Nursing process based on Betty Neuman's systemic model: A case study

This study aims to apply Betty Neuman's systemic model in the execution of the nursing process for a patient undergoing Whipple surgery. In this case study, a patient was assessed utilizing Neuman's model, wherein intrapersonal stressors encompassing physiological, psychological, socio-cultural, and spiritual dimensions, alongside interpersonal and extra personal stress factors, were systematically observed. Subsequent to the examination, three nursing diagnoses are delineated, adhering to the categorization stipulated by the International Association of Nursing Diagnosis of North America. Nursing care strategies are formulated based on three levels of prevention (primary, secondary, tertiary), as deemed significant within the framework of Neuman's perspective. The outcomes derived from this assessment informed the classification of nursing interventions and contributed to the categorization and evaluation of nursing outcomes. Consequently, it is advisable to consider the application of Neuman's model, along with other pertinent models, in the context of nursing care for the optimal well-being of patients/clients.

Effect of Betty Neuman's systemic model on the anxiety of patients undergoing endoscopy: A randomized control trial

The present study aims to determine the effect of Betty Neuman's systemic model on the anxiety of patients undergoing endoscopy. This randomized control trial investigation involved 44 participants recruited from the endoscopy center of Golestan Province Hospital in the 2022, specifically those prescribed for endoscopic procedures. The data collection instruments employed in this research encompassed a demographic characteristics questionnaire focusing on age, gender, education, and occupation, as well as Spielberger's state-trait anxiety questionnaire (form Y) (STAI-Y). The pre-intervention anxiety levels were 111.41 (SD=17.61) in the intervention group and 109.27 (SD=6.64) in the control group. The Mann-Whitney U test indicated no statistically significant difference in the anxiety levels between the two groups before the intervention (P=0.29). Following the intervention, the anxiety levels were 116.56 (SD=12.25) in the intervention group and 111.95 (SD=4.70) in the control group. The independent t-test revealed a significant difference between the two groups (P<0.01). Furthermore, the Wilcoxon test demonstrated no significant difference in anxiety levels within the control group before and after the intervention (P=0.36), whereas a significant difference was observed in the intervention group before and after the intervention (P<0.01). Moreover, the ANCOVA revealed a statistically significant difference between the two groups after accounting for the pre-test effects (Eta=0.58, P<0.01). This indicates that 58% of the variance in post-test changes can be attributed to the training provided based on the Betty Neuman's systemic model. In conclusion, the implementation of Betty Neuman's systemic model has proven to be effective in reducing anxiety levels among patients undergoing endoscopy. The demonstrated efficacy of Betty Neuman's model suggests that nursing models can serve as a cost-efficient, impactful, and secure treatment approach in patient care.

Drawdown‐induced consolidation of aquifer systems considering water‐table decline

AbstractBoundary condition is an important factor in estimating land subsidence induced by groundwater withdrawal. In previous analytical studies, the upper boundaries are commonly assumed to be constant‐head, which could fail to reflect the declines in groundwater table during groundwater pumping. A one‐dimensional (1‐D) consolidation model of aquifer systems due to groundwater drawdown is considered in this study, in which the water‐table decline is taken into account. A mathematical model, which incorporates Neuman's model of unconfined flow into Terzaghi's theory of consolidation, is first presented. The analytical solutions for both hydraulic head drawdown and subsidence are developed in the Laplace domain. A more explicit solution to the elastic, single‐layered model is also derived. The validation of the presented solutions is verified by comparing with existing solutions in degenerated cases. The results show that the presented hydraulic drawdown solutions can be used to describe the water table decline. Moreover, the subsidence solutions are notably different from solutions based on the commonly‐used constant‐head boundary, and these previous models could severely underestimate the subsidence. The influences of specific yield, compressibility of the pore water, hydraulic conductivity, and viscosity of soil skeleton on the water table decline and long‐term deformation are also investigated using the presented solutions.

