Authors: Wibowo Antonia Rahayu Rosaria
Published: December 2022

The use of internet has grown massively since 1990s. It has brought both life improvement and criminal activities in cyberspace. The cyberattack has affected most sectors including space sector. The space sector is vulnerable to cyberattacks because a lot of human technologies depend on it. The actors behind it cannot be identified as an individual based on geographical location, so that, global effort is needed. The importance of global effort to secure space sector from cyberattacks is discussed in this paper. This paper used the descriptive method and library research techniques to collect data. Data about cyberattack on space sector and efforts to secure them were collected from academic journals and international organizations� documents. Then, they were analyzed using the global governance theory. The result shows that global effort to secure space sector from cyberattack is important because it is a transnational problem, furthermore space sector connects modern infrastructures worldwide.

Published: December 2022

Si bien la adaptación al cambio climático se concentra en la revolución tecnológica de energías verdes llamada adaptación gris, aún quedan por explorar las poco mencionadas adaptaciones verde e híbrida, correspondientes a prácticas como el ecoturismo. Por lo tanto, este trabajo busca destacar la adaptación a través del ecoturismo.  Debido a que no existe un manual exclusivo sobre la adaptación al cambio climático y turismo, se adaptó la metodología de análisis multicriterio propuesta por la Sociedad Alemana de Cooperación Internacional, cuyos criterios son seleccionados a través de indicadores con ayuda de los métodos A.D.A.P.T. y Delphi, y en el cual 30 expertos de categoría internacional evalúan 983 indicadores. Los resultados representan un aporte significativo a la adaptación al cambio climático y turismo al obtener 25 indicadores precisos, así como la discusión sobre la dificultad y el desorden de los indicadores propuestos por manuales internacionales que podrían ocasionar una mala adaptación, la dificultad para tomar decisiones y la selección de medidas erróneas. Por último, subrayamos la necesidad de recuperar el verdadero ecoturismo e implementarlo como medida de adaptación.
Judges' Considerations in Granting Permission to Underage Marriage Applications at the Luwuk Religious Court
Authors: Sustiono N. A. , Marzuki Marzuki , Ibrahim Sidik
Published: December 2022

This study discusses judges’ considerations in granting requests for underage marriages permission at the Luwuk Religious Court. This study used a qualitative method. The data was collected through direct observation, in-depth interviews, and written document analysis. The data, then, was analyzed using thematic analysis to find themes from the data. The results of this study show that the procedure for submitting a marriage dispensation at the religious court is the same as the mechanism for filing other application cases. Increasing the minimum age for marriage for women to 19 years impacted the increase cases of underage marriage dispensation applications  at the Religious Courts. The filing of a underage marriage dispensation case in the Religious Courts was caused by preventive  and curative factors. The basis used by the judge in deciding the application for underage marriage dispensation is based on the theory of law enforcement. Then there must be considerations encouraging the judge to grant the application for underage marriage dispensations. The factors considered by judges in determining the dispensation of marriage were also related to psychological, health, educational, and economic factors. These four factors were taken into serious consideration by the judge in determining the dispensation of marriage. Based on the results, we recommend the religious courts should be more selective in examining, considering, and determining applications for underage marriage dispensation to prevent social conflicts and the impact of these decisions to society.

Published: December 2022

This study aims to analyze the marriage customs of the Saluan Tribe in the perspective of Islamic law in Banggai Regency. The analysis of this research includes the implementation of marriage according to the custom of the Saluan tribe, Banggai Regency and a review of Islamic law on the implementation of the traditional marriage of the Saluan tribe. The research used a qualitative method with data collection techniques used namely observation, in-depth interviews and review of written documents. The data were analyzed using data reduction techniques, data presentation, data verification and drawing conclusions. The results of the study show that the implementation of the traditional marriage of the Saluan tribe in Banggai district begins with the Montoi date or determines the wedding date. Then, the marriage process is continued with exploratory (popitoi), proposed marriage (Monsodoi), marriage deliberation (Mobisalakon Saibatanggo). The final process of the traditional marriage of the Saluan tribe is escorting the bride (Menggundulkan Mangantokon) to the man to get married (Akad Nikah) and visit the parents-in-law's house (Mobilangi Tama).The traditional marriage of the Saluan tribe from the perspective of Islamic law is in accordance with Islamic law. When viewed from a maqâṣidalshariah perspective, the marriage process of the Saluan tribe also does not violate Islamic law because the purpose of the traditional marriage procession is to preserve life and property. This research contributes to people's understanding of the history or origins of the Saluan tribal traditional marriage tradition. Then this research can also contribute to the preservation of the customs of the Saluan tribe regarding marriage.

