The purpose of this study is to evaluate the views and experiences of the prospective chemistry teachers (PCTs) about the use of graphic organizers (GOs) supported with interactive PowerPoint presentation technology in teaching electrochemistry concepts. Ten GOs were developed and a pair of slides for all of them which contains partial and complete versions of the GOs was constructed. Participants of this study consisted of two different study groups. The preliminary trial of the study was carried out with four senior PCTs who have previously taken both an Electrochemistry course and an elective course concerning graphic organizers. Data from the first group of the study were collected by semi-structured interview and the experiences of the first group regarding the difficulties experienced during traditional electrochemistry teaching (didactic lecture) were examined. The second study group was eight PCTs who were in the fifth semester and were taking the Electrochemistry course while the study was being undertaken. In the last three weeks of the Electrochemistry course in the second study group, the course was taught with GOs supported with interactive PowerPoint presentation technology, and then the views of them were taken by a written opinion form. At the end of the study, three themes emerged regarding the experiences of the PCTs for the traditionally taught electrochemistry course. These are "difficulties", "inadequacy", and "not being beneficial". It was also concluded that the PCTs thought that the use of GOs supported with interactive PowerPoint presentation technology in teaching electrochemistry could enhance the comprehension and motivation of students.

Abstract In this study, it was aimed to examine the educational problems of basic education students migrating from Syria encountered in the schools. The research study group involved 37 Syrian students, 4 school managers and 18 teachers who were willing to participate to the research from four different secondary schools. The study group was chosen according to accessibility criterion. The data were collected through interviews. Therefore, the data was analyzed according to the qualitative methods. In the analysis of data collected by using face to face interview technique and semi-structured interview form, the content analysis method was used. According to the research results, it was determined that Syrian students have a language problem, especially during their education. They had sufficient knowledge of the Turkish language to manage their daily lives, however, academically the knowledge was concluded as insufficient. The main problems occurring among Syrian students are communication skills and adaptation. Main causes of these two problems are the differences between the ethnic origin among the Syrians students and the integration and communication with Turkish students. The Syrian students can be divided into two group as Syrian Kurdish or Syrian Arab. Both groups indicate that it is hard to communicate with each other due to the language difference. Furthermore, the Syrian girls expressed that they have more difficulties in being accepted and making friends, which causes the feeling that they are left alone. The findings of the research reveal that Syrian parents do not visit the school and that their skills of understanding and speaking Turkish are far behind their children's ability to understand and speak Turkish. According to the students 'views, the main reason for their parents' not visiting the school is the language problem. According to the data obtained from the interviews conducted by the administrators, guidance teachers and class teachers of the schools, it has been determined that some Syrian students have problems in integration during school, lack of motivation for the classes, and a more introvert student profile compared to other students. On the other hand, it was also stated that it was uncommon that Syrian students were included or had caused for any improper circumstances at school or were involved in any disciplinary case.

Preparatory Work

Nadat Hitler in oktober 1939 beslist had een aanval in het Westen te ondernemen, werden in Keulen twee studiegroepen opgericht, die het toekomstig bezettingsregime van België en Nederland moesten voorbereiden. Er was een studiecommissie die geleid werd door de toekomstige leider van het Duits Militair Bestuur in België, Regierungspräsident Reeder, en daarnaast bestond een geheime studiegroep die de Sondergruppe Student werd genoemd. Deze bijdrage belicht het voorbereidend werk van de leden van deze studiegroep op het gebied van handel, industrie, recht, Volkstum en cultuur in België. De groep legde een grote belangstelling voor de Flamenfrage aan de dag en trok daarbij lessen uit de ervaringen met de bezetting van België tijdens de Eerste Wereldoorlog. Ofschoon er van diverse zijden in Duitsland werd op aangestuurd, hebben zowel de 'commissie Reeder' als de Sondergruppe de wederinvoering van de bestuurlijke scheiding van het Vlaams en Franstalig landsgedeelte, één van de 'verworvenheden' van het Vlaams activisme uit 1914-18, beslist afgewezen. De bijdrage laat ook de tegenstellingen zien die in Duitsland bestonden op het gebied van de beïnvloeding (ten voordele van Duitsland) in de te bezetten gebieden. ________ A German network in the preparation of the Militärverwaltung (Army administration) in Belgium (1939-1940)After Hitler had decided in October 1939 to carry out an attack on the West, two study groups were set up in Cologne in order to prepare the future occupational regime of Belgium and the Netherlands.  The future leader of the German Army Administration in Belgium, President of the Government Reeder chaired the study group, and in addition there was a secret study group called the Sondergruppe Student (Special Student Group).This contribution illuminates the preparatory work of the members of this study group in the area of trade, industry, law, Volkstum (nationality) and culture in Belgium. The group demonstrated a lot of interest in the Flamenfrage (Flemish question) and in doing so drew lessons from the experience of the occupation of Belgium during the First World War.Although people from various quarters in Germany aimed for the reintroduction of the governmental separation between  the Flemish and French speaking parts of the country, one of the 'achievements' of Flemish activism from the period of 1914-1918, both the 'Reeder committee' and the 'Sondergruppe' definitely dismissed it. This contribution also demonstrates the contradictions present in Germany in the area of influencing the territories to be occupied (in favour of Germany).