The Evaluation of the Hydrogeological Parameters of a Field Pumping Test within Multi-layer Unconfined Pebble Aquifers: A Case Study

This paper presents a case study of field pumping tests and the evaluation of the hydrogeological parameters of the unconfined pebble aquifers in the test site located at Shijiawan station in Luoyang City, China, which guarantees the construction safety of Metro Line 1. Multiple groups of single-well pumping tests and one group-well pumping test were conducted to obtain the aquifers’ hydrogeological parameters. Then, a combination of theoretical analysis and numerical simulation was used to evaluate the aquifers’ hydrogeological parameters. The analytical solutions were obtained for the unconfined, anisotropic pebble aquifers using the Neuman model. The numerical simulation was established via the finite element method (FEM). The calculation results indicate that the theoretical analysis and numerical simulation parameters are well matched. Moreover, the results of the numerical method which considers the heterogeneous and horizontal isotropic characteristics of the pebble stratum, as well as the hydrogeological parameters are more reliable than the results obtained by the theoretical analysis. The pumping tests also indicate that the supporting structure plays a significant role in waterproofing during dewatering construction.

Biomolecular Quantum Computation

In terms of leveraging the total power of quantum computing, the prevalent current (2020) model of designing quantum computation devices to follow the von Neuman model of abstraction is highly unlikely to be making full use of the full range of computational assistance possible at the atomic and molecular level. This is particularly the case for molecular modeling, in using computational models that more directly leverage the quantum effects of one set of molecules to estimate the behavior of some other set of molecules would remove the bottleneck of insisting that modeling first be converted to the virtual binary or digital format of quantum von Neuman machines. It is argued that even though this possibility of “fighting molecular quantum dynamics with molecular quantum dynamics” was recognized by early quantum computing founders such as Yuri Manin and Richard Feynman, the idea was quickly overlooked in favor of the more computer-compatible model that later developed into qubits and qubit processing.

Comparing pumping test between Boulton and Neuman in unconfined aquifer

Groundwater is known as a crucial source of water in the history of human, as it less contaminated, it has more preferable than surface water. Analyzing data of pumping test for evaluating aquifer parameters specific yield (Sy), transmissivity (T) and storativity (S) are usually using standard procedures like Theis or Jacob method. Boulton was the first to present the delayed response concept of unconfined aquifers under pumping conditions. Then Neuman used a different method than Boulton to develop an analytical model for a fully penetrating well in unconfined aquifers. The Neuman's model is depended on physical parameters which are well defined in aquifer system that is the main difference comparing to Boulton model. The main objective of this research on understanding water table aquifers in the Xabat area is to analyze the two main Boulton and Neuman methods by using aquifer test pro 2016 software and to see which of them are most appropriate for this area, which is the main reason for applying and comparing the two methods. The results of the layer property (specific yield, transmissivity, and storativity) are similar depending on the user and the availability of the methods, as well as the future development of the program analysis.

Modifying Stressors Using Betty Neuman System Modeling in Coronary Artery Bypass Graft: a Randomized Clinical Trial.

Introduction: Coronary artery disease (CAD) is one of the major causes of mortality all over the world. In this relation, coronary artery bypass grafting (CABG) is one of the most important treatments for CAD patients. However, it leads to a lot of stress in the patient. The aim of this study was to use the Neuman model to moderate the stressors in patients undergoing coronary artery bypass graft.Methods: This study was a randomized clinical trial of two groups performed on patients admitted to the coronary artery bypass graft; and the study completed with 64 patients. The intervention was performed by the researcher according to the format of the Neuman Model, which included the investigation of the stressors, and the determination of the goals and strategies for the actions. Intrapersonal, interpersonal, and extra personal factors were evaluated using a Revised Cardiac Surgery Stressor Scale (RCSSS). The intervention program was designed by the researcher based on prevention levels using scientific resources. The collected data were analyzed in SPSS ver. 13 using descriptive and inferential statistics.Results: Before the intervention, the mean score of the stressors was not significantly different between the two groups. But immediately after the intervention and before discharging the intervention group, it was significantly less than the control group.Conclusion: Using a Neuman-based program as an effective and low-cost intervention can moderate the stressors and reduce the stress of patients awaiting coronary artery bypass graft. This theory can be a good guide to offering the roles needed to provide health services in the community.

