Facilitation in Education: Historical and Pedagogical Dimension
Authors:   State Institution Luhansk Taras Shevchenko National University, Vakhovskyi Leonid
Published: February 2022

The article deals with the origins of facilitation as a way of organizing the joint activities of participants in the educational process, outlines the direction of its transformation in the historical dynamics. It is shown that the beginnings of the facilitative approach can be traced in the dialogical method of teaching used by Socrates. The basis for the application of the ideas of facilitation in education were also the principle of naturalness of education and Ya. A. Komenskyi’s classroom system, J. Locke’s empirical-sensualist theory of knowledge, J.-J. Rousseau’s concept of free education, J. H Pestalozzi’s theory of elementary education. The significance of foreign reformist pedagogy of the end of the XIX – beginning of the XX century, which offered new systems and methods of teaching, including group education of children, is revealed. This required from the teacher new qualities, the ability to organize effective interaction with students, i.e. the presence of certain facilitative skills. The contribution of the famous psychologist K. Rogers, an ardent supporter of human-centered learning in substantiating the idea of facilitation in education, is considered. The scientist proceeded from the fact that the disadvantage of the traditional system of education is the overestimation of the role of teaching and teachers and the underestimation of the role of conscious learning and student. He insisted on the need to shift the emphasis from teaching to learning and advised teaching not as a translation of information, but as a facilitation of the processes of conscious learning.
The management of anti-neutrophil cytoplasmic antibody-associated vasculitis: what has changed in the last 10 years?
Authors: Suresh Ernest
Published: February 2022

The management of anti-neutrophil cytoplasmic antibody-associated vasculitis has substantially improved in the last decade. For the induction of remission, rituximab is increasingly used in place of cyclophosphamide, particularly for patients with proteinase 3 (PR3)-associated vasculitis or relapsing disease, and those wishing to preserve their fertility. A lower dose regimen of glucocorticoids, with a more rapidly tapering schedule, is preferable and is as effective and safer than the standard-dose regimen. Avacopan, the complement C5a receptor inhibitor, is effective in the treatment of associated vasculitis and may replace glucocorticoids in the future. Plasma exchange provides no additional benefit for patients with severe anti-neutrophil cytoplasmic antibody-associated vasculitis, although it is still used in selected patients on a case-by-case basis. Rituximab is preferred for the maintenance of remission, repeated at fixed time intervals. The duration for which immunosuppressive therapy should be given is uncertain, but is generally longer for patients with PR3 disease or persistent anti-neutrophil cytoplasmic antibody positivity. The anti-interleukin 5 monoclonal antibody, mepolizumab, is effective for the treatment of non-severe eosinophilic granulomatosis with polyangiitis. Several other targeted therapies are in the pipeline and further progress is expected in the coming years.
Majorization inequalities via convex functions
Authors: Kian Mohsen , Sababheh Mohammad
Published: February 2022

Convex functions have been well studied in the literature for scalars and matrices. However, other types of convex functions have not received the same attention given to the usual convex functions. The main goal of this article is to present matrix inequalities for many types of convex functions, including log-convex, harmonically convex, geometrically convex, and others. The results extend many known results in the literature in this direction. For example, it is shown that if $A,B$ are positive definite matrices and $f$ is a continuous $\sigma\tau$-convex function on an interval containing the spectra of $A,B$, then\begin{align*}\lambda^\downarrow (f(A\sigma B))\prec_w\lambda^\downarrow \left(f(A)\tau f(B)\right),\end{align*}for the matrix means $\sigma,\tau\in\{\nabla_{\alpha},!_{\alpha}\}$ and $\alpha\in[0,1]$. Further, if $\sigma=\sharp_{\alpha}$, then\begin{align*} \lambda^\downarrow \left(f\left(e^{A\nabla_{\alpha}B}\right)\right)\prec_w\lambda^\downarrow \left(f(e^A)\tau f(e^B))\right).\end{align*}Similar inequalities will be presented for two-variable functions too.
Megahertz-rate background-oriented schlieren tomography in
post-detonation blasts

