  • Recently, public safety services have attracted significant attention for their ability to protect people from crimes. Rapid detection of dangerous situations (that is, abnormal situations where someone may be harmed or killed) is required in public safety services to reduce the time required to respond to such situations. This study proposes a novel danger detection technology based on multimodal data, which includes data from multiple sensors (for example, accelerometer, gyroscope, heart rate, air pressure, and global positioning system sensors), and multilog data, which includes contextual logs of humans and places (for example, contextual logs of human activities and crime-ridden districts) over time. To recognize human activity (for example, walk, sit, and punch), the proposed technology uses multimodal data analysis with an attitude heading reference system and long short-term memory. The proposed technology also includes multilog data analysis for detecting whether recognized activities of humans are dangerous. The proposed danger detection technology will benefit public safety services by improving danger detection capabilities.

  • With research data generation on the rise, Institutional Repositories (IR) are one of the tools to manage it. However, the variety of data practices across institutions, domains, communities, etc., often requires dedicated studies in order to identify the research data management (RDM) require- ments and mapping them to IR features to support them. In this study, we investigated the data practices for a few national universities in North Macedonia, including 110 participants from different departments. The methodology we adopted to this end enabled us to derive some of the key RDM requirements for a variety of data-related activities. Finally, we mapped these requirements to 6 features that our participants asked for in an IR solution: (1) create (meta)data and documentation, (2) distribute, share, and promote data, (3) provide access control, (4) store, (5) backup, and (6) archive. This list of IR features could prove useful for any university that has not yet established an IR solution.

  • Standardization work for the ocean data produced by a variety of national oceanographic research projects was conducted in order to establish a national ocean data sharing system. For this work, we first prepared standard proposals for the national research ocean data by reviewing and analyzing of existing international and domestic ocean-data standards. The proposed standards were reviewed and revised by experts in the field of oceanography and academic societies for documentation. The 125-page technical report on the standards of 25 data items was prepared as an output of this research work, which is available free of charge for the public and interested parties. This paper explains the proposed standards of metadata and codes regarding the common properties of all the oceanographic data items. Especially, the standards for the metadata, codes and data formats of 4 physical data items were described in detail. In order to be adopted as the national standards for ocean data, however, the standards suggested here require further development and/or modification based on additional reviews of and ample feedbacks from the relevant academic and technical communities.

  • Purpose - The purpose of this research is to provide insights that can be used for deliberate decision making around challenging big data investments by measuring the economic value of such big data implementations. Research design, data, and methodology - We perform empirical research through an event study. To this end, we measure actual abnormal returns of companies that are triggered by their investment announcements in big data, or firm size information, during the three-year research period. The research period targets a timeframe after the introduction of big data at Korean firms listed on the Korea stock markets. Results - Our empirical findings discover that on the event day and the day after, the abnormal returns are significantly positive. In addition, our further examination of firm size impacts on the abnormal returns does not show any evidence of an effect. Conclusions - Our research suggests that an event study can be useful as an alternative means to measure the return on investment (ROI) for big data in order to lessen the difficulties or decision making around big data investments.

  • High-resolution satellite image processing software should be able to ensure accurate, fast, compact data processing in offline or online environment. In this paper, component software for high-resolution satellite image processing is developed using OpenGIS components and real-time data processing architecture. The developed component software is composed of three major packages, which are data provide package, user interface package, and fast data processing package. The data provider package encodes and decodes diverse image/vector data formats and give identical data access methods to developers. The user interface package supports menus, toolbars, dialogs, and events to use easier. The fast data processing package follows the OpenGIS's data processing standards, which can deal with several processors as components with standard procedural functionalities.

  • 본 연구의 목적은 빅데이터 보안 분야의 기존 연구를 분석하고, 향후 연구 방향을 모색하는 것이다. 이를 위해 국내외의 총62편의 논문을 식별하여, 발간년도, 게재 매체, 전반적인 연구접근 방법, 세부적 연구 방법, 연구 주제 등을 분석하였다. 분석 결과, 빅데이터 보안 연구는 매우 초기 단계로서, 비실증 연구가 압도적인 비중을 차지하고 있고, 관련 개념/기법에 대한 이해를 해나가는 과정으로서 기술-관리-통합의 단계로 진화한 정보보안 분야의 연구 동향에 동조하여 기술적인 연구가 주로 진행되고 있다. 연구 주제 측면에서도 빅데이터 보안에 대한 전반적인 이슈를 다룬 총론적인 연구들이 보안 구현 방법론, 분야별 이슈 등의 각론적 연구에 비해 높은 비중을 나타내는 등 초기 단계의 모습을 나타내고 있다. 향후 유망한 연구 분야로는 빅데이터 보안에 대한 전반적인 프레임워크 수립, 업종별 빅데이터 보안에 대한 연구, 빅데이터 보안 관련 정부 정책 분석 등을 들 수 있다. 빅데이터 보안 분야의 연구는 본격적으로 시작된 지 얼마 되지 않아, 연구 결과가 상대적으로 매우 부족한 편이다. 앞으로 다양한 관점에서 빅데이터 보안과 관련해 풍부한 주제를 다루는 연구가 진행되기를 기대한다.
