Authors: AJIK-CERBAS Qhaironessia H. , JUMDAIN Rosita T. , TAHILUDDIN Albaris B.
Published: October 2022

Meatballs made from fishery products such as fish, shrimp, and squid are among the popular street foods in Asia. To meet the increasing demand for these street foods, there is a need to develop/formulate new balls out of fishery products. Hence, in this study, crab balls from blue swimming crabs (Portunus pelagicus) were formulated and standardized using three formulations (meat and binder ratio): Formulation A (50:50), Formulation B (60:40), and Formulation C (70:30). Sensory attributes such as flavor, color, texture (juiciness and chewiness), and general acceptability of the three formulations were evaluated by sensory panelists. Selected formulation was further analyzed in terms of shelf-life testing and comparison with the existing commercial squid ball. Consumer testing was also done to determine the feasibility of the formulated crab ball. Results revealed that Formulations B and C received the highest overall score of sensory attributes (p

Authors: Sasikumar A. , Gopi S. , Mohan Dhanesh G.
Published: October 2022

The aluminium alloys 5052 and 6082 are extensively used in manufacturing lighter structural members, having improved strength and resistance to corrosion. Magnesium (Mg) and Chromium (Cr) powder were the filler materials selected for enhanced corrosion protection properties in this investigation. Friction stir welding (FSW) process parameters viz., spindle speed, welding speed, shoulder penetration, the centre distance between the holes and filler ratio are used to forecast the minimum corrosion rate from different weld regions of AA5052-AA6082 dissimilar joints. Response surface methodology based on a central composite design was used to evolve the mathematical models and estimate dissimilar FSW joints’ corrosion rates. Response optimization shows that the minimum corrosion rate was achieved by the welding parameters of spindle speed 1000 rev/min, welding speed 125 mm/min, holes spacing of 2 mm and filler ratio 95% of Mg and 5% of Cr.
Leakage control of urban water supply network and mathematical analysis and location of leakage points based on machine learning
Authors: Liang Junqing , Kong Xiaoxiao
Published: October 2022

In order to solve the common problems of high leakage rate of urban water supply network and controlling water supply enterprises, a multi index system of leakage evaluation is proposed. The first step in leakage assessment is to recommend non profitable water volume, rather than just based on the percentage of leakage rate (the calculation mode of percentage is easily disturbed by the change of water volume); Advanced indicators also need to consider factors such as pipe network conditions, pressure and the number of user connections; If possible, it is recommended to calculate the leakage index (ILI) of water supply network in line with international standards, and through this index, determine the leakage classification of water supply system according to the target matrix provided by the world bank, so as to formulate corresponding leakage control countermeasures, and finally form a set of leakage performance evaluation system of urban water supply system combined with the actual situation of our country. Experiments have proved that among users with large caliber and large water volume, the promotion of electromagnetic remote transmission water meter should be strengthened to improve the metering capacity of water meter. Since 2014, non household meters above Dn40 in the company's new household installation project have adopted electromagnetic remote transmission water meters. At the same time, strengthen the remote monitoring and management of large-diameter water meters. Through remote transmission, we can grasp the changes of users' water use in real time, and realize the three-level early warning of sudden change of water volume through the mining of remote transmission data.
Term structure of economic management rate based on parameter analysis of estimation model of ordinary differential equation
Authors: Yang Yi , Arbab Ahmed
Published: October 2022

In order to study the dynamic characteristics of the interest rate term structure of zero-yield bonds in China's bond market, and why China's interest rate term shows such changing characteristics 96-month interest rate structure data at the end of December. Among them, the term structure of interest rates in the securities market is from 1 year to 20 years, and the term structure of interest rates in the interbank market is from one year to 30 years. Analyze the data to find out the basic characteristics of the dynamic change of the term structure of China's interest rate, and find the entire term structure of China's bond market from the perspective of trends. This feature is evident in short-term interest rates in the interbank market, influenced by central bank financial policies. In terms of statistical characteristics, as the yield to maturity of Chinese bonds increases on average, that is, the inclination of the term structure of interest rates increases. The volatility of yield to maturity of short-term bonds is significantly higher than that of long-term bonds, and the volatility of yield to maturity in the securities market is lower than that of the interbank market, mainly because short-term bonds and the interbank market are easily affected by the central bank’s financial policies. Experiments show that the level of inflation rate (PPI growth rate) is an important factor that determines the level of the term structure of interest rates. Inflation rate and interest rate levels are important determinants of skew and curvature factors.
On Solving 0/1 Multidimensional Knapsack Problem with a Genetic Algorithm Using a Selection Operator Based on K-Means Clustering Principle
Authors: Laabadi Soukaina , Naimi Mohamed , Amri Hassan El , Achchab Boujemâa
Published: October 2022

