An 1 year old intact male mixed dog (weighing 20 kg) was presented with primary complaints of abdominal distension and severe exercise intolerance. Electrocardiogram found profound bradycardia (46-79 beats/min) with atrial standstill. Laboratory studies found no particular abnormalities. Serum cortisol and T4 concentration were within normal range. Diagnostic imaging studies revealed generalized cardiomegaly, ascites, dilation in all cardiac chambers, absence of atrial contraction, absence of transmitral A-peak, mitral and tricuspid valve insufficiency and normal left ventricular systolic dimension. Based on diagnostic findings, the case was diagnosed as idiopathic atrial standstill. The dog was treated with conventional therapy for heart failure.

The Iksan Ssangneung (twin tombs), a pair of tombs comprising the Daewangneung (large royal tomb) and the Sowangneung (small royal tomb), were constructed in the typical style of stone tunnel and chamber tombs in the Baekje Kingdom during the Sabi period (538 to 660 AD) of ancient Korea. Soil layers exposed during excavation of Sowangneung in a trench east of the tomb are: the bottommost layer, the ground level layer, the Panchuk (rammed earth) layer of the Baekje, the layer created by a grave robbery, and soil recovered during the Japanese colonial period. Soil samples were obtained by segmenting an easy stratigraphic horizon into sub categorized soil layers, and their material properties were analyzed; they are composed mainly of sandy loam based on the particle size distributions. In the site foundation, loamy sand is packed in the bottommost layer, and sandy loam with high sand and silty sand fills most of the overlying layer. The central and topmost portion of the Baekje layer is composed of loam with high clay content. All soil layers show geochemical behaviors similar to those of the bottommost layer. X-ray diffraction analysis verified kaolinite in all layers, also observed in soil layers displaying high crystallinity. Kaolinite and halloysite were identified by scanning electron microscopy. Thus, we conclude that the Baekje layer of the Sowangneung is composed of sandy loam containing kaolin procured from near the site. An impermeable middle to upper layer was created using viscous loam. The top of the tomb was closed tightly.
