Development of an accident estimation model based on accident data can be made after accident occurrences. However, the taking of historical accident data is not easy, and there have been differences between real accident data and police-reported accident data. Also, another difficult shortcoming is that historical traffic accident data better consider driver behavior or intersection characteristics. A new method needs to be developed that can predict accident occurrences for traffic safety improvement in black spots. Traffic conflict decision techniques can acquire and analyze data in time and space, requiring less data collection through investigation. However, there are shortcomings: as existing traffic conflict techniques do not operate automatically, the analyst's opinion could easily affect the study results. Also, existing methods do not consider the severity of traffic conflicts. In this study, the authors presented traffic conflict decision criteria which consider conflict severity, including opposing left turn traffic conflict and cross traffic conflict decision criteria. In order to test these criteria, the authors acquired three signalized intersection images (two intersections in Sungnam city and one intersection in Paju) and analyzed the acquired images using image processing techniques based on individual vehicle tracking technology. Within the analyzed images, level 1 conflicts occurred 343 times over three intersections. Some of these traffic conflicts resulted in level 3 conflict situations. Level 3 traffic conflicts occurred 25 times. From the study results, the authors found that traffic conflict decision techniques can be an alternative to evaluate traffic safety in black spots.

This study investigates the safety of Hanwoo beef and consumer satisfaction through the questionnaire for 280 consumers of Hanwoo beef in Gyeongsangbuk-do. Among 280 copies, only 245 copies were adopted to analyze. The subjects consisted of 82(33.2%) males and 163(66.5%) females and their age 55(22.4%) of twenties, 52(21.2) of thirties, 86(35.1%) of forties and 52(21.2%) of over fifties. The frequency of purchasing Hanwoo beef was that as consumers were getting older, they tended to purchase more beef. The most popular place for purchasing Hanwoo beef was Hanwoo specialty stores(55.1%), but there was no statistical difference. The most favorite retail cuts for Hanwoo beef was Loin(44.5%), followed by ribs(26.1%). The consumers thought that selling imported beef turned into Hanwoo beef occurred 70.2%(sometimes), and 20.8%(yes), 6.1%(don't know) and 2.9%(never). For a method to prevent it, the traceability system(60.4%) was the highest, followed by country of origin labelling(16.3%). Taking the perfect score 5 points about the country of origin marks and traceability, trustworthiness which was presented the highest points was 3.31, recognition 3.29, experience 3.26 and practical effect 3.07. The average of two systems was 3.23. The average points of the safety and consumer trustworthiness of Hanwoo beef were 2.96 points and 3.13 respectively. The safety and the consumer trustworthiness showed statistically significant difference according to educational background, income, and jobs. From the results obtained in the current study, it is concluded that if the traceability system and country of origin labelling are managed well by the government, safety and consumer trustworthiness will be improved.

Using the materials collected from nine farms in a three-way cross system to produce commercial pigs produced from F1 sows (Landrace $\times$ Large White) $\times$ Duroc, the power of individual discrimination and parentage of the 13 microsatellite (MS) marker set that has been suggested for individual/brand identification (traceability) was empirically tested. Initially, genotypes of the parental population ($F_1$ sows and Duroc), and commercial pigs were determined and the genotype frequency and polymorphic index were estimated using the Cervus 2.0 program. The probability of identity among genotypes of random individuals, that random half sibs and that of full sib individuals, based on the genotypes from 91 $F_1$ sows and Duroc were expected to be $4.94{\times}10^{-34}$, $8.16{\times}10^{-23}$ and $2.01{\times}10^{-08}$, respectively, using the API-CALC version 1.0 program. When commercial pigs were included, the estimates increased to $3.74{\times}10^{-35}$, $5.48{\times}10^{-25}$ and $2.96{\times}10^{-11}$, respectively. For the empirical verification of the estimated powers of individual discrimination and parentage, the parentage test was performed for 452 commercial pigs using PAPA version 2.0, and individuals with the same genotype were investigated using the Cervus version 2.0 program. Parents for all commercial pigs were successfully estimated and no identical individual was identified in the pedigree. Although the individual discriminating power was not fully verified because of the lack of individuals corresponding with the theoretical power, the 100% efficiency of parentage test was clearly confirmed. Therefore, we believe that the 13 MS marker set in conjunction with management record/information for the pig production kept in a farm/brand should be useful in the pork traceability in a brand unit.

