본 연구는 뉴스 빅데이터에 나타난 메타버스 관련 이슈들을 교육관점에서 분석하여 그 특징을 탐색하고, 메타버스의 교육적 활용가능성 및 미래교육에 대한 시사점을 제공하는데 목적이 있다. 이를 위해 포털사이트에서 검색되는 메타버스 관련 뉴스 데이터를 41,366건 수집하였고, 대표적인 용어 가중치 모델인 TF-IDF를 이용하여 추출된 모든 키워드의 가중치 값을 계산하여 순위화한 후, 워드클라우드로 시각화 분석을 수행하였다. 또한 정교한 확률기반 텍스트마이닝 기법인 토픽모델링(LDA)을 활용하여 주요 토픽들을 분석하였다. 연구결과 교육관점에서 메타버스의 핵심 이슈로는 플랫폼 산업, 미래인재, 기술의 확산 등과 같은 주제가 도출되었다. 또한, 기술, 직업, 교육이라는 세 개의 핵심 주제로 2차 데이터 분석을 실시한 결과 미래교육에서 메타버스는 교육플랫폼의 혁신, 미래 직업의 혁신, 미래 역량의 혁신과 관련한 이슈를 갖는 것으로 나타났다. 본 연구는 방대한 양의 뉴스 빅데이터를 단계적으로 분석하여 교육관점에서 이슈를 도출하고 미래교육에 대한 시사점을 제공하였다는 데 의의가 있다.

Sensitive issues are both common and problematic for health care providers because sensitive issues may interfere with the future provider-client relationship and effective care. Most current training for providers focuses on a particular issue, but this is inadequate because many issues may be sensitive, and which issues will be sensitive is unpredictable. We argue that issues become sensitive when they activate one or more of three common triggers, fear, stigma, and taboo. A cycle of negative internal and interpersonal responses to the sensitive issue often leads to unresolved health issues for clients and stress and feelings of inadequacy for providers. We recommend integrated pre-service and in-service skill building to help individual health care providers respond appropriately to a wide variety of sensitive issues. We also identify specific policies and procedures to strengthen organizational support for caregivers so that providers can address these sensitive issues effectively with their clients.

The purpose of this study is to discuss the issues and problems of interior design education in Korea and to further present guidelines for curriculum development and research on interior design education in Korea for the 21st Century. Content analysis and scholastic inquiry from various sources were used to examine the issues concerning 1) professional identity, 2) curriculum structure, and 3) creative scholarship including interdisciplinary approach. Identification of these issues presented in this study will allow interior design educators to help prepare interior design students who are qualified to lead the profession in the future.

The Fukushima Dai-Ichi accident in 2011 has affected various aspects of the nuclear society worldwide. The accident revealed some problems in the conventional approaches used to ensure the safety of nuclear installations. To prevent such disastrous accidents in the future, we have to learn from them and improve the conventional approaches in a more systematic manner. In this paper, we will cover three issues. The first is to identify the key issues that affected the progress of the Fukushima Dai-Ichi accident greatly. We examine the accident from a defense-in-depth point of view to identify such issues. The second is to develop a more systematic approach to enhance the safety of nuclear installations. We reexamine nuclear safety from a risk point of view. We use the concepts of residual and unknown risks in classifying the risk space. All possible accident scenarios types are reviewed to clarify the characteristics of the identified issues. An approach is proposed to improve our conventional approaches used to ensure nuclear safety including the design of safety features and the safety assessments from a risk point of view. Finally, we address some issues to be improved in the conventional risk assessment and management framework and/or practices to enhance nuclear safety.

