Published: December 2020

Background

The prevalence of overweight and obesity in women has increased significantly over the last few decades in Bangladesh, a rapidly urbanising developing country. However, little is known regarding the association between the interaction of the place of residence and household wealth with overweight and obesity, particularly in women from developing countries.

Objective

The objective of this study is to find the association between the interaction of the place of residence and wealth with overweight and obesity among Bangladeshi women.

Methods

This study utilised data from the four Bangladesh Demographic Health Surveys conducted in 2004, 2007, 2011 and 2014 with a total of 54337 women aged 15–49 years. Multivariate logistic regression was used for the analyses.

Results

The prevalence of overweight and obesity among women aged 15–49 years in Bangladesh has considerably increased from 9.96% in 2004 to 24.43% in 2014. The interaction between wealth and place of residence has been found to be associated with obesity. Urban wealthy and richest women were 4.23 (OR: 4.23, 95% CI: 1.25–14.34) and 5.99 (OR: 5.99, 95% CI: 1.91–18.74) times more likely to be obese compared to their rural counterparts in the period 2004. Urban richest were 2.94 times (OR: 2.94, 95% CI: 1.20–7.24) more likely to be obese against their rural counterparts for the survey year 2014.

Conclusions

The place of residence is not associated with obesity, but its interaction with wealth is significant.
Mutational networks of escape from transmitted HIV-1 infection
Authors: Akand Elma H. , Maher Stephen J. , Murray John M.
Published: December 2020

Human immunodeficiency virus (HIV) is subject to immune selective pressure soon after it establishes infection at the founder stage. As an individual progresses from the founder to chronic stage of infection, immune pressure forces a history of mutations that are embedded in envelope sequences. Determining this pathway of coevolving mutations can assist in understanding what is different with the founder virus and the essential pathways it takes to maintain infection. We have combined operations research and bioinformatics methods to extract key networks of mutations that differentiate founder and chronic stages for 156 subtype B and 107 subtype C envelope (gp160) sequences. The chronic networks for both subtypes revealed strikingly different hub-and-spoke topologies compared to the less structured transmission networks. This suggests that the hub nodes are impacted by the immune response and the resulting loss of fitness is compensated by mutations at the spoke positions. The major hubs in the chronic C network occur at positions 12, 137 (within the N136 glycan), and 822, and at position 306 for subtype B. While both founder networks had a more heterogeneous connected network structure, interestingly founder B subnetworks around positions 640 and 837 preferentially contained CD4 and coreceptor binding domains. Finally, we observed a differential effect of glycosylation between founder and chronic subtype B where the latter had mutational pathways significantly driven by N-glycosylation. Our study provides insights into the mutational pathways HIV takes to evade the immune response, and presents features more likely to establish founder infection, valuable for effective vaccine design.
Preparing for the interviewing process during Coronavirus disease-19 pandemic: Virtual interviewing experiences of applicants and interviewers, a systematic review
Authors: Chandratre Sonal , Soman Aamod
Published: December 2020

Purpose

Coronavirus disease-19 (COVID-19) has forced upon all academic institutions to conduct virtual interviewing (VI) instead of face-to-face interviewing (FTFI) this interviewing cycle. The purpose of this systematic review was to understand the process of VI, its effectiveness as an alternative to FTFI, and the experiences of applicants and institutions with VI. We also share best practice strategies for applicants and institutions in VI preparation.

Method

PubMed/MEDLINE, Cochrane Library of Systematic Reviews, Web of Science Core Collection, Scopus and CINAHL databases were searched through May 2020. Articles in English evaluating the effectiveness of VI were included, without applying any date limits. Two reviewers selected articles and extracted data.

Results

Of the 934 articles screened, 22 articles underwent full-text article analysis to include 15 studies. There were 4 studies that reported the use of VI as a screening tool. 11 studies completely replaced FTFI with VI. Most applicants could appropriately convey themselves through VI. Most applicants and interviewing programs expressed reservations about VI’s use as an alternative to FTFI.

Conclusion

There is dearth of evidence supporting the efficacy of VI. There is an opportunity for potential research at multi-institutional level to gain better understanding of the efficacy of VI. The knowledge obtained from this systematic review has the potential of helping applicants and institutions in preparing for VI process. Additionally, authors propose supportive strategies to help prepare applicants and institutions for VI.

