근래에 불가측성을 지닌 재난의 빈도가 증가함에 따라 우리는 각종 재난으로 인한 사회 불안 심리가 심화되는 추세이다. 이에 따라 사회 위기 현상으로 최근 우리 사회에 일어난 굵직한 재난에 대비하여 미래 사회의 안전한 대비책을 미리 마련하지 않으면 안 된다. 그러므로 우리는 사회 위기 관리 상황에 항상 대비하기 위해서 ICT 강국으로서 정부의 역할과 빅데이터 활용성 가치의 중요성을 인식하여야 한다. 이에 본 논문에서는 열거한 각종 재난 사례로 인간불안 심리를 분석하고, 이런 불안한 심리를 해소하는 방안으로의 사회 위기 관리 처방을 위해 우리 전자정부는 빅데이터를 공적으로 잘 활용할 수 있는 새로운 방안을 찾을 필요성을 가지고 사회 현안 측면의 빅데이터 주요 이슈 중요성과 시급성을 상대적 계열 분석으로 가시화 하였다. 또한 빅데이터 공공부문의 국내외 활용 동향과 함께 빅데이터 가치에 대한 새로운 실증적 접근 방향을 제시 하였다. 그리고 전자정부의 빅데이터 활용 방안으로 전자정부 역할의 중요성을 역설하고, 재난 대응의 사례 분석을 통해 불가측성을 지닌 여러 재난에 있어 사회 위기 관리를 위한 정부의 빅데이터 활용 방안으로서 함의를 지닌 정책을 제언 하였다.

Opened platform is called that anybody can be a producer and consumer in some platform. And many opened platforms are using in various area such as general goods, smart phone application and contents. In this paper, we will propose the opened platform system for the problems for evaluation the level of learners. Any user can register problems as public or private-type in this system and use them. So our proposed system has the advantage in selecting the high quality problems by continuous reviews about that even after they have been registered. Proposed system has three different modules such as submit, evaluate and produce problems modules. A user can submit various kind of problems in the submit module. The evaluation module is a module that allows the user who is not the problem registrant to evaluate the registered problem. The production module can use the registered problems for online and offline evaluation. 키워드 : 문제은행, 오픈 플랫폼, 문제 평가 Key word : problem bank, opened platform, problem evaluation Received 01 November 2016, Revised 03 November 2016, Accepted 14 November 2016 * Corresponding Author Yoo-hyun Park(E-mail:yhpark@deu.ac.kr, Tel:+82-51-890-1737 Department of Computer Software Engineering, Dongeui University, Pusan 47340, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.443 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Wireless Body Area Networks is an environment that provides an appropriate service remotely by collecting user’s biometric information. With the growing importance of sensor, WBAN also attracts extensive attention. Since WBAN is representatively used in the medical field, it can be directly related to the patient’s life. Hence security is very important in WBAN. Mutual authentication between the client and the application provider is essential. And efficiency is also important because a used device is limited to computation cost. In this reason, ID-based anonymous authentication scheme in WBAN has been intensively studied. We show that the recent research result of Wu et al. which is about the ID-based anonymous authentication scheme is vulnerable to impersonation attack. And we propose a new ID-based anonymous authentication scheme that is secure against the attacks discovered in the existing schemes. Compared to the existing schemes, the computation cost of our scheme is improved by 30.6% and 7.3%. 키워드 : 무선 신체 영역 네트워크, 익명성, 상호 인증, 위장 공격 Key word : Wireless Body Area Networks, Anonymity, Mutual Authentication, Impersonation Attack Received 10 November 2016, Revised 10 November 2016, Accepted 26 November 2016 * Corresponding Author Dong Hoon Lee(E-mail:donghlee@korea.ac.kr, Tel:+82-2-3290-4997) Graduate School of Information Security, Korea University, Seoul 02841, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.322 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

A test service for the weapon systems evaluation is one of the most important processes during the weapon systems acquisition or development life cycle. Before completion of weapon systems development, the appropriate evaluation test can reduce risk and expense which might be expected during weapon systems development procedure. In this paper, it is suggested that a probabilistic prediction method based on Monte Carlo simulation for how much the annual weapon systems evaluation test excution ratio can be reached compared to the yearly initial planned test quantity. And then a weapon systems evaluation test quantitative management scheme is suggested to assist decision making for the test schedule manager who can arrange monthly test schedule based on the prediction result of annual test excution ratio. And the proposed method is applied for the weapon systems evaluation firing test data of the 8th directorate, Agency for Defense Development(ADD). And also the application result is examined.

