적응순항제어시스템은 선행차량과의 거리와 속도를 자동적으로 안전하게 유지하여 운전의 안전성과 편의성을 향상시키는 시스템이다. 본 연구에서는 적응순항제어시스템의 안전성을 향상시키기 위한 연구를 수행하였다. 적응순항제어시스템의 작동 상태 및 주변 차량 정보를 운전자에게 제공해 주기 위한 시각 및 음성정보 전달장치를 설계 및 제작하였다. 시각정보 전달장치를 통해 선행차량과의 차간거리, 속도, 가감속 상태 등을 운전자에게 전달하였고, 음성정보 전달장치를 이용하여 선행차량과의 근접거리 경보 등의 메시지를 전달하도록 하였다. 이러한 조건에서 운전자가 적응순항제어시스템을 사용하여 운전하는 경우, 시각 및 음성정보 전달장치의 유무에 따른 차량 조작과 차량 운전 성향 및 특성의 변화를 살펴봄으로써 정보전달장치를 통한 안전성 향상에 관한 영향을 연구하였다. 연구 결과, 운전자에게 정보 전달장치를 통해 정보가 제공되었을 경우, 운전자는 차량의 운전 및 적응순항제어시스템 사용에 있어 편안함을 느낄 수 있었고, 선행차량과의 차간거리를 보다 넓게 설정하여 주행 안전성을 향상시키는 것을 확인할 수 있었다. 또한 정보전달장치를 통한 정보 수집이 차량 운행에 저해 요인으로 작용하지 않음을 확인할 수 있었다. 이러한 결과는 정보전달장치를 통한 정보전달은 운전자에게 적응순항제어시스템에 대한 편의성 및 효율성, 안전성을 더욱 향상 시킬 수 있음을 보인다.

소프트웨어가 수행되는 환경은 점점 복잡해지고, 예측이 어려워지고 있지만, 소프트웨어의 자율성과 견고성을 달성하는 것은 여전히 어려운 문제 중에 하나이다. 적응형 소프트웨어는 소프트웨어의 복잡성을 해결하고 자율성과 견고성을 달성하는데 기여할 새로운 소프트웨어 개발 패러다임으로 떠오르고 있다. 적응형 소프트웨어는 환경과 자신의 상태를 인지하고 현재의 성능을 향상시킬 방법을 스스로 판단하여 소프트에어의 구조 및 행위를 변경할 수 있는 소프트웨어이다. 본 논문에서는 적응형 소프트웨어의 개발 초기단계에서 요구사항 분석 단계에서 추출된 목표와 시나리오를 이용하여 어떻게 적응형 소프트웨어의 각 기능을 정의하는 방안을 제시한다.

본 논문에서는 열탄점소성 손상과 접촉 문제의 효율적인 해석을 위하여 적응성 영역/경계 분할법을 제안하였다. 적응성 영역/경계 분할법은 시간 증분 또는 반복 기법 단계에서 열탄점소성 손상과 같은 재료 비선형성을 감안하여 부영역을 재설정하며, 접촉에 따른 경계 비선형성은 경계면을 통하여 부영역으로부터 독립적으로 분할한다. 분할된 각각의 부영역과 경계면을 기준으로 유한요소 정식화를 수행하며, 공유면 및 접촉 공유면의 연속 구속 조건을 처리하기 위하여 벌칙 함수 기법을 적용하였다. 결과적으로 재료 및 경계 비선형성은 일부 부영역과 접촉 경계면에서 계산되는 유한요소 행렬에 국한된다. 수치 실험을 통하여 적응성 해석 알고리듬의 기본적인 특성과 효율성 향상에 대하여 분석하였다.

This study examined the mediating effects of aggression in the associations between marital conflict and school adjustment for adolescents. Participants were 482 middle school students of Seoul. Statistical methods of correlational analysis and regression analysis were used with SPSS WIN 25.0. The results of this study showed that marital conflict had positive influences on aggression of adolescents. School adjustment was negatively affected by aggression of adolescents. Marital conflict was found to have negative direct effects on school adjustment for adolescents. The results from regression analysis indicated that aggression mediated the relationship between marital conflict and school adjustment for adolescents.

This study was conducted to investigate the relationship between contingencies of self-worth(superiority and others' approval), college adjustment and expectancy for future success and the mediating role of cognitive flexibility in these relationships. For this study, data from 460 college students were analyzed. The results were as follows. Contingencies of self-worth(superiority) were positively associated with college adjustment and expectancy for future success, while contingencies of self-worth(others' approval) were negatively associated with college adjustment and expectancy for future success. Second, the results of structural equation modeling indicated that cognitive flexibility fully mediated the relationship of contingencies of self-worth (superiority and others' approval) with college adjustment and expectancy for future success. Third, even the contingencies of self-worth(other's approval) were negatively associated with cognitive flexibility, and if the latter was high, it influenced college adjustment and expectancy for future success. Finally, the meanings and limitations of this research and implicationsfor counseling strategies and interventions were discussed in detail.

This study aims at deriving the implications for adaptation policy and research target regarding climate change risk assessment in ecosystem sector in Korea. The common ground of exemplary cases of "world leaders" in terms of adaptation policies and researches was that they emphasize nationwide study on climate change on biodiversity and ecosystem in target of establishing scientific evidence-bases and reducing uncertainty for their national adaptation policies and plans. In light of this trend, Korean government should settle down more successful adaptation structure by leading adaptation system in further national policy-settings to observe UNFCCC and CBD integratedly and effectively, considering the economic value of adaptation in policy, and strengthening scientific research programs and technology developments. Moreover, risks assessment based on diagnoses and analysis on the risk factors (hazard, exposure, and vulnerability) for climate change in nationwide habitats and species and consolidations with subsequent adaptation strategies could make adaptations in ecosystem sector more effective and successful.

The purposes of this study are to find out the differences of parent-adolescent communication patterns, family cohesion and adaptability according to socio-demographic variables, to estimate the differences of family cohesion and adaptability according to parent-adolescent communication variables and to offer the basic data that are needed to improve desirable parent-adolescent communication, family cohesion and adaptability. Results of these analysis can be summarized as follows. 1. Open communication with father was showed significant difference according to adolescent's birth order. Close communication with father was showed significant difference according to adolescent's sex, adolescent's birth order and family type. Open communication with mother was showed significant difference according to adolescent's sex. Close communication with mother was showed significant difference according to adolescent's sex and birth order. 2. Family cohesion was significantly different adolescent's sex and income level. And family adaptability was significantly different adolescent's set adolescent's birth order and income level. 3. Family cohesion was influenced by open communication with father, open communication with mother, income level and adolescent's sex.

정운동학을 이용하여 인간의 걷는동작을 표현함에 있어 제어의 단순화와 환경에 대한 적응성은 매우 중요하다. 무게중심을 이용한 동작제어방법은 제어의 단순화에 많은 기여를 하였으나, 환경에 대한 적응성은 크게 만족시키지 못하였다. 본 논문에서는 걷는 동작의 내부동작들을 동기화하여 환경에 대해 적응성을 높이는 방법에 대해 살펴본다.

A self-adaptation with context-awareness is needed within network to meet costumed services according a user's changing constraints. But the existing network has many difficulty in adding new functions because of slow standardization of network and slow deployment of new services. To solve this problem, an active network can support the suitable environment to add new function such as self- adaptation. Therefore, this Paper suggests Self Adaptation Service(SAS) using agent-based active network and the constraint-based Service Creation Environment(SCE) to support self-adaptation with context-awareness. SAS provides benefits to support the context-aware service and the fast deployment of new services.
