Authors: Lv Ting , Lu Yehu , Zhu Guoqing
Published: August 2022

Following the principle of “people-oriented”, we explore the user needs of smart clothing for the elderly and provide reference for the development of such clothing. The target consumers of smart clothing for the elderly are divided into two categories: The elderly and the young, and the needs of elderly users are investigated by means of literature analysis and interviews. The study showed that the needs of elderly users for senior smart clothing can be divided into five areas: Physiological, psychological, aesthetic, functional and consumer; the younger group is generally willing to buy senior smart clothing for the elderly and wants functional design to focus on physiological monitoring technology and aesthetic design to focus on loose fit design and dark shades of colour matching. The findings of the study will help companies to improve their design solutions and promote the healthy development of the senior clothing market.

MENGÜ ERTEL'S DESIGN STYLE (SAMPLE OF POSTER DESIGNS)
Authors: GÖKALAN Merve , SEVİNDİK Orhan
Published: August 2022

The art of graphic design, which emerged in the establishment phase of the Republic and developed with the effective support of master artists, started to blossom through successful works. In the field of graphic design, the first unforgettable name that comes to mind as a Republican era artist is İhap Hulusi Görey. Another graphic designer, Mengü Ertel, who, like Görey, has made a name for himself in Turkey with his designs -especially theatrical poster designs-, has followed the western design language since the Academy of Fine Arts. Although he considered the original stance of Polish posters as close to his own design language, it is visible in the designs he made that he has captured a unique style in poster designs and became original over time. This research aims to analyze the Ertel-specific style in the posters designed by Mengü Ertel, taking into account the design approaches of the period. The research seeks to answer the following question: “How is the style in the poster designs of Mengü Ertel?” In this context, Ertel's poster designs were examined using the "content analysis" technique, which is based on the survey model. In the research, 103 posters designed by Mengü Ertel were analyzed. The findings show that unique patterns are at the forefront in Mengü Ertel's design style, and the typographic elements he used not only provide information, but are also actively used as design objects. It is identified that there was a color palette that was reflected in all posters, especially in selecting the colors. When the poster designs prepared by Mengü Ertel were examined, the economic desperation experienced did not prevent the artist from being successful in his designs, and he concentrated his love and curiosity for the art of theater on the axis of poster designs and created original designs. In addition, the research has set as a side goal of creating knowledge about a crucial graphic designer in Turkey by contributing to the very few academic studies about Mengü Ertel.

Now Ci’literature(詞文學) of Chinese lose one’s musicality. But, we can’t understand the tune, it is also worthwhile to consider only the lyrics. It’s only the lyrics, but it’s the most emotional literature in China.
Ci’literature started with a Huajian’Ci(花間詞). And, from this on, it was developed without any hesitation by mass-producing various aspects. But, while overlooking Ci’s habitually separates it into a lake wave(婉約派) and a complete wave(豪放派). Dichotomy is not systematic and less persuasive. The attitude to reveal Ci’literature with a lake wave and a complete wave is vague and far-fetched.
To understand Tang&Song’Ci(唐宋詞) well, we must accurately understand the formation of the wave and its organic relationship. For this, this study started to solve the problem and the formation of the wave.
This will be an opportunity to provide a reasonable clue to the error that simply separates Tang&Song’Ci into a lake wave and a complete wave. In addition, it will be an opportunity to urge scholars who study Ci’literature to continue to collaborate.

Tuberculosis is a communicable infectious disease in majority caused by bacillus Mycobacterium tuberculosis. Lungs are the most often targeted body tissue where infection can spread. Although lung tuberculosis is well curable by combinations of antituberculotic drugs, more serious drug-resistant forms occur. WHO Global Tuberculosis Report provides information about almost half million of new resistant cases and rising multidrug resistant tuberculosis (MDR-TB) together with serious extensively drug resistant tuberculosis (XDR-TB). Resistant species increase cost of hospitalization and prolong length of stay in hospital. Combination of pharmacological and surgical (non-pharmacological) treatment strategy brings successful tuberculosis cure to certain group of patients. Adequate preoperative optimalization and interdisciplinary approach are essential points of effectual surgical care in combination with pharmacological treatment.

