Today, 'Emotion' has come to stay as a powerful culture code. Though there has been not a few research results based on the recognition of the importance of emotion, the concept of 'Emotion' still differs according not only to researchers but also to the fields. There firstly lies the aim of this study to research the moaning and feature of 'Emotion' through John Dewey's Theory of Experience. Secondly, this study tries to categorize the strata of emotion in space, and further tries to present the methodology for the study of emotion shown in the space. Emotion is the impulse corresponding to the root force drawing out indefinite situations into the context of the problem, and is also the force which integrates all the elements in the process of reflective correlation. Emotion can be referred to as the activating and combining force which makes it possible for the separate elements to be related to the whole as one, and as the feature forming the completion of the transaction between organisms and environment.

We introduce and analyze a frequency-domain method for parabolic partial differential equations. The method is naturally parallelizable. After taking the Fourier transformation of given equations in the space-time domain into the space-frequency domain, we propose to solve an indefinite, complex elliptic problem for each frequency. Fourier inversion will then recover the solution in the space-time domain. Existence and uniqueness as well as error estimates are given. Fourier invertibility is also examined. Numerical experiments are presented.

In this paper, we propose a centralized $H^{\infty}$ state estimator for the multi state estimation problem using the result suboptimal $H^{\infty}$ filter is a special form of Ka filter whose state equations are defined in md inner product spaces. Con- ventional decentr filters are based on Kalman filter assumes precesses and measurements noises are w Gaussian noise. Therefore, Kalman based decent filter design hasn't robust performance in situation. Simulation results show that decent $H^{\infty}$ filter has robust perfotmance in worst case sensor fault situation.

The increase of female employees tends to change the traditional division of the roles of members in the family, and as a result it changes the idea of family relation and the extent of how housewives with job feel happy toward their marriage. Therefore, it may be very significant to study what attitude woman job holders as housewives have toward their family, especially parents-in-law. In this paper the writer has sampled as an exemplary group woman teachers who teach home economics in high schools in Seoul, and investigated what opinion they have toward the problem of living together under the same roof with their parents-in-laws and otherwise of financing them in an older age. This analysis is based upon 130 questionnaires collected as proper data out of 138. The conclusion made from the analysis is as follows : (1) as regards the living together under the same roof if necessary in the future, one-fifth of the group approves in affirmative terms ; (2) but when parents-in-law become older, about half of the teachers wish to live with them in the same home and except the indefinite few, one-third of them taken the negative position ; (3) finally, the great majority (84%) regard as their duty the financial support in any case when parents-in-law become older, and only five per cent answer in negative. This analysis leads to the further conclusion that the idea of family relations cherished by high school teachers of home economics is not yet far off the traditional relationship with the intention of gradual improvement, but on the other it still sticks to the traditional line without too much impairing it.

In this paper, we study ${\alpha}$-completely positive maps between locally $C^*$-algebras. As a generalization of a completely positive map, an ${\alpha}$-completely positive map produces a Krein space with indefinite metric, which is useful for the study of massless or gauge fields. We construct a KSGNS type representation associated to an ${\alpha}$-completely positive map of a locally $C^*$-algebra on a Krein locally $C^*$-module. Using this construction, we establish the Radon-Nikod$\acute{y}$m type theorem for ${\alpha}$-completely positive maps on locally $C^*$-algebras. As an application, we study an extremal problem in the partially ordered cone of ${\alpha}$-completely positive maps on a locally $C^*$-algebra.

Nowadays, circulation industry is taking charge of important role in improvement of competitive power on the manufacturing industry and public welfare increase of consumer, price stabilization, employment creation and so on. A lot of research have been progressing for formation of total circulation complex, but decision making for selection of location on some facility is only calculated the optimum value when correct data values are inserted. However, a lot of decision making is accomplished in situation that have little knowledge of objective and constraints and as real world is also evaluated inclusive of analyst's subjectivity about variable, indefinite and fuzzy part, so it is decreasing a reliability on evaluation result and complicating objective evaluation on various effect and negative impact. Accordingly, from under like this situation, this study is to develop location decision model of circulation complex using fuzzy theory from the intention for the most reasonable decision making in fuzzy situation based on decision making problem on conventional location and size decision that did to be satisfactory constraints necessarily.

