Microdisplays based on organic light-emitting diodes (OLEDs) have a small form factor, and this can be a great advantage when applied to augmented reality and virtual reality devices. In addition, a high-resolution microdisplay of 3000 ppi or more can be achieved when applying a white OLED structure and a color filter. However, low luminance is the weakness of an OLED-based microdisplay as compared with other microdisplay technologies. By applying a tandem structure consisting of two separate emission layers, the efficiency of the OLED device is increased, and higher luminance can be achieved. The efficiency and white spectrum of the OLED device are affected by the position of the emitting layer in the tandem structure and calculated via optical simulation. Each white OLED device with optimized efficiency is fabricated according to the position of the emitting layer, and red, green, and blue spectrum and efficiency are confirmed after passing through color filters. The optimized white OLED device with color filters reaches 97.8% of the National Television Standards Committee standard.

To monitor the world's oceans and understand the role of the oceans for climate change, an Array for Real-time Geostrophic Oceanography (ARGO) program has been carried out since year 2000. Autonomous profiling floats of about 820 are reporting the vertical temperature, salinity, and pressure profiles of the upper 2000 m underwater at regular time intervals. Meteorological Research Institute (METRI) of Korea Meteorological Administration (KMA) launched 45 floats at the East Sea and the western Pacific to understand characteristics of water properties and develop the global ocean observation system as a part of international cooperation project. In this study, we introduce ARGO program, METRI-ARGO and the features of APEX float itself and their data formats. We also describe the significant points to be considered for using ARGO data.

연구기록의 생산 및 관리는 연구 품질 확보를 위한 필수전제조건이다. 연구품질보증 시스템은 연구노트를 포함한 연구기록의 품질 요건 강화를 기반으로 하여 효과적으로 동작할 수 있다. 우리나라의 연구개발분야가 성장하고 전자연구노트 도입이 추진됨에 따라 연구의 품질보증을 위한 연구기록의 관리 방안 수립이 중요한 과제로 등장하고 있다. 이 연구의 목적은 우리나라 연구개발기관들이 연구품질을 확보하는 기반으로서 연구기록을 생산, 관리하는 과정에서의 현안을 확인하고 이에 대한 방안을 살펴보려는 것이다. 선행연구 분석을 통해 연구기록의 품질 특성을 정리하고 국내 연구기관의 연구기록 관리현황 및 현안을 살펴본 다음 GLP(Good Laboratory Practice)를 벤치마킹하여 연구기록의 관리 요건 강화를 위한 과제를 제언하고 있다.

The objective of this study was to use remotely sensed data, combined with in situ data, for the assessment of trophic state for Daecheong reservoir. Three Landsat TM(Thematic Mapper) imagery data were processed to portray trophic state conditions. The remotely sensed data and the measured data were obtained on 20 June 1995. Regression models have been developed between the chlorophyll-a concentration and reflectance which was converted to Landsat TM digital data. The regression model was determined based on the correlation coefficient which was higher than 0.7 and was applied to the entire study area to generate a distribution map of chlorophyll-a and trophic state. The equation, providing estimates of chlorophyll-a concentration, represented the year-to-year spatial variation of trophic zones in the reservoir. Satellite remote sensing data derived from Landsat TM had been successfully used for trophic slate mapping in Daecheong reservoir.

The inhibitory effects of methanol extracts of 135 medicinal herbs on diacylglycerol acyltransferase (DGAT) activity were investigated. DGAT was partially purified from rat liver. Eleven kinds of methanol extracts of medicinal herbs including Evodiae Fructus showed a mild inhibitory effect with the concentration of $125\;{\mu}g/ml$ (above 40% inhibition). Six kinds of methanol extracts including Ephedrae Herba exhibited a weak inhibition. Among them, three kinds of butanol extracts (Sophorae Radix, Arecae Semen, Caesalpiniae Lignum) and the chloroform extracts of Evodiae Fructus showed significant inhibitory activities (above 60% inhibition) at the same concentration.

PRAM (Phase Change Random Access Memory) is well known to use reversible phase transition between amorphous (high resistance) and crystalline (low resistance) states of chalcogenide thin film by electrical Joule heating. In this paper, we introduce a stack-type PRAM device with a novel GST/TiAlN structures (GST and a heating layer of TiAlN), and report its electrical switching properties. XRD analysis result of GST thin film indicates that the crystallization of the GST film start at about $200^{\circ}C$. Electrical property results such as I-V & R-V show that the phase change switching operation between set and reset states is observed, as various input electrical sources are applied.
