The purpose of the study is to investigate the simulated effects of the Philippine tax reform, which is called Tax Reform for Acceleration and Inclusion Law, on household income and occupational choice. The study utilized the Family Income Expenditure Survey and tax collection as input to Computable General Equilibrium-Top Down Behavioral Microsimulation approach to determine the effect of Philippine tax reform on household income and occupational choice. The results of the study show that the household income in the Philippines will increase due to the implementation of the Philippine tax reform. Also, the study had found that tax reform results drive the household to shift from being farming entrepreneur to salaried workers since the utility derived from being workers is much higher compared to the utility derived from being entrepreneur. The findings of this research suggest that the Philippine Tax Reform for Acceleration and Inclusion Law is beneficial to the household since their income would increase, which will further result to an increase in their capability to buy goods and services. However, the tax reform would also lead to imbalance between the distribution of numbers of workers across sectors such as entrepreneurial farming, entrepreneurial non-farming, and wage sector.

Nowadays, organizations have adopted Smart Work to efficiently manage tasks, such as electronic document approval, customer management, and site inspection, without spatial-temporal constraints. Smartphones, which are commonly used in Smart Work, enable individuals to perform their jobs anytime and anywhere, thus blurring the boundary between work and non-work. To solve the problem of blurred work/non-work boundaries, a construct of self-control and affective factors needs to be considered because business style is changed from command to autonomy in the Smart Work context. Moreover, employees can convey their emotions easily over smartphones. Recent marketing studies have analyzed consumers' behavior based on the combination of cognitive, affective, and behavioral components, and researchers of information systems are also interested in these factors. However, previous research has some limitations, such as not classifying factors into cognitive, affective, and behavioral as well as not covering all three factors. Therefore, we explore the roles of cognitive, affective, and behavioral components in emotional exhaustion and education performance, and conduct a survey on undergraduate and graduate students, who are the major users of smartphones. Findings show that when individuals improve their cognitive capability (self-control) and usage experience (smartphone communication and internet usage), they can decrease emotional exhaustion and increase education performance. In the role of affective capability, increasing education performance is partially accepted. These results imply that organizations should not focus on controlling the usage of smartphones but on promoting appropriate smartphone usage.

Objectives: This study was performed to evaluate the consumer education program for reducing sodium intake based on social cognitive theory (SCT) and investigate consumer perceptions of environmental, cognitive and behavioral factors. Methods: Consumers (n=4,439) were recruited nationwide in Korea to participate in a nutrition education program for reducing sodium intake which was targeted on senior housewives (SH), parents (P), and office workers (OW). Questions regarding main factors of SCT were asked both before and after the education program. Results: SH and P recognized external social efforts and information to reduce sodium including nutrition labeling more than OW. The main barriers to practice reducing sodium intake were limited choice of low sodium food and menu, interference with social relationship when dining with others, and limited information, knowledge and skills. SH had lower barriers to practice reducing sodium intake and OW perceived 'preference to soup or stew' and 'preference to Kimchi, salted fish and fermented sauces' as barriers more than other groups at the baseline. Less than 50% of participants knew the relationship between sodium and salt, sodium in nutrition labeling, and recommended sodium intake. In addition, OW had little knowledge for capability to reduce sodium intake and lower self-efficacy to practice compared with SH and P. After education, positive outcome expectations such as lowering blood pressure, prevention of cardiovascular disease and osteoporosis were increased and barriers to practice reducing sodium intake were decreased in all groups (p < 0.05). The knowledge for behavioral capability and self-efficacy to reduce sodium intake were also improved but OW had still lower scores compared with other groups. Conclusions: These results suggested that nutrition education programs could be an effective tool to impact general population by facilitating awareness and increased capability to reduce sodium intake.

