  • As today's business environment has become more and more competitive, forward as well as backward flows of products among members belonging to a supply chain have been increased. The backward flows of products, which are common in most industries, result from increasing amount of products that are returned, recalled, or need to be repaired. Effective management for the backward flows of products has become an important issue for businesses because of opportunities for simultaneously enhancing profitability and customer satisfaction from returned products. Since third party logistics service providers (3PLs) are playing an important role in reverse logistics operations, they should perform two simultaneous logistics operations for a number of different clients who want to improve their logistics operations for both forward and reverse flows. In this case, distribution networks have been independently designed with respect to either forward or backward flows so far. This paper proposes a mixed integer programming model for the design of network integrating both forward and reverse logistics. Since the network design problem belongs to a class of NP-hard problems, we present an efficient heuristic algorithm based on genetic algorithm (GA), of which the performance is compared to the lower bound by Lagrangian relaxation. Finally, the validity of proposed algorithm is tested using numerical examples.

  • Graduate Students in engineering at The University of Tokushima can take part in an educational program which is offered long-term internship opportunities (at a company or the government). Onishi, one of authors, took part in this educational program. She is studying environmental conservation at the university and is interested in environmental conservation activities led by residents. Striking a balance between environmental conservation and human economic activities is seen as important to society. However, the continuing in environmental conservation activities is difficult. Therefore, collaborative activities attract attention as a way of the continuing in environmental conservation activities. A person called "co-coordinator" is a key to make many people to participate in the sustainable collaboration activities. The main role of co-coordinator is connecting people who are interested in environmental conservation activities. The purpose of joining in environmental conservation activities is different from person to person depending on where they belong to or where they live. Onishi took part in the educational program to learn the techniques of adjusting the differing interests. She did her internship at environmental consulting company in Kamikatsu town, Tokushima prefecture. She participated in several environmental conservation activities and work experience as a coordinator. Through this experience, she learned not only the technique but also the difficulty of the work. This paper reports the results obtained from her experience.

  • This study sought to identify unique semiotic codes of Korean cuisine, including table settings, service styles, service ware selection, cooking techniques, and the logic behind menu composition. This research also aimed to verify that yangnyomjang reflects the code of Korean food culture. One of key findings from this study was that hidden codes of Korean food were found in their daily set-up for bapsang (dining table), which was found to decodify polysemic characteristics with an emphasis on harmony. These semiotic codes were influenced by the yin and yang philosophy and impact dining activities in our daily lives. Korean bapsang, composed of bap (rice), guk (soup) and banchan (side dishes), helps every individual diner share the semiotic codes of Korean cuisine within the context of paradigm and syntagm. Yangnyomjang, a major component of the Korean menu, also represents a unique code of Korean cuisine in its structure, main ingredients, production, and usage. This study also mathematically verified that a synchronic table setting of Korean cuisine provides diners with more opportunities for potential flavor combinations, compared to the Western service setting.

  • CEPA(Comprehensive Economic Partnership Agreement, hereinafter CEPA) between India and Korea may influence some changes on Korean pharmaceutical industry which shows less competitive advantages than Indian industry in many regards. So the purpose of this paper remains on suggesting the way of enhancing international competitiveness for Korean industry on the basis of double diamond model. Through the comprehensive and deep analysis, our findings on recommendable business strategies for Korea are as follows ; in terms of factor conditions, first, cooperative strategy in R&D for developing generics will be required. Second, Introduction of CMO business can be considered. In terms of demand condition, Korean firms should find out the chance for demand creation in Indian market which has future market potential and American market exploration, as soon as possible. With regards to strategy, structure and competition, trying M&A with leading Indian companies and utilizing well organized medical professionals in India will be considered. In the points of related and supportive parts, lastly, Korean government should try to make so called "National Strategic R&D committee" for pharmaceuticals and bring u-healthcare service to Korea in the first place. If Korean pharmaceutical industry implement above-mentioned strategies, CEPA can be turned into business opportunities from the crisis. As a result, Korean firms shall have more powerful global competitiveness eventually.

