Background: This study provides an update to a landmark 2004 report describing demographics, training, and trends in adherence to thoracic surgery practice standards in Canada. Methods: An updated questionnaire was administered to all members of the Canadian Association of Thoracic Surgeons via email (n=142, compared to n=68 in 2004). Our report incorporates internal data from Ontario Health and the Canadian Partnership Against Cancer. Results: Forty-eight surgeons completed the survey (male, 70.8%; mean±standard deviation age, 50.3±9.3 years). This represents a 33.8% response rate, compared to 64.7% in 2004. Most surgeons (69%) served a patient population of over 1 million per center; 32%-34% reported an on-call ratio of 1:4-1:5 days, and the average weekly hours worked was 56.4±11.9. Greater access to dedicated geographic units per center (73% in 2021 vs. 53% in 2004) has improved thoracic-associated services and house staff, notably endoscopy units (100% vs. 91%), with 73% of respondents having access to both endobronchial and endoscopic ultrasound. Access to thoracic radiology has also improved, particularly regarding positron emission tomography scanners per center (76.9% vs. 13%). Annual case volumes for lung (255 vs. 128), esophageal (41 vs. 19), and mediastinal resections (30 vs. 13), along with hiatal hernia repair (45 vs. 20), have increased substantially despite reports of operating room availability and radiology as rate-limiting steps. Conclusion: This survey characterizes compliance with current practice standards, addressing the needs of thoracic surgeons across Canada. Over 85% of respondents were aware of the 2004 compliance paper, and 35% had applied for resources and equipment in response.

본 연구는 비영어권의 내원객 수가 나날이 증가하고 있고 그에 따른 방사선 검사 시 언어의 소통 및 의사전달에 한계가 있었다. 이에 검사를 위해 제작한 안내서를 배부 후 설명 전후에 따른 개선 효과를 알아 보았다. 검사 부위 인지 여부는 점수 척도가 통계적 유의성이 없었고 검사의 불편 정도, 호흡 지침 이해 정도, 검사 설명 만족도는 제작한 안내서 설명 전후에 따라 점수 척도가 향상되었으며 통계적 유의성이 있었다. 비영어권 외국인 내원객의 경우 영어나 한국어로 했을 때 보다 자국의 문자로 설명하는 것에 만족하였고, 그 방법 또한 검사실 내 조명 신호를 이용하여 외국인 내원객에게 호흡을 조절해야 하는 시기를 알려 줌으로써 효과적인 검사를 시행할 수 있었다. 향후 다양한 언어 통역 프로그램과 다양한 검사 부위에 따른 안내서 제작과 도구 개발, 방사선사 및 의료진의 외국어 능력 향상 등 여러 관점에서 의사소통 수단이 구현 될 때 비로소 의료서비스 및 영상 의학적 검사의 질이 개선 될 수 있을 것이다. 앞으로 다른 영상의학 검사실에서도 영어나 한국어를 이해하지 못하는 비영어권 외국인을 검사할 때 사용할 수 있는 매뉴얼을 마련하는데 기초 자료로 활용 될 수 있을 것으로 사료 된다.

South Korea is not a wasteland of publicly funded health care-instead, it has a good medical social security system known as the national health insurance (NHI). The NHI of Korea has three unique features; (1) low premiums, low insurance fees, and low coverage; (2) obligatory designation of medical institutions; (3) and allowance of non-benefit services. These features have made hospitals and doctors interested in profit-seeking. However, the commercialization of medical institutions has taken place in both private- and public-established sectors. A basic problem of commercialization is the co-existence of the obligatory designation of medical institutions and non-benefit services. The problem became worse in the Kim Dae-Jung government because it officially permitted non-benefit services. Since 2000, the Korean government has consistently pursued benefit extension policies, but the coverage rates of the NHI have stagnated. In addition, premiums and current medical expenses have markedly increased because policy-makers have emphasized accessibility to the NHI, while ignoring important principles of medical social security such as a needs-based approach and patient-referral system. In order to resolve the commercialization problem, the obligatory designation of medical institutions to the NHI should be changed to a contract system, and non-benefit services should be prohibited at NHI institutions. We must re-establish the patient-referral system via a needs-based approach. We also need to build a primary healthcare system and public health policies. We should make a long-term plan for healthcare reform.

