Maintenance of stemness and optimization of differentiation potentials during in vitro expansion of human adipose-derived stem cells
Adipose-derived stem cells (ADSCs) show similar characteristics to bone marrow-derived stem cells, the gold standard of MSCs, in terms of their characteristics and differentiation potentials. However, ADSCs show sub-optimal functionality compared with the gold standard. In our effort to secure enough number of allogeneic stem cells from healthy donor, FGF2 was pretreated during hADSCs in vitro expansion culture. FGF2 significantly increased the dimension of cell expansion as shown in Figure 1 and 2. Pre-treatment of FGF2 not only induced an increase of cell number â approx. 44-fold at passage 7 - but also potentiated the differentiation potentials of hADSCs. Differentiation potentials of hADSCs expanded in the presence of FGF2 was evaluated in vitro and in vivo. hADSCs pre-treated with FGF2 showed enhanced in vitro osteogenesis and chondrogenesis. Using in vivo ectopic bone model, in vivo osteogenic potential of hADSCs pretreated with FGF2 was also evaluated and abundant osteoid/bone matrix was formed in dose-dependent manner according to the concentration of pre-treated FGF2. Bone matrix formation by control hADSCs was virtually non-existent. FGF2-pre-treated hADSCs also showed enhanced in vitro chondrogenesis. hADSCs expanded with FGF2 showed increased expression of genes associated with early osteogenesis and chondrogenesis. These results shows that FGF2 can exert beneficial effect on in vitro expansion of hADSCs not only in the dimension of the expansion but also in functionality of the expanded cells.

Effects of Three Interventions with International College Students Referred for Adjustment and Language Difficulties: A Preliminary Study
This quasi-experimental study examined the effects of three interventions with international college students referred for adjustment and language difficulties. Fifty-four international students were assigned to treatment groups including expressive group counseling (n = 14), group speech therapy (n = 14), interdisciplinary counseling/speech intervention (n = 13), and the no treatment control (n = 13). Three null hypotheses were analyzed using a two factor repeated measures analysis of variance to determine whether the four treatment groups behaved differently across time according to pre- and posttest results of the ASR Total and Internalizing Problems scales and the CCSR total scores. Two null hypotheses were rejected at the alpha .05 level of statistical significance with large treatment effects. Post hoc analyses were conducted when a statistically significant interaction effect was found. The no treatment control group was established as a baseline to examine how each intervention group performed over time when compared to the no treatment control group. Results of the post hoc analysis for Total Problems indicated that international students in all three treatment groups demonstrated statistically significant improvements in total behavior problems at the alpha .025 level (Expressive counseling: p = .002, Speech: p = .01, and Interdisciplinary: p = .003) and large treatment effects (partial η2 = .33, .24, and .31, respectively), thus indicating all three may be considered effective mental health treatments to target international students' total behavior problems. Results of the post hoc analysis for Internalizing Problems indicated that the interdisciplinary counseling/speech intervention was statistically significant (p = .02) in lowering internalizing problems and had a large treatment effect (partial η2 = .22). The expressive group counseling intervention also demonstrated a large treatment effect (partial η2 = .15) although not a statistically significant level (p = .04). The large treatment effects obtained for both interventions highlight the benefit of expressive group counseling as a sole intervention, as well as when combined with group speech therapy, for ameliorating international students' internalizing problems
Analysis of Womenâs Leadership Program in Sport and Policy Proposals
PURPOSE This study analyzed the KSPO womenâs sports leadership program and foreign cases to suggest policy proposals. METHODS A literature review was conducted involving official webpage of the programs, related technical reports, media resources, and academic articles collected from international and domestic research databases. RESULTS The major results are as follows: (1) The curriculum of current program should be examined and reconstructed to achieve the intended purpose. (2) Since selfawareness is a key factor in demonstrating effective leadership, implementing selfawareness training program should be considered. (3) Mentoring is regarded to be an effective tool in promoting women leadership; therefore, establishing sustainable women mentoring program is required. CONCLUSIONS Despite several limitations, this paper is the first study, to the best of our knowledge, to review and analyze the KSPO womenâs sports leadership program comparing foreign cases for the purpose of seeking improvement. As womenâs leadership in the field of sport would become even more important in the future, this program should be redesigned to be able to train and nurture leaders so that they can progress to the higher level of decision making in sport organizations
A Qualitative Study on the Perceptual Changes of [Goal Kicking Women] Male Viewers Regarding Womenâs Football
PURPOSE This study aims to identify how the [Goal Kicking Women] TV program has changed the perceptions of male viewers on womenâs football. METHODS Using a qualitative research design, semi-structured interviews were conducted with 8 male viewers who are in their 50s. Thematic analysis was used to draw implications from the interviews. RESULTS Results show that having watched [Goal Kicking Women], 1) participants have become more familiarized with women playing football; 2) participantsâ initial stereotype about womenâs alleged inferiority in football has changed, as the performance of female stars in the program, who did not have any experience playing football, improved; and 3) the genuine passion that female stars showed for football made participants think that womenâs football was just as good as menâs. CONCLUSIONS This study provides practical and academic implications, as it identifies menâs perceptions on womenâs football and analyzes the influence of [Goal Kicking Women]. To conclude, establishing a foundation for planning and implementing effective policies to promote womenâs football in South Korea is recommended
Energetic Electron and Proton Interactions with Pc5 Ultra Low Frequency (ULF) Waves during the Great Geomagnetic Storm of 15â16 July 2000
The dynamics of the outer zone radiation belt has received a lot of attention mainly due to the correlation between the
occurrence of enhancing relativistic electron flux and spacecraft operation anomalies or even failures (e.g., Baker et al. 1994).
