Abstract:
The present invention relates to a cooperative design information management system and method. The system comprises: a main server which registers standard design information relating to product development and to products, generates initial cooperative company design information, and registers the initial cooperative design information to a management server; a cooperative server which downloads the initial design information from the management server, conducts detailed design work on products on the basis of the initial cooperative design information, and generates design information containing drawings and technical documents; and said management server which receives the initial cooperative design information and the generated cooperative design information, further generates final design information in which the drawings and technical documents of the products are interconnected on the basis of the received information. The main server receives the final design information from the management server, and updates the standard design information with the final design information. The thus-configured system of the present invention provides various items of design information such as drawings and technical documents based on information on parts and also provides a cooperative environment for one main company and a plurality of cooperative companies. Further, the system of the present invention strengthens security functions for the cooperative design information for each cooperative server of the plurality of cooperative companies.
Abstract:
The present invention relates to a biodegradable multi-filament false-twisted yarn having a bulky structure, a production method for the same, and an application for a culture material using the same. The biodegradable multi-filament false-twisted yarn according to the present invention is obtained by the false twisting multiple filaments made from a biodegradable polymer material. By giving the multi-filament false-twisted yarn made from a biodegradable polymer material additional bulkiness of from 150 to 1,000 parts % in addition to the inherent bulkiness and outstanding feeling of softness of false-twisted yarns, the false-twisted yarn of the present invention allows cell culturing in the bulky structure and can suitably be used in cell delivery or drug delivery.
Abstract:
The present invention relates to a lyotropic chromonic liquid crystal composition, a method for the manufacture of a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention contains a chromonic liquid crystal compound and a monomer having mutually opposing acid/base characteristics.

Abstract:
An embodiment of the present invention may provide a load-distributing harness comprising: a self-inflatable shocking-absorbing structure unit including an outer cover member having a receiving space formed therein, a cushioning pad disposed in the receiving space and exerting elastic force against an external stimulus, and an air injection layer which comes in contact with the cushioning pad and includes an air-absorbing member forming a closed space within the outer cover member, wherein air is automatically filled in the closed space through an air injection hole due to a pressure difference between the air injection layer and the outside of the outer cover member.
Abstract:
The present invention relates to a novel epoxy compound having a spacer between a core and an alkoxysilyl group, a method for preparing the same, a composition comprising the same, a cured product, and a use thereof. The epoxy compound exhibits excellent heat-resistant characteristics, particularly a low coefficient of thermal expansion and a high glass transition temperature (which includes Tg-less which does not exhibit glass transition temperature), and an improved brittleness in a composite and/or excellent flame retardant characteristics in a cured product. The present invention provides: an epoxy compound having an alkoxysilyl group which has passed through a spacer group which has at least two epoxy groups, at least one alkoxysilyl group, and a predetermined number of hydrogen, hydroxy groups and/or alkenyl groups; a method for preparing the epoxy compound by means of a step of introducing a spacer group and an epoxy group and an alkoxysilylation step; a method for preparing the epoxy compound by means of a step of introducing a spacer group and an epoxy group, an alkenylation step and an alkoxysilylation step; a composition comprising the epoxy compound; and a cured product and a use thereof. The epoxy composition comprising an epoxy compound having an alkoxysilyl group which has passed through a spacer group according to the present invention exhibits enhanced heat-resistant characteristics, i.e. effects of reducing CTE, increasing glass transition temperature or exhibiting no glass transition temperature (hereinafter referred to as 'Tg less') in a composite. Furthermore, the epoxy composition exhibits improved brittleness. In addition, the cured product of the epoxy composition comprising the epoxy compound having an alkoxysilyl group which has passed through a spacer group according to the present invention exhibits excellent flame retardant characteristics due to introduction of the alkoxysilyl group.
Abstract:
A method for producing a gas hydrate by reacting a plurality of guest gases and water, according to the present invention, is characterized by the solubility of a first guest gas in water which is higher than the solubility of a second guest gas in water, and the pressure for producing a gas hydrate of the second gas is lower than the pressure for producing a gas hydrate of the first gas. Existing methods for producing gas hydrates lowered economic feasibility and productivity by reacting a single guest gas with water, but the present invention overcomes these problems thereby improving hydrate production efficiency while facilitating gas hydrate production at a lower pressure.
