최근 실시간 가상 인물 애니메이션 시스템이 활발하게 보급되면서 피부모양을 자연스럽게 유지하면서도 고속으로 동작할 수 있는 인체 변형 방법이 요구되고 있다. 본 논문은 가상 인물을 구성하는 메쉬의 정점들을 회전 연산만으로 이동시켜 실시간에 인체를 변형하는 모델을 제안한다. 인체 변형의 처리과정으로 드로니 삼각화를 이용하여 각 정점의 회전 기준이 될 관절을 찾는 방법을 제시하고, 사원수 형태로 입력된 동작을 회전축의 방향에 따라 분해한 후 각 정점에 차등적으로 적용하여 피부를 자연스럽게 변형할 수 있음을 보인다.

Various literatures related computing of information processing have been recently shown the researches inspired from the remarkably excellent human capabilities which recognize and categorize very complex visual patterns such as body motions and facial expressions. Applied from human's outstanding ability of perception, the classification function of visual sequences without context information is specially crucial task for computer vision to understand both the coding and the retrieval of spatio-temporal patterns. This paper presents a biological process based action recognition model of computer vision, which is inspired from visual information processing of human brain for action recognition of visual sequences. Proposed model employs the structure of neural fields of bio-inspired visual perception on detecting motion sequences and discriminating visual patterns in human brain. Experimental results show that proposed recognition model takes not only into account several biological properties of visual information processing, but also is tolerant of time-warping. Furthermore, the model allows robust temporal evolution of classification compared to researches of action recognition. Presented model contributes to implement bio-inspired visual processing system such as intelligent robot agent, etc.

The purpose of this study is to analyze lower body types of women and provide information of body improvement of Korean adult female clothing product to ready-made clothes companies. As for the method of this study, it was conducted to measure the parts of the lower body of adult women at the age from 19 to 24 years, to analyze their characteristics and to categorize body types. For study, it was measured 150 female women in Seoul. Data was analyzed by used SPSS/WIN 19.0 Program. The results of this study are as follows. The means of the subjects in their early 20s are 159.8cm in height, 67.0cm in waist circumference, 91.6cm in hip and 52.0kg in weight. As a result of comparison with the $5^{th}$ Korean's human body size on measurement data, 20 items out of 33 items showed significant difference. Factor analysis was executed for 66 body measure and calculation items to draw the body construction factors of the women's lower body in their early 20s and principal component analysis was performed by orthogonal varimax rotation to clarify the measurement of factors and to derive explanatory factors. As result of Cluster analysis, body types' characteristics divide into 3 types. Type1 has tall and fat body form, type2 has shortest and curvy body form and type3 has average height and the most skinny body form.

The purpose of this study was to development a uniform shirt for high school boys aged 16-18 in the 7th Human Dimension Survey data of Size Korea. The upper body was analyzed to classify the upper body shape and to understand the characteristics of the body by type. Through this, we wanted to obtain the basic data necessary for the development of school uniform shirts. For data analysis, SPSS Ver. 26.0 program was used. In high school boys, there was no significant difference in height by age, but in width, thickness, length, circumference, shoulder slope, and weight, there were significant differences by age. The upper body types were categorized into four types: long shoulder skinny type, long upper body obese type, short shoulder normal type, and long shoulder normal type. Based on the size and body type data extracted from this study, it is thought that the development of uniform shirts with excellent fit should be realized through practical fashion development and construction of a size system.

In order to clarify spatial meaning of Meridian and Collateral theory(經絡學說) within the human body. Meridian Divergence(經別) was studied mainly on "Miraculous Pivot(靈樞) - Meridian Divergence section(經別篇)". Furthermore, the meaning of Meridian Divergence(經別) was investigated based on Symbolic Mathematical Study(象數學). Firstly, Meridian divergence(經別) is associated with brain and Viscera and Bowels(臟腑) which are located in the Central Palace(中宮, Zhong Gong). It draws that Meridian Divergence(經別) is a theory based on Nine Palace(九宮, Jiugong), the spatial theory of Symbolic Mathematical Study(象數學). In this system, Viscera and Bowels(臟腑) were included in Meridian and Collateral(經絡). Secondly, the Central Palace(中宮, Zhong Gong) imparts functionality to Nine Palace(九宮, Jiu Gong). Therefore, brain and Viscera and Bowels(臟腑) in Central Palace(中宮, Zhong Gong) supply Qi and Blood(氣血) to whole Meridian and Collateral(經絡) and also control each Meridian and Collateral(經絡) through Twelve Meridian Divergences(十二經別). Meridian and Collateral Theory(經絡學說) is the theory of Body space. The basic theory of Twelve Meridian Vessels(十二經脈), Three Yin and Three Yang(三陰三陽) signifies six areas of human body space. And Fifteen Collateral Vessels(十五絡脈) connect the six areas of the Twelve Meridian Vessles(十二經脈) through Six Harmonies(六合, liu He). In addition, Meridian Divergence(經別) is also based on Nine Palace(九宮, Jiu Gong). Thus, Meridian and Collateral(經絡) classifies and organically integrates the human body space that is filled with Qi and Blood(氣血) by applying the theories of Symbolic Mathematical Study(象數學). Recently presented Morphogenetic field hypothesis resembles Meridian and Collateral theory(經絡學說). However Meridian and Collateral theory(經絡學說) is considered to be the substantive concept that has relation to treatments based on Meridian points(經穴) which contain the spatial information of Meridian and Collateral theory(經絡學說).

For design research of teenagers' posture correcting shirt, postures of teenagers were analyzed and became the base of inventing suitable patterns. The subjects of this study were 198 of both female and male middle school students from the city of Seoul. Students' postures in classroom and length change of body surface were observed and analyzed; based on this, total of 5 postures was selected, and length changes of body surface were applied. The patterns in this study were designed with stretch material to help antagonism by muscle movements. Each fabric that was used in this study had 110% of stretch, 120~140% of stretch, and 150~170% of stretch. Both of one-way-fabric and duplex-fabric were used in this study, depending on application site.

Due to the development of information and communication, there is a rising interest on WBAN(Wireless Body Area Network) that maintain and check the human being health. According to the application of different quality of service and a special mechanism for transferring medical data are required in WBAN environment. In this paper, we proposed the new formed superframe that has CSMA/CA based TDMA scheduling and CSMA/CA used IEEE 802.15.4 in order to process emergency data and on-demand data in WBAN environment. We estimated performance of the proposed MAC protocol by compared performance of other MAC protocols that are IEEE 802.15.4 MAC protocl and Z-MAC protocol has contention access period based TDMA scheduling.

Because currently available wireless technologies are not appropriate for wireless body area networks (WBANs), the IEEE 802.15.6 standard was introduced by the IEEE 802.15.6 Task Group to satisfy all the requirements for a monitoring system that operates on, in, or around the human body. In this work, we develop an analytical model for evaluating the performance of an IEEE 802.15.6-based WBAN under saturation condition and a noisy channel. We employ a three-dimensional Markov chain to model the backoff procedure as specified in the standard. Probability generating functions (PGFs) are used to compute the performance descriptors of the network. The results obtained from the analytical model are validated by simulation results. Our results indicate that under saturation condition, the medium is accessed by the highest user priority nodes at the vast majority of time while the other nodes are starving.
