Memory and schema are very similar in terms of human accumulated mental and physical experiences. However, while memory has more personal aspect, schema discussed in this paper has more collective aspect. Schema has been developed through different generations and times, and has become a specific psychological or visual element(s) that can be applied to various fields, such as all, design and architecture. This study focuses on Aldo Rossi's architectural design characteristics based on his 'Autobiographical Concept' as well as personal schema. 'Autobiographical Concept' is the crucial structure supporting Aldo Rossi's distinctive formalization and spatialization. 4 case projects were comparatively analyzed by the 5 elements included in 'Autobiographical Concept'. It was not easy to relate each element to a specific design aspect because the 5 elements are somehow theoretically and conceptually inter-connected each other. Even though it is very difficult to directly relate a conceptual element with a real spatial element, it is found that the 5 elements have some differences in the spatialization process. Thus, in the conclusion, this study attempted to show the unique characteristics of the Aldo Rossi's architectural design process based on his 'Autobiographical Concept'.

The primary purpose of this study was to investigate the validity of a component model of gender role and differences in children's gender concepts with age and sex. The secondary purpose was to investigate the relationship between children's gender schema and memory as well as preference for gender related task. 181 children were interviewed about gender concepts and gender related tasks. Results indicated that three dimensions of the component model (i. e., gender label-component links, within-component links, between-component links) were significantly related to each other. The mean scores of gender role knowledge and attitude were different with age but not with sex. The results of the regression analysis showed that children's age, sex, and gender role attitude explained both memory and preference for gender related tasks. The component model had better explanatory power than the simple model. The findings of the present study suggest that children's gender concepts are better described in terms of the component model than the simple model and may contribute to a theoretical rationale for gender schema theory.

There have been many studies to improve the performance of a database system focused on modifying data structure, data partitioning, and materializing strategy. The main contribution of this study is to propose a new alternative towards improving database performance by designing single table schema or processing queries virtually in main memory space. Material Requirement Planning(MRP) part explosion process has shown almost 2 times shorter under DB schema we suggested, and even more than 10 times shorter when separating and filtering policy of DB archiving process are assumed. Several experimental results are shown to illustrate the excellence of our solution.

The purpose of this study aims at the development of architectural design thinking which has been studied in the Kant's Epistemology to examine the Schema theories. In this point of view, the related theories are reviewed through Expression Form, representation of architectural knowledge and so on. One of these words, the Schema that formed by transcendental an Experience and Memory of transcendental an Experience, not only Play an important Part in the designer's thinking system about a specific problem but also appeared by distinctive features(image) and included by connotation as like a designer's ideology. Speaking briefly, thinking of a designer familiar with us as abstract confusion can be confined such methodological tools as schema, and image, etc., which we can easily understand the relationship among them through mechanism of Kant's [Concept-Schema-Intuition]. Evidences collected from case studies and its application on architectural design yield following results. First, design thinking can be defined as Kant's Epistemology composed of the schema and its extended factors(architectural-schema). Second, design thinking can be revealed different characteristics depending on the degree of the schema and architectural-schema. Lastly, the methodology will be proposed after application of the result to architects' works.

An IFC file is dependent on the IFC schema. Because of this relationship, most IFC-using software reads and interprets the IFC File by employing an early binding method, which uses a standard IFC schema. In the case of most open sources, early binding methods using standard IFC schema have a problem that they cannot express extra information of IFC File out of extended IFC schema. Also, in the case of previous studies, they suggested schema extension, such as adding attribute information to the schema, rather than the interpretation of IFC File. This study research on method of extracting shape and attribute information was conducted by analyzing the IFC File produced through the Port schema, which is an extended IFC schema. Three objects were created using the reference relationship between the Port schema definition and the IFC entity, and, at the end, the three objects were combined into one object. It has been confirmed that the shape and property data were express properly while delivering the combined object to the viewer. The process is possible because of the method of matching IFC schema and IFC File, which is dependent on IFC schema but not early binding method. However, this method has some drawbacks, such that contemporaneously generated many objects consume many memory spaces. Future research to investigate that issue further is needed.

The effects of schema on accurate and false memories of items in a scene were investigated in two experiments: Recognition of items in a scene was tested immediately in Experiment 1 and three days later in Experiment 2. In both experiments, the following three variables were manipulated: Exposure time (250ms or 10000ms), picture mode (completed pictures or scrambled pictures), and manipulation mode (missing item or substituted item). Experiment 1 had yielded three important results: First, although accurate memory for presented items got increased when the exposure time was longer, false memory of the critical lures was not changed. Second, false memory of critical lures in the missing condition, where there was not any conflict between verbatim information and gist information, was higher than that of the substituted condition, where verbatim information of the item that replaced the lure was in conflict with the gist information. Third, accurate memory for atypical items in the substituted rendition, which had replaced the critical lures and in conflict with the schema, was higher than that in the missing condition. In Experiment 2, recognition test were administered 72 hours after the participants saw the picture. The three effects mentioned in Experiment 1 had disappeared in Experiment 2. The results of Experiment 2 might be due to the selective weakening of verbatim information compared to the persistence of the gist (or schematic) information. The results of Experiments 1 and 2 showed that false memory of critical lures is more persistent than the accurate memory of non-critical information. Theoretical implications of the results were considered in terms of the function of the verbatim and gist information.

Two experiments examined the visual memory distortion by presenting 170 subjects with wide-angle views of four scenes on monitor screen. Retention interval of 0, 1 and 48 hours tested in reproduction and recognition experiment. The results of reproduction showed that the subjects tend to magnify the foreground and background of scenes compared to the real input (scene) for all retention intervals. The viewers recognized mure wide-angle views for the same scenes at the retention interval of 1 and 48 hours. These results demonstrated boundary extension is not a robust and unidirectional phenomenon but boundary contraction can be occurred with wide-angle views. The results also suggested that boundary contraction is the product of the activation of a memory schema hypothesis: In memory the representation moves toward a prototypical view and prototypical object size.

We propose a probabilistic design method and performance analysis in the area of dynamic data structures. We assign two stacks to a block which consists of m contiguous memory cells. Frequencies of delete and insert operations are not fixed, but depend on stack heights. We present various probabilistic schema and a rigorous performance analysis for a random memory allocation. Especially, stack coillision problem is studied and exponential increase of the mean of collision time as mlongrightarrow$\infty$is showed. We also present general mathematical schema which can be applied to the performance problems of finite automata and other computer information systems.

Viewers remember seeing more of the scene than was present in the physical input: an illusion known as boundary extension. This study examined the aspects of the distortion by presenting 69 subjects with wide-angle views of four scenes. Results of recognition and reproduction test showed that the boundary extension is not a unidirectional phenomenon. On the contrary, boundary restriction and foreground extension were observed with extreme wide-angle views of scenes. Results support the hypothesis that boundary restriction and foreground extension were mediated by the activation of a memory schema during picture perception.

XML is an emerging internet standard for data representation and exchange on the web. Recently, many researches on storing XML documents are in progress. Since XML documents have an implicit semantic schema, it is difficult to store XML data into a DBMS or File System. This paper introduces XDOM, object repositories for the DOM object, which stores an object for persistency support. As XDOM does not require the burdensome design of a fixed schema unlike the legacy DBMS, can store schema-less XML documents. And it can help XML applications to access the DOM object transparently from the object repositories below memory. XDOM introduced in this paper is implemented in pure Java and evaluated using experiments.
