The purpose of this study is to explore EFL college students’ perception of teacher-student (T-S) interaction and student-student (S-S) interaction in an online learning environment. There were 195 participants, enrolled in a real-time online General English course, who were divided into two groups. One group took the course for a 15-week semester, while the other took it for two consecutive semesters. A survey was conducted to identify the preferred types of T-S and S-S interaction. A chi-square test was performed to ascertain the differences in preference between the two groups. Open-ended items were used in the survey to explore the reasons behind the preference for a particular type of interaction. The findings revealed that the groups differed significantly regarding their preference for types of T-S interaction, whereas no significant difference was observed with regard to intensive and intimate paired S-S interaction. The more experienced group was successful in creating a collaborative learning atmosphere and exhibited a strong preference for group-based T-S and paired S-S interaction. The study confirmed that a close relationship exists between students’ perception of online T-S interaction and S-S interaction. The study also offers suggestions for teachers to facilitate meaningful and active T-S and S-S interaction in an online learning environment.
하이네의 그림읽기: 시대의 표상으로서의 예술 - 『프랑스 화가들』을 중심으로 -
진숙영 ( Jin¸ Sukyoung ) 한국헤세학회 2020 헤세연구 Vol.44 No.-
하이네가 파리 망명 당시 쓴 글 『프랑스 화가들』은 하이네의 미술비평이자 저널리즘적인 글이다. 본고는 이 “묘사와 논쟁과 문화철학이 혼재해 있는 하이네의 하이브리드적인 텍스트”가 ‘상호문화성’과 ‘상호미디어성’의 측면에서 중요한 이유 및 융복합적 사고가 요구되는 현재의 독자들에게 매력적일 수 있는 근거를 분석한다. 우선 하이네의 독창적인 저널리즘적인 예술비평의 특성을 시대배경과 연관 지어 조명해보았다. 이어진 세 개의 그림묘사의 예들에서 시대의 표상으로서의 예술의 특징을 확인했다. 들라크루아의 그림 「민중을 이끄는 자유의 여신」은 혁명의 시대정신의 표상으로, 아리 셰퍼의 「실을 잣는 그레첸」은 독일적 민족성인 ‘사색’을 대표하는 것으로, 호라스 베르네의 「유디트와 홀로페르네스」의 유디트는 프랑스의 민족성인 ‘행동’을 대표하는 것으로 묘사된다. 그러나 그림묘사 속 자유로운 연상, 가상의 대화, 진지함과 농담을 자유로이 오가는 하이네만의 독특한 아이러니는 ‘시대의 분열’을 반영하는 하이네의 독특한 문학적 기법으로써, 구축된 이분법을 자유로이 무너뜨린다. 하이네의 『프랑스 화가들』은 기존의 과소평가와 달리 문학과 시대의 상호적인 작용을 반영하는 창의적인 예술비평이라 할 수 있다. Heinrich Heines Französische Maler (1831) ist eine Art von Bericht und zugleich Kunstkritik, die Heine in seiner Pariser Zeit für das deutsche Publikum geschrieben hat. Dieser Beitrag will zeigen, dass “Heine’s hybrid text - a mixture of description, polemics and cultural philosophy” gerade für heutige Leser von großer Attraktivität im Sinne von Interkulturalität und Intermedialität ist. Heines Kunstkritik, die im Stil eines Feuilleton geschrieben ist, ist das Produkt der veränderten Zeit, in der die klassische Kunstkritik ihre Gültigkeit verloren hat. Die Analyse von drei Bildbeschreibungen beweist es: Die Freiheit führt das Volk von Delacroix wird als Signatur der Zeit gesehen, dann Gretchen am Spinnrad von Ary Scheffer als die Repräsentation Deutschlands und des ‘Gedanken’, dagegen die Judith-Figur in Judith und Holofernes von Horace Vernet als Repräsentation Frankreichs, der Revolution und der ‘Tat’. Heine liest in Gemälden der französischen Maler seine eigene Zeit. Dialoge, freie Assoziationen, Ironie, die zwischen Ernst und Scherz frei schwankt, sind wirkungsvolle Methoden, die ‘Zerrissenheit der Zeit’ zu reflektieren. Heines Text kann ungeachtet der Geringschätzung bisheriger Kunsthistoriker, als eine sehr kreative Kunstkritik gesehen werden, welche die zeitgenössischen Medien aktiv rezipiert und die Wechselwirkung zwischen Literatur und Politik der Zeit reflektiert.

