This article investigates perceptions and use of Open Access journals (OAJs) by master's degree students in two universities in the southwestern part of Nigeria. A descriptive survey design was used in the study and the study population was comprised of 7,423 master's degree students in the University of Ibadan and 1,867 from Obafemi Awolowo University. A multistage random sampling technique was used to select a sample size of 249 and the data collection instrument was a structured questionnaire. Data were analyzed using frequency counts, percentages, mean, standard deviation, correlation, and regression analyses. The findings revealed that OAJs were used for learning, dissertation writing, personal research, and development. OAJs were not frequently used because of download delays, unavailability of Internet facilities, and limited access to computers terminals, among other issues. OAJs were found to be of relative advantage, positively perceived, and found to be compatible with existing values and quality assurance in scholarly publications, hence their use for academic activities. The regression analyses showed that there was a significant positive relationship between positive perception, perception of relative advantage, perception of compatibility, perception complexity, and master's degree students' use of OAJs. Negative perception was found to have a significant negative correlation with the use of OAJs. This article recommends that quality assurance of OAJs should be ensured in order to boost users' positive perceptions to increase their patronage and usage of these scholarly outlets for various academic activities, which will in turn encourage research and development across the various institutions of higher learning in Nigeria.

As students can purchase textbooks online or from local bookstores, we proposed a model to study the predictors of textbook purchasing from online bookstores based on the theory of reasoned action (TRA) and technology acceptance model (TAM). The survey instrument consisted of 51 items to assess 10 constructs of the proposed model, where the items used to measure the constructs were adapted from previous literature. Pre-testing and pilot testing of the measures were conducted by selected users of online bookstores. Data were collected from 220 university students who have purchased and intend to purchase their textbooks from online bookstores. The findings of this research are summarized as follows. First, navigation, previous experience, and innovation have a significant impact on the buyer's perception of ease of use. Second, price and delivery services have a significant impact on the buyer's perception of usefulness. Third, the perception of ease of use also has a significant impact on the buyer's perception of usefulness. Fourth, the perception of ease of use, perception of usefulness, and subjective norms all significantly support the purchasing intention in the case of online bookstores.

The purposes of this study were to define housewife's risk perception and risk reduction behavior when purchasing children's wear, and to identify the differences according to the clothing buying behavior and demographic characteristics. Data were gathered through survey with 429 housewives in Seoul and metropolitan area, and then statistically analyzed by descriptive statistics, factor analysis, Analysis of Variance (ANOVA), Duncan's test, and Pearson's correlation analysis. The results showed partially significant differences in risk perception, especially economic risk and social psychological risks, among housewife consumer groups according to the clothing buying behavior and the demographic characteristics. There were significant differences in risk reduction behaviors among the groups, especially brand preference/industry information, observation/experience, and media information. Also, correlations between risk perception and risk reduction behaviors were found. The social psychological risk perception was highly correlated to the risk reduction behaviors, while the time/convenience loss risk was not correlated to any risk reduction behavior. The results of this study provide insight into children's wear business through suggesting marketing implication.

This study is to estimate differences, relationships and related factors of environmental risk perception and perceived benefit among residents and workers. A self-administered questionnaire survey using a structured instrument was carried out to residents and workers in industrial area during April, 2002. Total number of participants were 657 including 329 residents and 328 workers. Participants assessed environmental risk perception, self- assessed knowledge, trust in authorities and perceived benefit associated with 10 products manufactured in industrial area. There were difference in environmental risk perception, knowledge and trust in authorities and perceived benefit among residents and workers. Especially, trust in authorities and perceived benefit were statistically significant difference among residents and workers. Inverse relationships between environmental risk perception and perceived benefit have been observed for different products. In other words, the greater the perceived benefit, the lower the perceived risk, and vice versa. Factors mostly associated with participant's characteristics of environmental risk perception were age. marriage status (workers), education level (workers). There was statistically significant difference. Perceived benefit was statistically significant difference with sex, marriage status, residence duration, education level (workers). Related factors of environmental risk perception among residents and workers were age, trust in authorities. And factors affecting the perceived benefit were sex, age, education level (workers), and trust in authorities (workers). According to the results, people having high trust in the authorities perceived less risks than people having low in the authorities. To improve the communication of risk information, further study focus on assessment of experts, government and stakeholder in industrial area. Methodologies of this study can be used as the basis for investigating the structure of public perception of environmental products risks and benefit, designing a public information and risk communication program, and developing policy actions to improve acceptance.

This paper presents an image processing method which emphasizes a certain perception feeling on a color image. A series of fuzzy image processing schemes are proposed, which transform an color image represented in the LCH coordinate system to the image with a certain perception feeling based on the rules and fuzzy inference. To obtain the rules, results of the sensory perception tests are applied to the quantification theory. The proposed schemes can be effectively utilized in the color copy system, since printed outputs possibly look better than originals.
