As avaliações econômicas têm implicações importantes para os apicultores, pois fornecem informações valiosas sobre as escolhas de configuração de colmeias que podem afetar positivamente a viabilidade econômica da produção de mel. O presente estudo se concentrou na viabilidade econômica da implantação de apiários a fim de obter 100 colmeias produtivas, tendo o mel como produto principal, explorando a adaptação do número de quadros de melgueiras em colmeias Langstroth. Especificamente, investigou-se a produção de mel, comparando colmeias com 8 quadros nas melgueiras e o padrão Langstroth, com 10 quadros. A avaliação econômica compreendeu custos fixos e custos variáveis e a condição de um apiário no primeiro ano da implantação, com a primeira safra de produção de mel. Os resultados revelaram que a produção de mel por melgueira com 8 quadros foi semelhante às com 10 quadros (8,8 e 8,9 kg/melgueira, respectivamente). Além disso, o custo operacional total que contabilizou o custo operacional acrescido de outras despesas (impostos e depreciação) nas colmeias modelo padrão foi de R$ 178.200,75, receita bruta de R$ 186.900,00 e receita líquida de R$ 8.699,25, além do melhor desempenho em todos os indicadores econômicos aplicados. Nas colmeias com 8 quadros, o custo operacional total foi de R$ 167.713,88, receita bruta de R$ 184.800,00 e receita líquida de R$ 17.086,13. Com base nos resultados, a produção de mel com 8 quadros nas melgueiras demonstra uma viabilidade econômica superior em comparação com o padrão Langstroth no primeiro ano, como indicado pela receita líquida 1,96 vezes maior.

Abstrak
Sistem Ekonomi Islam marak diperbincangkan di Indonesia. Istilah ini baru populer di Indonesia, sementara itu di negara lain sudah terlebih dahulu berkembang. Di Malaysia perkembangannya telah sedemikian pesat, begitu juga di beberapa Negara Timur Tengah. Membahas tentang Sistem Ekonomi Islam ternyata cukup memberikan corak yang berbeda. Salah satu penyebabnya adalah karena sistem ekonomi Islam memberi ciri utama yang berlandaskan pada syariat Islam, berbeda dengan ekonomi konvensional yang berlandaskan pada sistem ekonomi kapitalis atau disebut juga dengan ekonomi sekuler.
Penelitian ini merupakan penelitian lapangan (field research). Meneliti tentang Persepsi dan pendapat para tokoh agama yang ada di tengah-tengah masyarakat secara umum. Metode pengumpulan data dengan cara observasi, wawancara, kuesioner, dan dokumentasi. Analisis datanya bersifat Deskriptif Analisis dimana data yang diperoleh dianalisis dan kemudian diberikan penjelasan dan kesimpulan.
Sistem ekonomi Islam berupaya untuk melawan prinsip riba, maysir dan gharar yang menjadi prinsip utama dalam penerapan sistem ekonomi konvensional. Dalam setiap transakasi ekonomi konvensional selalu mengedepankan ketiga prinsip tersebut. Dampak yang ditimbulkan dari praktik tersebut kemudian membawa bencana dalam kehidupan sosial masyarakat seperti eksploitasi, distribusi pendapatan dan kekayaan yang tidak adil, lunturnya sikap kebersamaan dan persaudaraan, timbulnya permaslahan sosial dan sebagainya. Untuk itu persepsi tokoh agama tentang sistem ekonomi Islam sangat penting untuk diteliti dalam proses kajian, diskusi dan pembelajaran, agar masyarakat memiliki landasan utama dalam setiap tindakan dan praktik ekonominya.

