In this paper, we implemented a terrestrial/cable PSIP converting system, so-called a PSIP converter, which is converting a terrestrial PSIP into a cable PSIP for a data broadcasting service in the interoperable network of terrestrial and cable, and define an interface between the PSIP converter and the OOB SI generator by using PMCP messages compliant to ATSC T3/Sl. The exiting PSIP converter just converts a terrestrial PSIP into a cable PSIP compliant to ATSC and OCAP standard and transmits by a MPEG-2 TS format. That is to say, it is not for the digital data broadcasting but for the digital broadcasting. In addition, the PSIP converter can support various types of PSIP information to the OOB SI generator by using PMCP messages defined by a hierarchical structure as per each channel, audio/video event, data event and so on.

Poultry manure compost (PMC) as the organic fertilizer sources has a high nutrient content such as nitrogen, phosphate and potassium, and its properties been affected by bulking agent. This study was conducted to evaluate properties of mixed organic fertilizer (MOF) containing PMC composting with sawdust and peat moss as bulking agent, and to measure a characteristics of plant growth by their application. The MOF containing 10~30 % PMC had a coincidency with its guideline in Korea. As applied with MOF containing PMC composting with sawdust (PMCS) or MOF containing PMC composting with peat moss (PMCP), dry weight of plant was increased in MOF treatments blending with 10~30 % PMCS or 10~30 % PMCP. In correlation coefficient between blending ratio of PMC in MOFs and plant growth indexes, PMCS was not significantly different, but its PMCP a positive effect (P<0.05). These results indicated that PMC was able to blend about 10~30 % as mixed organic fertilizer source, and its application increased in plant growth.

In this paper, we propose a method for constructing terrestrial/cable PSIP converting system, so-called a PSIP converter, which is converting terrestrial PSIP into cable PSIP for a data broadcasting service in the interoperable network of terrestrial and cable, and define an interface between the PSIP converter and the OOB SI generator by using PMCP messages compliant to ATSC T3/S1. The exiting PSIP converter just converts terrestrial PSIP into cable PSIP compliant to ATSC and OCAP standard and transmits by a MPEG-2 TS format. That is to say, it is not for the digital data broadcasting but for the digital broadcasting. Say in other word, the proposed PSIP converter is designed to convert and transmit PSIP including DET information which is necessary data event information for data broadcasting service. In addition, the PSIP converter can support various types of PSIP information to the OOB SI generator by using PMCP messages defined by a hierarchical structure as per each channel, audio/video event, data event and so on.

This experiment was conducted to investigate nutrient leaching and mobility through soil column for application of biochar pellet during rice cultivation. For nutrient leaching through soil column experiment, it was also consisted with four treatments as control, 100% of pig manure compost pellet (PMCP), biochar pellet (pig manure compost:biochar, 6:4)(BP), and slow release fertilizer (SRF). For experimental results, it was observed that $NH_4-N$ concentration in the leachate was gradually decreased at pick of 35 days and $NO_3-N$ concentration was highest from 60 to 98 days after transplanting. $PO_4-P$ concentration in the leachate was shown to be lowest in the PMCP and BP. K concentration in the leachate was highest in the control, but lowest in SRF. For mobility of nutrient in soil depths, it shown that $NH_4-N$ concentrations were highest from 40 to 60cm and did not significantly different among treatments except the control. It was observed that the deeper depth, the higher concentration for $NH_4-N$ concentrations, but for $PO_4-P$ concentrations the deeper depth, the lower concentration. And also $PO_4-P$ concentration was highest in the control. For K mobility in soil, its pattern was appeared to be approximately same between the control and PMCP, and between BP and SRF. Therefore, it might be potential to be applied biochar pellet to reduce mobility of plant nutrients for rice cultivation.
