  • This paper provides a new method of measuring the degree of technological progress which contributes to real economic growth based on Schumpeter's Trilogy. Using Microdata of Statistics Korea, the results of measuring and comparing the actual growth contribution of technological progress during the period 2003-2018 by the total factor productivity growth rate(growth accounting method), the R&D investment contribution rate, and the Schumpeterian innovation growth rate, respectively are as follows. First, the measurement of the real growth contribution of technological progress by the growth rate of total factor productivity and the growth rate of Schumpeterian innovation shows contradictory results. Second, when the growth rate of production is in a decreasing trend, the difference between the growth rate of production and the growth rate of total factor productivity increases compared to when it is in an increasing trend. Conversely, when there is an increasing trend, the difference between the growth rate of production and the growth rate of total factor productivity becomes smaller compared to when it is in a decreasing trend.. Third, the technological opportunity that affects the innovation growth rate, i.e., the contribution of R&D incentives to innovative growth is only 3.3%. The reason why this result is different from the existing perception of the contribution of technological progress to growth is that different entities are being measured while measuring the same term of technological progress. Therefore, the growth rate of total factor productivity should be used to measure macroeconomic efficiency, R&D investment should be used to measure the effectiveness of new technology supply, and the Schumpeterian innovation rate should be used to measure the economic impact of technological progress. The policy implications of the research results of this thesis are as follows: ① Transition from a policy of one-sided technology supply to a policy of convergence of technology supply and new technology demand support, ② Mission-oriented R&D policy and R&D policy that links national R&D with private R&D, ③ Reclassification of capital goods reflecting the degree of new knowledge.

  • The purposes of this study were to verify the longitudinal mediating effects of work-family balance on the relationship of role recognition in the family, marital intimacy and job satisfaction of married women, and to introduce longitudinal mediating effects by using latent growth curve modeling and autoregressive cross-lagged modeling. The subjects were married women from the third year data of the Korean Longitudinal Survey of Women and Family. Structural equational models were conducted with Amos ver. 21.0. The major findings are as follows. First, the result of the longitudinal mediating effects of latent growth modeling is the rate of change of work-family balance mediated between the rate of change of role recognition in the family and the rate of change of job satisfaction, and the rate of change of work-family balance mediated between the rate of change of marital intimacy and the rate of change of job satisfaction. Second, when using the autoregressive cross-lagged modeling, the more role recognition and marital intimacy of third year were the more work-family balance of fourth year, job satisfaction of fifth year. In both models, work-family balance mediated between role recognition in the family, marital intimacy and job satisfaction. Therefore, through this study, mediating effects of work-family balance can be found that there was a longitudinal effects.

  • The study was carried out to explore the effects of replacing wheat straw with fungal treated wheat straw as an ingredient of total mixed ration (TMR) on the growth performance and nutrient digestibility in Nili Ravi buffalo male calves. Fungal treated wheat straw was prepared using Arachniotus sp. Four TMRs were formulated where wheat straw was replaced with 0 (TMR1), 33 (TMR2), 67 (TMR3), and 100% (TMR4) fungal treated wheat straw in TMR. All TMRs were iso-caloric and iso-nitrogenous. The experimental TMRs were randomly assigned to four groups of male calves (n = 6) according to completely randomized design and the experiment continued for four months. The calves fed TMR2 exhibited a significant improve in dry matter intake, average daily weight gain, feed conversion ratio and feed economics compared to other groups. The same group also showed higher digestibility of dry matter, crude protein, neutral-, and acid detergent fibers than those fed on other TMRs. It is concluded that TMR with 33% fungal-treated wheat straw replacement has a potential to give an enhanced growth performance and nutrient digestibility in male Nili Ravi buffalo calves.

  • The purpose of this article is to measure sustainability of countries based on material flow approach by connecting fossil fuel vs. economy, and fossil fuel vs. environment, respectively. The focus of the article is to confirm where each country concentrates more between economic growth and environment. Even though most of countries exclaimed the growth harmonized between economy and environment, the empirical results proved that they had weight on economic growth over environment. Of three country groups, the sustainability in OECD countries was the lowest, whereas that of low income countries was the highest. It has been known that the main offenders of global warming are developing countries and backward countries, but emission of greenhouse gas per capita in OECD countries was higher and as a result, their sustainability was much lower than those of other countries. Accordingly, because the OECD countries have more responsibility for the emission of greenhouse gas, it is necessary that they have to bear a larger portion of emission reduction.

  • This paper investigates how firms adjust wages, employment and hours in response to demand shifts. It focuses on rigidities and asymmetries in such adjustments. Major findings are as follows. First, wage adjustments are fairly small compared with worker adjustments. Second, wage adjustments are asymmetric with respect to sales growth: there is no responsiveness of wage growth when sales are declining, while adjustments are significantly positive when sales are rising. On the contrary, worker adjustments are symmetric with respect to demand shifts. Third, while workers are linearly adjusted to the sales growth, some nonlinearity is observed in the wage adjustment. Fourth, hours are generally nonresponsive to demand shocks. Finally, union firms cut wages rather than workers in the face of negative demand shocks.

