Severe mine disasters have continued to occur around the world. To ensure worker's health and safety and enhance the productivity, a number of studies have been conducted for the development of wireless sensor network (WSN), environmental monitoring, and communication system in underground mines. An increase in development and application of these systems has just begun with the introduction of information and communication technology into the mining industry in Korea, and yet there have been only a few studies that considered the underground mine ventilation system. This study presented the literature review on the development of WSN and environmental monitoring in underground mines, and especially, on 7 subjects in terms of underground mine ventilation. Moreover, studies that especially conducted real-time environmental monitoring were reviewed and categorized by each commercial software commonly utilized for the ventilation network analysis. For the application in domestic underground mines, further issues were discussed regarding research subjects that may be needed in the future and domestic environmental standards that has been used in the underground mine operation. This paper is expected to be useful for the development of WSN-based environmental monitoring and communication system, as well as for related studies in the future.

This research aims to provide a solution for the improvement of private security according to the change in criminal environment. The main cause of crime can be found in the anti-functional dimensions including value set disorder, social phenomenon variation, information-based, globalization and urbanization. In this environment, the private security sector has dramatically increased in a quantitative viewpoint, but it is insufficient in a qualitative viewpoint. This paper recognized this problem and demonstrates a solution for improvement through classifying elements of private security into relevant legislation, education institutions, security companies and security associations. The analysis result is a follows: First, motivation and satisfaction rate of escort and security related major has shown to be high. However, respondents evaluated the guard educational institution negatively. Second, the motivation of entering into the private security sector for internal staffs has shown to be positive and sound. However, the job satisfaction rate has shown to be low due to excessive competition, negative perception of occupation and low earning. Third, respondents gave an average mark to the Security Association's management and operation. In addition, the mutual-aid project received the same mark. Negative feedbacks were given to the protection of member's interest and to association operation and policy, while positive feedbacks were given to the degree of member's cooperation towards association policies.

The continuous development of digital technology has actualized ubiquitous computing, and the environment of human life has come to face changes. Prediction of the future so that human life may be prepared can be very important. A number of predictions of ubiquitous space are presented, ranging from related professional research to mass media, However, proper analyses and understanding are required to understand ubiquitous space and apply it to design. This study seeks to understand ubiquitous space through analysis of the trend in digital technology from a new perspective, to research cases, and predict the future of ubiquitous space. Human, object, and environment have been set as basic factors as the subjects smoothly exchanges various types of information in the physical space, and the trend in digital technology is analyzed. From a human-oriented perspective, the background and development trend of digital technology has been analyzed under the theme of interaction and interlace. From an object-oriented perspective, an analysis was unfolded under the theme of products' evolvement from radios to robots. From an environment-focused perspective, an analysis has been carried out under the theme of situation recognition, intrinsic factors, and integration and connectivity. By applying the analytic results, the types of studies that predict the future of ubiquitous space and generate concepts have been classified and analyzed into three different types of studies for experiment, industry, and public. In this manner, ubiquitous space has been forecasted. This study seeks a systematic analysis of the understanding of the trends in digital technology and employs a case study of ubiquitous space based on systematic analysis. In consideration of all these, this study is expected to contribute to concept generation and development by designers.

The purposes of this study are to derive supportive measures for the effective operation of vocational education and training high schools participating in the apprenticeship system (apprenticeship schools) and make policy suggestions by analyzing the need analysis and investigating the importance and the difficulty of teachers regarding the operation of those schools. To achieve these purposes, the study developed a questionnaire by deriving the areas and items for the operation of apprenticeship schools, and analyzed 121 completed questionnaires of head and senior teachers who manage the apprenticeship programs across the nation after conducting a survey. The findings of this study can be summarized as follows: First, the teachers of apprenticeship schools found all the operation areas of the schools are important but difficult. Out of the operation areas, teachers had relatively high needs for 'promotion, selection and management of enterprises', 'student management', 'development of apprenticeship programs, formation of the curriculum, and establishment of operation plans of the curriculum'. Second, the teachers found all the detailed items of the operation areas of apprenticeship schools are important but difficult generally. According to the results, it is required to relax the criteria for forming apprenticeship organizations; operate the local government-oriented apprenticeship system; establish information systems between schools and enterprises; improve the support methods of relevant agencies; and increase incentives of teachers who are in charge of apprenticeship programs. It is also necessary to operate exclusive agencies supporting for OJT; operate apprenticeship education centers of local small and medium-sized business associations; provide exclusive supervision of students; cultivate teachers who support industry-academia cooperation; and legislate on the NCS-based qualifications.

With the growing interest being reflected in the FinTech industry, much attention has been paid to mobile easy payment services as well. In the era of mobile commerce, the core advantage of using mobile easy payment services(simplifying complex payment procedures and thus facilitating user convenience and reducing the chance of giving up payment) are being more emphasized. Mobile easy payment service market not only includes mobile easy payment service providers but also users, non-users, affiliates, banks, and credit card companies as main stakeholders. Exploring those stakeholders is thus important to thoroughly understand such market. However, extant literature on mobile easy payment services mostly focuses on examining adoption intention of users or non-users. This study, an exploratory research based on interviews, thus aims to extract driving as well as inhibiting factors of mobile easy payment service use from six different perspectives (i.e., social platform, bank, credit card company, affiliate, user, and non-user) and analyze a sequence of cause and effect for each factor. For this, the causal loop diagram was developed to deduce key issues and propose an alternative. Theoretical and practical implications of this study will also be discussed.
