블루투스 기술은 이동 단말, 개인용 컴퓨터 및 주변기기, 정보가전 등에 다양하게 적용되어 왔다. 이러한 적용 영역들 중에서도 원래 블루투스 기술의 최대 관심인 휴대폰에의 적용이 가장 비약적으로 이루어져, 현재는 무선 헤드셋 및 전화접속 네트워킹 등의 응용에 사용되고 있다. 하지만 현재의 블루투스 기술은 무선 헤드셋 영역에 집중되어 있고 다양한 소프트웨어 응용 및 적용 사례가 미약하다. 본 논문에서는 블루투스 노드와 블루투스 AP(Access Point)를 이용하여 영화관, 기차역, 은행, 관공서 등의 다양한 장소의 키오스크 서버(Kiosk Server)에 원격으로 접속하여 모바일 단말기기는 사용자의 입력과 출력만을 담당하여 키오스크 서버에 전달되고 키오스크 서버는 전달된 데이터를 처리하여 사용자에게 전달하는 Profile의 프레임워크를 설계하여 차후 구현을 목표로 한다.

The purpose of this study is to verify the moderating effect of mobile divide on the relationship between individual characteristics and the use outcomes of smart device. Data was collected through a survey for periods from May 12, 2017, to May 17, 2017. As a result of multiple regression analysis based on collected data, self-efficacy, information seeking desire and culture capital have a positive effect on the use outcomes of smart device. To examine the moderating effect of mobile divide, we conducted a hierarchical regression analysis by calculating the interaction variables of the independent variable and the mobile literacy. As a result of the analysis, it was found that mobile literacy has negative moderating effect between self-efficacy and the use outcomes of smart device. The results of this study can be interpreted as the higher the self-efficacy and information desire for ICT technology users are. In addition, it can be interpreted that the smart device is convenient in the cultural activities of individuals, and therefore, it is highly utilized. Next, among those who have excellent mobile use ability, those who have high confidence in ICT technology can be interpreted as having low utilization because they recognize that the benefits provided by smart devices are familiar and natural. The results of this study confirm that the digital divide problem in the smart environment is influenced by individual characteristics as well as demographic variables. Therefore, we expect the government to set appropriate policies considering the characteristics of individuals.

Construction in the UK is the second most dangerous industry in terms of fatal and minor injuries according to the 2014 report of HSE. The use of mobile devices such as iPad, Tablets and Smart phones on the live construction projects is also on the increase in the UK due to the 2016 - Level 2 BIM (Building Information Modelling) implementation target, set by the UK Government. Hence, the use of such devices may become a distraction from work activities on the construction sites and will cause a major risk to the end users. The subject of improving safety of BIM use is widely researched, but there is a gap in knowledge about the actual use of the mobile devices and perception of 'Site BIM', on the construction site activities. The main gap identified in the 'Site BIM' is the health and safety aspect of using such devices on the construction sites. A safer way of working with such devices needs to be identified to avoid any potential site hazards and fatalities before the widespread use of the devices are found on the construction projects. In that context, the paper is aimed to highlight the safety issues that are required to address for the successful implementation of the mobile devices for safer use of the 'Site BIM'. Questionnaire survey was used to collect the site information among construction professionals in the UK. The survey findings suggested that a proactive approach may be helpful to stop potential hazards and risks causing by the use of mobile devices and potential measures need to be identified before any injuries and incidents occur. The paper concludes that training, changing size of mobile devices and ensuring a separate induction training for 'Site BIM' tools will improve the health and safety of the end users of the mobile devices at the live construction sites.

세계적인 전자 정부의 발전에 맞추어, 한국의 전자정부는 지난 몇 해 동안 그 발전을 거듭해왔다. 국제 연합 (United Nations) 에 의하면 전에는 한국 전자 정부는 세계 10위권 밖 이었으나, 몇 해 전 부터는 세계 1위에 이르게 되었다. 지속적으로 여러 국가 기관들, 즉 안전행전부와 미래 창조과학부 등이 다양한 전자 정부 활성화 전략(전자 정부 3.0 등)을 제시 하고 추진 중에 있다. 하지만 세계경제 포럼의 국가 네트워크 준비 지수를 보면, 한국은 무선통신이 그 취약점이며, 이는 한국 공공기관의 유무선 통신 활성화와 최근 추세인 BYOD (Bring Your Own Device) 와 Smart office 구현에 부합하는 데 취약하다. 본고는 선진국 사례 및 정책 등을 분석하고 한국 정부에 적합한 BYOD 서비스 구현 및 그 보안을 알아본다.

e-Learning content can be defined as digital content to achieve educational goals. Since it is an educational material that can be distributed in offline, online, and mobile environments, it is important to create content that meets the learner's education environment and educational goals. In particular, if the learner is a public official, the vision, philosophy, and characteristics of each local government must reflect. As non-face-to-face online education expands further due to the COVID-19 pandemic, local governments that have relied on onsite education in the past urgently require developing strong basic competency education and special task competency content that reflect regional characteristics. Such e-learning content, however, hardly exists and the ability to independently develop them is also insufficient. In this circumstance, this case study describes the process of self-production of e-learning content suitable for Busan's characteristics by the Human Resource Development (HRD) Institute of Busan City, a local government. The field of instructional design and instructional technology is always evolving and growing by blending technological innovation into instructional platform design and adapting to the changes in society. Busan HRD Institute (BHI), therefore, tried to implement blended learning by developing content that reflected the recent trend of micro-learning in e-learning through a detailed analysis. For this, an e-learning content developer with certain requirements was selected and contracted, and the process of developing content through a collaboration between the client and developer was described in this study according to the ADDIE model of Instructional Systems Development (ISD).

Safety at sea continues to be an important topic for research. The factors that contribute to safety issues are often complex and unclear. Lack of non-technical skills in such areas as communication, teamworking, situational awareness, decision making etc. are well documented as directly affecting safety in high risk work settings such as on board merchant vessels. Competence in non-technical skills can be affected by various habits and circumstances that influence a worker and result in either positive thinking and behaviour or negative thinking and behaviour. Negative thinking can cause stress, anger, frustration; loneliness etc. and this can possibly result in behaviour or actions that undermine the safety of crew and ship. Factors that may contribute to these negative thoughts and behaviours are many and varied and this paper will be looking at one aspect: mobile phone use. In the Republic of Korea, dependency on mobile phones is uniquely high. Maritime students are also susceptible to such dependency and this paper will demonstrate that the symptoms associated with mobile phone addiction and dependency, and in particular the symptoms of withdrawal, are important factors that need to be mitigated in order to improve safety at sea. Although the benefits of mobile phones are many it will be suggested that over-reliance, dependency or addiction can result in negative thinking or behaviour that may directly or indirectly contribute to the factors that cause incidents and accidents at sea. It will be suggested that the most appropriate method of dealing with this problem is twofold: firstly, through training at the educational level and secondly, by encouraging the shipping industry and government to invest more into providing seafarers with better access to the communication methods that they are used to on shore in order to improve work conditions.
