In recent years, the automobile industry has been facing a major change with the introduction of new technologies represented by autonomous driving, electrification, and digitalization. Major domestic and overseas automakers are trying to use a systematic approach to customer satisfaction through user interfaces to provide customers with a special experience and value beyond just making products with high performance. This study proposes the Kano model as a systematic and qualitative research method for satisfaction. As a case study, 17 functions of a product were sorted (3 operation functions, 7 safety functions, and 7 convenience functions). This was done by analyzing the use case and the customers' requirements for a smart trunk system. 18 new functions were derived via creative ideation codes. In addition, a scientific analysis method is proposed for product quality attributes and the strength of customer satisfaction. Using the Kano methodology, 25 functions were classified into quality attributes: 18 attractive qualities, 3 one-dimensional qualities, and 4 complex qualities, which are combinations of one-dimension qualities and must-have qualities. The functions that have one-dimensional quality and complex qualities were found to have higher customer ratings than the functions that have attractive qualities. Based on this, enterprises could effectively reduce customer complaints and enhance customer satisfaction.

An on-going creative process was the major principle of Kantor's artistic endeavors. Kantor's emphasis on process grew out of his frustration with the experience of creation being isolated from the audience in the present time, during the moments of encounter. At the same time, however, Kantor was always aware of the fact that the first night of each and every performance that he made was the last point of his creative intervention. Despite being performed live in the present time, Kantor saw theatre essentially as an end product. This does not mean that Kantor abandoned the concept of on-going process, for process was for the artist a means to reject the idea of a finished work of art and to denounce the feeling of satisfaction derived from the traditional denouement in representational theatre. For him, theatre that dominated his time isolated the audience from the art work and the artist, and from this perspective his continual emphasis on process should be understood as an aesthetic principle in order to open up and expand the dimension of art into the realm of the spectator so that the experiences of both the artist and spectator may coexist. The heaviest barrier that separated the artist and his work from its audience was the creative structure that governed Western art. In theatre it was the dramatic structure that was the main object of his series of severe challenges. Not only did it fail to represent reality but it distorted reality, creating nothing but artificial illusion. Under this condition, all that was permitted to the audience was mirages. However, Kantor never completely discarded illusion from his theatre. The point for him was always to created a circumstance where the illusory reality of drama comes to exist within the dimensions of our reality. It was Kantor's belief that instead of a total denial of illusion, his theatre should strategically accommodate illusion which comes from reality. And, the aim of Kantor's theatrical experiments was to invite the audience into this ambience and transform the experience of his audience into a much more participatory one. This paper traces the ways in which Kantor transgressed the dominating conventions of representational, literary theatre, and how such attempts induced an alternative mode of spectatorship. The study will begin from an investigation into Kantor's attitude towards illusion and reality, and then move onto a closer inspection of how he spatially and dramaturgically materialized his concepts on stage, giving special focus on Wielopole, Wielopole.

The mainstream of cinema animated film in today's world is the animated film produced by film companies such as Disney, DreamWorks, and 20th Century Fox. These animated films are influenced by Hollywood blockbusters, high cost, and big-budget, which have brought a gorgeous and splendid audio-visual feast to the global audience. DreamWorks Studios founded in 1994 has become noted in just over ten years. It has produced many high-quality animated works which are well-known all over the world. This achievement is no doubt inseparable from its superior external animation industry environment, and benefited from the American animation industry which commercially operated for almost 100 years. However, in addition to these external environmental factors, DreamWorks' achievements have also come from the extraordinary and superior creation of the animated film scripts, strong narrative script ensures the logic and appeal of animated films. This article takes Kung Fu Panda series, Shrek series, The Prince of Egypt, The Croods, Chicken Run, Megamind and other representative films produced by DreamWorks as key analysis object, using Jean Baudrillard's simulation and imaging theory, Syd Field's screenwriting skills, and Hegel's aesthetic point of view, explores the Creative Style of DreamWorks' Animated Film Script which contains the following four aspects. The script is exaggerated and novel, and the subject matter is rich and targeted. The script creation is very imaginative and can fully express the visual beauty. The structure of the story is well controlled, the space comes from reality but full of imagination. The characters have distinctive personality and the dialogue is moderated but forceful.

