  • This study was conducted to develop the interlayer mixture that absorbs the stress between the old concrete pavement and the asphalt overlay pavement layer. The elasticity, the flexibility, the consistency and the impermeability is required for high-elastic Stress Absorbing Interlayer(HSAI) to absorb and disperse the stress that causes the flexural and horizontal movements of the joint and the crack. The HSAI developed from foreign product was satisfied with the design criteria. The specimens using the HSAI showed the significant reduction of the reflective crack compared those not using the HSAI. The significance included that the life of shear failure and horizontal displacement resistance increased 4 times. The life of the share failure increased to 5 times and the horizontal displacement increased to 9 times according to the selection of surface course material which showed the excellence of the HSAI.

  • Purpose : This study investigated the empowerment, burnout, and job satisfaction levels among occupational therapists, and to ascertained the effects of empowerment and burnout on job satisfaction. The study aimed to provide foundational data to help increase job satisfaction among occupational therapists. Methods : We surveyed 180 occupational therapists working in the Jeollabuk-do. The survey included 49 questions covering general characteristics, empowerment, burnout, and job satisfaction. Differences in empowerment, burnout, and job satisfaction levels based on general characteristics were analyzed using independent sample t-tests and one-way ANOVA. We performed multiple regression analyses to ascertain the effects of empowerment and burnout on job satisfaction. Results : The average scores for job satisfaction, burnout, and empowerment were 40.32, 58.40, 41.82, respectively. Job satisfaction according to general characteristics showed statistically significant differences based on the annual income and the most difficult treatment. We found that empowerment factors such as perceived importance of the job confidence in one's abilities, and independence and autonomy in job performance, significantly affected job satisfaction. However, the most significant factor influencing job satisfaction was daily fatigue and stress. Conclusion : Job empowerment and burnout of significantly affected job satisfaction among occupational therapists. Occupational therapists have a effect on the daily lives of their clients through interventions, playing a crucial role for each individual client. Thus, increasing the empowerment and job satisfaction levels of occupational therapists and reducing their burnout levels can help improve the quality of life of the clients and enable occupational therapists to provide high-quality services.

  • Although there have been several attempts to use virtual reality (VR) in the treatment of depression, the results have been inconsistent and existing studies have mostly relied on subjective measures to assess the effectiveness of VR in improving depression. The aim of this study was to investigate the effect of nature experience-based VR intervention on depressive symptoms in a young population using both subjective and objective measurements. The study population included 15 participants who had more than 14 identifiers of the Korean Beck Depression Inventory (K-BDI)-II. Participants received three weeks (four times per week) of VR intervention. The effectiveness of VR was assessed through changes in K-BDI-II scores and depression-related blood biomarkers. Nature experience-based VR intervention led to an approximately 50% reduction of K-BDI-II score (before 25.7±7.7 vs. after 12.5±8.3 (P<0.001)). Of these, loss of pleasure and fatigue showed the largest amount of improvement. However, levels of cortisol, brain-derived neurotrophic factor, and interleukin-6 did not differ from those at baseline. The findings of our pilot study suggest that nature experience-based VR can be a useful adjunctive treatment method for improving depressive symptoms in individuals who have difficulty accessing the real outside natural environment.

  • The purpose of this study is to investigate risk factor found in the patients with stroke in physical therapy. A questionnaire survey was carried out for 130 the patients, who had comparatively alert mentality, hospitalized in kyung hee oriental medical hospital with stroke from January, 1st to May 31st, 1996. Major findings of this stuty were as follows. 1. The stroke patients 67(51.5%)were males and 63(48.5%) femals. The age groups of 50 to 69 years accounted for 67.6% of the total stroke patients are the highest. The job groups of commerce and business of patients 58.5%. The living groups of major citys of the revealed the highest incidence(40.8%). 2. There were 40 patients (30.8 %) who had hemorrhage related condions as the direct cause of their stroke, and 90 patients (69.2 %) who had cerebral infarction with no hemorrhaging as the cause. of the disease that the patients suffered from before their stroke, blood pressure related problems were most numberous 76 patients(58.5%) had such problems. 3. A month before their attack of stroke, were asked what thay thought could become the causes of their strokes. The most frequently mentioned answers were fatigue, drinking too much, and smoking, as chosen by 45 patients(34.6 %). 4. In regarding the relation between stress and stroke, (37.7%), of the surveyed belonged to the most numerous group had of people who said they were not under stress. Yet this group had a large number of parents. And 22.3 % of the surveyed named conflicts among parents, siblings, and relatives. 5. Questions were asked to find out the relationship between complications of stroke and smoking or drinking. It was surprising to see a high rate of attack among the 55.4 % majority who answered that they did not smoke nor drink. 6. To sum up the affect of food on attack of stroke, 42.5% of the people who had a sprcey and salty diet had a higher rate of attack then the group of people with leisurely nature. 7.

