Background: Health care services effort to provide alternative cardiac rehabilitation (CR) models to serve patients according to their preferences and needs. So, the present study aimed to assess and compare the effects of hospital-based and hybrid CR programs on chest pain intensity and discomfort in cardiac surgery patients. Methods: In this prospective study, 110 cardiac surgery patients were invited to the CR department of a hospital in the western part of Iran between March and July 2016. Patients were divided into two groups: hospital-based and hybrid CR. The hospital-based program included 26 sessions, and the hybrid program included 10 training sessions and exercise. The Brief Pain Inventory and Pain Discomfort Scale were used as research instrument, and data were analyzed using the paired t-test and ANCOVA. Results: The results indicated that both hospital-based and hybrid CR are effective in reducing the chest pain intensity and discomfort of cardiac surgery patients (P < 0.05). In addition, the comparison of scores before and after treatment using ANCOVA shows that no significant differences were observed between the two programs (P > 0.05). Conclusions: Traditional hospital-based CR delivery is still the first choice for treatment in developing countries. However, hybrid CR is as effective as a hospital-based program in reducing pain components and it includes only 38% of the total cost in comparison to hospital-based delivery. So, we recommend using hybrid CR according with the recommendations of American Heart Association about using CR for the management of angina symptoms.

Objective : This study aimed to show the possibility of neural canal enlargement and restoration of bony fragments through laminectomy and minimal facetectomy without pediculectomy or an anterior approach, and also to prove the adequacy of posterior stabilization of vertebral deformities after thoracolumbar bursting fracture. Methods : From January 2003 to June 2009, we experienced 45 patients with thoracolumbar burst fractures. All patients enrolled were presented with either a neural canal compromise of more than 40% with a Benzel-Larson Grade of VI, or more than 30% compromise with less than a Benzel-Larson Grade of V. Most important characteristic of our surgical procedure was repositioning retropulsed bone fragments using custom-designed instruments via laminectomy and minimal facetectomy without removing the fractured bone fragments. Beneath the dural sac, these custom-designed instruments could push the retropulsed bone fragments within the neural canal after the decompression and bone fragment repositioning. Results : The mean kyphotic deformities measured preoperatively and at follow-up within 12 months were 17.7 degrees (${\pm}6.4$ degrees) and 9.6 degrees (${\pm}5.2$ degrees), respectively. The mean midsagittal diameter improved from 8.8 mm (${\pm}2.8$ mm) before surgery to 14.2 mm (${\pm}1.6$ mm) at follow-up. The mean traumatic vertebral body height before surgery was 41.3% (${\pm}12.6%$). At follow-up assessment within 12 months, this score showed a statistically significant increase to 68.3% (${\pm}12.8%$). Neurological improvement occurred in all patients. Conclusion : Though controversy exists in the treatment of severe thoracolumbar burst fracture, we achieved effective radiological and clinical results in the cases of burst fractures causing severe canal compromise and spinal deformity by using this novel custom-designed instruments, via posterior approach alone.

1. Objectives : This study aimed to provide practical insights on the development of traditional Korean medical tourism and maximize the satisfaction of foreign patients. The main objectives of this study were also to evaluate Sasang Constitutional Medicine(S.C.M.) diagnosis cost from foreigners' perspectives. 2. Methods : For this study, the data were collected from tourists to Korea between January 3, 2010 to February 20, 2010. The sample used in this study was mainly composed of Japanese, Chines and US/Canada, because they are the major national visitor origin group to Korea. The primary data were collected by questionnaire survey using a standardized instrument with a convenience sampling procedure, and efforts of the interviews involved an on-site, self-administrated questionnaire to those sitting or visiting tourist attractions. The total size of the sample was 276 of which 275 showed no missing value against the factors needed for final analysis and were for analysis as an effective sample. SPSS 13.0 for window was used to analyze the collected data on which descriptive statistics and the Limited Dependent(LIMDEP) 8.0 program was used in estimating the willingness-to-pay(WTP) for traditional Korean medical tourism through the Contingent Valuation Method(CVM). A dichotomous choice question form of a CVM was applied to estimating the value. 3. Results and Conclusion: 1. There was significant statistical relationship between attributes when considering medical tourism destination and socio-demographic profiles such as age group, nationality, educational level and occupation. 2. In the level of recognition on Korean medicine, north Americans showed low level of recognition compared to other nationalities. In addition, in terms of age group, 20's and 30's showed low level of recognition on Korean medicine, 3. In relation to the level of interest on Korean medicine, Japanese respondents had higher interesting level on Korean medicine. Also singles had higher level of interest. 4. Regarding preferred Korean medical treatment program, there found significant statistical relationship between Korean medical treatment program and socio-demographic characteristics. 5. The estimating result of the logit model showed that the variables affecting the WTP for Sasang Constitutional medicine diagnosis were offered price and potential ability of medical tourism destination. 6. In relation to WTP for Sasang Constitutional medicine diagnosis, Japanese respondents showed a WTP of USD 62.69 and Chinese respondents showed USD 57.09. On the other hands, respondents from north America and other countries showed a WTP of USD 65.50. In conclusion, from this study, the results found that the opportunities in tradition Korean medical tourism are immense and the possible rewards are numerous. It is time to continue to promote 'Sasang Constitutional medicine' and make the Korean medical tourism programs considering on nationalities, age group, gender and WTP.

