This paper proposes a method that estimates credit ratings by mapping empirical probability of default (PD) and standardized historical financial ratios. Unlike standard approaches such as the parametric logit model. discriminant analysis. neural network. and survival function model. the proposed approach has an advantage of offering a multiple credit rating categories. as opposed to either default or not default. of obligors. It would provide an useful information to practitioners because the probability of default for each credit rating category is a critical input under New Basel Capital Accord. Emoirical results based upon the historical PD and financial ratios of Korean savings bank industry from 2000 and 2003 suggest that the industry’s average credit rating belong to a speculative grade. that is BB and below.

In addition, the computed transition matrix indicates that volatility of transition matrix fluctuates substantially each year and the orobability of staying in the same rating category at the end of the year tended to be much smaller than the average reported by the rating agencies for the overall Korean companies. The proposed method can easily be applied to industries other than savings bank industry.

The purpose of this paper is to analyze maritime logistics connectivity of ports and shipping networks in the East Sea Economic Rim (ESER) to promote international trade in the context of China’s Belt and Road Initiative (BRI), considering centrality, primary flow and clustering interaction.

The paper applies a complex network model, using a big data system consisting of an automated identification system, electronic data interchange and distributive and complex data. Three perspectives, including connectivity in trading ports and regions, centralities in the realm of complex network and potential marketing and regional impacts, and sixteen criteria are considered for this analysis. A visual approach has been also applied to highlight port connectivity and ship flows for the reader’s convenience.

The paper shows that port connectivity and maritime logistics are enablers to promote Korean international trade in Northeast China through the ESER, and 25 major ports are well connected to promote international trade in the region with visual data of ship flows by ship type and by flag.

Owing to the lack of port management information systems among the countries in the ESER except Korea and Japan, this paper could not capture cargo types and amounts on board. Port connectivity analysis shows links of the ports in the ESER to major ports in southeast Asia along the Twenty-first Century Maritime Silk Road (MSR). These results contribute to drawing policy implications to promote the ESER and provide suggestions for promoting Korean international trade by enhancing maritime logistics connectivity.

Unlike the existing literature showing descriptive and policy-oriented research related to ESER, this paper applied a vigorous method with a big amount of data to analyze port connectivity and ship flows in the ESER, considering China’s BRI affecting the global supply chain system, maritime transportation, and logistics. In addition, the paper shows how the seaports in the ESER are connected along the MSR.

The purpose of this paper is to identify the cause how the student movement in South Korea enjoyed the golden age in the 1970–1990s and could not be revived since the late 1990s and cannot be played a pivotal role again.

This study adopts historical analysis as primary methodology, traced the historical evolution of South Korean student activism in the 1970–1990s through analyzing secondary Korean literature and newspaper on the particular struggle cases in the period.

Social solidarity between society and student had played a pivotal role in the South Korean students' long activism in the struggle of the 1970–1990s. In the 1970–1980s, democratic election and constitutional reform set in the main purpose of struggle that attracted wide support from society and enjoyed maintaining a new member supply and their commitment despite authoritarian government's persistent oppression. When the sixth constitution was passed in 1987 with Democratization, the student decided to choose continuing struggle and set social cooperation with North Korea as the new goal, the sensitive issue in South Korea that confronted fierce criticism. Society chose to withdraw their support to the activism in the Yonsei University incident of 1996, rung a knell of long struggle since the 1970s.

The research identified the cause how South Korean students in university could persist long strike without particular internal resource production during three decades and ended the long struggle in the late 1990s; the existence of social solidarity between student and society was the main reason of continued new member supply and their commitment in the battle.

This study aims to elucidate the reaction mechanism of electroless NiP deposits on conductive but non-catalytic Cu films on the basis of their nucleation and growth without Pd catalyst and to measure the deposition rate and activation energy of electroless NiP deposits on the non-catalytic Cu film at various deposition times (60, 120, 240 and 480 s) and temperatures (70, 80 and 90°C) at pH 4.6.

Specimens with and without Pd catalyst on Cu film were prepared as follows: the Pd catalyst was deposited on half of the Cu film using a deposition protector, and the specimen containing the Pd catalyst deposited on half of its area was immersed in electroless NiP solution. The growth of NiP on the Cu films with and without the Pd catalyst was observed.

