Water is the origin of all things and has been standing as a symbol of eternity which neglectes birth and death, or time and space. We mankind , however, confronts the water pollution or moreover the situation threatening even our existence as the results of considering it as mere consumables without any study on its original meaning or nature. Now, we should search for the way to understand the substance of water and to use it in the course of nature, getting rid of the altitude of merely consuming it. Our traditional way of life is in harmony with the nature and water has been adopted in the space as the important element of the nature especially as per the theory of geomancy. Man can be inspired by the plasticity , motion, sound , and reflectivity of water adopted and harmonized in the space, and the concept such as water both of inner and outer space or hierachy of a microcosmis to be composed by the natural order which lines up a man-water-space.

This study is to suggest the technique of ecological park to compatible mountain ecosystem near the urban in Woomyeonsan Urban Nature Park. It was proposed to differential technique from established ecological park focused on changing the cognition of nature, wetland ecosystem protection and restoration, and studying by served sound leisure program(nature observation and experience, etc.), in compatible mountain and urban forest near the Urban. Firstly, to achieve this aim, it was carried out delicated research and analysis that were the angle of inclination, trail, fauna, actual vegetation, bird and insect, and then to selected nature trail course and analysis capability through it.. In the basic concept and plan, firstly to make park aid mark and foundation mark, and then to establish the detail programs, nature observation program, management and organization program. This site where valley and mountain coexist was highly capable but whole site was very steep, so usable area is very narrow. To make Woomyeonsan nature ecological park escape from the established wetland type, ecological park and the park of event have to use nature material and introduce visitor. To establish it as the Nature Culture observation park and reflect on forest, valley of Woomyeonsan was divided into three display places; Nature ecosystem Zone, Meditation Zone, Nature Culture experience Zone and Nature Culture observation Center. For satisfying with ecological park aid mark and foundation mark, it was proposed to settle management plan for volunteer control and organization composition.

Matched field localization schemes often show a high sensitivity to acoustic variabilities due to mismatch between assumed and actual environments. In this paper, we focus on the effect of source motion or Doppler on matched field processing (MEP). to accomplish this, MFP is extended to treat a moving source problem with normal mode description of the sound field. the extension involves both the temporally nonstationary and spatially inhomogeneous nature of the sound field generated by a time-harmonic point source moving uniformly in a stratified oceanic waveguide. It is demonstrated that the impact of source motion can be significant to MEP although the velocity of a moving source is much smaller than the sound velocity of the oceanic waveguide. In addition, a criteria for minimizing the effect of Doppler on MFP is discussed.

In this study, examined heavy-weight floor impact sound to structure that have slab thickness of 4 form at a standard laboratory through noise and vibration measured. The results show that the nature Natural frequency increased according to change of thickness of each slab by finite element analysis, and acceleration value decreased. Results of measurements of noise and vibration at a standard laboratory, the slab 210, 240mm structures was construed result such as finite element analysis but the slab 150, 180mm structures is construed that influence in vibration acceleration level because edge condition has condition that contact to ground. Therefore, in modelling process for analysis, is thought that need that condition analyzes examining element influencing about structure that contact to ground.

This paper implements a smartphone application for sound recording and player of mobile learning. Due to its ubiquitous nature, smartphones could be used anytime anywhere, and because they combine an audio and a microphone, the application for sound recording and player that this paper suggests can be easily and cost effectively developed without additional infrastructure. This paper also explains a technique which processes data of music lyrics. The technique is built on a database technology by using SQLite, a DBMS combined in a platform of android. Thus, as long as the smartphone application for sound recording and player is developed and the mobile phone has sound source files, learners could record their own voices to the sound. Therefore, we expect the learners without additional infrastructure to enable mobile learning.

This paper deals with the nature and function of intensification in Korean in a wider scope of intensification which was not paid proper attention including intensification in the initial position as well as middle position. Unobserved new areas of intensification in the initial position are paid more attention like sound split of polysemy e.g. (s'eda), (kyongk'i) by means of intensification and north Korean application of intensification on (wonsu) and intensification of borrowed English. The recent phenomenon of ‘gwua’ intensification is experimented on two groups of people, young students and old people beyond 65 years old by means of sociolinguistic analysis. The result shows that its intensification is a form of student violent power and a mark of extreme solidarity among activist students. Thirty three university students(male 16, female 17) are asked to explained to write the meanings(feelings or when to use, etc.) of the words which have normal form and intensified forms. The results show intensification attaches the meaning of ‘emphasis,’ to bring the extremely polarized emotion: samll to the smallest, exact to the perfect exactness, bad to the worst feeling. Four words are being split to express different meaning with the word intensified. In conclusion, the nature of so called saisiot(t) e.g. intensification is voiceless tensed pause and its functions are the polarization of the original meaning of the word, sound split of polysemy and attachment of social values by intensification.

