Published: December 2023

This research focuses on the Ibu Sibuk community, an online community that empowers mothers to become influencers and resellers through social commerce platforms. The background of this research includes the community's goals, the platform's success in attracting members and brands, and the members' experiences in using communication technology to interact in the community. This study used a qualitative approach with a case study design to understand the role of the IbuSibuk community for women who already have a family and are mothers. The research informants consisted of two members and two administrators of IbuSibuk, who were selected through a purposive sampling technique. Data were collected through face-to-face or online interviews, literature reviews from academic journals, and website information. The research results show that IbuSibuk is an online community that helps working mothers earn extra income as influencers by connecting them with various brands. This community empowers mothers economically through the programs and activities offered but also faces technological barriers such as network and digital literacy issues and the potential for fraud. Nevertheless, technology within IbuSibuk extends its reach and facilitates offline activities such as product launches. Overall, IbuSibuk serves as a bridge between brands and influencers, empowers mothers economically, and creates a supportive and motivating environment for its members.

Published: December 2023

This paper analyses research developments in the dynamics of stakeholders and their impact mechanisms on the creation of value through a literature review. Three databases, Scopus, Science Direct and Google Scholar are selected to search articles. This study employs a quantitative descriptive analysis and a qualitative thematic analysis to provide a perspective of the data. The findings of the review reveal that stakeholder dynamics management is embedded in project environments and that the dynamic nature of the stakeholder salience attributes can be classified under stakeholder influence and engagement, project lifecycle and dynamics, value creation and framing, and project and stakeholder-associated risk. However, from the characterisation and the drivers of stakeholder dynamics discussed in the literature, the perspective of project risk dynamics has been understudied, with a focus mainly on stakeholder-associated risk to the project, and less on project risk and the stakeholder interactions related to potential losses or gains by stakeholders from such project decisions and activities. Although there is a recognition of the importance of managing stakeholder dynamics within project environments, the factors that affect stakeholder dynamics and their impact on the creation of value for industrial maintenance projects are still unclear. The outcome of the literature review can assist in providing the foundation for the authors’ empirical work of developing a novel conceptual framework for analysing stakeholder dynamics and their impact on maximising value creation in the context of industrial maintenance projects.

Published: December 2023

Marine bivalves are rich in polyunsaturated fatty acids. Cerastoderma glaucum is a potentially commercial sea cockle that inhabits the Mediterranean and the Black Seas. This bivalve mollusk contains omega-3, omega-6, and omega-9 fatty acids. However, its lipid composition remains understudied. When determining total lipids, their classes, and fatty acid composition, standard methods often have to be adapted to the object in hand and tools available. The research objective was to develop a complex lipid analysis method for aquatic organisms. The study featured total soft tissues of C. glaucum harvested from the pseudolittoral zone on the sand and silt soil of the Sevastopol coast of the Black Sea. The chromatographic methods made it possible to identify total lipids and classify them into phospholipids, monoglycerides, diglycerides, sterols, and triacylglycerols. The subsequent densimetric determination involved a flatbed scanner and the TLC Manager 4.0.2.3D software. The fatty acid composition for total lipids was studied using the chromatography-mass spectrometric method. The existing methods in lipidology were adapted for determining total lipids, their classes, and the fatty acid composition of total lipids in C. glaucum. The article introduces a detailed description of the method for determining total lipids, as well as of how to prepare equipment and reagents to classify common lipids using multidimensional thin layer chromatography. It also contains an authentic scheme of chromatographic baths for stepwise separation, densitometric measurements, and examples of fatty acid chromatograms and mass spectra. The new sample preparation method for determining fatty acids in total lipids by gas chromatography demonstrated a minimal loss in native structure and proved to be less aggressive than standard methods of sample derivatization. The new method for lipid analysis of clam tissues appeared to be economical, less time-consuming, and reagent-intensive. It can be recommended for small laboratories engaged in bioenergetics or comparative analyzes of aquatic organisms.

