In mobile opportunistic networks (MONs), human-carried mobile devices such as PDAs and smartphones, with the capability of short range wireless communications, could form various intermittent contacts due to the mobility of humans, and then could use the contact opportunity to communicate with each other. The dynamic changes of the network topology are closely related to the human mobility patterns. In this paper, we propose a social motivation-aware mobility model for MONs, which explains the basic laws of human mobility from the psychological point of view. We analyze and model social motivations of human mobility mainly in terms of expectancy value theory and affiliation motivation. Furthermore, we introduce a new concept of geographic functional cells, which not only incorporates the influence of geographical constraints on human mobility but also simplifies the complicated configuration of simulation areas. Lastly, we validate our model by simulating three real scenarios and comparing it with reality traces and other synthetic traces. The simulation results show that our model has a better match in the performance evaluation when applying social-based forwarding protocols like BUBBULE.

This study analyzes mobile media-based writing aspects in terms of behavior induction under the premise that the digital media environment is built around mobile. The actual space where the digital writes are performed is a separate platform. The platform facilitates interaction by providing tools and rules to provide infra and participate in a variety of participants. In a mobile environment, writing is done through social platforms. In digital media, images are no longer content that supplements text. On the contrary, the tendency to use text as subtitles has been strengthened to enhance the message delivery power of video. The following are the aspects of digital writing based on the platform or application of mobile media. Second is the generalization of "textual extension." Third, the expansion of the 'visual style' of text is obvious. The affordance of mobile media is based on perceived affordance. However, mobile media users are not just aware of and understand the information provided by the media's interface. The active use of media based on the transformation of behavioral induction should be understood as the result of the accumulation of numerous experiences of interactions driven by iteration of performance induced by behavioral induction. The future research, therefore, should be conducted in the direction of analyzing new usage patterns of mobile media instead of staying on the behavioral induction based on understanding the perceived behavioral induction of users.

Environmental problems became bigger and widely known among all parts of the society in the last decade. The broad and sustainable study of the environment is the most basic and primary solution to the problems. For this reason, International Environmental Project Olympiad (INEPO) was organized in 1993. Many countries have participated in this organization. Therefore, the purpose of this study was to revitalize the environmental education and to realize the value of environmental education by making students aware of the environmental problems through the INEPO and Korean Environmental Olympiad (KEO). To achieve these goals, we conducted as follows First, we introduced aims, major contents and rules of the INEPO and grasped problems related to the applying method of students who want to participate in the INEPO in Korea. In addition, we introduced both results of domestic contest for participating in the 14th INEPO and of the 14th INEPO itself opened in 2006. Second, we analysed participants' themes according to project types such as environment-biology, environment-chemistry, environment-physics, environment-health and environment-social sciences from Previous INEPOs. Third, we had interviews with several participants to gather their thoughts on motivation and impression of participation, the reason of theme selection, and the method of environmental education in school, by visiting each booth of INEPO. Finally, we suggested sustainable methods of the KEO to revitalize environmental education, and proposed various methods to revitalize the environmental education through the KEO and INEPO in the primary and secondary schools.

Sleepiness is associated with many different conditions and, as a neglected topic, it can be the cause of serious psychological and social disadvantages. In the aspect of learning, additional problems may arise from poor progress in school caused by the effect of sleepiness on concentration, memory, and other cognitive functions. Narcolepsy is by no means the most common cause of excessive sleepiness. Nonetheless, it is not a rarity, especially in young people. The non-specific nature of early features of narcolepsy, combined with very limited awareness that the condition can start in various ways, leads to many misinterpretations. Misinterpretation of narcolepsy symptoms is not confined to the medical profession. Teachers may well be critical of a student with narcolepsy because of their perception of narcolepsy symptoms as laziness, poor motivation, or difficult behavior and dull learning ability. Inappropriate reactions by parents, teachers, and peers, based on misinterpretation of narcolepsy symptoms or the patient's reactions to them, make a difficult situation worse. Especially in Korea, where schooling is focused on college entrance examinations, the problem is very serious and intensified by inappropriate or delayed diagnosis and treatment. Therefore, psychiatrists should be aware that narcolepsy in young adolescents is not rare and that they need to be familiar with its clinical features in both its classic and less obvious forms. Narcolepsy should be suspected if a adolescent's excessive sleepiness can not be explained in other ways. Therefore, we report on two patients who portray the tendency of dull learning ability and are mistaken as idle students. We diagnosed narcolepsy through polysomnography and multiple sleep latency testing. We treated the students with methylphenidate and pemolin. The students showed improvement in learning ability and were able to adapt better to school.

