    Implementation of Vertigo Warning function for FA-50 aircraft

    Eun-Kyung You , Kim, Hyeock-Jin | 2019, 24(10) | pp.1~9 | number of Cited : 1
    Abstract PDF
    Fighter pilots are taking ‘Advanced Pilot Training’ courses to perform their missions perfectly even under adverse conditions. However, there are accidents that fall due to problems with the human body’s equilibrium in the acceleration of flight, falling into the ‘Vertigo, Spatial disorientation’ phenomenon. As such, accidents that fighters fall due to spatial disorientation frequently occur not only in Korea but also abroad. In this study, we implemented the ‘Vertigo’ warning function in the fighter. First, we analyzed the aircraft’s mission computer and the currently implemented warning functions. And we studied the coordinate system to utilize the aircraft attitude information. Based on this, we wanted to provide a visual warning to the HUD when the fighter flies over a certain time in the inverted flight position. Implementing this feature is expected to improve pilot flight safety. In addition, based on the results of this study, we propose a method to implement warning functions through linkage with other subsystems.

    Attack Surface Expansion through Decoy Trap for Protected Servers in Moving Target Defense

    Tae-Keun Park , Kyungmin Park , Daesung Moon | 2019, 24(10) | pp.25~32 | number of Cited : 1
    Abstract PDF
    In this paper, we propose a method to apply the attack surface expansion through decoy traps to a protected server network. The network consists of a large number of decoys and protected servers. In the network, each protected server dynamically mutates its IP address and port numbers based on Hidden Tunnel Networking that is a network-based moving target defense scheme. The moving target defense is a new approach to cyber security and continuously changes system’s attack surface to prevent attacks. And, the attack surface expansion is an approach that uses decoys and decoy groups to protect attacks. The proposed method modifies the NAT table of the protected server with a custom chain and a RETURN target in order to make attackers waste all their time and effort in the decoy traps. We theoretically analyze the attacker success rate for the protected server network before and after applying the proposed method. The proposed method is expected to significantly reduce the probability that a protected server will be identified and compromised by attackers.

    Extraction of Motion Parameters using Acceleration Sensors

    Yonghee Lee , Kang-Woo Lee | 2019, 24(10) | pp.33~39 | number of Cited : 0
    Abstract PDF
    In this paper, we propose a parametric model for analyzing the motion information obtained from the acceleration sensors to measure the activity of the human body. The motion of the upper body and the lower body does not occur at the same time, and the motion analysis method using a single motion sensor involves a lot of errors. In this study, the 3-axis accelerometer is attached to the arms and legs, the body's activity data are measured, the momentum of the arms and legs are calculated for each channel, and the linear predictive coefficient is obtained for each channel. The periodicity of the upper body and the lower body is determined by analyzing the correlation between the channels. The linear predictive coefficient and the periodic value are used as data to measure the type of exercise and the amount of exercise. In the proposed method, we measured four types of movements such as walking, stair climbing, slow hill climbing, and fast hill descending. In order to verify the usefulness of the parameters, the recognition results are presented using the linear predictive coefficient and the periodic value for each motion as the neural network input.

    Design Flaws and Cryptanalysis of Cui et al’s User Authentication Scheme

    Mi Og Park | 2019, 24(10) | pp.41~48 | number of Cited : 1
    Abstract PDF
    In 2018, Cui et al proposed a three-factor remote user authentication scheme using biometrics. Cui et al claimed that their authentication scheme is vulnerable to eavesdropping attack, stolen smart card attack, and especially Dos(denial-of-service) attack. Also they claimed that it is safe to password guessing attack, impersonation attack, and anonymity attack. In this paper, however, we analyze Cui et al’s authentication scheme and show that it is vulnerable to replay attack, insider attack, stolen smart card attack, and user impersonation attack, etc. In addition, we present the design flaws in Cui et al’s authentication scheme as well.

    Notes On Inverse Interval Graph Coloring Problems

    Chung Yerim , Hak Jin Kim | 2019, 24(10) | pp.57~64 | number of Cited : 0
    Abstract PDF
    In this paper, we study a polynomially solvable case of the inverse interval graph coloring problem. Given an interval graph associated with a specific interval system, the inverse interval graph coloring problem is defined with the assumption that there is no proper K-coloring for the given interval graph, where K is a fixed integer. The problem is to modify the system of intervals associated with the given interval graph by shifting some of the intervals in such a way that the resulting interval graph becomes K-colorable and the total modification is minimum with respect to a certain norm. In this paper, we focus on the case K=1 where all intervals associated with the interval graph have length 1 or 2, and interval displacement is only allowed to the righthand side with respect to its original position. To solve this problem in polynomial time, we propose a two-phase algorithm which consists of the sorting and First Fit procedure.

