This paper study the way of increasing the credit loan for the Venture Companies. They are very important in national economics. But they are short of financial and mortgage although they have many kinds of superb ideas and technologies. Korean government has tried to financially support them. But the support has had its own limit. Banks and other financial institutions have not been in a positive position to loan money out to venture companies because their businesses are highly risky. The credit evaluation system of medium and small business are need to improve in order to increase the Venture Companies. loan. So, it is necessary to find new measures to activate credit loans to them.

In this study, we propose trajectory-based arrival management using CDO (Continuos Descent Operations). The operational procedures with TBO (Trajectory-Based Operations) concept were established to allow aircraft and ground system to share the trajectories with each other in real time. The proposed operational concept was validated in the air traffic control simulation environment, which consists of controller working position, pseudo pilot system, air traffic generation system, and controllers' decision support system for arrival management using CDO. Simulation results compared with actual flight data indicate that proposed concept could improve the efficiency of traffic flow management in terms of total descending time and fuel consumption. And it was confirmed that if there is a system that can share and utilize the synchronized trajectory, it can be helpful to control arrival aircraft and apply CDO concept.

This study is about the conceptual design steps in cultural knowledge content development. This study proposes the method called situational decomposition Modeling Technique. It is based on the events which are the sum of related processes. Processes are the sum of related actions. This event has a position in specific time and space, and each event has objects. Users can search events using objects and find any processes or actions one desires.

Immersed tunnel had been a rather new term in Korea before Busan-Geoje fixed link project was started and became known through the media. Although Korean is unfamiliar with the immersed tunnel, this construction method has a long history in the world. Busan-Geoje Fixed Link immersed tunnel consist of 18 elements and each element is approximately 180m long. These tunnel elements are prefabricated of reinforced concrete in a temporary dry dock and are towed to the site and lowered into final position in a dredged trench and are placed on a screeded gravel bed directly without temporary support.

In this paper we describe a road following method for an autonomous vehicle. From a road image in gray level, a road boundary is detected using a gradient operator, and then the road boundary is converted to orthogonal view of the road showing the vehicle position and heading direction. In this research an efficient road boundary search technique is developed to support real time vehicle control. Also, an obstacle detection method, using images taken from two different positions, has been developed.

It is our common understanding that biological materials like microorganisms, tissue and cell cultures, seeds, plants and animals are inevitable resources for the development of science and technology. Culture collections which are reservior of biological materials now occupy a central position in life sciences and biotechnology. The World Data Center of Microorganisms (WDC) is a infrastructure of culture collections in the world realizing quick and smooth exchanges of information and microorganisms to support research and development in those fields. The WDC was relocated from University of Queensland in Australia to out institute RIKEN in 1986. This article introduces a function for WDC in RIKEN (RIKAGAKU-KENKYUUSHO, the Institute of Physical and Chemical Research)

To support cooperative work in various scenes by computer systems, functions of sharing personalization, observation and control are needed. Especially, in advanced cooperative work, people have various position so that sometimes one person needs to restrict behavior of another. In this paper, we describe representation of access restriction of hypermedia system, which is framework of CSCW(Computer-Supported Cooperative Works) system we developed and propose a way to go on working cooperatively with people, restricting others.

In this paper, a $10{\times}10$ micro SLM array for phase and amplitude modulation of incident light is designed and fabricated using surface micromachining technology. Hidden spring structure is used in order to maximize the fill-factor and minimize diffraction effect at the support posts. Static and dynamic characteristics of designed micro SLM are simulated with ABAQUS and measured with optical measurement system using He-Ne laser and PSD(position sensitive devise).

This paper describes the design and fabrication of an automatic alignment and loading system for workpieces. To move a workpiece to a chucking position of a machine tool using a gantry robot, an automatic aligning device is required to load the workpiece before machining and automatically align them. The automatic alignment system was conceptually designed, and the structural analysis was performed for the main parts such as the top plate, center support, front and back support, and support shaft. Based on the structural analysis results, the size of these structures was determined. The automatic alignment system was manufactured, and the vertical movement characteristics of the workpiece up-and-down movement device and the rotation characteristics of the workpiece rotation device were experimentally examined. The result has confirmed that they operate normally.
