Authors: BOZKURT UZAN Şeyma , ATALAY Kutluk
Published: July 2023

In recent years, machine learning applications are being used in almost all areas of lives. The main benefits of using machine learning in marketing can be exemplified as follows; content creation, marketing budget optimization and recommendation systems. Recommendation systems are very important and useful when it comes to retaining the current customer. With the help of recommendation systems, companies can retain their customers by recommending their own products, services and contents. In this study, text mining, forecasting processes were carried out using the Netflix contents dataset shared by the data science platform called Kaggle. TfidVectorizer function was used to deal with text data while creating recommendation systems. Two different recommendation systems functions were created in this study.   While first recommendation system function performs only based on title feature of the Netflix contents dataset, the second recommendation system function performs with title, director, cast, listed_in and description features. Thanks to the results of the analysis, it is possible to evaluate the new productions on Netflix on the basis of the features of Netflix contents dataset included in the study. The proposed recommendation system functions provide greater prediction accuracy than conventional systems in data mining. Espicially the recommendation system function that has been developed secondly with the name “get_recommendation_new” uses all features in Netflix contents dataset to recommend new contents to the users.

Robust Image Watermarking in the Wavelet Domain
Authors: Younis Dr. Hameed A.
Published: July 2023

The growth of new imaging technologies has created a need for techniques that can be used for copyright protection of digital images. In this paper, a new and robust spread spectrum basedwatermarking scheme has been proposed.The proposed scheme depend on both Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT). First, we decompose the image by DWT into asingle level. Then, the approximation part is divided into blocks. The embedding is done in an adaptive fashion depending on the mean (M) of the block. A chaotic sequence of real numbers, depends on asecret key, is embedded as a watermark in the DCT coefficients of the selected blocks. Detection stage generates a watermark which would be compared with the original watermark, by the correlation measure, to determine the existing of the watermark or not. Different tests have been experimented to explain the transparency and the robust of the proposed scheme.

Authors: Vovk Liudmyla , Nedavnii Dmytro
Published: July 2023

The purpose of the research is to analyze existing game engines and study the possibilities of developing and implementing a game engine based on physical processes using a new approach that will expand the capabilities of game environment modelling.
The research methods are based on the implementation of general scientific and specific methods, including analysis, synthesis, comparison, analogy and modelling, system-structural analysis, methods of theoretical systematization and generalization of results, and scientific modelling, which allowed for a meaningful analysis of the subject matter.
Scientific novelty. A new approach to the creation of a game engine based on physical processes, which uses algorithms for calculating collisions and dynamic modelling of solids and liquids, is proposed.
Conclusions. The currently functioning game engines are analyzed and the characteristics and features of physical engines are described. It is emphasized that the physics engine in game development performs two main functions: detecting collisions between objects and simulating forces and movements resulting from these collisions. In addition to simulating the physical processes of solids, physics engines can implement additional features: special support for modelling the movement of solids, water and other liquids, simulation of fabrics and clothing, various particles, additional support for character simulation – high-level character controllers, built-in support for rag-dolls, and support for animation. A new approach to creating and using a game engine based on physical processes is described, which allows creating more realistic game environments using a variety of effects, simulating the physical processes in the game. The game engine, created on the basis of a new approach to solving the problem, uses algorithms for calculating collisions and dynamic modelling of solids and liquids, which expands the capabilities of activity modelling, ensuring high accuracy and realistic visualization of processes. The new approach allows expanding the capabilities of the game engine and supporting a variety of game scenarios.

Published: July 2023

The purpose of the article is to study, analyze the possibilities and substantiate the creation of a web-oriented system of a catering establishment (pizzeria) based on the ontological approach, as well as to develop the corresponding software. Achieving the aim of the study involves the following tasks: forming a multi-level ontological model of the subject area (catering establishment – pizzeria) and developing an appropriate web-oriented system on its basis.
The research methods are the main methodological approaches and technological tools for web-based systems development based on the use of an appropriate multi-level ontological model. Such methods include, in particular, systemic and comparative analyses (to identify the features of web-oriented systems of catering establishments) and the expert evaluation method (in determining the objects of the subject area and the relations between them).
The scientific novelty is the study and analysis of modern technologies for the development of web-oriented systems and multi-level ontological modelling of various subject areas, including catering establishments (e.g., pizzerias), the results of which can be used in the development of their software product – a web-oriented system of a catering establishment.
Conclusions. The paper investigates the known views on the modern approach to the development of web-oriented systems based on the implementation of the ontological approach. The proposed ontological model of a catering establishment (pizzeria) is described as a formal specification of knowledge about the selected subject area, its objects and the relationship between them (for a clear and complete representation of the subject area), which plays a significant role at different stages of creating and modifying a web-oriented system. The proposed ontological approach, which involves the development of an appropriate multi-level ontological model, has been used in the design of a web-based system for a restaurant (pizzeria).
The use of an ontological model in the development of a web-based system of a catering establishment (pizzeria) helps to reduce the risk of errors in the structure of the system, the component and elemental composition of the system and its information base; more accurate perception of the subject area (catering establishments specializing in different cuisines of the peoples of the world (for example, Ukrainian, Japanese, American, but preferring Italian); use in the model representation of the subject area not only formalized means (formal grammar, descriptive logic, etc.) but also natural languages; making more precise queries to the system’s information base (database and the corresponding knowledge base).

