The aim – to optimize the diagnosis of familial hypercholesterolemia (FH) in Ukraine and determine the prevalence of secondary dyslipidemia among people with «possible» FH.Materials and methods. The work was carried out in two stages of population research. At the I stage (2009–2013), in 81 out of 1000 respondents (8.1 %) the level of LDL-C ≥ 5 mmol/l was registered. At the II stage (2019), additional survey of respondents was conducted to identify secondary dyslipidemia.Results and discussion. After additional examination of respondents with «possible» FH on II stage, type 2 diabetes was diagnosed in 20.4 %, hypothyroidism – in 14.3 %, class II–III obesity – in 16.3 %. In 30.6 % of respondents, the understudied comorbid pathology was not detected, and the level of LDL-C decreased on the background of lifestyle modification and statin therapy. The «possible» FH was finally verified in 9 patients with a burdened anamnesis of early coronary artery disease in them and/or their first-degree relatives, as well as with an increased LDL-C and total cholesterol levels on II stage, despite statin therapy.Conclusions. The percent of respondents with «possible» FH on the I stage, based only on criteria of LDL-C ³ 5 mmol/l, was 8.1 %. But after the detection of secondary dyslipidemia, the prevalence of verified FH within urban population was 0.9 %. In the rest cases (80 %), the elevated level of LDL-C was associated with comorbid pathology. The study proves the need for further optimization of the managment of patients with impaired lipid profile to verify primary and secondary hypercholesterolemia.

Published: July 2021

Rendahnya pemahaman mahasiswa terhadap materi kuliah Mikrokontroler karena kurangnya peralatan dan modul praktek serta belum memiliki pemahaman konsep yang komprehensif terhadap mikrokontroler. Kuliah prasyarat mikroprosesor yang diambil pada semester sebelumnya belum dapat dipahami secara utuh dalam kehidupan praktis. Metode yang digunakan dalam pengembangan produk trainer dan modul adalah metode Research and Development (R&D). Pengembangan dari job sheet pertama praktek kontrol motor servo ini menggunakan kontrol manual tanpa recoording posisi pergerakan lengan robot yakni dengan menggunakan 4 (empat) buah motor servo, tahanan (potensiometer) dengan mikrokontroller arduino uno serta konstriksi lengan robot menggunakan bahan acrylic.Pengendalian robot lengan dengan kontrol motor servo dan miktokontroller arduino uno dapat dikendalikan berdasarkan variabel input perubahan dari nilai tahanan yang diberikan,setiap terjadi perubahan nilai tahan maka rotasi motor servo juga akan bergerak sesuai besar nilai tahan yang diberikan dan motor yang mampu bekerja dua arah (CW dan CCW). Arah dan sudut pergerakan rotor motor servo dapat dikendalikan dengan memberikan variasi lebar pulsa (duty cycle) sinyal PWM pada bagian pin kontrolnya. Sudut kerja motor servo dikendalikan oleh sebuah pulsa selebar ± 20 ms, dimana lebar pulsa high antara 0.5 ms dan 2 ms. Ketika motor servo yang diberikan pulsa sebesar 1.5 ms mencapai gerakan 90°, maka apabila diberikan pulsa kurang dari 1.5 ms maka posisi mendekati 0°, dan apabila diberikan pulsa lebih dari 1.5 ms maka posisi mendekati 180°. Berdasarkan perhitungan torsi yang diangkat setiap lengan untuk bagian Pitch (Bagian Pergelangan) = 0,22 kg.cm, Elbow (Bagian Siku) = 0,48 kg.cm, Shoulder (Bagian Bahu) = 0,3 kg.cm. Komunikasi interface antara aplikasi program pengendali dengan mikrokontroler Arduino Uno terjadi proses pengiriman (Tx) dan penerima (Rx) data serial yang berupa data byte. Pengembangan program terdiri dari tiga bagian, yakni bagian pertama merupakan kode program standart dari modul MT-100 Arduino, Pengembangan program robot lengan tanpa recoording dan pengembangan program dengan recoording. Sehingga diharapkan dengan adanya modul ini dapat menarik minat mahasiswa dalam mempelajari mata kuliah mikrokontroller dan minat mahasiswa dalam bidang robotika.
PENGARUH SUHU TERHADAP LAJU KOROSI BAJA KARBON RENDAH DALAM MEDIA AIR LAUT
Authors: Royani Ahmad 
Published: July 2021

