최근의 폭발적인 인터넷 사용의 증가와 또 그것과 유사한 품질의 서비스를 이동중에도 제공 받고자 하는 사용자의 요구와 음성통화 시장의 포화에 따라 무선 데이터 시장을 새로운 돌파구로 보는 제조업체 및 서비스 제공자의 노력으로 IMT-2000 서비스가 이미 진행되고 있다. 비록 2세대 디지털 셀룰러에서 IMT-2000으로의 진화가 현재 지지부진 하지만, 2010년경의 데이터 사용량 예측을 참고로 할 때 새로운 시스템의 출현이 필연적이다. 본 논문에서는 최근까지 논의된 4세대 이동통신에 대한 시스템 및 서비스의 비전을 제시하고자 한다. IMT-2000에서 화상전화를 목표로 하였다면, 4세대에서는 Telepresence의 완벽한 구현과 유비쿼터스 시대로의 첫걸음으로서 다양한 네트워크와 컨버전스를 강조한다. 본 논문에서 이 두 가지 특징을 중심으로 4세대의 비전을 기술하고자 한다.

TFT-LCD 모니터 및 TV의 핵심부품인 TFT/Color Filter를 제조하는 공장라인에서 제품의 품질에 중요한 역할을 하는 것은 유리기판에 TFT와 Color Filter을 형성시키는 노광공정(Exposure)이다. 이러한 TFT/Color Filter를 생산하는 공정내에서 노광기는 핵심기술이므로 진동에 대하여 엄격하게 관리되어지고 있다. 그리고, TV 및 TFT-LCD 모니터의 크기가 큰 것을 사용자의 요구로 TFT/Color Filter 생산 공장은 세대가 거듭될수록 사용되어지는 유리기판의 크기도 따라서 커지고 있다. 이러한 유리기판의 크기 증가는 공정라인에서 진동에 더욱더 취약해지는 결과를 초래하므로 보다 엄격하게 진동관리가 필요하게 된다. 이에, 본 논문에서는 기존 세대인 1～5세대 TFT-LCD 공장 현장에서 노광기의 진동실태를 수집하여 파악하고 Maker에서 제시하는 자료와 비교/평가하고, 문제점을 확인한다. 이를 기초로 수정/보완되어야 할 사항을 검토하며, 차세대인 6∼7세대 노광기에 대한 진동저감 대책을 위한 시스템을 설계하는 절차서에 대한 예를 들었으며, 최적의 진동저감 대책에 대한 설계안의 방향을 제시하였다.

차세대 ULSI 소자의 다층금속배선을 위한 저유전 물질중에서, 기존의 절연막인 TEOS-$SiO_2$ 증착 장비 및 공정을 최대한 이용할 수 있으며, 물성 또한 TEOS oxide와 유사하다는 점에서 적용 시점을 앞당길 수 있는 SiOF 박막과 SiOC 박막의 특성에 대해 고찰해 보았다. 1세대 저유전 물질이라 할 수 있는 SiOF는 후속공정에도 안정적인 상태의 박막을 얻기 위해서는 3.0이하의 유전상수를 얻는 것이 불가능한 반면, SiOC는 3.0 이하의 유전상수를 가지는 안정적인 박막을 얻을 수 있다. SiOC 물질은 저밀도의 단일물질로서, 물질 내부에 후속공정에 영향을 미칠만한 기공을 포함하지 않기 때문에 후속 CMP 공정에 적합하였으며, $450^{\circ}C$이하의 열 공정에서도 응력변화 및 박막성분 탈착이 거의 일어나지 않는 점 또한 SiOC 박막의 우수한 후속공정 적합성을 보여주는 결과였다. 이러한 결과를 종합하여 볼 때, 현재 사용되고 있는 1세대 저유전 물질인 SiOF 박막을 대체할 차세대 저유전 물질로 SiOC 물질이 유망하며, 이는 3.0 이하의 유전상수를 요구하는 Gb DRAM 소자나 보다 빠른 동작속도가 생명인 논리회로(logic circuit) 소자에 적용될 경우 큰 소자특성 개선이 기대된다.

Since the IMF crisis, the competition among banks in Korea has fiercely intensified. To survive in the severe competition, several leading banks including Industrial Bank of Korea (IBK) have recently developed their own proprietary systems called 'the Next-Generation Systems(NGS).' This case study was to answer several important issues as follows; 1); the reason why a bank make huge investment in the IT infrastructure; 2) the development methodology of the NGS; 3) the new architecture of the NGS; 4) the governance structure of the NGS investment; and 5) the effects of the NGS on the development of new products. To achieve such goals, a systematic tandem interview method and many archival reports from IBK were utilized. The conclusions are summarized as follows: First, the NGS has contributed to the integration and simplification of business processes. Second, new products as demanded in the market can be developed much faster through the NGS. Third, the change management of IT infrastructure is critically important. Fourth, the systems architecture can be different according to the IT governance. Fifth, the alignment of the NGS and business processes is most important to obtain the organizational goals.

