  • Thomas L. Friedman's "Our New Historic Divide: B.C. and A.C. ― The World Before Corona and the World After" column is becoming the talk of the times. Whoever talks about the post-Corona world mentions "BC/AC" as a new concept. However, people seem to be overusing the term "BC/AC" while overlooking the specific context that Friedman emphasized. So, taking into account the cultural differences and contexts of the East and the West highlighted in Friedman's column, we devised the "BC/AC" ten-paradigm hypothesis. We hope these ten cultural shifts will be the first step in examining the post-Corona world.

  • Objective: In this case report, we aimed to determine the effect of Kyejigadahuang-tang on central post-stroke pain (CPSP). Methods: A 42-year-old woman presented with whole-body neuralgia due to CPSP. According to the diagnostic system based on Shanghanlun provisions (DPIDS), the patient was treated with Kyejigadahuang-tang. The results were evaluated using the Numeric Rating Scale (NRS) and Korean Neuropathic Pain Questionnaire (KNPQ). Results: After administration of Kyejigadahuang-tang for 30 days, the NRS score decreased from 8.5 to 3 and the KNPQ score decreased from 151 to 51. Conclusions: The patient completely recovered from CPSP following treatment with Kyejigadahuang-tang according to DPIDS.

  • It is announced a new procedure for the real-time overall hull response monitoring system depends on inclinometer sensor data. The procedure requires a few inclinometer sensors' data, located on the deck. Sensor data is used to obtain curvature values; and curvature values are used to find out displacements or relevant moment values according to pre-calculated moment-curvature diagrams. Numerical studies are demonstrated with reasonable accuracy for the pre-ultimate and the post-ultimate nonlinear behaviors. Elastic, inelastic, and post-collapse structural bending moment capacity determination of the hull has been presented. The proposed inverse engineering technique will be able to see the response of the hull in real-time with high accuracy to manage the course and speed when cruising or control the loading and the unloading process at the port.

  • Breast augmentation is becoming more common, be it for cosmetic reasons or post-mastectomy. Multiple articles in the literature describe the imaging findings of various types of cosmetic breast augmentation. Some articles describe imaging findings for different types of post-mastectomy reconstructions. This essay aims to serve as a comprehensive reference for the multimodality imaging of various types of breast augmentations in native breast and post-mastectomy reconstructions. Familiarity with these findings will facilitate the detection of complications and new or recurrent breast malignancies in patients. With the extensive illustrations provided in this essay on normal and abnormal imaging findings of augmented breasts, readers will receive exposure that will facilitate effective practice.

  • The purpose of this present paper is to obtain inclusion relations between various subclasses of harmonic univalent functions by using the convolution operator associated with generalized distribution series. To be more precise, we obtain such inclusions with harmonic starlike and harmonic convex mappings in the plane.

  • The U.S. Congress has been known to effectively control the bureaucracy. On one hand, Congress adjusts the degree of discretion provided to the bureaucracy when making agencies or legislation: ex ante control. On the other hand, it also performs the oversight activities to punish or correct undesirable behaviors of bureaucrats: ex post control. While the dynamics of each control mechanism is widely examined theoretically, few have attempted to empirically investigate this with a special attention to partisan politics in Congress. I attempt to fill this gap by measuring the two types of control mechanisms, testing theoretical assertions, and analyzing the dynamics under the two control mechanisms.

  • Runt-related transcription factor 2 (RUNX2) is a key transcription factor for bone formation and osteoblast differentiation. Various signaling pathways and mechanisms that regulate the expression and transcriptional activity of RUNX2 have been thoroughly investigated since the involvement of RUNX2 was first reported in bone formation. As the regulation of Runx2 expression by extracellular signals has recently been reviewed, this review focuses on the regulation of post-translational RUNX2 activity. Transcriptional activity of RUNX2 is regulated at the post-translational level by various enzymes including kinases, acetyl transferases, deacetylases, ubiquitin E3 ligases, and prolyl isomerases. We describe a sequential and linear causality between post-translational modifications of RUNX2 by these enzymes. RUNX2 is one of the most important osteogenic transcription factors; however, it is not a suitable drug target. Here, we suggest enzymes that directly regulate the stability and/or transcriptional activity of RUNX2 at a post-translational level as effective drug targets for treating bone diseases.