Most patients and parents and guardians display frequent anxiety due to radiation exposure during outpatient, ward, and pediatric general radiographic examinations. This is a behavior that perceives only the harmfulness of radiation. For the recognition of medical radiation, we conduct surveys on outpatients, inpatients, and pediatric parents and guardians to identify their awareness, and then use the radiation dose promotional materials After providing accurate information on the use of radiation, the outpatient, inpatient, and pediatric parents and guardians were asked to explain the change in awareness. The questionnaire items were classified into five categories: repetitive radiation awareness for diagnosis, awareness of exposure dose, availability of exposure information, awareness of radiation risk, and awareness of health problems caused by radiation. There was a statistically significant difference in the items of recognition result of medical radiation, although there was a slight difference in the individual items in the pre and post-recognition results of providing information about the radiologists of the protector and the outpatient(p<0.05). Therefore, through the installation of these promotional materials, we will improve our awareness of medical radiation safety during general radiography surveillance in the Department of Radiology to provide better quality medical information and medical services, thereby contributing to strengthening the competitiveness of the hospital.

This study attempts to analyze the factors affecting the intention of transferring to another hospitals among radiology technologists. 344 cases were reviewed in 5 university hospitals and 1 general hospital. Self-administered questionaire were given to study the socioeconomic characteristics, working conditions, job satisfaction level, and the reasons for transfer among the technologists. The major findings were as follows : 1. Job position and hospital characteristics had a statistically significant relationship with the intention of transferring to another hospital. 2. Those who were not satisfied with their salaries and promotional opportunity showed a higher tendency towards to transfer. 3. Those who were less satisfied with the opportunity for developing the personal ability and had the negative attitude on their job showed a higher tendency to transfer. 4. Those who did not sustain good relationship with their superiors and co-workers scored high on the tendency to transfer. 5. In the result of mutiple regression, recognition of radiation hazard, job satisfaction, satisfaction with salary levels, job attitude were significantly related to transfer. The above indicate that besides economic incentives, job satisfaction and organizational culture to promote their ability and form a good relationship with organization members were very important to decrease the intention of transfer. Since these results represent only 6 hospitals from a limited area, more hospitals nationwide, especially small and medium-sized institutions where there is a high turnover rate of employment, need to be examined in order to investigate the various factors that affect the intention of transferring.

의료민영화는 의료서비스의 질, 의료비의 억제 그리고 소득재분배 및 위험분산 등에 매우 중대한 영향을 미치게 될 것이다. 본 연구는 의료민영화에 대한 본질을 이해하지 못한 채 너무 많은 주장들이 난무한 상황을 개선하고자 실시되었다. 본 연구에서는 현재 논란이 되는 의료민영화에 대한 의미를 파악하고, 그에 따른 주장들을 다루고 있다. 의료민영화 정책에 대한 찬성 및 반대의 주장을 동시에 살펴봄으로서 객관적인 관점수립에 도움을 주고자 한다. 보건의료가 자본주의적 시장접근을 통하여 다각화 되고 산업의 일환으로 전환되어 신성장 동력으로 바라보아지는 과정이다. 그러나 보건의료서비스는 사람의 생명을 다루는 실천적 행위이기 때문에 보편적인 방법으로의 접근 및 성장에 제약이 따른다. 더불어 정부의 이익 또는 의료기관의 이익만을 위한 서비스에 해당하지 않는다. 올바른 의료민영화 정책의 수립을 통하여 공공서비스로 자리 잡은 우리나라 의료시스템의 변화방향을 제시하고 국민의 의료비 부담을 증가하지 않는 정책적 논의의 필요성을 제시한다.

