  • Scientists and engineers without borders (SEWB) was established on 2009 as the NGO having specialist groups to support the underprivileged in developing countries living in the isolated area and having water and sanitation problems. After the SDGs were suggested by the UN on 2016, activities are globally conducted by the nation, NGO and etc. to improve health and education of the underprivileged in developing countries. SEWB also have been conducted the projects in Korea and developing countries to reduce the gap of the infrastructure between the developed and developing countries and to help sustainable development in the developing countries by providing appropriate technology. In Korea, SEWB have been held international conference on appropriate technology (ICAT), lectures, and competitions for specialists and students. In developing countries including Cambodia and other 5 countries, SEWB have been provided water packages funded by iCOOP KOREA and volunteer opportunities. Since 2019, 'SEWB sustainable village development project' have been conducted in Bot Veng village, Cambodia to improve infrastructures on water, electricity, transportation, and agriculture by using desalination system, Solar Cow system, strengthened wooden bridge, and poultry farm, respectively. The developed solution for developing countries from SEWB could contribute to eliminate the water shortage and poverty.

  • This paper focused on finding a cost-effective LTE mobile network design methodology, suitable for socio-economic circumstances of developing countries. Developing countries have different requirements and circumstances compared with those of developed countries that had deployed LTE networks in advance, thus a differentiated way of design and deployment methods are necessary. This paper analyzed LTE design-related attributes of developing countries, identified relevant technological requirements and appropriate technologies, and suggested design methodologies. These suggestions were verified through the case studies of several developing countries that a Korean telecommunication company (Korean telecom company A) had participated in the LTE design and deployment for future reference by other developing countries.

  • Present-day world economy is characterized by : technology nationalism, economic regionalism, market protectionism, multinational corporations, efc. All nations are striving for intensifying national economic rivalry and seeking after their own interests above everything else. Many regions of the world are also forming trading blocs, which could negatively affect nonmember states. The ultimate way to meet these difficulties is to establish production facilities in the countries imposing trade regulations. However, as the existing models of direct forrign investment (DFI) do not account for the particular nature of Korean firm's DFI activities, a new point of departure is imperative. It is because of this that Korean firms have only limited firm-specific advantages, the basic precondition of extant DFI theories, compared with their developed counterparts.

  • In order for developing countries to design and deploy Long Term Evolution (LTE) network in a cost-efficient manner, the differentiated way of technological design and deployment methods are necessary as compared to those for advanced countries. This paper focused on Radio Access Network (RAN) design methodology for developing countries that consists of major part of the network cost. To verify the effectiveness of the suggested design methodology, a Korean telecom company A's actual design experience in an African developing country was examined.
