  • One kind of crowdsourcing techniques which allow drivers to collect and provide traffic information using smartphones and applications is being introduced to ITS system as well. The introduction of crowdsourcing techniques requires changes in the existing ITS based on Insourcing which provide traffic information generated by detectors through VMS. ITS Information have had two problems, one is the high cost and the other is an interrupted service. Experts expect crowdsourcing technique which is created SNS, will overcome problems of ITS. But, there are not many examples and research results. Crowdsourcing technique was utilized in Jeju ATMS project to install ITS on the coastal round roads around Jeju since ITS to install point detectors turned out to be non-economic method in case of the coastal round roads with low traffic volume. However, there existed links in which traffic information cannot be generated as there were no smartphone users (crowds) even in the cost-effective crowdsourcing techniques, which indicates the fact that the crowdsourcing method is suitable for urban roads with many smartphone users, but not for local minor roads. On the contrary, insourcing-based ITS is considered to be non-economic method in applying to all roads in the city, but it can be effectively utilized in the local minor roads. Accordingly, Inter-sourcing based ITS operating system in which insourcing is connected with crowdsourcing was suggested in this study.

  • In this paper, we design a new mobile crowdsourcing control scheme based on the incentive mechanism. By using a novel incentive mechanism, mobile nodes can get the maximum payoff when they report their true private information. As mobile nodes participate in the overlapping coalition formation game, they can effectively invest their resource while getting the higher reward. Simulation results clearly indicate that the proposed scheme has a better performance than the other existing schemes under various mobile crowdsourcing environments.

  • This study analyzes the status and results of equity crowdfunding film projects from 2016 to 2018. The film project is conducted in the form of general corporate bonds and participating bonds, and 41.5% of the total bonds were issued, 9.5 billion won. In addition, a t-test analysis of the movie's the breakeven point and audience numbers showed that statistically significant and the average number of audience members was low. Therefore, this study suggests the following for the sustainable growth of the equity crowdfunding film project. Equity crowdfunding brokers should reinforce the review of the possibility of achieving the breakeven point of the film and the factors affecting the box office in the investment manual, and should also actively attract projects on the big films that are likely to be successful. This study is meaningful in that it analyzes the equity crowdfunding film project, which has not yet been widely studied in Korea, and is expected to provide implications in the subsequent research and system improvement process.

  • This research was conducted to monitor ochratoxin A in wine, beer, $makgeolli$ and fermented alcoholic beverages to estimate the exposure to ochratoxin A in the assorted alcoholic beverages. The analytical method for ochratoxin A was based on immuno-affinity column clean up followed by HPLC-FLD. Ochratoxin A was detected in 30 samples of 177 wine (17%), 25 samples of 106 beer (23.6%), 11 samples of 74 $makgeolli$ (14.9%), and 7 samples of 74 fermented alcoholic beverages (9.5%). The average levels of ochratoxin A were 0.039 ng/mL in wine, 0.010 ng/mL in beer, 0.023 ng/mL in $makgeolli$, and 0.014 ng/mL in fermented alcoholic beverages. The daily dietary exposure level of ochratoxin A estimated by using the report on national health and nutrition survey were 0.039 ng/b.w.day from wine, 0.010 ng/b.w.day from beer, 0.023 ng/b.w.day from $makgeolli$, and 0.014 ng/b.w.day from fermented alcoholic beverage.

Analysis of Total Aflatoxin, Ochratoxin A, Zearalenone, Deoxynivalenol and T-2 Toxin Contamination in Nuts (시중유통 견과류의 총아플라톡신, 오크라톡신 A, 제랄레논, 데옥시니발레놀, T-2 독소의 오염도 조사)

  • In the current study, 109 commercial nut samples were collected from different Korean markets and analyzed for the contamination of 5 different mycotoxins (aflatoxin, ochratoxin A, deoxynivalenol, zearalenone, and T-2 toxin) using ELISA kits. The results revealed that the most frequently detected mycotoxin was zearalenone (n=36, 33%), followed by aflatoxin (n=31, 28.4%) and ochratoxin A (n=30, 27.5%). Deoxynivalenol and T-2 toxin were also detected in 22 (20.3%) samples, respectively. Among 109 nut samples, 33 samples (30.3%) were contaminated only with one kind of mycotoxin, whereas 43 samples had at least 2 kinds of mycotoxins. Two samples were contaminated with as many as 4 different mycotoxins, and they were both walnuts. Although the monitoring results revealed the amount of aflatoxin contamination was under the safety criteria, there is no current safety guideline for other kinds of mycotoxins or multiple contaminations in Korea. Therefore, further studies should be performed to reveal the distribution of mycotoxin in different foods and propose appropriate safety guidelines for Korean markets.

  • In this paper, we propose "flexible routing with flex" to provide fast delivery by using the flexible routing for the delivery vehicle and crowd-shipper named flex. To this end, we have introduced an algorithm that can build the delivery plan for delivery vehicles and flexes. The introduced algorithm uses the 2-opt algorithm to construct routes with low complexity and acceptable quality, and the revised saving algorithm to assign customer orders to the flex. The algorithm allows the vehicle and the flex to function complement each other without separating the delivery vehicle from the flex. The experiments consider the 3 different instances named Random, Mixed, Cluster, and show that "the flexible routing with flex" has a better result than "vehicle only". The sensitivity analysis of the flex cost and time penalty shows "the flexible routing with flex" can provide better service not only to the customers who are serviced by flex but also to the customers who are serviced by the delivery vehicle.