In navigation, officers receive data about inside and outside of ship from several devices(ex, GPS / AIS / ECDIS / ARPA Radar / etc) in bridge, and use it to recognize and predict safety situations. However, observation work of a officer is still hard for a torrent of data from several devices, and the problem of inconsistent data among the devices. In previous research, we presented the conceptual model of Intelligent Navigation Safety Information System based on information fusion, and showed the example of the conceptual model using CF (Certainty Factor) expert system to solve this problem. The information fusion technology needs various reasoning skills, and CF expert system is not enough to express ambiguous or indefinite factors. In this paper, we propose the concept of an intelligent navigation information fusion using fuzzy expert system to describe the ambiguous factors, and show the validity of applying fuzzy expert system to the Navigation Safety Information System through the design and implementation of the proposed concept.

Purpose - Six months have passed since the amendment of the SSM regulation law; however, as yet, there is no confirmed research or report on the effects of this amendment, which are indefinite. Further, there have been no attempts to study the effects of the SSM regulation law from the consumers' viewpoint, which is important because consumers are the main agents that are greatly influenced by the amendment law. Therefore, this study aims to investigate the consumers' attitude toward the SSM regulation law as well as the effects of the SSM regulation law on the changes in purchase behavior. Research design, data, and methodology - This study was initiated from four research problems that are linked to consumer reaction to the SSM regulation law. Research problem 1: What is the consumers' reaction (perception, attitude, and perceived fairness) to the SSM regulation law? Research problem 2: How do the consumers' reactions to the SSM regulation law differ by consumers' characteristics? Research problem 3: Could the SSM regulation law change a consumer's purchase behavior? Research problem 4: Is it necessary to amend the SSM regulation law? This study collected the data through the interview and survey of housewives for the purpose of solving the research problems. The interview was conducted as a pilot study for the field survey. We interviewed three housewives, who were: an employed housewife, a full-time homemaker, and a manager of a housewife club, respectively. We then conducted a field survey of 232 housewives who were housewife club members or elementary school parents in Chunghcheong-do. Results - We verified the reliability and validity of the data, and analyzed it to solve the research problems. The main findings of this study were as follows. First, consumers still have a positive attitude toward large discount chains and SSM, which has been the case since the law was introduced. Second, perceived risk of consumers associated with traditional markets and small neighborhood shops was low. Third, consumers think that amendments of the SSM regulation law are important, and they positively assess the satisfaction, necessity, and propriety of the law. Fourth, although the SSM regulation law caused inconvenience to consumers, this law did not have any influence on the usage frequency and the use-behavior of large discount chains. Finally, consumers reacted very negatively to the toughening up of the SSM regulation law. Conclusions - In short, consumers still have a positive attitude toward the SSM regulation law. However, this act did not have any influence on the use-behavior of large discount chains (General Super Market). Thus, policy making authorities require active communication and promotions to enhance the effect of the SSM regulation law. This study was of the nature of exploratory research, which did not focus on hypothesis testing, but on finding solutions to the research problems. Therefore, this study is no more than a simple data analysis. Future studies should attempt to investigate the actual effects of the SSM regulation law, on the basis of sufficient literature review and real sales data.

We can classify the scratches after CMP process into micro-scratch and macro-scratches according to the scratch size, scratch intensity and defect map, etc. The micro-scratches on wafer after CMP process are discussed in this paper. From many causes, major factor that influences the formation of micro-scratch is known as particle size distribution of slurry.(1) It is indefinite what size or type of particle can cause micro-scratch on wafer surface, but there is possibility caused by large particle over 1um. The best way for controlling these large particle to inflow is to use the slurry filter on POU(Point of user). But the slurry filter(especially, depth-type filter) has sometimes the problem which makes more sever micro-scratches on wafer surface after CMP. We studied that depth-type slurry filter has what kind of week-points and the number of scratch could be reduced by lowering slurry flow rate and by using high spray bar which sprays DIW on polishing pad with high pressure.

The new MPEG-4 video coding standard enables content-based functionalities. Image segmentation is an indispensable process for it. This paper addresses an effective segmentation of non-rigid objects. Non-rigid objects are deformable objects with fuzzy, blurred and indefinite boundaries. So it is difficult to segment deformable objects precisely. In order to solve this problem, we propose an effective segmentation of non-rigid objects using watershed algorithms in still pictures. And we propose an automatic segmentation through intra-frame and inter-frame segmentation process in video sequences. Automatic segmentation preforms boundary-based and region-based segmentation to extract precise object boundaries.
