Identifying central negative thoughts through experience sampling and network analysis: Longitudinal Observational Study (Preprint)
Authors: Marian Stefan , Sava Florin Alin
Published: January 2023

UNSTRUCTURED

Network analysis has promised to inform clinical practice about what should be prioritised in the treatment of different psychological disorders. However, the pure phenomenological approach that network analysis has adopted didn’t help make considerable advancements towards this goal. We propose a theoretical approach based on the cognitive model of psychopathology. More specifically, we identified the most common negative thoughts in a preliminary study and then monitored them alongside symptoms of anxiety and depression in a sample of undergraduate students 3 times per day for 3 weeks. Results indicated that negative thoughts have a high bridge outdegree in the temporal network (predict the occurrence of symptoms), while symptoms have a high bridge outdegree (are predicted by thoughts). Adopting a theoretical approach has proven useful in providing concrete targets for therapy instead of just identifying central symptoms, as it is typically done in network studies. Thoughts related to self-criticism, like “There’s something wrong with me”, were the most central both for anxiety and depression and could be considered priority targets for cognitive interventions. Future network studies could also consider adopting an approach based on a psychotherapeutic theory about the aetiology of psychopathology.
REVIEW: REMOÇÃO DE PARABENOS POR PROCESSO DE OZONIZAÇÃO
Authors: Machulek Junior Amilcar , Canatto Antonio Kaique , Silva de Brito Diego Aparecido , Ribeiro Maria Lucia
Published: January 2023

A presença de parabenos e outros compostos emergentes nas águas residuárias é uma realidade que deve ser estudada e discutida por entidades físicas, jurídicas e de pesquisa na área ambiental e do saneamento, frente aos seus potenciais riscos à saúde humana e aos ecossistemas naturais.  A compreensão sobre esses novos poluentes é necessária para o desenvolvimento e aprimoramento de tecnologias de tratamento eficazes, já que os processos atuais não são capazes de remove-los. Pesquisadores de todo mundo estudam e apostam nos Processos Oxidativos Avançados (POAs), como a Ozonização, como uma dessas soluções. Como qualquer outro processo de remediação, deve-se considerar parâmetros operacionais importantes, como os efeitos do pH, doses de ozônio, tempo de reação e adição de agentes oxidantes, catalisadores e irradiação UV, tendo vista que o processo de ozonização simples apresenta baixas taxas de mineralização devido a geração de compostos orgânicos refratários à ação do ozônio, os quais serão tema desse estudo.

Debido a su bajo costo y amplio uso, los plásticos son hoy en día un consumible ineludible. Los efectos de los microplásticos en el medio ambiente es un campo de investigación reciente en Argentina. Durante el invierno y la primavera de 2019 se gestionaron dos campañas de estudio de presencia de microplásticos en sedimentos costeros del Rìo de la Plata: se seleccionaron playas de la Capital Federal y alrededores (AMBA), los sedimentos se muestrearon y caracterizaron. Se confirmó, clasificó y caracterizó la presencia de microplásticos según su morfología y color. Los microplásticos se separaron mediante técnicas de flotación y se identificaron visualmente mediante observación microscópica. La campaña de invierno reportó más ítems de microplástico (un total de 464 sobre los 280 de la campaña de primavera), siendo las fibras y microesferas las más representativas. Si bien este es un trabajo preliminar, los microplásticos encontrados son consistentes con las actividades económicas del área de estudio y la dinámica hidrogeológica de la cuenca del Río de la Plata. El monitoreo debe continuar para elaborar una línea de base ambiental, dilucidar el origen y el destino de los microplásticos e implementar acciones de control.

