Development and Initial Validation of a Career Preference Scale (CPS-15F): An Underlying Model of Holland's Theory for Measuring Career Interests
Authors: Zemzami Mountassir , Lotfi Said
Published: April 2024

The aim of this study is to develop a career preference scale that requires the study of existing theories of occupational interest evaluation (Strong, Kuder, Holland and Rothwell Miller) while analyzing their structures, their item selection methods and the response methods proposed in this type of construct, This qualitative analysis enabled us to conclude that Holland's method of classifying professional interests is the best suited to the context of the evaluation in order to establish an underlying model of 15 sub-factors making it possible to measure Holland's inter-dimensional relationships and to deduce clear preferences from them on the basis of a suitable structure and response mode, and to interpret the results pertinently thanks to the 24 professional profiles presented in this study. We also studied the psychometric qualities of the career preference scale developed, which was administered to a sample of 628 participants. The validity of the scale was verified empirically by measuring item-test correlations and internal consistency independently for each sub-factor, Fidelity was verified using a test-retest with a sample of 50 participants, while concurrent validity was verified by relating the dimensions of interest to other information (gender and field of study of the students) to check the relationship with the literature. These procedures demonstrated satisfactory psychometric qualities and enabled six items on the scale to be improved for a more relevant assessment and to be used in the school and professional environment.

Authors: Aldahadha Basim , Al Dwakat Mohammad
Published: April 2024

This study aimed to collect the largest possible number of items from the Islamic literature. The validity of these items was verified by a sample of experts and academics (N=21). Through in-depth interviews using Delphi procedures, 59 items were derived as an initial list for the scale. After several statistical analyses, including EFA and CFA, they were reduced to 32 items. The results of EFA (N=369) showed three main factors for Islamic Temporal Focus Scale (ITFS) extraction with a sum of squared loading of 64.51%. For the third sample (N=439), which was used for CFA, three factors confirmed the convergent validity of this scale, which is related to the Arab Scale of Happiness, the Measure of Reverence in Muslim Prayer, and the DASS-21, including the factors of depression, anxiety, and psychological stress. The results showed that the reliability values were stable. The values of Cronbach’s alpha were 0.780 for the past factor, 0.920 for the present factor, and 0.810 for the future factor. With regard to the split-half reliability of each of the three factors, the results showed that the stability coefficient was 0.820 for the past factor, 0.890 for the present factor, and 0.750 for the future factor. Therefore, the ITFS provides suitable evaluation and integration with past, present, or future factors. It has health and psychological implications and scientific value for future studies that can link it to variables such as mindfulness as well as psychological and physical disorders.

Published: April 2024

The development of students’ social skills is critical since they influence their academic performance and achievement.  School provides optimal environment for students to learn these skills.  Even though social skills are critical, there is still a lack in past research that examines the aspects that contribute to the development of students' social skills, particularly in school. Recognising the importance of this, the focus of this study is to identify characteristics that influence the development of social skills from a social cognitive perspective. This study sought to investigate the impact of emotional intelligence, teacher-student connections, student voice, and friendship quality on students’ social skills at school. The method utilised was a survey with multistage random sampling. The study sample comprised of 1012 students aged 11 to 19 who were recruited at random from various schools in major Indonesian cities. The research instruments used in this study were emotional intelligence scale, teacher-student relationship scale, student voice scale, friendship quality scale, and social skills scale. The analysis technique used is the SEM model (structural equation model) with the Variance based matric structural equation modelling (VB-SEM) structural equation model. The results showed emotional intelligence, teacher-student relationships, student voice, and friendship quality had in impact on students’ social skills.

