Modeling the Correlation of Human Vertebral Body Volumes

Balázs Benyó Péter Somogyi Bálint Szabó Katalin Kovács Sándor Bazsó Ákos Szlávecz Árpád Viola

Publication Name: IFAC Papersonline

Publication Date: 2023-07-01

Volume: 56

Issue: 2

Page Range: 9030-9035

Description:

Anatomical parameters of the human body strongly correlate with each other. Modelling these dependencies enables the creation of a realistic anatomical human body model that can be parameterized. Such a model can be used for several diagnostic processes to identify abnormalities or even give guidance in surgical interventions. This paper proposes a probabilistic model describing the dependencies between the vertebral body volumes of humans from the Caucasian human race. As demonstrated, the proposed model can accurately describe the relationship between the vertebral body volumes and is used for the prediction of an unknown vertebral volume based on a known one. The probabilistic model is created by using the CT segmentation of 37 patients.

Health and health-related behaviour of future and graduated professional female nurses and doctors

Kovácsné Tóth Ágnes Helga Judit Feith Péter Balázs

Publication Name: Mentalhigiene Es Pszichoszomatika

Publication Date: 2008-01-01

Volume: 9

Issue: 4

Page Range: 289-304

Description:

Medical and nursing professions are stressing due to a number of major problems: high work related expectations, inadequate workplace conditions, the severe psychological burden placed on employees by the nature of their job. This study analyses the self-rated general and psychosocial health of female students and professional physicians and nurses related to healthy lifestyle habits and individual behavioural patterns. Method: our cross-section research was carried out among female nursing college students (N = 226), female medical students (N = 117), and among professional nurses and female doctors in hospitals (N = 409). Results: six out of ten staff members mentioned at least one health problem. To the self-rated health (SRH) of students and professional doctors and nursing staff were strongly related psychosomatic symptoms (p<0,001), pessimistic future expectations (p<0,001), perceived difficulties while maintaining the actual partnership (p = 0,001), and physical activity (p<0,001). About 40% (in student surveys 47,0%) said that they did some sports once a week or even more frequently. Smokers were represented with 16,7% (in student surveys 22,9%). Conclusion: results obtained suggest that health is not a highly appreciated value among female students and staff members in the Hungarian health care, moreover, their health-related behaviour is at a substandard level. Their roles as a social model in health promotion are rather questionable, for their insufficient health and risk behaviours. © 2008 Akadémiai Kiadó.

Private banking market developments: Evidence from Hungary

Eszter Kazinczy

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 12

Page Range: Unknown

Description:

Private banking institutions serve the financial sector’s wealthiest clientele via a dedicated value proposition. Based on the relevant tendencies and statistics, a remarkable expansion can be outlined since the mid-1990s. The aim of this study is to elaborate the Hungarian private banking market’s development as a case study. The paper also intends to add to the literature on this unique segment of the financial market. Based on the available statistics, the analysis primarily focuses on the Hungarian private banking market’s rapid development process. This can be underpinned by the clientele’s savings, number of accounts and respective segmentation limits of the institutions. Referring to the amount of savings, a correlation analysis indicates significant co-movements with specific social and economic variables. The growth rate of the Hungarian clientele’s savings outperformed the respective indicator in Western Europe during the review time period (2007–2020). The current paper also includes a section that summarises general challenges that private banking managers need to address during the development process. Generally, the literature on private banking can still be considered scarce, whereas there is a lack of studies on the Central-Eastern European region. The analysis of the Hungarian sector’s development path can serve with relevant information to any financial expert in the field.

Adaptive Adjustments in Lower Limb Muscle Coordination during Single-Leg Landing Tasks in Latin Dancers

János Gál Yaodong Gu Gusztáv Fekete Minjun Liang Datao Xu Xiangli Gao Tianle Jie

Publication Name: Biomimetics

Publication Date: 2024-08-01

Volume: 9

Issue: 8

Page Range: Unknown

Description:

Previous research has primarily focused on evaluating the activity of individual muscles in dancers, often neglecting their synergistic interactions. Investigating the differences in lower limb muscle synergy during landing between dancers and healthy controls will contribute to a comprehensive understanding of their neuromuscular control patterns. This study enrolled 22 Latin dancers and 22 healthy participants, who performed a task involving landing from a 30 cm high platform. The data were collected using Vicon systems, force plates, and electromyography (EMG). The processed EMG data were subjected to non-negative matrix factorization (NNMF) for decomposition, followed by classification using K-means clustering algorithm and Pearson correlation coefficients. Three synergies were extracted for both Latin dancers and healthy participants. Synergy 1 showed increased contributions from the tibialis anterior (p < 0.001) and medial gastrocnemius (p = 0.024) in Latin dancers compared to healthy participants. Synergy 3 highlighted significantly greater contributions from the vastus lateralis in healthy participants compared to Latin dancers (p = 0.039). This study demonstrates that Latin dancers exhibit muscle synergies similar to those observed in healthy controls, revealing specific adjustments in the tibialis anterior and medial gastrocnemius muscles among dancers. This research illustrates how dancers optimize control strategies during landing tasks, offering a novel perspective for comprehensively understanding dancers’ neuromuscular control patterns.

Placebo and nocebo interventions impact perceived but not actual proprioceptive accuracy

Ferenc Köteles Orsolya Drozdovszky Áron Horváth Blanka Aranyosy Attila Szabo

Publication Name: Plos One

Publication Date: 2024-08-01

Volume: 19

Issue: 8

Page Range: Unknown

Description:

Changes in performance caused by positive and negative expectations (i.e., placebo and nocebo responses) were found to play an important role in many aspects of motor performance. This study aimed to test the impact of placebo/nocebo responses and the assumed moderating role of dispositional optimism and anxiety on proprioceptive accuracy, an essential aspect of motor functions. 78 undergraduate university students completed questionnaires assessing dispositional optimism, state anxiety, and motivation to cooperate, then were randomly assigned to three experimental groups. A sham subliminal electric stimulation was applied with claimed positive (placebo group, n = 26), negative (nocebo group, n = 26) or neutral (control group, n = 26) impact on proprioceptive accuracy. Proprioceptive accuracy was measured with active and passive versions of the Joint Position Reproduction task before and after the intervention. Expected and perceived changes in performance were also assessed; changes in state anxiety, optimism, and motivation to cooperate were used as control variables (covariates). Mixed analyses of variance indicated that the experimental manipulation did not affect actual proprioceptive accuracy but impacted expected and perceived performance. Adding the covariates to the models did not substantially change the results. Further, no significant association emerged between actual and perceived change in performance in the active test, and only a weak correlation was found in the passive test. Expected performance did not predict actual performance but predicted perceived performance in both tasks. The results suggest that only perceived (subjective) aspects of proprioceptive accuracy are susceptible to placebo and nocebo interventions.

Hungarian Territorial Changes and Nationality Issues Following World War I

Mónika Ganczer

Publication Name: Hungarian Yearbook of International Law and European Law

Publication Date: 2020-01-01

Volume: 8

Issue: 1

Page Range: 120-135

Description:

In the aftermath of World War I, Hungary had to relinquish approximately two-thirds of its former territory and over half of its population under the terms of the Trianon Peace Treaty of 4 June 1920. This inevitably brought about a change in the nationality of persons pertaining to territories transferred to other states. However, the interpretation and implementation of articles concerning nationality were highly ambiguous. For example, the rights of citizenship in a commune, the so-called pertinenza, was not defined in the peace treaty, although the determination of affected persons and beneficiaries of the right of option was explicitly based on that particular criterion. Hence, the fate of these individuals largely depended on the domestic legal regulation and the subjective treaty interpretations of successor states. The application of treaty provisions was not always in conformity with the text, which sometimes proved advantageous, other times disadvantageous for the affected persons. This study seeks to explore the theoretical background, the past and present interpretation, the practical application and the judicial treatment of articles concerning nationality in the Trianon Peace Treaty. The paper also exposes the major problems and shortcomings of the Treaty and makes suggestions for an appropriate wording and adequate interpretation of relevant treaty provisions. Furthermore, in order to provide a full picture of how territorial changes following World War I affected the nationality of millions of individuals, the study takes into consideration other contemporary international instruments with a bearing on the change of nationality or its consequences.

Description:

This paper gives aspects related to a cooperation scenario in the framework of multiagent systems. The presentation is focused on a trivial multiagent system that consists of two agents, the Master and the Apprentice. The theoretical basis of the cooperation scenario is the definition of the most probable process, and two algorithms are used with this regard. The formulation of the cooperation scenario is exemplified for a case study that builds an architecture of successively placed bricks in the workspace. © 2011 IEEE.
