  • The purpose of this study is to develop a reliable tool that can classify and measure detailed indicators related to the performance of ESG implementation in the country and verify their applicability. Based on World Bank's data as input data, 67 types of ESG-related detailed indicators measured in a total of 239 countries were tested to derive an optimal model that could group detailed indicators into three categories: environment, society, and governance. As a result of the analysis, it was confirmed that a total of 10 detailed indicators had a statistically significant relationship with the country's ESG performance. In addition, the detailed indicators showed a positive correlation with the primary latent variables E, S, and G, and showed a high overall index in the suitability of the model to secure the validity and reliability of variable input. As a result, this study confirmed that several detailed performance indicators constituting ESG can be classified as latent variables, and it can be said that clear criteria for the selection method and input validity of variables were presented.

  • In smart ports and port automation, the number of vertically deployed container terminals is growing. The purpose of this study is to analyze the productivity of horizontally arranged and vertically arranged container terminals by comparing the main ship operation time, and to recommend future strategies for increasing the operational efficiency of vertically configured container terminals. To achieve our goal, we chose two terminals representating each type, and collected berth allocation status data from 2018 to 2022. Then we analyzed the data using the Accelerated Failure Time (AFT) model, a parametric survival analysis technique. Under the assumption that the working circumstances of the C/C (Container Crane) are the same, we find that the productivity of on-board work of the vertically placed container terminal is higher than that of the horizontally placed container terminal. Our result also shows that the productivity is reduced during the COVID-19 period and the European ships show lower onboard work time. On the basis of these findings, we propose strategies to improve the productivity of vertical container terminals.

  • Although the port distripark concept and its development policy have been introduced since almost twenty years, there is no visible results of the policy. Specifically, the level of value-added logistics using transhipment cargo is too low. In this paper, we mainly focus on the causes of the policy failure of port distripark's value added activities in terms of conceptual as well as practical or functional. Definitely, the study reviews the concept of port distripark compared to industrial park or bonded factory. The study also analyzes the differentiation of port distripark and port hinterland. The study generats that the problem or error that may occur when port hinterland is identified with the port distripark. Last but not least, the limitations of value added logistics is generated on the study. We examined in depth whether the already well known value added activity of port distripark is really activities that add 'value'.

  • This study examined the impact of geopolitical risk on port throughput in Korea. With a high trade-to-GDP ratio, Korea has an open economy. The vast majority of its exports and imports are serviced by maritime transport. Therefore, cargo volume of Korean seaports is highly likely to be affected by changes in global economy resulting from escalation in geopolitical risk. In this regard, this study investigated the relationship between geopolitical risk and port throughput in Korea during the period of 1995-2022. Results indicated that the impact of geopolitical risk on port throughput was not statistically significant. However, the relationship varied by export, import, and ports. Especially, it was revealed that cargo volume of Korean ports was negatively associated with the level of geopolitical risk. In addition, it was also found that geopolitical risk had a negative impact on the unit price of Korean import..

  • Chinese law does not directly stipulate the criteria for determining the nationality of arbitral awards, and the Civil Procedure Law stipulates that arbitral awards are divided into domestic arbitral awards and foreign arbitral awards based on the location of the arbitration institution managing the arbitration cases. This indirectly classifies the nationality of the arbitral award based on the location of the arbitral institution. However, with regard to the nationality of eight arbitral awards in this paper made in China by the foreign arbitration institutions, the Chinese courts determined the nationality by arbitrarily selecting the criteria for the location of the arbitration institution and the criteria for the place of arbitration, except for arbitral awards made in Hong Kong. China's unclear attitude toward the criteria for determining the nationality of arbitral award has resulted not only obscures the country that can exercise the right to revoke arbitral award, but also obscures the laws and regulations applied to the approval and execution of arbitral awards. In other words, since the right to revoke the arbitral awards resides with the country of nationality of the awards, such an ambiguous attitude in China prevents the parties from responding to the cancellation lawsuit by predicting the nationality of the arbitral awards in advance. Furthermore, since China made a declaration of reciprocity reservations while joining the New York Convention, in cases where the criteria for location of the arbitral institution is applied, if the arbitration institution belongs to a contracting state, the it must apply the New York Convention to approve and execute arbitration decisions, but if it is not a contracting state, it must be approved and executed by mutual arbitration agreements or reciprocity principles. These results can lead to different results in approval and execution of the same arbitral awards depending on how the nationality is determined.

