According to the Flow Theory, when the perceived level of Challenges of player and his skill are high, he is able to experience the flow state. What does the skill mean in the Flow Theory? This study suggests that the self-efficacy of the actor should be concerned to understand the perceived level of actor's skill in relation to the level of Challenges and his personal characteristics. This study hypothesizes the equity-distribution of extrinsic reward and the positive reputation influence the player's self-efficacy, and his self-efficacy affect the flow experience. This hypothesis is confirmed by the structure equation model test. This result can serve to understand skill related on the flow theory, and what factors players to get flow experience are given by.

In this paper, we propose a direction of teaching method for future generations. In order to suggest such the direction, teaching and learning materials that integrate coding activities and mathematical modeling were developed through top-down and bottom-up processes. Coding and engineering experts and mathematics education experts developed teaching and learning materials through councils (top-down courses) and applied them to 24 high school first graders based on student responses (bottom-up courses). Additionally, the developed curriculum helped students increase interest and motivation and realize conceptual understanding, problem posing, and problem solving in mathematics. On the basis of these results, it provided an idea about how to develop curriculum combining mathematical modeling with coding activities, needed for the fourth industrial revolution.

There are some advantages of developing applications based on the object oriented concepts. One os them is that it is possible to reuse the existing designs and products. This paper provides a formal method for the reorganization of class hierarchies for the object extension in the object oriented design phase. In this paper, we introduce classes, and edges to represent the inheritance and aggregation relationship between classes. Based on the graph, we define an order relation(called the object extension) between class hierarchy graphs. And also we present a set of five basic transformations preserving the object extension relation. The set is proven to be correct and complete. The results of this paper help form a theoretical basis for the extension and reorganization object-oriented application systems.

최근 국내외에서 기상이변에 따른 물 부족에 대응하고 먹는 물의 생산과 공급 효율성 향상을 위하여 스마트워터그리드에 대한 연구가 활발히 진행되고 있는 경향으로 이는 상수도 인프라시설의 운영오류, 자연재해, 사이버를 통한 의도적 공격 등에 대해 안전하고 신뢰성이 높은 시스템을 구축하기 위한 것이다. 또한 상수도 분야에서는 스마트 미터링 개념을 도입하여 상수관망에서 발생되는 각종 사고나 물 손실을 저감하기 위한 노력이 시도되고 있는 실정이다. 일반적으로 누수량이 많을 경우에는 누수의 징후가 지표면에서 확인이 가능하나 미세한 경우 탐사장비의 운영이나 인력의 투입을 통해 가능하다. 물 공급계통인 상수관망에서 물 손실을 저감시키기 위한 방법중 하나로서 수도미터로부터 기록되는 물 사용량 데이터를 이용하여 누수패턴을 추출함으로써 누수감시가 가능하도록 하는 모형을 개발하고자 하였다. 이는 탐사장비에 의한 누수감지와 상호 보완적을 활용할 수 있는 것으로서 사용량 자료를 분석하여 사전에 처리된 자료의 노이즈와 결함 있는 계측값을 필터링시키는 기법이 도입된 것이며 신속한 감지를 통해 누수 지속시간을 감소시킴으로서 누수량의 저감을 목표로 한다. 물 공급 네트워크를 보다 더 효율적 만들 수 있는 누수 감시모형은 상수관망의 운영에 필요한 정보를 도출하기 위하여 보다 정확하고 다양한 수학적 및 통계적 분석을 기반으로 구성되어 누수 외에도 각종 결함을 찾아내는 역할을 수행할 수 있다. 향후 다양한 지역을 이러한 수용가의 물 사용량 미터링 결과를 토대로 실제 사용량과 누수량을 분리하여 분석함으로써 국내 실정에 적합한 누수감시 기술배발 토대를 마련할 수 있을 것으로 판단되며, 누수저감을 위한 실질적인 상수관망의 운영관리 효율향상의 정보로서 활용이 가능할 것으로 판단된다.

