많은 칼라 장치에서 동일한 영상을 출력했을때, 재현된 색들은 장치 사이의 색역 차로 인해 많은 차이를 나타내므로 이를 개선하기 위한 많은 색역 사상 방법들이 제안되었다. 본 논문에서는 기존의 장치 의존적 색역 사상의 단점인 압축 사상에서의 불필요한 왜곡을 줄이고 절단 사상에 의한 색 분별력 저하를 최소화시키기 위해 색 분포 재배열을 이용한 색 분별력 향상 색역 사상 방법을 제안한다. 제안한 방법은 입력 영상의 색을 색 분포라는 3차원 배열로 구성한다. 색 분포의 최대치가 출력 장치 색역의 경계치보다 작다면 같은 색으로 사상을 한다. 반대로 크다면 색역 내부에 색역 외부의 색을 재배열하여 사상을 한다. 결과적으로 모니터에 나타난 영상을 색과 비슷하고 채도가 높은 색이 선형적으로 변하는 영역에서 색의 분별력이 높은 영상을 프린터로 재현할 수 있었다. When the same image is displayed in many different devices, the reproduced colors are not same due to the differences in the gamut between devices. Therefore, many gamut mapping method were proposed to solve this problem. In this paper, color discrimination enhancement gamut mapping method using color distribution rearrangement is proposed to reduce the unnecessary distortions by compression mapping and to minimize the decrease of color discrimination by clipping method. The proposed method constructs color distribution, the 3-dimension array of input image's colors. if the maximum of color distribution is within the boundary of printer gamut. the colors are mapped to the same colors. Otherwise, out-of-gamut colors are compressed into the printer gamut with minimum distortion. Consequently, the printer output image was highly consistent with the corresponding monitor image and had an enhanced color discrimination in region where high chroma varied linearly.

본 논문에서는, 전편 논문인 I부에서 제시한 파수영역에서의 역산란 방법을 사용한 비균일한 유전체 기둥의 직사각형 단면내의 주어진 유전율 분포를 재구성 하였다. 수치계산 결과 산란전계의 측정위치와 유전체 단면내의 유전율 분포에 거의 상관없이 사용파장에 비해 훨씬 작은 정도로 주어진 유전율 분포를 재구성 할 수 있음을 보였다. In this paper, the reconstruction of complex permittivity distribution on a rectangular cross section of inhomogeneous dielectric cylinders is performed by employing the spectral inverse scattering scheme presented in the part I of these companion papers. Numerical simulations provide the superresolution to the permitivity profiles nearly regardless of the measurement locations of the scattered field and the permittivity distributions on the cross section.

Researchers' performances have been evaluated by contributing to the academic journals officially, and academic journals expanded both quantitatively and qualitatively since academic societies, publishers, and universities has concentrated on publishing journals. Recently, access and usage of academic information was restricted due to commercialization strategies and sudden rising of prices, and against this situation, OA movement came out arguing that academic information should be open to everyone freely. This article studies the case of KOASAS which is based on DSpace, one of the typical institutional repositories, and intends to show up the necessity to construct repositories in institutions universities and suggest the method to make full use of repositories.

As future warfare becomes network-centric, war-game simulators require high interoperability between networked forces and dynamic reconfiguration in accordance with war events. In this paper, we propose an event-driven methodology to develop dynamic war-game simulations. Federates are developed by event-driven web services. The event-driven web services consistently sense war events and response them only if they are interested. By the sense-and-response mechanism and asynchronous event processing, we are able to save simulation time. An Anti-Surface-Warfare simulator is constructed to demonstrate the methodology and suggests that event-driven web services are efficient to model and simulate warfare where numerous events are generated from hardware systems and people dispersed on the network.

