Published: May 2024

Relevance. Correct planning and improving the effectiveness of field geophysical surveys in horizontal wells with multi-stage hydraulic fracturing. Wide distribution of horizontal wells with multi-stage hydraulic fracturing requires development of methods of researching hydraulic fractures in the field of optimization of completion technologies, hydraulic fracturing and field development monitoring. The instrumental methods of researching fluid inflow, which include field geophysical research, under conditions of horizontal wells with multistage fracturing, find out the set of missing, which essentially reduce it reliability. Aim. Improvement of the quality of field logging in horizontal wells with multistage fracturing by developing criteria for application of research technologies. Methods. Analysis of field geophysical data of horizontal wells with hydraulic fractures in PJSC Rosneft Oil Company. Results. The authors have developed an expert decision-making system, which has the form of matrix with criteria of application of field geophysical research methods to horizontal wells with multistage hydraulic fracturing. This matrix enables in dependence on the well parameters (well construction, number and position of hydraulic fracturing ports, well fluid content) and scenario conditions (type of problem to be solved, inflow localization, characteristics of geophysical devices) to estimate the probability of delivery of devices inside the well with different ways, the informative value of field geophysical research, the quality of solution of the problem to be set. During pilot works the matrix was improved by the methods of researching low-rate horizontal wells. The paper also considered the experience of using low-rate wells with a packer flow meter and spectral noise logging.

Relevance. Tense ecological situation in the impact zone of the large industrial complex of Usolye-Sibirskoe on the Angara river, search for sources and ways of pollutants inflow during different periods of technogenic load, necessary to assess and forecast the current changes in the aquatic ecosystem. Aim. To study chemical composition of wastewater from the industrial zone of Usolye-Sibirskoe during different periods of technogenic load and assess their impact on hydrochemical parameters of the Angara river water. Objects. Wastewater from the industrial zone of Usolye-Sibirskoe and Angara river waters in the impact area during the period of high technogenic load (2010) and the period of its reduction (2020). Methods. Chemical composition of wastewater and natural water was determined in the Center of Collective Use «Isotope-Geochemical Investigations» of Vinogradov Institute of Geochemistry SB RAS (Irkutsk, Russia). Concentrations of major ions in waters were measured using a set of methods generally accepted in hydrochemistry (atomic absorption and atomic emission flame spectrometry, spectrophotometry, potentiometry, titrimetry), Hg concentration was measured using atomic absorption spectrometry, concentrations of other trace elements – using mass spectrometry method (ISP MS). Results. The authors have revealed significant changes in chemical composition of wastewater of the industrial zone in different periods of technogenic load, reflecting the transformation of pollution sources during the liquidation of technogenic objects of the area. Over the ten-year period particularly important changes are expressed in a significant decrease of Hg, Al, Cs, Ti, Cr, Cl– and Na+ concentrations and increase of Mn concentrations in the wastewater of the industrial zone. This is reflected, in its turn, in the dynamics of hydrochemical composition of Angara river water in the impact area. In 2010 a regular consecutive decrease of most of elements concentrations was observed with distance of Angara river waters from technogenic sources. Where as in 2020 their spatial distribution is opposite: with a significant decrease in concentrations of most of the studied elements at the river site 50 m downstream of industrial discharges, their increase was detected at more distant monitoring stations (1.5 and 5 km) where Mn, Cu, Cd and Tl concentrations were the highest. Despite significant changes in wastewater chemical composition in different periods of technogenic load, the Angara river waters at all monitoring stations in the impact zone of the industrial complex of Usolye-Sibirskoe are polluted.
Tellurum-bismuth mineralization in ores of the Maleevskoe pyrite deposit (Eastern Kazakhstan)
Authors: Nikolaeva Anastasia N. , Mazurov Alexey K.
Published: May 2024