Abstract
Creative Economic Empowerment Strategy Through the Business of Weaver Craftsman in Improving Community Welfare in the Pujut district. Central lombok islamic economic perspective (study on craftsmanRembitan village weaning)
Lombok is one of the many islands in Indonesia, this island is a place that has a lot of local wealth, this can be seen from the richness of biodiversity as well as art and culture. The potential for local wealth can be a major factor in advancing the creative economy in that place. However, from what we know, the average population of Lombok is lower middle class. Therefore, of the many economic theories that have emerged in the current era, researchers wish to apply one economic system, namely the creative economy, which relies on human resources as the main capital, especially the process of creation, creativity, expertise and individual talent. to make it easier for the community to improve the local economy. The problems raised in this research are divided into two things, namely: What are the strategies for empowering the creative economy in improving the welfare of groups of weaving craftsmen in Pujut sub-district from an Islamic economic perspective, and what are the inhibiting and supporting factors for empowering the creative economy of weaving craftsmen in Pujut sub-district. To find out more about this research, the researcher used descriptive qualitative research methods with data collection techniques used in the form of observation, interviews and documentation techniques. The research results show that the strategy for empowering the creative economy in improving the welfare of weaving crafts groups is: Providing facilities and conducting training regarding weaving craftsmen and exchanging information with craftsmen or local communities, who are experts in this field. Meanwhile, the inhibiting factors are lack of experience or knowledge in using technology in terms of marketing and others, lack of capital and raw materials, and lack of human resources.

ShallowBKGC: a BERT-enhanced shallow neural network model for knowledge graph completion
Authors: Jia Ningning , Yao Cuiyou
Published: May 2024

Knowledge graph completion aims to predict missing relations between entities in a knowledge graph. One of the effective ways for knowledge graph completion is knowledge graph embedding. However, existing embedding methods usually focus on developing deeper and more complex neural networks, or leveraging additional information, which inevitably increases computational complexity and is unfriendly to real-time applications. In this article, we propose an effective BERT-enhanced shallow neural network model for knowledge graph completion named ShallowBKGC. Specifically, given an entity pair, we first apply the pre-trained language model BERT to extract text features of head and tail entities. At the same time, we use the embedding layer to extract structure features of head and tail entities. Then the text and structure features are integrated into one entity-pair representation via average operation followed by a non-linear transformation. Finally, based on the entity-pair representation, we calculate probability of each relation through multi-label modeling to predict relations for the given entity pair. Experimental results on three benchmark datasets show that our model achieves a superior performance in comparison with baseline methods.

Retrospective analysis of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER2), Ki67 changes and their clinical significance between primary breast cancer and metastatic tumors
Authors: Qi Gaoxiu , Zhang Xin , Gai Xiaoying , Yan Xiong
Published: May 2024

Objective

To explore the relationship between receptor heterogeneity and clinicopathological characteristics in 166 patients with invasive breast cancer during metastasis.

Methods

We conducted a retrospective analysis of 166 patients diagnosed with metastatic breast cancer through biopsy, who were admitted to our hospital from January 2018 to December 2022. Statistical analysis was employed to assess the heterogeneity of receptors in both primary and metastatic lesions, including estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER2), Ki67, as well as their association with clinicopathological features such as tumor size, lymph node metastasis, treatment regimen, and disease-free survival.

Results

The discordant expression rates of ER, PR, HER2, Ki-67 and Luminal classification between primary and metastatic lesions were 21.7%, 41.6%, 8.9%, 34.4% and 36.8%, respectively. There is a significant difference in disease-free survival between patients with consistent and inconsistent receptor status of primary and metastatic lesions, which is statistically significant. The median DFS for primary HER2(-) to metastatic HER2(+) was 84 months, which was relatively high. The Cox multivariate regression analysis revealed that the expression differences of ER, PR, HER2, and Ki67 were not influenced by endocrine therapy and chemotherapy. However, a statistically significant difference in HER2 expression was observed with targeted therapy. Tumor size was correlated with ER and Ki67 receptor status (P = 0.019, 0.016). Tumor size was not correlated with PR, and HER2 (P = 0.679, 0.440). Lymph node metastasis was not associated with changes in ER, PR, HER2, and Ki67. The discordant rates of ER, PR, HER2, and Ki-67 in patients with local recurrence were 22%, 23.7%, 5.1%, and 28.8% respectively, whereas those in patients with distant metastasis were 21.5%, 36.4%, 10.3%, and 31.8% respectively.

