  • This paper investigates the effects on Korean exports of demand in developed economies, and how these effects have changed since the global financial crisis. As a measure of import demand, we use import intensity-adjusted demand to take into account heterogenous import intensities across components of aggregate demand. Our estimation of a dynamic panel regression model reveals that Korea's exports to the G7 countries were elastic with respect to the import demand of these countries until the global financial crisis, but have shifted to become inelastic since. Furthermore, we separately estimate the effects of the different components of the G7 countries' aggregate demand (private consumption, public consumption, investment and exports). The results show that the decrease in private consumption in the G7 countries during the crisis had a significant impact in causing the decline in Korea's exports to them, but that the increase in their public consumption since the crisis has had a significant effect on driving increased Korean exports to them. The effects of the G7 countries' exports on Korea's exports to them remain positive and significant during both the pre- and post-crisis periods. The effects of the G7 countries' investments on Korea's exports are also positive and significant, but the positive effect has weakened since the crisis. Our findings suggest that the overall effect of changes in the G7 countries' import demand on Korea's exports to them has weakened compared to the pre-crisis period.

  • Global climate change brings environmental quality sensitivity, especially in developed countries. Developed countries use non-renewable energy sources intensively both in their own countries and in other countries, they make productions that cause an enormous rate of increase in CO2 emissions and unsustainable environmental costs. This has increased the interest in environmentally friendly alternative energy sources. The aim of this study is to investigate the impact of nuclear energy consumption and technological innovation on environmental quality in G7 countries using annual data over the period 1970-2015. The Panel Threshold Regression Model was used for the analysis. Empirical findings have indicated that the relationship between nuclear energy consumption and carbon emissions differs according to innovation for nuclear power plants. It was also concluded that nuclear energy consumption reduces carbon emissions more after a certain level of innovation. This result shows that the increase in innovative technologies for nuclear power plants not only increases energy efficiency but also contributes positively to environmental quality.

  • Nowadays communication network is steadily changing from a main body of telephone to a network which is creating new services such as multimedia etc. Jhis article introduces a bud of new service and new network which are able to sustain the above service. Including Korea, world advanced countries have been digitatizing their network with N-ISDN (narrowband ISDN) by e.g. 64K b/s and 1.5M b/s. New service by N-ISDN are extraordinary, though it can not solve all kinds of services. To solve these problems, a solving platform should be constituted. B-ISDN(broadband ISDN), as a platform has to be built to deal with almost all uinds of services, whatever the communication speed, communication mode or communication quality may be. Korea Telecommunication Authority(KTA) opened the narrowband ISDN(N-ISDN) at the end of 1993. This was one step previous opening of the broadband ISDN(B-ISDN) service scheduled to be rendered in 2001. B-ISDN, receiving and transmitting by far more information with high speed than the N-NSDN does, is one of G-7 Progects which the Korean government is driving foreward to raise the national scientific power to seven advan ced countries. This is also linked with an extremely high speed information network scheduled to be built by the Ministry of Communications in 2015.

  • Although the incidence of breast cancer in Asia remains lower than in North America, Western Europe, and Oceania, rates have been increasing rapidly during the past few decades, and Asian countries now account for 40% of breast cancer cases diagnosed worldwide. Breast cancer mortality has also increased among Asian women, in contrast to decreased mortality in Northern America, Western Europe, and Oceania. These increased rates are associated with higher prevalence of breast cancer risk factors (e.g., reduced parity, delayed childbirth, increased obesity) that have accompanied economic development throughout the region. However, Asian regions (western, south-central, south-eastern, and eastern) and countries differ in the types and magnitude of changes in breast cancer risk factors, and cannot be viewed as a single homogeneous group. The objective of this paper was to contrast the heterogeneous epidemiology of breast cancer by Asian regions and countries, and to suggest potential avenues for future research.

