사물인터넷 기술은 기본적으로 다양한 대규모의 IoT 디바이스가 인터넷에 연결되어 디바이스로부터 수집되는 데이터을 통해 스마트한 서비슬 제공하는 기술이다. 그러나, 이런한 환경은 역으로 다양한 사양의 다비이스가 네트워크에 연결되기 때문에 가장 취약한 지점으로 통해 IoT 네트워크를 공격할 수 있게 된다. 따라서, 저사양 IoT 디바이스일지라도 전제 연결 네트워크의 보안 수준에 걸맞는 보안강도를 보장해야 하는 다소 역설적인 상황에 봉착하게 된다. 이러한 상황을 해결하기 위해 저사양 IoT 디바이스의 보안을 강화할 수 있는 기술이 시급하다고 할 수 있다. 본 논문에서는 이를 위해 PUF 개념을 일반화하여 디바이스 DNA라는 새로운 개념을 정의하고 기본적인 디바이스 DNA의 성질을 바이오인식 기술에서 차용하여 설명하고자 한다.

Necessity of smart work that can change environment of working in organizations has been emphasized. Lots of organizations, however, wish to do work with smartness through adoption of smart work technologies, those are not sure whether smart work will be successful or not till now. Especially, viewpoints of leaders concerning efficiency and effectiveness of smart work who operate the organizations may be different in many circumstances such as industries, characteristics of work, etc. Therefore, hopefully, this research want to investigate whether differences among leader and non-leader group, tendencies of personal leadership styles in work exit or not by empirical and exploratory approach. Totally, 118 questionnaires had been collected and performed test of mean difference between groups. As a result, some items such as working place, working methods, flexible time and tension of smartwork showed significant differences between level of leadership styles and non-leader and leader groups. And, futhermore, from this research I believe that we can have a few insights for successful smart working environment in organizations.

Smart-Learning has been increasing with the growth of smartphone usage. Looking at previous research, this study established the concept of smart learning, current understanding of smart learning and the requirements for smart learning. Subsequently, It was established a concept of SNS, reviewing future education, self-directed learning by using social network, and suggests policies of vitalizing smart-learning by using SNS. In order to use SNS in smart learning, first it is proposed the need for smart learning laws and institutions, particularly with young people considering their emotions in order to expand what is proposed. secondly, the need for SNS usage to be socially and culturally relevant. third and finally, the need for strengthening information security with co-operation from the government.

현재의 스마트폰 기반의 모바일 애플리케이션은 기본적인 전화, 문자와 같은 기능들 외 네비게이션과 같은 유용하고 편리한 기능들이 사용되고 있다. 이러한 애플리케이션에는 사용자와 관련된 많은 개인 정보들이 포함되어있고, 저장된 개인 정보는 사건 발생 시 사건의 직접적인 증거 혹은 간접적은 증거로 활용될 수 있다. 스마트폰에 저장된 증거를 수집하고 분석할 때 조사관들이 사용할 수 있는 기존의 도구는 복잡한 사용방법을 숙지해야 하고, 인증된 소프트웨어가 설치되어 있는 컴퓨터에서 국한되어 분석이 가능했다. 본 논문에서는 이와 같은 문제를 해결하기 위한 웹 서비스 개념의 스마트폰 포렌식 프레임워크를 제시한다.

정보통신기술의 발달은 개인용 컴퓨터나 노트북 컴퓨터와 같은 컴퓨터를 중심으로 이루어진 네트워킹 및 인터넷 환경을 컴퓨터를 포함한 스마트폰, PDA, 휴대용 멀티미디어 기기와 같이 이동이 가능한 소형의 기기를 중심으로 변화시키고 있다. 그러나, 연산, 통신 및 네트워킹 기능이 가능한 소형 장치들은 정보화 기기뿐만 아니라 계량기, 온도계와 같은 일반적인 사물에도 부착될 수가 있다. 사물에 부착된 이러한 소형 장치들은 사물의 정보를 자동으로 획득하게 해주거나 사물간의 통신 네트워크를 통해 정보의 상호 공유가 가능해진다. 이와 같이 사물에 부착된 통신 장치를 이용하여 사물이 네트워크에 연결되거나 사물간에 통신 네트워크를 구성하여 정보를 공유하는 개념 및 기술을 지칭하는 용어로 IoT, M2M 및 사물지능통신 등이 있다. 이러한 네트워크 환경에서는 사람 대 사람, 사람 대 사물뿐만 아니라 사물 대 사물간의 통신 네트워크가 가능해져 모든 객체간의 정보 공유가 가능해지며 이는 미래 유비쿼터스 정보 서비스 사회로 진화하기 위한 필수적인 기술 요소라 할 수 있을 것이다.

With many types of data generated in the shift of business environment as a result of growth of an organization or enterprise, there is a need to improve the data-processing efficiency in smarter means with a single domain model such as Data Lake. In particular, creating a logical single domain model from physical partitioned multi-site data by the finite resources of nature and shared economy is very important in terms of efficient operation of computing resources. Based on the advantages of the existing Data Lake framework, we define the CDA-Concept (connected data architecture concept) and functions of Data Lake Framework over Abyss Storage for integrating multiple sites in various application domains and managing the data lifecycle. Also, it performs the interface design and validation verification for Interface #2 & #3 of the connected data architecture-concept.

Due to the recent transition to a non-face-to-face society, many organizations are quickly adapting to foster a smart work environment. The introduction of smart work does not simply end with incorporating ICT systems or solutions into business models since fundamental factors such as forms of employment and work styles need to be in line with the progression of technological advances. However, previous studies regarding smart work focus on improvements in productivity and efficiency from a technology acceptance perspective. Therefore, there is a lack of discussion on innovation resistance from employees and management control when ICT systems are introduced into the workplace. This study empirically analyzes the moderating effects of the organizational control method for employees and innovation resistance within a smart work environment. Additionally, this study aims to identify the structural characteristics that employees resist from an innovation resistance perspective when organizational innovation occurs. The empirical analysis of this study suggests that when smart work such as ICT technology is introduced into the workplace the level of innovation resistance decreases when there is a high level of relative advantage and self-efficacy, whereas the level of innovation resistance increases when there is a high level of use complexity. Moreover, this study revealed that the level of innovation resistance increases when the employees' behaviors were controlled. The results of this study intend to contribute to improving business management by suggesting factors worth considering when incorporating smart work into work places through a thorough case analysis.

The ICC is amending international trade rules such as Incoterms to respond to periodically changing international trade environments. Moreover, a drafting group has been formed for developing the eighth amendment and the Incoterms. Due to the recent development of information and communication technology, interest in smart work is increasing globally. Smart work is a concept that enables works to be performed without time and space constraints, and the mobile office is a typical form of smart work. Smart work has brought significant changes to the way that workers perform their jobs, and it has considerable impacts on international trade transactions. This study examines the impact of the development of information and communication technology on electronic trade customs and analyzes the revision process of Incoterms for electronic document informatization. Also, we provide implications for the 8th amendment of Incoterms.
