Background: The aim of the research was to assess the body mass index in women involved in various forms of physical activity including dancing (Tango-T), running (Runners-R) and exercising in fitness clubs (Fitness-F) compared to sedentary women (Control-C). An additional aim was to investigate the prevalence of disorders of the menstrual cycle in physically active women with body mass index <18.5.Methods and material: 683 women participated in the study (T:143, R:215, F:120, C:205). In each group, the mean body mass index value and the percentages of obese, overweight, normal-weight, and underweight women were calculated. The effect of age and training parameters on body mass index and the prevalence of menstrual disorders in underweight women were analyzed. The author’s questionnaire was used in the research.Results: The mean body mass index (BMI) [kg/m2] was lower in the T (21.52.3, R:22.33.0) and F (21.93.0) groupscompared to the C group (23.64.7). In the T group (89.5%, R:76.7%) and F group (75.8%), more women had normal BMI than in the C group 55.6%. The strongest correlations between age and BMI occurred in the C group (r=0.41;p<0.001) and were weaker in the other groups: R:(r=0.18;p<0.01), T:(r=0.14;p<0.01), and F:(r=0.01;p<0.05). Menstrual cycle disorders in underweight women in the F group (50.0%) were more frequent than in the C group (4.3%).

The MOOC model (Massive Open Online Course, for its acronym in English) has emerged as an innovative alternative for university education, allowing massive access to online courses taught by renowned institutions. This model is characterized by its open, flexible and autonomous nature, which has generated a significant impact on the educational landscape. One of the main advantages of the MOOC is its ability to broaden access to university education. Through online platforms, anyone can enroll in courses taught by professors from world-renowned institutions. This has democratized education by removing geographic and economic barriers that often limit access to traditional education. In addition, the MOOC model offers flexibility in terms of hours and location. Students can learn at their own pace, access course materials anytime, anywhere, and tailor their learning process to their individual needs. This promotes autonomous learning and self-regulation, valuable skills in an ever-evolving educational environment. MOOCs cover a wide range of topics and disciplines, giving students the opportunity to explore various fields of study and gain knowledge in areas of specific interest to them. This encourages the diversity of content and the personalization of learning, since students can choose the courses that best suit their needs and educational goals. However, the MOOC model also presents challenges. The lack of interaction and personalized feedback, due to the large number of participants, can make it difficult to deepen the concepts and resolve specific doubts. Additionally, MOOC course completion rates are often low, raising questions about student engagement and motivation. Despite these challenges, the MOOC as an alternative model for university education has proven to be a valuable tool. It has allowed access to education to people from all over the world, promoting flexibility, diversity of content and autonomous learning. As MOOCs continue to be explored and improved, it is expected that they will continue to play an important role in the educational landscape, providing enriching and transformative learning opportunities.

Objectives. The main objective of this paper was to examine the perceptions of family physicians on the use of primary health care in Bosnia and Herzegovina during the COVID-19 pandemic.

Materials and Methods. A cross-sectional study was conducted using a short online questionnaire that was sent to primary care physicians in Bosnia and Herzegovina from April 20th, 2022, to May 20th, 2022.

Results. The research sample consisted of 231 doctors of primary health care from Bosnia and Herzegovina, with an average age of 45 years and 85% women. About 70% of participants reported having COVID-19 at least once from March 2020 to March 2022. Participants had an average of 1,986 registered patients and approximately 50 encounters per day. The study revealed a high degree of reliability between test-retest measurements, with a single measure Intraclass correlation coefficient of 0.801, and internal consistency determined using Cronbach’s alpha of 0.89. Participants reported that the following health services were most affected during the COVID-19 pandemic: care for patients with chronic diseases, home visits, navigating the health system with patients making appointments with specialists, cancer screening, and preventive health services. The study also found statistically significant perceived differences in the use of these health services based on age, gender, postgraduate education in family medicine, participation in COVID-19 clinics, and personal history of Covid-19.

Conclusion. There were significant disturbances to the use of primary health care during the COVID-19 pandemic. Future research could investigate patient outcomes compared to family physician perceptions.

