The Effects of Oral Probiotics on Type 2 Diabetes Mellitus (T2DM): A Clinical Trial Systematic Literature Review
Authors: Paquette Simon , Thomas Sean C. , Venkataraman Krishnan , Appanna Vasu D. , Tharmalingam Sujeenthar
Published: November 2023

Type 2 diabetes mellitus (T2DM) remains a global health concern. Emerging clinical trial (CT) evidence suggests that probiotic intervention may promote a healthy gut microbiome in individuals with T2DM, thereby improving management of the disease. This systematic literature review summarizes thirty-three CTs investigating the use of oral probiotics for the management of T2DM. Here, twenty-one studies (64%) demonstrated an improvement in at least one glycemic parameter, while fifteen studies (45%) showed an improvement in at least one lipid parameter. However, no article in this review was able to establish a uniform decrease in glycemic, lipid, or blood pressure profiles. The lack of consistency across the studies may be attributed to differences in probiotic composition, duration of probiotic consumption, and probiotic dose. An interesting finding of this literature review was the beneficial trend of metformin and probiotic co-administration. Here, patients with T2DM taking metformin demonstrated enhanced glycemic control via the co-administration of probiotics. Taken together, the overall positive findings reported across the studies in combination with minimal adverse effects constitute ground for further quality CTs. This review provides recommendations for future CTs that may address the shortcomings of the current studies and help to extract useful data from future investigations of the use of probiotics in T2DM management.

Published: November 2023

The aim of the present research is to investigate the effect of different operation variables in the hydrogenolysis of glycerol to 1-propanol and to develop a simple kinetic model useful for the design of the reactor. For this purpose, a carbon-based composite was impregnated with 4 wt.% of Al(H2PO4)3 (CPAl) and used as a support to prepare a Ni catalyst. The support and the catalyst were characterized by BET, XRD, NMR, potentiometric titration, isopropanol decomposition reaction, TEM and TPR analysis. The catalytic tests were carried out at 220–260 °C and 0.5–4 MPa of H2 initial pressure varying the glycerol concentration in aqueous solutions between 30 and 80 wt.%. The presence of aluminum phosphates in the Ni/CPAl catalyst moderates the surface acidity and the formation of Ni2P leads to a high selectivity towards 1-propanol. In this sense, the Ni/CPAl catalyst showed total glycerol conversion and 74% selectivity towards 1-propanol at 260 °C and 2 MPa of H2 initial pressure using 30 wt.% glycerol aqueous solution and 8 h of reaction time. A slight increase in particle size from 10 to 12 nm was observed after a first reaction cycle, but no changes in acidity and structure were observed. Based on these results, a power-law kinetic model was proposed. For glycerol consumption, partial orders of 0.07, 0.68 and −0.98 were determined with respect to glycerol, H2 and water, and an apparent activation energy of 89 kJ mol−1 was estimated. The results obtained indicate that the model fits the experimental concentration values well and can predict them with an average error of less than 7%.

Authors: Li Hengkai , Xu Zikun , Zhou Yanbing , He Xiaoxing , He Minghua
Published: November 2023

An extensive number of farmlands in the Poyang Lake region of China have been submerged due to the impact of flood disasters, resulting in significant agricultural economic losses. Therefore, it is of great importance to conduct the long-term temporal monitoring of flood-induced water body changes using remote sensing technology. However, the scarcity of optical images and the complex, fragmented terrain are pressing issues in the current water body extraction efforts in southern hilly regions, particularly due to difficulties in distinguishing shadows from numerous mountain and water bodies. For this purpose, this study employs Sentinel-1 synthetic aperture radar (SAR) data, complemented by water indices and terrain features, to conduct research in the Poyang Lake area. The results indicate that the proposed multi-source data water extraction method based on microwave remote sensing data can quickly and accurately extract a large range of water bodies and realize long-time monitoring, thus proving a new technical means for the accurate extraction of floodwater bodies in the Poyang Lake region. Moreover, the comparison of several methods reveals that CAU-Net, which utilizes multi-band imagery as the input and incorporates a channel attention mechanism, demonstrated the best extraction performance, achieving an impressive overall accuracy of 98.71%. This represents a 0.12% improvement compared to the original U-Net model. Moreover, compared to the thresholding, decision tree, and random forest methods, CAU-Net exhibited a significant enhancement in extracting flood-induced water bodies, making it more suitable for floodwater extraction in the hilly Poyang Lake region. During this flood monitoring period, the water extent in the Poyang Lake area rapidly expanded and subsequently declined gradually. The peak water area reached 4080 km2 at the height of the disaster. The severely affected areas were primarily concentrated in Yongxiu County, Poyang County, Xinjian District, and Yugan County.

