Advanced oral squamous cell carcinoma (SCC) is a possible risk factor for myiasis, a parasitic infestation of vital tissue of humans or other mammals by dipterous larvae (maggots). Oral myiasis is a rare entity, and is mostly associated with various medical and anatomical conditions, such as neglected mandibular fracture, lip incompetence, cerebral palsy, poor oral hygiene, suppurative lesions, and cancerous wounds. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threating hemorrhage. The aim of the present article was to highlight the occurrence of oral myiasis in association with squamous cell carcinoma and also to highlight the treatment and preventive approaches for such cases. A literature search was performed using MEDLINE for articles published in English relating to the occurrence of oral myiasis in oral SCC. Our search revealed 6 reports on myiasis associated with oral SCC. The surgical debridement of infected tissue with the removal of maggots is the treatment of choice in most cases of oral myiasis.

ICT는 교육의 효과를 증대시킬 수 있는 강력한 도구라는 이유로 교육에서의 활용이 중시되어 왔다. 그 중 Excel은 뛰어난 수식 계산과 논리 판단 기능을 갖추고 있고 다양한 종류의 계산을 할 수 있다는 점에서 수학과에서 그 가능성이 제시되어 왔다. 그러나 기존의 연구는 대부분 중 고등학교 수학과 통계단원에 중점을 두어 이루어 졌다. 그러나 함수의 사용이나 영어로 된 명령어는 초등학교에서 활용하기에는 무리가 있었다. 이에 본 연구에서는 초등학교에서 Excel을 활용하여 수학문제를 해결하는데 있어 단순 계산보다는 문제해결을 위한 사고에 중점을 둔 문제해결수업모형을 개발하여 적용하고 결과를 알아보았다. 연구 결과 문제를 해결하는데 있어 엑셀을 이용하였을 때가 필기보다 문제를 해결하는 성공률이 더 높고, 문제해결 시간이 더 단축된 것을 알 수 있었다.

It has been claimed that Korean mid-vocalic voiceless unaspirated lax stops are phonetically realized with voicing throughout the oral closure phase. Acoustic measurements were undertaken to examine the claim with four Korean native speakers using /$V_1CV_2$/ words where the vowel ($V_1\;=\;V_2$) was /i, a, u/ and the C was voiceless unaspirated lax stops /p, t, k/. Findings: (1) During mid-vocalic stops /k/ and /p/ the vowel /u/ was accompanied generally by a significant increase in voice cessation time as percentage of the oral closure interval (PCT) than the vowel /a/, regardless of subjects, whereas in mid-vocalic alveolar stop /t/ the effects of vowels on PCT were subject-dependent, (2) The effects of vowels on PCT were significantly greater in mid-vocalic /k/ than /p/, regardless of subjects, (3) The mean PCT, averaged across six tokens, ranged from 17% to100%, giving overall mean 61% in which the standard deviation was ${\pm}30$, and (4) Overall % of the total of mid-vocalic unaspirated lax stops were produced with a substantial period of devocing and voicing lag. Considering these results, it is difficult to agree with the existing claims that Korean voiceless unaspirated lax stops are phonetically realized with voicing throughout the oral closure phase. Other phonetic variables, including the durations of pre/post-stop vowels, voice onset time, voice cessation time, and the duration of oral closure, were measured.

The aim of this study is to investigate college students' opinion on participation in media education. The research question is as follows: first, what is the college students' perceptions who participated in media education? Second, what are the differences among the perceptions of college students who participated in media education? To answer these research questions, we used Q-methodology, which is more useful in organizing subjectivity types and opinions of students, both in explaining and sorting of data by characteristic and personal opinion. As a result, two types were found; type 1 is the active participation type that focuses on the active participation in media education as a productive tool and teaching method, as well as diminishing the current controls and restrictions on its use in education. On the other hand, type 2 is the growing adaptive type and is positive for the future development of media education in a transitional role, while they think that current media education for college students is not qualitative yet, a productive tool and the quality of the information message is lacking, and so on.

While the field of mathematics education strives to promote equitable mathematics learning and identifies it as a core instructional practice, less is known about its effective enactment. As teachers' teaching practices are dependent on their views and beliefs, this study investigated 133 elementary pre-service teachers' (PSTs') interpretations of diverse learners' learning experiences and proposed accommodations for them as reflected in their lesson planning process. Findings showed that PSTs came up with some strategies that are often suggested in teacher education literature, such as using multiple modes of representation and various grouping strategies. However, their responses were generic in nature rather than specific to diverse learners. Also, it was noted that many PSTs' interchangeably referred to the English Language Learners (ELLs), struggling learners, and culturally diverse learners, inferring that they thought that culturally diverse students must have been ELLs and that ELLs or culturally diverse students must have been weaker students in math. We found that the PSTs used their own frames while filtering and discarding information about diverse student populations to develop instructional plans, rather than based on the results of assessments of learning. We suggest that it is the critical first step to unwrap PSTs' unproven assumptions to better equip them for working with all of their future students.

