Authors: Saima Anwar  , Sana Akhtar  , Gra Badshah
Published: September 2022

The Evaluation and selection of Active Queue Management (AQM) methods are a complicated and challenging task. Improper AQM method can cause up-mark and network malfunctioning. To achieve satisfactory performance, various evaluation criteria need to be considered. In order to find the limitations of how the criteria are determined, there is a need to find out how their procedures change according to the evaluation and benchmarking process of AQM. This article focuses on the evaluation and benchmarking of Active Queue Management methods using Multi-Criteria Decision-Making (MCDM) techniques. MCDM uses different techniques to figure out the best alternative from multi-criteria and multi alternative conditions. Analytic Hierarchy Process (AHP) is a multi-criteria decision-making technique that is used to assign weights to criteria. Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used for ranking and selection of different alternatives by using distance measures. Whereas, FUZZY TOPSIS is used for criteria weightage and alternatives rating. MCDM calculation is performed on AQM methods and it is tried to discuss all these techniques. MCDM uses performance, overhead, and configuration criteria to evaluate and select the best AQM method that helps to determine solutions for future directions. The results show that Random Early Detection (RED) method got higher ranking score records as compared to other AQM methods.

Fracture Liaison Service (FLS) for secondary prevention of fragility fractures: the Italian IMPACT Project
Authors: Rossini Maurizio , Brutti Nicoletta , Adami Giovanni , Olivi Pietro
Published: September 2022

Osteoporosis and subsequent fragility fractures are an important public health issue since this is a common disease that leads to disability, and increased mortality, and therefore has a significant social and economic impact. Several studies have highlighted a dramatic diagnostic-therapeutic gap. A coordinated multidisciplinary system, known as the fracture liaison service (FLS) model, is the most appropriate approach for osteoporosis management and secondary prevention. Developed by the International Osteoporosis Foundation (IOF) through its Capture the Fracture campaign, the FLS model aims to avoid fragmentation of the care pathway by facilitating communication and coordination between primary care and medical specialists. The approach also involves patient identification and education, risk evaluation, the approval of treatments, and long-term follow up. The development of FLS programs has been strongly supported by the IOF. In Italy’s case, the primary recommendations made by the IOF in order to improve the management of patients with fragility fractures, and reverse the expected increase in the number of such fractures and their relative cost over the next 10 years, include the development of dedicated multidisciplinary care pathways, based on the FLS model. In order to make an effective contribution to the organizational needs in this regard, the primary objective of the IMPACT Project is to support the implementation and customization, in selected pilot centers in Italy, of an FLS model in line with the IOF recommendations and coherent with the Italian National Health Service (SNN), and to identify connection points with the territory, the activities of new healthcare professionals, and digital touchpoints in the care pathway.

Authors: Zeidan Amy , Salhi Brian , Backster Anika , Shelton Erica , Valente Alycia , Safdar Basmah , Wong Ambrose , Della Porta Alessandra , Lee Sangil , Schneberk Todd , Wilson Jason , Westgard Bjorn , Samuels-Kalow Margaret
Published: September 2022

Introduction: The application of structural competency and structural vulnerability to emergency medicine (EM) research has not been previously described despite EM researchers routinely engaging structurally vulnerable populations. The purpose of this study was to conduct a scoping review and consensus-building process to develop a structurally competent research approach and operational framework relevant to EM research.

Methods: We conducted a scoping review focused on structural competency and structural vulnerability. Results of the review informed the development of a structural competency research framework that was presented throughout a multi-step consensus process culminating in the 2021 Society for Academic Emergency Medicine Consensus Conference. Feedback to the framework was incorporated throughout the conference.

Results: The scoping review produced 291 articles with 123 articles relevant to EM research. All 123 articles underwent full-text review and data extraction following a standardized data extraction form. Most of the articles acknowledged or described structures that lead to inequities with a variety of methodological approaches used to operationalize structural competency and/or structural vulnerability. The framework developed aligned with components of the research process, drawing upon methodologies from studies included in the scoping review.

