Purpose: The purpose of this study was to identify the level of knowledge about dementia and to find the related factors in middle-aged adults. Method: The research design was a descriptive study by using a constructive self-report questionnaire with 34 items. Data were collected from 397 middle-aged adults using structured questionnaire. Data analysis was done by SPSS/WIN Programs using frequency, range from minimum to maximum, percentage, mean, SD, ${\chi}^2-test$, t-test, ANOVA, and Duncan's Multiple Range test. Results: The rate of correct answer of middle-aged adults was 68.7%, showing the mid-level of knowledge about dementia. There were significant differences according to age, education, marital status, job, income, information and information sources for dementia in middle-aged adults. Conclusion: These results indicate that Korean middle-aged adults need more education and counseling on dementia. Further studies are needed to overcome regionalism in sampling of this study and to develop standard measuring tools for the level of knowledge about dementia.

The purpose of this study is to investigate the perception on fossil in elementary science 'Earth and Space' domain for elementary school students. For this purpose, the fossil perception inventory was developed. And the fossil perception was examined for random sampling of 5th and 6th grade 635 students. As a result, students chosen incorrect answer of the average 30.8% for questions of fossil perception. Over the average rate of incorrect answers in 20 questions were 8 questions(3 in the definitions for fossil, 2 in the creation of fossil, 2 in the fossil, sedimentary, stratum, 1 in the understanding for fossil). When the results were analyzed by residence and grade, there were significant differences in 7 questions between students in urban and rural areas, and between 5th and 6th students, there were important contrasts in 4 questions. The data that understanding of elementary students fossil can be provided for form the basis planning the teaching method to correct student's scientific concepts in elementary school. The results are also contributed to find an effective way for modify misconceptions of fossils to the scientific concepts.

Purpose: The purpose of this study was to develop an instrument to assess emergency room nurses' knowledge and performance of triage nursing. Methods: The instrument was developed through the stages of conceptual construction, item development, and validity and reliability testing. For the validity and reliability testing, data collected from 48 emergency room nurses using questionnaires was analyzed through descriptive statistics, factor analysis, and reliability coefficients. Results: The knowledge part consisted of 30 items in nine areas, and its reliability was low (KR-20 =0.50). The correct-answer rate was 71.8%. The performance section derived from the factor analysis was composed of two factors with nine items in the triage domain and three factors with 12 items in the non triage domain. The explanatory powers of these factors for the domains were 66.1% and 70.4%, respectively. The overall reliability (Cronbach's ${\alpha}$) was .95, and the reliabilities for the two domains were .88 and .91, respectively. The nurses' mean performance level was 3.2(${\pm}0.45$). Conclusion: The specific contents of the triage nursing work were identified from the developed scale; further research is necessary to in order to develop a scale capable of higher reliability and validity.

As the use of digital media is becoming more universal and is being used in early-childhood education, understanding the effects of digital media on development is required. The purpose of this study was to examine whether child performance on a spatial cognition task depends on the type of media used to present the task and if the effect of media type is different depending on child's age and sex. To do this, a spatial cognition task set (consisting of direction, rotation, symmetry, conjugation, and part/whole tasks) was prepared, and these tasks were presented to 60 3-, 4-, and 5-year-old children using paper- and tablet-based measures. Our results showed that the correct answer rate of task performance differed significantly when completing the task on a tablet than when completing the task on paper. Generally, response times when completing the tasks on a tablet was significantly shorter than when completing the tasks on paper. Although there was no interaction between the type of media and age, and partial interaction was found between the type of media and sex. This result implies an influence of digital stimulation on child performance on the spatial cognitive task. This study provides a basic understanding for follow-up studies to examine the consequences of exposure to digital stimulation.

This study investigated the difference of the university students' recognition, attitude, and knowledge level of health by the health education in Daejeon and Chungnam province. First, in the survey analysis result regarding the health related recognition, the students who had attended lectures of health education were surveyed not only to have higher health related recognition than the students who did not have attended the lecture of health education, but also to appear meaningful in statistics by showing significance level p<0.05 in total score. Second, in the research regarding the health related attitude, the attendance or nonattendance of health education lecture were surveyed not to have high effect on the attitude of daily lives of the university students. Third, in the analysis of health related knowledge, the knowledge level between the students who had attended lectures of health education and who did not have attended the lecture of health education showed that the students who had attended lectures of health education got more excellent correct answer rate. In this survey result, the students who had attended lectures of health education showed higher health related recognition and knowledge than the students who had not attended lectures of health education.

