Published: March 2023

In recent years the use of partition systems other than the widely used biphasic n-octanol/water has received increased attention to gain insight into the molecular features that dictate the lipophilicity of compounds. Thus, the difference between n-octanol/water and toluene/water partition coefficients has proven to be a valuable descriptor to study the propensity of molecules to form intramolecular hydrogen bonds and exhibit chameleon-like properties that modulate solubility and permeability. In this context, this study reports the experimental toluene/water partition coefficients (logPtol/w) for a series of 16 drugs that were selected as an external test set in the framework of the Statistical Assessment of the Modeling of Proteins and Ligands (SAMPL) blind challenge. This external set has been used by the computational community to calibrate their methods in the current edition (SAMPL9) of this contest. Furthermore, the study also investigates the performance of two computational strategies for the prediction of logPtol/w. The first relies on the development of two machine learning (ML) models, which are built up by combining the selection of 11 molecular descriptors in conjunction with either multiple linear regression (MLR) and random forest regression (RFR) models to target a dataset of 252 experimental logPtol/w values. The second consists of the parametrization of the IEF-PCM/MST continuum solvation model from B3LYP/6-31G(d) calculations to predict the solvation free energies of 163 compounds in toluene and benzene. The performance of the ML and IEF-PCM/MST models has been calibrated against external test sets, including the compounds that define the SAMPL9 logPtol/w challenge. The results are used to discuss the merits and weaknesses of the two computational approaches.

Abdominal pain
Authors: Parfenov Asfold I.
Published: March 2023

Abdominal pain is a symptom that determines the accuracy and timeliness of diagnosis, treatment, and prognosis. The article describes the causes of acute and chronic abdominal pain, particularly the pain in the abdominal wall, and the challenges in recognizing them. The pathogenetic features of visceral, parietal, referred, and psychogenic pain and the principles of symptomatic therapy are addressed. It is emphasized that complex invasive examinations of the abdominal organs are especially relevant for elderly patients who often have conditions that require computed tomography, including contrast-enhanced scans. Without losing the importance of modern examination methods used in clinical practice, the author states that a detailed medical history and a thorough physical examination can significantly narrow the work-up. Endoscopic and other instrumental invasive examinations should be strictly justified and applied with a cost-effective rational approach.

Aim. To evaluate the clinical and endoscopic features of diseases of the upper gastrointestinal tract (GIT) in patients with atherosclerosis of the mesenteric arteries (MA).
Materials and methods. The study included 48 patients with atherosclerosis of MA and 43 patients without atherosclerosis of MA, who were hospitalized in the department of vascular surgery of the Chelyabinsk Regional Clinical Hospital in the period from 2019 to 2021. All patients underwent multispiral computed tomoangiography of the visceral and lower limb arteries, esophagogastroduodenoscopy.
Results. Assessment of lesions of the upper gastrointestinal tract revealed a higher incidence of erosive and ulcerative gastroduodenopathies among patients with atherosclerosis of MA (60.4%), compared with patients without atherosclerosis MA (39.5%); p=0.047. Signs of severe atrophy according to the data of histological examination were statistically significantly more frequent among patients with atherosclerosis of MA (29.2 and 11.6%; p=0.031). According to the results of logistic regression, the following predictors of erosions and ulcers of the upper gastrointestinal tract were revealed: the severity of stenosis of the superior mesenteric artery (SMA) is more than 35%, the body mass index (BMI) is less than 25.9 and the total score on the HADS scale is more than 6.5 points for depression (p=0.008).
Conclusion. Erosive-ulcerative gastroduodenopathies and atrophy of the gastric mucosa are significantly more common in the group of patients with MA atherosclerosis. The main risk factors for erosions and ulcers of the upper gastrointestinal tract in patients with MA atherosclerosis are: the severity of SMA stenosis is more than 35%, a decrease in BMI is less than 25.9 and an increase in the HADS score is more than 6.5 points.