The article discusses the dairy industry in the Chuvash Republic, Russia. The Russian Federation is experiencing a shortage of milk. Currently, the per capita milk consumption in the country is by more than a quarter behind the rational intake recommended by the Ministry of Health, which is 325 kg. However, the Chuvash Republic boasts 373 kg of per capita milk production, which is by 71% higher than the average data for the rest of the country, and the high quality of Chuvash milk is unanimously confirmed by leading domestic experts. The authors analyzed the success factors of milk production in the Chuvash Republic to be extrapolated on the entire domestic industry.

The research relied on such demographic data as the ratio of urban vs. rural population; dairy herd data, e.g., livestock population, farm types, dairy productivity, etc.; dairy production and processing business data. The methods included systematization, generalization, grouping, statistical data processing, and analysis of temporal dynamics indicators.

The Chuvash Republic has a large percentage of rural population and a lot of subsidiary dairy farms: 22 000 farms own more than 60% of dairy cows in the region and provide 55% of milk processing volumes. Subsidies allocated by the local government allow farm owners to ensure the high dairy productivity of cows. Most of the milk in the Chuvash Republic can be classified as near-organic. Leading regional milk producers have their own agricultural lands to provide environmentally friendly feed, as well as specialized premises for herd keeping and milking, retail outlets to sell their products, etc. A third of enterprises maintain the milk productivity at 7800–9200 kg, which is as high as in Denmark, the Netherlands, Great Britain, and Germany. Most Chuvash dairy farmers owe their high results to the state support funds allocated for the purchase of breeding cattle. The twelve largest milk producers in the region provide 100% of the output of drinking milk, so private farms mainly focus on meeting the needs of dairy processing enterprises. The latter also receive seasonal subsidies.

The Chuvash milk miracle can be explained by the following factors: big rural population; private subsidiary farms; high-quality breeding dairy livestock; high-quality feed; good milk production and processing equipment. However, the comprehensive system of state support measures remains the most important success factor.

Published: December 2023

Polyphenols are potential neuroprotectors that increase lifespan and slow down aging. Red clover (Trifolium pratense L.) is a promising source of biologically active substances. Its extracts contain biochanin A and chlorogenic acid. This research used Caenorhabditis elegans to study the effect of polyphenols extracted from red clover callus cultures on SOD-3 and HSP-16.2 genes, as well as their anti-amyloid potential.

The chlorogenic acid and biochanin A (200, 100, 50, and 10 µM) with a purity of 95% were isolated from callus extracts of T. pratense L. The effect of polyphenols on SOD-3 and HSP-16.2 was assessed after 5 and 2 h of heat stress (35°C), respectively, using C. elegans N2 Bristol as model organism. The neuroprotective potential was measured by counting paralyzed nematodes after 18, 40, and 62 h of incubation.

The research established a dose-dependent effect between the concentration of biologically active substances and the percentage of paralyzed nematodes after 18 h of cultivation. The lowest paralysis phenotype count occurred at a concentration of 200 μM. The activity of 200 μM biochnin A was 1.18 times as high as that of a 200 μM chlorogenic acid solution. Biochanin A solutions increased SOD-3 expression by 3.7 times, compared to the control.

The biologically active substances exhibited relative neuroprotective activity and affected the expression of antioxidant defense gene in C. elegans.

Russian cuisine reflects the identity of its peoples. However, modern nutrition tends to level the multicultural peculiarities of Russian cuisine. This research objective was to identify the effect of packaging and storage time on the quality profile of instant turnip and rutabaga porridges.

The study featured quality indicators of food concentrates. Samples of instant porridges were packaged in sachet bags and cups made of complex materials. They were stored at a 20–25°C and a relative humidity of ≤75% for 8 months. The sensory, physicochemical, and microbiological variables were measured using standard research methods.

After 6 and 8 months of storage, the total sensory assessment for the porridge cups was higher by 1.0 and 2.0 points, respectively, than for the porridge sachets. The cups did not affect the moisture and fat content during storage. The recoverability of the cupped samples was higher by 10.9 and 14.2% after 6 and 8 months of storage, respectively. The mesophilic aerobic and facultative anaerobic microbial count for porridge cups fell by 11.0 times after 6 months of storage and by 3.2 times after 8 months of storage, compared to the sachets. The tests revealed no yeast, mold, Bacillus cereus, coliform bacteria, or pathogenic microorganisms.

