In this study, by performing a survey targeting public libraries' users, we analyzed the most common path to acquire health information, the users' perception about if public libraries are needed to provide CHI services, and the factors that affect users' perceptions. The results are as follows: 1) About 90% of Korean public libraries' users do not take into account public libraries as the acquisition path for CHI resources. 2) About 60% of users thought that public libraries are needed to provide CHI services. 3) The factors that affect users' perception for the necessity of public libraries providing CHI services, were their interest in health and hours of using the internet per day. 4) In addition, we analyzed differences in perception between librarians and patrons about the necessity of public libraries providing the CHI services. The result showed that there was no significant difference in their perceptions, and both groups strongly felt that public libraries must provide the CHI services.

Relevance has a long history of scholarly investigation and discussion in information science. One of its notable concepts is that of 'user-based' relevance. The purpose of this study is to examine how users construct their perspective on the concept of relevance; to analyze what the constituent elements (facets) of relevance are, in terms of core-periphery status; and to compare the difference of constructions of two groups of users (information users vs. information professionals) as applied with a social representations theory perspective. Data were collected from 244 information users and 123 information professionals through use of a free word association method. Three methods were employed to analyze data: (1) content analysis was used to elicit 26 categories (facets) of the concept of relevance; (2) structural analysis of social representations was used to determine the core-periphery status of those facets in terms of coreness, sum of similarity, and weighted frequency; and, (3) maximum tree analysis was used to present and compare the differences between the two groups. Elicited categories in this study overlap with the ones from previous relevance studies, while the findings of a core-periphery analysis show that Topicality, User-needs, Reliability/Credibility, and Importance are configured as core concepts for the information user group, while Topicality, User-needs, Reliability/Credibility, and Currency are core concepts for the information professional group. Differences between the social representations of relevance revealed that Topicality was similar to User-needs and to Importance. Author is closely related to Title while Reliability/Credibility is linked with Currency. Easiness/Clarity is similar to Accuracy. Overall, information users and professionals function with a similar social collective of shared meanings for the concept of relevance. The overall findings identify the core and periphery concepts of relevance and their relationships in terms of coreness, similarity, and weighted frequency.

New information technologies have often been treated as innovations for target users. Although users in recent times have had significantly more opportunities to be socialized with information technologies, the rapid pace of technology development usually means that every new technology represents a fairly major change over the previous one. Although a fairly significant body of research that empirically tests these alternative models and theories is now in existence, some questions with regard to the role of perceptions in innovation adoption remain unanswered. This paper reports the results of a field study examining adoption of an information technology innovation represented by an internet application. Moreover, the study examines the effects of an important moderating influence-personal innovativeness-on this adoption process. Finally, the study seeks to shed further light on the determinants of perceptions by examining the relative efficacy of mass media and interpersonal channels in facilitating perception development.

At a time of growing importance of safety management in the social welfare facility by the increase of social welfare facilities, this study analysed safety perceptions about facility management, facility conditions, and facility structure and arrangement. This study sample consisted of 204 service providers and service users in 12 social welfare facilities. T-test and ANOVA were used to find the group differences among facility types. The findings were as follows. Firstly, safety perceptions of the service providers were significantly higher than those of service users in terms of facility management, and facility structure and arrangement. Secondly, in terms of facility types, the respondents in the family service center had lower safety perceptions than the respondents in other service in all three areas. Thirdly, facilities that are of 10 years or older had higher safety perceptions than the respondents of facilities that are 6 to 10 years old in the area of facility management, and facility structure and arrangement. Fourthly, in regard to building heights, the respondents in 3 to 4 story facilities had statistically higher safety perceptions than respondents in 1 story facilities. Finally, looking at the relationship between floor area and safety perceptions, safety perceptions of the respondents of less than $400m^2$ facilities or $600m^2$ and more facilities were significantly higher than those of $400m^2{\sim}$ less than $600m^2$ facilities.

The battery lifetime is one of the most important factors in product qualities of mobile devices such as mobile phones, MP3 players, PMP. It is used to be displayed by a 'battery bar' icon with uniformly divided three or four blocks. However, several manufacturers of mobile phones have assigned uneven time ratios to each battery block because they believe that it can make users feel more long in battery lifetime. In this study, two experiments were performed. The first is to verify the effects of the uneven time ratios in each battery block on users' cognitive awareness of battery lifetime. The second is to investigate whether the compatibility between battery displays and actual time ratios affects the users' time perceptions. The results show that as low battery bar is maintained for a long time, users tend to be aware of the battery lifetime shorter. On the contrary, maintaining full battery status longer does not affect the users' time perception. These results can be applied as the guidelines for determining proper time ratios in designing the battery bar indicator of mobile devices.

