  • Purpose: The aim of this study is to evaluate the efficiency of the outpatient clinics in a hospital, using DEA. Methods: Data were collected using an activity-based costing system, medical information system, and annual reports of customer satisfaction management team of a general hospital in a city. The input variables were the number of doctors, the number of nurses, and the number of staffs. The output variables were the number of treatment times, the number of outpatient clinic patients, the total profits from outpatient clinic, the patient's satisfaction score, and the number of re-visit appointments. EMS Window version 3.1 was used to measure the efficiency score and benchmarking analysis. Results: The average efficiency score of 24 outpatient clinics was about 82.01%. Thirteen outpatient clinics had 100% efficiency score among them. The lowest efficiency score was 57.56%. Conclusion: According to these results, we found that, generally, outpatient clinics were operated very efficiently. However, some outpatient clinics had low efficiency and they needed specialized outcome improvement strategies. To increase the efficiency of inefficient outpatient clinics, we will recommend using results of DEA, as a benchmark point of the most efficient outpatient clinics.

  • Jozef Stefan Institute (JSI), TRIGA Mark II reactor employs the homogeneous mixture of uranium and zirconium hydride fuel type. Since its upgrade, a series of fresh fuel steady state experimental benchmarks have been conducted. The benchmark results have provided data for testing computational neutronics codes which are important for reactor design and safety analysis. In this work, we investigated the JSI TRIGA Mark II reactor neutronics characteristics: the effective multiplication factor and two safety parameters, namely the control rod worth and the fuel temperature reactivity coefficient using SuperMC. The modeling and real-time cross section generation methods of SuperMC were evaluated in the investigation. The calculation analysis indicated the following: the effective multiplication factor was influenced by the different cross section data libraries; the control rod worth evaluation was better with Monte Carlo codes; the experimental fuel temperature reactivity coefficient was smaller than calculated results due to change in water temperature. All the results were in good agreement with the experimental values. Hence, SuperMC could be used for the designing and benchmarking of other TRIGA Mark II reactors.

  • A meshless technique using the geometric conservation least-squares method (GC-LSM) was devised to discretize the governing equation of linear elasticity. Although the finite-element method is widely used for structural analysis, a meshless method was developed because of its advantages in a moving grid system. This work is the preliminary phase for developing a fully meshless-based fluid-structure interaction solver. In this study, Cauchy's momentum equation was discretized in strong form using GC-LSM for the structural domain, and the Newmark beta method was used for time integration. The solver was validated in 1D, 2D, and 3D benchmarking problems. Static and dynamic results were obtained. The results are more accurate than those of analytic solutions.

  • The post-evaluation system after construction projects can evaluate estimates of use demand, project cost, and project schedule estimated in the planning phase of construction projects in public sector. Thus, it was introduced in 2000 for the purpose of reduction in future errors during similar constructions by project orderer by referring the post-evaluation results. However, many barriers to the post-evaluation system after construction projects have been reported due to evaluation systems that lack objectivity and reliability and lack of main bodies that utilize the system. Thus, this study derived implications for improvements of the post-evaluation system in Korea by benchmarking building project evaluation system and management as well as utilization systems of developed nations. Then this study conducted a survey with experts who have experienced activities in the post-evaluation committee and members of post-evaluation for public project owners. Therefore it identified the need of installation of specialized post-evaluation institutions as well as functions and work tasks to be taken by specialized institutions. Based on the analysis results, this paper provided revision drafts of related legislations and guidelines to be effective in post-evaluation. Through the study results, many trial and errors can be reduced in similar projects in the future by performing in-depth analysis on large-scale construction projects and repeatedly applied building project practices can be improved to raise technical competitiveness if the specialized institution is installed.

  • This study attempted to do a research on whether local festivals contributed to local economic vitalization in an empirical aspect focusing on Almedalen's case of Sweden has not been discussed in Korea. For this, by analyzing Gotland's sociocultural and economic aspects into 3 steps and evaluating them, the study tried to derive policy implications for benchmarking Almedalen in Korea in the future. As a result of analyzing the economic effect of Almedalen in Sweden into 3 steps, it was shown that in the analysis of resources in Step 1, Almedalen positively affected tourist allurement based on Gotland's beautiful natural landscape. In the evaluation of operation in Step 2, according to the result of examining an increase in population and stabilization with a valuation index related to the activation of local economy, Gotland was steadily seeing a new inflow of population, due to which it can be confirmed that local income increases as various jobs are being created. Finally, as a result of examining the improvement in local image in Step 3, it was shown that as diverse members from all walks of life participated in Gotland's festival, external communication became flexible and the opportunity of social participation increased, which positively affected local image. Based on the study results, the policy implications for benchmarking Almedalen, Sweden's local festival, are as follows: First, selecting an appropriate place for attracting the participation of various people is needed. Second, local festivals should be places for communication to exchange opinions, not specific institute-oriented unilateral provision of information. Third, while advancing local festivals for nonprofit, the efforts to make positive changes in local image are needed.

  • The privatization and commercialization of airports has moved forward at the globa1 level. individual countries have begun to focus less on the public welfare aspect of airports, and to emphasize the need to uncover means of increasing their respective airports economic performance and profitability. Although there is a need for Korean airports to be managed in accordance with this global trend. In order to conduct an accurate comparison and analysis of the managerial performances of the fourteen airports, the WLU(Work Load Unit) a concept which integrates the two outputs of airports, namely, passengers and freight, was employed in this study. Furthermore, in order to overcome the limitations of conducting a financial comparison based solely on WLU, the DEA model was also employed to evaluate airport efficiency: moreover, the benchmarking method was used to establish the input-output goals.
