This study investigates the effects of appearance-relative behaviors of adolescent female consumers on their awareness of heath harmfulness and skinny jeans purchasing behaviors and identifies the influential variables on the wearing satisfaction of skinny jeans. A survey was carried out with middle and high school female students and 386 responses were analyzed using descriptive analysis, factor analysis, a reliability test, and regression analysis. The results of this study were as follows, 1) From the results of the factor analysis on appearance-related behaviors and clothing benefits of skinny jeans for female adolescents, each of the variance assessments clearly showed factorial structures. 2) As a result of looking at the influences of appearance-relative behaviors on the clothing benefits of skinny jeans, respondents who paid more attention to their appearance tended to consider hygiene and activity comfort less important. In addition, respondents who had higher fashion concerns tended to consider aesthetic, practicability, desired trend, and activity comfort more important. 3) Respondents who had higher fashion concerns and considered activity comfort more important among skinny jeans benefits showed a higher level of satisfaction when wearing skinny jeans. However, respondents who thought aesthetic and health hygiene more important when buying skinny jeans showed a lower level of satisfaction when wearing skinny jeans. Female adolescents showed less satisfaction when wearing skinny jeans, as they perceived harmfulness about skinny jeans more.

This study examines wearing conditions of skinny jeans for women in their 20's. The study is based on a questionnaire survey. The survey was conducted on 313 Korean 20's women living in Gwangju to analyze wearing dissatisfaction with skinny jeans. The final analysis included 298 responses and the content of the questionnaire consisted of 28 questions. The study used descriptive statistics for analysis using SPSS Statistics 20.0. According to the questionnaire survey, 20's women are the largest group that wear skinny jeans and they have a positive image of them. However, they do not know the exact size for skinny jeans, whereas they are knowledgeable about their general pants size. The results of the survey on the state of wearing dissatisfaction indicate that they think that the difference in size by each brand is the most difficult part when choosing skinny jeans and they felt lower body uncomfortableness in the waist and abdominal positions. It means that size subdivision and pattern development of skinny jeans should be suitable to all lower body types to resolve wearing dissatisfaction. This study represents base data for size subdivision and pattern development of skinny jeans.

The recent craze for so-called skinny jeans is illustrative of the restraint of the body through dress. This phenomenon is noteworthy when considering the internalization of the corset in contemporary fashion. Grown out of the garments of soundly practical use, blue jeans have led the stream of fashion for about 150 years and now they serve as the new corset idealizing the female body in the form of skinny jeans. This study intends to examine the idealization of the body in contemporary fashion and focus on skinny jeans as an externalized corset. The struggle with corsets continues in that the real body is overwhelmed by fashion items. In the aspect of idealizing the body by constraining the body parts, skinny jeans externalize the control of the body as contemporary corsets. This study conducts literature research and content analysis as the method of investigation and focuses on women's fashion from the 20th century. Exerting a harmful influence on health (as corsets have done) the body in skinny jeans is regarded as a modifiable entity. The thinness of the body achieved by skinny jeans suggests the controlling power over the body. Moreover, this gives access to the power presented by the contemporary ideal of thinness. Skinny jeans are modern day glass slippers.

In the 2010s, skinny jeans were trendy, and they became a must-have for young women. The styles, clothing pressure and buying behavior of skinny jeans have been studied, but the patternmaking of skinny jeans has not been researched yet. To analyze skinny jeans patterns, we grouped skinny jeans into nine brands. They were sorted into three groups: special jeans brand, trendy jeans brand, and SPA brand. This study compared skinny jeans' sizing systems, product dimensions and pattern measurements in three brand groups. The appearance and fit of skinny jeans were evaluated by random groups of people in their 20s and 30s. The sizing systems for skinny jeans were different with KS K0051, and they were shown waist girth in inches. The waist and hip circumferences were different among brand groups. In product dimensions, trendy jeans brands had a shorter crotch length, a lower crotch depth, a narrower back crotch width, and a longer inseam than the others. The measurements of skinny jeans flat patterns were significantly different in as below; front crotch depth, front crotch height, front crotch length, back crotch extension, gap between back and front crotch depth, back crotch height, back crotch length, and center back angle. In the sensory survey results, trendy jeans brands were evaluated well in the fit of the waist line, hip line, crotch line, midthigh line, outseam, inseam, side waist line, crotch length and overall fit.

See-In-The-Middle (SITM) is an analysis technique that uses Side-Channel information for differential cryptanalysis. This attack collects unmasked middle-round power traces when implementing block ciphers to select plaintext pairs that satisfy the attacker's differential pattern and utilize them for differential cryptanalysis to recover the key. Romulus, one of the final candidates for the NIST Lightweight Cryptography standardization competition, is based on Tweakable block cipher Skinny-128-384+. In this paper, the SITM attack is applied to Skinny-128-384 implemented with 14-round partial masking. This attack not only increased depth by one round, but also significantly reduced the time/data complexity to 2^14.93/2^14.93. Depth refers to the round position of the block cipher that collects the power trace, and it is possible to measure the appropriate number of masking rounds required when applying the masking technique to counter this attack. Furthermore, we extend the attack to Romulus's Nonce-based AE mode Romulus-N, and Tweakey's structural features show that it can attack with less complexity than Skinny-128-384.
