Spiritual nursing education programme for nursing students in Korea: a systematic review and meta-analysis.

PURPOSE: This study conducts a systematic review and meta-analysis to understand the characteristics and contents of studies on spiritual nursing education programmes and their effects. METHODS: The literature search included five databases (RISS, KISS, DBpia, Science ON, and KmBase) published in South Korea until September 30, 2021. Nine studies were included in the final review, with six for the meta-analysis using the RevMan 5.4. 1 programme. The programmes targeted nursing students and nurses in the RN-BSN course and employed methods such as lecturing, discussions, and case presentations. The contents focused on self-spirituality awareness, spirituality-related concepts, understanding others' spirituality, and the process and application of spiritual nursing. RESULTS: The meta-analysis revealed statistically significant effects on spiritual nursing competencies, spirituality, spiritual well-being, existential well-being, and spiritual needs, except self-esteem. Spiritual nursing education was effective in enhancing spiritual nursing competencies. CONCLUSION: The study confirmed that spiritual nursing education effectively improves spiritual nursing competency, indicating a need for increased focus and administrative and financial support for such education in schools and hospitals. Furthermore, future studies should employ randomised experimental designs to examine the effects of online education programmes with short training time on clinical nurses in hospitals.

Health and medical experience of migrant workers: qualitative meta-synthesis.

BACKGROUND: Migrant workers in Korea are contributing to economic development by resolving labour shortages due to the increase in the ageing population, and they have become necessary and important in the Korean economy. However, long working hours, poor working conditions, and cultural differences can cause migrant workers to experience disadvantages in using health and medical services. Therefore, this study aimed to understand and analyse the health and medical service experience of migrant workers in Korea by reviewing previous studies in order to improve their health and access to medical services. METHOD: The qualitative meta-synthesis method suggested by Thomas and Harden was used. The key question for searching the literature is 'What is the status of the use of health and medical service by migrant workers in Korea and the attributes that affect them?' Five electronic databases (RISS, KCI, KISS, Science ON, and KMbase) were searched for Korean literature published in academic journals until 6 November 2022 using a combination of "migrant worker or foreign worker or foreign labourer or migrant" and "medical or health" in Korean. RESULTS: A total of nine studies out of 1,006 were included in the review after methodological quality assessment using the Critical Appraisal Skills Program (CASP). The results of studies were synthesised into three themes and ten sub-themes: 'Personal factors' of personal health beliefs and the financial burden of healthcare costs; 'Cultural factors' of cultural differences in the lifestyle, cultural differences in the healthcare environment, and traditional medicine in the country; and 'Socio-institutional factors' of poor and difficult working environment, insufficient information about medical institutions, policies with a lack of practical applicability, systems of healthcare institutions, and healthcare services usage. CONCLUSIONS: This study identified the experiences of migrant workers in using health and medical care services. The results of this study can be used as a basis for improving the health of migrant workers and access to healthcare services. Based on the results of this study, it is necessary to improve the health management ability of migrant workers by developing a health management platform that can support Korean medical information and provide professional and accurate self-health management information.

Health-related quality of life of migrant workers: a systematic literature review.

BACKGROUND: Currently, the number of migrant workers residing in Korea is continuously increasing, which is exacerbating the workforce shortage in its society. Migrant workers experience health problems or stress due to rapid environmental changes, consequently impairing their quality of life (QoL). Accordingly, this literature review aimed to prepare basic data by identifying factors related to the health-related quality of life (HRQoL) of migrant workers in Korea. METHOD: In total, the literature search used seven databases to find all documents corresponding to related subject words until June 7, 2022, including PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Regional Information Sharing Systems, Korean Medical database, Science ON, and DataBase Periodical Information Academic. Furthermore, this study used the Cochrane Library and Google Scholar to manually search, to include comprehensive literature. Moreover, both English and Korean were used to search for the main terms. RESULTS: In total, nine articles were selected. The World Health Organization Quality of Life Brief Version tool was used in six studies to measure HRQoL. Factors affecting the HRQoL of domestic migrant workers included general characteristics such as monthly income and residence period, physical and psychological health-related characteristics such as health promotion behaviour, medical service satisfaction, and depression, and social factors such as social support and cultural adaptation stress. Social support was an important variable affecting the QoL. Particularly, increased social support improved health-related QoL. In addition, higher medical service satisfaction and lower cultural adaptation stress increased HRQoL. CONCLUSIONS: Social factors such as social support and cultural adaptation stress affect the HRQoL of migrant workers. Therefore, the social integration program should be expanded to ensure that migrant workers can adapt to the domestic culture at an early stage. In addition, people require active support to improve the QoL in Korea through activities such as self-help groups to help them cope with stressful situations and experience positive emotions. Moreover, it is necessary to provide information on domestic medical services as well as support for medical information for self-health management to improve the quality of medical services for migrant workers.

