The Use of Unmanned Aerial Vehicles (UAVs) in Slope Stability Assessment
Authors: Meeks Connor
Published: April 2021

The use and applications of unmanned aerial vehicles (UAVs) in geotechnical engineering is rapidly growing, leading to changes in the way that data is acquired, analyzed and processed. UAVs can reach areas previously inaccessible via ground or helicopter, while also being quickly deployed. Cameras are the current standard for data collection and 3D model creation.

There are multiple types of UAV’s currently available. Quadcopters can take off and land in spatially constrained areas, but carry a small stabilized camera producing low quality models. Octocopters permit an increased payload, so a higher quality camera can be attached, allowing for increased model accuracy. Flight time is reduced by the additional weight. Fixed wing UAVs create higher quality photogrammetry models, and are commonly deployed over large surface areas. Transport Canada certification must be approved prior to any flights occurring for research or work. A detailed application must be created, including a flight plan and demonstration of prior flight experience.

At the White Canyon site in B.C., a Phantom 4 Quadcopter was flown for geotechnical analysis of a complex geometry slope, which has previously been studied for several years. The terrain has occluded the data available from the ground or from permissible helicopter flight paths. Therefore, detailed information from the slope has not been previously available. The process of using a UAV to obtain these data sets, to develop a full 3D model of these areas of the slope is discussed, considering the accuracy and quality of the data available.
Investigating Tryptophan Hydroxylase Immunoreactivity in the Dorsal Raphe of Rats Exposed to Early Adversity
Authors: Intson Katheron
Published: April 2021

Prior studies link anxiety to alterations in serotonergic neurotransmission. Tao and Menard (unpublished data) found that female rats exposed to intermittent physical stress during early adolescence display greater levels of anxiety-like behaviours when tested as adults in social interaction tests. Interestingly, these behavioural changes were associated with changes in serotonin (5-HT) fiber density in the medial prefrontal cortex. Whether these changes in 5-HT fibre density are accompanied by changes in the number of 5-HT-producing cells in the dorsal raphe is not known. To examine this research question, tryptophan-hydroxylase (TPH) immunoreactivity (-IR) was used to label 5-HT cells in the dorsal raphe. Half the animals from the original adolescent stress study were exposed to IPS, and the remaining animals were handled only, serving as the control (CON) group. In adulthood, half of each of those groups were tested in the SI test. The remaining animals were not behaviourally tested, serving as home-cage controls (HCC). A two-factor analysis of variance will be performed with Treatment (IPS vs CON) and Testing (SI vs HCC) as the two factors. It is expected that, regardless of Testing, IPS rats will display higher levels of TPH-IR in the dorsal raphe than no-stress controls. The number of TPH-IR-positive cells will also be correlated with archival behavioural data. It is expected that that higher levels of TPH-IR will be associated with higher levels of anxiety-like behaviour. This study provides insights into the role that early adversity plays in shaping the structure and function of the brain’s serotonergenic system.
Skull Localization using Ultrasound for Navigated Neurosurgery
Authors: Underwood Grace
Published: April 2021

Image-guided navigation for neurosurgery requires accurate localization of the skull. Localization can be problematic when the patient is in a facedown position. The posterior skull lacks unique identifiable landmarks, which complicates standard localization methods using a tracked pointer. In addition to the lack of anatomical landmarks, trying to access facial surfaces is error-prone when working under the table and problems arise with line-of-sight of the optical tracker. We proposed the use of ultrasound to perform localization and investigated the accuracy of this process. A simulation study was performed to test the feasibility of ultrasound for localization on a plastic skull. An initial localization, using an optically tracked pointer, was performed to partially align pre-operative images and the skull model. Skull surface points were localized by optically tracked ultrasound and used in a surface registration algorithm. Accuracy and reproducibility was then investigated. Evaluation of the proposed localization method found that the average distance of points off the skull surface was 0.6 ± 0.1mm, which meets the same standards set by current commercially available systems for face-up positions. Using tracked ultrasound for registration is feasible for patients in facedown position. We provided a non-invasive method of registration that could be accomplished using one optical tracking camera, and maintains a constant line-of-sight. This project was performed in cooperation with Dr. Gernot Kronreif and the Austrian Center for Medical Innovation and Technology. Dr. Kronreif and his staff are preparing for a clinical test of this localization process.
Etruscan Dance Culture as Represented in Tomb Paintings from the UNESCO Heritage Site in Tarquinia (Italy)
Authors: Morgan Anthea
Published: April 2021

