본 논문은 C. P. E. 바흐의 연구에서 심도 있게 다루어지지 않은 그의 푸가를 재평가하는 것에 목적이 있다. 푸가는 대위적인 음악 가운데 짜임새가 가장 정교한 음악으로 흔히 대조적 성격의 즉흥적 프렐류드나 판타지아와 한 쌍으로 이루어져 있기도 하다. C. P. E. 바흐는 여기서 한 걸음 더 나아가 두 악곡을 나란히 배치하는 것이 아니라 이 두 장르를 하나의 음악으로 융합시키고자 하였다. 푸가의 기본 개념과 전형적인 형식적 틀은 느슨하게 유지되고 있는 가운데 주제의 특징과 세부진행에서 그가 즉흥연주기법으로 피력한 바 있는 양식적 특징이 비중 있게 결합 되어있는 것이다. 본고는 C. P. E. 바흐 건반 푸가 전곡(7곡)의 분석을 통해 그가 추구한 즉흥연주기법과의 결합을 고찰한다.

This study has been carried out to investigate Brain in Nei-jing. The results of this study were as follows. 1. Kidney energy becomes the marrow by warm caring function of Meong-mun(命門) and the marrow becomes brain by ascending and gathering between a hole Back-hoi(百會) and a hole pung-ji(風池) 2. Brain is a sea of the marrow that five vital organs are eraporated togather. 3. In Nei-jing(內經), there is a explanation the connectin between brain and mind, thanking by drawing in a concept of head. 4. Brain regulrates physical excercise. 5. There is a direct connection between brain and biosis. 6. Brain achieves function of sense, relating with the five sensory organs. 7. Brain controls a change of emotion. 8. Brain has immunological function.

The 7th national mathematics curriculum lays emphasis on an interrelation of several subjects and a connection between mathematics and real life. In this reason, this study focuses on the enhancement of sound understanding nuclear energy which is one of important factor(concepts or contents) dealt with in the other subjects such as science, environment, social studies, etc.. Recently, even though it is insistent that nuclear energy be so important and request in the future society, there are still strong pro and cons regarding the use of it. In this study, teaching-and-learning materials were developed dealing with using nuclear energy, and consequently they might be used in math class for the purpose of enhancement of mathematical learning ability and of recognition on nuclear energy. In this study, Material 1 included a matter of the necessity for nuclear power plants using the ratio concept, and Material 2 did on a matter of the efficiency of nuclear energy and the unclear of nuclear power plants using ratio-graph, in the elementary and upper school mathematics. Material 3 focused on a matter of the principles of nuclear power plants using the properties of exponential law in high school mathematics. Ultimately, it is hoped in the study that more diverse instructional materials dealing with diverse situations inside and outside mathematics would be developed.

This study is about the analysis on symbolic meaning and kunstwollen of Issey Miyake's art works which is influenced by various external factors such as social and cultural background, nationality and philosophy. Especially, this research focused on 'Pleats Please Issey Miyake' and 'A Piece of Cloth' which are the core of his works. The most important concept of Issey Miyake's works is the relationship of human body and a piece of cloth. Miyake's clothes has provided the time and the space where inspires the vitality into wearer. He accomplishes the most perfect beauty through incomplete beauty of cloth. Miyake wants to express the emotion of the human being through his clothes and tries to make special code between creator, wearer and viewer. Fashion is accomplished in connection with human body, not exists just as 'clothes'. Fashion has valued as an art which expresses the ideology and the sentiment of human being most directly. Issey Miyake who has tried to express human life and emotion has promoted fashion as an important part of art. Miyake is accepting and delivering the history and culture, expressing and communicating empathy, and combining the different fields harmoniously.

In connection with the plan for improving the residential environment gradually by analyzing the present condition of the reconstruction and parcel form of the housing area in a inner area, the main objective of this research is to develop a cooperative urban housing model based on the neighborhood agreement. The parcel form has a structure that is inappropriate for individual reconstruction； thus, the substantial improvement only through the residential environment improvement project has its limitations. As an alternative plan to resolve such limitations, I proposed a system that enables step-by-step reconstruction within the small-scaled blocks through the annexation of the land based on the neighborhood agreement. Nonetheless, I realized that it is difficult to apply such reconstruction system to individual housing. Therefore, I presented a design concept on the cooperative urban housing project as a residential form for the reconstruction inside blocks. A model plan vouches for its effectiveness. To apply substantially the cooperative urban housing plan based on the neighborhood agreement, we need to supplement the sectional plan system.

Avionic databuses fulfill a critical function in the connection and communication of aircraft components and functions such as flight-control, navigation, and monitoring. Ethernet-based avionic databuses have become the mainstream for large aircraft owning to their advantages of full-duplex communication with high bandwidth, low latency, low packet-loss, and low cost. As a new generation aviation network communication standard, avionics full-duplex switched ethernet (AFDX) adopted concepts from the telecom standard, asynchronous transfer mode (ATM). In this technology, the switches are the key devices influencing the overall performance. This paper reviews the avionic databus with emphasis on the switch architecture classifications. Based on a comparison, analysis, and discussion of the different switch architectures, we propose a new avionic switch design based on a time-division switch fabric for high flexibility and scalability. This also merges the design concept of space-partition switch fabric to achieve reliability and predictability. The new switch architecture, called space partitioned shared memory switch (SPSMS), isolates the memory space for each output port. This can reduce the competition for resources and avoid conflicts, decrease the packet forwarding latency through the switch, and reduce the packet loss rate. A simulation of the architecture with optimized network engineering tools (OPNET) confirms the efficiency and significant performance improvement over a classic shared memory switch, in terms of overall packet latency, queuing delay, and queue size.

Steel angles are widely used in roof trusses as web and chord members and in lattice towers. Very often angle members are connected eccentrically. As a result, not only an angle member is under an axial force, but it is also subject to a pair of end eccentric moments. Moreover, the connection at each end provides some fixity so neither pinned nor the fixed end represents the reality. Many national design codes allow for the effects due to eccentricities by modifying the slenderness ratio and reducing the compressive strength of the member. However, in practice, it is difficult to determine accurately the effective length. The concept behind this method is inconsistent with strength design of members of other cross-sectional types such as I or box sections of which the buckling strength is controlled by the Perry constant or the initial imperfection parameters. This paper proposes a method for design of angle frames and trusses by the second-order analysis. The equivalent initial imperfection-to-length ratios for equal and unequal angles to compensate the negligence of initial curvatures, load eccentricities and residual stresses are determined in this paper. From the obtained results, the values of imperfection-to-length ratios are suggested for design and analysis of angle steel trusses allowing for member buckling strength based on the Perry-Robertson formula.
