  • This study aims to grasp the vital rhythm of the Chapel at Ronchamp by analyzing its rhythm through Henri Lefebvre's 'rhythmanalysis' in an effort to show the possibility of approaching the presence of this chapel. For the purpose of this study, Lefebvre's thought of rhythmanalysis was first contemplated, and a case study analysis was conducted on the concept and presence of the chapel in the design process. On this basis, examples of the chapel's rhythms were analyzed through Lefebvre's dialectical analysis of the triad of time(melody), space(harmony) and energy(rhythm). The results of analysis are as follows: First, the concept intended by Le Corbusier in the process of designing the Chapel at Ronchamp is expressed as the acoustic form, the modulor corresponding to the scale of the music, the light and shadow of counterpoint, and the opposite composition of musical changes. Consequently, the concept-mediated presence of this chapel is the presence of music. Second, at the Chapel at Ronchamp, a Lefebvre's rhythmanalyst experiences, or rather senses, two vital rhythms of an antithetical unity (i.e., acoustic curved rhythm and modulor-generated linear rhythm), with reference to his/her own rhythms. These rhythms are a dialectical union of spatiality of melodies temporalized through continuity, (i.e., acoustic curved form and modulor-generated linear form), and temporality of harmonies spatialized through simultaneity (i.e., light and shadow, materials and color, form of interpenetration, and stairs or windows/doors). These rhythms carry the measures generated by music-specific repetitions and differences in movements(energy). Consequently, the rhythm-mediated presence of this chapel is also the presence of music. In conclusion, the Chapel of Ronchamp indicates that an approach toward its presence can be realized through vital rhythms derived from Lefebvre's 'rhythmanalysis'. This study holds significance as an analysis of spatial rhythm and presence, employing a philosophical thought.

  • This study intends to make a proposal the direction classification to develop the independent study of e-book's visualization. For this, we research into the e-book of Disney animation which achieved recognition in the literary value and amusement First of all, We grasp the meaning of the concept of e-book's aerial-image and perceptual principle. Next, We found the subject that starts the movement, and then observed the factor of the presentation to be possible to experience the actual spatial experience by the motion-produced cues. Through analysis process, We can classify the appearance elements, media, camera, and the readers' motion-produced cues into 13 parts and define as the codes. As we analysis the frequency of use of the analysis object, We separated it into the 46 combination exercises. According to the combination with the independent exercise, We separated them into 4 groups. There are the actual spatial experience, narrative spatial experience, the experience of characters. The basis for these, we can analyze the characteristics of the motion-produced cues. This study has the meaning of the expansion of e-book into the film language system by separating the e-book's narrative visualization type.

  • Clean development mechanism (CDM) validity study was conducted to suggest better and more adaptable CDM scenario on water treatment plant (WTP). Potential four scenarios for CDM project; improvement of intake pumping efficiency, hydro power plant construction, solar panel construction and system optimization of mechanical mixing process were evaluated on S-WTP in Korea. Net present value (NPV) of each scenario was estimated based on sensitivity analysis with the variable factors to investigate the CDM validity percentile. Hydro power plant construction was the best option for CDM business with 97.76% validity and $1,127,069 mean profit by 9,813 $tonsCO_2e$/yr reduction. CDM validity on improvement of intake pumping efficiency was 90.2% with $124,305 mean profit by huge amount of $CO_2$ mitigation (10,347 $tonsCO_2e$/yr). System optimization of mechanical mixing process reduced 15% of energy consumption (3,184 $tonsCO_2e$/yr) and its CDM validity and mean profit was 77.25% and $23,942, respectively. Solar panel construction could make the effect of 14,094 $tonsCO_2$ mitigation annually and its CDM validity and mean profit was 64.68% and $228,487, respectively.

  • This study aims to analyze the factors that influence people's behavioral intentions to recycle waste and focus on people's perceptions of informal waste recycling. The low level of participation in the e-waste recycling process makes research on the factors that encourage household interactions in sorting waste or recycling waste a priority. The purpose of this study is to build a comprehensive model and examine the relationship between perceptions of informal recycling, implementation e-waste management, behavioral intention, convenience of recycling and perceived behavioral control. The framework is the Theory of Planned Behavior (TPB). The implementation variable e-waste management is used to mediate the relationship between the two constructs. Respondents in this study were cellular phone users who had changed their phones. The number of respondents in this study totaled 165, using the purposive sampling technique. Data analysis techniques in this study used PLS-SEM with WarpPLS version 6.0. The findings show that: (1) perception of informal recycling, e-waste management, and behavioral intention have a significant positive effect; (2) management of e-waste, perception behavioral control and behavioral intention have a positive effect; and (3) the implementation of e-waste management, which causes the convenience of recycling, will increase the intensity of behavior, indicating the results are rejected.

