The Relationships among Lean Production, Operational Performance, and Financial Performance
The objective of this study is to investigate the relationships among lean production, operational performance, and firm performance; thereby, the study was conducted and accomplished by means of quantitative method using random sampling and snowball sampling. The results were analyzed by descriptive statistics, confirmatory factor analysis, and the structural equation modeling by using statistical software programs. Considering the quantitative approach, a survey was conducted with 629 current middle and top managers working in Thai manufacturing industry. The majority of respondents were male (56.3%) of the age above 40 years old (32.6%), factory/production manager (39.1%), bachelor’s degree (75.8%), working in medium size company (36.9%), nonautomotive (60.9%), and company age above 15 years (46.6%). The findings reported that there were positive relationships between lean production and operational performance, lean production and financial performance, and operational performance and financial performance. In addition, the results presented that there was partial effect of lean production on financial performance through operational performance. Considering the structural model level, the results further revealed that the model was not different across the automotive and nonautomotive industry, and the model was not different across the lean production adoption less than 5 years and above 5 years. Regarding the path level, the results reported that all of each path model level was not different across automotive and nonautomotive industry. Similarly, the lean production adoption, whether less than 5 years or above 5 years, did not have any effect on all of the path model levels.
The Impact of Environmental Regulation and Threats of Regulation on Environmental Performance for Canadian Firms: Expectations Versus Reality
Camélia Radu, Claude Francoeur
Environmental regulation in Canada suffers major changes, voluntary approaches are replaced with mandatory standards and regulations. Canada has a mixed regulatory system: federal environmental regulation combine or overlap with provincial regulation to encourage environmental innovative solution and pollution abatement. Following Canadian international commitments for sustainable development and fight against climate change, new guidelines, permits, agreements, authorizations, codes of practice, taxes and regulations are issued to insure a sustainable development of Canadian economy. These changes are deemed to reduce pollution and to enhance environmental performance of Canadian firms. This research investigates the evolution of environmental performance of Canadian firms and the impact of environmental regulation and threats of regulation on environmental innovation and environmental performance and provide insight on the gap between expectations of this impact and reality. We find empirical evidence of a positive impact of changes in regulation and threat of regulation on the environmental innovation at industry level. Environmental performance register important fluctuations and is negatively associated with environmental regulation, the positive changes in environmental innovation are not yet translated in better environmental performance. At country level, both environmental innovation and environmental performance follow the variation of environmental

Floor Radiant Heating System with PCM
Jin Chul Park, Sang Hoon Baek
This study deals with the application of PCM to the floor heating system. The results of this study are summarized as follows: (1) The existing, in Korea, floor heating system has the problem that a large amount of hot water and energy are consumed because of the low thermal storage performance of light weight aerated concrete and mortar. To solve this problem, we proposed a design of the floor heating system with PCM by applying PCM as a thermal storage material. That is, the floor heating system with PCM is constructed by applying floor construction materials in the order of the 210 mm concrete slab, 20 mm buffer material, 15 mm mortar, 10 mm PCM aluminum case, 55 mm mortar, and the floor finish. (2) The applicable melting point of PCM for the floor heating was calculated using the heat transfer model equation proposed in this study, and when the 5 mm wood floor finish was applied, the melting points of PCM products available were calculated to range from 32 ℃ to 39 ℃.
An Interactive Real-Time Shadow Play System Using Kinect
This paper presents an interactive real-time shadow play system. We propose a novel digital and interactive real-time shadow play system using Microsoft Kinect. Users can operate the shadow characters by employing their body movement without any professional training. A performer’s skeleton data captured from Kinect is mapped into the shadow puppet’s component automatically. Additionally, users can create own digital shadow play animations. our system not only accomplishes human-computer interaction, but also promotes the digital archives of the intangible cultural heritage.

Reconstruction of Social Science and Humanities through Narrative
Kang, Hyeon-Suk, Shin, Hye-Won
The purpose of this paper is to present new directions and research strategies through critical analysis of the academic tendencies of existing social science and humanities. The narrative theory of human experience is adopted as a theoretical rationale for critical analyzing existing social sciences and humanities. Since the 1970s and 1980s, the academic tendencies of the humanities and social sciences have been transformed into narrative turn. However, the academic tendency of the humanities and social sciences is still divided into several subdisciplines, and as a result, there are problems of approaching the discipline from the individual and separate stance that cannot be integrated. These problems are linked to limitations in explaining the totality of human life in an integrated way, and academic researchers also have a tendency to separately approach disciplinary research activities. In order to improve these existing separated and divided attributes, we focus on the new integrity of humanities and social sciences in light of the narrative theory that approaches the totality of human life. The narrative theory for academic inquiry makes use of the position of Bruner, Polkinghorne, Ricoeur. To do this, we reviewed the literature related to the research topic and took an integrated approach to philosophical analysis of core claims. As a result, narrative theory has a characteristic approach to human life and experience as a whole, and it is possible to integrate by narrative ways of knowing. Based on this narrative theory, existing humanities and social sciences need to be reconstructed into narrative science. And narrative method or narrative inquiry is useful as its specific inquiry method. As a narrative science, humanities and social sciences can be implemented by the integration of human experience and narrative epistemology. It has the advantage of integrating the atomized sub-sciences into the narrative of human experience according to this new method. Also, in-depth research on concrete exploration strategies is expected in the future.
Bruner‟s Educational Theory and Its Implication: Focusing on New Humanities
Kang, Hyeon-Suk1*, Lee, Ji-Eun
The purpose of this study is to analyze pre-existing humanities‟ tendencies and to suggest the new viewpoint based on Bruner‟s educational theory. As many subordinating disciplines are divided under humanities, humanities have a separate approach. This problem showed many limits to represent the humans‟ lives in an integrated way. Furthermore, researchers in the humanities field approached them in separate way. To renovate the pre-existing separate traits, this study focuses new totality of humanities based on Bruner‟s educational ideals. For this, the methodology of this study is to review the literatures and analyze them in philosophical ways. The existing humanities pursued objectivity and tried to theorize into one theory or formula. As a result, it ignored the essence of humanities and lost its identity by mimicking the popular natural science in the era. For resolving the phenomenon, Bruner‟s educational ideals have been showed by suggesting a narrative view of approaching humans‟ lives and experiences in an integrated way. According to him, humanities now have to return to the discipline based on coexistence, breaking down boundaries and accepting various possibilities and diversity. Regarding his viewpoint, pre-existing humanities should be re-conceptualized into narrative science or narratology. Humanities as a narrative science have advantages for integrating diverted subordinating disciplines into human experience‟s narrative and for paying attention to the totality. Since this study is based on Bruner‟s literature, future research on the direction of humanities will need to be further developed and generalized through various literatures and practice.