  • The pandemic of COVID-19 further promoted the imbalance in the volume of imports and exports among countries using containers, which worsened the shortage of empty containers. Since it is important to secure as many empty containers as the appropriate demand for stable and efficient port operation, measures to predict demand for empty containers using various techniques have been studied so far. However, it was based on long-term forecasts on a monthly or annual basis rather than demand forecasts that could be used directly by ports and shipping companies. In this study, a daily and weekly prediction method using an actual artificial neural network is presented. In details, the demand forecasting model has been developed using multi-layer perceptron and multiple linear regression model. In order to overcome the limitation from the lack of data, it was manipulated considering the business process between the loaded container and empty container, which the fully-loaded container is converted to the empty container. From the result of numerical experiment, it has been developed the practically applicable forecasting model, even though it could not show the perfect accuracy.

  • The Bass Diffusion Model is one of the most successful models in marketing research, and management science in general. Since its publication in 1969, it has guided marketing research on diffusion. This paper illustrates the usage of the Bass diffusion model, using mobile cellular subscription diffusion as a context. We fit the bass diffusion model to three large developed markets, South Korea, Japan, and China, and the emerging markets of Vietnam, Thailand, Kazakhstan, and Mongolia. We estimate the parameters of the bass diffusion model using the nonlinear least square method. The diffusion of mobile cellular subscriptions does follow an S-curve in every case. After acquiring m, p, and q parameters we use k-Means Cluster Analysis for grouping countries into three groups. By clustering countries, we suggest that diffusion rates and patterns are similar, where countries with emerging markets can follow in the footsteps of countries with developed markets. The purpose was to predict the timing and the magnitude of the market maturity and to determine whether the data follow the typical diffusion curve of innovations from the Bass model.

  • Chinese courts seem to be indifferent or ignorant of truncated arbitration. In other words, the Chinese court canceled the arbitration award made by truncated arbitration except for the Pingdingsan Case among the four arbitration cases related to the domestic arbitration award reviewed in this paper on the ground that it violated the composition of the arbitral tribunal or the arbitration procedure. A Chinese court has canceled the arbitration award by judging only based on the composition of the arbitral tribunal and the legal process of the violation of the arbitration procedure not by determining whether the domestic arbitration award made by the truncated arbitration meets the conditions for the application of truncated arbitration as stipulated in the Arbitration Rules. Moreover, it seems that the Chinese court made a serious error in the application of the relevant regulations in the Pingdingsan Case, which ruled that the truncated arbitration did not violate the legal process. In this case, the Chinese court admitted truncated arbitration under logic process that it was not necessary to wait until the final hearing to apply the truncated arbitraion because one arbitrator was absent before the final hearing, but the truncated arbitrator had already formed his/her opinion before the absence. However, in the case of Marshall Investment Corporation, a case related to foreign arbitration, the Chinese court rejected the approval and execution of the truncated arbitration award by strictly applying the laws and timing of the truncated arbitration. Since only one case has been identified in the main text, it is difficult to make a definitive judgment, but considering these cases, it seems to be that the Chinese courts apply different standards to domestic and foreign arbitration awards to determine the legality of truncated arbitration.

  • This paper aims at analysing the effects of venture business finance supporting programs on efficiency and productivity of the venture firms, on the basis of the data envelope analysis (DEA) using data of 406 firms in the 2013 Venture Business Detailed Survey of Small and Medium Business Administration. The conclusions are summarized as follows. First of all, the efficiency of government finance supported venture firms is higher than that other venture firms. The increase of productivity in venture firms enjoying government supporting programs is higher than that in venture business without government supporting programs, especially in the technical progress rather than in efficiency improvement. Also the R&D supporting programs for venture firms lead to an increase in productivity. Taking the above results into consideration, government's venture supporting programs are evaluated to be effective in terms of an increase of productivity and the proper scope for fragile venture firms.