The purpose of this study was to examine the effectiveness of gamification in nursing practice for undergraduate students, as well as to explore the use of gamification in nursing education. This study is a systematic review of RCTs evaluating the effectiveness of gamification in nursing practice for undergraduate students. A total of 7 articles were identified in a search of PubMed, Cochrane Library, and Embase, and the additional databases were CINAHL (in English) and RISS (in Korean) between September 28, 2022 to October 5, 2022. Themes related to the environment and personal behaviors between 2002 and 2021 were extracted. The intervention themes were blood transfusion, postoperative pediatric nursing, postoperative hemorrhage and brain trauma nursing, basic and advanced life support, disaster nursing, and neonatal resuscitation. The primary outcomes were knowledge in five studies, satisfaction in one study, and competency in one study. The secondary outcomes were satisfaction in three studies, confidence in two studies, performance in two studies, skills in two studies, and self-efficacy, motivation, professional attitude, cognition, gameful experience, and affective response in one study each. Therefore, gamification interventions can be utilized in nursing practice education instead of traditional teaching methods such as lectures and face-to-face clinical practice.

The purpose of this study was to seek strengths and weaknesses from analyzing Korea and U.S. science textbooks in terms of general structural features, contents, cognitive levels of questions and the purpose of questions used in science textbooks. This provided insight into improvement of textbooks that can effectively assist teaching and learning. To investigate organization of unit in textbooks in-depth, the evolution unit was selected and scrutinized as one example. The results showed that the number of pages, activities, vocabulary words, and vocabulary lists are considerably different between Korean and the U.S. Commonly, U.S. textbooks were more laden with information and lacking in coherence than those of the Korean textbooks. The findings on the cognitive levels of questions showed that the majority of questions in both nations are concerned with knowledge. However, the difference between the two nations is great in the ratios of analysis, synthesis, and evaluation questions. Questions are concentrated in review section (45% of Korean and 60.6% of U.S.) in textbooks. It suggested that well-planned questions in a review section can provide the basic guidance for strength in a science classroom.

"The Waste Land" is Eliot's best known poem. It was first published in 1922 and became a famous poem in modem poetry by the 1940's. The poem is a statement of his personal experience with spiritual crisis, this simple outline is complicated and universalized by being set within the structure of 'the Fisher King legend'. The fisher King legend was studied by Miss Weston in From Ritual to Romance and Sir James Frazer in The Goldon Bough which traced the vegetation myths. It explained the cycle of the seasons in relation to the death and rebirth of a god. The god died in the winter with the death of the vegetation and was reborn in the spring with the rebirth of the vegetation. Sir James Frazer reaced these ancient rituals within the Christian world. He indicated that the death and rebirth of Christ falls within the pattern of this ancient ritual. Also Miss Weston transformed that ancient ritual into Christian terms, and connected it with the Quest for the Holy Grail. Eliot used not only the title, but the plan and a good of the important symbolism of the poem from these two books. "The Waste Land" is a difficult one because of the numerous interruptions in the narrative. On the superficial level, the story covers a 12-hour period in a day. It is also in "the stream of consciousness." It might be called the internal monologue; that is, "the free association of ideas in the mind of the narrator," Eliot experiments with both the idea of time and with the stream of consciousness, He employs a number of quotations and allusion from the Classic literature. So, his technique in "The Waste Land" consists of the juxtaposition of the present with mythcism and religious symbolism derived from the past. The structure of the poem is built out of the contrasts in time. The poem illustrates his conception of the past as an active part of the present. "The Waste Land" has "a symphonic structure" composed of five parts, which are linked by the repeated themes. The theme is the death and salvation of the Waste Land. It is drawn from the Fisher King myths. Moreover, he has absorbed into the structure of this poem the language, phrases, and associations of other writers. It gave the poem the universality both of theme and of pattern. Also, his intricate and fine techniques added the universality to the poet's personal material. At last, the verse pattern of the poem follow the same basic structure as the thematic patterns. Again in symphonic style, the verse varies from section to section. The interruption of real time is associated with the flow of consciousness. Though the poem is a complex structure, there are the interweavings of a great deal of ideas into a simple, brief statement. By these poetic techniques the poem manages to have good harmony and unity between the thematic pattern and narrative structure. "The Waste Land" therefore, became the greatest poem in the 20th century modern world.
