2000년대 초반부터 많은 정보보호 관련자들은 정보보호 투자 대비 효과를 측정하고자 노력하였다. 그러한 노력으로 ROSI(Return On Security Investment)를 산출하는 여러 가지 방법 및 ROSI의 Return인 사이버 피해액을 계산하는 Gordon & Loeb 방법 등이 고안되었다. 하지만, 효과를 직접적으로 산출하기 힘든 정보보호의 구조적 특성, 관련 정보의 부족 및 사이버 피해액 산정 시 정성적인 요소가 포함되어 정확한 산출이 어렵다는 문제점이 존재한다. 본 연구는 현재까지의 연구 결과를 살펴보고 기존 방법들 중 가장 효율적이라고 생각되는 Gordon & Loeb 방법과 신진 방법 2가지에 대해 분석하고 개선된 방법을 설계하고자 한다.

The R&D productivity has the same meaning as that of general meaning. Its input includes budget, facility, schedule, idea and target, and its output includes patent, paper, technological innovation and revenue increase and technology accumulation influenced by these factors. The choice of R&D item which will have the large effectiveness after customization, resource input of proper level, application of efficient development schema, effective usage of development output, objective appraisal for the R&D output and extension for the future project are the main factors for which is suggested to enhance the R&D productivity. The management's expectation for R&D can be represented as the innovativeness of output and potential influence to outsiders. The speedy output, even if incremental investment more than planning happens, will eventually result in the productivity enhancement of the enterprise, and managers must not encounter the opportunity loss in return for the excessive investment control.

Korea has entered into the Post Catching-up era and the necessity of new innovation strategy in response is being raised. This study argues the necessity of new innovation strategy and discusses the issue of co-ordination between R&D and Human Resource for that as the key factor. From empirical analysis, there seems to be restricted inflow of outstanding human resources to manufacturing sectors and lowering effectiveness of major even with the improved compatibility between major and job. Especially, it is severe in the industries with high R&D investment. It can be interpreted as an incoordination of the technological innovation efforts from the aspect of R&D investment with human resource utilization from the aspect of new human resource. The analytical result and interpretation suggests that there should be more active improvement on the co-ordination between innovative manufacturers' efforts and human resource utilization, in order to keep sustainable development.

An IT system within a company play increasingly important role as a significant part of corporate assets. The IT system possesses an extraordinary ability to improve an organization's efficiency, effectiveness and productivity by providing competitive advantages and improving strategic business decision capabilities. Indeed, providing a more secure IT environment, improving employee productivity and enhancing business process and strategic decision capabilities are key areas to improve corporate performance. However, existing research on IT ROI of return on IT investments does not provide solid justification to stakeholders. In this paper, we analyze the IT investment during the past 28 years from 1982 to 2009 and present the results in two dimensions. First, we show the IT solution implementation analysis by years and industries based on 1,240 IT success cases from 8 different sources such as major Korea IT newspaper, IT magazines, and IT vendors. Then, the paper presents the relationship between IT capability through IT success cases and corporate business performance among 32 industries.

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.

In the paper, the system loss sensitivity index that implies the incremental system loss with respect to the change of bus power is derived using optimization technique. The index λ reaches $\infty$ at critical loading point and can be applied to actual power systems for following purposes. 1) Evaluation of system voltage stability 2)Optimal investment of reactive power focused on minimizing system loss and maximizing system voltage stability 3)Optimal re-location of reactive power focused on minimizing system loss and maximizing system voltage stability 4)Optimal load shedding in case of severe system contingency focused on minimizing system loss and maximizing system voltage stability. Case studies for each application have proved their effectiveness.

In recent years, there has been an argument that the academic performance of college students taught in English might be lower than those exposed in Korean under ceteris paribus environment. This paper examined the validity of this argument against the effectiveness of teaching-in-English, using student data from investment courses at a leading national university in Busan. Of a total of 165 students, 77 students took the teaching-in-Korean class (cohort A), whereas 88 students registered for the teaching-in-English class (cohort B). The findings did not support the popular argument. There was no significant difference in academic performance between student cohort A and student cohort B.

Public organizations and enterprises have repeated to invest in development or operation of their information systems. However, these investment projects have been not taken care of in the field of administration and evaluation. Since these information systems projects have unique characteristics such as technology sensitiveness, network effectiveness, embeddedness, and externality, it is not easy to manage and monitor them. Returns of investment for information systems should nonetheless need efficient monitoring and effective analysis for them. In this research, we propose a multi-dimensional management model on the basis of process in order to evaluate information systems.

These information systems projects have unique characteristics such as technology sensitiveness, network effectiveness, embeddedness, and externality, these investment projects have been not taken care of in the field of administration and evaluation. Furthermore, it is not easy to evaluate the results of projects under the circumstances where the conditions for evaluation of budget, time, and data leave much to be desired. But the efficient monitoring and effective analysis of information systems are surely needed for beneficient results of investment in information systems. We propose an effect evaluation model on the basis of restriction to evaluate information systems.

Lots of investment projects of new development and redevelopment for information systems have been not taken care of in the field of administration and evaluation, for these information systems projects have unique characteristics such as technology sensitiveness, network effectiveness, embeddedness, and externality. In fact, quantitative and qualitative evaluation of investments in information systems projects are not sufficient. It is critically important to generally evaluate benefits of development or operation cost, urgency, external effects, and so on. In addition, the efficient monitoring and effective analysis of information systems are surely needed for beneficient results of investment in information systems. We propose an economics evaluation model for information systems projects.
