Published: July 2023

ABSTRACT

Aim:

Evaluation of the efficacy of different obturating techniques and assessment of the presence of voids in different regions of the canal.

Materials and Methods:

Sixty permanent single-rooted teeth with complete, mature root apices without any anatomic variation having straight patent root canals were included in the present study. Access cavity preparation followed by biomechanical preparation was done. Samples were divided into three groups—Group A: Single cone obturation, Group B: GuttaFlow 2, and Group C: GuttaCore, and obturation was carried out. The samples after obturation were stored at 370°C and 100% humidity in an incubator for 7 days to give adequate time for obturating materials to set. Cone beam computed tomography was performed with i-cat Cb 500 machine. The voids were checked on the root canal wall. The statistical analysis was done and the data after the statistical analysis was presented.

Result:

GuttaCore obturators presented a lesser volume of voids followed by GuttaFlow 2 than the single cone techniques.

Conclusion:

All the obturation techniques presented an inadequacy of obturation when the pre- and post-obturated volume of the root canal space was calculated. However, no statistically significant obturated volume differences were found between single cone and GuttaFlow 2 or between GuttaFlow 2 and GuttaCore system.

ABSTRACT

Plaque control, pain control, and modulation of inflammatory mediators to accelerate or stabilize tooth movements are hot issues in orthodontics. The recent advent of phytochemicals as biological mediators has opened new vistas in the aforementioned areas of orthodontics. Adhatoda vasica has caught the attention of investigators due to multiple properties related to orthodontics. This study addresses the potential areas of use of A. vasica in orthodontics, which provide ideas for further investigations. A. vasica possesses antibacterial activity, antifungal activity, anti-oxidant effect, anti-inflammatory activity, analgesic effect, osteogenic, and osteoclastic activities. A. vasica has huge potential in orthodontics, whereas all these vistas need careful and methodical testing before use in clinical orthodontics. In the future, investigators can focus on these aspects of the use of A. vasica to develop products.

Published: July 2023

ABSTRACT

Introduction:

Transgenders (TGs) are one of the vulnerable groups in our society. Trans people experience substantial health disparities and barriers to appropriate health care services that keep them from achieving the highest possible health status.

Methodology:

The study was conducted over the course of 12 months at the Transgender Shelter Home. Focus group discussion (FGD) took place with 6–12 participants and the researcher acted as moderator. The questions were asked under four domains; sociodemographic variables, behavioral variables, medical and health status variables, and access and utilization of dental services barrier variables. Transcripts were coded and data analysis was concurrent with data collection to allow to know new insights. The data analysis was done by MAXQDA software 2022.0.0. It is being developed and distributed by VERBI Software based in Berlin, Germany.

Results:

The barriers and facilitators explored were categorized at three levels: (1) the personal level, relating to those barriers and facilitators that the individual faced for their oral health care, and the perspectives regarding the delivery of care; (2) the inter-personal level; and (3) the system level, for identifying the wider elements and their influence.

Discussion:

Social stigma and marginalization have been linked to adverse health effects, including personal attributes, structural and environmental factors, and personal perceptions of stigmatization.

Conclusion:

It is evident that lesbian, gay, bisexual, transgender, and queer (LGBTQ) communities have specific but varied health care needs, and the greatest way to treat these necessities is via exposure to professional, health care coverage.

Authors: Vincent Kiran , Aslam Sachin , Abida Roshni , Thomas Tom , Cherian Mathew Pynummoottil , Soman Sooraj
Published: July 2023

ABSTRACT

Aim:

This is an era of minimally invasive and least traumatic surgical interventions being focused on. The traditional scalpel frenectomy technique offers an increase in post-operative sequelae. To unravel this scenario a comparative evaluation is carried out to find out the clinical outcomes and quality of life after maxillary labial frenectomy using a conventional scalpel and diode laser frenectomy of 980 nm.

