Investigation of differences between the representatives of the high-to moderate functional status according to upper limb functions and participation in children with congenital hemiplegic cerebral palsy: A cross-sectional study
No full textThis study aimed to explore the acquisition of manual ability and participation performance in individuals
with cerebral palsy (CP) in the context of classification systems. In other words, the aim was to determine whether
the three representatives of functional status in individuals with CP differed according to manual ability and
participation outcomes. Seventy-one individuals (mean 12.4 SD 2.3 years; 38 boys and 33 girls) diagnosed with CP
were enrolled. The functional status of the study participants was defined using the Manual Ability Classification
System (MACS), Gross Motor Function Classification System Expanded &Revised (GMFCS-E&R), and
Communication Function Classification System (CFCS). Manual ability and participation outcomes were
documented using the ABILHAND-Kids and Child and Adolescent Scales of Participation (CASP), respectively.
Post-hoc tests demonstrated that individuals with high MACS and GMFCS-E&R levels had higher scores on the
ABILHAND-Kids and CASP than those with low MACS and GMFCS-E&R levels (I>II>III, P<0.0001). Likewise,
individuals in CFCS I scored better on both the ABILHAND-Kids and CASP than those in CFCS III (I>III,
P<0.001). In contrast, ABILHAND-Kids and CASP scores were similar in individuals classified as CFCS I-II or
CFCS II-III (P>0.05). Finally, multiple regression analyses revealed that MACS and GMFCS-E&R strongly
predicted manual ability (MACS:65%; GMFCS-E&R: 23%) and participation outcomes (MACS: 46%-62%;
GMFCS-E&R: 57%-68%). Knowledge from MACS and GMFCS-E&R can provide insight into the manual ability
and participation outcomes of individuals with CP.Bu çalışmanın amacı, sınıflandırma sistemleri bağlamında Serebral Palsili (SP) bireylerde el becerisi ve

Evaluation of rail transportation stops efficiency in Antalya by applying intuitionistic Fuzzy TOPSIS analysis
No full textEnsuring comfort, safety, security, and accessibility in public transportation
(PT) systems is essential for promoting equitable access and inclusivity,
especially within urban rail networks. This study evaluates the efficiency
of tram stops in Antalya’s urban rail system by employing an application
of multi-criteria decision-making (MCDM) method, Intuitionistic Fuzzy
Technique for Order Preference by Similarity to Ideal Solution (Intuitionistic
Fuzzy TOPSIS) analysis. The research focuses on the first tram line in
Antalya, examining its stops in central areas. Evaluations encompass various
aspects including comfort, safety, security, and accessibility. Particularly,
comfort levels are assessed based on the availability of amenities surrounding
tram stops. Safety is evaluated by analyzing the density and proximity of bus
stops, while security measures consider street lighting adequacy. Additionally,
accessibility for disabled individuals is examined, particularly regarding
the presence of stairs. This investigation centers on the Antalya tram line
as a case study, comprising 16 stops, thereby presenting 16 alternatives for
analysis. Three experts participate in the evaluation process, deploying four
established criteria. Results indicate variations in efficiency among stops,
with recommendations provided for improvement. By addressing critical
factors and utilizing MCDM methods, this research contributes to enhancing
PT services in Antalya, fostering a more efficient and inclusive urban transit

Metaheuristic algorithms and multi-criteria decision-making for urban public transportation systems in developing tourism environment
No full textA number of structures, including public transportation (PT) structures and facilities, have been built in the large cities in order to protect and develop tourism. The importance of them is recognized day-to-day and the value they add to the economy of the city increases. In particular, efforts to protect historical PT system structures stand
out. While there are many studies in many urban areas in order to preserve the historical structure in transportation, the assessment procedures are crucial in these cases. Although many alternatives are compared by applying multi-criteria decision-making (MCDM) methods in the field of transportation, other techniques such as metaheuristic techniques in transportation optimization can also be utilized. Not only these advanced
methodologies can be used together, also decision-makers in urban transportation can put these methods into practice. Therefore, in this study, a set of transportation measures are evaluated by three up-to-date metaheuristic algorithms and an MCDM technique. They are applied for maintaining a PT line which has been used for years to develop tourism. The line remains robust in today's conditions, however it should be carried into the future. In other words, this study is a comparison of alternatives with
metaheuristic algorithmic applications and MCDM methods.No sponso
Factors influencing adherence to Physical Exercise in patients with multiple sclerosis: a systematic review focusing on Exercise over General Physical Activity
No full textBackground While the barriers and facilitators of physical activity adherence are well-defined, there is a limited number of
studies focusing specifically on exercise adherence, which is crucial to identify in patients with multiple sclerosis (MS) due
to its known disease-modifying effect.
