Purpose: This study aimed to develop the following scales on women's environmental health and to examine their validity and reliability: severity, susceptibility, response efficacy, self-efficacy, benefit, barrier, personal health behavior, and community health behavior scales. Methods: The item pool was generated based on related scales, a wide literature review, and indepth interviews on women's environmental health according to the revised Rogers' protection motivation theory model. Content validity was verified by three nursing professionals. Exploratory factor analysis, convergent validity, and internal consistency reliability were examined. Results: The scales included 10 items on severity, 11 on susceptibility, 10 on response efficacy, 14 on self-efficacy, 8 on benefits, 10 on barriers, 17 on personal health behavior, and 16 on community health behavior. Convergent validity with the environmental behavior scale for female adolescents was supported. The Cronbach's α values for internal consistency were good for all scales: severity, . 84; susceptibility, .92; response efficacy, .88; self-efficacy, .90; benefits, .91; barriers, .85; personal health behavior, .90; and community health behavior, .91. Conclusion: The evaluation of the psychometric properties shows that these scales are valid and reliable measures of women's environmental health awareness and behaviors. These scales may be helpful for assessing women's environmental health behaviors, thereby contributing to efforts to promote environmental health.

This study was intended to develop a new measure for environmental education research, named ‘Subjectively Responsible Environmental Behavior(SREB), in order to overcome a few of limitations embedded in the previous measures. The results of the study suggested that there were several barriers for learners to take environment-friendly actions, willingness to act was always stronger than self-reported act and the degree of discrepancy between willingness to act and self-reported act is correlated with perceived effectiveness, perceived difficulty, and expected guilty. In terms of participation, this study defined one of major missions of environmental educators is to help learners to identify and overcome such barriers. A new measure that this study has proposed can be better utilized to evaluate effectiveness of environmental education curriculum or programs and find information necessary for modifying the programs than to assess learners' achievement. Some limitations of the proposed measure were also discussed.

From the students' point of view, this study was carried out to find out barriers to environmental conservation practice of secondary school students. According to the questionare and interview with secondary school students on barriers to environmental conservation practice at home, school, society and fellow-relation conditions and in personal psychology, the following findings were resulted. The major barriers to environmental conservation practice are (1) not doing environmental conservation practice of parents, friends and neighborhood, (2) having no interest in environment and environmental problems, (3) dirty and laboriousness of environmental conservation practice, (4) lack of environmental equipments, (5) the shortage of chance and time for environmental conversation practice, (6) lack of the inducement for environmental conservaton from school, (7) little effects of individual environmental practice, (8) a busy life, (9) shortage of the voluntary courage to practice for environmental conservation, (10) lack of compensation on the environmental conservation practice, (11) anti-environmental behavior among friends, (12) urging on edcation of parents. Those barriers related with home, school, society and fellow-relation anti-environmental conditions hold back environmental conservation practice of secondary school students. Those barriers are divided into three closely correlated tipes, (1) unpleasant traits of environmental conservation practice such as cleaning, recycling were linked with personal psychology, (2) lack of the social interest and practice for environmental conservation were linked with personal psychology, (3) the social atmosphere to urge on education was linked with students' busy life and the shortage of chance and time for environmental conversation practice. According to the results, attractive environmental education programs, home environmental education, cooperative environmental conservation programs, and inducements for environmental conservation are reguired of secondary school students to promote environmental conservation practice.

This study was motivated to understand ways in which actors (students) perceived internal and external conditions of actions in determining responsibility of so-called environment friendly actions. To understand hidden reasons by which students conduct specific environmental actions more or less frequently may be more important and meaningful for environment teachers than to measure and know the frequency that their students do such actions. This study has been implemented by applying questionnaire survey to 752 ruddle school and high school students and 211 environment teachers. To test the hypothesis of this study that there would be significant differences in awareness of environment friendly actions and barriers to implementing those actions between students and environment teachers, frequency analysis and f-test have been conducted. Primary results of this study can be summarized as follows; It has been found that there were a number of evidences showing significant differences in awareness of environment friendly behavior between students and teachers. In term of action frequency, significant differences have been observed in 11 of the listed 20 actions. Similar resulted have been found in terms of perceived difficult, perceived effectiveness, and perceived guilty. These results seem to support an argument that the current list-making and checklist style of connecting students to so-called environment friendly actions need to be reviewed in a critical manner.

