The emergy concept was used to valuate the contributions of a tidal flat ecosystem included in the fourth stage reclamation plan for the Youngsan River area to the Korean economy. Emergy contributions of the ecosystem were compared with those of economic valuations performed on the same ecosystem. The tidal flat ecosystem contributed 3.55 million EmW/ha annually. This, however, cannot be compared directly with those of the economic valuations because both methodologies approach the valuation of ecosystems in different perspectives. The emergy methodology is a donor-based valuation in which what goes into making a product or service is measured, while the economic valuation is a receiver-based approach in which human receivers determine the value of an ecosystem product or service. An emergy valuation was conducted for the three ecosystem functions included in the economic valuations to compare the results of both methodologies on the same basis. Fishery production and pollutants removal contributed 9.86 million EmW/ha/yr and 0.88 million EmW/ha/yr, respective1y. The conservation value of the tidal flat ecosystem was 3.55 million EmW/ha/yr. Overall, the emergy valuation that try to include works of both human and nature on the same basis resulted in higher economic contribution of the tidal flat ecosystem than that calculated by the economic methodologies in which only human works are measured based on the willingness-to-pay of people. This study showed that the emergy concept could provide an alternative tool for policy decision-making regarding utilization and conservation of ecosystems by approaching the ecosystem valuation from a different perspective than that of economic methodologies.

This study was designed to examine the decision-making and family life satisfaction of the urban middle-aged housewives from the ecological perspective. The main purpose of this study was to investigate the effects of ecological enviornment variables(ie, natural physical-biological environment·social-cultural environment·human-built environment) and their dicision-making on their family life satisfaction. Also, it is to provide some fundamental information that helps to elevate the family life satisfaction of the unban middle-aged housewives. The subjects of this study were 305 housewives living in Seoul and Inchon area, whose age was from 40 to 59. The significant results were as follows: 1) Their decision-making was affected by the following variables in the order of health condition, fate-control orientation, husband’s support, monthly family income and the perception of the adequacy of household income. 2) The ecological environment variables which had an influence on family life satisfaction were the perception of the adequacy of household income, husband’s support, fate-control orientation, health condition and educational level. 3) From the regression analysis, the model was found to be highly significant, accounting for 44% of the variance. Thus, husband’s support was the strongest predictor variable.

공정제어시스템과 같은 복잡한 시스템을 감시하고 제어하기 위한 정보 디스플레이를 설계하기 위해 두 가지의 세부적인 설계문제를 효과적으로 다루어야 한다. 정보디스플레이에서 표현할 정보의 내용을 파악하고 조직화하는 문제와 그 표현할 정보를 시각적으로 잘 표현하는 문제로 구분이 된다. Ecological Interface Design (EID)는 두 문제를 다루기 위한 이론적 배경지식과 방법을 제공하는 정보디스플레이 설계의 틀이다. EID는 1990년대 초반에 그 개념적 틀이 소개된 이후에 그 유용성이 여러 작업영역과 직무환경에서 입증되어 왔다. 그러나 실제 현장에서 EID의 개념을 활용하는데 있어 큰 어려움으로 지적된 것이 정보의 시각화를 위한 실용적이고 구체적인 원칙과 방법이 부족하다는 점이었다. 또한 EID 개념의 활용에만 집중할 경우 효과적인 정보 디스플레이 설계를 위해 고려되어야 하는 다른 설계 문제들이 쉽게 간과될 가능성도 높다. 이 점은 아직도 EID의 실제적 활용성을 높이는데 큰 약점으로 지적된다. 이 논문에서는 EID의 개요와 장단점을 소개한 후에 이에 기반해서 정보 디스플레이 설계를 종합적으로 다루는 데 도움이 될 수 있는 방법을 소개한다. 특히 이 논문에서는 기능적으로 추상화된 정보의 시각화 및 추상화 관점에서 다른 단계에 있는 정보들간의 목적-수단 관계를 시각화해서 명시화하는 것을 강조한다. 또한 디스플레이 설계 요소에 기반한 설계 프로세스 및 관련 설계 원칙 및 지침의 적절한 활용도 강조한다. 이 논문에서 제안된 방법은 EID의 개념적 틀을 확장하면서 인간 중심적인 정보 디스플레이의 설계하는데 유용한 원칙과 방향성을 정립하는데 도움이 될 것이다.

