최근 스마트 기기 시장이 커지며 이와 함께 스마트 기기를 이용한 연구가 활발하다. 현재 많이 사용되는 스마트 기기인 스마트워치와 스마트폰에는 다양한 센서들이 내장되어있다. 이 센서들을 통해 생성된 데이터를 이용하면 사용자의 행동 분류, 건강관리 등 사용자에게 도움이 되는 서비스를 제공할 수 있다. 본 논문에서는 어플리케이션 개발을 통해 상용 스마트기기인 갤럭시 워치 4와 갤럭시 S10에 내장되어있는 센서의 원시데이터를 수집하고 수집한 데이터를 oneM2M 표준 플랫폼에 저장하였다. oneM2M 표준 플랫폼에 저장된 데이터는 API를 통해 손쉽게 사용할 수 있으며 여러 대의 스마트 기기 데이터를 수집하고 빅데이터를 구축한다면 많은 연구자들이 보다 편리하게 데이터를 이용하여 다양한 의미 있는 연구들을 진행할 수 있을 것이다.

This study aims to analyze the causes of a new product failure by using system safety methods, focusing on the case of Samsung Galaxy Note7. However, when analyzing the causes of a product failure, if only technical problems are too emphasized, it is likely to miss other more meaningful causes of a failure. Thus, we claim that the root causes of a product failure should be identified in a broad perspective of integrated systems that include non-technical as well as technical elements. With this viewpoint, we investigated the failure of Samsung Galaxy Note7, by using Root Cause Analysis(RCA) and Fault Tree Analysis (FTA). The results showed that it is necessary to address not only the technical issues but also other non-technical issues, such as a very impetuous launch of a new product due to a very tough competition in the market. Additionally, we also found that RCA and FTA could be a useful tool for analyzing the causes of a new product failure from the viewpoint of an integrated system comprising technical and management elements.

In this study, to solve the existing inefficient stem analysis process and expensive equipment cost problems, a method for detecting and analyzing tree rings using smartphone images was proposed and a semi-automated computer program (TRIO, Tree Ring Information) was developed. TRIO can measure the annual ring radius and save the results to Excel. Since TRIO uses smartphone images, the results may vary depending on the quality of the smartphone camera. Therefore, using the Samsung Galaxy S10 and Tap 2, 30 dics images of Pinus rigida were acquired and analyzed, and these were compared with WinDENDROTM. As a result of the study, both Samsung Galaxy S10 and S2 showed significant results with WinDENDROTM, and the R2 value of S10 had a high correlation as 0.976, and RMSE was analyzed as 0.4199, and very similar results were output. The R2 value of S2 was 0.975 and the RMSE was 0.4232, showing no significant difference from S10. Accordingly, the TRIO developed in this study analyzed the annual radius value very similar to WinDENDROTM.

New product preannouncement through global supply chain management and international strategic alliances is a critical issue for firm's survive and gaining the competitive advantage in the global smart-phone market. To identify the impact of exploration alliance and exploitation alliance on the short-term's Firm Performance, respectively, This study implemented the event study and the cross sectional regression analysis, focusing on the case of Galaxy Note series. Research results identified that new technologies by exploration alliance and the existing technologies through exploitation alliance have a positive effect on the short-term's performance of vendors related. Furthermore, information for the new products showed higher the excess earning rate than information related to the existing technologies. This implies the firms that provides new technologies have a stronger innovative ability than the companies serving the existing technologies, recognizing as a positive signal in the market. Finally, this study implicates that new technologies by exploration alliance enhances innovative abilities from new product preannouncement, and is a critical variable that can determines whether to survive in the market.

미디어 학자 맥루한(M. McLuhan)은 미디어 테크놀로지의 커뮤니케이션적 의미를 통찰하고 그 미래를 전망한 사상가로 유명하다. <구텐베르크 갤럭시 (Gutenberg Galaxy)>에서 그는 인쇄술에 의해 인간적인 커뮤니케이션을 박탈당하게 되었다고 진단하면서 종이 책의 종언을 예언했다. 인간 커뮤니케이션을 왜곡시킨 미디어가 바로 인쇄기라고 주장하고, 그 인쇄기로부터 인간커뮤니케이션을 해방시킨 미디어로서 텔레비전을 칭송하고 있다. 이로써 그는 미디어가 추동하는 패러다임의 변동을 주장하는데, 전자미디어의 등장이 선형적이며 분리적 형태의 인간커뮤니케이션을 재원형화 함으로써 감성적 커뮤니케이션 패러다임으로의 전환을 야기하고 있다고 설명한다.

Recently, the number of attacks by malicious application has significantly increased, targeting Android-platform mobile terminal such as Samsung Galaxy Note and Galaxy Tab 10.1. The malicious application can be distributed to currently used mobile devices through open market masquerading as an normal application. An attacker inserts malicious code into an application, which might threaten privacy by rooting attack. Once the rooting attack is successful, malicious code can collect and steal private data stored in mobile terminal, for example, SMS messages, contacts list, and public key certificate for banking. To protect the private information from the malicious attack, malicious code detection, rooting attack detection and countermeasure method are required. To meet this end, this paper investigates rooting attack mechanism for Android-platform mobile terminal. Based on that, this paper proposes countermeasure system that enables to extract and collect events related to attacks occurring from mobile terminal, which contributes to active protection from malicious attacks.

Background and Objectives : Acoustic analysis of voice could be influenced so much by the quality of voice files which were recorded by recording device. In clinical practice, voice files that were recorded by analysis program directly or portable digital recording device were analyzed mostly. This study examined the feasibility of using Galaxy smartphone recordings for acoustic analysis of voice. Materials and Methods : Acoustic measures were compared between voice signals recorded from 30 normal speakers (15 males and 15 females) through Galaxy smartphone, portable digital recording device and CSL. Fo, jitter, shimmer, NHR (Noise-Harmony ratio) and Formant frequencies were analyzed by MDVP. Results : Fo, Jitter, Shimmer, NHR and formant frequencies from 3 devices were no significantly difference. The intraclass correlation coefficient (ICC) was higher between each of the voice perturbation measures. Conclusion : The findings indicated that Galaxy smartphone recording system was useful device for acoustic analysis of voice. Furthermore, Galaxy smartphone can be applied widely in various way for acoustic analysis of voice.