Summary: Physical activity is especially important during childhood and adolescence. As part of the support of health and physical activity in Slovakia, data on the physical activity of pupils of selected primary schools were collected within the framework of the National Action Plan for the Support of Physical Activity for the years 2017 - 2020. Material and methods: Data collection took place in the whole territory of Slovakia in the months of March - June 2019 using the questionnaire method through the professionals of the departments of health support and health education in regional public health institutes in the Slovak Republic. A structured questionnaire focused on basic lifestyle analysis (questions on well-being, health, physical activity, nutrition and drinking regime, substance and non-substance addictions) was used as a research method. Excel was used to insert and process the answers obtained by the respondents from the questionnaires. Results: The highest share of respondents rated their physical condition as average (51.2%). 23.4% of respondents stated above-average condition. The majority of respondents reported performing various physical activities daily or almost daily (35.9%) and 3-5 times a week (31.6%). The average duration of their physical activities from 1 hour to 2 hours was stated by 40.1% of respondents. The highest share of respondents (35.5%) stated shortness of breath and weak sweating as the intensity of their physical activities. 44.1% of respondents were registered athletes, 47.4% stated recreational sports in their free time and 8.5% of respondents did not play sports. Conclusion: Most pupils in the 8th grade of the monitored primary schools engaged in some form of physical activity. They engage in physical activity as registered athletes or as part of their leisure activities. Promoting physical activity among children and adolescents thus continues to play an important role in promoting a healthy lifestyle.

Students' computer-based workshops in mandatory classes of English for students majoring in psychology and linguistics: A comparative experimental study
Authors: Volkova Nataliia , Tarnopolsky Oleg , Lebid Olha , Vlasenko Kateryna
Published: August 2022

This article addresses the issue of developing and using students’ workshops in English. In the article, such workshops are defined as the fullest form of peer-teaching in which one or several students (workshop organizers) guide their group-mates in performing extra-linguistic learning activities conducted in the target language. The research describes workshops as one of the most efficient ways of involuntary (subconscious) target language acquisition achieved through extra-linguistic practical (experiential) activities performed by way of communication in the language to be learned. The article reports the results of a comparative experimental study in which students of a non-linguistic major (Psychology) and students majoring in English as a foreign language on which their career option (Applied Linguistics) is based were practicing workshops in English in their mandatory classes on that language. The results of the experimental study clearly demonstrate and prove that workshop practice was quite successful in both cases not only in what concerns the involuntary (subconscious) development of learners’ target language communication skills. No less evident was the development of some of the students’ psychological qualities (emotional intelligence) important for their further studies and professional careers.

Published: August 2022

The effects of temperature on development of Myzus persicae (Sulzer) was investigated at five constant temperature 17, 20, 23, 26 and 29 ± 1 °C, 65 ± 5 % RH, and a photoperiod of 16:8 (L:D) hr fed on cabbage (Brassicae olerasia var. capitata) under laboratory condition using the age-stage, two-sex lifetable approach. The intrinsic rate of increase (r) of this aphid was highest at 29°C (0.3212 d-1) and lowest at 17°C (0.0.2157 d-1). The developmental rate of nymphs at different temperatures fit the linear equation, y= 0.005 x -0.001 with a coefficient of determination (R2) of 0.98. The thermal summation of the pre-adult, the female, and the total life stages (from birth to death) was 194.6, 241.8 and 430.2 DD, respectively. The developmental threshold of the pre-adult, the female, and the total life stage was 0.29, 10.6, and 5.29°C, respectively. The mean generation time was 18 d at 17°C, which declined to 10.2 d at 29°C. The net reproduction rate (R0) was 26.6 offspring/ individual at 29°C, and it was considerably lower than the rates obtained at other temperatures. The highest net reproductive rate was obtained at 20°C (R0= 54.2 offspring/ individual). In the absence of other limiting factors, populations of M. persicae would be expected to increase faster if introduced into environments having temperature ranging between 23 and 26 °C.

The fall army worm (FAW) Spodoptera frugiperda is now spread all over India and at present, spraying insecticides is the primary method of control. Considering its presence in whorl and negative impact of insecticidal spray on the natural enemies, there is a need of evolving alternate techniques. In the present study, whorl application of insecticides mixed in river sand was evaluated for its efficacy. Sand mixed with chlorantraniliprole 18.5SC @0.4 ml/ kg, emamectin benzoate 5SG@ 0.4 g/ kg and spinosad 45SC @ 0.4 ml/ kg sand were found to be effective, with significant reduction in leaf damage. The quantity of insecticide required/ unit area was 50% less than the spray while maximum grain yield/ cost benefit ratio was obtained.