Relativistic electron events are often observed during great storms associated with ultra low frequency (ULF) waves. For
example, a large buildup of relativistic electrons was observed during the great storm of March 24, 1991 (e.g., Li et al. 1993;
Hudson et al. 1995; Mann et al. 2013). However, the dominant processes which accelerate magnetospheric radiation belt
electrons to MeV energies are not well understood. In this paper, we present observations of Pc5 ULF waves in the recovery
phase of the Bastille day storm of July 16, 2000 and electron and proton flux simultaneously oscillating with the same
frequencies as the waves. The mechanism for the observed electron and proton flux modulations is examined using groundbased
and satellite observations. During this storm time, multiple packets of discrete frequency Pc5 ULF waves appeared
associated with energetic particle flux oscillations. We model the drift paths of electrons and protons to determine if the
particles drift through the ULF wave to understand why some particle fluxes are modulated by the ULF waves and others
are not. We also analyze the flux oscillations of electrons and protons as a function of energy to determine if the particle
modulations are caused by a ULF wave drift resonance or advection of a particle density gradient. We suggest that the
energetic electron and proton modulations by Pc5 ULF waves provide further evidence in support of the important role that
ULF waves play in outer radiation belt dyanamics during storm times
Continuous non-destructive conductivity monitoring of chondrogenesis using bioimpedance tensor probe
A continuous non-destructive monitoring method is required to apply proper feedback controls during chondrogenesis. We measured the apparent conductivity and the amount of anisotropy on the top and bottom surfaces of samples in the chondrogenesis process to evaluate the ECM structure and composition changes. We compared them with histological trait to analyse the results
eIF2A, an initiator tRNA carrier refractory to eIF2 kinases, functions synergistically with eIF5B
The initiator tRNA (Met-tRNA(i)(Met)) at the P site of the small ribosomal subunit plays an important role in the recognition of an mRNA start codon. In bacteria, the initiator tRNA carrier, IF2, facilitates the positioning of Met-tRNAiMet on the small ribosomal subunit. Eukarya contain the Met-tRNAiMet carrier, eIF2 (unrelated to IF2), whose carrier activity is inhibited under stress conditions by the phosphorylation of its -subunit by stress-activated eIF2 kinases. The stress-resistant initiator tRNA carrier, eIF2A, was recently uncovered and shown to load Met-tRNAiMet on the 40S ribosomal subunit associated with a stress-resistant mRNA under stress conditions. Here, we report that eIF2A interacts and functionally cooperates with eIF5B (a homolog of IF2), and we describe the functional domains of eIF2A that are required for its binding of Met-tRNAiMet, eIF5B, and a stress-resistant mRNA. The results indicate that the eukaryotic eIF5B-eIF2A complex functionally mimics the bacterial IF2 containing ribosome-, GTP-, and initiator tRNA-binding domains in a single polypeptide.112Ysciescopu
Beyond 5G URLLC Evolution: New Service Modes and Practical Considerations
Ultra-reliable low latency communications (URLLC) arose to serve industrial
IoT (IIoT) use cases within the 5G. Currently, it has inherent limitations to
support future services. Based on state-of-the-art research and practical
deployment experience, in this article, we introduce and advocate for three
variants: broadband, scalable and extreme URLLC. We discuss use cases and key
performance indicators and identify technology enablers for the new service
modes. We bring practical considerations from the IIoT testbed and provide an
outlook toward some new research directions.Comment: Submitted to IEEE Wireless Commun. Ma
