The purpose of this study is to propose a new design concept and properties within new paradigm. Contemporary students of architectural design seem to redefine the mechanic and reductive approach to design method based upon Euclidean geometry. In this study, the organic space-time and holistic view-point that constitutes the background for all this is radically different from the modern design. It consists of three sections as follow: First, it presents a concept of complex system and properties of complexity that we find in new natural science and tries to combine that news geometry with architectural design to provide a methodological basis for morphogenesis and transformation. Second, the complexity in architecture is defined as a fractal shape, folded space, and irreducible organic system that cannot be fully understood by modernist idea of architecture. Third, the complexity in architecture is strategy based on the electronic paradigm that would enable the emergence of creative possibility. The complexity theory offer new insights to explain not only natural laws but also define dynamic architecture. In fine, this study places a great emphasis on the organic world-view to the spatial organization, which I hope will contribute to generating a greater number of creative possibilities for design.

The purpose of this paper is to investigate the significance and the role of intuitive model and the example of its development. Intuitive model is the tools of intuition in mathematics and the sources for the creative learning mathematics. It consists of the analogical model, paradigmatic model and diagrammatic model. Intuitive model must have a number features in order to be really useful as heuristic devices. It must present a high degree of natural, consistent and structural correspondence with the original. It must also correspond to human information processing characteristics and enjoy a relative autonomy with respect to the original. Sometimes, the difficulty in teaming mathematics stems from the abstractive characteristics of mathematics. So, we have to assist students' learning using the intuitive model that reveals the concrete representation and various changes of mathematical concepts, rules and principles.

The spreadsheet Microsoft Excel is the most widely used mathematical tool in today's workplace. Moreover, it is also an outstanding means for developing a surprisingly wide range of creative and innovative educational uses within such areas as mathematical modeling, visualization, and instruction. The spreadsheet's format provides us with a tool that closely parallels the way in which we naturally carry out problem solving, while the spreadsheet creation process itself illuminates the underlying mathematical concepts. In addition, the spreadsheet's visual layout allows us to introduce a broad variety of challenging and interesting topics, and to design creative demonstrations through eye-catching animated graphics. The material presented comes from actual classroom mathematics teaching experience in both industrially advanced and developing nations. A series of highly visual interactive illustrations from mathematics, the natural and social sciences, computing, engineering, and the arts provide a number of usable examples. The material discussed is applicable at diverse levels, ranging from schools and universities through adult education and in-service teacher development programs.

The main driving force behind Chomskyan theory of language that is gaining ground under the title of the "minimalist program" has been the urge to reduce the variety of natural languages to a minimal number of theoretical concepts and devices and to formulate the strongest possible hypothesis about linguistic structures. This has led to a long series of proposals of ever greater abstractness, with concomitant modifications in a number of theoretical constructs. The minimalist approach is the latest development of these constant changes, for which there is really "only one computational system and one lexicon," the differences among languages being reducible to parametric variation in "nonsubstantive parts of the lexicon"(Chomaky 1995:169-70). Chomsky thus differs, now more than ever, from other linguists by his sweepingly programmatic, rather than empirical, approach to language. The proposals he makes are too complicated to discuss here in any technical details. We rather focus on a series of lectures delivered by an ardent adherent of the minimalist program, with the view to demonstrating how this theory may mislead and distort the whole prospect of linguistic investigation. The rationale of the so-called 'minimalism' per se will be called into question.

Light environment and growth of Panax ginseng In habitat and cultivation under natural shade were renewed. Grower's experiences on ginseng stand In relation to light environment were assessed. Change of shading method and grower's concepts on light requirement of ginseng plant in Korea, Manchuria and Japan was counted. Growth of wild ginseng was better under rich light. Optimum crown density index appeared to be 0.7 In natural habitat and 0.4 to 0.7 for the cultivation in forest. Change of light Intensity in forest was greatest in May and reached near to constant value (from 40% to 3% for broad leaf deciduous forest and loom 4% to 2% for pine forest). Insufficient light condition induced long and thin stem, poor flowering and seed bearing, and sequent dormancy. Relation between light and ginseng strand was not clear but light Interception with cool weather was effective. Topography and orientation of bed have been deeply considered for light environment. Panel or bark of won were used for shading in deep forest manly In Manchuria while reed blind and straw thatch were used in Korea. Kinds and number of shades material and seasonal or daily schedule have been simplified probably by labor pressure due to eulargement of plantation. Post height has been greater while width of roof, bed and ditch has changed lisle. Scientific survey in the past omitted important light control methods (complete light hardening etc) which has been practiced in specific areas. The concept and technique of light control in the past in Korea were delicate and intensive including the control of temperature and moisture. For the application of old concept in modem cultivation precise Investigation of the technique including the measurement of light, temperature and moisture is needed.

