林敬鎬,金炳三,金月洙,羅良基,鄭淳柱 전남대학교 농업과학기술연구소 2000 農業科學技術硏究 Vol.35 No.-

The effect of wounding method on rooting and field adaptation was studied in 'Sunaga Wase' peach and several cultivars in order to establish mass production system of rooted cutting. Rooting was more than 90% in 'Sunaga Wase', 'Kurakata wase', 'Wolbongjosaeng' and 'Wolmijosaeng', and Root number, weight and length showed similar tendency, however, taking root in field was the highest, as much as 75.8% 'in Sunaga Wase'. Modified wounding tool (MWT) was more effective than current method because rooted cutting with MWT showed high root growth including rooting, root number, root weight and saved wounding time.

본 연구는 퇴비원료로 지정된 제약업종 부산물(공정오니) 및 화장품 제조업 폐수처리오니를 퇴비로서 활용 가능성을 판단하기 위하여 기존의 일반성분이나 중금속 성분 분석 이외 유기성 화합물과 기타 여러 생물검정법 등을 활용하여 시용한 오니에 의한 토양 내 비료의 피해를 밝혀내고 이들의 평가방법을 확립하고자 포장시험을 수행하였다. 오니의 처리에 따른 HEM의 함량은 제약업종 오니2(PS2)와 화장품 오니(CS)처리가 각각 0.51, 1.10 mg/kg로 가장 높았고, PAHs의 함량은 제약업종 오니2(PS2) 처리에서 3,406.8 μg/kg로 가장 높았다. 토양에 서식하는 미소동물의 밀도변화는 생육 중기(7월 23일) 및 수확기(10월 1일) 모두 제약오니2 및 돈분 처리구에서 가장 높았으며, 기타 처리구는 차이가 없이 아주 낮았다. 오니의 처리에 따른 세균 및 사상균의 균수는 제약업종 오니2처리에서 각각 736, 909 cfu/g로 가장 많았고, 화장품 오니도 각각 440, 236 cfu/g으로 다른 처리에 비해 많은 경향을 보였다. 제약오니 및 화장품오니 처리시 우점세균은 무비, 돈분처리에 비해 일정한 경향이 없었으나 3요소 처리보다 다양한 세균이 검출되었다. 오니의 처리에 따른 우점사상균은 무처리에 비해 제약업종 오니3와 화장품 오니처리에서 형태적 특징이 다른 콜로니가 검출되었으나 다른 처리는 비슷한 경향으로 종류 간에 큰 차이는 보이지 않았다. Microcosm test를 통하여 오니 처리 후 3개월이 경과한 토양의 오염정도를 평가한 결과는 제약업종 오니3과 화장품 오니처리는 약간 영향을 받아서 80~90% 생존하였으나, 제약업종 오니1처리는 처리 2주(14일) 이후에는 급격히 생존율이 떨어져서 4주 이후에는 10%만 생존하였다. 그러나 6개월이 경과한 토양에서는 지렁이의 생존율은 제약업종 오니1처리만 약간 영향을 받은 것으로 보였으며 다른 처리들은 전혀 영향을 받지 않았던 것으로 조사되었다. 유기성 오니의 퇴비원료로 활용은 비료관리법의 비료공정 규격 중 퇴비의 비고란에 "퇴비의 원료로 사용 가능한 물질과 사용 불가능한 물질'(별표1)에서 "희비의 원료 중 사전 분석검토 후 사용 가능한 원료에 대한 지정요령'에는 유기물과 중금속(8성분) 함량(건물증)과 제조공정 등을 검토하여 지정하고 있으나, 지정된 원료가 과연 회비원료로 적합한지 잘 알 수 없으며 또한 앞으로 현재의 퇴비원료 규정을 변경할 필요가 있을 경우를 대비하여 희비원료의 적합성 여부를 판별할 수 있는 방법의 개발이 필요하다. 따라서 퇴비원료로 이미 지정('02. 12. 31)된 제약오니 및 화장품 오니를 과량으로 토양에 시용한 후 유해 유기화합물, 미소동물, 미생물 및 생물학적(지렁이) 유해성 검정방법의 도입 가능성을 평가하기 위하여 고추를 재배한 포장에서 비료의 피해시험을 실시한 결과 유해 유기화합물과 생물학적(지렁이) 유해성 검정방법은 앞으로 연구를 통해서 보완할 경우 상당히 활용 가능성이 있는 좋은 평가방법인 것으로 생각된다. This study was conducted to assessment organic compound and bioassay (density of inhabited animal, fluctuation of predominant fungi, and survival ratio of earthworm) for finding damage on red pepper by heavily amount application of sludges in soil, which was treated with 3 pharmaceutical byproducts and a cosmetic industry wastewater sludge as raw materials of compost, and for establishing estimation method. HEM contents in the soil treated with pharmaceutical byproducts sludge2 (PS2) and cosmetic sludge (CS) were 0.51, 1.10 mg/kg respectively. PAHs content of PS2 treatment in the soil was 3406.8 ug/kg on July 8. In abundance of soil faunas, the pharmaceutical byproducts sludge2 treatment was the most highest. The next was decreased in the order of pig manure (PM) and the cosmetic sludge treatment. However the other pharmaceutical sludge treatments were remarkably reduced populations of soil inhabited animals. In upland soil treated with organic sludges, the numbers of bacteria and fungi of the pharmaceutical sludge treatment were 736, 909 cfu/g and those of the cosmetic sludge treatment were 440, 236 cfu/g, respectively. The pharmaceutical sludge treatments and the cosmetic sludge treatment in identification of predominant bacteria were not any tendency to compare with non fertilizer and pig manure treatments, but they had diverse bacteria than NPK treatment. In microcosm tests, the survival of the tiger earthworm in five soil samples was hardly affected against the soil of PSI (20%) after three months treated in the upland. But after six months, survival of PSI was 80%. At present, raw material of compost was authorized by contents of organic matter, heavy metal (8 elements), and product processing according to "The specified gist on possible materials of using after analysis and investigation among raw materials of compost", however, for preparing to change regulation of raw material of compost and for considering to possibility of application, this study was conducted to investigate toxic organic compound and bioassay methods using inhabited animal, fungi, and earthworm without current regulation.

