디자인 컨설팅은 고객기업에 대한 총체적 조망을 바탕으로 통합적 관점에서의 디자인 해결안을 제시하는 의사결정 활동으로 정의할 수 있다. 이 같은 특성상 디자인 컨설팅 분야는 디자인 분야 외에도 프로젝트와 관계되어 있는 타 분야와의 긴밀한 협업관계 구축 및 유지관리가 프로젝트 성공에 있어 매우 중요한 변수로 작용한다. 이에 따라 분야 간의 협업을 지원해줄 수 있는 체계화된 프로젝트 수행 플랫폼의 필요와 중요성이 점점 대두되고 있다. 본 연구는 현재 디자인 컨설팅 수행에 널리 활용되고 있는 신제품의 전략적 개발을 위한 디자인 컨설팅 프레임워크에 웹의 기능과 기술적 특징을 접목하여 온라인 환경에서 디자인 컨설팅이 효율적으로 수행될 수 있는 시스템을 구축하기 위한 목적으로 수행되었다. 본 연구에서는 웹의 기술적 특성이 고려된 디자인 컨설팅 프로세스를 정의하고 각 컨설팅 단계별 수행 모듈들의 구체적 기능과 수행과제들을 규명하였으며 웹 기반의 디자인 컨설팅을 지원하는 온라인 통합 시스템의 구조를 제안하였다. Design consulting can be defined as the decision-making activity which suggests design solution with the integrated view in the whole comprehensive perspectives of the client. The success of design consulting project depends on how to build and keep up the deep cooperation between design and other related areas seriously. Due to this the importance and the necessity of the systematic platform to support the cooperation between many different areas for carrying out consulting projects are getting increased. The study is aimed to build the web-based system to support the efficient design consulting fulfillment online. The study defined the design consulting process which applied the technical attributes of web and suggested detailed work modules and the structure of the web–ased design consulting system.

A huge number of greenhouse soils in Korea have accumulated mineral elements which induce many nutritional and pathological problems. The present study was performed to the effects of the reduced fertilization on plant growth, and uptake and partitioning of minerals (N, P, K) and soluble carbohydrates using highly minerals-accumulated farmer’s greenhouse soil. On the basis of the recommended application for tomato crop, the application rates of N, P and K were 110(50%)-5.2(5%)-41.5(35%)kg ha<SUP>-1</SUP>, respectively, using Hoagland’s nutrient solution. Tomato growth rates during the whole experiment were not significant between treatments, but it was found that a decrease in daily growth represented after 60 days of treatment (DAT). The reduced application led to a drastic decrease in the concentration of N, P and K in fruits, and, thus, this resulted in lower uptake after 40 DAT. The lower phloem export and utilization of soluble carbohydrates caused an accumulation of extra-carbohydrates in leaves, stems and fruits in the reduced application. The reduced fertilization induced the capture of N, P and K in leaves and of soluble carbohydrates in stems compared to the conventional application. In this study, we suggest that it is possible to delay the first fertigation time in minerals-accumulated soils without an adverse impact on crop growth, but it is necessary to regularly monitor mineral status in soil to ensure a balanced uptake, synthesis and partitioning of minerals and carbohydrates.

On the basis of the recommended application for tomato crop, the application rates of N, P and K were 110(50%)-5.2(5%)-41.5(35%)kg $ha^{-1}$, respectively, using Hoagland's nutrient solution.

A suitable supply of mineral elements into shoot via a root system from growth media makes plants favorable growth and yield. The shortage or surplus of minerals directly affects overall physiological reactions to plants and, especially, strongly influences carbohydrate metabolism as a primary response. We have studied mineral uptake and synthesis and translocation of soluble carbohydrates in N, P or K-deficient tomato plants, and examined the interaction between soluble carbohydrates and mineral elements. Four-weeks-old tomato plants were grown in a hydroponic growth container adjusted with suboptimal N ($0.5mmol\;L^{-1}\;Ca(NO_3)2{\cdot}4H_2O$ and $0.5mmol\;L^{-1}\;KNO_3$), P ($0.05mmol\;L^{-1}\;KH_2PO_4$), and K ($0.5mmol\;L^{-1}\;KNO_3$) for 30 days. The deficiency of specific mineral element led to a significant decrease in its concentration and affected the concentration of other elements with increasing treatment period. The appearance of the reduction, however, differed slightly between elements. The ratios of N uptake of each treatment to that in NPK sufficient tomato shoots were 4 (N deficient), 50 (P deficient), and 50% (K deficient). The P uptake ratios were 21 (N deficient), 19 (P deficient), and 28% (K deficient) and K uptake ratios were 11 (N deficient), 46 (P deficient), and 7% (K deficient). The deficiency of mineral elements also influenced on carbohydrate metabolism; soluble sugar and starch was substantially enhanced, especially in N or K deficiency. In conclusion, mineral deficiency leads to an adverse carbohydrate metabolism such as immoderate accumulation and restricted translocation as well as reduced mineral uptake and thus results in the reduced plant growth.
