This study investigated the organizational system and policy for climate change adaptation in the USA, the UK, Australia, Germany and Japan. Based on the cases of foreign countries, the efficient policy directions for our climate change adaptation was discussed in this study. The national climate change adaptation can be improved by inter-ministerial working group, governance operating system by central government initiative, and Top-Down & Bottom-Up approaches between government and local community. The supervisory committee on climate change adaptation activity may be necessary for efficient policy enforcement and appropriate response to environmental changes. Also, the local adaptation pathways program and reporting adaptation evaluation may contribute to the consideration of local community in the national adaptation evaluation on climate change.

Laser Additive Manufacturing Directed Energy Deposition (LAM-DED) technology is a promising process for the maintenance and repair of ductile cast iron components. LAM-DED can produce high quality results compared to conventional welding processes. This is due to a narrow and specific heat-affected zone (HAZ) and a strong inter�face between the base material and filler, caused by reduced heat input with the high energy density. This method al�so maintains the composition of the clad material in the repair zone and deposits small volumes of filler in specific areas. This paper presents a succinct review of metallic powder alloys as cladding materials for the repair and main�tenance of cast iron components. It introduces commercial additive manufacturing (AM) powders used as filler ma�terials for laser cladding of cast iron components, discussing the evolution in microstructure, phase transformation, mechanical properties, and processing issues. This paper summarizes LAM-DED of AM powders for cast iron com�ponents and will be a helpful reference for researchers and industry professionals.

Through this thesis we have looked into the connection between Jae-Hyun Lee's life, character, poetics maintaining poetic point of view, and main trend of poetic circles. Though the matter how to connect writer's character, literary thought and literary works is under discussion in literary criticism, correct comprehension writer -who is subject of cognition and figuration- is necessary for rightful explication literary works. The summarized outline of this thesis is as follows. As seeing his life, Jae-Hyun Lee had passed "Kwagŏ(科擧)" when he was 15 years and had been in the government service for more than 60years. He was a wise subject with a great ambition to educate roles as faithful subjects and also in humble way he always searched his conscience to be a devoted subject. In poetics he tried to create a new meaning of poem, use elegant poetic words and deep meanings veiled in face words. In those days Koryo was obeyed in Yuan(元) therefore his political ability remained faithful for Koryo's restoration to the last. This attitude was revealed through a lot of poems including historical poems. Domestically, he truly loved people and searched for the way to save the people from distress moreover he felt sympathy simple and true emotion of people so that he wrote ‘Soakbu(小樂府)’. Looking into the stream of poetic world, spirits of patriotism, nostalgia, filial duty, actuality criticism, loving people and naturalism are dominant over all the others. As stated above his poetic world it is enough to find out that Jae-Hyun Lee was a great master and a pioneer of Korean Chinese poetry.
