오늘날 국제경제체제에서 가장 중요한 역할을 하고 있는 화학공업의 원자재의 수요를 앞으로 어떻게 공급할 것인가 하는 문제를 계획하자면 업계는 물론 학계와 정부의 공동협력이 필요하다. 화학공업이 필요로 하는 원료의 앞날은 기술과 경제적인 관점에서만 볼 것이 아니라 정부와 사회적인 이해관계가 좌우한다. 세계 화공업계의 「거인」인 미 듀뽕사의 샤피로회장은 78년 캐나다 토론토에서 열린 세계유기원료회의에서 유기화학원료의 앞날을 이런 측면에서 다음과 같인 전망하였다. <현원복역:본지 편집위원>

영국 제도에는 동굴이 꽤 많지만 지평이 낮고 평탄하기 때문에 세계적인 규모에 달하는 것은 없다. 북서 요크샤의 잉글보르ㆍ마람 지방에는 영국 제일의 멋진 동굴이 발달하고 있다. 가장 유명한 것은 게핑ㆍ길 동굴로, 잉글보르 구릉의 동쪽 사면에 입구가 있다. 거대한 수직굴로, 휄백강이 이곳에서 지하로 스며들어 가며 곧장 폭포가 되어 110m를 흘러 떨어져 높이 35m, 폭 35m, 길이 150m의 거대한 홀의 천정에 연결된다. 이것이 영국 제일의 멋진 동굴로 발달하고 있다. 물은 동굴 마루의 자갈, 모래나 암괴의 틈으로 흘러들어가 없어진다.(중략)

This study aims at investigating Geisha costume hidden in the history until now and how the fashion of Geisha style is expressed in accordance with character through the movie 'Memoirs of a Geisha'. Major contents of the text consist of studies including the historical background and characteristics of Geisha costume in Chapter 2, the Japanese style expressed in the movie through the analysis of the work in Chapter 3, The movie brought in an opportunity to spread the mysterious culture and art of Japan to the world, making Japanese style an important interest in the world of fashion as well. In a way to study this, the investigation was carried out through literature data, DVD and newspaper of , fashion magazine, articles from the Internet, ete. The Geisha trend has made the hot blast blown harder in such ways to affect not only fashion but also cosmetics, electronic appliance, interior, etc. In S/S 2006, it was not limited to the Japanese style but diffused to the Orientalism in China, India, Korea, etc. It can be said that this study has its significance to be a starting point in investigating the special characters of Japanese Geisha costume hidden up to now. In the studies following in the future, the formative beauty demonstrated per Japanese designer needs to be more studied. Furthermore, it seems noteworthy to analyze and compare Chosun Dynasty's Kisaeng with Japanese Geisha.

Spatial web objects refer to web documents that contain geographic information. Recently, services that create spatial web objects have increased greatly because of the advancements in devices such as smartphones. For services such as Twitter or Facebook, simple texts posted by users is stored along with information about the post's location. To search for such spatial web objects, a method that uses spatial information and text information simultaneously is required. Conventional spatial web object search methods mostly use R-tree and inverted file methods. However, these methods have a disadvantage of requiring a large volume of space when building indices. Furthermore, such methods are efficient for searching with many keywords but are inefficient for searching with a few keywords.. In this paper, we propose a spatial web object search method that uses a quad-tree and a patricia-trie. We show that the proposed technique is more effective than existing ones in searching with a small number of keywords. Furthermore, we show through an experiment that the space required by the proposed technique is much smaller than that required by existing ones.

Many studies are currently in progress concerning about recycling due to the environmental problems and the drain of the resources. Nowaday, the problems on wastes are increasing thus studies on the construction waste are necessary which is the greater part of domestic wastes. And much more studies on the waste concrete which takes a large part of construction wastes are in progress but the studies on how to handle the waste concrete economically are unsatisfactory. This study suggests the analyzation of the economical way of handling the waste concrete by processes depending on the cost which needed in the each process, and can be the fundamental data of the future construction waste recycling system.

In this paper, the power factor correction circuit using a parallel drive method is proposed so that the high power inverter air-conditioner with 3[hp] compressor motor may obtain the cost down and the improved performance. The adequate design porcedures are presented to reduce the material costs by eliminating the power factor imprving LC filter and derating output capacitor and inverter switches. Using the determined components. the proto-type circuit with 6[kW] power consumption is built and tested to verify the operation of the proposed circuit.

본 논문에서 필자는 수학에 대한 구조주의적 해석들은 수학의 객관성을 설명하는 문제인 비공허성의 문제를 해결하지 못하고 있음을 보이고자 한다. 제거적 구조주의가 비공허성의 문제를 해결하지 못한다는 것은 대부분의 수학철학자들 사이에서 공유되는 견해이며, ante rem 구조주의는, 케래넨의 논증을 수정한 필자의 강한 논증에 의하면, 수학적 대상들에 대한 적절한 동일성 설명을 결코 제공할 수 없기 때문에, 결국 비공허성의 문제를 해결하지 못한다. 또한, 양상 구조주의자인 헬만의 경우에는, 비공허성의 문제에 대한 양상 구조주의적 해결을 가능케 해주는 주장(산수와 관련하는 경우, "${\omega}$-순서열 체계가 논리적으로 가능하다")에 이르는 그의 증명이, 필자의 판단에 따르면, 논점 선취의 오류를 저지르고 있다.

Dynamic analysis of a three-axle heavy truck is carried out with rigid body model and flexible body model. To see the effects of chassis flexibility, the chassis is modeled as flexible body. The mass matrix, stiffness matrix, and vibration normal modes of the chassis are obtained by a finite element analysis program, and four vibration normal modes are used in the flexible body model. The vehicle model consisting of a frame, a cab, suspensions, an engine, a deck, a seat, and tires, has total 77 degrees of freedom. The result shows that the peaked acceleration in the flexible model is lower than that of the rigid body model.

The morphology of fungal growth, which is an important variable for separability and rheological property of fermented medium, was quantified with fractal geometry Fractal dimensions were determined for submerged growth of two industrially important fungi, Aspergillus niger and Aspergillus oruzae. The tendency of pellet formation was related to the fractal dimension of fungi.
