The “Nets and Anchors” on the Indian Community in Mwanza City (Tanzania): Ethnographic Challenges and Encounters
Authors: Sumara Kerindo Abeid
Published: April 2023

The use of “nets and anchors” framework requires a researcher to get a broad perspective of life in the case-study area through everyday observations and conversations with its residents before attempting an in-depth perspective of life as it is narrated by the key respondents of community groups. This framework was adopted in a study conducted among the Indians living in Mwanza City, Tanzania during the period of COVID-19 pandemic. This paper discusses the challenges encountered when conducting ethnographic research on the socio-cultural practices of Indians in Mwanza. The paper points out that COVID-19 pandemic among other factors hindered the process of collecting data through participant observation and interviews on the Indian community in Mwanza City.
Failure of Ujamaa in Modernising Wataturu Community in Igunga from the Early 1970s to the the Mid-1980s
Authors: Ayo Stephano Lazaro
Published: April 2023

Tanzania’s Rural Development Policy which encompassed, among other things, establishment of well-planned Ujamaa villages across the country, was a nation-wide agenda implemented immediately after the Arusha Declaration of 1967. The Arusha declaration marked the actual beginning of Ujamaa, a socio-economic policy based on egalitarian principles of traditional African societies practiced in Tanzania from 1967 to the mid-1980s. Contrary to government’s intentions, the Wataturu negatively responded to this programme since it conflicted with their socio-cultural set-up. Scholarships on this subject converge on the failure and success of the programme, its ecological impact as well as land disputes and social unrest resulting from the implementation of the policy. Yet, little is known about the extent to which the socio-cultural life, perceptions, beliefs, and cattle economy determined the responses, participation and mobilization among the Wataturu (brediga) - Datooga of Igunga. This paper exploits ethno-historical accounts from Igunga district and archival materials collected as part of a PhD project to fill this gap. The paper establishes that modernisation through the resettlement scheme and establishment of Ujamaa villages were never a reality for the Wataturu who uphold their traditional socio-cultural set-up with great pride.

Published: April 2023

Bacteroides xylanisolvens Y-11 and Bifidobacterium longum y37 isolated from human gut were found to inhibit each other's growth after co-culturing in previous studies. To further reveal the potential mechanism of mutual inhibition between them, ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to investigate the metabolic changes of the strains after monoculture and co-culture, and the key differential metabolites were subject to the validation. The results showed that the types and amounts of metabolites were significantly changed during co-culture, with hydrocarbons and their derivatives, organic acids and esters being the main differential metabolites, which posed a greater influence on the metabolism of B. xylanisolvens Y-11 than on B. longumy y37. Further studies suggest that cycloserine and succinic acid may be the main metabolites that inhibit the growth of both strains, and the decrease of pH may be the main reason for succinic acid to inhibit the growth of the two strains. Moreover, B. longum y37 played a dominant role in the co-culture and its metabolites influenced the growth of B. xylanisolvens Y-11 to a greater extent. This study provides a new perspective for further understanding of the interaction between intestinal microbes and the influence of intestinal microecology on the occurrence and development of diseases.
Active Transport and the Journey to Work in Northern Ireland: A Longitudinal Perspective 1991-2011
Authors: Shuttleworth Ian , Feehan Claire
Published: April 2023

Policy interventions to encourage the use of healthy and sustainable modes of travel to work (such as walking and cycling) have encountered varying levels of success. In areas such as Northern Ireland, and cities such as Belfast, the car remains the dominant mode for journeys to and from work. This paper explores why this is the case by examining the individual, household, and geographical factors that govern (a) changing between one census and another to walking or cycling from other transport modes; (b) changing from walking or cycling; and continuing to walk or cycle. The analysis is undertaken using the Northern Ireland Longitudinal Study (NILS), a 28% random sample of the population. The results show that walking or cycling is associated with lower-status jobs, urban locations, with no clear association with better self-reported health. In contrast, car commuting is associated with better education, health, and higher labour market status. The analysis shows that policies to encourage the use of more sustainable and less polluting transport face formidable barriers from status perceptions, time budgets, and the geographical contexts of Northern Ireland and Belfast.

