An automated process planning system for cold forging of non-axisymmetric parts of comparatively simple shape was developed in this study. Programs for the system have been written with Visual LISP in the AutoCAD using a personal computer and are composed of four main modules such as input module, shape cognition and shape expression module, material diameter determination module and process planning module. The design rules and knowledges for the system are extracted from the plasticity theories, handbook, relevant reference and empirical knowledge of field experts. Generally, in forging, only front view is needed for expression of axisymmetric parts, but non-axisymmetric parts need front and plane view. At the plane, this system cognizes the external shape of non-axisymmetric, parts - number of sides of regular polygon and radius of a circle circumscribing the polygon of n sides. At the front view, the system perceives diameter of axisymmetric portions and height of primitive geometries such as polygon, cylinder, cone, concave, convex, etc.

This paper presents an application result of on-line fault diagnosis system for glass melting furnace using a fuzzy expert system. Operators maintain the furnace using the furnace Knowledge and experience, which directly influence the furnace and glass product. Firstly, knowledge and experience is achieved and analyzed to implement the furnace Knowledge and experience into fuzzy expert system. The acquired Knowledges determined as a crisp rule or a fuzzy rule to expect its characteristics. And, a linear regression is used as the input of fuzzy rule to consider the exact knowledge of human operator. The fuzzy expert system is implemented with G2 which is an on-line expert system tool of Gensym Co. The application to a production furnace of Samsung-Corning Co. in Suwon shows successful results of proposed fuzzy expert system.

In this paper, we designed and implemented an integrated search and collaboration system. Users can search the traditional korean medicine knowledge in our system, which consists of medicinal materials, formulas, diseases, terminology, and clinical information. In general, the existing information systems providing the korean medicine knowledge do not provide the update function. Thus, it can be a problem if there are incomplete information. In order to solve this problem, our system implements the functions that users can work together to improve the knowledge. Therefore, wrong information can be updated easily so that flexible management about the korean medicine information is possible.

If you ask many Stereographers how to make a good S3D and you will get all different answers. There are several 3D knowledges and opinions that were not always in agreement. we have to choose which advice to follow and find our own way. But there will be no durable screening of S3D films without a minimal viewing comfort of all the audience whatever the differences of their vision. First of all, We always consider several factors to get an appropriate S3D shot before moving on to production. This is intended to provide a practical example on S3D film production. I hope that this article will encourage further research on this topic.

The high-rise building construction field in the urban area is short of working space because it is surrounded by adjacent buildings and nearby roads. The insufficient space causes problems of interference and conflicts in transporting materials and working at the site. These problems can be resolved partly through the proper selection and layout of temporary facilities. A method proposed in this paper supports a decision-maker to evaluate and select the alternatives of temporary facilities plans by establishing and analyzing processes and influence factors of them. Knowledges considered in planning temporary facilities layout are structurized and a program is implemented for a field manager. Case studies are performed to evaluate the feasibility and applicability of the proposed method.

Some problems with the definition, collection, organization, management and use of classics and some solutions for these aspects are presented in this study, in terms of the activation of classics department management. While trying to put these solutions together and to make some basic remedies, we lead to the following facts. First, the understanding on classics should be changed. The ideas that classics are very valuable, so they are only for preservation should be turned to that of making them actively used by the users. And policies as a result of positive interests should be established. Secondly, a written collection development policy statement should be maintained. All the regulations and policies on collection, organization, management and use of classics have to be expressed clearly in this document, in order for the positive and consistent activation of classics department. Thirdly, professional librarians who deal with classics are needed. In order for providing classics service efficiently, first of all, professional librarians who have professional knowledges on classics and are able to provide satisfactory services to their users are needed. And, Financial su n.0, pport for the classics department should be improved. At present, there are few financial su n.0, pports for the classics department in the common libraries. In this situation, it is very hard to activate the use of classics.

This paper presents an original approach for solving short-term power scheduling in extended power system with two fuels in a unit and a limited fuel using Lagrangian relaxations. The underlying model incorporates the full set of costs and constraints including setup, production, ramping, and operational status, and takes the form of a mixed integer nonlinear control problem. Moreover, the mathematical model developed includes two fuels in a unit and a limited fuel, regulation reserve requirements of prespecified group of units. Lagrangian relaxation is used to disaggregate the model by generator into separate subproblems which are then solved with a nested dynamic program including empirical knowledges. The strength of the methodology lies partially in its ability to construct good feasible solutions from information provided by the dual. Thus, the need for branch-and-bound is eliminated. In addition, the inclusion of two fuels in a unit and a limited fuel provides new insight into the limitations of current techniques. Computational experience with the proposed algorithm indicates that Problems containing up to 23 units including 8 unit used two fuels and 24 time periods can be readily solved in reasonable times. Duality gaps of less than 4％ were achieved.

Even the pharmacotherapy is more effective than placebo for the treatment of depression, the outcome of pharmacoltherapy remains unsatisfactory for many patients. Apart from side effects, there are two major limitations of antidepressant therapy. One is the delayed onset of improvement and another is partial response. In order to address these clinical dilemmas, many psychiatrists more commonly employ add-on therapy. In past, the practice of using multiple drugs to enhance treatment response was called polypharamcy, and was disparaged as poor clinical practice. However, with improved understanding of how drugs affects the central nervous system and increased communication in journals and on computer networks about the relative merits of specific combinations, the scientific basis for the combining drugs is being defined. Indeed, the use of multiple medications as a stratege to enhance response has become both acceptable and widespread now a days. It is now referred to more positively as add-on therapy, co-medication, combination therapy, or drug augmentation. Thus, as the methods of practical strategies for treatment of depression, switching classes antidepressant drugs, combination therapy, augmentation strategies and brief treatment algorithm will be presented with items of considerations. However, when combination of drugs being tried, knowledges about the action of mechanism, pharamcokinetics, and pharmacodynamics are essential to cope with the possible adversive reactions and to get the appropriate responses for the treatment of depressive symptoms.
