The purpose of this study is to provide mathematical knowledge for supporting the didactical knowledge on circular measure and radian in the high school curriculum. We show that circular measure related to arcs can be mathematically justified as an angular measure and radian is a well defined concept to be able to reconcile the values of trigonometric functions and ones of circular functions, which are real variable functions. Radian has two-fold intrinsic attributes of angular measure and arc measure on the unit circle, in particular, the latter property plays a very important role in simplifying the trigonometric derivatives. To improve students's low academic achievement in trigonometry section, the useful advantage and the background over the introduction of radian should be preferentially taught and recognized to students. We suggest some teaching plans to practice in the class of elementary and middle school for enhancing teachers' and students' understanding of radian.

This study focuses on establishing theoretically-reasonable framework of evaluation areas and items for the informatization program and analyzing the weights for each area and item by means of the AHP. To obtain the goal of this research, firstly, based on broadly reviewing previous literature and logical reasoning, the evaluation criteria were Identified and conceptualized, which were 3 evaluation phases, 5 evaluation areas, and 22 evaluation items. Secondly, The data used for calculating the weight values for the evaluation criteria were collected from 48 academic and practical experts in the field of the informatization program promotion using internet survey. Thirdly, the relative weights among evaluation phases, evaluation areas, and its items were derived by AHP analysis. The findings of this study are thought not only to be useful as a practical guideline in performing evaluating the informatization program but also to provide significant basis for constructing the theoretical framework of evaluating method and management of the informatization program.

The customer churn and the forecast of customer churn have been important research topics for a long time in the academic domain of customer relationship management. The customer value is studied to construct a gap model based on dual customer values; a basic description of customer value is given, then the gaps between products and services in different periods for the customers and companies are analyzed. The main factors that influence the perceived customer value are analyzed to define the "recognized value gap" and a gap model for the dual customer value is constructed. Based on the dual customer gap a con-ceptual model to determine potential churn customers is proposed in the paper.

Due to the promotion based on the recent research evidences that support benefits of breastfeeding, the proportion of breastfeeding mothers have steadily been increasing in the industrialized countries(60-90%). The purpose of the present review was to evaluate the recent findings on the nutritional values of breast milk and immunological benefits of breastfeeding in order to promote the breastfeeding practice in Korea. Research findings supported the concept that the breast milk has a lasting effect on the development of digestive and immune systems. Most of the works assessed whether breastfeeding enhanced protection against infection as well as decreased risk for certain allergic disorders.

In this study, the analysis to the preference level on slope measuring instrument of weight values on effect factors find out the reasonable monitoring on slope was performed, in which used AHP(Analytic Hierarchy Process) techniques. The results on professional group, such as the industry, academic, institute and government, analyzed that the very important effect factors, which were indicator of various collapse type, convenience of instrument management, The evaluation of preference level on the slope measuring instrument analyzed the invar wire extensometer which was high level at convenience of install, economical efficiency of install and convenience of instrument management.

This Paper will use various analysis tools that have not been used a lot by the existing researches, and also use the statistics of trade until August 2007 to measure and analyze the trade relationship between China and Korea. This study, which is basic study to studies to be conducted later, has been performed to establish effective economic cooperative relations between Korea and China by examining trade structure of the two countries through trade-related indexes. Therefore, this study has academic values as a theoretical study which can explain economic effects of the Korea-China FTA. However, as data used for this study was based on the data of the National Statistics Office in general, this study was executed with realistic limitations owing to lack of local data. I will supplement this later and do my best to conduct a precise study.

The purpose of this study is to identify the association of military looks with fascist aesthetics and to infer various aesthetic values of fascism expressed in military looks. The research method is documentary studies through the literature and academic papers, and examined masters' and doctors' theses, domestic and overseas books and fashion magazines, photographs and materials collected from the Internet. The facism expressed in military looks is as follows: First, nationalism, reflecting the current ideology of rebellion, appeals to the original national sentiment of the masses. Second, temptation implies that fascism tempts the mass using the nature of charisma rather than by force and, by doing so, accumulates mighty power without military force. Third, mythology is utilizing images and symbols of great appeal to people for absolute power beyond the concept of time. In order to express power for the effusion of emotional energy through the vision for realities and the magical power of images. Fourth, barbarism is always harbored in the conflict and confrontation of interests among ideas, economies, religions and classes on the other side of contemporary civilized society.

In a situation where the demand for creative talent creating new values and ideas is increasing day by day in the 21st century, students dealing with technology in the IT field have quite insufficient communication skills of materializing ideas and logically visualizing them. Therefore, the importance of systematic means of expression and methodology that can convey ideas more effectively and sensitively in the IT field is increasing. In this study, we recognized the importance of idea visualization education in the IT field by reviewing the relevant theory and examining creative thinking system cases and sought a more systematic visual communication method by investigating the awareness on creative thinking and expression. The results obtained in this study are considered to not only provide academic value as basic research in building new education programs in the IT sector in the future but be an opportunity for further research associated with creative talent training.
