The purpose of this study is to classify the body types of obese men in their 50–60s and compare them with those of obese middle-aged men in their 30–40s. The 3D anthropometric data of obese men aged 50 to 60 years from the 6th Size Korea. The data are analyzed using SPSS 25.0 for Windows, and descriptive statistics, χ2 test, correlation analysis, and cluster analysis are used to classify obese body types. As a result of the study, five factors are extracted to determine body types, which are classified into three obese body types through cluster analysis. 1) a large physique and consequently large circumference and height; 2) A short upper body length, short height, and thick belly; 3) the lowest rate of obesity and relatively flat abdominal curve. For the 30–40s group, Type1 showed the highest rate at 55.6%, whereas for the 50s group, Type3 showed the highest rate at 49.3%, and for 60s group, Type2 showed the highest rate at 41.2%. The classification accuracy of the discriminant function for each type is 94.7%, indicating relatively high accuracy. Furthemore, the recently changed obese body type are analyzed by comparing it with the 3D anthropometric data of 8th Size Korea, which will contribute to the utilization of basic data for manufacturing apparel for obese men.

본 연구에서는 만성요통을 가진 여성노인의 체형 및 요부안정화를 위해 12주간 필라테스 운동 프로그램을 적용한 후 체형에 미치는 영향을 알아보고, 통증의 변화를 규명함으로써 노화를 늦추고 신체활 동 영역을 높일 수 있는 노인에게 적합한 운동 프로그램 개발에 필요한 자료를 제공하고자 하였다. 이에 3~5cm 중증도 통증범위의 만성요통을 가진 16명여성노인을 대상으로 주관적 통증척도지를 통해 실험집단 8명, 통제집단 8명을 단순무선표집(Simple Random Sampling)으로 선정하였다. 요부안정화 필라테스 운동 프로그램은 주 2회씩 총 12주간 50~60분간 실시하였으며, 1세트 종료 시 1분 휴식을 주는 방식으로 실시 하였다. 그 결과 첫째, 체형 및 통증에서는 경추 기울기에서 요부안정화 운동그룹의 경우 운동 전에 비해 감소하였으나 통제집단은 증가하였다. 둘째, 요부 통증의 결과 운동집단의 경우 운동에 비해 감소하였으나 통제집단은 증가하였다. 결론적으로 요부안정화 필라테스 운동은 만성요통을 가진 여성노인에게 있어서 통 증을 감소시킬 수 있는 프로그램으로 적용될 수 있으며, 체형을 개선시키는데 도움을 줄 수 있는 것으로 확인되었다.

본 연구의 목적은 체지방률이 높은 직장인 여성을 대상으로 리포사지(Lypossage)를 이용한 복부와 하지 체형 관리가 비만 관리 방법으로 타당한지 알아보고자 진행되었다. 연구 대상자는 총 35명으로 주관적인 비만 체형을 고민하는 사람을 무작위로 배정하였다. 리포사지는 9주동안 주 2회 실시하였으며, 단일 실험군은 리포사지 1Zone인 허리와 둔부, 허벅지 관리 50분을 실시하였다. 검사는 처치 전, 처치 4주 후와 9주 후 시행하였으며, 그룹 내 중재 기간에 따른 전ᆞ중ᆞ후 비교를 통해 종속변수에 미치는 효과를 알아보고자 하였다. 본 연구의 결과는 사전검사(0주), 4주후 검사, 9주 후 검사에 대한 세 기간과 집단의 상호작용으로 체중과 체지방량, 허리둘레, 허벅지 둘레 감소에 유의한 차이가 있었다(p<.05). 이러한 결과를 미루어 볼 때 리포사지는 직장인 여성의 하지 체형 관리에 긍정적인 효과를 보인 것으로 알 수 있었다

