  • Purpose: This research aimed to provide baseline data for undergraduate safety education by evaluating paramedic student risk perception and safety practice behavior regarding transport and disaster-related accidents. Methods: A total of 367 paramedic students at three different universities were surveyed using questionnaires. Risk perception questions about hazard, feeling of dread, and uncontrollable factors regarding seven items in transport and disasters were asked on a 7-point scale. Safety practice behavior consisted of 14 transport-related questions and 12 disaster-related questions in 4-point scale. All data were analyzed using SPSS Window 21.0. Results: Of 367 surveyed, 54.8% (201) were females, and 28.9% (106) were freshmen. In risk perception, 'drunk driving' in transport was the highest on average obtaining 6.49 points for hazard and 5.12 points for the feeling of dread. In disasters, 'war' recorded the highest average with 6.61 points for hazard and 5.71 points for the feeling of dread. In safety practice behavior regarding transport and disasters, a higher awareness of the need for safety education correlated with a significantly higher the rate of safety practice behavior (p <.001 respectively). Conclusion: The results indicate that undergraduates have inadequate perception of risk in emergencies. Safety education programs are needed to raise awareness of risks and to increase the safety practice rate.

  • PEAS (performance enhancement attitude scale) has been used to measure attitude and disposition toward doping in elite athlete. It is constructed of 17-item, 6-point scale. The purpose of this study was to verify validity of the PEAS for Korean elite player through Rasch model. The scale was administered to 438 Korean elite players. Principal component analysis was used to verify unidimensionality using SPSS program. Rasch measurement computer program, WISTEPS, was used to estimate goodness-of-fit of items and category structure. Differenctial item functioning by gender was also estimated by the WINSTEPS program. All alpha level was set at 0.05. First, principal component analysis showed that unidimensionality is satisfied as over 20.0% of variance of eigenvalue. Second, category probabilities curve showed 5-point scale was better than 6-point scaled statistically. Third, seven items (1, 9, 10, 12, 13, 14, 17) in the 17-item were not good model fit and three items (3, 12, 13) were estimated as the differential item functioning. This study showed that 9-item, 5-point scale is better PEAS to Korean elite player.

  • The objectives of this study are to develope sensibility image scales for Korean traditional motifs by quantitatively measuring their images and preference and to classify them into clusters. Data were collected via a questionnaire from seven hundred twenty five Korean undergraduate students. Re experimental materials were forty eight stimuli of Korean traditional motifs with different categories, interpretation types, composition types, and application objects. The instruments consisted of 7-point polar semantic differential scales of twenty three bipolar adjectives including preference. Data were analyzed by correspondence analysis, cluster analysis, ANOVA and Duncan's multiple range test. Re major results are as follows; image scales for textile patterns and dress designs using Korean traditional motifs were constructed. The axes of sensibility image scales for both textile patterns and dress designs were defined by quality level and degree of simplicity. Second, four clusters on the scale of textile patterns and two clusters on the scale dress designs were identified. Third, in the case of textile Patterns, the preferred cluster had high-quality and classical images, while the cluster that was not preferred had a complex image. In the case of dress designs, the preferred cluster had simple and high-quality images, while the cluster that was not preferred had complex and low-quality images.

  • Seven constructs of sanitary management :time temperature, storage, cross-contamination, personal hygiene, equipment facility and documentation management were evaluated to investigate the perceived performance of sanitary management for school food service managers, Using a four-part questionnaire containing the seven constructs of sanitary management HACCP program, demographic information and characteristics of food service facilities participants rated their self-perceptions regarding sanitary management. Of the 550 possible respondents, 248(45.1%) completed the study. For the perceived sanitary manage-ment variables, the participants rated them between 2.66 and 4.16(5-point Likert scale). Temperature management presented the lowest performances while storage management showed the highest. The number of years of work experience of the food service managers and the serving location correlated significantly to sanitary management variables. Documentation management was also highly correlated to the other sanitary management constructs. The respondents ranked the managers leadership and professional knowledge regrading HACCP as most important, followed by the facilitys supporting equipment and human resources second, to successfully implement the HACCP system at the school food service facilites, Awareness of this study indicating low performance on temperature management suggests an active training program is needed for sanitary management of school food service.

