  • Choosing automobile safety options is price-performance matter. The best fit options to buyer who has a certain driving habit are problem of MCDM (Multi Criteria Decision Making) because price of safety option, statistics of relating accident, consequence of accident, and driving habit are the multi criteria to be evaluated. In this paper, PROMETHEE-GAIA methodology is applied for solving this MCDM problem. The result shows that a different driving habit makes different choosing priority of safety options.

  • A method is proposed for the choice of the number of principal components in principal component regression based on the predicted error sum of squares. To do this, we approximately evaluate that statistic using a linear approximation based on the perturbation expansion. In this paper, we apply the proposed method to various data sets and discuss some properties in choosing the number of principal components in principal component regression.

  • The PID controller design and choosing PID parameters according to system response are proposed in this paper. Here PID controller is employed to control DC motor speed and Matlab program is used for calculation and simulation. Choosing PID parameters are demonstrated by several contrast experiments and a way for setting PID parameters values is discussed.

  • Optimizing transient response for both tracking reference signals and disturbance rejection is determined by the poles and zeros of the transfer function. Thus, optimal pole assignment and how should weighting matrix for the performance index be chosen is very important to achieve optimum transient response. This paper focus its attention on the choosing and analysis of weighting matrix for optimum pole assignment. Optimum pole assignment is defined for linear time-invariant continuous systems.

  • In this paper, we intend to find user's TV program choosing pattern and, recommend programs that he/she wants. So we suggest item dependency map which express relation between chosen program. Using an algorithm that we suggest, we can recommend an program, which a user has not saw yet but maybe is likely to interested in. Item dependency map is used as patterns for association in hopfield network so we can extract users global program choosing pattern only using users partial information. Hopfield network can extract global information from sub-information. Our algorithm can predict user's inclination and recommend an user necessary information.

  • The shape of an M-estimation function is generally determined in the sense of either/both maximizing efficiency of an M-estimator at the model or/and bounding the influence function of an M-estimator. We propose an empirical method of choosing a value of the bending constant in Huber's ${\psi}-function$, which is the most widely used M-estimation function when estimating the location parameter.

  • Consumers require various quality characteristics including safety. The reduction of risk concerned on product safety becomes urgent issue in leading companies. The strategy for customer satisfaction by choosing attractive quality characteristic is not enough for risk reduction in view of producer. This paper presents a method for choosing quality characteristics and risk characteristics by integrating QFD based on quality requirements and AHP based on safety requirements, also shows its application for complex equipment.

  • We propose a cross-validatory method for the choice of the number of principal components in principal component regression based on the magnitudes of correlations with y. There are two different manners in choosing principal components, one is the order of eigenvalues(Shin and Moon, 1997) and the other is that of correlations with y. We apply our method to various data sets and compare results of those two methods.

  • Choosing to See: A Framework for Equity in the Math Classroom is a book intended to be a practical tool for teachers to build empowering mathematics classrooms for their students from marginalized groups. Pamela Seda and Kyndall Brown provide concrete guidance using seven key principles, the ICUCARE (pronounced "I See You Care") Equity Framework, to provide a pathway for teachers for how to meaningfully make their classrooms a more equitable space for all students.

  • Due to the fast changing social and physical environment, the clothing behaviour of elementary school students should have been changed. Since previous research was completed a long time ago, new research must be conducted to understand the relationships of the clothing behaviour of elementary school students in terms of the time of research, gender and grades. Third and sixth grades in Susan were sampled in 2002; the secondary data in 1988 was used. Factor analysis and Lisrel's group analysis were conducted. The results indicated as follows: 1. As there was an increased interest in clothes, the comfort of the clothes was decreased at the higher grades in 1988, and the low and high grades in 2002, and the clothes of boys in high grade increased in the manageability in 2002, but nor with boy students in the low grade neither all types of students in 1988. 2. As there was an increased manageability in clothes, all types of girl students became more independence in choosing their own clothes. However, boy students in the low and high grades only increased their independence in choosing their own clothes in 1988. 3. As there was an increased comfort of clothes, there was not a significant relationship with the independence of students for choosing their clothes concerning the gender, the grades and the period of research. 4. As there was an increased interest in clothes, the low grade girl and boy students in 1988 increased in their independence in choosing their clothes. However, the high grade boy students in 1988 significantly decreased their independence. Thus there are different results in the clothing behavior in the elementary school student concerning the time of study, gender and grades.
