Published: December 2022

Due to the intensity of marina activities and global climate change, marinas are facing the challenge of sustainability. Therefore, the concept of “green port” has now become a requirement. In practice, the term “green port” describes the activities of all stakeholders involved in the port business towards a sustainable development of the port. This paper aims to provide an insight into the current application of sustainability principles and the concept of “green port” in Croatian marinas. Therefore, the concept of “green port” is described. Furthermore, the framework (regulations, policies, international and national certificates and programs) for sustainable activities in Croatian marinas are analyzed. The main part of the paper is the analysis of sustainable activities, i.e. practices in Croatian marinas related to eco-spatial design, standardization and awarding system, energy transition, sustainable waste, water and air systems. Therefore, positive sustainable practices in selected Croatian marinas and aspects that need improvement are identified.

Rework in Car Series Production through the Lens of Knowledge Work: A Case Study
Authors: Juhart Kathrin , Pammer-Schindler Viktoria
Published: December 2022

Rework in car series production are all activities that aim to detect, analyze and eliminate errors in cars and preceding production systems. In the present paper, we describe and analyze rework from the perspective of knowledge work. The described case is set within a global car manufacturing company. Data were collected in contextual inquiries and analyzed by the collective elaboration of notes and models, resulting in structured descriptions of work practices and consolidated contextual design models. Based thereon, we discuss that in particular the core rework activity of analyzing errors, their causes, and eliminating systematic errors (error treatment) is knowledge-intensive. Error treatment is also highly collaborative, as it involves many stakeholders, and complex systematics of communication between them. In particularly complex cases, error treatment can even be considered wicked problems, for which no clear-cut solution exists. In parallel to this, error treatment is not digitally supported, except systems for documentation and reporting. CSCW, with its long tradition of research in knowledge and expertise sharing, can therefore contribute to potential digital support. At the same time, CSCW research is called upon to update and newly contextualize its knowledge in the field of work practice in modern manufacturing. More broadly, we conclude that error treatment includes core activities in the face of complex, semi-automated systems, which are not easy to automate at all. Hence, the present case study constitutes a detailed description and analysis of error treatment as type of activity that will become more significant and widespread in the future.

Risk compensation: how vaccination impacts social distancing in an online natural experiment
Authors: Patel Krishane
Published: December 2022

To reduce transmission of COVID-19, public mandates recommended or required minimum physical distancing between individuals, in addition to the use of vaccine rollouts as a public health measure. When individuals are faced with multiple risk reducing behaviours, they may engage in risk compensation. In an online natural experiment, risk compensation was investigated during the COVID-19 pandemic to examine whether vaccination and beliefs in vaccine efficacy reduced physical distancing. Participants completed a distance matching task, where they position avatars of themselves in hypothetical stylized images of everday scenarios in a 2 (location) x 3 (activity) factorial design. Consistent with risk compensation, this study finds that individuals are more willing to stand closer to strangers when fully vaccinated as vaccine beliefs grow. Furthermore, such behaviours do not mitigate when controlling for percieved risk of a COVID-19 infection or hospitalisation. A similar finding is observed for vaccine intentions as well as a difference between revealed and stated preferences of risk when comparing across vaccine manufacturers. These results suggest that though vaccines can be effective as a public health measure, the act of being vaccinated may lead to risk compensation that could lead to additional waves from mutations of any such public health crisis.
Is minority stress the cause of poor mental health in sexual minorities?
Authors: Ujma Péter Przemyslaw
Published: December 2022

Sexual minorities suffer from worse than average mental health. The most widespread explanation of this phenomenon is minority stress theory, which attributes poor mental health to stigmatization and discrimination by the rest of society. In my review I argue that minority stress theory is not a sufficient explanation of poor mental health in sexual minorities. My arguments are based on four observations: 1) other social groups which experience or historically experienced discrimination do not suffer from poor mental health, 2) sexual minorities suffer from worse than average mental health even when they experience a low level of discrimination, 3) the quasi-experimental studies best suited to support this theory suffer from serious methodological errors, 4) genetic-biometric studies do not or only partially support the hypothesis that sexual minority status (through discrimination or other mechanisms) is causal to poor mental health. Alternative theories are necessary to explain the etiology of mental health problems in sexual minorities.
Effect of change in pelvic tilt angle on neck muscle activity in sitting posture
Authors:   The Korean Society of Medicine & Therapy Science, Kim Su-Min , Park Jun-Hyung
Published: December 2022

