  • A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according te anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible accord-ing to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyze the effects of bone engagement and implant length on stress distribution. ANSYS 5.5 finite element program was utilized as an interpreting toot. Three cases of unicortical anchorage model with 7, 10, 13 mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13 mm length were compared both maxillary and mandibular single implant situation. Within the limits of study, following conclusions were drawn. 1. There is a difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant future length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

  • This study was conducted to follow the patient referral system operated from the primary health care facilities to the hospital in a rural area of Korea. The subject for this study was sampled from a community health development project carried out by the Korea University in Yeoju Kun, Kyonggi Province. The data of referred patients from primary health care facilities were collected during the period from January 1989 to December 1989. The data was sorted out by a computer system using Database package. The results of this study were summarized as follows: 1. Characteristics of the referred patients were: males $32.0\%$. and females $68.0\%$. The more elderly of the patients visited to the hospital after having been referred there by CHPs or public physicians, $25.9\%$ has been to hospital on at least one previous occasion as against $74.1\%$ for whom it was there first visit. 2. The majority of patients who were referred to a hospital where: medicine $44.3\%$ and orthopedics$16.4\%$, major diseases were : diseases of digestive system $(21.3\%)$ ; symptoms and ill defined conditions $(17.3\%)$ ; diseases of the muscular skeletal system and connective tissue$(14.2\%)$. chronic illness was $82.0\%$ and acute illlness was $18.0\%$. 3. From Community health practitioners more patients referred than the public physicians. Categoris of diseases of the referred patients were different between community health practitioners and public physicians. Due to the. respective differences between the medical restrictions put on the nursing staffs at the community health practitioners and public physicians. From this study it was recommended to define the reason of differences between ~he two groups in futher study. Study as to 1) why one group should be referring more for hospital treatment than the other. And 2) why the two agencies should be referring different diseases.

  • Objectives : This study was aimed to promote the cooperative system of Korean and Western medicine in the dual health care system through a survey of physicians on recognition, problems and solution of the cooperative system. Methods : The research took place at Dongguk University Hospital from May 25 to 27, 2009 with 44 professors, residents, and interns employed by the hospital. Results : Of total 44 surveyed doctors, positive and moderate responses on the cooperative system between Korean and Western medicines were 40.9% and 43.2%, respectively. They scored it positive (62.5%) and moderate (31.3%) based on their experiences. These results can be supposed to represent the environment for the interdisciplinary medicine. Even in the interdisciplinary hospital of Korean and Western medicine, 68.2% of responders had no experience of the cooperative medical system. Expected interdisciplinary efficient departments were ordered rehabilitation medicine, neurology and orthopedics and associated with musculoskeletal disorders, the most frequent diseases treated by Korean traditional medicine. Conclusions : Korean and Western medical doctors, as medical personnel, intellectual persons as well as specialists, need a recognition and attitude to understand and respect each others' medicine. However, both groups also realize there are many complicated issues in the treatment of patients. It is difficult to require a change of Western doctors' perceptions and attitude toward Korean traditional medicine only with results of a survey. For the efficient cooperative system in the medical field, Korean medical doctors will need to study and consider specific problems mentioned by Western medicine.

  • Osteoarthritis(OA) is a widespread, slowly developing disease with a high prevalence rate increasing with age. The most common big joints involved in OA is the knee, where the disease particulary strikes, causing difficulties in rising from a chair. climbing stairs, kneeling. standing, and walking. The primary complaints of these patients include pain, stiffness. instability, and loss of function. The purpose of this study was to assess the impact of self-reported symptoms and limited flexion, and limited extension on functional impairment in patients with knee osteoarthritis. In the data collection, a total of 206 who had visited the physiotherapy unit at six different departments of orthopedics were interviewed in K City from June to September, 2000. The results of the study summarized are as fellows: 1. There was a significant difference among different degree group of limited flexion(p<0.05). A group difference was demonstrated between <5 ${\sim}$ 15 and 16 > (F=16.21, p<0.05). In the relationship between the degree of limited flexion and the level of functional impairment, the h igher the range of limited flexion, the lower the level of functional impairment. 2. In the relationship between the degree of limited extension and the level of functional impairment, a group difference was revealed between the non-limitation group and the <10 and 11 < However, no significant difference was noted between 11 ${\sim}$ 20 and 21 >(F= 13.37, p<0.05). In conclusion, finding above suggest that functional impairment is closely correlated with limited tlexion and extenion

  • Background: Breast cancer usually shows a slow development rate and when it is recognized in early stages very successful treatment results can be achieved. This research was planned to research the health beliefs of nursing faculty students about breast cancer and breast self-examination (BSE). Materials and Methods: The first class students of nursing faculty formed the basis for this descriptive research (N=347). Sample selection was not made and all female students who wanted to participate voluntarily in the research during March-May of 2014 were included (n=331). Results: It was determined that 85.5% of students had knowledge about cancer, 79.5 % knew of breast cancer, and 65.3% were aware of how BSE is performed. According to the responses of students to the scale of the health belief model that is used to determine the health beliefs of students, item-point averages of trust and obstacle sub-dimensions were high. Conclusions: It is determined that more than half of students had knowledge about breast cancer and breast self-examination. Their health beliefs were affected by trust and obstacle perceptions, knowledge level about cancer, and awareness about how BSE is done. These factors should be considered in planning trainings that will be given to students. Social responsibility projects should have designed to create the awareness that cancer is a treatable disease.

