Socialist in content, national in form: Small-scale housing estates in Budapest between 1945 and 1960
Authors: Bene Bence
Published: June 2024

In the second half of the 20th century, solving the housing crisis became a significant social issue and political task throughout Europe, particularly in the countries of the Eastern Bloc. Although due to its quantity, prefabricated large mass housing estates became overrepresented, dozens of smaller, experimental, and diverse mass housing forms also emerged. It is hypothesized, that these small housing estates, due to their scale and quality, are urban planning projects that were realized across political, economic, and architectural changes. To demonstrate their adaptability, this paper presents the small housing estates built in one of the capitals of the Eastern Bloc countries—Budapest—during the most turbulent one-and-a-half decades of the socialist era (1945–1960). The research consists of three main parts: (1) Hungarian politics and housing policy, (2) Budapest's urban policy, and (3) a brief presentation of the urban planning and architectural aspects of Budapest's small housing estates. The result of the research is the creation of a complete small housing estates portfolio, illustrated archive articles, archival plans, and photographs. It becomes evident that although the times from World War II to the consolidation of power saw vastly different political eras, directives, and ideals realized, along with various architectural styles and housing policies, the small housing estate as an urban planning product was able to adapt and survive. Moreover, it is a valuable architectural, housing, and urban planning imprint of the era, the only mass housing form realized in numerous examples in Budapest.
Enhancing visual comfort in staircases: A comprehensive analysis and design recommendations
Authors: Benkouda Hassina , Louafi Samira , Mebarki Ammar
Published: June 2024

People should be walking towards the inside of the dwelling through an appropriate visual environment in transitional space; this environment is the staircase in the collective housing. The proper understanding of visual adaptation parameters in the staircase helps architects provide a suitable environment for inhabitants. This paper aims to specify design elements of the staircase in collective housing, to achieve a visual comfort in this transitional space. The work involved two approaches: field measurements and a visual comfort survey using a questionnaire; 144 questionnaires are collected, in four residential buildings with different staircases treatment in the city of Arris, Algeria, to examine the illuminance levels in different staircase positions along the path from outside the building to inside, in summer and winter where illuminance ratios were calculated and compared with CIBSE Code. The discomfort sensations ranged from "subtle” to "dramatic”. The results show that a staircase with the percentage of opening of 88% indicated "strong" and "dramatic" visual shock in many points and as this staircase is open, it is exposed to light conditions and so it does not ensure the necessary transition. This leads to advising against the open staircase. In the case of a staircase treated with transoms of clear glass with the percentage of opening of 11%, these transoms direct the light to specific areas creating "strong" visual shock in many points of the stair landings and hence it leads to advise against that. The staircases treated with vertical bays throughout the façade presenting a percentage of opening between 19% and 22%, these treatments allow the penetration of daylight in a diffused way which ensures a balanced distribution of daylight inside the staircases. The existence of a solid overhang at the entrance; the façade treated with vertical bays, where the percentage of opening of the façade is about 19% and 22%, provided adequate transition leading to reasonable visual comfort.
Gamification Solution in Teacher Education
Authors: Buda András , Pesti Csilla
Published: June 2024

Introduction:

Achievements of students in higher education are influenced by several factors. From the students’ perspective a key factor is the motivation, without which it is extremely difficult to make any progress, and from the teachers’ perspective the conservative methodological culture is primarily responsible for the fact that students are often uninterested, apathetic, and therefore they do not meet the expected requirements at all or only at a low level.

Methods:

In a pilot project we gamified the evaluation of a teacher education course at the University of Debrecen. We asked the participating students (26 students) at the beginning and at the end of the semester for their opinion on the evaluation system used. For this purpose, we used a short questionnaire that we compiled, which included both closed and open questions.

Results:

At the beginning of the semester, this form of assessment was very new to most students, and the difficulty of the assessment was judged differently by the course participants. In the end, students completed an average of nearly 5 (4.67) of the nine optional tasks. There were some tasks that were rated as both enjoyable and developmental by many, but there were also some that were barely chosen. Overall, the vast majority rated gamification as good or better than traditional assessment based on completion of compulsory tasks.

Discussion:

Gamification should be included in teacher education courses because first-hand experience can not only increase the intention to use the method in the future but can also influence the attitude of prospective teachers towards innovative teaching methods in a positive direction.

Limitations:

The size of the sample and the content of the optional tasks used do not allow the generalisation of the results to the whole population.