The objective of this study is to investigate the intention to adopt smart wear, based on extended UTAUT model. We examined the effects of performance expectancy (PE), effort expectancy (EE), hedonic motivation (HE), social influence (SI), facilitating conditions (FC), and price value (PV) on the intended adoption of smart watch and smart shoes, respectively. In addition, moderating effects of gender, age, and innovation resistance were examined. An online survey was conducted, comprised of 2030 consumers who were aware of smart watch or smart shoes. In total, 393 responses were analyzed. About 50.4% were male, and 44.8% were in their 20's. An exploratory factor analysis generated five factors - PE & HM, EE, SI, FC, and PV- which were employed as independent variables in the multiple regression models. PE & HM, PV, and SI influenced on the intention to use both smart devices. FC showed the significant effect only on the intention to adopt the smart watch. In terms of gender differences, SI and PV were the important predictors of the intention to adopt the smart watch in the female group only. With respect to age difference, SI was very effective in explaining the intention of individuals in their 30's to adopt smart wear. Among the low innovation resistance group, SI was significant predictor, while PE & HE and PV were significant among the high resistance group. The findings provide useful information about the possibility of the adoption of smart wear, and new insight into market segmentation.

Lack of knowledge and digital skills is a threat to the information security of the state and society, so the formation and development of organizational culture of information security is extremely important to manage this threat. The purpose of the article is to assess the state of information security of the state and society. The research methodology is based on a quantitative statistical analysis of the information security culture according to the EU-27 2019. The theoretical basis of the study is the theory of defense motivation (PMT), which involves predicting the individual negative consequences of certain events and the desire to minimize them, which determines the motive for protection. The results show the passive behavior of EU citizens in ensuring information security, which is confirmed by the low level of participation in trainings for the development of digital skills and mastery of basic or above basic overall digital skills 56% of the EU population with a deviation of 16%. High risks to information security in the context of damage to information assets, including software and databases, have been identified. Passive behavior of the population also involves the use of standard identification procedures when using the Internet (login, password, SMS). At the same time, 69% of EU citizens are aware of methods of tracking Internet activity and access control capabilities (denial of permission to use personal data, access to geographical location, profile or content on social networking sites or shared online storage, site security checks). Phishing and illegal acquisition of personal data are the biggest threats to EU citizens. It have been identified problems related to information security: restrictions on the purchase of products, Internet banking, provision of personal information, communication, etc. The practical value of this research is the possibility of applying the results in the development of programs of education, training and public awareness of security issues.

해킹은 현대의 지식기반 사회에 심각한 문제를 야기하고 있다. 해킹으로 인한 피해 규모와 피해 금액 또한 꾸준히 증가하고 있다. 따라서 현재까지 해커 또는 해킹과 관련한 많은 연구들이 진행되어 왔다. 기존 연구에 의하면 해커들은 재미와 같은 내재적 동기에 의해 해킹 기술을 습득하며, 주로 해킹 커뮤니티에서 기술을 습득하는 것으로 알려져 왔다. 또한 최근에는 재미나 흥미 등 내재적 동기는 물론 금전적 보상 등과 같은 외재적 동기도 증가하고 있다고 한다. 그러나 현재까지의 관련 연구들은 표본 수집의 한계로 인해 정성적 연구에 치우쳐 왔다. 따라서 본 연구는 기존 연구의 한계를 극복하기 위해 해킹 커뮤니티에 소속된 멤버들을 대상으로 계획된 행동이론을 기반으로 한 정량적 연구를 진행했으며, 동기적, 사회적 그리고 환경적 요인이 해커의 학습에 미치는 영향 요인을 규명하였다. 본 연구는 보안 및 해킹 기술을 습득하기 위해 결성된 대학정보보호연합 동아리를 대상으로 2015년 5월에 약 2주 간 설문을 진행했다. 회원 전체에게 이메일을 보내 응답한 215개의 설문지를 바탕으로 연구가설을 검증하고 분석했다. 연구 결과, 해킹 기술 습득자들은 해킹 기술 습득이 사회적으로 비윤리적으로 인식되고 있다는 것을 스스로 인지하고 있었으며, 재미나 흥미와 같은 내재적 동기 및 타인의 인정을 추구하는 외재적 동기 모두 학습 태도에 영향을 주었고, 온라인 해킹 커뮤니티의 접근성과 정보 품질과 같은 환경적 특성이 해킹 기술 습득에 영향을 주는 것으로 나타났다. 본 연구는 학문적으로 해킹은 사회적으로 부정적으로 인식된다는 것을 밝혀내어 비윤리적 연구의 주관적 규범의 방향성에 대한 논의를 확장시켰고, 동기 요인들이 해킹 기술 습득 태도에 영향을 미친다는 점을 실증했다. 또한, 해킹 커뮤니티의 특성이 지각된 행동통제의 선행 요건임을 밝혀내어 계획된 행동이론의 적용 범위를 확장했다. 또한, 실무적으로 해커들을 윤리적 해커(정보보호전문가)로 만들기 위한 윤리 교육의 필요성과 해킹 방지를 위한 처벌의 강화 및 과징금 부과 등이 해커의 행동 변화에 영향을 줄 수 있음을 제시했다.
