Introduction. Metabolic navigation with 5‑ALA is one of methods for intraoperative imaging in neuro‑oncology.Aim. To perform a comparative analysis of sensitivity of metabolic navigation with 5‑ALA during surgery of primary and secondary brain tumors of various histological nature and degree of malignancy.Materials and methods. During the period from 2013 to 2020, our group have performed surgery to 403 patients using metabolic navigation: microsurgical resections were performed in 384 people with brain tumors, 220 of them were with glial tumors, 101 were with intracranial meningiomas, 63 were with metastatic brain damage. Among patients with metastases, 39 patients had a solitary injury, 16 had a multi‑focal injury, so 72 cases of metastatic nodes were considered in this group. Stereotactic biopsies with 5‑ALA‑assistance were performed in 19 people. Metabolic navigation was performed with the drug 5‑ALA, which was taken orally at a dose of 20 mg/kg 2 hours before surgery. Intraoperative fluorescence was evaluated using microscope with a fluorescent module.Results. Metabolic navigation using microscope has a high sensitivity when employed during microsurgery (including repeated implementation of surgery) in cases of anaplastic gliomas (65 % in total, 58 % with bright glow), glioblastomas (94 % in total, 53 % with bright glow), intracranial meningiomas (94 % in total, 64 % – with bright glow). The use of 5‑ALA has significant limitations in sensitivity in cases of diffuse gliomas (46 % – in total, 27 % – with bright glow) and brain metastases (in total 87 % – for the solid part, 52 % – for the bed, with bright glow – 51 %). In diffuse gliomas, the glow areas had significantly higher proliferative index and cell nuclei density than the fluoronegative zones. Among the most important factors affecting the glow of gliomas it can be noted: the status of the IDH1 mutation, the volume of the contrasting part of the glioma according to MRI data, the methionine accumulation index according to positron emission tomography, the tumor blood flow indicators according to the arterial spin marking method – ASL perfusion.Conclusions. Implementation of 5‑ALA navigation with the use of microscope provides high sensitivity in cases of glioblastomas, anaplastic gliomas (especially for detecting of non‑contrasting part of tumor that is not visually altered in the white light of operating microscope) and brain meningiomas. The method is less effective in low‑grade gliomas and intracranial metastases.

Background. The article is extremely relevant due to growing traumatism, current condition of craniofacial traumatology, debatable and incomplete tactics of restoring traumatic defects and deformations of bones of the skull and face. Plastic surgery of the skull defects has developed from simple defect closure to restoring an aesthetically attractive area of the skull, which shape repeats the individual structure of the area lost due to trauma or surgical treatment (trepanation surgery, osteoplastic trepanation, treatment of a depressed skull fracture, etc.). To restore the defects specialists use auto‑ and allografts. In recent years, materials to manufacture implants are simulated using a 3D‑shape.Aims. To describe the clinical case of a combined approach for the restoration of post‑traumatic deformation of the bones of the arch, base of the skull and bones of the middle zone of the face. To show the importance of multidisciplinary teams in providing assistance to this group of patients, as well as the use of individual 3D simulated titanium plates for reconstructive operations. Emphasize the need to perform reconstructive operations as soon as possible.Materials and methods. Patient Sh., 43 years old, was admitted to the neurosurgical department of the City Clinical Emergency Hospital (Minsk), in the long term severe traumatic brain injury, with defects of the arch and base of the skull and deformation of the bones of the facial skull on the left. Titanium implants were modeled on a 3D printer, which were used during the operation performed by a multidisciplinary team consisting of a neurosurgeon, maxillofacial surgeon and ophthalmologist‑surgeon. Us for closing defects in the cranial vault, the bottom wall of the orbit and in eliminating deformation skeleton midface line. Titanium implants are made by specialists of Medbiotech SP LLC, Minsk, Republic of Belarus.Results. The late postoperative period proceeded without peculiarities, the wounds healed by primary tension. Post-operative CT showed that the condition of the implants is satisfactory.Conclusion. This clinical observation demonstrated the need for a multidisciplinary approach, as well as the priority in using 3D simulated titanium implants to restore post‑traumatic deformation of the bones of the arch and base of the skull and midline bones.

