'The Orphan of Zhao family(Zhaoshi-Guer)'is one of the famous Chinese drama constantly transmitted for a long time from Yuan Dynasty to Qing Dynasty. The plot of the play in the transmitting process has not been changed much, but added new characters or episodes. The Kunqu, one of the Chinese drama styles was characterized by graceful music and refined literature, being very popular among the gentry of Ming and Qing Dynasty. The 'Zhaoshi-Guer' play in 'chuanqi' style of the 'The Sixty Plays' collection, is called 'Ba-yi-ji', which was sung in Kunqu崑曲 stage. Because 'The Sixty Plays' collection was widely read throughout the late Ming and Qing Dynasty, the 'The Sixty Plays' version became the model of Kunqu lineage example and so it was in the case of "Ba-yi-ji". In the end of the Ming, new performing type of drama that is called as Zhe-zi-xi(折子戱) was appeared. Zhe-zi-xi refers to make only some pieces, not the whole. With the new form of performance appeared many of the selected texts of plays have come out including 'Zui-bai-qiu'. Through the comparison between the pices of two Kunqu version, 'The Sixty Plays' and 'Zui-bai-qiu', I tried to observe the charisteristics of the Ba-Yi-ji performance of Qing dynasty. The latter succeded the former, but more performance oriented, such as using lively and easy word with the acting direction intensified and comic characters.

Estrogen-related receptor γ (ERRγ), a member of the orphan nuclear receptor family, is a key mediator in cellular metabolic processes and energy homeostasis. Therefore, ERRγ has become an attractive target for treating diverse metabolic disorders. We recently reported that ERRγ acts as a negative regulator of osteoclastogenesis induced by receptor activator of nuclear factor-κB ligand (RANKL). In the present study, we explored the effects of an ERRγ-specific modulator, GSK5182, on ERRγ-regulated osteoclast differentiation and survival. Interestingly, GSK5182 increased ERRγ protein levels much as does GSK4716, which is an ERRγ agonist. GSK5182 inhibited osteoclast generation from bone-marrow-derived macrophages without affecting cytotoxicity. GSK5182 also attenuated RANKL-mediated expression of cFos and nuclear factor of activated T-cells cytoplasmic 1 (NFATc1), pivotal transcription factors for osteoclastogenesis. Arrested osteoclast differentiation was associated with reduced RANK expression, but not with the M-CSF receptor, c-Fms. GSK5182 strongly blocked the phosphorylation of IκBα, c-Jun N-terminal kinase, and extracellular signal-regulated kinase in response to RANKL. GSK5182 also suppressed NF-κB promoter activity in a dose-dependent manner. In addition to osteoclastogenesis, GSK5182 accelerated osteoclast apoptosis by caspase-3 activation. Together, these results suggest that GSK5182, a synthetic ERRγ modulator, may have potential in treating disorders related to bone resorption.

This review discusses the cellular and molecular mechanisms by which the endometrial estrogen and progesterone receptors regulate local estrogen production, expression of the specific estrogen receptors, progesterone resistance, inflammatory responses and the differentiation and survival of endometriotic cells in endometrial inflammation. The epigenetic aberrations of endometrial stromal cells play an important role in the pathogenesis and progression of endometriosis. In particular, differential methylation of the estrogen receptor genes changes in the stromal cells the dominancy of estrogen receptor from ERα into ERβ, and results in the abnormal estrogen responses including inflammation, progesterone resistance and the disturbance of retinoid synthesis. These stromal cells also stimulate local estrogen production in response to PGE2 and the SF-1 mediated induction of steroidogenic enzyme expression, and the increased estradiol then feeds back into the ERβ to repeat the vicious inflammatory cycle through the activation of COX-2. In addition, high levels of ERβ expression may also change the chromatin structure of endometrial mesenchymal stem cells, and together with the repeated menstrual cycles can induce formation of the endometriotic tissue. The cascade of these serial events then leads to cell adhesion, angiogenesis and survival of the differentiation-disregulated stromal cells through the action of inflammatory factors such as ERβ-mediated estrogen, TNF-α and TGF-β1. Therefore, understanding of the dynamic hormonal changes during the menstrual cycle and the corresponding signal transduction mechanisms of the related nuclear receptors in endometrium would provide new insights for treating inflammatory diseases such as the endometriosis.

ESRRB (Estrogen related receptor $\beta$) is an orphan receptor, and have a role on maintaining the undifferentiated state and self-renewal of pluripotent stem cell as a transcription factor which regulates the expression of OCT4 and NANOG genes. Also, Feng et al. (2009) reported that Esrrb, Oct4 and Sox2 could induce pluripotent stem cell from somatic cells. The aim of the present study was to develop the direct delivery system of human ESRRB protein into human amniotic fluid-derived stem cells (AFSCs) and to analyze the effect of ESRRB on the regulation of pluripotency-related genes. Human ESRRB has three isoforms arisen by alternative splicing. We cloned short-form ESRRB and made a fusion protein of ESRRB and R7 for an efficient protein transfer to cell. R7 as cell-penetrating peptide(CPP) can help to transfer ESRRB into cells. R7-ESRRB-His6 protein was observed in the cytoplasm and nuclei within 5 hours after treatment. Also, we could observe R7-ESRRB-His6 protein only in the nuclei within 24 hours. Realtime PCR showed that ESRRB increased expression of OCT4 and NANOG as well as SOX2 gene. Therefore, we demonstrated that R7-ESRRB-His6 proteins were efficiently transferred into the nuclei of AFSCs and work well as a possible transcription factor.