Conclusions:

Our results show that gamification can be an effective alternative to traditional education. It can increase student satisfaction, motivation and develop a broader range of competences, but it requires precise conditions and ownership. It would be useful to investigate the results of gamification assessment in other courses and how students' perceptions of the method change in courses where they are no longer unfamiliar with it.
Constraints, Contradictions and Challenges regarding Cooperation of Parents during COVID-19: A Social Capital Perspective
Authors: Motsumi Tshegofatso Portia , Khumalo Shuti Steph
Published: June 2024

Introduction:

When calamity hits humanity in the form of natural disasters, they appear unannounced. The same applies to the recent destructive and disruptive Covid-19 pandemic. During the early days of this pandemic, life activities were halted abruptly. Global education systems were not spared - most institutions were caught napping and forced to close. The educational development of children was adversely affected by the hard lockdown and stringent restrictions that followed the outbreak of the pandemic. The role that parents had to play in the education of their children needed to evolve to meet the new demands.

Methods:

The researchers approached this study from a qualitative interpretivist philosophical stance to interview principals, teachers, and parents. In addition, this paper was located within Coleman’s social capital theory.

Results:

Amongst the key findings that emerged from the study were serious challenges regarding parents’ cooperation during the Covid-19 pandemic, namely, communication challenges between the school and home, increased learner absenteeism, and failure by learners to do schoolwork. Finally, the study also found that some parents were disinterested and disengaged from the schools. This study is significant because it provides epistemological insights and understanding of the challenges schools experienced during the Covid-19 pandemic.

Discussion:

Without exception, all participants felt strongly that the involvement of parents in a child’s education during a pandemic such as Covid-19 is significant. According to Durisic and Bunijevac (2017), the more actively parents are involved in their children's learning, the more benefits are achieved. In contrast, there often seems to be little to no collaboration between the school and the home in ensuring that their common goal of seeing the child succeed is achieved. This is in harmony with the findings of Porumbu and Necsoi (2013) who intimate that, sometimes, parents may feel like they are doing everything to help their children, but due to lack of communication between the parents and the school, the school may feel as though involvement is lacking.

Limitations:

The study was limited to only three schools and only nine participants were subjected to semi-structured interviews.

Conclusions:

The study provided epistemological insights regarding the cooperation and involvement of parents during the trying circumstances of the Covid-19 pandemic. This study provided the findings which are critical for theory, practice and policy to the education systems regarding future disasters.
Soil drought stress and high-temperature effects on photosystem II in different juvenile spruce provenances
Authors: Jamnická Gabriela , Húdoková Hana , Fleischer Peter , Ježík Marek
Published: June 2024

With prolonged periods of drought and temperature extremes becoming more frequent, the stress on Norway spruce has increased, as its ecological optimum is in colder and more humid environments. However, it is a tree species with a good adaptability, due to its great geographic and intraspecific variability. In this study, we tested the sensitivity of chlorophyll a fluorescence tools for the early detection of drought and heat stress, as well as their combined effect, in four Slovak Carpathian provenances, under controlled laboratory conditions. Responses in photosynthetic parameters of fast and slow (light response curves) kinetics of chlorophyll a fluorescence were analysed in spruce seedlings under four treatments: control, drought, heat, and combined drought + heat. Heat and drought + heat stresses led to the decrease of photosynthetic efficiency to a greater extent than in the case of only individual drought stress. The less sensitive parameter impacted by the stresses was the maximum quantum yield of PSII photochemistry (Fv/Fm), while the more sensitive parameters were: the performance index based on absorption of light energy (PIABS), the effective quantum yield of the PSII (ΦPSII), and the coefficients of non-photochemical fluorescence quenching (NPQ, qN). The significant variability in responses of individual provenances was also observed. Seedlings from two studied provenances responded better to these abiotic stresses (Pa-680 and Pa-1500); however, Pa-1500 provenance from the highest altitude showed the best ability of resistance to soil drought stress, as well as to high temperature effect. This rapid screening of photosystems II efficiency showed the importance of the selection of more resistant populations to concurrent stresses as one of the measures to mitigate climate change impacts.
Drought effects on growth, biochemical changes and leaf gas exchange in laurel (Laurus nobilis L.)
Authors: Ishimwe Christine , Deligöz Ayşe
Published: June 2024