Conclusions

The expression levels of ER, PR, HER2, and Ki-67 in primary and metastatic breast cancer exhibit heterogeneity, which is closely associated with the prognosis and treatment outcomes of patients.

No Brasil, atualmente, a Logística Reversa (LR) possui grandes desafios no controle dos materiais e o descarte incorreto devido a pouca informação que é entregue à sociedade, alertando os impactos como a contaminação à saúde e ao meio ambiente gerados, justamente, pela má administração dos resíduos sólidos das lâmpadas pós consumo. No contexto dos efeitos adversos, principalmente o ocasionado pelo acúmulo do mercúrio, tais resíduos oferecem altos riscos ao meio físico, biológico e antrópico pela liberação do vapor de mercúrio e contaminação dos solos e aquíferos pelo metal pesado. O objetivo deste artigo é apresentar a relevância da LR de lâmpadas no Brasil e os impactos do descarte inadequado, a partir de um estudo de caso da entidade sem fins lucrativos, Reciclus, gestora da LR de lâmpadas no Brasil responsável pela condução das lâmpadas pós consumo no país. Para isso, foi realizada uma entrevista complementar com diretor responsável pelo “Relatório de Atividades Ano-base 2019” da entidade. Este trabalho apresenta dados sobre a reciclagem de lâmpadas de mercúrio mostrando, como resultado, os impactos socioambientais que envolvem toda sua cadeia produtiva, desde o fabricante até o consumidor final.
The Nutritional Value of Heterotis niloticus ‘Ecomog Fish’ under Fresh, Smoked and Sun-dried Conditions in Calabar, Cross River State, Nigeria
Authors: P. S. Asangusung, , V. O Eyo,
Published: May 2024

The nutritional value (ash, moisture, fibre, protein, fat and carbohydrate) of three preservative states: fresh, smoked and sun-dried of Heterotis niloticus (Ecomog fish) in Cross River State, Nigeria was investigated, using the standard A. O. A. C (2005) methods. A total of nine matured size (3 – 4kg body weight) fishes were obtained from artisanal fishermen in Idundu (Great Kwa River). The fishes were divided into three groups; each group represented a treatment (preservative state). Samples were treated and laboratory studies carried out separately, before achieving proximate composition for each replicate. The results showed that, fresh H. niloticus gave the highest mean protein content (9.58±0.02%), mean moisture content (84.83±0.01g) and mean ash content (10.74±0.19%); smoked H. niloticus gave the highest mean fat content (17.53±0.04%) and mean fibre content (0.15±0.02%), while the sun-dried H. niloticus showed the highest value in mean carbohydrate content (76.60±0.01%). Although fresh H. niloticus is highly recommended for human consumption, in respect to our results; we may therefore conclude that these local sources of proteins are important not only in aiding to reduce high incidence of Protein Energy Malnutrition (PEM) among the lower socio-economic populace, but also as energy food source.

Authors: Asangusung, P. S.  , Uka, A.  , Nlewadim, A. A.
Published: May 2024

The economic evaluation of four hormonal preparations: Heterotis niloticus pituitary extract, ovaprim, Clarias gariepinus pituitary extract and carp pituitary extract (C.P.E) in artificial propagation of Heterotis niloticus was investigated. Total of twenty four fishes (twelve females and twelve males) of twenty four months old were used for the experiment. The females were divided into four groups.  Each group was induced to spawn with the same hormone. Sperm from one male was used to fertilize the eggs obtained from individual females. Effects of the hormones on the fecundity were investigated to help address the economic values. The results showed that the cost of inducing 2.20kg female to yield 30.33g, 47.00g, 30.00g and 29.33g of eggs, were ₦200, ₦700, ₦300 and ₦480, for Heterotis niloticus pituitary extract, ovaprim, Clarias gariepinus pituitary extract and C.P.E, respectively. Profitability index for Heterotis niloticus pituitary extract, ovaprim, Clarias gariepinus pituitary extract and C.P.E was 7, 10, 6.8 and 6.6, respectively. Indicating that, cost of production accounted <10% for ovaprim, <15% for CPE, and <14% for both HnPE and CgPE of the total variable cost. The production was more profitable with ovaprim than HnPE, CgPE and C.P.E. The study has provided data, comparing the effectiveness of the hormones, revealing that the four hormones can be used for artificial propagation of H. niloticus with varied degree of economic implication. However, ovaprim is highly recommended to hatchery users for optimum performance.

