There are a lot of influences, such as location of camera, luminosity, brightness, and direction of light, which affect the performance of 2-dimensional image recognition. This paper suggests an adaptive method for face-image recognition in noisy environments using evolvable filtering and feature extraction which uses one sample image from camera. This suggested method consists of two main parts. One is the environmental-adjustment module which determines optimum sets of filters, filter parameters, and dimensions of features by using "steady state genetic algorithm". The other another part is for face recognition module which performs recognition of face-image using the previous results. In the processing, we used Gabor wavelet for extracting features in the images and k-Nearest Neighbor method for the classification. For testing of the adaptive face recognition method, we tested the adaptive method in the brightness noise, in the impulse noise and in the composite noise and verified that the adaptive method protects face recognition-rate`s rapidly decrease which can be occurred generally in the noisy environments.

According to the construction of infrastructure for the water resource management services, the importance of the eco-friendly reservoir tank management is being spotlighted. In this paper, we proposed the eco-friendly reservoir tank management using prediction for improving the water quality and on-line managing efforts of reservoir tanks. The proposed method defined the context and environment of the reservoir tank and predicted the profited service according to the pump motion, the solar battery, the chemicals, the water level, the telephone line, and the modem using collaborative filtering. To evaluate the performance of the eco-friendly reservoir tank management system using prediction, we conducted sample T-tests so as to verify usefulness. This evaluation found that the difference of satisfaction by service was statistically meaningful, and showed high satisfaction. Accordingly, the satisfaction and the quality of services will be improved the efficient prediction by supporting the context information as well as the environment information.

With the help of computer graphics technologies, the visual effects techniques using these technologies replaced most of special effects techniques which had been used for early films. For these changes, directors and visual effects creators make an effect in a scene through their mutual agreement in contemporary films. However, they undergo a lot of trial-and-error while making a visual effects scene because they cannot perfectly communicate their ideas due to the director`s narrative language, and also because of the visual effect creator`s language of computer graphics technology. This research suggests the design of a visual effects data retrieval system for efficient communication between directors and visual effects creators. This application provides the means to search a database analyzing visual effects scenes extracted from 14 remarkable movies in visual effect history by narrative and visual effects technique. They can search visual effects scenes using this application. also, this data can foster communication with directors and creators so they can make an efficient production pipeline.

Today`s Digital Environment made Typography to enter into a new phase. The Type which is a principal component of Typography is no exception to this aspect. However since the existing two-dimensional space has figurative potential, Visual Communication designers are still striving to explore both X axis and Y axis. In this context, Z axis which signifies `Depth` is often recognized as an unfamiliar mathematical concept unrelated to Design Sensibility. If Z axis is used, the figurative aspect can be acquired, which was hard to be realized in the flat space, because the additional space of depth allows the expansion of omni-directional expression of target. Most notable is the fact that Z axis provided by Digital Environment has actually long existed and is inseparable from Type. This study, therefore, focuses on the three-dimensional expression of Type in the Visual Communication Design area by taking into account the above characteristics.

In this paper, we propose user-centric immersible and interactive electronic book based on the interface of tabletop display. Electronic book is usually used for users that want to read the text book with multimedia contents like video, audio, animation and etc. It is based on tabletop display platform then the conventional input device like keyboard and mouse is not essentially needed. Users can interact with the contents based on the gestures defined for the interface of tabletop display using hand finger touches then it gives superior and effective interface for users to use the electronic book interestingly. This interface supports multiple users then it gives more diverse effects on the conventional electronic contents just made for one user. In this paper our method gives new way for the conventional electronics book and it can define the user-centric gestures and help users to interact with the book easily. We expect our method can be utilized for many edutainment contents.

We are surrounded by so many images these days. These images have their own meanings and have an effect on our subject, whether consciously or unconsciously. Michel Foucault disclosed that upon closer examination the rationalism deeply rooted in Western society was not made autonomously but involuntarily by heteronomous power. Because the emotion of image within this relationship can be effectively conveyed just through its being seen, the image has been used for controlling and mustering people through the adjustment of its meaning by power. With the advance of technology and media of today, the image in this visual power is out of the object for reproduction, and then forms a new paradigm of manipulation, transformation and reproduction and is being changed to the formation of Panopticon power and its corresponding relationship.

