This study aims to understand the information needs and behaviors of university members given the societal shifts incited by the fourth industrial revolution as well as the changes in university research and education. We first conducted several in-depth interviews with diverse university members, and then adopted interpretative phenomenological analysis(IPA) to search the university members' information needs and behaviors including the contexts for such needs. The interviewees demonstrated more complex and convergent information needs than traditional information needs. They had very individualized information needs according their particular situations and took integrated problem-solving methods through their personal networks and/or making their own communities. When the interviewees' information needs were not satisfied by libraries, they tended to show low awareness of the libraries.

Smart work has been gaining more popularity recently. Smart work means that employees perform their works anytime and anywhere as utilizing the information and communication technology. It can be divided into four categories; the mobile office, the home office, the work-at-center and the tele-cooperation. Among them, the mobile office based on tablet personal computers(PCs) or smart phones, employees can exchange information with tablet PCs or smart phones via mobile radio communication networks and portable terminals. Smart devices such as tablet PCs and smart phones help to access intranet system for requests, approvals, information search whenever employees need. This mobile office system for real-time HSE managing can contribute to improve the productivity and work efficiency in a shipyard. In this study, the main goal is to design the specialized mobile application for the HSE management system on the shipbuilding industry. The mobile application including 10 functions is designed based on ooCBD(object-oriented Component Based Development) methodology.

Recently, software education has been emphasized as a key element of the fourth industrial revolution. Many universities are strengthening the software education for all students according to the needs of the times. The use of online content is an effective way to introduce SW education for all students. However, the provision of uniform online contents has limitations in that it does not consider individual characteristics(major, sw interest, comprehension, interests, etc.) of students. In this study, we propose a recommendation method that utilizes the directional similarity between contents in the boolean view history data environment. We propose a new item-based recommendation formula that uses the confidence value of association rule analysis as the similarity level and apply it to the data of domestic paid contents site. Experimental results show that the recommendation accuracy is improved than when using the traditional collaborative recommendation using cosine or jaccard for similarity measurements.

Since the 1990s, the role of the government has been shifting towards governance. This new governance emphasizes government's role in establishing a cooperative system with private organizations through network structure and interaction. In the 1990s, Korean Government support for artists and exhibitions increased unprecedentedly. In the 2000s, support for the arts shifted in ways so as to integrate genres. Simultaneously, in order to strengthen the creative capacities of artists, support for new artists, multi-art and fusion arts have increased. From 2010, 'visual arts' business support was provided. In addition, 'visual arts' was supported by a joint planning project from 2013 Also, an overseas residence program has actively supported exhibitions through international exchanges. Since 2005, it has expanded to cooperation with India, Iran and Asian countries as well as with the Betani Studio in Germany. In addition local government supported for artists and the Biennale, residences, regional cooperative business through the local cultural foundation.

This study introduces an innovative approach to monitor the whereabouts of workers within indoor construction settings. While traditional modalities such as GPS and NTRIP have demonstrated efficacy for outdoor localizations, their precision dwindles in indoor environments. In response, this research advocates for the adoption of Aruco markers. Leveraging computer vision technology, these markers facilitate the quantification of the distance between a worker and the marker, subsequently pinpointing the worker's instantaneous location with heightened accuracy. The methodology's efficacy was rigorously evaluated in a real-world construction scenario. Parameters including system stability, the influence of lighting conditions, the extremity of measurable distances, and the breadth of recognition angles were methodically appraised. System stability was ascertained by maneuvering the camera at a uniform velocity, gauging its marker recognition prowess. The impact of varying luminosity on marker discernibility was scrutinized by modulating the ambient lighting. Furthermore, the camera's spatial movement ascertained both the upper threshold of distance until marker recognition waned and the maximal angle at which markers remained discernible.

As web service technologies are widely used, there have been many efforts to develop approaches for recommending appropriate web services to users in complex and dynamic service environments. In addition, for the effective development of service mashups, service recommender systems that are specialized for service composition have been developed. However, existing service recommender systems for service mashups are not effective at recommending services in a personalized manner that reflect developers' preferences. To deal with this issue, we propose an approach that recommends services based on the similarities between mashup developers who have developed similar service mashups. The proposed approach is then evaluated by using the mashup data retrieved from ProgrammableWeb. The evaluation results clearly show that the proposed approach is an effective way of improving service recommendations compared to the traditional user-based collaborative filtering algorithm.

This paper attempts to explore the use of social metadata in academic libraries. A total of 173 academic libraries were examined and analyzed. Various social metadata were reviewed, involved with users' participation and contribution. Error-reports, tagging, recommendations, ratings, reviews, comments, sharing, and community were identified that support selection, sharing and collaboration through social engagement. Suggestions drawn from the findings are offered to utilize social metadata in order to enhance users' contribution and interaction. It is hoped that this exploratory study will provide insight into the use of social metadata in academic libraries.

