Current food-traceability platforms suffer from problems such as inconsistent traceability standards, a lack of public credibility, and slow access to data. In this work, a combined code and identification method was designed that can achieve more secure product traceability using the dual anti-counterfeiting technology of a QR code and a hidden code. When the QR code is blurry, the hidden code can still be used to effectively identify food information. Based on this combined code, a food-safety traceability platform was developed. The platform follows unified encoding standards and provides standardized interfaces. Based on this innovation, the platform not only can serve individual food-traceability systems development, but also connect existing traceability systems. These will help to solve the problems such as non-standard traceability content, inconsistent processes, and incompatible system software. The experimental results show that the combined code has higher accuracy. The food-safety traceability platform based on the combined code improves the safety of the traceability process and the integrity of the traceability information. The innovation of this paper is invoking the combined code united the QR code's rapidity and the hidden code's reliability, developing a platform that uses a unified coding standard and provides a standardized interface to resolve the differences between multi-food-traceability systems. Among similar systems, it is the only one that has been connected to the national QR code identification platform. The project has made profits and has significant economic and social benefits.

The efficient test tool is indispensable to the test driven development. The test tool is very helpful to get the advantage of the test driven development. Many traditional automation test tool does not support standard script language and are not suitable to unit test. In traditional unit test tool, a code for the test is added at the source code. Such method makes the complexity of a source code and has a problem which must modify many part of the source code when the test case is changed. In this paper, we present a design technique of a flexible unit testing tool which makes a developer can modify easily the test case by using the standard java script in test driven development. We implement the test tool by this design technique to verify the availability of this technique.

In our domestic software industries, it is focused on such a high quality development/ testing process, maturity measurement, and so on. But the real industrial fields are still working on a code-centric development. Most of the existing legacy systems did not keep the design and highly increased the code complexity with more patching of the original codes. To solve this problem, we adopt a code visualization technique which is important to reduce the code complexity among modules. To do this, we suggest a tool chaining method based on the existing open source software tools, which extends NIPA's Software Visualization techniques applied to procedural languages. In addition, it should be refactored to fix bad couplings of the quality measurement indicators within the code visualization. As a result, we can apply reverse engineering to the legacy code, that is, from programming via model to architecture, and then make high quality software with this approach.

By bond mechanism between the prestressing strand and the concrete surrounding it, the effective force of prestressing must be transferred to the concrete entirely. The distance required to transfer the effective force of prestressing is called the transfer length, and the development length is the bond length required to anchor the strand as it resists external loads on the member. Transfer length was determined from the concrete strain profile at the level of the strands at transfer and development length was determined from various external loading lengths and compared with current code equation. Through the test results, bond failure is predicted based on the distress caused by cracks when they propagate within the transfer zone of prestressing strand. The current code equation was found to be conservative in comparison with the measured value.

Objective: This study examined the code of ethics, which offers guidelines for early childhood teachers' ethical decisions and practices. Results and Conclusion: In the second section of this paper, the meaning of the code of ethics is reviewed. The issues of the code of ethics are also investigated to resolve moral and ethical dilemmas and to maintain high standards of professional conduct in early childhood care and education. In the third section of this paper, a comparison of the ethical codes in South Korea, Japan, the United Kingdom, and the United States is conducted. Based on the results raised in relation to the code of ethics principles and the results of comparing domestic and international ethics codes, the fourth section of this paper focuses on three topics in the current and future direction of the Korean code of ethics: (a) concreteness and clarity, (b) switching from the viewpoint of least harm to the viewpoint of maximum benefit, and (c) the range of benefits of the code of ethics. Then, including the existence of the last two codes of ethics, we discuss the direction of future difficulties currently associated with the situation in Korea.

Component-based development leverages software reusability and reduces development costs. Enterprise JavaBeans (EJB) is a component model developed to reduce the complexity of software development and to facilitate reuse of components. However, EJB does not support component assembly by a plug-and-play technique due to the hard-wired composition at the code level. To cope with this problem, an architecture for EJB component assembly is defined at the abstract level and the inconsistency between the system architecture and its implementation must be eliminated at the implementation level. We propose a component-based application development tool named the COBALT assembler that supports the design and implementation of EJB component assembly by a plug-and-play technique based on the architecture style. The system architecture is first defined by the Architecture Description Language (ADL). The wrapper code and glue code are then generated for the assembly. After the consistency between the architecture and its implementation is checked, the assembled EJB components are deployed in an application server as a new composite component. We use the COBALT assembler for a shopping mall system and demonstrate that it can promote component reuse and leverage the system maintainability.

In Korea, we still use function point based cost estimations for software size and cost of a project. The current problem is that we make difficultly calculating function points with requirements and also have less accurate. That is, it is difficult for non-experts to analyze requirements and calculate function point values with them, and even experts often derive different function points. In addition, all stakeholders strongly make the validity and accuracy of the function point values of the project before /after the development is completed. There are methods for performing function point analysis using source code [1][2][3][4] and some researchers [5][6][7] attempt empirical verification of function points about the estimated cost. There is no research on automatic cost validation with source code after the final development is completed. In this paper, we propose automatically how to calculate Function Points based on natural language requirements before development and prove FP calculation based on the final source code after development. We expect validation by comparing the function scores calculated by forward engineering and reverse engineering methods.