  • At least 150 indigenous African cattle breeds have been named, but the majority of African cattle populations remain largely uncharacterized. As cattle breeds and populations in Africa adapted to various local environmental conditions, they acquired unique features. We know now that the history of African cattle was particularly complex and while several of its episodes remain debated, there is no doubt that African cattle population evolved dramatically over time. Today, we find a mosaic of genetically diverse population from the purest Bos taurus to the nearly pure Bos indicus. African cattle are now found all across the continent, with the exception of the Sahara and the river Congo basin. They are found on the rift valley highlands as well as below sea level in the Afar depression. These unique livestock genetic resources are in danger to disappear rapidly following uncontrolled crossbreeding and breed replacements with exotic breeds. Breeding improvement programs of African indigenous livestock remain too few while paradoxically the demand of livestock products is continually increasing. Many African indigenous breeds are endangered now, and their unique adaptive traits may be lost forever. This paper reviews the unique known characteristics of indigenous African cattle populations while describing the opportunities, the necessity and urgency to understand and utilize these resources to respond to the needs of the people of the continent and to the benefit of African farmers.

  • The ferroelectric properties of barium titanate strongly depend on its microstructure, in particular, grain size and distribution. During sintering, $BaTiO_3$ usually exhibits abnormal grain growth, which deteriorates considerably the ferroelectric properties. A typical technique to suppress the abnormal grain growth is the addition of dopants. Dopant addition, however, affects the ferroelectric properties and thus limits the application of $BaTiO_3$. Here, we report a simple but novel technique to prevent the abnormal grain growth of $BaTiO_3$ and to overcome the limitation of dopant use. The technique consists of stepwise sintering in a reducing atmosphere and in an oxidizing atmosphere. The materials prepared by the present technique exhibit uniform grain size and high dielectric properties. The technique should provide opportunities of having $BaTiO_3$-based materials with superior ferroelectric properties.

  • The purpose of this article is primarily to give prominence to the importance of International Business English education. Although English is one of the most crucial parts in international business transaction it has not been treated as one of academical sciences. As English is a main language when the international business transaction is done International Business English should be studied by scholars who majored in international business area. It is true that there has been no study at all regarding International Business English(in this article, it does not mean General International Business English) so far. Anyone who does and learn the international business should have some opportunities to have a contact towards international business correspondence and other documents before they do in reality. However, in Korea, most English education has been focused on general English and English certificate tests at universities. At universities' level, it is certainly a scholars' task to study International Business English education in order to provide decent education to the students. For doing so, this article examine, focusing only on reading part, how International Business English should be taught and especially, how reading skills should be activated and integrated with other language skills. This objective will be fulfilled by asking, what reading means in International Business English, as well as what role reading plays in International Business English education.

  • Enacted for enhancing the competitiveness of the Korean capital market and financial industry, Capital Market Consolidation Act (CMCA) was intended to induce considerable changes such as adopting the concept of financial investment products, regulating financial investment functionally, extending financial investors' business areas and intensifying protection for investors. Employing DEA (Data Envelopment Analysis), this study measures and compares the efficiencies of domestic financial companies between the before and after the enactment of the Consolidation Act. We categorize the financial companies into 4 groups (banks, life insurance companies, property and casualty insurance companies and securities companies) depending on their business types, and evaluate how much and in which direction the Consolidation Act affects the efficiency of each group respectively. The study shows that there is no significant difference between the average efficiency of banks and that of property and casualty insurance companies due to the trade-off between opportunities and threats of the Act. To the contrary, it shows that the respective average efficiencies of life insurance companies and securities companies moved in the opposite directions to a considerable extent. Through empirical tests, we demonstrate the effect of the Act on the efficiency of Korean financial companies, and suggest the countermeasures for each financial group against the Act.

  • Compliance with food group and nutrient recommendations, and self-efficacy, stage of change, perceived barriers and benefits for healthy eating were assessed among a convenience sample of college students majoring in health-related disciplines. Dietary and psychosocial data were collected using three-day food records and scales, respectively. Means (SD), frequencies, and percents were calculated on all data, and logistic regressions were used to determine whether any of the psychosocial correlates predicted the stage of change for healthy eating. Noncompliance with food group recommendations ranged from 53% for the meat/meat alternates group to 93% for the vegetables/juice group, whereas noncompliance with nutrient recommendations ranged from 26% for cholesterol to 99% for potassium. A majority of students (57%) self-classified in the preaction and 40% in the action stages of change for eating healthy. The students' self-efficacy to eat healthy was highest in positive/social situations and lowest when experiencing emotional upset. The most important perceived barrier to healthy eating was that friends/roommates do not like to eat healthy foods, and the most important perceived benefit was that eating healthy foods provides the body with adequate nutrients. The difficult/inconvenient self-efficacy subscale predicted the stage of change for healthy eating. These students would benefit from interactive learning opportunities that teach how to purchase and prepare more whole grain foods, fruits, and vegetables, enhance their self-efficacy for making healthy food choices when experiencing negative emotions, and overcome perceived barriers to healthy eating.
