This paper aims to examine the evolutionary dynamics of the Korea's footwear industry by adopting evolutionary perspectives. To explain the evolutionary dynamics of an industry, evolutionary perspectives have paid a particular attention to exploring a variety of factors for influencing the evolution of the industry, such as the selection and imitation of the firm, the mechanism of firm's entry and exit, technological characteristics and innovation processes. The majority of existing research tend to explain that the decline of the Korea's footwear industry since 1990 was mostly due to the rapid rising of wage and the structural changes in labor-intensive industries. On the contrary, this paper attempts to explain the decline of the Korea's footwear industry, in terms of the path of selection and imitation, the dominant technological paradigm, regulatory frameworks and the meso trajectory of industry evolution. This paper concludes that the decline of the Korea's footwear industry since 1990 was appeared as a result of the evolutionary selection processes of the firms in order to adapt to changes in the environment of competition and the regime of market selection in the global footwear industry.

The cooperative network structure influences the academic performance of the research institute. In particular, South Korea's Government-Funded Research Institutes(GRI) need to establish an efficient cooperative system as a leading national R&D implementer. This study applied the Small World structure, which has been discussed as an efficient network structure, and the centrality of representing the characteristics of nodes to the cooperative network of GRI in Korea. Based on the SCIE published data from 2010 to 2019, we analyze how the Small World characteristics and centrality of GRI contribute to academic performance using a network analysis and Feasible GLS regression. The GRI cooperative network has shown that the Small World network structure facilitates the academic performance. In addition, centrality indicating the degree of direct connection showed positive significance, but centrality indicating the degree of intermediary was not significant or negative. The results of this study explain that the higher the number of institutions that exchange and cooperate, the higher the academic performance, and the higher the performance of the institutions that serve as the center of cooperation. In addition, it was established that the stronger the cooperative network of GRIs have the characteristics of Small World, the more effective it is to create research results. This study applies centrality and Small World previously discussed as an efficient network structure to the GRI cooperation network and provide implications for establishing policies and strategies related to R&D cooperation among GRIs.

In coastal waters, phytoplankton,suspended particulate matter, and dissolved organic matter intricately and nonlinearly alter the reflectivity of seawater. Neural network technology, which has been rapidly advancing recently, offers the advantage of effectively representing complex nonlinear relationships. In previous studies, a three-stage neural network was constructed to extract the inherent optical properties of each component. However, this study proposes an algorithm that directly employs a deep neural network. The dataset used in this study consists of synthetic data provided by the International Ocean Color Coordination Group, with the input data comprising above-surface remote-sensing reflectance at nine different wavelengths. We derived inherent optical properties using this dataset based on a deep neural network. To evaluate performance, we compared it with a quasi-analytical algorithm and analyzed the impact of log transformation on the performance of the deep neural network algorithm in relation to data distribution. As a result, we found that the deep neural network algorithm accurately estimated the inherent optical properties except for the absorption coefficient of suspended particulate matter (R² greater than or equal to 0.9) and successfully separated the sum of the absorption coefficient of suspended particulate matter and dissolved organic matter into the absorption coefficient of suspended particulate matter and dissolved organic matter, respectively. We also observed that the algorithm, when directly applied without log transformation of the data, showed little difference in performance. To effectively apply the findings of this study to ocean color data processing, further research is needed to perform learning using field data and additional datasets from various marine regions, compare and analyze empirical and semi-analytical methods, and appropriately assess the strengths and weaknesses of each algorithm.

It is common description that modern society is In the era of limitless competition. In order to challenge the change of economy and its management at home and abroad, organization should be changed anew, and in this case, there accompanies conflict or trouble whether the subject of change wants it or not. Therefore, according to change, we should concern with settlement of small troubles as well as big ones, and by managing the conflict or trouble productively and originally, it should be utilized as new fatality and chance to develop something in organization. In the system organized by people, there exist various conflicts in accordance with the target and want of the system, therefore giving no freedom to each Individual member of the system, and this is an unavoidable tate in consideration of the modem society where the survival of mankind and human systems should be guaranteed. Therefore, it determines the coordinates of success of any of organizations to manage conflict or trouble well, and so, when decreasing or increasing conflicts so that the organization exerts its full influence, it is note worthy that conflict itself should be rationally and efficiently managed. In a view point of the theory of organization and its behavior, relating job satisfaction with the performance and validity of organization, the influence of individual conflict is so great on the rate of job transfer within an organization or nonattendance, even on the productivity of the organization. So, the manager to cope with conflict within an organization should devise following three plans to manage conflict for job satisfaction and conflict settlement. In conclusion, it is suggested that in order to manage conflict within an organization well, some plans to control conflict should be well utilized while giving more efforts to improving management of individual conflict, job satisfaction, validity of organization, productivity, etc and all the members of organization should remember that the Issue of conflict within an organization be recognized ad an opportunity of new development and a way to settle a trouble within an organization, and a direction of conflict management should be suggested so that new innovation ca be created.

