Published: April 2022

This study aims to examine how significantly Flexible Work Arrangements (FWA) contribute to the improvement of civil service inter-organizational networks by looking at various factors, including trust, adaptability, information technology readiness, and other control variables. This study uses a mixed-methods design. The quantitative approach uses an online survey of 675 civil servants’ respondents from central and regional agencies. A qualitative approach with in-depth interviews and focus group discussions with local civil service in West Java Province, Central Java Province, and Semarang City. The collected data is then analyzed Path Analysis using SPSS version 25. The research revealed that Flexible Work Arrangements contributed to increasing the influence of the level of trust on the work network. Meanwhile, FWA do not contribute to the effect of adaptability and readiness of information technology on the work network. This is supported by qualitative data which shows that Trust is the main factor to increase the network when implementing FWA in order to create a good network, with high and solid trust, both trust in leaders, colleagues, and stakeholders, then any instruction as soon as possible is realized into a good cooperation network when FWA is realized by developing a Flexible Work Arrangement system

Authors: Prakoso Cathas Teguh
Published: April 2022

Recent developments show scholars argue that when electronic government systems reach certain stages, they will develop into Digital Government. However, studies on Digital Government evaluation, especially in the Indonesian context, are still few. With that in mind, this article aims to describe the maturity of the digital government system in the Population and Civil Registry Office (Disdukcapil) of the Kutai Kartanegara Regency. It is based on the assumption that Disdukcapil has successfully implemented electronic government, as proven by their multiple recognitions and can be considered at the digital government stage. Field observation and in-depth interviews with key informants are employed to collect the relevant data. All the data are then analyzed qualitatively, and then it uses digital government evolution variables developed by Janowski (2015) to determine the stage of Disdukcapil digital government. The result shows that within a four-stage maturity level, the digital government of Disdukcapil of Kutai Kartanegara Regency has reached the third stage, based on the fulfilment of each stage's variables. It is hoped that this study can contribute to Digital Government studies in Indonesia

Published: April 2022

Post-armed conflict and tsunami disasters, the Government of Aceh seek to implement public services and development programs transparent and accountable. One of the strategic steps taken is its implementation based on the mandate of the public information disclosure Act (KIP Law) and Aceh Qanun (Aceh Regional Regulation) Number 7 of 2019 on KIP Management. Even though it already has KIP rules, there are still some problems in its implementation, such as compliance with SKPA in providing public information and the number of disputes over public information. This study aims to identify and analyze the dynamics of the implementation of public information within the Aceh Government and the challenges of public management. This study uses a qualitative method through observation, document review, and interviews. The basis of data analysis uses Information Commission Regulation Number 1 of 2010 and Aceh Governor Regulation Number 57 of 2018. The results are (1) SKPA has work plans, programs, and activities for the management of public information; (2) there is a budget allocation for Information and Documentation Implementation Officers (PPID); (3) It has a list of public information and SOPs. The findings of this study also find logistical consequences for the future of Aceh's development through the KIP perspective. Information that is open, accessible, and inexpensive can nurture public trust in the Aceh Government and in itself will increase community participation in development. Trust is the principal social capital in the development of community welfare

Authors: Eryani Yulia , Azizi Khiratul , Ningsih Listia
Published: April 2022

The Functional Training for Pharmacy and Food Junior Expert Supervisors has been conducted since 2019 with classical face-to-face method (offline). In early 2020, the method was replaced with blended learning methods using asynchronous and synchronous modes. The Covid-19 Pandemic requires the synchronous approach, initially conducted offline face-to-face with the participants, to replace online meetings using a video meeting application. This study aims to analyze the effectiveness of the functional training for pharmacy and food junior expert supervisors with the blended learning method. This research performed a quantitative parametric method using the Mann-Whitney test method. The number of offline training respondents was 59 people, and online training (blended learning) respondents were 753 people. The variable used to measure the effectiveness was the training evaluation. The study results indicated that the online activity of the Pharmacy and Food Junior Expert Supervisors was more effective than the offline training. This result was proved by The Mann-Whitney test method using SPSS. The evaluation result before the Covid-19 Pandemic with the classical method was significantly different from Blended learning during the Covid -19 pandemic, which was more effective. In this study, researchers also employed SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis to explore essential aspects for continuing this training. Thus, the blended learning method is effective and continues using an online video meeting application