Authors: Kourtit Karima , Nijkamp Peter , Scholten Henk
Published: April 2023

Local energy transition initiatives – as part of a broader climate-benign and sustainability policy – have become a focal point of future-oriented resource and environmental strategies. Place-based energy conversion however, has turned out to be a very complicated task, from both a governance and research perspective. The present study seeks to sketch out the contours of local sustainable energy planning, with a particular emphasis on (i) practical data and evidence-based information requirements, (ii) the involvement and engagement of citizens and stakeholders, and (iii) the great research potential provided by digital information technology. To that end, a comprehensive mind map for energy transition is depicted, inspired by first experiments in the city of Rotterdam.
How Does Quality of Life (QOL) Affect Attractiveness of Cities and Internal Migration in Turkey?
Authors: Özer İsmet Selçuk , Türk Umut
Published: April 2023

The management of internal flows can bring significant benefits to a country in balancing the opportunities between regions or cities. To tackle unequal access to opportunities, the factors that induce internal migration should be understood. This study examines a set of pull and push factors for internal migration by spatial econometric analysis and GIS applications. We find that when the accessibility of amenities increases, the city becomes more attractive and preferable for migrants. In addition, socioeconomic factors also play a significant role in the decision-making process of migrants. In this study, we used a panel dataset that includes socioeconomic and contextual data such as distances to the amenities for each Turkish city in the years between 2012 and 2021. The results show that, in Turkey, internal migration flows from the East to the West, where opportunities are better. Finally, the human capital level of migrants can cause a variety of thoughts about factors, and it can change the order of significance of the variables for people who have a different level of human capital such as education level. Based on the findings, the paper offers several policies suggestions for ensuring a balanced migration in Turkey.
Exploring Organic Food Purchase Behaviors of Gen Z: An Application of TPB and MOA Model in a Transition Country
Authors: Nguyen Phuong Mai , Vo Nam D.
Published: April 2023

This article investigates the predictors of purchase behavior of the generation Z (Gen Z) in the Vietnamese organic food sector. We proposed a research model by extending the theory of planned behavior (TPB) with the motivation–opportunity–ability (MOA) framework to address the gap between purchase intention and behavior in the organic food market. Data from a self-administered online survey with 426 respondents living in the three biggest cities of Vietnam were analyzed in SmartPLS software to test proposed hypotheses. Our findings show that trust is the most crucial factor affecting the purchase behavior of Gen Z in the Vietnamese organic food sector. Notably, perceived barriers (PB) were found to positively influence purchase behavior. The present study suggests the organic food producers and suppliers to change their marketing strategies and policies in response to the demanding Vietnamese Gen Z.

Authors: Stavar Angelica Nela , Rugină Sorin , Adam Tatiana
Published: April 2023

Introduction. The infection with hepatitis C (HCV) is a major cause of chronic liver diseases, with approximately 71,000.000 chronically infected persons worldwide.

Material and methods. This study includes the results of the evaluation of the quality of life of patients with chronic hepatic diseases, on a group of 122 patients divided into two lots. The study period was January 2020 - december 2022. Our aim was to study the impact of the antiviral therapy on the patients quality of life before and after the interferon free antiviral therapy, as well as to study the quality of life of the patients with chronic viral hepatitis C who did not receive interferon free antiviral therapy because they did not meet the eligibility criteria, but accepted to participate in the study.

Results. Following the analysis and the interpretation of the questionnaire used, we found that the patients who did not receive the treatment presented more frequently a psychosocial unbalance (social activities), psychoemotional and loss of interest for the sexual activity. In the case of patients treated with interferon free regimens we found an improvement of the quality of the whole duration of the therapy, this being correlated, especially, with drug interaction that were limited or easily manageable and had minimal adverse effects, increasing psychoemotional, balance, and the sexual activity was not influenced.

Conclusions. The results of our study indicate that the patients who were treated with the antiviral interferon free therapy become aware the fact that the problems related to the chronic hepatic disease are solvable, which influences the quality of life in a positive way.

