The purpose of this study was to derive practical improvement measures for the food traceability system that could improve food reliability and secure food safety. To this, in our survey May-June, 2019, 567 adult males and females were analyzed for recognition and experience of the food traceability system, measures to improve the system, and intention to make additional payments to improve the system. In the case of a food safety accident, 2.54 of 5 points were given on if the food was recalled or not. Approximately 77.4 percent of the respondents had never seen indication of a food traceability system, and approximately 93.8 percent had no access to, or experience with, using the system. Most respondents said that the food traceability system should be applied to items that need to be applied. As the volume of data that is recorded and managed by the government is recognized as high, improvement is needed. Finally, it was analyzed that the company intends to pay an additional 1.34% on average to expand its food traceability system. A more sophisticated cost analysis is needed to apply the improvements proposed to complement the plans that are acceptable to consumers and the industry.

Food traceability (FT) is being developed while food traceability system (FTS) has become the hot topic for the food safety of the food supply chain (FSC), government regulations, and customer’s satisfaction. This survey explored the Korean consumer’s awareness, preferred information, and willingness to pay for the traceability of processed food. 35.2% of the respondents were not aware of FT whereas 77.5% did not know about FTS. The customer’s perception on the purpose of FT was as a consumer's right to know (51.8%), rather than as one enhancing food safety. The customers’ awareness of FT on processed and functional food was lower than that on agricultural, livestock, and fisheries products. The important stage of FSC that the consumers perceive was manufacturing and importing (51.5%), and the preferred information was related with raw materials. Only 7.2% of the respondents perceived FT as food safety-related certifications, which is much lower than HACCP (62.9%) and GMP (17.6%). The consumers had willingness to pay for FT at a premium of 5-10% higher than the regular price. Consumers are paying attention to food safety and quality but they are still unfamiliar with FT. Stakeholders in FSC should work together to increase consumer awareness of FT/FTS and improve consumers’ behavior.

Certification labeling is a system which confirms the quality and appropriateness of pr oducts according to the standard set. It is usually evaluated by the third party to assure being reliability. Certification labeling can be used as one of the important sources of i nformation when consumers evaluate the products. Especially, certification labeling gi ves customers trust and confidence about products because the label can be the signali ng that the quality of the products is good. Although certification labeling influences p urchase decision making, many consumers do not trust the labels because of insufficie nt information of certification and distrust in the certifications. As consumers are becoming increasingly concerned about environment and wellbeing, manufacturers are turning a convention product into the production of a sustain able product. Sustainable certification can be environmental cues to evaluate a sustain able product based on the categorization inference. The aim of this research is the inte raction effect among sustainable cues on purchase intention. Consumers tend to perceive organic label of products as high-price. Thus, although they concern environment and well-being, they tend to purchase conventional products more than an organic product. In addition, an organic label can have a positive influence on perceived risk, and then perceived risk may affect purchase intention. However, the product with organic label including traceability may have a negative impact on perceived risk. Therefore, perceived risk can mediate the relationship between the interaction between organic label of products and traceability and purchase intention.

Now days, customer’s health awareness is of extreme significance. Food can become contaminated at any point during production, preparation and distribution. Therefore, it is of key importance for the perishable food supply chain to monitor the food quality and safety. Traceability system offers complete food information and therefore, it guarantees food quality and safety. The current study postulates a low cost IoT-based traceability system that utilized RFID and smartphone-based sensors. The RFID handheld reader based on smartphone is utilized to track and trace the product. In addition the smartphone-based sensor is used to measure temperature, humidity, and location during storage and transportation. The proposed system was verified for kimchi supply chain in Korea, and revealed significant benefits to managers as well as customers by providing the real-time product information, location as well as complete temperature and humidity history. The results displayed that compared to the traditional methods, the proposed system is capable of tracking products as well as processing an immense input of data efficiently and effectively.

This paper presents the case study of the Tuscan growers pasta, an example of linkage between people, territory, environment and food. The use of new technologies for agronomic management, cultivation protocols, and a food supply chain agreement guarantee high quality, traceability and sustainability from field to package, representing an innovative marketing strategy.

