Abstract. African mineral dust is transported many thousands of kilometres from its source regions and, because of its ability to nucleate ice, it plays a major role in cloud glaciation around the globe. The ice-nucleating activity of desert dust is influenced by its mineralogy, which varies substantially between source regions and across particle sizes. However, in models it is often assumed that the activity (expressed as active sites per unit surface area as a function of temperature) of atmospheric mineral dust is the same everywhere on the globe. Here, we find that the ice-nucleating activity of African desert dust sampled in the summertime marine boundary layer of Barbados (July and August, 2017) is substantially lower than parameterizations based on soil from specific locations in the Saharan desert or dust sedimented from dust storms. We conclude that the activity of dust in Barbados’ boundary layer is primarily defined by the low K-feldspar content of the dust, which is around 1 %. We propose that the dust we sampled in the Caribbean was from a region in West Africa (in and around the Sahel in Mauritania and Mali), which has a much lower feldspar content than other African sources across the Sahara and Sahel.

Abstract. We propose a newly developed modular MObile LIdar SENsor System (MOLISENS) to enable new applications for automotive light detection and ranging (lidar) sensors independent of a complete vehicle setup. The stand-alone, modular setup supports both monitoring of dynamic processes and mobile mapping applications based on Simultaneous Localization and Mapping (SLAM) algorithms. The main objective of MOLISENS is to exploit newly emerging perception sensor technologies developed for the automotive industry for geoscientific applications. However, MOLISENS can also be used for other appli- cation areas, such as 3D mapping of buildings or vehicle independent data collection for sensor performance assessment and sensor modeling. Compared to Terrestrial Laser Scanners (TLSs), automotive lidar sensors provide advantages in terms of size (in the order of 10 cm), weight (in the order of 1 kg or less), price (typically between 5,000 EUR and 10,000 EUR), robustness (typical protection class of IP68), frame rates (typically 10 Hz–20 Hz), and eye safety of class (typically 1). For these reasons, automotive lidar systems can provide a very useful complement to currently used TLS systems that have their strengths in range and accuracy performance. The MOLISENS hardware setup consists of a sensor unit, a data logger, and a battery pack to support stand-alone and mobile applications. The sensor unit includes the automotive lidar Ouster OS1-64 Gen1, a ublox multi-band active Global Navigation Satellite System (GNSS) with the possibility for Real-Time Kinematic (RTK), and a 9-axis Xsens Inertial Measurement Unit (IMU). Special emphasis was put on the robustness of the individual components of MOLISENS to support operations in rough field and adverse weather conditions. The sensor unit has a standard screw for easy mounting on various platforms. The current setup of MOLISENS has a horizontal field of view of 360°, a vertical field of view with 45° opening angle, a range of 120 m, a spatial resolution of a few cm, and a temporal resolution of 10 Hz–20 Hz. To evaluate the performance of MOLISENS, we present a comparison between the integrated automotive lidar Ouster OS1-64 and the state of the art TLS RIEGL VZ-6000. The mobile mapping application of MOLISENS has been tested under various conditions and results are shown from two surveys in the Lurgrotte cave system in Austria and a glacier cave in Longyearbreen on Svalbard.

Published: February 2022

Abstract. Global sustainable agricultural systems are under threat, due to projected increases of co-occurring drought and salinity with climate change. Combined effects of drought and salinity on agricultural crops have traditionally been evaluated in small-scale experimental studies. As such the need exists for large scale studies that increase our understanding and assessment of the combined impacts in agricultural practice in real life scenarios. This study aims to provide a new approach to estimate and compare the impacts of drought, salinity and their combination on crop traits at large spatial (138.74 km2) and temporal extents in the Netherlands using remote sensing observations. Specifically, for both maize and potato, we calculated five functional traits from Sentinel-2 observations, namely: leaf area index (LAI), the fraction of absorbed photosynthetically active radiation (FAPAR), the fraction of vegetation cover (FVC), leaf chlorophyll content (Cab) and leaf water content (Cw). Individual and combined effects of the stresses on the seasonal dynamics in crop traits were determined using both one-way and two-way ANOVAs. We found that both stresses (individual and co-occurring) affected the functional traits of both crops significantly (with R2 ranging from 0.326 to 0.796), though with stronger sensitivities to drought than to salinity. While we found exacerbating effects within co-occurrent stresses, the impact-level depended strongly on the moment in the growing season. For both crops, LAI, FAPAR and FVC dropped the most under severe drought stress conditions. The patterns for Cab and Cw were more inhibited by co-occurring drought and salinity. Consequently, our study constitutes a way towards evaluating drought and salinity impacts in agriculture with the possibility of potential large-scale application for a sustainable food security.