The main purpose of this study is to investigate the relationships between psychological resilience, perception of self-efficacy and hopelessness. In this context, it is aimed to examine the mediating role of self-efficacy between resilience and hopelessness. For this purpose, the data were collected online from 362 volunteer participants (217 female, 145 male) by using snowball sampling method. In accordance with the scope of the study, a questionnaire consisting of 'Demographic Information Form', 'Beck Hopelessness Scale', 'Short Psychological Resilience Scale' and 'General Self-Efficacy Scale' were applied to the participants. Firstly, the assumptions of normality and homogeneity were tested for the analyzes to be carried out on the obtained data. In order to test the statistical significance of the proposed mediation model, the Bootstrapping Method was used through the software developed by Hayes. Obtained results showed that psychological resilience was significantly and negatively related to hopelessness; but positively related to self-efficacy. In fact, self-efficacy perception was found to be negatively related to hopelessness. Lastly, according to the analyzes carried out within the framework of mediation models, it was found that self-efficacy had a mediation role in the relationship between psychological resilience and hopelessness. All findings were discussed within the framework of the related literature.
The Circular Economy, the SMEs, and the State: How to Govern a Circular Institutional Change Process?
Authors: KAPLAN Yılmaz , KULA Mehmet Emirhan
Published: March 2023

The linear economic (LE) system is increasingly becoming unsustainable as its take-make-use-dispose logic mercilessly exploits the environment. As an alternative to this, the circular economy (CE) has recently gained popularity. The CE promises a more sustainable system through decreasing resource leakage from the economic system via circulating economic activities from production to consumption. However, there is not a clear blueprint on the institutionalization of the CE. To provide an answer to this problem, this research focused on the Small and Medium Entrepreneurs (the SMEs). The research was designed as a qualitative case study benefiting from the secondary data derived from the literature and found that the structural dependence of the SMEs on the existing LE system prevents them from performing proper CE actions. As a solution, the state emerges as a macro-level rule-breaker, which can play a catalyst role in the SMEs’ transition to the CE. Particularly, it could provide necessary regulative frameworks, financial sources, technological infrastructures, and a circular change in consumers’ attitudes, which are strategically important to drive the SMEs towards the CE system. Therefore, this paper suggests that the re-conceptualization of state-market relationship is an initial need to successfully govern an institutional change towards the CE. Additionally, a successful CE centred transition also needs a differentiated institutionalization perspective due to the uniqueness of different cases.

Athletes are exposed to comments that include pressure, and psychological violence in the sports culture where gender-based power relations are intense.
A Textual Analysis of Turkish Advice Letters in the Construction of a Persuasive Agony Aunt
Authors: AKINCI OKTAY Suhan
Published: March 2023

As a representative form of popular culture, the continuation of advice letters written by the agony aunts in newspapers can demonstrate society's needs. Despite its commonality in everyday life, advice can be termed as a ‘complex and interesting speech act’ (Hyland and Hyland 2012) since sometimes it does not end in one sentence like other speech acts (e.g., requesting, apologies and thanking) (Trosborg 1995). Based on data from a collection of 100 advice letters written by the Turkish agony aunt gathered from the years 2020-2021, a textual meta discursivee analysis of advice letters is conducted to evaluate the types and frequencies of textual markers to find out how the agony aunt utilizes these textual elements to put forward her arguments. The findings reveal that 1) logical markers are extremely essential for persuading advice seekers and 2) adversatives and additives are necessary for providing a logical basis when advising advice seekers. The paper concludes by indicating that textual markers are essential for persuading advice seekers and potential readers when giving advice.
Missing Subjects of Social and Economic Development: Women with Headscarves
Authors: DAMA Nergis
Published: March 2023

In Türkiye, mandatory education is provided by the state, and therefore, individuals with fragile socioeconomic indicators do not experience barriers of inequality to inclusion to education. However, in about 1997, the women with headscarves also acquired visibility in education and this led to certain social events in Türkiye. The practice widely known as “headscarf ban” that began in 1997 decreed the expulsion of women with headscarves from the higher education process. When it is considered that the mandatory education in Türkiye is 12 years and that the undergraduate education takes 4 years, the headscarf ban during the 1997-2013 corresponds to a period in which a person accumulates her human capital. This study is on how women who have been systematically cast out from education and employment perceive: a) their forfeited role in the development of Türkiye’s economy; b) their own assessment of their lack of employment due to the headscarf ban; and c) being barred from education, their individual losses and Türkiye’s economic prosperity.
The Mediating Role of Organizational Identification in the Effect of Organizational Support Perceptions of Employees in Accommodation Businesses on their Prosocial Service Behaviors
Authors: TÜRK Okan , SUİÇER Musa , DOĞAN Yunus
Published: March 2023

