Reinforcement learning if a kind of machine learning. It aims to adapt an agent to a given environment with a clue to a reward and a penalty. Q-learning [8] that is a representative reinforcement learning system treats a reward and a penalty at the same time. There is a problem how to decide an appropriate reward and penalty values. We know the Penalty Avoiding Rational Policy Making algorithm (PARP) [4] and the Penalty Avoiding Profit Sharing (PAPS) [2] as reinforcement learning systems to treat a reward and a penalty independently. though PAPS is a descendant algorithm of PARP, both PARP and PAPS tend to learn a local optimal policy. To overcome it, ion this paper, we propose the Multi Best method (MB) that is PAPS with the multi-start method[5]. MB selects the best policy in several policies that are learned by PAPS agents. By applying PS, PAPS and MB to a soccer game environment based on the SoccerBots[9], we show that MB is the best solution for the soccer game environment.

현재 목표기기(target node)의 위치를 측정하는 기술 중에 가장 정확도가 높다고 평가되는 방법은 ToA(Time of Arrival) 거리 측정(Ranging) 기술과 TDoA(Time Difference of Arrival) 거리 측정 기술을 이용한 위치 측정 방법이다. ToA와 TDoA는 시간을 기반으로 하는 거리 측정 기술이기 때문에 여러 개의 참조기기(Reference node)와 목표기기 사이의 시간 동기화와 오프셋이 중요시 된다. 참조기기와 목표기기 사이의 시간 동기화가 정확하게 이루어지지 않거나 참조기기 간 시간 오프셋이 발생할 경우 정확한 시점에서 신호를 검출할 수 없게 되어 거리오차가 발생하게 되고, 이러한 거리오차를 일반적인 위치 측정 알고리즘에 적용하게 되면 목표 기기의 정확한 위치를 측정할 수 없다. 따라서 본 논문에서는 참조기기와 목표기기 사이에 시간 동기화가 맞지 않을 경우와 참조기기와 참조기기 사이의 시간 오프셋이 발생할 경우에 위치 측정의 오차를 줄이는 ToA와 TDoA의 Hybrid 방식을 제안한다. 각각의 펄스가 직교성을 갖는 특징을 지닌 MHP(Modified Hermite Polynomial) 펄스를 이용하여 참조기기들이 각기 다른 MHP 펄스를 송수신하도록 하고 이를 통해 한 번의 MHP 펄스 송수신만으로 TDoA와 ToA 두 가지 방법을 모두 이용하여 각각의 거리를 측정하고 위치 계산을 할 수 있도록 한다. Hybrid 방식은 TDoA와 ToA 방법을 이용한 거리 측정을 반복적인 계산을 통해 실제 거리 오차가 적은 방법을 선택하여 목표기기의 위치를 좀 더 정확하게 측정할 수 있음을 시뮬레이션을 통해 보였다.

Where is a better place to live? In the coming era, this should be more than simply a livable place. It should be an adaptable place that has a flexible system adaptable to any new situation in terms of diversity. Customization and real-time operation are needed in order to realize this technologically. We expect a smart city to have a flexible system that applies technologies of self-monitoring and self-response, thereby being a promising city model towards being a better place to live. Energy demand and supply is a crucial issue concerning our expectations for the flexible system of a smart city because it is indispensable to comfortable living, especially city living. Although it may seem that energy diversification, such as the energy mix of a country, is a matter of overriding concern, the central point is the scale of place to build grids for realizing sustainable urban energy systems. A traditional hard energy path supported by huge centralized energy systems based on fossil and nuclear fuels on a national scale has already faced difficult problems, particularly in terms of energy flexibility/resilience. On the other hand, an alternative soft energy path consisting of small diversified energy systems based on renewable energy sources on a local scale has limitations regarding stability, variability, and supply potential despite the relatively light economic/technological burden that must be assumed to realize it. As another alternative, we can adopt a holonic path incorporating an alternative soft energy path with a traditional hard energy path complimentarily based on load management. This has a high affinity with the flexible system of a smart city. At a system level, the purpose of all of the paths mentioned above is not energy itself but the service it provides. If the expected energy service is fixed, the conclusive factor in choosing a more appropriate system is accessibility to the energy service. Accessibility refers to reliability and affordability; the former encompasses the level of energy self-sufficiency, and the latter encompasses the extent of energy saving. From this point of view, it seems that the small diversified energy systems of a soft energy path have a clear advantage over the huge centralized energy systems of a hard energy path. However, some insuperable limitations still remain, so it is reasonable to consider both energy systems continuing to coexist in a multiplexing energy system employing a holonic path to create and maintain reliable and affordable access to energy services that cover households'/enterprises' basic energy needs. If this is embodied in a smart city concept, this is nothing else but smart energy inclusion. In Japan, following the Fukushima nuclear accident in 2011, a trend towards small diversified energy systems of a soft energy path intensified in order to realize a nuclear-free society. As a result, the Government of Japan proclaimed in its Fifth Strategic Energy Plan that renewable energy must be the main source of power in Japan by 2050. Accordingly, Sony vowed that all the energy it uses would come from renewable sources by 2040. In this situation, it is expected that smart energy inclusion will be achieved by the Japanese version of a smart grid based on the concept of a minimum cost scheme and demand response.

