Published: March 2023

In this paper, a general vector optimization problem with inequality constraints is considered, this topic is very popular and important model with a long research history in optimization. The generality of setting is mainly expressed in the following three factors. The underlying spaces being linear spaces without topology (except the decision space being additionally equipped with this structure in some results). The “orderings” in both objective and constraint spaces are defined by arbitrary nonempty sets (not necessarily convex cones). The problem data are nonsmooth mappings, i.e., they are not Fréchet differentiable. For this problem, the optimality conditions and Wolfe and Mond-Weir duality properties are investigated , which lie at the heart of optimization theory. These results are established for the three main and typical optimal solutions: (Pareto) minimal, weak minimal, and strong minimal solutions in both local and global considerations. The research define a type of Gateaux variation to play the role of a derivative. For optimality conditions, and introduce the concepts of on-set differentiable quasiconvexity for global solutions and sequential differentiable quasiconvexity for local ones. Furthermore, each of them is separated into type 1 for sufficient optimality conditions and type 2 for necessary ones. After obtaining optimality conditions, applying them to derive weak and strong duality relations for the above types of solutions following our duality schemes of the Wolfe and Mon-Weir types. Due to the complexity of the research subject: considerations of duality are different from that of optimality conditions, we have to design two more appropriate types of generalized quasiconvexity: scalar quasiconvexity for the weak solution and scalar strict convexity for the Pareto solution. So all the results are in terms of the aforementioned Gateaux variation and various types of generalized quasiconvexity. The results are remarkably different from the related known ones with some clear advantages in particular cases of applications.

Currently, the welding industry has made significant contributions in most production fields to meet the needs of people's lives. However, traditional welding methods have disadvantages such as: a large amount of energy consumption, production of many toxic gases that are harmful to the environment and the health of workers. Therefore, the friction stir welding method was introduced from the research of scientists to overcome the above disadvantages. Besides that, it is suitable for welding aluminum alloys and non-ferrous metals with low melting point. This green welding technology has been continuously researched to improve weld quality through two main research models: experiment models and numerical simulation models. Experimental results provide provides the basic mechanical properties of the materials at the weld and the process optimization parameters. It will be the basis to establish a numerical simulation model closest to reality, based on mathematical models and working principles, thereby helping to predict weld quality through prediction of formation defects, temperature distribution with changes in welding process parameters such as time, velocity, material or welding pin profile. In this study, the influence of threaded pin profiles on weld quality of alloy aluminum 7075 -T6 during friction stir welding was investigated by numerical simulation model through ABAQUS software to recommend a new pin profile bringing an efficient welding process. To increase the reliability of this research approach, the numerical simulation results of the temperature distribution are compared with the experimental results obtained from a foreign scientific paper with an average error of 14%. Threaded pin profiles are designed in combination with three cross-sections having different opening angles named TF0, TF30, TF60 and TF90. Coupled Eulerian-Lagrangian formulation is applied for this model where the welding tool is Lagrangian domain and workpiece is Eulerian domain. Because material deformation in friction stir welding process is large and related to temperature, the elastic-plastic Johnson-Cook model is used for workpiece. Results of this research shows a new pin profile named TF60 which it gives the best weld quality of the four configurations of the pin tool examined in this study through evaluating temperature distribution and predicting weld defect formation.

In the design of ship propulsion system, the study of oscillation is a great importance because they play a decisive role in the operating ability of the shaft system. Among ship shaft oscillations, axial oscillation has been only a particular interest after applying on ships for diesel engines with ratio of piston stroke and its diameter 3-4,4. In this paper, the special features of the computational model are presented when studying the axial oscillations on the ship shaft system. It should be emphasized that the system of differential equations in describing the free and forced oscillations can be obtained directly from the analogous equations of the torsion oscillation. However, unlike the torsional oscillation, the axial oscillation of the ship shaft system directly affects the hull through the thrust bearing. In order to solve with the problem of determining the forced and resonant axial oscillations based on the Runge-Kutta numerical method is done by directly integrating the system of 2nd order differential equations in describing the oscillations. Therefore, the paper presents the research results in proposing a procedure to reduce the order of 2nd order differential equations and providing an algorithm to solve the system of differential equations in describing axial oscillations. From that, it will be considered that the mechanism under which forces of variable value are applied to it, axial oscillation occurs. The accuracy in calculating of the axial oscillation depends not only on the accepted method of determining the free and forced oscillation, but also the proper in giving the parameters of the discrete model. If the masses are easy to calculate, the evaluation of the axial deformation of the crankshaft is not univariate because there are many formulas given on the basis of idealizing the crankshaft under the structure of bar. Hence, it is proposed to build a 3D model and determine the deformation of the engine crankshaft components by the finite element method.

