  • Understanding the microbial community and function are crucial knowledge for crop management. In this study, bacterial and fungal community structures both rhizosphere and endosphere in kiwifruit were analyzed to gain our knowledge in kiwifruit microbiome. Microbial community in rhizosphere was less variation than endosphere community. Functional prediction results demonstrated that abundance of saprotrophic fungi was similar in both rhizosphere and endosphere, but potential pathogenic fungi was more abundance in endosphere than in rhizosphere. This finding suggested that maintain healthy soil is the first priority to protect the host plant against biotic stresses.

  • This paper presents a numerical evaluation of the flow rate of air conditioner outdoor unit as function of shroud design parameters. To determine the optimal design parameters, we investigated the flow rate by changing bell mouth height, fan height, fan guide height, fan width. The evaluation of the relative priority of the design parameters was performed to choose three important parameters in order to use a response surface method. The flow rate of the optimum model, compared to that of the base model, was increased by about 6.25%.

  • According to the need for objectivity and convenience the whole planning process is devided into a secries of 8 systematic stages. But it is an unending upward spiral of incremented efforts toward improvement. So many activities should be carried out concurrently, providing a mutual supportive flow back and forth between various stages of the process depending on local conditions and requirements. The eight stages are: (1) Planning the Planning and Developing Planning Competence (2) Statements of Policy and Broad Goals (3) Data Gathering (4) Priority Statement (5) Statement of Major Alternative Proposals (6) Development of Detailed Plan (7) Implementation as a Part of the Planning Process (8) Evaluation The frame and function of the planning machinery must be adjusted to local conditions, and also flexibility is desirable, especially at the start, when adaptations are more necessary and more frequent.

  • This paper presents a system for a billing system that can be used to motet dynamic priority users in IntServ operation over DiffServ network. Our billing system is designed to authentication, accounting, metering using Remote Authentication Dial In User Service (RADUS). we present packet pricing model of three different service classes which is Best, Good, Default service in IntServ operation over DiffServ network. The packet pricing model can present users with prices and charges in a way that encourages efficient network use. In this model, the RSVP is used, which is resource management to QoS routing function in the IntServ network.

  • In DQDB networks, the bandwidth can be increased considerably be using the EN(Erasure Node) algorithms and DR(Destination Release) algorithms. However, the important issue in implementing them is using method of extra capacity fairly. To improve it, this paper proposes AEN(Adaptive Erasure Node) algorithm which erasure function is activated by network traffic load. Its functional architecture consists of SESM, RCSM, LMSM in addition to the basic DQDB state machines (DQSM, RQM). The SESM and RCSM state machines are placed in front of the DQSM and RQM state machines in order for the node to take advantage of the newly cleared slots. This paper also presents some simulation results showing the effect of AEN algorithm on access delay, throughput and segment erasing ratio in the single and multiple priority networks. The results show that the AEN algorithm offer the better performance characteristics than existing algorithms under overload conditions.

  • In this study 'forest design in waterside unused land' of 'waterside area' in the specificity that multilateral, including landscape, recreation, social and environmental aspects in the space, taking into account by multiple factors :Raise 'practicality' than a functional management and police to hang out with, each element is usually way to improve the beauty. There is currently carried out waterside green area creation, which is artificial plantation and open spaces only emphasizing 'landscape' with lacking multi-function purpose, as a 'forest design in waterside unused land' strategy but it should be lowered by performance in this strategy. And the study suggested a strategy which prepared cultural and social infrastructure to be able to attract different fund and build local character as an alternative demand plan considered environmental character as a top priority.

  • This study proposes a efficient technology to control the optimal trajectory planning and real-time implementation method which can perform autonomous travelling for unmaned factory automation. Online path planning should plan and execute alternately in a short time, and hence it enables the robot avoid unknown dynamic obstacles which suddenly appear on robot's path. Based on Route planning and control algorithm, we suggested representation of edge cost, heuristic function, and priority queue management, to make a modified Route planning algorithm. Performance of the proposed algorithm is verified by simulation test.

  • The property of the mobile phone is taking important role to choose it. In the present situation, exploring, comparing and analyzing the important properties of regular mobile phone(feature phone) and smart phone are very meaningful study. Therefore, the survey was carried out to get the properties of feature phone and smart phone and analyze the difference of those phones. And proposed the important variables for customer satisfaction which must be given priority. The result showed that 'design' and 'Quality' are important to both mobile phone user groups. The problems with mobile phones currently in use were 'poor performance' to feature phone users and 'expensive charge' and 'poor A/S' to smart phone users. Two groups also showed significant difference with the customer satisfactions, and smart phone user group showed higher satisfaction. For smart phone user group, four factors are induced from the properties but 'Hardware Quality' (representing 'call Quality', 'A/S', 'Convenience to use', 'Battery life') and 'Design & Function'(representing 'Internet', 'Convergence Functions', 'Design, 'Color') have significant and positive effects on Customer Satisfaction.
