Loulan was an ancient kingdom located on the northeast of the Taklamakan Desert, a diverging point between the north and south of Silk Road, on the east of the current Turpan, from the 2nd century BC and the 7th century A.D, absorbing and propagating culture of both sides through active trade. Meanwhile, as many previous research investigations suggest the early trade between Korea and the countries bordering on Western China, characteristics of Loulan costume have been found to have similarity to those of ancient Korean costume. Also, it can be compared to costume in other surrounding regions. Therefore, it is a highly valuable region in researching ancient costume. This study examined the historical background of Loulan and its relationship with ancient Korea, analyzed the clothes found in historic sites of Louland and Niya, and compared costume elements of Loulan and those of Korea. The result of the study shows that first, the Loulan Jeogori was based on the Jikryeonggyoim, with Chaksu, narrow sleeves and the length coming between below the chest and above the bottom, and the line decoration and waist belt were very similar to Korean costumes, as well as the Banryeong, curved collar and Bansu, short sleeves. Second, the types of pants included Gunggo, characterized by closed bottom and many creases, and Daegugo, wide-leg trousers, which are very similar in shape to the Korean Shilla lay sculpture, Stele To Martyr Yi Ch'a-don, Yangjikgongdo and Wangheedo. Third, in accessories as well, the Jowu stuck on the Gwanmo is similar in the shapes to Korean costume.

The industry of character toys is increasing and new characters are constantly being developed. However, the development of 2D cover patterns for toys is time-consuming due to frequent pattern modifications made through trial and error. Studies are now underway to obtain 2D clothing patterns from 3D body data, however, little research has been done on 2D pattern of character toys. This study suggests efficient guidelines to develop 2D cover patterns with a reasonable accuracy and processing time. Two 3D models of a dog and rabbit were used to develop 2D cover patterns. Independent variables of this study are set as 3 levels of triangle area (small, medium, and large) that influence the efficacy of 3D and 2D pattern development. The determination of the appropriate triangular area was based on the area and shape change of the 2D pattern. A medium or large triangle area was shown to be suitable for a character dog with a smooth curved surface. However, the appropriate triangle area was small if the characteristics of the curved surface are complicated as in the case of rabbit. The head of a dog (a double-curved surface) and the curved forepaw of a rabbit (a triangular area) should be small when the characteristics of the curved surface (such as the hind leg of a rabbit having a large convex surface and a small surface area) are complicated. Grouping by 3D surface characteristics could be a suitable guideline for the triangle area selection.

In cementless total hip arthroplasty(THA), an initial stability of the femoral component is mandatory to achieve bony ingrowth and secondary long term fixation. Bone ingrowth depends strongly on relative micromotion and stress distributions at the interface. Primary stability of the femoral component can be obtained by minimizing the magnitude of relative micromotions at bone-prosthesis interface, Hence an accurate evaluation of interface behavior and stress/strain fields in the bone implant system may be relevant for better understanding of clinical situations and improving THA design. However, complete evaluation of load transfer in the bone remains difficult to assess experimentally, Hence, recently finite element method (FEM) was introduced in orthopaedic research field to fill the gap due to its unique capacity to evaluate stress in structure of complex shape, loading and material behavior. The authors developed the 3-dimensional numerical finite element model which is composed of totally 1179 elements off and 8 node blick. We also analyzed the micromotions at the bone-stem interface and mechanical behavior of existing bone prosthesis for a loading condition simulating the single leg stance. The result indicates that the values of relative motion for this well fit Multilock stem were $150{\mu}m$ in maximum, $82{\mu}m$ in minimum, and the largest relative motion developed in medial region of proximal femur with anterior-posterior direction. The proximal region of the bone was much larger in motion than the distal region and the stress pattern shows high stress concentration on the cortex near the tip of the stem. These findings indicates that the loading in the proximal femoral bone in the early postoperative situation can produce micromotions on the interface and clinically cementless TEA patient should not be allowed weight bearing strictly early in the postoperative period.

In order to evaluate the local scour around offsshore wind foundation, mono pile and jacket foundation were simulated by using FLOW-3D. Numerical analysis results show that local increases of velocity around mono pile and jacket foundation was developed but velocity decreases in backward of pile and leg due to the wake vortex was observed. Local increases of velocity around foundation and scouring of jacket is more significant than that of mono pile, since jacket is the complex structure and has the interference effect with legs. Therefore, in order to evaluate the scour and design the scour protection method, the form and shape of substructures of offshore wind should be considered.

