IT 투자 평가를 위한 지표 도출 및 투자관리체계에 관한 연구
장강일,강성민,김진수 한국경영과학회 2002 한국경영과학회 학술대회논문집 Vol.- No.1(2)
This study discusses the prior researches on concepts regarding the analysis of IT investment effect in an organization as proposed from academic and professional perspectives. In addition, we looked at the possible issues that can arise from implementation stage based on the example of development of IT investment management process at Company A. This study makes contribution in examining the potential issues and their relevant solutions when implementing the management process/system of IT investment based on the case of Company A. At Company A, there is much knowledge that is being adopted directly from suggested principles of the academic and professional fields as employee needs and requirements are met in advance. But, there is customized knowledge as well in order to best describe the specific situation. We partly try to distinguish the concepts and realities by understanding the core issues involving the IT investment management process/system and make practical suggestions for the companies that plan to implement the efficient IT investment management process/system in the future.
그라운드 빔 조인트 기반 위상최적화법을 이용한 프레임 구조물의 조립 위치 및 강도 설정

Most frame structures cannot be manufactured in a single-piece form. Ideally, when a structure is built up by assembling multi pieces, assembly at the joints should be rigidly performed enough to have almost full stiffness, which is difficult for practical reasons such as manufacturing cost and time. In this research, we aim to develop a manufacturability-oriented compliance-minimizing topology optimization using a ground beam model incorporating additional zero-length elastic joint elements. In the present formulation, design variables control the stiffness of zerolength elastic joints, not the stiffness of beams. Because joint stiffness values at the converged state can be utilized to select candidate assembly locations and their strengths, the technique is extremely useful to design multi-piece frame structures. An optimal layout is also extracted based on the stiffness values.
日本型イノベ一ション戰略の探究-家庭用ロボット掃除機における事例硏究-
長江庸泰 한국일본근대학회 2013 일본근대학연구 Vol.0 No.41
日本大學人口硏究所[NihonUniversityPopulationResearchInstitute(NUPRI)]の分析によれば、「日本の家族介護力(高齡人口に對する40~59歲の女性人口)は2005年以降、世界192ヵ國中最低水準となり、この傾向は2022年以降50年間續く」ことを指摘している。本論は、サ一ビス支援技術を、高齡者·病人·幼兒などの「身體的弱者向けの支援技術」として再考し、その上で、産學官連携により「生活機能補完技術(すなわちサ一ビスロボット技術)」という新たな産業分野に發展させることにより、國民全員に基礎的な安心感を與えるという「イノベ一ションの觀点」から、①「家庭用ロボット掃除機の事例硏究」と②「コモディティ化の□」の2点に課題解決を絞り迂み、檢證を行うものである。 An analysis undertaken by NUPRI (Nihon University Population Research Institute) indicates that the number of Japanese households able to provide care for the elderly, that is, households containing a woman aged 40 to 59 and an elderly person, have been, since 2005, among the lowest in the world (i.e., 192 states), and this trend is expected to continue for fifty years from 2022 onwards. By reconsidering service support technology for the physically weak, that is, the elderly and the ill, it is possible, through cooperation among industry, academia, and government, to develop a new field of robot technology, a “life function support robot technology (i.e., service robot technology)”, that will provide all citizens with a basic level of security. The two main points that will be examined are as follows. 1. A Case Study of Vacuum Cleaning Robots in the Home. 2. In Search of a “Commodity Trap”.
