Volatile organic compounds(VOCs) are regarded as a harmful cause substance not only causing air pollutions but also causing global warming phenomenon. For this reason, VOCs are managed politically to reduce emissions by each country. In particular, the vapor from the gas station contains VOCs which is harmful to the human body such as carcinogens benzene and pollute the atmosphere, the Ministry of Environment defined every gas station must install vapor recovery equipment to recover volatile organic compounds. Recently, there are many accidents caused by existing vapor treatment methods, the liquefaction recovery technology is getting the spotlight to cool the vapor at the field. However, because the liquefaction recovery technology have risks of fire or explosion in accordance with temperature, the real time monitoring is critical factor. In this paper, we implement an Android-based monitoring application for liquified vapor recovery device which attached sensor module for temperature and power to monitoring real time information.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects App. game based on smart phone. Expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that exploration, action, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

The purpose of this review was to evaluate the effects of diabetes management program using mobile appllication. A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: the PRISMA Statement was conducted. Studies published between 2004 and 2014 were reviewed using the following databases: Ovid, CINAHL and Cochrane library. The keywords used were (app*OR mobile) AND (nurs* OR health* OR medic*) AND (diabet*). Selected studies were assessed for methodological quality using Scottish Intercollegiate Guidelines Network (SIGN)' Checklist. Three hundred seventy five studies were identified, All the 3 studies found mobile application as a valid strategy on clinical usefulness in diabetes management. This review provides updated evidence for app-based management program in diabetes management. Further studies are needed to increase generalizability using randomized controlled trials, enough sample size. In addition, valid measurements are needed to assess the main outcomes.

The flipped learning is an inverted teaching model where students learn the basic concepts using short videos at home and then come to class to enable effective practice and interactions among teachers and students. However, due to the students' lack of self-regulated competence, most students have difficulties of comprehending the instructional materials out of class by themselves. In this paper, we develop an interactive app for active flipped learning in the mathematics courses in the elementary schools. We examine the effectiveness of the active flipped learning on learners groups with different achievement levels in learning 4th grade mathematics concepts in the elementary schools. The pretest and posttest survey results show that the proposed flipped learning approach has better performance compared to the traditional flipped learning approach.

Many of crimes are solved by the report of people. Therefore, countries pay compensation to crime reporter. However, the current system of compensation is focused on the report of criminal fact and criminals arrest, so that there is no compensation on the providing evidence. On the other hand, since the current judicial system adopted the principle of trial by evidence, all the facts are made by the evidence. But it is impossible to obtain all the evidence only by law enforcement agencies. Therefore, it is necessary for people to report the evidence positively. So it is necessary to positively take advantages of smart phones, vehicle black boxes and cctvs. Various incentives such as compensation would be needed to require the evidence of smartphone or black box, cctv. In order to strengthen evidence report, it will be needed the legislation of crime report compensation, smartphone apps development including the provision of various incentives.

In order to vitalize the Rich Communication Service-e(RCS-e) service, RCS-e users need various ways to use RCS including RCS-e apps. A RCS standards organization has suggested Application Program Interface(API). Since it only dealt with functional requirements, it was not enough to implement the API. This paper suggests an open API framework that can utilize RCS-e through a web interface. By using the framework, web developers can implement various RCS-e-enabled web applications. A system architecture is defined for the framework. Call flows for establishing a RCS-e session between the framework and other nodes are defined. Also, rules and examples for translating protocols between them are provided. Finally, performance evaluation proves that the proposed framework does not add loads to the existing network infrastructure.

Recently, due to increases in the numbers of nursing students, there are many cases of clinical practice in remote areas other than in hospitals near a school. In this regard, the Korea Institute of Nursing Evaluation emphasizes the securing of safety, the provision of regulations, and countermeasures related to long-term practices of nursing students. The purpose of this study is to develop a safety management application for nursing students who are practicing at a distance. This application configuration consists of accommodation location information, nursing student location information check, and notification of the professor in charge. The location information of nursing students was based on their location on weekdays from 10 pm to 11 pm, due to the work schedule of the nursing students. For this reason, nursing students can use this app after their clinical practice; if the student is out of the safety radius or there is a problem, a risk notification can be provided through a service and a rescue request can be made.

