Eating disorders between male and female adolescents with type 1 diabetes mellitus in Korea
Authors: Park Hye-Ryeon , Kim Na-Geong
Published: December 2022

Background: Diabetes mellitus and its prevalence are rising dramatically in Korea and throughout the world, not only in adults but in adolescents.
Objective: This study aimed to identify the sex-specific factors that influence eating disorders in adolescents with type 1 diabetes.
Methods: A secondary analysis of a descriptive survey was employed. Raw data from 136 adolescents aged 13 to 18 years who were diagnosed with type 1 diabetes were obtained in the original study using the Diabetes Eating Problem Survey-Revised (DEPS-R), Rosenberg Self-Esteem Scale (RSES), and Beck Depression Inventory-II(BDI-II). The data were analyzed using the independent t-test and multiple regression analysis.
Results: The female and male participants with eating disorders scored 21.67 ± 11.70 and 13.15 ± 8.03 points, respectively. Among the adolescents with type 1 diabetes, the factors related to eating disorders in female participants were body image satisfaction (β = 0.48, p <0.001) and depression (β = 0.22, p = 0.043), accounting for 33.4% of the variance. While the factors related to eating disorders in the male participants were BMI (β = 0.33, p = 0.006) and depression (β = 0.28, p = 0.017), accounting for 17.4% of the variance.
Conclusion: Sex-specific factors should be considered to induce healthy eating behavior in adolescents with type 1 diabetes and reduce eating disorders. Moreover, it is necessary for female adolescents to perceive their body type accurately, and male adolescents need exercise and nutrition education to lower their body mass index. Collaborations between medical practitioners, changes in the medical environment, and social interests are necessary. Since depression is the common factor associated with eating disorders in female and male adolescents with type 1 diabetes, a periodic depression screening test and intervention program that can lower depression should be developed. At the government level, it is necessary to strengthen economic support for cost interventions.

Background: The World Health Organization estimates that between 80,000 and 180,000 medical personnel perished as a result of COVID-19. Although studies about nurses’ organizational commitment during the COVID-19 pandemic have been conducted, the sources of motivations and resilience strategies of nurses in providing a quality healthcare service amidst the COVID-19 pandemic have yet to be explored.
Objective: This study aimed to investigate how motivation and resilience influence nurses to serve and cater to patients during the COVID-19 pandemic.    
Methods: A sequential exploratory mixed approach was used in this study between July and August 2022. The Connor-Davidson Resilience Scale (CD-RISC-10), Work Extrinsic and Intrinsic Motivations scale (WEIMS), and Garbee and Killacky’s Intent to Stay Scale (GKISS) were used to measure resilience, motivation, and intention to stay, among 50 nurses within Metro Manila. Quantitative data were analyzed using quantile regression, while qualitative data from eight participants were analyzed using thematic analysis.
Results: The majority of the nurses were working 12 hours and above (52%) and earning a bi-weekly income of PHP 15,001 to 20,000 (96%). The GKISS scores of most respondents indicated their likelihood of remaining in their current profession was moderately low (Mdn = 12.5; IQR = 12-14). It was also found that there was no sufficient statistical evidence to conclude that intention to stay was associated with resilience (p = 0.914) and work motivation (p = 0.560). The qualitative strand of this study explored the significant influences of motivation, resilience strategies, and sources of intention to stay among Filipino nurses while facing the COVID-19 pandemic. The primary motivations of nurses lie in family, passion for work, and career development, while the resilience strategies include adaptiveness, time management skills, and self-fulfillments. On the other hand, the intent to stay greatly lies in serving the people and the country.
Conclusion: This study concludes that positive and negative resilience and motivations from different facets of the social life of Filipino nurses, including passion, familial ties, patient care, and faith are the antecedents influencing the intention to serve in the healthcare service. In terms of staying for an extended period in a nursing career, the study found that institutionalized interventions, adequate compensation and benefits, and a good workplace are determinants of staying longer in the Philippines as Filipino nurses.
Variations on a theme: Labeling patients as persons, the nursed, or client in nursing
Authors: Betriana Feni , Locsin Rozzano C.
Published: December 2022

