The aim of this study was to explore the needs for the identification ofdesign elements of a web-based learning system that would help students develop their science process skills (SPS) to be used in science lessons. A descriptive survey method was adopted as the methodology of the study. Survey data was collected from a sample of 36 teachers and 196 middle school students (grades 5 to 8). The results of the study indicated that students had difficulty in learning science subjects. They thought that they could learn the subjects in the science course better with technological and educational support, and various teaching activities. Teachers stated that the web-based education system should meet the following requirements be simple and understandable, be relevant to real/everyday life, be an interactive system, which is rich in content and images, and include various multimedia elements such as simulations, animations, and 3D materials. On the other hand, many students stated that a web-based learning system that will help them learn the subjects in the science course should have course videos (educational videos), test/solved/sample questions, practice exams, accurate and reliable information. In addition, the students stated that this web-based learning system should be simple and understandable, have easy and rich content, be interactive and have a good technical infrastructure. Both teachers and students thought that “observing”, and “experimenting” skills would be improved the most in technology-enhanced learning environments. In addition, teachers stated that the benefits of developing students’ science process skills in real life would be “gaining a scientific perspective on events”, “awareness of the problem(s) around them”, “science literacy”, “enabling the student to access the information himself/herself”, “expanding perspectives on events”, and “able to solve the problems they encounter more easily”.

The sample of this causal-comparative study comprised 6,039 students selected from secondary schools in Isparta who took the LGS in 2020. The data were obtained from the Isparta Directorate of National Education on a chart demonstrating the participants’ demographic characteristics and the percentiles of their exam scores. The findings revealed significant differences between the students starting school at 60-65, 66-68, and 69-71 months and those with a school starting age of 72 months and older by exam achievement. In this sense, the students starting school at an early age (60-71 months) had poorer achievement in the LGS than their counterparts starting school at an older age (72 months and above). Moreover, the students’ achievement on the said exam significantly differed by gender. Accordingly, the female students demonstrated greater achievement in the LGS when compared to the male students. Considering the findings, it may confidently be asserted that it would be appropriate to amend the provision of the relevant regulation as the minimum age for starting school to be 72 months as of the fall semester.

Wound healing is promoted by a series of growth factors, secreted from the alpha granules of the platelets. Platelet rich
plasma (PRP) emerged as a clinical strategy to increase the physiologic concentration of platelets and its clinical use
for a large spectrum of disorders is reported, with good results. Extensive burns represent a promising field for PRP use,
those patients confronting challenging wound healing and poor long-term results. We present our initial clinical
experience represented by a case of a 51-year-old male patient, severely burned, who benefited from sequential
surgical treatment of deep burn wound excisions and coverage using autologous and allogenic skin grafts. PRP was
added to this patient’s therapy in two stages, being injected and externally applied on the autografts in functional areas
of the hands and the right upper arm region where both autografts and allografts were placed, with the exciting result of
promoting allograft integration, long-term persistence and healing. Several literature data validate successful clinical
applications of PRP in various therapies, including treatment of soft tissue injuries and chronic wounds, orthopedic
surgery, burns, maxillo-facial surgery and elaboration of tissue-engineered products. Based on our preliminary
experience and favourable reports in the literature, we encourage wider use of platelet rich plasma for
immunomodulation and tissue-engineered constructs, due to its effects on local inflammatory response and role in
enhancing the integration of various types of tissue grafts.

teamwork as a significant performance of a successful operation expansion grows with the spreading of their business
in the international environment and the strengthening of competition. The paper’s subject matter is research on the
attitudes of the owners and higher-level managers of different Serbian textile organizations whose focus is on the
valorisation of the performance of teamwork in an organization. The research intends to assess the defined
characteristics interacting with teamwork as a crucial concept of human resource management that has to be consistent
and explicit, frequently also being the decisive organizational success factor. The paper starts from the premise that
member selection is the most significant for the success of a team striving to rotate the leadership structure to make the
members do key organizational tasks. All the more so because those making relevant decisions and the leadership style
differ depending on the business operations level, the length of business operations and the special attributes of each
organization. The results obtained in this research study show that the business operations level and the length of
business operations significantly influence differences in organizational teamwork rates as observed through a collective
influence of the defined variables. In the given study, comparative statistics methods, hypothetical-deductive methods,
analytical-deductive and comparison methods, historical and statistical-descriptive methods are used.

