This paper introduces a new concept to analyze the digital control system where the continuous-time plant is stabilized by the digital controller with sampler and hodl. It gives some methods to handle the inter-sampling behavior which has not been considered in the digital controller design. Also, the new trend and future direction in digital control are introduced.

With science and technology getting more and more advanced, the scope of digital product is expanding and the new products continuously are introduced on the market. On the basis of consumers' attachment to products, we investigated the consumers' behaviors towards the product when a digital product is extended. As a result of an empirical analysis, it turned out that a consumer tended to have higher trust and a positive emotion about relevant goods if he or she had a strong attachment to digital products. However, even though one had a strong attachment to digital products, the emotion about the corresponding brands did not necessarily appeared to be positive. In the event that a brand of digital products was extended to other new products, only the trust in the brand exerted significant influence on the consumers' behaviors towards the extended products. Finally, this study suggests some theoretical and managerial implications for effective strategies in response to customers' attachment to digital product.

Digital Manufacturing is a technology facilitating effective developments and agile productions of the product via digital computer models representing physical and logical schema and the behavior of the real manufacturing systems including manufacturing resources, environments and products. For the successful application of this technology, a digital factory as a well-designed and an integrated environment is essential. In this paper, we constructed the sophisticated digital factory of a Korean automotive company's body shop, and conducted precise simulations of unit cell, lines and the whole factory for the collision check, the production flow analysis and the off-line programming. We expect that this digital factory of the body shop helps us achieve great savings in time and cost for many manufacturing preparation activities of the new car development.

Digital content industry is growing rapidly because of the property of high-speed networking and greater demand for digital fulltext-image. However, we know the fact that it is many difficulty in production and supply for good quality of content. Hereupon, we suggest digital fulltext-image service framework to protect copyright. More concretely, we propose integrated model and reference model to securely serve digital fulltext-image by recompositing core objects and reconstructing the value-chain structure of digital content industry to framework including the process(from its production (creators or copyrighters) to consumption (users or consumers)). Also, we construct the digital fulltext- image service system based on reference model and reconstruct its interface that occurs between core subjects.

The objectives of this study are to provide advices and methods for cultivating labor in the digital cultural contents industry in the Chung-Nam Province. For the purpose of this study, review of theoretical and practical literature, identifying the present status of affairs, and three times FGI and surveys were executed. The results of research show a lack of professional labor in the digital cultural contents industry; even so most of laborers want to get a job in or around the Seoul region. To activate digital cultural contents in the local area, a development model for the Chung-Nam digital cultural contents industry was introduced and four strategies were also suggested. The nurture of a professional skilled labor force through a strategically designed joint relationship between university and companies in the digital cultural contents industry was found to be quite necessary. In this way, the need for specialized training and education in the university classroom can be supported.

Accesses to lands, houses, the Internet and other utilities are regarded as basic human needs to escape poverty and are required to recognize the relationships between the digital divide and socio-economical inequality. The digital divide might not be a single technical disparity, but stems from a complicated mixture of economic and socio-technical symptoms of inequality. There is growing awareness of scrutinizing causal mechanisms between the digital divide and poverty since combating poverty could be a primary step to mitigate the digital divide. In this paper, the Hexad model is proposed to explicate poverty interpretation by using 6 parameters as a major tool for partly assisting in poverty monitoring system in connection with land information. A solution model of the Internet is suggested to break the digital divide. It expounds a conceptual framework and new idea for poverty management to notify spatio-temporal locations of poor actors and geography of the digital divide when efforts of poverty eradication hinge on understandings of geographic location of digital disadvantaged groups through parcel-based land information.

Recently, with the enlargement of cloud computing, virtual desktop infrastructure(VDI) can be an alternative of the existing personal computer based information environment. For the case of partially introduced VDI coexisting with personal computer environment, we suggest a virtual folder based approach to control the overall digital contents within an organization with a case of implementation. Although a centralizing device was used for storage and sharing of organization's digital contents, it was not easy to accomplish centralizing digital contents completely. It is tried to prevent users from utilizing their own storage in their personal computers or virtual machines and to use virtual folder which transfer and store digital contents to and in EDMS. The virtual folder system of this paper looks like a real folder in a personal computer, but it is another virtual device for outer storage devices including EDMS. It can be an alternative and reference of digital contents control for future applications of cloud computing.

As society becomes more digital, the need for digital forensics experts are gradually increasing. It is necessary to establish a training policy that reflects the special characteristics of digital forensics personnel. Although there are fragmented policies for digital forensics-related systems and human resources training in academia, it is an urgently necessary to establish a systematic and long-term policy to foster digital forensics experts. This study suggests curriculum of digital forensic based on the importance ranking among forensic subjects. The importance ranking can be decided by forensic experts. This study can be used as policy data to foster diverse talent that can effectively meet the increasing demand for digital forensics talent. The systematic curriculum proposed in this study is a practical curriculum at the undergraduate level and can be suitable for university level

본 연구는 디지털 격차가 노인의 디지털 일상생활에 미치는 영향력을 분석하는 것이다. 60세이상의 노년층을 대상으로 디지털 격차에 대한 적응경향성을 측정하여 집단으로 구분하였고, 디지털 의사소통 기술, 디지털 자신감, 디지털 자기통제감, 디지털 생활만족을 측정하였다. 연구모형은 교차설계 모형과 이중매개모형을 적용하였다. 연구결과, 첫째, 디지털 격차에 대한 적응 접근성이 높은 집단이 전반적인 디지털 일상생활에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 디지털 격차에 대한 적응 활동성이 높은 집단이 디지털 자기통제감에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 디지털 의사소통 기술이 디지털 생활만족에 긍정적인 영향을 미치며, 디지털 자신감과 디지털 자기통제감은 매개역할을 하는 것으로 나타났다. 이러한 연구결과를 토대로 노년층의 디지털 격차에 대한 극복 전략에 대해 논의하였다.

수치사진측량은 1960년대 처음으로 도입되었지만 당시 컴퓨터 및 수치영상처리 기술의 한계로 발달할 수 없었다. 그러나 최근에는 컴퓨터기술과 영상처리 기술의 발달에 힘입어 사진측량분야에서 그 영역을 구축하기 시작했다 또한 인공위성과 CCD카메라, 사진의 수치정사(스캐닝)등에 의해 대량의 수치데이타를 얻을 수 있게 됨으로써 수치사진측량에 관한 많은 연구가 이루어지고 있다. 전통적 인 사진측량과 수치사진측량은 초기의 입력데이타(아날로그/수치)에 따라 확연히 구분된다. 즉 수치사진측량은 컴퓨터를 이용하여 수치영상처리의 완전자동화가 가능하다. 그러나 수치사진측량은 아직 걸음마 단계이고 실제로 이론과 기술에 대한 이해부족으로 해결해야 할 문제가 많다. 효율적인 수치지도제작과 경제적인 GIS 데이타베이스구축에 대한 수요가 점차 증가하고 있는 현실을 감안할때, GIS와 수치사진측량기법의 연계는 필연적이다 이 논문에서는 수치 영상과 수치사진측량 워크스테이션 등 수치사진측량의 현재수준과 GIS에서 수치사진측량의 역할에 대해서 논의 하였다.
