Published: July 2022

One of the main concerns across all kinds of domains has always been security. With the crime rates increasing every year the need to control has become crucial. Among the various methods present to monitor crime or any anomalous behavior is through video surveillance. Nowadays security cameras capture incidents in almost all public and private place if desired. Even though we have abundance of data in the form of videos they need to be analyzed manually. This results in long hours of manual labour and even small human discrepancies may have huge consequences negatively. For this purpose, a Convolution Neural Network (CNN) based model is built to detect any form of abnormal activities or anomalies in the video footages. This model converts the input video into frames and detects the anomalous frames. To increase the efficiency of the model, the data is de-noised with Gaussian blur feature. The avenue dataset is used in this work to detect and predict various kinds of anomalies. The performance of the model is measured using classification accuracy and the results are reported.

Authors: Babulal Choudhary Leeladevi , Sharma Anand
Published: July 2022

Millions of devices are predicted to be connected via the Internet of Things (IoT), which is a promising technology for the future. In numerous industries, interest in leveraging the Internet of Things is predicted to expand. Various IoT applications in the healthcare industry are being studied, and the potential for IoT to improve healthcare will be huge. The rise in communications is likely to result in mountains of data, posing a danger to data security. The architecture's gadgets are substantially smaller and less powerful. Due to their complexity, traditional encryption algorithms are computationally demanding, requiring a significant number of rounds for encryption, and draining the limited power of devices. A less sophisticated method, on the other hand, may jeopardise the desired result. Many encryption techniques have recently been suggested to guarantee the security of data transmission across the Internet of Things. Because it requires less memory and is simple to implement in both hardware and software, of all the algorithms, the Tiny Encryption Algorithm (TEA) seems to be the most appealing. TEA has a number of flaws, particularly when it comes to equivalent keys and matching key assaults. As a result, in this study, we present "AL-TEA: An Alternative TEA Technique for Healthcare Images in the IoT," a lightweight encryption algorithm.

Published: July 2022

Several types of antiviral vaccines have been developed to control the spread of the disease since COVID-19 pandemic onset. Currently, many countries are taking measures aimed at increasing vaccination rates for herd immunity formation. However, with increased number of vaccinated individuals, there are more reports of possible adverse events after vaccination, including chronic dermatoses aggravation.
The article describes a clinical case of polymorphic dermal vasculitis (hemorrhagic and urticaria types combination) flare up after COVID-19 vaccination in a 73-year-old woman, who was admitted to Department of Dermatology and Venereology (Sechenov University) with complaints of skin rashes in the trunk, upper and lower extremities and intense itching. The presence of comorbid diseases (ischemic heart disease; atrial fibrillation; chronic gastritis; diverticular colon disease; chronic kidney disease) and wide range of drugs intake on a regular basis made it difficult to diagnose. Due to appropriate therapy, clinical remission was achieved 2.5 months after treatment onset as a complete rashes regression on the trunk and upper extremities. The patient was given recommendations to maintain achieved therapeutic effect.
The Discussion section provides up to date statistical data on the frequency of skin reactions adverse events after various COVID-19 vaccines administration and discusses possible hypotheses for such side reactions manifestation. Recommendations are given to practicing dermatologist about possible chronic dermatoses exacerbation after vaccine administration. When deciding on vaccination, potential risks should be assessed individually and each patient should be informed accordingly. Despite developed management protocols for patients with a new coronavirus infection, treatment options are still limited. The clinical experience accumulated during the pandemic period shows that COVID-19 vaccination significantly reduces disease severity, minimizes lethal outcome and restrains pandemic outbreak. Therefore, there are no certain dermatological diseases as absolute contraindications to COVID-19 vaccination.

BACKGROUND: The implementation of the major federal projects in the Arctic region of the Russian Federation claims particular attention to the indicators of the quality of life and the state of population health in these regions. Health and demographic indicators can be one of the available tools for public health monitoring.
AIM: To analyze the main trends of the health and demographic processes in the arctic regions of the Republic of Sakha (Yakutia) over 20 year (20002020).
MATERIAL AND METHODS: The data of the Territorial Body of the Federal State Statistics Service in the Republic of Sakha (Yakutia), YARMIATS for 20002020 were analyzed. An approximate 95% confidence interval was calculated over 20 years (20002019), the average population growth rate was estimated by a chain method for time series (data for 2020 year are presented separately due to the deformation of the pattern of demographic indicators due to the epidemic SARS-CoV-2). A linear regression analysis of IBM SPSS Statistics 26 was performed to assess the birth and mortality rate trends.
RESULTS: From 20002020, the population of the Arctic region of the Republic of Sakha (Yakutia) decreased by 22% due to migration and high mortality rates. Deaths by external causes occupy approximately 20% of the structure of the all-cause mortality rate. Dynamically, the decrease in the number of infant mortalities was noticed due to the effective routing of pregnant women and improvement of the maternity service in the region.
CONCLUSION: The analysis of the medical and demographic indicators showed positive and negative trends in the Arctic regions public health of the Republic of Sakha (Yakutia). The system of the healthcare organization in the regions is to be improved. Also, these regions, which possess all the features of the healthcare systems with low-density population territories, can become a model for the regional and federal projects approbated in the field of Arctic medicine.