As it is known, Rudny Altai is a classic province of sulfide deposits, most of which were formed in paleo-island-arc geodynamic settings. Pyrite ores have a complex and diverse chemical composition, including a wide range of impurity elements, among which the metalloid tellurium and the metal bismuth still remain poorly studied. Based on the above, we investigated tellurium-bismuth mineralization in the sulfide ores of the Maleevskoe deposit, confined to the Zyryanovsky cluster of Rudny Altai. Relevance of research is caused by the lack of information about the nature of the distribution and forms of occurrence of this type of rare minerals in the ores of pyrite deposits of Rudny Altai. The data obtained from this study will allow for more comprehensive processing and use of mineral resources. Aim of the study is to characterize the material composition of ores; identify the features of the development of tellurium-bismuth mineralization and determine the conditions for its formation; assess the prospects for associated mining and extraction of tellurium with bismuth from the ores of sulfide deposits of Rudny Altai. Object. Tellurium-bismuth mineralization of sulfide ores of the deposit. Methods. Petrographic, mineragraphic and mineralogical analyses, scanning electron microscopy in combination with X-ray microanalysis and Raman spectroscopy. Results. The ores revealed a variety of tellurium-bismuth mineralization, which is recorded as independent minerals, represented by sulfosalts, tellurides, oxides, and native forms of isolation. For the first time, such minerals as plumbotellurite PbTeO3, cervelleite Ag4TeS, xilingoite Pb3Bi2S6 and an unidentified mineral with the general formula PbAg2Te were discovered for these ores. Minerals of tellurium-bismuth composition in relation to the main ore minerals are characterized by later crystallization into the Ag-Te-Bi-sulfide association of the ore stage at a temperature of 280...150°С. Based on the data obtained, the authors predicted the prospects for tellurium and bismuth extraction from ores of deposits similar in material composition to the Maleevskoe deposit and confined to the ore cluster of the same name.

Authors: O’Neil Amanda , Schumacher Bette , Dorr Sarah , Jarding Laura
Published: May 2024

In a sixty-eight-bed level-IV NICU, an increased incidence of hospital-acquired pressure injuries (HAPIs) from noninvasive ventilation (NIV) devices was identified. The aim of this quality improvement project was to decrease HAPIs from NIV by 10%. A literature review and the Plan–Do–Study–Act were implemented. The intervention included a customized silicone foam dressing under NIV, an NIV skincare bundle, and multidisciplinary support. Hospital-acquired pressure injury rates were tracked over 3 years postinterventions. The incidence of HAPIs declined by 20% from 0.2 per 1,000 patient days to 0.05 per 1,000 patient days. Relative risk was 4.6 times greater prior to intervention (p= .04). Continuous positive airway pressure (CPAP) failure was not noted and measured by the percentage of patients on ventilators pre- and postintervention. Customized silicone foam dressings under NIV, NIV skincare bundle, and multidisciplinary team support may decrease HAPIs in neonates without CPAP failure.

Graph theory is one of the subjects in Discrete Mathematics that have long been known and are widely applied in various fields. The topics that are often discussed in graph theory include labeling, coloring, chromatic numbers, metric dimensions, and partition dimensions. Partition dimensions are obtained by grouping all the vertices on the graph into a number of partition classes, then determine the distance of all vertices to each partition class to get a representation. Partition class which representations have different coordinate vectors is called resolving partition. The minimum cardinality of resolving partition is called partition dimensions of the graph. The purpose of this study is to determine the partition dimensions of level corona operation graphs which are GʘkPm, GʘkCm and GʘkKm, where G, Pm, Cm and Km are connected non trivial graph, path graph, circle graph and complete graph respectively, and any integer k≥1.

