Visual MODFLOW, a three dimensional groundwater flow model, was used to analyze effects of a weir construction in an alluvial stream on the nearby groundwater flow system. A hypothetical conceptual model was developed to investigate how the groundwater level and the water budget could change after a weir construction depending on the location of tributary streams. A site example, dealing with the Juksan weir installed in the Yeongsan River, was also demonstrated to predict the effects of the weir construction. Model results show that impacts of a weir construction on the groundwater flow system greatly vary depending on how far a tributary is located and whether it is located downstream or upstream from the weir. Therefore, consideration of the location of tributaries in planning the location of a weir could effectively minimize the impacts of a weir construction on the groundwater flow system. It is also demonstrated that model results are highly dependent upon how the model is dealing with small tributaries and agricultural drainage channels, which can be easily found nearby the main streams, acting as major water bodies for groundwater discharge. The model for the Juksan area shows that the weir construction will change the direction of groundwater flow in some areas, leading to changes of groundwater quality and interaction of the Yeongsan River to the aquifer from a gaining to a losing stream. The model also predicted the areas where rise of groundwater level caused by the Juksan weir could adversely affect plant growth, and thereby suggested installing new drainage channels as a countermeasure to drawdown the groundwater level.

In commercial solar cells, the pattern of the front electrode is critical to effectively assemble the photo generated current. The power loss in solar cells caused by the front electrode was categorized as four types. First, losses due to the metallic resistance of the electrode. Second, losses due to the contact resistance of the electrode and emitter. Third, losses due to the emitter resistance when current flows through the emitter. Fourth, losses due to the shading effect of the front metal electrode, which has a high reflectance. In this paper, optimizing the number of finger on a $4{\times}4$ solar cell is demonstrated with known theory. We compared the short circuit current density and fill factor to evaluate the power loss from the front metal contact calculation result. By experiment, the short circuit current density($J_{sc}$), taken in each pattern as 37.61, 37.53, and $37.38mA/cm^2$ decreased as the number of fingers increased. The fill factor(FF), measured in each pattern as 0.7745, 0.7782 and 0.7843 increased as number of fingers increased. The results suggested that the efficiency(Eff) was measured in each pattern as 17.51, 17.81, and 17.84 %. Throughout this study, the short-circuit current densities($J_{sc}$) and fill factor(FF) varied according to the number of fingers in the front metal pattern. The effects on the efficiency of the two factors were also investigated.

With the increase in installed solar energy capacity, comparison and analysis of the physical property values of solar cells are becoming increasingly important for production. Therefore, research on determining the physical characteristic values of solar cells is being actively pursued. In this study, a diode equation, which is commonly used to describe the I-V behavior and determine the electrical characteristic values of solar cells, was applied. Using this method, it is possible to determine the diode ideality factor (n) and series resistance ($R_s$) based on light I-V measurements. Thus, using a commercial screen-printed solar cell and an interdigitated back-contact solar cell, we determined the ideality factor (n) and series resistance ($R_s$) with a modified diode equation method for the light I-V curves. We also used the sun-shade method to determine the ideality factor (n) and series resistance ($R_s$) of the samples. The values determined using the two methods were similar. However, given the error in the sun-shade method, the diode equation is considered more useful than the sun-shade method for analyzing the electrical characteristics because it determines the ideality factor (n) and series resistance ($R_s$) based on the light I-V curves.

정수정,임걸,고유정,심현애,김경연,Jeong, Su-Jeong,Lim, Keol,Ko, Yu-Jung,Sim, Hyun-Ae,Kim, Kyung-Yeon 한국디지털콘텐츠학회 2010 한국디지털콘텐츠학회논문지 Vol.11 No.2

본 연구는 현재 공급되고 있는 교육용 어플리케이션에 다양한 기준을 적용하여 분석하고, 온라인 또는 원격교육의 특성이 어떻게 적용될 수 있는지에 대한 가능성을 모색하였다. 이를 위해 총 85개의 교육용 어플리케이션을 선정하였고, 콘텐츠 유형, 상호작용 유형, 콘텐츠 유형과 상호작용 유형의 조합을 준거로 분석하였다. 분석결과 콘텐츠 유형에서 반복연습형 및 도구형 등 빈도는 높은 반면, 모의실험과 문제해결형의 빈도는 낮았다. 상호작용에 있어서는 학습자와 콘텐츠 간 상호작용 유형이 대부분을 차지하였는데, 따라서 원활한 학습자간 의사소통의 확장이 이루어지는데 한계가 있었다. 따라서 SNS(Social Network Service) 어플리케이션 등의 특징을 적용하여 학습의 상호작용성을 촉진시키기 위한 목적으로 교육용 어플리케이션이 개발될 필요성이 있음이 발견되었다. 아울러 본 연구 결과를 바탕으로 스마트폰의 교육적 활용에 관한 몇 가지 제언을 하였다. This study analyzed educational applications in smartphones with some criteria seeking to apply online learning characteristics to smartphones. For the analysis, 85 educational applications were selected and they were classified by types of educational contents, interactions, and the combination of the educational contents and interactions. As a result, drill-and-practice and tool types of contents ranked high, and there found to be few simulation and problem solving types. In regard to interaction types, almost all of the applications had interactions only between contents and learners, which meant little active communications when using applications. Therefore, enhanced interactions and communications among learners using the social network service platform were required in order to use educational applications in a more effective way.

