As global climate change is expected to influence regional water resources, water resource managers need to establish adaptive management to cope with climate change. We examined adaptive management efforts in the US, UK, Canada, Australia, and the Netherlands. Each country is implementing different levels of adaptation efforts based on current water management practices, institutional arrangements, as well as the varying degree of water availability, current climate effects and expected climate change effects. Based on the comparison of these countries, we suggest policy implications for the sustainable water resource management of Korea under climate changes.

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 expansion of irrigated agricultural production can be appropriate for the southeast region in the U.S. as a climate change adaptation strategy. This study investigated the effect of supplemental development of irrigated agriculture on the regional economy by applying the supply side Georgia multiregional input-output (MRIO) model. For the analysis, 100% conversion of non-irrigated cultivable acreage into irrigated acreage for cotton, peanuts, corn, and soybeans in 42 counties of southwest Georgia is assumed. With this assumption, the difference in total net returns of production between the non-irrigation and irrigation method is calculated as input data of the Georgia MRIO model. Based on the information of a 95% confidence interval for each crop's average price, the lower and upper bounds of estimated results are also presented. The total impact of cotton production was $60 million with the range of $35 million to $85 million: The total impact of peanuts, soybeans, corn was $10.2 million (the range of $3.28 million to $23.7 million), $6.6 million (the range of $3.1 million to $10.2 million), $1.2 million (the range of -$6 million to $8.5 million), respectively.

The way to respond to climate change is divided into mitigation and adaptation. So far, the response of climate change has been focused on mitigation. The perception of response of climate change also has been focused on mitigation. However, climate change mitigation and adaptation should be highlighted in a comparable concept as a response to climate change. On the other hand, perception of the public on climate change affects the support or opposition of the general public about climate change-related policies. The purpose of this study is to assess awareness of the general public and stakeholders on the subject of climate change adaptation and to present a basis for a future national climate change adaptation policy. Questionnaire on awareness of climate change adaptation were composed of the climate change and climate change response (mitigation, adaptation) understanding and importance, the seriousness of climate change-related adverse climate event, the need for climate change adaptation measures, the degree of implementation, and the level of government effort for climate change response. Climate change adaptation-related awareness survey was conducted for the general public 1,011 people and stakeholders 101 people by telephone interviews. In this study, the perception survey has a difference in aspect of the contents and methodology. And We were able to present the three characteristics of the general public and stakeholders aware of the subject of climate change adaptation. First, the relative importance of climate change adaptation was relatively low. Second level of awareness about climate change response of the public was significantly lower than the stakeholders. Finally, the need to prepare the implementation of the sectoral level, the first adaptation measures was relatively low.

There is a growing interest in establishing a regional climate change adaptation policy as the climate change impact in the region and local scale increases. This study focused on the analysis of 32 regions on its characteristics of local climate change adaptation plans. First, statistic program R was used for conducting cluster analysis based on the frequency and budgets of adaptation plan. Further, we analyzed damage frequency from newspapers regarding climate change impacts in eight categories which were caused by extreme weather events on 2,565 cases for 24 years. Lastly, the characteristics of climate change adaptation plan was compared with damage frequency patterns for evaluating the adequacy of climate change adaptation plan on each cluster. Four different clusters were created by cluster analysis. Most clusters clearly have their own characteristics on certain sectors. There was a high frequency of damage in 'disaster' and 'health' sectors. Climate change adaptation plan and budget also invested a lot on those sectors. However, when comparing the relative rate among regional governments, there was a difference between types of damage and climate change adaptation plan. We assumed that the difference could come from that each region established their adaptation plans based on not only the frequency of damage, but vulnerability assessment, and expert opinions as well. The result of study could contribute to policy making of climate change adaptation plan.

The ubiquitous computing environment could provide better service to users by adapting to changing contexts. In this paper, we developed a context adaptation system, which enables an ubiquitous program to adapt to different contexts, following its adaptation rules. Using this system, programmers can develop ubiquitous programs suitable for changing contexts, by describing the context adaptation policy. The context adaptation engine of this system fits the ubiquitous program to the current context based on the context adaptation rules. This system was implemented using JCAF, context-aware programing framework based on java. A simulator is also provided to simulate ubiquitous programs by changing contexts.

Social services are divided into care services and other support services for the elderly, children and the disabled. These social services are the subject of great policy interest in that they can create two effects at the same time: increase in labor demand for service providers and increase the possibility of long-term accumulation of human capital for service recipients. Therefore, this study aims to confirm the hypothesis according to whether the use of social services affects family relationships and the effects of social service users' psychological adaptation on marital and parent-child relationships even when other related variables are controlled. The final result of this thesis is a regression analysis to find out the effect of psychological adaptation on the family relationship, spouse relationship, and relationship with children of subjects who have experience using social services. -.661, p=0.001), the higher the psychological adaptation, the higher the spouse satisfaction (β=.465, p=0.001) and relationship satisfaction with children (β=.360, p=0.001). In other words, it was found that the more depressed the psychologically, the more negative the relationship with spouse and children.

Climate change affects human and natural environment. Many countries, including Korea, are trying to develop climate change adaptation strategies to minimize adverse impacts of climate change. To deal with climate change efficiently, decisions have to be made among many options. The objectives of this paper is to analyzes methodologies for prioritizing climate change adaptation measures. Each methodology has strength and weakness and information requirements are differ. We find multi-criteria analysis is one of useful tools considering current level of understanding on climate change adaptation. We suggest climate change risks(timing, likelihood, intensity of climate change impacts), feasibility of policy (equity, main-streaming, democracy), effectiveness (economic effectiveness, co-benefits, propagation effects) of adaptation measures as main evaluation criteria of prioritization.

The purpose of this study was to investigate the effect of group art therapy program on self-esteem and school life adaptation of high school girls. For this purpose, a group art therapy program was performed for 6 students of S girls' high school in S city in Chungcheongnamdo and the effects were analyzed by integrated method. The main results are as follows. First, group art therapy programs were found to positively affect the self-esteem of high school girls. Second, it showed a positive effect on school life adaptation of high school girls. However, there were some cases in which there was a significant change in self-esteem only by quantitative analysis and a change in school life adaptation only by qualitative analysis. Finally, based on this study, the policy measures to improve lowered self-esteem and low adaptation to school life of high school girls were discussed.

This study developed an evaluation system of adaptation countermeasures for climate change in the water resources sector using the Analytic Hierarchy Process (AHP), and the assessment procedures were applied to the Second Chungcheongnam-do Climate Change Adaptation Implementation Plan (Chungnam Implementation Plan). Firstly, the evaluation criteria are composed of two levels according to the hierarchical structure, and AHP gives priority to 4 evaluation criteria of the first level and 16 alternative indicators of the second level. Secondly, after the importance of the evaluation criteria or indicators has been determined, the significance of each measure was evaluated by applying it to the water-sector measures of the Chungnam Implementation Plan, and the effectiveness of the evaluation system was validated. The Chungnam case study shows that the evaluation system will be more effective and efficient when it is applied during development phase rather than after the implementation plan is finalized. It is also expected that the evaluation system will be used to evaluate and prioritize climate change adaptation policies in other regions, and then to compare the means of adaptation to climate change in various regions and to select recommendation policies.
