Existing Speech feature extracting method in speech Signal, there are incorrect recognition rates due to incorrect speech which is not clear threshold value. In this article, the modeling method for improving speech recognition performance that combines the feature extraction for speech and silence characteristics normalized to the non-speech. The proposed method is minimized the noise affect, and speech recognition model are convergence of speech signal feature extraction to each speech frame and the silence feature normalization. Also, this method create the original speech signal with energy spectrum similar to entropy, therefore speech noise effects are to receive less of the noise. the performance values are improved in signal to noise ration by the silence feature normalization. We fixed speech and non speech classification standard value in cepstrum For th Performance analysis of the method presented in this paper is showed by comparing the results with CHMM HMM, the recognition rate was improved 2.7%p in the speech dependent and advanced 0.7%p in the speech independent.

This article is a case study of the ground improvement project which was carried out for manmade landfill. The project area is located near to Kapchun, Teajon and composed of the municipal wastes dumped, demolished building debris, coal ash and industrial waste made between 1983 and 1989. The DDC(dynamic deep compaction) based on the results of the test compaction at two representative locations was carried out from March 16, 1992 to Oct. 25, 1992. Field measurements and laboratory tests were carried out for ground improvement assessment and quality control for the DDC(dynamic deep compaction) work. From the results of field measurements and laboratory tests, it was found that the DDC work was successful: waste landfill was compressed considerably (${\fallingdotseq}$ 15% of full depth); and the strength was increased satisfactorily (${\fallingdotseq}$ 100% of original penetration resistance), Also, it is expected that the results of this work could be a guide to the future DDC work with the similar ground conditions, i.e. man-made landfills.

Objectives: This study was performed to screen target-specific inhibitors of ${\beta}$-catenin/TCF signaling whose functional activation plays an important role in early events in carcinogenesis. Methods: To investigate the activation or suppression of ${\beta}$-catenin/TCF transcription, we established a transiently transfected cell line with a constitutively active ${\beta}$-catenin mutant gene whose product is not degraded. This cell line was also co-transfected with luciferase reporter gene constructs containing either an optimized (TOPflash) or mutant (FOPflash) TCF-binding element. We investigated cytotoxic effects using a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium salt (MTS) assay. To find effective inhibitors of ${\beta}$-catenin/TCF signaling from medicinal herbs, the crude extracts of 99 types of medicinal herbs were screened using a luciferase assay system in HEK-293 and SH-SY5y cells. Results: At a concentration of $50{\mu}g$/ml, extracts of Angelica koreanae radix, Cannabis sativa semen, Ephedrae intermedia Schrenk radix, and Vitis rotundifolia fruit showed the following inhibitory effects on ${\beta}$-catenin/TCF signaling: $40{\pm}5.6%$, $23{\pm}6.1%$, $8{\pm}5.1%$, and $22{\pm}9.8%$ in ${\beta}$-catenin-activated HEK-293 cells and $9{\pm}4.7%$, $39{\pm}8.1%$, $39{\pm}6.4%$, and $42{\pm}10.1%$ in ${\beta}$-catenin-activated SH-SY5y cells, respectively. Crude extracts of E. radix were isolated by silica gel column chromatography, and two non-polar fractions of these extracts showed inhibitory effects on ${\beta}$-catenin/TCF signaling. Conclusions: In this study, we established a transiently transfected cell line as a screening system and found that various medicinal herb extracts had inhibitory effects on ${\beta}$signaling.

The purpose of this article is to study on the public administration in the perspective of I Ching(周易) which is the original philosophy and science of East Asia. I Ching is divided into two different schools, namely, the school of Image- Number I(象數易) and the school of Right Theory I(義理易). The school of Image- Number I are five science and technology(名 卜 醫 相 山) and astronomy, and so forth. And the school of Right Theory I are a Confucanist, a Taoist, a Mukist and all other thoughts. The meaning of Eastern Public Administration in mordern society is newer and better advanced concept, theory, and thoughts than western science and technology.

Nobody doubts about the importance of both academic and practitioner journal. Recently, however, many researchers in IS field have presented their concerns on the identity of journal of Information Systems Review (ISR). More specifically, they have been worried and concerned with the trend of deviation from the journal's original objective, which is to be the valuable practitioner-oriented journal in the IS field. With the same view in our mind, we attempt to figure out how to fix this trend. This article first analyzes the characteristics of all papers published in the ISR. Based on the findings, we present the future direction of ISR and discuss the submission guidelines about the more appropriate paper for the ISR in terms of methodology, type, and structure of paper. In addition, we propose the new review process for the newly submitted paper to the ISR. We hope this paper triggers a vigorous argument among many IS researchers and practitioners to make ISR the most prestigious outlet in the IS field.