Published: December 2022

Background. Cerebral arteriovenous malformations and dural arteriovenous fistulas are relatively rare pathologies with frequency of 1–1.5 and 0.1–0.2 cases per 100 000 people per year, respectively. Probability of a combination of these pathologies in a single patient is extremely low. The authors were not able to find publications describing a combination of these pathologies of the cerebral vasculature.Aim. To present a clinical case of successful surgical treatment of combined cerebral pathology – dural arteriovenous fistula and angiographically occult arteriovenous malformation – in a patient with intracranial hemorrhage.Materials and methods. Analysis of the results of treatment of patient with dural arteriovenous fistula with hemorrhagic disease course at the N.V. Sklifosovsky Research Institute of Emergency Medicine (Moscow) was performed. The patient underwent osteoplastic cranial trepanation, resection of the dural arteriovenous fistula. Intraoperatively an angiographically occult arteriovenous malformation was detected which caused the hemorrhage.Results. Surgical treatment allowed to achieve a satisfactory outcome. Intraoperatively diagnosed angiographically occult arteriovenous malformation was confirmed histologically.Conclusions. The presented clinical observation shows the necessity of careful revision of hematoma cavity in the presence of isolated intraparenchymal hemorrhage from dural arteriovenous fistula.
Aneurysm of the primitive trigeminal artery: a clinical case and a literature review
Authors: Goroshchenko S. A. , Rozhchenko L. V. , Bobinov V. V. , Kolomin E. G. , Petrov A. E. 
Published: December 2022

Background. The primitive trigeminal artery is a fetal anastomosis connecting carotid and vertebrobasilar basins during embryonic period of development. After birth, this artery in the child is obliterated and reduced in most cases. Sometimes the obliteration does not occur and as a result the aneurysms may be formed on this artery (due to change in ordinary hemodynamics in carotid basin), as a consequence, it produces a risk of subarachnoid hemorrhage that sharply worsens prognosis of the disease outcome. The usual microsurgical treatment methods of aneurysms of such localization are of little use and are highly traumatic due to the very “low” location of the neck, because the surgery may need extended basal accesses requiring resection of skull base bones. Also, an “open” surgery produces risks of perforating arteries injury that often extend from trigeminal artery and feed the brain stem, the injury will immediately result in brain ischemic damage. That is why the preferred method for treatment of that kind of pathology may include endovascular intervention both of non‑reconstructive type employing microcoils only and those of reconstructive requiring implantation of assisting or flow‑redirecting stents.Aim. To demonstrate a case of successful treatment of patient with a primitive trigeminal artery aneurysm.Materials and methods. A woman, who was admitted to clinic with complaints of convergent strabismus, undergone surgery for large aneurysm located on primitive trigeminal artery. CT brain angiography revealed large aneurysm of primitive trigeminal artery on the right, the result was later confirmed by data of selective cerebral subtraction angiography. Taking into account oculomotor disorders in the patient, it was decided to refrain from microcoils use due to risk of the mass‑effect preservation. Under double disaggregant therapy (ticagrelor 90 mg twice daily + acetylsalicylic acid 100 mg once daily in the evening) and monitoring the functional activity of platelets, a flow‑deflecting stent was implanted into the right internal carotid artery.Results. The patient was discharged from hospital on the 1st day after the surgery and returned to work. A control angiography performed 3 years later revealed a total shutdown of the aneurysm from bloodstream as well as a partial regression of oculomotor disorders. Intravascular treatment in this situation served as an effective method of choice and made it possible to reliably turn off the aneurysm from bloodstream without impairing the functional outcome of patient’s treatment.Conclusions. It can be assumed that intravascular intervention in case of such aneurysms serves as an effective method of choice as minimally invasive and low‑traumatic surgery in the treatment of patients with that type of pathology.
Tales from “THE disK FILES”: Lessons Learnt from a Data Recovery Project in 2003–2006 at the National Archives of Australia
Authors: Pearson David , Doig James 
Published: December 2022

