For national industrial development in the Fourth Industrial Revolution, it is necessary to provide researchers with appropriate job information. This can be achieved by interconnecting the National Science and Technology Standard Classification System used for management of research activity with the Korean Employment Classification of Occupations used for job information management. In the present study, an automatic linkage model of classification systems is introduced based on a pre-trained language model for interconnecting science and technology information with job information. We propose for the first time an automatic model for linkage of classification systems. Our model effectively maps similar classes between the National Science & Technology Standard Classification System and Korean Employment Classification of Occupations. Moreover, the model increases interconnection performance by considering hierarchical features of classification systems. Experimental results show that precision and recall of the proposed model are about 0.82 and 0.84, respectively.

미국에서 기초연구는 기술발전 또는 경제성장에 크게 기여한 것으로 여겨진다. 특히 기초과학의 상당 부분을 담당하는 대학은 과학지식 연구, 교육, 기술이전 등의 활동을 통해 경제성장에 실질적으로 기여하고 있는 것으로 평가받고 있다. 그러나 과학이 기술적 성과에 어떤 영향을 얼마나 끼치는가는 아직 명확하지 않으며, 여러 학자들은 과학과 기술의 상호작용은 생각보다 매우 복잡하다고 말한다. 이 연구는 이러한 맥락에서 과학지식과 기술의 상호작용(또는 과학기술연계) 특성을 분석하였다. 분석은 미국을 대상으로 하였다. 미국의 R&D지출 규모, 과학논문수, 특허에 인용된 과학논문 등을 활용하였다. 분석결과 미국특허는 대학의 과학논문을 가장 많이 인용하였다. 그러나 전체 과학논문수를 고려한 상대적 인용 강도는 산업부문이 더 높았다. 즉, 과학과 기술의 연계는 대학에서 가장 많이 이루어지지만 상대적인 크기를 고려하면 산업부문의 과학지식이 더 활발하게 기술로 이어지고 있다고 볼 수 있다. 한편 과학분야별 분석에서는 화학, 물리, 생물학 분야에서 과학기술연계가 가장 활발하게 이루어지고 있었다. 특히 컴퓨터과학, 농경학, 공학 분야는 최근 연계강도가 크게 증가하였다. 결과적으로 본 연구는 과학지식에 대한 정부지원정책 또는 연구개발평가 등에 도움을 줄 것으로 기대된다. 대학은 가장 많은 과학기술연계가 이루어지는 공간이며, 이 점에서 대학 기초과학에 대한 정부지원은 여전히 중요하다. 산업부문 과학지식은 다른 연구주체보다 상대적으로 기술연계강도가 높았으며, 이는 산업부문의 과학지식생산 또한 장려할 필요가 있다는 것을 의미한다. 과학분야별로는 각 과학분야의 R&D유형을 4가지로 분류하여 연구결과의 정책적 활용도를 높이고자 하였다.

Cereal $\beta$-glucans, linked essentially by mixed $\beta$-(1,4/1,3) glycosidic bonds, were extracted, purified, and structurally identified. Previously chemical structure of barley $\beta$-glucans was characterized from 3 varieties of 'Gang', 'Ohl', and 'Gwangan', and the (1,4)/(1,3) linkage ratio of the $\beta$-glucans was identical. In this study, $\beta$-glucans from 1 barley ('Chal') and 3 oat ('Ohl', 'Samhan', and 'Donghan') varieties were structurally scrutinized, and the linkage pattern of total 7 cereal $\beta$-glucans was compared. The amount of 2 major 3-O-$\beta$-cellobiosyl-D-glucose (DP3) and 3-O-$\beta$-cellotriosyl-D-glucose (DP4) from barley and oat accounted for only 66.6-73.3 and 68.12-81.89% of water-extractable $\beta$-glucan fractions, and the (1,4)/(1,3) linkage ratios of both barley and oat $\beta$-glucans were within very narrow range of 2.27-2.31 and 2.38-2.39, respectively, among the cultivars tested. Structural difference in the cereal $\beta$-glucans was evident when DP3:DP4 ratio in the $\beta$-glucan structure was compared. As a result, this ratio was significantly greater for barley $\beta$-glucan (2.26-2.74) than for oat (1.54-1.66). Chal-B had the greatest DP3 to DP4 ratio among the samples, which in turn reflected the least amount of (1,4)-linkages.