Conclusion: The framework developed provides a starting point for EM researchers seeking to understand, acknowledge, and incorporate structural competency into EM research. By incorporating components of the framework, researchers may enhance their ability to address social, historical, political, and economic forces that lead to health inequities, reframing drivers of inequities away from individual factors and focusing on structural factors.
Where Have All the FLOWERS Gone? A Multicenter Investigation of Frequent Users of Midwest Emergency Department Services During the COVID-19 Stay-at-home Orders
Authors: Levitin Howard , Jones Bruce , Lockhart Marie , Christopher Lloyd , Sharkey Meenal , Willette Paul , Kalnow Andrew
Published: September 2022

Introduction: In this study we aimed to determine the impact of the mandatory coronavirus disease 2019 (COVID-19) pandemic stay-at-home order on the proportional makeup of emergency department (ED) visits by frequent users and super users.

Methods: We conducted a secondary analysis of existing data using a multisite review of the medical records of 280,053 patients to measure the impact of the COVID-19 pandemic stay-at-home order on ED visits. The primary outcomes included analysis before and during the lockdown in determining ED use and unique characteristics of non-frequent, frequent, and super users of emergency services.

Results: During the mandatory COVID-19 stay-at-home order (lockdown), the percentage of frequent users increased from 7.8% (pre-lockdown) to 21.8%. Super users increased from 0.7% to 4.7%, while non-frequent users dropped from 91.5% to 73.4%. Frequent users comprised 23.7% of all visits (4% increase), while super user encounters (4.7%) increased by 53%. Patients who used Medicaid and Medicare increased by 39.3% and 4.6%, respectively, while those who were uninsured increased ED use by 190.3% during the lockdown.

Conclusion: When barriers to accessing healthcare are implemented as part of a broader measure to reduce the spread of an infectious agent, individuals reliant on these services are more likely to seek out the ED for their medical needs. Policymakers considering future pandemic planning should consider this finding to ensure that vital healthcare resources are allocated appropriately.
Economic Evaluation of Ultrasound-guided Central Venous Catheter Confirmation vs Chest Radiography in Critically Ill Patients: A Labor Cost Model
Authors: Ablordeppey Enyo , Koenig Adam , Barker Abigail , Hernandez Emily , Simkovich Suzanne , Krings James , Brown Derek , Griffey Richard
Published: September 2022

Introduction: Despite evidence suggesting that point-of-care ultrasound (POCUS) is faster and non-inferior for confirming position and excluding pneumothorax after central venous catheter (CVC) placement compared to traditional radiography, millions of chest radiographs (CXR) are performed annually for this purpose. Whether the use of POCUS results in cost savings compared to CXR is less clear but could represent a relative advantage in implementation efforts. Our objective in this study was to evaluate the labor cost difference for POCUS-guided vs CXR-guided CVC position confirmation practices.

Methods: We developed a model to evaluate the per patient difference in labor cost between POCUS-guided vs CXR-guided CVC confirmation at our local urban, tertiary academic institution. We used internal cost data from our institution to populate the variables in our model.

Results: The estimated labor cost per patient was $18.48 using CXR compared to $14.66 for POCUS, resulting in a net direct cost savings of $3.82 (21%) per patient using POCUS for CVC confirmation.

Conclusion: In this study comparing the labor costs of two approaches for CVC confirmation, the more efficient alternative (POCUS-guided) is not more expensive than traditional CXR. Performing an economic analysis framed in terms of labor costs and work efficiency may influence stakeholders and facilitate earlier adoption of POCUS for CVC confirmation.
Impact of Patient-Specific Aminoglycoside Monitoring for Treatment of Pediatric Cystic Fibrosis Pulmonary Exacerbations
Authors: Hemmann Brianna , Woods Elizabeth , Makhlouf Tanya , Gillette Chris , Perry Courtney , Subramanian Mary , Hanes Holly
Published: September 2022

OBJECTIVE

Aminoglycosides are frequently used for empiric and definitive treatment of cystic fibrosis (CF) pulmonary exacerbations. Various methods have been described for aminoglycoside therapeutic drug monitoring. The objective of this study is to evaluate the effect of patient-specific pharmacokinetic calculations for aminoglycosides used to treat CF pulmonary exacerbations.

METHODS

Ambidirectional cohort study of patients admitted to a children's hospital from June 1, 2018, through February 28, 2019, and June 1, 2019, through February 8, 2021. The primary outcome was the occurrence of dosing changes after analysis of initial serum concentrations in either group. Secondary outcomes included occurrence of nephrotoxicity, duration of antibiotics, and length of stay.

