RF DIN Connector의 Passive IMD 개선에 관한 연구

고윤선,정재필,오창헌,신동욱 한국항행학회 2002 韓國航行學會論文誌 Vol.6 No.3

최근 이동통신 서비스가 확대됨에 따라 인접 기지국간의 간섭문제가 증가하게 되었으며, 그에 따라 CDMA시스템의 active IMD 뿐만 아니라 PIMD (Passive Inter Modulation Distortion)에 대한 문제도 시스템 설계 시 고려되어야 한다. 본 논문에서는 RF connector 중 대표적 connector인 7/16“ DIN connector를 통하여 동촉선에서의 PIMD발생 정도를 분석하였고, PIME 개선 방안을 제안하였다. 첫째, 대부분의 전류가 통과하는 경로에는 표면조도가 좋은 금속이 전도율이 좋아 유리하며, 둘째 RF에너지가 충분ㅎ히 한 매질에서 통과할 수 있도록 최소 5m 이상으로 도금을 해야 함을 알수 있었다. 셋째, 도금 재료의 노화현상 방지를 위해 비열이 높고 전도율이 높은 금속 선택이 필수적이며, 비용절감 면에서는 삼원합금 등 대체 도금 재질 개발이 요구됨을 알 수 있었다. 현재 국내 PIMD 규격인 KTF-150dBc를 만족시키기 위해서는 7/16“ DIN connector 의 경우 도금재질에 관계없이 표면조도 6s, 도금두께 5m일때 KTF의 PIMD 규정을 만족시킬 수 있음을 알 수 있었다. Recently, as the range of mobile communication services is extended, the interference between adjacent base-stations is increased. Nowdays, on of the important factors causing interference is IMD(Inter-Modulation Distortion) problems. Not only active IMD but also passive IMD effects must be considered to design a CDMA system. In this study, we design and implement 7/16'' DIN connectors which have a various intensity of surface illumination, thickness and quality of plating material to analyze the effects of PIMD. And propose the methods for improving the PIMD characteristics: First, it is more profitable to use the metal which has good intensity of surface illumination where most of all electric currents passes through it. Secondly, we should plate metals more than 5 μm for RF energy enough to propagate in a medium. Thirdly, it is necessary to select a metal having high conductivity and specific heat to protect the aging phenomenon of plate material. And it is required to develop a new plating material to replace the current materials, such as the alloy of three components for cost reduction. We have to know that the plate which has intensity of surface illumination 6 S and the thickness of plating material 5 μm satisfy domestic PIMD specification (KTF) - 150 dBc, regardless of the plate material in case of 7/16'' DIN connector.

김보경,박국필,경희문,권오원,성재현 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.1

측방확대장치에 의한 정중구개봉합부의 확대시 고정력은 구개부의 신경요소들에 변화를 일으키면서 동통을 유발하게 되고 구개봉합부가 확대되고 그것이 유지되는 동안에 기계적 자극에 의한 구개부신경섬유의 반응성에 변화를 일으킬 것으로 생각된다. 본 연구에서는 백서 정중구개봉합부의 CGRP 면역반응 신경섬유의 교정력 적용시간에 따른 형태학적인 반응성, 밀도, 분포변화등을 관찰하고 그와 연관된 CGRP의 기능을 알아보고 자 250gm내외의 Sprague-Dawley 웅성백서 상악전치에 200gm의 치아이개력이 가해지도록 활성화시킨 helical spring을 삽입하여 정상대조군과 장치 장착후 경과시간에 따라 1일, 4일, 7일, 14일 경과군으로 나누어 정중구개봉합부를 확대후 희생시켜 면역조직화학법으로 염색하여 관찰하였다. · 대조군에서 정중구개 봉합붑 결합조직의 CGRP 면역양성 신경섬유는 거의 관찰되지 않았다. · 1일군에서는 대조군에 비해 CGRP 면역반응 신경섬유가 현저한 증가를 보였으며 주로 혈관 주위에 염주알 모양의 가는 신경섬유가 관찰되었다. · 4일군에서는 CGRP 면역반응 신경섬유가 대조군에 비해서는 현저한 증가를 보였으나 1일군에 비해서는 크게 증가하지 않았으며 혈관의 크기가 훨씬 확장되어 관찰되었다. · 7일군에서는 특징적으로 조골양세포가 새로이 형성된 골변연을 따라 줄지어 배열되는 독특한 양상이 관찰되었고 신경섬유의 수는 4일군에 비하여 감소하고 혈관의 직경도 감소되었다. · 14일군에서는 CGRP 면역반응 신경섬유가 7일군과 유사한 분포를 보였으며 확대에 의한 골변연의 불규칙성도 대체로 감소되었다. CGRP 면역반응 신경섬유는 정중구개봉합의 확대시 초기에 일어나는 신경원성 염증반응에 주로 관련되어 증식되는 것으로 생각된다. Midplatal suture expansion is often used for patients having narrow maxillary arch, cleft palate, respiratory handicap with narrow nasal cavity. CGRP has been known as a modulator of pain transmission in central nervous system and a local effector to peripheral tissue causing vasodilation, increase of blood flow, modulation of immune system, regulation of macrophagic function and stimulation of bone formation. To investigate changes of CGRP-immunoreactive nerve fibers in midpalatal suture during the the expansion, immunohistochemical study was performed by using rats. Experimental rats(10weeks, 250gm) were divided into five groups(control, 1, 4, 7, 14 days group (each n=4) and applied orthodontic force (approximately 200gm) to upper anterior incisors. Frozen sections of midpalatal suture area were immunostained by using rabbit antisera. The results were as follows. · The CGRP-immunoreactive nerve fibers were hardly observed in control group. · In 1 day group, the CGRP-immunoreactive nerve fibers were more increased around the vessels than control group. · In 4 days group, the CGRP-immunoreactive nerve fibers were more increased than control group, but not more increased than 1 day group. Vascular diameter was more enlarged. · In 7 days group, expecially, hematoxilin affinity of cells was remarkable and cells were arranged along the bone margin. The CGRP-immunoreactive nerve fibers were more reduced than 4 days group and vascular diameter was also reduced. · In 14 dayds group, the CGRP-immunoreactive nerve fibers were similar to those of 7 days group and the irregularity of bone margin was almost recoverd. In Conclusion, the CGRP-immunoreactive nerve fibers may be related to initial neurogenic inflammatory reaction in expanding mid-palatal suture.

