This study examined the effect of Internet exposure on plastic consumption behaviors, and the mediating effect of social norms. The survey participants in this study were 220 college students. Collected data were analyzed by the SPSS 26.0 and PROCESS macro 4.1 (model 4). The results of this study showed that the relationship between Internet exposure and intention to plastic consumption was mediated by descriptive norms. These results suggest that Internet exposure and social norms are important factors that can promote or constrain plastic consumption behaviors. Based on these results, we presented the theoretical and practical implications of this study.

The purposes of this study are to classify consumption values and to examine the effects of consumption values on appearance management behaviors. Questionnaires data was obtained through adults over 20 years old of age (N=478) in Gyeonggi-do, Daegu and Kyungpook regions. Descriptive statistics, factor analysis, multiple regression analysis, t-test and ANOVA were applied. The results of this study are as follows. First, consumption values are composed of three factors such as differential value, material value and practical value. Appearance management behaviors are identified such as surgery/skin care, clothing care, weight training and hair care. The weight training in appearance management behaviors is the most preferred behavior. Second, the results of regression analysis are like as follows: The effects of consumption on plastic surgery/skin care are explained by the differential value, material value and practical value(-). On weight training and hair care, the differential value and material value have positively significant effects. The differential value has significant effects on all over appearance management behaviors. Third, there are signigicant differences in consumption values and appearance management behaviors according to demographic variables. The single, females in 20s and 30s with higher monthly income and payment have higher differential value and lower practical value. The single and female in 20s and 30s were more involved in appearance management behavior.

This study aims to investigate factors influencing customer behavior towards nylon bags and single-use plastics. These factors are environmental protection awareness, health protection awareness, sense of responsibility, expectations, and green marketing. A quantitative method with the use of surveys is deployed to collect data of young people under 30, generating 1650 valid responses. The collected data is then analyzed with SPSS 22, using Cronbach's Alpha and Exploratory Factor Analysis to test the reliability of the model before validating the hypotheses by regression analysis. The study found that the majority of respondents are inclined to use plastic bags, despite their environmental awareness. The results also demonstrate that health consciousness, environmental concerns, self-driven responsibility for the sustainability of young people have a significant impact on their behaviors in using nylon bags and plastic products, whereas expectation and green marketing are confirmed not to be the factors. The study suggests that if green marketing is to gain higher influence, an increase in research and development to support other environmentally friendly packaging would be the right path. Finally, this research proposes some feasible recommendations for the government, which include imposing bolder and more targeted environmental policies on consumers and introducing educational campaigns to raise awareness about minimizing plastic consumption.

This paper is dedicated to the buckling behaviors of strengthened perforated plates under edge shear loading, which is a typical load pattern of steel plates in civil engineering, especially in plate and box girders. The square plates considered each has a centric circular hole and is simply supported on four edges in the out-of-plane direction. Three types of strengthening stiffeners named ringed stiffener (RS), flat stiffener (FSA and FSB) and strip stiffener (SSA, SSB and SSC) are mainly discussed. The finite element method (FEM) has been employed to analyse the elastic and elasto-plastic buckling behavior of unstrengthened and strengthened perforated plates. Results show that most of the strengthened perforated plates behave higher buckling strengths than the unstrengthened ones, while the enhancements in elastic buckling stress and elasto-plastic ultimate strength are closely related to stiffener types as well as plate geometric parameters including plate slenderness ratio and hole diameter to plate width ratio. The critical slenderness ratios of shear loaded strengthened perforated plates, which determine the practical buckling pattern (i.e., elastic or elasto-plastic buckling) of the plates, are also studied. Based on the contrastive analyses of strengthening efficiency considering the influence of stiffener consumption, the most efficient cutout-strengthening methods for shear loaded perforated square plates with different slenderness ratios and circular hole diameter to plate width ratios are preliminarily identified.

The purpose of this study was to investigate body image as attitude toward physical appearance, and appearance-management behavior, and to analyze the relationship between body image and life style which affects consumer behavior. The method of the study was survey research by using questionnaires. Subjects were 323 women in their twenties. Statistical analysis methods were frequency, percentage. factor analysis, discrimination analysis, one-way ANOVA, x 2- test, and Duncan's multiple range test. The results of the study were as follows. As for appearance-management behaviors of woman in her twenties. 60.1% of all respondents experienced in diet. 31.6% experienced in plastic operation, 47.4% experienced in skin care, 44.9% experienced in perfect make up, and 84.8% experienced in hair dyeing. The group with high appearance concern showed high body satisfaction. Life-style factors were analyzed into 5 factors. The group with low appearance concern considered active family-focus life factor importantly, the group with middle appearance concern considered social life factor, and the group with high appearance concern considered self-focus life type and conspicuous consumption life factor. A significant difference was found in body image between groups according to social level and demographic characteristics. The female group in the mid twenties who majors in arts and athletics, resides on southern part of Han river, and belongs to high society was analyzed to show high appearance concern and body satisfaction. and many experiences of appearance-management behaviors.

One way to achieve sustainable construction is to reduce concrete consumption by use of more sustainable and higher strength concrete. Modern building codes do not cover the use of ultra-high strength concrete (UHSC) in the design of composite structures. Against such background, this paper investigates experimentally the mechanical properties of steel fibre-reinforced UHSC and then the structural behaviors of UHSC encased steel (CES) members under both concentric and eccentric compressions as well as pure bending. The effects of steel-fibre dosage and spacing of stirrups were studied, and the applicability of Eurocode 4 design approach was checked. The test results revealed that the strength of steel stirrups could not be fully utilized to provide confinement to the UHSC. The bond strength between UHSC and steel section was improved by adding the steel fibres into the UHSC. Reducing the spacing of stirrups or increasing the dosage of steel fibres was beneficial to prevent premature spalling of the concrete cover thus mobilize the steel section strength to achieve higher compressive capacity. Closer spacing of stirrups and adding 0.5% steel fibres in UHSC enhanced the post-peak ductility of CES columns. It is concluded that the code-specified reduction factors applied to the concrete strength and moment resistance can account for the loss of load capacity due to the premature spalling of concrete cover and partial yielding of the encased steel section.

The purpose of this study is to develop home economics educational programs on the theme of 'improving consumer life' for sustainable development. It is a program to enhance the changemaker mindset for responsible production and consumption among the 17 goals of the Sustainable Development Goals(SDGs). The program was developed 8 that to make solar cookers, make household goods from recycled materials, change maker-practice green life, eco-friendly journal 1, plastic warnings, design alternatives for disposable products, change maker-efforts and eco-friendly journal 2. The developed program was validated 3 times by a group of experts and students. This program has the following features. First, the Home Economics Education(HEE) program under the theme of 'Improving consumer life' for sustainable development are carried out at the stage of change-maker education with project-based process. It can improve students' collaboration skills, self-directed skills, communication skills and problem solving skills. Second, eight programs can increase understanding and interest in sustainable development, and learners are interested in social issues. This program can raise learners who play an active role in solving social problems by increasing their interest and interest in the class, free from the form of passive classes. Third, the HEE programs under the theme of 'Improving consumer life' for sustainable development are meaningful in that they are closely related to students' lives and encourage them to practice in their own lives. Fourth, since the program is well-suited to the present time and includes content elements for sustainable development, it can induce changes in learners' perceptions, attitudes and behaviors.