The research material consisted of 802 relevés recorded during 2002–2004 using the Braun-Blanquet method in plant communities of meadows and pastures and in the neighboring marshes, xerothermal swards, as well as water and synanthropic plant communities. The floristic diversity was assessed at the species and plant-community levels. Attention was paid to the share of species of grasses, papilionaceous and honey plants, medicinal herbs and protected and rare plants, as well as those threatened by extinction, in the flora of the studied area. In plant communities, in which minimum 5 relevés were recorded, each time on/from the area of 100 m2, the total number of species was counted, the average number in the relevé and the Shannon-Wiener’s diversity index were calculated. A general, natural-scientific valorization of the San river valley was carried out on the basis of floral species composition and numerical data of analyzed plant communities on sample areas. Additionally, attention was paid to differences in bio-diversity of syntaxa identified within the Arrhenatheretum elatioris and Lolio-Cynosuretum associations. These associations occupied the largest area among the meadows. Phytosociological studies led to identifying 80 phytocoenoses at the association and community ranks, which were classified to 11 classes. Phytocoenoses of the Molinio-Arrhenatheretea and Phragmitetea classes dominated. The flora of the described non-forest communities consisted of 591 species of vascular plants, including over 30% of rare taxa, protected and/or threatened by extinction on the regional and national scale. Particularly valuable are the plant communities in marshes and xerothermal swards, which are threatened by extinction because of changes in habitat conditions and changes in the manner and intensity of utilization, among others. Only 35% of the identified phytocoenoses are not under threat. Species particularly threatened in that area comprise: Trapetum natantis, Caricetum paniculatae, plant community with Fritillaria meleagris, among others, which occurred on single stands only. Floral species composition and the richness of plant communities on meadows, rushes and others of nonforest areas have confirmed clearly that the San river valley is of high value for natural science. The value of the Shannon-Wiener index was diversified (H = 1.29-3.54) and usually lower for plant communities of Phragmitetea class in water and rushes, and higher for phytocoenoses of the Molinio-Arrhenatheretea class.

The determination of different light conditions and renovation methods on the improvement of grass areas was the aim of the study. Two grass areas of different light conditions were set up in the Palace-Park area and the renovation activities (cutting, fertilising, oversowing and full cultivation) were carried out. The changes of turf level, botanical content and general turf condition were analysed. Five times a year-cutting affected the decreasing of ruderal and shrubby plants share in the turf, especially in light sun conditions, but the development of low grasses was not fully satisfactory. The fertilising did not affect the turf improvement in spite of extensive Dactylis glomerata development. In the light sun conditions the oversowing, and especially full cultivation, secured quick turf and botanical composition improvement.

Published: April 2022

The objective of this cross-sectional study was to evaluate the hydration status of Czech First League soccer players, and to compare the reported fluid intake, perceived fluid intake and thirst sensation of euhydrated (EU) and dehydrated (DE) players. The study involved 124 Czech male professional soccer players (age 25.2±5.0 years) participating in annual winter, pre-season laboratory testing. Hydration status was assessed based on urine specific gravity (USG), euhydration was set at USG≤1.020. Fluid intake and thirst perception were evaluated by a questionnaire. The sample mean for USG was 1.021±0.008, 56% of players were dehydrated. Reported daily fluid intake was significantly (p<0.001, d=0.95, large effect) higher in EU compared to DE players. Daily fluid intake negatively correlated with USG (rS=-0.46, p<0.001, medium effect). The fluid intake perception score was significantly (p=0.005, d=0.54, medium effect) better in EU compared to DE players. Reported intake perception scores negatively correlated with USG (rS=-0.32, p<0.001, medium effect). However, there was no correlation (rS=-0.09, p=0.34, trivial effect) between thirst perception scores and USG. Thirst perception scores were not significantly different between EU and DE players (p=0.35, d=0.18, trivial effect). Our results indicated that self-assessment of both daily fluid intake and perceived fluid intake matched with objective hydration status, while self-assessment of thirst perception was not an appropriate indicator of hydration status in elite soccer players.
The Creation of Goal-Scoring Opportunities at the 2019 FIFA Women’s World Cup
Authors: Kubayi Alliance
Published: April 2022

