Open scientific content search tools for research and education

Introduction. The concept of open science, actively promoted in recent decades, as well as technological innovations, make the culture of information retrieval a significant element in the development of the information society, which has a significant impact on scientific activity, education, management, social processes, etc. Indicators of the level of culture of information retrieval are knowledge of basic methods and means of obtaining information, including skills and abilities to work with information resources and search engines. The culture of information retrieval helps improve the quality of information extraction from increasingly large open information arrays. Open tools for searching scientific content are the most important, but require training during operation, they are components of the global market of information resources and services, allowing the selection of relevant information from large data sets in accordance with user requests.Purpose setting. The study sets the task of studying the applicability of individual scientific search systems (Google Scholar, Semantic Scholar, Internet Archive Scholar and BASE) for information searching when conducting research and in educational processes, developing competencies to improve the level of information culture of specialists in the field of library and information sciences.Methodology and methods of the study. The research was carried out using comparative and system analysis methods, mathematical methods for processing statistical data, and content analysis of documentary sources of information. The methodological basis was practice-oriented and competency-based approaches aimed at developing the professional skills of librarians and library scientists in searching for digital content and using open access resources.Results. The analysis made it possible to draw conclusions about the capabilities of search systems, methods for retrieving information and the specifics of the reflection of publications in them, as well as the most acceptable conditions for information retrieval in the field of «library and information sciences», which makes it possible to more rationally use the potential of systems and quickly obtain complete and relevant scientific information on the topic.Conclusions. The results of the study add a new dimension to our knowledge of scientific search engines. The study presents evidence that Google Scholar is a powerful tool for searching Russian literature in the field of library science in terms of articles from scientific journals, as well as detecting a limited volume of some other types of publications with the ability to evaluate with Google Scholar Metrics. It is concluded that Google Scholar, Semantic Scholar, Internet Archive Scholar and BASE, despite being positioned as effective tools for searching scientific information in various disciplines, require caution in use, because these systems cannot guarantee comprehensive results and are not complete sources of bibliographic data, but can be considered in conjunction with other resources, taking into account the availability of advanced search engines and additional services. Knowledge of scientific search engines contributes to improving the culture of information retrieval, the culture of users, their qualifications and professionalism.

Photovoltaic-Based q-ZSI STATCOM with MDNESOGI Control Scheme for Mitigation of Harmonics

Static compensators (STATCOMs) are often used in distribution systems to enhance power quality. There is a need to enhance the performance of STATCOM to optimize its utilization and facilitate the provision of additional ancillary services. This paper employs the multilayer discrete noise-eliminating second order generalized integrator (MDNESOGI) to regulate the quasi-impedance source inverter (qZSI)-STATCOM for power exchange with the grid. Compared to conventional second-order generalized integrator (SOGI), MDNESOGI exhibits a higher capability for rejecting DC offset. In instances of abnormal grid operation or system malfunction, the inclusion of DC rejection capability enhances the robustness and reliability of the system. The suggested control algorithm only requires two integrators, three mathematical operators, and a damping factor, making it far easier to implement than transformation-based methods. The distorted load current is broken down into its active and reactive components using this control mechanism. The reference currents are then calculated by multiplying these parts by their corresponding voltage standards. The DC offset is reduced and transient oscillations in the weight component are eliminated by adjusting the damping factor. The suggested algorithm effectively handles power quality tasks like (a) reducing harmonic distortion, (b) compensating for reactive power, (c) adjusting for power factor, and (d) balancing the load under different conditions in the distribution system. The experimental study results are used to examine the stability of the proposed control scheme in both static and dynamic scenarios. In addition, a comparison to traditional methods is provided to demonstrate the new method’s superiority. Experimentation results show that the suggested controller is superior to its contemporaries in all scenarios where power quality is a factor, meeting the IEEE standard requirements.

A life in the surf zone: Age and feeding habits of the pompano (Trachinotus ovatus, Linnaeus, 1758) on the beaches of the Gulf of Cádiz (south-west Iberian Peninsula).

