This study will specifically tackle the ongoing vaccination efforts against the Covid-19 pandemic. The aim is to identify and measure the posited influencing factors that could affect the attitude and intention towards the Covid-19 vaccination programs. This study utilized and expanded the Technology Acceptance Model (TAM), incorporating the Protection Motivation Theory (PMT), and Theory of Planned Behavior (TPB) to research and find out the prospective antecedents of vaccination programs. An online survey was conducted and the participants were asked questions regarding constructs such as Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, and Threat Appraisals. The examined target data sets were from 243 respondents who are Filipino citizens. Structural Equation Modeling (SEM) techniques were used to prove the fit of the hypotheses. The results show that the model is supported partially because factors like Effort Expectancy, Facilitating Conditions, and Threat Appraisals did not show any significant effect on Attitude and Intention. However, certain aspects such as Social Influence and Performance Expectancy did indeed have a significant relationship that affects Attitude and in turn have a significant relationship toward Vaccination Intention. Lastly, the empirical results of this study can hopefully provide some reference in improving the implementation of future vaccination programs. Although not all of the factors that were measured in this study proved to be significant, it can serve as a basis to provide a more comprehensive understanding of the influencing factors on vaccinations. It can also aid local governments and medical institutions to manage, execute, and evaluate measures against the pandemic and find ways and strategies to promote vaccination programs to different demographics. The Covid-19 pandemic has affected the whole world regardless of nationality, race, and socio-economic background. Finding ways to improve the perceived usefulness, systems, and policies of these vaccination programs could significantly increase the attitude and behavior intention toward the Covid-19 Vaccine

Slaked lime is commonly used as alkali agent for dry scrubbing of hydrogen chloride and sulfur oxides in flue gas discharged from municipal solid waste incinerators (MSWIs). As the utilization amount of slake lime is the most among chemicals used in MSWI, its impact on the operating cost is significant. For this reason, the on-site production of slaked lime was attempted by using cheap quicklime and a simplified hydrator in MSWI. However, the discharge problem of fly ash occurred at the hopper of bag filter (BF) owing to the poor flow property of on-site produced slaked lime when it was tested in the demonstration facility. In this study, we developed lab-scale of flowability tests to evaluate the flow property of produced slaked lime as well as to find the optimum condition of on-site production. First, three kinds of flowability tests were examined to understand the behavior of slaked lime in hopper. Procedure and details of each test method were determined using reference samples: one is commercial slaked lime (MS) which did not occur bridging problems in the demonstration test. The other is on-site produced slaked lime (TR) which occurred bridging problem in the same test. Details of each test were determined as follows: 1) slide test at slope: a specimen with a fixed volume (9 ㎠×6mm) was placed on SUS plate and the inclination of SUS plate was increased. The angle of slide, θ [°] that the specimen was falling from SUS plate was determined; 2) Stirring torque test: 2.5 kg of sample was filled in a stainless container. While the blades attached to the motor were stirred at 1 rpm, the resistance generated was measured as torque, T [Nㆍm]; 3) orifice outflow test: a 400 g of sample in a SUS hopper was discharged through an orifice with diameter 24 to 60 mm. From the relationship between orifice diameter and outflow rate, OD₅₀ [mm] that 50% mass of slake lime was discharged (OD₅₀) was determined. Various kinds of on-site produced slaked limes were prepared to understand the relationship between flowability and production conditions. Molar ratio of distilled water to quicklime (WR), residence time in hydrator, stirring rate, addition of chemical, pulverization strength, etc. were tested as production conditions. Fig. 1 shows that the angle of slide increases as the moisture content of on-site slaked lime increases. As the fraction of particle size less than 5μm increases, both torque and OD₅₀ increase (Figs. 2 and 3). It was found that the flow property of slaked lime could be improved by reducing the moisture content and the fraction of particle size less than 5μm.