Objective: Pelvic tilt should be used to examine muscle activity in the neck and shoulders. Method: The neck muscle activity was measured during an anterior pelvic tilt in a random order for 30 selected subjects, and the neck muscle activity was measured during a posterior pelvic tilt after 1 minute of rest. Results: The %RVC values of upper trapezius, SCM, and SC were significantly lower in the anterior pelvic tilt than in the posterior pelvic tilt. Conclusion: The anterior pelvic sitting posture prevents forward posture by maintaining the normal curvature of the spine and relatively reduces the load around the neck and shoulders. Therefore, in order to correct the forward posture, it seems appropriate to perform the anterior tilt of the pelvis in advance.

Style Queen Kebaya Store (SQ Kebaya) is a store that is engaged in apparel, its product sales focus includes adult and children's kebaya. The negative impact of the Covid 19 Pandemic has proven that the Store (SQ Kebaya) has experienced a decline in sales turnover in 2020, therefore the SQ Kebaya Store's efforts to restore its sales activities are by giving gifts for customer appreciation during the COVID 19 season through selecting the best customers for the 2020 period. However, the problem faced by SQ Kebaya Stores in the process of evaluating the best customer selection is that there is no criterion weight so that the decision making is not right on target, making the best customer decisions less efficient because they have to look for customer sales records manually in the sales record book. This study produces a web-based decision support system for selecting the best customers at SQ Kebaya Stores using the AHP (criteria weight), SAW and WASPAS (best customer ranking) methods, this study produces priority weights and importance levels of each criterion, namely status (0.37 ), method of payment (0.23), total spending (0.14), quantity (0.13), intensity of visits (0.07), length of subscription (0.07) and the result of ranking the percentage of the largest alternative value is the alternative SAW method with an average of 0.6952 , while the WASPAS method is 0.6405. It can be concluded that the right method used to obtain the best alternative value is the SAW method.

Published: December 2022

Tumor necrosis factor-alpha (TNF-α) antagonists’ therapy are expensive and has a non-responsive rate between 30% to 40% in rheumatoid arthritis patients. Genetic variation plays a vital role in the responsiveness to this type of therapy.The aim of this study is to investigate if the presence of genetic polymorphism in the TNF-α gene promoter region at locations -376 G/A (rs1800750), -806 C/T (rs4248158), and -1031 T/C (rs1799964) affects rheumatoid arthritis patient's tendency to be a non-responder to etanercept.
Eighty RA patients on etanercept (ETN) for at least six months were recruited from the Rheumatology Unit at Baghdad Teaching Hospital. Based on The European League Against Rheumatism response (EULAR) criteria, patients were divided into two groups: responders and non-responders. After polymerase chain reaction amplification of their DNA, the amplified DNA was sequenced by Sanger method to determine the polymorphisms at the positions -376G/A, -806 C/T, and -1031T/C.
The results of this study found that equally Phi correlation and binary logistic regression analysis revealed a non-significant association for all genotypes in the three polymorphic sites with the tendency for being non-responder. Moreover, there was no significant difference in TNF-α mean level or the change in disease activity score for 28 joints (DAS28) after six months of etanercept therapy between all genotypes for each polymorphic site.
The present study concludes that there was no correlation between the polymorphisms in the TNF-α promoter region at -376G/A, -806 C/T, and -1031T/C with the tendency for being non-responder to ETN.

Organgel has an excellent viscoelastic properties, floating system posses a depot property.  Different formulations of 12-hydroxyoctadecanoic acid (HOA) in sesame oil were gelled and selecting F1, F3 and F5 HOA organogels for various examinations: tabletop rheology, optical microscopy, and oscillatory rheology studies. Also, the floating properties studies were conducted at in vitro and in-vivo levels. Lastly, the in-vitro release study using cinnarizine (CN) was to investigate the organogel depot property. Based on the results, the selected concentrations of HOA in sesame oil organogels showed temperature transitions from gel to sol higher than body temperature. These organogels scaffolds inner structures were a star-like shape. The formulation F5 HOA/SO organogels were developing higher storage modulus values, which resulted from the amplitude sweep study. Indeed, all the selected organogels were frequency sweep independent. The organogel’s in vitro floating properties were found positively proven our work’s aim and were buoyant for 24 hours as F5 HOA organogels remained for 12 hours in the rat’s stomach. The depot property showed the slow release of CN from F5 HOA/SO organogel and not more than 65% w/w of CN released after 24 hours.

