  • The main task of agro-industrial production is to provide the population with food products for the production of which energy is expended in the form of electricity, technical means, fuels and lubricants, mineral fertilizers, etc. Accordingly, we have developed a concept and general methodological principles for the analysis of ecological and biotechnical systems in animal husbandry, it makes it possible to simulate the influence of various factors on the energy and ecological efficiency of systems, to compare and search for energy-saving modes and technologies. General methodological principles have been developed for the analysis of energy efficiency and environmental safety of agricultural ecological and biotechnical systems, which are based on the definition of the bioenergy efficiency coefficient, the quantitative expression of which is the ratio of energy accumulated in products to the total energy consumption for its production. This makes it possible to model with sufficient accuracy the influence of various factors on the energy and environmental efficiency of the system, to compare and search for energy-saving modes and technologies in order to find and select the most energy efficient ones to increase the energy efficiency of the complex.

  • Product Life cycle Management (PLM) is an indispensable tool for manufactures to develop competitive products in an efficient way. This enlarges the number of participants for product development who should understand PLM for their supporting activities. However, burdens for developing example products, maintaining complex PLM systems and training prerequisite skills for engineering tools such as CAD systems prohibit an efficient introductory course to PLM. This paper proposes a comprehensive introductory course to PLM that bases on general product development process. In addition, it enables participants to build their example products with familiar Lego blocks and to construct 3D CAD assembly models by using predefined 3D elements. The PLM system for the course provides an intuitive and simple user environment for participants to specify their parts lists, associated 3D CAD models, and product structure of example products. Experiences on a class of the course show it is a valid and efficient education and training method for the PLM introduction.

  • The mammalian immune system comprises a complex array of cells and molecules that interact to provide protection from pathogenic microorganisms. The beneficial role played by lactic acid bacteria and milk-derived peptides in humans, including their effect on the immune system, has been extensively reported. Lactic acid bacteria and milk-derived peptides, which are present in dairy products, are frequently used as nutraceuticals to improve some biological functions in the host. Activation of the systemic and secretory immune response by lactic acid bacteria and milk-derived peptides requires many complex interactions among the various constituents of the intestinal ecosystem. Thus, the aim of this review was to examine in detail the immunological potential of lactic acid bacteria and milk-derived peptides.

  • The aim of the study was to evaluate the water treatment of pressurized water reactor secondary side by the mixed amine of ammonia and ethanolamine, from the standpoint of corrosion control, as compared with all volatile treatment of ammonia. The pressurized water reactor systems have switched a secondary side pH control agent to minimize the corrosion in the moisture separator/reheater and feedwater heater systems and the transport of corrosion products into steam generator. As results of field test, pH was increased in the steam generator and the wet steam area of moisture separator/reheater and the concentration of Fe were decreased by more than 50% as compared with water treatment of ammonia.

  • Supply chain management is defined as "an integrative philosophy to manage the total flow of a distribution channel from the supplier to the ultimate user". There are many differences between traditional systems and supply chain management systems, There are so many advantages applying SCM concept in inventory management field from the viewpoint of information sharing. While each firm try to optimize the inventory individually in traditional systems, SCM focus on optimizing the channel-wide-inventory making effort to reduce the inventory interrelatedly, The more complex your network of suppliers, manufacturers, and distributors, the more you are likely to gain operational efficiencies by attending on inventory management. The inventory stockpiles at the various sites, including both incoming materials and finished products, have complex interrelationships. Efficient and effective management of inventory throughout the supply chain significantly improves the ultimate service provided to the customer. The purpose of this thesis is to develop the integrated inventory management system for the control of channel-wide inventory on the intranet by applying SCM concept.

  • This study investigated the effect of the level of ethics in food manufacturing of agricultural products processing companies on food safety and product trust. In general, a company's food manufacturing ethics is complex, includes social responsibility, and has a potential impact on stakeholders. The main implications summarized based on the analysis results are the expansion of the HACCP application of the agricultural product processing system, the production of safe agri-food that fulfills social responsibilities with an ethical awareness, including entrepreneurial awareness, from raw materials to processing, packaging, and distribution from a long-term perspective. It was found that it was necessary to secure product trust and to provide education, consulting and management on ethical awareness.

  • This study was focused on the system of regional resource circulation(RRC) of Asan-Si as a case region. So 301 farmers(members of producer organization) who are managing environmental-friendly agriculture (EFA) are surveyed. The RRC system is focused on establishing the system of regional complex farming connected with the seedling fanning and the livestock. The main results surveyed are as follows : First, total cultivated acreage is 574ha. Second, the total quantity of by-products of rices, beans, wheats is 983M/T. Third, the total quantity of nutrient requirement for seeding fanning is 85,335.6kg This research shows how to develop the RRC system for EFA. The development model and strategies are as follows : The first model for the system of regional resource circulation can be called the scenario of the best output for the system of environmentally friendly resource circulation. It is considered to estimate the appropriate number of heads of Korean cattle and hen which can be bred simultaneously. And the second model can be called the scenario of the regional allotment for the appropriate number of heads of those. It is considered to estimate the appropriate number of heads of those which can be alloted by the individual farm or area.

  • Purpose - This paper aims to review cold chain management, especially in the pharmaceutical industry, to explore the cold chain process of delivering temperature-sensitive pharmaceutical products, and to identify areas for further development. Research design, data, and methodology - The paper, based on literature review and corporate analysis, reviews the development and status of the cold supply chain system, including its important role in the pharmaceutical industry. Results - Logistics in this field requires more stages than are typically needed. Due to the unique characteristics of the market, few companies can provide the services; currently, only few global companies with large networks and high technologies can afford to do so. Expanding pharmaceutical markets to meet global demand will require cold chain development, especially in "pharmerging" markets. Conclusions - Cold chain is a highly sensitive market in terms of products being carried within the chain that itself is a complex system. However, at the same time, it is a niche market with new opportunities. Hence, a sound cold chain infrastructure is needed to satisfy companies, governments, and customers for both commercial and public reasons.
