Barriers to and Facilitators of Collegiate Athletes Seeking Mental Health Services
Authors: Yoon Julian Jehoon , Petrie Trent
Published: April 2023

Context

Approximately 1 in 5 student-athletes experience some type of mental health concern. However, fewer than half of student-athletes who report mental health concerns seek mental health treatment (ie, psychotherapy or medication). Data concerning barriers to student-athletes seeking mental health care are limited but suggest that stigma is the primary reason. Further, whether having shared identities with their sport psychologists (eg, race and gender) encourages student-athletes to seek help has been minimally explored.

Objectives

To determine the frequency of internal and external barriers to athletes seeking mental health care and examine the importance of athletes and sport psychologists sharing identities as a facilitator of seeking help.

Design

Cross-sectional study.

Setting

Collegiate athletics.

Patients or Other Participants

A total of 266 student-athletes (53.8% women, 42.5% White) from a National Collegiate Athletic Association Division I university.

Main Outcome Measures

Student-athletes responded to 9 binary (yes or no) prompts related to internal barriers (eg, beliefs and attitudes about mental health) and 7 reflecting external barriers (ie, different stakeholders, such as the head coach). Regarding facilitators of mental health help-seeking, student-athletes rated how important it was for them to share each of 10 identities with their sport psychologist from 1 (not at all important) to 5 (extremely important). All identified barriers and facilitators were derived from existing research.

Results

Differences were found in athletes’ ratings of internal and external barriers. For example, a belief in one’s own reliance and not having enough time were significant barriers, as was their head coach having a negative attitude about the importance of mental health. Female student-athletes rated sharing a gender identity with their sport psychologist as more important than did male student-athletes.

Conclusions

Despite efforts by the National Collegiate Athletic Association to reduce the stigma surrounding mental health, persisting barriers within collegiate sports may keep athletes from seeking help.

Published: April 2023

Collegiate student-athletes experience an increasing number of mental health concerns. To help address these concerns and provide high-quality health care for student-athletes, institutions of higher education are being encouraged to create interprofessional health care teams that are specifically dedicated to managing mental health. We interviewed 3 interprofessional health care teams who collaborate to manage routine and emergency mental health conditions in collegiate student-athletes. Teams represented all 3 National Collegiate Athletics Association (NCAA) divisions and included athletic trainers, clinical psychologists, psychiatrists, dietitians and nutritionists, social workers, nurses, and physician assistants (associates). The interprofessional teams indicated that the existing NCAA recommendations helped to solidify members and roles of the mental health care team; however, they all believed their teams would benefit from more counselors and psychiatrists. Teams had different mechanisms for referral and accessing mental health resources on their campuses, which may make on-the-job training for new members of the team an organizational necessity.
Maximal Lower Limb Strength in Patellar Tendinopathy: A Systematic Review With Meta-Analysis
Authors: Obst Steven J. , Peterson Benjamin , Heales Luke J.
Published: April 2023

Objective

To investigate whether lower limb strength is reduced in people with patellar tendinopathy (PT) compared with asymptomatic control individuals or the asymptomatic contralateral limb.

Data Sources

MEDLINE, PubMed, Scopus, and Web of Science.

Study Selection

To be included in the systematic review and meta-analysis, studies were required to be peer reviewed, published in the English language, and case control investigations; include participants with a clinical diagnosis of PT and an asymptomatic control or contralateral limb group; and include an objective measure of lower limb maximal strength.

Data Extraction

We extracted descriptive statistics for maximal strength for the symptomatic and asymptomatic limbs of individuals with PT and the limb(s) of the asymptomatic control group, inferential statistics for between-groups differences, participant characteristics, and details of the strength-testing protocol. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool for analytical cross-sectional studies.

Data Synthesis

Of the 23 included studies, 21 reported knee strength, 3 reported hip strength, and 1 reported ankle strength. Random-effects models (Hedges g) were used to calculate the pooled effect sizes (ESs) of muscle strength according to the direction of joint movement and type of contraction. The pooled ESs (95% CI) for maximal voluntary isometric contraction knee-extension strength, concentric knee-extension strength, and concentric knee-flexion strength were 0.54 (0.27, 0.80), 0.78 (0.30, 1.33), and 0.41 (0.04, 0.78), respectively, with all favoring greater strength in the asymptomatic control group. Researchers of 2 studies described maximal eccentric knee-extensor strength with no differences between the PT and asymptomatic control groups. In 3 studies, researchers measured maximal hip strength (abduction, extension, and external rotation), and all within-study ESs favored greater strength in the asymptomatic control group.

