Although many studies have suggested that introducing the distance learning method, including Web-based learning, to a practice class is effective, studies applying the distance learning method to subjects who are practicing cooking are rare. The purpose of this study was to determine the perception of the distance learning method, the degree of computer use, and the use of distance learning by college students with cuisine-related majors to practice cooking. The results showed that most students used the distance learning method, and that the method was positively perceived, as it was a great aid in learning. Most of the cooking information was obtained through the internet, and the most effective learning media for practicing cooking was "e-learning" using a computer. The most effective learning method for those who were practicing cooking was a "face-to-face learning method", because face-to-face type of teaching and learning was most universally recognized. Most of the students surveyed responded that using the distance learning method was a positive experience, indicating that cyber lectures could be applied at more universities for subjects practicing cooking.

Motion perception has been tremendously improved in neuroscience and computer vision. The baseline motion perception model is mediated by the dorsal visual pathway involving the cortex areas the primary visual cortex (V1) and the middle temporal (V5 or MT) visual area. However, few works have been done on the extension of neural models to improve the efficacy and robustness of motion perception of real sequences. To overcome shortcomings in situations, such as varying illumination and large displacement, an adaptive V1-MT motion perception (Ad-V1MTMP) algorithm enriched to deal with real sequences is proposed and analyzed. First, the total variation semi-norm model based on Gabor functions (TV-Gabor) for structure-texture decomposition is performed to manage the illumination and color changes. And then, we study the impact of image local context, which is processed in extra-striate visual areas II (V2), on spatial motion integration by MT neurons, and propose a V1-V2 method to extract the image contrast information at a given location. Furthermore, we take feedback inputs from V2 into account during the polling stage. To use the algorithm on natural scenes, finally, multi-scale approach has been used to handle the frequency range, and adaptive pyramidal decomposition and decomposed spatio-temporal filters have been used to diminish computational cost. Theoretical analysis and experimental results suggest the new Ad-V1MTMP algorithm which mimics human primary motion pathway has universal, effective and robust performance.

영상간의 유사도는 일반적으로 영상으로부터 추출한 특징벡터간의 벡터공간상의 거리를 계산해서 판단한다. 그러나 이러한 특징벡터가 유사도 계산을 위한 하나의 방법이지만 항상 인간의 유사도 개념을 충실히 반영하지는 않는다. 그러므로 현존하는 대부분의 영상검색시스템들은 각 특징간의 중요도를 선정하여 유사도에 반영하는 방법을 사용하고 있다. 본 논문에서는 영상검색을 위한 새로운 초기 가중치 설정과 갱신 알고리즘을 제안한다. 이를 위해서 먼저 데이터 베이스 영상을 인간의 인지도 판단에 의해 그룹화 한 후, 내부질의와 외부질의를 수행하고, 검색된 영상중 유사한 영상이 어느 그룹에 속하는지 알아내어 각 영상별로 유사도 계산에 필요한 최적 특징 가중치를 계산한다. 2000개의 영상 데이타에 대한 실험을 통해서 제안된 알고리즘의 우수성을 보인다.

Purpose: The purpose of this study was to examine knowledge, perception, safety climate and compliance with hospital infection standard precautions and to identify the factors influencing nurse's compliance with standard precautions. Methods: Using the structured survey, data were collected from 292 nurses working at 4 general hospitals in the metropolitan city Seoul in October, 2008. Data were entered and analyzed with SPSS 12.0. Results: The majority of nurses were female with a mean age of 27.8. The mean score for knowledge of standard precautions was 21.2 out of 25. The nurses lacked knowledge on reusable gloves or gowns. Nurses perceived use of protective devices may not only increase time strain but also hinder development of therapeutic relationships with patients. Of safety climate factors, lack of time was the most frequently reported barrier to compliance with standard precautions. Knowledge, perception, and safety climate explained 16.1% variance of compliance with standard precautions. Conclusion: To improve nurses' compliance with standard precautions, provision of education and support for safety climate are necessary.