Karen Kain, recipient of the Companion of the Order of Canada and artistic director of the National Ballet of Canada, wrote an autobiography entitled Movement Never Lies referring to a truism about professional dance. The UNESCO heritage site of Tarquinia (Italy) featuring Etruscan tomb dance imagery has never been studied through Classical scholarship from the perspective of a professional dancer nor from the perspective of analysis of depiction of movement. The author of this presentation, a former dancer with the National Ballet of Canada (1986-1992) who is a Classics Major, has endeavoured to prove that examination of movement depiction can be used as evidence to provide insight into Etruscan culture. Methodology for the study is based on the premise that Etruscan dance representations of humans Ca. 2500 years ago and the techniques of the dancer of today reflect actions by the same species; therefore, a comparative is possible for the essence of the movement communicated.

Results of the study indicate that representation of the Etruscan dance language is realistic and stable, is organically derived, is immensely practical, and has unique features within the Mediterranean cultural milieu. This preliminary study highlights the possibility of using ancient Classical cultures as models and terms of comparison for better understanding aspects of modern societies. It is salient that in contemporary culture, woman and children are dying to dance (from eating disorders), while Etruscans seemed to be dancing to live or to become ambassadors for an afterlife indicated by the Etruscan models.
Exploring the Tinsel Prints of the Robertson Davies Collection
Authors: Zmijowskyj Ally
Published: April 2021

Like modern baseball or hockey cards, tinsel prints were collectable images of famous

actors and actresses produced in nineteenth century England. They could be purchased as singles or in sets of six or four, in colour or in black and white from. The purchaser could buy bags of prepared tinsel decorations along with the prints making them customizable. Thus, after the tinseling process, no two prints would be identical. This study focuses on the tinsel prints in the Robertson Davies Collection held at the W.D. Jordan Rare Books and Special Collections Library at Queen’s University. This research was conducted at the beginning of the campaign to conserve and rehouse the tinsel prints in from the Canadian author and playwright Roberston Davies’ personal collection. Each print was studied to determine the actor featured, the role they portray, the play this character is from, and the place each print has in the larger collection. The

tinsel prints from the Robertson Davies Collection were also compared to tinsel prints in larger collections such as The Museum of London, The Victoria and Albert Museum, and The Folger Shakespeare Library, to assess the individuality of each print. The findings of this research formed the foundation of an Omeka based website to showcase the outcomes as well as high resolution pictures. This publically accessible platform allows for those outside the Queen’s community to explore the Robertson Davies Collection and further their own knowledge on 19th century English theatrical ephemera.
The Impact of Health Literacy and Numeracy on Post-Transplantation Outcomes in Organ Transplant Recipients
Authors: Zhu Mary
Published: April 2021

Background: Patients referred for solid organ transplant with limited health literacy have been shown to be less likely to have access to transplantation. We examined the association between health literacy, health numeracy and post-transplant clinical outcomes (i.e. graft failure, non-adherence, readmissions, self-efficacy, or mortality).

Methods: A search of Medline for publications during the period January 1946 to July 2016 that examined health literacy, numeracy, and outcomes of transplant recipients. Titles and abstracts were independently examined by three reviewers for exclusion, and the full-text was then reviewed for inclusion.

Results: Of 247 citations, 12 met inclusion criteria including one review article and five randomized control trials (RCTs). Health literacy of recipients was measured using Newest Vital Sign (NVS) (n=2), 

Short Test of Functional Health Literacy in Adults (STOHFLA) (n=2), Rapid Estimate of Adult Literacy in Medicine (REALM-T) (n=1), and other knowledge questionnaires (n=5). Level of formal education was also examined as an assay of health literacy (n=3). Post-transplant outcomes were assessed through medication adherence (n=4), skin cancer incidence (n=2), graft loss (n=1), recipient mortality (n=1), kidney function (n=1), health-related quality of life (n=1), and self-efficacy (n=1). Eleven citations found limited health literacy to be associated with adverse post-transplant clinical outcomes, and one citation found no association between health literacy and non-adherence. Health numeracy was not studied in any of the citations.