Drought is one of the abiotic factors that negatively affect the productivity of laurel (Laurus nobilis L.). Increasing water scarcity in arid and semi-arid regions is pushing the physiological limits of woody species, necessitating strong resistance to drought. Studies should be conducted on the effects of drought stress not only on forest trees but also some medicinal and ornamental species, and ways to increase their resistance should be explored. This study was carried out to determine the effect of drought stress on seedling growth and some physiological and biochemical properties in laurel. The seedlings were subjected to drought stress for about 4 months with three different irrigation regimes: watering once every 2–3 days (control), every 15 days, and every 30 days. Morphological properties (root collar diameter, height, dry weight, stem: root ratio, and number of leaves), physiological properties (midday xylem water potential and photosynthesis properties), and biochemical properties (photosynthetic pigments, total carbohydrate, and proline contents) were determined. Results have shown that drought stress has a negative effect on root collar diameter, seedling height, and dry weight. Likewise, leaf number and midday xylem water potential decreased due to increased drought stress. Furthermore, the net photosynthesis rate, stomatal conductance, and transpiration rate of the least irrigated (30th day) seedlings were quite low compared to those of control seedlings. The differences in chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid contents were also found to be statistically significant. Total carbohydrate and proline contents showed the highest values for the least irrigated seedlings and the lowest values for controlled irrigation seedlings. Our results reflect the improved tolerance capacity of laurel to increased drought stress.
Sessile oak (Quercus petraea [Matt.] Liebl.) and its adaptation strategies in the context of global climate change: a review
Authors: Černý Jakub , Špulák Ondřej , Kománek Martin , Žižková Eliška , Sýkora Petr
Published: June 2024

This paper provides characteristic and a comprehensive overview of the adaptation strategies of sessile oak (Quercus petraea [Matt.] Liebl.) in the context of global climate change (GCC). The GCC is primarily manifested by increasing air temperatures and changing precipitation distribution. It poses a significant challenge to tree species including sessile oak, affecting its capacity for adaptation and survival. Despite the challenge, sessile oak shows significant drought tolerance due to its deep-reaching root system, which allows the tree to use available water more efficiently. Other adaptive strategies include the establishment of mixed stands that increase the resilience and biodiversity of the ecosystem. Adjustments of stand density through tending interventions play a significant role, helping to improve the stress resistance of stands. Additionally, coppice forest cultivation is applied on extremely dry sites. The sessile oak is also significant for its ecological plasticity – its ability to thrive on versatile soil and climatic conditions makes it a promising tree species for future forest management. Mixed stands with sessile oak and other tree species can enhance the ecosystem services of forests and also increase their endurance to GCC events. However, sessile oak faces several challenges, including the increasing risk of damage from pests and pathogens that require targeted measures for its protection and sustainable cultivation. The literature review suggests that a comprehensive understanding of sessile oak’s ecological requirements and interactions with the environment is crucial for its successful adaptation to GCC and the formulation of effective strategies for its protection and use in forest management.
Experimental Evaluation of Most Sustainable Companies: Impact on Economic Growth, Return on Equity (ROE) and Methodological Comparison
Authors: Serzante Milena , Stankevych Viktoriia
Published: June 2024

Research purpose.

The study aims to analyse, how the sustainable performance of the company impacts the economy and businesses' economic performance, and to build a model, using environmental, social, and financial indicators.

Design / Methodology / Approach.

To achieve this goal such methods as the Pearson correlation, Multiple Linear Regression, Cook's distance method, K-nearest neighbour and COPRAS technique were implemented.

Findings.

The results indicate no significant correlation between the sustainability activities of companies and the GDP of their respective countries, nor between companies' ROE and their sustainability performance. These findings suggest that conventional methods of evaluating corporate sustainability may not accurately reflect its economic impacts. Furthermore, discrepancies observed between the Corporate Knights rankings and those calculated using the COPRAS method highlight the critical need for a deeper examination of assessment methodologies. This outcome calls for a reassessment of sustainability practices and methodologies to better understand and leverage their benefits in the corporate and economic realms. While the study provides initial insights into the current sustainability assessments, further research should explore alternative evaluative models and their implications across different industries.

Originality / Value / Practical implications.

