주구성 양이온이 Si와 Al인 딕카이트와 엽납석에 대하여 적외선분광분석(FTIR)을 실시하였다. 원적외선(Far-IR)영역과 중간적외선(Mid-IR)영역을 이용하였으며, 특히 200 cm-1 / 이하의 Far-IR영역에서 처음으로 딕카이트의 흡수선들을 제시하였다. 딕카이트의 경우 일부 시료에서 소량의 카올리나이트나 나크라이트 층이 소량으로 협재되어 있다. 카올리나이트의 결정도를 나타내는 Hinckley지수는 딕카이트의 결정도와는 관련성이 적게 나타났다. 엽납석의 경우, 수산기와 관련된 신축진동흡수띠(3673~3676 cm-1 )는 약간 이상적인 구조에서 벗어나 있는데, 아마도 미량의 철에 의한 영향이나, 삼사형과 단사형이 섞여 있기 때문인 것으로 보인다.

It is being more and more difficult to suppress emissions from electronic products using PCB(Printed Circuit Board) to the limit. Therefore, the exact evaluation of the emission from PCB has been more important to reduce the required time and the cost at the design phase of the products, especially on board ship's equipments. This research has evaluated the emission radiated from PCB based on the theoretical approach of SDA(Spectral Domain Analysis), which is available to analyze microwave stripline, coplanar line, patch antenna, etc. According to the theoretical results, it has been clearly shown that the emission radiated from PCB is reduced as the thickness of PCB is thinner, the permittivity of PCB is higher, the length of stripline is shorter, and the frequency is lower.

인공배수 되고 있는 농업유역을 위한 확장된 TOPMODEL은 강우유출 모의를 위해 개발되어졌다. 불포화흐름의 해석을 위해 기존 모형의 저류함수법과 본 연구에서 새로이 제시하는 전달함수법을 비교하였다. 매개변수의 민감도 결정과 저류함수법과 전달함수법간의 거동의 비교를 위하여 영역화 민감도 분석기법이 쓰였다. Monte-Carlo 방법을 활용한 변수 추정시, 전달함수를 활용한 모의가 보다 많은 성공적인 모의결과의 변수조합이 관찰되었다. 강우유출 양상의 계절

The defects occurred in knitted fabrics have several types due to some trouble sources. In particular, the defects caused by knitting machine troubles give a serious damage to the whole webs. It is, therefore, necessary to discriminate the kind of defects. The method to discriminate the type and size of defects has been proposed, which is used a pair of narrow band eliminating spatial filters. This method is based upon an isotropic signal processing in time domain. This paper is to confirm that the proposed method can be useful in the discrimination of defects, having analyzed in spatial frequency domain.

Two experiments were conducted to evaluate breathing zone air quality in Taegu, using automatic analyzers for four air quality standards(SO2, NO2, CO, and O3). First, air target compounds were measured for 8 to 12 hours in each of two commercial areas and five residential areas. Second, air target compounds were hourly measured for 24 hours in each of two commercial areas, two residential areas, and an industrial complex area. Based on the first experiment the breathing zone air was more polluted in the commercial area as compared to the residential area, while the second experiment showed that the breathing zone air was polluted rather in the residential area as compared to the commercial area. The second experiment also indicated that there was some variation of breathing zone air concentration with time and measuring sites. Diurnal variation of breathing zone air concentrations was consistent with previous studies which measured at building height. The highest breathing zone air concentration was shown in Seongseo industrial complex area. An unusual finding of this study was that SO2 concentration in the breathing zone air of Bisandong, a typical residential area of Taegu, was higher than that of other residential areas, even higher than that of Seongseo industrial complex area.

The characteristcs of children`s motor performance are slow response, low accuracy, greater var iability, inappropriate response, and ignoring KR when they perform at will. Not only physical growth, development, and maturation but also information processing capacity results in children`s motor performance deficits. In the late 1970s, motor development theorists accepted information processing model to explain the motor performance differences between adults and children. they try to clarify that whether the performance differences are due to structure(capacity) or function (control process) . To date, many researches show that the performance differnces result from children`s lack of control process rather than children`s small capacity. Children do not know how to lable the incoming information, how to rehearse to memorize the information in the long-term store, and how to organize the information already existed in their memory effectively, However, if children have enough information about specific task, they spontaneously develop adult-like memory strategy. This facts are due to their great knowledge base. Therefore, even though their sophisticated memory strategy can not compensate all their motor deficits, the role of teachers and coaches is to give children various movement experiences making their knowledge base bigger.Attribution theorists conceptualize causal ascription, the perceived causes of previous performance, as a major sources of achievement motivation. Therefore, they focus their interest on searching for the causes of events. For any given situation, however, their may be an infinite number of potential reasons why a particular event ocurrs. Many attribution theorists nowadays generally clasify these causes along three causal dimensions (internality, stability, and controllability) . They believe that individuals understand the causes and give meaning them on the basis of these dimensions. Attribution theory deals with two main areas : antecedents of attribution and the consequences of attribution. In sport-related areas, win or lose-attribution link has been the most studied of the two. In order to be a firmly established theory and to be utilized in achievement situation, further research in attribution framework is required in attribution. consequence link and in antecedent-attribution link also in addition to win or lose-antecedent link.

제5차 국어과 교육과정은 본래 논리적인 체계보다 심리적 원리를 바탕으로 설계되었으며 실생활에서 전이가를 높이기 위해 학습자의 일상 생활에서 학습활동의 소재를 취한 것들이 많아서 논리적으로 만족할 만한 체계화를 기하기에는 어렵게 되어 있다. 그러나 본 고에서 시도한 바와 같이, 제한된 부분에서나마 유사한 지도내용끼리 관련을 짓고 학년을 달리하여 심화 확장되어가는 모습으 추적하여 체계화하는 작업은 미흡한대로 다음 세 가지의 의의를 지니고 있다고 본다.