In this paper, a flux linkage model based on four magnetization curves fitting is proposed for three-phase 12/8 switched reluctance motor (SRM), with the analysis of the basic principle of flux detection method and function analysis method. In the model, the single value function mapping relationship between position angle and flux is established, which can achieve a direct estimation of rotor position. The realization scheme of SRM indirect position detection system is presented. It is proved by simulation and experiment that the proposed scheme is suitable for rotor position detection of SRM, and has high accuracy of position estimation.

Recently, the interdisciplinary linkage between engineering and social science has received an increasing attention as an emerging education discipline. Due to intrinsic complexity of innovation process and heterogeneity of disciplinary nature, however there exists little, if not no, effort to draw a common framework in terms of educational scope and contents of the new subject. This paper presents a number of criteria and guidelines for building up new educational framework by integrating engineering subject and social science subject. Specifically, three neo-disciplines, technology policy, technology management, and economics of technology are considered since it is postulated that the forementioned disciplines have established academic identity and fundamental structure By nature, this paper is an exploratory and seminal one. It is not the purpose of this paper to provide a concrete table of contents of educational material. Instead, it merely brings up a discussion topic for the wide audience of academic arena, leaving the gradual consensus and convergence as future task.

In the knowledge based economy, it's important to know the place where the proper knowledge locates as well as to produce the creative knowledge. This paper intends to clear up the linkage structure between research fields and its application areas. 2,135 proposals submitted to Korea Science and Engineering Foundation were analyzed to investigate the relationship between research fields and application areas. The results are as follows; first, 51.8% of the basic research is devoted to the advancement of knowledge, second, 40.8％ of that is applicable to the industry, third, 5.8% and 1.2％ of that contributes to environment and social welfare.

Milk production traits are important economic traits for dairy cattle. The aim of the present study was to refine the position of previously detected quantitative trait loci (QTL) on bovine chromosome 6 affecting milk production traits in Chinese Holstein dairy cattle. A daughter design with 918 daughters from 8 elite sire families and 14 markers spanning the previously identified QTL region were used in the analysis. We employed a combined linkage and linkage disequilibrium analysis (LDLA) approach with two options for calculating the IBD probabilities, one was based on haplotypes of all 14 markers (named Method 1) and the other based on haplotypes with sliding windows of 5 markers (named Method 2). For milk fat yield, the two methods revealed a highly significant QTL located within a 6.5 cM interval (Method 1) and a 4.0 cM interval (Method 2), respectively. For milk protein yield, a highly significant QTL was detected within a 3.0 cM interval (Method 1) or a 2.5 cM interval (Method 2). These results confirmed the findings of our previous study and other studies, and greatly narrowed down the QTL positions.

This paper is an exploratory study to analyze the flow of knowledge in science and technology in order to predict technology innovation. Here, we need to look into the characteristics of how knowledge is created in science, technology and industry to start with. Based on the characteristics we find, we have to understand the relationships between science, technology and industry, and construct a model to link them to each other for future empirical studies. In this study, we take a general view of the existing study results and theoretical models on the characteristics and linkage of scientific and technological knowledge. Moreover, we examine the preliminary framework to link science to technology to industry for further study on the knowledge flow of science and technology. Finally, we present the direction for future study by using the examined models and framework.

A torque trajectory control of the IPM synchronous motor using an adaptive input-output linearization technique is proposed. The input-output linearization is performed using the estimated torque output with the knowledge of machine parameters. The linearized model gives the output torque error under the variation of the flux linkage. To give a good torque tracking in the presence of the flux linkage variation, the flux linkage will be estimated where the adaptation law h derived by the Popov's hyperstability theory and the positivity concept. This estimated value is also used for the generation of the d-axis current command for the maximum torque control. Thus, a good torque tracking and the exact maximum torque-per-current operation will be obtained.