The aim of this study was to analyse how goal-scoring opportunities (GSOs) were created at the 2019 FIFA Women’s World Cup. The sample consisted of 868 GSOs that led to a shot at the goal throughout all 52 games during the tournament. All games were downloaded from the InStat platform. Descriptive statistics, chi-square of association and binary logistic regression analysis were used to analyse the data. Of the 868 GSOs, 81 (9.1%) resulted in goals. A significant association was observed between GSOs and the type of attack (χ2=6.38, p=0.01, V=0.09), with more goals being scored from a counter-attack (12.7%) than an organised attack (7.5%). Counter-attacks recorded a higher odds ratio in univariate analysis (OR=0.56; 95%CI:0.35–0.88; p=0.01) than in multivariate analysis (OR=0.46; 95%CI:0.28–0.76; p=0.002). The multivariate analysis further indicated a significant probability of scoring when ball possession started in the middle third of the field (OR=0.19; 95%CI:0.44–0.88; p= 0.01). The current study has practical implications for soccer coaches to develop and implement training sessions to improve goal-scoring chances of women’s teams at international competitions.

This study examined the accuracy of predicting a free-weight back squat and a bench press one-repetition maximum (1RM) using both 2- and 4-point submaximal average concentric velocity (ACV) methods. Seventeen resistance trained men performed a warm-up and a 1RM test on the squat and bench press with ACV assessed on all repetitions. The ACVs during the warm-up closest to 1.0 and 0.5m.s-1 were used in the 2-point linear regression forecast of the 1RM and the ACVs established at loads closest to 20, 50, 70, and 80% of the 1RM were used in the 4-point 1RM prediction. Repeated measures ANOVA and Bland-Altman and Mountain plots were used to analyze agreement between predicted and actual 1RMs. ANOVA indicated significant differences between the predicted and the actual 1RM for both the 2- and 4-point equations in both exercises (p<0.001). The 2-point squat prediction overestimated the 1RM by 29.12±0.07kg and the 4-point squat prediction overestimated the 1RM by 38.53±5.01kg. The bench press 1RM was overestimated by 9.32±4.68kg with the 2-point method and by 7.15±6.66kg using the 4-point method. Bland-Altman and Mountain plots confirmed the ANOVA findings as data were not tightly conformed to the respective zero difference lines and Bland-Altman plots showed wide limits of agreement. These data demonstrate that both 2- and 4-point velocity methods predicted the bench press 1RM more accurately than the squat 1RM. However, a lack of agreement between the predicted and the actual 1RM was observed for both exercises when volitional velocity was used.

Published: April 2022

For an athlete to be successful at the professional level, he or she should be characterized by extraordinary preparation in four areas: physical, technical, cognitive (related to game strategy, perception, and decision-making), and emotional (coping, emotional control). This study aimed to determine the level of selected cognitive traits in handball players while considering their sports level and assigned position on the court. Fifty handball players participated in the study. Participants consisted of 35 national team players, six first-division players, and nine second-division players. There were no significant differences between players from the elite (national team) and the sub-elite (I and II divisions) group. The results identified major differences in selective attention and short-term memory between handball players assigned to different positions (goalkeepers, compared to players in other positions, had lower attention and short-term memory). Thus, it is possible to develop a more effective psychological training program. However, it must be remembered that the results showed great variability among handball players. With this in mind, individual differences should be taken into account when planning psychological interventions.

