Influence of the probe dimensions on the display of the low-frequency dispersion of the earth’s electromagnetic properties for measure-ments in marine waters up to 100 m deep
Authors: Ageenkov E. V. , Sitnikov A. A. , Vodneva E. N.
Published: October 2020

The purpose of the study is to show the effect of the probe dimensions on the display of the low-frequency dispersion of the geological formations’ electromagnetic properties in transient measurements by electric lines in the axial area of the source for the water areas up to 100 m deep. The study analyzes the change in the transient signal, the finite difference, and the transform (the ratio of the above two) as a function of the length of the source (a horizontal grounded electric line (AB) 50 to 2,000 m), the receiver (a three-electrode electric line (MON) 50 to 2,000 m), and the distance between their centers (spacing) 100 to 4,000 m. The values obtained from the conductive and conductive polarizing models are compared for the identical probes installed at the same depth. The grounded electric line is located within the conducting medium with a conductive polarizable base. The conducting medium is associated with the seawater thickness in the marine shelves up to 100 m deep. The conductive polarizable base is a geological environment (earth) covered with a layer of water. The polarizability of the base is registered by introducing frequency-dependent electrical resistivity by the Cole-Cole formula. The calculations show the display of different transient components associated with the transient buildup and the earth’s low-dispersion properties caused by both galvanic and eddy currents. These components manifest themselves differently for the probes with different dimensions of the source line, receiving line, and spacing. Based on the calculations, it can be argued that in the time range from 1 ms to 16 s, at the probes that have different dimensions and are immersed in the water layer up to 100 m thick, the signal changes depending on the immersion depth for “small” installations (AB of 50 and 100 m), while there is no such dependence for the rest of the probes used in the calculations (AB of 250, 500, 1,000, and 2,000 m).
The features of the geological structure of the Verkhnechonsky oil and gas condensate field and their influence on the field development and operation system
Authors: Rapatskaya L. A.
Published: October 2020

The study aims to analyze the relationship between the redetermination of the complexity of the geological structure of the Verkhnechonsky oil and gas condensate field and the schedule adjustment of the field development plans. The paper uses the data on the exploration and production wells obtained from the pilot operation of JSC Verkhnechonskneftegaz, the geophysical work results, and the research materials publicly available in the press. The geological structure of the Verhnechonskoye oil and gas condensate field is unique in its complexity. This is due to the following factors: a combination of tectonic disturbances accompanied by the intrusion of traps; high mineralization of the reservoir water; sharp variability of the filtration and reservoir properties of the producing horizons by area and section due to the unevenness of the lithological composition of the reservoirs, their salinization and complete pinch-out. The development system of any field should take into account the peculiarities of the field’s tectonic and lithological-facies structure, and meet specific technical and economic requirements for drilling and operating wells. The complexity of the field structure requires a thorough selection of a development system that inevitably changes as the features of the field structure are studied, e.g. vertical drilling suggested at the initial stage of the filed development was shortly after replaced with inclined-horizontal drilling with the calculation of two options. Within the pilot operation project of the Verkhnechonsky field, JSC Verkhnechonskneftegaz has developed two variants of uniform grids of directional and horizontal wells with pattern flooding for the most explored deposits of the Verkhnechonsky horizon of blocks I and II. Because of the intensive processes of the reservoirs’ secondary salinization, the flooding method required a study of the reservoir water composition. However, the proposed drilling plan using a downhole engine and gamma-ray logging could not ensure the wellbores ducting through the most productive sections of the horizon, therefore, the flow rates of some directional and horizontal wells were not high enough. To increase the drilling efficiency, the specialists of the Drilling Department (JSC Verhnechonskneftegaz), together with the Department of Geology and Field Development (Schlumberger Ltd.), proposed a new methodology that increases the drilling efficiency by using a rotary-controlled system, logging-while-drilling, and geosteering. Thus, the development system of the Verkhnechonsky oils and gas condensate field was changing in the process of specifying the field’s geological structure, anisotropy reservoir properties, and the thickness of the producing horizons in size and cut, their salinization and pinch-out, and the composition of the reservoir waters.

Published: October 2020

Liquid liabilities are required to develop key sectors that drive the Nigerian economy by ensuring that loans are available for investment purposes. However, controversies concerning the effectiveness of growth finance in fostering liquid liabilities in Nigeria exist. Thus, this study examines the relationship between growth finance and liquid liabilities in Nigeria, with insight into Nigeria’s real sector. In achieving its objective, the study utilizes secondary data from the annual reports of the Central Bank of Nigeria (1980–2018). The study finds that gross domestic savings significantly drive liquid liabilities in the long run compared to other growth finance indicators, which include stock market development and remittance inflows. Therefore, the study recommends that to improve liquid liability, gross domestic savings, among other growth finance indicators, should be harnessed as a tool to efficiently influence liquid liabilities in the Nigerian economy. The study concludes that attention should be paid to development policies that drive all stakeholders’ gross domestic savings.

