Purpose: This descriptive study was to explore the factors relating to Social Physique Anxiety(SPA) in the adolescent girls(N=700). These factors included the biological(level of school[age], period of menstruation, and BMI), the sociocultural(Influence of Mass Media, [IMM], Stereotype of Ideal Female Body[SIFB], type of school, perceived figure, and ideal figure) and the BW control-related factors(experience of bodyweight [BW] control, satisfaction at the result of BW control, and motive of BW control). Method: The sample was 700 girls of the middle and high schools in Jeju-do. The data was collected by the self-reported questionnaire and processed with the SPSS Win 12.0 program. Result: 26% of the variance in SPA was explained by the biological factors(level of school) and the sociocultural factors (perceived figure, ideal figure, type of school, and IMM). SPA, IMM, and SIFB were significantly correlated with each others(r=1,65-2.92, p<.05). The mean SPA scores according to BW control-related factors were significantly different. Conclusion: This results suggest that media education is necessary to reduce or eliminate the adolescent girl's SPA. In addition, SPA needs to be considered as the important concept for the future nursing researches and interventions related to BW control.

Purpose - This study examined the effects of susceptibility to global consumer culture (SGCC) on the brand attitude of consumers of the global SPA brand in South Korea. Research Design, Data, and Methodology -Questionnaires were used, and the sample that was extracted by the convenience sampling method comprised 703 males and females, aged 20-36. The data were analyzed with SPSS 16.0 and Amos 5.0 for frequency analysis, exploratory factor analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and structural equation modeling analysis. Results - First, conformity to consumption trends was found to have a significant effect on all four variables of SPA brand attitude (brand favorability, uniqueness, ethicality, and economic utility). Second, quality perception was found to have a significant effect on brand favorability, uniqueness, ethicality, and economic utility. Third, social prestige was found to have a positive effect on uniqueness. Conclusions - The results show that consumers' susceptibility to global culture is a significant factor in their attitude to the global SPA brand. Therefore, it would be more effective if the global SPA brand develops recognition among consumers that its products play a role in sharing new trends and global lifestyles.

Recently, it has been shown that cryptographic devices such as smart cards are vulnerable to power attacks. In this paper, by mixing the randomization concept and the folding in half for secret scalar integer on ECCs, we propose an efficient and fast scalar multiplication algorithm to resist against simple power analysis(SPA) and differential power analysis(DPA) attacks. Our proposed algorithm as a countermeasure against SPA and DPA is estimated as a 33% speedup compared to the binary scalar multiplication.

This study investigates the management of clothes and the perception of up-cycling fashion based on university students majoring in fashion. Results based on 124 survey participants are as follows. First, students prioritized design when buying clothes and regarded texture as important for material. In managing clothes, male students emphasized durability; however, female participants checked fluff occurrence. Second, more than half of the respondents knew what up-cycling fashion was; overall, female students were more aware of up-cycling fashion than males. Few students purchased up-cycling clothes; however, many were willing to buy up-cycling clothes for eco-friendliness, which implies that they understood the relations between up-cycling fashion and environment. Third, pertaining to the perception of SPA fashion, students were highly satisfied with the accessibility of SPA brand stores. The group of students who knew up-cycling fashion were more satisfied with SPA brands and indicated o correlation between the cognition of up-cycling brands and preference for SPA brands. Last, in terms of the perception of environment and clothing, university students majoring fashion recognized the need for environmental protection; however, they did not emphasize environment when purchasing or managing clothes.

Sales for SPA brand names of private label apparels are on the rise in the domestic clothing market. The aim of this study is to analyze the characteristics of SPA brands and how each color system is proposed within the BI system. In this study, 8 brands were selected as the most popular SPA brands in Korea and abroad with stores based on brand power and sales and preference by consumers. Therefore, among information factors such as brand identity (BI) and color characteristic. sign system, package, and environmental factors, buildings facade and interior design of eight brands were investigated. Research into color application of BI revealed that four brands used red colors with different tones with different identity differentiation. For the other four brands, the company applied BI designs that gained the brand's character such as a black-and-white or dark blue one. Thus, it is considered important to select BI color in order to differentiate and enhance preferences in brand identity.

Due to the dramatic increase in consumers' price sensitivity and growing importance for global retailers to create relevant price strategies, this study investigates the global pricing strategy of the main SPA brands such as ZARA, H&M and UNIQLO. Based on price information shown on official website, the study developed SPA brand index by using exchange rates in terms of US dollars and ratio of differences between the local price and the US price. These figures were compared with GDP per person data in order to analyze each brand's price level against the income level. The study also compared SPA brand index with Big Mac index to identify the difference in price levels between the fast fashion market and the fast food market. ZARA and H&M were mostly targeting Middle East and Asia as a high-price market when considering index only. After taking the income level into account, however, Asia came out be the highest price market and Middle East was similar to the US market. On the other hand, UNIQLO targeted Asia as the lowest price market and the US and EU as the highest in terms of index only. But, Asia came out to be the highest price zone after considering the income level while the price of the US and EU was reasonable. Comparison with Big Mac Index indicated that most of Asia had a higher price level of the fashion market than the food market, whereas most European countries had a similar or high-price level of food market.

Simple Power Analysis(SPA) and Differential Power Analysis(DPA) attacks are Side Channel Attacks(SCA) which were introduced in 1999 by Kocher et al [2]. SPA corresponds to attacks in which an adversary directly recovers key material from the inspection of a single measurement trace (i.e. power consumption or electromagnetic radiation). DPA is a more sophisticated attacks in which the leakage corresponding to different measurement traces (i.e. different plaintexts encrypted under the same key) is combined. Defenses against SPA and DPA are difficult, since they essentially only reduce the signal the adversary is reading, PA and DPA. This paper presents a study on rekeying and sponged-based approach against SCA with current secure schemes. We also propose a fixed ISAP scheme with more secure encryption and authentication based on secure re-keying and sponge functions.

Picture Quality Improvement Systems(PQIS) have been developed for user's needs with the development of display technology. Most PQIS change the all input data, so there were some color distortion. In order to compensate such problems, the PQIS using Skin Protection Algorithm(SPA) have been proposed. But the PQIS using SPA is performed simplex color emphasis, as a result occurred color saturation and decoloration. In this paper, we proposed the modified PQIS using SPA on CIE 1976 u'v' chromaticity coordinate. The modified method operated chromaticity extension and reduction at the same time about brightness value to prevent the saturation and decoloration. We evaluated by comparing the conventional method with the proposed method of RGB Gamut variation rate using 42 test image.

A lattice-based cryptography is known as one of the post-quantum cryptographies. Ring-LWE problem is an algebraic variant of LWE, which operates over elements of polynomial rings instead of vectors. It is already known that post-quantum cryptography has side-channel analysis vulnerability. In 2016, Park et al. reported a SPA vulnerability of the public key cryptosystem, which is proposed by Roy et al., based on the ring-LWE problem. In 2015 and 2016, Reparaz et al. proposed DPA attack and countermeasures against Roy cryptosystem. In this paper, we show that the chosen ciphertext SPA attack is also possible for Lyubashevsky cryptosystem which does not use NTT. And then we propose a countermeasure against CCSPA(Chosen Ciphertext SPA) attack and we also show through experiment that our proposed countermeasure is secure.
