Recently, the Defense Advanced Research Projects Agency(DARPA) in the United States is studying a new concept of war called Mosaic Warfare, and MUM-T(Manned-Unmanned Teaming) through the division of missions between expensive manned and inexpensive unmanned aircraft is at the center. This study began with the aim of deriving the priority of autonomous functions according to the role of unmanned aerial vehicles in the present and present collaboration that is emerging along with the concept of mosaic warfare. The autonomous function of unmanned aerial vehicles between the presence and absence collaboration may vary in priority depending on the tactical operation of unmanned aerial vehicles, such as air-to-air, air-to-ground, and surveillance and reconnaissance. In this paper, ACE (Air Combat Evaluation), Skyborg, and Longshot, which are recently studied by DARPA, derive the priority of autonomous functions according to air-to-air collaboration, and use AHP analysis. The results of this study are meaningful in that it is possible to recognize the priorities of autonomous functions necessary for unmanned aircraft in order to develop unmanned aerial vehicles according to the priority of autonomous functions and to construct a roadmap for technology implementation. Furthermore, it is believed that the mass production and utilization of unmanned air vehicles will increase if one unmanned air vehicle platform with only essential functions necessary for air-to-air, air-to-air, and surveillance is developed and autonomous functions are expanded in the form of modules according to the tactical operation concept.

웹에서 이용할 수 있는 Annotation들은 개인 노트의 수단이며, 같은 일에 종사하는 동료들간의 커뮤니케이션과 협업할 수 있도록 도와준다. 이런 종이 책에서의 Annotation들을 웹에 적용함으로써 공유. 검색, 재편집 등의 장점을 얻을 수 있다. 웹 Annotation은 통신수단의 발달과 함께 증가한 인터넷 사용자들의 활발한 커뮤니케이션을 통해 빠르게 증가하고 있어 한 문서에 많은 Annotation이 생성된다. 현재, 웹 상의 Annotation에 관련된 연구들은 생성, 출력, 저장을 중심으로 연구되고 있으나 한 문서 또는 한 Anchor에 존재하는 많은 Annotation들을 효과적으로 제공하는 방법에 관한 연구는 미비한 실정이다. 기존 Annotation 시스템들의 대부분은 다수의 Annotation들을 관련성이나, 사용자 특성을 고려하지 않고, 입력된 순서로 Annotation을 제공한다. 때문에 Anchor의 이해시간을 가중시킨다. 또한, 생성된 모든 Annotation 제공으로 인해 문서에 너무 많은 Annotation들이 생성되어 문서의 레이아웃을 손상시킬 수 있어[1], 문서를 이해의 시간을 증가시킨다[2]. 따라서 본 논문에서는 웹 문서에 생성된 다수의 Anchor들과 Annotation들을 사용자에게 효율적으로 제공하기 위하여 사용자 관심사에 맞는 Anchor와 Annotation만을 제공하는 Annotation 필터링기법을 제안한다. 또한. 동일한 Anchor내에서 적절한 Annotation의 우선 접근을 위한 Annotation 순위 부여기법과 Annotation 필터링 결과에 따라 Anchor의 표현유무를 결정하는 Anchor 표현 기법을 제안한다.

In this study, we want to analyze the aspect that required in the classroom for the operation of NCS-based curriculum, the interest of specialized subject teachers on implementable teaching and learning methods. As a result, the overall interest in teaching-learning method of specialized subject teachers was similar to that of non-user patterns among four types of interest patterns. In other words, specialized subject teachers want to know more about teaching-learning method for applying NCS-based curriculum, but we are only aware of the general facts at present, and it seems that there is low interest in actual operation. In addition, there was no statistically significant difference in the degree of interest in the teaching-learning method according to general variables(gender, related training experience, career, and curriculum group) of the specialized subject teachers. The specialized subject teachers are not well aware of the influence of the teaching-learning method according to the introduction of NCS-based curriculum, and to that end, there was little interest in collaboration with colleagues.

Government funded research institutes (GFRIs) maintain a cooperative relationship with companies and stably provide their resources through the family company system. They are thereby implementing a demand-oriented support system that responds to the needs of the company. This study analyzed the changes in corporate financial performance depending on the participation in family company system and customized support. For this purpose, 2,229 companies registered with the KITECH during 2015-2017 composed the "Family company group", and 80 companies that participated in the customized support were selected as the "customized support group". The effect of participation on the corporate financial performance was analyzed using the PSM-DID model. The analysis verified that companies in a cooperative relationship with GFRIs had a higher sales growth rate than others. Furthermore, when these companies received additional customized support, their OI and ROE were significantly improved. The value of this study lies in that it quantitatively analyzed the cooperation performance of partner companies following a sustainable SME-GRI relationship. In addition, it provides insight into the strategic support system for SMEs by confirming the necessity of a customized support based on the relationship.