Low-cost, long-term measures of air pollution concentrations are often needed for epidemiological studies and policy analyses of household air pollution. The Washington passive sampler (WPS), an ultra-low-cost method for measuring the long-term average levels of light-absorbing carbon (LAC) air pollution, uses digital images to measure the changes in the reflectance of a passively exposed paper filter. A prior publication on WPS reported high precision and reproducibility. Here, we deployed three methods to each of 10 households in Ulaanbaatar, Mongolia: one PurpleAir for PM2.5; two ultrasonic personal aerosol samplers (UPAS) with quartz filters for the thermal-optical analysis of elemental carbon (EC); and two WPS for LAC. We compared multiple rounds of 4-week-average measurements. The analyses calibrating the LAC to the elemental carbon measurement suggest that 1 µg of EC/m3 corresponds to 62 PI/month (R2 = 0.83). The EC-LAC calibration curve indicates an accuracy (root-mean-square error) of 3.1 µg of EC/m3, or ~21% of the average elemental carbon concentration. The RMSE values observed here for the WPS are comparable to the reported accuracy levels for other methods, including reference methods. Based on the precision and accuracy results shown here, as well as the increased simplicity of deployment, the WPS may merit further consideration for studying air quality in homes that use solid fuels.
Beyond Basics: Can a Driving Simulator Reliably Reproduce Real Vehicle Dynamics?
Authors: Fernandes Beatriz , Macedo Eloisa , Bandeira Jorge M.
Published: November 2023

Despite constant technological innovation, road transport remains a significant source of pollutant emissions, and effective driver-behaviour changes can be considered as solutions that can increase the sustainability of road traffic in a short period. Thus, understanding driver behaviour plays a key role in assessing traffic-related impacts. Since real-world experiments entail some risks and are often not flexible, simulator-based experiments can be relevant to studying vehicle dynamics and driver behaviour. However, the reliability of the simulation results’ accuracy must be ensured. The primary objective of this paper is to present an exploratory analysis focused on the study of the reliability of a driving simulator to reproduce driving parameters that can then be used for emission estimation. For that purpose, tests were conducted by two drivers for urban and highway scenarios performed on a driving simulator and in real-world environments. Different road singularities composed events that were microscopically analysed. Second-by-second vehicle dynamic variables were recorded, and the pollutant emissions were estimated using the vehicle specific power (VSP) methodology. The results of this exploratory validation analysis showed that the total average emissions of all events were not significantly different (958.39 g for simulated and 998.06 g for empirical tests). Overall, the driving simulator can replicate vehicle dynamics from a microscopic perspective, especially for the urban scenario. This may be due to the more complex traffic conditions and road specificities that require more restrained driving behaviour. Nevertheless, VSP mode distributions did not follow the same pattern in 4 out of 10 events, meaning that the drivers displayed different behaviours in the simulated and empirical tests for those events. The relative errors range between 4 and 29% for carbon dioxide emissions and between 2 and 33% for nitrogen oxides emissions.
Multi-Domain Rapid Enhancement Networks for Underwater Images
Authors: Zhao Longgang , Lee Seok-Won
Published: November 2023

Images captured during marine engineering operations suffer from color distortion and low contrast. Underwater image enhancement helps to alleviate these problems. Many deep learning models can infer multi-source data, where images with different perspectives exist from multiple sources. To this end, we propose a multichannel deep convolutional neural network (MDCNN) linked to a VGG that can target multi-source (multi-domain) underwater image enhancement. The designed MDCNN feeds data from different domains into separate channels and implements parameters by linking VGGs, which improves the domain adaptation of the model. In addition, to optimize performance, multi-domain image perception loss functions, multilabel soft edge loss for specific image enhancement tasks, pixel-level loss, and external monitoring loss for edge sharpness preprocessing are proposed. These loss functions are set to effectively enhance the structural and textural similarity of underwater images. A series of qualitative and quantitative experiments demonstrate that our model is superior to the state-of-the-art Shallow UWnet in terms of UIQM, and the performance evaluation conducted on different datasets increased by 0.11 on average.
Acoustic-Sensing-Based Attribute-Driven Imbalanced Compensation for Anomalous Sound Detection without Machine Identity
Authors: Zhou Yifan , Long Yanhua , Wei Haoran
Published: November 2023