Authors: Gonçalves Jacinto Karla , Varga Szabolcs , Silva Carlos
Published: April 2022

Being 20% of the building's total energy consumption, air conditioning can be a key to reduce significantly the energy demand and environmental impact. The blame lies in the compressor. The ejector is a simple equipment with zero energy consumption, ideal to assist the mechanical compressor. However, the ejector flow domain is complex and difficult to compute, once that is highly turbulent. The ordinary turbulence models are based on Reynolds Averaged Navier-Stokes, however, they cannot accurately compute the turbulence behavior inside the ejector. The optimal way to reproduce the interior flow is DNS, nonetheless, the computational cost is the major problem. This paper proposes two possible solutions to make DNS possible nowadays.

Published: April 2022

Reinforcement of a structure is necessary in unpredictable changes or also for rehabilitation, due to exposure to weather conditions, causing considerable damage that can lead to the collapse of the structure. The present study aims to evaluate the behavior of the strengthening with sheets of glass fiber reinforced polymer (GFRP) with thicknesses of 3 mm, bonded with structural epoxy-based adhesive applied in the shear area of reinforced concrete beams, spaced in three different configurations and bonded on the two faces of the beam. The beams were cracked previously to simulate a damaged structure and strengthened later to obtain the maximum load of rupture after the application of the strengthening. With the obtained results it can be verified an increase of ductility in the reinforced concrete beams. The increase of the load capacity was obtained in the beams with strengthening with smaller spacing between the sheets.

Published: April 2022

Increased demands for safety and environment concerns have led to a greater use of advanced high strength in the automobile industry. The consequent challenges to sheet metal forming processes include higher contact pressures between dies and blanks with resulting consequences in increased wear and failures. In this article a numerical model is applied to analyze contact pressure along the tool die radius, where wear is particularly severe. Several sheet metal materials are numerically investigated, in order to quantify the pressure distribution along the radii which in turn has important effects on tool wear. The results show that different materials, its strength and behavior affect not only the contact pressure, but also the contact distribution at different zones of analysis.
Casting A356+SiCp with ultrasonically treated melts
Authors: Carneiro Vitor , Grilo José , Puga Hélder , Duarte Isabel , Jesus C.
Published: April 2022

Low mass fractions (0.05 wt%) of SiC micro sized particles have been added to an A356 melt and dispersed by ultrasonic vibration to study their impact on the microstructural morphology of cast samples. It is shown that the ultrasonic melt treatment at 680°C can promote a homogenized distribution of the reinforcement while also degassing the melt and induces a moderate grain refinement. Even though SiC may act as a nucleant, its use did not induce a significant grain refinement relatively to ultrasonically treated unreinforced melts. Adding SiC microparticles, however, seems to enhance Eutectic Si modification, although it contributes to its slight coarsening at the expense of Mg2Si.
Development prospects for the Russian market of equipment and services to microgeneration under sanctions
Authors: RATNER Svetlana V. , LAZANYUK Inna V.
Published: April 2022

Subject. Due to the pressure of increased sanctions on Russia’s economy, the development of renewable energy depends heavily on internal and external solvent demand for photovoltaic panels and wind turbines. A significant share of demand can be provided by the development of microgeneration based on renewable energy sources in the residential and commercial sector.
Objectives. The aim is to perform a comprehensive analysis of real and potential barriers to the development of the microgenerating equipment market on the basis of renewable energy sources, both on the demand side and on the supply side.
Methods. We conducted the supply-side research by studying the official websites of Russian companies offering solutions for autonomous and backup power supply. Then we interviewed representatives of companies, using the "mystery shopper" method. The demand-side research was undertaken through telephone interviews with professionals and stakeholders related to the microgeneration market development.
Results. We found that nowadays the main barriers to market development are high capital costs and a long payback period for microgeneration projects, as well as insufficient level of development of services for design and installation of microgenerating equipment.
Conclusions. The proposed range of equipment for microgeneration is quite wide and is unlikely to be reduced due to new sanctions imposed by Western countries. The equipment is made either in Russia or in China. However, the quality of information about products and services provided by producer companies is insufficient to successfully promote microgeneration.

