We have already developed EMI reducing techniques using lossless compression by vertically differential EMI suppression method (VDE[1]). It applies lossless modulo reduction and data bit mapping optimization for low voltage differential signaling (LVDS) transmission lines, that reduces the probability of transient bit and EMI by 12 dB [6][7]. We also improved and optimized the VDE for low power LCD interface. With this modified VDE algorithm[8], the developed FPGA was measured the reduction of the power consumption of LCD circuit by more than 15 % compared to the conventional methods in the case of 14-in LCD with SXGA resolution. The VDE algorithm is based on the total image systematic approach. In the VDE method, the present image signals are subtracted for the 1H delayed image signals and transferred to a column driver through a PCB. As the vertical correlations for image signals are very high, we expected that most of the vertically subtracted image signals remain 0 level and transient cycles become very long. As a result, the power consumption and EMI are extremely reduced for the transferred image signals on a PCB. In this paper, we discussed our proposed method by emphasizing the fact that systematic approach are important based on not only display point of view but also total system point of view.

To find the candidate genes concerned with ovulation rate of sheep, Differential Display Reverse Transcription Polymerase Chain Reaction was employed to find the differently expressed cDNA controlling ovulation in the Small Tail Han sheep of polyembryony and in Tan sheep of single birth. Twenty-four primer pairs of three anchored primers and eight arbitrary primers were assembled to amplify the specialized bands from these sheep. Positive cross tests were applied to optimize the ascertainable PCR conditions in which different special bands can be identified by silver strain in one PCR tube. After eliminating the false positive PCR products by Northern hybridization, 24 differential display bands were acquired from the ovary in the Small Tail Han sheep. These EST bands were sequenced and 18 different ESTs were found in which five ESTs had several copies and 13 ESTs had only one copy. Comparing these ESTs with homologous sequences by BLAST in the GenBank, there were six ESTs with known open reading frame (ORF) and function, three ESTs with known ORF and no function, and 9 ESTs without homologous sequence. These ESTs partly represent several genes such as NOS2, tensin, TCRA, CDKN1A, ESR1 and ACTB which express especially in Small Tail Han sheep.

Differential Display PCR technique (DD-PCR) was used for the analysis of altered gene expression in hemocytes of Vibrio harveyi-infected Penaeus monodon. Forty-four combinations of arbitrary and oligo(dT) primers were used to screen for differentially expressed genes. A total of 79 differentially expressed bands could be identified from 33 primer combinations. These included 48 bands (61%) whose expression level increased and 31 bands (39%) decreased after V. harveyi challenge. Subsequently, forty-eight differential display fragments were successfully reamplified and cloned. A total of 267 clones were randomly selected and sequenced. The sequence analysis showed that 85 (31%) out of 267 clones were matched with sequences in the GenBank database which represented 24 different genes with known functions. Among the known genes, glucose transporter 1, interferon-related developmental regulator 1, lysozyme, profilin, SERPINB3, were selected for further confirmation of their differentially expression patterns by real-time PCR. The results showed increasing in expression level of the selected genes in shrimp hemocytes after microbial challenge suggesting the involvement of such genes in bacterial response in shrimp. The anti-lipopolysaccharide factor type 3 (ALFPm3) gene, previously reported in P. monodon (Supungul et al., 2002) was found among the up-regulated genes but diversity due to amino acid changes was observed. Increase in ALFPm3 transcripts upon V. harveyi injection is in accordance with that found in the previous study.

본 논문에서는 CM-MVL(Current Mode Multi-Valued Logic)을 이용한 Host와 LCD Controller 간에 인터페이스 회로를 제안한다. 제안한 회로는 기존의 LVDS(Low Voltage Differential Signaling)과 TMDS(Transition Minimized Differential Signaling)와 같은 전류 특성을 가지며, 3비트 동시 전송이 가능하여 동일한 전송 속도 하에서 보다 많은 데이터를 전송할 수 있다. 그리고 전류에 의한 데이터 전송을 통하여 노이즈에 강한 특성을 나타낸다. 제안한 회로는 HSPICE 시뮬레이션을 통해서 회로의 동작을 확인하였다.

We carried out the human visual evaluation on PDPs and LCDs to clarify the viewer preference and the related physical and physiological factors. In the subjective evaluation, the impression test using the semantic differential method was carried out. In the objective evaluation, the eye motion tracking system was used. Our study showed that considering the real usage, the optimum display for viewers was that which showed more soft and smooth image without blurring.

An advanced backplane circuit technology for AMOLED using amorphous silicon TFTs with commercial level reliability, uniformity and lifetime was recently integrated into a prototype device. Differential aging of T98>100 hrs at 200 cd/m2 brightness and >10,000hrs lifetime is demonstrated. A 2.2" QVGA ($240{\times}320$) prototype has been developed and shown having the above-mentioned high performance.

A new liquid crystal display (LCD) Data identified Time Extension (DiTEX) driving scheme with a high charged voltage is proposed. The different charged voltage owing to the differential charging time and various initial pixel-potential can be eliminated or diminished under this method. It is compatible with a 2-row inversion and can be realized into the commercial dual-sided gate circuits.

Differential display-PCR 방법을 이용하여, hCG 처리에 의한 참돔, Pagrus major의 난성숙 능력의 획득 경과시간에 따라 새롭게 발현하는 cDNA를 해석하였다. Differential display-PCR과 5'RACE 방법을 이용하여, 2,662 염기와 434개의 아미노산을 코드하고 있는 cDNA의 전염기배열을 결정하였다. DNA의 데 이터베이스인 GenBank 및 EMBL을 이용하여 상동성을 검색한 결과, 본 cDNA와 높은 상동성을 나타낸 유전자는 검색되지 않았다. 따라서 본 cDNA는 참돔의 난성숙 능력 유도와 함께 그 발현량이 증가하는 난성숙 관련 유전자로 판단되었다. 또한 본 cDNA에서는 protein kinase C 인산화 및 casein kinaseII 인산화 consensus 배열의 존재가 확인되었다. 본 연구에서 cloning된 난성숙 관련 유전자는 난여포에 hCG 처리 9～24시간 후에 그 발현량이 증가하였으며, GH-II (300 ng/ml)로 배양한 난여포에서 특이적으로 증가하였다. 또한 in vivo 실험에서 난성숙 관련 유전자는 난성숙 능력 획득 이전의 난소에서는 거의 발현하지 않았으나, 난성숙 능력을 획득한 난소에서 강하게 발현된 점으로 보아, hCG에 의한 난성숙 능력 유도에 성숙기간 중 새롭게 합성되는 난성숙 관련 유전자가 관여할 가능성이 높다.
