This study examines the relationship between the organizational member's information security mind and organizational information security level. The influential relationships among organizational members' information security mind are investigated, and the relationship between organization's information security level and information security mind has been analyzed. As a result, too manager's information security mind is shown to give the biggest influence to other group in the organization. A strong positive correlation exists between organizational member's information security mind and the level of organization's physical, technical, managerial information security. However, there is no significant difference in information security level by types of business. In the future, a more profound study on information security mind is necessary. And alternative methods of information security level estimation need to be studied.

The standard issue in the information and telecommunication industry is increasingly important with the rapid development of technology. This paper proposes an index model which can measure the degree of standardization in the Korean information and telecommunication field. We first classified ICT sector into 14 sub-sectors. Then for each sub-sector, we considered a set of important determinants to measure the level of standardization, and constructed a linear equation using this set of determinants. Finally we estimated the relative degree of importance of each determinant using the AHP methodology. The proposed model found that overall level of standardization in the Korean ICT industry is relatively low, and ‘IMT-2000 technology’ and ‘computer network technology’ among 14 sub-sectors are highly standardized sub-sectors. The validity of the proposed model was also partially proved using two different methods, holistic and historical approach.

Due to the excessive zero-sequence voltage in dual three-level inverter fed open-end winding induction motor systems, zero-sequence circumfluence which is harmful to switching devices and insulation is then formed when operating in a single DC voltage source supplying mode. Traditionally, it is the mean value instead of instantaneous value of the zero-sequence voltage that is eliminated, through adjusting the durations of the operating vectors. A new strategy is proposed for zero-sequence voltage elimination, which utilizes unified voltage modulation and a decoupled SVPWM strategy to achieve two same-sized equivalent vectors for an angle of $120^{\circ}$, generated by two inverters independently. Both simulation and experimental results have verified its efficiency in the instantaneous value elimination of zero-sequence voltage.

An active policy role is suggested for collaboration that will enhance national level Science and Technology (S&T) capabilities. In contrast, some studies see a limited role of policy support for collaborative S&T research at the individual level (including research groups or institutional levels) due to their self-organizing nature. Two views on S&T collaboration look at different levels but existing research largely ignores the context of developing countries. This paper shows how S&T collaborations between Brazil and Korea have developed over the past two decades. The paper indicates the gaps between initiation and the actual establishment of collaborative research at national and individual levels, differences in the focus areas of research, differences in resources and project planning, and the nature of collaborations. Collaborative research activities at the national level were initiated before the individual level but activated later than the individual level; in addition, the focus areas of research were laid down earlier at the national level with individual collaborations focused on different areas. Project types remained different at each level (i.e. top-down and bottom-up) or with a slightly changing mix. This study suggests appropriate policy measures (such as the timely and effective information collection of activities at different levels and proactive coordination) that could reduce the gaps in the timing and alignment of research areas. This paper also alludes to an evolutionary model to develop S&T collaboration among developing countries.

This Study intends to Investigate the economic impact of information technology investment. Six countries in OECD are selected and analyzed to understand the empirical relationship between informatization level and productivity Correlation test and regression analysis are executed, using macro data concerning informatization index, total factor productivity and real output per worker hour The impact of informatization level on productivity is characterized by the time lag effect which is used to explain the productivity paradox in precedent studies. Empirical analysis shows that the higher informatization level and information intensity, the lower time lag effect. The result indicates that IT investment has characteristic as sunk cost and the economic impact is appeared after a certain period of time.

Due to the rise of Information & Communication Technology (ICT) adoption in many fields, it is necessary to diagnose the informatization situations of corporations in agriculture and give suggestions for improvement. For this goal, surveys were designed and conducted to understand the current informatization situations of agriculture corporations in Korea. The survey covers the plan for utilizing information technology, the establishment of infrastructure for information technology, IT application status, and its effect on their performance. The specific focus of our research is to segment the corporations by their type of industries and their level of sales and give differentiated managerial implications for each segment. This is because the type of informatization and information technology assistance they need highly depends on their industry type and sales level. Based on descriptive statistics and regression analyses, tailored managerial and polic.

This study addresses information technology using level has an effect on the collaboration and organization's performance depending on the partnership that is important because of rapid development of information technology and internet diffusion. In the long view, information technology persistently increases the performance and expects the useful factor for the examing the organization's performance. Information technology using level leaves the lowness or highly, information technical application effort for the future value of each enterprise is necessary, the staff education which continuous for this the fact that the introduction is more important what continuously is information technology which is suitable at the enterprise of execution. The main purpose of this study is to figure out the difference between collaboration and organization's outcome using information technology using level that is moderating variable and difference the effect.

Public R&D investment information has diverse implications for researching R&D trends. Also, as it is important for the establishment of R&D policy to grasp the current situation and trends of R&D to improve science and technology level, science and technology information service system, such as NTIS (National Science & Technology Information Service), is operated at a national level in most countries. However, since the data forms provided by current NTIS are raw data, it is necessary to develop the R&D performance indicator or to use additional scientometric methods by analyzing scientific papers or scientific R&D project information for grasping R&D trends or analyzing R&D task results. Thus, this study applied public R&D investment information to investigate and monitor R&D trends in the field of information & communication technology (ICT) of meteorology and climatology by using NTIS data of Korea and NSF (National Science Foundation) data of USA.
