The theories of cultural evolution hold subtly or clearly different stances about definition of culture, pattern of cultural evolution, biases that affect cultural evolution, and relationship between culture and organism. However, the cultural evolution theories have a common problem to solve: As the evolutionary theory of life tries to explain the early steps and the origin of life, the cultural evolution theories also must explain the early steps of the cultural evolution and the role of the human capability that makes cultural evolution possible. Therefore, explanations of the human's unique traits including the cultural ability are related to determine which one is the most plausible among many cultural evolution theories. Theories that tried to explain human uniqueness commonly depict the coevolution of gene (organism) and culture. We will explicitly call the niche construction theory and the dual inheritance theory the 'gene-culture co-evolutionary theory'. In these theories, the most important concept is the 'concept of positive feedback'. In this paper, we distinguish between core positive feedback and marginal positive feedback, according to whether the trait that the concept of positive feedback explains is the trait of human uniqueness. Both types of positive feedback effectively explain the generality of human uniqueness and the diversity of human traits driven by cultural groups. However, this positive feedback requires an end, in contrast to negative feedback which can be continued in order to maintain homeostasis. We argue that the co-evolutionary process in the gene-culture co-evolutionary theories include only the positive feedback, not covering the cultural evolution after the positive feedback. This thesis strives to define the coevolution concept more comprehensively by suggesting the potential relationships between gene and culture after the positive feedback.

This is a research thesis on the development of a monitoring and diagnosis device that prevents the risk of an accident through monitoring and diagnosis of a modular Main Circuit Breaker (MCB) using Vacuum Interrupter (VI) for Korean high-speed rolling stock. In this paper, a comprehensive MCB monitoring and diagnosis was performed by converging vacuum level diagnosis of interrupter, operating coil monitoring of MCB and environmental temperature/humidity monitoring of modular box. In addition, to develop an algorithm that is expected to have a similar data processing before the actual field test of the MCB monitoring and diagnosis device in 2023, the cluster analysis and factor analysis were performed using the WEKA data mining technique on the big data of Korean railroad transformer, which was previously researched by Tae Hee Evolution with KORAIL.

The present study aims to evolve the value cycle of e-business through value co-creation during the Coronavirus pandemic. The population of the study is experts consisting of university professors in the fields of marketing management, e-commerce, and managers of organizations and companies in Iran. Using the snowball sampling method, 50 of them were selected as the sample. This study employs the factor analysis method and structural equation modeling (SEM) approach for identification of the factors. The findings of this study reveal that 10 factors affect the evolution of the value chain into the value cycle, including customer relationship management, e-literacy, value co-creation, e-readiness, and integrated value creation, the logic of service dominance, shared value creation, virtual culture, e-trust, and network economics. Despite the difficulties that COVID-19 has created for businesses worldwide, the evolution of the e-business value cycle through value co-creation in the Coronavirus pandemic can be considered as a positive aspect of the pandemic. In fact, with more pandemics and more customers turning to e-businesses due to the co-creation of customer value, e-businesses can cover their weaknesses and improve their strengths by engaging customers and receiving their feedback, thus transforming their value chain into the value cycle.

본 연구의 목적은 문화행정과 예술경영 두 분야의 영역이 중복 적용되는 현장에서 그 추구하는 가치와 역할체계의 정립을 전문가조사를 통하여 시도하고, 공공부문과 민간경영부문에서 두 영역이 맥락의 차이를 이해하게 하며 예술의 발전에 기여할 방향을 제안하는 것에 있다. 두 분야의 공통점과 차이점, 선행연구 고찰을 통하여 7개의 가치를 선정하고 각 가치의 하위지표를 정하였다. 이를 제주지역 전문가를 대상을 설문조사를 하여 AHP 기법을 이용하여 우선순위를 분석 하였다. 분석결과를 바탕으로 가치 간 우선순위로 영역의 범위를 설정하고, 하위지표 간 우선순위로 체계를 정립하였다. 문화행정은 공공성, 형평성, 투명성의 영역을 기본으로 하며 예술경영은 생산성, 공공성, 대응성을 기본영역으로 한다. 이를 바탕으로 문화행정은 지역문화의 보존과 활용, 문화의 공진화, 문화예술교육의 확대에 대한 체계에 집중할 필요가 있으며, 예술경영은 목표달성의 정도, 투입대비 산출의 정도, 지역문화의 보존과 활용에 대한 체계에 집중할 필요가 있다. 또한 제주지역에서는 문화의 공진화와 지역문화의 보존과 활용에 대한 공통적인 지향점을 갖고 체계를 정립할 필요성이 있음을 알 수 있었다.

