This study is about the polyphony music proportion which appears today in the Architecture space. In the field of interior architecture, there have been many tries of applying characteristics of music, such as abstraction and nature of time for users of space to have new experience. It has been possible because architecture and music have similarities in many ways. Regarding using proportional characteristic in architecture and music, the both fields are enormously related in some ways. The purpose of this study is explaining of possibility of architectural expression in music and suggesting a way of analysing architectural design based on musical elements emphasizing proportional characteristic. Therefore, it is going to analyse Counterpoint of Bach, which is well expressed in music and compare it with proportional characteristic of space through this study.

In this paper, we suggest a virtual machining system that can simulate cutting forces of ball end milling at the stage of part design. Cutting forces, here, are estimated from the machanistic model that uses the concept of specific cutting farce coefficient. To this end, we need undeformed chip thickness which is used for calculating chip load. It is derived from the Z-map data of a CAD model. That is, chip load is the height difference between the cutting tool and the workpiece at an arbitrary position. The tool contact point is referred from the cutter location data. On the other hand, the workpiece height is acquired from the Z-map model of a CAD data. From the experimental verification, we can simulate machining process effectively to the slot and the side cutting of ball end mill.

Head of Panax ginseng indicates its growth number of years and it has been widely used for supplying energy to weak person. However, the underlying mechanisms are not sufficiently reported. Thus, we inclined to study head of Panax ginseng in rheumatoid arthritis and inflammation. Rheumatoid arthritis (RA), an organ-specific inflammatory disease of human, is characterized by a chronic and destructive inflammatory reaction and possibly autoimmune in etiology. It is occurred when the synobial membranes of joints and many other tissues of the body is attacked which induces significant health problem in terms of numbers of sufferers (U.S. incidence 23.7/100,000), and the synobial inflammatory is dominated by activated macrophage.

There is an agreement that sociocultural forces affect on the types of arts. There have been a little attempts to draw analogy between architecture and music. There are many objective and subjective factors for this to be true. If, however, the two arts are out of much the same social conditions, they show a degree of conformity in design and general organization. Our study shows the interrelationship between the Residential Space and structure of music. In order to clarify the interrelationship between architecture and music, the study examines ten Residential Spaces suggested by Yi-Jinkyung. The Residential Spaces are analyzed by using theory of Space Syntax. The structure of music is analyzed by tonality, counterpoint and harmony. The comparison between the Residential Spaces and music follows : From Renaissance to the 19th century, they have the same tendency to 1) openness & closure to the outer space and 2) the netting diagram in the inner space & Counterpoint 3) the tree diagram in the space & Harmony

본 연구에서는 개발도상국 해외투자 입지 결정요인을 실증 분석하였다. 분석의 결과 입지요인인 피투자국 시장규모, 경제 발전 정도, 경제성장율, 인적자본의 질, 경제의 개방도, 현지시장 매력요인의 대위변수인 현재 외국인 투자 유치액등은 해외투자 유치에 정의 영향을 미치는 요인으로 나타났다. 수정된 중력 모형에서 중 요변수인 피투자국의 모든 투자국들로 부터의 상대적인 시장가중치를 감안한 원격성은 낮을수록 해외투자 유치가 활발한 것으로 나타나고 있어 거래비용이나 현지시장 친숙도가 중요한 해외투자 고려 요인임을 알 수 있었다.

In this paper, we propose a fast implementation of Bilateral filter for tone mapping algorithm. Bilateral filter is able to preserve detail while at the same time prevent halo-ing artifacts because of improper scale selection by ensuring image smoothed that not only depend on pixel closeness, but also similarity. We accelerate Bilateral filter by using a piecewise linear approximation and recursive Gaussian filter as its domain filter. Recursive Gaussian filter is scale independent filter that combines low cost 1D filter which makes this filter much faster than conventional convolution filter and filtering in frequency domain. The experiment results show that proposed method is simpler and faster than previous method without mortgaging the quality.

신경망이론은 분산기억성질과 병렬국소처리를 수행하는 뇌의 활동을 이론화한 수학모형이다. 이러한 신경망이론의 장점은 분류문제, 대규모로 결합된 최적화문제, 비선형 사상문제 등에서 잘 나타나므로, 이 점을 이용하여 복잡한 강우의 예측을 시도하였다. 신경망이론을 적용하기 위해서 연속적인 값으로 표시되는 입력자료와 출력자료를 학습한 후 강우예측을 시행할 수 있는 다층신경망 모형을 구성하였다. 신경망이론에 의한 강우예측은 서울지역과 소양강유역의 1 시간 대위 강우자료에 적용하였다. 그 결과는 대체로 만족할 만하였다. 따라서 신경망이론은 양질의 자료가 충분히 확보될 경우복잡한 강우현상을 잘 예측할 것으로 기대된다.

The different core-modified porphyrins 21-thia-23-carba-12-aza-5,10-dimesityl-15,20-diphenylporphyrin (6), and their N(12)-methyl derivatives (8) were synthesized by acid-catalyzed [3+1] condensation of the corresponding 16-thia-5,10-dimesityltripyrromethanes and 2,4-bis[(α-hydroxy-α-phenyl)methyl]pyrrole. Spectroscopic evidence indicates the existence of two different tautomeric forms at room temperature in porphyrin (6). A third form of tautomer was observed when the temperature was lowered to 223 K. The most stable tautomer is one in which the nitrogenic proton resides outside the core of the macrocycle. The ratio of the three different tautomers (outer N-H/ two inner N-H, i.e. 6/12/13) was 1/l/0.5 in the case of (6) while the ratio of 1/l/0.3 was observed in the case of (10). In the case of 21-oxa-23-carba-12-aza-5,10,15,20-tetraphenylporphyrin (7), the only stable tautomeric form observed by 1H NMR was the one that nitrogenic proton resides inside the core on
