Full time lecturer (Engineering College, Department of Computer Science and Engineering) at Chung-Ang University, Seoul, Korea, 2005

 Chung-Ang University is a major South Korean private university. The university's name means "center" or "central" in Korean. It carries an enrollment of over 25,000 students. As of 2003, the university claims to have graduated 117,511 holders of the bachelor's degree, 19,743 of the master's degree, and 2,935 of the doctorate. It has campuses in Seoul's Dongjak-gu and also in Gyeonggi province's Anseong City. The university traces its origins to 1918, when the Chung-Ang Methodist Church in Seoul opened a kindergarten. Beginning in 1922, a kindergarten teacher certification course was offered at the kindergarten.

 This developed into Chung-Ang Normal School , which was established in 1928. It became a women's junior college in 1945, and a full women's college in 1947. It became coeducational in May 1948. It was licensed as a university, one of the country's first, in 1953, at which time a graduate school was also opened. The second campus was established in 1979.


Post-doc position with prof. Pramod K. Varshney, Syracuse University, Syracuse, NY, 2004  

 Syracuse University (SU) is a private research university located in Syracuse, New York. The university is set on a mostly residential campus, which features an eclectic mix of buildings, ranging from nineteenth-century Romanesque structures to contemporary buildings designed by renowned architects such as I.M. Pei. The center of campus, with its grass quadrangle, landscaped walkways, and outdoor sculptures offers students the amenities of a traditional college experience. At the same time, since the university overlooks Downtown Syracuse, students can enjoy the social, cultural, and recreational opportunities of a medium-sized city. The school also owns a Sheraton Hotel and a golf course near campus, as well as properties in New York City, Washington, D.C. and a 30 acre (121,000 m²) conference center in the Adirondack Mountains of Upstate New York.

 Officially chartered in 1870, Syracuse traces its institutional roots back to 1832 when it was founded as a seminary by the Methodists. Syracuse University¡¯s undergraduate and graduate programs are highly regarded. The university is especially well known for its programs in the fields of public affairs, communications, creative writing, architecture, geography, information studies and Entrepreneurship.

 The university had a total 2005-2006 of 18,734 students: 12,905 undergraduates, 5,067 graduates, and 762 law students. 3 undergraduate students achieved national recognition by their selection as a Rhodes Scholar, Truman Scholar and Goldwater Scholar. Syracuse University is one of only 8 institutions in the country whose students have won all three of these honors in one year.

Research Areas Overview


Systems Assurance

 Systems Assurance focuses on the design, development, and deployment of information systems with a particular emphasis on networked systems, information assurance, information security, and information integrity. The emphasis on assurance, security, and integrity are motivated in part by recent findings such as the Report of the President's Commission on Critical Infrastructure Protection. This report cites the increased reliance and vulnerability of networked information systems used to control power, communications, and information infrastructures. The report outlines the critical need to design and deploy complex interconnected systems that are reliable, safe, and secure. Our research focuses on the ways information systems are designed to work reliably, safely, correctly, and securely. These methods also aim to reduce the complexity of systems assurance.


Networked and Distributed Computing

 The importance of networked computing and information retrieval is cited by many as crucial to the nation's information infrastructure. The challenge presented by this is the design, development, deployment, and assurance of complex systems in applications such as telecommunications, air traffic control, health care, mobile computing, and electronic commerce. These are critical and expensive systems. They rely on a collection of switching systems, databases, network protocols, scheduling and routing algorithms, distributed hardware, and concurrent software. These systems must work correctly and economically with guarantees of performance, availability of service, safety, and security. This is an area of tremendous federal and industrial need and the funding opportunities are expected to be high, as are the job market demands for students. This defines the scope of the focus area in Trusted Real-Time Networked Computing. More specifically, the engineering challenges in this area include high performance protocols, architectures, and algorithms; design of concurrent systems of hardware and software; assurance of performance in real time; testing and performance evaluation; assurance of correctness, availability, integrity, and security; multimedia system and technologies; databases and information retrieval; and heuristic search and optimization algorithms.


