혁신클러스터 이론에서는 산학연 협력 등을 통해 암묵적 지식과 노하우 접근이 수월할수록 클러스터의 성장이 촉진된다. 산학협력이란 산학연간의 공동연구를 지원하는 혁신네트워크 정책이라고 할 수 있다. 이러한 측면에서 최근의 정부 정책의 흐름은 산학연협력 생태계가 자발적으로 조성되도록 대학 및 연구기관의 지원 전담조직을 활성화 하고 있는 추세이다. 중소기업청은 2013년도에 우수한 연구기반을 갖춘 대학 또는 연구기관 내에 중소기업의 연구 기능을 집적화하여 산학연협력 연구개발 및 사업화를 지원하기 위한 '연구마을 지원사업'을 첫 시행하였다. 이러한 권역별 특성을 반영한 사업의 생태계가 잘 조성되기 위해서는 지역의 특화산업을 반영한 산학협력기술개발이 추진되어야 할 것이다. 특화발굴 전략이 잘 반영된 연구마을의 경우, 유사 기술분야 기업들의 집적화로 자연스럽게 클러스터가 조성되어 연구의 시너지를 창출 할 수 있을 것이다. 이에 본 사업에 참여한 충청권의 연구마을 특화분야 발굴사례를 통해 지역 특화사업 연계 전략을 조사 정리하여 향후 연구마을뿐만 아니라 지역특화 전략에 기반한 산학협력을 추구하는 기관에 발굴전략을 제시하고 정부의 클러스터정책이 활성화 될 수 있도록 정책적 제언을 제시해보고자 한다.

Recently, robotic automation in clinical laboratory becomes of keen interest as a fusion of bio and robotic technology. In this paper, we present a new robotic platform for clinical tests suitable for small or medium sized laboratories using mobile robots. The mobile robot called Mobile Agent is designed as transfer system of blood samples, reagents, microplates, and any instruments. Also, the developed mobile agent can perform diverse tests simultaneously based on its cooperative and distributed ability. The driving circuits for the mobile agent are embedded in the robot, and each mobile agent communicates with other agents by using Bluetooth communication. The RFID system is used to recognize patient information. Also, the magnetic hall sensor is embedded to remove and compensate the cumulated error of locomotion at the bottom of mobile agent. The proposed mobile agent can be easily used for various applications because it is designed to be compatible with general software development tools. The Mobile agents are manufactured, and feasibility of the robot and localization of the agents using magnetic hall sensor are validated by preliminary experiments.

일반적으로 무선 센서 네트워크는 다수의 노드들을 무작위로 배포하여 데이터를 수집하기 때문에 각 노드로부터 수집되는 데이터뿐만 아니라 계측하는 노드의 위치 또한 매우 중요하다. 무선 센서 네트워크를 구성하는 노드들은 저비용, 저성능의 장치들로 구성되어 있어 위치 측정을 위한 전용 장치를 노드에 추가하는 것은 매우 어렵다. 그러므로 무선센서 네트워크에서 저비용으로 노드의 위치를 정확히 측정하는 것은 매우 중요한 기술이다. 본 연구에서는 위치 측정의 정확성을 높이고, 다수의 센서에 대해서도 정해진 시간 내에 위치를 결정할 수 있는 확장 가능한 상호 협력 위치 측정 시스템을 제안한다. 그리고 시뮬레이션을 통하여 성능, 정확성, 확장성이 우수함을 보였다.

Korean agriculture and rural sector has undergone a wide range of reform after the Uruguay Round. Major policy measure is to put finances of huge budget from tax payers since 1994 in preparation of the Rural Development Strategy and Reform Program. Both in the total amount and individual size of the subsidy and loan for eligible farmers and farmers group are large and drastically enormous than any other programs in the past. The strategy adopted was a bottom-up approach, Particularly in selecting the project with local autonomy. However, it has been still criticized as the form of centralized control of budget and decsion. In terms of the program effectiveness too, it is doubtful to judge that Korean agriculture is in a road to getting the international competetiveness as targeted. Since the local autonomy was started in 1995, the political structure has been settling in a way to be more locally institutionalized. Rural development policy, as the key point of economic and industrial dimension of local autonomy, should be initiated and practiced in real term by the local government. This paper, in this concern, in reviewing the past rural development prolicy and programs, discussed the necessary issues relevant to legal bases of land uses in Korea. Further, the direction of increasing local automous power of local government was discussed in the senses of budgetary control and decision. The power and budget should be allocated more to the rural development plans of local government in order to fulfilize integrated rural spatial development in this new era of globalization.

