Hips of the Golden and Labrador retrievers in Korea were evaluated with the University of Pennsylvania Hip Improvement Program (PennHIP) and the severity of joint laxity and degenerative joint disease (DJD) were compared to the PennHIP database. The distraction index (DI) of domestic Golden and Labrador retrievers was significantly higher than the DI of the PennHIP database. In the two breeds, the prevalence of DJD increased according to the DI. However, the severity of DJD did not show a positive correlation with the DI. Overweight dogs and dogs kept indoors showed more severe DJD and more prevalence of clinical signs. This report is thought to be the first case presentation of a large population of Golden and Labrador retrievers in Korea and the findings are representing the overall level of canine hip dysplasia (CHD) of domestic Retrievers, as the PennHIP method was not available in Korea until 2001. We can respect that the stock of retrievers can have a tighter hip joint through control of CHD using an accurate diagnostic method keyed to a phenotype especially concern for joint laxity using PennHIP method and an organized screening program. The clinical manifestation of dysplastic dog can be reduced through control of bodyweight and the environment with regular monitoring the hips with concern for joint laxity using PennHIP method.

Purpose: This study was performed to investigate the influence of the condition with and without external support on the strength of hip flexor in supine position in subjects without core stabilization. Hip flexor muscles are very functional in the hip joint structures. Therefore, it is essential to evaluate the strength of hip flexor in a clinical and precise way. Methods: Twenty subjects participated in this study. The double bent leg-lower test was used to evaluate subjects without core stabilization. The strength of hip flexor muscles was evaluated in supine position, both with and without external support condition. The paired t-test was used to compare the strength of hip flexor muscles according to external support. The level of statistical significance was at α=0.05. The intra-rater reliability of the repeated measures of hip flexor strength was estimated by calculating the intra-class correlation coefficients (ICC). Results: In subjects without core stabilization, the strength of hip flexor in supine was greater with external support than that without external support (p<0.05). In addition, the intra-rater reliability with an ICC (3, 1) of the strength measurement of hip flexor with external support was higher than that without external support. Conclusion: In subjects without core stabilization, the condition with external support can contribute to the strength of hip flexor in supine position and the strength measurement of hip flexor should be considered with the condition with and without external support.

The purpose of this study is to identify current trends in hip-hop fashion in korea and how they are influenced by musical characteristics of female hip-hop. This study considers the relationship between female hip-hop music and their fashion through the history of hip-hop. Data has been collected and analyzed from broadcastings, performances, music videos, and album jackets of female musicians who appeared in the cable television program 'Unpretty Rapstar' by MNET during two seasons in 2015. "Unpretty Rapstar" is the first program to focus on the music and fashion of female Korean hip-hop musicians. For the theoretical review, this article examines books and journal articles, which provide insight into the history and formation of hip-hop. It also analyzes the hip-hop styles of female musicians in Korea through Hiphopplaya.com, an Internet site specializing in hip-hop. the results of the analysis of the fashion of female Korean hip hop musicians is as follows: The characteristics of the styles of female hip-hop artists come out of Glam Style, which emphasizes femininity, but is also composed of a practical and dynamic street casual style. Most of the clothes are skinny jeans and sweat suits with vertical and slim-fit silhouettes or stadium jackets and jersey jackets with oversized silhouettes. The main colors of these outfits are prominently yellow and red with darker grayish tones, but also include natural achromatic colors.

This research aims to propose an ergonomic design process for hip protector based on previous studies, existing products, multidisciplinary experts opinion, and wearing test. The elderly are more likely to suffer a hip fracture when they fall due to their physical changes in skeletal form, muscle quantity, bone density, and joint movement. A hip protector is an effective product to prevent hip fractures in the elderly but it also has a problem in that it is uncomfortable. Therefore there is a high chance that it won't be able to prevent hip fractures properly. Since the comfort of a hip protector is one of the most critical elements in preventing a hip fracture, we need to keep improving the hip protector for mobility and usability. Based on the previous studies and limitations of current hip protector products, we need to come up with an optimal design for the Korean elderly. First, knowledge has to be built relating to the ergonomic design of the hip protector considering body shape and size analysis using 3D-scan data, and biomechanical analysis on hip fracture. Second, we need to develop a design process including hip protector pattern design, and wearing evaluation with virtual system. Third, we suggest to reevaluate and verify the design procedure from impact evaluation using testing simulator, virtual evaluation of impact, to wearing comfort and usability evaluation. This design process presented in this study would be expected to contribute to the development of ergonomic hip protector which is suitable for the Korean elderly.