Published: February 2022

Abstract. Climate change impact on avalanches is ambiguous. Fewer, wetter, and smaller avalanches are expected in areas where snow cover is declining, while in higher altitude areas where snowfall prevails, snow avalanches are frequently and spontaneously triggered. In the present paper, we assess 39 years (winters of 1979–1999 to 2002–2020) of avalanche activity related to meteorological and snow drivers in the Krkonoše Mountains, Czechia, Central Europe. The analysis is based on an avalanche occurrence dataset for mostly south, south-easterly oriented 60 avalanche paths and related meteorological and snowpack data. Since 1979, 179/531 wet-snow/slab avalanches have been recorded. The aim is to analyze changes in avalanche activity: frequency and magnitude, and detect driving weather variables of wet and slab avalanches with quantification of variable importance. Especially, the number of wet avalanches in February and March has increased in the last three decades, while the number of slab avalanches has decreased with decadal variability. Medium, large, and very large slab avalanches seem to decline with decadal variability since 1961. The results indicate that wet avalanches are influenced by 3-day maximum and minimum air temperature, snow depth, wind speed, wind direction, and rainfall. Slab avalanche activity is determined by snow depth, rainfall, new snow, and wind speed. Air temperature-related variables for slab avalanches were less important than rain and snow-related variables based on the balanced random forest (RF) method. Surprisingly, the RF analysis revealed less significant relationship between new snow sum and slab avalanche activity. This could be because of the wind redistributing snow in storms in low altitude mountains. Our analysis allows the use of the identified wet and slab avalanche driving variables to be included in the avalanche danger levels alerts. Although it cannot replace operational forecasting, machine learning can allow for additional insights for the decision-making process to mitigate avalanche hazard.

RANCANG BANGUN TEOLOGI MULTIKULTURAL DALAM PERSPEKTIF PERJANJIAN BARU
Authors: Sudarmanto Gunaryo
Published: February 2022

Diversitas humanitas mesti dipandang sebagai kreatifitas Allah yang patut dihargai sebagaimana Allah menghargainya sebagai gambar dan rupa-Nya sendiri. Diskriminasi humanitas justru bukti sikap antagonis terhadap otoritas penciptanya. Radikalisme doktrin yang melulu berorientasi pada kebenaran vertikal harus dibarengi dengan pemahaman horisontalnya. Kebenaran sejati justru menjadi utuh ketika kedua aspek tersebut diposisikan secara proporsional. Perbedaan bukan alasan untuk saling melawan dan menghancurkan, karena kasih kepada Tuhan dan sesama bukanlah kebenaran yang dapat dipisahkan sama sekali. Allah sendiri telah berbuat baik kepada semua orang sesuai hakikat Diri-Nya sendiri sebagai Pencipta segalanya. Allah juga menghendaki agar manusia, yang telah diciptakan dalam gambar dan rupa-Nya, saling melakukan perbuatan baik. Semua manusia memiliki tanggung jawab bersama selama kehidupannya di dunia ini, sehingga dibutuhkan solidaritas dengan sesama. Melalui interaksi yang baik justru dimungkinkan adanya point of contact bagi Injil, sehingga dapat terjadi transformasi kesadaran terhadap hakikat kebenaran Injil yang meresap ke segala aspek hidup manusia seperti garam mengasinkan dunia yang tawar (Mat 5:13). Teologi Multikultural melandasi sikap Kristen untuk berelasi dengan semua orang dalam segala bentuk perbedaannya tanpa kehilangan jati diri (keunikan) kekristenannya.

