The purpose of this study was to evaluate clinical changes in graft size after treatment with strip gingival autograft in human. 57 premolar teeth in 27 patients having the following mucogingival problems were selected. The width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth were measured at the initial examination, 2, 12 and 24 weeks following the strip gingival autograft and free gingival autograft. The change of width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth according to healing process in both graft procedures was statistically analyzed by repeated measure ANOVA test and independent t-test using SPSS program. The results were as follows : 1. The change of keratinized gingiva in both graft procedures was increased significantly at 24 weeks post-op. 2. The clinical sulcus depth exhibited no marked changes throughout the entire investigation in both graft procedures. 3. No dimensional variation was seen in graft size in both graft procedures. 4. Shrinkage did not differ significantly in both graft procedures. From the day of grafting to 24 weeks after surgery the percentages of shrinkage were : strip gingival autograft 28% and free gingival autograft 29%.

Purpose: This study aimed to evaluate the effects of sociodrama on mothers of adolescents receiving special education at school. Methods: The participants were 30 mothers of adolescents with autism and intellectual, physical, emotional, and behavioral disability (experimental group=8, control group=16, 4 excluded). Sociodrama was conducted over 6 weeks (6 sessions). Data were collected using a mixed method. A constructed questionnaire on parenting stress, depression, and parenting self-efficacy was distributed before and after the intervention. A focus group interview was conducted subsequently. Data were collected from May to June 2016 and analyzed using Wilcoxon-Mann-Whitney test and a content analysis. Results: The intervention group showed significant changes in parenting stress (Z=-2.34, p=.019), depression (Z=-.3.46 p=.001), and parenting self-efficacy (Z=-2.82, p=.029) compared with the control group. Results of the qualitative analysis exhibited two themes, namely "changes" and "healing and challenges," which were divided into 4 categories and 9 sub-categories. Conclusion: Sociodrama was effective in reducing the level of parenting stress and depression, and increased the level of parenting self-efficacy in participants. Sociodrama can be recommended as an intervention program for parents raising adolescents receiving special education.

Rehabilitation treatments after orthopedic surgery promote postoperative healing in humans. In veterinary medicine, there is increased interest in rehabilitation treatments because they are potentially beneficial to animals in the post-operation period. This study examined the effectiveness of rehabilitation treatment in dogs that underwent orthopedic surgeries, including femoral head & neck ostectomy (FHNO) and medial patellar luxation treatment (MPLT). The group that received the rehabilitation treatment after FHNO (1.88 weeks) showed a significantly shorter recovery length of 6.62 weeks compared to those that did not receive the treatment (8.50 weeks). The other group that received the rehabilitation treatment after MPLT (4.38 weeks) showed a significantly shorter recovery length of 5.01 weeks compared to those that did not receive the treatment (9.39 weeks). For the qualitative evaluation, the types and frequencies of rehabilitation treatments were monitored. The rehabilitation programs used frequently were heat therapy, laser therapy, passive range of motion, exercise therapy, and aquatic therapy. A standard rehabilitation program after hindlimb surgery was suggested based on the quantitative and qualitative investigation. The results add additional evidence that showed the beneficial effects of rehabilitation treatments in dogs.

This study was a systematic review and meta-analysis designed to investigate the effects of physical activity programs on sleep among community-dwelling elders in Korea. Based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, research articles published until November 20, 2016 were systematically analyzed and a total of seven papers were finally selected. Meta-analysis of the studies was conducted using Comprehensive Meta-Analysis 3.0. The results showed that the total effect of the physical activity program for elderly people, such as healing yoga, aerobic dance, aquarobics, Korean dance, BeHas exercise, exercise programs and Tai Chi exercise on sleep was Hedges' g=0.577 (95% CI: 0.337-0.817) The BeHas exercise program had the largest effect size on elderly's sleep, with a Hedges' g=0.758 (95% CI: 0.248-1.267). This was followed by the Tai Chi exercise program (Hedges' g=0.697; 95% CI: 0.071-1.324) and the exercise program (Hedges' g=0.650; 95% CI: 0.141-1.159). Therefore, when applying nursing interventions to improve quality of sleep of elderly people living in the community, it would be helpful to apply the BeHas exercise and the Tai Chi exercise, which have a positive effect on sleep of the elderly.

