Unlike other body arts, body painting illuminates the value of art using eco-friendly formative activity and natural environment and highlights the need of eco-friendly activity. However, although body painting has focused on forming right relationship between human beings and nature, there are few researches which are linked with nature art. Therefore, the purpose of this study is to argue the need to study body painting as nature art in connection with natural environment and analyze body painting according to nature art types. The study methods included both theoretical review and empirical review. The theoretical review examined the concept and characteristics of nature art through previous researches and literature and the empirical review looked into the types and works of nature art and applied them to body painting works. The results were as follows. First, an installation type was possible by arranging and attaching certain materials to the body. Second, a physical type was possible by representing body itself as the part of nature. Third, a symbolic type was possible by making body appearance as a some symbol based on artist's idea. Fourth, a sound type was possible by stimulating auditory hallucination using the nature of objects and sensing a sound. Fifth, an ecological type was possible by conveying the message of living things in nature to the body. Sixth, an interior type was possible by inducing indoor installation of works. Seventh, a poetic type was possible by making one feel a poetic inspiration expressed in nature using the mystery of the sea and a simple sequential pattern of floral leaves. Eighth, a drawing type was possible by adding artist's intentional hand with a pictorical technique. Ninth, a indigenous type was possible by reproducing South American indian's primitive style. The review of this study suggests that body painting works have been expressed in experimental and temporary arrangement like nature art in nature and can be applied according to nine types of nature art.

The chemistry has the academic system in which a concept is jointly developed into the single strain, so the contents of the chemistry I II of the high school are very important in the connection of the general chemistry in the university. At this moment, it is possible for high school graduates to be accepted into science or engineering majors without taking the chemistry II. These the highest intensive election subject cause problems of differences in level of understanding and difficult of quality educations. In this study, we have analyzed similarity between the contents of the chemistry I II and the general chemistry. We also analyzed the cognition level of students without taking the chemistry II in understanding the general chemistry level classes. We found that the high school level chemistry I and II introduced about 27% and 62% of the essential concepts required for the general chemistry, respectively. In a case of M university in Chonnam, about 70% of students in the general chemistry classes have no exposure to the chemistry II in their high schools, causing difficulty of understanding new subjects due to their insufficient concepts for classes. The lack of knowledge caused lowering of learning achievement and decrease of interests in chemistry.

Science Revolution, which stands for new paradigm in an era as a transfer, usually is accompanied with a change in intellectual sphere. Futhermore, as there is an indissoluble connection between science and an, so the correlation of two realm lead to mutual prosperity in coexistence. Recently, concerns for the phenomena of non-linear dynamics in science and its quick adaptation in art made .it possible. What is important agenda for science and art is to suggest the process of creative evolution and its method, I believe. In order to attain these, different and contra way of thinking, spirit of research and venture for unpredictable things out of daily routine should be indispensible. In this study, I am offering and reviewing the space design based upon phenomena of nonlinear dynamics, drawn from concept of chaos in physics and mathematics. This study places a great emphasis on nonlinearity which should be understood as a whole, not partially, that enable a designer to find new cosmos and principles of creation. In addition to these, I wish that a designer would stop trying partial apply in nonlinear space. In fine, I hope this study enables a designer to adapt and generate nonlinearity as creative attribute in space by understanding of phenomena of nonlinear dynamics and its process as a whole.

This paper analyzed the pedagogical content knowledge (PCK) presented in three novice teachers' mathematics instruction. PCK was analyzed in terms of the knowledge of mathematics content, the knowledge of students' understanding, and the knowledge of teaching methods. Teacher A executed a concept-oriented instruction with manipulative materials because she had difficulties in learning mathematics during her childhood. Teacher B attempted to implement an inquiry-centered instruction in the lesson of looking for the area of a trapezoid. Teacher C focused on the real-life connection to mathematics instruction. There were substantial differences among the teachers' PCK revealed in mathematics teaching, depending on their instructional goals. The detailed analyses of three teachers' teaching in terms of their PCK will give rise to the issues and suggestions of professional development for beginning elementary school teachers in mathematics teaching.

