Usefulness and clinical availability for surgery efficiency were evaluated by conducting pre-operative planning with a model manufactured by desktop 3D printer by using clavicle CT image. The patient-customized clavicle fracture model was manufactured by desktop 3D printer of FDM wire laminated processing method by converting the CT image into STL file in Open Source DICOM Viewer Osirix. Also, the model of the original shape before damaged was restored and manufactured by Mirror technique based on STL file of not fractured clavicle of the other side by using the symmetry feature of the human body. For the model, the position and size, degree of the fracture was equally printed out. Using the clavicle model directly manufactured with low cost and less time in Department of Radiology is considered to be useful because it can reduce secondary damage during surgery and increase surgery efficiency with Minimal invasive percutaneous plate osteosynthesis(MIPO).

We suggest a method which solves the planar, two vehicle collision reconstruction problem. The method based on the Principle of impulse and momentum determines the pre-impact velocity components from Post-impact velocity components, vehicle Physical data and collision geometry. A novel feature is that although the impact coefficients such as the restitution coefficient and the impulse ratio are unknown, the method can estimate automatically the coefficients and calculate the pre-impact velocity components. This reverse calculation is important for vehicle accident reconstruction, since the pre-impact velocities are unknown and Post-impact Phase is the starting Point in a usual collision analysis. However. an inverse solution is not always Possible with the analytical rigid-body impact model. Mathematically, one does not exist under the common velocity condition. On the other hand, our method has a capability of reverse calculation under the condition if the absorbed energy during the collision process can be estimated using the crush profile. To validate the developed collision reconstruction a1gorithm, we use car-to-car collision test results. The analysis and experimental results agree well in the impact coefficients and the Pre-impact velocity components.

In this study, clothing items recorded in Nappyemulmok (納幣物目) and Ugwimulmok (于歸物目) in the early 20th century were examined. These clothing items were recorded on the lists of goods for wedding gifts from the 1910s to the 1930s. A large quantity of these lists were organized into eight categories by analyzing the fabrics of each item of clothing. Representative fabrics used for skirts and Jeogori (such as Myeongju, 明紬) were used widely. Jeoksam was mostly made with ramie fabric. Pants mostly used cotton such as Dangmok, Mumyung, and calico, with some use of silk. Gojaengi mostly used cotton such as Dangmok, Mumyung, and calico, with some use of ramie. Danui (單衣) used silk fabrics such Pparinseu, Myeongju, and Gyoju for decorative features that were revealed when rolled up. Naeui (內衣) is believed to be the closest underclothes to the body, and Mumyung was mostly used. Dangmok and calico were used for the Yodae (腰帶) and fabrics such as silk, Nobangju, and JuhangNa were used for outdoor use. This type of categorization is significant, as it can be used as academic evidence to verify and reproduce the clothing of the time by identifying fabrics, colors, and characteristics of certain items of clothing. Lastly, it is expected that the analysis of clothing will provide theoretical data in the same way that movies, dramas, and museum exhibitions feature modern traditional weddings.

Obstructive sleep apnea (OSA) among sleep disorders is one of relatively common diseases. Patients can be checked for the disease through sleep polysomnography. However, as far as he diagnosis of OSA using polysomnography (PSG) is concerned, many practical problems such as an increasing number of patients, expensive testing cost, discomfort during examination, and the limited number of people for testing have been pointed out. Accordingly, for the purpose of substituting PSG researchers have been actively conducting studies on OSA diagnosis based on machine learning using bio signals. In this regard, we review a rich body of existing OSA diagnosis studies applying machine learning techniques based on bio-signal data. As a result, this paper presents a novel taxonomy of the reviewed studies and provides their comprehensive comparative analysis results. Also, we reveal various limitations of the studies using the bio signals and suggest several improvements about utilization of the used machine learning methods. Finally, this paper presents future research topics related to the application of machine learning techniques using bio signals.