Introduction. Hepatic steatosis represents a common pathological feature in patients with chronic viral C infection and can be independently associated with obesity, increased alcohol consumption, type 2 diabetes, and hyperlipidemia. These factors can contribute to the development of hepatic steatosis in patients with chronic HCV (Hepatitis C virus) infection.

Materials and methods. 64 patients who underwent treatment with oral antivirals were included and evaluated through non-invasive methods for the degree of hepatic steatosis.

Results. After at least 3 months of sustained viral response, all patients with advanced hepatic steatosis were categorized into lower classes in the Steatotest evaluation.

Conclusion. This study highlights the importance of direct acting antiviral (DAA) treatment in the medical care of patients with chronic viral C infection and hepatic steatosis. Thirty years after the discovery of the hepatitis C virus, treatment with oral antivirals revolutionizes the medical care of patients with this chronic infection.
The Impact of Technical Skills and Education on Exacerbations, Adherence to Treatment and the Choice of Inhaler Device in Patients with COPD
Authors: Bivolaru Sorin , Constantin Ancuţa
Published: April 2023

Introduction. The largest challenge for patients with COPD is the correct use of inhaler devices. In COPD, inhalation therapy has a key role in symptom control, reducing the exacerbation rate, hospitalization and improving the quality of life. Choosing the active substance(s) administered by inhaler devices is an easy task because of the Gold guideline recommendations, but, when it comes to choosing the inhaler device, it is much more difficult to get recommendations.

Methods. Our analysis included 200 subjects divided into two groups and its objective was the identification of some mechanisms that connect education, exacerbation and adherence to treatment, placed in the context of measuring technical skills and patients` preference for a particular inhaler device. All subjects included in the analysis were subjected to a technical skills test that included a set of 10 questions with a 30-minute solving time. The subjects in the working group were put in the position of deciding factor for the choice of an inhaler device, and implicitly for the treatment they would follow during monitoring.

Results. In both groups, the lowest treatment dropout rate at T12 was recorded among those with higher levels of education, while those with poor education levels recorded very high dropout rates. In both groups we noticed that, as the level of education increased, technical skills were also increasingly better. Both in the control group and in the working group, dropout subjects at T12 had significantly lower technical skills compared to subjects who did not drop out. The level of technical skills was significantly lower in both groups in subjects with exacerbations. Statistical analysis proved the relationship between the low level of technical skills and exacerbation. The subjects with lower technical skills proved to be more prone to dropout of inhaler therapy as well. The proportion of subjects with exacerbations in the control group was significantly higher than the proportion of those with exacerbations in the work group. The proportion of subjects with exacerbations in the control group was significantly higher than the proportion of those with exacerbations in the work group.

Conclusions. The authors consider that the involvement of the patient in choosing the inhaler device had a positive impact on disease control and reducing the rate of exacerbations.

Authors: Moales Elena-Andreea , Zota Ioana Mădălina , Tribus Laura Carina , Cozma Corina Dima , Mitu Florin
Published: April 2023

Chronic obstructive pulmonary disease (COPD) and atrial fibrillation (AF) are common pathologies in the elderly patient. The simultaneous occurrence of the two conditions influences the quality of life and increases the rate of exacerbations. About two-thirds of patients with atrial fibrillation have dyspnea. Severe dyspnea in the patient with COPD and AF can be difficult to manage, suggesting an exacerbation of the disease, the onset of atrial fibrillation or even a symptom of associated comorbidities, the most common of which being heart failure.

The risk of developing AF in COPD increases with the severity of airflow obstruction. Factors such as smoking, aging, dyslipidemia, the presence of diabetes, hypertension or heart failure influence the prognosis of patients with COPD and AF. Furthermore, oxidative stress, hypoxia, systemic inflammation or immunological changes decrease the survival rate and may favor the recurrence of AF. In the evolution of concomitant COPD- FA cases, proinflammatory cytokines such as tumor necrosis factor α (TNF-α), monocyte chemotactic protein (MCP-1), interleukin-6 (IL-6), interleukin-8 (IL- 8) intervene.

