We assess Hirschman's theory of exit, voice, and loyalty in the context of voluntary exit from organizations in the public workforce. Specifically, we test the effects of loyalty and voice on the likelihood a person states their intention to leave. We assess these relationships using data from the Federal Human Capital Survey. Our statistical analysis provides evidence that perceptions about voice and loyalty limit exit at all levels of the organizational hierarchy. Yet, dissatisfaction with pay

We assess the usefulness of a theory of organizations, the Resource-Based View, for the study of public agencies. We examine the differential impacts of an array of organizational resources (administrative, human, financial, physical, political, and reputation resources) on a core measure of federal agency effectiveness. Our analysis shows that certain types of resources have positive impacts on agency effectiveness, such as administrative (number of members in top governing structure), personne

A multi-center clinical trial was completed successfully with planned Pulsta valve implantation and demonstrated good mid-term effectiveness without device-related serious adverse events.

Chimeric antigen receptor (CAR)-based adoptive T-cell therapy is a highly promising treatment for lymphoid malignancies, and CD20 is an ideal target antigen. We previously developed a lentiviral construct encoding a third generation CD20-targeted CAR but identified several features that required additional optimization before clinical translation. We describe here several improvements, including replacement of the immunogenic murine antigen-binding moiety with a fully human domain, streamlining

Upper gastrointestinal symptoms are more common in subjects with a higher consumption of spicy foods, younger age and female gender, regardless of TRPV1 genotypes and the H. pylori infection status. Capsaicin-rich foods may induce stomach fullness.

Our data indicate that CD4⁺ cell help during cell culture maintains robust CD8⁺ CAR T cell function, with implications for clinical cell manufacturing.

The univentricular heart after the Fontan operation may have a blind pouch formed by the pulmonary stump or rudimentary ventricle according to the anatomy before surgery. Thrombosis in an intracardiac blind pouch of patients with a univentricular heart is a hazardous complication. Because only a few reports have described this complication, the authors evaluated the clinical significance of thrombosis in an intracardiac blind pouch of a univentricular heart. They performed a retrospective review

The Gerbode shunt, known as the left ventricle to the right atrial communication, is a rather rare finding, following surgical closure of septal defects. Even though the surgical closure is accepted as a treatment of choice, we report a successful percutaneous transcatheter closure of the Gerbode shunt in a 3-months old baby who weighed 3 kilograms.

After the start of the pandemic, the Kawasaki disease incidence decreased, and the percentage of patients with Kawasaki disease aged <1 year increased. These findings provide support for the hypothesis suggesting an infectious trigger in Kawasaki disease.

In South Korea, Gram-positive cocci represent 85% of all etiologic agents of IE in children with an increasing trend in the proportion of staphylococci.

In Asian population with a high incidence of heterotaxy syndrome, the heterotaxy syndrome was identified as the poor prognostic factors for Fontan surgery. The preoperative low mPAP and less AVVR are associated with better early and long-term outcomes of Fontan surgery.

The number of hospital cares for ACHD dramatically increased more than five times from 2005 to 2017. We need preparations for efficient healthcare for adults with CHD such as a multi-dimensional approach, effective communication, and professional training.

An X‐band gallium‐nitride high electron mobility transistor (GaN HEMT) transformer‐based Doherty power amplifier (TBD PA) module with a phase lineariser has been developed. The TBD PA uses Cree's 6 W GaN HEMT bare die and realised in seven‐layer PCB. The proposed lineariser is employed before the TBD PA to compensate the phase distortion during the Doherty operation. The implemented TBD PA with 9.56 GHz continuous wave test shows a 38.5% power‐added efficiency at 39.6 dBm output power. Linearity
