This study is try to do the empirical tests on the relationship among innovation cycle, investment cycle, and business cycle suggested in recent economic growth models. We apply co-spectra analysis to estimate dynamic correlations in the extraction HP filtered variables and first difference filtered variables in our data set. Our empirical results are; (i) an existing asynchronization between innovation cycle and investment cycle, (ii) in the long frequency, an existing positive correlation between innovation cycle and business cycle, (iii) in the short frequency, however, a finding the high negative correlation between the two cycle. Our empirical findings support the recent growth through cycle models and suggest some economic policy implementations for economic stabilization during a severe business cycle.

본 논문은 혁신클러스터의 수명주기에 관한 논의를 심화하는 연구이다. 이를 위해 국내 대표적인 혁신클러스터인 대덕연구개발특구의 성장과 발전 과정의 사례를 연구대상으로 한다. 본 연구는 선행연구를 통해 혁신클러스터 정책의 특징을 살펴보고 혁신클러스터 수명주기 이론에 기반하여 특정한 혁신클러스터가 성장 단계별로 어떠한 정책을 통해 구축되고 활성화되었는지의 현상과 각 주기별 유형적 특성을 진화론적 관점에서 고찰한다. 특히 대덕연구개발특구의 성장단계를 구분하고 각 단계와 발전과정에서 제도 및 정책의 변화를 실증적으로 분석한다. 본 연구결과, 첫째, 본 연구에서 대덕연구개발클러스터는 진화적 관점에서 잠재기, 출현기, 성장기, 성숙기의 단계(dimensions)적 특성을 가진다. 둘째, 대덕연구개발특구는 기본적으로 정부주도적 하향식 구조를 가지고 있어, 상당히 포괄적이며 유연한 우산정책적 특성을 가진 혁신클러스터 정책 구조(governance), 조치(measurements), 도구(tools)가 적용되고 있다. 셋째, 이와 같은 수명주기의 각 분면과 단계에서 혁신장애로 인식되는 점을 대상으로 정책적 기조를 재조정하면서 적응적 발전하는 것이 포착된다. 이성에서 혁신클러스터의 성장측면에서 구조적 접근보다 미세하게 정책이 적용되어야 하고 발전과정에서 변형(transformation)되어야 한다. 본 연구 결과를 통해 혁신클러스터의 진화론적 관점에서 각 단계별 유형적 특징 및 진화의 방향을 고찰하여 정부의 혁신클러스터 정책개입의 효과제고를 위한 시사점을 제안할 수 있다.

The industrial life cycle theory was extended to the product life cycle theory and the corporate life cycle theory, but a conceptual life cycle was presented, and quantitative empirical evidence for this was insufficient. It is intended to improve appropriate resource planning and resource allocation by quantitatively predicting the industrial cycle and its position (age) in the cycle. Human resources, tangible assets, and industrial output analysis were conducted based on 28 years of actual data of 39 industries in Korea by applying the Gompertz model, which is a population ecology prediction model. By predicting with the Gompertz model, the coefficient of determination R2 value was 97% or more, confirming the high suitability with the actual cumulative sales value of the industry. A numerical model for calculating the life cycle of each industry, calculating the saturation of input resources for each industry, and diagnosing the financial stability of the industry was presented. These results will contribute to the decision-making of industrial policy officers for budget planning appropriately for each stage of industry development. Future research will apply the numerical model of this study to foreign national industries, complete an inter-industry convergence diagnostic model (e.g. ease of convergence, suitability of convergence, etc.) for renewal of fading industries.

Purpose: This study aims to figure out the characteristics of corporate life cycle and resource input in terms of the sustainability diagnosis of pharmaceutical companies in Korea. Research design, data, and methodology: Using the Gompertz model under the assumption that companies have finite resources, this study tries quantitative interpretation of life cycle and resource input pattern for longevity companies with 25 years of experience among 158 pharmaceutical companies listed on Korean stock market based on maturity of revenue. Results: The study found revenue maturity through Gompertz model was statistically correlated with enterprise value. According to the life cycle analysis, more than 95% of 59 pharmaceutical companies were in the growth and maturity phase and have an average life cycle of 88 years and an average remaining life of 52 years. Regarding maturity profile of resource input, maturity of employees was generally high more than 60% and this meant there was jobless growth in Korean pharmaceutical industry. Conclusion: This study demonstrated there is a high statistical correlation between the maturity of a company's resource input and its revenue and enterprise value. It is believed that these results could be utilized as a basis for high fidelity function that predict revenue and enterprise value based on resource input information.

Purpose - This study aims to study the activation pattern of declining industries by applying the Gompertz growth model using available resources based on the theory of industrial life cycle, classifying declining industries among Korean manufacturing industries, and identifying resource input characteristics. Research design and methodology - This study was conducted by combining the Gompertz growth model that predicts the limit of output based on available resources under the industrial life cycle theory. Using Gompertz model, this study analyzed the life cycle of 39 Korean manufacturing industries from the perspective of domestic production, number of employees, and fixed assets Results - According to a life cycle analysis of 39 manufacturing industries in Korea, the computer, textile, and shoe industries were classified as declining industries. Among them, research on resource input characteristics on the shoe industry showed that domestic production and the number of employees decreased, while the proportion of domestic R&D personnel and the number of research departments gradually increased. Conclusion - Among the declining industries in Korea, the shoe industry is considered to revitalize the industry, that is, to extend the life of the declining industry by offshoring its production site and improving constitution with a "R&D center for global" support.

This study adopts diffusion of innovation theory and analyses product life cycle on two different information communication technology (ICT) products. One is telematics located on introduction and the other one is MP3 located on maturity. The analytical results were mixed. ordinary least square (OLS) result showed that adoption of MP3 player is affected by white noise error ($\varepsilon$) and telematics is influenced by innovation effect (p coefficient) rather than imitation effect (q coefficient) or white noise error. However, nonlinear least square (NLS) result showed that adoption of MP3 player is affected by imitation effect (q coefficient) rather than innovation effect (p coefficient). In addition, the ratio of imitation effect/innovation effect of MP3 player is larger than that of telematics.

Purpose: It can be said that the 21st century is the age of creativity. However creativity has been relatively less considered in comparison with control and continuous improvement in quality management. How to incorporate creativity into quality management is treated in this paper. Methods: The opposing characteristics of quality and creativity are examined, and the possible outcomes resulted from the conflict are reviewed. Previous researches on managing evolutionary and revolutionary changes are also examined. Results: Quality and creativity require each other although they have incompatible characteristics, and can be incorporated into the innovation cycle. Conclusion: Creative thinking tools such as SIT should be included in the quality training and education for the effective operation of the innovation cycle.

Alpha-ketoglutarate (AKG) is a key molecule in the Krebs cycle determining the overall rate of the citric acid cycle of the organism. It is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and inhibits protein degradation in muscles. AKG as a precursor of glutamate and glutamine is a central metabolic fuel for cells of the gastrointestinal tract as well. AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in the skeletal muscles and can be used in clinical applications. In addition to these health benefits, a recent study has shown that AKG can extend the lifespan of adult Caenorhabditis elegans by inhibiting ATP synthase and TOR. AKG not only extends lifespan, but also delays age-related disease. In this review, we will summarize the advances in AKG research field, in the content of its physiological functions and applications.
