Determinants of Online Assessment Adoption in a Technical College

Higher education institutions have switched from the traditional paper-based assessment to online assessment in the last decade, and it is worthwhile to examine how the users have perceived such a change. While many technology acceptance studies focused on students as participants, this study examines the lecturers' perception of online assessment. The Unified Theory of Acceptance and Use of Technology model (UTAUT) has been widely adapted for technology acceptance studies, and it is suitable for the study on online assessment systems. Unlike the findings from the original UTAUT model, performance expectancy did not have a significant effect on behavioral intention. A new relationship was found between Social Influence and Use Behavior. The UTAUT was extended with Usability, Learnability and Attitude as additional constructs. An essential aspect of this study ascertained that attitude, a construct that was absent in the original model, has a significant effect on behavioral intention.
Improving size selectivity of round pot for Charybdis japonica by configuring escape vents in the Yellow Sea, China

Sustainable development of the important economic species, Asian paddle crab (Charybdis japonica), has attracted attention in the coastal waters of the Yellow Sea, China. The commonly used round pots are almost nonselective, resulting in severe bycatch of juveniles. In this study, we explored a method to improve the size selectivity for C. japonica by mounting escape vents on the side panels of each pot. The selectivity of pots with escape vent sizes of 70 mm × 20 mm, 70 mm × 25 mm, 70 mm × 30 mm, and 70 mm × 35 mm was tested using a catch comparison method. The estimated minimum landing size (MLS) of carapace height (27 mm), according to the regulated MLS of carapace length (50 mm), was used as a reference point to explain the results. Significant increases in the size of crabs caught by pots were found with the enlargement of escape vent size (Kruskal–Wallis test, P < 0.01). The pots with 70 mm × 20 mm, 70 mm × 25 mm and 70 mm × 30 mm escape vents released nearly 50%, 75% and 95% of undersized individuals, respectively, and these three types of pots retained approximately 90% of legal-sized individuals compared with the control pots without escape vents. The pots with 70 mm × 35 mm escape vents released nearly all undersized individuals, but they also released most legal-sized individuals. Pots with an escape vent size of 70 mm × 30 mm were recommended for the sustainable development of C. japonica in the Yellow Sea of China. The results of this study reiterate the importance of carapace height for determining the size selectivity, which can serve as a reference to formulate management regulations in the coastal waters of the Yellow Sea, China.

Inhibition Effect of Atenolol on Copper Corrosion in 1M HNO3: Experimental Study and DFT

Atenolol was examined as a copper corrosion inhibitor in 1M nitric acid solution using the mass loss technique and quantum chemical studies, based on density functional theory (DFT) at the B3LYP level with the base 6-311G (d,p). The inhibitory efficiency of the molecule increases with increasing concentration and temperature. The adsorption of the molecule on the copper surface follows the modified Langmuir model. The thermodynamic quantities of adsorption and activation were determined and discussed. The calculated quantum chemical parameters related to the inhibition efficiency are the energy of the highest occupied molecular orbital E(HOMO), the energy of the lowest unoccupied molecular orbital E(LUMO), the HOMO-LUMO energy gap, the hardness (η), softness (S), dipole moment (μ), electron affinity (A), ionization energy (I), absolute electronegativity (χ),absolute electronegativity (χ), fraction (ΔN) of electrons transferred from Atenolol to copper and electrophilicity index(ω). The local reactivity was analyzed through the condensed Fukui function and condensed softness indices to determine the nucleophilic and electrophilic attack sites. There is good agreement between the experimental and theoretical results.

