최근 터널 구조물이 점차 노후화됨에 따라 터널의 안전성을 평가하기 위한 점검 및 진단이 많이 수행되고 있다. 그러나 터널구조물의 상태 및 안전성 평가에 대한 명확한 기준이 없어 조사자의 주관적인 판단에 의존할 수 밖에 없는 실정으로 이에 대한 체계적인 기준정립이 요구되고 있다. 또한 기존방법은 터널라이닝에 대한 평가에 많은 비중을 주고 있어 지반구조물로서의 터널특성을 제대로 반영하지 못하고 있으며, 상태평가요소과 터널등급산정과정이 체계적이지 못하여 이에 대한 보완이 필요하다 할 수 있다. 따라서 본 연구에서는 터널 상태 및 안전성 평가방법의 문제점을 개선하기 위한 새로운 터널구조물상태평가기준을 제시하였다. 본 기준은 국내외의 터널기준을 분석하여 상태평가요소를 선정하고 이를 점수화하였으며, 대표등급산정방법을 정량화하므로서 터널상태를 객관적으로 평가할 수 있도록 하였다. 본 기준과 방법은 터널구조물에 대한 상태평가에 객관성과 신뢰성을 확보하여 보다 효율적인 안전점검 및 진단업무에 활용될 수 있다.

Purpose: The purpose of this study was to compare the efficacy of two imaging modes in a cone beam computed tomography (CBCT) system in detecting root fracture in endodontically-treated teeth with fiber posts or screw posts by selecting two fields of view. Materials and Methods: In this study, 78 endodontically-treated single canal premolars were included. A post space was created in all of them. Then the teeth were randomly set in one of 6 artificial dental arches. In 39 of the 78 teeth set in the 6 dental arches, a root fracture was intentionally created. Next, a fiber post and a screw post were cemented into 26 teeth having equal the root fractures. High resolution (HiRes) and standard zoom images were provided by a CBCT device. Upon considering the reconstructed images, two observers in agreement with each other confirmed the presence or absence of root fracture. A McNemar test was used for comparing the results of the two modes. Results: The frequency of making a correct diagnosis using the HiRes zoom imaging mode was 71.8% and in standard zoom was 59%. The overall sensitivity and specificity in diagnosing root fracture in the HiRes mode were 71.79% and 46.15% and in the standard zoom modes were 58.97% and 33.33%, respectively. Conclusion: There were no significant differences between the diagnostic values of the two imaging modes used in the diagnosis of root fracture or in the presence of root canal restorations. In both modes, the most true-positive results were reported in the post space group.

Laryngopharyngeal reflux disease (LPRD) is the result of retrograde flow of gastric contents to the laryngopharynx. Laryngoscopic findings and special questionnaires are first step of diagnosis of LPRD. Empiric trials of Proton pump inhibitor' test (PPI test) is recommended as treatment and diagnosis. However confirmation of reflux is then recommended primarily in patients with persistent symptoms despite acid-suppressive therapy. The 24 hour ambulatory double pH monitoring has been a gold standard method in diagnosis of LPRD even though it has some limitation. The combined multichannel intraluminal impedance and pH monitoring is a new-rising test tool. It can detect acid/non-acid, liquid/gaseous reflux and clearance of refluxate. The water siphon test is also used for diagnosis of LPRD.

Acute pancreatitis is a common gastrointestinal disease that is associated with significant morbidity and consumes enormous health care resources. As such, it requires up-to-date evidence-based diagnosis and standard treatment guidelines with broad support from the clinician. Korean Pancreatobiliary Association has developed clinical practice guidelines for the diagnosis and treatment of acute pancreatitis to provide a framework for clinicians to manage acute pancreatitis and to improve national health care. The guidelines were divided into four parts: the diagnosis of acute pancreatitis, the assessment of the severity, the initial management, and the treatment of necrotizing pancreatitis and local complications of acute pancreatitis. In this article, we summarize and present the diagnosis and treatment guidelines for acute pancreatitis established in Korea.

Objective : The region, observation period, figuration of pulse, pulse frequency, process of diagnosis and related diagnostic methods in traditional pediatric pulse diagnosis were studied in this article. Method : The articles related to traditional pediatric pulse diagnosis in Traditional medical classics, and analysis to the characteristics of it was done, then lastly, the principle of pulse manifestation and the meaning of application to modern times were considered. Result & Conclusion : It is difficult to catch the figuration of pediatric pulse because of dynamic change of body conditions, fast heartbeat and narrow region of pulse. Therefore, the pulse diagnosis appropriated for children have been developed and combined with the special diagnosis methods, for example, palpation of forehead and observation of index finger. The traditional pediatric pulse diagnosis is done with just one finger palpation in the period of 3 to 5 years old to identify the speed, length, size and height of pulse. The standard average of pulse frequency is 7~8 par breath in the period of 3 to 5 years old according to traditional medical classic.

Although most clinicians now agree that sinusitis can afflict children of all ages, appropriate diagnosis remain controversial. Sinusitis is one of the most challenging diagnoses for a clinician, because there is a lack of validated diagnostic criteria for acute rhinosinusitis. Symptoms generally include nasal congestion, purulent nasal discharge, and cough .The physical examination is often unsuccessful in confirming the diagnosis. If purulent discharge is seen oozing from the middle meatus, the diagnosis of acute rhinosinusitis is almost certain. Purulent drainage may also be seen in the posterior pharynx and accompanied by halitosis. Absence of light by transillumination may indicate acute rhinosinusitis. Imaging studies are not necessary to confirm the diagnosis of sinusitis in children younger than 6 years and should be used sparingly in children older than 6 years. Sinus radiographs still have several advantages over CT scanning including the relatively low cost and the ability to obtain films without the use of sedation in younger children. Positive findings of sinusitis on plain film include air-fluid levels, complete opacification, or mucosal thickening greater then 4 mm. The CT scan however, is significantly more sensitive then plain films in detecting these abnormalities. Although recovery of bacteria from a sinus aspiration is considered reference standard for diagnosis in pediatric rhinosinusitis, its routine used by pediatricians is not practical and therefore is not recommended.
