Sparassis crispa is a medicinal mushroom, which has been reported to have anti-cancer effect. In this study, we designed to investigate the effects of Sparassis crispa extracts on the production of nitric oxide (NO) in LPS-stimulated RAW264.7 cells. The pre-treatment of the extracts prior to add LPS in RAW264.7 cells suppressed NO production and iNOS expression at protein and mRNA levels. The phosphorylation of $I{\kappa}B{\alpha}$ was inhibited by the extracts, which was induced through suppressing the activation of $NF-{\kappa}B$. Sparassis crispa extracts showed the effect on the down-regulation of STAT-1 activation in a dose-dependent manner. In LPS-stimulated RAW264.7 cells, $NF-{\kappa}B$ was translocated into the nucleus, while the treatment of Sparassis crispa extracts induced to sequestered $NF-{\kappa}B$ in the cytosol. These experimental results determined that Sparassis crispa extracts play a inhibitory role in inflammatory reactions via regulating NO production, which suggests potential as a component of inflammatory drugs.

Now in order to overcome the weakest points of the rural areas of the city of Kimje and, transform them into rural cultural villages which have local governing systems suitable to new localization age and activate this plan, we selected Daesan Village as a model village which had shown a lot of potentials in the basic research and studied it dividing it into the former part and the latter part. We studied Daesan village in the former part focusing on state analysis and basic ideas and in the latter part focusing on master plan and detail planning. We can summarize the conclusion like the followings. 1. Daesan Village located 8 kilometer away from the downtown Kimje and the city of Iksan respectably has comparatively good environment of good sunny place as an open field whose surrounding configuration of the ground consists of farming lands and low hills in front and rear. It has 38 farming households in all. 2. Human environment(인문환경); the village road whose width is about 4 meters is forming a flow system forking off into three. There is a route bus which operates three times a day even into the inside of the village. The main sources of revenue are vegetables in facilities, fruits and floriculture. Their average revenue is about 10.5 million won. 3. Here in DaeSan Village a legend dealing with Teasan literally meaning a big mountain consist of th village's tradition and you can see the tombs of a very faithful son and Anwi an army general in the age of the Japanese Invasion of Korea of 1592 to 1598 inside the village. 4. 85 out of the eitire population 141 whose age are over 20 showed very positive attitudes in a questionnaire about, making the village a cultural one and its development. 5. The basic of planned ideas is to increase the revenue of the farming household by making the village a professional farming one which has a state-of the-art production facility and agricultural technique. It is to make the village the one where people can enjoy the sense of the rural life and the farmer can enjoy their lives through consumptive and consistant leisure and resting activities. 6. We are planning to make entrance space, life space, rest and sport space, and cultural space considering the characteristics of the village and the demand of the resident. We are also planning to make tile entire city of Kimje an information transmitting base in short and long term perspectives. 7. DaeSan Village was planned as a place where tradition and the future exist together. On the basis of this concept we planned future programs for Daesan Village and in the latter part of the study master plans and detail plans will be continued.the regional agricultural condition. The development permissions were only during the period of restricted to use ($1979.12{\sim}1993.11$). We propose that the authority of development permission should be given to the local autonomy government, because the local government has the knowledge of its individual agricultural conditions.

Traditionally, the larvae of Allomyrina dichotoma (AD), a species of the rhinoceros beetle, have been widely used for their antidiabetic, antihepatofibrotic, antineoplastic, and antiobesity effects. The United Nations' Food and Agriculture Organization has reported on the possibility of using edible insects in human dietary supplements in the future. However, despite the growing interest in insect-based bio-active products, the biological activities of these products have rarely been studied. Previously, we reported that AD larvae inhibit the in vitro differentiation of adipocytes via transcription factor downregulation. In this study, our objective was to evaluate the effects of a hot-water extract of AD larvae on allergy and inflammation. To investigate the inhibitory effect of the extract on allergic reactions, we measured the levels of ${\beta}-hexosaminidase$, tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin-4 (IL-4), and cyclooxygenase-2 (COX-2) after activation of RBL-2H3 cells using Compound 48/80. In addition, the inhibitory effect of the extract on inflammation was determined using Raw 264.7 cells after lipopolysaccharide (LPS) stimulation. The extract significantly inhibited the ${\beta}-hexosaminidase$, $TNF-{\alpha}$, IL-4, and COX-2 levels in RBL-2H3 cells. Furthermore, it effectively inhibited the inflammatory cytokine IL-6, nitric oxide, and inducible nitric oxide synthase expression in LPS-stimulated Raw 264.7 cells. These results suggest that AD larval extract can be potentially developed as an antiallergic and anti-inflammatory therapeutic agent.