  • This paper attempts to investigate FDI Trade have been viewed a power affecting economic growth in Mongolia and five Central Asian countries(Kazakhstan, Uzbekistan, Kyrgyzstan, Kazakhstan and Turkmenistan) directly and indirectly using the Vector Error Correction Model. The results of empirical analysis based on data from 1995 to 2015 confirmed that FDI had a significant impact on economic growth in the rest of countries expect Kazakhstan and Turkmenistan, and Trade was not statistically significant for all countries. Accordingly we've come to below conclusion in consideration of the results of the statistics survey. It is urgently required to implement the policies on promoting foreign investment at first in order to recover economic decline though the international trading is considered important in developing the economics of developing countries. Especially, the landlocked countries, namely the countries having same border should focus on promoting the development of transport and freight forwarding systems between the countries, implementing the policies on trade relationships and foreign direct investments throughout the nation in consideration of the low- level of market economic conditions.

  • After the rapid growth of economics in South Korea 1960'1, the number of workers in the whole land in-creased day after day along with the growth of industry. As the growth of the third industry occurred quite rapid-ly, the rate of office workers went up high. Accordingly the business office has been changed the primary work-ing space and recognized the main space as much as the living space. As a result of conceptual change about working place, the business office has an important ef-fect on worker's liberal and psychological environment. In order to provide the office workers with the office work-ers with the suitable and convenient working environ-ment, Socio-psychological factors were first considered at the first stage of construction planning. In this paper, I would understand both how office workers take up their attitudes of Socio-psychological point according to the office type and what they claim for their office environment. This understanding offers us fundamental data in office plan. This paper starting from this purpose got the following conclusions. *Office workers are violated their hearing privacies rather than their visual privacies. They are dissatisfied with ensuring their own spaces and satisfied with their nature of domain. *In the feeling of satisfaction by office type, they are on the whole satisfied with their hearing privacies, their visual privacies, their own space, and the nature of do-main in the closed type and mixed type offices. In open type offices, their visual privacy is often violated. *In the property by individual, men feel more violated their hearing privacies than women. In the personal spa-se and domain, women are less stabilized psycholo-gically than men. *The analysis of the attitude by position, a man of po-sition is more violated his hearing privacy and does not understand each other. The common run of workers are violated their visual privacies and the nature of separa-tion.

  • The purpose of this study, reflecting the characteristics of recent R&D activities, where knowledge convergence and exchange and the growth of researchers are becoming more important, is to promote the growth of outstanding researchers by establishing a support system for researcher career development (intensifying expertise) and career fluidity (change in core research topics). Using the results of a survey of 548 researchers from government-funded research institutes, this study analyze environmental factors of research that promotes career development suitable for the growth of researchers after quantitatively verifying the effects of career development and career mobility on research outcomes. As a result of the analysis, it is more desirable to strengthen career liquidity after stable career development, but the human resources and career development support systems of research institutes are insufficient. Therefore, in this study, policy measures to support researcher career development and liquidity were proposed in four stages.

  • This paper illuminates the patterns of growth and declines in sizes of union membership in metal, chemical, financial, and auto transport sectors in three distinct periods during the last four decades from 1963 to 2003. This paper also calculates union densities in auto assembly, auto supply, and shipbuilding industries of the metal sector, cement, petroleum refining, and pharmaceutical industries of the chemical sector, private banking industry of the financial sector, and city bus industry of the auto transport sector. Such diversities in both sizes of union membership and union densities among sectors and industries turned out to be associated with attitudes and choices of employers and unions in interaction with sector- and industry-specific economic (growth stage and path), institutional (degrees of government intervention), and social (demographic features of employees and prevailing sizes of firms) environment. Such finding shows that theoretical reasonings on sizes of union membership and union densities across sectors and industries in advanced nations are also relevantly useful to analyze the Korean case.

  • The purpose of this study is: (1) to compare the awareness of inequality concept between Korea and other countries using the survey, (2) to identify whether several inequality measures, which have diverse concepts, are different in empirical aspect, and (3) to suggest the direction for the income distribution policy in Korea. The results of the survey has shown a surprising fact in that the majority of respondents do not agree with the basic assumptions outlined by Gini coefficient, which is the relative inequality measures that had been generally accepted in the past. These results are very similar to those of other countries. However, the major difference with other countries is that the Koreans feel that absolute income inequality-the income gap between the poor and rich, has increased more than relative income inequality, when all incomes of social members are doubled. From the result it is difficult to say that the bi-polarization index is different from Gini coefficient in statistical aspect although it has different theoretical background. The national development strategy should seek to promote "the pro-poor growth" since the change of inequality affect differently on the change of growth and inequality depending on whether the inequality change is relative or absolute.
