콘텐츠식별체계(UCI)를 활용한 캐릭터 온라인 유통거래 활성화 방안 연구
김시범(Kim, SiBum) 한국문화산업학회 2012 문화산업연구 Vol.12 No.1
This study proposes some suggestions to cultivate character business through online trading system which promotes characters registered under UCI (Universal Content Identifier) system. As character business is based on copyrights, it is important to control illegal online usage where unrecognized users can approach. UCI system could be one of the many ways to prevent illegal usage and to trace licensed products and characters online. This study includes the concept of UCI and several case studies of online trading system operated by public sectors as well as private sectors in domestic and overseas market. Based on case studies, this study suggests some ideas about utilizing UCI for operating character online trading system. This study will be helpful to set up the operating system of character online trading system using UCI. Some works will be meaningful to character creators and licensees who are using characters as well as all parties related to licensing business.

Polycomb-Mediated Gene Silencing in Arabidopsis thaliana
Kim, Dong-Hwan,Sung, Sibum Korean Society for Molecular and Cellular Biology 2014 Molecules and cells Vol.37 No.12
Polycomb group (PcG) proteins are conserved chromatin regulators involved in the control of key developmental programs in eukaryotes. They collectively provide the transcriptional memory unique to each cell identity by maintaining transcriptional states of developmental genes. PcG proteins form multi-protein complexes, known as Polycomb repressive complex 1 (PRC1) and Polycomb repressive complex 2 (PRC2). PRC1 and PRC2 contribute to the stable gene silencing in part through catalyzing covalent histone modifications. Components of PRC1 and PRC2 are well conserved from plants to animals. PcG-mediated gene silencing has been extensively investigated in efforts to understand molecular mechanisms underlying developmental programs in eukaryotes. Here, we describe our current knowledge on PcG-mediated gene repression which dictates developmental programs by dynamic layers of regulatory activities, with an emphasis given to the model plant Arabidopsis thaliana.

Plasma Damage Mechanism of Electron Beam Curing Process for Spin on Dielectrics
Sung Gyu Pyo,Sibum Kim IEEE 2013 IEEE electron device letters Vol.34 No.5
<P>This letter presents the plasma damage mechanism of electron beam curing process for spin on dielectrics. Device damage is studied using the antenna gate metal-oxide-semiconductor field-effect transistor (MOSFET) in terms of the threshold voltage variation as a function of electron beam conditions such as ambient and cathode voltage. Threshold voltages of nMOSFET are decreased by an electron beam curing process without antenna ratio dependency. The electron energy and interlayer dielectric thickness between active devices and metal layers largely affect the variation of threshold voltage. From the experimental results, it is concluded that device damage induced by an electron beam curing process is characterized as radiation damage rather than electron charging damage. For the damage free electron beam curing process, it is essential to control the penetration depth of high-energy electrons by adjusting the cathode voltage while considering the dielectric thickness over active devices.</P>

V2X 및 환경 센서 융합 기반 교차로 안전 시스템 알고리즘 개발
박만복(Manbok Park),이상현(Sanghyun Lee),전시범(Sibum Jun),기석철(Seokcheol Kee),김정범(Jungbeom Kim),기창돈(Changdon Kee),김규원(Kyuwon Kim),이경수(Kyongsu Yi) 한국자동차공학회 2014 한국 자동차공학회논문집 Vol.22 No.5
This paper describes the development and verification of control algorithms for V2X and environmental sensor integrated intersection support and safety systems. The objective of the research is to develop core technologies for effective fusion of V2X and environmental sensors and to develop new safety function for intersection safety. One of core technologies is to achieve the improvement of GPS accuracy, and the other is to develop the algorithm of a vehicle identification which matches all data from V2X, vehicle sensors and environmental sensors to specific vehicles. A intersection optimal pass (IOP) algorithm is designed based on these core technologies. IOP recommends appropriate speed to pass the intersection in the consideration of traffic light signal and preceeding vehicle existence. Another function is developed to prevent a collision avoidance when car crash caused by traffic violation of surrounding vehicles is expected. Finally all functions are implemented and tested in three test vehicles. It is shown that IOP can support convenient and comfortable driving with recommending optimal pass speed and collision avoidance algorithm can effectively prevent collision caused by traffic sign violation of surrounding vehicles.

Phosphorylation of CBP20 Links MicroRNA to Root Growth in the Ethylene Response
Zhang, Fan,wang, Likai,Lim, Jae Yun,Kim, Taewook,Pyo, Youngjae,Sung, Sibum,Shin, Chanseok,Qiao, Hong Public Library of Science 2016 PLoS genetics Vol.12 No.11
<▼1><P>Ethylene is one of the most important hormones for plant developmental processes and stress responses. However, the phosphorylation regulation in the ethylene signaling pathway is largely unknown. Here we report the phosphorylation of cap binding protein 20 (CBP20) at Ser<SUP>245</SUP> is regulated by ethylene, and the phosphorylation is involved in root growth. The constitutive phosphorylation mimic form of <I>CBP20</I> (<I>CBP20</I><SUP><I>S245E</I></SUP> or <I>CBP20</I><SUP><I>S245D</I></SUP>), while not the constitutive de-phosphorylation form of <I>CBP20</I> (<I>CBP20</I><SUP><I>S245A</I></SUP>) is able to rescue the root ethylene responsive phenotype of <I>cbp20</I>. By genome wide study with ethylene regulated gene expression and microRNA (miRNA) expression in the roots and shoots of both Col-0 and <I>cbp20</I>, we found miR319b is up regulated in roots while not in shoots, and its target <I>MYB33</I> is specifically down regulated in roots with ethylene treatment. We described both the phenotypic and molecular consequences of transgenic over-expression of <I>miR319b</I>. Increased levels of <I>miR319b</I> (<I>miR319bOE</I>) leads to enhanced ethylene responsive root phenotype and reduction of <I>MYB33</I> transcription level in roots; over expression of <I>MYB33</I>, which carrying mutated miR319b target site (<I>mMYB33</I>) in <I>miR319bOE</I> is able to recover both the root phenotype and the expression level of <I>MYB33</I>. Taken together, we proposed that ethylene regulated phosphorylation of CBP20 is involved in the root growth and one pathway is through the regulation of miR319b and its target <I>MYB33</I> in roots.</P></▼1><▼2><P><B>Author Summary</B></P><P>Ethylene is one of the most essential hormones for plant developmental processes and stress responses.
