„Jestem lilią Szaronu, lotosem rozkwitłym w dolinie” (Pnp 2,1–2). Wymowa florystycznej metafory w odniesieniu do oblubienicy z Pieśni nad pieśniami
Authors: Jasnos Renata
Published: September 2024

Artykuł podejmuje problem interpretacji terminów florystycznych (lilia, lotos) zastosowanych do opisu oblubienicy w Pieśni nad pieśniami (2,1–2). Problem wynika z trudności rozpoznania gatunku wymienionych w języku hebrajskim dwóch nazw kwiatów. Różne przekłady tych terminów od starożytności po czasy współczesne ilustrują tę trudność. Tymczasem symbolika różnych gatunków kwiatów może być odmienna.
Celem opracowania jest ponowne odczytanie i interpretacja symboliki florystycznej fragmentu Pnp 2,1-2. Aby osiągnąć zamierzony cel, przeprowadzona została analiza leksykalna zastosowanych terminów w ich kontekście literackim. Dodatkową pomocą posłużyły dane z zakresu botaniki i geografii uprawy wyżej wymienionych roślin. Odczytanie znaczenia symboliki rozpoznanych roślin zostało przeprowadzone w odniesieniu do szerszego kontekstu kulturowego jej zastosowania (w Egipcie, w świątyni jerozolimskiej).
Analizy prowadzą do wniosku, że zastosowano symboliczne, znaczące nazwy, które niosą w pierwszym rzędzie konotacje płodnościowe. Starożytni podziwiali nie tylko dziewicze piękno kobiety, ale fascynowała ich tajemnica płodności i życia. Obraz lilii i lotosu odniesiony do oblubienicy w Pnp rozwija symbolikę, która może być odczytana jako aluzja nawiązująca do Ewy jako „Matki żyjących” z Rdz 3,20.

Authors: Abass Hammed Anuoluwapo , Oyewole Olawale Kazeem , Aphane Maggie
Published: September 2024

In this paper, motivated by the works of Akbar and Shahrosvand [Filomat {\bf 32} (2018), no.\ 11, 3917-3932], Ogbuisi and Izuchukwu [Numer. Funct. Anal. Optim. {\bf 41} (2020), no.\ 2, 322-343], and some other related results in the literature,
we introduce a Halpern iterative algorithm and employ a Bregman distance approach for approximating a solution of split equality monotone variational inclusion problem and fixed point problem of Bregman relatively nonexpansive mapping in reflexive Banach spaces.
Under suitable condition, we state and prove a strong convergence result for approximating a common solution of the aforementioned problems.
Furthermore, we give an application of our main result to variational inequality problems and provide some numerical examples to illustrate the convergence behavior of our result.
The result presented in this paper extends and complements many related results in literature.

Authors: Amster Pablo , Kuna Mariel P. , Santos Dionicio
Published: September 2024

A formal framework for the analysis of Hopf bifurcations for a kind of delayed equation with $\varphi$-Laplacian and with a discrete time delay
is presented, thus generalizing known results for the sunflower equation given by Somolinos in 1978.
Also, under appropriate assumptions we prove the
gradient-like behavior of the equation which, in turn, implies the
non-existence of nonconstant periodic solutions. Our conditions improve
previous results known in the literature for the standard case $\varphi(x)=x$.
Local Agglomeration and Household Mortgage Debt
Authors: Chen Fengqin Freya , Saffar Walid , Shang Longfei
Published: September 2024

Using detailed household data, we find that households working in locally agglomerated economies have high mortgage loans and are more likely to have mortgage loans. Channel testing shows that local agglomeration increases housing and mortgage demand as well as mortgage supply. The increase in mortgage loans is driven by purchases of larger houses and smaller down payments. Mechanism analyses document that local agglomeration affects mortgage loans by increasing career upward potential and providing downside protection. Specifically, we find that the impact of local agglomeration is stronger for skilled employees with enhanced prospects. In addition, local agglomeration weakens the negative relation between unemployment and mortgage loans, which supports the downside-protection role of local agglomeration. These results hold under instrumental variables analysis, difference-in-difference analysis, and a set of robustness checks. Overall, our findings highlight the importance of local labor market composition in household mortgage debt.