Objective : Subarachnoid hemorrhage (SAH) is a condition characterized by bleeding in the subarachnoid space, often resulting from the rupture of a cerebral aneurysm. Delayed cerebral ischemia caused by vasospasm is a significant cause of mortality and morbidity in SAH patients, and inflammatory markers such as systemic inflammatory response index (SIRI), systemic inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), and derived NLR (dNLR) have shown potential in predicting clinical vasospasm and outcomes in SAH patients. This article aims to investigate the relationship between inflammatory markers and cerebral vasospasm after aneurysmatic SAH (aSAH) and evaluate the predictive value of various indices, including SIRI, SII, NLR, and dNLR, in predicting clinical vasospasm. Methods : A retrospective analysis was performed on a cohort of 96 patients who met the inclusion criteria out of a total of 139 patients admitted Trakya University Hospital with a confirmed diagnosis of aSAH between January 2013 and December 2021. Diagnostic procedures, neurological examinations, and laboratory tests were performed to assess the patients' condition. The Student's t-test compared age variables, while the chi-square test compared categorical variables between the non-vasospasm (NVS) and vasospasm (VS) groups. Receiver operating characteristic (ROC) curve analyses were used to evaluate the diagnostic accuracy of laboratory parameters, calculating the area under the ROC curve, cut-off values, sensitivity, and specificity. A significance level of p<0.05 was considered statistically significant. Results : The study included 96 patients divided into two groups : NVS and VS. Various laboratory parameters, such as NLR, SII, and dNLR, were measured daily for 15 days, and statistically significant differences were found in NLR on 7 days, with specific cut-off values identified for each day. SII showed a significant difference on day 9, while dNLR had significant differences on days 2, 4, and 9. Graphs depicting the values of these markers for each day are provided. Conclusion : Neuroinflammatory biomarkers, when used alongside radiology and scoring scales, can aid in predicting prognosis, determining severity and treatment decisions for aSAH, and further studies with larger patient groups are needed to gain more insights.

Purpose: Preoperative identification of the intraosseous posterior superior alveolar artery (PSAA) is critical when planning sinus surgery. This study was conducted to determine the distance between the cementoenamel junction and the PSAA, as well as to identify factors influencing the detection of the PSAA on cone-beam computed tomography (CBCT). Materials and Methods: In total, 254 CBCT scans of maxillary sinuses, acquired with 2 different scanners, were examined to identify the PSAA. The distance from the cementoenamel junction (CEJ) to the PSAA was recorded at each maxillary posterior tooth position. Binomial logistic regression and multiple linear regression were employed to evaluate the effects of scanner type, CBCT parameters, sex, and age on PSAA detection and CEJ-PSAA distance, respectively. P-values less than 0.05 were considered to indicate statistical significance. Results: The mean CEJ-PSAA distances at the second molar, first molar, second premolar, and first premolar positions were 17.0±4.0 mm, 21.8±4.1 mm, 19.5±4.7 mm, and 19.9±4.9 mm for scanner 1, respectively, and 17.3±3.5 mm, 16.9±4.3 mm, 18.5±4.1 mm, and 18.4±4.3 mm for scanner 2. No independent variable significantly influenced PSAA detection. However, tooth position (b=-0.67, P<0.05) and scanner type (b=-1.3, P<0.05) were significant predictors of CEJ-PSAA distance. Conclusion: CBCT-based estimates of CEJ-PSAA distance were comparable to those obtained in previous studies involving cadavers, CT, and CBCT. The type of CBCT scanner may slightly influence this measurement. No independent variable significantly impacted PSAA detection.

DR은 방사선과 뿐만 아니라 병원전체의 생산성 및 업무의 효율성에서 중요한 요소로 자리잡아가고 있다. DR환경은 CR보다 다양한 Parameter를 가지고 있어 양질의 의료서비스 제공이 가능하다. 현재 각 병원의 방사선과는 Film-Screen system에서 Full-PACS를 통한 DR 환경으로 변화하고 있다. Full-PACS를 사용하고 있는 본원에서는 DR환경에서의 일반촬영 System중 CR과 DDR의 최적노출조건과 그에 따른 Image quality가 어떻게 표현되는 지 알아보고자 본 연구에 임하게 되었다. 본 실험을 통하여 CR과 DDR의 Image quality는 같은 노출조건 하에서는 DDR이 더욱 우수하다는 것을 알 수 있었다. 그리고 DDR system에서도 AEC를 사용했을 때의 Image에 대한 점수가 사용하지 않았을 때보다 조금 더 높은 것을 알 수 있다. 특히 Skull, Chest부분에서는 DDR의 AEC기능이 Image quality를 향상시키는데 유용함을 간접적으로 알 수 있었다. (AEC기능이란 피사체를 통과한 X선을 Detector내에 있는 Ion chamber를 이용하여 전리전류를 검출하는 기구로서 적정농도 도달 시 X선의 조사를 제어하도록 되어있다.) 이 기능은 다양한 피사체의 두께에 따른 노출조건을 고려하지 않아도 적정농도를 나타낼 수 있기 때문에 보다 손쉬운 촬영이 이루어질 수 있다. 이 실험결과로 좋은 Image quality를 얻기 위해서는 적절한 노출조건의 선정이 중요함을 알 수 있었다. 앞으로도 무한한 발전 가능성이 있는 DDR system에 대한 연구가 좀 더 필요하겠다.
