  • 정보화시대로 넘어오면서 코딩 역시 중요한 교육으로 자리 잡고 있다. 초등학교는 물론 중, 고등학교도 교육적인 측면에서 프로그래밍을 중요시하고 있으며 C언어나 Java는 더이상 개발자만을 위한 언어로 인지되지 않는다. 하지만 코딩의 결과만 의존할 경우 정보보호를 하는 시큐어 코딩의 요소를 중요하게 여기지 않을 수 있다. 그 결과 DB는 물론 서버 에러를 비롯해 개인정보는 많은 위험에 노출될 수 있다. 기본적인 프로그래밍을 숙지한 개발자를 위해 더욱 안전한 코딩을 교육하고자 시큐어 C 코딩 앱을 기획하게 되었고, 정보보호를 코딩의 중요한 요소로 인지하기를 기대한다.

  • 본 논문에서 거푸집의 가장취약 부분인 접합부위에 로드센서를 부착하여 실시간 콘크리트 측압을 측정 할 수 있으며, 관리자는 모니터링을 통하여 확인 할 수 있도록 하며 LORA의 저전력 장거리 통신망을 사용하는 디바이스를 개발하여 로드센서에 측정한 값을 데이터변경, 웹 기반의 클라우드 서비스로 발송하여 PC 및 Mobile로 확인 할 수 있는 시스템을 구축하였다. 여러가지 센서로부터 데이터를 수신하여 모바일로 송신해 주는 무선송수신기의 개발을 원하고 있으며, 하중센서, 경사도센서, 풍향센서 등 다중 데이터값을 수신할 수 있어야 한다. 이렇게 구성된 센서와 데이터의 수신을 통해서 콘크리트 타설시 발생하는 측압을 측정하고 공사기간 동안 별도의 전원 공급 없이 작동이 유지될 수 있는 시스템을 구축하였다. 수요자가 Application과 호환이 이루어져야 하며 또한 MEMS센서를 이용하여 상태를 모니터링 하고 임계값을 지정하여 이상 신호 발생시 위험상황에 대해서 인공지능기법을 이용하여 관리자에게 알림을 주어 효과적으로 사용할 수 있는 시스템을 개발하였다.

  • As artificial intelligence has become commonplace in various fields, the transparency of AI in its development and implementation has become an important issue. In safety-critical areas, the eXplainable and/or understandable of artificial intelligence is being actively studied. On the other hand, machine learning have been applied to the intelligence of self-organizing network (SON), but transparency in this application has been neglected, despite the critical decision-makings in the operation of mobile communication systems. We describes concepts of eXplainable machine learning (ML), along with research trends, major issues, and research directions. After summarizing the ML research on SON, research directions are analyzed for explainable ML required in intelligent SON of beyond 5G and 6G communication.

  • 국내 표준무선인터넷플랫폼인 WIPI에 대한 확장성 연구는 미들웨어 차원에서 여러 연구로 진행되었지만 이 논문에서는 애플리케이션 레벨에서 MDA에서의 모델변환을 적용, 다른 플랫폼에서의 애플리케이션을 쉽게 WIPI 플랫폼으로 포팅할 수 있는 방법을 제안한다. 도메인 모델의 식별과 메타모델 정의, 그리고 변환규칙 등을 정의하여 XML 및 XSLT를 이용한 모델 변환을 수행한다. 또한 서로 다른 개발 플랫폼에서의 API매핑과 WIPI 기반 도메인 제약조건 등을 인식하고 향후 제한적이지만 제안사항을 적용한 모델변환도구의 개발과 테스트 기능 지원으로 연구를 진행한다.

  • 모바일 단말기 컨텐츠 제공자에서 생산되는 대부분의 모바일 응용 SW는 짧은 개발 기간과 생명주기, 그리고 시장 선점이라는 특성을 가지고 있다. 또한 국내 모바일 응용 SW의 경우 다양한 모바일 단말기의 화면크기 그리고 다양한 모바일 플랫폼을 지원해야 하는 특성과 제약사항을 가지고 있다. 이러한 제약사항을 극복하기 위해서 본 논문에서는 모바일 응용 SW의 사용자 인터페이스 모델을 제시하고 있으며 이를 이용하여 모바일 응용 SW개발 방법을 제시한다. 모바일 플랫폼에 독립적인 인터페이스 모델을 사용함으로써 개발자는 사용자인터페이스 개발에 소모되는 시간을 최소화하고, 구현에 그 정보를 사용함으로써 기민하고 좀 더 빠르게 모바일 응용 SW를 개발할 수 있는 장점을 가진다.