Conclusion: Health literacy is negatively associated with adverse post-transplant clinical outcomes. Future studies should analyze the association between health numeracy and clinical outcomes after transplant.
5. Determining Groundwater Inputs into High Arctic Lakes (Cape Bounty, Melville Island, NU)
Authors: Harasyn Maddie
Published: April 2021

The focus of this research project is to determine the presence of groundwater seepage within two High Arctic lakes located in continuous permafrost on Melville Island, NU. Small isolated depressions were located at the bottom of each lake using bathymetric data – 21 in East and West Lake (unofficial names) combined. It was hypothesized that these depressions could be the sites of groundwater seepage into the lakes, and these locations then served as sample sites for CTD cast and water sample collection during the 2016 field season. Water chemistry and physical property data were used as indicators of groundwater seepage, as ground water would have properties similar to the source of the ground water, generating a change in water chemistry at each of these sites.

Ionic analysis has showed site specific change at the bottom of both lakes, related to the underlying bedrock structure. Ionic ratios for the northern sites differ from ratios of the rest of the sample sites, as well as the ambient water of each lake. This correlates with the meeting of two geologic units within both lake limits. Physical characteristic data showed no change within East Lake and a localized change within West Lake, represented as an increase in electrical conductivity and decrease in dissolved oxygen. These results suggest that highly localized groundwater seepage is likely occurring in these High Arctic lakes, and that water property influences to ground water may be even more highly localized.
11. What’s in a Loaf? A Bio-accessibility Study of Toxic Elements in Gluten-free and Rye Breads and the Effect of Toasting Bread on the Bio-accessibility of those Elements Using ICP-MS
Authors: Kierulf Alastair
Published: April 2021

Bread is a staple in the North American diet with over 4 million tonnes consumed in the US annually. The popularity of breads made from alternative grains (such as rye, quinoa, and pumpernickel) and the increase in gluten free (GF) alternatives (made from a mixture of rice and other alternative grains) has significantly contributed to this growth[1] While the hunger for alternative breads is increasing, there is little research into the risks associated with consuming breads made from alternative grains. Studies[2] have shown that many grains can contain high levels of toxic elements, especially if they are grown in soils with high levels of these elements.

A previous study [3] investigated the risk associated with toxic elements in rice, and concluded that these elements are highly bio-accessible when the rice is not washed before processing. It is therefore extremely important to investigate the risk and bio-accessibility of toxic elements in these popular alternative breads.

Two different alternative breads were analyzed for their toxic element compositions, and the bio-accessibility of these elements was investigated. Results showed that the gluten free breads contained high concentrations of arsenic and selenium, and little to no levels of cadmium or lead. Rye bread, in comparison, contained little arsenic, cadmium, or selenium which was consistent with previous studies. Further work will investigate the effect of toasting and will also utilize an innovative online leaching method that significantly improves bio-accessibility results [3,4].

Published: April 2021

Genus Aconitum (Ranunculaceae) is represented by 6–8 species from Kashmir Himalaya.  Traditionally Aconitum species are used to treat a wide array of diseases, but their ethnopharmacological validation and phytochemistry are hitherto unreported from Kashmir Himalaya. The present study was undertaken to bring insights into the traditional use and distribution pattern of three Aconitum species from the region. An ethnobotany-directed approach was employed to study the conservation status of three Aconitum species. Their phytochemical profiles and biological properties were screened under in vitro conditions. Folin–ciocalteu and Aluminium chloride assays were employed to measure their total phenolic and total flavonoid contents, respectively. Plant extracts were evaluated for antioxidant, antimicrobial and anti-inflammatory activities. Three Aconitum species, viz. Aconitum heterophyllum Wall. ex Royle, Aconitum violaceum Jacquem. ex Stapf and Aconitum chasmanthum Stapf. ex Holmes showed dwindling conservation status in Kashmir Himalaya. Aconitum extracts showed significant variations in total phenolic and flavonoid contents. Antioxidant activity of Aconitum chasmanthum methanolic extract was studied to be comparatively higher (80.115%). Aconitum chasmanthum DCM & methanolic extracts showed a good MIC value of 0.125 mg/ml against Candida albicans and Streptococus pyogenes, respectively. The percent inhibition of NLRP inflammasome was found significant in Aconitum violaceum ethyl acetate extract (74.61%). The present study revealed that Aconitum species are constantly declining at least in investigated habitats of Kashmir Himalaya and hence need strategic conservation planning. The results also emphasized the utility of Aconitum species as an antioxidant, antimicrobial and anti-inflammatory agent that could be used to manage various health problems.

