Nocolok 브레이징을 하기 위해서는 플럭스 용액을 접합부 표면에 도포해야 하는데 저농도 플럭스와는 달리 고농도 플럭스는 필요한 부분만 도포해야 한다. 보통 기존의 브레이징로에서는 고농도 플럭스 도포를 수작업으로 하 고 있는데 작업의 비효율성을 초래하고 플럭스 분진 날림 및 열 등으로 인해 작업 환경을 악화시킨다. 그러므로 경제 적이고 효율적인 고농도 플럭스 자동 도포 장치의 개발을 통한 품질 향상 및 생산 단가 저감 등이 절실한 실정이다. 따라서, 본 연구에서는 고농도 플럭스 자동 도포 시스템을 설계 및 제작하였고 이를 직접 브레이징로에 장착하여 자동화 공정으로 개선시켜 기피 작업 해소 및 생산성 향상을 이루었다. Nocolok brazing requires flux at the joining area and low-concentration flux is uniformly spreaded to products to be brazed in a chamber. However high-concentration flux needs to be applied only to a necessary spot. In general, high-concentration flux is manually applied for conventional brazing furnaces, resulting in low production efficiency and harmful environments for workers due to particles and heat etc. Therefore an economical and efficient automatic spreading system needs to be developed. In this study, an efficient automatic spreading system of high-concentration flux was successfully developed and tested with a NBF.

The Fronde and Jansenism have a lot in common. First of all, they both began in the mid-17th century and suffered similar fates in 1653, when the Fronde was subdued by Mazarin and Jansenism pronounced a heresy by the Pope. Second, both were led by a privileged minority. Nevertheless, not much research has been conducted about the relation between the Fronde and Jansenism, although both were an expression of discontentment by the governing class in Paris. To discover the relationship between the Fronde and Jansenism, this paper begins by exploring the political background behind the inception of jansenism, Next, it focuses on the Arnauld family-where Jansenism originated-to show how Jansenism appealed to the ruling class in Paris, particularly to the judges of the Parlement of Paris. Here this paper notes the sense of instability and pessimistic view of humanity that had been widespread among the ruling class of Paris in the early-17th century. Finally, it examines the two Mazarinades published during the Fronde that later were proved to have been written by Jansenist Arnauld d'Andilly, which explains how Jansenists-known to be escapists and believers in the afterlife-thought about and participated in the Fronde.

18세기 프랑스

Until the present the Enlightenment is considered as one of reasons of French Revolution, in this context the 18th Century is refered to as the period of the Enlightenment. But this article will attempt to reconstruct the 18th Century French history that has been distorted and preconceived by the perspective of the Enlightenment and the French Revolution. I trace the concrete course of events which show the jansenist trouble strained after the death of Louis XIV was extened to the political conflict and formed the oppositional ideology. Especially, and differently from other established studies that have focused on the changes revealed since 1750 year, this study extends back to around 1730. It was in this year when the papal bull that condemned the jansenism was proclaimed as a law of the state. At the same time the theological controversy surrounding jansenism spreaded into a political dispute and exploded the political crisis by solidifying the political opposite party and making the common people accede to the public opinion. This political crisis recurred in 1750, 1771, 1787-8. Hence while the scope of the dispute amplified from religion and politics to economics and socitey, sovereignty defined as “absolute and perpetual right” by Jean Bodin moved from the monarch to the nation, paving for a new society.