THE URGENCY OF APPLYING JOURNALISTIC ETHICS IN ONLINE ISLAMIC MEDIA REPORTING ACTIVITIES: A CONCEPTUAL STUDY
Authors: Fitri Fitri - , Adeni Adeni -
Published: October 2020

This article aims to study the urgency of applying journalistic ethics in online Islamic media activities. The study focuses on analyzing the seven standards of Islamic Media Literacy from Indonesian Ministry of Religion, namely (1) principles of online news production, (2) news distribution ethics, (3) accuracy and anti hoax, (4) the spirit of amar ma'ruf nahyi munkar, (5) principle of wisdom in da'wah, (6) principles in digital interaction, and 7) principle of press freedom. By using the qualitative method of library research, we argue that these seven principles could be said as journalistic ethics that must be applied in Islamic media reporting activities. These values are extremely important for Islamic media activities because the credibility of journalists and media institutions is related to public assessment which is quite determining the continuity of media life. The news in online Islamic media has different characteristics from other media. Online Islamic media cannot avoid how a text or symbol is presented in the category of fundamentalism-radicalism or moderate Islamic ideology. Problems arise when the radical Islamic ideology is more dominant than moderate Islamic ideology so that it is not uncommon for the Islamic media to get caught up in provocative actions which in some limits create disharmony for people's lives. If that is the case, the application of peaceful journalistic values becomes important to display Islamic da'wah of rahmatan li alamin.

In the era of digital technology the role of the media is very important in changing people's habits and becoming an important part in the lives of social communities. The existence of the media now greatly influences the culture of the community in obtaining information, but the negative side is that the media can control the community and make it subject to the rules made by the media itself. Go-food is present as a medium that makes it easy for people to meet the needs of high urban mobility. The business or trade sector is a sector that has an important role in the process of producing goods and services. The research method uses a cultural studies approach (cultural studies) in examining the Go-food phenomenon which is reflected in the socio-cultural context of the urban consumer society. Data collection techniques using the study of literature. The results showed that Go-food succeeded in mediating and changing the order of habits of users in meeting food needs through the media. There is a process by which the community begins to depend on the application and the existence of power which results in the community being subject to the rules that are made.

 
Coincidence probability of streamflow in water resources area, water receiving area and impacted area: implications for water supply risk and potential impact of water transfer
Authors: Wei Xingchen , Zhang Hongbo , Singh Vijay P. , Dang Chiheng , Shao Shuting , Wu Yanrui
Published: October 2020

Under changing environment, the feasibility and potential impact of an inter-basin water transfer project can be evaluated by employing the coincidence probability of runoff in water sources area (WSA), water receiving area (WRA), and the downstream impacted area (DIA). Using the Han River to Wei River Water Transfer Project (HWWTP) in China as an example, this paper computed the coincidence probability and conditional probability of runoff in WSA, WRA and DIA with the copula-based multivariate joint distribution and quantified their acceptable and unfavorable encounter probabilities for evaluating the water supply risk of the water transfer project and exploring its potential impact on DIA. Results demonstrated that the most adverse encounter probability (dry–dry–dry) was 26.09%, illustrating that this adverse situation could appear about every 4 years. The acceptable and unfavorable probabilities in all encounters were 44.83 and 55.17%, respectively, that is the unfavorable situation would be dominant, implying flood and drought risk management should be paid greater attention in project operation. The conditional coincidence probability (dry WRA & dry DIA if dry WSA) was close to 70%, indicating a requirement for an emergency plan and management to deal with potential drought risk.
Mitigate water shortage by improving hydropower generation strategy of the cascade reservoir system in the Be River Basin, Vietnam
Authors: Thi Thuy Linh Nguyen , Chou Frederick N.-F.
Published: October 2020

To meet increasing water consumption with limited water resources, management approaches that transfer water between purposes must be improved for sustainable development. This entails an urgent requirement for appropriate water resources management within water–energy interaction if severe water shortage occurs occasionally. This study evaluates hydropower generation policies of a cascade reservoir system in the Be River Basin in terms of security of water supply and energy production. The Generalized Water Allocation Simulation Model (GWASIM) was applied to simulate the water use of a complex system of hydropower generation and water supply. Two water allocation scenarios and six alternatives defined by varying monthly generating hours were modeled and compared. The results demonstrate that a compromise between hydropower generation and water supply can be negotiated to reduce the severity of water shortages. Different monthly hours of hydropower generation among alternatives show an effect on improving power production and reliable water supply. This study provides overall insight into the performance of a multi-purpose cascade reservoir system. It will provide a foundation for improving future study of reservoir operations in meeting the increasing demands of water and energy in Vietnam.

