Motivational Profiles in Mathematics - Stability and Links with Educational and Emotional Outcomes
Authors: Widlund Anna , Tuominen Heta , Korhonen Johan
Published: January 2023

Grounding on the situated expectancy-value theory, this study investigated stability and change in adolescent students' (N = 508) motivational profiles in mathematics (self-concept, values, costs) during the last year of comprehensive education, and how these changes relate to relevant educational outcomes (mathematics performance and aspirations) and students’ emotional distress (study-related exhaustion and depressive symptoms). Latent profile and latent transition analyses revealed four motivational profiles among students: Positively ambitious (high competence and value beliefs, low costs, T1: 34%/ T2: 32%), Struggling ambitious (high competence and value beliefs, high costs, T1: 25%/T2: 25%), Indifferent (low competence and value beliefs, low costs, T1: 22%/T2: 21%), and Maladaptive (low competence and value beliefs, high costs, 19%/22%). Although some fluctuations were detected in profile memberships within the school year, most of the students (80%) displayed stable mathematics motivation across ninth grade. Students who remained Positively ambitious also performed well, aspired for an education that required high mathematical skills, and experienced the least emotional distress, whereas students in the most negative motivational profile (Maladaptive) showed the opposite patterns. However, students who experienced high math-related costs, despite having positive value beliefs, performance, and aspirations (i.e., Struggling ambitious), also experienced one of the highest levels of study-related exhaustion and depressive symptoms. Elevated levels of exhaustion and depressive symptoms were systematically associated with negative motivational transitions in general (i.e., moving from Positively ambitious to Struggling ambitious, or from Indifferent to Maladaptive), highlighting the importance of reducing perceived study-related costs in schools and supporting students' well-being.
Learning environment-specific learning rates
Authors: Simoens Jonas , Verguts Tom , Braem Senne
Published: January 2023

People often have to switch back and forth between different environments that come with different problems and volatilities. While volatile environments require fast learning (i.e., high learning rates), stable environments call for lower learning rates. Previous studies have shown that people adapt their learning rates, but it remains unclear whether they can also learn about environment-specific learning rates, and instantaneously retrieve them when revisiting environments. Here, using optimality simulations and hierarchical Bayesian analyses across three experiments, we show that people can learn to use different learning rates when switching back and forth between two different environments. We even observe a signature of these environment-specific learning rates when the volatility of both environments is suddenly the same. We conclude that humans can flexibly adapt and learn to associate different learning rates to different environments, offering important insights for developing theories of meta-learning and context-specific control.

Performance Evaluation of Cauliflower Cultivars in Mid-Hills of Nepal for Winter Season Production
Authors: Shrestha Surendra Lal
Published: January 2023

Cauliflower (Brassica Oleracea botrytis) is one of the most popular and demanded vegetables in Nepal. Five cultivars: Barkha, Girija, Giewont, Whistler and Snow Mystique were transplanted in the first week of October 2016 and 2017 in the mid-hills (Kathmandu valley, 1300 masl) and grown during the winter season with 60X45 cm spacing. Source seed of Snow Mystique was Takii Seed Japan and the rest were Montsanto Seed, India. Crops were fertilized with 200:120:80N.P.K Kg/ha and 15-ton FYM/ha. Insecticide and fungicide were sprayed one time in the early period for crop establishment. The main objective of this experiment was to find out suitable high yielding and insect pest and disease tolerant hybrid cauliflower cultivars for commercial farming in the mid-hills of Nepal. Crops were evaluated with their vegetative, insect pest and disease, yield and farmers' and consumers' response in two consecutive years. Results showed that among the tested cultivars, Barkha was found to be highly uniform, vigorous, less attacked by insect pests and disease, early harvestable (62.7 days after transplanting), efficient per day yield (487.7 kg/ha), preferable average head weight (1039 g), freshness (4.3) and market preference (4.0) as compared to check variety Snow Mystique. On the other hand, Snow Mystique has only yield efficiency (436.2 kg/ha/day), greater insect damage and leaf spot disease, longer days to harvest (101 days), and freshness (3.8), respectively. Hence, Barkha has been selected and recommended for commercial cultivation in the mid-hills of Nepal.
Relative Cost, Profitability and Efficiency among Different Types of Dairy Farms at Bharatpur, Chitwan, Nepal
Authors: Dhakal Shiva Chandra
Published: January 2023