The purpose of this study was to identify characteristics of traditional nursing in Chosun Dynasty. Various health care activities introduced in the classic works have been examined for the identification of major characteristics of nursing in traditional society. A study of the classical works revealed the following aspects of nursing care were evident : environment, diet, exercise, bedside care, medication and fetal discipline. In their treatment, it became clear that the most salient feature of traditional nursing in Chosun dynasty is the humanistic nature of care. Another distinctive feature of traditional nursing is its notion of empathic care.Loyalty is another key principle of traditional nurs ing in Chosun dynasty. However, the empathic principle was always practiced in keeping with the principle of loyalty. The principle of mean and confirmity with nature appear to have been a basic guideline for nursing practices in traditional society.Some nursing activities in traditional society are shamanistic, particularly the prayers offered for the recovery of a family member's illness and the protection of all family members from evil spirits.These shamanistic rituals imply considerable measures of empathy, loyalty, and filial piety according to Confucian tenets.

Authors: Won Jeong Sook
Published: September 2024

The final destination of the mental health care is to make the patient recover his productive social skill, forcusing on his social rehabilitation, with the basic goal of avoiding unnecessary hospitalized treatment and removing of the symptom.It also aims to strengthen the community-based mental treatment, avoiding hospitalized treatment as much as possible, thus balancing and connecting the two strategies. For hospitalized treatment should be practised only in necessary cases and partial hospitalization should be activated. As for hospitalization facilities, they should be restricted in size suitable for the treatment of patient.Mental Health Law is the nation's effort to pro vide best treatment for the patients who cannot make effort to enhance the quality of life with proper treatment for himself. In this task Psychiatric-Mental Health Nurse Practitioner(PMHNP) plays an important role, together with mental illness specialist, in prevention and treatment of mental ill-ness, mental health consulting as well as social re habilitation of the patient. In this sense the role of PMHNP as a highly specialized personnel, must not be underestimated.In this study, the researcher tries to suggest how to widen the role of PMHNP and how to prepare for that. To approach the goal of this research, this the sis studies closely the role of the nurse, diving it into three一1) role in general, 2) role in particulat in each section, 3) role as a case manager—and suggests its orientation. It also suggests the nursing management of chronic mental illness patient and the esti mation and tasks of mental health nursing.The suggestions about the impending tasks of community-based mental health care in this thesis are hoped to contribute to settling the activity of PMHNP who is inevitable for the mental health of the community people.

Published: September 2024

It is important for psychiatric nurses to understand client*s behavior thus developing effective relationships between clients and nurses. This study was conducted to designing an assessment tool, which is helpful to nurses in the psychiatric mental-health setting. This tool, based on Roy’adaptation model, is adopted the various nursing setting and validates the applicability. The research was doing from Dec. 1995 to Jan. 1997. During the first stage, this tool was designed through literature re view and nursing history form, using one national psychiatric hospital, five university affiliated hospital, and a neuropsychiatric ward. Secondly, the tool was distributed to psychiatric nurses, who were asked to fill out the form and write the strength and weakness after having been interviewed. The last stage, incorporated a case study using this tool. The evaluation of this tool helped the researcher gather much of data required to make a specific nursing diagnosis, Finally, a psychiatric nursing assessment tool was designed to identify the four adaptation levels. The positive responses included the ability of the nurses to ask specific questions and guide the direction of interview, systematically by four adaptive modes. A number of nurses stated in the evaluation meeting that this tool helped them to get to know the patients more fully and to broaden their perspective in nursing assessment. The negative responses were : the tool was too long to provide an effective interview and was not clear regarding the boundaries of the three modes : self-care, interdependence, and role function modes.Consequently, the redundant items was partially excluded. The check list form was included in physiological mode for time and anti-psychotic drug’side effects which caused severe trouble in therapeutic setting was added in physiological mode neurological. The self-concept mode items including mental status examinations, have a high relevance with mental health assessment. Finally, further study is needed to increase the effectiveness and adequacy of this tool.

