Pemulihan merupakan satu bentuk perkhidmatan sosial bagi memulihkan individu yang menghadapi masalah tingkah laku negatif. Pemulihan holistik adalah konsep pemulihan yang memperluas dan memperdalam proses tersebut. Hal ini tidak hanya membantu dalam mempromosikan sikap positif terhadap proses pemulihan, tetapi juga mengembangkan keterampilan sosial yang diperlukan untuk menghadapi dunia moden. Selain itu, pemulihan holistik juga harus mempertimbangkan tentang perubahan dan tantangan sosial budaya. Kajian bertujuan membangunkan model pemulihan holistik terhadap kumpulan LGBT. Kajian ini penting bagi menyumbang kepada usaha-usaha pemulihan LGBT oleh pihak kerajaan mahupun bukan kerajaan. Pemulihan holistik dan komprehensif perlu dibangunkan iaitu pemulihan spiritual dan jasmani secara bersepadu. Kumpulan LGBT merupakan komuniti yang perlu dibantu dalam proses pemulihan. Justeru, model pemulihan holistik terhadap kumpulan LGBT perlu dibangunkan untuk membantu individu yang terlibat dalam gejala songsang ini kembali hidup mengikut cara hidup Islam dan kembali. Dalam mengimplementasikan kajian ini, teknik Fuzzy Delphi (FDM) telah digunakan. Dalam konteks ini sebuah model pemulihan holistik yang memfokuskan kepada elemen pemulihan yang menyeluruh dan komprehensif iaitu pemulihan spiritual dan jasmani secara bersepadu terhadap kumpulan lesbian, gay, biseksual dan transgender (LGBT). Hasil kajian ini mendapati terdapat empat item utama membentuk model pemulihan yang dibangunakan iaitu kerajaan, badan bukan kerajaan, komuniti masyarakat dan komuniti LGBT.

Published: January 2024

International peacekeeping mission is an important mechanism in the aspect of contemporary international conflict management. Since its first implementation by United Nations (UN) wayback in 1948, it attracted interest and participation from many countries in the organization. This includes the Islamic countries. Since the end of the Cold War era in the late 1980s, Islamic countries emerged as among the leading participant and troop contributor to international peacekeeping mission especially the mission organized by the UN. Half of the top-ten troop contributors to the current UN mission today are the Islamic countries such as Bangladesh, Pakistan, Egypt, Indonesia and Ghana. Even though Islamic countries had been contributing actively in numerous UN missions, nothing much were known about it. This article discussed in brief about the scenario of Islamic countries participation in international peacekeeping mission by referring to the mission organized by the UN and non-UN organizations since its early years to the present time. The approach use in this article are historical analysis and content analysis. This article concluded that, firstly, this scenario served as an evidence of Islamic countries un-ending support to the UN as a world governing body; secondly, national interest and not religious interest seems to be the primary driving factor of Islamic countries participation in peacekeeping; and finally, while Islamic countries continued its active participation in this areas of contribution, it nevertheless had to familiarize itself with the impacts and challenges that it currently faced which maybe will limited its noble effort to continue its support to international peacekeeping mission in the near future.

Authors: Hashim Nur Iman , Mohd Fauzi Nadzirah
Published: January 2024

Over the last decade, there has been a growing emphasis on the creation of Islamic-related products and services. In response to this trend, hotels developed novel offerings for Muslim customers known as Muslim-Friendly Hotels. However, there has been a paucity of study on the features and implementation of Muslim-Friendly Hotels in the hotel business. As a result, the goal of this study is to better understand the practise of Muslim-Friendly Hotels in Malaysia. A focus group discussion was conducted in this preliminary study to get a knowledge of the practise and issues connected with using the MFH concept in hotel operations in Malaysia. In total, six panels were part in the discussion. The debate was recorded, and the dialogue, as well as the remarks made throughout the discussion, were transcribed, and then categorised based on the questions raised during the discussion. In general, this research discovered three issues in implementing Muslim-Friendly Hotels in Malaysia, including the uncertainty of government regulation, the lengthy procedure of obtaining the Halal certificate, and the lack of a solid supporting system to support the implementation of Muslim-Friendly Hotels. In addition, two Malaysian Standards, MS1900:2005 and MS2610:2015, have been recognised and strongly recommended for incorporation as a unified system in implementing the Muslim-Friendly Hotel idea.