This study investigated the recognition and utilization status of food labeling and nutrition labeling, according to the body type recognition of university students. In a total of 351 subjects, the male subjects comprised of 25.8% belonging to the underweight awareness group, 46.3% normal weight awareness group, and 27.9% overweight awareness students. Among the female students, 29.2% belonged to the underweight awareness group, 36.6% were normal body weight, and 34.2% were the overweight group. When purchasing processed foods, the price (4.05 points), expiration date (4.03 points), and gross weight (3.88 points) were the most considered factors of the food labeling content (5 points) for all body shape recognition groups. The food labeling of canned foods was checked most by the underweight awareness group (p<0.05). For bread and snacks, the contents of food labeling were confirmed most by the normal weight awareness group and the overweight awareness group (p<0.001). For beverages, the normal weight awareness group checked more food labels (p<0.01). The underweight awareness group (55.2%) hardly checked the nutritional labeling, and 22.9% of these subjects did not check at all. Our results may provide the necessity to improve the incorrect eating habits of students, by evaluating differences between the cognitive body type and the actual body type by BMI.

This study utilized data to classify and characterize the body types of plus-size adult men aged in their 30s and 40s. Diversity is an important factor in the era of inclusive design, and discussion about size diversity to include the plus size should be accommodated. Data from 493 adult men classified as obese (with a World Health Organization criterion ≥25 BMI) were used for the analysis. The results of the study are as follows. Six independent factors were extracted using factor analysis for cluster analysis, which were then classified into five types. Type 1 (29.01%) was identified as body type I with the smallest degree of obesity. Type 2 (15.4%) was identified as body type Y with wide shoulders and a thin waist. Type 3 (14.2%) was the largest body volume (body type O), while the fourth (19.27%) identified as body type H has a large height and upper body. Lastly, type 5 (22.11%) has a long lower body and a slim abdomen, referred to as body type X. This study presents a basis for the development of various clothing sizes utilizing the body shape characteristics of plus-size men in their 30s and 40s. Follow-up research is needed to develop patterns for plus size men and to design various products.

The purpose of this study was to classify the upper torso body types of obese Korean adult women using the 7th Korea National Anthropometric Study data and compare the body type differences according to three age groups: 20s～30s, 40s～50s, and 60s. A total of 548 adult women whose BMI was in the obese range of 25 or higher and whose age ranged from 20s to 60s were selected from the anthropometric database. Twenty-nine body measurements related to torso and arm areas important for torso and sleeve pattern development were chosen. Five drop values by differences between bust, waist, and hip circumferences were also chosen for analysis. The number of obese women increased with age. The results revealed seven factors according to the factor analysis and three obese body types based on the cluster analysis. Body type 1 (47.3% of obese women) was characterized by narrow shoulders, a small or medium torso, and a straight waist. Body type 2 (42.4% of obese women) was characterized by a defined waist and a larger lower torso than upper torso. Body type 3 (10.3% of obese women), the largest obese body type among the three types, was characterized by a large bust, large abdomen area, and long upper torso. Women in their 20s to 30s were most likely to have body type 2, women in their 40s to 50s were evenly distributed between body types 2 and 3, and women in their 60s were most likely to have body type 1.

The apparel industry has recently been recognizing the important target market of middle-aged women. The aim of this study was to examine the anthropometric characteristics of US women of 46 to 65 years of age and identify distinctive body shape characteristics of US middle-aged women. A total of 1915 middle-aged women whose ages ranged from 46 to 65 were selected from the SizeUSA database. The age range was divided into two groups: 46-55 and 56-65. Twenty-four body measurements important for apparel development were chosen. Four factors—Girth Factor, Height Factor, Hip Drop Factor, and Bust Drop Factor—accounted for the US middle-aged women’s body measurements. The body shapes were classified into four body shapes, which were Y-Shape in the overweight range, S-Shape in the overweight range, H-Shape in the overweight range, and the A-Shape in obese range. H-Shape, which was the least-defined waist in relation to the bust and hips with a short height, existed more in older middle-aged women than in younger middle-aged women. Y-Shape, S-Shape, and A-Shape existed more in the group of younger middle-aged women than in the group of older middle-aged women. In addition, compared with the younger middle-aged women, older middle-aged women had narrower shoulders, a larger waist, thinner legs, and a longer distance between side neck to bust point. The findings from the current study may be applied in the apparel industry for developing clothing sizing systems for US middle-aged women.