Materials and Methods:

Thirty-six subjects age ranging between 18 and 45 years reported to the Department of Oral and Maxillofacial Surgery, MES Dental College, Perinthalmanna with an aberrant frenal attachment of maxillary labial frenum were randomly assigned into two groups. Group A underwent the conventional scalpel technique and group B for the diode laser-assisted (980 nm) frenectomy technique. The post-operative parameters of ooze from the surgical site, pain, wound healing, and discomfort or acceptance of the procedure were assessed on day 1, day 7, and day 14, respectively.

Results:

The diode laser group exhibited statistically significant clinical and healing outcomes. Less pain, minimal or absent ooze, increased healing, and better acceptance of the procedure with diode laser at 1, 7, and 14 days recall visit.

Conclusion:

Surgical interventions involving needle puncture and the associated post-operative sequelae are the most dreaded experiences that make patients indifferent toward surgical treatments. Thus in terms of better clinical outcomes and improved quality of life diode laser frenectomy is an excellent alternative wherein a needleless anesthetic success followed by minimal surgical intervention and less post-operative sequelae with fast recovery is possible.

Authors: Sinha Priti R. , Mallick Nitin , Sahu Ramjee L.
Published: July 2023

ABSTRACT

Background and Objectives:

It is clear that COVID-19 can have a wide range of effects on the body, and the musculoskeletal system is no exception. Studies are ongoing to better understand how the virus may impact the hip bone and joint tissue. However, it is known that COVID-19 can cause inflammation and damage to various parts of the body, including the bones and joints, which could lead to pain, stiffness, and other symptoms.

Materials and Methods:

A retrospective analysis is done with ten patients admitted to the hospital due to COVID-19 and later complained of hip pain. Magnetic resonance imaging (MRI) was performed on the patients, and it was found that they had degenerative changes characterized by avascular necrosis (AVN) of the head of the femur. One of the patients had a history of previous surgery on the femur with a plate and screws and was doing well but developed AVN after contracting COVID-19.

Results:

Observation among these groups shows a strong association between the history of COVID-19, high levels of IgG antibodies, the presence of joint abnormalities, and moderately severe symptoms. There is no evidence of identifying autoimmune, degenerative, or AVN diseases. This set of patients responded positively to supportive therapy and anti-inflammatory drugs used in empirical treatment, which subsided joint pain and acute inflammatory symptoms.

Conclusions:

It has been determined that there are significant musculoskeletal complications in COVID-19 patients, including AVN, which may be caused by the high use of steroids and microembolism leading to bone necrosis. Therefore, further studies and long-term follow-up are recommended.

Published: July 2023

ABSTRACT

Background:

Oral potentially malignant disorders (OPMDs) are chronic lesions or conditions characterized by a potential for malignant transformation. One of the hallmarks of cancer is aerobic glycolysis which confers immortality to cancer cells, correlates with the belligerent behavior of various malignancies, and shows an increase in the expression of lactate dehydrogenase (LDH). The present study was conducted to measure and compare serum and salivary LDH levels in patients with habit, OPMDs and oral squamous cell carcinoma (OSCC) patients, and to evaluate if LDH levels can be used as a biomarker in the progression into potentially malignant disorders (PMDs), the prognosis of OSCC, and to assess if saliva is a better biomarker.

Materials and Methods:

Thirty patients of both genders were divided into three groups. Group I had patients with habits, group II had OPMDs, and group III had OSCC with 10 subjects from each group. Saliva and serum of patients were collected according to the standard protocol and measured for LDH using spectrophotometry of 340 nm.

Results:

Group I had patients with habits, group II had OPMDs, and group III had OSCC. Group I had 6 males and 4 females, group II had 8 males and 2 females, and group III had 7 males and 3 females. The mean serum LDH level in group I was 265.50, in group II was 194.10, and in group III was 224.22. The difference was non-significant (P > 0.05). The mean salivary LDH level in group I was 345.68, in group II was 532.72, and in group III was 1.105. The difference was significant (P < 0.05).

Conclusion:

Salivary LDH is a non-invasive, cost-effective technique, which can be used as an effective modality for the diagnosis and prognosis of oral cancer as well as for monitoring tobacco users and OPMDs.

