Full-mesh IPSec tunnels pass through a black ("unsecure") network (B-NET) to any red ("secure") networks (RNETs). These are needed in military environments, because they enable dynamically changing R-NETs to be reached from a BNET. A dynamically reconfiguring security policy database (SPD) is very difficult to manage, since the R-NETs are mobile. This paper proposes advertisement process technologies in association with the tunnel gateway's protocol that sends 'hello' and 'prefix advertisement (ADV)' packets periodically to a multicast IP address to solve mobility and security issues. We focus on the tunnel gateway's security policy (SP) adaptation protocol that enables R-NETs to adapt to mobile environments and allows them to renew services rapidly soon after their redeployment. The prefix ADV process enables tunnel gateways to gather information associated with the dynamic changes of prefixes and the tunnel gateway's status (that is, 'down'/restart). Finally, we observe two different types of performance results. First, we explore the effects of different levels of R-NET movements on SP adaptation latency. Next, we derive the other SP adaptation latency. This can suffer from dynamic deployments of tunnel gateways, during which the protocol data traffic associated with the prefix ADV protocol data unit is expected to be severe, especially when a certain tunnel gateway restarts.

The purpose of this study is to understand the experience how children are receptive to their parents' imprisonment, adaptation from their painful experience and crisis. In order to achieve the purpose of the study, six youth participants were selected. We carried out in-depth individual interviews and the collected data from the interviews and the case study were analyzed. The commons subjects are like 'Sudden separation and shock', 'Glad to be unhappy', 'Wretched my life', 'The way of the far-away meeting', 'The one who gave me hope', 'Live my life'and so on. Based on the result of this study, policy and practical guideline were discussed and suggested to help children of the incarcerated in addition to the limitations of the study and the recommendations for further study.

Purpose: This study aimed to develop an evidence-based nursing practice guideline for preventing postoperative pulmonary complications (PPCs). Methods: The guideline adaptation process was conducted through the 24 steps based on the guideline adaptation manual of Korean Hospital Nurses Association. Results: The newly developed guideline to prevent PPCs consisted of four domains and 30 recommendations. The number of recommendations in each domain was 7 for assessment of PPCs, 17 for nursing interventions to prevent PPCs after general anesthesia, 4 for education (intended for patients and medical staff), and 2 for monitoring and recording. Conclusion: The developed guidelines will contribute in standardization of nursing practice and PPCs prevention and management. We recommend the dissemination and utilization of these guidelines nationwide to improve the quality of postoperative pulmonary complication prevention.

This paper describer a design expert system which determines the design values of shadow mask using Case-Based Reasoning. In Case-Based Reasoning, it is important to both retrieve similar cases and adapt the cases to meet the design specifications exactly. Especially, the difficulty in automating the adaptation process will prevent the designers from using the design expert systems efficiently and easily. This paper explains knowledge-based design support systems for shadow mask through neural network-based case adaptation. Specifically, we developed 1) representing design knowledge and 2) adaptive case-based reasoning method using RBFN (Radial Basis Function Network).

The purpose of the thesis is to answer the question on how the visual image content, being the original content, should be adapted to and represented as a spatial content. The thesis focuses on adaptation as the key in the conversion process of visual image content to a themed space. There are many published studies dealing with storytelling, adaptation from books to movies and TV shows, or from movies to games and vice versa. On the contrary, when it comes to adaptation from visual image content to spatial content, noticeably few studies were done on the method, and fewer studies view adaptation as the prior step of storytelling. This study first defines adaptation, and then applies the methods of Gianetty and Dudley which is further incorporated into the conversion of visual image content into a themed space. It then turns the attention to the characteristics of themed spaces. A case study highlights that a themed space is a spatial representation of the story, image and action in the visual image content, and analyze the type of adaptation made. The study results draws two conclusions; adaptation must be carried out prior to the storytelling of the spatial content; and opposed to a third-person view of the visual image content, the main factor in a themed space is first-hand experience. Thus, the thesis suggests that conversion from visual image content to themed spaces are not merely imitative but is a full range of recreation of a new content. It is expected that more detailed analyses on the particulars will lead to feasible outcome on implementing various methods of adaptation and bring about effective conversions between the visual image contents and themed spaces.

This study was a qualitative investigation of the process of adaptation of nutrition education programs by marriage immigrant women who completed education programs for training of food citizen leaders. Focus group interviews of seven marriage immigrant women from Vietnam, China, Mongolia and Russia were conducted and analyzed based on the Normalization Process Theory (NPT). Participants were aware of the purpose of the education program (coherence) and their confidence in organizing and reconstructing the knowledge of nutrition was increased after education (reflexive monitoring). However, they had difficulties attending long-term education programs (cognitive participation) and overcoming language barriers (collective action). Although the program was beneficial for the participants in that they could apply acquired nutrition knowledge to their everyday life as food citizen leaders, the continuous monitoring and feed-back system (management), customized application, and consideration of personal and social factors need to be developed and facilitated. In addition, various programs targeting marriage immigrant women may increase economic independence of these women. The NPT proved beneficial in conceptualizing the barriers and facilitators to implementing nutrition education. The successful implementation of nutrition intervention needs special support to overcome barriers to cognitive participation and collective action.

The purpose of this study is to examine how the long-term care effects the elderly that adapt themselves to the caring facility, what their experiences are and what kinds of behavioral characteristics they present. We have analyzed the research conducted on 15 elderly individuals who are living in an elderly long-term care facility, by using the grounded theory approach of Strauss and Corbin (1998). As a result, 170 concepts, 42 sub-categories, and 15 categories were set by the open coding process. During the adaptation process in a long-term care facility, the primary experience or feeling by the elderly is that they had been 'deserted'. However, when consolidating the casual conditions, contextual conditions, intervening conditions, the action/interaction strategy, and consequence, the primary experience was that the elderly came to an 'acceptance'. Such acceptance was then sub-categorized into a destiny-resignation type, reality-acceptance type, and voluntary-selection type. Based on the results of this study, we recommend practical alternatives which will improve surrounding circumstances including caring facilities, its employees, relationships with other elderly individuals, and family support.

This paper proposes a new echo canceller that can be used in a full-duplex digital subscriber loop modem. The proposed echo canceller uses a NLMS-based parallel adaptation NLMS (PA-NLMS) algorithm. The PA-NLMS algorithm that an estimate of the nonstationarity to additive noise ratio (NNR) gained from two distinct NLMS processes is used to select the value of NLMS convergence-controlling parameter has been developed. Numerical results based on computer simulation show that the proposed algorithm has a convergence rate approaching that of the fastest possible NLMS process while improving on its MAC performance considerably.

This paper describes a novel approach to adaptive courseware generation. This approach adopts its structure from existing intelligent tutoring systems and introduces a new component called pedagogical scenario model to support pedagogical flexibility in the adaptation process of courseware generation system. The adaptation is carried out using Dynamic Constraint Satisfaction Problem framework, which is a variant of classical Constraint Satisfaction Problem, to deliver courseware tailored to individual learner. Such a framework provides a high level of expressiveness to deal with the particular characteristics of courseware generation problem. Further, it automatically designs a sound courseware satisfying the design constraints imposed by the domain, the pedagogical scenario and learner models.
