  • 협업은 둘 이상의 사람들이 하나의 업무 또는 목적을 달성하기위해 공동으로 협력하여 일하는 것이다. 최근 개인 및 조직 간 협업 범위가 공동분석, 데이터 연계, 서비스 조합 등으로 확장되고 대용량 데이터 공유 및 실시간 연계분석 활동이 증대되면서 협업 지향적인 시스템 설계와 개발이 중요시 되고 있다. 특히 스마트워크와 지능화된 협업 기반은 데이터, 프로세스, 서비스, 사람 간의 다차원 연계와 실시간 활용, 의미 기반의 기계적 협력을 전재로 하고 있다. 본 연구에서는 Data, Process, Service, People 측면의 4가지 계층으로 전사적 자원을 설계하고 메타 메타데이터 기반의 온톨로지 분석을 통해 자원 간의 연계와 조합을 지원하는 시스템을 설계했다. Data 계층은 프로세스별 Input, Output 정보를 식별하여 Data의 메타 정보를 정의하고 이를 검색 에이전트가 색인하여 모델링에 참조할수록 한다. Process 계층은 BPMN모델을 확장한 exCPM의 개선 모델을 바탕으로 프로세스를 수행주체 간, 정보공유측면에서 프로세스를 분석했다. Service 계층은 협업지향적인 프로세스를 구성하는 컴포넌트를 서비스로 인식하고 프로파일을 통해 협업을 위한 검색과 프로세스를 연계지원하도록 설계 했다. 마지막으로 People계층은 자원, 프로세스, 서비스 등 시스템에 관여하는 참여자들의 메타정보를 정의하고 이를 온톨로지 기반의 모델에 통합하여 자동 검색되도록 설계했다. 이를 통해 프로세스와 서비스 측면에서 협업을 요구하는 에이전트와 일반 검색 사용자들이 프로세스 간 협업 자원을 파악하고 상호 관계를 분석할 수 있도록 하는 한편, 프로세스를 지원하는 컴포넌트와 서비스 간의 자동적인 조합을 통해 통합적 자원 협력과 실시간 협업 지원 기반을 제시했다.

  • In this paper, the fire extinguisher maintenance system using smart NFC communication and the real-time pressure measurement is proposed. The proposed system consists of three steps in the flow of information. The first step is to identify the fire extinguisher through NFC tagging in the fire extinguisher module using the smart device. The fire extinguisher appearance check and the real-time pressure measurement is performed in the second step, and the last step sends the check status information to the management server. In particular, the actual pressure value is calculated based on the angle of the green area and the indicating needle. Some experiments are conducted so as to verify the proposed system, and as a result, the proposed system shows that the administrator can effectively control the status information of fire safety check.