    Big Data Processing and Performance Improvement for Ship Trajectory using MapReduce Technique

    Kim Kwang-il , Joo-sung, Kim | 2019, 24(10) | pp.65~70 | number of Cited : 2
    Abstract PDF
    In recently, ship trajectory data consisting of ship position, speed, course, and so on can be obtained from the Automatic Identification System device with which all ships should be equipped. These data are gathered more than 2GB every day at a crowed sea port and used for analysis of ship traffic statistic and patterns. In this study, we propose a method to process ship trajectory data efficiently with distributed computing resources using MapReduce algorithm. In data preprocessing phase, ship dynamic and static data are integrated into target dataset and filtered out ship trajectory that is not of interest. In mapping phase, we convert ship's position to Geohash code, and assign Geohash and ship MMSI to key and value. In reducing phase, key-value pairs are sorted according to the same key value and counted the ship traffic number in a grid cell. To evaluate the proposed method, we implemented it and compared it with IALA waterway risk assessment program(IWRAP) in their performance. The data processing performance improve 1 to 4 times that of the existing ship trajectory analysis program.

    Analysis and Suggestions of Digital Heritage Policy

    LEE JONGWOOK | 2019, 24(10) | pp.71~78 | number of Cited : 0
    Abstract PDF
    In this paper, we divided domestic and foreign digital cultural activation policies into four types. We also described projects of each policy and analyzed the limitations of the policy. Finally, we suggested solutions to overcome these limitations. Changes in daily life caused by the recent development of 5G network technology, augmented reality, and virtual reality technology have brought many changes in the way of preservation and utilization of cultural heritage. In particular, digital technology is used for digitization of cultural heritage, storing, and managing digital data, digitally restoring cultural heritage, and enabling time, space, multi-sensory experiences. For this purpose, new policies was required to utilize this. This study divides domestic and international digital heritage policies into digital infrastructure construction, sharing and communication platform construction, public relations, and demonstration contents production support policies. This study is meaningful in classifying the fields of digital heritage policy and introducing digital heritage policy trends. It is also meaningful to suggest ways to improve digital heritage policies through analysis of domestic and foreign cases.

    Efficient Processing of k-Farthest Neighbor Queries for Road Networks

    Taelee, Kim , Hyung-Ju Cho , Hee Ju Hong and 4 other persons | 2019, 24(10) | pp.79~89 | number of Cited : 1
    Abstract PDF
    While most research focuses on the k-nearest neighbors (kNN) queries in the database community, an important type of proximity queries called k-farthest neighbors (kFN) queries has not received much attention. This paper addresses the problem of finding the k-farthest neighbors in road networks. Given a positive integer k, a query object q, and a set of data points P, a kFN query returns k data objects farthest from the query object q. Little attention has been paid to processing kFN queries in road networks. The challenge of processing kFN queries in road networks is reducing the number of network distance computations, which is the most prominent difference between a road network and a Euclidean space. In this study, we propose an efficient algorithm called FANS for k-FArthest Neighbor Search in road networks. We present a shared computation strategy to avoid redundant computation of the distances between a query object and data objects. We also present effective pruning techniques based on the maximum distance from a query object to data segments. Finally, we demonstrate the efficiency and scalability of our proposed solution with extensive experiments using real-world roadmaps.

    Index-based Boundary Matching Supporting Partial Denoising for Large Image Databases

    Bum-Soo Kim | 2019, 24(10) | pp.91~99 | number of Cited : 0
    Abstract PDF
    In this paper, we propose partial denoising boundary matching based on an index for faster matching in very large image databases. Attempts have recently been made to convert boundary images to time-series with the objective of solving the partial denoising problem in boundary matching. In this paper, we deal with the disk I/O overhead problem of boundary matching to support partial denoising in a large image database. Although the solution to the problem superficially appears trivial as it only applies indexing techniques to boundary matching, it is not trivial since multiple indexes are required for every possible denoising parameters. Our solution is an efficient index-based approach to partial denoising using R*-tree in boundary matching. The results of experiments conducted show that our index-based matching methods improve search performance by orders of magnitude.

    A Study on the Factors Affecting the Use of the Military Battlefield Management System in the Non-voluntary Use Environment

    Jungik Cho , Ahn, Hyunchul | 2019, 24(10) | pp.101~116 | number of Cited : 3
    Abstract PDF
    In this paper, we propose a novel behavioral model that explains the use of the military battlefield management system more effectively in the non-voluntary use environment. This study intends to suggest a model based on the Unified Theory of Acceptance and Use of Technology(UTAUT), an extended TAM. Also, it introduces the concept of 'Conative IS use' as a dependent variable that can explain user's behavior more effectively in non-voluntary technology acceptance environment. In addition, we propose the major factors affecting the UTAUT components from the TOE(Technology-Organization- Environment) perspectives, and analyze their effects. In order to validate the proposed model, this study applies PLS(Partial Least Squares) to the survey collected from military personnel. The findings of our study may shed a light on improving the effectiveness of battlefield management information system.

