  • Most recently, CP(Cellular Phone) has been one of the most important technologies in the IT(Information Tech-nology) field, and it is situated in a position of great importance industrially and economically. To produce the best CP in the world, a new technological concept and its advanced implementation technique is required, due to the extreme level of competition in the world market. The RT(Robot Technology) has been developed as the next generation of a future technology. Current robots require advanced technology, such as soft computing, human-friendly interface, interaction technique, speech recognition, object recognition etc. unlike the industrial robots of the past. Therefore, this paper explains conceptual research for development of the RCP(Robotic Cellular Phone), a new technological concept, in which a synergy effect is generated by the merging of IT & RT. RCP infra consists of $RCP^{Mobility}$ $RCP^{Interaction}$, $RCP^{Integration}$ technologies. For $RCP^{Mobility}$, human-friendly motion automation and personal service with walking and arming ability are developed. $RCP^{Interaction}$ ability is achieved by modeling an emotion-generating engine and $RCP^{Integration}$ that recognizes environmental and self conditions is developed. By joining intelligent algorithms and CP communication network with the three base modules, a RCP system is constructed. Especially, the RCP mobility system is focused in this paper. $RCP^{Mobility}$ is to apply a mobility technology, which is popular robot technology, to CP and combine human-friendly motion and navigation function to CP. It develops a new technological application system of auto-charging and real-world entertainment function etc. This technology can make a CP companion pet robot. It is an automation of human-friendly motions such as opening and closing of CPs, rotation of antenna, manipulation and wheel-walking. It's target is the implementation of wheel and manipulator functions that can give service to humans with human-friendly motion. So, this paper presents the definition, the basic theory and experiment results of the RCP mobility system. We confirm a good performance of the RCP mobility system through the experiment results.

  • Various methodologies have been proposed in discussions of sustainability to meet the needs and sustenance of both civilization and the ecosystem. Among them, the modern concept of biomimicry is emerging as a way to meet both the concepts of sustainable 'development' and 'society', due to its philosophical position encompassing the human-centered world view and the non-human-centered view of ecocentrism. Therefore, in the field of design in which it is necessary to take responsibility for environmental and social problems, this could be a good way to solve these issues. Biomimicry design can generally be divided into three stages: form, function, and ecosystem. From the point of view of ecological sustainability, ecosystem imitation is the most advanced and appropriate design approach that can solve the problems or even prevent them. Accordingly, this study derived a biomimicry design approach in the ecosystem imitation stage based on the concepts of biomimicry, ecological sustainability, and ecological aesthetics. The detailed approaches are 'imitation of the natural providence', 'imitation of the ecosystem's creation process', and 'imitation of the ecological cycle'. This study investigated and presented cases, such as the design imitating the ecological mechanism of microorganisms and the work using mark-making based on the derived design approach, because it could be too conceptual and idealistic by itself. Through this, we explored a method of applying and visualizing the concept of biomimicry in textile design at the ecosystem imitation level and showed its feasibility, although it still has difficulties in practical use.

  • The purpose of the study was to explore the conceptual and theoretical fundamentals of learning object. Learning object, a new paradigm for instructional design in the era of information technology, has attracted much research efforts since it has lots of advantages in terms of production efficiency and use effectiveness. A theory for the systematic design of this new instructional design, however, looks far from mature. Since the birth of the idea of a learning object has been found in the field of computer software design, such as object-oriented software development, learning object does not have enough theoretical underpinnings in terms of learning and instruction. The researcher tried to establish theoretical foundations for this new, alien concept as a learning design theory. Relevant research efforts and discourses have been discussed for this purpose.

  • Due to the growing interest in eco-friendly and sustainable design in the architectural and urban planning field, we are witnessing numerous projects in which old buildings are being reused. However, with the exception of domestic apartments, there hasn't been a systematic approach or policy regarding the reuse of specific building types. On the other hand, we were able to point out two public building types, dong-offices and primary schools, that are expected to be underused, with future needs for conversion. Because the two building types are public buildings, we believe that their conversion must address the needs of the society. In this study, we have chosen 'social integration' as the ultimate goal of reusing public buildings. Upon the conceptual model of 'Housing-Mixed Public Facility', which was produced in a previous study, we have added other core programs that could be adopted into the model. Then, we applied the improved model onto the two building types by producing conversion plans and introducing key planning techniques. During this process, we have found some regulations that would not allow the realization of some models. Therefore, we have suggested amendments to the related regulations.

