Principios de ordenación del crecimiento urbano propuesto en el Plan General de Palma: "urbanismo de marcha atrás" y revitalización de la ciudad existente para limitar el consumo de territorio
Authors: Górgolas-Martín Pedro
Published: September 2023

La organización espacial de las piezas de crecimiento urbano es uno de los contenidos fundamentales de todo Plan General. Ahora bien, hay que advertir que, en las circunstancias actuales caracterizadas por un preocupante sobredimensionamiento del suelo urbanizable consignado en el planeamiento municipal vigente, la incitación a su contracción ha de constituirse en un inexcusable ejercicio de ética territorial si se quiere evitar la propagación de la patológica dilución urbana que ocasionaría su desarrollo. Esta directriz contractiva guarda una estrecha vinculación con la apuesta por la renovación cualitativa de la ciudad existente, que debe actuar como estímulo para ejercitar una suerte de “urbanismo de marcha atrás” orientado a restringir el suelo clasificado como urbanizable al estrictamente necesario para acomodar las demandas que no han podido ser atendidas en el suelo urbano. El presente texto se destina a exponer las estrategias de ordenación desarrolladas por el Plan General de Palma para invertir las habituales “tendencias expansivas” que han caracterizado el planeamiento urbano impulsado en décadas precedentes.
La ciudad que queremos, los planes que necesitamos: ampliando los horizontes políticos del planeamiento urbano
Authors: Ezquiaga-Domínguez José María
Published: September 2023

El sistema de planeamiento español atraviesa una profunda crisis de legitimidad que afecta a sus dimensiones técnica, jurídica y social. En este artículo se analizan los fundamentos epistemológicos de esta crisis desde la perspectiva la formación histórica del planeamiento. Analizándose las consecuencias que el singular vínculo entre el plan como herramienta técnica de gobierno del territorio y como instrumento de regulación del estatuto de la propiedad del suelo tiene en la obsolescencia del sistema: sobrerregulación, burocratización y judicialización del planeamiento. El artículo formula una propuesta alternativa de reforma desde una concepción estratégica del plan municipal como herramienta de gobernanza espacial y plataforma de diálogo entre la sociedad civil y los poderes públicos, orientada a la implementación de una agenda renovada de objetivos para la transición urbana.
Effects of Positive Nursing Organizational Culture and Organizational Communication on Nurses’Job Embeddedness: Mediating Effect of Organizational Communication
Authors:   Korean Association of Health and Medical Sociology, Lee Sun Hee , Yu Mi
Published: September 2023

Purpose: This study aimed to identify the factors that affect job embeddedness (JE) in clinical nurses focusing on positive nursing organizational culture (PNOC) and organizational communication (OC), and to verify the mediating effect of OC in the relationship between PNOC and JE.
Methods: Participants were 150 clinical nurses working in a university hospital located in J city, Korea. Data were collected between 114 and 30 August in 2022, and analyzed with independent t-test t-test, one-way ANOVA, one-way ANOVA, Scheffé test, Pearson correlation coefficient, hierarchical regression analysis, and Baron and Kenny’s 3 paths using SPSS/WIN 25.0 program. The mediating effect was verified by Bootstrapping.
Results: Factors affecting JE were gender(β=.25, p=.002), OC (β=.61, p<.001), and PNOC (β=.44, p<.001). The total explanatory power of the variables was 52.8%. The OC had a full mediating effect on the relationship between PNOC and JE (B=.41, CI=.31~.52).
Conclusion: This study confirmed that PNOC and OC are important factors to improve the job embeddedness of nurses. Therefore, it is necessary to develop a program to increase communication within the organization, and strategies are needed to create a more positive organizational culture in the nursing organization.