The aim of this study was to use a 3D human body scanner to analyze the cross section of different body parts when a girdle is worn. Two types of girdles were selected as experimental garments: a standard type girdle (Garment A) and a high-waist type girdle (Garment B). Their sizes were 88 (S) and 94 (M). Ten female subjects in their twenties who wear girdles sizes 88 (S) and 94 (M) participated the experiment. Their bodies were scanned three times with the 3D human body scanner, before and after wearing experimental girdles. The data were collected by overlapping the cross sections of the 3D scanned body shape data. The space length was measured from the overlapped cross sections. The results show that human body silhouette are changed after wearing the compression type garments and the amount and place of the body change is different by style of garments. First, the waist girth shape became rounder. Second, there was a definite difference in space amount at abdomen girth between two types of girdle. The abdomen area was pushed toward the front after wearing the standard type girdle (A). The high-waist type girdle (B) pushed abdomen area toward the back. Third, there was clear difference at the hip area after wearing two types of girdle. The hip area pushed toward the front with the standard type girdle (A) and pushed toward the back with the high-waist type girdle (B).

해상 교량, 고층건물이나 라이저와 같은 세장 주상체의 설계 및 시공이 늘어남에 따라 높은 유속에 대한 동적 안정성 검토의 중요성이 부각되고 있다. 특히 교량구조물은 장대화와 함께 경량화가 진행되었고 지진, 바람 등과 같은 동적 하중에 대해서 진동하기 쉬운 구조물의 특징을 가진다. 구조물 주위를 흐르는 공기에 의해 추가적인 공기력들이 발생하게 되고 이로 인해 공기 흐름장과 물체의 운동 사이에 상호작용을 가져오게 되고 부가적으로 발생된 공기력이 음(-)의 감쇠력으로 유입 풍향에 직각방향인 진동에 작용하여 갤로핑(galloping)등과 같은 자발진동을 발생시킨다. 본 논문에서는 가상경계법을 이용하여 사각 단면, 팔각단면, 모서리가 둥근 사각단면 및 양쪽 모서리가 절단된 형태의 사각단면에 대하여 유동해석을 실시하고 Glauert-Den Hartog가 제시한 방법으로 단면에 대한 갤로핑 불안정성의 발생 가능성을 평가하였다.

본 연구에서는 고층 전단벽-골조 구조시스템의 효율적인 해석모델을 제안하였다. 전단벽-골조구조시스템은 휨거동하는 전단벽과 전단거동하는 골조로 구성된다. 그리고 전단벽-골조구조시스템의 변형형상은 골조와 전단벽의 상호작용으로 결정된다. 효율적인 해석모델에서는 이러한 거동특성을 반영되어야 하므로 골조와 전단벽을 분리하여 동적인 거동특성을 반영할 필요가 있다. 본 연구에서는 벽체부와 골조부를 분리하기 위하여 T형 강체를 전단벽의 위치에 대체하는 방법을 사용하였다. 분리한 벽체부와 골조부 각각의 등가모델을 구성한 후 결합시키는 방법으로 고층 전단벽-골조구조시스템의 등가모델을 완성하였다. 제안한 등가모델의 정확성과 효율성을 검증하기 위하여 고층의 전단벽-골조 구조물의 시간이력해석을 수행하였고, 그 결과 제안한 등가모델이 해석시간과 컴퓨터 메모리를 현저하게 줄이면서도 정확한 결과를 도출하였다.

The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 ㎝, and 67.0 ㎏ for the male students and 20.9 years old, 161.8 ㎝, and 53.4 ㎏ for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2, 169.2 kcal and 1, 846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1, 404.3 kcal/day and 1, 292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.

