ABSTRACT Salinity is considered an obstacle to the production system that limits the growth and yield of crops around the world. Therefore, it is essential to develop strategies to minimize the effects of salinity and increase yield, especially in the semi-arid region of the Northeast, which has limited water resources of good quality for irrigation. The objective was to evaluate the effects of applying paclobutrazol on zucchini crop under salt stress. The experiment was conducted in a greenhouse, in a randomized block experimental design, in a 2 × 5 factorial scheme, with two salinity levels of irrigation water (0.6 and 4.0 dS m-1) and five concentrations of paclobutrazol - PBZ (0; 2; 4; 6 and 8 g L-1), and with four repetitions. Application of 8 mg L-1 PBZ increases stem diameter in zucchini under irrigation of 4.0 dS m-1. Chlorophyll b and total chlorophyll contents increase with PBZ concentration of 4 mg L-1 and irrigation of 0.6 dS m-1. PBZ concentration of 4 mg L-1 increases the relative water content while reducing electrolyte leakage in zucchini under salinities of 4.0 and 0.6 dS m-1 respectively. Root, stem and leaf dry mass of zucchini increases when plants are irrigated with water of 0.6 dS m-1 and subjected to PBZ concentration of 8 mg L-1. PBZ concentrations do not attenuate the effects of salinity on leaf area, crown volume and diameter, vegetative vigor index, chlorophyll a and carotenoids.
Response of susceptible carnation cultivars during thiamine application as inducer of resistance to vascular wilting caused by Fusarium oxysporum f. sp. dianthi

Published: March 2024

Abstract Colombia is one of the main producers of carnations worldwide. However, its production has been affected by vascular wilting caused by the pathogen Fusarium oxysporum f. sp. dianthi (Fod). In previous studies, thiamine has been proposed as a potential resistance inducer for this disease, under greenhouse growth conditions. However, the specific conditions for its application must be studied when applying it under commercial conditions. In this sense, this study aimed to evaluate the effect of the thiamine foliar spray in different concentrations among some susceptible carnation cultivars in response to Fod-inoculation. For this, two in-vivo trials were carried out, using foliar spraying of thiamine as a treatment before inoculation with the pathogen Fod, then measurements of incidence, severity, and the content of phenolic and flavonoid compounds were made. It was found that thiamine application, in the concentrations evaluated, shows a statistically similar decrease in the disease incidence and severity. These results were verified using multivariate statistical analysis. In addition, it was found that the application of thiamine 1 mmol L-1 presents a positive response in reducing the effects of the disease in three susceptible cultivars. The results suggest that thiamine has the potential to be applied as a technique in the integrated management of disease in the productive sector.

Abstract The use of bacteria and seaweed extracts as biostimulants to enhance plant growth holds promise for sustainable turfgrass management. This study aimed to investigate the effects of soil application of Azospirillum brasilense (bacterium) and Ascophyllum nodosum (seaweed) extract on the initial growth of DiscoveryTM bermudagrass. The study was conducted using a completely randomized design with plots measuring 0.25 m², each with a 0.5 m border. Two separate experiments were conducted, each involving four doses of biostimulants and five repetitions. The biostimulant treatments consisted of 0, 2, 4, and 6 mL L¹ A. brasilense inoculant and 0, 5, 10, and 15 mL L¹ A. nodosum seaweed extract. These treatments were uniformly applied to the soil at a rate of 100 mL m², with applications at 0, 30, and 60 days after the start of the experiment. After 90 days, the parameters green color index, green cover rate, turfgrass height, and vegetation index (normalized difference), were evaluated. The results indicated that both biostimulants significantly promoted the initial growth of DiscoveryTM bermudagrass. As the doses of the biostimulants increased, there was a corresponding increase in biomass and improved development of the turfgrass. The most pronounced responses were observed with a dose of 6 mL L¹ of the bacteria inoculant and 15 mL L¹ of the seaweed extract. These biostimulants fostered better turf coverage, making it challenging for weeds to establish, and potentially accelerating the production of sod grass.