The Problem of Islamic Philosophy: Definitions and Origins
Authors: Ismail Khalid , Wan Halim Wan Mohd Amjad , Yahya Zikri Soliha
Published: January 2024

Islamic philosophy is the product of a complex intellectual process in which Syrians, Arabs, Persians, Turks, Berbers and others took an active part. When we speak of Islamic philosophy we mean that a philosophy which development, and modalities, are essentially linked to the religions and spiritual fact of Islam. Sometimes the researchers of Islamic philosophy had also used the term Arabic Philosophy or Muslim Philosophy rather than Islamic. Islamic philosophy presents us with a number of unresolved questions having to do with its origin and its relation to Greek philosophy. However, the term Islamic philosophy preferable to the others. For example, in Islam, it has been explained in how Islamic philosophy was internally taken by the thought of the Quran through its propagation within the first Muslim community. It must also be included in the notion of the Quranic concept 'Sunatullah' or 'natural' which means the characteristic or trait given by God ‘alluding thereby to nature as something that is created by God It should not deny the importance of the science of metaphysics because it is very close to our reality. This study attempts to elaborate the development of Islamic philosophical ideas and analyses them from the Islamic theologico-philosphical views. This study examined the terms of the Islamic philosophy, analyze the function and structure of the terminology mentioned in the Qur'an since Allah's Commandments would have explicit and implicit wisdoms. This study is a qualitative study using content analysis method, as the subject determination. The results shown the terms which are issued in history of Islamic thought from various classical schools of Islamic thought which is Islamic philosophy will be defined it with regard to its fundamental characteristics mainly in connection to its origin.

El retorno a la presencialidad ha hecho sonar las alarmas del sedentarismo construido durante el confinamiento debido a la tendencia por la comodidad de no salir del nido. Este ensayo delibera la derivación que ha tenido la pandemia del COVID-19 en las instancias educativas en el sur del Perú. Tras una breve introducción, se aborda el miedo al cara a cara de los principales actores que dinamizan el corpus educacional y el desarrollo específico de la educación en los Andes. Como ramificación del constructo teórico, existe en las personas estudiantes la añoranza hacia el pasado invernal sacudido por las ondas vibratorias del murciélago de Wuhan, porque, con el retorno a la presencialidad, sus comodidades en la red de internet y la excusa de estar en clases virtuales para no ocuparse de ciertas responsabilidades académicas y domésticas, ya no serán posibles. En cuanto a la esfera magisterial, se reanuda el combate frontal hacia los múltiples problemas educativos en el país, abandonado por dos largos años; finalmente, para el estrato de progenitores, se aparece en el túnel de la preocupación, la luz de esperanza de ver a sus hijos(as) nuevamente con el sagrado uniforme escolar.

La voz de la infancia en el pasado: fundamentos para una enseñanza renovada de la historia y su posible consideración en el currículum chileno
Authors: Álvarez Sepúlveda Humberto Andrés
Published: January 2024

El currículum chileno de Historia y los textos escolares de esta asignatura se caracterizan por fundarse en un relato adultocéntrico que excluye la participación de la niñez en el estudio del pasado, ya que se han focalizado en describir las proezas políticas, económicas y militares lideradas por hombres adultos pertenecientes a los sectores dirigentes. En función de esta problemática, este ensayo plantea una reflexión filosófico-educativa que tiene por objeto fundamentar la necesidad de resignificar el rol histórico de los niños para deconstruir el tratamiento de estos como agentes desterrados de la historia escolar o como sujetos subalternos del mundo adulto. Desde un punto de vista metodológico, este ensayo se apoya en la revisión documental de diferentes textos alojados en bases de datos como Scielo, Clacso, Redalyc, Wos, Scopus, ProQuest, Latindex y Dialnet, de las cuales se escogieron trabajos procedentes fundamentalmente de Chile, México y España, que examinaran la importancia de repensar el tratamiento de los niños y niñas presente en el currículum chileno de Historia, especialmente en los manuales de la especialidad. Esta búsqueda se llevó a cabo a partir de las siguientes palabras clave: Chile, historia escolar, infancia, currículum nacional, textos escolares, adultocentrismo, didáctica de la historia y pensamiento histórico. Se recurrió al método argumentativo para sustentar teóricamente la reflexión consignada. Como conclusión, se señala que resulta fundamental adoptar la perspectiva infantil en la historia, ya que ayuda a los niños a formarse como personas ciudadanas críticas y conscientes de sus derechos y deberes.