Surf zones are crucial habitats for many fish species, where they spend the initial stages of their lives, finding food and shelter. One such species is the pompano (Trachinotus ovatus). The aim of this study was to examine the age and diet of the pompano within the surf zone, along with any potential variations in the environment. The average size of the specimens was 10.61 ± 4.91 cm. The length-weight relationship was total weight (TW) = 0.0136*total length (TL)2.8512 (parameter a: 95% C.I.: 0.0130-0.0142 and parameter b: 95% C.I.: 2.8318-2.8705). The most abundant age classes were 0+ and 1+, making up 97% of the captured specimens, with significant differences in the abundance of age classes depending on the time of the day and season. The pompano primarily fed on clupeiforms, copepods, and mysids, with significant variations in diet based on the time of the day, season, and size of the specimens. This study contributes new information about the use of the surf zone by T. ovatus in its early years of life, underscoring the importance of these areas and their role as an additional ecosystem service.

Sleep, Anxiety, Somatization, Quality of Life, and Resilience in Pediatric Patients With Eosinophilic Esophagitis.

Emerging evidence suggests a high burden of psychosocial comorbidities in patients with eosinophilic esophagitis (EoE), although factors associated with this burden have not been explored. We aimed to increase understanding of the psychosocial burden of EoE and assess factors that are associated with disease burden. We conducted a cross-sectional study of patients with EoE (n = 87) recruited from a single-center, multidisciplinary pediatric eosinophilic gastrointestinal disorders clinic (2019-2021). Participants (aged 8-18 years) completed validated assessments during routine clinic visit to assess EoE symptoms (Pediatric Eosinophilic Esophagitis Symptom Score version 2.0), quality of life (Pediatric Quality of LIfe- Eosinophilic Esophagitis), anxiety state and trait (State-Trait Anxiety Score for Children), somatization (Child Somatic Symptoms Inventory 24), sleep disordered breathing (Pediatric Sleep Questionnaire) and, in a subset (n = 35), resilience (Connor Davidson Resilience Scale). Clinical and demographic data were collected. Participants were at a mean (SD) age of 12.8 (3.1) years, and 26% (n = 23) were female. Shorter disease duration (6-12 months) was associated with higher symptom burden ( P = 0.03), somatization ( P < 0.01), and anxiety (State-Trait Anxiety Score for Children Trait P < 0.01) scores. Participants with neurodevelopmental comorbidities had higher anxiety trait, somatization, sleep disordered breathing, and lower quality of life ( P < 0.01 for all). Symptom burden was significantly associated with increased somatic symptoms (adjusted β [aβ] = 0.34; 95% confidence interval 0.23-0.45) and decreased quality of life (aβ = -0.42; 95% confidence interval -0.59 to -0.25) but not state anxiety, trait anxiety, or disordered sleep breathing. Pediatric patients with a recent diagnosis of EoE can experience higher EoE symptoms, somatization, and anxiety when compared with those with a longer-standing diagnosis. Patients earlier in their diagnosis and with neurodevelopmental disorders may experience increased somatization and anxiety that may warrant additional support services.

Association of Designated Pediatric Trauma Center and Outcomes of Severely Injured Children Who Were Mechanically Ventilated and Underwent Tracheostomy: A Propensity-Matched Analysis.

The purpose of the study is to examine the outcomes of care delivered at the pediatric trauma center (PTC) in severely injured children who were intubated, mechanically ventilated, and underwent tracheostomy. The study data were obtained from the Trauma Quality Improvement Program database for the calendar years 2017 to 2019. All children aged ≤17 years who sustained severe injury, required intubation and mechanical ventilation for more than 96 hours, and underwent tracheostomy were included in the study. Patients' characteristics, injury severity, and outcomes were compared between the care provided at the PTCs (level I or level II) and nonpediatric trauma centers (NPTCs). The propensity score matching methodology was used to perform the analysis. All P values are 2-sided, and a P value of <0.0.5 is considered statistically significant. Of 2164 patients who were qualified for the study, 1288 (59%) of the patients were treated at PTCs, and 876 (40.5%) of the patients were treated at NPTCs. Propensity matching created 876 pairs of patients. There were no significant differences found between the 2 groups on patients' characteristics except for age. Patients who were treated at PTCs had a median age of 14 (10-16) versus 15 (11-17) years ( P < 0.001) when compared with care provided at NPTCs. A longer hospital stay was found in the PTC group when compared with the NPTC group (24 [23, 25] vs 22 [21, 24], P = 0.008). Patients who were treated at PTC were found to have significantly less sepsis occurrence (0.9% vs 2.2%), and a higher proportion of patients were discharged home without needing additional support (26.2% vs 18.5%). Care at the PTC was associated with a lower occurrence of sepsis complications. A higher number of patients were discharged home without additional services when the care was provided at PTC.

