An international standard for the product model data, STEP, and a standard for the distributed object technology, CORBA, will play a very important role in the future manufacturing environment. These two technologies provide background for the sharing of product data and the integration of applications on the network. This paper describes a prototype CAD/CAE environment that is integrated on the network by STEP and CORBA. Several application servers and client software were developed to verify the proposed concept. The present CAD/CAE environments are composed of several individual software components which are not tightly integrated. They also do not utilize the rapidly expanding network and object technologies for the collaboration in the product design process. In the design process in a large organization, sharing of application resources, design data and analysis data through the network will greatly enhance the productivity. The integration between applications can be supported by two key technologies, CORBA(Common Object Request Broker Architecture) and STEP(Standard for the Exchange of Product Model Bata). The CORBA provides interoperability between applications on different machines in heterogeneous distributed environments and seamlessly interconnects distributed object systems. Moreover, if all the data in the CAD/CAE environment are based on the STEP, then we can exclude all the data conversion problems between the application systems.

Purpose In this study, the relationships among environmental information exchange with suppliers(EIES), green collaboration with suppliers, green learning by environmental information, the adoption of green supply-chain management techniques(AGSMT) (i.e., the green purchasing, product design and production, and the recovery of extra facilities and inventories), environmental performance, and the organizational performance of a firm were empirically investigated. Design/methodology/approach Data for this study were drawn from a survey of the current status of EIES levels and AGSMT usage observed in Korean manufacturing firms. In total, 500 organizations were randomly selected from a population of about 1,000 firms that are listed on the Korean stock market. In order to collect empirical data, this research administered questionnaires with the sample firms. Only chief production executives were selected as respondents. A questionnaire with a cover letter was mailed to each respondent. The survey was conducted during a 3-month period between March 2015 and June 2015. Finally, 78 valid data of the sample firms were collected. Findings The results of this study showed that EIES positively affects the green corporation and learning. According to the results, it was observed that both green corporation and green learning have a positive impact on the levels of AGSMT(i.e., the green purchasing, product design and production). It was also demonstrated that AGSMT has a direct positive impact on environmental performance. In examining the effects of environmental performance on the organizational performance of a firm, significant impact was found.

In injection molding industries, CAE analyses are generally used to find out problems predicted during the process of manufacturing. The results of CAE analyses consist of much in formation such as meshes and stress, so that the size of data is pretty large. To reduce the size of the data and to make it easy to share, the CAE result to JT translator is proposed in this paper. The translator consists of three modules to translate CAE result to JT format; Extracting module gets ASCII data of product shape and the result values of CAE analysis. Sorting module and mapping module make an element data set and JT file with the data extracted from Extracting module respectively. To the JT files, engineers are able to append product properties and their comments, so that they can share the whole history of the analysis process. In addition, our case study shows that the size of JT format is reduced by almost 90% of its original data format.

In recent years, firm performance has been a topic that attracts many researchers. It is extremely important to identify the factors that change firm performance. In the current trend of competition and integration, foreign ownership, product market competition is found to reduce agency costs and impact firm performance. The purpose of this research is to investigate the relationship between foreign ownership, product market competition, and firm performance. Our research using a quantile regression model, through panel data of 290 companies listed on the Vietnam stock exchange (include Ho Chi Minh and Hanoi stock exchanges) from 2017 to 2019 that was collected by Thomson - Reuters DataStream has shown that foreign ownership and product market competition have a positive impact on Tobin's Q but are not statistically significant with ROA. Critically, our quantile regression results suppose foreign ownership, product market competition have a significantly larger positive impact in high-performing firms relative to low-performing firms. The results help propose solutions to planners and managers to change foreign ownership and product market competition to increase business performance. Besides, through quantile regression analysis, managers need to pay attention to the impact on foreign ownership, product market competition; there will be a difference between high-performing firms relative to low-performing firms.

It is not possible to exchange parametric information of CAD models based on the current version of STEP (Standard for the Exchange of Product model data). The designer intents are lost during the transfer of CAD models. To resolve this problem, the macro-parametric approach had been proposed. To enable this approach, a set of standard modeling commands has been defined. Errors or missing elements of the standard modeling commands can be discovered by implementing macro-parametric translators. But there is a limit to discover problems only by using translators. This paper proposes a method to verify the standard modeling commands by implementing a geometric modeler. First, each argument of a modeling command is verified. Second, the set of the standard modeling commands is applied to geometric modeling of commercially available product parts. For the geometric modeling, nine test models have been selected.

In this research we have developed a prototype which manages a product structure and configuration of a product under distributed heterogeneous computing environments. First, the data schema for product structure and configuration which can represent options and effectivity is proposed. Second, a technique to use JAVA and CORBA is suggested for the exchange of product structure among multiple servers in CITIS environments. Functions of the prototype related to option-based product structure are described to help readers' understanding.

국내 데이터 거래시장은 구매데이터의 불합리한 가격책정이 데이터 거래 시의 주요 애로사항으로 지속적으로 언급되고 있다. 이는 상품정보 및 사용경험 부족으로 인해 데이터상품의 가치를 제대로 평가할 수 없는데서 발생한 문제로, 데이터 거래소는 거래활성화를 위해 가격 외에 수요자가 데이터상품의 가치를 종합적으로 판단할 수 있는 정보 제공이 필요하다. 데이터 가치평가에 주로 적용되는 원가기반, 수익기반, 시장기반 평가방법은 공급자 관점에서의 가치평가결과인 가격정보만 수요자와 공유가능하기 때문에 거래 및 유통을 활성화하기 위한 데이터가치평가방법으로는 부족한 점이 있다. 본 논문은 데이터거래 이해관계자(거래소, 공급자, 수요자)가 공통된 시각으로 데이터상품의 가치를 판단하고 공유할 수 있는 측정가능한 가치평가방법을 개발하는 것을 목표로 한다. 이를 위해 해외 데이터거래소 및 관련 연구에서 중요하게 생각하고 있는 데이터상품의 가치동인을 파악하고, 가치동인별로 정량적 측정이 가능한 평가방식을 도출하였다. 또한, 거래용 데이터상품을 활용하여 평점표 형식의 평가기준을 개발하고, 상대적 가치비교가 가능하도록 계층화분석(AHP)을 통해 가치평가지수를 개발하였다. 실제 데이터상품에 평가기준을 적용할 결과, 개별 데이터상품의 특성에 따라 가치평가값이 차별화됨에 따라 가치비교도구로 활용가능함을 알 수 있었다.

Better understanding and sharing information are getting important to manage interdisciplinary product development team in a globally-distributed company. This study proposes a solution to implement RPD(Rapid Product Development) system for the distributed development teams using SOAP(Simple Object Access Protocol). And a new approach is introduced for the better understanding of product geometry among the development members in different place and the easy sharing of product information. An application example shows that SOAP operates in distributed environment more efficiently than other RPC(Remote Procedure Call) techniques and it does not respond sensitively to firewall. And SOAP is an excellent RPC and messaging technique to exchange structured data. Procedures developed with use of SOAP are worked together with web, and users can use remote services as an application program in their local computer.