Avian Taxonomic and Functional Diversity in Contrasting Habitats: A Comparative Study of Urban and Remote Forests in Arusha, Tanzania
Authors: Haule Leonard John , Kaking’o Emanuel Richard , Joseph Kerstin
Published: September 2023

Urbanisation globally transforms landscapes, impacting biodiversity significantly. In Arusha, Tanzania, rapid urban expansion accentuates the interplay between urbanisation and avian biodiversity. This study investigates urbanisation's influence on avian communities in two contrasting forested habitats: the urban "Themi River Forest" and the remote "Lake Duluti Forest." We explore taxonomic and functional avian diversity, elucidating underlying mechanisms. Taxonomic diversity analysis reveals "Lake Duluti Forest" with slightly higher species richness and "Themi River Forest" with a more even species distribution, reflecting urbanisation's influence. This aligns with global trends indicating reduced urban species richness due to habitat fragmentation. The urban forest, however, demonstrates avian adaptability to urbanised landscapes. Functional diversity analysis uncovers "Lake Duluti Forest" with greater functional richness, indicating a wider array of ecological roles. In contrast, "Themi River Forest" maintains comparable functional evenness, suggesting ecological balance despite urbanisation. Both forests exhibit distinct ecological niches, highlighting avian community flexibility. These findings hold significance for avian conservation and urban planning in Arusha and similar urbanising regions. Higher taxonomic diversity in remote forests underscores conservation importance. The urban forest showcases avian adaptability, emphasising green spaces in urban planning. Long-term conservation should protect both urban and remote forests, integrating strategies for avian habitat preservation and connectivity. This study advances understanding of urbanisation, forest type, and avian biodiversity's intricate relationship, offering insights for effective conservation in evolving urban landscapes
Directed retreat and navigational mechanisms in trail following Formica obscuripes
Authors: Freas Cody A. , Spetch Marcia L.
Published: September 2023

Ant species exhibit behavioural commonalities when solving navigational challenges for successful orientation and to reach goal locations. These behaviours rely on a shared toolbox of navigational strategies that guide individuals under an array of motivational contexts. The mechanisms that support these behaviours, however, are tuned to each species’ habitat and ecology with some exhibiting unique navigational behaviours. This leads to clear differences in how ant navigators rely on this shared toolbox to reach goals. Species with hybrid foraging structures, which navigate partially upon a pheromone-marked column, express distinct differences in their toolbox, compared to solitary foragers. Here, we explore the navigational abilities of the Western Thatching ant (Formicaobscuripes), a hybrid foraging species whose navigational mechanisms have not been studied. We characterise their reliance on both the visual panorama and a path integrator for orientation, with the pheromone’s presence acting as a non-directional reassurance cue, promoting continued orientation based on other strategies. This species also displays backtracking behaviour, which occurs with a combination of unfamiliar terrestrial cues and the absence of the pheromone, thus operating based upon a combination of the individual mechanisms observed in solitarily and socially foraging species. We also characterise a new form of goalless orientation in these ants, an initial retreating behaviour that is modulated by the forager’s path integration system. The behaviour directs disturbed inbound foragers back along their outbound path for a short distance before recovering and reorienting back to the nest.

Authors: Yoon Jonggeuk , Choi Yooncheol
Published: September 2023

This study aims to prepare countermeasures that prevent the spread of infectious diseases including malaria and African Swine Fever (ASF) in regions adjacent to the DMZ and border region between North and South Korea and propose exchanges and collaboration measures between North and South Korea against diseases. For this, we reviewed cases of inter-Korean cooperation promoted by the Korean government or local governments and related studies and examined collaboration and problem factors in health and medicine between North and South Korea. Additionally, rooted by the exchange model for border areas between East and West Germany, we suggest applicable measures in the inter-Korean border areas. We put forward proposals for the continuous and specific development of inter-Korean health and medical cooperation plan on the basis of establishing Committee on Border Areas and Agreement on Health and Medicine by supplementing the limitation of piecemeal approach and support at one-time in North-South Korea relations in the past. Additionally, the current study suggests the need for inter-Korean cooperation at the local government level for joint malaria prevention, and prevention of the spread of livestock infectious diseases.

