A Study of Cloze Test in TEM-4 from the Perspective of Cohesion Theory
Authors: Liu Wan , Zhang Yi
Published: March 2024

Cloze test has now become one of the core questions in various language tests. In Test for English Majors-Band 4 (TEM-4), cloze test accounts for 10% of the total score. However, cloze is also the most time-consuming and lowest-scoring test type for students. Therefore, this research aims to explore in-depth and discuss the cohesion devices that cloze tests of TEM-4 involve and strategies for coping with cloze. Results show that there are a total of 112 occurrences of cohesion devices in cloze. And the lexical cohesion device is the dominant one with 62 instances. Substitution occurs the least frequently (3 instances). In addition, specific examples are used to explain how to solve cloze questions based on cohesion theory. What’s more, it is proposed that students should comprehend solving skills based on cohesion theory and consolidate the foundation of language learning to improve the capability of coping with cloze. It is expected that English major students can benefit from this study during the TEM-4 preparation.

Background: While visual inspection with acetic acid (VIA) is an effective and affordable screening tool, the determination of the severity of cervical intraepithelial neoplasia (CIN) relies heavily on the expertise of healthcare professionals and the interpretation of colposcopic and biopsy findings. The aim of this study is to compare the frequency CIN I-III in VIA positive cases with the help of colposcopic and biopsy findings.
Methods: The prospective cross sectional descriptive study conducted among the VIA positive cases (n=100) who were attending at in colposcopic clinic of department of obstetrics and gynecology, Dhaka Bangabandhu Sheikh Mujib medical university (BSMMU) during 1st June 2010 to 30th August 2010. History includes present and past illness, personal, family history, drug history and blood pressure were done.
Results: The mean duration of married life was 16.8±10.6 years and more than a half (52.0%) of the patients’ age was 15-20 years of their first intercourse. More than one fourth (27.0%) of the patients had irregular menstrual cycle and 10.0% patients were menopause. Most (72.0%) of the study patients were multipara and the mean age of 'last confinement was 7.8±6.8 years. Majority 38(38.0%) of the patient was normal, 25 (25.0%) of the study patients had CIN I and CIN II in 13 (13.0%), CIN III in 5 (5.0%), 4 (4.0%) had invasive carcinoma and 15 (15.0%) unsatisfactory colposcopy. The colposcopic related biopsy findings was observed, 27.1% of the study patients had CIN I, 12.9% had CIN II, 12.9% invasive carcinoma, 5.9% had CIN III and 5.9% had inflammatory change.
Conclusions: CIN III in colposcopic-related biopsy findings was associated with a mixture of CIN I and CIN III in colposcopic examinations. Invasive carcinoma in biopsy results was linked to a combination of CIN III and invasive carcinoma in colposcopic findings.

Published: March 2024

Background: Managing pregnancy with post-dates is becoming a challenging issue due to increasing fetal morbidity and mortality. The study aimed to analyse the maternal and fetal outcomes of post-term pregnancies among Indian women, considering their earlier fetal maturation. Conducted over 18 months with 100 cases, the prospective observational study focused on pregnant mothers at or beyond 40 weeks gestational age, excluding those with certain medical complications.
Methods: After obtaining approval from the ethics committee and informed consent from eligible participants, detailed histories and examinations were conducted, with close monitoring until delivery and postnatal care. Inclusive criteria encompassed singleton pregnancies with cephalic presentation, while exclusions included non-cephalic presentation, congenital anomalies, and various medical complications.
Results: Revealed a predominance of primigravida women aged 20 to 35 years at 40 to 40 weeks and 6 days gestation. Spontaneous delivery occurred in 58%, with 90% delivering vaginally, while all multigravida births were vaginal post-induction. Cesarean sections were performed in 14%, primarily due to failed induction followed by fetal distress. Meconium-stained liquor was most prevalent at 42 weeks or later, correlating with higher perinatal mortality and NICU admissions in infants born beyond 42 weeks.
Conclusions: Vigilant monitoring proved crucial in averting fetal jeopardy, emphasizing the importance of timely interventions to mitigate complications associated with post-term pregnancies. This study sheds light on the unique considerations and outcomes of post-dated pregnancies in the Indian population, contributing valuable insights for maternal and neonatal care in similar settings.

