Groundwater Detection Using Resistivity at Nubutautau Village in Viti Levu in Fiji
Authors: Maharaj Ronald , Kumar Sushil , Rollings Nicholas , Antoniou Andreas
Published: November 2023

A geophysical method, electrical resistivity tomography, was applied to identify potential groundwater-bearing zones around Nubutautau village on Viti Levu island, Fiji. Apparent resistivity data of the subsurface were collected through an electrode assembly along survey lines by injecting current into the subsurface using an ABEM Terrameter LS2. The apparent resistivity data were inverted using Res2DINVx64 software to produce the final electrical resistivity through an iterative process to compare the resistivity of layers and draw analogical hydrogeological results. Analysis revealed the presence of two potential groundwater-bearing zones as potential targets for future drilling. The two targets indicated the presence of potentially saturated vertical fractures through which infiltrating rainwater percolates through the volcanic rock towards a deeper basal aquifer. The identification of the two potential targets demonstrated great potential of this geophysical technique to effectively inform drilling operations. A scientific approach can increase the successful delivery of water security interventions in remote, drought-prone communities of the Pacific.
Sub-Shrub Components Change the Soil Water Storage Response to Daily Precipitation and Air Temperature in the Loess Plateau

Published: November 2023

Soil water shortage has become a severe issue in ecological restoration and sustainable development in the Loess Plateau, facing the challenges of climate change and vegetation restoration. This study monitored the soil water content in surface soil (0–40 cm) with different sub-shrub component treatments, including the natural condition (NC), the canopy plus the roots (CR) and only the roots (OR), to analyze the change in soil water storage (∆W) and its response to precipitation (P) and air temperature (Ta) on a daily scale. P was the main factor controlling the daily ∆W, contributing 49–52% to the variation in the daily ∆W, and Ta only explained 6–21% of the variation. Minimum P amounts of 0.74–1.12 mm and maximum Ta of 29.09–32.00 °C were the thresholds required to increase soil water storage (W). Sub-shrub components showed significant influences on soil water conservation. We found that the ∆W hierarchy for each sub-shrub treatment was NC (1.73 mm) > CR (0.71 mm) > OR (0.56 mm) on rainy days and NC (−0.53 mm) < CR (−0.36 mm) < OR (−0.06 mm) on no-rain days. Additionally, the hierarchy of the rainwater retention rate was NC (26.43%) > OR (13.71%) > CR (4.58%). Thus, a canopy could increase infiltration and hugely consume soil water at the same time, while litter could weaken or offset the canopy’s effects and the roots promote infiltration with little evaporation loss.

Published: November 2023

Drought has significant impacts on both society and the environment, but it is a gradual and comprehensive process that affects a region over time. Therefore, non-structural measures are necessary to prepare and respond to the damage caused by drought in a flexible manner according to the stage of drought. In this study, an AI-based water demand prediction model was developed using deep neural network (DNN) and long short-term memory (LSTM) models. The model was trained from 2004 to 2015 and verified from 2016 to 2021. Model accuracy was evaluated using data, with the LSTM model achieving a correlation coefficient (CC) of 0.95 and normalized root mean square error (NRMSE) of 8.38, indicating excellent performance. The probability of the random variable X falling within the interval [a,b], as described by the probability density function f(x), was calculated using the water demand data. The cumulative distribution function was used to calculate the probability of the random variable being less than or equal to a specific value. These calculations were used to establish the criteria for each stage of the crisis alert system. Decision tree (DT) and random forest (RF) models, based on AI-based classification, were used to predict water demand at the Gurye intake station. The models took into account the impact of water demand from the previous day, as well as the effects of rainfall, maximum temperature, and average temperature. Daily water demand data from the Gurye intake station and the previous day’s rainfall, maximum temperature, and average temperature data from a nearby observatory were collected from 2004 to 2021. The models were trained on data from 2004 to 2015 and validated on data from 2016 to 2021. Model accuracy was evaluated using the F1-score, with the random forest model achieving a score of 0.88, indicating excellent performance.