Published: March 2024

ABSTRACT Traumatic atlanto-occipital dislocation is a rare, severe, and usually fatal injury. In this paper, we report the case of a 28-year-old patient with multiple trauma, who suffered an atlanto-occipital dislocation (AOD) associated with rotatory dislocation at C1-C2, condyle fracture and traumatic brain injury resulting from a car accident, with a cardiopulmonary arrest at the accident site. The patient had motor and sensory deficits, suffering other complications of clinical severity during hospitalization. After two years of surgical treatment follow-up, the patient had a complete recovery of neuromotor and sensory functions. This case demonstrates that neurological recovery with minimal sequelae is possible, even after an unfavorable prognosis resulting from a severe injury with a high risk of death as this kind of trauma. It is essential for health professionals to have the ability to identify and treat AOD, ensuring improved clinical outcomes, reducing mortality and morbidity, and providing a better life to affected patients.

Determination of coarse aggregate content of concrete specimens by wave propagation and Artificial Neural Network
Authors: Santos Danilo Pereira dos , Haach Vladimir Guilherme
Published: March 2024

Abstract Nondestructive tests that assess the constitution or degradation of structures are of great interest in Civil Engineering. Among the non-destructive testing techniques, the Ultrasonic Pulse Velocity (UPV) test stands out; however, although its use is widespread, there are still no applications that employ this method to determine the constitution of concrete in situ. Therefore, this article addresses the identification of the coarse aggregate content in concrete specimens by an Artificial Neural Network (ANN) trained with a database of numerical tests that simulated UPV. In this paper, the coarse aggregate content will be described as a percentage of the total area of a two-dimensional concrete model. Three artificial neural network architectures were evaluated. The first two, trained with 13 or 22 paths, solved a classification problem for five aggregate contents, and the third, trained with 22 paths, solved a regression problem. Its performance was compared with those of other regression solutions, namely XGB Regressor, Random Forest, and OLS (Ordinary Least Squares), and showed superior, with -2.55% to +2.17% average deviations. Thus, this paper demonstrated that the use of ANN in combination with UPV test has the potential to identify the coarse aggregate content in concretes. The positive results suggest that this approach is promising and highlights the need for further experimental validation in future research.

Published: March 2024

Abstract— The new species Microlicia arenaria, M. dentisepala, and M. membranacea are described from the Diamantina Plateau, Minas Gerais state, Brazil. Microlicia arenaria is a cespitose subshrub with xylopodium, fastigiate
branches, forming clumps, sessile leaves, linear lamina, and hypanthium and sepals covered with golden spherical glands. In addition, it has dimorphic and bicolored stamens with tetrasporangiate anthers. Microlicia dentisepala has a subshrub or shrub habit, is erect and much branched,
and its leaves are small, varnished in appearance, with both surfaces covered with spherical glands. The sepals are triangular to narrowly lanceolate and shorter than the length of the hypanthium, with a tooth aspect. Microlicia membranacea is a subshrub with petiolate leaves, lamina
of membranous consistency and suprabasal venation, with prominent secondary veins. The branch, leaf, hypanthium, and sepals are covered with glandular trichomes, and the cylindrical hypanthium is slightly contracted at the apex. Microlicia arenaria and M. dentisepala exhibit
some anatomical features common to Microlicia, such as amphistomatic leaves, short-stalked glandular trichomes in depressions on the leaf surface, compact mesophyll, phenolic compounds in the subepidermal layer, idioblasts with druses in the mesophyll, and collateral vascular bundles.
Microlicia membranacea stands out by its hypostomatic leaves and a thin mesophyll formed by only three to four cell layers, conditions possibly related to a shaded environment. Following the criteria of the Red List of the International Union for Conservation of Nature (IUCN), we preliminarily
assess the conservation status of the species Microlicia arenaria as Endangered (EN), Microlicia dentisepala as Critically Endangered (CR), and Microlicia membranacea as Data Deficient (DD). We provide descriptions of the new species, along with field images, detailed
illustrations, and comparisons with related species. Data on geographic distribution and habitat are also presented.
Two New Species of Aphyllon from Northeastern Mexico