Published: April 2021

Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative HPLC and their structures were established to be 8-hydroxyperrottetin F, C-7-C-8 cleaved product, and perrottetin F 6’-sulfate using 1D and 2D NMR, HR-ESI-MS, IR and UV spectroscopy. The antimicrobial and cytotoxic properties of these compounds were also evaluated. Given the suggested cytotoxic properties of the parent compound, antiproliferative activity against healthy human lung fibroblasts (MRC5) and human lung carcinoma (A549) of three metabolites were evaluated revealing their lower cytotoxic properties in comparison to the starting compound - perrottetin F. The antimicrobial properties of these compounds were also evaluated, with the inhibitory activity against the Pseudomonas aeruginosa PAO1 and Staphylococcus aureus determined between 100 µM and 450 µM. The metabolites showed remarkable ability to inhibit synthesis of bacterial quorum-sensing signal molecules such as short chain acyl homoserine lactones (AHLs). Therefore, biotransformation method represents fast and effective tool for obtaining new bioactive structures.

The hydrodistilled volatile constituents of Cistanche tubulosa (commonly known as Desert Ginseng) have been chemically and biologically investigated. Based on the retention times and mass fragmentation of the obtained GC-MS chromatogram, 106 individual components which representing ≈ 99.29 % of the total volatile constituents have been identified. The major compounds (66.57% of the total composition) were identified as hexanal (15.98%), trans-sabinyl acetate (12.22%), allo-aromadendrene (9.30%), nonanoic acid (6.66%), 3Z- hexeny-2-methyl butanoate (6.09%), valeranone (5.25%), (E, E)-α-Farnesene (3.18%), a-pinene (3.06%), linalool isovalerate (3.03%) and a-humulene (1.8%). Estimation of the antioxidant activity of EO showed promising effect at 80 mg/mL concentration, it exerted 62.40, 863.29 and 62.72 % inhibition compared to TBHQ that showed 78.62, 77.56 and 79.23 % inhibition using DPPH, ABTS and β-carotene/Linoleic acid, respectively. The antioxidant activity was pronounced at 80 mg/mL than other concentrations. The volatile constituents showed inhibitory activity against gram positive bacteria ranged from 2.23 mg/100 mL ( for staphylococcus aureus ), and 15.68 mg/100 mL (for Bacillus cereus) compared to ciprofloxacin which showed inhibitory activity 0.185, and 0.182 mg/100 mL, respectively. Moreover, the MIC of volatiles towards gram negative bacteria are ranged from 18.35 (Escherichia coli) to 31.61 mg/100 mL (Klebsiella pneumonia) compared to ciprofloxacin with 0.184 to 0.188 mg/mL respectively. Additionally, the antifungal activity against candida albicans was rather promising (4.36 mg/mL).

Dual-energy Computed Tomography Delayed Myocardial Enhancement in the Diagnostic Dilemma of True versus False Left Ventricular Aneurysm – A Case Report
Authors: Berecova Zuzana , Juskanic Dominik , Simkova Jana , Simkova Iveta
Published: April 2021

The aim of this case report is to show the capability of cardiac computed tomography (CT) in combination with dual-energy CT (DECT) delayed myocardial enhancement to support diagnostic decision making in the complicated differential diagnosis of true versus false left ventricle (LV) aneurysm, as well as provide additional information that can influence overall patient outcome. We present a 71-year-old obese patient with metabolic syndrome, stable chronic coronary syndrome with three-vessel disease, and recent chest discomfort. His coronary angiogram showed no significant coronary artery stenosis, but suspicion of LV apical pseudoaneurysm was expressed. Neither transthoracic nor transesophageal echocardiography was able to dismiss this suspicion. Consequently, coronary CT angiography (CCTA) followed by DECT delayed myocardial enhancement was performed. Findings on CCTA and DECT confirmed the diagnosis of a true aneurysm. Moreover, fibrotic changes within the hypertrophic myocardium were visualized. This finding will influence further patient therapy as well as the outcome. DECT delayed myocardial enhancement can be an important complementary tool for distinguishing true versus false LV aneurysms. Moreover, it can provide additional information for making complex diagnose. Adding DECT delayed myocardial enhancement to CCTA can replace cardiac magnetic resonance imaging evaluation in certain settings.

