Background: The purpose of this study was to provide epidemiological and histological data of thyroid cancers in Togo. Materials and Methods: This was a retrospective cross-sectional study of cases of thyroid cancers diagnosed from 2000 to 2014 (15 years) at the pathology laboratory of the Sylvanus Olympio Teaching Hospital of $Lom{\acute{e}}$. All cases of review of a thyroid sample (biopsies, surgical specimens) were collected from the data records of that laboratory. Results: Thyroid cancers represented 1.1% (7930cases) of all cancers registered during the study period. Mean age was $45.4{\pm}0.3$ years and the proportion of females was 78.3%. We identified 92.4% carcinomas and 7.6% lymphomas. Carcinomas were well differentiated in 80 cases and were dominated by the papillary type (47 cases). Metastasis was observed in 13% of patients. The pTNM classification evaluated in 18 cases showed a predominance of grade I (13 cases). Lymphomas were dominated by lymphoma diffuse large B-cell (5 cases). Conclusions: This study is the first global standard for thyroid cancer pathology in Togo. The high frequency of follicular form suggests an unrecognized iodine deficiency. The improvement of the technical platform of the LAP (immunohistochemistry) will increase the diagnosis of rare forms of thyroid cancer.

There has been a growing enthusiasm in Korea for the early education of English as a foreign language (EFL). The present study examined the validity of the Critical Period Hypothesis in terms of the Universal Grammar (UG), in three different types of learning contexts - first language (L1), second language (SL), and foreign language (FL) learning contexts. While previous research findings in L1 and SL learning contexts suggest that UG principles and parameters are accessible to language learners only for the early years of lifetime, this article argues that their results - and even the methods - cannot be applied to EFL settings and that independent studies on the EFL context are, required. It also proposes the recent UG notion of functional categories as the most appropriate subject in the discussion of Korean EFL learners' access to UG. Findings on foreign language contexts, including the author's own, strongly indicate that UG is not sensitive to learners' starting ages in FL settings. If young children in FL contexts cannot develop their interlanguage grammar based on UG, the existing teaching methods for young children should be revised.

Objectives: Dislocation of the temporomandibular joint may occur for various reasons. Although different invasive methods have been advocated for its treatment, this study highlights the value of non-invasive treatment options even in chronic cases in a resource-poor environment. Materials and Methods: A seven-year retrospective analysis of all patients managed for temporomandibular joint dislocation in our department was undertaken. Patient demographics, risk factors associated with temporomandibular joint dislocation and treatment modalities were retrieved from patient records. Results: In all, 26 patients were managed over a seven-year period. Males accounted for 62% of the patients, and yawning was the most frequent etiological factor. Conservative treatment methods were used successfully in 86.4% of the patients managed. Two (66.7%) of the three patients who needed surgical treatment developed complications, while only one (5.3%) patient who was managed conservatively developed complications. Conclusion: Temporomandibular joint dislocation appears to be associated with male sex, middle age, yawning, and low socio-economic status, although these observed relationships were not statistically significant. Non-invasive methods remain an effective treatment option in this environment in view of the low socio-economic status of the patients affected.

The purposes of this study were to develop STEAM teaching materials about 'world of small organisms' unit on elementary science education and to apply lesson using them for the 5th and 6th graders. Compared to other STEAM programs studied previously, the STEAM teaching materials of this study includes students' STEAM, teachers' guide, story-telling books and multimedia teaching aids consisted of practical resources to manage STEAM lessons. The whole program was designed from multidisciplinary integration to extradisciplinary integration through activities making creative products, meanwhile each period had discretionary S, T, E, A, M factors specifically. To examine the effects of integrated lesson on scientific knowledge, process skills, and affective domain, the study subjects were divided into two groups. The experimental group was composed of 69 individuals participated in STEAM lesson, while students of the control group were 67 individuals learned through general learning methods. The developed STEAM teaching materials affected significantly on scientific knowledge and affective domain of elementary school students, but process skills were not increased significantly. In the present study, therefore, the approach applying STEAM education could be suggested as alternative learning materials or supplementary teaching materials at the field of small organisms in elementary science sufficiently.

