Identification of essential integrated STEM curriculum implementation components
Authors: Clark Dr. Quintana (Quincy) , Capobianco Dr. Brenda M. , Esters Dr. Levon T.
Published: October 2023

Measuring the factors affecting the implementation process are critical steps for understanding how, why, and under what circumstances integrated STEM curriculum innovations work. The overarching goal of this National Science Foundation (NSF) funded project was to design, field-test, implement, and evaluate contextualized integrated STEM learning experiences that use agricultural life sciences (AgS) as a context. To that end, we developed AgS model-eliciting activities (MEAs). MEAs are thought-revealing tasks that require student teams to mathematize real-world situations. The present study employed the iterative engineering design process guided by the innovation implementation framework to identify essential structural and interactional integrated STEM curriculum implementation components. Common Core State Standards (CCSS), teacher scopes and sequence plans, student readability level, agricultural life science contexts, culturally relevant pedagogy, and access to STEM mentors were mapped to the AgS MEA curriculum implementations. Drawing on semi-structured teacher interviews (individual and focus group), recorded teacher development sessions, and documented expert consultations, this study provides research-to-practice findings that support the effective implementation of an innovative integrated STEM curriculum for elementary grade levels. An iterative engineering design process guided by the innovation implementation framework provided a strategic iterative method to utilize teacher feedback over five AgS MEA implementations. Six structural and six interactive AgS MEA implementation components were identified. The results from this work can help mitigate the barriers researchers and teachers experience when implementing integrated STEM curriculum innovations.
Preparing pre-service agricultural education teachers to teach agricultural mechanics: Are we doing enough?
Authors: Trickett Lexi , Byrd Alex Preston , Anderson Ryan G. , Haynes J. Chris
Published: October 2023

Agricultural mechanics is a technical skill area that poses numerous challenges for teacher preparation programs due to safety, time needed to learn technical skills, and credit hour requirements. The skills required to manage a laboratory are crucial for instructors of agricultural mechanics curriculum. Agricultural mechanics is a popular course in secondary schools, but studies found that pre-service teachers were ill-equipped to teach the courses effectively. Determining the level of readiness of graduates of teacher preparation programs to teach agricultural mechanics was the purpose of this study. Certifying institutions for agricultural education teachers across the nation comprised our target population. A questionnaire was used to collect data for this study, resulting in 48% response rate (n = 52). Of the nine agricultural mechanics curriculum content areas most teachers reported they had five in their state curriculum. The nine content areas were determined to be “Important” by the teachers in this study. Hand/Power Tools (M = 3.69) was the only content area that institutions ranked their graduates as “Prepared” to teach. The remaining content areas were ranked as “Somewhat” or “Poorly” prepared. Most institutions stated that they required at least one course in agricultural mechanics in their program, with the average requirement being five to eight hours. It can be concluded that agricultural mechanics course requirements have decreased since 2005, even though the content is heavily taught at the secondary level. This study has shown that we must re-evaluate how we prepare students to be competent to teach agricultural mechanics.

The study investigated the health seeking behaviours of pregnant women of different parities in Enugu East local government area, Enugu State, Nigeria. Three research questions were stated and three null hypotheses were equally formulated to guide the study. The descriptive survey research design was adopted for this study. The population for the study was 1,660 registered pregnant women attending antenatal clinic in the 20 primary health centres. The sample size for this study was 166 respondents who were selected through the proportionate stratified random sampling technique. The instrument for data collection was researchers-developed structured questionnaire which was validated by three experts. The instrument comprised 23 items divided in clusters based on the three research questions. Reliability of the instrument was determined using Cronbach Alpha statistic which yielded .81, .79 and .80 for clusters 1, 2 and 3 respectively. The instrument had an overall reliability index of .80 which indicated that the instrument was reliable. Data collected were coded into the Statistical Package for Social Sciences (SPSS) software package version 23.0, which was used in processing all the relevant data. The research questions were answered descriptively using mean scores and standard deviation, while the hypotheses were tested using Analysis of Variance (ANOVA) at .05 level of significance. Findings of the study showed impressive health seeking behaviour among the sampled pregnant women in terms of attending antenatal visits, dedicating themselves in the practice of personal hygiene, as well as indulging in moderate exercises. Based on the findings of the study, the study recommended among others, the need for intensified health sensitization to be organized regularly for women of reproductive ages, in order to sustain their awareness and consciousness about the importance of antenatal visit.