The Value-Creation Role Of Accessibility Through the Critical Realism Method: Istanbul Bus Rapid Transit System
Authors: ÜNVER GÖÇER Ümit Özlem
Published: November 2023

Public investments in "mass transit systems" provide an equal right of accessibility economic and social opportunities for everyone. Concurrently, they generate an increase in land value both along the mass transit line and within the accessible area of the stations. This article focuses on the socio-economic and spatial effects of the increased land value resulting from the accessibility created by the mass transit system. By reviewing world wide case studies and practices, it examines these causal processes within the framework of the Critical Realism Method using the example of the Istanbul Bus Rapid Transit (BRT) System. As a result of the Extensive Analysis, an analytical method of the Critical Realism Method, it was observed that the rate of land value increase in the Istanbul BRT System was 28% and the rate of land value increase at all stations along the line varied between 20% and 280%. In the Intensive Analysis, it was observed that the increase in land value at selected stations varied depending on the proximity of the station to Istanbul's Central Business District, new incoming land use types, plan changes made by the public, the presence of vacant lands that would enable land speculation, and the presence of large projects around the station. This article provides insights which explains that “the change in land value resulting from accessibility” does not cause the same magnitude of value increase at every station along the line and does not create the same socio-economic and spatial impact at every station. It presents an empirically tested study by comparing the accessibility created by the Istanbul BRT System before and after its implementation.
A STUDY OF THE INFLUENCE OF BRAND IMAGE ON THE PURCHASE INTENTION OF NEW ENERGY VEHICLES: THE MEDIATING EFFECT OF BRAND TRUST AND THE MODERATING EFFECT OF PERCEIVED VALUE
Authors: Zhong Xin Tu
Published: November 2023

This article examines new energy vehicles as the research subject and analyzes the impact mechanism of brand image on purchase intention through empirical research. The research model is constructed based on the Stimulus-Organism-Response theory (S-O-R) and Theory of Planned Behavior (TPB). In this model, brand image is the independent variable, brand trust is the intermediary variable, purchase intention is the dependent variable, and perceived price is the moderating variable. Research hypotheses are proposed. A survey questionnaire is used to gather raw data, hypothesis testing is conducted using SPSS 21, and research conclusions are derived through empirical analysis. The results indicate that brand image significantly and positively affects consumers' purchase intention. Brand trust plays a mediating role in the relationship between brand image and purchase intention. Perceived value moderates the relationship between brand trust and purchase intention. Based on the research findings, specific management practices are proposed to optimize the brand image of new energy vehicles and stimulate and enhance consumers' purchasing intentions. The findings suggest prioritizing the cultivation of a strong brand image to boost purchasing intentions, addressing cognitive biases to strengthen brand trust, and focusing on developing perceived value to stimulate purchasing intentions.

Authors: Chu Hongwei , Guo Hui
Published: November 2023

This study establishes a comprehensive framework where employee innovation behavior serves as the dependent variable, while organizational culture and informal organizational communication act as independent variables, and retention intention functions as the mediating variable. The foundational conceptual framework extends to include demographic variables such as gender, age, and education. Based on this structure, the study presents the following hypotheses: 1. Positive relationship between organizational culture and retention intentions. 2. Positive impact of informal organizational communication on retention intentions. 3. Mediating role of retention intentions in the organizational culture-innovative behavior link. 4. Mediating role of retention intentions in the informal organizational communication-innovative behavior link. 5. Within the context of retention intentions as a mediator, this hypothesis asserts that both organizational culture and informal organizational communication positively affect the innovative behavior of Chinese R&D personnel. The research methodology involved the distribution and retrieval of 500 questionnaires through a stratified sampling approach within the Chinese R&D workforce, encompassing both public and private organizations across the technology, pharmaceutical, automotive, and electronics sectors. The study's findings indicate a robust positive relationship between organizational culture and employees' inclination to remain within the organization. Similarly, a strong positive association exists between informal organizational communication and the willingness of employees to stay. Through an empirical exploration of Chinese R&D personnel across diverse industry domains, this research delves into the intrinsic dimensions of organizational culture, informal organizational communication, retention intentions, and employee innovative behavior. These findings contribute valuable insights to organizations' developmental endeavors.