Published: July 2022

Despite the increasing number of e-counsellors, there is a lack of studies especially in the Malaysian context that highlight the skills and practices among e-counsellors and how these are linked to their perceptions when providing e-counselling. This study identifies the relationship between e-counselling skills, e-counselling ethics and e-counselling limitations with counselling self-efficacy among e-counsellors in Malaysia. A total of 159 e-counsellors from various institutions in Malaysia participated in this online survey study. The respondents were selected using the simple random sampling method. The Counselling Self-Estimate Inventory was adopted, and three self-constructed scales were employed for data collection purposes. Correlation analysis found that e-counselling skills (r = 0.597, p < 0.001), e-counselling ethics (r = 0.201, p < 0.001) and e-counselling limitations (r = -0.511, p < 0.001) were significantly correlated to counselling self-efficacy. The structural equation model analysis confirmed the model of relationship between e-counselling skills, e-counselling ethics, e-counselling limitations and counselling self-efficacy. From the three dimensions, e-counselling limitations predicted counselling self-efficacy the best (β value = -0.60), followed by e-counselling ethics (β value= 0.56) and e-counselling skills (β value= 0.18). The findings imply that the extent of e-counsellors’ perceptions on the limitations present in e-counselling play an important role to predict the variance in counselling self-efficacy among e-counsellors. Professional counselling bodies, supervisors and counsellor educators are urged to design a more comprehensive educational and training programme for counsellors. Both counsellor candidates and professional counsellors will benefit from this study as it provides insights for more effective implementation of e-counselling.

Authors:   Center for Language Research, School of Computer Science and Engineering, The University of Aizu, Aizuwakamatsu-shi, Japan, Roy Debopriyo
Published: July 2022

Topic-based intelligent content design with a better understanding of semantic web schemas could be the new focus for technical communication (TC) pedagogy in academia - a major shift away from designing standalone static documents. A new such TC course focused on the basics of how XML, RDFS, and OWL schema contribute to the semantic web for CCMS and CDP, including the basics of how faceted search works and ontology creation happens for simple e-commerce based, tourism, healthcare, and consumer product information design. The course also attempted to expose students to a basic understanding of iiRDS – the standard that enables dynamic information request and delivery in the era of the Internet of Things and Industry 4.0; and how Microsoft HoloLens - a mixed reality platform caters to intelligent information processing in Toyota and smart city contexts, as case studies. This was an introductory course with conceptual development being the focus, and not programming skills. With this course, we wanted to introduce students to the new industry documentation standards and initiate a process in pedagogy that will ultimately lead to bridging the extreme shortage of qualified job applicants in the industry coming from content strategy as a new field of practice. This paper focused on a pilot study initiating an exercise to explore the extent to which such a course helps teach information management in an English as Foreign Language (EFL) context for computer science majors, within the scope of content language integrated learning (CLIL) and project-based language learning (PBLL).

Authors: Pratolo Suryo , Mukti Arifin Hamsyah , Sofyani Hafiez
Published: July 2022

Research aims: This study aims to examine the role of internal control on the service quality of community health centers in handling the COVID-19 pandemic with transparency and accountability budget management as intervening variables.Design/Methodology/Approach: The population of this study was all community health centers located in the Special Region of Yogyakarta Province. The cluster sampling technique was used in determining the samples. Eighty-two community health centers participated in this study. Data were collected by distributing questionnaires. Partial Least Square (PLS) was employed to test the hypotheses.Research findings: The results revealed that, during the COVID-19 pandemic, internal control implementation was not associated directly with the service quality of the community health center. Instead, the association was mediated by transparency, not accountability. Additionally, transparency independently was associated with service quality.Theoretical contribution/Originality: This study extends the literature by examining the role of good governance mechanisms and principles in the community health center context by positioning transparency and accountability as intervening. In addition, this research was conducted in the context of the COVID-19 pandemic, where the service quality of community health centers has a crucial role in dealing with people exposed to COVID-19.Practitioner/Policy implication: The results of this study can be used as input for the relevant regulator to improve the service quality of community health centers through good governance practices.Research limitation/Implication: This research only involved community health centers in the Special Region of Yogyakarta Province as samples.
PDC Control for Mobile Robot Formations with Virtual Reference Based on Separation-Bearing
Authors: Septyan Mamat
Published: July 2022

