It is important for residents to give opinions and participate in urban regeneration projects. Urban regeneration college is being operated to strengthen the capacity of residents. In this study, the educational satisfaction of the students was surveyed while conducting the program of urban regeneration college. By analyzing survey, we intend to derive implications when constructing an urban regeneration college education program. The survey was conducted on 215 students from urban regeneration college in y-gun. Analysis was performed using the spss24.0 program. As a result of factor analysis, it was classified into three factors: education design, education culture, and education support. All three factors had significant differences in educational satisfaction. Satisfaction with education had a significant effect on the possibility of village development. Satisfaction was different according to the contents of the educational program according to the awareness of urban regeneration. For those who are aware of urban regeneration, educational culture among educational programs has more influence on educational satisfaction. Those who were not aware of urban regeneration had an effect on education support and education satisfaction. The results of this study can be used as basic data when planning educational programs for urban regeneration college.

Objectives : Although moxibustion is one of the most frequently used methods in oriental medicine, effect of moxibustion in myofiber regeneration and muscle fatigability is hardly studied. This study was researched to observe the effect of moxibustion in myofiber regeneration and muscle fatigability. Methods : We reviewed studies which contained moxibustion and published after 2000s in Pubmed. We also reviewed domestic studies in RISS, KISS and DBPIA, but only three studies were researched. Results : In myofiber regeneration, moxibuston has improved blood flow in muscle tissue and recover tissue injuries fast. Especially, moxibustion trigger an increse of HSP levels, which protect the cell against irreversible damage, apoptosis and death. Thus, that helps to stimulate myofiber regeneration. In many studies, as moxibustion stimulate PMRs and decrease fatigue substances, such as lactate acid and creatinine, so moxibustion is considered to be effective to recover and prevent muscle fatigability. Based on such effects, moxibustion is considered to have an effect on TPs, but have been hardly studied. Conclusions : Although Moxibution is considered to be effective in myofiber regeneration and muscle fatigability, futher study is needed.

Urban regeneration is a project to enhance the competitiveness. Therefore, it is necessary to examine the contents and expected effects of urban regeneration projects. In this study, we classified and analyzed the contents and expected effects of the 11 neighborhood urban regeneration pilot projects. The main results are as follows; First, physical regeneration is the most popular in terms of project contents, and social approach is the most typical for the expected effects. Second, the project of social regeneration is mainly focused on strengthening the capacity of residents. Third, the most expected effect of physical regeneration was about the improvement of landscape. Fourth, the most expected effect of social regeneration was the contents of residents' participation. Finally, there is a need for the development of projects that can expect a combination effects rather than a single effect. The urban regeneration new deal projects need to pay more attention to projects that can have various effects based on the development of competitive urban contents.

The purpose of this study was to evaluate the adjunctive combined effect of demineralized freeze-dried bone allograft(DFDB) in guided bone regeneration on supra-alveo-lar peri-implant defect. Supra-alveolar perio-implant defects, 3mm in height, each including 4 IMZ titanium plasma-sprayed implants were surgically created in two mongrel dogs. Subsequently, the defects were treated with 1 of the following 3 modalities: Control) no membrane or graft application, Group1) DFDB application, Group2) guided bone regeneration using an expanded polytetra-fluoroethylene membrane, Group3) guided bone regeneration using membrane and DFDB. After a healing period of 12-week, the animals were sacrificed, tissue blocks were harvested and prepared for histological analysis. Histologic examination were as follows; 1. New bon formation was minimal in control and Group 1, but considerable new bone formation was observed in Group 2 and Group 3. 2. There was no osteointegration at the implant-bone interface in the high-polished area of group2 and Group 3. 3. In fluorescent microscopic examination, remodeling of new bone was most active during week 4 and week 8. There was no significant difference in remodeling rate between group 2 and group 3. 4. DFDB particles were observed, invested in a connective tissue matrix. Osteoblast activity in the area was minimal. The results suggest that guided bone regeneration shows promising results in supra-alveolar peri-implant defects during the 12 week healing period although it has a limited potential in promoting alveolar bone regeneration in the high-polished area. There seems to be no significant adjunctive effect when DFDB is combined with GBR.

Hair loss is one of the most common chronic diseases, with a detrimental effect on a patient's psychosocial life. Hair loss results from damage to the hair follicle (HF) and/or hair regeneration cycle. Various damaging factors, such as hereditary, inflammation, and aging, impair hair regeneration by inhibiting the activation of hair follicle stem cells (HFSCs) and dermal papilla cells (DPCs). Formyl peptide receptor 2 (FPR2) regulates the inflammatory response and the activity of various types of stem cells, and has recently been reported to have a protective effect on hair loss. Given that stem cell activity is the driving force for hair regeneration, we hypothesized that FPR2 influences hair regeneration by mediating HFSC activity. To prove this hypothesis, we investigated the role of FPR2 in hair regeneration using Fpr2 knockout (KO) mice. Fpr2 KO mice were found to have excessive hair loss and abnormal HF structures and skin layer construction compared to wild-type (WT) mice. The levels of Sonic hedgehog (Shh) and β-catenin, which promote HF regeneration, were significantly decreased, and the expression of bone morphogenetic protein (Bmp)2/4, an inhibitor of the anagen phase, was significantly increased in Fpr2 KO mice compared to WT mice. The proliferation of HFSCs and DPCs was significantly lower in Fpr2 KO mice than in WT mice. These findings demonstrate that FPR2 impacts signaling molecules that regulate HF regeneration, and is involved in the proliferation of HFSCs and DPCs, exerting a protective effect on hair loss.

An efficient genetic transformation protocol is a fundamental requirement for high regeneration capacity from cultivated durum wheat (Triticum durum) varieties. In this study, wereportedtheeffectsoftwoauxins,2,4-dichlorophenoxyaceticacid(2,4-D)and4-amino-3,5,6-trichloropicoli nicacid(picloram), at a concentration of 2 mg/Laloneandincombination on the embryogenic callus and plantlet regeneration of four durum wheat varieties (Amria, Chaoui, Marouane, and Tomouh) using mature embryos (MEs) and immature embryos (ImEs). Significanteffectsofvariety,culturemedium(theauxinused),andvariety-mediuminteraction were observed on the callus weight and plantlet regeneration of both MR and ImE explants. The medium used for callus induction significantly affected plantlet regeneration (p < 0.001). Comparedto2,4-D, picloram led to a higher plantlet regeneration rate in both ME and ImE explants (19.8% and 40.86%, respectively). Plantlet regeneration also varied significantly depending on the variety and medium used. PicloramledtohighplantletregenerationofbothME and ImE explants in all varieties except Tomouh, which showed high plantlet regeneration of ME explants in 2,4-D. A comparison of ME and ImE responses indicated that ImEs are the best explants for high plantlet regeneration in durum wheat. Ourfindingssuggestthatpicloramisthebestauxin and should be used instead of 2,4-D due to its positive effect on increasing plant regeneration of durum wheat ME and ImE explants.

In the 20th Century, urban regeneration was changed to holistic regeneration and Ballymun of Ireland was one of the example of leading projects which using holistic regeneration over ten years. In Deajeon, there is a successful project call as "Rainbow project", using holistic regeneration. Any previous case needs to be checked thoroughly and the result needs to be studied for next project. The purpose of this study was to delineate the effect of Socio-Physical regeneration on social network. For this research, research tool was developed to combination of previous social exclusion index. This research was a survey research which used Systematic Random Sampling. In conclusion, it was not enough time to change people's behavior dramatically but even though a change is very low, it is very meaningful. Changing from people's behavior to people's mind, is a step to a goal.
