Published: September 2022

Study Purpose. This study background is that the performance of the sickle kick in Pencak Silat learning is very important to improve the athlete’s performance during the match, both when attacking and defending. The objective is to analyze the performance of the Pencak Silat sickle kick in terms of the quality of physical conditions (such as leg muscle explosive power and flexibility), and psychological elements (such as achievement motivation).
Materials and methods. This study involved Pencak Silat athletes of Tangan Mas College, Padang, Indonesia. The participants who became the study sample were 30 male athletes aged 14–17 (athletes in the adolescent category). The sample selection was based on the sample criteria providing that participants had participated in regional level competitions and had attended training for at least 2 years. Data were obtained from several tests and measurements: leg muscle explosive power was measured using the Vertical Jump Test and then processed by the Lewis formula (nomogram). Flexibility was measured using the Side Split Test, achievement motivation was assessed using a questionnaire validated by experts, and a sickle kick performance was tested. The data obtained were analyzed using simple regression analysis and multiple regression analysis, followed by path analysis to calculate the coefficient value of each variable.
Results. The data obtained were analyzed using structural model path analysis. Results: (1) there is an effect of leg muscle explosive power on the sickle kick performance by 21.59%; (2) there is an effect of flexibility on the sickle kick performance by 6.94%; (3) there is an effect of achievement motivation on the sickle kick performance by 9.74%; (4) there is an effect of leg muscle explosive power through achievement motivation on the sickle kick performance by 38.14%; (5) there is an effect of flexibility through achievement motivation on the sickle kick performance by 13.51%; and (6) there is a simultaneous effect of these variables by 51,41%.
Conclusions. Based on the analysis of the three factors above, it was concluded that leg muscle explosive power is the dominant factor and needs to be taught and trained seriously. However, the other factors are no less important. Future studies are urgently needed to include other variables that affect the results of this study, as well as a wider number of samples to validate the results of this study.

Published: September 2022

Background. Physical inactivity is associated with poor physical fitness and weight gain. Organized sports activities can be a significant component in providing adequate fitness which, on its part, is an important aspect of general health and well-being. The purpose of the study was to establish the relationship between participation in organized sports activity and obesity as well as physical fitness of 6–10-year-old children from the region of the city of Skopje in the Republic of North Macedonia.
Materials and methods. The height, weight, body mass composition, and various components of physical fitness were measured in 940 children (aged 8.98 ± 3.39). The sports participation and confounding variables, such as parents’ education and body weight as well as parents’ sports activities, were estimated through a questionnaire completed by parents. In order to achieve the study purpose, the study used the multinomial logistic regression analysis and the multivariate analysis of covariance (MANCOVA).
Results. Less-than-once-a-week sports participation was established in 41.1% of the children, once or twice a week – in 48.4%, and more often – in 10.5%. Obesity was established in 38.1% of the children. Children that had organized sports activity 1-2 times a week or more often showed a higher physical fitness level.
Conclusions. Even though causality cannot be established, facilitation of organized sports activities may be a crucial aspect in public health efforts addressing the growing problems associated with overweight and obesity.

