This study intends to evaluate the balance ability of Korean adults in their 20s and create balance indicators using digital equipment(FRA 510 S). The study participants participated in 50 men and women in their 20s without musculoskeletal and nervous system diseases. For data analysis, Repeated Measures ANOVA was used. As a result of the study, it was confirmed that the movement of the body weight was higher when the eyes were closed and the test was performed than when the eyes were opened on a flat floor and a balance pad(47cm×39cm×5.5cm). And there was no difference according to the gender of men and women. In a future study, it is considered that the balance ability of normal elderly people will be evaluated, and the balance index of normal adults in Korea will be created and applied to the evaluation of patients with impaired balance ability.

The research conducted here focuses on the definition and organization of information privacy concerns in e-commerce process. Based on the identified concept of information privacy concerns(IPC), this study additionally explores the interrelationships among consumers' individual characteristics(self-efficacy, digital literacy, customer alienation), customer satisfaction and intention to buy. Through empirical model analysis, this study found that self-efficacy and digital literacy affect negatively IPC, while customer alienation has an positive effect on IPC. IPC affects positively customer satisfaction. Academically, this study extends IPC to an empirical research model by identifying the conceptualization and organization of IPC. Moreover, practically, e-commerce providers can develop how to relieve IPC of online consumers.

With the development of information and communication technology, various data including digital data have increased exponentially. In a society where such data utilization is generalized, criminal investigation processes and trial processes have also been influenced. However, in comparison with the progress of the technical capability and analytical capability of digital certification which is increasing exponentially, the establishment of the digital forensic related legal system is still in short supply. Therefore, it is necessary to activate balanced research for legal recognition of digital certification. Therefore, in this research, meta analysis was conducted to grasp trends of research related to digital forensics and to provide objective data for research revitalization.

대부분의 정보시스템 개발 종사자들은 대단위 관계형 데이터베이스의 정확한 개념 정립이 되어 있지 않은 상태에서 시스템 개발에 접근한다. 이것은 많은 비효율을 발생시켜 시스템 개발 생산성 및 품질의 저하를 가져오며, 시스템 수행속도를 현저히 떨어뜨린다. 특히, 관계형 데이터베이스는 활용 능력에 따라 효율의 차이가 매우 크게 나타나며, 이는 바로 프로젝트의 성공과 실패를 판가름하게 된다. 이 글에서는 관계형 데이터베이스를 보다 효율적으로 활용할 수 있는 다양한 방법과 실무에서 개발자 일량을 감소시키면서 수행속도를 향상시키는 솔루션을 제공하고자 한다.

디지털 기술의 급속한 발전에 의한 디지털 방송의 도입은 방송환경에 커다란 변혁을 초래하고 있다. 기술의 발전은 방송, 통신, 컴퓨터를 융합시킨 새로운 미디어 서비스를 등장시키고 있으며, 이러한 미디어의 융합은 지금까지 독자적인 영역에서 발전하여 오던 각각의 미디어들이 가지고 있는 한계성 또는 단점을 상호보완적으로 개선함으로써 서비스 능력을 대폭적으로 향상시키는 방향으로 전개되고 있다. 이와같은 디지털 시대의 대변혁은 멀티미디어 서비스를 그 중심축으로 하고 있으며, 이른바 방송통신 융합시대의 경쟁력 있는 서비스를 도입하기 위한 미디어간, 국가간의 경계영역을 초월한 글로벌 경쟁체제가 급속히 진전되어 가고 있다. 이와 같은 미디어의 융합 현상에 따라 제작 환경도 새로운 디지털 방송 서비스를 효율적으로 지원하도록 전환되어야 한다. 디지털 방송의 특징인 고품질 및 다채널 시대를 맞아 방송 콘텐츠의 재활용도를 높이는 것은 매우 중요하며, 데이터 방송, 인터넷 방송 등 다양한 기능의 서비스를 도입하기 위해선 제작 체계의 개선이 뒷받침되어야 한다. 따라서 본 논문에서는 새로운 제작 환경에 대해서 살펴보고자 한다. 특히, 컴퓨터 기반의 제작 환경 구축에 핵심 요소인 넌리니어 편집시스템과 방송 콘텐츠를 효율적으로 관리하고 재활용할 수 있는 디지털 아카이브에 대해 소개하고자 한다. 테이프 대신 하드디스크를 기록 매체로 하는 넌리니어(non-linear) 시스템의 등장에 따라 방송 프로그램 제작에 대한 새로운 개념의 정립이 필요하게 되었으며, 이를 근간으로 하는 새로운 프로그램 제작환경, 즉 네트워크에 의해 컴퓨터와 데이터베이스를 연결하여 제작으로부터 송출가지 통합관리가 가능한 새로운 방송 프로그램 제작환경, 이른바 멀티미디어 제작환경을 구축하는 것이 디지털 방송 시대의 방송 사업자에게 가장 중요한 과제중의 하나가 되었다. 멀티미디어 제작환경을 구축함으로써 영상, 음성 및 다양한 부가 데이터를 포함하는 멀티미디어 프로그램을 편리하게 제작할 수 있으며, 데이터베이스로부터 필요한 영상 이미지를 자유롭게 합성, 조작하는 등, 매우 다양하고 편리한 제작기법을 활용할 수 있다. 또한 멀티미디어를 응용한 제작 분야로서 컴퓨터 그래픽스 기술은 방송의 사전제작에 커다란 기여를 하고 있으며, 이미 선거방송을 비롯한 여러가지 프로그램은 가상스튜디오와 가상캐릭터 기술을 활용하여 제작하고 있다. 방송사업자는 이러한 멀티미디어 제작시스템을 근간으로 영상검색, 영상 합성, 스크립트 편집, 가상현실 응용 등 고도의 제작 기법을 활용함으로써 사용자 친화성, 다이나믹한 표현, 실시간, 대화성을 특징으로 하는 다양한 멀티미디어 서비스를 시청자에게 제공할 수 있을 것이다.