RELASI SOSIAL DALAM PRAKTIK KEBIJAKAN CSR

This research moved from the limited study of CSR ( Corporate Social Responsibility ) to beneficiary communities in Indonesia. The theory adapted in this study is the theory of social capital by Woolcock & Narayan. The research method in this study was qualitative with the interpretive descriptive approach of the Neuman model. This study examines forms of social capital in various forms of social relations. The results of this study indicate that there are various forms of social relations that exist in society, namely bonding, bridging and linking .relations Bonding show that intra-group bonds are important to consider in order to maintain group cohesiveness.relations Bridging show that ties between groups need to be built in order to establish cooperation between the target groups and other target groups. Whereasrelations linking indicate that there is a good impact for groups that have a closer relationship with higher power institutions. These results indicate that the three forms of social relations have an impact on the implementation of CSR in a company. This relationship is important to be maintained through communication activities aimed at development carried out through more intensive, open and participatory ways to create healthy and sustainable social relations.

Nursing Diagnoses in Institutionalized Elderly Individuals according to Betty Neuman

Objective: To identify nursing diagnoses in caregivers of institutionalized elderly and to associate them with stressors, according to the Betty Neuman Model. Materials and Methods: A cross-sectional, descriptive and quantitative study with 41 formal caregivers of institutionalized elderly. The data were collected using a structured form according to the Betty Neuman Systems Model. Subsequently, the diagnoses were formulated based on the NANDA-I Taxonomy and these were associated with the stressors perceived by the caregiver. Results: There was a prevalence of women with eight to 12 years of schooling who did not attend a caregiver course for the elderly. The stressors perceived by caregivers were family, financial, work and health. Fifteen nursing diagnoses were identified, highlighting: Sedentary lifestyle, anxiety, stress overload and impaired comfort. Conclusions: The use of the Neuman Model facilitated the identification of nursing diagnoses. The family stressor was the most prevalent in the caregivers’ report. The main diagnoses identified show the need to meet the health demands of caregivers, since they can impact on the quality of care provided to the elderly.

Water table response to a pumping test in the hinterland core area of the Taklimakan Desert, China

Wei, Y., Fan, J., Xu, X., & Lei, J. (March-April, 2017). Water table response to a pumping test in the hinterland core area of the Taklimakan Desert, China. Water Technology and Sciences (in Spanish), 8(2), 151-158. In this article, hydrogeological parameters were determined by a single well pumping test. Over the course of the study, BETCO was used to eliminate the effects of atmospheric pressure changes on water level based on the regression deconvolution method. The aquifer test was used to analyze data and to calculate hydrogeological parameters. Finally, from the three unconfined aquifer models, though the Boulton model cannot successfully gain well-fitting results, the Theis model with Jacob correction and the Neuman model results obtained hydrogeological parameters by curve-fitting. Additionally, permeability coefficient of the two models is in good agreement with previous research, which can provide a reference for further study in the hinterland of the desert, especially for the construction of hydrological modeling research.

A Beginner’s Guide to Writing the Nursing Conceptual Model-Based Theoretical Rationale

Writing the theoretical rationale for a study can be a daunting prospect for novice researchers. Nursing's conceptual models provide excellent frameworks for placement of study variables, but moving from the very abstract concepts of the nursing model to the less abstract concepts of the study variables is difficult. Similar to the five-paragraph essay used by writing teachers to assist beginning writers to construct a logical thesis, the authors of this column present guidelines that beginners can follow to construct their theoretical rationale. This guide can be used with any nursing conceptual model but Neuman's model was chosen here as the exemplar.

Holistic Interventions Protocol for Interstitial Cystitis Symptom Control

Interstitial cystitis (IC) is a disabling bladder disorder that leads patients on an endless journey in search of treatment options to control their painful symptoms. Although there are some medical treatments available, no one treatment is completely effective. The Neuman model provides the rationale for the use of holistic prevention interventions with IC patients. Holistic interventions can help IC patients to retain, attain, and maintain system stability. A case study of 1 IC patient, who successfully used holistic approaches to achieve system stability, is described.