Presence of music in the modern game is getting bigger and bigger, and storytelling in the area of game play a leading role in many cases. Platform game is one type of action game genre. In its nature, the character and the object in a game are closely coupled, thus they have intermate relation with reactive sound system. In this study, we tried to build a effective and reactive sound system which is suitable for the storytelling of platform game. In addition, we speculated various aspects of game including psychological, musical and social aspects, finally investigating the future aspects of the game music.

Carious dentin can be classified, on the basis of their clinical characteristics, into three groups; sound, sclerotic and active carious dentin. Active carious dentin differs from sclerotic dentin by its abscence of variable bacteria within tubles and amount of chemical content. But the apatite molecules of active carious dentin are not fully studied. The purpose of this study was to observed the physico-chemical characteristics of deep carious dentin. The samples of sound, sclerotic and active carious dentin were obtained respectively from 300 freshly extracted carious teeth. Bacterial-rich zone of superficial soft dentin layer was removed with hand instruments from all samples in advance. The samples were powdered and sieved (200 mesh) before analyses. Identification and estimation of the crystallinity of the samples were carried with X-ray diffraction and infrared absorption analyses. Measurements were made on a Rigaku Denki (Rigaku, geiger flex III, Japan) X-ray diffractometer with Cu-target at 30 Kv, 30 mA and are traced on a monochromatic tracer. Infrared absorption analysis was made on FT-IR spectrophometer (Nicolet Instrument Co.) using KBr pellets containing the samples and was recorded on data process (Model IR-80. Nicolet Instrument, Co). The following conclusions were as follows; 1. The nature of the main inorganic structure of sound, sclerotic and active carious dentin proved to be hydroxyapatite. 2. It was difficult to determine the identification due to their crystallinity of sound, sclerotic and active carious dentin. But sound dentin was the highest in crystallinity among them. 3. The magnesium whitlockite was to be found in active carious dentin, but not in sound and sclerotic dentin. 4. The carbonate content was highest in sound dentin, but the lowest was in active carious dentin.

This study investigated the elements of soundscape in and around the traditional Korean style housing complex and the standardized Korean style housing complex popularized as farm village by Traditional Korean style housing assistance policy located in the rural area of Jeollanam-do. The purpose of this study is to understand the phenomenon and characteristic differences of the sound environments in various observation points in order to utilize them as the important elements of sound scape to consider for standardized Korean style housing complex development in the future. As a result, the traditional housing in rural area led more positive evaluation of nature sounds than standardized, newly developed Korean style housing complex. In the list of noises in each residential development type, traffic sounds and construction noise were majorly ranked. However, nature sounds had high rate of response in the sounds of introduction request. Additionally, the sounds generated by human activities such as whispering and footsteps were also in the wish list. This may suggests that soundscape design needs to approach in cultural level of a society rather than simple investigation and treatment of individual sounds of natural and artificial.

Recent literature in science education has emphasized nature of science in science teaching. The theme has been considered to be an important element for scientific literacy.The purpose of this study was to identify Korean science teachers' points of view on topics related to nature of science, such as definition of science, characteristics of scientific hypotheses, scientific theories and scientific laws, and their construction, scientists, and scientific methods. The relevant 13 items were selected from Views on Science-Technology-Society (VOSTS) by the authors for this study. Most teachers perceived science as an exploratory process or problem solving. Some perceived science as an application of knowledge to make this world a better place to live in. Teachers viewed scientific activities as scholastic and individualistic instead of pragmatic or collective. They did not hold clear understandings of the idea that scientific knowledge is subject to change. As identified in previous studies, teachers thought that scientific ideas develop from hypothesis to theories, and finally to scientific laws. They did not show sound understanding of inventiveness of scientific hypotheses and theories, nor discovery of scientific laws. In summary, teachers' major points of view reflected 'realism'. It suggested that they needed to understand nature of science in the ways which it has been described in recent literature of science education, in order to teach science with personal and social contexts.
