Visual content analysis of visitors’ engagement with an instagrammable exhibition

ABSTRACT This study aims to show how a museum exhibition designed to encourage visitors to take pictures can affect visitors’ behavior. We analyzed visitors’ engagement with the Yumi's Cell Special Exhibition (hereafter Yumi) held in South Korea, employing computer vision for the analysis of visitors’ Instagram pictures. Our research questions are: What types of pictures do visitors post on Instagram during or after their visit? And can Yumi’s instagrammable features make visitors interact more with the exhibition? We also formulated two corresponding hypotheses: Visitors are primarily interested in taking selfies in the instagrammable environment; and visitors struck more active poses when taking pictures in an instagrammable exhibition than in a traditional art exhibition. Through the image analysis of Instagram posts of the exhibition, we found many pictures of people, but the proportion of selfies was relatively limited. This suggests that visitors were more interested in interacting with the exhibition rather than taking selfies. This has also been confirmed by the pose analysis, which showed that the participatory feature of the exhibition encouraged visitors to take photos in active poses, interacting, mimicking, and performing. The framework presented and the findings offer insights about how to design exhibitions to increase visitors’ participation.
Side Channel Information Leakage: Design and Implementation of Hardware Countermeasure

Deployment of Dynamic Differential Logics (DDL) appears to be a promising choice for providing resistance against leakage of side channel information. However, the resistance provided by these logics is too costly for widespread area-constrained applications. Implementation of a secure DDL-based countermeasure also requires a complex layout methodology for balancing the load at the differential outputs. This thesis, unlike previous logic level approaches, presents a novel exploitation of static and single-ended logic for designing the side channel countermeasure. The proposed technique is used in the implementation of a protected crypto core consisting of the AES “AddRoundKey” and “SubByte” transformation. The test chip including the protected and unprotected crypto cores is fabricated in 180nm CMOS technology. A correlation analysis on the unprotected core results in revealing the key at the output of the combinational networks and the registers. The quality of the measurements is further improved by introducing an enhanced data capturing method that inserts a minimum power consuming input as a reference vector. In comparison, no key-related information is leaked from the protected core even with an order of magnitude increase in the number of averaged traces. For the first time, fabricated chip results are used to validate a new logic level side channel countermeasure that offers lower area and reduced circuit design complexity compared to the DDL-based countermeasures. This thesis also provides insight into the side channel vulnerability of cryptosystems in sub-90nm CMOS technology nodes. In particular, data dependency of leakage power is analyzed. The number of traces to disclose the key is seen to decrease by 35% from 90nm to 45nm CMOS technology nodes. Analysis shows that the temperature dependency of the subthreshold leakage has an important role in increasing the ability to attack future nanoscale crypto cores. For the first time, the effectiveness of a circuit-based leakage reduction technique is examined for side channel security. This investigation demonstrates that high threshold voltage transistor assignment improves resistance against information leakage. The analysis initiated in this thesis is crucial for rolling out the guidelines of side channel security for the next generation of Cryptosystem.
The Factors Affecting the Adoption of e-PACRA Services through the Government Service Bus

The study was conducted to establish the factors affecting the adoption of e-PACRA services through the Government Service Bus. The UTAUT model was used as the conceptual framework to generate five hypotheses and the survey questionnaires which were analyzed after data collection and findings. The study assessed challenges of e-PACRA services on the Government Service Bus under the Smart Zambia Institute in order to ascertain and identify whether adoption of electronic services was affected by the five constructs of the UTAUT Model. The Cochrane’s Formula was used to derive the sample size of 132. The survey location for the study was Lusaka City in Zambia. Both qualitative and quantitative data were collected from respondents at a 100% response using the structured questionnaire. The output of the data was analyzed by SPSS and the ANOVA test was used to determine the relationship between variables. Three out of the 5 hypotheses were accepted as they showed a statistical relationship between the variables. The measure of the p-value was at ≤0.05.
Crosstalk-free operation of multi-element SSPD array integrated with SFQ circuit in a 0.1 Watt GM cryocooler

We demonstrate the successful operation of a multi-element superconducting nanowire single-photon detector (SSPD) array integrated with a single-flux-quantum (SFQ) readout circuit in a compact 0.1 W Gifford-McMahon cryocooler. A time-resolved readout technique, where output signals from each element enter the SFQ readout circuit with finite time intervals, revealed crosstalk-free operation of the four-element SSPD array connected with the SFQ readout circuit. The timing jitter and the system detection efficiency were measured to be 50 ps and 11.4%, respectively, which were comparable to the performance of practical single-pixel SSPD systems.
The impact of green marketing tools on green product purchase behavior: the moderation effect of consumer demographics

