Visual conservation center is a facility for the preservation of visual materials such as film and digital image data, and its construction project is currently being considered. This study evaluates the economic benefit of the project using CVM (Contingent Valuation Method), the main method of nonmarket evaluation in the both domestic and foreign literature. Survey data used in the analysis was collected in seven major metropolitan cities using person-to-person interviews and a logit model is used for the econometric estimation. The economic benefit measured by a household's average willing to pay (WTP) per year is shown to amount to 8,958 won.

From PC communication to the development of the internet, a new term has been coined on the social media, and the social media culture has been formed due to the spread of smart phones, and the newly coined word is becoming a culture. With the advent of social networking sites and smart phones serving as a bridge, the number of data has increased in real time. The use of new words can have many advantages, including the use of short sentences to solve the problems of various letter-limited messengers and reduce data. However, new words do not have a dictionary meaning and there are limitations and degradation of algorithms such as data mining. Therefore, in this paper, the opinion of the document is confirmed by collecting data through web crawling and extracting new words contained within the text data and establishing an emotional classification. The progress of the experiment is divided into three categories. First, a word collected by collecting a new word on the social media is subjected to learned of affirmative and negative. Next, to derive and verify emotional values using standard documents, TF-IDF is used to score noun sensibilities to enter the emotional values of the data. As with the new words, the classified emotional values are applied to verify that the emotions are classified in standard language documents. Finally, a combination of the newly coined words and standard emotional values is used to perform a comparative analysis of the technology of the instrument.

Electronic Medical Record(EMR) is medical record that has been saved electronically onto a computer. The standardization activities for EMR is actively underway as it may not only improve the overall quality of the medical services but as the value of medical big data (medical & IT convergence area) is being considered very important. One of the most important issues is ensuring the necessary and effectiveness of EMR standardization to the stakeholder. Researchers did an empirical study to find out how the doctors perceived the EMR standardization from both technical and economical perspective. The results of the empirical analyses showed that system quality and an economical value had a positive effect on perceived usefulness and intention to adopt EMR standardization, yet interoperability have only affected the perceived usefulness. Additionally, the economical value seemed to be the most important variable in forming a consensus in the need of EMR standardization.

Stream data is a continuous flow of information that mostly arrives as the form of an infinite rapid stream. Recently researchers show a great deal of interests in analyzing such data to obtain value added information. Here, we propose an efficient cube computation algorithm for multidimensional analysis of stream data. The fact that stream data arrives in an unsorted fashion and aggregation results can only be obtained after the last data item has been read. cube computation requires a tremendous amount of memory. In order to resolve such difficulties, we compute user selected aggregation fables only, and use a combination of an way and AVL trees as a temporary storage for aggregation tables. The proposed cube computation algorithm works even when main memory is not large enough to store all the aggregation tables during the computation. We showed that the proposed algorithm is practically fast enough by theoretical analysis and performance evaluation.

최근 들어 클라우드, 소셜네트워크, 빅데이터 등 보안시장에 영향을 미칠 수 있는 새로운 성장동력원이 등장하면서 정보보호산업이 급격히 진화하고 있다. 본고에서는 정보보호산업의 국내외 시장 전망과 주요국의 정보보호정책을 개관한 후, 최근 주요 선진국을 중심으로 이슈화되고 있는 IoT 정보보호 관련 법 규제 동향을 살펴보았다. 본 분석을 통하여 국내 정보보호산업을 육성하기 위해서는 제품시장도 중요하지만, 상대적으로 부가가치가 높은 서비스시장에 보다 중점을 둔 시장육성 전략이 요구된다는 점과 기존의 정보보호법을 사물인터넷에 적용하기 위한 대책을 서둘러야 한다는 시사점을 얻을 수 있었다.

최근 글로벌 OTT 서비스에서 한국드라마가 세계적 인기를 얻음에 따라 드라마 콘텐츠의 가치가 높아지고 있다. 드라마 대본은 드라마 제작에 있어서 핵심이 되는 데이터로, 특히 대사에는 인물의 특성이 잘 나타나 있다. 본 논문에서는 KoBERT 모델을 활용해 드라마 대사에서 인물의 특성 중 하나인 성별을 구분하고 실험 결과를 제시한다. KoBERT 모델로 대사의 성별을 분류한 뒤, 콘텐츠 분석과 인공지능 창작 측면에서의 활용 가능성에 대해 논의한다.

Industrial heritage resources produced by industrial activities have historical and conservative values and value as cultural properties as they serve as a medium connecting the past, present, and future. In other words, Industrial heritage resources should be used, managed, and preserved simultaneously as important records and evidence for the future. Metadata is well known as a necessary and important factor for the use, management, and preservation of information resources. In particular, in order to describe various industrial heritage resources that have historical, cultural, and conservative values, metadata elements from various perspectives are needed to relate to the story, type etc. of data. Therefore, this study attempted to design metadata elements that can comprehensively describe different types of industrial heritage resources. And we designed metadata that suited for the purpose of using, managing, and preserving industrial heritage resources, through mapping and combination between industrial heritage-related metadata. As a result, metadata was grouped into five types(administrative, descriptive, preservation, technical, use) and prepared into a total of 25 higher & 86 lower elements.

최근 과학 및 IT 패러다임은 HW(과거) 및 SW(현재) 중심에서 '데이터 빅뱅'을 활용하여 정치 사회 경제 등 제반 이슈와 연계된 분석 예측으로 진화 중이다. 국가안전 및 위험관리, 의료, 교육, 복지, 환경 등 사회 전반에 걸쳐 공공부문에서의 빅데이터 활용 가능성이 높아지고 있다. 공공정보 자체뿐만 아니라 민간정보와의 통합 분석을 통해 효과적인 맞춤형 정책과 새로운 지식정보 서비스 제공이 가능하기 때문에 주요 선진국은 공공정보의 적극 활용을 위해 다양한 정책을 경쟁적으로 추진해 오고 있다. 공공정보의 민간활용 촉진은 정보 제공자인 공공기관뿐만 아니라, 이를 활용하는 민간 사업자, 관련 서비스 사용자 모두에게 경제적 비경제적 가치를 제공할 수 있다. 따라서, 본 연구를 통해 국내 공공정보 민간활용 산업의 경제적 파급효과를 추정하고, 중요한 전 후방 연결 산업들을 파악하고자 한다.

유선과 무선으로 구분되어 있는 망, 기술, 사업, 서비스 등의 통합, 방송과 통신, 정보통신의 융합이 함께 복합적으로 일어나는 것이 산업계 현상의 하나이다. 현재 유무선 통합에 따른 인터넷 환경이 계속 발전되고 있다. 하지만 유무선 컨텐츠에 대한 일관된 분류체계의 부재로 인하여, 기업간, 나라간, 유무선 통합 컨텐츠 비즈니스의 수행에 대한 종합적인 분석이 불가능하다. 이러한 이유로, 유무선 통합 서비스에서 제공되는 다양한 컨텐츠에 대하여 종합적인 분석을 할 수 있는 자료가 필요하다. 이러한 자료를 도출하기 위해서 본 논문은 유무선 컨텐츠를 통합 관리하는 방안으로 분류체계, 식별체계, 속성체계 및 관리 프로세스를 정립 설계하는 방법으로 유무선 컨텐츠 각각에 대한 적시적이고 폭넓은 분석수행이 가능하고, 고객과 사업자에게 일관된 가치를 제공할 수 있다. 따라서 유무선 통합 컨텐츠 메타테이터를 설계하는 것으로 유무선 컨텐츠 관리가 곧 메타데이터 관리가 되게끔 하는 것이다.
