    A Study on college student’s cognition survey about CCTV in education facilities

    Lee,Yong-Hwan | Myoung-Woo Hong | 2012, 17(12) | pp.23~30 | number of Cited : 2
    Abstract PDF
    The purpose of this paper is to analyze various categories such as the recognition, expectation and acceptability of CCTV use in educational facilities by doing a survey on how college students think about the CCTV installed in educational facilities. For this research, diverse existing surveys regarding CCTV were examined, and the appropriate elements of survey questions were extracted and developed. Based on this method, we intend to complete a survey study hereafter on the change in perception regarding CCTV inspection. We made four hypotheses before the survey and the results of the survey are as follows: First, the expectations for CCTV’s ability to reduce crime were high. Second, the fears about being a victim of theft or violence crime were decreased. Third,there were a number of respondents who would weigh more on increased safety by installing a CCTV rather than be concerned that CCTV may lead to the violation of students' human rights. Fourth, there showed a difference in recognizing CCTV among three groups. Also, for the questions regarding the places where CCTV is installed, there were many negative opinions on its installation in the student convenient facilities. What we have achieved was not a simple survey which investigates the pros and cons about CCTV use, but a newly suggested way of survey, which enables us to test various hypotheses and figure out the changing perceptions on CCTV effectiveness in educational facilities with more efficiency.

    A Study on the Utilization and Control Method of Hybrid Switching Tap Based Automatic Voltage Regulator on Smart Grid

    박광윤 | 김정률 | Byung-gi Kim | 2012, 17(12) | pp.31~39 | number of Cited : 0
    Abstract PDF
    In this paper, we propose a microprocessor-based automatic voltage regulator(AVR) to reduce consumers’ electric energy consumption and to help controlling peak demanding power. Hybrid Switching Automatic Voltage Regulator (HS-AVR) consist of a toroidal core, several tap control switches, display and command control parts. The coil forms an autotransformer which has a serial main winding and four parallel auxiliary windings. It controls the output voltage by changing the combination of the coils and the switches. Relays are adopted as the link switches of the coils to minimize the loss. To make connecting and disconnecting time accurate, relays of the circuit have parallel TRIACs. A software phase locked loop(PLL) has been used to synchronize the timings of the switches to the voltage waveform. The software PLL informs the input voltage zero-crossing and positive/negative peak timing. The traditional voltage transformers and AVRs have a disadvantage of having a large mandatory capacity to accommodate maximum inrush current to avoid the switch contact damage. But we propose a suitable AVR for every purpose in smart grid with reduced size and increased efficiency.

    Donghui Yu | 양성훈 | 도재철 and 1other persons | 2012, 17(12) | pp.61~69 | number of Cited : 1
    Abstract PDF
    This paper shows results of the precise time comparison technique based on GPS code transfer in order to determine the UTC(Universal Time Coordinated) and generate TAI(International Atomic Time). CGGTTS(CCTF Group on GNSS Time Transfer Standards) which is generated by GPS timing receivers is used as the international standard format. For geodetic receivers which provide RINEX formats as GPS time transfer results, ROB(Royal Observatory of Belgium) developed a conversion program, r2cggtts, and have distributed the program to timing laboratories participating in TAI link all over the world. Timing laboratories generate the time comparison results of GPS code transfer by the program and send them to BIPM(Bureau International des Poids et Mesures) periodically. In this paper, we introduce the delay features generated while GPS code is transferred and the calibration methods of them. Then, we introduce the tropospheric delay and analyze the results of Saastamoinen model and NATO(North Atlantic Treaty organization)model. Saastamoinen model is the representative tropospheric zenith path delay model and NATO model is applied to the legacy r2cggtts program.

    License Plate Detection with Improved Adaboost Learning based on Newton’s Optimization and MCT

    이영현 | 김대훈 | Hanseok Ko | 2012, 17(12) | pp.71~82 | number of Cited : 1
    Abstract PDF
    In this paper, we propose a license plate detection method with improved Adaboost learning and MCT (Modified Census Transform). The MCT represents the local structure patterns as integer numbered feature values which has robustness to illumination change and memory efficiency. However, since these integer values are discrete, a lookup table is needed to design a weak classifier for Adaboost learning. Some previous research efforts have focused on minimization of exponential criterion for Adaboost optimization. In this paper, a method that uses MCT and improved Adaboost learning based on Newton’s optimization to exponential criterion is proposed for license plate detection. Experimental results on license patch images and field images demonstrate that the proposed method yields higher performance of detection rates with low false positives than the conventional method using the original Adaboost learning.