Были сформированы 6 групп коров третьей лактации по 15 голов в каждой по принципу аналогов аллельных вариантов каппа-казеина. Разница по 3-й лактации между коровами III группы (7060 кг) и остальными группами составила 307, 543, 270, 283 и 112 кг молока соответственно. По содержанию жира и белка в молоке разница составила в пределах 0,01–0,04% по группам. В связи с этим по количеству молочного жира разница была незначительная – в пределах 12,19–21,94 кг. Установлено, что наибольшая вариабельность (Cv%) характерна для удоя, затем величина коэффициента вариации последовательно убывает по массовой доле жира и белка в молоке. Наибольшая изменчивость по удою (15,37%) наблюдалась у коров IV группы. Связь между удоем и содержанием белка в молоке была положительная у животных всех групп (+0,07…+0,52), кроме коров VI группы (k-сas (BB)), у которых она была слабая отрицательная (–0,37). Отрицательная связь массовой доли жира и белка наблюдалась в молоке коров I, II, IV и V групп, а у животных III и VI групп она была положительной, но достоверной только у коров VI группы (Р > 0,95). В молоке коров всех подопытных групп установлена высокая положительная и достоверная связь между массовой долей белка и его основной фракцией – казеином.

Проанализирована скаковая карьера кобыл чистокровной верховой породы, несущих вариант Т/Т полиморфизма гена миостатина. Выявлено, что встречаемость такого типа полиморфизма у отечественного поголовья выше, чем у поголовья в других странах. Результативность испытаний кобыл с типом полиморфизма Т/Т более высока в трёхлетнем возрасте и на дистанциях свыше 1600 м. Из 19 скакавших лошадей побед добивались 7, а призовых мест – 11, но только две кобылы побеждали несколько раз и 6 кобыл имели в карьере несколько призовых мест. В результате проведённого анализа становится понятно, что большинство (более 63%) лошадей, несущих гомозиготный вариант Т/Т, выдерживают многолетнюю ипподромную эксплуатацию с достаточно высокой её результативностью. Возможно также, что импортированные лошади, в силу большего присутствия в родословных кровей фляеров, имеют преимущество на скаковой дорожке, поскольку обладают выраженными резвостными качествами. Как известно, стайер без предрасположенности к резвостным броскам – самая бесперспективная для скакового использования лошадь, так как обладает только выносливостью, без способности делать резвые броски по дистанции и на финише. Скаковой класс кобыл с вариантом полиморфизма Т/Т раскрывается в старшем возрасте и на дистанциях более 2000 м. Так, более значимые совокупные за карьеру призовые суммы (от 150000 до 1760000 рублей) получены при выступлениях в призах на удлинённые дистанции – 2000 и более метров.

The racing career of Thoroughbred mares carrying the T/T variant of the myostatin gene polymorphism was analyzed. It was revealed that the occurrence of this type of polymorphism in domestic livestock is higher than in livestock in other countries. The test performance of mares with the T/T type of polymorphism is higher at the age of three and at distances over 1600 m. Of the 19 horses that raced, 7 achieved victories and 11 won prizes, but only two mares won several times and 6 mares had several winning places in their careers. As a result of the analysis, it becomes clear that the majority (more than 63%) of horses carrying the homozygous T/T variant withstand long-term of racetrack use with fairly high performance. It is also possible that imported horses, due to the greater presence of flyer blood in the pedigrees, have an advantage on the racing track, since they have pronounced agility qualities. As you know, a stayer without a predisposition to make quick throws is the most unpromising horse for racing use, since he only has endurance, without the ability to make quick throws along the distance and at the finish line. The racing class of mares with the T/T polymorphism variant is revealed at an older age and at distances of more than 2000 m. Thus, more significant total prize sums during a career (from 150000 to 1760000 rubles) were received when competing in prizes at extended distances – 2000 meters or more.

