Finite element method(FEM) was used to obtain an approximate solution, since the mathematical formulations for the problem are complex and cannot be solved analytically. In this study, the fruit as well as the aluminum support on vibrator are discretized into small elements, and the approximate functions are used to describe the displacements in each element in terms of nodal values, and because of the complexity of the problem of viscoelastic materials such as the fruit and vegetables, it was necessary to validate the modeling approach before pear simulations were performed, and the finite element modeling approach was first validated by comparing the results obtained from simulation and experiment for the pear in the frequency range 3 to 150 Hz and acceleration level of 0.25 G-rms. Based on the relatively good agreement between simulated and measured frequencies for the pear, finite element models of tomato and oriental melon were created to study the vibration characteristics of the fruit and vegetables. The resonance frequencies of the pear, tomato and oriental melon using FEM were 62.50, 39.45 and 62.73 Hz and the peak accelerations of them using FEM were 2.21, 1.38 and 1.98 G-rms.

CALS/EC의 도입ㆍ활용은 생산 및 유통비용의 감축과 업무처리시간 단축 및 조직간 정보교환의 원활화를 통해 산업 및 국가경쟁력 향상에 기여하는 것으로 알려져 있다. 이제 제조업이나 서비스업을 막론하고 세계화의 추세에 맞춰 국제적으로 경쟁력을 갖춘 기업으로 성장하기 위해서는 CALS/EC의 도입이 필수적으로 요구되고 있다. 우리나라와 같은 CALS/EC 후발국의 입장에서 볼 때, CALS/EC 도입 환경이 제대로 성숙되어 있지 못한 채 구체적인 도입 유형 및 방법론 등에 대한 연구가 취약하여 도입 관련 의사결정에 많은 어려움을 겪고 있는 실정이다. 결국 CALS/EC 도입 의사결정에 수반된 도입 목적의 파악 및 효과 측정방안, 대상요소기술의 선택, 적용 대상분야의 산정 등에 관한 구체적인 대안제시가 실무적으로 요구되고 있다. 본 연구는 위와 같은 문제점을 인식하고, CALS/EC 도입과 관련된 의사결정을 위한 기반연구를 수행함에 그 목적이 있다. 이를 위해 CALS/EC가 그 유형별로 고유한 특성이 존재한다는 전제하에 우선 CALS/EC의 유형별 분류체계 정립을 시도하였으며 각 유형의 차별성을 부각하는 유형별 특성 모형을 개발 제시하였다. 다만 본 연구의 결과물을 근거로 수립될 구체적인 유형별 도입방법 및 절차는 후속연구에서도 다루기로 한다.

Currently digital contents such as games, animation and video art are produced and distributed actively. And moreover by the development of related industries, a variety genre of media is in the process of planning and production. However general-purpose tools such as MAYA and Soft Image do not provide the artists in terms of a variety of unique functions. Thus in this study, we analyzed and developed interface technologies that can help effectively in terms of animation scenario writing, storyboard simulation, rendering and pre-production of story board, interface technology for preview. By our designed simulate planning, people who not professional in the field of animation, can produce and preview animation easily.

This paper presents an analysis of construction project management from supply chain management perspective to gain insight from all constituents and to identify areas of improvement. In order to suggest opportunities for improvement, interviews with the members of a typical urban office building project in US were held. Based on that, a qualitative analysis of construction projects is presented. Focusing on electrical and mechanical sub-systems, this study illustrates the roles of subcontractors, suppliers, distributors, and manufacturing representatives as well as the complexity that a general contractor fares in managing its supply chain. The author$^{\circ}\phi$s recommendations are focused on process restructuring and automation, which include some quantifiable performance measures, incentives, and their alignment with each other

The diffusion of the internet, the advancement of ICT technology, and digital diffusion have facilitated the streamlining and acceleration of scholarly communication and speeding up research, and the paradigm of scholarly information dissemination is changing. This study introduces the ORCID, a unique author identifier, and examines the ORCID organization's activities, the advantages given to researchers and research institutes, and the membership status. In addition, this paper examines adoptions and utilizations of ORCID in major countries including USA, UK, Italy, and China. Based on this, this paper suggests the necessary considerations for utilizing ORCID in terms of governance, system elements, policy and institutional aspects in an effort to identify authors at national level.