Acoustic sensing provides crucial data for anomalous sound detection (ASD) in condition monitoring. However, building a robust acoustic-sensing-based ASD system is challenging due to the unsupervised nature of training data, which only contain normal sound samples. Recent discriminative models based on machine identity (ID) classification have shown excellent ASD performance by leveraging strong prior knowledge like machine ID. However, such strong priors are often unavailable in real-world applications, limiting these models. To address this, we propose utilizing the imbalanced and inconsistent attribute labels from acoustic sensors, such as machine running speed and microphone model, as weak priors to train an attribute classifier. We also introduce an imbalanced compensation strategy to handle extremely imbalanced categories and ensure model trainability. Furthermore, we propose a score fusion method to enhance anomaly detection robustness. The proposed algorithm was applied in our DCASE2023 Challenge Task 2 submission, ranking sixth internationally. By exploiting acoustic sensor data attributes as weak prior knowledge, our approach provides an effective framework for robust ASD when strong priors are absent.

This manuscript describes the design, development, and implementation of a prototype system based on seismogeodetic techniques, consisting of a low-cost MEMS seismometer/accelerometer, a biaxial inclinometer, a multi-frequency GNSS receiver, and a meteorological sensor, installed at the Doñana Biological Station (Huelva, Spain) that transmits multiparameter data in real and/or deferred time to the control center at the University of Cadiz. The main objective of this system is to know, detect, and monitor the tectonic activity in the Gulf of Cadiz region and adjacent areas in which important seismic events occur produced by the interaction of the Eurasian and African plates, in addition to the ability to integrate into a regional early warning system (EWS) to minimize the consequences of dangerous geological phenomena.
Quantifying Digital Biomarkers for Well-Being: Stress, Anxiety, Positive and Negative Affect via Wearable Devices and Their Time-Based Predictions
Authors: Saylam Berrenur , İncel Özlem Durmaz
Published: November 2023

Wearable devices have become ubiquitous, collecting rich temporal data that offers valuable insights into human activities, health monitoring, and behavior analysis. Leveraging these data, researchers have developed innovative approaches to classify and predict time-based patterns and events in human life. Time-based techniques allow the capture of intricate temporal dependencies, which is the nature of the data coming from wearable devices. This paper focuses on predicting well-being factors, such as stress, anxiety, and positive and negative affect, on the Tesserae dataset collected from office workers. We examine the performance of different methodologies, including deep-learning architectures, LSTM, ensemble techniques, Random Forest (RF), and XGBoost, and compare their performances for time-based and non-time-based versions. In time-based versions, we investigate the effect of previous records of well-being factors on the upcoming ones. The overall results show that time-based LSTM performs the best among conventional (non-time-based) RF, XGBoost, and LSTM. The performance even increases when we consider a more extended previous period, in this case, 3 past-days rather than 1 past-day to predict the next day. Furthermore, we explore the corresponding biomarkers for each well-being factor using feature ranking. The obtained rankings are compatible with the psychological literature. In this work, we validated them based on device measurements rather than subjective survey responses.
Fast DOA Estimation Algorithms via Positive Incremental Modified Cholesky Decomposition for Augmented Coprime Array Sensors
Authors: Song Jing , Cao Lin , Zhao Zongmin , Wang Dongfeng , Fu Chong
Published: November 2023

This paper proposes a fast direction of arrival (DOA) estimation method based on positive incremental modified Cholesky decomposition atomic norm minimization (PI-CANM) for augmented coprime array sensors. The approach incorporates coprime sampling on the augmented array to generate a non-uniform, discontinuous virtual array. It then utilizes interpolation to convert this into a uniform, continuous virtual array. Based on this, the problem of DOA estimation is equivalently formulated as a gridless optimization problem, which is solved via atomic norm minimization to reconstruct a Hermitian Toeplitz covariance matrix. Furthermore, by positive incremental modified Cholesky decomposition, the covariance matrix is transformed from positive semi-definite to positive definite, which simplifies the constraint of optimization problem and reduces the complexity of the solution. Finally, the Multiple Signal Classification method is utilized to carry out statistical signal processing on the reconstructed covariance matrix, yielding initial DOA angle estimates. Experimental outcomes highlight that the PI-CANM algorithm surpasses other algorithms in estimation accuracy, demonstrating stability in difficult circumstances such as low signal-to-noise ratios and limited snapshots. Additionally, it boasts an impressive computational speed. This method enhances both the accuracy and computational efficiency of DOA estimation, showing potential for broad applicability.

