Zinc finger nucleases (ZFNs) have been used for targeted mutagenesis in eukaryotic cells. Custom-designed ZFNs can induce double-strand breaks (DSBs) at a specific locus. Our custom ZFN dimer was designed 3-finger of left and 4-finger of right with 2 kb size using 2A. A Ti-plasmid vector, pTA7002 containing the target site of SSS4A gene for a ZFN pair, that was shown to be active in yeast, was integrated in the rice genome. This promising technique for genome engineering was induced into 4 exon region of SSS4A gene in rice genome using Agrobacterium-mediated transformation. The SSS4A full-length cDNA was 5,070 bp consisting of a 318 bp 5′-untranslated region (UTR), a complete ORF of 2,928 bp encoding a polypeptide of 975 amino acids and a 3′-UTR of 1,824 bp. The vector is based on glucocorticoid receptor inducible gene expression system. Thus, SSS4A::ZFN expression was tightly controlled and the phenotype in low concentrations 10uM of the glucocorticoid hormone dexamethasone (DEX). In plant cells, transient ZFN expression is achieved by direct gene transfer into the target cells. For an alternative, ZFN delivery and production of mutant plants using a tobacco transient expression system for indirect transient delivery of ZFNs into a variety of tissues and cells of plants. ZFN activity was determined by PCR and sequence analysis of the target site. ZFN induced plants were obtained in up to 2% of the PCR products, consisting of deletions ranging between 1and 100 bp and insertions ranging between 1 and 10 bp. Our results describe an alternative to direct gene transfer for ZFN delivery and for the production of mutated rice.

As a custom is different according to ethnicity, even music is varied a singing method(唱法) and a technique(技巧) depending on a natural characteristic(風土). Sijo(時調, traditional three-verse Korean poem) is also divided into Gyeongje(京制) in Seoul·Gyeonggi, Naepoje(內浦制) in Chungcheong-do Province, Yeongje(嶺制) in Gyeongsang-do Province, and Wanje(完制) in Jeolla-do Province. Excluding Gyeongje(京制), all Je(制)s are commonly named Hyangje(鄕制) as a meaning of Jibangje(地方制). This study examined a transmission relation and a future task of Naepoje-sijo(內浦制時調) in Chungcheong-do Province, thereby having obtained the following conclusions. First, Naepoje-sijo(內浦制時調) was passed down as Wit-naepoje-sijo focusing on Seosan, as Araet-naepoje-sijo centering on Buyeo, and as Yeongdong-naepoje-sijo in Chungbuk. Second, the entertainers of intangible cultural properties were designated Soh Dong-gyu in 1992 for Araet-naepoje-sijo, Soh Dong-gyu in 2004 for Yeongdong-naepoje-sijo, and Park Seon-ung in 2014 for Wit-naepoje-sijo. Third, in terms of the current transmission for the year in 2020, Araet-naepoje-sijo is handed down by Kim Yeon-so(Buyeo). Wit-naepoje-sijo is passed down by Park Seon-ung(Seosan). Yeongdong-naepoje-sijo is uncertain in transmission following the demise of Han U-seop(Yeongdong). Fourth, Naepoje-sijo(內浦制時調) is urgent in music production, requires the characterization identification, and is demanded presentation and contest lesson. Also, Daejeon Metropolitan City and Sejong Autonomous City will need to designate Naepoje-sijo(內浦制時調) as an intangible cultural asset. Chungcheongbuk-do Province should arrange the pivot of transmission through designating a holder of entertainment that remains vacant.

After inducing obesity by feeding 42.5% high-fat diet for 5 weeks, each 10 Sprague-Dawley rats were randomly assigned to high-fat diet control (HFD) group and high-fat diet group containing 3% Sargassum confusum extract (HFDSC). Weight gain of HFD group (2.96±0.31 g/day) was significantly (p<0.05) higher as compared to that of normal diet (ND) group (2.19±0.17 g/day). Weights of adipose tissues of HFD group were higher than those of ND group. Body weight gain of HFDSC group, however, was 2.36±0.24 g/day, which was significantly (p<0.05) lower by 21% than that of HFD group. In addition, weights of epididymal and perirenal adipose tissues were lower by 15% and 16%, respectively, as compared to those of HFD group. Biochemical analyses showed that concentration of triglyceride, total cholesterol, and fatty acids were significantly (p<0.05) lower in HFDSC group. These results suggest that Sargassum confusum extract has a high potential as an anti-obesity material by reducing weight gain and obesity-related factors in serum.

강여정(Kang, Yeo Jung),유정석(Yu, Jung Suk) 한국지적학회 2014 한국지적학회지 Vol.30 No.2

본 연구는 부동산 증권화 시장의 안정성 확보를 위한 증권화 관련 법령과 감정평가분야 개선방안을 검토하였다. 부동산 증권화 관련 법률 검토결과 증권화의 각 단계별로 자산가치의 판정이 필요하며 증권화 과정에서 감정평가사가 부동산 시장 전문가로서의 역할을 수행할 수 있도록 제도적인 보완사항을 제시하였다. 또한, 국내에 비해 증권화 도입이 빠르면서 감정평가 제도가 유사한 일본의 증권화 시장과 감정평가 규정의 변화 과정을 검토 후 증권화 목적의 감정평가가 신뢰성과 객관성을 확보하기 위해서는 구체적인 감정평가기준이 필요함을 제안하였다. 감정평가기준의 내용에는 감정평가 결과가 다수의 이해관계인에게 영향을 미칠 수 있음을 감정평가 담당자가 인식하여야 한다는 윤리규정, 감정평가 방법은 할인현금흐름분석법이 원칙이어야 한다는 내용, 수익과 비용 항목 판단의 일관성을 위해 일본과 같이 항목에 대한 세부 정의 규정을 두어야 한다. 본 연구의 경우 재무적 관점에 초점을 맞춰 진행된 기존 연구와 달리 증권화 대상물인 부동산의 가치평가 관점에서 증권화 시장의 발전을 모색하였다는 점에서 의미가 있다. This research examines laws and ordinances to improve appraisal standards of real estate securitization. The examination of major laws related with real estate securitization proves that it is necessary to appraise asset values per stage of securitization. Since there are not enough institutional opportunities for appraiser to play the role of specialist of real estate market, related laws and ordinances need to be compensated for. We also investigate Japan's securitization market and changing process of rules on appraisers. Appraisal standards should include 1) ethics code, 2) discounted cash flow analysis, and 3) the consistency of income and expenditure item judgement as the case of Japan. Most of all, this paper contributes to developing securitization market in view of valuation of real estate unlike existing papers mainly rely on financial perspective.

