The objectives of this paper are to estimate the annual Malmquist TFP(total factor productivity) index of Korea and China’s road freight transport with DEA(data envelope analysis) and to decompose the index into technical efficiency change and technology change. In the process of the estimation, we used labor, capital, and fuel as input factors and ton-km of road freight transport as output factor. The panel data of Korea and China’s road freight transport industry from 1985 to 2004 are used. The results of the analysis show several points. First, there was no significant improvement in China’s TFP growth before 1997, but there was continuous growth in TFP since 1997 because of constantly increasing domestic freight transport demand. Second, there was downward trend in Korea’s TFP, especially there was a large reduction of productivity in 1998 because of the huge reduction of road freight transport demand during the period of the economic crisis. Third, the technology improvements play a significant role in the TFP growth and the technical efficiency had negative effects on the TFP growth of Korea. However, the technology improvements as well as the technical efficiency had positive effects on the TFP growth of China’s road freight transport industry.

This paper examines how the macroeconomic environment affects the determinants of prepayment of mortgage loans from October 2004 to February 2020. For more accurate analysis, the authors define the timing of prepayment not only before the loan maturity but also at the time when 50% or more of the loan principal is repaid. The results show that, during the global financial crisis as well as the recent period of low interest rates, macroeconomic variables such as interest rate spreads and housing prices have a different effect compared to the normal situation. Also, significant explanatory variables, such as debt to income (DTI) ratio, loan amount ratio and poor credit score, have different effects depending on the macroenvironment. On the other hand, in all periods, the possibility of prepayment increases as comprehensive loan to value (CLTV) increases, and the younger the age, the shorter the loan maturity. The results suggest that, in the case of ultralong (40 years) mortgage loans recently introduced to support young people purchasing houses, the prepayment risk can be, at least partially, migrated by offsetting the increase in prepayment by young people and the decrease in prepayment due to long loan maturity. In addition, this study confirms that the accelerated time failure model compared to the logit model and COX proportional risk model has the potential to be more appropriate as a prepayment model for individual borrower analysis in terms of the explanatory power.

The purpose of this paper is to investigate key critical factors for developing transit trade corridors (TTCs) in optimizing trade and logistics performance, taking into account economic, geographic and political concerns among countries in the Northeast Asia region, which have been dynamically developing TTCs to optimize trade and logistics performance in association with development of transport infrastructure in the Greater Tumen Region located in the Northeast Asia.

This research explores key factors affecting the TTC through a comprehensive literature review in tandem with expert survey. Factor analysis, both exploratory and confirmatory, is employed to further investigate the underlying factors affecting more efficient development of a TTC.

This research has drawn eight underlying factors affecting the design of a TTC: development and policy implications; safety, security and political concerns; environmental protection; financing and investment; soft infrastructure; hard infrastructure; geography and landscape; and corridor performance.

This paper has a limited geographical scope of the Northeast Asia. Therefore, more primary data collection would be useful in future work. Development of International trade corridor and TTC is critical in northeast Asia for moving goods through designated geographical paths. The key factors drawn in this paper contributes not only to promoting its related services and information (across borders) with the provision of policy support and related facilities for TTC but also to lowering logistics costs and improving trades in the northeast Asian region. As a result, the countries in the region will accelerate their regional economies in collaboration with international bodies and framework, such as UNDP, Greater Tumen Initiative and One Belt One Road Initiative.

The eight underlying factors the authors identified in this research will be valuable for policy-makers to design TTCs and consequently the research will contribute to regional economies in northeast Asia by establishing efficient trade and transport routes among the countries in the region.

Developing TTCs is a kind of platform and infrastructure to accelerate cargo movements and people movements in the northeast Asia. Users of TTCs will benefit their businesses thanks to an efficient logistics system and lower logistics costs, which result in promoting international and regional trade in the region.

There has not been any research done on factors to consider in developing TTCs in the world, whose consequence is no readily available reference that can support a systematic assessment and decision-making in development of TTCs. The findings of this research provide a helpful reference for policy-makers, potential users and developers of TTCs to refer in planning and developing them.

The purpose of this paper is to compare the growth kinetics of interfacial intermetallic compound (IMC) layer and its effect on the tensile strength of two solder (Sn3.0Ag0.5Cu and Sn0.4Co0.7Cu) joints.

