Screen filter of PDP TV plays an important role in satisfying the EMI/EMC specifications. Two types of filters, the mesh type and the sputter type, are used in PDP TVs, and this paper presents measurement results of the shielding effectiveness (SE) in the frequency range from 50MHz to 1GHz. Two methods were used for the measurement, one using network analyzer (NA) in an open area test site(OATS), and the other using the screen room. The overall conclusion is that the shielding effectiveness of the screen filter is related to the surface resistance of the screen filter. The mesh type screen filters are superior to the sputter types in the shielding effectiveness, which is varying with the frequency.

The purpose of this study is to assess for scattering object for the missile ejection round due to analysis of the human body effectiveness safely. To achieve this goal the measurement method of scattering objects by comparative 2 measurement methods studied, the risk of scattering of the object is evaluated. Result of this study, applied in Europe and Japan, based on the safety criteria for the human body effectiveness when missile ejection round. data showed is not effectiveness to the operator's body safely. Data showed that satisfies the safety criteria for missile ejection round in Europe and Japan through the similarity for the case studies. In case of these safety criteria does not exist regulation in South Korea, this study will be referred as guidelines are considered.

The purpose of this study is to develop a systematic framework that can scientifically and quantitatively evaluate the effectiveness of an LVC training system. The proposed framework is based on QFD(Quality Function Development) methodology. The process of developing the framework begins with identifying various needs of stakeholders related to the introduction of the LVC training system. Then the effectiveness areas and factors are derived based on the needs. The measured effectiveness for each factors on alternatives by L, V, C systems are finally synthesized into the one overall effectiveness of each training system for relative comparison among them. In addition, we developed an Excel$^{TM}$-based tool based on the proposed framework methodology to provide an ease-of-use environment for rapid evaluation on the effectiveness of each training system with the given stakeholder need importance combinations, training scenarios and assets. The suggested framework and the measurement tool are expected to be useful for efficient knowledge-based decision making on an acquisition of the LVC training system.

KJCCS(Korean Joint Command & Control System) is a system that integrate each military tactics C4ISR into JCS(Joint Chiefs of Staff) level. It is established in major CP(Commanding Post) and provides all battlefield situation in real time by sharing that between connection troops. The objective of this study is to suggest a way for the measurement of force improvement effectiveness of KJCCS. C2 model is applied to measure force improvement effectiveness of KJCCS. This study will be also present a requirement logic for C4ISR system acquisition later.

본 연구는 불질의 기반의 OPAC에서 정렬과 적합성 순위화알고리즘의 효과를 분석하고, 순위화의 성능을 평가하는 척도를 연구하였다. 연구결과 출판년도순 정렬이 저자명순, 서명순, 출판사순 정렬보다 우수하였으나 유의한 차이는 아니었다. 용어빈도수에 기반을 퍼지나 DNF 모델보다는 위치정보에 기반을 둔 알고리즘의 순위화 성능이 더 우수하였다. 6개의 순위화 성능평가척도간에 차이는 없었으며, 순위화시스템에서 정확률 P보다 분별력이 높은 단순 척도의 유용성이 확인되었다.

본 연구는 IR시스템 평가에 가장 많이 사용되는 R과 P가 순위화된 검색결과를 제공하는 시스템의 효과를 측정하는데 적절한가를 논의하고, R과 P 대신 순위화된 검색결과를 평가하는데 사용되고 있는 평가척도들을 고찰하고, 새로운 평가척도를 제안하였다. 또한 이들 평가척도가 어떤 환경에서 타당한지를 이론적으로 규명하고 사례를 들어 검증하였다. 11-포인트 평균정확률(평균)이 11-포인트 평균정확률(최고)보다 판별력이 있는 것으로 나타났고, 보다 간편한 여러 측정척도가 11-포인트 평균정확률을 대신할 수 있을 정도로 충분히 유사도가 높은 것으로 검증되었다.

This study was undertaken to measure the diffusibility and antimicrobial effectiveness of the medication used in clinical practice. To study the diffusibility of the root canal medicament, loss of formocresol and camphorated phenol from a cotton pellet after insertion into the pulp chamber of 260 molars prepared as routine endodontic treatment was measured. Measurement was done for the one time insertions and for the reinsertions using ultraviolet spectrophotometer. Antibacterial effectiveness against three microoganisms, Staphylococcus aureus, Staphylococcus epidermidis and a-hemolytic streptococcus, on the blood agar plate was observed by measurement of the inhibition zone with. various amount of medicaments. The following results were observed. 1. Nearly all of the medication were lost in the first day after insertion and the residual amount of camphorated phenol was greater than that of formocresol. 2. Residual amounts of medication in the reinsertion group were greater than that of the one time insertion group. 3. Within the pulp chamber diffusibility of formocresol was greater than that of camphorated phenol. 4. The amount of formocresol diffusing out from the tooth was greater than that of camphorated phenol. 5. Antibacterial effectiveness was observed from the residual amount of formocresol in the reinsertion group and in other groups no antibacterial effectiveness was observed.

This research describes the comparison broker's role and its effectiveness measurement using a developed logical framework of comparison shopping service. And verifies that seller-led comparison challenge method provide comparison information of products to buyers more efficiently. In electronic commerce, buyer's satisfaction of purchase (S) can be defined as an interactive function between seller's competitiveness vector (P) of products that supplied to the market, and buyer's informed level vector (B) of products that is known from a lot of sources. Then the buyer's informed level can be changed through the information analysis among products by transformation process using comparison matrix (C). So the role of comparison shopping is to construct a comparison matrix and to serve it to the buyers, and to change the buyer's informed level. The changed informed level influences a buyer's satisfaction, that improved satisfaction of purchase is defined as the effectiveness of comparison shopping. As a perfect provision and usage of comparison matrix is impossible cause of cognitive limit, the most efficient method for improving the comparison effectiveness is the comparison challenge that detects the comparison elements of the largest buyer's information efficiency, and then to be compared between elementary products selectively. This research verifies the substantial superiority of comparison challenge through television market data experiments.

본 연구의 목적은 TV홈쇼핑 광고를 시청하는 동안 일어나는 심리적 반응을 언어적 형태로 수집하고, 수집된 언어자료를 분석하여 광고효과의 측정 가능성을 탐색하는 것이다. 이를 위해 주부와 여자 대학생 40명을 대상으로 긍정평가 광고와 부정평가 광고를 시청하는 동안 나타난 심리적 반응을 사고발성법을 이용하여 언어자료의 형태로 수집하고, 자기보고식 측정으로 광고효과변인들과 광고반응 변인들을 측정하였다. 수집된 언어자료를 KLIWC를 이용하여 분석하여 긍부정평가 광고 간의 차이와 자기보고식 변인들 간의 상관을 살펴보았다. 검증결과, 긍정평가 광고와 부정평가 광고 간에 심리사회학적 변인뿐만 아니라 언어학적 변인에서도 차이가 나타났다. 또한 KLIWC의 다양한 변인들과 광고효과 변인들(구매자극도, 광고태도, 제품태도, 구매의도) 그리고 광고반응 변인들 간에 상관이 나타났다. 이러한 결과는 사고발성법과 KLIWC의 언어분석을 이용하여 TV홈쇼핑 광고 효과를 측정할 수 있는 가능성과 심리적 반응 프로파일을 구성할 수 있는 가능성을 시사하여 준다.