The increasing trend of working time and pressure on students, especially passive posture due to using computers in the learning process with inadequate attention to health has made spinal abnormal symptoms more and more common in the world. In particular, spinal deformity is one of the reasons affecting the normal development of adolescents, causing many circulatory and respiratory diseases and leading to psychological effects as well. Early detection of spinal deformities is thus one of the important tasks in routine scoliosis screening at secondary school in many countries, but not yet in Vietnam. The purpose of this study was to test the use of the DIERS formetric 4D device to conduct a pilot study on the spinal deformity of a group of students to investigate the possibility of using this method for widespread deployment in the future of scoliosis screening program. This is a new spine measurement method that does not use ionizing radiation, gives multi-parameter results, and is suitable for periodic scoliosis screening for all ages. Experimental measurements were performed on a group of 40 students consisting of 26 males and 14 females. The results showed that most of the students had abnormal expressions such as hunchback, and scoliosis. 18 out of 40 samples showed pelvic dislocation. The above cases can be caused by prolonged sitting time, a lack of physical exercise, and a wrong sitting posture. Abnormal cases in women have some common features of living habits. The results of the mentioned pilot study allow us to determine the necessary factors to use the DIERS method in proposing the implementation of a mass screening program for spinal deformities, especially in the national school medicine program.

The process of formation and deposition of granular sedimentary formations containing oil and gas in sedimentary basins on the continental shelf of Vietnam is a key factor in the study to determine the distribution trend, characteristics and scale of the sedimentary formations in general and Miocene sediments in particular. Up to the present time, the majority of Vietnam's oil and gas exploitation basin are distributed on continental or coastal shelves, so the study of the origin and evolution of basins in general and components in particular (into reservoir system) still exists many gaps not only with geologists but also with petroleum research and exploration company on the continental shelf of Vietnam. The samples and data collected cover most of the onshore and offshore in Southeastern Vietnam, allowing the construction of the relationship boths the two areas that have traditionally been studied by the companys, with the lack of synchronous methods, closely links. The collection of research data, recently collected, created convenient conditions for linking and comparing the evolutionary history between the continental sediments and the continental shelf through the survey of collecting field samples and core samples at petroleum exploration drill wells come to clarify the origin, evolution, the trend of sedimentary materials transporting. The methodology conducted to research includes geotectonics, stratigraphic seismic analysis, borehole geophysical analysis, stress filed, core sample analysis, sedimentary lithological analysis, biostratigraphic analysis, analysis of U-Pb zircon isotope age and at last artificial intelligence. The study results can also be used to predict the presence and distribution of the Miocene sandstone petroleum formations in researching area.
Distribution of Present Heat Flow in the Phu Khanh Basin, Offshore Vietnam