Published: April 2021

Cells modulate their homeostasis through the control of redox reactions via transmembrane electron transport systems. These are largely mediated via oxidoreductase enzymes. Their use in biology has been linked to a host of systems including reprogramming for energy requirements in cancer. Consequently, our ability to modulate membrane redox systems may give rise to opportunities to modulate underlying biology. The current work aimed to develop a wireless bipolar electrochemical approach to form on-demand electron transfer across biological membranes. To achieve this goal, we show that using membrane inserted carbon nanotube porins that can act as bipolar nanoelectrodes, we could control electron flow with externally applied electric fields across membranes. Before this work, bipolar electrochemistry has been thought to require high applied voltages not compatible with biological systems. We show that bipolar electrochemical reaction via gold reduction at the nanotubes could be modulated at low cell-friendly voltages, providing an opportunity to use bipolar electrodes to control electron flux across membranes. Our observations present a new opportunity to use bipolar electrodes to alter cell behavior via wireless control of membrane electron transfer.

Authors:   University of Malaya, Malaysia, Abd Kadir Muhamad Fadzly
Published: April 2021

The purpose of this paper is to propose a conceptual framework on the individual factors, situational factor and individual work performance of logistician working at the Royal Service Corps in the Malaysian Army. The current paper is intended to examine the relationship between individual and situational factors and their impact on individual work performance. Moreover, individual factors which are “openness to experience and social intelligence” and a situational factor which is “workplace relationship” have been used as independent variables. Individual ambidexterity acts as a mediating variable, while the extent of change acts as a moderating factor. The dependent variables in this study are individual work performance focusing on the dimensions of the task and adaptive performance. Theory of Work Performance and the Burke-Litwin Model are used to define concepts and explain the phenomena. It is assumed to form a significant relationship between employee capacity, willingness and opportunity towards performance and organisational environments are perceived and interpreted by their employees. Findings from this study have implication for the selection process, mixture and redeployment of personnel; training and competency development; and overall organisation improvement.
Transition towards a sustainable heating sector in municipality of Visoko with analysis of loading and optimization of solar collector carriers
Authors:   University of Sarajevo
Published: April 2021

Many traditional heating systems based on fossils face challenges such as lack of investment or unfavorable price regulation, low technical performance, impact on the environment and negative consumer perceptions. The CoolHeating project funded by the EU’s Horizon 2020 program, whose basic features and outcomes are presented in this work, promotes the implementation of small modular renewable heating and cooling grids for communities in South-Eastern Europe, including the town of Visoko as one of five target regions. Core activities, besides techno-economical assessments and social-environmental benefits, include measures to stimulate the interest of communities and citizens to set-up renewable district heating systems. In this work, an analysis was performed for implementation of small modular district heating system in Visoko, covering several public buildings and few neighborhoods in north-western part of town. Combination of different renewable energy sources were analyzed leading to an optimal and a very promising energy supply strategy due to its contribution to security of supply, financial stability, local economic development, local employment, etc. Possible financial savings for heating of 38% compared to current financial needs are determined. Structure optimization of solar collector holders was also performed, taking into account external influence, enabling savings in the structure material. This approach confirms feasibility of transition from traditional to renewable energy based heating system. Having in mind the modularity of such systems, similar solutions can be replicated in other South-Eastern European cities and other countries.

Published: April 2021

Halal industry is currently one of the fastest growing market segments in the world. With the emerging of IR4.0, the future growth of Halal industry and its sustainability can be affected by the advancement of technology. Technology has continuously assimilated in every aspect of our live from consumerization, commercialization, and industrialization to infrastructure. Even though many factors may have collectively contributed towards better understanding of Halal sustainability, this article focuses only on the technological aspects of Halal in the face of IR4.0. With this focus, four components of technology comprising of technoware, humanware, infoware, and orgaware are discussed. Although each components of technology have been fairly studied in the previous Halal literature, most of them were not specifically emphasized on the sustainability issues. From DCs point-of-view, a firm that is capable of managing the complexity in the components of technology will become more sustainable at Halal marketplace under dynamic environment. A framework is proposed to explain how the technology complexity together with the environmental factors (opportunities and threats of IR4.0) can be affecting Halal sustainability. This article has proposed the complexity in each components of technology will positively affect Halal sustainability. Accordingly, the opportunities of IR4.0 is proposed to have a positive direct and moderation effects on the relationships between technology complexity and Halal sustainability, whereas the threats of IR4.0 will have a negative direct and moderation effects on the relationships.