The growing need for profit maximization and cost minimization has made the optimization field very attractive to both researchers and practitioners. In fact, many authors were interested in this field and they have developed a large number of optimization algorithms to solve either academic or real-life problems. Among such algorithms, we cite a well-known metaheuristic called the genetic algorithm. This optimizer tool, as any algorithm, suffers from some drawbacks; like the problem of premature convergence. In this paper, we propose a new selection strategy hoping to avoid such a problem. The proposed selection operator is based on the principle of the k-means clustering method for the purpose of guiding the genetic algorithm to explore different regions of the search space. We have elaborated a genetic algorithm based on this new selection mechanism. We have then tested our algorithm on various data instances of the 0/1 multidimensional knapsack problem. The obtained results are encouraging when compared with those reached by other versions of genetic algorithms and those reached by an adapted version of the particle swarm optimization algorithm.

Authors: Shynkarenko Viktor , Zhuchyi Larysa , Ivanov Oleksandr
Published: October 2022

Semantic checking of railway infrastructure information support data is one of the ways to improve the consistency of information system data and, as a result, increase the safety of train traffic. Existing ontological developments have demonstrated the applicability of description logic for modelling railway transport, but have not paid enough attention to the data resources structure and the railway regulatory support. In this work, the formalization of the tabular presentation of data and the rules of railway transport regulations is carried out using the example of a connection track passport and temporary speed restrictions using ontological means, data wrangling and extraction tools. Ontologies of the various formats data resources and railway station infrastructure, tools for converting and extracting data have been developed. The semantic checking of the compliance of railway information system data with regulatory documents in terms of the connection track passport is carried out on the basis of a multi-level concretization model and integration of ontologies. The mechanisms for implementing the constituent ontologies and their integration are demonstrated by an example. Further research includes ontological checking of natural language normative documents of railway transport.

Authors: Salim Alvin , Tambunan Evelyn Hemme
Published: October 2022

Objectives

Sex education toward adolescent remains the most controversial subject due to the various thoughts and ideas of different values present in society. Nurse educators as parents must exemplify sex education to their children. The aim of this present study was to explore parents’ experience, with nurse educators background to be exact, on how they convey sex education to their children.

Methods

This study is a descriptive qualitative study, and the sample is recruited by using the purposive sampling technique. The qualified participants filled in the informed consent, provided demographic data, and were interviewed. Saturation data were obtained at the 6th interview in this study. The interview is transcribed to find themes and subthemes using conventional content analysis.

Results

We derived 3 main themes: parents’ approach, sex education topic, and children's reaction. Parents’ approach contained 4 subthemes, namely, gender match, parent–child closeness, media, and attitude. Sex education topic included 5 subthemes of bodily autonomy, health and safety, reproductive anatomy, puberty-related changes, and how to maintain healthiness. Children's reaction experiences also included 4 subthemes of uncomfortable, questioning, acknowledging, and laughing.

Conclusions

As a matter of fact, some parents in eastern countries, such as Indonesia, conveyed sex education to their children. Children might have various reactions to that topic, but it is important to keep them safe, especially in reproductive health, regardless of the culture or tradition. Based on nurse educators as exemplifiers, nurses and nursing students might acquire the picture in conveying sex education to adolescents.

Background

The complexity of multiple sclerosis (MS) due to psychological, emotional, physical, family, and social dimensions complicates the care of these patients. MS patients need hospitalizations and long-term care to treat and control the progression of the disease. Therefore, the competence of caring for MS patients is one of the important issues in clinical nursing.