This study aims to determine the distribution of present heat flow in the Phu Khanh basin from shallow water to deep water throughout the basin. The results from 42 present heat flow data points extracted from the global heat flow database by Goutorbe et al. (2011) indicated that there is an uneven distribution of the present heat flow in the research area. Heat flow accumulation in uplift structures in the north-west direction (78 - 86 mW/m2) of the Phu Khanh basin is usually higher than in trenches or deep depressions in the south-east direction of the basin (58 - 72 mW/m2). This is due to the sediment layer up to more than 10,000m thick in the deep water of the Phu Khanh basin. As a result, heat flow values in deep water are significantly lower than in shallow water of the Phu Khanh basin. The thick sediment layer acts as an insulator that prevents heat flow from escaping to the surface. The mean values of present heat flow calculated from wells TH - 1X and CMT - 1X are 85.60 mW/m2 and 83.20 mW/m2 respectively. These values are relatively consistent with the predicted results from Kriging 42 data points extracted from the global heat flow data set in the study of Goutorbe et al. (2011). The high present heat flow values can be explained by the fact that the Phu Khanh basin is still experiencing thermal subsidence because of its relatively young age (approximately 35 million years). This basin has not yet regained its thermal equilibrium value after the Early Oligocene - Miocene extension stage, so the present heat flow value is still high in this basin.

İktisat genel bir ifade ile bireylerin refahının nasıl artırılacağı sorunsalı üzerinde durmaktadır. Bu ise Neo-klasik iktisat düşüncesi açısından, tüketicilerin fayda maksimizasyonu, üreticilerin ise kâr maksimizasyonu amacıyla hareket etmeleriyle sağlanmaktadır. Üreticiler ile tüketicilerin bunu sağlamaya çalışırken rasyonel davrandıkları kabul edilmektedir. Bu açıdan kısaca serbest piyasa sisteminin hazları maksimum kılmakla, insanı mutlu kılabileceği varsayımı üzerinde durduğu ifade edilebilir. Ancak mutluluğun tek kaynağının bu haz duygusuna bağlı olmadığı, bunun yanında hayata ilişkin anlam ve mana boyutlarının da mutluluğu artırıcı etkileri olduğu düşünülmektedir. Easterlin Paradoksu ve Maslow ihtiyaçlar hiyerarşisinin üst katmanları buna ilişkin bir takım önemli ipuçları sağlamaktadır. Bu çalışmada, Covid-19 salgınının mutluluğun boyutları üzerindeki etkisi incelenmektedir. Mutluluğun boyutları olarak haz (hedonik), mana (eudeimonik) ve maneviyat (g-donik) boyutları ele alınmaktadır. Van ili örneğinden hareketle anket çalışması yapılmış, elde edilen veriler Regresyon, Korelasyon ve Anova testi ile değerlendirilmiştir. Bulgular maneviyatı yüksek bireylerin salgının ağır psikolojik etkilerinden çok fazla etkilenmediğini, geleceğe karşı daha az kaygılı olduklarını, lüks tüketim alışkanlıklarının fazla olmadığını, salgın sürecinde harcama eğilimlerini azalttıklarını göstermektedir. Hazcı bireylerin salgının yıkıcı etkilerinden en fazla etkilenen bireyler olduğu sonucuna ulaşılırken, mutluluğun anlam boyutundaki bireylerin salgının olumsuz etkilerinden, maneviyat boyutundaki bireylerden daha fazla etkilendiği ancak hazcı bireylerden nispeten daha az etkilendiği elde edilen bulgulardandır.

No Brasil, segundo a Política Nacional do Idoso (Lei 8.842, 1994) e o Estatuto do Idoso (Lei 10.741, 2003), considera-se idosa a pessoa com 60 anos ou mais de idade. Diante da tendência demográfica que aponta o aumento da população idosa e a necessidade de garantir acessibilidade em parques e áreas naturais para atividades de lazer voltadas a essa população, este estudo objetivou realizar um levantamento bibliográfico acerca do assunto nas bases de dados da Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) e do Portal de Periódicos da CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior), entre os anos de 2015 e 2022. Nessa busca, foram associados diferentes descritores. Neste artigo, são apresentados os resultados relativos à produção acadêmica sobre as condições de acessibilidade e inclusão da população idosa em parques e áreas naturais. Como será demonstrado pela análise dos resultados, é escassa a produção científico-acadêmica acerca desse tema.