Published: March 2024

Abstract— Plants originally identified as Aphyllon ludovicianum that occur near Monterrey, Nuevo Leon, and Cuatro Ciénegas Bolson, Coahuila, Mexico, were found to not align with the protologue of that species, the close relative A. multiflorum,
or any other species of Aphyllon. Following a detailed study of floral morphology, geographic range, host species, and phylogenetic position using dry herbarium specimens, field study, and georeferenced color photographs, we propose the new binomials Aphyllon spectabile
for the plants from Nuevo Leon and Aphyllon gypsophilum for the plants from Coahuila, Mexico. These additions increase the taxonomic diversity of Aphyllon to 27 species plus ten additional subspecies. Gymnosperma glutinosum and two species of Xanthisma were
reported for the first time as a host species for the genus Aphyllon. We also provide an updated key to Aphyllon in Mexico.

Published: March 2024

Space payloads are required to be compact, to withstand harsh climatic conditions, and perform well over the duration of a mission. Advanced lightweight materials with low density, high strength, and high specific stiffness, such as carbon fiber reinforce polymers (CFRP), controlled expansion alloy (CE7), and kevlar composites are better suited for space hardware. Despite of having superior mechanical qualities, CFRP composites have limited range of applications due to their worse electrical and
thermal conductivities. By adding nano-fillers to improve conductivity, CFRP can be used extensively.
The most often employed conductive nano-fillers in CFRP composites are graphene and carbon nanotubes
(CNTs). By creating CFRP composites with superior conductivities, the use of CFRP composites can be extended over large applications for space missions. Materials such as aluminum, kovar, invar, and other composites (non-conductive in nature) may be replaced by CFRP-CNT composites. It can be used for fabricating broad variety of satellite hard wares, including satellite panels, reflectors, feed horns, wave guides, carrier plates, electronic package boxes, and covers. Based on tests with different configurations, it was discovered that 0.5% SWCNT offered better mechanical and electrical properties.
CNT-CFRP composites are used in the development of carrier plates and reflectors. This article primarily focuses on development of qualification test strategy and how it differs from traditional systems test plan. Results from test coupons and the product level tests were compared and analyzed. The results are acceptable and found better in comparison to their conventional counterparts.

Authors: Ma'ruf Anwar , Purnawanto Agus Mulyadi , Hayat Latiful , Astuti Novi
Published: March 2024

Microbial fuel cell is a new technology that utilizes bacteria as biochemicals to convert energy stored
in organic/inorganic compounds, which is easily degraded into electrical energy. Apart from being able
to produce electrical energy, the implementation of this technology can help solve the problem of processing
wastewater resulting from cassava fermentation. The specific aim of the research is to examine the effect of cassava fermentation wastewater concentration and the effect of urea addition on the productivity of electricity produced and the reduction in the quality of cassava fermentation wastewater.
From the research results, it can be concluded that the higher the cassava fermentation wastewater concentration, the smaller the electrical energy produced. The optimum initial cassava fermentation wastewater concentration is 20% v/v, with an average volumetric power density produced of 58.56 W/m3. The higher the concentration of added urea, the smaller the electrical energy produced. The optimum concentration of urea addition is 0.16-0.33 g/L. There is a linear relationship between the electricity produced and the decrease in total suspended solid (TSS) and total dissolved solid (TDS).
The higher the electricity produced, indicating high bacterial activity, will cause a decrease in TSS and TDS.

