This study is toidentify what makes people uncomfortable when people wear new shoes and to gain fundamental data for establishing shoe sizes. Data materal from the 16 measurement investigation conducted on 796 college girl students shows the following. 1) More than 96% of the subjects have experienced footache when they wore new shoes. It is significant that 45.76% of the subjects answered shoe width, especially pump-lining part cause them to feel more pain in their feet than any other measurement elements. 2) According to multiple correlation analysis to know which parts of feet determine shoe size, both multiple correlation coefficient of feet length to other parts of foot and joint girth to other parts of foot show the highest of R=0.93. 3) According to the ANOVA-tested result of estimated function when both foot-length-joint girth and foot length-joint girth-foot width are independent variables in each case, the level of α〈0.001 is very significant. 4) The comparision between KS G3116 adult women's shoe size establishment table and my table in this study reveals that the cases of more increased joint girth measurements than standard joint girth measurements in KS G 3116 table are easy to find.

For children with most outdoor activities, wearing appropriate shoes is important to their growth and health. The purpose of this study is to identify characteristics regarding children's feet and to provide beneficial information for an appropriate sizing system of children's shoes. The data of the study were 3D measurements of feet from school boys aged 7-12 of the 6th Anthropometry of Size Korea. This study revealed that the two factors related to the size and height of the feet represent the characteristics of children's feet, unlike adults. As a result of applying the data of this study to the current KS sizing system of the children's shoes, only the foot lengths were within the sizing system. Consequently, the current sizing system requires revisions and supplements to the foot-width and foot-circumference sections.

The foot shape from the right and left feet was taken with 78 male and 213 female Korean subjects. The results are as follows. 1) Mean values and standard deviations of 25items concering the foot : Measurements performed on Korean adults(male and female) show that male left foot length is in average somewhat longer than the corresponding right foot length(25.35Cm against 25.32Cm) and on the contrary that the circumference of the left foot is slightly smaller than for the right foot. For the same tendency is verified in female feet. 2) Correlations between measurement items : Finding a correlation of more than 0.08 only between the foot length to suggest that the present system of ready-made "shoe" size system, based only on foot length, is not a quite appropriate system. 3) Distribution between foot width, foot girth, instep height and foot length : Foot length showed from 21.52Cm to 24.0Cm in the female subjects and from 24.0Cm to 26.5Cm in the male subjects for the standard type. Foot width showed from 7.5Cm to 10.0Cm in female and from 8.5Cm to 10.5Cm in male for the standard type.dard type.

Purpose: The purpose of this study is to find out the correlation factors for prognosis of calcaneal fractures. Materials and Methods: 120 cases (feet) of calcaneal fractures, all of them followed up for more than 1 year after surgical procedures, consisted of 101 men (105 feet) and 13 women (15 feet) were reviewed retrospectively. The collected clinical data were as follows : injury mechanism, surgical procedures, time to procedure, time to work and the radiologic data: Bohler angle, heel width, displacement of posterior facet. AOFAS hindfoot score and VAS score were checked. With ANOVA test and multiple regression analysis, the data processed statistically. Results: According Sanders classification, type II was 37 cases (31%), type III 66 cases (55%), and type IV 17 cases (14%). On plane radiography, the Bohler angle improved to average 28.4 degree from 5.6 degree, and the displacement of posterior facet was corrected to average 1.2 mm. AOFAS hindfoot score was checked average 81.7 points postoperatively, and the meaningful difference existed between types of Sanders classification. The Bohler angle represented the outline of the calcaneus had the better correlation with the clinical outcome of calcaneal fractures rather than the anatomical reduction of the posterior facet did. And the width of calcaneus had good correlation with the clinical score. Conclusion: We should also concern about the outline of calcaneus, the width of calcaneus and the Bohler angle representing anatomical reduction, not only the acute reduction of the posterior facet.

Objective: This study aimed to assess the genetic parameters and accuracy of genomic predictions for twenty-four linear body conformation traits and overall conformation scores in Korean Holstein dairy cows. Methods: A dataset of 2,206 Korean Holsteins was collected, and genotyping was performed using the Illumina Bovine 50K single nucleotide polymorphism (SNP) chip. The traits investigated included body traits (stature, height at front end, chest width, body depth, angularity, body condition score, and locomotion), rump traits (rump angle, rump width, and loin strength), feet and leg traits (rear leg set, rear leg rear view, foot angle, heel depth, and bone quality), udder traits (udder depth, udder texture, udder support, fore udder attachment, front teat placement, front teat length, rear udder height, rear udder width, and rear teat placement), and overall conformation score. Accuracy of genomic predictions was assessed using the single-trait animal model genomic best linear unbiased prediction method implemented in the ASReml-SA v4.2 software. Results: Heritability estimates ranged from 0.10 to 0.50 for body traits, 0.21 to 0.35 for rump traits, 0.13 to 0.29 for feet and leg traits, and 0.05 to 0.46 for udder traits. Rump traits exhibited the highest average heritability (0.29), while feet and leg traits had the lowest estimates (0.21). Accuracy of genomic predictions varied among the twenty-four linear body conformation traits, ranging from 0.26 to 0.49. The heritability and prediction accuracy of genomic estimated breeding value (GEBV) for the overall conformation score were 0.45 and 0.46, respectively. The GEBVs for body conformation traits in Korean Holstein cows had low accuracy, falling below the 50% threshold. Conclusion: The limited response to selection for body conformation traits in Korean Holsteins may be attributed to both the low heritability of these traits and the lower accuracy estimates for GEBVs. Further research is needed to enhance the accuracy of GEBVs and improve the selection response for these traits.