Preeclampsia is the biggest cause of morbidity and mortality worldwide and the second most common cause of maternal death in Indonesia. One of the highest risk factors for preeclampsia is anemia, so this study aimed to conduct a systematic review of the relationship between anemia in pregnant women and the incidence of preeclampsia. This research was an analytic type with a systematic review method from previous research with an observational case-control approach design with secondary data sources. The data were obtained from the results of previous research with a literature time limit of the last 5 years (2018–2022). This study used databases from Google Scholar, Pubmed, ScienceDirect, Garuda, and Summon Universitas Airlangga. The search yielded 2161 studies; after eliminating 439 duplicates, 1732 remained. After exclusion based on titles and abstracts, 36 studies remained, which were screened in full text. Finally, 8 studies were eligible and included in the review. Four studies showed a relationship between anemia in pregnant women and the incidence of preeclampsia, while four other studies showed no relationship. The prevalence of anemia in pregnant women in Indonesia ranges from 13.27% to 80.8%, with an average of 44.1%. Ages at risk for preeclampsia in Indonesia are pregnant women aged <20 years and >35 years. There is a relationship between anemia in pregnant women and the incidence of preeclampsia in Indonesia. Therefore, anemia can be a risk factor for preeclampsia.
Dynamic Style Analysis and Performance Evaluation of Global Bond Funds
Authors: Polwitoon Sirapat , Tawatnuntachai Oranee
Published: May 2024

Using a sample of 103 surviving and non-surviving global bond funds over a long sample period of 1998 to 2022, we perform a comprehensive analysis of the funds under our modified Sharpe’s (1992) style analysis model. We find that dynamic style analysis is useful in explaining time-series and cross-sectional and in predicting future returns of global bond funds. The dynamic style analysis also allows us to examine asset allocation over time. The results show that, during 2001 to 2014, funds shift their allocations from intermediate-term bonds to world corporate bonds and from world corporate bonds to emerging market bonds in search of higher returns at the price of credit quality.
Gradient Based Aero-Stealth Optimization of a Simplified Aircraft
Authors: Thoulon Charles , Roge Gilbert , Pironneau Olivier
Published: May 2024

Modern fighter aircraft increasingly need to conjugate aerodynamic performance and low observability. In this paper we showcase a methodology for a gradient-based bidisciplinary aero-stealth optimization. The shape of the aircraft is parametrized with the help of a CAD modeler, and we optimize with the SLSQP algorithm. The drag, computed with the help of a RANS method, is used as the aerodynamic criterion. The stealth criterion, a function is derived from the radar cross section in a given cone of directions, weighed with a function whose goal is to cancel the electromagnetic intensity in a given direction. Stealth is achieved passively by scattering back the electromagnetic energy away from the radar antenna and no energy is absorbed by the aircraft, which is considered as a perfect conductor. A Pareto front is identified by varying the weights of the aerodynamic and stealth criteria. The Pareto front allows for an easy identification of the CAD model corresponding to a chosen aero-stealth trade-off.

Mutualism between insects and symbiotic bacteria drives insect evolution, and insecticide resistance is affected by symbiotic bacteria, increasing the complexity of pest resistance. This study evaluated the sublethal and transgenerational effects of the neonicotinoid insecticide nitenpyram on the population dynamics of Acyrthosiphon gossypii and measured its impact on the symbiotic bacterial community. The results showed that LC20 (2.49 mg·L−1) of nitenpyram significantly reduced the fecundity and lifespan of the parent G0 generation of A. gossypii, and had similar inhibitory effects on its G1 and G2 generations. Compared with those of control group, the population parameters λ (finite rate of increase), R0 (net reproductive rate), and r (intrinsic increase rate) of G1 and G2 were significantly reduced, but mean generation time (T) was increased. Nitenpyram treatment affected the biological traits of A. gossypii, and also changed the relative abundance of Buchnera and Sphingomonas in three consecutive generations G0-G2. Under nitenpyram treatment, the relative abundance of Buchnera decreased in G0, while that of Sphingomonas increased. The relative abundance of Buchnera increased in G1 and G2, but that of Sphingomonas decreased. Our findings may provide a new perspective for evaluating the potential effects of pesticides on aphids.

