In this paper, we designed a coaxial dual camera incorporating two optical systems-one for the visible rays and the other for far-infrared ones-with the aim of capturing images in both wavelength ranges. The far-infrared system, which uses an uncooled detector, has a sensor array of 640×480 pixels. The visible ray system has 1,945×1,097 pixels. The coaxial dual optical system was designed using a hot mirror beam splitter to minimize heat transfer caused by infrared rays in the visible ray optical system. The optimization process revealed that the final version of the dual camera system reached more than 90% of the fusion performance between two separate images from dual systems. Multiple rigorous testing processes confirmed that the coaxial dual camera we designed demonstrates meaningful design efficiency and improved image conformity degree compared to existing dual cameras.

With the New media of present age we are living at, strongly entice consumers through various sensible technology and give influences on our life. They are visually formed but make us feel them as if formed tactile. The masses of today are meeting media through all the senses in daily life according to the spread of on-line media and in such course they want momentary and tactile share. Since appearance of mass society and cinema following such current, art has appealed to dispersive and tactile perception, and such public way of perception makes it possible to experience 'visual tactility' in daily life in accordance with the development of on-line game culture among others. The shock effects, given by editing of game animations which are produced for epic experience of on-line game, arouse tactility in addition to visibility. Under this assumption and on the basis of visual tactility theory as well as montage theory of image by Walter Benjamin, the research intends to explain that public tactile shock does not result from simple graphic effect but from montage effect and dispersive acceptance.

The development of a new hardware structure which can implement the viterbi algorithm efficiently is required for applications such as a software radio because the viterbi algorithm, which is an error correction code function for the second and the third generation of mobile communication, needs a lot of arithmetic operations. The length of K in the viterbi algorithm different from each standard, for examples, K=7 in case of IS-95 standard and GSM standard, and K=9 in case of WCDMA and CDMA2000. In this paper, we propose a new hardware structure of an adaptive viterbi decoder which can decode the constraint length in K=3~9 and the data rate in 1/2 ~ 1/3. Prototyping results targeted to Altera Cyclon EPIC20F400C8, shows that the proposed hardware structure needs maximum 19,276 logic elements and power dissipation of 222.6 mW.

Background: The development of lung cancer results from the interaction between genetic mutations and dynamic epigenetic alterations, although the exact mechanisms are not completely understood. Changes in DNA methylation may be a promising biomarker for early detection and prognosis of lung cancer. We evaluated the serial changes in genome-wide DNA methylation patterns in blood samples of lung cancer patients. Methods: Blood samples were obtained for three consecutive years from three patients (2 years before, 1 year before, and after lung cancer detection) and from three control subjects (without lung cancer). We used the MethylationEPIC BeadChip method, which covers the 850,000 bp cytosine-phosphate-guanine (CpG) site, to conduct an epigenome-wide analysis. Significant differentially methylated regions (DMRs) were identified using p-values <0.05 in a correlation test identifying serial methylation changes and serial increase or decrease in ${\beta}$ value above 0.1 for three consecutive years. Results: We found three significant CpG sites with differentially methylated ${\beta}$ values and 7,105 CpG sites with significant correlation from control patients without lung cancer. However, there were no significant DMRs. In contrast, we found 11 significant CpG sites with differentially methylated ${\beta}$ values and 10,562 CpG sites with significant correlation from patients with lung cancer. There were two significant DMRs: cg21126229 (RNF212) and cg27098574 (BCAR1). Conclusion: This study revealed DNA methylation changes that might be implicated in lung cancer development. The DNA methylation changes may be the possible candidate target regions for the early detection and prevention of lung cancer.

This study was aimed to analyze the disparities of 3D stereoscopic images in four well-known American animation movies. After Avatar (2009), lots of stereoscopic movies were developed in Korean 3D production. Almost all 3D productions in Korea, however, focus on the display images or TV series animation yet. In order to make many well-made Korean stereoscopic 3D animations in future, analyzing and comparing the disparities of 3D stereoscopic images is necessary and even mandated. First, I chose 40 cuts from each four American stereoscopic 3D feature films, including Despicable me 2, Epic, Monster University, and Turbo. According to the classifications of shot angles by Vineyard (2008), secondly I analyze the 23 different angular disparities of 3D stereoscopic images and displayed in tables. Demonstrated shot angle disparities in each scene would provide numerical information to animators how to design and make the 3D stereoscopic images. Making successful stereoscopic 3D feature film will be a huge turning point in the Korean animation field in future. This study would be a first trial to seek a new method to set ahead an outlook of numerical values of 3D stereoscopic images for better visual effects.

The Rare Isotope Science Project (RISP) at the Institute for Basic Science (IBS) constructs the rare isotope accelerator facility in South Korea. Since the accelerator control system uses various Ethernet-based devices and equipment, it is essential to build a unified Network-based control system. Because of the complexity of the accelerator facility, it will be a challenge to install a device in a proper location where the device could react quickly and exactly with respect to network security. In this report, we will present early study on Simple Network Management Protocol (SNMP) that tests various Ethernet-based devices out on an ideal network configuration in order to find an optimal location for each Ethernet-based device. Moreover, we will discuss future plan to integrate SNMP into Experimental Physics and Industrial Control System (EPICS) that is distributed soft real-time control systems for scientific instruments such as a particle accelerators, telescopes and other large scientific experiments.

The KSTAR Current Lead System(CLS) with network based real-time distributed control system is implemented using an EPICS as a middle-ware software. The current lead system transfers current from magnet power supplies to superconducting magnet system and simultaneously supply the coolant to maintain superconducting state. To control the CLS at main control room an EPICS IOC server is installed in local control area. Using this server, it is able to be controlled and monitored the system in main control room through operator interface(OPI) which uses "caget" to read status and "caput" to write command with a unique name called PV. The EPICS IOC is developed using "ether-ip" driver to communicate with PLC. Also we achieved satisfactory results in operation and stability aspects from a long period commissioning test.

This study investigated and analyzed Sadanggut for General Namyi, Agisee Gutdang in Haengdang-dong, Dodanggut in Bonghwa Mountainto examine the type and characteristics of official hats for shaman's costumes based on Seoul village gutas a spiritualistic shaman revealing the divinity of music for gutthrough singing, dancing, divine material and official hats. Commonly worn official hats were Goggal(conical hats), Jeonlip(soldier's felt hats), and Heuklip(black hats) for Seoul village gut as the object of thisstudy. Each official hat had a close relationship with subjects for divinity and musical meaning for gut. Julip(Red hats), Jokduri(bride's headpiece), helmets, Iksubgwan(King's official hat), and Daesu(Queen's a big wig with various hairpins) were also worn. Official hats worn for Seoul village gutwere understood to symbolize divinity and raise authority and dignity to the public through aggressive appearance, exaggeration and splendor. Concretely, official hats at Seoul village gut first had roles to materialize the divinity of each music of gut. Second, recognized as a part of performance or traditional culture in present day, aggressive official hats were favored to supply splendid attraction and maximize scenes of divined heroic epic poem in gut. Third, for Seoul village gut, colors and silhouettes of modern traditional costumes were reflected pursuing partial change and focused on exaggeration and splendor to express the mirth and festival of gutwhile maintaining traditional costumes.