Published: June 2023

Objective: Polycystic ovary (PCO), a diagnostic component of polycystic ovary syndrome (PCOS), requires either an ovarian volume (OV) criterion or a follicle number per ovary (FNPO) criterion. This study investigated the association of OV and FNPO criteria with various manifestations of PCOS. Methods: This cross-sectional study was conducted at a university hospital among 100 patients newly diagnosed with PCOS (according to the revised Rotterdam criteria). Fasting blood samples were collected to measure glucose, total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), lipid, insulin, and hemoglobin A1c levels. An oral glucose tolerance test was performed. Transabdominal or transvaginal ultrasound of the ovaries was done, depending on patients’ marital status. All investigations were conducted in the follicular phase of the menstrual cycle. OV >10 mL and/or FNPO ≥12 indicated PCO. A homeostasis model assessment of insulin resistance (IR) value ≥2.6 indicated IR, and metabolic syndrome (MS) was defined according to the international harmonization criteria. Results: Seventy-six participants fulfilled the OV criterion, 70 fulfilled the FNPO criterion, and 89 overall had PCO. Both maximum OV and mean OV had a significant correlation with TT levels (r=0.239, p=0.017 and r=0.280, p=0.005, respectively) and the LH/FSH ratio (r=0.212, p=0.034 and r=0.200, p=0.047, respectively). Mean OV also had a significant correlation with fasting insulin levels (r=0.210, p=0.036). Multivariate binary logistic regression analysis showed that IR (odds ratio [OR], 9.429; 95% confidence interval [CI], 1.701 to 52.271; p=0.010) and MS (OR, 7.952; 95% CI, 1.821 to 34.731; p=0.006) had significant predictive associations with OV alone, even after adjustment for age and body mass index. Conclusion: OV may be more closely related to the androgenic and metabolic characteristics of PCOS than FNPO.
Column Watch: Methods for the Passivation of HPLC Instruments and Columns

Published: June 2023

Metal-analyte interaction is a type of nonspecific adsorption (NSA) that occurs mainly between acidic analytes and active adsorptive sites present in the metal surfaces of the fluidic path of any chromatographic system. NSA represents a chromatographic challenge since it may lead to poor peak shape, low recovery, and poor performance from the high performance liquid chromatography (HPLC) system. As a result, many solutions that circumvent and mitigate this type of secondary interaction have been published or commercialized in the last few years. Such solutions encompass swapping stainless steel components for non-reactive polymers, “biocompatible” metals or alloys, the addition of additives into the mobile phase, pretreating the system with large amounts of sample or strong acids, and the use of coated stainless steel materials. This article explores these solutions in more detail, particularly the recent adaptation and benefits of coated metal surfaces in LC.
Öröklött hátrányok : Visszatérő és megújuló konfliktusok a Sellyei járás „felzárkózó” településein
Authors: Ragadics Tamás
Published: June 2023

Magyarországon a gazdasági központoktól távol fekvő, aprófalvas vidéki térségekben az egymással összekapcsolódó társadalmi problémák évtizedek óta képeznek megoldatlan, mélyülő válsághelyzetet. A leghátrányosabb helyzetben lévő falvak lakóit támogató Felzárkózó települések program sajátos jellemzője a lokális perspektíva érvényesítése, a helyi szükségletekre reagáló, diagnózisalapú beavatkozás. Jelen írás ezt a szemléletet erősíti. A tanulmány helytörténeti dokumentumok, a szocializmus utolsó évtizedeiben íródott falu- krónikák segítségével mutatja be azokat a kulcsfontosságú folyamatokat, amelyek ma is meghatározzák a Sellyei járás leszakadó, „felzárkózó” településeinek életét. A falusi élettér kiüresedése, a falu funkciótlanná válása, a közösségek válsága és hiánya, illetve az etnikai szegregáció problémaköre egyre markánsabban jelenik meg az éves szintű beszámolók anyagában, megelőlegezve, kezdeti fázisában bemutatva a jelenlegi válsághelyzetet.
A Hős utca felszámolásának sokadik kísérlete : Esettanulmány
Authors: Mihály Bulcsú

