Purpose : This study was conducted to analyze the results of arthroscopic ankle arthrodesis and to verify the advantages of the technique compared to open ankle arthrodesis. Materials and Methods : Between October 1992 and August 1996, the arthroscopic ankle arthrodesis had been performed in five patients(six ankle joints): two patients with seropositive rheumatoid arthritis(one patient surgically treated bilaterally), two with osteoarthritis and one with tuberculous arthritis. There were one man and 4 women. Average age was 48 years ranging from 38 to 65 years. Follow up period was average 45 months(range, $12\~80$). Results : All patients were successfully treated with ankle joint arthrodesis under arthroscopic control. The mean time to fusion was 10 weeks(range, $6\~15$). There was a $100\%$ fusion rate without any complication. Conclusion : The arthroscopic ankle arthrodesis was successful in all cases with less morbidity and short hospital stay. It was technically feasible with excellent predictability.

Purpose: To investigate the causes of failure on ACL reconstructions and evaluate the effectiveness of one stage revision ACL reconstructions. Materials and Methods: From November 2004 to July 2008, thirty three patients who had got revision ACL recontstructions after reruptures of ACL were evaluated. The causes of failure of ACL reruptures were 22 vertical femoral tunnels, 7 neglected PLRI, 3 severe traumas and 1 deep infection after ACL reconstruction. The femoral tunnels were aimed at the 10 or 2 o'clock position and the tibial tunnels were used with previous tunnels. Previous femoral screws from the improper femoral tunnels were removed and filled with the new allograft bones. Results: The average periods of follow up were 22.2 months (12~52 months). There was improvement on an average Lysholm knee score from $61.5{\pm}16.8$ to $86.3{\pm}11.5$, IKDC score from $63.9{\pm}15.1$ to $81.3{\pm}14.3$. Mean side to side difference was decreased from $6.0{\pm}2.2\;mm$ to $1.6{\pm}1.4\;mm$ using KT-2000 arthrometer. Conclusion: One stage revision ACL reconstruction can be a useful method with good clinical results.

The study was conducted in order to systematize specialization of flower decoration. The results of this study are summarized as follows. The research of image adjectives were analyzed into a total of 4 factors, which are texture, color, period, decoration. With regard to texture, the flower with the highest texture of 2.00 was white Zantedeschia aethiopica and that with the lowest texture of -1.90 was Leucospermum cordifolium. In regard of color, the flower with the highest color of 1.70 was Rosa 'Judy' and that with the lowest color of -2.40 was Gypsophila. With regard to period, the flower with the highest period of 2.00 was Gomphrena globosa and that of the lowest of -3.00 was Leucospermum cordifolium. In decoration, the flower with the highest decoration of 2.50 was Agapanthus 'Intermedia' and that with the lowest decoration of -2.00 was Heliconia bihai 'Lobster'. As for correlation among the factors, color and period were in a correlation with each other. It shows that color and period are the most important factors in flower decoration. In result of conjoint analysis, importance was high in order of color, texture, decoration and period. This suggests that consumers overemphasize color and texture in flower decoration and may fail to notice the importance of period.

This paper proposes how to fabricate an educational Mach-Zehnder interferometer that is easy to align and inexpensive, using 3D printers and semiconductor lasers. The interferometer consists of a body $165mm{\times}120mm{\times}57mm$ in size, mirror mounts, a laser holder, beam splitters, and so on. The laser path is adjusted by 4 mirror mounts, each comprised of rubber bands, small metal wires, and a screw. The interference fringe is enlarged by the lens at the final stage. The refractive index of a slide glass was measured by counting the number of moving interference fringes while the slide glass, inserted into one of the two interferometer arms, is rotating. The formula for the refractive index as a function of the optical-path difference and rotation angle was obtained, and used to calculate the refractive index of glass from the interferometer experiment. The use of a rotating glass in one arm of the interferometer nullifies the need for a precision stage, which despite its high cost is often required to observe the moving interference fringe in the classroom. Therefore, the 3D-printed Mach-Zehnder interferometer proposed in this paper can be very useful for education, because of its affordability and performance. It enables students to perform both qualitative and quantitative studies using a 3D-printed interferometer, such as measuring the refractive index of a glass sample, and the wavelength of light.