Authors: Thinojah T. , Ketheesan B. , Herath G. B. B.
Published: October 2020

Groundwater contains iron (Fe) that can be difficult to remove by singular physical–chemical methods. The aim of this presented study was to investigate the suitability of up-flow aerated filters as an upgrading step for the removal of total Fe from groundwater. Granular activated carbon (GAC) was applied as a pollutant carrier and compared with Bio-Pac media (BPM) by conducting a column test to treat synthetic groundwater (SGW). Initially two adsorption kinetic studies were done for GAC. The effect of influent Fe concentration, hydraulic retention time (HRT) and air supply to the system were investigated using a column experiment. The sorption result follows pseudo-second-order kinetics with an adsorption amount of 1.36 mg/g. The column experiment results show that around 99% and 70% Fe removal efficiency can be achieved for the best condition of 3 mg/L influent Fe concentration with seven hours HRT for GAC and BPM respectively. The air supply into the column did not show any improvement in Fe removal efficiency. The performance of GAC is found to be much better than that of BPM. All over, the new combined treatment method of aeration followed by filtration was demonstrated to be an effective technique for Fe removal from groundwater and also satisfied the World Health Organization (WHO) drinking water standard for Fe concentration.

Authors: Wu Guangxue , Zhang Tianqi , Gu Mengqi , Chen Zhuo , Yin Qidong
Published: October 2020

Wastewater management has experienced different stages, including pollutant removal, resource recovery, and water nexus. Within these stages, anaerobic ammonia oxidation-based biotechnology can be incorporated for nitrogen removal, which can help achieve sustainable wastewater management, such as reclamation and ecologization of wastewater. Here, the physiology, metabolism, reaction kinetics and microbial interactions of anammox bacteria are discussed, and strategies to start-up the anammox system are presented. Anammox bacteria are slow growers with a high doubling time and a low reaction rate. Although most anammox bacteria grow autotrophically, some types can grow mixotrophically. The reaction stoichiometric coefficients can be affected by loading rates and other biological reactions. Microbial interactions also contribute to enhanced biological nitrogen removal and promote activities of anammox bacteria. The start-up of the anammox process is the key aspect for its practical application, which can be realized through seed selection, system stimulation, and biomass concentration enhancement.

Published: October 2020

Among the different antibiotics, tetracycline hydrochloride (TCH) is one of the most commonly used. In this study, the activated sodium persulfate (SPS) process induced by microwave (MW) energy was used to treat TCH. The effect of different operational parameters of MW/SPS-treated TCH, such as SPS concentration, TCH concentration, initial pH, and MW power, was investigated. The concentration changes of TCH were determined using a spectrophotometer. The results of radical scavenger experiments indicated that the sulfate radical () was stronger than the hydroxyl radical (·OH). On the basis of high performance liquid chromatography–mass spectrometry (HPLC–MS) analysis, a possible degradation pathway of TCH was proposed. This research indicates that the MW/SPS system is a promising prospect for the treatment of TCH.

Published: October 2020

In this work, the natural and modified carnauba powder from the addition of bentonite was evaluated for the adsorption of Cu(II) ions in synthetic solution. The results showed that the carnauba powder treated with bentonite (CPTB) showed a better percentage of removal of Cu(II) ions when compared to natural carnauba powder (NCP). The best results for both adsorbents were obtained with pH 5. The adsorption kinetics was governed by the pseudo-second-order model for both bioadsorbents studied. While the isothermal behavior was governed by the Langmuir model and showed that the adsorption capacity of the CPTB for Cu(II) was 21.98 mg·g−1. The interaction of the metal and CPTB was also investigated by means of thermodynamic parameters showing that the adsorption process is not spontaneous, although the values of ΔG° decrease with the increase in temperature from 20 to 40 °C and endothermic causing an increase in the degree of disorder at the solid/liquid interface. The results showed that the CPTB is a material with potential adsorbent for the removal of copper ions.
Glioblastoma Multiforme and its Cell Interruption
Authors: Bhattacharya Sankha
Published: October 2020

Glioblastoma (GBM) is a fatal type of brain cancer or primary glial neoplasm, mostly
targeting aged populations. The average survival is only 15 months from the date of occurrence. It
is often observed that, the invasive nature of the tumour is the main reason for poor prognosis and
strong recurrence of GBM in patients even after prescribed treatments. Despite all types of therapies,
it is necessary to understand the various molecular mechanisms and signalling pathways to
identify targets for GBM treatment. This compilation is specifically designed to discuss Wnt signalling
and Hedgehog-GLI1 pathways, which have positive and negative regulation against GBM.
The recent research finding associated with different signalling pathways for GBM has also been
discussed within this article.