Published: November 2023

Given the advantages of readily availability, low cost, convenient operation, and large adsorption capacity, brown seaweed has been studied extensively as a biosorbent for heavy metal remediation from aqueous media. Herein, raw Lessonia nigrescens and brown seaweed residue, a waste product from the manufacturing of alginate from L. nigrescens, were employed as low-cost and renewable adsorption materials for effective copper removal in wastewater streams. The influences of temperature, sample loadings, adsorption time, initial metal ion concentrations, and pH on the efficiency of the metal ions adsorption process were investigated. The thermodynamics and kinetics of Cu (II) adsorption for both the raw seaweed and seaweed residue were studied in order to determine the maximum removal efficiency and capacity. The characterization of the seaweed and seaweed residue before and after copper adsorption with SEM, FTIR, EDS, etc., coupled with the thermodynamics study, confirmed the ion exchange mechanism involved in the adsorption process. Under optimal conditions, the removal efficiencies were 75% and 71% for L. nigrescens and seaweed residue, respectively, and the adsorption capacities can reach 12.15 mg/g and 9.09 mg/g within 10 min for L. nigrescens and seaweed residue, respectively. The slight reduction in removal efficiency was because the active ion exchange sites were partially removed during the alginate extraction. The comparable metal ion removal efficiency between raw seaweed and seaweed residue suggesting the L. nigrescens residue is viable as bio-adsorbent and potential for industrial applications in adsorption process. The results provided a novel way to upgrade seaweed biomass in a biorefinery concept.

У світовій практиці штампові вставки на 70% виготовляють способами лиття, при цьому спостерігається тенденція до зниження використання поковок та сортового прокату. З точки зору ливарного виробництво, процес виготовлення цих деталей представляє ряд складнощів. Для їх виготовлення використовують середньо- та високолеговані, часто комплексно леговані сталі. Вони зумовлюють високі вимоги до термічної та фізико-хімічної стійкості ливарних форм. Тому створення нових матеріалів, у першу чергу високоефективних зв’язувальних компонентів для ливарних форм, є актуальним завданням. Як властивості металу формуються на базі його кристалічної структури, так і властивості формувальної (стрижневої) суміші формуються на мікрорівні, в результаті взаємодії зернової основи та плівок зв’язувального компонента між собою. Таким чином, забезпечення належного рівня властивостей сумішей для ливарних стрижнів є шляхом до забезпечення якості форми в цілому і якості отримуваних литих заготовок. Статтю присвячено дослідженню властивостей стрижневих сумішей, які містять зв’язувальні компоненти, синтезовані за оригінальними технологіями з ортофосфорної кислоти та ряду добавок. Серед них пилоподібні вогнетривкі наповнювачі (кварц, циркон, пірофіліт, дистен-силіманіт), а також концентрат алюмінієвих шламів та сульфат алюмінію. Суміші тверднуть при нагріванні в інтервалі від 200 до 300 оС. В роботі було визначено міцність зразків даних сумішей при стисканні і при розриванні, встановлено співвідношення між цими характеристиками. Також визначено важливі властивості запропонованих сумішей з точки зору усунення газових та поверхневих дефектів литих заготовок – газопроникність і газотвірність. Властивості досліджуваних стрижневих сумішей визначали за стандартними методиками та на стандартних зразках, прийнятих для ливарного виробництва. Газотвірну здатність визначено непрямим методом нагрівання проб сумішей до 1000 оС та фіксацією об’єму виділених із проби газоподібних речовин. Встановлено, що за комплексом властивостей представлені суміші можуть бути рекомендовані для виготовлення ливарних стрижнів під час отримання виливків із залізовуглецевих сплавів, у т ч. литих заготовок штампового інструменту з легованих сталей.