The purpose of this study was to present basic data for development of shoe last suitable for women of plus size (BMI 25 kg/㎡ or higher) by type and to analyze the characteristics of each type of foot type. The results of the study are as follows. A comparison of the feet of a plus-size woman and a normal-weight woman showed that the feet of a plussize woman were thicker and wider in the toes, cheeks and feet than those of a normal-weight woman, while the ankle area was thicker. As a result of the cluster analysis by type of foot type of plus-size woman, type 1 was classified into four types, type 1 was 49 (19.5%), type 2 was 43 (17.1%), type 3 was 53 (21.1%), and type 4 was distributed among 106 (42.2%). Type 1 appeared to be a long, low heel, thick foot and wide H-type, and Type 2 appeared to be a D-type with a low heel and a thinner and narrow foot compared to other types, but with wide outer width of the foot. Type 3 showed short feet, low heels, narrow feet, but slanted sides, and Type 4 showed type A with long feet, high heels, thick and wide feet or a combination of toes.

This study sought to reveal the architectural characteristics of Quonset church built in the Archdiocese of Gwangju, and the conclusions are as follows. The Quonset structure, which was used as a military barracks during World War II and was designed to be easily assembled and disassembled quickly, was used in Damyang, Hwasun, and Gokseong churchs. They were all built in 1958, after the Korean War, and can be related to the historical background of the rapid increase in the number of Catholics. They are utility buildings that can accommodate many believers, that is, large quonsets measuring 40 feet (width) x 100 feet (length). The floor plan was largely divided into two spaces, with about 3/4 reserved for the nave and altar, and the remaining 1/4, or 24 to 30 feet, used as a sacristy or confessional. The cross-section is a semicircle with a radius of 20 feet, framed by 6-inch ribs, and its unique structure, in which bricks are stacked on the outside to form the exterior, makes it different from a typical brick church. Unlike other stone churches built around the same time, Quonset church was not expanded. This may be due to the difficulty in supplying special materials such as the ribs that make up the frame, as well as the absence of relevant experts.

This study was attempted to clarify the characteristics of elderly women's foot shape by examining the various measurements of women over 60 years old as compared with those of women in twenties considered as reference group. The subjects were 321 elderly women and 181 young women. Their right feet were measured directly and indirectly by using scanner and digital camera. The anthropometric measurements were composed of 62 items. They were measured during the months of July and August in 2001. As a result of comparing actual measurements of foot between the two groups, it was found that the elderly women tended to have shorter and lower foot than those among the young women. Among the elderly women, in addition, it was revealed that many deformities related to toes or legs led to the toes concentrated to the central axis of feet resulting in relatively steeper lateral angle of toe, and the heels and legs slanting forwards. As a result of comparing index values of foot between the groups, the elderly women's foot had the relatively wide width and low height in comparison with the length, showing more elliptical flattening than those of the young women. And, the width of the inside was wider than that of the outside, and the toe width was relatively short in comparison with the foot width resulting in severe deformities on the toes or the central axis of foot. Therefore, it was found that there were several deformities including flat foot or deformed toes among elderly women. It is expected that the characteristics of elderly women's foot shown in the results mentioned above will be used as the basic data in designing the footwear for elderly women.

This study identifies the foot shapes of elderly men by classifying foot types according to the shapes of sole of foot and analyzing individual characteristics. The subjects were 269 elderly men over 60 years of age. Their right feet were measured indirectly with a 2D scanner. The anthropometric measuring items consisted of 38 items that were estimated on the right foot of each subject. The 2D scan data were analyzed by various statistical methods such as factor analysis, ANOVA and cluster analysis using the statistical program SPSS 19.0. A total of 8 factors were extracted through a factor analysis and these factors represent 77.83% of total variance. The 8 factors were: ball and lateral foot protrusion, ball gradient, medial foot protrusion, anterior and posterior foot length ratio, lateral ball length, heel size, toes breadth, and foot length, that explained 77.83% of the total variance. A total of 4 clusters (as their sole type) were categorized using 8 factor scores by cluster analysis. Type 1 was classified as H-type(toes width, foot width, heel width uniform and medial malleolus and lateral malleolus almost no protrusion). Type 2 was classified as V-type(foot width and toes width, wide and heel width narrow). Type 3 was classified as A-type(foot width and heel width, wide but toes width narrow, protruded inside). Type 4 was classified as D-type(protruded outside).
