Published: June 2023

Purbayan Tourism Village is one of 17 tourist villages that received a decree from the Yogyakarta City Government, located in Kotagede. This area has a unique cultural potential that exhibits both historical and cultural wealth in the form of traditions that exist even today. These traditions include traditional culinary arts, silversmithing and batik craft. However, the potential of this cultural heritage is not visible when compared to the development of the Purbayan Tourism Village. Promotional efforts from business groups and tourism are lacking synergy. Based on these problems, this community service activity aims to assist Micro, Small and Medium Enterprises (MSMEs) to design synergistic tourism promotions. MSMEs that became community service partners are Kopi Lumbung Mataram culinary shop and Studio 76 silver art school. The implementation of this activity uses a user-centered approach to design thinking. In this method, partners as users are actively involved in Focus Group Discussions and workshops on content design and tourism promotion strategies in synergy. The activities described in this paper are understanding, observing, defining point of view, and ideation phase of design thinking. The activity resulted in the promotion concept of Studio 76 silver art school in the form of a draft booth design for silver making exhibitions and photography designs for culinary products of Warung Kopi Lumbung Mataram. Promotion synergy between the two MSMEs is carried out by combining the two tourism service products into an interactive exhibition. The collaboration of these MSME’s aims to promote and increase the number of visitors to the area.
Cartesian Reachability Logic: A Language-parametric Logic for Verifying k-Safety Properties
Authors: Tušil Jan , Serbanuta Traian , Obdrzalek Jan 
Published: June 2023

We introduce a language-parametric calculus for k-safety verification - Cartesian Reach- ability logic (CRL).In recent years, formal verification of hyperproperties has become an important topic in the formal methods community. An interesting class of hyperproperties is known as k-safety properties, which express the absence of a bad k-tuple of execution traces. Many security policies, such as noninterference, and functional properties, such as commutativity, monotonicity, and transitivity, are k-safety properties. A prominent example of a logic that can reason about k-safety properties of software systems is Cartesian Hoare logic (CHL). However, CHL targets a specific, small imperative language. In order to use it for sound verification of programs in a different language, one needs to extend it with the desired features or hand-craft a translation. Both these approaches require a lot of tedious, error- prone work.Unlike CHL, CRL is language-parametric: it can be instantiated with an operational semantics (of a certain kind) of any deterministic language. Its soundness theorem is proved once and for all, with no need to adapt or re-prove it for different languages or their variants. This approach can significantly reduce the development costs of tools and techniques for sound k-safety verification of programs in deterministic languages: for exam- ple, of smart contracts written for EVM (the language powering the Ethereum blockchain), which already has an operational semantics serving as a reference.
How Much Should This Symbol Weigh? A GNN-Advised Clause Selection
Authors: Bártek Filip , Suda Martin 
Published: June 2023

Clause selection plays a crucial role in modern saturation-based automatic theorem provers. A commonly used heuristic suggests prioritizing small clauses, i.e., clauses with few symbol occurrences. More generally, we can give preference to clauses with a low weighted symbol occurrence count, where each symbol’s occurrence count is multiplied by a respective symbol weight. Traditionally, a human domain expert would supply the symbol weights.In this paper, we propose a system based on a graph neural network that learns to predict symbol weights with the aim of improving clause selection for arbitrary first-order logic problems. Our experiments demonstrate that by advising the automatic theorem prover Vampire on the first-order fragment of TPTP using a trained neural network, the prover’s problem solving capability improves by 6.6% compared to uniformly weighting symbols and by 2.1% compared to a goal-directed variant of the uniformly weighting strategy.
Trace-based Deductive Verification

Published: June 2023

Contracts specifying a procedure’s behavior in terms of pre- and postconditions are essential for scalable software verification, but cannot express any constraints on the events occurring during execution of the procedure. This necessitates to annotate code with intermediate assertions, preventing full specification abstraction.We propose a logic over symbolic traces able to specify recursive procedures in a mod- ular manner that refers to specified programs only in terms of events. We also provide a deduction system based on symbolic execution and induction that we prove to be sound relative to a trace semantics.Our work generalizes contract-based to trace-based deductive verification by extending the notion of state-based contracts to trace-based contracts.
Keep me out of the loop: a more flexible choreographic projection
Authors: Cruz-Filipe Luís , Montesi Fabrizio , Rasmussen Robert R. 
Published: June 2023

Choreographic programming is a paradigm where programmers write global descrip- tions of distributed protocols, called choreographies, and correct implementations are au- tomatically generated by a mechanism called projection. Not all choreographies are pro- jectable, because decisions made by one process must be communicated to other processes whose behaviour depends on them – a property known as knowledge of choice.The standard formulation of knowledge of choice disallows protocols such as third-party authentication with retries, where two processes iteratively interact, and other processes wait to be notified at the end of this loop. In this work we show how knowledge of choice can be weakened, extending the class of projectable choreographies with these and other interesting behaviours. The whole development is formalised in Coq. Working with a proof assistant was crucial to our development, because of the help it provided with detecting counterintuitive edge cases that would otherwise have gone unnoticed.