The price of chemical fertilizers and potential environmental risks are the reasons for using compost. Liquid compost extracted from compost has many advantages that a compost. Liquid compost is available quickly and has a higher concentration compared to compost. The effectiveness of liquid compost depends on the aeration treated in the production process. The study aimed to determine the growth of corn plants fed with either aerated liquid compost or an aerated liquid compost. This study was conducted by a Complete Randomized Design with two factors. The first factor is the type of liquid compost, aerobic and anaerobic liquid compost. The second factor is the dose of a liquid compost, 100 ml and 200 ml of liquid compost. The growth medium was drenched with aerobic or anaerobic liquid compost in the first and third weeks after planting. The results showed that plants fertilized by aerobic or anaerobic liquid compost increased plant growth. The plant fertilized by anaerobic liquid compost had higher plant growth than it fertilized by aerobic liquid compost.

Published: January 2024

This paper studies the optimal ratio that gives the highest caffeine amount and improves the efficiency and quality of extraction from Arabica Gayo coffee beans. No previous studies have explored the best ratio of Gayo Arabica coffee beans to ethyl acetate solvent for extracting caffeine. The paper explains the method used, which has four main steps: preparing materials, extracting and measuring caffeine, and analyzing the results. The paper presents the experimental findings and discusses how different ratios affect caffeine content in Arabica Gayo coffee beans. It uses statistics to show significant differences between the ratios and compares them using Tukey tests. The paper concludes that the best solvent-to-coffee ratio for maximizing caffeine in ethyl acetate extracts is 1:5, resulting in a concentration of 1411.1 ppm. This ratio gives the best balance between caffeine yield and solvent usage.

Monsoon-driven switch of heavy to light copper isotopes in suspended particulate matter in the Changjiang (Yangtze River)
Authors: Vasquez Ana , Shouye Yang , Zhiwei He , Junjie Guo
Published: January 2024

The East Asian monsoon system is generated by land-ocean thermal
contrast between Asia and NW Pacific, altering the hydroclimate
variability in the region. Suspended particulate matter (SPM) consists
of a mixture of geochemical pools with distinct origins, evolutionary
paths, behaviors and isotopic signatures. The characteristics of SPM
reflect the physical processes occurring within a river catchment,
including erosion, sediment transport, nutrient and pollutant movement,
and organic matter dynamics. The Changjiang is the second largest
supplier of global SPM, discharges the largest fresh water and suspended
sediment discharge into the East China Sea, significantly influencing
the oceanic mass balance. The Changjiang basin is subject to the Indian
Monsoon in its headwaters and the East Asian Monsoon downstream, which
dominates the chemical weathering patterns in the basin.

A widespread inherited feature of the Changjiang basin is its heavy Cu
signatures in dissolved and particulate loads. However, the SPM samples
conversely displays light 𝛿Cu values in Lower
Reaches, ranging from −0.26 to +0.45 ‰ (2SD, n=31), with almost constant
Cu concentrations (average ~49
µg/g). Heavy and light Cu isotopic signatures are naturally sourced,
albeit with considerable fluctuations in daily samples. The flood event
in July 2020 elucidate the effect of intense erosion over Cu
concentrations and isotopes, showing larger variations from −0.10 to
+0.45 ‰ (2SD, n=10). We infer that the temporal and spatial variations
in Cu isotopes of Changjiang SPMs with low enrichment metrics is the
combined effects of monsoon-driven weathering and soil erosion in the
large catchment. This study provides new insights into Cu geochemical
behavior during earth surface processes, which will contribute to a
holistic understanding of the global Cu cycle.
Using Kgen to Generate Cross-Verified Apparent Equilibrium Constants (K∗) for Seawater Carbonate Chemistry
Authors: Whiteford Ross , Branson Oscar , Mayk Dennis
Published: January 2024

