Recently, many people have become interested in seismic stability enhancement and a chain of research and development be proceed for application of nuclear power plant according to increase the frequency and magnitude of earthquake event. Such as seismic isolation system is applied to general structure (architecture, bridge and LNG tank etc.) from ancient times. But the application results is limited for Nuclear power plant. In this paper, we proposed a stability of variable axial load from beyond design basis earthquake in Nuclear power plant. Also, the change of stiffness in isolator from the application of generally design equation is not equal to according to change in axial load compare with the experimental result in variable axial load. Therefore we proposed the empirical formula of design equation from test result of full-scale multi-lead rubber bearing for seismic analysis with real behavior (variable axial load) in the earthquake motion.

初對面雜談における連鎖構造分析の一考察 -意見/評價提示からはじまる連鎖構造を中心に-

장양광 ( Chang Yang-kwang ) 한국일어교육학회 2016 일본어교육연구 Vol.0 No.36

本硏究は、雜談を課題遂行性の低い會話形式として捉え、會話の規範や規則を明らかにするため、發話の連鎖構造を分析した。方法としては、發話ひとつひとつを重ねていき、それを連鎖構造とし、これを話題と反定した。そして、會話參加者の一方が情報の所有者である場合は、情報要求ではじまるものと、情報提供ではじまるものに分類した。また、自己開示を「相手の情報を收集する方法の一つとして、自ら自分自身について相手に話すこと」とし、情報提供からはじまるものを自己開示からはじまる連鎖構造とした。自分自身の情報を利用し、自己開示からはじまる連鎖構造を<意見/評價提示>と<部分的報告>に分類し、このうち<意見/評價提示>からはじまる連鎖構造を中心に分析を行った。その結果、意見/評價提示のあとに同意表明が非常に高い割合で現れ、同意表明をおこなった後は、意見の根據說明が相互になされることがわかった。一方、不同意を表明する場合、聞き手の不同意表明後、意見/評價の訂正が行われ、雙方から意見の根據說明がなされることがわかった。同意表明の言語形式としては、意見提示において、意見提示へのためらいを表すような「なんか」が文頭や文末へ、斷定を避ける「~けど」や、同意を求める「~よね」が文末へ表れる傾向があった。一方、不同意表明の言語形式としては、意見提示において意見提示へのためらいを表すように節末の音を伸ばしたり、斷定を避ける「~けど」が表れる傾向があった。不同意表明では「でも」が表れる傾向があり、意見/評價訂正では、「なるほど」という理解を示すものと文末表現「~ね」が見られた。 This study considers small talk as a sort of communication. To discover small talk’s norms and rules, utterance sequence organization was established to analyze through utterance sequence pattern. This research defined general conversation’s rules and regulations to be like other types of conversation. In the results of the analysis of the first utterance, 62.9% of conversations started from questions, 29.03% of conversations started from opinions, 7.74% started from the sharing of common sense, and 0.32% began from other first utterances. As a result, appeared at a high proportion of consent expressed after the opinion / evaluation, after you made the agreement announced, it was found that the grounds description of the opinion will be made to each other. On the other hand, in the case of disagreement expressed, after the announcement of the disagreement of the listener, the correction of opinion / evaluation was done. And it was found that grounds explaining views from both is made.

初対面の雑談における連鎖構造分析

張良光(Chang, Yang-Kwang) 한국일본문화학회 2016 日本文化學報 Vol.0 No.69

This study considers small talk as a sort of communication. To discover small talk’s norms and rules, the organization of utterance sequences were established to analyze utterance sequence patterns. As a result, when a listener shows understanding/, evaluation/, or sympathy toward a speaker’s provision of information, a speaker tends to give detailed information and helps the listener understand. Next, as a consequence of analyzing sequence organizations with implanted sequence confirmation, a listener tends to show sequence confirmation to reduce unclearness that comes from a speaker’s uncertain provision of information. When the analysis of sequence organization provides information of switching roles of a listener and speaker, the tendency, to which a speaker talks about recent stuff while a listener sympathizes and provides back information with the listener’s own recent small talk, was discovered. Finally, as a result of analyzing about language form, there are numbers of hedges to describe a speaker’s ambiguousness in utterance of provision of information.