Published: February 2022

The understanding and predictive modeling of explosive blasts require
advanced experimental diagnostics that can provide information on
local state variables with high spatiotemporal resolution. Current
datasets are predominantly based on idealized spherically symmetric
explosive charges and point-probe measurements, although practical
charges typically involve multidimensional spatial structures and
complex shock-flow interactions. This work introduces megahertz-rate
background-oriented schlieren tomography to resolve transient,
three-dimensional density fields, as found in an explosive blast,
without symmetry assumptions. A numerical evaluation is used to
quantify the sources of error and optimize the reconstruction
parameters for shock fields. Average errors are

%

in the synthetic environment, where
the accuracy is limited by the deflection sensing algorithm. The
approach was experimentally demonstrated on two different commercial
blast charges (Mach

and

) with both spherical
and multi-shock structures. Overpressure measurements were conducted
using shock-front tracking to provide a baseline for assessing the
reconstructed densities. The experimental reconstructions of the
primary blast fronts were within 9% of the expected peak values. The
megahertz time resolution and quantitative reconstruction without
symmetry assumptions were accomplished using a single high-speed
camera and light source, enabling the visualization of multi-shock
structures with a relatively simple arrangement. Future
developments in illumination, imaging, and analysis to improve the
accuracy in extreme environments are discussed.
Measuring the spectral response of a division-of-focal-plane
polarization imager using a grating monochromator
Authors: Venkatesulu Erica , Shaw Joseph A.
Published: February 2022

Spectral characterizations are performed on imagers to obtain a
relative spectral response (RSR) curve. This process often utilizes a
grating monochromator with an output that changes polarization as a
function of wavelength (our monochromator’s degree of linear
polarization was found to vary from less than 10% to more than 70%).
When characterizing a polarization-sensitive imager, this introduces
polarization artifacts into the RSR curve. We present a simple method
to avoid these polarization artifacts for division-of-focal-plane
polarization imagers by directly illuminating the camera with the
monochromator output and calculating the S0 Stokes
parameter at each super pixel, then we show consistent results from
this method for two division-of-focal-plane polarization imagers. We
also show that ignoring the monochromator polarization results in
order-of-magnitude RSR errors. The recommended method uses an iris to
limit the spatial extent of the monochromator output, which was found
experimentally to increase the minimum signal-to-noise ratio by more
than a factor of 2.

Published: February 2022

Here we introduce a fiber amplifier and a diamond Raman laser that output high powers (6.5 W, 1.3 W) at valuable wavelengths (1060 nm, 1250 nm) for two-photon excitation of red-shifted fluorophores. These custom excitation sources are both simple to construct and cost-efficient in comparison to similar custom and commercial alternatives. Furthermore, they operate at a repetition rate (80 MHz) that allows fast image acquisition using resonant scanners. With our system we demonstrate compatibility with fast resonant scanning, the ability to acquire neuronal images, and the capability to image vasculature at deep locations (>1 mm) within the mouse cerebral cortex.
All-optical dynamic modulation of spontaneous emission rate in hybrid optomechanical emitter-cavity systems

Published: February 2022

Optomechanics is the study of the interaction between nano-objects and light fields through radiation pressure. Recent sophisticated optomechanical systems consist of strongly coupled mechanical and optical resonators and are made using semiconductor nanofabrication techniques. Although the optomechanical systems have exhibited their powerful capability of controlling photons, they are scarcely used to control the solid-state artificial atoms that emit photons. The main reason is that an efficient coupling mechanism remains unexplored. Here, we hybridize a silicon-integrated optomechanical resonator with two-level atom-like emitters to demonstrate an optomechanical cavity quantum electrodynamic (cQED) effect. With this system and the effect, we realize the dynamic modulation of the spontaneous emission rate. We choose copper dopants in silicon as the emitters for its narrow linewidth (0.3 nm) and long lifetime (

∼

30

n
s

). Our judiciously designed coupled-nanobeam optomechanical resonator achieves a strong Purcell effect and high cavity-modulation performances. The optical cavity of the optomechanical resonator is dynamically coupled to the emission line and, as a result, on-demand sharp pulses (up to 9.5-fold intensity enhancement and 3.5 ns in duration, which is one ninth of the emission lifetime) appear along the photoluminescence decay. These experimental results are exactly explained with an analytical model that combines optomechanical and cQED theories. Considering that dopants in silicon are highly competitive qubits, we believe that our optomechanical cQED technology will find important applications in the quantum era.