Copper (Cu) is a critical element for cancer cell proliferation and considerably accumulates in the nucleus. 64Cu2+ is an anticancer radiopharmaceuticals targeting the copper requirement of cancer cells. However, intravenously injected 64Cu2+ ions primarily accumulate in the liver. Ligand complexation of 64Cu2+ would be a promising method for increasing tumor delivery by reducing liver uptake. Herein, we used three tripodal amine ligands [tris(2-aminoethyl)amine (Tren), diethylenetriamine (Dien), and tris(2-pyridylmethyl)amine (TPMA)] to enclose 64Cu2+ ions and compared their in vivo tumor and liver uptake using a tumor-bearing xenograft mouse model of the extrahepatic bile duct carcinoma cell line TFK-1. We examined intracellular Cu distribution using microparticle-induced X-ray emission (micro-PIXE) analysis for these compounds. 64Cu2+-Tren and 64Cu2+-Dien showed higher tumor uptake than 64Cu2+-TPMA and 64Cu2+ ions in TFK-1 tumors. Among the three 64Cu2+ complexes and 64Cu2+ ions, liver uptake was inversely correlated with tumor uptake. Micro-PIXE analysis showed that in vitro cellular uptake was similar to in vivo tumor uptake and nuclear delivery was the highest for 64Cu2+-Tren. Conclusively, an inverse correlation between tumor and liver uptake was observed using three 64Cu2+ complexes of tripodal amine ligands and 64Cu2+ ions. These results provide useful information for the future development of anticancer 64Cu radiopharmaceuticals.
Enhancing Stability Criteria for Linear Systems with Interval Time-Varying Delays via Augmented Lyapunov-Krasovskii functional
Authors: Lee Dong-Hoon , Kim Yeong-Jae , Lee Seung-Hoon , Kwon Oh-Min
Published: May 2024

This work investigates the stability conditions for linear systems with time-varying delays via augmented Lyapunov-Krasovskii functional(LKF). Two types of augmented LKFs with cross terms in integral are suggested to improve the stability conditions for interval time-varying linear systems. Through this work, the compositions of the LKFs are considered to enhance the feasible region of stability criterion for linear systems. Mathematical tools such as Wirtinger-based integral inequality(WBII), zero equalities, reciprocally convex approach, and Finsler’s lemma are utilized to solve the problem of stability criteria. Two sufficient conditions are derived to guarantee the asymptotic stability of the systems using linear matrix inequality(LMI). First, asymptotic stability criteria are induced by constructing the new augmented LKFs in Theorem 1. And then simplified LKFs in Corollary 1 are proposed to show the effectiveness of Theorem 1. Second, asymmetric LKFs are shown to reduce the conservatism and the number of decision variables in Theorem 2. Finally, the advantages of the proposed criteria are verified by comparing maximum delay bounds in two examples. Two numerical examples show that the proposed Theorem 1 and 2 obtained less conservative results than existing outcomes. Also, Example 2 shows that the asymmetric LKF methods of Theorem 2 can provide larger delay bounds and fewer decision variables than Theorem 1’s in some specific systems.

Published: May 2024

Teacher self-efficacy (TSE) significantly influences teacher well-being and pedagogical quality, thereby impacting student learning outcomes. Despite the recognized effectiveness of Lesson Study (LS) in shaping teachers' practices and beliefs, there is a research gap in TSE, particularly in higher education. To address this, we conducted a longitudinal study at a northeastern Chinese university, tracking TSE evolution in three English as a Foreign Language (EFL) teachers, encompassing both novices and experienced educators, during a six-month LS program. We collected both quantitative and qualitative data, encompassing interviews, surveys, and observations. Underpinned by Bandura and Wyatt's self-efficacy theory, the impact of LS on teachers' TSE development was explored and interpreted. Our findings shed light on the many ways in which LS effects individual teachers' TSE. Notably, both novice and experienced teachers improved significantly in TSE, especially in the domains of instructional techniques and student engagement. However, in the context of classroom management, there was considerably less growth. Furthermore, our research identifies a number of challenges that can have a negative impact on teachers' TSE, such as adapting to students' changing needs, dealing with limited resources, managing time constraints, navigating the school examination system, and overcoming initial resistance to the LS approach.
Influence of helicity and alpha effect on compressible hydromagnetic turbulence of astrophysical discs with strong magnetic field
Authors: Kolesnichenko Aleksandr Vladimirovich
Published: May 2024