Authors: Frota Renata Locarno Frota , Silva Samiria Maria Oliveira , Araújo Junior Luiz Martins , Ribeiro Francisco Wellington
Published: January 2023

Economic instruments, such as water charges, have been used to promote water conservation and raise funds for basin management. However, there is a need to improve the water collection model in Brazil. The aims of this study were to analyze the evolution of raw water charges in the State of Ceará and verify the effect of drought on the costs and water collection from 2011 to 2019 to answer two questions: does the water collection fulfill its function of financing the water resources system? Is the pricing model flexible to absorb the effects of climate variability? We conducted a content analysis to determine the presence of certain words in selected documents, and then analyzed the costs of system operation. The results show that the payment capacity is lower than the tariff applied to water. The Status Index is negatively correlated with the Administration (ADM) and Operation and Maintenance (O&M) costs. The generated revenue is mainly used to cover the management costs (ADM and O&M); however, it is insufficient to finance the implementation of measures, programs, and projects to improve the water management in respective basins. Thus, a floating tariff should be established in which the water scarcity and effects of climate variability are incorporated.

Forgiveness and Grief Symptoms in Women After Perinatal Loss
Authors: Lākute Inta , Upmane Anda
Published: January 2023

The purpose of this research was to explore the relationship between aspects of forgiveness, grief symptoms and bereavement in women after perinatal loss. In addition, to explore to what extent forgiveness and bereavement aspects predict grief symptoms. Participating in the study were 440 women, aged between 20 to 45 years, (M = 33,2). They completed the Heartland Forgiveness scale (Thompson & Snyder, 2003), adapted by Vendija Balode (Balode, 2017) and the Traumatic Grief Inventory (Self-Report Version, Boelen, & Smid, 2017), which was adapted as a part of this study. The results of research showed that there were negative relationships between forgiveness and grief symptoms. Bereavement aspects, such as the severity of the perceived bereavement, experienced bonding with the lost baby, and the time since the loss were positive predictors of grief symptom, whereas forgiveness in general, having received psychological assistance and overcoming the perceived loss, were negative predictors of the symptoms of grief.

Published: January 2023

The aim of this study was to examine reported changes in children’s behaviour after the children, parents and teachers had participated in the modified early intervention program “STOP 4–7”, which has been developed for children 4 to 7 years old. The aim was also to examine if there are changes in the parents’ parenting behaviour, and if there are differences in the degree of behavioural change ratings between the original and modified “STOP 4–7” groups. For purposes of this study 31 children participated in the first group and 48 children in the second group, as well as at least one of the child’s parents and their teacher. Before and after participation in the program, one of the child’s parents and their teacher completed questionnaires about the child’s behaviour. Parents also completed the Ghent Parental Behaviour Scale. Results show that after participation in the program, in both groups there was a decrease in the child’s externalizing behaviour problems, according to both the parents’ and teachers’ report. After participation in the modified program there was an increase in the parents’ report of discipline strategies and material reward ratings.
Profiles of cognitive ability domains in children with and without ADHD symptoms
Authors: Skara Dana , Vanags Edmunds
Published: January 2023

Studies to date have most often compared the mean scores of an ADHD and control group to see if there are differences between them. Various cluster or linear data processing methods have also been used in studies to group children into certain subgroups according to various characteristics, but so far we have not found any study that has succeeded in dividing both ADHD and control group children into such subgroups. Results vary from study to study. Therefore, the aim of this study was to investigate and compare the heterogeneity of different cognitive ability domains in children with and without ADHD symptoms with qualitative data analysis methods - creating unique profiles of cognitive ability domains for each child. In this study participated 76 children aged 8–13 and were divided into two groups: ADHD group – 46 children (M = 10.08; SD = 1.67), control group – 30 children (M = 9.41; SD = 1.60). Four methods were used to calculate cognitive ability domain scores: Stroop’s Word and Color Test, Symbol Digit Modalities Test, Digit Span Test, and Continuous Performance Test. The analysis of the profiles revealed a wide heterogeneity in both groups. Also, it was observed in these profiles that children with ADHD experience had more pronounced difficulties in cognitive ability domains compared to the control group. At the same time, it can be concluded that not all children with ADHD experience them. Comparing profiles of children from either of these two groups it can be concluded that some of the children with ADHD symptoms have profiles similar to typically developing children.
Corporate Social Responsibility Reporting as an Important Communication Tool: Some Evidence from Latvia
Authors: Medne Ilze , Ņikadimovs Oļegs
Published: January 2023