A hírhedt Hős utcai telep felszámolásában segédkezet nyújtó karitatív szervezetek, a Magyar Máltai Szeretetszolgálat, illetve az MR Közösségi Lakásalap és a terepen évek óta önkéntesen működő civilek közös munkája egy éve kezdődött. Nagyjából ötven lakos elhelyezésére (húsz tulajdonos kivásárlására) teszünk/tettünk kísérletet, amire annak ellenére kell hogy sor kerüljön, hogy az önkormányzat a Belügyminisztérium 2,1 milliárd forintos támogatásával már megpróbálta felszámolni a szegregátumot (láthatóan sikertelenül). Miért volt szükség az állami dotációval és az erősnek mondott helyi szociális intézményrendszerrel együtt is egy karitatív egyesület beavatkozására, a civilek jelenlétére? Az eset kapcsán számos dilemma felmerül: Képes-e az MRKL az emberi méltóságon alapuló és egyszerre szakszerű válaszokat kínálni a lakhatási válság bizonyos szegmenseiben? Lehetséges-e együttműködés önkéntes civilek (ha tetszik, „aktivisták”) és az első állami, de igazából mégsem állami szociális lakásügynökség között?

TOPSIS evaluation method is the abbreviation of Technique for Order Preference by Similarity to Ideal Solution. It is a multi-criteria evaluation method developed by Yoon and Hwang (1981). This method can be used in n project A ={Ai│i=1,2,…,n}, and evaluate under m evaluation criteria C={Cj│j=1,2,…,m}. And the performance value of the Ai project in the Cj criterion can be measured in a quantitative way, so that an evaluation matrix can be constructed to determine the best plan selection. This article uses the TOPSIS method to explore the corporate competitiveness of Taiwan's financial holding companies, and objectively evaluates the order of operating performance of each financial holding company. According to the evaluation indicators selected for financial holding companies in this article, it is found that the top 5 financial holding companies for performance evaluation are China National Bills Financial Holdings (2889), Cathay Pacific Financial Holdings (2882), Fubon Financial Holdings (2881), CITIC Financial Holding (2891) and Development Financial Holding (2883), the results can be used as a reference for the financial industry's operating performance evaluation.
Cross Fire: BTK Inhibitors Alone or in Combination are the Best Frontline Therapy for CLL
Authors: Sottero Theo , Awan Farrukh T.
Published: June 2023

BTK (Bruton's tyrosine kinase) inhibitors are highly effective front-line therapy for CLL (chronic lymphocytic leukemia) due to high response rates and prolonged progression-free survival, even in patients with high-risk disease features. They are also generally well tolerated, with the newer BTK inhibitors demonstrating better tolerability than ibrutinib while maintaining efficacy. Adverse effects such as bleeding or infections are usually manageable with supportive care or dose adjustments. Orally administered BTK inhibitors do not require intensive or inpatient monitoring and improve quality-of-life outcomes. Moreover, the established activity of venetoclax in the setting of BTK inhibitor failure is also reassuring as a salvage option. Nevertheless, the advantage of venetoclax as a time-limited treatment option is substantial, despite its inferior progression-free survival, since these patients can get another challenge with a reasonable chance of success. BTK inhibitors after venetoclax may be effective, but long-term data is limited. Given these reasons, BTK inhibitors remain the preferred treatment option as initial therapy for patients with CLL, especially those with del17p or TP53 mutations.

Published: June 2023

Background and objectives:

Allogeneic stem cell transplantation (Allo-SCT) in elderly patients is a growing practice. We aimed to determine the graft-versus-host disease (GVHD) relapse-free survival (GRFS) in patients ≥65 years who underwent Allo-SCT in two countries from Latin America.

Patients and methods:

We performed a retrospective analysis of patients ≥65 years who underwent Allo-SCT in Argentina and Brazil from 2007 to 2019.

Results:

Ninety-eight patients were evaluated, with primary diagnoses of acute myeloid leukemia and myelodysplastic syndrome; 30% of patients had a hematopoietic cell transplant-comorbidity index (HCT-CI) score ≥3 and 49% were in complete remission. Donor types included matched sibling (n = 41), matched unrelated (n = 31), and haploidentical (HID; n = 26) donors. The conditioning regimen was myeloablative in 28 patients (14 busulfan pharmacokinetically [PK]-guided) and reduced-intensity in 70 patients.

The two-year non-relapse mortality (NRM) was 29%, with a higher NRM in melphalan-based compared to other conditionings (51% vs. 33%, p = 0.02). The two-year relapse rate was 24%, with a reduction in PK-guided busulfan (0% vs. 28%, p = 0.03). The two-year overall survival (OS) and GRFS was 52% and 38%, respectively, with a significant reduction in GRFS in HCT-CI ≥3 (27% vs. others 42%, p = 0.02) and donors ≥40 years (29% vs. <40 years 55%, p = 0.02). These variables remained significantly associated with GRFS after multivariate analysis.