Conclusions

Isometric and concentric knee-extensor strength are reduced in people with PT compared with asymptomatic control individuals. In contrast, evidence for reduced eccentric knee-extension strength in people with PT compared with asymptomatic control individuals is limited and inconsistent. Although evidence is emerging that both knee-flexion and hip strength may be reduced in people with PT, more examination is needed to confirm this observation.
Impact of Dosimetric Parameters on Interplay Effects in 6 MV Flattening Filter-Free Photon Beams to Treat Lung Cancer
Authors: Poolnapol Vanida , Sanghangthum Taweap , Keawsamur Mintra
Published: April 2023

Context:

Interplay effects have become the significant problem in lung cancer radiotherapy. Since these effects yield dose variation within the target and surrounding tissues.

Aim:

The aim of this study is to investigate the effect of the dosimetric parameters of interplay effects in 6 MV flattening filter-free (FFF) photon beams for lung cancer.

Settings and Design:

This study performed planning, measurement, and data analysis sections for examining different breathing amplitudes and phases, doses, dose rates, field sizes, and fractionations.

Subjects and Methods:

Standard and clinical plans were created on the eclipse treatment planning system. The static and dynamic measurements were performed using a robotic platform and two-dimensional (2D) diode array. The gamma passing rates were defined as the percent of dose variation caused by the interplay effects.

Statistical Analysis Used:

Unpaired t-test.

Results:

The outcomes showed three trends between gamma passing rates (γ) and dosimetric parameters. First, a decreasing trend was breathing amplitudes. The lowest γ of maximum amplitudes (2 cm) in both one dimensional and 2D were <25%. Second, an increasing trend was field sizes. The lowest γ of minimum field size (4 cm × 4 cm2) was <55%. Third, constant outcomes were breathing phases, doses, dose rates, and a number of fractions. The γ values of these factors were 53.1%, 55.1%, 34.7%, and 36.7%, respectively.

Conclusions:

Lung tumor motion-induced interplay effects in 6 MV FFF photon beams are more pronounced for higher breathing amplitudes and smaller field sizes.

Authors: Sabri Adila Hanim Aminordin , Abdul Aziz M. Z. , Olukotun S. F. , Tajudin S. M.
Published: April 2023

Purpose:

Calculation of photon attenuation is necessary for the selection of shielding materials for an irradiation facility.

Methods and Materials:

In this work, a Monte Carlo simulation was utilized to assess the effectiveness of clay-polyethylene mixture and clay as the radiation shielding materials for high-energy gamma sources (Ir-192). Ordinary concrete was also studied as the benchmark.

Results:

The calculated linear attenuation values for ordinary concrete are within 0.44% of the standard XCOM value for 380 keV photon. In the case of a multienergy Ir-192 gamma source, the calculated linear attenuation coefficient (μ) for ordinary concrete is 15.5% and 7.25% higher than clay and fabricated clay-polyethylene, respectively. Meanwhile, the μ value for fabricated clay-polyethylene is 8.3% higher than that of clay.

Conclusion:

In conclusion, a 10 cm thickness of clay and clay-polyethylene mixture is sufficient to attenuate 87% and 89% of photons from Ir-192 source. The calculated linear attenuation coefficients for the three shielding materials are also consistently higher, about 7.5%, than that of the XCOM value for 380 keV photon.
Segmentation of Organs and Tumor within Brain Magnetic Resonance Images Using K-Nearest Neighbor Classification
Authors: Yoganathan S. A. , Zhang Rui
Published: April 2023

Purpose:

To fully exploit the benefits of magnetic resonance imaging (MRI) for radiotherapy, it is desirable to develop segmentation methods to delineate patients' MRI images fast and accurately. The purpose of this work is to develop a semi-automatic method to segment organs and tumor within the brain on standard T1- and T2-weighted MRI images.

Methods and Materials:

Twelve brain cancer patients were retrospectively included in this study, and a simple rigid registration was used to align all the images to the same spatial coordinates. Regions of interest were created for organs and tumor segmentations. The K-nearest neighbor (KNN) classification algorithm was used to characterize the knowledge of previous segmentations using 15 image features (T1 and T2 image intensity, 4 Gabor filtered images, 6 image gradients, and 3 Cartesian coordinates), and the trained models were used to predict organ and tumor contours. Dice similarity coefficient (DSC), normalized surface dice, sensitivity, specificity, and Hausdorff distance were used to evaluate the performance of segmentations.

