The need for forest therapy programs has been increasing. For more effective forest healing, it is necessary to identify the characteristics of participants and develop and operate more targeted and differentiated forest therapy programs accordingly. In this study, the relationships between MBTI (Myers-Briggs Type Indicator) personality types and the relationship between the temperaments of MBTI and the preference for the forest therapy programs were analyzed respectively in pursuit of the basic data required for the effective development and operation of forest healing on the basis of individual characteristics. The survey on the forest therapy program and MBTI personality tests were conducted for 245 normal adults. Using the SPSS 21.0 program analysis, data were analyzed by Analysis of variance (ANOVA) to obtain the difference of preference on the forest therapy program according to the personality type. The Extraversion(E)-Introversion(I) types showed differences in technique-based breathing exercises, walking in the forest(wearing shoes), laughter therapy in the forest, viewing the forest, forest bathing, wind bathing and sun bathing. And the Sensing(S)-iNtuition (N) types had marked differences in listening to the sound of water flowing, drinking herbal tea and sleeping in the forest. The Thinking (T) -Feeling (F) types marked differences in soaking hands and feet in water and sleeping in the forest. The Judging (J)-Perceiving (P) types had differences in vision quest and viewing the forest, respectively, in statistics. Depending on the temperament of the character, there were statistically significant differences in preferences such as drinking herbal tea, eating natural food, sleeping in the forest, viewing the forest and listening to the forest commentary. The results of this study are expected to be used as a basis for forest healing program development and operation.

Objective : The purposes of this study was to analyze the locomotive movement of forelimbs according to changes in velocities in the quadruped cadence of horses. Methods : Horses selected as subjects consisted of Jeju pony horses (heights of withers: $1.23{\pm}0.51$). Two camcorders (HDR-HC7/HDV 1080i, Sony Corp, Japan) were used to capture the movement of the horses' forelimbs at a rate of 60 frames/sec. Additionally, raw data was collected from Kwon3D XP motion analysis package ver 4.0 program (Visol, Korea) with DARTFISH (DFKREA., Korea) video software solution. The variables analyzed consisted of 1 step lengths, 1 stride lengths, stance time, swing time, 1 stride time, velocity while walking, and trot of the horses. A two-way ANOVA and paired t-test of the variables by velocity and phase were treated at .05 level of significant difference, statistically. Results : The time elapsed of walk(stance: 0.63 sec[63.86%], swing: 0.35 sec[36.14%], 1 stride time: 0.99 sec respectively) showed significant difference with more delay than that of trot(stance: 0.29 sec[45.73%], swing: 0.34 sec[54.27% ], 1 stride time: 0.63 sec respectively), and also showed significant difference at trot in interaction (stance time>tort swing>walk swing>walk stance). The 1 step lengths and stride lengths in trot showed significant difference with longer than that of walk. Velocity of Trot showed significant difference statistically with higher than that of walk Conclusion : The horses' velocity during 1 step lengths and 1 stride lengths showed a proportional relationship, but the correlation between the horses' velocity and stance time showed a negative relationship during the quadruped cadence.

This study was to evaluate opportunities for the commercialization of smart insole. smart technology is evolving to Insole. Pressure-sensitive sensor or an acceleration sensor is applied to create a balance of the feet and body, is also evolving for entertainment (sports, entertainment, etc.) and health care. Moreover, smart insole can fix an incorrect walking habit by sending a weight value measured by the sensor on a smartphone and during the movement, smart insole helps to correct body balance by measuring the center of gravity moving condition. However, smart tendency of the insole has yet to create a clear boundary in the entertainment and healthcare markets. This is because the fitness band, smart socks, smart shoes can also replace the benefits of a smart insole. Interestingly, the business opportunities are appearing more frequently in health care solution service of electrocardiogram, body temperature, blood pressure, etc., rather than smart devices.

