Objective: In general, macular degeneration, cataracts and glaucoma generally cause visual injury in clinical settings. This study aimed to examine the effects of low visual acuity simulations on hand manual dexterity function and brainwaves in healthy young adults. Design: Cross-sectional study design Methods: This study was an observational, cross-sectional study. Seventy healthy young adults participated in this study. To evaluate the effects of low visual acuity simulations on hand function and brain waves, this study involved four different visual conditions including (1) normal vision, (2) simulated cataracts, (3) simulated glaucoma, and (4) simulated macular degeneration. The hand function was measured to use the Minnesota manual dexterity test (MMDT), and the brainwaves was also measured to use the electroencephalography. Results: In hand function, placing and turning performance on the MMDT in the normal visual condition was significantly different than that in the cataract and macular degeneration conditions (p<0.05), and the placing performance was significantly differred in the normal condition than that in the simulated glaucoma. However, turning was not significantly different in the normal condition than that in the simulated glaucoma. The alpha, beta, and gamma waves did not significantly differ among the four visual conditions (p>0.05). Conclusions: The results suggest that limited visual information negatively affects the ability to perform tasks requiring arm-hand dexterity and eye-hand coordination. However, the effectiveness of low visual acuity on the brainwaves should be further studied for rehabilitative evidence of visual impairment.

This article aims to evaluate the visual effects and images according to the changes in the width of pleats of accordion pleats skirt. I altered the width of the pleats to seven categories in changes of 0.5cm, 0.7cm, l.0cm, 1.3cm, 2.0cm, 2.5cm and 3.0cm. For the visual evaluation, seven stimuli had been placed in mannequins, and had been estimated by experts in fashion design. For the visual evaluation according to changes in the width of pleats of according pleats skirt. I used 11 pairs of items to find their visual effects, and 17 pairs of adjectives to measure the visual images. Those stimuli and adjectives had been randomly given to evaluators and had been evaluated by the seven-point Likert type scale. The data have been analyzed by frequency, factor analysis, ANOVA, Scheffes test and correlation analysis. According to factor analysis of the visual effects of the accordion pleats skirt, the result was classified into three factors: the verticality of the lower body, flexuosity of the lower body, and shape of the abdomen. According to factor analysis of the visual image of the accordion pleats skirt, the result was classified into the following three factors: activity, attraction and neatness. In visual effects, the verticality of the lower body had been assessed as the most important factor of all. The visual effect was positive when the width of pleats had been narrowed. In visual image, activity had been assessed as the most important factor.

The purpose of this study is to evaluate the differences of visual effects by variations in the shoulder length and puff volume of the puff sleeve blouse. The stimuli are 21 samples: 3 variations of the shoulder length and 7 variations of the puff volume. The data has been obtained from 40 fashion design majors. The data has analyzed by Frequency, Factor Analysis, ANOVA, Scheffe's test and MCA method. The result of the study are as follows. The visual effects by the shoulder length and puff volume are composed of 4 factors : the width of the upper body, the shape of the breast part, the shape of the neck part and the shape of the upper arm. In these factors, the width of the upper body is estimated by most important factor. In view of the visual effects by variation of the shoulder length, the shorter shoulder length goes, the more positive visual image comes in the shape of the breast part. In comparison of the differences of visual effects by the 7 variations of puff volume, the arm looks thin and long when the puff volume goes enough and the breast part has a better visual assesment in case the puff volume goes poor. In the interaction effects between the shoulder length and puff volume, the shoulder length have significant differences in the shape of the breast part, the shape of the neck part and the shape of the upper arm and puff volume has significant difference in the width of the upper body.

The purpose of this study is to evaluate the differences of visual effects by variations in the location and width of the waist band of one-piece dress. The stimuli are 24 samples: 8 variations of the location of the waist band and 3 variations of the width of the waist band. The data has been obtained from 50 fashion design majors. The data has analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: According to the result of factor analysis of the visual effects based on the changes in the location and width of waist bands for one-piece dress, four factors were identified - verticality of whole-body, horizontality of upper-body, curves of lower-body and shape of breast. Whole-body verticality and upper-body horizontality were found to be the most important factor among them. In all of the four factors of the visual effects, significant differences were observed according to the location of the waist bands for one-piece dress. The visual effects were evaluated positively when the waist bands were positioned above the natural waist line and negatively when the waist bands were positioned below the natural waist line. In addition, significant differences were observed in the visual effects according to the width of waist bands when the waist bands were positioned above the natural waist line, and visual effects were better when the band width was 3.5cm and 4.5cm than the others. The interaction of the visual effect showed significant differences in horizontality of upper-body, curves of lower-body and shape of breast.

