The purpose of this study is to calculate the size of unit space of the classroom in elementary school. The curriculum of Elementary school has changed since 1960. It has been reflected the architectural plan of classroom of the nationwide elementary school. However the Ministry of Education repealed the statute about the facilities of the schools on September in 1997 and the new education curriculum-the 7th curriculum-demands various activities in the classroom. So we need to another size of unit space of the classroom in elementary school because the size of unit space will affect the quality of education. This study represent that the size of unit plan is based on the size of human body, education curriculum, the number limit of classroom and teaching tools. It's generally known that a part of human body size has an invariable proportion with human's status. In this study, regression analysis is used to find out a part of the body-size of Korean. Through this analysis, status, age and weight remarkably relate with a part of human body-size. Then the size of unit plan of the classroom is calculated by the part of body-size and the type of desk arrangement.

The purpose of this study was to study the degree of consciousness and satisfaction of body cathexis of high school girls' lower bodyshape. The subjects in this study were 296 high school girls. The results were as follows : 1. The degree of satisfactions of girth items in lower part of the body were influenced by real body size than ideal body size. But the degree of satisfaction of weight was influenced by ideal body size and height was influenced by real size body. 2. The high school girls thought ideal body shape was tall in height, long in leg, slim in girth and light in weight. Therefore, they wanted to have slimmer, longer, and lighter body size than real body size. 3. The high school girls were more satisfied with lean body type than with standard body type or with obesity body type. Therefore they wanted to be lean body type.

이 논문은 인체치수와 교구에 기초한 일반교실평면크기의 산정에 관한 연구이다. 초등학교의 교육과정은 1960년대 이래로 지금까지 7차에 걸쳐 변화되었으며, 그러한 교육과정의 변화는 초등학교 일반교실의 평면에 반영되어 왔다. 새로운 교육과정인 제7차교육과정은 학급 내에서 다양한 활동을 수용할 것을 요구하게 되었다. 또한 교육부는 1997년 9월 학교시설기준을 폐지하였고, 일반교실의 규모가 교육의 질에 영향을 미치는 것을 고려할 때, 초등학교 일반교실의 크기에도 변화가 필요하게 되었다. 일반적으로 알려진 바와 같이, 각 부위별 인체치수는 키, 나이, 몸무게와 밀접한 관계가 있다. 이 연구에서는 한국인의 각 인체부위 치수를 산정하는데 있어서 키, 나이, 몸무게를 독립변수로 한 회귀분석이 사용되었다. 그 다음 각 부위별 인체치수, 교구 및 책상배열에 따라 일반교실의 크기를 산정하였다.

In this paper, we suggest the method for constructing parameterized human body model which has any required body sizes from 3D scan data. Because of well developed 3D scan technology, we can get more detailed human body model data which allow to generate precise human model. In this field, there are a lot of research is performed with 3D scan data. But previous researches have some limitations to make human body model. They need too much time to perform hole-filling process or calculate parameterization of model. Even more they missed out verification process. To solve these problems, we used several methods. We first choose proper 125 3D scan data from 5th Korean body size survey of Size Korea according to age, height and weight. We also did post process, feature point setting, RBF interpolation and align, to parameterize human model. Then principal component analysis is adapted to the result of post processed data to obtain dominant shape parameters. These steps allow to reduce process time without loss of accuracy. Finally, we compare these results and statistical data of Size Korea to verify our parameterized human model.

The purpose of this study is to present the method to select optimal size for the industrial products which are closely related to human's body size. For this purpose, human factors such as body characteristics, body features, and preference in product selection which needs to be considered in setting standards were analyzed. This analysis is to select optimal size to minimize losses caused by the difference of size between demand by the customers and supply from the manufacturers. Using loss function, repetitive calculation process algorithm by using bisearch method was applied in selecting the sizes of demand and supply which minimize the total expected losses. For cumulative normal distribution probability, IMSL routine DNORDF was used. In case study, comparison has been made between the result which was calculated using presented algorithm and the results calculated by the process currently used by KS and ISO by measuring aged women's body size in human factors side and sorting them through the factor analysis and cluster analysis for feature factor extraction. Thus, they can be used as a basis for establishing industrial product standards.

