In this study, the relationships between the interior space of the upper class residence of Korean late Chosun dynasty and human dimensions based on their life styles of that era are analized. As an object of the study, the interior space of Yunkyungdant in Changduk palace is selected. The major analytical frame works of this study are : the analysis of Space-Human Body System, the analysis of Space-Objects-Human Body System, and the analy-sis of Space-Objects-Human Body System, and the analy-sis of Space-Objects-Life Activities of Human Body System. As a result, it was verified that there are certain quantitative relationships between the interior space of the residence and the human dimensions of Koreans lived up to their life styles and activities of Chosun dynasty era, specialized as 'Confucian life style'.

In this work the possibility of obtaining a rectilinear motion of bodies partially or totally submerged without using propellers is evaluated. The system propulsion is based on a pair of counter rotating masses that generate the thrust. The fluid-body system has been schematized in order to carry out a very simple model. Using this model an evaluation of the body motion along a longitudinal direction was performed. The motion equations of the system were written and integrated. The external forces applied to the body depend on its velocity in relation to the water. These forces were obtained by fluid dynamic simulations. Regarding the mechanical configuration suggested, the results obtained show that a certain displacement of the body along a fixed direction is obtainable.

최근 건강과 관련된 다양한 시스템들에 대한 연구가 진행되고 있다. 이에 반해 사용자의 신체 정보를 정확하게 분석하고 이에 따른 정보를 제공해주는 시스템들은 개발 단계이거나 정확도가 미흡한 수준이다. 이를 해결하기 위해 본 논문에서는 사용자의 신체 정보를 분석하는 알고리즘을 제시하고 이를 기반으로 한 피트니스 시스템을 제안한다. 사용자의 신체 정보를 분석하는 알고리즘은 사용자의 신장과 체중을 분석하여 BMI(Body Mass Index) 지수와 BMR(Basal Metabolic Rate) 수치를 계산한다. 제안하는 시스템은 계산된 BMI 지수와 BMR 수치를 바탕으로 사용자에게 적합한 운동량을 추천해줄 수 있을 것으로 사료된다.

The aim of this study is to develop a model of layering system for future soldier system. Future soldier has been supposed to carry various digital devices embedded into the combat uniform. The combat uniform must be developed to be fit to soldier's body and movement, and can be felt comfortable to soldier. The Uniform must be studied in ergonomic and physiological component because it is different from the present one. It has many devices inside, so there are some unknown barriers to set the devices on to the body. For making the ergonomic aspect of future combat suits clear, the movement of the body was researched. The size of arms(3 parts), torsos(4 parts), and legs(3 parts) of people were measured by movement. Many dots were drawn on the testees' bodies every 3cm. Each time they made compulsory poses, the distances between dots be measured and analyzed. For making the physiological aspect of future combat suits clear, the thermo-map and sweating map of body were made. The 3 maps - movement, thermo and sweating- were overlapped. The devices for future soldier were arranged on the overlapped map considering relations between devices. The final layering system developed on the arrangement of devices.

The purpose of this study was to develop middle school girl's' school uniform sizing system according to their body types. The data collected with anthropometric measurements from 390 middle school girls aged 12-15 years old was analyzed using t-test, ANOVA, factor analysis and cluster analysis. A new sizing system was developed in accordance with each of the 2 body-type clusters. The analysis of two-way distribution of 'height-bust girth' and 'height-waist girth' was conducted for the girls of the first grade, which is the time when they purchase their school uniforms. The interval of sizing system was defined in consideration with the most efficient distribution of the body sizes utilizing Loss Function. This study also provided Reference-Sizes and Growth-Allowance Measures for each sizing system to help pattern drafting and clothing construction of the uniform manufacturers. The cover ratio of sizing system proposed by this study was higher when compared with that of the National Agency for Technology and Quality and uniform manufacturing companies, Thus, the result of this study is expected to make up the current sizing system of the school uniform.

