Even if odorous compounds remain very low concentration in water, it cause strong odor. Because Geosmin and most of odorous compound had very low vaporization, those were difficult to analyze with GC/MSD and Purge & Trap. So, we needed pre-treatment method for decreasing amounts of extracting solvents, improving recovery efficiencies and increasing analytical efficiencies. This study developed efficient technology for analyzing odorous compounds, using various adsorbents and extracting solvents. The optimum adsorbent was XAD resins. Especially, XAD-2, XAD-7 and XAD-2010 were superior, but XAD-2 of these and the optimum extraction solvent is MTBE. Other extraction solvents' efficiency is in order of MTBE>Dichloromethane>n-Hexane>Diethylether. The optimum NaCl dosage for increasing efficiency is 5 g in liquid-liquid extraction method. The shaking time(0~24hr) has no concern with adsorption efficiency. The optimum adsorbent is XAD-2 resin and extraction solvent is MTBE. Dosing NaCl, adsorption efficiency is increased in liquid-liquid extraction method, but NaCl has no effect on liquid-solid extraction method. In this experimental results, this algae toxins(Mycrocystin, Anatoxin etc.).

In order to investigate the effects of 70% EtOH extract obtained from Hovenia dulcis Thunberg on enzymes relating reactive oxygen intermediate, cancer-stricken animals induced by DEN (N,N-diethylnitrosamine) were recovered by administering the extract of Hovenia dulcis Thunberg. It showed that there was no effect on the generation of superoxide radical by the extract of Hovenia dulcis Thunberg. However, considering the increase of the activity of Cu, Zn-SOD and Mn-SOD in the tested animal class, the extract of Hovenia dulcis Thunberg could participate directly in removing of superoxides. The experimented-animals treated with the extract of Hovenia dulcis Thunberg showed an increase in the activity of the enzymes, catalase and glutathione peroxidase, which can eliminate hydrogen peroxide pertained in liver tissue. The extract of Hovenia dulcis Thunberg seemed to have some factors that accelerate the oxidation. Also, the extract of Hovenia dulcis Thunberg showed effects on the enzymes relating to the active oxygen toxicity which could be an indicator of aging and body toxicity.

김은호,이수진,Kim, Eun-Ho,Lee, Soo-Jin 한국군사과학기술학회 2009 한국군사과학기술학회지 Vol.12 No.3

Tactical Information Communication Network(TICN) uses both a wireless and wired network. To support mobility in battlefield environments, the application of Ad-hoc networking technology to its wireless communication has been examined. However, Ad-hoc network is faced to many security threats due to its intrinsic characteristics. Therefore, to apply the Ad-hoc networking technology to battlefield environments and TICN, an intensive study on security countermeasure must go side by side with the development of enabling technology. In this paper, we suggest an efficient key management scheme for TICN of which the Ad-hoc networking technology is applied.

This paper presents an analysis of multiple questions which occurred in Korean oral proficiency interviews. The data for the analysis of multiple questions come from a corpus of approximately two hours of Korean oral proficiency interview questions and tasks. Attention is placed on the sequential places of multiple questions with the goal of identifying functions of both vertical multiple questions, and horizontal multiple questions. Horizontal multiple questions are reveled to be placed delicate situation where the possibility of misunderstanding or mishearing may be high. In this case, to elicit an appropriate answer from the interviewee, the interviewer presents horizontally arranged subsequent question versions. Vertical multiple questions are in contrast revealed to be placed according to immediate interviewee's uptake.

The distribution and biomass of pelagicfish in centeral coast of west sea of Korea were studied by the scientific echo sounder from September 2006 to June 2007, every four season. The survey was performed by using 200kHz dual beam system, transmitter-receiver and indicator afterward recorded data was handled by using echo view software. The biomass was estimated using identification of object fish, acoustics data of volume backscattering coefficient(Sv), area backscattering coefficient(Sa), target strength(TS), and length and weight of target fish by sampling. Based on the survey line, divided the survey waters with 6 sections was 227.68km2. The area backscattering strength(SA) of each season indicated -62.0~-68.0dB in September(autumn), -63.0~-72.0dB in November(winter), -65.0~-71.0dB in March(spring) and -55.0~-66.0dB in June(summer). In addition, the mean target strength(TS) of many fishes distributed in the survey area in September, November, March and June was -57.0dB, -69.2dB, -69.1dB and -64.8dB, respectively. The catch rate by offshore stow net was occupied 98~99% of anchovy in september, 36~44% of akiami paste shrimp in november, 35~59% of akiami paste shrimp in march and 53~64% of southern rough shrimp, 13~14% of beka squid in june.