Published: April 2024

People living with Human Immunodeficiency Virus (PLHIV) frequently encounter adverse circumstances, including depression and feelings of inadequacy. The stigma associated with their condition often leads to feelings of shame, isolation, and a diminished zest for life.  These adverse conditions are known to significantly impact the psychological well-being of PLHIV. This study seeks to scrutinize the relationship between emotional intelligence and social support is mediated by gratitude. The research was carried out in East Kalimantan Province. A quantitative methodology was employed in this investigation. The study encompassed PLHIV who receive support from the Mahakam Plus Community Initiators in Samarinda, Indonesia. The data collection process involved four distinct questionnaires, focusing on emotional intelligence, social support, gratitude, and psychological well-being. In analyzing the gathered data, a path analysis technique was employed. The research findings revealed that gratitude plays a pivotal role as a mediating factor capable of bridging the relationship between social support on psychological well-being and mediating the influence of emotional intelligence on psychological well-being. The model of psychological well-being among PLHIV in this study aligns closely with empirical data. This alignment is evidenced by a standardized root mean square residual (SRMR) value of 0.100, a Q value greater than zero, and a model goodness-of-fit (GoF) score of 0.483. Moreover, the study uncovered that emotional intelligence, social social support, and gratitude exert a positive and statistically significant influence on psychological well-being. The study underscored the critical role of gratitude as a mediating variable. The implications of these findings in terms of potential strategies and interventions for enhancing the psychological well-being of PLHIV are thoroughly discussed.

Authors: Srijundaree Pal , Yurayat Phamornpun , Nipanan Pairat
Published: April 2024

The rapid growth of online counseling (OC) services for mental health during the COVID-19 pandemic prompted concerns regarding its effectiveness compared to in-person counseling. Psychologists have expressed uncertainties about OC's efficacy and doubts about their competence in using it. As a result, psychologists have been hesitant to embrace OC methods and supporting technologies. Therefore, it has become crucial to study the factors that influence the acceptance and use of OC technology, enabling psychologists to develop the necessary skills and confidence to utilize inpatient treatment effectively. This study used quantitative research with survey research to study factors influencing 406 Thai counselors' use and acceptance of technology in online counseling, and the model was analyzed using structural equation modeling. Results showed that IOC are positively influenced by SI (β= .413, p<.001, t = 9.95) ATOC (β= .398, p<.001, t = 7.09), and PE (β= .114, p<.05, t = 2.01). While IOC is negatively influenced by FC (β= -.117, p<.05, t = -2.08). Furthermore, UOC was positively influenced by IOC (β= .511, p<.001, t = 9.64). On the contrary ATOC negatively affected UOC (β= -.215, p<.001, t = -3.77), indicating that it exerts a partial mediation effect on the relationship between PE, SI, FC, ATOC and UOC. The study represents a pioneering study on UTAUT use in determining technologies' influence on online mental health counseling in Southeast Asia. The findings could offer valuable perspectives on how to increase the uptake of online counseling among psychologists by elevating the perceived advantages of the service, assisting in the creation of more efficient, organizations or authorities that foster positive attitudes toward the use of online counseling among psychologists, and fostering increased acceptance and usage of online counseling going forward.
Peripheral Arterial Disease in Diabetes and its Relation to Cardiovascular Risk Factors in Women
Authors: Vanamali Dharma Rao , Gara Himavathy Kodandarao
Published: April 2024

Objectives:

Peripheral arterial disease (PAD) is characterized by occlusive disease in the abdominal aorta, iliac, and femoral arteries, leading to reduced blood flow and complications. Diabetes mellitus (DM) is known to contribute to the development and progression of PAD due to factors such as hyperglycemia, dyslipidemia, endothelial dysfunction, and inflammation. However, PAD may be underdiagnosed in women with DM, leading to adverse cardiovascular outcomes. The present study aimed to investigate the prevalence of PAD in women with type 2 DM (T2DM) and its relationship with cardiovascular risk factors.

Materials and Methods:

This hospital-based, cross-sectional, and observational study was conducted for a period of 3 months from June 10, 2023, to September 10, 2023, in the outpatient department of general medicine. After obtaining the approval from the Institutional Ethical Committee, the study was performed according to the Declarations of Helsinki and Good Clinical Practice requirements for human subject protection. Non-probability purposive sampling technique was used to enroll participants. Participants underwent face-to-face interviews and clinical examinations. Sociodemographic data, medical history, and pharmacotherapy details were collected. Laboratory investigations were conducted, including blood glucose, lipid profile, and glycosylated hemoglobin (HbA1C) tests. The ankle-brachial index (ABI) was measured.

