In order to extend FOO, this research has the object to demonstrate existing the difference of transferred essence and value between the types of factories(Original factory vs Extended factory). A safety product should save consumers from possible harm or risk, but it sometimes gives directly some damage to consumers. For example, like the issue of a germicide problem in 2016, a germicide killed consumers because of harmful chemistry even it should kept their health. This situation refer to 'Safety product betrayal', we expected that safety product betrayal presence/absence conditions moderate the relationship between types of factories, transferred essence and value. We selected a car air-bag as a safety product for study and implemented one study with total 213 participants. As a result, the participants evaluated the value of an air-bag manufactured throughout an original factory higher than the value of an air-bag manufactured throughout an extended factory. Futhermore, they evaluated the transferred brand essence of an original factory's air-bag higher than an extended factory's. However, in the safety product betrayal presence condition, the difference of value and transferred essence between an original factory and an extend factory was disappeared. Indeed, once consumers experienced or saw safety product betrayal, they avoided to buy or use safety products. Therefore, consumers evaluated the value and transferred essence of betrayed safety products is low without the types of manufacturing factories. From the past to now, there was no paper about the relationship between the types of manufacturing factories(Orignal factory vs Extended factory) and safety product betrayal in Korea. Therefore, this research on FOO and safety product betrayal can give new theoretical and operational contribution. In the conclusion, we discussed the contribution of the study results and proposed the limitation and future study.

How to achieve engineering collaboration among diverse engineering activities is one of the key topics in manufacturing fields nowadays. The infrastructure for collaborative engineering is essential, and it can be realized by information technologies and intelligent engineering applications in digital environments. Digital Manufacturing is a technology to facilitate effective product developments and agile productions by computer models representing the physical and logical schema and the behavior of real manufacturing systems including products, processes and factories. A digital factory as a well-designed and integrated digital environment is incorporated in it. In this paper, digital manufacturing is recommended as a good strategy for collaborative engineering, especially in product developments and productions. By business process analysis and some case studies, we suggested sophisticated digital models are very useful to concurrent and collaborative engineering. It is expected that digital manufacturing is a very good strategy for achieving dramatic time and cost savings in many engineering activities of many manufacturing industries, including machinery, automotive and shipbuilding.

There has been a growing interest in automation of factories in the country. And, the development in this regard has been actively attempted. In particular, on the basis of the "innovation 3.0 strategy of manufacturing industry", interest in the smart of the manufacturing plant of small and medium-sized enterprises has increased rapidly. As well as policy for building smart plant, technical, seeking a strategic approach. But, in order to introduce such a smart plant or factory automation systems, manufacturing plant security with vulnerability and personal information protection problems, it should always be top priority there. Accordingly, we provide the applicable lightweight secure protocols in RFID communication. It is a wireless communication technology that is most often introduced for factory automation. Our proposed lightweight secure protocol in this study, less the number of calculations in comparison with the existing public key-based and the symmetric key encryption algorithm. And it is fast in compare with the existing protocol. Furthermore, we design that it system can support to low power consumption and small consume the memory size.

This research was conducted to evaluate the effect of improvement in work environment and of segregation in a fluorescent lamp manufacturing factory. Among the total of 80 workers, 8 workers whose mercury concentration in urine reached a hazardous level ($200-299{\mu}g/l$) were moved to mercury free workplace. The follow-up examination for their mercury concentration in urine was done three times ; on May 3, 1988, September 1, 1988 and April 3, 1989. The results were as follows : 1. Mercury concentration in the air was reduced from 0.140 to 0.107 $mg/m^3$ in 4 months, and to $0.087mg/m^3$ in one year after environmental improvement in workplace. However the level still exceeded the Threshold Limit Value. 2. The geometric mean of urinary mercury concentration among 80 workers was $173.0{\mu}g/l\;(5.1{\sim}458.6{\mu}g/l$). The distribution of workers according to urinary mercury concentration showed that 9 workers (11.2%) were above the mercury poisoning level ($300{\mu}g/l$), 24 workers (30.0%) were $200-299{\mu}g/l$, 35 workers (43.8%) were $50-199{\mu}g/l$, and 12 workers (15.0%) were below 50 ${\mu}g/l$. 3. Among the 24 workers whose urinary mercury concentration was 200-299 $50-199{\mu}g/l$, 8 were able to be followed up. Their mean urinary mercury concentration before segregation was $244.9{\mu}g/l$, but decreased to $151.4{\mu}g/l$ in four months, $128.8{\mu}g/l$ in six months, and $46.8{\mu}g/l$ in one year after segregation.

The purpose of this study is to propose a throughput costing as a performance measurement tool to measure cost indicators, which are one of the indicators for evaluating organizational performance in a smart factory manufacturing environment. An empirical study by questionnaire was conducted, and 60 experts were surveyed to verify the hypothesis. As a result of the study, it was concluded that the information provided based on throughput costing is helpful in cost measurement and in evaluating organizational performance efficiency and effectiveness, and it was confirmed that this method has usefulness to support the planning and control process. It is proposed that the use of throughput costing by constraint theory, which can maximize throughput and optimize inventory levels in the manufacturing process, can find solutions to bottlenecks affecting the efficiency and effectiveness of organizational performance.