The influence of compressibility and rotation on turbulent transport in spiral hydromagnetic flows in the presence of an averaged velocity field and a global magnetic field is investigated using a phenomenological approach. The fluctuating effects, which are included in the averaged MHD equations through their correlation contributions and represent the Reynolds stress, turbulent electromotive force, and a number of other correlation functions, are modelled (at absence of reflection symmetry of small-scale plasma motions) using evolutionary equations and four spiral statistical characteristics of turbulence, which are: total turbulent plasma energy, dissipation rate, turbulent transverse helicity, turbulent residual energy and turbulent residual helicity. Four evolution equations for these bulk helicity quantities combined with the MHD mean-field equations leads, in particular, to a self-consistent dynamo model. The work is aimed at modelling the influence of compressibility effects on dynamical processes in hydromagnetic spiral turbulence of geo- and astrophysical objects of different nature..

Do Investments Have an Impact on Reducing Poverty? ARDL Approach
Authors: Uğurlu Süleyman
Published: May 2024

Purpose: The purpose of this research is to examine the impact of foreign direct investments (FDI) and gross fixed capital formations (GFC) on poverty reduction in Türkiye.
Design/Methodology: In this study, which analyzes the impact of investments on poverty, two different models were established. The models constructed using 1982-2020 annual data were analyzed with the ARDL method.
Findings: As a result of the analysis, both foreign direct investments and gross fixed capital formations have positive (poverty reducing) effects on poverty reduction in Türkiye. Gross fixed capital formations are more effective in reducing poverty than foreign direct investments.
Limitations: The number of poor people in Türkiye is accessed discretely. This situation has led to a limited number of empirical studies in the field of economics in Türkiye that use time series analyses related to poverty. In this study, this constraint is overcome by using household final consumption expenditures per capita (HFC) as a proxy variable as in the literature.
Originality/Value: In this study, two separate models were established with foreign direct investments and gross fixed capital formations as independent variables. The comparison of the impact of these two types of investment variables on poverty in Türkiye reveals the originality of this study.

Published: May 2024

Cultivating vannamei shrimp has dominated fishery sectors and led to aquaculture development to enhance the Indonesian economy. Lumajang, specifically Bades Village, is one of the potential regions in Jawa Timur for improving fishery products because of its long shoreline of approximately 75km. Developing shrimp cultivation requires vast funds, intensive pond systems, and broad markets. Consequently, a large number of vannamei shrimp cultivation is controlled by a large company, which will supersede the role of traditional or local fishermen. This program utilizes two main methods: socializing about the opportunity of production, cultivation, and building a business entity of vannamei shrimp and practicing creating a small pond using geomembrane as a natural insulator. These activities intend to significantly increase the interest and enthusiasm of fishermen to develop vannamei small pond systems as a solution for economic independence and new income sources. As a result, a local fishing group, widely known as Mina Dampar as a partner, accepted and approved those programs implemented in their region in a 2000m2 land area.
Muscle Strength Asymmetries of the Lower Limbs and Trunk in Ballet Dancers
Authors: Ogrinc Nina , Pavlović Monika , Šarabon Nejc
Published: May 2024

