The present study was designed to investigate the efficacy of selective $ET_A$ receptor antagonist, ambrisentan on hyperhomocysteinemia-induced experimental vascular dementia. L-methionine was administered for 8 weeks to induce hyperhomocysteinemia and associated vascular dementia in male rats. Ambrisentan was administered to L-methionine-treated effect rats for 4 weeks (starting from $5^{th}$ to $8^{th}$ week of L-methionine treatment). On $52^{nd}$ day onward, the animals were exposed to the Morris water maze (MWM) for testing their learning and memory abilities. Vascular endothelial function, serum nitrite/nitrate levels, brain thiobarbituric acid reactive species (TBARS), brain reduced glutathione (GSH) levels, and brain acetylcholinesterase (AChE) activity were also measured. L-methionine-treated animals showed significant learning and memory impairment, endothelial dysfunction, decrease in/serum nitrite/nitrate and brain GSH levels along with an increase in brain TBARS levels and AChE activity. Ambrisentan significantly improved hyperhomocysteinemia-induced impairment of learning, memory, endothelial dysfunction, and changes in various biochemical parameters. These effects were comparable to that of donepezil serving as positive control. It is concluded that ambrisentan, a selective $ET_A$ receptor antagonist may be considered as a potential pharmacological agent for the management of hyperhomocysteinemia-induced vascular dementia.

Purpose: Traditional markets have served as important locations for social-cultural and economic activities. It is a hub of economic transactions and where people gather and exchange information and goods, while also serving as the center of social activities, including commercial exchanges. Accordingly, this study aimed to contribute to the studies on the perceived value in traditional markets for customers in different aspects. Research design, data, and methodology: To analyze the proposed model, data was collected from 456 respondents and analyzed with SPSS 21.0 and AMOS 21.0. The data was analyzed with structural equation modeling (SEM) using path analysis. Results: According to the results of the analysis, the perceived value comprises utilitarian value, emotional value, economic value, and social value, all of which had a positive impact on attitude. Emotional value and social value had a positive impact on subjective norms, while utilitarian value and economic value did not have an impact on subjective norms. Also, attitudes and subjective norms were found to have a positive impact on behavioral intention. Conclusions: Through this study, the value that the traditional markets need to provide to consumers have been identified. Traditional markets should develop into places that can provide value for their consumers.

The transmission opportunities between nodes in Delay Tolerant Network (DTNs) are uncertain, and routing algorithms in DTNs often need nodes serving as relays for others to carry and forward messages. Due to selfishness, nodes may ask the source to pay a certain reward, and the reward may be varying with time. Moreover, the reward that the source obtains from the destination may also be varying with time. For example, the sooner the destination gets the message, the more rewards the source may obtain. The goal of this paper is to explore efficient ways for the source to maximize its total reward in such complex applications when it uses the probabilistic two-hop routing policy. We first propose a theoretical framework, which can be used to evaluate the total reward that the source can obtain. Then based on the model, we prove that the optimal forwarding policy confirms to the threshold form by the Pontryagin's Maximum Principle. Simulations based on both synthetic and real motion traces show the accuracy of our theoretical framework. Furthermore, we demonstrate that the performance of the optimal forwarding policy with threshold form is better through extensive numerical results, which conforms to the result obtained by the Maximum Principle.

In the course of this research, we developed FRIS(Food Replica Information System), which calculates calories and nutrient values of foods in a very simple and interesting manner, and experienced of application to some communities. We expect that individuals will have opportunities to raise their consciousness of food, nutrients, and healthy living by participating in FRIS. 154 kinds of commonly consumed Korean foods were selected and one serving sized food replicas, having the same shapes, size, and color as the real foods, were constructed with attached bar code labels. An application program with food replicas and bar code was also developed in order to provide information on calories and nutrient values for people's meals or selected foods based on survey results of housewives' requirements related to foods and nutrients. FRIS should be a basic tool in nutrition education and consultation. Its applicability would vary according to the nutritionist's flexibility and contents of developed application programs. Technical stability should be strengthened and more useful contents of application prograln be added to spread the use of the system. Additionally, in future research, more delicate models should be developed and an analytical method should be applied to examine the effects of FRIS to individual behavioral changes in their eating habits.

This paper investigates the effect of the involvement of the board chairman in the audit committee (AC) on earnings management (EM). It examines Bursa Malaysia-listed companies with the lowest positive earnings for the years 2013 to 2015. The Modified Jones Model by Kasznik (1999) was used to determine discretionary accruals. An AC that includes its board chairman as an ordinary member is associated with greater discretionary accruals. However, a board chairman who is also the chairman of the AC does not seem to influence discretionary accruals. This paper supports the agency theory and policy-makers' efforts to prevent board chairmen from sitting on ACs. It is the first study that uses the agency theory to describe the association between the board chairman's involvement in the both AC and EM. This study alerts policy-makers, stakeholders and researchers to the influence of a board chairman serving on the AC in curbing EM. Furthermore, it provides empirical evidence that the majority of Malaysian companies whose board chairmen are involved in the AC appoint the chairman as an ordinary member of the AC. This indicates that executive directors may affect such actions. Hence, more policies are needed to improve AC independence.

Piezoelectric and dielectric behaviors of a piezoceramic patch adhesively centered on a carbon composite plate are identified using a robust multi-objective optimization procedure. For this purpose, the patch piezoelectric stress coupling and blocked dielectric constants are automatically evaluated for a wide frequency range and for the different identifiable behaviors. Latters' symmetry conditions are coded in the design plans serving for response surface methodology-based sensitivity analysis and meta-modeling. The identified constants result from the measured and computed open-circuit frequencies deviations minimization by a genetic algorithm that uses meta-model estimated frequencies. Present investigations show that the bonded piezoceramic patch has effective three-dimensional (3D) orthotropic piezoelectric and dielectric behaviors. Besides, the sensitivity analysis indicates that four constants, from eight, dominate the 3D orthotropic behavior, and that the analyses can be reduced to the electromechanically coupled modes only; therefore, in this case, and if only the dominated parameters are optimized while the others keep their nominal values, the resulting piezoelectric and dielectric behaviors are found to be transverse-isotropic. These results can help designing piezoceramics smart composites for various applications like noise, vibration, shape, and health control.

Purpose: This study is to identify the health promoting behaviors, health belief, and self-efficacy of visiting nurses working for the Health Visiting Project in Seoul and to determine the predictors of influencing health promoting behaviors. Methods: Data were collected from an online survey of 496 visiting nurses form 25 districts in Seoul. Using SPSS ver. 24, the study performed descriptive statistics, t-test, one-way ANOVA, correlations, and stepwise multiple regression. Results: The mean scores for health promoting behaviors and self-efficacy were slightly higher than that of the median, whereas health belief showed in the median. The factors influencing health promoting behavior were perceived barriers, perceived sensitivity, self-efficacy, and age. These variables explained 36.0% of health promoting behaviors(F=60.62, p<.05). Conclusion: To prevent illness and to promote the health of the population, the visiting nurse mainly performs health screening, health education and counseling. To fulfill these responsibilities, the visiting nurse should be healthy and perform health promoting behaviors well, effectively serving as a model for their clients. Most of the visiting nurses were middle-aged, thus, it is necessary to strengthen health promotion activities that manage physical and psychological health at the individual level.
