An objective of the present invention is to provide a method of producing artificial bio-soil aggregates based on foamed concrete for plant growth that can ensure sufficient moisture and plant nutrients for the habitat of plants in non-soil conditions; obtain a lightweight, durable, and deep soil layer, and continuously provide a favorable environment for plant growth. To achieve the above objective, according to the present invention a paste is prepared by mixing cement with an admixture, such as ochre and burnt-furnace slag; foamed concrete is formed by adding foam bubbles with an appropriate foaming rate to said paste, thereby producing soil concrete. When the foamed concrete is used, a designated compressive strength can be ensured and a number of pore spaces are formed, which allow the air to be sucked and expelled therethrough and store moisture therein. Also, hydrogel that is incorporated into the foamed concrete may supply nutrients required for plant growth, improve pest resistance, and store and supply a large amount of water.

A method for receiving signaling information in a digital broadcast system according to an embodiment of the present invention comprises: a step of receiving a plurality of frames in which signaling information of a second layer is inserted in a signaling area of a first layer or a packet of a first layer; and a step of determining the signaling information of the second layer from the signaling area of the first layer or the packet of the first layer, and receiving service data using at least one of the determined signaling information of the second layer and pre-stored signaling information of a second layer.

The present invention relates to a method for transmitting signaling information in a digital broadcast system, the method comprising the steps of: adaptively generating a signaling table relating to signaling information transmitted from a data link layer on the basis of at least one structure among a hierarchical structure and a flat structure on the basis of a characteristic of service configuration; and transmitting the generated signaling table.

An audio metadata providing apparatus and method and a multichannel audio data playback apparatus and method to support a dynamic format conversion are provided. Dynamic format conversion information may include information about a plurality of format conversion schemes that are used to convert a first format set by an author of multichannel audio data into a second format that is based on a playback environment of the multichannel audio data and that are each set for corresponding playback periods of the multichannel audio data. The audio metadata providing apparatus may provide audio metadata including the dynamic format conversion information. The multichannel audio data playback apparatus may identify the dynamic format conversion information from the audio metadata, may convert the first format of the multichannel audio data into the second format based on the identified dynamic format conversion information, and may play back the multichannel audio data in the second format.

The author explored the factors that affect user's acceptance of Facebook by analyzing data provided in a survey of Facebook users (n = 346) using hypotheses based on the Technology Readiness and Acceptance Model (TRAM). In addition, he investigated the role of a revised TRAM on social capital building. Results showed statistically significant support for the hypothesized model, indicating that positive and negative technology readiness (PTR and NTR) play an important role in the formation of perceived ease of use (PEOU), perceived usefulness (PU), and perceived playfulness (PP) as well as in generating the intention to continue using (ICU) Facebook and social capital building. However, NTR did not significantly affect PP. The study also showed that ICU Facebook was mediated by users' PEOU, PU, and PP, and that social capital building was mediated by ICU Facebook. Theoretical and practical implications and limitations are discussed. © 2013 Elsevier B.V.

A printed wide-slot antenna with a parasitic patch for bandwidth enhancement is proposed and experimentally investigated. A simple 50-Ω microstrip line is used to excite the slot. A rotated square slot resonator is considered as reference geometry. The rotated square slot antenna exhibits two resonances (f 1: lower resonant frequency, f 2: higher resonant frequency). By embedding a parasitic patch into the center of the rotated square slot, the lower resonant frequency f 1 is decreased and the higher resonant frequency f 2 is increased. Thus, broadband characteristic of the wide-slot antenna is achieved. The measured results demonstrate that this structure exhibits a wide impedance bandwidth, which is over 80% for S 11 ≤ -10dB ranging from 2.23 to 5.35 GHz. Also, a stable and omnidirectional radiation pattern is observed within the operating bandwidth. In this design, a smaller ground plane is considered compared to the reference antenna (rotated square slot antenna without the parasitic center patch). © 2012 IEEE.

A printed microstrip-fed monopole ultra-wideband (UWB) antenna with triple notched bands is presented. By embedding a modified H-shaped resonator with an additional outer line beside the microstrip feedline, band-rejected filtering properties around the 3.5 GHz WiMAX band, the 5.2/5.8 GHz WLAN band, and the X-band satellite communication band are generated. The notched frequencies can be adjusted according to specification by altering the modified H-shaped resonator. Sharp gain reductions occur at 3.7, 5.2, 7.5, and 7.9 GHz. However, for other frequencies outside the notched bands, the gain is stable in the entire UWB band. © 2012 IEEE.