Authors: Di Bari Flavia , Vita Roberto , Marini Herbert , Borrielli Irene , Lo Re Carmela , Panebianco Vincenzo , Benvenga Salvatore
Published: October 2020

Introduction:

Primary hyperparathyroidism (PHPT) is rare in pregnancy. PHPT and hypercalcemia
are associated with negative maternofetal outcomes. Therefore, an early diagnosis and
adequate treatment are essential.

Case Presentation:

We described the case of a pregnant woman complaining of nausea, vomiting
and weight loss. Diagnosis of gestational PHPT (GPHPT) was made based on elevated serum calcium
and parathyroid hormone levels (3.4 mmol/L and 41.6 pmol/L). Neck ultrasound documented a
nodule suggestive of enlarged parathyroid, whereas the abdomen ultrasound revealed renal microlithiasis.
Conservative treatment was started with oral hydration and a low-calcium diet. Clinical
and biochemical monitoring was weekly and multidisciplinary. Despite our suggestion, the patient
refused parathyroidectomy in the second trimester. Additional intravenous fluid rehydration
from the 15th to the 25th week of gestation ameliorated the symptoms rapidly, and reduced calcium
levels progressively from the 23rd week. At week 40, the woman gave birth to a healthy girl. At
month 8 postpartum, calcemia and PTH were still elevated, and accompanied by osteoporosis and
nephrocalcinosis. Surgery was accepted, and a parathyroid adenoma was removed.

Conclusion:

In the absence of guidelines for GPHPT management, its treatment should be individualized.
In our case, despite high calcium levels, conservative treatment with strict monitoring led
to a positive outcome of pregnancy.

Published: October 2020

Los objetivos de México de reducir las emisiones de dióxido de carbono y de mejorar la Eficiencia Energética (EE) no pueden lograrse si no se hacen estimaciones de EE. Sin embargo, dada la falta de datos por estado, no hay indicadores por regiones o estados. Utilizando un modelo de Frontera de Producción Estocástica este artículo ofrece una estimación de EE para 29 estados e identifica determinantes de ineficiencia energética. Las conclusiones principales son tres: primero, la mayoría de los estados han mejorado su EE, excepto Jalisco, Baja California y Veracruz; segundo, se identificaron tres variables como determinantes de ineficiencia energética que son: densidad de población, potencial de mercado y alta presencia de la industria de materiales; tercero, el consumo de energía no disminuye con aumentos en el precio. La principal limitación es que, dada la disponibilidad de información, las estimaciones sólo incluyen a la electricidad como fuente primaria de energía.
On the Interaction among Economic Growth, Energy-Electricity Consumption, CO2 Emissions, and Urbanization in Latin America

Published: October 2020

Esta investigación tiene como objetivo estudiar las interacciones dinámicas de largo plazo entre los cambios en las emisiones de CO2, el crecimiento económico, los cambios en el uso de energía y electricidad, y los cambios de la población rural a la urbana en América Latina (AL) durante el período 1990-2014. Un enfoque de datos panel VEC (VAR) con datos del Banco Mundial muestra que la primera y segunda diferencias de los logaritmos de la proporción de la población urbana con respecto a la población total explican: emisiones de CO2, PIB per cápita, consumo de energía, electricidad per cápita y el proceso de urbanización. Además, las emisiones de CO2 se cointegran con la primera diferencia con el logaritmo de la proporción de la población urbana. Los resultados empíricos no sugieren evidencia de la existencia de una curva ambiental de Kuznets. Tampoco es posible generalizar la naturaleza de las relaciones de crecimiento económico-consumo de energía-urbanización y emisiones de CO2 en diferentes latitudes. Una delimitación de este documento es la disponibilidad limitada de datos para varios países de AL, lo cual restringe el alcance del análisis econométrico