This paper presents a development of leader-follower formation control using separation-bearing control (SBC) and Parallel Distribution Compensation (PDC) control. The formation control involves tracking of each desired trajectory by leader and follower robots. The follower trajectory is generated using SBC approach with respect to predefined trajectory of the leader. This design is used to improve formation control when initial error is given to leader. In order to maintain the formation and avoid internal collision, the error tracking of each robot must be kept near zero. Each robot is controlled by kinematic and dynamics controller which is designed using PDC and PID. The velocity reference for dynamic robots is limited. The simulation result shows the tracking errors for position and orientation with initial lateral error set at 0.5 m are less than 0.5 m and 1.2 rad which then converges to the desired value. Thus, the good trajectory formation tracking is achieved.

Published: July 2022

Generator noise can be categorized as monotonous noise, which is very annoying and needs to be eliminated. However, noise-cancelling is not easy to do because the algorithm used is not necessarily suitable for each noise. In this study, generator noise was obtained by recording near the generator (outdoor signal) and from the room (indoor signal). Noise generator exploration is carried out to determine whether the noise signal can be removed using the Adaptive LMS method. Exploration was carried out by analyzing statistical signals, spectrum with Fast Fourier Transform (FFT) and Inverse FFT (IFFT), and analyzing the frequency distribution of the remaining noise. The results showed that the correlation coefficients were close to each other. Outdoor and indoor signals are at low frequency. The behavior of FFT and IFFT if described in two dimensions, namely real and imaginary axes, formed a circle with a zero center and has parts that come out of the circle. It confirms that noise-cancelling with adaptive LMS can be realized well even though some noise is still left. The residual noise has formed an impulse that showed normally distributed with mean=-0.0000735 and standard deviation =0.000735. This indicates that the residual noise was no longer disturbing.

Introducción: Los artefactos explosivos improvisados son armas no convencionales que pueden provocar múltiples lesiones y dejar esquirlas a modo de cuerpos extraños que pueden contener metales tóxicos, con potencial afectación a la salud de las víctimas según reportes datados desde 1977, los cuales mencionan alta mortalidad por cáncer y otros síntomas compatibles con toxicidad crónica Objetivo: Describir los resultados de investigación que informen sobre la toxicidad crónica producida por metales en personas víctimas de artefactos explosivos improvisados con esquirlas internalizadas, y sus posibles relaciones con cáncer. Metodología: Revisión sistemática exploratoria de literatura publicada y gris que se realizó entre los meses de marzo a mayo de 2021 en diferentes repositorios de tesis y bases de datos (Scielo, Pubmed, Academic Search Complete, JSTOR, Biblioteca Virtual en Salud, Freepdf, Google Académico, Open Grey); sin límite temporal o geográfico. Se incluyeron artículos originales de revistas indexadas o informes finales no publicados, correspondientes a investigaciones científicas con texto completo, en inglés, español y portugués. Resultados: De 56 documentos evaluados, solamente tres cumplieron criterios de inclusión. Todos estaban escritos en idioma inglés. Solo un estudio iraquí abordó población civil y los otros trabajos aludían a veteranos norteamericanos. Los niveles elevados de metales tóxicos, asociados con alteraciones tisulares circunscritas, fueron hallazgos recurrentes. No hubo reportes de patologías instauradas o manejos clínicos. Conclusión: Fue escasa la evidencia científica recabada; sin embargo, sí se han reportado cambios tisulares circundantes a esas esquirlas. Se considera necesario realizar más estudios relacionados con el tema, incluyendo seguimientos a largo plazo de las afectaciones tisulares detectadas.
Optimized Piccolo Lightweight Block Cipher: Area Efficient Implementation
Authors: Mhaouch Ayoub , Elhamzi Wajdi , Abdelali Abdessalem Ben , Atri Mohamed
Published: July 2022

