This study aims to analyze determinants and complementarities of the technological innovation protection mechanisms of Korean manufacturing firms. The results of the inter-industry comparison show that there are differentiations of the determinants among industries. Independence between legal and strategic protection mechanisms is found in the high technology industry, whereas complementarities exist between them in the low technology industry. It implies that the firms should take into account their endogenous and exogenous factors to choose appropriate combinations of the mechanisms when they build up their innovation protection strategies. This study expects to contribute to establishing technological innovation protection strategies in manufacturing industry.

This study is to analyze the impact of the absorptive capacity and information technology (IT) on firms' innovation. The absorptive capacity is measured by R&D investment intensity, R&D manpower concentration, and the firm's size. We try to see the interaction effects between the absorptive capacity and IT usage on firms' innovation. We also look into the differences of the impacts between manufacturing industry and service industry as well as IT industry and service industry. We found that IT and R&D intensity have stronger interaction effect on innovation in manufacturing industry than in service industry, which shows that IT plays a more important role in the accumulation of knowledge in R&D activity in manufacturing industry. Contrarily, in service industry, IT and R&D manpower concentration has significant interaction effects on innovation. This means that the role of IT in service industry is sharing knowledge and experiences among employees in service industry. The interaction effect between firm's size and IT has positive impact on innovation in manufacturing industry, while it has negative impact on innovation in service industry. Finally, we found that the interaction effect is statistically significant in non-IT industry, while it is not statistically significant in IT industry.

As culture technology is recognized as the important element of national industry, the necessity of the related policy development for enhancement of culture technology is magnified. In this study, we use conjoint analysis to investigate how the researchers from industry and academia think differently on the importance of several attributes in government-supported culture technology research project such as research period, size of research fund, inter-affiliated research requirement and interdisciplinary research requirement, and preference on those attribute levels. Also, we describes how a simulation experiment is designed to simulate participation shares of four alternative hypothetical research project profiles. This study will help establish the more effective policy of the national research program by understanding the preferential differences between industry and academia on the research project attributes.

본 논문에서는 연도별로 정유 부문의 경제적 파급효과를 비교분석하고자 한다. 한국은행에서 발표한 1990년부터 2012년도까지의 산업연관표를 이용하였다. 산업연관분석 분석모형 중 수요유도형 모형을 적용하되, 정유 부문을 외생화하여 분석함으로써 자기부문에 대한 효과와 타 부문에 대한 효과를 구분하였다. 정유 부문의 생산유발효과, 부가가치 유발효과, 취업유발효과를 정량화하고 연도별 추이를 살펴본 결과, 생산유발효과의 경우 1993년도부터 2008년까지 감소추세를 보이다가, 2009년도부터 2012년까지 일정한 수준(1.1912, 2012년 기준)을 유지하는 것으로 분석되었다. 그리고 부가가치 유발효과의 경우 1990년에서 1998년까지는 상승추세를 보이다가, 1998년 이후로 는 꾸준히 하락하는 것으로 나타났다(0.1174, 2012년 기준). 취업유발효과는 1990년부터 2008년까지 꾸준히 감소추세를 보이다가, 2010년부터 1.300(명/10억원) 이하의 수준에서 유지하고 있다. 이러한 분석결과는 과거와 비교하여 현시점의 국내 석유 산업을 객관적으로 평가할 수 있다는 점에서 의미가 있으며, 이러한 정량적 정보는 향후 석유산업에 대한 각종 경제적 파급효과를 예측하는데 유용하게 활용될 수 있다.

Background : Mutual understanding between North and South Korea is essential for the engagement of Inter-Korean exchange and cooperation. However, the two Koreas have been divided for 70 years where Korean evolved differently within the two countries. This created a gap in the most basic foundation for mutual understanding, language. Fostering exchange and cooperation in the traditional medicine field requires a higher understanding of the specialized traditional medicine terminologies. Objectives : The purpose of this study is to formulate a future management plan for the "Comparative Terminology of Korean Medicine in South and North Korea," providing a foundation for standardizing Korean medicine terminology of the two Koreas. Methods : The study collected case studies of Korean medicine terminology management and standardization from government and international organization websites and documents. It provided future terminology management strategies based on this data. Results : The project for the standardization of Korean medicine terminology between North and South Korea can be divided into 4 stages according to the level of exchange and cooperation. The first step is to "establish a foundation for terminology standardization." The second step is "term comparison." If the exchanges and cooperation between North and South Korea, the third step will be to promote the "terminology standardization" project through Inter-Korean dialogue. Finally, after incorporating discussion on terminology standardization, the Inter-Korean Medicine Terminology can be published. Conclusions : This requires a system to support and facilitate Inter-Korean medicine exchange and cooperation. It is important to provide a support system that can provide results in a timely fashion by training relevant experts, collecting data and information, communicating with experts in the industry, academia and research institutes. This system will be able to ensure the continuity of the terminology standardization project.

Seismic fragility was assessed for non-seismic reinforced concrete shear walls in Korean high-rise apartment buildings in order to implement an earthquake damage prediction system. Seismic hazard was defined with an earthquake scenario, in which ground motion intensity was varied with respect to prescribed seismic center distances given an earthquake magnitude. Ground motion response spectra were computed using Korean ground motion attenuation equations to match accelerograms. Seismic fragility functions were developed using nonlinear static and dynamic analysis for comparison. Differences in seismic fragility between damage state criteria including inter-story drifts and the performance of individual structural members were investigated. The analyzed building had an exceptionally long period for the fundamental mode in the longitudinal direction and corresponding contribution of higher modes because of a prominently insufficient wall quantity in such direction. The results showed that nonlinear static analyses based on a single mode tend to underestimate structural damage. Moreover, detailed assessments of structural members are recommended for seismic fragility assessment of a relatively low performance level such as collapse prevention. On the other hand, inter-story drift is a more appropriate criterion for a relatively high performance level such as immediate occupancy.

The purpose of this study is to examine by which correlation the pluralistic phenomenon in text is functioned in comparison with hair style and fashion in collection. As a result, the pluralistic image in text, which was shown in modern fashion, was indicated to be pluralistic phenomenon by gender, T.P.O, coordination, and material. The pluralistic image in text for hair style can be known to have been indicated to be the pluralistic phenomenon in text for gender and to be the pluralistic phenomenon in text according to material and cultural category. As for a method of this study, it did put limitation on the part that is shown in the fashion collection from 2001 to 2007, analyzed hair-style features centering on photos, which were extracted from style.com, the online site of specializing in fashion, and carried out a literature research side by side with the theoretical background on intertextuality. The analysis in work according to the pluralistic phenomenon in text made it possible for looking at with a new sight differently from the recognition in the past, and opened the potentiality for being able to understand lots of strange representations, which have been impossible so far. The process of imitating and reconstructing each text according to compositional principle led to possibly knowing the necessity of an artist's ability that can implement the originative world.