Published: April 2022

Research subject. The article presents the results of a comprehensive study of a column of organomineral deposits (750 cm) in the tract of Lake Peschanoe (Amur Region, between the Amur and Zeya rivers).

Material and methods. In the studied section, the composition of organomineral deposits were examined based on radiocarbon dating and palynological analysis.

Results. According to radiocarbon dating, the sedimentation began over 4 thousand calendar years. Specific features of the accumulation and distribution of rock-forming oxides and microelements along the organomineral sedimentary profile were established. The mineral composition is dominated by quartz, feldspars, amphiboles, pyrite, garnet and biotite. The highest values of the scattering coefficient in the thickness of the deposits are typical of Hg (8.0), Tl (6.7), La (5.3), below – Zr, Rb and Li (4.7, 4.4 and 4.1, respectively).

Conclusions. The study of the geochemical characteristics of organomineral deposits allowed us to identify the industrial period of sedimentation, which was characterized by an increase in the concentrations of Hg, Cd, Pb and Sn. The background contents of elements in the organomineral deposits of the Lake Peschanoe tract can be used as a regional background for deposits in the transboundary territory of the Upper and Middle Amur and its tributaries. The calculated geochemical coefficients indicate the freshwater content of the basin and the alternation of stagnant and oxidizing environments during sedimentation. The increased Ca/Sr values are associated with a change in the climatic regime towards cooling, which occurred during the last 4 thousand years in this area: 4300–4100, 2400–2100, 500–230 years ago.

Electrocatalytic Radical-Polar Crossover Hydroetherification of Alkenes with Phenols
Authors: Park Steve , Jang Jieun , Shin Kwangmin , Kim Hyunwoo
Published: April 2022

We disclose a general electrocatalytic hydroetherfication for modular synthesis of alkyl aryl ethers by utilizing a wide range of alkenes and phenols. The integration of the two involves an electrochemically instigated cobalt-hydride catalyzed radical–polar crossover of alkenes that enables the generation of key cationic intermediates, which could readily be entrapped by challenging nucleophilic phenols. We highlight the importance of precise control of the reaction potential by electrochemistry to obtain optimal chemoselectivity. Notably, this reaction system is pertinent to late-stage functionalization of pharmacophores that contain alkyl aryl ethers which has constantly been challenged since traditionally unconventional methods.
Investigation of the dissipative properties of Au-Ag nanostructures through Electron Energy Loss Spectroscopy

Published: April 2022

We describe the unusual dielectric properties of Au-Ag nanostructures at a single particle level using electron energy loss spectroscopy. It has been shown previously that these nanostructures deviate from their usual metallic characteristics of metallic Ag and Au. In particular certain variants of these materials appear to undergo a transition to an immeasurably low resistive state as well as a strong diamagnetic state that is not usually associated with Au and Ag themselves. More significantly these nanostructures exhibit absence of Mie like resonances associated with Au and Ag. Instead, these exhibit negligible optical absorption in the UV-VIS-NIR range. Here this unconventional electromagnetic response was probed at a single particle level. We find that the absence of dissipation is also reflected in the electron loss spectra. The lack of distinct electron energy loss features in particles with a known composition enables us to unambiguously assign these observations to actual particle properties. We tentatively interpret our observations as arising due to a reduction of free electron density in Au and Ag nanostructures. Further it was also shown that the conventional plasmonic modes can be recovered by altering material composition.
Témoins de témoins : le témoignage indirect dans Vie de ma voisine de Geneviève Brisac
Authors: Faltoni Enrico Maria
Published: April 2022

Vie de ma voisine (2017) is the true the story of Shoah survivor Eugénie Plocki told through the eyes of her neighbour and in the words of Geneviève Brisac. A life story, it is also a testimonial and a biography. This article examines narrative and linguistic choices that allow Brisac to demonstrate both the limits of her testimonial and her duty to stand witness. It also shows how the biographical pact she has committed to coincides with the birth of a friendship.
An alternative approach to adjust the iron status for inflammation in population: an exploratory study
Authors: Rahman Sabuktagin , Shaheen Nazma
Published: April 2022