RF and Wireless Information Systems

 The area of RF and Wireless Information Systems brings together specializations such as communications, microwaves, antennas, and signal processing to solve problems that are challenging because of their magnitude, level of difficulty, and projected industrial impact. The objective of this area is threefold. One of the goals is to integrate the various faculty members in the electrical engineering program and then gradually link with faculty members in the other two programs who are interested and would like to participate in this initiative. The second goal is to prepare for the education and research of the next century since, according to many authorities, we are going to build an "Internet in the Sky" and according to some estimates predict that "we will spend 50 billion dollars by the turn of the next century to build and launch new satellites--and twice that for antennas, phones, switches, and other gear. 


Applied Computing

 The applied computing area focuses on targets of opportunity that fall outside the scope of the other research areas. Much of what is done in this area currently falls into molecular electronics. Molecular electronics is an emerging and highly cross-disciplinary field, which lies at the interface of molecular physics, material science, biophysics, electrical and optical engineering, as well as computational science. Molecular electronics involves the encoding, processing, and retrieval of information at a molecular level, as opposed to the current semiconductor techniques in which the above functions are achieved via miniaturization of bulk devices. Therefore, molecular electronics suggests a fundamentally new concept in device miniaturization and operation.

IBM 5250

From Wikipedia, the free encyclopedia

Jump to: navigation, search

 IBM 5250, originally, was a particular model of a terminal device sold with the IBM System/34 minicomputer system. Similar to the IBM 3270, it is a block-oriented terminal protocol, yet is incompatible with the 3270 standard. The relationship between the terminal and system was rich: The system sent a data stream containing markup bytes indicating the boundaries of data entry fields, highlighted or colored areas, and indication that the system was busy responding to the last request from the terminal. The 5250 data stream definition has been refined over time to include GUI elements like pop-up windowing, check and option boxes, mouse handling, and pull-down menus.

 The term "5250" now refers to the content of the data stream itself; few physical 5250 terminals still exist, although they are still used to provide a "connection of last resort," hard-wired to the host computer. Robustly constructed, 5250 terminals weighed roughly 36kg (80 lbs.) Today, it is more common to use PC or web-based terminal emulation packages that can interpret and display 5250 data streams. Two commonly-used emulators are IBM's own iSeries Access and TN5250, an open source project.

 A number of modern 5250 emulaton packages include additional features beyond displaying the data stream; for example, IBM's iSeries Access includes support for graphical system administration, remote system console connectivity, file transfers, macros, printer emulation, and support for client-server database connectivity.



 Informix currently provides two kits to interface an Informix database with the Web by writing CGI programs in Informix ESQL/C or the Informix 4GL. Both contain collections of functions as well as example programs. In addition to the interface kits, Informix has partnerships with Netscape, Spider Technologies Inc., and Silicon Graphics Inc.'s WebFORCE Web server and software systems.  



 Illustra Information Technologies markets an object-relational DBMS server that can be extended to support new data types and functions using plug in modules called DataBlades. (See "Object-Relational Hybrids," in the July 1995 issue of DBMS, page 46.) Illustra released a beta version of its first Web DataBlade in March 1995. The Web DataBlade adds a new base data type called an anchor to the Illustra server. An anchor maps an HTML hyperlink to an object in an Illustra database by associating an Illustra data type with a rendering program (Mosaic or a multimedia player application). The DataBlade lets Web browsers initiate SQL queries, and it also formats the query results as HTML pages, including support for HTML tables. Illustra used its Web DataBlade to create a searchable version of the DBMS Buyer's Guide.

 By the end of 1995, Illustra expects to begin shipping version 2 of its Web DataBlade. This will introduce new HTML tags that let developers embed SQL queries in HTML pages. A function added into the Illustra server by the DataBlade will handle parsing of the SQL tags and formatting of results into HTML pages. No CGI program will be required for this phase, so version 2 promises to perform faster and be simpler to implement. It should also be more secure than a CGI script interacting with the database. Illustra's future plans include support for Java.
