  • Objectives : Placebo phenomena have been considered as a confounding factor of clinical trial. Expectancy and belief of acupuncture have not been evaluated quantitatively. The present study was performed to analyze the emotional and cognitive factor .of acupuncture and investigate whether the expectancy of acupuncture treatment is associated with the cognition of acupuncture. Methods : The expectancy and the perception of bodily sensation (PBS) of 22 participants were assessed using self-reported questionnaire. The subjects used the self assessment manikin (SAM) to rate each of the standard affective image of the international affective picture system (lAPS) and other acupuncture-related image. Based on the degree of expectancy, the high expectant (HE) and the low expectant (LE) group were classified. The thermal and pressure pain threshold was objectively evaluated using radiant-heat device and algometer. The degree of expected pain of acupuncture and the actual pain of painful stimulation was subjectively evaluated using facial pain scales (FPS). Results : Using SAlVI analysis, we identified the negative correlation between hedonic valence and arousal dimension on acupuncture-related visual cue. The degree of the PBS and general pain threshold did not show any significant difference between the HE and the LE group. The HE group rated the acupuncture images as more pleasant, more arousing, than the LE group. In addition, we also found that the higher expectancy marked the lower FPS of the expected pain of acupuncture, but not of the actual pain of painful stimulation. Conclusions : Our preliminary study identified the psychological dimensions of acupuncture-related visual cue. These findings indicate that the expectancy of acupuncture could affect the cognition of acupuncture.

  • Impact of daylighting on the visual environment can improve occupant's well-being by providing visual comfort. Also, daylighting can save energy. However, glare from window can be a direct hazard to vision and can cause serious discomfort. Selecting glare source on a window plane is very important for evaluating discomfort glare from windows. But former glare indices can not identify the range of the glare source properly. In this study, difference in glare sensation with uniform and non-uniform glare sources are evaluated to identify the range of the glare source. The glare source was assumed as $120{\times}120[cm]$ window model. The window was divided into three parts with different luminance values. The experiment was conducted under 1[m], 1.5[m], 3[m] distance from the glare source. Two results were obtained from the experiments. First, the degree of discomfort glare increased as average window luminance increased. Second, the middle and lower part of the window plane can affect evaluation of discomfort glare as well as the upper part of the window plan. These results can be used for selecting the glare source in a window with non-uniform luminance.

  • Background : Central poststroke pain(CPSP) can occur as a result of lesion or dysfunction of the brain from stroke and may cause many difficulty in the social activities and daily life. In this study, we evaluate the clinical effectiveness of east-west medical management for CPSP through VAS(visual analogue scale), infrared themography, MBI(Moderfied Barthel Index) and Rankin scale. Methods : We treated thirty patients with oriental medical treatment method and western & oriental medical treatment method. Each group has fifteen patients of the CPSP. We evaluated their pain(characterizes tingling and burning sensation, aching, hyperalgesia, and allodynia) through VAS(visual analog scale) pain score, the skin temperature of pain site by infrared thermography and assessed their mobility & rehabilitation ability through MBI(Moderfied Barthel Index), Rankin scale before and after pain treatment. Results : The skin temperature of pain site was lower than non-pain site. The difference of skin temperature improved from $0.65{\pm}0.45^{\circ}C$ to $0.39{\pm}0.25^{\circ}C$ after oriental medical treatment and $0.68{\pm}0.54^{\circ}C$ to $0.27{\pm}0.24^{\circ}C$ after western & oriental medical treatment VAS scores improved from $7.9{\pm}1.4$ to $4.7{\pm}1.6$ after oriental medical treatment and $8.1{\pm}1.3$ to $4.6{\pm}1.2$ after western & oriental medical treatment. MBI scores improved from $61.40{\pm}13.58$ to $85.00{\pm}13.85$ after oriental medical treatment and $52.26{\pm}13.52$ to $77.13{\pm}12.04$ after western & oriental medical treatment. And Rankin scale scores improved from $3.33{\pm}0.72$ to $2.46{\pm}0.74$ after oriental medical treatment and $3.60{\pm}0.82$ to $2.66{\pm}0.81$ after western & oriental medical treatment Conclusion : The difference of skin temperature and Rankin scale scores more significantly improved after western & oriental medical treatment than oriental medical treatment. According to the results, we thought east-west medical management is very useful treatment for CPSP and rehabilitation of the patients with stroke.

  • This study was undertaken to determine the effects of SNAGs (sustained natural apophyseal glides) and visual convergence biofeedback on the proprioception and neck disability of patients with chronic neck dysfunction. A total of 31 patients with neck dysfunction were assigned to either SNAGs (n = 16) or biofeedback (n = 15). The groups were assessed for proprioception and neck disability, before and after the intervention. The SNAGs were performed using belt with flexion, extension and right-left rotation, whereas biofeedback training included visual feedback training with deep neck flexor. Intervention was implemented for 20 minutes, twice a week for 4 weeks. Biofeedback training a showed significant effect on the joint position sense (left and right rotation) as compared to the SNAGs group (p< 0.05), whereas neck disability index was significantly effective for SNAGs (p< 0.05). Ed. Notes: The previous statement lacked clarity. I have suggested the edit as per my understanding. Please review and revise appropriately, if required. Therefore, the SNAGs technique is effective for neck function, and biofeedback training is a positive intervention method for enhancing the proprioceptive sensation. In future studies on patients with neck pain, it may be possible to select an intervention method based on the characteristics of the disease.

