T cell receptor (TCR) signaling plays a critical role in T cell development, survival and differentiation. In the thymus, quantitative and/or qualitative differences in TCR signaling determine the fate of developing thymocytes and lead to positive and negative selection. Recently, it has been suggested that self-reactive T cells, escape from negative selection, should be suppressed in the periphery by regulatory T cells (Tregs) expressing Foxp3 transcription factor. Foxp3 is a master factor that is critical for not only development and survival but also suppressive activity of Treg. However, signals that determine Treg fate are not completely understood. The availability of mutant mice which harbor mutations in TCR signaling mediators will certainly allow to delineate signaling events that control intrathymic (natural) Treg (nTreg) development. Thus, we summarize the recent progress on the role of TCR signaling cascade components in nTreg development from the studies with murine model.

This study analyzed the relationship between ESG performance and corporate value using panel data from Chinese equipment manufacturing companies spanning from 2012 to 2021, and it also examined whether ownership structure moderates this relationship. We have contributed to filling the gap in existing research. The main conclusions of this study are as follows: Firstly, similar to previous researches, ESG performance was found to have a positive and statistically significant impact on corporate value. Secondly, when the three dimensions of ESG - Environmental (E), Social (S), and Governance (G) - were analyzed separately, it was observed that E and S have a positive and statistically significant impact on corporate value, while G has a negative and statistically significant impact. Thirdly, ownership concentration emerged as a significant moderating factor in explaining the connection between ESG performance and corporate value. Lastly, when the three dimensions of ESG were analyzed separately, ownership concentration was found to serve as a positive moderating factor in the relationship between corporate value and E and S, but it did not play a statistically significant role for G.

Objectives: This study aimed to identify measures that can improve the quality of dental hygienists' work by analyzing the effects of role stress, resilience, and professional identity on burnout. Methods: Self-report questionnaires were administered to 339 dental hygienists working in dental institutions located in Seoul, Incheon, and Gyeong-gi, South Korea from August 1 to September 30, 2017. Results: Out of a maximum of 5 points, role stress scored an average of 2.80, resilience scored 3.61, professional identity scored 3.27, and burnout scored 2.78. The factor that most affected the exhaustion of dental hygienists was professional identity (${\beta}=-0.397$), followed by role stress (${\beta}=0.251$), and resilience (${\beta}=-0.150$). Conclusions: The results showed that the role stress, resilience, and professional identity of dental hygienists affected burnout. Efforts to reinforce the resilience and professional identity of dental hygienists may be needed alongside efforts to reduce role stress. Hence, resilience reinforcement programs alongside supplemental education programs that reinforce the work skills required of dental hygienists according to their clinical experience after graduation should be developed.

The purpose of this study was to compare the grandmothers' role performance toward their grandchildren in the elementary school between working and nonworking mother families. The subjects were 274 grandparent-grandchild pairs. The structured questionnaires, from both grandmothers and grandchildren were collected in 2001. Using statistical techniques such as factor analysis, t-test, Pearson's correlation, and multiple regression analysis, the major findings were as fellows: 1) The level of the grandmothers' role performance is moderate in general. However, the grandmothers in working mother families perform surrogate mother roles more strongly than the grandmothers in nonworking mother families.2) While contact between grandmother and grandchild is associated with the grandmother's role performance in working mother families, the grandmother's age and the closeness between grandmother and mother are related to the level of the grandmother's role performance in nonworking mother families. In conclusion, the grandmothers' role performance in working mother families was found to be more important in the supporting system than in nonworking mother families.

Background: Although Tat plays a role as a potent transactivator in the viral gene expression from the Human Immunodeficiency Virus type 1 long terminal repeat (HIV-1 LTR), it does not function efficiently in rodent cells implying the absence of a human specific factor essential for Tat-medicated transactivation in rodent cells. In previous experiments, we demonstrated that one of chimeric forms of TAR (transacting responsive element) of HIV-1 LTR compensated the restriction in rodent cells. Methods: To characterize the nature of the compensation, we tested the effects of several upstream binding factors of HIV-1 LTR by simple substitution, and also examined the role of the configuration of the upstream binding factor(s) indirectly by constructing spacing mutants that contained insertions between Sp1 and TATA box on Tat-mediated transactivation. Results: Human Sp1 had no effect whereas its associated factors displayed differential effects in human and rodent cells. In addition, none of the spacing mutants tested overcame the restriction in rodent cells. Rather, when the secondary structure of the chimeric HIV-1 TAR construct was destroyed, the compensation in rodent cells was disappeared. Interestingly, the proper interaction between Sp1 and TATA box binding proteins, which is essential for Tat-dependent transcription, was dispensable in rodent cells. Conclusion: This result suggests that the human-specific Tat cofactor acts to allow Tat to interact effectively in a ribonucleoprotein complex that includes Tat, cellular factors, and TAR RNA, rather than be associated with the HIV-1 LTR upstream DNA binding factors.