ANALYSIS OF TAX ASSESSMENT BY ASSEMBLY AND PROPERTY DEVELOPMENT ACTIVITIES IN FRAGMENTED URBAN LANDS – GWANGJIN DISTRICT, SEOUL, SOUTH KOREA
Authors: Shin Seungwoo , Lee Yeonjae , Taltavull de La Paz Paloma
Published: September 2023

Due to the land readjustment project in Gwangjin District, Seoul, Korea, in the 1970s, Gwangjin was characterized as a single-family residential area for individual households. Over the following 40 years, the land-use situation changed dramatically, and ironically, there is now a too-fragmented residential area and very insufficient commercial areas. We employed a balanced panel data analysis. The data for this study were 24,177 parcel tax assessments and land assembly, split, zoning change, and property development activities over nine years from 2011 to 2019. We found that de facto land assembly would affect the tax assessment by delaying it a year more than it is when the development is approved, while formal land assembly did not. Development activity itself increased the assessment for that year only. Finally, formal land assembly in the commercial zone increased the assessment only for the following year, while property development in the residential zone increased the assessment for that year only. We recommend that the government provide land-assemblyfriendly policy incentives to allow for much larger property developments in both residential and commercial zones. The research on land and property development activities’ impact on tax assessment can provide a reasonable basis for the government’s tax assessment institution building.
Born to Be Wide: The Distribution of Wide Binaries in the Field and Soft Binaries in Clusters
Authors: Rozner Mor , Perets Hagai B.
Published: September 2023

Most stars, binaries, and higher-multiplicity systems are thought to form in stellar clusters and associations that later dissociate. Very wide binaries can be easily disrupted in clusters due to dynamical evaporation (soft binaries) and/or tidal disruption by the gravitational potential of the cluster. Nevertheless, wide binaries are quite frequent in the field, where they can sometimes play a key role in the formation of compact binaries and serve as tools to study key physical processes. Here we use analytic tools to study the dynamical formation of soft binaries in clusters and their survival as field binaries following cluster dispersion. We derive the expected properties of very wide binaries both in clusters and in the field. We analytically derive their detailed distributions, including the wide binary fraction as a function of mass in different cluster environments, binary mass functions and mass ratios, and the distribution of their orbital properties. We show that our calculations agree well in most aspects with the results of N-body simulations but show some different binary fraction dependence on the cluster mass. We find that the overall fraction of wide binaries scales as

∝

, where N
⋆ is the size of the cluster, even for non-equal-mass stars. More massive stars are more likely to capture wide companions, with most stars above 5 M
⊙ likely to capture at least one stellar companion, and formation of triples is found to be frequent.

(M
UV = −21.6), S5-z17-1, identified in James Webb Space Telescope (JWST) Early Release Observation data of Stephen’s Quintet. We do not detect the dust continuum at 866 μm, ruling out the possibility that S5-z17-1 is a low-z dusty starburst with a star formation rate of ≳30 M
⊙ yr−1. We detect a 5.1σ line feature at 338.726 ± 0.007 GHz exactly coinciding with the JWST source position, with a 2% likelihood of the signal being spurious. The most likely line identification would be [O iii]52 μm at z = 16.01 or [C ii]158 μm at z = 4.61, whose line luminosities do not violate the nondetection of the dust continuum in both cases. Together with three other z ≳ 11–13 candidate galaxies recently observed with ALMA, we conduct a joint ALMA and JWST spectral energy distribution (SED) analysis and find that the high-z solution at z ∼ 11–17 is favored in every candidate as a very blue (UV continuum slope of ≃−2.3) and luminous (M
UV ≃ [ − 24:−21]) system. Still, we find in several candidates that reasonable SED fits (Δχ
2 ≲ 4) are reproduced by type II quasar and/or quiescent galaxy templates with strong emission lines at z ∼ 3–5, where such populations predicted from their luminosity functions and EW([O iii]+Hβ) distributions are abundant in survey volumes used for the identification of the z ∼ 11–17 candidates. While these recent ALMA observation results have strengthened the likelihood of the high-z solutions, lower-z possibilities are not completely ruled out in several of the z ∼ 11–17 candidates, indicating the need to consider the relative surface densities of the lower-z contaminants in the ultra-high-z galaxy search.
High-resolution Chemical Abundances of the Nyx Stream