Flower forcing, which stimulates flowering at specific dates or during off-season periods, is a key technique employed. The manipulated flowering dates resulting from flower forcing may deviate from the plant's natural schedule, occurring either earlier or later than the standard flowering dates. This can be achieved by adjusting factors affecting flowering such as temperature, photoperiod, and irradiance etc. Implementation of special practices like pruning, leaf trimming, dormancy breaking helps in forcing operation in certain plants. Utilization of chemicals such as plant hormones like gibberellin and ethylene, growth retardants and some fertilizers also play an important role in forcing. Employing mechanical methods can be considered as a sustainable and environment friendly practice. Advancements in plant physiology, photomorphogenesis, metabolism, and greenhouse technologies have led to the development of multiple strategies to finely regulate the rate of plant growth and development across various crops.

Taking care of soil health is most importance for sustainable crop production. Soil quality is a blending of soil processes and provides to a measure change in soil condition as related to following factors such as land use, climate patterns, cropping sequences and farming systems.  In the present investigation analysis of different physical and chemical characteristics were made to determine soil health of Bokaro district. Results show that soil bulk density was in normal range, soil pore space % varied from 39.85 to 48.32 g cm-3, particle density ranged from 2.24 to 2.69 Mg m-3, water holding capacity varied from 34.23 to 43.86 %. Soil pH and EC were found to be acidic and non-saline in nature respectively while soil organic carbon and available phosphorus were in medium to high range. Available nitrogen and potassium were found to be low to medium range i.e., 197.0 to 219.0 Kg ha - 1 and 201.96 to 266.01 Kg ha -1 and the range of phosphorus varied from 16.96 to 26.68 kg ha -1 respectively. Deficiency of sulphur followed by zinc was found in soils of Bokaro district.

Workflow nets, a particular class of Petri nets, have become one of the standard ways to model and analyze workflows. Typically, they are used as an abstraction of the workflow that is used to check the so-calledsoundness property. This property guarantees the absence of livelocks, deadlocks, and other anomalies that can be detected without domain knowledge. Several authors have proposed alternative notions of soundness and have suggested to use more expressive languages, e.g., models with cancellations or priorities. This paper provides anoverview of the different notions of soundness and investigates these in the presence of different extensions of workflow nets. We will show that the eight soundness notions described in the literature are decidable for workflow nets. However, most extensions will make all of these notions undecidable. These new results show the theoretical limits of workflow verification. Moreover, we discuss some of the analysis approaches described in the literature.
Exploring Hereditary Cancer Among Dying Cancer Patients—A Cross‐Sectional Study of Hereditary Risk and Perceived Awareness of DNA Testing and Banking

Published: August 2010

Hereditary cancer assessment at the end of life is a relatively unexplored area, but it could be critical for surviving family members. This study explored the prevalence of hereditary cancer among dying cancer patients and assessed patients’ perceived awareness of DNA testing and/or banking in a public access hospital. Palliative care patients with cancer from a single institution (or their medical‐decision‐making surrogates for patients unable to answer for themselves) completed structured interviews. Information was collected through medical records review and structured interviews for 43 dying cancer patients. Information for 9 patients was collected from surrogates. Nine patients (21%, 95% CI = 8.8% to 33.1%) had strong genetic risk. Currently available genetic tests could have addressed this risk for several patients. None had previous genetic counseling, testing or DNA banking. Among strong‐risk patients, about half of patients/surrogates had heard/read “almost nothing” about genetic testing (44%) and DNA banking (67%). Perceived genetic awareness was not associated with genetic risk, and neither were sociodemographic characteristics. The proportion of hereditary cancer may be at least as high in the palliative care population as in other clinical settings, but awareness and uptake among patients are low. These conditions are not being recognized upstream and families are losing valuable information.

