Background: Salmonella enteritidis (SE) was the main cause of the pandemic of foodborne salmonellosis. The surface of eggs' shells can be contaminated with this bacterium; however, washing them with sodium hypochlorite solution not only reduces their flavor but also heavily impacts the environment. An alternative to this is surface sterilization using low-energy electron beam. It is known that irradiation with 1 kGy resulted in a significant 3.9 log reduction (reduction factor of 10,000) in detectable SE on the shell. FAO/IAEA/WHO indicates irradiation of any food commodity up to an overall average dose of 10 kGy presents no toxicological hazard. On the other hand, the Food and Drug Administration has deemed a dose of up to 3 kGy is allowable for eggs. However, the maximum dose permitted to be absorbed by an edible part (i.e., internal dose) is 0.1 Gy in Japan and 0.5 Gy in European Union. Materials and Methods: The electron beam (EB) depth dose distribution in the eggshell was calculated by the Monte Carlo method. The internal dose was also estimated by Monte Carlo simulation and experimentation. Results and Discussion: The EB depth dose distribution for the eggshells indicated that acceleration voltages between 80 and 200 kV were optimal for eggshell sterilization. It was also found that acceleration voltages between 80 and 150 kV were suitable for reducing the internal dose to ≤ 0.10 Gy. Conclusion: The optimum irradiative conditions for sterilizing only eggshells with an EB were between 80 and 150 kV.

Purpose: The purpose of this study was to determine the effect of agricultural exports and imports on economic growth in Bangladesh and propose an upgraded and customized model of the supply chain for agribusiness growth in Bangladesh to achieve plain sailing and systematic operation and financial gains at home and abroad. Research design, data, and methodology: All data in the research have been collected from secondary sources. Gross domestic product was used as the dependent variable and exports and imports of agricultural products were used as independent variables. Pairwise Granger causality was utilized to see the impact of the variable responsible for the economic growth in Bangladesh and the causal relationship between the variables analyzed was measured using Johansen co-integration test. Results: From the empirical analysis, the researchers observed that agricultural commodity imports and exports have a unidirectional impact on economic growth in Bangladesh and a long-run causal link with economic growth in Bangladesh. The suggested supply chain model of agribusiness aids in achieving smooth operations, systematic management, and monetary gains both domestically and internationally. Conclusions: This paper contributes to the development of a more effective and profitable agribusiness supply chain in Bangladesh systematically through their theoretical and practical implications.

From 1990s to the present, in China, residential communities has developed rapidly in terms of government policies and living environments. With economic development, dwelling commercialization and socialization gradually reshaped the housing distribution system and local government management in Chinese urban area. After this process, dwellings were endowed with commodity attributes, which were planned and designed depending on residents' requirements of life. During the 30 years of social transformation, Chinese citizens' lifestyle also had huge changes. In this period, the forms of residential area improved constantly to keep pace with social development. This study aims to research the features of contemporary communities and survey citizens' lifestyle changes to find the reasons of the evolution of communities. Moreover, in this paper, there is a clear explanation of the reasons why gated communities are popular in Chinese urban area. In addition, comprehensive data analysis is derived from a questionnaire administered in Shanghai, China. In this part, the questionnaire surveys what factors about lifestyle influence the transformation of living environments and residential buildings. The results of survey show that residents have housing preferences dependent on their lifestyles, and their daily needs related with environmental features.

In this paper, we codify the objective function that should be optimized by using Genetic Algorithm instead of Heuristic method to solve these problems. So, each bit that constitutes one structure can signify each commodity. Therefore, we can exchange customers without restriction if the traveling distance diminishes among the districts. Furthermore, even though the capacity of a customer's commodities exceeds that of a vehicle, the following vehicle can be allocated. Also, we obtained good result by testing with real data. To be brief, we can effectively allocate innumerable commodities, that have various magnitudes and weight, into restricted capacity of the vehicle by applying genetic algorithm that is useful in solving the problems of optimization.

