  • Elementary preservice teachers' understanding about the insect molt and metamorphosis was examined. Data were collected through the paper-pencil test of 448 junior students at a National University of Education. The instrument used was developed by Son(2003) and modified for the test. The results are as follows: First, Only 3.1$\%$ of students had a scientific concept on the molt periods in the insect life cycle. Students had an alternative conception that molt occurs either only in the larval period (29.9$\%$) or only in the period from pupa to adult (22.3$\%$). The percentage of the students thinking that molt occurs in the period from larva to pupa was low. Second, 98$\%$ of students stated that molt has to do with the larval growth, but 39.1$\%$ of students had an alternative conception that molt occurs after the larval growth at each instar. 25.1$\%$ had a conception that molt is related with the larval growth, but did not show any further understanding. Third, most students understood the correct meaning of metamorphosis. 34..2$\%$ of students had an alternative conception that metamorphosis occurs only in the period changing from pupa to adult, and only a few thought that it occurs in the period from larva to pupa. 24.8$\%$ of students had a scientific concept on the periods in which metamorphosis occurs. Fourth, some students understood the hatching process as molt in the sense that the egg shell is taken off (21.0$\%$), and as metamorphosis in terms of the appearance change from egg to larva (25.0$\%$). Fifth, 35.5$\%$ of students selected bees as an insect of incomplete metamorphosis, and 35.3$\%$ responded 'I have no idea', showing that they had poor understanding about the insect life cycle.

  • This study investigated the conceptualization and application of new concept of regional resilience with case study in Korea in order to promote more sustainable regional development strategies, while problematizing dominant regional competitiveness concept in the current regional development circle under the condition of stagnant growth and ever-existing crisis in these days. Through literature review, this paper found out that regional resilience is a useful concept both to understand dramatic regional changes and to promote new regional development strategies. Furthermore, the study formulated basic research topics and issues for regional resilience through reviewing existing research outcomes on the measurement and factors of regional resilience. Through case study of two macro city-regions in Korea, this study also found out that regional resilience patterns and processes are differentiated according to the place and its scale and that both regional industrial structure formed in a path-dependent way and regional competitive characteristics are all significant to understand the regional resilience patterns and processes.

  • To improve the environment of individual residential area, the uniform development of multiple dwellings through site should be avoided. As an alternative to a large scale development of the currently popular high-density and high-rise apartment buildings, which disintegrates and destroys existing communities, a new residential type that is applicable to the individual residential area should be developed. From the new residential type, even for short history of Korea of modem urban residence, a new concept of residence can be formed, changing from the concept of a temporary staying place to the concept of a stable residing place. Also, a gradual improvement that transcends time can be expected, and the present and past appearances can co-exist. This study was conducted to suggest a new residential type with unit blocks that can improve the physical structure of existing individual residential area without destroying the structure. That is, among the factors that comprise the individual residential area, this study will focus on the unit block with a medium role between a site and a mega-block, and will suggest a new concept of residential unit in order not to destroy its physical structure. The physical characteristics of the unit block will also be analyzed.

  • This study investigated the complex meanings of the concept of place and their periodical changes in the Korean architectural discourse. For that, the study surveyed almost every articles in majour 3 Korean architectural magazines during around 1990s, when the Korean architects and theorists concerned the 'place' as an alternative of the modernists' 'space'. 60 selected articles were organized in a table in a chronological order together with their keywords and category codes. The 8 categories reflecting 8 issues of 'place' were suggested in the study after the analysis of selected articles' contents. The categories were structured by two axes which were 4-grade scale axis influences by C. Norberg-Schultz' approach, and 'architecture-human' axis following the 'structure-action' division by A. Giddens. After the analysis of the diachronic and synchronic tables, the study tried to establish a structure model of the concept of place in Korean architectural context, which consisted of architectural terms such as environment, social system, context, identity, landscape, community, Materiality, and residence. This final result could be useful for both architects and theorists who might try to apply the idea of 'place' without erstwhile confusion on their design or research by examining the detailed contents of the concept.