Doğal dilleri anlayabilen bir sistemin temel özellikleri neler olmalıdır? Hangi engellerin aşılması gerekmektedir? Doğal dil anlama süreçleriyle ilgili önemli sorunlardan birisi de muğlaklık olarak görülmektedir. Muğlaklığın iki türünden bahsedilebilir: Sözdizimsel muğlaklık ve sözcüksel muğlaklık. Sözdizimsel muğlaklık durumunda verilen bir ifade bağlama göre birden fazla şekilde sözdizimsel parçalarına ayrılabilmektedir. Muğlaklığın diğer bir türü ise sözcüksel muğlaklıktır. Bu durumda, kelimeler birden fazla anlama sahiptirler. Sözcüksel muğlaklık doğal dilleri biçimsel dillerden ayıran özelliklerden birisidir. Bir programlama dilinin söz dağarcığındaki ifadeler için muğlaklıktan bahsetmek mümkün değildir. Sözcüksel muğlaklık doğal dillerin modellenmesinin önünde bir engel midir? Diğer bir deyişle doğal dillerdeki anlamsal muğlaklığın yapay zekâ çalışmalarını kötü yönde etkilediği söylenebilir mi? Bu çalışmada güncel literatür referans alınarak sözcüksel muğlaklığın özellikle de çokanlamlılığın doğal diller için bilişsel açıdan aslında bir avantaj olduğu ifade edilmektedir.
A Secure Communication System of Synchronized Chua’s Circuits in LC Parallel Coupling
Authors: V Satya Prakash , S Narender Reddy , A Sadanandachary
Published: October 2023

Synchronization capability of two identical chaotic systems can be used for constructing the secure communication systems where the chaotic signal is used as the information carrier. In this paper, a secure communication system is designed by using the bi-directionally synchronized identical Chua’s circuits in LC parallel coupling. LC parallel circuit is used as the new coupling element instead of using a single resistor or capacitor or inductor as the coupling element. This makes the complete synchronization of Chua’s circuits possible for many different sets of coupling inductance and capacitance values so that the flexibility of constructing the secure communication systems is realized. Both the synchronized Chua’s circuits in LC parallel coupling and the corresponding secure communication system are constructed by using the LTspice software. The simulation results show that the secure communication system proposed in the present paper is very efficient for the message transmission for different pairs of coupling inductance and coupling capacitance values where the complete synchronization of Chua’s circuits is observed occur. The two essential properties of an ideal secure communication system - perfect message masking and recovery are observed when compared to other secure communication systems already proposed and constructed previously. So, the simulation results of the present study can be used for practically constructing the efficient communication systems in future.
Challenges in the Diagnosis of Extranodal Non-Hodgkin’s Lymphoma

Authors: Prabawa Dika Wisnu , Rena Renny A
Published: October 2023

Introduction: Primary non-Hodgkin’s lymphomas (NHLs) of the oral cavity, especially in the tongue, are extremely rare and account for 1% of all malignant tumors of the oral cavity, accounting for 7% of all primary Waldeyer’s ring NHLs. Clinical features are non-specific ulcerative lesions that do not heal, making its diagnosis challenging. Fine-needle aspiration biopsy was helpful in the early diagnosis of the intraoral NHL involving a cervical lymph node. Case Report: we present a rare case of extranodal NHL of the base of tongue in a 55-year-old female who presented with a mass in the base of the tongue with cervical lymphadenopathy. The diagnosis was confirmed as primary NHL diffuse large B cell type by histopathological and immunohistochemistry results. Conclusion: A careful clinical evaluation supported by histopathological and radiologic investigations will help identify the disease early, resulting in a better prognosis.