Published: August 2022

An experiment was conducted to evaluate two deterrents to deter blue bull Boselaphus tragocamelus and monkey Rhesus macaque from crop fields through randomized block design experimental trials in different parts of Nepal from July 2019 to May 2021. The odour deterrent tri methyl amine @15ml/ 700 m2 and microbial fermented fish solution @4ml/ l were evaluated among 150 plots each with 50 replications including control. Significant results were obtained where >90% farmers responded that tri methyl amine repelled blue bull and monkey for >14 days. This might be due to its strong ammonia like fishy odour which was unpleasant to these animals and might had been found irritant and offensive. Similarly, many farmers replied that the microbial fermented fish solution also protected their crops from blue bull for ≥ 30 days.

Published: August 2022

The aim of this paper is to study the application of eco-fibres as a new approach to achieve the multifunctional design for children’s clothing toward sustainability in the clothing industry. In this regard, this study focuses on the evaluation of the fabrics’ mechanical properties including tensile strength and microstructural details as critical points for multifunctional children's clothing purposes. The eco-fibre fabrics studied are organic cotton twill and recycled polyester. Studies have proven that frequent laundering and dry-cleaning result in increased pilling. Furthermore, high quality of colour fastness properties was found in 100% organic woven cotton fabric and recycled polyester fabric printed by non-harmful dyes. Organic cotton fabric is found to offer minimum tear resistance due to the lower strength of cotton fibres. The study found very good physical properties of organic cotton fabric during the mechanical test as well as recycled polyester fabric, which are also safe and eco-friendly. Therefore, these materials are suitable to be used in sustainable clothing design, as it is also a means towards the reduction of environmental pollution and tackle resource depletion associated with the clothing industry.

Authors: Shyam Radhe , Aery N C
Published: August 2022

The effect of various concentrations of three species of cerium was studied on seed germination and early seedling growth of Triticum aestivum L. Seeds were germinated on moist filter papers added with 0.1, 0.5, 2.5, 12.5 and 62.5 Hg g' cerium as cerium chloride, cerium sulphate and cerium nitrate and observations were made on seed germination, shoot- root length, fresh and dry weight. Lower concentrations of cerium species significantly increased shoot-root growth and relative yield of seedlings. Higher concentrations (12.5 and 62.5 Hg g) proved to be toxic for seedling growth. The root growth was affected more adversely than shoots. Though germination speed was affected, ultimate germination was always 100 %. The results of this study indicate that low levels/ concentrations of cerium are beneficial for the test plants.

WHEN SEMIVECTORIAL BILEVEL OPTIMIZATION REDUCES TO ORDINARY BILEVEL OPTIMIZATION
Authors:   Curtin University, School of Electrical Engineering, Computing and Mathematical Sciences, Mathematics and Statistics, Kent St, Bentley WA, Bonnel Henri 
Published: August 2022

The paper deals with semivectorial bilevel optimization problems. The upper level is a scalar optimization problem to be solved by the leader, and the lower level is a multiobjective optimization problem to be solved by several followers acting in a cooperative way inside the greatest coalition, so choosing among Pareto solutions. In the so-called “optimistic problem”, the followers choose among their best responses (i.e. Pareto solutions) one which is the most favorable for the leader. The opposite is the “pessimistic problem”, when there is no cooperation between the leader and the followers, and the followers choice among their best responses may be the worst for the leader. The paper presents a general method which allows, under certain mild hypotheses, to transform a semivectorial bilevel problem into an ordinary bilevel optimization. Some applications are given.

ON CONTROLLABILITY FOR A FRACTIONAL DIFFERENTIAL INCLUSION OF CAPUTO-FABRIZIO TYPE
Authors:   Faculty of Mathematics and Computer Science, University of Bucharest, Cernea Aurelian
Published: August 2022

We consider a fractional differential inclusion involving CaputoFabrizio fractional derivative and we obtain a sufficient condition for h-local controllability along a reference trajectory. To derive this result we use convex linearizations of the fractional differential inclusion. More precisely, we show that the fractional differential inclusion is hlocally controlable around a solution z if a certain linearized inclusion is λ-locally controlable around the null solution for every λ ∈ ∂h(z(T)), where ∂h denotes Clarke’s generalized Jacobian of the locally Lipschitz function h.

