It is the purpose of this study to help computational estimation study to settle down in effective teaching method through analysis how students are understanding computational estimation and what occurs using computational estimation in actual life problem situations. I set 3 cases to accomplish these purposes. (1) How students are understanding computational estimation? (2) How students' computational estimation ability is in applying actual life problem situation? (3) What is students' different attitudes in an actual life problem situation before studying computational estimation and after? To accomplish the purpose, I chose 6 third grade students and taught "Computational estimation using actual life problem situation" and analyzed students' computational estimation processing. Then I arranged the computational estimation processing in an actual life problem situation and differences between the before and the after. As a result, I obtained the followings. (1) Need of estimation: Every students could recognize the need of estimation with experiencing an actual life problem situation. (2) Choosing the order of decimals: Students could choose appropriate order of decimals according to an actual life problem situations. (3) Using strategy: They usually use rounding strategy and quite often use special number and compatible number strategy. 본 연구는 수학학습 능력이 서로 다른 3학년 6명의 학생을 대상으로 총 6회의 실생활 문제 상황을 활용한 어림수업을 실시하여 어림에 어떤 변화가 보이는지 분석하고 어림학습 전과 후에 실생활 문제 상황 학습지를 투입하여 그에 대한 변화를 비교해 보았다. 실생활 문제 상황을 활용하여 역할극으로 진행된 어림수업에서 학생들은 자신의 생활과 친숙한 문제 상황 속에서 어림을 사용하였으며, 문제 상황에 따라 적절한 자리 수를 결정할 수 있음을 확인하였다.

In liquid crystal display device, the alignment of the liquid crystal molecules plays the important role to characterize the image quality of LCD. The rubbing process of conventional technique has many problems for LCD such as generation of electrostatic charge and light leakage. On the other hand, the chemical method, photoalignment process, is a non-contact method that not only solves the problem of rubbing process, but also can has the effect of increasing yield and contrast ratio. Therefore, many kind of research have been conducted on photoalignment process. In this study, we have synthesized the photopolymer based on chalcone moiety-containing side chain in the backbone of polymaleimide. Originally, Toluene and Methyl Ethyl Ketone (MEK) were used for film casting solution. However, Tri-Acetyl Cellulose (TAC) film is damaged by MEK solution. Therefore, we replaced the solvents MEK of film casting solution with PGMEA and observed the photoalignment properties on TAC film.

Wolfgang Amadeus Mozart lived a short life of 35 years at the end of the 18th century in classicism, but his music has been played most frequently and his life and work of art have been studied by numerous scholars for the past two hundred years. Mozart left over six hundred works including operas, symphonies, concertos, chamber musics, sonatas, and masses, and his genius shines through his piano music. He composed about eighteen piano sonatas. KV.333 was composed during or immediately after his stay in Paris, and together with five other sonatas composed in the same period. It is recognized for its outstanding artistic value. The present paper deals with Mozart's composition techniques, characteristics of his sonatas, and their performance alternatives with a focus on KV.333, a typical Mozart sonata. In accordance with the model of classicist sonatas, KV. 333 is composed of three movements : fast-slow-fast. The first movement in sonata Allegro form features a contrast between the lyrical first theme and the intensive second theme. Generally second movements of Mozart is very excellent. This second movement is also outstanding, and is characterized by the theme and its ornamental variation. The last movement of this sonata is a flowery rondo with cadenza and is marked by its concerto characteristics. It is interesting to study the entire process in which a piece of music is created and written by a composer, and is performed by a musician. This paper attempts at a unified treatment of theory and practice by analyzing a piece of music from a theoretic and an aesthetic perspective by examining problems faced in actual practice, and by suggesting some performace alternatives.

The purpose of this study is to identify the conflict between residents and governments in partnership arising from the designation of National Important Agricultural Heritage for Damyang Samdari village and to suggest directions for improvement. To this end, residents of Samdari Village in Damyang, designated as an important national agricultural heritage, were interviewed. Interviews were analyzed through grounded theory, categorized into open coding, axial coding, and selective coding, and a paradigm model was constructed. Through this, the central phenomena of resident participation patterns currently appearing in the village were identified, and causal, contextual, and intervening conditions were analyzed. Causal conditions were analyzed as one-sided administrative treatment, assortment matching project, one-time plan, excessive dependence of residents and economic damages of residents at the beginning of the designation of national important agricultural heritage. As a result, conflict between residents and local governments occurred as a central phenomenon, and contextual conditions such as decline in the competitive of bamboo resources and frequent change in managers were also affecting the central phenomenon. As intervening conditions to alleviate the central phenomenon, there are local government’s purchase of bamboo fields and fragmentary business effects. The action taken by the residents and officials in response to a fixed conflict is called an action-interaction strategy. Residents refused to change and settled in reality, and local governments avoided conflict. From the beginning of the designation to the present, the villagers gradually lost interest in the National Important Agricultural Heritage due to problems and conflicts that occurred in the process of forming a partnership in the National Important Agricultural Heritage project. Based on the analyzed model, a plan to build the partnership standards on Damyang bamboo field to secure the sustainability of the field and increase the practicality of resident participation, that is partnership, was suggested.