  • The major concern of e-learning environment design is to create and improve artifacts that support human learning. To facilitate effective and efficient learning, e-learning environment designers focused on the contemporary information technologies. Web 2.0 services, which empower users and allow the inter-transforming interactions between users and information technologies, have been increasingly changing the way that people learn. By adapting these Web 2.0 technologies in learning environment, educational technology can facilitate learners' abilities to personalize learning environment. The main purpose of this study is to conceptualize comprehensively constructs for understanding the inter-transforming relationships between learner and learning environment and mutable learning environments' impact on the process through which learners learn and strive to shape their learning environment. As results, this study confirms conceptualization of four constructs by incorporating aspects of design that occur in e-learning environments with Web 2.0 technologies. First, learner-designer refers to active and intentional designer who is tailoring an e-learning environment in the changing context of use. Second, learner's secondary design refers to learner's design based on the primary designs by design experts. Third, transactional interaction refers to learner's inter-changeable, inter-transformative, co-evolutionary interaction with technological environment. Fourth, trans-active learning environment refers to mutable learning environment enacted by users.

  • Bioinspired sea urchin-like structures were fabricated on silicon by inductively coupled plasma (ICP) etching using lens-like shape hexagonally patterned photoresist (PR) patterns and subsequent metal-assisted chemical etching (MaCE) [1]. The lens-like shape PR patterns with a diameter of 2 ${\mu}m$ were formed by conventional lithography method followed by thermal reflow process of PR patterns on a hotplate at $170^{\circ}C$ for 40 s. ICP etching process was carried out in an SF6 plasma ambient using an optimum etching conditions such as radio-frequency power of 50 W, ICP power of 25 W, SF6 flow rate of 30 sccm, process pressure of 10 mTorr, and etching time of 150 s in order to produce micron structure with tapered etch profile. 15 nm thick Ag film was evaporated on the samples using e-beam evaporator with a deposition rate of 0.05 nm/s. To form Ag nanoparticles (NPs), the samples were thermally treated (thermally dewetted) in a rapid thermal annealing system at $500^{\circ}C$ for 1 min in a nitrogen environment. The Ag thickness and thermal dewetting conditions were carefully chosen to obtain isolated Ag NPs. To fabricate needle-like nanostructures on both the micron structure (i.e., sea urchin-like structures) and flat surface of silicon, MaCE process, which is based on the strong catalytic activity of metal, was performed in a chemical etchant (HNO3: HF: H2O = 4: 1: 20) using Ag NPs at room temperature for 1 min. Finally, the residual Ag NPs were removed by immersion in a HNO3 solution. The fabricated structures after each process steps are shown in figure 1. It is well-known that the hierarchical micro- and nanostructures have efficient light harvesting properties [2-3]. Therefore, this fabrication technique for production of sea urchin-like structures is applicable to improve the performance of light harvesting devices.

  • It is now widely recognized that new Information and Communication Technologies (ICTs) have been changing the way tv which firms conduct their businesses. Examples are the application of enterprise resources planning (ERP) and business process reengineering (BPR) to increase the efficiency of internal resources management, adoption of Business-to-Business e-commerce (B2B e-com) to integrate supply chain, and invention of new marketing channels such as Business-to-Customer (B2C) e-com. These new ways of conducting businesses are believed to help firms to reduce transaction costs and increase productivity. As a result, new ICTs have played an important role in recent growth of many small firms into multi-functional and multi-product corporations and in their spatial expansion towards internationalization as well. This paper takes Haier in China as a case to study the role of new ICTs in the growth of firms and reveal how the new technologies have facilitated the expansion of Haier into a transnational corporation (TNC) by examining the internationalization process of the firm in relation to its adoption of new ICTs in the period from 1990 to 2002. The study reveals that the adoption of new Ins has helped Haier to integrate its functional units located in dozens of places across the world, which is essential to the internationalization of a firm, and to link closely together its worldwide suppliers and customers to achieve just-in-time (JIT) production and delivery. As such, the authors of the paper argue that, without the facilitation of new ICTS, Haier could not have developed into a TNC in less than ten years.It is now widely recognized that new Information and Communication Technologies (ICTs) have been changing the way tv which firms conduct their businesses.