Published: February 2022

Background and objective

Tuberculosis (Tuberculosis, TB) is a public health problem in China, which not only endangers the population’s health but also affects economic and social development. It requires an accurate prediction analysis to help to make policymakers with early warning and provide effective precautionary measures. In this study, ARIMA, GM(1,1), and LSTM models were constructed and compared, respectively. The results showed that the LSTM was the optimal model, which can be achieved satisfactory performance for TB cases predictions in mainland China.

Methods

The data of tuberculosis cases in mainland China were extracted from the National Health Commission of the People’s Republic of China website. According to the TB data characteristics and the sample requirements, we created the ARIMA, GM(1,1), and LSTM models, which can make predictions for the prevalence trend of TB. The mean absolute error (MAE), root mean square error (RMSE), and mean absolute percentage error (MAPE) were applied to evaluate the effects of model fitting predicting accuracy.

Results

There were 3,021,995 tuberculosis cases in mainland China from January 2018 to December 2020. And the overall TB cases in mainland China take on a downtrend trend. We established ARIMA, GM(1,1), and LSTM models, respectively. The optimal ARIMA model is the ARIMA (0,1,0) × (0,1,0)12. The equation for GM(1,1) model was X(k+1) = -10057053.55e(-0.01k)+ 10153178.55 the Mean square deviation ratio C value was 0.49, and the Small probability of error P was 0.94. LSTM model consists of an input layer, a hidden layer and an output layer, the parameters of epochs, learning rating are 60, 0.01, respectively. The MAE, RMSE, and MAPE values of LSTM model were smaller than that of GM(1,1) and ARIMA models.

Conclusions

Our findings showed that the LSTM model was the optimal model, which has a higher accuracy performance than that of ARIMA and GM (1,1) models. Its prediction results can act as a predictive tool for TB prevention measures in mainland China.
What influences whether parents recognise COVID-19 symptoms, request a test and self-isolate: A qualitative study
Authors: Woodland Lisa , Mowbray Fiona , Smith Louise E. , Webster Rebecca K. , Amlôt Richard , Rubin G James
Published: February 2022

Background

Using test, trace and isolate systems can help reduce the spread of COVID-19. Parents have the additional responsibility of using these systems for themselves and acting on behalf of their children to help control COVID-19. We explored factors associated with the use of England’s NHS Test and Trace service among parents of school-aged children.

Methods

One-to-one telephone interviews with parents (n = 18) of school-aged (4 to 18 years) children living in England between 30 November to 11 December 2020. Data were explored using thematic analysis.

Results

Three themes and eight sub-themes emerged. In terms of recognising symptoms of COVID-19, parents needed prompting before recalling the main symptoms described by the NHS. Parents suggested several factors relating to the nature of the symptom(s) and contextual information that might lead to or prevent them from seeking a test. Although parents supported symptomatic testing and described trusting official sources of information (e.g., Government and NHS websites). However, some concerns were raised regarding the accuracy of test results, safety at testing centres and logistics of testing but none of the concerns appeared to prevent engagement with testing. Parents perceived adherence to testing and self-isolation as pro-social behaviour, although family resources and circumstances impacted their ability to adhere fully.

Conclusions

Our study identified several barriers to parents using NHS Test and Trace as needed. Information about the eligibility of testing (main symptoms of COVID-19 and the age of eligibility) needs to be more precise and resources provided to enable families to adhere to self-isolation if the efficiency of test, trace and isolate systems is to be optimised.
Survival analysis of cancer patients using a new extended Weibull distribution
Authors: Klakattawi Hadeel S.
Published: February 2022

