Publication number: 20240082345Abstract: Provided is a peptide composition for preventing or treating Alzheimer's dementia. A peptide or a salt substituent thereof according to the presently claimed subject matter exhibits effects such as suppression of LPS-mediated cytokine production, suppression of LPS-induced neuroinflammation, amelioration of cognitive impairment, suppression of beta amyloid or tau protein aggregation, and suppression of neuronal loss. The polypeptide or the salt substituent thereof can permeate the blood-brain barrier, and thus, is expected to be usefully used for preventing or treating Alzheimer's dementia.Type: ApplicationFiled: August 25, 2021Publication date: March 14, 2024Applicant: HLB SCIENCE INC.Inventors: Yeong Min PARK, Wahn Soo CHOI, Seung-Hyun LEE, In Duk JUNG, Yong Joo KIM, Seung Jun LEE, Sung Min KIM, Mi Suk LEE, Hee Jo PARK, Seung Pyo CHOI, Minho MOON, Soo Jung SHIN, Sujin KIM, Yong Ho PARK, Jae-Yong PARK, Kun Ho LEE

Patent number: 11916831Abstract: A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.Type: GrantFiled: February 2, 2023Date of Patent: February 27, 2024Assignee: Electronics and Telecommunications Research InstituteInventors: Hee Soo Lee, Tae Gyun Noh, Jae Young Ahn, Kyoung Seok Lee, Young Jo Ko

Publication number: 20140344458Abstract: A load distribution device that distributes load of a target server is provided. The load distribution device includes a load detection unit that monitors a load amount of the target server and determines whether the load amount exceeds a predetermined critical value, a server driving unit that drives a replication server when the load amount exceeds the critical value, and a server control unit that distributes part of load to the replication server when the replication server has started to be driven. The replication server is implemented by a cloud computing technique.Type: ApplicationFiled: May 14, 2014Publication date: November 20, 2014Applicant: Korea University Research and Business FoundationInventors: Hee Jo Lee, Rashad Aliyev, Dong Won Seo, John Milburn

Patent number: 8200147Abstract: A wireless communication system for geographically controlling a communication area includes an access point for communicating with a terminal in a first area, and a jammer for generating noise for intercepting communication between the access point and a terminal in a second area. A jamming boundary for dividing an area in which the terminal can communicate with the access point and an area in which the terminal cannot communicate with the access point in an area in which the first area and the second area are overlapped is formed, and the jamming boundary is formed by a ratio between power of a signal transmitted to the terminal by the access point and power of a signal of the noise.Type: GrantFiled: November 25, 2009Date of Patent: June 12, 2012Assignee: Korea University Industry and Academy Collaboration FoundationInventors: Hee-Jo Lee, Yu-Seung Kim, Hyogon Kim

Publication number: 20090328138Abstract: A method and system for implementing activity-oriented access control (AOAC) to hospital information is disclosed. An access request device sends user credentials attaching user attributes to an AOAC server, which in turn searches activity rules that are assigned to user attributes from an activity server and a current work situation of the user from an activity recognition server. The AOAC server transmits an access request list corresponding to the activity rules and the current work situation of the user to the access request device so that it can select a desired access request among the list.Type: ApplicationFiled: June 30, 2009Publication date: December 31, 2009Inventors: Sung-Young Lee, Young-Koo Lee, Hee-Jo Lee, Xuan Hung Le

Publication number: 20080285468Abstract: In a session initiation protocol (SIP) corresponding to one of protocols for the voice over Internet protocol (VoIP), an exception detection module acquires a packet for session establishment. If each of fields of the header of the packet is out of a defined character length and includes at least one prohibited character, the exception detection module discards the packet. The exception detection module confirms a state of the session. If the packet is acquired more than a predetermined number of times in the state of the session, the exception detection module considers the packet to be abnormal and discards the packet.Type: ApplicationFiled: March 7, 2008Publication date: November 20, 2008Inventors: Dong-Won Seo, Hee-Jo Lee

Patent number: 7440406Abstract: An apparatus for displaying network status includes a network traffic collection unit, a network status display unit and a first attack type determination unit. The network traffic collection unit analyzes packets collected from an external communication network, and outputs connection information including a source Internet Protocol (IP) address, a destination IP address and a destination port number. The network status display unit receives the connection information transmitted from the network traffic collection unit for a predetermined period, and displays the connection information in a coordinate point data form on a three-dimensional rectangular coordinate system whose three axes are assigned to a source IP address, a destination IP address and a destination port number, respectively.Type: GrantFiled: December 29, 2004Date of Patent: October 21, 2008Assignee: Korea University Industry & Academy Cooperation FoundationInventors: Hee-Jo Lee, Hyo-Gon Kim, Sae-Woong Bahk

Publication number: 20070044147Abstract: A network monitoring apparatus collects packets of a first network, and generates visual information by displaying the packets on a parallel coordinate system which has one or more parallel axis for parameters of the packets. The network monitoring apparatus may extract attack packets from the packet, and the network monitoring apparatus may transmit the visual information to a remote server. Through the network monitoring apparatus, the network manager can visually grasp the state of the network or the existence of a network attack.Type: ApplicationFiled: January 3, 2006Publication date: February 22, 2007Inventors: Hyun-Sang Choi, Hee-Jo Lee

Publication number: 20050240989Abstract: The present invention is devised to solve the problem in which a state cannot be kept track of because an outgoing traffic and an incoming traffic pass through different firewalls on a Multiple Entry/Exit Point (MEP) network having a plurality of entry points. In the present invention, firewalls physically remote from each other can share connection information using a modified SYN cookie, so that stateful inspection firewalls physically remote from each other can be used even on the MEP network.Type: ApplicationFiled: April 23, 2004Publication date: October 27, 2005Applicant: SEOUL NATIONAL UNIVERSITY INDUSTRY FOUNDATIONInventors: Jin-Ho Kim, Sae-Woong Bahk, Hee-Jo Lee
