As a result of conducting a 45 minute-long seminar on the principles, state of use, advantages, and disadvantages of nuclear power generation for Korean elementary, middle, and high school students, the levels of perception including the necessity (p<0.017), safety (p<0.000), information acquisition (p<0.000), and subjective knowledge (p<0.000), objective knowledge (p<0.000), attitude (p<0.000), and behavior (p<0.000) were all significantly higher. This indicates that education can be effective in promoting widespread social acceptance of nuclear power and its continued use. In order to induce behavior change toward positive judgments on nuclear power generation, it is necessary to focus on attitude improvement while providing the information in all areas related to the perception, knowledge, attitude, and behavior. Here, the positive message on the convenience and the safety of nuclear power generation should be highlighted.

Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

As the demand for ready-to-eat foods continues to grow, concerns about the sodium in processed foods are also growing. In this study, a survey was conducted on the perception of low-sodium products and diffusion plans according to the type of employee (manufacturer, retailer, distributor). Of the 191 responses collected, 189 valid responses (98.9%) were analyzed. The results showed that the employees were aware of the health contribution of a low-sodium diet, labeling for low-sodium, and the promotion of low-sodium food to increase its consumption. Furthermore, retailers recognized the positive contribution of low-sodium products in terms of Environmental, Social, and Governance (ESG) management. The use of sodium substitutes was preferred as the best way to reduce sodium in ready-to-eat foods. With regard to sodium reduction in ready-to-eat foods, we found that the technical factors involved were clustered by the type of business. Specifically, distributors showed a similar performance but had a lower perception of importance than retailers. Manufacturers had a lower perception of both importance and performance. In this study, we collected perceptions from employees who were working at food companies, which differed from previous research. We sought to examine the differences in the perception of sodium reduction and consumption of ready-to-eat foods across various types of employment. Furthermore, we provided specific approaches to reduce perception gaps and enhance understanding among employees.

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.