A primary goal of periodontal therapy is the creation of root surfaces that are free of plaque and calculus. It is not yet to be determined whether it is desirable to have a smooth root surface after treatment. It is also not clear what degree of roughness result from different instruments. In the present study various instruments for root surface debridement were evaluated. 20 extracted teeth were utilized, and the teeth were treated with one of the following instrument: Gracey curette, Perio Clean, and piezo ultrasonic device(Setlec, P Max) with general scaler tip, curette-like tip, and diamond tip. 3 dimensional planimetric device(Accura) was used to evaluate the average surface roughness. It was demonstrated hand and power-driven instruments did not have a significant difference in roughness of the root surface following instrumentation. And ultrasonic scaler tip tended to make a most smooth surface than other instruments. The possible reasons of the result were discussed.

It can be used easily to reduce rehabilitation and treatment time if diagnostic and therapeutic devices are attached to cloth or body. Therefore we developed neuromuscular wearable ultra-miniature lighting modules which can improve the neuromuscular function and verified its clinical effectiveness. The system is based on the ultra-miniature lighting treatment module and there are two types of systems. One of them is designed as an attached type and the other type is combined with clothing. The wearable ultra-miniature lighting module is composed of controller (battery, MCU, bidirectional transmitter and receiver), cable, treatment medium generating device and other peripheral devices. To verify the clinical effectiveness of this device, we observed the difference of the strength of a muscle before and after 650nm and 25mW laser irradiation on the reflex point for 1 to 4 seconds. Among 48 patients having the degenerative osteoarthritis, the muscle strength before and after irradiation of laser was $21.8{\pm}7.99$ and $27.3{\pm}8.43$. According to the result, the muscle strength after treatment was significantly increased (p<0.01). To whom having difficulty in visiting to OPD(Out-Patient Department), doctors medically examine the patients and find the therapeutic point, attachment of this wearable ultra-miniature lighting module can function as self treatment (treating instrument) and treatment assist at home. If doctor can remotely control the patient and take part in treatment, the therapeutic device could contribute to prevention and care device.

Purpose: To identify the incidence of cutaneous injury in clinical nurses. Method: From Feb.1 to 28, 2005, 276 clinical nurses were surveyed by questionnaire. Results: 1. Of the nurses, 53.6% had at least one incidence of cutaneous injury, and the mean number of injuries was 1.34. A higher incidence rate for cutaneous injury was found in nurses who were under the age of 25, unmarried and who had less than 3 years career experience. 2. The major causes of injury were syringe needles at 65.0%, and medical instrument were next followed by sharp objects or blades. The injuries occurred when the nurses were rearranging equipment after care (25.2%), taking blood samples (22.8%), separating syringes and needles (17.1%), during surgical operations (14.2%), and distribution of medications, treatments and recapping of needles (5.7% each). The hands were the most common body parts injured, and the most prevalent pathogens contaminating the instruments causing the injury were HBV syphilis, HCV and HIV in that order. 3. Of the injured nurses, 77.9% did not report the accident and 25.8% did not receive any treatment because there were no pathogens, it was a bother or there was difficulty reporting the incident. Conclusion: To reduce cutaneous injuries, intensive training and supervision may be needed for those of nurses under the age of 25, unmarried and with less than 3 years career experience.

The purpose of this research is to discover changes of WBC and ANC numbers before and after applying Oriental medicine therapy to blood cancer patients. After that, appropriate music therapy method was well planned and carried for patients. Demonstration and music were conducted according to Ohaeng theory. The oriental music therapy was conducted three hours everyday by listening to music and we made patients participate in playing the instrument for one hour in two times a week. The result was verified in three ways by checking and comparing numbers of WBC, ratio of ANC and New Trophil before and after the experiment. In addition to that verification, we analyzed patients' survey and their response after treatment. The result was that WBC and ANC were efficient as p=0.0419, p=0.0262 each and the ratio of New trophil was not efficient in p=0.999, but partially increased.
