Objectives: This study assessed the economic value of 2 major initiatives within the national infectious disease response system of the Korea Disease Control and Prevention Agency (KDCA): the Training Programs for Public Health Workforce (TPPHW) and the Infectious Disease Informa...

Entry, Descent and Landing Process Technologies of Mars Landers and Research Trends in Deceleration Technology

화성은 태양계 행성 중 높은 생명체 존재 가능성을 가지고 있다. 또한, 지구 외 새로운 거주지로서 화성 탐사에 대한 시도가 지속되고 있다. 최근에는 화성 탐사를 위한 로버뿐 아니라 유인 탐사선을 보내기 위해 탐사선 크기는 커지고 있다. 이에 따라 탐사선의 성공적인 착륙을 위한 감속 시스템이...

Gas-driven needle-free dental injection enables tunable and predictable soft-tissue penetration: high-speed kinematic and micro-computed tomography validation

Needle-free jet injectors are a promising alternative to conventional dental needles, particularly for patients with injection-related fear. However, the actuation mechanism can substantially affect jet formation, delivery consistency, and tissue penetration. This study compared...

Comparison of modified thoracoabdominal nerve block via perichondrial approach with serratus intercostal plane block and rectus sheath block combination in laparoscopic cholecystectomy: a randomized controlled trial

Patients undergoing laparoscopic cholecystectomy (LC) may experience severe postoperative pain. Peripheral nerve blocks, as a component of multimodal analgesia, are now widely employed in postoperative pain management. This study investigated the effects of modified thoracoabdomi...

World’s population susceptible to water risks is concentrated in two of the 58 IPCC reference regions

The use of climate reference regions is a common practice in climate change research and impact assessment studies 1 , 2 , 3 , 4 , having been utilized especially within the context of the Intergovernmental Panel on Climate Change (IPCC)’s Assessment Reports (ARs) over the past 2...

Reconciling strong coordination and anion-reinforced solvation structure enables nonflammable electrolytes for potassium-ion batteries

Nonflammable electrolytes are pivotal for improving the safety of potassium-ion batteries. However, their broad adoption has been hindered by the inadequate electrode compatibility of conventional nonflammable electrolytes, which typically result from strong solvation and excessi...

Perforated acute appendicitis on computed tomography revealing underlying tuberculosis

Tuberculous appendicitis is an extremely rare manifestation of gastrointestinal tuberculosis and is often clinically and radiologically indistinguishable from conventional acute appendicitis. We report the case of a 27-year-old man who presented with fever and pain in the right l...
