The previous two-dimensional non-linear tidal model of the East China Sea(Choi, 1980) has been further refined to resolve the flow over the ocntinental shelf in more detail. The mesh resolution of the present finite-difference grid system used is 4 minutes latitude by 5 minutes longitude over the entire shelf. The developed fine grid two-dimensional model was utilized to reproduce the $M_2$ tide and $M_4$ tide for the East China Sea contnental shelf. There is general agreement between the model results and the current observation made in the Eastern Yellow Sea, which supports the calculated tidal regime over the shelf. Some preliminary results on maximum bottom stress and tidally-induced residual current were also examined and discussed.

This study investigates the moderation effect that organizational trust had on the relationship between perceptions of organizational politics and organizational commitment, intention to turnover, organizational citizenship behavior by analyzing the empirical data of 716 personnels collected from university hospital in Korea. We hypothesized that perceptions of organizational politics would tended to negatively related to a high level of organizational commitment and intention to turnover, organizational citizenship behaviors, and that organizational trust would moderate the relationship between perceptions of organizational politics and outcomes. These results suggest that organizational politics of perceptions had negative impacts on organizational commitment and organizational citizenship behaviors, while perceptions of organizational politics had positive impact on intention to turnover. Furthermore, the level of organizational trust moderated the relationship between perceptions of organizational politics and outcomes. Based on these findings, implications of the research findings are discussed, and recommendation for future research and practice are provided.

The purpose of this study was to empirically investigate the relationship between hospital employeesʼ perceptions of organizational politics, organizational effectiveness such as job satisfaction, organizational commitment, and turnover intention. We also evaluated the moderating effect of organizational trust on the relationships between POPs and organizational effectiveness. By analyzing 726 employeesʼ data including physicians, nurses, medical technicians, and administrators from one private hospital, POPs was found to have had a highly negative relationship with job satisfaction and organizational commitment while a highly positive relationship with turnover intention. Furthermore, organizational trust moderated the relationship between POPs and job satisfaction, and also POPs and turnover intention, while no moderating effect appeared between POPs and organizational commitment. Within the organization, employees who are in a group with high organizational trust have low job satisfaction and high turnover intention when they have high POPs rather than a group with low organizational trust. Further the implications of these results and future directions of the study have been discussed.

This paper presents a shelf life assessment for K-1 military gas masks in the Republic of Korea using test data of Chemical Materiels Stockpile Reliability Program(CSRP). For the shelf life assessment, over 2,500 samples between 2006 and 2015 were collected from field tests and analyzed to estimate a probability of proper and improper functionality using Bayesian estimation. For this, three stages were considered; a pre-processing, a processing and an assessment. In the pre-processing, major components which directly influence the shelf life of the mask were statistically analyzed and selected by applying principal component analysis from all test components. In the processing, with the major components chosen in the previous stage, both proper and improper probability of gas masks were computed by applying Bayesian estimation. In the assessment, the probability model of the mask shelf life was analyzed with respect to storage periods between 0 and 29 years resulting in between 66.1 % and 100 % performances in accuracy, sensitivity, positive predictive value, and negative predictive value.

This experimental research explores the effect of politician's voice on electors. For this experimental research, 4 groups of subjects composed of university students were exposed to different types of TV address video clips which were manipulated by tone and speed of voice, This research found that subjects exposed to low tone video clip of politician's address showed higher degree of affect and support. And those exposed to slower video clip of politician's address showed higher degree of affect but it is not connected to higher degree of support.

This study aims to examine how blockchain technology is currently being applied in various fields, as well as the methods and limitations involved in constructing blockchain, and to gauge the potential future of blockchain technology. The success or realization of the technology's applications will depend on how quickly certain technical challenges can be overcome. This paper emphasizes that with the advancement of blockchain technology, when transparency and reliability are improved, it will become a significant force in changing not only the industrial sector but also the economic and political domains. Even if the problem awareness demonstrated by blockchain technology cannot be the most effective solution for solving real-world problems, the framework it presents will provide a significant window for us to understand the problems we face in reality.

In this article, I outlined the archival management system in Early Joseon Dynasty and examined the characteristics of the system. At first, I explained the three aspects of the archival management; the memory of the past, the documentation of the contemporary, and the vision of the future through the documentation. Secondly, I tried to understand the character of the Veritable Record and its compilation by the concepts of archival science such as 'authenticity', 'reliability'. In the memory of the past, the History of a Dynasty(Koryo-Sa) and the Comprehensive History of Eastern Kingdom were included. The arrangement of the past was accompanied with the systematic study of the domestic and foreign histories. At the beginning of the state building, there was many practical need to the experiences of government and social re-construction. It was also the process of the legitimacy establishment of the new dynasty. And the Bureaucracy promoted the development of the records and archival management system because it needed the continuity and evidence of business. The dualistic structure of the records and archival management system was the most unique character of this age. The management of general administrative records was not different from the modern one. But the historical drafts and the compilation of Veritable record were different. Here, I had to examine the characteristics of these procedures by the concept authenticity, reliability, and custodianship. In doing so, I suggested the need of conceptualization of the historical terms such as 'the primary sources' and 'the secondary sources' in historical study. The archival concepts will be the most useful means to that issue. Through the memory of the past and the documentation of the contemporary, they made visions of the future, new vision of the Literati Governance. In this tradition, in spite of the revision of the Veritable records by the new changed political party, both the orignal and the revised remained as the comparative evidence for the future generation in the name of the Black-Red Revised History.

One of the advantages of SP methods is the possibility of getting a number of responses from each respondent. However, when the repeated observations from each respondent are analysed by applying the simple modeling method, a potential problem is created because of upbiased significance due to the repeated observation from each respondent. This study uses a variety of approaches to explore this issue and to test the robustness of the simple model estimates. Among several different approaches, the Jackknife method and Kocurs method were applied. The Jackknife method was implemented using a program JACKKNIFE. The model estimate results of Jackknife method and Kocurs method were compared with those of the uncorrected estimates in order to test whether there was repeated measurement problem or not and the extent to which this problem affected the model estimates. The standard errors between the uncorrected model estimates and Jackknife estimates were also compared. The results reveals that the t-ratios of Kocurs are much lower than those of the uncorrected method and Jackknife estimates, indicating that Kocurs method underestimates the significance of the coefficients. Jackknife method produced the almost same coefficients as those of the uncorrected model but the lower t-ratios. These results indicate that the coefficients of the uncorrected method are accurate but that their significance are somewhat overestimated. In this study. 1 concluded that the repeated measurement Problem did exist in our data, but that it did not affect the model estimation results significantly. It is recommended that such a test should become a standard procedure. If it turns out that the analysis based on the simple uncorrected method are influenced by the repeated measurement problem. it should be corrected.