Companies have a significant impact on the environment and society, and sustainability is important not only for ethical concerns but also for financial and economic reasons.
Is the School a Learning Organization?
Authors: Matei Florentina Lavinia , Lincă Florentina Ionela
Published: June 2024

The concept of an organization that learns “learning organization” is one of the most mentioned ideas in management, representing a subject of great interest for theorists in the field and for those involved in the functioning of organizations. The actuality of the topic consists in the fact that today learning has an important role within organizations. Learning and teamwork are highly encouraged in order to achieve common goals and to achieve the results that the members of the organizations really want. In contemporary times, society is in a continuous process of change. Under these conditions, the school must develop its ability to change to the new in order to face the challenges so that its role as a factor in the development of society becomes more and more obvious. Thus, permanent learning appeared as a reaction to the rapid transformations taking place in society, representing at the same time a necessity and a solution. The school is part of the category of organizations that learn, it being different from the others due to the specificity of the dominant activity, namely the instructive-educational process. In this article, we addressed the main characteristics existing in the specialized literature that define the learning organization, the school as a learning organization, as well as the identification of the existence of a possible relationship between the personal factors of teachers and the strategies that make the school a learning organization. The results illustrate the necesity of a correlation factors, such as function, teaching degree, seniority at work, with the strategies that make the school a learning organisation. In the table below we can see that the education level of the teaching staff is the only variable that does not correlate with the strategies that make a school a learning organisation.
The Impact of the Montessori Education on Pupils Diagnosed with ADHD: the Analysis of the Perceived Level of Academic Performance, Behaviour, Reactivity, Self-Eficacity, and Social Integration by Reference to Traditional Education Programs
Authors: Eşi Marius-Costel
Published: June 2024

The research investigates the impact that Montessori alternative education programs have on alleviating the effects of the ADHD symptomatology in the classroom and globally.As a cross-sectional study aimed at the comparative analysis of the academic performance, behavior, reactivity, self-efficacy and social integration, the research intends to provide a deep understanding of how this pedagogical method can contribute to the academic and social development of these pupils, while emphasizing their specific needs. The detailed analysis of the results brings to light the practical implications and the theoretical implications of using the Montessori method in the context of education for children with ADHD nationwide. Data were collected from a group of parents (N=104) who have children enrolled in eithe Montessori or traditional education programs and the analysis was aimed at assessing the significant differences between the two groups, as they were perceived by the respondents.

The overall results indicated that in the Montessori reference classroom, parents reported children’s better academic performance, a satisfactory classroom behavior, positive social interactions and greater overall improvement compared to respondents associated with the traditional type of educational program. However, no significant differences were identified in terms of emotional self-regulation and reported self-efficacy between the two types of programs. The interpretation of these results suggests that the Montessori programs can provide a beneficial educational environment for the children’s global development, improving important matters of their school and social life.
Social Life Influences on the Academic Success of Neurodiverse University Students
Authors: Shoko Ratidzai
Published: June 2024

University academic success is influenced by a number of variables. One of the factors influencing both neurotypical and neurodiverse students’ academic success at university is their social life. Students that are neurodiverse, however, also face additional challenges in maneuvering through their social life in comparison with neurotypical students. This paper argues that academic success for neurodiverse individuals is significantly influenced by their experiences in university social life. The social model of disability is the theoretical framework used in this article to examine and understand the relationship between the experiences in the social life of neurodiverse university students and their academic success. This paper argues that to increase the level of support provided to neurodiverse students, all stakeholders must work together.
Equity in the classroom

Published: June 2024

The theme of equity in the classroom is particularly relevant and necessary in the current context of education. The choice of this theme is motivated by several important factors that underline the need for a systematic and rigorous approach in the study of educational equity.

Equity in education represents a fundamental pillar for sustainable social and economic development. In a constantly changing society, where ethnic, cultural, and socio-economic diversity is increasingly pronounced, ensuring equitable access to quality education for all students becomes extremely necessary. The study of equity in the classroom allows for the identification and addressing of inequalities that affect the educational success chances of students from different backgrounds. Conducting a dissertation on the theme of equity in the classroom will allow me to develop advanced research skills, critical thinking, and analytical competencies. These skills are essential for my career in the field of education and will enable me to significantly contribute to the development of more equitable educational policies and practices. Additionally, this research will facilitate collaboration with other professionals in the field of education, encouraging the exchange of ideas and experiences.

Introduction

The aim of the study was to monitor the occurrence of selected vector-borne diseases in anaemic dogs arriving in or returning to Poland from areas endemic for these diseases.

Material and Methods

The study involved 497 dogs, of which 184 came to Poland from Ukraine with their owners fleeing the war. Other animals returned to the country from holidays spent in Croatia (n = 96), Turkey (n = 79), Italy (n = 48), Bulgaria (n = 42), Albania (n = 36) and Romania (n = 12). Molecular biology methods were used for detection of pathogens transmitted by the vectors.