  • 평화를 전쟁의 부재라고 정의할 때 현재 전쟁이 없다면 지금 이 시간은 안전하고 평화로워야 한다. 그러나 지금 현 세상은 비록 공식적으로 선포된 전쟁은 없다고는 하지만 그래도 결코 평화롭다곤 할 수 없을 것이다. 흑해의 크림반도가 노골적인 군사적 침략이 없었지만 결과적으로 러시아의 수중에 떨어졌다. 남중국해의 여러 섬이나 암초들이 정규 군사작전 없이 사실상의 중국의 소유로 기정사실화 되고 있다. 전시 군사적 침략을 통해서만이 확보 가능한 전략적 목표들이 전시도 아니고 그렇다고 평시도 아닌 어중간한 시기에 적 또는 상대의 수중에 떨어지고 있다. 즉, 전시와 평시 사이의 회색지대에서 소위 회색지대전략이라고 부르는 공세적 전역을 통해 이러한 전략적 목표들이 달성되어 지고 있다. 소시지가 너무 커 한입에 다 먹을 수 없으면 잘게 썰어 하나씩 먹으면 결국 전체를 다 먹을 수 있듯이 소규모의 절차적 행동을 단계적으로 실행, 대규모 전투를 통해서만이 확보 가능한 거대하고 중대한 목표를 확보하는 게 회색지대전략의 한 특징이다. 이를 전략적 점진주의(strategic gradualism)라고 한다. 또한 단계적 행동은 누구나 인지할 수 있지만 그러한 점진적 행동의 결과에 대해선 쉽게 간파할 수 없기 때문에 대응자의 입장에선 대부분 특별한 대응책을 세우지 못하고 방치하고 만다는 게 이 전략의 또 다른 특성이다. 즉, 회색지대전략은 특성상 반드시 애매모호성(ambiguity)을 띄고 있다는 것이다. 회색지대에서의 도전자의 행위는 일종의 속임수일 수도 있다. 전략의 본질은 위계, 즉 상대로 하여금 오인, 착각, 부지를 일으키도록 하여 소기의 목적을 달성하는 것이다. 그래서 회색지대전략(gray zone strategy)이라고도 한다. 양육강식의 논리가 작용되는 현실 세계에선 힘이 곧 정의이고 국익이 최고의 선이다. 국가이익은 오직 과정보다는 결과만을 놓고서 정당화된다. 이에 회색지대전략에서도 결과에 대한 유용성만 거론되지 과정상 불법성이나 비도덕성 등은 따지지 않는다. 대부분 이 전략의 애매모호성 때문에 과정 자체를 식별하기가 쉽지 않다. 그래서 대응자의 입장에서도 사전에 예방할 수 있는 선제적 대응전략을 구사하기가 어려운 게 사실이다. 한국도 예외가 아니다. 중국이 해상민병을 이용한 회색지대전략을 구사, 이어도에 대한 도발을 감행할 수도 있다. 일본이 민간 극우파 등을 이용한 회색지대 전략을 구사, 독도에 대한 도발을 감행할 수도 있다. 평화는 거저 존재하지 않는다. 확전을 각오한 사전대비차원의 억지책이 마련되어야 상대의 회색지대전략을 단념시킬 수 있다. 그것도 신뢰성 있는 억지력만이 진정한 평화를 담보할 수 있다. 전략이 있어야 대응계획을 세울 수 있고, 상대는 이럴 때 도발을 단념하게 된다. 대응전략이 없다는 것은 대응계획이 없다는 것을 의미하고, 이러한 무계획은 늘 실패만을 계획하고 있다는 것을 명심해야 할 것이다.

  • The aim of this study is to propose the introduction of narrative description as an improvement to describing archives, thereby enhancing the user experience of archives. To achieve this, the study identifies the specific forms and positions of narrative elements in archives and analyzes the interaction between archival description and narrative elements. It also examines cases where narrative description has been applied in digital archives to analyze their purposes and identify the various types and characteristics of narrative description for the improvement of description and considering factors that should be taken into account when implementing narrative descriptions. Theoretical research explores the concept and role of narrative and analyzes how it is manifested in describing archives. Case studies investigate the types of narrative description in digital archives and explore their roles. Narrative description emphasizes that it can facilitate implementation by establishing the narrative identity of archivists as context constructors, conducting extensive and deep research on records, and planning collaborations with experts. However, due to the lack of concrete implementation plans for narrative description in the practical archives, further research is needed to develop models of narrative description and prepare various examples of narrative applications.

  • The purpose of this study is to seek ways of utilizing TLBMC by understanding business model of social ventures that are accompanied by social and environmental as well as economic missions. In order to achieve this, business models from economic, environmental and social perspectives will be analyzed, and we seek to enhance sustainability of social venture entrepreneurs. As the analysis tool, TLBMC(Triple Layered Business Model Canvas) expands upon the business model canvas that is widely utilized and recognizes economical terms. The TLBMC is proposed by Joyce, A., & Paquin, R. L.(2016) to help achieve a holistic view with horizontal and vertical associations. The study tries to overcome limitations of previous studies and observe a variety of economic, environmental, and social perspectives that social ventures should have with the TLBMC. As a result, it has the following implications; Firstly, creating separate social, environmental and economic business model canvas helps a business to have a holistic approach. Secondly, it was found that social venture characteristics of environmental and social perspectives were applied in practice. Lastly, we have established experience data on social venture business model. This study focuses on the opinions, the meanings and the subjective views of the participants. As a result, conclusions are drawn by the researchers ' assertions and has limitations as a research on case studies. However, this study will help people who are preparing or studying social ventures to have economic, environmental, and social perspectives. Also, redefinition of the direction and value of entrepreneurs operating social ventures, such as vision and mission, will help clarify the roles and responsibility of organizations. As a fundamental step for future empirical studies, this study could be the base for social venture business model studies.