Background: Iron deficiency (ID), one of the major micronutrient deficiencies globally, is challenging to measure. This is due to the dual character of ferritin which measures both the ID and concurrently affected by inflammation and infection. To address this, inflammation biomarkers—e.g., CRP (C-Reactive Protein) and AGP (Alpha-1- Acetylated Glycoprotein) are used through various standard methods to report inflammation-adjusted ID. However, there are problems with these methods and their underlying principles. An exploratory study was conducted to suggest an alternative way for inflammation adjustment with the focus on changing the inflammation-cut off point of the biomarker.

Methods: Data of the Bangladesh National Micronutrient Survey 2011-12 were used in three population groups—preschool age children (6-59 month), school age children (6-14 years) and non-pregnant non-lactating women of reproductive age. Spearman Rank correlation was used between the iron status markers (ferritin, hemoglobin) vs. the inflammation biomarkers (CRP; AGP) at various cut-off levels of the inflammation markers, e.g., all-values, ≤ 5 mg/L, ≤1 mg/L, and ≤0.35 mg/L. ID was estimated over specified ranges of percentiles of the inflammation biomarker.

Results: Spearman Rank correlation between CRP and ferritin showed statistically significant coefficients at various cut-offs of CRP, except at CRP≤1 mg/L in preschool children and at CRP≤0.35 mg/L in school age children. The decrease in ferritin concentration was 6.7%-11.1% across the studied populations between the inflammation-unadjusted concentration and at CRP≤1 mg/L. Generally, the prevalence of ID was higher at CRP≤1 mg/L than at CRP> 1 mg/L. These findings suggested that a single inflammation biomarker, CRP with a cut-off of >1 mg/L excluded the corresponding cases of inflammation-elevated ferritin, allowing for a simpler estimation of the inflammation-adjusted ID in this setting.

Conclusion: Usage of CRP with the cut-off ≤1 mg/L is a useful, simplified and economic way to report the inflammation-adjusted ferritin-based ID in Bangladesh and similar settings with a modest infection burden. The method needs assessment in areas where the infection-burden is higher or in settings where malaria is endemic.
What Makes Ultra-Processed Food Appealing? A critical scan and conceptual model
Authors: Vignola Emilia F , Nazmi Aydin , Freudenberg Nicholas
Published: April 2022

There is growing evidence that consumption of ultra-processed food (UPF) has become a leading cause of global premature deaths and preventable diet-related diseases. To reduce consumption of UPF requires an understanding of the multiple forces behind it, including the understudied question of what makes UPF appealing. This critical scan of literature across multiple disciplines aims to fill this gap. We conclude that appeal is a multi-dimensional construct generated through the interplay of the products themselves, the people consuming them, and the practices of the corporations that manufacture, market, and distribute them. We argue that these relationships need to be unpacked to understand UPF appeal fully, and that public health interventions must take on the multiple dimensions of UPF appeal in an integrated way to effectively reduce its consumption. We propose a conceptual framework that can guide research to analyze the causes and consequences of UPF appeal and inform the development of policies and other interventions to reduce UPF appeal and consumption.

Published: April 2022

This article described the development of Ngebel tourism using a website. The tourism development concept uses the principles of e-government, such as government to citizens (G2C), government to government (G2G), and government to business (G2B). The study employed qualitative methods such as observation and focus group discussions (FGD) in collecting data. Data was analyzed using Nvivo 12 Plus software and the findings showed the Dolan Ngebel website applies the principles of government to citizens and government to business. This development was also received positively by the community and business people in the tourism industry. The website provides detailed information regarding the tourist attractions and facilities. Also, it is equipped with a map to make it easier for tourists to locate their destination. Overall, its use will help promote tourism to the locals and the international community. However, its development faces obstacles, including a lack of techsavvy human resources.
Demonstration of microbiological status of fresh fruits and determining the
efficiency of different decontaminating agents against the isolated bacteria

