  • Purpose: This study was conducted to verify the effects of a memory and visual-motor integration program for older adults based on self-efficacy theory. Methods: A non-equivalent control group pretest-posttest design was implemented in this quasi-experimental study. The participants were 62 older adults from senior centers and older adult welfare facilities in D and G city (Experimental group=30, Control group=32). The experimental group took part in a 12-session memory and visual-motor integration program over 6 weeks. Data regarding memory self-efficacy, memory, visual-motor integration, and depression were collected from July to October of 2014 and analyzed with independent t-test and Mann-Whitney U test using PASW Statistics (SPSS) 18.0 to determine the effects of the interventions. Results: Memory self-efficacy (t=2.20, p=.031), memory (Z=-2.92, p=.004), and visual-motor integration (Z=-2.49, p=.013) increased significantly in the experimental group as compared to the control group. However, depression (Z=-0.90, p=.367) did not decrease significantly. Conclusion: This program is effective for increasing memory, visual-motor integration, and memory self-efficacy in older adults. Therefore, it can be used to improve cognition and prevent dementia in older adults.

  • As the visual effect frequently used in movies or animations, special effects are well suited for the creation of buildings or materials' destruction and collapse scenes. With the relevant programs developing technologically, the adoption of a real-time physically based-system makes it possible to realistically express dynamic simulations. In the large scale, the visual expression of such effects of destroying is satisfying enough, but most common programs of those effects fail to maximize visual effect generated with the cutting of small materials. Besides, to perform a heavy simulation process needs high-performance hardware and programs, where high costs would become a serious issue. For this reason, this paper suggests a solution optimized for the effect of small materials-cutting. The progress of each step shows technologies which trace movement with the state of the completion of the character's motions and then cut the material in real-time, finally led to the very realistic visual effect. Besides, using vector inner calculation to follow the motions of object and to realize cutting effect, this study provides an experiment that constructs visual effect for visualization from the basis of mathematical algorithm and it would be certainly as an educational material used for further researches.

  • The purposes of this study are to look into the formative characteristics of the miniskirt and to evaluate the visual effects and images according to changes in the silhouette and length of the miniskirt from analyzing the mini skirt style shown in 2007 S/S domestic fashion. The miniskirt style shown in 2007 S/S domestic fashion was analyzed with pictures from a fashion website "Interfashion Planning" from Feb. to May of 2007. As a result, the basic lines of the miniskirt are classified into two types according to the side line. The lengths of miniskirts are classified into five steps of 25 cm, 27.5 cm, 30 cm, 32.5 cm, and 35 cm from the natural waistline. The stimuli were produced with imaginative sewing system 3D CAD of i-design series. For the visual evaluation according to changes in the silhouettes and length of the miniskirt, we used 13 pairs of items to find the visual effects, and 23 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. Formative characteristics of miniskirts can be found in the lines, colors, and materials that are the elements of fashion designs, colors and materials are the characteristics of the cloth that is the medium of the expression of designs. The result of factor analysis of visual effects and visual images according to changes in the silhouettes and lengths of miniskirts, the visual effect was composed of the three factors of the length of the lower body, the thickness of the lower body, and the shape abdomen and it was showed that these three factors occupied 63.6% of the total variance. The visual image was composed of four factors of elegance, personality, attraction, maturity and these four factors got 67.6% of the total variance.

  • The purpose of the study was to reveal the effects of visual organizer types and cognitive styles in electronic text understanding. 126 graduate students were divided into a field-dependent group and a field-independent group, and then assigned to two different types of web- based instruction programs which included visual organizers of 'reduction' type and 'abstraction' type. Regarding the comprehension of contents, there were no significant effects of visual organizer types and cognitive styles. However, it was revealed that there were significant interaction effects between visual organizer types and cognitive styles on the awareness of structure in electronic texts. That is to say, while Type 2 ('abstraction' type) was more effective to field-dependent learners, Type 1 ('reduction' type) was more effective to field-independent learners in awareness of structure in electronic texts.

  • In this study, I examined the psychological visual effect and clothes preference by clothes designs for the mid-aged Korean and American women's somatotypes. The psychological visual effects of each somatotypes' clothes are like these. First, the primary factors for psychological visual effect were analyzed into 5, neat, feminine, polished, modern and active. Second, in thin somatotype, Korean evaluated that china collar and V-neckline are the least feminine, and stand collar is the most polished and the modernest. American evaluated that V-neckline is the most feminine, and tailored collar is the modernest. It shows that there's the difference of culture. In standard somatotype, Korean thought stand collar with pants is the neatest, but tailored collar and china collar with pants are not neat. Contrary, they thought tailored collar with skirt is the neatest and stand collar with skirt is not neat. American thought tailored collar with skirt is the neatest and modernest. The neat visual effects are evaluated differently according to the clothes' styles of bottom. In obesity, Korean evaluated that tailored collar with skirt is the neatest and modernest, but stand collar with skirt is not modern. Stand collar with pants is the modernest, but tailored collar with pants is the least modern and active. American evaluated that round neckline with pants is not neat, modern and active, and round neckline with skirt is the modernest and the most active. So neckline's visual effects are differently showed by culture and the clothes' styles of bottom.

  • Two experiments were carried out to compare the suitability in visual tasks between cathode-ray tube (CRT) and thin film transistor-liquid crystal display (TFT-LCD). In the first experiment, the subjects were requested to detect pre-assigned target words or icons among distracters presented under time-invariant (static) image mode. The subjects' visual performance and fatigue were assessed while carrying out search tasks with dim and bright ambient light conditions. Significant interaction effects were found among displays, task types, and ambient light conditions. Due to visual fatigue, the subjects' accommodative power decreased in the end of task and the degradation was more significant for the CRT users and under bright ambient light. IN the second experiment, the subjects performed information processing task with time-varying road signs at a driving simulator to assess interaction effects between display types and changing speed of dynamic image. The perception time using TFT-TCD was shorter under slow image change while that of CRT was shorter rapid image change. Findings from this study suggest that, to improve visual task performance, users should carefully select their visual display type depending on the task to be performed.

  • Purpose: Hemiplegic patients usually present with difficulties in maintaining their balance. Balance retraining is a major component of a rehabilitation program for patients with neurological impairments. This study compared the effects of prorpioceptive exercise and visual feedback program on the limits of stability (LOS) in chronic hemiplegia patients. Methods: Thirty subjects (mean age $57.0{\pm}9.8$) were recruited. The subjects were divided into a proprioceptive group and a visual group. The subjects for the proprioceptive group participated in the proprioceptive exercise program for 4 weeks, and the visual group were treated with visual feedback training using a Balance Master. Results: At the 4 week follow-up test, the LOS in the proprioceptive group improved significantly in all directions (p<0.05). However, improvement was only observed in the forward direction in the visual feedback group. Therefore, the proprioceptive control approach improves the LOS in chronic hemiplegia patients. Conclusion: These results suggest that compared with physical therapy alone using a proprioceptive control approach to hemiplegia, there was no additional benefit of visual feedback training, such as Balance Master, when administrated in combination with other physical therapy interventions.
