Risk Prediction of Emergency Department Visits in Patients With Lung Cancer Using Machine Learning: Retrospective Observational Study
Authors: Lee Ah Ra , Park Hojoon , Yoo Aram , Kim Seok , Sunwoo Leonard , Yoo Sooyoung 
Published: December 2023

Background
Patients with lung cancer are among the most frequent visitors to emergency departments due to cancer-related problems, and the prognosis for those who seek emergency care is dismal. Given that patients with lung cancer frequently visit health care facilities for treatment or follow-up, the ability to predict emergency department visits based on clinical information gleaned from their routine visits would enhance hospital resource utilization and patient outcomes.

Objective
This study proposed a machine learning–based prediction model to identify risk factors for emergency department visits by patients with lung cancer.

Methods
This was a retrospective observational study of patients with lung cancer diagnosed at Seoul National University Bundang Hospital, a tertiary general hospital in South Korea, between January 2010 and December 2017. The primary outcome was an emergency department visit within 30 days of an outpatient visit. This study developed a machine learning–based prediction model using a common data model. In addition, the importance of features that influenced the decision-making of the model output was analyzed to identify significant clinical factors.

Results
The model with the best performance demonstrated an area under the receiver operating characteristic curve of 0.73 in its ability to predict the attendance of patients with lung cancer in emergency departments. The frequency of recent visits to the emergency department and several laboratory test results that are typically collected during cancer treatment follow-up visits were revealed as influencing factors for the model output.

Conclusions
This study developed a machine learning–based risk prediction model using a common data model and identified influencing factors for emergency department visits by patients with lung cancer. The predictive model contributes to the efficiency of resource utilization and health care service quality by facilitating the identification and early intervention of high-risk patients. This study demonstrated the possibility of collaborative research among different institutions using the common data model for precision medicine in lung cancer.
Powerful Politicians, Political Costs, and Income Smoothing
Authors: Jung Sumi 
Published: December 2023

ABSTRACT
This paper investigates whether and how firms receiving benefits through their connections to politicians use accounting discretion to mitigate the costs associated with negative publicity. I utilize a unique setting that captures the change in political costs arising from chairmanship appointments to influential U.S. Senate committees. Firms in the home state of a promoted officeholder often receive preferential treatment, drawing public scrutiny and incentivizing them to avoid reporting extreme earnings through income smoothing to reduce adverse political attention. Employing a difference-in-differences research design, I find evidence that home-state firms smooth their earnings throughout the officeholder’s tenure following a senator’s promotion to chairman or ranking minority member. Cross-sectional analyses demonstrate that these effects are stronger for firms anticipating higher political costs. Overall, this paper provides evidence of the political cost hypothesis, highlighting the role of political connections in shaping firms’ financial reporting strategies.

Published: December 2023

OBJECTIVE
To determine whether adiposity depots modulate vaspin levels and whether vaspin predicts type 2 diabetes (T2D) risk, through epidemiological and genetic analyses.

RESEARCH DESIGN AND METHODS
We assessed the relationship of plasma vaspin concentration with incident and prevalent T2D and adiposity-related variables in 1) the Prospective Urban and Rural Epidemiology (PURE) biomarker substudy (N = 10,052) and 2) the Outcome Reduction with Initial Glargine Intervention (ORIGIN) trial (N = 7,840), using regression models. We then assessed whether vaspin is causally associated with T2D and whether genetic variants associated with MRI-measured adiposity depots modulate vaspin levels, using two-sample Mendelian randomization (MR).

RESULTS
A 1-SD increase in circulating vaspin levels was associated with a 16% increase in incident T2D in the PURE cohort (hazard ratio 1.16; 95% CI 1.09–1.23; P = 4.26 × 10−7) and prevalent T2D in the ORIGIN cohort (odds ratio [OR] 1.16; 95% CI 1.07–1.25; P = 2.17 × 10−4). A 1-unit increase in BMI and triglyceride levels was associated with a 0.08-SD (95% CI 0.06–0.10; P = 2.04 × 10−15) and 0.06-SD (95% CI 0.04–0.08; P = 4.08 × 10−13) increase, respectively, in vaspin in the PURE group. Consistent associations were observed in the ORIGIN cohort. MR results reinforced the association between vaspin and BMI-adjusted T2D risk (OR 1.01 per 1-SD increase in vaspin level; 95% CI 1.00–1.02; P = 2.86 × 10−2) and showed that vaspin was increased by 0.10 SD per 1-SD decrease in genetically determined gluteofemoral adiposity (95% CI 0.02–0.18; P = 2.01 × 10−2). No relationships were found between subcutaneous or visceral adiposity and vaspin.

