The easily use of WWW and Web browser of INTERNET makes the world our stage. But when we search for the information and resource that we want, the information supplied by search engine (e.g., Yahoo, Lycos, WebCrawler, Alta Vista) is inadequate to acquire the necessary and related information of research issues. This paper surveys AMT(Advanced Manufacturing Technology) which is the research topics recently on the WWW(WorLd Wide Web) and provides searching methods and information for academic research, technical report, proceedings, software, etc. It also briefly surveys WWW-VL(Virtual Library) and reviews the major three technology, CALS (Commerce At Light Speed), AMS(Agile Manufacturing System), CE(Concurrent Engineering), that is recently the focus of the research issue of Industrial Engineer.

The Vista Variable in the Via Lactea(VVV)는 European Southern Observatory(ESO) Public Survey 중 하나로 Near-IR에서 (주로 K-band)에서 관측되며 1929시간에 걸쳐 은하 중심부의 더 깊은 영역에 대한 관측을 수행할 것이다. VVV Survey를 통해 520 sq. deg에 걸친 영역에서 33개의 잘 알려진 구상성단과 350개의 산개성단을 포함한 ~109개의 별에 대한 광도 곡선을 얻을 수 있을 것으로 예상되며 이들을 분류하기 위해 자동화된 분류 체계가 필요할 것이다. 본 연구는 VVV Survey의 일환으로 보현산 천문대의 근적외선 카메라시스템 KASINICS를 이용하여 Cataclysmic Variable stars에 대한 관측을 시행하고 있다. Cataclysmic Variable stars는 초신성 폭발이나 쌍성계 중 한 쪽 별에서 다른 쪽 별로 대기가 유입되었는 경우 등에 의해 광도가 급격히 증가하는 천체로 아직 많이 연구되지 않은 적외선 파장대로 관측함으로써 적외선영역에서의 물리적 특성에 대한 분석을 하고자 한다. 본 발표에서는 보현산 천문대의 근적외선카메라시스템 KASINICS에서 관측한 결과의 일부를 소개하고자 한다.

This study aimed at providing suggestions in designing open space so that parks and bordering facilities are well related to each other in terms of the visual access and human activities. The design survey was conducted in the center of Osaka City, using parks there as the study material. The relation between parks and their bordering facilities was evaluated in terms of the visual access and human activities. Through the results of this study, as the design methods for improving relations between parks and their bordering facilities, unified design and creation of square in the boundary area between them, placing access paths to facilities in parks, and planting trees to create Vista, Screen, and Framework landscapes are of great importance.

배터리로 동작하는 휴대용 기기와 같은 임베디드 시스템은 복잡한 애플리케이션을 보다 오랜 시간 동안 동작할 수 있도록 하기 위해 하드웨어와 소프트웨어 측면 모두에서 저전력 기법의 구성이 필요하다. 한정된 하드웨어 시스템의 자원을 효율적으로 관리하고 보다 적은 전력소모를 위해서는 저전력 기법이 탑재된 저전력 실시간 운영체제가 필요하다. 본 논문에서는 IBM 과 MontaVista Software 에서 제안한 DPM(Dynamic Power Management) 기법을 적용한 저전력 실시간 운영체제를 설계 및 구현하였다.

We study the overdensity of near-infrared sources around 508 sub-mm sources classified as dusty galaxies in the SPT-SZ survey catalog observed in 95 GHz (3.15 mm), 150 GHz (2 mm) and 250 GHz (1.2 mm) bands. We used the VISTA hemisphere survey data release 6 (VHS DR6) catalog covering the J, H, Ks bands. The mean number of galaxies within a radius of 60 arcsec (corresponding to about 500 kpc at z=2) from 500 randomly selected positions is 14.4, while the galaxy number distribution is approximated as a Gaussian with a standard deviation of 7.9. From the 2500 deg2 of SPT-SZ survey + VHS DR6 data, there were 27 sub-mm sources that have galaxy overdensity higher than 4σ. We present color-magnitude diagram around 27 selected sub-mm sources with enhanced galaxy surface densities, in order to investigate the presence of structure around sub-mm sources.

