The R&D budget of energy technology development has increased in the sector of Korean energy technology development continuously. In addition to that, KIER, the government invested research institute and unique energy technology R&D research institute, is trying to plan for a big-sized energy R&D program for the well focused R&D and excellent research outcomes. In the phase of R&D process, the planning is one of the most important sectors because it drives the direction of R&D. In this study, we suggest the assessment criteria to select a strategic energy technology R&D programs by the analytic hierarchy process, which is one of multi-criteria decision making method (MCDM). We structure 2 tiers of hierarchy for assessing a big-sized R&D program and also establish 6 criteria in the level 1, which are energy environment, economic spin-off, technical spin-off, marketability, KIER mission, and cost. We allocate the relative weights of criteria by checking the values of consistency ratio as making pairwise comparisons. The result of this research will provide the decision makers as they select a right well focused R&D program.

The largest and oldest science and technology park in Korea, Daedeok Innopolis has 29 government research institutes and 5 universities. Every year these research organizations of Daedeok Innopolis are generating more than 7 thousands technology patents and the government tries to commercialize technologies through simple technology licensing to private companies. To facilitate the technology transfer, the new mechanism named research institute spin-offs has been exclusively granted to Daedeok Innopolis in 2006. Since then, the Innopolis Foundation has put lots of effort to activate the mechanism in order to create more commercialization of R&D results from government research institutes (GRIs). This study is undertaken to review the interactive environment of the technology transfer in Daedeok Innopolis and study the unique mechanism which enables Daedeok Innopolis to proceed technology transfer effectively and in particular, looks at the role which can be played by the Innopolis Foundation as a government agent of the policy aimed at facilitating commercialization of using technologies developed by GRIs.

Conventional lithography methods of gold patterning are based on deposition and lift-off or deposition and etching. In this letter, we demonstrate a novel method of gold patterning using spin-coatable gold electron-beam resist which is functionalized gold nanocrystals with amine ligands. Amine-stabilized gold electron beam resist exhibits good sensitivity, 3.0 mC/$cm^2$, compared to that of thiol-stabilized gold electron beam resists. The proposed method reduces the number of processing steps and provides greater freedom in the patterning of complex nanostructures.

In this paper, we investigated the effect of solvent on electrical properties of triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs). The TIPS pentacene was spin coated by using chlorobenzene, p-xylene, chloroform and toluene as solvent. Fabricated OTFT with chlorobenzene showed field-effect mobility of $0.01\;cm^2/V{\cdot}s$, on/off ratio $4.3{\times}10^3$ and threshold voltage of 5.5 V. In contrast, with chloroform the mobility was $5.8{\times}10^{-7}\;cm^2/Vs$, on/off ratio $1.1{\times}10^2$ and threshold voltage of 1.7 V.

미국의 클린턴 행정부는 풍부한 영상 소프트웨어, 정보통신기술에서의 우위성, 고도의 네트워크를 바탕으로 21세기 정보사회에서의 주도권을 확보하기 위하여 노력하고 있다. 특히 냉전체제의 종식으로 인하여 국방분야에서의 여력이 생긴 연구개발 자원을 민생기술중심으로 전환하고 있으며, 국방분야에서 축적된 기술을 민간으로 확산하는 Spin-off 패러다임이 비판을 받으면서 Spin-on 패러다임을 동시에 구사하는 Dual-use전략을 사용하고 있다. 특히 NII구축을 통하여 다음 세기에서의 국가경쟁력을 강화하고, 국민의 삶을 질을 높이기 위한 노력을 선두적으로 추구하고 있는 상황임을 감안할 때, 미국에서의 정보통신기술정책 및 전략방향을 살펴보는 것은 초고속 기반구축사업을 추진하고 있는 우리 실정에 시사되는 바가 크리라 판단된다. 이를 위해서 미국의 정보통신기술 개발체계와 HPCC(High Performance Cumputing and Communications) 프로그램의 기술개발 현황을 중심으로 정보통신기술개발 동향을 분석하고 정보통신기술에 대한 장기적인 연구개발 방향을 분석하고자 한다.