У статті узагальнено досвід вдосконалення систем логістичного забезпечення підрозділів Національної гвардії України. Обґрунтовано засади удосконалення організаційної та функціональної структури логістичного забезпечення в контексті приєднання України до НАТО. Проведення військової операції залежить від того, наскільки повно і своєчасно війська будуть забезпечені всім необхідним, як скоро будуть повернені до підрозділів поранені, а також відновлені пошкоджені під час бою озброєння і військова техніка. Система логістики НГУ, створена в мирний час, також призначена для використання її в ході військової кампанії. Вона являє собою один з важливих чинників, що впливають на бойову операцію в цілому (поряд зі стратегією, тактикою і системою управління). Як відомо, 70–80% усіх професійних складських площ країни було у Київській області. З початком бойових дій компанії були змушені перевезти свої складські залишки та товари на захід України. Відбувся колосальний відтік до Львівської, Тернопільської, Івано-Франківської областей, Закарпаття. Усе це дуже сильно змінило і логістичні процеси, і ланцюги постачання, і вартість самих логістичних операцій. Якщо говорити про звичайні продовольчі товари, то все йде своєю чергою, все доставляється. Є затримки доставки товарів в окремі райони через високі ризики. Відмічається майже нульова авіаційна та воднотранспортна логістика. Велика частина вантажів перевозиться із залученням залізничного транспорту, але є певні складності пов’язані з відсутністю залізничних вагонів, пошкодженням електромереж на залізниці. Транспортування техніки і живої сили також має певні проблеми: немає достатньої кількості залізничних колій, бракує необхідного рухомого складу, не вистачає номенклатури необхідних вагонів. Крім того, багато мостів не призначені для пропуску великої ваги, наприклад, танка з трейлером, загальна бойова маса яких 50-60 тонн. Протягом перших днів бойових дій багато вантажів прямувало у війська в контейнерах. Часто-густо їх необхідно було перевантажувати, що приводило до збільшення часу, отже була задіяна велика кількість людських ресурсів і зусиль. До факторів впливу на логістику під час бойових дій можна віднести: вразливість логістичної системи, наближеної до прифронтових регіонів; неможливість доставки, коли йдеться про небезпеку; перебудова логістичних маршрутів, яка відбувається з певною періодичністю (деякі маршрути залишаються більш усталеними, а інші, навпаки, змінюються під впливом динамічної ситуації); відмова від тривалого зберігання вантажів на складах, орієнтування на роботу «з коліс», що допомагає звести до мінімуму надлишки; затримка в дорозі до доби, зумовлена об’єктивними причинами; нестача автотранспорту, аби у прифронтових регіонах в повній мірі покривати потреби логістичної галузі, та багато інших.

The results of monitoring and analysis of production and organisational indicators of more than 50 farms have been presented, identifying the main elements that characterise them. There have been covered the main principles of forming the system of technology parameters, the directions of minimizing the determining conditions that negatively affect the production process. It has been explained that enlargement of farms with 50-100 cows considerably raises the technological level of milk production and storage. There were determined the parameters of technological and technical solutions of the enterprises with the number of cows from 50 to 120 heads. There were determined limits of parameters limitation, produced energy efficiency was evaluated and modelled on the example of minimal size (50 cows with annual productivity from 7000 kg to 9000 kg of milk per head). The structure of energy intensity of production was calculated by types - milk, live weight of culled animals, gain of breeding animals received brood. The energy intensity of excrement and litter has been taken into account. It was calculated that the highest proportion in the structure of the energy content of products appropriate for feeding belongs to the energy content of milk produced - 85.7-88.6 %, and since it was the most influential factor in the coefficients of energy efficiency of the main and general products, the functional correlations of the energy content of products and fat were determined. The influence of changes in qualitative indicators of other types of products on energy consumption in production was calculated namely fatness of culled cattle and animals from which growth was obtained.
The functional determined correlations allow us to form the key elements of the cattle breeding production system interrelations, taking into account the peculiarities of a particular system of parameters, determine the energy efficiency of technological processes, and influence effectively the use of all kinds of resources.

