Riding on the wave of the information technology revolution, a slow of internet venture businesses (IVB) came into being. Hence, one of the recent developments in Korean capital market has been the proliferation of IVB, which is in accordance with the worldwide trend of ‘new economy’. Although the fair valuation is crucial for the nourishment of IVB, it is difficult to apply traditional valuation methods to these firms without reservation. It is due to the facts that most venture firms have little records of performance, grow unprecedently fast, and have highly uncertain future. The main purpose of this study is to suggest performance evaluation system of IVB and to develop KPE (Key Performance Indicators). Our empirical study is based upon Kaplan & Norton’s Balance Scorecard (BSC) approach. Specifically, our research has been conducted by the following two subsequent procedures: Firstly, seven internet venture firms have been selected and their executives have been interviewed by FGI(Focus Group Interview) method. Based upon these results, performance indicators have been developed. Secondly, by using the above mentioned BSC items (i.e., financial perspective, customer perspective, internal perspective and innovation & learning perspective), questionnaires have been constructed and sent to IVB through e-mail as well as over the Fax. Among the collected 110 samples, reliable 106 samples have been used to build BSC model and to draw our conclusion. In the future study, it would be much better to consider the role of strategy in IVB and the causal relationship among Key Performance Indicators of BSC.

The purpose of this study were to analyse the consciousness of persons in charge of fashion industries and to provide some basis data for development of the fashion internship program which could reduce differentiation between fashion colleges and fashion companies. Fifty national fashion brands had been randomly selected and question researches had done from August twenty-seventh to October thirtieth by the visit, mail, fax and e-mail etc. Date analyses were conducted with SPSS program on the frequency, t-test and ANOVA. The results were as follows. The companies selected interns by documents and interview, however, in the future they will prefer to accept interns by appraising some task. They preferred to apprentice for two months with some simple job and tasks. The companies wanted some prerequisite study such as major curriculum, human nature education, computer education. And each division wanted different curriculum. They wanted to be joined with industrial disaster insurance for intern and to be given allowance and credit. They also preferred reputation ratio of industry : college as $70\%$ : $30\%$ for intern reputation. There were some vitalizing method of fashion internship such as discriminated fashion internship program, government support for industries, universities and students, organization opening to connect industry and . university, mentor-system and credit system introducing, curriculum reforming in the university.

It is a very important to manage inventory quickly and accurately in Refrigerated commercial warehouses in which a lot of logistics are often shipping and receiving. Because most of systems for managing refrigerated warehouses consist of COBOL, it will be raised maintenance costs. There is no service for consignees who are consumer of refrigerated warehouses and they use only a fax or a phone for orders. In this paper, we design a web mobile middleware platform supporting legacy systems and based on SaaS which supports a variety of value-added services which are fit consignees, solving problem of outdated legacy systems and no services for consignees.

G3 팩스가 G1 팩스나 G2 팩스와 구별되는 점은 문서 이미지를 스캔하여 얻은 아날로그 신호(전압)를 디지털 신호로 바꿔주는 A/D 변환과 여기서 얻어진 디지털 신호를 전송을 위해 다시 아날로그 신호(주파수, 위상 진폭)로 바꿔주는 모듈레이션 과정이 중간에 신호를 압축하여 표현하는 코딩 단계가 있다는 것이다. 따라서 G1 팩스나 G2 팩스에 비해 s훨씬 적은 신호를 가지고 문서 이미지를 표현할 수 있으며, 결과적으로 전송속도가 빨라지는 것이 된다. 표준 A4용지는 수평 방향으로 1728개의 픽셀, 수직방향으로 1145라인의 픽셀로 구성된다. 따라서 층 1,978,560($1728{\times}1145$) 비트의 데이터가 A4용지 한 장에 포함될 수 있는 것이다. 팩스가 이런한 표준 A4용지를 스캔하게될 경우 수캔되는 매 라인에는 1728개의 검은색(글자 및 그림) 및 흰색 (여백)픽 셀들이 존재한다. G3 팩스는 서로 다른 Run Length에 비교적 짧은 특정 코드를 미리 할당해 놓고 실제 픽셀들 대신 이러한 코드들을 모듈레이션해서 전송한다. 따라서 전송속도는 단축된다.

CCITT G.721, G.723 standard ADPCM algorithm is implemented by using TI's fixed point DSP start kit (DSK). ADPCM can be implemented on a various rates, such as 16K, 24K, 32K and 40K. The ADPCM is sample based compression technique and its complexity is not so high as the other speech compression techniques such as CELP, VSELP and GSM, etc. ADPCM is widely applicable to most of the low cost speech compression application and they are tapeless answering machine, simultaneous voice and fax modem, digital phone, etc. TMS320C50 DSP is a low cost fixed point DSP chip and C50 DSK system has an AIC (analog interface chip) which operates as a single chip A/D and D/A converter with 14 bit resolution, C50 DSP chip with on-chip memory of 10K and RS232C interface module. ADPCM C code is compiled by TI C50 C-compiler and implemented on the DSK on-chip memory. Speech signal input is converted into 14 bit linear PCM data and encoded into ADPCM data and the data is sent to PC through RS232C. The ADPCM data on PC is received by the DSK through RS232C and then decoded to generate the 14 bit linear PCM data and converted into the speech signal. The DSK system has audio in/out jack and we can input and out the speech signal.

현재 IT 인프라 기술이 상당한 발전을 이루고 있으며 고급 인프라를 활용한 IT 기술들이 나날이 발전하고 있다. 지금의 정보화 사회에 지대한 영향을 미치고 있는 인터넷을 포함한 수 많은 IT 정보기술들은 각 사회분야에 걸쳐 해당 분야의 정보의 질을 높이고 있다. CTI (Computer Telephony Integration) 기반 콜센터 시스템 또한 IT 인프라의 발전에 발 맞추어 효율적인 정보 제공을 위한 정보 기술이 상당히 많이 발전해왔다. 기존의 콜센터 시스템은 PSTN 망 기반의 전화 중심의 정보제공만 가능한 반면에, 현재 콜센터 시스템은 PSTN 기반이 아닌 IP 기반 인프라를 활용하여 IP 기반으로 제공할 수 있는 여러 기술을 접목시킨 하나의 통합 솔루션 시스템으로 발전하고 있다. 콜과 관련된 서비스만 제공하는 것이 아니라 Fax, E-mail, Instance Messaging 등 여러종류의 서비스를 제공하기 위해 시스템 구성이 변화하고 있는 추세이다. 하지만 현재 콜센터 시스템은 청각장애인을 위해 제공할 수 있는 서비스가 존재하지 않으며 이에 대한 연구 또한 미비한 상태이다. 이에 본 논문에서는 청각장애인을 위한 서비스 제공을 위해 스마트폰 인프라에서 서비스를 제공 받을 수 있는 CTI 시스템을 설계 하였다.

In this paper, we propose an effective method for the distinction between machine-printed and handwritten Korean address images. It is important to know whether an input image is handwritten or machine-printed, because methods for handwritten image are quite different from those of machine-printed image in such applications as address reading, form processing, FAX routing, and so on. Our method consists of three blocks: valid connected components grouping, feature extraction, and classification. Features related to width and position of groups of valid connected components are used for the classification based on a neural network. The experiment done with live Korean address images has demonstrated the superiority of the proposed method. The correct classification rate for 3,147 testing images was about 98.85%.