ABSTRACT
This case study re-evaluates a large-scale project carried out by the National Archives of Australia (NAA) between 2003 and 2006. The project aimed to identify obsolete digital media (physical data carriers) in its collection and to describe and recover the data from the carriers using a third-party data recovery provider.1 A detailed process for data recovery was developed that included the capture of a full audit trail of steps in the data recovery process. The project was completed in four stages: phase 1 obtained bit-level images from the carriers; phase 2 extracted individual bit-files from the carriers; phase 3 identified duplicate files and proprietary or complex file formats; and phase 4 was a final report that documented processes, made recommendations on future processes, and provided lessons learned. Recent work described in this article indicates that files extracted from the carriers in 2004–2005 can be accurately rendered in current computer environments. The ongoing significance of the project is that it is an early demonstration of the success of bit-level preservation and the need to create disk images as part of a preservation workflow, suggesting a sustainable methodology for digital preservation. The project also influenced archival policy at the NAA and influenced the development of subsequent software tools that became widely known in the broader digital preservation community. The focus on archival principles of authenticity, integrity, chain of custody, and provenance of the recovered records were key learnings to ensuring long-term access and usability. Finally, the metrics resulting from the project, for example, rates of readable carriers and rates of data recovery by carrier type, are useful data from a point in time that correspond quite closely to similar data recovery projects undertaken by other institutions at about the same time and provide a benchmark for future research.
Level Up! Lessons Learned from Six Years of Collaborative Technical Skills Development
Authors: Eckard Max , Gadelha Elizabeth , Shallcross Mike 
Published: December 2022

ABSTRACT
As academic and cultural heritage institutions increasingly offer digital collections and services, technical upskilling—the process of acquiring and/or expanding technical skills—has moved from an individual prerogative to an institutional imperative. In this publication, the authors share their experiences with, and lessons learned from, a series of four collaborative technical skills development initiatives—the ArchivesSpace-Archivematica-DSpace Workflow Integration Project (2014–2016), a series of Curation Team Workshops (2015), a Technical Skills Pilot Project (2017–2018), and the development of a Bentley Audiovisual Quality Control Utility (2019)—at the University of Michigan Bentley Historical Library. In doing so, the authors advocate for the value of increasing the technical literacy and skills of entire teams/units (as opposed to focusing on the development of individual skills) and provide information and best practices that will enable and empower other institutions to undertake similar initiatives. They conclude by making the case for organizational cultures that value learning together.
Redesigning Program Assessment for Teaching with Primary Sources: Understanding the Impacts of Our Work

Published: December 2022

ABSTRACT
This article describes how redesigning a program's assessment practices for teaching with primary sources (TPS) can provide a clear framework for talking about the impact of educators' work in archives and can provide feedback on how to refine instruction practices for greater results. The authors share a description of their assessment redesign process accompanied by analysis of the implementation of our new assessment tool in the hope others will consider the design and goals of their own assessment practices. The authors' work demonstrates that reflection on existing tools, development of new goals, and design of new assessment strategies can yield inspiring new data on program impact and highlight areas for improvement. By illustrating the authors' redesign process, this article also demonstrates the types of impacts and outcomes that educators can measure for TPS and points to the huge potential of TPS in local history contexts and elsewhere. The authors' revised student assessment moved archives staff from relying on self-reported, affect-focused data to better understanding the outcomes of their work with students: the impact of project-based learning in archives; the value that students find in various aspects of their encounters with archives; the role that TPS in local history contexts plays in connecting students to their community; and the transferability of research skills that students learn through TPS activities.
Reference Staffing and Scheduling Models in Archives and Special Collections: A Survey Analysis of Prepandemic Practices
Authors: Hawk Amanda K. 
Published: December 2022

ABSTRACT
Reference services form the core function of any type of library. Even when faced with shrinking budgets and staff sizes, library and archives workers continue to provide reference services to meet the demands of researchers. Yet a critical analysis of the internal systems used for archival and special collections reference work is lacking compared to the robust body of research about users of collection materials. This article presents findings from a national survey about reference staffing and scheduling models in archival and special collections repositories conducted immediately prior to the onset of the COVID-19 pandemic. The survey data revealed specific models for staffing and scheduling used by participating institutions, respondents' level of satisfaction with staffing and scheduling models, and the most common challenges and successes related to reference services. The responses also conveyed information about the number of special collections and archives staff participating in reference services, the average length and frequency of shifts, and typical service hours. The findings indicated overall satisfaction among respondents in terms of their unit's staffing and scheduling models, with larger institutions reporting higher satisfaction rates across all categories than smaller institutions. Yet many survey participants reported budget constraints and staffing shortages that negatively impact public services operations. Although the results do not pinpoint a single approach to reference staffing and scheduling that will work for all archives and special collections units, qualitative responses suggest that successful reference models depend on sufficient staffing, internal buy-in and cooperation among employees, and support from supervisors and administration.
Toward Metaliteracy and Transliteracy in the History Classroom: A Case Study Among Underserved Students
Authors: Cobourn Alston Brake , Brown Jen Corrinne , Warga Edward , Louis Lisa 
Published: December 2022