Authors: Olubisi Ewuola Emmanuel , Queen-Esther Alegbejo , Toluwani Akinbola Elizabeth
Published: December 2022

Haemo-thermoregulatory response of twenty-six adult geese comprising of 12 males and 14 females randomly allotted to four groups (Wallowed males, non-wallowed males, wallowed females and non-wallowed females) in a completely randomized design for seven weeks was evaluated. Wallowing was done every alternate day. Respiratory rate (RR), rectal temperature (RT) and pulse rate (PUR) were recorded. On days 1 and 49, blood samples (3mL/geese) were collected from geese in each group and analysed for haematological parameters using standard procedures. There was no sex effect on the RR and PUR but significantly (p<0.05) higher RT was observed in males (40.69°C) compared to females (40.53°C). The RR, RT and PUR were not significantly affected by wallowing. Interactions effect between sex and wallowing on RR, RT and PUR was not significant. Only platelet counts were significantly higher in females (17.70) than males (14.68). Wallowed Geese had significantly lower packed cell volume (37.46±5.13%), haemoglobin (11.85±1.69g/dl) and monocytes (2.81±0.63%) than other treatments. Wallowed Female geese had significantly lower haemoglobin (10.93g/dL) and monocytes (2.86%) compared to those without wallow treatment. Therefore, wallowing has mild influence on the thermoregulatory and haematological indices of geese reared under low temperature-humidity index during non-breeding season.

Published: December 2022

The study evaluated the effect of Vernonia amygdalina leaf meal on semen indices, serum testosterone and sperm reserve of male rabbits. Forty rabbit bucks were randomly assigned into four groups and fed the experimental diets containing Vernonia amygdalina (VLM) at 0, 5, 10 and 15 % levels for 84days. Reproductive indices were evaluated using standard procedures. Data obtained were subjected to analysis of variance at p<0.05. All semen in rabbits fed 0, 5 and 10 % VLM had milky colour while 14.8% light green and 85.2% milky semen colour was observed in bucks fed 15%VLM. Libido score reduced in rabbits fed VLM diets. Bucks fed 15%VLM had significantly higher semen volume (0.47ml). VLM had no significant effect on spermatozoa mass motility, progressive motility and sperm concentration. Live sperm cells significantly increased in bucks fed 5 and 10% VLM diets. VLM had significant (p<0.05) effect on spermatozoa morphology. Vernonia amygdalina leaf meal had no significant (p<0.05) impact on testosterone, testicular and epididymal indices. In conclusion, up to 10%VLM can be adopted as feed ingredient for male rabbit breeder stock without deleterious effect on reproductive indices.
News Media Brand Equity in a New Media Environment
Authors: Saulite Linda
Published: December 2022

Digitalisation has profoundly altered how media are distributed and audiences consume media information, reshaping the media environment and introducing new competitors to media brands. This new media environment deludes media brand associations, contributing to an environment where audiences care less about content sources or brands of media. The younger audience, Generation Z, is an even more platform-on-demand and experience-driven audience. They favour social media and global media and care less about national media brands. Media consumption trends among youthful audiences have become crucial as the sector recognises this audience as a significant portion of the market today and signalling media consumption trends after coming generations. This study examines the impact of news media attributes and perceived uniqueness on news media brand equity in the new media environment. The study emphasises media brand distinctiveness and its effect on news media brand equity. The decision tree method is applied to predict the most significant news media attributes contributing to news media brand equity and the perceived uniqueness of the news media brand. Research results demonstrate the influence of content-consumption-related brand attributes and uniqueness on media brand equity.
Impact of Covid-19 on SMMEs and the future sustainability measures: a systematic review
Authors: Enwereji Prince Chukwuneme
Published: December 2022