Korean economic development has proceeded at the rapid rate of in the past two decades with neglect to some areas of human development, especially in the case of mental illness. But the government has belatedly recognized the importance and urgency of welfare and health programmes to cope with increasing problems.Mental health problems are more serious among the economically underprivileged than others. Because of large portion of mental patients from the economically underprivileged segment are at home without proper treatment or care.Thus it is imperative to develop easily assessible, cost-effective alternatives that would offer effective mental health care as well as useful social rehabilitation programmes. The government enacted the National Mental Health Law in December 1995. This project will assist to clarify the appropriate roles of the most effective care system. 20 nurse practitioners began a study on voluntary basis to assess the patients and their family with assessment tool which developed by research members. After that, managed the 46 patients and their families through telephone or home-visiting, day care center programmes (such as social skill training, group therapy, movement therapy, art therapy) and counselling, refering hospital and family support group.The goals of research is to strengthen the capacity of psychiatric mental health nurse practitioners to undertake home and community-based mental health care services through various training programmes and expected outcome is this programme will be developed continuously and implemented to another community mental health center.Lastly, the cost-effective study of communitybased mental health care will have bee nundertaken with realistic data provided by the pilot programme policy recommendations prepared for the Ministry of Health and Welfare.

Concept Analysis on Powerlessness
Authors: Kim Hyun Mi , Nam Young Hwa , Lee Hae Kyung , Jeon Sung Ju , Chung Bokyae
Published: September 2024

Powerlessness, as one among the many important concepts in nursing science, has a physically or mentally bad effect on an individual. A continued powerlessness leads to anxiety, depression, hopelessness and if one does not have a successful readaptation process, and finally get into a powerlessness - hopelessness cycle that could lead to a fatal conclusion. Therefore, decreasing powerlessness is becoming a very important nursing objectives.Nurses must help clients to avoid or lessen their powerlessness and detect which patients could be vulnerable to the diagnosis related to powerlessness, design strategies to solve nursing problems and be able to evaluate the results.But there are some differences in defining powerlessness among researchers. And also the meaning of powerlessness and helplessness are used interchangeably. We need to present the meaning of powerlessness which is more definite and able to share among scholars.To accomplsh this task, we conducted our own research on the topic of powerlessness. Analysis was done according to a series of process described by Walker and Avant (1988).In result, we looked into the powerlessness concept through the existing uses, and decided on adopting the repeated characteristics like follows as attributes :• Perceived loss or lack of control over what happens to oneself and one's environment.• inability to perform physical function for oneself - inability to perform usual roles, have no help and financial ability • lack of knowledge and lack of motivation Precise concept analysis of powerlessness gives a more comprehensive understanding about the phenomenon, futher, it is viewed as a basic data to develop nursing intervention which is proper and effective.

This paper explores what research is available regarding the choice and comparison of information/cyber security standards. It provides a snapshot of the security standards landscape at the start of 2024. Issues relating to development and adoption of security standards are examined, illustrated using inconsistencies in language regarding three key terms: availability, integrity, and confidentiality.
Design and performance of a dual-band plasmonic perfect absorber for infrared refractive index sensing
Authors: Zahra Tazeen , Mohemine M. Abdul , Syed Aqeel A. , Liu Fengguang , Ali Wajid , Muhammad Zahir
Published: September 2024

In this study, we introduce what we believe is an innovative design for a plasmonic perfect absorber (PPA) that is based on half-cut disk resonator metamaterials. This design exhibits remarkable stability and versatility, demonstrating effective functionality across a wide range of incident angles for both transverse electric (TE) and transverse magnetic (TM) polarization. The distinct operational characteristics of the PPA are highlighted by the presence of two corresponding absorption peaks at wavelengths of 870 and 1599 nm, where it achieves outstanding maximum absorption rates of 98.99% and 97.5%, respectively. The design’s ultra-narrow resonance peaks are indicative of its high-quality factors, which are vital for enhancing sensitivity in plasmonic sensory applications. This characteristic renders our PPA an exceptional candidate for refractive index (RI) sensing, where precision is critical. The dual-band perfect absorber (PA)-based sensor demonstrates significant RI sensitivity, with values approximately equal to 365 nm/RIU at the first absorption peak and 733 nm/RIU at the second. Our findings elucidate the exceptional potential inherent in this novel dual-band perfect absorber design. The versatility and efficiency across varied applications not only contribute to the existing body of knowledge but also pave the way for future advancements in plasmonic sensor technologies and metamaterial research.
Ultra-compact silicon nitride dual-polarization mode converter for visible light demonstrated on a thinned 320  nm silicon wafer