Authors: Movalled Kobra , Zavvar Morteza , Zafardoust Hooman , Salehi-Pourmehr Hanieh , Arlandis Salvador , Ghavidel-Sardsahra Amirhossein , Hajebrahimi Sakineh
Published: July 2023

Purpose:

This study aimed to review the functional urology guidelines, relate the level of evidence (LOE) of their recommendations and highlight the discrepancies between the LOE and grade of recommendation.

Materials and Methods:

The electronic search was conducted in May 2019 and updated in February 2021. Three researchers separately reviewed the extracted guidelines based on the Appraisal of Guidelines for Research and Evaluation II instrument. We extracted recommendations from each guideline and ranked them into three Grades of A, B, and C; and their evidence into four levels of I to IV.

Results:

Among the published functional urology guidelines, 18 guidelines were published between 2014 and 2020. Overall, 592 recommendations were abstracted. Of these, 121 recommendations were related to evaluation or diagnosis, and the others (n = 471) on the disease management. These recommendations were in the field of urinary incontinence (UI) (n = 216), overactive bladder (OAB) (n = 172), lower urinary tract symptoms (LUTS) (n = 126), and neurogenic bladder (NGB) (n = 78). Subgroup analysis showed that most of the recommendations in relation to UI were Grade A (n = 111; 51.4%), and one-third were Grade C (n = 83; 38.4%). The remaining 22 recommendations were Grade B (10.2%). In OAB, most of the recommendations were Grade B (n = 67, 39.0%), 55 of them were Grade A (32.0%) and the rest were Grade C (n = 50, 29.1%). Among UI guidelines, 51 (45.9%) Grade A recommendations were supported by LOE I evidence, and 39 (47.0%) Grade C recommendations were supported by LOE IV evidence. Across OAB guidelines, 43 (78.2%) Grade A recommendations were supported by LOE I evidence, and 20 (40.0%) Grade C recommendations were supported by LOE IV evidence. Across LUTS guidelines, 34 (61.8%) Grade A recommendations were supported by LOE I evidence, and 14 (23.3%) Grade C recommendations were supported by LOE IV evidence. Among NGB guidelines, 21 Grade A recommendations were supported by LOE I evidence, and 9 Grade C recommendations were supported by LOE IV evidence.

Conclusion:

Most of the recommendations in the field of functional urology are not based on the systematic review and meta-analysis of randomized controlled trials (RCTs) and high quality RCTs; which indicates that more attention is still needed in making decisions based on the certainty and grade of recommendations.

This articlestudies the problem of classifying imbalanced data, introduces dynamic sampling for deep neural networks,investigates the imbalanced multiclass problem, and proposes a dynamic sampling method for deep learning.In our proposed method, all samples are fed to the current deep neural network for each training iteration,and the accuracy, precision, and mean error of the deep neural network are estimated. The proposed methoddynamically selects informative data for training the deep neural network. Comprehensive experiments wereconducted to evaluate and understand its strengths and weaknesses. The results of 13 imbalanced multiclassdatasets show that the proposed method outperforms other methods, such as initial sampling techniques,active learning, cost-sensitive learning, and reinforcement learning.
A Framework for Utilizing Permutational Multiple Analysis of Variance as a Precursor for Nonparametric Statistical Learning with Cyber Network Data
Authors: Woolman Thomas , Pickard John
Published: July 2023