  • Objective: The purpose of this study was to examine the possible effects of incorporating short-term slow-abdominal respiration (SAR) into an exercise program, on balance and the cardiac-related autonomic nervous system (ANS). Design: Cross-over repeated measures design. Methods: Fifteen young and healthy adults were randomly assigned into two groups (7 in the C-R group, 8 in the R-C group), each of which carried out both control sequence (C) and respiration-experiment sequence (R) in the inverse order. In the C sequence, the subjects performed passive exercises and a general exercise program (P-GEP). In the R sequence, the subjects received a short-term SAR training session and then performed the respiration incorporated general exercises program (R-RGEP). Before and after both C and R sequences, the length and the area of the displacement of the center of pressure (COP) and heart rate variability parameters were measured. Results: The total length of the COP displacement in the left single-leg-standing condition showed a significantly greater reduction after R-RGEP in the respiration-experiment sequence than after the P-GEP in the control sequence (p<0.05). The mean heart rate was significantly reduced only after R-RGEP in the respiration-experiment sequence (p<0.05) Conclusions: The slow-abdominal-respiration, trained in a simple manner and integrated into the exercise program in a single session, showed partially positive immediate effects on balance stabilization. The decrease in heart rate indicated possible involvement of the parasympathetic ANS activation in the stability, although it is not enough to decide whether it is purely due to the controlled respiration.

  • Volkmann's ischemic contracture is the end result of an untreated, delayed or Inadequately decompressed compartment syndrome in which muscle ischemia and necrosis have occurred. Once the muscle necrosis have happened, the involved muscle undergo permanent change into fibrous tissue. So secondary shortening and distal joint contracture will be a final outcome, which results in marked functional impairment of hand and forearm. Even though several procedures, such as muscle sliding operation has been attempted, overall results were far from satisfaction, compare to healthy opposite hand. The management of these unfavorable condition of the forearm and hand was regarded as one of challenging area in orthopedics. Recently new approach, using microsurgical technique which transfers functioning muscle unit, has been developed and its result was much better than any other methods in the aspect of an active motion. Among these musculocutaneous free flaps, gracilis has obtained special reputation due to its easiness to handle such as elevation of flap and reliable neurovascular pedicle. Other advantages are flexibility of flap size to adjust variable size of the defect in the forearm and minor morbidity of the donor site. Authors have performed 7 cases of functioning gracilis musulocutaneous free flap transplantation for the functional loss of forearm and hand due to Volkmann's ischemic contracture or muscle and skin defect due to severe trauma since November, 1981 till May, 1991. The results in most cases were satisfactory and acceptable.

  • Background: Common and effective treatments for calcific tendinitis involve needling procedures. However, it has been widespread practice to refer patients with calcific tendinitis, which is a predominantly orthopedic condition, to radiology department. The purpose of this study was to compare clinical and radiological outcomes after ultrasound-guided needling for calcific tendinitis between the orthopedics and radiology department. Methods: Seventy-seven shoulders (Group 1) and 38 shoulders (Group 2) treated in the radiology and orthopedic department, respectively. A fellowship-trained orthopedic surgeon and a musculoskeletal radiologist each performed the procedure of ultrasound-guided needle decompression with subacromial steroid injection. Clinical outcomes was evaluated using the visual analogue scale for pain (pVAS) and the American Shoulder and Elbow Surgeons (ASES) shoulder score before treatment and at each follow-up. The pre- and postneedling size and shape of the calcific deposits were compared between the two groups. Results: We analyzed a total of 56 shoulders for Group 1 and 32 shoulders for Group 2. The mean age and sex ratio of the patients no significantly different. We found that the mean decrease in the diameter of calcification between pre- and post-needling was 9.0 mm for Group 1 and 13.1 mm for Group 2; the difference was significantly larger in Group 2 than in Group 1. Both groups showed improved pVAS and ASES scores after needling but the extent of these improvements did not differ with the type of operator. Conclusions: Needling decompression performed by orthopedic surgeons could a viable option for the treatment of calcific tendinitis.

  • Three dogs were presented with diaphyseal fracture of the tibia following separate motor vehicle accidents. On physical and orthopedic examinations, the dogs were noted to have soft-tissue swelling and a closed fracture in these tibia sites. Radiographs revealed a simple, short oblique fracture (case 1), a comminuted, spiral fracture (case 2), and a simple, spiral fracture (case 3) in tibia. Minimally invasive percutaneous plate osteosynthesis (MIPO) using a veterinary cuttable plate or locking plate was applied for the treatment of these fractures. The surgery was successful, and the fractures healed without any complications by 7 weeks (case 1), 10 weeks (case 2) and 8 weeks (case 3) after surgery. Our patients showed fast bone healing times and early weight-bearing during the treatment of their tibia fractures. Therefore, MIPO was a useful procedure for diaphyseal fracture of the tibia in veterinary orthopedics.
