The perception of landscape structure can he formed mode clearly, with including an auditory stimulus to a visual aspect. The waterfall, as an landscape element, will be considered of not only it's function and structure in landscape architecture designing but also harmony with environment which it has been situated, and contribution to the public goad. The purpose of this study was to establish more 7rational and practical design theory for the construction of waterfall. The number of subjects investigated were 47 of waterfall located in Mt. Palgong. In this study, the acoustic character of the waterfalls were investigated as an excellent effect to mask easily sensible noises. The correlations between the structure of waterfalls and water 1a17ing sound, which were useful for waterfall design and construction, were examined. It was discovered that the position of double distance of waterfall height From the waterfall is significant in the visual and acoustic perception of waterfall.

Speech-print mapping awareness is defined as the awareness of the principles underpinning how speech sound is matched to print symbols. Chinese is unique in that it follows the one syllable one character mapping principle. The present study examined the predictive power of speech-print mapping awareness in young children's word reading. Seventy-four Hong Kong children from the first and second kindergarten years were tested with phonological awareness, visual skills, syllable-level mapping awareness, and Chinese reading ability at Time 1. Chinese reading abilities were tested again 1 year later. It was found that syllable-level mapping awareness predicted Chinese word reading abilities 12 months later. Further, it seemed that the link of syllable mapping to Chinese reading is particularly significant for beginning readers. The findings suggest that understanding the language-specific speech-print mapping principle is critical for reading acquisition at the early stage of reading development.

This study examines the recognition of the user's sound command based on speech recognition and natural language processing, and develops the natural language interface agent which can analyze the recognized command. The natural language interface agent consists of speech recognizer and semantic interpreter. Speech recognizer understands speech command and transforms the command into character strings. Semantic interpreter analyzes the character strings and creates the commands and questions to be transferred into the application program. We also consider the problems, related to the speech recognizer and the semantic interpreter, such as the ambiguity of natural language and the ambiguity and the errors from speech recognizer. This kind of natural language interface agent can be applied to the telephony environment involving all kind of communication media such as telephone, fax, e-mail, and so on.

The purpose of this study was to provide basic data on preschool children for accident prevention and to improve their health through a sound, safe living environment with safety education established through more systematic methods. Data were collected from 516 preschoolers from 4 to 6 years old using APP paper test which consists of a question and drawing. The children's general characteristics and accident proneness prospect were investigated. The relationship between the children's general characteristics and the accident proneness prospect were analyzed. The findings of the study are as follows : 1. The institution which children attended had a significant difference in accordance with the living safety (p=.015) and behavioral character(p=.033). 2. The housing pattern in which children lived had a significant difference in accordance with the movement speed(p=.027). 3. The children's age had a significant difference in accordance with the living safety(p=.002), traffic safety(p=.001), the reasoning power(p=.000), movement speed(p=.00), movement stability(p=.000) and attentional power(p=.000). 4. The children's sex had a significant difference in accordance with the movement stability and behavioral character (p=.003, p=.008). 5. The children's past accidental experience had a significant difference in accordance with the behavioral character(p=.001). 6. General assessment of the APP test had a significant difference in accordance with the children's age(p=.000) and children's past accidental experience(p=.020).

When Chinese character used in Korea, so did the characters' pronunciation, so many Korean Chinese characters today have similar pronunciation with Chinese, but since Korean and Chinese pronunciations were preserved and developed in different alphabets, the written letter of the pronunciation also differs. This study on Chinese education, has constructed and implemented an easy way to study Chinese pronunciations by creating conversion rule set between Chinese pronunciation, Chinese Hanyu latin Pinyin and Korean chinese character pronunciation consisting of an initial sound, a medial vowel, and a final consonant. This study has established web version and application version of this conversion rule set education system to enhance Chinese education.

Street fighter II is a game that played an innovative role in the genre of fighting games in the 1990s. There are many elements that this game has played, but I would like to describe the character's background music. Is terms of sound, it is an excellent game with theme music suitable for twelve characters and voice that comes out when using each character's technique. Street Fighter II shows different patterns of background music depending on the charcater's fitness. I analyze it in harmonical way and try to study it form the perspective of music psychology.

In order to build a quiet and comfortable ship, the noise levels on board ship must be predicted at early design stage. Statistical Energy Analysis (SEA) developed by R. H. Lyon has been well known to be the most useful frame work to study the energy flow of noise and vibration in structure. This paper applied this theory to predict the transmission loss of structure-borne noise of model structure and has developed computer program. Components constructions model structure have been all considered as SEA elements. And we also estimated the SEA parameters from the model structure. Using SEA and a new conception of STL, we found the transimission character of structure-borne noise theoretically by the idealized ship model, and then compared the results with three cases.

Suction muffler is one of the important component of a compressor for low noise level and high efficiency. The suction muffler which has the complicated flow path gives the higher transmission loss of sound, but lower efficiency of compressor results from the superheating effect and flow loss in suction flow path. It is shown that the computational analysis of fluid dynamics are very popular methods for designing of high performance and low noise suction muffler. To reduce the thermodynamic and flow loss in suction process, the flow path of suction muffler was estimated by FVM(Finite Volume Method) and verified by experiments. And to enlarge the transmission loss of sound, the acoustic properties inside the suction muffler was analyzed by FEM(Finite Element Method) and experiments. The smart muffler which gives a good efficiency and low noise character was developed by using those methods, and the effect was evaluated in compressor by experiment.
