이제 GIS 표준은 국제적으로 공인된 과정을 거쳐 제정되고 있다. 이러한 과정과 표준자체의 중요성은 물론이며 표준 개발을 의한 GIS 표준 하부구조 즉 범 세계적 공간 정보 하부 구조 (the Global Spatial Data Infrastructure: GSDI) 의 개발도 아주 중요한 것이다. 기술이란 항상 변하고 있는 것이기에 GSDI등 표준 하부구조가 구축되면 새로운 GIS 표준은 이러한 하부 구조에 의해 쉽게 개발 되게 된다. 본 논문에서는 지금까지 구축된 공간 정보 표준 하부 구조는 어떠한 것이 있고 또 앞으로의 GIS 표준 개발 방향은 어떻게 나아가야 할 것인지 살피고자 한다.

Authors have developed the method of selecting the efficient variant of designing a systems or products from a some number of competition variants in the conditions of vagueness of the initial information. Registration of information vagueness degree concerning the quantity index values is carried out of the expense of giving to the expert the possibility of using different methods of index evaluation numerical evaluations with physical scale; phrases of limited language; and points evaluation. Using of this method and software is important for marketing research, for systems of quality control of products.

Fishman et al.(1987)의 연구를 시작으로 인공위성 자료를 이용하여 적도지역의 대류권 오존에 대한 연구가 활발해졌다. 적도지역의 대류권 오존의 분포는 Atlantic Ocean에서 최대값을 가지며 Pacific Ocean에서 최소값을 가지는 wave pattern을 보인다. S. America와 S. Africa에서 연중 dry season(6-9월)에 biomass burning로 인해 대류권 오존의 최대값이 나타난다. 인공위성 자료를 이용한 대류권 오존을 구하는 방법은 다음과 같다. (중략)

Tetralogy of Fallot (TOF) is an index lesion for all paediatric and congenital heart surgeons. In designing an appropriate operation for children with TOF, the predicted postoperative physiology must be taken into account, both for the short and long term. A favourable balance between pulmonary stenosis (PS) and pulmonary insufficiency (PI) may be critical for preservation of biventricular function. A unified repair strategy to limit both residual PS and PI is presented, along with supportive experimental evidence. A strategy for dealing with coronary anomalies and some comments regarding best timing of operation are also included.

본 실험에서는 수술적 방법을 이용하여 난관 절제술을 실시한 성숙 난자의 회수율과 카데터를 이용한 난자 회수율 그리고 새롭게 고안된 개 난자 회수용 니들을 이용한 회수율을 비교하였으며, 각각의 회수 방법이 성숙난자의 외형에 미치는 영향을 조사한 결과는 12두에서 난관절제술로 채취한 성숙난자의 회수율은 89.7% 이었다. 수술적 회수방법에서는 본 연구실에서 개발한 난자 회수용 니들을 난관내에 삽입-결찰한 후 난관-자궁 접합부에서 난자 회수용 배지를 관류하는 방법으로 평균 83.0%의 회수율을 얻었다. 이 같은 결과는 TomCat 카테터를 이용한 회수율 (68.9%)과 난자 회수용 니들을 결찰하지 않고 관류한 방법 (73.5%) 보다 유의적으로 높은 회수율을 나타내었다 (p<0.05). 또한 난관 절제술과 각각의 수술적 방법으로 회수한 난자의 형태학적 차이는 관찰할 수 없었으나 난관 절제술과 난자회수용 니들을 결찰하여 회수한 난자의 형태와 난질이 Tom Cat 카테터나 결찰하지 않은 니들을 이용하였을 때보다 영향을 덜 받는 경향을 나타내었다 (각각 72.0%, 73.8%와 62.8%, 69.6%).

Miscibility of poly(4-vinylpyridine) (P4VP) blends with poly(vinyl acetate-co-vinyl alcohol) (VAc-VAL copolymers) was investigated as a function of comonomer composition of VAc-VAL copolymers. Differential scanning calorimetry (DSC) and thermo-optical microscopic (TOM) analysis confirmed that P4VP is miscible with VAc-VAL copolymers containing more than 30 mole% VAL. Fourier transform inflated (FT-IR) spectroscopic analysis revealed that the strong intermolecular hydrongen bonding interaction between the vinylpyridine and VAL hydroxyl group was formed. Theoretical phase diagram was constructed by the calculation using the Association model, a thermodynamic model for hydrogen-bonded polymer blend systems developed by Coleman et al. The calculated theoretical binodal phase diagrams were in good agreement with the experimentally determined cloud point curves.

The movement of characters in ceil animation is the art that gives the feeling of movement. The movement expressed naturally and well done makes the scene more dramatic and interesting. The history of 3D animation is not fully riped yet but it has shown powerful impact. The genre of 3D has come closer to us, yet it has given freshness and problems at the same time. One of the problems is the awkwardness of movement. Overplaying, stretching and squashing of character, was extremely difficult to accomplish using the prior technique of 3D so! ftware. It was not very effective so animators have avoided doing it. However, advanced technique of 3D software, so to speak, ‘stretch and squash’, overcomes the limitation of movement. The new form of character animation can be accomplished. The theme of this paper is about the analysis and comparison of ‘stretch and squash’ in cell and 3D animation.

A GNSS/INS integration system can not provide navigation solutions if there are no available satellites. To overcome this problem, a vision sensor is integrated with this system. Since generally a vision aided integration system uses only feature point to compute navigation solutions, it has a problem in observability. In this case, additional landmarks, which is priory known points, can improve the observability. In this paper, the observability is evaluated using TOM/SOM matrix and Eigenvalues. There are always the observability problems in the feature-point-only case, but the landmark-use case is fully observable after the $2^{nd}$ update time. Consequently the landmarks ensure full observability, so the system performance can be improved.