The wireless sensor network (WSN) based ECG and body temperature measuring system for ubiquitous health-care were designed and developed. The system was composed of a wireless sensor network node, base station and server computer for the continuous monitoring of ECG signals and body temperatures of patients at home or hospital. ECG signal and body temperature data, important vital signals which are commonly used in clinical and trauma care, were displayed on a graphical user interface (GUI). The data transfer from sensor nodes on patients' body to server computer was accomplished through a base-station connected to a server computer using Zigbee compatible IEEE802.15.4 standard wireless communication. Real-time as well as historical, ECG data of elderly persons or patients, can also be retrieved and played back to assist the diagnosis. The ubiquitous health care system presented in this study can effectively reduce social medical expenses, which will be increased greatly in the coming aging society.

오늘날 자전거는 레저용으로 각 회사에서 다양화되고 있다. 각 자전거 메이커로부터 다품종의 자전거가 판매되고 있지만, 구매자가 그 중에서 자신의 신체에 적합한 자전거의 정보를 얻는 것은 쉬운 것은 아니다. 따라서 대부분 구매자의 신체치수를 이용하여 자전거를 구매하고 있다. 이와 같은 방법을 이용하는 것은 표준 신체치수에 의하여 자전거의 치수를 결정하는 방법이다. 그러나 이 방법에 의하여 자전거를 구입하였을 경우 구매자의 신체에 적합한 자전거라고 볼 수가 없다. 본 연구에서는 구매자가 직접 본인의 신체에 맞도록 최적 설계시스템을 조절하여 자전거를 설계한다. 그리고 퍼지제어기를 이용한 주행 시험 장치에서 주행시험을 한다. 그 결과를 이용하여 구매자의 신체에 적합한 자전거인가를 판단할 수 있는 최적 자전거 설계시스템을 연구한 것이다.

Parametric bodies reproduce the actual shape of human body parts and should be convenient for general users to change size to judge the visual fit of clothes on-line. In this study, three parametric bodies(i.e. I, C, D ) were compared to verify the accuracy of the provided body dimensions and reproducibility to a target model. To compare reproducibility, the 20s female standard virtual model developed for an apparel industry by Korean agency for technology and standards is used. The investigation of existing parameters showed that the numbers and kinds of parameters provided by each program were different with some errors in notation; in addition, some of virtual body dimensions went beyond the maximum allowable error. The result of changing each parametric body to the 20s female standard body showed that D, C, I in order produced better reproducibility for body dimensions. There were different levels of protrusion and concavity in the virtual cross sections and virtual longitudinal sections despite the small differences in body dimensions and cross sectional areas; in addition, some parametric body was not bilateral symmetry. The results of this study can be used as basic information in the standardization of a virtual model used in a virtual garment program.

The purpose of this study is to create a 3D avatar from 3D human body shape data using the CLO 3D virtual clothing program and to verify the feasibility of avatar production using the virtual clothing system for verifying size and shape. The research method was to select one virtual representative model that is the closest to the mean size of each body item for each age group. Using the 3D human body scan shape of a 40-69 years old male was applied to the CLO 3D virtual wearing system. Using the CLO 3D Avatar conversion menu, we verified the feasibility of creating a 3D avatar that reproduces the human body scan shape. In the dimension comparison between the 3D avatar and the fictitious representative model, the dimension difference was noticeable in height, circumference, and length. However, as a result, the converted 3D avatar showed less than a 5% difference in most human dimensions. In addition, since the body shape and posture were reproduced similarly, the utilization of the avatar was verified.

Recently, the finite element absolute nodal coordinate formulation (ANCF) was developed for the large deformation analysis of flexible bodies in multi-body dynamics. This formulation is based on the finite element procedures and the general continuum mechanics theory to represent the elastic forces. In this paper, a computation method of dynamic stress in flexible multi-body dynamics using absolute nodal coordinate formulation is proposed. Numerical examples, based on an Euler-Bernoulli beam theory, are shown to verify the efficiency of the proposed method. This method can be applied for predicting the fatigue life of a mechanical system. Moreover, this study demonstrates that structural and multi-body dynamic models can be unified in one numerical system.
