The purpose of this study is to estimate human sensibility quantitatively under color stimulation. We measured biological signals such as EEG, ECG, skin conductance and the number of respiration and eye blinking that were compared with color sensibilities mutually. Our result showed that red, yellow and violet color provoked active and exciting senses dominatively and blue, cyan, pink, and black color were involved in tranquil and resting emotions deeply. Our quantitative estimations of color sensibilites are useful in the design of manufactured goods and color therapy.

Purpose: We examined the effect of dual-task and single-task training on serial reaction time (SRT) task performance to determine whether SRT is based more on motor or perception in a dual-task. Methods: Forty healthy adults were divided into two groups: the dual-task group (mean age, $21.8{\pm}1.6$ years) and the single-task group (mean age, $21.7{\pm}1.6$ years). SRT task was conducted total 480 trial. The four figures were presented randomly 16 times. A unit was set as 1 block that would repeat 10 times. Thus, there were a total of 160 trials for each of the three color conditions. The dual-task group performed an SRT task while detecting the color of a specific shape. The end of the task, subjects answered the specific shape number; the single-task group only performed the SRT task. The study consisted of three parts: pre-measurement, task performance, and post-measurement. Results: Differences of pre and post reaction time between two group was higher for the dual-task group as compared to the single task group and there was a significant interaction between time and group (p<0.05). Conclusion: Our results indicate that. short term period SRT is not quiet effective under dual-task conditions, individuals need additional cognitive processes to successfully navigate a task This suggests that dual-task training might not be appropriate for motor learning enhancement, at least when the training is over a short period.

The advantage of the distance learning universities based on the 4th Industrial Revolution is that anyone can conveniently take lectures anytime, anywhere on the web. In addition, research has been actively conducted on the effect of light color and temperature control upon student performance during online classes. However, research on how the conditions of subjects, lighting colors, and music selection improve the degree of a student's concentration during online lectures has not been completed. To solve these problems in this paper, we have developed automatic analysis system SW for the weak subjects of learners by applying intelligent analysis algorithm, have proposed and simulated music therapy and art therapy. Moreover, It proposed in this paper an algorithm for an automatic analysis system, which shows the weak subjects of learners by adopting intelligence analysis algorithms. We also have presented and simulated a music therapy and art therapy algorithms, based on the blended learning, in order to increase students concentration during lecture.

자신이 느끼는 것이나 보는 것, 경험하는 것을 언어로 표현하는 것이 서툰 아동들에게 있어 미술 활동은 감정을 표현할 수 있는 방법 중 하나이며 미술 치료를 위한 중요한 분석 대상이기도 하다. PC의 그림판 기능 등을 통한 디지털 그림이 일상화된 최근에는 기존의 색채학 이론과 미술 치료 이론이 접목되고 있으며 자동 분석 기능의 필요성이 대두되고 있다. 본 논문에서는 아동이 그린 그림에 대해 주조색 분석을 하고 ART2 알고리즘을 적용하여 색채 정보를 군집화한다. 군집화된 각각의 중심 벡터값을 기반으로 색채 빈도수를 소속 함수에 적용하여 퍼지화한다. 퍼지화된 중심 벡터 값을 퍼지 추론 규칙에 적용한 후에 비퍼지화를 수행한다. 비퍼지화된 값을 분석한 후에 주조색과 보조색을 결정하여 알슈울러와 해트윅의 단일 색채에 따른 심리 상태와 색상 조합의 심리상태와 비교한 결과, 거의 비슷한 결과가 도출되는 것을 확인하였다.

본 연구는 일상 속에서 스트레스를 관리할 수 있는 VR 컬러테라피 힐링콘텐츠 '노르니르'를 구현하고 이를 제안한다. '노르니르'는 CRR 분석법을 적용하여 사용자가 선택한 3가지 컬러에 따라 맞춤형 VR 컬러테라피 체험의 여정을 제공한다. 사용자는 해당 컬러 여정을 통해 자신에 대해 이해하고, 앞으로 실천할 목표를 다양한 색채 인터랙션과 자극으로 제공받으며, 스트레스 수준을 낮추는 힐링이 가능하도록 설계하였다. 구현된 결과를 바탕으로 콘텐츠 시연 후의 사용자의 스트레스 변화를 확인하기 위해 한국판 기분 상태 검사 'K-POMS'를 실험 참가자들을 대상으로 시연 전후에 실시하였다. 실험 결과 사용자들은 부정적 감정의 감소와 긍정적 감정의 증가를 뚜렷이 보였다. VR 기술을 활용하여 색채심리치료룰 접목하여 일상에서 잦은 스트레스에 노출되는 사용자들의 스트레스를 완화 시켜줄 수 있는 가능성을 제시하였다.

