This study aimed at examining the suitability of $Tenax^{(R)}$ for the migration testing of food packaging materials, which is currently approved in the EU as a dry food simulant. The results are used as a basis to examine the feasibility of introducing $Tenax^{(R)}$ to Korean regulation. The OMVs of test specimen into various solvents (diethyl ether, ethanol, pentane, and acetone) after exposure to $100^{\circ}C$ for 1 hr were compared. Diethyl ether showed the highest OMV ($1.33mg/dm^2$) among the solvents tested. When the tests were conducted with different amounts of $Tenax^{(R)}$ of 2, 4, or 8 g per specimen, the OMVs were 0.75, 1.33 and $1.40mg/dm^2$, respectively. The OMV obtained with a closed system after wrapping with aluminum foil showed a significantly higher OMV ($1.61mg/dm^2$) than that without aluminum wrapping ($1.318mg/dm^2w$) and an open system without lid ($1.06mg/dm^2$). The specific migration rates of surrogates spiked in the polyethylene test film and paper samples into $Tenax^{(R)}$ were compared with those into liquid food simulants including 95% ethanol and n-heptane, and actual foods such as starch, skim milk, and sugar. In general, the specific migration levels of surrogates into $Tenax^{(R)}$ were similar compared with n-heptane, however those were significantly higher than into actual foods. These results suggest that $Tenax^{(R)}$ may be used as a food simulant for the long-term preservation of dried foods and paper products. However, more studies need to be conducted to investigate the factors influencing the migration into $Tenax^{(R)}$, such as the types of foods and packaging materials tested, migration conditions, and surrogates properties etc.

Nowadays, the degree of women participation in society is increasing due to modern society's industrialization and urbanization. Already enrollment of kingdergarten is nearly 30 percent higher already since 2005. Moreover, the figure is swing upward this 2014. therefore, including nursery and day care center have to consider to the highest rate. On the other hand, toddlers in our country spend most of their time in the kindergarten center. So people have to take look at possibility of accidents and we are aware about it. As a result, It was announced that the standard of education for the prevention of accident should be implemented in the toddler's facilities. Despite of accompanying education, The percentage of infant's accident is consistently growing every year. in accordance with that, we need to study about architectural planning considering the rage of the activities for child. Externally, infant safety training is being implemented on current regulation. but, the standard of toddler safety is not internally executed in that facilities. In this study, I analyzed the types of toddler's accident on statistics. I visited different web sites about kindergarten and I also made a research through an interview with a preschool teacher.

The EU regulation of overall migration which is the cornerstone of the limitation to ensure that plastic materials and articles intended to contact with foodstuffs are fit for the intended application, was reviewed. In Council Directives, it was established in detail what simulants, contact times and temperatures are to be used in migration tests performed under standardized conditions. In some cases, conventional conditions for substitution test was provided, because of technical reasons. Moreover, a reduction factor ranging from 2$\sim$5 may be applied depending on the foods, because olive oil which is simulant for fatty foods, is severe solvent compared with most fatty food.

The objective of this report is to introduce the European Union's variation rules governing medicinal products that are subject to post-approval changes. The EMEA outlines a variety of changes occurring to approved medicinal products. It also recommends a marketing authorisation holder to follow specific post-approval applications in various situations. For instance, the Commission Regulation(EC) No. 1085/2003 explains variation types and suggests post-authorisation procedures with which an applicant should comply. In all cases of minor and major variations the applicant has to investigate and validate whether or not the intended changes would have impact on the safety, efficacy and quality of a drug product. The applicant should then submit to the EMEA a variation application with adequate documentation in support of the notified changes. This procedure is implemented to ensure that changes to the approved medicinal product do not cause my public health concerns. In fact, the post-authorisation guidance categorizes post-approval changes into type IA/IB variations, type II variations, and extension applications. Such classifications determine administrative procedures to be followed in an efficient manner. Based on the type of a variation, the regulatory agency opts to reduce or extend the evaluation time-frame. The thrust of the EU's post-authorisation guidance is introduced in text with appropriate explanation. All these information will be likely to be helpful in updating a Korean regulatory guidance that could better deal with post-approval changes to generic drugs available in the market.