Scale , abstraction , and connectionist models : On parafinite thresholds in Artificial Intelligence

In this thesis, I investigate the conceptual intersection between scale, abstraction, and connectionist modeling in arti cial intelligence. First, I argue that connectionist learning algorithms allow for higher levels of abstraction to dynamically emerge when para nite thresholds are surpassed within the network. Next, I argue that such networks may be surveyable, provided we evaluate them at the appropriate level of abstraction. To demonstrate, I consider the recently released GPT-3 as a semantic model in contrast to logical semantic models in the logical inferentialist tradition. Finally, I argue that connectionist models capture the inde nite nature of higher-level abstractions, such as those that appear in natural language. Index words: [Connectionism, Scale, Levels, Abstraction, Neural Networks, GPT-3] Scale, abstraction, and connectionist models: On parafinite thresholds in Artificial Intelligence
Experiments on invertebrate predation on cladocerans and its relationships with lake data

Until recently, knowledge of the impact of invertebrate predators on cladocerans in the Brazilian Lake Monte Alegre was limited to a few species. In order to assess the effects of predation on other cladoceran species, experiments were carried out with different pair-wise combinations of prey species. The experiments tested predation by fourth instar larvae of the dipteran Chaoborus brasiliensis Theobald on neonates and adults of the cladocerans Daphnia gessneri Herbst, Diaphanosoma birgei Kořínek, and Ceriodaphnia richardi Sars, and predation by the water mite Krendowskia sp. on neonates and adults of C. richardi and D. gessneri. In replicated treatments, the prey was offered alone or in combination with neonates and adults of two species and kept in bottles on a plankton wheel under controlled temperature, photoperiod, and light conditions. Chaoborus larvae preyed on neonates of D. birgei and D. gessneri and on adults of the former species. They preyed preferentially on neonates and adults of D. birgei over neonates and adults of C. richardi. The mite Krendowskia sp. preyed on only one species: neonates and adults of D. gessneri. Data on the distribution and strategies of prey in the lake are discussed in light of the experimental results, in an attempt to establish a link between laboratory data and field conditions.
Midkine as an Early Biomarker of Contrast-induced Acute Kidney Injury in Chronic Kidney Disease Patients Undergoing Percutaneous Coronary Intervention for Acute Coronary Syndrome: A Single-center Prospective Study

Background: Contrast-induced acute kidney injury (CI-AKI), is an important complication of percutaneous coronary intervention (PCI). We aimed to study the role of serum midkine (MK) as an early biomarker of CI-AKI. Methods: We conducted a prospective observational cohort study. It includes 100 chronic kidney disease (CKD) patients with an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m2. All patients were undergoing PCI for ACS. We measured serum midkine before, 2 and 24 hours after PCI. Results: The mean age of the patients was 70.32±3.62 years, 74% males. Twenty-seven patients developed CI-AKI. The CI-AKI group has a history of diabetes mellitus (DM) and/or dyslipidemia, history of diuretics, metformin and/or angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (ACEI/ARBs) use. The CI-AKI patients have low left ventricular ejection fraction (LVEF) (EF < 45%) and low Creatinine Clearance (CrCl) before PCI. The CI-AKI received more contrast volume, had a longer duration of PCI and had high Mehran risk score after PCI. Comparison between the two studied groups regarding serum MK showed that there was a statistically significant difference regarding serum MK 2 hours after PCI. Receiver operating characteristic (ROC) curve analysis for serum MK showed that serum MK measured 2 hours after PCI was statistically significant to predict CI-AKI. Conclusion: An early Serum MK after PCI can be used as an early predictor of CI-AKI in ACS patients.
Scrutinizing EFL Teachers’ Emotions in the Indonesian Context of Bandung

This study aims to investigate the most dominant emotions experienced by EFL teachers in the Indonesian context. Two kinds of questionnaires were employed in this study. This research involved participants of Bandung English Teachers. They were 72 EFL teachers who participated on the general scale of phase 1 and 68 EFL teachers who joined the specific scale questionnaire of phase 2. Three dimensions of emotions were explored in this research to know the level of emotions faced by teachers. Also, positive and negative emotions have been explored in this paper. A quantitative descriptive method was used to examine the data from two questionnaires as the main research instrument. This study adapted the Teacher Emotion Scale invented by Frenzel et al. (2016). The descriptive findings show that from two studies enjoyment is the most frequently experienced and anger is the lowest dimension of emotion preferred by EFL teachers. This study has proven the reliability of the research instrument. The research analysis shows that there is an insignificant difference between the two studies and both of them have a very close resemblance.
Sense of Humor in Student Task Discussion During Covid-19 Pandemic, Is It Important?