CONCLUSIONS
These findings support that higher vaspin levels are related to increased T2D risk and reduced gluteofemoral adiposity, positioning vaspin as a promising clinical predictor for T2D.

Authors: Khofifah Rike Farikha , Savitri Dian 
Published: December 2023

The predator-prey model is the mathematical model that describes the interaction behavior between prey and predator. This research discusses the modified Leslie-Gower model by considering the cannibalism behaviors of the prey that contains Holling type I response function, which is a predator with passive characteristics. The stability analysis stage includes determining the system's solution in the form of an equilibrium point, analyzing the local stability of each equilibrium using eigenvalues, and numerical simulation to synchronize the analysis results. Numerical simulations visualized in phase portraits with Python software. The results of the local stability analysis of the system obtained four equilibrium points, namely, equilibrium points are unstable while is asymptotically stable with certain conditions. The results of numerical simulations show that only the equilibrium point which is asymptotically stable when the environment carries capacity parameters (e=2.1). Meanwhile, when e=2.878 then, only is asymptotically stable. In this research also using two different initial values, it is concluded that whatever the initial value used, the system solution always converges to the equilibrium points dan . Changes in environmental carrying capacity affect the dynamics of system solutions.

Abstract

OBJECTIVE
To describe the signalment, clinical findings, presumptive or definitive diagnosis, and outcome in cats with central cord syndrome (CCS).

ANIMALS
22 cats.

CLINICAL PRESENTATION
Cats evaluated for CCS at 7 referral hospitals between 2017 and 2021 were included. Information retrieved from medical records included signalment, physical and neurological examination findings, diagnostic investigations, definitive or presumptive diagnosis, treatment, and follow-up.

RESULTS
Median age at presentation was 9 years. Two neuroanatomical localizations were associated with CCS: C1-C5 spinal cord segments in 17 (77.3%) cats and C6-T2 spinal cord segments in 5 (22.7%) cats. Neuroanatomical localization did not correlate with lesion location on MRI in 8 (36.3%) cats. The most common lesion location within the vertebral column was over the C2 and C4 vertebral bodies in 6 (27.2%) and 5 (22.7%) cats, respectively. Peracute clinical signs were observed in 11 (50%) cats, acute in 1 (4.5%), subacute in 4 (18%), and chronic and progressive signs were seen in 6 (40.9%) cats. The most common peracute condition was ischemic myelopathy in 8 (36.3%) cats, whereas neoplasia was the most frequently identified chronic etiology occurring in 5 (22.7%) cats. Outcome was poor in 13 (59%) cats, consisting of 4 of 11 (36.6%) of the peracute cases, 3 of 4 (75%) of the subacute cases, and 6 of 6 of the chronic cases.

CLINICAL RELEVANCE
Central cord syndrome can occur in cats with lesions in the C1-C5 and C6-T2 spinal cord segments. Multiple etiologies can cause CCS, most commonly, ischemic myelopathy and neoplasia. Prognosis depends on the etiology and onset of clinical signs.
Rural Landscapes and Affective Encounters in Radu Muntean’s Film, Întregalde
Authors: Sándor Katalin 
Published: December 2023

Abstract
The paper discusses Radu Muntean 2021 film, Î
ntregalde focusing on the representation of rural landscapes and the encounter between different social classes. The film marks multiple displacements within the director’s oeuvre, epitomized as “the chronicler” of the middle class in contemporary Romanian cinema. The spatial displacement from middle class urban spaces towards mountain and rural areas and the shift from the distant picturesqueness of landscape to the experience of landscape as dwelling, as inhabited and sensed environment mediated through textural images enables unsettling embodied, affective encounters both with the natural environment and between different social classes. In this way, the film addresses the question of class differences and lays bare the socio-economic inequalities between the urban middle class and the countryside without reducing rural characters to clichéd figurants in a picturesque or sombre countryside decorum. The film’s critical reflection on a form of occasional humanitarian aid and middle class philanthropy does not relativize the concept of charity, altruism and help but rather points to the growing gap of social inequalities (and the crisis of care) in the context of contemporary capitalism.1
Effect of Special Cement CPA on the Characteristic Properties of Cementitious Materials Based Waste Glass Powder: Poozolanic Activity and Heat Treatment