Results:

Our semi-automatic segmentations matched with the ground truths closely. The mean DSC value was between 0.49 (optical chiasm) and 0.89 (right eye) for organ segmentations and was 0.87 for tumor segmentation. Overall performance of our method is comparable or superior to the previous work, and the accuracy of our semi-automatic segmentation is generally better for large volume objects.

Conclusion:

The proposed KNN method can accurately segment organs and tumor using standard brain MRI images, provides fast and accurate image processing and planning tools, and paves the way for clinical implementation of MRI-guided radiotherapy and adaptive radiotherapy.
Effect of troxerutin on the expression of genes regulating mitochondrial biogenesis and microRNA-140 in doxorubicin-induced testicular toxicity
Authors: Mokhtari Behnaz , Abdi Arezou , Athari Seyed Zanyar , Nozad-Charoudeh Hojjatollah , Alihemmati Alireza , Badalzadeh Reza
Published: April 2023

Background:

Application of doxorubicin (DOX) in cancer patients is limited due to its dose-dependent toxicity to nontarget tissues such as testis and subsequent infertility. Due to limitation of our knowledge about the mechanisms of DOX toxicity in the reproductive system, reduction of DOX-induced testicular toxicity remains an actual and primary clinical challenge. Considering the potentials of troxerutin (TXR) in generating a protective phenotype in many tissues, we aimed to examine the effect of TXR on DOX-induced testicular toxicity by evaluating the histological changes and the expression of mitochondrial biogenesis genes and microRNA-140 (miR-140).

Materials and Methods:

Twenty-four adult male Wistar rats (250–300 g) were divided in groups with/without DOX and/or TXR. DOX was injected intraperitoneally at 6 consecutive doses over 12 days (cumulative dose: 12 mg/kg). TXR (150 mg/kg/day; orally) was administered for 4 weeks before DOX challenge. One week after the last injection of DOX, testicular histopathological changes, spermatogenesis activity, and expression of mitochondrial biogenesis genes and miR-140 were determined.

Results:

DOX challenge significantly increased testicular histopathological changes, decreased testicular expression profiles of sirtuin 1 (SIRT-1) and nuclear respiratory factor-2 (NRF-2), and increased expression of miR-140 (P < 0.05 to P < 0.01). Pretreatment of DOX-received rats with TXR significantly reversed testicular histopathological changes, spermatogenesis activity index, and the expression levels of SIRT-1, peroxisome proliferator-activated receptor-γ coactivator 1-alpha (PGC-1α), NRF-2, and miR-140 (P < 0.05 to P < 0.01).

Conclusion:

Reduction of DOX-induced testicular toxicity following TXR pretreatment was associated with upregulation of SIRT-1/PGC-1α/NRF-2 profiles and better regulation of miR-140 expression. It seems that improving microRNA-mitochondrial biogenesis network can play a role in the beneficial effect of TXR on DOX-induced testicular toxicity.

Authors: Liang Yun-Fang , Wang Si-Qi , Pan Zhao-Yu , Deng Zhi-He , Xie Wen-Rui
Published: April 2023

Background:

The prognosis of and occurrence of complications in patients with different clinical features of cirrhosis differ, and cirrhosis with different etiologies has varying clinical characteristics. The aim of this study was to describe the liver function markers, hepatic complications, and psychological features differentiating patients with hepatitis B virus (HBV) infection-related and alcohol-related cirrhosis.

Materials and Methods:

This was a retrospective and observational study that analyzed the medical data of inpatients with alcohol-related or HBV infection-related cirrhosis from May 2014 to May 2020. Markers of liver function, portal hypertension, and psychological symptoms were compared between the two groups.

Results:

Patients with alcohol-related cirrhosis showed higher Self-Rating Anxiety Scale scores and prevalence of hypoproteinemia, fatty liver, and depression than those with HBV infection-related cirrhosis (all P < 0.05). After adjustment for potential confounders, patients with alcohol-related cirrhosis also showed higher risks of increased total cholesterol (odds ratio [OR] =2.671, 95% confidence interval [CI]: 1.160–6.151, P = 0.021), increased high-density lipoprotein-cholesterol (OR = 2.714, 95% CI: 1.009–7.299, P = 0.048), and fatty liver (OR = 2.713, 95% CI: 1.002–7.215, P = 0.048); however, splenomegaly and splenectomy were significantly associated with HBV infection-related cirrhosis (OR = 2.320, 95% CI: 1.066–5.050, P = 0.034).

