  • The advance of computer, network, and Internet technology enables the control systems to process the massive data in the distributed computing environments. To implement and maintain the software in distributed environment, the component-based methodology is widely used. This paper proposes the middleware architecture for the distributed computer control system. With the proposed middleware services, it is relatively easy to maintain compatibility between products and to implement a portable control application. To achieve the compatibility between heterogeneous systems, the proposed architecture provides the communication protocols based on the XML with lightweight event-based service.

  • This study investigate the balance and biochemical status of riboflavin in Korean men. During the experimental period, four riboflavin diets with different levels of riboflavin(0.4, 0.6,0.8 and 1.0mg/1000kcal) were followed by eight healthy college men. the riboflavin status was assayed by erythrocyte glutathine reudcctase activity coefficient (EGRAC0 and urinary excretion of riboflavin. Riboflavin intake of the subjects who consumed a det was 0.46mg/1000kcal. the riboflavin intakes of the subjects who consumed the experimental diet with 0.4, 0.6, 0.8 and 1,0mg/1000kcal of riboflavin were 0.41, 0.60, 0.81 , 0.97mg, respectively. Fecal riboflavin loss, absorbed riboflavin , urinary riboflavin loss and retained riboflavin increased in the subjects consumed 0.4, 0.6, 0.8 and 1.0mg/1000kcal of riboflavin. The average EGRAC values for the subjects consumed 0.4, 0.6, 0.8 and 1.0mg/1000kcal of riboflavin were 1.303$\pm$0.029, 1.271$\pm$0.022, 1.239$\pm$0.013, 1.202$\pm$0.030, respectively and urinary riboflavin values ($\mu\textrm{g}$/g creatinine) were 86.89$\pm$ 20.07, 123.88$\pm$ 15.88, 240.70$\pm$57.14 and 393.36$\pm$76.94, respectively. Results indicate that 0.6mg/1000kcal is the level of riboflavin intake needed to maintain urinary riboflavin within the normal range. And above1.0mg/1000kcal of riboflavin is need to maintain urinary riboflavin with in the normal range. And above 1.0mg/1000 of riboflavin is needed to maintain the EGRAC within the normal range. The riboflavin intake correlated positively with urinary riboflavin value, but correlated negatively with the EGRAC value. The EGRAC value correlated negatively to protein intake as well as animal protein intake. The linear equation of between riboflavin intake and EGRAc was EGRA=-0.1667 $\times$riboflavin intake +1.3710. The riboflavin intake to maintain EGRAc below 1.20 was calculated 1.02mg/1000kcal by the above equation.

  • For the National Geo-Spatial Information System the development of the National Digital Basemap database is actively underway in Korea. For the National Digital Basemap database to be truly useful for various applications development it is essential to maintain its reliability. To maintain the reliability of the database it is necessary to understand the nature and the frequency of the errors in it. In general, a data inspection under the standardized quality control process is required to maintain the quality of a large database. In addition, it is important to maintain complete and detailed records of the inspection results so as to understand the relationship between the m and other factors causing errors. These records can be used as a reference for map updates and future application development. The goal of this study is to count the frequency of errors based on the typology of errors found in the digitized map inspection process and to analyze the correlation between errors and topographic composite quotient This study also provides guidelines for the inspection process regarding the error-prone cartographic elements in the digital map generation process.