The purpose of this study is to investigate the features of science classes of Science Core Schools (SCSs) perceived by students. 654 students from 14 SCSs were surveyed with two open-ended questions on the features of science classes. The students' responses were analyzed with NetMiner 4.5, in terms of the centrality (of betweenness and of degree) analysis and the community analysis. The results of the research are as follows: (1) the science classes of SCSs were perceived by students to be of the environment of free questioning, active participation and communication, caring teacher, more science experiments and advanced contents, and knowledge sharing; (2) science classes in SCSs were perceived to be different from those of ordinary high schools because SCSs provide more opportunities for science-related special courses (like project work, advanced science subjects), extra-curricular activities, inquiry and research activities, school supports, hard-working classroom environment, longer studying hours, R&E and club activities. The students' perceptions of SCS science classes appear to be in line with the characteristics of 'good' science lessons from previous studies. The SCS project itself and the features of SCS science classes would help us to see how we introduce educational innovations into actual schools.

The purpose of this study is to examine the appropriateness of Regulatory Impact Analysis(RIA) in terms of the technological regulation impact assessment in order to confirm whether the current RIA process reflects the important characteristics of technological regulation. This paper develops a logical framework for analysis of technological regulation and evaluates the appropriateness of the RIA statements submitted by the government departments. From the viewpoint of [technological feasibility of regulation], [synthesis of domestic technological norms], [synthesis of international technological norms], as a result of evaluating the contents of the actual RIA statement on the basis of objective facts, feasibility of alternative analysis, and expert judgment, only 23.4% of the RIA statements were judged "appropriate", and there were no particular differences among the government. As a result of reviewing the appropriateness of RIA statements according to regulatory attributes, the appropriateness of RIA statements on technological regulation with social regulatory and indirect regulatory attributes was rather high. In sum, the level of Korean RIA statements is insufficient to carry out the practical meaning of technological regulation impact assessment. That is, as each government department adopts technological regulation, the understanding of the technological properties of the regulation may not be complete. The RIA statement that does not adequately reflect the technological rationale, hinders the careful review of other regulatory alternatives by exaggerating the feasibility of the technology regulation, at the same time leads to the serious problems that impede the acquisition of competitiveness of companies and the public in the global competition system.

In the era of fierce global competition and short product life cycle, firms have been interested in the technology valuation to improve their competitiveness. As the technology valuation may become a key issue for countries and industries, the development of technology valuation method has become increasingly important. Thus, this study aims to suggest a novel method to assess technology value by applying conjoint analysis to bibilographic information of patent. For this purpose, we firstly identified nine patent indexes categorized in three attributes - technological superiority, marketability and legal rights. Then, we collected actual data on patent transactions including their patent attributes and market prices. Based on the data, we could obtain the patent index values. Finally, we applied conjoint analysis to the prices and patent index values as a basis for technology valuation. The suggested method is expected to be an effective tool for technology valuation by using real transaction data rather than relying heavily on experts assessment.

유기셀레늄급원을 달리하여 쇠고기 육색 안정성에 미치는 영향을 분석한 결과는 다음과 같다. Myoglobin의 함량은 대조구와 시험구에서 각각 6.39%, 14.18%로 대조구가 시험구에 비하여 낮은 결과를 보였으며, Oxy-Myoglobin의 함량은 반대로 대조구 89.07%, 시험구 83.47%로 시험구가 대조구에 비하여 낮은 결과를 보였다(p<0.05). 그러나 Met-myoglobin 함량은 대조구가 4.56%이였고 시험구가 2.35%로 대조구가 높은 결과를 보였다. 보다 정확한 결과를 평가하기 위해서는 시료를 Met화 시킨 후 측정해 볼 필요성이 대두되어 도축후 $4^{\circ}C$에서 14일 및 21일간 숙성한 시료를 $20^{\circ}C$에서 48시간 산화시킨 후 측정 육색소 화학적 조성을 비교한 결과, 육색소 화학적 조성을 비교한 결과로 Myoglobin 함량은 저장 14일차와 21일차에서 유의적인 차이를 보이지 않았으나, Oxy- myoglobin은 저장 14일차와 21일차 모두 유기셀레늄 강화 버섯 폐배지 급여구가 대조구와 무기셀레늄 급여구에 비하여 높은 결과를 보였다.

