  • Most of us spend the greater part of our lives at the chair, but of all the man environments it is maybe the least well-explored share commitment to a cleaner and healthier environment. It has long been chairs belief that the environment is a precious gift. In case of mesh chair, because it depend upon the earth's resources to design and manufacture steel furniture products, human beings feel an abiding responsibility to act wisely in the environmental choices we make, large and small, every day. Ergonomically, it ought to do more than just sit there. It should actively intercede for the health of the person who sits in it longer than it should. Therefore, product design should be approachable to satisfaction of end-users in aspect of value engineering easy to move through analysis of cost reduction factors the purpose of this thesis is to study products for users based on office chair to development of design for office chair by analysis of manufacturing status and methods and problems in Korea through research on actual situation as well as changing process ergonomic study and design of office chair.

  • aThe terms of hard and soft as applied to wheats are descriptions of the texture of the kernel. A hard wheat kernel required greater force to cause it to disintegrate than those a soft wheat kernel. Factors than can affect the measurement of hardness outnumber those that affect hardness itself. Kernel texture is the most important single characteristic that affects the functionality of a common wheat. It affect the way in which must be tempered for milling ; the yield and the particle size, and density of flour particles ; and the end use properties in milling, breadmaking, production of soft wheat products, and noodle-making. Papers are reviewed from various sources not only hardness but flour functionality.

  • The compression strength of the corrugated fiberboard boxes is very important information to the manufacturers and the end users. The computer program being used to design the compression strength of the boxes was developed by using Korean Standards for the corrugated fiberboard box and some other data. The developed computer program could be applied to only the boxes produced according to the Korean Standards. Also this program needs to be revised continuously by the newly added and developed data.

  • A procedure of 3H-radio labeling synthesis for the dammarane triterpene glycosides of Korean ginseng was established by using the ginsenoside Rg1 as starting material. The protons in C11 and C13 of the aglycone moiety of the glycoside were exchanged with tritium by keto-enol tautomerization of 12-keto-ginsenoside Rg1 which was prepared by partial acetylation, Sarett oxidation and saponification, producing nona-acetate, nonaside Rg1. The acety1-ketone and 12-keto-derivative of ginsenotritated ketone was reduced by metallic sodium and isoproponol to produce the end product 3H-ginsenoside Rg1 with 3% radio-chemical recovery in one experiment.

  • De-manufacturing is an entire process of collecting, disassembling, reusing, refurbishing, recycling, and/or disposing products that are obsolete or un-repairable. Designing the products for inexpensive and efficient disassembly enhances the ease of de-manufacturing. Virtual disassembly addresses the difficulty and the methods to disassemble a product in design stage rather than really disassemble a product at the end of its life cycle. Based on the virtual disassembly analysis results, design will be improved for better assembling/disassembling. This paper presents a systematic virtual disassembly methodology such as disassembly relation modeling, path/sequence automatic generation and evaluation. This paper also presents a new virtual disassembly interface paradigm via virtual reality technology for disassembly simulation in virtual environment.

  • Cropping of head and tail ends of rod in wire Rolling Process is required to aviod roll damage, and prevent cobbles. In order to reduce the crop loss, the new crop control system for rotary shear of Wire rolling Process has been developed. Performance shows the developed system cut precisely within setting length. As a result, it is expected to increase the yield ratio of products about 0.2 percent and stabilize the operantional condition.

  • A on-line optimization scheme based on model in a binary distillation process is proposed. A reduced-order model utilized the concept of collocation is used as a process model and the recursive prediction error method is employed to identify the reduced-order model. The concentrations of end products are controlled by nonlinear adaptive predictive control algorithm. The objective function is constructed to find optimum operate condition for saving utility cost. The proposed optimization is scheme is tested through simulation studies in 13-staged water-methanol distillation column.

  • An ethanol tolerant mutant was selected by successive transfers of Clostridium thermohydrosulfuricum ATCC 33223 into the media with progressively higher ethanol concentrations. The growth kinetics of the mutant were characterized under various growth conditions. Physiological differences such as enhanced growth, tolerance to various solvents, alteration of the optimum temperature and the ratio of end products during fermentation were noticed in the mutant.

  • During the past few years, the productivity has been considered as one of the most important aims in developing softwares. Many practitioners and theorists are trying reuse ready made codes to increase the productivity of software development and the quality of their products. This paper introduces our experiences in developing a highly reusable class library and its reusing environment for building a database interface application. And the concepts, Structured Multi-Library and Dual Views of Class Inheritance, are also suggested, which consist our main conceptual framework in our work. Details in implementation are discussed in brief at the end.