Shelf-life had a greater effect on quality profile of instant porridge than packaging. In this research, the recommended shelf life for instant turnip and rutabaga porridges was 6 months. The effect of other packaging types and materials on food concentrates is a promising research direction.

Polylactid Acid (PLA) is a biodegradable polymer made from natural ingredients so it is safe to use for biomaterials. The purpose of this study was to determine the biodegradation characteristics of the addition of chitosan powder and Hydroxyapatite to PLA. There were 4 variations in this study, namely PLA 100 (pure PLA), PLA-chitosan-Hydroxyapatite 94-3-3 (Composite 1), PLA-chitosan-Hydroxyapatite 94-0-6 (Composite 2), PLA-chitosan-Hydroxyapatite 94-6-0 (Composite 3). Samples were prepared using the extrusion method to form filaments, then the filaments were injected with a temperature of 170-190°C and an injection pressure of 5-6 bar. Characterization was carried out using the Immerse Test, FTIR Test, and SEM-EDS Test. The results of the Immerse Test showed an increase in sample mass of 1.04%, 1.1%, 1.05% and 1.14% respectively. FTIR test results did not show any new functional groups in the composite. The results of the SEM test indicated the presence of Na and Cl deposits on the sample surface as evidenced by the results of the EDS test that all samples contained Na and Cl elements. So that the weight gain occurs because the three materials are not chemically mixed which easily separate and cause cavities, these cavities are filled with HBSS liquid.

The hydraulic system is a power transmission system by using the compressive energy of the fluid into mechanical energy to obtain a power greater than the initial power released. The press machine is one of the pieces of equipment that apply the hydraulic system. In the process of making laminated bamboo, the bamboo gluing technique is assisted using a press machine. Based on observations, the press machine used is a manual press machine, so the pressing process is not efficient. This study aims to increase the effectiveness of pressing laminated bamboo. The results of the study found that the press machine has 4 hydraulic cylinders so the pressing process can be carried out at several points simultaneously. The results of the hydraulic system analysis diagram show hydraulic cylinder moves in 16,9 seconds with a pressure of 100 bar, so the pressing process is fast. Mathematical calculations produce data, a hydraulic gear pump with a displacement of 13 cc/rev, electric motor power of 3,7 kW, hydraulic cylinder diameter of 63 mm, cylinder rod of 35 mm, rod of 400 mm, and a hydraulic tank capacity of 12 liters.

The corrosive coastal environment will result in a high corrosion rate for any equipment installed there. This is due to the constant exposure to saltwater, high humidity levels, and strong winds. Therefore, it is crucial to use corrosion-resistant materials and regularly maintain the equipment to ensure its longevity in such an environment. One method to reduce the rate of corrosion is to pay close attention to the manufacturing parameters of these components, one of which is the face milling process. The aim of this study is investigating the effect of face milling process with different dept of cut using minimum quantity lubrication method with corn oil as a renewable vegetable cutting fluid. In this study AISI 316L stainless steel was face milled using HAAS VF-2 CNC machine. The depth of cut is varied between 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm. The results demonstrated that the greater the depth of cut, the greater the surface roughness value that will be generated. It is resulting in increment in the corrosion rate value.

