Flare phenomenon refers to increased radiotracer uptake in bones despite clinical findings showing a positive response to treatment. Flare phenomena are most often observed in patients with breast or prostate cancer. Here, we present a case of bone flare in a 54-year-old male who had advanced gastric cancer with bone metastases. After three cycles of chemotherapy, a bone scan showed increased intensity, but the patient`s bone pain was alleviated and abdominal computed tomography revealed a decrease in the size of the primary mass and metastatic lymph nodes. We therefore continued chemotherapy using the same regimen, and a follow- up bone scan revealed decreased intensity. A flare phenomenon after treatment is rare in cases of gastric cancer with bone metastasis. Although flare phenomena are not common, they should be considered in patients with gastric cancer when the clinical results are inconsistent with bone-scan findings. (Korean J Med 2016;91:321-324)

폐정맥혈전증은 매우 드문 질환으로, 폐 이식 수술이나 폐엽 절제술 후 합병증 그리고 악성 종양 등에 의해 발생한다. 일반적으로 종양의 침범이나 수술 후 정맥 문합 부위의 봉합선 등에 의한 국소적 협착에 의해 발생하는 것으로 알려져 있다. 저자들은 대엽성 폐렴에 의한 국소적 혈전 정맥염의 기전에 의해 발생한 폐정맥혈전증 증례 1예를 경험하였기에 보고하는 바이다. Pulmonary vein thrombosis is a rare disease related to a lung malignancy or complication after lung surgery. Generally, it is caused by tumor invasion or localized stenosis of a vein anastomosis site after an operation. Here we report a case of pulmonary vein thrombosis that occurred in a patient with local thrombophlebitis due to lobar pneumonia. (Korean J Med 2016;91:283-286)

In this study, compressive strength test based on the deep corrugated strugated plate and standard corrugated strugated plate was carried out to assess the compressive characteristics of two types corrugated strugated plate with various bolt connections. An ultimate strength and yeild stress are also examined in the study. Connections bearing failure and local buckling failure occurred when deep corrugated strugated plate was under the compressive force. Furthumore, two kinds of failure mode related with standard corrugated strugated plate and deep corrugated strugated plate and bolt shear failure also occurred.
