본 연구에서는 새만금 담수호로 유입되는 유사량과 담수호의 장래퇴적분포를 추정하였다. GIS(Geographic Information System)와 범용토양유실량식(Universal Soil Loss Equation; USLE)을 적용하여 새만금 담수호 상류유역에서 발생하는 토양유실량을 산정하고, 총유실량-유사운송비(sediment delivery ratio) 법을 이용하여 담수호로 유입되는 유사량을 추정하였다. USLE에 의한 총 유실량은 2,804 천ton/yr, 새만금 소유역별 평균 유사운송비는 12%, 담수호 유입유사량은 328 천ton/yr으로 추정되었다. 새만금 담수호의 유효저수량과 유입량에 의한 포착효율(trap efficiency)을 고려하여 담수호에 실제 퇴적되는 양을 추정하고 새만금 담수호의 표고별 장래퇴적분포는 Lara method (USBR method)을 이용하였다. 새만금 담수호의 유사퇴적량은 302 천ton/yr으로 산정되었으며, Lara method에 의한 추정결과 5년, 10년 후 각각 새만금 담수호의 내용적이 0.4%, 0.7% 감소하는 것으로 나타났다.

E-Science Grid is designed to cope with computation-intensive tasks and to manage a huge volume of science data efficiently. However, certain tasks may involve more than one grid can offer in computation capability or incur a long wait time on other tasks. Resource sharing among Grids can solve this problem with proper processing-integrity check via audit. Due to their computing-intensive nature, the processing time of e-Science tasks tends to be long. This potential long wait before an audit failure encourages earlier audit mechanism during execution in order both to prevent resource waste and to detect any problem fast. In this paper, we propose a Light-weight, Adaptive and Reliable Audit, LARA, of processing Integrity for e-Science applications. With the LARA scheme. researchers can verify their processing earlier and fast.

The greenhouse is a complex system. It is subject to multiple input disturbances that are highly dependent on meteorological conditions, which are generally nonlinear and have a great influence on the agricultural production. The objective of this paper is to study the fuzzy logic technique as one of the most efficient technologies to control the greenhouse. The fuzzy logic controller (FLC) was developed to activate the actuator based on a ventilator was installed in an experimental greenhouse to obtain a desired temperature of the microclimate despite the externals disturbances.

In days to calyx-flex stage test, flower development affected by light intensity, light duration and the prevailing temperature. As, 'Jacaranda' variety shorter in under 46 days of flower bud formation and 13 days of calyx-flex stage than the other variety with 'Queen Elizabeth' control variety. About cut flower only 'Grand Vicki Brown' (as within 46 days of flower formation, 13 days of calyx stage and 'Jacaranda', both with shorter plants than the other varieties produced cut flower classified as short and medium-stemmed cut flowers. 'Jacaranda', 'Vicki Brown', 'Golden Times', 'Champagne', 'Osiana', and 'Queen Elizabeth (control variety)' flowered earlier from 46.7 to 50.8 days from pruning. Flower development was likewise faster in all the above mentioned cultivars; while 'Tineke' had significantly delayed flower development reaching calyx-flex stage from 0.5 cm bud size after 51.0 days. The top ten high yielding varieties were 'American Orange', with a net income of P3,081,676.00; 'Yellow Island' with P1,572,874.00; 'Frosty Pink' with P1,085,183.00; 'Champagne' with P980,620.00; 'Coral Pink' with P959,669.00; 'Lara Pink' with P918,444.00; 'Lara Orange' with P714,252.00; 'Grand Gala' with P705,787.00; 'Golden Times' with P806,489.00; and 'Lady X' with P778,060.00 net returns.

본 연구의 목적은 내장저수지의 장래 퇴적량 및 퇴적분포를 추정하는 것으로 연구 결과는 다음과 같다. 1) 내장저수지 유역의 장래 토양유실량을 추정하기 위해 Landsat-5 TM 1984년 영상과 2001년 영상을 분석하여 토지이용변화를 알아보고, 연간 토양유실량 변화를 추정하였다. 2) 내장저수지 유역의 토양유실량을 추정하기 위하여 범용토양유실공식(USLE, Universal Soil Loss Equation)을 이용하였으며, 담수호로 유입되는 양을 추정하기 위하여 유사운송비법을 사용하였다. 담수호로 유입된 유사량 중 퇴적되는 양을 추정하기 위하여 유사량-포착효율법을 이용하였다. 3) 토양유실량의 연평균증가율을 바탕으로 장래 유입 유사량 및 퇴적량을 예측하였으며, Lara법에 의한 수위-내용적 관계 및 표고별 퇴적분포를 추정하였다.

The aerobic growth and metabolic performance of Escherichia coli strains BL21 and W3110 were studied when the Vitreoscilla hemoglobin (VHb) was constitutively expressed in the chromosome. When VHb was expressed, acetate production decreased in both strains and was nearly eliminated in BL21. Transcriptional levels of the glyoxylate shunt genes decreased in both strains when VHb was expressed. However, higher transcription of the α-ketoglutarate dehydrogenase genes were observed for W3110, while for BL21 transcription levels decreased. VHb expression reduced the transcription of the cytochrome bo₃ genes only in BL21. These results are useful for better selecting a production host.

Both PM-OLEDs and AM-OLEDs are now in production. However, manufacturers are still concerned about life-time, voltage drift, operating voltage and efficiency in order to develop larger displays. Most material suppliers seem to be focussing on emitters and the benefits of introducing suitable charge transporters have been largely unexplored. OLED-T has developed a novel organic electron injector (Trade Name: EI-101) which evaporates at a very low temperature of $300^{\circ}C$ as opposed to the conventional LiF which requires $580^{\circ}C$. EI-101 has been found to increase the lifetime by up to 12%, reduce the voltage drift by up to 61% and increase the efficiency by up to 15%. The material can be handled in air and in situ Q-mass spectroscopy on extended thermal evaporation has confirmed its high stability for use in mass production.

This study presents a comprehensive solution to the collection management, which is based on the model for Cultural Objects (CCO). The developed system manages and spreads the collections that are safeguarded in museums and galleries more easily by using IT. In particular, we present our approach for a non-structured search and recovery of the objects based on the annotation of artwork images. In this methodology, we have introduced a faceted search used as a framework for multi-classification and for exploring/browsing complex information bases in a guided, yet unconstrained way, through a visual interface.

The present study was performed to assess the activity of the botulinum toxin A on breast cancer cells. The T47D cell line was exposed to diverse concentrations of the botulinum toxin A and cell viability and apoptosis were estimated using MTT and propidium iodine/annexin V methods, respectively. Botulinum toxin A exerted greater cytotoxic activity in T47D cells in comparison with MCF10A normal cells; this appeared to be via apoptotic processes caspase-3 and -7. In conclusion, botulinum toxin A induces caspase-3 and -7 dependent apoptotic processes in the T47D breast cancer cell line.

In this letter, we will evaluate the performance degradation of a 40 km high-speed (40 Gb/s) optical system, induced by optical fiber variations of the chromatic dispersion induced by temperature changes. The chromatic dispersion temperature sensitivity will be estimated based on the signal quality parameters.