初對面雜談における連鎖組織の一考察 -話題の對象を中心に-

장양광 ( Yang Kwang Chang ) 한국일본어교육학회 2015 日本語敎育 Vol.0 No.72

In this research, a topic of first time meeting conversation to make a new human relationship is analysed. Basically, the topic of sequence organization is analysed and break sequence organization down into patterns. The result of analysis in 10 conversation data, about 63 percents of sequence organizations are started from questions; about 29 percents of sequence organizations are started from opinion and about 8 percents of sequence organizations are started from sharing common elements. Moreover, some tendencies are found in this research when considering about target topic. For example, research participants who started sequence organizations with question were more likely to talk about other research participant. Research participants who started sequence organizations with opinion were more likely talked about related participants’ event and/or thought. Research participants who started sequence organizations with sharing common elements are were likely talked about related participants’ thought.

Background: In order to induce primary care physicians (PCPs) to practice guideline-based treatment, various supplementary tools have been developed, but its effect on the change of actual prescription practice is still unsatis factory. Objective: This study was conducted to investigate and Easy Asthma Management (EAM) program helps PCPs to prescribe medications based on the guidelines. Method: Requested cases for health insurance review by physicians were analyzed. A Total of 542 cases were compared between the changes before and after the training, and they were also compared with 374 requested cases by the control group. Result: After the training, changes asthma medication prescription were observed as follows: in the trained physician group 24% reduction in beta2-agonists; 24% reduction in methylzanthines, and 16% increase in steroids, in case of steroids, 46% reduction in oral steroids only; 64% increase in inhaled steroids with beta2-agonists; in the control group, 4% increase in beta2-agonists, 3% increase in methylzanthines, and 3% reduction in steroids after the training. Conclusion: In this study, physicians who received EAM training program showed the changes of prescription according to guideline-based anti-inflammation prescription, compared with non-trained physicians.

정수장 유입조류 전처리를 위한 천연조류제거제(W.H.)의 최적주입농도 결정

하천과 호수의 부영양화로 인하여 남조류가 대량으로 증식하게 되면 고유의 생물독소로 인한 위해뿐만 아니라 정수처리 과정에서 경제적 손실을 야기할 가능성이 있다. 현재 상용화되어있는 천연조류제거제인 M사의 W.H. 응집제(이하 W.H.)는 참나무 유래 성분의 살조 및 타감작용을 이용한 응집․부상공정을 통하여 조류를 사전에 제거함으로써 정수공정에 미치는 영향을 효과적으로 저감할 수 있다. 그러나, W.H.를 활용한 응집․부상공정은 정수처리의 전처리공정으로 적용된 사례가 없기 때문에 최적주입농도의 결정기법에 대한 보고 또한 전무한 실정이다. 본 연구에서는 ① 한강에서 채취한 복합 조류와 ② 남조류를 선택적으로 대량 배양하여 광조건 하에서 W.H. 투여량 및 조류농도 등의 여러 조건을 변화시키면서 Jar-test를 시행하여 응집·부상공정에서의 조류의 제거기작을 검토하였다. Jar-test 결과를 바탕으로 IBM-SPSS를 활용한 다중회귀분석을 실시하여 최적 W.H. 주입농도를 결정하기 위한 Chl-a 농도와 탁도를 변수로 하는 두 가지 선형식을 도출하였다. 또한 유입수질의 변동에 따라 W.H. 주입농도를 신속하게 결정하고 자동화할 수 있는 자동제어 로직의 프로토타입(Prototype)을 제시하였다. Algal blooms of cyanobacteria (blue-green Algae) due to the eutrophication of rivers and lakes can cause not only the damage by its biological toxins but also the economic loss in drinking water treatment. The natural algae coagulant, a commercial product known as W.H. containing the algicidal and allelopathic material derived from oak, can control algal problems proactively through the coagulation・flotation process. However, because there have been no applications of the process for pre-treatment in drinking water plants, we could find no report on the optimum injection dose of W.H.. In this study, we have conducted several sets of jar-tests while changing W.H. dose and concentration of chl-a for ① Han-river samples and ② subcultured cyanobacteria samples, and monitored the removal mechanisms of algae intensively. Based on these jar-test results, two linear equations with variables of chl-a and turbidity have been deduced to predict the optimal W.H. dose after the multiple regression analysis using IBM-SPSS. Also, prototypes of automatic control logic have been suggested to inject the optimal W.H. dose promptly in response to the variation of water quality.
