A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

Lee, Tack,Lim, U-Sung,Kang, Dong Hyuk,Jung, Hae-Do,Kim, Hyunzu,Choi, Bo-Hwa,Kang, Ju-Hee,Yoon, Sang-Min,Park, Chang-Shin Korean Continence Society 2017 International Neurourology Journal Vol.21 No.4

<P><B>Purpose</B></P><P>The pathophysiological role of detrusor overactivity (DO) in the bladder, which is commonly observed in various bladder diseases, is not well understood. DO appears in bladder outlet obstruction (BOO), and may continue even after subsequent deobstruction. DO therefore provides an excellent opportunity to observe molecular biological changes.</P><P><B>Methods</B></P><P>In this study, to understand the molecular effects of persistent DO after BOO induction and deobstruction, we performed awake cystometry on female Sprague-Dawley rats divided into 4 groups: a sham group, a BOO group, a deobstructed group with DO after BOO (DDO), and a deobstructed group without DO after BOO (non-DDO). Total RNA was extracted from the bladder samples, and gene expression profiles were compared between the sham and model groups.</P><P><B>Results</B></P><P>DO was observed in 5 of the 6 rats (83%) in the BOO group, and in 6 of the 13 rats (46%) in the deobstructed group. The non-DDO group showed a significantly greater residual volume than the DDO group. Through a clustering analysis of gene expression profiles, we identified 7,532 common upregulated and downregulated genes, the expression of which changed by more than 2 fold. In the BOO group, 898 upregulated and 2,911 downregulated genes were identified. The non-DDO group showed 3,472 upregulated and 4,025 downregulated genes, whereas in the DDO group, only 145 and 72 genes were upregulated and downregulated, respectively.</P><P><B>Conclusions</B></P><P>Abnormal function and gene expression profiles in bladders after BOO were normalized in the BOO rats with DO after deobstruction, whereas in those without DO, abnormal function persisted and the gene expression profile became more abnormal. DO may play a protective role against the stress to the bladder induced by BOO and deobstruction as a form of adaptive neuroplasticity.</P>

This study covers amenity analysis of the subway 1st line and improvements focusing on the easiness, amenity, safeties, and elements of amenity. When people come to the entrance of a subway station, they pay careful attention to easiness of use, amenity and locality of the area. Therefore, by getting rid of unnecessary stairways, we can minimize the economical loss secure the easiness of use and stability. At the same time, well designed planters and trees dedicated to boulevards which can increase the ratio of green space. Furthermore, each gate of subway stations should have the identity of the area. Finally, we suggest those facts which are mentioned above should not be repeated that when designing the Pusan subway line 2nd line which is under construction.

This research has done in this summer and on October we finished it. The purpose of this study really is to know the marks of people's ideas in Gindo. As the principal means of it we made use of the the question-naire which is generally used to investigate the social affairs, and then we referred to the special reports on the rural society. We stret-ched the boundary of this investigation over all area in Gindo. On account of the good environment nearly all of the residents have a good temper and have lived for ten years over, but in history they have gone through a number of historical ordeals. Generally speaking they mostly have engaged in agriculture, but they all are the peasants. Therefore nearly all of people im Gind? have a tendency of the statical thought. I. The family relations and moral senses. We can see the facts that their senses changed the traditional large family into the modern family. Therefore the filial duty was dissolved gradually, and so they changed little by little the vertical relations into the horizontal relations. But yet the moral senses which originated in confucious are vivid in them. II. Social senses. They increase gradually in the participation in social affairs. Although they have few of the real voluntary groups, they have many social small groups (ex. Dure) in which many of the residents have partaken. III. Economic senses They have the traditional senses of economy, and so their senses show a slight increase in the profit motive which has constructed the flourishing Capitalism in West-Europe. On the other hand 'Sal-ma-eul campaign' which aims for the modernization of our country goes on with activity. And it stirs them to self-reliance, therefore it makes them get the cooperative motive. IV. Political senses. Since the liberation of our country, the democracy which imported from the western world had wrongly known to them. But today they are gradually getting the political senses which are grounded in our reality. But they fainted in political interest, because they concentrate earnestly on the realistic economic affairs. As a conclusion, we can tell you that the traditional marks of people's senses in Gindo are slowly transformed into the modern trends which show the dynamic senses and the rational thought. But they are yet interested in the traditional morals. This indicates that they don't like the mammonism and the matterial civilization which are imported from the West.

김도권,이상한,조만희,김창세 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.1

The menasurements of pesticide carbaryl were studied, and the following conditions were proposed as a most good method; 1. These were detected at 222 nm by means of ISCO model 2350. 2. Pesticide carbaryl measurement was performed by means of ISCO model 2350, Spherisorb ODS column, 40% acetonitrile as a solvent, flow rate 1.0 ml/min, and chart speed 0.5 cm/min. 3. The relationships between the concentration and the absorbance of pesticide carbaryl were linear from 0.5 to 5 ppM. 4. Deproteinzation would be used satisfactorily in all of Folin-Wu, trichloractic acid and perchloric acid, and the recovery rate was also satisfactorily for all of them.

前置詞의 構造와 構文上의 位置

李昌希,李容晟,金龍度 부산외국어대학 1984 논문집 Vol.2 No.-

本 論文에서는 前置詞와 名詞句의 結合 인 前置詞句에 對하여 硏究해 보았다. 우선, Jackendoff의 X Convention에 따라 前置詞句의 內的 構造를 Specifier-Preposition Complement로 보고 各各의 特徵을 찾아 보았다. 나아가서 表面上으로는 前置詞句와 類以한 連結 를 지니고 있으나 意味的 構文的으로 전혀 다른 屬性을 지닌 結合 가 있음을 確認하고 이것과 前置詞句의 差異를 例文을 通하여 分析, 檢討하여 보았다. 더불어 同一한 前置詞句라 할지라도 点有하는 構文上의 位置에 따라 意味解釋에 重大한 影響을 미치며 또 外面上으로는 類似하더라도 그 位置가 深層 構造에서는 判異하게 다름을 이 分析을 通하여 發見할 수 있었다. 이제까지 文法 硏究에 主要 對象이 되지 못하였던 前置詞句를 다시 한번 照査해 보고 그 構造上의 特質을 發見함으로써 本 論文이 前置詞句의 重要性을 認識시키는 契機가 될 수 있기를 바란다.