One of the most important applications of statistical analysis is in health research and applications. Cancer studies are mostly required special statistical considerations in order to find the appropriate model for fitting the survival data. Existing classical distributions rarely fit such data well and an increasing interest has been shown recently in developing more flexible distributions by introducing some additional parameters to the basic model. In this paper, a new five-parameters distribution referred as alpha power Kumaraswamy Weibull distribution is introduced and studied. Particularly, this distribution extends the Weibull distribution based on a novel technique that combines two well known generalisation methods, namely, alpha power and T-X transformations. Different characteristics of the proposed distribution, including moments, quantiles, Rényi entropy and order statistics are obtained. The method of maximum likelihood is applied in order to estimate the model parameters based on complete and censored data. The performance of these estimators are examined via conducting some simulation studies. The potential importance and applicability of the proposed distribution is illustrated empirically by means of six datasets that describe the survival of some cancer patients. The results of the analysis indicated to the promising performance of the alpha power Kumaraswamy Weibull distribution in practice comparing to some other competing distributions.
Correlation analysis of m6A-modified regulators with immune microenvironment infiltrating cells in lung adenocarcinoma
Authors: Ye Wei , Huang Tianpeng
Published: February 2022

Object

Recent studies have demonstrated the epigenetic regulation of immune responses. However, the potential role of N6-methyladenosine methylation (m6A) in the tumor microenvironment (TME) remains unknown.

Method

In this study, the m6A modification patterns of LUAD samples were comprehensively evaluated by combining TCGA and GEO data, while these modification patterns were systematically linked to the characteristics of immune infiltrating cells in TME. The m6A score was constructed using the principal component analysis algorithm to quantify the m6A modification mode of a single tumor.

Result

There were three distinct patterns of m6A modification identified. The characteristics of TME cell infiltration in these three patterns were highly consistent with these three immune phenotypes of the tumors, including immune rejection, immune-inflammatory, and immune inert phenotypes. Low m6A scores were characterized by immune activation and poor survival rate. Besides, m6A scores were associated with tumor mutational load (TMB) and were able to increase the ability of TMB to predict immunotherapy. Two immunotherapy cohorts confirmed that the patients with lower m6A scores demonstrated significant therapeutic advantages and clinical benefits. m6A modifications play an important role in the development of TME diversity. Assessing the m6A modification pattern of individual tumors can deepen the understanding as to the characteristics of TME infiltration and guide more effective immunotherapy strategies.

Az azonban fontos, hogy a válaszadók, illetve adatközlők egyes emberek legyenek (Babbie [1965] 1995: 278.).
Interdiszciplináris programok a vizuális kutatásban: A vizuális antropológia újragondolása
Authors: Pink Sarah
Published: February 2022

Ebben a cikkben a vizuális kutatási módszerek legújabb szakirodalmát tekintem át, mégpedig két kérdés tisztázása céljából. Először is megvizsgálom, hogy a legújabb interdiszciplináris kölcsönhatások milyen képet alakítottak ki a vizuális kutatás alapító tudományáról és a reprezentációról a vizuális kutatásban, elsősorban a vizuális antropológiára (és kisebb mértékben a vizuális szociológiára) koncentrálva. Másodszor pedig kritikus szemmel a szaktudományaikból vizuális módszereket átemelő, illetve azok számára ilyen módszereket bevezető elméleti tudományok közös céljait és érdeklődési területeit. Ha elmélyedünk a vizuális kutatás „új keletű” szakirodalmában, világossá válik, hogy a különböző szaktudományokban dolgozó mai vizuális kutatóknak vannak közös érdeklődési területeik: ilyen a reflexivitás (reflexivity), az együttműködés, az etika, valamint a tartalom, a társadalmi kontextus és a képmások (images) anyagszerűsége közötti kapcsolat. Érvelni szeretnék a vizuális kutatómunka intenzívebben együttműködő interdiszciplináris megközelítése mellett, amelyben az egyes szaktudományok anélkül tanulhatnak egymástól, hogy narratív sallangokkal kellene bizonygatniuk saját tudományáguknak a többiekkel szembeni felsőbbségét.

