Hotel consumers tend to rely on online reviews to reduce the risk to hotel products when they book hotel rooms because hotel products are high-risk products due to their intangibility. However, the development of ICT has caused information load, and it is an important issue to be perceived as useful information to consumer because a large amount of information complicates the decision making process of consumers. Drawn from Heuristic-Systematic Model(HSM), the present study explored the role of heuristic and systematic cues composing an online review influencing consumers' perception of hotel online reviews. More specifically, this study identified reviewers' identity, level of the reviewer, review star ratings, and attached hotel photo as heuristic cue, while review length, cognitive level of review and negativity in review as systematic cues. The binary logistic regression was adopted for analysis. This study found that only systematic cues of online review were found to affect the usefulness of it. Moreover, we preceded further study examining the moderating effect of seasonality in the relationships between systematic cues and usefulness.

Recently, the korean statistical information service reported that the elder people aged over 65 years take 11 percentage point of all population, indicating that the hyper-elder era will advent shortly. As a result, there are remarkably increasing demands for providing self-organizable home agent system for elder people. Of the home agent system, the ubiquitous home service is known to be useful to overcome this problem. However, current ubiquitous home services limited to provide functional services, and it can be observed that there is lack of consideration for elder-support products which are closely interacted with elder people in the living situation. In this paper, we analyze senior aids products that can be combined to the ubiquitous home service, and propose design procedure for senior aids products that can be applied to self-organizable ubiquitous services. We studied characteristics of elder people, current state of affairs for senior aids products, and home services that are highly required by elder people. Moreover, we observed that the ubiquitous home services related to health, safety, and amenity are urgently needed, and those services can be categorized according to residential areas. Following those observances, we proposed a design principle based on the universal design paradigm to provide self-organizable ubiquitous home service environment for elder people using senior aids products.

Although drugs such as barbiturates and benzodiazepines are often used for the treatment of insomnia, they are associated with various side effects such as habituations, tolerance and addiction. Alternatively, natural products with minimal unwanted effects have been preferred for the treatment of acute and/or mild insomnia, with additional benefits of overall health-promotion. Basic and clinical researches on the mechanisms of action of natural products have been carried out so far in insomnia treatments. Recent studies have been focusing on diverse chemical components available in natural products, with an interest of developing drugs that can improve sleep duration and quality. In the last 15 years, our co-workers have been actively looking for candidate substances from natural products that can relieve insomnia. This review is, therefore, intended to bring pharmacological data regarding to the effects of natural products on sleep duration and quality, mainly through the activation of $GABA_A$ receptors. It is imperative that phytochemicals will provide useful information during electroencephalography (EEG) analysis and serve as an alternative medications for insomnia patients who are reluctant to use conventional drugs.

The authentication and implications of misleading labeling in milk and dairy products is important to protect against cheating consumers from adulteration and to alert sensitive consumers to any undeclared potential allergens. This need to support milk and dairy products labeling has led to the development of specific analytical techniques for the analysis of milk and dairy products ingredients. Recently, several methods based on polymerase chain reaction (PCR), including restriction fragment length polymorphism (PCR-RFLP), multiplex PCR, species-specific PCR, and real-time PCR, have been proposed as useful means for identifying species of origin in milk and dairy products, as well as quantifying and detecting any adulteration. These methods have particular advantages owing to their high specificity and sensitivity, as well as rapid processing time. In this review, we provide an updated and extensive overview of the PCR-based methods used for milk and dairy products authentication with a particular focus on the application of PCR methods to detect adulteration.