The debate regarding the variation of names used for labeling the patient in a nursing care situation has always existed in nursing. Names such as patient, client, person, and nursed have been used widely among healthcare disciplines, including nursing. However, does the use of any of these identifying terms establish the appropriate identification of the nurse and the persons being nursed in a nursing care situation participating in a mutual relationship? This editorial aims to address the varieties and rationales of identifying persons participating in or receiving nursing care. Among these terms, “person” describing human beings underscores personhood, allowing nurse-nursed relations to foster, support, celebrate, and affirm living the meaning of what matters most to one’s life. Therefore, it will be advantageous to nursing practice if the term “person being nursed” is the relevant descriptor to be considered as the primary label.
SPEAKING OBSTACLES ON ENGLISH FOR MEDICAL PURPOSE CLASS AT AN INDONESIAN COLLEGE OF HEALTH SCIENCES
Authors: Noprival Noprival
Published: December 2022

While a growing body of previous studies have addressed speaking a foreign language, very little research actually explores the speaking problems faced by medical students that speak English in Indonesian classrooms. To address this empirical gap, this research used a qualitative case study method to investigate the Indonesian pharmacy students' problems in speaking English during their English for medical purpose class. I conducted in-depth interviews to gather information from participants. An analysis of the interview data revealed that five major themes were related to students' speaking problems, including pronunciation challenge, anxiety, low self-esteem, poor grammar, and lack of vocabulary. The findings revealed that the sources of speaking problems reported by the interviewees were not only about language matters (i.e. vocabulary) but also the psychological ones (see anxiety). In addition, The results from this current research contribute to our understanding of the problems of speaking English in higher educational contexts that can be practically used as English class evaluation.

Authors: ТУСНИН Александр Романович , ПОСТАРНАК Михаил Валерьевич
Published: December 2022

Цель рассмотренного в статье исследования - определение возможности устройства мембранного перекрытия в многоэтажных зданиях со стальным каркасом. Предлагаемое новое конструктивное решение перекрытия направлено на повышение скорости монтажа, снижение материалоемкости и стоимости, что в целом представляет значительный научный и практический интерес. Для определения действительной работы мембранного перекрытия проведены испытания модели, мембранная часть которой выполнена из алюминиевого сплава. На модели размещались тензометрические датчики. Испытания проводились в четыре стадии. В результате были определены прогибы мембраны, напряжения в ней, перемещения опорного контура, изгибающий момент и т. д. Кроме того, был проведен численный расчет, который продемонстрировал качественно совпадающие с экспериментом данные. Результаты экспериментов и расчета показали работоспособность мембранного перекрытия с монолитной плитой, его высокую жесткость и несущую способность. Установлена малая чувствительность мембранного перекрытия к неравномерному нагружению.
Динамические эффекты в статически неопределимых физически и конструктивно нелинейных системах
Authors: КОЛЧУНОВ Виталий Иванович , ФЕДОРОВА Наталия Витальевна , САВИН Сергей Юрьевич
Published: December 2022

Приведены результаты расчетного анализа динамических эффектов, возникающих в статически неопределимых конструктивных системах из двухкомпонентных материалов типа железобетона, при хрупком разрушении бетонной матрицы, вызванном внезапным удалением из системы одного из несущих элементов. Показано, что динамическое догружение оставшихся неразрушенных элементов конструктивной системы зависит от ее топологии, степени статической неопределимости, процента армирования элементов. Живучесть железобетонной конструктивной системы при особом воздействии в виде гипотетического удаления из нее одного из несущих элементов предложено оценивать параметром внешней нагрузки, приложенной к системе в момент такого воздействия. На основе установленных закономерностей деформирования и разрушения, полученных анализом простейших систем, исследовано перераспределение силовых потоков в каркасах многоэтажных зданий при возникновении начального локального разрушения для различной топологии их конструктивных решений. Сделан вывод о том, что наибольшее влияние на снижение динамических эффектов и перераспределение усилий оказывают общая жесткость несущей системы и степень ее статической неопределимости.
Выбор рациональных параметров и топологии преднапряженных стальных рамных конструкций
Authors: АЛЕКСЕЙЦЕВ Анатолий Викторович , ДОМАРОВА Екатерина Владимировна
Published: December 2022