Dairy sector is gradually commercializing and modernizing with the use of improved breeds, processed feeds, cultivated grass, fodders, medicines and additives in Nepal. In this context, this study was designed to evaluate the relative cost, return, resource use efficiency, return to scale and profitability of milk production in different type of dairy farms. Primary data were collected through face-to-face interview using semi-structured interview schedule from a sample of 240 dairy farms selected from simple random sampling technique in 8 wards of Bharatpur Metropolitan City, Chitwan. Data were analyzed using descriptive statistics, cost and profit analysis, linear production function and Cobb-Douglas function. It was found that pure buffalo farms were facing negative profit margin against the profit of Rs. 32565 and Rs. 106627 at cow and mix system of dairy farming, respectively. Average variable cost of per liter milk production was Rs. 93.70, Rs. 54.80 and Rs. 44.73 for buffalo, cow and mix farms, respectively with benefit-cost ratio of 0.99, 1.44 and 1.62 for respective categories of the farms. Green grass, dry fodder, labour, feed, medicines and additives were significantly contributing to milk production in buffalo and cow farms. But, only grass, fodder and labour were contributing to milk production in mix dairy farms. All categories of farms were suffering from decreasing return to scale but they were still profitable over variable cost. Labour was the most contributing factor in all three categories of farms and thus dairy farming seems potential to create productive employment. This is concluded that dairy farming system can be promoted profitably by enhancing the level of use of labour, grass, fodder, medicines and additives.
Factors Determining the Involvement of Women in Income Generating Activities: A Case Study in Pokhara Metropolitan City, Nepal
Authors: Tiwar Surendra
Published: January 2023

Women’s participation in income-generating activities (IGAs) appears to be limited in communities of Nepal owing to a variety of socio-cultural and socio-economic variables. Despite the deliberative efforts by governmental and different developmental agencies for the empowerment of women to be participated actively in income generating activities (IGAs), it is unclear yet what factors stimulate Nepalese women’s engagement in various earning activities. Against this backdrop, the purpose of this study was to investigate the variables that stimulate the participation of Nepalese women in IGAs in the Pokhara Metropolis. For this purpose, a systematic survey form was used to gather data. A total of 130 individuals were interrogated, comprising 65 women engaged in IGAs (selected purposively) and 65 women, who are not involved in IGAs (selected conveniently and purposively) for making the study more comprehensive. A Binary logistic regression model was applied for finding the factors determining the involvement of women in IGAs. The result of the analysis revealed that literacy status, occupational status and monthly income of family affect the women’s involvement in IGAs significantly while age, marital status, caste, family type, number of a family member and age at first marriage do not have any effect on it. The study suggests that it is imperative to make women aware about the importance of involvement in IGAs as this will help them to be self-dependent. The Government of Nepal should focus on women’s education to ensure the necessary knowledge and entrepreneurial skills needed for their effective participation in income-generating activities.

Cast modular trawls and promising methods of making castings for earthmoving and tillage equipment
Authors: Doroshenko Volodymyr , Yanchenko Olexander , Lysyi Mykhailo
Published: January 2023

The development of high-strength cast modular structures for defense or dual-use equipment contributes to the spread of Wartime conditions make research aimed at increasing the country's defense capabilities a priority. It is also necessary to intensify efforts to create materials with increased properties, develop effective methods, technical means and technologies to increase the resource of various equipment and structures, both military and civilian. The development of high-strength cast modular structures for defense or dual-use equipment contributes to the spread of advanced foundry technologies in the field of the defense-industrial complex. In the work, the design of the modular trawl was improved by switching from welded parts to cast modules (from two parts), which by weight are available for assembling these precise cast iron castings in the field, and when manufactured for operation in extreme conditions, their additional strengthening by heat treatment is recommended. A new type of heat treatment is proposed with scientific and technological justification - hardening of cast working bodies to achieve differential hardness of their surfaces, which in conditions of wear will lead to self-sharpening of working bodies of earthmoving and soil processing equipment. Also given are examples of details of modular constructions made by precision casting on patterns that are gasified (Lost Foam Casting, LFC). These examples of castings are, in fact, examples of parts - replacement modules that replace worn parts. Their production is developed using the LFC method, often in a cast state with holes for fastening, they practically do not require mechanical processing. Like the discussed trawls, plows, cultivators, disk-chisel harrows are installed in rows to modern powerful tractors. Teeth for buckets of excavators or feed conveyors are also mounted in rows. The modular structure allows the replacement of damaged modules (as consumables) with new or more advanced ones with minimal delay in the operation of the main supporting structures associated with the drive mechanism or machine.
Intellectualization of traffic management as a means of increasing the efficiency of the city's transport network in emergency situations
Authors: Kashkanov Andriy , Palchevskyi Oleh
Published: January 2023