Objective

To explain the dimensions of competence in caring for MS patients.

Methods

This study is a qualitative descriptive study using conventional content analysis method. Field notes and semi-structured face-to-face interviews were conducted on 12 specialist nurses of MS and 3 MS patients from the neurology ward. Participants were selected through purposeful sampling. Data analysis was performed using the approach of Zhang and Wildemuth by continuous comparison simultaneously with data collections.

Results

Data analysis led to the extraction of 2 categories with 5 subcategories. The first category is “unlearned care competence,” with the subcategories as psychological–emotional resilience, psychological skills, and excellent communication skills. The second category is “specialized technical competence,” with the subcategories as up-to-date pathological knowledge and expertise in clinical procedures.

Conclusions

Identifying the competencies of nurses of MS patients is important for educating nurses to provide qualified care and improve MS patient satisfaction. Nursing managers can empower nurses in non-technical areas such as in-service psychology courses and improve professionalism in caring for MS patients by promoting communication and specific clinical skills.

Authors: Castañeda Francisco , Ormazábal Francisco , Cisternas Carla
Published: October 2022

This article analyses the sociodemographic determinants associated with the financial literacy levels of the Chilean population based on three dimensions: (1) knowledge; (2) behaviour; and (3) attitude. The study draws from data of the first and, thus far, the only national survey that has measured financial competency, conducted in 2016 by the Organisation for Economic Cooperation and Development (OECD), funded by the Financial Market Commission (CMF in Spanish) and the Andean Development Corporation (CAF in Spanish). It analyses the impact sociodemographic factors such as sex, age, education, and employment situation have on the financial literacy level of the population surveyed (N = 1.224). For each dimension, logistic regression models were adjusted consistent with the global financial literacy index. This method aimed to calculate, based on these variables, the probability that an individual may possess adequate knowledge, behaviour, and financial attitude. The findings indicate that a person between 30 and 60 years old, with a high education level, who earns a high income, will have a greater probability of possessing an adequate financial literacy level.

Published: October 2022

The objective of this study is to provide insights on whether NZX 50 and sectorial indices of different industries in New Zealand have been impacted differently under the influence of COVID-19 and the measurements that government have taken in responding to the global pandemic. Results indicated that the New Zealand businesses are not immune from this pandemic despite the New Zealand government’s “go hard, go early” measure to eliminate the spread of Coronavirus. Statistical findings show that stock market and sectorial performances between the pre- and post-global pandemic period are significantly different. Most of the industries reported poorer performances except Healthcare and Consumer Staples. In addition, the NZX 50 and sectoral indices reported a significant relationship with the S&P 500 indicating that as the world become more integrated, stock market performances are displaying co-movements while responding to major events.
Social Media Customer Relationship Management and Business Performance: Empirical Evidence from an Emerging Market
Authors: Dogan-Sudas Hatice , Kara Ali , Cabuk Serap , Kaya Kadir
Published: October 2022

The purpose of this paper is to investigate how social media marketing engagement efforts mediate the relationships between CRM and the business performance. We argue that social media marketing engagement efforts used by the companies will enhance the positive influence of CRM on business performance. We used Hunt and Morgan’s (1995) resource–advantage theory (R-A theory) as the theoretical framework for understanding the relationship between CRM and business performance mediated by online social media marketing efforts. Data for the study is collected using face-to-face personal surveys conducted with n=152 top management team members of randomly selected companies across a broad spectrum of industries located in Turkey. The study findings indicate that traditional CRM approach had positive effect on firm performance, but the relationship was partially mediated by the social media marketing engagement (SCRM) activities. The strength of the relationship along with the explained variance improved when SCRM was introduced into the structural model. This study provides additional empirical support for the role of the SCRM in modern organizations. It fills the gap in the literature in shedding light to the value of SCRM in the context of an emerging market environment to realize the full benefits of CRM.
Impact of CSR Expenditure Compliance on Firm Value Using P/B-Roe Valuation Model and Instrumental Approach
Authors: Gupta Pradeep Kumar , Garg Arunesh
Published: October 2022

