This study proposed a color scheme that is harmonious with the working environment of industrial sites using Birren's color harmony theory for color planning. To apply the Birren's color harmony theory to working clothes, the basic colors were chosen, and six of the eight harmony formulas of Birren excluding achromatic colors (white + grey + black) and solid color harmony (solid colors + white + black) were used to form a palette for each case. For the basic colors, the color chips of four dominant colors (yellow-green, sky-blue, blue, and violet), which were chosen from a field survey for preferences in the first step, and the production of materials in the second step were collected through the PANTONE color chips. The selected color chips were PANTONE 13-0550 TPX, PANTONE 15-4105 TPX, PANTONE 18-3949 TPX, and PANTONE 19-3720 TPX. These color chips were scanned and their RGB values were extracted through Photoshop CS. Then the colors were arranged in accordance with the Birren's color harmony formulas (Color+Tint+White, Color+Shade+Black, Tint+Tone+Shade, Shade+Tone+Black, Shade+Tone+White, and Tint+Shade+Tone+Gray). In addition, the proposed palette color schemes were applied through Birren's color harmony formulas using Texpro V 10.1 textile to the schematization of working clothes that were designed in the previous study. Palette formation in line with Birren's color harmony formulas provided scientific color arrangement results. Visually presenting the color scheme of working clothes will help the color selection of working clothes in tune with the circumstances of industrial sites.

본 논문에서는 군용 항공기의 시각 탐지(visual detection)를 지연시키는 위장기술에 대하여 조사하였다. 위장(camouflage)이란 관찰자에게 드러나 보이지 않도록 어떤 물체를 거짓으로 꾸미는 것으로 정의할 수 있다. 그러나 군사적 관점에서의 위장은 완전히 사라지게 하는 것이라기보다는 관찰자의 탐지시간을 연장하거나 탐지가능성(detectability)을 낮추는데 목적이 있다. 기본적으로 항공기 위장은 항공기 위치 탐지를 지연시킬 뿐만 아니라, 관측자에게 항공기의 속도와 고도, 진행방향에 대한 혼란을 유발하여야 한다. 따라서 저(低)탐지기술 또는 위장기술은 군용 항공기의 생존성 향상에 많은 영향을 미치므로 많은 연구가 지속적으로 진행되었다. 근접 지원 항공기 및 제공 전투기의 경우는 다색(multi-tone) 위장패턴과 반음영(counter-shaded) 위장패턴이 일반적으로 적용되고 있다. 아울러, 단색(mono-tone) 위장패턴 역시 색상(hue)과 명도(brightness)가 적절히 조절 및 조합되었을 때 위장효과가 큰 것으로 나타났다. 항공기의 위장 성능 향상을 위한 능동 시각 위장 기술(active camouflage techniques)에 관한 연구도 진행되었다. 특히, 발광 반사율이 높은 발광 장치를 사용하는 Counter-illumination 기술은 항공기 표면과 배경 하늘의 명도차를 최소화하여 위장 효과를 향상시켰다. 이와 같은 능동 시각 위장 기술은 시각 탐지에 비교적 취약한 저고도 무인기의 생존성 향상에 기여할 것으로 기대된다.

The purpose of this study is the effect of massage therapy on the human autonomic nerve system by heart rate variability spectral analysis. This study were to effect autonomic nerve system before and after massage therapy in 12 health peoples. The effect of massage therapy were assessments through Heart Rate Variability (HRV; SA-2000E, Medicare, Korea) before and after the massage therapy by same massage therapist. Statistical techniques for data analysis were applied paired t-test. The 0.05 level of significance was used as the critical level for rejection of the null hypotheses for the study. On the basis of the results analyzed in this study, conclusions were drawn as follows; Rest Heart Rate was significantly decreased before and after massage therapy, but other variable were no statistical significances. These results suggest that massage therapy maybe be effective in reducing heart rate and activity in valgal tone.