Purpose: The green concept has become a major concern of the modern world when consumers buy a product. Sri Lankan consumers also change their purchasing behavior toward green purchases. Even though environmental actives influence humans and firms’ behavior very significantly, very limited academic disciplines have integrated the selected phenomenon into their literature especially true of marketing. Thus, this study focuses on whether Environmental Advertisements, Perception of Eco-labels, and Perception of Eco Brands impact on green purchasing behaviour. Design/methodology/approach: The present study empirically tests the theoretical model in social-ecological paradigm association with green advertising tools and green purchase behavior. A survey of 150 consumers who used electronic home appliances is conducted as a self-administrated questionnaire. Findings: According to the findings, green marketing tools positively impact Green Purchasing Behavior in the electronics home appliances market. Further, the moderation effects make sure consumer demographics such as gender and education level have significant effects on the green behavior of the electronic home appliances market, but the different marketing tools are different. Originality: This study provides penetrations into studying the impact of green marketing tools on consumer purchasing behaviour with consumer demographics and motivation to purchase green electronic home appliances. Implications: This study provides insights to marketers to use Environmental Advertisement, Eco-Labeling system, and Eco Brand System to motivate the customers to buy the green products. The green marketers can establish a uniform Eco-Label system with the support of the government. Further, the marketers can enhance customer awareness regarding the standardized Eco Label using the Environmental Advertisement. Keywords: Eco-Brand, Eco-Label, Environmental-Advertisement, Green Marketing Tools, Green Purchasing Behaviour
Some Further Results on Fixed-Time Synchronization of Neural Networks with Stochastic Perturbations

In this paper, fixed-time (FXT) synchronization issue of a type of neural networks (NNs) with stochastic perturbations is considered. First, we obtained some novel sufficient criteria to guarantee the FXT synchronization of considered networks via introducing two types of controllers and employing some inequality techniques. Lastly, our theoretical results are verified via giving two numerical examples with their Matlab simulations.
Characterizing and understanding the growing population of socially engaged engineers through Engineers Without Borders-USA

Background – The engineering field is concerned with needs for more engineers, diversity, and globally prepared engineers; however, theory suggests that these challenges indicate a more central challenge, that is, the misalignment between engineers’ personal values and their vocations. At the same time, socially engaged engineering activities do not appear to experience the same challenges, which suggests their success at aligning personal values and vocations for a broader group of engineers. Purpose/Hypothesis – This research investigates the similarities and differences in personal values for engineers both involved and not involved in one of the most prominent engineering service organizations in the US, Engineers Without Borders (EWB-USA). Design/Method – Using a sequential mixed-method approach that combined variableoriented analysis of interviews and focus groups with 165 engineers with multiple logistic regression models from responses to a national survey of over 2,000 engineers, we compared and contrasted engineers’ personality traits and motivations to study engineering. Results – Results indicated that EWB-USA members and non-members both exhibited strong engineering personality traits and intrinsic engineering interests and motivations; however, results also indicated that EWB-USA members showed significantly stronger personality traits for openness to experience and agreeableness, higher motivations for social good, and broader interests than non-members.
Design and Development of Unibody Quadcopter Structure Using Optimization and Additive Manufacturing Techniques

Quadcopters represent rotary wing configuration of the Unmanned Aerial Vehicles (UAVs) with immense application potential in industrial and strategic contexts. Tradeoff between flight endurance and payload capacity renders design optimization of UAVs a critical activity with substantial impact on the application possibilities. Among the structural parts of a typical Quadcopter, the central body frame constitutes major portion of the total weight. The present study aims at reduction of the frame weight while conforming with structural integrity requirements, through an integrated approach involving topology optimization, part consolidation and design for additive manufacturing (DFAM). Commercial UAV designs consist of multiple parts and fastening elements that necessitate considerable time and effort for assembly. This study reengineers the frame as a monocoque structure with desirable outcomes of weight reduction and less assembly time. The reengineered Quadcopter structure is manufactured through Fused Filament Fabrication (FFF) and characterized with reference to structural, vibrational and fatigue characteristics. Concomitant application of modal analysis, computational fluid dynamics and wind tunnel testing reveals close match between theoretical estimates and experimental results. Assembly and field trials of the monocoque Quadcopter structure affirm betterment of operational superiority and endurance vis-a-vis commercial UAV designs.
Variations in Rainbow Trout Immune Responses against A. salmonicida: Evidence of an Internal Seasonal Clock in Oncorhynchus mykiss

