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.

This study was designed to determine the effect of different floor space and type of finishing building on performance, behaviour and carcass quality of finishing pig. Three hundred and thirty six finishing pigs were alloted into two space allowance ($1.0m^2$and $2.5m^2$/pig) and two floor type (concrete slat and bedded with sawdust) of finishing building. There was no significant difference between the different space allowance in the body gain, feed intake and feed per gain. And also floor type of finishing building was not affected by the performance of finishing pig. Space allowance per pig affected the maintenance behaviour, but there was no significant difference between the floor type of finishing building in the spent time on lying, sitting and standing. Floor type was affected by the occurrence of standing behaviour, the finishing pigs in the bedded with sawdust showed less occurrence of standing. Carcass traits did not show any significant difference due to the difference of space allowance and floor type of finishing building. There was no significant difference in the chemical compositions of pork loin between the space allowance and floor type of finishing building.

Currently, Intelligent femoral prostheses that support the corresponding mode in walking and specific movements are being studied. Certain controls such as upstairs, sitting, and standing require a technique to classify control commands based on the user's intention because the mode must be changed before the operation. Therefore, in this paper, we propose a technique that can classify various control commands based on the user's intention in the intelligent thigh prosthesis system. If it is determined that the EMG signal needs to be compensated, the proposed technique compensates the EMG signal using the correlation between the strength and frequency components of the normal EMG signal and the muscle volume estimated by the pressure sensor. Through the experiment, it was confirmed that the user's intention was accurately detected even in the situation where muscle fatigue was accumulated. Improved intention detection techniques allow five control modes to be distinguished based on the number of muscle contractions within a given period of time. The results of the experiment confirmed that 97.5% accuracy was achieved through muscle tone compensation even if the strength of the muscle signal was different from normal due to muscle fatigue after exercise.

Since 1979 forty-three cancer patients have been given intrathecal block at the pain clinic of Yonsei Medical Center. The male patients numbered 23 and female 20 and most of them were in the 4th and 5th decades of age. In 78.6% of the patients, the diagnosis was rectal cancer in 20 cases, cervix cancer in 7 cases, bladder cancer in 4 cases and colon cancer in 3 cases. Thirty six patients with cancer pain were treated by intrathecal 10% phenol-glycerine block and rest of them had only test block. Fourteen patients whose pain sites were lumbar or lumbar and upper sacral dermatomes were put into the lateral recumbent position on the fluoroscopic table. The spinal puncture was performed as close to the spinal roots to be impregnated as possible. In 22 patients the pain sites were covered by the sacral dermatomes and so the L5-S1 interspace was punctured in the sitting position shifted 15 degree to the affected site. Fifty one blocks were performed and their results are classified into three categories: good, fair antral poor. We achieved good results in 38 patients(77.1%), fair in 6 patients(17.1%) and poor in 2 patient(5.7%). Thus a satisfactory pain relief was achieved in 94.2% of patients. After intrathecal block with phenol glycerine, transient voiding difficulty was noted in 7, defecation difficulty in 1, and transient paresthesia and/or muscle weakness was present in 3 patients. The mean duration of pain relief was 2.5 months and longer than the mean survival time of 2.25 months. When patients are selected carefully and tile block is performed with great caution and good technique, the risk is minimal and a long lasting relief of intractable cancer pain achieves a painless life until death.

This study was conducted for behavioral characteristic analysis of the Asiatic Black Bear in a limited space. Behaviors of eight Asiatic Black Bears were classified into 13 normal stances and locomotor activities, 15 normal maintenance behaviors, 9 locomotory compulsive behaviors, 2 non-locomotory compulsive behaviors through the 3 years of monitoring. The bears had originally been released into the Jiri National Park for Asiatic Black Bear Restoration Project and were withdrawn again because of several reasons such as habituation to humans, and apiary damage. Through the monitoring of 6 hours per day during 3 months, classified behaviors were analyzed based on sex, age, observing month, observing timing, captivity period, and captive form. The total rate of stereotypic behaviors was $26.51{\pm}13.38%$. Among these, RA(Rest_A) was rated high as $47.32{\pm}18.32%$. In addition, SP(Standard pace), HR(Head rear), EP(Extended pace) were most frequently observed behaviors. The time budget of TFS(Two feet stand), SA(Sniff_A) and SB(Sniff_B) on females and younger individuals were relatively higher than male and older individuals. So we confirmed that females and younger individuals had more wariness and curiosity. As the period of captivity took longer, the rate of stereotypic behaviors was higher and more stereotypic behaviors were observed in the afternoon. At night, behaviors related with resting like Rest-A, Rest-B, Lying down, Lying on abdomen, Sitting were more frequently observed. We concluded that the captive state could affect the behaviors of Asiatic Black Bear and long term research should be necessary.

Objective: Psychomotor imagery has been widely used to improve motor performance and motor learning. Recent research suggests that during visualization, changes occur in neurophysiological networks that make physical practice more effective in configuring functional networks for skillful behaviors. The aim of our pilot study was to determine if there was change and to what extent there was differentiation in modulation in electroencephalography (EEG) frequencies between visualizing a state of rest and a state of exercise performance and to identify the preponderant frequency. Design: Quasi-experimental design uncontrolled before and after study. Methods: EEG brain wave activity was recorded from 0-40 Hz from nine cerebral cortical scalp regions F3, Fz, F4, C3, Cz, C4, P3, POz, and P4 with a wireless telemetric EEG system. The subjects, while sitting on a chair with eyes closed, were asked to visualize themselves in a state of routine rest/relaxation and after a period of time in a state of their routine exercise performance. Results: The gamma frequency, 31-40 Hz, (${\gamma}$) was the predominant wave band in differentiation between visualizing a state of rest versus visualizing a state of exercise performance. Conclusions: We suggest these preliminarily findings show the EEG electrocortical activity for athletes is differentially modulated during visualization of exercise performance in comparison to rest with a predominant ${\gamma}$ wave band frequency observed during the state of exercise. Further controlled experimental studies will be performed to elaborate these observations and delineate the significance to optimization of psychomotor exercise performance.

