Purpose - This study aims to identify the internal capabilities that export companies need to possess in order to utilize FTAs and to propose ways to expand their export performance through them. To achieve this goal, the study analyzed the internal factors that affect FTA utilization from a resource-based perspective, such as Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export, based on prior research on corporate capabilities in the field of management and FTA-related research. The study ultimately aims to confirm whether a company's FTA utilization contributes to its export performance through the management and response to its internal factors for FTA utilization. Design/methodology - To achieve the research objective, this study conducted a literature review related to FTA utilization and identified the internal factors of companies that affect FTA by classifying them into Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export Based on this, a final research model was developed, hypotheses were set through a preliminary study survey, and conclusions were drawn by analyzing the data of 312 companies. Findings - The empirical analysis results indicate that Origin Management Competency and Contract Management Competency have a positive impact on FTA utilization, while Information Acquisition Competency and Commitment to Export do not have a statistically significant impact on FTA utilization. Based on these findings, this study suggests measures for efficient FTA utilization for companies that want to utilize FTAs. Additionally, FTA utilization has a positive impact on export performance. In other words, the extent to which companies utilize the signed agreements has a positive impact on their performance. Based on these results, this study identifies the characteristics of companies that want to utilize FTAs and proposes measures for future efficient FTA utilization. Originality/value - This study has confirmed that in order for companies to utilize FTAs, they must meet the requirements of the FTA. To this end, the study has concluded that it is important to manage and address internal factors such as Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export to increase FTA utilization. Based on these results, it can be confirmed that it is essential for companies to have an understanding and management of the internal factors that satisfy the requirements of the FTA in order to utilize the FTA.

Purpose: This study was conducted to construct evidence based clinical guidelines and to develop nursing process based performance measures for prevention and management of pressure ulcers, falls and pain. Method: Clinical guidelines were drafted through a comprehensive review of relevant literature, national guidelines and hospital protocols. The proposed guidelines were reviewed by a panel of experts and 90 hospital nurses, and refined on the basis of their suggestions. Nursing process based performance measures were developed based on the clinical guidelines and content validity was examined by surveys from 90 hospital nurses. Results: All items, except timetable for position change and pressure ulcer nursing record, in the guidelines for prevention and management of pressure ulcer were appropriate. Most items, except fall risk assessment tools, were appropriate for the guidelines of fall prevention. All other items, except the purpose of pain management, were appropriate for the guidelines of pain management. Performance measures developed in this study were acceptable as a tool to evaluate quality of nursing care. Conclusion: Nursing process based performance measures provide important indicators to monitor whether necessary nursing care is implemented and can be used as the primary resources to improve quality of nursing services.

Purpose: The purpose of this study was to develop a web-based education program on control vancomycin-resistant enterococci (VRE) infections and to identify the effects of the program on knowledge and performance of nursing students. Methods: The web-based VRE infection control education program was developed by using the network-based instructional systems design model. The nursing students in the experimental group could access this web-based education program at any time, and as many times as they wanted, during the clinical training period. Effects were evaluated by assessing knowledge and performance of VRE infection control measures during the clinical training period. Results: The contents of the education program included diagnosis, transmission, and treatment of VRE, contact precautions, hand washing, personal protective equipment, environment management, and quizzes. The lecture portion was filmed in a virtual screen studio using flash animation, video, and sound effects, and it was uploaded on an internet site. The knowledge and performance scores of the experimental group after using the education program were significantly higher than those of the control group. Conclusion: The results suggest that the web-based VRE infection control education program is an effective educational method to enhance knowledge and performance of VRE infection control measures.

Most of the navigation in the vehicle has been developed based on a complex structure of PSF(Physical Storage Format) files, making it difficult to support incremental map updates. DB-based navigation is drawing attention as a next-generation navigation method to solve this problem. In DB-based navigation that supports incremental map updates, data fragmentation due to continuous map data updates can increase data access costs, which can lead to a decrease in search performance. In this paper, as one of the performance enhancement methods of DB-based navigation that supports incremental map updates, data fragmentation prevention techniques were presented and the performance improvement effect was verified through actual implementation.

