부모세대 낙농인들은 아무린 정보 없이 낙농업을 시작했기에 다방면의 시행착오를 겪으며 쌓아 온 소중한 '경험'을 가지고 있고, 후계낙농인들은 낙농과 축산에 대한 이론 교육은 물론 수많은 정보 속에서 알아낸 '지식'이 있다. 일반적으로 경험과 지식이 한데 모이면 큰 효과를 내기 마련이지만, 세대가 다르다는 이유로 갈등을 겪다 보면 시너지 효과를 제대로 얻을 수 없다. 그러나 경기 화성지역에는 소통을 통해 세대 간의 벽을 허문 모임이 있다. 바로 박홍섭 전(前)지회장을 축으로 지역 후계낙농인들이 모여 꾸려나가고 있는 '젖소개량 스터디그룹'이다. 목장에 필요한 경영노하우를 연구 토론하는 것은 물론 경험과 지식을 함께 나누고 있는 박홍섭 전(前)서울우유연합지회장과 후계낙농인들을 만나봤다.

This paper proposes a potential-based reinforcement learning, called "RLs-CBDT", which combines multiple RL agents and case-base decision theory designed for decision making in uncertain environment as an expert knowledge in RL. We empirically show that RLs-CBDT converges to an optimal policy faster than pre-existing RL algorithms through a Tetris experiment.

객체와 객체, 객체와 환경(공간 객체) 사이의 상호작용을 Field 라는 개념을 도입하여 개념적으로 장 이론이라는 방법론으로 객체들간의 상호작용을 해석하였다. 구체적으로 환경은 공간에 대한 수학적 개념으로 정의하고 객체와 환경사이의 상호작용은 해석하였다. 구체적으로 환경은 공간에 대한 수학적 개념으로 정의하고 객체와 환경사이의 상호작용은 일련의 상호 의존적 사실들로 표현하였다. 따라서 공간에 대한 수학적 개념과 힘의 역동 개념을 동원해서 객체와 환경이 주어진 상황에서 나타나는 구체적인 행동을 기술한다. Vector, Algebra, Topology 등과 같은 물리학적 및 수학적 개념을 도입하여 객체 상호작용을 해석하기 위한 과학적 이론 시스템 개발에 활용할 가능성을 제시하였다.

This study attempts to explore factors that influence the perception of importance of information security. Three possible exogenous variables including perceived certainty of punishment, perceived response cost, and acquiescense are suggested that are based on the protectiom motivation theory. As a result, we found followings. First, The perceived punishment certainty has a significant effect on the perceived importance of information security. Also, it influences a negative effect on acquiescence. Second, the response cost has a negative effect on the perceived importance of information security. In addition, the response cost positively effects on acquiescence. Finally, acquiescence negatively influences on the perceived importance of information security. The results show that, in order to increase the perceived importance of information security among employees, it is necessary to make them aware that a security violation can result in certain punishment. At the same time, organizations should also attempt to remove major obstacles accompanying security behaviors of employees. Finally, organizations encourage open communication relating to information security among employees.

In this paper, we introduce a new solution for the load balancing problem, an important issue in parallel processing. Our heuristic load balancing technique called MGA effectively combines the benefit of both mean-field annealing (MFA) and genetic algorithms (GA). We compare the proposed MGA algorithm with other mapping algorithms (MFA, GA-l, and GA-2). A multiprocessor mapping algorithm simulation has been developed to measure performance improvement ratio of these algorithms. Our experimental results show that our new technique, the composition of heuristic mapping methods improves performance over the conventional ones, in terms of solution quality with a longer run time.

This paper describes MFT(Mean Field Theory) neural network with continuous with continuous variables is applied to quantification analysis problem. A quantification analysis problem, one of the important problems in statistics, is NP complete and arises in the optimal location of objects in the design space according to the given similarities only. This paper presents a MFT neural network with continuous variables for the quantification problem. Starting with reformulation of the quantification problem to the penalty problem, this paper propose a "one-variable stochastic simulated annealing(one-variable SSA)" based on the mean field approximation. This makes it possible to evaluate of the spin average faster than real value calculating in the MFT neural network with continuous variables. Consequently, some experimental results show the feasibility of this approach to overcome the difficulties to evaluate the spin average value expressed by the integral in such models.ch models.

Studies on western art in Korea has been caught in a dilemma that they could deal with only those things which had been arranged according to their 'historical generalization' in their contexts because of the bounds of time and space. It is not trivial that such conditions affect art studies in Korea. Access to the original texts and to their contexts of production is so restricted that the studies on them are prone to he superficial. And it is not independent on the politics of Korean art scene. Such factors are on the background of Korean art's excessive 'assimilation or accordance' with western art. The domestic studies on western art history and art theory have failed to notice the differences in context and Korean art has simply mediated or reproduced the restricted information by those studies. Also the studies on western art in Korea have been made use of as a justifying method of one's own academic domains. In such situations we should lead the studies on western art history and western art theory to a more reflective direction and confirm that the studies should not have any privileges of the realities. And we should try to reform a scholarship which participates in our life and existence. The field of domestic studies on western art history and western art theory should free itself from the invention of objectivity or the neutrality of mechanical reading and turn its eyes to the realities of life where events happens. Constantly suggesting which way Korean art and world art should go has to be the field's new coordinates.

This paper addresses a method of enabling objects in an image to have apparent 3D motion. Many researchers have solved this issue by reconstructing 3D model from several images using image-based modeling techniques, or building a cube-modeled scene from camera calibration using vanishing points. This paper, however, presents the possibility of image-based motion without exact 3D information of scene geometry and camera calibration. The proposed system considers the image plane as a projective plane with respect to a view point and models a 2D frame of a projected 3D object using only lines and points. And a modeled frame refers to its vanishing points as local coordinates when it is transformed.

Knowledge ecosystem means a dynamic knowledge circulation, including knowledge creation, exchange and sharing and utilization. It is also the field of knowledge practice, which creates interactions in knowledge exchange between people and groups. The key premises of knowledge ecosystem, based on the nature of general ecosystems, can be characterized as follows: first, it primarily focuses on social networks between people and organizations participating in the process of knowledge circulation; secondly, knowledge ecosystem thrives on diversity of knowledge; and thirdly, it is significant for selection of valuable knowledge and adoption of appropriate knowledge. This review attempts to make a systematic examination of a wide range of existing studies on knowledge ecosystem. In so doing, it is expected to provide a basis for further inquiry into more critical and complicated issues. Although the scarcity of existing research-at least those in Korea-may limit the implications of findings, this review offers a set of suggestions for future research.