Published: July 2023

Historical material in teaching and learning activities in schools is often considered the most boring because it contains past facts. This is sometimes not realized by the subject teacher. The boring thing lies in the role of the teacher who prepares and teaches it. Because the output of teaching and learning activities experienced by students is an essential understanding, and positive values; nationalism, and patriotism can be practiced in social life. The purpose of this research is to provide understanding to teachers as well as students that the use of the role playing method is considered important to change the mindset that history lessons are boring. Because in its application it requires cooperation and inspiration for the role played. So it is hoped that the values and attitudes of patriotism and nationalism will become stronger in the souls of students and the younger generation of Indonesia in general. The results of this study have provided an understanding of the learning actors; The teacher said that the role playing learning method is an appropriate alternative method in teaching history subjects. Thus, history subjects which are loaded with events or incidents, places, and times will be more meaningful if the flashbacks in the learning activities are carried out through role playing; imitating the characters in the story, recreating the atmosphere and place of events or events.

Published: July 2023

Data is today's most powerful tool; valuable facts and information can be determined by analyzing them using appropriate techniques and algorithms. Also, the rapid increase in access to Internet technology to a large mass of people worldwide has increased the importance of analyzing data generated on the web much more than before. The preceding discussion of this research is sales forecasting in marketing, which is very important in this topic. Marketing is a tool through which people's standard of living is developed, which is done before and after the sale. This research presents a model based on a dynamic analysis system for forecasting marketing sales based on the AGA-LSTM neural network model. It is challenging to recognize emotions in natural language, even for humans, and automatic recognition makes it more complicated. This research presents a hybrid deep-learning model for accurate sentiment prediction in real-time multimodal data. In the proposed method, the work process is such that after extracting emotional data from social networks, they are pre-processed and prepared for pattern discovery. The data is evaluated in the adaptive genetic algorithm, and the pattern is discovered in the designed neural network, and this pattern is discovered after discovery. The cornerstone of sales policies is improved. The adaptive genetic algorithm was used to optimize the parameters of the LSTM model, and the model can predict the types of goods and the total volume of online retail sales. In the simulation of the proposed method, in 3000 rounds of training, an accuracy of 76 has been achieved, which is an improvement of 11% compared to the primary method.

Authors: Krasteva Elena Sergeeva , Anastasova Vanya Nikolaeva , Zunzov Elean Ivanov , Kiskinov Petar
Published: July 2023

Background Treatment of patients with post-traumatic severe and chronic wounds poses many challenges. A large number of dermal analogs have been invented in an effort to overcome these challenges. Matriderm, a biosynthetic dermal analog, is made from bovine collagen and elastin. The aim of our study was to prove the effectiveness of MatriDerm® combined with skin grafting versus skin grafting alone in these difficult-to-heal wounds.

Material and Methods:  Twenty-two patients with post-traumatic defects with bone exposure and chronic wounds treated in the Clinic of Plastic Reconstructive and Aesthetic Surgery of the University Hospital “St. George” were included in this prospective study. The mean age of the patients was 58 years. The patients were divided into two groups: the experimental and the control group. The patients in the experimental group received a Matriderm appliance and a split-thickness skin graft, while those in the control group received only a split-thickness skin graft. All patients gave their informed consent to participate in the study.

Results: The hospitalization period in the experimental group was 3 weeks and 5 days and in the control group 8 weeks. The period of complete healing was shorter in the experimental group patients (5 weeks) compared with control group patients (9 weeks) with a difference reaching statistical significance (P<0.05). Matriderm enables effective healing and improves elasticity in the treatment of patients with post-traumatic severe and chronic wounds.

Conclusions: With our study, we conﬁrm the evidence of the clinical use of MatriDerm® technology in the healing of soft tissue wounds and prove the effectiveness of combining MatriDerm® and skin grafting for the ﬁrst time. Moreover, we observed a reduction in wound contraction and an improvement in elasticity, quality of scar tissue, and dermal architecture.