Results:

The results showed that the majority of the participants were between 50 and 70 years of age, married, and had a high school education. Participants had an average body mass index (BMI) indicating overweight, and the average duration of diabetes was 6.571 years. Hypertension was the most prevalent comorbidity. Overweight, obesity I, and obesity II were present in 15.25% (n = 19), 33.6% (n = 42), and 8.8% (n = 11), respectively. Average values for HbA1C, fasting blood glucose (FBG), and postprandial blood glucose (PPBG) were within the diabetic range. ABI was normal in the right side, left side, and bilateral in 43.2%, 56%, and 14.4% of participants, respectively. ABI was borderline on the right side, left side, and bilateral in 40.8%, 36.8%, and 22.4% of participants, respectively. PAD was observed on the right side, left side, and bilateral in 16%, 7.2%, and 4% of participants, respectively. BMI, duration of DM, glycosylated hemoglobin, FBG, and PPBG showed significant negative correlations with ABI. Age, triglycerides, high-density lipoprotein, and low-density lipoprotein did not show any statistically significant correlation with ABI.

Conclusion:

The study highlighted the importance of screening for PAD in women with T2DM to improve cardiovascular outcomes. The findings shed light on the prevalence of risk factors for PAD and their association with the disease. These insights can contribute to the development of targeted interventions to reduce adverse clinical outcomes in this population.
Non-invasive efficacy assessment of pulsed dye laser and photodynamic therapy for port-wine stain
Authors: Tian Rongqian , Wang Qin , Li Sijin , Nong Xiang
Published: April 2024

Port wine stain (PWS) is a congenital vascular malformation that commonly occurs on the face and neck. Currently, the main treatments for port wine stain are pulsed dye laser (PDL) and photodynamic therapy (PDT). However, the efficacy evaluation of PWS mostly relies on the subjective judgement of clinicians, and it is difficult to accurately respond to many small changes after treatment. Therefore, some non-invasive and efficient efficacy assessment methods are also needed. With the continuous development of technology, there are currently many visualisation instruments to evaluate PWS, including dermoscopy, VISIA-CR™ system, reflectance confocal microscopy (RCM), high-frequency ultrasound (HFUS), optical coherence tomography (OCT), Photoacoustic imaging (PAI), laser speckle imaging (LSI) and laser Doppler imaging (LDI). Among them, there are simple and low-cost technologies such as dermoscopy and the VISIA-CR™ system, but they may not be able to observe the deeper structures of PWS. At this time, combining techniques such as HFUS and OCT to increase penetration depth is crucial to evaluate PWS. In the future, the combination of these different technologies could help overcome the limitations of a single technology. This article provides a systematic overview of non-invasive methods for evaluating treatment efficacy in port wine stains and summarises their advantages and disadvantages.

Authors: Basabih Masyitoh , Widhakuswara Indriaswari
Published: April 2024

The Policy of the Regional Public Service Agency (Badan Layanan Umum Daerah or BLUD) is a form of autonomy for Regional Public Hospitals (Rumah Sakit Umum Daerah or RSD) born from healthcare service reforms. Despite being implemented for over two decades, several challenges in persist policy implementation. This research aims to analyze the opportunities and challenges in implementing the BLUD policy in RSD within the context of public services. The research method employed is a systematic review using inclusion criteria. Searches were conducted using the keywords policy implementation, BLUD, and RSD, utilizing the Garuda database and Google Scholar. This systematic review analyzes articles published from 2007 to 2022. The study identifies challenges such as resource quality, organizational fragmentation, and suboptimal communication. On the other hand, there is evidence of positive acceptance or response from implementers towards the BLUD policy. Based on the analysis, it can be concluded that the BLUD policy provides opportunities for RSD to enhance performance through its flexibility. Human resource capacity and communication pose challenges in BLUD policy implementation within RSDs. Implement targeted training programs for both regional governments and hospitals should address the specific needs and challenges of BLUD implementation, such as potential knowledge gaps arising from differing educational backgrounds.

