This study uses the "Sejong chronicles" ritual manual to investigate the movements and roles of provincial governors during the enshrinement rituals of the royal portrait, the official uniforms of the provincial governors in their roles, and the characteristics of the official uniforms system for local governors in the early Joseon Dynasty. The results of this study are as follows. Provincial governors who participated in the enshrinement rituals of the royal portrait were governors 'en route' and governors 'in destination'. The movements of the governor 'en route' followed the provincial borders, official residences, and neighboring provincial borders. The movements of the governor 'in destination' followed the provincial borders, the official residence, and jinjeon. The roles of the governors included the welcoming ceremony, the bow-down ceremony, the front guard, and the farewell ceremony. The governors 'en route' wore Jobok in the welcome ceremony, and a Sibok in the bow-down ceremony before the farewell. The governor 'in destination' wore Jobok in the welcome ceremony, and Jobok (or Sibok if Jobok was not available) in the bow-down ceremony before the farewell. The characteristics of the official uniforms system for local governors in the Joseon Dynasty were as follows. First, the governors wore different uniforms depending on the importance of the rituals in the early Joseon Dynasty. Second, the names of official uniforms Sang-bok and Si-bok were used interchangeably in the early Joseon Dynasty. Third, local governors were allowed to wear Sangbok (or Sibok) instead of Jobok.

This study compares the net effect of wearing different shoulder/arm armor systems on garment impediment perception and wearer acceptability. Two independent variables in this study were armor systems and shoulder/ arm movements. There were four armor systems of control garment and arm armor systems A, B, and C as well as five types of arm/shoulder movements, (shoulder flexion, should extension, shoulder abduction, shoulder horizontal flexion, and shoulder horizontal extension). Ten male volunteers wearing size medium battle dress uniform (BDU) with recent relevant military experience participated in this study. The volunteers performed shoulder/arm movements (while wearing each armor treatments) and completed the garment impediment perception as well as wearer acceptability scales. The body areas of neck side, shoulder top, and armscye front showed the highest frequency of reported impediments. Resistance to movement and localized pressure were the most frequently mentioned types of impediment. The armor system B had the most areas of impediment, and was rated as more restrictive than the control garment and armor system A for each movement. For wearer acceptability, no significant differences were found between the control garment and armor system A for all eight items; this indicated that subjects did not perceive a difference between wearing the control garment and armor system A. There was a trend for wearer acceptability to decrease from wearing the control garment to armor systems A to C to B.

In this paper, we measured partial discharge inception voltage(PDIV) and frequency spectra of UHF signal under following three cases, (1) a corona discharge due to a non uniform electric field for needle-plate electrode (2) a surface discharge caused by particles attached to a spacer in GIS, (3) free movements of particle in GIS. As a result of the experiment, it was revealed that the PDIV of Case (3) is higher than PDIVs of Case (1) and Case (2). It was also seem that UHF signal frequency spectra of one case are different from those of the other cases.

PEMFC has high potential for future development due to its high energy density, eco-friendliness, and high energy efficiency. When it becomes small, light and flexible, it can be competitive as an energy source for portable devices or flexible electronic devices. However, the use of hard and heavy materials for structural rigidity and uniform contact pressure transmission has become an obstacle to reducing the weight and flexibility of PEMFCs. This review intends to provide an example of the application of a new structure and material for lightweight and flexibility. As a lightweight PEMFC, a tubular design is presented and structural advantages through numerical modeling are explained. Manufacturing methods to realize the structural advantages and possibilities of tubular PEMFCs are discussed. In addition, the materials and manufacturing processes used to fabricate lightweight and flexible PEMFCs are described and factors affecting performance are analyzed. Strategies and structural improvements of light and flexible movements are discussed according to the component parts.

One of the methods to consider the effect of respiratory motion of a tumor target in radiotherapy is to establish a treatment plan with the internal target volume (ITV) created based on an accurate analysis of the target motion displacement. When this method is applied to intensity modulated radiotherapy (IMRT), it is expected to yield a different treatment dose distribution under the motion condition according to the IMRT method. In this study, we prepared ITV-based IMRT plans with conventional IMRT using fixed gantry angle beams, RapidArc using volumetric modulated arc therapy, and tomotherapy using helical therapy. Then, the variation in dose distribution caused by the target motion was analyzed by the dose measurement in the actual motion condition. A delivery quality assurance plan was prepared for the established IMRT plan and the dose distribution in the actual motion condition was measured and analyzed using a two-dimensional diode detector placed on a moving phantom capable of simulating breathing movements. The dose measurement was performed considering only a uniform target shape and motion in the superior-inferior (SI) direction. In this condition, it was confirmed that the error of the dose distribution due to the target motion is minimum in tomotherapy. This is thought to be due to the characteristic of tomotherapy that treats the target sequentially by dividing it into several slices. When the target shape is uniform and the main target motion direction is SI, it is considered that tomotherapy for the ITV-based IMRT method has a characteristic which can reduce the dose difference compared with the plan dose under the target motion condition.

Interactive Typography is a process where a user communicates by interacting with text and a moving factor. This research covers interactive typography using real-time response to a user's gesture. In order to form a language-independent system, preprocessing of entered text data presents image data. This preprocessing is followed by recognizing the image data and the setting interaction points. This is done using computer vision technology such as the Harris corner detector and contour detection. User interaction is achieved using skeleton information tracked by a depth camera. By synchronizing the user's skeleton information acquired by Kinect (a depth camera,) and the typography components (interaction points), all user gestures are linked with the typography in real time. An experiment was conducted, in both English and Korean, where users showed an 81% satisfaction level using an interactive typography system where text components showed discrete movements in accordance with the users' gestures. Through this experiment, it was possible to ascertain that sensibility varied depending on the size and the speed of the text and interactive alteration. The results show that interactive typography can potentially be an accurate communication tool, and not merely a uniform text transmission system.
