The improvement in the management of Public Health through the public health management system (PHMS) has become a bottleneck. Although the management of a large number of patients' information has been studied, their networking aspect remains a challenge in prompt assessment of their records. With a view to bringing about an efficient management system, the Software Defined Networking (SDN) Technology came up with an interesting idea to properly manage network operation flow. The SDN technology enables the controller(s) to regulate the control flow in a logical manner through its intelligent control. This paper proposed a framework based on SDN to optimise the performance of large-scale PHMS. As a measure for better healthcare records, the proposed technology provides a reliable system to address huge patients' data request that is imminent. This article motivates experimentally, the need to despise the historical fear of new technology in PHMS as against the conventional/old practices.

In this paper, based on the concept of Havrda-Charvat-Tsallis entropy, fuzzy entropy measure is introduced in the setting of fuzzy set theory. The properties of the new fuzzy measure are investigated in a mathematical view point. Several examples are applied to illustrate the performance of the proposed fuzzy measure. Comparison with several existing entropies indicates that the proposed fuzzy information measure has a greater ability in discrimaniting different fuzzy sets. Lastly, the proposed fuzzy information measure is applied to the problem of MCDM (multi criteria decision making) based on TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method under bipolar fuzzy environment. Two models are constructed to obtain the attribute weights in the cases that the information attribute weights is partially known and completely unknown. An example is employed to show the effectiveness of the new MCDM method.

This study approaches the relative position of a company in technological network based on patent citation of the cloud computing industry. It integrates the PCA with the patent family to obtain a complete data set for later analysis. After that, the Technology Knowledge Redundancy in the PCN has TKS/TKR indicators for analysis. Moreover, the changes in the technological positions before and after patent transfer revealed three patent acquisition strategies namely: strengthening foothold by enhancing barriers, a cash cow for non- practicing entities (NPE), and a shortcut for peripheral and new entrants. After patent transfer, more companies obtained high and low positions in the technological network and gained abundant and decreased resources. This fact reveals that the unchanged dichotomy in technological transfer. In order to obtain high positions in the technology industry and gain cooperation opportunities, marginal or new entrants of the technological field would need to acquire patents with high TKS/TKR.

An emergency department service system provides a medical service to patients who are prioritized for medical care, starting with triage categories and ending with the discharge formalities. In this paper, the emergency department service system is modeled as a fuzzy multi-state network called emergency department service network (EDSN). Each arc is a workstation with a fuzzy multi-state situation because of the vagueness in measuring human capability, and each node is represented as a waiting area. The main aim of this paper is to evaluate the system reliability, that is, the possibility that an emergency department service system can provide necessary treatments to the patients. Since each workstation is fuzzy multi-state, we proposed a method to generate the membership function by utilizing by statistical parameters, such as average and standard deviation. A practical example with statistical data taken from a Taiwan hospital to evaluate the system reliability is demon-strated.

Cultural Intelligence (CQ) has been identified as a critical competency in responding to globalization. Recently, the number of students with international experience has increased because international experience has been viewed as one method of developing CQ. During the process of CQ development, negative psychological factors might influence the results. This study discusses CQ from a psychological perspective. The purpose of the study is to examine the relationship between international experience and CQ, and the moderating effect of acculturative stress. This quantitative research used a survey approach to collect the data. Snowball sampling, a convenience sampling approach, selected Taiwanese students with international experience as the subjects. Correlation analysis and hierarchical regression analysis were used to analyze the hypotheses. The results remind us that understanding the knowledge of a culture and engaging deeply in a culture are the value of experiencing an intercultural context.

Most research on housing price modeling only utilizes a single environmental factor. The goals of this paper are to select the appropriate factors and to identify the influencing patterns for 3 major types of real estates through model building that includes 49 housing factors. The datasets were composed by 33,027 transactions in Taipei City from July 2013 to the end of 2016. The models utilized were Decision Tree (DT), Artificial Neural Networks (ANN), Random Forest (RF), Model Tree (MT), and Multiple Regression (MR). The importance of each factor derived from the above 5 models is thus analyzed and ranked for the 3 housing types. Also, this paper adopts Generalized Additive Models (GAM) to derive the patterns of important factors influencing housing prices that includes increasing, decreasing, and non-linear relationships.

By applying the notion of the efficient Banzhaf index, any additional fixed utility should be distributed equally among the players who are concerned. In many applications, however, this notion seems unrealistic for the situation that is being modeled. Therefore, inspired by the notion of the weighted allocation of non-separable costs (WANSC), we adopt weight functions to introduce a modification of the efficient Banzhaf index, which we name the weighted Banzhaf index. In order to present the rationality of the weighted Banzhaf index, we adopt some reasonable properties to characterize the weighted Banzhaf index. Based on different viewpoints, we further define excess functions to propose alternative formulations and related dynamic processes for the weighted Banzhaf index and the WANSC respectively.

A procurement model is built based on the expected utility theory when purchase price is uncertain. The optimal purchasing strategy for a risk-averse manufacturer is obtained. And the influence of different factors on the optimal purchasing strategy is analyzed. The results show that the relationship between the optimal purchasing quantity and the degree of risk aversion depends on the relative level of procurement cost at that time. As the price volatility or drift rate increases, the purchase amount in the early stages will increase, and the purchase amount in the later stages will decrease. Finally, it is demonstrated that the procurement strategy of a risk-neutral manufacturer is a bang-bang strategy, which is different from the procurement strategy of a risk-averse manufacturer.

This study solves a multi-project, multi-mode, and resource-constrained project scheduling problem. Multi-mode means that the activities in a project can be accomplished in one out of several execution modes, each of which represents an alternative combination of resource requirement of the activity. The present study considers the case that the resources need to be allocated first to individual projects by the upper-level manager, and then the project manager of each project schedules the project to optimize its outcome. In view of such a hierarchical decision-making structure, this study uses bi-level decentralized programming to model the problem. The proposed solution procedure employs combinatorial auction mechanisms to determine resource allocations to projects. A regular combinatorial auction and a fuzzy combinatorial auction are used, respectively, for cases of hard and soft capacity constraints. The proposed solution procedure is evaluated by comparison with the results reported in the literature.

This paper takes a contingent claim approach to the market valuation of a banking firm’s equity. A model is presented that explicitly takes into account the following: (i) the bank is regret-averse; (ii) the earning-asset portfolio of the bank includes regular banking loans, default-free liquid assets, and shadow banking wealth management products; and (iii) imposing heightened capital requirements on the bank emerges. We argue that it may not be regretful for the bank to conduct the WMPs, implying that these activities have been increasing over time. Increases in WMPs or capital requirements decrease the bank interest margin, which makes the bank more prone to loan risk-taking, thereby adversely affecting banking stability.