  • Objectives: Cornu cervi pantotrichum (CCP) has been widely used in Korean and China, as an anti-fatigue, anti-aging, and tonic agent to enhance the functions of the reproductive and the immune systems. Because CCP has various growth factors that play important roles in the development of hair follicles, we examined whether CCP pharmacopuncture solution (CCPPS) was capable of promoting hair growth in an animal model. Methods: One day after hair depilation, CCPPS were topically applied to the dorsal skin of C57BL/6 mice once a day for 15 days. Hair growth activity was evaluated by using macro- and microscopic observations. Dorsal skin tissues were stained with hematoxylin and eosin. Expressions of bromodeoxyuridine (BrdU), proliferating cell nuclear antigen (PCNA), and fibroblast growth factor (FGF)-7 were examined by using immunohistochemical staining. A reverse transcription polymerase chain reaction (RT-PCR) analysis was also conducted to measure the messenger RNA (mRNA) expression of FGF-7. Results: CCPPS induced more active hair growth than normal saline. Histologic analysis showed enlargement of the dermal papilla, elongation of the hair shaft, and expansion of hair thickness in CCPPS treated mice, indicating that CCPPS effectively induced the development of anagen. CCPPS treatment markedly increased the expressions of BrdU and PCNA in the hair follicles of C57BL/6 mice. In addition, CCPPS up regulated the expression of FGF-7, which plays an important role in the development of hair follicles. Conclusion: These results reveal that CCPPS facilitates hair re-growth by proliferation of hair follicular cells and up-regulation of FGF-7 and suggest that CCPPS can potentially be applied as an alternative treatment for patients with alopecia.

  • In this study, the expression level of estrogen receptor in an ovariectomized rat model was effectively enhanced by MS-10, Cirsium japonicum and Thymus vulgaris extract complex, in a reversible manner. MS-10 plays a positive role in enhancing estrogen activity at low concentrations, leading to improved women's health. In order to determine whether or not MS-10 improves menopausal symptoms clinically, a randomized, double-blinded, and placebo-controlled clinical study was carried out on 62 middle-aged women treated with 500 mg of MS-10 or placebo daily for 12 weeks. Clinical menopausal symptoms were evaluated by Kupperman's index (KI) detecting various menopausal symptoms, including hot flushes, parenthesis, insomnia, nervousness, melancholia, dizziness, fatigue, rheumatic pain, palpitations, formication, and headaches. Total KI score decreased significantly by about 18% upon ingestion of MS-10. Colpoxerosis, a main symptom of menopause, was significantly reduced by about 21% upon ingestion of MS-10 in contrast to placebo. In addition, reduction of insulin-like growth factor-1 with age was improved by over 10% upon ingestion of MS-10, whereas there were no significant difference with placebo. No side effects appeared after treatment with MS-10. Thus, MS-10 can be suggested as a plausible natural substance for improving women's health.

  • Background: Fibromyalgia is a common syndrome of musculoskeletal pain and fatigue. Lacking distinctive histological or laboratory abnormality in diagnosis, it has often been considered a form of "psychogenic rheumatism". Fibromyalgia causes much distress to the affected patients and often frustrates physicians, who are unable to start rational therapy on any logical disease pathology. Methods: Growth hormone is essential for muscular homeostasis. In the present study, the notion that the stage-4 sleep anomaly typically seen in the fibromyalgia syndrome may disrupt growth hormone secretion was tested. Because growth hormone has a very short half-life, serum levels of somatomedin C were measured; somatomedin C is the major mediator of growth hormone's anabolic actions and is a prerequisite for normal muscle homeostasis. Serum levels of somatomedin C using acid-extraction procedure and two-site immunoradiome-tric assay (IRMA) and number of tender points were measured in 27 female patients with fibromyalgia from 40 to 60 years old and 27 healthy controls. Results: There were no differences in the concentration of somatomedin C between fibromyalgia patients and controls ($mean{\pm}SD$: $178.3{\pm}75.5$ ng/ml versus $166.3{\pm}76.6$ ng/ml; p=0.55). And there were no correlations between number of tender point and serum somatomedin C level by linear regression analysis. Conclusions: These findings did not support that there is a distinctive disruption of the growth hormone-somatomedin C neuroendocrine axis in a fibromyalgia syndrome. But we can not discard the hypothesis that disturbed sleep predispose to muscle pain.
