This paper shows linkage management for external services. There are many services for specific entities such as DBLP and OntoWorld. OntoFrame, as a Semantic Web-based research information service portal, aims at one-stop service in ways that it connects external services with hyperlinks. For managing the linkage, linkage rules are manually edited by human administrators and automatically verified and tested by linkage management system. It consists of linkage rule management, linkage rule verification, linkage test, and dynamic link generation. Linkage rule management creates and edits linkage rules to connect external services on the Web. After finished rule editing and verification step, linkage management invokes linkage test with entity list. Only valid links are visible to enable users to click on our system, and thus it increases user's reliability on the system.

This study analyzed the linkage relations of technological innovation between Daedeok Innopolis and other seven innovative clusters in industrial complexes which have played important roles as innovative centers in Korea. To begin with, we selected major technologies of Daedeok Innopolis for which the linkage with other clusters of innovative activities was analyzed quantitatively and graphically with association matrices, network analysis and dendrogram. Based on this network analysis, we analyzed the technological linkage among clusters and found the direction and strength of technological cooperation of the Daedeok Innopolis with other innovative clusters by technology field. This study analyzed the technological network between the Daedeok Innopolis and other clusters on 6 technology fields in which Daedeok has innovative capabilities. In the analysis was measured the centrality of Daedeok compared with that of other clusters in areas where Daedeok is relatively active in innovative activities. As a result, Daedeok showed the highest centrality with the active innovative activities. Except Daedeok, Banwol-Sihwa cluster showed the highest centrality in all of the 6 technology fields. Putting all the centrality of each innovative cluster and the linkage relations of Daedeok Innopolis together, it need to consider the following policy directions to strengthen the innovative linkage with other clusters. In Daedeok's main technology areas, it needs to increase the regional linkage with the clusters with relatively high centrality and relatively low linkage with Daedeok. For Changwon, Wonju and Gunsan with which Daedeok has the relatively low innovative linkage, it need to examine a new policy to improve the linkage with technologies related with the industry other clusters are nurturing. When Daedeok formulates a plan to cooperate with other clusters, it does not only have to consider the linkage relations of technological innovation analyzed in this study and but also has to examine the cooperative strategies from the comprehensive point of view considering every aspect of their strategic industries, supportive policies, industrial base and competitiveness. This study analyzed the linkage relations between regions based on the network analysis of patents only by co-invention. Consequently, it did not examine the factors inducing the co-invention, which is a limitation of the study and is to be investigated in the future. Also, the exploratory analysis on determinants of linkage intensity and the strategies to get synergy effects through solidified linkage will be the issues of further study.

본 논문에서는 클러스터 간의 중복을 허용한 계층적 클러스터링(hierarchical clustering) 기법에 적합한 클러스터 간 유사도 평가방법(linkage metric)을 제안하였다. 클러스터 간 유사도 평가방법은 계층적 클러스터링에서 클러스터를 통합하거나 분해하는데 쓰이며 사용된 방법에 따라 클러스터링의 결과가 다르게 형성된다. 기존의 클러스터 간 유사도 평가방법인 single linkage, complete linkage, average linkage 중 single linkage와 complete linkage는 클러스터 간 중복이 허용된 환경에서 정확도가 낮은 문제점이 있고, average linkage는 정확도가 두 방법에 비해 높지만 계산 시간 소요가 크다는 단점이 있다. 따라서 본 논문에서는 기존의 average linkage를 개선하여 중복된 데이터에 의한 필요 계산량을 크게 줄임으로써 시간적 성능이 우수한 클러스터 간 유사도 평가방법을 제안하였다. 또한, 제안된 방법을 기존 방법들과 비교 실험하여 중복을 허용하는 계층적 클러스터링 환경에서 정확도는 비슷하거나 더 높고, average linkage에 비해 계산량이 감소됨을 확인하였다.

Localization of extension services in 1997 has weakened the linkage and cooperation between the central and district extension agencies(Provincial Agricultural Research & Extension Services and City & County Technology Centers). Since agriculture needs a national or regional dimension approach in many senses, it is important for agricultural prosperity to maintain and even further strengthen the practice of cooperation between different levels of governments and extension agencies.The objective of this study was to suggest policy measures to strengthen the linkage and cooperation between agricultural extension agencies. Existing works were reviewed to see a general picture of problems associated with he localization of extension services. In order to gain insight into policy measures, questionnaire surveys to extension staffs in districts(8 of 9 Provincial Agricultural Research & Extension Services and 160 of City & County Technology Centers) were conducted. Survey respondents were mainly asked about policy measures which would contribute to strengthen the linkage and cooperation between extension service agencies.Three policy measures derived from the study are: to expand the professional and technological education at the central level; to establish the central－local partnership; and to strengthen the linkage and cooperation between city & county agricultural technology centers.