Objective: The aim of this research was to investigate the effects of functional electrical stimulation (FES) applied to the gluteus medius (Gm) and tibialis anterior (TA) during stair climbing in persons with stroke compared to FES applied to the TA only during stair climbing, and during stair climbing without FES in persons with stroke. Design: Cross-sectional study. Methods: Twenty subjects with stroke participated in this study. Subjects were included if: 1) they were diagnosed as stroke at least 6 months before; 2) had Mini Mental State Examination- Korean score of 24 or higher; 3) were able to climb a flight of 10 stairs independently (with or without walking aid). The patients walked 10 stairs 3 times with FES applied to the Gm and TA, only TA, or no FES. There was a 1-minute rest period between each bout. The assessments were made using the Timed Up & Down Test and the Wii Balance Board. Results: Stair climbing with FES applied to the Gm and TA was significantly faster than stair climbing with FES applied to the TA only and without FES (p<0.05). Stair climbing with FES applied to the Gm and TA exhibited significantly greater sway velocity than stair climbing without FES (p<0.05). However, maximal sway distances were not significantly different between groups. Conclusions: Stair climbing with FES applied to the Gm and TA can be an important component of a rehabilitation program for improving stair climbing ability in persons with stroke.

Purpose: The purpose of this study was to assess the level of activities of daily living (ADL) in a group of community dwelling elderly. Methods: The subjects were 100 low-income elderly registered in a public health center. The data were analyzed using the SPSS/PC program. Results: The results were as follows: 1. The basic ADLs of the subjects were scored at 7 levels, and the mean score was 6.24 out of 7 points. The subjects did not necessarily require help from others, but might have needed more times or instrumental assists to perform ADLs. The lowest ADL score was reported on walking up to the stairs (5.05), for which the subjects did not need physical assistance, but needed a certain degree of supervision. The highest score was reported on self eating (6.74), followed by bowel management (6.60). 2. The mean IADL score of the subjects was 1.77 out of 4 points. indicating that the subjects were very independent in performing IADLs, without help from others. 3. In relation to general characteristics, the level of ADLs of the subjects was significantly different by age (F=6.65, P=.000), main activities (F=6.36, P=.001), perceived health status (P=4.66, P=.012), educational background (F=4.64, P=.03), marital status(F=4.62, P=.005), and major household income (F=4.15, P=.002). 4. The subjects' level of IADLs in relation to their general characteristics was significantly different by perceived health status (F=8.08, P=.001), major activities (F=7.33, P=.000), age (F=6.18, P=.000), family context (F=3.53, P=.018), religion (F=3.10, P=.019), marital status(F=2.62, P=.055), and major household income (F=2.31, P=.049).

The purpose of this study is to clarify the correlation between the degree of patients daily activities and that of a sense and social support of families. This study covers families of 252 patients under home health nursing care at 6 University Hospitals during the period of March to May. 1999. The data were collected by using three different questionnaires. Data were analysed by utilizing SAS program such as frequency. average. percentage. t-test. ANOVA. Scheffe test and Pearson Correlation Coefficient. The results were as follows: 1. The average score of patients' daily living activity was $2.36\pm0.67$. $97.2\%$ patients turned out to be. in part. dependent on their family's care. $66.5\%$ of the patients were still dependent on their families in walking: $66.3\%$ In bathing: and $61.0\%$ in using toilet. 2. The average score burdened family caregivers had felt was 2.25 in 4 full point which can be interpreted as average. Among the six burden dimensions. time was said to be the No. 1 burden-yielding factor. When it comes to the characteristics of patients. there were tendencies for patients with lower incomes residing in communal housing. with cerebrovasculal diseases and with higher score of daily living activity to show a higher burden scores. 3. The average score of social support was 2.49 in 5 point. which represents a average score. Among other items. the opportunity of social integration was 2.66. topping the list whereas a chance of upbringing was starkly low at 2.42. The higher scores of social support were shown in cases where the caregiver was male spouse. total care giving duration exceeded 25 months and malignant patients daily living activity scores were low. 4. The score of patients daily activity was positively correlated to the degree of the family burden (r=0.1942). Data indicates there was direct correlation between daily living activity and burden of time consuming, self-improving and physical impairment. 5. The score of the patients daily living was negatively correlated to the social support (r=0.3414), As a whole. there was negative correlation between social support and the formation of intimacy and self-confidence.