The relevance and importance of Corporate Social Responsibility (CSR) have long been recognised in the business sector. Firms, communities, and individuals must shift their perspectives on CSR from voluntary actions to almost obligatory initiatives, especially in terms of corporate communications. This study aims to review the corporate sustainability framework from the perspective of CSR reporting and communication with some evidence from Latvia. The study has used secondary qualitative research methods, reviewing previously published scholarly literature and studies on the selected topic. Environmental impact and measures, society benefits and economic gains are the most important parts of CSR reporting, internal and external communication. In light of the recently experienced environmental, societal and economic challenges, this study advocates concentrating on CSR reporting and increased inquiry into the role of building efficient communication with relevant stakeholder groups – selecting the right channels, frameworks and report verification tools, to improve transparency and credibility. Researchers and practitioners must consider the role of CSR communication in a broader context, given the difficulties connected with economic, environmental and societal challenges, as good communication is critical for mobilisation and deciding on goals through consensus.
Latvian-Lithuanian Economic Relations 1918–1940
Authors: Karnups Viesturs Pauls
Published: January 2023

This paper provides an overview of Latvian-Lithuanian economic relations in the interwar period. In the interwar period, economic relations between Latvia and Lithuania were mainly confined to foreign trade, although there were some investments in Latvia from Lithuania, as well as tourism. Latvia’s foreign trade in relation to Lithuania was regulated by a number of trade treaties and agreements entered into in 1930, 1933, 1935, and 1936. Latvia’s main imports from Lithuania in the interwar period were horses, seed flax, cattle, pigs and piglets, and timber and timber products, whilst Latvia’s main exports to Lithuania were coal, machinery (agricultural and industrial), paper, timber and timber products, rubber goods (including galoshes), cement, as well as radios. In general, trade and thus economic relations were of marginal significance to both countries in the interwar period due mainly to similarities in their agriculturally based economic structures.

Authors: Sloka Biruta , Angena Anna
Published: January 2023

Health self-evaluations are aspects analysed by researchers world-wide as from self-evaluation depend many aspects of person’s feelings, satisfaction with life and motivation for active life. Researchers have identified that often health self-evaluation is better than reality and the person achieves many goals in their life even with not so good health, and there are many cases when the health self-evaluation is good, but reality is much worse. Comparative data analysis on health self-evaluations in EU countries, EEA countries and EU candidate countries are carried out in EU-SILC. The aim of this article is to investigate – do health self-evaluations differ statistically significant by inhabitants of Latvia in urban areas and in rural areas. Research methods applied: scientific publications analysis, analysis of data obtained in EU-SILC survey using different statistical indicators: indicators of descriptive statistics, cross-tabulations, statistical hypotheses test with t-test on equalities of arithmetic means. Results indicate that although the health self-assessment by inhabitants are higher in rural areas in Latvia in comparison with urban health self-assessment by inhabitants, the difference on averages of those evaluations is not statistically different with significance level 0.001.

Forbidden Love, Meat and Cannibalism: An Analysis of Bhaskar Hazarika's Aamis (Ravening)
Authors: Sarmah Riswita
Published: January 2023

Abstract The paper attempts to explore Aamis (Ravening) (2019), an Assamese film from India, written and directed by Bhaskar Hazarika. The film chronicles a story of passion between Nirmali, a married woman and Sumon, a young researcher. Sumon, a meat connoisseur, studying the meat eating habits of different communities serve as a metafictional strategy of the film. Meat becomes a mode of showcasing liminality and the body politic. The two create a carnivalesque world for themselves, where meat becomes a medium of expressing their unprofessed desire. With the turn of events Sumon makes Nirmali taste his own flesh, camouflaging it as an exotic meat. Resulting in Nirmali's extreme yearning for human flesh. Nirmali undergoes a process of 'unfinalizability', revealing a side to herself that she had never known. Aamis through its surrealistic portrayal of cannibalism brings forth the grotesque and the macabre. Nirmali's desire for human meat turns her into a monstrous 'other'. Sumon and Nirmali become figures of 'homo-sacer', beyond the control of the state. In the conclusive scene, for the first time Nirmali touches Sumon, in public with faces covered by cloth. The markers of identity become ineffectual by then. Almost indifferent to the world around them, they stand as lovers hand in hand who had tasted, that which is "forbidden".