Small Medium and Micro Enterprises (SMMEs) have made remarkable contributions to enhancing the economic growth of South Africa. The emergence of COVID-19 retarded the growth of SMMEs due to the lockdown imposed by the government on the 23rd of March, 2020. This study investigated the impact of COVID-19 on SMMEs and the future sustainability measures. To achieve the objectives of this study, a systematic review was adopted and 150 articles were downloaded from various databases for the study. Findings obtained from the study revealed that several authors from different continents have made wide contributions to revive SMMEs amidst COVID-19 disruption. The recommendations made to SMMEs include amplifying their communication networks and adopting e-commerce options, as well as Social Network Sites to reach out to their customers. Other recommendations include the adoption of transactional leadership, strategic management, employee management, financial management, and effective collaboration. The study further recommended that the government should endeavour to provide funding opportunities to SMMEs, improve the provision of infrastructure and enhance the effectiveness of the business environment. The study concludes that the SMMEs that were affected by the interruption of COVID-19 would be revived if the recommendations of this study are applied.
Finding theAxis Mundiin an Undergraduate Classroom
Authors: Pruett Dave
Published: December 2022

Humanity is in a tight race between planetary catastrophe and enlightenment. It’s not clear which will prevail. The old paradigm, that of materialism, individualism, and fierce competition, is failing at all levels—economic, social, political, and environmental—and bringing life as we know it to the edge of a precipice. At the same time, a “new” paradigm is emerging, one that emphasizes interconnectedness, the sacredness of all creation, universal consciousness, and cooperation. In truth, the “new” paradigm is anything but new. What’s new is that scientific discoveries are now beginning to resonate with and reinforce ancient wisdom, wisdom that has been imbedded in indigenous mythologies for millennia. It’s incumbent upon those who have already transitioned to a more sustainable “myth of meaning” to find ways to encourage others along the path. A demographic naturally resonant to holistic worldviews, but largely untapped, is that of undergraduate Honors students. This paper describes a pioneering Honors course at James Madison University that, by many measures, has succeeded in integrating science and spirituality into a new way of thinking and being.

Authors: Borchardt Miriam , Pereira Giancarlo M. , Milan Gabriel S. , Scavarda Annibal R. , Nogueira Edithe O. , Poltosi Leonel C.
Published: December 2022

Background/purpose: In comparison to Industry 4.0 (I4.0), Industry 5.0 (I5.0) shows a more systemic transformation that includes business innovations driving the transition to a sustainable, human-centric, and resilient industry. I5.0 implies on rethinking business models, ecosystems, managerial practices, etc. while moving toward sustainable development. Despite the novelty of I5.0 and the growing interest in the subject, the literature is still scarce. Therefore, this study aims to analyze the state of the art and understand the approaches that constitute the study of I5.0, through the lens of business and operations management.

Method: A systematic literature review was performed through the lens of the business and operations management literature.

Results: Four major themes were identified: (i) technological application, (ii) Human Resources and workers, (iii) education, and (iv) business and operations management. For each theme, the implications, future avenues and practical considerations are presented.

Conclusions: Most I5.0 studies have focused on Human Resources and workers discussing the role of technological applications on operator safety. Despite I5.0 calls for a step forward in sustainable development, studies on it are scarce. Also, the literature is still missing practical contributions and frameworks for how I5.0 could impact on business management.
An Outline of Certain Generic Values - Work Dimensions
Authors: Fehér János
Published: December 2022

Background/Purpose: Values-related issues have come into the focus of leadership thinking in the past few decades and it seems to be paradoxical why values work has not been more extensively used so far for defining and conceptualizing leadership. A reason for this can be that values-oriented research streams normally approach leadership from specific perspectives of values representation and transfer. Alternatively, this study examines values work from a generic perspective. Its goal is to suggest a generalized notion for values work and outline certain generic values-work dimensions.

Methods:Analysis in this theoretical paper is primarily based on Institutional, New Leadership, and Values-Oriented theories. Methods include argumentation and analytical framework development.

Results: This study presents a structured list of and an illustrative framework for some of the dimensions of values work as broadly defined and has research implications regarding issues of leadership influence and the demarcation of leadership from management.

Conclusion: The importance of values representation in contrast to power/influence perspectives in leadership is underlined. Our study points to the necessity for more research on generic aspects of values work. The results can also be used for leadership practice, consulting, and development.

Published: December 2022

Background

Reliable predictors are urgently needed to identify stage II nasopharyngeal carcinoma (NPC) patients who could benefit from concurrent chemoradiotherapy (CCRT). We aimed to develop a nomogram integrating MRI-identified multidimensional features of lymph nodes to predict survival and assist the decision-making of CCRT for stage II NPC.