The number of Pd nanoparticles increased with Pd activation time; the nucleation of Pd dominated over growth at 60 s. Lattice images show that the d-spacing of Ni nanoparticles doped with less than 10 at% P increased to 2.050 Å. Nucleation of NiP deposits occurred simultaneously in the specimens with and without the Pd catalyst, because electrons could be transferred via the conductive Cu. Therefore, the reaction mechanism of the electroless NiP deposited on Cu film appears to be electrochemical. The activation energies for NiP deposits (15 s Pd with catalytic Pd, 15 s Pd without catalytic Pd, 60 s Pd with catalytic Pd and 60 s Pd without catalytic Pd) on the Cu film are 65.8, 64.0, 64.3 and 58.1 kJ/mol, respectively. This demonstrates that, regardless of the volume and the presence of catalytic Pd, the activation energy of electroless NiP has a consistent value.

It is necessary to study the relationship between the volume of Pd nanoparticles and the nucleation rate of NiP at an initial stage, as there are limited data regarding the effect of Pd volume on the nucleation rate of NiP.

The reaction mechanism of the electroless NiP deposited on conductive but non-catalytic Cu film involves electrochemical reactions because the nucleation of NiP deposits occurs on conductive Cu film regardless of the presence of the Pd catalyst.

While the origin of Korean Industrial Relations goes back 150 years when the country opened its seaports to foreign countries, it didn’t emerge as a field of study until 1950s when academics began to write books and papers on the Korean labor movement, labor laws, and labor economics. In this paper, we sketch this history and describe important events and people that contributed to the development of industrial relations in Korea. Korean industrial relations in the early 20th century were significantly distorted by the 35-year-Japanese colonial rule (1910–1945). After regaining its independence, the U.S. backed, growth-oriented, military-based, authoritarian Korean government followed suit and consistently suppressed organized labor until 1987. Finally, the 1987 Great Labor Offensive allowed the labor movement to flourish in a democratized society. Three groups were especially influential in the field of industrial relations in the early 1960s: labor activists, religious leaders, and university faculty. Since then, numerous scholars have published books and papers on Korean industrial relations, whose perspectives, goals, and processes are still being debated and argued. The Korean Industrial Relations Association (KIRA) was formed on March 25, 1990 and many other academic and practitioner associations have also come into being since then. The future of industrial relations as a field of study in Korea does not seem bright, however. Issues regarding organized labor are losing attention because of a steadily shrinking unionization rate, changing societal attitude toward labor unions, and the enactment of new and improved laws and regulations regarding employment relationships more broadly. Thus, we suggest that emerging issues such as contingent workers, works councils and tripartite partnership, conflict management, and human rights will be addressed by the field of industrial relations in Korea only if this field breaks with its traditional focus on union and union–management relations.

Constitutional uncertainty clouds the horizon in South Korea. Despite a strongly rebounding economy, uncertainty continues over the timing and format of the elections that will replace President Chun Doo Hwan. Student and labor protest could increase significantly if the ruling Democratic Justice Party (D]P) and the opposition New Korea Democratic Party (NKDP) fail to achieve a compromise on revising the constitution and holding elections. A substantial increase in political turmoil could lead to Chun's refusal to leave office or a military coup. It could also threaten the staging of the 1988 Olympics in Seoul, which in turn would reverse the country's current economic trend. If open elections were held, the DJP and the NKDP would have about the same chance of winning. An NKDP regime, however, would be more restrictive toward international business and trade than the current government.

The issue of the reunification of North and South Korea attracted worldwide attention in June 2000, when the historic summit meeting between the two top Korean leaders was held in North Korea. Although recently the two Koreas have stepped up their efforts toward reconciliation, international scholars and researchers in Korean studies seem to agree that Korean reunification will be slow and difficult. For this reason, they are researching possible solutions to the critical problems involved, and thus there has been an upsurge of published materials on reunification. This annotated bibliography aims to serve as a guide to these materials. Although this bibliography is selective in that it is limited to literature published in English since 1996, it has wide content coverage and includes books, journals, government publications, special reports, research papers, and Websites. Given the complicated and dynamic situation in Korea, this bibliography will be of use to those who are concerned with Korean reunification.