Authors: Nemček Dagmar 
Published: September 2022

Study purpose. The study purpose was to investigate gender differences in children’s attitudes toward the inclusion of a student with visual impairment in physical education classes.
Materials and methods. The study sample comprised 419 able-bodied primary school students in 6th to 9th grade (boys, n=204, mean age 13.23±1.17 years; girls, n=215, mean age 13.08±1.19 years). A modified version of the standardized attitudinal questionnaire CAIPE-R for the inclusion of visually impaired (VI) students was used as a research method. The internal reliability of CAIPE-R was measured using Cronbach’s α. The Shapiro-Wilk test was used to assess the normality of sample distribution. The non-parametric Mann-Whitney U-test was used to assess differences between boys and girls, and the Wilcoxon Signed-Rank test assessed differences between general and sport-specific attitudes.
Results. Boys presented rather neutral or indifferent (mean scores 3.19, 3.44 points) attitudes, and girls had slightly positive (mean scores 3.59, 3.74 points) attitudes toward inclusive physical education (PE). Girls, compared to boys, expressed more positive general (U=16786, p=0.000) as well as sport-specific (U=16586, p=0.003) attitudes towards the inclusion of the VI student in PE classes. Both groups of children declared more positive general attitudes than sport-specific attitudes towards the inclusion of VI students (boys, Z=-4.230, p=0.000; girls, Z=-3.015, p=0.003).
Conclusions. Girls expressed more positive general and sport-specific attitudes towards the inclusion of VI students in PE classes than boys. Boys’ attitudes were only neutral or indifferent, and girls’ attitudes were only moderately positive. Both genders declared more positive general attitudes towards the inclusion of VI students in PE classes compared to sport-specific attitudes. Taking into consideration the above, to find the most appropriate solutions as regards the inclusion of students with different kinds of disabilities in PE classes, it is necessary to learn more about the attitudes towards inclusion from students, teachers, and school management.

The field of renewable energies provides solutions to the sustainable energy challenges of developing countries. Various renewable energy options are used to solve the power shortage in India. In recent years, power generation has increased significantly, but the market is promising for domestic organisations, distribution networks and transmission networks, and the financial situation is sluggish and influential. India has 450,000 kilowatts of hydroelectric power, has an installed wind power capacity of 230,000 kilowatts, but has almost no great potential for renewable energy. However, India is currently very high in this region, 2022 (not including large hydropower), the target is to raise the current installed capacity from 37 GW of renewable energy to 1.75 million kilowatts. Solar energy is a key part of the government’s extension policy. The demonstration of solar PV Systems is highly advantageous for geography and structure. For efficient structure, we need effective design and forecasting tools. PV system is a popular tool to optimise and schedule the design and construction of independent photovoltaic solar systems connected to the grid.
The objective of this research is to introduce the equivalent design model of the photo voltaic solar power plant and to analyses the impact of power forecasting on performance assessment of solar photo voltaic system. Mathematical model of solar photovoltaic system has been implemented using and performance is analysed using PV and IV characteristics of solar photovoltaic system. Modified prediction technique was implemented for optimum forecasting in the specified scenario of complex operating condition.

Published: September 2022

Code Division Multiple Access (CDMA) and Orthogonal Frequency Division Multiplexing are two multicarrier regulatory systems that have improved due to the growing demand in quick communication (OFDM). A frequency division multiplexing (FDM) plot called orthogonal frequency division multiplexing is utilized as a sophisticated multi carrier regulation approach.
Due to its excellent spectrum efficiency and low data rate, the single carrier multiple access system (SC-FDMA) is a unique radio transmission technique that is now employed in long-term evolution (LTE) technology for uplink. When compared to OFDM, reduced peak-to-average power ratio (PAPR) and error rate technique. PAPR performance has been obtained using Matlab simulation. Techniques using variable numbers of subcarriers include SC-FDMA and OFDMA. Two various subcarrier assignment strategies have been proposed, distributed FDMA Localized FDMA and (DFDMA) (LFDMA). IFDMA, or interleaved FDMA, is a DFDMA special situation when DFT results have been distributed consistently and at the same distance. When comparing the SC-FDMA variants, we discover that Localized has a higher PAPR than interleaved (FDMA) (FDMA). We also talk about the Performance of LFDMA and IFDMA's SER (Symbol Error Rate) and found that localized (FDMA) performs better in the SER than interleaved (IFDMA) method.
Competition law: through restrictions to freedom
Authors: Seregin D. I. 
Published: September 2022

The author is critical of the understanding of competition law as an industry that restricts entrepreneurial activity. On the contrary, the article shows that the absence of competition law as a complex system of legal norms leads to a restriction of entrepreneurial freedom — monopolization and cartelization of the economy.The author wonders why the protection of competition required the use of legal means, and did not remain the lot of economic policy? What is the meaning of the formation of competition law as a complex system that ensures the effectiveness of the market economy?In search of an answer to these questions, the author comes to the conclusion that the law regulates antimonopoly policy, makes it understandable and predictable for all participants in civil turnover. However, the analysis of the essence of law carried out by the author allowed us to come to additional conclusions showing that competition law, by setting limits on the freedom of subjects of regulated relations, is a system of norms aimed at ensuring the freedom of market participants.