Businesses in the accommodation industry are often those that engage in labor-intensive production, and as a result, employee and customer relations are of utmost importance. In order to improve the caliber of the services they offer, managers in the accommodation industry require their staff to display prosocial behaviors by developing strong cognitive and emotional relationships with their companies. The ability of employees to identify with organizations and show prosocial behaviors depends on the support provided within the organization and the degree of their perception of this support. Therefore, the study aims to determine the mediating role of organizational identification in the effect of organizational support perceptions of employees in accommodation businesses on their prosocial service behaviors. For this purpose, using the convenience sampling method in the research, data were obtained from 397 blue-collar employees in four and five-star accommodation enterprises operating in the province of Antalya by using the survey method. The obtained data were analyzed with SPSS 24.0 and SMART PLS programs. The findings of the study revealed that participants' perceptions of organizational support have a positive and significant impact on their prosocial service behavior and organizational identity. Additionally, it was determined that organizational identification influences prosocial service behaviors significantly and positively. The final finding was that organizational identification partially mediates the relationship between participants' perceptions of organizational support and prosocial service behaviors.

Authors: ÖZMEN Esra
Published: March 2023

The means of meeting people's needs are changing day by day. For example, the need for transportation has been provided by various vehicles until today and user satisfaction has always been taken into account. However, with the development of technology and the change in the way of meeting human needs, the level of acceptance and use of products by consumers has also changed. Scooters developed to provide ease of transportation can also be seen as a part of this change. Within the scope of the study, it was investigated at what level female participants used e-scooter technology to meet their transportation needs and at what level they accepted this technology. The factors affecting women's adoption of e-scooters are discussed in the context of the Technology Acceptance Model (TAM). The relationship between the perceived security factor within the scope of the study and the behavioral intention to use the e-scooter could not be measured. However, there are direct and indirect relationships between social impact, perceived ease of use, perceived usefulness and environmental sensitivity, and behavioral intention. As a result, inferences were made regarding the factors affecting the use of e-scooter by women.
Entre la lógica y los lenguajes. ¿Qué favorece más el aprendizaje de la programación?
Authors: Trejos Buriticá Omar Ivan , Muñoz Guerrero Luis Eduardo
Published: March 2023

El área que tiene más relación con la Ingeniería de Sistemas es la programación. Aprender a programar implica apropiar un conjunto de reglas lógicas y las posibilidades de unos lenguajes para implementar soluciones a determinados problemas en el computador. La búsqueda de caminos para que esta lógica de programación, que es diferente a la lógica deliberativa, sea asimilada es uno de los retos que tienen los ingenieros docentes que se desempeñan en esa área. El objetivo de este artículo es aportar una experiencia de investigación en el aula que permitió establecer un comparativo entre dos tendencias: la enseñanza de la lógica de programación o la enseñanza de los lenguajes de programación, como caminos diferentes para aprender a programar. La metodología utilizada implicó la designación de dos cursos paralelos con los cuales se desarrolló todo el curso, por los dos caminos planteados. Los resultados dejan entrever ventajas y desventajas que tienen cada uno de los dos caminos como preparación para los futuros ingenieros. Se concluye que en la medida en que se exploren caminos diferentes para la enseñanza de la programación, en esa misma medida se va a posibilitar el hallazgo de formas efectivas y eficientes de aprenderla.

Published: March 2023

In recent years, there has been an increase in online education. However, an adequate technique was not developed for online examinations. Some educational facilities have compiled assignments that students may copy and paste from the web, while others use remote proctoring, where a human proctor monitors what the students are doing online. Cheating in online tests remains common despite all the growth that has taken place in this field. This paper proposes an Artificial Intelligence (AI)-based system that can assist in the automatic detection of fraud in online tests. This method is both efficient and trustworthy. This system outperformed previous systems in experiments.