Studiu privind activitățile de prevenire a tulburărilor de limbaj în grădinițe
Authors: ROȘCA Simona Bianca
Published: April 2021

The present research starts from the idea of preventing language disorders from an early age, given the results of previous research on the effectiveness of early interventions.
Following a preliminary documentation that consisted in the study of Romanian legislation, specialized literature, speech therapy aids, speech therapy software, sites with medical profile and special pedagogy, it was found an insufficient approach to prevention and we wanted to investigate what activities speech therapy teachers consider to be included in the concept of prevention. We also sought to find out to what extent speech therapists take into account the prevention part and what activities they carry out for this purpose. The results were limited and we see them from at least two perspectives: the small group of participants that led to limited data and the absence or quasi-absence of prevention in speech therapy, this being too little described in the literature and outlined as a methodology in school documents. The most common options chosen by language therapists for prevention were to carry out speech therapy activities in prevention groups under the age of 5 and to carry out information activities for educators and parents and only then screening activities

Published: April 2021

Performing the Critical Chain Scheduling (CCS) and Buffer Management (BM) in project management has recently risen as one of the most popular project management approaches. The critical Chain Scheduling (CCS) approach is replacing the traditional scheduling method to reduce the uncertainty associated with time schedules. The research highlights the importance of critical chain scheduling in project execution by investigating using buffers in the critical paths and the feeding baths in project management using a real case study. The case study was studied by analyzing the schedule provided and then implementing CCS and BM using four different methods. The methods are cut and paste (C&PM), the root square method (RSEM), the Adaptive procedure with resource tightness, and the Adaptive procedure with network density (APND). The buffer size obtained for each method was determined. From the result got, for project buffer in adaptive approach with network density method yields a larger buffer size compared to the adaptive procedure with resource tightness method. While for feeding buffer also show that APND resulted in a larger buffer size than APRT. Finally, the proposed buffer size was investigated and simulated using the What if approach.

Usaha pemanfaatan limbah kulit udang sampai saat ini belum maksimal, padahal dalam kulit udang terdapat senyawa yang sangat bermanfaat yaitu khitin. Kandungan khitin dalam kulit udang pada umumnya sekitar 20%. Khitin merupakan sumber polisakarida potensial dan mulai dikembangkan untuk aplikasi di bidang agrikultur, biomedis, farmasi, bioteknologi dan proses pemisahan dengan membran. Khitin adalah polimer alam sejenis polisakarida yang mempunyai berat molekul rata-rata 1,2.105 g/mol dan nama kimia 2 — Asetamida — 2 — deoksi — D — Glukopiranosa

Pada kulit udang, khitin bergabung dengan mineral dan protein dalam fasa padat. Untuk mendapatkan khitin maka campuran tersebut dipisahkan dengan cara ekstraksi dengan menggunakan pelarut cair (Ekstraksi Padat Cair). Pada proses ekstraksi ini terdapat reaksi demineralisasi dan reaksi deproteinasi. Kandungan mineral utama yang terdapat pada kulit udang adalah CaCO3, yang dapat dihilangkan dengan cara direaksikan dengan larutan HCI. Reaksi ini berjalan secara maksimum pada konsentrasi larutan HCI 1 M, temperatur operasi 70oC, waktu reaksi 1 jam.

Setelah proses demineralisasi, kulit udang tersebut diharapkan hanya mengandung protein dan khitin. Ekstraksi dilanjutkan ketahap deproteinasi untuk menghilangkan protein yang banyaknya sekitar 28%. Protein ini dapat dihilangkan dengan cara direaksikan dengan larutan NaOH. Reaksi berjalan secara maksimum pada konsentrasi larutan NaOH 4 M, temperatur operasi 70oC, waktu reaksi I jam. Setelah melalui proses tersebut maka didapatkan khitin dengan perolehan sekitar 17,5%.

