The purpose of this study is to classify the upper body of women into several kinds of somatotypes, using the method of Surgical Tape and making their shells. The subjects are 53 females 30 to 39 years-old. Fifty-three anthropometric data are measured per shell of bodysurface; six somatotype factors are obtained through principal component analysis and orthogonal rotation by the method of Varimax, Somatotype of women's upper body is achieved by cluster analysis, using the standardized factor score as an independent variable and the FASTCLUS of SAS by Kmeans. The results are as follows: 1. The number of the factors which explain the somatotype is six and those factors comprise 76.12 percent of total variance. Factor 1: related to the size of shape in the front of upper body Factor S: related to the size of shape in the back of upper body Factor 3: related to the type of the upper chest over the chest circumference line Factor 4: related to the length of·the upper body Factor 5: related to the part of the neck Factor 6: related to the type of the lower chest under the chest circumference line 2. Cluster analysis results in classification of upper body into five clusters. Cluster L: the length is the largest and the circumference is small. The part of waist is the largest and widest among surface areas. Cluster 2: Slender body line from chest to waist is characteristic. The length is longer. The part of upper and lower chest is larger among surface areas. Cluster S: the circumference is the smallest and armhole is small. The length and surface area are small. Cluster 4: the circumference and armhole is the largest. The length is the smallest. Cluster 5: the circumference is average and the length is a little long. The body line(silhouette) from chest to waist is curved slightly.

Objective: The present study is intended to develop an improved bus seat armrest design by evaluating various bus armrest designs from ergonomic aspects. Background: An ergonomic armrest design which considers the sitting postures and body shapes of passengers can improve the convenience and comfort of a bus seat. Method: Subjective satisfaction of each of five design dimensions (length, width, height from seatpan, shape, and angle) was evaluated for seven bus seat armrest designs in various sizes and shapes by 58 participants (28 males and 33 females) using a 7-point scale (1: very dissatisfied, 4: neutral, and 7: very satisfied). Improved bus seat armrest designs adjustable in length and rotatable to the left or right (sliding and rotating armrest, SRA) with a concave, flat, or convex shape of the upper part were developed by considering the preferred design features and the body size and shape in sitting posture and needs of passengers and then compared with a conventional armrest. Results: A bus seat armrest with a wide width (40~50mm), a long length (360mm), a lower height (213mm), and a curved shape was found significantly preferred in terms of comfort. The proposed armrest designs (SRA-convex, SRA-flat, and SRA-concave) improved satisfaction by 46~62% for length suitability, 184~216% for width suitability, 205~214% for angle suitability, 138~181% for contact area suitability, and 49~64% for height suitability, 138~174% for comfort, and 93~111% for overall satisfaction. Conclusion: The preferred design features and passengers' needs of bus seat armrest were identified and the SRA designs were recommended for better usability. Application: The ergonomic design process of bus seat armrest employed in the present study can be applied to designing armrests in various vehicles for better convenience and comfort.

The aim of this study is to provide fundamental data on the development of ready-to-wear clothing appropriate for the lower body types of male students who play sports in college. The study was conducted by means of targeting 151 male sports majors between $18{\sim}27$ years of age. Characteristics of the respondents were ascertained by means of questionnaires and an evaluation of a total of 36 lower body features. The results of the study are as follows. 1. A comparison of anthropometric measurements with the National Anthropometric Survey of Korea (1997) revealed that the main characteristics of the lower somatotypes of male sports college students are large circumferences and developed muscles of the lower body. 2. Sports were classified into the following five categories : soccer, bodybuilding, wrestling, judo, and taekwondo. In particular, bodybuilding students demonstrated a somatotype with an increased circumference, depth, and width of the thigh and lower body. 3. Somatotypes were classified into 3 types by means of a cluster analysis employing S factors. Type 1 somatotype exhibits a large circumference in the lower body. Type 2 is a lower somatotype of a middle size. Finally, Type 3 encompasses a smaller group in weight and circumference with a developed calf and ankle. 4. Each group was evaluated using a discriminatory analysis as a check to see if the groups had been discriminated with accuracy. The total accuracy rate was 96.0%.

The purpose of this study is to provide basic data reflecting body characteristics for production of briefs by classifying lower body types of women in their 40s, 50s and 60s. The results are as follows: First, measurements for height-related items decreased while the measurements for width and depth items increased with age. However, 'hip width' and 'hip depth' items showed no significant differences among the age groups. In addition, no visible differences appeared in the length items among the age groups but 'waist to hip' and 'outside leg' lengths showed decreasing values according to age. Second, four factors were established from the factor analysis: 'obesity level around waist and abdomen', 'vertical length of the lower body', 'thickness and obesity level of lower limbs', and, 'size and shape of buttocks'. Lastly, cluster analysis resulted in the classification of the four factors mentioned above. Type 2 appeared the most, representing women in their 40s~60s. Type 1(n=257) was referred as 'slender with a short lower body', Type 2(n=443) as 'plump with short lower body', Type 3(n=224) as 'slender with long lower body', and Type 4(n=199) as 'obese around abdomen and lower limbs'.