Предложен комбинированный агрегат обработки почвы и посева, обеспечивающий оптимальное размещение семян в почве. Важным элементом устройства размещения семян является перфорированная труба. В результате расчётов и пространственного моделирования ранее были выявлены зависимости: количества драже между первым и вторым сбрасывателем от наружного диаметра перфорированной трубы, максимального количества отверстий от наружного диаметра перфорированной трубы, исходя из геометрии перфорированной трубы и возможного количества драже между первым и вторым сбрасывателем. На основании проведённых исследований предварительно определён оптимальный наружный диаметр, количество отверстий в поперечном сечении перфорированной трубы и угол между осями этих отверстий. Ранее путём моделирования и расчётов установлена корреляция скорости агрегата с диаметром перфорированной трубы при безударном попадании драже в отверстие перфорированной трубы. Однако для правильной конструктивной компоновки высевающего устройства следует рассмотреть другие варианты. Поэтому рассчитаны параметры оптимального посева семян при небезударном контакте драже со стенкой отверстия и выведены зависимости параметров от наружного диаметра перфорированной трубы.

A combined tillage and sowing unit has been proposed, which ensures optimal placement of seeds in the soil. An important element of the seed placement device is the slotted pipe. As a result of calculations and spatial modeling, the dependencies were previously identified: the number of dragee between the first and second tripper diverter on the outer diameter of the slotted pipe, the maximum number of holes from the outer diameter of the slotted pipe, based on the geometry of the slotted pipe and the possible number of dragee between the first and second tripper diverter. Based on the research carried out, the optimal outer diameter, the number of holes in the cross-section of the slotted pipe and the angle between the axes of these holes were preliminarily determined. Earlier, by modeling and calculations, a correlation of the speed of the unit with the diameter of the slotted pipe was established in case of non-impact hit of dragee into the hole of the slotted pipe. However, other options should be considered for proper design of the seeding device. Therefore, the parameters of optimal sowing of seeds for non-impact contact of the dragee with the wall of the hole were calculated and the dependences of the parameters on the outer diameter of the slotted pipe were derived.

В статье представлен разработанный авторами фильтр с полимерными элементами, имеющий микроконтроллерную систему, которая управляет выходной частотой ультразвукового генератора и питает блоки многослойных преобразователей. Частота механического резонанса колебательной системы зависит от многих параметров и меняется в процессе работы. Со временем фильтрующие элементы забиваются, теряя эффективность очистки масла. Поэтому фильтрующие элементы заменяются новыми. Для обеспечения высокой эффективности частота очистки фильтра должна постоянно контролироваться и настраиваться на резонансную частоту. Применение микроконтроллерной системы позволит управлять ультразвуковым преобразователем, отправляя пакеты импульсов с частотой 30 кГц, для обратной связи применяется датчик ультразвука HC-SR04. Данный датчик необходим для контроля передачи преобразователем ультразвуковых колебаний. В приведённых расчётах по преобразователю ультразвуковых колебаний резонансная частота будет составлять 35,5 кГц, что соизмеримо с частотой передачи импульсов микроконтроллера.

The article presents the filter with polymer elements developed by the authors, having a microcontroller system that controls the output frequency of the ultrasonic generator and feeds the blocks of sandwich transducers. The frequency of mechanical resonance of the oscillating system depends on many parameters and varies during operation. Over time, the filter elements become clogged, losing the efficiency of oil cleaning. Therefore, the filter elements are replaced with new ones. To ensure high efficiency the filter cleaning frequency must be constantly monitored and tuned to the resonant frequency. The use of a microcontroller system will allow you to control the ultrasonic transducer by sending pulse packets at a frequency of 30 kHz, a HC-SR04 ultrasound sensor is used for feedback. This sensor is necessary to monitor the transmission of ultrasonic vibrations by the transducer. In the calculations given by the ultrasonic oscillation transducer, the resonance frequency will be 35.5 kHz, which is commensurate with the pulse transmission frequency of the microcontroller.

