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.

확공형 마이크로 파일의 지지력 해석

이재민,김두환,Lee,Jae-Min,Kim,Doo-Hwan 한국방재학회 2014 한국방재학회논문집 Vol.14 No.4

기존 마이크로 파일의 경우 전조나사 강봉과 그라우트와의 부착력 및 그라우트와 지반과의 주면마찰력에 의해 내하성능이 결정된다. 그러나 강봉과 그라우트 간의 부착성능이 가지는 취성파괴 특성과 낮은 내하성능에 의해 천공 깊이가 깊어지는 문제점을 갖고 있다. 따라서 본 연구에서는 기존 마이크로 파일의 지지성능을 개선하고 경제성을 향상시키기 위하여 perfobond rib를 구비한 강봉과 그라우트와 지반간의 주면마찰력을 증가시키기 위해 부분확공부를 설치하는 마이크로 파일을 제안하고, 거동 및 파괴특성에 대한 평가를 수행하였다. 현장 인발시험 결과 부분 확공하여 시공된 지반부 전단키에 의한 내하성능은 상당히 증가된 것으로 평가되었다. The load-carrying capacity of a conventional micropile is determined by the adhesion between the rolled screw thread and the grout, and the skin friction force between the grout and the ground. One of the disadvantage of the conventional micropiles is that the boring depth can be deeper because of low load-carrying capacity and the brittle failure behavior between rolled screw thread and grout. Therefore, it is necessary to develop an advanced feature of a micropile system which efficiently increases load-carrying capacity with a reasonable cost. This study proposes an advanced type of a micropile system. The proposed micropile system consists of perfobond ribs installed steel rod to improve shear capacity between the thread and the grout, and partially expanded drill holes to increase resistance capacity between the grout and the ground. Through on-site pullout tests, it was found that load-carrying capacity increased significantly in the proposed micropile system, due to the shear keys created by the partially expanded drill hole. The proposed micropile system was also evaluated to be much more economical in a case study.

Ham, sausage and bacon were treated with common household processing techniques including refrigerated storage(0, 14, 28 days) and cooking(pan-frying, microwaving, boiling). Lipid oxidation was evaluated by measuring fatty acid composition, malonaldehyde(MA), TBA values and by measuring fluorescent products. Major fatty acid composition were oleic acid and followed respectively palmitic acid, stearic acid, linoleic acid, linolinic acid. There was no significant difference in fatty acid composition by cooking method but there was a tendency of being increased of unsaturated fatty acid during 28days storage. Ma, TBA and fluorescent products showd a tendency of being increased continually according to storage days rather than cooking method.

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.

서울 시내 궁궐 수원의 수질과 유동 특성

이재민,우남칠,김연태,이강진,Lee, Jae-Min,Woo, Nam-C.,Kim, Youn-Tae,Lee, Kang-Jin 한국지하수토양환경학회 2011 지하수토양환경 Vol.16 No.2

This study was objected to provide suggestions for best management practices to restore the cultural and historical values of the wells in Palaces as well as their water qualities. Water resources in the five Palaces in Seoul Metropolitan, including Gyeongbokgung, Changdeokgung, Changgyeonggung, Jongmyo Shrine, and Deoksugung, were surveyed for their physical flows and chemical compositions from April to July in 2010. Ground waters in most wells were found at depths within 5 m from the ground surface, showing typical water-table aquifer systems. Hydraulic gradients indicate water resources in Gyeongbokgung, Changdeokgung, and Changgyeonggung flowing toward south, and toward east in Deoksugung area. Especially, water-level fluctuation data at S-10 in Deoksugung implied the influence of groundwater discharge facility. In Jongmyo Shrine, water was not detected in wells, indicating the water level was lower than the well depth. Based on the water chemistry and stable isotope analyses, water resources and their qualities appeared to be formed by the water-rock interaction along the groundwater paths. S-10 (Deoksugung) and S-14 (Changgyeonggung) samples were contaminated with nitrate ($NO_3$) in levels of higher than Korean drinking water standard, 10 mg/L as $NO_3$-N, but once in four sampling campaigns. In the situation that water resources in Palaces still maintain natural characteristics, the materials that will be used for the restoration and improvement of the Palace water supplies should be carefully selected not to disturb the natural integrity. In addition, because the wells are located in the center of metropolitan area, a systematic monitoring should be applied to detect and to manage the potential impacts of underground construction and various pollution sources.

As a preliminary survey to improve efficiency of well-based permeable reactive barrier system for groundwater remediation, this site-scale study was carried to identify the flowpaths and controlling factors of plume at a remediation site in Suwon City, Korea. A total of 22 monitoring wells were installed as a grid system in the $4m{\times}4m$ square area by 1-m interval. For the groundwater characterization, various tests were performed including water-level monitoring, water sampling & analysis, pumping and slug tests, and tracer tests. The aquifer appeared to be unconfined with hydraulic conductivities (K) ranging from $2.6{\times}10^{-4}cm/s$ to $9.5{\times}10^{-3}cm/s$. The average linear velocity of groundwater was estimated to be $2.94{\times}10^{-6}m/s$, and the longitudinal dispersivity of a conservative tracer to be $5.94{\times}10^{-7}m^2/s$. Groundwater plume moves preferentially through the high-K zones, and the relatively high ion concentrations along the low-K zones implying deterred groundwater flow. Consequently, the spatial variation of hydraulic conductivity caused by aquifer heterogeneity and anisotropy appears to be the most important factor to maximize the effect of plume treatment system for application of in-situ groundwater remediation techniques.