Published: September 2023

In this research, cotton fabrics were treated with carboxylated chitosan, loaded by the pad-dry-cure method for
investigating the absorption of heavy metals and the Ultraviolet (UV) protection properties of fabric samples. For this
purpose, chitosan-treated cotton fabrics were soaked in CuSO4 solution to investigate the rate of heavy metal
absorption. The surface morphology of cotton fabrics was investigated using Scanning electron microscopy (SEM)
analysis. Inductively coupled Plasma Spectroscopy (ICP) analysis was employed to examine the amount of heavy
metals' absorption upon chitosan-treated cotton fabrics. Besides, reflection and transmission spectrophotometry
analyses were used to examine the optical properties of cotton fabrics. The results show a noticeable increase in copper
absorption by increasing the amount of chitosan. The maximum absorption of Cu belongs to the %6 chitosan-treated
sample by 7357.6 PPM, equal to %7.35. The more concentration of chitosan in the fibre causes a higher rate of UV
protection. Therefore, the chitosan-treated cotton fabrics examined in this work can be used for various water filtration
purposes, notably to eliminate toxic metals. Also, It can be used as a wearable textile for protecting against harmful UV
rays.

Published: September 2023

Environmental regulation is an important tool to reduce CO2 emissions. To investigate the relationship between
heterogeneous environmental regulations and CO2 emissions of China's textile industry (CTI), this paper uses the
threshold model and panel model to study the impacts of command-based, market-based and public-based
environmental regulations (CER, MER and PER) on the total carbon emissions and carbon emission intensity of CTI
from 2004 to 2019. Then it further explores their regional heterogeneity. The results show that: at the national level, CER
has a forced emission reduction effect and a green paradox effect on CTI’s total carbon emissions and carbon emission
intensity, respectively. And MER shows a forced emission reduction effect on carbon emission intensity. But the
coefficients of PER are not significant. At the regional level, the result verifies a U-shaped relationship between CER
and CO2 emissions in the eastern textile industry. And CER shows a forced emission reduction effect in the central and
western regions. The impact of MER on the carbon emission intensity of the eastern textile industry is N-shaped, which
means MER can lower carbon emission intensity only within a certain range. And its impacts on the central and western
regions are also the forced emission reduction effect. There is an inverted U-shaped relationship between PER and the
total carbon emission in the eastern textile industry. While PER has always had a green paradox effect on carbon
emission intensity in the eastern region. Other coefficients are not significant. Finally, this paper puts forward the policy
suggestions to mitigate the CO2 emissions of CTI.

To investigate how the electrical properties of AlGaN/GaN HEMTs are dominated by the near-surface region, transmission line method and X-ray photoelectron spectroscopy (XPS) measurements were conducted on three samples. There was one sample with poor ohmic properties. The XPS results indicate that the surface-Fermi-level, E
FS, position of the poor-ohmic sample was deeper than the others. When a 5 nm thick surface layer was removed by contactless photo-electrochemical etching, E
FS shifted to the same position as the others and the contact resistance improved. These results indicate that the control of the near-surface region of AlGaN can be a dominant factor changing the E
FS position, which greatly affects the ohmic properties.

EFFECTS OF TRAFFIC-RELATED AIR POLLUTION ON COGNITIVE FUNCTION AND ENVIRONMENTAL AWARENESS OF ADOLESCENTS
Authors: Neogi Susmita
Published: September 2023