  • Purpose : The purpose of this study was to investigate subjective symptoms according to the wearing, purchase and fitting status of soft contact lens wearers, and consumer perception of base curve. Methods : A survey was conducted for those who visited optical shops and lens shops in Seoul from June to August 2018. A total of 98 answer sheets they submitted were used for the analysis. The chi-square test and Fisher's exact test were used to compare subjective symptoms (dryness, glare, uncomfortable fitting, and decreased vision) according to whether fitting condition is screened (case history and push-up test, ect relevant to wearing sensation), and the odds ratio (OR) was obtained by the logistic regression analysis. Results : When the contact lenses were purchased, the rate of which the visual acuity test was performed was 86.6% at optical shop and 64.7% at lens shop. When purchasing contact lens and the contact lens was not tested for fitting, they more experienced dryness (OR 4.41, 95% CI 1.25-15.62) and uncomfortable fitting (OR 2.68, 95% CI 1.08-6.64) than testing for fitting. In addition, it was investigated that 87.8% of contact lens wearers did not know about the term base curve, 92.9% did not listen to an explanation related to the base curve when purchasing contact lenses, and 96.9% did not experience with base curve test. Conclusion : It would be thought that satisfaction of the contact lens fitting of existing consumers should be improved by changing a proper base curve by confirming the fitting condition when prescribing soft contact lens.

  • Purpose: Many factors influence the occurrence and severity of geriatric trauma, and regional weather is regarded as one factor that influences geriatric trauma. In this study, to predict the type, severity, and incidence of geriatric trauma patient, we analyzed the influence of regional weather on geriatric trauma. Methods: The subjects of our investigation were trauma patients over sixty-five years of age who visited the Emergency Department (ED) of Yeungnam University Hospital during a one-year period. We retrospectively reviewed the medical charts of 436 geriatric trauma patients, and the data were analyzed by using SPSS 12.0 for Window. The weather was based on data from the Korea Meteorological Administration. Results: The average age was 72.8 years old, and the ratio of males to females was 1:1.1. The mean spell out ISS was 10.8, and no difference was found between males and females. Slips were the most common cause of trauma. The largest numbers of aged trauma patients, 46, visited the ED in May, and the smallest number of such patients, 24, visited the ED in December. In addition to, summer saw the largest number of aged trauma patients. The type of trauma, the Injury Severity Score, and the number of patients had no relationship with season. On sunny days, the ISS was larger in patients who had hypotension and who had tachycardia. On rainy day, the ISS was larger in male patients and cultivator accident patients. The number of patients was larger on partly cloudy days. Conclusion: In spring and summer and on partly cloudy days, we must be prepared to treat aged traumatized patients in the E.D. On rainy days, visual sensation, tactual sense, and acoustic sense must be closely examined. In addition,on rainy day, aged male traumatized patients or cultivator accident patients must to be closely observation.

  • The study is about how the difference in education levels can affect the subjects' use of color and find out the features of the effect. This experimental study focused on the differences in color expression using the outline picture of a painting before and after being exposed to a full-color picture of the original painting. Differences between two conditions with two different stimuli were observed and the cause of the differences was analyzed based on the number of colors and the quantity of colors and composition of the colors used by the subjects. The study precedes an experiment based on how the level of education though experience can affect the use of colors. This study is focused on the various effects of color usage by children and adults who have various degrees of visual experience. In addition, the study analyzes how design majored subject differed in the use of color from non-design majored subject and compares the use of colors by the two groups. The results showed that design majored subject tended to use less coloring patterns after seeing the stimulus of the Monet picture with more colors, and included the colors from the stimuli they were exposed to. The non-design majored subject who viewed the Mondrian painting demonstrated opposite results by using less number of colors than before seeing the stimuli. In comparison to design majored subject, the variations in selected colors and the quantity of color by non-design majored subject were not consistent.

  • The process of making fashion accessories brings many benefits to visually impaired people. It helps the development of their tactile sensation, improves their aesthetic attitude, creativity, and imagination, and brings energy to their life. The current accessory making education in Korea is targeted to people with normal vision, and does not reflect the specific needs of the visually impaired. This causes a lot of trouble in educating the visually impaired. Therefore, this study aims to increase the efficiency of accessory making education by selecting curriculum and material that are appropriate and systematic for the visually impaired. In order to understand visual impairment, literature review was conducted to examine the definition and classifications of the impairment. Research was also done regarding material types and production method of fashion accessory. The study also designed an education program, including teaching guidelines, by referring to literature related to fashion accessory design, teaching guideline. The study conducted 12 experiments based on the results from April to June 2014. After revising and supplementing the teaching method, 2nd set of experiments were conducted from July to September 2014. Each class lasted for one and a half hour every week, and the class was composed of 6 students, 1 instructor and 1 volunteer. After each class, interviews were done to collect student opinions about the curriculum and material. Total experiment results and interview were reflected in constructing the final education program. The result of the experiments and interviews showed that selecting the accessory materials for class must be selected carefully. The visually-impaired students were very sensitive to the size, texture, shape, hole size of beads and length of material. After the experiments, all the students were able to distinguish the size and shape of the beads well, and finished the accessories using the given materials. The study verified that there is a need for another approach when educating the visually impaired about fashion accessory design. Many factors need to be considered from selecting materials to class contents. This study will contribute as a reference to fashion accessory making education as well as other design education for the visually impaired.