Conclusion:

Patients with alcohol-related cirrhosis were more likely to develop hyperlipidemia, fatty liver, and psychological symptoms, whereas those with HBV-related cirrhosis had a higher risk of splenomegaly.
Comparison of the effect of ursodeoxycholic acid and multistrain synbiotic on indirect hyperbilirubinemia among neonates treated with phototherapy: A double-blind, randomized, placebo-controlled clinical trial study
Authors: Babaie Elahe , Hassanpour Kazem , Aldaghi Mitra , Sahebkar Mohammad
Published: April 2023

Background:

This study was aimed at evaluating the effect of ursodeoxycholic acid (UDCA) and multistrain synbiotic on indirect hyperbilirubinemia among neonates treated with phototherapy.

Materials and Methods:

This double-blind, randomized clinical trial was conducted on 120 subjects presenting with indirect hyperbilirubinemia in 2019. Subjects were randomly divided into three groups of synbiotic, UDCA, and control. The synbiotic group received five drops/day of synbiotic in addition to phototherapy. UDCA group received 10 mg/kg/day of Ursobil divided every 12 h in addition to phototherapy. The Control group received a placebo (water) in addition to phototherapy. Phototherapy was discontinued when the bilirubin levels reached <10 mg/dL. Total bilirubin levels were measured using the diazo method at 12, 24, and 36 h after hospitalization. This study used repeated measure analysis of variance and post hoc tests.

Results:

The mean total of bilirubin was substantially decreased in both synbiotic and UDCA groups as compared to the control group at 24 h after hospitalization (P < 0.001). Moreover, the Bonferroni post hoc test showed significant differences regarding the mean total of bilirubin between the three groups (P < 0.05) except for the association between UDCA and synbiotic at 24 h after hospitalization (P > 0.99).

Conclusion:

Findings suggest that UDCA and synbiotic administration alongside phototherapy are more effective in reducing bilirubin levels as compared to phototherapy alone.
Comparison of intrathecal bupivacaine with different doses of clonidine for spinal anesthesia in adults
Authors: Dattatri Sangeetha , Hareesh S. B. , Ashokanand Devanahalli V.
Published: April 2023

Background:

Evaluating the optimal dose of intrathecal clonidine adjuvant has a great impact on day-to-day practice of anesthesia, as spinal anesthesia is one of the most commonly performed anesthetic procedure.

Objectives:

Evaluate for the minimal dose of intrathecal clonidine as an adjunct to bupivacaine heavy for spinal anesthesia that can produce optimal sensory and motor blockade with minimal hemodynamic effects.

Methods:

Randomized control trials carried out on adult patients, of both genders undergoing elective infraumbilical surgeries under spinal anesthesia with bupivacaine heavy and different doses of clonidine having ethical committee approval were included and articles published in non-English languages were excluded. Databases (PubMed and Google Scholar) and websites of the Indian Journal of Anaesthesia and anesthesia essays and researches journals were systematically searched and interpreted in accordance with the PRISMA guidelines. Quality assessment was done using the Risk of Bias assessment 2.O tool. The mean time taken for the onset of sensory and motor blockade, mean duration of sensory and motor blockade and significant adverse effects were the key outcome variables. Nonstatistical synthesis of quantitative data of the selected articles was done.

Results:

The efficacy in terms of sensory and motor blockade was comparatively more with 1 μg/kg of intrathecal clonidine than with lower doses, however, cardiovascular adverse effects were dose-dependent, with 15 μg intrathecal clonidine causing least cardiovascular disturbance.

Conclusion:

15–30 μg intrathecal clonidine as an adjunct to bupivacaine heavy would produce optimal sensory and motor block with minimal hemodynamic disturbances.
Evaluation of sub-brow approach to the frontozygomatic suture for Open Reduction and Internal Fixation (ORIF) of Zygomatico maxillary complex (ZMC) fractures: A prospective cohort study
Authors: Pandya Avadh R. , Panneerselvam Elavenil , Vignesh Arun , Krishnakumar V B Raja
Published: April 2023

Introduction:

Contemporary incisions used to access the frontozygomatic (FZ) sutures are the lateral brow and upper blepharoplasty incisions which are associated with specific limitations and complications. The authors describe the use of sub-brow incision as an alternate approach for exposure of the FZ region.

Methods:

This is a prospective cohort study involving patients requiring surgical management of zygomatico maxillary complex (ZMC) fractures with fixation at FZ suture alone or along with fixation at infra-orbital rim and/or zygomaticomaxillary buttress. A sub-brow incision was used to expose the fracture and fixation was done with a 4-hole miniplate. The parameters evaluated were specific to the FZ region (sub-brow incision), namely surgical access, bleeding, fracture exposure time, post-operative scar, and pain. Each patient was reviewed on 1st, 5th, 7th, 10th, 30th, and 90th day.

