Published: November 2022

Background
Several studies have explored the predictive performance of machine learning–based breast cancer risk prediction models and have shown controversial conclusions. Thus, the performance of the current machine learning–based breast cancer risk prediction models and their benefits and weakness need to be evaluated for the future development of feasible and efficient risk prediction models.

Objective
The aim of this review was to assess the performance and the clinical feasibility of the currently available machine learning–based breast cancer risk prediction models.

Methods
We searched for papers published until June 9, 2021, on machine learning–based breast cancer risk prediction models in PubMed, Embase, and Web of Science. Studies describing the development or validation models for predicting future breast cancer risk were included. The Prediction Model Risk of Bias Assessment Tool (PROBAST) was used to assess the risk of bias and the clinical applicability of the included studies. The pooled area under the curve (AUC) was calculated using the DerSimonian and Laird random-effects model.

Results
A total of 8 studies with 10 data sets were included. Neural network was the most common machine learning method for the development of breast cancer risk prediction models. The pooled AUC of the machine learning–based optimal risk prediction model reported in each study was 0.73 (95% CI 0.66-0.80; approximate 95% prediction interval 0.56-0.96), with a high level of heterogeneity between studies (Q=576.07, I2=98.44%; P<.001). The results of head-to-head comparison of the performance difference between the 2 types of models trained by the same data set showed that machine learning models had a slightly higher advantage than traditional risk factor–based models in predicting future breast cancer risk. The pooled AUC of the neural network–based risk prediction model was higher than that of the nonneural network–based optimal risk prediction model (0.71 vs 0.68, respectively). Subgroup analysis showed that the incorporation of imaging features in risk models resulted in a higher pooled AUC than the nonincorporation of imaging features in risk models (0.73 vs 0.61; Pheterogeneity=.001, respectively). The PROBAST analysis indicated that many machine learning models had high risk of bias and poorly reported calibration analysis.

Conclusions
Our review shows that the current machine learning–based breast cancer risk prediction models have some technical pitfalls and that their clinical feasibility and reliability are unsatisfactory.

Background
Acute coronary syndrome (ACS) is the most time-sensitive acute cardiac event that requires rapid dispatching and response. The medical priority dispatch system (MPDS), one of the most extensively used types of emergency dispatch systems, is hypothesized to provide better-quality prehospital emergency treatment. However, few studies have revealed the impact of MPDS use on the process of ACS care.

Objective
This study aimed to investigate whether the use of MPDS was associated with higher prehospital diagnosis accuracy and shorter prehospital delay for patients with ACS transferred by an emergency medical service (EMS), using a national database in China.

Methods
This retrospective analysis was based on an integrated database of China’s MPDS and hospital registry. From January 1, 2016, to December 31, 2020, EMS-treated ACS cases were divided into before MPDS and after MPDS groups in accordance with the MPDS launch time at each EMS center. The primary outcomes included diagnosis consistency between hospital admission and discharge, and prehospital delay. Multivariable logistic regression and propensity score–matching analysis were performed to compare outcomes between the 2 groups for total ACS and subtypes.

Results
A total of 9806 ACS cases (3561 before MPDS and 6245 after MPDS) treated by 43 EMS centers were included. The overall diagnosis consistency of the after MPDS group (Cohen κ=0.918, P<.001) was higher than that of the before MPDS group (Cohen κ=0.889, P<.001). After the use of the MPDS, the call-to-EMS arrival time was shortened in the matched ACS cases (20.0 vs 16.0 min, P<.001; adjusted difference: –1.67, 95% CI –2.33 to –1.02; P<.001) and in the subtype of ST-elevation myocardial infarction (adjusted difference: –3.81, 95% CI –4.63 to –2.98, P<.001), while the EMS arrival-to-door time (20.0 vs 20.0 min, P=.31) was not significantly different in all ACS cases and subtypes.

Conclusions
The optimized use of MPDS in China was associated with increased diagnosis consistency and a reduced call-to-EMS arrival time among EMS-treated patients with ACS. An emergency medical dispatch system should be designed specifically to fit into different prehospital modes in the EMS system on a regional basis.

Authors: Lê Văn Bình , Ngô Thị Thu Thảo 
Published: November 2022

Giai đoạn trưởng thành có thể phân biệt được các loài ốc thuộc họ Ampullariidae qua hình dạng bên ngoài và qua giải phẫu. Họ Ampullariidae có tỷ lệ giới tính không đều và ốc cái chiếm tỷ lệ cao hơn ốc đực trong quần đàn. Ốc đực và ốc cái phát triển giới tính riêng biệt, sau khi bắt cặp giao phối thì quá trình thụ tinh diễn ra trong buồng chứa tinh của con cái. Tập tính sinh sản chung là ốc cái đẻ trứng thành từng đám bám vào hốc đất, bùn hay trên thân cây thực vật thủy sinh. Ốc cái đẻ từng trứng hoặc từng đôi trứng, khi một cặp trứng đi ra khỏi đường sinh dục cái qua cơ quan đẻ trứng, sau đó được đẩy ra khỏi cơ thể và gắn vào cạnh dưới của tổ trứng, tổ trứng có nhiều tầng hay chỉ một tầng tùy thuộc vào nơi đẻ. Trứng ốc mới đẻ rất mềm, thường trong suốt và sau một thời gian được vôi hóa bởi một lớp canxi hạt trứng sẽ trở nên cứng chắc hơn. Màu sắc hạt trứng cũng khác nhau tùy theo loài ốc.