본 연구는 자기 홀 센서의 특성으로 인해 실내 환경에서만 이용이 되었던 자기/자기-자이로유도 타입의 무인운반차를 실외 환경에서도 적용이 가능하도록 실외 주행용 자기 위치측정 장치를 설계 및 제작하는 것이다. 현재 이용되고 있는 자기 위치측정 장치는 측정 높이가 30mm로 바닥 환경이 고르고 평평한 실내 환경에 적합한 구조이다. 하지만 바닥 환경이 울퉁불퉁하거나 불균형적인 실외환경에 이용되는 무인운반차에는 부적합하다. 그 이유는 무인운반차 서스펜션이 부착되게 되고, 이 때 자기 위치측정 장치의 부착높이가 30mm 이하로 무인운반차에 가해진 충격으로 인해 장치와 바닥과의 충돌이 발생하게 되면 장치가 파손되기 때문이다. 따라서 실외 자기유도 무인운반차에 적용하기 위해서는 100mm 이상의 측정 높이를 가지는 자기 위치측정 장치가 필요하다. 현재 자기위치측정 장치의 성능 향상 및 개발에 관련된 다양한 연구들이 진행되었지만, 다양한 자기 홀 센서를 분석하여 본 논문에서는 자기위치측정 장치를 설계 및 제작하였고, 자기 홀 센서의 특성 정보를 이용한 특성 함수를 이용해 자성체의 위치를 검출하였다. 실험을 위하여 알루미늄을 이용한 실험 장비를 제작하였으며, 제안된 자기 위치측정 장치를 이용하여 실험한 결과 위치측정 정밀도 오차는 10mm 이하이고, 측정 높이는 평균 150mm 로 실외 자기유도 무인운반차에 적합한 것을 확인하였다.

Objectives : This study was designed to find clinical factors that could be differentiated by the lateralization of lesion and also find clinical factors to predict the lateralization of lesion. Methods : The subjects were 65 cooperative inpatients and outpatients with non-traumatic subcortical cerebrovascular disease without neurologic and psychiatric history from January 1995 to September 1995 ; 48 patients in Kyung Hee University, Oriental Medicine Hospital, 35 patients in Anam Hospital, Korea University were examined as subjects, but authors excluded 20 patients whose data were incomplete or who had uncertain lesions on brain CT or MRI. The 65 patients were divided into three groups-group with left hemispheric lesion, group with right hemispheric lesion, group with both hemispheric lesion-according to the finding of brain imaging study. Their cognitive functions were evaluated by the Benton Neuropsychological Assessment(BNA), their subjective neurobehavioral symptoms by Symptom Check List-90-R(SCL-90-R), their objective neurobehavioral symptoms by Neurobehavioral Rating Scale, and their daily living functions by Geriatric Evaluation by Relative's Rating Instrument(GERRl) and Instrumental Activities of Daily Living Scale(IADLs). Results : The results were as follows : 1) The results of cognitive function test indicated that the group with right hemispheric lesion showed low functions in Tactile Form Perception(left), the group with left hemispheric lesion showed low functions in Finger localization(right), the group with right hemispheric lesion showed low functions in Finger Localization(left). 2) Though, there were little significant differences in subjective neurobehavioral symptoms, the group with right hemispheric lesion showed higher scores in all symptoms except hostility. 3) Though, there were little significant differences in objective neurobehavioral symptoms, the group with both hemispheric lesion showed higher scores in cognition, guilty/disinhibition, the group with left hemispheric lesion showed higher scores in lability of mood, the group with right hemispheric lesion showed highest scores in psychotism, neurotism, agitation-hostility and decreased motivation/emotional withdrawal. 4) There were little significant differences among three groups in Daily Living Functions, but the group with right hemispheric lesion showed the lowest functions in Instrumental Activities of Daily Living. 5) As a result of discriminant analysis on each factor's contribution to the prediction of lesion, Finger Localization(left), Phoneme Discrimination and Tactile Form Perception(right) showed that they had the potentiality to predict lesion. Conclusion : The results suggest that there are little significant differences among the groups of three non-traumatic subcortical cerebrovascular disease in cognitive functions, but the group with right hemispheric lesion showed more serious and various changes in subjective and objective neurobehavioral symptoms, and showed low functions in Instrumental Activities of Daily Living. This results suggest the possibility that the decline of the daily living function in the group with right hemispheric lesion were due to various symptoms, not due to cognitive dysfunction. The confirmation of the possibility should be worked out through the follow-up study of some groups containing cortical lesion. Apart from these findings, Finger Localization, Tactile Form Perception(right) and Phoneme Discrimination suggest that they can be used as clinically valuable cognitive parameters that predict the lateralization of lesion in non-traumatic cerebrovascular disease.