Published: April 2024

Female sex workers carry out sexual transactions that pose a high risk to their health. They experience a high risk of health problems, especially transmission of sexually transmitted infections. There are various factors that female sex workers (FSW) carry out sexual transactions with frequent frequency, such as poverty, gender inequality, and limited access to productive assets. This study aims to determine the associated between the frequency of sex transactions and health risks. This research uses a quantitative approach with a cross-sectional design. The population of this study was all female sexual workers (FSW), with a sample size of 162 taken by purposive sampling. The results of this study show that the majority of FSWs have had a sexual transaction frequency more than two times in the last week, amounting to 79.5%, with a prevalence of high health risks of 75.9%. Based on the multivariate test, it is known that the frequency of sexual transactions is associated with health risks after controlling for the variables age and length of time as a FSW with an Adjusted Odds Ratio of 3.467 (1.415-8.494). Health risks FSW who engage in sexual transactions more than two times have a risk of 3.467 (1.415-8.494) times experiencing high health risks compared to female sex workers who engage in sexual transactions less than two times after controlling for age and length of time as female sex workers. When carrying out work in sexual exploration, FSW should continue to use sexual protective equipment and carry out regular health checks, especially for sexually transmitted infections.

Authors: Marciniak Marian , Szczęsny Waldemar
Published: April 2024

In the paper results of analysis of nonlinear phenomena in optical fibres: Self-Phase Modulation, Cross-Phase Modulation, Four-Wave Mixing and Stimulated Raman Scattering and their influence on Dense-Wavelength Division Multiplexed system performance are reported. Different non-uniform optical channel allocation schemes based on ITU Recommendation G.692 100 GHz frequency grid are compared with uniform channel distribution. The level of nonlinear cross-talk is determined for different levels of the total optical power. As an example a 10 Gbit/s D-WDM dispersion-shifted single mode fibre link with dispersion-compensating fibres is envisaged. The directions for optimization of the system design in view of actual international standardization trends are pointed out.

Control of the effects of crystal dispersion at different orders in the mixing of three phase-matched waves on a 5- to 100-fs time scale
Authors: Andreoni Alessandra , Bondani Maria , Potenza Marco A.C.
Published: April 2024

A number of manners to obtain first-order achromatic phase matching of both type I and type II are presented and the most advantageous ones are identified to generate high-spectral quality 100-fs pulses by either parametric generation or frequency up-conversion. In the case of frequency-doubling high-energy 5-fs Ti:sapphire pulses, a non-collinear phase-matching I geometry in a b-barium borate crystal cut at 44 deg is devised that should allow high conversion efficiency, virtually without pulse lengthening and intra-pulse frequency chirp due to group-velocity dispersion.

Reflection from layered dielectric structures with combined regular and random inhomogeneities
Authors: Guzev Michael A. , Popov Gennadiy V.
Published: April 2024

Optical wave reflection from a layered half-space with regular and random inhomogeneities where the regular perturbations correspond to a linear waveguide near the half-space boundary. Random inhomogeneities are simulated in the frame of the white noise model. The problem is solved analytically in a framework of the embedding method which reduces a boundary problem to the problem with initial values considering the field as a function of the half-space boundary coordinate and obtaining then its solution as a steady-state probability density of the reflection coefficient phase. Numerical calculations revealed some features of the field behaviour under the combined influence of regular and random inhomogeneities such as the reflection coefficient phase increasing inhomogeneity from uniform distribution for small regular inhomogeneities toward a strong peak at the phase equal to pi/2 for increasing ones, and some fine effects which are still greater then the calculation accuracy.

Optical range electromagnetic field interaction with inhomogeneous finite dielectric media is investigated. New method for analysis of this interaction in 1D case based on integral equations for fields in transient media is proposed. Some special cases of quasi-periodical structures with doubled quasi-periodicity are investigated numerically. A possibility to obtain good filtering properties in such structures for small number of quasi-periods is shown.