Published: November 2022

Belum adanya standar dalam mengelola Limbah dan standar pembuatan pupuk organik cair (POC) menjadi permasalahan yang belum terpecahkan bagi para petani bunga di kawasan Wisata Kopeng. Adanya standar tersebut akan berdampak pada efisiensi biaya produksi pupuk. Lokasi pendampingan berada di Kawasan Wisata bunga Kopeng, Kabupaten Semarang. Pendampingan ini dilaksanakan karena pengetahuan yang kurang dalam pemanfaatan limbah rumah tangga dan kurangnya pengetahuan dalam mengatur biaya produksi agar efisiens bagi para petani bunga Kopeng. Hal inilah yang menjadi pertimbangan untuk melakukan kegiatan tersebut. Beberapa Petani bunga di Kawasan ini tidak melakukan upaya penanganan saat membuang limbah rumah tangga. Tujuan yang ingin dicapai dari kegiatan pendampingan pembuatan pupuk organik (POC) dari limbah organik yang dihasilkan oleh rumah tangga adalah memberikan informasi pengetahuan serta menumbuhkan kesadaran masyarakat terhadap pentingnya pengolahan limbah secara efisien, sehingga para Petani bunga tidak sembarangan menumpuk sampah-sampah organik yang nantinya akan menimbulkan aroma tidak sedap sehingga mengundang penyebaran bibit penyakit. Selain itu adanya pengolahan limbah yang baik dapat menjadikan efisiensi pada biaya produksi yang pada akhirnya akan memberikan laba/ pendapatan yang optimal bagi para petani bunga di Kawasan Kopeng. Metode yang diterapkan dalam kegiatan ini adalah menyajikan materi kemudian melakukan Presentasi pada peserta pelatihan. Pendampingan masyarakat ini berhasil menumbuhkan kesadaran para petani akan pentingnya hidup sehat dan kreatif, memotivasi para petani agar tidak mendekati pestisida dan pupuk kimia dan beralih kepada pupuk organik cair (POC), serta melatih para peserta untuk belajar mengatur biaya produksi agar lebih efisien karena akan berdampak pada pendapatan/ laba yang akan mereka peroleh.

Hungarian Beyond the Border1 On the Contexts of Education, Bilingualism, and Labour Market in the Early 21st Century. The Transylvanian Perspective
Authors: Sorbán Angella 
Published: November 2022

Abstract
Borders are particular (in-between) spaces: they have this side and the other side, which involve several real and imaginary spaces at the same time. For minorities, “beyond the borders” is also a specific space of language use. This paper discusses the correlations between minority bilingualism and social structure characteristics based on sociological surveys, taking as approach the sociology of space and John Ogbu’s ecological cultural model of schooling. It aims to offer an overview of my research carried out on this topic and tries to provide some references for rethinking the sociological implications of minority education considering the experiences of three decades since the fall of communism in Romania. The main results of this research – in concordance with other findings of similar inquiries – show that a mother-tongue education for ethnic Hungarian children in Romania is a necessary but not sufficient condition for reducing the structural gap that Hungarians in Transylvania have inherited from the 20th century. This study is centred on the aspects of interrelation between the language of education and labour market, more specifically on those linked to the attitudes and patterns of behaviour towards the official language, with particular focus on the role that languages play in the society and, in a narrower sense, in self-positioning on the labour market.
“We were that small, special group in that large school with »normal« classes” Education in a Minority Language in the Context of Hungarians From Zagreb
Authors: Katalinić Kristina , Tamaskó Eszter 
Published: November 2022

Abstract
The latest research conducted in the Hungarian community of the City of Zagreb has shown that the Hungarian language is slowly losing its communication functions in informal domains (family, friends, the sphere of intimacy) and is withdrawing before Croatian, i.e., that language shift is in progress. As one of the key factors affecting language shift, school is mentioned as support in families in intergenerational language transmission and language preservation in the community. Croatia has ensured an institutional framework for education in minority languages to its minorities through a series of regulatory acts. However, exercising this right is often followed by numerous difficulties. In case of the Hungarian minority, this is due to geographical dispersity. Nevertheless, during the 1990s, a Hungarian group in kindergarten, a bilingual class and nurturing language for primary- and secondary-school pupils were launched in Zagreb. In order to obtain a clearer image of how various class models in a minority language actually function and which problems their participants are faced with, we conducted a preliminary research among younger members of the community who attended classes in Hungarian at least at one point during their education. We completed the results with information obtained through informal conversations with preschool and school teachers as well as through immediate observations of the community.
Building financial flexibility in preparation for Brexit: the case of Irish medium sized enterprises
Authors: McNamara Andrea , O’Connor Thomas , O’Donohoe Sheila 
Published: November 2022

Abstract
The purpose of this paper is to examine the building of financial flexibility by Irish medium sized enterprises in the run-up to Brexit. We analyze changes in firms’ dividends, leverage, cash, investment levels and working capital in the period surrounding the passing of the Brexit referendum to test for stockpiling of financial slack. Whilst we find no evidence of financial flexibility building overall, there is some evidence to suggest that firms incentivised to build such flexibility do so. Cash poor firms appear to build financial slack by way of reducing leverage and increasing their cash reserves. In contrast, cash rich firms increase their capital expenditure using internal and external funds. Interestingly all firms irrespective of their size or financial strength increase their working capital investment and in particular build their inventory levels post the Brexit referendum. Our evidence suggests Irish medium sized enterprises are optimistic of the opportunities post Brexit.