La interacción entre el medio ambiente, el crecimiento y el desarrollo económico, ha sido un tema de interés creciente para la investigación académica. El presente artículo, propone un modelo teórico de decisión endógena de la eficiencia en la empresa, para comprender la interrelación entre energía, producción, y crecimiento. Se revisan la literatura y la evidencia empírica de las variables consideradas. Se asume que agentes económicos motivados por la maximización de sus utilidades y beneficios, toman decisiones de gestión desde una función CES, para lograr un mix eficiente de producción. El modelo propuesto y la hipótesis de maximización de la utilidad derivada del capital humano, se ajusta con la evidencia de las economías del sudeste asiático (1950-1990).Más investigación es necesaria, acerca de la función de gestión de producción CES, y la relación entre energía y crecimiento. Una limitación, es la carencia de un formato inclusivo de las variables macro y microeconómicas, que influyen el crecimiento económico.Finalmente, la omisión del rol de la gestión, tiene un impacto sesgado en las recomendaciones de política respecto de la interacción energía - crecimiento.Palabras claves: Racionalidad acotada, Globalización, Capital Humano, Organización de la empresa, gestión, crecimiento económico.

Published: October 2020

Background

Medication adherence is important in managing the progression of chronic diseases. A promising approach to reduce cognitive burden when measuring medication adherence lies in the use of computer‐adaptive tests (CATs) or in the development of shorter patient-reported outcome measures (PROMs). However, the lack of an item bank currently hampers this progress.

Objective

We aim to develop an item bank to measure general medication adherence.

Methods

Using the preferred reporting items for systematic review and meta-analysis (PRISMA), articles published before October 2019 were retrieved from PubMed, Embase, CINAHL, the Cochrane Library, and Web of Science. Items from existing PROMs were classified and selected (“binned” and “winnowed”) according to standards published by the Patient-Reported Outcomes Measurement Information System (PROMIS) Cooperative Group.

Results

A total of 126 unique PROMs were identified from 213 studies in 48 countries. Items from the literature review (47 PROMs with 579 items for which permission has been obtained) underwent binning and winnowing. This resulted in 421 candidate items (77 extent of adherence and 344 reasons for adherence).

Conclusions

We developed an item bank for measuring general medication adherence using items from validated PROMs. This will allow researchers to create new PROMs from selected items and provide the foundation to develop CATs.
Associations Between COVID-19 Misinformation Exposure and Belief With COVID-19 Knowledge and Preventive Behaviors: Cross-Sectional Online Study
Authors: Lee Jung Jae , Kang Kyung-Ah , Wang Man Ping , Zhao Sheng Zhi , Wong Janet Yuen Ha , O'Connor Siobhan , Yang Sook Ching , Shin Sunhwa
Published: October 2020

Background

Online misinformation proliferation during the COVID-19 pandemic has become a major public health concern.

Objective

We aimed to assess the prevalence of COVID-19 misinformation exposure and beliefs, associated factors including psychological distress with misinformation exposure, and the associations between COVID-19 knowledge and number of preventive behaviors.

Methods

A cross-sectional online survey was conducted with 1049 South Korean adults in April 2020. Respondents were asked about receiving COVID-19 misinformation using 12 items identified by the World Health Organization. Logistic regression was used to compute adjusted odds ratios (aORs) for the association of receiving misinformation with sociodemographic characteristics, source of information, COVID-19 misinformation belief, and psychological distress, as well as the associations of COVID-19 misinformation belief with COVID-19 knowledge and the number of COVID-19 preventive behaviors among those who received the misinformation. All data were weighted according to the Korea census data in 2018.

Results

Overall, 67.78% (n=711) of respondents reported exposure to at least one COVID-19 misinformation item. Misinformation exposure was associated with younger age, higher education levels, and lower income. Sources of information associated with misinformation exposure were social networking services (aOR 1.67, 95% CI 1.20-2.32) and instant messaging (aOR 1.79, 1.27-2.51). Misinformation exposure was also associated with psychological distress including anxiety (aOR 1.80, 1.24-2.61), depressive (aOR 1.47, 1.09-2.00), and posttraumatic stress disorder symptoms (aOR 1.97, 1.42-2.73), as well as misinformation belief (aOR 7.33, 5.17-10.38). Misinformation belief was associated with poorer COVID-19 knowledge (high: aOR 0.62, 0.45-0.84) and fewer preventive behaviors (≥7 behaviors: aOR 0.54, 0.39-0.74).

Conclusions

COVID-19 misinformation exposure was associated with misinformation belief, while misinformation belief was associated with fewer preventive behaviors. Given the potential of misinformation to undermine global efforts in COVID-19 disease control, up-to-date public health strategies are required to counter the proliferation of misinformation.
Design Guidelines of a Computer-Based Intervention for Computer Vision Syndrome: Focus Group Study and Real-World Deployment (Preprint)
Authors: Hwang Youjin , Shin Donghoon , Eun Jinsu , Suh Bongwon , Lee Joonhwan
Published: October 2020

BACKGROUND

Prolonged time of computer use increases the prevalence of ocular problems, including eye strain, tired eyes, irritation, redness, blurred vision, and double vision, which are collectively referred to as computer vision syndrome (CVS). Approximately 70% of computer users have vision-related problems. For these reasons, properly designed interventions for users with CVS are required. To design an effective screen intervention for preventing or improving CVS, we must understand the effective interfaces of computer-based interventions.

