In several industries, including the agriculture industry, information and communication technology (ICT) expenditure has been gradually increasing. This study explores the ICT investment of Korean agricultural corporations, and examines the effect of ICT investment on their profitability using an IT portfolio framework. As the organizational capabilities and environment in which ICT is used is critical in examining its impact, the IT-savvy level is used as a moderator. An increase in ICT investment size results in a significantly positive effect on profitability in organizations with higher IT-savvy levels, whereas there is no effect in organizations with lower IT-savvy levels. This study shows the necessity of understanding the structure of ICT investments in the agriculture industry, and suggests the importance of organizational capabilities and environment in making best use of ICT.

This study, as a study on building platforms for smart campus ecosystem, took an approach that reflected the needs of various stakeholders of smart campus, and focused on functions to help them strengthen their competitiveness and advance into society by focusing on the learning of the most important university student users, college life, and social connection. First, we looked at the theories related to smart campus construction through prior research, and next, through domestic and international environmental analysis and trend analysis, we designed and presented a target model for e-portfolio focusing on core competency development and support system for Industry-Academic Cooperation, and proposed the main point for continuous smart campus development model.

현재 국제해사기구(IMO)를 중심으로 선박의 안전, 보안 및 해양환경 보호를 위해 선박 및 육상을 통합하는 전자항법 체계인 e-Navigation이 추진되고 있다. 특히 유럽의 여러 국가들이 IMO의 추진 진행 과정을 따라 실제로 e-Navigation을 해상에 구현하기 위한 여러 프로젝트들을 진행하고 있으며 그 결과들이 일부 보고되고 있다. 본 논문에서는 IMO에서 진행 중인 e-Navigation의 현황을 살펴보고 VTS 관점에서 향후 e-Navigation으로 인해 변화할 기능 또는 서비스들에 대해 검토하였다.

One of the major issues in the field of corporate training and formal education is the support of personalized learning. Successful personalized learning needs the availability of the relevant learning contents at just-in-time for learners each. The competency is one of personal characteristics. So competency-based learning is one of the methods that fulfill the above need. Successful competency-based learning needs the method that recommends the relevant contents for the user's deficient competency based on the user's current competency and objectives. We assume that there exists a student information system that provides each user's competences and objectives as fields of a LIP/ePortfolio-compliant student information. This paper proposes an ontology-based system that, given the user's competences and objectives from the above student informaton system, recommends the relevant contents among a large number of educational contents using competency ontology and domain ontology. The advantage of this system can easily handle the change of competency map and terms related with competences in student information and education contents.

As MSI(Maritime Safety Information), navigational, meteorological warnings and forecasts, was included as one of service in the MSP(Maritime Service Portfolio), which is lists of shore based service in the e-Navigation driven by IMO for safety navigation and marine protection, and was tested in the european test bed project on e-Navigation, it's considered as one of important e-Navigation service. This paper developed a prototype of MSI service to prepare e-navigation era, which is very important in a navigation environment. Current status on MSI and NAVTEX was surveyed, and several points on limitations and improvements in the NAVTEX operations were summarized. Basic study on the MSI service prototype was developed based on S-100, which is recognized as baseline to develop CMDS(Common Maritime Data Structure) of e-Navigation.

Dynamic development of the Information Communications and Technology is changing countries around the world to establish the e-government to enhance their national administrative system efficiently. This paper proposes the method to implement the e-government efficiently in the developing countries. To reach the goal, the e-government development indices evaluated by United Nations are analyzed to catch the clues to take-off the e-government development stage. In addition, we scrutinize the e-Government Master Plans of Mongolia, Kyrgyzstan and Nepal supported by Korea in order to elicit the priority projects which are the indispensible components on the way of building e-government. We cross-check and standardize the projects which the investigation target countries define respectively. We also analyze the projects which are evaluated by their priorities in compliance with the portfolio method to elicit the road map of the optimum which is able to implement the e-government efficiently with reducing trials and errors.

This study discusses some theoretical implications for efficient utilization of the global E-commerce in a world of uncertainty by beginning with measures of risk and return for the global E-commerce, and by moving to risk and return for a efficient transaction portfolio of many risky methods of transaction. Decision rules are developed to show how individuals choose optimal transaction portfolios that maximize their expected utility of wealth. First, the individuals will generally want to allocate positive amount to the global E-commerce, which requires that the expected marginal utility of wealth equals zero. Secondly, the optimal transaction portfolio will be determined by finding the point of tangency between the efficient trading line and the hightest indifference curve in the mean-variance plane. Thirdly, if the global E-commerce is positively correlated with wealth, it must have an expected return that is higher than the risk-free transaction methods in order to compensate for its risk. Fourthly, on the other hand, if the global E-commerce is negatively correlated with wealth, it will have an expected return that is less than the risk-free transaction methods. Finally, the valuation of global E-commerce depends on the degree of individual's risk aversion and the covariance between the expected return of total wealth and the return of global E-commerce.

Purpose: This study used ESG grade, but defined AESG, adjusted to the size of a company and examines whether it can be used as an investment strategy. Research design, data and methodology: The analysis sample in this study is a company that has given an ESG rating among companies listed on the Korea Stock Exchange. We examine the results through portfolio analysis and Fama-macbeth regression analysis. Results: As result of examining the long-only performance and the long-short performance by constructing quintile portfolios, it was observed that a significant positive return was shown. It was observed that there was an alpha that could not be explained in asset pricing models. Also, AESG had a return prediction effect in the result of a Fama-Macbeth regression that controlled corporate characteristic variables in individual stocks. Next, we confirmed AESG's usage through various portfolio composition. In the portfolio optimization, the Risk Efficient method was the most superior in terms of sharpe ratio and the construct multi-factor model with Value, Momentum and Low Vol showed statistically significant performance improvement. Conclusions: The results of this study suggest that it can be helpful in ESG investment to reflect the ESG rating of relatively small companies more through the scale adjustment of the ESG rating (i.e.AESG).