The Game development process that the Korea Game Development Infinity researches and publishes has laid important groundwork for the game industry. However, the game design cannot guarantee a software quality because an artifact is made incorrect by a game planner's new idea and modification. In this paper theorized the system to maintain artifacts consistently that is generated in planning phase and make changed contents traceable. First, it defined an ACT graph to represent relation of between artifacts, a ACT table that traces and manages it changes and a table of artifacts change history. Also, it suggested the ACT process applying as we mentioned above. Then we worked a case study to verify the change tracking technique which is presented. In a case study, we find game designer is capable to grip and modify a change of artifacts when it occurs a change of game design artifacts. As a result of that, we can save the time and effort to maintain the consistency among game design artifacts.

A nonlinear FEM analysis of steel members under very-low-cycle loading has been performed in conjunction with experimental works. This analysis is an FEM tracing toward cracking of steel members under cyclic loads such as a strong earthquake. After verifying the procedure by comparing global hysteretic behaviors from the analytical and experimental results, the local stress-strain hysteresis at critical sections for large cyclic deformations was traced by the numerical analysis. Local strain history was discussed in relation to cracking. Based on the experimental and analytical results, a new approach to seismic safety assessment for steel members was proposed in this paper.

The main goal of this study is to survey the actual condition of farm household adopt traceability of agricultural products and the consumers' recognition of the traceability. Thirty six farm household adopted traceability of agricultural products and one hundred twenty three consumers were surveyed for this study. A total of the cultivated area of surveyed farm household was 39.6ha－owned land(21.2ha) and Rented land(18.4ha)－and the cultivated area of crops with the traceability of agricultural product was 15.7ha, consisting of 39.6% of the whole cultivated area. 22.2% of agricultural traceability products was cultivated bychemical method and 77.8% of the them by environment－friendly agricultural methods－organic cultivation accounts for 2.8%, no－chemicals cultivation 47.2% and low－chemicals cultivation 27.8%. As a result of the consumer survey, 75.6% of respondents recognized agricultural product traceability and only 29.0% of them had experience to purchase traceability products. But 61.0% of surveyed people had intention to purchase traceability products in the future. It was found that consumers wanted to know about production traceability information of farm products in order to identify quality certification including environment－friendly certification, product quality such as taste, weight, grade, and the use of insecticides and fertilizers regarding use frequency and kinds of chemicals.

The demand for food safety has emerged as a major social issue due to changes in diet patterns and consumers' perceptions, along with the advancements in society and the development of the food industry. Consumers are demanding more information about the food they consume, and are sensitive to food scandals. With such interest in food safety, blockchain technology is attracting attention as a means of effectively responding to poor food management resulting in food fraud or unsafe distribution. By ensuring the accuracy of, and trust in, traceability in the food supply chain, it is possible to build trust between traders and to ensure safe food distribution. This paper proposes a next-generation agri-food distribution system that can provide and manage (for suppliers, consumers, and distribution officials) a variety of agri-food information, such as the history, distribution, safety, quality, and freshness of food. Information on product status and distribution status in all processes, including production, processing, distribution, sales, and consumption, can be monitored and controlled in real time (anytime, anywhere), and users can check the safety level of each type of food in real time through an app.

Agricultural products are one of the major food, But in recent years, It's not easy for Consumers to buy them. Cause there are not sure about the quality of the cheap foreign agricultural product imported. There are not even sure where they have been produced, Some excessive use of domestic pesticides, And Environmental pollution caused by soil contamination of plantation, It's not only matter with the conscience of the Sellers and producers. The government recommends agricultural producers to attach the mark to identify where the products are made originally. However, if producers do not comply with the recommendation, it become useless. Recently, because of the increased interest to health and food, Consumers want accurate and reliable information about The agricultural products, They buy. In this paper, Based on the RFID technology, RFID tags attached to agricultural products when consumers buy, Through the RFID reader to read RFID tags, Which make Easy to accurately convey Production of agricultural information and safety information to consumers. These features have been implemented with the traceability system.