Background: The use of health functional food (HFF) is increasing and will continue to rise worldwide. Concerns about HFF-drug interactions are increasing as HFF are becoming more widely used. Therefore, awareness of consumers' perceptions and behaviors associated with HFF use may help health care providers improve their communications with patients. Purpose: The aim of this study was to assess the characteristics, perceptions, and behaviors associated with HFF use in South Korea. Method: The online survey was conducted from September 21th to October 7th, 2013. With the aid of Social Network Service (SNS) and google, the questionnaire was posted online on internet website targeting people aged 15 years or older so that self-reported data covering 4 domains were collected from 257 Koreans. Results: A total of 257 people responded the questionnaire. Among them, 81.3% reported experiences of HFF use. Female were more likely than male to use HFFs. There were no differences in demographic characteristics between HFF users and non-users in relation to age, education, and household income. Higher level of education was associated with high-level perception of HFF function (OR 3.9, 95% CI 1.48, 10.1) and a positive relationship was observed between the maximum number of HFFs used concurrently and age of the respondents. Among the HFF users, 42.6% reported concurrent HFF-medication use. However 73.3% of them did not disclose their use to physician or pharmacist and only 30.2% were informed about potential drug-HFF interactions. Pharmacy was most commonly reported as the source from which the respondents were informed about potential interactions. Conclusion: Many people had used HFF and medications concurrently while not being informed about potential HFF-drug interactions. Pharmacists and physicians should be vigilant for risk of the interactions and actively determine whether the patient is using an HFF before prescribing and administrating medications.

In a qualitative approach, this study investigated users' perceptions associated with their satisfactions in the process of using the scholarly resource search functions of the academic version of the NAVER search engine. For this study, the data was collected from a group of undergraduate students, who conducted academic information searches in the field of own major disciplinary areas, using the Web portal. Based on the data, students' satisfactions and dissatisfactions along with the reasons of their perceptions were analyzed. The results presented users' perceptions in various evaluation criteria based on the three major domains: system interfaces, retrieval mechanisms and search results. Based on the results, the study proposed the following suggestions: 1) the enhancements of the system interfaces and HELP guidances based the limited user knowledge on basic system terminologies 2) the improvements of the retrieval mechanisms associated with understanding the contexts of the search terms presented by users 3) the necessity of the user education due to the insufficient user knowledge of the retrieval mechanisms and the search functions.

Social networking services provide individuals with an easy approach for exchanging messages with others based on interpersonal relationships. However, why individuals spread marketer-generated content (MGC) in their online social circles remains unclear. Therefore, we develop a theoretical model to examine how social capital, intrinsic motivations, personal perceptions, past behavior, and personal traits influence MGC sharing behavior of social media users in micro-blogging context. Data collected from 319 social networking users support the proposed model. The results from partial least squares analyses show that enjoyment, perceived control, and outcome expectations are significant indicators of individual's MGC sharing intention in the social broadcasting environment. Results also suggest that social capital, users' intention, and past behavior positively influence the MGC sharing behavior of users. Moreover, individual prevention pride exhibits a significant interaction effect on the relationships between users' MGC sharing and its antecedents. Implications for research and practice are discussed.

This study aims to look at overall adolescents' perceptions of library and reveal the relevance of search engine sources and library sources compared each elements of them and find out any related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine over library as their information search tool, and they used library as primarily a source of information for printed materials such as books and most of them don't use the library often. Also the result shows the population users tend to select information when it is easy to get and fast to access. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources- have significant differences each other.

Currently, most academic libraries provide OPAC 2.0 service which applies Web 2.0 based-internet search engine to OPAC. The new service is for the users' convenience and so the considerations for the users' opinions are of great importance for each of services. The objectives of the study were to investigate perceptions of the students as the main user for academic library on the importance for the main services of OPAC 2.0 and analyzed information sources and the reasons for book search by the virtue of this service. The study showed that there were the users' high expectations on accuracy and satisfaction for OPAC 2.0, and the main searching information source was the OPAC of the universities to which the users belong due to familiar screen as well as convenient reading and book loan through it. The OPAC 2.0 service needs to be improved with the consideration of the users' opinions.