Results

Molecular tests revealed the presence of vector-borne pathogens in 79 dogs. The most commonly diagnosed infection was caused by Babesia canis (27 dogs), followed by infections with Anaplasma phagocytophilum (in 20 dogs), Mycoplasma haemocanis (15 dogs), Bartonella henselae (7 dogs), Ehrlichia canis (4 dogs), Hepatozoon canis (3 dogs), Babesia gibsoni (2 dogs) and Leishmania infantum (1 dog). Most of the sick dogs (n = 39) came from Ukraine. In dogs spending holidays with their owners outside Poland, vector-borne diseases were most often detected after their return from Turkey (n = 16), and next in descending order from Croatia (n = 7), Italy (n = 6), Albania (n = 4), Bulgaria (n = 4) and Romania (n = 3).

Conclusion

The wider migration crisis and increasingly frequent trips of owners with their dogs to areas of endemic infectious and parasitic diseases observed in recent years are the main risk factors for the occurrence of these diseases in Poland. Therefore, constant monitoring of vector-borne diseases, especially in dogs returning from holidays and arriving in Poland from abroad, seems to be crucial for their early detection and introduction of appropriate therapy.
PROCESSING AND CHARACTERIZATION OF OIL PALM LOOSE FRUITS AS A RAW MATERIAL FOR BIODIESEL

Published: June 2024

The main product of oil palm plantations is oil palm fresh fruit bunches, however there is oil palm loose fruits which is detached from the ripe fresh fruit bunch or found during the process of cutting at harvest. Biodiesel could be obtained by processing crude palm oil (CPO) with trans-esterification process, however CPO is an important source of food, especially for cooking oil. Biodiesel production as a source of new renewable energy increases, hence it could threat the food security programs. The oil palm loose fruits as an industrial waste were investigated for renewable energy sources to overcome the conflict between the renewable energy program and food security. This research found that oil palm loose fruits consisted about 55% of mesocarp (flesh of fruit) and around 45% of the seed. Increasing delay on processing of oil palm loose fruits led to decreasing of the oil, and processing delay for 12 days resulted in a significant reduction extract yield. Increasing processing delay reduced the iodine value and the study showed that oil palm loose fruits after 12 days have a high level of oil saturation and free fatty acid of CPO was 37%. Esterification followed by transesterification was conducted to synthesis biodiesel. The biodiesel was obtained with yield of 14.5%, and free fatty acid of 1.3%, while fatty acid methyl ester was achieved 70.24%. Hence, we could convert oil palm loose fruits into biodiesel as a strategy to meet the renewable energy requirement produced from non-food crops

Most of the swallowed foreign bodies pass through the gastrointenstinal tract (GIT) and only 1% of them are required surgery. Many authors have reported different cases of a foreign body migration deep into the layer of the gastrointestinal tract and their successful subsequent surgical treatment. However, there are some limited reports about the extraction of the embedded foreign bodies, when endoscopic techniques, such as endoscopic submucosal dissection, are used. We present the case of a 70-years old patient who was performed full-thickness resection of a duodenal neuroendocrine tumor. According to upper endoscopy, the submucosal gastric antral tumor was suspected. During the preoperative examination, esophagogastroduodenoscopy, endosonography and computed tomography were performed, but the nature of the formation was not determined. During the full-thickness resection, the embedded foreign body (a fish-bone) with the fistula around it was revealed and successfully extracted. This case demonstrates a rare pathological situation – the foreign body of the gastric wall, as well as the efficiency of flexible intraluminal endoscopy to extract it.

Published: June 2024

The formation of low colorectal and coloanal anastomoses after low anterior and abdominal-anal resection of the rectum has always been a significant problem in surgery. A loop protective ileostomy can reduce the consequences of anastomotic leakage, which reaches 23 %, and in some cases avoid repeated emergency surgery. However, ileostomy also has negative consequences, such as the need for repeated surgery to eliminate the ileostomy, parastomal complications, large stoma losses, and low quality of life. A virtual ileostomy or “ghost ileostomy” has been proposed to avoid the unnecessary creation of the loop ileostomy. The article presents literature data on the use of virtual ileostomy for resection interventions on the rectum with the formation of a low colorectal anastomosis. According to most authors, the virtual ileostomy technique allows not only to avoid the unnecessary formation of the loop ileostomy, but also in the anastomotic leakage, it ensures the urgent application of the loop ileostomy in minimally invasive manner, without relaparotomy.
A Misleading Pain: Unravelling Pulmonary Embolism Masquerading as Flank Pain
Authors: Ahmed Heba , Neyadi Salama , Alnuaimi Maryam
Published: June 2024