Published: January 2023

Introducción: el VIH/sida sigue siendo un problema de salud pública a pesar de ser una enfermedad prevenible. La comprensión de los años de vida saludables perdidos a causa de esta enfermedad es importante. Objetivo: determinar la carga de la enfermedad por VIH/sida en la Orinoquia colombiana, 2010-2018. Materiales y métodos: estudio descriptivo, longitudinal retrospectivo en las personas con diagnóstico de VIH y en las fallecidas por VIH/sida de los departamentos de la Orinoquia colombiana entre 2010 y 2018, reportadas en la Aplicación Nacimientos y Defunciones - RUAF y al registro individual de prestación de servicios (RIPS). Para el análisis se usó la estimación de pérdida de años de vida saludable (AVISA), constituida por los años de vida vividos con discapacidad (AVD) y los años perdidos por muerte prematura (AVMP). Resultados: se reportaron 12.026 personas con diagnóstico de VIH/sida y 840 fallecimientos por sida. Los hombres representan la mayor proporción de la morbilidad (rango 50 %-64 %) y la mortalidad (71,3 %), la edad de ocurrencia se concentra entre los 25-44 años en morbilidad y 25-39 años para mortalidad. Se perdieron 51.290 AVISA especialmente por muertes prematuras (87 %) en hombres (35.736), en el grupo de edad entre 25-39 años. Por cada AVISA perdido por las mujeres, los hombres pierden 2,3. Conclusión: los años vividos con un estado de salud subóptima en personas con VIH/sida en la región han venido incrementando por causa del mayor tiempo de supervivencia ya demostrado en la disminución de los AVMP, especialmente en los hombres debido a su mayor incidencia.

Authors: Triwardhani Diana , Yuliniar  , Aswar Khoirul , Supriyadi Yudhi Nur
Published: January 2023

This study intends to ascertain and assess how Starbucks coffee customers' perceptions of the halal label, lifestyle, and service quality affect their purchasing decisions. Given that the majority of people in Indonesia are Muslims and that buying a product with a halal label necessitates considering that, as well as the fact that the subject product comes from a non-Muslim nation, this study was conducted. Data were collected from a sample of 252 persons on the island of Java using a questionnaire, and the data were then analyzed using PLS. The results show that the perception of halal labeling, lifestyle and service quality has an impact on purchase decisions. This indicates that the sample used in the study will consume or purchase Starbucks goods if they are halal in compliance with the halal label on the product. Additionally, Starbucks customers tend to be individuals who lead an active lifestyle. Some customers of Starbucks are accustomed to receiving high-quality service along with their purchases; if this trend continues, the sample that will be used in this study won't purchase Starbucks goods.
Canned meat products for members of the Serbian armed forces: Na, K, Ca, and Mg content and health risks/benefits
Authors: Stojanovic Branislav , Stojanovic Zdenka , Marjanovic Sonja , Jankovic Sasa , Antic Malisa , Balaban Milica , Antic Vesna
Published: January 2023