The musculoskeletal system is mainly composed of the bones, muscles, tendons, and ligaments, in addition to nerves and blood vessels. The greatest difficulty in an ultrasonographic freeze-frame created by the examiner is recognition of the targeted structures without indicators, since an elephant's trunk may not be easily distinguished from its leg. It is not difficult to find descriptive ultrasonographic terms used for educational purposes, which help in distinguishing features of these structures either in a normal or abnormal anatomic condition. However, the terms sometimes create confusion when describing common objects, for example, in Western countries, pears have a triangular shape, but in Asia they are round. Skilled experts in musculoskeletal ultrasound have tried to express certain distinguishing features of anatomic landmarks using terms taken from everyday objects which may be reminiscent of that particular feature. This pictorial review introduces known signature patterns of distinguishing features in musculoskeletal ultrasound in a normal or abnormal condition, and may stir the beginners' interest to play a treasure-hunt game among unfamiliar images within a boundless ocean.

This is a study on the change of the Medievalmen's underclothes. Underclothing includes all such articles, worn by either sex, as were completely or mainly concealed from the spectator by the external costume. Throughout the Middle Ages, the underclothing of both sexes possessed characteristic inherited from earlier times. Its function was purely utilitarian. It was not used to express class distinction and only very indirectly to enhance sex attraction. The idea of underclothes was associated with the idea of the body's sinfulness. Underclothes could also symbolize the discipline of humility. To appear clad only in underclothes was a voluntary form of selfabasement often practised by pilgrims. The notion that underclothes might express the spirit of the changing times, in sympathy with the outer clothing, did not enter the medieval mind. The length of the shirt was less than that of the modern garment, especially after the middle of the fourteenth century. The sleeves were somewhat full, without cuffs, and cut straight. During the second half of the twelfth century, when braies become definitely an undergarment. In the fourteenth century braies became shorter and shorter and the shirt could no longer be tucked in but hung outside over the thighs. After 1340 the costume on the surface somewhat resembling modern 'tights', began to reveal display the shape of the male leg as a form of sex attraction. By the close of the Middle Ages, braies had become less like loincloths, and more like modern bathing trunks. The peasant and laborer did not attempt to keep pace with the changes of fashion but, continued, as a rule, to wear the long braies of their forefathers. The higher ranks how this garment reflected the changes of the mode of outer costumes.

The purpose of this study conducted a survey on 356 men in their twenties to investigate their recognition of their bodies. Also physical measurements were conducted on them and the lower parts of the bodies were classified into several types. The study examined the relevance of the subjects' recognition of their bodies to the physical types of the lower parts of the body. The results can be summarized as follows; There are four factors that constitute the physical shapes of the lower parts of the body and the lower parts of the body are classified into three physical types by cluster analysis. In terms of the degree of recognition of lower parts of the body shapes, the respondents' recognition of their bodies was similar to the actual measurements except for heights and leg lengths regardless of physical types, showing that they recognized well their actual physical types. With respect to the degree of satisfaction with body types, the surveyed were dissatisfied with thick circumference items and short length items. The actual measurements and the degree of recognition showed significant correlations in almost all the items while the actual measurements and the degree of satisfaction showed significant negative correlation in the circumference items. The degree of satisfaction with heights showed significant correlations with almost all measurements, demonstrating that the degree of satisfaction of the males in their twenties with the lower pats of body has closer correlations with the height items of the actual measurements that the circumference items. The degree of satisfaction with bodies was more dependent on people's recognition than the actual measurements.

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'.

In this study the swimwear pattern focused on a typical middle-aged women's body was developed and discussed. To determine the characteristics of a typical middle-aged women's body, their actual bust were cast. According to a generated flattened body surface shell, the right side of pattern was designed considering stretching ratio of swimwear materials as shown in the figure 3. Special features of the developed swimwear pattern are a bust dart, a particularly designed lining, a power-net, and a brassiere-cup. Against a commercial swimwear pattern, the darts were applied to bust area considering its volume. The lining was attached on the entire right side except brassiere part, and power-net was added twice on belly and hip part. As a result, silhouette and body shape were improved. The new brassiere-cup was designed and made to satisfy the middle-aged women's demand about their bust volume. Swimwear fitting test was performed, and it was evaluated. The developed swimwear rated activity, body support, entire silhouette, pressure, comfortable fitting, suitability with body figure, nudity higher by comparison with a commercial swimwear, as shown in the Table 6. Specially the developed swimwear satisfied future customers about a bust, a hip, a waist, a belly area, which the middle-aged women are not confident. Reducing exposure of an armhole and upper leg area, it also satisfied them. New developed swimwear pattern will provide useful reference to swimwear businesses targeting middle-aged women.

The development of prosthetic hand or prosthetic leg equipment is steadily taking place globally. Though it would be difficult to create or feel the same way as a human hand, it would be a great for the amputated person if they can pick things up or do some movement as they want. It has become possible to develop low-cost prosthetic hand according to development of 3D printing technology. If people can develop personalized prosthetic equipment at similar prices to meet this trend, the utilization and penetration rate will be much higher. In this study, it describes how to develop a user-customizable prosthetic hand using 3D printing. To do this, the transformational parameters of prosthetic hand shape modeling are extracted as variability values, and the functions for controlling prosthetic hand motion are designed as software design patterns. This allows people who need a prosthetic hand to have their own prosthetic hand at a fast and affordable price.