Published: March 2024

Background: The present study aimed to evaluate if postpartum gestational diabetes mellitus (GDM) screening can be performed during immediate post-delivery 72 hrs instead of six weeks postpartum for follow-up.
Methods: Total 150 GDM patients were included. The sample size was calculated as 150 with Nimaster2.0 software. GDM patients are enrolled after meeting the exclusion criteria for the study. The GDM diagnosis was made by DIPSI test and treated as per guidelines. After delivery, the Dipsi test was done on PND-3 (PP1). Furthermore, all were kept on LSM irrespective of the glycaemic level DIPSI test was repeated in all Patients after 45 days (PP2).
Results: All 150 patients had a DIPSI test on 3rd day post-partum (PP1) and repeat test at 45 days (PP2)., Of these, 60 patients (40%) showed negative DIPSI test on P1 and all remained in Group 1, with 63 patients having negative DIPSI test on PP2. 50 patients (33.3%) had blood glucose between 140-199 mg (Group 2) on PP1 and increased to 53 patients in PP2 in 45 days. 40 patients had diabetic (26.6%) value (Group 3) in PP1, and out of them 34 (22.6%) remained in group 3 in PP2 after 45 days post-partum.
Conclusions: This pilot study shows that nearly 60% of the GDM patient have either IGT or diabetic value following delivery on 3rd day of PP1 and almost similar results in PP2. Hence, we can do the postpartum screening on the postpartum 3rd day and need not wait for 6 wks when more than 50% is lost for follow-up. This study shows among GDM 60% of them have underlying beta cell dysfunction.

Published: March 2024

Vaginal vault prolapse is about 4-6 per 1000 but it is increasing with increase in life expectancy with more number of years in menopausal age. It is not a common condition following abdominal and vaginal hysterectomy. It has a negative impact on the quality of life of women due to incontinence of urine, irregular defecation symptoms and sexual dysfunction along with psychosocial problems. This study compares the efficacy of most two successful surgeries which were done by abdominal and vaginal route for correcting post hysterectomy vault prolapse by postoperative assessment and at least 6 to 12 months follow up. This is the retrospective case series among post hysterectomy women attending the Gynae OPD in SVBP hospital associated with LLRM medical college Meerut from January 2022 to January 2023. Study population included 19 women divided into two groups; group 1 includes 8 women who underwent unilateral sacrospinous ligament fixation and group 2 includes 11 women who underwent abdominal sacrocolpopexy. In demographic and clinical features between the two groups, there is no statistically difference found in terms of mean age, mean weight, mean BMI and mean parity. Hence, both groups are comparable. The operating time is longer in ASC (85.90±40.23 minutes) group when compared to SSF group (43.43±6.9 minutes) (p value= 0.00096), blood loss reported in ASC (341.72±37.14 ml) slightly more than in SSF group (237.5±32.84 ml) (p value= 0.0001) and mean hospital stay is longer in ASC (6±5.1 days) than SSF group (3.2±0.9 days) (p value=0.0001). Other complications like postoperative pyrexia, wound infection, urinary complaints were higher in ASC group and at follow up, the mean vaginal length was longer in ASC (6.9±0.8 cm) then SSF (5.2±0.8cm) group (p value=0.0005). We concluded that as the ultimate aim of vault prolapse surgery is to improve the function and restoring anatomy and to improve the quality of life, in that respect, both abdominal sacrocolpopexy and sacrospinous ligament fixation both are effective methods and less complications are noted in SSF group. It also depends on the hands of an expert, though recovery time is faster in SSF than ASC group.
Laparoscopic shaving for colorectal endometriosis: a literature review
Authors: Moukit Mounir , Rahmoune Mohammed , Allilou Ismail , Babahabib Moulay Abdellah
Published: March 2024