Macroelements such as Na, K, Ca, and Mg play a significant physiological
role, and their inadequate intake has been linked to severe diseases, such
as high blood pressure. Data on risk assessment for human health in Serbia,
from the intake of these macroelements through the consumption of canned
food, are minimal. Therefore, the content of Na, K, Ca, and Mg in five types
of canned meat that members of the Serbian Armed Forces regularly use was
examined. Macroelements were determined by inductively coupled plasma mass
spectrometry in cans of beef goulash, pork ragout, spam, liver pate, and
meatballs in tomato sauce, which were stored from one month to six years.
The sodium content was significantly higher than the potassium content in
all types of food, so the Na/K ratio below 1, desirable for good health, was
not found in any of the analyzed products. Also, a significant number of
samples had an unfavorable Ca/Mg ratio above 1. However, due to the low
consumption of canned food by members of the Serbian Armed Forces, its
contribution to the average daily intake of macroelements is almost
negligible. The concentration of macroelements decreased with the shelf
life, while a significant source of Ka and Mg, among analyzed ingredients,
was ground red pepper.

Authors: Baskakov A. A. , Tarasov A. G.
Published: January 2023

Introduction. To develop new system modules of software to help employees with disabilities, it is required to work out an architectural solution for the interaction of all parts of the system. As a result of the analysis and design, it is necessary to obtain a software architecture that must meet a number of standard requirements. First of all, it should be safe. To do this, you should take into account the error logging system, event auditing, the possibility of disabling the functionality immediately after putting it into commercial operation, internal mechanisms for validating client input requests and server responses. This study is aimed at the development of basic system maintenance options, the analysis of exception cases under interacting with the user for further evaluation of the architecture efficiency, and the direct project development.   Materials and Methods. The architectural decision was carried out using the Unified Modeling Language (UML), which helps to build visual images of the life cycle and interaction of all components of the system. The syntax of the UML deployment diagram was used to study the interaction of the main modules of the future system, and the syntax of the UML sequence diagram was used to process the lifecycle. A use case diagram was also applied to describe the main use cases. To study the interaction of the main modules of the future system, the UML deployment diagram syntax was used. For life cycle processing, the UML sequence diagram syntax was applied. In addition, a use case diagram was applied to describe the base use cases.   Results. An architecture that has a scheme for the interaction of individual modules and systems, as well as options for using the software package for the future implementation of the software product, has been developed. The proposed system architecture meets the requirements of security, reliability (fault tolerance), and performance. The authors have fixed the functional requirements of the system of assistance to employees of enterprises with hearing problems for the possibility of their employment and work on the telecommunication Internet. Basic variations of system maintenance have been developed.   Discussion and Conclusions. Building a competent architecture provides taking into account cases that go beyond the normal use of the system, and applying a fuzzy model to determine the system efficiency. Further in-depth description of deployment and operation options will enable to implement an efficient and productive system.

Authors: Ronaldo Febby , Sudarsono Amang , Pramadihanto Dadet
Published: January 2023

Drone technology is considered the most effective solution for the improvement of various industrial fields. As a delivery service, drones need a secure communication system that is also able to manage all of the information data in real-time.  However, because the data transmission process occurs in a wireless network, data will be sent over a channel that is more unstable and vulnerable to attack. Thus, this research, purposes a  Forward Prediction Scheduling-based Stream Control Transmission Protocol (FPS-SCTP) scheme that is implemented on drone data transmission system. This scheme supports piggybacking, multi-streaming, and Late Messages Filter (LMF) which will improve the real-time transmission process in IEEE 802.11 wireless network. Meanwhile, on the cybersecurity aspect, this scheme provides the embedded option feature to enable the encryption mechanism using AES and the digital signatures mechanism using ECDSA. The results show that the FPS-SCTP scheme has better network performance than the default SCTP, and provides full security services with low computation time. This research contributes to providing a communication protocol scheme that is suitable for use on the internet of drones’ environment, both in real-time and reliable security levels.

