선용품공급업은 선박수리업, 유류공급업과 함께 항만 부가가치를 창출하는 대표적인 산업 중 하나이다. 2019년 기준 항만별 선용품 거래 건수를 살펴보면, 연평균 15.0%의 증가율을 보이고 있다. 특히 부산항의 비중이 49.6%로 가장 높게 나타나며 울산(12.7%), 인천(6.1%), 평택(4.7%) 순으로 높게 나타나고 있으며 지속적으로 성장하는 추세이다. 허나 선용품 수발주 체계를 분석해 보면····(중략)····

최근 조선해양산업의 트렌드는 해양플랜트 육성과 친 환경 녹색선박과 에너지 절감기술이라는 두 가지 방향으로 진행되고 있다. 조선해양산업의 메가트랜드인 해양플랜트와 친환경 선박 기술력을 확보하고, 국가의 주력산업으로 세계적인 경쟁력을 지니기 위해서 가장 근본적으로 지원이 필요한 부분은 관련된 다양하고 양질의 정보를 시의 적절하게 산업의 주체들에게 제공해주어야 한다. 따라서 본 연구는 조선해양기자재 정보센터의 필요성을 바탕으로 정보센터가 어떠한 기능에 우선순위를 두어야 하는지 분석하는 것을 목적으로 한다. 이 연구의 분석 결과는 조선해양 정보센터 기능 및 조직체계에 반영될 수도 있고, 정보센터 설립의 타당성을 분석하는 의사결정의 방법으로 활용될 수 있을 것이다.

수리조선산업은 기술 및 노동집약적 산업으로 기계, 철강, 전기전자, 화학 등 연관산업에 대한 생산 유발효과 및 고용효과가 높은 산업이다. 또한 연계 산업에 대한 직접적인 생산증가 효과와 선원 체류에 따른 부가가치 증가 등의 부수효과를 함께 고려할 때 지역경제에 대한 기여도가 높은 산업적 역할을 수행하고 있으며, 특히 부산 경남 울산 지역은 세계 5위권 전후에 해당하는 해운물동량을 처리하는 입지조건과 신조선 분야 1위의 우수한 기술 및 노동력을 보유하고 있다. 이러한 긍정적인 측면에도 불구하고 여러 요인들로 인해 수리조선산업이 경쟁력이 확보되지 못하고 있는 실정이며, 2013년 들면서 부산항의 컨테이너 물동량 실적이 7위로 하락하고 있는 실정이다. 따라서 본 연구에서는 부산항을 중심으로 수리조선산업 공급망 관리를 위하여 정보화 네트워크 구축사례를 분석하고, 이를 통하여 수리조선산업 정보화 네트워크의 성공적인 구축 방안을 모색하고자 한다.

This study was conducted on Yuanming New Garden in China, which re-lighted the previously lost or damaged original space through representation from the perspective of creating traditional landscape. We looked at the composition of this place, the comparison of relevant literature and actual representation, and the characteristics of representation techniques. The results are as follows. First, TYuanming New Garden is a representation space with the motif of Yunamingyuan in Beijing. An advisory group of some 400 related experts discussed the prototype. The historicity of the real space was considered in the representation process. Second, New Yuanmingyuan garden was recreated based on the 'The Forty Scenic Views of Yuanmingyuan', and 31 of the scenic spots were created. The buildings in each precinct had a 1:1 scale response with structures that were previously constructed in Yuanmingyuan, Beijing. New Yuanmingyuan garden's way in which the main landscape is laid out around the Fuhai Lake(福海), which the landscape is drawn appeared was the same as Yuanmingyuan in Beijing. However, some of the facilities were reproduced on the basis of the 'The Forty Scenic Views of Yuanmingyuan', so they turned out to be different from what Yuanminyuan in Beijing looks like today. New Changchunyuan garden was represented around water landscape of the Western Mansins(Xiyang Lou, 西洋樓) area and the Haeakgaegum(海岳開襟), and the buildings and the facilities were reconstructed based on the 'Copper Print of Western Mansins'. Third, Yuanming New Garden made a prototype of the 'The Forty Scenic Views of Yuanmingyuan' and 'Copper Print of Western Mansins' during the process of synchronic changes in the garden. In addition, the original space and the ambiguous original space or exhibition space were clearly identified through the plant. On the other hand, due to the reenactment of buildings, the spatial composition and placeability of the original spaces of Yuanmingyuan garden and Changchunyuan garden in Beijing were not inherited, and the introduction of elements that did not match traditional landscaping spaces, and the introduction of garden elements that were not prototype and other variations for the use of tourism were found to be drawback.

Stress relaxation tests have been performed under five different tensile strain levels and five different bending strain levels. Three different theoretical models have been developed based on four-element Burger's model, viscoelastic theory and viscous-viscoelastic theory. Experimental data were used to obtain parameters of the models and to verify accuracy of the models. Among the three theoretical models developed in this study, three-integral model (Model 3) based on viscous-viscoelastic theory showed the most exact estimations of stress relaxation under both tensile and bending strains and their correlation coefficients were greater than 0.99 for all the strain levels. Model 1 showed little initial stress relaxation. Model 2 showed excessive initial relaxation and, then, no relaxation after about 20 minute of strain application. Stress retention under strain decreased as strain increased, which means increased stress relaxation as strain increases. When the strain level was less than proportional limit, the effect of strain level on stress relaxation was not clearly shown. However, this effect was increased as strain level increased when strain level was greater than proportional limit.

Tripitaka Koreana in Haein Temple, Hapcheon Province is the most historical and largest heritage in this country, however the species of their blocks have yet been unknown. A nondestructive test method is necessary to investigate their species. The oven-dry density of wood was measured by inversely using the principle of high frequency moisture meter. The oven-dry densities of more than 100 domestic species of specimens estimated by measurement method and high frequency moisture meter were compared and following conclusions were obtained. There was highly close correlation between the oven-dry density estimated by measurement method and the oven-dry density estimated by high frequency moisture meter. The densities of Tripitaka Koreana that was a global cultural heritage could be correctly estimated by using high frequency moisture meter and the equilibrium moisture content under which Tripitaka Koreana equilibrated, thus, it was expected to provide the key to species identification.

This study was carried out to clarify the mechanical behaviour of the earlywood and the latewood to the compressive load applied parallel to the grain. The results from the analysis of Japanese cedar wood (Cryptomeria japonica) were used to introduce a concept on stress-strain behaviour of the earlywood and the latewood. There was a significant differences in the mechanical behaviour of the earlyWood and the latewood. In the earlywood, the rate of cell wall upon annual ring was almost similar and the strain increased linearly with the stress increased. However, the rate of cell wall upon annual ring varied in the latewood and the strain of that increased curve-linearly with the stress increased. The longitudinal compression modulus of elasticity (MOE) variation by loading speed on latewood specimens and earlywood specimens shows no significant difference. The modulus of rupture (MOR) and MOE of latewood were about 4 times higher than those of earlywood.