Antecedentes: la infección vertical por SARS-CoV-2 en recién nacidos, tiene poca evidencia, sin embargo, cada vez hay más casos que sustentan dicha posibilidad. Por otro lado, si bien las infecciones a esta edad suelen ser leves, no se ha visto su comportamiento en neonatos nacidos a mayor altitud sobre el nivel del mar. Reporte de caso: presentamos a un neonato con alta probabilidad de haber contraído una infección vertical por el SARS-CoV-2, que tuvo una evolución tórpida con necesidad de soporte de oxígeno y que a su vez asoció hallazgos radiológicos de gran daño pulmonar demostrados por tomografía. El paciente mostró mejoría lenta y pudo ser dado de alta a los 14 días de vida sin mostrar dependencia de oxígeno. Conclusiones: Este caso expone nuestro limitado conocimiento del comportamiento de esta enfermedad en neonatos nacidos en altura.
Isolated Gastritis Secondary to Immune Checkpoint Inhibitors Complicated by Superimposed Cytomegalovirus Infection
Authors: Nguyen Anita H. , Sagvand Babak Torabi , Hwang Daniel G. , Legesse Teklu , Cross Raymond K.
Published: February 2022

Immune checkpoint inhibitors such as nivolumab increase the T-cell destruction of malignancies but can also trigger a broad variety of immune-related adverse events (irAEs). Colitis as an irAE is well-documented, but upper gastrointestinal tract involvement is primarily unrecognized. We present a patient who developed gastritis as an irAE after multiple cycles of nivolumab and initially responded well to steroid therapy but then developed superimposed cytomegalovirus infection. The similarity between both presentations highlights the importance of having a broad differential diagnosis in patients with gastrointestinal complaints treated with immune checkpoint inhibitors and the need for further studies to better characterize gastritis as an irAE.

Esta pesquisa busca compreender como teoria e prática propostas metodologicamente pela Escolinha de Agroecologia de Nova Iguaçu/RJ (EANI), a partir da sinergia entre ação pública e sociedade, contribuem para a estruturação de redes de aprendizagem mútua, para o fortalecimento da reprodução social da agricultura familiar agroecológica do município de Nova Iguaçu/RJ e para a permanência dos sujeitos envolvidos no território. O referencial teórico está fundamentado nas contribuições acerca dos sistemas alimentares, o desenvolvimento rural, a agroecologia, agricultura urbana e periurbana, o capital social, a capacidade de agência dos atores sociais e o território como espaço de relações, e formam o escopo para a análise dos resultados alcançados. A metodologia foi conduzida como um estudo de caso da experiência da EANI, baseada na aplicação de entrevistas semiestruturadas, utilizando a técnica de amostragem não probabilística da “bola de neve”, seguida da análise de conteúdo proposta por Bardin (1977). Os resultados demonstraram que as relações estabelecidas entre a EANI, as organizações parceiras e os movimentos e associações da agricultura familiar da Baixada Fluminense, estão apoiadas pela ação extensionista da Emater-Rio em parceria com a CPT-Baixada, através de um processo de construção do conhecimento a partir da valorização das experiências vividas pelos próprios beneficiários da EANI na construção de um território agroecológico, desencadeando um processo de catalização da capacidade de agência dos atores da agricultura familiar e consequentemente induzindo o desenvolvimento local, frente as dificuldades de acesso às políticas públicas, ausência do poder público municipal e pela pressão urbana exercida sobre as áreas produtivas.

The Investigation to the Learning Behaviour of Body Painting
Authors: WU LI-AN
Published: February 2022

Amid the emergence of body painting as a new art form in the modern fashion industry, a growing number of vocational-technical schools in Taiwan have included this form of art into their programs. This study aims to use the Theory of Planned Behavior (TPB) in order to explore the learning behavior of body painting respondents in terms of their subjective norm, descriptive norm, attitude, personal norm, perceived behavioral control and intention.

In the research process, a questionnaire survey was conducted among body painting respondents in an independent sampling approach with the collection of 260 valid samples. The data are analyzed by using the statistical software package SPSS. The results indicate that all variables of the subjects-subjective norm, descriptive norm, attitude, personal norm, and perceived behavioral control, have a significant positive influence on their intention. Meanwhile, attitude has a partial mediation effect on the relationship between subjective norm and descriptive norm to intention. Personal norm has a partial mediation effect on the relationship between subjective norm and descriptive norm to intention. Perceived behavioral control has a complete mediation effect on the relationship between subjective norm and descriptive norm to intention.