Medical Interest

The national or local lockdowns in response to COVID-19 forced education systems to rapidly shift from in-person to distance learning. The hasty transition undoubtedly imposed tremendous challenges on teachers, students and distance learning infrastructure. The purpose of this study was to investigate how high school science teachers who had previously been trained in flipped-learning and advanced educational technology through the Science Teaching Excites Medical Interest (STEMI) program perceived their transition to distance learning during this pandemic. In this study eleven teachers were interviewed with a semi-structured interview guide. Data were analyzed using the deductive-inductive content analytic approach. Our results indicated that teachers reported having more confidence in using technology for teaching online due in part to their participation in the STEMI program. They also reported internet access as one of the most significant barriers, both for students and teachers. While some teachers thought that students may feel more in control of learning due to absence of time and place limits with distance learning, others may struggle to stay engaged without the classroom support they would normally have received. Teachers generally experienced increased workloads and harder work–life balance with online teaching. In spite of the unforeseen challenges, the pandemic situation afforded teachers with opportunities to adopt different technology in teaching and foresee the need for technology integration in order to better prepare for the unexpected in the future.

Adult obesity has been associated with depression, especially in women. Whether depression leads to obesity or obesity causes depression is unclear. Chronic inflammation is observed in obesity and depression. In 63 obese women without additional diseases depression level was assessed with the Beck's questionnaire. After evaluation of depression level study group was divided into groups according to the mood status (A—without depression, B—mild depression, and C—severe depression), and serum concentration of TNF-α, sTNFs, leptin, and IL-6 were measured by ELISA. No differences in age, body mass, BMI, and body composition were observed in study groups. We did not observe differences of serum concentrations of TNF-α, sTNFRs, leptin, and IL-6 between subgroup A and subgroups B and C. It seems that circulating adipokines did not exert influence on depression levels in obese women.

Attitudes Toward Chemistry

The objective of this research was to investigate the level of students' attitudes toward Chemistry and Learning Experience (ATCLE). The research sample included 191 students (61 male and 130 female) from three universities; Universitas Negeri Mataram, Universitas Islam Negeri Mataram, and IK1P Mataram, Indonesia. The sample has been selected through cluster random sampling and snowballs random sampling. Mixed method research with a descriptive correlational survey model and a semi-structured interview was employed for the study. The data were collected by Chemistry Attitudes and Experiences Questionnaire (CAEQ) and an interview guide. Results showed no significant correlation in the level of attitude toward chemistry based on gender and grades. The finding also revealed that the attitude of pre-service chemistry teachers based on gender and grade were more positive towards research in chemistry than jobs related to chemistry. However, grades influenced the students learning experience, but there was no influence of gender on students learning experience. It is suggested that teachers need to develop a positive attitude toward chemistry and learning experiences of the students through inquiry-based learning practices.

Abstract We investigated the social relationships among adult females in two multimale-multifemale groups of black howler monkeys Alouatta pigra during a 14-month study in Palenque National Park, Mexico. Based on over 900 focal hours and over 5400 scan samples recording neighboring group members, we found that females very rarely engaged in agonistic interactions and no dominance hierarchy could be discerned. Relationships among resident females were primarily affiliative, but females of one study group spent a higher proportion of time in close proximity and engaged in affiliative interactions with one another at higher rates than females in the other study group. The strength of female relationships increased with the birth of an infant. Although no females immigrated during the study period, the temporary association of three extragroup females with our study groups implies that the social system of black howler monkeys is more dynamic than previously suggested. These findings suggest that female black howler monkeys behave more similarly to female red howler monkeys A. seniculus than to female mantled howler monkeys A. palliata.

