Recently, Most enterprises produced ready mixed concrete uses a mixing water as a recycling water without a density control in proportion to guide and standard. That is a cause of deterioration in the concrete quality like a reduce of strength, laitance, crack, etc. This study shows basic materials for development of ready mixed concrete recycling water density control system that holds down a deterioration in the concrete quality by using a mixed water treated recycling water with stabilizing agent and examines a possibility of re-using components of cement in recycling water. Therefore, in the experiment, we make a recycling water contains 3,5,7% of solid content ratio examines a property of a mixing water with a stabilizing agent and without it. Results of this study is next as follow. 1. The slump is decreased 1~2cm in a mixing without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 2. The air content is 4~4.7% in proportion to an increase of solid content without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 3. The compressive strength of an early curing age is tendency to increase both the mixing without a stabilizing agent and the mixing with a stabilizing agent. But, After 14days is passed, Compressive strength is decreased in a mixing without a stabilizing agent but increased a mixing with a stabilizing agent.

세계화시대와 가정학 연구 : Human Ecology-Based Researches in Korea Facing Global Promotion

박영숙,최혜선,윤인경,이승신,이주리 대한가정학회 2004 Family and Environment Research Vol.42 No.2

Human Ecology researches studying human life patterns in Korea are on the same tracts of recent global promotion in Korea as that of other academic studies. In this changing academic atmosphere, Human Ecology-based researches are in demands of suitable research topics and methods. This study was done to investigate the present research situations of Human Ecology-based subdivisional fields, including food and nutrition, clothing and textiles, child studies, family studies, home management, housing studies, consumer sciences and home economics education, by an increasing need in the society of KHEA (Korean Home Economics Association). The study focused on understanding the trends of research topics and methods shown in the papers published in major academic periodicals in Korea as well as world-class (XI, SSCI) journals in order to predict the future for Ecology-based studies in Korea. The data were collected from all periodicals from January, 2000 to August, 2003, listed in the Korean Research Foundation and from world-class journals comparable to the former. Twenty-six periodicals were chosen for analysis, including papers with authors of ecology-based, field faculty at colleges or universities. There were some differences between the Korean and world-class research topics and methods. In order to narrow the gap between the two, we suggested that serious consideration be given to the research's application-ability toward human beings, which would be the homeecology study's identity. The same criteria in these fields as used in other natural science fields are not suitable for supporting and evaluating research proposals and outputs, and recent global academic promotions may not be desirable in some respects. However, they do present an opportunity to expose Korean researcher's to world-class scientific societies and upgrade their studies. These efforts should stimulate the field of Human-Ecology studies and enhance the recognitions of these fields among future students

We should maintain the maximum operation capacity for production facilities and find properly out the fault of each equipment rapidly in order to decrease a loss caused by its failure. The acoustic signals of a machine always carry the dynamic information of the machine. These signals are very useful for the feature extraction and fault diagnosis. We performed a fundamental study which develops a system of fault diagnosis for a pump. We obtained noises by a microphone, analysed and compared the signals converted to frequency range for normal products, artificially deformed products. We tried to search a change of noise signals according to machine malfunctions and analyse the type of deformation or failure. The results showed that acoustic signals as well as vibration signals can be used as a simple method for a detection of machine malfunction or fault diagnosis.

이동물체의 기하학적 특성에 기인한 움직임 정보 추출

박인전,오미숙,백경주,정영철,김신규,박종안 조선대학교 전자정보통신연구소 2002 電子情報通信硏究所論文誌 Vol.5 No.1

In this paper, we have proposed an effective moving objects tracking method based on the motion information in the video sequence. First, we extract the moving objects using the processes of morphological dilation and differential image in the video sequence and then we extract the motion information utilizing the location and orientation of the moving objects in the subsequent images. The motion information is extracted using various statistical measurements, extracting the high-level features from the regions of pixels in the images. The measurements, such a s area, length, perimeter, orientation, elongation, compactness, moments of inertia, are used as the statistical and geometrical descriptors. The principle axes of an object on this features gives the local direction of the object, while the center of gravity gives the center position of the object. The angle between two principal axes of the moving objects in the consecutive images gives the geometrical direction of the moving object, while the displacement of the center of gravity, gives the distance covered by the moving objects. So we have extracted the global motion information using the principal axes and center of gravity. The simulation results on the test images are very good, where either the motion is very slow, or the frame rate is very high.