In order to achieve crack free elliptical shape under controlled conditions, an experimental set-up was designed and fabricated. This setup consists of three hydraulic cylinders, an intensifier, a hydraulic power pack, storage tanks, forming die, and all parts are controlled by a Programmable Logic Controller (PLC) system. The elliptical samples can be achieved through proper control of internal pressure and axial force with proper sealing. Experimental work has been carried out with different magnitudes of internal pressure and constrained conditions of axial force. Initially die of elliptical shape has been designed and modeled in Abaqus to successfully achieve the particular shape of the Al6061T4 tube under different internal pressure. The fabricated tube hydroforming machine set-up is highly effective for forming 0.5 mm-2 mm thick Al6061T4 alloy tube samples. The Experimental test has been carried out at 12.7 mm outer diameter, 175 mm length and 0.5 mm thick Al6061T4 samples. Bulge height parameters measured at different points of regular distance gap on the axial direction of the tube length and corner radius found at different pressures range of the samples are plotted under different internal pressures. Samples having an 18.7 mm major elliptical bulge were achieved during the experiment. The experimental data was validated by simulation results.

Authors: Idris Muhammad , Syarif Iwan , Winarno Idris
Published: January 2023

The trend of API-based systems in web applications in the last few years keeps steadily growing. API allows web applications to interact with external systems to enable business-to-business or system-to-system integration which leads to multiple application innovations.  However, this trend also comes with a different surface of security problems that can harm not only web applications, but also mobile and IoT applications.  This research proposed a web application security education platform which is focused on the OWASP API security project. This platform provides different security risks such as excessive data exposure, lack of resources and rate-limiting, mass assignment, and improper asset management which cannot be found in monolithic security learning application like DVWA, WebGoat, and Multillidae II. The development also applies several methodologies such as Capture-The-Flag (CTF) learning model, vulnerability assessment, and container virtualization. Based on our experiment, we are successfully providing 10 API vulnerability challenges to the platform with 3 different levels of severity risk rating which can be exploited using tools like Burp Suite, SQLMap, and JWTCat.  In the end, based on our performance experiment, all of the containers on the platform can be deployed in approximately 16 seconds with minimum storage resource and able to serve up to 1000 concurrent users with the average throughput of 50.58 requests per second, 96.35% successful requests, and 15.94s response time.

Published: January 2023

In human-robot interaction, human mental states in dialogue have attracted attention to human-friendly robots that support educational use. Although estimating mental states using speech and visual information has been conducted, it is still challenging to estimate mental states more precisely in the educational scene. In this paper, we proposed a method to estimate human mental state based on participants’ eye gaze and head movement information. Estimated participants’ confidence levels in their answers to the miscellaneous knowledge question as a human mental state. The participants’ non-verbal information, such as eye gaze and head movements during dialog with a robot, were collected in our experiment using an eye-tracking device. Then we collect participants’ confidence levels and analyze the relationship between human mental state and non-verbal information. Furthermore, we also applied a machine learning technique to estimate participants’ confidence levels from extracted features of gaze and head movement information. As a result, the performance of a machine learning technique using gaze and head movements information achieved over 80 % accuracy in estimating confidence levels. Our research provides insight into developing a human-friendly robot considering human mental states in the dialogue.
Spatio-Temporal Water Quality Assessment and Pollution Source Apportionment of Lake Chamo using Water Quality Index and Multivariate Statistical Techniques
Authors: Ghebremedhin Solomon Ghebrehiwet , Gupta Bhaskar Sen
Published: January 2023

Despite the current management effort to reduce pollution of water bodies, lakes are far more vulnerable to pollution than the ocean and rivers. Point and non-point pollution are ending on the lake bodies and concerned bodies should trigger interventions. This study aims to assess the effect of pollution on the water quality of Chamo lake using the weighted arithmetic water quality index (WQI) and multivariate statistical methods. Fifteen monitoring points are used to collect water samples from the lake for dry and rainy periods. Twenty-three physical-chemical parameters were analyzed in the water quality laboratory of Arba Minch University, out of which five parameters were analyzed using a multi-meter at the field. The physicochemical water quality analysis result of Lake Chamo revealed that the constituent’s concentration did not show significant variation spatially. The factor analysis result in the Lake Chamo revealed that it had extracted seven principal components that can be explained with a total variance of 86.3%. More than 65% of the monitoring stations in Lake Chamo have an acceptable water quality for irrigation. Moreover, some of the monitoring stations, closer to high human activities, are relatively more polluted than others. Besides, some sensitive parameters such as turbidity have clearly shown that the WQI value can be changed with the parameters changing. Based on clustering analysis, most (47%) of the monitoring are characterized by the recipients of uncontrolled public and state farm and agricultural wastes. The study recommends integrated watershed management and source-based pollution control, which could significantly decrease the pollution level in Lake Chamo after identifying the pollution hotspot areas. Continuous Lake water quality monitoring is necessary for deciding lake pollution.