This paper examines the impact of corporate social responsibility (CSR) expenditure compliance on firm value in the context of the Indian firms by applying instrumental approach of the stakeholder theory and the P/B-ROE valuation model. The study hypothesizes that CSR expenditure compliance will positively affect the firm value. Price-to-book (P/B) ratio of the firm is used as a proxy of the firm value. The sample of firms is selected from NSE-500 Index companies for the period of five years from 2014-15 to 2018-19 and the method adopted is a portfolio grouping approach to form a cross-sectional portfolio regression model. The results reveal that CSR expenditure compliance negatively influences firm value. Thus, instrumental approach which hypothesizes that CSR initiatives improve firm performance is not supported. However, to form a cross-sectional portfolio regression model by using portfolio grouping approach is found to be more appropriate than the individual cross-sectional regression model.
Improving Performance Feedback Perceptions Through Motivating Language Use
Authors: Doreen Hanke , Albi Alikaj , Prity Patel
Published: October 2022

This study examines the link between leader motivating language and follower performance feedback perceptions It also explores whether follower/leader gender compositions moderate this relationship. Results show that a follower’s performance feedback perceptions benefit from a leader’s use of motivating language. This relationship is further positively moderated by the presence of certain follower/leader gender matches and mismatches. The results provide support for a stronger use of motivating language in diverse workforces. This characteristic gives motivating language the potential to support diversity in organizations. Implications of the study’s findings and future avenues for research are discussed. Considering the increasing need for more effective performance reviews, motivating language might be one of the future tools to increase their positive perceptions and ultimate success, especially in a diverse workforce.

The study aimed to analyze the impact of corruption on economic growth, for a sample of 131 countries, during the year 2018. Three indicators of corruption were used. The economic growth variable was an ordered variable that arranges the country’s income into four categories of income. A set of control variables was also used. The relationship between the variables was analyzed using Ordered Probit and Ordered Logit Models. Three model parameters were estimated using STATA software. The results of the study showed that the three indicators of corruption had a negative and significant impact on the income levels of the studied countries. The results also showed that each income level has specific threshold values for corruption indicators. The higher the level of corruption in a country than that threshold. The greater the need for an effective anti-corruption policy. And allocate more funding for its success.
The Objectives of the Europe 2020 Strategy and Romania’s Achievements
Authors: Paul Lucian
Published: October 2022

The Europe 2020 strategy comes amid a deep economic crisis and long-term challenges: globalization, pressure on resource use and climate change. The Europe 2020 strategy seeks solutions to the 2008 crisis through action at an European level, based on the broad coordination of economic and fiscal policies among member states. The solutions adopted by the European Commission involve a number of common objectives, which do not take into account the level of development of each Member State. However, the Commission leaves it to Member States to set a national level of targets which may differ from what has been set at the European level, depending on their needs. This strategy has been implemented at Member State level with the help of the National Reform Programs and monitored throughout the European Semester. Romania has established its own values for all the objectives of the “Europe 2020” Strategy, and the results it obtained require an analysis.

Published: October 2022

This study examines the effect of sustainability reporting on financial performance from economic, social and environmental dimensions. The research sample consisted of 31 companies that published sustainability reports during 2015-2019. The results showed that the economic and environmental dimensions showed a negative effect on ROA. This means that companies that disclose economic and environmental performance will reduce the achievement of ROA. while disclosure of social performance will not affect ROA. This study proves that the theory of stakeholders is not sufficient to meet the achievement of profitability and companies need to look at the substantive aspects of sustainability reporting.

Published: October 2022

The growing importance of creative knowledge workers as a resource of particular significance for the growth of organizations is becoming one of the greatest challenges of the knowledge-based economy. An organization that employs knowledge workers, is an organization that can develop itself. One characteristic of knowledge workers is that they are creative and always driven by a desire for change. Therefore, wherever they see an opportunity to develop or a problem that can be solved implicating a lower cost it represents an opportunity for the organization. In the end, if the organization knows how to cherish its knowledge workers, will have an advantage on the market that it activates, but also, will be easier for it to attract more knowledge workers. The purpose of the paper is to familiarized the readers with all these concepts, how can be influenced and stimulated knowledge worker productivity, for better understanding of their importance for modern organizations. We are aware that only the presentation of the theory of a complex economic concept is not enough, that s why we realized and present in the paper a case study about how much employees know about knowledge worker, employee satisfaction and employee productivity, constructed using information gathered from people around the globe throughout a survey.