Colorectal endometriosis is one of the most challenging conditions to manage. Surgical treatment is required when lesions are symptomatic, impairing bowel, urinary, sexual, and reproductive functions. Preoperative radiological examination should be extensive to determine the appropriate surgery: laparoscopic shaving, disc excision or rectal resection. We demonstrated that in the hands of experienced surgeons, shaving technique is possible in more than 95% of colorectal endometriotic nodules, with low complication rates compared to resection. Shaving and bowel resection are associated with comparable recurrence rates. As shaving is indicated whatever the size of deep lesions, surgeons should first consider rectal shaving to remove deep bowel endometriosis. Bowel resection should only be performed in case of major rectal stenosis (>80%), multiple or posterior lesions and stenotic colorectal nodules.

The research involved 42 mathematics student teacher of the Teacher Professional Education (PPG) program at the Department of Mathematics Education year 2015 and year 2016. The students had one year teaching experience. The workshops were carried out in 10 weeks, 6 cycles, using the design OXO, and focused on developing student abilities in planning educative learning-and-teaching (subject specific pedagogy)—which covers the following program: deepening subject matter knowledge, the development of learning methods and materials, the development of learning media and assessment tools, the development of teaching plans and syllabi, and the implementation of these components in the real classrooms. The strategy, used in the workshops, was a cyclic model: plan-action-reflection (PAR), which is adapted from the lesson study principles: plan-do-see. This strategy was implemented in a cycle of process, product, and open lesson. The instrument included professional and pedagogical competencies test—which covers school mathematics topics grades 7-12. The results showed that SSP workshops with cyclic model, applying the lesson study principles, are effective for developing student professional and pedagogical competencies—in medium level; most of students felt comfortable and were facilitated during the workshops; and the minimum competencies, quantitatively, can be achieved with the improvement is in the medium level.

Published: March 2024

This study examines the impact of implementing multiple representation method in responding to the challenge of learning science specifically in relation to enhancing students’ reasoning skill. Pre-experimental method was applied to obtain research data from participants consisted of 8th grader students at a private junior high school in Bandung, Indonesia. The effect on reasoning skill was studied from students’ arguments in answering question related to respiratory system. The arguments were then analyzed by the completeness of argument component, level of argument, and quality of argument referring to Toulmin’s argumentation pattern (TAP). The findings show that students experienced significant improvement in reasoning skill expressed in their arguments. The improvement was evident in the higher argument level and better argument quality achieved by students after the implementation of multiple representation method. In relation to quality of argument, the overall quality of argument shifted from the domination of weak arguments to the domination of strong arguments. Additionally, the use of multiple representation in learning assists students to be able to use various forms of information such as graphics, visual images, tables, scientific formula, and written expression in explaining concepts.

Published: March 2024

Penelitian ini bertujuan mengembangkan strategi pembelajaran matematika dengan pendekatan realistik di SLTP Negeri 1 Lembang, pada pokok bahasan Garis-garis yang sejajar. Selain dari pada itu penelitian ini menggali informasi apakah pembelajaran realistik membantu siswa memahami matematika secara bermakna. Dalam menerapkan pendekatan ini digunakan paradigma penelitian “Developmental Research” bermula dari proses desain, development dan evaluasi pelaksanaan proses desain ini. Dilaksanakan sejak Juni 2001 sampai dengan Nopember 2001. Analisis terhadap hasil penelitian ini difokuskan kepada pengembangan strategi guru mengajar, dan juga strategi siswa memberikan jawaban. Adapun tentang minat, sikap, serta tanggapan para siswa terhadap pembelajaran matematika dengan menggunakan pendekatan realistik merupakan informasi tambahan untuk mendukung strategi yang dikembangkan oleh guru secara empirik dan strategi pembelajaran secara teoritik.Hasil penelitian menunjukkan bahwa dalam mengimplementasikan pembelajaran matematika dengan pendekatan ini, guru sebagian menggunakan strategi yang ditulis secara teoritik, namun sebagian waktu lagi belum bisa menerapkan sehubungan masih melekat kebiasaan pembelajaran sehari-hari yang masih menggunakan pendekatan bersifat mekanistik. Untuk dapat mengimplemen-tasikan pembelajaran matematika dengan pendekatan realistik, perlu pemahaman lebih lanjut filosofi pembelajaran realistik, dan implementasi secara berkesinambungan untuk topik-topik lain dalam matematika.