This study was done to investigate the relationship between the perception of body image, body weight satisfaction or dietary behavior and self-rated health status in Korean college students. Subjects, 285 college students, were divided into three groups (healthy, normal, and unhealthy) according to the answer for the self-rated health question. Information about demographic status, self-rated health condition, height and weight, perception of body image, satisfaction of body weight, concern for body weight control, dietary behavior, nutritional knowledge, and health-related characteristics collected by a self-reported questionnaire. The proportion of men and women in each group was not significantly different. The academic year, major, experience of nutritional education, and type of residence were not significantly related with self-rated health but the pocket money range was significantly associated (p<0.05) with self-rated health. The proportion of subjects rated their health as unhealthy was the lowest in 210-300 thousand won pocket money range and was increased in less than 210 thousand won or over 300 thousand won pocket money ranges. There were no significant differences for age, height, weight and BMI between the groups. The body image perception and body weight satisfaction levels of healthy group was significantly higher than those of unhealthy group (p<0.01 and p<0.001, respectively), but the level of concern for body weigh1 control in healthy subjects was significantly lower than that in unhealthy subjects (p<0.05). The proportion of subjects reported as healthy was significantly increased with increased frequencies of following food behaviors; weekly use of protein foods (p<0.01), vegetables (p<0.05) and dairy products (p<0.01), and food habits such as "regularity of meal time" (p<0.01), "eating in moderation" (p<0.05), and "eating breakfast" (p<0.001). Overall results suggested that the college students have tended to have a better perception of health when they have better body image perception, body weight satisfaction and dietary behaviors.

Background: To identify work-family balance and level of happiness among married women dental hygienists in Seoul and Gyeonggi Province. The goal of this study is to use the outcome as basic data to determine the compatibility of dental hygienists with work and family, systems, and improvement of happiness levels. Methods: From July 3 to August 10, 2020, 250 dental hygienists in Seoul and Gyeonggi Province were targeted. The questionnaire comprised 65 questions, including general characteristics (perception of work-family balance, perception of work-family balance system, job satisfaction, parenting type, happiness level) whether or not they were implemented. The results were obtained through a self-control questionnaire. Results: The perception of work-family balance was significantly different in job rank and average income, while that of the work-family balance system had significant differences in workplace type, total work experience, current job work experience, childcare system status, and parental leave period. Happiness level and job satisfaction were significantly different in job rank, average income, and childcare system status. Additionally, the perception of work-family balance and that of the work-family balance system showed a positive correlation with job satisfaction and happiness level. Finally, the perception of married women dental hygienists toward work-family compatibility was determined, where the higher the satisfaction with the job, the higher the level of happiness. Conclusion: To improve the work-family balance and job satisfaction of dental hygienists and their levels of happiness, changes in social perception and improvement of the working environment such as proper staffing, flexible work systems, and incentive systems should be considered.

Purpose: To identify the differences in perception of and adherence to the COVID-19 social distancing behavior guidelines among health care workers, patients, and the general public and to use them to prevent the spread of COVID-19. Methods: From October 16 2020 to November 30, 2020, a survey was conducted among 85 health care workers, 85 patients, and 82 general public regarding the perception of and adherence to the COVID-19 social distancing behavior guidelines. Results: Patients scored significantly higher than the general public in the adherence to the COVID-19 social distancing behavior guideline, and there was no difference between health care workers and general public, and patients and health care workers. In the multivariate analysis, the factors that influence the adherence of the COVID-19 social distancing behavior guide were found in women and the perception of the COVID-19 social distancing behavior guideline. Conclusion: In order to promote the implementation of the COVID-19 social distancing behavior guideline, it is necessary to increase the perception of the COVID-19 social distancing behavior guideline and provide additional education in men. It is necessary to investigate the reason behind why men have low adherence to the COVID-19 social distancing behavior guideline.