Authors: Mahliati
Published: November 2023

This research explores the role of the community in fostering moral education for children in Batee Shok, Sabang City, Indonesia, and identifies the challenges hindering optimal moral development. The study investigates the educational landscape, considering factors such as community collaboration, moral education practices, available resources, mentorship, and the societal environment. The findings highlight that the community's efforts in Batee Shok are not fully optimized for effective moral education. While advice is provided to children, there is a notable absence of setting good examples and engaging in essential Islamic activities. The study identifies several obstacles, including the lack of community attention and collaboration, insufficient moral education within the community, limited resources for Islamic educational activities, scarcity of qualified mentors, and an unfavorable societal environment. To address these challenges, the research recommends increased community involvement, setting positive examples, and active engagement in moral education initiatives. Additionally, local leaders and influential figures are encouraged to play a more active role in shaping the moral landscape for children in Batee Shok. Furthermore, collaboration with governmental institutions is suggested to enhance resources and support for Islamic educational activities. These recommendations aim to improve the quality and effectiveness of moral education programs for children in Batee Shok.
The Concept of Forming Shaleh Children According to Islamic Education
Authors: Risnawaty Rattry
Published: November 2023

Children, viewed as a divine trust from Allah SWT, are entrusted to parents from the moment they grace the world. This bequeathed responsibility mandates parents to meticulously nurture and educate their progeny, directing them towards the cultivation of utility and noble character. Born in a state of fitrah, children's trajectories, whether towards virtue or peril, hinge significantly upon the guidance provided by parents. This responsibility extends beyond mere guidance; parents are entrusted with the monumental task of instilling piety in their children—a duty often underestimated by a substantial number of parents, despite explicit guidance in the Al-Qur'an and Hadith regarding the pivotal role of righteous offspring. This research, titled Concept of Forming Pious (Shaleh) Children According to Education, delves into this critical matter with precision. The research objectives encompass a nuanced understanding of the principles underpinning the cultivation of piety in children through education, exploration of methodologies employed in educating pious children, and identification of strategic efforts to foster piety from an educational standpoint. Employing a descriptive research methodology, the study undertakes a comprehensive examination of current issues through a thorough library research approach. The findings of this research underscore the imperative of cultivating pious children with the aim of nurturing individuals of noble character, thereby contributing to peace and tranquility in both temporal and spiritual realms. The practice of educating children in piety is characterized by its enduring nature, persisting beyond the corporeal realm, as the prayers of pious children become a poignant means of salvation for parents from the fires of hell upon their demise. The conceptualization of forming a pious child according to education involves the developmental nurturing of their soul, even within the confines of the womb, with the overarching goal of achieving virtuous outcomes. Efforts to foster pious children, from an educational perspective, entail the deliberate incorporation of moral education in both formal and informal educational settings. The methodologies employed in shaping pious children through education encompass exemplariness, adherence to cultural norms, the provision of advice, focused attention, and judicious application of appropriate disciplinary measures. In consideration of these insights, this research anticipates active parental engagement in cultivating their children's moral compass, fostering the nuanced development of pious offspring. Encouraging community participation in shaping the moral character of children towards piety is deemed essential. Furthermore, the sustained and active involvement of educators in schools, dedicated to imparting moral values, is paramount for the realization of a society characterized by pious children.