Berdasarkan hasil observasi dan wawancara pada beberapa guru fisika di salah satu SMAN di kota Bandung, diperoleh bahwa selama ini proses pembelajaran di sekolah masih bersifat “teacher centered” serta sebagian besar siswa masih bersikap pasif selama proses pembelajaran dan masih kurangnya keberanian siswa dalam bertanya. Dalam pembelajaran IPA khususnya fisika, erat kaitannya dengan menyajikan permasalahan dalam kehidupan sehari-hari yang berkaitan dengan konsep yang akan dipelajari yang menuntut siswa untuk belajar berpikir dan mengembangkan keterampilan berpikirnya sehingga dapat memecahkan suatu permasalahan. Adapun tujuan dari penelitian ini adalah: 1) Mengetahui peningkatan kecakapan berpikir rasional siswa dalam pembelajaran fisika di SMA dengan diterapkannya model pembelajaran pemecahan masalah, 2) Mengetahui efektifitas model pembelajaran pemecahan masalah terhadap peningkatan kecakapan berpikir rasional siswa dalam pembelajaran fisika di SMA, 3) Mengetahui respons siswa terhadap pembelajaran fisika dengan menggunakan model pembelajaran pemecahan masalah. Metode yang digunakan dalam penelitian ini adalah metode eksperimen semu (quasi eksperiment) dengan desain penelitian Randomized Control Group Pretes-Postes Design. Sampel penelitian diambil sebanyak dua kelas, sebagai kelas kontrol dan kelas eksperimen dari enam kelas XI IPA pada salah satu SMAN di Bandung, dengan masing-masing kelas berjumlah 37 orang siswa (kelas eksperimen) dan 39 orang siswa (kelas kontrol). Instrumen penelitian yang digunakan adalah: 1) tes kecakapan berpikir rasional, 2) format observasi guru dan 3) angket respons siswa. Setelah dilakukan penelitian, ditemukan bahwa peningkatan kecakapan berpikir rasional siswa pada kelas eksperimen lebih tinggi dibandingkan dengan kelas kontrol.

Published: March 2024

GaN merupakan material semikonduktor yang memiliki nilai celah pita energi (Eg ) sekitar 3,45 eV pada temperatur ruang dengan struktur transisi langsung. Keadaan ini membuat GaN sangat potensial untuk aplikasi divais optoelektronik yang beroperasi para rentang panjang gelombang UV. Dalam studi ini telah dilakukan uji penumbuhan lapisan (GaN) di atas  substrat Si (100) dan Al2O3 (0001) dengan teknik  sol-gel spin-coating dengan menggunakan kristal gallium-citrate-amine sebagai prekursor Ga. Teknik ini tergolong sederhana, mudah pengoperasiannya dan relative murah. Hasil karakterisasi lapisan GaN yang berhasil ditumbuhkan menunjukkan bahwa baik yang ditumbuhkan di atas substrat  Si (100) maupun  Al2O3 (0001) masih memiliki struktur polikristal.  Kualitas morfologi lapisan GaN masih relatif rendah, dengan ketebalan rata-rata berkisar antara 1-1,5 m. Nilai celah pita energi lapisan GaN yang ditumbuhkan di atas Al2O3 (0001) berdasarkan hasil karakterisasi UV-Vis spectroscopy adalah sekitar 3.20 eV. Nilai ini masih sedikit lebih rendah dari nilai idealnya.