Essential oil and leaf extracts of Melaleuca leucadendra L. demonstrated a series of biological activities of interest, including antioxidant, antimicrobial, antitumoral and anti-inflammatory properties. The aim of the current study was an in vitro evaluation of the antimicrobial activity of the cajeput essential oil against Gram-negative strains such as Escherichia coli (Migula) Castellani and Chalmers (ATCC® 25922™), Escherichia coli (Migula) Castellani and Chalmers (ATCC® 35218™), Pseudomonas aeruginosa (Schroeter) Migula (ATCC® 27853™) and Gram-positive strains such as Staphylococcus aureus subsp. aureus Rosenbach (ATCC® 29213™), Staphylococcus aureus subsp. aureus Rosenbach (ATCC® 25923™), methicillin-resistant (MRSA), mecA positive Staphylococcus aureus (NCTC® 12493), Enterococcus faecalis (Andrewes and Horder) Schleifer and Kilpper-Balz (ATCC® 51299™) (resistant to vancomycin; sensitive to teicoplanin) and Enterococcus faecalis (Andrewes and Horder) Schleifer and Kilpper-Balz (ATCC® 29212™) to assess the possible use of this oil in preventing infections caused by these pathogens. The cajeput essential oil was provided by Polish essential oil manufacturers (Bamer®, Włocławek, Poland). Antimicrobial susceptibility of the tested strains was performed by the Kirby-Bauer disc diffusion method. Our research has shown that cajeput essential oil exhibits antibacterial properties. Gram-positive bacteria were the most susceptible to commercial cajeput oil, which may indicate that the active biological substances in cajeput essential oil (including phenolic acids, tannins, etc.) may be potential agents against bacterial infections. Among Gram-negative bacteria, only Pseudomonas aeruginosa (Schroeter) Migula (ATCC® 27853™) strain was resistant to the cajeput essential oil. We did not observe statistically significant changes in the zone of growth inhibition after the application of cajeput essential oil compared to the control samples (96% ethanol). Our study may suggest that the use of cajeput essential oil may be helpful for a wide range of bacterial infections in veterinary, aquaculture, medicine, and beyond.

Relationship Between Biological Rhythm and Food Addiction in Obesity
Authors: Çeçen Serpil , Guleken Zozan
Published: March 2023

Objective: Obesity is a common, multifactorial, and epigenetic disease. Emotional eating and food addiction are common eating behaviors in obese people. Biological rhythm helps the body adapt to the light-dark cycle and relates to eating behavior, including obesity. Thus, the study aims to reveal whether food addiction, an important factor in obesity, is affected by biological rhythm.Methods: A total of 130 participants (obese=76, nonobese=54) participated in the study. All participant’s anthropometrics were recorded. Beck Depression and Anxiety Inventories (BDI and BAI) were obtained. Afterward, the Yale Food Addiction Scale (YFAS) form was filled out to evaluate food addiction. Finally, they were asked to fill in the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) form to assess biological rhythm.Results: Obese and nonobese subjects had a significant positive correlation with body mass index (BMI), fat mass, fat-free mass, body fat percentage, and YFAS between weight (p<0.001). BRIAN chronotype score and BMI were negatively correlated between obese subjects (p<0.05) but not in nonobese subjects. BDI and BAI were significantly positively correlated (p<0.05, p<0.001) with BRIAN subscales except for chronotype in obese patients. Thus, higher scores in BRIAN imply greater disturbances in biological rhythms. YFAS results were positively correlated with weight, BDI, BAI, and BRIAN subtype parameters in the obese group. In the nonobese group, there was a positive correlation between YFAS and BDI and no correlation between the YFAS and BRIAN subtype parameters.Conclusion: As a result, if the person is both obese and has been diagnosed with food addiction, obesity may have emerged as a continuation of depression, anxiety, and biological rhythm disruptions.