Published: September 2024

A dual-polarization higher-order mode converter is proposed for visible light, which operates within the (400–700) nm range, to enhance data capacity in on-chip visible light communication systems. The proposed structure is optimized at wavelengths of 410 nm, 560 nm, and 660 nm to cover the entire visible spectrum. These three optimized designs, in particular, have an intrinsic property wherein they can be optimized to simultaneously convert both polarized fundamental (TE0) and fundamental (TM0) modes to the second higher-order (TE2) and (TM2) modes, providing significant advantages for hybrid multiplexing systems like PDM-MDM and PDM-WDM schemes. The mode converters are constructed on a silicon nitride waveguide. This waveguide is etched and filled with silicon dioxide material to create two dielectric substrips, followed by an additional rectangle shape etched using the same process into the propagating waveguide. This alteration enhances insertion loss and diminishes crosstalk to the fundamental mode. The devices achieve a broad operating bandwidth of approximately 100 nm while maintaining a compact footprint of only 1µm×1.754µm for the entire device at the center wavelength of 560 nm. Upon optimizing the suggested structure, a TE0-to-TE2 mode converter with a modal conversion efficiency of 94% is designed at the wavelength of 410 nm. The insertion loss is 0.6025 dB, and the crosstalk with the transverse electric fundamental mode TE0 is 35 dB. The reported devices feature a straightforward structure with low insertion loss and minimal crosstalk.

Published: September 2024

Multispectral imaging is an emerging technology that captures multiple images across a wide range of wavelengths, including UV, visible, and IR, and even further into the electromagnetic spectrum well beyond the capabilities of the human eye. Hyperspectral imaging expands this idea to capture hundreds of bands of continuous spectra of objects with better spectral resolution but requires expensive optical components and complicated systems such as diffraction gratings, prisms, etc. The optical system for multispectral imaging technology can be made simpler and more compact. This paper presents a simple six-band multispectral imaging system based on the Fabry–Perot multilayer, which can not only generate color images but also reconstruct the spectrum data, showing promise in applications such as precision agriculture, color imaging, and remote sensing.

En 2022 se cumplieron 30 años de la publicación de «Un país al margen de la ley» de Carlos Nino, este artículo revisa ese trabajo del autor argentino a la luz de los enfoques institucionalistas del desarrollo que se instalaron como principal corriente de pensamiento desde la década de 1990 y que continúan teniendo una fuerte influencia. La revisión que se realiza comparte algunos puntos de partida de «Un país al margen de la ley» pero también ofrece una visión crítica del trabajo y de algunas ideas institucionalistas. La idea central del trabajo es que la descripción que realiza Nino sobre la anomia en Argentina (extensible en la mayoría de los casos al resto de América Latina) no es tanto un producto sociológico o de raigambre histórica como un problema «de la ley». Por lo tanto, las miradas para superar la anomia deberían orientarse a los modelos de discusión y producción legislativa. Finalmente, el artículo realiza una breve reseña de la situación de la Argentina de hoy, evaluando qué ha cambiado desde que Nino escribiera el libro del que se ocupa este trabajo.
Addressing Mental Health Disparities: A Geographic and Economic Analysis of Mental Health Service Gaps in Houston (Poster)
Authors: Kelly Damien , Carmack Chakema
Published: September 2024

This study explores "mental health deserts"—areas with insufficient mental health care providers—in Houston, Texas. Using the Distressed Community Index (DCI) to identify economically disadvantaged areas and sampling over 3,000 licensed therapists from Psychology Today’s database, the research maps mental health service availability across 96 zip codes in Houston. A food desert model is applied as a framework to compare mental health service access in these regions, analyzing factors such as the number of professionals, demographics, education levels, and poverty rates. Analysis of Variance (ANOVA) examines the relationship between these variables and the classification of zip codes as mental health deserts. Preliminary findings indicate that low-income areas with higher DCI scores often lack adequate mental health resources, highlighting a need for targeted interventions. The study aims to inform policymakers and healthcare providers about the urgent need for enhanced mental health infrastructure in economically distressed communities.