Natural resources (SDA) are wealth that not every country in the world has. Natural Resources are divided into several parts according to their classification, including Mineral Resources. Mineral Resources are natural resources that contain minerals and mining materials that have economic value. The materials contained therein are usually used as high-value production materials, this is what causes mineral resources to sometimes be used inefficiently. One of the mineral resources in Indonesia is in Central Java Province, precisely in the city of Semarang, which is commonly known as "Brown Canyon". The "Brown Canyon" area is rich in natural mineral resources which are ultimately used by the community as work land in the form of mining, on the other hand, "Brown Canyon" is also used as a natural tourist attraction. The mineral content in the form of sand and stone in this area has a promising economic value for the surrounding community, but behind this economic value the existing content or reserves are not yet fully known. In this research the author will analyze the current conditions of the "Brown Canyon" area, especially in terms of the availability of mineral resources in the area using qualitative and survey methods. The results of the calculation of mineral reserves were obtained at 1,918,800 tons. Mineral reserves in the form of stone and sand in Brown Canyon will be exhausted within 17 years with annual mineral resource extraction of 108,000 tons.

The existence of waste in tourist areas does not only have a negative impact locally but also globally. The process of decomposing organic waste produces greenhouse gases, while plastic inorganic waste which is difficult to decompose causes higher levels of microplastic pollution in the environment. The purpose of this study is to analyze waste generation and to utilize organic waste produced in the Air Salobar Culinary Tourism area to become eco enzyme. This research was conducted in March-June 2023 in the Air Salobar Culinary Tourism area, Nusaniwe District, Ambon City. Retrieval and analysis of inorganic waste data refers to SNI 19-3964-1994. The classification of inorganic waste is based on the classification of marine debris according to UNEP (United Nations Environment Programme). Collection of organic waste and processing it into eco enzyme using the observation method. The resulting data is then displayed in the form of tables, diagrams and figures for further discussion. The results of the study proved that the total weight of waste generated in this tourist area was 215.91 kg consisting of 213.37 kg of organic waste and 2.54 kg of inorganic waste. The weight of waste generation both organic and inorganic waste generated during 10 days of observation was 0.22 kg/person/day with a volume of waste generation of 0.84 liter/person/day. The potential for recycling inorganic waste is 99% of the total weight of inorganic waste produced. The potential for recycling organic waste into eco enzyme is 73.16 kg or 80% of the weight of the fruit peel organic waste produced. The eco enzyme solution obtained after 3 months of fermentation is 6.2 liter. The results of this study indicate that the waste generated in the Air Salobar Culinary Tourism area can be recycled which is beneficial both ecologically and economically.

Soil dust is the most difficult object of research to find in applications, even though it is rich in silica, silicate, and aluminosilicate compounds, which are widely known as adsorbents. The physical and chemical characteristics of compounds in which the main framework is the oxides of silicon and aluminum in the material are usually related to their Si/Al mole ratio. This study aims to study the effect of changes in the levels of silicon, aluminum, and related elements in alkaline or acid-treated soil dust (DTBA) in adsorbing methylene blue (MB). The difference in the composition of the elements in DTBA is expressed in terms of the mole ratios of silicon to aluminum, (Si/Al)mole, the ratio of moles of silicon to the number of moles of aluminum and iron, (Si/(Al+Fe))mole, the ratio of moles of silicon to the number of moles of aluminum, iron, and calcium, (Si/(Al+Fe+Ca))mole, and the mole difference of silicon to aluminum, (Si-Al)mole. The quantities in moles were also tested using the levels of these elements: (Si/Al)weight, (Si/(Al+Fe))weight, (Si/(Al+Fe+Ca)weight, and (Si–Al)weight. Through linear and non-linear regression (2nd order polynomial), plotting of the concentration of adsorbed MB to (Si–Al)weight had the highest correlation coefficient (R2 = 0.9767), better than (Si/Al)mole (polynomial 2, R2 = 0.5177), (Si/(Al+Fe))mole (polynomial 2, R2 = 0.7940), and (Si/(Al+Fe+Ca))mole (linear, R2 = 0.7996) or the same based on percentage of weight, (Si/Al)weight (polynomial 2, R2 = 0.9105), (Si/(Al+Fe))weight (polynomial 2, R2 = 0.6649), and (Si/(Al+Fe+Ca))weight = (polynomial 2, R2 = 0.5601). From a number of optimizations, the adsorption of MB on DTBA was close to the Langmuir and Redlich-Peterson isotherm adsorption model, which describes that there was one layer of MB adsorbate on the surface of DTBA. With this result, soil dust resulting from alkaline or acid treatment can adsorb MB on its surface, which is determined most by the difference in the weight of silicon to aluminum.