This study aimed to find the differences in weight control status and eating behavior of satisfied and dissatisfied female high school students regarding their own body shape. The participants consisted of 238 students at two female high schools in Nonsan-si, Chungnam-do in May of 2008. Self-assessment evaluated present body shape and ideal body shape they would like to have by providing silhouette drawings. The subjects were divided into two groups, 'satisfied' and 'dissatisfied', according to the differences between present body shape and ideal body shape. In the distribution of subjects according to body mass index, 100% of overweight, 97.0% of normal weight and 48.7% of underweight belonged to the dissatisfied group. There were significant differences in weight control and eating behavior between dissatisfied and satisfied groups in terms of frequency and reasons of conducting weight control behavior, body weight return after weight reduction, skipping breakfast and consuming fast food. The satisfied group was two times more likely to not conduct weight control behaviors compared to the dissatisfied group. The main reason for trying to control weight differed according to the group; the reason was feeling fat in the dissatisfied group and desiring to be healthy in the satisfied group. The percentage of subjects that returned to their original weights after weight reduction was 5 times higher in the dissatisfied group. The percentages of subjects that regularly skip breakfast and consume fast food were both higher in the dissatisfied group than in the satisfied group. The dissatisfied group responded 'eating alone' more frequently among nine binge eating behaviors compared to the satisfied group. Both groups, however, did not show any difference in overeating of meals, eating speed, intake frequency of regular meals, food preference, preferred cooking method, carbonated beverage intake and snack eating behavior. In summary, the dissatisfied group tried more unnecessary body weight reduction and had poor eating behavior. Accordingly, to correct the biased perception of body shape by the majority of female high school students, the values of our society should change toward the pursuit of beauty of health.

In this study, we modeled a ship or marine structure into a rectangular resistance body and tried to examine surrounding flow characteristics and pressure distributions behind the resistance body experimentally and investigated pressure characteristics by a 3-dimension numerical simulation. As a result, the reattachment point of the mainstream separated from the upper part and proceeding to the rear part was about x/H=6, but by the influence of the negative pressure area formed behind the resistance body and interference of the flow flowed in winding from left and right, the reattachment point of some flows was formed near x/H=1.33. The perpendicular velocity component behind x/H=0 varies in size with the recycle flow shapes formed from the influence of the resistance body, but generally it shows a negative distribution and there is a decreasing pattern as it goes to the down part. We verified the result of the calculation by comparing the velocity distribution of 3-dimension numerical simulation using a commercial software and the PIV(particle image velocimetry) measurements. In the numerical simulation results, the static pressure characteristic behind the resistance body was proportional to the inflow velocity, and the dynamic pressure shows a similar pattern with constant-velocity from the experiment.

The purpose of this study is to classify body shapes of aged women by using 3D body scan data. For the body shape analysis and classification, 3D body scan data of 270 aged women were used, and 16 main measurements consisting of a human body were used to conduct factor analysis, cluster analysis and discriminant analysis. The analysis were performed on all ‘the method using the absolute value’, ‘the method using index of height and weight’, and ‘the method using index of height,’ and according to the classification results, the method which categorizes body shapes best in terms of their shapes was adopted. As the factor analysis result using the numerical value of height to categorize the body shapes of the aged women, factor 1 was the thickness and width for the height, factor 2 was the height of the upper part of the body for the height, factor 3 was the height of hips for the height, and factor 4 was the height of belly for the height. When the body shapes were categorized with the deducted factors as variables, they were divided into two types. Type 1 was a short and fat body shape(▅ type) and 55.6% of the subjects were of this type. Type 2 was for the body shape whose vertical height, including weight, was long but all kinds of width and thickness were small, that is, tall and thin body shape(▋ type), and 44.4% of the aged women were in this case.

The study analyzed the body shape perception, weight control attitude, nutrition knowledge, and dietary habits of 529 high school students in Jeju surveyed from January 14-18, 2008 according to students' body shape satisfaction, with the aim of providing basic nutritional education data to aid in appropriate weight control for high school students. The data were analyzed by descriptive analysis, T-test, Chi-square test, ANOVA, and Pearson's correlation coefficients, using the SPSS Win 12.0 program. The body mass index (BMI) of subjects was in the normal range. With regard to weight distribution, 59.4% of subjects showed normal weight and girls were significantly more underweight than boys. More girls considered themselves to be fatter than boys and tended to be increasingly dissatisfied with their body shape. Both boys and girls were more interested in weight control for obesity and were significantly less satisfied with their body shape. Efforts at weight control and reduction had occurred significantly more often for girls than for boys. Dietary attitude scores were significantly higher in girls than boys. BMI positively correlated to weight control concern and nutrition knowledge positively correlated to dietary attitude. BMI negatively correlated to the body shape satisfaction, which in turn negatively correlated to food ingestion disorders. Therefore, it is necessary to develop a systematic nutrition educational program that can induce changes in dietary behavior and increase accurate perception and satisfaction of body shape.