INTRODUCTION: Although scientific hypothesis testing methodologies are well established, their application to falsifiable hypothesis testing for assessing causal relationships potentially identified by machine learning and artificial intelligence models is rare due to the primarily nonparametric statistical nature of these systems.OBJECTIVES: The primary objective of this study is to demonstrate the potential for applying nonparametric statistical tests to a mixed qualitative and quantitative cyber network dataset as a method to pre-assess the feasibility of applying forms of statistical hypothesis testing before a machine learning algorithm models the data.METHODS: A mixture of permuted analysis of variance models augmented by the use of transformed non-Euclidean multivariate distances between curated dependent variable classes produced this research data. Quasi-experimental data   from an enclosed laboratory environment utilizing a monitored, locally unrestricted network that introduced known Internet of Things (IoT) malware software supplied network flow events.RESULTS: A PERMANOVA model was executed against 62,000 records of the network flow observations, using Euclidean distance measurements with variable-dependent relationship ordering, using terms added sequentially (first to last) in the order encountered in the raw network flow dataset, using 200 permutations. This precursor test resulted in a p-value for the PERMANOVA model that incorporated terms added sequentially of 0.02985, providing an F value of 0.00017 with which to determine the ratio of explained to unexplained variance. Utilizing an analysis of the F values for all of the residuals, we show 29,998 degrees of freedom with a residual F model score of 0.99983, indicating that there is a strong proportion of explained to unexplained variance across all of the independent variables contained in the model. The model is thus statistically significant with a p-value below the alpha test statistic of 0.05.CONCLUSION: This research has demonstrated that it is possible to apply tests of falsifiability that incorporate reproducible methods into the quasi-experiment design and apply this to the field of machine learning. Applied to AI/ML (artificial intelligence/machine learning) models, this pre-assessment methodology supports the appropriateness of cyber network flow datasets in which a final test of statistical significance would be required. The authors believe that this represents a substantially useful precursor assessment stage for the suitability and reliability of the utilization of any nonparametric statistical learning algorithms applied to cyber network data predictive analytics.

Authors: Sun Wei , Zheng Zuo-Huan
Published: July 2023

We first introduce the concept of weak random periodic solutions of random dynamical systems. Then, we discuss the existence of such periodic solutions. Further, we introduce the definition of weak random periodic measures and study their relationship with weak random periodic solutions. In particular, we establish the existence of invariant measures of random dynamical systems by virtue of their weak random periodic solutions. We use concrete examples to illustrate the weak random periodic phenomena of dynamical systems induced by random and stochastic differential equations.
A basis- and integral-free representation of time-dependent perturbation theory via the Omega matrix calculus
Authors: Francisco Neto Antônio
Published: July 2023

We obtain a basis- and integral-free representation of the

n

-term in time-dependent perturbation theory of the quantum time-evolution operator. The main technical tool to construct the aforementioned representation comprises the Omega matrix calculus; that is, an extension of MacMahon’s partition analysis to the realm of matrix calculus. In particular, we show that if we specialize our formulation to the time-independent and finite-dimensional case, we recover Putzer (1966) original formulation to compute the matrix exponential avoiding the Jordan canonical form. Furthermore, if we use an explicit basis for the time-independent part of the generator of evolution, then our work implies a representation of the perturbation expansion similar to an approach discussed in the recent work of Kalev and Hen (2021) using divided differences. Finally, we obtain closed form expressions which generalize and unify all the perturbation calculations considered in Kalev and Hen (2021) and advance some considerations regarding degeneracy associated with the unperturbed Hamiltonian in the context of adiabatic switching.

Authors: Periyannan L. , Saravanan P. , Lavanyaa P. , Prabhu B. , Silambarasan R.
Published: July 2023

In contrast to standard fuel, biodiesel continues to burn cleaner. However, repeated studies have revealed that when compared to conventional diesel fuel, biodiesel generates more NOx formation. In this research, methyl ester of Annona (AOME) oil is applied to produce biodiesel by a transesterification process. The antioxidant is administered in varying quantities in w/w basis ranging from 0.010 to 0.040%. Without altering the engine, the findings suggest that the antioxidant additive mixture AOME+P200 is effective in lowering NOx and HC emissions of AOME fuelled engines.
Autonomous Control Method for Object Grasping of Logistics Sorting Manipulator Considering Changes in Lighting Environment
Authors: Liu Ying
Published: July 2023