Air pollution has become a global public health concern. Common sources of outdoor air pollution are
combustion of fossil fuels, and industrial and agricultural processes. For the last decade, literature on the
detrimental impacts of air pollution on brain, cognition and behavior has increased immensely. There is increasing evidence of
the hazards of air pollution on the central nervous system (CNS). Furthermore, air pollution has recently been considered as a
suspected neurodevelopmental toxicant. There is enough evidence that exposure to a range of largely trafc-related pollutants
is associated with quantiable impairment of brain development in the young and cognitive decline in the elderly. Since there
is insufcient evidence in case of adolescents, the present study has been undertaken to explore the adverse effects of trafc
related air pollution on cognitive functioning and environmental awareness of adolescents belonging to the age group of 16 to
18 years. Samples have been selected from two higher secondary schools and the school selection has been done purposively
on the basis of proximity of the school from the main road with heavy amount of trafc throughout the day. Four standardized
tests on cognitive functioning and an Environmental awareness questionnaire have been administered and data have been
analyzed by descriptive statistics, t-tests and one-way analysis of variance. The ndings are coherent with earlier studies
suggesting signicant adverse inuence of air pollution on cognitive functions as well as environmental awareness. Further

THE STUDY OF METOPISM IN HUMAN ADULT SKULLS IN WESTERN MAHARASHTRA REGION
Authors: Margam Sarita , Malvankar Megha
Published: September 2023

The human forehead is formed by means of a singular, unpaired, median, and symmetrical bone called
the Frontal bone. In process of development, this bone is formed in two symmetrical halves, being
separated by a suture. This suture is called Metopic suture. The extent of metopic suture is from the anterior angle of the bregma
to the nasion. After birth the two halves of the frontal bone are united to form a single, symmetrical median bone by
obliteration/closing of the metopic suture. Normal physiological closing time of metopic suture is controversial, normally closed
at birth while some does not fuse until the second year of the age. Persistence of metopic suture in adulthood is called as
Metopism. The observation and knowledge of metopic suture is important for paleodemography, forensic medicine, radiologist
and neurologist. In the present study, the objectives were to determine the incidence of metopism in human adult skulls of
Maharashtra region.

31 year old female with cholelithiasis with common bile duct stone with no associated comorbidity
presented to surgery clinic. She underwent ERCP for removal of common bile duct stone and placement
of biliary stent.Intraoperatively her vitals were stable and after the procedure she was shifted to postoperative care unit.
Though her haemodynamics remained stable, she was never “fully awake”, though responding and nodding to commands.
After about 20 minutes in recovery room she developed bradycardia with heart rate 30 beats/minute and hypotension. Assisted
ventilation was started with 100% oxygen using bains circuit and inj atropine 1 mg iv was given and noradrenaline infusion was
started and titrated to effect. She responded positively within minutes and started maintaining haemodynamics and
respiration without assistance/drugs. Strangely her GCS deteriorated to E1V1M2; and she developed decerebrate rigidity and
ophisthotonus posture. She was intubated under cover of propofol (2.5mg/kg) and succinylcholine (2mg/kg). Her CT head,
thorax and abdomen was done which showed normal study. Her MRI was done which showed early hypoxic ischaemic
encephalopathy. This was surprising as these changes were caught within 4 hours of completion of procedure indicating
relatively long standing hypoxic damage to brain. She was managed conservatively. After 1 week her MRI showed hypoxic
encephalopathy involving bilateral fronto-parietal regions. Tracheostomy was done and managed conservatively and was
discharged from intensive care unit with tracheostomy tube in situ. The patient recovered gradually and was able to perform
normal daily activities over a period of one month.

Published: September 2023

We report a 59-year-old female diabetic and hypertensive who developed AGEP, 24 hours after
commencing antibiotics for urinary tract infection. The associated drugs were Meropenem, Piperacillin
and Tazobactam with a possible combined effect of these three drugs that resulted in systemic involvement requiring intensive
monitoring and prompt treatment. The objective of reporting this case is to focus on the his Conclusion tory that AGEP following
injection meropenem and Piptaz led to systemic complications and dermatologists must be aware of such rare adverse effect.
Accurate diagnosis and prompt treatment in adjunct with can reduce the mortality as in our case.
INVESTIGATING ASYMPTOMATIC CORONARY ARTERY DISEASE IN PATIENTS WITH ISCHAEMIC STROKE: AN UNDETECTED THREAT
Authors: Hussain Nazar
Published: September 2023

