The e-navigation in IMO(International Maritime Organization) has been developed as a strategy for user oriented service followed by HEAP(Human Element Analysing Process) to assess the solutions in view of human ergonomics. Although IMO already had an interim guideline for human element assessment, it did not include appropriate human elements for user-oriented assessment, therefore there should be a need for revising the human elements of current guideline for ergonomic assessment of e-navigation. We have developed user-oriented human element checklist, threat elements caused by human external condition and error elements originated by human itself in line with the e-navigation development concept of user-based approach.

Electromagnetic analysis to design unclonable PUFs with frequency-dependant materials with Debye dispersion was considered. To simulate FDTD calculations consider that 1-D problem of pulsed plane wave traveling in free space normally incident on air-silicon material interface on dielectric substrate. The pulse traveling wave at a vacuum-medium interface was reflected, and transmitted wave was dissipated. As a result, 1-D PUF modeling with Debye dispersion on dielectric substrate structure can be applied and FDTD calculation for PUF modeling is a good approximation.

In this paper, we propose an intelligent surveillance system using fuzzy contrast and HOG method. This surveillance system is mainly for the intruder detection. In order to enhance the brightness difference, we apply fuzzy contrast and also apply subtraction method to before/after the surveillance. Then the system identifies the intrusion when the difference of histogram between before/after surveillance is sufficiently large. If the incident happens, the camera stops automatically and the analysis of the screen is performed with fuzzy binarization and Blob method. The intruder is detected and tracked in real time by HOG method and linear SVM. The proposed system is implemented and tested in real world environment and showed acceptable performance in both detection rate and tracking success rate.

Park, Hye-Ran ; Kim, Wu-Woan ; Jang, Sang-Dong ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1173~1178
DOI : 10.6109/jkiice.2012.16.6.1173
In the Cluster-Based Routing Protocol (CBRP) a cluster header in each cluster should be elected. The cluster headers consume energy much more than other nodes because they manage and operate all of mobile nodes in their cluster. The traditional CBRP elects a cluster header without considering the remaining electric energy of each node. So, there exists problems that the cluster header has short average lifetime, and another cluster header should be elected again frequently. In this paper, we propose the improved protocol which prolongs the lifetime of the cluster header and enhances the stability of the path. In order to achieve this, when a cluster header is elected in a cluster, the remaining electric energies of all the nodes are compared with one another, and the node with the highest energy is elected as the cluster header.

In this paper, we propose an algorithm that recognizes human activity patterns using the human body`s joints and the information of the joints. The proposed method extracts the object from inputted video, automatically extracts joints using the ratio of the human body, applies block-matching algorithm for each joint and gets the motion information of joints. The proposed method uses the joints to move, the directional vector of motions of joints, and the sign to represent the increase or decrease of x and y coordinates of joints as basic parameters for human recognition of activity. The proposed method was tested for 8 human activities of inputted video from a web camera and had the good result for the ration of recognition of the human activities.

DOI : 10.6109/jkiice.2012.16.6.1187
This paper describes a method to detect QR-code finders by four-direction scanning. The finder recognition is the first step in the QR-code recognition. If the finder is missing, QR-code recognition fails. The existing QR-code recognition method has a problem that the recognition performance decreases for perspectively distored images. To overcome the problem, we introduce four-direction scanning and a candidate set image to accurately detect QR-code finders. Using morphological operations detect the QR-code finder in the candidate set image robustly. To show the effectiveness of our method, we compared our method with the well-known existing method. The experimental result indicates that the proposed method is superior to the existing method in terms of the finder recognition performance.

According to the rapid development of cell phone and camera industry, all of electronic products obtain small-size, high-performance and variety. Therefore, PCB also obtains high-integration, multi-layers and high-specification rapidly. Among the digital cameras which are continuously evolved and developed, the market of mirror-less camera and hybrid digital camera is continuously increased because of the customer`s request for small-size and weight lightening, except for DSLR camera. Therefore, the difficulty of PCB design is gradually increased and design L/T is longer according to the high-specifications, low-current and high-performance components. This thesis suggests the method to reduce L/T for PCB design applied to the reduction of digital camera`s developing period and manufacturing period.