Authors: Rochmah Nur , Faizi Muhammad , Hisbiyah Yuni , Perwitasari Rayi Kurnia , ‘Aina Qorri , Ni’mah Nur Lailatun
Published: October 2023

Background: Menarche is a crucial indicator of a female’s sexual development because of the interaction of the hypothalamus-pituitary-ovarian axis with the reproductive and endocrine systems. The timing of menarche appears to have shifted to younger ages over the past century. A risk factor for early menarche is a lifestyle change, notably the frequency with which fatty meals and junk food are consumed. This study aimed to determine the mean age at menarche in Indonesian adolescents, especially boarding school students in Surabaya. Method: This cross-sectional research included Alif Laam Miim Islamic Boarding School students in Surabaya. The students’ menarche ages were obtained via direct interviews, and their height and weight were assessed using conventional anthropometry. SPSS was used to do the statistical analysis. Mean, standard deviation, frequency, and percentage were used to represent descriptive data. Results: This study included 45 girls with a mean age of 13.72 + 0.72 years old. The mean age of menarche was 11.45 + 0.99, and 3 (6.66%) of our subjects had not had menstruation yet. One student (2.22%) experienced menarche at the age of 9. We found no statistically significant correlation between the mean age of menarche with nutritional status (p = 0.308; r= -0.155). Conclusions: Our study taken on Boarding school students found that the mean age of menarche was 10.66 + 3.03 and it was relatively younger than other studies taken in Indonesia.

Published: October 2023

Background: Spontaneous intracerebral hemorrhage accounts for 10-15% of cerebrovascular events. Various modalities of patient management, both conservatively and surgical. Despite its deadly nature and extensive studies, there is no standard model for predictive factors in intracerebral hemorrhage-related mortality. Methods: A retrospective cohort analysis on patients with supratentorial spontaneous intracerebral hemorrhage who received surgical treatment for clot evacuation. Factors including age, sex, initial Glasgow Coma Scale score, the volume of the clot, existing intraventricular hemorrhage, existing subarachnoid hemorrhage, signs of cerebral herniation from head CT-Scan, duration of the surgery, and surgical technique were analyzed. Results: Data for 44 patients were included in this study. The mean age was 54.68 ±12.79 years old, with 64.6% of the sample being males. The mean GCS score of the sample is 9.3 ± 3.15. Subarachnoid hemorrhage was noticed in 34.1% of cases. Intraventricular hemorrhage extension was found in 27.3% of cases. Cerebral herniation on CT-scan was noticed in 50% of cases. Based on surgical characteristics, the mean surgical time is 194.84 ± 54.84 mins. Almost two-thirds of the cases performed craniectomy procedure 28 (63.6%). We found that subarachnoid hemorrhage (OR 5.77 [1.12 – 29.7]; p = 0.036) and cerebral herniation (OR 8.26 [1.91- 35.7]; p = 0.005) were considered as significant factors in predicting 14-day mortality after multivariate analysis. Conclusions: Subarachnoid hemorrhage and cerebral herniation are good predictors of 14-day mortality in patients with sICH who are surgically treated. Earlier and shorter duration of the surgery showed no correlation to the outcome.

This study conducts a comprehensive financial assessment of Greece's ten largest energy companies during the tumultuous period of 2019 to 2022, amidst the unprecedented challenges posed by the COVID-19 pandemic. Employing a meticulous analysis of crucial profitability ratios, I delve into the financial resilience and adaptability of these firms within the ever-evolving energy sector landscape. My findings reveal a diverse spectrum of financial performances during the early pandemic years (2019-2020), with notable discrepancies in net profit margins. As the world transitioned to the post-pandemic era (2021-2022), I witnessed varying degrees of adaptability, with certain companies demonstrating impressive resilience while others grappled with shifting market dynamics. This research underscores the imperative of tailored financial strategies and adept cost management practices within the energy sector to effectively weather the challenges of an uncertain world. The insights gleaned offer valuable guidance to industry stakeholders and decision-makers in navigating the complex terrain of Greece's energy landscape.