Published: December 2023

Abstract
The main purpose of this study is to evaluate the effect of curing method on the compressive strength of waste glass powder as a supplementary cementitious material. This work presents an experimental study on the physico-mechanical characterization of waste glass powder (GP) as partial replacement of special cement (Algerian cement without additions CPA) based high performance cementitious material, varying the percentage of GP by 10%, 20% and 30% (by weight of cement), the curing methods: water curing at 20± 2 °C and heat curing by under accelerated drying in an oven at 100 °C (stoving). Half of the mortar samples 40x40x160 mm were treated with stoving just after demolding then kept in the open air, the other half was kept in fresh water in order to evaluate their sustainability and index of Poozolanic Activity (I) at different ages: 7, 28, 90 and 365 days. The compressive strength results showed that there is an increase in compressive strength with the increase in age of the two curing methods but the strength of all mixtures which have been stoved is inferior to those of the same mixtures preserved in fresh water at different ages. The best rate of replacement of the cement by GP is 20% following the results obtained for the compressive strength and Poozolanic Activity Index I.

Published: December 2023

Abstract
A recently created cementing substance noted for its remarkable qualities is reactive powder concrete (RPC). It incorporates fine quartz sand, crushed quartz, silica fume, a low water-to-cement ratio, and a high percentage of Portland cement. In RPC, fine quartz sand completely takes the role of coarse aggregate. This study examines the effects of high-temperature curing on RPC strength while concentrating on the manufacture of RPC in Pakistan using locally accessible materials. In specifically, a compressive strength of more than 142 MPa is one of the desirable hard qualities that must be attained as the main goal. The study uses a variety of test mixtures and curing methods, including heat curing. The major emphasis is on mechanical properties such as compressive strength, split cylinder strength, and flexural strength. The study also investigates how the mechanical properties of RPC are affected by various steel fiber concentrations and curing conditions. With varying quantities of steel fiber and silica fume, more than 100 experimental mixtures are created. In comparison to silica fume levels, which range between 25% and 35% by weight of cement, steel fiber concentrations range from 0% to 3% by total volume. The results demonstrate the effects of curing at 60°C, 70°C, and 90°C. Notably, after 28 days of curing at 90°C, a compressive strength of 142 MPa is attained, suggesting a general rise in compressive strength across all curing methods with curing age.

Authors: Kokate P. , Middey A. , Sadistap S. 
Published: December 2023

Abstract
The rising levels of air pollution in the industrial environment necessitate its monitoring near the sources. The green wall around the industries is a novel and popular to mitigate the impact of Particulate Matter (PM). Such industrial mitigation cannot be monitored through a limited quantity AQ monitoring station at ground level. This paper demonstrates the application of drone aided particulate matter monitoring system to measure the above-ground level PM levels. The drone-aided AQ monitoring system was employed near the thermal power plant to calculate the attenuation factor potential due to the plantation of a green bamboo belt. The wind rose was plotted to understand the wind pattern and dispersion direction of the PM. The dust suppression due to the green wall of the bamboo is calculated using a drone-enabled PM sensor module. The PM (Particulate Matter) data at the ground level was 39 % low compared to the upper height. The PM concentration was significantly high at the height of 30 m Above Ground Level (AGL). The bamboo plant plays a crucial role in dust suppression. The overall results pointed out that the calibrated, lightweight portable drone-aided sensor monitoring system can be reliable for monitoring source-specific industries.