Corrosion of metals is inevitable. One of the factors that affect corrosion is environmental conditions that contain pollutants like SO2, NO2, and Cl- which are found in many industrial and seaside areas. Surabaya is an area that has 2 types of conditions. In addition, Surabaya is the capital of the province where infrastructure development is running rapidly. Thus, this study maps the level of atmospheric corrosion in five areas in Surabaya by collecting corrosion rate data for 4 months with weight loss method using AISI 1020 Steel and SK5 Steel as test metals. XRD and SEM-EDX tests were conducted to compare the corrosion results. The average corrosion rate of low carbon steel was 0,6561 mpy and high carbon steel was 1,2523 mpy. The results concluded that the high level of atmospheric corrosivity of low carbon steel is in Sukomanunggal, Bulak, Rungkut, Pakal, Krembangan, and Bubutan sub-districts. The medium level is in Tegalsari, Gubeng, Tenggilis Mejoyo, Karang Pilang, Jambangan, Sawahan, and Dukuh Pakis sub-districts. The low level is in Lakarsantri, Mulyorejo, Simokerto, Sambikerep, Genteng, and Wonokromo sub-districts. Meanwhile, high atmospheric corrosivity levels for high carbon steel are in Krembangan, Karang Pilang, Bulak, Tenggilis Mejoyo, Pakal, and Jambangan sub-districts. The medium level is in Rungkut, Sawahan, Bubutan, Wonokromo, Tegalsari, Sukomanunggal, and Lakarsantri sub-districts. The level is in Dukuh Pakis, Genteng, Gubeng, Simokerto, Sambikerep, and Mulyorejo sub-districts.

Biomaterials are crucial for bone implants due to their biocompatible and inert nature, ensuring no adverse effects within the human body. Titanium is renowned for its exceptional corrosion resistance. This research aims to analyze the impact of annealing holding time and pH of synthetic body fluid on the hardness and corrosion rate of titanium. The annealing process was performed at 700°C, with holding times of 30, 60, and 90 minutes. As an electrolyte medium, a Hanks' solution with pH variations of 4, 6, and 8 was used and maintained at 37°C. Potentiodynamic corrosion testing demonstrated the lowest corrosion rate in specimens treated with 30 minutes of annealing at pH 8, measuring 0.32 x 10-2 mmpy. The 30-minute annealing exhibited the lowest corrosion rate, which was confirmed by Electrochemical Impedance Spectroscopy (EIS) results showing a higher Rp value, indicating a lower corrosion rate. This is attributed to the presence of a passive Rutile TiO2 layer formed during the annealing process, as confirmed by X-ray Diffraction (XRD) analysis. Metallography observations indicated that the microstructure of untreated specimens consisted of α and β phases. Scanning Electron Microscopy (SEM) analysis of specimens annealed for 30 minutes revealed an oxide layer on the surface without any visible pores. However, an increase in annealing holding time led to the formation of pores, particularly noticeable after 90 minutes of annealing. The presence of pores in the oxide layer resulted in an increased corrosion rate with longer annealing holding times. Conversely, hardness testing demonstrated that longer annealing holding times resulted in higher hardness values.

Published: December 2023

Solid particles have a higher thermal conductivity compared to a fluid. Therefore, it is a common practice to disperse solid particles inside a base fluid to increase its thermal conductivity. The particle-dispersed fluid is called a thermal fluid. Thermal fluid, such as a coolant, is widely used as a heat transfer fluid. Several types of particles can be used to increase the thermal conductivity of the fluid, i.e., metallic particles, metal-oxide particles, or even carbon-based particles. In this research, a carbon-based particle was used as the dispersed particle. The particle was obtained by processing electronic waste, specifically Printed Circuit Board (PCB). The PCB was pyrolyzed for variable duration at 15, 30, and 45 minutes to increase the carbon content. After pyrolyzing, the particle was milled to reduce its size. Subsequently, the PCB particle was added to distilled water. Sodium Dodecylbenzene Sulfonate (SDBS) was added as a surfactant to increase fluid stability and prevent particle agglomeration. Thermal conductivity was improved by up to a 13% increase at the 15-minute pyrolysis. Adding SDBS surfactant also improves the thermal fluid's stability to -29,1 mV. The fluid's viscosity was slightly increased up to a maximum of 0.984 mPa.S.

Authors: Wahjudi Ari , Widodo Agung Sugeng
Published: December 2023

Polymer matrix composite (PMC) is widely applied in structural engineering mainly due to its high strength-to-weight ratio. Of many benefits, the transportation industry uses this type of material mainly due to its high strength-to-weight ratio. In many cases, this strength-to-weight ratio is higher than aluminum or steel base materials. Its manufacturing and fabrication, however, are challenging. For this reason, destructive and non-destructive tests to control product quality during the manufacturing process are worked out. The non-destructive test delivers many benefits since the finished product does not. This paper discusses the benefits of polymer matrix composite application in the structural engineering. In addition, this work also outlined the key parameters and comparison of various non-destructive tests applied for the PMC.

