  • Due to recent improvements in computer processing speed and image processing technology, researches are being actively carried out to combine information from a camera with existing GNSS (Global Navigation Satellite System) and dead reckoning. In this study, the mathematical model based on SPR (Single Photo Resection) is derived for image-based assistant algorithm for vehicle positioning. Simulation test is performed to analyze factors affecting SPR. In addition, GNSS/on-board vehicle sensor/image based positioning algorithm is developed by combining image-based positioning algorithm with existing positioning algorithm. The performance of the integrated algorithm is evaluated by the actual driving test and landmark's position data, which is required to perform SPR, based on simulation. The precision of the horizontal position error is 1.79m in the case of the existing positioning algorithm, and that of the integrated positioning algorithm is 0.12m at the points where SPR is performed. In future research, it is necessary to develop an optimized algorithm based on the actual landmark's position data.

  • The representative study of Patellofemoral Joint Merchant method can show the view for inspection of the sulcus angle, congruence angle and diagnose whether there are the vertical fractures and recognize the degree of dislocation and patella subluxation. However, anatomical correlation about the degree of knee joint curvature changes during position adjustment and distortion of the image reduces reproducibility. In order to resolve these problems, Merchant method needs to use assisting device which reduces the occurrence of repeat projection and effectively to increase unification of examination and the consistency of the image. However, there are disadvantages for patients who take other examinations. For example, they have to change the position for every examination and it might cause the patient's discomfort and increase of examination time. In this study, we newly devised commercial assisting device which improves the reproducibility of the images and reduces inconvenience of patients movement. Further research should be taken to obtain a image without patient's movement and to reduce the time of the examination than existing method.

  • The library means to children a place where they find information necessary for them among a variety of knowledge and information to address their intellectual curiosity, which makes their lives wise and mature. There are not enough research materials understanding children's cognitive systems and behaviors in studies of a children's library with this necessity. This study divided and analyzed the behaviors of children, who were users into three types of reading in terms of information processing. First, it observed the types of reading depending on the stage of their cognitive development; Second, it analyzed the patterns of their behaviors through plays; and lastly, it presented the phases of their behaviors depending on the degree of an assistant's intervention. As a result of the study, the sensory system used and the space preferred differed depending on the stage of their cognition; there were differences in the patterns of their behaviors in each age group depending on the type of play; and there were differences in the children's ability of information processing depending on the assistant's ability. It is anticipated that there will be improvements of children's reading ability at the reading room in a better environment if the three types are considered in terms of information processing.

  • The water conditioning experiments of brown rice were performed to analyze the variation of the milled rice recovery using a continuous type conditioner at Jin-ju, Yeo-ju, and Yong-in RPC(Rice Processing Complex). About 8,000 kgf, 6,000 kgf and 10,000 kgf of the brown rice of 13-14 %(wb) initial moisture contents were used as experimental materials at Jin-ju, Yeo-ju, and Yong-in respectively. The broken rice and rice bran were collected and weighted to calculate the milled rice recovery. The amounts of broken rice with water conditioned occurred lower than that of broken rice without water conditioned. And the milled rice recovery of water conditioned ones were increased as 1.22%, 0.87%, and 1.00% compared with those of the non water conditioned ones at Jin-ju, Yeo-ju. and Yong-in respectively. Especially, the result of the experiments of Jin-ju RPC showed that about 33% and 35% of total increased milled rice recovery were the portion of the moisture content increment and the broken rice reduction respectively.

  • Background: Fluoroscopy has been an integral part of modern interventional pain management. Yet fluoroscopy can be associated with risks for the patients and clinicians unless it is managed with appropriate understanding, skill and vigilance. Therefore, this study was designed to determine the amount of radiation received by a primary operator and an assistant during interventional pain procedures that involve the use of fluoroscopy. Methods: In order to examine the amount of radiation, the physicians were monitored by having them wear three thermoluminescent badges during each single procedure, with one under a lead apron, one under the apron collar and one on the leg during each single procedure. The data obtained from each thermoluminescent badge was reviewed from September 2008 to November 2008 and the annual radiation exposure was subsequently calculated. Results: A total of 505 interventional procedures were performed with C-arm fluoroscopy during three months. The results of this study revealed that the annual radiation exposure was relatively low for both the operator and assistant. Conclusions: With proper precautions, the use of fluoroscopy during interventional pain procedures is a safe practice.

  • The purpose of this study is to analyze the effect of sex of supervisor on the stress and promotion of Korean women workers in the workplace using the Korean Women Manager Panel. The results demonstrate that when the direct boss of female workers was female, stress in the workplace was high and the promotion rate of staff and assistant managers was low. According to the theory of queen bee phenomenon and role congruity theory, a structure of glass ceiling and the male-dominated working culture does not require positive qualities of female leadership but requires a high recognition standard or competitiveness. It can be interpreted that the female worker with the female supervisor showed more stress in the workplace and the probability of female promotion in staff and assistant managers is low.

  • Purpose: The purpose of this study was to perform an operating room nursing activities analysis and estimate nursing intensity of each nursing activity based on the Relative Value Scale (RVS). Methods: The methodology for this study of RVS was based on the work of Hsiao et al. The first stage was to identify nursing activities and the second to measure intensity of nursing activities including technical skill, mental effort, and stress. Results: Calculation of the RVS for 99 nursing practices showed a score range from 300.00 to 1337.78. CS operation assistant, OS operation assistant, and obtaining certification had high nursing intensity. Surgical hand washing, putting on surgical gowns, surgical gloves and surgical caps and mask had low nursing intensity. Conclusion: The activities of operating room are not compensated separately but reimbursement is usually included in physician fees. In the future, an estimation of nursing cost should show the nursing contribution rate to total operation revenue.