An assessment of modern trends in the development of intelligent traffic management systems and their role in ensuring the efficiency of the functioning of transport networks was carried out. The processes of introducing technologies for expanding the flow of processed data into existing intelligent transport systems (ITS) that ensure an increase in the speed of information transmission in them have been determined. The classification of information sources that become available when the ITS transitions to the 5G standard and provide a basis for the implementation of technologies for avoiding extraordinary situations in transport networks is given.Existing methods of improving the efficiency of the city's transport network are mainly aimed at ensuring the ability of ITS to predict traffic flows. These include statistical and nonlinear methods, simulation-based methods, artificial intelligence methods, and combined methods. The implementation of these methods is achieved by increasing the information flow coming from the system. A comparison of these methods revealed that they can generally make predictions with high accuracy, however, regardless of the chosen standard, some of them are already at the peak of their potential in terms of application in ITS, and the rest still have room for development.The suitability of the forecasting method for working in real-time conditions is a significant advantage in ensuring effective management of traffic flows, allows to increase the stability of the transport network and the efficiency of the ITS, and has a positive effect on the level of traffic jams, road safety and ecological impact on the environment. The most promising in terms of a quick and flexible solution to an extraordinary situation are models with the use of artificial intelligence or a combination thereof, based on deep learning algorithms, which have proven their importance in predicting the results, making decisions regarding traffic flow forecasts and ensuring the elimination and avoidance of traffic jams based on the passage of vehicles through the intersection depending on the length and duration of the traffic light signals.
Simulation of the wheeled vehicle dynamics during movement over road irregularities
Authors: Nanivskyi Roman
Published: January 2023

The paper outlines the main provisions of the methodology for analytical research of the individual road irregularities impact on the longitudinal-angular oscillations of the wheeled vehicle sprung body. A flat system of three bodies (front, rear bridges, sprung part), whose relative motion is in the vertical plane, was chosen as the physical model for the research. Its peculiarity is that the sprung and unsprung parts interact with each other as elastic shock absorbers with non-linear characteristics of the restoring force. As for road irregularities, it is considered that they are described by smooth functions and the tires are in constant contact with the supporting surface during the wheeled vehicle movement. A mathematical model of the sprung part dynamics was built, which is a second-order nonlinear differential equation with the following feature: its right-hand side is a piecewise continuous function. Based on physically justified assumptions, the differential equation solution was constructed, which describes the relative longitudinal-angular oscillations of the sprung part. It is based on the idea of using: the special periodic Ateb-functions to construct the solution of differential equations with exponential nonlinearity; the construction of asymptotic approximations using the specified functions for new classes of differential equations. Taken together, the above made it possible to obtain differential equations in the standard form, which describe the amplitude-frequency characteristics of the sprung part oscillations. As for the individual irregularities influence on the sprung part dynamics, the amplitude of the longitudinal-angular oscillations of the exit from the irregularity is smaller: at higher vehicle speed; for suspension systems with a regressive change law of the restoring force of elastic shock absorbers; at smaller values of their static deformation for the progressive characteristic of the suspension system (and at larger values for the regressive one). Analytical dependences were obtained, calculations were made and dependences were constructed that describe the amplitude and frequency of these oscillations caused by the irregularities parameters and motion speed.The obtained results can be a basis not only for evaluating the quality of the suspension system, but also for developing algorithms for managing the suspension stiffness in order to improve operational characteristics.