The state of acid-base equilibria in solutions is calculated using
apparent equilibrium constants (K∗ ’s). The accuracy of these K∗ ’s is
critical for calculations of environmental chemistry, for example the
dissociation of dissolved CO2 in seawater. The K∗ ’s required to
calculate seawater carbonate chemistry are described by empirically
determined functions, which are implemented within software packages
used to calculate solution carbon speciation. Each of these software
packages uses its own implementation of these K∗ calculations. This
fragmented approach to K∗ calculation results in unintended and
difficult to resolve discrepancies between outputs calculated by
different pieces of software, particularly because of the empirical
nature of the K∗ functions which are subject to revisions and
improvements over time. We present ‘Kgen’, a collection of software to
consistently calculate seawater K∗ ’s in Python, R, and Matlab. Kgen
provides a nearly identical interface for each language and, through use
of a Continuous Integration/Continuous Delivery (CI/CD) pipeline,
guarantees consistency between languages by automatically cross-checking
results from all three implementations. Unifying the approach to K∗
calculation in this way provides an extensible platform for verifiable
K∗ generation, which can be easily integrated into existing carbon
speciation calculators to improve consistency of results.
Systems Engineering Transformation: Transdisciplinary Endeavor
Authors: Ford LynnDee , Ertas Atila
Published: January 2024

System Engineering (SE) solves the most complex problems by bringing together societal issues, theoretical engineering, and the transformation of theory into products and services to better mankind and reduce suffering. The research of this paper utilizes transdisciplinary engineering to develop a SE methodology for the concept stage permitting proposal generation accuracy and expediency to provide solutions to counter regional aggressive threats.

Today’s world stage is witnessing superpower dominance over neighboring less military-capable nations. The societal impact goes beyond the borders of conflict and affects the world’s global market. In the deterrence of dominance, the United States’ posture is providing weapon systems to the victim in our increasingly unstable geopolitical environment. The US has many reasons to make this technology available to other nations; just as it has many reasons to constrain proliferation.

The United States Government is energizing the U.S. defense industry to provide the needed weapon systems following US prescribed acquisition methods. The sale of US weapon systems to International Customers is through a US defense contractor implementing a specialized acquisition model specific for international customers acquiring exportable defense articles. These constraints in the form of export regulations, critical to this paper, are essential to account for early in the concept development. The added complexity to concept development in international defense is that in addition to the usual, “what capabilities does the customer need to accomplish their mission?” and “what are the alternative solutions?” questions, we need to address the fact that US contracts may be required to limit capabilities and/or the technical solution space in opposition to the international customer’s desires. Whereas we normally turn to systems engineering processes to address such complex problems, we have found that the current SE methodology for the concept stage does not address the complexities associated with international sales.

The international customers’ need for complex solutions in an expedited time frame emphasizes the prime contractor’s complex and inadequate proposal concept stage. Under U.S. government procurement, the prime contractor shifts a portion of the design phase into the concept phase. This modality requires significant time and funding to fully develop the technical baseline, meanwhile, the international customer requires a solution to react to an immediate threat to their country’s safety.  The main objective of this research is to develop a system engineering methodology for the concept stage to effectively understand the technical baseline maturity for proposals specific to International Customers.

Authors: Fu Tian , Sun Yuhao , Lu Shiyuan , Zhao Jianhui , Dan Lintao , Shi Wenming , Chen Jie , Chen Yan , Li Xue
Published: January 2024

OBJECTIVE

We aimed to evaluate whether individuals with type 2 diabetes (T2D) were at higher risk of developing a wide range of gastrointestinal diseases based on a population-based cohort study.

RESEARCH DESIGN AND METHODS

This study included 374,125 participants free of gastrointestinal disorders at baseline; of them, 19,719 (5.27%) with T2D were followed-up by linking to multiple medical records to record gastrointestinal disease diagnoses. Multivariable Cox models were used to estimate the hazard ratios (HRs) and CIs. Logistic models were used to examine the associations between polygenic risk scores (PRS) and clinical gastrointestinal phenotypes.