<P>There are currently a large variety of wireless access networks, including the emerging vehicular ad hoc networks (VANETs). A large variety of applications utilizing these networks will demand features such as real-time, high-availability, and even instantaneous high-bandwidth in some cases. Therefore, it is imperative for network service providers to make the best possible use of the combined resources of available heterogeneous networks (wireless area networks (WLANs), Universal Mobile Telecommunications Systems, VANETs, Worldwide Interoperability for Microwave Access (WiMAX), etc.) for connection support. When connections need to migrate between heterogeneous networks for performance and high-availability reasons, seamless vertical handoff (VHO) is a necessary first step. In the near future, vehicular and other mobile applications will be expected to have seamless VHO between heterogeneous access networks. With regard to VHO performance, there is a critical need to develop algorithms for connection management and optimal resource allocation for seamless mobility. In this paper, we develop a VHO decision algorithm that enables a wireless access network to not only balance the overall load among all attachment points (e.g., base stations and access points) but also maximize the collective battery lifetime of mobile nodes (MNs). In addition, when ad hoc mode is applied to 3/4G wireless data networks, VANETs, and IEEE 802.11 WLANs for a more seamless integration of heterogeneous wireless networks, we devise a route-selection algorithm for forwarding data packets to the most appropriate attachment point to maximize collective battery lifetime and maintain load balancing. Results based on a detailed performance evaluation study are also presented here to demonstrate the efficacy of the proposed algorithms.</P>

There is increasing interest in examining the contribution of ultra-processed foods (UPFs) to individuals’ diets and the health impact of UPFs. A growing body of evidence indicated that higher UPF consumption is associated with an increased risk of diverse health outcomes. As evidence is emerging, efforts to shift towards limiting UPF consumption have become a relevant and timely topic. In general, observational epidemiologic studies, especially prospective cohort studies, have merit in unraveling the association between dietary intake and health outcomes and food frequency questionnaires (FFQs) have been administered as the most practical method in large-scale epidemiological settings since the 1990s. However, concerns related to the use of the FFQ in UPF classification are raised, especially in Korea where main diets consist of many dishes with combinations of individual ingredients and seasoning. While UPF consumption in Korea gradually increased, however, very limited study on UPF consumption and disease risk is available to date. Thus, this presentation will show the performance of the FFQ to classify UPF consumption of individuals’ diets compared to the 24 HR. We suggest that the FFQ in the Korea National Health and Nutrition Examination Survey (KNHANES) can be an acceptable tool for UPF classification and it is needed to be limited to the purpose of relative comparisons using quantile categorization. This would provide new insights for future use of the FFQ in large-cohort studies that only measure dietary intake with FFQs.

In many studies, negative emotions such as depression / anxiety / irritation are negatively correlated with "learning achievement", ie, higher negative emotions can have a negative effect on academic achievement. In addition, the rapid spread of the Internet and smartphones and the exposure of irrelevant negative content, it causes many psycho-emotional problems in the educational setting and social environment and especially in the case of "anger control disorder" which is shown in various ages including youth recently, it may be caused by lack of adequate control ability on experiences of unexpected or unwanted stressors from outside. Negative Psychological - Methods such as medical approaches or psychological counseling to solve emotional problems require time and money, therefore, this study was aimed to investigate the relationship between preventive and ongoing solutions to these problems are difficult. We investigated that the experience of noninvasive EEG sources can reduce negative emotions that can occur when exposed to external stress and change them into positive emotions. Emotional ontology based emotion rule and emotional response test. Experimental results according to designed method when exposed to external stress, ie external negative stimuli. When experiencing EEG sources, it is desirable to reduce negative emotions and enhance positive emotions rather than to experience EEG sources can be. Therefore, the continuous experience of non-invasive EEG sources that emotional resilience is improved and it is proved to be an effective means to change negative emotions to positive emotions and to maintain positive emotions longer.

In this study, the coupled simulation of fuel injection model and three-dimensional KIVA-3V code was tried to develop of the algorism for predicting the effects of varying fuel injection parameter on the characteristic analysis of fuel injection and emissions. The numerical analysis was done by STAR-CD code in order to calculate the intake air flow, and the combustion characteristics is examined by KIV A-3V code including the conditional moment closure (CMC) model to predict turbulent mean reaction rate. Parametric investigation with respect to twelve relevant injection parameters shows that there is a significant advantage in varying control chamber orifice diameter, needle valve spring constant and nozzle chamber orifice diameter with respect to minimizing the NOx and soot emissions. Consequently, in order to design the fuel injection system for reducing the specific emissions, it seems reasonable to suppose to be optimized the fuel injection system.