Background: Delivery workers repeatedly get in and out of trucks and walk or run to deliver packages during work. Iliotibial band syndrome (ITBS) is a well-known non-traumatic overuse injury of the lateral side of the knee caused by frequent knee flexion and extension. Hip muscle strength is among the factors that prevent lower extremity injuries. Although many studies have examined the relationship between ITBS and hip muscle strengths, there was no study comparing hip muscle strength and ratio between delivery workers with and without ITBS. Objects: This study aimed to compare hip muscle strength and hip internal/external rotator and adductor/abductor strength ratios between delivery workers with and without ITBS. Methods: Fourteen delivery workers with ITBS matched inclusion criteria in the present study among 20 participants. Because total sample size was required 28 subjects by G*power program (ver. 3.1.9.4; University of Trier), 14 delivery workers without ITBS were recruited. Hip muscle strengths were measured in a side-lying position using a Smart KEMA pulling sensor (KOREATECH Co. Ltd.). An independent t-test was used to compare hip muscle strengths and hip internal/external rotator and hip adductor/abductor strength ratios between delivery workers with and without ITBS. Results: The adductor/abductor strength ratio was significantly greater in delivery workers without ITBS than in those with ITBS (p < 0.05). The strengths of the hip abductor, hip adductor, hip internal rotator, hip external rotator, and the ratio of internal/external rotator strengths were not significantly different between the delivery workers with and without ITBS (p > 0.05). Conclusion: This study's findings showed that delivery workers with ITBS had significantly lesser adductor/abductor strength ratio, while the strengths of the hip abductor and adductor muscles did not differ significantly. These results suggest that adductor/abductor strength ratio should be considered when evaluating and treating ITBS in delivery workers.

Traumatic hip joint dislocations account for 2-5% of total joint dislocations. Bilateral asymmetric hip joint dislocation with anteriorly and posteriorly dislocation is an even more rare case because it was according to G. Loupasis reported in 11 cases only since 1879. We want to report 2 cases of bilateral asymmetric hip joint dislocation with unilateral acatabulum fracture which happened in our hospital. Bilateral asymmetric dislocation of hip joint accompanied by unilateral fracture of acetabulum is a very rare case so statistical verification cannot be done. However, close examinations are required at early treatment and follow-up because the patterns of dislocation and fracture of hip joint are variable and an orthopedic emergent condition and several complications may occur at both hip joints.

The hip-hop fashion of the nineteens is just as important in hip-hop as in rapping, breaking, or graffitiwriting to young people. Hip-hop fashions major influences range from martial-arts moves, to street-gang uniforms and paraphernalia. Hip-hop fashion grew and evolved with the subculture. The identification with street-gang culture is important to hip-hop in general and still set the pace for hip-hop fashion. There are things that are necessary fashion components for each segment of hip-hop life. So even prisons are now selling prison clothes. Explaining the look, The rawest street element is a jail element, so the strongest statement is a uniform with shirts and trousers that match perfectly, like a jail piece. Insiders can detect the away of gang and prison culture on the iconography of seemingly innocuous brands. Hip-hop glam is part of an evolution of hip-hop style. Rap's gone luxe, and it is women who are leading the high-fashion charge. They wear in diamonds and fur. Now it is a very glam. Now, many brands are upping their marketing activities through a focus on their women's lines in advertising, and featuring hot celebrities. There is also a lot of rethinking of looks going on. Sexy and tight is emerging as the style of choice in this market and fabrications are becoming more important, as designers refine and upgrade their women's line. The clothes of hip-hop glam were the ordinary with the extraordinary: Designer fur and leather with athletic team jerseys, Nike sneakers, diamond bracelets and mall brands like Guess and Fubu. The hip-hop musician's sporty hip-hop looks has amply young people. The hip-hop looks of baggy jeans, oversized shirts and rugged outerwear have become a part of mainstream fashion. Hip-hop fashion has the characteristics of being sporty. In the 90s, Military look has got one of the fashionable hip-hop fashion style. It does not have inner symbolic meaning or ideology but it only represents a fashion trend and revival fashion. Not only fashion designer but also hip-hop musician selected the trend for hip-hop fashion style.