RESULTS

During a median follow-up of 12.0 years, we observed the new onset of 15 gastrointestinal diseases. Compared with nondiabetes, participants with T2D had an increased risk of gastritis and duodenitis (HR 1.58, 95% CI 1.51–1.65), peptic ulcer (HR 1.56, 95% CI 1.43–1.71), diverticular disease (HR 1.19, 95% CI 1.14–1.24), pancreatitis (HR 1.45, 95% CI 1.24–1.71), nonalcoholic fatty liver disease (HR 2.46, 95% CI 2.25–2.69), liver cirrhosis (HR 2.92, 95% CI 2.58–3.30), biliary disease (HR 1.18, 95% CI 1.10–1.26), gastrointestinal tract cancers (HR 1.28, 95% CI 1.17–1.40), and hepatobiliary and pancreatic cancer (HR 2.32, 95% CI 2.01–2.67). Positive associations of PRS of T2D with gastritis, duodenitis, and nonalcoholic fatty liver disease were also observed.

CONCLUSIONS

In this large cohort study, we found that T2D was associated with increased risks of a wide range of gastrointestinal outcomes. We suggest the importance of early detection and prevention of gastrointestinal disorders among patients with T2D.

világ legütőképesebb harckocsijai 1. rész
Authors: Farkas Zoltán
Published: January 2024

A harckocsik a szárazföldi erők legfontosabb harceszközei közé tartoznak. Kiemelt szerepet játszanak a harc megvívásában, bár meghatározó jellegüket egyes szakértők napjainkban már megkérdőjelezik. Az idők során a tervezők folyamatosan tökéletesítették a harckocsit, amelynek az alkalmazók által támasztott követelménynek meg kellett felelniük. A harctéri alkalmazás során szerzett tapasztalatok tehát alapvetően határozzák meg a fejlesztések irányát, így a változtatások-finomítások szinte folyamatosak. Részben ez az oka annak, hogy az egyes típusok különböző változataival egyidőben lehet találkozni. A valós adatokhoz történő hozzáférés nem minden esetben biztosított, ezért a 11 legkorszerűbb típus bemutatása után a szerző nem állít fel sorrendet a harckocsik között. Az ismertetett típusok egymástól eltérő, egy-egy területen kiemelkedő adottságokkal rendelkeznek, de összességében – képességek tekintetében – közel azonos harcértéket képviselnek.

The land-conversion of rice fields can reduce rice production and negatively impact food security. Consequently, monitoring is essential to prevent the loss of productive agricultural land. This study uses a combination of Sentinel-2 MSI, Sentinel-1 SAR, along with SRTM (elevation and slope data) to monitor rice fields land-conversion. NDVI, NDBI and NDWI indices are transformed from the annual median composite Sentinel-2 MSI images used to identify different rice fields with another object. A monthly median composite of SAR images from Sentinel-1 data are used to identify cropping patterns of rice fields in the inundation phase. The classification is performed by using the Random Forest machine learning algorithm in the Google Earth Engine (GEE) platform. Random Forest classification is run using 1000 trees, with a 70:30 ratio of training and testing data from sample features extracted by visual interpretation of high resolution Google Earth imagery. In this study, Random Forest classification is effective in computing a high amount of multi-temporal and multi-sensory data to map rice-field land conversion with an accuracy rate of 96.16% (2021) and 95.95% (2017) for mapping paddy fields. From the multitemporal rice field maps in 2017—2021, a conversion of 826.66 hectares of rice-fields to non-rice fields was identified. Based on the spatial distribution, the conversion from rice-field to non-rice field is higher at the area near the roads, built area and Yogyakarta International Airport. Therefore, it is important to assess and ensure that National Strategic Projects are managed with due regard to environmental impacts and food security.