The government has established a Study-From-Home (SFH) program to prevent the spread of Covid-19. Implementing the SFH program is an alternative for students to continue to carry out online learning as a substitute for face-to-face meetings. Online task discussion through WhatsApp groups is a solution for completing common tasks which are considered quite effective. However, learning tasks during a pandemic were considered quite burdensome, such as increased stress levels. Previous studies show that increased stress and anxiety during SFH can be reduced through humor. This study conducts an argumentative literature review to determine the importance of humor in students learning during the covid-19 pandemic. This paper shows that humor in the task discussions has an essential role during the Covid-19 pandemic. With humor, it is expected that the level of students’ anxiety during the SFH program decreases. It is also expected to have a positive impact on the effectiveness of group communication in task discussions.
Study of carcinoma embryonic antigen and carbohydrate antigen 19-9 levels in patients of esophageal cancer

Background: The aim of the study was to analyze the role of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) as diagnostic and prognostic markers in patients of esophageal cancer. Various tumor markers are being investigated as non-invasive diagnostic and prognostic tools in patients of esophageal cancer.Methods: This was a prospective observational study in which we analyzed the levels of CEA and CA 19-9 in blood samples of 35 patients of esophageal cancer. All patients underwent esophagoscopy and computed tomographic (CT) scan to assess site and extent of tumor. Histological diagnosis was confirmed in all cases by endoscopy guided biopsy.Results: The sensitivity of CEA and CA 19-9 in detecting disease was found to be 34.3% and 28.6% respectively. The difference in CEA levels between squamous cell carcinoma and adenocarcinoma of esophagus was not found to be significant (p value=0.69). However, the difference in levels of CA 19-9 was found to be statistically significant (p value=0.02) between the two groups. The sensitivity and specificity of CEA to predict severity of disease was 66.7% and 70% respectively with positive and negative predictive value of 62.5% and 73.4 % respectively. In case of CA 19-9, sensitivity, specificity, positive and negative predictive values were 26.7%, 55%, 30.8% and 50% respectively.Conclusions: CEA was found to be a more sensitive diagnostic marker than CA 19-9 and better at predicting prognosis. However sensitivity and specificity of both were relatively low. CA 19-9 levels were seen to be higher in esophageal squamous cell carcinoma versus adenocarcinoma.

Biological activity In vitro, absorption, BBB penetration and toxicity of nanoformulation of BT44, a RET agonist with disease-modifying potential for the treatment of neurodegeneration

BT44 is a novel, second generation glial cell line-derived neurotropic factor (GDNF) mimetic, with improved biological activity and a lead compound for the treatment of neurodegenerative disorders. Like many other small molecules, it suffers from intrinsic poor aqueous solubility, posing significant hurdles at various levels for its preclinical development and clinical translation. Herein, we report a novel poly(2-oxazoline)s (POx) based BT44 micellar nanoformulation with ultra-high drug loading capacity of 47 wt. %. The BT44 nanoformulations were comprehensively characterized by 1H-NMR spectroscopy, differential scanning calorimetry (DSC), powder X-ray diffraction (XRD), dynamic light scattering (DLS) and cryo-transmission/scanning electron microscopy (cryo-TEM/SEM). The DSC, XRD and redispersion studies collectively confirmed that the BT44 formulation can be stored as a lyophilized powder and can be redispersed when needed. The DLS further suggested that the redispersed formulation is suitable for parenteral administration (Dh ≈ 70nm). The cryo-TEM analysis revealed the presences of worm like structures. The BT44 formulation retains biological activity in immortalized cells and in cultured dopamine neurons. The micellar formulation of BT44 exhibited improved absorption and blood-brain barrier (BBB) penetration and produced no acute toxic effects in mice. In conclusion, herein, we have developed an ultra-high BT44 loaded aqueous injectable nanoformulation, which can be used to pave way for its preclinical and clinical development for the management of neurodegenerative disorders.
BUILDING ROOF VECTORIZATION WITH PPGNET

