Secondly, was subjected important for atmosphere composition and was required strategy consideration for stable job recognition. Third, was operated affirmative to recognition about separation and was increased to job satisfaction according as a colleague relation and team work. Fourth, was increased to comparative separation propensity in case that high job satisfaction. Therefore it is required interesting labor item and treatment development about personal evaluation.

The purpose of this study is to analyze the phenomena of the thermally-induced vibration for the flexible space structure due to abrupt change of radiation heating circumstance using the numerical analyze and experiment test. In order to verify this structure, numerical approaches on the simplified flexible tube were compared with experimental test results at the ground experimental facility In this analyze, it was found that the thermal deformation occurs firstly due to fast radiation heating of flexible structure and then the thermally-induced vibration would be induced due to small periodic change of temperature. According to comparison of numerical and experimental result, in case of no tip mass, the first mode vibration by the numerical analyze was O.78Hz same as that of the experimental result However in case of increase tip-masses of 8g l6g, 50g and 100g, the first modes vibration theoretical analyze were 1.75Hz, 1.3Hz, 0.87Hz and O.73Hz, in decrease trend respectively and those by experimental test were 234Hz, 1.5Hz, O.78Hz and O.78Hz in decrease trend respectively Although using the simpled equation for the estimation, the estimation results were similar to experimental results.

The purpose of this study is to analyze traits of transport goods by Rail. Now, many kinds of shipper transports their goods by the Rail. but Rail transport system did not satisfied their requirements. In order to analyze shippers desire, make a marketing strategy for more efficient rail transportation system, make up a questionnaire on transport by rail and analyze by using AHP method.

The purpose of this research is to analyze the planning characteristics based on the physical quality indicators and the users' satisfaction of parking space in apartment housing through the case study of 36 housing estate samples which were built in 1994-1998. The contents of this research consists of three main parts. The first part is to analyze the characteristics of residential environment based on the quality indicators of parking space in apartment housing. The second part is to analyze the correlation of quality indicators of parking space and development conditions in apartment housing. The third part is to analyze the correlation of users' satisfaction and physical quality indicators of parking space, and to propose the planning methods which increase the quality of residential environment of parking space in apartment housing.

This study aimed to analyze the characteristics of good science teachings regarded by preservice elementary school teachers. It also aimed to suggest a direction of peer teaching practice to help preservice teachers' professional development. Adjacency pairs were adopted to analyze the characteristics of good science teachings. The results showed that pre-service elementary teachers were accustomed to adjacency pairs. Almost of their discourse were organized by adjacency pairs. 'Question-Answer' and 'Request-Accept' were mainly used in science classes by pre-service elementary teachers. Based on the findings, the study suggested science teacher educators to provide chances to analyze exemplary science teachers' science class or chances to analyze their science teachings in terms of competence of science classroom discourse.

AC machines are in wide use in industry and d-q transformation from 3 phase of a, b, c is commonly used to analyze these kinds of machines. The equivalent circuits of d and q axis are, however, generally cross coupled and difficult to analyze. In this study, a modeling technique of AC machine including induction and PM synchronous motors using matrix vector is proposed. With that model, it can not only explain the AC machines physically but also make it simple to analyze them. The separating process of d and q components is not needed in this model and this model can be applied to analyze asymmetric motors like IPMSM machine. With this technique, the model becomes simple, easy to understand physically, and yields results that are the same as those from other models. These simulation results of the proposed model for induction motor are compared with those of other models to verify the method proposed.

The internet is already a part of life. It is very convenient and people can do almost everything with internet that should be done in real life. Along with the increase of the number of internet user, various network attacks through the internet have been increased as well. Also, Large-scale network attacks are a cause great concern for the computer security communication. These network attack becomes biggest threat could be down utility of network availability. Most of the techniques to detect and analyze abnormal traffic are statistic technique using mathematical modeling. It is difficult accurately to analyze abnormal traffic attack using mathematical modeling, but network simulation technique is possible to analyze and simulate under various network simulation environment with attack scenarios. This paper performs modeling and simulation under virtual network environment including $NGSS^{1}$ system to analyze abnormal traffic-flooding attack.

Marked Petri Net(MPN) is used to analyze communication complexity with respect to the maximum number of concurrently active rendezvous. But, because it cannot represent timed & probability characteristics explicitly, it is not used to analyze the new execution time of complexity with respect to the communication. Thus to effectively analyze that execution time complexity, we propose Ada Tasking Structure Nets (ATSN) introduced restrictive conditions : net reduction rules, execution time, and probability. Finally, we show the powers of analyze of communication complexity with ATSN.

This study in an attempt to analyze the child's readiness for school and to pursue the facts that influence the readiness. the child's readinees for school was analyze on the developmental tasks in terms of physical, intellectual, social and moral development of first graders. On the facts that influence the readiness, age, sex, home environment and preschool experiences were surveyed. Ⅰ. Objectives 1. To survey the actual developmental conditions of physical, intellectual, social, and moral development of first graders. 2. To analyze the differences of school readiness in of sex, age and birth order. 3. To analyze the influence of home environment and preschool experience upon readiness. 4. To survey the differences of evaluation between parents and teachers on achievements of readiness. Ⅱ. Method 1. subjects were 848 mothers of primary school first graders and 20 primary school teachers.

This paper presents the program to analyze an antenna for using the Moment Method. The program contains three different functional steps. In the first stage, the pre-processor is based on the Delaunay Triangulation Algorithm. The next stage, the main-processor, can be considered the core process of the program, which solutions are obtaining the linear matrix for using the Moment Method. The final stages, the name of the post-processor, analyze radiation patterns, which results are same with the S-parameters. The results demonstrate satisfactory agreement with the results for using other numerical packages and measurement data. We can confirm that the results of this program compare with the results of common program to analyze for an antenna.