Published: December 2022

The most prevalent chronic complication of diabetes mellitus is diabetic neuropathy. The pathogenesis of diabetic neuropathy is exacerbated by hyperglycemia-induced oxidative stress, which causes nerves to deteriorate in a programmed manner. Many clinical trials depend on supplement in an attempt to improve neuropathy symptoms such as (pain & tingling) and patient quality of life, one of them is Coenzyme Q10 which is reported to have an anti-inflammatory and antioxidant effects, and was totally nontoxic and non-reported side effects. This study aimed to evaluate using a Coenzyme Q10 supplement as an adjuvant therapy to gabapentin to improve the clinical symptoms of diabetic neuropathy in relation to its anti-inflammatory and antioxidant effects. This open-label interventional study involved 33 diabetic neuropathy patients divided into two groups: group (1) 16 patients were given 300 mg of gabapentin once a day at evening, plus group (2) 17 patients received 300 mg of gabapentin once a day in the evening plus Coenzyme Q10 200mg once daily. Pre- and post-3 months of treatment, blood samples used to measure metabolic, anti-inflammatory and antioxidant biomarkers (fasting blood glucose, glycated hemoglobin, tumor necrosis factor-α, Iinterleukin-6 & Superoxide dismutase) , as well as the Michigan neuropathy screening instrument for  assessment of clinical symptoms. After 3 months of Coenzyme Q10 use, the results showed that the group 2 produced a highly significant change in glycated hemoglobin & fasting blood glucose levels. Meanwhile, there is no significant change in glycated hemoglobin & fasting blood glucose values in patients receiving just gabapentin. Moreover, results showed highly significant differences in Michigan neuropathy screening instrument, tumor necrosis factor-α, iinterleukin-6 & superoxide dismutase between the study groups at the completion of the research. Finally, addition of Coenzyme Q10 to gabapentin for diabetic neuropathy patients result in improving the glycemic control & symptoms of the diabetic neuropathy, as well as decreasing effects of the inflammation in addition to oxidative stress after three months of treatment.

Published: December 2022

New substituted anthraquinones with amino derivations fragments were synthesized through the substitution of bromine atom by different amines using the Ullmann coupling reaction. Obtained compounds based on anthraquinone used for experimental antimicrobial studies. The structure of the synthesized compounds was confirmed by LC-MS and 1H, 13C NMR spectroscopy. Studies on planktonic microorganisms have shown that the first synthesized anthraquinone derivatives have an inhibitory effect against bacteria and fungi. The triazene 1-(3-(benzoic acid(triaz-1-en-1-ol(-4-(1H-imidazol-1-yl(-9,10-dioxo-9,10-dihydroanthracene -2-sulfonic acid, have wide spectrum of activity, growth retardation zones against gram-positive microorganisms in the range of 8.41-11.5 mm, gram-negative bacteria 5.87-8.18 mm, fungi of the genus Candida 5.81-7.48 mm. The high antimicrobial activity of this compound is probably due to the presence of benzoic acid in its molecule.

Statistical Model for Excitation and Hypersynchronization in the Small Neural Populations
Authors: BORİSENOK Sergey
Published: December 2022

The mathematical modeling of epileptic seizures appearing in small neural populations can follow a few alternative ways: modeling of individual cells and their interaction vs. modeling groups and clusters on neurons. The purpose of this work is invention of a novel continuous (population-based) model for the appearance of the hyper-synchronized firing cells of the epileptiform type. In the same time, we use here the master equations based on the transition probabilities among different states of the cell excitation and hyper-synchronization. We developed an ODE model combining the dynamical equations for different sub-populations (unexcited, excited, and, as our novelty, hypersynchronized). Our model may serve as a simple but powerful tool to analyze the appearance and development of epileptiform dynamics in artificial neural networks. It can cover different cases of microepilepsy, and also may open the gate for studying drug-resistant epilepsy regime. Our dynamical set can be extended with the control inputs mimicking the external perturbations of the neural clusters with the electrical or optogenetic signals. In this case, the set of control algorithms can be applied to detect and suppress the epileptiform dynamics. Thus, the dynamic processes of epilepsy in small neural populations do not demand necessary the development of detailed models for individual neurons. Even the ‘averaged’ dynamical set for the unexcited, excited and hypersynchronized sub-populations can serve as an efficient tool for investigation and numerical simulations of microscopic seizures.

