Corrugated board provides packaging for most diverse industries with a share of over 50%, due to the numerous advantages they offer a good protection of the products. In other hand corrugated board fails in environmental conditions, indicating that relative humidity or temperature is higher. These effects directly damage the product packaged. To overcome on this problem recently corrugated boards produced with functional material, "functional corrugated boards," have become more available in the current market. A number of commercialized forms of functional material are coated or composited products with inorganic materials, for example "Nano clay" as representative. However, although the use of functional materials is increasing in corrugated boards, the several concerns such as over cost, environmental friendly materials, recycling, and toxicity affect consumer perceptions and acceptance. In the past, number of researcher focused on process of box compression and the utility of box compression testing etc., best of our knowledge there is no review paper which focus on the functional corrugated boards used in food packaging applications. This paper aims to review the availability of functional corrugated boards in the current market, past research studies on functional material and present the current status of functional corrugated boards in leading countries.

People acknowledge that mobile technology has improved their lives in terms of convenience, flexibility, connectedness, and new freedom of choice. However, as people increase usage of technology, they may become frustrated, challenged, annoyed, and irritated with it. This is the main characteristic of mobile technology paradoxes. Once technology gets into people's daily life, which it already has, people will look for a way to minimize the dependency on the technology, as well as finding a way to use the technology to improve the quality of their life. The focus of this study is to understand the mobile technology paradoxes and to develop coping strategies. As mobile technology is already a part of people's daily life, it is inevitable that people need to utilize technology as part of their lifestyles. This study developed a research model regarding the relationship between mobile technology perception and choice of coping strategies, including personal risk propensity as a mediating factor. Discussion on the importance of the technology paradoxes for developing mobile solution and services from the customers' perspectives followed after hypotheses testing.

In thin paper, error tolerance of each array element which satisfies error tolerance of beam pattern is decided by using the Monte-Carlo method. Conventional deterministic method decides the error tolerance of each element from the acceptance pattern by testing all cases, but this method is not suitable for the analysis of large number of array elements because the computation resources increase exponentially as the number of array elements increases. To alleviate this problem, we applied new algorithm which reduces the increment of calculation time increased by the number of the array elements. We have validates the determined error tolerance region through several simulation.

Purpose: This was a methodological research to develop an instrument to assess the emotional response of family members of physically restrained patients. Methods: A primary instrument with 68 questions was developed based on literature review and semi-structured interviews with family members. A group of experts revised individual questions and removed 4 irrelevant questions. This secondary instrument, then, was tested with 199 family members of physically restrained patients in intensive care units of a university hospital. The validity and reliability of the instrument were tested by factor analysis. Results: After item analysis, 3 questions with a correlation coefficient under .30 were discarded and the questions with a factor loading under .45 on Varimax Rotation were also removed. After factor analysis on the final 37 questions, 7 factors were identified; avoidance, shock, helplessness, grudge, depression, anxiousness, and acceptance. The total variance explained was 55.63%. The reliability of this instrument was 0.93 of Cronbach's alpha. Conclusion: This instrument was statistically reliable and valid to measure family's emotional response to physical restraints of the patients. This instrument can be useful in assessing the effects of nursing interventions for family members of restrained patients.

This paper aims to investigate the effect of the factors on the e-invoice at its infant stage of adoption in the context of Vietnam. Data were collected by using a questionnaire delivered to 318 participants who are managers and accountants of companies in Vietnam from June to September 2019. The statistical methods approaches are employed to address the research issues including Cronbach's Alpha testing, Explanatory Factor Analysis (EFA), and Confirmation Factor Analysis (CFA). Then, Structural Equation Modeling (SEM) is employed to assess the proposed hypotheses model of e-invoice adoption in Vietnam. The research findings showed that direct factors have a statistically significant impact on the e-invoice adoption towards behavior, and perceived behavioral control. Perceived usefulness and perceived ease-of-use positively affect attitude towards the behavior. These factors, in turn, are impacted by perceived compatibility. Based on the research results, some practicable suggestions are proposed in order to boost the number of Vietnamese enterprises voluntarily adopting e-invoice. This study indicates the important impacts of the user's attitude and perception about control ability on intention to use. In addition, some key intuitive recommendations were proposed aiming to improve the success of the e-invoice adoption of enterprises in the context of Vietnam.

Today, high-speed trains enjoy wide acceptance as fast, convenient and environment-friendly means of transportation. However, increase in the speed of the train entails a concomitant increase in the aerodynamic noise, adversely affecting the passenger comfort. At the train speed exceeding 300 km/h, the effects of turbulent flows and vortex sheddding are greatly amplified, contributing to a significant increase in the aerodynamic noise. Drawing a biomimetic analogy from low-noise flight of owl, a method to reduce aerodynamic noise at inter-coach space of high-speed trains is investigated. The proposed method attempts to achieve the noise reduction by modifying the turbulent flow and vortex shedding characteristics at the inter-coach space. To determine the aerodynamic noise at various train speeds, wind tunnel testing and numerical CFD (Computational Fluid Dynamics) simulation for the basic inter-coach spacing model are carried out, and their results compared. The simulation and experimental results reveal that there are discrete frequency components associated with turbulent air flow at constant intervals in the frequency domain

This study evaluated the quality characteristics of rice cookies prepared with different amounts (0, 3, 6, 9%) of hibiscus powder. The pH of cookie dough decreased as the amount of hibiscus powder increased. Additionally, the moisture content and spread factor were higher in groups containing hibiscus powder than in the control groups. Furthermore, the L-value decreased with increasing hibiscus powder, while the a-value increased. The incorporation of hibiscus powder into cookies decreased hardness. Additionally, consumer acceptance testing revealed that the addition of up to 6% hibiscus powder was desirable in terms of overall acceptability. The total phenol content of the control groups was 12.32 mg GAE/100 g, while the levels in the groups containing hibiscus powder ranged from 23.32 to 59.86 mg GAE/100 g. Finally, DPPH and ABTS radical scavenging activity increased with increasing hibiscus powder level. Taken together, the results of this study indicate that amending cookies with 6% hibiscus powder can improve antioxidant activities without affecting sensory quality.