Commercial provider staff experiences of the NHS low calorie diet programme pilot: a qualitative exploration of key barriers and facilitators

BackgroundThe National Health Service Type 2 Diabetes Path to Remission programme in England (known as the NHS Low Calorie Diet programme when piloted) was established to support people living with excess weight and Type 2 Diabetes to lose weight and improve their glycaemic control. A mixed method evaluation was commissioned to provide an enhanced understanding of the long-term cost effectiveness of the pilot programme, its implementation, equity and transferability across broad and diverse populations. This study provided key insights on implementation and equity from the service providers’ perspective.MethodsThirteen focus groups were conducted with commercial providers of the programme, during the initial pilot rollout. Participants were purposively sampled across all provider organisations and staff roles involved in implementing and delivering the programme. Normalisation Process Theory (NPT) was used to design the topic schedule, with the addition of topics on equity and person-centredness. Data were thematically analysed using NPT constructs with additional inductively created codes. Codes were summarised, and analytical themes generated.ResultsThe programme was found to fulfil the requirements for normalisation from the providers’ perspective. However, barriers were identified in engaging GP practices and receiving sufficient referrals, as well as supporting service users through challenges to remain compliant. There was variation in communication and training between provider sites. Areas for learning and improvement included adapting systems and processes and closing the gap where needs of service users are not fully met.ConclusionsThe evaluation of the pilot programme demonstrated that it was workable when supported by effective primary care engagement, comprehensive training, and effective internal and external communication. However, limitations were identified in relation to programme specifications e.g. eligibility criteria, service specification and local commissioning decisions e.g. pattern of roll out, incentivisation of general practice. A person-centred approach to care is fundamental and should include cultural adaptation(s), and the assessment and signposting to additional support and services where required.

A Delphi consensus study to determine the workload components and activity standards of dietitians in South Africa’s central and tertiary public hospitals

BackgroundThe global Human Resources for Health (HRH) strategy emphasizes the need to invest in HRH to meet population needs and improve the provision of quality health care services. In South Africa, dietitians are recognized as registered professionals who provide nutrition services. In this paper, we used 2 key steps (3 and 4) of the eight step World Health Organization (WHO) Workload Indicators of Staffing Need (WISN) methodology to determine the workload components and activity standards for dietitians at South African central and tertiary public hospitals.MethodsAll (9) provincial nutrition managers (phase one) and 21 out of a total 22 head dietitians at central and tertiary public hospitals (phase two) participated in an online survey. In phase one, the provincial managers provided the job descriptions (JDs) of dietitians in their provinces, and the JDs were analyzed to determine the baseline workload components. In phase two, dietitians participated in a multi-stage Delphi process to reach consensus on workload components and activity standards. Consensus was deemed to be agreement of 70% or more, while the median of participants’ responses was used to obtain consensus on the activity standards.ResultsThe JDs of dietitians were a useful baseline for the consensus exercise as there were no other suitable source documents. The response rate was 100% for all three rounds of the Delphi survey. Dietitians reached agreement (consensus ≥ 70%) on 92% of proposed workload components and activity standards. Following the removal of duplicate and certain administrative activities, a total of 15 health, 15 support and 15 additional service activities with aligned activity standards resulted from the consensus exercise.ConclusionThe Delphi technique was a suitable method for reaching agreement on workload components and activity standards for dietitians at South African central and tertiary public hospitals. The findings from this study can now be used to compile a standardized list of workload components and activity standards and ultimately to determine dietetic staffing needs for the central and tertiary public hospital level of care.