Conclusion:

In this cohort of elderly patients from Argentina and Brazil undergoing Allo-SCT, donor age and comorbidities significantly influenced GRFS. The role of the conditioning regimen in this population deserves further investigation.
Prognostische Propheten

Zahlen, Daten und statistische Kurven bestimmten den Coronadiskurs. Die sich daraus ergebenden wissenschaftlichen Modellierungen formten den prognostischen Blick, der weitreichende gesellschaftspolitische Entscheidungen beeinflusste. Robert Niemann identifiziert hier einen neuartigen wissenschaftlichen Subjekttypen, den prognostischen Propheten. Er weist den Menschen den Weg durch die Katastrophe und ist in diesem Sinne nicht nur populärwissenschaftlicher Vermittler sondern eine machtvolle Form subtiler Menschenführung. Diese neuartige Form einer rhetorischen Führungstechnik ist möglicherweise eine Folie für die Führung in kommenden Katastrophen.
Freiheit von Wissenschaft
Authors: Bachhiesl Christian
Published: June 2023

Die Wissenschaft als Leitinstanz der Wissensgesellschaft verspricht Fortschritt, Wohlstand und die Befreiung des Menschen, die weitestgehende individuelle Autonomie – wenn man ihr nur selbst ausreichend Freiheit gewährt. Doch das Dogma von der Wissenschaft als Heilsbringerin ist brüchig geworden. In seinem Essay zeigt Christian Bachhiesl negative Auswirkungen dieses Wechselverhältnisses auf: Was die Wissenschaft und im Verbund mit ihr die Technik uns an Fortschritt auch bringen, es wird neue Abhängigkeiten, normative Imperative und die Kontrolle von immer mehr Lebensvollzügen geben. Kaum ein Bereich unseres alltäglichen Lebens bleibt vom Einfluss der Wissenschaft verschont. Der Exzess des Wissens führt dabei notwendigerweise zu einem Verlust an Vertrauen und Glauben. Aus dieser Perspektive bedroht die Freiheit der Wissenschaft die Freiheit des Menschen, der auf eine bloß materialisierte und quantifizierte Entität reduziert wird. Um ein sinnerfülltes Leben führen zu können, so der Autor, bedarf es dagegen der epistemischen Bescheidenheit und der »Empfindsamkeit als epistemische Tugend«. Er plädiert dafür, auf unserem Weg der Erkenntnissuche, der »von der Weisheit zur Wissenschaft« geführt hat, umzukehren und uns wieder dem Streben nach Weisheit zu öffnen. Über die Freiheit von Wissenschaft muss neu nachgedacht werden, wenn es um die Freiheit des Menschen geht.

Bu araştırmanın amacı uluslararası ölçekte havayolu yolcu taşımacılığı şirketlerinin varlık ve finansal yapılarının karşılaştırmalı analizidir. Bu kapsamda Amerika Birleşik Devletleri, Asya-Pasifik ve Avrupa ülkelerindeki 64 havayolu yolcu taşımacılığı şirketinin 2016-2021 yılları arasındaki finansal durum tablolarına yapısal dikey yüzde analizi uygulanarak varlık ve finansal yapısı incelenmiştir. Yapısal analizde dönen ve duran varlıkların varlık toplamı, kısa ve uzun vadeli borç ile öz kaynakların ise finansal kaynak toplamı içindeki yüzdelik payları analiz döneminde hesaplanmış ve hem şirket bazında hem de örneklem temelinde ortalamaları alınarak karşılaştırmalı olarak incelenmiştir. Ayrıca şirketlerin varlık ve finansal yapı alt ana grupları arasındaki ilişki korelasyon analiziyle belirlenmeye çalışılmıştır. Araştırma sonucunda havayolu şirketlerinin genel olarak sabit varlık ağırlıklı olduğu, finansal yapısının ise daha çok uzun vadeli olmak üzere yabancı kaynak ağırlıklı olduğu, buna karşın öz kaynaklarının yetersiz kaldığı ve bu bağlamda finansal riskin çok yüksek olduğu saptanmıştır. Bununla birlikte COVID-19 salgınının genel olarak şirketlerin sabit varlık yatırım seviyelerini azalttığı dönen varlıkların payını ise yükselttiği belirlenmiştir. Ayrıca bütün örneklemlerde 2020 yılında öz kaynak paylarının ortalama da önceki yıllara göre en düşük seviyede gerçekleştiği ve finansal risk düzeylerinin daha da yükseldiği belirlenmiştir.