Authors: Gupta Ashwerya , Savita Ubba
Published: December 2023

Advanced technologies such as smart phones and 4G internet have created more opportunities for e-shopping. Individuals are switching their purchases from traditional to digital with the help of electronic commerce. The customer usually evaluates a product by reading other user recommendations on blogs, online sites, and some other social media platforms, commonly termed as eWOM (electronic word of mouth). Reviews and ratings on the internet influence a traveler's decision to reserve an accommodation. The research study examines the influence of eWOM credibility on the purchase intention. The research also examined the role of trust and perceived risk as mediating factors between eWOM credibility and purchase intention. The Questionnaire study was carried on 687 individuals over the age of 18. PLS-SEM was used to examine the data. The eWOM credibility significantly impacted traveler purchasing intentions. The mediator in the relationship between eWOM credibility and purchase intention was trust, not perceived risk. The study recommends that marketers validate the source of information and prioritise the reviews that are perceived as more credible and establish a favourable intention towards online booking.
Exploring Wellbeing through Job Crafting and Meaningful Work to Promote Sustainability in the Backdrop of Indian Ancient Wisdom
Authors: Tripathy Mitashree , Tripathy Saswati , Mishra Itishree
Published: December 2023

Today, the nature of an ever-competitive business environment has become both dynamic and an essential characteristic of globalisation. Constant shift in processes, communication and interdependence, indeed, sustainability in the functioning of any organisation has become an ever-augmenting trend. Organisations although adopt several practices to achieve sustainability, the question is do they truly, achievesustainability? Studies claim sustainability at workplaces entails in reducing company’s ecological footprint, conserving natural resources and taking care of the employees. Surprisingly, in comparison to the former two, the later has been highly ignored. The modus operandi towards achieving productivity and performance may have been successful but the wellbeing of the employees in the organisations is still at stake. Many organisations around the world have implemented wellness programs for the well-being of their employees; however, whether every individual is benefitted through such programs is still a concern. One may assume that such programs do not serve any meaning specifically towards individual level development. Few studies also state that an employee’s well-being is always an outcome of job crafting and as an outcome variable, well-being leads to organisational excellence. However, the current study argues that well-being acts as a mediator between job crafting and sustainability. If employees get motivated to do beyond their job roles through job crafting, a lot of meaning can be derived out of their work leading to high performance and a sustainable environment and if well-being acts as a mediator between the two constructs, achieving sustainability will be faster and more convenient. Well-being of an employee is the most sought-after construct and certain for sustainability. Also mentioned in the Equality Act 2010 any deviation in the process of attaining wellbeing is subjected to disease or disability leading to a stigmatized society. Similar ideas are also mentioned in Indian ancient wisdom. Blending, the theories from philosophy, management, law and ancient wisdom through an interdisciplinary approach, the current paper proposes a conceptual model while establishing a relation between virtues, job crafting mediated by wellbeing and moderated by meaningful work to achieve sustainability.
Vendors Capability: A Way for Winning the Contract in a B2B Relationship
Authors: Saha Sumit , Joshi Kunal
Published: December 2023

A Business-to-Business commercial (B2B) transaction is different from normal retail transactions with customers. Organisations engage with each other and vendors in a specific manner in a B2B purchase environment. Organisations, big or small, spend money to keep up with their business operations. This requires them to deal with many other business units called vendors/suppliers to help them with necessary input resources for their business operations. In B2B transactions, organisations deal with each other to purchase goods and services. These associations work on long-term business relationships. The vendor organisations hire sales teams and relationship managers to work with the client organisation in order to maintain healthy business relationships. It is a point of debate whether the relationship that exists between the vendor and the client is because of the personnel who is responsible for the relationship or is it the vendor organisation as a whole that has built its capability and experience over the years has been successful in maintaining business relationships with the client. A client who engages with a vendor will have certain criteria for selection and engagement with a vendor. With this view, we have decided to study this phenomenon by comparing the two factors – sales person’s relationship and vendor’s capability and check which of the two factors influences the awarding of contracts from the clients. Purchase is more process driven it evaluates the vendors strongly on their capability to deliver on the purchase terms. The data analysis and the hypothesis testing results obtained indicate that evaluating vendors by their capabilities for awarding contracts is a more pragmatic way of supplier selection.
Testing the Hedging Effectiveness of Gold Derivative Market in India
Authors: Khindri Ritima
Published: December 2023