석회시용에 의한 카드뮴의 부동화와 식물이용성 저감효과를 구명하기 위해 우리나라의 대표적인 석회비료인 소석회를 선정하여 소석회에 의한 논토양 내 카드뮴의 부동화 기작과 벼의 카드뮴 흡수특성을 조사하였다. 소석회는 토양의 pH와 음하전도를 증대시켜 카드뮴의 흡착을 증대시키는 것으로 조사되었다. 소석회의 처리량을 증가시킴에 따라 식물이 이용하기 쉬운 형태인 유효태 카드뮴과 치환성 및 carbonate 결합태 카드뮴의 함량이 유의적으로 감소하였다. 소석회를 8,000 mg/kg 과량으로 시용하였을 때 CdCO3 형태로의 침전이 가능하였을 것으로 판단되나 8,000 mg/kg 이하로 처리하였을 때 CdCO3나 Cd(OH)2 형태로의 침전은 없었던 것으로 조사되었다. 또한 토양의 pH와 음하전도는 유효태 카드뮴과치환성 및 carbonate 결합태 카드뮴의 함량과 유의한 부의상관관계를 나타내었다. 따라서 소석회에 의한 토양 내 카드뮴의 부동화는 CdCO3나 Cd(OH)2 형태로의 침전형성에 의한 것이 아니라 pH와 음하전도의 증대에 기인된 카드뮴 이온의 흡착에 의한 것으로 판단되어 졌다. 논토양의 현장조건에서 소석회의 시용에 의한 벼의 카드뮴 흡수농도 저감효과를 시험한 결과, 소석회의 시용량을 증가시킴에 따라 벼의 카드뮴 흡수농도는 유의적으로 감소하는 결과를 나타내었다. Research Article : BACKGROUND : Many studies associated with cadmium (Cd) immobilization using lime fertilizer have been conducted for several decades. However, these studies did not suggest exact mechanism of Cd immobilization using lime fertilizer and evaluated effect of lime fertilizer on Cd phytoavailability in rice paddy soil under field condition. METHODS AND RESULTS: This study was conducted to determine exact mechanism of Cd immobilization using lime fertilizer and evaluate liming effect on Cd uptake of rice in contaminated paddy soil. Ca(OH)2 was mixed with Cd contaminated arable soil at rates corresponding to 0, 1,000, 2,000, 4,000, and 8,000 mg/kg. The limed soil was moistened to paddy soil condition, and incubated at 25℃ for 4 weeks. NH4OAc extractable Cd concentration in soil decreased significantly with increasing Ca(OH)2 rate, since Ca(OH)2 markedly increased net negative charge of soil by pH increase, and decreased bioavailable Cd fractions (F1; exchangeable + acidic and reducible Cd fraction). Calculated solubility diagram indicated that Cd solubility was controlled by soil-Cd. NH4OAc extractable Cd and F1 concentration were negatively related to soil pH and negative charge. Ca(OH)2 was applied at rates 0, 2, 4, and 8 Mg/ha and then cultivated rice in the paddy soil under field condition. Cadmium concentrations in grain, straw, and root of rice plant decreased significantly with increasing application rate of Ca(OH)2. CONCLUSION(S): Alleviation of Cd phytoavailability with Ca(OH)2 can be attributed primarily to Cd immobilization due to the increase in soil pH and negative charge rather than precipitation of Cd(OH)2 or CdCO3, and therefore, Ca(OH)2 is effective for reducing Cd phytoavailability of rice in paddy soil.

( Jae Hong Oh ),( Hee Jae Park ),( Seung Pil Ham ),( Cheong Ha Woo ),( Mira Choi ),( Sik Haw ),( Hai-jin Park ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1

Hailey-Hailey disease (HHD) is a rare autosomal dominant disease characterized by crusted weeping erosions, vesiculopustules, and vegetating plaques with fissures. HHD affects the sites of friction such as the neckline, axilla, or groins. Itch, pain, and malodor are common complaints. HHD is exacerbated after triggers such as skin UV radiation, skin infection, physical trauma, excessive sweating. HHD may be difficult to distinguish from other intertriginous diseases. In particular, secondary bacterial or fungal infections are common on the affected areas, it is difficult to differentiate from infectious diseases such as erythrasma and candidiasis. A 50-year-old man presented with painful erythematous scaly patches with yellowish discharge on both thighs and scrotum for 7 months. As a driver, the patient was seated for a long time and his inguinal area was damped. Application of topical treatment showed mild effect, but it exacerbated because of tight clothing and his occupational status. Previously, he was diagnosed as erythrasma and treated with systemic and topical antibiotics, topical antifungals, and topical corticosteroids. Histopathologic examination on inguinal area showed suprabasilar clefting with acantholytic cells consistent with HHD. Direct immunofluorescence for IgG was negative. The patient was treated with oral minocycline. HHD should be considered in patients with recurrent flares of intertriginous lesions.
