In this study, the analytic hierarchy process was applied to construct the assessment indexes for intelligent elderly residential space, and the quantitative evaluation criteria was used to provide references for the construction and improvement of intelligent elderly residential space. Firstly, the present construction status and social needs of the intelligent elderly residential space were summarized by collecting and sorting out the relative literatures, and six assessment frameworks were developed. Then, expert questionnaire was prepared, the degree of mutual influence among the indexes was assessed and the weight corresponding to each framework was calculated.

Over the past decades, Wireless Sensor Networks play a significant role in IoT. Several applications in wide range of industries have attempted to apply this hot technology, including healthcare. However, in current WSN for daily applications, wireless sensors are deployed in easily-touched places in which the malicious user can capture those nodes much easier than before. Especially in medical or healthcare environment, an urgent need of a secure WSN access scheme is requested, especially for the resistant of node capturing attack. This paper proposes a novel authentication information exchanging scheme against node capturing attack in WSN. This paper describes the idea behind this novel scheme, which comes from the association scheme of local sensor nodes. This scheme asks all sensor nodes should periodically contact with GWN and meanwhile execute authentication information exchanging scheme for resist security risk from one node captured by a sophisticated hanker. This paper gives an early study and provides detail discussion of this scheme and validates it in the future.

The purpose of this study is to investigate the determinants that influence relationship network between travel agents and hot spring industry, then we utilized in this study both social exchange theory and the relationship network to explore the application of the travel agencies and hot spring industry's relationship network. In this research, we began by reviewing relevant theoretical literature, followed by establishing a conceptual framework and research hypotheses based on existing literature; the next step we conducted in-depth interviews with spring industry and travel agencies in order to explore how the hot spring industry's development is and how the use of the alumni network is. Based on our research findings, the hot spring industry's alumni network is focused on the individual's interpersonal interaction. The social network is the medium for network continuity and for closing deals. However, the economic concept is more important than social rationality. On top of that, we point out in this study both the management implications and recommendations for future research. This study also provide suggestions about relationship marketing strategies and longterm relationship establishment for the hot spring industry.

From the perspective of sustainability, this paper analyzes how stakeholders realize sustainable social innovation through co-creation. Through literature and case analysis, based on the group classification of social networks, this paper proposes three elements of social innovation: place creation, situation creation and relationship structure, and further sorts out the co-creation of meaning co-creation, behavior co-creation and value co-creation. The research shows that co-creation is a practical activity based on cultural identity, group interaction and resource integration, and stakeholders can achieve the goal of sustainable social innovation through meaning co-creation, behavior co-creation and value co-creation.

The global economy is experiencing a new stage of development. And how to establish a sound Product service system in the sustainable development period to bringing social and economic benefits and realizing sustainable economic and social development has become the major research topic. Service-dominant logic is permeating into the design of complex systems, which is an important pillar of service design, yet product-service systems have not been the mainstream, and there are no any other methods can deal with that transportation. In the context of sustainable development, the purpose of this paper is to explore how to optimize the Product service system with service as the leading factor and with service design as the guidance. In addition, the design method of this study can increase the value beyond the product and service layer, and solve the problem that lack of design literature in product and service system, and add the relevant information for it.

Based on the power system parameter optimization of the optimization problem of genetic algorithm, genetic algorithm was adopted to optimize the control algorithm parameters. Then the power of fuel cell, the number of lithium batteries as well as the motor power were taken as the design variables, power performance and economic efficiency as the optimization objectives, and then the maximum gradient and maximum speed were regarded as the constraint conditions. The relevant parameters in the control strategy of the whole vehicle power system were obtained after genetic optimization. The deviation of the maximum speed was 0.07%, which basically leveled off. The range increased from 283.4km to 309.1km, which somewhat increased. While the gradeability increased by 16.2%, which greatly improved. The optimization results indicated that it was feasible and reliable to apply this optimization scheme to the parameter optimization of hybrid fuel cell automobile power system.

Taitung Jinlun Hot Spring Area in Taiwan is rich in hot spring resources and vast hinterland. After the hot spring area is completed, the application for hot spring development and geothermal power generation continues to increase. Under the premise of ensuring the sustainable use and operation of the hot spring industry, it is necessary to establish a hot spring monitoring well to monitor the impact of development activities on hot spring resources, and to protect the hot spring resources. The monitoring well was set on the left bank of Jinlun red bridge. The monitoring well depth is 94 meters, which is high temperature, high pressure and self-injection well. The hot spring pH is 8.7 and water temperature is 72.1 degrees. The water quality is sodium bicarbonate and outflow is 0.00146 cms. The water discharge test by the Jinlun Hot Spring monitoring well shows that the water level in the well is between 54.4 and 58.1 meters in elevation when the wellhead valve is closed. Monitoring the opening of the well valve, the pressure is released due to the hot spring water, and the water level is reduced from 58.1 meters to 43.75 meters. Therefore, the monitoring of the hot spring water in the well can be ejected from the surface of the ground at a height of 14.35 meters.

The provision of computing facilities and services has been revolutionized by cloud computing where virtual resources that are scalable are increasingly offered as services over the internet. Starting out as provision of Software as a Service (SaaS), cloud computing has evolved to Platform as a Service (PaaS) whereby scalable, large-scale computing resources such as data centers are offered as services to Infrastructure as a Service (IaaS) where a complete computing infrastructure and computing resources are integrated as a service to clients. The application model of hybrid clouds including public clouds and private clouds is current mainstream of cloud technology with various advantages such as elastic computing resource, load balance, geo-replication (like those from public cloud), safety, privacy and cost effectiveness (like those from private cloud). Based on previous work on cloud-based electronic design automation for integrated circuit design, implementation of an e-learning platform in hybrid clouds using Eucalyptus private cloud and Openshift public cloud is performed in this study. There are eight virtual machines in private cloud and the same number of virtual machines in public cloud. Each virtual machine in the hybrid clouds is running with Linux operating system, Nginx HTTP server, Wordpress CMS, and shared MySQL database. In hybrid clouds outside sixteen virtual machines, an additional Nginx reverse proxy is running for load balancing due to mass visiting request. In this study, e-learning platform is developed with using Wordpress CMS and PHP language to realize various functions such user identification, WYSIWYG course authoring, video & audio learning material with text, online quiz, and discussion. The Eucalyptus, Openshift, Nginx, Wordpress, and MySQL utilized in this study are all free open source codes that much improvements of the e-learning platform in hybrid clouds is very possible for future works.