Results:

The study sample included eight male patients. The mean age was 30 years. The sub-brow incision demonstrated favorable postoperative outcomes; adequate exposure was achieved in all 8 patients. The scar formation was found to be higher on the 7th day and the least scar formation was seen by the third month. The mean pain score was found to be high on first post-operative day and the least pain was seen by the 10th day. The mean score of surgical field bleeding was found to be 1.75 which signified mild bleeding according to Fromme’s scale. The mean time taken for adequate exposure of the fracture was 6.62 min. All the assessment parameters were statistically significant (P value <0.01).

Conclusion:

Sub-brow incision is an effective approach for ORIF of zygomatic fractures at FZ suture. The technique is quick, simple, and associated with minimal complications.

Authors: Singh Akhilesh Kumar , Sharma Naresh Kumar , Mishra Nitesh , Mahajan Arjun , Krishnan Aswathi , Rajpoot Ravina , Kumar Janani Anand , Pandey Arun
Published: April 2023

This systematic review mainly focuses on the effects of curcumin on oral cancer cells at the molecular level and summarizes the results of the studies. We searched and analyzed various databases such as Pub Med, ProQuest, Google Scholar, Science Direct, and Scopus. Searches were conducted from 2006 to 2021. This systematic review evaluated various effects of curcumin on oral cancer at the molecular level. All the studies related to the effects of curcumin on oral cancer, both in-vivo and in-vitro, were included. After abstract and text screening a total of 13 articles were finally selected for the study based on the inclusion and exclusion criteria. All most all the included studies reported that after treating the cell lines with curcumin there is a reduction in cell proliferation and cell growth, analyzed using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. Curcumin also induces S phase cell cycle arrest and also prevents Tregs migration. The curcumin reverses the process of epithelial mesenchymal transition (EMT) back to mesenchymal epithelial transition (MET). From this review, it is concluded that curcumin inhibited proliferation, migration, invasion, and metastasis, and induced apoptosis via modulating multiple signaling pathways in oral cancer cell lines. But further clinical trials are needed for a detailed evaluation of the effects of curcumin on patients with oral cancer.

Authors: Chugh Ankita , Kaur Amanjot , Bhardwaj Pankaj , Vishnoi Jeewan Ram , Joshi Nitin , Kumar Shailendra , Chopane Shivkumar , Kumar Pravin
Published: April 2023

Purpose and Objectives:

One of the main causes of the increasing oral cancer (OC) burden in India is a lack of awareness and a significant gap in knowledge about risk factors and symptomology of OC.

Materials and Methods:

A questionnaire-based cross-sectional study was to evaluate the knowledge and awareness about OC among 500 random patients presenting for care at a tertiary hospital in western Rajasthan which serves a wide area of western, northern, and central Rajasthan.

Results:

A total of 446 participants, among which 83.6% were males enrolled in the study. Much to our despair, the results showed 35.23% of the participants (P = 0.007) started their habit at age <15 years. Nearly 60.3% of the participants were well aware of the harmful temporary or permanent effects of the tobacco. Around 40.85% of the participants taking tobacco products were ignorant about their changes in the tissues (site of tobacco placement). TV and Radio (50.5%) were the main source of information of the ill effects of tobacco and form a major contribution in public awareness. More than 90% of the participants had read the warnings on the tobacco packets. No doubt participants have knowledge about the ill effects of tobacco still there was a lack in behavioral modifications for tobacco cessation, leading to nonsuccess in quitting, with actual nonunderstanding about the ill effects of tobacco and overall lack of belief in the tobacco control measures.

Conclusion:

Our findings have found a gap in the awareness efforts of OC for the general population and will make public health professionals, clinicians, policymakers, and government a better judge and motivate them to strengthen existing national tobacco control efforts.
Evaluation of effect of single vector mandibular distraction for correction of postankylotic mandibular hypoplasia requiring multiplanar correction: A prospective case series
Authors: Singhal Mayank , Goyal Manoj , Mittal Neeti
Published: April 2023

Introduction:

Uniplanar devices have been criticized for being insufficient to correct complex mandibular deformities and associated problems of open bite and cross bite. The use of oblique vector to correct complex multiplanar deformities using uniplanar mandibular distraction devices is the uniqueness of the present case series.

Aim and Objective:

The aim of the present case series is to describe the successful use of uniplanar mandibular distraction devices for the correction of complex multiplanar deformities.