Human-Centred Design Approach for Revisioning Public Transportation System in Malaysia
Authors: Kuys Jo , Day Kirsten
Published: October 2023

Improving urban transportation systems requires an emphasis on users’ end-to-end journey experience, from the moment the user steps out of their home to when they arrive at their destination. In considering such end-to-end experiences, Human Centred Design (HCD) must be integrated from the very beginning to generate viable urban planning for the public. An HCD approach will encourage innovative outcomes while acknowledging all factors that need to be understood along the journey. We provide evidence through field research analysis to show that when designing and planning for well-integrated public transportation in an urban setting, it is not just about the physical manifestation of a particular outcome; moreover, it is about the context and human behaviours that need to be considered throughout the design process. Humans and their behavioural factors are vitally important to implement sustainable public transport systems for future urban infrastructure successfully. Through an in-depth literature review of HCD approaches for urban transportation systems, we provide a base to exploit the benefits and highlight the importance of including HCD in public transportation projects for greater patronage, resulting in more sustainable cities. This paper will provide a much-needed rationale behind the HCD approach in all public transportation projects to understand different levels of user experience, from the setting of transport policy to the implementation of urban infrastructure, vehicle and interface design.

OBJECTIVE: To determine diagnostic accuracy of contrast enhanced T2 FLAIR in diagnosing infective meningitis considering CSF analysis as gold standard.

METHODS: A prospective study of 101 patients with clinical suspicion of meningitis, referred to the radiology department of Mayo Hospital Lahore for MRI examination was done. Patients with reduced renal function, claustrophobia and metallic implants were excluded from the study. The MRI brain with contrast including postcontrast T1WI and FLAIR sequences was performed at 1.5 T machine. The images then evaluated by the competent experienced radiologists. Cerebrospinal fluid (CSF) analysis of the patients was done through lumbar puncture and was considered the “gold standard” against which comparison of MRI findings was done.  Data analysis was done by using SPSS 23.

RESULTS: Sensitivity and specificity of contrast enhanced T2 FLAIR MRI in detecting infective meningitis was 95.08% (CI-95%: 86.51-98.31) and 82.5% (CI-95%: 68.05, 91.25). While positive predictive value and negative predictive value was 89.23% (CI-95%: 79.4, 94.68) and 91.67% (CI-95%: 78.17, 97.13) respectively. Diagnostic accuracy was 90.1% respectively.

CONCLUSION: Results of this study showed higher sensitivity and specificity for contrast enhanced T2 FLAIR in diagnosing infective meningitis. So use of contrast enhanced T2 FLAIR can be helpful in early screening and diagnosis of meningeal infections.

Background: The relationship between iron deficiency and certain phenomenon like hematological alterations, inadequate growth, altered thermoregulatory function and reduced cognitive function have been well known.

Objectives: To determine the frequency of iron deficiency in children with hypochromic and microcytic anemia on blood smears.

Methods: This case-control study was performed in the department of pediatrics, Sahiwal Teaching Hospital, Sahiwal, Pakistan from May 2022 to April 2023. For cases, we included 179 children of both genders aged between 1 month and 15 years with hypochromia and microcytosis. Similar number of healthy children (n=179) of both gender and aged below 15 years were enrolled as controls. At the time of enrollment, socio-demographic information like gender, age and residential area were recorded. Local institutional laboratory was utilized for the hematological parameters. Hypochromia and microcytosis were labeled as MCV< 76fl and MCHC < 30 g/dl of red cells while blood film also depicted hypochromia and microcytosis. IDA was termed as serum ferritin < 12 ng/dl.

Results In a total of 358 children, there were 192 (53.6%) boys. The mean age was 7.8±3.2 years while 184 (51.4%) children were between 6-15 years. Residential status of 196 (54.7%) children was rural. Overall, iron deficiency was diagnosed in 209 (58.4%) children. Among cases, 171 (95.5%) children had iron deficiency while among controls, 38 (21.2%) children had IDA (p<0.0001). Cases and controls were compared for various hematological laboratory parameters and statistically significant differences were observed for all parameters among cases and controls (p<0.0001).

Conclusion: The frequency of iron deficiency was 95.5% among children with hypochromia and microcytosis on blood smears. Hematological parameters were significantly deranged among children with hypochromia and microcytosis when compared to healthy children.

Introduction: Gastric carcinoma is the second leading cause of cancer related deaths in the world.  Aim of the present study was to determine the association of HER2 overexpression with prognostic factors in gastric adenocarcinoma affected Pakistani patients.

Methods: For this purpose, immunohistochemical staining of gastric cancer patients (n=200) was performed. HER2 was found to be overexpressed in 70% of cases included in the study. Association of HER2 expression with age greater than 40 years at the time of diagnosis, histological types and moderately differentiated grades of primary gastric adenocarcinoma was observed.