Patients and methods

This retrospective study enrolled 242 stage II NPC patients treated from January 2007 to December 2017. Overall survival (OS) was the primary endpoint. Performance of nomogram was evaluated using calibration curves, Harrell Concordance Index (C-index), area under the curve (AUC) and decision curves analysis (DCA) and was compared with TNM staging. According to the individualized nomogram score, patients were classified into two risk cohorts and therapeutic efficacy of CCRT were evaluated in each cohort.

Results

Three independent prognostic factors for OS: age, number and location of positive lymph nodes were included into the final nomogram. T stage was also incorporated due to its importance in clinical decision-making. Calibration plots demonstrated a good match between the predicted and our observed OS rates. C-index for nomogram was 0.726 compared with 0.537 for TNM staging (p < 0.001). DCAs confirmed the superior clinical utility of nomograms compared with TNM staging. CCRT compared to intensity-modulated radiotherapy (IMRT) delivered OS benefit to patients in the high-risk group (5-year: 89.9% vs. 72.1%; 10-year: 72.5% vs. 34.2%, p = 0.011), but not in the low-risk group.

Conclusions

This lymph node features-based nomogram demonstrated excellent discrimination and predictive accuracy for stage II patients and could identify patients who can benefit from CCRT.
Imaging perfusion changes in oncological clinical applications by hyperspectral imaging: a literature review
Authors: Hren Rok , Sersa Gregor , Simoncic Urban , Milanic Matija
Published: December 2022

Background

Hyperspectral imaging (HSI) is a promising imaging modality that uses visible light to obtain information about blood flow. It has the distinct advantage of being noncontact, nonionizing, and noninvasive without the need for a contrast agent. Among the many applications of HSI in the medical field are the detection of various types of tumors and the evaluation of their blood flow, as well as the healing processes of grafts and wounds. Since tumor perfusion is one of the critical factors in oncology, we assessed the value of HSI in quantifying perfusion changes during interventions in clinical oncology through a systematic review of the literature.

Materials and methods

The PubMed and Web of Science electronic databases were searched using the terms “hyperspectral imaging perfusion cancer” and “hyperspectral imaging resection cancer”. The inclusion criterion was the use of HSI in clinical oncology, meaning that all animal, phantom, ex vivo, experimental, research and development, and purely methodological studies were excluded.

Results

Twenty articles met the inclusion criteria. The anatomic locations of the neoplasms in the selected articles were as follows: kidneys (1 article), breasts (2 articles), eye (1 article), brain (4 articles), entire gastrointestinal (GI) tract (1 article), upper GI tract (5 articles), and lower GI tract (6 articles).

Conclusions

HSI is a potentially attractive imaging modality for clinical application in oncology, with assessment of mastectomy skin flap perfusion after reconstructive breast surgery and anastomotic perfusion during reconstruction of gastrointenstinal conduit as the most promising at present.
Is Nuclear Anarchy Sustainable? A Temporal Approach
Authors: Uchaev Ye. I. , Kvartalnov A. A.
Published: December 2022

The article develops a novel temporal approach to the sustainability of nuclear anarchy. The extant literature offers two opposite perspectives on the topic: some scholars argue that nuclear anarchy is unsustainable, since it will inevitably either lead to a catastrophic nuclear war or evolve into a hierarchical world order. Their opponents doubt the inevitability of nuclear war in a system of sovereign states and/or its catastrophic nature. However, the debate, as it stands now, ignores the fact that both technology and social structures are embedded in – and mediated by – cultures and worldviews. In particular, both nuclear weapons and interstate anarchy are embedded in specific temporalities.

Taking this fact into account, we identify and compare perceptions of time that are interrelated with nuclear weapons, on one hand, and international anarchy, on the other. The article reveals a temporal contradiction of nuclear anarchy: while nuclear weapons imply a potential finitude of humanity, the system of sovereign states is intrinsically connected with an indefinite temporality. We derive two theoretical implications form the concept of temporal contradiction. First, a realization of finite temporality should subvert the legitimacy of an anarchic world order and encourage limitations on national sovereignty. Second, international anarchy should ‘eternalize’ nuclear weapons, i.e., reinterpret them as compatible with the eternity of human civilization. Familiar events of nuclear history including early attempts to establish international control of nuclear energy, the Strategic Defense Initiative, and the evolution of the anti-nuclear movement are interpreted here as empirical evidence in favor of the theoretical implications described above.

