  • A multiple criteria model for the facility layout problem considers both of the quantitative, the cost of the work flow, and qualitative, the closeness rating score, aspect. Rosenblatt, Fortenberry & Cox and Urban have developed multiple criteria models that consider both of the quantitative and qualitative aspect. Fortenberry & Cox's multiplicity model penalizes facilities with undesirable closeness rating and high work flows more than those undesirable closeness rating and low work flow between them to contribute to the objective function regardless of the closeness rating between these facilities. In this paper, it is intended to develops a improved multiple-criteria facility layout model considering the function for maintaning the distance between facilities.

  • This study explores the trends and implications of social welfare qualitative research in Korea. The results are follows. At present, social welfare qualitative research is entering in the quickening period. The characteristics of configuration of social welfare qualitative research in Korea are overwhelming inferiority in post-positivism and heuristics, wide differences between universities in metropolitan area and in local area at the aspect of amounts of qualitative research products, rapid increase in the interests of qualitative research in doctoral candidates, and distinguishment of doctoral candidates as a leader group in qualitative research. The results of critics of qualitative researches are follow: 1) initiative of naturalistic interpretism 2) inclination of methodicism 3) poorness of critical themes 4) propensity in grounded theory. These trends of social welfare qualitative research in Korea, in spite of the limits, have various implications: 1) Trying to critics of social welfare knowledge based on positivism and formation of opposing discourse to positivism 2) diversification in paradigm of inquiry 3) spread of narrative thinking of social welfare phenomenon.

  • Numerical method is applied to predict the time variation behavior of flammable mixture formation in a two dimensional enclosure from the beginning of gas leak. Additionally experimental method is used to consider qualitative aspects. Characteristics of flammable mixture formation such as distribution of flow and fuel mass fraction at various locations in the enclosure are determined for the following parameters: the various locations of leak at the bottom and aspect ratio of the enclosure. In the case of gas leak with small leak velocity from the bottom of enclosure gravitational force affects the formation of flammable mixture. Aspect ratio of the enclosure also affects the formation of flammable mixture. The volume of the region of recirculating flow is dominant factor affecting the formation mixture.

  • In this study, we intend to integrate the database(DB) method into one logical structure that is related to damage such as cause and type of damages occurring in the DMZ area. We divided the DMZ members into two types, which are classified into qualitative and quantitative aspects based on the current status survey for three years as a study of database construction, So that the actual data can be utilized in future restoration. The database construction through each restoration direction regarding the type of DMZ corruption is as follows. First, we recognized the necessity of restoration of the damaged area of the DMZ, and approached it as a plan to select the damaged mark. Second, DMZ database reconstruction can be used as a restoration of damages, suggesting more information and restoration type through building an ecological database for education and research. Third, in order to maintain and restore restoration of damaged areas continuously at the national level, it is necessary to institutionalize guidelines for reasonable internal restoration in the national level as data that can be credited externally and can be acknowledged as the latest data.

  • Scale scores for cognitive domains have been used as an important indicator for both academic achievement and clinical diagnosis. For example, in education, Cognitive Abilities Test (CogAT) has been used to measure student's capability in academic learning. In a clinical setting, Cognitive Impairment Screening Test utilizes items measuring cognitive ability as a dementia screening test. We demonstrated a procedure of generating cognitive ability test items similar as in CogAT but the theory associated with the generation is totally different. When creating cognitive test items, we applied automatic item generation (AIG) that reduces errors in predictions of cognitive ability but attains higher reliability. We selected two cognitive ability test items, categorized as a time estimation item for measuring quantitative reasoning and a paper-folding item for measuring visualization. As CogAT has widely used as a cognitive measurement test, developing an AIG-based cognitive test items will greatly contribute to education field. Since CLASS is the only LMS including AIG technology, we used it for the AIG software to construct item models. The purpose of this study is to demonstrate the item generation process using AIG implemented within CLASS, along with proving quantitative and qualitative strengths of AIG. In result, we confirmed that more than 10,000 items could be made by a single item model in the quantitative aspect and the validity of items could be assured by the procedure based on ECD and AE in the qualitative aspect. This reliable item generation process based on item models would be the key of developing accurate cognitive measurement tests.

  • This paper investigated the teaching and teaming of contents-related graphing in Korean secondary textbooks and suggested the improved methods of graph instruction through this analysis. reification-the case of function, In Harel, G., Dubinsky(Eds.), The Concept of Function : Aspects of Epistemology and Pedagogy Textbooks are analyzed from the viewpoint of the proportion of graphing contents, their sequencing, the proportion of each domain in graphing activities (interpretation vs. construction, quantitative vs. qualitative aspect, local vs. global aspect) and tasks (prediction, translation, scaling), and the difference in the graphing contents between the sixth and the seventh curriculum. This analysis demonstrates that graphing contents are increasing in textbooks, therefore the high school textbooks appear in almost every content area. The graphing activities concentrate on the construction, the quantitative aspects, and the local aspects, and are gradually focusing on the interpretation and global aspects of high school textbooks. Furthermore, most of graphing tasks favor translation. In contrast, the current seventh curriculum includes a balance of interpretation and construction activities and has more global aspects than the sixth curriculum based textbooks; however, the qualitative approach still rarely appears. For the graphing tasks, translation is still prevalent, but the importances of prediction tasks based on graph have increased in comparison with the sixth curriculum textbooks. Further, the seventh curriculum based textbooks are designed to stimulate more dynamic graphing instruction by introducing new tools such as graphing calculators and computer software. We suggest that the qualitative and global aspects should be emphasized in early graph instruction, a variety of graph activities in realistic contexts should be performed, and educational technology such as graphing calculator and computer can be efficient to implement these ideas.