Penggunaan baja karbon dalam pembangunan infrastruktur kawasan maritim dan lepas pantai sangat rentan terhadap kerusakan akibat korosi. Untuk mengetahui pengaruh suhu terhadap laju korosi dari baja karbon tersebut, maka dilakukan pengkajian korosi dengan metode Tafel polarisasi linear secara elektrokimia pada media air laut. Ekstraspolasi Tafel dilakukan pada berbagai suhu dengan mengubah potensial elektroda secara otomatis. Hasil laju korsi baja karbon rendah pada media air laut pada suhu ruang, 37 oC dan 50 oC masing-masing sebesar 5,54 mpy; 11,91mpy dan 14,53 mpy. Kenaikan suhu akan menyebabkan bertambahnya kecepatan reaksi dan mengakibatkan laju korosi menjadi meningkat. Selain faktor suhu larutan, korosi di media air laut juga dipengaruhi oleh kandungan oksigen terlarut, salinitas, pH dan total padatan terlarut.

Published: July 2021

Kontribusi bidang konstruksi terhadap kerusakan alam diantaranya berasal dari pengambilan material, proses pengolahan material, distribusi material, proses konstruksi, pengambilan lahan untuk bangunan serta konsumsi energi pada operasional bangunan. Selain menimbulkan kerusakan alam pada saat pengambilan material, kegiatan konstruksi juga menghasilkan limbah yang cukup banyak. Salah satu agenda yang banyak diperbincangkan untuk menanggulangi masalah global warming dan limbah konstruksi adalah melakukan promosi sustainable construction atau yang sering disebut sebagai konstruksi berkelanjutan. Dalam konsep green construction salah satu hal yang perlu diperhatikan adalah pengelolaan limbah atau waste management. Tujuan penelitian ini adalah mengetahui jenis dan kuantitas sisa material konstruksi dominan yang timbul di proyek konstruksi dan mengkaji dampak sisa material konstruksi dominan tersebut terhadap lingkungan. Sampel penelitian adalah consumable material proyek konstruksi gedung di kabupaten Badung. Metode yang digunakan untuk pengumpulan data adalah pengamatan lapangan, wawancara dan penyebaran kuisioner. Analisis data menggunakan analisis kuantitatif untuk mengetahui jenis dan kuantitas sisa material konstruksi dengan menghitung waste index dan wastage level.

Understanding Facebook’s Algorithm Could Change How You See Yourself
Authors: Papazoglou Alexis 
Published: July 2021

WHEN WE GO online these days, we know we’re not alone: The internet is looking back at us. Our clicks give us the information and products we ask for, but at the same time they provide information about us. Algorithms then make use of that data to curate our search results, our social media feeds, and the advertisements we see. The internet ascribes an identity to its users, and projects it back to us.
The research behind the political campaigns run by Cambridge Analytica in 2016 suggested that a few Facebook likes are enough for an algorithm to identify our gender, personality traits, sexual orientation, religious and political beliefs. “Computer-based personality judgments,” two psychologists and a computer scientist claimed in a research paper in 2015, can “be more accurate than those made by humans.” The algorithms can end up knowing us better than our spouses do. If that’s true—not all researchers think it is—what does that mean for our own understanding of who we are? …
Attention Is Not a Resource but a Way of Being Alive to the World
Authors: Nixon Dan 
Published: July 2021

