The eldest son of the crown prince is very important social status next to the crown prince deciding fundamentals of a state in Chosun dynasty which laying stress royal authority. Accordingly, Chakbong(冊封) of the eldest son of the crown prince has been done independently like as Chakrei(冊禮) of the crown prince. The existig record of Chakrei(冊禮) of the eldest son of the crown prince. The existing record of Charkrei(冊禮) of the eldest son of the crown prince are Hyunjongwangseon(顯宗王世孫), Euisoseson(懿昭世孫), Youngjowangseson(英祖王世孫), Hungjongwangseson(憲宗王世孫) of 4 books for Chakreidogameuigue(冊禮都監儀軌) being preserved in Kyujangkak(奎章閣). The transition of classified clothes are stated on Wangse sonchakreidogameuiguebanchado(王世孫冊禮都監儀軌班次圖) for Chakrei(冊禮) of the eldest son of the crown prince. Its details are as below. Finally, there is no changes in constitution of the costume of the eldest son of the crown prince Chakrei(冊禮) called as Ssanggodong(雙童髮)·Gongjungchak(空頂 )·Ojangbok(五章服) on documentary records depsitefo no explanation of Banchado(班次圖). Secondly, The classified clothes of the eldes sion of the crown prince Hcakreibanchado(冊禮班次圖) are on . We have acknowledged that Kwanmo(冠帽) of Dangbukwanwon(堂部官院) has been changed from Heugrib(黑笠) to Samo(紗帽) since Youngjowangseson(英祖王世孫), Euibok(衣服) from Chungpo(靑袍) to Nokdanryung(綠團領), the costume of Euijangsu(儀仗手) from Chunggun(靑巾) to Whangchorib(黃草笠) and changed again to Hongpimoja(紅皮帽子), Chungeui(靑衣) changed to Hongeui(紅衣). Also we know that Kwanmo(冠帽) of Kyogun(轎軍) has been changed to Pimoja(皮帽子) with high top, Chungeui(靑衣) changed to Hongeui(紅衣). The costume of Byulgam(別監) has been changed from Nokgun(綠巾) to Jogun( 巾), Nokpo(綠袍) changed to Pimoja(皮帽子) with high top, Chungeui(靑衣) changed to Hongeui(紅衣). The costume of Byulgam(別監) has been changed from Nokgun(綠巾) to Jogun( 巾), Nokpo(綠袍) changed to Hongpo(紅袍), that of Suri(書吏) changed from Chungeui(靑衣) to Huekeui(黑衣). Accordingly, the transition of costume color to red stands for the briliance. Thirdly, regarding the constitution of the eldest son of the crown prince Chakrei(冊禮), that of Euisoseson(懿昭世孫) & Youngjowangseson(英祖王世孫) are same for Unggolta(態骨朶), Youngjagi(令字旗), Keumdungja(金 子), Eundungja(銀 子), Mojul( 節), Jaksun(雀扇), Chungkae(靑蓋), Chungyangsol(靑陽率). In case of Hunjongseson(懿昭世孫), Baktakgi(白澤旗) is added. On Youngjowangseson(英祖王世孫), Chungilsol(靑日率) and Kiringi(麒麟旗) are added. However, we know that the constitution of the eldestson of the crown prince Hunjong(憲宗) Chakrei(冊禮) is quite different that of previous constitution. i.e. : Hongae(紅蓋), Baktakgi(白澤旗), Samkaggi(三角旗), Kagdangi(角端旗), Byukbonggi(碧鳳旗), Jujakgi(朱雀旗), Kuemdungja(金 子), Eundungja(銀 子), Eunribgwa(銀立瓜), Kuemhwanggwa(金 瓜), Eunhwhanggwa(銀 瓜), Kuemwolbu(金鉞斧), Bongsun(鳳扇), Huegkae(黑蓋). Also the kinds of Eujanggi(儀仗旗) are various which are similar to the constitution of The Crown Prince(世子) Chakrei(冊禮).

This study is a study dealing with the empirical test of standardized multimedia disaster warning broadcasting linked with the next-generation prediction and warning platform and the disaster warning additional data service of terrestrial UHD broadcasting. The next-generation prediction and warning platform used in the demonstration test complies with the CAP-based TTA standardization standard, and the UHD disaster warning additional data service complies with the AEAT standard. As a result of the experiment, when a standardized CAP disaster warning message is issued and delivered to a broadcasting company, a system was established so that it is automatically converted to AEAT, a UHD disaster warning additional data message, and transmitted. The receiver unit was configured by connecting a set-top capable of receiving disaster alert data and a TV with an HDMI cable. When a disaster is announced, the set-top displays the AEAT message on the TV broadcasting screen, customized to the priority of the disaster and the area where it is issued. In addition, incoming messages are displayed in a language suitable for user settings among 5 languages. Additional multimedia functions such as images and alarm sounds could also be linked. In particular, it was confirmed that the receiver message was displayed within 3 seconds of issuing the disaster alert, enabling prompt delivery of the disaster alert.