Pada era disrupsi saat ini, inovasi teknologi dan informasi terus mengalami perkembangan, salah satu contohnya adalah e-commerce. Namun pada pelaksanaannya, masih dijumpai beberapa kelemahan, salah satunya dalam sistem keamanan siber yang mengatur perlindungan data pribadi milik pengguna ecommerce yang mengakibatkan kebocoran data pribadi. Selain itu, belum adanya peraturan khusus terkait perlindungan data pribadi menyebabkan banyaknya permasalahan terkait kebocoran data pribadi. Hal ini bertentangan dengan Pasal 28G ayat (1) Undang-Undang Dasar Negara Republik Indonesia Tahun 1945 (UUD NRI Tahun 1945) yang menyatakan bahwa setiap orang berhak atas perlindungan diri pribadi. Penulisan ini memiliki tujuan untuk membantu mewujudkan penegakan keamanan siber di Indonesia. Karya tulis ilmiah ini menggunakan metode penulisan yuridis empiris. Metode pengumpulan data yang digunakan yaitu studi lapangan dengan melakukan wawancara dan studi kepustakaan, seperti peraturan perundang-undangan, buku dan jurnal. Ketika data sudah terkumpul, kemudian dianalisis mengunakan metode kualitatif. Berdasarkan hasil analisa yang telah dikumpulkan, bahwa sistem keamanan siber di Indonesia masih membutuhkan inovasi terhadap perlindungan data pribadi, yaitu berupa sistem keamanan blockchain. Penggunaan sistem blockchain memerlukan sebuah payung hukum agar keberadannya dapat mengurangi permasalahan kebocoran data pribadi. Berkaitan dengan hal itu, diperlukan kebijakan terkait sistem keamanan siber yang memiliki orientasi pada era disrupsi terhadap perlindungan data pribadi, yaitu Regulatory Blockchain. Dalam pelaksanaannya membutuhkan peran stakeholder, seperti Kementerian Komunikasi dan Informatika, serta Badan Siber dan Sandi Negara untuk merealisasikan Pasal 28G ayat (1) UUD NRI Tahun 1945.

Menjadi pengetahuan umum bahwa sekarang ini Indonesia sedang pada posisi krisis energi, dimana baru-baru ini adanya tindakan pencabutan ekspor batu bara karena menipisnya cadangan sumber daya energi kita. Adanya amanat dari konstitusi kita tepatnya pada Pasal 33 ayat (3) memerintahkan perut bumi nusantara untuk dikelola dan dimanfaatkan untuk seluruh rakyat. Ketimpangan pun terjadi ketika terjadi kelangkaan sumberdaya energi dan pengambilan kebijakan pemerintah yang terus saja terbatas pada keuntungan jangka pendek. Eksploitasi yang tidak dibarengi pada peningkatan kapasitas SDM di Indonesia pada penemuan sumberdaya baru memunculkan efek domino yang bisa menjadi bom waktu bagi Indonesia. Dalam penelitian ini penulis menemukan adanya potensi energi Bernama Torium yang bisa dimanfaatkan sebagai sumber dari energi terbarukan, Penulis akan mengelaborasi lebih lanjut mengenai kelebihan pemanfaatan energi nuklir sebagai jawaban dari keberlanjutan hukum energi dengan mendorong penggunaan bahan bakar thorium yang dipadukan dengan Molten Salt Reactor. Metode penelitian yang digunakan yaitu yuridis normatif, dengan beberapa pendekatan yaitu: pendekatan perundang-undangan, pendekatan konseptual, pendekatan historis, pendekatan kasus, dan pendekatan perbandingan. Berdasarkan penelusuran penulis ditemukan bahwa pemanfaatan Thorium dapat menjadi jawaban atas keberlangsungan ketahanan energi di Indonesia dan dari instrumen hukum kita berpeluang memberikan akses untuk itu. Dengan pertimbangan kapasitas energi dan keberlimpahan itu bisa menjawab persoalan sekarang ini. Kesimpulan, pemanfaatan Thorium dapat menjadi energi alternatif baru berbasis nuklir sebagai jawaban atas keberlangsungan ketahanan energi di Indonesia. Saran, menyarankan untuk melakukan maksimalisasi dengan cara memasukan rancangan ini pada prolegda dan direkomendasikan pada kebijakan pusat dan melakukan kajian lebih pada energi Thorium yang dilakukan kementerian Energi dan sumber daya alam serta.