Published: January 2023

The geography of manufacturers of laser devices available for the Ukrainian market is analyzed. The field of application of laser systems at mechanical engineering enterprises is quite wide: heat treatment, welding, cutting, marking, piercing, surfacing and surface alloying. One of the most promising, accurate and productive laser systems at a mechanical engineering enterprise is a laser technological complex. The modern configurations of laser technological complexes, which are used at mechanical engineering enterprises, are considered. A review of sources for generating a beam using a diode laser, as the pumping method most widespread in mechanical engineering, is carried out.The advantages of using laser technological complexes at a mechanical engineering enterprise are considered. The features of the operation of this equipment and potential disadvantages are indicated. We are talking about cutting modes, which simultaneously depend on five or more settings; the quality of oxygen, air or shielding gas used during cutting; ambient temperature during equipment operation; safety features during work. Ways to eliminate potential drawbacks are proposed.Despite the presence of peculiarities of operation of laser technological complexes, they ensure high quality and productivity of production of sheet metal parts in mass production compared to stamping equipment. The laser technological complex provides processing of sheet metals of different thicknesses, different external overall dimensions, within the working table, and different brands of non-ferrous and ferrous metals, which allows it to be used effectively in single production. Also, to the positive qualities of laser installations, you can add insignificant costs for reconfiguring the equipment for the production of new products and the low cost of consumables.
Study of a Cutting Fluid Application System Adaptation on a Bench Milling Machine for an Academic Laboratory Environment
Authors: Talibouya Ba Elhadji Cheikh , Martins Paulo Sérgio , Fernandes Gustavo Henrique Nazareno
Published: January 2023

Abstract: Cutting fluid is a resource that can benefit machining, improving the service life, surface, and dimensional qualities of cutting tools. For the operation of a basic cutting fluid application system, it is necessary to consider the components that store, filter, and induce the flow of the cutting fluid. Some essential components are the reservoir, the filter, and the pump. Aiming to provide better machining conditions, this study presented the proposal for designing and manufacturing a cutting fluid application system for an academic laboratory's bench drill/milling machine. The experimental research characterized the study methodology, in which the system was built with the least possible resources. The main result showed that the system achieved the proposed objective. For pump selection, a system of equations was developed in Microsoft Excel software, which indicated a pressure variation in the flow system of approximately 15 kPa. After the three-dimensional modeling, a script for the manufacture and assembly of the system components was prepared, involving the processes of forming, machining and welding. Adaptations were made to the machine tool, such as the insertion of a limit switch that reduced the longitudinal displacement of the work table by 150 mm. An electronic command system was inserted to control the cutting fluid flow. In the testing phase, positive aspects were observed (reservoir position, absence of leaks, cutting fluid flow, among others) and negative aspects (cutting fluid return paths). Some further improvements proved possible, especially on a machine not designed to have a cutting fluid system.

Tourism potentials of Ulu Apad: a traditional governance system of the original Balinese people in Penglipuran Village
Authors:   Bali Tourism Polytechnic, Suasapha Anom Hery
Published: January 2023

This paper aims to uncover the tourism potential of the Ulu Apad of Penglipuran Village. The Ulu Apad is a traditional governance system that exists only in a Bali Aga Village, believed to be the village of the original Balinese people. Using in-depth interviews and observation, the author extracted and discussed the tourism potentials of the Ulu Apad based on data collected from purposively selected informants. In addition, a literature review was carried out to provide secondary data. The result of the qualitative analysis shows that the Ulu Apad is a potential cultural tourist attraction. The system is so unique that it is different even from fellow Bali Aga Villages, and other customary villages. The system ensured that the most experienced and knowledgeable individuals are chosen to lead the village. Despite its uniqueness, the Ulu Apad has not been utilized as an attractor of tourist visits to the village due to its complexity. The intangible nature of the Ulu Apad means that special effort needs to be put in to ensure its attraction can be enjoyed by the tourist. This article provides insight into how to best utilize the intangible nature of the Ulu Apad as a cultural tourist attraction.

This study aims to analyze the synergy between tourism and agriculture to increase the exchange rate of farmers in the Tabanan Regency area. A literature review approach with a focus on critical review was used in this study. Based on previous research, the study looked at how the Tabanan district's policies affect how tourism and farming work together. The components analyzed are the rationalization and realization of policy implementation related to the analyzed review. This research is a critical literature review to assess, compare, and compile strategy characteristics. The results obtained from the synergy between tourism and agriculture in Tabanan Regency have the potential to be implemented to increase the farmer exchange rate. The idea of mutualism between the two sectors is expected to help tourist villages grow. Improving the size and quality of tourist villages, with the help of local governments, will lead to changes affecting farmers' incomes and exchange rates. They will be able to see the well-being of their farmers. Factors that must be realized to make this synergy concept a success include: 1) the Tabanan Regency Government can facilitate the development of tourist villages; 2) farmers are expected to be open to accepting synergy models of work with the tourism sector, and 3) tourism actors assist farmers in identifying local potentials that have economic value. The policy will likely lead to more and better tourist villages, raising farmers' exchange rates and improving their lives. In conclusion, combining tourism and agriculture makes much sense. The rationalization of policies that local governments and farmers work on can help increase farmers' exchange rates locally and regionally.