Introduction
Pulmonary embolism (PE) is one of the commonly encountered diagnoses in the emergency department and poses a significant threat to patients' lives. However, there remains a diagnostic challenge due to the wide range of presentations, some of which can be atypical and thus misleading. In fact, pulmonary embolism has recently been named in the literature as the great masquerader. In this article we discuss a case of pulmonary embolism that presented with abdominal pain.
Case Presentation
We report a case of a 25-year-old female with a past medical history of hypertension and end stage renal disease on regular hemodialysis, who presented to the emergency with sudden onset, severe left sided flank pain radiating to the chest for 2 days. She noted that the pain was constantly present and worsened with breathing. She also reported black stools and one episode of spitting blood. She denied the presence of other symptoms. Her heart rate was fluctuating between 100-110 beats per minute, but otherwise her vitals were within normal limits. Physical examination revealed a soft, non-distended and non-tender abdomen. Lab work was significant for a C-reactive protein level of 311 mg/L and D-Dimer level of 7.19 mcg/mL. Chest X-ray showed a left lower lobe infiltrate with minimal pleural effusion. A computed tomography of the chest was ordered in view of her tachycardia and high D-dimer level. Results of the imaging revealed an acute pulmonary embolism of the left lower lobe segmental artery associated with pulmonary infarction.
Conclusion:
A missed diagnosis of PE can lead to severe consequences, warranting a high index of suspicion. In this case, the patient's initial complaints of abdomen pain masked the underlying condition. Moreover, our patient lacked the risk factors for a pulmonary embolism and had a well's score of 1.5 only, that was attributed to her tachycardia. She also had other symptoms that clouded her presentation and was pointing more towards an abdominal etiology. This goes to say that while pattern recognition aids in the medical decision-making process, it's important for the physician to keep an open mind when there's uncertainty. A high index of suspicion can significantly impact patient outcomes.

Body armor is critical to mitigating penetrating injuries and saving soldiers' lives. However, ballistic impacts to body armor can cause back deformation (BFD), posing a serious threat of fatal injury on the battlefield. The study performs finite element modeling to evaluate the protection of body armor panels. The numerical simulations consider various parameters, including impact velocities, and angles of projectile impact, which are used to estimate the residual velocity and damage patterns of the composite laminate. The simulations are carried out using the LS-DYNA code based on finite element analysis. The main results of the research reveal crucial insights into the ballistic behavior of composite materials with sisal and glass fibers. The study identifies specific responses, damage development patterns, and comparative analyses between sisal and fiberglass composites. The results have practical implications for the development of advanced materials to improve ballistic protection.

Published: June 2024

A study of fertility life tables of Raoiella indica was carried out on coconut (Cocos nucifera) leaflets at controlled temperature and relative humidity (RH) in Texcoco, Mexico, with the objective of estimating the parameters of population increase of this mite. Cohorts of 12-hour-old Raoiella indica eggs were incubated at 22.5, 25, 27.5 or 30 °C and 40-50 % RH, as well as 27.5 °C with 30-40, 60-70 or 80-90 % RH. They were observed daily until the last mite died. Females that attained adulthood were provided with two males to promote mating and their oviposition was recorded daily. Each one-day-old male was put in contact with a female quiescent deutonymph daily to determine how many times a male could copulate after the deutonymph became an adult. With all temperatures and RH’s, mortality was evenly distributed throughout the observations. Developmental rate, reproduction, and, consequently, parameters of population increase were significantly associated with temperature. The highest rate of population increase took place at 27.5 °C and 40-40 RH. By itself, RH did not significantly affect those variables, although its extreme values showed slight negative effects. Approximately four females per male were observed. Males copulated with 4.56 females on average; this suggests that between 20 and 30 % of the males are enough to fertilize all females present.

The intense competition between developers, resulting in efforts to determine users' needs, is increasingly important. Usability An application can affect the continuity of application use. In this study, the user's loyalty is also used to analyze usability. This study examines user perceptions about user interaction characteristics when interacting with the mobile commerce application and considers users' loyalty. This research is essential to find out the needs of users of a mobile commerce application, which can be input to the developer in the design stage. This study uses 149 respondents' online shopping transactions in Jabadetabek and outside Jabodetabek, Indonesia. Data were analyzed using the Structural Equation Modeling (SEM) model. The results showed that users' perception of effectiveness, satisfaction, and learning influenced usability. This model can explain 42.6% of the user's usability variation when using it. This model can explain the usability of the Mobile Commerce application quite well. As a practical implication, this study shows the factors that support the characteristics of user interaction and application systems at the stage of defining the requirements for developing mobile commerce applications.

