Abstract This paper presents an intuitive approach for mobility analysis of thin-panel origamis based on a coplanar 2-twist screw system, which consists of a pair of parallel/concurrent line vectors. In this study, we first proved that in any thin-panel origami, the allowable instantaneous mobility for any two facets connected to a third one can be described by a coplanar 2-twist screw system because this mobility is generated by two coplanar creases in the third facet. Second, the mobility of the basic origami units with a single facet loop was analyzed by using this coplanar 2-twist screw system. Third, the mobility analysis approach was extended to analyze the mobility of other planar/circular arraying origami patterns with multiple facet loops; typical origami patterns such as leaf-fold, Miura-ori were subjected to this analysis process. Furthermore, we proved that the proposed approach can be applied to the mobility analysis of complicated origamis; this approach proved to be considerably more intuitive than the traditional approach for mobility analysis.

The goal of this paper is to demonstrate that the Modified Gru¨bler-Kutzbach Criterion when combined with a simple procedure for determining the reciprocal screws offers a direct and simple method for analysing highly complex mechanisms including the over-constrained parallel manipulators. Since the scalar product of screws is not dependent on the choice of the origin, one can quickly obtain a simple expression of screws by selecting an appropriate coordinate system. In such simple expression, the coordinates of a screw would include 0 or 1, and thus greatly simplifies the procedure for determine the number of constraints in a mechanism. Seven rules have been presented to help simplify the analysis process. The advocated approach makes it possible to determine, within minutes, the mobility of a highly complex mechanism by using a pencil and a paper. Many over-constrained mechanisms, including three parallel mechanisms, are presented as examples.

The Way

The paper in hand is an attempt to apply discourse analysis approach to analyze the use of illeism in poetic eloquence. Illeism is used in third-person self-reference forms for representing the views of someone else as distinctive technique of interpretation. Through this means, it creates illusion of the speaker linguistically and thematically trying to distance themselves in the narrative. The paper is an analysis of Taylor Swift’s poem “Why She Disappeared” for her sixth studio album ‘Reputation’. The study explores qualitatively poetry elements in accordance to highlight the implication of illeism through signifiers. It utilizes a literary approach and the poem as the corpus of the study. The aims of the study are to address the way illeism functioning within the poem and the interpretation of the third-person self-reference in the poem. It is found that the poem presents the use of illeism in threefold: (1) it is used to distance oneself from traumatic occurrences; (2) it is used to refer to past-self indirectly; (3) it is used to give self-motivation. The third-person terms mentioned in the poem contribute to the actions that the speaker is employing through the discourse. Further study is needed to explore more about illeism in a variety of discourse.

Conceptual Study

The paper considers several issues of Russian Verse Theory connected with the architectonics of Lermontov’s Borodino strophe. This rare and unique strophe is characterized by an odd number of lines (seven), peculiar rhyme, and mainly by the different number of syllables in its lines: five lines of the strophe contain nine syllables of iambic tetrameter, while the third and the seventh contain six syllables of iambic trimeter. Such a structure does not allow the use of traditional (statistical) methods of the study of verse rhythmics. To prove that, this paper describes the construction of “stress profiles” for the quatrain in iambic tetrameter, and shows that it is impossible to carry out this procedure for Lermontov’s Borodino strophe. Unlike the traditional approach, our method of rhythmic-harmonic precision imposes no restrictions on the architectonics of verse, which is why it is this method that underlies the analysis of the structural harmony of the Borodino strophe given in this paper. Our analysis compares the rhythmic-harmonic potential of the strophe and the actual values of the rhythmic harmony parameter with iambic and trochaic quatrains and with Onegin’s strophe in Pushkin’s verse. Another task of our work was a rhythmic-conceptual study of the “Borodino” text. This poem was published in 1837; together with the poem “On the Poet’s Death,” it immediately moved Lermontov to the forefront of Russian poets. The main result of our work consists in proving that in its structural-harmonic aspect, the Borodino strophe is unique and, moreover, it turns out to be the perfect verse construction for the expression of a mixed sublime-descending poetic mood: inspiration (in our case, a patriotic rise) and the following disappointment. Our study shows that Lermontov’s great poem “Borodino” not only passes “the trial of harmony with algebra,” but also, from the point of view of its single a rhythm-sense, stands near the best works of the first Russian poet, Pushkin.

This paper presents methods for improving the attention span of workers in tasks that heavily rely on their attention to the occurrence of rare events. The underlying idea in our approach is to dynamically augment the task with some dummy (artificial) events at different times throughout the task, rewarding the worker upon identifying and reporting them. The proposed approach is an alternative to the traditional approach of exclusively relying on rewarding the worker for successfully identifying the event of interest itself. We propose three methods for timing the dummy events throughout the task. Two of these methods are static and determine the timing of the dummy events at random or uniformly throughout the task. The third method is dynamic and uses the identification (or misidentification) of dummy events as a signal for the worker's attention to the task, adjusting the rate of dummy events generation accordingly.