Published: December 2020

The Ecuadorianpáramo, a high altitude tundra-like ecosystem, is a unique source of various ecosystem services and distinct biodiversity. Anthropogenic activities are associated with its fragmentation, which alters ecological factors and directly threatens resident species.Vaccinium floribundumKunth., commonly known as Andean blueberry ormortiño, is a wild shrub endemic to the Andean region and highly valued in Ecuador for its berries, which are widely used in food preparations and hold an important cultural value. Since it is a wild species,mortiñocould be vulnerable to environmental changes, resulting in a reduction of the size and distribution of its populations. To evaluate the extent of these effects on themortiñopopulations, we assessed the genetic diversity and population structure of the species along the Ecuadorian highlands. We designed and developed a set of 30 species-specific SSR (simple sequence repeats) markers and used 16 of these to characterize 100mortiñoindividuals from 27 collection sites. Our results revealed a high degree of genetic diversity (HE= 0.73) for the Ecuadorianmortiño, and a population structure analyses suggested the existence of distinct genetic clusters present in the northern, central and southern highlands. A fourth, clearly differentiated cluster was also found and included individuals from locations at higher elevations. We suggest that the population structure of the species could be explained by an isolation-by-distance model and can be associated with the geological history of the Andean region. Our results suggest that elevation could also be a key factor in the differentiation ofmortiñopopulations. This study provides an extensive overview of the species across its distribution range in Ecuador, contributing to a better understanding of its conservation status. These results can assist in the development of conservation programs for this valuable biological and cultural resource and for thepáramoecosystem as a whole.

Authors: Bi Rujia , Zhou Can , Jiao Yan
Published: December 2020

Tagging studies have been widely conducted to investigate the movement pattern of wild fish populations. In this study, we present a set of length-based, age-structured Bayesian hierarchical models to explore variabilities and uncertainties in modeling tag-recovery data. These models fully incorporate uncertainties in age classifications of tagged fish based on length and uncertainties in estimated population structure. Results of a tagging experiment conducted by the Ontario Ministry of Natural Resources and Forestry (OMNRF) on yellow perch in Lake Erie was analyzed as a case study. A total of 13,694 yellow perch were tagged with PIT tags from 2009 to 2015; 322 of these were recaptured in the Ontario commercial gillnet fishery and recorded by OMNRF personnel. Different movement configurations modeling the tag-recovery data were compared, and all configurations revealed that yellow perch individuals in the western basin (MU1) exhibited relatively strong site fidelity, and individuals from the central basin (MU2 and MU3) moved within this basin, but their movements to the western basin (MU1) appeared small. Model with random effects of year and age on movement had the best performance, indicating variations in movement of yellow perch across the lake among years and age classes. This kind of model is applicable to other tagging studies to explore temporal and age-class variations while incorporating uncertainties in age classification.
Impact of class-level labelling change on prescriptions of antidepressants for adolescents: An interrupted time-series study using a health insurance claims database in Japan, 2005-2013
Authors: Ogino Yumiko , Schmidt Axel Jeremias
Published: December 2020

Background

In October 2007, the Japanese Health Authority directed that precautions be added to antidepressants (ADs) labelling regarding suicide risk among young people.

This study evaluates the impact of the labelling change on AD prescriptions and Japanese adolescent suicide rates.

Methods

We compared AD prescription rates per 100,000 population as a primary outcome. The intervention group comprised adolescents (10–24 years), while the control group comprised adults (25–64 years). We defined the pre-intervention period as January 2005 to October 2007 and post-intervention as November 2007 to February 2013. Monthly prescription rate data from a commercial claims database were triangulated with annual suicide rates in Japan. We performed segmented regression analysis for the prescription rates, using a quasi-Poisson model, and tested for level and trend changes.