The purpose of this study is to explore the methods to activate and functional changes of rural centers to improve residents' quality of life and secure sustainability in rural areas. The existing policy for activating rural centers lacks for placeness because walking-focused features of a Myeon seat have been changed due to the improvement of physical environment for easy car accessibility. They also wanted to solve abandoned houses and secure parking lots in the landscape plan. Based on analysis results, design guidelines were suggested. Long-stay tourism programs for outside visitors should be developed through the rural center activation project. They should be linked with projects for preserving the history of Byeongyeong Fortress and developing Hamel Village. Mountain trails and waterfront should be created to enhance accessibility and linkage methods with other resources should be prepared. As Byeongyeong-myeon has various tourism resources, design guidelines for each element should be made for a macroscopic direction and systematic landscape management.

This study was conducted in response to the global trend of emphasizing the importance of "everyday landscapes", focusing on the perspective of those who have returned to rural life. With a focus on the case of Gokseong-gun in Jeollanam-do, 460 diaries written by these individuals were collected and analyzed using text mining techniques such as "frequency analysis", "topic modeling", and "sentiment analysis". The analysis of noun morphemes was interpreted from a cognitive aspect, while adjective morphemes were interpreted from an emotional aspect. In particular, this study applied semantic network analysis to overcome the limitations of existing sentiment analysis, and extracted a word network list and examined the content of nouns connected to adjectives that express emotions to identify the targets and contents of sentiments. This method represents a differentiated approach that is not commonly found in existing research. One of the intriguing findings is that the urban-to-rural migrants identified everyday landscapes such as "flowers on neighborhood walking paths", "harvest of a garden", "neighborhood events", and "cozy cafe spaces" as important. These elements all contain visual and enjoyable aspects of everyday landscapes. Currently, many rural villages are attempting to add visual elements to their everyday landscapes by unifying roof colors or painting murals on walls. However, such artificial measures do not necessarily leave a lasting impression on people. A critical review of current policies and systems is necessary. This research is significant because it is the first to study everyday landscapes from the perspective of urban-to-rural migration using diaries and text mining. With a lack of domestic research on everyday landscapes, this study hopes to contribute to the activation of related research in Korea.

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic debilitating disease affecting ruminants worldwide. In the present study, we aimed to determine the major gene networks and pathways underlying the immune response to MAP infection using whole-blood cells, as well as provide the potential transcriptional markers for identifying the status of MAP infection. We analyzed the transcriptional profiles of whole-blood cells of cattle identified and grouped according to the presence of MAP-specific antibodies and the MAP shed by them. The grouping was based on the results obtained by ELISA and PCR analyses as follows: i) Test1 group: MAP-negative results obtained by ELISA and positive results obtained by PCR; ii) Test2 group: MAP-positive results obtained by ELISA and negative results obtained by PCR; iii) Test3 group: MAP-positive results obtained by ELISA and positive results obtained by PCR; iv) uninfected control: MAP-negative results obtained both by ELISA and PCR analysis. The results showed down-regulated production and metabolism of reactive oxygen species in the Test1 group, activation of pathways related to the host-defense response against MAP (LXR/RXR activation and complement system) in the Test2 and Test3 groups, and anti-inflammatory response (activation of IL-10 signaling pathway) only in the Test3 group. Our data indicate a balanced response that serves the immune-limiting mechanism while the host-defense responses are progressing.