Material and Method:

The technique of callous molding was employed to overcome any open bite. A total of 40 mandibular distractors in 20 patients (mean age 13 ± 2.67 years) were placed on the mandible for correction of the facial deformity associated with the lower jaw(mandible) in vertical, horizontal and/or sagittal plane, secondary to temporomandibular joint ankylosis. The distraction was done before and after the gap arthroplasty in 15 and 5 patients, respectively. A latency period of 3–5 days was applied, and distraction was performed at a rate of 1 mm/day with the rhythm of 0.5 mm twice daily.

Results:

The significant lengthening was observed in both mandibular height (Ar Go) (50.40 ± 1.52 mm from 38.80 ± 4.38mm, P = 0.006) as well as in mandibular corpus length (Go Pg) (79.40 ± 2.28 from 58.80 ± 4.09, P = 0.001). Statistically significant changes in mandibular dimensions, facial proportions, and soft tissue profile were seen, which was assessed with the help of COGS analysis done on lateral cephalogram taken preoperatively and postoperatively.

Conclusion:

With intelligent vector planning and callus molding multiplanar complex deformities can be corrected by using semiburieduniplanar devices.

Peran Akuntansi Dalam Bisnis Dalam Rangka Membangun Jiwa Wirausaha Di Usia Muda Pada Siswa SMA Tunas 1 Jakarta
Authors: Kurniawan Lydia
Published: April 2023

Accounting is an information system that provides stakeholder reports on economic activity and company conditions. The most basic role of accounting in business is its ability to provide various information and answers related to all kinds of financial data. There are four important roles of accounting in business that must be known, namely first as a financial controller, second as a provider of financial information, third to assist stakeholders in making decisions, and fourth as a liaison with third parties. An entrepreneurial spirit is a spirit of independence to seek sources of income by opening a business or channeling one's creativity. Entrepreneurial spirit is instilled since someone starts to realize that money is important. By instilling an entrepreneurial spirit, someone will learn to be more independent, learn to process the results of skills to become a work that can be sold in the form of food, clothing, services, or other goods. The ability to master accounting is one of the supports in business activities to achieve peak performance. Without accounting in our business, it will have a negative impact on the management of business finances.

 

Akuntansi adalah sistem informasi yang menyediakan laporan pemangku kepentingan tentang aktivitas ekonomi dan kondisi perusahaan, Peran akuntansi dalam bisnis yang paling mendasar adalah kemampuannya dalam menyediakan berbagai informasi dan jawaban yang berhubungan dengan segala macam data keuangan. Terdapat empat peran penting akuntansi dalam bisnis yang wajib diketahui yaitu pertama adalah sebagai pengendali keuangan, kedua sebagai penyedia informasi tentang keuangan, ketiga membantu para stakeholders dalam mengambil keputusan, dan keempat sebagai penghubung dengan pihak ketiga. Jiwa wirausaha adalah jiwa kemandirian untuk mencari sumber penghasilan dengan membuka usaha ataupun menyalurkan kreativitas yang dimiliki seseorang. Jiwa kewirausahaan ditanamkan sejak seseorang mulai sadar bahwa uang itu penting. Dengan menanamkan jiwa kewirausahaan maka  sesorang akan belajar  lebih mandiri, belajar mengolah hasil dari keterampilan untuk dijadikan sebuah karya yang dapat dijual berupa makanan, pakaian, jasa, atau barang-barang lain. Kemampuan menguasai akuntansi menjadi salah satu penyokong dalam kegiatan bisnis untuk mencapai performa puncaknya. Tanpa adanya akuntansi di bisnis kita akan berdampak buruk dalam  pengelolaan keuangan bisnis yang dijalankan.

Endüstriyel Kontrol Sistemleri (ICS) veya SCADA ağları, mimarileri tescilli donanım, yazılım ve protokollerden standart ve açık kaynaklara geçtikçe siber saldırıların hedefi haline gelmektedir. Büyük ölçekli sensör verileri, olağan dışı durumları ve siber saldırı olaylarını sürekli olarak izlenebilir kılmaktadır. Mevcut denetimsiz makine öğrenimi yaklaşımları, anormallikleri tespit etmek için sistemdeki sensörler arasındaki uzamsal-zamansal korelasyonu ve diğer bağımlılıkları tam olarak kullanmamıştır. Bu makale, Konvolüsyonel Sinir Ağı (CNN), Tekrarlayan Sinir Ağı (RNN), Stacked Autoencoder (SAE), Uzun Kısa Süreli Bellek gibi çeşitli mimarilerin SCADA ağlarındaki anomalilerin tespit edilmesinde kullanılan yaklaşımların incelenmesidir. Ayrıca makalede bu yöntemlerin incelenmesine ek olarak Uzun-Kısa Süreli-Bellek Tekrarlayan Sinir Ağlarını (LSTM-RNN) temel modeller (yani, üreteç ve ayrımcı) olarak kullanan, Üretken Çelişkili Ağlara (GAN'lar) dayalı denetimsiz çok değişkenli bir anomalli tespit yöntemini detaylı olarak sunmaktadır.

