Thermal Conversion of Triazine-Based Covalent Organic Frameworks to Nitrogen-Doped Nanoporous Carbons and Their Capacitor Performance
Authors: Kim Gayoung , Shiraki Tomohiro , Fujigaya Tsuyohiko 
Published: January 2020

Abstract
Nanoporous carbons with well-defined pore structures are promising for advanced energy applications. Herein, we fabricate nitrogen-doped porous carbons via direct carbonization of a triazine-based covalent organic framework (TACOF1) that acts as both intrinsic template and carbon/nitrogen source. The carbonized TACOF1 forms porous carbon that has a large surface area (1194 m2 g−1) comprised of high volumes of micro- and meso-pores (0.58 cm3 g−1 and 0.44 cm3 g−1, respectively) with a narrow size distribution. In addition, nitrogen doping of the graphitic carbons is uniformly achieved. A thermal analysis along with evolved gas investigation reveals that chemical processes, including N2 gas release and graphitization, vary pore texture formation in the resultant carbons with strong dependence on carbonization temperature. Such structural difference of the carbonized TACOF1 changes electrochemical capacitor behavior. The carbonized TACOF1 synthesized at 800 °C is found to show good capacitive performance due to its nitrogen-doped porous structures.
Exercise and Nutrition Science Students’ Perceptions of Blogging as a Required Course Component
Authors: Halliday Tanya M. , Frisard Madlyn I. 
Published: January 2020

ABSTRACT
The growth of social media and websites for transmission of health-related information has increased in recent years, and development of online communication skills should be included in exercise science education. Incorporation of blogging into the higher education classroom may serve this professional development purpose, while also increasing student engagement and enhancing learning outcomes.

Purpose
The purposes of this study were to evaluate exercise and nutrition science students’ perceptions of blogging on perceived learning, sense of community, and technical knowledge at the beginning and end of the semester, and to compare the perceptions of undergraduate (UG) and graduate (GRAD) students.

Methods
UG (pre, n = 78; post, n = 50) and GRAD (pre, n = 20; post, n = 17) students were enrolled in semester long seminar courses that required blogging. Perceptions of blogging were assessed using an anonymous Likert-scale survey at the beginning and end of the semester. T-tests were used to determine differences in perception on the survey subscales pre to post and between UG and GRAD students.

Results
Agreement that blogging could enhance learning or promote a sense of community was lower at the end of the semester compared with the beginning, but remained relatively high. Agreement with items related to technical knowledge increased from presemester to postsemester. The change in perception in the whole sample was driven by the UG students, as GRAD students’ perceptions of blogging, although initially less positive than UG, were mainly unchanged from the start of the semester to the end.

Conclusions
Blogging as a required course component is viewed favorably by exercise and nutrition science students. Future research evaluating course characteristics and structure of blogging requirements that may enhance student’ perceptions are warranted.

Published: January 2020

Objective: To demonstrate that the use of platelet-rich plasma (PRP) enhances both the quality of healing and the time required for wound healing at a skin graft donor site. Methods: Patients who had dermo-epidermal skin grafts taken from the thigh area were included in a prospective, randomised clinical study. PRP was applied to one donor site and then covered with Vaseline-impregnated, open-weave gauze and gauze, while the contralateral donor site on the other thigh served as a control and was covered with the open-weave gauze and gauze without PRP. Results: A total of 24 patients took part in the study, of which three developed infections and were thus removed from the study. Use of PRP reduced the wound healing time of the dermo-epidermal graft donor sites by a mean 17.8% and median 18 days. On average, the treated donor sites healed in 14.9 days compared with 18.4 days for the control group. The median was 14 days compared with 18 days in the control group (p=0.026). In one patient, healing was slower on the side where PRP was applied. In 20 patients, healing of the donor site was accelerated where PRP was applied. Conclusion: The study demonstrated a beneficial effect of PRP, as healing time was shortened. Using PRP to heal wounds could be beneficial for patients for whom commonly available wound healing therapies have failed, as well as for high-risk patient groups for whom problematic wound healing may be expected.