RESULTS

Twenty-four patients (75%) in the intervention group versus zero in the control group required dosing adjustments after initial analysis of serum concentrations were completed (p < 0.001). There was not a statistically significant between-group difference for duration of antibiotics in days (median, 14 vs 13.5; Z, 1.07; p = 0.29) or length of stay (median, 11 vs 11; Z, −0.31; p = 0.76). There was also not a statistically significant between-group difference in forced expiratory volume in one second (FEV1) change from admission to discharge (11.4% vs 13.9%; t, 0.61; Degrees of Freedom, 39; p = 0.55). Two patients (6.25%) in the intervention group experienced nephrotoxicity compared with zero patients in the control group (risk difference, 6.25%; 95% CI, −2.14 to 14.64; number needed to harm, 16).

CONCLUSIONS

Patient-specific pharmacokinetic monitoring led to significantly more dosing changes and was associated with similar patient outcomes as trough-only monitoring. Further studies are needed to identify methods to optimize aminoglycoside dosing and monitoring for these patients with the goal of reducing toxicities while maximizing efficacy.
Renal Impairment Associated With Trimethoprim-Sulfamethoxazole Use in the Pediatric Population
Authors: Sierra Caroline M. , Tran Yen , Oana Lacey , Bahjri Khaled
Published: September 2022

OBJECTIVE

Limited studies describe acute kidney injury (AKI) in children receiving trimethoprimsulfamethoxazole (SXT). The primary objective of this study was to describe AKI with SXT use in pediatric patients. Secondary objectives included describing the incidence of hyperkalemia and blood dyscrasias with SXT use.

METHODS

In this retrospective, single-center observational study, inpatient electronic medical records were reviewed for patients younger than 18 years of age who received at least 5 days of SXT for treatment of a bacterial infection. Patients were excluded if serum creatinine data prior to and after initiation of SXT were unavailable, they had AKI or were on hemodialysis prior to SXT initiation, or they were admitted to an oncology unit.

RESULTS

Of 98 patients who met inclusion criteria, 24 (24.5%) experienced stage I AKI and 16 (16.3%) experienced stage II or III AKI. The mean treatment duration with SXT at time of AKI development was 5.9 days. Coadministration of SXT with other nephrotoxic medications increased the risk of development of AKI (OR, 1.7; 95% CI, 1.2–2.4). Hyperkalemia was noted in 29 patients (29.6%), anemia in 39 patients (39.8%), thrombocytopenia in 30 (30.6%), and neutropenia in 39 (39.8%).

CONCLUSIONS

Changes in renal function suggestive of AKI occur frequently in pediatric patients receiving at least 5 days of treatment with SXT, particularly when using serum creatinine as a marker of AKI. In contrast, when using urine output rather than serum creatinine, the incidence is much lower and may be more reflective of a true change in renal function. Coadministration of nephrotoxic agents increases the risk of development of AKI. Anemia and hyperkalemia are common in patients receiving SXT and not associated with development of AKI. Further prospective study is warranted to validate these results.
Use of Calcitonin for Hypercalcemia in a Premature Neonate With Congenital Mesoblastic Nephroma
Authors: Kleespies Malia S. , Shah Pooja A. , Bondi Deborah S.
Published: September 2022

We report on a premature neonate (31 4/7 weeks' gestation) who presented with hypercalcemia secondary to congenital mesoblastic nephroma (CMN), the most common type of renal tumor in neonates. Typical presentation includes a palpable abdominal mass or swelling and may include abdominal pain, hematuria, fever, or hypertension. A less common complication of CMN is hypercalcemia of malignancy. Although the primary management strategy for hypercalcemia of malignancy is to treat the underlying disease, there are several agents that can be used as well for acute hypercalcemia including fluids, loop diuretics, corticosteroids, bisphosphonates, and calcitonin. However, there is minimal evidence to guide efficacious and safe treatment selection and dosing as hypercalcemia is a rare complication of this tumor type. This case adds to the current body of literature as only the second case of parathyroid hormone-related peptide-mediated hypercalcemia in a preterm neonate treated with calcitonin and is the first to specify a successful dose escalation strategy of calcitonin for this indication.