Published: November 2023

Apologetika Kristen adalah suatu cabang ilmu sistematis yang mempertahankan dan menjelaskan iman dan kepercayaan Kristen. Orang yang ahli dalam bidang ilmu ini disebut sebagai apologis Kristen, tetapi sebenarnya setiap orang Kristen adalah apologet kristen. Apologetika adalah suatu ilmu terapan dalam kaitannya dengan pembelaan iman Kristen yang dalam agama Kristen, pembelaan intelektual terhadap kebenaran agama Kristen biasanya dianggap sebagai cabang teologi. Dalam kalangan Protestan, apologetika dapat dibedakan dari polemik, di mana keyakinan gereja Kristen tertentu dipertahankan. Akan tetapi, umat Katolik Roma menggunakan istilah tersebut untuk mengartikan pembelaan terhadap ajaran Katolik secara keseluruhan dan menyamakan apologetika dengan teologi fundamental. Apologetika dimengerti sebagai ilmu mengenai pembelaan iman Kristen yang berusaha untuk menjawab pernyataan sikap dari para skeptisisme yang meragukan keberadaan Allah atau menyerang kepercayaan kepada Allah yang terdapat dalam Alkitab. Dengan metode kualitatif, penulis meneliti bagaimana tindakan pembelaan iman ini dapat ditunjukkan juga kepada pemeluk agama yang lain, aliran kristen liberal yang lain, orang kristen sendiri yang ragu-ragu terhadap kebenaran Alkitab. Praktik apologetika diperlukan dalam kaitan mempertanggungjawabkan iman dan menghindari bahaya murtad.

Abstract:This paper will examine the idea of Christ as the Head of all things in Ephesians 1:10, 22. The idea of Christ as the Head of all things does not contain Christ's dominance over the universe. This idea is panentheism, in the way that Christ is at the same time the Head of the church and of the universe. This idea provides the theological foundation for a missional church. The church's mission is one of the manifestations of missio Dei in this world because this concept teaches the church to direct its mission to the whole world. Keywords: Body of Christ; Christ; head of the church; head of all the things; panentheism; embrace; love; a missionary church Abstrak:Tulisan ini akan mengkaji gagasan Kristus sebagai Kepala segala sesuatu dalam Efesus 1: 10, 22. Gagasan Kristus sebagai Kepala segala sesuatu tidak mengandung dominasi Kristus terhadap alam semesta. Gagasan ini mengandung panenteisme sehingga Kristus sebagai Kepala gereja dan sekaligus segala sesuatu merengkuh alam semesta dalam diri-Nya dengan kasih. Gagasan ini menjadi landasan teologis untuk gereja yang misional. Gereja yang misional menjadi salah satu perwujudan missio Dei di dunia ini karena konsep ini mengajarkan gereja untuk mengarahkan misinya ke seluruh dunia. Kata kunci : Tubuh Kristus; Kristus; Kepala gereja; Kepalasegala sesuatu; panenteisme; merengkuh; kasih; gereja yang misional

Lately, religion has become something scary and worrying. Religion in the hands of its followers often appears with a face full of violence and as if it has lost its friendliness. In recent years, there have been many conflicts, intolerance and violence in the name of religion and belief. Religious pluralism is not a reality that requires people to put each other down, belittle each other, or confuse one religion with another, but instead places it in a position of mutual respect, mutual recognition and cooperation. In order to eliminate the destructive aspects of religion and present its constructive side as a unifier, schools as institutions mandated to educate the nation's life must participate in providing an understanding of religion and must be able to create an environment that provides education. Opportunities for students to build harmonious social relationships between students of different religions. For this reason, an effort is needed in certain religious communities to reflect or think coherently about the new awareness as an effort to respond to this problem of pluralism. To address this matter, Religionum Theology as a branch of theology that discusses how Christianity responds to the reality of the existence of religious plurality outside itself, especially in Christian Religious Education.
Makna ἐν Χριστῷ Menurut Paulus dalam Surat 2 Korintus 5:17 Bagi Orang Percaya
Authors: Tami Tami
Published: November 2023

