Thermally-induced errors originating from machine tool errors have received significant attention recently because high speed and precise machining is now the principal trend in manufacturing proce sses using CNC machine tools. Since the thermal error model is generally a function of temperature, the thermal error compensation system contains temperature sensors with the same number of temperature variables. The minimization of the number of variables in the thermal error model can affect the economical efficiency and the possibility of unexpected sensor fault in a error compensation system. This paper presents a thermal error model with minimum number of variables using a fuzzy logic strategy. The proposed method using a fuzzy logic strategy does not require any information about the characteristics of the plant contrary to numerical analysis techniques, but the developed thermal error model guarantees good prediction performance. The proposed modeling method can also be applied to any type of CNC machine tool if a combination of the possible input variables is determined because the error model parameters are only calculated mathematically-based on the number of temperature variables.

This paper analyses the harmonic pollution to power grids caused by several high-power rectifiers, summarizes the requirements for rectifiers in suppressing grid-side current harmonics and optimizes a new-type of current source PWM rectifier with a hybrid switch. The rectifier with a hybrid switch boasts significant current characteristics and cost advantages in the high-power area. To further enhance the working frequency of the current source rectifier with a hybrid switch for suppressing grid-side harmonics and reducing the inductance size, this paper proposes an optimal control strategy based on space vector. It also verifies that the optimal control strategy based on space vector can reduce the total harmonic distortion of the grid-side current of the rectifier with a hybrid switch via circuit simulation and experimental results.

The effective exploitation of resources is critical for startup firms with insufficient resources to compete with well-resourced large firms. The direction and consistency of the resource input should be retained to utilize resources effectively, which will lead to a necessity for a fit between the strength in resources and the strategy of a firm. This study suggests hypotheses and verifies them empirically based on the logic that the attribute of resources in which a firm with a core competence decides the type of strategy and the formulated strategy presents the direction of the resource input, which enables the effective utilization of resources and facilitates high performance. According to the statistical results, the R&D capability affects the innovative differentiation strategy, marketing capability affects marketing differentiation strategy, and financial and production capability affects low cost strategy, in which the efficacy of the strategy depends on the attribute of resources. In addition, the R&D capability and marketing capability adversely affect the low cost strategy and the production capability negatively affects the innovative differentiation strategy, which implies that the exclusive choice of a strategy by the strength in resources results in improved performance. These results show that the fit between the resource and strategy is an essential cause of high performance in venture businesses.

How the society perceives National Park plays the most important role to achieve the goal for the National Park, which is to protect the ecosystems in the park. The survey for the visitors to Soraksan National Park was conducted to search for the answer to the question. As a result of the analysis based upon the perception types derived from the survey and factors affecting those types, the National Park can be explained by emotionally oriented type(scenic beauty), culturally oriented type, recreation oriented type, and economically oriented type. The first three types are strongly rooted in traditional culture, whereas the fourth type always conflicts with the goal of ecosystem protection. Korea has a long way to go to be familiarized with both the concept of ecosystem protection required by IUCN(The World Conservation Union) and the environmental ethics approach popularly promoted in the western world. The long term strategy for the protection of natural ecosystem should be approached in a manner that the traditional culture can be integrated into all aspects of park management.

A photograph, which was applied to contemporary art, plays a very important role in the whole of the multiplied and diversified contemporary arts today. The application of photos, which were shown in contemporary art following the 1950s, can be classified into five types according to role and function of a photo in the process of developing a work. However, this classification is shown a little ambiguously. That is because photos of being utilized by artists are indicated very diversely depending on their artistic strategy and situation. As the first type, a few painters utilize a photo as mirror of reality in order to materialize a challenging and revolutionary idea with going against traditional picture in their pictorial practice. As the second classification, especially American painters utilize a photo as material component of forming their picture like photo-montage or collage. The combined application of this medium is first doing genre de-construction and hybridization of post-modernism in the 1980s while ultimately aiming at social criticism or political satire. The third type implies particularly a case that avant-garde artists utilize a photo as evidence of a work. In this case, a photo is employed as evidence of a work, which disappears in the temporal space essentially like body art, land art, and performance. Also, as the fourth type is a case of utilizing a photo for artistic concept of a work, not pictorial practice of picture, it is utilized often as important artistic strategy of conceptual artists. The final type of utilizing photo is a case of applying photo as formative tool on behalf of dye-stuffs or crayon in order to record a section of reality, which always continues regardless of event or meaning any more, in the traditional picture. In this case, a work is indicated as a photo of having a form of picture, namely, as Forme-tableau. The main subject is indicated there as a daily case of being repeated always the extremely common and revived theme.

This study tried to verify the context effect in cosmetics advertisements by examining the cosmetics advertisement effect according to whether the brand image and the model image matched, and whether the brand image and the advertisement copy were harmoniously perceived. To this end, data were collected using the brand value type (3) × advertisement copy type (3) factorial design. The results are as follows. First, as a result of confirming the advertising effect according to the matching of the cosmetic brand image and the model image, it was found that both the advertising attitude and purchase intention were significantly high when the model image and the brand image matched. Second, it was confirmed whether there was a difference in the advertisement effect according to whether the cosmetic brand image and copy type matched. As a result, consumers who perceived that the cosmetic brand image and copy type matched had significantly higher advertising attitudes and purchase intentions than consumers who perceived that the copy type did not match. It is expected that it will provide validity as to whether the copy strategy should be established by incorporating the context effect when setting up a copy strategy for cosmetics advertisements in the future.

In order to provide theoretical guidance to research in platform strategy, we build the conceptual framework based on the organizational ecology and analyze symbiotic/competitive relationship between platform entities. Platform owner and service provider (i.e. complementors) make symbiotic relationship, where platform owner provide service provider user-base and platform resources such as marketing tools and platform technology, and service provider provide platform owner services which users utilize. In addition to symbiotic relationships, platform owner has competitive relationship with other platform owners, and service provider builds competitive relationship with other service providers. In these relationships, the strategy of platform owner affects service provider and service provider builds a strategy for their own survival and success. This type of interaction makes competitive dynamics in platform. However, previous platform literature focuses on strategies to enhance network effect from the perspective of platform owner. Thus, there is little attention on interaction among the service providers. Using the framework based on community ecology of organizational ecology, we analyze interaction and strategy between platform owner and service provider in the viewpoint of platform openness strategy and platform pricing strategy. This research contributes to the literature of platform strategy by providing a theoretical framework based on organizational ecology to deeply understand the dynamics of platform.

This study employs a novel beam-type wavelet finite element model (WFEM) to fulfill an adaptive-scale damage detection strategy in which structural modeling scales are not only spatially varying but also dynamically changed according to actual needs. Dynamical equations of beam structures are derived in the context of WFEM by using the second-generation cubic Hermite multiwavelets as interpolation functions. Based on the concept of modal strain energy, damage in beam structures can be detected in a progressive manner: the suspected region is first identified using a low-scale structural model and the more accurate location and severity of the damage can be estimated using a multi-scale model with local refinement in the suspected region. Although this strategy can be implemented using traditional finite element methods, the multi-scale and localization properties of the WFEM considerably facilitate the adaptive change of modeling scales in a multi-stage process. The numerical examples in this study clearly demonstrate that the proposed damage detection strategy can progressively and efficiently locate and quantify damage with minimal computation effort and a limited number of sensors.