  • The Republic of Korea in the real economy to a knowledge economy, and a center of creativity and imagination in the creative economy is changing the paradigm. As the core of creating economic, creative industries with the technology and information play an important role in the industry individuals. In order to solve the problem of the polarization of the economy and high youth unemployment rate of Korea, to recognize the role of the creative industries, as objection part, dimensions pan-national and one creative companies in industries of Mobile Apps various policies that support has been promoted. Support these policies to be able to contribute to the establishment of the success of mobile apps one-person creating company, we performed this study targeting one-person company that creates mobile apps area, we conducted a demonstration study of success factors, and thus more effective and efficient in an attempt to seek out support measures. In this study, we derive a research 4 hypothesis about the success factors of one creative enterprise through literature discussion, a study was made on the basis of empirical data of one-person company that creates mobile apps. The results of the analysis, first, if the development rate of the mobile application technology is fast and a new competition associated product is appeared, it was possible to find a tendency to be higher at the performance quantitative companies. Second, if the founder is a founding for the benefit and rewarding work and come to terms with the risk, it was possible to discover tends to be higher achievement quantitative. Third, if one-person company select a target market with capture intensively, it was possible to find a tendency for higher qualitative results. Fourth, it could be found that the reliability of the contact frequency of the network related performance business environment these characteristics enterprise management strategy and act as a significant modulatory effect. Provision of information relating to management and entrepreneurship education to be one creative enterprise is required, these results suggest that there is a provision continuing need for the opportunity to be able to meet and network and reliable variety have. In this study, to take advantage to promote the elimination measures that can increase the likelihood of success of the company of institutions to support one company that creates knowledge-based, such as in the field of mobile application.

  • Purpose: The purpose of this study was to investigate the effects of a profanity intervention application on interpersonal relationship ability, aggression, and empathic ability among female middle school students. Method: The subjects of the present study were freshmen students at a girls' middle school in Gyeonggi-do. The profanity intervention application was implemented from November 20th to 27th, 2017. The pre- and post-tests were conducted one week before and two weeks after the intervention, respectively. The study was designed as a randomized controlled study and the collected data were analyzed using SPSS/WIN 23.0 (Chicago, IL). A homogeneity test between the two groups was performed using $x^2$ test, Fisher's exact test, independent t-test, and ANCOVA. Results: The two groups were found to be homogeneous in the pre-test. After the implementation of the profanity intervention application, aggression significantly decreased (F=20.17, p<.001) and interpersonal reactivity (F=5.92, p=.023) and empathy (F=11.10, p=.003) significantly increased in the experimental group compared to the control group. Among the factors related with aggression, verbal aggression, anger, and hostility significantly decreased in the experimental group. Meanwhile, among the factors of interpersonal reactivity, empathic concern and perspective-taking significantly increased and, among the factors of empathy, cognitive empathy significantly increased in the experimental group compared to the control group. Conclusion: Based on the findings of the present study, various intervention programs that can consistently improve the moral and ethical sensitivity of students should be presented starting from elementary school to prevent verbal violence in adolescents.

  • This study is a follow-up study of Smart-phone Application Content Development for the Measurement and Management of Adolescents' Depression(J. S. Park et al., 2016), that designing and implementing a smart-phone application based on cognitive behavioral therapy. This app facilitates analysis of depressive symptoms, and a simple, continuous self-check. Through this, the app will allow for continuous management of the psychological states by avoiding one-off or comprehensive analysis and diagnosis of depression, unlike previous app. We also aim to make a connection to the practical counseling services. To achieve this goal, we examined not only existing studies on youth depression, but also mobile applications related to depression.

  • Purpose: The purpose of this study was to compare the concurrent validity and test-retest reliability of 'KPIMT Torticollis Protractor', a smart phone and I-pad application for convenient range of motion measurement, and 'Image J', an analysis software with high reliability and validity, according to head tilt and active cervical rotation angle. This was done to determine the clinical utility of 'KPIMT Torticollis Protractor'. Methods: Head tilt and active cervical spine rotation angles of 40 children with congenital muscular torticollis were measured using Image J and KPIMT Torticollis Protractor, respectively. The level of concurrent validity and inter-rater and intra-rater reliability between the two measurement methods were analyzed. Results: For forty participants, the concurrent validity between Image J and KPIMT Torticollis Protractor showed very high validity with ICC of ICC 0.977 (0.995-0.999), 0.994 (0.994-0.998), CVME% 0.71-0.72%, SEM% 0.31-0.34%, MDC% 0.86-0.94%. The test-retest intra-rater reliability showed very high reliability ICC 0.911 (0.911-0.966), CVME% 0.71%, SEM% 0.34-0.36%, MDC% 0.81-0.94%. The test-retest inter-rater showed very high reliability ICC 0.936 (0.933-0.957), CVME% 0.70%, SEM% 0.34-0.35%, MDC% 0.81-0.83%. Conclusion: The KPIMT Torticollis Protractor, a smart phone and IPD application, is a highly reliable and valid device for angle measurement in children with congenital myotonia and can be easily used in clinical practice.