Results

The commercial claims database included 152,686 adolescents and 195,251 adults during the pre-intervention period and 846,367 adolescents and 1,352,453 adults during post-intervention. Post-intervention, the overall AD prescription rates decreased only in adult males (-95.8 prescription per 100,000) but increased in all other groups. The mean annual suicide rate increased in adolescent males (+1.5 suicides per 100,000) but decreased in all other groups. Overall, the upward trend became moderate or inverse in all groups post-intervention but with a large difference between males and females. The suicide rates rose slightly in adolescents but began declining in adults a year post-intervention. In females, changes in level, trend, and suicide rates were very small in both adolescents and adults.

Conclusions

Contrary to expectations, the mean prescription rates only decreased in adult males, but not in adolescents, regardless of gender. Downward level and trend change were clearly observed in adult males but not in adolescents, the original target of the updated warning. There were no clear temporal associations between suicide rates and the labelling change in either group.

Authors: Baumann-Vogel Heide , Hor Hyun , Poryazova Rositsa , Valko Philipp , Werth Esther , Baumann Christian R.
Published: December 2020

This retrospective single-center polysomnography-based study was designed to assess the frequency of REM sleep behavior disorder (RBD) in consecutive patients with Parkinsonism, including Parkinson disease, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration. We observed RBD in 77% of 540 Parkinson patients, with rising frequency at higher age and regardless of sex, in >89% of 89 patients with dementia with Lewy bodies or multiple system atrophy, and in <15% of 42 patients with progressive supranuclear palsy or corticobasal degeneration. Thus, the prevalence of RBD in sporadic Parkinson disease might be higher than previously assumed, particularly in elderly patients.

Published: December 2020

The present study aimed to investigate the incidence of hepatocellular carcinoma (HCC) and factors related to HCC occurrence after direct-acting antiviral (DAA) treatment in the Fukushima Liver Academic Group (FLAG). We conducted a multicenter retrospective cohort study of 1068 patients without cirrhosis (NC) or with compensated liver cirrhosis (LC) who achieved a sustained virologic response (SVR). First, we compared the cumulative HCC incidence and survival rates in NC (n = 880) and LC (n = 188) patients without a history of HCC treatment. Second, we performed multivariate analysis of factors related to HCC occurrence after DAA treatment. Overall, the average age was 65 years, and the male/female ratio was 511/557. Thirty-nine (4%) patients developed HCC. The cumulative 4-year HCC incidence and survival rates were 3.0% and 99.8% in NC patients and 11.5% and 98.5% in LC patients, respectively. The independent factors affecting HCC occurrence identified by multivariate analysis were the serum albumin (ALB) level before SVR for NC patients and the ALBI score, platelet count, and diabetes before SVR for LC patients. The factors related to HCC occurrence differed between NC and LC patients. Careful surveillance of post-SVR patients with these risk factors is needed.

Authors: Jin Jing , Robeson Heather , Fagan Pebbles , Orloff Mohammed S.
Published: December 2020

Objective

The carcinogenesis role ofPARP1in lung cancer is still not clear. Analysis at allelic levels cannot fully explain the function ofPARP1on lung cancer. Our study aims to further explore the relation betweenPARP1haplotypes and lung cancer.

Materials and methods

DNA and RNA were extracted from non-small cell lung cancer (NSCLC) tumor and adjacent normal fresh frozen tissue. FivePARP1-SNPs were genotyped andPARP1-specific SNPs were imputed using IMPUTE and SHAPEIT software. The SNPs were subjected to allelic, haplotype and SNP-SNP interaction analyses. Correlation between SNPs and mRNA/protein expressions were performed.

Results

SNP imputation inferred the ungenotyped SNPs and increased the power for association analysis. Tumor tissue samples are more likely to carry rs1805414 (OR = 1.85; 95% CI: 1.12–3.06; P-value: 0.017) and rs1805404 (OR = 2.74; 95%CI 1.19–6.32; P-value: 0.015) compared to normal tissues. Our study is the first study to show that haplotypes comprising of 5 SNPs onPARP1(rs1136410, rs3219073, rs1805414, rs1805404, rs1805415) is able to differentiate the NSCLC tumor from normal tissues. Interaction between rs3219073, rs1805415, and rs1805414 were significantly associated with the NSCLC tumor with OR ranging from 3.61–6.75; 95%CI from 1.82 to 19.9; P-value<0.001.

