Purpose : This study examined the effect of transcranial direct current stimulation (tDCS) combined high intensity interval training (HIIT) on the aerobic exercise capacity of college soccer players. Methods : The subjects of this study were 30 college soccer players. They were divided into a high intensity interval training group combining transcranial direct current stimulation (Group I) and a high intensity interval training group (Group II). Each group had 15 subjects randomly assigned. After receiving general soccer training, each group additionally received high intensity interval training combined with transcranial direct current stimulation and high intensity interval training for 30 minutes 5 times a week for 8 weeks. Their VO2max and 20 meter shuttle run test, Yo-Yo intermittent recovery test were analyzed before the intervention. After 8 weeks of intervention, the above items were re-measured and an intergroup analysis was performed. Results : As a result of comparative analysis of VO2max intake between groups, 20 meter shuttle run test and Yo-Yo intermittent recovery test, a statistically significant difference was found. The high intensity interval training group (Group I) combined with transcranial direct current stimulation showed a significant difference in aerobic exercise capacity compared to the high intensity interval training group (Group II). Conclusion : These results showed that high intensity interval training group combined with transcranial direct current stimulation was more effective for aerobic exercise. Based on this study, this study proposes an effective program for patients as well as elite athletes. In the future, it is necessary to develop an effective transcranial direct current stimulation program and to study how to apply it for various patients.

Analysis of Curriculum Components of Language Teacher Education:Enhancing Academic Knowledge or Developing Professional Skills?

Lee, Yo-An(2010), “Analysis of Curriculum Components of Language Teacher Education:Enhancing Academic Knowledge or Developing Professional Skills?”, Language & Information Society 13, Two of the principal goals of language teacher education are to enhance teachers` academic knowledge and to develop their teaching practices. Yet, there is a paucity of empirical studies to verify how these goals are realized at actual curriculum of teacher education programs. The present study investigates curricula of language teacher education in order to identify how these dual goals are addressed across programs at the curriculum level. First, the analysis of required courses of 30 randomly selected programs shows that there are too small a number of language education courses to address relevant topics and issues with a sufficient depth. Furthermore, linguistics and education have figured most prominently in academic content across curricula, although linguistic courses outnumber education courses considerably. Second, a detailed case study of one teacher education program looks into the relationship between programmatic features behind its curriculum and the students` evaluation of them. It is found that, while the course works are designed to develop students` conceptual capacity for their independent decision-makings in their classrooms, students are more concerned with whether and to what degree given courses reflect their classroom realities. Implication for curriculum designers and further studies are discussed.

Burak Yoǧurtçuoǧlu,Çaǧrı Damar 대한초음파의학회 2021 ULTRASONOGRAPHY Vol.40 No.4

Purpose: The aim of this study was to compare the acoustic radiation force impulse elastography (ARFI-e) values of the renal cortical parenchyma in children with acute glomerulonephritis (AGN) and healthy children, and to determine a cut-off point for the diagnosis of AGN. Methods: This prospective study included 30 children with biopsy-proven AGN and 30 healthy children. All the children underwent renal ARFI-e measurements. Values were obtained from the upper, middle, and lower zones of the right kidney parenchyma. A total of nine ARFI-e measurements (three from each zone) were made. Statistical analyses were conducted of the mean elastography values (MEVs) of the children in both groups. Results: In the patient group, the MEVs measured from the upper, middle and lower zones of the right kidney were 3.42±0.42 m/s, 3.45±0.45 m/s, and 3.39±0.39 m/s (average, 3.42±0.34 m/s), respectively. In the healthy control group, the MEVs measured from the upper, middle, and lower zones of the right kidney were 2.85±0.63 m/s, 2.85±0.68 m/s, and 2.86±0.66 m/s (average, 2.85±0.57 m/s), respectively. The MEVs in all zones were significantly higher in the patient group than in the healthy group (P<0.001). The cut-off values determined to predict AGN in the upper, middle, and lower zones of the kidney were 2.74 m/s (sensitivity, 96.67%; specificity, 46.67%), 2.71 m/s (sensitivity, 96.67%; specificity, 53.33%), and 2.81 m/s (sensitivity, 93.33%; specificity, 56.67%), respectively. Conclusion: The ARFI-e technique can be considered as a non-invasive, easily applicable, auxiliary method for the early diagnosis of AGN.

문화역량 모델을 위한 학제적 접근 : 구성주의 인식론과 기호학을 중심으로

박여성 한국문화교육학회 2009 문화예술교육연구 Vol.4 No.2

With drastic decomposition of traditional social structures, the acquisition of competencies, wherever we work, is getting more significant role in individual as well as in vocational lives. So, in this paper we outline an trans- and interdisciplinary approach to the key-competency related researches, based on constructivist epistemology and cultural semiotics. It deals with the stratificational structures of cultural competency- modellings, their logical demands for modelling, and the sustainability of competencies as well as the action indices. This descriptive apparatus should include the hierarchy of cultural competencies, the media-competency and literacy applied to the educational curriculum. These syncretisms in the research of HRD(Human Resource Development), which are becoming increasingly obvious in the era of globalization, are to be systematically described and explained by the equally syncretistic discipline of metatheory which reformulates the relevant contributions of related sciences and connects them into a unified framework, i.e. into the Cultural Semiotics. 1990년대 이후 전통적인 사회구조가 급격히 해체되면서, 계획되지도 않고 예견될 수도 없는 상황에 적절하게 대처하고 행위하는 능력, 즉 역량(Kompetenz)의 습득은 개인은 물론이고 기업의 생존에도 더욱 중요해진다. 부단히 변화하는 노동환경에서 행위능력을 갖춘 역량인(Kompetenzmensch)을 확보하고 정치 경제 사회 문화적 이익에 부합하기 위해 스스로를 조직하는 평생학습이 요청되는 시점에서 유럽연합(EU)은 1996년을 "평생학습의 해"(Jahr des lebenslangen Lernens)로 선포했고 사민당(SPD)과 녹색연합당(Bündnis 90/Die Grünen)의 위임을 받아 독일연방의회도 2000년 5월 "만인을 위한 평생학습"을 천명했다. 이때 학습문화와 역량발달에 관한 기술모델이 세계화 과정 속에서 제기되는 '역량'(Competencies)의 학제적 연구에 부응하는지 점검할 필요가 있다. 이에 본고에서는 독일어권에서 제안된 교육학의 역량모델을 구성주의 시각에서 진단하고1) 역량 일반을 문화, 예술 및 매체 차원에서 조명하는 기호학적 모델의 단서를 고민해 보았다.

전압비교기를 이용한 AB급 연산증폭기의 슬루율 개선에 관한 연구

김요섭,손상희 청주대학교 산업과학연구소 2016 産業科學硏究 Vol.33 No.2

In this paper, we introduce a circuit which has improved power consumption and slew rate by adding a voltage comparator on the structure of the class AB rail to rail folded cascode OP amplifier. Using a voltage comparator, bias voltage near to VDD is applied in charging and discharging time and so high voltage is transferred to the output load. Therefore, proposed class AB rail to rail folded cascode OP amplifier circuit has high slew rate and low power consumption. From the simulation results of slew rate, we know that slew rate of proposed circuit is improved from 2.5V/us to 12V/us comparing to the conventional circuit. That is the reason why voltage comparator transmits voltage near to the value of VDD to the load stage. From the simulation results of power consumption, we know that power consumption of proposed circuit is improved from 1.2mW to 0.5mW comparing to the conventional circuit. Proposed class AB rail to rail folded cascode OP amplifier is designed and simulated by using the TSMC 0.18um 1-Poly & 6-Metal CMOS process.