Islamic banking is an essential element in the development and establishment of Indonesia’s economy, for that it is crucial for management to have a good marketing strategy to be sustainable. Thus, this research aims to explore the route of consumer loyalty by emphasizing religiosity, intimacy, and service quality as the factors of consumer satisfaction of Indonesian Islamic banking. This study applies a structural equation model (SEM) to analyze data collected from 308 Islamic bank consumers in Indonesian Islamic communities and Islamic institutions. The empirical results show that the service quality dimensions (PAKSERV scale); tangibility, reliability, assurance, sincerity, personalization, and formality play an essential role in increasing consumer satisfaction and consumer loyalty. There is no direct relationship between consumer religiosity and consumer loyalty, whereas consumer intimacy and service quality have a direct positive impact on consumer satisfaction and consumer loyalty. Furthermore, consumer satisfaction act as fully mediating role between service quality and consumer loyalty. Practically, the findings of this study can be used by Islamic banking management to focus on modifying service quality by emphasizing the dimensions of sincerity, personalization, and formality. And stay focused on the customer relationship with the company
Fostering Innovation in Romania. Insights from the Smart Specialization Strategies
Authors: Claudia Ogrean , Mihaela Herciu
Published: October 2022

Innovation has invariably been a precursor to development and competitiveness, while creating (at least temporary) barriers to differentiate between its leaders and its laggards. Although Europe is ranked the second most innovative region in the world, the EU faces a significant innovation divide, that is attenuating its footprint on the global competitiveness arena and weakening its mission of enhancing the wellbeing of all Europeans. The EU’s goal of the twin (green and digital) transition brings innovation (in its broadest sense) in the spotlight, while the EU Cohesion Policy (aiming to remedy the disparities between countries and regions) heavily relies on the smart specialization strategy as main methodology for reinforcing national and regional innovation eco-systems. In this context, the objectives of the paper are: (1) to explore Romania’s innovation performance (and profile over time) within the EU and identify the strengths and weaknesses of Romania’s innovation ecosystem – based on the analysis of the European Innovation Scoreboard (EIS) data; (2) to examine and assess how Romania and its eight development regions address the innovation challenges through their smart specialization strategies 2021(2)-2027 – based on the content analysis of the (national and regional) S3s using QDA Miner v6.0.

Published: October 2022

The present study, it was aimed to determine the effect of antioxidants added to culture media on blastocyst development rates in in vitro embryo production. The material of the study consisted of oocytes collected from the ovaries taken from the slaughterhouse. Cumulus oocyte complexes (COC) were collected and classified under a stereomicroscope. Oocytes included in the study were subjected to maturation and fertilization stages. Probable zygotes were transferred to the culture (IVC) containing antioxidants (L-ergothionine 100 μM (n: 163), Vitamin E 100 μM (n: 151) Cysteamine 50 μM (n: 154) and were cultured in a tri gas incubator (Hera Cell- 6% O2%, 6%CO2, 88%N). Blastocyst rates and embryo quality were determined on the 6th and 7th days in culture medium. Differences in IVMFC stages were evaluated by chi-square test. 966 oocytes were collected from 162 ovaries collected from the slaughterhouse. It was determined that the number of oocytes per ovary was 5,96, and the number of A and B quality oocytes was 4.26. It was determined that 655 (94.93%) of a total of 690 oocytes undergoing in vitro maturation were mature. The cleavage rates of the groups were 83.44%; 80.79%; 79.87%, and 83.96%, respectively. 140 (21.37%) blastocysts were obtained from 655 oocytes taken into the culture stage and the blastocyst rates in the groups were 33.13%; 8.61%; 7.79%, and 32.62%, respectively. As a result of the study, it was determined that the rates of blastocysts in the L-ergothioneine added the group was similar to the control group, but the blastocyst rates decreased significantly in the cysteamine and Vitamin E added groups. It was thought that this decrease might have been affected by the dose of antioxidants or the adequacy of oocyte development