Conclusion

PARP1haplotypes may serve as a better predictor in lung cancer development and prognosis compared to single alleles.
Synergies between urban heat island and heat waves in Seoul: The role of wind speed and land use characteristics
Authors: Ngarambe Jack , Nganyiyimana Jacques , Kim Inhan , Santamouris Mat , Yun Geun Young
Published: December 2020

The effects of heat waves (HW) are more pronounced in urban areas than in rural areas due to the additive effect of the urban heat island (UHI) phenomenon. However, the synergies between UHI and HW are still an open scientific question and have only been quantified for a few metropolitan cities. In the current study, we explore the synergies between UHI and HW in Seoul city. We consider summertime data from two non-consecutive years (i.e., 2012 and 2016) and ten automatic weather stations. Our results show that UHI is more intense during HW periods than non-heat wave (NHW) periods (i.e., normal summer background conditions), with a maximum UHI difference of 3.30°C and 4.50°C, between HW and NHW periods, in 2012 and 2016 respectively. Our results also show substantial variations in the synergies between UHI and HW due to land use characteristics and synoptic weather conditions; the synergies were relatively more intense in densely built areas and under low wind speed conditions. Our results contribute to our understanding of thermal risks posed by HW in urban areas and, subsequently, the health risks on urban populations. Moreover, they are of significant importance to emergency relief providers as a resource allocation guideline, for instance, regarding which areas and time of the day to prioritize during HW periods in Seoul.
Effects of cooperative games on enjoyment in physical education—How to increase positive experiences in students?
Authors: Engels Eliane Stephanie , Freund Philipp Alexander
Published: December 2020

Enjoyment is one of the most important factors for the maintenance of regular physical activity. The present study investigated if cooperative games in physical education classes (grades 6–9) can increase students’ enjoyment of physical activity. Data were collected in a quasi-experimental study employing a two-group design with repeated measures and randomization of classes to conditions. The total sample consisted of N = 285 students from regular schools in Germany aged 10 to 16 years (Mage = 12.67 years, SD = 1.10; 48.4% female). We found that cooperative games led to a higher perceived enjoyment in physical education classes (F(1) = 3.49, p = .063, ηp2 = .012), increased the feeling of how strong students felt related to each other (F(1) = 4.38, p = .037, ηp2 = .016), and facilitated feelings of perceived competence in physical education class (F(1) = 6.31, p = .013, ηp2 = .022). In addition, social relatedness and perceived competence partly mediated the effect of cooperative games on enjoyment. The findings indicate that systematically designed cooperative games can help foster enjoyment in physical education classes.

Published: December 2020

Plant-derived terpenoids are extensively used in perfume, food, cosmetic and pharmaceutical industries, and several attempts are being made to produce terpenes in heterologous hosts. Native hosts have evolved to accumulate large quantities of terpenes in specialized cells. However, heterologous cells lack the capacity needed to produce and store high amounts of non-native terpenes, leading to reduced growth and loss of volatile terpenes by evaporation. Here, we describe how to direct the sesquiterpene patchoulol production into cytoplasmic lipid droplets (LDs) in Physcomitrium patens (syn. Physcomitrella patens), by attaching patchoulol synthase (PTS) to proteins linked to plant LD biogenesis. Three different LD-proteins: Oleosin (PpOLE1), Lipid Droplet Associated Protein (AtLDAP1) and Seipin (PpSeipin325) were tested as anchors. Ectopic expression of PTS increased the number and size of LDs, implying an unknown mechanism between heterologous terpene production and LD biogenesis. The expression of PTS physically linked to Seipin increased the LD size and the retention of patchoulol in the cell. Overall, the expression of PTS was lower in the anchored mutants than in the control, but when normalized to the expression the production of patchoulol was higher in the seipin-linked mutants.

