A quadruped monitoring robot is introduced. The robot has several features that poses arbitrary position thanks to a 4-wheel hive mechanism, transmits an image and command data via RF wireless communication, and moreover, the imaged date are transferred through a network communication. The robot plays a role in monitoring what is happening around the robot and covers wide range due to a moving camera operated by the 4-wheel mechanism. The robot system can be applied k versatile models based the distinguished techniques introduced in this paper

Many pumping station of Maehang-ri of Hwasung city are established for irrigation water supply, and brine permeation phenomenon is happening thereby. Proposed optimum pumping fluid amount conclusion model that use tidal efficiency and Ghyben-Hertzberg theory so that brine does not permeate in pumping station hereupon and applied this in study area.

This study tries to analyze the possibility of application of project financing to electricity industry and analyze the management of risks happening in the process of foreign project procurement and construction. Those are based on the trends and analysis of project financing in foreign projects. Risks are 'classified as risks before completion of projects and risks after completion. Project financing is key element of exportation and financial strategies and activation of project financing may provide the acceleration of the efficient financial market.

Domestic freight car holding amount is possessing much amount than other vehicle model about 14,000. Problem is happening in bogie device of cast steel structure because is structure that there are many wear departments. Therefore, the KNR is restricting running speed of empty car by 70km/h low. In this research, presented speed elevation way as dynamic characteristic analysis result that use ADAMS and confirm running safety by main line test.

There are a lot of troubles during the transfer of the source of electric power in UPS (uninterruptible power supply system) which is indispensable to the industrial equipments. They cause blackout accidents, resulting in a great economic loss. After measuring and analyzing the transient phenomena happening during the transfer, this paper presents the solution of the troubles. The solution can be used as a basic material for maintenance and it can minimize the troubles occurring in UPS and enhance the reliability of it.

With flourishing of new facilities, we are now set to expand the horizon of the human knowledge of the universe deep into the very beginning of the cosmic history of astronomical objects. In such an endeavor, extreme objects and cosmic events such as violent cosmic explosions, rapidly growing supermassive black holes, and proto-clusters of galaxies, are the objects to be investigated in order to unveil what was happening in the very early universe. We will discuss what we have learned and are expecting to discover from such extreme objects about the infant universe both currently and in future, highlighting some of our recent works.

It was a special phenomenon in the art of 20th century that the earnest engagement of spectators came up to the surface in the area of artwork-creation and art-experience which had been one-sided processes for a long time. Such a genre of Optical art or Kinetic art, had pulled out active engagements of audiences in enjoying diverse works, played the role of locomotive in the Interactive Art. Of course, many kind of art made an appearance on the channels of diverse media from that times. For example, many people came to enjoy taking part in such a genre as Happening formated the mode of face-to-face communication between the creator and the spectator. The appearance of the technology of digital media had a decisive influence on the area of the Interactive Art. From that time on, people have come to accept the reciprocity of the relations between artist and spectator naturally. This paper makes researches on some trends in the development of Interactive Arts by way of analyzing some representative Interactive Artworks typing the birth and growth of Interactive Art.

As we enter an era of emotional and endlessly competitive society, there has been a lot of changes happening to the styles and images of men, traditionally associated with strength and power. Today, the media is giving information on today's trendy men's styles and images to meet the growing demand by consumers, and giving appropriate gains in the process to all - both information providers and consumers. Generally speaking, the cover of a magazine represents the concept and image of the magazine. The cover model is closely tied with the symbolic image of the magazine, the current times, and what the general public wants. Therefore, research on the cover models of a lifestyle magazine has significance in that the current style trends will be able to be understood directly. The present research investigated the sexual images of men's magazine cover models. In carrying out the research, the sexual images were classified into the following: homosexual, cross sexual, metro sexual, and uber sexual. The research findings showed that uber sexual is the dominant sexual image in men's magazines in Korea, followed by metro sexual. In conclusion, the findings suggest an expansion of the traditional image of men, happening with the changes in traditional sex roles.

Pre-production has become one of the more noticeable new trends in the Korean drama industry. The trend is being led both by the outsourcing producers and the incumbent broadcasting companies. In particular, the broadcasting companies seem to favor the mode of pre-production more and more, and that is happening not only when they are working on their own but also when collaborating with outsourcing producers. It has been generally proven and believed that the recruitment of A-list production factors is one sure way to produce better commercial results in the Korean drama industry. Then, the recent phenomenon of the pre-production is happening with the lack of the of A-list factors' participation. Especially, A-list writers have been showing a high degree of reluctance to take part in the pre-production, mentioning the inability to reflect the audience's responses on their stories. While the pre-prodction is being adopted in various genres, it is observed that the pre-produced dramas with multi-genre features have a higher chance to succeed.

The purpose of this study is grasp the problem of the gymnast, Kim, Dong-Hwa's Kip to Swallow Motion in Rings, and make up for the weak points to help him to perform a better performance. Therefore, two tryouts for $28^{th}$ Athens Olympic Games were filmed using video camera then finalized with Kinematical Analysis using 3D motion analysis program followings are the form of conclusions. 1. In the very first tryout, when he was doing a Swallow Support Scale, his CM position was high and arm slope was deduction because when he was doing Kip, the ascent velocity was low and he tried excessively to pull him on rings due to relying upon angular movement of shoulder joint. 2. When he was doing drop, he let his hip angle bend only little bit and let fall so making shoulder angle wider and maintain the level horizontally occurs strong drop motion when vertical descent is happening. 3. As a result, lowering the direction of a kick makes CM's movement path lower, increase vertical ascent velocity, and it helps to do the Swallow Support motion in short period of time. 4. After a strong drop motion, which is deep and fast, would make rope of ring shake so there is a defect that the body moves to forward area. However, it does not effect in Swallow Support Scale motion. 5. In the second tryout, trunk rotation angle and arm slope was fixed decrease while doing rotary motion. When rotary motion was happening, before the body was going under the rings, maintained his arm slope horizontally so his Swallow Support Scale motion was nearly perfect.
