창의성 및 정보과학적 특성을 기반으로 한 정보영재 판별도구 개발연구
신승용,신수범,배영권,이태욱 한국컴퓨터교육학회 2004 컴퓨터교육학회 논문지 Vol.7 No.4
오늘날 정보화가 빠르게 진행되면서 정보과학의 중요성이 수학, 과학의 중요성 못지않게 대두되고 있기 때문에 이 분야의 영재 역시 조기에 판별하여 교육시켜야 한다는 필요성이 강조되고 있다. 하지만 이에 대한 연구는 초보적인 단계에 머물고 있다. 이에, 본 연구에서는 영재의 판별에 대한 이론적 고찰을 통해서 영재의 특성, 정의 및 판별방법과 도구의 제작과정을 살펴보고 영재의 올바른 판별과정을 조사, 분석하였다. 또한 이를 바탕으로 정보과학의 기반이 되는 이산수학의 특성을 규정하여 이를 바탕으로 정보영재의 특성 및 정의를 내렸으며 이를 근거로 정보영재를 판별할 수 있는 도구를 제작하였다. 판별도구를 이용하여 적용한 결과 판별도구는 신뢰성이 있는 것으로 분석되었으며 향후 정보영재의 의미 있는 판별도구로 활용될 수 있을 수 것이다. Since the science of information is appearing no less important than mathematics and natural science as our society is rapidly becoming information-oriented, the necessity to distinguish prodigies of this field and to educate them as early as possible is also being emphasized. Unfortunately, however, the pertinent study is still in its beginning stage. In this study, I have reviewed the character, definition and method to distinguish prodigies and the procedure of developing a test, as well as researching and analyzing the proper process of distinguishing prodigies, through theoretical contemplation on the method of distinguishing the gifted children. Also, I have characterized and defined the information prodigies after clarifying the character of 'Discrete Mathematics' which becomes the basis of the science of information, paving the way to make a test method that can distinguish those information prodigies. As a result of our applying the system by using the distinction test, it turned out that the distinction test was pretty reliable. Accordingly, it can be utilized as a significant distinction test for information prodigies in the forthcoming future.

In this paper, an improved source routing protocol is designed for mobile ad hoc network with unidirectional link. In the Mobile ad hoc network, nodes communicates with each other by usingmulti-hop method without any base station. In order for a source mobile node to send its data to a destination node through other intermediate nodes, mobile ad hoc routing protocol is required. DSR and AODV are the representative routing protocols for Mobile ad hoc network. However, unfortunately, current DSR and AODV routing protocol versions support mobile ad hoc network only with bidirectional links. We proposed and simulated a source routing protocol supporting mobile ad hoc network with unidirectional links which was based on DSR and AODV routing protocol. The result of simulation show average route setting time of 0.004~0.007 second and average date receiving rate of 97~97%.

The purpose of this study is to investigate between financial support and actual results of sporting game of the Amateur Athletic Association in C-province and the general cities, others provinces. The settled accounts of budget on the C-province Amateur Athletic Association grew to the increased rate of nominal budget than settled accounts of budget inthe previous year, but decreased the settled accounts of real budget think over the rate of raise in prices than the increased of nominal budget. The more the settled accounts of budget on the Amateur Athletics Association-grew, the better the marks obtained of sporting events in a nation athletic meet becamed. Namely, there is a slight growing tendency to bring about good results that the settled accounts of the Amateur Athletic Association budget all of cities, others provinces increased, but didn't absolute.

This paper presents a clock regenerator using two 2<SUP>nd</SUP> order Σ-Δ (sigma-delta) modulators for wide range of dividing ratio as defined in HDMI standard. The proposed circuit adopts a fractional-N frequency synthesis architecture for PLL-based clock regeneration. By converting the integer and decimal part of the N and CTS values in HDMI format and processing separately at two different Σ-Δ modulators, the proposed circuit covers a very wide range of the dividing ratio as HDMI standard. The circuit is fabricated using 0.18 ㎛ CMOS and shows 13 ㎽ power consumption with an on-chip loop filter implementation.
