The purpose of this paper is to discover how the use of digital applications can affect students' attitudes toward positive classroom participation and performance in learning a foreign language. Participants of this study were 128 students who took a foreign language class at a high school in central Korea. To find out students' perceptions and attitudes toward the effect of using a digital application for their foreign language study, online questionnaire and focus-group interview were conducted. Our research findings revealed that these students could engage in active language learning and experience learning improvement while studying a foreign language with digital applications. The improvement was possible by creating more interactive activities and quizzes. In addition, the digital application provided students immediate feedback. It gave students and teachers various motivations beyond the traditional 'chalk and talk' format of text-only-classes. This study provides an overview of the usefulness of digital application. In addition, it provides understanding for students' perceptions and involvement using digital application in a foreign language classroom.

Recently, MPEG has opened activity to standardize scene representation for lightweight applications such as in mobile phones. The standard is named lightweight applications scene representation (LASeR) and can be applied to improve and make efficient rich media applications and services on mobile devices. In this standard, we proposed an efficient type codec for point data to maximize the bit efficiency of LASeR. In this paper, we describe the new method and the test results of the proposed scheme.

Digital holography (DH) is a potentially disruptive new technology for many areas of imaging science, especially in microscopy and metrology. DH offers a number of significant advantages such as the ability to acquire holograms rapidly, availability of complete amplitude and phase information of the optical field, and versatility of the interferometric and image processing techniques. This article provides a review of the digital holography, with an emphasis on its applications in biomedical microscopy. The quantitative phase microscopy by DH is described including some of the special techniques such as optical phase unwrapping and holography of total internal reflection. Tomographic imaging by digital interference holography (DIH) and related methods is described, as well as its applications in ophthalmic imaging and in biometry. Holographic manipulation and monitoring of cells and cellular components is another exciting new area of research. We discuss some of the current issues, trends, and potentials.

본 논문에서는 최근 활발히 진화하고 있는 디지털 융합 관련 스마트 어플리케이션을 파악하고 디지털 정책 시사점을 제시하였다. 스마트 어플리케이션에 관한 기존의 많은 연구가 사용자 효용과 기술수용성 등을 중심으로 진행된 반면 정책 관점에 초점을 맞춘 연구는 상대적으로 미흡하였다. 본 연구에서는 이러한 연구의 갭을 메우고자 8개의 핵심 스마트 어플리케이션을 파악하고 이에 대한 삶의 질, 공공 이익, 역작용 등을 체계화하고 델파이 방법론에 기초한 실증분석을 통하여 검증하였다. 8개의 핵심 어플리케이션은 스마트워크와 스마트 상거래로 구분하여 각각 4개의 대표적 어플리케이션을 채택하였다. 본 연구 결과는 향후 관련분야의 디지털 정책 연구에 유용한 기초 결과로 사용될 수 있다.

Digital models for a cable-stayed bridge are defined considering data-driven engineering from design to construction. Algorithms for digital object generation of each component of the cable-stayed bridge were developed. Using these algorithms, Level-3 BIM practices can be realized from design stages. Based on previous practices, digital object library can be accumulated. Basic digital models are modified according to given design conditions by a designer. Once design models are planned, various applications using the models are linked the models such as estimation, drawings and mechanical properties. Federated bridge models are delivered to construction stages. In construction stage, the models can be efficiently revised according to the changed situations during construction phases. In this paper, measured coordinates are imported to the model generation algorithms and revised models are obtained. Augmented reality devices and their applications are proposed. AR simulations in construction site and in office condition are tested. From this pilot test of digital models, it can be said that Level-3 BIM practices can be realized by using in-house modeling algorithms according to different purposes.

본 연구는 국내의 대표적인 배달 애플리케이션 3곳을 비교분석 하기 위한 연구이다. 모바일 사용 증가에 따라 배달 애플리케이션의 사용 빈도는 나날이 늘고 있다. 그런데도 사용성에서는 아직도 문제가 제기되고 있다. 배달의 민족, 요기요, 배달통 이렇게 세 가지의 배달 애플리케이션의 사용성에 대한 선호도를 심층 면접을 통해 분석하였다. 사용자 경험 만족에 영향을 미치는 요인을 허니콤에 기반을 둔 7점 척도를 통해 확인하였고, 심층 면접과 7점 척도의 결과가 비슷하게 나옴으로써, 사용자들이 압도적으로 선호하는 배달 애플리케이션이 무엇이며 이유가 무엇인지 알 수가 있었다. 이 연구는 배달 애플리케이션에 대한 사용자 경험을 분석하고 각 업체의 장점을 도출시켜 애플리케이션에 적용하고, 더 나아가 면담을 통해 얻게 된 새로운 기술적 아이디어를 통해 애플리케이션의 서비스와 사용성을 높이는 데 의의가 있다.