Thus, the concept of temporal contradiction provides another argument in favor of the idea that nuclear anarchy is unsustainable in the long run, since the proliferation of the finite temporality leads to international hierarchy, whereas persistent indefinite temporality masks the severity of the nuclear threat, making nuclear war more conceivable and probable.
Improved Outcomes Following a Care Guideline Implementation: Part 1 of an Analysis of 12 355 Patients After Total Knee Arthroplasty

Published: December 2022

OBJECTIVE: To describe the application and examine the influence of a continuous quality improvement intervention, which had a goal of standardizing care to reduce the proportion of patients who do not have a meaningful improvement in patient-reported outcomes following total knee arthroplasty (TKA).

DESIGN: Continuous quality improvement.

METHODS: A physical therapy (PT) care guideline was initiated in 2013 for patients following TKA. The Knee Outcome Survey – Activities of Daily Living (KOS-ADL) was measured at every visit, and scores were extracted from a clinical outcomes database to calculate the proportion of patients who did not achieve a minimal clinically important difference. Based on logistic regression analysis, we compared the proportion of patients who did not progress on the KOS-ADL in a non-care guideline group (2008–2012) to a care guideline (CG) group (2014–2019).

RESULTS: This study included 12 355 patients (aged 18–92 years) following TKA incurring at least 3 PT visits from 2008 to 2019. The percentage of patients who did not progress in the non-care guideline group was 25.8% and in the care guideline group 14.3% (P<0.001). The relationship between care guideline adherence and lack of progression on the KOS-ADL was statistically significant, X2 (df = 1) = 148.7, P<.001.

CONCLUSION: The percentage of patients who did not achieve meaningful progress on the KOS-ADL declined significantly in the 6 years after implementing a TKA care guideline without an increase in the number of clinical visits. The standardized care guideline was associated with meaningful improvements for patients following TKA when applied in conjunction with PT access to outcome data, feedback through audits, performance goals, and financial incentives.

OBJECTIVE: To describe the variation in outcomes and number of visits before and after implementing a care guideline for total knee arthroplasty (TKA) rehabilitation.

DESIGN: Nonrandomized intervention study.

METHODS: We compared 2558 patients with TKA who received care that was not standardized (non-care guideline [NCG] group) to 9797 patients with TKA who received care according to the care guideline (CG). We fit 2 Bayesian hierarchical linear regression models using the Knee Outcome Survey – Activities of Daily Living (KOS-ADL) change score and number of physical therapy (PT) visits as the response variables, controlling for relevant predictor variables. We also compared the ratio of the standard deviations of the KOS-ADL change scores and the number of PT visits within and between clinics.

RESULTS: The overall estimated mean improvement in KOS-ADL change score was 23.0 points (95% confidence interval [CI]: 20.3, 25.7) in the NCG group and 28.7 points (95% CI: 27.5, 29.7) in the CG group; the mean difference was 5.6 (2.7–8.6). Mean KOS-ADL change scores were higher in the CG group than the NCG group in every clinic, although only 8 clinics improved significantly. The number of PT visits did not change meaningfully (NCG: mean, 10.7 [95% CI: 9.9, 11.5]; CG: mean, 10.5 [95% CI: 9.9, 10.9]). Variation in KOS-ADL change score decreased by 4% within clinics (CG-NCG ratio: 0.96 [95% CI: 0.93, 0.99]) and 63% between clinics (CG-NCG ratio: 0.37 [95% CI: 0.21, 0.62]). Variation in number of visits decreased by 7% within clinics (CG-NCG ratio: 0.93 [95% CI: 0.90, 0.96]) and 19% between clinics (CG-NCG ratio: 0.81 [95% CI: 0.39, 1.49]).

CONCLUSION: Implementing a care guideline for TKA rehabilitation may improve outcomes and reduce unwarranted variation in practice within clinics and especially between clinics within a large health care system.

