Objectives The purpose of this study is to understand the research trend of reports on forest therapy so far and analyze the Korean medicine therapy being applied in forest therapy programs. Methods We ran a keyword search on domestic databases with the following keyword 'forest therapy, forest healing, forest treatment, recreational forest, forest bath, forest experience'. The search took place in December 2014 and there was no limit to search time. A total of 334 forest therapy articles have been selected. Results The number of research on forest therapy continued to rise from 1985, with 334 articles being published from 84 journals. When those 188 articles were sorted by their contents and methods, except 146 articles of survey on simple satisfaction, recognition and visting, 94 were clinical studies, 79 were literature studies, 15 were experimental studies. Of the 94 clinical researches, there were 52 CCTs (Controled Clinical Trials), 39 ODs (efficacy studies with either a controlled or an Other than controlled Design) and 3 RCTs (Randomized Clinical Trials). Among the clinical researches, there were a total of 21 studies that used Korean Medicine programs, and meditation was the most popular, being used in 18 studies. Herbal food and tea therapy and Qigong were used in 3 studies each, and Korean medicine music programs were used in 2 studies. Conclusions A systematic and standardized Korean medicine forest therapy program must be developed, and based on the program, more research treating diseases should be conducted.

Depression is one of the most common mental disorders. Some characteristics of depression in Korea were elucidated. The tendency to express depressive feeling through somatic complaints is more prominent in Korea than in Western countries. Careful studies on depressive symptoms suggest that guilt and suicidal idea are apparent among Korean depressive patients as well as among Western subjects. But most depressive patients in Korea are reluctant to express suicidal idea, which is hidden under the somatic complaints. We should remember the possibility of research artifacts or cultural bias with regard to the evaluation of depressive symptoms of a country in comparison with other countries. Non-pharmacological treatment of depression includes dynamic psychotherapy, cognitive behavioral therapy, interpersonal psychotherapy, self-care treatment, etc. Some kinds of Korean culture relevant psychotherapies are introduced: Tea therapy, Imago therapy, Tao psychotherapy, and combined approach. Interest in the aged people is growing recently, and the research about the factors which affect the depressive disorders in older patients and treatment strategy for them is ongoing.

Objectives : This study aims to prepare the basic data of the teeth color by measuring tooth mode using the color of the maxillary central incisor of the college students in their twenties as the dental colorimeter, and oral health and eating habit characteristics were examined. Methods : The maxillary central incisor(1 teeth) of the subjects of study as 467 students(male 89, female 378) was measured during the period from November 14, December 2 2011, so the color of total 467 teeth were examined, and oral health and eating habit characteristics were researched. Results : 1. As the results of measurement of the shade, value, hue of maxillary central incisor by the general characteristics of the subject, the major(shipbuilding information, special rehabilitation for young children) was higher at 3.3 of the shade, and the grade(1), age($$\geq_-20$$), major(beauty culture & cosmetic, occupational therapy) showed higher at +2 of the value, and the grade(1) and all major showed higher at R3 of the hue. 2. As the results of measurement of the shade, value, hue of maxillary central incisor by the oral health characteristics, the subjective teeth color(yellow) and the education of oral health(no) showed higher at 2.5 of the shade. 3. As the results of measurement of the shade, value, hue of maxillary central incisor by the eating habit characteristics of the subjects, the chocolate showed higher at 3.0 and 2.0 of the shade, and the red pepper paste showed higher at +2 and STD of the value, and the green tea showed higher at $R_3$ of the hue. Conclusions : This study demonstrates that the color of the maxillary central incisor showed differences various tendency according to the oral health and eating habit characteristics.

Diabetes mellitus is a systemic disease with profound effects on oral health and periodontal wound healing. Uncontrolled diabetes adversely affects surgical wound healing and is often associated with abnormal proliferation of fibroblasts. Human gingival fibroblasts and PDL cells were chosen because they are intimately involved in periodontal therapy and are important for the success of surgical procedure such as guided tissue regeneration. The aim of the present study was to elucidate whether cellular activity and collagen synthesis by glucose pre-treated human gingival fibroblasts and PDL cells are influenced by insulin, and whether healthy cells differ from glucose treated cells. Cells were cultured with DMEM at $37^{\circ}C$, 5% $CO_2$, 100% humidified incubator. To evaluate the effect of glucose on gingival fibroblasts and periodontal ligament cells, the cells were seeded at a cell density of $1{\times}10^4\;cells/well$ culture plates and treated with 20 and 50mM of glucose for 5 days. Then MTT assay was carried out. To evaluate the effect of insulin on glucose-pretreated cells, the cells were seeded at a cell density of $1{\times}10^4\;cells/well$ culture plates and treated with 20 and 50mM of glucose for 5 days. After incubation, $10^3$, $10^4$ and $10^5mU/l$ of insulin were also added to the each well and incubated for 2 days, respectively. Then, MTT assay and collagen synthesis assay were carried out. The results indicate that cellular activity of gingival fibroblasts significantly increased by glucose while periodontal ligament cells were unaffected and cellular activity of gingival fibroblasts and periodontal ligament cells were unaffected by insulin. Collagen synthesis of gingival fibroblast with 20mM glucose and insulin unaffected, but 50mM glucose and insulin increased than control. Collagen synthesis of periodontal ligament cell with 20mM glucose and $10^5mU/l$ insulin significantly increased than other groups and 50mM glucose pretreated PDL cells significantly increased at $10^3mU/l$ insulin but decreased at $10^4mU/l$ insulin. Our findings indicated that these cell types differed in their growth response to glucose, and the increase in collagen synthesis was significantly raised at insulin level of $10^3mU/l$ in gingival fibroblasts and periodontal ligament cells except 20mM glucose pretreated periodontal ligament cells.
