색채는 인간이 누릴 수 있는 지각의 세계에서 가장 뛰어난 심리작용과 정서적 반응을 일으킨다. 감성 시대에 살고 있는 우리는 다채로운 일상 속에서 다양한 색채에 의해 정서적 영향을 받으며 살고 있다. 색채의 정서적 반응은 색채를 시각화하는 과정에서 일어나기 때문에 개인마다 정서적 반응의 차이가 존재한다. 본 연구에서는 다수가 보편적으로 공감하는 색채의 특성을 고찰하여 애니메이션 <러브 라이브>에 등장하는 주요 캐릭터와 성격과의 관련성을 헤어컬러를 중심으로 분석하였다. 세 캐릭터의 성격과 그에 따른 헤어컬러의 조합을 주황색, 베이지색, 남색으로 선정하였고 그 결과로 각각 밝음, 편안함, 차분함의 이미지와 정서적 일치를 나타냄으로써 유의미한 결과를 도출하였다. 따라서 색채의 정서는 각 캐릭터에 부합하는 심리적 배경을 헤어컬러에 적용함으로써 스토리전개에 설득력을 뒷받침해주는 동시에 대중의 기억에 오래도록 각인될 수 있다. 이처럼 색채와 성격의 결합의 결과는 상호 밀접한 관련성을 나타냄으로써 자기표현의 기능을 넘어 내면반영의 정서적 기능을 통해 상당한 파급효과를 나타낸다는 것을 알 수 있다. 본 연구는 헤어컬러에 나타난 정서와 색채의 관계를 분석하고 색채의 특성을 재조명하는데 목적을 두었으며 인간의 ‘내면’ 자체를 주제로 한 연구로 인하여 그 한계점이 있으므로 신중을 기했다. 색채를 통해 느끼는 감정은 인간의 심리뿐만 아니라 인간의 시대적 사회상과 밀접한 관계에 있기 때문에 개개인을 주제로 끊임없이 변화하고 있다. 그러므로 차후의 연구에서는 한계점을 고려하여 기존 미용학적 영역에 색채학적 관점을 도입하여 보다 심층적인 연구의 가능성에 주목하고, 향후 헤어분야에서 성격유형에 따른 헤어컬러의 범주화된 체계적용이 필요하다고 사료된다. 나아가 본 연구를 통해 다양한 색채를 적용한 실제 매개체를 통하여 헤어컬러와 색채의 정서적 관계를 다각도로 다룬 연구가 행해져야 할 것이며 향후 현장실무에서의 체계화된 트랜드 개발에 도움이 되는 연구가치로 남기를 바란다. Color causes the most superior psychological and emotional responses in the perceptual world that human beings can enjoy. we live in the emotional age and live in various daily life with emotional influence by various colors. since the emotional response of color occurs in the process of visualizing color, there is a difference of emotional reaction among individuals. In this study, we analyzed the characteristics of colors that many people commonly sympathize with, and analyzed the relationship between personality and the hair color of animation characters Love Live. The characteristics of three characters and their hair color combinations were selected as orange, beige, and indigo, and the result showed significant emotional agreement with images of lightness, softness and calmness. Therefore, the emotion of color can be stored in the memory of the public for a long time while supporting persuasiveness in story development by applying the psychological background corresponding to each character to the hair color. The results of the combination of color and personality are closely related to each other, so that it can be seen that the emotional function of reflection gives a considerable ripple effect if it goes beyond the function of self - expression. The purpose of this study was to analyze the relationship between emotions and colors in hair color and re - examine the characteristics of color, and it was necessary to be cautious because there was a limit due to the study on the subject of the 'inner' of human being. The emotions that are felt through color are not only human psychology, but also are closely related to the social age, so they are constantly changing on individual subjects. Therefore, in future studies, it is necessary to apply the categorized system of hair color according to the personality type in the future hair field by paying attention to the possibility of further research by introducing the chromatic viewpoint to the existing cosmetic area in consideration of the limitation point. Furthermore, through this study, it is desirable to study the emotional relationship between hair color and color in various angles through actual mediators applying various colors, and hope to remain as a research value that will help develop systematic trends in the field in the future.

Heat transfer and momentum transfer under conditions of both oscillating flow and oscillating pressure within pulse tubes show very different behavior from those for steady state conditions. The analytic solutions of axial velocity and temperature of the gas within pulse tubes were obtained by assuming that the variations in pressure and temperature were purely sinusoidal and small. The shear stress and the heat flux at the tube wall obtained from the solutions are expressed in terms of the cross-sectional averaged velocity, the difference between mean temperature and instantaneous cross-sectional averaged temperature and the difference between mean pressure and instantaneous pressure. It is shown that the complex shear factor, which has been applied to momentum transfer of incompressible oscillating flow, and the complex Nusselt number, which has been applied to either heat transfer with oscillating pressure only or heat transfer of incompressible oscillating flow, could also be used for momentum transfer and heat transfer subjected to both oscillating flow and oscillating pressure, respectively.