Authors: Takaliuang Morris Phillips
Published: February 2022

Sebagai suatu fenomena rohani dan teologis, gerakan pertumbuhan Gereja yang dimulai oleh beberapa hamba Tuhan, tidak dapat tidak harus diakui dan diterima sebagai jawaban Tuhan atas kebutuhan rohani Gereja Kristen dan sekaligus sebagai jawaban Tuhan terhadap kemerosotan-kemerosotan rohani dalam kehadiran dan pelayanan Gereja Tuhan terhadap dunia ini. Karena itu, disarankan supaya Gereja-gereja Tuhan masa kini, perlu masuk dan mengambil bagian yang aktif dan konkrit dalam arus pertumbuhan Gereja ini demi terlaksananya Amanat Agung Tuhan Yesus dalam Matius 28:19-20. Akhirnya, kemajuan pertumbuhan Gereja juga sangat ditentukan oleh faktor strategi Tuhan yang dapat kita pelajari dari Alkitab, khususnya kitab Kisah Papa Rasul. Di sana dijelaskan bahwa pertumbuhan Gereja mesti dimulai: (1) di tempat yang dipilih Tuhan, (2) Dilaksanakan dalam waktu Tuhan, (3) Didukung oleh hamba-hamba Tuhan yang dipersiapkan dan dibentuk Tuhan secara khusus, dan (4) Perlu diarahkan dan dibimbing oleh visi misi universal dari Tuhan sendiri. Karena itu, tulisan ini menyarankan agar Gereja-gereja masa kini sungguh-sungguh mencari dan menemukan strategi Tuhan yang khusus untuk tiap-tiap pelayanan misi yang kita kerjakan.
KONTRIBUSI GAGASAN JÜRGEN HABERMAS BAGI HERMENEUTIKA POSTMODERN
Authors: Efruan Erni M.C.
Published: February 2022

Pertama, konteks sosial postmodern terdiri dari banyak bagian dan berubah-ubah, yang memengaruhi hermeneutika seseorang. Hermeneut menjadi titik tolak hermeneutika, dan ini menyebabkan hermeneutika menjadi penting. Karenanya, bila hermeneut meninggalkan makna teks dan maksud penulis, maka ia akan tenggelam dalam lautan relativitas postmodern, dan tak ada dimensi metanaratif yang absolut. Kedua, pewahyuan ilahi itu sendiri terkondisi secara budaya karena  dikomunikasikan kepada berbagai budaya dalam berbagai bahasa yang tidaklah netral dan tak dapat dihapuskan oleh postmodern. Ketiga, teologi kritis bisa memberi kemungkinan mengerjakan refleksi-diri terus-menerus. Kritis atas kenyataan dunia harus dibarengi dengan kritik terhadap diri sendiri. Untuk itu diperlukan sebuah pola hermeneutik yang kritis atas teks-teks mapan yang ada. Keempat, jika hendak menginterpretasi secara benar dan tepat, maka kita harus mengupayakan dialog antara bahasa dan pengalaman di satu sisi dengan tindakan di sisi lain. Tidak memisahkan teori dan praksis, tidak melepaskan fakta dari nilai semata-mata untuk mendapat hasil yang objektif. Kelima, bahasa mencakup seluruh makna dan oleh sebab itu hermeneutika memiliki implikasi yang universal. Pentingnya sosiologi pengetahuan sebagai suatu sarana penafsiran. Keenam, kekuatan-kekuatan ideologis mengendalikan hermeneutika hampir semua orang. Calvinis atau Armenian, Reformed atau Dispensasional, Teolog Proses atau Pembebasan, tiap komunitas orang percaya telah memberikan kecenderungan-kecenderungan ideologis tertentu yang menuntun penafsiran. Karenanya, hermeneutika harus membebaskan pemahaman dari ideologi. Ketujuh, pemahaman hermeneutik sifatnya global, yaitu mengandaikan adanya tujuan khusus. Setiap komunikasi yang sehat adalah komunikasi dimana setiap partisipan bebas untuk menentang klaim-klaim tanpa ketakutan akan koersi, intimidasi, deceit dan sebagainya. Melalui tindakan komunikatif, pemahaman hermeneutik mempunyai bentuk yang hidup, yaitu kehidupan sosial Postmodern.