광고전략으로서 속담의 사용에 관한 연구 - 독일 지면광고를 중심으로

In diesem Beitrag wird versucht, zu untersuchen, wie die Sprichwörter in deutschen Anzeigen zur effektiven Vermittlung vom Wissen sowie zur Erregung der Aufmerkasamkeit beitragen. Vor allem konzentriert sich der Fokus darauf, in welchem Zusammenhang dabei die semantisch-pragmatischen texuellen Wirkungen von Sprichwöretrn mit Werbungsstrategien stehen. Ziele der Anzeigewerbungen bestehen heutzutage nicht lediglich darin, den Verkauf von Waren und Dienstleistungen zu fördern sowie das Image der Firmen aufzubauen, sondern die Anzeigen als Spiel und schöpferische Tätigkeit bewegen den Konsumenten auch, die Werbebotschaft akiv, kreativ zu gestalten und zu rekonstruieren. Sprichwörter werden in der Werbung oft förmlich sowie semantisch variiert verwendet, wobei sich Werbungkonsumenten an das ursprungliche Sprichwort erinneren und seine Informationen aus dem Langzeitspeicher aktualisieren. Abgewandelte Sprichwörter bringen offenbar dazu, dass sich Werbung skonsumenten aktiv, kreativ an ihrer Interpretation beteiligen sollen. Trotz unausreichend semantischer Realisation der Schlagzeile wären Konsumenten durch die Erinnerung an Informationen aus dem Langzeit-Gedächtnis in der Lage, die Anzeigen sinngemäß zu interpretieren. Außerdem stellen Sprichwörter eine der zur Werbung geeigneten Sprachmitteln dar, da sie aufgrund ihres großen Bekanntheitsgrades zur Verarbeitung durch Konsumenten relativ kurze Zeit benötigen.

관용구에 나타나는 오스트리아독어 변이형에 대한 고찰

정수정 ( Su Jeong Jeong ) 한국독일어문학회 2015 독일어문학 Vol.69 No.-

In diesem Beitrag wird versucht, zu untersuchen, was fur Varianten es zwischen der osterreichischen und der binnendeutschen Varietat auf der Ebene der Phraseologismen gibt. Dabei liegt das Hauptaugenmerk darauf, herauszufinden, wie sich die Besonderheiten des osterreichischen Deutsch auf die Phraseologismen ubertragen. Es stellt sich heraus, dass osterreichisches Deutsch und Binnendeutsch Unterschiede auf Ebene der Phonetik, Phonologie, Wortbildung, Morphosyntax und Lexikologie sowie Pragmatik aufweisen und daruberhinaus auch die Differenzen in der Rechtschreibung und der Bedeutung bestehen. Die Phraseologie weist, gleich wie andere Disziplinen, auch Abweichungen auf. Osterreichspezifische Phraseologismen mit binnendeutscher Aquivalenz werden gemaß den sprachwissenschaftlichen Teildisziplinen klassifiziert. So treten Differenzen zwischen der binnendeutschen und osterreichischen Variante auf allen sprachlichen Ebenen auf. Z. B. liegt ein Unterschied zwischen der binnendeutschen und osterreichischen Variante im Genus vor: Wahrend im Binnendeutschen Butter ein Femininum ist, benutzt man Butter in osterreichischen phraseologischen Wortverbindungen als Maskulinum - in den Butter gehen. Einen weiteren Unterschied gibt es vor allem in der Valenz der verbalen Phraseologismen. In Osterreich konnen Prapositionen anders verwendet werden als in Deutschland, oder es werden andere Prapositionen an ein Verb oder Substantiv angeschlossen. Beispielsweise wird die Praposition an oft anstatt des binnendeutschen auf verwendet. In dieser Arbeit wurde nur eine sehr begrenzte Menge an Phraseologismen aus den Worterbuchern zusammengestellt. Die Ergebnisse der Analyse sind aus diesem Grund eher tendenzweisend. Es ware interessant, anhand eines Korpus Vernwendungsweisen, Vorkommenshaufigkeiten und Kookkurenzpartner der ostereichischen und der deutschen Varietat zu vergleichen.