Published: March 2024

Brazil-grown outdoor-cultivated Agaricus brasiliensis KA21 fruiting body (KA21) significantly increases the production of serum anti-beta-glucan antibody. Therefore, KA21 ingestion may be useful for the prevention and alleviation of fungal infections. This study aimed to determine the effects of KA21 in fungal infections in animals. KA21 was administered to nine dogs infected with Malassezia. Notably, the anti-beta-glucan antibody titer remained unchanged or tended to decrease in the oral steroid arm, whereas in the non-steroid arm, antibody titer increased in almost all animals after KA21 ingestion. Dogs showing improved clinical symptoms exhibited increased anti-beta-glucan antibody titers. The results of this study suggest that KA21 ingestion may alleviate the symptoms of Malassezia and other fungal infections and that continuous ingestion may help prolong recurrence-free intervals. Additionally, the ingestion of KA21 during oral steroid dosage reduction or discontinuation may enable smoother steroid withdrawal.

INTERMEDIJALNO PJESNIŠTVO HRVATSKOGA POSTMODERNITETA OD 1991. DO 2023.
Authors: Rem Goran
Published: March 2024

Rad prikazuje fenomene prijelaza kao strategije pjesničke intermedijalnosti u kontekstu jake Povijesti kao i njenih „slabih” reperkusija. Jaka Povijest, svojim egzistencijskim predmetnim nametanjem, sklanja figurativnost i Igru kao dominantno polje Pisma, pomiče te dvije kategorije u odmaknutije tekstne pozicije, a Igra i njezina kinetična predstavnica koreografije tekstualnih struktura nastoje i uspijevaju uspostaviti povratak polja dehijerarhizacije i vedrine. Rad pokazuje kako se iskustvima izložbe pojedinih poetskih tekstova u projektnim zahvatima, cijelosnih zbirki pa i opusa, ali i dragocjenim pretiscima avangardnih tekstova održava i kontinuira intermedijalitet, izlažući se svojevrsnome stanju prijelaza, ali i bitno aktivne umjetničke medijalne pismenosti. Središnja je svakako zbirka Branka Čegeca „Ekrani praznine“ iz 1992., zahvaćajući tragove vremena, kao i izložak Josipa Stošića „Čudo“; opusi pak Stojevića i Čegeca intenzivno vuku matrice intermedijaliteta kroz sve nove zbirke, a u rukopisima se autora koji su knjigovno nastupili u književnost nakon 1991. dade pratiti da je nekima intermedijalitet diskretno ritmiziran jedan od nosača opusa, nekima ekscesna jednoknjigovna kompaktna istraga radom jednoga rukopisa (Jurak, Radić, Brlo šić, Ivankovac…), a nekima stalni strukturni dio eruditskoga non-enciklopedizma (Sorel, Kukavica). Kontekst nove tehničke dominante internetovske uljudbe daje malu motivsku dopunu novim oblicima intermedijalnosti, ali još jače osvjetljava nekonkurentnost globalno dominantne tehnoznanosti pred humanistikom najmanjega književnog tekstnog opsega – poetskoga teksta, makar bio i romaneskni, kao i njegove intermedijalne mašte.

System for Selecting Tourist Routes Based on Genetic Programming
Authors:   Novosibirsk State University, Novosibirsk, 630090, Russian Federation, Khoroshavin A. K.
Published: March 2024

One of the most important tasks in tourism is helping tourists plan a trip to a given place. Since it is impossible to visit all places, tourists try to be rational and choose what they find most acceptable and attractive. Each plan has limitations (e. g., length of tour, limited budget) and preferences (e. g., art, culture, historical sites, architecture, modernism) that should be considered when planning your travel trip. This is a special case of the Orientation problem — Tourist trip design problem. The goal is to maximize the total score achieved within a given tour duration limit. This paper focuses on developing a recommendation system that considers users limitations during tour planning and their preferences. Since this problem is an NP-hard problem, heuristic algorithms such as the genetic algorithm (GA) are well suited for solving it. However, this algorithm can take a very long time to find the optimal solution, so this article focuses on developing a greedy strategy of GA to find optimal or near-optimal solutions. Instead of random genetic transformations, the algorithm consciously modifies optimal routes in order to find the desired tour for the users in a shorter time. After this, the developed algorithm was compared with a GA using various generated user profiles. Over 700 locations in Novosibirsk were used as a dataset for making recommendations. These modifications made it possible to obtain optimal routes faster than the standard implementation of the genetic algorithm.