Published: December 2022

3-Ketosteroid Δ1-dehydrogenases (KstD) are important microbial flavin enzymes that initiate the metabolism of steroid ring A and find application in the synthesis of steroid drugs. We present a structure of the KstD from Sterolibacterium denitrificans (AcmB), which contains a previously uncharacterized putative membrane-associated domain and extended proton-relay system. The experimental and theoretical studies show that the steroid 1-dehydrogenation proceeds according to the Ping-Pong bi-bi kinetics and a two-step base-assisted elimination (E2cB) mechanism. The mechanism is validated by evaluating the experimental and theoretical kinetic isotope effect for deuterium substituted substrates. The role of the active site residues is quantitatively assessed by point mutations, experimental activity assays, and QM/MM MD modelling of the reductive half-reaction (RHR). The pre-steady-state kinetics also reveals that the low pH (6.5) optimum of AcmB is dictated by the oxidative half-reaction (OHR), while the RHR exhibits a slight optimum at the pH usual for the KstD family of 8.5. The modelling confirms the origin of the enantioselectivity of C2-H activation and substrate specificity for Δ4-3-ketosteroids. Finally, the cholest-4-en-3-one turns out to be the best substrate of AcmB in terms of ΔG of binding and predicted rate of dehydrogenation.
Supramolecular chemistry of two new bis(1,2,3-triazolyl)pyridine macrocycles: metal complexation, self–assembly and anion binding
Authors: David Arthur , Goodwin Rosemary , White Nicholas
Published: December 2022

Two new macrocycles containing the bis(1,2,3-triazolyl)pyridine (btp) motif were prepared in high yields from a btp diazide precursor (1). Solution 1H NMR studies show that this diazide undergoes self–assembly with divalent transition metal ions to form ML2 complexes with pendant azide groups, apparently suitable for conversion into metal-templated catenanes; however attempts to form these catenanes were unsuccessful. Instead a new macrocycle containing two btp motifs was prepared, which forms a nanotube structure in the solid state. Reduction of the azide groups to amines followed by amide bond formation was used to convert 1 into macrocycle 8 containing btp and isophthalamide functionalities. This macrocycle binds halide and oxalate anions in acetonitrile solely through the isophthalamide motif, and binds aromatic dicarboxylates very strongly through both the isophthalamide amide donors and the btp triazole donors. The macrocycle was complexed with Pd(II) and the resulting complexes were shown to bind strongly to halide anions. The solid state structures of these [Pd·8·X]BF4 (X = Cl–, Br–, I–) were investigated by X-ray crystallography, which showed that [Pd·8·Br] forms an unusual “chain of dimers” structure assembled by metal complexation, N–H···Br– hydrogen bonding and short Pd···Pd contacts.

Abstract

 

People travel from one region to another is carried out for various reasons, with one of which is to meet economic needs. The availability of transportation services, including land transportation, affects the mobility of people who make these trips. Opportunities to work that provide better income are an important factor for someone to migrate, especially for groups of people of productive age. The purpose of this study is to identify labor mobility patterns. The results obtained can enrich knowledge about labor mobility in Indonesia. This study shows that roundtrip mobility and circular mobility are the travel patterns that are mostly chosen by workers in metropolitan areas, using road and rail transportation modes. Roundtrip mobility and circular mobility always grow significantly every year, even though during the Covid-19 pandemic they experienced a decline.

Abstract

 

South Kalimantan is one of the largest coal exporters in Indonesia, which every year experiences an increase in demand. Good business strategy planning needs to be a concern for coal mining business owners, so that production targets can be met. This study aims to be able to provide recommendations for travel scenarios for coal hauling trucks in South Kalimantan. These recommendations are designed by considering the results of the analysis of travel time and truck speed for each coal transportation activity, which is obtained from the implementation of a fleet management system using a Smart GPS Tracker tool mounted on a transport truck. This study shows that the total duration of one cycle of coal hauling trip, which is currently around 6 hours, can be shortened by around 35%, which means that coal hauling productivity can be increased.

Ekologi Integral: Alternatif dalam Krisis Lingkungan Hidup
Authors: Haward Ambrosius S.
Published: December 2022

Today’s ecological crisis is getting worse, and human activities might have been the main cause of the crisis. From a theological point of view, the spiritual crisis among the modern people can be thought of as the source of the devastating human activities. Pope Francis in his encyclical Laudato Si’ believes that mistaken anthropocentrism and technocratic paradigm are the main cause, while theologian Leonardo Boff points on the modern science experimental perspective and the attitude of negligence as the triggering characteristics that govern the modern people. Facing the ecological crisis which has its roots in human spiritual crisis, Pope Francis offers a model of an integral ecology, while Boff offers an eco-spirituality concept, as basis for human relation to the cosmos. Both concepts emphasise on the unity of all components that exist in the cosmos as God’s creation.
