Herein we present a diagnostic paper chip that can quantitatively detect albumin without external electronic reader and dispensing apparatus. We fabricated a diagnostic paper chip device by printing wax barrier on the paper and wicking it with citrate buffer and tetrabromophenol blue to detect albumin in sample solution. The paper chip is so simple that we dropped a sample solution at sample pad and measure the ratio of two travel distances of the sample solvent and albumin under the name of retention factor. Our result confirmed that the retention factor was constant in the samples with same concentration of albumin and useful determinant for the measurement of albumin concentration. The paper chip is affordable and equipment-free, and close to ideal point-of-care test in accordance with the assured criteria, outlined by the World Health Organization. We assume that this diagnostic paper chip will expand the concept of colorimetric determination and provide a inexpensive diagnostic method to aging society and developing country.

Ever since the ISO (International Organization for Standardization) established the ISO 9000 Family standard in 1987, many countries have selected this as their national standard and have provided support for its implementation and conducted assessment activities on the results of its implementation. Likewise, certification assessment was first begun in Korea in 1994, with the result that over 7,600 certificates have been issued to domestic enterprises during the past 5 years or so. This is significant not only in the remarkable growth rate in terms of quantity but also in the fact that it has made possible the establishment of a quality system that meets international standards among Korean enterprises. In this article, it will briefly introduce the establishment and certification of the ISO quality system for those organizations that are complying with the quality system as a part of the process of strengthening their quality competitiveness. For those organizations that have already established the quality system and implemented it for years, we will show the direction for continuous quality improvement in order for these organizations not only to fulfill the requirements but to maintain the superiority of the quality system and their management quality. In addition, it will show what preparations are necessary for organizations and certification bodies in order to expand a manufacturing process-oriented quality system to one that is geared to the total management quality.

In every sectors of industry, the Business Process Reengineering(BPR) has been applied for taking competitive advantage under rapidly changing environment. A company adopting the BPR has begun to consider the introduction of Enterprise Resource Planning ERP systems. ERP systems can integrates many core activities of business, such as manufacturing management, human resource management, financial management, supply chain management by applying the best practices to facilitate a rapid decision-making, cost reductions, and organizational control. Unfortunately, however, many tentative risk factors are existed through each phase of the introduction of ERP systems. As a result, it can bring an enormous benefits to a company or it can be a disastrous for organization. Therefore, two critical questions regarding the introduction of ERP systems should be analyzed before actual introduction has happened. They are "how can ERP systems be introduced successfully\ulcorner" and "what are the critical success factors for each phase of introduction of ERP systems\ulcorner". Through this research, We studied and analyzed the characteristics of critical success factors requiring at each phase of the introduction of ERP systems by applying the questionnaire survey method. Finally, we suggest the list of barriers and critical success factors for each phase of introduction of ERP systems.tion of ERP systems.

According to the rapid development of science technologies, a life and development cycle of products are getting shorter and structures and functions become more complex so that the reliability requirement of customers is getting greater for components in the products. However, most domestic mechanical components are manufactured by small and medium-sized companies, who are manufacturing in poor economic and technical condition. Because of this, assessment technologies and equipment to predict and guarantee the reliability are very weak. For this reason, it is the fact that many customers neglect the domestic mechanical components which fail to win the reliability. Korean government has been trying to eliminate the problem by establishing 18 reliability assessment centers in 2000 and performing R-Mark certification promotion and constructions of the foundation for reliability assessment to rebuild the reliability on the domestic components and materials. Korea Institute of Machinery and Materials has been designated as a supervising organization for reliability assessment in the machinery filed for 5 years. In this paper, we would like to introduce effective and systematized 12 steps of reliability substantiation test on mechanical components with know-how we achieved during the period.

In recent years there has been an increasing amount of attention paid to outosourcing of information systems (IS) functions in organizations. The changing and more strategic role of outsourcing in business firms has been given much coverage in academic and trade publications. Trying to remain competitive and up-to-date in the rapidly developing world of computer technology is becoming a financial burden to many organizations in fields such as banking and financial services, health care, and manufacturing. Hiring outsiders to handle part or even all of its information services helps an organization provide better services and maintain a competitive advantage. This paper attempts to provide a benchmark of current IS outsourcing utilization in Korea. A detailed descriptive analysis of survey responses from 78 Korean companies indicates the usage, length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced. The study also analyzes the effects (strategic, economic, and technological) of IS outsourcing with respect to the length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced As a result of the analysis there are significant differences in the strategic, economic and technological effects of IS outsourcing with respect to the expenditure of outsourcing, kinds of IS functions being outsourced and firm size.

