최근 에너지 정책이 장기화되는 이유는 에너지 정책에 영향을 주는 변수가 증가하고 이러한 변수가 갖는 영향력의 불확실성이 높아짐에 따라, 단기적 단편적 접근을 통해 에너지 이슈에 대한 근본적인 대처가 어려워졌기 때문이다. 에너지 정책을 장기적 관점에서 다루기 위해서는 기존과는 다른 거버넌스적 접근이 필요하며, 이와 같은 맥락에서 전환이론을 에너지 정책에 적용하기 위한 연구가 활발히 진행되고 있다. 본 연구는 네덜란드의 전환관리 모델과 에너지 전환사례를 바탕으로 수정된 전환관리 모델을 제시하고, 이를 기반으로 우리나라 에너지 정책의 시스템 전환적 특성을 평가하는 것을 목적으로 한다. 분석 결과 우리나라의 에너지 정책형성 과정에 전환적 사고가 폭넓게 확산되어 가고 있으나, 정책집행 과정을 중심으로 효과적인 전환관리를 위해 대응해야할 과제도 존재하고 있음을 확인하였다.

The next generation Internet protocol(IPv6: Internet Protocol version 6) has been introduced to overcome the limitations of IPv4 and will be essential element for our industry environment. Transition to IPv6 is not simply replacing a protocol but complex work which affects the whole network. So, the accomplishment of appropriate plans and the systematic transition activities are required. In this paper, we examined the necessity of IPv6 transition and suggested the transition strategy in major parts of transition, such as networks, applications, and address management system.

The Purpose of this paper contribute to design the multistate Markov process for the reliability of a system when the transition-rates of each unit depend on the current state of the system. The system transition-rate matrix has the form of the kronecker sum of transition rate matrices for the units, is analyzed and investigated. As a result, the system which has the state-dependent units is detaily analyzed and introduced by the approach of an algorithm for the system transition-rate matrix based on the kronecker algebra.

Besieged by needs for upgrading the current Internet, social pressures, and regulatory concerns, a network operator may be left with few options to Improve his services. Yet he can still consider a transition prioritizing network services. In this paper, we describe a transition from a non-priority system to a prioritized one, using non-preemptive M/G/1 model. After reviewing the constraints and theoretical results from past research, we describe steps making the transition Pareto-improving, which boils down to a multi-goal search for a Pareto-improving state. We use a genetic algorithm that captures actual transition costs along with incentive-compatible and Pareto-Improving constraints. Simulation results demonstrate that the initial post-transition solutions are typically Pareto-improving. for non Pareto-improving solutions, the heuristic quickly generates Pareto-improving and incentive-compatible solutions.

In this research, we explore how to manage the transition of technology generations considering incremental innovation of the existing technology generation. Firms can slow down decaying of the existing technology by continuous incremental improvements rather than introducing a new generation technology at the first time if the former strategy is better. We characterize optimal technology transition problem by setting up an optimal control model. The model which is originally designed and solved by Thompson(1968) as a ‘Machine maintenance problem’ has been cited to build the main body of our model. With this analytical model, we derive optimal ‘incremental innovation’ strategy which is considering transition to the next technology. Our analysis indicates that there exists an unique ‘stopping incremental innovation timing’. Before the point of time, the decision maker should make his effort at a maximum level to enhance the current technology. However from the stopping timing to the final time horizon where the new technology is introduced, it is found that not to invest to the current technology any more is optimal.

사회-기술 시스템의 근본적 변화를 다루는 전환연구가, 지속가능한 발전에 대한 논의 확대를 배경으로 정책적 활용의 폭을 넓혀가고 있다. 본 논문의 목적은 대표적인 전환이론인 다층적 관점, 전환관리, 전략적 니치관리 및 기술혁신시스템 이론의 특징과 정책적 함의를 고찰하고, 이를 전환정책 설계와 운영과정에 활용하기 위한 통합적 분석틀을 제시하는 것이다. 각 전환이론은 서로 다른 연구적 입장을 견지하고 있으나, 사회-기술 시스템의 근본적 변화를 동태적으로 분석하고 있다는 점에서 상호보완적이다. 따라서 전환현상이 복잡해지고 전환에 영향을 미치는 변수가 확대될수록, 각 이론의 연계 및 통합적 활용에 대한 필요성이 높아지고 있다. 최근 국내에서도 전환이론을 혁신정책 및 과학기술정책에 접목하기 위한 연구가 진행되고 있으며, 전환적 사고가 반영된 정책도 등장하고 있다. 기후변화, 에너지 자원의 활용 등 우리 사회와 정부가 대응해야 할 지속가능성 이슈가 증가할수록, 효과적인 전환정책의 설계와 운영에 대한 필요성은 증가하게 된다. 본 논문은 개별 전환이론에 대한 비판적 고찰을 토대로 통합적 전환정책 분석틀을 도출하고, 우리나라의 스마트그리드 정책사례에 예시적으로 적용하여 분석한 결과를 제시한다.

For a continuous-time absorvation Markov chain, we apply and simplify the general method of finding the transition rates given the transition probabilities obtained from discrete observation of the continuous system. An example is given.

The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient's developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients' knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients' adherence to therapy, maintain the appropriate health status, improve patients' self-management, and promote self-reliance among patients.

Although the demand for IT outsourcing (ITO) has increased recently because of the recent recession, concerns about business discontinuity in the transition phase cause companies to hesitate to adopt ITO. Therefore, a guideline to improve the prospects is needed. However, studies on the success factors of the transition phase in ITO are lacking. In this study, we develop an expert hierarchical value map (HVM) of the success of the transition phase in ITO by using cognition scientific methodologies. We empirically verify how success factors affect the success of the transition phase. Specifically, we derive an HVM of main stakeholders by using in-depth interviews and approaches, such as repertory grid technique (RGT) and laddering, based on means-end chain theory. We validate the success factors empirically through a bipolar analysis of RGT. Finally, we determine the most important cluster of success factors through cluster analysis.

The purpose of this study was to understand the lived experiences of grandmothers and family in transition. Grandmothers in transition means grandmothers who had married children at least one even if there are no grandchildren yet. The data for this study came from 20 grandmothers in transition of 5 focus group(each 4 persons) interview. 9 of them was pre-grandmother without grandchildren yet, 11 was grandmother who had grandchildren. The result of this study revealed that the meaning of grandmotherhood. Dynamics of family in transition around supporting child care represent change of family relations. It didn't means 'empty-nest' model of foreign theory. The Absolute quantity of intergeneral exchange and conflict extended as three generational families.
