목 적 : 한국에서 발생빈도가 높은 암의 하나인 직장암의 치료에 있어 전국의 각 병원 치료방사선과(방사선종양학과)에서 시행하고 있는 치료 형태를 세부 항목별로 파악하여 방사선종양학 전문의 간의 치료원칙의 차이점을 분석하고 이를 바탕으로 향후 Patterns of Care Study를 위한 연구의 기본 자료로 제시하고자 한다. 대상 및 방법 : 경인지역 소재 18개 대학병원 및 방사선종양학과가 있는 병원들의 방사선종양학과 전문의들이 모여 직장암의 방사선치료 원칙 분석을 위한 consensus committee를 구성하고, 회합 및 설문조사를 통하여 각 의사들의 방사선치료 원칙을 파악하기 위한 세부 항목 설정과 이를 토대로 직장암 환자 개개인의 치료 내용을 측정하는 구체적인 항목들을 개발하였다. 이 항목들을 이용하여 직장암의 방사선치료를 담당하고 있는 전국의 방사선종양학과 전문의들을 대상으로 설문조사를 시행한 후 각 전문의들의 의견이 일치하는 부분과 상이한 부분들을 분석하였다. 결 과 : 전문의 별 치료원칙의 측정에 사용된 항목들은 1) 치료대상환자의 선정기준 8개 항목, 2) 수술 전후 병기 및 예후 인자 검사 20개 항목, 3) 수술 및 항암화학요법과의 병용기준 7개 항목, 4) 환자의 setup 및 처치 9개 항목, 5) 모의치료시 조사야 결정 19개 항목, 6) 치료계획 5개 항목, 7) 치료 중 상태 확인 위한 이학적/병리학적 검사 4개 항목, 8) 치료 후 추적 관찰시 검사할 10개 항목 등 총 82개의 항목이 개발되었다. 이 항목들은 전국 각 병원들의 방사선종양학과 전문의를 대상으로 설문조사 되어 치료원칙에 대한 분석이 항목별로 이루어졌다. 설문조사 결과 전국의 각 병원 방사선종양학과에서 시행되고 있는 직장암의 방사선치료 형태는 일정 범위를 유지하고 있으나, 일부 항목에 있어서는 치료자 간 의견차이가 큰 것으로 나타났으며 이들 중 전체 응답자의 50% 이상에서 합의가 되지 못한 항목들은, 1) 치료환자의 선정 기준 중 수술 전 방사선치료 대상, 2) 병기 결정 검사 중 직장내 초음파(EUS, endorectal ultrasound), 흉부 CT, 뼈 스캔 등의 시행 여부, 3) 항암제와의 병용 원칙, 4) 모의치료시 소장 위치 확인을 위한 조영제 사용, 5) 조사야의 경계선 결정, 6) 치료 후 추적 관찰 시 CEA와 대장내시경의 시행여부 등이었다. 결 론 : 이견이 많은 항목들에 대해선는 향후 담당 전문의들을 대상으로 consensus meeting등을 통한 체계적인 분석 및 합의의 도출이 필요한 것으로 보이며, 본 연구에서 밝혀진 각 병원들의 치료 내용을 토대로 향후 표준화된 치료 모델 개발을 위한 Patterns of Care Study가 진행될 예정이다. Purpose : To conduct a nationwide survery on the principles in radiotherapy for rectal cancer, and develop the framework of a database of Korean Patterns of Care. Study. Materials and Methods : A consensus committee was established to develop a tool for measuring the patterns in radiotherapy protocols for rectal cancer. The panel was composed of radiation oncologists from 18 hospitals in Seoul Metropolitan area. The committee developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer. The survey items developed for measuring the treatment principles were composed of 1) 8 eligibility criteria, 2) 20 items for staging work-ups and prognostic factor, 3) 7 items for principles of combined surgery and chemotherapy, 4) 9 patient set-ups, 5) 19 determining radiation fields, 6) 5 radiotherapy treatment plans, 7) 4 physical/laboratory examination to monitor a patient's condition during treatment, and 8) 10 follow-up evaluations. These items were sent to radiation oncologists in charge of gastrointestinal malignancies in all hospitals (48 hospitals) in Korea to which 30 replies were received (63%). Results : Most of the survey items were replied to without no major differences between the repliers, but with the following items only 50% of repliers were in agreement : 1) indications of preoperative radiation, 2) use of endorectal ultrasound, CT scan, and bone scan for staging work-ups, 3) principles of combining chemotherapy with radiotherapy, 4) use of contrast material for small bowel delineation during simulation, 5) determination of field margins, and 6) use of CEA and colonoscopy for follow-up evaluations. Conclusion : The items where considerable disagreement was shown among the radiation oncologists seemed to make no serious difference in the treatment outcome, but a practical and reasonable consensus should be reached by the committee, with logical processes of agreement. These items can be used for a basic database for the Patterns of Care Study, which will survey the practical radiotherapy patterns for rectal cancer in Korea.