The autonomous grasping operation is the key to the intelligent logistics sorting manipulators. Since the current logistics sorting manipulators mostly use visual sensors to identify objects, they are extremely vulnerable to the changes in the lighting environment. Therefore, the research considers the influence of complex lighting environment on the autonomous grasping of logistics sorting manipulators. Furthermore, it verifies the effectiveness of SAC-AE-ICM algorithm through simulations and experiments. The experimental results show that SAC-AE-ICM algorithm can quickly achieve convergence in many experiments and can obtain global optimization. In the process of automatic capture, the success rate of SAC-AE-ICM algorithm can reach 90%, which is 25% higher than that of the method without ICM and has better convergence. The success rate was as high as 77% for unknown or irregular targets. In practical experiments, SAC-AE-ICM can effectively capture under good lighting conditions. However, under low light conditions, the probability of capturing unknown targets is about 72.5%. Overall, the success rates for single-object and multi-object capture are 88% and 85%, respectively.

Published: July 2023

The biodiesel can be extracted from different sources and then it is blend with engine fuels to counter factors like fuel scarcity, pollution, cost and increasing of consumers. The use of algal oil diesel-biodiesel blend is one of the methods to reduce the emissions and in increasing performance of jet engine. To emphasize on the reduction of NOx in the combustion chamber of the jet engine. Combustion chamber is the main part of the jet engine where many important chemical reactions take place and generates heat. In this paper, the main focus is on the percentage of NOx in the output and how we can reduce that by changing some parameters into input. The challenges in fuel high performance combustion engines haven’t had any major changes over the years. However, more sophisticated analysis process has been deployed to overcome these challenges. The biofuels i.e., algal oil diesel-biodiesel is taken first to blend, then standard boundary conditions were applied and then observed the results carefully. By looking at the results then decided to make some changes in the diesel i.e., the bio diesel (B10, B15 and B20) where it found drastic changes in NOx emission and got some more positive changes.

Effect of Wire Electric Discharge Machining Parameters on Material Removal Rate in Machining of Titanium Grade 7 Alloy
Authors: Basavaraju H.R. , Suresh R. , Manjunatha S.S.
Published: July 2023

Titanium alloys are widely used in various fields, including the medical field, the automotive and manufacturing sectors. Traditional machining processes are only useful for a limited number of tasks due to the detrimental effects they have on the strength and stiffness of the machined alloys. However, one of the most favoured post-processing equipment used to obtain a high-quality surface is the wire electrical discharge machining (WEDM) technology. The most crucial aspects of WEDM are the rates of the electrical current and voltage, in addition to the pulse-on and pulse-off durations. As a form of wire, WEDM makes use of brass wire that has been zinc-coated. The WEDM method is utilised in the machining of titanium alloy of grade 7 for this project. The surface of titanium grade 7 that had been processed using WEDM was analysed with a scanning electron microscope. The pictures revealed that the material exhibits homogenous solidification and a columnar grain structure along the build direction. As the pulse-on time gets longer, the Material Removal Rate (MRR) also gets higher. When the pulse-on time is set to 60 µs, the greatest MRR that can be achieved is 7.357 mm3/min. As the pulse-off duration gets longer, the MRR is getting lower. At a pulse-off time of 20 µs, the minimal MRR is reached, and it is equivalent to 5.935 mm3/min. At a peak current 6A, the highest MRR is measured is equivalent to 7.795 mm3/min.

Authors: Mohammed A.S. , Babu N.R. , Sivaprakasam P. , Udayaprakash J.
Published: July 2023

This paper elaborates on the modal analysis and comparison of truck chassis frames made of composite materials (Carbon/Epoxy and E-glass/epoxy) and mild steel using the finite element method (FEM). All the specifications of the vehicle were taken from Bishoftu Automotive Industry, Ethiopia. Weight reduction has been achieved by 79.48% and 66.67% for carbon/epoxy and E-glass/epoxy respectively. The modal analysis shows that the first six natural frequencies of carbon/epoxy, E-glass/epoxy and mild steel are in the ranges from 56.8Hz to 134.8Hz, 27.22Hz to 64.59Hz and 31.97Hz to 75.88Hz respectively. The first two natural frequencies for carbon/epoxy and all-natural frequencies for E-glass epoxy and mild steel are in the engine excitation range. The main disturbance is due to the road excitation which ranges from 0 to 100 Hz, which is even greater than the engine excitation. Carbon/epoxy is the best candidate that some of its natural frequencies are above the engine and road excitations as compared to steel and E-glass epoxy chassis frames.
Exploring Young Women’s Perceptions of Their Food Skills
Authors:   Brescia University College at Western University, 1285 Western Road, London, Ontario, N6G 1H2, Canada, Matthews June
Published: July 2023

