Purpose: This study was conducted to ascertain the effectiveness of forest healing therapy by analyzing researches on forest healing therapy applied to Korean adults and to confirm that forest healing therapy can be used as a therapeutic intervention program for elderly nursing or rehabilitation nursing. Methods: We searched 972 research papers on forest therapy applied to Korean adults. We reviewed appropriate 25 research papers with experimental design among them in the final analysis. Results: Forest healing therapy had physiological and psychosocial effects. First of all, it showed physiological effects to reduce stress index such as heart rate variation. Forest therapy also improved melatonin level in blood of middle-aged women with menopause and increased alpha wave in electroencephalogram and decreased lipid level and superoxide dismutase in blood. Second, forest healing therapy showed psychosocial effects to reduce depression and to improve mental health. But the effects appeared differently depending on the implementing type, period of forest healing therapy, and the professionalism of therapists. Therefore, if forest healing therapy would be applied to nursing, it should be based on its key principle, in other words, its principle of action-interaction-response of forest healing therapy. Conclusion: The results of this study could be used to develop a forest healing program as an intervention of nursing.

Purpose: The goal of this study was to investigate the histomorphometric characteristics of the healing process of microcracks in the cortical bone after the installation of mini-implants (MIs). Methods: Self-drilling MIs were inserted into the tibial diaphysis of twelve adult male New Zealand rabbits. Four MIs per rabbit were placed randomly. The animals were divided into four groups according to the length of the healing period: group A was sacrificed immediately, group B was sacrificed after one week, group C was sacrificed after two weeks, and group D was sacrificed after four weeks. Cortical bone thickness was measured using micro-computed tomography, and histomorphometric analyses of the cumulative length of the microcracks (CLCr) and the total number of microcracks (NCr) were performed using hematoxylin and eosin staining. Results: The microcracks were radially and concentrically aligned in the peri-MI bone. The CLCr decreased significantly one week after the surgery, mainly due to healing of the concentrically aligned microcracks. The CLCr showed another significant decrease from two weeks after the surgery to four weeks after the surgery, mainly reflecting healing of the radially aligned microcracks. A statistically significant decrease in the NCr occurred as the microcracks healed from zero weeks to two weeks. However, no significant difference in the NCr was found between groups C and D. Conclusions: In order to improve the primary stability of MIs, delayed loading and a healing period of a certain length are recommended to ensure the optimal healing of microcracks and bone remodeling.

This study investigated the effects of changes to the pulsation factor of pulsed direct currents on wound healing. Patients with a pressure ulcer at a care hospital for the elderly were randomly divided into three groups: Group 1 involved the application of $100{\mu}s$ in pulse duration, 10 ms in pulse period, 100 pps in a pulsation factor, 15 mA in pulse amplitude, and polarity red+ by using pulsed direct currents; Group 2 involved a change of pulse period to 8 ms; and Group 3 received general wound management. Although there were no statistically significant differences in the changing stages of pressure ulcers among the groups, all the groups dropped in numerical stages. In the two groups to which pulsed direct currents were applied, there was a statistically significant reduction in the stages of pressure ulcers from the initial assessment to the 12-week assessment (p<.05). Even though there were no statistically significant differences in changes to the area of pressure ulcers among the groups, a statistically significant decrease was found in pulsed direct current group 2 whose pulse period was shortened (p<.05). There was no difference in the healing rate of pressure ulcers among the groups, but it made a numerical increase in pulsed direct current group 1 and group 2 and a numerical decrease in group 3. There were no significant differences in the characteristics of those who had a full recovery among the groups. Those findings indicate that pulsed direct currents have positive effects on the wound healing of patients with a pressure ulcer and that a treatment with pulsed direct currents whose pulsation factor is raised by reducing the pulse duration is especially effective.

The purpose of this paper was to observe the influence of Ga-As semiconductor-low power generating laser on she appearance and actions of tenascin, extracellular matrix, as healing process of intentional wound on the experimental animals is taking place. 35 rabbits were divided into control and experimental group. ; and on each, 3mm-long and 2mm-deep, surgical wounds were created on buccal oral mucosa and thoracodorsal portion of skin. Ga-As laser was applied to the experimental group starting a day of the day the wounds were created , the laser was applied for 5 minutes every other day. Tissue samples were taken after the 2, 4, 7, 10, and 14 days after wound formation. Then tile healing process of experimental and control groups were observed and compared, using light microscope. Afterwards, the samples were immunohistochemical stained and again observed tenascin by quantitative measuring. The following results were obtained : 1. Tenascin was observed prevalently on epithelial cells, border area of dermis, and interstitial matrix between connective tissue layers in both experimental and control groups. 2. In oral mucosa, the experimental group showed significant increase in the appearance of tenascin after 4 days compared to the control group, but after 10 days, it decreased to a point which is even less than the control group. 3. In the skin samples, the pattern of appearance of tenascin was the same in both groups, but there was some difference concerning when the peak period was shown, In the experimental group, the peak period of tenascin expression was the 7 days after wound formation in epithelium and connective tissue. In the control group, the peak period was 10 days after. 4. In both the experimental and control groups, tenascin first appeared in the epithelium near the wound area and submucosa, and then spread on the underlying connective tissue. In conclusion, appearance of tenascin is closely related to regeneration of epithelium and development of granulation tissue : therefore, low power laser, which fastnes appearance of tenascin, is sure to faciltate healing process of oral mucosa.