This paper aims at analyzing data related to the factors that would influence the prognosis of patients with COPD and AF.
Efficient Heat Recovery from Hydrogen and Natural Gas Blend Combustion Products
Authors: Rusovs D. , Jansons L. , Zeltins N. , Geipele I.
Published: April 2023

The introduction of hydrogen and natural gas blends in existing gas transportation and distribution networks would ensure faster and more efficient decarbonization of energy sector, but, at the same time, this process would request solution of many practical and technical problems. This paper explores thermodynamics of hydrogen and natural gas blend combustion products and estimates the amount of condensate and latent energy recovery from flue gas as a function of condensing temperature. The efficient energy recovery depends on network return temperature, and it is possible to overcome this limitation by implementation of heat pump for extraction of low temperature heat from flue gases. The case study considers operation of heat only boiler and flue gas condenser with integrated cascade of heat pumps, which consist of absorption lithium bromide-water chiller (in heat pump mode) and vapour compression unit. Presented results of energy recovery hence are limited by data collected from the natural gas combustion for district heating network energy supply. However, previous thermodynamic consideration allows extending the obtained results for case of hydrogen and natural gas blend combustion. A proof of concept of heat recovery by combination of flue gas condenser supported by a cascade of heat pumps demonstrates the efficiency in case of hydrogen and natural gas blend combustion.
The Predicition of Solar Flares Using Millimeter Radio Brightenings
Authors: Kallunki J.
Published: April 2023

Solar activity could have significant impacts on various Earth and near-Earth space systems, such as satellite communication and power grid systems. The prediction of solar activity and active solar events plays a major role when preparing for these disturbances. Various satellite-based instruments constantly observe the Sun. However, only a few ground-based solar instruments could provide versatile enough information for the space weather prediction. Metsähovi Radio Observatory of Aalto University (Finland) has a unique collection of millimetre (8 mm) solar radio maps over the past 40 years, and even denser observational solar radio data catalogue since 2011. About 75–80 % days yearly are covered nowadays. This gives opportunity to make statistical estimation of solar flare occurrence based on solar radio maps. In this study, we had 2253 days when both solar radio map and GOES (Geostationary Operational Environmental Satellites) classified solar flare were observed. In this work, we used solar flare classification done by the Space Weather Centre (SWC) of the National Oceanic and Atmospheric Administration (NOAA). The data were observed between 1 January 2011 and 12 September 2022. Our study shows that the maximum intensity of radio brightenings is a good indicator to tell which kind of GOES classified solar flare could be expected to happen. The article presents that intense radio brightening is needed to produce a certain GOES classified solar flare.
Radio Measurements of Coronal Magnetic Fields in Fan-Spine Configurations on the Sun
Authors: Ryabov B. , Vrublevskis A.
Published: April 2023

Recent interest of solar physicists in the analysis of the coronal mass ejections and circular solar flares in fan-spine magnetic configurations (FSCs) necessitates measurements of the corresponding coronal magnetic fields. A dominant sunspot with the circumjacent magnetic flux of opposite polarity produces a specific coronal region of the quasi-transverse (QT-) propagation of microwaves. We make use of the theory of QT-propagation to evaluate the strengths of coronal magnetic fields in the active regions NOAA 11579, 12242, and 12488 while they are non-flaring. Microwave polarization changes were observed with the RATAN-600 radio telescope, the Siberian Solar Radio Telescope, and the Nobeyama Radioheliograph. Changes in the sign of circular radio polarization provide the strengths of coronal fields in a QT-region if the coronal plasma density N
e and the length scale of magnetic field divergence L
d are known. We evaluate the length scale by means of the potential-field source-surface (PFSS) model and the coronal density from the Gaussian inversion of the differential emission measure (from the Solar Dynamics Observatory observational data), obtaining N
e
L
d = (0.46–0.64)×1010 m−2. The resulting coronal fields of 1.4×10−3 T and 2.34×10−3 T are attributed to the heights of 100 Mm and 50.2 Mm. We discuss the validity and consistency of the involved values to draw conclusions on the feasibility of coronal radio magnetography of FSCs.

