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.

Purpose : Skip the repetitive HRCT axial scan in order to reduce the exposure of patients during chest HRCT scan, Helical Scan Data into a reconstructed image, and exposure of the patient change and visually evaluate the usefulness of the HRCT images. Materials and method : Patients were enrolled in the survey are 50 people who underwent chest CT scans of patients who presented to the hospital from January 2015 to March 2015. 50 people surveyed 22 people men and 28 people women people showed an average distribution of 30 to 80 years age was 48 years. 50 patients to Somatom Sensation 64 ch (Siemens) model with 120 kVp tube voltage to a reference mAs tube current to mAs (Care dose, Siemens) as a whole, including the lungs and the chest CT scan was performed. Scan upon each patient CARE dose 4D (Automatic exposure control, Siemens Medical Solution Erlangen, Germany) was to maintain the proper radiation dose scan every cross-section through a device that automatically adjusts the tube current of. CT scan is the rotation time of the Tube slice collimation, slice width 0.6 mm, pitch factor was made under the terms of 1.4. CT scan obtained after the raw data (raw data) to the upper surface of the axial images and coronal images for each slice thickness 1 mm, 5 mm intervals in the high spatial frequency calculation method (hight spatial resolution algorithm, B60 sharp) was the use of the lung window center -500 HU, windows were reconstructed into images in the interval -1000 HU to see. Result : 1. Measure the total value of DLP 50 patients who proceed to chest CT group A (Helical Scan after scan performed with HRCT) and group B (Helical Scan after the HR image reconstruction to the original data) compared with the group divided, analysis As a result of the age, but show little difference for each age group it had a decreased average dose of about 9%. 2. A Radiation read the results of the two Radiologist and a doctor upper lobe and middle lobe of the lung takes effect the visual evaluation is not a big difference between the two images both, depending on the age of the patient, especially if the blood vessels of the lower lobe (A: 3.4, B: 4.6) and bronchi(A: 3.8, B4.7) image shake caused by breathing in anxiety (blurring lead) to the original data (raw data) showed that the reconstructed image is been more useful in diagnostic terms. Conclusion : Scan was confirmed a continuous, rapid motion video to get Helical scan is much lower lobe lung reduction in visual blurring, Helical scan data to not repeat the examination by obtaining HRCT images reorganization reduced the exposure of the patient.

자연채광은 건물 재실자에게 시각적 편안함과 쾌적함을 제공하여 건강성을 향상시키며 조명 에너지를 절약할 수 있는 중요한 조명환경 요소이다. 자연광에 의해 발생되는 창면에서의 글레어는 장시간 노출될 시 시각의 저하, 시각적 불쾌감의 원인이 된다. 창면에 의한 불쾌글레어 평가시에는 창면에서 글레어 광원을 어떻게 선별할 것인가가 중요한 문제이다. 기존의 불쾌글레어 평가법을 적용하더라도 글레어 광원을 한정할 방법이 없다. 따라서 본 연구에서는 글레어 광원 선별방법을 모색하기 위하여 불균일한 대광원의 휘도차가 불쾌글레어감에 미치는 영향을 검토하였다. 이를 위하여 $120{\times}120[cm]$의 정사각형 모형창을 제작하였다. 실험변수는 균일과 불균일한 휘도분포의 광원의 휘도비와 광원크기로 선정하였다. 실험방법은 모형창을 3분할한 후, 각기 다른 휘도비를 설정하여, 1[m], 1.5[m], 3[m] 거리에서 불쾌글레어를 평가하도록 하였다. 실험 결과 두 개의 결론을 얻었다. 첫째, 광원의 평균휘도가 증가할수록 불쾌글레어 평가값이 증가하였으며, 둘째, 창면 상부의 천공 부분만을 글레어 광원으로 볼 수 없으며 하부면도 블쾌글레어 평가에 영향을 주는 것으로 나타났다. 본 연구의 결과는 채광창으로부터의 불쾌글레어 평가 시 글레어 광원을 선택하는 기준으로 활용될 수 있을 것이다.

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.

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 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.