Rizikos visuomenėje iškyla klimato kaitos, biologinės įvairovės nykimo, ekocido, aplinkos apsaugos klau­simai. Ekologinis diskursas fokusuojamas į žmogaus atsakomybės, technologinės rizikos valdymą, darnią raidą, žmogaus poreikių tenkinimą ir gamtos išsaugojimą. Šiame straipsnyje, remiantis aplinkosaugos požiūriais ir rizikos visuomenės teorija tiriamas ekosąmoningumo suvokimas šiandieninėje visuomenėje. Tiriamieji LSMU bakalauro studijų studentai, dalyvavę paskaitose apie ri­zikos suvokimą ir komunikaciją, ekologinę antropologiją, aplinkos sveikatą ir sutikę dalyvauti focus grupės tyrime. Tiriamasis laikotarpis 2019-2023 metai.

Tyrimas atskleidžia skirtingas aplinkosaugines pažiūras ir augantį studentų ekologinį nerimą. Tyrimo dalyviai suvokia rizikas gamtai kaip prioritetines, o aplinkosau­gos problemų keliamą riziką žmogaus sveikatai sieja su žala visai ekosistemai, tuo pritardami ekocentristiniam požiūriui. Tiriamieji teigia, kad antropocentristinės pa­žiūros dominuoja visuomenėje, nes žmogaus poreikiai iškeliami aukščiau gamtos. Tyrimo duomenys rodo, kad aplinkos apsauga dėl žmogaus sveikatos ir gerovės pa­tvirtina sekliosios ekologijos poziciją.

Vakarų visuomenėje vyrams skirtų veido odos priežiū­ros produktų rinkos plėtojimas yra svarbus poslinkis, siekiant didesnio vyrų dėmesio kūno gražinimui, veido odos puoselėjimui, akcentuojant „sėkmingo senėjimo“ idėją. Kintant vyrų odos priežiūros įpročiams, didėja vy­rams skirtų kosmetikos priemonių vartojimas ir poreikis, tačiau vyrų kosmetikos rinka vis dar nėra pakankamai išvystyta. Skutimasis daugeliui vyrų buvo ir tebėra vie­nintelė kasdienė veido odos priežiūros procedūra, o senė­jimą stabdančioms kosmetikos priemonėms nuo raukšlių dėmesys nėra pakankamas.

Darbo tikslas − įvertinti vyrų veido odos kosmetologinės priežiūros įpročius ir motyvaciją lemiančius veiksnius.

Metodika. Atliktas kiekybinis tyrimas: anoniminė inter­netinė apklausa. Apklausoje dalyvavo Klaipėdos apskri­tyje gyvenantys 354 vyrai, nuo 18 iki 65 metų, amžiaus vidurkis – 26,66±8,77 metų. Tiriamuosius motyvuojan­tys veiksniai vertinti 5 balų Likerto skalėje. Nustatytas klausimų patikimumas: Cronbach alfa koeficientas lygus 0,7. Statistinė duomenų analizė atlikta naudojant SPSS 26 programinį paketą. Taikytas Kolmogorov-Smirnov, Mann-Whitney U, Kruskal-Wallis H testai, Spearman koreliacijos koeficientas. Skirtumai tarp lyginamų grupių ar požymių laikyti statistiškai reikšmingais, kai p≤0,05.