All-on-six concept can be used as one of the treatment options to maximize the use of available residual alveolar bone for implant-supported fixed prosthesis on edentulous patients. But this process is complex and cumbersome. Digital system can be used at multiple steps, from implantation to prosthetic restoration, to overcome this shortcoming. In this case of a maxillary edentulous patient aged 76, digital system was used for restoration of 1-piece design, screw retained fixed prosthesis from diagnosis, implant surgery to fabrication of provisional and final prosthesis. For preoperative diagnosis and treatment planning stage, intra-oral information of a patient was digitalized by direct intra-oral scan. Surgical guide and immediate provisional prosthesis was designed based on this digitalized data. Patient's inconvenience was minimized by applying immediate provisional prosthesis, which was delicately fabricated according to the location data of six implants on most suitable residual alveolar bone. Then, final prosthesis was designed and fabricated going through new interim prosthesis which was newly designed and fabricated, considering patient's requests, stable vertical dimension and occlusion, and esthetic factors using digital system. We hereby report a case successfully applying digital system to multiple steps including implant surgery to fabricating prosthesis, to simplify existing complicated implant treatment procedure to an edentulous patient.

This study was conducted to identify the effects of pressure taping between tibia and fibula of High Ankle Sprain athletes on pain, Range of Motion(ROM), and strength and to provide basic data for rehabilitation programs. The subjects of the study were conducted with a total of 10 athletes except for four who gave up who were diagnosed with high ankle sprain, or who were diagnosed with ankle sprain but their physical examinations proved positive. The results showed no significant differences in pain(Visual Analog Scale, VAS). The ROM was significantly increased in inversion(IV) and eversion(EV) in both groups. The Isometric strength was significantly improved in IV(0°, 7°, 14°) and EV(0°) in Taping Group(TG). When taping was applied to athletes with injury to the High Ankle Sprain, ROM and muscle strength improved at the same pain level.

The objective of this study is to suggest measures to support the community-based rehabilitation sports service for health of people with disabilities, which can be applicable to South Korea, by analyzing the rehabilitation sports service support system of Germany and Japan. Through literature review and direct visiting to Japan, the researcher explored such factors as, background of initiating the rehabilitation sports service, concept, range, and subject of theservice, service delivery procedure, and institutions, and finance of the service. The institutional implications are as follows: First, the concept and range of rehabilitation sports are gradually expanding. Initially, the rehabilitation sports started targeting for veterans with disabilities for the purpose of medical rehabilitation in Germany and Japan. As time passes, however, the importance of rehabilitation sports has emphasized, and the subjects have gradually expanded for the purpose of preventing disability or secondary diseases caused by disability. Second, in order to perform rehabilitation sports service, it is essential to have manpower with expertise in medical treatment, welfare, disability, and exercise prescription, likewise Germany and Japan do. Third, Germany and Japan emphasize the assignment of rehabilitation sports instructors in institutions, rather designating specific institutions, which is moving toward the manpower-based rehabilitation sports service, rather place-based service. Fourth, rather having simple medical programs or sports-oriented programs, it would be necessary to have the systematized disease-oriented programs for each type of disability. Lastly, the clients-oriented service delivery process should be established.

Passive fit of prosthesis is an essential property of implant supported prosthesis for long term success and minimization of complications. And the property is determined mostly by fabrication procedure. There were limitations of extensive implant prosthesis because conventional casting method generate contraction error of long span prosthesis. However, Computer-aided design/Computer-aided manufacturing (CAD/CAM) technology of 3D printing and milling metal framework can overcome those limitations. This case is a full mouth rehabilitation using extensive implant fixed prosthesis. Removable interim prosthesis was made for esthetic, functional evaluation and a guide for implant insertion. After the insertion, implant fixed interim prosthesis was delivered. After additional evaluation and adjustment, final prosthesis was designed with CAD, the fabricated with CAM. Milling technique was used for anterior screw type implant superstructure and 3D printing technique was used for the anterior and posterior implant copings. Fit of the final restoration was favorable. The practitioner and patient were both esthetically and functionally satisfied with the final result.
