Seungjeongwon Ilgi["承政院日記"], the Diaries of Royal Secretariat of the Joeson Dynasty is the most massive compilation of records in Korean history. Medical records in Seungjeongwon Ilgi have been studied but the procedures of clinical discussion[議藥] have not yet been studied. In this paper, main agents of clinical discussion, formation of participant doctor system, particularity of clinical discussion in Royal Court and problems derived from it will be discussed. Main agents of clinical discussion were court doctors[內醫], royal doctors[御醫] and participant doctors[議藥同參]. The king himself decided ultimately as a matter of form. Head of the Medical Dpt. of the Palace[藥房都提調] was in charge of attending to king, but head of the court doctor[首醫] led the actual discussion of deciding treatment. The Medical Dpt. of the Palace[內醫院] was divided into three sectors-court doctor division, acupuncture doctor division and participant doctor division. Palace doctors payed a great attention to avoid serious error. This tendency led them occasionally to passive management. Sometimes aggressive treatment is needed in the course of treating disease, but palace doctors tended to choose slow and gradual methods. It induced minor conflict between palace doctors and participant doctors from outside palace, because doctors from outside palace subordinated effectiveness. Their opinion had not been always recognized by court doctors. However, their role was meaningful because they provided flexibility to the rigidity of clinical discussion in the palace. It is important to evaluate clinical records in Seungjeongwon Ilgi["承政院日記"]. If we have broader eye on the clinical procedure in the palace, we can estimate the value of the contents more objectively and accurately.

The current risk assessment system do not reflect workers' various opinion. However, the worker actually are in the center of work field and are exposed to accidents. In this regard, this study suggests enhanced risk assessment by 'safety circle discussion' on workers' hand. The self-administered surveys on supervisors and workers were done for the effect analysis of the safety circle discussion. According to the question investigation, even though the current risk assessment causes difficulties in preventing accidents by unsafe behaviors, the worker-oriented safety circle discussion establishing measures for risk factors of each work type will be able to prevent accidents more effectively. Also, it can positively contribute to safety health awareness, industrial accident prevention, accurate recognition on risk factors, improving safety facilities/work conditions, workers' compliance to safety health rules. Lastly, most respondents agreed that it is necessary to form organic relationship through circle discussion and deriving safety inspections that workers participate.

The study aims to reveal the differences in the factors influencing portal news and news site application usages on smartphones in regard to political discussion networks, news use across multiple media platforms and news genre consumption. The results demonstrate that those factors affected both types of application usages in a different manner when controlling for demographics. The more participants conversed politics with homogeneous networks, the more they used portal news on smartphones. Conversely, the more political discussion with heterogeneous networks, the more they used news site application on smartphones. The more frequently Internet and mobile phone were employed for news source and the more soft news genre was consumed, the more the portal news application was used. However, the more frequently traditional and social media were employed for news source and the more hard news consumed, the more news site application was used. The findings imply that portal news application users may increase their likelihood of soft news consumption using Internet and mobile phones for political discussion with close social relations, while news site application users may increase their likelihood of hard news consumption using traditional and social media for political discussion with distant social relations.

In the trend toward globalization, cross-cultural teams in organizations are becoming more and more common. In particular, the influence of China and Western Europe on the global economy is getting increased. With this trend, it is important to understand cross-cultural characteristics for group decision making in managerial environments. This study aims at analyzing cross-cultural differences between China and Western Europe in light of the effect of group discussion in group decision making. An experiment simulating a decision of a car purchase was conducted. A total of 48 subjects (24 Chinese and 24 Western Europeans) assigned in decision groups were asked to judge relative importance ratios of nine factors affecting their purchase decisions using the AHP program developed for the experiment. Three dependent variables (consistency, satisfaction, and consensus) were measured. Chinese were slightly more consistent than Western Europeans in discussion-involved group decision making. In terms of decision satisfaction, Western Europeans were more satisfied with discussion-included decisions than discussion-excluded decisions. Chinese, on the contrary, did not show a significant difference. There was no significant difference between two cultures in decision consensus.