As a method, hermeneutics play important role in the study of texts, languages, and all things related to the text, including the sacred text. This study is related to the text producer (author), the text itself, and the reader. In this article, the author tries to integrate hermeneutics of Latin American school of Jorge J. E. Gracia with the rules of interpretation of the Qur’an. The authors initiate describing the thought of Gracia using a descriptive-comparative analysis approach, then compare it with Qur’an studies, which in this case is compliance with the rules of interpretation of the Qur’an. Related to understanding term, Gracia put in one of understanding terminology of interpretation. There are three meanings of interpretation: first, the term ‘interpretation’ is synonymous with comprehension (understanding) of a person to the meaning of the text, the second on ‘interpretation’ is also often used to refer to the process or activity to develop an understanding of the text, and the third, interpretation that involves three factors. 1) the interpreted text or called interpretandum, 2) The interpreter, and, 3) the comments added to the original text, or called interpretans. Those three awareness are closely related to the interpreted text, or if it is integrated with the rules of interpretation will result the integration of hermeneutics with the following principles: First, the historical functions in line with the asbāb an-nuzul; second, meaning function with linguistic rules and the Qur’an; fourth, implicative function, reviewing the patterns of linkages with other scientific text. Hermeneutika menduduki posisi penting dalam kajian teks, bahasa, dan segala hal yang berkaitan dengan teks, termasuk teks suci. Kajian ini berhubungan dengan produsen teks (author), teks itu sendiri, dan pembaca (reader). Dalam artikel ini, penulis mencoba menawarkan sebuah integrasi hermeneutika mazhab Amerika Latin ala Jorge J. E. Gracia dengan kaidah-kaidah penafsiran al-Qur’an. Dengan menggunakan pendekatan analisa deskriptif-komparatif, penulis memulai mendeskripsikan pemikiran Gracia, kemudian mengomparasikan dengan kajian qur’anic studies, yang dalam hal ini adalah kesesuaiannya dengan kaidah-kaidah penafsiran al-Qur’an. Dalam kaitannya dengan pemahaman, Gracia memasukkan term understanding dalam salah satu terminologi interpretasi. Setidaknya ada tiga pengertian dari interpretasi; pertama, istilah ‘interpretasi’ itu sama artinya dengan pemahaman (understanding) yang dimiliki seseorang terhadap makna teks; kedua, ‘interpretasi’ yang juga sering digunakan untuk merujuk proses atau aktivitas mengembangkan pemahaman dari teks; dan ketiga, interpretasi dalam pengertian ketiga melibatkan tiga faktor. 1) teks yang ditafsirkan, atau disebut interpretandum, 2) Penafsir itu sendiri, dan; 3) komentar yang ditambahkan ke dalam teks aslinya, atau disebut interpretans. Secara spesifik tiga kesadaran tersebut erat kaitannya dengan teks yang sedang ditafsirkan. Jika diintegrasikan dengan kaidah-kaidah penafsiran akan menghasilkan integrasi hermeneutika dengan kaidah-kaidah sebagai berikut: Pertama, fungsi historis (historical function) sejalan dengan asbāb an-nuzul; kedua, fungsi makna (meaning function) dengan kaidah kebahasaan al-Qur’an dan; keempat, fungsi implikatif (implicative function) meninjau pola keterkaitan teks dengan keilmuan lainnya.

Today's transportation problems are found in the complex interactions of social, financial, economic, political, and engineering issues. The traditional approach to analyzing transportation problems has been the top-down approach, in which a set of overall objectives is defined and specific parts are fitted in the overall scheme. The effectiveness of this analysis process has been challenged when many issues need to be addressed at once and the individual parts participants to decisions have greater autonomy. A factor contributing to this phenomenon is the greater opportunity and power for individual parts to communicate and to interact with one another. As a result, it has become increasingly difficult to predict or control the overall performance of a large system, or to diagnose particular phenomena. In the past decade, the concept of agent-based modeling has been developed and applied to problems that exhibit a complex behavioral pattern. This modeling approach considers that each part acts on the basis of its local knowledge and cooperates and/or competes with other parts. Through the aggregation of the individual interactions, the overall image of the system emerges. This approach is called the bottom-up approach. This paper examines the link between today's transportation problems and agent-based modeling, presents the framework of agent based modeling, notes recently used examples applied to transportation, and discusses limitations. The intent of this paper is to explore a new avenue for the direction of modeling and analysis of increasingly complex transportation systems.

Aim. Identification and construction of the typology of attitudes of health care professionals in Ukraine to the current COVID-19 situation and vaccination process. Methods. Transcripts of 49 semi-structured interviews subjected to thematic analysis constituted the subject matter of the analysis. On the basis of the categories identified within the thematic analysis process, a typology was developed, with due account of two parameters: the idea about the origin of the virus: artificial or natural, and the attitude of the informants to the policy (implementation of policy decisions) chosen by the authorities to fight the virus. Combination of these two parameters gives four standpoints—types of attitude of health care professionals to the risks associated with COVID-19. Results and conclusion. Analysis of the results has enabled to outline the problem field for assessing the risk of COVID-19, which includes three topics, as well as to point out four typical standpoints in the attitude displayed by health care professionals that are marked as “magical thinking,” “technological thinking,” “negativistic thinking,” “critical thinking.” Originality. The research was conducted during the third wave of coronavirus in Ukraine, therefore, it reflects the analysed opinions of health care professionals about the threat of COVID-19 and vaccination process. The fact that the research was performed using qualitative methods ensured focusing on subjective peculiarities of the perception of changes in the COVID-19 situation.