BPMN(Business Process Modeling Notation)은 BPMI(Business Process Management Initiative)에서 발표한 것으로서 비즈니스 프로세스 모델링을 위한 표준 표기법이다. BPMN은 표준 모델링 표기법 이므로 다른 모델링 표기법을 익히는데 사용되는 시간을 줄이며 IT 및 비즈니스 사용자들 간의 의사소통을 증진시킬 수 있다. 이에 대응하여 WfMC(The Workflow Management Coalition)는 XPDL 매핑작업을 시도하여 BPMN을 XPDL로 표현할 수 있도록 하였고, 그 결과 BPMN에 매핑시킨 XPDL2.0을 발표하였다. 본 논문에서 설계한 모델링 시스템은 표준 표기법인 BPMN을 통하여 모델링을 하고 그 결과를 국제 표준화 워크풀로우 정의 언어인 XPDL2.0으로 제공하는 워크플로우 모델링시스템을 제안하여 다른 워크플로우 시스템들과의 상호 호환성을 제공하는 것이며, 역할 기반의 모델링 방식으로 복잡한 모델링 작업을 단순화 시킬 수 있다. 즉, 워크플로우 모델링 기능에 실시간 그룹웨어 특성들을 통합하여, 한 차원 높은 수준의 모델링 환경제공을 통하여 기존의 워크플로우 시스템들이 지원하지 못 했던 워크플로우 모델링 협동 작업을 실시간으로 지원 할 수 있을 문만 아니라, 요즘과 같이 대형화와 복잡화 그리고 다양화의 특징을 갖는 조직들의 워크플로우 들에 대한 효율적인 분석 및 모델링 환경을 제공하기 위한 워크플로우 모델링 시스템을 제안한다.

번역 메모리(Translation Memory)는 오늘날 기계번역에 있어 통계기반 접근법이나 형태-통사적 접근법 모두에 있어 가장 중요한 요소로 평가되고 있다. 그러나 번역 메모리는 언어의 자질 및 각 용례를 통합적으로 관리해야 하며, 이를 기계가 자동으로 처리해주어야 하는 어려움이 있다. 최근에는 이러한 문제점을 해결하기 위해 다국적 기업을 중심으로 기계보조번역(Computer Aided Translation) 환경에 대한 연구가 활발히 이루어지고 있으나, 언어적인 특성 보다는 번역 메모리의 저장/대치적 측면에서 주요 연구가 이루어지고 있다. 이 논문에서는 번역 메모리 정보가 보다 높은 재사용성을 보이기 위해서는 다양한 언어자질값을 담을 수 있어야 한다고 보고, 이를 효율적으로 관리/구축할 수 있는 기계보조번역 워크벤치의 framework을 제시한다. 언어분석을 위한 대상언어로는 교역 및 기술 측면에서 영어, 일어, 중국어 다음으로 영향력이 높은 불어를 채택하며, 기존 기계보조번역 방식에 대한 고찰을 통해 개선된 번역 메모리 관리, 자동분석/번역 모듈 및 협업(collaboration) 방안에 대해 소개하고, 향후 발전방향에 대해 논의한다.

항만정보시스템의 기능과 항만유형과는 관련성이 있는 것일까? 본 연구에서는 선진항만들의 유형과 정보시스템 기능 분석을 통하여 관련성을 규명하고자 하였다. 항만들은 자산의소유와 운영의 주체에 따라 국유제, 공영자치제, 지방자치제(지방정부자치제) 및 사유제의 4가지로 유형으로 구분된다. 유형에 따른 항만들의 주요 활동도 달라진다. 국유제와 지방자치제의 경우는 행정처리 기능에 중점을 두고 있는 반면, 공영자치제와 사유제는 고객서비스강화에 중점을 두고 있다. 항만의 유형과 정보시스템과의 상관관계를 조사한 결과 국유제, 지방자치제 항만에는 업무처리 중심의 시스템이 발달하여 있으며, 사유제 및 공영자치제 항만에는 고객서비스를 최우선으로하는 커뮤니티 시스템과 e-Business 시스템이 발달되어 있었다. 항만유형별 정보시스템의 차이는 부산항만정보시스템의 개선에 시사점을 던져주고 있다. 그동안 국유제 항만으로서 운영되던 부산항이 공영자치제 유형의 운영방식으로 변경됨에 따라 항만정보시스템도 추세에 따라 개선되어야 한다. 본 연구에서 제안하는 방법으로 3단계 방법을 제안하였다. 제 1단계가 미러링(Mirroring) 단계로서 항만운영을 안정화시키는 단계이며, 제 2단계에서는 커뮤니티 시스템을 구축하여 고객의 서비스를 제고시키는 협업화단계로 설정하였으며, 제 3단계는 부가가치창출을 위한 수익형 시스템을 개발하는e-Business 개발단계로 설정하였다.
