Objectives : The purpose of this study is to investigate the change pattern and the leading factors of delirium in the palliative ward from 2 weeks before to the end of life. Methods : From October 2015 to August 2017, a retrospective chart review was conducted on the final 180 patients of 207 patients with terminal cancer patients at the Inha University Hospital. Clinical records were collected during palliative care hospitalization. Patients were diagnosed with three subtypes of delirium through the Richmond Agitation Sedation Scale and the Nursing Delirium Screening Scale, which were evaluated daily. Results : The prevalence of delirium 13 days before death was 46%, of which 18.3% were hyperactive subtypes, 13.8% were hypoactive subtypes, and mixed subtypes were 13.8%. And hyperactive delirium gradually decreased with the approach to the end of the day, and the mixed subtype gradually increased until 4 days before the end of life. Of the patients, the day before death, 86.9% were diagnosed with delirium. In multivariate analysis, hematologic malignancy was associated with a lower rate of delirium at the end of life than gastrointestinal cancer. Overweight was associated with hyperactive, mixed, and hypoactive delirium. Conclusions : Most palliative care patients experienced delirium at the end of life. Overweight was considered as a protective factor that reduced the all subtypes of delirium at the end of life. Further prospective studies are needed to reveal the prevalence of terminal delirium, and their risk factors.

Purpose: No attempt has been made to identify the relationship between the study characteristics and citation rates of articles published in the Journal of the Korean Orthopaedic Association (JKOA). This study classified the study characteristics of articles in the JKOA and analyzed the relationship between the study characteristics and citation rates. Materials and Methods: A cohort study was conducted on all articles published from February 2001 to December 2015. Three independent reviewers classified the articles according to the article type, material, time of the study, design, clinical categories, number of authors, and number of cases. The citation numbers of each article by other journals were taken in January 2020. Univariate analyses were conducted to assess the effect of each characteristic, and multivariate linear regression analysis was performed to analyze the overall relationship between the characteristics and the citation rates. Results: A total of 1,640 articles were published from 2001 to 2015, and 724 articles were cited more than once. The articles published in 2009 had the highest average number of citations. Original articles had the highest citation rates, followed in descending order by surgical techniques and reviews, instructional course lectures, and case reports (p<0.001). Among the case reports, articles dealing with general trauma scored significantly higher average citations (mean=1.5, p=0.006). Among the original articles, articles on general orthopedics had the highest citation rates, followed in order by clinical articles and experimental articles. Among the clinical articles, epidemiologic studies (mean=5.0, p<0.001) and studies on the spine (mean=1.7, p<0.001) recorded significantly higher citation rates than the others. Conclusion: Of all the articles published in the JKOA from 2001 to 2015, articles dealing with general trauma had the highest citation rates among case reports. Among the original articles, epidemiologic studies and studies concerning the spine were cited significantly more than others.

The purpose of this study is to explore four-year old children's peer culture. During free choice play time, various activities and interaction patterns were observed and analyzed to understand the characteristics of peer culture. The results of this study showed two main peer culture patterns. First of all, peaceful peer culture in which children maintained close relationships based on mutual respect were found. Also conflictive peer culture in which children had negative relationships with other children, such as vertical, discriminative and neglected relationships were observed.

시대적 변화에 따른 경력성공의 관점이 변화하고 있지만 다수의 연구들은 창업과 취업을 분리하여 연구되어 왔다. 또한 환경의 변화뿐만 아니라 개인 가치관의 변화에 따라 평생 직장의 개념이 사라졌으며 전 생애에 걸친 학습의 필요성이 대두 되고 있다. 학습의 형태는 기존의 지식을 전달하는 형태에서 다양하게 변화해왔다. 교실 수업의 형태는 팀활동과 미디어 활용을 중심으로 변화하고 있으며 교실 밖 수업에서는 자율적인 동아리 활동이나 커뮤니티의 참여 등을 통해 역량을 향상시키는 기회를 제공하고 있다. 개인의 경력은 인생에 걸친 학습과 일에 관련된 경험 및 행동과 연관된 태도로부터 발생한다. 이러한 경력을 이끌어가는 태도는 새로운 환경속에서 즉각적인 요구를 받아들이는 적응학습과 새로운 행동 및 지식을 유발하는 생성학습, 그리고 상호작용 패턴 인식을 통해 새로운 시도를 하는 전환학습을 지속적으로 일으킨다. 또한 이러한 무형식 학습들은 취업과 연계 될 뿐만 아니라 창업의도에도 긍정적인 영향을 줄 수 있다. 본 연구는 자기주도성과 가치지향성을 척도로 하는 프론티언 경력태도가 창업의도에 영향을 미치지 확인함으로서 기존의 취업역량과 연결시켜왔던 연구에 새로운 시사점을 제시하고자 한다. 또한 무형식학습 활동을 매개변인으로 투입하여 학습 과정에서 자연스럽게 발생하는 학습의 효과를 확인하여 변화된 교육형태의 중요성을 확인하는데 의의가 있다. 이에 더해 스마트미디어를 활용하는 능력인 스마트미디어 리터러시와 팀 학습을 지향하는 팀학습 선호도를 조절효과로 보아 분석함으로서 스마트미디어활용 학습과 팀학습의 형태로 변화하고 있는 교육 현장의 특성을 함께 확인하고자 한다. 이를 위해 2019년 3월부터 6월까지 교육과 경력 환경의 변화의 중심에 서있는 대학생들을 대상으로 설문조사를 실시하여 이를 분석하고자 한다.