Simple Summary Our bodies run on an internal schedule or clock, telling us when to rest, sleep, or digest, and when to wake up, be active, or burn calories. That’s why we experience jetlag because we may well set our watches forward or backward, but our bodies haven’t yet. Imagine a seasonal clock that helps get us through the year, not just through the day. We set out to prove that such a clock exists in fish just like it does in humans. We exposed rainbow trout to bacteria to imitate natural encounters. We raised fish in the laboratory under the same light and temperature all year long. When we tested them in summer and winter, the fish consequently experienced days that were artificially longer/shorter or warmer/colder. Nonetheless, certain fish white blood cells didn’t react or see the bacteria as a threat in winter unlike in summer. They were probably behaving based on the time of year, or season and not on their immediate environment, just like how a jetlagged individual behaves based on an internal clock, not on what it’s like outside. Immunity and other processes are regulated differently between seasons, making animals less or more vulnerable in summer or winter. Abstract In poikilothermic vertebrates, seasonality influences different immunological parameters such as leukocyte numbers, phagocytic activity, and antibody titers. This phenomenon has been described in different teleost species, with immunological parameters peaking during warmer months and decreased levels during winter. In this study, the cellular immune responses of rainbow trout (Oncorhynchus mykiss) kept under constant photoperiod and water temperature against intraperitoneally injected Aeromonas salmonicida during the summer and winter were investigated. The kinetics of different leukocyte subpopulations from peritoneal cavity, spleen, and head kidney in response to the bacteria was measured by flow cytometry. Furthermore, the kinetics of induced A. salmonicida-specific antibodies was evaluated by ELISA. Despite maintaining the photoperiod and water temperature as constant, different cell baselines were detected in all organs analyzed. During the winter months, B- and T-cell responses were decreased, contrary to what was observed during summer months. However, the specific antibody titers were similar between the two seasons. Natural antibodies, however, were greatly increased 12 h post-injection only during the wintertime. Altogether, our results suggest a bias toward innate immune responses and potential lymphoid immunosuppression in the wintertime in trout. These seasonal differences, despite photoperiod and water temperature being kept constant, suggest an internal inter-seasonal or circannual clock controlling the immune system and physiology of this teleost fish.
Adolescents’ sexual and reproductive health education: perspectives from secondary school teachers in Northern Nigeria

ABSTRACT Lack of sexual and reproductive health (SRH) education contributes to poor SRH outcomes for adolescents and young people in Sub-Saharan Africa. School-based comprehensive SRH education programmes in low- and middle-income countries aim to advance gender equality and human rights and reduce risky sexual behaviours in adolescents. However, the implementation of these programmes in Northern Nigeria is opposed by community and religious institutions because of mistrust of health interventions perceived as being framed on Western ideologies. This study explored perceptions of such programmes among secondary school staff in Northern Nigeria. We focused on knowledge and beliefs about comprehensive SRH education programmes, and views about barriers to delivery and ways to support their inclusion in schools. Sixteen semi-structured in-depth interviews were conducted with teachers and head teachers. Participants were aged 33–54 years and came from four public secondary schools in two states (Kano and Jigawa). Findings showed conflicting gender-based perspectives on the importance of comprehensive SRH education in schools. Barriers to delivery included lack of adequate skills and knowledge, beliefs/cultural norms and wider societal barriers. Involving traditional and religious leaders and schools in the design of tailored approaches could strengthen future delivery.
Effects of Dietary Fat to Carbohydrate Ratio on Obesity Risk Depending on Genotypes of Circadian Genes

