본 논문은 세션 관리 기능을 포함한 차량 네트워크 환경을 위한 오류 처리에 대해서 기술한다. 이 시스템은 FDA(Fault Detection Agent)와 FRA(Fault Recovery Agent)로 구성되어 있다. FDA는 세션 관리 기능을 포함한 차량 네트워크 환경에서 멀티미디어 시스템을 위하여 훅 킹 기법으로 오류를 감지하는 에이전트이다. FRA는 차량 네트워크 환경에서 세션 관리 기능을 포함한 멀티미디어 시스템을 위한 소프트웨어 오류를 복구하기에 적합한 에이전트이다. 본 논문에서는 FRA에 범위를 한정한다. 여러 개의 지역 세션이 동시에 개설 되었을 경우에 각 지역 세션 관리자는 자신의 세션에 속한 참여자들에 대한 정보를 전체 세션 관리자에게 제공해서 네트워크에서 진행 중인 세션에 대한 최신의 정보를 유지한다.

This study aimed to find the association between geographic proximity and program participation at a Healthy Family Support Center (HFSC). Drawing demographic and geographic information from the participant list at a local HFSC in Seoul for the period 2009 to 2011, this study calculated the geographic distance from the individual residence to the center for 2,343 participants. We found that single time participants had a longer distance from their residence to the center than multiple time participants. When we compared the proximity by program areas, we found that the geographic distance to the center was shorter among education program participants than among non participants. However, there was no difference in the other areas of programs. In terms of the target group, the distance was shorter among adult program participants. Finally, the average distance among participants in multiple session programs was shorter. The results of this study indicated that the relationship between geographic proximity and program participation depended on program areas, target groups, and the number of sessions.

Background: The aim of this study is to assess the feasibility of acupuncture treatment for the management of subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures. Methods: A total of 30 participants who have undergone thoracotomy after traumatic multiple rib fractures will be recruited. Participants will be invited and equally randomised into acupuncture plus usual care and usual care alone groups. A computer-generated random number sequence will be used and concealed using opaque, sealed, sequentially numbered envelopes. Twelve sessions of manual and electrical acupuncture performed by Korean medicine doctors will be provided over a span of 3 months to participants allocated to the acupuncture group. Participants in the usual care group will continue pain medication, exercise and physical therapy as required. Study feasibility will be measured based on the proportion of patients who complete the measurement of pain at 12 or 24 weeks after baseline. The clinical outcomes will include; the average pain intensity over the recent week at rest, movement and cough, quality of life, patient's global assessment of recovery, respiratory function measured by the pulmonary function test and use of pain medication at 4, 8, 12 and 24 weeks after enrolment. Adverse events will be recorded for all participants. Written informed consent will be obtained from all participants. The local ethics committee has approved the study. This pilot trial will inform further studies investigating the potential role of acupuncture for subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures.

This study aimed to verify the positive effects of forest activities for children from economically underprivileged households in local children's centers and the effect of such activities on the protective factors of their development. One hundred and eighty five children participated in the Forest Activities Program, which conducted over a total 8 sessions. Pre-post tests of the subjective well-being scale, DAS, multiple life satisfaction scale, ego-resilience scale were conducted and the children then made picture stories during the program itself. The results of the analysis of differences between pre-post tests were as follows: first, the negative emotions of participating children decreased significantly. Second, the school-satisfaction and self-satisfaction levels of the participating children increased. Third the participating children's positive perceptions of self and interpersonal relationships also increased through the forest activities. Finally, there were differences of the change types of picture stories that children created while they were participating in the program; and these divergences were related to the effectiveness of the program. These forest activities had positive effects upon the economically disadvantaged children who participated in this study. However, in order to increase the effects of such forest activities qualitatively, greater support for the active involvement of children is required.
