Through the surge of intelligence-based technology, in which information and communication are the main production means, and the ground-breaking innovation of technology, computing, communication, broadcasting have integrated. And this have led to automated, information-based and communication networked society, and the information age. To cope with this movement toward information-based society, offices of interior design are increasingly taking advantage of the Internet and searching for e-commerce business. Many interior design onces have opened up homepages and interior design-related companies are currently in preparation for new advertisement and marketing through the Internet. The purpose of this study is to examine the level of Internet usage by interior design-related websites and information for maintenance of such websites. This study analyzes these websites by their contents and solutions.

This paper proposes a form-based distributed database design methodology ($FD^3$). The methodology consists of five design phases such as (i) form requirement analysis (ii) schema integration (iii) distribution analysis (iv) distribution design, and (v) local logical/physical design. In the $FD^3$, all the important design information for each phase is obtained by using an organizations forms, Users requirements are analyzed by using forms that contain logical and quantitative information for distribution design. $FD^3$ resolves naming conflicts by employing SQLs based on the form field data in the schema integration phase. Furthermore, $FD^3$ enhances the quality of distributed database design by incorporating communication costs into the design model. A real-life case is illustrated to demonstrate the usefulness of the $FD^3$.

In the initial step of BIM based architectural design process, workloads are increased and the decision making process becomes more complex than those of the conventional design process. Technologies regarding distribution, exchange, classification, verification of BIM data are fundamental elements of construct environment for information sharing based on BIM. Interoperability of BIM model data is another issue to integrate BIM model. To improve interoperability in BIM-based collaboration, a model for utilizing formal&unformal design informations is suggested. Futhermore, Prototyping the model and practical test is conducted for advancement of data exchange making design data richen.

The development of computer integrated systems for structural design requires models to describe and organize information and activities involved in design. An entity-based integrated design model involves a number of product and process entities. Product entities and process entities describe design information and design activities, respectively. One type of relationships among entities is interaction relationships, which describe interdependencies among design information. The interaction relationships can be represented as constraints. Types of constraints include demand constraints, dependency constraints, and interaction constraints. The concepts of representing and processing demand constraints in an entity-based integrated design model are presented.

The current study examines principles to develop universal design guidelines for manufacturing information and communication devices. The study surveyed inconveniences disabled people experience in the information and communication environment with current technology and design, and suggested abbreviated universal design guidelines. Design guidelines should reduce those inconveniences detected through the task analysis and GOMS modelling of the usage by disabled people. Design and functional features of mobile phones were examined since they quickly became essential communication tools for both disabled and non-disabled people alike. Design issues were examined in controls, input methods, and output methods in terms of human factors and ergonomics. It is expected that both governments and manufacturers can save costs to produce and manufacture special assistive devices for disabled people by implementing universal design in their communication products. Since it is becoming the international trend, application of the universal design should be enforced to all communication and information devices by government for the higher quality of life for all groups of user.

설계공리는 독립공리와 정보공리로 이루어졌는데, 독립공리를 이용하면 개념설계 단계에서 기능과 구조의 관계를 고려하여 설계의 기본적인 개요을 잡는데 유용하며, 구조가 결정이 된 후에 기능요구를 잘 만족시키기 위한 설계변수들의 결정과정에서, 설계의 정보량을 최소화하는 입장에서 정보공리를 이용함으로서 설계 시에 설계공리의 적용이 가능하리라 본다. 본 연구에서는 조선분야의 설계문제에 설계공리를 적용하여 봄으로써 설계공리의 응용 가능성을 고찰하였다. Thruster의 개념설계 예제에서는 독립공리를 사용하여 기능요구와 설계변수의 분석이 어떻게 이루어지는가를 보였고, 주기관 선정 예제에서는 대안들을 선택하는 방법으로 정보공리가 효과적으로 이용될 수 있음을 보였다. 또 설계변수의 선택과 변경량이 중요한 상사설계에서도 바지선의 예를 통하여 설계공리가 유용하게 쓰일 수 있음을 보였다. 그러나 초기에 제한조건과 기능요구를 모두 파악하기 어려워 점진적이며 반복적인 설계과정을 거치는 선박과 같은 대형 구조물인 경우에는 설계공리의 적용에 한계가 있음도 파악하였다.

Ship design engineering refers to the development and design of shipbuilding architectures in a drawing which reflects all relevant manufacturing processes. This paper provides analysis methods for model-information interfaces between hull structure design and outfitting design, and a technical application for manufacturing phases reflecting the pipe support pad and angle item automatically. The existing information procedure of pipe support pad and angle system processes information using drawing without model specification. Outfitting design team directly distributes drawings to the shop floor then manual-based marking and installation work are conducted refer to the distributed drawings. As a result, this process has become time consuming and causes problems in the productivity and quality improvement due to the rework caused by omitted or incorrect marking. The pipe support pad and angle marking is a method that automatically updates model information to hull structure design using sets of data that analyse the generated model in outfitting design processes. Therefore, this approach provides an efficient solution through design references without manual activities such as a reflection of hull structure design, cutting process, numerical control work, and dimension measurement and marking. The conversion of a method from the existing procedure based on manual marking to the reflective and automatic approach would have enabled to proceed installation work without manual activities for the measurement. Therefore, this research study proposes an efficient approach using pre-data analysis of model information interfaces between design and manufacturing phases to improve productivity during construction for shipbuilding.

Sensitivity information has been used for linearization of nonlinear functions in optimization. Basically, sensitivity is a derivative of a function with respect to a design variable. Design sensitivity is repeatedly calculated in optimization. Since sensitivity calculation is extremely expensive, there are studies to directly use the sensitivity in the design process. When a small design change is required, an engineer makes design changes by considering the sensitivity information. Generally, the current process is performed one-by-one for design variables. Methods to exploit the sensitivity information are developed. When a designer wants to change multiple variables with some relationship, the directional derivative can be utilized. In this case, the first derivative can be calculated. Only small design changes can be made from the first derivatives. Orthogonal arrays can be used for moderate changes of multiple variables. Analysis of Variance is carried out to find out the regional influence of variables. A flow is developed for efficient use of the methods. A software system with the flow has been developed. The system can be easily interfaced with existing commercial systems through a file wrapping technique. The sensitivity information is calculated by finite difference method. Various examples are solved to evaluate the proposed algorithm and the software system.
