Assessment of information credibility is a ubiquitous human activity given that people constantly make decisions and selections based on the value of information in a variety of information seeking and use contexts. Today, people are increasingly engaging in diverse online activities beyond searching for and reading information, including activities such as creating, tagging and rating content, shopping, and listening to and watching multimedia content. The Web 2.0 environment presents new challenges for people because the burden of information evaluation is shifted from professional gatekeepers to individual information consumers. At the same time, however, it also provides unprecedented opportunities for people to use tools and features that help them to make informed credibility judgments by relying on other people's ratings and recommendations. This paper introduces fundamental notions and dimensions of credibility, and contends that credibility assessment can be best understood with respect to human information behavior because it encompasses both the level of effort people exert as well as the heuristics they employ to evaluate information. The paper reports on a survey study investigating people's credibility judgments with respect to online information, focusing on the constructs, heuristics, and interactions involved in people's credibility assessment processes within the context of their everyday life information activities. Using an online activity diary method, empirical data about people's online activities and their associated credibility assessments were collected at multiple points throughout the day for three days. The results indicate that distinct credibility assessment heuristics are emerging as people engage in diverse online activities involving more user-generated and multimedia content. A heuristic approach suggests that people apply mental shortcuts or rules of thumb in order to minimize the amount of cognitive effort and time required to make credibility judgments. The paper discusses why a heuristic approach is key to reaching a more comprehensive understanding of people's credibility assessments within the information-abundant online environment.

Background: Colorectal cancer (CRC) is a leading cause of cancer death among Vietnamese Americans, yet screening remains underutilized. We investigated the effectiveness of a culturally tailored DVD intervention in promoting CRC screening among unscreened Vietnamese Americans age 50 and over. Materials and Methods: Using a community-based participatory research approach, we conducted a trial comparing twenty-eight subjects who received a mailed DVD in Vietnamese, with twenty-eight subjects who received a mailed brochure in Vietnamese. Subjects completed telephone surveys at baseline, One-month, and one-year. The primary outcome was receipt of screening. Secondary measures were participants' knowledge, attitudes, and beliefs about CRC screening. Two focus groups explored the intervention's acceptability and effectiveness. Results: At one year, CRC screening rates of 57.1% and 42.9% were observed in experimental and control group respectively (p=0.42), Subjects in both groups showed increased knowledge about CRC after one month. Focus group findings revealed that the DVD was an effective method of communicating information and would help promote screening. Conclusions: The findings suggest that culturally tailored, linguistically appropriate content is more important than the type of media used. This relatively low intensity, low cost intervention utilizing a DVD can be another useful method for outreach to the often hard-to-reach unscreened population.

Objectives : After analyzing the proficiency of medical communication of the students in College of Korean Traditional Medicine using standardized patients, we suggests ways to improve clinical practice in the future class and medical communication curriculum development. Methods : 20 students before clinical practice class (3rd grade) and 20 students after 1 year clinical practice class (4th grade) participated and did their medical interview on Standardized patient. They were evaluated on patient-physician communication skills by standardized patients and professor evaluator. In addition to be evaluated on patient-physician relationship, medical interview skills by professor evaluator. Results : As follows in the evaluation of clinical practice with standardized patients 1. More than half of the participated students regardless of their grade received poor score in their medical communication evaluated by SP(Standardized patient) and PE(Professor evaluator). 2. Greeting, History taking parts were higher in the 4th students who received 1 year clinical practice class, but verbal-nonverbal response, voice tone parts were higher in the 3rd students who do not received clinical practice lesson. 3. Pronunciation&Voice tone parts were higher in the male students but, gathering information part was higher in the female students. Conclusions : We think that the current clinical practice lessons are insufficient as a way to learn and improve medical knowledge and medical communication skills, and it is necessary a new form of clinical practice class. Participatory lesson using standardized patient could be a good alternative of that in the future class.

This study was performed in order to compare a change in pharmaceutical expenditures per outpatient of clinic and to analyze factors relevant to a systems as part of evaluating policies for the incentive scheme to reduce total prescribed drug expenditure and for the drug utilization review system("DUR system" hereafter). For this, it had finally analytical subjects as 21,320 clinics nationwide without a change in location, clinics symbol and signed subject during both terms of the first half of 2010 and the first half of 2011. As a result, the odds ratio with reduction in pharmaceutical expenditures of clinic was statistically higher significantly in the shorter year number of opening clinic, in the larger number of doctors, when the classification of establishment is other, not individual, and when the signed subject is surgical division. Also, the odds ratio was significantly higher in the less patient number of clinic and in the lower ratio of patients aged over 65. Finally, the odds ratio was significantly high when a clinic had been located in DUR system demonstrative project area. Through this, a case of policy for improvement in doctor's autonomous prescription behavior like DUR system can be known to be effective for reduction in pharmaceutical expenditures. A future research on evaluation of policy for pharmaceutical expenditure management system will need to be performed in-depth analysis in consideration of diverse characteristics on the participatory entities.