루이 14세와 절대군주정 : 프랑스 고유의 근대적 경로

This thesis aims at revaluating the achievements of Louis ⅩⅣ and repositioning his reign in a different perspective, which has long been regarded as a model of monarchy. It is since 1980s that the traditional interpretation of Louis ⅩⅣ has been challenged. According to the new interpretation, the ruling of Louis ⅩⅣ was supposed to compromise and coordinate with the local elites by sustaining the traditional hierarchy and not really supposed to accomplish the centralization based on the modem bureaucracy and the taxational monopoly. Accordingly, the driving force of the monarchy was actually networks of nobles based on the hierarchy and the privileges, not really bureaucrats dispatched by the King, and such a social system was directly linked to court society as a core political power. In this regard, the reign of Louis ⅩⅣ should be reinterpreted as a part of the gradual historical evolution, not as a rhetoric of political, administrative revolution. However, we can't deny the achievements of Louis ⅩⅣ such as a huge amount of national documents and statistics produced in that period, the absence of rebellion, taking root of the intendance and the foundation of large-scale standing army. One of the most obvious achievements of Louis ⅩⅣ is that he played a pivotal role for the national integration. He prepared the conditions required for the modem nation state by incarnating the concept of royal sovereignty and conceptualizing the people as an object of ruling. But at the same time, we cannot help but position Louis ⅩⅣ as an object to overcome in the process of building the modem state in the real sense, of which the ultimate goal is the 'nation state'. As a result, we could say that the absolute monarchy of Louis ⅩⅣ ended up making only a 'half success'.

본 연구는 피해자학이라는 사회과학의 교과목에서 거꾸로 학습 방법의 효과성과 학생 특성에 따른 차별적 영향의 검증에 목적을 두고 수행되었다. 2017년 봄 학기에 실시한 피해자학 강의에서 거꾸로 학습과 전통적 강의방식, 두 형태로 수업이 나뉘었고, 일주일에 3시간 강의로 15주 동안 진행되었다. 거꾸로 학습 수업은 2시간 비디오 강의와 1시간의 교실 수업으로, 전통적 강의 수업은 3시간의 교실 수업으로 이루어졌다. 두 수업은 형태만 다를 뿐 배우는 내용은 같았고, 3번의 퀴즈와 1번의 기말고사로 학업성취도를 측정했다. 거꾸로 학습을 수강한 학생들 (N=55)과 전통적 강의방식을 수강한 학생들 (N=34)의 학업 성취도와 만족도를 비교하였다. 거꾸로 학습과 전통적 강의방식에서의 학생들의 학업 성취도와 만족도를 비교하기 위해, 그리고 학생의 특성에 따른 거꾸로 학습의 차별적 영향을 검증하기 위해 ANCOVA와 t-test를 사용하였다. 피해자학을 수강한 학생의 학업 성취도와 만족도를 거꾸로 학습과 전통적 강의방식을 비교하는 방식으로 진행된 본 연구는 거꾸로 학습이 전통 학습보다 학생의 학업 성취도와 만족도 모두를 높이는 것으로 나타났으며 남학생, 저학년 학생 및 학업성취도 부족학생에게 더 효과적임을 나타내고 있다. 거꾸로 학습은 사회과학 분야의 수업에서도 학생들의 학업성취도를 향상시킬 수 있으며, 이 교수법은 각각의 차별적 특성을 가진 학생들에게 효과적인 방식으로 적절하게 변형되어 적용되어야 한다. The purpose of this study was to investigate the effectiveness of the flipped classroom in social science courses and whether, and how, students individual characteristics influenced this effectiveness. We applied flipped learning and traditional learning to a victimology course taught in the spring semester of 2017. The victimology course consisted of 3 hours per week and lasted for 15 weeks. The flipped classroom consisted of 2 hours video lecture and 1 hour face-to-face lecture, whereas the traditional classroom consisted of only 3 hours face-to-face lecture. In both classrooms, teaching materials were identical and students were tested 3 quizzes and 1 final exam. We compared the academic performance and satisfaction of students in the flipped classroom (N=55) to those of students in a traditional classroom environment (N=34). ANCOVA and t-test were performed to compare academic performances and students satisfaction between flipped and traditional classroom as well as the effect of students characteristics in flipped learning. The results showed that students in the flipped classroom performed better and were more satisfied relative to those taught in a traditional classroom. Moreover, the results showed that the flipped classroom was more effective for male students, lower academic year students, and individuals who are poor in academic performance. We concluded that the flipped classroom can improve student performance even for social science courses, and this model should be applied appropriately in ways that are most beneficial for students with different characteristics.