  • Leadership is one of the most widely explored subjects in the field of management. A variety of papers on leadership, however, still have insufficient aspects to reveal the theoretical logic about the CEO leadership itself. Such research, especially focused on organizational performance, tend to concentrate on the CEO's behavior rather than leadership because CEO's behavioral trait as an explanatory variable is useful to connect with firms' performance. Our purpose is to show how the characteristic of CEO leadership can be built at the organizational level. For a detail, the larger the firms' size, the greater the degree of CEO's charismatic leadership. The larger the degree of a firm's diversification, the greater the degree of the CEO's transformational leadership. And the less the degree of a firm's diversification, the greater the degree of the CEO's transactional leadership. This theoretical paper on CEO leadership suggests that the characteristics of CEO should be adaptable to the changing institutions and organizational environments.

  • Understanding the process of carcinogenesis will involve both the accumulation of many scientific facts derived from molecular, biochemical, cellular, physiological, whole animal experiments and epidemiological studies, as well as from conceptual understanding as to how to order and integrate those facts. From decades of cancer research, a number of the "hallmarks of cancer" have been identified, as well as their attendant concepts, including oncogenes, tumor suppressor genes, cell cycle biochemistry, hypotheses of metastasis, angiogenesis, etc. While all these "hallmarks" are well known, two important concepts, with their associated scientific observations, have been generally ignored by many in the cancer research field. The objective of the short review is to highlight the concept of the role of human adult pluri-potent stem cells as "target cells" for the carcinogenic process and the concept of the role of gap junctional intercellular communication in the multi-stage, multi-mechanism process of carcinogenesis. With these two concepts, an attempt has been made to integrate the other well-known concepts, such as the multi-stage, multi-mechanisn or the "initiation/promotion/progression" hypothesis; the stem cell theory of carcinogenesis; the oncogene/tumor suppression theory and the mutation/epigenetic theories of carcinogenesis. This new "integrative" theory tries to explain the well-known "hallmarks" of cancers, including the observation that cancer cells lack either heterologous or homologous gap junctional intercellular communication whereas normal human adult stem cells do not have expressed or functional gap junctional intercellular communication. On the other hand, their normal differentiated, non-stem cell derivatives do express connexins and express gap junctional intercellular communication during their differentiation. Examination of the roles of chemical tumor promoters, oncogenes, connexin knock-out mice and roles of genetically-engineered tumor and normal cells with connexin and anti-sense connexin genes, respectively, seems to provide evidence which is consistent with the roles of both stem cells and gap junctional communication playing a major role in carcinogenesis. The integrative hypothesis provides new strategies for chemoprevention and chemotherapy which focuses on modulating connexin gene expression or gap junctional intercellular communication in the premalignant and malignant cells, respectively.

  • Background: Ecologists have achieved much progress in the study of mechanisms that maintain species coexistence and diversity. In this paper, we reviewed a wide range of past research related to these topics, focusing on five theoretical bodies: (1) coexistence by niche differentiation, (2) coexistence without niche differentiation, (3) coexistence along environmental stress gradients, (4) coexistence under non-equilibrium versus equilibrium conditions, and (5) modern perspectives. Results: From the review, we identified that there are few models that can be generally and confidently applicable to different ecological systems. This problem arises mainly because most theories have not been substantiated by enough empirical research based on field data to test various coexistence hypotheses at different spatial scales. We also found that little is still known about the mechanisms of species coexistence under harsh environmental conditions. This is because most previous models treat disturbance as a key factor shaping community structure, but they do not explicitly deal with stressful systems with non-lethal conditions. We evaluated the mainstream ideas of niche differentiation and stochasticity for the coexistence of plant species across salt marsh creeks in southwestern Denmark. The results showed that diversity indices, such as Shannon-Wiener diversity, richness, and evenness, decreased with increasing surface elevation and increased with increasing niche overlap and niche breadth. The two niche parameters linearly decreased with increasing elevation. These findings imply a substantial influence of an equalizing mechanism that reduces differences in relative fitness among species in the highly stressful environments of the marsh. We propose that species evenness increases under very harsh conditions if the associated stress is not lethal. Finally, we present a conceptual model of patterns related to the level of environmental stress and niche characteristics along a microhabitat gradient (i.e., surface elevation). Conclusions: The ecology of stressful systems with non-lethal conditions will be increasingly important as ongoing global-scale climate change extends the period of chronic stresses that are not necessarily fatal to inhabiting plants. We recommend that more ecologists continue this line of research.