The antioxidant defense system of the medicinal plant Raphanus sativus L. tuber in terms of total protein content and peroxidase (POX) activity against gray mold disease caused by Botrytis cinerea fungus on Vicia faba L. (bean) leaves was analyzed spectrophotometrically. Stock solutions of distilled water, ethanol and methanol extracts of R. sativus tuber were prepared with dimethyl sulfoxide (DMSO). A spore suspension of 105 spores/mL of B. cinerea was prepared. The leaves of V. faba were treated with distilled water (negative control), only DMSO, only B. cinerea (positive control), only extract treatment (distilled water, ethanol and methanol extract) and B. cinerea applications after extract treatments. The leaves were extracted in accordance with the methods to be analyzed. Analyzes of the supernatants obtained from the extracts were performed spectrophotometrically. As a result of the research, it was determined that the total protein content increased in the extract:fungus treatment groups compared to the group treated with distilled water (negative control). However, it was determined that it decreased in generally compared to the group that was only treated with fungus (positive control). POX activity was found to be increased compared to the negative control group. Total protein content and POX activity increased in only the extract groups compared to the negative control group. The highest POX activity was obtained from the treatment of 10 mgmL distilled water:fungus. In this respect, it can be stated that the best antioxidant activity among the extract:fungus treated groups is 10 mg/mL distilled water:fungus treatment. From this point of view, it can be stated that R. sativus distilled water, ethanol and methanol extracts give an antioxidan defense response in V. faba leaves.

Both pools were covered with a polyethylene at a height of 1 meter from the ground. Lettuce seedlings were transplanted into pools filled with water and a week later Liquid Vermicompost (LVC) and Hoagland Nutrient Solution (HNS) were added to the growing media according to the treatments. The trial was set up in a Randomized Block Design (RBD) with 3 treatments and 3 replications in both of the lettuce varieties. 1. Application: HNS +LVC; 2. Application (HNS); 3. Application (LVC). Lettuce leaves were harvested 84 days after the LVC and HNS applications and prepared for analysis. In this research, in order to determine the impact of liquid vermicompost on Iceberg and Lolo rosso lettuce varieties total yield, marketable yield, the number of leaves discarded, root length and root weights were determined after harvested plants. In both of the lettuce varieties, results indicated that the highest marketable yields were obtained in the first treatment (HNS+LVC). The highest root length and root weight were also determined in the first treatment. It can be concluded that adding liquid vermicompost (100 ml / 100 L water ratio) to the growing solutions of Iceberg (Head lettuce) and Lolo rosso (Lactuca sativa) lettuce varieties, high performances can be obtained.

Cornus mas L. (Cornaceae) and Rosa canina (Rosaceae) are plant species growing in Turkey naturally. The fruits of both plants are rich in anthocyanins, phenolics and vitamins and used for production of traditional foods such as syrup, juices, jam and marmalade. The antimicrobial activity and some bioactive contents of extracts obtained from fresh and dried fruits of C. mas and R. canina were investigated in this study. Also, as a result of GC-MS analysis of fresh and dried fruit extracts of C. mas and R. canina, varying numbers of fatty asits were determined. The major fatty asits in the extracts of both species were determined as varying proportions of palmitic, oleic and linoleic asit. Bioactive substance contents and antimicrobial activities were varied according to the extraction method. The methanolic extraction (dried fruits) so was more productive than that of water (fresh fruits). Antimicrobial activities of the plant samples were tested by well diffusion assay using 8 bacteria and one yeast. According to the results, both of the plant samples showed an inhibition on whole test microorganisms in varying range but B. subtilis and MRSA.