İkinci öznitelik, orijinal ismiyle Scale Invariant Feature Transform (SIFT), veya Türkçe’deki karşılığı ile Ölçek Değişmez Unsur Dönüşümü, yine nesne tespitinde ve nesne tanımada çok sık kullanılan bir başka özniteliktir. Bu iki öznitelikten birisinin çıktısını herhangi bir sınıflandırıcıya girerek oldukça başarılı sonuçlar almak mümkündür. Peki sınıflandırıcıdan bağımsız olarak hangi öznitelik daha iyi sınıflandırma performansı vermeye yatkındır? Bu çalışmada bu soru cevaplanmaya çalışılmıştır. Veri olarak VisDrone veri setinden araba ve yaya sınıflarından 10’ar tane görüntü kullanılmıştır. Bu iki sınıftan örnek görüntülerin sınıf içi ve sınıflar arası ortalama uzaklıkları hesaplanmış ve sonuçlar raporlanmıştır. Fisher’in Ayırtacına benzer bir mantık ile bir performans metriği hesaplanmıştır. Elde edilen sonuçlardan HOG özniteliğinin sınıflandırıcıdan bağımsız olarak bu örnek veri setinde sınıflandırma için daha uygun bir öznitelik olduğu tahminine varılmıştır.

Вступ. Населення України часто скар­житься на втому, що призводить до зни­ження працездатності. Стресові ситуації зумовлені зазвичай високим темпом життя громадян, технологічним прогресом, малорух­ливістю, довготривалою роботою за комп’ю­тером та шкідливими звичками (паління, алкоголь). Наразі воєнні дії в нашій країні, енергетична криза, інші непрогнозовані фак­тори впливу внаслідок повномасштабного вторг­нення ро­сій­ської федерації значно загос­трюють зазна­чену проблему. Проблема. Тривалість активної фізич­ної працездатності може бути неочікувано мала внаслідок втоми, яка швидко настає і накопичується та трансформується у хро­нічну, що саме і призводить до зниження фізичної працездатності. Тому питання класи­фікації препаратів, які застосовуються для її підвищення, та дослідження асортименту лікар­ських засобів для стимуляції фізичної праце­здатності, представлених на фармацевтич­ному ринку України, є актуальним питанням. Метою статті є аналіз асортименту лікар­ських засобів на фармацевтичному ринку України для підвищення фізичної працездат­ності населення. Методи. Для аналізу доказової інформа­ції використовували методи роботи, як-от систематичний огляд та соціологічний (на основі анонімного анкетування фармацев­тичних працівників з’ясовували частоту від­пуску препаратів для підвищення фізичної працездатності). Результати дослідження. На пiдставi анонімного анкетування фармацевтичних пра­цівників з приводу частоти відпуску препа­ратів для підвищення фізичної працездатності нами зафіксовано засоби, які найчастiше вико­ристовуються для лiкування цього стану. Зважаючи на те, що в Україні використо­вується загальноприйнята у світі АТС-кла­сифікація, проведено визначення АТС-коду та відповідної до АТС-класифікації групи пре­паратів для стимуляції фізичної працездат­ності та проаналізовано класифікацію препа­ратів, які застосовуються для підвищення фізичної працездатності. Висновки. Аналіз асортименту засобів для підвищення фізичної працездатності на фармацевтичному ринку України за останнi два роки показав, що обрані засоби пред­став­лені 44 торговими назвами на основі 13 міжнародних назв. Достатній асортимент препаратів для підвищення фізичної працездатності надає широкі можливості пацієнтам та лікарям у виборі адекватної фармакологічної корекції захворювань і оптимізації індивідуального вибору препаратів.

Introduction. The emigration of more than 5.5 million citizens of working age and the inter­nal displacement of more than 7.7 million Ukrai­nians after the start of the full-scale war with Russia caused changes in the HoReCa labor market. Problem. The portrait of an employee in the HoReCa sector in Ukraine and abroad has chan­ged significantly. Therefore, the study of the state of the labor market in the field of restaurant industry in wartime conditions is relevant. The aim of the work is to carry out a compre­hensive analysis of the Ukrainian labor market state in the field of restaurant business in war conditions, to determine the main trends and pro­spects for further development. Methods. General scientific methods of ana­lysis and synthesis, comparison, isolation, gene­ralization and resulting systematization of the researched material are applied. Results. As a result of the war there was a decrease in the market potential of the restaurant business. Consequently, the labor market changed its orientation from the employee to the employer. Candidates are forced to give in to salary interests and adapt to new realities of work. The number of line workers is reduced as much as possible, resulting in an increase in the number of responsibilities of the rest of the staff. The Ukrainian restaurant business market suffers from a lack of qualified personnel, some of whom are mobilized, belong to IDPs or refugees. The labor market potential of the restaurant business abroad is analyzed. As a result, a port­rait of a potential employee in the wartime res­taurant business is described. Conclusions. There will be a significant per­sonnel update, we will have to reckon with changes in the portrait of a potential employee, and these circumstances will have a negative impact on business in general. While the Ukrai­nian restaurant market is undergoing structural changes, nothing will fundamentally change abroad.
Front-of-pack labelling of food products: international practices and perspectives