  • The purpose of this study was to identify the needs which were perceived by patients who were received spinal anesthesia for surgery. The subjects consisted of 50 adult patients who were admitted to 2 university hospitals and 2 general hospitals in Pusan city and 1 general hospital in Koje City for surgery under spinal anesthesia. Thirty eight percent of subjects received information about anesthesia before the operation. The instrument for this study was developed by the researcher based on literature and a pretest. Data were collected from December 10, 1999 to February 10, 2000 and were analyzed by content analysis. The results were that there were 533 meaningful statements in the needs of spinal anesthesia patients. The needs of spinal anesthesia patients had 51 items (preoperation (6), induction of anesthesia(5), intraoperation (27), postoperation(13)) and 6 categories (information, emotional welfare, physical welfare, post anesthetic management, control of physical environment, humane treatment). From the results, it can be concluded that: 1. In the pre-operation period, we have to explain anesthesia procedures, adequate position of anesthesia, duration before anesthesia wears off and sensation of paralysis. We have to supply emotional support to relieve anxiety because of anesthesia. 2. In induction of anesthesia, we have to support patient's position for anesthesia, and relieve anxiety so that patients participate in induction of anesthesia well. 3. In intra-operative period, we have to check the level of anesthesia, and keep up a comfortable position for operation and care for physical discomfort such as thirst, nausea, vomiting, dyspnea and to maintain body temperature of the patient. Since the patient is conscious, we have to communicate with the patient to relieve anxiety, maintain privacy, inform the patient of the process of the operation and encourage the surgeon to explain the outcome of the operation. The operating team needs the careful about what they say and to place the instrument well. We have to ventilate the room air and reduce noise. 4. In the post-operative period, we have to explain the purpose and duration of bed rest, complications of anesthesia and care for physical discomfort such as pain, dysuria, headache, backache. Also we have to maintain body temperature of the patient and maintain privacy.

  • The purpose of this study was to compare the world class women's hurdlers with kinematic variables Lee Yeon-Kyoung's in the 100m hurdle. Among korea elite female hurdler, Lee Yeon-Kyoung was participated as a subject. Eight JVC video cameras(GR-HD1KR) were used to film the performance of Lee Yeon-Kyoung at a frame rate of 60fields/s. The real-life three-dimensional coordinate data of digitized body landmarks were smoothed using a fourth order Butterworth low pass recursive digital filter with an estimated optimum cutoff frequency of 7.4Hz. After analyzing and comparing Lee Yeon Kyung's kinematic variables with the world top class hurdlers in the woman's 100m hurdle run, the following conclusions were obtained. 1. Lee should be able to increase the speed with over 5.4m/s from start to first hurdle and then maintain the speed range from 8.33m/s to 8.67m/s until 10th hurdle. Lee should have to maintain the speed with 8.51m/s from 10th hurdle to finish line. 2. Lee has to reach her maximum running speed at 5th hurdle and then has to shorten running time with 0.5sec between hurdles. 3. Lee should be able to run around 2.5sec from start to frist hurdle and then maintain under 1.00sec following phases. Lee should be able to maintain under 1.10sec from 10th hurdle to finish line. 4. Lee needs to control a consistent takeoff and landing distance pattern, Lee needs to lower the height of the center of gravity of the body with 0.33m when she clears the hurdles.

  • Background: Recently, measure of heart rate variability and the nonlinear "complexity" of heart rate dynamics have been used as indicators of cardiovascular health. Several investigators have demonstrated that heart rate variability decreased in aging, congestive heart failure and coronary heart disease. Because hypertensive patients showed alternation of cardiovascular homeostasis, we designed this study to evaluate the effect of anesthesia in hypertensive patients with approximate entropy (ApEn). Methods: With informed consent, eighteen normotensive patients and eighteen hypertensive patients were given no premedication. ECG data were collected from 10 minutes before induction to 15 minutes after induction. Collected ECG data were stored into computer binary files. We calculated ApEn from the collected ECG data. Results: Before induction, ApEn of hypertensive patients was significantly lower than normotensive patients(p<0.05). During induction and maintain of anesthesia, there was no difference of ApEn between two groups. During induction and maintain of anesthesia, in normotensive group, ApEn was significantly lower than that of preinduction(p<0.05). And ApEn during maintain of anesthesia was lower than that of induction(p<0.05). During maintain of anesthesia, in hypertensive group, ApEn was significantly lower than that of preinduction(p<0.05). Conclusions: Before induction, ApTn of hypertensive patients is significantly lower than normotensive patients. As anesthesia was deepened, ApEn of two groups were decreased. Because the baroreflex of hypertensive patients is already decreased, decreasing of ApEn of hypertensive patients during anesthesia is less than that of normotnesive patients.