Published: January 2024

The phenomenon of urban population growth is a global concern which will result in a decrease in the value of ecosystem services in an area. Sukoharjo Regency is an area affected by the development of Surakarta City; therefore, rapid growth is taking place. The objective of this study is to investigate the interplay between urbanization, ecosystem services, and the provision of clean water in Sukoharjo Regency in 2022. The methods used in the study were calculating the percentage of the urban population to determine the level of urbanisation, AHP and overlay to ascertain the ecosystem service score, together with cross-tabulation to establish the relationship between these two variables. The result of this study is that the level of urbanisation produces a pattern that districts in the north tend to comprise a higher level. The clean water supply ecosystem services in Sukoharjo Regency obtained results dominated by the low to medium level. The situation regarding the level of urbanisation and ecosystem services in Sukoharjo Regency reveals a relationship where an increase in the level of urbanisation will reduce the value of ecosystem services.

Published: January 2024

Over the years, electricity has developed into a crucial commodity for any nation. The need to evaluate the rate of electricity consumption in regard to utility management and the spatial distribution of major devices to facilitate appropriate planning within the estate is the motivation for this research. This study used geospatial technology to evaluate the electricity distribution to support planning and management in Omole Estate (Phase One) and environs within the city of Lagos, Nigeria. The focus was on determining the land use in study area, geolocations of the transformers, along with the cost of energy consumed per household. Spatial data for the research area was collected through a Hand-held GPS. Google Earth images were downloaded to supplement the data, and a comprehensive analysis of administered and recovered questionnaires was conducted to enrich the dataset. ArcGIS 10.6.1 software was employed to create the database and depict the area, whilst modifying all of the details required within. The result confirms that 72% of the respondents use electricity for domestic use, 18% for commercial use while 10% utilise it for domestic and commercial use. A significant portion of homes (33%) still use outdated postpaid meters and 35% of respondents do not know how much power they use at home each month or the cost per unit of that electricity. Regarding the respondents, 67% have a prepaid card/electrical meter installed (per kilowatt). Concerning cost, 10% of the respondents spends between N1000-N5000 for their monthly electricity consumption, 27% of the respondents between N5,000 and N10,000, 38% between N10,000 and N17,000, 24% between N17,000 and N25,000 and 2% above N25,000 per month on electricity. These findings will assist effective power distribution within the estate and provide guidance on charge rates for commercial power users which is approximately 28% overall.

This article discusses local political dynamics in Indonesia, notably in the city of Metro. There are several factors why a particular candidate is more politically electable than others, including ethno-religious factors and money. Moreover, a traditional factor that needs to be considered in the study of electoral geography is the influence of the spatial effect upon voting behaviour. In the election, demographics and geography are two important factors in voting behaviour. The local election resulted in a competitive and dynamic political contest among the local elite in Metro. The result of the 2020 local election was particularly interesting because the independent candidate won and defeated the party-based candidate. This is a mixed methods approach combining the data from interviews and a qualitative survey. This research aims to analyse the spatial factor in Metro’s local election, looking at why a certain candidate won in a particular area and how the geographical factor influenced voting behaviour. Secondly, the result of the qualitative survey supported the finding that voters still consider ethno-religious factor. The finding obtained by this research reveals two significant narratives, specifically the crucial factor of ethno-religious sentiment on voting preference and the spatial factor related to residency in securing a victory for the candidate in the local election. Essentially, research concludes that the spatial factor is of importance in the context of Metro’s local election and supports Woolstencroft's (1980) classical concept of electoral geography comprising “friends and neighbours”.

Published: January 2024

O Manual do Professor (MP) da área da Ciências da Natureza e suas Tecnologias (CNT) é originado com a pretensão de auxiliar o professor em sala de aula. É nele que importantes concepções são elucidadas e conhecimentos aprofundados, como a concepção apresentada sobre o método científico. Desse modo, a presente pesquisa objetivou analisar as visões do método científico presentes no MP do Ensino Médio da área de CNT. Trata-se de uma pesquisa qualitativa e a análise ocorreu a partir de três categorias: 1. Construção do conhecimento científico; 2. Experimentação; e 3. Etapas/passos do método; método. Os resultados demonstram que no MP o método científico ainda é abordado com base no Método Hipotético Dedutivo, discutido por Karl Popper, projetando uma visão comum da Ciência para os professores. Para superar essa visão, apresentamos uma proposta didática para a formação continuada de professores da área de CNT.