티베트 고원에서 살고 있는 티베트인 또는 장족은 오랜 역사와 자연환경에 순응한 자신만의 독특한 생활양식을 가지고 있어 독자적인 의복문화 형태를 지닌다. 복식 중에 색채, 문양, 도안의 사용에서 종교적인 의미를 나타낼 뿐 아니라, 복식을 통해 자신의 생활의 희망과 자연을 존중한 마음을 강하게 표현하고 있다. 티베트 민족 복식의 색채 상징성에 관한 고찰을 통하여 티베트족 문화의 특수성을 이해하고자 장족 복식에 사용된 색채를 분석하고 그들만의 색채의 의미를 고찰하였다. 장족의 색채인식, 상징성을 색의 사용 예시와 출현빈도를 중심으로 살펴보았다. 연구방법으로는 복식사진의 색채 수집 및 분석을 실시하였는데 I.R.I HUE-TONE 시스템에서 매칭 색상과 색조를 찾는 방식이었다. 장족 복식도서의 칼라사진과 청해 장족문화박물관의 장족 복식을 직접 촬영한 사진, 인터넷 박물관의 복식사진 등 총 96장의 사진이었다. 결과는 첫째, 세상을 구성한다고 생각하는 가장 주요한 요소를 5가지 색 장오색에 연결하여 각 색마다 자연적 의미를 부여하는데, 빨간색은 불, 파란색은 하늘, 흰색은 구름과 흰 눈, 초록색은 초원, 노란색은 대지를 각기 상징한다. 둘째, 홍과 녹, 흑과 백, 홍과 남, 황과 자색 등 강렬한 색채조화를 이루도록 대담한 색채를 사용하고 있는 것이 특징이다. 셋째, 티베트인들의 특유한 심미관을 표현하는데 색의 일반적인 감성을 대부분 따르지만 그들만의 감성이 들어있는 색상이 존재하였다.

It is intended to study the colors of work environment and the working clothes colors between humans and environment with application of the arrangement of working clothes colors to domestic machinery companies that play pivotal roles in the industry of Korea. The purpose of this study is to provide the foundation of color plan for the integrated environmental harmonization and the safety of industrial sites by analyzing the photographs of working clothes in the sires in consideration of the functions of colors (clearness, attention-getting, and safety) using the Faber Birren's Color Harmony and by analyzing the result of a questionnaire survey. The study was conducted by the method to shoot a worksite using a digital camera after wearing 24 sets of uniforms, which were developed by the color plan established in a previous study, in the same worksite. The shooting place was an outdoor steel sheet inspection site of D company, a machinery company in Changwon-si, Gyeongnam, and the intensity of illumination was 2400lux. 24 pieces of images were printed in 5x7 inch size and a questionnaire survey was performed at 5-point scale. The questionnaire survey was performed for 13 subjects consisting of 6 field professionals having more than 30 years of experiences, 4 clothes color professionals, and 3 industrial engineering professionals. The result of the survey was statistically analyzed by the method of frequency analysis using IBM SPSS Statistics 20 Program. As the result of assessment of basic four colors (yellow green, sky blue, blue, and violet) of working clothes, yellow green, sky blue, and blue showed high mean values in (Tint)+(Shade)+(Tone)+(Gray) equation indicating that its is a harmonized equation.

Haze or fog is a common natural phenomenon. In foggy weather, the captured pictures are difficult to be applied to computer vision system, such as road traffic detection, target tracking, etc. Therefore, the image dehazing technique has become a hotspot in the field of image processing. This paper presents an overview of the existing achievements on the image dehazing technique. The intent of this paper is not to review all the relevant works that have appeared in the literature, but rather to focus on two main works, that is, image dehazing scheme based on atmospheric veil and image dehazing scheme based on dark channel prior. After the overview and a comparative study, we propose an improved image dehazing method, which is based on two image dehazing schemes mentioned above. Our image dehazing method can obtain the fog-free images by proposing a more desirable atmospheric veil and estimating atmospheric light more accurately. In addition, we adjust the transmission of the sky regions and conduct tone mapping for the obtained images. Compared with other state of the art algorithms, experiment results show that images recovered by our algorithm are clearer and more natural, especially at distant scene and places where scene depth jumps abruptly.

Background: The purpose of this study was to investigate the effects of joint mobilization and muscle strengthening exercises on neck function, range of motion, and muscle tone in patients with forward head posture. Methods: A total 32 subjects were divided into muscle strengthening exercise (n=16) and joint mobilization (n=16) who met the diagnostic criteria for the forward head posture, and the study method used the neck disability index (NDI) and BPM Pro to compare the range of motion. Results: As a result of the study, there was no significant difference between each group, and when looking at the differences before and after each group, there was a significant difference in neck pain in both groups. There was a significant difference in muscle tension in the joint mobilization group, but there was no significant difference in the muscle strengthening exercise group. In the range of joint mobilization, there was a significant difference in the range of left joint mobilization of the joint mobilization group, there was no significant difference in the range of right joint mobilization, and there was no significant difference in the range of joint mobilization of the muscle strengthening exercise group. Conclusion: The above results revealed that joint mobilization and muscle strengthening exercises were effective on neck function, range of motion, and muscle tone in forward head posture patients.