우리나라 특성화고는 산업사회의 각 분야에서 종사할 유능한 인재를 양성하고 합리적이며 능률적인 직업인을 육성하려는 목표로 1998년에 도입되었다. 2010년에는 독일, 스위스, 오스트리아 등에서 자리 잡은 마이스터고 제도를 도입하여 변화를 시도하였다. 유럽에서의 마이스터고는 창업 성공률이 98%에 이를 정도로 창업의지가 높은 학생들로 구성되었다. 우리나라 또한 특성화고 학생들의 창업의지를 높이기 위해서 정부와 민간 기관에서 다양한 시도를 하였다. 창업진흥원의 기업가 마인드 확산 교육 비즈쿨(2002년), 한국시민자원봉사회의 특성화고 대상 창업 마인드 확산 경진대회 Be the CEO(2004년), 아산나눔재단과 어썸스쿨의 앙트러프러너십 교육 히어로스쿨(2014년) 등이 사례이다. 본 저자도 2011년부터 중소벤처기업부와 SK가 공동으로 주최하는 고교생 앱 개발경진대회를 직접 운영하면서 특성화고 학생들의 창업의지를 높이기 위한 방안에 대해 오랫동안 고민하였다. 본 연구에서는 특성화고 학생들의 앙트러프러너십이 창업의지에 미치는 영향을 연구하였다. 앙트러프러너십의 구성요소는 Miller(1983)가 주장한 위험감수성, 혁신성, 진취성에 기회인지를 추가하였다. 또한, 특성화고 학생들이 학교 교육과 다양한 외부활동을 통하여 접하고 있는 창업멘토링이 앙트러프러너십 구성요소와 창업의지간에 조절효과가 있는지 밝히고자 하였다. 이를 위해 전국 491개(2017년 말) 특성화고등학교 중 지역별로 안배하여 14개 학교 학생들을 대상으로 설문을 시행하였으며, 설문서 287부를 실증분석에 활용하였다. 연구분석 결과 특성화고 학생의 기회인지, 위험감수성, 혁신성, 진취성은 모두 창업의지에 긍정적인 영향을 미치는 것으로 나타났다. 한편 기회인지, 위험감수성 등 앙트러프러너십 요소와 창업의지 관계에서 창업멘토링의 조절효과는 진취성에만 긍정적인 영향을 미치는 것으로 나타났다. 창업멘토링의 조절효과가 진취성에만 국한된 것은 특성화고는 창업보다는 취업 중심의 정책을 운영 중이어서 앙트러프러너십은 높으나 창업의지가 희박한 학생이 많았고, 기존의 창업멘토링 내용이 학생들의 창업의지를 높이는데 실제적인 도움이 되지 못하였으며, 창업을 가로막는 제도 때문에 멘토링 만으로는 창업의지를 높이는데 한계가 존재하였다. 본 연구의 결과가 우리나라 특성화고 학생들의 창업의지를 높이는 방안에 대한 연구를 촉발하는데 조그만 보탬이 되기를 바란다. 또한, 창업의지가 높은 특성화고 학생들이 창업을 실행할 수 있는 환경이 구축되고, 특성화고가 취업중심의 정책에서 창업친화적인 정책으로 개선하는 데 촉매제가 되기를 바란다.

In this paper, we developed a phone call display system or "alimi" for displaying the received phone data at limited space that can not carry a mobile phone and and its validity was confirmed. It consists of a data communication application transmitting the phone data via bluetooth, a RF data repeater to extend the range of data communication, and a display system part for displaying the received phone data to the phone user. It has economy in terms of system installation because the implementation of the proposed system is simple and low cost installation is possible. As ordinary mobile phones users using the system can easily utilize it by downloading the application on the app. store, it has economy and convenience checking whether a call is received.