Factors associated with obtaining prescribed safer supply among people accessing harm reduction services: findings from a cross-sectional survey

BackgroundWith growing rates of unregulated drug toxicity death and concerns regarding COVID-19 transmission among people who use drugs, in March 2020, prescribed safer supply guidance was released in British Columbia. This study describes demographic and substance use characteristics associated with obtaining prescribed safer supply and examines the association between last 6-month harm reduction service access and obtaining prescribed safer supply.MethodsData come from the 2021 Harm Reduction Client Survey administered at 17 harm reduction sites across British Columbia. The sample included all who self-reported use of opioids, stimulants, or benzodiazepines in the prior 3 days (N = 491), given active use of these drugs was a requirement for eligibility for prescribed safer supply. The dependent variable was obtaining a prescribed safer supply prescription (Yes vs. No). The primary independent variables were access to drug checking services and access to overdose prevention services in the last 6 months (Yes vs. No). Descriptive statistics (Chi-square tests) were used to compare the characteristics of people who did and did not obtain a prescribed safer supply prescription. Multivariable logistic regression models were run to examine the association of drug checking services and overdose prevention services access with obtaining prescribed safer supply.ResultsA small proportion (n = 81(16.5%)) of the sample obtained prescribed safer supply. After adjusting for gender, age, and urbanicity, people who reported drug checking services access in the last 6 months had 1.67 (95% CI 1.00–2.79) times the odds of obtaining prescribed safer supply compared to people who had not contacted these services, and people who reported last 6 months of overdose prevention services access had more than twice the odds (OR 2.08 (95% CI 1.20–3.60)) of prescribed safer supply access, compared to people who did not access these services.ConclusionsOverall, the proportion of respondents who received prescribed safer supply was low, suggesting that this intervention is not reaching all those in need. Harm reduction services may serve as a point of contact for referral to prescribed safer supply. Additional outreach strategies and service models are needed to improve the accessibility of harm reduction services and of prescribed safer supply in British Columbia.

Assessing the Benefits and Downsides of Physician Review Websites to Plastic Surgeons: A Cost-Benefit Analysis.

Patients often evaluate the reputations of plastic surgeons based on their performances on physician review websites. This article aims to compare rating methodologies and conduct a cost-benefit analysis of physician review websites to further understand how plastic surgeons and their patients can utilize review websites to inform their practice and care. A review of online literature, blogs, and 17 of the most common physician review websites was conducted to identify information on review website methodology, cost, and benefits most pertinent to plastic surgeons and their patients. Physician review websites utilize various combinations of physician-related and unrelated criteria to evaluate plastic surgeons. Across 17 reviewed platforms, most (71%) utilize star ratings to rate physicians, 18% require an appointment to conduct a review, and 35% feature search engine optimization. Many websites (53%) allow physicians to pay for benefits or extension packages, with benefits offered including advertising, search engine optimization, competitor blocking, social media marketing, consultant services, and data analytics. Competitor blocking was provided by the most number of websites who offered additional services for pay (78%). Appointments are not required to post physician reviews on many review websites, and many websites allow physicians to purchase packages to enhance their search engine optimization or consumer reach. Accordingly, plastic surgeons' reputations on review websites may be influenced by factors extraneous to actual patient care. Patients and physicians should be cognizant that physician review websites may not be reflective of factors related to quality of patient care.