There were two purpose of this study. One was to develope a digital library as a way of facilitating students\` learning. The other was to design a model of a digital library for school. For this, current Korean educational information network plan and the problems of school libraries were analyzed first. Second, the role of school library was identified: to build a self-motivated learning environment in an information society and to help students developing creative learning abilities. Finally, a model of digital school library was suggested.

As one of the key competencies required in the era of the Fourth Industrial Revolution, interest and importance of digital competency is the growing. Digital competency means the ability to search and analyze necessary information using digital technology through collaboration and communication with other people to solve problems given in digital society and to produce the result. In this study, we will consider what factors should be included in the digital competence required in the era of the Fourth Industrial Revolution. To do this, we systematically classify factors that are considered to be important through analysis of relevant research on domestic and foreign digital literacy, and propose a digital competence model suitable for domestic reality based on this classification. In order to design a digital competence model, we first define the operational factors of the digital competence and then define and refine it by experts.

This study examines the factors that influence the mobile social participation of elderly disabled people compared to that of young adults with disabilities. The analysis was conducted using Heckman's two-stage model. The first stage of the research focused on the populations who have mobile devices, while the second stage focused on factors that influence mobile social participation. The results of the study are as follows: for elderly people with disabilities, mobile social participation is associated with living alone, PC usage ability, mobile usage ability, internet usage ability, and attitude towards digital use. Based on the results of this research, this study presents a plan to support the mobile social participation of elderly people with disabilities.

This research reviews the concept of Visual Literacy which is the critical base for performing convergence-style educational program of fine arts. The Visual Literacy means the ability to understand and properly deal with the visual information given to the agent such as the literacy to the written language. It is beyond doubt that the necessity of the Visual Literacy is raised because there is different visual information through new media for the entire life of young generation. Therefore, the Visual Literacy is the base for performing convergence-style education when it comes to performing convergence-style educational programs. It covers the communication abilities to utilize new media and exchange visual information one another.

The use of digital information technology has become important in order to effectively respond to changes in production conditions in Korean agriculture, which are continuously worsening due to a decrease in the rural population, deepening aging, and climate change. Accordingly, this study analyzed the factors affecting farmers' adoption of information devices use and the effect of information devices use on agricultural product sales using the propensity score matching method. As a result of the analysis, it was found that low-age farmers, high-education farmers, and leading farmers are highly likely to adopt use of information devices. For farms with similar characteristics such as age, management size, and farming type, it has been confirmed that farms that have adopted information devices use in agricultural management have higher sales of agricultural products. Therefore, increasing farmers' access to information and the ability to use information devices provides implications that farm income can be improved. The government's informatization support project in the agricultural and rural sectors is important so that farmers can have the ability to distribute informatization devices and utilize agricultural information, and active investment should also be made in information infrastructure.