Authors: Tanoto Suma Pratiwi , Mery Giovani Gusti Ayu Vina
Published: February 2022

Introduction: Basal cell carcinoma (BCC) is a malignancy which often affects white-skinned people. The incidence increased in the world up to 10% per year. Ultraviolet exposure is the most common risk factor, and usually affects head and neck. Patients with BCC have increased risks of having melanoma but no other internal malignancy. The existence of lumps which easily bleed and hard to heal perfectly is the most common symptoms found. Diagnosing it is based on the description of the lesion and the result if skin’s histopathology examination. Management is a very important aspect because if it is not treated, it will invade the surrounding tissue and result in functional and cosmetic disturbance.
Objective: To describe the clinical relevance regarding symptom, dermoscopy examination and treatment of basal cell carcinoma.
Case Report: A 48-year-old male complained of having a wound on his left shoulder since a year before. At the beginning the lesion was small and red, then gradually grew larger and black. Patient did not admit having the same complaint before and there was no history of disease or malignancy. He also done dermoscopy examination which is the result led to basal cell carcinoma characteristics. Excision wound on his left shoulder was done and the histopathology result came as a mixed type basal cell carcinoma.
Discussion: Based on anamnesis, physical and diagnostic examinations, the working diagnosis of this patient was mixed type basal cell carcinoma. Diagnostic test is carried out by dermoscopy and histopathology examination. From the dermoscopy examination, it was found that the result was consistent with the characteristic of basal cell carcinoma. The histopathology result also confirmed that the cells were matched with the description of basaloid cells arranged palisades at the edge. The skin’s condition had to be evaluated in the next six months.
Conclusion: Basal cell carcinoma is a common malignancy which happens most often in white-skinned people who are exposed to ultraviolet regularly. It is very important to check skin’s condition if a suspicious lump is present. The management is a crucial aspect needed to prevent invasions to surrounding tissues.

MSME sector forms the backbone of economic progress and development of any State because of its contribution to industrial productivity, employment generation, versatile nature, adaptability and contribution in exports. MSME industries constitute an important segment of the Uttar Pradesh?s economy. The state has highest number of MSME?s which is around 89 lakh MSME and is equivalent to 14% of the total MSMEs in India. With such huge involvement of MSMEs in UP?s economy raises a question that what is the performance and contribution of this sector to UP. Based on this question the present study aims in evaluating the role of MSME?s in overall development of UP?s economy through employment generation, and contribution to production, exports etc. It aims to analyse the extent of relationship between the growth of investment and number of units of MSME on its impact in the development of UP through calculation of correlation coefficients and testing its significance level. Several ratios and growth rates have been calculated and used as research tool to observe and analyse the impact of growth in this sector. Ratio and trend analysis approach have been adopted. The study follows empirical and descriptive research design. Analysis of data from Annual reports of MSME?s and various relevant sources for 2000-2020 shows that MSMES?s have pointed out certain shocking results that though there is growth in the MSME sector of UP, the production has increased at a decreasing rate. Employment has also shown the same results which clearly reflects that even though the UP accounts for maximum MSMEs and still counting but the real development which is predicted through quality and not quantity reveals a different picture.

Authors: Omelchenko Liliіa V.
Published: February 2022

The relevance of the study lies in the fact that intense social changes are transforming not only society, but also affect the main reference points in education, which prompts the teaching community to consider current trends in the development of the European school. The purpose of the study is to generalize and systematize scientific, methodological, pedagogical and psychological aspects of the learning process and the development of key skills of students through the use of didactic capabilities of media education technologies. The theoretical and methodological basis of the research consists of methodologies of the following approaches: didactic, general scientific, comparative. In the process of research it was determined that in a changing environment, only individuals who are able to adapt to constant rapid change, solve complex problems, think critically about the circumstances, compare alternative points of view and make balanced decisions can navigate and act actively. It is confirmed that the main goal of modern education is not to provide students with important information, but to develop a critical view of the perception and research of information. Media education technologies were found to help prepare an applicant of education for life in an information society, choose the main thing among the incessant flow of information, critically examine the information received, and cooperate with others. In scientific research, media education is considered as one of the tools that helps teachers replace passive listening of a student or primitive retelling with active participation in the educational process, and thereby increase the effectiveness of classes. The introduction of media-educational technologies in practice was proved to solve this issue by applying strategies for the development of critical and systematic thinking. The practical significance lies in the implementation and systematization of critical thinking mechanisms as a tool for introducing media education technology for the development of key skills of students
Work with Children at Risk in a Modern Educational Space
Authors: Mykhed Inna V.
Published: February 2022