ABSTRACT
In the last twenty years, scholars have reimagined information literacy to better address an overly saturated world of information and the growing participatory culture of Web 2.0. Outside of library and information science (LIS), researchers have promoted transliteracy—the intersection between information, visual, digital, and other literacies—to help students find and assess information. Within the LIS discipline, metaliteracy has provided a foundation to rethink information literacy frameworks, redefining students as creators who produce and share information. Relatively few studies exist, however, on how to leverage literacies in support of student digital scholarship projects. Likewise, digital humanities professors promote metaliteracy in the classroom, yet fewer scholars create digital humanities projects or write case studies about them outside of research institutions, prestigious private colleges, and larger, well-established public history programs. This case study examines a class project for a small undergraduate Introduction to Public History course at Texas A&M University–Corpus Christi (TAMU–CC), a regional university with a comparatively large population of historically underserved students. Working with one archivist, two librarians, and the professor, students established a digital home for the ongoing South Texas Stories oral history project. Through this project, students learned and practiced various aspects of primary source literacy, information literacy, visual literacy, and digital literacy. The authors argue that such digital projects promote both metaliteracy and transliteracy, offering students a holistic learning experience during which they can practice their skills and that these types of projects are feasible at all kinds of institutions, even those with largely historically underserved populations.
Professional Career Building in the Archival Field: Studying the Archives Leadership Institute
Authors: Soyka Heather 
Published: December 2022

ABSTRACT
This article explores the ongoing and long-term impacts of programs that support new modes of professional growth, particularly cohort-based programs that focus on the goals of community and network building, through a case study of the Archives Leadership Institute (ALI). This study seeks to understand how and why programs such as ALI assist and support archivists with their professional careers and wonders about the ways in which the profession benefits more broadly from programs like this. Ultimately, this article finds that programs such as ALI often benefit the professional careers of individual archivists, but that the broader impact for the field merits additional consideration and thought. Finally, this article draws together patterns, feedback, challenges, and suggestions for thinking about and developing future initiatives that support the growth of the archival field.
IMPROVEMENT OF VOLTAGE STRESS ON MOTOR CONTROL HARDWARE VIA OPTIMAL LOCATION OF RC SNUBBER CIRCUIT
Authors: SARIAYDIN Mehmet Emin , AĞALAR Şener 
Published: December 2022

While the increase in the customer failure rate in the consumer electronics sector affects the manufacturers negatively in terms of cost. It has also become one of the issues that cause customer loss and customer satisfaction. In addition to the economic losses, during the production and distribution of the spare parts and products that are changed at the customer's home due to the reliability problems experienced in the field, extra carbon emissions are released to the nature for this operation. For these reasons, it has become important to reduce the rate of customer failure.
With the increase in electronic components, the quality and reliability precautions that may occur in the electronic circuits, have become the subject of study today. As in many white goods products, it is advantageous to have variable speed motors in refrigerators due to energy efficiency and energy regulation issues. For this reason, the compressor of refrigerator comes to the forefront as the component that dissipates the highest power proportionally. With the use of variable speed compressors, the need for an electronic board with including power conversion and motor driving capability has arisen.
In this paper, RC Snubber circuits have been studied in order to prevent quality problems that may occur due to high switching frequency in flyback converter topology, which is one of the DC-DC converters that provide isolation. The methods in the literature based on the location of the RC Snubber in the circuit and the determination of its related values were examined and experiments were made on the simulation program. At the same time, a test mechanism was set up on the variable speed compressor motor control card of the refrigerator and measurements were taken with the help of an oscilloscope. The measurements taken in the simulation program and the experimental environment were compared.

Published: December 2022

The Sarak Opat as one of the customary institutions in Aceh have been authorized to settle disputes of minor cases at the village level in Central Aceh, Aceh, Indonesia. This is guaranteed by the applicable laws and regulations. However, the practice of resolving minor cases is currently delegated to the judiciary. Therefore, this study was a legal empirical or sociological research to analyze primary and secondary data in Central Aceh Regency. Data collection method employed were direct interviews with selected informants, and the collected data were processed in qualitative analysis method. The results showed that the role of the Sarak Opat customary institution in resolving minor cases in the Gayo community in Central Aceh has a strong legal basis as mandated by various national and regional legal policies. Subsequently, the customary institution has two considerations in delegating minor criminal cases to the judiciary. First, the litigants are dissatisfied with the sanctions decided by Sarak Opat. Second, the officials of Sarak Opat lack understanding of their authority as a customary justice institution.