    Location Trigger System for the Application of Context-Awareness based Location services

    Yonsik Lee , Jang Minseok | 2019, 24(10) | pp.149~157 | number of Cited : 2
    Abstract PDF
    Recent research has been actively carried out on systems that want to optimize resource utilization by analyzing the intended behavior and pattern of behavior of objects (users, consumers). A service system that applies information about an object's location or behavior must include a location trigger processing system for tracking an object's real-time location. In this paper, we analyze design problems for the implementation of a context-awareness based location trigger system, and present system models based on analysis details. For this purpose, this paper introduces the concept of location trigger for intelligent location tracking techniques about moving situations of objects, and suggests a mobile agent system with active rules that can perform monitoring and appropriate actions based on sensing information and location context information, and uses them to design and implement the location trigger system for context-awareness based location services. The proposed system is verified by implementing location trigger processing scenarios and trigger service and action service protocols. In addition, through experiments on mobile agents with active rules, it is suggested that the proposed system can optimize the role and function of the application system by using rules appropriate to the service characteristics and that it is scalable and effective for location-based service systems. This paper is a preliminary study for the establishment of an optimization system for utilizing resources (equipment, power, manpower, etc.) through the active characteristics of systems such as real-time remote autonomous control and exception handling over consumption patterns and behavior changes of power users. The proposed system can be used in system configurations that induce optimization of resource utilization through intelligent warning and action based on location of objects, and can be effectively applied to the development of various location service systems.

    Integrated Safety System based on IoT

    shin jin seob | 2019, 24(10) | pp.159~165 | number of Cited : 1
    Abstract PDF
    About 58% of fires are electric fires. In this study, we analyzed the factors of fire caused by electricity and studied the system that can prevent fire in advance. In order to prevent disasters, basically, various electrical IoT sensors are needed to detect fire signs. Each of these sensors continuously receives a lot of situation information and sends it to the main system. The collected big data continuously checks whether the disaster is over the threshold that can cause disaster through pattern analysis, and can check whether there is any problem by comparing the data. In the event of a threshold, alarms are signaled and problems are reported. This prevents fire by preventing electrical problems such as overcurrent and leakage current.

    Hyun-Chang Lee , Seong-Yoon Shin , Kihong Park | 2019, 24(10) | pp.189~194 | number of Cited : 0
    Abstract PDF
    In the healthcare system, the human neck(cervical spine) is one of the most important organs. The area that supports the human head is the cervical spine. Nowadays, we are often overworked our neck to calls with the smart phone or see the monitors. In this paper, we investigate the abnormalities of lateral flexion and rotation of the cervical spine. The normal angle of lateral flexion is 20 ° to 45 ° and the normal angle of rotation is 50 ° to 90 °. If this angle is below normal and we feel pain, there is something wrong with the cervical spine. In addition, learn how to measure the lateral flexion and rotation of the neck or cervical spine, and also to find out how to treat an abnormality. We also look at how to prevent more than lateral flexion and rotation of the cervical spine. The experiment was carried out with 100 people in their 50s, men and women, to find out whether the neck is abnormal.

    Jihee Nam , Dongsu Kang | 2019, 24(10) | pp.195~203 | number of Cited : 0
    Abstract PDF
    Inadequate military soldiers cause military fatigue and rejection such as reduced confidence in the military and combat power. The military developed and applied a self-adopting test as a psychological test system to identify soldiers who are not fit to serve in the military in advance and prevent accidents. In this paper, we propose the ontology design process to be used for identifying accident concerns and implement the behavioral patterns and symptoms of maladjustment soldiers as ontology. The ontology design process is validated consistency and suitability as a result of the performance evaluation of ontology implemented. Through ontology design for identifying maladjustment soldiers, it is expected to play an effective role in preventing accidents by providing objective criteria and sharing of information on accident concerns.

    Ji-Hye Park , SoungWoong Yoon , Lee Sang Hoon | 2019, 24(10) | pp.205~213 | number of Cited : 0
    Abstract PDF
    Network robustness is one of the most important characteristics needed as the network. Over the military tactical communication network, robustness is a key function for maintaining attack phase constantly. Tactical Information Communication Network, called TICN, has mixed characteristics of lattice- and tree-type network topology, which looks somewhat weak in the viewpoint of network robustness. In this paper, we search articulation points and bridges in a current Tactical Information Communication Network using graph theory. To improve the weak points empirically searched, we try to add links to create the concrete network and then observe the change of network-based verification values through diminishing nodes. With these themes, we evaluate the generated networks through SNA techniques. Experimental results show that the generated networks' robustness is improved compared with current network structure.