The purpose of this study is to investigate the evolution of regional tourism resources from the perspective of business ecosystem network. A regional tourism structure changes due to various factors such as natural resources, facilities, festivals and events, public resources, and etc. An exploratory analysis was conducted to examine the interaction between resource characteristics and alliance complexity in the regional tourism industry. In the process, the duality of technology provides an insight into the interaction among several players within an alliance network which include regional attractions and tourism industry. As a result. we identified four types of tourism alliance network: functional, organizational, resource-oriented, and artificially-allied. The managerial implications are also discussed.

This paper examines the evolution issues of regional tourism resources in complicated and networked industry the perspective of co-evolution types and dualism. Regional tourism structure has been changing more and faster according to various attractions and internal and external environment; natural resources, facilities, festivals and events, drama and movies, and public resources, etc. This paper approaches Olikowski's dualism perspective as a theoretical view about the alliance network between region's attractions and tourism industry in Korea. Exploratory analysis was explained the dualism cases performed on the matrix between resource characteristics and alliance complexity on human resources based on regional tourism industry.

해조류 중 갈조류인 미역으로부터 분리당화발효(SHF)를 위한 전처리 및 효소당화를 검토하고, 기존의 분리당화발효(SHF)를 개선하기 위해 공배양발효(co-culture)를 수행하였다. 비순치 효모와 고농도 mannitol에 순치(adaptive evolution)한 효모를 이용한 공배양발효를 실시한 결과 발효 72시간에 12.2 g/l의 에탄올과 에탄올 수율($Y_{EtOH}$) 0.41을 나타내었다. 이러한 기존의 분리당화발효(SHF)를 개선한 공배양발효를 통해 에탄올 생산 수율이 0.23에서 0.41로 35.2% 증가하였으며, 에탄올 발효시간도 108시간에서 72시간으로 33.3% 감소하였다. 이러한 연구결과는 해양 바이오매스인 해조류로부터 바이오연료 생산과정에 있어 유용한 정보를 제공하는 것으로 판단된다.

Temporal changes of cell growth pattern and intracellular content of $\beta$-D-glucans were investigated with off-gas data in Agaricus blazei culture where glucose was intermittently fed. It was observed that the time point of carbon source depletion coincided with the point of sudden drop in the carbon dioxide evolution rate (CER), and that the sole supplementation of glucose was not enough to maintain active cell growth and glucan content. On the other hand, when yeast extract, a typical nitrogen source, was supplemented together with glucose when the CER suddenly dropped because of carbon source depletion, an active cell growth could be maintained until the end of the culture and the glucan content did not decrease with culture time, significantly enhancing glucan productivity.

Quadrupole mass spectrometer를 이용한 발효 배기가스의 분석을 통해 세포의 증식을 on-line monitoring하고자 model 균주로 Candida utilis에 대해 연구하였다. Quadrupole mass spectrometer와 interface된 16-bit 개인용 컴퓨터 (IBM PC-AT)에서 산소 소비속도(OUR)와 이산화탄소 발생속도(CER)를 on-line 계산할 수 있었고 계속해서 이들 계산치로부터 세포농도와 증식속도 및 비증식속도를 계산하였다. 계산된 값들은 실험적으로 측정한 세포농도 및 비증식속도와 잘 일치함을 알 수 있었다.

Territoriality and privacy are known to be basic human instincts that have made today's cultural evolution possible. However there are also cultural differences in the expressions and meanings of territorial and privacy behaviors. Currently with the emerge of non-territorial workplaces office workers are deprived from what used to be their territory and force to share with co-workers leading confusion and stress. Therefore many research has be conducted on territorial issues but unfortunately little is known on Korean cultural concept of territoriality and privacy. Eyen though Korean society has been rapidly westernized during the 20th century, traditional culture still is a major influence on Korean's concept and use of space. This study explores and investigates the concept of territoriality and privacy and how they are expressed in traditional Korean housing focused on high level society between 17th and 19th century. Thus hope make a small contribution in designing unique and culture based interior spaces.