L2 speakers' use of Korean sentence-ending suffix-ketun

By using the methodological framework of conversation analysis, this study combines a grounded study of interactional linguistics focusing on L2 speakers' interactional competence in the use of Korean sentence-ending suffix -ketun. Based on the previous studies which examined the use of -ketun. in L1 Korean speakers' conversation, this study analyzes data taken from different levels of Korean language classroom interactions, with close attention to the learner's usage of the target suffix in formulating a dispreferred response. The findings of the study demonstrate that the L2 advanced students' use of -ketun is much closer to that for L1 speakers in constituting a dispreferred response while claiming epistemic primacy. On the other hand, extremely low frequency in the use of -ketun is a distinctive linguistic-pragmatic features that characterizes use of -ketun by L2 speakers at lower levels of competence. The advanced students' diversification may be an indicator of their more adaptive, con text- sensitive conduct, suggesting an increased interactional competence. Close scrutiny of the use of -ketun in this study aids to reveal whether and to what extent its interactional use by L2 speakers of different proficiency levels approaches that of L1 speakers.

한국어 교실에서의 수정적 피드백에 대한 대화 분석적 접근

김은호(Kim, Eun-ho) 중앙어문학회 2016 語文論集 Vol.65 No.-

본 연구는 대화 분석(conversation analysis, CA)의 질적 연구 방법을 한국어교실에서 나타나는 수정적 피드백(corrective feedback) 분석에 적용하여 외국어 및 제2언어로서의 한국어 학습에 있어서 기존의 형태 초점에 대한 논의를 재조명하는 것을 목적으로 한다. 비슷한 현상을 다루면서도 상반되는 접근법을 취하는 Long(1981, 1996)의 상호작용 가설(Interaction Hypothesis)에 바탕을 둔 수정적 피드백과 대화 분석(conversation analysis)에서의 수정(repair) 개념의 공통점 및 차이점을 살펴보고 두 접근법의 양립가능성을 실제 교실 대화 분석을 통해 알아본다. 구체적으로 학생의 오류에 대한 교사의 수정이 학생으로 하여금 실제로 형태에 초점을 두게 하는지를 교실 대화 자료를 통해 미시적으로 분석한다. 미국 한 대학의 한국어 중급 과정 교실 담화를 분석한 결과, 수정적 피드백의 종류 및 이에 대한 학생의 응답에 대한 양적 분포는 기존 선행 연구들의 결과와 큰 차이를 보이지 않았다. 그러나 질적 분석 결과, 교사의 수정적 피드백과 형태 초점의 관계를 양적으로 논의하는 기존 연구의 결과와는 다른 양상이 나타났다. 고쳐 말하기의 경우 이해 표시, 평가 등의 다른 행위에 삽입되어 수정의 기능이 진행 중인 다른 활동으로 인해 약화되거나 아예 드러나지 않음이 확인되었으며, 명시적 수정과 같이 교사가 직접적 수정을 제공하는 경우조차도 학생은 이를 다른 행위로 이해하고 형태에 집중하기 보다는 교실 과제 참여와 같은 다른 사회적 행위를 수행하는 것에 몰두하는 것을 볼 수 있었다. 이에 본 연구는 교사의 수정적 피드백과 그에 대한 학습자의 응답이 반드시 일관성 있게 나타나지 않으며, 교사가 학습자의 문법 형태에 대한 주의 집중을 목표로 수정적 피드백을 제공한다 할지라도 그것이 반드시 학습자의 형태 초점으로 이어지지는 않는다는 것을 주장한다. 본 연구의 결과는 형태 초점 및 외국어·제2 언어습득연구에 있어서 기존의 양적 접근법을 비판적으로 이해하고 대화 분석의 질적 접근법을 적용하여 형태 초점 연구에 새로운 시각을 제시할 수 있을 것으로 기대한다. Recent debates have addressed the complementarities between two lines of research concerned with corrective feedback in second language interactions: focus on form research and conversation analytic work on repair. This study investigates the teacher’s corrective feedback and students’ uptake in naturally occurring Korean L2 classroom interaction addressing the following research question: how is focus on form allocated among the participants and interactionally organized across the conversation? Focusing on episodes involving the type of corrective feedback that is most frequent in the current data set, the study shows that this question requires a detailed qualitative analysis of how participants orient to linguistic form on a moment-to-moment basis. The analysis reveals the analytic difficulty of determining exactly whose focus can be observed in focus on form extracts. There is no straightforward relation between the teacher’s corrective feedback and students’ attention toward form. Participants’ attention focuses shift frequently between dealing with linguistic forms, informational contents, organization of social actions, and the intersection between these factors.