The purpose of this research was to see whether there was an influence of media exposure (X1) and the quality of information (X2) on the @lrtjkt instagram account on buying interest (Y) LRT Jakarta public transportation services. This research uses SOR (Stimulus-Organism-Response) theory with qualitative menthod with positivism paradigm. The data collection techique was carried out using a questionnaire method in the form of several statements which were then filled out by all respondents. The respondents in this research is followers of the instagram account @lrtjkt which were calculated using the Slovin formula so that a total sample is 400 respondents. The sample that will fill out the questionnaire is selected using the quota sampling technique. The results of the study show that media exposure and the quality of information on the @lrtjkt instagram account have a positive influence is 43.2% on buying interest LRT Jakarta public transportation services and remaining 56.8% is influenced by other factors outside the research. In the F-test, the calculated f-value is 152.867 > f-table 3.018 and the Sig. value is 0.000 < 0.05. While the T-test, the calculated t-value on the media exposure (X1) is 11.050 > t-table 1.966 and the Sig. value is 0.000 < 0.05 and the quality of information (X2) is 5.640 > t-table 1.966 and the Sig. value is 0.000 < 0.05. Based on these tests, it can be concluded that the overall hypothesis is stated that Ho is rejected and Ha is accepted.
Εἰκών bei Paulus

Εἰκών in Paul. “And God said, Let us make man in our image (ποιήσωμεν ἄνθρωπον κατ ̓ εἰκόνα ἡμετέραν)...” (Gen 1:26). One assumes that this meaningful phrase has left many traces in the New Testament. But if one looks at the occurrence of the word εἰκών, it becomes quite clear that it has a special theological meaning only for Paul. For him, the word expresses the extraordinary dignity of the human being. In my article I would like to explore this theme and compare Paul’s thoughts on εἰκών with Philo’s concept of εἰκών. In my article I would like to discuss the topic in three points. First, we will brief-ly look at the εἰκών motif in Genesis. Then we will see how Philo understood the image of God. And at the end we will arrive to Paul.
Amikor (látszólag) semmi sem történik – A fontolgatás mint a változás feltétele
Authors: SIBA Balázs

When (Seemingly) Nothing Happens – Reflection as a Precondition for Change. This is the first of an eight-part series of essays primarily for young adults and those helping them to grow up (parents, teachers, mentors). The entire series deals with the “heroic journey” of growing up, following the monomyth transformation scenario described by Joseph Campbell. This archetypal journey begins with the prelude to change, with the discovery of worlds outside “my world”. Contemplation is part of all our lives, even if we do not foster it so consciously. Whether it takes the form of talking to others, an inner monologue, or a prayer to God, contemplation is important because together with pondering it can be a precursor to life-changing events. Change begins with a sense of lack, of being unsettled, but losing focus is part of the search for a way out. It is usually not easy to remain in a state of cluelessness, of being at a loss, but being out of focus is a chance to deepen our connection to ourselves and to move inner energies that can intuitively help us to find the solution to our questions of life.