Many young adults mistakenly perceive that they have good food safety knowledge and are unlikely to experience foodborne illness. Young women’s food skills are of partic- ular importance because women are responsible for most food-related tasks in the home and many children learn food skills from their mothers. This descriptive qualitative study explored young women’s perceptions of food skills in three domains: food selection and planning, food prepara- tion, and food safety and storage. Through individual inter- views, 30 young women aged 17 to 30 years answered the following three key research questions: (i) What do food skills mean to you? (ii) How did you learn them? and (iii) In what areas are you most and least confident? Few participants mentioned food safety in their top-of- mind definition of food skills. More than half were least confident in the domain of food safety and storage. Fear prompted avoidance of cooking meat – even by those who were not vegan or vegetarian. Food skill interventions or curricula should emphasize food safety and storage so that young adults can reap the dietary and financial benefits of preparing all types of food. Consistent with others’ recom- mendations, the two most important food safety topics for educating young adults should be (i) cross-contamination and sanitation procedures and (ii) safe times and tempera- tures for cooking or storing food.
Polyaniline-derived nitrogen-doped carbon/MoS2 nanocomposites as cathode for efficient hybrid capacitive deionization
Authors: Liu Zhuannian , Wei Benlong , Wang Liping
Published: July 2023

Molybdenum disulfide (MoS2) has become an attractive faradic material for capacitive deionization (CDI) process, but it still suffers from several drawbacks, such as low electrical conductivity, inferior hydrophilicity and easy restacking. Hence, we integrated MoS2 with high nitrogen content carbonized polyaniline (MoS2/CP) as intercalation cathode for CDI. The disordered entanglement between MoS2 and CP nanosheets enlarged interlayer spacing, improved pore structure and surface area which can provide multiple charge transfer routes and endow more embedding sites to storage Na+. The Mo-N-C bonds improve the electrical conductivity and wettability to facilitate ions diffusion process as well as ensure the cyclic stability of composites electrode. Moreover, the charge transfer between Na+ and N-containing functional groups is beneficial to forming pseudo-capacitance. Accordingly, the MoS2/CP electrode possess a large specific capacitance of 99.1 F g-1 at 5 mV s-1, which is 36% higher than MoS2. The hybrid cell AC//MC-2 delivers a remarkable desalination capacity (29.14 mg g-1), a rapid desalination rate (2.9 mg g-1 min-1) and favorable cyclic durability at 1.2 V in 500 mg L-1 NaCl solution. The superior desalination performance of MoS2/CP electrode was evaluated based on a capacitance-controlled contribution of 85.8% and a diffusion-controlled contribution of 14.2%.

Published: July 2023

The F&B market in Indonesia, including coffee shops such as Brush and Palette, has experienced significant growth due to increased consumption in Indonesia. With increasing consumption in the F&B industry, there is a target market for coffee shops. From interviews with the owner of Brush and Palette, it was revealed that sales were stagnant and below target which raised concerns about revenue stability and sustainable growth. By focusing marketing efforts on promoting and eliciting purchase intent, Brush and Palette can strategize to increase sales and align with customer preferences.

This study examines the relationship between family education expenditure and education equalization, focusing on the role of social policy in promoting educational opportunities for all. The research finds a positive correlation between education equalization and family education expenditure, indicating that increased investment in education by families contributes to greater equity in educational outcomes. Through a survey of parents of students, it is observed that there is a positive relationship between education equalization and family education expenditure. This suggests that parents who prioritize education and allocate more resources towards it tend to support policies and initiatives aimed at reducing educational disparities and promoting equal access to quality education for all students.

