The aim of this study is to clarify the process of the sound changes of Japanese consonants (Dakuons) in the analysis of the transcriptions of Korean Source-Materials (i.e. Japanese textbooks for Korean and the records of travel in Japan) written in the 15-l8th centuries with the Korean writing system. Especially these records of travel in Japan are meaningful in that the process of change of Dakuon is shown in detail. The results are as follows. 1) In the 15th century, all Dakuons /g d z b/ had nasality. 2) The nasality of /z/ and /b/ disappeared in the 16th century. 3) The nasality of /d/ disappeared in the late 17th century.

The findings in contrastive rhetoric research of the twentieth century have shown that different cultures have different conventions in organizing written texts. These culture-related conventions were claimed to influence English texts written by L2 learners, including Asian learners of English. However, due to the massive inflow of the American culture into Asia as well as increased exposure to English in the midst of globalization of the last decade, it is quite probable that the textual gap between the native English writers and Asian EFL writers have been reduced. The present study investigates the changes that have taken place in EFL writer's knowledge of genre-specific writing over the past decade. To this aim, this study compared four sets of application essays written by four groups of applicants (1) native American applicants in 1993, (2) Korean EFL applicants in 1933, (3) native American applicants in 2003, and (4) Korean EFL applicants in 2003. The results suggested that the disparity between the Korean EFL writers' and the native English writers' texts were becoming less noticeable at the macro-level, possibly due to Korean EFL writers' enhanced textual awareness of English genre structures Pedagogical implications are discussed.

Teacher written feedback on student compositions has received tremendous attention in second language (L2) writing research. Notwithstanding the importance of understanding both teachers' and students' perspectives on the feedback process, much of the feedback research has only looked into one-side of the story - adopting either the teacher's or the student's perspective. The current study is an attempt to look into both sides of the story by examining the types of written feedback that students prefer, the extent to which students' preferences and teachers' actual feedback practice overlap, and the extent to which student perceptions of teacher feedback coordinate teacher self-reflections on their feedback practice. Three English composition classes (3 teachers and 46 students) at a university participated in this study. It analyzed student and teacher data from questionnaires and teacher written feedback on student compositions. The results showed that students' preference for feedback on global and local issues varied across the three composition classes. This is partly a consequence of how students perceived the type of feedback that their teachers practiced. Teacher self-reflection on and student perception of teacher written-feedback generally coordinated. These findings are discussed in light of how contextual factors affect learner perception of teacher written feedback and underscore the need for examining students' reactions to feedback and teacher self-reflection.

Usage and scope of the word Bibliography in comparison with in conventional Chinese Catalogue (中國 在來 目錄學) (1) Usage of the word in connection with the study of books in the West has been changed from 'writing of books' (17th century) to the meaning of 'study of a book as an object'(l8th century), and this meaning of the 18th century has been transmitted up to the present. (2) In its scope, 14 branches(eight in physical aspect, six in content of books) were set up independently for the study of a book as an object. On the other hand, the term Textual Bibliography(校수學) was in use in China before the Opium War, however the word Catalogue (目錄學) has been a current word for the subject study as in the case of Bibliography in the West. And in the scope of study of a book as an object, although some of its aspect is somewhat similar to the Occidental Bibliorgraphy, the main stream of learning is regregarded as the root and the physical aspects as branches and lea leaves, thus the latter has been treated with less importance.

In the present study, biomass pyrolysis was done using five different kinds of catalysts with change in the support species and their compositions. Ni was loaded on alumina, ceria and alumina-ceria supports using co-precipitation method. In all the catalysts, 30wt% of nickel was loaded on the support materials. The paper used in daily writing purposes was taken into account as biomass sample. In the experiment, 19 of biomass was mixed with o.1g of each catalyst separately. Thermogravimetric analysis (TGA) was performed with all the catalysts diminished the initial degradation temperature of paper biomass sample considerably. During the pyrolysis process, the temperature was raised from room temperature to $800^{\circ}C$ with the heating rate of $10^{\circ}C$/min in the furnace. The cumulative $H_2$ volume had reached the best value of l4.02ml with the Ni/$Al_2O_3-CeO_2$ 30wt%/(50wt%-50wt%) catalysts. In presence of all the catalysts, the highest amount of $H_2$ was produced at $800^{\circ}C$, 10min. of residence time.

