Local Agenda 21 organizations have been founded at the most divisions of local government in Chungcheongbuk-Do, but there has been no methods to monitor the total Sustainable Development trends. For the alternative solution of that problem in the Province, this study purposed (1) to develop Indicators fit to this Province (2) to examine the availability of the developed indicators adopting to each division section. Indicators were developed and examined by fields and Quantity / Quality considerations. As a 1st step, committee-composed with field professionals each-selected and developed Quantitative Sustainable Development Indicators(SDIs) optimized to Chungbuk-Province through critical discussions proposing Qualitative Indicators as a suggestion. In 2nd step, developed Indicators were applied and tested upon each divisions. Statistic data were used to calculate indices. 3rd step is adoption stage of Qualitative Indicators which were tested with questionnaire survey analysis. As a results, SDIs for Chungcheongbuk-Do -38 Quantitative SDIs within 4 provisions of 11 items with 8 Qualitative indicators categorization be put off- is developed. With the application test, 5 Quantitative Indicators- were found to be not adaptable because of lack or none of statistic data. Among the 8 Qualitative Indicators, 3 pairs found to be similar results in each pair which needed to be integrated into one. With them, bio-species related and health related Indicators were proposed to be newly added. Nation wide Sustainability comparison between divisions and Ecological Indicator selection are another themes to be considered.

Artificial Intelligence(AI) 기술이 발전함에 따라 데이터 센터 분야 등에서 고사양 반도체에 대한 수요가 증가하고 있다. 이러한 추세에 맞춰 반도체 성능을 향상하기 위해 회로의 미세화 및 I/O의 고밀도화가 요구되고 있으며 이를 충족할 수 있는 기술로 차세대 packaging인 2.5dimension(D) packaging이 주목받고 있다. 2.5D packaging에 활용되는 요소 기술로는 microbump, interposer 및bridge die가 있다. 이러한 기술을 적용하면 기존 방식 대비 더 많은 수의 I/O 구현이 가능하여 동시에 다량의 정보를 송수신할 수 있으며, 전기 신호를 전달하는 배선 길이를 단축하여 전력 소모량을 감소시킬 수 있다. 본 논문에서는 molding 공정 및 R DL공정을 융합하여 제작한 Molded Bridge die on Substrate(MBoS) 공정 기술을 제안한다. 제안된 MBoS 기술은 적용이 쉽고 활용 분야가 넓어 차세대 패키징 기술의 대중화에 기여할 것으로 예상된다.

최근 각종 멀티미디어 서비스의 제공은 전송데이터의 급격한 증가를 가져왔으며, 이러한 서비스의 원활한 제공을 위해서는 초고속 통신망의 구축이 불가피하게 되었다. 초고속 통신망의 구축은 막대한 비용을 요구하기 때문에 망 구축비용의 감소를 위해서는 기존에 설치된 관로를 고려해야한다. 또한 초고속 통신망은 하나의 선로에 많은 양의 데이터가 전송되므로 한 선로에 문제가 있는 경우 막대한 손실이 발생하는 특징을 지닌다. 이 때문에 전체 네트워크를 일정수준이상의 생존도를 가질 수 있게 설계하여야한다. 이러한 문제의 해결을 위해서 기존의 논문에서는 비용을 줄이기 위해 고려된 기존 관로를 다음 단계에서 배제하여 한 관로를 여러 경로에서 사용함으로써 얻을 수 있는 비용 절감효과를 상실하였다. 그러나 본 논문에서는 생존도를 유지하는 범위 내에서 기존에 설치된 관로를 최대한 고려하여 비용 절감을 극대화한 네트워크를 효과적으로 설계하는 방법을 제안한다. 제안한 방법을 사용하여 실험한 결과에 따르면 기존의 방법에 비해 약 7%의 비용절감 효과를 얻을수 있었다.

Purpose: Existing precedent studies include success factors of individual management innovation activities constantly. However, those studies have limitations about the common key success factors of individual management innovation activities. Methods: For this study, we investigate the key success factors using literature research of the most typical management innovation activities adopted and implemented by many companies in Korea, such as 6sigma, TQM, Lean 6sigma, ERP, TPM, BPR, Project Management, System Engineering. Factors emerging repeatedly was combined into common factors and inherent factors that are necessary for the success of individual management innovation activities are designated to essential factors. Results: 'Essential factors for Six Sigma' consist of 5 items. Black belt operating system, personnel management system linkage, the correct management of the data, perform improvement projects associated with financial performance financial result, linked to financial performance improvement project, project progress management. 'Essential factors of TQM' are arranged 4 items. Quality team's independence and role, goal-setting, Quality Information System, corporate's philosophy of quality first. 'Essential factors of Lean Six Sigma' are the selection of value stream which is based on the customer needs and the value creation and identify the project based on the selected value in the company. 'Essential factors of ERP' are investigated 6 items. Ongoing system maintenance and upgrades, the measurement and support of user satisfaction, the operating systems and the policies for the maintenance, IT infrastructure, change adaption condition monitoring, focusing on improving business performance. 'Essential factors for TPM' are arranged 4 items. Motivated and energetic Bottom-Up, CEO's recognition of the importance facility management, long-term perspective of necessity and ongoing patience. 'Essential factors for BPR' are the pursuit of change process and the staff's sense of crisis management. 'Essential factors for Project Management' are the strategy that reduce the risk management skills through risk management and the understanding and organized management for the project participant's needs. 'Essential factors for System Engineering' consist of 2 items. The first is the design for the best balanced system with pre-analysis about the compromise the cost, schedule and the performance. The second is the analysis of large problem into small problems which can solved. We have found the solution considering components of the interface through the systematic perspective. Conclusion: Common factors and essential factors presented in this study will properly help to introduce the individual management innovation activities for the each business sector and implement management innovation. After this study, new literature research that reflect new studies should accomplish steadily.