In this farer, An ADSRC(Advanced Dedicated Short Range Communication) packet communication system developed by ETRI is introduced. The ADSRC system has been developed to provide high-speed, short-range wireless racket communication in roadside environment for mobile office services. The requirements of the ADSRC system for mobile office services and the system design specification to meet them with regard to mobile of nce environment are discussed. The ADSRC packet communication systems consist of the MAC(Medium Access Control) Processor block the OFDM() modem block and the RF block. The MAC processor block handles medium access control. The OFDM modem transmits data packets at up to 24Mbps adaptively and recovers the data from RF block. The ADSRC packet communication system architecture is described.

Degree of heterosis and gene distributions of several agronomic characters of rice were studied with F$_1$ and F$_2$ generations of 9-parent partial diallel cross in 1983-1984. Degree of heterosis was greater in F$_1$ hybrids than F$_2$ hybrids for culm length, panicle length and number of panicle and the heterobeltiosis could be observed in culm length and number of panicle from several crosses. Incomplete dominance was exhibited by culm length, panicle length and number of panicle in F$_1$ and F$_2$ generations.

This study poses a question on whether the Jangmadang Generation, which has been the focus of the sociological interest, can form an actual generation by transcending the social classes, status of students, ethnicity, and gender, etc. Therefore, in this study, the author compared the consciousness of the Jangmadang Generation in terms of politics, education, society, compliance with law, and education with their preceding generations. The data used in this study were gathered from the North Korean defectors who defected within the past five years over the period from November to December 2016. A total of 200 questionnaires were used for data analysis, which was conducted using SPSS 20.0, in order to show differences between groups and perform frequency analysis. The analysis results showed that the consciousness of the Jangmadang Generation in politics, society, compliance, and education was lower, while the economic consciousness was significantly higher compared to earlier generations. As their objective generational status, the Jangmadang Generation had experienced the 'March of Ordeal' and 'Collapse of Public Education' while they were still teenagers. Such a difference in their generational status influenced the formation of different consciousness as a generation compared to the earlier generations. Compared to the earlier generations who received 'proper public education,' the Jangmadang Generation, who did not receive 'decent public education' shows a generally lower level of consciousness compared to the earlier generations. As such, the Jangmadang Generation has the potential to form a separate generation with a different generation consciousness from that of earlier generations.

The information represented by graphic is preferred more than by text to the game generation familiar to computer games in the cognitive style. The learning to solve the math problems represented by graphic is significantly effective to improve learner's problem-solving power in math education. In this paper, we proposed a method of graphic representation of mathematical sentences for effective learning of the game generation. The proposed method arranges the unit informations in the logical structure and represent the logical interrelation between the informations by symbols, line segments, or arrows using the graphic elements with good visibility for the game generation to recognize easily and to understand accurately the logical meaning. The proposed method is able to represent accurately the math sentences until the detail level that appears the tense and the voice of the sentences differently from the previous graphic representation method's ability. The proposed method could be used as learning tools and used widely to represent graphically mathematical informations for the instructional scaffolding of an educational game in oder that the game generation could learn effectively.

Torymus geranii was found to be a ectoparasitoid attacking the larvae of Dryocosmus kuriphilus. T. geranii has longevity of a $42.8{\pm}9.8$ days at $20^{\circ}C$ and $26.5{\pm}11.0$ day at $25^{\circ}C$ under conditions supplied with 100% honeydew. Oviposition numbers at 20 and $25^{\circ}C$ were $22.3{\pm}12.5$ and $42.2{\pm}18.4$, respectively. The eggs were oval in shape, measuring $0.56{\pm}0.33$ mm in length. The larvae, $2.94{\pm}0.18mm$ in length, was white and length of male and female pupae were $2.01{\pm}0.18mm$ and $2.73{\pm}0.09mm$, respectively. T. geranii had two generations with overwintering generation emerged on late May to early June at Chunchon, central part of Korea, however showed three generations with overwintering generation emerged on middle May to early June, the first one on late June to early July, and the second one on late July to earlyl August.

웨어러블 컴퓨터와 같은 차세대 PC의 진화 방향은 인간이 느끼는 색상, 빛의 밝기, 소리, 향기, 맛, 감촉 등의 오감 정보의 효과적인 융합과 재현 및 사용자 중심의 인간-기계 관계의 형성으로 정의 된다. 그러나, 기능의 다양함과는 별개로, 휴대의 편이를 위한 착용형태의 H/W 플랫폼 개발은 효율적인 5 감 정보의 융합 및 재현에 제약을 가하고 있는 실정이다. 본 논문에서는, 현재 정부에서 국가적인 차원으로 현재 연구 개발중인 차세대 PC 플랫폼 기반에서의 효율적인 5 감 정보의 융합 및 재현이 가능한 S/W 플랫폼을 구현하며, 보다 효율적인 융합 및 재현을 위한 새로운 제어 메시지 형태를 제안한다.
