In Vietnam, the desire to consume organic vegetables is increasing as people become increasingly concerned about foods that contain several chemicals and toxins that are hazardous to their health. However, numerous subjective and objective factors continue to influence customers' purchase intention and behavior, indicating that this market has not yet reached its full potential. The study analyzes the impacts of trust, price, and convenience on consumers' consumption behavior and frequency of using organic vegetables in Northern Vietnam. We surveyed 312 consumers in the region. After classifying the data, 178 participants have used or regularly used organic vegetables selected for further study. Next, the author applied SmartPLS software with version 3.3 to test the hypotheses and analyze the effects of the observations. The result shows that three main factors affect customers' organic vegetable consumption behavior, especially perceived convenience. This study contributes to the development of comprehensive policy mechanisms and regulations on product traceability. Furthermore, market management authorities must have a strategy in place to inspect the product quality of organic vegetable store chains regularly to build customer trust and support the growth of organic vegetable production and supply chains in Vietnam's northern region.

The purpose of the present study was to present evidence for driving interventions for the elderly by conducting programs that can improve visual perception and cognitive function in a driving simulator for elderly drivers and analyse their effects. Three elderly subjects who were 65 years or older, did not have physical and cognitive impairments, and were able to drive themselves participated in the present study. A total of 12 intervention sessions, of which subjects participated in 10 sessions of nine different visual perception and cognitive function programs available in a driving simulator, were conducted and pre- and post-program assessments were conducted (two assessments in total). The assessments included the evaluation of visual perception, frontal lobe function, concentration, safe driving behaviour, and self-efficacy. The results showed positive effects of the driving simulator program on the visual perception, frontal lobe function, concentration, safe driving behaviour, and self-efficacy of all subjects. Changes in the simulator results showed remarkable improvement in the response evaluation, judgment evaluation, and predictive power evaluation, but showed difficulties in interference tasks and depth perception in common. The results showed positive effects of driving simulator training on the driving ability of the elderly, and consistent provision of such training is expected to improve the quality of life of the elderly by securing the safety of driving and actively supporting social participation.

It is known that the transportation stress of market pigs can affect their carcass quality and that blood concentrations of glucose, creatine kinase (CK) and lactate dehydrogenase (LDH) are indicators of the transportation stress. Fifty-seven gilts and 57 barrows weighing approximately 110 kg were randomly assigned into six groups in a 3 [high (0.31 $m^2/100$ kg BW)-, medium (0.35 $m^2$)- and low (0.39 $m^2$)-stocking densities]${\times}2$[1 h vs. 3 h transportation time] arrangement of treatments. Blood samples were taken during transportation and after 2 h lairage. The percentage of "standing" animals during transportation was less in the low- than in the mediumor high-stocking density; the opposite was true for the "sitting" posture. Plasma concentrations of glucose, CK and LDH increased after loading and declined to the resting levels after lairage. Concentrations of CK and LDH were greater in the 3 h vs. 1 h transportation group. Moreover, the LDH concentration was less in the low- than in the medium- or high-density group. Also detected was a significant interaction between the stocking density and transportation time in all of these blood variables. The incidence of pale, soft and exudative (PSE) carcass was greatest in the high-stocking density group. Interestingly, the PSE incidence increased following the 3 h vs. 1 h transportation at the low-density, but not at the medium-density. Results suggest that the medium-density may be preferable to the lowdensity in the long-distance transportation.

This study is to develop an operating model of Conspectus for online resources by using mechanistic quality factor. Based on some empirical statistics about resource use behaviour such as collection rate, use rate, search rate, the mechanistic quality factor was calculated and applied to each subject by adjusting its acquisition level of Conspectus. according to the result of this study, Acqusition levels of the subject such as technical science which shows higher in use rate, and those such as history and social science which show higher in search rate, should be adjusted to a higher acquisition level, and those of others to the same or a lower level.

