This study is on the policy direction settings that can accomplish regional revitalization by continuously developing the various theme of rural tourism and can contribute to the improvement of the quality of life. The recent issues of SDGs are discussed, and their link with rural development, especially with rural tourism, are examined. To be specific, it focuses on healing-type rural tourism that is rising as a new theme in the tourism industry. The results have revealed the possibility of linking the indicators of SDGs and the needed resources for healing rural tourism. Therefore, it is possible to strengthen the rural tourism theme linkage, and to contribute to the regional revitalization through establishment of the detailed action indicators of rural tourism in line with SDGs. However, since research on SDGs is at an early stage, there is a need for further discussion on various examples from the rural tourism field.

This study was conducted to investigate anti-inflammatory and wrinkle improvement effects of Sophora flavescens Aiton water extracts (SWE) treated with proteolytic enzyme. The antioxidant activity of proteolyzed Sophora flavescens Aiton water extracts (SWE-E) showed increased total polyphenol content, total flavonoid content, electron-donating ability and ABTS+ free radical scavenging activity compared with SWE. To investigate the anti-inflammatory effects, the inhibition of NO production was assessed in RAW 264.7 cells induced by LPS. The SWE-E showed an increased anti-inflammatory effect compared with SWE at the same concentration. The anti-wrinkle effect was evaluated by the rate of collagenase and elastase inhibitory activity, which was determined by the MMP-1 mRNA measured in human dermal fibroblast (HDF) by quantitative polymerase chain reaction (qPCR). Collagenase and elastase are important enzymes that play roles in wrinkle formation, and SWE-E showed a significantly higher collagenase inhibition rate than non-treated extracts. The MMP-1 mRNA in HDF cells decreased in a dose-dependent manner. Moreover, SWE was shown to be a non-irritant in the BCOP assay, which is an alternative method to in vivo eye irritation test. Taken together, these results suggest that proteolytic enzyme could enhance the antioxidant activity, as well as the anti-inflammatory and anti-wrinkle effects of SWE, and that SWE-E could be used as a cosmeceutical ingredient.

Oral squamous cell carcinoma (OSCC) is the most common type of oral malignancy. Numerous therapies have been proposed for its cure. Research is continually being conducted to develop new forms of treatment as current therapies are associated with numerous side-effects. Luteolin, a common dietary flavonoid, has been demonstrated to possess strong anti-cancer activity against various human cancer cell lines. Nevertheless, research into luteolin-based anticancer activity against oral cancer remains scarce. Thus, the objective of this study was to assess the effect of luteolin as an anti-cancer agent. After treatment with luteolin, Ca9-22 and CAL-27 oral cancer cells showed condensed nuclei and enhanced apoptotic rate with evidence of mitochondria-mediated apoptosis. Epithelial-mesenchymal transition (EMT) is closely related to tumor migration and invasion. Luteolin suppressed cancer cell invasion and migration in the current study. Elevated expression of E-cadherin, an adherens junction protein, was evident in both cell lines after luteolin treatment. Luteolin also significantly inhibited transcription factors (i.e., N-cadherin, Slug, Snail, Twist, and ZEB-1) that regulated expression of tumor suppressors such as E-cadherin based on Western blot analysis and quantitative PCR. Thus, luteolin could induce mitochondrial apoptosis and inhibit cancer cell invasion and migration by suppressing EMT-induced transcription factors.

Codium fragile (Suringar) Hariot is an edible green seaweed that belong to the Codiaceae family and has been used in Oriental medicine for the treatment of enterobiasis, dropsy, and dysuria. Methanol extract of codium fragile has anti-oxidant, anti-inflammatory and anti-cancer properties, although the anti-cancer effect on oral cancer has not yet been reported. In this study, we investigated the anti-cancer activity and the mechanism of cell death by methanol extracts of Codium fragile (MeCF) on human FaDu hypopharyngeal squamous carcinoma cells. Our data showed that MeCF inhibits cell viability in a dose-dependent manner, and markedly induced apoptosis, as determined by the MTT assay, Live/Dead assay, and DAPI stain. In addition, MeCF induced the proteolytic cleavage of procaspase -3, -7, -9 and poly(ADP-ribose) polymerase(PARP), and upregulated or downregulated the expression of mitochondrial-apoptosis factor, Bax(pro-apoptotic factor), and Bcl-2(anti-apoptotic factor), . Futhermore, MeCF induced a cell cycle arrest at the G1/S phase through suppressing the expression of the cell cycle cascade proteins, p21, CDK4, CyclinD1, and phospho-Rb. Taken together, these results indicated that MeCF inhibits cell growth, and this inhibition is mediated by caspase- and mitochondrial-dependent apoptotic pathways through cell cycle arrest at the G1/S phase in human FaDu hypopharyngeal squamous carcinoma cells. Therefore, methanol extracts of Codium fragile can be provided as a novel chemotherapeutic drug due to its growth inhibition effects and induction of apoptosis in human oral cancer cells.