BACKGROUND: Ballet dancers are expected to use their bodies symmetrically during training, because dance movements are performed on both sides. However, there is a general belief that ballet training encourages the use of one side of the body more than the other. Frequent repetition
of a particular exercise can lead to body asymmetries and musculoskeletal injuries. The aim of this cross-sectional study was to investigate the presence of lower limbs and trunk muscle strength asymmetries in ballet dancers and secondly to assess whether there is a difference between professional
dancers and ballet students. METHODS: Ballet students (n=19) and professional ballet dancers (n=23) performed maximal voluntary isometric contractions of the trunk (flexion, extension, lateral flexion), hip (flexion, extension, adduction, abduction, external and internal rotation), knee (flexion,
extension) and ankle (flexion, extension) on isometric dynamometer. RESULTS: The results showed that the percentage of ballet dancers with contralateral muscle strength asymmetries >10% ranged from 22.5% (ballet students) to 31.6% (professional dancers). The percentage of ballet dancers
deviating by >10% from the normative maximum torque agonist/antagonist ratio ranged from 56.5% to 100%. A statistically significant difference between ballet students and professional ballet dancers was found in the trunk flexion/extension ratio (t(40) = –3 .55; p = 0.001; d = 0.55).
CONCLUSION: This study revealed strength asymmetries in the lower limbs and trunk in ballet dancers, both professionals and students. Further research is needed to develop appropriate complementary exercise to address and eliminate asymmetries in muscle strength in ballet dancers.

Amānāh is all religious duties or encumbrances covering worldly and hereafter matters which are addressed to humans. Without the value of Amānāh social and state life can be damaged, including life in a household. The concept of Amānāh that is built will not be separated from the culture and social influences of one's place of residence. In accordance with the term, the word Amānāh is taken from Islamic grammar and then adapted to the context of Indonesian society and has the meaning of being trustworthy. then the term Amānāh is attached to people who can be trusted. However, this concept is not yet operationally clear. Therefore, it is necessary to understand the meaning of the mandate both conceptually and operationally. All of this will be investigated and discussed later in this research, not only capturing the value of Amānāh from a conceptual point of view but will be explained operationally.The meaning of Amānāh in this study was built with a qualitative phenomenological approach from the main informants as housewives and from experts in various scientific fields related to the value of the Amānāh itself which is associated with household financial management. The various scientific fields are the field of Sharia economics, the field of Islamic religion, the field of psychology and the field of sociology.

Published: May 2024

The capacity to forecast the pandemic growth has been crucial in making decisions on how to combat and control COVID-19 spread in current and future waves of infection. Since the phenomenon was developed over time, we have analyzed the COVID-19 confirmed, recovered, and death cases in Indian provinces through time series analysis to comprehend the growth patterns of these cases. For a better explanation and prediction of COVID-19 dissemination, we have used the well-known ARIMA(Auto Regressive Integrated Moving Average) time series model. The COVID-19 cases from Jan 31, 2020, to Jan 30, 2022, having three waves of Alpha, Delta, and Omicron variants of SARS-CoV-2 were analyzed through time series regression models in India for all 28 states (provinces) and 8 union territories (directly federally governed territories). The analysis could aid in the development of more effective intervention programs and the mitigation of the current and future waves of the pandemic.

Fault Diagnosis for Power Grids Based on Stochastic Self-Regulating Algorithm Under Disaster-Causing Weather
Authors: Wang Tao , Liu Liyuan , Ying Ruixuan , Zhou Chunyu
Published: May 2024

In recent years, due to shifts in the global climate and environment, a variety of extreme weather events have become more frequent, resulting in numerous accidents. The increased occurrence of extreme weather not only poses risks to the functioning of the power grid but also impacts the accuracy of power grid fault diagnosis outcomes. By integrating research on power grid fault risks during extreme weather events, this study introduces weather data and self-check information to develop a fault diagnosis approach for the power grid based on a random self-regulating algorithm. The fault diagnosis method comprises two main components: Firstly, an analytical model for fault diagnosis is constructed using alarm data, weather information, and self-check data from the affected power outage area. Three types of self-adjusting trust factors are incorporated into the model to enhance its fault diagnosis capabilities in the context of extreme weather events. Subsequently, a random self-regulating algorithm is applied to optimize the model and generate a hypothesis regarding the fault. Through a simulation test on a sample calculation, the results demonstrate that the fault diagnosis method exhibits robust fault tolerance towards abnormal operation of protective devices and inaccuracies in alarm data.