This study aimed to investigate the effects of learning with role-playing on student satisfaction and achievement regarding behavior management teaching in pediatric dentistry. 93 students were divided into 19 groups and randomly assigned to role-play as a doctor, patient, parent, assistant, or narrator. Their performances were evaluated by the instructor and the satisfaction survey was conducted. All participants took the written test and were asked to compare lecture and role-playing with regard to the effectiveness of learning. Statistical analysis was performed with Mann-Whitney U test, Independent T-test, and Kruskal-Wallis test. 68 students (73.1%) who believed that the role-playing was more helpful than lecture showed higher level of satisfaction than students who believed lecture was more helpful. But there were no differences in the tutor evaluation score and the written test scores. Participants in the patient management scenario showed higher level of descriptive question scores of the written test and tutor evaluation score than those who participate in the parent management scenario. There were no differences between the role groups. Role-playing may help students to become more interested and participatory in learning behavior management. The level of satisfaction may differ by the design and content of the scenario.

Business models in open market systems targeting smart phone users are determined by several important factors. First, by providing developers efficient technical platforms, it contains a setting for developers to learn, apply and improve the skills relating to the product category easily while they stay beyond a corporate boundary. Second, by the first condition, a huge population of talented developers becomes to join a specific open market where will invite more customers to use their applications. Hence it will attract more and more developer participants who will finally give a rise to a persistent market growth. Third, the evaluation system between platform providers and application producers, and one between application producers and application users may underlie the trust relationships between them. The research conducted a multiple embedded case study to test the success factors of open market based business models. It focused on smart phone game communities that have installed user evaluation, and feedback systems. The user innovation empowerment model within the social game networks has highlighted the theories on the roles and characteristics of lead users, and lead user network behaviors for future NPD participations.

Today, the civil society plays a key role not only in criticizing and monitoring the functions of the state and the market, but also as an active producer of public services by complementing the government and the public sector. Public records management is also becoming more and more popular. In the case of appraisal and selection, which is the core area of record management, discussions about citizen participation are becoming more serious than any other areas. The concept of 'proactive appraisal', which has emerged as a paradigm of citizens' participation in appraisal, reminds us that citizens themselves are the subjects of public records and are no longer alienated from the appraisal system. The problem is, while the growth of the Korean civil society about institutional participation is spreading rapidly, but citizen participation is hard to find in the field of public records. The purpose of this paper is to examine the role of citizen participation in the process of appraisal of public records, and to debunk the role of citizen participation in the appraisal processes by exploring the examples in the UK, Canada, and Australia. This paper emphasizes that the appraisal system of the national public records in crisis today could be largely restored through the domestic application of this active citizen participation cases. First of all, this study presents a conceptual appraisal model that could reflect citizen participation in the field of record management along with the analyses of the advanced cases in some western countries. Specifically, this paper focuses on presenting the models of 'appraisal documentation' and 'governance-based appraisal', reflecting the active citizen participation. This study suggests that these citizens' participatory evaluation models should be settled in Korea in the future and we should urgently discuss 'citizen participation appraisal'.

It is a study for the evaluation of the stability of the distribution automation system for the expansion of renewable energy. Through the Renewable Energy 3020 Implementation Plan, the government plans to expand new renewable energy and convert it to participatory energy that improves the quality of life of the people by 2030. The government has set a target of 20% of domestic supply energy for renewable energy generation by 2030. It is planning to establish more than 95 percent of its new facilities with clean energy such as solar power and wind power. By expanding the supply of renewable energy, new energy businesses and distributed power industry were fostered, and short-distance, low-voltage, and small-scale power generation were rapidly expanded rather than large-scale power development in the past. Due to this demand, the importance of power distribution facility operation has emerged and the need for distribution automation system is increasing. This paper discusses the development of a power distribution simulator for the performance and function evaluation of power distribution automation systems and presents the results of an interlocking test with the power distribution automation system. In order to introduce an advanced system into the power distribution system, it is necessary to take advantage of the transmission and distribution system. The DNP3.0 protocol is used in the distribution system and the IEC61850 protocol is used in the transmission and distribution system. It was concluded that the functions and performance of operations were satisfied when these two protocols are mixed and used in the distribution automation system.