Through a consideration of the contralateral collateral needling(繆刺) from "Neijing", the conclusions are as follows. The contralateral collateral needing is defined as a disordered state, and also as the pricking bloodletting method. Unlike the seasonal deficiency pathogen(虛邪), which are affected by the four seasons, the subject of the contralateral collateral needling is the extra pathogen(奇邪), which is the cause of the extra disease(奇病), therefore the treatment should be different from the general. The contralateral collateral needling is generally used when a pain is generated from the veins(絡) by an external pathogen(邪). However, it can be used as the treatment for an emotional disorder, such as flight or sorrow, or a body constituent(身形) disorder caused by internal parts of the five viscera. Although the contralateral collateral needling(繆刺) and the contralateral meridian needling(巨刺) share the left and right cross treatment(右取左, 左取右) in common, but they are different in every aspect, as the causes, transmutation, location, and feature of disease, relation of qi and blood, and location and method of needling(刺鍼). The medical procedure of the contralateral collateral needling is collateral needling(刺絡) the parts of blood collaterals(血絡) or bruising(痏) well points(井穴) of the end of the both sides of limbs, and using the left and right cross treatment when the former methods are not making any progress. The symptoms of contralateral collateral needling are head, chest, and abdomen pains, and they are treated at the end of the limbs. The bloodletting method(刺絡法), extracting a little amount of blood at well points or blood collaterals, or the collateral vessel pricking therapy(瀉血法), extracting a lot of blood by using cupping(附缸), for example, are contemporary successions of the collateral needling(絡刺), the leopard-spot needling(豹文刺), and the contralateral collateral needling.

A new coinage which calls a modern was appeared variously by values, taste, feature of lifestyle and the meaning of a new coinage has influence in the change of lifestyle. Particularly a popular star is a person who situates in the center of a new coinage, his role, behavior, and appearance have great influence in the birth of a new coinage. He is a fashion leader as well as the object of fashion imitation to the new generation being sensitive for fashion. As his fashion is appeared with important fashion icon in fashion market, fashion companies have developed actively star marketing marking him as an advertising model. Therefore, because the fashion trends of a popular star introduce season's fashion trends and can be important factor forecasting fashion behavior of consumer, this study aims at analysis for fashion trends of a popular star including a public entertainer. The dates of this study were collected by TV drama, internet, and magazines, etc. The fashion trends were divided into feminine fashion trend, sexy fashion trend, tomboy fashion trend, and retro fashion trend. Feminine fashion trend was based on feminity but it was classified in masculine look, simple look, chic look, and natural & romantic look according to the standard of a transformation of feminine image. Sexy fashion trend was divided into two sexy images according to the method wrapping oneself in a dress and the method exposing a specific body part. Tomboy fashion trend could be the immature boyish style which concealed bust or hip or pelvis symbolizing feminity. Retro fashion trend could be style being based on 1980's style and Y line. Fashion items as leggings, baby doll dress, tunic style, dot pattern, garsonne look were come into fashion.

This article proposes a design and implementation methodology of a gesture-based interface for augmented reality games. The topic of gesture-based augmented reality games is a promising area in the immersive future games using human body motions. However, due to the instability of the current motion recognition technologies, most previous development processes have introduced many ad hoc methods to handle the shortcomings and, hence, the game architectures have become highly irregular and inefficient This article proposes an efficient development methodology for gesture-based augmented reality games through prototyping a table tennis game with a gesture interface. We also verify the applicability of the prototyping mechanism by implementing and demonstrating the augmented reality table tennis game. In the experiments, the implemented prototype has stably tracked real rackets to allow fast movements and interactions without delay.

모바일향 90nm DRAM을 개발하기 위하여 비대칭 채널 구조를 갖는 Recess Channel Array Transistor (RCAT)로 cell transistor를 구현하였다. DRAM cell transistor에서 junction leakage current 증가는 DRAM retention time 열화에 심각한 영향을 미치는 요인으로 알려져 있으며, DRAM의 minimum feature size가 점점 감소함에 따라 short channel effect의 영향으로 junction leakage current는 더욱 더 증가하게 된다. 본 실험에서는 short channel effect의 영향에 의한 junction leakage current를 감소시키기 위하여 Recess Channel Array Transistor를 도입하였고, cell transistor의 채널 영역을 비대칭으로 형성하여 data retention time을 증가시켰다. 비대칭 채널 구조을 이용하여 Recess Channel Array Transistor를 구현한 결과, sub-threshold 특성과 문턱전압, Body effect, 그리고, GIDL 특성에는 큰 유의차가 보이지 않았고, I-V특성인 드레인 포화전류(IDS)는 대칭 채널 구조인 transistor 대비 24.8% 정도 증가하였다. 그리고, data retention time은 2배 정도 증가하였다. 본 실험에서 얻은 결과는 향후 저전압 DRAM 개발과 응용에 상당한 기여를 할 것으로 기대된다.