This article aimed to introduce 'risk sharing' schemes for pharmaceuticals between drug manufacturers and healthcare payer. Published literature review was undertaken to summarize risk sharing concepts and collect information on existing scheme examples in other countries focusing on new anticancer drugs. Risk sharing schemes could be categorized into health outcomes-based and non-outcomes (financial) based ones. Outcome-based schemes could be broken down into performance-linked reimbursement and conditional coverage. Performance-linked reimbursement can be further broken into outcomes guarantee and pattern or process of care and conditional coverage included coverage with evidence development and conditional treatment continuation schemes. Non-outcome based schemes included market share and price volume at population level, and utilization caps and manufacturer funded treatment initiation at patient level. We reviewed the fifteen examples for anticancer drugs that risk sharing agreements in response to the inherent uncertainties and increased costs of eleven anticancer drugs. Of them, eight cases were coverage with evidence development schemes. The anticancer drugs except bevacizumab and cetuximab were all listed on the national health insurance formulary in Korea, with reimbursement criteria defined on the basis of approved indications and administrations. Risk sharing approach may be a useful tool to ensure values for drug expenditure, but there are a number of concerns such as high administration costs, lack of transparency and conflicts of interest, especially for performance-based health outcomes reimbursement schemes.

In this paper, an enhanced time-based registration method is proposed. The method reduces the registration cost when a mobile terminal stays in a cell for a long time. We also analyze the performance of the proposed method numerically. In the analysis, we assume Poisson call arrival distribution and exponential cell resident time. From the analysis we calculate the optimal time-interval. Additionally, limit cost analysis is made to investigate the behaviors in the limit conditions. To compare the performance of the proposed method with the original time-based registration method, we analyze the performance of the original time-based registration method. In the comparisons, we see that the proposed enhanced time-based registration method has better performance and is applicable to the PCS systems.

This paper compares the four selections of performance used in the application of genetic algorithms (GAs) to automatically optimize multispectral pixel cluster for unsupervised classification from KOMPSAT-3 data, since the selection among three main types of operators including crossover and mutation is the driving force to determine the overall operations in the clustering GAs. Experimental results demonstrate that the tournament selection obtains a better performance than the other selections, especially for both the number of generation and the convergence rate. However, it is computationally more expensive than the elitism selection with the slowest convergence rate in the comparison, which has less probability of getting optimum cluster centers than the other selections. Both the ranked-based selection and the proportional roulette wheel selection show similar performance in the average Euclidean distance using the pixel clustering, even the ranked-based is computationally much more expensive than the proportional roulette. With respect to finding global optimum, the tournament selection has higher potential to reach the global optimum prior to the ranked-based selection which spends a lot of computational time in fitness smoothing. The tournament selection-based clustering GA is used to successfully classify the KOMPSAT-3 multispectral data achieving the sufficient the matic accuracy assessment (namely, the achieved Kappa coefficient value of 0.923).

The existing underwater vehicle controller design is applied by linearizing the nonlinear dynamics model to a specific motion section. Since the linear controller has unstable control performance in a transient state, various studies have been conducted to overcome this problem. Recently, there have been studies to improve the control performance in the transient state by using reinforcement learning. Reinforcement learning can be largely divided into value-based reinforcement learning and policy-based reinforcement learning. In this paper, we propose the roll controller of underwater vehicle based on Deep Deterministic Policy Gradient(DDPG) that learns the control policy and can show stable control performance in various situations and environments. The performance of the proposed DDPG based roll controller was verified through simulation and compared with the existing PID and DQN with Normalized Advantage Functions based roll controllers.

In this study, the weight and the connections type layout of low-rise eccentrically braced frame (EBF) have been optimized based on performance-based design method. For this purpose, two objective functions were defined based on two different aspects on rigid connections, in one of which minimization and in the other one, maximization of the number of rigid connections was considered. These two objective functions seek to increase the area under the pushover curve, in addition to the reduction of the weight and selection of the optimum connections type layout. The performance of these objective functions was investigated in optimal design of a three-story eccentrically braced frame, using two meta-heuristic algorithms: Enhanced Colliding Bodies Optimization (ECBO) and Enhanced Vibrating Particles System (EVPS). Then, the reliability indices of the optimal designs for both objective functions were calculated for the story lateral drift limits using Monte-Carlo Simulation (MCS) method. Based on the reliability assessment results of the optimal designs and taking the three levels of safety into account, the final designs were selected and their specifications were compared.