This study investigated the current processing degree and ingredients of sauce on the packaging of the commercial eel products made in Northeast Asia (Korea, Japan, China and Taiwan) and surveyedthe perception of nutritional functionality and purchasing pattern of Japanese consumers for the processed eels. The results are considered as a useful aid for preparation of processed eel products. The commercial eel products, purchased at a department store, supermarket and discount market, were divided by processing method, package quantity, storage method and sauce ingredients. The processing method was indicated in many different ways in each country, such as sauce ingredients and intake method. A questionnaire survey was conducted on 105 Japanese consumers (male 43, female 62) visiting Korea. Of the respondents, 44% answered and the major reasons for purchasing processed eel products were as a side dish for meals. The results for this factor were significantly different in relation to age (p <0.05). The degree of perceptions of functional excellence about processed eel products was well known (37%), some (49%), and seldom (14%). The results for this factor were significantly different in relation to age (p <0.001). Seventy-five percent of the respondents had experienced processed eel products. The type of purchase of the respondents was highest for vinegared rice and fish (47%), followed by freezing (33%), canning (5%), and dried food (4%), in that order.

This study intended to determine how price-ending types used for menu products affected consumers' price evaluation and value perception and such behavioral intentions as purchase intention and search intention. The collected data went through statistical processing, including frequency analysis, factor analysis, T-test and ANOVA using an $SPSS/PC^+$ 12.0 statistical package. The results can be summarized as follows: First, as for differences in internal reference price by ending, internal reference price was lower if menu ending was an odd number than it was an even number, which indicates that consumers tend to consider the price of the menu products to be lower if the ending of menu products is an odd number. Second, menu price-ending was found to have significant differences on consumers' purchase intention, search intention, and value perception. But the results of two-way ANOVA showed that price ending by restaurant types had no effect on consumers' search intention and restaurant type. This study suggested a desirable external reference price-ending type for menu products as one of sales promotion strategies to menu products planners and drew up a concrete plan to determine which price-ending type is useful by consumers' personal properties.

The purpose of this study was to explore the influencing factors of consumption behavior of healthy functional foods including vitamin/mineral products for overweight and obese Koreans. Overweight and obese Koreans were selected based on the body mass index(BMI) from the KNHANES that was collected in 2007. Probit estimation model was used to find the influencing factors such as age, gender, job, education, income, nutrition education, and cultural capital(parents' education) on consuming the healthy functional foods. Overweight consumers were found to consume vitamin/mineral products and healthy functional foods at 17.5% and 22.7%, respectively. Obese consumers were found to consume vitamin/mineral products and healthy functional foods at 18.2% and 22.8%, respectively. In addition, self decision was found to be a significant factor to consume both products in both groups. Nutritional education and job were significant factors to consume vitamin/mineral products in overweight consumers, while mother's education and job(service) were significant factors in obese consumers. Weight control for body shape, gender, age, and income were significant factors to consume healthy functional foods in overweight consumers, while nutrition label and perceived health status were significant for obese consumers. Therefore, providing consumer information on functional foods might be useful for consumers to consider the healthy functional foods as an available option to purchase. Various influencing factors between two groups might be concerned to develop different strategies for promoting the healthy functional foods consumption including vitamin/mineral products.

Purpose: Islamic banking products and services have always claimed to be unique from its traditional interest-based counterpart. However, in practice, many Islamic banks are alleged to have drifted away from its paradigm version. The purpose of this study is to gauge the perception of university students in Malaysia towards Islamic banking products. Research design, data and methodology: Data were collected from 250 Malaysian university students. Structural Equation Modeling (SEM) was performed to test proposed hypotheses to identify factors influencing customers' perception toward Islamic banking products. Results: The main finding indicates that most of the respondents are familiar with Islamic banking products and consider Islamic banking products as useful as its conventional counterparts. The regression results show that respondents are less convinced of adherence to Shari'ah, efficiency and helpfulness of existing Islamic banks. Conclusions: This is a cue to the Islamic banks' stakeholders that they need to realign their practices in an ethically responsible way in accordance with Shari'ah if they wish to secure existing customers and attract potential ones. In a competitive banking environment, most banks provide efficient and readily available service; thus, focusing on this as a strategy hardly distinguishes an Islamic bank from an interest-based bank.