The purpose of this study was to develop a balance chair for improving pelvic correction and postural balance through postural balance training using tactile feedback by a vibration motor provided in real time according to the user's attitude. We built a body frame using mono cast(MC) Nylon, Touch thin film transistor(TFT) for user interface, a main control module using Arduino, a 9-axis acceleration sensor for user's posture determination, and a vibration module for tactile feedback. The prototype of the Balance Chair which surrounds the outside was made with cushion for sitting conformability. In order to verify the effectiveness of the postural balance training system using the built prototype, the muscle activity (% MVIC) of the left and right iliocostalis lumborum those are the main muscles of the spinal movement was measured with ten female subjects. And the balance ability before and after training was measured using Spine Balance 3D, a posture balance ability evaluation device. The muscular activities of the left and right iliocostalis lumborum showed the balance activation according to vibration feedback during exercise protocol and postural balance improved after balance exercise training using balance chair. This study could be apply to use the fundamental research for developing the various postural balance product.

The purpose of this study is to understand the principles of Balletfit and its program structure and to establish Balletfit's effects on body shape change and postural correction. Interview, the most commonly used method of qualitative research, was chosen as the research method. Ten Balletfit class participants, who have attended private lessons twice per week, for three to six months period of time, were selected. These participants were chosen from participants of private lessons instead of group lessons for in-depth insights. The research was limited to a small group of participants and therefore, it is difficult to standardize the result. Also, because this study is based on the opinions of the participants, not by a posture measuring device, the accuracy of the result is limited as well. The followings are the conclusion of this research. First, the participation motive was either internet research or acquaintance's recommendation. Secondly, the effort to change the body shape. After experiencing Balletfit classes, the participants became aware of their body and made an effort to recover their posture by holding the stomach tight and sitting up correctly. Thirdly, their posture became ideal. Most participants became aware of what an ideal posture is and as their body became ideal, the participants also recovered their health by becoming aware of their inner and outer body. Lastly, they tend to prefer beautiful body line. After the experience, all participants became interested in the body line and preferred to build a beautiful body line with correct postures. The most significant effect of Balletfit was the body line. Therefore, the experience of Balletfit develops the inner and outer body awareness and also can be consider to effect the change of the body shape. Balletfit will become a satisfying exercise for modern people, who desire a beautiful, healthy body.

Purpose: The ischial area is by far the most common site of pressure sores found in wheel chair bound paraplegic patients, because greatest pressure is exerted from the body on this area in a sitting position. Even after a series of successful pressure sore treatments, the site is very prone to relapse by the simplest ordinary tasks of everyday life. Therefore, it is crucial to preserve the main pedicle during primary surgery. Various surgical procedures employed to treat pressure sores such as myocutaneous flap and perforator flap have been introduced. After introduction of ischial sore treatment using the inferior gluteal artery perforator (IGAP) has been made, the authors experienced favorable clinical results of patients who have undergone IGAP flap procedure in a three year time period. Methods: A total of 17 patients received IGAP flap surgery in our hospital from January 2003 to May 2006, among which 14 of them being males and 3 females. Surgery was performed on the same site again in 6(35%) patients who had originally relapsed after receiving the conventional method of pressure sore surgery. Patients' average age was 49.4(27-71) years old. Most of the patients were paraplegic(11 cases, 65%) and others were either quadriplegic(4 cases, 23%) or ambulatory(2 cases, 12%). Based on hospital records and clinical photographs, we have attempted to assess the feasibility and practicability of the IGAP flap procedure through comparative analysis of several parameters: size of defective area, treatment modalities, occurrence of relapses, complications, and postoperative treatments. Results: The average follow-up duration of 17 subjects was 25.4 months(5-42 months). All flaps survived without any necrosis. Six cases were relapsed cases from conventional surgical procedures. All of them healed well during our follow-up study. Postoperative complications such as wound dehiscence and fistula developed in some subjects, but all were well healed through secondary treatment. A total of 2 cases relapsed after surgery. Conclusion: The inferior gluteal artery perforator flap is an effective method that can be primarily applied in replacement to the conventional ischial pressure sore reconstructive surgery owing to its many advantages: ability to preserve peripheral muscle tissue, numerous possible flap designs, relatively good durability, and the low donor site morbidity rate.

Objective : This study identified the effect of tailored occupational intervention applied to the elderly with mild dementia using the day care center. Methods : This study applied the single-group experimental design to 29 elderly with mild dementia who use the day care center in B area, and conducted a total of 10 sessions once a week, 60 minutes. Intervention consisted largely of group activities and individual activities, and individual activities were conducted one-on-one with various activities necessary to select occupational goals and achieve the goals through consultation between the elderly with mild dementia and the person in charge. The effects of tailored occupational intervention were confirmed through CERAD, BBS, and GDS. Results : Significant differences were shown in the total score of MMSE-KC, time orientation, attention, constructional praxis delayed recall, and trail making test B in the cognitive function changes, and standing to sitting, standing unsupported with eyes closed of BBS in the physical function changes, and in the GDS score in the depression changes (p<.05). Conclusion : Tailored occupational intervention has been shown to be effective in improving cognitive and physical functions of the elderly with mild dementia and reducing depression. This provided a basis for proposing a tailored occupational intervention as an intervention that can be applied to the elderly with mild dementia.
