The display industry plays an important role in the entire Korean economy. Few empirical research has analyzed the efficiency of display companies although it is necessary to measure the management efficiency for more efficient operation and more strengthening competitiveness of them. The purpose of this paper is to measure and analyze their efficiency of the Korean listed display companies using a hybrid ANP and DEA model. In this paper, we analyzed the 44 listed companies consisted of 7 listed on KOSPI and 37 listed on KOSDAQ at the end of 2010. In order to determine the input and output variables of DEA, the ANP model was applied to evaluate the importance of input and output variables. The benchmarking companies and efficiency value for the display firms with inefficiency were also provided to improve the their efficiency.

The dynamic capabilities of sensing market signals, creating new opportunities and reconfiguring resources and capabilities to new opportunities in a rapidly changing economic environment determines the competitiveness of the enterprise to create added value and survival. This study conceptualized a two-stage performance measurement framework based on the casual model of resource (input)-process-performance (output). We have developed a 'Process capability index' that reflect the dynamic capabilities factors as a key intermediary product linking resource inputs and performance outputs in enterprise performance measurement. The process capability index consists of four elements : manpower (level of human resource), operation productivity, structure and risk management. The DEA (Data Envelopment Analysis) model was applied to the developed performance indicators to analyze the branch office performance of a telecom company. Process capability efficiency (stage 1) uses resource inputs to reach a certain level of process capabilities. In performance result efficiency (stage 2), the process capabilities are used to generate sales revenues and subscribers. The two-stage DEA model derives intermediate output values that optimize the individual stages simultaneously. Some branch offices in the telecom company have focused on process capability efficiency or some other branch offices focused on performance result efficiency. Positioning map using two-stage efficiency decomposition and benchmarking can help identify the sources of inefficiencies and visualize strategic directions for performance optimization. Applications of two-stage DEA in conjunction with the case study that are meaningfully used in performance measurement areas have been scarce. In particular, this paper has the contribution to present a new performance measurement model considering the organization theory, the dynamic capabilities.

This study suggests the dynamic value chain model, that will be able to not only show changing processes to organization's significant capital by integrating an individual, implicit, and explicit knowledge which affect organizational decision making, but also distinguish the key driver for raising organizational competitive power because it makes possible to analyze sensitivity of performance along with decision making alternatives and policy changes from dynamic view by connecting knowledge management capability, knowledge management activity, and relations with organizational performance with specific strategic map. Recently, a lot of organizations show interest in measuring and evaluating their performance synthetically. In organizations taking knowledge management, they introduce effective value chain model like a dynamic balanced scorecard (DBSC), and therefore they can reflect their knowledge management condition as well as show their changes by checking performance of established vision and strategy periodically. Furthermore, they can ask for their inner members' understanding and participation by communicating with and inspiring their members with awareness that members are one of their group, present a base of benchmarking, and offer significant information for later decision making. The BSC has been a successful framework for measuring an organization's performance in various perspectives through translating an organization's vision and strategy into an interrelated set of key performance indicators and specific actions. The BSC, while having significant strengths over traditional performance measurement methods, however, has its own limitations, due to its static nature, such as overlooking two-way causation between performance indicators and neglecting the impact of delayed feedback flowing from the adoption of new strategies or policy changes. To overcome these limitations, this study employs SD, a methodology for understanding complex systems where dynamic feedback among the interrelated system components significantly impact on the system outcomes. The SD simulation model in the form of DBSC would serve as a useful strategic teaming tool for facilitating an organization's communication process through various scenario analyses as well as predicting the dynamic behavior pattern of their key performance measures over a future time frame. For the demonstration purpose, this study applied the DBSC model to Prototype of Korea manufacturing and service firm.

The purpose of this study is to analyze the actual condition of the already established rural theme park, draw the weak and strong points, and come up with an efficient performance plan for Changwon Persimmon Theme Park through the benchmarking of the best overseas case. According to the analysis, it is necessary to introduce a facility and a program for family customers as a plan for promoting Changwon Persimmon Theme Park. It is required to secure safety through public operation and management, improve scalability of the facility through the establishment of multi-functional complex facility, and come up with a plan for operating a special program associated with local resources. Therefore, this study drew three activation factors: the establishment of operation and management system, the development of operation contents by facility, and the establishment of operation in each area. First, to establish the operation and management system, it is necessary to classify the organization of the theme park into the operation business area and into operation & management area by job function. Secondly, it is necessary to establish a special program in consideration of space and facility, suggest a differentiated plan for operation contents, and create a facility operation plan and program for Changwon Persimmon Theme Park. Lastly, to operate and manage Changwon Persimmon Theme Park smoothly, it is necessary to set the theme park space as open collaboration space which the local residents can share and participate in by avoiding the conventional administration-based business performance and operation. This study suggested the plan for establishing an operation and management system for Changwon Persimmon Theme Park and its operation, the establishment of a special program, a business performance strategy, and the use of internal and external spaces of the theme park.

The purpose of this study is to review the trend in comparative education research related to curriculum published in the Korean Journal of Comparative Education, and to critically analyze its characteristics from the postcolonial perspectives. In this study, I analyzed 61 articles published in this journal from 1995 to 2016. The result showed that comparative studies related to curriculum were conducted mainly by benchmarking policies or contents related to curriculum and textbooks of Western countries including North America and Europe as well as Japan which colonized Korea. In addition, although Korea has been changing into multicultural society, studies on Asian countries such as China and Vietnam which are the nationalities of many foreigners living in Korea were rare. Based on the results, this study suggested that the expansion of comparative education research subjects, overcoming of coloniality in comparative education, and ontological reflection of comparative education researchers are necessary.

Lead-alloys are very attractive nuclear coolants due to their thermo-hydraulic, chemical, and neutronic properties. By utilizing the HELIOS (Heavy Eutectic liquid metal Loop for Integral test of Operability and Safety of PEACER$^2$) facility, a thermal hydraulic benchmarking study has been conducted for the prediction of pressure loss in lead-alloy cooled advanced nuclear energy systems (LACANES). The loop has several complex components that cannot be readily characterized with available pressure loss correlations. Among these components is the core, composed of a vessel, a barrel, heaters separated by complex spacers, and the plenum. Due to the complex shape of the core, its pressure loss is comparable to that of the rest of the loop. Detailed CFD simulations employing different CFD codes are used to determine the pressure loss, and it is found that the spacers contribute to nearly 90 percent of the total pressure loss. In the system codes, spacers are usually accounted for; however, due to the lack of correlations for the exact spacer geometry, the accuracy of models relies strongly on assumptions used for modeling spacers. CFD can be used to determine an appropriate correlation. However, application of CFD also requires careful choice of turbulence models and numerical meshes, which are selected based on extensive experience with liquid metal flow simulations for the KALLA lab. In this paper consistent results of CFX and Star-CD are obtained and compared to measured data. Measured data of the pressure loss of the core are obtained with a differential pressure transducer located between the core inlet and outlet at a flow rate of 13.57kg/s.