Piccolo algorithm is one of the lightweight block ciphers designed specifically for low-resource devices which present physical constraints in terms of area, power, and memory. Various hardware architectures for Piccolo block cipher have been proposed in recent years with the aim of obtaining a more appropriate low-resource design for specific constrained applications. The latter must meet real-time processing constraints without affecting the need for hardware resources. Finding a good compromise between computation time and implementation resource consumption is a major consideration in the design process. In this paper, we suggest six serial hardware architectures for Piccolo lightweight algorithm with a 128 bits key length. Proposed architectures are compared to existing designs based on hardware resource occupancy, latency, and throughput. Also, we tested the security of the Piccolo algorithm, and the obtained results show the good robustness of the Piccolo block cipher against statistical attacks. Thus, we can use the Piccolo algorithm in lightweight applications that require a high level of privacy.
Embedded Implementation of Social Distancing Detector Based on One Stage Convolutional Neural Network Detector
Authors: Said Yahia , Ayachi Riadh
Published: July 2022

The recent COVID-19 is a very dangerous disease that intimidates humanity. It spreads very fast and many rules must be respected to reduce its prevalence. One of the most important rules is the social distance which means keeping a safe distance between two persons. A safe distance must be one meter or more. Respecting such rules in public spaces is a very challenging task that needs the assistance of artificial intelligence tools. In this paper, we propose a social distance detector using convolutional neural networks. The detector was based on the Yolo model with a custom-made backbone to guarantee real-time processing and embedded implementation. The backbone was optimized to make it suitable for embedded resources. The inference model was evaluated on the Pynq platform. The model was trained and fine-tuned using the MS COCO dataset. The evaluation of the proposed model proved its efficiency with a precision of 87.98% while running in real-time. The achieved results proved the efficiency of the proposed model and the proposed optimization for embedded implementation.

Authors: Zhang Jianhua , Zhu Qiang , Song Fei , Zhang Lingchao , Wang Juan , Liu Changjun
Published: July 2022

This paper conducts a research on the wavelet construction and application of image edge detection. Taking the image edge detection algorithm based on wavelet modulus maxima as the research subject, this paper discusses the problem of dislocation phenomenon, threshold selection, multi-scale edge fusion and evaluation criterion in the algorithm, and proposes an improved self-adaptive hierarchical threshold algorithm based on information amount and vanishing moment. From the angle of wavelet symmetry, filter composition and vanishing moment, the influence of wavelet property on image edge detection is studied, and the construction requirements of wavelet filter banks for image edge detection are proposed. The constant-length compactly supported biorthogonal wavelet parameterized construction method is used to construct the biorthogonal wavelet featuring odd symmetry for high-pass decomposition filter and unidirectionality for filter sequence, and the improved algorithm of wavelet construction and threshold is applied to the simulation of image edge detection of concrete cracks in ultra-high arch dam.
On Image-Processing-Based Identification Method of Express Logistics Information
Authors: Zhu Lin , Sheng Xin
Published: July 2022

As a modern comprehensive information platform for integrated statistical analysis of express shipments information and for express shipments management decision-making, the express logistics track and trace system needs to use artificial intelligence (AI) technology and image processing technology to automatically extract the text content of express logistics documents. Existing express shipments information identification models usually have problems such as less-than-ideal performance in detecting single characters or small text regions of express logistics documents, high human resource cost for character-level markup, and low speed and accuracy of text recognition. In response, this paper studies the image-processing-based identification method of express logistics information. It presents a recognition process for pre-processing text images of express logistics documents, along with a detailed description of denoising, greyscaling and binarisation methods. While proposing an enhancement strategy for Chinese characters in the section of handwritten Chinese, this paper constructs a model for recognition of express shipping document texts based on bidirectional long-short term memory (LSTM) and attention mechanism. In this way, we fully mined key semantic information of express logistics document texts. The experimental results verify the effectiveness of the constructed model.

