Triage is a practice of accurately prioritizing patients in emergency department (ED) based on their medical condition to provide them with proper treatment service. The variation in triage assessment among medical staff can cause mis-triage which affect the patients negatively. Developing ED triage system based on machine learning (ML) techniques can lead to accurate and efficient triage outcomes. This study aspires to develop a triage system using machine learning techniques to predict ED triage levels using patients' information. We conducted a retrospective study using Security Forces Hospital ED data, from 2021 through 2023 during Hajj period in Saudia Arabi. Using demographics, vital signs, and chief complaints as predictors, two machine learning models were investigated, naming gradient boosted decision tree (XGB) and deep neural network (DNN). The models were trained to predict ED triage levels and their predictive performance was evaluated using area under the receiver operating characteristic curve (AUC) and confusion matrix. A total of 11,584 ED visits were collected and used in this study. XGB and DNN models exhibit high abilities in the predicting performance with AUC-ROC scores 0.85 and 0.82, respectively. Compared to the traditional approach, our proposed system demonstrated better performance and can be implemented in real-world clinical settings. Utilizing ML applications can power the triage decision-making, clinical care, and resource utilization.

Researches recently made in advanced countries into entrepreneurship found that various resources and information are mainly provided to ventures through social capital, which is a resource capital based on a network, and through corporate entrepreneurship. This research is an exploratory study on the effects of social capital and corporate entrepreneurship of new ventures upon their corporate performance, conducted from the standpoint of dynamic capability. For that purpose, a questionnaire investigation was made of 171 venture entrepreneurs in Korea, and the following are the results of an empirical analysis of responses to the questionnaire. First, it was found that social capital, which is a resource capital based on a network, had a significant effect on corporate entrepreneurship. Second, social capital also had a significant effect on ventures corporate performance. Third, corporate entrepreneurship had a significant effect on corporate performance. These results imply that social capital and corporate entrepreneurship have a significant effect on the corporate performance of ventures, which have innate disadvantages concerning the supply of resources. On the other hand, ventures, which encounter relatively more intense demands for change and renovation, can be managed in a sustainable manner just when they adequately accumulate their social capital and utilize their external resources and appropriately conduct their corporate entrepreneurship activities.

Owing to the improved wireless communication technologies, it is possible to provide streaming service of multimedia with PDAs and mobile phones in addition to desktop PCs. Since mobile client devices have low computing power and low network bandwidth due to wireless network, the transcoding technology to adapt media for mobile client devices considering their characteristics is necessary. Transcoding servers transcode the source media to the target media within corresponding grades and provide QoS in real-time. In particular, an effective load balancing policy for transcoding servers is inevitable to support QoS for large scale mobile users. In this paper, the resource weighted load distribution policy is proposed for a fair load balance and a more scalable performance in cluster-based transcoding servers. Our proposed policy is based on the resource weighted table and number of maximum supported users, which are pre-computed for each pre-defined grade. We implement the proposed policy on cluster-based transcoding servers and evaluate its fair load distribution and scalable performance with the number of transcoding servers.

Server virtualization provides abstraction of physical resources to users and thus accomplishes high resource utilization and flexibility. However, the characteristics of server virtualization, such as the limited number of physical resources shared by virtual machines, can cause problems, mainly performance interference. The performance interference is caused by the fact that the CPU scheduler running on the host operating system schedules virtual machines without considering the characteristics of the virtual machine's internal process. To address performance interference, a number of research activities to improve performance interference have been conducted, but do not deal with the fundamental analysis of performance interference. In this paper, in order to analyze the cause of performance interference, we carry out profiling in a variety of scenarios in a virtualized environment based on KVM. As a result, we analyze the phenomenon of the performance interference in terms of CPU scheduling and propose an efficient scheduling solution.

A total of 576 seven-day-old male Ross 308 broilers with an average initial BW of $180{\pm}1g$ were used in a 4 week feeding experiment which included a starter phase (7 to 21 d) and a grower phase (22 to 35 d). Birds were randomly allocated into 1 of 3 treatments with 12 replicates per treatment and 16 birds per pen. The treatments consisted of the following: T1, Control; T2, T1 + 0.1% Creamer (Dongsuh Foods Corporation, Incheon, Korea), and T3, T1 + 0.5% Creamer. The broilers were weighed by pen and feed intake (FI) and the number of living broiler chickens were recorded on d 7, 21, and 35. These information were used to calculate the body weight gain (BWG) and feed conversion ratio (FCR). As results of this experiment, there were no significant differences in the BWG, FCR and nutrient digestibility among the treatments. With regards to meat quality, no adverse effects were observed among the treatments. However, a higher score in redness was observed in T3 than in T1. In addition, the relative weight of breast muscle was reduced in T3 compared with T1. Regardless of the nondairy creamer (NDC) inclusion levels, no negative effects on growth performance and nutrient digestibility were observed. In conclusion, non-dairy creamer could be a kind of fat sources additive in broiler diets, further studies are needed to test the optimum levels of the NDC to be supplemented in broilers diet.

The purpose of this paper is to compare efficiencies, two stage efficiencies, and the reduction of economic growth due to the restraint of $CO_2$ and fossil fuel in two efficiency approach by pointing out the limit of traditional efficiency approach and introducing material balance approach. The efficiencies under the traditional approach and the material balance approach report significant gaps when they are analyzed in detail. Especially, in case not including fossil fuels, the low income countries show the bad performance of production efficiencies, but OECD and high-middle income countries reveal the better performance than that of the low countries. It fails to reflect the reality justly. Based on the material balance approach, the low income countries report the higher performance and the alleviated effect of environmental components for economic growth than OECD's.

Recently many companies have increased their investment in IT because they are increasingly interested in taking advantage of IT and they recognized that it was a very important strategic resource that any organization should manage. That means that the members of a company or an organization realized the importance of IT specialists' coordinating and working in partnership with the business employees to ascertain the high quality and productivity through IT services. While the company looks at IT cost reduction, there is a pressure from users for more support and service from IT departments. That means IT service providers have to offer improved service quality at reasonable cost. To solve the contradictory problem, this paper proposes the application of IT service management. If the IT service management is implemented properly, an organization can attain the tangible and intangible results which are profitable and effective. In Korea, studies on IT service management have focused only on getting a certification and development issues, and there are few papers which accomplished empirical studies. From the viewpoint of Resource-based theory, this study reviews the definition of IT service management and its elements. It has demonstrated empirically how IT service management can have an impact on IT service management performance. As a result, IT service management plays a role in adding and improving the practical use and efficiency of IT service management. In conclusion, this study contributes to support and show the critical point of the previous literatures about IT service management and offers the new practical implications for business sectors.

Recently, due to the development of next-generation computing devices and high-performance network, VDI (Virtual Desktop Infrastructure) is receiving a great deal of attention from IT market as an essential part of cloud computing. VDI enables to host multiple, individual virtual machines that are provisioned from servers located at the data center by using hypervisor. One of the critical issues related to VDI is to reduce the performance difference between virtual machines and physical ones. In this paper, we present a real-time VM monitoring system, called SETMOV, that is able to collect the real-time resource usage information. We also present the performance results using iozone to verify SETMOV.