Abstract. A challenge in data-based 3D building reconstruction is to find the exact edges of roof facet polygons. Although these edges are visible in orthoimages, convolution-based edge detectors also find many other edges due to shadows and textures. In this feasibility study, we apply machine learning to solve this problem. Recently, neural networks have been introduced that not only detect edges in images, but also assemble the edges into a graph. When applied to roof reconstruction, the vertices of the dual graph represent the roof facets. In this study, we apply the Point-Pair Graph Network (PPGNet) to orthoimages of buildings and evaluate the quality of the detected edge graphs. The initial results are promising, and adjusting the training parameters further improved the results. However, in some cases, additional work, such as post-processing, is required to reliably find all vertices.

Purpose: In order to implement Green Supply Chain Management (GSCM to support the effort in reducing the environmental impact of the supply chain processes, a framework needs to be developed. This study aimed to propose a conceptual and holistic GSCM framework to represents a roadmap towards GSCM implementation by integrating all green supply chain practices by various stakeholders of construction sector in Indonesia.Design/methodology/approach: Green practices were obtained from an extensive literature review. Questionnaire survey of GSCM stakeholders in the construction sector was conducted to obtain the preference of green supply chain variables as the proxy for variable weighting and ranking. Pairwise Comparison (PWC) and Technique for Others Preference by Similarity to Ideal (TOPSIS) were adopted to analyze the weight and to rank the green practices respectively. The finding of PWC and TOPSIS were used to develop the framework.Findings: The implementation of the GSCM in the construction sector in Indonesia is mainly focused on reducing the use of hazardous materials, the management of waste at the project site, selling products and components that are no longer used, using video conferencing both inter- and intra-organization meetings, and support from the management level in the form EMS and ISO 14001 certification.Research limitations/implications: This study did not include other GSCM performances as criteria, such as operational and logistical performance.Practical implications: An efficient evaluation technique developed by the framework can be used in decision making policies by policy makers and stakeholders of the organization which can identify and prioritize the green practices for adoption of GSCM in the construction sectorOriginality/value: The originality of this research is that GSCM framework was developed with most relevant green practices based on ranking and weighting criteria as well as the main stakeholders involved.
Role of Autophagy in Phosphatidyl- Glycerol Facilitated Cholesterol Clearance from the Endolysosomal System of Npc-1 Deficient Cells

Niemann Pick Type C (NPC) Disease is a rare lysosomal storage disorder in which one of the genes that codes for either the NPC-1 or NPC-2 pro-tein is mutated, causing cell lysosomes to accumu-late cholesterol and lipids. Previous studies discov-ered that a unique late endosomal/lysosomal phos-pholipid, lysobisphosphatidic acid (LPBA), is in-volved in cholesterol clearance from late endo-somes. It has also been shown that exogenous treat-ment of the NPC-1 deficient cells with LBPA’s precur-sor, phosphatidylglycerol (PG), leads to LBPA enrich-ment and subsequent endolysosomal cholesterol clearance. Autophagy is a mechanism of cellular clearance in the endolysomal system and we are in-terested to see if it is a partial route in cholesterol clearance during PG treatment of NPC-1 deficient cells. To do so, we silenced the gene that codes for an essential protein in the autophagy pathway, mak-ing the cells autophagy deficient. We then treated the cells with PG, measured the amount of choles-terol clearance in those cells, and compared it to cells with normal autophagy. We found significantly less cholesterol clearance by PG in cells with defec-tive autophagy, confirming that autophagy is in-volved as a partial route in cholesterol clearance dur-ing PG treatment, but not enough of a difference to conclude that it is a major underlying mechanism.