Platycodon grandiflorum A. De Candolle (Korean name, ‘Doraji’) is a perennial plant containing various triterpenoid saponins. The roots of this plant have traditionally been used as a food material in Korea. Here, we prepared a fermented P. grandiflorum extract (PG). Although it was previously reported that P. grandiflorum A. extract has a variety of physiological functionalities, including anti-inflammatory and anti-oxidant activities, little is known about its vascular functions. In this study, we executed a series of experiments to identify the effect of PG on endothelial cells. PG at a high concentration (100 μg/ml) was found to induce cell detachment, whereas PG at a low concentration (0.1 μg/ml) appeared to promote cell proliferation and migration in bovine aortic endothelial cells. The cell detachment induced by the high concentration was not associated with cell death, such as apoptosis, necrosis, and autophagy. In addition, we found that PG at the high concentration formed a small vesicular structure called an endothelial microparticle (EMP). The EMP was prepared by centrifugal fractionation and determined with flow cytometry and a microscope. Interestingly, PG-induced cell detachment was found to be mediated by EMP. We furthermore determined that PG at the low concentration activated Akt, a crucial cell-signaling molecule, and then controlled cell proliferation and migration. Overall, our findings suggest that PG at low doses maintains vascular stability by promoting endothelial cell proliferation, and enhances the efficacy of wound healing by cell proliferation and migration activity.

This thesis was a phenomenological study of an after-school picture book making program for middle school students. This study attempted to establish a theoretical system for picture book making activity by analyzing the process of self-discovery and healing through the picture book making activity. The participants were six middle school students, the picture book making activity program was organized into five stages, and in-depth interviews of the study participants and their interpretation of picture books were described. According to the research results, first, the making activity of picturebooks can construct one's own world through hyper-reality that is more excessive than the original. Second, it can be said that the fearful existence of a monster has developed awareness and insight to view its own problems from various angles through defamiliarization. These results might be that the making activity of picturebooks is a way of revealing one's existence to the world, and through this, the process of exploring and constructing the meaning of oneself and daily life. Discussion was made based on this about the creation of another world where the picturebook making activity is different from the original, the stimulating effect of the subconscious mind through the defamiliarization device, and the establishment of self-existence in picturebook creation.

In oral and maxillofacial surgery, bone graft is very important procedure for functional and esthetic reconstruction. So, many researcher studied about bone graft material like autogenous bone, allograft bone and artificial bone materials. The purpose of this study is to evaluate the quantity of bone generation induced by $Grafton^{(R)}$ graft, human allogenic demineralized bone matrix. Total 24 sites of artificial bony defects prepared using trephin bur(diameter 8 mm) on parietal bone of six adult New Zealand White rabbits. Experimental group had six defect sites which grafted $Grafton^{(R)}$(0.1 cc). Active control group had nine defect sites, into which fresh autogenous bone harvested from own parietal bone was grafted and passive control group had nine defect sites without bone graft. After six weeks postoperatively, the rabbits were sacrificed. The defects and surrounding tissue were harvested and decalcified in 10% EDTA, 10% foamic-acid. Specimens were stained with H&E. New bone area percentage in whole defect area was measured by IMT(VT) image analysis program. Quantity of bone by $Grafton^{(R)}$ graft was smaller than that of autograft and larger than that of empty defects. In histologic view $Grafton^{(R)}$ graft site and autograft site showed similar healing progress but it was observed that newly formed bone in active control group was more mature. In empty defect, quantity and thickness of new bone formation was smaller than in $Grafton^{(R)}$-grafted defect. $Grafton^{(R)}$ is supposed to be a useful bone graft material instead of autogenous bone if proper maintenance for graft material stability and enough healing time were obtained.

The purpose of this study is to provide a reference for the development of forest therapy programs for subfertile women. This exploratory study identifies the emotional characteristics of subfertile women and the demands for forest therapy according to the emotional characteristics and provides basic data for the development and operation of forest therapy programs. This study surveyed 200 subfertile women who visited a subfertility hospital in Seoul on 33 items of subfertile women's emotional characteristics and requirements of forest therapy programs. We conducted the frequency analysis, cross-analysis, and one-way ANOVA to determine the correlation and importance between the emotional characteristics of subfertile women and the demands for forest therapy programs using the SPSS 21.0 program. Emotional traits of subfertile women included pressure on pregnancy, anxiety/fear, depression, hopelessness, helplessness, loneliness, sadness, shame/guilt, impatience/frustration, and anger/hypersensitivity. Of these traits, pressure on pregnancy, depression, hopelessness, helplessness, loneliness, sadness, anger/hypersensitivity, and anxiety/fear were particularly high among subfertile women. The demands for forest therapy programs also differed according to the emotional characteristics of subfertile women. There was a significant difference in the operation mode of the subfertile couple's forest therapy program according to the pressure, shame, and guilt of pregnancy. There was a significant difference in the experience of participating in a program according to anxiety and fear and in the reason for not being able to participate in the forest therapy program according to depression, hopelessness, helplessness, loneliness, and sadness. There was a significant difference in couples participating the in the forest therapy program according to impatience and frustration. There was a significant difference in the experience of participating in the forest therapy program and the effect of self-help groups through the forest therapy program for subfertile women according to anger and hypersensitivity. We expect that the results of this study would be useful as the reference data for developing forest therapy programs for the improvement of the mental health of subfertile women.