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.

As the climate crisis intensifies, the need to improve the climate resilience of developing countries is ever increasing. Hence, the international community is seeking ways to effectively conduct climate technology transfer by linking the projects with financial mechanisms. However, commercialization of climate technology in developing countries is no easy feat as comprehensive knowledge on the target country is a prerequisite for seeking a suitable technology-financial linkage measure. Hence, in-depth discussions on effective climate technology and financial linkage measures have become an important global agenda, and South Korea, as a country with long experience in climate technology transfer, and a strong ecosystem for public climate technology, should step forward to take up a leading role. Against this backdrop, this paper proposes strategies and implementation measures for linking funds from the Multilateral Development Banks (MDB) with Korea's Public Climate Technology (PCT) by examining several key areas of R&D, international cooperation, and technology commercialization.

Since 4-bar linkage widely used in various industrial fields has a fixed link length, it is inconvenient to add an independent link structure or control device to change the movement of output link. Therefore, this paper proposes a new concept of variable 4-bar linkage mechanism to selectively adjust the movement of the output link to fit desired situations, and applied to the commercial table fans, which is a representative product using a 4-bar linkage system. The optimal rotation angle steps for efficiency are determined experimentally and the appropriate lengths of linkage to fit each step are calculated analytically. Changes in the linkage length are implemented by the rotational motion using a grooved cylindrical cam and the feasibility of the proposed variable linkage mechanism is verified through fabrication and measurement. The presented variable link mechanism is expected to improve the efficiency of industrial robots and fuel valve systems.

Urbanization has led to extreme changes in land use on urban watersheds. Most cities are becoming residential, commercial and industrial areas, making infiltration and storage of rainfall less favorable. The demand for LID (Low Impact Development) technology is increasing in order to mitigate this water cycle distortion and return to existing hydrological conditions. The LID technique is effective in reducing runoff by permeating the urban impervious area. However, considering the limit of the installation area and the financial requirement of the installation, there is not much research on the linkage of each LID component technology for optimum efficiency according to the appropriate scale. In this study, the effects of the LID facilities applied to the target site were simulated using the SWMM model, suggesting the optimal linkage method considering interconnectivity, and applying the effects as an existing installation of individual facilities. The water balance at the time of application of the LID technology, short-term and long-term rainfall event were compared. Also, the individual application and the linkage application were compared with each other. If each component technology has sufficient processing size, then linkage application is more effective than individual application.

In this study, an advanced knee joint for active prosthesis leg driven by a linear actuator is suggested. The structure of knee joints of existing active prosthesis legs consists of three links. This kind of linkage requires large torque to drive the active prosthesis legs. Thus a new linkage structure is suggested to solve such problem in this paper. Motion characteristics of the suggested linkage are examined in the simulation. The motion simulation results show that the proposed linkage is able to imitate human gait cycles with the half of linear actuator speed in existing linkages.

Basic research have contributed to technological growth or economic growth in U.S. Specially recent studies say that universities also contribute to economic development through scientific activities like science research, education, technology transfers. But we can not assure whether scientific knowledge was connected to real technology or economic performance, and it is difficult to figure out the effect of scientific output. "What is the exact performance of scientific knowledge?" It is still obscure. In this context, this paper analyzes characteristics of the linkage of science and technology. Data are U.S. R&D expenditure, scientific articles, citation of articles in U.S. patents by fields and sectors. As a result, university sector has the most weight of the linkage of science and technology. But, in relative connection rate analysis, industrial sector's is stronger than any other sectors. In the field analysis, linkage of science and technology is very strong in Chemistry, Physics, Biological sciences fields. And recently the linkage was increased in the fields of Computer science, Agricultural science, Engineering. Finally, this paper supports funding policy or estimation policy of government to product of scientific knowledge. University sector is still important because it has the most weight of the linkage. Scientific knowledge of industrial sector is also important. The connection rate of industrial science is the strongest in all sectors. And this research classify the R&D type by science fields. Considering the differences of science fields is needed to product science knowledge effectively.