Objectives: The purpose of the work is to analyze the impact of health care, key factors and problems that affect the final outcome of treatment in patients with a stoma, as well as suggestions and guidelines for improvement.

Material and Methods: The results of 10 studies were reviewed including clinical trials, randomized prospective and retrospective studies published between 2011 and 2021.

Results: Education of patients, their families, and medical staff is crucial in improving the quality of life of patients with stoma but also in reducing potential complications of stoma, along with stoma marking. It is also necessary to pay special attention to psychosocial problems in patients, as well as stoma problems in Bosnia and Herzegovina.

Conclusion: More needs to be invested in educating staff, patients and their families about stoma, and integrating stoma patients into society in order to improve their life quality.
Pulmonary Rehabilitation for Chronic Lung Diseases.
Authors: Neçaj Ledi
Published: July 2023

Chronic Obstructive Pulmonary Disease (COPD) is now the main cause of disability in the developed world. The advance of COPD is related to increasing breathlessness, disability, and periodic hospitalizations.  An aging population in the developed world and increasing cigarette consumption in developing countries expand the global impact of this condition. The disorder associated with COPD leads to a decrease in physical activity and failure of functional independence.

The aim of this study was to evaluate the effects of PR in patients with normal exercise capacity on health-related quality of life and exercise capacity.

The mean FEV1/FVC was 59.4± 14.1%, and the mean FEV1 was 64.8± 23.0% as expected. Most topics had mild to moderate COPD. The PImax and PEmax were normal. These subjects had no previous participation in home-based or hospital-based PR. All the subjects had normal maximal V˙O2 and work rate before PR.

After PR there were still considerable improvements in maximal V˙O2 (mean increase of 101.3 mL/min, p <0.001) and work rate (mean increase of 8.2 watts, p<0.001). Ventilation, heart rate, and mean blood pressure were constant following PR. The maximum oxygen pulse at maximum exercise was significantly increased with PR (p<0.02). The SpO2 and end-tidal PCO2 at peak exercise did not significantly improve after PR.

 Although dyspnea scores at rest were low and did not improve significantly with PR, dyspnea at end-exercise was significantly improved after PR (p=0.01). PR should be the responsibility of the clinical management of patients with COPD, even for those with normal exercise capacity. However, the benefits of disease progression, hospitalization, and survival for these patients remain unknown.

The main role in the management of any chronic disease, including lung disease, is to improve the quality of life (QL) in patients.

Conclusion; Although strongly recommended by scientific societies pulmonary rehabilitation programs still need to be more widely implemented. PR programs have shown a high level of evidence of benefits in chronic respiratory patients, particularly those with COPD.

Authors: Álvarez-Aterhortúa María Teresa , Mestre-Mogollón Gilma
Published: July 2023

La etnoeducación ha sido un proceso que ha tenido avances jurídicos, pero no se han reflejado en la praxis; en el contexto colombiano, no han habido efectos o transformaciones significativas en las comunidades a partir de este enfoque. Atendiendo a esta problemática, es perentoria la realización de investigaciones históricas críticas que develen las causas para pensar en soluciones pedagógicas y políticas; por tanto, como objetivo se plantea analizar el desarrollo histórico de la etnoeducación en el departamento de Bolívar. Para ello se empleó una metodología de enfoque cualitativo con técnicas etnográficas como la entrevista semiestructurada y se acudió al uso de fuentes documentales como la prensa. Los resultados encontrados apuntan a afirmar que hay un desconocimiento de las realidades culturales de las comunidades y de los fundamentos de la etnoeducación, por lo cual, se requiere formación de maestros, transversalización curricular y la generalización para toda la población.
La cobertura mediática de PISA en la prensa de República Dominicana
Authors: González-Mayorga Héctor
Published: July 2023

A pesar de los esfuerzos del Ministerio de Educación de República Dominicana por mejorar su sistema educativo, el país ha obtenido malos resultados en su participación en PISA 2015 y 2018. Sin duda, los medios de comunicación han contribuido a la difusión de dichos resultados en la sociedad. En el presente estudio se describe cómo ha sido la presencia de PISA en los artículos publicados en tres periódicos dominicanos entre 2015 y 2022. Los resultados demuestran un creciente interés por PISA en la prensa. La mayor parte de los artículos son noticias que utilizan PISA como argumento para referirse al desempeño del alumnado y a la calidad del sistema educativo. No obstante, predomina un tono negativo en la mayoría de los artículos. Se concluye que la prensa dominicana ha contribuido a avivar el debate sobre la calidad educativa, con lo cual cumple uno de los grandes objetivos de la OCDE.