The purpose of this article is to estimate the hedging effectiveness of the Indian Gold Derivative Market from both the statistics of Static hedge methodology of Vector Error Correction Method and Time-Varying hedge methodology of DVEC-GARCH, covering the time span of 1st April 2005 till 31st March 2019, to account for any difference existence in both. The study is conducted to judge the performance of gold futures as a tool of risk management. The result reveals the fact that hedging effectiveness from both the methodologies are found to be 35%. The reason behind low hedging efficiency might be due to the fact that gold itself is used as a hedge instrument and always in demand by the Indian investors for varied reasons as well as its accessibility in various forms (Gold ETFs and Gold Bonds issued by Government). The hedgers’ participation may be less as compared to speculators with respect gold future hedging. The results of phase-wise analysis, that is, before crisis (2005–2007), the hedging efficiency comes out to be 26%, during the crisis (2008–2012) 38.7% and after the crisis (2013–2018) 40% from both the static and dynamic hedge ratio models. The results showed that with the outbreak of Global Financial crisis in 2007–2009 and European debt crisis in 2010–2012 and thereafter, gold futures are increasing use as a risk management tool, but still at a minimal level.
Environmental Accounting as a Tool for Sustainable Development: An Empirical Study on Large Scale Companies in Gujarat
Authors: Prajapati Chhaya , Shah Kamini
Published: December 2023

The disclosing of environmental accounting information is a crucial step towards achieving the aim of “carbon emission.” The corporate sector’s role is higher in polluting the environment as well as the extravagant use of natural resources. Many steps have been initiated by the Indian government in favour of environmental protection and sustainable development. PM Modi introduced India’s “Panchamrit” to achieve the net zero emissions target by 2070. In this regard, this study has been undertaken to examine the environmental variable disclosure score (EVDS) by the selected thirty (30) companies in the state of Gujarat. Only large-scale companies are listed on National Stock Exchange and Bombay Stock Exchange stock exchanges. Only high-polluting companies which fall in the red category (as per Gujarat Pollution Control Board) that only selected for the study. Earlier studies focused on revealing the environmental information of the companies at the India level but very few studies have been observed at the state level. Hence, this research bridges the gap by examining the impact of audit quality on EVDS, the Business Responsibility Report (BR Report) score on EVDS, and analysing the difference between the large-cap, mid-cap and small-cap companies in EVDS.

Authors: Shroff Sumita Jagdishprasad , Paliwal Udai Lal
Published: December 2023

The present study assessed the status of the financial literacy (FL) levels and examined its impact on the investment decisions of the investors from the cities of Ahmedabad and Vadodara in Gujarat state. We measured FL using a multi-dimensional construct of financial behaviour, attitude and knowledge. Investment decisions were analysed taking the six proxies – neutral information, personal financial need, macroeconomic indicators, accounting information, advocate information and firm image. The study revealed a high level of FL among the respondents with 62.50% of the respondents being highly financially literate and the remaining having a comparatively lower degree of FL. Though, respondents exhibited a higher level of financial literacy, they still lacked required degree of understanding of advanced financial and investment topics. Using simple linear regression, we found that investors’ investment decisions were significantly positively impacted by their levels of FL.

