성과간에 차이가 발생하고 있다. 따라서 고객의 확보와 사용 확대를 통해 창출된 가치로부터 수익을 얻는 가치 전유(Value Appropriation)에 대한 전략적 관심이 증대되고 있다. 본 연구는 가치 전유 측면에서 인터넷 비즈니스의 성공 방안을 제시한다. 인터넷 비즈니스의 성공을 위해서는 더 많은 가치를 창출하는 것만으로는 부족하며, 동시에 그 가치의 더 많은 부분을 전유하는 것이 필수적이다. 인터넷 비즈니스에서 가치 전유의 특성을 분석하고 한국 포털 사업의 사례를 통하여 가치 전유의 방법을 도출한다. 인터넷 매체는 가치의 전유를 어렵게 하며, 특히 고객으로부터의 가치 전유가 매우 중요하다. 인터넷 비즈니스에서 가치 전유는 크게 '직접적인 유료화', '간접 수익의 확대', 그리고 '가치 창출에 고객의 참여 유도'의 측면에서 이루어지고 있다.

The innovation activity is an important factor for sustained growth in nations and firms. Particularly, the problem of appropriation of results of the innovative activity is very important for innovators since it enables them to enjoy the profits generated by their innovations. This study is intended to empirically analyse relative preference of patent and secrecy that is affected by characteristics of innovators and results of innovation using data from '2005: The Korean Innovation Survey' and Ordered Logit method. As a result of this study, the preference for a specific mechanism is clearly revealed in product innovation rather than process innovation. Also, in most research, questions results of analysis are equal to the previous studies and the nature of appropriation methods. However, the result of a research question based on sources of information is very different from previous researches. This study utilized more recent data than previous studies. This result reflects that existing patterns have been changed during recent period.

In this study, we have analyzed the impact of firm, innovation and industry characteristics on firm's appropriation strategy focusing of the relative preference of patents and trade secrets by using the Korea Corporate Innovation Survey 2005, 2010 and 2014 data. According to the analysis results, companies with characteristics such as venture, high-technology industry, receipt of public R&D subsidies, performing product innovation, high R&D expenditure, prefer patents to trade secrets relatively. However, firm size and R&D cooperation did not have a statistically significant effect on the relative preference. This shows that policy on appropriation system considering the industry characteristics may be more effective. Companies in the industries with a high market concentration showed that trade secrets are preferred, especially these characteristic was distinctly in small and venture companies. This means that the increase in strategic patent applications of the incumbent firms is able to restrict the patent activities in small and venture companies. Because the excessive increase in strategic patents is likely to constrain the innovation activities of small and venture firms ultimately, policy initiatives to limit the abuse of strategic patent applications is required.

In this study, in addition to non-technical innovation activities such as organizational innovation and marketing innovation, the purpose of this study was to verify through empirical analysis what mechanism appropriation affects the business performance of a company. Data were collected from the 2018 Korean Business Innovation Survey: Manufacturing Sector and used as analysis data. As a result of the analysis, it was verified through empirical analysis that non-technical innovation improves management performance, appropriability is affected by non-technical innovation, and acts as a mediating factor between management performance. Through this empirical analysis, it was derived that considering appropriation along with non-technical innovation on the recently studied non-technical innovation can be a meaningful study, and since securing such appropriation is an important factor in determining the business performance of a company. Companies need insight into the strategic use of technology protection measures to secure appropriation. As a limitation, it was limited to studies that verify that it has a mediating effect of non-technical innovation and appropriation, and it is considered that it is possible to develop a study that affects the management performance of a company through more various verification methods for future studies.

