On the Efficiency of the Lamport Signature Scheme
Authors: Zentai Daniel 
Published: October 2020

Abstract
Post-quantum (or quantum-resistant) cryptography refers to a set of cryptographic algorithms that are thought to remain secure even in the world of quantum computers. These algorithms are usually considered to be inefficient because of their big keys, or their running time. However, if quantum computers became a reality, security professionals will not have any other choice, but to use these algorithms. Lamport signature is a hash based one-time digital signature algorithm that is thought to be quantum-resistant. In this paper we will describe some simulation results related to the efficiency of the Lamport signature.

Abstract

Introduction
Specific correlations among diffusion tensor imaging (DTI)-derived metrics and magnetic resonance spectroscopy (MRS) metabolite ratios in brains with glioblastoma are still not completely understood.

Patients and methods
We made retrospective cohort study. MRS ratios (choline-to-N-acetyl aspartate [Cho/NAA], lipids and lactate to creatine [LL/Cr], and myo-inositol/creatine [mI/Cr]) were correlated with eleven DTI biomarkers: mean diffusivity (MD), fractional anisotropy (FA), pure isotropic diffusion (p), pure anisotropic diffusion (q), the total magnitude of the diffusion tensor (L), linear tensor (Cl), planar tensor (Cp), spherical tensor (Cs), relative anisotropy (RA), axial diffusivity (AD) and radial diffusivity (RD) at the same regions: enhanced rim, peritumoral oedema and normal-appearing white matter. Correlational analyses of 546 MRS and DTI measurements used Spearman coefficient.

Results
At the enhancing rim we found four significant correlations: FA ⇔ LL/Cr, Rs = -.364, p = .034; Cp ⇔ LL/Cr, Rs = .362, p = .035; q ⇔ LL/Cr, Rs = -.349, p = .035; RA ⇔ LL/Cr, Rs = -.357, p = .038. Another ten pairs of significant correlations were found in the peritumoral edema: AD ⇔ LL/Cr, AD ⇔ mI/Cr, MD ⇔ LL/Cr, MD ⇔ mI/Cr, p ⇔ LL/Cr, p ⇔ mI/ Cr, RD ⇔ mI/Cr, RD ⇔ mI/Cr, L ⇔ LL/Cr, L ⇔ mI/Cr.

Conclusions
DTI and MRS biomarkers answer different questions; peritumoral oedema represents the biggest challenge with at least ten significant correlations between DTI and MRS that need additional studies. The fact that DTI and MRS measures are not specific of one histologic type of tumour broadens their application to a wider variety of intracranial pathologies.
Source Model of Domestic Gas Stoves
Authors: Leitner Anita Vörösné , Kajtár László 
Published: October 2020

Abstract
Results from medical research show that the use of domestic gas stoves could have a major impact on human health and well-being, especially if they used for heating. Approximately 0.289 m3 of natural gas is combusted daily in Hungarian kitchens. The users normally stand near the stove during its operation, which on average is 45 minutes long; therefore, they are directly affected by the combustion products. Nevertheless, uncertainties remain concerning the effects of the combustion products on humans; the nitrogen dioxide load could be the most problematic. Its nominal source strength is in a range of 12.0 - 21.0 ug/kJ, depending on the type of burner. In order to improve kitchen ventilation, a source model of domestic gas stoves has been developed that is based on measurement results, statistical data, and further technical assumptions.

Published: October 2020

Abstract
In this paper, we have developed an efficient hybrid meta-heuristic algorithm for structural cost optimization of a waffle slab and have also solved the relevant optimization problems. The cost of the waffle slab is considered to be the objective function, and the design is based on the American Concrete Institute’s ACI 318-08 standard. This algorithm utilizes the recently developed mouth-brooding fish (MBF) algorithm as the main engine and uses the favorable properties of the colliding bodies optimization (CBO) algorithm. The performance of this algorithm is compared with MBF, CBO, harmony search (HS), particle swarm optimization (PSO), democratic particle swarm optimization (DPSO), charged system search (CSS) and enhanced charged system search (ECSS). The numerical results demonstrate that the proposed algorithm can construct promising results and has merits in solving challenging optimization problems.

Authors: Sobkowiak Paweł 
Published: October 2020

Abstract
Cultural intelligence (CQ) as a micro-level construct describing intercultural competence has garnered growing attention in academic literature recently, resulting in an increase in research. This paper reports on the empirical research which, using as a survey instrument the Cultural Intelligence Scale (CQS) developed by Earley and Ang (2003), examined intercultural competencies of Polish EFL students at the tertiary education, measured by the level of CQ. In addition, the investigation aimed to analyze whether individual difference variables such as gender, educational level, linguistic proficiency, multilingualism, motivation to study English, and study abroad experience are significant predictors of students’ level of CQ. The results show that the respondents’ intercultural competence has been developed only to a small degree. Further, CQ is positively related to gender, educational level, foreign language proficiency, the number of foreign languages known, motivation to study English, and study abroad experience. Some practical applications of the study findings for the Polish tertiary education have been presented.

