본 논문에서는 개발된 편광방식 스테레오 모니터링(KAERI-PSM) 시스템의 성능을 평가하기 위해 6 D.O.F의 퓨마 로보트를 이용한 원격조작 실험을 수행하였다. 카메라의 관측각도를 달리하는 3가지 원격조작실험은 6명의 실험자가 힘반향 조이스틱을 사용하여 로보트 암을 (1) 직접 (2) 일반 모니터 (3) 동기방식 스테레오 영상 모니터 및 (4) 개발된 편광방식 스테레오 영상 모니터를 통하여 보면서 6가지의 조합된 방법으로 총 36번 수행하여 걸린 평균 시간과 평균 에러 발생 수를 비교하는 것이다. 실험 결과 스테레오 영상 모니터를 사용한 원격작업은 일반 모니터를 이용했을 때 보다 훨씬 짧은 시간에 정확히 수행할 수 있었으며, 물체 이동에 대한 카메라의 각도가 실험의 주요한 변수가 됨을 알 수 있었다. 또한 동기방식과 편광방식의 비교에서 속도와 정확도 면에서는 두 방식이 비슷했으나 눈의 피로도로 인한 작업의 안정성 측면에서는 편광방식이 우수함을 알 수 있었다.

The Purpose of this study is to look for the total conspectus of Roo-Jong(RJ) Architecture in the middle and latter era of Koryo Dynasty. The method of this study is the review of old literature, the Roo-Jung description of Dong-Mun-Sun, which had compiled in the Ninth year of Seung-Jong (AD 1478) by confucian scholar. The conclusions of this study can be summarized as follows : 1) The main currents of thought having a great influence on the RJ are thought of Mountain God (or Sin Sun, which is dwelling in mountain) or Taoist, thought of Lao-tzu and Chuang-tzu. They had required the RJ Architecture to pursuit the life of God. In this existence value meaning, the RJ Architecturethe is the semi-sacred & profane space. In the being aspect, RJ is the transcendental architecture. 2) The way of life of in the RJ had strongly turned from the personal space, mainly mind control place, into the friendship-society space, pastime place. 3) The RJ had located after the images that is what should be. The images were formed on the ground of natural landscape elements, communication elements. And these elements were indicated on one's visual, auditorial sensation with oneself. 4) In planning aspect, the scope of visual, Pungsu and history were aided with the factors of climate, topography and geography. Specially in location and fabric planning, they had regarded more important the objects and scope of visual than the climate factor.

In early 1990s, huge changes have happened in the socialist societies. There was tremendous pressure on the North Korea to adopt a policy of the openness toward the outside world despite the possible in ability to maintain its political system and succession of power. When the North and South Korea will be re-united, whenever that could be, one of the most important and critical issues would be the land reform in the North Korean. Especially, forest land will be the largest land resource in the Unified Korea. This paper aims to provide the forest land reformation for implementing the restructuring of North Korean land system after reunification. The reformation process of forest land will be consisted of three stages. First, ownership of forest land will be made temporary re-nationalization to prevent a social disorder and carry out public roles of forestry. Second, among re-nationalized land through the first stage, long-term lease system will be adopted to overcome the discrepancy of land markets. Third, the objective forest lands on long-term lease will be privatized in consideration of the tenant`s achievements evaluated by nationalized forest land manager. And, one of critical issues after re-unification will be restored the former land ownership. The restitution of ownership will create various problems such sluggish investment, hinderance to SOC expansion, higher integration costs and protection of current land users. Second, compensation of ownership will be need the huge budget. Therefore, re-privatization or temporary nationalization without restitution and compensation will be a suitable approach in the Korean situations. Because of forest land should be managed for preserving the value of natural environments and the public land use, forest lands for public use will have to maintain the re-nationalized ownership.

굴삭기를 전진과 후진시키는 주행모터에는 주차브레이크(parking brake)가 내장되어있다. 이 주차브레이크는 굴삭기가 주차되었을 때 고정뿐만 아니라 전진 및 후진을 하지 않는 상태로 굴삭작업 할 때에도 차체를 지면에 고정시킨다. 정확한 굴삭작업을 위해서는 작업충격이나 자중을 포함한 굴삭부하가 발생했을 때 차체를 지면에 견고하게 고정해주는 브레이크 기능이 굴삭기가 주차되었을 때의 고정보다 더 중요하고 작용횟수 또한 훨씬 높다. 본 연구에서는 다중 마찰 판(multi friction disc)을 스프링 힘으로 작동(결합)시키고 유압실린더로 해제시키는 굴삭기 주행모터의 주차브레이크에 대해서 작용 압력별로 반복실험을 실시하여 측정된 데이터를 설계 이론값과 비교하여 주차브레이크의 특성을 분석하였다. The parking brake is an essential unit embedded in the track-driving motor of an excavator. The parking brake plays an important role in keeping the excavator in place not only when it is parked, but also during the digging operation. In fact, the load placed on the parking brake during the digging operation is significantly higher than the parking load, because the impact and rating loads caused by the bucket digging force cycle frequently and have very high load ranges. Therefore, the load conditions during the digging operation should be taken into account in the parking brake certification test. In this study, a series of experiments was carried out in which various operating pressures were applied to the parking brake, where repeated loads were reciprocally placed on the brake by locking the multifriction disc and releasing the hydraulic cylinder. The characteristics of the parking brake were investigated by comparing the obtained experimental results and the theoretical design specifications.
