Abstract:
A quality of service (QoS) securing apparatus and method using a communication protocol is provided. The QoS securing method is performed by a reception side that is receiving data from a transmission side. The method includes generating information about a changed communication environment according to a change in a communication environment of the reception side, and transmitting the information to the transmission side. An exchange of information about a communication environment using the communication protocol between the reception side and the transmission side can inform the transmission side about resources of the reception side, link characteristics, characteristics of a link on a transmission path, etc., thereby securing a QoS of data communication between the reception side and the transmission side.
Abstract:
A method of adjusting quality of service (QoS) with respect to changes in a transmission environment of a mobile terminal receiving data based on a stream control transmission protocol (SCTP) session. When the transmission environment of the mobile terminal receiving data based on the SCTP session changes, the mobile terminal transmits link information indicating a new transmission environment to a destination node, and the destination node adjusts the quality of data or the size of a transmission window based on the link information. Thus, without adding separate network devices, the QoS of the data being transmitted can be adjusted with respect to the changed transmission environment, only by adding functions with software to the transmission terminal and the reception terminal. Also, since the destination node manually adjusts the transmission window according to the link information, packet loss can be minimized compared to the conventional congestion control method.

Abstract:
A method of and apparatus for constructing a user profile using a content tag, a method of recommending digital content by using a user profile including a tag included in the digital content and a preference value for the tag. According to the methods and apparatus, a user profile is generated by using a content tag, and thus the taste of the user according to digital content consumption can be expressed in more varied ways. Also, by suggesting a method of generating a tag from web content, construction of a user profile for digital content having no tag is enabled. Furthermore, a tag extracted from digital content used by a user is included in a profile and it can be used for a variety of purposes, such as expansion of a comparison scope, use of preference keywords, providing of content links, and expansion of search scope.

A method comprising transforming Schizosaccharomyces pombe with a deletion cassette, constructed by four-round serial PCR, block PCR or total gene synthesis, containing a homologous recombination site is provided for preparing gene-targeted heterozygous deletion Schizosaccharomyces pombe. Also provided are gene-targeted hetero2ygous deletion Schizosaccharomyces pombe mutants prepared by the method, and a library of gene-targeted heterozygous deletion Schizosaccharomyces pombe mutants. Further, the library is useful in constructing a method and a kit for screening a drug's modes of action.
Abstract:
Methods of forming integrated circuit devices include forming a field effect transistor having a gate electrode, a sacrificial spacer on a sidewall of the gate electrode and silicided source/drain regions. The sacrificial spacer is used as an implantation mask when forming highly doped portions of the source/drain regions. The sacrificial spacer is then removed from the sidewall of the gate electrode. A stress-inducing electrically insulating layer, which is configured to induce a net tensile stress (for NMOS transistors) or compressive stress (for PMOS transistors) in a channel region of the field effect transistor, is then formed on the sidewall of the gate electrode.
