본 연구는 운임수익과 선박가격 변동을 반영한 선박투자결정모형을 검정하기 위하여 다음의 두 가지에 초점을 두고 분석을 실시하였다. 첫째, 동일한 자산의 가치를 나타내는 신조선가와 중고선가의 변동과 이로부터 발생하는 운임수익과의 관계로 정의되는 선박투자모형을 제시하였다. 둘째, 선박투자자의 행태를 분석에 포함할 수 있는 비선형 모형을 제시하고 분석대상 기간을 경제적 충격에 따른 영향으로부터 구분하여 분석을 실시하였다. 선형분석을 실시한 결과, 선박투자결정모형이 통계적으로 유의한 관계가 존재하지 않는 것으로 나타났지만, 선박에 대한 투자를 유보하는 상황이 발생할 가능성이 존재하는 투자자의 행태를 모형에 포함할 경우에 통계적 유의성이 높은 것으로 나타났다. 이는 해운시황이 급격하게 변동하는 경우 선박에 대한 투자자들의 행태가 상당히 투자유보적일 수 있음을 의미한다. In this study, we have empirically examined ship investment model regarding the relationships between ship price changes and revenues. We focus on following two issues: first, we propose ship investment model, which combines the gap between new building and secondhand ship price with revenues. Second, empirical specification that includes investor’s behaviour is extended to nonlinear framework. We divide the series based on global economic crisis and test the model to the different periods. The empirical results reveal the nonlinear cointegration test that is able to capture investor’s behaviour in shipping market shows very significant for the periods, while linear model is insignificant. This implies investor would be risk neutral when the market condition is drastically changed.

The purpose of this study is described in detail as follows. First, I would like to define what digital transformation is in the maritime transport sector. Second, it is intended to derive success factors for digital transformation in the maritime transportation field by examining various preceding studies related to digital transformation. Finally, in order to derive priorities for the derived success factors, an AHP analysis model is built and an expert survey is conducted for practical experts in the maritime transportation field. Based on the survey results, we would like to provide guidelines on what factors should be considered first among the success factors of digital transformation in the maritime transportation sector. In this study, in order to derive the priority of success factors for digital transformation in the maritime transportation field, the hierarchical structure was divided into four high-level evaluation items(strategic factors, organizational culture and human factors, technology factors, and environmental factors) and 21 sub-evaluation items. A relative evaluation method of weighting items among AHP(Analytic Hierarchy Process) was applied. AHP analysis of 24 questionnaires with a consistency ratio of 0.1 or less in order to increase the accuracy of information among questionnaires collected through maritime transportation related university professors, research groups, shipping companies, container terminals, and experts engaged in shipping related IT companies was carried out. As a result of the analysis, the priority of the first-tier factors for the success factors of digital transformation in the maritime transport sector was shown in the order of strategic factors, organizational culture and human factors, technology factors, and environmental factors. In addition, when looking at the priorities of 21 detailed items, it was found that the development of new business models, the creation of an active future digital strategy, and the leadership of the chief digital officer were high.

The purpose of the present study is to empirically examine factors that affect the information security awareness and perceived information security risk of employees of port companies. In particular, in order to identify factors that affect the perceived information security risks, we investigated the relation of assets, threats, and vulnerabilities to it, using the risk analysis methodology. With A total of 252 valid questionnaires, we also performed the structural equation modeling analysis using AMOS. It was found that first, there was no meaningful relationship between the information assets and the perceived information security risk in the case of employees of port companies. Second, threats and vulnerabilities turned out to have positive influences on the perceived information security risk. Finally, there was a positive relationship not only between the information security awareness and the information security education, but also between the information security awareness and the intention of information security. However, there was no meaningful relationship between the information security concern and the information security awareness.

Background/Aims: The aim of this study was to identify non-endoscopic predictors for the presence of large esophageal varices in Korean patients with liver cirrhosis. Methods: Among 736 patients with liver cirrhosis newly diagnosed between the year 2001 and 2005, 245 patients (171 men and 74 women, mean age of 51.9 years) fulfilled the inclusion criteria and underwent EGD as screening tests for esophageal varices. Fifteen variables were analysed to identify the presence of large esophageal varices. Results: Esophageal varices were noted in 186 patients (75.9%) and large varices in 55 patients (22.4%), while 59 patients (24.1%) had no varices at the time of initial diagnosis of cirrhosis. The causes of liver cirrhosis were viral hepatitis (41.2%), chronic alcoholism (42.4%), viral hepatitis/alcoholism (9.8%), and others (6.6%). Fifty-one percent, 35.1% and 13.9% of the patients belonged to Child-Pugh class A, B, and C, respectively. Variables associated with the presence of large esophageal varices on univariate analysis were the presence of ascites, splenomegaly (long-axis ≥12 cm by ultrasound measure), alcoholism, Child-Pugh class, platelet count, prothrombin time, and albumin. On multivariate analysis, alcohol, splenomegaly, and ascites were significantly associated with the presence of large esophageal varices. If the patients have two of them, sensitivity and negative predictive value were 80% and 91.7%, respectively. Patients without all three factors had no large esophageal varices. Conclusions: These results suggest that patients who have at least two among ascites, splenomegaly, and alcoholism would have an increased risk of having large esophageal varices.