Objetivo: Identificar as dimensões humanas física, psicológica, social e espiritual expressas pelos indicadores clínicos de diagnósticos de enfermagem.  Métodos: Revisão integrativa de literatura, realizada entre dezembro de 2022 e janeiro de 2023, nas bases de dados Cumulative Index to Nursing and Allied Health Literature, Scopus, Excerpta Medica Database e PubMed, com equações de combinações das palavras-chave “nursing diagnoses”, “clinical indicators”, “validation studies”, “data accuracy” e “realiability”. Resultados: Nos 19 artigos incluídos na pesquisa, foram identificados 266 indicadores clínicos em 21 diagnósticos de enfermagem. Nove diagnósticos incluíram, exclusivamente, indicadores da dimensão física e um, da dimensão psicológica; seis diagnósticos contemplaram indicadores das dimensões física e psicológica; nove diagnósticos incluíram combinações de duas ou mais dimensões; apenas o diagnóstico “processos familiares disfuncionais relacionados ao abuso de álcool” inseriu indicadores de todas as dimensões. A dimensão espiritual foi representada por um indicador. Conclusão: A difusão do modelo biomédico ocasionou sua incorporação pelos serviços de saúde e, consequentemente, pela enfermagem. Embora o domínio do conhecimento ligado às necessidades fisiológicas favoreça o cuidado do corpo humano, fica explícito que a enfermagem deve identificar indicadores das outras dimensões humanas, a fim de prestar e registrar o cuidado holístico.

Objectives

Post-mastectomy seroma and haematoma increase morbidity and overall healthcare costs among patients undergoing mastectomy. Electrocautery and scissors are tools frequently used to raise the flap during mastectomy, each having advantages and disadvantages as to forming seroma and haematoma. The present study compared the incidence and volume of post-mastectomy seroma and haematoma following sharp and electrocautery dissection in mobilising flaps.

Material and Methods

A two-centre prospective, randomised comparative study involving patients with histologically diagnosed breast cancer who underwent mastectomy. Participants were randomly divided into two groups. Group A had electrocautery dissection and haemostasis, while group B had scissors dissection and haemostasis achieved by ligation and pressure packing. Seroma and haematoma formation, including Volume, surgery duration of drainage, and estimated blood loss, were recorded and analysed using SPSS for Windows version 25 (IBM Corp. Armonk, NY).

Results

The incidence of seroma was 60.9% for group A and 34.8% for Group B, while the mean duration of seroma drainage in Group A was 8.1 ± 0.7 and 6.6 ± 0.7 for Group B (p < 0.001). The mean total volume of seroma drained in group A was 587.9 ± 84.6, while that for Group B was 470.0 ± 75.2 (p = 0.004). The incidence of haematoma formation was 8.7% for group A and 4.3% for Group B (p = 0.550).

Conclusion

Sharp dissection significantly reduces the volume and duration of seroma drainage.

Perpustakaan masjid didirikan untuk memenuhi kebutuhan informasi di lingkungan masjid. Saat ini terdapat beberapa perpustakaan masjid yang pengelolaan dan pelayanannya masih bersifat manual. Oleh karena itu dibutuhkan sistem informasi perpustakaan untuk melakukan otomasi dan manajemen perpustakaan secara terkomputerisasi. Hal ini sesuai dengan perencanaan Kementerian Agama Provinsi Kalimantan Barat untuk membangun sistem informasi perpustakaan masjid di Kota Pontianak yang bertujuan untuk memudahkan lembaga masjid dalam mengelola bantuan bahan pustaka yang diperoleh dari pemerintah. Sistem informasi perpustakaan dapat membantu petugas perpustakaan untuk melakukan pengelolaan buku, proses peminjaman dan pengembalian buku serta mengurangi risiko kehilangan buku. Teknologi yang digunakan pada penelitian ini yaitu menerapkan framework flutter yang merupakan sebuah SDK (Software Development Kit) yang digunakan untuk mengembangkan aplikasi mobile yang dibuat oleh Google untuk membangun aplikasi yang memiliki performance yang tinggi dan dapat dipublikasikan untuk platform Android dan iOS. Hasil penelitian ini berupa sistem informasi perpustakaan berbasis mobile menggunakan framework Flutter sebagai front- end dan berbasis web menggunakan framework Laravel sebagai back-end yang dapat mempermudah lembaga masjid dalam mengelola bantuan bahan pustaka dari Kementerian Agama Provinsi Kalimantan Barat dan memudahkan masyarakat untuk melakukan pelayanan peminjaman buku. Dari hasil pengujian fungsional diperoleh bahwa sistem dapat berjalan sesuai dengan rancangan fungsional sistem. Sedangkan pengujian interface kepada masyarakat umum masuk ke dalam kategori sangat baik dengan persentase 84,94%.