Išvados. Daugiau nei pusė apklausoje dalyvavusių Klai­pėdos apskrities vyrų naudoja veido odos kosmetines priežiūros priemones, dažniau − vyresnio amžiaus as­menys. Ženkliai mažesnė tiriamųjų dalis naudojasi pro­fesionalių kosmetologių atliekamomis veido priežiūros procedūromis grožio salonuose. Jaunesnio amžiaus vyrų, gyvenančių miestuose, tarp veido odos priežiūros mo­tyvaciją lemiančių veiksnių dominuoja siekis išvengti odos estetinių problemų ir būti patraukliu. Auganti vyrų odos priežiūros priemonių rinka rodo didėjantį vyrų su­sidomėjimą veido odos ir viso kūno senėjimo proble­momis ir sveikos jaunatviškos išvaizdos išsaugojimu. Odos priežiūra turėtų būti suprantama kaip bendrosios sveikatos dalis. Holistinis rūpinimasis savo sveikata, ša­linant senėjimo veiksnius, teikia vilties, kad ateities vyrų kartos odos priežiūrą laikys ne tik grožio, bet ir sveikatos stiprinimo priemone.

Straipsnyje siekiama atskleisti bendruomenės slaugytojųbendravimo iššūkius, patiriamus su demencija sergan­čiais pacientais. Tyrimo empirinįpagrindąsudaro12 pu­siau struktūrizuotų interviu su bendruomenės slaugyto­jomis, vizituojančiomis demencija sergančius pacientus namuose. Tyrimo imtis sudaryta patogiosios atrankos būdu, tiriamųjųvidutinis amžius – 37 m., darbo stažas nuo 3 iki 25 metų. Tyrimo duomenųapdorojimui pasi­rinktas kokybinės turinio analizės metodas.

Tyrimo metu nustatyta, kad bendruomenės slaugytojo patiriami bendravimo su demencija sergančiu pacientu iššūkiai susiję su paciento būkle, aplinkos ir slaugytojų veiklos charakteristikomis. Sudėtingiausi bendravimo iššūkiai susiję su sergančiųjų demencija kognityvinių funkcijų sutrikimais, psichologine paciento būkle ir emo­cinėmis reakcijomis. Silpnėjantis mąstymas, atmintis, orientacija, suvokimas, kalbos sutrikimas tiesiogiai veikia paciento ir slaugytojo bendravimo kokybę − slaugytojams sunku suprasti pacientą, o stiprėjant demencijos požy­miams, didėja ir grįžtamojo ryšio sutrikimai, komunika­cija įgauna vienkryptę eigą. Slaugytojai susiduria su pa­cientų neverbalinės kalbos atpažinimo ir interpretavimo problema. Tyrimas atskleidė, jog demencijos požymiams tampant pastebimiems, pacientai susiduria su stigmati­zuojančiais požiūriais visuomenėje, jie laikomi kitokiais ir neretai išstumiami iš socialinių vaidmenų ir veiklų, gilėja saviizoliacija. Tyrimas atkleidė, jog bendravimui įtakos turi tokios fizinės aplinkos charakteristikos, kaip triukšminga aplinka ir patalpos apšvietimas, saugios ir komfortiškos aplinkos, kaip ją subjektyviai suvokia pa­cientas, pasirinkimas. Artimojoje aplinkoje, slaugytojams bendravimo iššūkius kelia artimųjų nenoras bendrauti, žinių stoka, nepasitikėjimas bendruomenės slaugytoju, demencijos diagnozės neigimas, neretai pasireiškiančios depresyvios artimųjų būsenos, nerimas ir netgi agresija. Tyrimas išryškino, jog bendruomenės slaugytojų komu­nikacijos kokybė priklauso nuo darbo patirties, nes per ilgesnę darbo patirtį susiformuoja praktikos patvirtinti elgesio ir bendravimo su demencija sergančiu pacientu modeliai. Bendravimo iššūkiai susiję ir su žinių stoka, verbalinės ir ypač neverbalinės komunikacijos indivi­dualizavimu, priklausomai nuo paciento poreikių ir si­tuacijos. Slaugytojų darbo organizavimo aspektai, tokie kaip laiko trūkumas ir didelė slaugytojų kaita, neigiamai veikia bendravimą.