Anak menjadi salah satu kelompok yang sangat rentan terhadap pelanggaran hak-haknya dan menjadi korban kejahatan termausk kekerasan seksual. Anak juga seringkali mendaoatkan perlakuan tidak wajar melalui eksploitasi di berbagai sektor. Studi ini bertujuan untuk menganalisis mengenai perlindungan anak sebagai korban kejahatan ekspolitasi seksual di Indonesia. Studi ini menggunakan pendekatan studi kriminologi dan viktimologi. Studi ini menemukan bahwa perlindungan hukum bagi anak telah diatur mulai dari Undang-Undang Hak Asasi Manusia, Undang-Undang Perlindungan Anak, hingga Undang-Undang Penghapusan Kekerasan dalam Rumah Tangga. Namun demikian, pada tataran implementasi, semua aturan hukum tersebut banyak menghadapi tantangan, salah satunya ketidakterbukaan informasi mengenai kasus yang ada.

Online transactions using the Cash On Delivery (COD) payment method play an important role in increasing the intensity of electronic transactions in Indonesia, this is because the COD payment method can reach consumers who do not have bank accounts or other digital wallets. The increase in the use of this payment method is inversely proportional to the public's perception of misguided understanding of the COD payment method, resulting in new problems such as consumers who are reluctant to pay for goods that have been ordered to protests accompanied by threats to delivery couriers. This paper aims to examine the weaknesses in COD transactions so that evaluations can be carried out in order to increase legal certainty for all parties. The type of research used is normative juridical using the statutory and conceptual approach. This study uses secondary data as the main data and uses library research as a material collection technique. All materials that have been collected are then inventoried, classified, and analyzed using descriptive analysis which aims to describe the problem so that innovative solutions are obtained. There are several shortcomings in this COD method, such as: buyer's misconception of the COD system, disinformation of goods with real conditions, and complicated methods of purchasing goods. This deficiency can be overcome in several scenarios, namely: strengthening legal protection for couriers delivering goods, using the principle of strict liability and reversing the burden of proof (reversion of the burden of proof) in the protection of E-Commerce consumers, and simplifying the rules for returning goods.

Increasing evidence has suggested alternative splicing (AS) is an essential mechanism for tumor initiation and progression. However, the functions of aberrant splicing have not been well understood in hormone therapy-treated breast cancer (HTBC) patients yet. By mining the SpliceSeq data of TCGA, we characterized 1388 survival-associated AS events (SASEs) that are markedly related to the overall survival (OS) of HTBC patients. Subsequently, a SASE prognostic signature was deduced via the least absolute shrinkage and selection operator (LASSO) and multivariate Cox analysis, and the HTBC patients were stratified into high- and low-risk groups based on the signature. The differentially expressed genes between the high- and low-risk patients were enriched with immune response genes. Furthermore, we revealed that B cell infiltration was significantly low in the high-risk patients with single-sample gene set enrichment analysis (ssGSEA), suggesting a link between AS abnormality and B cell infiltration in tumor immune microenvironment (TIME). Next, a similar prognostic signature based on splicing factor expression was deduced using Molecular Taxonomy of Breast Cancer (METABRIC) HTBC patients. When this prognostic signature was applied to stratify HTBC patients in the METABRIC and TCGA cohorts, the high-risk subgroups both had significantly low B cell infiltration in TIME. CIBERSORT analysis further demonstrated plasma cells infiltrated less in TIME. Also, both the AS (P  < 0.0001) and SF (P  = 0.009) prognostic signatures performed well in predicting OS of HTBC patients. In summary, our study has demonstrated that AS abnormality is a potential cause of B cell infiltration alteration, which is a critical factor for cancer death risks in HTBC patients and might be exploited therapeutically in the future.

