Purpose The objective of this study is to explore the influence of environmental values and consumer knowledge of green products on the attitude toward green products and the purchase intentions of green products.
Methods By studying the relevant literature, based on the VBN theory, this paper constructs the effect model and proposes assumptions. Based on 550 valid questionnaires of 568 issued survey questionnaires, by using SPSS25.0 and statistical knowledge, the reliability, validity, correlation and regression analysis of the survey questionnaire are performed to analyze.
Results According to analyze results, environmental value and consumer knowledge of green products were related to attitude and green purchase intention, environmental values partially give positive effects to attitude and green purchase intention. In addition, consumer knowledge of green products has effect to attitude and green purchase intention. consumer's attitude on the green products have a significant impact on the green purchase intention.
Conclusion The following conclusions are draw: to improve individual green purchase intention recommendations from national, businesses and consumer perspective.

Purpose This study examines the longitudinal effect of the supportive leadership style on TMX(team-member exchange). This study assume that the slope of supportive leadership style has a positively significant effect on the slope of team-member exchange.
Methods Data were extracted from a public service's Organizational Innovation Survey from 2013 to 2015 (in 3 waves), and the analysis used 70 employees that are common respondents of the 3-wave surveys. Latent growth curve model was employed to test the hypothesis.
Results The results of the research are summarized as follows. First, It was confirmed that both supportive leadership and TMX have time-dependent linearity. Second, the slope of supportive leadership had a positively significant effect on the slope of TMX(team-member exchange).
Conclusion It was confirmed that the expansion of the team leader's supportive leadership is a positive factor for the organizational performance that raises the team members' TMX, and the relationship between these two variables is a longitudinal relationship over time.

Purpose The purpose of this study is to analyze the multiple additional moderating effects of perceived usefulness of smart work and resistance to smart device in the relationship between external-oriented culture and work-family conflict.
Methods The subjects of this study were office workers who were exposed to smart work environment in the COVID-19 pandemic, and using 363 data were analyzed the multiple additive moderation effect.
Results The moderating effect of the resistance to smart device utilization and the perception of smart work usefulness in the external-oriented corporate culture promoted work-family conflict. In addition, the multiple additive moderation effect was confirmed through the conditional effect significance verification.
Conclusion Based on the results of the analysis, the present study discussed theoretical and practical implications for the balance between business culture and work-family in smart work environment.

Purpose This paper studies the revenue management problem for reusable products. A firm rents out products to customers, and the products are returned after a random duration of time. The returned products are used by other customers. Unlike the previous papers studying reusable products, this paper considers the possibility that the products are returned with breakdowns. This implies that some returned products are not used by other customers.
Methods A dynamic programming is formulated for the optimal admission control. To deal with the computational complexity of the dynamic programming, the paper develops a heuristic based on the linear programming.
Results The numerical study shows that the computational time of the dynamic programming increases significantly as the initial capacity increases. For a large initial capacity, the heuristic produces a near-optimal solution.
Conclusion Therefore, a firm with a large initial capacity is recommended to use the proposed heuristic.

Purpose This study is to demonstrate a novel risk evaluation approach using a combined weight of team experts in the Failure Mode and Effects Analysis (FMEA) model under uncertain circumstances that are caused by highly conflicting opinions between team experts and unknown information about Risk Priority Number (RPM) evidence.
Methods To recognize any uncertainty due to conflicting evidence and unknown information between the team experts, a novel combined weighting factors of the RPN evidence is generated by the framework of Dempster Shafer Theory (DST). The total combined weighting schemes is composed two parts: One part consists of belief entropy and belief conflicting coefficient to consider team experts' conflicting opinions. Whereas, another part is based on the evidence distance such as belief Euclidean distance and belief cross entropy to consider team experts' uncertainty about RPN evaluation.
Results A novel risk evaluation model using a combined weighting factors to address uncertainty in FMEA is proposed. The case study, Advanced Driver Assistance System (ADAS) consisting 7 components and 7 parts, is illustrated to show the effectiveness and usefulness of the proposed method.
Conclusions The suggested FMEA model is convenient for the risk evaluation in the following uncertain situations: i) The team experts' opinions are highly conflicting. ii) The information of RPN evidence are imprecise and unknown. The proposed FMEA method is advantageous for effectively making a group decision of team experts in the presence of uncertain RPN evidences.

Purpose This research focuses on domestic e-commerce as a tool for effective value creation strategies. The key factors used to create value are determined by lock-in, complementarity, efficiency, and novelty.
Methods This empirical research method in relation to value creation factors, customer value and purchase intention is analyzed using hierarchical regression analysis.
Results As a result of this research, the key factors used to create value in domestic e-commerce are efficiency and novelty, and customer value has a partial mediating effect on the value creation factor and purchase intention.
Conclusion This research suggests value creation factors that are important from a customer's point of view. Efficiency and novelty have a positive effect on purchase intention.

Purpose This study aims to develop a new framework for identifying and analyzing topic importance and topic satisfaction in tourism industries.
Methods After preprocessing, topic modeling is conducted. Based on the derived topics, topic importance is calculated based on the modified RFM approach. The topic satisfaction, which aims to analyze the customer experience, is calculated using sentiment analysis. Based on this, two-dimensional matrices are prepared based on the expectation level (importance) and the experience level (sentiment score).
Results Total six topics were identified from topic modeling. Topic 5, named as 'places related with plants', is considered to be a star topic, in which importance and satisfaction is high. However, topic 6, named as 'around the beach', is considered to be urgent. This means customer experience regarding topic 6 is not so high compared to what they expect.
Conclusion The framework proposed in this study is expected to enhance customer experience by systematically analyzing both customers' importance and perception for each topic.