The negative memories which come from tragic events such as war, terror or various conflicts in modern cities have been threatening the mental health of city-dwellers. This thesis focuses on 'healing public space' that will help recover the life of city-dwellers who sustain various trauma. For this, the author investigated the significant memorial space through 1980-2010 from site visits, interviews, and related theses and books and then extracted necessary information from each period. This thesis aims to find the changes of the memorial concepts and visitor's reaction for last 30years. 1)1980-: Healing concept and visitor's positive response 2)1990-: Healing by emotional experience approaches to the memorial museum such as narrative approach, exhibition media using 5senses, interactive display and preserving trace, 3)early 2000-: Healing by architectural experience 4)2002-: present: Healing projects by various programs. Steady advances in memorial design for healing trauma are due to the efforts for emotional design approach to eeply move the visitors and the efforts have to be continued. The study emphasize the importance of attracting eople by experimental, emotional design contents not just by aesthetic and functional public design ideas.

Delayed healing associated with distal limb wounds is highly challenging in equine clinical practice. This study aimed to evaluate healing rates between chronic non-granulating wounds of horse distal limbs that were treated with maltodextrin/ascorbic acid gel alone or in combination with povidone-iodine 1% solution and those treated with povidone-iodine 1% only throughout the study period (35 days) in clinical settings. The study was conducted on 18 adult horses (3-15 years old). Based on the treatment regimen utilized, the horses were divided into three groups (n = 6), with each group having a similar mean wound area. The percentages of wound contraction, epithelialization, and overall wound healing were determined weekly for each wound. By the end of the study, the total wound healing percentage was significantly increased between the study groups (p < 0.05). The use of maltodextrin/ascorbic acid gel resulted in considerable wound contraction, rapid epithelialization, and complication-free wound healing. Based on the findings of this study, maltodextrin/ascorbic acid gel, independently or in combination with a 1% povidone-iodine solution, might be applied as a safe and effective wound healing promoting agent in horses with chronic non-granulating wounds.

This research investigates the possibility of using the postural sway of patients as a reference for measruing the progress of the disease and healing of patients who received total hip replacement; the progress of the disease by X-ray pictures, the pain felt by the patients, and the difficulties encountered in moving the joints. The measurements on the force platform were taken during a 25 second period standing on both feet and during a 5 second period standing on one foot with both eyes open. The result of the research showed that the trace and area of the overall length of postural sway was a good indicator which represented the healing progress of the patients who received total hip replacement, and the weakening of the muscles and the recovery process for 3 or 4 month after receiving the operation, which did not appear on X-ray pictures, were exhibited on the postural sway. Finally, standing on a single foot represented the healing progress much better than standing on both feet.

Bone remodeling results from the combined process of bone resorption and new bone formation which is regulated in part by some of Dexamethasone related proliferation & mineralization of cultured bone cell and polypeptide growth factors such as platelet derived growth factor(PDGF), which has been known to be an important local regulator of bone cell activity and participate in normal bone remodeling. To evaluate the effects of Dex and PDGF on bony healing of calvarial defect in rats, 10 ng/ml PDGF were applied on P group and 10 ng/ml PDGF and $10^7$ M Dex were applied PD group. 4 rats in each group were sacrificed at 7, 14. 21 days after operation respectively, and the tissue blocks were prepared for light microscope with H-E for evaluation of overall healing, with TRAP(tartrate resistant acid phosphatase) for evaluation of osteoclastic activity and with immunohistochemical staining for macrophages. The results were as follows : 1. In all group, healing aspects were progressed from 7 days to 21 days in soft and bony tissue, but complete repair were not observed in bony defect 2. PDGF and control group were showed similar bony healing aspect , but bony healing in combination of PDGF-BB and Dex were observed slower aspect compared to PDGF and control group from early healing times. 3. There were no significant difference on activities of osteoclast and macrophages in bony healing between control and experimental group In conclusion, PDGF were not influenced on bony healing of defect and combination of PDGF-BB and Dex were showed slower healing through early healing times. it was considered that Dex compared to PDGF did influenced on early hone formation factors in healing period

School age is the period when forms the most of physical, spiritual and behavioral developmental characteristics. And those are kept for lifetime. Since each of developmental characteristics is created through the interaction with physical environment, the learning space which is children's main playground should be designed as healing environment. Therefor, the purpose of this research is to find the healing environmental elements for learning space that help school children's developmental characteristics. For that, we researched the physical, spiritual and behavioral developmental characteristics of school children. And we found the healing environmental characteristics for learning space along with each developmental characteristics, by the analysis of Herman Hertzberger's elementary schools' classroom environment.