Purpose: The aim of this study was to evaluate the quality of the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency intensive care unit (ICU) in consultation with intervention radiologists and surgeons. Methods: This was a retrospective observational study conducted in an emergency ICU of a tertiary referral hospital. We enrolled consecutive patients who had been admitted to our emergency ICU with major trauma from March 2007 to September 2010. We collected data with respect to demographic findings, mechanisms of injury, the trauma and injury severity score (TRISS), emergency surgery, angiographic intervention, and 6-month mortality. Then, we compared the observed and predicted survivals of the patients. The Hosmer-Lemeshow test and calibration plots by using 10 groups, one for each decile, of predicted mortality were used to evaluate the fitness of TRISS. P-values of greater than 0.05 represent a fair calibration. Results: Among 116 patients, 12 (10.34%) were dead within 6 months after admission to the ICU, and 29 (25.00%) and 38 (32.80%) patients received emergency surgery and angiographic intervention, respectively. The mean injury severity score and revised trauma score were 36.97±17.73 and 7.84±6.75, respectively. The observed survival and the predicted survival of the TRISS were 89.66% (95% confidence interval [CI]: 84.03~95.28%) and 69.85% (95% CI: 63.80~75.91%), respectively. The calibration plots showed that the observed survival of our patients was consistently higher than the predicted survival of the TRISS (p<0.001). Conclusion: The observed survival for the trauma care system of our hospital, in which emergency physi-cians care for major trauma patients in the emergency ICU in consultation with intervention radiologists and surgeons, was higher than the predicted survival of the TRISS.

본 연구는 유아기 자녀를 둔 아버지의 놀이에 대한 국내 연구동향을 분석하고, 추후 유아기 자녀를 둔 아버지의 놀이 관련 연구의 방향성을 제시하여 아버지교육 프로그램 등을 개발하기 위한 기초자료를 제공하기 위한 목적이 있다. 연구 대상은 2001년부터 2020년까지 발행된 학위논문 46편, 학술지논문 25편, 총 71편이다. 분석 결과는 첫째, 1990년대는 관련 연구가 거의 진행되지 않았으나 2000년대 들어서면서 조금씩 증가했고, 2015년을 전·후로 연구가 점차 증가하면서 현재까지 꾸준히 이어지고 있다. 둘째, 연구방법은 양적연구가 대다수이고 그중에서도 상관연구가 주를 이루며, 질적연구나 혼합연구 등은 미흡하여 다양한 연구방법의 적용이 필요하다. 셋째, 연구의 핵심주제를 분석한 결과 아버지의 놀이참여, 놀이성, 놀이신념/인식, 거친 신체놀이/놀이행위 그리고 놀이프로그램 순이었다. 아버지의 놀이와 연관된 관련 키워드 분석 시, 아버지의 놀이 그 자체에 대한 관심보다는 유아와의 연관성을 확인하는 연구가 많았다. 추후 유아기 자녀를 둔 아버지의 놀이가 아버지 본인, 배우자 등에 미치는 다양한 영향력을 확인하는 연구로 확대되길 기대한다. This study analyzes domestic research trends regarding the play of fathers with young children, suggests the directions for future play-related research for such fathers, and provides basic data for developing father education programs. The study subjects are 46 dissertations and 25 academic journals published from 2001 to 2020, totaling 71. The results of the analysis are as follows: First, there were few related studies in the 1990s, but they gradually increased in the 2000s and the research has increased rapidly around 2013-2015 and has been steadily continuing to the present. Second, quantitative research accounts for the majority of research methods. Among them, correlation research is the main part, and qualitative research and mixed is insufficient, so it is necessary to apply various research methods. Third, analysis of the core themes of the study revealed fathers’ play participation, playfulness, play beliefs/ recognitions, rough-and-tumble play/play behaviors, and play programs, in that order. In addition, when analyzing related keywords related to father’s play, there were many studies that confirmed the relationship with young children rather than the interest in the father’s play itself. In the future, this research will be expanded to a study that confirms the various influences of the father’s play with young children on the father himself and his spouse.