Authors: Mukherjee Tutun , Halder Hrithika , Sen Som Sankar
Published: December 2023

This article endeavours to investigate the impact of corporate governance practices on financial performance and corporate growth considering a sample of leading 88 non-financial companies listed on the National Stock Exchange for the period 2011–2020. Using static panel data technique, the results show that the proportion of female directors in boardrooms maintains a significant and positive association with corporate financial performance, while board independence and corporate financial performance are associated negatively. On the other hand, no noticeable relationships are found between board size, CEO duality, and corporate financial performance. Moreover, the results show that the proportion of female directors on boards and corporate growth are associated positively, whereas board size, board independence and CEO duality appears to have no significant associations with corporate growth. The results are re-examined by employing several tests, including sensitivity analysis and alternative model specifications and are held robust. The empirical findings offer considerable impetus for corporate policy makers or regulators to set up the needed policies and regulations in the light of strengthening corporate governance practices.

Authors: Garcia Paula Caroline , Bae Julie , Risso Pariz Juliana
Published: December 2023

This study reports a case of abdominal flaccidity after three pregnancies in which smooth and spiculated polydioxanone threads were used, a technique not yet described in the literature to treat this complaint. The patient was followed up for 90 days. However, there was an improvement in the opening of the umbilical fold, skin tone, dermal density, and tissue flaccidity after 60 days. During this period, the patient declared that she was completely satisfied, and discharge from treatment was established. With this case report, we can conclude that the combined therapy of PDO thread screws and spiculated PDO threads (Sculpt®) resulted in very expressive outcomes regarding the quality of the skin, promoting a visible improvement in tissue flaccidity.

Objective: to understand the experiences of cancer patients based on the diagnosis and the strategies adopted. Methods: this is a qualitative and transversal research, exploratory and descriptive. The sample consisted of 10 women with cancer assisted by a support association for cancer patients in João Pessoa/PB, selected by non-probabilistic convenience sampling. To collect data, a sociodemographic and health questionnaire was used, as well as a semi-structured interview based on the life history method. Sociodemographic data were analyzed using descriptive statistics (frequency and percentage), and data from the interview were analyzed using the Thematic Content Analysis technique proposed by Bardin. The average age of the women was 61.8 years. Four categories and 12 subcategories emerged. Results: the diagnosis of cancer caused negative impacts on the lives of patients and their families. Having a support network is an essential coping strategy used by patients due to the suffering caused by cancer. Conclusion: The importance of strategies for coping with the suffering of cancer patients was highlighted, especially concerning the support network, this being the most prominent category among all those found.

Published: December 2023

Classification algorithm is a supervised learning technique that is used to identify the category of new observations. However, in some cases, quantitative and qualitative data must be used together. With this approach, we tried to overcome the problems encountered in using quantitative and qualitative data together. In this paper, we model a new classification technique by converting all types of data to binary data because in real world, data are classified in different types such as binary, numeric or categorical. By this way, we develop a more accurate and efficient mixed data binarization approach for multi-attribute data classification problems. First, we determine the classes from available dataset and then we classify the new instances into these predetermined classes by using the new proposed data binarization approach. We show how each step of this algorithm could be performed efficiently with a numeric example. Then, we apply the proposed approach on a well-known iris dataset and our model show promising results and improvements over previous approaches.

Gerek barındırdığı nüfus gerekse hemen hemen her sektörde lider konumunda olması İstanbul’u ekonomik ve demografik açıdan Türkiye’nin en önemli ili kılmaktadır. Kenti etkileyecek şiddetli bir depremin yol açacağı can kaybı ve maddi hasar ile kısa ve uzun vadeli ekonomik etkiler kamuoyu gündemini neredeyse her gün meşgul etmektedir. Konunun önemi bu derece açık olmakla birlikte olası bir depremin ekonomik etkileri hakkında uzman görüşü dışında bilimsel yöntemlere dayalı bir çalışma mevcut değildir. Bu çalışmada olası İstanbul depreminin İstanbul ekonomisi üzerindeki etkileri sistem dinamiği yaklaşımına dayalı bir benzetim modeli ile incelenmektedir. Önerilen model temel olarak üretim ve harcama yöntemiyle gayri safi yurtiçi hasıla (GSYH) hesaplanmasında kullanılan değişkenlerin aralarındaki karmaşık ve çok yönlü nedensellik ilişkilerini yansıtmaktadır. Bu değişkenler temel olarak üretim tüketim dengesi, yurtiçi talep, ithalat, ihracat, sektör büyüklükleri, deprem sonrası toparlanma süresi gibi başlıkları ifade etmektedir. Oluşturulan temel model üzerine senaryo analizleri gerçekleştirilmiş, farklı şiddetlerde meydana gelebilecek depremlerin ekonomik etkileri analiz edilmiştir. Elde edilen sonuçlara göre depremin ardından toparlanmanın uzun süreceği sektörler olmakla birlikte yoğun talebin bulunduğu sektörlerde üretim-tüketim dengesinin yeniden sağlanmasının çok uzun sürmemesi beklenmektedir. Bilindiği kadarıyla bu çalışma literatürde sistem dinamiği yaklaşımıyla afet ekonomisi konusunu birleştiren ilk çalışmadır.