Aquifer parameter identification using the extended Kalman filter

An approach using the extended Kalman filter (EKF) and cubic spline is proposed to identify the aquifer parameters in both confined and unconfined aquifer systems. The cubic spline applied to the observation data can generate interpolated data with uniform time intervals and facilitates the implementation of EKF. The EKF combined with the Theis solution or Neuman's model, using the interpolated drawdown data produced by cubic spline, can optimally determine the parameters through the recursive process. The proposed approach can quickly identify the parameters, using only part of observed drawdown data, and the obtained parameters are shown to have good accuracy. Thus length of time of pumping tests may be shortened. Comparisons of results from nonlinear least squares combined with finite difference Newton's method (NLN) and EKF show that the EKF allows a wider range of initial guess values than NLN and have the accuracy of the results on the same order of magnitude as that of NLN. When determining the aquifer parameters, the identification process of specific yield reflects the effect of gravity drainage on the drawdown curve and conforms to the physical nature of an unconfined aquifer. Furthermore, this study shows that EKF can be successfully applied to analyze the drawdown data even with white noises or temporally correlated noises.

Grief Is More Than Tears

Much has been written in the professional and popular literature about grief. The multiplicity of sources for information about the phenomenon often leads to confusion regarding terminology and process. In addition, assessment and intervention methods show the phenomenon as unidimensional despite evidence to the contrary. Because nursing routinely deals with grief, it is important that a framework be developed to help understand the process and guide appropriate interventions. The Neuman systems model is particularly well suited as a framework because concepts found in the model are similar to descriptions of the concept of grief. An analysis of the grief concept using the Neuman model is presented, with perinatal grief presented as an example.

Quality of life and chronic nonmalignant pain

Chronic nonmalignant pain is a prevalent and costly phenomenon. Chronic pain induces stressors that affect personal and work lives of sufferers. Because of this interference, quality of life is impacted. The purpose of this pilot study was to explore the impact of stressors on the quality of life of adult patients with chronic pain. The framework guiding this study was Neuman's Systems Model based on the concepts of stress and reaction to stress. A descriptive correlational research design was used to compare participants' quality of life according to their health and function; family, psychological, spiritual, and socioeconomic status; and the stressors of age, gender, income, marital and work status, occupation, monthly treatment costs, and type of insurance. Each participant was administered the Ferrans and Powers Quality-of-Life Index and a demographic survey. Results revealed that a higher quality of life was associated with participants who were older, female, and employed, whereas a lower quality of life was associated with participants with a low income, higher treatment costs, and a lack of workmen's compensation insurance. Based on Neuman's model, the implications of chronic pain sufferers' resistance to the negative impact of various stressors are discussed. © 2001 by the American Society of Pain Management Nurses

A community needs assessment for a SANE program using Neuman's model.

To present guidelines for a community needs assessment for a Sexual Assault Nurse Examiner (SANE) program using Neuman's Systems Model. The guidelines provide advanced practice nurses with a holistic, systematic means to conduct an assessment prior to the implementation of a SANE program and facilitate collaborative work with other disciplines and agencies. Selected research-based articles on sexual assault, classic texts and writings on Neuman's Systems Model, and community assessment models and programs. Sexual assault is a problem faced by almost every community. A thorough community assessment is an important first step in establishing programs that adequately meet a community's needs. Guidelines for conducting such an assessment related to implementation of a SANE program are rare, and guidelines using a nursing model were not found in the literature. One program that has been successful in meeting community needs is the SANE program. A concise and organized assessment guide can reduce the necessary time and money allocated for a community assessment and can provide a basis for evaluation and research.

An exploration of family-centred care in Neuman's model with regard to the care of the critically ill adult in an accident and emergency setting

In Accident and Emergency (A & E) departments there is a tendency to separate relatives from critically ill patients, and although in many departments the relatives have a nurse allocated to care for them, this care is often given in a separate ‘relatives’ room. This article explores the meanings of family, family nursing and family systems nursing in the context of an A & E setting and using Neuman's (1989) model to highlight family dynamics. The intention is to allow the thinking A & E nurse to reflect on care given in the department, so that individualised care can be given with consideration to the relationships that the person has before they take on the status of ‘patient’. Thus, the article is meant to be thought-provoking rather than prescriptive.