A theoretical investigation to optimize thermoelectric elements for thermoelectric coolers was performed using a new one-dimensional analytic model. Mathematical expressions for the optimum current and the optimum length of a thermoelectric element, which maximize the coefficient of performance of thermoelectric coolers, were obtained. The optimum current is expressed in terms of the cooling load for a thermoelectric element, the hot and cold side temperatures and thermoelectric properties, but not the length of a thermoelectric element. The optimum current is proportional to the cooling load and decreases as the temperature difference between the hot and cold sides decreases. It is also shown that the optimum length of a thermoelectric element decreases as the cooling load increases.

While endoscopic submucosal dissection (ESD) is widely used to treat gastrointestinal tumors, it is rarely used for subepithelial tumors (SETs) originating from the muscularis propria of the esophagus and gastric cardia because of the risk of perforation and problems with inadequate space and field of view during procedures. Submucosal tunneling endoscopic resection (STER) is a new therapeutic method for treating SETs in specific locations in the esophagus and stomach. This technique is highly skill-dependent, using a mucosal flap that covers a deeper part of the gut wall, but is safe and minimally invasive compared with conventional endoscopic approaches such as ESD in SETs originating from the muscularis propria.We report a patient who underwent STER to remove a SET located at the gastric cardia. The patient recovered without any complications. We believe that our case shows the efficacy and safety of the STER technique for patients with a SET originating from the muscularis propria.(Korean J Gastroenterol 2015;66:340-344)

A two-dimensional model for pulse tubes with tapered cross-section was proposed. Net enthalpy flow and steady mass streaming were investigated by two-dimensional analysis of mass, momentum and energy equations of the gas as well as energy conservation of the tube wall. Steady mass flux profiles show good agreement with the previous approximate solution. It was shown that steady mass streaming can be reduced by tapering a pulse tube and by increasing the length of a pulse tube. Effects of the velocity phase angle and frequency on steady mass streaming were shown.

열성 질환의 동시감염은 각 질환의 유사한 임상양상으로 인하여 진단 및 치료에 있어 혼란을 가져온다. 국내 및 해외 학회에서는 동시감염으로 인해 진단 및 치료에 있어서 어려움이 있었던 예들이 보고되어지고 있으나 장티푸스와 렙토스피라병의 동시감염은 아직 보고된 바가 없었다. 저자들은 초기 항생제 치료에 반응을 보이지 않았던 장티푸스에서 렙토스피라병의 동시감염을 진단하였고, 항생제 병용으로 치료한 1예를 경험하였기에 보고하는 바이다. A 37-year-old male patient presented with a fever, chills, and abdominal pain. The patient was diagnosed with Typhoid fever based on blood culture, but did not clinically respond to standard antibiotic (Ceftriaxone) therapy. On day 9, leptospira serology was positive and doxycycline was added to the treatment strategy. With combination therapy, the patient recovered from the infection. In most cases, similar clinical presentations make the diagnosis of concurrent infections of febrile diseases difficult, and serious complications can develop as a consequence of delayed treatment. As with this case, if the patient initially has serious a medical condition caused by complications, and does not clinically respond to initial standard antibiotics therapy or has an unusual course of disease, concurrent infection must be considered.

Paradoxical embolism is a kind of stroke caused by embolism of thrombus of venous origin through a lateral opening in the heart, such as a patent foramen ovale (PFO). Although the most frequent manifestation of paradoxical embolism is cryptogenic stroke, noncerebral paradoxical embolism is also associated with PFO. We experienced a case of cryptogenic renal infarction in a previously healthy 70-year-old man. He had no cardiac thrombus on transthoracic echocardiography and electrocardiogram revealed a normal sinus rhythm. Because it was cryptogenic renal infarction, we performed transesophageal echocardiography with microbubble test. Microbubble test using agitated saline proved the presence of right-to-left shunt and patent foramen ovale was diagnosed. We also performed lower leg doppler ultrasonogram, but there was no evidence of deep vein thrombosis. Although only the presence of a right-to-left shunt is not enough to establish the diagnosis of paradoxical embolism, it is uncommon for the source of the embolism to be identified. In this case, we concluded that paradoxical embolism is the cause of renal embolism. We report paradoxical renal embolism through PFO with review of relevant literatures.