In general, distribution board, panel board and motor control center can be installed over a wide area such as residence of group, building, schools, factories, ports, airports, water service and sewerage, substation and heavy industries that are used to supply converts the voltages extra high voltage into optimal voltage. There are electrical accidents due to rise of contact temperature, loose contact between busbar, deterioration of the contact resistance, over temperature of the busbars. In this paper, we designed and implemented the busbar joint and temperature measurement system, which can measure the joint resistance of busbar and loose connection between busbar using potentiometer and non-contact infrared sensor. The experimental results show that tightening the bolt and nut is fully engaged, resistance was decreased and maximum error range was 0.1mm. Also, the experimental result showed that the temperature at the contact area is increased from 27.3°C to 69.3°Cby the contact resistance. 키워드 : 부스바, 배전반, 분전반, 전동기제어반, 체결상태 모니터링 Key word : Busbar, distribution board, panel board, motor control center, busbar joint monitoring Received 08 November 2016, Revised 11 November 2016, Accepted 23 December 2016 * Corresponding Author Young-Dong Lee(E-mail:ydlee@cs.ac.kr, Tel:+82-55-250-1312) Department of Computer Software Engineering, Changshin University, Changwon 51352, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.379 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

FANET is an ad hoc network formed among the unmanned aircraft in the three-dimensional space for data transfer. Most of the research on FANET application has focused on the use of the camera sensor mounted on the unmanned aircraft to collect data from the ground, and process and delivery of the data for a specific purpose. However, the research on the fusion of WBAN and FANET that collects the data of the human body and passes through the FANET has not been studied much until now. Therefore, in this study, we study the data transmission system that collects the human body data of people working in the areas that are vulnerable to communication difficulties and passes the collected data through the FANET. In particular we analyze the possible methods to transfer the emergency data of the body in the fusion network of WBAN and FANET and provide a data transfer model that can be transmitted most efficiently.

In particular we analyze the possible methods to transfer the emergency data of the body in the fusion network of WBAN and FANET and provide a data transfer model that can be transmitted most efficiently.","PeriodicalId":136663,"journal":{"name":"The Journal of the Korean Institute of Information and Communication Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116243728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The robot control with safety consideration is required since robots and human work together in the same space more frequently in these days. For safety, robots must have compliance to human force and robust tracking performance with high impednace for the nonhuman disturbances. The novel idea is proposed to achieve the compliance and high impedance with one controller structure. For the compliance, the ISMC(Integral Sliding Mode Control) and HDOB(Human Disturbance Observer) The human force is identified by using the human band pass filter and its output is sent to the sliding surface. The sliding mode dynamic is affected by human disturbance and the compliance for human is achieved. The disturbances besides human frequencies are decoupled by the ISMC and the robust tracking is achieved. The additional LDOB(Low Frequency Disturbance Observer) decreases the maxim nonlinear gain and leads low chattering. The introduction of human disturbance into the sliding mode dynamic is the main novel idea of this paper. 키워드 : 적분슬라이딩모드, 외란관측기, 컴플라이언스, 강인로봇제어, 인간순응제어 Key word : Integral Sliding Mode, Disturbance Observer, Compliance, Robust Robot Control, Human-Compliance Control Received 29 November 2016, Revised 01 December 2016, Accepted 19 December 2016 * Corresponding Author Gun-Pyong Kwak(E-mail:kwak@changwon.ac.kr, Tel:+82-55-213-3637) Department of Electrical Engineering, Changwon National University, Changwon 51140, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.416 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

This paper proposes a road segmentation algorithm using a watershed. The proposed algorithm is a segmentation algorithm using an automatic marked watershed that automatically creates a road marker and a background marker using information about vehicles and lanes on road and it can solve problems of a watershed-based segmentation such as overmany regions or handworks for markers. The road marker has property for pure road areas in which lanes are included but vehicles are excluded and the background marker has property for the areas left in which vehicles and background are included. Results of segmentation applied to real road images show that the proposed algorithm can automatically creates appropriate markers and it can properly segments the required road area that include the lane with a vehicle and its both side lanes in various environments, and it is equal to the conventional algorithm using markers created by handwork in performance. 키워드 : 차도, 영역 분할, 자동, 마커, watershed Key word : road, segmentation, automatic, marker, watershed Received 22 September 2016, Revised 27 September 2016, Accepted 01 October 2016 * Corresponding Author Jeong-su Oh(E-mail:ojs@pknu.ac.kr, Tel:+82-51-629-6414) Department of Display Engineering, Pukoyng National University, Pusan 48508, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.409 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
