The use of natural environments to change lifestyle and health has been long recognized. In particular, forests, trees, and open space have been shown to promote mental health. In this study, we examined the effectiveness of the structured psychotherapeutic program using forest environment ("forest activity program") to improve the symptoms of nine patients with Major Depressive Disorder (MDD) who were taking variable doses of antidepressants. We assessed the depressive symptoms, quality of life, and autonomic nerve regulation among the MDD patients. Hamilton Rating Scales for Depression (HRSD) scores significantly decreased after the forest therapy (13.56 vs. 5.56, p=0.003), and some subscores of Short Form 36 health survey questionnaire (SF-36) and heart rhythm coherence are improved as well. Combined with antidepressant pharmacotherapy, the structured psychotherapeutic program using forest environment showed an improved health status for MDD patients and thus has potential as an adjuvant treatment for MDD, especially for rehabilitation and relapse prevention.

This is a study of decrease in both stump pain and unidentified complaints after removal of neuroma on an amputated left thigh. The patient was a 44 year old woman who received an operation after a motorcycle accident 20th of March, 1991. She started a rehabilitation program in early June of the same year. How ever the patient complained of a squeezing pain on the amputated area. This symptom became more severe after the removal of the nails in September. The pain was perceived as a mental problem and the patient was released from the previous hospital. The pain continued and on the 9th of March, 1992, the patient was introduced to our pain clinic. The patient complained about the cold sensation and pressure pain of the amputated area at the beginning. Later she also expressed various unidentified complaints. No improvement resulted after conducting an epidural block and a lumbar sympathetic ganglion block. MMPI test showed psychological instability. Local injection showed some positive effects, which led to considerations concerning the possibility of neuroma. After confirming the existence of neuroma through CT and MRI, neuromectomy was performed. After the removal of neuroma, the unidentified complaints as well as the stump pain decreased.

In this paper, it has been studied about the CRCO to maintain or rehabilitate the aged JCP. The CRCO and JCO was constructed at useless section of Seo-Hae-Ahn express highway in South Korea. The performance evaluation was conducted. Especially, it was focused on the roll of longitudinal reinforced steels inserted into the CRCO. On crack survey results from field construction section, the reflection cracks at joint of the existing pavement occurred in CRCO. However, due to the constraints of longitudinal reinforced steels, crack width was small. Total crack length and quantity in the CRCO more than that in the JCO. And crack spacing in the CRCO was narrower than it in the CRCP. Through the bonding strength test results, if the cold milling and cleaning as well as surface treatment is applied, there will be no debonding problem at interlayer in the early age. From analysis of the horizontal behavior at the joint, the longitudinal reinforced steels constrained crack width which became wider than initial state over time. Also, that steel in the CRCO reduced the horizontal movement due to temperature variation(4 times than that in the JCO). But, if interface is debonded, the roll decreased. Vertical VWG data showed that CRCO did not occur debonding problem at steel location, but there was some problem in JCO. It was confirmed by field coring. The tensile strain appeared in the CRCO, But the compressive strain occurred in the JCO in early age. Through the FWD test result, deflection in the CRCO was less than that in the JCO. And K value in the CRCO was greater than it in the JCO.

The purpose of this study was to evaluate the effects of insole-equipped ankle-foot-orthoses (AFO) on gait. 10 healthy males who had no history of injury in the lower extremity participated in this study as the subjects. The foot of each subject was first scanned, and the insole fit to the plantar was made using BDI-PCO(Pedcad Gmbh, Germany). The subject then was made to walk on a treadmill under four experimental conditions: 1) normal walking, 2) walking wearing AFO, 3) walking wearing AFO equipped with the insole, 4) walking wearing pneumatic-ankle-foot-orthosis (pAFO) equipped with the insole. During walking, foot pressure data such as maximum force, contacting area, peak pressure, and mean pressure was collected using Pedar-X system (Novel Gmbh, Germany) and EMG activity of lower limb muscles such as gastrocnemius medial head, gastrocnemius lateral head, and soleus was recorded using MP150 EMG module (BIOPAC System Inc., USA). Collected data was then analyzed using paired t-test in order to investigate the effects of the insole. As a result of the analysis, when insole was equipped, overall contacting area was increased while both the highest peak pressure and the mean pressure were significantly decreased, and EMG activity of the lower limb muscles was decreased. On the contrary, the cases of wearing AFO showed the decreased contacting area and the increased pressures. Therefore, the AFO equipped with a proper insole fit well to the foot can help comfortable walking by spreading the pressure over the entire plantar.

The purpose of this study was to examined whether high voltage pulsed current stimulation(HVPCS) enhances the migration and proliferation of fibroblasts from tendon biopsies to provides evidence that the cellular activities of fibroblast are enhanced by HVPCS. Flexor digitorum profundus tendon of chickens were excised, biopsied and cultured in M199 medium for a day. The biopsies through which a cathodal HVPC with 100 pps, 50 V for 30 minutes was passed in medium. A day after treatment, the biopsies embedded in fibrin clot were covered by the addition of 1ml of M199 medium to the well, and placed in the $CO_2$ incubator for the duration of the experiment. The migration distance of cells from tendon biopsies were measured at 6 days after treatment, and proliferation of cells from tendon biopsies were measured at 7 days after treatment. The migration distance of cells from tendon biopsies in the HVPCS group demonstrated significantly greater than the shame treated control group (t=-2.675, p<0.05). Also HVPCS had significantly increased optical density of fibroblasts from tendon biopsies (t=-2.136, p<0.05). These results indicate that the HVPCS with 100pps, 50V for 30minutes enhanced either the migration and proliferation of fibroblast from tendon biopsies. These results supposed that the HVPCS activates cellular responses in fibroblasts from tendon biopsies. This suggests that enhanced the migration and proliferation of fibroblast by HVPCS may be one of the mechanism involved in tendon healing.