This study explored elderly American women's body satisfaction and clothing consciousness with the methods of survey and body measurement. To that end, I first investigated their self-perception of body size and body satisfaction and also the relationships between those, along with the relationships between body measurements and body satisfaction. Then, I analyzed the differences in elderly women's body satisfaction and clothing consciousness among different body type groups. For the last, I examined the degree of their body thinness or obesity and ideal body size in order to explore the standard for ideal body shape among elderly women. Elderly American women were satisfied with most of their body parts except waist circumference and weight. Body satisfaction with stature, weight, and hip circumference was correlated to both size perception and body measurement. Body satisfaction with thigh circumference and leg length was correlated to size perception, and also that with waist circumference and neck length to body measurement. Size perception showed differences among body types, but body satisfaction did not show notable differences among body types. There were significant differences between real size and ideal one. Elderly American women thought that clothing was important in their everyday life.

An anatomically detailed elderly human body model is under development. Using the anthropometric database of domestic nation-wide size survey, SizeKorea, a standard size and shape of 50th %tile elderly was constructed. Through the local recruitment process, a male volunteer with 71 years of age, 163cm of height and 63kg of weight has been selected. The exterior (skin) and interior (skeleton and organ) geometries were acquired from whole body 3D laser scan and various medical images such as CT, X-ray, and Ultrasonic of the volunteer. A particular attention has been paid into the combining process of exterior and interior geometries especially for joint articulation positions since they were measured at different postures (sitting vs. supine). A whole ribcage of PMHS which possessed similar anthropometry and age of standard 50th %tile elderly was prepared and dissected for the precise gauge of cortical rib bone thickness distributions. After completing the morphological construction of elderly human body, the finite element modeling will be processed by meshing elements and assigning mechanical properties to various biological tissues which reflect the aging effect.

Recently, as various examples of machine learning have been applied in the healthcare field, deep learning technology has been applied to various tasks, such as electrocardiogram examination and body composition analysis using wearable devices such as smart watches. To utilize deep learning, securing data is the most important procedure, where human intervention, such as data classification, is required. In this study, we propose a model that uses a clustering algorithm, namely, the K-means clustering, to label body fat according to gender and age considering body size aspects, such as chest circumference and waist circumference, and classifies body fat into five groups from high risk to low risk using a convolutional neural network (CNN). As a result of model validation, accuracy, precision, and recall results of more than 95% were obtained. Thus, rational decision making can be made in the field of healthcare or obesity analysis using the proposed method.

The purpose of this study is to analyze the pattern of the present flight suit, to select variables of human body and key dimensions for making pattern of the flight suit, and to decide the most appropriate size of human body and rate of ease for designing an overall flight suit. For analyzing the pattern of flight suit, we used "M95Special" (men ; chest circumference 92-97 cm ; height : above 177 cm), which was indicated as the standard of the Ministry of National Defense. We analyzed general appearance and the actual dimensions of the pattern of the flight suit. As a result of analyzing the pattern, flight suit was front-opened overall style which had a flat collar with rounded edges, two-pieced sleeves with lower height of the sleeve's cap, 3cm-width belt on the waist and 8 pockets. To decide the most appropriate size of human body, we selected 20 variables of human body in the 359 variables of the Size Korea by referring the previous studies. The 20 variables of human body were 9 circumferences (chest, waist, hip, neck, armscye, wrist, thigh, knee, and ankle), 9 lengths (stature, back interscye fold, waist back, crotch height, crotch, body rise, arm, outside leg and total), and 2 breadths (biacromial and chest). We drew out the size of 20 variables from the Size Korea and US Army anthropometry data and decided the most appropriate values from the drawn data for applying to the pattern of flight suit.
