In 2017, the EU-Japan FTA talks were resumed ahead of the G20 summit in Brussels, Belgium, and agreed to abolish tariffs on 95% of all trade items. These figures are highly liberalized agreements that are equivalent to the Pacific Rim Economic Partnership Agreement (TPP). Particularly, Japanese automobiles were aggressively negotiating the abolition of tariffs with 7-year grace period and the gradual elimination of European cheese in 15 years. If the agreement is concluded, the tariffs of 1 billion euros (about 1.3 trillion won) will disappear, and Korea, which has similar industrial structure with Japan, will be hit by the processed food, chemical products, medical equipment, dairy products and automobile industries. do. The purpose of this study is to examine the mutual recognition agreement (MRA) that can directly affect the Korean companies in the content of the Japan-EU FTA and to suggest the implications for the Korean export companies.

The scheduling of planned maintenance problem of a system consisting of a number of components was studied. The purpose of maintenance scheduling is to minimize the cost of maintaining long-term operations. On the system side, the cost of a system shutdown can be minimized by grouping and inspecting a number of components. In addition, proper inspection cycles can be selected for each component to identify the failure sufficiently early to minimize the cost of the failure. To reduce the complexity of the calculations, the 'base interval approach' used in previous studies was applied and, in addition, the inspection cost savings from simultaneous inspections of multiple components were considered. To compare the effectiveness of inspection cost savings, this paper presents the results of simulation analysis performed by referring to the cases in the existing studies.

Due to the high importance of foreign trade in the national economy, Korea has a lot of ports designated as trade ports compared to the small land size. However, because of the poor utilization results, some small trade ports have been criticized for wasteful financing due to redundant investment in SOC. This is because the characteristics and comparative advantage of foreign trade in trade ports have not been analyzed in detail by region. Therefore, this study analyzes the patterns and types of change in the size of trade, number of cargo items handled, and the number of trade target countries in the past 20 years for 19 domestic small trade ports using the time-series cluster analysis technique. As a result of analysis, Korean small trade ports were classified into five growth pattern types according to the analysis index, and characteristics and implications for each type could be derived. Today, as the foreign trade environment changes drastically and the importance of balanced regional development is emphasized, it is very important to study the growth types and implications of small trade ports and the results of this study are expected to provide meaningful implications for regional port development and operation in the future.

In order to present a realistic alternative to agricultural product brands which achieve quantitative growth but minimal qualitative growth, this study attempted to identify the structural factors that affect the agricultural product brand equity and quantitatively analyze the effects of the structural factors on the brand equity. For the quantitative analysis, a survey was conducted among customers with a structured questionnaire. The major results of the analysis are as follows. First, the structural factors of the agriculture product brand equity were theoretically reviewed through many preceding studies in regard to the brand and brand equity. Awareness, quality and loyalty were selected as the structural factors of the agriculture brand equity. Second, when the sub-structural factors of the agriculture product brand equity were analyzed, it was found that awareness includes familiarity, first reminding level, general awareness, sub-awareness, frequency of reference and level of people's logo recollection. Quality includes quality consistence, quality reliability, quality stability, general quality and quality for price. Loyalty includes recommendation, purchase intention, cost premium and repurchase intention. Third, in the analysis of the factors of awareness, quality and loyalty were found to be statistically significant at the 1% level of significance, and it turned out that the higher the awareness, quality and loyalty, the higher the brand equity. Fourth, the factors most influencing the brand equity differed from those obtained using the standardized coefficients. The highest standardized coefficients of the factors on rice and condiment vegetables were those for quality with values of 0.486 and 0.581, respectively, and the highest standardized coefficients of the factors on fruits and fruit vegetables were those for loyalty with values of 0.536 and 0.490, respectively. Finally, it was found to be more effective to develop brand policies using an approach based on awareness, quality and loyalty by item. Also, focusing on enhancing the quality when developing brand policies for rice and vegetables, or focusing on enhancing loyalty when developing brand policies for fruit and vegetables was found to be more efficient using the limited resources.