Efficient Method for Exchanging Data between DDS Middlewares based on Adaptive Packet Transmission
Ahn, Sung-Woo ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1229~1234
DOI : 10.6109/jkiice.2012.16.6.1229
In this paper, we analyze the problems that the DDS middleware, which is a standard data-centric communication interface, uses the fixed packet transmission method by the pre-defined protocol for exchanging data packets. The packet transmission method selected in a fixed manner cannot handle appropriately the increasing of resource overhead in an environment where the load of the DDS network changes dynamically. If the load on the node and network exceeds the threshold, the performance of the packet transmission may be degraded rapidly. This results in a failure of ensuring the real-time characteristic of DDS middleware. To solve this problem, we propose the scheme of the adaptive packet transmission for adjusting the transmission method in real-time based on the overhead on the DDS network.

DOI : 10.6109/jkiice.2012.16.6.1235
In this paper, each driving motor for leg joints on a robot is controlled by estimating the direction of the legs measuring each joint angle and attitude angle of robot. We used quadruped working robot named TITAN-VIII in order to carry out this experimental study. 4 load cells are installed under the bottom of 4 legs to measure the pressed force on each leg while it`s walking. The walking experiments of the robot were performed in 8 different conditions combined with duty factor, the length of a stride, the trajectory height of the foot and walking period of robot. The validity of attitude control for quadruped walking robot is evaluated by comparing the pressed force on a leg and the power consumption of joint driving motor. As a result, it was confirmed that the slip-condition of which the foot leave the ground late at the beginning of new period of the robot during walking process, which means the attitude control of the robot during walking process wasn`t perfect only by measuring joint and attitude angle for estimating the direction of the foot.

Kim, Kang-Chul ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1242~1249
DOI : 10.6109/jkiice.2012.16.6.1242
This paper proposes a metastability-free synchronization method and a mesochronous synchronizer for NoC. It uses the clock transmitted from TX as a strobe and solves the metastability problem by selecting one of rising or falling clock edge depending on the sampling value in RX when the phase difference between clocks is under a metastability window. The logic simulation results show that it works without metastability under
phase difference in the synchronizer that a fault is inserted. The mesochronous synchronizer has a simple control logic and is suitable for NoC.

Eo, Ji-Hun ; Kim, Sang-Hun ; Jang, Young-Chan ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1250~1259
DOI : 10.6109/jkiice.2012.16.6.1250
In this paper, a time-domain comparator is proposed for a successive approximation (SA) analog-to-digital converter (ADC) with a low power and high resolution. The proposed time-domain comparator consists of a voltage-controlled delay converter with a clock feed-through compensation circuit, a time amplifier, and binary phase detector. It has a small input capacitance and compensates the clock feed-through noise. To analyze the performance of the proposed time-domain comparator, two 1V 10-bit 200-kS/s SA ADCs with a different time-domain comparator are implemented by using 0.18-
1-poly 6-metal CMOS process. The measured SNDR of the implemented SA ADC is 56.27 dB for the analog input signal of 11.1 kHz, and the clock feed-through compensation circuit and time amplifier of the proposed time-domain comparator enhance the SNDR of about 6 dB. The power consumption and area of the implemented SA ADC are 10.39
and 0.126 mm2, respectively.
Subthreshold Characteristics of Double Gate MOSFET for Gaussian Function Distribution
Jung, Hak-Kee ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1260~1265
DOI : 10.6109/jkiice.2012.16.6.1260
This paper have presented the change for subthreshold characteristics for double gate(DG) MOSFET based on scaling theory and the shape of Gaussian function. To obtain the analytical solution of Poisson`s equation, Gaussian function been used as carrier distribution and consequently potential distributions have been analyzed closely for experimental results, and the subthreshold characteristics have been analyzed for the shape parameters of Gaussian function such as projected range and standard projected deviation. Since this potential model has been verified in the previous papers, we have used this model to analyze the subthreshold chatacteristics. The scaling theory is to sustain constant outputs for the change of device parameters. As a result to apply the scaling theory for DGMOSFET, we know the subthreshold characteristics have been greatly changed, and the change of threshold voltage is bigger relatively.
Device Degradation with Gate Lengths and Gate Widths in InGaZnO Thin Film Transistors
Lee, Jae-Ki ; Park, Jong-Tae ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1266~1272
DOI : 10.6109/jkiice.2012.16.6.1266
An InGaZnO thin film transistor with different gate lengths and widths have been fabricated and their device degradations with device sizes have been also performed after negative gate bias stress. The threshold voltage and subthreshold swing have been decreased with decrease of gate length. However, the threshold voltages were increased with the decrease of gate lengths. The transfer curves were negatively shifted after negative gate stress and the threshold voltage was decreased. However, the subthreshold swing was not changed after negative gate stress. This is due to the hole trapping in the gate dielectric materials. The decreases of the threshold voltage variation with the decrease of gate length and the increase of gate width were believed due to the less hole injection into gate dielectrics after a negative gate stress.