Using a literature review methodology, this research investigates the correlation of community-based tourism (CBT) with sustainable development to improve community welfare with a literature review approach. The results in this study are based on previous studies that discuss related topics to the topic being studied. The study showed a correlation between community-based tourism and sustainable development to improve community welfare. The CBT model has a positive effect on managing and empowering local communities while still paying attention to the potential of natural resources, the skills of local communities, the socioeconomic and cultural communities of local communities, and the preservation of the environment to stay sustainable. Applying the CBT model to manage tourism areas is very effective because all activities involve the community in planning, management, and development while still paying attention to local cultural aspects. Tourism policy-makers and those in control of tourist sites should be able to develop and implement a community-based tourism model in order to achieve the Sustainable Development Goals. Thus, directly and indirectly, community-based tourism changes people's perceptions by increasing community participation in tourism activities and increasing the value of people who carry out tourism activities, with implications for improving welfare.
The Reform Measure of the property management system for North Koreans
Authors:   Korea Society of Unification & North Korean Law Studies(North Korean Law Society), Nam Yun-Pyo
Published: January 2023

When a North Korean acquires the right to property in South Korea for reasons stipulated in the Act on Special Cases for Inter-Korean Families, such as inheritance and bequest, a property manager is appointed to manage the inherited and bequeathed property of the North Koreans. At the time of legislation, the North Korean property management system used the absentee property management system as the main framework, but there is a significant difference from the absentee property management system in terms of purpose and content.
To this end, I offer the following opinion.
① Regarding the interpretation of “confirmation of acquisition of rights” as the time and reason for appointing a property manager, in case of inheritance and bequest, the time of death of the deceased (the testator) shall be the standard, but if there was inheritance under false pretenses, North Korean residents exercise their rights and make a judgment It should be based on the time when the provisional execution was confirmed, and if the right was actually acquired through provisional execution, it should be based on the time of provisional execution.…
VERSO L’INCERTEZZA DELL’ABITARE. LE SOLUZIONI ABITATIVE DI EMERGENZA NEL POST-DISASTRO DELL’APPENNINO CENTRALE (2016-2017)
Authors: DELLA VALLE CLAUDIA
Published: January 2023

Far beyond the physical consequences of the impact, a socio-natural disaster raises important issues about the territories and the affected population’s future, mainly if it involves marginal areas such as those of the central Apennines, hit by a long seismic sequence between 2016 and 2017. Proper housing emergency management, capable of offering timely and adequate responses in the immediate emergency, above all in the medium-long term, is both a challenge and a crucial point for any post-disaster policy. This research proposes an analysis of Soluzioni Abitative di Emergenza (SAE) as the institutional response to the housing emergency caused by the 2016-2017 earthquakes: temporary and prefabricated houses installed in the municipalities affected by the disaster, which will offer housing to the displaced population until the end of the reconstruction. Through ethnographic methodological tools and discursive interviews, the research investigates temporary and emergency living and highlights that the relationship between the inhabitants and space, especially the domestic one, is complex, articulated and sometimes contradictory.

Published: January 2023

Reuse of elements from existing ontologies in the construction of new ontologies is a foundational principle in ontological design. It offers the benefits, among others, of consistency and interoperability between such knowledge structures as well as sharing resources. Reuse is widely found within important collections of established ontologies, such as BioPortal and the OBO Foundry. However, reuse comes with its own potential problems involving ontological commitment, granularity, and ambiguity. Guidelines are proposed to aid ontology developers and curators in their prospective reuse of content. These guidelines have been gleaned over years of practice in the ontology field. The guidelines are couched in experiential reports on designing and curating particular ontologies (e.g., EXACT and EXACT2) and using generally accepted approaches (e.g., MIREOT) in doing so. Various software tools to assist in ontology reuse are surveyed and discussed.