Little information is available on vegetative and generative performance of apple cultivars during the early growth of trees in orchards. The aim of this five-year study was to evaluate 2 vegetative (trunk cross sectional area (TCSA) and tree height (TH)) and 7 generative parameters (tree yield (TY), fruit number per tree (FNT), crop load (CL), fruit diameter (FD), shape index (SI), fruit surface color (FSC) and fruit color intensity (FCI)) and their inter-correlations (Pearson correlation, regression analyses and PCA) for young apple trees, on 9 apple cultivars (‘Jugala’, ‘Galaval’, ‘Gala Venus Fengal’, ‘Gala Decarli-Fendeca’, ‘Gala Schnitzer (S) Schniga’, ‘Fuji September Wonder’, ‘Crimson Crisp (Co-op 39)’, ‘Jeromine’, and ‘Red Idared’) in a slender spindle training system (2597 trees ha−1) and on 4 apple cultivars (‘Wilton’s Red Jonaprince’, ‘Red Cap Valtod (S)’, ‘Early Red One’, and ‘Red Topaz’) in a super spindle training system (5194 trees ha−1) in Eastern Hungary. The strongest vegetative growth was observed in ‘Red Idared’, while the weakest was in ‘Early Red One’. Most ‘Gala’ mutants showed high yields in all years, except for ‘Galaval’. On the 6 year-old trees, the lowest tree yield was found in ‘Fuji September Wonder’ (8.2 kg tree−1), while the highest was found in ‘Gala Venus Fengal’ (35.8 kg tree−1). The lowest fruit number per tree (15 fruit tree−1) was found in ‘Jeromine’, while the highest (222 fruit tree−1) was in ‘Gala Venus Fengal’. The highest crop load was found in ‘Gala Venus Fengal’ (12.72 fruit per cm2 TCSA), while the lowest was in ‘Jeromine’ (2.13 fruit per cm2 TCSA). The smallest fruit diameter (66.3 mm) was recorded in ‘Gala Schnitzer (S) Schniga’, while highest (93.6 mm) was in ‘Red Idared’. The lowest shape index (0.73) was found in ‘Red Topaz’, while the highest (0.92) was in ‘Red Idared’. The majority of the cultivars reached very good fruit surface color (80–100%). The lowest fruit surface color (40%) was observed in ‘Gala Schnitzer (S) Schniga’, while the highest (100%) was in ‘Jeromine’ and ‘Early Red One’. The highest fruit color intensity was observed in most cultivars with the exception of ‘Jeromine’, ‘Gala Schnitzer (S) Schniga’ and’Fuji September Wonder’. In addition, correlation and regression analyses revealed strong and significant (p = 0.05) relationships between TH vs TCSA, TY vs TCSA, TH vs TY, TY vs FNT, and FCI vs FSC. PCA explained 87% of the total variance and PC1, PC2, PC3, and PC4 accounted for 33, 21, 20, and 13% of the variance, respectively, and correlated with TSCA, TH, TY and FNT; with FNT, CL and FS; with FSC and FCI; and with TH and SI, respectively. In conclusion, our study provides useful tree property data on prospective mutants/cultivars for growers/advisors in order to select the most suitable cultivars for establishing new orchards under climate conditions similar to central Europe.

Pitch Measurement of 150 nm ID-grating Standards Using an Nanometrological Atomic Force Microscope

진종한,Ichiko Misumi,Satoshi Gonda,Tomizo Kurosawa 한국정밀공학회 2004 International Journal of Precision Engineering and Vol.5 No.3

Pitch measurements of 150 nm one-dimensional grating standards were carried out using a contact mode atomic force microscopy with a high resolution three-axis laser interferometer. This measurement technique was named as the nano-metrological AFM. In the nano-metrological AFM, three laser interferometers were aligned precisely to the end of an AFM tip. Laser sources of the three-axis laser interferometer in the nano-metrological AFM were calibrated with an I2-stabilized He-Ne laser at a wavelength of 633 nm. Therefore, the Abbe error was minimized and the result of the pitch measurement using the nano-metrological AFM could be used to directly measure the length standard. The uncertainty in the pitch measurement was estimated in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM). The primary source of uncertainty in the pitch-measurements was derived from the repeatability of the pitch-measurements, and its value was about 0.186 nm. The average pitch value was 146.65 nm and the combined standard uncertainty was less than 0.262 nm. It is suggested that the metrological AFM is a useful tool for the nano-metrological standard calibration.
