천연염색은 전통적으로 세계 여러 나라에서 사용되어 왔으며, 천연염색이 다양해짐에 따라 염색 패턴의 다양성도 확대되고 있다. 본 연구는 4가지 천연염료에 대한 염료와 매염제의 색상 변화를 보다 정확하게 분석하여 사물인터넷에 정량화된 정보를 제공할 수 있는 수치를 제공함으로써 표준화를 마련하고자 했다. Juglans regia Linn에서 추출한 염료에 구리 아세테이트, 철 II 황산염 및 중크롬산 칼륨을 첨가하면 갈색의 원래 색상이 각각 보라색, 카키색 및 암갈색의 다른 색상으로 변경되었다. Sophora japonica L. 또는 Phellodendron amurense Ruprecht에 첨가된 중크롬산 칼륨을 제외하고는 다른 매염제의 농도는 감소되었지만 염색된 실크의 색상 차이는 매우 컸다. 그러나 정도의 차이는 있지만 초산구리와 황산철은 각각 35%와 15%의 색변화를 유도하였다. 종합해볼때, J. regia Linn, S. japonica L.과 P. amurense Ruprecht에는 copper acetate 15 gram을 Phytolacca americana에는 150 gram의 iron이 정확히 첨가된 것이 가장 높은 색상변화를 유도할 수 있다고 확인되었다. 본 연구의 결과는 다양한 매염제에 의한 정확한 색상 변화가 염료 및 매염제에 의한 보다 정확한 색상 유도를 가능하게 하는 중요한 정보로 활용될 수 있음을 시사하였다. Natural dyeing has traditionally been used in many countries around the world, and as natural dyes are diversified, the diversity of dyeing patterns is also expanding. This study tried to establish standardization by providing numerical values that could provide quantified information to the Internet of Things by more accurately analyzing the color changes of dyes and mordants for the four natural dyes. The addition of copper acetate, iron II sulfate and potassium dichromate to the dye extracted from Juglans regia Linn changed the original color of brown to other colors of purple, khaki and dark brown, respectively. Except for potassium dichromate added to Sophora japonica L. or Phellodendron amurense Ruprecht, the concentration of other mordants was reduced, but the color difference of the dyed silk was very large. However, although there is a difference in degree, copper acetate and iron sulfate induced color changes of 35% and 15%, respectively. In summary, it was confirmed that the highest color change was induced when 15 grams of copper acetate was added to J. regia Linn, S. japonica L. and P. amurense Ruprecht and 150 grams of iron to Phytolacca americana. The results of this study suggested that the accurate color change by various mordants can be utilized as important information that enables more accurate color induction by dyes and mordants.

2007년에 천연 염료 관련 자원, 색상, 염색 원단 등 천연 염색 정보를 쉽게 제공 할 수 있도록 모바일 어플리케이션을 설계 한 것으로 알려졌다. 천연 염색과 IoT의 연관성, 응용 등에 대한 연구가 아직 부족한만큼 다양성 천연 염색에 의한 염색 패턴 변화에 관한 정보가 필요하다. 본 연구에서는, 천연 염료, 예를 들어 Lithospermum erythrorhizon가 한국에서 전통적으로 많이 사용되어온 실크에 대하여 염색 정보를 구축하고자 했다. L. erythrorhizon에서 염료의 추출은 pH4에서 수행되었다. L. erythrorhizon의 건조 된 뿌리는 짙은 갈색을 띤 자주색을 보였다. 매염제가 없는 실크 직물은 일반적으로 보라색 염색 패턴을 보였다. 타르타르산 나트륨과 구연산으로 염색 한 실크 직물은 투명한 갈색으로 염색되었다. 흥미롭게도 황산 철 (II)의 매염제 인 실크 직물은 검은 색이 아닌 밝은 회색으로 염색되었다. 알루미늄 포타슘 설페이트의 매염제를 L. erythrorhizon 추출 염료로 처리 한 결과 매염제를 처리하지 않았을 때와 거의 동일했다. 염색도를 수치로 평가 한 결과, 중크롬산 칼륨의 매염제의 처리는 약 50% 어둡고, 황산 철 (II)에 의한 염색은 약 75% 어두웠다. 이러한 결과는 L. erythrorhizon을 이용한 다양한 염색 색 적용 연구에 도움이되며, 염색 정도와 pH 농도, 색도변화라는 염색변수에 의한 염색 컨트롤러와 데이터베이스 시스템 구축에관한 정보를 제공 할 것이다. It was reported that a mobile application was designed to easily provide natural dyeing information such as natural dye related resources, colors and dyed fabrics in 2007. Since studies on the linkage, application, etc. between natural dye dyeing and IoT are still lacking, diversity of information on the change of dyeing pattern by natural dye dyeing is required. In this study, it was to construct dyeing information by natural dyes, e.g., Lithospermum erythrorhizon, on silk, which has been traditionally used as many fibers in Korea. The extraction of the dye from L. erythrorhizon was carried out under pH4. The dried root of L. erythrorhizon showed dark brownish purple. Silk fabric by a without a mordant typically showed a purple dyed pattern. In the staining by sodium tartrate plus citric acid, silk fabric was stained clear brown. Interestingly, the mordant of iron (II) sulfate, the silk fabric was dyed in a light gray color rather than black. When the mordant of aluminum potassium sulfate was treated with L. erythrorhizon-extracted dye, the results were almost the same as when the mordant was not treated. When the degree of dyeing was evaluated numerically, the treatment of the mordant of potassium dichromate was about 50% darker, and the dyeing by iron (II) sulfate was about 75% darker. These results will be helpful in the study of applying various dye colors using L. erythrorhizon, and it will provide information on dyeing controller and database system construction by dyeing parameters such as dyeing degree, pH concentration, and chromaticity change.