The amount of export of paprika has been increased rapidly in recent years. Therefore, its cultivation area has greatly increased in Korea according to current consumer's attraction. Moreover, it becomes one of the major exporting products while it recorded 53 million dollars, in 2009 resulting in 40% of the total vegetables export. Most of the products are exported to Japan, but it is necessary to prolong the quality preservation periods to export paprika to nations like U.S.A. or EU. However, to encourage an export to many countries, washing and disinfection became more important to deal with longer transportation and medical inspection. The non-chemical use is very important due to stronger regulation of safety to agricultural production. Accordingly, this study was performed to determine the optimum conditions and develop a prototype washing machine, hot water washing of paprika. The results were as follows : The working performance of the prototype was 938 kg/hr, and which was 1.5 times higher than the conventional air gun type washing machine. The operation cost of prototype was 30 won/kg, and 56% of the cost was reduced when compared with air gun type washing machine.

To look at Korea trade environment, as increasing the quantity of goods transported in North-East Asia and deepening national competitive, information-oriented logistics environment is needed. That means it is automated work process and can provide value-added service. To do this, logistics business can be efficiently handled through "Electronic Means for the Clearance of Ships" and electronically data processing. Also, by increasing the risk of international terrorism, regulation regarding to logistics security has strengthened around the advanced country, such as USA and EU, etc. or international organization, such as IMO, ISO, etc.. Furthermore, because trade and logistics environment is changing and security becomes more important in logistics area, movement or status information of goods within the port or in entry in/out becomes more and more be needed in real time. In case cross-border logistics activities, international cooperation or agreement between countries is very important. However, different opinions much happened on defining the interface. If to follow one format or type using at a specific country or organization, it was occurred to difficulty in respect of interoperability as well as additional costs or time. Therefore, this paper proposes common interface model to exchange information for the efficient global SCM for using by the output of Korea R&D project, "National Logistics Standardization System Development".

Regulation for the testing and operation of autonomous vehicles on public roadways has been recently developed all over the world. For example, the licensing standards and the evaluation technology for autonomous vehicles have been proposed in California, Nevada and EU. But specific safety evaluation scenarios for autonomous vehicles have not been proposed yet. This paper presents safety evaluation scenarios for extraordinary service permission of autonomous vehicles on highways. A total of five scenarios are selected in consideration of safety priority and real traffic situation. These scenarios are developed based on existing ADAS evaluation and simulation of autonomous vehicle algorithm. Also, Safety evaluation factors are developed based on ISO requirements, other papers and the current traffic regulations. These scenarios are investigated via computer simulation.

The United Nations (UN) has tried to make international agreement to restrict artificial greenhouse gas emissions and the UN has concluded the UN Framework Convention Climate Change (UNFCCC) and the Kyoto protocol. Moreover, in 2012, the European Union announced that they will enforce the Directive 2008/101/EC. Therefore, after 2012, aircraft carriers that depart or arrive from EU will follow that regulation. For these reasons, Korea should prepare systematic and effective policy to reduce greenhouse gas emission from aviation activities. The purpose of this study is to find out effective measures to reduce greenhouse gas emission from aviation activities through research by countries all over the world. Here are the 4 measures to reduce greenhouse gas emission from Aviation activities that were found through research UK and Japan's policies. First, Korea should implement aggressive incentive policies. Providing proper incentive can attract voluntary participation of aircraft carriers to reduce greenhouse gas emission. Second, the government should adopt environmental tax on use of fossil fuels. Third, Korea should adopt the greenhouse gas Emissions Trading Scheme (ETS). Lastly, the Korea government should pull in with the international community to establish world-wide environmental policies.