Este estudio busca identificar las medidas educativas y disciplinarias según la gravedad de las faltas para fomentar una convivencia escolar armoniosa y comparar las medidas educativas en función de la regional educativa, el rol (alumno o profesor), el sector, el nivel y el sexo. La metodología es cuantitativa, con un alcance exploratorio, descriptivo y un diseño no experimental. Se utiliza un muestreo por conglomerados de forma aleatoria, dividido en las 18 regionales educativas del país, con 10,114 sujetos entre alumnado y docentes. Los resultados revelan que un 96.8 % de la muestra conoce las normas de convivencia educativa, y un 89.1 % indica que se aplican en los centros. La mayoría de las medidas disciplinarias utilizadas en el alumnado corresponde a las faltas leves, y el diálogo reflexivo es la más utilizada. También se evidencia que las medidas pueden ayudar en la mejora de la convivencia escolar, ya que su presencia establece un esquema de consecuencias para el alumnado, y esto disminuye los conflictos en el contexto educativo.
Function of cascade compressors and power consumption optimization in ammonia liquefaction process: a system evaluation with a 6 sigma approach
Authors: GEZERMAN Ahmet Ozan , YETGİN Ali
Published: July 2023

Ammonia is stored as a liquefied raw material as it is used in the fertilizer and cooling industries. The use of multistage compressors during storage is essential, as the boiling point is very low (-33°C) due to a typical petroleum derivative. Because pressure-temperature optimization with a typical single-stage compressor does not allow ammonia to be stored under atmospheric conditions. The use of condenser and throttling valves used in cooling systems together with multi-stage compressors for storage in atmospheric conditions allows ammonia to be stored in liquid form during storage.

In this study, a method has been developed to optimize the energy consumption by calculating the power consumption for the pressure and temperature conditions determined for the liquefaction of anhydrous ammonia, to improve the liquefaction conditions and to minimize the energy consumption.

Background & Aims Interpersonal cognitive distortion (ICD) is one of the psychological problems in old age that causes a person not to have a correct and logical understanding of relations. Its continuation can lead to anxiety and depression. This study aims to determine the ICDs among the community-dwelling elderly in Tehran, Iran. Materials & Methods In this descriptive-correlational study, participants were 200 older people dwelling in the urban parks in Tehran, Iran who were selected using a cluster sampling method from December 2020 to October 2021. Data collection tools included a demographic form, abbreviated mental test score (AMTS), and interpersonal cognitive distortion scale (ICDS). The collected data were analyzed in SPSS software, version 16 software using descriptive statistics (Mean±SD, No. (%)) and inferential statistics (Pearson correlation test, independent t-test, analysis of variance). Results The mean total score of ICD was 52.53±8.29 out of 95, which indicates the moderate level of ICD among the elderly. In terms of the dimensions of ICDS, the unrealistic relationship expectations had the highest mean score (2.91±0.57), while the dimension of interpersonal rejection had the lowest score (2.64±0.52). There was a significant relationship between the age of the elderly and their ICD (P=0.03). Conclusion Considering the existence of a significant relationship between ageing and cognitive distortions, The nurses working in healthcare centers in Mashhad should take it into account in interventions for the elderly.

In the welcoming program, the nurse first introduced herself to the patients and their families, and if needed, made them familiar with the hospital and its goals and environment, how to reach psychiatrists, and regulations during hospitalization. This program continued by acquainting patients with their rights, the hospital's rules, treatment team, welfare amenities, inpatient wards, electroconvulsive therapy unit, clinics, support center, and by handling complaints and criticisms. For internal evaluation, a survey form with 5 open-ended questions was designed without including demographic characteristics and distributed among the hospital departments. The responses were collected and analyzed using the content analysis method. Results The results of internal evaluation showed that 92% of the patients and their families were satisfied with the welcoming program and perceived it as very good and excellent. Half of the patients and their families (50%) believed that some nurses were caring and some were careless and did not take care of problems well. They perceived that psychiatrists and psychologists did not spend much time with the patient, and their visits were done very late. Conclusion Based on the perceptions of the patients and their families about the welcoming program, it seems that they are satisfied with the program in overall. The result can motivate other psychiatric and non-psychiatric centers in Iran for the implementation of a welcoming program.