  • This paper aims at delivering significant implications to high-tech startups by visualizing the implementation process of leading KOSDAQ listed companies's business model. This paper founded two meaningful outcomes; first, hish-tech starts-up make a clear direction of implementing intangible business model in real business, second, targeting the role model of benchmarking business model among leading companies, by linking common feature between high-tech starts-up and leading KOSDAQ listed venutures sharing one of Key performance indexes falls on viable business model. The research results of visualizing the implementation of leading KOSDAQ listed ventures' business model shows three major implications. First, business model indicates not just simple logic of creating and delivering values, but more shows CEO leading management vehicle. Second, business model represents the multi-dimension process itself of integrating in and out company's core assets and competencies initiated by CEO. Third, financial outcomes of business model is automatic result of implementing on setting target customer, creating value, and delivering it rather than planned strategically. Fourth, the focal points of implementing business model falls on collecting real information from business sites.

  • Recently, there has been tremendous increase in human-computer/machine interaction system, where the goal is to provide with an appropriate service to the user at the right time with minimal human inputs for human augmented cognition system. To develop an efficient human augmented cognition system based on human computer/machine interaction, it is important to interpret the user's implicit intention, which is vague, in addition to the explicit intention. According to cognitive visual-motor theory, human eye movements and pupillary responses are rich sources of information about human intention and behavior. In this paper, we propose a novel approach for the identification of human implicit visual search intention based on eye movement pattern and pupillary analysis such as pupil size, gradient of pupil size variation, fixation length/count for the area of interest. The proposed model identifies the human's implicit intention into three types such as navigational intent generation, informational intent generation, and informational intent disappearance. Navigational intent refers to the search to find something interesting in an input scene with no specific instructions, while informational intent refers to the search to find a particular target object at a specific location in the input scene. In the present study, based on the human eye movement pattern and pupillary analysis, we used a hierarchical support vector machine which can detect the transitions between the different implicit intents - navigational intent generation to informational intent generation and informational intent disappearance.

  • This study aims to explore educational methods to help students and citizens, who are exposed to numerous manufactured risks, better understand the nature of science and technology. It also seeks to develop their ability to identify, analyze, and evaluate the risks associated with science and technology, ultimately enabling them to live safer lives in society. To achieve this, through an extensive literature review, we explored the definition of risk, the necessity of risk education, and the relationship between SSI (Socioscientific Issues) education and risk education. Based on the results, we proposed the SSI-CURE (Socioscientific Issues Centered on the Understanding of Risk and its Evaluation) model, which can systematically educate about risks in the context of SSI. The SSI-CURE model proceeds through the following four steps: 1) Confrontation of SSI, 2) Understanding the Nature of Science and Technology with SSI, 3) Risk Assessment in SSI, and 4) Enactment of Countermeasures for SSI. These steps represent the key elements for education on risks in the context of SSI: Conceptual understanding of risks (risk knowledge), competencies necessary for discussing or addressing risk situations (risk competency), scientific content knowledge needed to understand risks (knowledge in science), and knowledge required to understand the causes of risks and their impacts (knowledge about science). We expect that the SSI-CURE model can be used not only as a guide for instruction but also as a representative framework for developing programs to educate about risks in the SSI context.

  • With the increasing demand for office space, there have been questions on how office rent distribution produces a change in the urban spatial structure in Seoul. The purpose of this paper is to investigate a relative price gradient and to present a time-series model that can quantitatively explain the dynamic changes in the urban spatial structure. The analysis was dealt with office rent above 3,306 m2 for the past 10 years from 1Q 2010 to 4Q 2019 within Seoul. A modified repeat sales model was employed. The main findings are briefly summarized as follows. First, according to the estimates of the office price gradient in the three major urban centers of Seoul, the CBD remained at a certain level with little change, while those in the GBD and the YBD continued to increase. This result reveals that the urban form of Seoul has shifted from monocentric to polycentric. This shows that the spatial distribution of companies has gradually accelerated decentralized concentration implying that the business networks have become significant. Second, contrary to small and medium-sized office buildings that have undertaken no change in the gradient, large office buildings have seen an increase in the gradient. The relative price gradients in small and medium-sized buildings were inversely proportional among the CBD, the GBD, and the YBD, implying their heterogeneous submarkets by office rent movements. Presumably, those differences in the submarkets were attributed to investment attraction, industrial competition, and the credit and preference of tenants. The findings are consistent with the hierarchical system identified in the Seoul 2030 Plan as well as the literature about Seoul's urban form. This research claims that the proposed method, based on the modified repeat sales model, is useful in understanding temporal dynamic changes. Moreover, the findings can provide implications for urban growth strategies under rapidly changing market conditions.