Vegetation Indices is one of the remote sensing parameters that can be used to estimate the mangrove forest density. The purpose of this study is to determine the vegetation index with the best accuracy to estimate the condition of mangrove density, as well as determine the spatial distribution of mangrove density in the TNBB area. This study uses Sentinel-2A satellite imagery data and five different vegetation indices, namely NDVI, NNIR, EVI, mRE-SR, and vegetation index developed in this study. The method of determining samples in the field uses stratified random and proportional sampling. Data collection of canopy density used hemispherical photography method, which is taking vertical photos with a 180o angle of view using a camera with a Fish Eye or Wide lens. Data analysis used in this study is regression analysis, coefficient of determination test, model validation test, and paired t test. From statistical tests conducted on several vegetation indices, the mRE-SR vegetation index value shows the best results on all the accuracy parameters tested. The R2 value was generated by the mRE-SR vegetation index from the relationship between mangrove density results from field measurements with the vegetation index value and the estimated density results shows that the highest values, namely 0.909 and 0.935. These results show that the mRE-SR vegetation index is the best vegetation index in explaining the variation of mangrove density in the field. The mRE-SR vegetation index also has the lowest deviation of the estimated value, with the resulting SE values in the two linear relationships of 1,592 and 0,999. In addition, the mRE-SR vegetation index has a P (T <= t) two-tail value greater than the significance level (0.05), the results means that two values of the tested variables are not significant different. The calculation results show that the total area of mangroves in TNBB is 409.21 ha. From the percentage of density obtained, the mangrove density class was only distributed in the medium and solid density classes.

Nusa Penida is a tourist destination, located on the east of Bali, which is well-known of its natural panoramic. Increasing tourism sector in Nusa Penida may have positive impacts, but it can also have negative impacts, such as an increase in the amount of waste and other pollutants, which will eventually be discharged into the waters. High concentration of pollutant can reduce water quality. The water quality in the sea can be control by the residence time, and the sea current would spread waste in the ocean. Based on these problems, it is important to conduct a research on the movement and length of particle residence in the waters of Nusa Penida, Bali. This research was carried out in January 2019, to represent the rainy season conditions, and in July 2019, to represent the dry season conditions. The residence time was calculated using a numerical modeling method namely Finite Volume Coastal Ocean Model (FVCOM). Based on the simulation results, the residence time of particle in the dry and rainy season has a similar pattern. Areas with fast residence times are found in the eastern Nusa Penida waters, while areas with weak residence times are found in the Toyapakeh strait. Generally, Nusa Penida waters have a relatively short residence time, 1- 4 hours.

Objectives. To assess the advantages and disadvantages of videolaryngoscopy as one of methods of tracheal intubation which is being widely used as an alternative to direct laryngoscopy in anesthesiologist’s practice.Material and methods. Over 100 of tracheal intubations were conducted with the use of videolaryngoscope, along with a routine use of the direct laryngoscopy. The results of 48 intubations are discussed. 4 clinical cases are presented in this article.Results. Cormack-Lehane grade I view was obtained in 39 cases (81,3%), Cormack-Lehane grade II - in 9 patients (18,8%). First attempt intubation was performed in 43 cases (89,6%), in 4 cases intubation was successful after second attempt (8,3%), failed intubation was in 1 case (2,1%). The mean duration of successful intubation was 36,9 sec. Certain difficulties occured during intubation related with the advancement of the endotracheal tube. Technical solutions are given for some of intraprocedural conditions.Conclusions. Videolaryngoscopy is a safe and effective method of tracheal intubation. Although this method is not lacking in disadvantages it has a number of advantages, main of which is the improved larynx visualization. In our opinion, this method can not completely replace direct laryngoscopy in anesthesiolodist’s practice, but may serve as an adjuvant in case of difficult intubation.