This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

The study has an objective of providing the basic data for the bodice basic pattern that is highly appropriate after classifying the torso shapes of women in 60s. In order to classify the torso shape, 200 women in 60s that reside in Seoul were investigated for 52 tests. The factor analysis produced total of 6 factors. Factor 1 tended to be posture of upper part of torso and shape of shoulder. Factor 2 was an element of silhouette and Factor 3 was vertical size of lower part of torso and side silhouette. Factor 4 showed to be width and thickness of torso, Factor 5 was shape of neck, and Factor 6 appeared to be sagging of belly and buttocks. Therefore, it can be known that posture, silhouette, shape of neck and shoulder, sagging of belly and buttocks, and etc. are important factors for classification of the torso shape of women in 60s. Through a cluster analysis, each torso shape was classified into 4 types and each type showed information on size, shape, and posture clearly. Type 1 showed percentage of 24.2%, and values of height and weight showed to be average. Also, the body shape hardly had any curve with high shoulder at the Posture of upper body, and they had saggy stomach and buttocks. 43.5% of them were involved in Type 2 and they were short and overweighted. They were comparatively large in width compared to the height with no curves. Type 2 had the largest percentage and this can be said to be the special shape of women in 60s. People of Type 3 were short and overweighted just like Type 2 and all the sizes were similar to those of Type 2 or bigger. The posture is right posture and 21.7％ fall into this type and there is no body curve. This type is the shortest and most overweighted type, and it is a torso shape with right posture just like Type 4. Type 4 is a torso shape with tallest height and least weight. The percentage was the smallest(10.6％) and the width was smaller than any other type but the height was the tallest. The body curve is very clear and they have thin body but big buttocks so it can be said that the people of this type have the best silhouette. Type 2 that had the highest percentile is short and overweighted so it can be said that Type 2 is the representative torso shape of women in 60s.

Although several supplementary foods are available for pregnant and lactating women, there is a need for foods able to maintain a woman's beauty without any changes in body shape. In this study, four questionnaires about nutrition management, skin care, body shape, and the intent of purchasing beauty supplementary foods, were prepared for an online survey (http://pms8011.wixsite.com/project). A total of 95 answers from 293 women were classified into four groups, based on age, income, occupation, and skin type. The data were statistically analyzed using SPSS/WIN Program 22.0. The significances of the F-value analyzed by one-way ANOVA and the differences within the groups were verified by Scheffe's method. All groups were shown to have very high requirements for nutrition management and beauty standards. In the skin patterns, the groups of middle-aged women, house wife and the lower income showed high interests, with a high significance (P<0.01) in ages. With respect to body shape, significant interest was found within the groups of skin type (P<0.05) and age (P<0.001). With regard to supplementary foods, all groups showed a strong intention to purchase, but no significant differences were found. This study indicates the necessity to categorize supplementary foods by the intended target group, such as women planning to conceive, pregnant women, and lactating women.

This study develops pant patterns using body shape, measurement and shell mesh data to decide optimal women's pants according to styles with excellent size, fit and shape for different individuals and silhouettes. Standard landmarks, lines, triangles and structures were set on a 3D scanned lower body shell to represent women in their twenties and flattened as a 2D pattern. Patterns were created and analyzed according to culotte, formal, slacks and tight type considering crotch shape, location of the crotch point, and adjusting waist darts. Flattened patterns were rotated to compare existing methods. The crease lines were then set through the hip protrusion point and compared. The main factor of the pant pattern were extracted, total rise, crotch depth, crotch width, angle of center line, shape of the center line curve, the thigh width, the amount of waist dart, and crease line position. With going tight style from the culotte, the fits are closer to the figure with minimized thigh circumference, the dart amount decreases, the crotch depth increases, the crotch extensions were shorter, and the angle of the center back increased. The total rise is U shape for culotte and is closer to V shape as the silhouette tightens. T-test of appearance evaluation of the developed pant pattern were conducted after analyzing measurements and shapes of each styles. The results of the developed patterns were superior to existing patterns in accordance to hip line between body and pants as well as appearance evaluation. We found systematic mechanisms among pattern factors that create various pant silhouettes. Evidence on classification of the silhouettes of traditional types of pants were explained objectively through the process of playing out 3D forms.

This study improves maternity clothes worn by pregnant women across each trimester. A total of 164 survey results from pregnant women living in the metropolitan area around Seoul, South Korea were received from November 2015 to July 2017. The results of this study were as follows. First, Internet shopping purchases were significantly lower during the first trimester of pregnancy than during the mid-trimester and third trimester (p<.001). Further, satisfaction levels with most items purchased online were significantly lower in the first trimester of pregnancy. Regarding the purchase price, there was no difference according to the pregnancy trimester. During the first trimester of pregnancy less body shape changes occur than in the mid-trimester and third trimester; however, the first trimester shows the lowest satisfaction levels for each item of maternity clothing and most body parts when worn. There were also no differences according to pregnancy trimester in terms of preferred maternity clothes purchased, but there were significant differences according to occupational status. Working pregnant women generally preferred not to reveal their body shape.
