The purpose of this paper is to examine the structural change of Korean manufacturing industries and the differences of total factor productivity(TFP) between exporting industries and import substituting industries in Korean manufacturing industry from 1980 to 2013. The empirical results show that over half of total 13 industries have experienced changes of direction from import to export or export to import, which implies that there was a considerable structural change in Korean manufacturing industry. The output growth rates are higher in exporting industries than in import substituting industries. All industries employ more capital than labor during the period, which means that production methodology in Korean industries changes to a more capital intensive one. Finally, the growth rate of total factor productivity is higher in exporting industries than in import substituting industries, and it is also proved in panel regression analysis.

In this paper, in order to secure the safety and productivity of pine cone harvest, modeling and structural analysis of the hammering system for pine cone harvest drone that can easily access pine cone of Pinus koraiensis and collide with them to harvest them was performed. It calculate the equivalent stress for the structure of the hammering system and the yield strength of the applied material by applying the shear force of the stalk at which the pine cone is separated from the branch, and it is to verify the safety of the structure and propose an optimal design through appropriate factor of safety and design change. The shear force of the stalk at which the pine cone was separated from the branch was 468 N, and was applied to both ends of the hammering system. The yield strength of SS400 steel used in the hammering system is 245 ㎫, and the design change and structural analysis were performed so that the Von Mises stress could be less than 122.5 ㎫ by applying the factor of safety of 2.0 or more. As a result of the structural analysis of the frist modeling, the Von Mises stress was 220.3 ㎫, the factor of safety was 1.12, and the stress was concentrated in the screw fastening holes. As a result of the design change of the screw fastening holes, the Von Mises stress was 169.4 ㎫, the factor of safety was 1.45, and the stress was concentrated on the side part. As a result of the design change by changing screw fastening holes and adding ribs, the Von Mises stress was 121.6 ㎫, and the factor of safety was 2.02. The safety of the hammering system was secured with an optimal design with little change in mass. There was no deformation or damage as a result of experimenting on pine cone harvest by manufacturing the hammering system with an optimal design.

This paper explores the relatilonship between state level environmental regulations and stocking and location decisions in the U.S livestock and poultry industry (beef, chicken, dairy and hogs), Rather than conduct this analysis on a species by species basis, the overall size of the livestock industry(expressed in animal units) and the size of Industry found on large, medium and small operations by state (48) and over time (29 years), which is panel data analysis, Generally, regulations seem to be induced by the structural change of industry; when industry creates externalities, regulators try to address them with policy tools to internalize them, Written regulatory stringency may not effect behavioral change; rather the state's willingness to enforce regulations seems to have a measurable influence. However, in the presence of rapid structural change, industry location is affected by written regulatory stringency. Policy enforcement activity was shown to influence inventory decisions in general and larger operations were found to be more sensitive to willingness to enforce than smaller operations.

The aim of this paper is to grasp the impact of entrepreneurial activities of politician and business owner on regional industry amid the rising importance of entrepreneurship as the driver of structural change. In particular, it would help narrow the knowledge gap in empirical research by analysing the entrepreneurial spirit and motivation of the different trait of politicians and entrepreneurs that the relevant research is still insufficient. Through the case of politician' and business owner's entrepreneurship on the carbon industry growth of Jeollabuk-do and innovative start-up entering the lagging textile industry of Daegu, this study unearths the necessity of entrepreneurship, which has not been considered relatively much in the process of establishing regional industrial policies, thereby drawing the policy implication.

The UAV industry grows rapidly and the civil UAV market which preparing the commercial services is expected to accelerate the growth. The new opportunities from the technological progress and deregulation show two kinds of organizational structure in the UAV industry. The companies from the traditional aircraft industry and the other sectors like IT industry have different organizational structures of the value chains, supply chains and the regulatory policies which related with them. And from the isomorphism theory it is predicted that those structures will change and converge to certain similar homogeneous features as the UAV industry matures. The matured form will be resulted by the new regulatory policies about the airspace, certifications and the operation rules about the UAV and the future market size and growth speed are also affected by them.

In recent years, the knowledge service industry is getting much attention in terms of the role as new growth driver and employment creation sector whereas the overall potential growth rate in Korea has been slowed due to reduced investment and employment in manufacturing sector. This study examines how the knowledge service industry contributes to economic development and employment creation by analyzing the structure transition pattern of the knowledge service industry from 1995 to 2010 and suggests, based on these results, some policy implications for the industry's development. It turns out that the knowledge service industry greatly contributes to total production increase and employment creation during the period of 1995 to 2010. Special strategy for increase in labor productivity will be required for the knowledge service industry to contribute consistently as growth driver and employment creation sector since production increase rate and growth contribution level have been gradually decreased while employment growth rate and its contribution level have been consistently increased in the knowledge service industry.

This investigation was carried out in Liaoning, Shandong, and Shaanxi where classified most of their geological organizations into profit organizations, which means they must implement enterprise-oriented reform immediately. The valid 311 questionnaires were collected and used to verify the serial mediating model by AMOS 23.0. Results verified the crucial mediating effects of structural and psychological empowerment between external-focused organizational culture and openness for change. Adhocracy culture positively affects employees' openness for change through three indirect paths, including one mediator and two mediators. Market culture impacts individuals' openness for change through two indirect paths, one is through structural empowerment and another one is through two mediators. The findings provide managers in geological organizations with an empowering management practice model which could promote geological industry reform effectively.

X-ray diffraction technique was used to quantify change of cellulose crystallinity during refining. XRD data confirmed that fiber wall delamination was caused by the structural conversion of celluloses which occurred in a liquid medium during refining. The quantified crystallinity of celluloses in pulp fibers was closely associated with the change of fiber wall delamination, which was defined by measurement of fiber wall thickness. In particular, it was well recognized that low intensity beating showed a better response in the change of crystallinity than high intensity one. The decrease o cellulose crystallinity during refining considerably enhanced the improvement of interfiber bonding ability of a dried sheet.
