Spineline detection with image evaluation

In case of screening and tracking conditions of patients [20] with spinal deformities it is very important to develop an examination method that does not load patinets’ body with harmful radiation. This method is based on the moiré effect. Pictures were taken from patients’ back and information could be obtained about the back’s condition. A computer algorithm is under development that can produce the sagittal line of the spine from moiré images. This program is being tested with Scheuermann disease patients

Defining of the Shape of the Spine Using Moiré Method in Case of Patients with Scheuermann Disease

Nowadays spinal deformities are very frequent problems among teenagers. Scheuermann disease is a one dimensional deformity of the spine, but it has prevalence over 11% of the children. A traditional technology, the moiré method was used by us for screening and diagnosing this type of spinal deformity. A LabVIEW program has been developed to evaluate the moiré pictures of patients with Scheuermann disease. Two different solutions were tested in this computer program, the extreme and the inflexion point calculation methods. Effects using these methods were compared and according to the results both solutions seemed to be appropriate. Statistical results showed better efficiency in case of the extreme search method where the average difference was only 6,09⁰

Colour of Stone Slabs under Different Standard Illuminations

Spectral measurements have been carried out on polished stone slabs to show the accuracy of theoretical colorimetric calculations on perceptual differences of color appearance under various standard illuminations. Effects of the different spectral characteristics of the light source on colorization of the samples have been also studied to analyze the changes of color sensation on the samples in connection with the changes on the type of the illuminating source. Solar light (Standard Illuminant D65), basic incandescent source (Standard Illuminant A) and a basic fluorescent source (Standard Illuminant F11) have been tested on Tardos red limestone, Siklós green limestone, Carrara white and gray marbles and diorite samples. Colorizing effects of the examined illuminations are compared to Standard Illuminant E – the theoretically perfect white source

Digitális moiré képek vizsgálata gerincferdüléses betegek nyomon követésére

A gerincferdüléses gyermekek konzervatív kezelésének eszköze a korzett, mely egy kemény PE „páncél”, ami a gerinc helyes állását nyomófelületeken átadott nyomóerő közvetítésével éri el. A Salus Ortopédtechnika Kft.-nél a korzettet viselőgyermekek állapotváltozásának diagnosztizálására évek óta használnak moiré berendezést. A rendszerhez kapcsolódó mérési módszer általános használatbavételéhez elengedhetetlen a hitelesítés. A hitelesítés a moiré rendszerrel meghatározott Cobb fokok és az általánosan elfogadott, kétirányú, álló helyzetben készített röntgenfelvételeken meghatározható Cobb fokok összehasonlításával történhet. 19 páciens – 9 és 17 év közötti scoliosissal és Scheuermann-betegséggel kezelt gyermek – 49 moiré felvétele alapján készült a kiértékelés. Az eredmények alapján látható, hogy a módszer a gerincferdülés követésére jól alkalmazható, de röntgenfelvételeken meghatározott szögértékekhez képest a moiré felvételeken meghatározott értékek jelentősen (akár 10–15°-kal) kisebbek lehetnek, különösen a felsőháti és az ágyéki görbületek esetén, ahol statisztikai úton is szignifikáns eltérés igazolódott a két módszer eredményei között. Ez okot adhat arra, hogy elgondolkodjunk az értékelési algoritmus alaposabb elemzésén és pontosításán, melyet a későbbiekben tervezünk elvégezni. DOI: 10.17489/biohun/2014/1/0

Technological innovation at Salus Ortopédtechnika Kft. Regarding the GERINCOR project

In this article we tried to introduce our renewed technology regarding the Gerincor project. Instead of the old technology the new provides much cleaner, more accurate, and more comfortable procedure for our young patients. Moreover data could be archived much easier.  DOI: 10.17489/biohun/2013/1/1

Azonosságok és különbségek - Munkaattitűdök és a munkával való elégedettség jellemzői 2005-2018 között

In our study, we present the domestic aspects of work-related attitudes, focusing on the period after the turn of the millennium. In our analytical work, we aimed to examine the characteristics of job satisfaction, work-related attitudes, and work-related stress in a database of two national and one county seat. In our writing, in addition to the descriptive analysis of the three databases, we focus on exploring possible changes and differences in time and space. According to our results, the job satisfaction of the respondents of the two national surveys shows almost the same pattern, while the opinion of the local society shows a different and more unfavorable picture. This can be explained, among other things, by the fact that our local survey took place in one of the most disadvantaged counties of the country, Szabolcs-Szatmár-Bereg county. In addition, it should be emphasized that the location of our research, as the county seat, still has more favorable conditions than other settlements in its agglomeration. The other two national databases that form the basis of the analysis were created within the framework of the International Social Survey Program. Based on Herzberg's two-factor model, we can conclude that certain factors belonging to the group of external motivations, such as favorable earnings, job security are equally important for all groups of respondents. This is consistent with the terminology of work as a core value for livelihood. According to the national sample conducted in 2005, the internal motivational factors, such as the interest and usefulness of the work, and the importance of the work that can be done independently were the most decisive. The opinions of the 2015 national and 2018 local respondents were nearly the same in this respect. Overall, it can be stated that both the differences and the similarities characterize the job satisfaction, work attitude and work-related stress situation of the respondents of the three survey years. The issue of divergence and convergence is shaped not only by regional characteristics, but also by social and economic processes and the social and individual responses to them