‘WE ARE DROWNING in information, while starving for wisdom.’ Those were the words of the American biologist E O Wilson at the turn of the century. Fastforward to the smartphone era, and it’s easy to believe that our mental lives are now more fragmentary and scattered than ever. The ‘attention economy’ is a phrase that’s often used to make sense of what’s going on: it puts our attention as a limited resource at the centre of the informational ecosystem, with our various alerts and notifications locked in a constant battle to capture it.
That’s a helpful narrative in a world of information overload, and one in which our devices and apps are intentionally designed to get us hooked. Moreover, besides our own mental wellbeing, the attention economy offers a way of looking at some important social problems: from the worrying declines in measures of empathy through to the ‘weaponisation’ of social media.
How Much Can We Afford to Forget, if We Train Machines to Remember?
Authors: Tracy Gene 
Published: July 2021

WHEN I WAS a student, in the distant past when most computers were still huge mainframes, I had a friend whose PhD advisor insisted that he carry out a long and difficult atomic theory calculation by hand. This led to page after page of pencil scratches, full of mistakes, so my friend finally gave in to his frustration. He snuck into the computer lab one night and wrote a short code to perform the calculation. Then he laboriously copied the output by hand, and gave it to his professor.
Perfect, his advisor said—this shows you are a real physicist. The professor was never any the wiser about what had happened. While I’ve lost touch with my friend, I know many others who’ve gone on to forge successful careers in science without mastering the pencil-and-paper heroics of past generations.

The determinants of different types of R&D cooperation
Authors: Morandi Valentina 
Published: July 2021

- This paper provides new empirical evidence on the determinants of R&D cooperation by investigating the drivers of cooperation with different types of partners. Using data collected by the Third Italian Community Innovation Survey, this study estimates the influence of perceived obstacles to innovation, technological regime and market extension, a firm's absorptive capacity, appropriability conditions, partner selection capabilities, and management skills on the propensity to cooperate. The results of the multivariate analysis suggest a relatively stable set of R&D cooperation determinants, as well as some differences across cooperation types.

Investimenti diretti cinesi in Italia: da ruscello a fiume?
Authors: Stanca Lorenzo 
Published: July 2021

- Chinese outbound direct investments have experienced a strong increase in the last five years, spurred by the "Go Abroad" policy launched by the Chinese Government in 2002. Europe still ranks at the bottom of the list among the destinations of Chinese direct investments, but it is the fastest growing one. Within Europe, Italy is a late comer in attracting Chinese investments, but has been catching up quickly in the last few years. Investments have been made mostly in the logistics and in the manufacturing sector. In 2008 the acquisition of Cifa, a leading producer of cement-working machines, by Zoomlion signalled an important step in the history of Chinese investments in Italy. It is the largest Chinese acquisition in Europe so far and for the first time the Chinese investor is looking at integrating foreign management into its own managing structure. On average the size of Chinese companies investing in Italy is much larger than that of Italian companies looking at China for expansion. Furthermore, Chinese firms are focusing increasingly on manufacturing companies and are shunning those that do not appear in good shape. Acquiring a market share in Europe is the primary aim of Chinese companies investing in Italy, while the acquisition of technological skills plays a secondary role.

Diverse tipologie di venture capital e relazione tra investimenti e cash flow
Authors: Bertoni Fabio , Colombo Massimo G. , Croce Annalisa 
Published: July 2021

- In this paper we study the effect of venture capital (VC) financing on firms' investments in a longitudinal sample of 374 Italian unlisted new-technology-based firms (NTBFs) observed over the 10-year period from 1994 to 2003. In particular, we consider the influence of VC on both firms' investment levels and the sensitivity of investments to firms' cash flows. We also distinguish the effects of VC financing according to the type of investor: financial VC (FVC) investors and corporate VC (CVC) investors. We show that the investment rate of Italian NTBFs is strongly and positively correlated with their current cash flows. We also find that after receiving VC financing, NTBFs increase their investment rate independently of the type of VC investor. Even though, on average, VC financing seems not to affect the sensitivity of investments to cash flows, we have found that there is substantial heterogeneity according to the type of VC investor. In fact, CVC-backed firms still exhibit positive investment-cash flow sensitivity. Conversely, when firms receive VC financing from an FVC investor, the sensitivity of investments to cash flows disappears. Therefore, while this study clearly indicates that VC financing is beneficial to NTBFs, it also suggests that managers of NTBFs looking for external financing should be aware that the nature of these benefits depends crucially on the type of investor. .

