This study explores supportive and conflictual network structures of elderly single and couple households and analyzes the effects of supportive and conflictual networks on suicidal thoughts by gender and family type. The analysis considered a sample of 522 individuals over the age of 60 who did not live with their adult children. The statistical methods used to analyze data were descriptive statistics, a t-test, a chi-square test and a regression analysis using SPSS WIN 20.0. The results are as follows. First, men and elderly single households had support networks that were smaller than those of women and elderly couple households. The conflictual network of elderly couples households was larger than that of elderly single households. In addition, the larger the network, the more the conflictual was. Second, elderly single households thought about suicide more often than elderly couple households. Third, economic status, the number of adult children, the size of conflictual network and subjective health had considerable influence on suicidal thoughts of elderly single and couple households. The size of the conflictual network had a greater effect on suicidal thoughts of elderly individuals than that of the supportive network. These results have important policy implications for elderly single and couple households.

Longterm memory is encoded in the neuronal connectivities of the brain. The most successful models of human memory in their operations are models of distributed and self-organized associative memory, which are founded in the principle of simulaneous convergence in network formation. Memory is not perceived as the qualities inherent in physical objects or events, but as a set of relations previously established in a neural net by simultaneousy occuring experiences. When it is easy to find correlations with existing neural networks through analysis of network structures, memory is automatically encoded in cerebral cortex. However, in the emergence of informations which are complicated to classify and correlated with existing networks, and conflictual with other networks, those informations are sent to the subcortex including hippocampus. Memory is stored in the form of templates distributed across several different cortical regions. The hippocampus provides detailed maps for the conjoint binding and calling up of widely distributed informations. Knowledge about the distribution of correlated networks can transform the existing networks into new one. Then, hippocampus consolidats new formed network. Amygdala may enable the emotions to influence the information processing and memory as well as providing the visceral informations to them. Cortico-striatal-pallido-thalamo-cortical loop also play an important role in memory function with analysis of language and concept. In case of difficulty in processing in spite of parallel process of informations, frontal lobe organizes theses complicated informations of network analysis through temporal processing. With understanding of brain mechanism of memory and information processing, the brain mechanism of mental phenomena including psychopathology can be better explained in terms of neurobiology and meuropsychology.

이 논문은 지속가능한 발전(또는 개발)에서 지속가능성 개념을 생태윤리적인 측면에서 지속가능성이 가지는 의미를 분석해보고, 생태윤리에서 지속가능성의 특징을 제시하고 있다. 생태적 지속가능성에 대한 논의에서 우선 지속성과 변화를 대립의 관계로 보는 것이 아니라 서로 중첩될 수 있는 관계로 보아야 하며, 생태적 지속성에서 '생태적'의 의미는 관계성으로 이해되어야 한다. 지속성이란 변화하는 어떤 것과 그것의 변화하지 않는 것과의 관계로 규정된다고 하겠다. 그리고 생태적 지속가능성이란 변화하는 생태계를 구성하는 존재(혹은 존재자들의 관계)와 그것의 변화하지 않는 생태계 존재 전체(내지 총체적 관계)의 관계라고 정의 내려져야 한다. 따라서 생태적 지속가능성에서는 인간과 생태계라는 두 축의 관점에서 상호의존성(network), 지속성(sustainablity), 책임성(responsibility)의 3 요소, 즉 인간과 자연의 상호의존, 생태적 관계의 지속, 그리고 이에 대한 인간의 책임이 중요하다. 그리고 생태적 지속가능성의 의미에서 존재와 존재관계의 지속, 변화하는 지속가능성, 존재의 비존재에 대한 우위, 생명들 간의 연대성에 의거한 상호의존성이 중시되어야 할 가치가 된다.