In this paper, we set up a vista point overlooking the focus of new research center placed on the existing research literature and point to the selection of books, reports or studies actually suggested focusing on topics such as for landscape simulation evaluation. To re-organize and classify a number of items were presented to spill the evaluation items of this view point selection via the SPSS Statistics. Evaluation items 16 through a professional survey to establish a concrete and systematic plan with selected research results leaked technical characteristics of the view that detailed questions to the factors of technical characteristics and population-specific comparisons through factor analysis in the first, landscapes simulation The views were set out. Second, if you set 16 classified by type of view that considering a similar nature or characteristics depending on the properties of the view that publicity, overlooking castle, the castle was divided into three types of places. Third, the views point for the public good are three items, vista point at which the gender perspective has six items that gender point of view places is set to seven items, was set up to view the most appropriate place to point gender. These results provide a framework for analysis and future system reliability and landscape simulation evaluation study is expected to be used as reference material.

The morphology and whole genome sequence of Spodoptera exigua nucleopolyhedrovirus K1 (SeNPV-K1) isolated in Korea were analyzed for the use as an eco-friendly control source against S. exigua. The polyhedra of SeNPV-K1 was amorphous with a size of 0.6-1.8 ㎛, and there was no external difference with the previously reported SeNPV. As a result of analyzing the nucleotide sequence of the whole genome, it was composed of 135,756 bp, which is 145 bp more than that of the previously reported SeNPV. The G+CG+C content was 44% and there were 6 homologous repeated sequences, so there was no significant difference from the previous report. As a result of ORF analysis, SeNPV-K1 had 137, two fewer than those previously reported, and 4 ORFs present only in SeNPV-K1 were confirmed. These 4 ORFs are non-essential genes and were not considered to have a significant influence on the characteristics of the SeNPV. The genome vista analysis showed that the overall sequence similarity between SeNPV-K1 and the previously reported SeNPV was very high. The whole genome of SeNPV-K1 analyzed for the first time in Korea was found to be similar to the previously reported SeNPV, but it was confirmed that it was a novel resource in Korea with different isolate.

The morphology and whole genome sequence of Hyphantria cunea nucleopolyhedrovirus W1 (HycuNPV-W1) isolated in Korea were analyzed for the use as an eco-friendly control agent against H. cunea. The HycuNPV-W1 had irregular tetrahedral polyhedra with a size of 1.5-2.2 ㎛ which is similar to that of previously reported HycuNPV isolated in Korea. As a result of whole viral genome analysis, HycuNPV-W1 was composed of 131,353 bp, which is 1,606 bp shorter than that of the previously reported HycuNPV. The G+C content was 45% and six of the homologous repeated regions were found, so there was no significant difference from the previous report. As a result of ORF analysis, HycuNPV-W1 contains total of 145 ORFs which is three ORFs less than the previous report, while two ORFs were exclusively found in HycuNPV-W1. The functions of these ORFs remains unclear and are not considered to have a significant influence on the characteristics of the HycuNPV. The genome vista analysis showed that the overall sequence identity between HycuNPV-W1 and the previously reported HycuNPV was very high. The whole genome of HycuNPV-W1 analyzed was found to be similar to those of the previously reported HycuNPV, however, it is supposed to be a novel resource in Korea with different isolate.

The flight control law designed for prototype aircraft often leads to degraded stability and performance, although developed control law verify by non-real time simulation and pilot based evaluations. Therefore, the proper evaluation methods should be applied such that flight control law designed can be verified in real flight environment. The one proposed in this paper is IFS (In-Flight Simulator). Currently, this system has been implemented into the F-18 HARV (High Angle of Attack Research Vehicle), SU-27 and F-16 VISTA (Variable stability In flight Simulation Test Aircraft) programs. The IFS necessary switching control law such as fader logic and integrator stand-by mode to reduce abrupt transient and minimize the integrator effect for each flight control laws switching. This paper addresses the concept of switching mechanism with fader logic of "TFS (Transient Free Switch)" and stand-by mode of "feedback type" based on SSWM (Software Switching Mechanism). And the result of real-time pilot evaluation reveals that the aircraft is stable for inter-conversion of flight control laws and transient response is minimized.
