One of the most common side effects of chemotherapeutic agents is chemotherapy-induced peripheral neuropathy (CIPN). The occurrence of CIPN is increasing as the survival rate of patients with cancer improves and the cumulative dose or duration of neurotoxic drugs increases. Approximately 30–40% of patients receiving neurologically toxic drugs experience CIPN, which eventually increases the burden of medical expenses. However, preventive measures against CIPN have not yet been established. Clinical trials have tested various drugs for the management of neuropathic pain, but only duloxetine has shown any significant effect. Further studies should evaluate nonpharmaceutical treatments, such as exercise.

Common bile duct stones (CBDS) are the most common cause of acute cholangitis. Removal by endoscopic retrograde cholangiopancreatography became the standard of care after endoscopic sphincterotomy was introduced. On the other hand, it is still difficult to remove 10-15% of CBDS completely in the first attempt for various reasons. This review describes the methods for the complete endoscopic clearance of CBDS, including difficult cases, reflecting the latest knowledge and techniques.

만성 췌장염에 동반된 췌장결석은 심한 통증을 유발하여 환자들의 삶의 질을 매우 저하시킨다. 특히 주췌관을 막고 있으며 통증을 유발하는 췌장결석은 적극적인 치료를 고려해야 한다. 먼저 췌장결석이 머리나 몸통에 위치하고, 크기가 5 mm미만인 경우에는 바로 내시경 제거를 시도해볼 수 있다. 5 mm 이상의 경우에는 먼저 ESWL을 시행하고 그 결과에 따라 추가로 내시경 제거를 고려할 수 있다. 이러한 치료에 실패하였을 경우에는 췌관경을 이용한 쇄석술이나 수술을 고려해야 하고, 가교치료로 췌관스텐트 삽입을 이용할 수 있다. Pancreatic calculi associated with chronic pancreatitis lead to severe abdominal pain, which significantly reduces the quality of life of patients. Pancreatic calculi, especially those that obstruct the main pancreatic duct and cause abdominal pain, are considered to be treated. First, if pancreatic calculi are located in the head or body and the size is less than 5 mm, endoscopic removal can be attempted. If the size is greater than 5 mm, extracorporeal shockwave lithotripsy may be performed first, and subsequent endoscopic removal may be considered depending on the results. If such treatment fails, pancreatoscopic lithotripsy or surgery should be considered. Pancreatic duct stenting may be used as a bridge therapy during this process.

Recently Korea Army developed the TICN which is the next army tactical communication system. The TICN will support ability from under environment, strategy maneuver communication system of integrated army dimension overcome and NCW. If the IER(Information Exchange Requirement) phases 3 of the future application system, the analysis that a transmission ability of the TICN is the uncapable is govern. The TICN tactical backbone's ability is very important. Therefore, network efficiency index in application and analysis of the standard protocol for the data transmission guarantee are obliged. For the TICN tactical backbone, this paper analyzes of routing protocol efficiency index and compares to superiority of the OSPF(v2) and integrated IS-IS protocols in the tactical environment. Conclusively we proposed that integrated IS-IS protocol is more suitable for TICN backbone routing protocol.

A 50-year-old female with epigastric pain was diagnosed as pancreatic neuroendocrine tumor with multiple liver metastases by radiologic imaging studies and liver biopsy. After 4 times of transarterial chemoembolizations (TACE), pylorus-preserving pancreaticoduodenectomy (PPPD) was performed and Grade 2 pancreatic neuroendocrine tumor was confirmed. Although new liver metastases were detected after the surgery, no further treatment has been given due to very slow growth of the metastatic lesions. The patient has survived for over 7 years with no symptoms related to cancer. This case suggests that a patient with pancreatic neuroendocrine tumor with multiple liver metastases could become a long-term survivor by aggressive locoregional treatments including surgery. Therefore, active multidisciplinary approaches should be considered for advanced pancreatic neuroendocrine tumors.