The Hippo-YAP signaling pathway is critical for cell proliferation, survival, and self-renewal in both Drosophila and mammals. Disorder of Hippo-YAP pathway leads to tumor development, progression and poor prognosis in various cancers. YAP/TAZ are the key downstream effectors of the Hippo pathway and they can be inhibited through LATS1/2, core kinases in the Hippo pathway, mediated phosphorylation. In this study, we investigated the effect of Angelica gigas Nakai extract (AGNE) on Hippo-YAP/TAZ pathway. First, ANGE induced YAP/TAZ phosphorylation and dissociation of the YAP/TAZ-TEAD transcription complex. By qRT-PCR, we found that ANGE inhibits the expression of YAP/TAZ-TEAD target gene, CTGF and CYR61. In addition, the transcriptional activity of YAP/TAZ was not suppressed significantly in LATS1/2 double-knockout (DKO) cells by ANGE compared to LATS1/2 wild-type (WT) cells, which means AGNE inhibits YAP/TAZ signaling through direct action on LATS1/2. Further, it was confirmed that AGNE-induced activation of LATS1/2 inhibited the migration potential of the vector-expressing cells by suppressing YAP/TAZ activity. The reduced migration potential was restored in active YAP-TEAD expressing cells. Taken together, the results of this study indicate that ANGE downregulates YAP/TAZ signaling in cells through the activation of LATS1/2.

Oxidative stress is a key factor in the pathogenesis of benign prostatic hyperplasia (BPH) that leads to inflammation. This study aimed to evaluate the ameliorative effects of Salvia miltiorrhiza Bunge extract (HLT-101) on BPH through the regulation of oxidative stress and inflammation. A testosterone propionate (TP)-induced BPH rat model was orally administered HLT-101 (20, 40, or 80 mg/kg), and its effects on oxidative stress- and inflammation-related gene expression were examined. Further, HLT-101 was assessed for its effect on reactive oxygen species (ROS) levels and Nrf-2/HO-1 signaling pathways in BPH-1 cells. HLT-101 decreased testosterone-induced excessive free radical production and inflammatory factor activation. Moreover, HLT-101 treatment significantly decreased the intracellular ROS level in the TNF-α and IFN-γ treated BPH-1 cells through the activation of Nrf-2. In addition, HLT-101 treatment inhibited the NF-κB pathway and androgen receptor (AR) signaling, which is highly linked to the pathogenesis of BPH. Therefore, HLT-101 has the potential to be an effective treatment reagent for BPH because of its ability to reduce inflammation and oxidative stress via Nrf-2/HO-1 signaling.

This study analyzed settlement motivation, life satisfaction factors, policy requirement targeting return farmers on mountain village. 8 target villages where return farmers live at least 10 people were selected according as cooperation of the local governments through literature by considering the area of the whole country. The return farmers in target villages were conducted a face to face survey with village headman's pre-coordination from February to September 2013. A total of 94 surveys were performed and 87 copies were used in the analysis. According to the results, the most important factor influenced the decision to be a return farmer was "my family health(3.97)". The correlation analysis was performed to examine factors related with satisfaction of "return farmer life in general". The result showed that "change of physical health" was the most important correlativity with 0.544 correlation coefficient and 0.05 significant level and "family relationship" was followed with 0.424 correlation coefficient and 0.05 significant level. According to the "important factor for the successful return-farmer life", 42.7% of respondents chose "harmonious relationships with local residents" and "stable source of income" was chosen by 29.3% of residents. A questionnaire for the analysis of policy requirements showed that "education system related Forestry(Agriculture)" was the highest demand with 4.oo points. The result can be used as a basis for establishing policies with activation of mountain villages to attract to constantly increasing population of return farmers.

To evaluate the antiallergic effect of fermented Ixeris sonchifolia (IS, family Compositae), we prepared IS kimchi, isolated lactic acid bacteria (LAB) from it, fermented IS with these LAB, and investigated their antiallergic effects. IS kimchi inhibited the passive cutaneous anaphylaxis (PCA) reaction induced by an IgE-antigen complex as well as the scratching behavior induced by compound 48/80 or histamine more potently than IS. When IS was fermented with LAB isolated from IS kimchi, its antiallergic effects was also increased. Of LAB used for fermentation, Lactobacillus brevis more potently increased the antiallergic effects. Its main constituents, chlorogenic acid and luteolin, potently inhibited the PCA reaction induced by the IgE-antigen complex as well as the pruritis induced by compound 48/80 or histamine. These constituents inhibited the expression of pro inflammatory and allergic cytokines, TNF-$\alpha$. and IL-4, and transcription factor NF-${\kappa}B$ activation induced by the IgE-antigen complex in RBL-2H3 cells, as well as the degranulation of RBL-2H3 cells induced by the IgE-antigen complex. Luteolin more potently inhibited these allergic reactions than chlorogenic acid. These findings suggest that the antiallergic effect of IS can be increased by LAB fermentation, and the fermented IS might improve allergic reactions such as pruritus, anaphylaxis, and inflammation.