A Secure Symmetric Key Synchronization Using Session
Key Identifier Block Algorithm for LPWAN Networks
Authors: Hindumathi G. V. , D. Lalitha Bhaskari
Published: March 2023

Low-Power Wide Area Networks (LPWAN) have gained considerable importance with the usage and sustainable development of the Internet of Things (IoT). LPWANs have advantages; however, they have many limitations, including limited bandwidth, restricted payload size, and low power devices. Due to these limitations, LPWAN networks confront many challenges, like encrypting the data with the cypher chaining mode or implementing complex algorithms. Here, the cypher chaining mode cannot identify the next message if any packet has been lost because of the device's limited payload size and low memory. So, currently available algorithms cannot be used for LPWAN networks. Key is very important in cryptography; if an attacker compromises a secret key, it leads to a breach of the whole data. The best possible solution to prevent this breach is to frequently change the secret key. Here, we propose a novel algorithm to change the key for every message by synchronizing the sender's IoT device key. This system also proposes a Session Key Identifier Block (SKIB), implementing a session key for every message without any sequence number. The SKIB module identifies the session keys with the hash function and a shared secret key. The proposed work also compared the previous methods with experimental results.
Shale gas resources across the world: A future source of energy
Authors: Vamsi Krishna Kudapa
Published: March 2023

Unconventional natural gas resources are very important for ensuring energy security. It is a concern that conventional natural gas resources will be unable to meet growing supply requirements. This concern has prompted a scramble to secure long-term natural gas supplies. In a high oil and gas price environment, unconventional resources are viewed as important and economically attractive components of future natural gas supplies. Shale gas is natural gas produced from shale formations. Gas shales are organic-rich shale formations. Shale gas is a dry gas composed of methane. Various factors which have contributed to its rapid development are mainly advancements in horizontal drilling, hydraulic fracturing, and, perhaps most importantly, the rapid increase in natural gas prices in the last several years as a result of significant variation in supply and demand. India has a high potential for shale reserves. According to the available data, a comprehensive shale gas pilot project carried out in the Damodar Valley Basin has made an initial gasin- place estimate of 300 to 2,100 trillion cubic feet (TCF) in Indian shale gas basins, which is around 300 times higher than the Krishna Godavari Dhirubhai 6 (KG-D6) basin, by far the largest gas field in the country. In this paper, a brief review of shale gas reserves across the world and their government policies has been explained.

Published: March 2023

The menopausal transition is a challenging phase in a woman's life and has been compounded by the COVID-19 pandemic. This study aimed to examine the association between meaning in life, quality of life, and satisfaction with life among perimenopausal women during the pandemic, as well as to determine if there was a difference in attitudes towards life between working and non-working perimenopausal women. The study sample consisted of 114 perimenopausal women, with 64 being employed and 50 being non-employed. A quantitative cross-sectional design was employed, and the results showed that satisfaction with life was positively correlated with both meaning in life and quality of life. Working perimenopausal women had a higher level of satisfaction with life (mean score of 63.24) as compared to non-working perimenopausal women (mean score of 50.14), but there was no significant difference in quality of life or meaning in life between the two groups. The study highlights the impact of various social and personal factors on how women perceive their lives during the pandemic and underscores the need for increased support and resources for perimenopausal women in the workplace. Additionally, promoting menopause awareness in general and in the workplace could help to reduce social barriers and improve women's perspectives on life, leading to an improvement in their overall quality of life and satisfaction with life. This study insisted on the need for giving importance to this stage in women's life-rather passing it just like that. Policy makers in the HR field should make a note to the finding and incorporate necessary amendment in terms of the female workforce.

Authors: B. Chiranjeev Rao , Sushil Kumhar
Published: March 2023

A novel Opposition-based Whale Optimization Algorithm (OWOA) is utilized to build a power stabilizer and increase multimachine stability. A Conventional Power System Stabilizer (CPSS) with a lead-lag compensator is employed, and OWOA fine-tunes its settings using an objective function that minimizes the integral absolute error of speed deviations of generator rotors. Various time-domain simulations were performed to validate the superior performance of the proposed Power System Stabilizers (PSS). Furthermore, the performance of the proposed PSS is compared to a Whale Optimization Algorithm (WOA)-based PSS and a conventional PSS. The obtained results demonstrate the effective performance of the proposed OWOA-based PSS for power oscillation damping.

The primary goals of this paper is to contribute a useful method and present the advantages of Google Remote Procedure Calls (gRPC) for real-time two-way data transfer as well as to improve the security of microservices that use gRPC. The communication between two or more services is one of the key difficulties in splitting a monolithic application into microservices. When it utilizes gRPC to transmit in real-time, it responds quickly and with greater security. The gRPC protocol is now supported by application load balancing.
Blasting Optimization using O-Pitblast Software

Published: March 2023

The optimal cost of blasting is a major factor in the surface mining industry and must be addressed properly. The project will include the variability of components of blast design, such as change in azimuth of the holes intended for blasting to reduce explosive consumption and have a major role in controlling ground vibrations; pattern of holes (diameter of holes); electric and non-electric initiation; toe burden analysis; type of explosive used (slurry and ANFO); and adopting an efficient design by mathematical cost analysis using O-Pitblast software. The damage to temporary structures in surface mining that are located within close proximity of blasting faces is a serious problem and has to be countered using an alternating blast design in correspondence to the permissible Post-Production Verification (PPV) that a structure can withstand. The estimation of the PPV graph using seismographic data of the face must comply with different ground vibration equations to check whether the predicted model of blasting is up to safety norms and the demarking of the blasting zone.

