This work was researched by practical methodology in-depth study of a subjectivity dimension study, in sloughing away a past habituation of functional quantity analysis on perception-effectivity and a habit of dietary life for effective health-promotion. The perception patterns be generated from this study were classified into three types in Q-method. They are as follows ; it is that divided into 'I[(n=9) : eating type in morning], II[(n=11) : type of no having a midnight meal], III[(n=9) : type of mealing after taking exercise]'. Like this, it found that is very different type all over. Finally, this paper is to examine an acceptance behavior about reception type on effectiveness and a habit of dietary life for effective health-promotion ; to make a proposal in a developmental and creative opinion about it.

This study analyzed the culinary arts major students' subjective perception toward capstone design subject which was thought by team teaching method through applying Q methodology. Generating future suggestions of the operation of the subject and finding common structure of students's responses are the main aim of this study. From the typological analysis, four types of common structures were found. There were Differentiation Curriculum Satisfaction Type(Type 1, N=14), Restaurant business plan Type(Type 2, N=5), Prefer franchise education Type(Type 3, N=3), Prefer menu development lesson Type(Type 4, N=3) and each type showed its own distinctive characteristics. In the future research, additional literature research and empirical study will be applied for adjusting and developing more sophisticate questions of Q methodology and analysing process for gathering diverse responses and specific analysis.

This article describes optimization for PGS(Patterned Ground Shield) of rectangular spiral inductor using Taguchi's Design of Experiment. PGS is decrease method of parasite component by silicon substrate among dielectric loss reduction method. Using taguchi's design of experiment, each parameter is fixed upon that PGS high poison(A), slot spacing(B), strip width(C) and overlap turn number(D) of PGS design parameter. Then we verified that percentage contribution and design sensitivity analysis of each parameter and level by signal to noise ratio of larger-the-better type. We consider percentage contribution and design sensitivity of each parameter and level, and then verify that model of optimization for PGS is lower inductance decreasing ratio and higher Q-factor increasing ratio by EM simulation.

This paper shows the Applied Q-learning Algorithm which supports selecting the waiting position of a robot and the part serviced next in the Flexible Manufacturing Cell (FMC) that consists of one robot and various types of facilities. To verify the performance of the suggested algorithm, we design the general FMC made up of single transfer robot and multiple machines with a simulation method, and then compare the output with other control methods. As a result of the analysis, the algorithm we use improve the average processing time and total throughputs as well by increasing robot utilization, reversely, by decreasing robot waiting time. Furthermore, because of ease of use compared with other complex ways and its adoptability to real world, we expect that this method contribute to advance total FMC efficiency as well.

A new approach to the analysis of horizontally curved beams is presented in this paper. The proposed method simplifies a two-dimensional structure into a one-dimensional structure just like a normal beam for structural analysis and, therefore, reduces the computational effort significantly.

This paper deals with the characteristic analysis & optimum design of Permanent Magnet Assisted Synchronous Reluctance Motor(PMASynRM) for Premium Efficiency Performance. The focus of this paper is characteristic analysis of d and q-axis inductances and torque according to magnetizing quantity of interior permanent magnet for PMASynRM. The d and q-axis current component ratios, load angles of a PMASynRM are investigated quantitatively on the basis of the proposed analysis method and the experimental test. Comparisons are given with output characteristic curves of normal SynRM and those according to the load in PMASynRM, respectively. And optimum design of PMASynRM is performed by Response Surface Methodology(RSM).

In this paper, torque characteristics analysis of Synchronous Reluctance Motor with the cylindrical rotor type by winding function theory(WFT) is described. The stator is same as one of the induction motor. From the d-axis, q-axis flux density distribution, to calculate self and mutual inductances needed to calculate the torque of the machine by using winding function theory the new equivalent geometry of rotor was proposed. D-axis, q-axis flux densities, self inductance and torque characteristics were obtained. From the comparison with results of finite element analysis the proposed method was verified.

In this paper, the application of object-oriented Data Model to develop a multibody dynamic system, called O-DYN, is introduced. Mechanical components, such as bodies, joints, forces are modeled as objects which have data and method by using object-oriented modeling methodology. O-DYN, a dynamic analysis system, based on the object-oriented modeling concept is made in C++. One example is analyzed through the O-DYN, It is expected that the analysis program or individual module constructed in this paper would be useful for mechanical engineers in predicting the dynamic responses of multibody systems and developing an analysis program

Common problems have been observed in the existing Information Requirements Analysis (IRA) methodologies such as BSP(IBM), CSF(Rockart), or ISP(Information Engineering), etc. These methodologies require too much time and human resources for the IRA process, involves high complexity, and their IRA outcomes are frequently biased by the subjective views of the people involved. In this paper, we introduce a new methodology for the enterprise wide information requirements analysis utilizing templates and nine closed-ended questions. Extending the BIAIT(Business Information Analysis and Integration Technique) method, this methodology presents nine question about each firm's order type(7Q's for customer side and 2Q's for supplier side) to derive information processing characteristics of the firms. As the central component of this methodology, data and process templates for the manufacturing industry were established. To validate the methodology, suitability of the data and process templates were examined through six real world business cases.

This paper deals with analysis method of single-phase line-start permanent magnet motors. Unbalanced magnetic fields produced by single-phase input make analysis difficult. To solve this unbalanced magnetic fields, this paper proposed symmetrical components transformations as well as d-q axis ones. Parameters in d-q voltage equations were calculated by Finite Element Analysis.
