After establishing the EIA(Environmental Impact Assessment) act in the Federal Republic of Germany there still remain methodical and substantial deficits. So nearly every environmental impact study went to be a matter of experiments. The requirement for standardization of data sampling and evaluation has permanently been increasing. This is meant to ensure quality standards for the assessment of environmental impacts as well as to maintain reliability required by the projecting company. Such a harmonization is of special importance because of the strongly accelerated expansion of traffic infrastructure caused by the reunification of Germany. That is why the guideline "EIA carried out" for the German Railways company is in process of development This guideline, focussing on practical demands, comprises impacts of railways, adequate sets of indicators, feasible tools for the prognosis and evaluation of environmental reactions. "EIA carried out" will be introduced not only as a manual but also through workshops and pilot studies.

Nowadays, because of the frequent market change and variable customer's requirements, product's life-circle is becoming shorter. So, automobile companies are forced to rapidly develop new products and efficiently reduce both manufacturing lead time and cost, with the world level quality. Among them, Press Die is not only just a bottle neck but also an important resource exerting certain effect in quality of car body appearance. Since 2000, due to efforts to reduce the time of design phase, many companies have used 3D design methods. Actually the method didn't reduce the period of design because the company didn't develop the best practice. This paper wish to solve this problem by modular based hybrid dies template.

Herbal medicine is the use of medicinal plants for prevention and treatment of diseases: it ranges from traditional and popular medicines of every country to the use of standardized and tritated herbal extracts. Generally cultural rootedness enduring and widespread use in a traditional medical system may indicate safety, but also efficacy of treatments, especially in herbal medicine where tradition is almost completely based on remedies containing active principles at very low and ultra low concentrations or relying on magical-energetic principles. The efficacy and safety assessments of medicines, whether modern or herbal, invariably encounter challenges or problems during the course of pre-clinical and clinical research. Some of the challenges in evidence-based herbal medicinal research are unique, and the researcher must be cognizant of them in order to safeguard the quality of the data obtained. Key challenges are: the quality of raw materials; appropriateness of biological/pharmacological activity assessment methodology, and data interpretation; standardization methodology; pharmacokinetics and bioavailability of active constituents and metabolites; clinical dosage formulation/production; and clinical study designs and outcome measures.

Objectives: This study has been done to make sure the Gypsum's standardization in medical use. Gypsum has a quality for removing pathogenic heat from the stomach meridian function and headache. Methods: I studied the herbalogical Gypsum and compared its' compositions and character before and after high temperature burning. Results: Gypsum and Lishi(理石) are the sulfate which is made of $CaSO_4{\cdot}2H_2O$, Feldspar is a Calcite, Hanshuishi(寒水石) and Ningshuishi(凝水石) are not a Gypsum but a Magnesium Sulfate($MgSO_4$) and Kalium Sulfate($K_2SO_4$). Conclusion: Real Gypsum is supposed to be Yiong cheng${\setminus}$(應城) Gypsum. Chemical edible Gypsum isn't appropriated to be used in medicine.

The production, processing, sale and service of food materials are not subject to attainment via a single country. In accordance with internationalization of the world, issues related to food safety have emerged as critical international concerns and they are closely associated with the health and interest of domestic consumers, producers, manufacturers, and distributors. As a third party certification standards, ISO 22000 is in progress International Organization for Standardization(ISO) and the Draft International Standard(DIS) has already been presented on December 2004. The purpose of this study is to analyze the international standards, guidelines and legislation in regard of Food Safety Management System(FSMS) including ISO 9001, Hazard Analysis Critical Control Point(HACCP) and Product Liability(PL) so as to present Korean-model Food Safety Management System requirements and system establishment model.

Software Engineering covers techniques, tools, and methodologies needed to develop, acquire, and manage software in high quality, using appropriate resources. Therefore it can be said that the administration target of software engineering activities is the pursuit of high productivity for production of software in good quality. To do this, they should establish the engineering principle based on engineering theory and concept, and form the effective environment of engineering technology through improving development methods/methodology and tools of software engineering. In addition several guidances related to information system planning, acquisition, development, management, maintenance, and evaluation, etc. must be invented on the basis of software engineering to encourage efficiency of public information business yearly increasing fastand to make sure compatibility and interoperability.

Coiling processes of filaments need precise work and standardization. It is important to maintain equal pitch of filaments. Uniform pitch of filaments is one of the dominant elements of life time and efficiency of bulbs. First coiling process of filament wires is modeled by nonlinear contact problem between filaments and mandrel. Analysis of coiling process using finite element method is conducted to consider manufacturing parameters and pitch distance is calculated under the given conditions. Also image detecting system is developed to inspect uniformity of pitch. This system will be used to inspect quality of filaments during coiling processes.

Kampilla is an important herbal drug of indigenous system of medicine. Fruit dust of Mallotus philippensis Muell-Arg constitutes the genuine drug Kampilla. However, due to limited distribution of this plant and its high medicinal value, the drug is heavily adulterated with the cheaper substances. Hence the present study was undertaken to evaluate both the authentic and market samples. The drug consists of resin glands and trichomes. Resin glands are lined by a delicate yellowish thin membrane and bear a pore at the tip. Quantitative standards of the drug powder showed 82.50% yield in total ash while alcohol soluble extract of market and authentic sample exhibit 0.97% and 3.458% respectively. The main adulterant noticed in the market sample is brick powder. Simple methods are suggested to identify the genuine drug.

An automation process of filter unit is presented for the application of the assembling procedure and dry furnace work. By that automation procedure, it is expected to enhance working environment such as reducing laboring load, harmful gas, and burning scald. Furthermore, this automation process also minimizes via standardization of manufacturing process so that it may increase productivity and reliability. An automation process of filter unit is presented for the application of the assembling procedure and dry furnace work. Filter automation process also gives a good quality and productivity by simplifying to only one line from the complicated process such as filter cutting$\rightarrow$ adhering$\rightarrow$fabricating in a very small space. It is found that a new conceptual design of dry furnace shows the better quality like uniform heat distribution compared to the conventional design. It is also found that the present design gives a better working environment by adding cooling system.

The International Lubricant Standardization and Approval Committee (ILSAC) GF-3 passenger car engine oil specification has been introduced commercially in July 2001. The new specification oil provides superior performance in terms of fuel economy, control of high temperature deposits, and oil consumption. These enhanced performances of GF-3 engine oil need high quality base oil as well as a better additive system. In this paper, the effect of base oil on various performances of ILSAC GF-3 engine oil was investigated. From the GF-3 sequence engine tests, Group III base oil shows better performance in fuel economy retention, oxidation and varnish control than combination of group III and group II or group III and group 1.
