Purpose: This study was performed to find the current problems of PET/CT data from other hospitals. Materials and Methods: The subjects were acquired from 64 hospitals referred to our department for image interpretation. The formats and contents of PET/CT data were reviewed and the phone questionnaire survey about these were performed. Results: PET/CT data from 39 of 64 hospitals (61%) included all transaxial CT and PET images with DICOM (Digital Imaging Communications in Medicine) standard format which were required for authentic interpretation. PET/CT data from the others included only secondary capture images or fusion PET/CT images. Conclusion: The majority of hospitals provided limited PET/CT data which could be inadequate for accurate interpretation and clinical decision making. It is necessary to standardize the format of PET/CT data to transfer including all transaxial CT and PET images with DICOM standard format.

혈관의 안쪽 막인 내막에 콜레스테롤이 침착하고 세포 증식이 일어나면 죽종이라는 것이 만들어진다. 내부는 죽처럼 물러지고 그 주위는 단단한 섬유성 막인 경화반으로 둘러싸이게 되는데, 이를 죽상경화라고 한다. 이렇게 불안정한 경화반이 파열되어 혈관 안에 혈전이 생기고 혈관이 급격하게 좁아지거나 막히는 현상을 죽상동맥경화증이라고 한다. 죽상 동맥경화증은 질병으로 나타나기 전까지는 증상이 없으므로 예방이 중요하다.

Purpose: This study was conducted to update nursing practice guidelines for intravenous infusion published in 2017. Methods: The guideline update process was carried out using 22 steps developed by NICE and SIGN. It was agreed to update domains related to central venous infusion therapy. Contents related to peripheral infusion would be updated later. Results: Updated guidelines for central venous infusion therapy consisted of 6 domains and 195 recommendations. The number of recommendations by domain was 11 for general instruction, 14 for central vascular access devices (CVAD) and add-on devices, 13 for nursing management before insertion of CVAD, 30 for management during insertion of CVAD, 51 for management after insertion of CVAD, and 76 for complications. A grade was 29 (14.9%), B grade was 87 (44.6%), and C grade was 79 (40.5%) in the strength of recommendations. A total of 37 (19.0%) recommendations were newly developed and 23 (12.3%) previous recommendations have been modified. The newly developed recommendations were mainly related to the infection control methods. Conclusion: The updated guideline is focused on safe maintenance of central venous infusion therapy. Through this guideline, it is hoped to minimize the occurrence of complications and improve the standardization and efficiency of nursing practice.

Purpose: The purpose of this study was to identify nursing interventions frequently used with cancer patients. Nursing records from 5 general hospitals for patients with stomach, liver, lung or colon cancer were analyzed. Method: A descriptive study methodology was used and nursing records for 15 patients in each disease category at each hospital, who were admitted and discharged during June 2007 were analyzed. Results: Five domains of NIC were found and the physiological(basic) domain was most frequent (31.52%). Twenty two classes of NIC were identified with risk management for safety being most frequent (22.49%). For the 119 nursing interventions identified, the most frequent was pain management with 7,827 (12.31%), followed by prevention of falls (11.76%), surveillance (6.79%) and wound care (5.12%). Nursing activities of pain management and prevention of falls were comparable to activities listed in literature on guidelines for evidence based and best practices in nursing care. Eight of the 17 nursing activities for pain management, and 9 of 14 for fall prevention were consistent with these guidelines. Conclusion: In this study, nursing interventions were found to be focused on physical care, monitoring patients' condition and education. We have to develop diverse nursing interventions and a convenient recording process.

Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.

한국에서 유행하는 페염균 type을 결정하기 위한 기초 실험을 수행하여 서울대병원과 서울중앙병원의 환자로부터 분리한 88개의 폐염균주를 담즙산에 의한 용해도 및 Optochin에 대한 민감성 등을 측정하고 폐염균의 type을 결정하기 위해서 Double diffusion, Countercurrent immunoelectrophoresis, Rocket immunoelectrophoresis 방법 등으로 폐염균 항혈청과 반응하였다. 또한 ATCC로부터 구입한 폐염균주를 이용하여 배지조성의 변화에 따른 폐염균 생장을 측정하기 위해 CAT broth, Brain Heart Infusion broth, Defined Media에서 3가지 type의 균주(Type I, III, IV)를 접종하고 37$^{\circ}C$에서 배양하면서 1시간마다 550nm에서 흡광도를 측정하였다. 3가지 type (Type I, III, IV)의 폐염균주로부터 협막다당류를 phenol Iysis 추출법으로 폐염균 Capsule 다당류의 분리하여 Total Sugar 함량, Uronic acid 함량, 0-Acetyl 함량, 단백질 함량, 핵산 함량, 분자량분포 Countr-current immunoelectrophoresis 등을 실시하여 폐염균 백신 규격에 부합되는지 확인하였다. 수집한 88개의 폐염균주가 모두 담즙산에 의해 용해되고 6mm Optochin disc를 사용하였을때 성장 저지원이 모두 14mm 이상으로 나타나 감수성이 있어서 폐염균임을 확인하였으며 폐염균의 type 결정에 필요한 방법을 설정하였다. 배지조성에 따른 폐염균의 생장을 측정한 결과 CAT broth 에서는 Type I만이 잘 배양되었고 Type III, IV는 늦게 배양되었으나, Brain Heart Infusion broth에서는 3가지 Type이 모두 잘 배양되었고, Defined Media 에서는 Type I만이 성장되었을 뿐 나머지 두 Type은 배양되지 않았다. 본 실험방법으로 분리된 폐염균 다당류는 폐염균 백신 규격중의 6가지 항목에서 적합하였으며 Statens(Denmark)로부터 구입한 항체와 뚜렷한 침강선을 나타내었다.

Increasing demands for esthetic dental treatment, zirconia, which has high mechanical and esthetic properties, had been applied more and more in clinics. Therefore, assessment of biocompatibility of zirconia is necessary. In this article, a review of in vivo studies of zirconia compatibility was performed. In vivo studies showed zirconia had great biocompatibility both on soft and hard tissue. Studies with various animals and patients reported high biocompatibility of zirconia. In terms of bone synthesis and bone adhesion, zirconia showed similar biocompatible properties to titanium. On the other hand, zirconia could be used as implant. For using as an implant, various methods of Hydroxyapatite (HA) coating had been suggested. Since HA coating on titanium implant showed some problems such as low bonding strength and degeneration of HA, HA-zirconia composite, HA-coated zirconia, and HA-zirconia functionally graded material (FGM) or intermediate layer of alumina had been proposed. These methods showed higher bonding strength and biocompatibility.

Cardiac arrest is a critical medical emergency where immediate response is essential for patient survival. This is especially true for Out-of-Hospital Cardiac Arrest (OHCA), for which the actions of emergency medical services in the early stages significantly impact outcomes. However, in Korea, a challenge arises due to a shortage of dispatcher who handle a large volume of emergency calls. In such situations, the implementation of a machine learning-based OHCA detection program can assist responders and improve patient survival rates. In this study, we address this challenge by developing a machine learning-based OHCA detection program. This program analyzes transcripts of conversations between responders and callers to identify instances of cardiac arrest. The proposed model includes an automatic transcription module for these conversations, a text-based cardiac arrest detection model, and the necessary server and client components for program deployment. Importantly, The experimental results demonstrate the model's effectiveness, achieving a performance score of 79.49% based on the F1 metric and reducing the time needed for cardiac arrest detection by 15 seconds compared to dispatcher. Despite working with a limited dataset, this research highlights the potential of a cardiac arrest detection program as a valuable tool for responders, ultimately enhancing cardiac arrest survival rates.