Introduction. A prerequisite for the deve­lopment of the food market is to provide con­sumers with accessible and necessary informa­tion about properties of food products. Food products labeling on the front of the package is aimed at facilitating consumers’ understanding of information about their usefulness. Problem. A wide range of symbols, schemes and formats have been developed which would provide information about the properties of food products to the consumer in the most convenient and accessible form. However, it is important to analyze the existing options and the effecti­veness of this method of informing consumers about the usefulness of food products. The aim of the work is to analyze different approaches to food products labeling on the front of the package in terms of their informativeness and usefulness for consumers. Methods. The methods of comparative ana­lysis and synthesis, selection and generalization, legislative and regulatory documents were used. Results. Many front-of-pack labeling sys­tems are known today, including Multiple Traffic Lights, Reference Intakes, Health Star Rating system, Nutri-Score, etc. Each of these systems has its own peculiarities regarding the content and way of presenting information about the components of the product, in terms of their use­fulness for the human body and the presence / absence of components that may have a negative impact on health. However, the current labeling systems make it possible to compare food products without taking into account other aspects of health im­pact (degree of processing, added additives that make them unhealthy), which does not allow to provide a complete profile of the health benefits of the food product. Conclusions. The analysis of different front-of-pack nutrition labels systems proved that thanks to such information, consumers have the opportunity to choose more healthy food products. The adoption and implementation of a single label on the front of the package can be useful for consumers and reduce the number of cases associated with the negative impact of food products on health.

Вступ. Характеристики подушок визна­чаються функціональними, тобто спожив­чими властивостями, що зумовлюють їх вико­ристання за призначенням як предмета спо­живання. А оскільки призначенням пос­тіль­них виробів, зокрема подушок, є забез­пе­чення комфортного сну людини, то функ­ціо­нальні властивості є найважливішими. Проблема. Формування асортименту поду­шок вказує на необхідність дослідження їхніх функціональних властивостей, у т. ч. доско­налості виконання основної функції, тобто критерію м’якості – жорсткості. Метою статті є дослідження функціональ­них властивостей подушок для сну, зокрема розрахунок критерію м’якості – жорсткості. Методи. Ступінь м’якості – жорсткості подушок оцінено за стандартизованими показ­никами: міцністю і масою наповнювачів, а також висотою подушок під час наванта­ження та без навантаження. Дослідження про­ведено на виробничому підприємстві ТОВ "Герд Біл­лербек ГмбХ" (Україна). Результати дослідження. Розрахунок кри­терію м’якості – жорсткості подушок здій­снено за коефіцієнтом поверхневої густини пір’яно-пухових, вовняних та синтетичних наповнювачів. Поділ зроблено на категорії: м’яка; середньої жорсткості; жорстка. За проведеними експериментальними дослі­дженнями висоти подушки з різним типом наповнювача без навантаження та після наван­таження визначено, що саме міцність напов­нювача безпосередньо впливає на зміну фор­ми подушки під час експлуатації. Висновки. Експериментально встановлено, що значення критерію м’якості – жорст­кості подушки безпосередньо залежить від показника висоти виробу без та після наван­таження, оскільки подушка може мати значну усадку під час сну або, навпаки, зберігати свою висоту. Рекомендовано в нормативній, торго­вель­ній, рекламній документації та інформа­цій­них матеріалах додатково зазначати катего­рію м’якості – жорсткості подушок залежно від коефіцієнта поверхневої густини напов­нювача, з таким поділом: м’яка, середньої жорсткості та жорстка. Поділ подушок за цим критерієм доцільно проводити з метою розробки чинної нормативної документації на цей вид виробів, що полегшить вибір товару споживачем.