Namen: Tuberozna skleroza je avtosomno dominantni nevrokutani sindrom, ki prizadene približno 1/6.000–10.000 ljudi. Klinična slika se s starostjo spreminja, saj so pri različnih starostih prisotni različni klinični znaki. Ledvična prizadetost je prisotna pri 48–80 %, in sicer v obliki angiomiolipomov, ledvičnih cist ali ledvičnega karcinoma. Namen naše raziskave je bil pregled kliničnih manifestacij pri bolnikih s tuberozno sklerozo, obravnavanih znotraj Univerzitetnega kliničnega centra (UKC) Maribor v zadnjih desetih letih, in opredelitev števila tistih, ki imajo ledvično prizadetost.Metode: Pregledali smo kartoteke bolnikov, ki so vodeni v UKC Maribor z diagnozo tuberozna skleroza (MKB– Q85.1). Iz medicinskih zapisov smo razbrali njihove antropometrične meritve, starost ob diagnozi, laboratorijske izvide, slikovne preiskave in morebitne rezultate genetskega testiranja ter trenutni režim zdravljenja. Rezultati: V naši kohorti je 13 bolnikov s tuberozno sklerozo, starih od 7 do 71 let, mediana starost je 16 let, povprečje 25,2 (14,6; 35,9). 92 % (12) ima kožno simptomatiko, ledvična prizadetost je prisotna pri 60 % naših bolnikov. 46 % ima angiomiolipome, 23 % ledvične ciste. Pomembnejše prizadetosti ledvične funkcije nimajo. Sistemsko terapijo z everolimusom prejemata dva bolnika, dva imata predpisan topični everolimus za kožne lezije. Genetsko testiranje je bilo opravljeno pri 7 bolnikih, pri 5 je bilo pozitivno.Zaključek: Rezultati potrjujejo pogosto prizadetost ledvic pri bolnikih s tuberozno sklerozo v naši kohorti, primerljivo z literaturo. Ker je kohorta sestavljena predvsem iz pediatričnih bolnikov, je ledvična funkcija dobra, zdravljenje pa redko nujno. Redno spremljanje in multidisciplinarna obravnava sta ključna za dolgoročno blaginjo bolnikov.

Namen: Objektivni strukturirani klinični izpit (OSKI) je postal vodilna metoda za ocenjevanje izvedbe kliničnih veščin. Njegova pogosta težava je neskladje med oceno na ocenjevalnem obrazcu in splošno oceno ocenjevalca. V preteklosti neskladij niso uspešno reševali z obteževanjem posameznih korakov. Sistematičnega diferencialnega obteževanja, ki podeljuje točke glede na izračun časovnih in težavnostnih uteži, še niso raziskali. Namen študije je bil: a) tvoriti formule za izračun težavnostnih in časovnih uteži, b) tvoriti eksperimentalni obrazec z upoštevanjem izračunanih uteži in c) oceniti uspešnost metode pri izboljšanju kazalnikov kakovosti OSKI.
Metode: Najprej smo tvorili formule za izračun časovnih in težavnostih uteži posameznih korakov. Nato smo s pomočjo uteži obtežili posamezni korak v eksperimentalnem obrazcu. Kontrolni obrazec so neodvisno od raziskave obtežili klinični mentorji. Uspešnost obrazcev smo preverili med rednim izpitom OSKI za študente 3. letnika. Študente (n = 55) je z obema ocenjevalnima obrazcema in splošnim obrazcem ocenilo deset ocenjevalcev. Rezultate smo analizirali s t-testom za odvisna vzorca, enostavno linearno regresijo in psihometričnim testiranjem.
Rezultati: V primerjavi s kontrolnim obrazcem smo na eksperimentalnem obrazcu ugotovili višjo povezavo med oceno na ocenjevalnem obrazcu in splošno oceno (r = 0,622, p < 0,001 vs. r = 0,496, p < 0,001) in pomembno nižje rezultate (p < 0,001).
Zaključek: Ugotovili smo, da diferencialno obteževanje korakov s časovnimi in težavnostnimi utežmi lahko izboljša kazalnike kakovosti OSKI in zmanjša neskladje med oceno na ocenjevalnem obrazcu in splošno oceno.