The historical development of books examination with utilizing science become inevitable to the machanization of library catalogues. With the advance of times, like this, a new- development of $Indention('||'&'||'$ : Kisun) must be sought for which is a kind of descriptive catalogues being used now. This paper is scheduled to grasp problems in the course of using and logical grounds of Indention which hal-e been used disordering. It must be considered that four kinds of Icdention settlement is suitable to the features of Korean letters. 1) TI-e must consider the features of Korean Language and Oriental Language writing(Japan, China). There must be a establishment of floating $Indention('||'&'||'E$ : Kisun), which are suitable for the writting style or hand writting man on the point of most of Koreans are depend upon hand witting, then books catalogues like western language, not left edge of the cards of the $Indention(B$ : Kisun) establishing, from edge to Call Number, from the last of the Call Number to First Indention(%-Bl63). First Indention(%-%%) to a space of Second $indention($\ulcorner^%)$ must be established and then, every catalogue and Indentions are distinguished surely. 2) \Then we consider the developing catalogue making in the future. It is important to establish a fixed $Indention('||'&'||'$ : Kisun) for machinization of typewriter(Korean, Mimeographing) and computer, etc ... not "Cm" unit but "Space" unit, and consider oriental letter, ne make more surplus space as a Indention, we can give anadaptablity of using machines. 3) Considering typography printing and type-setting printing by printing type, we must fit the $Indention(\ulcorner'||'&'||'$ : Kisun) as a "Cm" unit, and there must be a re-adjustment of $Indention(g$$ : Kisun) which considered the complexity of Call Number by a mass of collecting books like this, the establishment of Indention(E'||'&'||'j!: Kisun). We must not use a uilified one as a concrete conception by "Space" or "Cm" unit which has been used now but re-adjusted adaptably which can be fited as a method of making of catalogues. 4) The name of $Indcntion(J, S$ : Kisun) has becll called 7;arious methods until now, but English Indention which has been used without any concrete mexirig must be used as a ours fitable as a our mind. The above mentioned is presented as a Indention and examinational l~letilods by myself style, I wants these r i l l be helpful to the future developments of the machanization of Indention $(sf:$ Ki sun). Concrete studies must be continued in the future for development of $Indention(zj:$ : Kisun). : Kisun).

Following a joint OECD/NEA-IAEA-sponsored meeting to define the current role and future perspectives of the application of Computational Fluid Dynamics (CFD) to nuclear reactor safety problems, three Writing Groups were created, under the auspices of the NEA working group WGAMA, to produce state-of-the-art reports on different aspects of the subject. The work of the second group, WG2, was to document the existing assessment databases for CFD simulation in the context of Nuclear Reactor Safety (NRS) analysis, to gain a measure of the degree of quality and trust in CFD as a numerical analysis tool, and to take initiatives to extend the existing databases. The group worked over the period of 2003-2007 and produced a final state-of-the-art report. The present paper summarises the material gathered during the study, illustrating the points with a few highlights. A total of 22 safety issues were identified for which the application of CFD was considered to potentially bring real benefits in terms of better understanding and increased safety. A list of the existing databases was drawn up and synthesised, both from the nuclear area and from other parallel, non-nuclear, industrial activities. The gaps in the technology base were also identified and discussed. In order to initiate new ways of bringing experimentalists and numerical analysts together, an international workshop -- CFD4NRS (the first in a series) -- was organised, a new blind benchmark activity was set up based on turbulent mixing in T-junctions, and a Wiki-type web portal was created to offer online access to the material put together by the group giving the reader the opportunity to update and extend the contents to keep the information source topical and dynamic.