Views of Exercise in People With Systemic Sclerosis: A Qualitative Study
Authors: Frade Stephanie , Campbell Chloe , Bird Stephen P. , Cameron Melainie 
Published: June 2023

ABSTRACT

Background
Systemic sclerosis (SSc) is a connective tissue autoimmune disease that results in significant reduction in physical function and quality of life. Exercise may offer health benefits in people with autoimmune disease, yet approximately 50% of people with SSc are physically inactive and experience a wide array of barriers that may impede their exercise engagement. Currently, there are no exercise recommendations or guidelines for this population. In this qualitative study, we explore and describe barriers and facilitators to exercise in adults with SSc, aiming to provide person-centerd exercise recommendations for people with SSc.

Methods
Adults with SSc were purposefully recruited to represent diversity in disease type, duration, and manifestations. Three online focus groups were conducted to explore barriers and facilitators to exercise in people with SSc, transcribed, and thematically analyzed.

Results
Twenty-three adults with SSc (mean age 59 ± 11 years, 91% female) participated. Four themes emerged: (a) disease-related and general barriers to exercise, (b) perceived change in personal exercise capacity postdiagnosis, (c) beneficial effects of exercise, and (d) preference for modified supervised exercise.

Conclusion
SSc imposes disease-related barriers that, combined with general barriers, impede exercise engagement. People with SSc understand that exercise is potentially beneficial. Key recommendations and advice to counter these barriers include (a) ensuring a comfortable temperature to exercise, (b) using modified equipment (e.g., adjustable weighted straps), (c) individually supervising and modifying exercise as required, and (d) keeping people with SSc accountable and motivated to exercise.

OBJECTIVE
The authors aimed to explore the clinical outcomes and risk factors related to recurrence of and survival from solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) that were reclassified according to the 2021 WHO classification of central nervous system (CNS) tumors.

METHODS
The authors retrospectively collected and analyzed the clinical and pathological data of SFTs and HPCs recorded from January 2007 to December 2021. Two neuropathologists reassessed pathological slides and regraded specimens on the basis of the 2021 WHO classification. The prognostic factors related to progression-free survival (PFS) and overall survival (OS) were statistically assessed with univariate and multivariate Cox regression analyses.

RESULTS
A total of 146 patients (74 men and 72 women, mean ± SD [range] age 46.1 ± 14.3 [3–78] years) were reviewed, and 86, 35, and 25 patients were reclassified as having grade 1, 2, and 3 SFTs on the basis of the 2021 WHO classification, respectively. The median PFS and OS of the patients with WHO grade 1 SFT were 105 months and 199 months after initial diagnosis; for patients with WHO grade 2 SFT, 77 months and 145 months; and for patients with WHO grade 3 SFT, 44 months and 112 months, respectively. Of the entire cohort, 61 patients experienced local recurrence and 31 died, of whom 27 (87.1%) died of SFT and relevant complications. Ten patients had extracranial metastasis. In multivariate Cox regression analysis, subtotal resection (STR) (HR 4.648, 95% CI 2.601–8.304, p < 0.001), tumor located in the parasagittal or parafalx region (HR 2.105, 95% CI 1.099–4.033, p = 0.025), tumor in the vertebrae (HR 3.352, 95% CI 1.228–9.148, p = 0.018), WHO grade 2 SFT (HR 2.579, 95% CI 1.343–4.953, p = 0.004), and WHO grade 3 SFT (HR 5.814, 95% CI 2.887–11.712, p < 0.001) were significantly associated with shortened PFS, whereas STR (HR 3.217, 95% CI 1.435–7.210, p = 0.005) and WHO grade 3 SFT (HR 3.433, 95% CI 1.324–8.901, p = 0.011) were significantly associated with shortened OS. In univariate analyses, patients who received adjuvant radiotherapy (RT) after STR had longer PFS than patients who did not receive RT.