In order to grasp the occupational add social characteristics of the onset of lumbago among elementary and high school teachers, 423 elementary and high school teachers were taken as subjects of study through questionaires. The following are the results of the study which were analyzed through data, conducted for one month in the City of Taegu, between Jun. 90, and Jul. 20 of 1993: 1. the incidence of lumbago of the entire teachers was $75.2\%$, with the elementary school teacher$(81.9\%)$ higher than high school teacher$(70.6\%)$. 2. In the relationship between the characteristics of job and lumbago. characteristics of teaching, monthly income, chores and satisfaction with job did not show significance, but weekly teaching hours, mental stress and the degree of comfort of chair reflected significantly(p<0.01). 3. In social relationship, personal nature, sleeping hours and place, smoking and drinking did not hold significance, but daily average walking hours, posture during sleep, general health conidition(p<0.01) and daily average riding hours and regular exercise(p<0.05) etc. showed significant relationships. 4. In the sistuation of lumbago of the teacher groups, no significant differences wee found in the cause of lumbago, duration of lumbago, sick leaves and recognigion of lumbago, but it was contrary in the treatment of lumbago(p<0.01). Based on the above results, lumbago is closely related to occupational and social factors, the prevention and treatment can be diversified based on occupation and environment. Consequently, regular educational program is considered imperative mainly on prevention of lumbago by putting aside time for such purpose.

PURPOSE: This study examined the muscle activity while stepping over obstacles with various heights and widths to provide basic data for training and preventing falls. METHODS: Fifteen normal young adults (seven males and eight females) were recruited. The participants walked on a 5m walkway with six obstacles. The heights of obstacles were 0%, 10%, and 40% of the subject's leg length, and the width of the obstacles was 7cm and 14cm. The participants traversed the course twice per obstacle. The muscle activities of the soleus, tibialis anterior (TA), vastus medialis (VM), and vastus lateralis (VL) were measured using surface electromyography. A Mann-Whitney test and Kruskal-Wallis test were used to examine the differences between obstacles. RESULTS: The muscle activities of the VL and the soleus of the stance leg and lead leg after crossing over the obstacles increased with increasing width, and there were significant differences in muscle activities between obstacle width (p<.05) except for the muscle activity of TA of the stance leg after crossing over the obstacles. A significant difference in muscle activities was observed according to the height of the obstacles with 14 cm (p<.05) except for the muscle activity of the VL, soleus of the leading leg, and TA of the stance leg CONCLUSION: The role of the VL and Soleus increased with increasing obstacle width, and the overall muscle activities of the lower extremities increased with increasing obstacle height. These results can be used to suggest a program to prevent falls.

PURPOSE: The purpose of this study was to determine if virtual reality-based exercise was effective in balance, gait, and falls efficacy in patients with Parkinson's disease (PD). METHODS: Thirty patients with PD were assigned randomly to the experimental (n=15) or control groups (n=15). The experimental group performed virtual reality-based exercise and the control group underwent conventional physical therapy for 30minutes, five times per week for four weeks. A force platform system, the Korean version of the Berg Balance Scale (K-BBS), the six-minute walking test (6MWT), and the Korean Version of the Falls Efficacy Scale (K-FES) were used to evaluate balance, gait, and falls efficacy. Wilcoxon signed-rank test and Mann-Whitney U test were used to examine the within- and between-group differences after training, respectively. RESULTS: Changes in the K-BBS score (p<.001) and fall efficacy (p<.01), following the intervention were significantly greater in the experimental group than in the control group whereas significant group difference were not observed for the anterior-posterior and mediolateral postural sway lengths. The change in the ground reaction force (p<.001) and 6MWT values (p<.05) were significantly greater after intervention in patients in the experimental group than in the control group, whereas a significant group difference was not observed for the step and stride lengths. CONCLUSION: This study indicates that virtual reality-based exercise is an effective intervention for improving balance, gait, and fall efficacy in patients with PD.

This paper presents the mobile phone case for self-power generation and recharge for emergency calls or text messages at the discharge of a battery. If the user shakes his smart phone case, the interaction of electromagnetic coil and permanent magnet in an electric generator produces electric energy, which charges the lithium-ion battery. This enables the user to give a few calls or text messages. In addition, the vibration energy from humans walking at a frequency of 2 ~ 3Hz charges the battery. The electric generator was simulated using MAXWELL, a commercial electromagnetic analysis program, to analyze the electric power generation. Finally a prototype of the mobile phone case for self-power generation was built based on the analysis and its performance was verified.