Authors: Bourne Shawna , Kothari Anita , Wathen Nadine , Polzer Jessica
Published: June 2023

Background

The purpose of this study was to explore the dimensional structure of the Environmental Health Officer (EHO) responses to the BARRIERS Scale from data collected in 2012 and 2020 to: (1) uncover new holistic ways of interpreting the factors influencing research utilization (RU); and (2) apply a theoretical lens to the data.

Methods

Principal Component Analysis was used to analyze the dimensional structure of the 2012 data and develop a structural equation model (SEM). The resultant factors were categorized using the Active Implementation Frameworks (AIFs). Confirmatory Factor Analysis was applied to the SEM using the 2020 data.

Results

A four factor solution was identified and the resultant SEM aligned with the following AIFs: Competency Drivers, Useful Innovations, Leadership Drivers, and Organization Drivers. The SEM was found to explain 52% of the loading variation, capturing a satisfactory amount of information from the dataset. The SEM was analyzed for goodness of fit using 2020 data and it showed a statistically sound but imperfect fit.

Conclusions

These four factors provide a useful way to understand and mitigate barriers to RU in EHO practice. Three of the factors align with the Implementation Drivers Framework (Competency Drivers, Leadership Drivers, and Organization Drivers) and the fourth factor was associated with the Useful Innovations Framework, representing only two of the six AIFs, thus demonstrating a theoretical gap. The imperfect goodness of fit test indicated a statistical gap. These results suggest that more research is needed to better understand the full set of barriers to RU experienced by EHOs.
Measuring the Impact of COVID-19 on Attitudes towards SOPs: A Study of Smart Lockdown across Generations in Pakistan
Authors: Mobashira Alvi  , Nadeem Ehsan
Published: June 2023

Countries all across the world are struggling to prevent a pandemic caused by a novel coronavirus called COVID-19. However, for a country like Pakistan, which already faces challenges such as an economic shutdown, a shortage of healthcare financing, and prevalent false beliefs, the only known approach to stop the spread of COVID-19 is through prevention and social isolation. Since public awareness of COVID-19 is essential to its containment, a survey was designed to assess its people's level of information and attitudes towards SOPs and smart lockdown across generations during COVID-19. The general population of Pakistan was asked to fill out an online questionnaire that has been pre-validated. SPSS v18 was used for the statistical analysis of descriptive data. Scores of > 4 (range: 0-8) were given for adequate knowledge, and scores of > 3 (range: 0-5) were given for good perception. To determine what elements contribute to having sufficient understanding, a logistic regression analysis was conducted. There was a wide diversity of ages and levels of education among the 102 people from selected three generations who filled out the survey. The majority of respondents had good perceptions and a sufficient level of knowledge. Gender, age, education, income and occupation of the participants, all showed statistically significant variations in knowledge and perception. Multivariate analysis revealed that higher levels of education and female were significant predictors of sufficient knowledge regarding the disease and perception. Thus, adherence to preventative protocols and accurate information dissemination depends on the success of educational activities that emphasize the cure of the disease and relevant evidence about the disease.

Published: June 2023

The existing systems normally used to monitor the industrial environmental condition in factories in Kenya are mostly wired systems and more expensive. Despite the benefits of tools and emerging technology, most companies do not use automated systems due to the high installation and maintenance costs and a lack of formal early-warning mechanism. This research project intends to provide information using wireless sensor technology, which comprises of sensors, Zigbee, raspberry pi, Arduino Uno, and wireless sensor network (WSN). The system is developed using open-source hardware raspberry pi and Zigbee which proves to be cost-effective and has low power consumption. The sensors will collect the data of various environmental parameters and transmit it to the raspberry pi, which acts as a base station. The raspberry pi will then transmit the data using Zigbee, and the processed data displayed on GUI through the Zigbee on the receiver end. The database was developed using MYSQL DB and the web application written in the PHP programming language. In addidtion, the system is integrated with Zigbee technology to send SMS and e-mail notifications to the respective registered users. The developed system was tested at different plant areas to detect the concentration of Carbon monoxide, temperature, humidity, and dust in the factory. The result shows that the system responds positively when these parameters were detected and sends notification alerts via e-mail and SMS. Finally, the data collected can be used for further data analysis and research in the future.

