본 연구에서는 인공지능 모델에 따른 한국 프로야구의 승패 예측 분석에 관한 연구를 했다. 승리할 팀과 해당 팀의 최종 리그 순위를 예측했고, 사용자의 편의를 위해 웹사이트도 구축했다. 각 1·3·5이닝 별로 가장 정확도가 높으면서도 오차가 적은 모델을 최적 모델로 선정해 승·패 결과를 예측했고, 이를 토대로 순위표를 작성했다. 결과표는 2020년 개막인 5월 5일부터 8월 30일까지의 예측 결과를 바탕으로 작성했다. 기아타이거즈가 아닌 다른 구단끼리의 경기는 실제 결과를 사용했다. 머신러닝 모델은 KNN과 AdaBoost가 최적 모델로 선정되었으며, 실제 순위와 비교해 본 결과, 경기가 진행될수록, 예측 결과의 순위 오차가 점점 작아지는 것을 확인했다. 딥러닝 모델은 89%의 정확도를 기록했고, 머신러닝 모델과 마찬가지로 경기를 진행할수록 예측 결과 순위 오차가 작아지는 것을 확인했다. 실험 결과는 한국 프로야구 승·패 결과 예측뿐 아니라 다양한 분야에서 사용할 수 있을 것으로 사료된다. 방송국에서 야구 경기를 중계하는 중 이닝별로 인공지능 알고리즘이 예상한 승·패 여부를 중계화면에 띄울 수 있다. 시청자들에게 새로운 흥미를 일으킬 수 있을 것이고, 나아가 구단의 감독들이 이닝마다 데이터를 분석해 경기 중 유동적으로 승리하기 위한 전략을 세울 수 있을 것으로 기대된다. In this study, we conducted a study on the win-loss predicton analysis of korean professional baseball by artificial intelligence models. Based on the model, we predicted the winner as well as each team’s final rank in the league. Additionally, we developed a website for viewers’ understanding. In each game’s first, third, and fifth inning, we analyze to select the best model that performs the highest accuracy and minimizes errors. Based on the result, we generate the rankings. We used the predicted data started from May 5, the season’s opening day, to August 30, 2020 to generate the rankings. In the games which Kia Tigers did not play, however, we used actual games’ results in the data. KNN and AdaBoost selected the most optimized machine learning model. As a result, we observe a decreasing trend of the predicted results’ ranking error as the season progresses. The deep learning model recorded 89% of the model accuracy. It provides the same result of decreasing ranking error trends of the predicted results that we observe in the machine learning model. We estimate that this study’s result applies to future KBO predictions as well as other fields. We expect broadcasting enhancements by posting the predicted winning percentage per inning which is generated by AI algorism. We expect this will bring new interest to the KBO fans. Furthermore, the prediction generated at each inning would provide insights to teams so that they can analyze data and come up with successful strategies.

임태원,홍후조 이화여자대학교 교육과학연구소 2021 교육과학연구 Vol.52 No.3

본 연구는 지속적인 학교의 자율성 확대에 따라 교육과정 실천가이자 개발자로서 자리매김한 교사의 역할에 주목하여 교사의 교육과정 재구성의 특성과 촉진 요인, 저해 요인을 질적 메타분석을 통해 탐색하였다. 이를 위하여 2012년부터 2021년까지 국내 등재 학술지에 게재된 사례연구 12편을 분석 대상으로 선정하였으며, 선행연구를 토대로 설정한 분석틀을 적용한 분석 결과는 다음과 같다. 첫째, 교육과정 재구성의 특성으로 가장 두드러지는 재구성의 범위는 주제 중심 재구성과 수업 방법 중심 재구성으로 확인되었다. 교사들은 교육과정을 재구성하기 위하여 학습 내용을 재구성하였으며 내용의 재배열, 추가, 대체, 생략, 축약하는 방법을 사용하였다. 둘째, 교사의 교육과정 재구성을 촉진하는 요인은 교사 요인과 환경 요인으로 대별되었다. 교사들은 교육과정 재구성 동기로 교사로서의 가치관과 신념에 영향을 받았으며, 학습자의 흥미 유발과 학습 동기에 대한 관심이 교육과정 재구성을 촉진하였다. 환경 요인으로는 교사학습공동체의 지원과 집단지성의 활용이 가장 두드러지게 나타났다. 셋째, 교사의 교육과정 재구성을 저해하는 요인은 교사 요인, 환경 요인으로 종합하였으며 추가적으로 학습자료와 관련한 내용이 확인되었다. 교사는 교육과정의 재구성이 개인의 교육과정 역량에 의존하는 데 따른 부담과 자신감 결여를 보였으며, 학습자료인 교과서 중심의 수업 문화가 재구성의 자율성을 제한하는 요인으로 확인되었다. 이 외에도 업무 과중, 학교 문화, 평가의 경직성 등이 환경 요인으로 분석되었다. 끝으로 위와 같은 연구 결과를 토대로 교사의 교육과정 재구성을 지원하고 어려움을 해소하기 위한 향후 연구 방향과 제도적 차원의 개선 방안을 제언하였다. This study focused on the role of teachers as curriculum designers and practitioners, and it explored the characteristics, facilitating factors, and impeding factors of curriculum reconstruction for teachers. To achieve this, this study selected 12 case studies reported in journals in Korea from 2012 to 2021 as objects of analysis. Results may be summed up as follows. First, this study has found out how themebased reconstruction and instructional method-based reconstruction are characterized by curriculum reconstruction. To reconstruct the curriculum by teachers in detail, this study reconstructed learning content, and used methods to rearrange, add, replace, omit, and abbreviate the content. Second, teacher factors and environmental factors facilitated the curriculum reconstruction for teachers. Teachers were influenced by teachers' values and beliefs such as motivation of curriculum reconstruction, and the learner's interest in learning facilitated curriculum reconstruction. This study has shown that the support of a teacher learning community and the use of collective intelligence were the most prominent environmental factors. Third, teacher factors and environmental factors had impeded the teachers' curriculum reconstruction in various ways. Teachers were burdened and lacked self-confidence due to their reliance on the individual curriculum competency of curriculum reconstruction, and this study has found that the textbook-centered instructional culture as learning material compromised the autonomy of reconstruction. In addition, heavy workload and evaluation structure were analyzed as environmental factors. Based on these findings, the researchers suggested the necessity of research performance to explore the facilitating factors of curriculum reconstruction in depth and devise a method for removing impeding factors.

