I-V characteristics of LIGBT is studied by SPICE simulation which includes device parameters and process parameters. Analysis and modeling of ON-resistance are discussed in this paper. Compare with experimental values, SPICE simulation and modeling results show that our simulation is valid for LIGBT.

한자 아닌 것으로 한자를 대용하고 개별화할 필요가 있을 때 한자의 새김과 소릿값의 짝은 대단히 편리하다. "내 이름은 빛 광 ㅅ 자, 아침 조 ㅅ 자요"처럼 우리는 일상 담화나 전화 등에서 예사로 이런 새김만을 이용하는 한자 생활을 해 왔다. 한말에만 있는 새김의 이러한 쓰임새는 적극적으로 확대할 만 한 것이다. 한자의 새김 -소릿값의 짝은 (1) 일상적인 담화에서 한자를 완전히 대신하는 것과 마찬가지로 글을 쓸 때에도 한자를 대신할 수 있고, (2) 한자의 전산 입력을 아주 쉽게 하며, (3) 학술적으로는 더욱 긴요하다. 학술용으로 필요한 한자는 적어도 1 만에서 5 만을 넘는데, 이들이 다 전산화한다는 것은 조만간 도저히 기대할 수 없다. 그렇기 때문에 우리는 당장 긴급한 대로 학술용의 한자를 전면적으로 대용할 수 있는 수단으로 새김 -소릿값을 생각하기에 이른 것이다. 그러므로 이제 국학과 전산학 분야의 협력을 통해 한자마다 고유한 새김과 소릿값의 짝을 다듬어 표준화하는 일이 필요하게 되었다.

Parameters of soluble solids, amino acids, catechins, and color difference of 24 green tea samples from China and Korea were determined. The levels of soluble solids, amino acids, total catechins, and infusion lightness in tea samples from Korea were higher than those from China. Concentrations of epigallocatechin galate and epigallocatechin in teas from China were higher than tea samples from Korea. Geographical origin of teas from the 2 countries was discriminated using parameters of infusion lightness, gallocatechin, and total catechins and applying principal component analysis.

In this paper, we discuss the problem of continuous k.nearest neighbors (CKNN) monitoring over distributed streams wavelet synopses, which also considered sliding window structure under stream based kNN query. We developed traditional skylines techniques and propose a new method which called DR.skylines to process CKNN queries as a bandwidth.efficient approach. It tries to process CKNN queries on synopses for optimized sliding window time and space computation.

The purpose of this study is to examine the structural relationship among factors affecting learning engagement, satisfaction, continuance intention in China-MOOC. For this study, data were collected from 334 students who were taking MOOC classes. and structural equation model ling analyses were employed to examine the causal relationships among variables. From the results of this study, First, self-regulated learning and interaction significantly affected learning engagement. Second, interaction had direct effects on satisfaction. Third, satisfaction significantly affect continuance intention. Furthermore, satisfaction mediated relationships between interaction and continuance intention. These results imply that self-regulated learning, interaction, learning engagement should be considered for designing and implementing China-MOOC learning. Further implication are discussed in the study.

To establish a method to evaluate the quality of the printed microarray and DNA fragments' immobilization. The target gene fragments that were made with the restriction display PCR (RD-PCR) technique were printed on a superamine modified glass slide, then immobilized with UV cross-linking and heat. This chip was hybridized with universal primers that were labeled with cy3-dUTP, as well as cDNA that was labeled with cy3-dCTP, as the conventional protocol. Most of the target gene fragments on the chip showed positive signals, but the negative control showed no signal, and vice versa. We established a method that enables an effective evaluation of the quality of the microarrays.

Taiwanese abounds with verbal complexes. Among them, phasal complexes, resultative complexes, and directional complexes are alike in that their second component denotes some sort of result. Moreover, they behave similarly in that they can occur in V-ho-Y, V-e/be-Y, and V-bo-V forms. Despite the similarities, they still differ from one another in several aspects, such as whether objects are allowed inside or after the verbal complex, whether infixing changes their basic meaning, etc. This paper examines their individual properties carefully and proposes that these three types of complexes are all different from one another in their formation and thus the difference in their syntactic behavior. Directional complexes are syntactic phrases, resultative complexes are compounds derived in syntax, and while some phasal complexes are also syntactically derived compounds, others are compounds formed in the lexicon. This paper aims to argue that words (or compounds in this case) can be formed in syntax as well as in the lexicon.

Ground vibration at Gil-dong in Seoul induced by the 5th ling of Seoul Subway is predicted using various prediction methods and compared with measured vibration. Also, several issues on the improvement of prediction methods are discussed. Furthermore, as an alternative vibration source, measured vibration acceleration level(VAL) on the tunnel wall of the Bundang line of Seoul Subway is applied to the prediction of the VAL at the location mentioned previously. Then requirements accompanied to the suggestion of the new vibration source appropriate to the condition of Seoul Subway.

The purpose of this paper is to clarify analytically the relation between the characteristics and the pricing of the products of individual manufacturers, so we can offer beneficial information for designing and developing products. Light trucks of 1 ton to 4 ton have been taken up as examples. We carried out analyses based on the information on the evaluations of the functional characteristics by surveying the specifications obtained from light truck catalogues.

Seeds of Paulownia coreana were collected, extracted with acetone-$H_2O$ (7 : 3, v/v), concentrated under reduced pressure and successively fractionated with n-hexane, methylene chloride, ethyl acetate and water on a separatory funnel. The $H_2O$ soluble fraction was chromatographed on a Sephadex LH-20 column using aqueous methanol and ethanol-hexane as washing solvents. Two isomeric phenylethanoid glycosides, verbascoside (1) and isoverbascoside (2), and one epimeric phenylethanoid glycoside, campneoside II (3), were isolated and their structures were elucidated on the basis of chemical and spectroscopical data.