Consumption of fresh fruits increases along with the promotion of healthier lifestyles.
However, many foodborne illnesses have been reported due to the consumption of
contaminated fruits. Fresh produces are subjected to various treatments for minimizing
these outbreaks. The present study demonstrates the role of various simple household
methods including water washing and some other common chemical treatments for the
removal of bacterial load. By performing the spread plate technique, total heterotrophic
bacteria, Escherichia coli, Staphylococcus spp., Salmonella spp. and Listeria spp. were
determined in 60 samples of 6 categories including Apple (Malus domestica); Grape (Vitis
vinifera); Guava (Psidium guajava); Strawberry (Fragaria ananassa); Indian jujube
(Ziziphus mauritiana); Malabar plum (Syzygium cumini) before and after washing with tap
water, hot water, 100 mg/L sodium hypochlorite (NaOCl), 50 mg/L calcium lactate, 4%
acetic acid and 2 mL/L CleanAva for 20 mins at room temperature. All the tested
solutions were found to be effective and reduced bacterial loads in fruits compared to the
unwashed fruits samples (P<0.01). Treatment with NaOCl, calcium lactate, acetic acid and
CleanAva was the more effective washing technique rather than hot water wash. Two to
three log of the bacterial load was reduced when samples were subjected to treatment with
chemical decontaminating agents. The efficiency of washing depends on the purity of
water, and the types and concentration of the disinfectant solutions. An appropriate
washing technique needs to implicate to diminish bacterial load and the risk of foodborne
infections caused by fruits.

The Multidisciplinary Undergraduate Research Conference (MURC) is a conference for undergraduate students at the University of British Columbia (UBC) to showcase their research in front of their fellow UBC students, family, and friends. Researchers may choose one of three formats to showcase their research: oral presentation, poster, or virtual presentation. Presentations are categorized into four multidisciplinary themes: Health and Wellness; Individual, Community and Society; Sustainability and Conservation; and Innovation and Technology. Presentations were evaluated by UBC graduate students and faculty to provide students with feedback on their projects and presentation skills. MURC 2022 was the 19th iteration of the conference and the first ever hybrid (both in-person and virtual) undergraduate research conference held at UBC. The theme for MURC 2022 was Inspire Change. This theme seeks to approach research in a manner that inspires new generations to see that change as an agent of positivity and growth. The in-person components of the conference were held at the UBC Vancouver campus, with poster sessions in the Marine Drive Ballroom and oral presentations in the various lecture rooms in the West Mall Swing Space Building. Virtual presentations were held using the Zoom Meetings videoconferencing software.
Innovation Research on Fingerprint and DNA Identifications
Authors: Fei Jiaer
Published: April 2022

In this study, two models for fingerprint and DNA identifications are constructed based on modern technologies, while offering significant advances over prior models. Our models have high credibility, obtaining relatively accurate results under different circumstances. Under different assumptions, this model tests the probability of the validity in the statement that human fingerprints are unique to be 93.94%. In other words, the percentage of misidentification is 6.06%. This model is a robust fingerprint identification method that can tolerate highly nonlinear deformations. The model is tested on the basis of a self-built database, proving that the model has high credibility, and convincing results are obtained from sensitivity analysis. In order to estimate the odds of misidentification by DNA evidence, we emphasized on two factors that might contribute to misidentification: random match probability and the probability arising from laboratory errors. Then, a model is developed using Bayes’ theorem to reveal the inherent relationship between them, which carries some reference value. The probability of matching by DNA evidence is estimated based on the changes in the significant level. Finally, the probabilities of misidentification by both fingerprint evidence and DNA evidence are compared using numerous data. We found that the probability of the former is 6.06% and that of the latter is smaller than 4.0 x 10?10. Therefore, it can be concluded that DNA identification is far better than that of fingerprint identification.