  • The objective of this study was to develop sensory lexicons that can be utilized for various types of tofu such as pressed, unpressed, and tofu made from germinated soybeans, using generic descriptive analysis. In the first phase of the experiment, trained descriptive panelists developed and defined the appearance, aroma, flavor, and texture attributes that are commonly present in tofu. Then, the sensory characteristics of seven types of tofu were analyzed using the sensory lexicons established in the initial stage of the experiment. Four appearance, 6 odor/aroma, 6 flavor/taste, 7 texture, and 4 aftertaste attributes were identified, and reference standards were established for most of the terms in order to facilitate the understanding of the attribute definitions. The intensities of the sensory attributes were measured on a 15-point scale. Statistical analyses, including analysis of variance and principal component analysis, were used for the data. The seven tofu samples showed significant differences in the intensities of 22 attributes. The unpressed tofu samples were generally rated as being high in moistness, easy to cut, silky, and easy to swallow. The pressed tofu, on the other hand, was salty, astringent, beany, hard, and rough in texture. The tofu made with germinated soybeans was characterized as having a strong cooked bean flavor, salty and astringent aftertaste, and hard texture. Overall, the attributes of moistness, easy to swallow, and silkiness showed strong positive correlations; hardness and sticks to teeth were also positively correlated to each other.

  • In this paper, we propose an image retrieval algorithm for real-time processing and design it as hardware. The proposed method is based on the classification of BoWs(Bag of Words) algorithm and proposes an image search algorithm using bit stream. K-fold cross validation is used for the verification of the algorithm. Data is classified into seven classes, each class has seven images and a total of 49 images are tested. The test has two kinds of accuracy measurement and speed measurement. The accuracy of the image classification was 86.2% for the BoWs algorithm and 83.7% the proposed hardware-accelerated software implementation algorithm, and the BoWs algorithm was 2.5% higher. The image retrieval processing speed of BoWs is 7.89s and our algorithm is 1.55s. Our algorithm is 5.09 times faster than BoWs algorithm. The algorithm is largely divided into software and hardware parts. In the software structure, C-language is used. The Scale Invariant Feature Transform algorithm is used to extract feature points that are invariant to size and rotation from the image. Bit streams are generated from the extracted feature point. In the hardware architecture, the proposed image retrieval algorithm is written in Verilog HDL and designed and verified by FPGA and Design Compiler. The generated bit streams are stored, the clustering step is performed, and a searcher image databases or an input image databases are generated and matched. Using the proposed algorithm, we can improve convenience and satisfaction of the user in terms of speed if we search using database matching method which represents each object.

  • Purpose: This study was performed to develop the Job Satisfaction Scale for Clinical Nurses (JSS-CN) and verify its validity and reliability. Methods: A preliminary 42-item version of the JSS-CN was developed through literature reviews and in-depth interviews. The draft scale was developed using thirty-seven items selected following content validity evaluation. Finally, thirty-three items with response options on a 5-point Likert scale were selected based on internal consistency reliability and construct validity. Subsequently, the test-retest reliability and convergent validity of the JSS-CN were verified. Results: Six factors, namely, recognition from the organization and professional achievement, personal maturation through the nursing profession, interpersonal interaction with respect and recognition, accomplishment of accountability as a nurse, display of professional competency, and stability and job worth, were identified, which explained 59.7% of the total variance. The JSS-CN's Cronbach's ${\alpha}$ for the total scale was .95, and the intra-class correlation coefficient was .90. The correlation coefficient between the scores of the JSS-CN and Slavitt's scale was .75, and that between the JSS-CN and job performance was .53. Conclusion: Results showed that the JSS-CN has good reliability and validity. Therefore, it is concluded that the JSS-CN could be a useful tool for the measurement of the job satisfaction of clinical nurses in Korea.

  • The purpose of this research is to study face images according to color of make-up was made by computer graphic simulation. The various facial images can be helpful for choosing suitable make-up color planning. In order to find out the differences of face images by make-up color, three different foundations and seven eye-shadows, six lips were applied on the round face model. Make-up Image Scale was used the scale of seven point modified the S-D method. Data were analyzed by Varimax perpendicular rotation method, Duncan's Multiple Range Test, Three-way ANOVA. As the result of make-up image perception analysis, a factor structure was divided into mildness, modernness, elegance, unique. The factor of mildness, modernness, unique affected on the foundation color. Foundation color was found out to be influential variable to distinguish color perception abilities. Also, the foundation, eye-shadow, lip color were influenced interactively on the perception of elegance factor. Pink color was important color, influenced on the mildness factor. Gray and purple color were influenced on the modernness factor. Mildness factor was perceived as the most bright foundation but unique factor was perceived as the most dark foundation. Then, the foundation, eye-shadow, lip color were influenced interactively on the perception of facial images. The results can be effectively applied to today's marketing and color design management which is focused on the product's emotional image in customer's mind.