Published: April 2023

Nowadays, the use of quadcopters in daily life has become important due to its capabilities and ability to carry out many tasks in many fields like civil, military, industrial, and agricultural fields. The modelling of the quadcopter and deeply understanding its movements is very important to ensure that the simulations of its behaviour are as close as possible to reality and also helps us to design a flight controller. In this work, we used a modern technique on MATLAB (Simscape) to simulate a quadcopter in real-time. At first, we build a quadcopter using Simscape multibody then we simulated the PID regulator, the command algorithms, and the motor model with the applied forces on the body to achieve the global model that we can use to study the movement of the quadcopter on the three-axis which ensure a stable functioning. The results obtained show the stability of the four movements of the quadcopter (roll, pitch, yaw, and altitude).

Demography and Population Growth in 1970’s Romania: An Overview of Demographic Studies Published in ‘Viitorul Social’ Journal
Authors: Pop Oana
Published: April 2023

This paper looks at how demographic knowledge was articulated in the 1970s in Romania in a context shaped by both a restrictive natalist agenda and the reestablishment of institutional affiliations with western academia. An account is given of the specific institutional affiliations that coordinated and made knowledge transfers possible between French and Romanian agencies. The text then focuses on the specific vocabulary and reasoning mechanisms employed in a series of texts published throughout the 1970s in the sociological journal Viitorul Social, a monthly magazine of socialist doctrine, culture and politics. The aim is to start a discussion about the possibility that the reestablishment of institutional connections with French demographic trends in the early ᾿70s lent Romanian demographers a type of conservative scientific reasoning and vocabulary that was attuned to the natalist politics of the time. In turn, this authorised a highly politicised portrayal of working-class women as culpable for the diminishing birth-rates in Romania. The text ends by suggesting other research paths that might help situate demographic knowledge production and its ties with reproduction politics.
Balancing Efficiency and Personal Time Requirements for Human Resources Professionals after Telecommuting
Authors: Țoiu Andreea
Published: April 2023

The exploitation of work and household responsibilities among women and men remains a pressing issue with significant impacts on employee productivity and satisfaction. This study sheds light on the patterns of exploitation and their consequences, with a specific focus on the experiences of HR professionals. The research emphasizes the prevalence of the “flexibility stigma” in society, which views flexible work arrangements, including teleworking, as less committed, motivated, and productive compared to traditional 9-5 work hours. The study also highlights the tendency for workers to extend their work hours when boundaries between work and personal life become blurred. In particular, the study highlights the increased likelihood of working overtime as a result of teleworking, which can further contribute to the exploitation of work and household responsibilities. For HR professionals, it is essential to understand these challenges and develop strategies that support employees’ work-life balance and well-being. The study concludes by calling for a comprehensive approach that considers the institutional and cultural contexts in which employees operate and that prioritizes their well-being and productivity.
Analysis of Transport Conditions for Frozen Food on the Way from the Shop to Home
Authors: Góral-Kowalczyk Małgorzata , Góral Dariusz , Nakonieczny Piotr
Published: April 2023

The transport of temperature sensitive products takes place under special conditions defined by specific agreements and international standards. The only exception to this rule is consumer transport. This transport is carried out by the consumer and takes place on the way home from the shop. The study examined consumers' awareness of the consumer transport of frozen food and analysed this type of transport in terms of the continuity of the cold chain. Such situation affects the deterioration of frozen food quality especially in case of its later storage in the home freezer. It was found that the average distance that customers cover from shop to home was 4.98 km. They usually used a car and covered this distance in an average of 12.85 minutes. During the summer months, this time is sufficient to partially thaw a package of frozen vegetables. Only 33% of the respondents used insulated bags to protect frozen food on the way home. When analysing the transport of frozen raw material carried out by consumers in real conditions, the use of insulated bags was found to be justified. These bags are able to keep the temperature of the packed raw material below −5°C. It was found that the legal imposition of the necessity to use such bags or the introduction by the manufacturer of frozen food of appropriate packaging protecting the food against transport at inappropriate temperatures in the summer months is necessary.