The buffer layer was spin-coated on the dielectric layer of OTFTs to introduce the hydrophobicity for enhancing the device performance. this functional layer contains the water-proof ingredient to reduce the surface energy and more importantly, does not harm the dielectric property of the dielectric layer. With the help of proposed hydrophobic layer, the transistor showed dramatic improvement at electrical performance which was almost 20 times higher mobility compared to the non-treated case. And on/off ratio was also guaranteed as $10^{5{\sim}6}$.

We report the fabrication of organic field-effect transistors (OFETs) via spray coating of electrochemically exfoliated graphene (EEG) and conducting polymer hybrid as electrodes. To reduce the roughness and sheet resistance of the EEG electrodes, subsequent coating of conducting polymer (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS)) and acid treatment was performed. After that, active channel layer was developed by spin coating of semiconducting poly(3-hexylthiophene) on the hybrid electrodes to define the bottom gate bottom contact configuration. The OFET devices with the EEG/PEDOT:PSS hybrid electrodes showed a reasonable electrical performances (field effect mobility = $0.15cm^2V^{-1}\;s^{-1}$, on/off current ratio = $10^2$, and threshold voltage = -1.57V). Furthermore, the flexible OFET devices based on the Polydimethlsiloxane (PDMS) substrate and ion gel dielectric layer exhibited higher electrical performances (field effect mobility = $6.32cm^2V^{-1}\;s^{-1}$, on/off current ratio = $10^3$, and threshold voltage = -1.06V) and excellent electrical stability until 1000 cycles of bending test, which means that the hybrid electrode is applicable to various organic electronic devices, such as flexible OFETs, supercapacitors, organic sensors, and actuators.

Korea Microlensing Telescope Network (KMTNet) is the first optical survey system of its kind in a way that three KMTNet observatories are longitudinally well-separated, and thus have the benefit of 24-hour continuous monitoring of the southern sky. The wide-field and round-the-clock operation capabilities of this network facility are ideal for survey and the physical characterization of small Solar System bodies. We obtain their orbits, absolute magnitudes (H), three dimensional shape models, spin periods and spin states, activity levels based on the time-series broadband photometry. Their approximate surface mineralogy is also identified using colors and band slopes. The automated observation scheduler, the data pipeline, the dedicated computing facility, related research activity and the team members are collectively called 'DEEP-South' (DEep Ecliptic Patrol of Southern sky). DEEP-South observation is being made during the off-season for exoplanet search, yet part of the telescope time is shared in the period between when the Galactic bulge rises early in the morning and sets early in the evening. We present here the observation mode, strategy, software, test runs, early results, and the future plan of DEEP-South.

In this paper, we demonstrate that the organic electrophosphorescent device is driven by the organic thin film transistor with spin-coated photoacryl gate insulator. It was found that electrical output characteristics in our organic thin film transistors using the staggered-inverted top-contact structure showed the non-saturated slope in the saturation region and the sub-threshold nonlinearity in the triode region, where we obtained the maximum power luminance that was about 90 $cd/m^2$. Field effect mobility, threshold voltage, and on-off current ratio in 0.45 ${\mu}m$ thick gate dielectric layer were 0.17 $cm^2/Vs$, -7 V, and $10^6$ , respectively. In order to form polyimide as a gate insulator, vapor deposition polymerization process was also introduced instead of spin-coating process, where polyimide film was co-deposited by high-vacuum thermal evaporation from 4,4'-oxydiphthalic anhydride (ODPA) and 4,4'-oxydianiline (ODA) and cured at 150${\sqsubset}$for 1hr. It was also found that field effect mobility, threshold voltage, on-off current ratio, and sub-threshold slope with 0.45 ${\mu}m$ thick gate dielectric films were 0.134 $cm^2/Vs$, -7 V, and $10^6$ A/A, and 1 V/decade, respectively.