BACKGROUND: Complete atrioventricular block is most commonly caused by age-related degeneration and fibrosis in the cardiac conduction system and is called primary idiopathic complete atrioventricular (iCAVB). Although many factors affect this situation, which increases with age in the cardiac conduction system, the relationship between whole blood viscosity (WBV) and iCAVB has not been clarified until now. In this study, we aim to reveal the relationship between iCAVB and WBV. METHODS AND RESULTS: 141 patients with dual-chamber permanent pacemaker implanted for iCAVB and 140 age- and sex-matched subjects were included in this study. The WBV values of the study groups were compared in both high shear rate (HSR) and low shear rate (LSR). Both WBV at HSR and WBV at LSR were significantly higher in the iCAVB group compared to the control group (16.11 [15.14–16.89] vs 14.40 [13.62–15.58]; 39.82 [17.43–55.23] vs 1.38 [–13.14–26.73]; p < 0.001, respectively). The patient population was followed up for an median of 38 months for all-cause mortality. Higher mortality rates were found in higher WBV at HSR and WBV at LSR (p < 0.001,for both). CONCLUSIONS: In this study, WBV was found to be an independent predictor for iCAVB, and in these patients WBV was associated with poor clinical outcomes.

OBJECTIVE: Our aim was to investigate the correlation between biomarkers and VTE and the predictive value of D-dimer for VTE in hospitalized COVID-19 patients. METHODS: Complete blood count, inflammatory and coagulation biomarkers at admission were collected. VTE was defined as diagnosed pulmonary embolism or deep vein thrombosis. Events were defined as in-hospital death or ICU admission. Predictors of VTE were identified with Pearson prediction models. A ROC curve was constructed to assess the predictive value of D-dimer. RESULTS: 1651 participants were included, 111 VTE were identified. Events incidence was higher in the VTE group (49.5% vs 28.2%, p < 0.001). Neutrophil-lymphocyte ratio (NLR, 0.001; 95% CI 0.000–0.002; p 0.019) and D-dimer (0.00005; 95% CI 0.00002–0.00008; p < 0.001), Geneva score (0.026; 95% CI 0.012–0.040; p < 0.001) and Wells score (0.047; 95% CI 0.033–0.061; p < 0.001) were associated with VTE. D-dimer had a goor predictive value for VTE (ROC area 0.85, 95% CI 0.816–0.893), with an optimal cut-off value of 2677μg/L (Youden index of 0,602). CONCLUSIONS: Among coagulation biomarkers D-dimer had the best predictive value for VTE, but higher cut-off values should be used in COVID-19.

BACKGROUND: Cervical lymphadenopathy can be benign or malignant. Its accurate diagnosis is necessary to determine appropriate treatment. Ultrasound-guided core needle biopsies (US-CNBs) are frequently used as a percutaneous sampling approach. OBJECTIVES: Our aim was to identify the efficacy and safety of US-CNBs in 125 patients with cervical lymphadenopathy and clinically suspected head and neck cancer during the COVID-19 pandemic with limited surgical resources. METHODS: US-CNBs of pathological lymph nodes were performed in 146 lymph nodes on 125 patients. Biopsies were performed ultrasound-guided with a reusable gun core biopsy system and a 10-cm-long 16-G needle. Standard of reference for the histological findings were panendoscopy, clinical and sonographic follow-up, surgical biopsy or a repeat US-CNB. RESULTS: Adequate material for histologic diagnosis was obtained in 111 patients (89%), of these 83 patients (75%) were diagnosed as malignant, whereas benign lymphadenopathy accounted for 28 patients (25%). Therefore, US-CNB was able to identify malignant or benign lymphadenopathy with an overall accuracy of 88% and 90%, respectively. CONCLUSIONS: Percutaneous US-CNB is a safe and effective alternative to surgical biopsy in the management of cervical lymphadenopathy in patients with clinically suspected head and neck cancer in a setting with limited resources.

