Sheet metal forming process is a non-linearity problem which Is affected by various process variables, such as geometric shape of punch and die, frictional characteristic, etc.. Therefore, the knowledge of the influence of the process variables is needed in the design of sheet metal working processes. In this paper, deep drawing tests for blank holding force, punch speed and lubrication between sheet material and tool were carried out to investigate the influence upon sheet formability. Experimental results were discussed about the defects on the deformation behaviors during the forming process.

Absorption systems require a heat source for working but they have a great merit in that relatively low-temperature and low-quality types of thermal energy such as solar heat and exhaust heat can be effectively utilized as heat source. However details research related to absorbers which have a great effect on performances has been rarely done and thus there has been a strong hope for positive developments to improve their efficiencies. This paper describes absorption experiments made with different inside tube diameters and shapes. The purpose of this study is to acquire basic knowledge about heat and mass transfer in a falling film type absorber with vertical inner tubes. Heat and mass transfer were measured for water vapor absorption into a water/LiBr solution flowing down an absorber of vertical inner tubes. As a result absorption acceleration tube compares bare tube and heat transfer improved by order of insert spring tube corrugated tube grooved tube. And the acceleration that is good provided in inserting spring tube for both sides of heat and mass transfer.

First, I'd like to express my great respect to the highly developed environment-friendly and organic agriculture in South Korea, especially in this region of Yangpyong. I've heard that rural farmers and city people cooperated together to develop the environment-friendly agriculture in Yangpyong. I believe Japanese farmers and people can learn a lot from the experience of your people. We'd like to exchange our knowledge and experience to develop environment-friendly and organic agriculture in both countries, for we share a lot in common. In this paper, I'd like to introduce how the Japanese have been developing organic and environment-friendly agriculture, and how we are working with the official organic standard and building the social structure to encourage the overall development of organic and environment-friendly agriculture.

High Touch product is characterized by shorter life cycle together with specification/integration of existing function in order to capitalize the rapidly emerging high technology. R & D strategy for a development of High Touch product generally emphasizes two aspects ; Industrial Design (ID) and Ergonomic Design (ED). However, working knowledge on ED of a systematic identification of potential High Touch products is not readily available. The purpose of this study was three-folded : (1) To emphasize the fact that greater efforts should be geared to ED in High Touch design ; (2) To develop an ergonomic approach based on analysis of implicit human needs that identifies potential area of High Touch ; (3) To bubble with new and probable High Touch products in home electronics that actually demonstrate the validity of this study.

Business Rules are formal statements about the data and processes of an enterprise. They present projections of the organization's constraints and ways of working on their supporting information systems. Therefore, their collection, structuring and organization should be central activities within information systems. In an enterprise, business rules are used to represent certain aspects of a business domain (static rules) or business policy (dynamic rules). Hence, regarding problem domains in the organization, business rules are classified into two groups: static and dynamic business rules. The paper introduces a new concept of business rules, Extended Dynamic Business Rule (EDBR) which contains the results of the occurrence of business rule's action. The focus of this paper is in the organizing, defining and modeling of such business rules using Mineau's approach. Mineau's approach is an extension of Sowa's Conceptual Graph theory.

In this paper, on the assumption that the dispute about the identity of Oriental Medicine(OM) will finally act as an developmental element of Oriental Medicine otherwise total Korean Medicine, at first we think about what are he meaning of identity and it's essential elements, and search how to establish the standard of the identity of Oriental Medicine. From this working, the direction of the research in the Oriental Medical Classics that is one of the detail field in OM will be drawn out. The identity of Oriental Medicine must be decided according to what is the mission or existence value contributing for Korean Society, not to the form of materiality or immateriality. The core of the identity of Oriental Medical Classics is relevant to being a help to other research fields through reinterpreting the Classics. And the most important issue of research are the analysis of thinking pattern In OM, and systematization of OM knowledge and information.

In nuclear power plants, workers are reluctant of works in steam generator because of the high radiation environment and limited working space. It is strongly recommended that the examination and maintenance works be done by an automatic system for the protection of the operator from the radiation exposure. In this paper, it is proposed a new approach to the development of the automatic vision system to examine and repair the steam generator tubes at remote distance. Digital signal processors are used in implementing real time recognition and examination of steam generator holes in the proposed vision system. Performance of proposed digital vision system is illustrated by experiment for similar steam generator model.

The sealing technique is widely used for repairing the cracks on the surface of concrete and preventing their expansion in the future. However, it is difficult to ensure the safety of the workers when sealing large structures in inconvenient working environments. This paper presents the development of a sealing robot system to seal various shapes of concrete surface in rough conditions for a long time. If the robot can maintain the desired contact force, the cracks can be completely sealed. An impedance force tracking controller with slope estimator is proposed to calculate the surface slope in real time using the robot position. It predicts the next point in order to prevent the robot from disengaging from the contact surface owing to quick slope changes. The proposed method has been verified by experimental results.