In most recent years, the business competition has spreads over all fields of corporations and their management area regardless of time and place, which makes the survival environment of each enterprise fiercer. In order to secure a high position in the competitive market, the various firms has implemented many methods related to price, quality, and service efficiency. However, the implementation with only low price or high quality might be helpless to hold a high position in modem market. Moreover more attention should be paid to the internal business processes of an organization. Therefore, a new and different method should be searched or developed in order to win the competitive power among other enterprises. This research will focus on the improvement of the business processes within the non-manufacturing industry by applying Lean Six Sigma methodology. DMAIC method will be applied to improve the inbound and outbound logistics processes, manage the inbound and outbound vehicles, and control the receiving and shipping activities.

Recently, object-oriented techniques have been used more and more for developments of an information system. But, established object-oriented methodologies are hard to express a business process of various abstract degrees in the analysis level and independent components of the system. They have difficulties in developing a large-scale information system of manufacturing industry such as PDM and CIM. This paper proposes an information system development methodology that imports the object-oriented IDEF0 (OOIDEF0) function model in analysis level. This methodology is made up of requirements gathering, system analysis, system design, and implementation. In requirements gathering level, organization diagram and interview technique are used for input data of OOIDEF0 function model. The OOIDEF0 function model, the interface model and function descriptions are made out in analysis level. Information objects and implementation objects are designed on the basis of the OOIDEF0 function model in design level. The database is built and programming is accomplished in implementation level. In order to prove the consistency and efficiency of the proposed methodology, the PDM system for ship production is modeled and prototyped.

Background: The success of an injury intervention program can be measured by the proportion of successful return to work (RTW). This study examined factors of successful return to employment among workers suffering from work-related injuries. Methods: Data were obtained from the Social Security Organization, Malaysia database consisting of 10,049 RTW program participants in 2010-2014. The dependent variable was the RTW outcome which consisted of RTW with same employer, RTW with new employer or unsuccessful return. Multinomial logistic regression was performed to test the likelihood of successful return with same employer and new employer against unsuccessful return. Results: Overall, 65.3% of injured workers were successfully returned to employment, 52.8% to the same employer and 12.5% to new employer. Employer interest; motivation; age 30-49 years; intervention less than 9 months; occupational disease; injuries in the lower limbs, upper limbs, and general injuries; and working in the manufacturing, services, and electrical/electronics were associated with returning to work with the same employer against unsuccessful return. Male, employer interest, motivation, age 49 years or younger, intervention less than 6 months, occupational disease, injuries in the upper limbs and services sector of employment were associated with returning to new employer against unsuccessful return. Conclusion: There is a need to strengthen employer commitment for early and intensified intervention that will lead to improvement in the RTW outcome.

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 - This research explores the impacts of third-party logistics (3PLs) within the aircraft Maintenance, Repair and Overhaul (MRO) industry in the United Arab Emirates (UAE) to explore the role of collaborative relationships for improving outsourcing. Globalization and time based competition have changed business environments and challenged the conventional management strategies that are related to core competencies and operational models. Organizations are forced to devise innovative practices in which logistics outsourcing to 3PLs offers significant advantages. Research design, data, and methodology - This case study was conducted within a leading global aircraft MRO organization whose reach spans across Europe, the Middle East, Asia and the Americas. The methods used face to face semi-structured interviews, validated through further focus group discussions. Results - These findings highlight the effectiveness of collaborative relationships on their role to improve outsourcing and also demonstrated that MROs gain several advantages from 3PL arrangements. However, any gaps in outsourcing management elevates potential risks to organizations as well, which could result in reputational, operational and financial losses. Conclusions - Although generalizability is not possible due to the case study approach, generality suggests that in order to reduce reputational, operational and financial risks, enhanced collaboration with 3PLs is recommended to optimize outsourcing arrangements.