저자들은 상어 간유를 과량 복용하고 기침, 호흡곤란을 주소로 내원한 48세 여자 환자에서 방사선 소견과 기관지 폐포 세척액 검사를 통해 급성 지방성 폐렴으로 진단하고 스테로이드에 불응하는 경과를 취하자 우측 전폐 기관지 폐포 세척술을 시행하여 폐 병변과 증상의 호전을 보인 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Acute lipoid pneumonia is uncommon condition of the lungs that results from the aspiration of vegetable, animal, or mineral oils. Shark liver oil (so called Squalene) is taken as a traditional remedy in some Asian countries, and is used widely also in cosmetics. It results in foreign body type inflammatory reaction of the lung and can show various clinical presentations from asymptomatic incidental finding to severe pneumonia leading to acute respiratory failure. Although many cases have been reported, severe lipoid pneumonia requiring steroid or whole lung lavage for treatment is rare. We experienced a case of acute lipoid pneumonia of 48 year old female with dyspnea and cough caused by regular ingestion of large amount Shark liver oil, treated by whole lung lavage. We reported this case with a brief review of related literatures.

The purpose of this study was to clarify that scintigram was a more effective method than radiogram in the early detection of periapical lesion. Periapical lesions were produced artificially by the opening of the pulp chambers of the lower right 3rd and 4th premolars in 6 dogs. The serial bone scintigrams using 99m-Tc-MDP and periapical radiograms were taken weekly. The uptake counts of the 99-Tc-MDP in the experimental side were compared with those in the control side. The periapical radiograms were interpreted with the joint evaluation by three dental radiologists. The following results were obtained; 1. The radioactivity in the experimental side was increased at the 1st week except one animal in which the radioactivity was increased at the 2nd week. 2. It was observed that increasing amount of radioactivity per week was prominent from the 1st day of experiment to the 1st week, and the 3rd week to the 4th week. 3. The radiographic evidence of the periapical lesions was observed at the 3rd week and became more apparent at the 4th week. 4. Histologically, proliferation of blood vessels and infiltration of chronic inflammatory cells were observed at the 1st week and osteoblasts were found after the 3rd week.

Type I diabetes is caused by destruction of the pancreatic beta cells responsible for insulin-secretion. It can be induced by the drugs alloxan or streptozotocin (STZ). Both an increase in reaction oxygen free radical species and a decrease in the antioxidant defense mechanism lead to the increase in oxidative stress in diabetes mellitus. Oxygen radicals scavengers are effective in preventing diagetes in animal models. Experiments were conducted by two system. The Sprague-Dawley rats were treated with STZ intravenous injection after oral administrated Betula's extract and quercetin for a week, and were administrated them for a week. In vitro, Betula's extracts and quercetin showed a tendency towards inhibition of free radical oxidation in all. In vivo, Betula's extracts group exhibited suppression morphologic change in pancreatic islet compare quercetin group on light microscopy. The Betula's extract significantly inhibited formation of MDA compared to the STZ-induced diabetic group in pancreas.They also significantly inhibited formation of Phosphatidylcholine hydroperoxide(PCOOH) compared to the STZ-induced diabetic group in pancreas and plasma, which considered defense against destruction in beta cells. The protection by Betula's extracts may be due to scavenging of deleterious and highly reactive free radical which is generated by STZ. In streptozotocin-induced diabetic rats, the effect of Betula's extract are greater than that of quercetin. Based on this result, we concluded that Betula's extract has the ability to effectively suppress in vitro and in vivo oxidation, thereby providing additional evidence for their potential beneficial type I diabetes.

Cleft lip and palate is the most common malformation in the craniofacial region. The patients with cleft lip and palate have functional problem such as, speech, feeding and respiratory as well as esthetic problem. So, treatment should be done by multidiciplinary team approach. The role of pediatric dentist in the team is advicement for feeding method, guidance of normal growth, caries control and preventive orthodontics. In cleft lip and palate patients, maxillary arch after cheiloplasty is usually collapsed by excessive tension of the scar. This collapse increase the difficulty of later orthodontic treatment. Therefore, the maxillary arch segments should be moved and retaind to normal position as soon as cheiloplasty is done to reduce the need and difficulty of orthodontic treatment. This concept is called by the early orthopedic treatment in cleft lip and palate. Also, this orthopedic appliance works as feeding applince to normal feeding and weight gain We reported two cases of early orthopedic treatment with favorable result in complete bilateral cleft lip and palate patients after cheiloplasty. Patients showed normal weight and their maxillary arch widths were increased.