In this paper, we propose and assess the performance of "H infinity filter ($H_{\infty}$, HIF)" and "cost reference particle filter (CRPF)" in the problem of tracking a target based on the measurements of the range and the bearing of the target. HIF and CRPF have the common advantageous feature that we do not need to know the noise statistics of the problem in their applications. The performance of the extended Kalman filter (EKF) is also compared with that of the proposed filters, but the noise information is perfectly known for the applications of the EKF. Simulation results show that CRPF outperforms HIF, and is more robust because the tracking of HIF diverges sometimes, particularly when the target track is highly nonlinear. Interestingly, when the tracking of HIF diverges, the tracking of the EKF also tends to deviate significantly from the true track for the same target track. Therefore, CRPF is very effective and appropriate approach to the problems of highly nonlinear model, especially when the noise statistics are unknown. Nonetheless, HIF also can be applied to the problem of timevarying state estimation as the EKF, particularly for the case when the noise statistcs are unknown. This paper provides a good example of how to apply CRPF and HIF to the estimation of dynamically varying and nonlinearly modeled states with unknown noise statistics.

In this paper, a finite impulse response(FIR) fixed-lag smoother is proposed for discrete-time nonlinear systems. If the actual state trajectory is sufficiently close to the nominal state trajectory, the nonlinear system model can be divided into two parts: The error-state model and the nominal model. The error state can be estimated by adapting the optimal time-varying FIR smoother to the error-state model, and the nominal state can be obtained directly from the nominal trajectory model. Moreover, in order to obtain more robust estimates, the linearization errors are considered as a linear function of the estimation errors. Since the proposed estimator has an FIR structure, the proposed smoother can be expected to have better estimation performance than the IIR-structured estimators in terms of robustness and fast convergence. Additionally the proposed method can give a more general solution than the optimal FIR filtering approach, since the optimal FIR smoother is reduced to the optimal FIR filter by setting the fixed-lag size as zero. To illustrate the performance of the proposed method, simulation results are presented by comparing the method with an optimal FIR filtering approach and linearized Kalman filter.

This study attempted to verify the influence of strong and weak ties on the performance of project based organizations by examining various tie relationships in the Korean TV drama making industry. The extant literature has suggested that the impact of network ties depends not only on their strength but also the network contexts (i.e., project characteristics). Due to artistic and creative nature of TV drama making, it is hypothesized that weak tie networks among critical human resources would outperform strong tie networks. Empirical results support the hypothesis that weak tie networks indeed outperform strong tie networks in terms of viewing rate of drama.

In this paper, experiments with an air-breathing proton exchange membrane fuel cell (PEMFC) for mobile devices were carried out according to cathode conditions. These conditions are defined by the cathode flow field plate type (the channel type, the open type) and the cathode surface direction. Single-cell and 6-cell stack were used in the experiments. The experimental results showed that the open-type cathode flow field plate gave a better performance than the small channel type. In the experiments related to the direction of the slits on the cathode flow field plate, the horizontal slit cell was better than the vertical one. With respect to the cathode surface direction, when the cathode surface is placed in the direction normal to the ground, the PEMFC generated more stable power in the mass transport loss region. Since stable power in the mass transport region is closely related to the air supply, computational fluid dynamics (CFD) analysis for air-breathing PEMFC of different cathode surface directions was performed.

National Competency Standards are the major administrative project to build a competence-based society. The manpower for the global society should be recognized by performance rather than educational records. Therefore, all colleges should first nurture NCS-type manpower based on field needs. This study comparatively analyzed the differences between the lecture style of four-year colleges and the outcomes of problem-solving and project-based learning method to prove why it is necessary to introduce the NCS program. Especially, It will review the constraints and measures of NCS introduction to overcome in a four-year university. Through this, it can be used as a means to help improve the field conformity of a four-year college curriculum by presenting the development and utilization of curriculum-based NCS in a four-year university. As a result, it was found that the overall satisfaction with the problem-solving and project-based learning method was above average. Many students were dissatisfied with the traditional teaching methods and the new project-based learning method was relatively effective in college education. Students' participation also improved. Based on the evaluation of learning performance, the new method was found more satisfactory than the old teaching method in terms of comprehension of professional knowledge in various fields, nurturing of logical thinking skills, acquisition of analytical skills, comprehensive thinking skills, creative problem recognition, and open-minded thinking skills.

Improvement in the control strategy for continuous casting is a crucial requirement to enhance the slab's quality and to increase productivity. The mold oscillator adopts the dual cylinders due to its heavy weight, so the synchronized motion of two cylinders is an important aspect when precise control is needed. The conventional method uses the master-slave control applied to the valve input reference, but the synchronization performance should still be improved. This paper proposes a novel synchronization algorithm for dual cylinders used in a mold oscillator. The master-slave concept is applied to the target reference position, that is, the slave target reference position is controlled to match the slave cylinder's position with the master cylinder's position. In the simulation based on a Simulink model, the proposed algorithm shows a better synchronization performance in aspect of the mean of the absolute error and the peak synchronization error.