Authors: Bolimera Anudeepsekhar , Muthalagu Raja , Kalaichelvi V. , Singh Abhilasha
Published: April 2023

Ego lane detection is one of the key techniques in Ego Lane Analysis System (ELAS) implemented in smart autonomous driving cars for lane detection in roads. This technique has been extensively studied in recent years because of its accurate and robust detection of shape and location of lanes. The conventional methods are less robust and computationally expensive since they have several challenges in localization of lanes due to presence of occlusions on roads. So to avoid these issues, this paper uses a novel 2-stage lane detection method using deep convolutional neural network to detect the lanes and its key-points by optimally fit a curve to the lane to compensate on above mentioned issues. The proposed methodology for lane detection predicts the key-points accurately and it robust under various weather conditions and highway driving scenarios. In terms of performance, this technique is fast and robust with low computational cost and has high performance when deployed on autonomous vehicle-based systems.
Fractional Vehicle Ownership and Revenue Generation Through Blockchain Asset Tokenization
Authors: Vitelaru Elena , Persia Luca
Published: April 2023

The automotive industry is on a continuous transition towards a more sustainable and integrated ecosystem influenced by the fast-paced adoption of Electrical Vehicles (EVs) and the developments of emerging technologies such as Automated Vehicles (AVs). The road transportation sector is also experimenting with the emergent decentralized blockchain technology in various ways ranging from supply chain transparency to insurance and tokenization. Some of the recent use cases are the use of Non-Fungible Tokens (NFTs), unique digital assets designed to be immutable, to certify ownership of a vehicle, the data history of it or just for fan base development. The current paper reviews the literature findings concerning the potential of Non-Fungible Tokens for the automotive industry and proposes a new car ownership and revenue generation model using the ERC-1155 token standard. Our proof-of-concept based on fractional vehicle ownership demonstrates the feasibility of such a model that allows for revenue distribution amongst the vehicle owners according to the percentile invested in the vehicle acquisition.
A Microscopic Analysis of the Relationship Between Prior Knowledge About Self-Driving Cars and the Public Acceptance: A Survey in the US
Authors: Othman Kareem
Published: April 2023

Previous studies have shown that the level of awareness of SDVs is a deciding factor that affects the public attitude towards this emerging technology; however, none of these studies focuses on understanding the relationship between these two variables. Thus, this study utilizes a questionnaire survey with the objective of drawing the relationship between the public attitude and level of knowledge. A total of 2447 complete responses were revised from participants from the US. The results show that people with prior knowledge about SDVs are more likely to travel on SDVs. However, participants who know a bit about SDVs were the most likely to travel on SDVs when compared with participants who had no knowledge and participants who know a lot about SDVs. In addition, the analysis shows that the relationship between the level of knowledge and the level of acceptance of SDVs is not linear but rather parabolic.

A Model for Identifying Road Risk Class
Authors: Ryguła Artur , Brzozowski Krzysztof , Maczyński Andrzej
Published: April 2023

In many road safety, traffic management, and travel planning analyses, it is useful to classify road sections according to risk level. Such classification is labour-intensive and needs to be reviewed periodically. The authors propose a model for identifying a discrete risk class for road sections based on selected traffic flow parameters, which are available in most measurement systems monitoring current traffic conditions. The Surrogate Safety Measures approach was applied in the model formulated using Principal Components Analysis. As input to the model SSMs are used in the form of a set of hourly average traffic flow parameters. The SSMs used are: the percentage of light vehicles exceeding the speed limit by a value in the range 21 to 30 km/h; the percentage of light vehicles exceeding the speed limit by more than 30 km/h; the traffic volume of light vehicles; the traffic volume of heavy vehicles and the mean speeds of light vehicles and heavy vehicles.

This paper presents results of calculations of risk class obtained from the model for different locations on single-carriageway two-lane roads in Poland. Satisfactory compliance of risk classes designated by the road operator and identified by the model based on current traffic data was achieved. The proposed model can be used as the core of an effective alternative road safety screening method.