Published: January 2020

Objective: Malignant wounds due to breast cancer can present with recurrent episodes of bleeding in the tumour tissue. This study will compare the efficacy of a calcium alginate dressing (Biatain, Coloplast A/S, Denmark) and a regenerated oxidised cellulose dressing (Surgicel, Ethicon, LLC, Puerto Rico). Protocol: A total of 24 patients with breast cancer and bleeding, malignant wounds will be enrolled in the randomised, controlled, open study, conducted at a hospital specialising in breast cancer treatment and at another hospital specialising in palliative care. Patients over 18 years old, with bleeding and willing to undergo venipuncture for blood collection will be included. All enrolled patients will be randomised for allocation to an experimental group (regenerated oxidised cellulose dressing) or a control group (calcium alginate dressing). The main intervention will consist of the application of the haemostatic product, assessment of digital pressure and estimation of the time required for haemostasis. Outcomes: Key outcome measures will be the percentage of patients with haemostasis within 20 minutes, observation of haemostasis after three, five and 10 minutes, in addition to recurrence of bleeding and the quantity of product used. Discussion: To our knowledge, this is the first study to evaluate the effectiveness of haemostatic products in malignant wounds. This type of wound is poorly explored in the literature and, among its signs and symptoms, bleeding is poorly studied. The completion of this study will provide a more robust rationale for clinical decision-making related to the control of bleeding in malignant breast cancer wounds in the context of evidence-based nursing practices.

Published: January 2020

OBJECTIVES:
Barrett's esophagus (BE) is the precursor lesion and a major risk factor for esophageal adenocarcinoma (EAC). Although patients with BE undergo routine endoscopic surveillance, current screening methodologies have proven ineffective at identifying individuals at risk of EAC. Since microRNAs (miRNAs) have potential diagnostic and prognostic value as disease biomarkers, we sought to identify an miRNA signature of BE and EAC.

METHODS:
High-throughput sequencing of miRNAs was performed on serum and tissue biopsies from 31 patients identified either as normal, gastroesophageal reflux disease (GERD), BE, BE with low-grade dysplasia (LGD), or EAC. Logistic regression modeling of miRNA profiles with Lasso regularization was used to identify discriminating miRNA. Quantitative reverse transcription polymerase chain reaction was used to validate changes in miRNA expression using 46 formalin-fixed, paraffin-embedded specimens obtained from normal, GERD, BE, BE with LGD or HGD, and EAC subjects.

RESULTS:
A 3-class predictive model was able to classify tissue samples into normal, GERD/BE, or LGD/EAC classes with an accuracy of 80%. Sixteen miRNAs were identified that predicted 1 of the 3 classes. Our analysis confirmed previous reports indicating that miR-29c-3p and miR-193b-5p expressions are altered in BE and EAC and identified miR-4485-5p as a novel biomarker of esophageal dysplasia. Quantitative reverse transcription polymerase chain reaction validated 11 of 16 discriminating miRNAs.

DISCUSSION:
Our data provide an miRNA signature of normal, precancerous, and cancerous tissue that may stratify patients at risk of progressing to EAC. We found that serum miRNAs have a limited ability to distinguish between disease states, thus limiting their potential utility in early disease detection.
«Искусственный интеллект», «онлайн-культура», «искусственная социальность»: определение понятий
Authors: Резаев Андрей Владимирович , Трегубова Наталья Дамировна 
Published: January 2020

В наши дни искусственный интеллект становится предметом пристального внимания и обсуждения в научно-технической среде, со стороны журналистов, политиков, бизнесменов и широкой общественности. Данная ситуация требует реакции представителей социального знания. Однако социальные ученые не спешат выходить на поле исследований искусственного интеллекта: это характерно для мировой науки в целом, и Россия не является здесь исключением. Таким образом, перед современной социальной аналитикой стоит задача прояснения теоретико-методологических оснований исследования искусственного интеллекта. Настоящая статья ставит цель внести вклад в решение именно этой проблемы. Авторы начинают с обсуждения теоретико-методологических затруднений, которые определяются в терминах проведения концептуального различения между искусственным интеллектом как феноменом, проблемой и понятием. Затем формулируются определения трех ключевых понятий: «искусственный интеллект», «онлайн-культура», «искусственная социальность»; авторы приглашают научное сообщество к дальнейшей дискуссии. В завершении статьи обсуждаются возможность перехода от абстрактных рассуждений к эмпирическим затруднениям и перспективы исследований искусственного интеллекта и искусственной социальности.

