BACKGROUND/OBJECTIVES: This study aimed to improve portion size estimation aids (PSEAs) used in the nutrition survey of the Korea National Health and Nutrition Examination Survey (KNHANES) and validate the accuracy and precision of the newly developed aids. SUBJECTS/METHODS: We conducted intensive interviews with survey experts in KNHANES and consulted with experts to collect opinions about improvement of PSEAs. Based on the results of the interviews, 5 types of PSEAs (rice bowl, earthen pots, mounds, measuring spoons, and thickness sticks) were newly developed using 3-dimensional (3D) modeling or modification of color or shape. Validation tests were conducted with 96 adults 20 years old or older. For the rice bowl and earthen pots, the participants were asked to select the more similar PSEA in size after being shown the real dishes. For the mounds, measuring spoons, and thickness sticks, the participants were presented with actual plates of food and asked to estimate the given portion sizes using the given PSEAs. RESULTS: The improved 2-dimensional (2D) picture aid for the rice bowl reflecting the size distortion by angle of view using 3D modeling was perceived more closely to the actual size than the current 2D picture (P < 0.001). The change of the color of 2D pictures and 3D models, the change of shape of the measuring spoons, and the 3-dimensionalization of the 2D mounds had no significant improvement in the subjects' perception. CONCLUSIONS: The currently used 2D PSEAs need to be fully redesigned using 3D modeling to improve subjects' perception. However, change of color or shape will not be necessary. For amorphous foods, it is suggested that more evaluation be performed before reaching a final conclusion in the use of PSEAs, or alternative ways to improve accuracy of estimation need to be explored.

We investigated how combining different types of images with written text affects the comprehension of health related information. The types of images were picture, photograph, and X-ray. 47 four year college students were recruited for the experiment. The independent variables in this study included information presentation format, vividness of image, and the degree of awareness for the disease. The dependent variables were recognition and recall for information. The results showed that the information with images in recognition and recall had higher score than information with written text only. In regard to the effect of different kinds of images on comprehension of health information, information with picture had higher score than the information with photograph and X-ray. The vividness of image were found to work as a negative factor on the recognition of information. Finally, the degree of awareness of disease also failed to have any significant effect on subjects' recall and recognition. This research has implications for the contents design of health related website.
The purpose of this study was to examine the usability of a robot in kindergartens and the children's perceptions of that robot. In order to answer these questions, a field study, picture drawing and interviews were conducted over twelve days in a kindergarten located in Seoul. Our results indicated that children were likely to use the robot in a group and girls tended to use it more than boys. Children's affection towards the robot was positive and they perceived the robot mostly in terms of a friend. Finally, the picture drawing activity differed according to the usability level. Children who were in the high usability level grouping engaged more with educational content and storytelling while the low usability level grouping utilized the robot for singing in a large group.
During design thinking and developing, its idea into the real world, and we are under pattern recognition and gestalt principles of perceptual organization. Generally originality is a part of creativity which consists an integral factor of the designing. This is a study on the measure system for an ability of originality in design. It is reorganized that the OTLD(Originality Test of Line Drawing) is a measuring system for personal originality. In order to catch the development the thoughts, we presented 10 picture planes as stimuli (each picture plane contained 3-18 dots), recorded the tape displaying eye-mark trajectories and outputting the trajectories with EMR(Eye Mark Recorder), then found the process of visual sensation and perception. From the results of this study, we examined the relationships between connections and complexity of the objects on the picture plane, which could be transformed into some objective measuring parameters. We would suggest this OLTD as a measurement system for an ability of originality in design fields, but we couldn't find any reliability and validity for fine art fields.
In the development of linear perspective, Brook Taylor's theory has achieved a special position. With his method described in Linear Perspective(1715) and New Principles of Linear Perspective(1719), the subject of linear perspective became a generalized and abstract theory rather than a practical method for painters. He is known to be the first who used the term 'vanishing point'. Although a similar concept has been used form the early stage of Renaissance linear perspective, he developed a new method of British perspective technique of measure points based on the concept of 'vanishing points'. In the 15th and 16th century linear perspective, pictorial space is considered as independent space detached from the outer world. Albertian method of linear perspective is to construct a pavement on the picture in accordance with the centric point where the centric ray of the visual pyramid strikes the picture plane. Comparison to this traditional method, Taylor established the concent of a vanishing point (and a vanishing line), namely, the point (and the line) where a line (and a plane) through the eye point parallel to the considered line (and the plane) meets the picture plane. In the traditional situation like in Albertian method, the picture plane was assumed to be vertical and the center of the picture usually corresponded with the vanishing point. On the other hand, Taylor emphasized the role of vanishing points, and as a result, his method entered the domain of projective geometry rather than Euclidean geometry. For Taylor's theory was highly abstract and difficult to apply for the practitioners, there appeared many perspective treatises based on his theory in England since 1740s. Joshua Kirby's Dr. Brook Taylor's Method of Perspective Made Easy, Both in Theory and Practice(1754) was one of the most popular treatises among these posterior writings. As a well-known painter of the 18th century English society and perspective professor of the St. Martin's Lane Academy, Kirby tried to bridge the gap between the practice of the artists and the mathematical theory of Taylor. Trying to ease the common readers into Taylor's method, Kirby somehow abbreviated and even omitted several crucial parts of Taylor's ideas, especially concerning to the inverse problems of perspective projection. Taylor's theory and Kirby's handbook reveal us that the development of linear perspective in European society entered a transitional phase in the 18th century. In the European tradition, linear perspective means a representational system to indicated the three-dimensional nature of space and the image of objects on the two-dimensional surface, using the central projection method. However, Taylor and following scholars converted linear perspective as a complete mathematical and abstract theory. Such a development was also due to concern and interest of contemporary artists toward new visions of infinite space and kaleidoscopic phenomena of visual perception.