Published: December 2020

In this article, the fabrication and performance of supercapacitors prepared through electrochemical reduction applied at different voltage range from polyaniline/graphene oxide (PANi/GO) thin films, which are renewable materials with an excellent yield of energy conversion is reported. The PANi/GO thin film was reduced electrochemically with different potential windows, scan rate and number of cycles which was acquired using layer-by-layer (LBL) assembly method. The resultant electrodes displayed various specific capacitances after pre-reduction with different conditions.The influence of the electrochemical reduction was investigated by Raman spectroscopy and X-ray photoelectron spectroscopy for capacitance performance. The optimum conditions were explored for supercapacitor application and an elevated specific capacitance 2619 F cm-3 (areal capacitance 18.38 mF cm-2) at 1 mV s-1 obtaining the film reduced with applied potential of -0.87 to -0.5 V. This study could introduce the new possibilities for the improvement of the electrochemical reduction effects to the composite materials for high-performance supercapacitors.
Spectral and Biological Studies: Co(II), Ni(II), Cu(II), Zn(II) and Pd(II) Complexes of 5-Methyl-4-{(3-fluoro-4-methoxybenzylidiene)amino}-3-thiol-1,2,4-triazole

Published: December 2020

A series of metal-complexes of Co2+, Ni2+, Cu2+, Zn2+ and Pd2+ with new Schiff base named 5-methyl-4-((3-fluoro-4-methoxybenzylidiene)-amino)-3-thiol-s-triazole have been synthesized and characterized. Schiff base is formed by the condensation of 3-fluoro-4-methoxy-benzaldehyde and 4-amino-3-mercapto-5-methyl-1,2,4-triazoles (AMMT). After synthesis, Schiff base is characterized by IR and NMR techniques. Metal complexes are characterized by different techniques as IR, NMR, ESR, electronic and fluorescence. Elemental analysis and magnetic measurements of metal complexes have also been carried out. Using different techniques, tentative geometry for newly synthesized complexes have been proposed i.e. square planar for copper and palladium complexes and octahedral for rest of the metal complexes. The biological activities of all the metal complexes of this series are also examined.

Towards Cloud-supported Automotive Software Development and Test
Authors: Bergelt René , Englisch Norbert
Published: December 2020

The development of automotive software has been an evolving process for the last decades. As a result, the paradigm of software development which is independent of the target hardware platform has been adopted in almost all parts of the automotive industry. Deploying software to a hardware platform is now controlled by an enormous parameter set stored in a mapping configuration. This led to the creation of numerous vendor-specific tools for electronic control unit (ECU) development. While this approach simplifies and supports the re-usability of vehicle functions it also increases the complexity as well as the difficulty for integration tests and error localization. In this paper, we present a conceptual platform which allows to establish references between different development and test phase items in a developer-friendly way. It revolves around two self-developed tools supported by an extensive AUTOSAR knowledge base. The system creates inter-connectivity so that it becomes easier to locate the actual origin of a misbehavior or to find a test error manifestation in the actual end system for developers and testers alike.

Authors: Maximov Ivo , Schöneck Tobias , Weise Sebastian , Golder Markus
Published: December 2020

In dem Forschungsprojekt wird ein berührungsloses Direktantriebssystem für hochdynamische Bandförderer entwickelt. Die Förderkraft wird nach dem Prinzip der linearen Asynchronmaschine in den Gurt eingeleitet. Zur Umsetzung des Antriebs­prinzips muss der Gurt flächig eine Kupferstruktur, die den Sekundärteil der Asynchron­maschine darstellt, beinhalten. Die Herausforderungen bei der Auslegung dieser Struktur bestehen in der Berücksichtigung der elektrischen Anforderungen zur Umsetzung des Linearmotors einerseits und anderseits in der Berücksichtigung der mechanischen Anforderungen die während des Betriebs des Förderers auftreten. Im weiteren Projektverlauf wird das Antriebssystem um Condition-Monitoring-Funktionalitäten erweitert: Anhand der Statorströme wird die elektrodynamische Rückwirkung der Kupferstruktur im Gurt ausgewertet. Die gewonnenen Daten ermöglichen einen Rückschluss auf den Zustand der Kupferstruktur und gestatten somit eine Beurteilung des Verschleiß­zustandes des Motors und des Gurts. Ferner lässt sich der Bewegungszustand des Bandförderers bestimmen. Aus wirtschaftlichen Gründen soll sich der resultierende Bandförderer mit neu­artigem Antriebssystem durch kleine Umlenkradien, den Verzicht auf zusätzliche Zugträger sowie die Erreichung eines bestmöglichen motorischen Wirkungsgrades auszeichnen. Für diese Forschungsziele ist die Kupferstruktur, welche in den Gurt integriert wird, von herausragender Bedeutung. In diesem Beitrag wird das Ergebnis der Betrachtung der Kupferwerkstoffe dargestellt.