  • This study concentrates on a new idea that is formulated as a creative spatialization in contemporary architecture and painting. It is stimulated from the classical baroque, which is expressed with the conceptual instruments, 'excessive', 'decorative', 'accidential' Suggested from that, this study tries to open the actual sense area of 'the baroque' by analysing the architectural ideas of wrenching and folding by Frank O. Gehry and in the same context by elucidating the dynamic deformalising of the figures by Francis Bacon. The redefined 'new baroque' operates in the chain of the transformable and flexible images that must be recognized as 'the real' in the sense of 'the most empirical' and are vulnerable to dispersal. The typical instrument of Gehry's 'new baroque architecture' is the enclosing of the space and its folding, and Bacon, whose painting can be called as the modern baroque, takes as the expressing methods a wrenching of the figures, a relieving of the colored background against the figure and a disappearing of figures into the background. These different ideas meet in the theoretical gravitation field of the philosophy of Deleuze, in which the reconstituted baroque conception means the tension between the folds, on expansion and contraction of which the variable space is dependent, Through the general principle of 'the new baroque', a free dispersal of power, to architect and painter is offered the possibility, not only to make the real world intimate to the real life, but also to produce from there a vivid new space. Finally it brings to enjoyer and viewer the possibility, to perceive the operating power in and around oneself.

  • This paper deals with visual confirmation device for tensile force verification in order to cope with tensile force loss of ground anchor. Ground anchors are constructed to ensure the stability of social infrastructure facilities, but continuous loss of tensile force is seriously concerned about safety of the facilities. This requires the maintenance of the anchors, but the current measuring of residual tensile force is done by sampling, taking into account economic aspects, which limits precision. In this paper, conducted a conceptual design, tensile experiment, and field test for the purpose of developing an anchor tensile force visual device to check the tensile force of the anchors.

  • The aspects of contemporary society change have been changed rapidly running for function value on the part of part industrialization and information-oriented. The transfer to the society focused on a human being emphasis and symbol value is in progress rising with natural desire of recurrence of human nature accordingly and desires of a human being inborn of sensitivity-oriented and pluralism-oriented are being expressed. Answering these social and cultural demands, concerns about an arbitrary mind world of a human being and pursuit dispositions about impractical and transcendental world are coincided with to the purpose and so various kinds of expressions except for art sphere are being experimented and applied. Here upon also in the field of the contemporary interior design, answering sensual desire of users, various arts and cultural tendency, the concept of surrealism is being applied in design introducing the concept of surrealism positive. And fantastical and unreasonable expression features of surrealism are being used as subjective essential elements to make new spaces. Especially amoung various kinds of the interiors designs, the features like surrealistic expressions in Food & Beverage Space which proper identity and strong symbolism will be expressed can be recognized as appropriate expression patterns to give still more sensitivity stimuli to customers. Thus this research disclosed conceptual and ideological background of surrealism and also analyzed and studied surrealistic expression features applied to the interiors designs of Contemporary Food & Beverage Space through expression disposition, study and classification of techniques. And standing on the result of analyzing surrealistic expression features of Contemporary Food & Beverage Space with a key word of expression features derived we groped for estatescape trend demanded in Food & Beverage Space and direction coming.