The purpose of this study was to investigate the effects of estimation strategy on placing decimal point in multiplication and division of decimals. To examine the effects of improving calculation ability and reducing decimal point errors with this estimation strategy, the experimental research on operation with decimal was conducted. The operation group conducted the decimal point estimation strategy for operating decimal fractions, whereas the control group used the traditional method with the same test paper. The results obtained in this research are as follows; First, the estimation strategy with understanding a basic meaning of decimals was much more effective in calculation improvement than the algorithm study with repeated calculations. Second, the mathematical problem solving ability - including the whole procedure for solving the mathematical question - had no effects since the decimal point estimation strategy is normally performed after finishing problem solving strategy. Third, the estimation strategy showed positive effects on the calculation ability. Th Memorizing algorithm doesn't last long to the students, but the estimation strategy based on the concept and the position of decimal fraction affects continually to the students. Finally, the estimation strategy assisted the students in understanding the connection of the position of decimal points in the product with that in the multiplicand or the multiplier. Moreover, this strategy suggested to the students that there was relation between the placing decimal point of the quotient and that of the dividend.

The basic theory and application of new adaptive finite element algorithm have been proposed in this study including the adaptive hp-refinement strategy, and the effective method for constructing hp-approximation. The hp-adaptive finite element concept needs the integrals of Legendre shape function, nonuniform p-distribution, and suitable constraint of continuity in conjunction with irregular node connection. The continuity of hp-adaptive mesh is an important problem at the common boundary of element interface. To solve this problem, the constraint of continuity has been enforced at the common boundary using the connectivity mapping matrix. The effective method for constructing of the proposed algorithm has been developed by using hierarchical nature of the integrals of Legendre shape function. To verify the proposed algorithm, the problem of simple cantilever beam has been solved by the conventional h-refinement and p-refinement as well as the proposed hp-refinement. The result obtained by hp-refinement approach shows more rapid convergence rate than those by h-refinement and p-refinement schemes. It it noted that the proposed algorithm may be implemented efficiently in practice.

The street system in multi-family housing is an important design element to control the circulation of vehicles and pedestrians, and to form the spatial organization of the projects. In particular, in the case of high-rise apartments, the street patterns have an influence on the safety, amenity, and convenience of facilities. Until now, however, the design of street patterns in most high-rise multi-family housing projects has diminished the quality of residential environments because priority of design consideration has primarily been given to planning road ways and parking areas. Nevertheless, the design competitions introduced for the first time in the 1980s have played a significant role in developing fresh ideas and concepts in housing design. Because street patterns have been respectably modified as a result of the generalizing of design competitions, it is important to review the ideas that have been proposed in competitions over the recent past. In this context, this study classified the types of street patterns and analyzed their design characteristics for the proposals of housing design competitions since the 1990s. As a result of this analysis, the road patterns are classified into 4 types: 1) serial type, 2) isolated type, 3) mixed type, and 4) not a road pattern due to the system of connection. In addition, these were further divided into 8 types: 1) loop, 2) ring, 3) penetration, 4) tree, 5) direct entry, 6) ring and penetration, 7) loop and penetration, 8) not a road pattern due to appearance and the collector.

The interconnectedness of all things is continuously expanding. For example, bluetooth low energy (BLE) beacons are wireless radio transmitters that can send an identifier to nearby receivers and trigger a number of applications, from proximity marketing to indoor location-based service. iBeacon technology which is one of the newest technologies in the smart tourism field, is reckoned as being very useful for travelers in enhancing the experience with visiting places. However, there is consequently not much existing research yet about the connection between iBeacon technology and tourism destination. Considering that, this study analyzes the adoption of iBeacon in tourism destination, this study examine the interrelationships and feedback structures of key factors in iBeacon adoption. To serve the purpose, this study used system dynamics approach to develop a model of iBeacon adoption in tourism destination. The analysis results showed that the concept of 'Social Influences' is one of the significant predictors for individual's intention behavior to accept iBeacon, and word of mouth (WOM), subjective norm, privacy concern, and perceived usefulness are key factors influencing the iBeacon adoption.
