An elevator maintenance company maintains many types of elevators from many manufactures. So, they want to use manufacture- or type-independent elevator remote monitoring system. To do this, data logger, that receives elevator operating state data from sensor module installed in elevator and transfers the data to database, is required. In this paper, we design and implement data logger of elevator remote monitoring system for providing elevator operation state information to elevator maintenance company. Data logger receives elevator operation state data from sensor module installed in elevator, decodes data, and converts to API data for transferring elevator operation state data to server. In this paper, we describe the implementation of data logger using python, and show that our implementation of data logger is successfully operating in a real elevator operating environment via log message displayed at screen.

인터넷 표준 문서인 XML(Extensible Markup Language)이 구조적인 내용만을 갖고 있기 때문에 문서를 보여주기 위한 표현 정보를 포함하는 스타일 시트(style sheets)가 필요하다. 이를 위해 W3C(World Wide Web Consortium)에서는 XML 문서의 구조적인 접근을 위한 XPath(XML Path Language)와 문서의 내용구조를 변환하기 위한 XSLT (Transformations), 그리고 포맷팅 정보를 위한 XSL-fo(XSL Formatting objects)로 구성되는 XSL(Extensible Stylesheet Language)를 제안하였다. 본 논문에서는 XML 문서와 XSL 스타일 시트를 이용하여 XML 문서의 데이터를 변환하고 XSL-fo 정보를 이용하여 결과 FO(Formatting Objects)를 생성한다. 또한 트리로 구성된 결과 FO에서 페이지 정보와 FOT (Formatting Objects Tree)를 추출하는 FOT 생성부를 두었고, 디스플레이 관리기와 포맷팅 모듈 객체 관리기를 두어 FOT를 포맷팅을 위한 모듈로 저장하고 디스플레이 해주는 포맷팅 처리 시스템을 설계 및 구현하였다.

본 논문에서는 저시력자의 개선된 독서 환경을 제공하는 시각보조기기를 위한 실시간 영상처리 SoC(System on Chip) 하드웨어 구조 설계에 대해서 기술한다. 기존의 시각보조기기는 화면 영상이 실제 움직임보다 늦게 출력되는 잔상 현상이 발생하며, 색 변환 기능도 제한적이다. 따라서 본 논문에서 제안하는 실시간 영상처리 SoC 하드웨어 구조는 데이터 연산을 최소화함으로써 잔상 현상이 감소되며, 저시력자를 위한 다양한 색상 모드를 지원한다. 제안하는 영상처리 SoC 하드웨어 구조는 Core-A 모듈, Memory Controller 모듈, AMBA AHB bus 모듈, ISP(Image Signal Processing) 모듈, TFT-LCD Controller 모듈, VGA Controller 모듈, CIS Controller 모듈, UART 모듈, Block Memory 모듈로 구성된다. 시각보조기기를 위한 실시간 영상처리 SoC 하드웨어 구조는 Virtex4 XC4VLX80 FPGA 디바이스를 이용하여 검증하였으며, TSMC 180nm 셀 라이브러리로 합성한 결과 동작주파수는 54MHz, 게이트 수 197k이다.

Recently, a drone is used for the general purpose application although the drone was builtfor the military purpose. A drone is actively used for the creation of contents, and an image acquisition. In this paper, we develop a 3D library module platform using 3D mesh model data, which is generated by a drone image and its point cloud. First, a lot of 2D image data are taken by a drone, and a point cloud data is generated from 2D drone images. A 3D mesh data is acquired from point cloud data. Then, we develop a service library platform using a transformed 3D data for multi-purpose uses. Our platform with 3D data can minimize the cost and time of contents creation for special effects during the production of a movie, drama, or documentary. Our platform can contribute the creation of experts for the digital contents production in the field of a realistic media, a special image, and exhibitions.

A XML Instance repository model based on the Edge-Labeled Graph is suggested for storing the XML instance in Relational Databases, This repository model represents the XML instance as a data graph based on the Edge-Labeled Graph, extracts the defined value based on the structure of data path, element, attribute, and table index table presented as database schema, and stores these values using the Mapper module, In order to support querry, XML repository model offers the module translating XQL which is a query language under XPATH to SQL, and has DBtoXML generator module restoring the stored XML instance. As a result, it is possible to represent the storage relationship between the XML instances and the proposed repository model in terms of Graph-based Path, and it shows the possibility of easy search of specific element and attribute information.

This paper describes a passive SID sensor tag that provide physical security functions based on a sensor interface module. It elementarily consists of a serial I/O interface, control module, and sensor module. In this paper, it show tamper-proof security functions by comparison and encryption with the sensor signal data using the physical resistors. The passive SID sensor tag can be realized by the real time management for the safety, forgery, and so on. The proposed SID tag embedded with a sensor module is expected to find wide physical security applications.

The transaction was happened within a single business entity or a single marketplace at the stage of e-business. It becomes to grow to complex form. Expecially, the need for business collaboration between business entities or marketplaces has being on the rise as the core topic. The format translation between documents is very important factor according to various the exchanged document formats. In this paper, we define ebXML as the basic format of exchanged document according to object-oriented business transaction. Also we design the multi-format translation system to support the translation of various document formats. The proposed system in this paper, is designed with model-driven method and it is possible to construct with various structure as for system environment. The proposed translation system is designed to use the proposed system as adding the corresponding parsing module even though any format of document. Also, we increase the reusability of data as using the common data set. In this paper, we prove the superiority of the proposed system to compare the performance with the legacy system for various format translation.

This paper describes the implementation of HTML converter for wireless internet access in wireless application protocol environment. The implemented HTML converter consists of the contents conversion module, the conversion rule set, the WML file generation module, and the frame contents reformatting module. Plain text contents are converted to WML contents through one by one mapping, referring to the converting rule set in the contents converting module. For frame contents, the first frameset sources are parsed and the request messages are reconstructed with all the file names, reconnecting to web server as much as the number of files to receive each documents and append to the first document. Finally, after the process of reformatting in the frame contents reformatting module, frame contents are converted to WML's table contents. For image map contents, the image map related tags are parsed and the names of html documents which are linked to any sites are extracted to be replaced with WML contents data and linked to those contents. The proposed conversion method for frame contents provides a better interface for the users convenience and interactions compared to the existing converters. Conversion of image maps in our converter is one of the features not currently supported by other converters.

최근 컬러를 취급하는 개인용 컴퓨터나 프린터, 스캐너, 디지털 카메라 등의 사용이 필수적으로 되고있다. 하지만 이런 입·출력 장치들은 제조사나 제품모델에 따라 색이 다르게 보여진다. 따라서 이런 입, 출력 장치의 색특성을 고려하여 맞게 영상신호를 보정함으로써 원래의 색에 가깝게 출력할 수 있는 색 관리 시스템(CMS)이 개발되고 있다 색 관리 시스템은 색 공간 변환 모듈과 색특성 데이터가 저장되어 있는 입.출력 장치의 ICC 프로파일들로 구성이 되는데 장치간의 색 일치가 성공적으로 이루어지기 위해서는 무엇보다도 장치의 색특성 데이터가 정확하게 저장된 ICC프로파일이 마련되어야 한다.
