Despite the fact that the copyright has grown into a large-scale business, there are many constant problems especially in image copyright. In this study, we propose an automatic object extraction and classification system for the scanned educational book image by combining document image processing and intelligent information technology like deep learning. First, the proposed technology removes noise component and then performs a visual attention assessment-based region separation. Then we carry out grouping operation based on extracted block areas and categorize each block as a picture or a character area. Finally, the caption area is extracted by searching around the classified picture area. As a result of the performance evaluation, it can be seen an average accuracy of 83% in the extraction of the image and caption area. For only image region detection, up-to 97% of accuracy is verified.

One of the computer application fields which started showing noticeable new growth trends in recent years is the real time communication distributed computing application field. Object-oriented(OO) real time(RT) distributed computing is a form of real-time distributed computing realized with a distributed computer system structured in the form of an object network. In this paper, we describes the application environment as the patient monitor telemedicine system with TMO structure. Vital sign information web viewer systems is also the standard protocol for medical image and transfer. In order to embrace new technologies as telemedicine service, it is important to develope the standard protocol between different systems in the hospital, as well as the communication with external hospital systems. We implemented integration patient monitor telemedicine system between vital sign web viewer systems and hospital information systems.

In this study, we developed a PC - based motorcycle simulator based on the development technology of the virtual patrol motorcycle training system. In order to get the impression that the motorcycle simulator is operating in a realistic way, it is important to have a reliable signal transmission and operation feeling between the driver and the simulator. In order to achieve this, we developed a system that can apply the sub-systems of the actual vehicle to the motorcycle simulator in order to generate the same operation feeling as the actual vehicle. Based on these results, We have developed a method for generating a feedback queue. Vehicle dynamics simulates real-time vehicle motion by receiving input from a steering wheel, accelerating / decelerating pedal, etc. operated by a driver on a vehicle simulator and transmitting the result to a visual and acoustic system, It is the central element of the simulator to generate. I want to summarize the main requirements of simulation dynamics.

This study was conducted to compare the concentration of various air contaminants in nine different laboratories during routine activities. Volatile organic compounds (VOC) were sampled and analyzed using NIOSH Method 1500 and asbestos fibers were sampled and analyzed using NIOSH Method 9002 and 7400. Detectable levels of acetone, toluene and ethanol were found in all the laboratories and xylene and n-hexane were detected in eight of the nine laboratories. All the VOC concentrations were well below the Korean Ministry of Labor's Exposure Limit and American Conference of Governmental Industrial Hygienists' (ACGIH) Threshold Limit Values (TLVs). Total VOC concentrations at the university laboratories were significantly higher than those at governmental agency laboratories. Airborne fiber concentrations were below 0.01 fibers/cc, while the concentration of chrysotile was 2% in insulation materials sprayed on the ceiling of one laboratory. While all the governmental agency laboratories (n=4) had fume hoods, two out of the five university laboratories did not have fume hoods. The capture velocity of half of the fume hoods were below the maintenance standard(0.4 m/sec). In conclusion, the study suggests that the current controls in place at both university and government agency laboratories are not sufficient in limiting exposure to harmful chemicals to non-detectable levels, though they appear to be adequate in protecting workers to levels below applicable occupational exposure limits. The study also suggests that researchers working in university laboratories may be exposed to greater levels of contaminant than those working in government agency laboratories.

Objectives : We examined the effects of electroacupuncture on the cholecystokinin-octapeptide-induced acute pancreatitis in rats. Methods : Rats were administered with $75{\mu}g/kg$ cholecystokinin-octapeptide subcutaneously three times (1, 3 and 5h after shaving) for 5days. Three days after finishing cholecystokinin-octapeptide administration, high frequency electroacupuncture (100Hz) and low frequency electroacupuncture (2Hz) were applied to acupoint equivalent to ST36 (Zusanli) for 7 days. The author determined the pancreatic weight/body weight ratio, the levels of pancreatic heat shock protein HSP60 and HSP72. The author also assay the secretion of ${\beta}-amylase$, lipase and pro-inflammatory cytokines in serum. Repeated cholecysokinin-octapeptide treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : Eelectroacupuncture significantly decreased the pancreatic weight/body weight ratio in cholecystokinin-octapeptide-induced acute pancreatitis, increased the pancreatic levels of HSP60 and HSP72, and decreased ${\beta}-amylase$ and lipase levels in cholecystokinin-octapeptide-induced acute pancreatitis. Additionally, the secretion of $Interleukin-1{\beta}$ and tumor necrosis $factor-{\alpha}$ was decreased in the animals treated with electroacupuncture. Conclusion : These results suggest that electroacupuncture may have protective effects against cholecystokinin-octapeptide-induced acute pancreatitis.

