Purpose : The purpose of study was to develop generalized validity evaluation methods and terms for Sasang type diagnostic tests. Methods : A generalized statistical evaluation model for Sasang typology was suggested and generalized validity evaluation indices were proposed with this model. Results : The usefulness of validity evaluations, such as sensitivity and specificity values, were confirmed by the systematic review of the data from previously reported studies. Conclusion :Major obstacles in the multi-facet analysis and systematic review for Sasang type diagnostic tests were discussed with this test validity study.

A multi-purpose polariscope is developed by applying an electro-mechanical control system to a diffused transmission-type circular polariscope. A conventional polariscope is only good for manual control of optical elements. The new polariscope system is devised to be controlled through two stepping motors and two magnetic clutches. The developed system has both functions of a conventional linear- and circular-polariscope. The new polariscope can be used not only for the point-wise measurement using Tardy compensation technique but also for the full-field fringe analysis using conventional and/or phase measuring techniques, if applicable.

Korea multi-purpose satellite-5 (KOMPSAT-5) is a low earth orbit (LEO) satellite scheduled to be launched in 2010. To satisfy the precision orbit determination (POD) requirement for a high resolution synthetic aperture radar image of KOMPSAT-5, KOMPSAT-5 has atmosphere occultation POD (AOPOD) system which consists of a space-borne dual frequency global positioning system (GPS) receiver and a laser retro reflector array. A space-borne dual frequency GPS receiver on a LEO satellite provides position data for the POD and radio occultation data for scientific applications. This paper describes an overview of AOPOD system and operation concepts of the radio occultation mission in KOMPSAT-5. We showed AOPOD system satisfies the requirements of KOMPSAT-5 in performance and stability.

Purpose - Product purpose for optimal values solution for synthesize evaluative criteria and optimize product design values. In addition, product designer has to consider the product design to conform to project, laws and regulations, authentication, from the product design stage. Research design, data, methodology - How to use an evaluative criteria model's imprecise market data by evaluative criteria research design; product mapping relationships between design parameters and customer requirements using product predicted value method. An evaluative criteria model and their associated criteria status, product evaluative criteria model of results. Results - Therefore, after the enterprise product design project analysis, effectiveness and the customer degree of satisfaction must be appraised to obtain the maximum value for the benefit on behalf of the implementation goals, the promotion product level and market competition strength. Conclusions - In multi criterion decision making (MCDM), using its searching software capacity to obtain the optimal solution.

The purpose of this article is to depict the relationship between the frames of leadership and the dependent variables such as job satisfaction, respect from subordinates, promotion, and effective attainment of unit objectives. To attain this purpose, four types of multiple leadership frame, such as structural, human resources, political, and symbolic frames were surveyed through questionnaire and analyzed by SPSS. The major findings are : 1) In general, the symbolic frame is an important factor having a stronger influence on job satisfaction, respect from subordinates, promotion, and effective attainment of unit objectives. 2) In details, the human resources frame shows a positive effects on job satisfaction and respect; the structural frame on effective attainment of unit objectives; the political frame, to a certain degree, on promotion; and the symbolic frame, especially on respect from subordinates, promotion, and effective attainment of unit objectives.

The purpose of this study is to examine the image­based atmospheric correction models using the data from Landsat Enhanced Thermal Mapper Plus (ETM+) that have quite similar spectral characteristics to the forthcoming Korea Multi-Purpose SATellite (KOMPSAT)-2 Multi-Spectral Camera (MSC), and the in-situ measured surface reflectance data during satellite overflight. The main advantage of this type of correction is that it does not require in-situ measurements during each satellite overflight. While substantial differences are present between Top-Of-the Atmosphere (TOA) reflectance and in-situ measurements, the results showed that Case 1 based on COST model gives most accurate results among three cases. The accuracy of Case 2 is very close to Case 1 and its values are smaller than in-situ data. No notable features appear between some bands in the Case 3 and in-situ data. It is expected from this study that if the current methods are applied to the IKONOS high resolution data, we will be able to develop the suitable atmospheric correction methods for MSC data.

Kindergarten children are engaged in the age of physical immaturity as well as the rapid growth. The indoor air contaminants that are proved to affect even the full grown adults are obvious to have no little influence to immature small children in a growth period. In May 2004, for the multi purpose facilities and newly constructed apartments, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. In Dec 2005, the law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. However, since the kindergarten takes none of the classifications, even the current condition is not grasped although it is directly connected to the health of growing children. Therefore, the study aims to analyze indoor air pollution of one selected kindergarten in Incheon city.

Recently, Radio Frequency Identification (RFID) cards have been charming increasing attention. In addition, the RFID card ensures high durability and ease of maintenance because it has no built-in contact. And the benefits of RFID cards over contact cards are primarily due to the increased transaction speed and convenience brought to the cardholder. In this paper, we have developed a RFID card reader for the multi-purpose applications. The vicinity card reader with large-screen to display user ID and card number for a kinds of applications such as entrance and attendance management system is suitable for the use with EM card and TEMIC card, featuring easy to mount and reliable quality. The read range of the proposed RFID card reader is 70cm. This paper also addresses current RFID technology in terms of systems and provides a look forward its future applications in the aviation environment using RFID smart card.

In the multi-purpose lathe, the design of tilting turret slide system has an important and critical role to enhance the accuracy of the machining process. Tilting turret unit is traveled by 3-axis slide systems. There is a need to design this part very carefully. In this research, the 3-axis slide system with tilting turret unit is researched with two approaches; The first is that 3-axis slide system is modeled and simulated usig ADAMS software. The dynamic behavior of this system is visualized by data graphs and dynamic animations. The first step of virtual prototype which makes it possible to design economically and effectively is developed.

This study aims to establish new architectural agenda for the existing middle school facilities responding to individualized interactive learning approach(IILA). First, it investigates the mechanism of new teaching methods and contents proposed in the national level curriculum and the province guidances. Secondly, it suggests the Quality and Quantity of new (multi-purpose) classrooms that should be built for operating new curriculum in the existing middle schools. Finally, it finally emphasizes the educational specification that should be prepared prior to planning school buildings.