본 연구는 문헌연구를 바탕으로 표지디자인의 개념 및 기능, 구성요소를 고찰하고 1999년부터 2002년까지 문학부문 베스트셀러 표지디자인의 사례분석을 통해 표지디자인의 특징을 도출하였다. 독자의 연령과 성별에 따라 표지디자인에 대한 독자의 선호도를 설문조사와 이미지 평가를 통해 책표지 디자인의 조건 및 방법을 제안하고자 하였다. 표지디자인의 선호도 조사에서 연령, 성별에 따라 관심있게 읽는 책의 종류와 책을 구매하는 장소, 표지디자인에 대한 관심도에 차이가 있었다. 또한 여자는 스타일서체를 선호하며, 남녀 모두 한색을 선호하는 것으로 나타났다. 하지만 그 외의 시각적 요소에대한 선호도 차이가 없는 것은 표지디자인이 여러 요소들로 이루어진 통합적인 이미지이기 때문이다. 그리하여 SD법을 통해 통합적인 이미지로써 표지디자인에 대한 평가를 실시하였다. 그 결과 지나친 추상적 이미지는 명료성이 떨어져 의미전달이 어려운 것으로 나타났다. 또한 스타일 서체가 주를 이룬 표지디자인이 독특성, 명확성에서 높은 평가를 받았다. 비주얼이 뛰어나다고 해도 기능적인 면인 의미전달에서 뛰어난 것과는 차이가 있었다. 이 논문은 시각적 요소만을 한정하여 살펴보았다. 향후 표지디자인을 구성하고 있는 요소들인 재료, 재본, 형태 등에 따라 독자의 선호에 미치는 영향에 대한 연구가 진행되어야 할 것이다.

Every single company in the world makes a huge amount of effort so as to not only cut down the physical distribution cost but promote the efficiency. In the government's respect, especially, they expect to maximize the synergy by unifying the physical distribution. For that reason, it relevant for all kinds of a distribution strategy to get rid of unnecessary distribution centers and to integrate distribution centers by unifying and rearranging the distribution centers that are hardly efficient. Most enterprises in Japan, related to making and distributive, have got a tendency to decentralize their distribution centers in a wide scope of the whole nation. In the meantime, they seem to get a move to become a great-sphere distribution center. Many similar cases in Korea, Koon-Po distribution center, Yong-In distribution center, are not expected to function properly. With a rate of trading products expanded, a new strategic physical distribution is needed to turn the way of depending on building up a new distribution center into the way of unifying and rearranging a distribution center. Therefore, this study aims to identify the optimal method of unifying and rearranging a distribution center, compared to the cost which takes place in a large number of distribution centers.

The main objective of this study is to present a fast and reliable approach to predict the swelling potential of clay-bearing rocks. Investigations showed that there is a good correlation between the swelling potential of a rock and its desire to absorb water due to its clay content which could be measured using the "Contact Angle" test as one of the most common ways to determine the wettability. In this test, the angle between a water drop and the flat rock surface on which it rests is measured. The present method is very fast and returns repeatable results and requires minimal sample preparation. Only having a saw-cut surface of a sample with any shape is all one needs to perform this test. The logic behind this approach is that the swelling potential of a rock is a function of its mineral content and molecular structure, which are not only distributed in the bulk of the sample but also reflected on its surface. Therefore, to evaluate swelling behavior, it is not necessary to wait for a sample to get wet all the way to its "internal structure" (which, due to the low permeability of clay-bearing rocks, is very slow and time-consuming). Instead, one can have a good sense of swelling potential by studying its surface. Parametric studies on the effect of moisture content, porosity, and surface roughness on the contact angle measurements showed that using a saw-cut oven-dried sample is a convenient way to evaluate the swelling potential by this method.