The Effect of Role Conflict and Professional Autonomy on the Role Performance of Patient Safety Coordinators in Small and Medium-Sized Hospitals in Korea.

This study aimed to investigate the effects of role conflict and professional autonomy on the role performance of patient safety coordinators in small and medium-sized hospitals in Korea. The participants in this cross-sectional study were 121 patient safety coordinators in general hospitals or hospitals with more than 100−300 beds. Data were collected through an online survey for about three weeks in February 2022. The variables were role conflict, professional autonomy, and role performance. In the data analysis, we employed the t-test, ANOVA, correlation, and multiple regression methods. Almost all (99.2%) of the participants were nurses. The lower the role conflict and the higher the professional autonomy, the better the role performance shown. As a result of analyzing the factors affecting role performance, the regression model was found to be significant (F = 6.988, p < 0.001). The most influential factor in role performance was professional autonomy (ß = 0.279, p = 0.002). In conclusion, it is thought that systematic education and legal and institutional arrangements for independent roles and work regulations are needed to strengthen patient safety coordinators' competency in small and medium-sized hospitals in Korea. This will improve the role performance of patient safety coordinators and create a better patient safety culture.

Fast and slow proton transfer in ice: the role of the quasi-liquid layer and hydrogen-bond network.

The proton mobility in ice is studied through molecular dynamics simulations carried out with a newly developed ab initio-based reactive force field, aMS-EVB3/ice. The analysis of both structural and dynamical properties of protonated ice as a function of temperature indicates that the mobility of excess protons at the surface is largely suppressed, with protons becoming essentially immobile at temperatures below 200 K. In contrast, fast proton transfer/transport can exist in bulk ice Ih at low temperature through connected regions of the proton-disordered hydrogen-bond network. Based on the simulation results, it is shown that the mechanisms associated with proton transfer/transport in both bulk and interfacial regions of ice are largely dependent on the local hydrogen-bond structure surrounding the charge defect. A molecular-level picture of the mechanisms responsible for proton transfer/transport in ice is then developed and used to interpret the available experimental data.

Direct dynamics simulation of dioxetane formation and decomposition via the singlet ·O-O-CH2-CH2· biradical: non-RRKM dynamics.

Electronic structure calculations and direct chemical dynamics simulations are used to study the formation and decomposition of dioxetane on its ground state singlet potential energy surface. The stationary points for (1)O(2) + C(2)H(4), the singlet ·O-O-CH(2)-CH(2)· biradical, the transition state (TS) connecting this biradical with dioxetane, and the two transition states and gauche ·O-CH(2)-CH(2)-O· biradical connecting dioxetane with the formaldehyde product molecules are investigated at different levels of electronic structure theory including UB3LYP, UMP2, MRMP2, and CASSCF and a range of basis sets. The UB3LYP/6-31G∗ method was found to give representative energies for the reactive system and was used as a model for the simulations. UB3LYP∕6-31G∗ direct dynamics trajectories were initiated at the TS connecting the ·O-O-CH(2)-CH(2)· biradical and dioxetane by sampling the TS's vibrational energy levels, and rotational and reaction coordinate energies, with Boltzmann distributions at 300, 1000, and 1500 K. This corresponds to the transition state theory model for trajectories that pass the TS. The trajectories were directed randomly towards both the biradical and dioxetane. A small fraction of the trajectories directed towards the biradical recrossed the TS and formed dioxetane. The remainder formed (1)O(2) + C(2)H(4) and of these ∼ 40% went directly from the TS to (1)O(2) + C(2)H(4) without getting trapped and forming an intermediate in the ·O-O-CH(2)-CH(2)· biradical potential energy minimum, a non-statistical result. The dioxetane molecules which are formed dissociate to two formaldehyde molecules with a rate constant two orders of magnitude smaller than that predicted by Rice-Ramsperger-Kassel-Marcus theory. The reaction dynamics from dioxetane to the formaldehyde molecules do not follow the intrinsic reaction coordinate or involve trapping in the gauche ·O-CH(2)-CH(2)-O· biradical potential energy minimum. Important non-statistical dynamics are exhibited for this reactive system.