In recent decades, environmental issues have become an area of greatest concern due to changes in global climate conditions. The transportation sector is a major contributor to carbon dioxide emissions, accounting for more than 22.9% of total carbon dioxide emissions. At present, most vehicles run on gasoline/diesel as fuel which is unsustainable and unviable as fossil fuels produce carbon emissions and fuel costs are rising. To address these issues, electric vehicles (EVs) offer an attractive solution as alternative to internal combustion engine vehicles that use electricity as an energy source. It is logical to use renewable energy to charge vehicles, which makes renewable energy an end-to-end clean energy source. In electric vehicles, energy conversion plays an important role. In the energy conversion process, alternating current (AC) can be converted to direct current (DC), or direct current can be converted to alternating current. In EV fast charging applications, DC-to-DC conversion is used, which requires DC-to-DC converters. In this paper, a detailed evaluation of the Buck-Boost and Single-Ended Primary Inductance Converters (SEPIC) with PV as input is analyzed for EV charging applications to make it end-to-end clean energy. For this purpose, a 5-by-5 PV system with a Buck-Boost, SEPIC converters with particle swarm optimization technique is considered, which is simulated in a MATLAB/SIMULINK environment. The simulation results showed that the ripples in output are minimal in SEPIC which supports the smooth and efficient charging of EV battery.

Aim of the study — to evaluate our own experience of the use of non-modular tapered stems in revision hip arthroplasty to determine the incidence and causes of repeated revisions, functional outcomes, and factors associated with subsidence of non-modular tapered stems.
Methods. We retrospectively analyzed the results of using 78 non-modular tapered stems. The average follow-up period was 5.1 years.
Results. There were repeated revisions accompanied by the removal of non-modular tapered stems in 14 (17.9%) cases. Significant subsidence was observed in 5 (6.4%) cases. Bicortical contact less than 2.0 cm (p = 0.017) was a risk factor for subsidence of non-modular tapered stems. The risk of having a bicortical contact of less than 2 cm was higher in patients with type IV femoral defect (p = 0.048). An improvement in functional parameters was found. Patients with significant subsidence of non-modular tapered stems had worse functional outcomes compared to patients without significant subsidence.
Conclusions. The use of non-modular tapered stems in revision hip arthroplasty shows good results in terms of repeated revision rates and functional outcomes. Periprosthetic infection and aseptic loosening were the most frequent causes of repeated revisions with removal of non-modular tapered stems. All patients with significant subsidence of non-modular tapered stems underwent repeated revision due to aseptic loosening. Bicortical contact less than 2.0 cm was a risk factor for significant subsidence of non-modular tapered stems. The risk of bicortical contact less than 2.0 cm was higher in patients with type IV femoral defects. Therefore, it is recommended to use non-modular tapered stems with caution or consider other hip reconstruction options in this type of defect.

The present article investigates the relationship between the microbiota of the oral cavity and oral mucositis induced by systemic antitumor therapy in patients with malignant neoplasms. This article highlights modern ideas about the composition of the normal microbiota of the oral cavity and its changes during chemotherapeutic treatment.
It has been shown that the normal oral microbiota includes representatives of such genera as Actinomyces, Corynebacterium, Fusobacterium, Leptotrichia, Neisseria, Prevotella, Streptococcus, and Veillonella. Moreover, it is emphasized that despite the existence of modern molecular genetic techniques and development of an oral microbiota database, determining the role of individual taxonomic units in oral homeostasis remains challenging.
Existing studies of changes in the qualitative and quantitative composition of oral microflora against the background of drug antitumor therapy have demonstrated that treatment is associated with significant changes in the microbiological landscape of the oral cavity. An increase was noted in the number of Gram-negative anaerobic opportunistic flora and a decrease in the representation of protective commensal flora. It has been demonstrated that the components of a bacterial cell can modulate the local reactions of a macroorganism through a system of Toll-like receptors while acting in different directions.
Several unresolved fundamental issues related to the role of oral microbiota in the pathogenesis of oral mucositis are highlighted.