In the modern society, GIS-based decision support system has been used in evaluating environmental issues and changes due to spatial and temporal analysis capabilities of the GIS. However without proper manual of these systems, its desired goals could not be achieved. In this study, audio-visual SWAT tutorial system was developed to evaluate its effectives in learning the SWAT model. Learning effects was analyzed after in-class demonstration and survey. The survey was conducted for $3^{rd}$ grade students with/without audio-visual materials using 30 questionnaires, composed of 3 items for trend of respondent, 5 items for effects of audio-visual materials, and 12 items for effects of with/without manual in learning the model. For group without audio-visual manual, 2.98 out of 5 was obtained and 4.05 out of 5 was obtained for group with audio-visual manual, indicating higher content delivery with audio-visual learning effects. As shown in this study, the audio-visual learning material should be developed and used in various computer-based modeling system.

This study will explore the reenactment of visual special effects used in TV dramas. The subjects of the study are images that are reproduced in visual special effects through and . Accordingly, we looked at the changes in the way TV dramas were produced according to the times, and looked at the changes in the market. Also, we looked at cases of visual special effects of Korean dramas, and looked at expressions according to the degree of completion of visual special effects. For the purpose of the analysis of the research targets, the images of reproducibility and the flow through reality were analyzed. In the case of , the period setting is realistic, but visual special effects were used to maximize the actor's safety and expression, and in the case of , the visual effects were used to maximize the aesthetic of the period background. In addition, it can be seen that the visual special effects were used for the effect of PPL on the export of images. This shows that the emphasis of reality and image montage techniques are being used to pursue hyperrealism. It is now possible to actively express and use the beauty of TV dramas rather than technical limitations. In addition, the pursuit of realism can actively express the changing times of digital age. This is an active representation of the camera's angle, lighting, and perspective that coincides with the background. The environment of video production is crucial for realistic expressions. The study examined various visual directions and applications. In TV images, we looked at reproduction, which can make a natural period of time by combining. As a follow-up study, we are going to study the changes in the new quadratic image based on the present image representation.

The purposes of this study are to look into the formative characteristics of the bolero and to evaluate the visual effects and images according to changes in the line and length of the connecting lines of the neck, center front, and hem lines from analyzing the bolero style shown in 2005 S/S domestic fashion. Theoretical examination of the bolero was made philologically with reference books, theses and some articles. And the bolero style shown in 2005 S/S domestic fashion was analyzed with pictures from a fashion magazine "Ceci" and a fashion website 'Interfashion Planning" from Feb. to Aug. of 2005. As a result, the basic lines of the bolero are classified into three different categories according to the connecting lines of the neck, center front line, and hem line. We altered the length of the bolero in three categories with the changes in the waistline-5 cm, 8 cm, and 11 cm. For the visual evaluation, 9 stimuli were placed in mannequins, and were estimated by the experts in the fashion design. For the visual evaluation according to changes in the line and length of the bolero, we used 12 pairs of items to find the visual effects, and 13 pairs of adjectives to measure the visual images. The stimuli and adjectives were randomly given to the evaluators and were evaluated by the 7-Point Likert Type Scale. Data we got from this experiment was analyzed statistically by using the SPSS 12.0 and practiced the Factor Analysis and Correlation Analysis. In the current women's garments, the bolero is a new fashion item which combines with jackets or cardigans. Usually the bolero jacket is made out of a cotton, denim, leather or fur, and the bolero cardigan usually used knitted materials. The design could be very varied depending on the roundness of the center front line, and hem line. According to the result of factor analysis of the visual effects of the Bolero, four factors were identified the whole silhouette, neck line, breasts and shoulders. According to the result of factor analysis of the visual image of the Bolero, three factors were identified maturity, tenderness, neatness.

Based on the importance of visual representation for scientific understanding, this study applied visual thinking in elementary science classes. This study analyzed elementary students' visual thinking and investigated the instructional influences. Students' perceptions on the class applying visual thinking were also investigated. The subject were 38 fourth grade students, 18 in experimental group and 20 in control group. For the unit of 'Shadow and mirror', on-line and off-line blended classes were applied in both group because of COVID-19. The experimental group student were asked to construct their own visual thinking, while the control group students used traditional workbook. The results were as follows. First, students' visual thinking can be classified into three different types, which are 'activity recall type', 'result summary type', and 'core concept representation type' based on what they represent rather than how they represent. Second, applying visual thinking in science class showed significant effects on science academic achievement, science related attitude, and creative academic efficacy. Third, students' perceptions on applying visual thinking in science classes were very positive. Students perceived visual thinking activities were interesting and helpful for understanding science. Educational implications of applying visual thinking in elementary science classes were discussed.