In this study, we examined the efficacy of the immune regulation of ${\beta}$-1,3/1,6-glucan and Lactobacillus plantarum LM1004 on atopic dermatitis models. The oral administration of ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004 on mice significantly decreased the amount of scratching, leakage to evans blue, and concentrations of serum immunoglobulin E (IgE) and histamine compared with the atopic dermatitis - induced group. When atopic dermatitis was induced, the transcription factors (GATA-3, retinoic acid-related orphan receptor ${\gamma}$ T [$ROR{\gamma}T$]) and cytokines (interleukin-4 [IL-4], IL-17) of Th2 and Th17 cells were overexpressed at the transcriptional level, and they significantly decreased with oral administration of ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004. In addition, ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004 were shown to modulate the immune balance by increasing the expression of Th1 and Treg transcription (T-bet, forkhead box p3 [Foxp3]) and cytokines (interferon-${\gamma}$ [IFN-${\gamma}$], transforming growth factor-${\beta}$ [TGF-${\beta}$]). Galectin-9 and filaggrin were significantly lower in the atopic dermatitis - induced group and significantly higher in the ${\beta}$-1,3/1,6-glucan-treated group. In contrast, thymic stromal lymphopoietin (TSLP) was highest in the atopic dermatitis-induced group, while mice that were orally administered ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004 showed similar TSLP levels to the control group. These results indicate that ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004 have immunomodulatory effects and atopic dermatitis improvement effects in an animal model of atopic dermatitis. Therefore, it is expected that ${\beta}$-1,3/1,6-glucan and L. plantarum LM1004 can be used as natural materials in the treatment of atopic dermatitis.

The aim of this study was to examine the effectiveness of oral health promotion program in a group of 9~18-year-old children and adolescents living in four orphanages in Dong-gu, Daejeon. The program was based on oral disease prevention program including oral health education, fluoride application and scaling every six months. Oral health status of total 109 orphans was examined by one dentists who were trained in 2010 Korean National Oral Health Survey. Dental caries index, community periodontal index and modified patient hygiene performance index (M-PHP) were checked using dental unit chair. Child oral health impact profile (COHIP) and subjective oral health recognition survey were carried out. Compared with data of 2010 national sample, the mean of decayed, missing and filled teeth showed no difference between the subjects and test values, but the means of decayed teeth, decayed surface, toothbrushing frequency of the subjects showed to become worse with advancing years in spite of oral health promotion program. COHIP, subjective oral health status showed lower than test values, too. In M-PHP and Calculus index, the subjects showed better by periodic oral health education and scaling. We suggest that oral health promotion program for orphans include oral disease treatment program as well as preventive program to improve oral health of orphans efficiently. And, oral health promotion program has to be connected with psychological support for improving quality of life of orphans.

Child and youth welfare law in Korea is vague and complex. In a narrow sense it means the research on the provisions of the Child Welfare Act. In a broad sense it embraces all of the social welfare system regarding to the protection for children and youth. Regardless of the scope of child and youth welfare law it should be cleared what the term of child and youth means in Korean legal regulation. Historically, child protection in Korea was based on the good intentions of individuals to protect war orphan children from poverty or danger after the end of the Korean War. It is the story of the evolving status of children from being viewed as dependant of the parents to becoming rights-based citizens, even not in Constitution. In Korea neither parents nor children have constitutionally recognized right. According to Korean Constitution the parents have only the obligation to educate their children. And the state ist obliged to improve the welfare of the youth(section 34). In compliance with this article there are lots of statutes regulating youth welfare. This article reviews the legal definition of child and youth to test the uncertain definition of child and youth welfare in relation to the treatment of children's and youth's legal status in Korea. According to the Child Welfare Act child is the person under age of 18, while the legal definition of youth oscillates between the person under the age of 19 and the person over the age 9 to the age of 23. As a result child welfare is often used as the synonym of youth welfare, and vice versa. The lack of the arrangement of the legal definition of child and youth is based on the historical reasons that the legal definitions of youth (under the age of 19 or over the age 9 to the age of 23) newly appeared in the statutes regulating youth welfare, whereas the Child Welfare Act still maintained the definition of child under the age of 18. In order to get rid of the confusion of the definition of the child and youth, a part of certain statues should combine with another Act according to the purpose of the individual amended statutes. And the definition of child and youth should be subdivided into 3 or 4 classes, namely infant(0-6), child(7-13), youth(14-18) and young adult(19-26). Furthermore this article proposes a reform of the existing legal system pursuant to the nature of the law, i.g. whether the issued or amended Act takes on a selective(residual) or universal character.