Durability evaluations to assess the deterioration of reinforced concrete structures in the present have been considered only individual deterioration factors such as salt damage and carbonation. Also, indoor accelerated experiments have not been able to realize the combined deterioration factors that actually affect real concrete structures. Therefore, in this study, mixing design was proportioned with the various water-binder ratio 0.55 binder compositions corresponding to Type I cement without any supplementary materials(OPC), Type Ⅱ cement with 50% blast-furnace slag replacement (BFS50), TypeⅢ cement with 15% fly ash replacement (FA15), and ternary cement with TypeⅣ cement, 15% fly ash, and 35% slag replacement (BFS35+FA15). And this study is carried out to compare individual deterioration test with combined deterioration test and to investigate the effect of the permeation of deterioration factors such as CO₂ and chloride ion under the combined deterioration environments. After setting up various deterioration factors and levels such as carbonation, salt damage, and the repetition of drying-wetting, items such as carbonation depth, chloride ion penetration depth were evaluated under the combined deterioration environments. The results showed that carbonation depth, chloride ion penetration depth were increased according to the elapsed of ages. Also mixing design with BFS50% and BFS35%+FA15% exhibited higher durability factor than that made with OPC only.

Objectives : To explore the relationship between Percutaneous Transluminal Coronary Angioplasty(PTCA) volume and the associated immediate outcome. Methods : A total of 1,379 PTCAs were peformed in 25 hospitals in Korea between October 8 and December 31 in 1997. Data from 1,317 PTCAs (95.5%) were collected through medical record abstraction. Inter-observer reliability of the data was examined using the Kappa statistic on a subsample of 110 PTCA procedures from five hospitals. Intra-observer reliability of the data was also examined. PTCA success and immediate adverse outcomes were selected as the outcome variables. A successful PTCA was defined as a case that shows less than 50% diameter stenosis and more than 20% reduction of diameter stenosis. Immediate adverse outcomes included deaths during the same hospitalization, emergency coronary artery bypass graft (CABG) within 24 hours after PTCA, and acute myocardial infarction within 24 hours after PTCA. The numbers of PTCAs performed in 1997 per hospital were used as the volume variables. Results : Without adjusting for patient risk factors that may affect outcomes, procedures at high volume hospitals ($\geq200$ cases per year) had a greater success rate (P=0.001) than low volume hospitals. There was a marginally significant difference (P=0.070) in major adverse outcome rates between high and low volume hospitals. After adjusting for risk factors, there were significant differences in procedural failure and major adverse outcome rates between high and low volume hospitals. Conclusions : After adjusting for patient clinical risk factors, the hospital volume of PTCA was associated with immediate outcomes. It is recommended that a PTCA volume per year be established in order to improve the immediate outcome of this procedure in Korea.