Sugar gliders are nocturnal, which means they are active at night. Sugar Glider food ingredients use SUN brand cereal milk. The dose of feed for 1 meal is 6 grams of powder and 8 ml of water. To provide food on time, a tool is needed that can perform processing and feeding in the Sugar Glider cage automatically and the status is monitored through the website interface. The components used are ultrasonic sensors, mini DC water pumps, servo motors, DC motors. The results of ultrasonic sensor readings on the sensor nodes are monitored through the website interface. The Sugar Glider automatic feed processor design applies the concept of Internet of Things (IoT) technology, namely data communication using a wireless network (without cables). The hardware is built using two nodes, namely the sensor node as a monitor for the stock of feed ingredients in the tank and the controller node as a feed processor based on an active schedule. Testing of feed processing automatically on the controller node starts from the request for schedule status data to the server. The processing of feed based on the schedule entered on the website was successfully carried out by the system. The system succeeded in removing feed powder with an average value of 5.8 grams of powder coming out close to 6 grams and removing water with an average value of 8.4 ml approaching 8 ml. Testing of data transmission has been successfully carried out and the data is displayed on the website in real time.

Computer Based Test (CBT) merupakan salah satu bukti dari perkembangan teknologi informasi, pemanfaatan sistem CBT merupakan jawaban dari permasalahan yang terjadi jika pelaksanaanya secara konvensional. Penerapan sistem CBT tidak selalu berjalan sesuai harapan pada implementasinya. Oleh karena itu, diperlukan pengukuran untuk mengetahui bagian-bagian yang harus dipertahankan atau ditingkatkan sehingga dapat menghasilkan kualitas yang lebih baik lagi. Penelitian ini menggunakan Software Quality Metrics dan ISO/IEC 25010:2011 yang merupakan standar pengukuran kualitas yang memiliki karakteristik seperti adanya fitur compatibillity yang tidak terdapat pada standar pengukuran lain. Penelitian untuk metode pertama yaitu wawancara menggunakan Software Quality Metrics kepada pihak pengelola dari CBT. Hasil wawancara terkait Fungsional CBT menggunakan Software Quality Metrics belum pernah diterapkan pada praktiknya. Hasil penelitian menggunakan metode kedua yaitu ISO/IEC 25010, melalui jawaban kuesioner dari responden dicari kesenjangan yaitu antara kinerja dan harapan pengguna terhadap CBT menggunakan analisis gap.  Hasil yang diperoleh dari ke-13 dimensi yang memiliki nilai gap tertinggi berada pada dimensi Reliability, sebesar  -0,492 nilai kesenjangan terendah -0,21 terdapat pada dimensi Security.

Tomat  merupakan salah satu tanaman hortilkultura di Indonesia yang sangat rentan terserang penyakit, sehingga pengenalan penyakit pada tanaman tomat diperlukan untuk mencegah kerusakan yang lebih lanjut. Penyakit yang menyerang tanaman tomat dapat disebabkan oleh bakteri, jamur maupun virus. Sebagian besar gejala penyakit dapat dilihat pada perubahan warna dan bentuk pada daun. Kebanyakan yang dilakukan petani adalah mengenali gejala dengan mata telanjang dan langsung mengambil tindakan tanpa tahu cara penanggulangannya. Dari permasalahan tersebut, dilakukan penelitian untuk mengidentifikasi penyakit pada tanaman tomat dengan melihat warna dan bentuk daun. Penelitian ini bertujuan untuk membuat suatu aplikasi identifikasi penyakit pada tanaman tomat yang memanfaatkan pengolahan citra digital dengan proses ekstraksi fitur warna HSV dan bentuk menggunakan metode deteksi tepi operator sobel dan metode Naive Bayes Classifier untuk proses identifikasi.  Berdasarkan hasil pengujian menggunakan 47 sampel citra daun, dimana masing-masing jenis daun digunakan 7 sampai 10 sampel citra, memberikan persentase keberhasilan dalam identifikasi sebesar 82,98%. Kata kunci : penyakit tanaman tomat, citra digital, warna daun, bentuk daun, warna HSV, operator sobel, Naive Bayes Classifier.