The Concept of Permanent Education – Paradigmatic Approaches
Authors: Eși Marius-Costel 
Published: December 2023

Abstract
When we speak about the concept of “permanent education”, our attention focuses on comprehensive and broad approaches to the instructive-educational process that go beyond, or, at least, should go beyond what we call or we mean by the traditional boundaries of school and formal education. In fact, the lifelong education constitutes sine qua non a continuing process of learning and development throughout life, a process that takes place in various contexts and at different stages of our lifetime. In this context, we can state that the permanent education must be in agreement with everything that means, on the one hand, the educational market, and on the other hand, the economic market corroborated with the idea of the labor market.
We believe that such an assumption is justified by the very demands and new orientations of the labor market as well as by the need of the human being to continuously develop himself in relation to himself and also to everything that is around him. Such a reform of the educational society (Comenius) and of the human being (Dewey), in relation to what the continuous development entails, only brings into discussion a series of ideas such as the continuous learning, the (self) exploration, the personal development and so on.Therefore, the analysis of this paper will focus on the one hand, on the paradigmatic approach to the concept of “permanent education” (from a diachronic and synchronic viewpoint), and on the other hand, on the analysis of specific features of some paradigms related thereof. Thus, we will try to show that its benefits and impact may vary according to individual context and needs.
Learning Management System (LMS) for Academic Inclusion and Learning Agency: An Interpretive Review of Technoprogressivism in ODL Instructional Technology Policy
Authors: Nkambule Bongani , Ngubane Sindile , Mncube Siphamandla 
Published: December 2023

Abstract
Literature frequently describes how ineffective implementation of instructional policy frameworks can make distance learning a lonely and unrewarding academic pursuit, characterized by high student drop-out rates, high failure rates and academic exclusion. In trying to mitigate this catastrophe, academic departments in distance learning institutions utilize learning management systems (LMSs) to stimulate students’ learning experiences. In keeping with techno-progressivism, the researchers (and authors of this paper) turned to extant documentary policy and literature to review – qualitatively – how the University of South Africa’s (Unisa’s) Open Distance Learning Policy (ODLP) promotes academic inclusion and learning agency as cornerstones of student success and social justice, especially in an unequal society like South Africa. The findings revealed the following: 1) Unisa’s ODLP position has the impetus to influence the deployment of the LMS to promote academic inclusion; 2) Practical means of promoting inclusion were mirrored in the provision of manual or electronic learning material, computer laboratories and free internet connectivity in regional centres across all nine provinces of South Africa, as well as in the provision of laptops for National Student Financial Aid Scheme (NSFAS)-funded students, 30 gigabytes of free monthly mobile data to all students, and assistive technologies for students with disabilities; 3) Practical utilization of an LMS to foster self-regulated learning occurred through problem-based individual activities supplemented by asynchronous demonstrative learning material (e.g. audio, video), while collaborative learning agency was enabled through e-tutoring, which afforded students the opportunity to interact with e-tutors and their peers about the learning content; 4) Drawbacks in the use of the LMS stemmed from the insufficiency of assistive learning technologies that are required for students with disabilities to participate fully in online learning, and a corpus of students’ irregular attendance at and participation in e-tutoring discussions and their projection of a negative attitude towards the e-tutors.
About Creativity in History Teaching and Learning
Authors: Neacșa Ramona 
Published: December 2023

Abstract
A high-performing academic education system supports the development of skills such as curiosity and creativity in students’ activities and learning experiences. However, the academic curriculum gives quite a lot of importance to the accumulation of knowledge and the learning of specific skills, which can encourage an education that is less oriented towards the development of creativity and curiosity, especially in the discipline of History. Our study has as target group the 3rd year students of the Pedagogy of Primary and Preschool Education, whom we monitored during two academic years. The purpose of the research is to analyze the effect of the didactic strategy on students’ creative thinking and to show that creativity is a fundamental element for the development of their historical thinking as students and future practitioners. In our approach, we started from the following premises and hypotheses: 1) creativity is present in all learning contexts, although it is not always specified as such; 2) students need to be creative in a constantly changing world that requires us to permanently adapt; 3) outside of those disciplines that explicitly emphasize creativity (fine arts, music etc.) creativity is rarely present in the discussions regarding teaching and learning; 4) if at History we apply a series of strategies to stimulate creative thinking that includes interactive methods, diverse teaching aids and mixed organizational forms which involve cooperation, then students’ creativity, curiosity and interest in this subject will be stimulated. Therefore, we proposed the following objectives: (O1) The implementation of didactic strategies that stimulate students’ creativity; (O2) The analysis of the results - how does the didactic strategy affect creative thinking in the history discipline? (O3) The analysis and evaluation of the effect that the didactic strategy may have on creativity at History. The expected results are, in the case of students, an increase in creativity through the application of certain didactic strategies, motivation for learning and positive attitudes towards history, with the belief that when they become teachers they will apply similar strategies in the classroom.
