This research aims to examine and analyze behavior of consumers in pursuit of safety the basis of data Korea Consumer Agency in 2007 2,000 male and females older than 20 years old in Korea. In particular, this study investigates the impact of and life styles of consumers in pursuit of safety. Results of this research could be summarized as follows. First of all, Korean consumers tend to place emphasis on factors such as price and freshness rather than safety in the purchase of vegetables, meats, rice, and fruit.Second, the safety consciousness of consumers is high among female young consumers among consumers showing intermediate positions for the issue of opening domestic markets for foreign agricultural products. Third, this study also examines the impact of life styles on consumers' behavior in pursuit of safety. Such behavior is high among consumers emphasizing values on family and current consumption and showing negative attitudes opening domestic markets for imported foreign agricultural products. Finally, behavior in pursuit of safety is high among female, high school graduated, family-oriented consumers and valuing leisure and showing negative attitudes opening domestic markets for foreign agricultural products. However, safety consciousness of consumers do not generate direct impact on patterns of pursuing safety.

Coupling systems under train's collision should take the impact by absorbing the impact energy caused from the collision, so the systems are very important parts for the safety of the trains. However, it is not easy to evaluate the performance of the system because it requires a huge testing facility, which is able to control the impact and to handle many safety issues. In this paper, test results are provided, which are obtained from collision tests of a single train having a coupling system in the front, and the results are analyzed in order to understand the characteristics and the dynamic behaviors of energy absorbing materials in the coupling system, such as a hydraulic buffer, and two rubber buffers. The results show that the force of each component could be empirically described by the compression displacement and velocity. The analyzed results will be applied to simulation models, and advanced studies wouuld be available if the simulation models are well validated with the test results.

Degradation behaviors of filament-winded composites have been evaluated under the accelerated environmental test of high temperature, water immersion and thermal impact conditions. Two kinds of laminated composites coated by an urethane resin have been used: carbon-fiber reinforced epoxy(T700/Epon-826, CFRP) and glass-fiber reinforced phenolic (E-glass/phenolic, GFRP). For tensile strength of $0^{\circ}$ composites, CFRP showed little degradation while GFRP did high reduction by 25% under the influence of high temperature and water However for water-immersed $90^{\circ}$ composites tensile strength of both CFRP and GFRP showed high reduction. Bending strength and modulus of $90^{\circ}$ composites were largely reduced in water-immersion as well as high temperature environment. Urethane coating on the composite surface improved the bending properties by 20%, however hardly showed such improvement for water-immersed $90^{\circ}$ composites. In case of shear strength and modulus, both CFRP and GFRP showed high reduction by water-Immersion test but did a slight increase by high temperature and thermal impact conditions.

The purpose of this paper is to uncover whether and how contextual factors (information exchange, participation, trust in management, and training), relate to resistance to change. It also explores the mediating effect of perceived impact of change on the relations between contextual factors and resistance to change. This study is conducted in several manufacturing plants in food processing industry in Vietnam, which is implementing a top-down large-scale change - Lean transformation, adopting Total Productive Maintenance (TPM) program, to be specific. The findings suggest that all four contextual factors are negatively associated with resistance to change, in which training had the strongest impact. Also, the perceived change impact partially mediates the relationships between the four contextual factors and resistance to change. The practical implications of this paper are that employees who receive adequate, timely and useful information relating to change are less likely to show opposing behaviors towards change. Fostering trust in management among employees, and employee involvement in decision-making, also have a significant influence when addressing employee resistance to change. Employees who are well-trained, well-equipped with tools and knowledge about the change, are less likely to resist as they view the benefits of changes more significant than the risks.

In this study, the numerical simulation using AUTODYN-3D program was investigated angle trajectory prediction for inclined impacts of projectiles. The penetration and perforation of polycarbonate plate by 7.62 mm projectile was investigated numerically. The characteristic structure of the projectile's trajectory in the polycabonate plates was studied. Two combined failure criteria were used in the target plate, and the target plate was modeled with the properties of polycarbonate for simulating the ricochet phenomenon. The effect of the angle of inclination on the trajectory and kinetic energy of the projectile were studied. The dynamic deformation behaviors tests of polycabonate were compared with numerical simulation results which can be used as predictive purpose. From the simulation, the ricochet phenomenon was occurred for angles of inclination of $0^{\circ}{\leq}{\theta}{\leq}20^{\circ}$. The projectile perforated the plate for ${\theta}{\leq}30^{\circ}$, thus defining a failure envelope for numerical configuration. The numerical analyses are used to study the effect of the projectile impact velocity on the depth of penetration (DOP). It can be observed that the residual velocities were almost linear relative to penetration velocities. It means that polycarbonate has high resistance at higher velocities.