Series 60 CB= 0.6 represents an important class of ships for which vast amount of experimental data is available. Thus, it represents an ideal test bed for validating Computational Fluid Dynamics (CFO) codes. The code UNCLE incorporates the recently introduced algorithm for tracking incorporates the recently introduced algorithm for tracking unsteady free surface flows in a time accurate manner. In this algorithm, to facilitate the tracking of the free surface, a background grid is employed. Using the background grid the free surface grid points are forced to move along predetermined paths in order to simplify the grid regeneration process at the new time level. Newton's method is used to find the intersection of the background grid lines with the free surface. This allows to preserve the shape of the free surface during various grid operations at a given time level. The governing equations of the flow field are cast with respect to an unsteady Eulerian coordinate system and solved using the modified artificial compressibility method. The resulting numerical algorithm is implicit and time accurate and is formulated based on a finite volume approach. Roe's formulation is used for obtaining the first order inviscid numerical fluxes and van Leer's MUSCL approach is used for obtaining higher order (third) corrections. Central differencing is used for the viscous terms and a two point backward Euler formula is used for the time derivative. The same algorithm is also used for implicitly solving the free surface kinematic condition which is cast with respect to surface curvilinear coordinates. The numerical results are compared with the experimental results. The flow conditions are Fr= 0.316 and Re= 4,020,000. The results are quite encouraging.

Modelling the Effect of Lateral Ice Pressure on Icebreaking Resistance
Authors: Spencer Donald , Hardiman Ken
Published: September 2022

The effect of lateral ice pressure on the level ice resistance of a 1/30 scale model of an OBO is examined experimentally. The model was equipped with an instrumented side panel. The apparatus for producing lateral pressure is described, as well as the model tests themselves. Rubble thickness and applied pressure were varied during the experiments. A model is developed to describe the observed change in resistance. The model assumes that the resistance increase is due to ice-hull friction resulting from the ice pressure. The results from the instrumented panel suggest that approximately 2/3 of the applied pressure is seen at the hull. The study also found that the pressure only acts on the bow region and parallel middle body.
Precision Weld Repair of Worn Joints In A Towing Basin Track
Authors: Siewert T. A. , Bradel J.
Published: September 2022

This report describes the development and implementation of a procedure to repair the surface of the support track for a hydrodynamic test carriage at the Naval Surface Warfare Center's, Bethesda, Maryland ship-model towing basin. About 50 years of use had caused localized wear at the track joints, wear that was limiting the precision of hydrodynamic tests. Because of its special shape and precise installation, replacing the original track was not economically feasible.

A welding electrode was found that could match the original properties of the track surface, and a repair procedure was developed that rebuilt the track ends to their original geometry and properties. After the repair, accelerometer measure­ments on the carriage showed that the repair reduced the vibration due to the wear by over 75 percent, an improvement that returned the track to well within an acceptable range for the hydrodynamic tests.

Authors: Waters Jennifer K. , Kriebel David L. , Johnson Jeffrey , Chakrabarti Subrata , Berek Eugene
Published: September 2022

Laboratory tests were conducted to simulate the wave loading on a Gulf of Mexico production caisson under extreme hurricane conditions with intermediate depth breaking waves superimposed upon simulated hurricane-generated currents. This work was motivated by the continuing uncertainties in the way that both wave current loading and breaking-wave loading are predicted. The 20th edition of the American Petroleum Institute Recommended Practice 2A (API RP2A) provides, for the first time, a recommended procedure for computing wave-current loading. The API does not recommend a method of accounting for wave breaking, and it has not been known how well the API procedure works for typical shallow water hurricane conditions when breaking waves are superimposed on currents.
A Probabilistic View of Wave Interaction with Spar Platforms
Authors: Niedzwecki J. M. , Rijken O. R.
Published: September 2022

The need to look at alternative platform concepts for the development of deep water prospects has lead to the Spar platform concept. The large Spar platform design used in the experimental study discussed in this article was a deep draft cylindrical hulled platform which had a central moonpool. It was designed to be secured to the seafloor using a spread mooring system. The Spar platform motions and wave runup on the Spar were measured and are characterized herein using cumulative probability plots and statistical moments. The plots show the nature and degree of non-Gaussianity. These plots together with the statistical moments provide in­sight into the degree of nonlinearity of the motions and wave platform interactions observed.