Published: March 2024

The study aims to assess how solvency and liquidity affect profitability. Five conventional PCBs were used as a sample in the investigation using the judgmental sampling technique. This study is considered a five-year study period spanning from 2015 to 2019. Annual reports of sample banks and other pertinent sources have been consulted in collecting and utilizing secondary data. The study used multiple regression analysis to examine how various liquidity and solvency indicators affect profitability characteristics. The findings indicate that cash ratio, CAR, DER, and DAR do not significantly affect ROA, whereas CR and WCR do. Conversely, although CR, CAR, and DER significantly impact EPS, cash ratio, WCR, and DAR have no considerable effect on EPS.
The Development of the Korea-Japan Small-scale Imitation Bronze Mirrors in the Proto Three Kingdoms·Yayoi Period
Authors:   Korean Ancient Historical Society, Kang Chan
Published: March 2024

The ‘Small-scale Imitation Bronze Mirrors(小形仿製銅鏡)’ surveyed in Korea and Japan during the Proto Three Kingdoms·Yayoi(弥生) period have been assumed to have a one-way inflow from a specific area based on the frequency and distribution pattern of excavations. However, due to the lack of background and purpose of the Bronze Mirrors usage custom, the view that Korean excavations were obtained in Japan along with the making larger bronze weapon is drawing attention. This Yayoi social image and solidarity approach makes it difficult to make a balanced interpretation of Korean data. In particular, there is room for reconsideration when looking at relics by adding Korean data to the genealogical relationship between the early small-scale imitation bronze mirror mold and some patterns identified in Kyushu(九州).
Accordingly, this paper attempts to analyze the small-scale imitated bronze mirror found in Korea and Japan during the Proto Three Kingdoms Period based on formal studies to reveal the changes, and to clarify the diffusion structure and significance of objects through an approach considering the social background at that time.
There are eight main properties of the small-scale imitated bronze mirror, and a total of six forms can be derived by combining them. Each type is confirmed in both Korea and Japan, and the tendency to change according to the overall appearance shows high similarity regardless of region. However, differences can be confirmed in the patterns of major position, the shape around the ring(鈕座文樣), and the method of using the object.
In Korea, there are common cases in which it is accompanied by the chinese bronze mirrors(漢鏡), centered on the pattern of bracken designs(蕨手文) as a major use, but in Japan, the linked-arc designs(連弧文) is mainly used separately from the Chinese bronze mirror.
At the same time, in the process of sharing small-scale imitated mirrors, Korea shares exclusive ‘Prestige goods(威勢品)’ between cases in which Chinese bronze mirror or multiple small-scale imitated bronze mirror are buried, and plagiarization(盜用) is taking place around them.
On the other hand, in Japan, groups that do not own Chinese bronze mirror share a small-scale imitated bronze mirror, and theft and control of Chinese bronze mirror is carried out. These patterns of spread in each region are confirmed to be exclusive in a way that is not shared according to the form of burial of bronze mirror, but it was interpreted that multiple exchanges were made through particular change tendency in each region, the existence of the small-scale imitated bronze mirror which was made by same mold, and the similarity of the overall appearance.
A Position Paper on Paid Music Therapy Internships: An Analysis of Strengths, Weaknesses, Opportunities, and Threats to Initiate Dialogue
Authors: Silverman Michael
Published: March 2024

