Recent interaction research has shown that corrective feedback may benefit L2 learners to varying degrees, and that certain types of feedback may be more beneficial than others, engendering much discussion and research attempts to investigate the issue. Goo`s (2012) study is one of those empirical attempts conducted in this line of research paradigm. The present study, as a conceptual replication of Goo`s original study, explores this on-going area of feedback research, the relative efficacy of different forms of corrective feedback, and whether/how phonological short-term memory (PSTM) mediates the impact of different feedback moves on the acquisition of the English that-trace filter. Twenty-nine adult high-intermediate Korean EFL learners were randomly assigned to one of three groups: a recast, metalinguistic feedback, and comparison groups. The study employed a pretest-posttest design. One intensive treatment session was implemented. Two dependent variable measures were developed/administered to assess learner performance: a timed grammaticality judgment test and a timed oral production test. Overall results showed that metalinguistic feedback was more effective than recasts at facilitating the acquisition of the target construction. PSTM was not found to be correlated with the effectiveness of recasts and metalinguistic feedback. Different patterns of learner performance were also observed depending upon the mode of dependent variable measure.

In the present study, we aimed. to consider the name of twelve main Meridian in order to understand the concept of the Meridian system and to applicate acupuncture theory in the clinical field properly and fundamentally. We referred to several literatures on the matter and we found out that the name of present twelve Meridian was not settled until the period of Yellow Emperor's Classic. In the time of Yellow Emperor's Classic, the two theory of Internal Organ and Meridian system were combined and added new theory of 'WoonGi'. The general rule of combination is that the component of name of Meridian consist of 'Hand' or 'Foot', 'three Eum and Yang' and internal organ. The internal organ coupled with the root ki or middle ki of 'three Eum and Yang' and the 'Hand' or 'Foot' depend on the location of internal organ that belongs to meridian. The name of Twelve Meridian is a kind of system formed to analyze the two concepts organically and dynamically. One is material internal organ and the other is immaterial meridian system.

Purpose : The primary aims of this retrospective study were to compare subjective bone quality and bone quality based on the Hounsfield scale in different segments of the edentulous jaw, and to establish quantitative and objective assessment of the bone quality. Materials and Methods : Twenty eight randomly selected cone-beam computed tomographic (CBCT) scans were analyzed. For evaluation one hundred and twelve edentulous areas were selected. Implant recipient sites were evaluated visually for Lekholm and Zarb classification. The same sites were subsequently evaluated digitally using the Hounsfield scale with Vimplant2.0, and the results were correlated with visual classification. Data was subject for statistical analysis in order to determine correlation between recorded HU and the regions of the mouth with the Kruskal-Wallis test. Results : The highest unit/mean density value (311 HU) was found in the anterior mandible, followed by 259 HU for the posterior mandible, 216 HU for the anterior maxilla, and 127 HU for the posterior maxilla. These results demonstrate a strong correlation for HU depending on the region of the mouth (p<0.001). The relationship between HU and type 4 bone was found to be significant (r=0.74). Conclusion : Knowledge of the Hounsfield value as a quantitative measurement of bone density can be helpful as a diagnostic tool by using CBMercuRay with Vimplant software.

Methods for the treatment of foul odor was physical, chemical and biological. In this study, we utilized biofilter for the treatment of foul odor. Importance factors of a microbe is nutrients, temperature, moistrure and pH. As the results, it was found that matter of the odor was trimethylamine, removal rate(η(%)) fo (CH₃)N₃ appeared 19.7%∼96.5%(site-1), 20%∼95.5%(site-2) after treated to the biofilter, and tended to decrease from 7 months later by a biofilter compaction. Also size of the tree chip was 2cm, degree of the foul odor was degree of 3∼4, propriety temperature was 20∼40℃, the rate of contained moisture was 60∼70%, acidity was pH=8.

A Study on the writer and story-writing date of Hanmoonchunhyanggeon is one of our major researches in classical as and important process of organizing Chunhyanggeon. so, I world like to render great academic advance in studying writers and story-writing date of two texts of Hanmoonchunhyanggeon which is diverse in opinions in academic circles. Conclusion of this paper are as follows ; The story-writing date of Chunhyangsinsul is 1864, and the writer is not Teo-lim Mok who is insisted by some scholars in academic circles but unidentified right now. And the first edition date of Heuntohanmooncunhyangeon is 1917, and Chul-Gin Wu who si recognized as a writer is regarded as an ordinary publisher. I believe these conclusions can devote much help in studying Chunhyanggeon and discussing aspects of Gookmoonchunhyanggeon and Hanmoonchunhyanggeon in the future.