Published: August 2010

This study is an investigation of the impact of familial amyloid polyneuropathy type I (FAP I, ATTR V30M) on death anxiety and symbolic immortality. Templer and Drolet's scales were administered to 524 individuals: (1) 84 relatives at risk, (2) 92 relatives not at risk for FAP I; and (3) a control group (n = 348) with no known hereditary disease in their families. At‐risk relatives had, on average, a higher score for death anxiety and a lower score for symbolic immortality, than either those not‐at‐risk or controls. There were no significant differences in scores on either measure for those not‐at‐risk versus controls. Being at risk increases death anxiety and threatens the sense of symbolic immortality and psychosocial wellbeing. This may be true for other serious hereditary disorders as well. Genetic counsellors should become familiar with these concepts, feel comfortable initiating discussions about death with their patients, and be able to identify and reinforce their patients’ and family members’ sense of symbolic immortality.
Impediments to DNA Testing and Cascade Screening for Hypertrophic Cardiomyopathy and Long QT syndrome: A Qualitative Study of Patient Experiences
Authors: Smart Andrew
Published: August 2010

This paper reports data from a qualitative study of patient experiences of DNA testing and cascade screening for hypertrophic cardiomyopathy and long QT syndrome, cardiac conditions that place sufferers at risk of sudden death. The paper particularly focuses on potential impediments to testing and screening. Semi‐structured interviews were undertaken with a purposive sample of 27 people in the UK who had undergone testing. In the context of the uncertainties that can characterize experiences of these disorders, the majority of participants in this sample embraced testing and screening as a way of providing health information for themselves or their relatives (particularly children). There was nevertheless evidence of ambivalence about the value and impact of the DNA test information which could influence participants’ dispositions toward testing, and play into dilemmas about family communication. Other concerns arose in relation to communicating about these disorders, decisions to involve elderly relatives and pressures relating to family responsibility. The evidence of ambivalence provides insight into why some people may be resistant to testing, screening and sharing information. The findings about communication processes indicate potential areas of concern for the cascading process.
Tests of Homoscedasticity, Normality, and Missing Completely at Random for Incomplete Multivariate Data
Authors: Jamshidian Mortaza , Jalal Siavash
Published: August 2010

Test of homogeneity of covariances (or homoscedasticity) among several groups has many applications in statistical analysis. In the context of incomplete data analysis, tests of homoscedasticity among groups of cases with identical missing data patterns have been proposed to test whether data are missing completely at random (MCAR). These tests of MCAR require large sample sizes n and/or large group sample sizes ni, and they usually fail when applied to nonnormal data. Hawkins (Technometrics 23:105–110, 1981) proposed a test of multivariate normality and homoscedasticity that is an exact test for complete data when ni are small. This paper proposes a modification of this test for complete data to improve its performance, and extends its application to test of homoscedasticity and MCAR when data are multivariate normal and incomplete. Moreover, it is shown that the statistic used in the Hawkins test in conjunction with a nonparametric k-sample test can be used to obtain a nonparametric test of homoscedasticity that works well for both normal and nonnormal data. It is explained how a combination of the proposed normal-theory Hawkins test and the nonparametric test can be employed to test for homoscedasticity, MCAR, and multivariate normality. Simulation studies show that the newly proposed tests generally outperform their existing competitors in terms of Type I error rejection rates. Also, a power study of the proposed tests indicates good power. The proposed methods use appropriate missing data imputations to impute missing data. Methods of multiple imputation are described and one of the methods is employed to confirm the result of our single imputation methods. Examples are provided where multiple imputation enables one to identify a group or groups whose covariance matrices differ from the majority of other groups.
