  • This study investigated whether top-down information influenced the filing-in of the blind spot. Two potential stimuli, which could fill in the blind spot, were presented at the location of the blind spot. When the two stimuli competed against each other to fill in the blind spot with equal probability, the depth-context of one of the stimuli was manipulated. We used an overlapping cue as our depth-context. Participants' task was to report the relative depth of a target presented in the blind spot. We found that the overlapping rue influenced the frequency of reported depth. These results, however, were nor observed in the off blind spot. These results suggest that top-down information such as an overlapping cue influences the filing-in of the blind spot.

  • This paper is about interactional characteristics of a middle school student's conceptual ecology in the context of conceptual change. A case study in this paper shows that: (1) there is interacted with three characteristics(conceptions, past experience, and explanatory coherence) within conceptual ecology; (2) the interactional characteristics of conceptual ecology have significant affects on the difficulties of conceptual change. Implications of this case study are that: (1) teaching for conceptual change should start at the certain site related to subject-matter task within students' conceptual ecology; (2) Students' inconsistent explanations could be used as the clue of conceptual change; (3) Past experience is the important area of conceptual ecology research for understanding learners.

  • 북항 재개발사업에 대한 기대와 관심은 항만시설의 기능성과 효용의 차원과 나란히 지역민의 정체성에도 깊이 뿌리닿아 있는 문제다. 이러한 의미에서 북항의 이슈와 함께 해항도시는 자신의 항구적 문화적 전통과 정체성을 어떻게 유지하며 발전시켜 나가는가라는 근본적이고도 광범위한 의문이 자연스럽게 제기된다. 본 연구에서는 이러한 논의의 확장과 심화를 위해, 독일 함부르크의 사례를 살펴볼 것이다. 함부르크의 슈파이허슈타트와 발린슈타트, 그리고 하펜시티는 도시를 의미하는 슈타트, 시티라는 명칭을 통해서 그 공간이 단지 하나의 건물, 장소에 머무르는 것이 아님을 암시하고 있다. 본 연구는 슈파이허슈타트의 경우는 함부르크 원도시와 일종의 제유법적 관계로서 읽고자 한다. 이러한 의미에서 슈파이허슈타트가 건설된 역사적 사회적 맥락을 논의하고, 이러한 맥락이 어떻게 공간적 시각적으로 확인될 수 있는가를 슈파이허슈타트와 원도심간의 교각을 통하여 확인해 볼 것이다.

  • Emergent process or behaviour can be seen in many places, from any multicellular biological organism to traffic patterns, cities or organizational phenomena in computer simulations. Similarly, the concept of 'Green IT' refers to the way complex systems and patterns arise inevitably among groups due to environmental concerns in real world. Green IT has good possibility to evolve as very chaotic system, in which the number of interactions between components increases geometrically with the number of components, thus potentially allowing for many new types of behaviour to emerge. However, when Green IT system regards as a complexity one, there exits some attractors to derive and control the system. In this context, this paper presents a new model based on type-2 fuzzy logic system to identify and assess the attractors of Green IT system which correspond to Reach-Richness matrix of Green IT.

  • When two objects are tying in the same visual direction there occurs abrupt depth change between two objects, which is against the assumption of the computational model for stereopsis on the surfaces in a natural scene. For this reason, this stimulus configuration is popularly used in the studies for the effectiveness of the constraints employed in the computational model. Contrary to the results from two nails (or objects) tying in the same visual direction, the two different surfaces from random-dot stereogram (RDS) in the same situation can be seen simultaneously in the different depth. The seemingly contradictory results between two situations my reflect the different strategies imposed by binocular mechanism for each situation during binocular matching process. Otherwise, the surfaces tying in the same visual direction is not equivalent situation to two objects tying in the same visual direction with regards to matching process. In order to examine above possibilities, the stereoscopic depth of the surface was measured after manipulating the visual direction of the surface elements. The visual direction of each dot pair from different surfaces in RDS (in Experiment 1) or the visual direction of line (hawing rectangle with regard to that of the vertical line (in Experiment 2) was manipulated. The stereoscopic depth of the surface was found to be varied depending on visual direction of the surface elements in both RDS and line hawing stimulus. Similar to the results from two nails situation depth of the surface was greatly reduced when each surface element was tying in the same visual direction as that of the other surface element or the other object. These results suggest that binocular mechanism imposes no different strategy in resolving correspondence problem in both two objects and two surfaces situation. And the results were discussed in the context of usefulness of the constraints employed in the computational model for stereopsis.