This study was investigated to review the potentials of irritation and skin sensitization of active ingredients and end-use products of pesticides for pesticide registration, prediction of irritation and sensitization, and data requirements for other purposes. Pesticide irritation and sensitization referred to the Pesticide Manual(14th edition), while toxicity was evaluated based on the data submitted by the pesticide registrant. Totally 148 active ingredients and 149 end-use products were analyzed to compare the positive response, formulation type, and correlation between active ingredients and products. Among active ingredients, ratio of positive response to skin irritation, eye irritation, and skin sensitization were 18.8, 47.0 and 20.6% respectively. While, positive response to skin irritation, eye irritation, and skin sensitization of the products were 14.9, 38.9 and 23.6%, respectively. Emulsifiable concentrate showed the highest positive response among formulation types showing skin irritation 31.3%, eye irritation 81.3%, and skin sensitization 31.3%. On the other hand granule type showed the lowest response with skin 4.8, eye 14.3 and sensitization 14.8%. There was no correlation by active ingredient content on irritation and sensitization of products. However, both active ingredients and products showed same positive response were skin 73.1%, skin sensitization 66.2%, and eye irritation 44.7%. By the these results, correlation between technical grade of active ingredients and end-use products would be use for pesticide management at the screening stage, especially skin irritation and skin sensitization.

The Korean economy has achieved continuous economic growth for the past several decades thanks to the government's export strategy policy. This increase in exports is playing a leading role in driving Korea's economic growth by improving economic efficiency, creating jobs, and promoting technology development. Traditionally, the main factors affecting Korea's exports can be found from two perspectives: economic factors and industrial structural factors. First, economic factors are related to exchange rates and global economic fluctuations. The impact of the exchange rate on Korea's exports depends on the exchange rate level and exchange rate volatility. Global economic fluctuations affect global import demand, which is an absolute factor influencing Korea's exports. Second, industrial structural factors are unique characteristics that occur depending on industries or products, such as slow international division of labor, increased domestic substitution of certain imported goods by China, and changes in overseas production patterns of major export industries. Looking at the most recent studies related to global exchanges, several literatures show the importance of cultural aspects as well as economic and industrial structural factors. Therefore, this study attempted to develop a forecasting model by considering cultural factors along with economic and industrial structural factors in calculating the import volume of each country from Korea. In particular, this study approaches the influence of cultural factors on imports of Korean products from the perspective of PUSH-PULL framework. The PUSH dimension is a perspective that Korea develops and actively promotes its own brand and can be defined as the degree of interest in each country for Korean brands represented by K-POP, K-FOOD, and K-CULTURE. In addition, the PULL dimension is a perspective centered on the cultural and psychological characteristics of the people of each country. This can be defined as how much they are inclined to accept Korean Flow as each country's cultural code represented by the country's governance system, masculinity, risk avoidance, and short-term/long-term orientation. The unique feature of this study is that the proposed final prediction model can be selected based on Design Principles. The design principles we presented are as follows. 1) A model was developed to reflect interest in Korea and cultural characteristics through newly added data sources. 2) It was designed in a practical and convenient way so that the forecast value can be immediately recalled by inputting changes in economic factors, item code and country code. 3) In order to derive theoretically meaningful results, an algorithm was selected that can interpret the relationship between the input and the target variable. This study can suggest meaningful implications from the technical, economic and policy aspects, and is expected to make a meaningful contribution to the export support strategies of small and medium-sized enterprises by using the import forecasting model.

This study investigates the effect of organic certification of apples on consumer preference in China as a way to support the expanded export of Korean apples to China. A choice experiment was designed to analyze the apple consumption in China. A total of 298 Chinese consumers answered the survey, and multinomial logit models were used to analyze the results. Organic certification was identified as an important determinant of consumer preference for apples in China, affecting both the evaluation and choice of country of origin. The results also indicated that Korean organic certification significantly increased the probability of Chinese consumers choosing Korean apples. Thus, organic certification by the Korean government should be strengthened to promote apple exports to China, plus the results of this study may provide useful information to promote agricultural product exports and improve the organic certification system.

The present study was carried out to assess exposure & risk for Korean by total and inorganic As intake through agricultural products. Total arsenic analysis was performed using microwave device and ICP-MS. 50% MeOH extraction and anion-exchange HPLC-ICP-MS method has been used to determine arsenic species. 329 samples covering 20 kinds of agricultural products were collected from various retail outlets and markets across Korea. The concentration of total As was in the range of 0.001~0.718 mg/kg, while inorganic and organic arsenic species in all samples was not determined. For risk assessment, probable daily intake was calculated and compared with provisional tolerable weekly intake (PTWI, 15 ${\mu}g$/kg b.w./week for inorganic arsenic) established by JECFA. The median daily exposure to total and inorganic As by intake of agricultural products except rice was ranged 0.0002~0.012, 0.0001~0.001 ${\mu}g$/kg b.w./day, corresponding to 0.01~0.5%, 0.002~0.1% of PTWI, respectively. The median level of total and inorganic As intake through rice was 0.603 and 0.041 ${\mu}g$/kg b.w./day, and 28.1% and 1.9% of PTWI, respectively. Therefore, the level of overall exposure to arsenic for Korean through agricultural products was below the recommended JECFA levels, indicating of least possibility of risk.