Purpose: The aim of this study was to testify whether clinical performance examination (CPX) was useful to evaluate comprehensive performance for nursing students just prior to graduation. Method: A cross-sectional descriptive study was designed to examine the usefulness. A total of 61 nursing students whose requirement credits were completed for graduation from a C University in G-city, at December, 5, 2007. Data were analyzed by Pearson's Correlation Coefficient and Spearman's rank Correlation Coefficient. Results: This study showed that both of the finals scores with paper and pens and the clinical practicum scores were not correlated with the CPX scores (r=-.031, p=.811; r=.028, p=.831). Consistency of scores between faculties and standardized patients was moderate (r=.752, p=.000). Conclusion: CPX was considered as a different and innovative evaluation from previous testing systems to test the various aspects of performance including knowledge, skill and attitude. Therefore, CPX under high raters' consistency was useful to test nursing students's final performance. Further study would be needed to develop the standard of CPX system.

The following results were abtained based on the research of the occlusal patterns among 1074 handicapped persons (cerebral palsy: 46, mental subnormality: 619, deafmute: 285, blind: 111, childish autism:8, cleft lip and cleft palate:3, polimyelitis:2) of the age between 6 and 23 in Chollanamdo, Korea, in comparison with a normal group of 1048 children of the age between 6 and 15 selected at random in J primary school in Gwang-ju City. 1. According to Angle's malocclusion classification, all the handicapped groups, except the cerebral palsy and the blind, showed a higher prevalence of malocclusion than that of the normal. Especially the prevalence of Class II, devision 1 malocclusion in the cerebral palsy was the highest, and the prevalence of Class III malocclusion in all the handicapped groups was higher than that of the normal group. Among these groups the highest prevalence of Class III malocclusion was in the Down's syndrome group. 2. On the the abnormal pattern of the anterior region, there was no significant difference $(P\leqq0.05)$ between the normal and the cerebral palsy, the deafmute, and e blind. The open bite $(7.27{\pm}1.04\%)$ and the cross-bite $(32.7{\pm}6.33\%)$ of the Down's syndrome wire higher than that of the normal, and the forward position of the mandible could be recognized in the Down's syndrome group. 3. On the midline position of the dentition, all the handicapped showed the same percentage of deviation, but the degree of mandibular shift to the right $(20.00{\pm}5.39\%)$ or left $(10.91{\pm}4.20\%)$ was higher than that of the normal only in the Down's syndrome group. 4. On the abnormal pattern of the posterior region, the cross-bite of the Down's syndrome was higher than that of the normal by $20.00{\pm}5.39\%$, the cross-bite of the cerebral palsy and the cross-bite and the open bite of the mental subnormality were slightly higher than that of the normal. The other handicapped groups showed no significant difference $(P\leq0.05)$ to the normal.

This study was conducted as a survey to find out middle-aged persons's housing preferences for a future elderly housing and to grasp background characteristics of persons influencing the preferences and the effect of elderly's aging situations on the changes of their preferences. A sample of 300 middle-aged people was selected purposely from parents of university students living in Gwang-ju city. Questionnaires were administered to parents by students and analysed with SPSS Windows 10 program. Middle-aged persons's housing preferences were differed according to elderly's aging situations, in the case of healthy situation, they tended to prefer to stay present house without their children in irrespective to couple or single, whereas in the case of unhealthy situation, they tended to prefer to live with their children. and couples showed preferences for planned housing for the elderly and singles showed preferences for elderly housing facilities with care services. The most important characteristics of elderly housing among middle-aged people was a places where they can enjoy leisure and provide home-help services, located in the suburbs. Also middle-aged persons were likely to prefer to a green spaces such as garden, path for walking, and madang for the elderly housing. Needs for community care services (NCCS) were required above the average. Among the items of NCCS, a visiting medical examination was the most demanding, and a visiting nursing services, a emergency calling bell, and home repairs were sequently followed in the level of needs. The characteristics of the elderly housing which preferred to and needs for community care services were influenced by middle-aged persons's age, gender, subjective evaluation of economic abilities, tenure status, the cost of living, and the size of housing. This findings suggests that it must to be considered to develop various types of the elderly housing depending on socioeconomic status.
