A methodology to predict the output performance of small hydro power using treated effluent in wastewater treatment plant has been studied. Existing plant located Kyunggi-Do were selected and the output performance characteristics for these plants were analyzed. As a result, it was found that the developed mode? in this study can be used to analyze the output characteristics for small hydro power in wastewater treatment plant. Additionally, primary design specifications such as design flowrate, capacity, operational rate and annual electricity production were estimated and discussed.

The atypical choroid plexus papilloma(CPP)is a new category of choroid plexus tumor recently added in the 2007 WHO classification of tumors of the central nervous system. We report the case of a 64-year-old female patient with atypical CPP of fourth ventricle. The patient presented with a 2-month history of dizziness and gait disturbance. Imaging studies showed a large tumor in fourth ventricle. We did suboccipital craniotomy with tumor removal. Pathologic study revealed atypical CPP. Based on our knowledge, up to now, this patient is the first atypical CPP case of fourth ventricle in Korea.

머신러닝 알고리즘 기반 초등예비교사의 실과 비대면 온라인 수업 만족도 예측 요인 탐색

이철현(Lee, Chul-hyun) 한국실과교육학회 2021 한국실과교육학회지 Vol.34 No.1

이 연구의 목적은 교육대학교 실과 비대면 온라인 수업의 만족도를 조사하고, 머신러닝 알고리즘을 기반으로 만족도에 영향을 미치는 요인의 중요도 및 개별 예측 요인의 의존성을 탐색하는 것이다. 이를 위하여 실과교육 관련 비대면 온라인 강좌를 수강한 교육대학교 1~4학년 학생 331명의 데이터를 수집하여 분석하였다. 수집된 데이터에 대하여 기술 통계를 통해 온라인 수업 만족 예측 요인과 만족도 수준을 분석하였고, 5종의 머신러닝 알고리즘을 적용하여 산출된 머신러닝 모델 성능 및 예측 변수의 중요도를 탐색하였다. 또, 예측 변수에 대한 부분 의존 도표 및 개별 조건부 기대치를 산출하여 학습 만족도에 대한 개별 예측 변수의 의존성을 살펴보았다. 그 결과 K-최근접 이웃과 랜덤 포레스트의 성능이 가장 우수한 것으로 판단되었고, 상호 작용과 학습 동기의 중요도가 상대적으로 높게 나타났다. 또, 예측 변수의 영향이 학습 만족도에 대체로 비례함을 알 수 있었다. 이 연구를 통해 얻은 결론은 다음과 같다. 첫째, 매체 효능감, 교육 지원 서비스, 동영상 강의 품질에 대한 최소한의 만족을 유지하도록 수업의 각 주체가 노력해야 한다. 둘째, 수업의 각 주체는 상호 작용, 자기주도성, 학습 동기의 수준을 지속적으로 향상시킬 수 있도록 주의를 기울여야 한다. 셋째, 교수자는 양질의 실습 환경을 제공하고, 실습 과정의 문제와 질문에 적극적이고 신속하게 대응해야 한다. 넷째, 교수자는 예외적 학습자를 파악하여, 이들에게 적절한 수업 처방을 제공해야 한다. The purpose of this study is to investigate the satisfaction level of non-face-to-face online classes related to Practical Arts Education at the University of Education, and to explore the importance of factors affecting the satisfaction and the dependence of individual predictive factors based on machine learning algorithms. To this end, the data from 331 students in the first to fourth grades of the University of Education who took non-face-to-face online courses related to practical arts education were collected and analyzed. For the collected data, the factors predicting online class satisfaction and learning satisfaction were analyzed through descriptive statistics, and the machine learning model performance and the importance of predictive factors calculated by applying five types of machine learning algorithms were explored. In addition, the dependence of individual predictive factors on learning satisfaction was examined by calculating partial dependence plots and individual conditional expectation for predictive factors. As a result, it was judged that the K-nearest neighbor and the random forest had the best performance, and the importance of interaction and learning motivation was relatively high. In addition, it was found that the influence of the predictive factors was generally proportional to the learning satisfaction. The conclusions obtained through this study are as follows. First, each subject of the class should make efforts to maintain minimum satisfaction with media efficacy, educational support services and the quality of video lectures. Second, each subject in the class should pay attention to continuously improve the level of interaction, self-directedness, and learning motivation. Third, instructors must provide a high-quality practice environment and respond actively and promptly to problems and questions in the practice process. Fourth, instructors must identify exceptional learners and provide them with appropriate instructional practices.