Published: September 2023

Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk, but its origin is unknown. Nyx could be the remnant of a disrupted dwarf galaxy, in which case the associated dark matter substructure could affect terrestrial dark matter direct-detection experiments. Alternatively, Nyx could be a signature of the Milky Way’s disk formation and evolution. To determine the origin of Nyx, we obtained high-resolution spectroscopy of 34 Nyx stars using Keck/HIRES and Magellan/MIKE. A differential chemical abundance analysis shows that most Nyx stars reside in a metal-rich ([Fe/H] > −1) high-α component that is chemically indistinguishable from the thick disk. This rules out the originally suggested scenario that Nyx is the remnant of a single massive dwarf galaxy merger. However, we also identify 5 substantially more metal-poor stars ([Fe/H] ∼ −2.0) whose chemical abundances are similar to those of the metal-weak thick disk. It remains unclear how stars that are chemically identical to the thick disk can be on such prograde, high-eccentricity orbits. We suggest two most likely scenarios: that Nyx is the result of an early minor dwarf galaxy merger, or that it is a record of the early spin-up of the Milky Way disk—although neither perfectly reproduces the chemodynamic observations. The most likely formation scenarios suggest that future spectroscopic surveys should find Nyx-like structures outside of the solar neighborhood.
Sensitivity of He Flames in X-Ray Bursts to Nuclear Physics
Authors: Chen Zhi , Zingale Michael , Eiden Kiran
Published: September 2023

Through the use of axisymmetric 2D hydrodynamic simulations, we further investigate laterally propagating flames in X-ray bursts (XRBs). Our aim is to understand the sensitivity of a propagating helium flame to different nuclear physics. Using the Castro simulation code, we confirm the phenomenon of enhanced energy generation shortly after a flame is established by adding 12C(p, γ)13N(α, p)16O to the network, in agreement with the past literature. This sudden outburst of energy leads to a short accelerating phase, causing a drastic alteration in the overall dynamics of the flame in XRBs. Furthermore, we investigate the influence of different plasma screening routines on the propagation of the XRB flame. We finally examine the performance of simplified spectral deferred correction, a novel approach to hydrodynamics and reaction coupling incorporated in Castro, as an alternative to operator splitting.
What You Don’t Know Can Hurt You: Use and Abuse of Astrophysical Models in Gravitational-wave Population Analyses
Authors: Cheng April Qiu , Zevin Michael , Vitale Salvatore
Published: September 2023

One of the goals of gravitational-wave astrophysics is to infer the number and properties of the formation channels of binary black holes (BBHs); to do so, one must be able to connect various models with the data. We explore benefits and potential issues with analyses using models informed by population synthesis. We consider five possible formation channels of BBHs, as in Zevin et al. (2021b). First, we confirm with the GWTC-3 catalog what Zevin et al. (2021b) found in the GWTC-2 catalog, i.e., that the data are not consistent with the totality of observed BBHs forming in any single channel. Next, using simulated detections, we show that the uncertainties in the estimation of the branching ratios can shrink by up to a factor of ∼1.7 as the catalog size increases from 50 to 250, within the expected number of BBH detections in LIGO–Virgo–KAGRA's fourth observing run. Finally, we show that this type of analysis is prone to significant biases. By simulating universes where all sources originate from a single channel, we show that the influence of the Bayesian prior can make it challenging to conclude that one channel produces all signals. Furthermore, by simulating universes where all five channels contribute but only a subset of channels are used in the analysis, we show that biases in the branching ratios can be as large as ∼50% with 250 detections. This suggests that caution should be used when interpreting the results of analyses based on strongly modeled astrophysical subpopulations.
Screening Preeclampsia and the Role of Low Dose Aspirin for the Prevention of Preeclampsia
Authors: Putra Wayan Artana
Published: September 2023

Preeclampsia is one of the leading causes of maternal morbidity and can affect fetal conditions such as inhibition of intrauterine growth, premature labor, placental abruption, fetal distress, and, worst of all, intrauterine fetal death. In contrast to the decreasing incidence of pregnancies with infection, preeclampsia did not decrease significantly during the past two decades. Prevention of preeclampsia is an effort that is currently being intensively carried out to reduce morbidity and mortality of pregnant women. Prophylactic administration of low-dose aspirin (81 mg/day) is recommended in women with a high risk of preeclampsia. It should be started between 12 weeks of gestation to 18 weeks (optimal before 16 weeks). Aspirin has been shown to be safe for the mother and the fetus during pregnancy. Treatment with aspirin also did not increase the risk of developing congenital malformations and had no adverse effect on fetal development or bleeding complications during the neonatal period.

