  • The negative impact of monoculture rubber plantations on biodiversity and associated ecological processes/ecosystem services has led to suggestions on the use of integrated land use systems for rubber cultivation and production in order to ensure environmental sustainability. However, there is paucity of information on the effect of such integrated land use systems on the diversity and abundance of the rubber plantation undergrowth. We evaluated and compared undergrowth plant species composition, richness, abundance, diversity and interaction, in three integrated systems (Rubber-Strelitzia reginae Integrated System - RSrIS, Rubber-Podocarpus nagi Integrated System - RPnIS & Naturally Managed Rubber Plantation - NMRP) with three Rubber Monoculture Plantations (RMP1, RMP2 & RMP3) adjacent to the integrated systems, respectively, at the Investigation and Experiment Station of Tropical Crops, Danzhou, Hainan, China. Undergrowth species density was higher in the rubber monocultures than in the integrated systems except in RSrIS. Species richness and diversity were also higher in the monocultures except in NMRP. Species similarity/interaction between the monocultures and the integrated systems was highest between RMP3 and NMRP. The NRMP proved to be the best model of natural rubber integrated system for the conservation of undergrowth species richness, diversity and interspecific interaction. However, the conservation of undergrowth species in other forms of integrated natural systems can be enhanced by considering the ecology of species to be integrated in terms of their growth characteristics, competitive nature, and ability to grow in association with other species.

  • The main purpose of this paper is to find the phase-in of BIM adoption by focusing on the level of integration. BlM should be aimed at integration and collaboration of all parties furnishing design and construction services to increase the productivity. Therefore, the degree and depth of integration for project collaboration is very important to BlM design process. One of the key advantages of full integration is that is to facilitates the development of detailed information much earlier in the entire design process to improve collaboration among stakeholders. Such integrated use is the ultimate method, but even so, it's not the precondition of BlM. One of the key advantages of relatively low integration as a transition phase is to adopt the BlM earlier than full integration. Such transitional and non-integrated BIM can also reduce the possibility of trial and error in BlM adoption. Therefore, this paper focused on non-integrated use of BlM as a substitute of full IPD by analyzing obstacles in BIM adoption.

  • This article presents an integrated chassis control with electronic stability control (ESC) and active front steering (AFS) under saturation of front lateral tire force. Regardless of the use of AFS, the front lateral tire forces can be easily saturated. Under the saturated front lateral tire force, AFS cannot be effective to generate a control yaw moment needed for the integrated chassis control. In this paper, new integrated chassis control is proposed in order to limit the use of AFS in case the front lateral tire force is saturated. Weighed pseudo-inverse control allocation (WPCA) with variable weight is adopted to adaptively use the AFS. To check the effectiveness of the proposed scheme, simulation is performed on a vehicle simulation package, CarSim. From simulation, the proposed integrated chassis control is effective for vehicle stability control under saturated front lateral tire force.

  • Many researches on use of local ground navigation systems can be found to overcome vulnerability of GNSS. Effective use of an altimeter is proposed in GNSS/DME integrated navigation systems. A weighted DOP based on statistics of measurement error is derived for a given vehicle motion trajectory. From the derived DOP, the vertical error is estimated. By comparing the estimated vertical error with error specification of the altimeter, use of the altimeter is determined in the GPS/DME integrated navigation systems. In order to show effectiveness of the proposed method, 50 times Monte-Carlo simulations were performed for a GPS/DME integrated navigation system. The results show that the proposed method gives more accurate navigation outputs when the number of GPS satellites in view varies.

  • This study presented a model of enterprise that operates an integrated system, and studied about an integrated element of ISO 9001:2000 and ISO 14001:2004 standard. In addition to this, it grasped what the obstacle elements are in use of an integrated system, and analyzed the effect in use of an integrated system through the survey on 58 enterprises that operate an integrated system, From the result of this study, we have known that the obstacle elements in operation of an integrated system are in lack of understanding of process, in lack of execution ability of system, in unfamiliarity of system and lack of willingness of the executives.

  • The study aims to design an integrated remote controller, which is an increasingly essential device in the home, for more convenient use. For this purpose, an alternative user interface (UI) design was developed by applying the user interface system of a popular existing product to an integrated remote control highly usable and easy to learn for domestic use, and the usability was evaluated. For the existing popular product, a cellular phone was selected, the operation method of which is similar to the stick-type integrated remote control for which the user interface design was to be developed in this research. Common characteristics of the UI of the selected cellular phone were derived and the characteristics were applied as much as possible to the design of a stick-type integrated remote control. The prototype of the alternative design, which was simulated with Flash, went through two pilot tests for further improvement before making the final experimental prototype. Based on the results, prototype buttons that improved the feeling of use in terms of physical operation and feedback were made, and the usability of the new UI design of a stick-type integrated remote control for domestic use were evaluated with 41 university students in their 20s. According to the results of the experiment, the newly designed stick-type integrated remote control based on the UI of an existing product may improve the usability of remote controls and the outcome of this study is expected to provide a good model for R&D of new UI designs of stick-type integrated remote controls for domestic use.

  • The integrated sensor module of vehicle combines the functions of rain sensor, auto defog sensor, and sun angle sensor into a single module. These functions originally were applied to work separatively. This integrated sensor module should meet the each performance which appears from the individual modules up to the same level or higher. Therefore, it is important to verify the stability and the accuracy considering the characteristics of the integrated sensor module according to various situations. For the verification, we need to use the actual data of integrated sensor module measured but, a lot of time and money is needed to collect data measured under various circumstances when operating. Thus, through the development of this simulator for the control of the integrated sensor module, we can use it effectively for the initial verification of integrated sensor module by implementing the various situations. In this paper, the simulator for controlling the integrated sensor module which combines vision-based rain sensor, auto defog sensor, auto light sensor, and sun angle sensor has been developed.