Improving Broadcast System of Integrated Satellite-Terrestrial Network-based on Enhanced Ant colony Optimization

With the use of seamless high-speed worldwide network connectivity in future, it is anticipated that the integrated satellite-terrestrial network (ISTN) will be a possible option. Due to the inadequacy of topological data and the close coupling of data and control planes, deploying optimized rules on routers is difficult. The important factors in ISTN networks are routing rules and policies, link failure, and high-bandwidth communication. Software-defined networking (SDN) is an open innovation approach that enables programmability from a central location. The controller handles the complexity of the network, whereas the infrastructure layer devices relay the packets. Thus, we investigated the broadcast by dynamically adjusting routes for fault tolerance and energy efficiency of the ISTN using distance between nodes. In addition, using dynamic source routing, this study examines the competence functions of all managing nodes in a network. The routing design is distributed among all nodes to create numerous collective paths. For LEO satellite networks, the ant colony optimization-based routing algorithm is an improved version that considers the probability of faults and low-energy consumption. The proposed simulation ensures a seamless transition in the event of failures and avoids the requirement for an additional coordination service.

Adverse Childhood Experiences and Illegal Drug Use Among College Students: Findings from a French Sample.

While studies have demonstrated the negative impact of adverse childhood experiences (ACEs) on lifelong health, less is known about the relationship between ACEs and illegal drug use. Thus, the objective of the study was to examine the relationship between ACEs and illegal drug use among college students. French college students between 18 and 30 years enrolled in a university cohort study were eligible for inclusion. Multivariate logistic regression models were conducted for each drug. Among the sample (n = 1,157), 30.6% had no ACE exposure, 29.6%, 19.2%, and 20.7% had 1, 2 and ≥ 3 ACEs, respectively. Students with ACEs had a higher likelihood of using illegal drugs (p = 0.0067). After controlling for potential confounders, having ≥ 3 ACEs increased the risk of lifetime use of multiple drugs (aOR:10.9; 95% CI: 4.6-26.0), stimulants (aOR: 3.6; 95% CI:1.7-7.7), hallucinogens (aOR: 2.0; 95% CI: 1.1-3.5), cannabis (aOR: 4.7; 95% CI: 2.7-8.0), and risky illegal drugs (e.g., higher lifetime frequency drug use) (aOR: 2.9; 95% CI: 1.5-5.8). Estimates for illegal drug use were highest with parental substance use (aOR: 2.6; 95% CI; 1.5-4.4), sexual abuse (aOR: 2.3; 95% CI; 1.4-3.8), and divorce (aOR: 1.9; 95% CI: 1.3-2.7). ACEs increase the risk for lifetime illegal drug use and risky drug use in a dose-respondent fashion. These findings suggest that university students with higher levels of ACEs may benefit from additional support and services from clinical practitioners and university administrators.

Mobility-as-a-Service (MaaS) and sustainable urban mobility in the development of the European museum business: a case study of Spain

The purpose of this article is to analyze the current state of museums in Spain through the prism of the dynamic development of innovative technologies in society. The article reveals the tourist preference for Mobility-as-a-Service (MaaS), which is a single digital travel platform that integrates all the necessary information. An important contribution to sustainable urban mobility is public transport, shared bike, shared e-moped, and shared car. These components, coupled with digital services offering route information to museums, information about museums, booking and purchasing tickets to museum complexes, form the basis and are the main MaaS bundle attributes. Methodology is based on scientific and special research methods. The methods used were analysis, synthesis, systematization, classification, generalization of economic and methodological sources. The authors examined the key properties of the processes of formation and development of museums as one of the most representative manifestations of the cultural heritage of society. The article addresses important issues of the tourism sector through the prism of the European museum sector, analyzing: historical aspects of the development of European social institutions of museum affairs, statistical indicators of the number of museums in European countries, emphasizing their key role in the dynamic development of tourism. To thoroughly analyze the development of European museums, the author examines one of the exemplary examples of creating a successful museum sector in Spain. It is proved that the effectiveness of the museum sector development largely depends on its integration into the socio-economic life of the country, accessibility for all social groups of visitors, sustainable development, available additional services, and a modern website with information about the museum.

The role of syndromic knowledge in Ethiopian veterinarians' treatment of cattle.

