This research deals with a scheduling problem that minimizes makespan in a single setup-operator and non-identical parallel machine system, in which the machine dependent setup time of each job is divided into internal and external setup times. The internal setup refers to those setup actions that inevitably require that the machine be stopped, and the external setup refers to actions that can be taken while the machine is operating. We first present a mixed integer linear programming formulation for the problem, and using this formulation, the optimal solutions for relatively small problems can be easily found. However, since the problem is NP-hard and the size of a real problem can be large, we propose a genetic algorithm based heuristic to solve the practical big-size problems in a reasonable computational time. To assess the performance of the algorithm, we conduct a computational experiment, from which we found the heuristic algorithm shows very good performances.

Recently, the proportion and importance of senior start-up with experience and infrastructure have been increasing, and various start-up support policies have been tried. The purpose of this study is to propose the importance and priorities of the factors influencing seniors' entrepreneurial intention using AHP analysis. To this end, 99 students from start-up schools in capital area were surveyed, and valid responses of 38 students verified both reliability and CR were analyzed. In addition, a comparison was made by a group according to age and start-up experience.
The results of this study are as follows; First, importance ranking that affects the intention of start-up was in the order of entrepreneurship, start-up support, and social recognition. Second, in terms of age group comparison, start-up support was the most important factor under 50 years old, but over 50 years old, entrepreneurship was the most important. Third, start-up support was chosen to be the most important factor by the group with no experience in start-up, while entrepreneurship was the most important in the group with experience in start-up

In this paper, a research model was designed to investigate the factors influencing the satisfaction and continued use intention of B2C Cross Border e-commerce in China. Our research model includes the system quality factors (accessibility, security, convenience), information quality factors (informativeness), service quality factors (responsiveness, empathy), satisfaction and continued use intention based on IS success model.
A survey was conducted to collect the data with users who have had the actual using experience about B2C Cross Border E-commerce platform. In this research, the data were collected by online survey, and in final analysis, 368 users' questionnaires were used. The empirical paper proves research hypothesis by using SPSS 25.0 and AMOS 23.0. The result of the study are as follows: the information system quality factors partially give positive effects to perceived satisfaction and logistics service quality factors also partially give positive effects to perceived satisfaction. In addition, satisfaction has positive effect to continued use intention.

Social commerce as a new transaction platform offers attractive opportunities to market participants. However, the emerging opportunities also require comprehensive understanding of consumer's decision-making behaviors. This study explores influencing factors on social commerce users' purchase intention. This study proposes trust, diversity, ease of use, and service quality as primary antecedents and empirically investigates how these factors affect purchase intention. Data were collected through online survey from WeChat users in China. The research hypotheses were tested using a path analysis method based on a multiple regression model by analyzing the relationships under consideration

Many companies attempt to transform themselves into creative organizations to create high performance. Organizational culture and dynamic capabilities are essential to make a creative organization. As the participation of women in society is more prevalent than ever, enterprises should have more concern on creating an environment that maximizes the capability of women as a way of improving the business performance.
The purpose of this study is to verify the mediating effect of dynamic capabilities that affects creativity for the organizational culture to influence organizational effectiveness in a rapidly changing environment, the fourth Industrial Revolution. Furthermore, this research investigates differences in organizational culture and dynamic capabilities according to gender characteristics.
The result of this research is as followings. Rational culture affected to organizational effectiveness, however, Hierarchical culture affected only to creativity as a sub-factor of organizational effectiveness. Absorptive transformation capabilities as a sub-factor of dynamic capabilities mediated organizational culture and organizational effectiveness. And absorptive transformation capabilities positively affected to the organizational effectiveness in hierarchical culture as well. Rational culture positively affected to both dynamic capabilities and organizational effectiveness regardless of gender. In the rational culture, women are more involved to their job than men, and their performance is more than twice as high. Hierarchical culture influenced men's dynamic capabilities, but did not affect women's dynamic capabilities.
Thus, this study represents that enterprises should build rational culture to business performance by utilizing the competence of female workers and have more concern on making environment for employees to exercise their dynamic capabilities.