The study aims to investigate the nexus of between role identity, self-efficacy, feeling of energy, and employee creativity in the hotel industry of Korea. The employees' innovative behaviors like creativity have been many researchers' interest for decades in the hotel industry. The hypotheses depicting the relationship among the variables have been proposed based on a review of existing literature. The number of 215 cases was used for final analysis and the results were explained through structural equation modeling. The results indicate the hotel employees' role identity and creative self-efficacy positively influenced their feeling of energy. Further, both role identity and creative self-efficacy make significant impact on employee creativity. Feeling of energy also makes a positively significant impact on employee creativity. Feeling of energy partially mediates the relationship between the two independent variables and employee creativity. As a result, creative role identity, self-efficacy, and feeling of energy explain the variance of the hotel employees' creativity. The results present that hotel practitioners need to regard their employees' creative roles and build organizational culture to support creative activities so as to enhance employee creativity. Finally, theoretical and practical implications for the hotel industry and future studies have been discussed.

The influence of liquefied wood (LW) on the mechanical and thermal properties of liquefied wood-polymer composites (LWPC) was investigated in this study. The thermal behaviors of LWPC were characterized by means of thermogravimetric (TGA) and differential scanning calorimetric (DSC) analyses. LW showed significant effects on the mechanical strength properties. The increase of flexural MOE and Young's modulus was related to the increase of stiffness of LWPC. The effect of LW was also significant on the flexural and tensile MOR. The impact strength decreased with the increase of LW application level. With the increased stress concentration by the poor bonding between LW and polymer, the impact strength of LWPC decreased, compared with that of high-density polyethylene (HDPE). The thermal stability of LWPC decreased with the increase of LW content up to 40%. The melting temperature of HDPE decreased with the increase of LW loading level. Enthalpy of HDPE also decreased with the addition of LW. This study proves the thermal stability necessary for the consolidation of composition materials.

The study aims to understand the impact the consumption value changed by COVID-19 has on the purchasing behavior of industry foodservices dietitians and to provide baseline data in setting the marketing strategies for the food materials distribution companies in the future. The main survey was conducted for eight days from May 13th to 20th 2021 and 260 copies were collected and analyzed. Through the results of the study, the following conclusion elicited. First, consumption values that impact purchasing behaviors of industry foodservices dietitians are functional value and situational value. Second, for dietitians working at directly managed foodservice establishments, the higher the functional value of the food materials is, the higher the purchasing behavior. But such correlation was not found in the case of dietitians at consignment establishments. Third, compared to before and after COVID-19, the importance of functional value of food materials decreased, while the importance of situational value increased. Therefore, it is assumed that establishing marketing strategies differentiated by direct and consignment management will contribute to the energetic sales of the food material companies in the era of post COVID-19.

Consumer attitudes and behaviors towards brands are not only related to the perception of corporate brand image but also to factors such as the image of the country of origin, the characteristics of the host country, and consumer individual traits. This article focuses on Chinese multinational companies and aims to study the impact of brand international image and country-of-origin brand image on consumer behavior. A model is constructed with brand international image and country-of-origin brand image as antecedent variables, host country characteristics and consumer traits as moderators, and consumer behavior as the outcome. This study employs a questionnaire survey method targeting foreign residents living in China as participants. The research findings reveal that during the internationalization process, both brand international image and country-of-origin brand image have a significant positive impact on consumer behavior, while host country characteristics and consumer traits play a moderating role. The conclusions of this research enrich the theoretical understanding of brand internationalization and explore the influencing factors of consumer behavior, providing a basis for decision-making for multinational company executives.

This study explores the role of relationship banking for the exports of SMEs (small and medium sized enterprises) in Korea. Using a sample of SMEs listed on the Korean stock markets between 2004 and 2018, I find that relationship banking has a positive impact on exporting behaviors of SMEs. This result indicates that relationship banking is suitable for SMEs to raise their funds in the export decision-making since the incentive for banks to obtain soft information enhances SMEs' access to external finance. In particular, through further analysis considering financial constraints, I find that the positive impact of relationship banking on exports is amplified for financially constrained SMEs. In addition, the positive impact on exports is also amplified for export starters. Finally, relationship banking provides benefits for SMEs' export decision-making regardless of the financial crisis. To sum up, relationship banking may be useful means of financing for Korean SMEs whose creditworthiness cannot be assessed only by hard information. As the role of finance in international trade has recently been highlighted, this study provides insightful evidence that relationship banking may enhance exports of SMEs as a source of trade finance.
