Purpose: The purpose of this study was to compare the factors related to violence victimization between multicultural and Korean-origin adolescents. Methods: This study used the data of the 2017 Korea Youth Risk Behavior Web-Based Survey. A total of 54,748 multicultral and Korean-origin adolescents were included in the analysis. Weighted percentage and means were used to describe the sample. Simple and multiple logistic regressions were conducted using SAS 9.2. Results: The multicultural adolescents experienced more violence victimization than Korean-origin adolescents. In both groups, middle school students, habitual drug users, and those not living with their family showed a greater risk of becoming a victim of violence. In Korean-origin adolescents, while girls and those with mid-level family economic status showed a lower risk, those who had experienced sadness or despair, suicidal ideation, smoking and problematic drinking showed a higher risk of becoming a violence victim. In multicultural adolescents, those with a lower subjective health status and a lower stress level had a higher risk of violence victimization. Conclusion: Results of this study suggest that the factors significantly related to violence victimization differ between multicultural and Korean-origin adolescents. Therefore, different approaches are required for the prevention and management of violence victimization in different populations.

Construction industry is one of the largest markets for composite materials. Composite materials are mostly utilized as surface coatings or concrete reinforcements, and they can hardly be found as a load bearing member in buildings. The three-dimensional composite structures with considerable bending, compressive and shear strengths are capable to be used as construction load bearing members. However, these composites cannot compete with other materials due to higher manufacturing costs. If the cost issue is resolved or their excellent performance is taken into consideration to overcome disadvantages related to economic-competitive challenges, these 3D composites can significantly reduce the construction time and result in lighter and safer buildings. Sandwich composite panels reinforced with 3D woven glass fabrics are amongst composites with highest bending strength. The current study investigates the possibility of utilizing these composite materials to construct ceilings and their application as slabs. One-to-one scale experimental loading of these composite panels shows a remarkable bending strength. Simulation results using ABAQUS software, also indicate that theoretical predictions of bending behavior of these panels are in good agreement with the observed experimental results.

Geogrid application that has proved to be an effective and economic method of reinforcing particles, is widely used in geotechnical engineering. The discrete element method (DEM) has been used to investigate the micro mechanics of the geogrid deformation and also the interlocking mechanism that cannot be easily studies in laboratory tests. Two types of realistically shaped geogrid models with square and triangle apertures were developed using parallel bonds in PFC3D. The calibration test simulations have demonstrated that the precisely shaped triangular geogrid model is also able to reproduce the deformation and strength characteristics of geogrids. Moreover, the square and triangular geogrid models were also used in DEM pull-out test simulations with idealized shape particle models for validation. The simulation results have been shown to provide good predictions of pullout force as a function of displacement especially for the initial 30 mm displacement. For the granular material of size 40 mm, both the experimental and DEM results demonstrate that the triangular geogrid of size 75 mm outperforms the square geogrid of size 65 mm. Besides, the simulations have given valuable insight into the interaction between particle and geogrid and also revealed similar deformation behavior of geogrids during pullout. Therefore, the DEM provides a tool which enable to model other possible prototype geogrid and investigate their performance before manufacture.

COVID-19 presented the world with a severe loss of life and impact, which has no geographical bounds or expected time to when its effects will subside. It has affected countries across the globe, disrupting economic levels and businesses in every industry while also altering individuals' everyday lives. The current research aims to examine the impact of coronavirus pandemic on entrepreneur's business activities and their perceptions on the difference in consumer behavior during this time. The findings reveal the pandemic negatively impacted business productivity and profits, forcing many businesses to physically close permanently. Surprisingly, female entrepreneurs do not perceive a change in consumer behavior compared to pre-COVID-19 times. Interestingly, the results indicate there is a negative impact on employees' efficiency to conduct work in which almost no research has conveyed such a finding. For this purpose, a survey was conducted with 445 responses from male and female entrepreneurs in the capital city of Riyadh, Saudi Arabia, using a simple random sample over the period of four months. Ultimately, this research will help entrepreneurs gain more knowledge and a deeper understanding of this new environment necessary to undertaking certain measures and adaptability in order to sustain their businesses during unprecedented times.