Предложен подход к выбору рациональных параметров и топологии систем предварительного напряжения металлических стержневых конструкций. Поиск по критерию минимизации стоимости осуществляется на дискретных множествах варьируемых переменных. При этом рассматриваются три частных постановки задачи. Первая предполагает фиксацию уровня преднапряжения и подбор профилей конструктивных элементов. Вторая постановка предусматривает возможность изменения положения системы преднапряжения на конструкции. Третья учитывает варьирование как усилия, создаваемого системой преднапряжения, так и ее расположение. В качестве инструмента для поиска рационального решения принят адаптированный генетический алгоритм. Использование генетического алгоритма предусматривает формирование наборов решений, которые улучшаются в процессе проверки на соответствие выбранному критерию оптимальности. Каждый элемент набора в генетическом алгоритме - это вариант конструкции с заданными параметрами и топологией системы преднапряжения. Работоспособность предлагаемых поисковых процедур подтверждена примерами проектирования рациональных для выбранных начальных условий преднапряженных рам с ферменным ригелем. При этом показано, что преднапряжение - эффективный способ получения несущих систем с минимальной стоимостью при варьировании параметрами конструкции, усилиями и геометрией ее преднапрягающих устройств.

Published: December 2022

В условиях эксплуатации наружные ограждающие конструкции зданий большую часть времени находятся под действием переменного теплового потока, обусловленного колебаниями температуры внешней среды и теплоносителя. При этом термическое сопротивление ограждающих конструкций на низких частотах колебаний теплового потока не остается постоянным. Приведены экспериментально-теоретические исследования влияния теплофизических параметров трехслойных монолитных ограждающих конструкций на изменение термического сопротивления в обычных условиях и при повышенной влажности. Для исследования использован метод аналогий по отношению к электрическим цепям. При составлении системы дифференциальных уравнений применена энергетическая цепь, учитывающая активные термические сопротивления и тепловые емкости каждого слоя ограждающей конструкции. Решение системы таких уравнений выполнялось частотным методом по разработанному алгоритму. Построены графические зависимости амплитудно-частотных характеристик, представляющие собой приращение модуля комплексного термического сопротивления, для четырех вариантов трехслойных монолитных панелей. Установлено, что при низкой частоте изменения теплового потока и температуры, приращение комплексного термического сопротивления ограждающей конструкции составляет от 1,42 до 5,68 % в зависимости от ее теплофизических свойств, при этом влажность материала также может оказывать влияние на термическое сопротивление.

По результатам лабораторных экспериментов определены параметры прочности и вязкости грунта. С использованием новой универсальной реологической модели А. З. Тер-Мартиросяна получены графики зависимости касательного напряжения от времени. В статье приводится сравнение экспериментальных кривых, полученных по результатам испытания на крутильный срез, и аналитических кривых, полученных на основании реологической модели.
Предложение о создании комиссии застройщика с целью корректировки проектно-сметной документации (В порядке обсуждения)
Authors: ЗЕЙНИЕВ Габил Ясинович
Published: December 2022

В статье представлен один из самых сложных этапов при вводе объекта в эксплуатацию - получение заключения о соответствии построенного сооружения требованиям проектной документации и технических регламентов. Выявлены и систематизированы проблемы, возникающие у застройщиков, которые характеризуются увеличением сроков ввода объектов в эксплуатацию и сопровождаются ростом финансовых и трудовых ресурсов. Наиболее сложной проблемой является прохождение повторной государственной экспертизы при несоответствии проектной документации, прошедшей первичную государственную экспертизу завершенного строительством объекта. Разработаны предложения, направленные на создание условий по сокращению сроков ввода в эксплуатацию объекта за счет исключения необходимости прохождения повторной государственной экспертизы. Обосновано создание функциональной схемы органа "Технический совет застройщика" на этапе ввода объектов в эксплуатацию для решения вопросов корректировки проектной документации. Выдвинутые предложения позволяют решить возникшие проблемы и помогают создать условия для сокращения сроков ввода объектов в эксплуатацию.