Concern about food safety among consumers is very high at the moment, because many problems related to food safety have occurred, such as Bovine Spongiform Encephalopathy (BSE). To improve consumers’ reliability about food safety issue, government in every country have tried to set various food policy, and the Korean government has also tried to set consumers at ease about their diet, for instance, food traceability system. The aim of this study is to define consumer perceptions and intention to participation for solar salt traceability system. As the results, consumers generally have positive perception about solar salt traceability system, and the study identifies that attitude, reliability and availability significantly influence intention to participation for solar salt traceability system.

The environment and requirements of modern war fields have been affected and thus changed by a variety of issues. To this end, the development of safety-critical weapon systems frequently need to meet those changes even in the operational phase. The necessity of the changes may be due to the preparation for mass-production or the request originated from the user military forces. To meet such a need can be even tougher in the development of safety-critical weapon systems since the integration of the requirements for both systems design and systems safety would make it troublesome. To handel the matter in this paper, utilization of architecture DB is proposed. Specifically, the situation in demand has first been analyzed and then a problem-solving process to accommodate the design changes has been constructed. In doing so, the concept of the aforementioned integration is particularly focused on the functional architecture, which could be a core concept of our approach to solving the problem. The result of a case study demonstrating the method studied using a computer-aided systems engineering tool is also presented.

In modern systems design and development, one of the key issues is considered to be related with how to reflect faithfully the stakeholder requirements including customer requirements therein, thereby successfully implementing the system functions derived from the requirements. On the other hand, the issue of safety management is also becoming greatly important these days, particularly in the operational phase of the systems under development. An approach to safety management can be based on the use of the failure mode effect and analysis (FMEA), which has been a core method adopted in automotive industry to reduce the potential failure. The fact that a successful development of cars needs to consider both the complexity and failure throughout the whole life cycle calls for the necessity of applying the systems engineering (SE) process. To meet such a need, in this paper a method of FMEA is developed based on the SE concept. To do so, a process model is derived first in order to identify the required activities that must be satisfied in automotive design while reducing the possibility of failure. Specifically, the stakeholder requirements were analyzed first to derive a set of functions, which subsequentially leads to the task of identifying necessary HW/SW components. Then the derived functions were allocated to appropriate HW/SW components. During this design process, the traceability between the functions and HW/SW components were generated. The traceability can play a key role when FMEA is performed to predict the potential failure that can be described with the routes from the components through the linked functions. As a case study, the developed process model has been applied in a project carried out in practice. The results turned out to demonstrate the usefulness of the approach.

Facing a number of global food-related accidents, the concept and system for food traceability have been designed and introduced in many countries to manage the food-safety risks. To connect and harmonize the various food traceability-information in food traceability system according to the food supply chain, the coding system of identification-number for food-traceability has to be standardized. The GTIN (Global Trade Item Number) barcode system which has been globally standardized and implemented, is reviewed with the mandatory food-labeling regulation in expiration date of processed foods. The integration of GTIN-13 bar-code system for food-traceability is a crucial factor to expand its function in the food-related industrial areas. In this literature, the standard coding system of identification-number for food-traceability is proposed with 20 digit coding number which is combined with GTIN- 13 bar-code (13 digit), expiration date (6 digit), and additional classification code (1 digit). This proposed standard coding system for identification-number has a several advantages in application for prohibiting the sale of hazard goods, food-recall, and inquiring food traceability-information. And also, this proposed coding system could enhance the food traceability system by communicating and harmonizing the information with the national network such as UNI-PASS and electronic Tax-invoice system. For the global application, the identification-number for food-traceability needs to be cooperated with the upcoming global standards such as GTIN-128 bar-code and GS1 DataBar.

It is well known that the test and evaluation plan (TEP) is very crucial in the successful development of safety-critical systems. As such, this paper discusses an approach to the development of the TEP for a system that should meet safety requirements in the systems development process. It is studied how to incorporate the result of preliminary hazard analysis (PHA) in generating the safety requirements. It is also discussed how to deal with them when the system requirements (i.e., functions, performance, constraints, components, etc) and the safety requirements are integrated into one model. While doing so, we have constructed the required traceability among them, which is necessary and very useful when the safety requirements need to be corrected or be changed. The use of the traceability makes it possible to easily check out whether and how the safety requirements are properly incorporated in the system design process. Furthermore, without the verified traceability, the system cannot be changed or upgraded later. In order to implement the model on a computer-aided tool, we have constructed a database (DB) schema. As a result, the implemented model/DB allows to automatically generate TEP which can be used to measure the performance and safety level of the developed system.