The samples annealed, respectively, at 85, 120 and 150°C up to 1,000 h were tensile tested and their cross‐sections were observed by scanning electron micrography.

The results showed that, for both solder joints, an approximately linear reduction in tensile joint strength with an increase in the IMC layers' thickness occurred. The tensile strength of Cu/Sn3.0Ag0.5Cu solder joints is slightly better than that of Cu/Sn‐0.7Co‐0.4Cu solder joints under analogous aging conditions. In addition, the growth kinetics of the overall interfacial IMC layer in Sn0.4Co0.7Cu solder joints can be simply described by the classical growth kinetic theory for solid‐state diffusion with an activation energy of 2,996.85 J/mol and interdiffusion constant of 4.15×0⁻¹⁷ m²/s which are relatively lower, compared with Sn3.0Ag0.5Cu solder on copper with 14,167.8 J/mol and 65.33×10⁻¹⁷ m²/s, respectively.

The paper is of value in evaluating the growth kinetics of Sn3.0Ag0.5Cu and Sn0.4Co0.7Cu solder joints, and in discussing and contrasting the influence of IMC growth on their tensile strength.

The purpose of this study is to understand how employees of an organization build and maintain successful business relationships by analyzing major antecedents of relationship quality and relationship commitment.

In this study, the authors develop a conceptual framework and formulate hypotheses regarding the relationships between demographic homophily, interpersonal communication, trust and dependent variables of perceived relationship quality and relationship commitment. This paper tests hypotheses presented in this study with the help of a structural equation model, based on a data sample from South Korea.

Unlike common thinking, demographic homophily does not directly increase the perceived relationship quality. The authors find a significant direct effect of interpersonal communication on relationship commitment but no effect of commitment on perceived relationship quality. Both seem to play independent roles but are positively influenced through the emergence of trust.

By applying demographic homophily and interpersonal communication as antecedents and trust as mediator and main driver, the authors research effects on perceived intra-organizational relationship commitment and perceived relationship quality. In detail, the authors confirm the hypothesized centrality of trust in intra-organizational relationships between demographic homophily, interpersonal communication and dependent variables of perceived relationship quality and relationship commitment. Nevertheless, the authors surprisingly find neither significant evidence that demographic homophily increases the perceived quality of a relationship, nor does it lead to higher communication intensity directly, even in an environment (i.e. Korea), where it would be expected.

Based on the findings of this study, there are several practical implications. Understanding the interpersonal relationship characteristics in an intra-organizational setting enables managers to optimize organizational efficiency and effectiveness. Intra-organizational relationships between employees’ are highly dependent on mutual trust as an indicator for relationship quality and relationship commitment. Organizations can also benefit from the understanding of the mechanisms of demographic homophily and interpersonal communication for the establishment of interpersonal trust as well.

Research about the effect of demographic homophily and interpersonal communication and the central role of trust in an intra-organizational approach to business relationships on perceived relationship quality and relationship commitment is scarce. The mutual testing of the effects and interaction of established constructs like demographic homophily, interpersonal communication and trust on perceived relationship quality and commitment constitutes the main contribution of this study to the literature on management and business relationships. The insights of this study about interpersonal bonding help companies to establish long-term business relationships.

This study aims to examine how employees' perceptions of organizational actions, such as corporate social responsibility (CSR), affect their compassionate acts in organizations through employee perceptions of organizational justice and affective organizational commitment.

The employees from 87 firms in South Korea were surveyed using a self-administered instrument for data collection. Out of 400 questionnaires, a total of 253 usable questionnaires were obtained after list-wise deletion, for a 63.3 percent response rate. The firms belong to a variety of industries (banking and financial services, manufacturing, hospitals, education, etc.).

The results indicate that employees' perceptions of CSR positively relate to compassion at work through organizational justice perceptions (i.e. perceptions of distributive justice, procedural justice, and interactional justice), and affective organizational commitment, in a sequential manner, in addition to their direct effects on compassion at work.

This study sheds new light on both the compassion and the CSR literature due to its attempt to bridge the macro concept of CSR with micro research in compassion. This is, apparently, one of the first pieces of research in the management literature to specifically address compassion as a consequence of employees' CSR perception.