Kompleksitas Query Database dalam suatu sistem semakin meningkat seiring pertumbuhan data. Kompleksitas Query Database yang meningkat mengakibatkan kerumitan dalam mendapatkan data yang sesuai dengan kebutuhan. Insinyur perangkat lunak telah mengedepankan banyak metriks untuk meningkatkan kualitas dari program perangkat lunak, mengabaikan Query Database yang digunakan. Sehingga belum ada metriks yang dapat mengukur tingkat kerumitan dalam mendapatkan data. Padahal aspek data pada perangkat lunak penting karena ukuran data berkontribusi pada banyak kualitas sistem. Paper ini menggunakan metode GQM untuk mengidentifikasi metriksnya. Paper ini mengidentifikasi bahwa metriks untuk sebuah Query Database meliputi jumlah tabel, kolom, statement, kedalaman dan fungsi logika. Dari beberapa formula kompleksitas yang sudah pernah diajukan, kami hanya menghitung dari statement select dan diformulasikan dengan metode Analytic Hierarchy Process (AHP).

Organisasi merupakan suatu kelompok yang terdiri dari sekumpulan orang dalam satu wadah untuk mencapai tujuan bersama. Suatu Organisasi dapat dikatakan berkembang apabila memenuhi beberapa aspek contohnya seperti struktur organisasi dan proses bisnis yang dijalankan. Pada penelitian ini kami menggunakan studi kasus pada permainan Hay Day yang bertujuan untuk mencari pertumbuhan organisasi pada permainan Hay Day dimana pada permainan Hay Day semakin bertambahnya level maka struktur organisasi dan proses bisnis yang dijalankan semakin besar. Maka dari itu pengukuran dilakukan berdasarkan level sebagai parameter variabel bebas kemudian mencari metric kompleksitas pada struktur Organisasi yang telah dibentuk. Metode perhitungan yang digunakan yaitu dengan menggunakan metode perhitungan Graph. Langkah selanjutnya yatiu melakukan perhitungan dengan metode regresi untuk menemukan pertumbuhan dari struktur Organisasi pada permainan Hay Day. Hasil perhitungan dari regresi linier menunjukkan bahwa pengukuran pertumbuhan struktur organisasi pada permainan Hay Day diperoleh R2 bernilai 97,8%.

Aplikasi komputer meningkat jumlahnya dan menjadi lebih kompleks seiring dengan pertumbuhan bisnis dan ilmu pengetahuan. Dalam hal ini, pengelolaan dan integrasi data menjadi sangat penting. Pengembangan Web Service semakin meningkat. Pengembang Web Service membutuhkan banyak data riset dan referensi mengenai kompleks atau tidaknya suatu Web Service berkaitan dengan perkiraan biaya pengembangan, batasan waktu pengerjaan, dan sumber daya yang dibutuhkan untuk pengembangan, termasuk spesifikasi komputer dan sumber daya manusianya. Setiap pengukuran yang dilakukan dibutuhkan tersedianya ukuran kuantitatif yang disebut metrik, yang selanjutnya akan menghasilkan output berupa kompleksitas dari Web Service. Atas dasar itu, diperlukan sebuah perangkat lunak yang dapat menghitung metrik skala dan kompleksitas Web Service dengan cara meng-import file bertipe xml document dan berisi dokumen WSDL (Web Service Description Language) yang digunakan untuk menggambarkan kompleksitas Web Service berdasarkan pengukuran Data Weight (DW) yang dihitung dari bobot Argument per Operation (APO) dan Operation per Service (OPS). Dari percobaan perhitungan kami secara manual terhadap suatu dokumen WSDL, dimunculkan beberapa hasil berupa banyaknya argumen, OPS, dan APO. Hal ini kami terapkan pada perangkat lunak dan menghasilkan proses perhitungan yang lebih cepat. Pengguna dapat meng-import document tipe .xml dan hasil kompleksitas Web Service akan dimunculkan dalam aplikasi. Ukuran metrik dan kompleksitas yang diperoleh dapat digunakan untuk memperkirakan manajemen pengembangan Web Service.

The research aim is to identify differences in body composition between physically inactive persons and students of the Faculty of sport and physical education. The sampleconsisted of 32 people (16 men and 16 women) with an average age of 24.6 ± 3.3 years. Body composition measurements were performed using bioelectrical impedance (BIA)method using an electric scale, bioimpedance (In Body 720). The MANOVA and t-test results showed that there were no statistically significant differences in body compositionbetween physically inactive persons and students of the Faculty of sport and physical education (F = 0.778; p = 0.595). The obtained results could indicate the shortcomings ofthe curriculum at the Faculty of sport and physical education, whose contents, intensity and/or volume do not sufficiently stimulate the student body, as well as the failure ofstudents to fulfil extracurricular obligations and their poor health habits.