The purpose of this study was to investigate the sport participation comparison men with women in during leisure time. The results from this study will provide basis data necessary to develope sport activity program for adults. The subjects in this study were 457 adults in largest cities. The data were analyzed using t-test, chi-square, discriminant analysis with the SAS program. The results were follows; First, the intensity of the motivation in adult sports participation was showed downward heath oriented type, hobby and recreation oriented type, family oriented type, self-developing, social oriented type. The woman of participation in sport activities was showed heath oriented type, family oriented type more than that of men. Second, adult sports participation was influenced the intensity of the family and friend`s encouragement. women was influenced spouse`s encouragement, and the perceived athletic ability was the strongest predictor of adult sports participation for both men and women. third, for sport participants, many adults participated in secondary involvement more than primary involvement, and primary involvement was lots of men more than women. Fourth, women perceived barriers more than men in sports participation. Men perceived barriers in the order of time, economic, social barriers, women perceived barriers in the order of economic, time, social barriers.

『搜神記』와 『搜神後記』에 나타난 문화콘텐츠 원형 연구

이철진(Chul-Jin Lee) 한국엔터테인먼트산업학회 2017 한국엔터테인먼트산업학회논문지 Vol.11 No.7

본 연구에서 문화 콘텐츠 원형을 老人, 복숭아, 承負觀으로 나누어 살펴보았다. 老人에서는 노인 인물 성격을 신선형 노인, 不老不死형 노인으로 나누어 볼 수 있는데 공통적으로 노인은 神仙이다라는 결론에 도달하게 되었다. 복숭아에서는 『搜神記』와 『搜神後記』에 복숭아를 神仙세계의 道要之物로서 仙話의 중요 題材로 등장시키고 있으며 現代醫學에서도 복숭아를 노화를 방지하는 無病長壽의 식품으로 알려져 있다. 따라서 복숭아 축제를 여는 지방자치단체에서는 본고에서 언급한 복숭아 문화 원형을 새로운 문화 콘텐츠 개발의 원천자료로 활용하길 바란다. 承負觀에서는 선인선과, 악인악과라는 圖式的인 단계를 뛰어넘는 高次的 勸善懲惡을 설명하는 이론이 承負觀이라고 설명하였다. 承負觀은 현대사회에서 일어나는 因果關係나 先報後讐, 先讐後報, 先親後敵, 先敵後親이라는 인간관계 等 複雜多端한 관계망을 설명하는 最適의 이론이라는 점을 알아야 할 것이다. 이러한 이론을 현대 문화 콘텐츠에 접목시킨다면 무한한 가치의 발현효과를 얻을 수 있을 것이라 思料된다. 결론적으로 『搜神記』와 『搜神後記』는 한국문화콘텐츠에 기초 자료로서 무한한 자양분을 제공할 수 있을 것이다. This studied the forms of cultural contents by categorizing them into elder, peach, and Seungbukwan. In Elders, the characteristics of the elder could be divided into taoist hermit elder, non-aging and immortal elder, and ghost type elder; commonly, they all came to conclusion that ‘elders are Taoist hermit’. In peach, Sushinki represents the peach as a gift from the Taoist hermit world; peach is also known as healthy and long-living food that prevents aging in the world of modern medicine. As this, we ask for the local governments that open peach festival to use the peach culture form mentioned in this article as the source of new contents development. In Seungbukwan, it indicates that Seungbukwan is the most appropriate thing that clearly explains the complicating theory of good and evil, a situation where that goes beyond the schematic theory that ‘good man are blessed and wicked are punished’ and good man is punished or wicked is blessed. If such theory is applied to modern cultural contents, there will be infinite usable value. In conclusion, ‘Sushinki’ and ‘Sushinhuki’ will be able to provide nourishing element to Korean cultural contents as an infinite basic data. I believe that this article will be a little help.

화두의 本意는 인간의 의식. 무의식을 포함한 인간심리에 대한 전통적 학문이며 치료술이라고 말할 수 있을 것이다. 김성동의 『曼陀羅』 ‘병속의 새’라는 화두를 중심으로 화두의 本意를 탐구하고 나아가서 현대인의 심리치료 활용, 학습 응용, 육체치료 응용, 치매치료 응용 等으로 살펴보았다. 그리고 南宋시대에 출현한 화두라는 말은 우리가 일상생활의 대화 속에서 내뱉는 단어로서 그칠 것이 아니라 현대인의 심리명상 치료, 학습 치료, 치매치료, 육체치료에 응용할 수 있는 무한한 寶庫가 된다는 점을 闡揚하는 데 本稿의 의의를 두고자 한다. Mandara is derived from the idea of exploring the Hwadoo in the Ganhwaseon of Seonjong. In Seonjong, they used the Hwadoo as a guide or method for teaching disciples. And the essence of inquiry is the enlightenment and the most important basis for enlightenment is the mind. Hwadoo is a traditional study of human psychology including the consciousness and unconsciousness of human and it can be said as a therapy. This paper explores the true meaning of Hwadoo by focusing on Hwadoo called “the bird in the bottle” of “Madara”, Kim Seong Dong’s novel. In addition, we examine several applications of psychotherapy, learning, physical therapy and dementia treatment for modern people.
