  • The purpose of this study was to compare the effects of two different types of texts, which were narrative and expository, on the understanding of content. Elementary students' perceptions of the two types of the texts were also investigated. In the comparison of the effects on the understanding of the text contents, test scores of mind-mapping, closed-answer question, and essay test were used. The analyses of mind-mapping tests showed narrative text was more effective to figure out main concepts of the text throughout the mind-mapping test. But expository text was more effective in the hierarchical organization of the concepts. In the closed-answer questions and essay test, narrative text was more effective than expository text. However when the contents of text were difficult and complex, there was no meaningful difference between the two types of texts. The analyses of students' perceptions of the texts showed that narrative texts were preferred. Students perceived that the narrative text was more interesting and familiar. However, the perceptions of helpful text for their science learning were not different by the types of texts.

  • The purpose of this study is to examine to what extent the context in which people interact with online information affects people's credibility perceptions. In this study, credibility assessment is defined as perceptions of credibility relying on individuals' expertise and knowledge. Context has been characterized with respect to three aspects: Context as user goals and intentions, context as topicality of information, and context as information activities. The data were collected from two empirical studies. Study 1 was a diary study in which 333 residents in Michigan, U.S.A. submitted 2,471 diary entries to report their trust perceptions associated with ten different user goals and nine different intentions. Study 2 was a lab-based study in which 64 subjects participated in performing four search tasks in two different information activity conditions - information search or content creation. There are three major findings of this study: (1) Score-based trust perceptions provided limited views of people's credibility perceptions because respondents tended to score trust ratings consistently high across various user goals and intentions; (2) The topicality of information mattered more when study subjects assessed the credibility of user generated content (UGC) than with traditional media content (TMC); (3) Subjects of this study exerted more effort into making credibility judgments when they engaged in searching activities than in content creation. These findings indicate that credibility assessment can or should be seen as a process-oriented notion incorporating various information use contexts beyond simple rating-based evaluation. The theoretical contributions for information scientists and practical implications for web designers are also discussed.

  • The purpose of this study was to investigate children's self-perceptions of social competence in three different levels of peer status and to determine the degree of congruence between children's perceptions and teachers' ratings of social competence. The subjects were 46 bpys and 44 girls identified as popular neglected and rejected by peers in preschool and in first and second grades. A sociometric test was used to identify children's peer status. Children's self-perceptions were assessed by the social Competence Scale for Young Children and teachers' assessment of children's competence was collected by a rating scale. The data were analyzed by 3-way ANOVA 2-way MANOVA for repeated measures and pearson product-moment correlations. The results showed that children's self-perceptions of social competence were generally positive and not significantly different by peer status and grade level in three of the four domains. For the maternal acceptance domain the degree of acceptance perceived by neglected group decreased with grade while those of popular children increased. The degree of congruence between children's perceptions and teachers' ratings were different by peer status. Popular children's estimation of their social competence was more congruent with teachers but neglected and rejected children overestimated their competence.

  • Objectives: This research was conducted to recognize dental health care employees' awareness of patient safety culture and to examine the association between awareness of patient safety culture and patient safety activities. Methods: The subject of this research includes the dental health care employees from 11 different dental hospitals in the nation, dental offices in the 6 different general hospitals in Seoul, and 4 different private dental offices in 2014. A self-reported questionnaire was completed by 485 dental health care employees from March 17 to April 3, 2014. Multiple regression models were used in the analysis. Results: First, the dental health employees' awareness of patient safety culture was 3.25 on average. The extent of patient safety activities was 2.75. The behavior of the supervisor/manager and the adequate explanation showed positive correlation with r=0.213 (p<0.001). The process of communication and the preventative inspection of the medical equipment showed negative correlation with r=-0.258 (p<0.001), and especially the awareness of patient safety culture and the infection control exercise showed the most significant correlation (r=0.293, p<0.001). Second, hospital environment factor of patient safety perceptions positively were related to most of patient safety management activities after controlling several covariates. Conclusions: The result of this research showed that most of the patient safety culture perceptions positively were correlated with patient safety activities. We also found that proper hospital environment, simple communication process, and positive perceptions for patient safety level were more likely to perform patient safety management activities after controlling several covariates. Improving the patient safety perceptions of dental hospital workers is an important consideration.

  • This study examines the effects of restaurant attributes on customers' perceptions of price and brand reputation. Four restaurant attributes were used to represent restaurant quality. Multiple regression was conducted to measure the relationships between the four restaurant attributes and price and brand reputation. Further, an independent T-test was used to compare differences between perceptions of locals and tourists with regard to restaurant quality under two categories (price and brand reputation) after they selected a restaurant. Results of this study revealed that residency did not have a significant impact on customers' perceptions of price or brand reputation, whereas restaurant attributes did have an impact. Taste was a predictor of perceived price, whereas service and atmosphere were predictors of brand reputation. In addition, comparison of restaurant attributes between locals and tourists showed that sanitation and service were significantly different in accordance with price and atmosphere, whereas taste and service were significantly different in accordance with brand reputation. Locals showed higher means for each restaurant attribute compared to tourists.

  • This study analyzed the relationships among perceptions of uncertainty, environmental characteristics and strategy maker\`s actual decision such as resource allocation in different organizational subunits by focusing on the hotel general managers in two different countries Korea and Japan. The results show that managerial perceptions of the environment would vary across organizations within an industry but it was surprising to fad that managerial perceptions did not vary more substantially across countries. General managers in both countries perceived government regulator\`s actions to be the most uncertain environmental factor. Hotels in Japan were more geared toward external effectiveness than were hotels in Korea. The findings of this study also suggest that when the organization faces high environmental uncertainty, it places greater emphasis on extemally oriented functions such as market research and product development.

  • While numerous studies have suggested the significance of uncertainty during the process of information-seeking, less research has investigated user uncertainty in the actual search process using a real system. This study investigated user perceptions of uncertainty in the process of the selection of information retrieval system in the real information-seeking process. Considering the role of commercial Web search engines as supplementary tools for traditional bibliographic databases in academic research environments, this study analyzed the selection behavior of scholarly researchers, who use such search tools for their academic study. The researchers were limited to the discipline of science in order to understand user perceptions in this field. The findings revealed various dimensions, types, and incidents of uncertainty. Variations appeared in different incidents of uncertainty relating to the unique characteristics of the subjects' information-seeking context. The identification of three principal origins of uncertainty based on the different types of uncertainty generated implications to improve information systems and services.