This study aims to propose a conceptual design of information displays for supporting responsive actions under severe accidents in Nuclear Power Plants (NPPs). Severe accidents in NPPs can be defined as accident conditions that are more severe than a design basis accident and involving significant core degradation. Since the Fukushima accident in 2011, the management of severe accidents is increasing important in nuclear industry. Dealing with severe accidents involves several cognitively complex activities, such as situation assessment; accordingly, it is significant to provide human operators with appropriate knowledge support in their cognitive activities. Currently, severe accident management guidelines (SAMG) have been developed for this purpose. However, it is also inevitable to develop information displays for supporting the management of severe accidents, with which human operators can monitor, control, and diagnose the states of NPPs under severe accident situations. It has been reported that Ecological Interface Design (EID) framework can be a viable approach for developing information displays used in complex socio-technical systems such as NPPs. Considering the design principles underlying the EID, we can say that EID-based information displays can be useful for dealing with severe accidents effectively. This study developed a conceptual design of information displays to be used in severe accidents, following the stipulated design process and principles of the EID framework. We particularly attempted to develop a conceptual design to make visible the principle knowledge to be used for coping with dynamically changing situations of NPPs under severe accidents.

This paper intends to suggest the positive, ecological vision of sustainability in Karen Hesse's Out of the Dust that Billie Jo Kelby recovers herself through her readjustment of interior consciousness and outer environment in her tragic situations caused by the Dust Bowl. In spite of her desires for happiness and affluence of home, she loses her mother and brother, and her musical talent as a pianist, and lies in self-abandonment. But she finally raises up herself with her courage and patience, reconciliating with the nature and ameliorating the community by taking care of the devastated landscapes. Hence it is appropriate to approach the loss-recovery process of nature and consciousness with ecological solutions, The Dust Bowl breaks down human mind and body, and eventually leads to the situations of despairs and death. Hesse proposes the primary solution that humans should reconstruct their interior consciousness and participate in recovering the nature because humans are inevitably linked with nature. In this novel, the nature takes a dynamic and active role as a catalyst, reconciling the self with other humans and settling with the conflicting situations in history and culture. This verse novel as an active, self-ordering, and corrective process gives the more intense ecological message. As Hesse defines the setting of Dirty Thirties as a channel of energy, she creates the utmost effects of ecological process that human and environment are part of a total situation, representing the transactional formulation, each conditioned by conditioning to the other. Therefore Billie Jo takes her part as an interpreter and actualizes herself, understanding the nature with metaphor and symbol. Eventually Billie Jo realizes that she should rebuild her environment not out of the dust but in the dust, accepting the reality of Dust Bowl.

As cultural diversity has gained a great deal of attention and the social fabric of Korean society is redefined, the number of studies on multi-cultural family homes has been growing in the area of human ecology, but relevant research is rarely found on the subject of housing. While the emphasis of housing research is on multidisciplinary approaches and empirical research is highly valued, a theoretical and methodological platform for discussing the new rising agenda of multi-cultural family homes is lacking. The purpose of this study was to explore approaches to and to discuss the issues in research for multi-cultural family homes in terms of housing theories and multidisciplinary approaches. To understand the housing related needs of multi-cultural families, this study highlights social constructionism, the ecological perspective, and feminist epistemology. These three multidisciplinary approaches were useful for generating an ontological analysis of multi-cultural family homes. Further, this study highlights two housing related theories, the microsociological and housing pathways approaches, for dealing with multi-cultural family homes. In conclusion, the five approaches were useful for exploring issues in housing research on multi-cultural family homes with appropriate research methods like hermeneutics, quantitative, and qualitative methods, and field research. Insights into using perspectives and holistic approaches might be useful for solving the problems of multi-cultural family homes in Korea.

The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.