Objective To investigate the factors affecting adherence to physical exercise in MS patients.
Methods Literature search was conducted in PubMed, Cochrane, Web of Science, and Scopus electronic databases up to
the current date. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS) for quantitative studies and
the McMaster Critical Appraisal Tool for qualitative studies, with evidence synthesis conducted using the Modified Bakker
Scale.
Results The systematic review incorporated thirteen studies, consisting of seven qualitative and six quantitative ones. These
studies’ methodological quality was high; 12 were high, and the other was medium (unclear). In all reviewed studies,
the primary patient-related and environmental barriers with high levels of evidence regarding exercise adherence included
fatigue (38%), false beliefs (18%), cost (18%), and lack of time (15%). Barriers identified in very few studies included cognitive problems (3%), bladder-bowel problems (3%), and family support and advice (3%), indicating a necessity for further
research to reveal their impact on exercise adherence.
Conclusion The scarcity of studies on exercise barriers in MS is partly due to the absence of reliable assessment methods for
evaluating exercise adherence, along with the prevalent emphasis on physical activity. Future research should prioritize the
development of adherence scales tailored to physical exercise and shifting focus towards less explored barriers
Temperature dependence of THz generation efficiency, THz refractive index, and THz absorption in lithium-niobate around 275 GHz
No full textIn this study, we demonstrate the capabilities of the pulse train excitation approach in
determining key material properties of nonlinear crystals, such as refractive index, thermo-optic
coefficient, and absorption. The method provides reliable results even at relatively low THz
frequencies, where other characterization methods, such as THz time-domain spectroscopy, have
difficulties. To illustrate the capabilities of our approach, we used pulse trains with 800-fs long
pulses and adjustable time delay to investigate the material properties of periodically poled
lithium niobate (PPLN) crystal with a poling period of 400 µm. Via scanning the incident
pulse-train frequency, we measured the frequency response of the crystal at different temperatures
(78-350 K), which enabled us to determine the temperature dependence of the refractive index
and thermo-optic coefficient of the PPLN crystal around 275 GHz with very high precision. We
further studied the variation of THz generation efficiency with temperature in detail to understand
the temperature dependence of THz absorption in PPLN material. The technique employed is
quite general and could be applied to both other frequency ranges and nonlinear crystals.No sponso
Fractional thermal load in cryogenically cooled Yb:YLF and Yb:YAG lasers
No full textWe present a method for the direct measurement of the fractional thermal load (FTL) in cryogenically cooled laser crystals. The experimental methodology involves characterizing the liquid nitrogen evaporation rate in a dewar containing the laser crystals, allowing for the accurate
determination of FTL. The FTL is measured to be 1.7 × quantum defect (QD) for Yb:YLF and 1.5 × QD for Yb:YAG under continuous wave lasing conditions. The measured FTL values are then used to calculate the temperature distribution inside the crystals as a function of pump power,
and the simulation results are found to be in very good agreement with the in-situ temperature measurements using contactless optical luminescence thermometry. The method and findings presented in this work hold great potential to benefit laser engineers and scientists working with cryogenic lasers to address and overcome temperature-dependent handicaps.No sponso