The purpose of this study was to identify the effect of transcutaneous electrical nerve stimulation(TENS) and electroacupuncture(EA) after sciatic nerve crush injury in rats. Subjects were classified TENS group with TENS application, EA group with EA application and Control group which is not applicated electrical stimulation. TENS and EA stimulations were applied post-injury day(PD) 1 to 14 after sciatic nerve injury. This study observed c-fos expression in rat lumbar spinal cord. In addition, the paw withdrawal latency(PWL) and sciatic function index(SFI) were measured. The results were as follows: At PD 1, control group had higher c-fos immunoreactivity than experimental groups. At PD 7 and 14, control group had higher c-fos immunoreactivity than experimental groups. The PWL of experimental groups were significantly lower than control group. The SFI had not significant difference in all groups. But the average of experimental groups were higher than control group. These results suggest that TENS and EA applications increasing sensory and motor nerve recovery while decreasing c-fos immunoreactivity after sciatic nerve crush injury.

The profitability of a hospital refers to business administration results achieved through its medical care and other management activities during applicable fiscal year. This study focused on operating margin as a measurement index of hospital profitability, which is a genuine medical return obtained by subtracting medical expenses from medical profits achieved during business administration of hospital. Based on the index, this study could deduce certain factors on hospital profitability in terms of various indices affecting profitability. And based on those factors, this study sought to provide more useful reference materials which allow us to devise possible ways to improve hospital profitability. As a result, it was found that public hospitals attained lower profitability than private ones. To analyze profitability depending on each index, this study divided hospitals broadly into deficit group and surplus group. As a result, it was found that there were significant differences in hospital profitability between two groups depending upon relevant indices such as labor cost ratio, maintenance expense ratio, number of operations per medical specialist and medical instrument turnover. According to analysis on potential effects of relevant indices upon profitability, it was found that each index had its explanatory power ranging from 25% to 74.5% depending on given model.

There has been a diversity of therapeutic interventions for patients with chronic low back pain. However most of them have been focused on only pain. But the patients usually have a kind of structurally abnormal have fixed in lumbar vertebrae, which can decrease range of joint movement and, what is worse, reduce immediate dynamic balancing ability(IDBA). The reduced IDBA can increase the risk of injury and decrease coping ability in dangerous situation. So we introduced Maitland`s manual therapy in this study in order to recover the IDBA in patients with chronic low back pain. Sixty-four patients diagnosed with chronic low back pain were included for the study. Among them, thirty-two patients(experimental group) were managed by Maitland`s manual therapy, another thirty-tow patients(control group) were treated by physical science methods(H/P, TENS, U/S). Each group made use of highly reliable(0.81
0.96) star excursion balance test(SEBT) to compare the possible changes of IDBAs in two groups after treatment. In experimental group, IDBA has increased in forward, rightward, leftward, and backward, but in control group, not changed. According to the results, we concluded that Maitland`s manual therapy is effective for increasing IDBA by making joints more flexible in lumbar vertebrae.

The purpose of this study was to examine the periodontal disease awareness and periodontal health status of industrial workers in an attempt to help facilitate their prevention and treatment of periodontal diseases. The findings of the study were as follows: 1. In regard to a knowledge acquisition route on periodontal diseases, the largest number of the industrial workers investigated(36.3%) learned about the diseases from dental hospitals. As to scaling cycle, the younger workers deemed it necessary to get their teeth scaled every six months. In contrary, the older workers considered it advisable to do that about once a year. Age made a statistically significant difference to that (p<.05). 2. As for the state of the periodontal diseases of the workers, the greatest group (26.5%) found themselves to have something between their teeth often. The second most prevalent peridontal disease was gingival bleeding(24.5%), and the third largest group(24.5%) had teeth that were sensitive to cold. The fourth greatest group(15.9%) had the swollen gums from time to time, and the fifth largest group(4.5%) had shaken teeth. 3. Concerning the cause of periodontal diseases, the largest group (48.8%) cited an incorrect toothbrushing. As to the prevention of periodontal diseases, the greatest group(66.8%) viewed the right toothbrushing as the best way for that as well.

This study attempted to implement fundamental data to understand the relationship between self esteem and stress-coping strategies of current students in health related colleges for the development of a program related to school life and guidance. This study involved 244 willfully participating college students from six health related colleges in the Honam area. Data from self administered questionnaires regarding self esteem and stress-coping strategies were collected from November 1 to December 21, 2008. The results of the study showed self esteem was high when general characteristics of religion and a very harmonious relationship with classmates were present. Higher usage of active stress-coping strategies occurred as the year in college and mother`s education increased. Active implementation of passive stress-coping strategies were used when religion and residing in rural areas were present. Self esteem was higher as active stress coping strategies (i.e. problem focus and social support) improved. As passive stress-coping strategies (i.e. emotional relief and desire management) improved so did self esteem. By and large as stress-coping strategies increased for college students so did self esteem. As a result, as we search for stress-coping strategies pertaining to studies, practices, and future employment of college students, preparation of a regular course of study that includes curriculum, which increases self esteem should be made. Also consideration should be given to programs that promote relations between students and students and their advising professors.

