It is requures to understand the meaning of sound and cultural background of target spaces for soundscape design. The purpose of this study is to derive the general soundscape preserved in the mind of Korean people. Four kinds of traditional Korean songs, that is to say, Sijo (Korean verse), folk-song, Pansori (song for drama by Chang reciter), and popular songs, were used as tools of research subjects. That is because the sounds expressed in literature are very useful subjects for soundscape survey. Paragraphs containing description of sounds were selected from the lyrics of the songs. Then 11 sound categories were named, and 13 meaning categories were classified according to referential and emotional aspects, respectively.

This study is to investigate the characteristics of space constitution by analyzing the Jungja in the Gasa (an old form of Korean verse) literature area. These Jungja architectures were composed at Damyang-gun and all over Mt. Moodeung in Chosun dynasty. It can be found several characteristics through 10 Jungja architectures. As a result of analysis, the conclusion of research is as follows. 1. There is a spatial function of Byulsu where the daily life can be managed. 2. The development of introduction part induces a concept of private space. 3. It has structures with openings that can form the various constitution of space. 4. There are heating facilities that people can spend their time in four seasons.

Using literary and educational points of view, this study examined the prizewinning poems for children in the Annual Literary Contest sponsored by the Dongah-ilbo and the Chosun-ilbo between the 1970s and 2001. The average age of both male and female writers increased over time, 82% were college graduates, and 54% were educators. All of the poems referred to nature in some ways, either as the major theme(42%) or in passing reference to some aspect of nature(58%). Onomato-poetic words were used in 71% of the poems; similes and metaphors were expressed in 13% and 51%, respectively; 58% were written from a mediator's point of view; 59% were in the present tense; 78% of the space elements were fixed; and 98% were written in free verse. In conclusion, the poems for children of the Annual Literary Contest should be used in literary education with guidelines for the appreciation, creation, and criticism of poems for children.

According to our fatigue tests carried out at 20 Hz, R=0.1 on transversely butt-welded joints, fatigue strengths of as-welded specimens, that is, specimens having residual stress are higher than those of annealed specimens in short life range, but vice verse in long life range. This behavior seems to be concerned mainly with residual stress relaxation by applied loading. After analyzing the welding process, we conducted finite element analysis to quantify the degree of residual stress relaxation. By taking into account residual stress relaxation, modified Goodman diagram, and nominal stress, we evaluated the fatigue life of the welded joint from the S-N curve for the parent material. The estimated results are in a good agreement with the experimental results.

Group buying is one of the most popular transaction patterns on the internet at least in Korea. Nevertheless, it is hard to find academic researches for it in view of consumer behavior. In this paper, we analyze factors which determine consumer's attitude toward and intention of participation in Internet group buying by comparison of Internet individual one. For this purpose, we propose “lowering price”, “decreasing risk” and “reducing transaction cost” as relative advantages and "lack of product assortment" and "delay of time" as relative disadvantages over individual buying on the Internet. For empirical test, Internet users who have some experiences of individual buying but not group ones on the Internet are surveyed and analyzed. In result, a satisfying model fitness for structural equation model is derived and most hypotheses except the relationship between "decreasing risk" and "attitude toward Internet group buying" are accepted. Our results provide not only academic contribution by suggestion of a research framework but also practical insight by discussion of diverse features in Internet group buying.verse features in Internet group buying.

We have synthesized novel Diphenoquinone(DQ) derivatives. Electron drift mobility of DQ series was measured and electron affinity$(E_a)$ of them is estimated 3.7~3.9eV by CV. Electron drift mobility$(\mu)$ of electric field dependence by time of flight(TOF) technique is $1.76{\times}10^{-5}cm^2/V{\cdot}s$(DQ5) at the concentration of 10wt% verse poly(4,4'-cyclohexylidene diphenylcarbonate)(Pc-Z) and $1.66{\times}10^6V/cm$.

The multimedia community needs an environmental data representation and interchange mechanism which not only satisfies the requirements of today's systems, but can be extended to meet future data sharing needs. This mechanism must allow for the standard representation of, and access to data. The SEDRIS STF(SEDRIS Transmittal Format)provides environment data users and producers with a clearly defined interchange specification. In this paper I develop data converter commercial data(3DS MAX) format to standard interchange format and vice verse without losing semantic of information content using SEDRIS standard interchange format.

The fiber morphologies of the textiles from the burials of the Seip group of Ohio Hopewell (ca. 100 B.C. to A.D. 500)mounds were examined using light and scanning electron microscopy. A theoretical model was proposed which delineates the rate of morphological change in fibers through time and the cultural activities which occur during the life of a textile element. The Seip textiles were categorized according to their visual and structural characteristics. The microscopic examination of the Seip textiles yielded the evidence of animal hair fibers and bast fibers. The animal hair fibers of the seip textiles were identified as the hair of rabbit or hare. The bast fibers of the Seip textiles exhibited variation in morphological features such as the degree of bundle separation and the presence of transverse striations, fibrillations, or trans-verse cracks.

The effects of the stabilizing additives such as NaCN, 2-MBT and Thiourea on bath decom-position, plating rate and surface morphology have been studied. Bath stability was increased in the order of an additive-free bath, and NaCN-, 2-MBT-, and Thiourea-stabilized baths. The sta-bilizing effects may be attributed to the stability of Cu(II) -complexes. The plating rate is the re-verse order of the bath stability. Accelerative effect of 2-MBT in proper quantity(0.3mg/$\ell$) may be explained by visualizing it absorbed through benzene ring or sulfur atom on portions of the sub-strates. The strong bond of the complexing part of the molecule to nearby chelated copper ions would tend to accelerate plating by making it easier for the Cu2+ -ligand bond to be broken. Sur-face morphologies of copper deposits depend on the bath additives. Electroless copper deposits from the 2-MBT stabilized baths are finer than the deposits from the NaCN- and Thiourea- stabi-lized baths due to the strong adsorption on the substrates.

The purpose of study was to introduce and propagate the children's verses as the teaching/learning strategies in science education far elementary students and teachers. 238 pre-service teachers, 140 in-service teachers and 602 elementary students wrote the own verses and read colleague's verses with respect to science. In this situation, the writing was considered as creation and the reading was reception and appreciation for the verses. When they wrote the verses, the themes were not restricted except that they were related to science. Mostly, the subjects were something about science concepts, scientific phenomena or experimental instruments, etc. In addition, this study investigated the merits and demerits of the reading/writing activities of children's verses as the teaching/learning strategies in science classroom.