AIM: The objectives of this study were to perform a systematic literature review based on studies that compare unilateral and bilateral pedicle screw fixation (PSF) in lumbosacral spine fusion to provide recommendations for the treatment of degenerative diseases of the spine, to identify studies with a more complete evidence base, and to identify possible limitations in available literature sources that require further research.
METHODS: A literature search was conducted in PubMed, Embase, and the Cochrane Library to identify studies that compare unilateral versus bilateral PSF versus interbody implant placement used the treatment of degenerative diseases of the lumbosacral spine. The study included meta-analyses that met the inclusion criteria. The quality of meta-analyses was evaluated with a measurement tool to assess systematic reviews (AMSTAR) score and the most relevant meta-analysis was determined by applying the Jadad algorithm.
RESULTS: Twelve studies fulfilled the eligibility criteria and were included in the study. The results of AMSTAR score ranged from 6 to 9, based on the results, four meta-analysis can be assigned to “middle” category and remained 8 to “upper” category. According to the results obtained, there was no significant difference between unilateral and bilateral PSF; however, unilateral fixation had advantages in the duration of surgical treatment and intraoperative blood loss.
СONCLUSION: According to this systematic review, unilateral PSF is an effective fixation method in the formation of lumbosacral spine fusion and has advantages in reducing the duration of surgical treatment and intraoperative blood loss compared to bilateral PSF.
The Efficacy of Sildenafil in Children with Uni-Ventricle Congenital Heart Disease Post Bidirectional Cavopulmonary Shunt: An Evidence-Based Case Report
Authors: Batubara Edwin Adhi Darmawan , Bonita Angela , Hamid Umar Abdul , Sembiring Aditya
Published: September 2023

BACKGROUND: Univentricular congenital heart disease (CHD) is an anatomical heart defect where one of the  ventricles does  not  develop. Management of  univentricular defects  is  performed gradually; bidirectional cavopulmonary shunt (BCPS) is one of the surgical approaches conducted before the definite treatment in the Fontan procedure. Therefore, the average rate of pulmonary artery pressure and vasculature resistance is critical factors in determining good post-surgical outcomes. However, studies exploring the evidence that sildenafil administration can reduce pulmonary pressure in patients with univentricular defects are currently limited.
AIM: This evidence-based case report aims to investigate whether sildenafil administration toward post-BCPS patients reduces mean pulmonary  artery pressure (mPAP) and pulmonary vascular resistance (PVR) before undergoing the Fontan procedure.
METHODS: Available evidence was screened through four databases in  PubMed, Cochrane, Embase, and ProQuest on October 9, 2022. The keywords used were (((((single Ventricle) OR univentricular heart) AND BCPS) OR Glenn) AND sildenafil) AND hemodynamic. A result of three cohorts and one clinical trial was identified and critically appraised.
RESULTS: Analytical testing of the two studies by Park I and Jeremiasen et al. shows that sildenafil significantly reduces mPAP from 19.5 ± 5.5 mmHg to 14.3 ± 3.0 mmHg (p = 0.023) and from 19 mmHg (SD = 3) to 14 mmHg (SD = 2) (p < 0.01). The studies from Hill KD and Mori et al. illustrate that sildenafil significantly reduces the PVR index by as much as 24% (p < 0.01) and from 3.2 ± 0.5 wood unit to 1.6 ± 0.6 wood unit (p < 0.0001).
CONCLUSION: The administration of sildenafil decreases pulmonary artery pressure and vasculature resistance in post-BCPS pediatric patients, allowing patients to undergo the Fontan procedure.