Published: December 2020

Many industry sectors benefit from the new opportunities additive manufacturing provides. Lightweight designs and integration of function are only two aspects. As there are no approaches present to insert additive manufacturing into the design of hoisting appliances though, we try to evaluate the room for improvement through experimental analysis. Additively manufactured synthetic drum-bodies fit for 8 mm wire ropes and containing different infill structures were tested for tensile strength. The cylindrical gyroid TPMS and straight spokes structures performed best with standardised tensile strengths of 17.53 and 16.40 kN/kg. Our findings indicate that additively manufactured rope drums can be a viable option for future hoisting appliances.
Analyse von Wirkungsgradverlusten in Kettenfördersystemen
Authors: Bona Marcus , Sumpf Jens , Golder Markus
Published: December 2020

Gerade in der heutigen Zeit, vor dem Hintergrund steigender globaler Erwärmung, rückt die Energieeffizienz elektrisch angetriebener technischer Systeme immer mehr in den Fokus. So auch im intralogistischen Materialtransport. Der Gesamtwirkungs­grad eines Stetigförderers, also das Verhältnis aus aufgewandter elektrischer Leistung und der Transportleistung, ist dabei von der Effizienz seiner zahlreichen Einzelkomponenten abhängig. Bereits durchgeführte Messungen zeigen, dass dabei vor allem dem Antriebs­system große Bedeutung beikommt. Die in Kettenförderern am häufigsten eingesetzten Antriebe sind Drehstrom-Asynchron-Getriebemotoren. Diese weisen in ihrem Nennlast­bereich zwar gute Wirkungsgrade von über 80% auf, werden im Großteil aller Fälle jedoch im unteren Lastbereich betrieben. Die oft viel zu groß ausgelegten Motoren arbeiten somit mit einem erheblich schlechteren Wirkungsgrad, was zu einem erhöhten Energieverbrauch führt. Der Beitrag befasst sich aus den genannten Gründen mit der Analyse von Wirkungs­gradverlusten am Beispiel von Kettenförderern und geht im Speziellen auf antriebs­technische Komponenten wie Motor, Frequenzumrichter und Getriebe ein. Das Ziel ist die Einordnung dieser Verluste in den Gesamtwirkungsgrad eines Förderers, der u. a. Reibungs- und Hubanteile enthält. Weiterhin werden Schlussfolgerungen und Empfehlungen zur Verbesserung der Effizienz von Kettenförderern diskutiert.

Authors: Katzer Norman , Bankwitz Hagen , Hübler Jörg
Published: December 2020

Die Zustandsüberwachung (Condition Monitoring) und die vorausschauende Wartung (Predicted Maintenance) gelten als Schlüsselinnovationen der Industrie 4.0. Im Zuge dessen arbeiten Forscher der Professur Intelligente Maschinensysteme an der Hochschule Mittweida an einem Kunststoffgleitlager, welches eine integrierte Sensorik besitzt, die dem Anwender die Überwachung von Betriebsdaten ermöglichen soll. Die aus einem elektrisch leitfähigen Kunststoff hergestellte Sensorik trägt dazu bei, dass in Echtzeit sowohl eine Aussage zur Lagertemperatur als auch zum Verschleißgrad des Lagers getroffen werden kann. Damit lassen sich Wartungsintervalle besser planen und ein prophylaktischer Austausch von noch gebrauchsfähigen Lagern kann vermieden und damit Kosten gesenkt werden. Dafür sind umfangreiche numerische Untersuchungen zum mechanischen, thermischen und elektrischen Verhalten der Sensorik bzw. des Gleitlagers mit Interaktion der Welle durchgeführt worden. Dies beinhaltet auch eine Auswahl möglicher Werkstoffe. Außerdem ist die Auswerteelektronik (Messwertverstärkung, Datenverarbeitung und Datenübermittlung) entsprechend den Anforderungen der Sensorik entwickelt wurden. In einem weiteren Schritt wurde ein Funktionsmuster des Kunststoffgleitlagers mittels FDM-Drucks hergestellt.