The purpose of this study is to investigate existing world economic science theories and concepts of sustainable development as well as create original system of criteria and indicators to assess potential and conditions for sustainable development from a regional perspective and based on the above justify proposals for public authorities to improve methods of economic regulation for regional development. To achieve the goal evolution process of existing theories and concepts of sustainable development and "green growth" have been studied in terms of its adaptation to the spatial development of Kazakhstan, comparative dynamics of natural resources consumption in the Asia-Pacific region and Kazakhstan were investigated as well. Methodology. World best theory and practice methods for assessment of the level of sustainable development of the country and some of its territories were also studied. We selected the best system of criteria and indicators for assessment of economic, social and environmental sustainability of regional systems. Methods offered in this article are based on traditional and new factors of economic development and conditions for operation of regional systems. Indicators are chosen with a glance to basic goals for future development of regions in Kazakhstan. It is recommended to use two levels of methodology offered by author, namely national and regional, and at the local level later (districts, municipalities, cities). The results. Method offered by the author has been tested based on materials and statistics of regions in Kazakhstan. Suitability and usability of the proposed system of criteria and indicators for measuring of economic, social and environmental sustainability of regional systems was proved. Based on this analysis it was found out that there are regions in Kazakhstan that differ from each other by most of key indicators of sustainable regional development and this tendency is increasing. Conclusions and recommendations. As a result of this analysis, the authors have substantiated a number of proposals on methods of analysis to be used, improvement of methods of regional development, implementation of institutional reforms, as well as improvement of regional statistics. This article provides recommendations that can be successfully used in the management practices by public authorities to implement a new regional strategy focused on sustainable development in future.

The appropriate occlusion is one of the most important factors for the long-term success of implant and its restorations. The purpose of this review is to investigate and define occlusal considerations to reduce failure of implant prostheses. The physiological movement of implants is markedly lower than that of natural teeth and they also lack in occlusal sensitivity. Proper occlusal pattern may be assigned to compensate for the biological disadvantages and occlusal contacts must be formed where the cantilever effect is minimized. Moreover, the long-term success of implants after osseointegration can be assured by reducing early occlusal loading to avoid implant overloading and selecting appropriate occlusion material. Occlusal overload was brought by the number and location of occlusal contacts, which are under the clinician's control. The concept of implant occlusion is based on the concepts derived from traditional prosthetics. Moreover, there are few evidence on the concept or design of implant occlusion. Several occlusal design was recommended for implant prosthesis. Mutually protected occlusion, group function occlusion and bilateral balance occlusion was recommended for the specific types of implant restorations. This article reviews proper design of occlusion for implant restoration and offers occlusion strategy clinically.

"주역(周易)"은 우주세계 온갖 만물의 모습과 작용을 관찰하여 팔괘로 추상화하고 서법(筮法)의 수단으로 계산하고 귀납하여 인간의 일을 설명하고자 하였다. 이 논문은 '관찰', '계산', '귀납' 등의 측면에서 "주역" 과학적 사유의 원류를 발견한다. "주역"의 자연과학적 사고는 근대과학을 주도하였던 서양의 사유방식과는 구별된다. 서양과학에서는 대상을 원자로 분리하고 인과적으로 분석하여 자명한 결론을 도출하려 하였지만 "주역"은 만물의 동태적 기능과 변화를 관찰하고 연구하여 종합적으로 통섭하려 하였다. "주역"의 사유방식이 근대과학의 발전 단계에서 긍정적인 기여를 하지 못하는 동안 서양의 과학방법은 16-17세기의 계몽시기를 거치면서 중국을 압도하여 현대에 이른다. 이 논문은 "주역"에서 발견한 과학적 사유의 흔적을 통해 그것이 현대과학의 이론들과 공유될 수 있는 지점을 논한다. 그 근거는 "주역"에 제시된 자연관찰과 방법론 등이다. 나아가 "주역"의 주요개념들에 나타난 현대자연 과학적 함의를 고찰한다. 이 논문에서 제시하는 논지는 크게 나누어 두 가지이다. 그 하나는 "주역"이 과연 과학인가 라는 의문에 대한 것이고 다른 하나는 원시 과학으로 시작한 "주역"에서 현대 과학적 사유를 발견하여 그것을 예시하는 것이다. 첫 번째 과제를 위해 과학역(科學易)의 역학사적(易學史的)의미를 검토하고 "주역"의 자연관찰과 자연과학 방법론을 고찰한다. 두 번째의 논증은 원시과학에서 근대과학 및 현대과학으로의 변천에 있어 그 과학적 인식의 변화가 "주역"의 인식과 어떻게 차이점을 가지는지 혹은 유사점을 가지는지 검토하여 "주역"과 현대과학에 나타난 특징을 비교 고찰한다.