In the actual classroom the so-called flow learning is able to motivate the students through face-to-face feedback, and to meet their needs for educational achievement. By contrast, the so-called e-learning method falls short of the satisfactory level of real-life interaction, which makes many learners drop out or give up on their learning. In order to better the e-learning environment, this study presents a dialogue-based feedback system that improves the flow learning of the learners' in the classroom. This newly developed system was applied at the actual school. The result is that the experimented group improved its flow learning, compared with the controlled group. In the former group, each individual showed some consciousness of objective and challenge following the concrete feedback. That is to say, this system enhances the attitude of an active participation and induces the flow learning, thanks to the dialogue-based feedback and the sustained interest in learning. In conclusion, the significance of this study lies in suggesting the direction of a new learning method development in the e-learning environment.

본 연구는 우리 나라의 성인들이 자신의 초중등 학교 시절 경험하였던 학교 과학교육에 대해 어떤 종류의 즐거운 혹은 괴로운 기억들을 현재까지 갖고 있는가를 탐색하였다. 성인들은 오래 전 경험하였던 매우 인상적인 활동이나 장면들을 통해 학교 과학교육을 기억할 것이고, 이러한 기억은 그들의 학교 과학교육에 대한 전반적인 태도에 결정적인 역할을 할 것이다. 따라서 성인들의 학교 과학교육에 대한 이러한 기억들을 살펴보면, 학교 과학교육의 특징을 이해하고 장기적으로 학교 과학교육을 보다 즐거운 경험의 장으로 만드는 데 도움이 될 것이다. 본 연구는 소규모의 설문 조사를 통해 이루어졌으며, 설문 대상은 대구지역의 30-50대 성인 88명이었다. 설문은 현재 과학과 관련된 특정한 직업을 갖고 있지 않은 사람을 대상으로 하였으며, 설문에서 응답자들은 자신들의 초중등 학교 과학교육을 받으면서 가장 즐거웠던 기억과 가장 괴로웠던 기억이 구체적으로 무엇이며 이러한 경험은 초중고 어느 때이었는가를 응답하였다. 성인들이 가장 즐거웠던 기억으로 지적한 것은 실험 실습 활동(65.9%), 야외학습 활동(19.3%) 등으로 전통적인 교실수업 이외의 활동이 약 86%로 나타났다. 그리고 효과적인 교실수업, 교사의 인성적 특징, 과학전람회 참가 등의 경험을 언급한 경우도 부분적으로 있었다. 성인들이 가장 괴로웠던 기억으로 지적한 것은 따분한 교실수업(51.1%), 실험 실습 활동의 부정적인 측면(28.4%) 등으로 나타났으며, 부분적으로 과다한 숙제, 교사의 인성적 특징, 야외학습 활동, 과학수업의 부재 등을 지적한 경우도 있었다. 또한 전체적으로 즐거웠던 기억은 국민학교 시절의 경험에서(56.8%), 반면 괴로웠던 기억은 고등학교 시절의 경험에서(44.3%) 많이 나타났다. 특히, "개구리 해부 실험" 의 경우, 7명이 가장 즐거웠던 기억으로 8명은 가장 괴로웠던 기억으로 언급하여 매우 상반된 견해를 나타냈다. 따라서 동일한 활동일지라도 학생들에게는 매우 상반된 경험으로 작용하게 되며, 이 경우 생명체에 대한 과학실험의 윤리적 문제와 이에 대한 갈등을 분명하게 드러냈다.

The goal of this paper is to measure and compare the performance of solar heat pump for school classroom heating. To accomplish the goal, solar heat pump with alumium roll bond type evaporator and indoor heat exchanger(condenser) was built and fully instrumented with thermocouples and pressure transducers etc. The test results showed that the COP and capacity of R-134a($CF_3CH_2F$) were higher than those of R-12($CF_2Cl_2$). The solar heat pump system for room heating was designed to show the best efficiency that the room temperature make $18{\sim}20^{\circ}C\;and\;23{\sim}25^{\circ}C$ in Seoul during November, December, and January.