Although the impacts of macronutrients and the circadian clock on obesity have been reported, the interactions between macronutrient distribution and circadian genes are unclear. The aim of this study was to explore macronutrient intake patterns in the Korean population and associations between the patterns and circadian gene variants and obesity. After applying the criteria, 5343 subjects (51.6% male, mean age 49.4 ± 7.3 years) from the Korean Genome and Epidemiology Study data and nine variants in seven circadian genes were analyzed. We defined macronutrient intake patterns by tertiles of the fat to carbohydrate ratio (FC). The very low FC (VLFC) was associated with a higher risk of obesity than the optimal FC (OFC). After stratification by the genotypes of nine variants, the obesity risk according to the patterns differed by the variants. In the female VLFC, the major homozygous allele of CLOCK rs11932595 and CRY1 rs3741892 had a higher abdominal obesity risk than those in the OFC. The GG genotype of PER2 rs2304672 in the VLFC showed greater risks for obesity and abdominal obesity. In conclusion, these findings suggest that macronutrient intake patterns were associated with obesity susceptibility, and the associations were different depending on the circadian clock genotypes of the CLOCK, PER2, and CRY1 loci.
Effect of Morphological Changes of Maxillary Arch Treated Orthodontically on the Successfulness of Prosthodontic Treatment.

Aims: To evaluate the effects of orthodontic treatment, sex on the maxillary arch measurements, anatomical landmarks position, dimensional differences of artificial teeth selection and position on the comfort for treated partially edentulous patient; with and without previous orthodontic treatment. Materials and Methods: two groups of patients: (Males and females) included in this study. First group were with Orthodontic group classified as: Angle class I malocclusion, crowding more than 5 mm, there were 48 in number. Second group were 32 in number, and they're partially edentulous (with previous orthodontic treatment or without as a control group), they were selected with special criteria. A 192 dental stone casts were prepared, and 64 linear measurements were done for each individual cast of the first group, and 22 measurements for the second group. Crom–Cobalt (Cr–Co.) partial dentures were constructed for the second group individuals, follow up for 3–6 months to detect the comfort of the patient in relation to mean differences in the length measurements of the saddle area were recorded. Results: Incisal canine dimension showed a marked expansion of right side (0.7342 mm) post orthodontic treatment, constriction in the upper inter 1 st molar distance 2.7334 mm in relation to control. Anatomical landmark (canine to hamular notch right and left post orthodontic treatment), in female showed an increase in measurements in relation to male. Length difference of free end saddle area of partially edentulous control group in relation to partially edentulous patient with orthodontic treatment was about 2.987 mm. An increase in percentage of comfort of control patients wearing removable prosthesis was shown in female. Conclusions: Mean values of the all measurements were generally higher in the males than females post orthodontic treatment. Increase in the arc measurements, but with constructions in the inter–molar distance, anatomical landmark labial surface of the central incisors to the incisive papilla, and canine to hamular notch for both groups. Length of artificial teeth of free end partially edentulous with orthodontic treatment was reduced, but the comfort after prosthodontic treatment was higher in female of both groups.
Self-Medication Practice with Antibiotics and Its Associated Factors Among Community of Bule-Hora Town, South West Ethiopia

Background Self-medication with antibiotics is being practiced worldwide with high prevalence, mostly in developing countries. Several factors induce the practice of self-medication, such as irrational and uncontrolled dispensing of medicinal substances, difficulty accessing health-care systems, and cost of diagnosis. Thus, this study assessed the prevalence of self-medication with antibiotics, and its associated factors among the community of Bule-Hora town, South West Ethiopia. Methods A community-based cross-sectional study design was used. All households residing in Bule Hora town were used as source population and households in the selected kebeles were included by using a systematic random sampling method. Eight hundred twenty-six study participants were selected for the study. Pre-tested structured questionnaires had been used to collect the required data. Then the collected data were checked for completeness and analyzed by using SPSS version 20. Odds ratios with 95% C.I. were used to measure the association between independent variables and outcome and variables with p-value <0.05 had been considered statistically significant. Results Prevalence of self-medication with antibiotics in the past 12 months prior to the data collection was found to be 38.9% [95% CI (1.56, 1.64)]. Being male (AOR = 1.53; 95% CI: 0.489, 0.869) with p value of 0.004, no health insurance scheme (AOR = 2.16; 95% CI: 0.274, 0.779) and availability of some drugs in shop (AOR = 12.98; 95% CI: 0.017, 0.353) with p value of 0.001 were found to be significantly associated with self-medication of antibiotics. Conclusion The study revealed that more than one-third of the respondents practiced self-medication. Availability and irrational dispensing of some drugs in the shops were significantly associated with self-medication practice. Therefore, it is important to educate society on the appropriate use of drugs and discourage the use of prescription drugs without medication order.