The purpose of this study was to classify types of family visitors' behaviors more concretely, which could be useful in planning of exhibition spaces in a science museum, with given priority to their behaviors according to interaction between them, and to understand characteristics of the behaviors. With this view, the scope of this study was restricted to subjects, who were family visitors of Gwacheon National Science Museum, consisting of parents and their one elementary school child per family unit. For understanding their behaviors, itinerary tracking and observation method of behavior were conducted. Moreover, for understanding substantial types and characteristics of family visitors' behaviors, multivariate analysis was applied. Accordingly, the results of the study are as follows. First, as a result of factor analysis, two main factors were derived. In other words, they were 'Durability of viewing' as the first and 'Interactivity between family members' as the second, which were shown valid in classification of the types of their behaviors. Second, according to the factors derived, the types of their behaviors were classified into in-depth cooperative viewing, selective independent viewing, interest concentration child-led viewing and consideration parent-led viewing. They were shown valid in topological localization and classification, as a result of analysis of the main factors. Third, in view of common characteristics of the types, it is judged that active orientation prior to regular viewing could encourage visitors coming to the museum for the first time to feel more friendly to unfamiliar exhibition environments, during the initial seek time, and to reduce visual supersaturation. Fourth, it is judged that distributed arrangement of exhibits, which result in continuous standby, could avoid confused visitor circulation by the estimated time required for viewing.

Purpose - After the transition, the development of defense industry in Eastern Europe has been regressed. Recently, they have internationally recognized that new products have been exported and contributed to the Innovation-Based Manufacturing of national economy such as unmanned reconnaissance aircraft, water purification technology, and mobile chemical laboratory, etc. The military forces in Eastern Europe are re-armed by the localization of self-produced munitions in their own defense industry, and then emphasize fostering their own defense industry. Thus, if they make a collaboration with other nations as a industrial cluster, it will gain a competitive edge on the defense industry. Research design, data, and methodology - The study was designed with the data of each national defense department. The research of the subject was reviewed before and after the transition. Thousands of workers have worked in defense industries before the transition, however, the defense industry and experts left after the transition. The Hungarian defense spending on GDP also dropped sharply from 1.72% in 2000 to 0.85% in 2013. But, due to the crisis in Ukraine and the crisis of Syrian refugees, the Viségrad Group (V4) member countries have also increased their interest in a defense and industries as well as the confidence in the EU and NATO. Results - On the whole, the joint of military training and purchase of defense materials were found in order to form the EU cooperative combat troops in CEE. There are the implementation of a joint manual plan for strengthening V4 security policy and the joint military exercises for V4 every year, and the others are electronic warfare and innovation of V4 national forces. Through such a performance analysis methodology, we found that the defense industry is developed through the national cluster cooperation among CEEs and spreading global distribution. Conclusions - Eastern Europe and Balkan countries have been looking forward to cooperating with the non-EU countries such as Korea and other defense industries. There are a lot of potential development into a new civilian cooperation defense industry for global-distribution. Thus, Korea should develop electronic commercial applications, not just as a weapon exporting region.