Il disturbo di conversione ieri e oggi: evoluzioni teoricocliniche di un "simbolo" psicoanalitico
Authors: Silvestri Maura 
Published: July 2021

L'Autrice descrive le evoluzioni teorico-cliniche dei disturbi di conversione, assumendole come "simbolo" di un più ampio discorso che indirettamente permette di illuminare le profonde modificazioni intervenute negli ultimi anni nello sviluppo della nostra disciplina. Partendo dalle prime formulazioni di Freud, che si configurano come primo serio tentativo di spiegare "il misterioso salto dal mentale al fisico", l'autrice affronta poi il problema dell'inquadramento nosografico in ambito psicoanalitico e psichiatrico del processo "conversivo" con le relative aree di confusione terminologica che ancora oggi accompagnano l'uso di termini quali
. L'excursus storico si conclude con uno sguardo sul modo di concettualizzare i disturbi di conversione negli attuali orizzonti psicoanalitici, con particolare attenzione per la teoria del codice multiplo e per le profonde implicazioni del modello proposto dalla Bucci. La natura "enigmatica" e "densa" della tematica affrontata offre infine l'opportunità per una riflessione più generale sui cambiamenti avvenuti negli ultimi decenni nel modo stesso di approcciarsi all'antica e controversa problematica mente-corpo, e in particolare sulla tendenza attuale a superare la vecchia dicotomia e a considerarla, partendo da un vertice di osservazione sistemico, in un'ottica unitaria di mutua influenza circolare.
ON THE PROPERTIES AND APPLICATIONS OF A NEW EXTENSION OF EXPONENTIATED RAYLEIGH DISTRIBUTION
Authors: Abdulsalam Hussein , Abubakar Yahaya , Dikko Hussaini Garba 
Published: July 2021

Statistical distributions already in existence are not the most appropriate model that adequately describes real-life data such as those obtained from experimental investigations. Therefore, there are needs to come up with their extended forms to give substitutive adaptable models. By adopting the method of Transformed-Transformer family of distributions, an extension of Exponentiated Rayleigh distribution titled Gompertz- Exponentiated Rayleigh (GOM-ER) distribution was proposed and proved to be valid. Some properties of the new distribution including random number generator, quartiles, distribution of smallest and largest order statistics, reliability function, hazard rate function, cumulative or integrated hazard function, odds function, non-central moments, moment generating function, mean, variance and entropy measures were derived. Using the methods of maximum likelihood and maximum product of spacing, the four unknown parameters were estimated. Shapes of the hazard function depicts that GOM-ER is a distribution that is strictly increasing while those of the PDF depicts that GOM-ER can be skewed or symmetrical. Two datasets were fitted to determine the flexibility of GOM-ER. Simulation study evaluates the consistency, accuracy and unbiasedness of the GOM-ER parameter estimates obtained from the two frequentist estimation methods adopted.
A evolução do conflito dos estivadores portuários na Espanha
Authors: Ojeda Avilés Antonio 
Published: July 2021

O artigo trata da questão do trabalho portuário na Espanha, demonstrando os caminhos pelos quais tomaram rumo o conflito entre empregados e empregadores, potencializado, neste setor, pela interferência realizada pelo Estado, e, indiretamente, pela Comunidade Europeia. Por meio de uma análise crítica e de jurisprudência comunitária, o autor demonstra que as recentes alterações na legislação portuária causaram prejuízos à classe trabalhadora, retirando-lhe condições mais favoráveis anteriormente percebidas em atendimento aos clamores da liberalização dos portos, o que vai ao encontro da livre concorrência e do princípio da “maior atratividade”. Com isso, demonstra-se que a intervenção estatal espanhola na questão, por meio da edição de novos atos normativos, viola direitos previstos na Convenção 137 da OIT, ratificada pela Espanha, ao passo que sua edição é motivada pela intervenção do setor econômico na atividade pública, operacionalizada pelo governo conservador instalado no país em questão à época.