Museum Pustaka Lontar in Karangasem, Bali, has preserved and promoted lontars, the manuscripts that carried the ancient texts of Balinese tradition. This research and development study constructed an English module for the local guides at the lontar museum. The needs analysis derived from the observation of the museum, and interviews with the guides, investigated the guides’ necessities, lacks, and wants in learning English. The result showed that the local guides needed modules where the materials correspond to the guiding sequences of the museum. The materials had to also accommodate the translation of museum lontar-specific terms into English. Conversation-based materials were the most requested, as it resembled their daily interaction with visitors. These findings served as the base for the material development of the English module. Guides, language learners, and teachers in the tourism field might source their learning from the module.

Padina boergesenii is a distinctive small brown algae with rounded fronds growing to a length and diameter of 04 to 06 cm (1.6 to 2.4 in). P. boergesenii is widely present in the shallow water of tropical, subtropical and warm temperate areas. The present study aimed to investigate the anti-bacterial, anti-biofilm, antioxidant, anti-inflammatory and cytotoxicity activities of crude ethyl acetate extract of P. boergesenii. Anti-bacterial activity of crude ethyl acetate extract of P. boergesenii against Gram-positive and Gram-negative bacteria was determined using the well diffusion method. MIC of P. boergesenii against biofilm was carried out by the Resazurin method. Antioxidant potential was assessed by DPPH, FRAP, and the Hydrogen peroxide scavenging method. The anti-inflammatory activity was investigated using the albumin denaturation and heat-induced hemolysis method. Cytotoxicity activity of P. boergesenii against cell line L929 was analyzed by MTT assay. The maximum zone of inhibition obtained was 23 mm for Staphylococcus aureus, followed by 21 mm for Escherichia coli. Biofilm of Enterococcus faecalis showed higher resistance (MIC= 25.00±00.00 mg/mL). Biofilm of Acinetobacter baumannii was found to be most susceptible (MIC= 06.25±00.00 mg/mL). The IC50 value for the crude ethyl acetate extract P. boergesenii was 155.5 μg/mL for the DPPH method, 1567.18 μg/mL for the FRAP method, and 3098.27 μg/mL for the H2O2 method. The results of in vitro anti-inflammatory studies exhibited IC50= 122.33 μg/mL and 2522.40 μg/mL for albumin denaturation assay and heat-induced hemolysis method respectively. The crude ethyl acetate extract of P. boergesenii showed cytotoxicity against the growth of the L929 cell line. The present study suggested that the crude ethyl acetate extract P. boergesenii has potent antibacterial, anti-biofilm, antioxidant, anti-inflammatory and cytotoxicity activities. The bioactive components present in the P. boergesenii extract can be a promising source for pharmaceuticals.

PT ABC is a start-up company that provides an online shopping platform with a variety of daily necessities, one of products offered is Fast Moving Consumer Goods (FMCG). The main problem faced by PT ABC was the total inventory cost that exceeded the budget by 82%. This was caused by the lack of standard inventory policy calculation. To overcome this problem, a proposed inventory policy needs to be designed to obtain the optimal value of reorder point, order quantity, and safety stock. Before designing the inventory policy, inventory classification was conducted using ABC analysis. Then proceed with designing inventory policy using the continuous review method (r, Q) to minimize total inventory cost. After that, a Decision Support System (DSS) was designed based on the results of the proposed inventory policy using Microsoft Excel-VBA. This research resulted the optimal value of reorder point, order quantity, and safety stock were obtained for 42 products in category A with diverse values. Based on the proposed inventory policy, the total inventory cost decreased by 11% or Rp281.770.103/year from the existing total cost. Then, the DSS was successfully designed to assist decision makers in implementing the proposed inventory policy. Although it had been successfully minimized, the total cost of the proposed inventory still exceeded the budget. This was because the current budget had not considered all components of inventory costs, even the budget for purchasing costs with an order quantity of as much as the number of demands was not sufficient.