As the urban population continues to increase, cities grow through the expansion of high-rise and high-density residential areas, which demand good living environments to improve citizens’ quality of life. This study is based on the apartment type proposed by Moon Soo-young(2011) in accordance with the layout pattern of green spaces in three apartment complexes located in Dalseo-gu, Daegu Metropolitan City. The purpose of this research is to discover the causes of the high nutritional rate and successful planting method, as well as to suggest a plan to improve the planting structure(general complex, built apartment). According to the study results, the green area ratio of the study was the highest with 44.7% of the total area, followed by Wolbahil state(center type) with 30.3%, and the Bible Jeongnam Town(type of arrangement around buildings) with 27.3%. Shared facility centers were placed outside the apartment buildings in common with the type of arrangement around the buildings and the type of centering arrangement, and the coverage rate in the apartment complexes increased. There are many underground parking lots in the vicinity of the buildings; the center type of the buildings and the parking lots for the disabled are located underground. In general, residents use the underground parking lot, and the ground greenery ratio is higher than other types. Through the analysis of the facilities in the complex according to the type, we found the cause of high green ratio and good planting method and suggested an improvement plan for the general and constructed apartments. In the general apartment complex improvement plan, it is possible to increase the green area by minimizing the single-story buildings such as the shared facilities center and arranging these facilities in the apartments. The number of entrances is reduced due to the connectivity between underground parking lots. Reducing the area of the road within the complex can reduce the number of green spaces. It is important that water pipes are laid mainly under broad-leaved trees and that the plant structure is multi-layered. In order to estimate the construction of the apartment, we propose a method to construct the green space in three dimensions by using methods such as wall greening and rooftop greening. It is possible to utilize enough spaces to waste through the plant materials. In the plant structure, a cluster planting was arranged and the shrubs and plants were placed in the complex.

We investigated the effects of two Brucella proteins expressed in a pMAL expression system, RocF and EF-Ts, as subunit vaccines on immune modulation and protective efficacy using a mouse model. Mice vaccinated with MBP-RocF and MBP-EF-Ts displayed increased production of TNF, IFN-, MCP-1, IL-10 and IL-6, and TNF and MCP-1, respectively. Furthermore, mice vaccinated with MBP-EF-Ts showed decreased induction of IFN- and Th2-related cytokines, IL-10 and IL-6. Higher proportions of CD4+ and CD8+ T cells were observed in the blood of mice vaccinated with MBP-RocF than in the PBS-vaccinated group, although the increases were not significant. Furthermore, significantly reduced Brucella proliferation in the spleens of the MBP-RocF and MBP-EF-Ts groups were observed, but inflammation of these organs was not attenuated. Overall, these results indicate that RocF and EF-Ts could be potential subunit vaccine candidates against animal brucellosis.

Mycoplasma spp. are extracellular bacteria that colonize on the respiratory epithelium of humans and animals. It is a causative agent of pneumonia commonly complicated by opportunistic infectious bacteria. Mycoplasma spp. infection cause relatively mild disease in the absence of environmental stressors, but when complicated by secondary bacterial invaders the resultant disease can cause obvious clinical disease and severe production losses in intensively reared pigs Mycoplasma spp. are highly fastidious bacteria, difficult to culture and slow growing. Many species of Mycoplasma spp. are important pathogens causing respiratory infection in animals and known to induce huge economic losses. The aims of the present study were to develop a rapid isolation and culture method of wild type Mycoplasma spp. in pigs. We used Mycoplasma spp. genus specific direct PCR without DNA extraction procedure using PhireⓇ Animal Tissue Direct PCR Kit from the lung tissues with pneumonia lesions. Therefore, we could save the time for tissue processing and increase the accuracy of Mycoplasma spp. inclusion prediction in lung tissues. Thereafter, we used the optimized media to isolate and culture Mycoplasma spp. As the results, Mycoplasma spp. could be isolated and cultured quickly and efficiently. These results could provide an efficient strategy and method for the rapid and accurate isolation and culture of wild type Mycoplasma spp. in pigs.

Hoping this literature review supports women patients and helps in the wellness of women, we sincerely look forward to disseminate this instructive and proper information to exploit flavonoids for enhancing health promotion.

The main materials composing the outdoor space are the landscape plant materials. Even though grass plants out of landscape plant materials are efficient for water consumption and management, still, the types of grass used for landscape are extremely few. Thus, this study explores the preference on grass plants in apartment complexes to provide basic information for grass planting plan and design in the future. For this study, 171 questionnaires of two sites in Daegu and one site in Seoul were used for final analysis and the results are as follows. First, in the results of the awareness of grass plants, “do not know” (80.7%) was considerably higher than “do know” (19.3%). Second, in the results of the most preferred place for planting grass plants in apartment complexes, “trail” (31.2%) was the highest, followed by “space around the apartment building” (17.5%) and “waterscape” (15.4%). Third, for the preference on the shape of grass plants, “Upright-arching” (38.0%) was the highest, followed by “Upright-divergent” (29.2%), “Tufted” (19.9%), and “Mounded” (12.9%). Fourth, for the preferred height of grass plants, “Short size” (50.3%) was the highest, followed by “Medium size” (36.8%), and “Tall size” (12.9%). Fifth, for the preferred color of grass plants, “white” (27.7%) was the highest, followed by “green” (25.7%), “red” (20.5%), “yellow” (17.2%), and “blue” (9.0%). This information could be used as reference in case when planning and designing of grass plants in apartment complexes and further research including different regions is needed.