This study was performed in order to examine the effects of one to one interactive picture book reading on infants' reading response and teachers' language teaching efficacy. A total of 50 2-year-olds from 8 child care centers in Incheon were divided into an experimental group and a control group. The interactive picture book reading activities were carried out once a week during 12 weeks. The infants in the experimental group read one-to-one with teachers, and their counterparts read the same book in a group. The change in teachers' language teaching efficacy was examined, and their subjective perception was evaluated through in-depth interview. As a result of this research, the infants in the experimental group showed significantly increased verbal response, compared to the control group, both in the total score and most sub-factors such as naming, responding, asking, demanding, spontaneous utterance, and decontextualized utterance. They also represented a significant rise, compared to the control group, in the total score of non-verbal response and factors like finger indicating, imitating, and accepting. Finally, the teachers who led the experimental group showed increased language teaching efficacy, and evaluated the effects of interactive picture book reading with infants very positively.

The purpose of this study is to examine how elementary pre-service teachers have a perception of 'science'. Especially, this study used photo-narrative method to analysis pre-service teachers' perception of 'science'. Photo-narrative is a way of describing what a study participant wants to say by taking a picture. Participants were 66 elementary pre-service teachers. The results of this study were as follows: First, elementary pre-service teachers used many words such as people, life, everyday as well as scientific terms such as phenomena and principles to explain science. Secondly, the pictures used by elementary pre-service teachers to explain science included household goods, natural phenomena, advanced devices, and living things. Third, elementary pre-service teachers explained science with knowledge of science, knowledge, convenience, and nature of science. As a result of this study, it was found that elementary pre-service teachers recognized that science is closely related to life and that it is necessary for learning. The results of this study can contribute not only to curriculum composition and curriculum content of elementary and middle school science education but also to curriculum development for teacher training.
Background: This study aimed to evaluate the efficacy of external vibrating devices and counterstimulation on a child's dental anxiety, apprehension, and pain perception during local anesthetic administration. Methods: This was a prospective, randomized, parallel-arm, single-blinded interventional, clinical trial. One hundred children aged 4-11 years, requiring pulp therapy or extraction under local anesthesia (LA), were recruited and allocated equally into two groups (1:1) based on the interventions used: Group BD (n = 50) received vibration using a Buzzy® device {MMJ Labs, Atlanta, GE, USA} as a behavior guidance technique; Group CS (n = 50) received counterstimulation for the same technique. Anxiety levels [Venham's Clinical Anxiety Rating Scale (VCARS), Venham Picture Test (VPT), Pulse oximeter {Gibson, Fingertip Pulse Oximeter}, Beijing, China)] were assessed before, during, and after LA administration, while pain perception [Wong-Baker Faces Pain Rating Scale (WBFPS), Visual Analogue Scale (VAS)] was evaluated immediately after injection. Statistical analysis was performed using the Student's t-test to assess the mean difference between the two groups and the repeated measures ANOVA for testing the mean difference in the pulse rates. Statistical significance was set at P < 0.05. Results: Significant differences in mean pulse rate values were observed in both groups. In contrast, the children in the BD group had higher diminution (P < 0.05), whereas the mean VCARS and VPT scores were conspicuous (P < 0.05). Based on the mean WBFPS and VAS scores, delayed pain perception after LA injection was more prominent in the BD group than in the CS group. Conclusion: External vibration using a Buzzy® device is comparatively better than counterstimulation in alleviating needle-associated anxiety in children requiring extraction and pulpectomy.
Background: Injections are one of the most fear-provoking stimuli in dentistry. Painless administration of an injection is a vital step in alleviating anxiety, which in turn leads to good behavior in children. The aim is to evaluate and compare anxiety levels and pain perception using conventional, insulin, and deception syringes during the administration of local anesthesia in children. Methods: Forty-five children aged 6-12 were selected using a standard sample size formula and equally divided into three groups. Local anesthesia was administered using a conventional syringe to Group A participants and an insulin syringe for Group B participants. Group C participants were administered local anesthesia using a deception syringe by showing the patient disposable obturation tips, and eventually a conventional syringe was used for administration of local anesthesia after hiding them from the patient. Anxiety levels were assessed using Venham's Picture Scale and pulse rate at baseline and after administration of local anesthesia. The Wong-Baker Faces Pain Rating Scale was used to assess pain perception after the administration of local anesthesia. Results: Insulin and deception syringes showed better reduction in anxiety levels and pain perception than conventional syringes, demonstrating a high statistically significant difference. Conclusion: The use of insulin and deception syringes for administration of anesthesia was demonstrated to be effective in alleviating anxiety in children and is therefore recommended as an alternative to conventional syringes.
Purpose. This paper is derived from a larger study of nurses' perceptions of their role as patient educators. The focus is to examine nurse' performance in patient education in relation to issues of their perceived responsibility and their ability to prioritize patient education. Method. A multiple-method survey design, using a questionnaire and in-depth interviews, is used to produce a comprehensive picture of the research problem examined. Result. The findings suggest that although nurses consider patient education as an integral part of their care, they fail to deliver as much as they desire in the face of work constraints. Nurses' patient education activities are mainly informal and reactional, in which case they can be easily regarded as a low priority when faced with time constraints. Conclusion. The findings suggest that there is a need for systematic approaches that enable the inculcation of patient education into routine daily care.