Authors: Bose Neil , Luznik Luksa
Published: September 2022

Uncertainty analysis was used in a propeller open water test to reduce levels of experimental uncertainty. Sources of error which had the most influence on the total uncertainty in the measurements were identified. The overall level of uncertainty in the measurements during these tests was assessed. These results were used to reduce uncertainty levels in a repeat test. The analysis for both tests is presented. The aim was to use the results to reduce future uncertainty levels in doing this type of test.
Some Observations on Various Testing Techniques for Calm Water Planing Boat Resistance
Authors: Shaughnessy James J. , Zseleczky John J.
Published: September 2022

During the Winter of 1994 and Spring of 1995, a series of experiments for determining the effects of various parameters on the calm water resistance of a planing boat were conducted at the United States Naval Academy Hydromechanics Laboratory. For all of the tests discussed in this paper the model was ballasted to the same loading condition and towed with the same equipment. The differences that were investigated involved details of model testing that are usually left to the discretion of the institution performing the tests. Some of the differences were found to have profound effects on the resistance and trim that were measured. This paper will describe the test facilities, the model and parameters that were varied, and make some general conclusions and observations regarding the effects of each of the test parameters. The results will also be compared with accepted numerical prediction methods. (The particular method used for this paper is from "Hydrodynamic Design of Planing Hulls" by Daniel Savitsky [1] with modifications by Jacques Hadler [2] .)
Validation of Coupled Inviscid/Viscous Flow Analysis for the Ducted Propulsion of an Axisymmetric Body
Authors: Nguyen Phuc N.
Published: September 2022

A technique, which couples the lifting surface theory and Reynolds-averaged-Navier-Stokes (RANS) method to analyze the propulsor-hull interaction, was evaluated with towing tank measurements. The experimental database was for an axisymmetric body with a ducted propulsor. This database consisted of propeller thrust coefficient, torque coefficient, and duct force at different advance coefficients. The thrust and torque coefficients were predicted within 10% near design condition. The calculated duct thrust and the thrust deduction coefficients were higher than the measured values all across the operating range. Accounting for the viscous effect on the lifting surfaces is suggested for further study. Evaluation with other databases is strongly recommended.
Pitch and Heave and Heave Motion Identification Using Neural Network Techniques
Authors: Hadd M. R.
Published: September 2022

This paper outlines a procedure that can be used to identify the parameters in the coupled heave-pitch equations using the measured heave and pitch responses of a ship in a random sea. Equations for the mean values of heave and pitch motions are obtained using the concept of random decrement. In this paper we show how measured records of heave and pitch motions in random seas can be used to identify the parameters in the mean values equations of these motions. The technique described in the paper uses neural networks to identify these parameters. Preliminary results show that this approach is promising. Studies for the refinement and validation of the approach are currently underway at Memorial University.
U. S. Coast Guard Modular Model Maneuvering Tests
Authors: Sedat Robert , Fuller Nathan
Published: September 2022

In order to develop a rational model for ship maneuvering, a series of model tests was conducted to isolate forces on the hull, propeller and rudder, and to study the interactions between them. Rotating arm and linear towing tests were conducted on a large Mariner model, and a systematic series of smaller models. The large model Mariner tests were conducted by David Taylor Research Center (DTRC) at one speed, and at various drift angles and yaw rates. In order to study hydrodynamic forces on each component and their interactions, the same tests were repeated for the bare hull, the hull with rudder, and for the hull with rudder and operating propeller. Two types of rudders were used for these tests. One was an airfoil-shaped rudder whose stock passed through the hull without contact. This was fitted with four multi-hole pitot tubes to measure inflow velocity and direction at different spanwise locations on the rudder's leading edge. The other rudder, a flat plate "flag".