가시아메바는 환경속에서 널리 분포되어있는 단세포 원생동물이다. 가시아메바는 심각하며 때때로 치명적인 감염, 예를들어 아에바성 각막염, 육아종성 아메바성 수막뇌염을 유발한다. A. castellanii와 A. polyphaga는 아메바생 각막염을 유발하는데 최근에 콘택트렌즈 착용자들에게 빈번하게 발생한다. 한편 A. culbertsoni는 만성적인 수막뇌염을 유발하는데 면역이 저하된 환자에게서 특히 발생한다. 아직 감염에 대한 병원성이나 병태생리학적 분석은 잘 분석이 되어있지 않다. 본 연구에서는, 가시아메바를 진단하는 방법으로 많이 사용되어왔던 전형적인 분석법과 세포 및 분자진단학적 분석법이 어떻게 적용되어왔는지 설명되었다. 또한, 혈청학적 분석법이 특이적 항체를 바탕으로 간략히 소개되었다. Acanthamoeba are single-celled protozoan organisms that are widely distributed in the environment. Acanthamoeba can cause serious and sometime fetal infections, e.g., amoebic keratitis (AK), granulomatous amoebic encephalitis (GAE). A. castellanii and A. polyphaga cause the AK in contact-lens wearers and A. culbertsoni do cause the GAE which is processed with chronic infections in compromised patients. The infectious pathogenesis and pathophysiology are not yet well understood. In this study, with traditional methods to diagnose Acanthamoeba, how cellular and molecular diagnosis have been applied was described. Moreover, serological analysis was introduced with the application of specific antibodies.

Suk-Yul Jung(정석률) 한국엔터테인먼트산업학회 2015 한국엔터테인먼트산업학회논문지 Vol.9 No.3

웰빙은 개인 혹은 단체 예를 들어 사회적인, 경제적인, 심리학적인, 정신학적인 혹은 의학적인 상태를 일컷는 말이다. 질적상태가 우수한 웰빙은 어떤 의미에 있어서 개인이나 단체의 경험이 긍적적이지만 낮은수준은 부정적 요인과 관련이 있다. 웰빙은 사람들의 식습관을 제어하고 또한 사람들의 의식에 의해 조절될 수 있다. 이러한 관련성으로 식품에서 첨가되는 조미료 또한 가능성이 있을 수 있는데, 조미료는 허브와 그 자체로 조미료라 불리는 양념이며 음식맛을 풍부하게 하거나 더욱 맛이 나도록 하는 것으로 알려져 있다. 상업화된 조미료는 포유동물 세포에 어떠한 영향을 미치는지 분석될 필요성이 있다. 본 연구에서는, 좀 더 상세한 분석을 위하여 포유동물세포에 대한 세포독성이 분석되었다. 본 연구에 사용된 조미료는 맛보고, 다시다 및 맛선생이다. 조미료 처리를 위하여, 5 그램을 완전히 녹이고 여과한 다음 사용하였다. 맛선생과 맛보고는 표적세포에 대한 세포독성이 농도에 따라 증가됨을 보였다. 좀 더 희석, 즉, 10배로 희석한 다음 조미료를 처리한 결과 전반적으로 세포독성이 감소함을 알 수 있었다. 좀 더 상세한 분석이 더욱 더 많은 조미료를 이용하여 분석할 필요가 있으며 해로운 효과가 있는지 알기 위하여 좀 더 세포적인 면에서 수행되어야 함을 본 연구는 제시한다. Well-being is a general term for the condition of an individual or group, for example their social, economic, psychological, spiritual or medical state; high well-being means that, in some sense, the individual or group"s experience is positive, while low well-being is associated with negative happenings. Well-being controls people"s eating habits and also can be controlled by people"s consciousness. In terms of well-being and food, supplements for dish, e.g., seasonings, can be associated with high well-being. Seasonings include herbs and spices, which are themselves frequently referred to as "seasonings" and magnify a natural flavor of a food making it richer or more delicate. Commercialized seasonings need to be analyzed to affect mammalian cells. For more detailed analyses, this study was to analyze cytotoxicity to the mammalian cells. Matbogo, Dasida and Matseonsang were used in this analysis. For preparations of the seasonings, 5 gram was completely dissolved. Matseonsang and Matbogo decreased the living target cell according to decreasing ratio. To analyze the diluted solutions of the seasonings, cytotoxicity was performed and only living number of the target cell was calculated. Overall, the cytotoxic effect of diluted seasoning solutions was decreased. Further analyses would be done with commercialized more seasonings. And new and healthy seasonings should be developed and analyzed for their harm and effects.