A refined MS-EVB model for proton transport in aqueous environments.

In order to improve the description of proton mobility in aqueous environments, a revised multistate empirical valence bond model (aMS-EVB3) is developed. The new aMS-EVB3 model is built upon an anharmonic water force field (aSPC/Fw) in which the OH bond potential is described through a quartic approximation to a Morse potential. First, it is shown that the aSPC/Fw anharmonic water model provides an accurate description of water at ambient conditions and reproduces the available experimental data for several structural, thermodynamic, and dynamical properties. Second, it is shown that, when applied to the study of proton solvation and transport in bulk water, the new aMS-EVB3 model accurately describes the solvation structure around the excess proton. Importantly, the new aMS-EVB3 model predicts a significantly larger proton diffusion coefficient than previous models, which largely improves the agreement with the available experimental data.

Application of Adaptive QM/MM Methods to Molecular Dynamics Simulations of Aqueous Systems.

The difference-based adaptive solvation quantum mechanics/molecular mechanics (adQM/MM) method (J. Chem. Theory Comput.2009, 5, 2212) as implemented in the Amber software was applied to the study of several chemical processes in solution. The adQM/MM method is based on an efficient selection scheme that enables quantum-mechanical treatment of the active region of a molecular system in solution taking explicitly into account diffusion of solvent molecules between the QM and the MM regions. Specifically, adQM/MM molecular dynamics simulations are carried out to characterize (1) the free energy profiles of halide exchange SN2 reactions in water, (2) the hydration structure of the Cl(-) ion, and (3) the solvation structure of the zwitterionic form of glycine in water. A comparison is made with the results obtained using standard MM and QM/MM methods as well as with the available fully QM and experimental data. In all cases, it is shown that the adaptive QM/MM simulations provide a physically realistic description of the system of interest.

Algorithms for sampling a quantum microcanonical ensemble of harmonic oscillators at potential minima and conical intersections.

Algorithms are presented for sampling quantum microcanonical ensembles for a potential energy minimum and for the conical intersection at the minimum energy crossing point of two coupled electronic states. These ensembles may be used to initialize trajectories for chemical dynamics simulations. The unimolecular dynamics of a microcanonical ensemble about a potential energy minimum may be compared with the dynamics predicted by quantum Rice-Ramsperger-Kassel-Marcus (RRKM) theory. If the dynamics is non-RRKM, it will be of particular interest to determine which states have particularly long lifetimes. Initializing a microcanonical ensemble for the electronically excited state at a conical intersection is a model for electronic nonadiabatic dynamics. The trajectory surface-hopping approach may be used to study the ensuing chemical dynamics. A strength of the model is that zero-point energy conditions are included for the initial nonadiabatic dynamics at the conical intersection.

Singlet and triplet potential surfaces for the O2+C2H4 reaction.

Electronic structure calculations at the CASSCF and UB3LYP levels of theory with the aug-cc-pVDZ basis set were used to characterize structures, vibrational frequencies, and energies for stationary points on the ground state triplet and singlet O(2)+C(2)H(4) potential energy surfaces (PESs). Spin-orbit couplings between the PESs were calculated using state averaged CASSCF wave functions. More accurate energies were obtained for the CASSCF structures with the MRMP2/aug-cc-pVDZ method. An important and necessary aspect of the calculations was the need to use different CASSCF active spaces for the different reaction paths on the investigated PESs. The CASSCF calculations focused on O(2)+C(2)H(4) addition to form the C(2)H(4)O(2) biradical on the triplet and singlet surfaces, and isomerization reaction paths ensuing from this biradical. The triplet and singlet C(2)H(4)O(2) biradicals are very similar in structure, primarily differing in their C-C-O-O dihedral angles. The MRMP2 values for the O(2)+C(2)H(4)→C(2)H(4)O(2) barrier to form the biradical are 33.8 and 6.1 kcal/mol, respectively, for the triplet and singlet surfaces. On the singlet surface, C(2)H(4)O(2) isomerizes to dioxetane and ethane-peroxide with MRMP2 barriers of 7.8 and 21.3 kcal/mol. A more exhaustive search of reaction paths was made for the singlet surface using the UB3LYP/aug-cc-pVDZ theory. The triplet and singlet surfaces cross between the structures for the O(2)+C(2)H(4) addition transition states and the biradical intermediates. Trapping in the triplet biradical intermediate, following (3)O(2)+C(2)H(4) addition, is expected to enhance triplet→singlet intersystem crossing.

