  • Gyeongju in Saro or Silla one of ancient kingdoms in Yeongnam region of southeast Korea, had been developed as a capital city for thousand years despite its unfavorable geographical location being leaned to the southeastern part of the Korean Peninsula. Although this rare case in the world resulted from various facts relevant to political capability and intelligence of the ancient Gyeongju people, the geomorphic characteristics played a key role for its political development. In this paper, we discuss the establishment and growth of ancient kingdoms in Gyeongju area in terms of geomorphological factors such as the Taebaek and Sobaek mountain ranges, distribution of fault lines and alluvial fans along the eastern coast of the peninsula, characteristics of the coastal regions. That is, abundant grain supply from alluvial fans in Gyeongju and surrounding areas, high population-carrying capacity of land and positioning of an ancient supercity were made possible by the geomorphological contributions. Furthermore, Gyeongju could hold the lead in competition with surrounding kingdoms by accumulation of wealth and military superiority derived from production and circulation of salt and iron works. Gyeongju had become the capital of ancient kingdoms due to the geomorphic advantages during the ancient times in Korea.

  • Industrial complexes have have been played an important role in various aspects such as national industrial development, economic growth. However, it is a cluster of manufacturing facilities which has a great impact on the surrounding area and the overall domestic environment during the operation of the facility. In this study, environmental influences and siting characteristics of industrial complexes were investigated based on the environmental impact assessment report from 2009 to 2019. The development tendency of industrial complexes is continuous decline, and major development areas are Gyeonggi, Gyeongsang and Chungcheong areas. We also confirmed that the average area of defenestration due to industrial complex is on the decline. Furthermore, the residential area and educational facilities, and the exposed population affected by industrial complex is constantly increased.

  • Pyeongtaek·Dangjin port handles the largest volume of finished vehicles in Korea, including more than 95% of imported cars. However, since the volume of imported cars has been stagnant since 2015, officials planning to invest in port development or automobile-related industries must make new forecasts. Economic variables such as the GDP often have been used in predicting automobile volume, but prior research showed that the impact of these economic variables on automobile volume I has been gradually decreasing in developed countries. These variables remain important predictors, however, in developing countries that experience rapid economic growth. In this study, predicting the volume of imported passenger cars at Pyeongtaek·Dangjin port, the decreasing Korean population was a major factor we considered. Our forecast showed that the volume of imported passenger cars at Pyeongtaek·Dangjin port will gradually decrease -by 2021. The Mean Absolute Percentage Error (MAPE) verification was performed to measure the accuracy of the predicted results, and the scenario analysis was performed on the share of imported passenger cars.

  • As the COVID pandemic has been prolonged, 'Contact-free' has emerged as a major trend keyword. Naturally, most people don't go out and eat at home. As a result, sales of products that can easily cooked such as 'meal-kits' have increased remarkably. Although the number of vegetarians is increasing rapidly in Korea, the domestic market has not been activated. Most vegetarians are cooking or eating HMR together due to the lack of vegetarian restaurants and vegetarian menus. According to the survey, the subjects perceive meal-kit as positive as their experience with meal-kit expanded, and this positive perception and the need for vegetarian meal-kits had a positive effect on the purchase intention of the vegetarian meal-kit. This study presents the direction and potential for development of vegetarian meal kits that meet consumer needs. It will be used as a basis for the development of products and expansion of the market for vegetarian meal-kits.

  • A decrease in fertility rates causes problems such as decrease in the working-age population, and has a significant impact on national policies. Currently, the Republic of Korea has a conscription system that imposes military service on all men over the age of 18. However, the transition to the volunteer miliatry system is emerging as a social issue due to the decrease in the fertility rate. In this paper, news articles and comments searched for through the keyword ' volunteer miliatry system' were collected to analyze the social perception of the volunteer miliatry system from 2018, when the fertility rate dropped to less than 1. Some of the collected comments were labeled, and emotional levels were calculated through deep learning models. Through this study, we found that awareness of recruitment system conversion did not increase as the decrease in the fertility rate, and it was confirmed that people's interest is gradually increasing.

  • This paper aims to derive macroeconomic implications by analyzing the business cycle characteristics of the youth unemployment. The results of empirical analysis seem to show that youth unemployment appears to be relatively less correlated with business cycle compared to other age groups, and thus it is difficult to explain the recent steady increase in the potential labor force as a result of the business cycle fluctuation alone. Moreover, the alternative unemployment measures of the youth group showing upward trend were estimated to be co-integrated with output measures. This co-integrated trend increase suggests that unlike other age groups, youth may be influenced by structural factors inherent in Korea's economic growth path. The fact that the wage difference based on firm size has widened steadily since the Asian financial crisis and that the proportion of large companies that provide relatively high-quality jobs compared to major industrialized countries is significantly lower may be the evidence of the structural changes in Korean youth labor market. The results of above analysis may explain why the job search periods for youth has lengthened amid these structural changes.

  • This paper analyzed what determines affected FDI inflow of developing countries by using panel data from 65 lower-middle income and low income countries(Asia, Africa and Latin America). Empirical results showed that economic growth has a more positive impact on a middle income country than a lower one, and has a better impact on the Asian continent than others. Trade has similar effect on lower and middle income countries, respectively. ODA, however, has a negative effect on both sides, regardless of the continent. Industrial value added rate and labor force have a positive effect on FDI in low and middle income countries. Infrastructure was found to be a significant impact on FDI inflows in lower-middle income countries than in low income countries. There is no geographically significant difference except Africa.

  • The purpose of this paper is to summarize the development process of major science and technology manpower policies and to derive desirable future policy directions in the policy environment of a paradigm shift in supply and demand. To this end, first, the development process of the science and technology manpower policy, which was promoted in earnest from the 2000s, with the topic of resolving the phenomenon of avoidance of science and engineering majors, was examined, focusing on the basic plan for supporting science and engineering majors. Next, we summarized the main contents and implications of the change in demand for science and technology personnel caused by digital transformation and the supply shock of demographic decline, that is, the paradigm shift in the supply and demand of science and technology talents. Based on this, the core direction of the future science and technology manpower policy was suggested to create a human-centered science and technology research ecosystem that promotes the continued growth and inflow of human resources, so that can be the foundation for the training and utilization of excellent science and technology talents.

  • Going beyond the previous formulations of development theories, the present paper explores the effects other than political economy on quality of life in a rapidly developing country. The major analysis takes up the historical trend and nature of the developmental transformation that is partially a consequences of state structures and partially autonomous form it in South Korea. Also, it diagnoses developmental pathways for the future track by constructing a baseline model for state transition on the basis of power game between the state and civil society in the country. The results of the historical analysis show that civil society has been transformed in the course of confrontations and interactions between the state and nationalist social movement. The distinction between developmental(or bureaucratic authoritarian) and democratic state is presented to show that these are two qualitatively different aspects of state of state power, requiring separate analytical treatment. Furthermore, the state-centric approach which emphasizes the active role of the state at the sacrifice of societal fabric-constraining social conditions for quality of life - appears to be modified. On the contrary, the impact of civil society is transmitted both directly and indirectly via labor and ecological movement for quality of life, which is critical to the formation of the welfare state in the country. The prospect for sustainable development in Korea lies in providng and expanding quality of life in terms of the financial feasibility of the state through the public-private cooperation, and abstaining from drastic and radical commitment to welfare services as is the case with the European declines in welfare state, Further studies are needed to examine the interrelationships in different historical and cultural settings of developing counties to estimate a theory of quality of life and social justice.