Published: July 2022

Michigan State University (MSU) is home to one of the largest library comics collections in North America, holding over three hundred thousand print comic book titles and artifacts. Inspired by the interdisciplinary opportunity offered by digital humanities practice, a research collaborative linked to the MSU Library Digital Scholarship Lab (DSL) developed a Collections as Data project focused on the Comic Art Collection. This team extracted and cleaned over forty-five thousand MARC records describing comics published in Canada, Mexico, and the United States. The dataset is openly available through a GitLab repository, where the team has shared data visualizations so that scholars and members of the public can explore and interrogate this unique collection. In order to bridge digital humanities with the popular culture legacy ofthe institution, the MSU comics community turned to bibliographic metadata as a new way to leverage the collection for scholarly analysis. In October 2020, the Department of English Graphic Possibilities Research Workshop gathered a group of scholars, librarians, Wikidatians, and enthusiasts for a virtual Wikidata edit-a-thon. This project report will present this event as a case study to discuss how linked open metadata may be used to create knowledge and how community knowledge can, in turn, enrich metadata. We explore not only how our participants utilized the open-access tool Mix’n’match to connect the Comic Art Collection dataset to Wikidata and increase awareness of lesser-known authors and regional publishers missing from OCLC and Library of Congress databases, but how the knowledge of this community in turn revealed issues of authority control.
La corriente pedagógica cooperaria
Authors: Yorg José Alberto , Ramírez Zarza Ana María
Published: July 2022

El presente trabajo constituye el resultado de una reflexión extendida y estudio de lo que entendemos como significante del cooperativismo en la educación desde el pensamiento de Robert Owen en esa esfera, poniéndolo en tensión con los modelos educativos actuales. Las sucesivas reformas educativas implementadas en el mundo entero, con el eufemismo de «educación de calidad» y otras denominaciones fracasan una detrás de las otras. Por otro lado, hay una necesidad también de publicar este segundo trabajo sobre esta temática construida sobre la base de aquel trabajo denominado «La génesis de la Pedagogía Cooperaria», replicando puntos substanciales de él, porque es necesario insistir en que no es posible ser fiel al ideario cooperativo implementando cursos, conferencias y seminarios de educación cooperativa bajo los lineamientos pedagógicos liberales absorbidos en los institutos de formación docente. Hemos recibido muchas críticas y algunos consejos en nuestra persistencia de que el cooperativismo posee su pedagogía sui génesis. Nos interrogamos cómo se espera que la educación cooperativa, imbuida de pedagogía liberal —sea por cuestiones de formatos, o por una incorrecta concepción del cooperativismo— y también, a resulta de la crisis educativa, ayude a transformar o cuanto menos indique cambios que demandan nuestras sociedades.

O magistério eclesiástico sobre a doutrina social da Igreja Católica Apostólica Romana relaciona a transcendência salvífica da cooperação ao princípio da subsidiariedade que pondera o grau e o modo de intervenção do Estado em vista do bem comum. Esse magistério encontra no cooperativismo uma forma de integração entre a ciência e a fé numa razão prática para as comunidades economicamente organizadas. O principio da subsidiariedade não encontra positivação em um dispositivo específico da Constituição Federal do Brasil. Mas, a contemplação ali da liberdade de constituição de cooperativas como garantia fundamental da cidadania cominado com o comando ao Estado de estímulo e promoção ao cooperativismo na ordem econômica constitucional são eloquentes pelos quais se pode inferir que o Direito brasileiro reconhece nas cooperativas a excelência que resta expressa na teologia cristã quanto ao caráter radicalmente comunitário da vivência feliz em sociedade. Donde se pode concluir que o princípio da subsidiariedade está incorporado de modo implícito ao corpo do Estado Democrático de Direito no Brasil

Workers’ cooperatives as a tool to promote labour market inclusion for migrants
Authors: Arrieta Idiakez Francisco Javier , López Rodríguez Josune , Martínez Etxeberria Gonzalo
Published: July 2022

The aim of this study is to identify the ways in which worker cooperatives can promote labour market inclusion for migrants. To that end, first, we will refer to the legal literature that supports the suitability of the cooperative formula in order to achieve the aforementioned purpose. By means of this analysis, our main contributions will be the following: the description of the channels that worker cooperatives offer to regularise the entrance and the work of migrants in the European Union, avoiding this way different phenomena, such as, smuggling of migrants, human tracking or informal work; the description of the contribution of worker cooperatives to the integration process of migrants, paying special attention to their training-learning and their potential, the different initiatives of social entrepreneurship and the creation of networks and associations with local communities that favour the assistance, counsel and social cohesion; and the study of the ways in which Public Administrations can promote workers cooperatives taking into account their contribution to favour decent work for migrants.