O((3)P) + C(2)H(4) potential energy surface: study at the multireference level.

The O((3)P) + C(2)H(4) reaction provides a crucial, initial understanding of hydrocarbon combustion. In this work, the lowest-lying triplet potential energy surface is extensively explored at the multiconfiguration self-consistent field (MCSCF) and MRMP2 levels with a preliminary surface crossing investigation; and in cases that additional dynamical correlation is necessary, MR-AQCC stationary points are also determined. In particular, a careful determination of the active space along the intrinsic reaction pathway is necessary; and in some cases, more than one active space must be explored for computational feasibility. The resulting triplet potential energy surface geometries mostly agree with geometries from methods using single determinant references. However, although the selected multireference methods lead to energetics that agree well, only qualitative agreement was found with the energetics from the single determinant reference methods. Challenges and areas of further exploration are discussed.

Importance of shattering fragmentation in the surface-induced dissociation of protonated octaglycine.

A QM + MM direct chemical dynamics simulation was performed to study collisions of protonated octaglycine, gly(8)-H(+), with the diamond {111} surface at an initial collision energy E(i) of 100 eV and incident angle theta(i) of 0 degrees and 45 degrees. The semiempirical model AM1 was used for the gly(8)-H(+) intramolecular potential, so that its fragmentation could be studied. Shattering dominates gly(8)-H(+) fragmentation at theta(i) = 0 degrees, with 78% of the ions dissociating in this way. At theta(i) = 45 degrees shattering is much less important. For theta(i) = 0 degrees there are 304 different pathways, many related by their backbone cleavage patterns. For the theta(i) = 0 degrees fragmentations, 59% resulted from both a-x and b-y cleavages, while for theta(i) = 45 degrees 70% of the fragmentations occurred with only a-x cleavage. For theta(i) = 0 degrees, the average percentage energy transfers to the internal degrees of freedom of the ion and the surface, and the energy remaining in ion translation are 45%, 26%, and 29%. For 45 degrees these percentages are 26%, 12%, and 62%. The percentage energy-transfer to DeltaE(int) for theta(i) = 0 degrees is larger than that reported in previous experiments for collisions of des-Arg(1)-bradykinin with a diamond surface at the same theta(i). This difference is discussed in terms of differences between the model diamond surface used in the simulations and the diamond surface prepared for the experiments.

Use of a single trajectory to study product energy partitioning in unimolecular dissociation: mass effects for halogenated alkanes.

A single trajectory (ST) direct dynamics approach is compared with quasiclassical trajectory (QCT) direct dynamics calculations for determining product energy partitioning in unimolecular dissociation. Three comparisons are made by simulating C(2)H(5)F-->HF + C(2)H(4) product energy partitioning for the MP26-31G(*) and MP26-311 + + G(**) potential energy surfaces (PESs) and using the MP26-31G(*) PES for C(2)H(5)F dissociation as a model to simulate CHCl(2)CCl(3)-->HCl + C(2)Cl(4) dissociation and its product energy partitioning. The trajectories are initiated at the transition state with fixed energy in reaction-coordinate translation E(t) (double dagger). The QCT simulations have zero-point energy (ZPE) in the vibrational modes orthogonal to the reaction coordinate, while there is no ZPE for the STs. A semiquantitative agreement is obtained between the ST and QCT average percent product energy partitionings. The ST approach is used to study mass effects for product energy partitioning in HX(X = F or Cl) elimination from halogenated alkanes by using the MP26-31G(*) PES for C(2)H(5)F dissociation and varying the masses of the C, H, and F atoms. There is, at most, only a small mass effect for partitioning of energy to HX vibration and rotation. In contrast, there are substantial mass effects for partitioning to relative translation and the polyatomic product's vibration and rotation. If the center of mass of the polyatomic product is located away from the C atom from which HX recoils, the polyatomic has substantial rotation energy. Polyatomic products, with heavy atoms such as Cl atoms replacing the H atoms, receive substantial vibration energy that is primarily transferred to the wag-bend motions. For E(t) (double dagger) of 1.0 kcalmol, the ST calculations give average percent partitionings to relative translation, polyatomic vibration, polyatomic rotation, HX vibration, and HX rotation of 74.9%, 6.8%, 1.5%, 14.4%, and 2.4% for C(2)H(5)F dissociation and 39.7%, 38.1%, 0.2%, 16.1%, and 5.9% for a model of CHCl(2)CCl(3) dissociation.