CONCLUSIONS
The 2021 WHO classification of CNS tumors better predicted malignancy with different pathological grades, and in particular WHO grade 3 SFT had worse prognosis. Gross-total resection (GTR) can significantly prolong PFS and OS and should serve as the most important treatment method. Adjuvant RT was helpful for patients who underwent STR but not for patients who underwent GTR.
Hydrocephalus in the emergency department: descriptive nationwide data and analysis of transfer
Authors: Piatt Joseph 
Published: June 2023

OBJECTIVE
Hydrocephalus is a chronic, treatable, but in most cases incurable condition characterized by long periods of stability punctuated by crises. Patients in crisis usually seek care in an emergency department (ED). How patients with hydrocephalus use EDs has received almost no epidemiological study.

METHODS
Data were taken from the National Emergency Department Survey for 2018. Visits by patients with hydrocephalus were identified by diagnostic codes. Neurosurgical visits were identified by codes for imaging of the brain or skull or by neurosurgical procedure codes. Visits and dispositions were characterized by demographic factors for neurosurgical and unspecified visits by using methods for analysis of complex survey designs. Associations among demographic factors were assessed using latent class analysis.

RESULTS
There were an estimated 204,785 ED visits by patients with hydrocephalus in the United States in 2018. Roughly 80% of patients with hydrocephalus who visited EDs were adults or elders. By a ratio of 2:1, patients with hydrocephalus visited EDs much more often for unspecified reasons than for neurosurgical reasons. Patients with neurosurgical complaints had more costly ED visits, and if they were admitted they had longer and more costly hospitalizations than did patients with unspecified complaints. Only 1 in 3 patients with hydrocephalus who visited an ED was sent home regardless of whether the complaint was neurosurgical. Neurosurgical visits ended in transfer to another acute care facility more than 3 times as often as unspecified visits. Odds of transfer were more strongly associated with geography and, specifically, with proximity to a teaching hospital than with personal or community wealth.

CONCLUSIONS
Patients with hydrocephalus make heavy use of EDs, and they make more visits for reasons unrelated to their hydrocephalus than for neurosurgical reasons. Transfer to another acute care facility is an adverse clinical outcome that is much more common after neurosurgical visits. It is a system inefficiency that might be minimized by proactive case management and coordination of care.
Radiation doses and accuracy of navigated pedicle screw placement in cervical and thoracic spine surgery: a comparison of sliding gantry CT and mobile cone-beam CT in a homogeneous cohort
Authors: Baumgart Lea , Ille Sebastian , Kirschke Jan S. , Meyer Bernhard , Krieg Sandro M. 
Published: June 2023

OBJECTIVE
Multiple solutions for navigation-guided pedicle screw placement are currently available. Intraoperative imaging techniques are invaluable for spinal surgery, but often there is little attention paid to patient radiation exposure. This study aimed to compare the applied radiation doses of sliding gantry CT (SGCT)– and mobile cone-beam CT (CBCT)–based pedicle screw placement for spinal instrumentation.

METHODS
The authors retrospectively analyzed 183 and 54 patients who underwent SGCT- or standard CBCT-based pedicle screw placement, respectively, for spinal instrumentation at their department between June 2019 and January 2020. SGCT uses an automated radiation dose adjustment.

RESULTS
Baseline characteristics, including the number of screws per patient and the number of instrumented levels, did not significantly differ between the two groups. Although the accuracy of screw placement according to Gertzbein-Robbins classification did not differ between the two groups, more screws had to be revised intraoperatively in the CBCT group (SGCT 2.7% vs CBCT 6.0%, p = 0.0036). Mean (± SD) radiation doses for the first (SGCT 484.0 ± 201.1 vs CBCT 687.4 ± 188.5 mGy*cm, p < 0.0001), second (SGCT 515.8 ± 216.3 vs CBCT 658.3 ± 220.1 mGy*cm, p < 0.0001), third (SGCT 531.3 ± 237.5 vs CBCT 641.6 ± 177.3 mGy*cm, p = 0.0140), and total (SGCT 1216.9 ± 699.3 vs CBCT 2000.3 ± 921.0 mGy*cm, p < 0.0001) scans were significantly lower for SGCT. This was also true for radiation doses per scanned level (SGCT 461.9 ± 429.3 vs CBCT 1004.1 ± 905.1 mGy*cm, p < 0.0001) and radiation doses per screw (SGCT 172.6 ± 110.1 vs CBCT 349.6 ± 273.4 mGy*cm, p < 0.0001).

CONCLUSIONS
The applied radiation doses were significantly lower using SGCT for navigated pedicle screw placement in spinal instrumentation. A modern CT scanner on a sliding gantry leads to lower radiation doses, especially through automated 3D radiation dose adjustment.