OBJECTIVE

In this study, we aimed to explore the interface elements of computer-based interventions for CVS to set design guidelines based on the pros and cons of each interface element.

METHODS

We conducted an iterative user study to achieve our research objective. First, we conducted a workshop to evaluate the overall interface elements that were included in previous systems for CVS (n=7). Through the workshop, participants evaluated existing interface elements. Based on the evaluation results, we eliminated the elements that negatively affect intervention outcomes. Second, we designed our prototype system LiquidEye that includes multiple interface options (n=11). Interface options included interface elements that were positively evaluated in the workshop study. Lastly, we deployed LiquidEye in the real world to see how the included elements affected the intervention outcomes. Participants used LiquidEye for 14 days, and during this period, we collected participants’ daily logs (n=680). Additionally, we conducted prestudy and poststudy surveys, and poststudy interviews to explore how each interface element affects participation in the system.

RESULTS

User data logs collected from the 14 days of deployment were analyzed with multiple regression analysis to explore the interface elements affecting user participation in the intervention (LiquidEye). Statistically significant elements were the instruction page of the eye resting strategy (P=.01), goal setting of the resting period (P=.009), compliment feedback after completing resting (P<.001), a mid-size popup window (P=.02), and CVS symptom-like effects (P=.004).

CONCLUSIONS

Based on the study results, we suggested design implications to consider when designing computer-based interventions for CVS. The sophisticated design of the customization interface can make it possible for users to use the system more interactively, which can result in higher engagement in managing eye conditions. There are important technical challenges that still need to be addressed, but given the fact that this study was able to clarify the various factors related to computer-based interventions, the findings are expected to contribute greatly to the research of various computer-based intervention designs in the future.
Fostering compliance with physical distancing by interactive feedback in the context of the COVID-19 pandemic: evidence from the CorDis study. (Preprint)
Authors: Kaiser Tim , Lück Inga , Feldmann Matthias , Hamm Alfons , Brakemeier Eva-Lotta
Published: October 2020

BACKGROUND

To slow down the spread of COVID-19, the observance of basic hygiene measures, and physical distancing is recommended. Initial findings suggest that physical distancing in particular can prevent the spread of COVID-19. Attitudes towards these measures are influenced by many factors and are likely to play an important role in their compliance. Information on the effectiveness and significance of the measures could have an influence on this, but there is empirical evidence that this influence depends on the way of presentation.

OBJECTIVE

To investigate how information to prevent the spread of infectious diseases should be presented in order to increase willingness to comply with preventive measures.

METHODS

In a preregistered online experiment, 817 subjects were presented with either interactively controllable graphics on the spread of COVID-19 and information that enable them to recognize how much the spread of COVID-19 is reduced by physical distancing (experimental group) or text-based information about quantitative evidence (control group). It was hypothesized that participants receiving interactive information on the prevention of COVID-19 infections show a significantly higher willingness to comply with future containment measures than participants reading the text-based information. Explorative analyses were conducted to examine whether other factors influence compliance.

RESULTS

As predicted, we found a small effect (d = 0.22) for the tested intervention. In the exploratory analysis, the only additional significant predictor of change in compliance was health-related anxiety, but the effect was trivial.

CONCLUSIONS

When presented interactively, information on how the own behavior can help prevent infectious diseases can lead to slightly stronger changes in attitude towards behavioral prevention measures than just text-based information. Given the scalability of this simple internet-based intervention, it could play a role in fostering compliance during a pandemic within universal prevention strategies. Future work on the predictive validity of self-reported compliance and the real-world effects on the intervention is needed.

