Abstract:
The present invention relates to a golf club head. The golf club includes an iron, a wood, a wedge, a utility iron, a hybrid iron, a fairway wood and a hybrid. The golf club head includes: a head body (B) consisting of a face (F), a sole (S), and a back (BK) forming a back surface; a hosel (H) and a neck (N) for connecting the head body (B) to a shaft; and section modulus adjusting means for decreasing the cross-sectional surfaces of the hosel (H) and of the neck (N). The golf club head according to the present invention is configured such that the section modulus decreases during the process of transferring the impact applied to the head body (B) to the hosel (H), so as to microscopically improve the function of the golf club head as an elastic body, thus enabling the golf club head to absorb impacts as if a microscopic spring were interconnected between the head body (B) and the hosel (H), and thus absorbing and dispersing the impact being transferred to the hand of a golfer with the result that golfer's elbow is prevented, and damage to the shoulder joint, damage to the wrist joint, and damage to muscles may be reduced. Since the total weight of the neck (N) or of the hosel (H) decreases, the weight of the head body (B) should be increased so as to meet the prescribed total weight, and accordingly the increased weight of the head body (B) increases driving distance.
Abstract:
The present invention relates to a novel use of lignan compounds, which are isolated and purified from nutmeg or the aril of nutmeg for anti-wrinkle, and more particularly, the present invention relates to a novel use for anti-wrinkle of an extract of the nutmeg or an extract of the aril of the nutmeg, fragrin A, austobailignan 7, licarin E, and macelignan. The extracts and lignan compounds of the present invention have activities in suppressing collagen degradation enzyme- 1(MMP-I, matrix metalloprotei-nase-1) and formation of new collagen (type-1 procollagen), thereby having effect on inhibitng wrinkle caused by photoaging. Accordingly, the extracts and lignan compounds of the present invention may be useful for preventing or treating wrinkle caused by photoaging.
Abstract:
A protocol for a peer power save mode (PPSM) in a tunneled direct link setup (TDLS) wireless network and a system therefor are provided. A station (STA) set up a TDLS link can send a frame having a power management bit set to a peer STA to enter into a power save mode (PSM). In this case, the station entering into the PSM operates in a PPSM client mode. When the peer STA operates in the PPSM client mode, the STA can operate in the PPSM access point (AP) mode or can enter into the PPSM client mode. The STA operating in the PPSM AP mode buffers data for the STA operating in the PPSM client mode and informs the peer STA of information indicating that there is buffered data by the use of a peer traffic indication frame or the like. In principle, a U-APSD procedure can be applied to the transmission of data through a direct link from the STA operating in the PPSM AP mode to the STA operating in the PPSM client mode.
Abstract:
A procedure for selecting the best path from among a direct link setup (DLS) path and an access point (AP) path is disclosed. A method for selecting the best path by a first wireless station from among the DLS path and the AP path includes: receiving a first message, e.g., a path switch request message, comprising measured quality information of a link constituting the DLS path and/or a link constituting the AP path from a second wireless station, a counterpart of the DLS path; and determining whether to switch a data transmission path or a data reception path between the DLS path and the AP path by using the received measured channel quality information. Although there is no explicit request from the counterpart of the DLS link, the path switch request message including the measured channel state information of the DLS link and the link of the AP path is transmitted, so the wireless stations using the DLS service can acquire the channel state information of the links frequently to transmit data by using a path of better channel state.

Abstract:
The present invention relates to a foldable functional pillow which is composed of two pillow units foldable onto each other to enable users to select either pillow unit or use the pillow in a folded state to raise the height of the pillow. The pillow of the present invention has two pillow units (10, 20) which are formed into a single body and foldable centering from a bending portion (1). The pillow units (10, 20) have respective openings (11, 21) which are opposed to each other that are opened/closed by a zipper (2) at the side of the bending portion (1). The pillow units (10, 20) have interiors with respective head support members (12, 22), cervical vertebral support members (13, 23), and a plurality of support members including left support members (14, 24) and right support members (15, 25), which can be inserted through the openings (11, 21). Partitions (16, 26) are arranged at interfaces between the pillow units to prevent movement of the head support members (12, 22), cervical vertebral support members (13, 23), and left support members (14, 24) and right support members (15, 25.)
Abstract:
There is provided a protocol for a power save mode (PSM) in a direct link setup wireless network. In an aspect of the present invention, among first and second stations between which a direct link has been set up, the first station trying to enter the PSM transmits a request message, including schedule information necessary for communication with the second station, to the second station. The second station transmits a response message, including a status code indicating whether it accepts the schedule information or not, to the first station in response to the request message. If the status code indicates that the second station accepts the schedule information, the first station may transmit an MPDU whose power save bit is set to '1' to the second station and then enter the PSM. However, if the status code indicates unacceptability, modified schedule information may be included in the response message.

Abstract:
Disclosed is a method of analyzing a protein, and more particularly, a method of analyzing a protein, comprising the steps of: (A) labeling small amounts of the protein groups with CyDyes having different fluorescence properties, respectively; (B) mixing 50~100jUg of each of the protein groups, labeled in step (A), with l~5rag of each of one or more of the unlabeled protein groups, and subjecting the mixture to electrophoresis; (C) subjecting the electrophoresed gel to fluorescence analysis to detect a difference in protein distribution between the protein groups; and (D) excising spot(s), showing the difference in protein distribution, from the gel, and isolating and identifying a protein, which is different between the protein groups, from the spots. According to the present invention, a qualitative and quantitative analysis can be performed with a difference in the fluorescence of CyDye having very high sensitivity, and a protein can be identified using MALDI-TOF simultaneously while analyzing in a gel. Thus, the limitation of reproducibility can be overcome, and the time and cost for analysis can be remarkably reduced. Further, since two proteins can be simultaneously analyzed in a gel, the method can be effectively employed when two proteins are compared and analyzed each other, and then a protein is identified.