Databases publicly available for online searching permit both citation and subject searching, however, subject searching has dominated the online search environment. Despite the power of citation searching, it may be underutilized This study explored the relationship between the number of cited references used in a citation search and information retrieval effectiveness, a relatively unstudied phenomenon. Three articles in the library and information science literature were chosen to represent sample questions. Cited reference searches were conducted for each article and each of its references. All searches were conducted in Social Scisearch and Scisearch on DIALOG. Relevance judgments on the retrieved citations were obtained from the authors of the original articles. This research focused on analyzing, in terms of information retrieval effectiveness, the overlap among postings sets retrieved by various combinations of cited references. The findings from the three case studies clearly showed that the more cited references used for the citation search, the better the performance, in terms of retrieving more relevant documents, up to a point of diminishing retums. In addition, generally the overall level of overlap among relevant documents sets was found to be low. Therefore, if only some of the cited references among many candidates are used for a citation search, a significant proportion of relevant documents may be missed. The analysis of the characteristics of cited references provided the ways to predict which cited refereces would be useful to improve information retrieval. The findings of this comprehensive exploratory study are of interest for both theoretical and practical reasons. They contribute to the development of a theoretical model for the effective use of the citation search. This model might also be implemented in operational online systems. In addition, the findings potentially will help online searchers improve their search strategies using the citation search so that they can better achieve their information retrieval goals: the retrieval of items relevant to a given question and the suppression of nonrelevant items.

This study aimed to review case reports of Korean medical treatments for sudden sensory neural hearing loss published in Korea from 1980 to 2016. We searched sudden sensory neural hearing loss through 6 major Korean web article search engines and search period was January 1980 to September 2016. Two researchers included studies on sudden hearing loss, clinical studies on korean medical treatments, and excluded in vivo studies, in vitro studies, non-original studies, published abstracts only, and studies not published in Korean or English. 19 articles were included in this study from 63 articles. Only one case report used Korean medical treatment alone. The most tools for treatment were acupunture, herbal medicine, pharmacopunture, moxibustion, cupping treatment and laser therapy. Most acupoints used in the treatment is SI19(聽宮). When patients got treated sooner, recovery rate was better. There was no direct relationship between recovery rate and degree of hearing loss. This study suggests that more research about sudden sensory neural hearing loss is needed in the future.

This study aims to make a contribution to the promotion of trade and economic development of South Korea, and, at the same time, call attention to the increasing trend of investment agreements concluded within Free Trade Agreements (FTA) by examining theoretically FTAs and dispute resolution and investigating systematically the conclusion procedure of agreements, and the system, institutions, and jurisdiction of dispute resolution, and presenting these findings to the government and investors involved. The most problematic aspect in the legal process of arbitration involving disputes over investment is that of arguments concerning the right of jurisdiction. When a dispute arises, even though an investor files for arbitration at an ICSID institution, the parties become involved in another energy-consuming argument even before proceeding to the hearing and decision of the original plan in cases in which the respondent of the dispute files an objection to the decision rights of the arbitral tribunal. As the main basis for this type of plea, the point of non-existence of jurisdiction is first raised where the applicable dispute does not fall under the range of investments defined in individual investment contracts or investment agreements such as a Bilateral Investment Treaty (BIT). To avoid an open-ended definition of investment for the range of investments, articles concerning investments in the FTA and NAFTA between Canada and the USA adopt the limited closed-list method. Article 96 of the FTA between Japan and Mexico applied the same abovementioned method of limited form of definition regarding range of investments and concluded BITs between member countries of APEC applied a similar method as well. Instead of employing the previously used inclusive definition, the BITs concluded between countries of Latin America and the USA are equipped with limited characteristics of an investment. Furthermore, to correspond with this necessary condition the three following requirements are needed : 1) fixed investment funding; 2) expected profits resulting from such investments; 3) and the existence of fixed risk bearing.

The use of program formats has slowly but surely developed into an important component of the television industry. This article examines the surprising gap between the constantly growing, multi-billion-dollar trade of program formats and their unclear and contradictory legal treatment. From both the social and commercial standpoints, television formats are valuable creations. Understanding the two products, the paper and program stages, of a television format and their respective markets, is fundamental to discussions of its legal protection. Interestingly, under current law, the less-developed stages of the process (program ideas and paper formats) are awarded more protection than the aired program format, which accumulates higher levels of investment, creativity, and expression. Internal industry mechanisms, such as vertical integration, damage to reputation, and industry institutions, exist in both markets and are still able to control and influence members' behavior to some extent. However, while the influence of internal industry mechanisms is still strong in the paper format market, in the program format market, which continues to grow, such mechanisms have weakened, amplifying the importance of a clear legal system. The absence of protection will certainly not completely eliminate the production of new program formats. However, these factors do not add up to a case against protection. The changes in the program format market in the last two decades support the theory that the overall effect of providing legal protection for TV formats would promote beneficial competition and encourage more original creations. The underlying question for television formats should not be whether to protect but rather how.
