Not many years ago, people found the contemporary technology expensive and difficult to use in collaborative type of meetings. Today, with the technology advanced to high standards and accessible at cheaper price, its adaption is becoming more and more ubiquitous with wide range of applications. Today's meeting rooms are not just plain old telephone systems with microphones and speakers. Today's meeting rooms are smart and intelligent. They can identify the participants; they can provide natural view of remote participants; they can proactively manage resources for collaboration and so on. More effective collaboration is possible with deployment of devices like high-definition cameras, advanced displays, sensors, gigabit networks, trackers, pointers, and high-end audio devices. Devices alone are not enough in the meeting rooms. We need software infrastructure to manage the devices and meeting contexts. One such software infrastructure is SMeet, a Smart Meeting space, which we have developed to provide an effective multi-party remote collaboration environment. Networked display systems are used in such advanced collaboration environment for better visualization. In this paper we discuss a novel approach to control and manage networked display systems in SMeet environment.

With various sensor network and ubiquitous technologies, we can extend interaction area from a virtual domain to physical space domain. This spatial interaction is differ in that traditional interaction is mainly processed by direct interaction with the computer machine which is a target machine or provides interaction tools and the spatial interaction is performed indirectly between users with smart interaction tools and many distributed components of space. So, this interaction gives methods to users to control whole manageable space components by registering and recognizing objects. Finally, this paper provides an effective spatial interaction method with template-based task mapping algorithm which is sorted by historical interaction data for support of users' intended task. And then, we analyze how much the system performance would be improved with the task mapping algorithm and conclude with an introduction of a GUI method to visualize results of spatial interaction.

The increasing penetration of distributed energy resources on the distribution networks have brought a number of technical impacts where voltage and thermal variations have been identified as the dominant effects. Active network management in distribution networks aims to integrate distributed energy resources with flexible network management so that distributed energy resources are organized to make better use of existing capacity and infrastructure. This paper propose active solutions which aims to solve the voltage and thermal issues in a distributed manner utilizing a collaborative approach. The proposed algorithms have been fully tested on a distribution network with distributed generation units.

The e-Science for High Energy Physics is to study high energy physics anytime and anywhere even if we are not on-site of accelerator latboratories. The concepts are 1) data production, 2) data processing and 3) data publication. The data production is to do remote control and take shifts remotely. The data processing is to run jobs anytime, anywhere with grid farms. The data publication is to work together to publish papers using collaborative environment such as EVO (Enabling Virtual Organization) system. We apply this concept to high energy physics, espessically, CDF experiment and show the results.

A relatively wide range of weed technology concerning sound herbicide development, its formulation exploitation, and application techniques was extensively reviewed in accordance with least inputted sustainable agriculture. Herbicide plays an integral part of farmers' cultural practices in Korean agriculture like rest of world over. Weeds are more obstacle to the adaptation of more sustainable agriculture system. Because weeds dictate most of the crop production practices, weed scientists must become the leaders of collaborative integrated approaches to agriculture systems research. Feasible ways to minimize herbicide input involve the positive introduction of low-rate selective chemistries, innovative formulations, biological herbicides and newly developed application technology. Since herbicide will remain to be a core position in weed management for the foreseeable future, research is needed to optimize herbicide application technology and to minimize their impact on the environment. Public concerns and regulatory pressures on agricultural chemicals are likely to strengthen throughout this decade and coming. Researchers, pesticide manufacturing industries and regulatory authorities have to work together more closely, leading to understand each other better, as well as the needs of our customers and those of society. To be taken extensively, weed control management practices in the future have to be accepted such a way the respective demands of environment, society and economics are entirely matched.

Objectives: This article reviewed researches on intersectoral partnership of school health programs to suggest importance, current status and development plan of those. Methods: Domestic research papers were screened though Research Information Sharing Service (RISS), Koreanstudies Information Service System (KISS), Medical Library Information System (MEDLIS), Korean Medical Database (KMbase), and digital national assembly library. International papers were searched mainly via Pubmed. Results: Since intersectoral partnership is effective, comprehensive and universal approach for school health programs, many collaborative programs are universally progressing in various domain including smoking, alcohol, mental health and sexual behavior. On the other hand, intersectoral partnership of school health programs in Korea is still in the beginning stage, and there are few intersectoral partnerships. Moreover, there are several limitations including top-down approach, passive participation and lack of studies on the effect of intersectoral partnership. However, intersectoral partnerships in school health program including tuberculosis control system in school or WEE project are in progress, so it is worth looking forward in the future. Conclusions: To achieve successful intersectoral partnership in school health programs, appropriate partnership guideline for Korean society, policy support, active participation and improvement of consciousness in community stakeholders are needed.

Since users can experience new type of experiment system using augmentation technology and its data visibility, it is a media that is suited to educational purpose application. This paper developed an augmentation-based experimentation that excludes risks and ehnances immersion in chemical experiment. This virtual chemistry experiment system utilizes users' hands to control 3D objects in experiment through interface that interacts virtual objects without markers that are the cause of losing immersion in existing augmentation system. To maximize immersion effect, we propose a virtual chemistry experiment system that enables collaborative work.

The Grid'[1] means the collaboration of computing and experimental resources in dispersed organizations by high-speed network. It has been paid much attention for an unlimited number of potential resources available and the easiness to build collaborative environments among multiple disciplines. However, the difficulty in establishing the environments and accessing and utilizing the resources has prevented application scientists from conducting Grid computing. Thus, the present study focuses on building PSE(Problem Solving Environment) which assists application researchers to easily access and utilize the Grid. The Cactus toolkit, originally developed by astrophysicists, is used as a base frame for Grid PSE. Some modules are newly developed and modified for CFD(Computational Fluid Dynamics) analysis. Simultaneously, a web portal, Grid-One portal, is built for remote monitoring/control and job migration. Cactus frame through the web portal service has been applied to various CFD problems, demonstrating that the developed PSE is valuable for large-scaled applications on the Grid.
