  • By analyzing the impact of oil prices on economic growth, this study has shown a new insight into the link between oil price inflation and economic growth. The primary goal of this study is to determine if oil prices are pro-growth or anti-growth. To provide empirical proof, the series data for both the core and control variables from 1972 to 2020 was used to justify the association on empirical grounds. To account for the presence of a unit root, the Augmented Dickey-Fuller Test was used, and after making the series compatible for co-integration, the Autoregressive distributed lag model was used to determine the empirical estimate. Additionally, the empirical models were used to diagnose heteroscedasticity and autocorrelation. The reference point model reveals that in developing nations like Pakistan, economic growth is anti-growth with an increase in prices, and it responds negatively to economic growth in the long and short run. As a result, oil price inflation in Pakistan fails to have a significant beneficial impact on economic growth in both the long and short run, but it does raise the general price level in the economy.

  • Although there have been studies regarding the separating policy of dispensary and medical practice, little study have provided a concrete empirical evidence to what extent the policy objectives are achieved. In this paper, we try to provide empirical evidence whether the policy separating dispensary from medical practice achieved the policy objectives, which representatively are reducing the mis-use or over-use of anti-biotic prescriptions and medicines, and decreasing the government spending for the cost of pharmaceutical support. By comparing the average of the rate of change of the number of medicines prescribed, the rate of anti-biotics prescribed, and the government spending for the cost of pharmaceutical support between the areas where the separation policy was implemented and the exceptional areas, we concluded that it is difficult to conclude that the policy separating dispensary and medical practice achieved its policy objects, as it first announced to achieve in the introduction of the policy in 2000. However, the limitation of this study is that the data, that can thoroughly analyze the effect of separating policy of dispensary from medical practice, cannot be collected as expected. Hence, we could not use a parsimonious empirical model to evaluate the effect of the policy introduced in 2000. Rather we used a simple statistical method to extract enough empirical evidence fro m the data available. In the near future, we would expect to see more research that analyze the exact effect of policy separating dispensary and medical practice with concrete empirical model using more sophisticated dataset.

  • The purpose of this study is to develop the diagnostic indices system that can be applied to the evaluation of rural village level, because the indicators developed in many existing studies were mostly consisted of statistical data in higher level than rural villages as well as those were difficult to apply to rural village level empirically. In order to develop the empirical diagnostic indices system, which has 52 indices with 7 categories, this study not only classified the kind of rural village facility and the regional development project of government, but also surveyed the specialist opinion with Delphi method. Especially, this study standardized the all diagnostic indices with positive value to remove the indices with negative values. Finally, the results that the study applied the empirical diagnostic indices to the 15 sample villages of Jinan-gun and Cheongyang-gun showed that there was the applicability of the indices system in the village level.

  • The domestic fashion industry of the middle and late 20th century emphasized the importance of a standardized design process; however, the values of differentiated brand individuality have become increasingly important with the qualitative·quantitative growth of designer brands. Therefore, paying attention to designer individuality (or a differentiated element of a designer brand growing up in the domestic fashion industry) this study reestablished factors of the designer brand individuality. An in-depth interview was conducted with 13 designers and consumers for empirical analysis. In order to identify concepts of designer individuality based on the theory of the brand personality by Aaker along with precedent studies, the study devised a theoretical frame to explain a conceptual structure of designer brand individuality as well as reestablish its factors as the designer individuality, design and non-design factors through empirical research. Empirical research derived the designer individuality factors as an external designer image, designer taste, design philosophy and designer personality. Design factors were derived as concept, working process and method, style and formativeness. Non-design factors were also extracted as wearing experience, wearer image, lookbook image, fashion shows and exhibitions. It is meaningful that little empirical research has been conducted on domestic fashion designers who actually run designer brands and that this study helped understand designer brands through a new approach called designer individuality.

  • The importance of service quality in any service industry cannot be disputed. Shippers have increased expectations concerning the quality of shipping service they receive and carriers are struggling to meet these expectations. This struggle between shipper and carriers would suggest that there is room to improve much more understandings of how shipper define shipping service quality in the carriers' perspectives. This is an empirical investigation and study on the measurement of customer response and service quality as perceived by customer in the international transportation logistics system. The purpose of this study is to clarify factors of shipping service quality on the basis of service marketing concept. In order to fulfill the objectives, this paper combined research tools that include both empirical study and documentary research. Data was gathered from 132 freight forwarder by the use of questionnaire. In this study, the established hypotheses were generated on the basis of the service quality evaluation model(SERVQUAL, SERVPERF, and EP) and Gap model.

  • The purpose of this study is to estimate hourly Asian dust emission flux in springtime by using the optimized Weather Research Forecasting model (WRF) in order to accurately predict the horizontal flux of Asian dusts. Asian dust emission flux using 5 empirical formulas such as US EPA, Park and Inn, Wang, The Goddard Chemistry Aerosol Radiation and Transport (GOCART) and Dust Entrainment and Deposition (DEAD) were calculated and compared by using classified land-use types and size distribution at various locations in China and Mongolia together with the hourly meteorological elements of the WRF model. As a result, the empirical formula in US EPA among them, which was considered the various conditions such as vegetation, soil type and terrain, was better than the other 4 empirical formulas. However, these formulas were adjusted hourly and vertically in time and space because there was different order and time resolution of dust emissions from original empirical formulas.

  • This study proposes an empirical formulation to predict the maximum deformation of offshore blast wall structure that is subjected to impact loading caused by hydrocarbon explosion. The blast wall model is assumed to be supported by a simply-supported boundary condition and corrugated panel is modelled. In total, 1,620 cases of LS-DYNA simulations were conducted to predict the maximum deformation of blast wall, and they were then used as input data for the development of the empirical formulation by regression analysis. Stainless steel was employed as materials and the strain rate effect was also taken into account. For the development of empirical formulation, a wide range of parametric studies were conducted by considering the main design parameters for corrugated panel, such as geometric properties (corrugation angle, breadth, height and thickness) and load profiles (peak pressure and time). In the case of the blast profile, idealised triangular shape is assumed. It is expected that the obtained empirical formulation will be useful for structural designers to predict maximum deformation of blast wall installed in offshore topside structures in the early design stage.
