-related websites and information sources. In addition, users expressed interest in seminars on a variety of health information sources in the public library and asked that CHI-related education be included in the library's regular programming. However, this research represented the first time CHI-related education for public library users was performed in Korea, and therefore many limitations were present in the education instructor, the diversity of subjects, and the methodology. Development of more advanced CHI-related education programs for users is still required.

Methods : The participants were 453 parents who have kids age between 3 to 6 years old from day care center in Wonju and Chungju. The questionnaire consisted of 17 questions and the survey was conducted by self-entry method. This study analyzed 374 participants' questionnaires who agreed to the survey. Results : The percentages of children's health functional food intake experience were 82.9% and they usually bought products which contain lactic acid bacteria(55.6%). The reason for consuming health functional food was to strengthen the immune system and enhance the physical strength. Most of the participants purchased health functional food from pharmacy through inaccurate information such as the internet. The percentages of children's health functional food preference were 58.5% because it is easy to take. The percentages of children's herbal medicine preference were 41.7%. There are inconveniences of taking herbal medicine because of taste and smell(68.8%). Conclusions : Therefore, it is necessary to change the formulation of the herbal medicine and increase convenience for use of the herbal medicine to preschooler(3-6 years old).

Focusing on the individuals' structural positions and roles in the internet discussion network, this research explores whether and how the opinion leaders' network characteristics are associated with the message quality and interpersonal influence in terms of attention-drawing and response-generation, which prior studies often failed to fully explicate. Findings suggest that discussion participants with high message quality occupy more central positions in the discussion network, thus enjoy more attention and responses of other following participants. However, opinion leader's network centralities, which tap the structural positions and unique roles in the online discussion network, systematically mediate the effect of the message quality on interpersonal influence. Moreover, significant interaction between opinion perception and network centrality was found only on the majority opinion group, rendering the entire discussion structure toward more enclaved deliberation and group polarization. Taken together, the results imply that the influence of the online opinion leader can only be substantiated with participant's central positions in the discussion network, which has been ignored by the prior opinion leadership research.

In the era of the 4th industrial revolution, the development of information technology brought various benefits, but it also increased social interest in privacy issues. As the possibility of personal privacy violation by big data increases, academic discussion about privacy management has begun to be active. While the traditional view of privacy has been defined at various levels as the basic human rights, most of the recent research trends are mainly concerned only with the information privacy of online privacy protection. This limited discussion can distort the theoretical concept and the actual perception, making the academic and social consensus of the concept of privacy more difficult. In this study, we analyze the privacy concept that is exposed on the internet based on 12,000 news data of the portal site for the past one year and compare the difference between the theoretical concept and the socially accepted concept. This empirical approach is expected to provide an understanding of the changing concept of privacy and a research direction for the conceptualization of privacy for current situations.