The current cross-sectional descriptive study was performed to determine the effect of young adults' attitudes regarding social gender roles on perceived social support level in health behaviors. Participants comprised 209 young adults aged 18 to 21 years. Data collection tools included a sociodemographic characteristics form, the Gender Roles Attitude Scale, and Child and Adolescent Social Support Scale for Healthy Behaviors (CASSS-HB). Data were analyzed using percentile, correlation, and regression analysis. A significant positive correlation was found between total CASSS-HB score and the egalitarian gender role subdimension of the Gender Roles Attitude Scale. It was determined that participants with an egalitarian perspective toward gender roles had increased levels of social support in health behaviors. [

We aim to investigate an integro-differential inclusion using a novel computational approach in this research. The use of quantum calculus, and consequently the creation of discrete space, allows the computer and computational algorithms to solve our desired problem. Furthermore, to guarantee the existence of the solution, we use the endpoint property based on fixed point methods, which is one of the most recent techniques in fixed point theory. The above will show the novelty of our work, because most researchers use classical fixed point techniques in continuous space. Moreover, the sensitivity of the parameters involved in controlling the existence of the solution can be recognized from the heatmaps. For a better understanding of the issue and validation of the results, we presented numerical algorithms, tables and some figures in our examples that are presented at the end of the work.

Published: September 2023

Objectives: The purpose of this study was to determine factors associated with non-vaccination against coronavirus disease 2019 (COVID-19) among the Venezuelan immigrant population residing in Peru.Methods: A cross-sectional study was conducted using data obtained from the Second Survey of the Venezuelan Population Residing in Peru in 2022. The dependent variable was vaccination status against COVID-19. The independent variables included socio-demographic, economic, and migratory characteristics of the included population. Crude and adjusted generalized linear Poisson-family models were used to calculate prevalence ratios with 95% confidence intervals (CIs).Results: A total of 7739 Venezuelan migrants aged 18 years or older were included. The proportion of non-vaccination against COVID-19 was 5.7%. Regarding associated factors, unemployment (adjusted prevalence ratio [aPR], 1.31; 95% CI, 1.04 to 1.65) was linked to an increased likelihood of not being vaccinated against COVID-19. In contrast, women (aPR, 0.76; 95% CI, 0.61 to 0.95), possessing a migration permit (aPR, 0.41; 95% CI, 0.31 to 0.54), and having health insurance (aPR, 0.47; 95% CI, 0.27 to 0.81) were associated with a decreased likelihood of being unvaccinated.Conclusions: The primary governmental and non-governmental institutions responsible for supporting and protecting the Venezuelan migrant and refugee population should improve vaccination access by issuing migration permits and providing health insurance.

Objectives: Diabetes mellitus (DM) is a serious public health issue that places a heavy financial, social, and health-related burden on individuals, families, and healthcare systems. Self-reported health-related quality of life (HRQoL) is extensively used for monitoring the general population’s health conditions and measuring the effectiveness of interventions. Therefore, this study investigated HRQoL and associated factors among patients with type 2 DM at a primary healthcare center in Indonesia.Methods: A cross-sectional study was conducted in Klaten District, Central Java, Indonesia, from May 2019 to July 2019. In total, 260 patients with DM registered with National Health Insurance were interviewed. HRQoL was measured with the EuroQol Group’s validated Bahasa Indonesia version of the EuroQoL 5-Dimension 5-Level (EQ-5D-5L) with the Indonesian value set. Multivariate regression models were used to identify factors influencing HRQoL.Results: Data from 24 patients were excluded due to incomplete information. Most participants were men (60.6%), were aged above 50 years (91.5%), had less than a senior high school education (75.0%), and were unemployed (85.6%). The most frequent health problems were reported for the pain/discomfort dimension (64.0%) followed by anxiety (28.4%), mobility (17.8%), usual activities (10.6%), and self-care (6.8%). The average EuroQoL 5-Dimension (EQ-5D) index score was 0.86 (95% confidence interval [CI], 0.83 to 0.88). In the multivariate ordinal regression model, a higher education level (coefficient, 0.08; 95% CI, 0.02 to 0.14) was a significant predictor of the EQ-5D-5L utility score.Conclusions: Patients with diabetes had poorer EQ-5D-5L utility values than the general population. DM patients experienced pain/discomfort and anxiety. There was a substantial positive relationship between education level and HRQoL.