The relevance of studying the methods of working with children at risk is extremely high, both for ordinary teachers and school psychologists. The number of children at risk is constantly growing, resulting in the need to analyse the mechanism of their upbringing within educational institutions. In addition, consideration of this issue is extremely important for society, because by choosing the right approach of the teacher to such students, there is an opportunity to re-educate them and build their respect for the norms of society and promote their personality as a law-abiding citizen. Thus, the purpose of the study is to analyse the theoretical concept of risk group, to establish its features, to investigate the criteria by which students get to them, and to consider current methodological measures for organising educational work with such children and compare them with modern educa-tional space. To achieve this goal, a set of methods was used, including both general and pedagogi-cal, namely: logical analysis, synthesis, comparative analysis, deduction, pedagogical observation, morphological method, and analysis scientific literature. The results obtained during the study can be divided into two components, namely theoretical and practical. According to the first, it is necessary to establish the essence of the concept of children at risk, to reveal its features and factors that affect it. The practical component is the analysis of current tools and approaches used in working with stu-dents at risk, including establishing their effectiveness and determining the appropriateness of their use in modern educational space and, accordingly, making recommendations for their improvement. The practical significance of the study lies in the fact that, when teachers or social psychologists use the methods developed in it, the process of changing students' attitudes and consolidating in them the values that will help them to become full members of society who will respect the rights and freedoms of other citizens and, accordingly, the social norms that have been established
Analysis of the Dynamics of Foreign Currency Exchange Rates in Ukraine Including Seasonality Factors and Demand for Domestic Government Loans Bonds (Over 5-10 Years)
Authors: Roshylo Violetta I. , Long Samuel
Published: February 2022

The relevance of the scientific article lies in the need to substantiate the importance of the role of currency exchange rates for the robust functioning of the country’s economy. The purpose of the article is to analyse the dynamics of foreign currency exchange rates, mainly the dollar, and the euro, in Ukraine, taking into account factors of seasonality and demand for government bonds. The main methods used in the paper are statistical empirical research methods, in particular modelling. It was determined that the export of raw materials, mainly steel, and various agricultural crops such as wheat, corn, sunflower oil, soybeans, etc., plays a particularly important role in Ukraine. It was found out that the mentioned fluctuations in export are one of the reasons for the currency seasonality, but not the only one or the main reason, as the exchange rate is strongly influenced by oil, gas, and other energy resources prices, which the country needs constantly, especially during the heating season. The exchange rate of the hryvnia over the last five years within the context of the National Bank of Ukraine has also been analysed. It was found that the demand for government loans bonds is one of the most important factors in considering the foreign currencies exchange rates in Ukraine. To make models more plausible and to reduce the influence of other factors in determining seasonality of the currency with certain currency pairs with the dollar, euro, yen, zloty, and ruble, the data for the last several years has been used, which are less likely to be distorted by the influence of external factors. It has been confirmed that a successful trade policy is a key source of currency stabilisation in Ukraine. The article is useful for studying the functioning of currencies in general; for studying the economy of Ukraine, especially the country’s currency issues; for students of various economic disciplines
Attitude Towards Farming and the Dependency Associated with Access to Social Grants: The Case of Ngqele Village, Nkonkobe Municipality, Eastern Cape
Authors: R. Freddy , M. Abbyssinia
Published: February 2022

Using data drawn from a sample of 50 households in Ngqele village, the paper investigated households’ attitude towards farming as a livelihood source and the possibilities of the dependency syndrome associated with access to social grants. Descriptive statistics were used to analyse the data and a 5 point Likert scale was used to determine households’ attitudes towards farming as a livelihood source. The results confirmed overdependence on state grants which is hindering livelihood improvement. 26% of the respondents had a positive attitude towards farming. On the other hand, 38% had a negative attitude while 36% had an average attitude towards farming. The growing underutilisation of arable land in Ngqele village can be attributed to households’ ambitions and aspirations which are in favour of non-farm activities and also a relatively negative attitude towards farming. Direct and continuous support through the provision of technical and institutional support is required to sustain the level of interest in farming in this village. In addition, rural development should not only focus on land redistribution and farming but should also focus on employment creation outside the agricultural sector and the promotion of non-farm activities. Social grants should be linked to economic activities aimed at empowering households to take care of their livelihoods’ needs sustainably. Socio-economic policies that avail credit to rural households and training are also required to instil entrepreneurial skills especially to the youths in Ngqele village.