Published: June 2023

The Prosopis julifrola plant is a thorny leguminous shrub or small tree, a kind of mesquite in a family of Fabacea. It is extremely aggressive and invasive. The spreading agents include livestock dispersal and seeds in their droppings, human activity by vegetation restoration, firewood and charcoal and soil erosion control. In this study a deterministic model examines the dynamics of Prosopis juliflora plant by adopting a similar approach of a dynamical system as used in epidemiological modeling. The local and global stability analyses of the equilibrium points of the model were conducted by using next generation matrix for the computation of basic reproduction number R0 and Lypunov function. The study showed that the Prosopis juliflora plant free equilibrium of the model is both locally and globally asymptotically stable if and only if the number of secondary infections is less than unity, that is if R0 < 1. Furthermore, the study shows that there exists Prosopis juliflora endemic equilibrium for the spread of the plant when R0> 1. The numerical simulation was implemented in MATLAB ODE 45 algorithm for solving linear ordinary differential equations. The study showed that the plant spread with an increase of animals that ingested it. Based on the study, recommended is the application of the model on the endemic area to improve the existing situation through: Enlightening and involving policymakers, environmentalists, stakeholders and community groups in the preservation framework on the spread and control strategy of the Prosopis juliflora invasion
A predictive model for early detection of diabetes mellitus using machine learning
Authors:   , Semakula Henry
Published: June 2023

Diabetes is a chronic, metabolic disease characterized by elevated levels of blood glucose or blood sugar that over time can bring severe damage to vital organs including the heart, blood vessels, eyes, kidneys and nerves. Diabetes is therefore one of the major priorities in medical science research. Type 2 diabetes is common in adults, either because of inadequate insulin production, or when the body’s cells fail to respond properly to the produced insulin. For all the diabetes cases, it’s found out that 90% are Type 2 diabetes. Of the 422 million people with diabetes worldwide, 336 million people are found in developing countries, and 1.6 million people die of diabetes each year according to statistics by the World Health Organization. Around 19.8 million adults in Africa have Type 2 diabetes but approximately 75% are unaware of their condition (undiagnosed). Most people are undiagnosed because many people lack knowledge of symptoms for diabetes, and others are not diagnosed due to lack of testing kits more especially in rural areas. African governments have scaled up purchasing and distribution of diagnostic kits but the majority of the population has not been reached. Researchers have been developing predictive models for Type 2 diabetes, but African populations are not widely included in their datasets. The developed models may therefore not accurately identify at-risk populations in the African context. The main emphasis of this research was to come up with a machine learning prediction model to find out Ugandans likely to be suffering from Type 2 diabetes (output classes: high risk or low risk), based on input symptoms. Random Forest, Support Vector Machine, Naïve Bayes, and AdaBoost classifiers were trained on anonymised, real patient data with twelve features including age, gender (male or female), systolic blood pressure, residence (town or village), diastolic blood pressure, family Member with diabetes, alcohol intake, smoker, hypertensive, obesity, physically inactive and body mass index. This research’s experimental results after the comparison of the Accuracy Score and Confusion Matrix for all the above algorithms, the Random Forest classifier emerged the premier with the accuracy score of 85.4%, thus the experimental results shown that performance of Random Forest classifier as being significant superior compared to all other the machine learning algorithms.
A quantification model against tuta absoluta effects on tomato plants: a computer vision approach
Authors:   , Loyani Loyani
Published: June 2023