This paper presents an augmented reality (AR) based rehabilitation exercise system to enhance the motor function of the hands for the paretic/hemi-paretic patient. The existing rehabilitation systems rely on mechanical apparatus for palsy rehabilitation, but we aim to use the rehabilitation system at home with easy configuration and minimized equipment by the computer vision based approach. The proposed method evaluates the interaction status of the fingertip action by using the position and the contact of the fingertip markers. We obtain the 2D positions of the fingertip markers from a single camera, and then transform the 3D positions from the calibrated camera space by using an ARToolKit marker. We adopt simple geometric calculation by the conversion of the 2D interest points into the 3D interaction points for the simple interactive task in AR environment. Some experimental results show that the proposed method is practical and simply applicable to the applications with personal AR interaction.

In this paper, we designed a tabletop display which enables two viewers each to see a different image simultaneously within his/her defined viewing zone. In order to construct the designed viewing zones, we found the basic design conditions for a parallax barrier with a commercial LCD panel. As the viewing zones for two viewers are formed with only two view-point design, the interval between the center positions of each viewing zone and the width of each viewing zone are small compared to designed values. We analyzed the primary cases, introduced two modified design methods to enlarge the interval and the width of the viewing zones, and simulated their characteristics. As designed with six unit view-point and each viewing zone of each viewer is formed with a merged view-point, we found that adequate interval and width of viewing zones can be made, and we verified it in comparison with the tabletop display module that we fabricated.

In this work, we investigated the recently proposed phase-contrast x-ray imaging (PCXI) technique, the so-called single grid-based PCXI, which has great simplicity and minimal requirements on the setup alignment. It allows for imaging of smaller features and variations in the examined sample than conventional attenuation-based x-ray imaging with lower x-ray dose. We performed a systematic simulation using a simulation platform developed by us to investigate the image characteristics. We also performed a preliminary PCXI experiment using an established a table-top setup to demonstrate the performance of the simulation platform. The system consists of an x-ray tube ($50kV_p$, 5 mAs), a focused-linear grid (200-lines/inch), and a flat-panel detector ($48-{\mu}m$ pixel size). According to our results, the simulated contrast of phase images was much enhanced, compared to that of the absorption images. The scattering length scale estimated for a given simulation condition was about 117 nm. It was very similar, at least qualitatively, to the experimental contrast, which demonstrates the performance of the simulation platform. We also found that the level of the phase gradient of oriented structures strongly depended on the orientation of the structure relative to that of linear grids.

Salmonellosis caused by chicken consumption has been a critical issue in food safety worldwide, including in Korea. The probability of illness from consumption of chicken was simulated in study, based on the recipe of Dakgalbi, a commonly eaten chicken dish in Korea. Additionally, the processing stage at slaughterhouses to decrease Salmonella concentration in broilers was modeled to explore its effect on the likelihood of illness. A Monte Carlo simulation model was created using @RISK. Prevalence of Salmonella in chickens at the retail stage was found to be predominantly important in determining the probability of illness. Other than the prevalence, cooking temperature was found to have the largest impact on the probability of illness. The results also demonstrated that, although chlorination is a powerful tool for decreasing the Salmonella concentration in chicken, this effect did not last long and was negated by the following stages. This study analyzes the effects of variables of the retail-to-table pathway on the likelihood of salmonellosis in broiler consumption, and also evaluates the processing step used to decrease the contamination level of Salmonella in broilers at slaughterhouses. According to the results, we suggest that methods to decrease the contamination level of Salmonella such as chlorination had little effect on decreasing the probability of illness. Overall, these results suggest that preventing contamination of broiler with Salmonella must be a top priority and that methods to reduce the concentration of Salmonella in broilers at slaughterhouses hardly contribute to safe consumption of Salmonella-contaminated chicken.

Automatic test case generation for testing an embedded software is considered. Existing tools for test case generation such as finite state machine or mutant test usually adopt top down approach and depend upon graphical transition and decision table, which makes it difficult to find out where the bugs exist. Also it is hard to describe the special features of embedded systems such as concurrent execution of individual components. Most of embedded systems interacts with the real world, receiving signals through sensors or switches and sending output signals to actuators that somehow manipulate the environment. Embedded software controls the entire system based on the logics such as interpreting the sensor inputs and making the actuators to start or stop their intended operation. This study proposes an automatic test case generation procedure that tests the system starting from the control logics of sensors, switches and actuators and then their concurrent execution controls, and finally the entire system operation. Such a stepwise approach makes it easy to generate test cases to tell where the bugs of embedded software exist.