The study aimed to determine the effect of different land-use systems on soils in Yenagoa and Southern Ijaw Local Government Area of Bayelsa State. Four land use types were considered namely Fallow land, virgin land, oil palm plantation, and plantain plantation. Soil samples were randomly collected at three depths (0-15, 15-30, and 30-45cm) from three locations in the respective land-use types. The samples were bulked and prepared for the determination of some chemical properties. Core sampling was done to determine bulk density, porosity, and saturated hydraulic conductivity. A double-ring infiltrometer was used to determine the infiltration rate and cumulative infiltration. Sorptivity and transmissivity were determined from Philip’s infiltration model. The research revealed that the soils were acidic with a pH range of 4.4-4.7. There were differing levels of organic matter amongst the lands, the progression was Virgin (43.33g/kg)> oil palm plantations (34.67g/kg)> fallow land (23.33g/kg)> plantain plantations (14.67g/kg). The sand fraction dominated the various land-use systems, having loamy sand in the plantain plantation, sandy loam in the oil palm plantation and fallow land, and a range of sandy loam to sandy clay loam in the virgin land. Cumulative and infiltration rates were measured at an interval of 1, 3, and 5 minutes. The infiltration rate was slowest at the oil palm plantation (PPT) with an average cumulative infiltration of 36.3cm, and highest at the virgin land (VVL) at 67.4cm. The average cumulative infiltration of 42.2cm and 53.3cm were in the plantain plantation (OPT) and Fallow land (FFL). VVL>FFL>PPT>OPT was the progression from highest to lowest. Bulk density across the four land-use types did not exceed the critical level of 1.63g/cm3. The highest gravimetric moisture content of 25% was found in the virgin land > oil palm plantation (24%) > (fallow land) 21.6% > plantain plantation (20.3%). The virgin land had the highest sorptivity (64.5 cm/hr) while the oil palm plantation had the lowest (39.9 cm/hr) - VVL (64.5cm/hr) >FFL (55.6 cm/hr) >PPT (43.1 cm/hr) > OPT (39.9 cm/hr). Transmissivity was lowest (2.4 cm/hr) in the plantain plantation and highest (4.0cm/hr) was in the fallow land. Oil palm plantation and virgin land had transmissivity of 3.7 and 2.8cm/hr. The research showed that there were considerable impacts of land use on infiltration capacity. Soils of natural vegetations would easily support irrigation activities due to their organic matter content and should, therefore, be conserved or utilized with conservative measures, while cultivated lands should be improved regularly.

Datura metel is a plant with various medicinal parts. This work gears towards the phytochemical evaluation, identification and functional group detection of ethanolic leaf and roots extracts of Datura metel. Gas Chromatography-Mass spectrometry (GC-MS) and Fourier –Transform Infrared Spectroscopy (FTIR) analytical instruments were used for studies. The preliminary phytochemical evaluation of plant parts revealed presence of alkaloids, flavonoids, saponins, tanins and terpenes. The chromatogram result for the Gas Chromatography- Mass Spectroscopy (GC-MS), detected 30 bioactive compounds with high percentage composition and molecular weights. Thiophene, 2,3-dehydro, an isomer of dehydrothiophene (C₄H₆HS) had the least retention time and highest percentage composition of 38.914% for the root extracts while 2-methyl-3-thiosemicarbazide (C₂H₇N₃S) and Benzene hexanenitirle, dimethyl-ℇ-oxo (C₁₄H₁₇HNO) both had the highest percentage composition for the leaf extracts. The chromatogram result for Fourier –transform infrared spectroscopy (FTIR) revealed that alkenes (=C-H) and carbon tetrachloride (C-CL₄) had the highest and least wavelengths for both extracts respectively. The presence of bioactives detected and identified in this study, showed that plants may serve as reservoir for biologically active compounds and hence in addition to its medicinal values can also be used for diverse purposes in the industry.