「カリ」活用の品詞に關する諸說

박영신 상명대학교 어문학연구소 2000 語文學硏究 Vol.9 No.-

본 연구의 주지인 カリ활용은, 형용사의 連用形에 ラ變動詞アリ가 융합해서 형성된 활용형식이다. ラ變動詞는 존재의 의미를 나타내는 동사로, 대단히 형용사에 가까운 語性을 갖는다. 따라서 アリ의 품사자체가 江戶중기부터 말기에 걸쳐서 「동사다」「형용사다」라는 문제로 되어왔던 것이, 江戶末期의 부견광음에 의해서 變格動詞로 되고, 그 이래 동사로서의 위치를 확립했다. 그런데 이 동사アリ에는 순수하게 존재의 의미를 나타내는 것과, 진술의 작용에 관여하는 것이 있다. 富士谷成章は 前者를 「孔」(ありな)로 부르고, 後者를 脚結アリ로 구별했다. 그리고 명치이후의 문법론에서는, 각문법가의 用言觀이나 詞辭論에 의해서, 이것을 어디까지나 「詞」로 보는 입장과 「辭」라고 주장하는 의견이 대립하고 있다. 그리고 이 문제는 동사의 범위를 넘어서, ラ變動詞アリ가 개입하고 있는 조동사는 물론이고, 외국에는 없는 形容動詞라고 하는 품사의 존재여부를 둘러싼 논쟁을 일으켰다. 그 결과, 形容動詞를 인정하는 說과 부정하는 說이 출현해서, 지금도 그대로이다. 그러나 학교문법에서는 橋本進吉박사의 補助動詞アリ說이 채용되고 있기 때문에, 모든 문법이론도 이것을 기준으로 하고 있다. 그러나 문법가의 지론을 분석해보고 얻을 수 있는 결론은, 吉澤義則박사의 「形容動詞カリ活用」說의 재음미가 필요하지 않을까하는 점이였다. 즉, 소위 ナリ·タリ활용을 形容動詞로 인정하는 근거가 「어간+ニ/ト+アリ」(カリ活用)도 形容動詞로써 인정해서 좋은 것은 아닐까 생각된다. 吉澤박사는 カリ활용을 第一種形容動詞, ナリ활용을 第二種, タリ활용을 第三種形容動詞로 했다. 그러나 학교문법으로써 채용된 橋本說의 주안은 형용사의 어간의 형용성에 있고,「∼くあり>かり」는 형용사와 조동사를 연결하는 기능을 하고 있을 뿐이므로, カリ활용은 형용사의 활용형식의 일종, 즉 補助活用이라고 했다. 외견상은 그대로이다. 그러나 형용사의 본 기능이란 무언가를 형용하는 점에 있지, 진술이나 판단성이 아니라고 생각된다. 조동사가 필요한 문장이란 이미 형용사가 단지 피수식체를 수식하는 기능이상의 것으로 탈피하는 것을 요구하고 있다. 이 점에 있어서 형용사와 조동사의 사이에 形狀言적 성격이 농후한 アリ가 개입한다고 하는 것은, 순수한 형용사에 동사성분이 첨가된 것, 즉 形容動詞로 보아야만하지 않을까 생각된다. 금후의 연구과제로써 일본 본토어의 형용사 シ어미와, 친족관계가 인정되고 있는 유일한 방언인 流球방언에 있어서의 형용사 조어법 「高さ·あり>高さり」와 「高く·あり>高かり」의 어법상의 차이점에 대해서 연구하고싶다. 「高さり」의 쪽은 「高さ(が)あり」로 일본본토어의 「高し」에 대응하고, 「高かり」의 쪽은 「高く思われる/見える」로 통한다고 생각되어지기 때문이다.

본 연구는 간접 복합레진 수복물을 1종의 자가부식형 레진시멘트와 3종의 자가접착형 레진시멘트를 이용하여 상아질에 합착하였을 때 각 레진시멘트의 미세인장 결합강도와 결합계면의 차이를 평가하기 위하여 시행하였다. 발거된 상.하악 대구치 교합면 측 상아질에 Tescera 복합레진 블록을 레진시멘트(PA 군: Panavia F 2.0, RE 군: RelyX Unicem Clicker, MA 군: Maxem, BI 군: BisCem)를 이용하여 합착하였다. 증류수에 24시간 동안 보관한 후, 합착된 면의 단면적이 1.0 × 1.0 mm인 막대모양의 시편을 제작하여 각 시편에 분당 0.5 mm의 crosshead speed로 인장하중을 가하였다. 각 군의 미세인장 결합강도는 one-way ANOVA와 Tukey의 HSD 방법을 이용하여 비교하였다. FE-SEM 하에서 모든 파절편의 상아질 쪽 파절양상과 레진시멘트-상아질 및 레진시멘트-복합레진의 계면을 관찰하였다. 본 연구의 결과 간접 복합레진 블록을 레진시멘트로 상아질에 합착할 때 PA 군과 RE 군은 MA 군과 BI 군보다 높은 결합강도와 긴밀한 접착 및 레진테그가 관찰되었고, 복합레진과 레진시멘트 간에는 간극이 관찰되었다. The purpose of this study was to evaluate the microtensile bond strength (μTBS), failure modes and bonding interfaces of self-etching and three self-adhesive resin cements to dentin and indirect composite resin. Cylindrical composite blocks (Tescera, Bisco Inc.) were luted with resin cements (PA: Panavia F 2.0, Kuraray Medical Inc., RE: RelyX Unicem Clicker, 3M ESPE., MA: Maxem, Kerr Co., BI: BisCem, Bisco Inc.) on the prepared occlusal dentin surfaces of 20 extracted molars. After storage in distilled water for 24h, 1.0 mm × 1.0 mm composite-dentin beams were prepared. μTBS was tested at a cross-head speed of 0.5 mm/min. Data were analyzed with one-way ANOVA and Tukey’s HSD test. Dentin sides of all fractured specimens and interfaces of resin cements-dentin or resin cements-composite were examined at FESEM(Field Emission-Scanning Electron Microscope). In conclusion, PA and RE showed higher bond strength and closer adaptation than MA and BI when indirect composite blocks were luted to dentin using a self-etching and three self-adhesive resin cements.