    Effective Image Segmentation using a Locally Weighted Fuzzy C-Means Clustering

    Nyma Alamgir | Jong Myon Kim | 2012, 17(12) | pp.83~93 | number of Cited : 1
    Abstract PDF
    This paper proposes an image segmentation framework that modifies the objective function of Fuzzy C-Means (FCM) to improve the performance and computational efficiency of the conventional FCM-based image segmentation. The proposed image segmentation framework includes a locally weighted fuzzy c-means (LWFCM) algorithm that takes into account the influence of neighboring pixels on the center pixel by assigning weights to the neighbors. Distance between a center pixel and a neighboring pixels are calculated within a window and these are basis for determining weights to indicate the importance of the memberships as well as to improve the clustering performance. We analyzed the segmentation performance of the proposed method by utilizing four eminent cluster validity functions such as partition coefficient (Vpc), partition entropy (Vpe), Xie-Bdni function (Vxb) and Fukuyama-Sugeno function (Vfs). Experimental results show that the proposed LWFCM outperforms other FCM algorithms (FCM, modified FCM, and spatial FCM, FCM with locally weighted information,fast generation FCM) in the cluster validity functions as well as both compactness and separation.

    Abstract PDF
    In many diagnostic and treatment procedures for prostate disease accurate detection of prostate boundaries in transrectal ultrasound(TRUS) images is required. This is a challenging and difficult task due to weak prostate boundaries, speckle noise and the short range of gray levels. In this paper a method for automatic prostate segmentation inTRUS images using support vectors and snake-like contour is presented. This method involves preprocessing, extracting Gabor feature, training, and prostate segmentation. Gabor filter bank for extracting the texture features has been implemented. A support vector machine(SVM) for training step has been used to get each feature of prostate and nonprostate. The boundary of prostate is extracted by the snake-like contour algorithm. The results showed that this new algorithm extracted the prostate boundary with less than 9.3% relative to boundary provided manually by experts.

    박용민 | 2012, 17(12) | pp.111~120 | number of Cited : 1
    Abstract PDF
    As the P2P System is a distributed system that shares resources of nodes that participate in the system, all the nodes serve as a role of server and client. Currently, although systematic,structured P2P systems such as Chord, Pastry, and Tapestry were suggested based on the distributed hash table, these systems are limited to log for performance efficiency. For this enhanced performance efficiency limited, the article herein suggests group routing algorithm. The suggested algorithm is a node-to-group routing algorithm which divides circular address space into groups and uses a concept of pointer representing each group, which is an algorithm where routing is performed based on pointer. To evaluate algorithm performance, a comparative analysis was conducted on average hops, routing table size, and delayed transmission for chord and routing, a signature algorithm in P2P systems. Therefore, enhanced performance is verified for comparative items from the simulation results.

    강형석 | 임송빈 | Oh,Young-Hwan | 2012, 17(12) | pp.137~148 | number of Cited : 2
    Abstract PDF
    In this paper, we proposed the location-aware coordinate routing algorithm for improving the performance of routing algorithm by using ZigBee in Smart Grid environment. A distributed address allocation scheme used an existing algorithm that has wasted in address space. The x, y and z coordinate axes from divided address space of 16 bit to solve this problems. However,coordinate routing does not take account of wireless link condition. If wiress link condition is not considered, when the routing table is updated, the nodes with bad link conditions are updated in the routing table and can be chosen as the next hop. This brings out the retransmissions because of received packet's errors. Also, because of these retransmissions, additional power is cons In this paper, we propose the location-aware coordinate routing algorithm considering wiress link condition, where reliable data transmission is made and the consumed enegy is minimize. and we compared and connected region and transition region of ZigBee location based routing in the aspect of average number of multi hops, subordinate packet delivery ratio, delay time, and energy consumption of proposed algorithm.

    A Hybrid Randomizing Function Based on Elias and Peres Method

    배성일 | 김민수 | 2012, 17(12) | pp.149~158 | number of Cited : 1
    Abstract PDF
    Proposed is a hybrid randomizing function using two asymptotically optimal randomizing functions: Elias function and Peres function. Randomizing function is an mathematical abstraction of producing a uniform random bits from a source of randomness with bias. It is known that the output rate of Elias function and Peres function approaches to the information-theoretic upper bound. Especially, for each fixed input length, Elias function is optimal. However, its computation is relatively complicated and depends on input lengths. On the contrary, Peres function is defined by a simple recursion. So its computation is much simpler, uniform over the input lengths, and runs on a small footprint. In view of this tradeoff between computational complexity and output efficiency, we propose a hybrid randomizing function that has strengths of the two randomizing functions and analyze it.

    Lee, Byung-kwan | Jeong Eun Hee | 2012, 17(12) | pp.179~185 | number of Cited : 0
    Abstract PDF
    This paper proposes a design of RSIDS(RST and SVM based Intrusion Detection System) using RST(Rough Set Theory) and SVM(Support Vector Machine) algorithm. The RSIDS consists of PrePro(PreProcessing) module, RRG(RST based Rule Generation) module, and SAD(SVM based Attack Detection) module. The PrePro module changes the collected information to the data format of RSIDS. The RRG module analyzes attack data, generates the rules of attacks, extracts attack information from the massive data by using these rules, and transfers the extracted attack information to the SAD module. The SAD module detects the attacks by using it, which the SAD module notifies to a manager. Therefore, compared to the existing SVM, the RSIDS improved average ADR(Attack Detection Ratio) from 77.71% to 85.28%, and reduced average FPR(False Positive ratio) from 13.25% to 9.87%. Thus, the RSIDS is estimated to have been improved,compared to the existing SVM.