Namen: Rak debelega črevesa in danke (RDČD) je v svetovnem merilu tretja najpogostejša maligna bolezen in najpogosteje zaseva v jetra. Namen raziskave je predstaviti možnosti kirurškega zdravljenja jetrnih zasevkov in rezultate zdravljenja.
Metode: Opravili smo retrospektivni pregled prospektivno vodene datoteke resekcij jetrnih zasevkov RDČD na Kliničnem oddelku za abdominalno in splošno kirurgijo Univerzitetnega kliničnega centra Maribor. Raziskava temelji na principu pristopa k zdravljenju z namenom ozdravitve. Analizirali smo število posegov, ponovne posege, zaplete in preživetje.
Rezultati: Od januarja 2000 do decembra 2020 je bilo izvedenih 631 kirurških posegov zaradi jetrnih zasevkov RDČD. 352 (74,4 %) bolnikov je bolnikov več kot enega. Resekcij jeter je bilo 541 (85,7 %), in sicer 389 manjših in 152 velikih resekcij. Radiofrekvenčno ablacijo smo opravili v 61 (9,7 %) in eksploracijo v 29 (4,6 %) primerih. Ponovnih posegov je bilo 138 (21,9 %). Hudi zapleti (stopnja ≥ 3a po klasifikaciji Clavien-Dindo) so se pojavili po 84 (13,3 %) posegih. 90-dnevna pooperativna smrtnost je znašala 3,8 %. Mediano preživetje pri seštevku 0 v Clinical Risk Score je 69 mesecev; 5- in 10-letni preživetji sta 57-% oziroma 38-%.
Zaključek: Kirurška odstranitev jetrnih zasevkov v celoti in ugodni prognostični dejavniki omogočajo dolgoročno preživetje bolnikov z jetrnimi zasevki RDČD.

Namen: Namen prispevka je predstaviti možnost poravnave zob z estetskimi prozornimi opornicami, ki jo omogoča tehnologija, v celoti izvedena v Sloveniji.
Poročilo o primeru: 34-letni pacient je obiskal specialistično ambulanto zaradi nepravilnega položaja zob v spodnji čeljustnici. Cilj zdravljenja je bil poravnati zobe v spodnjem zobnem loku z uporabo prozornih opornic, izdelanih v Sloveniji. Postopek smo začeli s kakovostnim odtisom za delovni model. Delovni model smo skenirali in tako v računalniku ustvarili 3D različico pacientovih zobnih lokov in griza. S pomočjo programske opreme smo izdelali 3D navidezni model in na njem zobe premaknili v želen (optimalen) položaj, ki naj bi ga dosegli z opornicami. Opornice smo izdelali iz termoplastičnega materiala (poliuretan) s termo-formiranjem, in sicer s pomočjo modela, izdelanega z laserskim sintranjem. Pacient je prejel navodila o 22-urni dnevni nošnji, vsako opornico zamenja po 2 tednih. Obravnava je trajala 6 mesecev. Ob koncu zdravljenja je bil nameščen fiksni retencijski lok za stabilizacijo in preprečitev recidiva. Pacient je z rezultatom bil zelo zadovoljen. Dve leti po zaključenem zdravljenju stanje ostaja nespremenjeno in stabilno.
Zaključek: Zdravljenje s prozornimi opornicami je v primerjavi s klasičnimi fiksnimi aparati snemljiva tehnika, ki zagotavlja boljšo estetiko, večje udobje, omogoča boljše vzdrževanje higiene.