The music therapy internship represents the culmination of students’ clinical training. Currently, most music therapy internships are unpaid while other healthcare professions offer paid internship options or do not require an internship. The purpose of this position paper was to conduct a SWOT (strengths, weaknesses, opportunities, and threats) analysis and initiate dialogue regarding paid music therapy internships in the United States. Designed to initiate dialogue and conversation, this article is not a research paper. I conducted an initial SWOT analysis on paid music therapy internships. I then shared the analysis with music therapy students, internship directors, clinicians, business owners, and faculty and integrated their feedback. Although the SWOT analysis indicated that the current internship model can result in strong clinicians, there are weaknesses regarding workforce diversity, accessibility, and finances. There may be numerous opportunities for the profession to strengthen itself through paid internships. The profession’s mission and values regarding increased access to music therapy for service users, greater workforce diversity, and quality of care amid escalating tuition and cost of living expenses are consequential factors that may influence paid music therapy internships. Although paid internships may be beyond the control of clinical training directors and thus may not be feasible in all contexts, the large number of unpaid internships may hinder the music therapy profession from thriving and advancing toward its mission. The profession may have an opportunity to use its own agency by valuing itself through paid music therapy internships. Questions and considerations are provided to conclude the paper.

Bu çalışmanın amacı; örgütsel adalet ve kontrol odağının örgütsel yabancılaşma üzerindeki etkisine ve kontrol odağının örgütsel adalet ile örgütsel yabancılaşma arasındaki düzenleyici rolünü test etmeye yöneliktir. Hatay’daki özel hastane çalışanlarına anket yapılmış, Yapısal Eşitlik Modeli yoluyla test edilmeye çalışılmıştır. Araştırma sonucunda; çalışanlardaki örgütsel adalet algıları ve örgütsel yabancılaşma arasında negatif yönlü ilişki tespit edilmiştir. İçsel kontrol odağının örgütsel yabancılaşmayı olumsuz etkilediği görülmüştür. Örgütsel adalet ile iç kontrol odağı arasında olumlu ilişki olduğu yönündeki hipotez desteklenmiş, dışsal kontrol odağı ile örgütsel adalet arasında olumsuz ilişki olduğu yönündeki hipotez desteklenmemiştir. Ayrıca etkileşim analizleri sonucunda örgütsel adalet ile örgütsel yabancılaşma arasındaki ilişkide içsel kontrol odağının düzenleyici rolüne bakılmış; içsel kontrol odağı yüksek olanlarda örgütsel adaletin, örgütsel yabancılaşmaya etkisi olumsuz iken; içsel kontrol odağı düşük olanlarda örgütsel adaletin örgütsel yabancılaşmaya etkisi olumlu bulunmuştur. Dışsal kontrol odağı düşük olan çalışanların örgütsel yabancılaşmaları, algılanan örgütsel adalete karşı daha duyarlı bulunmuştur.

Published: March 2024

This paper reports a pilot study upon segmental and super-segmental deviations of 40 Chinese English as a Foreign Language (EFL) learners’ sentence imitation task. The researchers annotated all substitute phonemes and tones for each observed phoneme and tone in the imitation task to describe some phonetic features of the norm of China English Accent (CEA), and probe for the dividing line between CEA and errors. Some carriers of CEA have been observed on the base of the data analysis to describe parts of the norm of CEA upon which a tentative dividing line was drawn between CEA and errors. Some pedagogical reflections were made to cast upon English teaching. Teacher’s stance towards CEA was discussed.

Published: March 2024

Quarter car model is the simplest way for the analysis of vehicle suspension system. The objective of this study is to propose the natural frequency and to identify the displacement analysis of 3 Degree of Freedom (3DOF) suspension system using Matlab software. Research methodology are state space modelling method and logarithmic decrement method. From the state space modelling, seat mass, sprung mass and unsprung mass displacement have been calculated. Logarithmic decrement method is a time domain technique to obtain experimental damping ratio. The novelty of this research has demonstrated the experimental approach by using Quantum X (catman AP v5 software). Natural frequency and acceleration results are obtained from the time domain response of experimental data. The value of sprung mass natural frequency for theoretical (1.23 Hz) and experimental (1.134 Hz) result are within 1Hz to 2Hz. The maximum displacement transmissibility values for theoretical (2.7) and experimental (2.54) approach are less than the reference value (3.5) at the resonance point. The findings demonstrated that the results of natural frequency and damping ratio are within the acceptable limit. So, the obtained results are validated the suspension system of Nissan Sunny model for vehicle safety and passenger comfort.