This paper presents a confidential text documents leakage investigation system, focused on leak channels by documents printing and screen photographing. Internal intruders may print confidential document, take paper copy out of protected perimeter, make document image by scanner and perform anonymous leak. Also, intruders may take a photo of printed confidential document or displayed on workstation screen using personal mobile phone. Described leakage channels are weakly covered by traditional DLP systems that are usually used by enterprises for confidential information leak protection. Digital watermark (DWM) embedding is chosen as a document protection mechanism by implying changing of document image visual representation. In case of confidential document anonymous leak embedded DWM would enable the employee to determine what leak intentionally or by security protocol violation. System architecture consists of different type components. Employees’ workstation components provide DWM embedding into documents, which are sent for printing or displayed on screen. Information about watermark embedding is sent to a remote server that aggregates marking facts and provides it to security officer during investigation. Text document marking algorithms are developed, which embed DWM into printed and displayed on screen documents. Screen watermark is embedded into interline space interval, information is encoded by sequence of lightened and darkened spaces. DWM embedding into printed documents is implemented by three algorithms: horizontal and vertical shift based, font fragments brightness changing based. Algorithms testing methodology is developed in view of the production environment, that helped to evaluate the application area of algorithms. Besides, intruder model was formulated, system security was evaluated and determined possible attack vectors.

Published: February 2022

In this paper, we investigate the effectiveness of classical approaches of active learning in the problem of segmentation of document images in order to reduce the training sample. A modified approach to the selection of images for marking and subsequent training is presented. The results obtained through active learning are compared to transfer learning using fully labeled data. It also investigates how the subject area of the training set, on which the model is initialized for transfer learning, affects the subsequent additional training of the model.
The emergence of contrast structures for galactic magnetic field: theoretical estimates and modeling on GPU

Magnetic field generation in galaxies turns out to be a significant problem both for cosmic magnetohydrodynamics and mathematical physics. It is based on dynamo mechanism characterising the transition between the energy of medium turbulent motions and the magnetic field energy. The evolution of the field is described with the help of mean field dynamo equations. For galaxies the solutions are commonly found using so-called “no-z” approximation, while the half-thickness of the galactic disc is considered negligible. In nonlinear case mentioned equations admit contrast structure formation, predicted by the singular perturbation theory, describing equations with small parameter at the elder derivative. From astronomical point of view some authors tend to connect such solutions with the spiral structure of the galaxies and the formation of magnetic field reversals (when in different parts of galaxy there are regions with opposite directions of magnetic, divided by a thin transition layer). From numerical point of view finding the solution of two-dimensional system of equations requires large computational resources, for this reason using GPU and parallel calculations turns out to be reasonable. One of the implementation methods is calculating using OpenCL, which allows one to increase the process efficiency several times. OpenCL is a perspective crossplatform standard for development of applications, particularly involving GPU, the efficiency of which is rapidly increasing as the drivers evolve. The present work presents basic theoretical assessments of magnetic field behaviour, which are further confirmed and clarified during the computations. It is shown that the formation of the transition layers is described by fundamentally different mechanisms in radial and azimuthal directions. While radial reversals of the field turn out to be rather stable, all of the azimuthal structures are rapidly blurred due to the nature of the interstellar medium motions. That also indicates the practical impossibility of non-axisymmetric distributions of the field.

Se comparan los resultados de aprendizaje que obtienen 4.292 estudiantes de Educación Primaria, 32% en multigrado y 68% en unigrado, considerando asignaturas, tamaño del aula y ciclos. Es un estudio de campo, correlacional, explicativo y transversal que utiliza ANOVA y Análisis de Regresión Lineal Múltiple para el análisis de varianza. Los resultados indican que las agrupaciones multigrado, en contextos similares a las unigrado, pueden potenciar los resultados de aprendizaje en el segundo ciclo de Primaria y especialmente en matemática. El tamaño de las aulas parece tener alguna influencia; pero no afecta a todas las agrupaciones ni asignaturas de forma similar.