The purpose of this study was to determine the distribution of CO2 flux in Karimunjawa in the east monsoon.  The variables in this study were temperature; pH; salinity; DO; CO2 atm was measured using a CO2 meter; chlorophyll-a, phosphate, silicate were measured spectrophotometric method. Total Alkalinity / TA was measured using the titration method with the principle of changing pH; DIC (Dissolved Inorganic Carbon) was measured using CO2sys software. The partial pressure of seawater carbon dioxide calculated using formula: pCO2sea = 6.31T2 + 61,9 Chla2 – 365.85T – 94.41 Chl-a +5715.94, the partial pressure of atmospheric carbon dioxide calculated using formula: pCO2atm = xCO2atm (pb - pH2O).  The calculation of the estimated CO2 flux using the formula: Flux CO2 = Kh x kwa x (∆pCO2)  , if the CO2 flux has a positive value water acts as a CO2 source, and if it is negative, the waters act as a CO2 sink..  CO2 flux in Karimunjawa waters during east monsoon (represented by August 2018) showed that in Karimunjawa waters with normal pH 7.2-7.4 were dominated by bicarbonate ion HCO3-with an average value of  DIC 1847.24 µmol/kg dan TA 1912.51 µmol/kg.  The partial pressure of seawater CO2 is higher than the partial pressure of atmospheric CO2  this indicates that the role of Karimunjawa waters as a source of CO2 where there is release of carbon dioxide into the atmosphere with CO2 flux values ranging from 8.549 – 13.272 mmol m-2 day-1.  The variables that affect the flux of CO2 were the pCO2sea and ΔpCO2 with a very strong and positive correlation. These two variables were influenced by sea water temperature, salinity, chlorophyll-a, phosphate and silicate.

Since September 1, 2018, The Semarang City Government has diverted intercity bus stop within the province from Terboyo Terminal to Penggaron Terminal, resulting in an imbalance of movement and capacity of the Penggaron Terminal which causes queue of bus. Non-Poisson queue is a queue model in which the arrival and service distribution do not have a Poisson distribution or do not have an Exponential distribution. The study was conducted on buses entering the Penggaron Bus Station with the destination of Jepara, Kedungjati, Juwangi, Yogyakarta, Kudus/Pati/Lasem, Pekalongan/Tegal, and Purwokerto/Purworejo. The main goal of this project is to identify the queue model of Non-Poisson and calculate the measure of system performance using the GUI R. One of the programs in R that can create an interactive web-based GUI (Graphical User Interface) is R-Shiny. R-Shiny is a toolkit of R programs that can be used to create online programs. The distribution test obtained using the EasyFit program. The bus queue model of Jepara is (DAGUM/GEV/4):(GD/∞/∞), the queue model of Kedungjati is (GPD/ DAGUM/1):(GD/∞/∞), the queue model of Juwangi is (GEV/ GEV/1):(GD/∞/∞), the queue model of Yogyakarta is (DAGUM/ DAGUM/1) : (GD/∞/∞), the queue model of Kudus/Pati/Lasem is (DAGUM/GEV/1):(GD/∞/∞), the queue model of Pekalongan/Tegal is (GEV/DAGUM/1):(GD/∞/∞), and the queue model of Purwokerto/Purworejo is (GPD/DAGUM/1) : (GD/∞/∞).

A bond is investment instrument that is basically a debt investment. The profit gained in investing will be comparable with the risk. An investor must pay attention to the size of the risk in choosing bonds. Value at-Risk (VaR) is a risk measurement instruments for measure the maximum loss of asset or portfolio over a spesicif time interval for a given confidence level under normal market conditions. The purpose of this paper is to explain VaR measurement on bond portfolio using variance-covariance method and prove that method is valid to estimate VaR’s model using likelihood ratio. Variance covariance method was chosen because giving lower estimate potential volatility of asset or portfolio than historical simulation and Monte-Carlo simulation. This article use goverment bonds with code FR0053, FR0061, FR0073, FR0074 and portfolio combination. Normality test of return asset and portfolio are required before calculating VaR values. The result of this paper for confidence level 95% showed that bond portfolio FR0053 with FR0061 have a smaller value with VaR values 2,28% of the total market value. It was concluded that VaR bond portfolio are smaller than VaR single asset. Verification test estimate that VaR values using variance-covariance is valid at confidence level 95%.