In the Hyper-connected society, each country set up its own policy and central government as well as provincial government makes a basic plan of developing IoT. Gyeonggi provincial government needs to cope actively with the changing international and national circumstances. The purpose of this paper is to frame policy as a provincial government with analysis IoT industry-academia-institute-governments ecosystem and in-depth interview. There are IoT related SMEs in Gyeonggi, especially manufacturing business and device fields. Universities are doing IoT researches by R&D funds from central as well as provincial governments. Central government-affiliated Institutions are researching. It is necessary for Gyeonggi provincial government to establish policy in order to actively operate IoT ecosystem while each innovation actors are cooperated in doing IoT; system/governce maintenance, environments and test-bed for the application.

The collective narratives on global crisis such as the displaced, uneven distribution of resources, invasion of human rights is more than a recurring theme or polemics in the fields of contemporary arts. In the latest projects from Olafur Eliasson, Rirkrit Tiravanija and Ai WeiWei, art works are presented as performative 'platforms' for tackling these undiscriminating reality of human conditions. Here, 'the users' as driving forces of possible change, are postulated as prospective actors/players who lead and collaborate to defy the status-quo. Crossing over the on/off lines, the everyday-activities of exchanging, sharing and networking are strategically deployed and its meaning reconfigured within the context of post/production discourse. This historical, yet unsettling juncture between art and life, dystopian reality and utopian idealism has its formal-conceptual links to Russian Constructivism, Brechtian Learning-Play and Joseph Beuys' Social Sculpture. Based on Nicolas Bourriaud's notion of Postproduction, this paper aims to provide a diachronic analysis on collaborative dispositions of participatory arts practices.

Enterprises as well as central and local governments have tried to apply ubiquitous technology to the actual life on the various types of business and projects. In this paper we develop strategic plan to provide public service on public areas based on needs analysis of public services as well as trend analysis of ubiquitous and web technology. Ubiquitous service model should be based on geospatial web which can incorporate participation and collaboration concepts, as the wire/wireless network system develop rapidly. To achieve this purpose, we suggest the following projects; 1), construction of internet map based on geospatial web technology, 2), development of web contents based on geospatial web, 3), installing ubiquitous equipment, and 4), upgrade Seoul Metropolitan Government's homepage and internet system which can incorporate web 2.0 concepts. Ubiquitous service model should be based on not only development of ubiquitous technology but also needs of consumer such as citizen, enterprises, and public sectors which have an interest in that place. Geospatial web will be the core of development of ubiquitous service models.

In smart work environment, a company provides employees a flexible work environment for tele-working using mobile phone or portable devices. On the other hand, such environment are exposed to the risks which the attacker can intrude into computer systems or leak personal information of smart-workers' and gain a company's sensitive information. To reduce these risks, the security administrator needs to analyze the usage patterns of employees and detect abnormal behaviors by monitoring VPN(Virtual Private Network) access log. This paper proposes a decision support system that can notify the status by using visualization and similarity measure through clustering analysis. On average, 88.7% of abnormal event can be detected by this proposed method. With this proposed system, the security administrator can detect abnormal behaviors of the employees and prevent account theft.

In this study, we propose the core factors and application of asymmetric virtual reality(VR) content in which head-mounted display(HMD) user and Non-HMD users can work together in a co-located space that can lead to various experiences and high presence. The core of the proposed asymmetric VR content is that all users are immersed in VR and participate in new experiences by reflecting widely a range of users' participation and environments, regardless of whether or not users wear the HMD. For this purpose, this study defines the role relationships between HMD user and Non-HMD users, the viewpoints provided to users, and the speech communication structure available among users. Based on this, we verified the core factors through the process of producing assistive asymmetric VR content and cooperative asymmetric VR content directly. Finally, we conducted a survey to examine the users' presence and their experience of the proposed asymmetric VR content and to analyze the application method. As a result, it was confirmed that if the purpose of asymmetric VR content and core factors between the two types of users are clearly distinguished and defined, the independent experience presented by the VR content together with perceived presence can provide a satisfactory experience to all users.

To transmit vital signal stream of mobile patients remotely, it requires mobility of patient and watcher, sensing function of patient's abnormal symptom and self-organizing service binding of related computing resources. In the existing relative researches, the vital signal stream is transmitted as a centralized approach which exposure the single point of failure itself and incur data traffic to central server although it is localized service. Self-organizing middleware platform based on heterogenous overlay network is a middleware platform which can transmit real-time data from sensor device(including vital signal measure devices) to Smartphone, TV, PC and external system through overlay network applied self-organizing mechanism. It can transmit and save vital signal stream from sensor device autonomically without arbitration of management server and several receiving devices can simultaneously receive and display through interaction of nodes in real-time.