  • Expectations for wireless communication technology are rising as a base technology that promotes innovation in various industries in line with the paradigm of digital transformation in the 21st century beyond the stage of being used only for communication service itself. In this study, in order to compare 6G technological competitiveness between Korea and leading countries, technological competitiveness was confirmed through PFS, CPP, and network analysis based on GaN Integrated Circuit patent data. Korea's 6G technological competitiveness was 0.62 in PFS and 3.93 in CPP, which were 32.8% and 19.9%, respectively, compared to leading countries. In addition, as a result of network analysis, the collaboration rate in the 6G field was 7.2%, and the collaboration ecosystem was very insufficient in most countries. In contrast, it was confirmed that Korea, unlike leading countries, has established a small-scale collaboration ecosystem linked by industry and academia. Thus, it is necessary to establish a strategy for 6G communication technology at the national level so that communication technology can be advanced based on a relatively well-established collaborative ecosystem.

  • Purpose: Global economic integration has provided good opportunities and conditions for the development of foreign direct investment in Finances. Therefore, this paper attempts to explore what determines foreign direct investment in Finances of Organization for Economic Co-operation and Development (OECD) countries. Research design, data and methodology: This paper employs the panel data over the period 2005-2017 and uses the random effect model to estimate this proposition. Results: The results indicate that the foreign direct investment in services, growth rate of GDP, interest rate and saving are positively related with foreign direct investment in finances. Conversely, the growth rate of wage and fluctuation rate of exchange rate are negatively related with foreign direct investment in finances. Moreover, the results verify that the effect of these variables on foreign direct investment in finances is different before and after 2008 (global economic crisis). In addition, the results also manifest that the regional effect exists. Namely, the effect of these variables on foreign direct investment in finances between G7 countries and G20 countries exist significant difference. Conclusions: Those variables used in this paper are related with foreign direct investment in Finances of (OECD) countries.

  • Between 2010 and 2012, former Bank of Japan Governor Shirakawa argued, in series of speeches, that Japan's economic performance, when compared to that of other G7 nations, was stronger after 1990 than appreciated by the critics. In May 2012, Nobel prize-winning economist and Princeton University professor Paul Krugman echoed a similar sentiment in a Financial Times interview. This analysis expands on these assertions and asks to what extent they are supported by cross-section data for the G7. As reviewed below, to date, no idiosyncratic explanation has arisen to explain the Japanese slowdown-perhaps this is the correct explanation: the slowdown in Japan, once adjusted for demographics, is less severe than in other G7 countries and, as recently noted by Eichengreen, Park, and Shin (2015), TFP growth in a number of other nations followed similar patterns. Focused on labor productivity, far from a laggard, Japan's performance ranks near the best in the G7.

  • Many countries set growth engine technologies and industries for economic growth and job creation. Each country always wants to know their technological or industrial position in the world in these industries. This study aims at identifying the worldwide position of 19 growth engine industries defined in Korean government. The methods are quantitative by counting the number of startup companies in the world. The ORBIS database was used to extract the number. Therefore, this article may be the first research for the world appearance of growth engine industries and its comparison between world and G7, and between G7 countries. Also, this may be the first study using the ORBIS database on the analysis of certain technology industries. Further, we showed a method to identify world features of technology industries.

  • Three-day dietary records data from 237 college students(male 65, female 172) were used as the basis to estimate total dietary fiber(DF) intake of Korean adults & to investigate the major food sources of fiber. Mean daily DF intake of the subjects was 15.2$\pm$3.7g range being 7.5-34g When related to energy intake women consume more DF(7.7$\pm$1.5/1000kcal) than men(6.8$\pm$1.7g/1000kcal) Mean daily crude fiber(CF) intake of the subjects was 6.2$\pm$2.4g The mean DF:CF ratio for the subjects was 2.5$\pm$0.5 indicating that DF intake is 2-3 times of CF intakes The intakes of the two measures of fiber were highly correlated(r=0.791) The major food sources for DF in Korean are vegetables cereals and fruits and 14.3% respectively In comparision with limited international data on the DF intake by adults DF intake by the subjects was similar to those of developed countries. Present study indicates that DF intakes of the subjects are considerably lower than recommended level and they need to consume more DF than the present level.