The Conceptual Access-NeTwORk (CANTOR) Thesis: Theorizing the Development or Success of New Internet-Based Products, Services, or Technologies
Authors: Carroll La Shun L.
Published: July 2023

For any new internet-based product, service, or technology to succeed, it must satisfy the criterion of providing access to or creating a network of possible users, products, and services. This is the Conceptual Access-Network (CANTOR) Thesis proposed. In addition to the main issues of success and how and why internet technology evolves, the principle can also meet the objective of explaining what underlies a range of traditional and nontraditional technologies beyond the internet. Through qualitative exploration, the tenets of the access-network thesis are applied to natural and synthetic forms of endocrine substances including insulin and highways. A discussion of technologically generated knowledge is included, as well as how phenomenotechnique can be used to establish a communication path between technology and what it produces. Dr. Stanley Milgram's intimate stranger phenomenon which was first explored in 1967, before the internet existed, will ultimately be distorted by the future of internet-based technologies.  As previously discovered or established concepts are combined or permuted, the future will display numerous manifestations, combinations, and permutations. We conclude that successful internet-based products, services, or technologies simply would not work without an access network. From this article, we have gained a better understanding of the current development stage of internet-based products and technology, thereby enabling society to better anticipate the future of internet-based products and technology, highlight significant ethical considerations, and avoid unwanted outcomes.

Published: July 2023

The review discusses students’ challenges as they move between educational levels and the labor market, mainly due to the lack of effective, efficient, and timely career guidance. The review suggests that using ontologies can improve career guidance delivery by providing a structured approach to representing and organizing career-related data. The study conducted a systematic literature review and found that ontologies have not been extensively applied in the career guidance domain. The review highlights the unique advantages of using ontologies for career guidance (CG), such as formal representation, interoperability, and knowledge representation and reasoning. The review also points out the loopholes in the few studies that attempted to use ontologies in CG. A systematic literature review was carried out to assess the extent to which ontologies have been applied in CG. Four reviewers performed a systematic search in IEEE, Scopus, Web of Science, and google scholar independently using agreed-upon criteria. To eliminate the bias of leaving out important studies, abstracts from selected conferences were carefully screened and reference scanning of the search results was performed. Out of 307 studies, 11 were found to match the search parameters and were included in the study.

This study compared the effects of the channels mediating customer emotional responses and the channels mediating satisfaction in relation to the influence of marketing stimuli on word-of-mouth intentions in Korean fine dining restaurants. To this end, a total of 320 people were surveyed, and frequency analysis, reliability analysis, exploratory factor analysis, correlation analysis, and regression analysis (SPSS PROCESS macro model 4) were conducted using SPSS 18.0. The results of this study are as follows. First, customer emotional responses are partially mediated in the relationship between the influences of sensory marketing elements (sight, touch, hearing, and smell) on word-of-mouth intention. However, customer emotional response does not mediate in the relationship between taste factors and word of mouth intention. Second, satisfaction is partially mediated in the relationship between the effects of sensory marketing on word-of-mouth intention.
Trendfordulók Montenegróban
Authors: Németh Ferenc
Published: July 2023

Az elmúlt három év politikai átalakulása az idén megtartott elnök- és parlamenti választásokkal lezárulni látszik. A Szocialisták Demokratikus Pártjának ellenzékbe kerülése (2020), valamint Milo Đukanović elnökválasztási veresége (2023) megerősíti a politikai pluralizmust, de nem jelent egyet a stabilitással. Az újonnan alakult és a politikai szcéna megkerülhetetlen szereplőjévé vált Európa most párt és a pártot vezető politikusduó népszerűségének fennmaradása a kezdeti sikerek ellenére nem garantált, Montenegró legégetőbb kihívásai pedig nem politikai, hanem gazdasági természetűek lesznek.
