To provide required flow rates of cooling or circulating water properly, approach flow conditions of vertical pump systems should be in compliance with state of the art acceptance criteria. The direct inflow should be vortex free, with low pre-rotation and symmetric velocity distribution. Physical model investigations are common practice and the best tool of prediction to evaluate, to optimize and to document flow conditions inside intake structures for vertical pumping systems. Optimization steps should be accomplished with respect to installation costs and complexity on site. The report shows evaluation of various approach flow conditions inside a compact waste water pumping station. The focus is on the occurrence of free surface vortices and the evaluation of air entrainment for various water level and flow rates. The presentation of the results includes the description of the investigated intake structure, occurring flow problems and final recommendations.

In this paper, we investigate cross-platform interoperability for natural language processing (NLP) and, in particular, annotation of textual resources, with an eye toward identifying the design elements of annotation models and processes that are particularly problematic for, or amenable to, enabling seamless communication across different platforms. The study is conducted in the context of a specific annotation methodology, namely machine-assisted interactive annotation (also known as human-in-the-loop annotation). This methodology requires the ability to freely combine resources from different document repositories, access a wide array of NLP tools that automatically annotate corpora for various linguistic phenomena, and use a sophisticated annotation editor that enables interactive manual annotation coupled with on-the-fly machine learning. We consider three independently developed platforms, each of which utilizes a different model for representing annotations over text, and each of which performs a different role in the process.

The amount of Meta-data to be managed increases with development of information technology. However, when trying to integrate and share product information of heterogeneous systems within or between companies, sharing of information is impossible if product information classification systems are different. Due to the situation mentioned above, engineers judge the product information classification system and maps corresponding Meta-data for document-based sharing. Judging exponentially increasing amount of data by engineers and sharing product information using documents create great amount of time delay and errors in data handling. Therefore, construction of a system for integrated management and interoperability between product information based on semantic information similar to engineer's judgment is required. This paper proposes a methodology and necessity of a system for interoperability of product information based on semantic web, and also designs a system to integrate heterogeneous systems with different product information using rule based reasoning. This paper also suggests a system base for interoperability and integration of product information between heterogeneous systems by integrating the product information classification system semantically.

International standards claim the best possible reliability in industrial manufacturing processes. This is also essential for the application with manual applicators. The application of adhesives with manual applicators is one of the most frequently used application techniques. The range of application reaches from the building of prototypes in the automobile industry over the use in single or small-batch manufacturing up to applications in crafts enterprises. Conventional manual applicators for adhesives and sealants don't fulfill the demands in international standards for the best possible reliability. Only the worker is able to control the quality and the quantity of the bond. A velocity-controlled manual applicator solves these restrictions. Special sensors and micro controllers calculate the flow-rate, the velocity and the location of the manual applicator. This leads to stable and repeatable application processes which are claimed in international standards. The location of the bond can be compared with the nominal value, so that it is possible to check the quality of the bond during application. Furthermore there is the potential to document the data of the manufacturing process.

Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.

The document archives like official documents, books, maps and historic paper artifacts are primarily based on the organic cellulosic materials. As the passage of time, these organic cellulosic materials are slowly deteriorated by various aging factors, like light, polluted air and biological fungi. Many researchers have been carried out the examination method of deteriorating origins, the mechanism of aging hysteresis, and the preserving method of archival materials. One of the most simple and easiest ways for conservation of organic archival documents is the proper storage under environmental control. Corrugated board for archival quality container has been developed and already used in advanced country, like Japan, USA, German, UK and Europe. In case of Korea, corrugated board for archival quality container has been used a decade ago, but totally imported. This study was tried to develop the corrugated board for archival quality container. Liner and corrugated medium were specially produced and finally manufactured to E flute corrugated board. The physical and strength properties of permanent base paper and corrugated board were evaluated, and compared with imported corrugated board. 4 kinds of corrugating adhesives were considered various in order to investigate optimum adhesive for flute development between liner and corrugating medium, and evaluate adhesion strength under conditions of storage and curing temperatures.

기업 간 비즈니스 거래를 하기 위해서는 B2B(Business to Business) 기업이 지원하는 업무 프로세스에 관한 정보와 업무 정보 교환을 위해 기업의 기술적인 사항을 정의하고 거래 기업 간의 비즈니스 거래를 위하여 거래 파트너간 합의된 상호작용을 정의한 문서가 필요하다. 이러한 문서를 XML 기반의 개방형 전자상거래 프레임워크인 ebXML(electronic business XML)에서는 기업의 비즈니스 협업 능력을 정의한 전자를 협업 프로토콜 프로파일(Collaboration-Protocol Profile:CPP)이라 하고 거래 기업간의 비즈니스 협업 상호작용을 정의한 후자를 협업 프로토콜 약정서(Collaboration-Protocol Agreement:CPA) 라고 한다. 본 논문에서는 ebXML에서 거래 기업 간 상호 운용성을 증대시키는 CPP 문서를 효율적으로 저작 할 수 있는 생성기와 거래기업들의 CPP 문서들을 기본으로 상호 협업을 정의한 CPA문서를 저작할 수 있는 Composer 시스템을 설계 및 구현하였다.