  • 비검측공 시험법을 현장타설말뚝의 건전도 평가 목적으로 적용함에 있어서 시험법의 적용성을 향상시키기 위한 연구가 진행되어 오고 있다. 본 논문에서는 같은 맥락에서 수행되어 온 일련의 해석적 연구 결과 중 시험법의 해상도에 관한 문제와 말뚝 주변 및 선단지반의 강성이 비검측공 시험결과에 미치는 영향에 관해 다루었다. 본 논문에서 수행한 연구결과에 의하면 충격응답기법의 해상도를 평가하기 위해서는 말뚝재료에 대한 지반의 강성비($V_{s}$ /$V_{c}$)와 말뚝의 길이에 대한 직경의 비(L/D)에 의존하는 기존 평가기준에 부가하여 말뚝의 상대적인 체적변화가 필히 고려되어야 한다는 결론을 얻었다. 한편, 말뚝이 수평으로 층이 진 주변 지반을 통과하여 말뚝선단부를 지지하는 지반(선단지반)에 근입되거나 지지되는 경우에 말뚝의 자유단 혹은 고정단 경계 조건은 주변 지반과 선단 지반의 강성비와 선단 지반에 대한 말뚝의 근입깊이에 따라 변화한다는 사실을 규명하였다. 말뚝의 건전도 평가 시에 사용하게 되는 말뚝의 공진주파수가 이들 조건에 따라 변화하므로 결과적으로 시험결과분석에 있어서 이들 영향이 필히 고려되어야 한다는 결론을 얻었다.

  • This study aims to analyze why South Korea has not used audit system but examination system and suggest policy reform for the system on the institutional context perspective. Institutional context is structured down to institutional legacy, motives, institutional constraints, actors' roles, and changed institution. I researched the literature on the subject and collected research materials from the Department of the Treasury and Audit Office website of New Zealand, Australia, United Kingdom, United States and South Korea. These were analyzed using for suggesting realistic and effective policy. Analysis showed that South Korea has used examination system due to institutional constraints and tried to increase reliability of financial statements by enlarging the meaning of examination, strengthening the ability of the Board of Audit and Inspection, enacting government examination standards, and making a comprehensive public announcement. Comparing with other countries where government audit systems are applied, there are still some vulnerable points in South Korea. In order to make up for the shortcomings, this study suggests several points: strengthening the ability of actors; systemizing internal control; expressing opinion; making a more comprehensive public announcement. It would be desirable for making further detailed studies of the points.

  • Socioscientific issues (SSI), by their nature, are conceptually embedded in technology. Previous research reported that nature of technology (NOT), unlike nature of science, was quite explicitly manifested in SSI decision-making, and NOT could be a promising construct for promoting SSI reasoning. In this study, authors introduced an integrated conceptual framework for NOT, which consisted of four dimensions (i.e., artifacts, knowledge, practice and system) as diverse modes of technology. We adapted the framework to investigate students' conceptualizations of NOT in the context of various SSIs. Data was collected from 45 college students enrolled in a liberal arts course on science and technology. The students participated in a team project, where they prepared and led discussions for SSI topics in class. Seven topics concerning SSIs were selected by students themselves. The preparation and class discussion of each student group were audio-recorded, and final reports were also analyzed. As a result, NOT sub-components in the dimensions of artifacts and system were explicitly represented in most contexts of SSI with various ranges of understanding. Other sub-components under the dimensions of knowledge and practice were rarely or implicitly shown in the discussion. The depth of students' understanding on NOT varied. Implications for science education were discussed.

  • This article analyzes biographies of women participants in Miryang struggle against 765㎸ transmission tower and finds that the experience of state violence under the ideological conflicts works the biographical context of participation in environment movement. The cases analyzed in this article disclose the family member's experience of state violence and their trauma through the participation in social movement. And they legitimize their family member's life, heal their trauma, and live a new life by the social movement participation. But the power of healing trauma comes from solidarity and support in social movement. Findings of this article imply that experiences of state violence have influence on the formation and development of various Korean social movements and we need more solidarity and democracy for healing the trauma occurred by state violence and concealed in individual memory. Findings of this article also suggest the importance of biography documents. Biography documents can contribute to widen and to deepen understandings on the social interaction and social history, because they are the document about people's experience who are excluded from the official history and character culture. Moreover biography documents can compensate the official documents, because they can offer the context to the social actions in the official documents. More accumulations and analyses on biographies can serve to widen and to deepen understanding and explanation of Korean society having multilayered exclusion in the process of the compressed modernization and the history of national division.