    Hyun-Sun Park , Hyun-Joo Kim , Chang-Suek Choi | 2019, 24(10) | pp.215~223 | number of Cited : 1
    Abstract PDF
    Driving after drinking is highly likely to cause accidents due to lack of responsibility and poor judgment. South Korea is seeking a sentence for accidental drinking accidents. The suspended jail term for drunk drivers accounts for more than 70 percent of the total. However, those who come to the probation office during the probation period are involuntary, subject to little motivation for change, and the large-scale, collective, and short-term education offered to them is limited in preventing re-off. In addition to small group and long-term education, we conducted intensive short-term interventions to see changes in drinking habits in three months. In the long run, the effectiveness of drinking control will be demonsstrated, making a difference in improving the programs offered to drunk drivers in the future. Drunk driving accouts for a very high percentage of the causes of traffic accidents, which, like many countries around the world, should make efforts to prevent and punish drunk driving.

    A Study on the Judgment Criteria for the Trademark Dilution of Famous Marks

    park , Sang-Ouk Noe | 2019, 24(10) | pp.225~232 | number of Cited : 0
    Abstract PDF
    The trademark dilution of famous marks as a kind of unfair competition practice is defined and regulated in Article 2 (1) (c) of the Unfair Competition Prevention and Trade Secret Protection Act (hereinafter referred to as the Unfair Competition Prevention Act), which was newly established according to the amendment of the Act on February 3, 2001. Famous trademarks are universally protected in all around the world, which are likewise protected in the Republic of Korea by the Unfair Competition Prevention Actin line with such international trends. In order to establish the trademark dilution of famous marks, it is necessary to have the following characteristics: (1) high reputation of the original mark, (2) use of identical or similar markscompared to the original mark, (3) occurrence of blurring of discrimination or tarnishment of reputation; in particular, with respect to the degree of proof of 'blurring of discrimination or tarnishment of reputation', which is a constituent requirement of the trademark dilution of famous marks, it is reasonable to interpret the trademark dilution as concrete endangerment offense, neither harm-based offense nor abstract endangerment offense, and thus it should be considered that the crime is established if a specific realistic risk of blurring of discrimination or tarnishment of reputation occurs. Furthermore, in relation to the specific criteria of 'blurring of discrimination or tarnishment of reputation', it is necessary to comprehensively judge the degree of individual behavior in specific matters as a normative factor as well as the psychosocial viewpoint of the general public.

    Haegun Lee , Seong-Yoon Shin | 2019, 24(10) | pp.243~249 | number of Cited : 0
    Abstract PDF
    In this paper, we proposes a comprehensive analysis of the characteristics, selection procedures, and management perspectives of each university's financial support project, and derivation of a plan to integrate the information system of the university's financial support project. To this end, we analyze the current status of business operations before and after restructuring university financial support projects, and identified the characteristics, commonalities, and differences of each project. Individual projects are promoted segmentally, evaluation indicators and evaluation methods are different for each business, standardization is difficult, and in the absence of integrated governance, sympathy and will of the system integration of the government and the managing agency cannot be found. In order to integrate the system, the business management process must be integrated and standardized, and the system equipment such as budget category adjustment must be complemented, and a stable budget for system integration must be secured.

    Abstract PDF
    The purpose of the present study was to examine the causal relationship between aggression and mobile phone dependency among high school students and to test the mediating effect of self-esteem, and to draw out implications in order to encourage proper use of mobile phone. In this paper, we proposed a research model between aggression, self-esteem and mobile phone dependency. The present study analyzed the fourth, fifth, and sixth wave data from KCYPS 2010, using the structural equation modeling. The primary results were as follows. First, the effect of high school students’ aggression on mobile phone dependency was not significant. Second, high school students’ aggression had a significantly negative effect on self-esteem. Third, high school students’ self-esteem had a significantly positive effect on mobile phone dependency. Fourth, high school students’ self-esteem could be a significant mediator between aggression and mobile phone dependency. In conclusion, theoretical and practical suggestions were discussed in order to solve the problem of adolescents’ mobile phone dependency.

    Seong-Won Kim , Youngjun Lee | 2019, 24(10) | pp.267~278 | number of Cited : 6
    Abstract PDF
    As the importance of technology in education has increased, TPACK research has been actively conducted to promote the use of technology in class. However, due to the functional limitations of technology, the pre-service teacher had difficulty in using technology in class. Therefore, in this study, we have been studying the introduction of the programming language as a technology tool of TPACK. Using design-based research as a research method, we repeatedly developed an educational program, applied to pre-service teachers, and evaluated the effectiveness of the program. In the first study, pre-service teachers had difficulties in programming learning. To solve this problem, programming-based instruction and curriculum analysis were supplemented by educational programs. In the second study, pre-service teachers felt difficulty in using programming in teaching-learning, thus improving instruction design and reflection. The third study enhanced the programming development environment search to supplement programming learning and utilization.