한·중 양국은 1992년 수교 이래 문화적 공통성과 지리적 인접성 그리고 상호보완적인 경제구조 등을 바탕으로, 정치·경제·사회·문화 등 모든 분야에서 유례를 찾아 볼 수 없는 비약적인 발전을 가져왔다. 특히 중국은 한국의 최대 교역국으로, 그리고 한국은 중국의 제3대 교역국으로 부상하였으며, 2008년에는 전략적 협력 동반자 관계로 격상했다. 현재 국제 통상관계에 있어서 WTO/DDA협상이 난항을 겪고 있는데 반해, FTA는 전 세계적으로 심화와 확대를 거듭하고 있으며, 한·중 양국도 각각 그 어느 나라에 뒤지지 않는 다각적이고 적극적인 FTA 협상을 추진하고 있다. 특히 1997년 금융위기 후 절감한 지역 경제협력의 필요성이 요구됨에 따라 중국은 2005년 아세안과 FTA체결을 시작으로 여러국가에 관심을 표명하였으며, 한국에도 FTA에 추진에 적극적으로 접근하고 있는 상황이다. 지난 5월 28일에는 이명박 대통령과 중국 원자바오 총리와의 회담에서 이에 대한 내용을 언급하였는바, 가까운 시일 내에 본격적인 추진협상이 이루어지리라 예측된다. 이에 중국과 FTA의 본격적인 협상에 대비하여, 한국이 어떤 협상방식을 선택할 것인가에 정책적 제언과 관심이 집중되고 있다. 일부 학자들은 한·중 FTA는 포괄적 협상을 하되, 지속적 논의를 위한 프로토콜을 확정하는 지속형 FTA를 추진해야 한다고 주장하고 있으나 본 연구는 한·중 FTA는 상품무역·서비스·투자분야를 포함하고 협상에서 일괄적으로 타결하는 포괄적 FTA가 되어야한다고 주장한다. 본 연구는 중국의 기 체결된 FTA 협상사례를 통해 중국의 협상방식의 특징을 살펴보고 시사점을 도출하였다. 중국은 현재 아세안, 파키스탄, 칠레 등 개도국과는 단계별 혹은 지속형 FTA 협상방식을 취하고 있으며, 뉴질랜드, 싱가포르 등 선진국과는 일괄타결형 포괄적 FTA 협상방식을 취하고 있다. 중국과의 FTA 협상에 있어서 한국은 농업시장 개방과 국내 이해집단과의 관계 등 쉽지 않은 이슈들이 잔재하고 있으나, 이들은 주로 상품무역 분야에 포진되어 있다. 반면에 중국은 금융·통신 산업이 개방될 경우 중국경제의 전반적인 기반이 위험에 노출하게 되는데, 이들은 주로 서비스무역 분야에 포함되어 있다. 따라서 한국은 협상 범위를 상품무역뿐만 아니라 서비스무역 나아가서 투자 분야까지 넓혀야 이슈간의 교환이 가능해지며, 협상타결의 여지도 충분하리라 판단된다. 즉, 한·중 FTA에 있어서 한국은 뉴질랜드, 싱가포르 사례와 유사한 포괄적이며 협상에서 일괄 타결하는 협상 방식을 채택해야 할 것이다. 이러한 방식으로 인하여 한국은 관세 철폐로 인한 무역 창출효과와 무역 전환효과 나아가 서비스 분야에서 미국, 유럽, 일본 등 선진국에 대비한 중국시장의 선점효과도 기대할 수 있으리라 여겨진다. 또한 한국은 중국과의 FTA 협상의 성공적인 타결을 위하여 중국 국가 차원의 FTA 협상방식에 대한 정책기조를 파악할 필요가 있으며 이를 토대로 한국에 이익을 창출할 수 있는 협상안을 제시해야 할 것이다. 더불어 본격적인 협상이 이루어지기 전인 현 상황에서 중국의 기 체결된 협상 사례에 관한 체계적인 비교분석도 절실히 필요하리라 판단된다.

The study aims to analyze the adaptation strategies and resilience of tobacco farmers to face unfavorable trading system. The research method refers to a qualitative approach with phenomenological models and case studies. The findings revealed tobacco farmers in Jember developed various adaptation strategies and resilience through farmer group organizations, partnerships, self-capacity building and access to financial institutions based on economic, social, cultural, and experience values from various sources and interactions among fellow tobacco farmers. The tobacco trading system, which is left to the market mechanism, results in low bargaining power of farmers, this encourages tobacco farmers to develop various adaptation and survival strategies, namely through collective activities of farmer groups, partnerships and self-development and access to financial institutions. Dealing with the unfavorable tobacco trading system, tobacco farmers do not switch to other commodity farming but adapt and make Jember a center for tobacco production in East Java and Indonesia. From this findings, it suggests to the government as the regulator does not only provide subsidies for tobacco farmers, but also must provide various technical assistance to increase the ability of tobacco farmers. More importantly, regulations must be made benefit tobacco farmers other than corporations so that equality can be enjoyed by tobacco economy players.