Purpose - One of the biggest problems in the e-learning distribution process is the lack of quality content and learners' discredit in e-learning content. In order to respond to the various demands of the corporate education field appropriately, it is necessary to search for directions of new e-learning models that are out of traditional e-learning contents. The purpose of this study is to identify recent trend issues related to corporate e-learning and to suggest directions for development. Research design, data, and methodology - Based on the literature review, trend issues that should be considered important in corporate e-learning were derived. Online survey was conducted to evaluate the importance-feasibility of each issue to 13 experts on e-learning and corporate education. The contents of the questionnaire are as follows: 1) recognition of importance and feasibility of trend issues to be considered important in the future corporate education field; 2) factors to be considered in developing future e-learning contents. Results - Six trends derived from a comprehensive literature review. The most important e-learning trends for corporate education field were 'mobile learning', 'micro learning', 'blended learning', 'social learning', 'adaptive learning', 'engaged learning'. As a result of evaluating the importance and feasibility of each issue, experts point out that 'mobile learning' and 'micro learning' should be actively considered for introduction and utilization at present. In addition, 'social learning' and 'blended learning' need to be actively considered in the near future. On the other hand, experts recognized that 'adaptive learning' and 'engaged learning' need to be prepared from a long-term perspective. Conclusions - There are two main reasons for this result. First, in corporate e-learning, it is important to 1) be able to update on time, 2) the connection with the workplace is important. Second, it requires realistic verification of the expected performance of the learning model. To be considered part of the future are as follows: First, the value and effectiveness of the new e-learning type should be studied. Seconds, e-learning contents should be developed through adopting SAM or Agile methodology. Through this process, we would be able to enhance the quality in e-learning content.

그 동안 사이버 테러와 관련하여 우리나라에서 많은 양질의 지식이 축적되어 왔음에도 불구하고 몇 가지 매우 중요한 취약점이 지적될 수 있다. 그리고 이러한 취약점을 극복해 보려는 시도가 이 논문의 주요 논제이다. 기존 사이버 테러관련 논의나 연구를 살펴볼 때 아쉬운 점으로 파악되었던 사항은 사이버 테러와 관련된 여러 현상들이 빚어내는 미래의 안보환경에서 국가안보전략 개발이라는 거시적 프레임에서 사이버 테러문제를 접근하는 논의가 없었다는 점이다. 이 논문은 이러한 사항에 중점을 두고 사이버 테러에 대한 논의를 전개할 것이다. 바꾸어 말하면 이 논문의 목적은 안보위협의 한 양식으로서 사이버 테러가 던지는 국가안보위협의 의미를 재평가하고 미래안보환경에서 국가안보전략 개발이라는 틀 속에서 사이버 테러의 문제를 재조명 한다. 이 논의에서 다루는 사이버 테러에 관련된 몇 가지 쟁점들은 사이버 공간이 추가된 미래안보환경에서 국가안보의 전략적 접근 틀의 구성에 중요한 메시지를 전달한다. 미래 환경에서 사이버라는 새로운 특성을 가진 공간 환경이 국가안보와 사회 및 개인안전에 중요한 외부조건의 하나로 추가되었다는 사실을 직시하고 기존의 4차원에 사이버가 추가된 5차원 공간환경에서 어떻게 새로운 국가안보전략이 마련되어야 하는지에 대한 기본 전략 틀이 마련되어야 한다. 이러한 전제위에 미래의 기술진보의 양상과 방향이 파악되어야 하고, 위협의 주체와 성격과 유형이 분석되어야 한다. 사이버 테러의 위협과 성격은 이런 맥락에서 다루어져야한다. 한편 이러한 기반위에 다시 사이버 테러를 포함한 여러 미래사회에 예상되는 위협들과 위협 주체들에 대응하기 위한 방안들이 기능과 시스템 면에서 동시에 수립되어야 한다.

The rapid growth of smart devices demands an enhanced throughput for network connection sustainability during mobility. However, traditional wireless network architecture suffers from mobility management issues. In order to resolve the traditional mobility management issues, we propose a novel architecture for future wireless access network based on software-defined network (SDN) by using the advantage of network function virtualization (NFV). In this paper, network selection approach (NSA) has been introduced for mobility management that comprises of acquiring the information of the underlying networking devices through the OpenFlow controller, percepts the current network behavior and later the selection of an appropriate action or network. Furthermore, mobility-related scenarios and use cases to analyze the implementation aspects of the proposed architecture are provided. The simulation results confirm that the proposed scenarios have obtained a seamless mobility with enhanced throughput at minimum packet loss as compared to the existing IEEE 802.11 wireless network.
