국설계가 수행된 후 이를 바탕으로 product ordering 을 하기 위해 물자 설계가 수행된다. TDX-1 시스팀의 물자 설계를 위한 TDX-1 dimensioning system 에서 수행되는 내용은 H/W device traffic dimensioning, cable dimensioning, parts calculation, system price estimation, power consumption calculation, spare parts calculation, system optimization 으로서 이들에 대한 구체적인 수행 방법과 절차를 제시하였다. 효율적인 물자산출을 위해 전산 패키지인 "DIMEX"를 개발하였다. DIMEX의 source program 은 C-language로 되어 있으며 UNIX operating system에서 수행된다. DBMS는 troll을 사용하고 있다. Memory size는 troll을 제외하고 약 10,000 block 정도이다. 현재에도 DIMEX 에 대한 기능 보완 및 추가가 VAX750(System5)에서 계속 진행 중에 있다.

지난해 9월 16일 미국 특허 역사상 대혁명이라고 할 만한 특허법 개정이 이루어졌다. 개정된 미국 특허법이 특히 의미를 갖는 것은 한 미 FTA가 올해 3월 15일자로 발효되면서, 우리 기업의 미국 진출이 더욱 활발해지게 되고 특허 분쟁가능성도 높아졌기 때문이다. 미국 특허법의 주요 개정사항으로 가장 주목을 받고 있는 것은 "선발명주의" 포기와 "선출원주의" 도입이지만, 이 밖에도 발명자가 아닌 자의 특허출원 허용, 공지공용기술의 국제주의 채택, 최선 실시예 (best mode)의 기재의무 완화, 특허괴물(patent troll)로도 불리는 특허비실시기업(NPE)의 소송남발을 억제하기 위한 특허 소송 요건 강화 등 중요한 내용을 많이 담고 있으므로, 미국에 진출하였거나 진출을 예정하고 있는 기업들은 미국 특허법의 개정사항을 유의 갚게 살펴볼 필요가 있다.

This paper concerns a method for micro-wave imaging. The image reconstruction of a perfect conducting cylinder by phase and amplitude measurement using the X-Band multifrequency is presented troll the simulated data. The high degree of range resolution is achieved using large signal band-width and cross-range resolution is obtained by doppler processing. The comparison of image reconstruction between range doppler processing and circular convolution algorithm is also shown.

This paper deals with characteristics analysis of Doubly-Fed Induction Generator (DFIG) in the supersynchronous speed regions. by control of voltage fed to the rotor using for bidirection control. This rotor voltage is controlled by con troll of inverter switching frequency and fire angle. Characteristics of DFIG is analyzed by steady-state algebraic equations of the equivalent circuit using numerical analysis. And it is compared with results of experiment. Consequently, this paper presented to find the optimal magnitude of voltage fed to the rotor for maximum power and PF, using result of characteristics analysis.

Dissolved oxygen (DO) is an important factor in ecosystems. However, the analysis of DO is frequently rather complicated because of the nonlinear phenomenon of the river system. Therefore, a convenient model-free algorithm for DO variable is required. In this study, a data-driven algorithm for predicting DO was developed by combining XGBoost and an artificial neural network (ANN), called ANN-XGB. To train the model, two years of ecosystem data were collected in Anyang, Seoul using the Troll 9500 model. One advantage of the proposed algorithm is its ability to capture abrupt changes in climate-related features that arise from sudden events. Moreover, our algorithm can provide a feature importance analysis owing to the use of XGBoost. The results obtained using the ANN-XGB algorithm were compared with those obtained using the ANN algorithm in the Results Section. The predictions made by ANN-XGB were mostly in closer agreement with the measured DO values in the river than those made by the ANN.

This study had been conducted to determine morphological characteristics of soil in the major districts cultivating flue-cured tobacco plant. Also native soil productivities were measured by means of bioassay planting tobacco plant without fertilizer at 87 selected soils through field experiment. Morphological characteristics of troll affecting the dry weight of tobacco leaves cultivated in the field were investigated Among soil morphological characteristics, topograpy, slope, topsoil depth, soil depth, and soil texture had influenced with high significant on the dry weight of tobacco leaves. For prediction of dry weight (productivity) of tobacco leaves without fertilizer , multiple regression analysis were introduced using soul morphological characteristics. A combination of topography, slope, topsoil depth, and soil texture was very reliable for prediction of productivity. The regression equation was y = -16.88 -14, 34$X_1$ +20.43$X_2$ +50.21$X_3$ -7.54$X_4$ +13.45$X_5$ R = $0.670^{**}$ Where $X_1$ : Topography $X_2$ : Slope $X_3$ : Topsoil Depth $X_4$ : Soil Depth $X_5$ : Soil Texture

COVID-19 (Corona Virus Disease-2019) is an infectious respiratory disease caused by the most recently discovered coronavirus, SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona virus-2). This new viral disease was unknown before the outbreak began in Wuhan, China, in December 2019. As of November 16th 2020, it affects about 54.3 million populations, death troll increased to 1.32 million cases in worldwide. Whereas in India 8.85 cases are infected with COVID-19, of which 1, 30, 112 cases were died. Till now there has been no specific anti-virus drug or vaccines are available for the treatment of this disease, the supportive care and non-specific treatment to the symptoms of the patient are the only options in Biomedicine, the entire world turns its attention towards alternative medicine or Traditional medicine. Siddha medicine is one of the primordial systems of medicine practiced in the southern part of India, it dealt a lot about pandemic, and its management. This review provides an insight into Pandemic in Siddha system and its management in both ancient history and modern history, National and state level Government policies related to current pandemic, World Health Organization (WHO) guidelines on usage of unproven drug during infectious disease outbreak, Preparedness of Siddha system during a pandemic outbreak Challenges and Recommendations.