We conducted a cross-sectional study of 799 adult males with alcohol consumption underwent laboratory investigation(control 297, alcoholic 206, nonalcoholic 296). The ultrasound scan of the liver was performed to determine the presence and the severity of FLD. We analyzed the association between the severity of AFLD & NAFLD and MS by logistic regression analysis. The distribution of metabolic syndrome was 7.4%, 48.8%, 34.9% in control, AFLD & NAFLD. The association of blood pressure, glucose, triglycerides, obesity were risk factor in AFLD & NAFLD. According to the severity of FLD, AFLD was significantly increased with MS, Obesity, low HDL-cholesterol. MS, High triglycerides was increased significantly in NAFLD(p<0.05). The prevalence of AFLD & NAFLD was increased with increasing the number of features of metabolic syndrome. This study shows that AFLD & NAFLD was closely associated with MS and its components. The patients of AFLD & NAFLD should managed and monitored to prevent metabolic abnormalities.

An abdominal aortic aneurysm occurs most commonly in older individuals (between 65 and 75), and more in men and smokers. The most important complication of an abdominal aortic aneurysm is rupture, which is most often a fatal event. An abdominal aortic aneurysm weakens the walls of the blood vessel, leaving it vulnerable to bursting open, or rupturing, and spilling large amounts of blood into the abdominal cavity. surface modeling is very useful to surgery for quantitative analysis of abdominal aortic aneurysm. the 3D representation and surface modeling an abdominal aortic aneurysm structure taken from Multi Detector Computed Tomography. The construction of the 3D model is generally carried out by staking the contours obtained from 2D segmentation of each CT slice, so the quality of the 3D model strongly defends on the precision of segmentation process. In this work we present deformable model algorithm. deformable model is an energy-minimizing spline guided by external constraint force. External force which we call Gradient Vector Flow, is computed as a diffusion of a gradient vectors of gray level or binary edge map derived from the image. Finally, we have used snakes successfully for abdominal aortic aneurysm segmentation the performance of snake was visually and quantitatively validated by experts.

This study set out to analyze the perceptions of investigative police officers and division police officers regarding Police Investigation Specialization, which had been in effect for four years, identify the problems, and search for alternative policies. The results led to the following alternative policies; first, the communication among the members should be facilitated by trading the jobs between investigative policemen and division members in certain percentage regularly, integrating job education and special work, and developing diverse support programs for detective activities to provide them with opportunities to experience and understand investigation. The second suggestion concerns the investigation members` morale. There should be a range of measures to boost their moral such as allocating separate budget and personnel to support the investigation department and the treatment of major criminal and civil cases, giving each investigation team an office and investigation room to improve their working environment, readjusting the promotion ratio of Police Investigation Specialization to introduce a promotion system proper for each investigation`s characteristics. The third suggestion is to secure job efficiency. It`s required to reinforce the current short-term specialized education program to bring up practical and professional investigators, open the certification exam of professional investigators to all members so that every policeman can have their abilities recognized and approved as long as they have the demanded capabilities, and create a system of shedding off the members idle at work by reflecting low performance records when evaluating the members to decide who to dismiss from Police Investigation Specialization. And finally, it`s important to divide duties rationally. The rationality of duties division can be guaranteed by setting the guidelines for direct handling for the team leader to help him devote himself to his duties, defining objective criteria of measuring investigation workload, and creating devoted systems and teams for simple and small accidents so that experienced investigators can deal with high-profile cases.

The selective central curriculum, which has been applied to the grades eleven and twelve in the 7th curriculum, has not operated well due to lack of teacher supply. This study analyzes the needs for the contents which are necessary to operate the minority optional curriculum through cyber education. Based on the developed contents, pilot program was performed. As a result of the program, the learning progress ratio of students was high but their satisfaction was very low. It is suggested that the quantity of the content should be reduced and the degree of difficulty lowered in order to address the problems. Another suggestion is to provide students with on-line teachers such as learning planners, tutors, and consultations to systematically manage students` learning. In addition, various elective-courses should be developed to allow students to take the courses of their choice, which in turn requires the establishment of the national operation system for the minority optional curriculum.