PRESERVATION POTENTIAL OF COMBINATION OF CLOVE AND LEMON BASIL ESSENTIAL OILS ON FRESH CHICKEN MEAT
Authors: Hartanti Dwi , Septiyaningrum Nur Annisa , Hamad Alwani
Published: October 2020

Clove and lemon basil are widely used in Indonesian culinary and known for their antimicrobial properties. This study was designed to identify the chemical constituents of individual clove and lemon basil essential oils and evaluate the effects of their combinations for the preservation of chicken meats. The essential oils were obtained from a steam and water distillation method and their chemical constituents were analyzed with Gas Chromatography-Mass Spectrometer (GC-MS). Their potential preservation effect was evaluated by observing the physical characters of the meats and the reduction of the microbial growth on the meats during 15 days of refrigerated storage. The major constituents of clove essential oil were eugenol, β-caryophyllene, and α-humulene, while those of lemon basil were estragole, linalool, E-citral, and Z-citral. The combination of clove and lemon basil essential oils, particularly at ratios of 1:1 and 2:0.2% v/v, capable of delaying the changes of physical characters of the meats until the final day of storage. Those two ratios showed the best reduction in the microbial growth in day 3 and 9, respectively. This preservation potential might be related to the high proportion of eugenol and citrals in both essential oils.

Published: October 2020

The north coast of Central Java is one of the most vulnerable regions to climate change in Indonesia. Various activity in coastal area also leads to the growing of informal sector that closely related to the growing number of poor people in coastal area. Therefore, the loss of livelihood triggers the awareness of stakeholder to help people through Community-based Adaptation (CBA) in Semarang coastal area. This paper aims to elaborate on the importance of networking aspect in CBA that works in Semarang Coastal Area. Scope area of this research is Tapak Village which regarded as a pilot area of CBA implementation in Semarang. Stakeholders mapping and social network analysis was used to visualizing the community interaction in their adaptation measures. The purposive sample in interviewing CBA stakeholders is used to support the stakeholder analysis using Gephi 0.9 software. The finding shows that the existence of networks between the community and the relevant stakeholders such as NGO and local government also became one of the supporting factors for the sustainability of community-based adaptation approach in coastal areas of Semarang City.

Yogyakarta is one of city in Indonesia which experience urban agglomeration called by Yogyakarta Urbanized Area (YUA). In this paper, identified the characters of each part of YUA by examining its urban form unit. This paper assesses the characteristics of urban forms distributed within YUA. Quantitative measurements were proposed for classifying the urban form typologies. Density, diversity, and accessibility were used to represent the urban form characteristic., the typologies are classified into three groups which are low compact, middle compact, and high compact. The result shows that the majority areas in YUA are grouped into middle compact typology where most of them are located in the city of Yogyakarta administrative area. Meanwhile, the areas, categorized as low compact typology, are in the hinterland area of Yogyakarta. High compact typology are concentrated in the centre of YUA where it has the highest activity concentration for the whole urban structure context. This study discovers that characterizing the urban growth patterns using quantitative method can distinguish urban form. At the end, this paper provides an important note about the distribution of urban form typology in the agglomeration area and, in the future, can be used to design urban policies, especially in the utilization of urban space.

Remotely sensed data and habitat model approach were employed to evaluate the present of oceanographic aspect in the Bigeye tuna's potential fishing zone (PFZ) at a profundity of 155 m. Vessel monitoring system was employed to acquire the angling vessels for Bigeye tuna from January through December, 2015-2016. Daily data of sub-surface temperature (Sub_ST), sub-surface chlorophyll-a (Sub_SC), and sub-surface salinity (Sub_SS) were downloaded from INDESO Project website. Vessel monitoring system and environmental data were employed for maximum entropy (maxent) model development. The model predictive achievement was then estimated applying the area under the curve (AUC) value. Maxent model results (AUC>0.745) exhibited its probable to understand the Bigeye tuna's spatial dispersion on the specific sub-surface. In addition, the results also showed Sub_ST (43,1%) was the most affective aspect in the Bigeye tuna dispersion, pursued by Sub_SC (35,2%) and Sub_SS (21,6%).

From 2014 to 2016, the number of prevalence of Dengue Hemorrhagic Fever (DHF) and deaths associated with DHF in Indonesia increased. DHF fatal cases were also reported from three administrative units in the Special Region of Yogyakarta, namely Bantul Regency, Gunungkidul Regency, and Yogyakarta City. Two related deaths in Purwosari, a district in Gunungkidul, raised the status of DHF to an outbreak. This study was designed to characterize the spread pattern of DHF in its endemic areas in Purwosari District using the retrospective method, anamnesis, in-depth interviews, Geographic Information System (GIS), and environmental analysis. The kernel density estimation revealed that in 2011-2017, DHF was concentrated in four villages, namely Giriasih, Giricahyo, Giritirto, and Giripurwo. There was a correlation between DHF incidents and physical geographical features of these villages, including proximity to water sources, high vegetation density, elevation, humidity, and rainfall, which created habitats for mosquito growth. A high incidence of DHF has been observed in children (50.8%) and students (57.4%), with most cases (78.7%) showing typical symptoms of the disease. A few of the 61 cases in the district developed into dengue shock syndrome (DSS) and led to death (4.9%), mainly because the public was unable to recognize the warning signs of DHF early and had limited knowledge of required management therapy. Moreover, the preventive or precautionary measures known as the 3M-Plus were not fully implemented yet.