In-depth considerations for better polyelectrolytes as interfacial materials in polymer solar cells

Yeo, Jun-Seok,Kang, Minji,Jung, Yen-Sook,Kang, Rira,Lee, Seung-Hoon,Heo, Youn-Jung,Jin, Sung-Ho,Kim, Dong-Yu,Na, Seok-In Elsevier 2016 Nano energy Vol.21 No.-

<P><B>Abstract</B></P> <P>We perform a comprehensive study to achieve better polyelectrolytes (PEs) as electron-transport layers (ETLs) in polymer solar cells (PSCs). Three well-known PEs – PFN, PEIE, and WPF – are chosen as model systems and investigated with variations in their backbone structures and the state of the amine functionalities on their side chains. Respectively optimized PSCs using the three PEs exhibit different cell-performances, mainly owing to the diode characteristics of built-in potential and recombination strength. To identify how such deviated device-performances correlate with the structural features of PEs, the modulated interfaces of ITO/PEs and PEs/active layer are studied in detail. It is found that conjugated backbones and larger counter-anions on side chains can promote the modulation of ITO work functions (WFs) and that a large amount of protonated amines on PEs is beneficial for junction properties with a subsequent active layer. Additionally, our results indicate that interfacial dipole and electrical doping between the PE and active layer, in addition to WF modulation of the ITO cathode, are important for device efficiency. Accordingly, with the aid of the molecular features of PEIE, PEIE-PSCs exhibit excellent device efficiency and stability compared with PFN- and WPF-PSCs. In the PTB7-th:PC<SUB>71</SUB>BM system, a remarkable power-conversion efficiency of 9.97% is achieved with a single PEIE ETL.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Chemical structure and performance of polyelectrolytes (PEs) in PSCs are correlated. </LI> <LI> Interfacial dipole and doping between PEs and active layer lead to efficient PSCs. </LI> <LI> PEIE-based PSCs have excellent device efficiency and high stability. </LI> <LI> Especially, in the PTB7-th system, encouraging efficiency of 9.97% is achieved. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Selective Morphology Control of Bulk Heterojunction in Polymer Solar Cells Using Binary Processing Additives

Jung, Yen-Sook,Yeo, Jun-Seok,Kim, Nam-Koo,Lee, Sehyun,Kim, Dong-Yu American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.44

<P>We report the effect of binary additives on the fabrication of polymer solar cells (PSCs) based on a bulk heterojunction (BHJ) system. The combination of 1,8-diiodooctane (DIO), a high-boiling and selective solvent, for fullerene derivatives and poly(dimethylsiloxane) (PDMS) precursor, a nonvolatile insulating additive, affords complementary functions on the effective modulation of BHJ morphology. It was found that DIO and PDMS precursor each play different roles in the control of BHJ morphology, and thus, the power conversion efficiency (PCE) can be further enhanced to 7.6% by improving the fill factor (FF) from 6.8% compared to that achieved using a conventional device employing only a DIO additive. In the BHJ of the active layer, DIO suppressed the large phase separation of PBDTTT-CF and. PC71BM while allowing the formation of continuous polymer networks in the donor polymer through phase separation of the PDMS precursor and BHJ components. The appropriate amount of PDMS precursor does not disturb charge transport in the BHJ despite having insulating properties. In addition, the dependence of photovoltaic parameters on different light intensities reveals that the charge recombination in the device with DIO and PDMS precursor decreases compared to that achieved using the device with only DIO.</P>

Case Report : A Case of Pigmented Bowen`s Disease

Jung Woo Lee,Jae Hur,Kwang Yeoll Yeo,Hee Joon Yu,Joung Soo Kim 대한피부과학회 2009 Annals of Dermatology Vol.21 No.2

Pigmented Bowen`s disease is characterized by increased melanin pigment in the epidermis or papillary dermis, in addition to the typical findings of Bowen`s disease. This disorder has been infrequently reported and it represents less than 2% of all cases of Bowen`s disease. Thus far, there has been only 1 case of pigmented Bowen`s disease on the umbilicus in the medical literature, and no such case has been reported in Korea. Pigmented Bowen`s disease develops on sun-exposed areas of the face and neck, as well as sun-un-exposed areas like the trunk, extremities, perianal area and umbilcus. A 36-year-old man presented with a 9-month history of solitary dark brown slithery or wavy plaque with a verrucous surface on the umbilicus, and the lesion measured 1x2 cm in size. The histopathologic findings showed hyperkeratosis, parakeratosis and atypical keratinocytes disorderly arranged throughout the epidermis. Increased melanin pigment was noted in the basal layer of the epidermis. From these findings, we diagnosed this lesion as pigmented Bowen`s disease. (Ann Dermatol 21(2) 197~199, 2009)
