If students are not aware of the information security, they easily let others know their information or they use others' information with no sense of guilt. The information security education is necessary to protect and prevent students from cyber crime. However, South Korea's information curriculum has no specific information security education course and it has led a school or teacher to teach contents of information ethics superficially. The purpose of this paper is to find the factors affecting the information security practice of the elementary school students. For an empirical analysis, questionnaire survey was conducted and the Partial Least Square(PLS) was used to analyze the research model. The analysis results show that the information ethics awareness and the information security awareness have a positive impact on the information security practice. The results of this study are expected to help choose the specific information security curriculum required for the information security practice of elementary school students.

This study establishes the scientific basis for the use of digital learning materials through the education-neurological research method and derives implications for education based on education-neurological understandings. The main findings of the education-neurological analysis of digital learning materials are as follows: First, various sensory stimuli go through multiple sensory neurons and deep sections of the upper sphere and make possible the cooperative processing of information. Second, indirect experience from digital learning materials helps students understand the learning contents vividly through the mirror neuron system. Third, positive emotions originating from digital learning materials promote functions of dopamine, the reticular activating system, frontal-striatal circuit, cerebrum cortex. Based on the findings, the study suggests the following educational implications. First of all, when selecting digital learning materials, teachers should consider expression forms, learning contents, the flow of classes, and the adverse effects of digital learning materials. Next, it is effective to utilize digital learning materials in the lecture for provoking curiosity and enjoyment, maintaining interest and effort, and reviewing what students learned.

The purpose of this study was to investigate the perceptions of the foodservice industry workers in regard to the use of seasonings and sweeteners in the restaurants. Questionnaires were distributed to 902 foodservice workers of various restaurants. Participants were questioned on their perceptions of both natural and artificial seasonings & sweeteners. Furthermore, they were asked to respond to questions regarding the need of public education and information about the use of seasonings and sweeteners, along with the demographic information. The results showed that 65.7% of respondents used both the artificial seasoning and artificial sweeteners, while 9.9% of respondents used only natural seasonings and sweeteners. The restaurant employees answered that they have tried to reduce the use of artificial seasonings and sweeteners(3.69/5 point). Some of the respondents reported that they have tried to increase the used of natural seasonings and sweeteners(3.54/5 point). There were significant differences in the respondents' perceptions and attitudes on the seasonings and sweeteners by the restaurant type(p<0.05). The respondents perceived the need for education on the safety of artificial seasonings and sweeteners(3.71/5point) and the production process of natural seasonings(3.75/5 point). There was no significant difference in the respondents' perceptions on the need for education of the seasonings and sweeteners by the restaurant type. The findings suggest that education regarding the use of artificial seasoning and artificial sweeteners, as well as cooking methods that use natural seasonings, is needed to reduce the use of artificial seasonings and sweeteners in restaurants.

The purpose of this study is to analyze the influence of digital textbook use for potential risk group of internet addiction and average group. For this, I selected two samples. One was a group to use digital textbook at school, the other was a group not to use that. Then each potential risk group of internet addiction were sort out in two groups by a test of internet addiction. I firstly compared a average user group and a potential risk group of internet addiction in group to use digital textbook. Also, I too did that in group not to use digital textbook. Then I analyzed the relevance of using digital textbook and internet addiction. As a result, I found that using digital textbook have not the relevance with internet addiction. But in this paper, I proposed a way to teach ICT ethical training before students use the digital textbook, because most of potential risk students of internet addiction tend to think they was influenced by digital textbook.

Current certification system use serial key for protect copyright of software and digital contents. But It is not efficient system, because It is not protect copyright through create virtual key or use public key. So we research on various cryptology for prevent illegal copy of serial key, but It is not enough protection of copyright that use software technology only. In this paper, we propose certification system using smart card for protect copyright of software and digital contents.

Design Up/Down converters which use Digital IF(Intermediate Frequency) techniques from the present paper, against hereupon performance the criticism. The reason which uses Digital IF techniques is configured of passive elements and the positions IF frequency domains are fixed and they do not use in the position one frequency but, the external fringe land of the board which comes to be configured with Digital IF without from the communication frequency domain which is various there to be a flexibility, the use was under possibility. Like this configuration compares in analog Heterodyne mode of existing and it has the performance upgrade which is excellent it shows a high flexibility.

This study analytically examined library anxiety that various users felt when they use public libraries, by measuring it on K-LAS. The findings show that the library anxiety is varied depending on users' age, gender, academic careers, usage purposes, frequency of use and size of libraries. It suggested the guidance and education about the use of libraries, environmental improvement based on the remodeling of libraries, wearing of nameplates written in big characters for identifying librarians and the education for users' understanding and the provision of device and equipment manuals according the levels of users' experiences, as measures for overcoming the library anxiety, enhancing usage satisfaction and activating usage.