It has been more than a decade after 5.9 SR earthquakes hit one of the most destructed area Tembi Hamlet, Bantul District, Yogyakarta Province. Amidst the wreaking havoc, the area gained its resilient in no time. This research, aimed to 1) explore what are the factors influential towards local resilient, especially micro-small-medium enterprises; and 2) analyze strategies to tackle disaster. It employed mix method, while the key questions were developed using “Sustainable Livelihood Approach” by DFID, geared with “Pentagram Asset” mapping for each spatial and temporal unit. The result revealed that 1) the micro-small-medium enterprises in urban area are resilient towards earthquake due to fair physical, natural and financial assets management and abundant social, human and political assets. These assets have created enabling environment towards behavioral change of urban society; 2) Despite various livelihood strategies existed in urban areas, the research highlighted three types of livelihood strategies within disaster risk management perspective, i.e. survival (disaster), consolidation by no-change plan mechanism and accumulation strategies by change plan mechanism (post disaster). Critically, pentagram assessment is able to identify feasible local assets and activities, however it left the policy, institution, interaction and multi sector aspects from the spotlight. Herewith, the research proposes evaluation scan to rethinking sustainable livelihood approach within disaster risk management by adding these aspects into the observation. It also revealed that local autonomous initiatives to extend urban based economic activities and supported by abundant political interest play pivotal role in disaster management at developing countries.

Thermal front has been widely used as a parameter for determining ﬁshing zones. Tis study aimed to  determine  the  thermal  front  distribution  and  to  analyze  its  association  with  the  Bali  Sardinella  ﬁshing zones  in  the  Bali  Strait.  Termal  front  generated  using  sea  surface  temperature  (SST)  from  Aqua  MODIS imagery. Meanwhile, the ﬁshing point data of Bali Sardinella were collected to validate our analysis results. Te data were analyzed into Spatio-temporal information. Te main facts that stand out are that the thermal front  was  predominantly  found  in  the  peak  of  ﬁrst (April)  and  second  (September)  transitional  season, which was the peak season for the thermal front to occur in a year. Te least of the thermal front occurred in the  South-west  monsoon.  Te  linear  relationship  was found  when  the  peak  of  thermal  front  occurrence compared to the number of catch yields. Based on matching distance analysis, the maximum distance used (twenty  kilometres  buﬀer)  show  36  matching  points from  101  data  compared  or  at  range  35.6%.  In conclusion, there is a linear relationship between the thermal front parameter and catch yield. It is still used to predict the ﬁshing zone, even though the correlation is not signiﬁcantly found.
Study on the possibility of predicting the onset and rainfall of wet season in Yogyakarta Special Province, Indonesia
Authors: Kirono Dewi Galuh Condro , Salmon Budi
Published: October 2020

Indonesian region frequently experiences a prolonged drought and/or flood hazard One of the key factors that often triggers these Awards is the occurrence of seasonal rainfall anomaly. To minimize the possible impact of such extreme event, it is necessary to develop a model that can be applied to predict the wet season onset and wet season rainfall. This paper is a preliminary effort on this mailer. As a pilot study, Yogyakarta Special Province (DIY) has been selected for this purpose. In particular; the analysis is emphasized on the Adisucipto airport station, Yogyakarta, as it is one of the first-class climatological station in DIY which has a very good and long data required for such intention. Detail objectives of this study are to address the following three questions: (1) is it possible to predict wet season onset in Adisucipto airport station using local and regional atmospheric indicators? (2) if it is possible and the model(s) have been developed, can the model(s) be applied for predicting the onset of wet season in other parts of DIY and its surround? (3) does an early or late onset of wet season provide any indication to subsequent rainfall during the wet season? To achieve these objectives, the study requires several types of data including daily rainfall data, monthly air pressure data, Southern Oscillation Index (SO!) and Sea Surface Temperature data. Most of the data cover the period of 1976 to 2001. Methods that have been applied to meet the goals are statistical descriptive and simple liner regression analysis. The results suggest that: (I) wet season onset time in Yogyakarta can be predicted using both local and regional atmospheric factors. namely August and September SOI, and air pressure index at Adisucipto airport station in June. July and August; (2) models that have been developed for Adisucipto airport station are modest enough to be applied for predicting the onset of wet season at other location; (3) the onset of wet season cannot be used as an indicator to estimate rainfall in wet season itself.