  • This paper aims to extract an ObjectProperty-UsageMethod relation, in particular the HerbalMedicinalProperty-UsageMethod relation of the herb-plant object, as a semantic relation between two related sets, a herbal-medicinal-property concept set and a usage-method concept set from several web documents. This HerbalMedicinalProperty-UsageMethod relation benefits people by providing an alternative treatment/solution knowledge to health problems. The research includes three main problems: how to determine EDU (where EDU is an elementary discourse unit or a simple sentence/clause) with a medicinal-property/usage-method concept; how to determine the usage-method boundary; and how to determine the HerbalMedicinalProperty-UsageMethod relation between the two related sets. We propose using N-Word-Co on the verb phrase with the medicinal-property/usage-method concept to solve the first and second problems where the N-Word-Co size is determined by the learning of maximum entropy, support vector machine, and naïve Bayes. We also apply naïve Bayes to solve the third problem of determining the HerbalMedicinalProperty-UsageMethod relation with N-Word-Co elements as features. The research results can provide high precision in the HerbalMedicinalProperty-UsageMethod relation extraction.

  • The recent concept of kitchen is likely defined as "Kitchen Culture" including the function of living room where all families make a conversation as well as a dinner, and it is becoming another type of the residential environment, deviating from the stereotype as only cooking area. Particularly the comfortableness of living room is closely associated with a receipt function of kitchen, and the sort & dimension & size of furniture and diversity of shapes playa more meaningful role for improving our life standard & comfortableness compared with the past, nevertheless this receipt study is carelessly handled in the first phase of construction. This Study is focusing on understanding the modern concept of kitchen where the open space concept is being introduced as more reasonable space concept, and on suggesting a solution for receipt-function of the modern kitchen concept connected with "L-D-K (Living room - Dining room- Kitchen)" space idea. In the Chapter 2 the concept of receipt and function of kitchen, the wide variety of kitchen utensils was checked up, and in the Chapter 3 the change of trends of kitchen area & receipt space was considered, and finally in the Chapter 4 the modern concept of kitchen was presented, by instancing overseas examples with receipt planning. As a consequence, the alternative of the receipt in the modern kitchen is to install an Ireland table or another type of receipt-available table (lower furniture) in the dead space between kitchen & living room for motivating smooth communication and convenient receipt, and that is the trend nowadays. Kitchen desires a rapid change. Through this kind of study it should be more researched that kitchen is not an independent space any more and lies in the mutual connection of L-D-K.

  • This study aims to find a way to realize gender identity in product design. After reviewing the present research, it was found out that it is necessary to extend notion of gender and to redefine the concept of gender design. Specific products were selected in order to analyze the characteristics of femininity. Refrigerators, which represent the femininity the best, were chosen and analyzed based on the graphic elements. As a result, the concept of gender have been used quite limitedly in a refrigerator. Since the stereotype of women has already been implicit, it was considered difficult to propose an alternative plan for realizing the extended concept of gender. Therefore, digital devices have been proposed for a potential alternative group. This product group, of course, has a limitation like the refrigerators. However, when functions, frequency of use, and use of space are considered in depth, It can be a possible group that holds the meaning of gender in design. This study is significant that it attempted to examine the possibility of convergence in identity and usability when the graphic elements of a product are constructed by gender design that considers the identity of a user through redefining the concept of gender.

  • Universal design is an approach to create environments and products that recognizes the diversity of users, regardless of their ability or age. Recently, old person and disabled person rapidly go on increasing in number. So, universal design concept becomes more and more important in product and environment, etc. In this study, we dealt with the universal design problem of microwave oven considering old persons. New design model for microwave oven was developed and evaluated using human factors approach. The principles of universal design was developed through literature survey and questionnaire survey for old persons, and then design alternatives were developed according to these principles. Two experiments were performed in this study. The purpose of the first experiment was to select final design alternative and the experiment was performed using rapid prototypes. The second one was a usability testing for the real model of final alternative. In this experiment, the real model was compared with the existing real product. As the result, the new design model was a little more excellent than the existing model in usability.

  • The combination of data warehousing and Internet technology produces a new concept - web warehousing. Due to the availability of web technologies and the need to make prompt decisions with timely information, web warehousing is emerging as a key strategic business weapon. Yet despite the many promising benefits of web warehousing, researchers have also identified several challenges, including scalability and availability. With the rise of the Internet and data centric computing applications, the use of new Storage Area Network (SAN) technology has been spotlighted for the possibility of a new data repository for web warehousing. In this article, the two new concepts of web warehousing and storage area networks are introduced. In particular, a SAN is discussed in detail as an alternative data repository to overcome the current limitations of web warehousing.