Background & Aims Breast cancer is one of the common diseases in women that endangers their physical and mental health. Rumination is one of the psychological problems in these women. The present study aims to determine the effect of an educational program based on hope therapy on the rumination of women with breast cancer. Materials & Methods This is a quasi-experimental study. The study population consist of all women with breast cancer referred to the chemotherapy departments of hospitals affiliated to Zahedan University of Medical Sciences. The sampling was done using a continuous method. Then, the samples were divided into intervention (n=50) and control (n=50) groups randomly by lottery method. The intervention was conducted at eight group sessions, twice a week. The data collection tools were a demographic form and the Ruminative Response Scale (RRS). The data were analyzed in SPSS software, verion 16. Results The mean score of rumination before the intervention was not significantly different between the two groups (P=0.29). After the intervention, the difference between the two groups was significant (P=0.0001). The paired t-test results showed a significant difference in the mean score of rumination before and after the intervention in the intervention group (P=0.003), but there was no significant difference in the control group (P=0.89). Conclusion Education based on hope therapy can positively affect the rumination of women with breast cancer. By an hope therapy-based intervention, the disturbing thoughts, which are mostly related to disease and despair, can be reduced in women with breast cancer experiencing rumination.

Idiopathic cardiomyopathy in hamsters can cause death due to cardiac failure. The current case study investigated the capability of imaging to reveal possible cardiomyopathy in a dead hamster. To this end, the cadaver of a 6-month-old male Roborovski dwarf hamster, which showed acute respiratory symptoms a few days before its death, was examined by virtopsy to discover the cause of death. Postmortem radiography was not efficient enough to evaluate the heart due to postmortem lung atelectasis that increases lung opacity and diminishes the contrast between lung and heart. Postmortem computed tomography can be helpful for the assessment of cardiac size. Consistent with postmortem echocardiographic studies, an increased thickness of the left ventricular parietal wall and the interventricular septum and dilation of the left atrium were observed. Thus, hypertrophic cardiomyopathy was determined by imaging and confirmed by the conventional necropsy approach. It showed that the cause of death was acute cardiac failure following idiopathic hypertrophic cardiomyopathy.

Background: Parturition depression is an important physiological problem, and several attempts have been made to ascertain this physiological phenomenon. Natural monoterpenes like α-pinene have numerous beneficial properties, but no studies have been done on their antidepressant potential in postpartum animals. Objectives: This study aimed to determine the effects of prenatal administration of α-pinene on the antidepressant-like behavior of mice following delivery. Methods: Pregnant female mice were randomly assigned into four groups. In the control group, the animals were injected with saline on their 5, 8, 11, 14, and 17 gestation days (GD). In groups 2 to 4, pregnant female mice were injected with α-pinene (0.1, 0.5, and 1 mg/kg, respectively) at GD 5, 8, 11, 14, and 17. On day 2 postpartum, open field test (OFT), rotarod, forced swimming test (FST), and tail suspension test (TST) were used to evaluate the antidepressant activity of α-pinene in mice. Also, serum samples were taken to determine the antioxidant activity. Results: According to the results, α-pinene (0.5 and 1 mg/kg) significantly increased activity in OFT and staying on the rotarod (P≤0.05). Also, α-pinene (0.5 and 1 mg/kg) diminished immobility time (s) in TST and FST on postpartum mice (P≤0.05). α-pinene (0.5 and 1 mg/kg) decreased malondialdehyde while increased glutathione peroxidase, superoxide dismutase, and total antioxidant status levels in postpartum mice as compared with the control group (P≤0.05). Conclusion: It seems that prenatal administration of the α-pinene can alleviate postpartum depression via its antioxidant property in mice.

Background: Adiponectin, leptin, and ghrelin are metabolism regulatory factors affecting milk production and reproductive performance. Objectives: This study aimed to investigate the adiponectin, leptin, and ghrelin serum concentration in predicting Holstein cows’ reproductive and milk production indexes in the post-partum period. Methods: In this research, 45 clinically healthy and pregnant Holstein dairy cows were randomly selected near the forthcoming calving. Blood samples were taken from the jugular veins of cows 15 days before and after parturition, and serum concentrations of adiponectin, leptin, ghrelin, and some other metabolic biochemical parameters were measured. The animals were monitored for milk production and reproductive parameters for 3 consecutive months. Results: Findings showed no significant difference in adiponectin concentration between the pregnant and non-pregnant cows following the first artificial insemination (AI); however, pre- and post-partum serum concentrations of leptin, ghrelin, and insulin were higher in conceived cows following the first AI (P<0.05). A significant negative correlation was found between post-partum serum adiponectin concentration, the number of services before conception, and mean milk production levels (P<0.05). However, adiponectin did not have a long-lasting effect on the reproductive and milk production indexes because of other studied variables. Conclusion: It was concluded that the post-partum increased serum adiponectin and ghrelin and decreased leptin concentrations could not predict the reproductive and milk production indexes.