Veterinarians play a significant role in the treatment and prevention of livestock diseases at the farm level, safeguarding public health and ensuring food safety. In sub-Saharan Africa, access to quality veterinary services is a major challenge for livestock farmers due to the low number of publicly employed veterinarians, underfunding and privatisation of veterinary services. Low investment in veterinary services and infrastructure, including a lack of laboratories for diagnosis, has made veterinarians rely on their experience and knowledge of cattle disease symptoms developed over years of practice to diagnose and treat cattle diseases. A cross-sectional survey using a role-play approach was used to collect data on knowledge regarding cattle diseases among veterinarians in veterinary clinics and private practices in Addis Ababa, Oromia and Adama regions in Ethiopia. Veterinarians were given a number of disease scenarios based on "fictive disease symptoms" that are commonly manifested in a sick cow and asked to identify the disease what personal biosecurity they would use, diagnostic tests they would perform, treatments they would prescribe, treatment costs, and additional services and inputs they would recommend to the farmer. The results show that veterinarians could identify endemic cattle diseases through symptoms. The majority of veterinarians did not find it important to report notifiable diseases, a behaviour which could hamper disease surveillance and outbreak response. The advice and services the veterinarians said they would offer and recommend to farmers included improvement in feeding, vaccination, use of artificial insemination, and adoption of farm biosecurity measures that can reduce disease prevalence, and improve food safety, animal health and welfare. Low use of personal protective equipment and other protective biosecurity measures among veterinarians could expose them to zoonotic diseases. The study concludes that there is a need for increased funding for continuous training, improved access to animal health-related information, and investment in infrastructure such as laboratories to enable veterinarians to deliver quality animal health services.

Дослідження та удосконалення конкурентних переваг підприємства

In the scientific literature, there is a variety of approaches to determining the essence of competitive advantages. It is well-known to define competitive advantages as characteristics, consumer properties of a product or brand that give an enterprise an advantage over its competitors. This advantage can be achieved by providing consumers with greater benefits, whether through the sale of more affordable products or the offer of high-quality goods with additional services, at comparatively higher prices. Ensuring competitive advantages is an important aspect of strategic enterprise management in a competitive environment. The variety of approaches to defining the essence of this category testifies to its multifaceted nature. The formation of competitive advantages at the enterprise can be achieved by rationalizing the cost of production, a high level of product differentiation, reasonable market segmentation, the introduction of innovations and a rapid response to market needs. Significant factors for ensuring competitive advantages at the enterprise are also an increased level of labor productivity and personnel qualifications, quality and technical level of manufactured products, managerial expertise and strategic thinking at all levels of management. Important factors influencing competitiveness are also warranty and post-warranty service, advertising, the manufacturer’s image and the market situation, including fluctuations in demand. The process of ensuring competitive advantage requires the enterprise to identify social interaction in the market environment, in particular, responding to criticism, the ability to learn, communicate and maintain connections with stakeholders. This creates the prerequisites for the effective development of the enterprise. In the process of ensuring competitive advantage, it is important to focus on innovations that allow you to gain a competitive advantage, such as new technologies, changes in customer demands, production costs and component availability.

The method of assessing the efficiency of tunneling management in trunk networks

The article deals with the method of evaluating the effectiveness of tunneling management in trunk networks with a focus on improving efficiency and optimizing data transmission. The relevance of creating a tunneling management technique in the context of growing traffic volumes and expanding the functionality of IP/MPLS networks is substantiated. It is noted that traditional control methods may be ineffective in the given environment, and the use of specialized models of network construction is a key factor for optimal use of tunnel resources. The main requirements for the trunk network technology are high bandwidth, speed of information transfer and scalability. The current state of the market and the needs of users require access to integrated network services, and the organization of virtual private networks, the provision of intelligent services. The growing demand for additional services implemented on top of simple IP access requires the development of backbone network architectures with virtually unlimited scaling capabilities, increased traffic processing speed, and unprecedented flexibility in terms of the organization of additional services. The MPLS technology allows for network integration, due to which service providers will not only be able to save the means invested in asynchronous transmission equipment, but also get additional benefits from the compatible use of protocols. It is proposed to use a specialized model to determine and optimize tunnel resources aimed at maintaining a high level of service quality. It is shown that with an increase in the load with an unchanged number of nodes, the time the packet stays in the tunnel increases, since the load served by each node increases, and therefore the total time the packet stays in the tunnel.