Authors: Seo Dongok , Yoon Byul Hee , Byun Joonho , Park Wonhyoung , Park Jung Cheol , Ahn Jae Sung
Published: September 2022

Moyamoya disease (MMD) is a rare progressive steno-occlusive cerebrovascular disorder. Currently, revascularization surgery is used as optimal treatment to overcome MMD. However, revascularization for MMD has reported several complications. Also, iatrogenic complications such as pseudoaneurysms formation or dural arteriovenous fistulas (dAVFs) formation—has been identified in rare cases after the surgical intervention for revascularizations.
We describe two cases. In first case, the patency of the anastomosis site was good and saccular type pseudoaneurysm formation was found at parietal branch of posterior middle meningeal artery (MMA) in transfemoral cerebral angiography (TFCA) performed on the twelfth day after surgery. We decided to treat pseudoaneurysm by endovascular embolization the next day, but the patient was shown unconsciousness and anisocoria during sleep at that day. Computed tomography showed massive subdural hemorrhage at the ipsilateral side, thus we performed decompressive craniectomy and hematoma evacuation.
In second case, the patency of the anastomosis site was good and dAVF formation at right MMA was found in TFCA performed on the sixth day after surgery. We performed endovascular obliteration of the arteriovenous fistula under local anesthesia.
Pseudoaneurysm formation or dAVF formation after revascularization surgery is an exceptional case. If patients have such complications, practioner should carefully screen the patients by implementing digital subtraction angiogram to identify anatomic features; as well as consider immediate treatment in any way, including embolization or other surgery

Sebald, o autor busca refletir sobre as estratégias de visualidade inseridas nos textos (como o olhar é uma categoria historicamente construída), bem como realizar uma discussão crítica acerca da inserção de imagens dentro dos romances (a questão da materialidade, da montagem dos fragmentos visuais e do estatuto ético da representação visual). Cada capítulo do livro é intitulado a partir de uma obra comentada por Sebald em seu trabalho. Tais obras podem ser tanto livros (de ficção ou de teoria) quanto pinturas, como é o caso, por exemplo, de Lição de anatomia, de Rembrandt, ou Sob o signo de Saturno, que remete a um livro de ensaios de Susan Sontag. Com isso, cada capítulo propõe uma discussão teórica no âmbito da crítica literária e da literatura comparada, lidando com a poética de W. G. Sebald e, ao mesmo tempo, remetendo a outros textos e imagens em viés comparatista.
MF-Storm: a maximum flow-based job scheduler for stream processing engines on computational clusters to increase throughput
Authors: Muhammad Asif , Abdul Qadir Muhammad
Published: September 2022

Background

A scheduling algorithm tries to schedule multiple computational tasks on a cluster of multiple computing nodes to maximize throughput with optimal utilization of computational and communicational resources. A Stream Processing Engine (SPE) is deployed to run streaming applications (computational tasks) on a computational cluster which helps execution and coordination of these applications. It is observed that there is a gap in the optimal mapping of a computational and communicational load of a streaming application on the underlying computational and communication power of the resources (cluster). Frequently communicated tasks are scheduled at different processing nodes with relatively slow communicating links. This increases network latency with a decrease in resource utilization. Hence, reduces the achieved throughput of the cluster significantly.

Methods

MF-Storm, a max-flow min-cut based job scheduler is presented to achieve a near-optimum schedule to maximize throughput. It schedules a streaming application by considering the processing, communication demands, available computational and communicational resources in a heterogeneous cluster, dynamically with minimized scheduling cost. To keep the scheduling cost minimum, the scheduler is built in a pipeline with two major stages: in the first stage, the application’s tasks graph is partitioned using the max-flow min-cut algorithm to minimize inter-partition traffic, and in the second stage, these partitions are assigned to computing nodes according to the computational power of the cluster’s nodes.

Results

Extensive experiments were done to evaluate the performance of MF-Storm using different topologies with multiple scenarios on a physical cluster implementation. Results showed on average 148% improvement in throughput with 30% less computational resources as compared to different state-of-the-art schedulers.
Avoidance of copper by fathead minnows (Pimephales promelas) requires an intact olfactory system
Authors: Fatima Rubab , Briggs Robert , Dew William A.
Published: September 2022

Fish can detect and respond to a wide variety of cations in their environment, including copper. Most often fish will avoid copper during behavioural trials; however, fish may also show no response or an attraction response, depending on the concentration(s) used. While it may seem intuitive that the response to copper requires olfaction, there is little direct evidence to support this, and what evidence there is remains incomplete. In order to test if olfaction is required for avoidance of copper by fathead minnows (Pimephales promelas) copper-induced movement was compared between fish with an intact olfactory system and fish with induced anosmia. Fish in a control group or a mock-anosmic group avoided copper (approximately 10 µg/L or 62.7 nM copper sulphate) while anosmic fish did not. The evidence demonstrates that an intact olfactory system is required for copper sensing in fish.

