B2C, B2B와 같은 인터넷 상거래뿐만 아니라, 전자정부를 통한 G2C 등에서 보는 바와 같이, 공공 및 민간 IX(Internet exchange)를 통한 인터넷 상호연동 인프라는 명실상부한 사회 신경망으로 기능한다. 따라서 전통적인 사회간접자본인 도로, 항만, 전력 등에서와 마찬가지로, 그 구축 및 운영에서의 안정성과 신뢰성에 대한 요구가 점차 강화되고 있다 본 연구는 인터넷 상호연동망의 안정성과 신뢰성을 제고하기 위한 방안을 위험관리 관점에서 제안한다. 먼저, 인터넷 상호연동의 강건성(robustness)을 높이기 위한 방어기제와 더불어 상호연동 대안들을 개발한다. 이들 대안은 장애시에 작동하는 별도의 상호연동 비상망을 운영하는 방재형과, 지역적으로 분산된 상호연동 허브(IX)를 운영하여 장애에 따른 피해 확산을 방지하는 분산 허브형으로 구분된다. 본 논문에서는 또한 대안들의 위험효율성(risk efficiency)을 체계적으로 비교/평가하기 위하여 경영공학 방법론에 의한 위험평가 프레임워크를 개발하고, 이를 투자수준이 상이한 여러 대안들에 적용한다. 몬테카를로 시뮬레이션을 통한 ROI(Risk On Investment) 분석 결과, 방재형 대안이 비용 대비 위험효율성 측면에서 최선의 후보로 평가되었다.

The technological innovation of high-tech enterprises plays a positive driving role in operational performance. Investigating the factors influencing the operational performance of high-tech enterprises and the effects of technological innovation on operational performance is a targeted approach to promoting the growth of economic benefits and enhancing the foundation of enterprise efficiency. Additionally, it holds positive significance for the increase in market share of high-tech enterprises. This paper, considering the characteristics of high-tech enterprises, selects three influencing factors: research and development (R&D) investment intensity, the number of authorized patents, and the increment of intangible assets. Theoretical analysis is conducted on the impact mechanism and effects of these factors on operational performance. Based on this, empirical analysis is performed using relevant data of Chinese high-tech enterprises from 2011 to 2019. The study indicates that R&D investment intensity has a significant positive promoting effect on operational performance, the number of authorized patents also positively influences operational performance significantly, while the asset-liability ratio of high-tech enterprises has a notable inhibitory effect on operational performance. Finally, relevant recommendations are proposed.

Due to abnormal weather conditions such as high temperature, the management of greenhouse rose farms is getting worse. In order to enhance the competitiveness of these farms, new measures are needed to improve their management performance. Therefore, this study suggests alternatives to improve the efficiency and productivity by identifying the causes of inefficiency of greenhouse rose farms in terms of management performance analysis through DEA analysis and MPI analysis. As a result of DEA analysis, the average TE of farmers increased from 0.867('16) to 0.905('17), but decreased to 0.850 in 2018, indicating that it was inefficient. In order to increase the management efficiency of farmers, efforts to preferentially reduce the costs (equipment, employment labor, fertilizer, facilities, seeds) that cause inefficiencies are needed. As a result of MPI analysis, TECI decreased from 1.044(T2) to 0.939(T3), which was the cause of the MPI decrease, and the TCI was rather increased from 0.958(T2) to 0.969(T3). In other words, it means that the decrease in productivity is due to insufficient utilization of potential production technology rather than the slowing of technological progress. This implies that it is important to provide technical guidance on utilization after technology dissemination.

The purpose of this study is to investigate the difference of performance between banks with electronic-based banking service and banks without electronic-based banking service in Korea. The performance indicators we use are DEA efficiency and profitability such as NI, ROA and ROE. The findings are that the performance of bank with electronic banking service are significantly different from that of bank without electronic banking service in DEA efficiency, financial efficiency(cost and revenue) and profitability. But there are some differences among the type of electronic-based service channel that banks provide. The banking channels comprise two major groups: the traditional channels and e-channels. E-channels provide cost-saving for banks and their clients. Among them, only card-related ATM significantly affects the profitability of banks in the positive direction, and technical efficiency also affects the bank's profitability. But the others do not affect.

This study presents the determinants of R&D efficiency as the focus on CEO's competency, which influences R&D competency and R&D efficiency. The research samples are 6,708 technology-innovation small and medium-sized enterprises (SMEs). The independent variable is the R&D competency(existence of R&D organization, level of R&D personnel, R&D personnel management, R&D investment), the dependent variable is R&D efficiency. The moderator is the CEO's competency(experience level in its own industry, technical knowledge level, technology management strategy, management ability). R&D efficiency measures the relationship between inputs(level of R&D personnel, R&D investment) and outputs(patent applications, prototype) by the DEA. and the determinant analysis uses Tobit regression. As a result of the analysis, the existence of R&D organization and R&D personnel management is positively significant, level of R&D personnel and R&D investment is negatively significant for R&D efficiency. The moderating effect of CEO's competency on the relationship between the R&D competency and R&D efficiency is significant determinants of CEO's experience(experience level in its own industry, technical knowledge level) and technology management strategy. The finding is to measure the efficiency of R&D performance, and to analyze its determinants as the moderating effect of CEO's competency, using the technology appraisal data. In the conclusion session, the limitations of the research and future research directions were discussed.

Previous research on the management of health care organization has heavily focused on health care quality and operational efficiency, whereas this research deals with flexibility, an important strategic priority in the field of operations management. Particularly, this research analyzes the effects that internal and external resources of volume and product flexibilities have on the organization's financial performance. Survey data from various types of sampled domestic hospitals have been collected using the developed questionnaire and analyzed with a regression model. The results show that volume flexibility based on internal resources has not only main effects but also interaction effects with internal and external resources of product flexibility. However, volume flexibility based on external resources is not shown to have any effect on performance. The explanation and managerial implications from the results are discussed.

A measure of managerial ability was derived using DEA, a measure of management efficiency, and the correlation coefficient between discretionary accrual and non-discretionary accrual, net income and operating cash flow standard deviation was used as a proxy for income smoothing. verified. In addition, the manager's compensation was used by taking the natural logarithm of the cash compensation per manager. The analysis results are summarized as follows. The analysis period for hypothesis testing is from 2004 to 2017, as a result of the hypothesis analysis of the correlation with the level of manager's compensation, it was suggested that the income smoothing behavior decreased the performance-based compensation and increased the performance-controlled compensation. This can be said to be the result of indirectly confirming that additional compensation is differentially paid for income smoothing. This study has a contribution to the study by empirically analyzing whether income smoothing affects the relationship between managerial ability and managerial compensation. However, although a number of previous studies empirically analyzed that there are upper and lower bounds for manager compensation, there is limitations that could not be analyzed for asymmetric compensation due to income smoothing is expected to expand.