Tujuan penelitian ini adalah untuk mengetahui, mendeskripsikan, dan menganalisa persepsi masyarakat perihal kesejahteraan sosial yang secara tanpa sadar memengaruhi perilaku dan sikap hidup dalam hidup bermasyarakat dan bernegara. Perspektif dialektis menjadi objek formal penelitian ini. Penelitian ini menggunakan metode kualitatif. Teknik pengumpulan data dilakukan melalui kajian pustaka. Data yang telah dikumpulkan, diklasifikasikan untuk mendapatkan data dominan, untuk dianalisis. Peneliti menganalisis data dengan cara disajikan, direduksi, dideskripsikan, dan dievaluasi. Peneliti merefleksikan dan menganalisis untuk memboboti secara kritis dari perspektif peneliti untuk kemudian disimpulkan. Hasil penelitian ini menginformasikan bahwa kesejahteraan sosial tidak hanya terkait dengan pemenuhan barang, jasa, kepastian hukum untuk keseimbangan dan kenyamanan, serta kepentingan individu semata, melainkan sebuah kesejahteraan yang berorientasi pada kesejahteraan umum dan kebaikan bersama (communal well-being & bonum communio). Perspektif diaklektis kesejahteraan adalah kolaborasi hak dan kewajiban secara proporsional antara ayah-ibu-anak atau masyarakat-pemerintah-negara. Kesejahteraan membutuhkan perbaikan positif untuk penciptaan peradaban baru sebagai sintesis dan bukan repetisi. Gerakan kesejahteraan bersifat altruistik dan bukan egoistik-individualistik. Kesejahteraan menuntut pemberdayaan, maksimalisasi kinerja, peningkatan etos kerja sebagai bagian dari pengungkapan identitas dan hakekat manusia sebagai "homo vaber" atau “animal rationale”.

Published: October 2020

A field study was conducted on ‘enset’ propagation at Humbo, Wolayta. The experiments of this study were executed with the objectives of determining size of whole corms and corm pieces for better sucker production. Five whole corm sizes (0.75, 3, 7, 11and15 kg), five bigger (0.8, 1.75, 2.3, 3.5 and 4.6) and three smaller (0.2, 0.3 and 0.4 kg) corm pieces, three corm piece positions (lower, middle and top) of horizontal cut. There were significant (p<0.01) differences among corms and corm pieces in the number of suckers. Whole corms with 7 kg gave the highest number of suckers; similarly, corm pieces with 3.5 kg. The mean number of suckers produced ranged from 9.5-28.4 for whole corms, 3.7-38.1 for corm piece. There was no positive and significant relationship between total number of suckers and growth. Many of the other growth parameters are associated with each other. The highest sucker number was recorded using corms of 7 kg corm and 3.5 kg corm pieces. Significant variations among corms and corm pieces in the number of suckers formed, with whole corms, corms with 7 and 3 kg weights scored the highest number of suckers. With corm pieces, those with 3.5, 4.6, and1.75 kg sizes scored the highest sucker numbers. Compared for whole corms, corm pieces gave the greatest overall number of suckers. The size of corms and corm pieces had a significant effect on leaf width and leaf length; and sucker height, pseudostem length leaf width, leaf length and leaf number respectively. The position of the corm from which pieces were taken affected their regeneration capacity. Corm pieces from the apical end of the corm were able to regenerate.

During camping in BNCC all cadets face some medical problems. Their problems not more worsen but this may lead misunderstanding about the training of BNCC. Our cadets are normally fit because when they get admitted in BNCC there was a criterion that they are medically fit or not. The major problems such as asthma, big birth defect, nasal and ear problems not allowed in BNCC. In camping they get excellent medical services so that they not fall serious problems. In BNCC camping cadets get always fresh food and water and moreover they take bathe regularly. After march past or exercise they take oral saline, so not shown any dehydration. Some simple injuries for wearing tight shoes and for crawling knee and elbow injury are common. All trainings are held in winter season so for cold weather their exercise not considered burden. Cadets sweating are very few so they get more energy in training. In noon they perform playing and every night the cultural show rehearsal runs. Mostly all cadets live well any camping without any major diseases. The writers of this paper both they attend several camping with high ages but not got any major diseases during camping (Plate 4).

Background. The most rational way to reduce barley crop losses from diseases, pests and adverse edaphic factors is cultivation of resistant varieties. The specificity of the host– pathogen interactions necessitates a constant search for new donors of resistance for breeding, and phytosanitary monitoring of cultivars.Materials and methods. The research material comprised 248 barley cultivars included in the State Register of Selection Achievements Admitted for Usage in the Russian Federation – 168 were developed domestically, and 80 by foreign breeders. Their resistance to powdery mildew and leaf rust was studied in under laboratory and field conditions. Barley cultivars distinguished for powdery mildew resistance were analyzed using molecular markers. In the laboratory, barley was screened for greenbug resistance. To study the sensitivity to toxic aluminum ions in barley, we used the laboratory method for the early diagnosis of the trait – the root test method.Results and conclusions. Field and laboratory screening revealed a fairly wide diversity of barley cultivated in Russia in terms of resistance to harmful organisms and the edaphic stressor. It was established that 24 barley cultivars were resistant to powdery mildew, and 14 accessions were carriers of the effective mlo11 allele. Two cultivars manifested combined resistance to powdery mildew and barley leaf rust. In 11 cultivars, a distinct greenbug resistance was revealed. High resistance to toxic aluminum ions according to the root and sprout length indices was observed in 26 cultivars. Accessions with the complex resistance to harmful organisms and the edaphic stressor were identified.