Objective: To observe the clinical effect of different frequencies of transcutaneous electrical acupoint stimulation in treating postpartum pelvic girdle pain and promoting postpartum rehabilitation. Methods: From January to September 2022, 300 patients with pelvic girdle pain after spontaneous delivery in a hospital in Shaanxi Province were selected and randomly divided into three groups, low frequency, high frequency, and alternating frequency, with 100 cases in each group. In addition to routine postpartum care and psychological counseling, the three groups received transcutaneous electrical acupoint stimulation at low-frequency (2 Hz,) high-frequency (100 Hz), and alternating frequency (2/100 Hz), respectively. The differences in initial pain, pain scores before and after treatment, satisfaction with analgesic effect, and postpartum rehabilitation effect were evaluated among the three groups of patients. Results: There was a significant correlation between maternal age and postpartum pelvic girdle pain (P < 0.001), but no correlation was observed between newborn birth weight and postpartum pelvic girdle pain (P > 0.05). After 1d/2d of treatment, the pain scores and rehabilitation effect of patients in the alternating-frequency group and low-frequency group were significantly better than those in the high-frequency group, and the postpartum curative effect of patients in the alternating-frequency group was the best, followed by the low-frequency group, and the high-frequency group; the differences were statistically significant (P < 0.001). Among the three groups, the alternating-frequency group had the highest satisfaction with the analgesic effect and the highest rate of selecting the same analgesic regimen the next time; the differences were statistically significant (P < 0.001). Conclusion: Transcutaneous electrical acupoint stimulation at different frequencies is safe and effective in treating postpartum pelvic girdle pain and beneficial to postpartum rehabilitation. Sparse-dense wave stimulation is effective in treating postpartum pelvic girdle pain. It has the best effect in promoting postpartum rehabilitation and the highest patient satisfaction. Therefore, its application in clinical practice is highly recommended.

Objective: To analyze serum vitamin D levels in patients with clear cell renal cell carcinoma (ccRCC) by flow cytometry and to investigate the relationship between hypovitaminosis D status and hyperactivation of IL-6/STAT3 signaling in ccRCC. Methods: Eighty patients diagnosed with ccRCC by our oncology department from January 2019 to December 2021 were selected as study subjects, and the control subjects were selected from patients who were receiving health check-up from our hospital (matched according to case group:control group, 1:2), with 160 healthy patients. All serum samples collected from the case-control subjects were allowed to stand for 1–2 hours, centrifuged at 3000 rpm for 10 minutes, and stored in a -80°C refrigerator, from which they were removed and thawed to measure 25-hydroxyvitamin D (25(OH)D) and interleukin 6 (IL-6) levels. Results: The blood calcium level of patients in the cancer group was significantly lower than that of patients in the non-cancer group, and the difference was statistically significant (P < 0.05). The IL-6 level of the cancer group was significantly higher than that of the non-cancer group. In high vitamin D state, the IL-6 level of the non-cancer group was higher than that of the cancer group, and the average concentration of IL-6 in both the cancer group and the non-cancer group was significantly higher in low vitamin D state compared with high vitamin D state (P < 0.05); the correlation between hypovitaminosis D status and renal Ki-67 was found to be positive. Conclusion: The results showed that serum IL-6 levels were elevated in the cancer group and circulating serum 25(OH)D levels were negatively correlated with IL-6 levels. In addition, signal transducer and activator of transcription 3 (STAT3) signaling in RCC tissues was activated in ccRCC patients and in those with low vitamin D status among the cancer group and was higher than that in those with high vitamin D status. These results suggest that hypovitaminosis D status in ccRCC patients is associated with activated IL-6/STAT3 signaling and the activation of tumor proliferation markers proliferating cell nuclear antigen (PCNA), cyclin D1, and Ki-67.