Published: March 2023

The field of neuroarchitecture explores how various architectural elements impact human physical and mental health, based on neuroscience principles. With the development of functional neuroimaging and electroencephalogram studies, researchers can now visualize and quantify how different architectural factors affect brain activity, emotions, and cognition. Mobile Brain/Body Imaging is a new research methodology that records a moving person’s brain activity and bodily sensations in real time, promising to be a useful tool for space and urban design. In this article, we discuss neuroarchitecture from the perspective of circadian rhythm, physical health, and mental health. Studies have shown that artificial light at night disrupts the circadian rhythm, leading to acute and chronic negative health effects. Conversely, creating a personcentered light environment or incorporating nature-like elements can have a positive impact on health. Research has also shown that exposure to nature reduces self-rumination and contributes to psychological well-being. Neuroarchitecture studies on other factors, such as ceiling height, wall colors, and the movement of people in the building, should be expanded to gain greater insights and practical applications. The convergence of neuroscience and architecture has the potential to identify architectural elements that benefit human physical and mental health.

Published: March 2023

Objective: This study investigated the specific symptoms of insomnia that are associated with depression and anxiety in patients with insomnia.Methods: This study was a retrospective analysis of the data collected from 219 patients diagnosed with insomnia. The Insomnia Severity Index (ISI), Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI) were used to assess the severity of symptoms of insomnia, depression, and anxiety. Spearman’s rank correlation and multiple linear regression analyses were used to analyze the data.Results: All seven items of the ISI had a significant relationship with symptoms of depression and anxiety. Difficulty staying asleep and problems with sleep interfering with daily functioning had the greatest associations with the BDI-II total score. Problems with sleep interfering with daily functioning also had the highest correlation coefficient with the total BAI score. Multiple linear regression analysis showed that difficulty maintaining sleep and concerns about how others perceive sleep problems were significantly associated with depression. Difficulty falling asleep and problems with sleep interfering with daily functioning were significantly associated with anxiety.Conclusion: This study suggests that specific symptoms of insomnia are associated with depression and anxiety in patients with insomnia. These findings may help clinicians to better understand the relationship between specific insomnia and affective symptoms and develop targeted treatment strategies for patients with insomnia.

Published: March 2023

This work is intended to develop a measuring tool for determining teacher perception of informal relationships. The pool of item created by researchers through a literature review has been presented with expert assessment of the validity of content, face and meaning, and a draft scale form has been created by making necessary revisions to the feedbacks. The draft form was applied to 214 teachers working in the central districts of Diyarbakır, exploratory factor analysis was made on the obtained data set and a six-dimensional scale structure consisting of 20 items was determined. In order to verify this structure, data were collected from 306 teachers working in the central districts of Diyarbakir, and the six-factor scale structure was confirmed based on the goodness of fit values estimated by confirmatory factor analysis. In addition, AVE (Average Variance Extracted), root of AVE, composite reliability and correlation among factors were checked, and it was seen that the scale provided the convergent and discriminant validity conditions as a result of the values reached. For reliability analysis, Cronbach's Alpha coefficients and composite reliability values were checked together, and it was seen that the scale had sufficient reliability values. The measurement invariance of the scale was tested according to the categories of gender (female-male), marital status (married-single), level of employment (primary school, secondary school and high school) and seniority (1-10 years, 11-20 years, 21 and above) and the formality of the scale, metric, scalar and strict invariance conditions were found to satisfy. Consequently, it was concluded that the scale in question is a valid and reliable scale, which can be used to measure teacher perception of informal relationships.

In Bangladesh, pickles and chutneys are very popular appetizers that give main dishes more taste. In this present study quality of selected commercial pickles and chutneys were evaluated by conducting physicochemical parameters and analyzing the adulterant. A total 19 samples were used for this experiment. The pickle and chutney samples were evaluated for physicochemical parameters including moisture content, acidity as citric acid, sodium benzoate, and arsenic in laboratory. The results suggested that, highest concentration of moisture content (49.80±0.21%), acidity (1.85±0.02 mg/Kg) and sodium benzoate (363.30±0.26 mg/Kg) were found in Tamarind chutney (C-1), Jujube chutney (B-3) and Mixed chutney (E-1) respectively. However, all of the samples estimated arsenic (As) levels remained within the corresponding guideline limit.  It is concluded that samples of moisture content (57.89%), acidity (68.42%) and sodium benzoate (15.79%) were higher than BSTI standard which is not suitable for food safety. However, pickles and chutneys are available in both good and bad quality in the market.