In this paper, we point out important observations on time-scale decomposition of linear singularly perturbed systems. It has been established in the control literature that the asymptotically stable fast modes of a singularly perturbed system decay rapidly in a boundary layer interval when the perturbation parameter is very small hence the slow subsystem can serve as a good approximation of the original model. We observe that while this is the case in the steady state, it is not true during the transient response for a strictly proper system with highly damped and highly oscillatory modes. Instead, the fast subsystem provides a very good approximation of the original model’s response but with a DC gain offset. We propose a correction to rectify the DC gain offset and illustrate the findings using an islanded microgrid electric power system model.
QUASI-EXACT SOLVABILITY OF THE D-DIMENSIONAL SEXTIC POTENTIAL IN TERMS OF TRUNCATED BI-CONFLUENT HEUN FUNCTIONS
Authors:   Department of Theoretical Physics, ”Horia Hulubei ” National Institute for Physics and Nuclear Engineering, BUDACA Radu
Published: August 2022

The D-dimensional Schr¨odinger equation for an isotropic sextic potential is brought to a form compatible with the canonical bi-confluent Heun differential equation. The quasi-exactly solvable properties of the model are recovered by considering polynomial solutions for the bi-confluent Heun equation which constrains the potential parameters in terms of rotation quantum number, space dimension and order of the exact solvability. It is shown that the state independence of the potential can be maintained by using a see-saw adjustment between the rotation quantum number and the exact solvability order. An analysis on the exactly solvable instances of the sextic potential is presented in correlation with the extended set of exactly solvable states.

ABSTRAK

 

      Swamedikasi merupakan proses pengobatan yang dilakukan sendiri oleh seseorang mulai dari pengenalan keluhan atau gejalanya sampai pada pemilihan dan penggunaan obat. Penyakit yang bisa ditangani dengan swamedikasi diantaranya adalah diare.  Hasil survei morbiditas diare tahun 2010 menunjukkan bahwa 17,62% penderita diare melakukan swamedikasi. Swamedikasi perlu diwaspadai karena keterbatasan pengetahuan masyarakat untuk penanganan kondisi tersebut yang dapat menyebabkan keterlambatan dalam pengobatan  dengan resiko efek samping yang jarang muncul namun parah, interaksi obat yang berbahaya, dosis tidak tepat, dan pilihan terapi yang salah. Penelitian ini bertujuan untuk menganalisa Tingkat Pengetahuan Masyarakat tentang Swamedikasi Penyakit Diare Kecamatan Ciracas Jakarta Timur

.      Metode penelitian yang digunakan adalah metode deskriptif kuantitatif. Penelitian ini dilakukan terhadap 345 responden sebagai sampel pada bulan Januari-Maret 2021. Pengambilan data dengan menggunakan kuesioner dalam bentuk google form dan diolah dengan program SPSS versi 22.

Upaya untuk mempelajari al-Quran secara menyeluruh merupakan suatu dorongan yang kuat bagi ulama-ulama kaum muslimin terdahulu, bahkan hingga sekarang. Ranting-ranting ilmu yang menopang agar al-Qur’an bisa dikaji secara keseluruhan menjadi perhatian dan dikembangkan, termasuk ilmu Makki dan Madani. Sebagai ranting dari ilmu ulumul Qur’an, tentunya ia dapat ditelaah berdasarkan ilmu pengetahuan yang bertumpu pada tiga cabang filsafat yaitu ontologi, epistemologi, dan aksiologi. Landasan ontologi berkaitan dengan pemahaman seseorang tentang kenyataan, landasan epistemologi memberikan pemahaman tentang sumber dan sarana pengetahuan manusia, dan aksiologi yang memberikan suatu pemahaman tentang nilai hubungan kualitas objek dengan subjek. Dalam kajian ini didapati bahwa ilmu Makki dan Madani walaupun secara teori tidak didapati definisi sekaligus pengertian yang final, namun justru di situlah letak keunikan dan kemanfaatannya yang tidak bisa dinafikan. Pada gilirannya, kajian tentang ayat Makki dan Madani masih relevan untuk dibahas hingga hari ini.
Cybersickness Analysis Using Symbolic Machine Learning Algorithms