Suk-Yul Jung(정석률) 한국엔터테인먼트산업학회 2013 한국엔터테인먼트산업학회논문지 Vol.7 No.3

PLA2G4A 유전자는 세포막 인지질을 가수분해하고 촉매제 역할을 하여 염증반응을 조절하는 지질성 세포호르몬인 아라키돈산을 분해한다. 혈액에 존재하는 C-반응성 단백질은 염증, 감염, 외상 및 조직 괴사 등에 의한 영향을 받을 수 있다. 본 연구에서는 Korean Association Resource(KARE)에서 나온 839명 성인 남성에서 PLA2G4A 유전자에 있는 19 SNPs와 혈액에 있는 C-반응성 단백질과의 연관성 분석을 실시하였다. 세 개의 SNPs(rs4651330, rs12720526 and rs16826049)가 C-반응성 단백질과 연관성이 상당히 높았다(p-values: 0.0015 ~ 0.025). 본 연구는 PLA2G4A 유전자가 미생물 감염과 관련될 수 있다는 중요한 추가적인 증거자료가 될 수 있을 것이다. 또한 본 연구는 감염 반응과 관련된 C-반응성 단백질의 유전적인 기초자료로 활용될 수 있을 것이다. The PLA2G4A catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid, which is lipid-based cellular hormones that regulate inflammatory response. The C-reactive protein in blood can be influenced by inflammation, infection, trauma and tissue necrosis etc. We performed the association analysis between the C-reactive protein level in blood and the 19 SNPs in the PLA2G4A gene in the Korean Association Resource (KARE) cohort (839eldermales). The 3 SNPs (rs4651330, rs12720526 and rs16826049) in the PLA2G4A gene showed a significant association with C-reactive protein (p-values:0.0015~0.025). This study provides additional evidence in support of the finding that the PLA2G4A gene maybe related to infection of microbes. This study may provide insight into the genetic basis of C-reactive protein related to reaction of infection.

가시아메바는 주로 콘택트렌즈 착용자에게 아메바성 각막염을 유발하는 원충이다. 본 연구에서는, 상품화된 콘택트렌즈 세척액을 이용하여, 가시아메바에 대한 세포독성을 분석하였다. 또한 표적세포로 사용한 결막상피세포에 대한 세포독성을 분석하였다. 10%의 Amo Total Care 1 세척액은 가시아메바의 형태에 많은 영향을 유발하지는 않았다. 렌즈 세척액의 퍼센트를 증가시켰을 때, 가시아메바의 수는 감소하였고 가시아메바의 형태가 변화되었다. 10%와 50%의 Opti-free RepleniSH 세척액은 Amo Total Care 1 세척액보다 좋은 효과를 보였다. 0에서 100 ul 렌즈 세척액은 HCEC에 대한 세포독성은 미약하였다. 가시아메바는 Amo Total Care 1에 의하여 40% 정도의 세포독성이 유발되었다. 한편, 가시아메바에 대하여 Opti-free RepleniSH는 약 38%에서 58% 까지 세포독성을 유발하였다. 본 결과를 종합해볼 때, 두 개의 세척액은 가시아메바에 대하여 좋은 효과를 가지지만 높은 효과를 보이지는 않았다. 따라서, 더 강력한 화합물 및 새로운 조성이 개발되어 가시아메바 예방 및 치료에 적용되어야 할 것이다. Acanthamoeba is a free-living protozoan pathogen which causes blinding amoebic keratitis (AK) to contact-lens users. In this study, using commercialized contact lens-clearing solutions, their cytotoxicity were analyzed against Acanthamoeba. Moreover, their effects to Acanthamoeba were compared with cytotoxicity to a human corneal epithelial cell (HCEC) as a target cell. Only 10% of the lens solution of Amo Total Care 1 didn"t significantly affect the morphology of A. castellanii . As the percent of the lens solution was increased, it decreased the number of A. castellanii and changed shapes of the amoebae. 10% and 50% of Opti-free RepleniSH decreased the number of A. castellanii more than Amo Total Care 1. 0 to 100 ul of lens solutions had little cytotoxicity to HCEC. A. castellanii was severely affected about 40% of cytotoxicity of Amo Total Care 1. On the other hand, Opti-free RepleniSH had about 38% to 58% cytotoxicity to A. castellanii Our results showed that two contact-lens clearing solutions didn"t have very strong effects to A. castellanii trophozoites. Therefore, it suggests that other compositions and compounds of stronger cytotoxicity should be developed for disinfections to A. castellanii .