This study analyzes relationship between utilizing patents and trade secrets of firms empirically by using Koran Innovation Survey data. A number of prior theoretical studies have been discussed by assuming the patents and trade secrets used as alternative mutual relations. However, the use of patents and trade secrets can be used as a complementary and alternative methods generally based on a variety of firm and innovation characteristics. In this study, after controlling for nature of businesses, industry and innovation, the relationships between patent and trade secrets were analyzed by using 2005, 2008, 2010, 2012 and 2014 cross-sectional data. Prior to 2010, the relationship of patents and trade secrets was used as a complementary, while the result of 2014 showed that patents and trade secrets were utilized by firms independently. However, because we couldn't completely rule out the possibility that this result is caused by the difference between surveys, we performed a additional analysis. In conclusion, the independent relationship between patents and trade secrets may be caused by the increased number of patent applications and preference for the patent by firms since 2010.

오페론(operon)은 보통 미생물에서 다수의 인접한 유전자들로 구성된 그룹으로 하나의 유전자처럼 공통된 프로모터에 의해 전사되는 단위이다. 오페론을 구성하는 유전자들은 기능적으로 서로 유사하거나 같은 물질대사경로(metabolic pathway) 상에 존재하는 특징을 지니기 때문에 이들은 중요한 의미를 가지며, 미생물 유전체 분석에서 오페론을 구성하는 유전자들을 예측하는 것은 상당히 중요하다. 오페론을 예측하는 이전 연구들로는 이미 알려진 오페론의 특징인 유전자간 거리나 오페론을 구성하는 평균 유전자 개수 등을 이용하는 방법, 마이크로어레이 발현 실험을 이용한 방법, 전유전체(whole genome)들 간의 보존된 유전자 집합(conserved gene cluster)을 이용한 방법 그리고 물질대사경로를 이용한 방법 등이 있다. 본 논문에서는 COG 기능(function) 거리, 유전자 간의 거리, 코돈 사용빈도(codon usage) 그리고COG 기능 거리와 유전자간 거리를 같이 적용한 방법을 이용하여 오페론 예측을 위한 전처리 모델을 생성하였다 전처리 모델을 E. coli 전유전체에 적용해본 결과, 알려진 오페론들의 약 90%가 이를 포함하였다. 따라서 본 논문에서 제시한 전처리 모델은, 추후 오페론 예측을 위한 좋은 도구로 활용할 수 있을 것이다.

Designs in the modernism era were produced for the purpose of standardization of items and devices centered on efficiency and functions, and the will of design consumers in the industrial era, when consumption exceeded production, was limited to the objects of consumption. But, after the post-modernism era, design consumers have started to entail acts of exclusive possession such as participation in the design idolization, partipation, tuning, control and parody as design consumers in the digital environment do not passively accept what is given to them anymore, and aggressively intervene in the process of design production and management. It is expected that designs will change from the system in which only professionals can produce and manage its production to that of cooperating with consumers to produce designs, and various forms of consumers' exclusive possession will change all sort of design environments including production methods surrounding design products and distribution. Therefore, this study seeks to induce efficient design production by understanding changes of consumers' cultural environment resisting standardization and structuralization with smoothy perception between producers and consumers through classification of consumers' appropriation into de-construction, re-signification and self-identification.

This study empirically examined how a firm size affects the determinants of innovative activities using the data of the Korean Innovation Survey (KIS) 2016. With data from 2,003 firms in the manufacturing sector, we performed logistic regression analysis and zero-inflated negative binomial regression analysis. R&D expenditure and patent applications were used as proxies for innovative activity. The independent variables included the firm's characteristics variables such as the firm's age, tech-level industry, RDemp (R&D employee ratio), venture, export, and industrial characteristics variables such as networking, appropriability, and spillovers. The empirical findings are that there are some differences in firms' innovative activity determinants among the firms' size groups. Next, strategic appropriability has negative impacts on small firms' R&D expenditure and medium-firms' patents. Networking is an important determinant of innovative activity for all firms, except for large firms. Furthermore, in deciding R&D activities, small and medium-sized firms were significantly influenced by industrial characteristics as compared to that of large firms. Our findings suggest some R&D promotion policies. Policies fostering firms' technological interaction would allow firms to take advantage of technological spillovers and thus raise the probability of investing in R&D.