Published: August 2022

Virtual reality (VR) and head-mounted displays are constantly gaining popularity in various fields such as education, military, entertainment, and health. Although such technologies provide a high sense of immersion, they can also trigger symptoms of discomfort. This condition is called cybersickness (CS) and is quite popular in recent VR publications. This work proposes a novel experimental analysis using symbolic machine learning to rank potential causes of CS in VR games. We estimate CS causes and rank them according to their impact on the classical machine learning classification task. Experiments are performed using two VR games and 6 experimental protocols along with 37 valid samples from a total of 88 volunteers.
Analyses of Musical Success based on Time, Genre and Collaboration

Published: August 2022

Music is an alive industry with an increasing volume of complex data that can benefit from Computer Science in different ways. Specifically, Music Information Retrieval is a research field aiming to extract meaningful information from musical content. In this work, we analyze musical success from a genre-oriented perspective. Specifically, we model both artist and genre success timelines to detect and predict continuous periods with higher impact. We also build success-based genre collaboration networks to detect collaboration profiles directly related to success. Furthermore, we mine exceptional genre patterns in the networks where the success deviates from the average. Our findings show that studying genre collaboration is a powerful way to assess musical success by describing similar behaviors within collaborative songs. Overall, our work contributes to both the academy and the music industry, as we shed light on the underlying factors of the science behind musical success.

Published: August 2022

This thesis investigates several aspects of computational problems related to circuits and neighborhood exploration. Supported by a vast literature, we explore notable trends in algorithms, optimization, and computational complexity; and we provide some results for each topic discussed. The thesis' contributions are organized into four projects: (i) the study of SUCCINCT MONOTONE CIRCUIT CERTIFICATION (SMCC); (ii) the study of BEST-CASE ENERGY COMPLEXITY IN SATISFYING ASSIGNMENTS (MINEC+M); (iii) the proposition of the Th-hierarchy as an alternative to the hierarchy of complexity classes so-called W-hierarchy; and (iv) the study of the MAXIMUM MULTI IMPROVEMENT problem. Over the course of these four projects, we develop polynomial and parameterized reductions, NP-completeness proofs, classical and parameterized complexity analysis, and implementations of exact algorithms and metaheuristics.

Infraestruturas de Chaves Públicas tem sido amplamente utilizadas em alguns contextos onde se deseja estabelecimento de confiança entre duas entidades. Em especial, seu uso é difundido no estabelecimento de confiança para acesso aos chamados “sites seguros”, através do SSL/TLS. Entretanto, com o advento de iniciativas como a ICP-Brasil e o uso crescente da certificação digital para assinatura digital de documentos eletrônicos, algumas limitações e dificuldades de implementação de ICPs tornaram-se mais evidentes. Este artigo discute a inversão de alguns conceitos de Infraestruturas de Chaves Públicas (ICP) para simplificar o processo de validação de uma assinatura digital. Alterando a forma que um certificado digital é emitido e modificando as responsabilidades de uma Autoridade Certificadora através da criação da Autoridade de Validação, que também substitui a principal função da Autoridade de Carimbo de Tempo, podemos reduzir o esforço de validação de uma assinatura digital. Propomos também um protocolo para interação com a Autoridade de Validação.

A proliferação de aplicações baseadas em web tem aumentado a exposição das empresas a uma variedade de ameaças. Há várias etapas no ciclo de vida das aplicações que são destinadas a prevenir ou mitigar essas ameaças. Os testes de segurança são muito úteis, desde que sejam eficientes. Este trabalho foca a validação dos testes de segurança das aplicações web e propõe uma metodologia para validação de ferramentas e testes de segurança, baseada em árvores de ataques, derivadas das vulnerabilidades conhecidas e divulgadas pelas comunidades de segurança afins. Para validar a eficácia dos testes derivados dessas árvores de ataque, inserem-se vulnerabilidades nas aplicações através de técnicas de Mutação de Código.

Soluções práticas para o desenvolvimento de aplicações distribuídas tolerantes a faltas bizantinas tem sido alvo de pesquisas nos últimos anos. Tais soluções visam oferecer resistência aos sistemas contra ataques de todos os tipos, inclusive maliciosos, tornando-os assim tolerantes a intrusões. Recentemente, o uso de virtualização para construção de um ambiente confiável tem sido considerado por alguns desses trabalhos. Este artigo apresenta SMIT, uma arquitetura tolerante a intrusões que toma proveito de uma área de memória compartilhada entre máquinas virtuais residentes em uma máquina singular para simplificar o protocolo de consenso. O artigo também apresenta uma abordagem distribuída para SMIT, que utiliza um modelo híbrido de falhas.