Die vorliegende Untersuchung zielt darauf ab, erstens die Entstehung der $Fr{\ddot{u}}hromantik$ in Bezug auf damalige Kantkritik zu betrachten, zweites Jacobis Gedanke, der die Bewegung der $Fr{\ddot{u}}hromantik$ $ansto{\ss}t$, mittels seines Zentralbegriffs "Unbedingtes" und "$Gef{\ddot{u}}hls$" zu rekonstruieren und drittens den Kerngedanke der $Fr{\ddot{u}}hromantik$, der die unendliche $Ann{\ddot{a}}herung$ betont, durch Novalis zu $erl{\ddot{a}}utern$. $F{\ddot{u}}r$ Jacobi wird das Unbedingte als "Glaube" angesehen, weil es nicht nur der $M{\ddot{o}}glichkeitsgrund$ des Wissens ist, sondern die Vermittlung des Wissens ${\ddot{u}}berschreitet$. $W{\ddot{a}}hrend$ es die Bedingung des Wissens ist, ist es das "Sein", das den Bereich des $Bewu{\ss}tseins$ transzendiert. Somit Jacobis "Unbedingte" bzw. "Ur-Sein" ist nicht nur die Grundlage des metaphysischen Monismus, sondern die realistische Substrat, die auf den Bereich des Wissens nie reduziert wird. $F{\ddot{u}}r$ Novalis wird das Unbeclingte dem $Bewu{\ss}tsein$ nicht gegeben, vielmehr ist es der Gegenstand der Sehnsucht und des Strebens. Hier wird die Philosophie als unendliche $Ann{\ddot{a}}herung$ zum Unbedingten bestimmt. Philosophie ist sowohl die $urspr{\ddot{u}}ngliche$ $T{\ddot{a}}tigkeit$ des mit dem Transzendeten $ber{\ddot{u}}hrenden$ $Gef{\ddot{u}}hls$ als der unendliche Trieb, der den Grund zu erkennen versucht.

The purpose of this study is to develop an evaluation model to measure the core competences of actual play workers by exploring what competences are necessary for them to provide quality play. Based on literature review, we selected five core competences : knowledge of play, program development, understanding play culture, creativity, and information sharing & applying. In order to achieve the research purpose end, a two-round Delphi survey was conducted on 10 play and education experts. The findings drew scholarly consensus on the competences of play workers to have and proposed basic data by developing competences evaluation model to measure them. Each of the key competences has three sub-conpetences, each of which included two behavior elements. Furthermore, this study presented future research directions so that play can be voluntarily planned and supported in a social and cultural context.

'Divisor and multiple' is the topic included both in the elementary and in the secondary mathematics curriculum, but there has been lack of research on it. It has been reported that students have a difficulty in understanding the meaning of the greatest common divisor (GCD) and the least common multiple (LCM), while they can find out GCD and LCM. Against the lack of research on how to overcome this difficulty, this study designed teaching methods with a model for visualization to emphasize the meanings of divisor and multiple in finding out GCD and LCM, and implemented the methods in one fourth grade classroom. A questionnaire was developed to explore students' solution methods and interviews with focused students were implemented. In addition, fourth-grade students' thinking was compared and contrasted with fifth-grade students who studied divisor and multiple with the current textbook. The results of this study showed that the teaching methods with a specific model for visualization had a positive impact on students' conceptual understanding of the process to find out GCD and LCM. As such, this study provides instructional implications on how to foster the meanings of finding out GCD and LCM at the elementary school.

With the development of cultural industries and technology, digital video marketing has grown immensely and 'Book Trailer' are now one of the main methods of promoting a title in publishing industry. The demands are growing, but the development lacks basic theoretical foundation and systematic structure. At this crucial moment, basic theoretical research on Book Trailer is necessary to establish a solid foundation for the medium to expand. In this study, I have focused on defining the basic concepts of Book Trailers and analyzing the classification of Book Trailers. In sorting the type of Book Trailers, content and formal appearance were used as standards. As a result, I was able to classify the content genre into message type, conflict type, character type using the elements of story. The formal appearance genre was classified into still photography type, motion typography type, interview type, story movie type and animation type.

Israel craves peace and freedom. Israel has won many wars and conflicts militarily. They have developed strategic thinking based on the data, unique culture, and peacetime preparation system accumulated so far, and the strategic culture based on it contributes to fostering elite strong forces by presenting directions to security strategies.The strategic culture formed by Israeli beliefs, behavioral patterns, and identity influenced strategic thinking and the usefulness of security strategies. The purpose of this study is to redefine the concept of strategic culture by referring to the methodological discussion of strategic culture theory and to examine how useful strategic culture has provided strategic thinking and security strategies. In addition, based on the impact of Israel's strategic culture on security strategy, I would like to present implications for Korea's security strategy.