Climate change is one of the biggest global environmental problems faced by mankind in recent times. Therefore, determining the knowledge and awareness levels of individuals on this issue is very important in terms of contributing to the solutions to be developed in the fight against climate change at the local level. In this study, it is aimed to determine the approaches, consciousness and awareness levels of Kırşehir Ahi Evran University students and local people about climate change in Kırşehir. The main material of the research consisted of primary data obtained from 250 face-to-face surveys applied to students and the public. Related literatures are also secondary data. The survey questions include questions about the individual characteristics of the person (gender, age, education level, job), climate change awareness level, and the effects of climate change on agriculture and water resources. The obtained data were analyzed using SPSS 26.0 statistical package program. In the evaluation of the data, descriptive statistics, frequency tables and graphical representations were used. As a result of the analyzes performed using the Kruskall-Wallis test, it is seen that there are statistically significant differences between the education groups in the variables of climate change awareness level and climate change risk perception level (P0.05), and there was a statistically significant difference between the occupational group averages in the climate change risk perception level (P

This study was carried out to determine changes in hydraulic conductivity of a saline sodic soil subjected to different wetting-drying cycles and treated wastewater after stabilized sludge sewage and gypsum application. In a factorial experimental design, the study was conducted with three replication by using 3 treatment sewage sludge doses (50, 100 and 150 t ha-1), 3 wetting-drying cycles (0, 7 and 14 days) and 2 different water types (fresh water and treated wastewater). The hydraulic conductivity values of the saturated saline-sodic soils were measured at 2, 12 and 24 hour intervals by using a constant level ICW laboratory permemeter. The increase in the applied treatment sludge dose significantly affected the hydraulic conductivity value of the soils and significantly depending on the measurement range. It was determined that irrigation waters have different properties caused a significant change in the hydraulic conductivity value of the soils, with measurements made at intervals of 2 and 24 hours. Depending on the measurement interval, it was determined that the increase in sewage sludge doses caused significant effect and very important on the soil hydraulic conductivity. The study results indicated that the application of gypsum and stabilized waste sludge to the soil cause an increase in hydraulic conductivity values. The study results indicated that the application of gypsum and sewage sludge to the soil cause an increase in hydraulic conductivity values of saline sodic soils. The study results also showed that treated wastewater containing low amount of suspended solids can be used safely for irrigation on the land have saline-sodic soils. The study result also indicated that by applying solid and liquid wastes obtained from treatment units to the saline-sodic soils can be significant contribution in terms of waste management and environmental protection.

A great number of beneficial and harmful microorganisms colonize the human gastrointestinal ecosystem. Of these, beneficial gut bacteria have numerous and significant functions. The use of probiotics, paraprobiotics, and postbiotics to alter the gut microbiota has attracted recent attention as an imbalance in the gut microbiota can lead to the development of various diseases (such as type 1 diabetes, cancer, and others). These concepts are generally confused with each other. The paraprobiotic concept includes the use of killed microbial cells, while postbiotics refer to metabolic products of live microbial cells. In this review, it was aimed to give information on probiotics, paraprobiotics, and postbiotics approaches. In this context, this review provides knowledge about the microorganism and metabolites found in these groups, their action mechanism, clinical characteristics, and potential therapeutic applications.

Sweet sorghum, which is one of the bioethanol sources, has been increasing in importance in recent years. It is used in the production of bioethanol due to the high content of sugar in it. This study were carried out at Ege University, Faculty of Agriculture, Department of Field Crops, Izmir/Turkey on the experimental fields, two-factor coincidence plots were carried out in the form of a three-repeated potting experiment according to the trial pattern during the summer growth seasons of 2013 and 2014. Effects of different nitrogen (0, 50, 100, 150, 200 N/ha) and potassium (0, 50, 100, 150 kg K2O/ha) levels of on ethanol yield of sweet sorghum were investigated, in the experiment. N was applied in two equal doses in the experiment. K2O was mixed with soil and supplied as a single application. Some parameters were tested in the experiments such as stalk and juice yield, sugar content and theoretical ethanol yield. Results indicated that the effects of N and K treatments on all characteristics tested were significant. Application of the higher rates of N and K increased the ethanol yields compared to the control treatment. Based on these results the combination of N150-K100 were proved to be the best fertilizer level for ethanol yields of sweet sorghum grown under Mediterranean ecological conditions of Izmir.
