Along with the development of various engineering technologies, the recent manufacturing technology and statistical quality control technology have made much progress. Statistical quality management technology is being researched to maintain and manage the quality of parts per million (PPM) level to satisfy the needs of customers. Among them, control chart is a technique to monitor the variation of various quality parameters. In particular, the defective rate control chart for monitoring fraction of nonconforming has a problem in that too many samples are required when fraction of nonconforming decreases to the PPM level. To solve this problem, there are various methods such as acceptance control chart, but it also has a limitation that it can be used only when the quality parameter is normally distributed. In this paper, we propose a method to manage the minimum defect rate of PPM level in the process where the quality parameter has non-normal distribution characteristics. First, we apply the ZP statistic that can represent the minimum defect rate with a small number of samples. Also, BurrZP distribution is suggested by using Burr distribution that can fit most single-probability distribution. And BurrZP distribution is used to show the performance of BurrZP control chart using 3 sigma control chart method.

The purpose of this study is to create a practical framework that the government can use on negotiating FTAs or setting Corporate Welfare Policies; or to enable FTA researchers, Corporate trade practitioners, FTA consultants, people in charge of various fields to be able to utilize that framework. In this study, the analytic hierarchy process (AHP) was applied to investigate those regulation factors of the Korea-China FTA that may affect the costs of agrifood trade in order to understand how the research results are being ranked. The research findings of this study are as follows. First, we were able to present a methodology of deriving the factor of trade transaction cost from the FTA. Second, we created a frame for factor derivation and designed a research template. Third, we have created a formula that would allow one to put the extracted factors into groups and also help prioritize trade transaction costs in the matter of importance. Finally, we have created a roadmap that would allow the government and executives of various positions write their own FTA regulations.

This paper is to get the cycle time of the vendor with minimum cost in an integrated production and inventory model of single-vendor multi-buyer multi-product supply chain. The vendor is the manufacturer of the product and the buyers are retailers. A manufacturer produces different kinds of products and supplies them to the retailers. The cycle time of the vendor is the elapsed time of two consecutive production start times. All product types have the same cycle time of the vendor. A mathematical model is represented with the cycle time of the vendor and the number of item supply from manufacturer to the retailers during the cycle time of the vendor in a supply chain. The cycle time of the vendor that minimizes the cost in a supply chain is obtained with the cost factors of the manufacturer. The number of item supply from the manufacturer to the retailer is obtained with the ordering cost and inventory holding cost of retailer and inventory holding cost of the manufacturer. A minimum cost solution method is suggested. A solution result is compared with the optimal solution and that of the genetic algorithm through a numerical example.

In this paper, we design a return mail forecasting system that can reduce the bounce rate of postal customers for moving. Customers will request a change of address from their service provider if their residence address changes due to a move. At this time, the customer and other customers who have the same address as the previous address or the customer who has the same address after the change of residence are set as the estimated moving customers. A mail return prediction system is designed to reduce the mail return rate of the estimated moving customers by performing residential address renewal for these customers. This system can prevent waste of manpower and material resources in management and loss of returned mail, and it is possible to update the residence address by using short text message and can prevent exposure of personal information due to membership.

Domestic Coal-Fired Power Plant Industry according to industrial accidents by industry from 2008 to 2017, the number of workers killed every year is about 6 and the number of injured workers is about 95. The increase in industrial accidents in the coal-fired power plant industry is not leading to an appropriate statistical analysis of industrial accidents occurring in the coal-fired power plant industry. Accordingly, in this study, industrial accidents of five domestic power generation coal-fired power plants were analyzed in various ways from 2008 to 2017, and high-risk accident types and work improvement plans were identified. Based on this, high-risk accident types were identified and suggested improvement measures. For the basic data of the preceding research, the public report from the special investigation committee during the coal-fired power plant in 2019 and the data surveyed from the safety diagnosis joint service of the five coal-fired power plants in 2019 were cited. The statistical analysis results from this study quantified the actual injuries, deaths, injuries and mortality rates of 10 years for each power plant headquarters and partner companies of the 5th coal-fired power plant. Using the statistical analysis method, the severity of industrial accidents was identified by identifying the increase and decrease according to the period, the comparison with the same industry, the correlation of social phenomena, the correlations between the injured and the deaths of the five development companies. As a result of the improvement measures for high risk type of disaster, 4M (man, machine, media, management) method was used to analyze the causes of the disaster, and as a result of the analysis, it was found that the equipment factor and the work factor occupy a large proportion of the causes of the fall. Therefore, improvement measures for falling accident prevention were presented as common matters, and improvement measures that could cover the causes of fall in terms of equipment and work were presented. It is expected to be used as an improvement in statistical analysis of industrial accidents and safety education data for power generation industry.

To improve the cognitive performance of preschool, children's electroencephalogram(EEG), concentration level and heart rate variability(HRV) are measured while changing the temperature to 18[°C], 21[°C], 24[°C], 27[°C] and 31[°C] in the test room set as relative humidity 50[RH%], air speed 0.02[m/sec] and illumination 1000[lux]. Measurement condition is uniformly set as 1met of activity while seated and relaxing with the cloth amount of 1.05[clo]. As a result, it was found that sα increased by 40% when the subject was in 24[°C] compared to 31[°C]. Concentration increased by 10[%] under 24[°C] compared to 31[°C]. The standard deviation of normal to normal intervals(SDNN) decreased 12[%] under 24[°C] compared to 31[°C]. Also, aggression decreased by 12[%] under 24[°C] compared to 31[°C]. Therefore, it can be concluded that comfortability and cognitive ability improves under mild temperature such as 21∼24 [°C] better than warm temperature of over 27[°C].

This paper suggests a patient safety management system model for inpatients in hospitals to ensure the safety of patients who may be involved in medication, transfusion and acting. This system was implemented with a OCS / EMR Server, WEB Server, client PC, tablet PC, and bar code scanner to provide acting error prevention and convenience of nursing services. The proposed model shows that the new method by bar code based-recognition system can more efficiently perform to reduce processing time for nursing service, compared with the current approach by verbal recognition system. To compare the effects of the system, the average processing time (elapsed time) from the check of nursing work list to the start of acting and the average error rate of the acting result were measured based on blood transfusion. It is noted in case of the method by bar code-based recognition system that the effects of proposed model are as follows; (a) While the processing time per patient by the current method was 45 minutes, the processing time by the new method was 40 minutes. (b) While the processing error ratio by the current method was 0.5%, the error ratio by the new method was 0.2%.

This study is designed to analyze the management factors of domestic FM(Facility Management) companies on the management performance of user companies and the satisfaction of user companies. Based on prior research, the research model and hypothesis were established. Technology, function, and behavior were selected as management factors of independent FM companies, and management performance and satisfaction were composed of dependent variables. The survey was conducted on 150 building managers who were owners and commissioned to manage the building by building owners and building ground survey and an e-mail survey. For verification, an empirical analysis was conducted using structural equation model analysis. The study found that all of the management factors of the facility management company had a significant impact, and as a result, the study proved that the facility management company's still weak facility management safety atmosphere can be improved and managed to increase the user's satisfaction with the user's company's economic and efficiency maximized, thus leading to customer satisfaction.