Pengembangan profesional perawat dalam tatanan pelayanan kesehatan menjadi unsur utama untuk meningkatkan mutu pelayanan serta meningkatkan kepuasan perawat dalam melakukan pekerjaan utamanya. Pengembangan profesional perawat ini juga dapat mencegah terjadinya burn out dan turn over perawat dalam suatu instansi pelayanan kesehatan. Penelitian bertujuan untuk mengetahui determinan pengembangan profesional perawat rumah sakit daerah. Penelitian ini menggunakan pendekatan cross-sectional. Pengambilan sampel menggunakan proportionate stratified random sampling dengan jumlah sampel 140 perawat. Pengumpulan data menggunakan Questionnaire-Professional Development for Nurses (Q-PDN), kuesioner Individual Career Management (ICM) dan kuesioner Organizational Career Management (OCM). Analisis data menggunakan Spearman’s rho dan uji regresi logistik berganda. Hasil menunjukkan sebagian besar manajemen karir individu dalam kategori rendah (52.1%), manajemen karir organisasi sebagian besar dalam kategori rendah (52.1%), dan pengembangan profesional perawat sebagian besar dalam kategori kurang (53,6%). Hasil uji statistik menunjukkan bahwa ada hubungan yang signifikan antara manajemen karir individu dengan pengembangan profesional perawat (p=0.000) dan manajemen karir organisasi dengan pengembangan profesional perawat (p=0.001). Hasil uji regresi logistik berganda menunjukkan bahwa faktor yang paling berpengaruh dalam pengembangan profesional perawat adalah faktor manajemen karir individu (p=0,003; Exp B= 3.039). Pembekalan melalui pendidikan dan pelatihan bagi perawat penting dilakukan untuk pengembangan profesional perawat.

Pemulung yaitu orang atau pekerja informal yang independen yang bekerja mengambil bahan/barang tidak terpakai yang terbuat dari plastik, kardus dan besi yang dapat dijual dan didaur ulang kembali. Risiko penularan penyakit pada pemulung lebih besar terjadi karena pekerjaannya berkaitan langsung dengan sampah. Penyakit berbasis lingkungan dapat berupa gangguan pada kulit yang disebabkan oleh bakteri, virus dan jamur. Tujuan dari penelitian ini untuk mengetahui faktor-faktor yang berhubungan dengan keluhan kulit pada pemulung di Tempat Pembuangan Akhir (TPA). Desain penelitian yang digunakan adalah cross-sectional. Populasi penelitian ini adalah seluruh pemulung di TPA Bangkonol Kabupaten Pandeglang. Sampel dalam penelitian ini sejumlah 120 pemulung, diambil dengan total sampling. Hasil penelitian menunjukkan ada hubungan antara personal hygiene (Pv=0,000), pengetahuan (Pv=0,000), ketersediaan informasi (Pv=0,000), dan masa kerja (Pv=0,000) dengan keluhan penyakit kulit. Sementara itu, tidak ada hubungan antara lama kontak (Pv=0,521) dengan keluhan penyakit kulit. Para pemulung sebaiknya lebih memperhatikan perilaku hidup bersih dan sehat, diantaranya dengan mencuci tangan sesudah dan sebelum bekerja, mandi dua kali sehari, memotong kuku dengan rutin (seminggu sekali), dan rutin mengganti pakaian kerja setiap hari.

The article provides information about the biofertilizer preparation "Fulfohumat "Ivan Ovsinsky"® and the results of its use against cotton wilt. When processing cotton with a preparation with a norm of 500 ml per hectare in the conditions of takyrovid soils of the southern regions of the Republic of Uzbekistan (Kashkadarya region), the incidence of cotton fusarium wilt decreases by 1.6 times, the efficiency is 83.9%, the number of dried plants decreases by 2.9 times, the weight of raw one box increases by 5.6%, the weight of 1000 seeds by 0.33% and fiber length by 1.5%. The yarn spinning coefficient has increased from a medium degree (130-140) to a high degree (140-149) or from a low degree (120-129) to a very high degree (150). The micronair of cotton fiber in treated plants has become softer — from 0.04 to 0.46 degrees. After treatment with the drug, the fibers in sick plants were lengthened by 0.016–0.018 inches, and in healthy plants the fiber length was shortened by 0.009 inches.

Background

Currently, studies have shown that a high dose of radiotherapy to the throat have various harmful and adverse effects on the patients’ laryngeal function, resulting in the development of pneumonia. This study aimed to explore how radiotherapy dose affected the probability of pneumonia following laryngeal cancer surgery.

Materials and methods

A retrospective analysis was done on patients diagnosed with laryngeal cancer between 2010 and 2020 and were treated surgically and with postoperative radiotherapy in the same institution. This study included 108 patients in total, 51 of who were in the low-dose group and 57 of whom were in the high-dose group. Age, gender, the location of laryngeal cancer, the presence or absence of lymph node metastasis, and other demographic and clinical characteristics were collected, and the prevalence of postoperative pneumonia was compared between the two groups.