Kentang merupakan tanaman pertanian penting karena merupakan sumber karbohidrat yang menjadi bahan makanan pokok di Indonesia. Namun produktivitasnya terancam oleh cendawan patogen oleh karena itu diperlukan usaha pengendalian hayati menggunakan cendawan antagonis. Penelitian ini bertujuan untuk mengetahui aktivitas antagonis cendawan Rhizosfer terhadap cendawan patogen pada tanaman kentang. Cendawan Rhizosfer kentang diisolasi dan diuji daya antagonisnya menggunakan biakan ganda. Sebanyak 22 isolat cendawan berhasil diisolasi dari Rhizosfer tanaman kentang, dan 3 isolat berpotensi menghambat pertumbuhan F. oxysporum dan 5 isolat berpotensi menghambat pertumbuhan Culvularia sp. Aktivitas penghambatan ditunjukkan oleh 8 isolat cendawan yaitu Aspergillus sp. (3 isolat), Nigrospora sp. (1 isolat), Gliocladium sp. (1 isolat) Penicillum (1 isolat) dan Rizopus sp. (3 isolat) menunjukkan kemampuan kompetisi.

Air sumur yang layak dikomsumsi harus memenuhi berbagai kriteria. Biji kelor menjadi objek penelitian karena memiliki banyak kegunaan dan dimanfaatkan dalam berbagai industri dan obat karena memiliki potensi bakterisida. Penelitian ini bertujuan untuk mengetahui adanya pengaruh pemberian biji kelor (Moringa oleifera Lamk.) terhadap pertumbuhan bakteri Escherichia coli pada air sumur. Sampel diambil dari air sumur pondokan yang mengandung bakteri Eschericia coli yang melebihi ambang batas yaitu > 2400 sel/ 100 ml air. Air sumur yang diberi perlakuan dengan menggunakan serbuk biji kelor dengan konsentrasi antara 0,05 gram, 0,1 gram dan 0,15 gram dicampurkan dengan beberapa tetes air sampai berbentuk pasta. Air bersih yang diperoleh, diambil sebanyak 100 ml lalu diuji secara bakteriologis dengan metode Most Probable Number (MPN). Pemberian serbuk biji kelor sebanyak 0,05 gram belum mampu menghambat bakteri dengan nilai total MPN masih mencapai > 2400/ 100 ml air sedangkan 0,1 gram mampu menurunkan jumlah bakteri sekitar 460/ 100 ml air dan 0,15 gram sekitar 210/ 100 ml air.

DNA barcoding merupakan suatu teknik identifikasi spesies berbasis molekuler dengan menggunakan gen Cytochrome C Oxydase Subunit 1 (CO1). DNA barcoding terhadap famili Bovidae berguna dalam rangka identifikasi spesies, monitoring perdagangan daging ternak, penegakkan hukum, serta klarifikasi spesies dalam suatu produk pangan yang berasal dari hewan ternak. Penelitian ini bertujuan untuk mengetahui efektivitas gen CO1 sebagai DNA barcode dengan melihat  jarak genetik antar-spesies dan inter-spesies Bovidae dengan spesies outgrup serta kekerabatan spesies dalam konstruksi filogenetik. Analisis sekuen CO1 dilakukan terhadap tujuh spesies Bovidae dan dua spesies out grup. Data sekuen CO1 diperoleh dari NCBI (https://www.ncbi.nlm.nih.gov/) lalu dilakukan analisis jarak genetik dan filogenetik menggunakan metode neighbor-joining (NJ) pada software Moleculer Evolutionary Genetics Analysis (MEGA) versi 6. Hasil penelitian menunjukkan jarak genetik intra-spesies Bovidae berkisar antara 0,044-0,69% dengan jarak terendah terlihat pada spesies Bos taurus (0,044%) dan tertinggi pada spesies Bos javanicus (4,69%). Sedangkan jarak genetik inter-spesies berkisar antara 2,2-24,6% dengan jarak tertinggi ditunjukkan oleh Bos javanicus dan spesies outgrup yakni sebesar 24,6% (rata-rata ±2,2-0,05%). Sekuen gen CO1 pada spesies famili Bovidae menunjukkan adanya variasi yang tinggi antar-spesies namun rendah dalam spesies (intra-spesies). Oleh karena itu, gen CO1 efektif digunakan sebagai DNA barcode pada famili Bovidae.