his work gives a comparison between two approaches used for improving search operation speed by using FPGA-based Binary Content Addressable Memory (BiCAM), which is a parallel type of computer memory that quickly searches for and retrieves specific data stored within the memory by assigning a unique address to each piece of data. This hardware-based technique is more efficient than traditional software-based techniques such as Linear, Binary, and hash-based. The FPGA-based BiCAM is implemented using two different approaches: using Flip-flops and Block Random Access Memory as the memory element. The performance of these implementations is evaluated through Time complexity analysis, resource utilization, and search speed. The results indicate that the Flip-flops approach is worse in terms of search speed and resource utilization compared to the other approach. With the current increasing demand for faster and more efficient search operations, this approach can play an important role in optimizing search operations.

Hızla gelişmekte olan bilgisayar teknolojisi sayesinde çeşitli tekniklerle dijital

ses, görüntü ve video dosyaları üzerinde modifikasyonlar yapılabilmektedir.

Bu modifikasyonlar doğrudan dosya içeriğinde olabileceği gibi bazen de meta

data üzerinde olabilmektedir. Bu bağlamda dijital medyaların adli analizi

büyük önem arz etmektedir. Elektrik şebeke frekansı (ENF) tabanlı adli analiz

yaklaşımı dosya bütünlük kontrolünde ve dosyaların kayıt zamanı tespitinde

kullanılabilen önemli bir araçtır. ENF sinyali kestiriminde en çok tercih edilen

yöntemlerden biri, kısa zamanlı Fourier dönüşümü (Short-Time Fourier

Transform - STFT) temelli yaklaşımdır. STFT yönteminde, pencere boyutu ve

kaydırma miktarı parametrelerinin seçimi büyük öneme sahip olup, kestirimi

yapılan ENF sinyali doğruluğunu, dolayısıyla da ENF tabanlı adli analiz

uygulamalarının performansını doğrudan etkileyebilmektedir. Bu çalışmada,

STFT parametreleri seçiminin, ENF tabanlı dosya kayıt zamanı doğrulamada

performansa ne derece etki ettiği araştırılmıştır. Farklı uzunluktaki ses

dosyaları, çeşitli STFT pencere boyutu ve STFT kaydırma miktarlarına göre

ayrı ayrı test edilerek karşılaştırmalı bir analiz yapılmıştır.

Çekişmeli Üretken Ağ (GAN), üretken bir derin öğrenme modeli olarak bilinir. Üretici (generator) ve ayırt edici (discriminator) yapılarından oluşmaktadır. Sentetik veri olarak bilinen GAN modeli çıktılarının oldukça başarılı örnekleri bilinmektedir. Farklı amaçlar ile kullanılabilen sentetik verilerin, başarılı bir şekilde üretilmesi durumunda insan gözü ile tespit edilebilmesi oldukça güç bir problemdir. Bu çalışmada farklı ve popüler Evrişimli Sinir Ağı (CNN) modellerinin öznitelik çıkarıcı olarak kullanıldığı, sentetik ve gerçek görüntüleri ayırt eden bu problem için Laplace filtresi ve benzemezlik tabanlı yeni bir CNN katmanı önerilmiştir. GAN modelinin farklı modeller üzerindeki başarı sonuçları tespit edilmiştir. Böylece, gözle ayırt edilemeyen sentetik verilerin tespiti için CNN modellerinden yararlanmanın uygun bir alternatif olduğu anlaşılmıştır. En iyi başarı %98.75 doğruluk oranıyla DenseNet ile elde edilmiştir.

İndis modülasyonlu dikgen frekans bölmeli çoğullama (OFDM-IM) sistemi yüksek spektral verimlilik, esneklik ve taşıyıcılar arası girişime karşı bağışıklık gibi üstün özellikleri ile öne çıkmaktadır. Fakat OFDM-IM sisteminde yüksek tepe gücü/ortalama güç oranı (PAPR) problemi bulunmaktadır. Yüksek PAPR, güç kuvvetlendiricilerinin doğrusal olmaması durumunda, iletilen sinyali bozarak sistem performansını olumsuz etkilemektedir. Bu makalede, sistemde oluşan yüksek PAPR’ ı seçici eşleme (SLM) yöntemi kullanılarak düşürmek hedeflenmektedir. Bilgisayar simülasyon sonuçları OFDM-IM sisteminde kullanılan SLM yönteminin, orijinal sisteme kıyasla PAPR değerini önemli ölçüde düşürdüğünü göstermektedir. Ayrıca OFDM-IM sisteminde alt taşıyıcı sayısı, faz rotasyon faktörü ve modülasyon indisi parametrelerindeki değişiminin sistemin PAPR performansına etkisi de incelenerek değerlendirmeler yapılmıştır.
FDCCII Based New Memcapacitor Emulator Circuit with Electronically Tunable