This study aimed to figure out the factors affecting the self-esteem of children. For this purpose, 296 fosterers (those who use the children education institutions) were targeted to analyze the factors affecting the self-esteem of children. The factors can be categorized as the personal internal factors (problematic behavior and self-control capability of the children) and the environmental factors (parenting efficacy and parenting stress of the fosterers). As a result, self-assessment, depression, emotionality, and behavioral restriction factors of the children and child-rearing efficacy, and the child-rearing stress of the fosterers were proven to be influential; these two factors have 50.5% of the explanation power. In conclusion, if self-assessment, emotionality, and behavioral control of the children and rearing efficacy of the fosterers were high, self-esteem of the children was increased. However, if depression of the children and rearing stress of the fosterers were high, self-esteem of the children was decreased. This result suggests a need of program development and a new teaching method to reduce problematic behavior of the children and rearing stress of the fosterers, as well as to enhance rearing efficacy of the fosterers and self-control capability of the children for the purpose to increase self-esteem of the children.

Evaluating ubiquitous computing services is important for the commercialization of the ubiquitous services which will be running on electronic markets. However, despite its importance and usefulness, assessing ubiquitous computing services is still in its early stage. Moreover, sufficient study of making a distinction what are 'ubiquitous computing services' or not has not been provided yet. Hence, this paper aims to propose an integrated methodology to assess the ubiquitous computing services. A multilayered approach is considered to assess not only technical but also behavioral perspectives. To show the feasibility of the assessment model, three use cases are studied and evaluated.

The purpose of this study was to look into the service quality of websites and the attributes of review information thereon as perceived by visitors thereto and to analyze the effect that the service quality of festival websites and informative usefulness of testimonials would have on the satisfaction with use, along with the effect that the satisfaction with use would have on behavioral intention. Based on the results of this study, we intended to present measures that could help strengthen the intention to spread positive word-of-mouth for festivals and to visit a festival through satisfaction with a festival's website. The festival selected to achieve the objectives of this study was the Yeongdeok Snow Crab Festival, which is one of the most renowned local food festivals in the Gyeongbuk region, having been held for 17 consecutive years, and has been selected as the top festival of Gyeongsangbuk-do for 4 consecutive years. We surveyed visitors to Yeongdeok Snow Crab Festival who had searched for information on the Yeongdeok Snow Crab Festival prior to its opening, as well as those who had participated in Yeongdeok Snow Crab Festival before. The results of this study showed that review information on a food festival website, service quality design, adequacy of substance, responsiveness to customers, and system capability were found to have a positive effect on behavioral intention through satisfaction with use. The findings suggest that it is crucial to manage the service quality of websites in order to stimulate interest in, and induce visits to, food festivals.

Background: Korean ginseng (Panax ginseng Meyer) contains a variety of ginsenosides that can be metabolized to a biologically active substance, compound K. Previous research showed that compound K could be enriched in the red ginseng extract (RGE) after hydrolysis by pectinase. The current study investigated whether the enzymatically hydrolyzed red ginseng extract (HRGE) containing a notable level of compound K has cognitive improving and neuroprotective effects. Methods: A scopolamine-induced hypomnesic mouse model was subjected to behavioral tasks, such as the Y-maze, passive avoidance, and the Morris water maze tests. After sacrificing the mice, the brains were collected, histologically examined (hematoxylin and eosin staining), and the expressions of antioxidant proteins analyzed by western blot. Results: Behavioral assessment indicated that the oral administration of HRGE at a dosage of 300 mg/kg body weight reversed scopolamine-induced learning and memory deficits. Histological examination demonstrated that the hippocampal damage observed in scopolamine-treated mouse brains was reduced by HRGE administration. In addition, HRGE administration increased the expression of nuclear-factor-E2-related factor 2 and its downstream antioxidant enzymes NAD(P)H:quinone oxidoreductase and heme oxygenase-1 in hippocampal tissue homogenates. An in vitro assay using HT22 mouse hippocampal neuronal cells demonstrated that HRGE treatment attenuated glutamate-induced cytotoxicity by decreasing the intracellular levels of reactive oxygen species. Conclusion: These findings suggest that HRGE administration can effectively alleviate hippocampus-mediated cognitive impairment, possibly through cytoprotective mechanisms, preventing oxidative-stress-induced neuronal cell death via the upregulation of phase 2 antioxidant molecules.