The impact of the health microinsurance M-FUND on the utilization of health services among migrant workers and their dependents in Thailand: A case-control study

BackgroundEven though Thailand has launched multiple migrant health policies, migrants still face various barriers in accessing health care. To some extent, these barriers may be reduced by health microinsurance. The M-FUND is a low-cost, not-for-profit health protection scheme for migrant workers in Thailand, created by Dreamlopments Social Enterprise and Foundation to support sustainable access to quality healthcare services for migrants. We aimed to investigate the impact of the M-FUND on utilization of health services. MethodsOver a period of three months, we conducted quantitative face-to-face interviews with 408 M-FUND members, and 452 age, sex and location matched non-member controls in Tak Province, Thailand. We compared utilization of health services between members and non-members using logistic regression controlling for a number of socio-demographic variables and variables related to migration such as years in Thailand, legal status, etc. FindingsM-FUND members were more likely to have utilized outpatient services (adjusted odds ratio: 1·74, 95 % confidence interval: 1·24–2·44), inpatient services (2·96, 1.11–7·92), and emergency care (1·89, 0·78–4·56), although the latter was not statistically significant. Members were more likely not to have purchased medicines over-the-counter (1·67, 1·22–2·27) than non-members. Members were also more likely to have utilized any additional specific service during a consultation (2·31, 1·49–3·58) including any type of imaging method (2·62, 1·29–5·29) and blood tests (1·64, 0·99–2·71). There were some differences between men and women, but most were not statistically significant. InterpretationThe M-FUND health microinsurance was positively associated with the utilization of all major types of health services among migrant workers and their dependents in Thailand. For migrants, particularly vulnerable migrant workers and their dependents, the M-FUND appears to be a good approach to reducing barriers to health care. This study of the impact of health microinsurance for migrants provides important information for policy and program planners in the field of migrant health. However, more research is needed on health microinsurance schemes for migrants in different settings and for other underserved communities as well as the sex-specific impact on health service utilization.

EVALUATION OF A PATIENT WITH LUNG CANCER IN A PALLIATIVE CARE CENTER IN ACCORDANCE WITH THE ROPER, LOGAN, TIERNEY NURSING MODEL: A CASE REPORT

Lung cancer creates a significant burden on the health care system in the world, with its high incidence, the need for advanced technology in diagnosis and treatment, and the need for additional health services. Supporting the patient's care and independence and finding solutions to existing problems in the rapidly increasing number of terminal stage patients with lung cancer in the world and in our country require a very comprehensive approach. Care, one of the most important functions of nursing, is a concept that should not be ignored in nursing practices in the rapidly changing and developing field of health. The care plan should be designed with an individualized nursing care philosophy, taking into account individual differences, the course of the disease, and differences between patient types. In this direction, the Nursing Model Based on Daily Living Activities systematizes and groups care for individuals with a holistic approach and allows the individual to diagnose how much he can do these activities on his own and independently. In this way, the individual can be allowed to go through the pre-death process in a manner worthy of human dignity. Aim: In this case report, it is aimed to diagnose, evaluate and manage the nursing process of a lung cancer patient hospitalized in a palliative care center in accordance with the "Roper, Logan, Tierney Nursing Model". Method: A 67-year-old male patient, hospitalized in a city hospital palliative care center in Turkey, is receiving treatment and rehabilitation with the diagnosis of "Pulmonary Disease". During the rehabilitation process, the patient was handled with a holistic approach and diagnosed with the contribution of the nursing model based on daily life activities, the nursing process was managed, the nursing diagnoses identified in the patient and interventions appropriate to these diagnoses were planned and implemented. The case report study was explained and verbal and written informed consent was obtained from the patient's relative. Results: After the analysis of the systematized data, the problems were revealed more clearly and solution-oriented approaches were developed. Conclusion: It has been observed that the application of the nursing model based on daily life activities in the nursing process increases the quality of care.