Background: Alopecia areata is an autoimmune disorder causing patchy hair loss on scalp and other parts of the body and leading to poor self-esteem and anxiety in patients. Treatment with topical or systemic drugs like steroids or other immunosuppressants is associated with adverse effects. Hydroxychloroquine is an antimalarial drug, with T cell modulating function. This study was undertaken to assess the safety, efficacy and tolerability of Hydroxychloroquine in Alopecia areata compared to betamethasone oral mini pulse (OMP) therapy. Methods: 60 patients with alopecia areata were randomized into two groups of 30 each. Control group received tab. betamethasone 5 mg/day on two consecutive days of week for 12 weeks and Study group received tab. hydroxychloroquine 200 mg/day for 12 weeks. They were followed-up for further 12 weeks. Scale of alopecia tool, dermatology life quality index and global assessment at baseline, 12 weeks and 24 weeks were used to assess the outcome.Results: 94 patients were screened and 60 patients were included. All patients completed the study. At the end of 12 weeks, there was a statistically significant reduction in SALT and DLQI scores in both control and study groups. But at the end of 24 weeks, the study group showed an increase in the scores. Relapses were more in the study group. No significant difference in the incidence of adverse events was noted between the two groups.Conclusions: Hydroxychloroquine 200 mg/day is less efficacious in the management of alopecia areata in comparison to betamethasone oral mini pulse therapy.

AimsRecently, global-remote group studying has been made possible via digital video conferencing platforms. In preparation for the December 2020 MRCPsych part A exam, a study group was formed comprising 30 International Medical Gaduates (IMG) logging-in from different countries via 3 hour Zoom-study sessions hosted daily from 28th September until 12th December 2020 (1800-2100 GMT time). This study demonstrates the impact of online group study in preparation for the MRCPsych A exam for s via data collected through questionnaires.MethodThe data of the study were collected through the questionnaires given to the group study members containing a total of 17 questions, 5 of which were open-ended.The participants totalled 30 International Doctors who responded to an advertisement to form an online study group on Facebook. They logged-in for the sessions from seven different countries: Malaysia, India, Bangladesh, Ireland, Nigeria, Saudi Arabia, and the United Kingdom. The participants represented different working grades incuding experiences in psychiatry ranging from 0 to 5 years.Data were analysed using percentage. The answers given to the open-ended questions were each examined using descriptive interpretation methods.ResultThematic analysis demonstrated that online group study made learning faster and easier. 96.6% support using online study sessions for future exams citing that they fostered cooperation, respect for diverse opinions and motivation for regular studying. 93.1% and partly 6.9% found the experience enjoyable and enabled the cultivation of different ideas. Indeed, 89.7% relied on it as a big part of their preparation with 26 saying it contributed to their passing of the exam success.Almost three quarter of participants in the group also forged friendships and a sense of trust. It also became a platform for expressing opinions comfortably and developing communication and interpersonal skills.Different working hours and time zones represented a challenge with most linking in at odd hours. Cultural differences were ultimately accepted including aspects of delivery of information which made a few participants appear abrupt.ConclusionWith the ease in which social media connects us on a global scale, online study groups connecting IMGs from various backgrounds and diverse cultures not only makes exam preparations stimulating and easier to pass but also fosters interpersonal skills and connections that would be an asset in the long run.

e15535 Background: VEGF receptors have an important role for inhibiting adaptive immun response in colon cancer. Therefore, we analyzed VEGF receptors in circulating T cell subsets according to stage in colon cancer patients. Methods: The prospective study group consisted of 50 patients with histologically confirmed colon cancer and 30 person without any cancer history as a control group. Peripheral blood specimens were collected from the patients after the diagnosis before inducing chemotherapy and radiotherapy. Patients with active infections or autoimmune disorders, who were treated with steroids and antibiotics in the last four weeks before the study enrollment were excluded from the study group. VEGFR2 expressions in circulating T cell subsets (Th1, Th2, Th17, CTL) were analyzed by flow cyctometry. Results: Age and gender were not different between the all study groups. Mean circulating CD4+ folicullar cells were less in colon cancer patients (9.54%±3.99) than the control group (12.03%±4.34), (p < 0.01). Mean circulating CD8+ follicular cells were higher in metastatic colon cancer (n = 26) 2.48% ± 1.68, than the non-metastatic colon cancer patients (n = 24) 1.63% ± 1.37, (p = 0.02). Mean VEGFR2 expressions in Th1 cells were higher in colon cancer patients 248.8 (Mean Flourescein intensity-MFI) than the control group 224.6, (P = 0.006). Mean VEGFR2 expressions in CTL were higher in colon cancer patients (381.8) than the control group (284.7), (p < 0.001). PD-1 expressions were not different between the colon cancer patients and the control group in all circulating T cell subsets. Mean VEGFR2 expressions in Th17 cells were higher non-metastatic colon cancer patients than the metastatic colon cancer patients (326.5 and 268.4 MFI, respectively, p = 0.02). Conclusions: VEGFR2 expressions are increased in circulating Th1 and CTL subsets in colon cancer patients. Whereas PD-1 expressions were not different in circulating T cell subsets than the control. VEGFRs may play an important role for the inhibition of circulating T cell subsets in colon cancer.