Series such as financial and economic data do not always form a linear model, so a nonlinear model is needed. One of the popular nonlinear models is the Smooth Transition Autoregressive (STAR). STAR has two possible suitable transition function such as logistic and exponential that need to be test to find the appropriate transition function. The purpose of writing this thesis is to determine the LSTAR model, then use the model to predict the stock price of PT Bank Mandiri. This study uses the data of the weekly stock price of PT Bank Mandiri from the period of January 3, 2011 to December 24, 2018 as insample data and the period of January 1, 2019 to December 30, 2019 as outsample data. The research procedure begins with modeling the data with the Autoregressive (AR) process, testing the linearity of the data, modeling with LSTAR, forecasting, and finally evaluating the results of forecasting. Evaluating the results of the forecasting of the weekly share price of PT Bank Mandiri with the STAR model results in the best nonlinear model LSTAR (1,1). This model produces an highly accurate forecasting result with a value of symmetric Mean Square Error (sMAPE) to be 5.12%.Keywords: Nonlinear, Time Series, STAR, LSTAR.

The Consumer Price Index (CPI) provides information on changes in the average price of a group of fixed goods or services that are generally consumed by households within a certain period of time. The General CPI is formed from 7 sectors of public consumption expenditure groups. Because the formation of the consumer price index value is influenced by several sectors, the method that can be used is the transfer function method. The purpose of this study is to analyze the transfer function model so that the best model is produced to predict CPI in Purwokerto for the next several periods. In this study, general CPI modeling will be carried out based on the CPI value for the transportation services sector and the CPI for the Health sector in Purwokerto from January 2014 to July 2019 using the multi-input transfer function method. Based on the analysis, the best models are obtained, namely the multi-input transfer function model (2,0,0) (0,1,0) and the ARIMA noise series ([3], 0,0). The model has an Akaike's Information Criterion (AIC) value of 72.42021 and an sMAPE value of  2,351591 % which indicates that the model can be used for forecasting..Keywords: Consumer Price Index (CPI), Inflation,transfer function, AIC

Stock is a type of investment in financial assets that are many interested by investors. When investing, investors must calculate the expected return on stocks and notice risks that will occur. There are several methods can be used to measure the level of risk one of which is Value at Risk (VaR), but these method often doesn’t fulfill coherence as a risk measure because it doesn’t fulfill the nature of subadditivity. Therefore, the Expected Shortfall (ES) method is used to accommodate these weakness. Stock return data is time series data which has heteroscedasticity and heavy tailed, so time series models used to overcome the problem of heteroscedasticity is GARCH, while the theory for analyzing heavy tailed is Extreme Value Theory (EVT). In this study, there is also a leverage effect so used the asymmetric GARCH model with Glosten-Jagannathan-Runkle GARCH (GJR-GARCH) model and the EVT theory with Generalized Pareto Distribution (GPD) to calculate ES of the stock return from PT. Bank Central Asia Tbk for the period May 1, 2012-January 31, 2020. The best model chosen was ARIMA(1,0,1) GJR-GARCH(1,2). At the 95% confidence level, the risk obtained by investors using a combination of GJR-GARCH and GPD calculations for the next day is 0.7147% exceeding the VaR value of 0.6925%.

An international company operates an internal social media platform for communication and collaboration between employees. Employee satisfaction for the internal social network is regularly determined by the Net Promoter Score (NPS). The determined NPS represents the central performance indicator for the platform, which is communicated to the management. The values determined for the NPS were not satisfactory in the past. From an economic point of view, high investments were made for the integration of the platform. In addition, six-figure costs are incurred annually for operation and software licenses. Therefore, the improvement of the NPS is in the focus of all participants. Through user experience tracking and derivation of driver factors it is possible to find out which factors have the most significant influence on employee satisfaction in order to identify appropriate measures to improve the NPS.