Purpose: The present study purposed to examine induced characteristic or erythema and safety by medium wave ultra violet(UVB) lamp. Methods: We compared sunshine and UVB lamp using spectroradiometer and UV radiometer. For measuring sunshine irradiation, we used spectoradiometer and detected from 8 to 18 o'clock every each hour on the beach, playground and rooftop of a 5 story building. The subjects for erythema examination were 5 healthy subjects who have no pathologic history of photosensitivity reaction, psoriasis and vitiligo. They were exposed to UVB radiation at the abdominal area for 2 hours and after irradiation, we observed the change of skin color every 12 hours over a period of 1 week. Results: Between sunshine and UVB lamp, sunshine had higher data on the chromaticity coordinates, dominant and peak wavelength, bandwidth and purity than the UVB lamp but on the color temperature, brightness the UVB lamp had higher data than the sunshine. In comparison of sunshine and UVB lamp, UVB lamp irradiated constantly such as $3.9-4.4{\mu}W/cm^2$ at a distance of 100cm between bed and lamp which was same as early morning irradiation on the sunshine. The erythema didn't appear to any subject. Conclusion: This results suggest that the UVB lamp has lower irradiance as much as early sunshine. Therefore the UVB lamp had no influence of inducing erythema at a distance of 100cm between bed and lamp.

한의학은 진단 및 치료에 있어 뛰어난 우수성을 가지고 있음에도 불구하고 서양의학에 비해 선호도가 떨어진다. 이는 질병 진단에 있어 객관적인 진단 결과를 제공해 주는 서양의학에 비해 한의학은 임상의의 직관에 의존하고 있기 때문이다. 따라서 한방 임상의들의 직관을 객관화하여 기기로 구현 한다면 한방에 대한 선호도 상승 및 한의학의 세계 시장 진출도 크게 증대할 것으로 여겨진다. 특히 한의학의 진단법 중 가장 뛰어난 진단법으로 평가되는 망진의 경우 다른 진단법에 비해 관련 연구가 거의 이루어 지지 않고 있다. 이는 망진의 가장 중요한 요소인 찰색에 있어 실제 색의 분석을 위한 디지털 기기에서의 색 분석 기준이 없기 때문이다. 이를 위해 본 논문에서는 찰색을 기기로 구현하기 위한 절대적인 색 기준의 설정을 제시하고자 한다. 따라서 색 분석을 위해 여러 가지 디지털 색체계를 비교 분석하여 찰색을 위해 어느 디지털 색체계가 가장 효율적인 색 체계인지를 제시하고자 한다. 아울러 실험 환경의 차이에 따라 발생할 수 있는 변수를 최대한 줄이기 위한 실험 환경 및 조건에 대한 표준화를 제안하고자 한다.

Objectives : This study is designed to improve the practical possibility using Blood-Letting therapy through reviewing the literature recorded in the Donguibogam. Methods : Records on Blood-Letting therapy have been extracted from Donguibogam. First all articles containing the key words 'Hyul (血)' and 'Rak (絡)' have been extracted. Of them, records associated with Blood-Letting therapy had been sited and classified in terms of searching patterns for the Blood-Letting area, instruments for Blooding-Letting, cautions and side effects for the practice, applicable symptoms, acupoints/extraordinary acupoints, and Blood-Letting areas. Results : The regions capable of Blood-Letting are generally engaged with abnormal skin color such as black, bluish red, dark purple, dark blue, etc, and localized collection of fibrous exudate. There are several instruments used for Blood-Letting therapy; Samreongchim (三陵鍼), Chogyong (草莖), Pichim (鈹鍼), Lodaeguan (蘆管尖), Sachim (砂鍼), Saechim (細鍼), Gichim (?鍼), Eunjam (銀簪), nail, etc. Several cautions and side effects of the Blood-Letting therapy are presented. The Blood-Letting therapy could be applied to broad spectrum of symptoms. Body parts being applied were not only several acupoints but also effective points of the body. Conclusions : This study shows that Donguibogam represents Blood-Letting therapy in clear fashion so as to enhance the convenience and its practicality.

최근에 색상에 관한 인간의 감성과 심리상태에 대한 많은 연구가 진행 중이며 색채 심리 치료의 필요성이 급증하고 있다. 그중에서 아동의 그림은 자신의 감정을 표출하는 수단이 될 수 있다. 그림에 사용된 색채는 무의식적으로 자신의 내면 심리 상태를 나타내는 경우가 많고 또한 색채의 밝기에 따라 심리상태가 다르다. 본 논문에서는 퍼지추론을 사용하여 색채이미지 공간 순색의 분류 및 밝기 정도에 따른 세분화를 통해 주조색을 추출하는 방법을 제안하고 실험을 통하여 아동 그림에서의 주조색에 따른 심리적 의미를 분석할 수 있음을 보이고자 한다.