Published: April 2024

The high frequency performances including microwave noise parameters for sub-quarter micron fully- (FD) and partially-depleted (PD) silicon-on-insulator (SOI) n-MOSFETs are described and compared. Direct extraction techniques based on the physical meaning of each small-signal and noise model element are used to extract the microwave characteristics of various FD and PD SOI n-MOSFETs with different channel lengths and widths. TiSi2 silicidation process has been demonstrated very efficient to reduce the sheet and contact resistances of gate, source and drain transistor regions. 0.25 um FD SOI n-MOSFETs with a total gate width of 100 um present a state-of-the-art minimum noise figure of 0.8 dB and high associated gain of 13 dB at 6 GHz for Vds=0.75
Direct extraction techniques of microwave small-signal model and technological parameters for sub-quarter micron SOI MOSFETs
Authors: Goffioul Michel , Vanhoenacker Danielle , Raskin Jean-Pierre
Published: April 2024

Original extraction techniques of microwave small-signal model and technological parameters for SOI MOSFETs are presented. The characterization method combines careful design of probing and calibration structures, rigorous in situ calibration and a powerful direct extraction method. The proposed characterization procedure is directly based on the physical meaning of each small-signal model element. Knowing the qualitative small-signal behavior of each model parameter versus bias conditions, the high frequency equivalent circuit can be simplified for extraction purposes. Biasing MOSFETs under depletion, strong inversion and saturation conditions, certain technological parameters and microwave small-signal elements can be extracted directly from the measured S-parameters. These new extraction techniques allow us to understand deeply the behavior of the sub-quarter micron SOI MOSFETs in microwave domain and to control their fabrication process

Published: April 2024

The technology of CMOS large-scale integrated circuits (LSI`s) achieved remarkable advances over last 25 year and the progress is expected to continue well into the next century. The progress has been driven by the downsizing of the active devices such as MOSFETs. Approaching these dimensions, MOSFET characteristics cannot be accurately predicted using classical modeling methods currently used in the most common MOSFET models such as BSIM, MM9 etc, without introducing large number of empirical parameters. Various physical effects that needed to be considered while modeling UDSM devices: quantization of the inversion layer, mobility degradation, carrier velocity saturation and overshoot, polydepletion effects, bias dependent source/drain resistances and capacitances, vertical and lateral doping profiles, etc. In this paper, we will discuss the progress in the CMOS technology and the anticipated difficulties of the sub-0.25 um LSI downsizing. Subsequently, basic MOSFET modeling methodologies that are more appropriate for UDSM MOSFETs will be presented as well. The advances in compact MOSFET devices will be illustrated using application examples of the EPFL EKV model
Roadmap for SiC power devices
Authors: Bakowski Mietek
Published: April 2024

Silicon carbide (SiC) power devices offer significant benefits of improved efficiency, dynamic performance and reliability of electronic and electric systems. The challenges and prospects of SiC power device development are reviewed considering different device types. A close correlation between an exponential increase of current handling capability during recent five years and improvement in substrate quality is demonstrated. The voltage range of silicon and SiC unipolar and bipolar power devices with respect to the on-state voltage is determined based on device simulation. 4H-SiC unipolar devices are potentially superior to all silicon devices up to 10 kV. 4H-SiC unipolar devices are superior to all SiC bipolar devices up to 8-9 kV. The low end of SiC unipolar devices is determined to be around 200 V provided substrate resistance is reduced by thinning the substrate down to 100 um. The influence of reduced channel mobility on the specific on-state resistance of 4H-SiC DMOSFETs and UMOSFETs is shown. It has been demonstrated that 6H-SiC DMOSFETs could be a better choice compared to 4H-SiC MOSFETs in the voltage range below 600 V utilising better channel mobility obtainable so far on 6H-SiC polytype. An impact of super junction (SJ) concept on silicon and SiC MOSFET specific on-resistance limits is demonstrated