Structures designed for wind have an opposite design approach to those designed for earthquakes. These structures are usually reliable if they are constructed in an area where there is almost no or less severe earthquake. However, as seismic activity is unpredictable and it can occur anytime and anywhere, the seismic safety of structures designed for wind must be assessed. Moreover, the design approaches of wind and earthquake systems are opposite where wind design considers higher stiffness but earthquake designs demand a more flexible structure. For this reason, a novel Machine learning framework is proposed that is used to assess and classify the seismic safety of the structures designed for wind load. Moreover, suitable criteria is defined for the design of wind resistance structures considering seismic behavior. Furthermore, the structural behavior as a result of dynamic interaction between superstructure and substructure during seismic events is also studied. The proposed framework achieved an accuracy of more than 90% for classification and prediction as well, when applied to new structures and unknown ground motions.

The performance of full-scale steel and composite bridge safety barriers under vehicle crash is evaluated by using the nonlinear explicit finite element code LS-DYNA. Two types of vehicles used in this study are passenger car and truck, and the performance criteria considered include structural strength and deformation, occupant protection, and post-crash vehicle behavior. It can be concluded that the composite safety barrier satisfies all performance criteria of vehicle crash. Although the steel safety barrier satisfies the performance criteria of occupant protection and post-crash vehicle behavior, it fails to satisfy the performance criterion of deformation. In all performance evaluations, the composite safety barrier exhibits a superior performance in comparing with the steel safety barrier.

BACKGROUND/OBJECTIVES: Unhealthy food choices among young adults are common globally, and the incidence of chronic diseases, such as obesity, is rising. Food literacy (FL) is important for improving and maintaining individual health in a rapidly changing food environment and can form the basis for following a sustainable diet. Therefore, it is essential to improve FL among young adults, particularly college students, who are in the formative years of their lifelong food habits. This study examined the facilitators and barriers of FL and related dietary behavior among college students in South Korea. SUBJECTS/METHODS: This study recruited 25 college students with different residence types using convenience and snowball sampling. In-person, telephone, and video interviews were conducted from March to November 2021. The interview data were analyzed using framework analysis based on the socio-ecological model. RESULTS: At the individual level, prior good experiences with food were the most frequently mentioned facilitator. In contrast, the major barriers were a lack of knowledge, financial hardship, irregular schedules, and academic stress. At the interpersonal level, the influences of family and peers, such as early exposure to healthy eating habits and opportunities to have easy accessibility to farms and farming, are major facilitators, but the lack of a sense of community was the major barrier. At the environmental level, the major barriers were unfavorable food environments at home and in neighborhoods, such as the absence of kitchens in housing and large packaging of produce at markets. CONCLUSIONS: Many factors affected the students' FL and related healthy eating practices. These findings suggest that a campus-based FL program should be developed by reflecting on these facilitators and barriers.

In the context of Sustainable development, China, the world's second-largest apparel market, is also concerned about the environmental impact of fiber waste. Currently, there is a great interest in sustainable fashion in both supply and demand in China. Based on the theory of planned behavior(TPB), the determinants of sustainable fashion consumption(SFC) of Chinese consumers were evaluated in this study: man-nature orientation(MNO) and environmental knowledge(EK) as motivation and perceived online-store accessibility(POA) and perceived money availability(PMA) as barriers. Wenjuanxing, a Chinese professional survey collection agency, conducted an online survey of millennials in Shanghai, China. The final sample size for the survey was 215. Partial least squares structural equation modeling was employed to test the proposed hypotheses. The results indicated that attitudes, subjective norms, and perceived behavioral control significantly affected the purchase intention towards sustainable fashion products. MNO and EK influenced the attitude, whereas EK, POA, and PMA influenced perceived behavioral control. This study contributes to the TPB literature through the examination of four antecedents: MNO, EK, POA, and PMA. The findings provide valuable insights for retailers and markets based on the identification of the motivations and barriers that enhance the purchasing intention of Chinese millennials toward SFC.