Flood early warning systems (FEWS) play a crucial role in mitigating flood damage. To optimize their effectiveness, it is important to understand how people respond to warnings and prepare for flooding events. The key factors influencing social preparedness include (1) direct and (2) indirect experiences of floods and (3) trust in warnings. However, existing socio-hydrological models do not incorporate all these elements. To include these elements for social preparedness, we propose a stylized model that allows multiple regions to influence one another (i.e., regional interactions). We investigate the dynamics of social preparedness in a society composed of regions with varying infrastructure levels (e.g., levee heights) and explore strategies for developing a socially efficient FEWS. Numerical analyses reveal that in a society that has a region characterized by a low infrastructure level (i.e., a region with frequent floods), regional interactions lead to a pronounced cry wolf effect due to false alarms from other regions, diminishing social preparedness in the low-infrastructure region. These interactions also prevent a warning strategy that optimizes the natural science-based index (i.e., threat score) from maximizing social efficiency. Conversely, in a society that has a region characterized by a high infrastructure level (i.e., a region with infrequent floods), regional interactions enhance the efficiency of FEWS by improving social preparedness through indirect experiences with floods. These findings suggest that as regional heterogeneity increases, it becomes increasingly vital for forecasters to consider social aspects (e.g., people's experiences, trust, and interactions) when establishing a socially efficient FEWS.

This study analyzes how AI-enabled digital technologies including VR and AR have changed manner of travelers' experiencing in Uzbekistan. This study employs a logistic regression model with a binary logarithm to review the opinions of 207 international visitors representing a number of countries towards digital apparatus and how they impacted their vacation experience. The data was gathered for the period from the years 2014 to 2022 about the total international visitors and their average money they spent per person. Also, the tourists’ opinions about the influence of the AI tools in their traveling experience were polled. It is evident from the results that these elements act as the major determinants of tourists' largely positive attitudes toward digital services. Russian, Turkmen, Kazakhstan, Afghanistan and German, which stands out by having the highest probabilities of positive experience (88–93 percent). The model that has R-squared value of 48% argues that the number of visitors and how wealthy they are on average play roles as significant determinants of the willingness to support digital technology in the tourism business. This study gives us an insight into how AI-based digital tools can make a difference in a tourism trip and fosters a better understanding of the industry.

Published: May 2024

Background: This study compared laboratory risk and turn-around time (TAT) between sequence-based typing (SBT) and next-generation sequencing (NGS) for human leukocyte antigen (HLA) typing.
Method: Risk assessment utilized the risk priority number (RPN) score based on failure mode and effect analysis (FMEA) and a risk acceptability matrix (RAM) according to Clinical Laboratory Standards Institute (CLSI) guidelines (EP23-A). Total TAT was documented for the analytical phase, and hands-on time was defined as manual processes conducted by medical technicians.
Results: NGS showed a significantly higher total RPN score than SBT (1,171 vs. 465). NGS indicated higher mean RPN score, indicating elevated severity and detectability scores than SBT (RPN 26 vs. 19, P=0.001; severity 5 vs. 4, P=0.005; detectability 5 vs. 4, P<0.001, respectively). NGS required a greater number of steps than SBT (46 vs. 25 steps), all of which were acceptable for the RAM. NGS showed longer total TAT, total hands-on time, and hands-on time per step than SBT (26:47:20 vs. 12:32:08, 03:59:35 vs. 00:47:39, 00:05:13 vs. 00:01:54 hh:mm:ss, respectively).
Conclusions: Transitioning from SBT to NGS for HLA typing involves increased risk and extended TAT. This study underscored the importance of evaluating these factors to optimize laboratory efficiency in HLA typing.
Experiences of Independent Living among Female Youths after Leaving Out-of- Home Care in South Korea: A Phenomenological Study
Authors: Noh Dabok , Kim Eunyeong , Kim Goun
Published: May 2024