Soutenabilité de la dette publique post initiative pays pauvres très endettés (PPTE) : une évidence empirique au Togo
Authors: Napo Fousséni , Essiomle Koffi Biova
Published: July 2022

L'objectif de ce papier est d'analyser la soutenabilité de la dette publique du Togo à long terme après initiative Pays Pauvres Très Endettés (PPTE). La période d'étude couvre de 1994 à 2019. A partir des tests de stationnarité et cointégration, les résultats montrent que la dette du Gouvernement togolais est faiblement soutenable à long terme. En effet, la persistance du déficit budgétaire suite à l'insuffisance de ressources internes pour faire face à la hausse des dépenses budgétaires, notamment celles des dépenses d'investissement, a obligé l'État togolais à faire appel aux emprunts, entraînant alors l'accroissement du niveau de la dette ces dernières années. Au regard de ces résultats, une rigueur budgétaire est plus qu'une nécessité à travers, la contraction des dépenses budgétaires, mais surtout, la fiscalisation progressive du secteur informel et une mobilisation plus accrue des impôts sur le foncier.
L'effet des politiques d'aide à la santé sur le développement sanitaire et économique en Afrique subsaharienne

L'objectif de ce papier est d'analyser l'effet des politiques d'aide à la santé sur le développement sanitaire et économique en Afrique subsaharienne sur la période 2002-2018. La méthodologie adoptée repose sur la méthode des moments généralisés (GMM) en système en panel dynamiques. Les résultats après estimations révèlent que, seules les aides accordées à la santé de Base et à la santé de la reproduction améliorent l'état de santé des populations. Pour une augmentation de 1% de ces aides, on peut sauver respectivement environ 6 et 2 vies sur 1000 naissances vivantes. Les résultats révèlent également que le capital santé (taux de mortalité infanto-juvénile) a un effet négatif sur le niveau du PIB à hauteur de 0,003%. Il ressort également que le service de la dette impacte négativement le PIB à hauteur de 0,003%. Cette recherche recommande donc l'orientation des politiques d'aide à la santé dans les pays de l'Afrique subsaharienne vers les dépenses pro-pauvre tels que la santé de base, la santé de la reproduction tout en allégeant les services de la dette pour permettre la capacité des pays pauvres à investir dans le capital humain tel que la santé.
Urbanisation et inégalités de revenu en Afrique subsaharienne : quel rôle pour la gouvernance traditionnelle et la e-gouvernance?
Authors: Sanoussi Yacobou , Adeve Komlan Ametowoyo , Wonyra Kwami Ossadzifo
Published: July 2022

Cet article vise à analyser le rôle de la gouvernance traditionnelle et le e-gouvernance dans la relation urbanisation-gouvernance-inégalités de revenu dans les pays de l'Afrique subsaharienne. Pour y parvenir, les données de panel sont mobilisées sur 48 pays couvrant la période 2005-2016. Une modélisation dynamique est adoptée et la méthode LSDVC est utilisée pour estimer notre modèle. Les résultats relèvent que l'urbanisation renforce les inégalités dans les pays de l'Afrique subsaharienne. Cependant, l'utilisation des services de télécommunications et la qualité des services publics croisées avec l'urbanisation réduisent les inégalités de revenu.

Pobyt Maksymiliana Habsburga na zamku w Krzepicach przed bitwą pod Byczyną (1587/1588)
Authors: Kobus Andrzej
Published: July 2022

Artykuł poświęcony jest pobytowi Maksymiliana Habsburga na zamku w Krzepicach na przełomie lat 1587/1588. Omawia liczebność sił, z którymi król elekt przybył do Krzepic, oraz warunki, jakie tutaj zastał. Ukazuje kontakty zagraniczne, nawiązywane z Krzepic przez Maksymiliana Habsburga. Opracowanie naświetla także zagadnienia związane z obecnością poselstw i gości, przybywających do króla elekta do Krzepic od grudnia 1587 do stycznia 1588 r. Zakończenie artykułu stanowi opis wymarszu Maksymiliana Habsburga z Krzepic do Wielunia w połowie stycznia 1588 r. Poza sprawami dyplomatycznymi i wojskowymi artykuł porusza też kwestię poparcia, jakim w Rzeczypospolitej cieszyła się kandydatura Maksymiliana Habsburga na tron polski w 1587 r. Zwraca uwagę na sympatię względem Habsburga na terenie Wielkiego Księstwa Litewskiego i w Wielkopolsce. Porusza też zagadnienie wsparcia, jakiego Maksymilian spodziewał się z pobliskiego Śląska, oraz kwestię, na ile jego oczekiwania zostały spełnione. Istotną rolę odgrywał tutaj Wrocław, najważniejsze spośród miast śląskich, z którego do Krzepic wiódł znany szlak handlowy, łączący to miasto z Krakowem jako stolicą Rzeczypospolitej Obojga Narodów.