The role of the garment and textile industry is particularly important in the economies of many countries in the context of international goods trade. There is no denying that the garment and textile industry contributes significantly to the economic growth in the global economy. The study seeks to investigate the relationship between control variables and Vietnamese consumers' intention to buy Chinese garment products. While previous research has found some control variables influencing consumers' intention to buy products, little research has been done about the influence of control variables on consumers' intention to buy Chinese garment products, in developing countries like Vietnam. In particular, the textile industry plays an important role in export, but outsourcing is accounting for a high proportion of trade, hence, it is necessary to increase innovation to increase consumers' intention to buy domestic garment products. The data is collected from a survey of 406 Vietnamese consumers' in Hanoi city and Ho Chi Minh City. The methodology includes a mixed-method, i.e. qualitative method and quantitative method. The quantitative method applies SPSS analysis to measure the control variables' influence on Vietnamese consumers' intention to buy Chinese garment products. The results identify 1 control variable that impacts Vietnamese consumers' intention to buy Chinese garment products, which is domicile.

Purpose: A good physical appearance greatly affects a person's self-confidence, especially when the media constantly depicts that beautiful men and women are those with perfect bodies, which later forms the perception that being fat or too thin is not attractive. That is in line with the increasing knowledge and the need for nutritious foods and drinks for diets. Therefore, this study aims to see whether there is a relationship between the Weight Rejuvenation Program Everyday product innovation towards millennial purchase decision and the motivation of having an ideal body as a moderating effect. Research design, data, and methodology: Distributed online Google form questionnaires to 96 audiences who commented on "Mute" web series. The respondents consisted of 63 women and 33 men from the millennial generation who lived in Greater Jakarta and were classified as the middle to upper economic class. After all of the data were collected, they were processed using Structural Equation Modeling Partial Least Squares. Results: Product innovation had a significant influence on the purchasing decisions of the millennial consumer, but motivation did not have the moderating function in the relationships between product innovation and purchase decision. Conclusions: The main factor for product innovation that can be accepted by millennials is the product quality that remains good.

This study was undertaken to examine body image distortion among female adolescents and identify related factors. Raw data from the 14th Korean Youth Health Behavior Survey were used. The proportion of participants exhibiting body image distortion was 39.5%, with the ratio being higher among female students of normal weight as compared to underweight female students. Logistic regression revealed that the risk of having a distorted body image was higher among high school females than in middle school females having lower subjective academic performance and household economic status. In addition, the risk of having a distorted body image was higher for students who drank alcohol when compared to students who did not drink, for the group engaging vigorously in physical activity (exercise) more than three times per week as opposed to the group exercising less than three times per week, and for the group consuming less than one serving of fruit per day as compared to the group consuming more than one serving of fruit per day. Taken together, the results of this study indicate that continuous nutrition education needs to be provided so that adolescents can correctly perceive their body images and form desirable eating habits.

In recent years, many countries are committing to environmental conservation. Following this trend, successful policy implementation of SDGs with ESG management extended to the public sector is emerging as a keyword determining the success or failure of the capital market, countries, and individual companies. Accordingly, many countries are implementing various policies related to the environment. One of them is to implement national policies by introducing environmental taxes. These policies use environmental taxes to control pollution by indirectly influencing the behavior of producers or consumers through economic incentives rather than directly interfering with environmental pollution behavior. This study examines the status of environmental taxes in marine tourism sites in Korea, reviews the effectiveness of such policies, and suggests how to improve them by identifying limitations of the current system.

For Korea which has long been highly dependent on international trade for economic growth, the importance of the Brazilian market is likely to increase in the future considering its huge size of 216 million people. Therefore, it would be imperative to analyze and understand Brazilian consumer behavior correctly. This study examines differences in consumer behavior between Brazil and Korea in purchasing luxury goods. According to previous cultural studies, Brazilian consumers are expected to focus on the intrinsic value of products and show a strong compensatory consumption tendency, while Korean consumers focus on symbolic benefits and show a weak compensatory consumption tendency. After conducting and analyzing a survey of young people in their 20s in Korea and in Brazil, all of the hypotheses above were supported. The results suggests that when designing marketing communication strategy in Brazil, it will be more effective when communication is focused on the pleasure of purchasing luxury goods rather than social or symbolic benefits. This study is of greatest significance in that it is one of the few studies comparing the characteristics of Brazilian and Korean consumers.