This paper reports the syntactic distribution of amu-N-to/-ilato/-ina phrase, which are representative polarity sensitive items. (PSIs) in Korean, and ac- counts for their semantic characteristics in therms of "arbitrary choice quantification" and "concession" In the first section, we extensively illustrate the distributional behaviour of the PSIs in various costructions and roughly generalize the distribu- tion in terms of "(anti/non-) verdicality" Section 2 claims amu denotes an arbi- trary choice quantifier and the particles -to/-ilato/-ina as "concessive" markers, so the compounds denote a special element in a pragmatic scale determined by con- text/situation, Section 3. based on the pragmatics of scalar implicature, accounts for the apparent ambiguity of PSIs between "universal"and "existential"readings and further characterizes the difference among the concessive markers -to/-ilato/-ina in terms of "quantity/ quality scale."rkers -to/-ilato/-ina in terms of "quantity/ quality scale."

Printing ink is faced various shear stress situation until it transfer to the printed substrate through the press. And in each shear stress condition the ink is needed to keep the appropriate viscosity according to the condition. The change of printing ink viscosity has been explained by well-known through the viscosity profile curve. But actually, the quality of printed paper depends on the ink behavior after transfer the substrates. Like this, to look into the behaviour of the ink on the printed substrate, it is needed the experiment of the ink structure recovering by rheology study. In this study, by controling the $CaCO_3$ content in the ink, after investigating the effect of the ink's structure recovery of the pigment concentration, we intend to predict the printing quality of the ink behvior on the substrate depending on pigment content.

The most successful companies today are said to have strong brands. But what is a strong brand\ulcorner What makes a brand strong\ulcorner How do we build a strong brand\ulcorner This paper develops a customer-based brand equity model to help address these important questions. The developed model is a cause-and-effect model linking customer-brand relationships to rational and emotional brand associations, as well as rational and emotional brand evaluations. The customer-brand relationships are characterized by loyalty, based on both behaviour and attitude. As branding is a very complex concept, it is important to determine which of the many branding elements should be included in the model. This paper discusses why a given aspect is important for a brand's equity and which relations exist between the included variables from a theoretical perspective. The model provides insight into the creation of a brand's equity and can thus be used in the brand management process to achieve brand excellence.

During incubation, pelagic seabirds undergo large variations in their body mass as a result of concomitant fasting. In Procellariifomes undergoing important changes in body mass through the incubation, body mass regulation could be an important factor in behavioural decisions for changing activities during the incubation. The aim of this study was to investigate the effect of individuals' quality and incubation behaviour on their body mass regulation in Streaked Shearwaters Calonectris leucomelas breeding at Sasudo Island, in Jeju, South Korea during incubation period, June to August in 2013. In our results, we found that there was no relationship between the daily body mass loss and body size or condition of Streaked Shearwaters. However, the daily body mass loss increased significantly as the incubation bout increased. Moreover, the daily incubation bout was positively related to their body size. Consequently, although breeders' qualities were not related to their daily body mass loss during the incubation, the incubation behaviour affecting their daily body mass loss was regulated by their body size. Therefore, the body size of Streaked Shearwater breeders is one of important factors in their decisions for the incubation behaviour.

Nitrogen is an element required to meet optimal plant growth. However, when it was applied (as chemical fertilizer or animal waste) more than the demand of plant and managed it unreasonably can be accumulated in subsoil and leached from soil system. Nitrogen also can be act as an pollutant to soil and water through water contamination if its concentration exceed the critical level. The concentration and downward movement of nitrate in soil is influenced by cultural practices and soil properties. High level of nitrate nitrogen in drinking water is harzadrous for animal and human health, especially for infants and the restoration of the quality of groundwater is impossible by now. Therefore it is the only way to prevent from leaching of nitrate nitrogen to keep the quality of groundwater as vital water resource. The aims of the presentation of this review paper are to understand the relationship between agricultural practices and the concentration of nitrate nitrogen in groundwater and to suggest further informations for the rational management methods to reduce the leaching of nitrate nitrogen in soil.
