To search based on the functional classification or provenance is not easy for users, and the key word-based information retrieval presents only simple words matching with the title of the records. The Presidential Archive of Korea developed a subject classification scheme to improve the convenience of searching for various records and came up with a subject thesaurus based on the scheme that utilizes the terms appearing on the title of the records and the terms used by the users who searched the portal or requested information disclosure. This research presents the development process of subject thesaurus. It also presents the utilization methods for records management work and services.

Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

The purpose of this study was to explore the lonely-death phenomenon and to understand the circumstances surrounding the lonely-death cases among elderly people by examining the articles on such phenomenon and the media reports of such cases. The cases of lonely death reported from 2007 to 2017 were used. Case analysis was conducted, and the news articles that described the lonely death cases were identified using an internet search engine. Forty seven cases were analyzed. Several risk factors emerged from the data obtained, such as economic hardship, chronic illness, mental health problems like alcohol addiction, social isolation, disconnection from family members or the neighborhood, unemployment, single household, unmarried or divorced status, and living in an urban area. Based on the findings, prevention strategies were addressed.

본 사례연구는 한국정보사회진흥원에서 개발한 디지털콘텐츠의 표준식별체계인 UCI(Universal Content Identifier)를 (주)누리미디어 보유의 약33만 건 콘텐츠에 적용한 사례와 비즈니스 모델을 소개하고 있다. UCI란 '디지털콘텐츠의 유통활성화' 를 이룩하기 위한 목적으로 도입하는 기술로 개별 디지털콘텐츠에 식별기호를 부여하는 기술이다. 본 사업은 UCI코드 체계를 이용하여 콘텐츠 관리 시스템을 구축하는 것을 목표로 하고 있다. UCI-RA시스템 구축이후 기대효과로는 콘텐츠 제공과 관련된 업무에 인적, 물적 비용을 절감하고, 신규 콘텐츠 발굴 및 개발이 용이하도록 하였다. 또한 서비스 운영과정에서는 기 확보된 콘텐츠를 비즈니스화 하여 신규 수익창출의 모델로 육성할 수 있다. 한편 콘텐츠 소비과정에서는 콘텐츠 검색의 용이성 및 구매 용이성 증대를 통해 양질의 콘텐츠를 유통하는 것이다. 아울러 운영기업의 콘텐츠 등록 및 운영과정에서의 유료콘텐츠 정산주기율 단축, 콘텐츠 품질 고객만족도 제고 등의 효율성을 증가할 수 있다.

최근에 인터넷을 통한 전자경매가 보편화되면서 경매 물품의 가격 결정에 대한 관심이 증가하고 있다. 또한, 경매물품의 낙찰가를 판매자가 결정하거나 정보 검색이론의 사례 유사도에 기초하여 생성하는 에이전트가 연구되고 있다. 그러나, 이것은 경매 물품에 대한 최근의 변화 요인을 반영하지 못하고, 상품 추천에서 사용하는 사례 유사도를 가격 결정에 적용하여 잘못된 가격이 생성되는 경우가 많다. 본 논문에서는 이러한 문제점을 해결하고자 시계열 예측에서 사용하는 지수평활법을 이용하여 최근의 경매자료로부터 경매 등륵 물품의 낙찰 예정가를 자동으로 생성하는 시스템을 제안한다. 성능 실험 결과, 본 시스템을 사용할 경우에 경매 물품의 실제 낙찰가와 차이를 줄여 낙찰률을 높이고, 경매 물품의 객관적인 가격형성이 가능함을 보인다. 또한 기존의 사례 유사도를 이용한 낙찰 예정가 생성 방식과의 성능 비교를 통하여 새로운 방법의 효율성을 나타낸다.

본 연구에서는 귀농 귀촌인들이 성공적인 정착을 할 수 있는 계기를 마련하고자 '소셜미디어' 활용 사례를 연구하였다. 연구를 위해 귀농 귀촌 현상을 살펴보고 소셜미디어의 중요성을 알아보았다. 귀농 귀촌인 대상을 선정하여 인터뷰를 진행하였으며 필립코틀러의 마켓4.0의 5가지 마켓경로(인지, 호감, 질문, 행동, 옹호)와의 연관성을 사례분석을 통해 살펴보았다. 연구결과로 첫째, 귀농 귀촌인이 직접 재배하는 친환경 농산물을 성공적으로 판매할 수 있었던 주요 원인은 다음과 같다. 첫째, 소셜미디어를 적극적으로 활용했다. 둘째, 계절마다 농산물을 재배하고 수확하는 과정을 체험할 수 있는 프로그램을 운영하여 농산물에 대한 만족도를 높였다. 셋째, 현장체험 및 농산물의 사용 후기, 가격 등을 다양한 채널에서 검색을 가능하게 했으며 각 채널마다 고객과의 소통을 원활하게 했다. 넷째, 소셜미디어 운영에 있어 지속적으로 새로운 콘텐츠를 노출하여 연속적인 구매활동을 유도했다. 다섯째, 구매 후기를 활용하여 재구매를 유도했다.

With the recent expansion of internet shopping mall, the importance of intelligent products recommendation agents has been increasing. for the products recommendation, This paper propose case-based reasoning approach, and developed a case-based bundle products recommendation system which can recommend a set of sea food used in family events. To apply CBR approach to the bundle products recommendation, it requires the following 4R steps : \circled1 Retrieval, \circled2 Reuse, \circled3 Revise, \circled4 Retain. To retrieve similar cases from the case-base efficiently, case representation scheme is most important. This paper used OW(Object Modeling Technique) to represent bundle products recommendation cases, and developed a similarity measure method to search similar cases. To measure similarity, we used weight-sum approach basically. Especially This paper propose the meaning and uses of taxonomies for representing case features.

Research and development projects in railroad domain are different from those in other domains in terms of their close relationship with laws. Some cases are reported that new technologies from R&D projects could not be industrialized because of relevant laws restricting them. This problem comes from the fact that researchers don't know exactly what laws can affect the result of R&D projects. To deal with this problem, we suggest a model for law retrieval system that can be used by researchers of railroad R&D projects to find related legislation. Input of this system is a research plan describing the main contents of projects. After laws related to the R&D project is provided with their rankings, which are assigned by scores we developed. A ranking of a law means its order of priority to be checked. By using this system, researchers can search the laws that may affect R&D projects throughout all the stages of project cycle. So, using our system model, researchers can get a list of laws to be considered before the project they participate ends. As a result, they can adjust their project direction by checking the law list, avoiding their elaborate projects being useless.

In order to encourage construction practitioners to acknowledge failures and disseminate the information, the failure information must be documented and accumulated with a well-structured format, which contains not only the fact and result but also the circumstance and cause of the failure. In the Korean construction industry, many failures are not explained clearly and often not even reported publicly, partly because due to the lack of understanding positive aspects of failures, which can improve construction practices as a result of learning from failures. The purpose of this study is to develop a web-based construction failure information system using the case-based reasoning techniques, which can systematically accumulate, manage, and share the valuable failure information using a structured failure cases database. It can be utilized for planning proactive solutions on future failures by searching the very similar past failure cases.