The purpose of this study was to classify Y generation according to Hip Hop mania elements and to investigate the differences in psychological characteristics (self-consciousness, egocentrism) and buying behavior of Hip Hop fashion among the classified groups. The subjects were 500 middle and high school students living in Seoul and Kyonggi area.46g data were analysed using cluster analysis, ANOVA and Duncan's multiple range test. The results were as (follows : As a result of classifying Y generation with Hip Hop mania element including behavior and attitude aspect they were classified into three groups; Hip Hop mania group, Hip Hop interesting group, Hip Hop uninterested group. Among groups there were significant differences in public and private self-consciousness, self-centeredness, evaluative criteria of Hip Hop fashion, information sources and clothing store patronage. Hip Hop Mania group showed significantly higher level in both public and private self-consciousness, thus the members of the group were so egocentric in their thinking and behavior. When they purchased Hip Hop fashion, they regarded both aesthetic appreciation and practicality as import information.

Active straight-leg raise (ASLR) is a physical evaluation procedure to test lumbar spine stability. Several previous studies have reported various methods to control the activation of abdominal muscles during ASLR. We investigated the effects of three different hip positions in frontal plane on abdominal muscles to increase or decrease the difficulty level of lumbar spine stability exercise during ASLR in pain free subjects. Eleven young and healthy subjects voluntarily participated in this study (6 men, 5 women; mean age=$24.0{\pm}1.2$ years, height=$160.0{\pm}7.3cm$, weight=$55.0{\pm}10.6kg$, body mass index=$21.5{\pm}2.3kg/m^2$). The subjects had three trials on each ASLR with hip $10^{\circ}$ adduction, neutral hip, and hip $30^{\circ}$ abduction. Separate repeated-measures analysis of variance (ANOVA) and the post hoc Bonferroni tests (with ${\alpha}$=.05/3=.017) were performed for each muscle among the three different hip positions in frontal plane (ASLR with hip $10^{\circ}$ adduction, neutral hip, and hip $30^{\circ}$ abduction). The ipsilateral external oblique (EO), contralateral EO, ipsilateral internal oblique/transverse abdominis (IO/TrA), and contralateral IO/TrA were significantly greater in ASLR with hip $30^{\circ}$ abduction compared with ASLR with hip $10^{\circ}$ adduction. Also, the ipsilateral EO, contralateral EO, and ipsilateral IO/TrA were significantly greater in ASLR with hip $30^{\circ}$ abduction compared with ASLR with neutral hip. These results suggest that ASLR with hip $30^{\circ}$ abduction and neutral would be useful method to strengthen the EO and IO/TrA. And, ASLR with hip $10^{\circ}$ adduction would be effective in early stages of lumbar stabilization program due to low activation of EO and IO/TrA during maintaining of ASLR position with low load.

Variations of individual hip shapes are a major obstacle in pattern making for fitness. The drafting method is used for pattern making in today's apparel industry. Whilst catering to a limited number of information such as waist and hip sizes, this method does not cater to variations in hip shape. This paper describes the analysis of hip shapes using 3D body model and tries to make sure the relationship between hip shape and pattern by calculating hip angle and dart amount. We achieved results in analyzing various hip shapes by extracting hip angle. Moreover, various hip shapes can be divided into three types(A, B and C) by the hip angle value($K_{sh}-K_{wsh}$). When we use computerized draping method to make a personalized pattern for a tigth skirt, we easily create complex dart lines automatically. Therefore we achieve the result of individual dart amount such as distance between dart lines and dart areas. C type of hip shape had short dart length, long distance between dart lines and a large amount of dart area. On the other hand, A type had long dart length, short distance between dart lines and small amount of dart area. B type had long length and long distance between dart lines and large amount of dart area. In traditional pattern making, distance between dart lines is usually proportional to amount of dart area because of similarity in dart line shape. In our pattern, there is no proportional relationship between dart line distance and dart area. This means that variations in hip shapes result in a wide variety of dart line curvature resulting in a wide range of dart area. By ensuring an accurate relationship between hip shape and pattern, it is possible to make patterns which result in clothing that not only fits well, but also exhibits other desirable properties.