Ограничения при приеме на государственную гражданскую службу в РФ для молодых женщин (на основе эксперимента)
Authors: Уткина Валерия Владимировна , Гаспарян Сусанна Ашотовна 
Published: January 2020

Законодательство Российской Федерации наряду с международными нормативно-правовыми актами обеспечивает юридическую защиту женщин в общественных отношениях, однако традиционные представления о социальных ролях мужчин и женщин представляют собой препятствие к пользованию правами и свободами в полном объеме. Так, на государственной гражданской службе РФ, несмотря на предоставленные ч. 1 ст. 3 Трудового кодекса РФ гарантии, обеспечивающие соблюдение принципа гендерного равенства при трудоустройстве, претендентки молодого возраста сталкиваются с трудностями в процессе поступления.
В данной статье мы проверяем, готовы ли государственные учреждения нанимать беременных женщин или женщин с семейными обязанностями, а также молодых мужчин с семейными обязанностями. Для этого мы организовали и провели эксперимент — телефонный опрос контактных лиц по вакансиям, размещенным на сайте «Федеральный портал управленческих кадров», предоставляющих справочную информацию по вопросам поступления на государственную службу.
На основе эксперимента было выявлено воспроизведение гендерных стереотипов со стороны госслужащих, ответственных за коммуникацию с претендентами на замещение должностей государственной гражданской службы. «Штраф за материнство» молодые женщины получают еще на этапе поступления на работу в органы государственной власти в условиях «доминирующей маскулинности».

Definicja i granice prawnej ochrony prywatności w epoce analityki big data
Authors: Rojszczak Marcin 
Published: January 2020

Po ponad stu latach od wprowadzenia pierwszych definicji prawa do prywatności treść tego prawa i tym samym granice jego ochrony są wciąż analizowane i dyskutowane w doktrynie. W systemach ochrony praw człowieka dominuje podejście do definiowania prywatności przez wprowadzanie katalogu chronionych wartości. Jednocześnie w prawie ochrony danych zakres regulacji wyznaczany jest terminami „dane osobowe” i „specjalne kategorie danych”. Definicja tych pojęć jest stosowana w niemal niezmienionej formie od ponad trzydziestu lat. Podział zagrożeń dla prywatności na wertykalne i horyzontalne nie jest aktualny w odniesieniu do zdarzeń zachodzących w cyberprzestrzeni. Działania organów publicznych i wyspecjalizowanych podmiotów, takich jak brokerów danych, w coraz większym stopniu się uzupełniają. Gromadzenie ogromnej ilości danych na temat setek milionów użytkowników może prowadzić do naruszenia prywatności nie tylko jednostek, lecz także całych społeczeństw. Celem niniejszego artykułu jest próba analizy, czy obowiązujące przepisy prawne bazujące na koncepcjach ukształtowanych w erze przedinternetowej posiadają potencjał do skutecznej ochrony przed zagrożeniami związanymi z nowoczesnymi formami przetwarzania danych, takimi jak big data. W tym celu omówiono najważniejsze cechy big data, takie jak algorytmiczne budowanie wniosków czy efekt przyrostowy, a także wyjaśniono, w jaki sposób technologia ta pozwala na omijanie ograniczeń prawnych związanych z przetwarzaniem różnych kategorii danych osobowych. W podsumowaniu sformułowano postulat opracowania przepisów dotyczących regulacji rynku przetwarzania dużych zbiorów danych.

Published: January 2020

AbstractIn this paper, a method for evaluating the chronological age of adolescents on the basis of their voice signal is presented. For every examined child, the vowels a, e, i, o and u were recorded in extended phonation. Sixty voice parameters were extracted from each recording. Voice recordings were supplemented with height measurement in order to check if it could improve the accuracy of the proposed solution. Predictor selection was performed using the LASSO (least absolute shrinkage and selection operator) algorithm. For age estimation, the random forest (RF) for regression method was employed and it was tested using a 10-fold cross-validation. The lowest absolute error (0.37 year ± 0.28) was obtained for boys only when all selected features were included into prediction. In all cases, the achieved accuracy was higher for boys than for girls, which results from the fact that the change of voice with age is larger for men than for women. The achieved results suggest that the presented approach can be employed for accurate age estimation during rapid development in children.
