This paper aims to investigate the relationship between consumption value of sports products, upward consumption propensity, and post-purchase happiness among adolescents. The subjects of the study were extracted from adolescents in Chungcheong-do by convenience sampling method, and 257 people were used in the final analysis. Statistical methods were frequency analysis, correlation analysis, and regression analysis. The research results are as follows. First, social value and exploratory value, which are sub-factors of consumption value, were shown to have a significant effect on upward consumption propensity, but functional value and self-value were found to be statistically insignificant. Second, social value, self-value, and functional value, which are sub-factors of consumption value, had a significant effect on post-purchase happiness, but exploratory value was found to be statistically insignificant. Third, the upward comparison propensity was found to have a significant effect on post-purchase happiness.

The aim of this study was to analyze contemporary sociocultural phenomena and values through characteristics of augmented reality (AR) digital fashion design. The research method included a literature review on the metaverse and augmented reality, combined with a case study using both quantitative analysis through big data text mining and qualitative analysis through constant comparison. Data analysis was conducted using Python-based open-source tools: First, 6,725 data entries were collected from AR digital fashion platforms and brands identified in articles from Vogue and Vogue Business containing keywords of 'augmented reality' and 'digital fashion. Second, text preprocessing involved stop word removal, tokenization, and POS-tagging of nouns and adjectives using the NLTK library. Third, top 50 keywords were extracted through term frequency (TF) and TF-IDF analysis, with results visualized using a word cloud. Fourth, characteristics of products' external design and internal concepts that contained top keywords were classified, with their value examined through repeated comparison. Results indicate that AR digital fashion design has the following characteristics. First, it embodies surreal fantasy through designs that mimic natural biological patterns using 3D scanning and modeling technology. Second, it presents a trans-boundary aspect by utilizing the fluidity of body and space to challenge vertical and discriminatory social structures. Third, it imagines a new future transcending traditional sociocultural concepts by expanding perceptions of space and time based on advanced technological aesthetics. Fourth, it contributes to sustainability by exploring alternatives for the fashion industry in response to climate change and ecological concerns.

This study aimed to check the role of SNS upward comparison and SNS usage motivation in the effect of contingent self-esteem on inferiority feelings by verifying the link between each variable in young adults. Depending on passed studies, a study model for the relationship of each variable was founded and the moderated mediation effect was checked. We performed a survey on 400 young adults using SNS through an online survey, and finally, a total of 351 data were employed for analysis. The outcome of the analysis was as follows. First, contingent self-esteem, SNS upward comparison, SNS usage motivation, and inferiority feelings were all affirmed to reveal a positive correlation. Second, contingent self-esteem had an important impact on inferiority feelings, which was mediated by SNS upward comparison. Third, the relationship between SNS upward comparison and inferiority feelings was moderated by SNS usage motivation. Finally, SNS usage motivation moderated the indirect effect of contingent self-esteem on inferiority feelings via SNS upward comparison. Based on the results of this study, we presented the psychological and emotional implications that can experience the inferiority feelings in young adults.

The objectives of this study are to find the competitive advantage of Bastard Halibut type. The results of analysis are as follows. First. in the profitability analysis, bastard halibut aquaculture using Herb is more profitable than other culture type. Second, bastard halibut aquaculture using Herb has more competitive power than other culture type in terms of cost, price, delivery, and flexibility. Finally, the result of comparison between culture type shows that culture technology must be concentrated on improving flesh of an adult fish. Research on the market differentiation methods in an adult fish are needed to analysis the competitive power analysis.

Objectives of this study is to investigate the behaviors of the confined concrete columns having different core sizes, lateral reinforcement ratios and spacing ratios by using the 3-dimensional analysis of confined concrete columns. In this paper, analyses are done by 3-D nonlinear finite element analysis considering continuum fracture and plasticity and then analysis results are compared with those of model tests. From the comparison, it is shown that the technique in this paper can be used effectively for the analysis of confined concrete columns.

Numerical analysis techniques have been applied to obtain the vibroacoustic characteristics of the simplified model of a passenger-car cabin. Two kinds of coupled vibration-acoustic analysis, such as one-way coupling and full coupling, have been carried out via the interface between the results of vibration analysis by FEM and acoustic analysis by BEM. The comparison of two coupled analysis results show the fluid-structure interaction in terms of the coupled effect of the vibration and noise.

Modified equivalent lumped element model for square spiral inductors have been derived. This model shows more accurate analysis performance than conventional models, and gives reliable design parameters. And this model is made through comparison among distributed multiple coupled line, numerical analysis and experimental data.

The reliability assessment of a simple porbabilistic fatigue analysis under random loading is proposed. Using the crack closure concept, the crack opening stress is assumed to be constant during random loading. The available loading history and test data are used for the comparison with the results of the reliability assessment of probabilistic fatigue analysis.
