The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion causing massive side-to-side mass effect which leads to compression of the contralateral cerebral peduncle against the free edge of the cerebellar tentorium. Diagnosis is based on "paradoxical" motor deficit ipsilateral to the lesion associated with radiologic evidence of damage to the contralateral cerebral peduncle. To date, there is scarce evidence regarding KWNP associated neuroimaging patterns and motor function prognostic factors. A systematic review was conducted on Medline database from inception to July 2021 looking for English-language articles concerning KWNP, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research yielded 45 articles for a total of 51 patients. The mean age was 40.7 years-old and the male/female sex ratio was 2/1. 63% of the patients (32/51) suffered from head trauma with a majority of acute subdural hematomas (57%, 29/51). 57% (29/51) of the patients were in the coma upon admission and 47% (24/51) presented pupil anomalies. KWNP presented the neuroimaging features of compression ischemic stroke located in the contralateral cerebral peduncle, with edema in the surrounding structures and sometimes compression stroke of the cerebral arteries passing nearby. 45% of the patients (23/51) presented a good motor functional outcome; nevertheless, no predisposing factor was identified. A Glasgow coma scale (GCS) of more than 3 showed a trend (p=0.1065) toward a better motor functional outcome. The KWNP is a regional compression syndrome oftentimes caused by sudden and massive uncal herniation and leading to contralateral cerebral peduncle ischemia. Even though patients suffering from KWNP usually present a good overall recovery, patients with a GCS of 3 may present a worse motor functional outcome. In order to better understand this syndrome, future studies will have to focus on more personalized criteria such as individual variation of tentorial notch width.

The information and knowledge of modern society in the 2lst century is changing rapidly. Based on this social change, the ministry of education introduced STEAM (Science Technology Engineering Art Music) in 2011 to foster creative convergence talents. Therefore, this study is based on the PBL model that learners participate in the class voluntarily to develop appropriate talents in the 21st century. The combined subjects were English, which is the world's official language, and Science, which is found in almost all the fields with the development of the 4th industrial revolution. As a result, learners could define the problems and solutions during the English class and take part in the group activity actively to obtain the problems and solutions of environmental pollution during the Science class. Through this, learners answered that they had a great understanding of learning (86%), high motivation for learning (100%), improved self-confidence (100%), and improved collaboration and creativity (100%). Unfortunately, this study does not progress actively due to the entrance exams, which still require accurate answers rather than the necessity and effectiveness of convergence education. To foster talents suitable for the present age, more active research should be applied to a range of educational sites.

There is a paucity of research on socialization of novice teachers that has been found to have influence on their career through studies in different subject fields in various regions. This study addresses how novice English teachers perceive their socialization at the first years. It aims to draw implications for novice teacher support for training and professional development. Data were obtained from a questionnaire survey. From the review of the relevant literature, six themes were identified as significant factors in novice teachers' socialization process: relationship with pupils, teaching, rapport with colleagues, support from headteachers, relationship with parents, and expectations from the society. There were 44 questions under six key factors. 99 secondary English novice teachers participated in the survey. The analysis of the gathered responses to each question reveals information on their socialization process to become a secondary English teacher including adaptation challenges for professional development, which have been neglected but are gaining more attention from different stakeholders. This is being increasingly supported in the time of the coronavirus (COIVD-19) pandemic crisis, disruption and recovery. The study is concluded with some implications for research on novice teacher induction, and teacher education policy and practice.

The aim of this study is to consider the possibility of learning polite expressions of English using the mobile application Naver Band. To improve communicative competence, students need to develop sociolinguistic competence as well as grammatical and discourse competence. To be accordant to social context, the roles of the participants, and the purpose of the interaction, students have to make an appropriate utterance. When a hearer has a higher social status and is older than a speaker, or have low levels of familiarity, Korean native speaker tends to use polite expressions. Students need to learn polite expressions of English because English has a different honorific system from Korean. To realize the characteristics and function of polite language is one thing, but to learn it in a real classroom is another. This study attempts to apply the use of a mobile application, which is considered a user-friendly tool for students, into learning polite language using the UK historical drama, Downton Abbey. Two tests were administered to an experimental group that used the mobile application and a control group that used group work. The results of the two tests show that the use of the mobile application has a positive effect on learning polite expressions and is effective as an after-school activity. In an open-ended questionnaire, students tend to identify polite expressions as superior or high-level language forms and separate these forms from practical expressions. It should be noted as well that teachers need to consider instructing in modern English when using a historical drama in the teaching and learning of polite expressions.

This study aims to examine Korean learners' production of American English vowel focused on feature analysis. Specifically, the present study adopts feature analysis so that vowel production is analyzed in terms of vowel features as well as overall segmental accuracy. To this end, 22 Korean college students participated in a production test which contained 11 English vowels /i, ɪ, eɪ, ɛ, æ, ɑ, oʊ, ɔ, ʊ, u, ʌ/. The results revealed that the degree of difficulty varied depending on features; the Korean participants showed higher accuracy for front/back features than for tongue height features and tense/lax features. In particular, the participants had more difficulty producing back vowels and non-high vowels than front vowels and high vowels with respect to tongue height features and lip rounding features. Among the individual vowels, /eɪ/ showed the highest accuracy in feature analysis. On the other hand, /ɑ, ɔ, ʌ/ showed low accuracy with respect to height features and lip rounding features, and high vowels /i, ʊ, u/ showed low accuracy with respect to tense/lax features. As for the correlation between the vowel features, tongue height features and lip rounding features are significantly correlated. Also, tongue height features and tense/lax features showed a strong correlation. Finally, pedagogical implications for teaching English vowels were further discussed based on the findings of the current study.

The purpose of this paper is to analyze educational theories and practices represented in the movie Dangerous Minds. This paper begins by giving the overview of the movie. Then this paper makes an analysis of the pedagogical methods and practices used by the teacher in the movie, which can encourage students to fulfill their academic success and social mobility. The lives of students at risk are transformed through the teacher's beliefs and pedagogical practices based on the constructivism, leading students on a path of selfdiscovery and self-empowerment. What is imperative in the students' lives here is their intrinsic motivation and self-efficacy toward the self and their educational system. By providing constructivist pedagogical paradigms and viewing these media texts within the context of an urban school, this paper intends to introduce educational theories and methods which can create better educational environment for students. In short, this study explores teaching theories and methods represented in the movie based on the constructivist perspectives, which are supposed to fully cultivate the potential of students.

The Bodysonic system was invented on the basis of 'Bone Conduction Theory,' which states that people feel sounds with their whole body. The Bodysonic system is used for L2 (English) learning at Aichi Women's Junior College. In recent years we have developed some unique methodology related to use of the Bodysonic system. In Japan it is difficult for adult L2 learners to acquire the prosody of a foreign language. A language laboratory using the Bodysonic system has been suggested as one way to eradicate such adult L2 problems. The Bodysonic system changes sounds into vibrations. It makes it easy for learners to acquire the prosody of a foreign language because humans can convey information, through their tactile organs. In addition, this system was originally designed to make people relax, so it can also help minimize learner anxiety. The effect of Bodysonic vibrations on language learning has already been proven by some experiments. The Bodysonic system appears to be an ideal teaching method for adult to learn a foreign language.