Youths in out-of-home care residing in alternative living arrangements in Korea must leave the placement by their 25th birthday. In the transition to independence from out-of-home care, they often encounter significant financial and psychological difficulties. This study employed a qualitative phenomenological methodology using Colaizzi’s phenomenological data analysis to extract, organize, and analyze the data. In-depth interviews were conducted with ten female youths living independently after being discharged from youth shelters. Unstructured and open-ended questions were asked to collect clear and sufficient descriptions regarding participants’ lived experiences of female youths after leaving out-of-home care. Our analyses revealed four themes in transitioning from out-of-home care to independent living related to their experiences of beginning to stand alone; becoming a grown-up suddenly; needing a helping hand to deal with the emptiness in life; and hope for the future. Out-of-home youths struggled and needed help from supportive policies and institutions to achieve financial, social, and psychological stability while becoming independent. These findings should encourage practitioners and policymakers to strengthen and expand tailored and long-term support systems for successful independent living for out-of-home youths in Korea.
The Paradox of Uncertainty: How Tolerance for Uncertainty Modulates Approach Motivation - Evidence from ERPs Experiments
Authors: Fei Dingzhou , Liu Yinrui , Zhang Wenqing
Published: May 2024

Background
Certainty has an important meaning for an individual, as it gives a sense of security and fulfillment. However, uncertainty occurs every day in real life, causing anxiety and aversion. Therefore, individuals take measures to cope with uncertain feelings. Previous studies have hinted at the important role of approach motivation in alleviating uncertainty and the possibility that loss of a sense of control may induce approach motivations and behaviors, but there is no clear empirical research demonstrating this mechanism. We explored the role of uncertainty in the induction of approach motivation and the moderating role of uncertainty tolerance.
Method
In the present study, we measured subjects' uncertainty tolerance trait, in addition to the classical forced-choice gambling task, and measured 20 subjects' brainwave changes in uncertain situations, using the lateralization of approach-motivated brain activity to test the above hypotheses using the FRN and the P300 as the response indexes.
Result
Subjects who received the feedback "+/-/?" in the gambling task were followed by the production of FRN in the right brain and then P300 in the left brain, and the peaks of the P300 wave in the "+" and "-" feedback cases were significantly lower than those of "?". In addition, the peak difference between the left and right brain P300 waves was significantly higher in individuals with low uncertainty tolerance than in those with low uncertainty tolerance.
Conclusion
We found that subjects experience significant uncertainty after making a high-risk versus high-reward choice and uncertainty is accompanied by approach motivation. After we grouped the subjects according to the level of uncertainty tolerance, we found that the difference between left and right brain P300 was significantly smaller in the high-tolerance group than in the low-tolerance group, suggesting that uncertainty tolerance plays a moderating role in uncertainty-induced approach motivation.
Slip Distribution of the 1946 Showa-Nankai Earthquake Estimated by Nonlinear Tsunami Inversion

Published: May 2024

To address the limitations of linear tsunami inversion, here, the Levenberg-Marquardt algorithm was applied to tsunami inversions, which allowed the use of nonlinear tsunami trace height data to estimate earthquake slip distributions. To the best of our knowledge, a completely nonlinear tsunami inversion has been used for the first time to investigate the source processes of historical earthquakes in which only tsunami trace heights are available. Using this inversion scheme and nonlinear long-wave equations, we estimated the slip distribution of the 1946 Showa-Nankai earthquake. The estimated slip distribution using only tsunami trace heights indicated a similar slip pattern to models previously proposed by linear tsunami inversions, although the amount of slip was substantially large. Another nonlinear inversion, which jointly used tsunami trace heights, tsunami waveforms, and crustal displacement data, imaged two slip asperities off Shikoku and the Kii Peninsula. The amount of slip in the asperities was still greater than that in the linear tsunami inversion analysis. However, it is still necessary to explain the tsunami trace heights. Our estimated earthquake magnitude was consistent with that obtained from the analysis of the seismic waveform inversion. The discrepancy in the estimated slip amount between the linear and nonlinear tsunami inversions may be related to uncertainties in the tsunami trace heights and/or tide gauge data.