Authors: Ignesius Nikita Christy
Published: September 2022

Two decades passed by but the 1998 riot case is still remembered as a traumatic event for Chinese Indonesian people. Started from the economy crisis in July 1997 where Rupiah currency dropped and gave a huge damage to the Indonesia economy and politic section. This crisis made the poor non Chinese Indonesian envied the Chinese Indonesians. The riot reached its peak in May 1998 where Chinese Indonesians got harassed. Many Chinese Indonesians decided to leave Indonesia to live in other countries temporary or forever. Each generation keep reminding this incident made the young Chinese Indonesian generation aware of the Non Chinese Indonesian. This research aims to reveal the thoughts of Chinese Indonesian about the Indonesian government in handling the 1998 riot and examine the reason behind the Chinese Indonesian thoughts. The researcher also hoped that this research can be used as reference in other research related to this 1998 riot.Keywords : 1998 riot, Chinese Indonesians, Indonesia’s Government
Using Offerings to Attract More Customers and Maximize the Sales of Victory Store
Authors: Pratami Theresia Surya
Published: September 2022

Victory Fotokopi/ATK store is a store that provides both services such as photocopy, print, laminating, scan and book binding (Jilid) and products such as stationary, office equipment and birthday supplies. The main problem of Victory store is it does not have any uniqueness or value that makes it different from other stores. Therefore, offerings such as volume discount and bundling are used in this project. A digital poster also used to distribute the offerings through WhatsApp Business to the customers. In conducting the project, I used the theories of four main subjects: brand awareness, marketing, promotion and unique selling point. Also, nine sub subjects: brand advertising, logo, blue, red and yellow colors, digital poster, banner, social media marketing, WhatsApp, offering in marketing, volume discount and bundling. Basically, as the main purpose is to maximize the sales, offerings will be the best solution where it could attract the customers to come and shop more often to the Victory store. Keywords: Brand and Brand Awareness, Brand Advertising, Marketing, Social Media Marketing, Offering in Marketing, Volume Discount, Bundling, Digital poster and Unique Selling Point
A Comparison Between Disney Earlier and Recent Princess of The Third Generation of Disney Animated Films as Seen in Rapunzel in Tangled and Moana in Moana
Authors: Anindita Nastasha Primera
Published: September 2022

This study compares the girl power characteristics such as bravery, independence, and intelligence in identifying Rapunzel as the earlier princess character and Moana as the recent princess character of the third generation of Disney Princesses in the two Disney Princess Animated Films titled Tangled and Moana. As a result of this study, I found that in terms of bravery, Moana as the recent princess, is more daring to make decisions and take risks when compared to Rapunzel as the earlier princess of the third generation. In terms of independence, it can also be seen that Rapunzel still seems to rely more on other people to help her find a way and protect herself, in contrast to Moana, who can find the destination by herself and work together with other people and make them become her partners. In terms of intelligence, both Rapunzel and Moana are good at managing their daily activities, but in terms of solving problems, Rapunzel still uses the power of magical stuff, unlike Moana, who uses all her mind and strength to solve the problems she faces.Keywords: girl power, bravery, independence, intelligence, characteristics

Published: September 2022

In this study, I want to analyze two films called Moana and Brave by Disney Animation. In this film there is a difference in characteristics of a princess who is usually in the field of others, just quiet and waiting for others to help them. That is the reason why I wanted to focus on the main characters named Moana and Merida who have the other side of a princess usually. This thesis talks about the issue of how the characters of Moana and Merida reflect the characteristics of girl power. The thesis aims to show that Moana and Merida can reflect the characteristics of Girl power through their decisiveness, smartness and boldness. In this study, I used girl power theory that Rebecca Walker as pioneer of the third-wave pioneer. As a result, I have found that Moana and Merida reflected the characteristics of Girl power that made them show a new side of the characteristics of a princess that is usually displayed by Disney.Keywords: Disney, Girl Power, decisiveness, smartness, boldness