Kim, Hui-Gyeong ; Yoo, Hoon ;
Journal of the Korea Institute of Information and Communication Engineering, volume 16, issue 6, 2012, Pages 1273~1278
DOI : 10.6109/jkiice.2012.16.6.1273
In this paper, we introduce modified integer transforms for lossless image compression and evaluate their performances for two-dimensional transforms. The two-dimensional extensions of the modified integer transforms show different performances in terms of coding efficiency and computational complexity. Thus, we measure performances for two-dimensional separable transforms and a two-dimensional non-separable transform. The separable modified integer transform used in H.264, the modified integer transform using the lifting scheme, and the non-separable transform in JPEG XR are evaluated in this paper. Also, experiments and their results are given. The experimental results indicate that the modified integer transform using the lifting scheme shows the best performance in terms of compression efficiency.

DOI : 10.6109/jkiice.2012.16.6.1291
UML is a semantically rich language, but it is difficult to ensure consistency of the diagrams you have written. Therefore, in this paper, we propose cross checking rules to improve consistency between UML diagrams, especially between UML static diagram and dynamic diagram. We use metamodels in order to more clearly reflect interactions of UML elements in the checking rules and use OCL(Object Constraint Language) to accurately represent the checking rules. By comparing with the well-formedness rules of UML specification, we focus on consistency of UML diagrams. And we derive metamodels of static diagram and dynamic diagram, analysis the relationships of UML diagrams and finally, we test the usability of derived rules through a case study.

ZSphere of ZBrush can be added to the canvas, and most of all, added to the existing ZSphere as mobile geometrical objects. For example, arms can be produced out of the globoid in the progress of an intermediate step. characters with multiple limbs can be produced easily in this way. With Zsphere, several Child Spheres can be produced out of single Sphere, then these can be parents spheres, and can connect other Child Spheres. In this paper, by making each form through these processes, 3D characters were modeled to shape easily and rapidly. Since 3D objects can be added, rotated, and moved, they can interact smoothly with Z-depth of campus. To place these objects on the screen, paint, build fixed perspective image, smerge pixols and transform 3D objects, diverse transforming tools and sculpturing tools were used. The characters were designed in the way that first, the finished 3D characters were transformed into poly, then each side was restructured rapidly with Topology.

The current situation and problems of sensory console games was analyzed focusing on the Nintendo `Wii.` In order to develop the limitation of contents that lean strongly towards sports and fail to offer diversity one step further into glocal cultural contents, a solution of applying `Bollywood`, which has a main musical format, is presented. Bollywood is a unique cultural code of India which can stimulate the purchase desires of consumers with its exotic freshness in third countries, and can be used to lead sales of a new form of game culture that is familiar yet in a new format in the 1.1 billion population Indian market. The political, social and economic codes of Bollywood are examined in this study in addition to cultural contents and codes that include Bollywood to develop contents that are not foreign to their culture.

The submarines reach their weakest point when they sail on the surface to operate snorkel and periscope. At this period, however, there lies a high possibility that the submarines are detected by non-acoustic sensors such as radars, IR signatures, and human observations. In this paper, the non-acoustic stealth was adopted on the mast and periscope of submarines so as to overcome their vulnerability of being easily detected in this given situation. First of all, the non-acoustic detection sensors were investigated and the stealth methods were analyzed. And multi-layered structures consisting of RAM layer, IR layer, and Camouflage layer were proposed on the surface of the submarine. As a results, multi-layered structure was suggested with 3~5 mm of a magnetic material such as ferrite for RAM layer, 1~2 mm of ceramic or nickel for IR layer, and sea-blue paint for Camouflage layer.