Results: HER2 was found to be overexpressed in 20% of cases. No association of HER2 was identified with the gender of the patients. Interestingly, HER2, overexpression was present in 75% of intestinal and 37% of diffuse type gastric adenocarcinoma. Based on tumor differentiation, well-differentiated (grade I) and moderately differentiated type (grade II) adenocarcinoma showed overexpression of HER2 in 90 and 80% patients respectively. Moreover, 60% patients having poorly differentiated adenocarcinoma (grade III) also exhibited HER2 overexpression.

Conclusion: Due to presence of HER2 overexpression in diffuse type gastric carcinoma as well, it is suggested that every case of gastric adenocarcinoma should be tested for HER2 overexpression so that they can be offered targeted molecular therapy for better survival.
Sustainable Development Goals and the role of and implications for primary care physicians
Authors: Renganathan Elil , Davies Philip
Published: October 2023

The Declaration of Alma-Ata in 1978 and the subsequent Declaration of Astana in 2018 highlight the important role of primary health care in delivering ‘health for all’ and supporting progress towards universal health coverage. Alongside these key declarations, the United Nations’ Sustainable Development Goals (SDGs) establish an ambitious framework aimed at promoting sustainable development worldwide by addressing poverty, inequality, climate change, health and other global challenges by 2030. There has been progress in respect of many SDGs since their launch in 2015. Nevertheless, many challenges remain, and there will need to be a significant increase in effort if the 2030 targets are to be met in full. Primary health care in Malaysia has evolved in line with broader, global developments. Nonetheless, there are opportunities for the country’s primary care physicians to do more to support efforts to achieve the SDGs, including those that extend beyond the health sector as conventionally defined. This paper outlines a number of areas where primary care physicians, fulfilling roles as clinicians, community members, managers of their practices and influential members of society, can contribute to promoting sustainable development in line with the SDG agenda.

Introduction: Malaysia is one of the hardest-hit countries by COVID-19 in Asia. The rapidly rising number of cases had sparked fear among healthcare providers. This study aimed to assess the determinants of fear towards COVID-19 among healthcare providers in primary care settings.
Methods: This online-based cross-sectional study was conducted among 1280 healthcare providers aged ≥18 years from 30 primary care clinics in the state of Selangor, Malaysia. The Fear of COVID-19 Scale was used to assess the level of fear, and the results were analysed using multiple linear regression.
Results: The mean age of the respondents was 36 years, and the mean working experience was 11 years. The majority of the respondents were women (82.4%) and Malays (82.3%). The factors that were significantly correlated with higher levels of fear were underlying chronic disease (ß=1.12, P=0.002, 95% confidence interval [CI]=0.08, 3.15), concern about mortality from COVID-19 (ß=3.3, P<0.001, 95% CI=0.19, 7.22), higher risk of exposure (ß=0.8, P<0.001, 95% CI=0.14, 5.91), concern for self at work (ß=2.8, P=0.002, 95% CI=0.08, 3.10) and work as a nurse (ß=3.6, P<0.001, 95% CI=0.30, 7.52), medical laboratory worker (ß=3.0, P<0.001, 95% CI=0.12, 4.27) and healthcare assistant (ß=3.9, P<0.001, 95% CI=0.17, 5.73). The level of fear was inversely correlated with a higher work-related stress management score (ß=−0.9, P<0.001, 95% CI=−0.14, −5.07) and a higher sleep quality score (ß=−1.8, P<0.001, 95% CI=−0.28, −10.41).
Conclusion: Family physicians should be vigilant and identify healthcare providers at risk of developing COVID-19-related fear to initiate early mental health intervention.

Hyperthyroidism is commonly seen in primary care settings. However, the management of hyperthyroidism might be unclear to primary care doctors. Various guidelines have been published to assist clinicians in the management of thyroid disorders at various levels of care. The extensive coverage of these guidelines may not appeal to busy clinicians, and the guidelines do not focus on often resource-limited primary care settings. In this article, we aim to describe a practical guide for managing hyperthyroidism in primary care settings using an ABC approach.
