  • The objective of this study was to document how clinical dietitians working at tertiary hospitals spend their time based on several categories of activities using a time measurement study. The questionnaires were distributed to 14 tertiary hospitals, and dietitians answered by classifying their work activities into several categories such as general care, indirect care, direct care, outpatient care, and food service management. A total of 129 clinical dietitians replied and their answers were analyzed according to the categories of activities. The times spent on the categories are as follows: general care (76.7 mins/day, 14%), indirect care (228.4 mins/day, 35%), direct care (120.1 mins/day, 22%), outpatient care (61.5 mins/day, 11%), and food service management (99.0 mins/day, 18%). The total working hours for dietitians was 590.0 mins, which exceeds the standard working hours of 540.0 mins (9 hrs) a day. From this study, we found that clinical dietitians spent very limited time on direct care. Times spent on activities were different according to type of employment and food service. Internship dietitians spent their more time on general care (P<0.001) while irregular dietitians spent more time on outpatient care (P<0.05). In contracted managed food service hospitals, clinical dietitians spent significantly less time on food service management (P<0.001). Regardless of doctors' order and consultation fees, clinical dietitians performed more than 95 percent of free consultation to patients. Entry-level knowledge and skills of dietitians working at hospitals are very important for quality service, but it is equally important to create an administrative and social environment that encourages clinical dietitian to spend more time on direct patient care.

  • In the medical environment today, new technology has compelled new work paradigm, as it has been other areas of our lives. However it is very difficult to see the changes that have been taken place, even though new computer technology has changed the medical industry so rapidly. In this study, new concept of human computer interaction focusing on tangible interaction for anaesthetic procedure in an operating theatre has been explored with a 5 years technological and social perspective. This project is not intended to redesign the equipment itself but to focus on enhanced human computer interaction concepts. The exper iment shows that how new technology affects anaesthetic nurses' work in an operating theatre in the near future to improve quality of the medical service by helping to increase work efficiency and enhance patient satisfaction. As a result of the study, the KEY brings new visions to the anaesthetic nurses via various types of interaction. Thanks to the KEY, the nurse is really free from the machines so that he can keep attention to patient most of the time during the whole operation. The discussion in this study is still preliminary, and further elaboration is strongly needed. It might be certain that additional further studies, such as high-fidelity prototyping and logistical user testing, should be followed not only to refine and communicate the ideas to audiences, but as a means of stimulating and generating further ideas.

  • It is well known the fact that turbo lodes has better performance as the number of iteration and the interleaver size increases in the AWGN channel environment. However, as the number of iteration and the interleaver size are increased, it is required much delay and computation for iterative decoding, and caused the flattening effect phenomenon which is very litter BER performance improvement at the arbitrary SNR. In this paper, We proposed the new asymmetric turbo codes, which consist of parallel concatenated turbo codes that use mixed types of component codes with different not only constraint length but also generate polynomial and analyzed its BER performance for log-MAP decoding algorithm with frame size of 128, 256, 512 and 1024 bits, and coding rate of 1/3. As a results of simulation, proposed asymmetric turbo codes verify that its BER performance is superior to conventional symmetric turbo codes. It can be also observed that the flattening effect phenomenon is very reduced by applying the proposed asymmetric turbo codes. It gains respectively 1.7dB ~2.5dB and 2.0dB~2.5dB SNR improvements in the case of short frame(128, 256) and large frame(512, 1024) size for the BER $10_{-4}$>/TEX> region.

  • Peri-implantitis could be the result of biomechanical and occlusal overload as well as microbiologic invasion. The dental implant may be more susceptible to dental plaque than the natural tooth, as the predictability of a stable soft tissue attachment complex has not yet been confirmed. With the development of peri-implantitis, the implant surface would be exposed to the oral environment and becomes coated with bacteria. The objective of therapy for this condition is to regain integration of the implant with bone. Since fibroblast adherence to surfaces is impeded by endotoxin, it would seem that decontamination would be desirable to obtain maximum osseointegration. The purpose of this study was to determine whether various chemotherapeutic and mechanical treatments(distilled water, air-powder abrasive, hypersaturated citric acid, tetracycline) can detoxify contaminated titanium implant surface by means of kinetic LAL test. Experimental rough surface titanium disks were fabricated. All of them were divided into two groups(A.a group and P.g group) and each contaminated by A. actinomycetemcomitans and P. gingivalis suspension. Contaminated disks were treated with distilled water, air-powder abrasive, citric acid and tetracycline, and then all disks were placed into LPS-free water for elution. The results were as follows : 1. In A.a group, LPS elute level of all test groups were significantly lower than control group(p<0.05). 2. In A.a group, LPS elute level of test 2, test 3 and test4 groups were significantly lower than that of control group(p<0.05). But, among the test 2, test 3, test4 groups, the significant differences were not detected. 3. In P.g group, LPS elute level of test 2, test 3 and test 4 groups were lower than that of control group(p<0.05). But, among the test groups, the significant differences were not detected. From the result of this study, it would be concluded that air-powder abrasive, hypersaturated citric acid and tetracycline treatments may be effective at reducing endotoxin level on rough titanium implant surfaces, and can be clinically used. But the treatments in peri-implantitis differentially impact osseointegration making one method clinically superior. To gain this knowledges, further molecular biologic and histopathologic studies should be developed.

  • A peripheral nerve when approximation of the ends imparts tension at the anastomosis and with a relatively long segment defect after excision of neuroma and neurofibroma cannnot be repaired by early primary suture. The one of the optimistic reconstruction method of severed peripheral nerves is to restore tension-free continuity at the repair site putting an autogenous nerve graft into the neural gap despite of ancipating motor or sensory deficit of the donor nerve area. To overcome the deficit of the autogenous nerve graft, several other conduits supplying a metabolically active environment which is able to support axon regeneration and progression, providing protection against scar invasion, and guiding the regrowing axons to the distal stump of the nerve have been studied. An author have used ipsilateral femoral vein, ipsilateral femoral vein filled with fresh thigh muscle, and autogenous sciatic nerve for the sciatic nerve defect of around 10 mm in length to observe the regeneration pattern in rat by light and electron microscopy. The results were as follows. 1. Light microscopically regeneration pattern of nerve fibers in the autogenous graft group was more abundant than vein graft and vein filled with muscle group. 2. On ultrastructural findings, the proxial end of the graft in various groups showed similar regenerating features of the axons, myelin sheaths, and Schwann cells. The fascicular arrangement of the myelinated and unmyelinated fibers was same regardless of the type of conduits. There were more or less increasing tendency in the number and the diameter of myelinated fibers correlated with the regeneration time. 3. In the middle of the graft, myelinated nerve fibers of vein filled with muscle group were more in number and myelin sheath was thinner than in the venous graft, but the number of regenerating axons in autogenous nerve graft was superior to that in both groups of the graft. The amount of collagen fibrils and amorphous materials in the endoneurial space was increased to elapsed time. 4. There was no difference in regenerating patterns of the nerve fibers of distal end of the graft. The size and shape of the myelinated nerve fbers were more different than that of proximal and middle portion of the graft. From the above results, the degree of myelination and regenerating activity in autogenous nerve is more effective and active in other types of the graft and there were no morphological differences in either ends of the graft regardless of regeneration time.