Background: Cardiac involvement in idiopathic inflammatory myopathy (IIM or “myositis”) is associated with an approximate 4% mortality, but standardised screening strategies are lacking. Objective: We explored a multimodality screening on potentially reversible cardiac involvement –i.e. active (peri)myocarditis –in newly diagnosed IIM. Methods: We included adult IIM patients from 2017 to 2020. At time of diagnosis, patients underwent cardiac evaluation including laboratory biomarkers, electrocardiography, echocardiography, and cardiac magnetic resonance imaging (CMR). Based on 2019 consensus criteria for myocarditis, an adjudication committee made diagnoses of definite, probable, possible or no (peri)myocarditis. We explored diagnostic values of sequentially added diagnostic modalities by Constructing Classification and Regression Tree (CART) analysis in patients with definite/probable versus no (peri)myocarditis. Results: We included 34 IIM patients, in whom diagnoses of definite (six, 18%), probable (two, 6%), possible (11, 32%), or no (peri)myocarditis (15, 44%) were adjudicated. CART-analysis showed high-sensitivity cardiac troponin T (cut-off value < 2.3 times the upper limit of normal (xULN)) ruled out (peri)myocarditis with a sensitivity of 88%, while high-sensitivity troponin I (cut-off value > 2.9 xULN for females and > 1.8 xULN for males) ruled in (peri)myocarditis with a specificity of 100%. Applying high-sensitivity cardiac troponins with these cut-off values in a diagnostic algorithm without and with a CMR to the total population of 34 patients demonstrated a diagnostic accuracy for a clear diagnosis of probable/definite or no (peri)myocarditis of 59% and 68%, respectively. Conclusions: A diagnostic algorithm for detection of (peri)myocarditis in adult IIM may consist of sequential testing with high-sensitivity cardiac troponins and CMR.

Synthesis of cobalt aluminate was achieved by using the peel extracts of Citrus family species. The peel extracts of lemon, orange and mandarin were used as capping agent in experimental step. These peels were extracted through varied solvents including water, ethanol and methanol. In this regard, the efficacies of the peel type and the extraction liquid were surveyed in the study, using a co-precipitation technique in the synthesis of CoAl2O4 spinel. Samples compared in different parameters were subjected to a range of analyses consisting of colorimetry, X-Ray Diffraction, Scanning Electron Microscope and thermal examinations. The minimum b* value was reached as –14.23 in the sample with a capping agent provided by the orange peel extract, extraction liquid of which is water. The results denoted successful crystal structure scores and single-phase CoAl2O4 formation as well as the occurrence of a double-phase configuration. The highest XRD score of 83 was obtained for CoAl2O4. Considering SEM results, the lowest and highest particle size distributions were found between 100–150 nm and 350–800 nm, respectively. In the research, cobalt aluminate synthesis was carried out by means of modifying agents prepared with the peels of Citrus family species using different solvents.

BACKGROUND: In today’s fast-paced world, both men and women have to be equally competent to handle their responsibilities in order to look after their family members and children. In this pace of competency women tend to forget to take care of their own health and face many health issues, including pelvic floor dysfunction. OBJECTIVE: This study aimed to analyse the prevalence rate of pelvic floor dysfunction among the working women in regards to their age and body mass index as well as their quality of life. METHODS: One hundred sixty one post-partum working female participants from the medical fraternity were involved in this study after their consent was obtained. Pelvic floor muscle strength was assessed and their quality of life measured using King’s health questionnaire. RESULTS: There was a strong correlation between the pelvic floor muscle dysfunction and its impact on the quality of life among the females with increasing age. Significant statistical significant difference of P(<0.0001) was noted. CONCLUSION: Pelvic floor dysfunction among females has a direct impact on their quality of life.

BACKGROUND: The domain of faculty internationalization is under-researched, especially in the context of China. Extant research does not lend itself to applied insight, despite offering theoretical and methodological precision. OBJECTIVE: Based on the motivational systems theory, this study developed a parsimonious measure of overall faculty motivation (including capacity beliefs, context beliefs, emotions, and goals) and investigated its effect on work performance through the mediating effect of engagement in internationalization among faculty in a Chinese research-centric university. METHODS: Data of 229 faculty members were analyzed using a structural equation modeling approach. RESULTS: Faculty responses indicated that: i) the second-order overall faculty motivation scale is superior to individual items in measuring the effect of overall faculty motivation on faculty engagement and work performance; ii) overall faculty motivation positively influences faculty engagement; iii) overall faculty motivation promotes work performance; iv) faculty engagement mediates the relationship between overall faculty motivation and work performance. CONCLUSION: Faculty responses indicated that the effect of the second-order overall faculty motivation construct is superior to individual items in terms of its effect sizes on faculty engagement and work performance. More so, the measurement model showed that overall faculty motivation exerts a direct and indirect (faculty engagement) positive effect on work performance. Chinese universities should align the goals, capacity belief, context belief, and emotions of faculty with national/institutional goals to yield superior engagement for better performance.