Results

The total prevalence of postoperative pneumonia was 59.3%, but there was a significant difference between the two groups(high-dose group 71.9% VS low-dose group 45.1%; p=0.005). A total of 9.3% (10/108) of the patients had readmission due to severe pneumonia, and the rate of readmission due to pneumonia was significantly different between the two groups (high-dose group 15.8% VS low-dose group 2.0%, p=0.032). Additionally, the high-dose group’s prevalence of Dysphagia was significantly higher than the low-dose group’s. According to multivariate logistic modeling, high-dose radiation was a risk factor for pneumonia (OR=4.224, 95%CI =1.603-11.131, p=0.004).

Conclusion

Pneumonia risk could increase with radiotherapy doses > 50 Gy in the treatment of laryngeal cancer. Therefore, we recommend that when the radiation dose surpasses 50Gy, doctors should pay particular attention to the lung health of patients with laryngeal cancer.

In recent years, the development of computer technology has promoted the informatization and intelligentization of hospital management systems and thus produced a large amount of medical data. These medical data are valuable resources for research. We can obtain inducers and unknown symptoms that can help discover diseases and make earlier diagnoses. Hypertensive disorder in pregnancy (HDP) is a common obstetric complication in pregnant women, which has severe adverse effects on the life safety of pregnant women and fetuses. However, the early and mid-term symptoms of HDP are not obvious, and there is no effective solution for it except for terminating the pregnancy. Therefore, detecting and preventing HDP is of great importance. This study aims at the preprocessing of pregnancy examination data, which serves as a part of HDP prediction. We found that the problem of missing data has a large impact on HDP prediction. Unlike general data, pregnancy examination data have high dimension and a high missing rate, are in a time series, and often have many non-linear relations. Current methods are not able to process the data effectively. To this end, we propose an improved bi-LSTM-based missing value imputation approach. It combines traditional machine learning and bidirectional LSTM to deal with missing data of pregnancy examination data. Our missing value imputation method obtains a good effect and improves the accuracy of the later prediction of HDP using examination data.

This article is the third paper in a series aimed at the establishment of the authorship of Russian-language texts. This paper considers methods for determining the authorship of classical Russian literary texts, as well as fanfiction texts. The process of determining the author was first considered in the classical version of classification experiments using a closed set of authors, and experiments were also completed for a complicated modification of the problem using an open set of authors. The use of methods to identify the author of the text is justified by the conclusions about the effectiveness of the fastText and Support Vector Machine (SVM) methods with the selection of informative features discussed in our past studies. In the case of open attribution, the proposed methods are based on the author’s combination of fastText and One-Class SVM as well as statistical estimates of a vector’s similarity measures. The feature selection algorithm for a closed set of authors is chosen based on a comparison of five different selection methods, including the previously considered genetic algorithm as a baseline. The regularization-based algorithm (RbFS) was found to be the most efficient method, while methods based on a complete enumeration (FFS and SFS) are found to be ineffective for any set of authors. The accuracy of the RbFS and SVM methods in the case of classical literary texts averaged 83%, which outperforms other selection methods by 3 to 10% for an identical number of features, and the average accuracy of fastText was 84%. For the open attribution in cross-topic classification, the average accuracy of the method based on the combination of One-Class SVM with RbFS and fastText was 85%, and for in-group classification, it was 75 to 78%, depending on the group, which is the best result among the open attribution methods considered.

Nuclear power plant emergency robots are robots used to respond to significant public safety incidents, such as uncontrolled radioactive sources and nuclear catastrophe leaks. However, there are no standardized evaluation criteria for the optimal design of the robots. We offer a quantitative analytic algorithm for optimizing nuclear power plant emergency robots to address this issue. The method optimizes the structural parameters of the robot in accordance with the workspace by analyzing, comparing, and evaluating the workspace. The approach comprises constructing a kinematic model of the mechanical arm and proposing an optimization algorithm based on the alpha shape to accurately describe the manipulator workspace; employing the proposed convex hull algorithm to quantitatively analyze and evaluate the workspace generated by different solutions in terms of area, volume, task demand, Structural Length Index and Global Conditioning Index; and determining the robotic arm joint parameters by selecting the optimum workspace design solution. Using the suggested algorithm, we optimize the design of the master and slave robotic arms of the nuclear power plant emergency robots. Theoretical calculations and simulation results demonstrate that the method is an effective and practical evaluation technique that not only accurately describes the workspace but also optimizes the design of the nuclear power plant emergency robots.
