Hanok recently is getting attention by Korean wave and the eco-friendly construction. However it has the not a few . weak points to live in modem and been recognized as a big problem such as efficiency problem, hight cost to construct and maintenance difficulty to be solved. The solution are the modularity and weight lightening of Hanok but the roof is one of the most difficult parts of it, the roofrepresents the beauty of Hanok with graceful catenary line, filling timber and soil should be improved to the modem materials and construction methods as an alternative. As the result, this study conceives the improvement figuring out the problem and the case study review as well as suggests the valuation of feasible plan and the potential for modularity by application of the actual field. The roof is consisted of the framework as the constructable role on the upper part of roof board, the insulation and air layer as well as additional roof board should be installed to make easy the roof construction and attach the vapor permeability water proofed paper. Accordingly, Additional rafter, Diaphragm board and Panel can be used as the alternatives. and this reports the possibility of workability, modularity applied in the field. The results of this study are expected to improve the efficiency of the waterproofing of roofs, insulation, maintenance, etc and so on contribute to the pervasiveness of the hanok.

To define whole genome-level of structural variation by ionization energies and radiation doses in plant, the seeds of Ilpum rice cultivar were acutely irradiated with gamma rays (100Gy, 200Gy, and 400Gy) and ion-beams (20Gy, 40Gy, and 80Gy), respectively. Six M1 rice plants were re-sequenced by Hi-Seq2500 with Ilpum cultivar as control. The average sequencing coverage of the individuals was 10.6X, and the average mapping rate to the rice reference genome (IRGSP-1.0) sequence was 96.95%. The individual plants were irradiated with gamma-400Gy and ion-50Gy had highest variation of SNP with 471,837 and 469,147, respectively. The number of insertion/deletion was 77,500 and 77,106, the synonymous and frame-shift were 7,859 and 7,763 in above two individuals. Although high genome variation shown between Ilpum cultivar and irradiated individuals, there were non-correlation between number of variation and radiation doses. However, five individuals, except ion-20Gy, showed 33 common variant blocks (CVBs) spanning 6 Mb in whole rice genome (1.6%). The CVBs were distributed on 12 rice chromosomes, Chromosome 6 had biggest CVB (5 blocks, 1.3Mb), whereas chromosome 9 had smallest CVB (0.01Mb). Total five hundred fifty one genes were in CVBs which can regard radiation sensitive genes or may be regarded as radiation hot spots in rice genome. This study will contribute to the improvement of the radiation mutation breeding research in genetic and genomic aspect.