본 연구는 수학적 사고를 토의를 통해 언어로 표현함으로써 타인과의 의사소통을 통한 반성적 사고를 유발하는 구성주의적 토의식 학습이 수학에 대한 태도와 수학 학업 성취도에 효과가 있는가를 살펴보았다. 연구 문제를 해결하기 위해서 서울 시내에 위치하고 있는 초등학교 3학년 1개반(30명)을 실험집단으로하여 구성주의적 토의식 학습을 하고, 다른 한 학급(30명)은 비교집단으로 하여 일반적인 수학학습을 6주 동안 시행하였다. 그 결과 다양한 수학적 상황과 의문점들을 토의에 의해 해결해 가는 학습 방법, 즉 자신의 사고를 수학적으로 의사소통해 나가는 구성주의적 토의식 학습은 수학에 대한 태도 중 자아개념과 교과에 대한 태도를 긍정적으로 변화시켰으며, 교과에 대한 학습 습관 중 자율학습과 학습기술 적용에 있어서 학생들을 긍정적으로 변화시키는 데에 효과적이다. 또한 구성주의적 토의식 학습은 일반적인 수업보다 학업성취도면에서 더 좋은 결과를 보였다. 그러나 본 연구가 3학년의 30명 재적의 한 개 반만을 대상으로 하여 학생들이 보인 결과를 분석한 것이므로 통계적으로 좀 더 유의미한 결론을 얻기 위해서는 다양한 학년과 다양한 환경의 학생들의 결과를 알아볼 필요가 있다.

본 연구에서는 실험 수업에 참여한 예비교사들의 반성적 논의에서 나타나는 수업의 요소와 논의의 연계성을 바탕으로 하는 반성의 수준을 분석하고자 하였다. 연구를 위해 실험 교실을 운영하고 있는 예비교사들의 수업 후 논의과정을 분석하였다. 반성적 논의의 분석틀은 수업의 계획-실행-결과의 과정상의 흐름을 반영하기 위해서 수업의 목적, 수업지식, 학습자의 반응을 범주로 삼았고, 각 범주의 요소는 선행 연구와 예비교사들의 논의에서 추출하였다. 연구 결과 예비교사들은 수업의 목적과 학습자 반응에서는 개념이해, 과학적 기능 요소를, 수업지식은 교수법과 내용표현지식의 교수 전략에 대한 반성을 많이 진행하였다. 그러나 탐구나 흥미 요소의 논의는 적었고, 각각의 개념을 명시적으로 사용하는데 어려움을 겪었으며, 수업 모형이나 이론적 내용을 이용한 논의가 부족하였다. 또한 여러 요소의 내용이 서로 연계되면서 논의가 진행되기 보다는 각각의 요소에 대한 단일의 논의가 더 많이 나타났으며, 연계가 일어나는 논의의 다양성도 제한적이었다. 연구 결과를 통하여 예비교사들의 수업전문성 발달을 위한 효과적인 반성적 논의를 위해서는 보다 다양한 요소가 논의에 포함되어야 하며, 이러한 요소들이 수업에 흐름에 따라 연계될 필요가 있음을 제언한다.

This research is a survey study on students' attitude toward a class employing small group discussion and presentation by the method of free-listing. Participants in this study were students who registered in the course of Mathematical Logics and Writing during 2011 and 2014. Senior students who took the course of theory of mathematics education previously usually registered the course. The class for this course used to be designed as a class adopting group discussion and presentation. Main theme of this research is not to demonstrate some theories or hypothesis on teaching and learning, but rather to inquire students' attitude toward a class employing the constituents first and then through analyzing the results of this study to find practical ideas and strategy for design and implementation of a class which brings cultivation of students' understanding, communication and moreover writing in mathematics. Since the survey was given in the $8^{th}$ week of this class, participants of this research could be expected to have more concrete idea for positive or negative aspects of the classes employing these constituents. We compared both research results of 2011 and 2014 to view any changes in students' attitude. Research results are follows. Students began to think that group discussions and presentation bring out better learning to them. Not to give students psychological burden of discussion and presentation, instructors need to provide comfortable atmosphere through arranging suitable grouping and enough time for discussion. Moreover, simple evaluations criteria for group discussions and presentation should be well structured and more concrete guides for them are required to make students to feel comfortable and to concentrate on the given subject for discussion.