The purpose of this study was to analyze the results of teachers' self-evaluation on their health teaching behaviors, then to furnish the basic data to be able to improve teachers' health teaching activities and the educational issues on the education of teachers. To put above aims into practice, these were required: 1. Are there any differences in the results of self-evaluation on health teaching behaviors factors by teachers? 2. Are there any differences in the results of health teaching self-evaluation whether he/she take P.E as major of study in-serviece training period? 3. Does it have any influence on the results of health teaching self-evaluation whether he or she completed on the job training for the school health? 4. Are there any differences in the results of health teaching self-evaluation by sex and career? To carry out a research for this purpose, the factors of health teaching self-evaluation were divided into the clearness of the procedure, the active interaction, the variety of the ways showing the contents, and the individualization of the procedure. Then a questionnaire form, consisting of 28 specific inquires to evaluate health teaching behaviors, was delivered and conducted by 450 teacher of the elementary school in Kyungki-do. The analysis of data was done by SPSS; producing mean and standard deviation and they were inspected statistically to compare the evaluation levels and find out the differences by teachers' personal variables. The conclusion were as follows: 1. In the self-evaluation level of teachers' health teaching behaviors, teachers showed 68.23 point as are percentile distribution. And it was in order of a school-nurse(71.68), an athletic teacher(67.29), and a class-room teacher (65.66). Score obtained by teacher was statistically significant difference (p〈.001) 2. In the factors affecting to teachers' health instruction, “active interaction” showed the highest score(18.55), “variety of ways showing the contents”(17.38), “clearness of the procedure” (16.70), and “individualization of the procedure” (15.59). In the analysis of the differences by teachers, according to factors, there were significant differences in “active interaction”, “variety of the ways showing contents”, “clearness of the procedure”(p〈.001). 3. Self-evaluation score for graduates from Dept. of P. E in Teachers' collage was not significant difference compared with other majors(p〉.05). 4. Teachers receiving health education was significantly higher self-evaluation score than that of teachers not-receiving health education (P〈.01). 5. Self-evaluation score of female teacher was significant difference compared with that of male teacher (p〈.001). 6. Career (working duration) did not influenced to self-evaluation score on health teaching behaviors (P〉 .05). On the basis of the conclusion of this study, the next are suggested: First, the further studies to make use of the results of health teaching behaviors and to examine the effect are needed. Second, the further studies to examine the relations between academic achievement and teachers' major(a school-nurse, an athletic teacher, and a class-room teacher) are needed. Third, the following studies to improve health teaching by both teachers' self-evaluation on health teaching behaviors and students' evaluation of teachers, and to find out more effective health teaching, are needed. Fourth, Health education for pre-service training course and On-the-Job training program are need the effective factors on the teachers' Health teaching obtained from this study.

The purpose of this study is to examine the effects of mentoring in enhancing the professionalism of low-experience science teachers on their general teaching and science teaching efficacies. The mentoring for low-experience science teachers was conducted on 24 science teachers with less than three years of experience over a nine-month period between April and December, 2016. The questionnaires developed by advanced researches were modified and used to test the teachers' general teaching and science teaching efficacies. As the result of a pre-test, the mean science teaching efficacy score was 3.02 points. In particular, the mean science teaching self-efficacy score was 2.86 points and the mean science teaching outcome expectancy score was higher at 3.17 points. In the domain of science teaching outcome expectancy, the mean for female teachers was higher than that of male teachers, and the mean for middle school teachers was higher than that of high school teachers in every domain. However, this result is not statistically significant. The results of a post-test showed that the mean science teaching efficacy score of mentee teachers increased to 3.08 points over the pre-test. In particular, the mean science teaching self-efficacy score was 3.11 points and the mean science teaching outcome expectancy score was 3.04 points in the post-test. This presents that the mentoring training conducted was effective in improving the science teaching efficacy of mentee teachers.

The purpose of this study is to analyze whether there is a financial incentive effect by analyzing the difference of educational performance between the specialization department students who receive financial support and the students who do not receive support. This study collected survey data of 334 students including 290 students who were financially supported and 44 students who were not financially supported. Through the collected data, frequency analysis and descriptive statistics analysis were performed on the general characteristics of the subjects. T-test was conducted to analyze the difference of teaching & learning performance between students with financial support and those who did not, and then the difference analysis by grades was F-test. The average value of the subjects' teaching & learning satisfaction scores was 2.99, and the result was higher than that of the female students. The higher the age, the higher the grade, the higher the grade, the higher the financial support students were. The average of teaching & learning achievement composition items of the survey subjects was 2.27, and it was found that male students, older students, and students who received financial support had higher average of teaching & learning outcomes than students who did not receive financial support respectively. Students who receive financial support have higher teaching & learning satisfaction and outcomes than students who are not financially supported. The longer the period of financial support, the older the better, and the male students are more satisfied with the teaching & learning, the better the teaching & learning.

The purpose of this study is to analyze changes of competency observed in teaching of pre-service science teachers through the teaching evaluation and reflective journal writings on science class during the period of student-teaching at high school. To do this, we videotaped all the science classes of six pre-service teachers participating in this study, evaluated their class teachings, and collected moving video clips recorded in their classes, reflective journals, interviews, instructional materials, and teaching evaluation they have provided. From the "Standards for teaching evaluation of science instruction" developed by Korea Education Curriculum and Assessment, sixteen evaluation elements were selected and used for the analysis. According to our results, all preservice teachers show improvement of teaching performance in most of the class evaluation elements as the number of science classes increases. They presented the lowest improvement in the 'to design meaningful learning program,' which was one of the sixteen elements. However, there are substantial individual differences in the pre-service teachers' teaching competence on each evaluation element. Although they thought that 'understanding of scientific concepts' is the most important part of a science class in the beginning of student-teaching training, they showed changes in recognition that 'interaction and respect' and 'managing student behaviors' are also important in the end. They have recognized that writing a reflective journal, based on the video clips recorded in class and teaching evaluation, helps improve their teaching competency. In addition, improvement in teaching competency has influence upon career-orientation towards the school teacher in the future.

In this study, the researcher aimed to increase productive reflection of pre-service elementary teachers through meta-analysis of their own reflective journals. The meta-analysis activities are expected to enhance their learning effectively as a kind of self-assesment. During 8 week simulation teaching, 26 pre-service teachers kept individual journal writing and the meta-analysis activities were implemented twice (after the 3rd and 8th week). Right after the first meta-analysis, the pre-service teachers' productive reflection increased clearly. However this would not guarantee the effect would last long time period. By analyzing 8 week reflective journals, reports on meta-analysis activities and small group interview, this study shed light on practical ways of enhancing reflective teacher education.