Background: Ischaemic stroke is a leading cause of mortality and disability worldwide, often related to
insufcient blood ow due to cerebral artery blockage. Recent evidence suggests a complex association
between ischaemic stroke and cardiovascular diseases, including coronary artery disease (CAD). Asymptomatic CAD, which
remains undiagnosed and untreated, can lead to recurrent cardiovascular events, making it vital to investigate its prevalence in
ischaemic stroke patients. Methods: We conducted a cross-sectional observational study on 240 ischaemic stroke patients,
excluding those with prior CAD or cardiac events. Demographic data, stroke characteristics, and risk factors were collected.
Cardiac evaluations, including 12-lead ECG and echocardiography, were performed to assess asymptomatic CAD. Results:
The prevalence of asymptomatic CAD in ischaemic stroke patients was 24.2%. Age (p < 0.001) and risk factors, such as
hypertension (OR 2.62, 95% CI: 1.40 - 4.90) and smoking (OR 2.10, 95% CI: 1.17 - 3.77), were signicantly associated with the
coexistence of asymptomatic CAD and stroke. Conclusion: Asymptomatic CAD is relatively common in ischaemic stroke
patients.Early detection and management of asymptomatic CAD in stroke patients may improve overall patient outcomes and
reduce the risk of future cardiovascular events.
ADENOID CYSTIC CARCINOMA OF UTERINE CERVIX IN A YOUNG PATIENT: A CASE REPORT

Published: September 2023

Adenoid cystic carcinoma of the cervix is a very rare condition that occurs more frequently in
postmenopausal women, although it can occur infrequently in people under the age of 40. In the present
case, a 29-year-old woman complained mainly of post-coital bleeding and bloody vaginal discharge. Per speculum
examination revealed a rm mass in the uterine cervix. Ultrasonography revealed a 2.4 cm x 1.9 cm hypoechoic lesion in the
posterior lip of the cervix. Liquid based cytology was suggestive of squamous cell abnormality ASCUS. On HPV testing
HPV16/31 was detected high, while HPV18/45 was not detected. The diagnosis of adenoid cystic carcinoma was conrmed by
the histopathological examination of the cervical biopsy. Immunohistochemistry showed tumor cells with positive expression of
p16, p63, and S-100. We report this case because of its rarity, particularly in young patients.
REFRACTORY IDIOPATHIC MULTICENTRIC CASTLEMAN DISEASE: A CASE REPORT

Published: September 2023

Castleman disease (CD) is a rare disease which includes a heterogeneous group of disorders that share
morphological features, such as HHV-8-negative idiopathic multicentric CD (iMCD). We describe the case
of a man affected by iMCD who develops ascites during anti-IL-6 treatment with siltuximab. The etiology of ascites was not
related to any other conditions, such as hepatic disease or venous thrombosis. We modied therapy adding a short course of
steroid and reducing the time intervals of siltuximab, obtaining a sustained improvement of the clinical picture. This case is of
particular interest because it suggests that a second line therapy might be postponed in iMCD, a disease in which it is difcult to
recommend a preferred second line for patients who relapse after anti-IL-6-based therapies.
BURKITT LYMPHOMA: UNPACKING THE COMPLEXITIES OF DIAGNOSIS AND MANAGEMENT
Authors: Marcela Vargas Olaya Diana
Published: September 2023

This comprehensive review explores the pathogenesis, clinical features, pathology, and diagnosis of
Burkitt Lymphoma (BL). BL arises from B-cells within the germinal center and is driven by the constitutive
expression of the MYC proto-oncogene on chromosome 8q24, leading to deregulation of cellular processes like cell growth,
division, and apoptosis. The characteristic chromosomal translocation involving MYC is a result of errors during
immunoglobulin gene diversication in B-cells. Additional mutations complement MYC deregulation. EBV infection is
implicated in African BL cases and some sporadic and immunodeciency-associated cases. Clinically, BL presents with rapid
tumor growth and spontaneous tumor lysis, resulting in elevated LDH and uric acid levels. The three clinical forms are endemic,
sporadic, and immunodeciency-associated, each with distinct characteristics. Accurate diagnosis relies on
anatomopathological evaluation and identication of MYC translocations. Treatment involves intensive chemotherapy with
CNS prophylaxis, and rituximab has been shown to improve outcomes. This review emphasizes the need for precise diagnosis
and tailored management to combat this aggressive malignancy effectively.
