There are three aims of this research. One is to verify the mutual effects between internal collaboration and external collaboration, another is to prove performance improvement among different levels of supply chain collaboration, and the third is to analyze gaps between the two viewpoints. The population is Korean FDI firms in China and 208 data are used in the analysis. The data are treated with various methods: exploratory and confirmatory factor analyses, SEM, cluster analysis, ANOVA, MANOVA and post hoc analysis. The results are as follows. First, external collaboration and internal collaboration have positive effects on each other, which have a positive effect on performance. This means that efficiency of internal processes is the cause of promoting connection with external processes and information generated from the market is the basis of a variance of internal processes, followed by high performance. Second, service performance improvement is more definite than cost performance improvement among different levels of supply chain collaboration. Firms can achieve more definite results in service performance when they perform supply chain collaboration. Third, this research verifies both the viewpoint of directions of supply chain collaboration and the strategic choice viewpoint of supply chain collaboration to better understand supply chain collaboration. Both viewpoints approach supply chain collaboration from different viewpoints but they do explain the methods for performance improvement.

This research has three objectives: one is to develop measuring criteria for ascertaining performance of customs clearance firms, another is to test reliability and validity of the factors, and the third is to analyze the relationship between customer service and firm performance. This research gathered the data from customs clearance firms. Reliability and validity concerned with the collected data are tested by exploratory factor analysis and confirmatory factor analysis and the relationship between variables is tested by analyzing structural equation modeling. The results are as follows. There are no problems in reliability and validity. According to the result of the analysis, customer service is divided into customer focus, customer needs, customer response and flexibility and performance is classified into customer performance and financial performance. The result of empirical tests is as follows. Customer focus has a positive effect on customer performance and financial performance. Flexibility has a positive effect on both types of performance. This means that firms which have discriminative services and a high level of flexibility through collaboration with customers can achieve high levels of customer performance and financial performance.

There are two aims of this research: one is to prove the interactive effect of supply chain integration (SCI) on performance and the other is to ascertain gaps in performance among levels of SCI. The population of this research is international freight forwarders and the collected data is used in testing hypotheses through various analytical methods such as factor analysis, Cronbach’s alpha, cluster analysis, ANOVA, MANOVA, ANCOVA, post hoc analysis and regression analysis. First, the interaction between internal integration and external integration improves customer performance and financial performance. The forwarders improve internal processes following information acquired from customers and the information is shared with logistics service providers, followed by high performance. Second, gaps in performance among levels of SCI are verified. Managers of the forwarders make strategic decision making on the basis of their recognition of environment and, as a result, the forwarders enjoy different performance.

There are two objectives of this study: to analyze gaps in customer satisfaction and to test the customer loyalty gap on the basis of the reputation of Busan New Port. This study identifies the relationships between variables as well as the conceptual and operational definitions using prior research. Data was collected from 93 members of the International Freight Forwarders Association. The reliability and validity of the data was analyzed and the relationships between the variables were tested by analysis of covariance. The results are as follows: First, the reputation of Busan New Port means the abilities in which the port provides valuable benefits to international freight forwarders. The analytical results show that there is a gap in customer satisfaction between high- level and low- level reputation. Second, the levels of reputation are based on the gap in customer loyalty. This means that there are gaps in the friendly attitude of international freight forwarders and sustainable usage on the basis of the varying levels of port reputation.

This study aims to analyze information on vessel traffic between the two Koreas with a probability distribution for each route/vessel type. The study will then conduct an estimate for maritime transport patterns of inter-Korean trade in the future. To analyze the flow of inter-Korean coastal shipping, this study conducted visualization analysis of shipping status between North and South Korea by year, ship type, and port using navigation data of three years from Port Logistics Information System (Port-MIS) sources during 2006 to 2008, which saw the most active exchanges between the two governments. Also, this study analyzes shipping status between the two governments as a probability distribution for each port and provides the prospects for future maritime transport for inter-Korean trade by means of Bayesian Networks and simulation. The results of the analysis are as follows: i) when North-South routes are reopened, the import volume for sand from North Korea will be increased; ii) investment in the modernization of ports in North Korea is required so that shipping companies can generate profit through economies of scale; iii) the number of the operating vessels including container ships between the two governments is expected to increase like when the tensions and conflict on the Korean Peninsula was release, especially between Busan port in South Korea and Nampo port in North Korea; and iv) among container ships, transshipment containers imported and exported through Busan Port will be shipped to North Korea by feeder transportation.

The purpose of this qualitative study is to explore how highly educated women respond to career chance events in a Korean context where traditional cultural values and male-dominated organizational culture coexist.

The authors conducted 50 semi-structured interviews with highly educated women operationalized as women with doctoral degrees in and out of Korea. The authors used a collaborative research process with a team of ten Korean-born researchers who have built consensus on research themes through discussions on the collection and analysis of a large data set, thus reducing the researcher bias issue inherent in qualitative research.

In an analysis of the interview data collected, the authors report on three themes: before obtaining a doctoral degree, during and after their doctoral study and responses (coping strategies) to chance events in their careers. Highly educated women’s pursuing a doctoral degree was a way to maintain work–life balance in Korea where women are expected to take a primary caregiver role. After obtaining a doctoral degree, participants struggled with limited job opportunities in the male-dominated higher education. Women’s unplanned and unexpected chance events are intertwined with the male-dominated culture in Korea, and career interruptions as such a chance event, whether voluntary or involuntary, happened largely due to family reasons. In this context, highly educated women responded to chance events largely at individual and family levels and articulated the need for support at organizational and government levels.

The study findings confirm the literature that women’s careers are limited by traditional family roles in non-Western countries where strong patriarchal culture is prevalent. Particularly, women’s career interruptions surfaced as a critical chance event that either disrupts or delays their careers largely because of family issues. Future research is called for to identify both individual and contextual factors that influence women’s decisions on voluntary and involuntary career interruptions as their responses to chance events.

Based on highly educated women’s coping strategies largely at individual and family levels, we suggest national human resource development policies put in place not to lose out on the opportunity to develop highly educated women with doctoral degrees as a quality workforce for a nation’s sustainable economic growth. Additionally, organizations need to be aligned with the government policies and programs for the provision of developmental programs for women in the workplace, beginning with highly educated women’s career planning, while creating organizational culture to promote gender equality as a long-term goal.

The participants’ voluntary career breaks helped them care for their children, be involved in their children’s education, reflect on work–life balance after having long hours of work for many years and move forward with personal satisfaction. Voluntary career breaks can be understood as highly educated women’s unique way of responding to chance events.
