Background: Preservatives are used to prevent product deterioration in modeling clay. Parabens, a representative preservative, have been found to be endocrine disruptors and cause skin irritation and allergic reactions. Isothiazolinone preservatives can be irritating to the skin, respiratory tract, and eyes. Thorough investigation and regulation of clay are necessary because clay is marketed to children, who are more sensitive to the toxic effect of chemicals. Objectives: In this study, the presence of 16 preservatives was analyzed in modeling clay and the results were compared with current standards. Methods: A total of 200 samples were collected from 28 children's clay products sold in South Korea (13 from Korea and 15 imported from overseas). Twelve preservatives, such as parabens, were analyzed using high-performance liquid chromatography (HPLC). Isothiazolinone preservatives (chloromethylisothiazolinone; CMIT, methylisothiazolinone; MIT, octylisothiazolinone; OIT, and benzisothiazolinone; BIT) were analyzed using ultra performance liquid chromatography-tandem mass spectrometery (UPLC-MS/MS). Results: Dehydroacetic acid (DHA) was detected the most in the clays at 51.50% (103 cases) detection; 38 cases (median 190.42 ㎍/g) in Korean products and 65 cases (median 169.62 ㎍/g) in Chinese products. CMIT, which is prohibited in Korea, was detected in 14 (median 16.28 ㎍/g) Chinese products. OIT, which has a chemical structure similar to CMIT was found in 28 (median 68.38 ㎍/g) samples in Korean products. Conclusions: The use of CMIT and MIT in children's products is prohibited in Korea and the European Union (EU). The detection of CMIT in Chinese clay products suggests that management is necessary for imported products. It is necessary to review the safety and regulatory status for OIT because OIT was used as a substitute for CMIT and MIT in Korean products.

With the breathtaking stride beingmade in the field of biotechnology, biocatalyst research using genetically modified microorganism (GMM) is actively being pursued in food industry. However, domestic food and food additive regulation standards and the number of examination management examples currently used in industry is lacking significantly. Up till now, there are only 6 examples of domestic GMM examination and approval cases for food production purposes and furthermore they are limited to the production of functional sweeteners. Domestically, although GMM is developed as a processing aid (contained use), if they are used in the production of food, the safety of GMM, including environmental safety, is evaluated. Also the produced food or food additives using GMM need to be separately examined and approved as a novel food. On the other hand, imported products produced using GMM need to gain approval for the final product only. Thus the expense and the time to obtain regulatory approval is advantageous for imported products versus domestically produced products. This commentary is written to create the opportunity to reform the current domestic food GMM regulation by comparing and discussing domestic and foreign case analyses of safety evaluation of GMM and related regulations.

This research covers the development of new technique for composite injection molding of high stiffness Sabot. An analysis of polymer resin is performed by means of making test specimen mold and doing test with accordance of ASTM test guidelines. Structural analysis and simulation of injection molding process are carried out in order not only to estimate but also to predict the characteristics of molding stresses what both product and structure of mold may have. For structural analysis software, Moldflow and LS-dyna are used and universal test machine is utilized for evaluating performance of sabot. Cases of adopting this material to sabot are not announced yet in domestic academic world. In addition to that, materials for polymer-metal mixed injection molding are imported on the whole due to deficient level of domestic technology. Therefore, this new developed injection molding technique using PEI material can make it available to ensure the technology of making mold, injection and design. Finally, this technique may be applicable to another sabot having different radius of warheads from now on.

Fishery products play an important role in Korean food culture, and awareness of the safety of fishery products is increasing in the seafood market. Against this backdrop, Japan has announced a plan to release radioactive water to the sea from 2023. In the case of Korea, it is adjacent to the area to be discharged, so there are concerns about securing the safety of marine products. Therefore, it is necessary to analyze the change in perception and impact of marine product consumers due to the discharge of contaminated water and to study appropriate countermeasures when discharging contaminated water from nuclear power plants. In this study, the current status of radioactive contaminated water discharge in Japan was summarized, and a survey was conducted on the change in the consumption perception of marine products according to the discharge of contaminated water to analyze the factors affecting the consumption change of domestic consumers. According to the survey, 85.3% of the respondents said that it will affect the purchase of domestic marine products if Japan starts discharging contaminated water from nuclear power plants. Moreover, 85.5% of the respondents said it will affect the purchase of imported marine products.

The number of French movies imported to and released in S. Korea is constantly increasing. All French movies released in Korean theatres, however, are not a great success. For the domestic film market and audiences, the idea French cinema is generally equivalent to 'diversity cinema' or 'arthouse films' is common notion. In this respect, French movies introduced throughout the country would be culture product into which one can read other cultural significances different from that of domestic cinema, and also serve significant cultural value to understand diversity in cinema, for domestic audiences. However, it could be said that French movies, in common with Hollywood films, obey rules in the film industry and needs for audience trends. In this content, what the researchers want to do is to analysis the tendency of the domestic audience reception and main causes of commercial success in the domestic film market, analysing Taken produced in France. The analysis, most of all, suggests the consideration for the film industry beside the notion of cultural diversity in cinema, as imported films are released in the domestic theatre. For this, the study examines the promotional strategy the french cinema perceived generally as the arthouse film applies extensively, analysing on Taken, and inquires into factors of commercial success, using SWOT Analysis. This study, the first of all, (briefly) examines what audiences consider when they choose a film to watch, articulating (generally) the choice-and-consume modality of the domestic audience. And then, it examines dominant factors Taken was a commercial success in domestic film market, even though the film is a french film, using SWOT Analysis. On the basis of SWOT Analysis, finally, this study draws up promotional plan for Taken, and shed new light on dominant preconditions, when the foreign cinema would be imported from the now on.

Country of origin is very important in terms of consumers right to know, protection of producer, national finance and tariff preference etc. The principal issues related to country of origin are breaches of origin mark, determination of origin of OEM products, domestic products using imported raw materials, exports products, and fairness of penalties. This study focus origin mark issues on key components and set products which have not been treated so far. First, Origin mark issues on key components need to introduce multiple countries of origin for the same products. Some specific products, which are considered important key components or materials, has to mark multiple country of origin in terms of portion and significance. Next, Origin mark issues on set products need to expand the objects from 15 listed items of Korea Foreign Trade Act to all items of HS tariff schedules of Korea Customs Act. A set products which below 15% of components can mark single country of origin like FTA agreement such as Korea-EU FTA, Korea-EFTA, Korea-US FTA and Korea-Peru FTA.