생활이 풍족해질수록 사람들은 음식이나 음료를 통하여 미각을 즐기는 경향이 강해지고 있다. 미각이 발달한 사람들은 다른 감각이 발달한 사람들보다 소비 욕구가 왕성하여 상품정보에 밝은 편이고 신제품에 대한 호기심도 많아 주요고객으로 환영받을 수 있는 가능성이 매우 높다. 이러한 점을 고려할 때 미각은 소비성향의 척도가 될 수 있으며, 이것이 상품개발에 중요한 지표가 될 가능성이 있다. 그러나 맛에 민감하다거나 둔감하다고 표현되는 개인의 미각물질에 대한 감도는 개인마다 일정치 않다. 이것은 미각물질에 따라 개인의 상대적인 역치의 고조나 미각 강도의 대소가 다르거나 감도가 다른 미각물질에 대한 수용구조에 개인차가 있기 때문이다. 이처럼 개인차가 있는 미각을 표준화된 방법으로 측정하는 것은 그리 쉬운 일이 아니다. 미각강도 측정을 위한 Time-Intensity curve는 1958년 음식물의 특성에 대해 관심을 가졌던 Nielson에 의해 개발되었는데 최근에 Takagi와 Asakura가 Time-Intensity curve분석과 기록을 위해 microcomputer를 이용한 방법을 개발하였다. 그들의 방범은 Time-Intensity curve를 모니터에 보여주고 data를 floppy discs에 기록하여 software로 분석하는 것이다. 본 연구는 이것을 좀더 편리하고 단순하게 만들기 위해 감각의 강도를 전기적 저항의 interface를 통하여 computer에 입력하는 대신에 mouse를 이용하여 입력하는 방법을 개발하였다. 새로이 개발된 Time-Intensity curve를 이용하여 커피성분 중 설탕과 프림의 농도에 변화를 주어 맛의 좋고 싫음의 미각강도를 측정하는 실험을 하였다. 그 결과 상품개발의 중요한 지표가 되는 미각의 강도를 측정할 수 있었고 이것은 향후 commercial한 상품의 개발에 유용한 지표가 될 것이라고 본다.시사한다. 본 연구에서는 한국 연구 조직에서 일하는 외국인 연구자들의 동기 및 성과에 영향을 미치는 많은 요인들을 확인할 수 있었다. 상관관계, 분산분석, 회귀분석 등을 통해 활용 성과에 미치는 영향 요인들을 도출하였다. 설문 분석을 통하여 동기 및 성과 사이에는 강한 상관관계가 존재하는 것을 확인할 수 있었으며 이는 전통적인 동기 이론들과 부합한다. 대부분의 변수가 동기 및 성과에 동시에 영향을 미치는 것으로 조사되었으며 그중에서도 조직 협력 문화, 외국인 연구자의 의사소통 및 협력성, 외국인 연구자의 연구 능력 관련 변수들 및 연구 프로젝트의 기술수명주기, 외국인 연구자의 기존 기술지식의 흡수 등이 가장 중요한 변수로 나타났다. 이는 우리가 주로 중국 및 러시아 과학자들을 활용하여 상업화하는 외국인 연구인력 활용 패턴과도 일치하는 결과이다. 즉 우호적인 조직문화를 가지고 있는 연구 조직에서, 이미 과학기술 지식을 많이 가지고 있고 연구 능력도 높은 외국인 과학기술자를, 한국에서 기술이 태동 또는 성장하고 있는 연구 분야에서 활용하는 것이 가장 성과가 좋다는 사실을 확인시켜 주고 있다. 국내에서 최초로 수행된 본 연구는 외국인 연구 인력의 활용 성과가 매우 높으며, 우리의 과학기술혁신시스템을 보완하는 유효한 수단으로써 외국인 연구 인력이 중요한 대안이 될 수 있음을 발견하였다. 외국인 연구 인력을 잘 활용하기 위하여 문제점 및 개선방안을 활용 환경, 연구 인력이 중요한 대안이 될 수 있음을 발견하였다. 외국인 연구 인력을 잘 활용하기 위하여 문제점 및 개선 방안을 활용 환경, 연구 인력관리. 인력 교류사업, 외국인 과학자 지원 창구 등으로 나누어서 정리하였다. 연구시설, 주거시설 등의 하드웨어적 환경에 대한 개선도 중요하지만 연구 인력의 관리 능력 제고, 인력 교류 사업의 개선, 정보 제공 등 소프트웨어적인 활용 능력을 제고하는데 정책적인 관심을 기

Investments in new technologies have grown significantly in size, and science and technology have a large and complex impact on society at large. With people's great interest in technology, the government has the duty to accurately assess the influence of new technologies on society to facilitate their acceptance in society. For this purpose, technology impact assessment should be performed to facilitate a social consensus. There has been research on the initial methods of technology assessment for 50 years. Following various academic studies and discussions based on numerous new technology response policies, coupled with the examination of trends and changes over time, academia and policymakers around the world have paid attention to the multilateral analysis of the impact of new technologies on future society. This study focuses on research changes such as the stage of forecasting factors that should consider the technology assessment of new technologies, despite differences between the development methods for the assessment between developed countries and South Korea. The analysis yielded three factors of technological understanding of awareness, professionalism, and gender characteristics, in addition to a previously identified factor. The three factors are then suggested as forecasting factors for new technology. The findings of this study provide both academic and policy evidence for technology assessment based on the country's Framework Act on Science and Technology.