Published: April 2023

Since memcapacitor and meminductor elements have not been produced yet, emulator circuits are used to examine their application areas. In this paper, a new FDCCII-based grounded memcapacitor emulator circuit is presented. The proposed circuit consists of one FDCCII, one multiplier, three capacitors and two MOSFETs. These two MOSFETs are utilized as electronic resistors in the circuit. The variable part of memconductance can be adjusted electronically and the proposed memcapacitor possesses an incremental-decremental adjustable structure. Moreover, it contains fewer active elements than many memcapacitor emulator studies in the literature. The proposed circuit was designed in LTspice, and frequency response, temperature, and Monte Carlo analyses were performed. In addition, the electronic resistor has been simulated at various values, demonstrating that the circuit is electronically adjustable. The simulation results are consistent with the mathematical results presented in the article.

Intersections in urban areas can often cause significant traffic delays due to the multiple directions of traffic flow. The Kathmandu Valley experiences chronic gridlock and congestion. This study aims to improve traffic flow at two busy intersections (Kanti Children's Hospital and Shital Niwas) in Kathmandu Valley, Nepal through evaluation of the existing traffic flow condition and reducing delays and queues using various alternatives and including signal coordination. A survey was carried out to collect morning peak hour traffic volume and geometrical features of the two intersections and developed a signalized intersection model in SIDRA software. The model was validated based on observed and modelled queue lengths for each approach, and the existing performance of the intersections was evaluated. Various alternatives were then developed to improve the performance of the intersections. Results showed that coordinating the signal systems significantly reduced the average delay time and maximum queue length at both intersections. Specifically, the average delay time was reduced from 106 seconds per vehicle to 26.5 seconds per vehicle at the Shital Nivas intersection and from 43.1 seconds per vehicle to 21.7 seconds per vehicle at Kanti Children's Hospital intersection. Similarly, the maximum queue length was reduced from 744.7 meters to 122 meters at the Shital Nivas intersection and from 456.2 meters to 147.7 meters at Kanti Children's Hospital intersection.

Published: April 2023

Sanayileşmenin artmasıyla beraber su kıyılarına çeşitli tesisler kurulmaktadır. Bu tesisler, deniz ekosistemini olumsuz yönde etkilediği bazı durumlar vardır. Bunlardan biri de ısıl deşarjlardır. Yapılan ısıl deşarjlar deniz ekosisteminde olumsuzluklar yaratabilmektedir. Isıl deşarjların oluşma nedeni; enerji santralleri, Demir-Çelik fabrikaları gibi tesislerin soğutma işlemini yapmak için deniz gibi büyük su kütlelerini soğutucu olarak kullanmalarıdır. Bu tür olumsuzlukların oluşmaması için deşarj suyunun sıcaklığına bağlı olarak alıcı ortamın sıcaklık değişimi yasalar ile kısıtlanmıştır. Bundan dolayı en iyi seyrelmeyi ve en ekonomik olan sistemin belirlenmesi önem kazanmıştır. Bunu öğrenebilmek için 3 farklı sistem laboratuvar ortamında test edilmiştir. İlk deneyimizde serbest düşen jetler, ikinci deneyimizde su yüzeyinden suya paralel jetler oluşturulmuş ve üçüncü deneyimizde ise su yüzeyine ikincil bir hazne yapılarak üç delikten deşarj yapılmıştır. Jetlerin oluşturduğu termal bulutlar incelenmiştir.
The 51st reason why there are so few Māori in science
Authors: Stewart Georgina
Published: April 2023

A 2022 paper by Tara McAllister lists ‘50 reasons why there are no Māori’ in university science departments, giving a range of examples of Māori experience of personal and structural racism within the edifices of science and research in Aotearoa New Zealand. In support of McAllister and the larger social and intellectual project of Kaupapa Māori to which her work contributes, this commentary offers ethnic socio-economic inequality as the ‘51st reason’ and explains how it causes the permanent disparity of very few working scientists who identify as Māori.