Purpose: This study was done to identify the level and correlation of knowledge and practice of fever management at home and provide data for the development of an intervention program to improve the fever management ability of mothers of preschool age children. Methods: Participants were 112 mothers with children between 1 and 6 years of age and attending one of three daycare centers located in J city. The participants had a history of using medication and tepid massage. Data were collected during April, 2016. Results: The mean scores were 27.55 (correct answer rate 70.64%) of 39 for knowledge, and 75.93 of 92 for fever management practice. There were significant differences in scores for knowledge according to the number of children and number of visits to doctors for treatment of a fever. There were no differences in scores for practice. There was a positive correlation between knowledge and practice. Conclusion: Results indicate that mothers' knowledge and practice of childhood fever management were insufficient to provide accurate management of childhood fevers. Therefore, to improve the mothers' ability to provide appropriate fever management, educational strategies that focus on increasing knowledge need to be developed.

Decision making for gas boiler consumers depends on the characteristics of products such as the price and quality as well as the brand image. Although a gas boiler is a high involvement product in terms of price, in fact, it is a low involvement product which is greatly affected by installers. This study examined variables which affect the level of satisfaction and repurchase intention by surveying about 1,000 housewives through an on-line questionnaire. The results were as follows: first, gas boiler users' general knowledge of gas boilers showed a correct-answer rate of 54.5%. The average satisfaction score of product quality (mean=5.61 out of 7) was higher than that of the satisfactionscore of the company's service (mean=5.46). Second, the level of repurchase intention was above the mid-point (mean=4.72). Multivariate regression found that product satisfaction, service satisfaction, household size, and information sources explained repurchase intentions for gas boilers to be about 50.7%. Gas boiler marketers should pay attention to the survey result in that the level of repurchase intention depends mainly on both consumer satisfaction and information sources.

The purpose of the study was to investigate relationships among food safety training, knowledge, and practices of school food service employees. A questionnaire that identified employees' food safety training experience, knowledge, and practices was developed based on a review of literature. A total of 341 Korean school food service employees participated in the survey; the final usable responses were 293 (a response rate: 86%). Statistical analyses were conducted using SPSS for Windows (version 10). Most of the respondents (> 86%) took training sessions on 'proper hand washing' and 'proper food storage temperatures', whereas less than 60% had training on 'monitoring procedures and corrective actions at critical control points'. The mean score of their food safety knowledge was 8.02 out of 11. The majority of the employees knew correctly 'potentially hazardous foods (93.2%)' and 'diseases and symptoms with which they are excluded from working (87.0%)'; less than 50% chose a correct answer for 'sanitizing food contact surfaces.' A chi-square analysis revealed that the employees' actual knowledge did not differ significantly by whether they had food safety training (at the level of a =0.01), except one topic 'diseases and symptoms with which they are excluded from working.' Their self-reported practice scores were rated as 2.98 - 3.39 based on a 5-point Likert-type scale (1-not at all, 5-always). Employees' food safety training should be conducted continuously and repetitively to improve the effectiveness of the training.

It is well known that urgency resulted from time stress can be a great cause to industrial accidents. Therefore, time stress has been studied in the aspect of macroscopic view, namely industrial safety management, but has not been studied in microscopic view such as psychophysiological approach. Among diverse psychophysiological indices, Electroencephalogram(EEG) would be on of the most objective psychophysiological research technique on human errors though few research has been taken yet. This study aimed to get characteristics of human error while committing a simple arithmetic addition task by utilizing the power spectrum technique of EEG data. Each experiment was composed of 2 tasks under different condition - with and without time stress. As subjects, 5 young undergraduate students in their early twenties participated in this study. The results advocated a well-known fact that time stress downgrades the performance of human workers. However, correct answer rate and response time were not significantly influenced by time stress factor which might be explained by the constructural factor adopted in the present study. As in the previous studies, among various EEG-related measures, relative band power ratios of ${\alpha}$ and ${\beta}$ waves to sum of ${\alpha}$,${\beta}$,${\theta}$ wave powers, namely $P_{{\alpha}/({\alpha}+{\beta}+{\theta})}$ and $P_{{\beta}/({\alpha}+{\beta}+{\theta})}$ seemed to be the most effective measures to grasp variation of brain activities in time-stressed situation so that discussions were expanded about their variations.