Tomatoes are among the most commonly cultivated crops in the world. It is considered a high value crop and income resource for smallholder farmers in Africa. Nevertheless, its production currently endangered by Tuta absoluta pest. The pest has severely damaged tomato yields to the extent that growers are giving up tomato production due to the high costs and losses incurred. It causes a heavy loss in tomato produce ranging from 80 to 100% when not effectively managed. Recently, farmers have been using different methods in efforts to control the pest. These include using pheromone traps and natural enemies for population monitoring, planting resistant tomato varieties, and continuous spraying of chemical pesticides, which is now the main control method. These practices have been proven not to be effective in controlling the pest; they are time-consuming and relatively expensive. Inspired by the progression and positive outcomes of computer vision methods in diagnosing a wide variety of plant diseases and pests, this study proposes a segmentation-based quantification model for detecting and quantifying Tuta absoluta’s damage to tomato plants. We develop convolutional neural network models based on U-Net and Mask RCNN architectures for automatic semantic and instance segmentation respectively using data collected from the field. Experimental results show that Mask RCNN achieved a mAP of 85.67% and U-Net obtained 78.60% and 82.86% of Jaccard index and Dice Coefficient respectively. Both models were precise in segmenting the shapes of Tuta absoluta-infected areas in tomato leaves and determine their extent of the damage. The model was then deployed on the mobile phone to enable farmers and extension officers in Tanzania to automatically detect affected areas on tomato plants and make informed decisions on how to control the pest so as to increase tomato production and save farmers from the losses they face.

Efforts to reduce stunting require nutrition interventions that are carried out in an integrated and integrated manner, including specific and sensitive nutrition interventions. Specific interventions include providing balanced nutritional staple food to stunting toddlers. The sample in this study were 30 stunted toddlers in the Simpang Periuk Health Center working area with the type of intervention, namely providing balanced nutritional staple food for 90 days. The method used in this study uses an experimental design with a pre and post-test approach without control. The statistical test used was the paired sample test by comparing the nutritional status of toddlers before and after intervention. This research was completed in December 2022. The results showed a p-value of 0.000 (<.05), indicating that there was a significant difference in toddler height before and after the intervention was given, so it can also be concluded that the provision of balanced nutritious staple food interventions for 90 days can increase the height of toddlers thereby reducing the stunting rate in the target toddlers.

Bu araştırmanın amacı bir kamu kuruluşu olan TÜVASAŞ içerisinde hesap verebilirlik ve örgütsel adalet ilişkisinin ne düzeyde olduğunu tespit etmek ve değerlendirmektir.
Araştırmanın birinci bölümünde hesap verebilirlik kavramı üzerinde durulmuş, ikinci bölümde ise örgütsel adalet kavramı üzerinde durulmuştur. Üçüncü ve son bölümde ise araştırma verileri ve sonuçları üzerinde durulmuştur. Bu araştırmada veri toplama aracı olarak Diğdem Doğan (2015) tarafından geliştirilen ve geçerliliği ve güvenilirliği test edilmiş olan “Yükseköğretim Kurumlarında Hesap Verebilirlik Ölçeği” nin kamu kurumu çalışanlarına yönelik uyarlaması yapılarak kullanılmıştır. Örgütsel adaleti ölçmek amacıyla Nieoff ve Moorman (1993) tarafından geliştirilen “Örgütsel Adalet Ölçeğinin (Justice Scale)” Fatma Yıldırım (2007) tarafından uyarlanan Türkçe formundan yararlanılmıştır. Araştırmada tarama modellerinden ilişkisel bir tarama modeli benimsenmiştir. Araştırmanın evreni TÜVASAŞ’ta çalışan 1103 kişiden oluşmakta ve araştırmamızın örneklemi ise kolayda örneklem yöntemi ile seçilen 337 kişiden oluşmaktadır. Elde edilen verilerin analizi için SPSS 20.0 paket programından yararlanılmıştır. Veriler korelasyon analizi ve regresyon analizi yöntemleri ile analiz edilmiş ve araştırma sonuçlarına göre hesap verebilirlik ve örgütsel adalet arasında pozitif yönlü ve istatistiki açıdan anlamlı bir ilişkinin olduğu saptanmıştır. Ayrıca hesap verebilirliğin, örgütsel adalet üzerindeki etkisi incelendiğinde istatistiki açıdan anlamlı olduğu ve hesap verebilirliğin örgütsel adaleti açıklama düzeyinin %50’nin üzerinde olduğu sonucuna ulaşılmıştır.
Bu araştırmanın sonuçları, söz konusu kamu kurumundaki hesap verebilirliğin ve adalet algısının bilimsel yollarla tespit edilerek mevcut olan olumsuz algıların giderilmesi için uygun çözüm yolları ve önerilerin oluşturulması açısından önem arz etmektedir.