The article is devoted to improving the quality of designing technological processes based on their optimization. The technological process consists of many stages – the development of a general sequence of operations, the formation of installations, transitions, refinement and specification of technological parameters, etc. When forming a mathematical model of the process to improve the efficiency of each of its stages, it is necessary to correctly select the order of these stages and set the target functions necessary for them, taking into account the existing restrictions. At the same time, cost and performance parameters must be taken into account without fail. The article proposes a technique for the formation of a technological process based on its mathematical model, which makes it possible to quantify the processing error in order to determine the best variant of a technological transition and operation.

The influence of the grade of the material from which the magnetic conductors are made on the power characteristics of the magnetic system and magnetic coupling with highly coercive permanent magnets Nd–Fe–B with a residual magnetic induction of 1.22 T is considered. The material of the magnetic conductors is steel 15, steel 09Г2C and corrosion-resistant steel 08Х22H6T. On average, in the range of air gaps between sections of the magnetic system from 4 to 10 mm, the decrease in the specific shear force with magnetic conductors made of corrosion-resistant steel 08Х22Н6T, relative to magnetic conductors made of steel 15 is 17.88 %. The increase in the specific shear force with magnetic conductors made of steel 09Г2C relative to magnetic conductors made of steel 15 depends on the value of the air gap between the sections of the magnetic system and varies from 2.53 to 11.81 %.

Detection of defects on the rolling surface of wheelsets, the formation of which occurs in the process of operation, is becoming the most important task of ensuring safety on railroad transport, the importance of which is becoming greater in connection with the growth of rolling stock speeds and increasing freight traffic. The development of defects in wheel pairs leads to destruction of the running parts of the rolling stock and wear of the rail tracks, and, as a consequence, an accident (railway derailment). One of the most significant characteristics of the condition of the tracks and rolling stock are the pressure of the wheel on the rail, and the load that occurs in the rail. Existing methods for identifying defects are reduced to measuring the deflection of the rail and weight measurement, which is used to judge the excess load created by the wheels of the rolling stock on the rail. This paper describes magnetoelastic methods for monitoring the condition of elements of railway tracks and rolling stock in front of existing non-magnetic ones. The advantage of magnetoelastic methods is that the determination of stresses in the object under study occurs directly, and not indirectly, because stress control is carried out by turning on the object under study as an element of the measurement circuit, which gives the most reliable ideas about the stresses arising in the object.

The paper discusses the measurement of amplitude characteristics parameters of quadripole networks that is one of important and relatively new areas of measurement technology. In this paper, this aspect is considered in relation to discrete methods for measuring parameters of amplitude characteristics using digital procedures for generating and converting test signals. It is shown that, in contrast to the constant one, with a discrete modulation law it is possible to weaken the influence of transient processes and dynamic distortions of the test signal in the studied quadripole network, which helps to significantly increase the sensitivity of analyzers of the amplitude characteristics of quadrupole networks.

In the modern world, there is mass production of electronic equipment, microelectronics and electronic components. To reduce the number of defects and refine production processes, it is imperative to control the quality of manufactured products at all stages of production. Of all the non-destructive methods of installation quality control, the most effective is radiation non-destructive testing, namely X-ray tomography. This article provides an overview of equipment designed for X-ray tomography and laminography used in quality control of soldering and installation of electronic equipment. The equipment under consideration makes it possible to identify defects that arise when the technological process of electronic equipment production is disrupted, including poor-quality soldering when installing microcircuits in BGA packages.