Objective : The aim of this study was to investigate the relationship between interpersonal problems, body dissatisfaction, and suicidal idea. Methods : Two hundred ninety-four participants filled out the self-reporting questionnaires : Body dissatisfaction was measured with Body Dysmorphic Disorder Examination-Self Report (BDDE-SR) ; Interpersonal problems was measured with Korean Inventory of Interpersonal Problem (KIIP) ; Suicidal Ideation Questionnaire (SIQ) was used to assess suicidal idea. A path analysis was conducted to identify the impact of interpersonal problems and body dissatisfaction on the suicidal ideas. Results : 'Socially inhibited (KIIP_C4)', 'overly-accommodating (KIIP_C6)', age, and gender had a direct effect on their body dissatisfaction, and those factors had a indirect effect on the suicidal ideas. Also, 'cold (KIIP_C3)' and body dissatisfaction had a direct effect on the suicidal ideas. Conclusions : These findings can help to identify how interpersonal problems and body dissatisfaction influence the suicidal ideas of people. It would be useful to consider and assess suicidal ideas in the patients with 'cold (KIIP_C3)', 'socially inhibited (KIIP_C4)', 'overly-accommodating (KIIP_C6)'.

Frey syndrome is a disease characterized by abnormal sweating, facial redness, and rare pain by stimulation of taste sense on the limited area dominated by the auriculotemporal nerve and great auricular nerve. Although the developmental mechanism and histopathologic cause of Frey syndrome are still being debated, the most reliable theory is based on injury of the parathympathetic nerve connected to the auriculotemporal nerve continuing to abnormal regeneration. The other theory is that the sweat glands develop an increased sensitivity after degeneration of sympathetic fibers. Therapy of Frey syndrome includes drugs, radiographic treatment, and surgical treatment; however, in most cases, treatment is not satisfactory. This is a case report on a 24-year-old male patient with Frey syndrome caused by the fracture reduction with retromandibular approach after multiple facial traumas and spontaneous healing without any special treatment.

Testing of analog(and mixed-signal) circuits has been a difficult task for test engineers and effective test techniques to solve these problems are required. This paper develops a new technique which increases fault detection and diagnosis rates for analog circuits by using extended MTSS (Modified Time Slot Specification) technique based on MTSS proposed by the author. High performance current sensors with digital outputs are used as core components for these techniques. A fault diagnosis structure with minimal hardware overhead in ATE is also described.

이재민,윤형완,Lee, Jae-Min,Yun, Hyeong-Wan 한국응급구조학회 2010 한국응급구조학회지 Vol.14 No.3

Purpose: The purpose of this study is to determine potential differences in pre-hospital cases of cardiac arrest and drug Intoxication between elderly group and non-elderly group on local emergency activity sites of rescue 119 team for those cases, so that it can provide useful reference materials for a system of corresponding emergency medical services. Methods: Patients with cardiac arrest and drug intoxication in the elderly and the non-elderly group were analyzed by analyzing the Ambulance Run Report for 3 years from January 2007 to December 2009. Results: According to analysis on potential differences between elderly and the non-elderly group, it was found that there was no significant difference between elderly cases (evacuated to hospital due to cardiac arrest and drug poisoning) and non-elderly cases in year of onset (p = .247), quarter of onset (p = .813), sex (p = .235), consciousness state (p = .126), place of onset (p = .215) and number of first aid services (applied to emergency cases) respectively, but there were significant differences between elderly cases and non-elderly cases in guardian availability (p = .042), time zone of onset (p = .050), distance from the site of onset (p = .278), type of onset (p = .000), number of first aid services depending on distance of evacuation (p = .008) and effectiveness of emergency care (p = .003) on statistical basis. Conclusion: It is important to establish a system of early emergency case reports for rational emergency case management with lower mortality; shorten distance from the site of onset at each time zone of onset in emergency cases; employ more emergency team members; facilitate firsthand / secondhand medical instructions for emergency teams in specialized emergency care depending on distance of evacuation for each kind of onset (elderly group vs. non-elderly group); and improve rate of resuscitated emergency cases by extending the scope of works for emergency medical technicians into wider applications, so that it will be possible to take timely and appropriate measures for emergency settings of ever-increasing aged population in near future.