Blood flow restriction(BFR) exercise is defined as low and short lengthexercise with pneumatic pressure belts at the top of the limbs. This study was conducted to investigate the effects of walking exercise with BFR on body composition, growth hormone, and muscle damage markers in obese women. Eleven obese women(> BMI 25kg/m2&> body fat 30%) wore pneumatic pressure belts at both femurs and performed walking exercise twice per day, 3days/wk for 4 week (walking 2min; resting 1min). Body weight, BMI and body fat significantly decreased after exercise(p<0.05), while% body fat was slightly decreased after exercise, although this difference was not significant. Growth hormones increased slightly after exercise, although not significantly. Muscle damage markers (CK(p<0.05), LDH(p<0.05) and K+(p<0.01 increased significantly after exercise, but Mb was did not change significantly. These results suggest that 4-weeks ofblood flow restriction exercisecould be used to prevent and treat obesity and related chronic diseases, as well as metabolic syndrome. Moreover, the effects were similar to those observed in response to high intensity resistance programs, despite the short period for which BFR were conducted.

Swallowing disorders that can affect nutrient intakes and quality of life are commonly shown among the elderly as well as patients with neurogenic disorder. This study verifies the reliability and validity of the Swallowing Disturbance Questionnaire (SDQ), a subjective swallowing disability assessment tool, modified for Koreans' eating habit and cultural sentiment, against 105 stroke patients, in order to help identify early swallowing problems of the elderly. Reliability of internal consistency in the Korean version of SDQ is .601, test-retest reliability is .97, and concurrent validity is .956. Based on 8 points of cut-off score, 46.8% of sensitivity and 81.6% of specificity. Comparing the results of video fluoroscopic study (VFSS), an objective swallowing disorder test with those of Korean version of SDQ, negative predictive value (NPV) and positive predictive value (PPV) was shown as 81% and 53%. The Korean version of SDQ is expected to be a useful testing tool to discriminate swallowing disorders in stroke patients. It has great clinical significance in that swallowing difficulties shown by subjects can be sorted out to request a diagnostic assessment before clinical evaluation by a rehabilitation therapist or ruling out unnecessary exposure to additional tests by accurately identifying stroke patients without swallowing problems.

Doellingeria scabra Thunb. (syn. Aster scaber Thunb.), a perennial herb in the family Asteraceae, is frequently found in the wild mountain regions of Korea. This aim of this work was to measure the characteristics of patchiness of D. scabra in a local population on Mt. Maebong in Taeback-ci, Gangwon-do. The spatial distribution pattern of this species was estimated by analyzing ecological data by methods including the index of dispersion, Lloyd's mean crowding, and Morisita's index. The mean population density of the D. scabra population was 2.94. The D. scabra individuals were uniformly or randomly distributed in small-scale plots and were aggregately distributed in two large-scale plots ($16{\times}32m^2$ and $32{\times}32m^2$). The mean crowding ($M^*$) was 0.916. The mean patchiness index (PAI) was 0.796. Morisita's coefficient tended to decrease the density of the population as the plot size increased. The expected value of Eberhardt's index ($I_E$) in the local population was 2.623. Moran's I of D. scabra significantly differed from the expected value in 6 of 8 cases (75.0%). The first five classes were positive, with four showing statistical significance, indicating similarity among individuals in the first four distance classes (I-IV, 8 m), The results presented here could provide a theoretical basis for the conservation of D. scabra (Korean: chamchwi) and for the rehabilitation and sustainable management of forest ecosystems on Mt. Maebong, as well as on other mountains.

Objective : This study aimed to identify the characteristics of hand function according to age and sex in older adults. Methods : This study included 103 healthy adults aged ${\geq}60$ years. The Korean version of TEMPA was used to assess hand function and a Jamar dynamometer and pinch gauge were used to assess hand and pinch strength in all participants. Results : The results of hand function assessment showed that speed of task execution (mean = 121.32 s, SD = 18.07 s in subjects aged 60-69; mean = 144.97 s, SD = 28.43 s in subjects aged 70-79; and mean = 160.93 s, SD = 38.33 s in subjects aged ${\geq}80$, p < .001) and fine movement (mean score = -.14, SD = .40 in subjects aged 60-69; mean score = -.63, SD = 1.07 in subjects aged 70-79; and mean score = -.57, SD = .65 in subjects aged ${\geq}80$, p = .01) decreased significantly with age. The male group showed better speed of task execution (mean = 133.54, SD = 22.83 in males vs. mean = 150.55, SD = 39.89 in females, p < .01) and fine movement (mean score = -.16, SD = .37 in males vs. mean score = -.46, SD = .58 in females, p < .01) than the female group. Hand strength also decreased significantly with age (p < .05, to p < .001). Conclusion : Occupational therapists should be aware of the decline in hand function (especially speed of task execution and fine movement) and strength in older adults, as well as the need to provide interventions to treat this decline.