Abstract:Phrase “It is in Christ (ἐν Χριστῷ)” appears a great many times in the New Testament especially in the books written by Paul. "It is in Christ" is no longer a foreign thing to Christianity today. So this becomes an important topic to be interpreted well; lived and lived earnestly in other words until it became an expression or lifestyle of a true Christian faith. For the significance of living faith is that which leads one to the knowledge of the true Jesus Christ that is; in His death, burial, and resurrection. And this is the saving faith. To be a follower of Jesus Christ is to continue the process of purifying oneself by the work of the Holy Spirit through baptism, repentance every day. From there it was later refined and became a new creation. The new creation in Jesus (ἐν Χριστῷ), that is, to leave "the old" (the old man) and "the new one has come" into the "new man". This new creation is closely related to a change in action, a change in mindset or a Christ-centered perspective. Just as it was Christ who became the center of life and came to life with Christ or achieved the theosis that was the purpose of God creating man.Abstrak:Frasa “berada di dalam Kristus (ἐν Χριστῷ)” ada banyak sekali muncul di dalam Perjanjian Baru khususnya dalam kitab-kitab yang ditulis oleh Paulus. “Ada di dalam Kristus” bukan lagi hal yang asing bagi Kekristenan dewasa ini. Sehingga ini menjadi suatu topik penting untuk dimaknai dengan baik; dihayati dan dihidupi dengan sungguh-sungguh dengan kata lain sampai menjadi sebuah ekpresi atau gaya kehidupan iman Kristen yang sejati. Karena signifikansi daripada iman yang hidup adalah iman yang menuntun seseorang pada pengenalan akan Yesus Kristus yang benar yaitu; di dalam kematian, penguburan, dan kebangkitan-Nya. Dan inilah iman yang menyelamatkan. Menjadi pengkut Yesus Kristus berarti terus berproses menyucikan diri oleh karya Roh Kudus melalui baptisan, pertobatan setiap hari. Dari situlah kemudian dilahirbarukan dan menjadi ciptaan baru. Ciptaan baru di dalam Yesus (ἐν Χριστῷ), yaitu meninggalkan “yang lama” (manusia lama) dan “yang baru sudah datang” menjadi “manusia baru”. Ciptaan baru ini berkaitan erat dengan perubahan tindakan, perubahan pola pikir (mindset) atau cara pandang yang berpusat pada Kristus. Sebagaimana Kristuslah yang menjadi pusat hidup dan manunggal dengan Kristus atau mencapai theosis itulah tujuan Allah menciptakan manusia.

The fact is that there are many families who are always in conflict and fight, even to the point of divorce. Realizing this, a relevant and contextual hermeneutical study methodology is needed to be able to understand various cases. Through this methodology, each case is reviewed flexibly according to the essence and available information from the case itself. Then this flexibility value will bring up new themes and can be combined into a new substance from the scientific field that is more actual and contextual. Thus, the fruit of this contextual study will help church workers and lay congregations in their efforts to find solutions to problems in the family environment from a broader perspective.
Analisis Permasalahan Pelayanan Diakonia Transformatif Di Jemaat GMIT Sion Loti
Authors: Nulik Eritrika Adriana , Koli Endang Damaris
Published: November 2023

Artikel ini menganalisis permasalahan yang berkaitan dengan pemahaman pelayanan diakonia transformatif di jemaat GMIT Sion-Loti. Diakonia transformatif merupakan pendekatan pelayanan gereja yang berfokus pada perubahan sosial kemasyarakatan. Penelitian ini mengidentifikasi tantangan dalam pemahaman dan implementasi pelayanan diakonia transformatif dan faktor-faktor yang memengaruhi pemahaman tersebut. Melalui pendekatan kualitatif, data dikumpulkan melalui wawancara mendalam dan observasi partisipatif terhadap anggota jemaat dan para majelis jemaat. Hasil analisis menunjukkan bahwa permasalahan utama terletak pada pemahaman yang terbatas mengenai esensi diakonia transformatif. Banyak anggota jemaat masih mengaitkan pelayanan diakonia dengan bantuan material, tanggung jawab pihak lain dan bersifat sukarela semata. Faktor budaya, ego, dan kepemimpinan juga memengaruhi persepsi terhadap pelayanan diakonia, mengakibatkan penghalangan dalam mengadopsi pendekatan transformatif. Artikel ini menyimpulkan bahwa diperlukan upaya edukasi dan pelatihan yang lebih intensif untuk meningkatkan pemahaman mengenai diakonia transformatif. Jemaat perlu diikutsertakan dalam dialog dan refleksi kolektif mengenai relevansi pelayanan diakonia transformatif dalam konteks lokal mereka. Selain itu, dukungan dari pihak gereja dalam membentuk budaya pelayanan yang berfokus pada transformasi dapat membantu mengatasi permasalahan yang diidentifikasi.