Device characteristics of inkjet-printed ZnO TFTs by solution process

Lim, Sang Chul,Koo, Jae Bon,Park, Chan Woo,Jung, Soon-Won,Na, Bock Soon,Lee, Sang Suk,Chu, Hye Yong IOP Publishing 2014 Japanese journal of applied physics Vol.53 No.5

<P>We report on solution-processed n-channel ZnO thin-film transistors. We fabricated by a low-temperature process to improve their performance using inkjet printing under various conditions. The resulting films were inkjet-printed with a resolution 200 dpi using droplets of 50 mu m diameter and 35 pl volume. The characteristics of the inkjet-printed TFTs were improved significantly at an annealing temperature of 150 degrees C. The field-effect mobility, Vth, and on/off current ratio were 3.03cm(2)V(-1) s(-1), -3.3V, and 10(6), respectively. These results indicate that annealing at 150 degrees C is sufficient to obtain a mobility (mu(sat)) as large as 3.03cm(2)V(-1) s(-1). (C) 2014 The Japan Society of Applied Physics</P>

Lim, Bogyu,Jo, Jang,Na, Seok-In,Kim, Juhwan,Kim, Seok-Soon,Kim, Dong-Yu The Royal Society of Chemistry 2010 Journal of materials chemistry Vol.20 No.48

<p>Controlling the morphology in bulk-heterojunction solar cells is the preferred and most effective way to achieve high efficiency. To control the morphology, we synthesized a novel hydrophobic end-functionalized <B>P3HT</B> to induce hydrophilic–hydrophobic repulsive interactions in the boundary between the relatively hydrophilic <B>PCBM</B> and the relatively hydrophobic <B>P3HT</B>. The introduction of hydrophobic end-functionalized <B>P3HT</B> (<B>F-P3HT</B>) leads to larger <B>PCBM</B> clusters, while maintaining the crystallinity of <B>P3HT</B> due to repulsive interactions. <B>F-P3HT</B> thus provides a maximized continuous interfacial area between the donor and the acceptor as well as bi-continuous networks of donor and acceptor domains, resulting in better percolation pathways for charge transport.</p> <P>Graphic Abstract</P><P>To control the morphology, we synthesized a hydrophobic end-functionalized <B>P3HT</B> (<B>F-P3HT</B>) to induce hydrophilic–hydrophobic repulsions interactions in the boundary between the relatively hydrophilic <B>PCBM</B> and the relatively hydrophobic <B>P3HT</B>. <B>F-P3HT</B> thus provides a maximized continuous interfacial area between the donor and the acceptor as well as bi-continuous networks of donor and acceptor domains, resulting in better percolation pathways for charge transport. <img src='http://pubs.rsc.org/ej/JM/2010/c0jm02296a/c0jm02296a-ga.gif'> </P>

Low k Materials for High Frequency High Integration Modules

Na, Yoon-Soo,Lim, Tae-Young,Kim, Jin-Ho,Shin, Hyo-Soon,Hwang, Jong-Hee,Cho, Yong-Soo The Korean Ceramic Society 2009 한국세라믹학회지 Vol.46 No.4

Glass systems based on Ca, Sr, Ba, and Zn modified alumino-boro silicates were investigated in order to improve the dielectric and mechanical properties of a typical LTCC (low temperature co-fired ceramic) which was developed for high frequency highly-integrated modules. The glass was prepared by a typical melting procedure and then mixed with cordierite fillers to fabricate glass/ceramic composite-type LTCC materials. The amount of cordierite filler was fixed at 50 volumetric%. For an optimal glass composition of 7.5% CaO, 7.5% BaO, 5% ZnO, 10% $Al_2O_3$, 30% $B_2O_3$, and 40% $SiO_2$ in mole ratio, the resultant LTCC composite showed a dielectric constant of 5.8 and a dielectric loss ($tan{\delta}$) of 0.0009 after firing at $900^{\circ}C$. An average bending strength of 160MPa was obtained for the optimal composition.