Bireysel ve kurumsal yatırımcılar açısından portföy oluşturmasındaki temel amaç yüksek getiri elde etmektir. Yatırımcılar açısından, varlıkların getiri ve risk yönlerini kapsamlı bir analiz yaparak minimum risk ve maksimum getiriyi oluşturacak şekilde bir portföy ortaya koymak gereklidir. Portföy optimizasyonu alanında, literatürde temel olarak iki yöntem kullanılarak portföy oluşturma çalışmaları yapılmıştır. Geleneksel portföy yönetimi, sektörel çeşitlendirme esasına dayanmaktadır. Modern portföy yönetimi ise matematiksel modeli esas alan yenilikçi bir yaklaşımdır. Bu çalışmada, modern portföy yaklaşımları temelli simülasyon metodu kullanılarak portföyler elde edilmiştir. BİST 30’da yer alan şirketlerin Piyasa Değeri / Defter Değeri (PD/DD) ve Fiyat – Kazanç (F/K) oranlarını kullanarak Monte Carlo simülasyonu metodu ile yatırımcıların risk algısına göre portföyler elde edilmiştir. Çalışma sonucunda, portföyün en yüksek yüzdesini oluşturan hisselerin PD/DD değerinin daha düşük olanlar olduğu gözlemlenmiştir. F/K değerlerinin ikinci derece önemli faktör olduğu görülmüştür.

Görünür ışık haberleşme sistemleri aynı anda hem aydınlanma hem de veri iletimi sağladığından karartma seviyesinin ayarlanması önemli görülmektedir. Karartma seviyesini ayarlamak için modülasyon tabanlı yöntemlerden birisi olan değişken darbe konum modülasyonu yöntemi tercih edilmektedir. Sinyalin görev periyodunun değiştirilmesine ek olarak analog olarak güç seviyesinin değiştirilmesi karartma seviyesini değiştiren yöntemlerden birisidir. Bu çalışmada değişken darbe genlik konum modülasyonu (VPAPM: Variable Pulse Amplitude Position Modulation) yönteminin Bit Hata Oranı (BER: Bit Error Rate) performansı alıcı-verici arasındaki mesafe dikkate alınarak incelenmiştir. Ancak, sıralı düşük veya yüksek güç yayılımının yapılması durumunda hedef karartma seviyesine göre gerçek karartma seviyesinin değişimi değerlendirilmiştir. Ayrıca, sıralı düşük veya yüksek güç seviyesinde yapılan iletimlerde elde edilen bit hata oranı ile ortalama güç seviyesi için hedef karartma seviyesinde yapılan iletimlerde elde edilen bit hata oranı arasında bir karşılaştırma yapılmıştır. Karşılaştırma sonuçlarına göre sıralı yüksek güç seviyesinde yapılan iletimlerde elde edilen bit hata oranı performansı hedef karartma seviyesinde yapılan iletimlerde elde edilen bit hata oranı performansına göre daha iyi bir sonuç veriyorken, sıralı düşük güç seviyesinde yapılan iletimlerin hedef karartma seviyesinde yapılan iletimlere göre daha düşük bit hata oranı performansı verdiği görülmüştür.
