The pig ICT automatic feeder is capable of automatically feeding feed, etc. according to the set conditions. However, there is a disadvantage that the setting condition itself must depend on the user's experience. Therefore, trial and error is caused, and there is a problem that the efficiency is lowered. Therefore, it is necessary to develop a system and implement a service model that can improve pig productivity by suggesting optimal feeding setting conditions based on data. Therefore, in this paper, a pig feeding management service model was developed using the performance analysis program such as the existing feeding data, breeding management data, and pig production management system. Through this, we developed a consumer-oriented feed management service model that can be efficiently utilized by analyzing pig data. In addition, it is possible to provide a service that contributes to a decrease in the mortality rate and an increase in the MSY of the farms with the intelligent automatic feeding management service, thereby improving the productivity of the pig farms and thereby increasing the income of the pig farms.

In recent years, many institutions predict that cloud services and big data will be popular IT trends in the near future. A number of leading IT vendors are focusing on practical solutions and services for cloud and big data. In addition, cloud has the advantage of unrestricted in selecting resources for business model based on a variety of internet-based technologies which is the reason that provisioning and virtualization technologies for active resource expansion has been attracting attention as a leading technology above all the other technologies. Big data took data prediction model to another level by providing the base for the analysis of unstructured data that could not have been analyzed in the past. Since what cloud services and big data have in common is the services and analysis based on mass amount of data, efficient operation and designing of mass data has become a critical issue from the early stage of development. Thus, in this paper, I would like to establish data processing architecture based on technological requirements of mass data for cloud and big data services. Particularly, I would like to introduce requirements that must be met in order for distributed file system to engage in cloud computing, and efficient compression technology requirements of mass data for big data and cloud computing in terms of cost-saving, as well as technological requirements of open-source-based system such as Hadoop eco system distributed file system and memory database that are available in cloud computing.

In this study, we suggest the effective storage structure and management method for XML-based electrocardiography(ECG) data to support the interoperability between medical information systems, and implement the metadata system of ECG data providing the web-based information service. ECG matadata management system include functions for storing and managing as well as reporting PDF service of ECG data. We analyzed a characteristics of the data and access patterns for XML-based ECG and then used the non-partitioning storing method and indexing the extracted metadata from the HL7 aECC for supporting the quick search. We, using the template mechanism, converts the XML-based results data into various formats in order to provide services of the ECG reporting.

This paper suggests producer/consumer-based Data Binder enabling applications and biomedical devices developed by mutually different vendors to transfer data dynamically. Data Binder is implemented as a bundle of OSGi platform providing component-based programming model and service-oriented operation architecture. Data Binder complements the disadvantage of OSGi WireAdmin service enabling static data delivery between a producer and a consumer of data. Data Binder normalizes an application requirement as an application descriptor and a device capability as a device descriptor so that it enables dynamic data delivery by making data producer/consumer pair in runtime. Therefore, Data Binder can be used as a connection management of a data link between a data producer and a data consumer in sensor-based application development. The object of this paper is to provide the facility of the healthcare service development by separating a data producer such as a biomedical device from a data consumer such as a healthcare application.

We are living in big data. Specially, female consumers are the hottest issue. Female consumers have a great effected on consumer culture as comparing male consumers. Therefore, this study analysis characteristics of female consumers through case study and literature review. The summarized results of research are as follows. First, percentage of economically active population of unmarried female of 20s is high, so they actively spend lots of money on buying goods and so on. Second, they are ahead of the curve and follow entertainers. Third, domestic case studies(SD online buz marketing, C.S.I. Shinsegaemall project, Service center only for female consumers of Shinhan Card, Travel Service of Lotte Tour) and international case studies(Big data service of Target, ZARA, and Walmart) show that if we utilize big data, we can raise re-purchasing desire and analysis needs of female consumers and create new female consumers.

This study revisits issues for Big data. Three research questions, understanding the concept of Big data, important issues of Big data research and utilization methods for library information services, are explored by the literature and practice reviews. Study results revealed several important issues of Big data including the concept in the context of real world situation, the problems with the accuracy and reliability of the data, privacy and ethical issues, and issues of intellectual property rights. With understanding these issues, a few utilization methods were introduced for Library and Information services. It was included using its analysis for developing vision, adopting Library management, supporting community services, and providing customized information services for various users. The study concluded Big data analysis would effectively provide valid evidences for all those services.

N-Data Center which provide of cloud computing service for the Government departments, will be prepared transforming to cloud data center and transformed into an 'IT service' provided as a service to the information resources required by each department. N-Data center already provide a cloud service to the departments as maintains a high level of security, and plan to connecting with the private sector as a precondition of security. Therefore, in order to promote them effectively, it is necessary to determine the level of security in the cloud data center, and we have proposed appropriate measures. In this paper, we analyze security requirements of cloud data centers in developed countries and identify the leading private cloud data center security. In addition, we identify the N-data center security level, and analyzes the data center and private cloud gap and provide a transition strategy in terms of security finally.

최근 미디어 간 컨버전스가 가속화되면서 그 사이를 흐르는 콘텐츠 유형이 방송과 인터넷 양쪽을 충족시키고 또한 모바일 환경에 최적화된 서비스를 위해 클립화 되어 가고 있다. 다수의 미디어 콘텐츠를 공급하는 방송사의 입장에서는 콘텐츠서비스를 위한 콘텐츠 관리방안이 중요한 이슈가 되고 있으며 ID, 메타데이터 등 관리를 위한 체계를 잡는 것의 중요성도 증대되고 있으며 또한 분절된 동영상을 어떻게 만들고 어떻게 서비스 할것인가도 중요한 이슈이다. 이번연구는 대표적인 방송용 콘텐츠 메타데이터 표준인 EBU Core, PB Core와 우리나라 KBS 메타데이터의 분절형동영상 관련하여 메타데이터 구조를 파악하고 어떻게 구성되어 있는지 비교분석하여 보았다. 분석결과 메타데이터가 근간을 이루는 기본구조는 거의 유사하였고 각각 관점의 차이에 따라 추가되는 항목이 존재함을 발견할 수 있었다. 그리고 최근 미디어 환경변화에 따라 분절형동영상을 표현하는 메타데이터 항목에 대한 개선방향을 몇가지 제안하였다.

디지털 경제에서는 세계표준을 따르는 것이 선택이 아니라, 필수적인 것이다. 따라서 디지털 방송표준또한 필연적으로 준수되어져야 하는 규격인 것이다. 최근 방송환경이 매체별(지상파, 위성, 케이블)로 디지털방송으로 전환 중이거나 전환을 완료하여 서비스중에있다. 데이터방송 또한 매체별로 실험서비스 혹은 본방송이 진행중이다. 데이터방송은 디지털 방송에 양방향 서비스를 가늠하게 하는 개념으로서 국내의 지상파 데이터방송 표준 규격이 ATSC (Advanced Television Systems Committee)-DASE (DTV Application Software Environment), 위성의 경우 DVB MHP (Digital Video Broadcasting - Multimedia Home Platform), 케이블은 OpenCable-OCAP(OpenCable Common Application Platform)으로 결정되었다. 이와 같이 국내에서 채택하고있는 데이터방송 규격은 매체별로 서로다른 규격을 따르고있으며 규격 표준화 진행은 완료되었거나 진행중에 있다. 따라서 본 고에서는 지상파, 위성, 케이블 데이터방송 표준동향과 매체별 데이터방송 표준 규격에 대해 살펴보고자 한다.
