  • This paper presents the design technique and the performance evaluation of RPC(remote procedure call) algorithm using queue on the micro computer, works tationand PC's underUNIX SystemV, The existingRPC algorithmis aftercalling remote Procedure, it must has be returned in order torun next instructions. But if it is not done so, it must wait indefinitely. To solve this problem, a message transfer method which used queue is adopted. And the improved RPC algorithm that can process in sequence is designed and implemented.

  • In this paper, a study on the performance evaluation of a cycloid reducer for remote weapons systems is presented. Reduction gears applied to remote weapons vehicles need to be compact and capable of large torque transmissions as well as require structural optimization, high load capacity, and high precision position control. To meet these requirements, a cycloid reducer with low backlash, high precision, high overload capability, high rigidity, and high efficiency is required. Thus, a cycloid reducer with a reduction ratio of 127:1, backlash of 1 arcmin (1/60 deg) or less, and reduction gear efficiency of 70% or more, which are the design requirements for a remote weapons system, was designed utilizing a design and analysis program (HEXAGON) for gear engineering. To confirm the performance of the cycloid reducer, the hardness of the main components of the manufactured cycloid reducer, reduction ratio, and efficiency were measured.

  • In the ubiquitous computing environment, a ubiquitous vehicle will be a communication node in the vehicular network as well as the means of ground transportation. It will make humans and vehicles seamlessly and remotely connected. Especially, one of the prominent services in the ubiquitous vehicle is the vehicle remote operation. However, mutual-collaboration with the in-vehicle communication network, the vehicle-to-vehicle communication network and the vehicle-to-roadside communication network is required to provide vehicle remote operation services. In this paper, an Internet-based human-vehicle interfaces and a network architecture is presented to provide remote vehicle control and diagnosis services. The performance of the proposed system is evaluated through a design and implementation in terms of the round trip time taken to get a vehicle remote operation service.

The Comparison of Effectiveness between Near Acupuncture Point Needling and Remote Acupuncture Point Needling on Treating Ankle Sprain of Acute Stage (급성기 족관절 염좌의 근위취혈(近位取穴)과 원위취혈(遠位取穴)의 치료 효과 비교 연구)

  • Objective : The purpose of this study is to compare the effects of near acupuncture point needling and remote acupuncture point needling on treating ankle sprain of acute stage. Methods : From March 1st, 2007 to May 30th, 2007, the 50 patients who had visited Iksan oriental medical hospital, Wonkwang university with acute ankle sprain were divided into 2 groups ; one group took near acupunture point needling, and the other group took remote acupunture point needling. Both group had been treated with the same additional rest, ice, compression and elevation(RICE) therapy. To evaluating the efficiency of each treatment, Visual Analog Scale(VAS) and Ankle-Hindfoot Scale(AHS) were applied before 1st treatment and after 3rd treatment. Results : As a result of evaluation by using AHS, the score change comparison between the two groups had no significance after the treatment. As a result of evaluation by using VAS, treatment score of remote acupucture point needling was marked lower than score of near acupucture point needling. Conclusion : Remote acupucture point needling is more effective than near acupucture point needling in controlling the pain of acute ankle sprain.

  • We developed a package of remote phosphor structure having blue LED chips and phosphors physically separated, and the characteristics were evaluated according to different classifications of phosphor coatings. Remote phosphor was produced by screen printing coating on glass substrate with phosphor content rated paste and heat treatment. After mounting Remote phosphor, which has been classified according to number of coatings, on top of blue LED chips, luminous flux, luminous efficacy, CCT and CRI were measured. The measurement results showed the most suitable characteristics of white LED package as a general light source when the content rate of phosphor in Remote phosphor was 80 wt.% with 3 layers of coatings and thickness over $12{\mu}m$.

  • In the study, the feasibility of landscape ecological measures as indices system for interpretation and evaluation of regional ecosystem was investigated through the application to Yongin City. Each patch metrics well showed the class structure and supplemented the class metrics, and class metrics also showed well the landscape structure and supplemented the landscape metrics. And the change analysis through subtraction of two set of landscape ecological measurement in two point of time showed the dynamic trends very well. One of the dynamic trends in Yongin City was the rapid fragmentation. While there was no landcover data on Yongin City, using Landsat data and remote sensing techniques were proved to be efficient and effective to produce the digital landcover data.

  • The intracranial hemorrhage in regions remote from the site of initial operations is unusual but may present as fatal surgical complication. We report a rare case of multiple, sequential, remote intracranial hematomas after cranioplasty in a patient who did not have any prior risk factors. A 51-years-old man was transferred to the hospital after a head trauma. The brain computed tomography (CT) revealed acute subdural hemorrhage on the right hemisphere with prominent midline shifting. After performing decompressive craniectomy and hematoma removal, the patient recovered without any complications. However, the patient showed neurological deterioration immediately after cranioplasty, which was done three months after the first surgery. There was extensive hemorrhage in the posterior fossa remote from the site of the initial operation site. The brain CT taken soon after removing this hematoma evacuation displayed large epidural hematoma on the left hemisphere. This case represents posterior fossa hemorrhage after supratentorial procedure and sequential delayed hematoma on the contralateral supratentorial region thus seems very rare surgical complications. Despite several possible pathogenetic mechanisms for such remote hematomas, there are usually no clear cut relationships with each case as in our patient. However, for the successful outcome, prompt evaluation and intensive management seem mandatory.
