Inspired by the multi-scale nature of hippocampal place cells, a biologically inspired model based on a multi-scale spatial representation for goal-directed navigation is proposed in order to achieve robotic spatial cognition and autonomous navigation. First, a map of the place cells is constructed in different scales, which is used for encoding the spatial environment. Then, the firing rate of the place cells in each layer is calculated by the Gaussian function as the input of the Q-learning process. The robot decides on its next direction for movement through several candidate actions according to the rules of action selection. After several training trials, the robot can accumulate experiential knowledge and thus learn an appropriate navigation policy to find its goal. The results in simulation show that, in contrast to the other two methods(G-Q, S-Q), the multi-scale model presented in this paper is not only in line with the multi-scale nature of place cells, but also has a faster learning potential to find the optimized path to the goal. Additionally, this method also has a good ability to complete the goal-directed navigation task in large space and in the environments with obstacles.

Since sulfur dioxide is released from the oxidation of sulfur in fuel, the level of $SO_2$ in industrial areas can be effectively managed by optimizing the allocation of fuels: the fuel should be allocated to each industries so as to achieve the air quality goal in the area with minimum fuel cost. The solution for this can be by solved using linear programming technique incorporated with the Gaussian dispersion equation. When this method was applied in Ulsan Industrial Complex, 39.3% of fuel expense could be saved compared with the present uniform fuel policy. With this method, bituminous coal generally was allocated to big emission sources such as power plants or to industries sparsely located in remote areas, and LPG or low-sulfur oils to small or medium-size sources in dense indurstrial aras. However, the particulates emission will increase with this policy, because it maximizes the use of coal within the limit to achieve the air quality goal in the area.

This paper aims to review and analyse the introduction process of performance management system(PMS) in the R&D sector. It also examines initial problems and future policy directions of the new system. Theory part deals with various approaches to the PMS and the relation between research evaluation and performance management. The paper then describes how the PMS has been introduced in the National R&D Program by the MOST in terms of the contents of strategic goal, performance goal and performance indicator together with their development process. After this, it captures problems arising in the initial phase and then suggests how they should be solved on the ministerial and cross-ministerial level. Discussed are following topics: lack of strategic planning, grouping of heterogeneous sub-programs, duplication between the OMS and other existing research or performance evaluation. The paper finally suggests policy implications using the logic model which has been developed in a series of recent international conferences.

Incheon, South Korea, is a rapidly growing port city that has long held an important role in the country. While for most of its history it has been considered more of a coastal extension of Seoul, it is now trying to grow from that role and become a global city. National and local initiatives and acts have led to the Incheon Free Economic Zone (IFEZ). This large zone connects three smaller districts into one large project. The goal of the project is to assert Incheon as its own city and go beyond its role as merely a gateway to Seoul. However, as most large-scale projects go, there are multiple issues and constraints faced by the IFEZ. This paper analyzes the project and gives critique on how the project could possibly achieve its goal more quickly.

The purpose of this paper is to analyze the functional changes of local educational authority policy based on the systems thinking perspective using causal loop diagrams. In the past, the main function of the local educational authority was to manage and supervise schools. Through this policy, local educational authority would be transformed into a support agency. However, this policy did not achieve the goal, was to cause confusion and require improvement. This study shows structured causes of the problem based on systems thinking. These diagrams make it possible for educational policy makers to provide ideas, although they have some complicated environment. The findings indicate that based on systems thinking in this policy can help those who related to policy decision than existing diagnosis method.

The purpose of this study is to compare the laws and policies relating to work-family balance with foreign cases, and to analyse the problems in implementing those laws and policies. For these purpose, this study compares family leave policies, working hams policies, public care policies in other countries. And these laws in Korea are shown. This study also analyse the policies for work-family balance in labor policy, family policy, gender policy and saeromaji plan. The results are as follows; policies for work-family balance are limited to child care and family leave. Laws for family leave are various and proper. But implementing rate of policy goal is low and a few people can benefit by those laws and policies. So, wide-range policies for work-family balance which all the families can benefit are needed.

본 연구는 지금까지의 우리나라의 지역개발정책을 평가하고, 현황 파악과 이론적 검토를 통해 향후 지역개발정책의 목표와 전략에 대한 정책적 함의를 도출하는 것을 목적으로 한다. 우리나라의 지역정책은 일관되게 지역 간 균형을 추구하는 측면이 강했는데, 경제학적 관점에서 보았을 때 인위적인 지역 간 격차 완화, 특히 수도권과 비수도권 간 격차의 완화는 효율성뿐만 아니라 공평성을 저해할 가능성이 있다. 또한 우리나라의 지역 간 격차를 파악하고 OECD 주요국들과 비교한 결과, 우리나라의 인구 및 소득 집중도가 높은 것은 사실이나 지역 간 소득수준이나 여타 생활여건의 격차가 크다고 보기는 어려운 것으로 나타난다. 따라서 향후 지역정책은 인위적으로 경제활동을 재배치하여 지역 간 균형을 추구하기보다는 각 지역의 자생적 성장능력을 키워주는 데 주력할 필요가 있다. 이를 위해서 지역개발에 대해 현재 중앙정부가 가지고 있는 각종 권한을 대폭 지방으로 이전하여 지방의 자율성을 강화하는 한편, 지역의 성장은 궁극적으로 지방정부가 책임지도록 책임성을 부과할 필요가 있으며, 중앙정부는 지역발전을 위한 정보와 인력을 제공하는 등 건설적인 조력자로서의 역할을 담당해야 할 것이다.

This article was trying to suggest an agenda and alternatives of home health care policy for the future home care growth and development and examine the significance of new health care law and regulations. In addition. It was to analyze and drive the home care system problems. of which was made an announcement on the 11th of April. that home health care project must be centered from the nationwide general hospital. As we have learned from the developed countries, the home health care have been closely related health care policy among the field of nursing area. Therefore. we need to understand our national health care policy and need to predict the future direction and goal of our home health care policy in order to enhance the growth and activation of health care system. Additionally. we also need to have a vision and ability to develop under our own health care policy with systematic and rational home care business escaping from past perspective and standpoint. We must create a master plan of home care system to fulfill one part of system of the function and an important role in order to pursue an advanced health care plan under our system. For instance. in the 21th century as we establish a master plan for the growth of our country home care plan with improving plan systematically and also we need to produce many highly qualified researching and good personal who can develop and maintain the system efficiently. Specially. based on the unique characteristics of our health care system and the direction of development of plan, we need to find and correct the problems which we have faced the present time, so that we can provide and reach the goal of advanced health care system which our government want to pursue. Finally. we have to strive our best effort to make our home health care system can be positioned and stand the right direction to have the benefit for every individual citizen in our country.

Strategic decision on the execution of national security improvement project is greatly important for the present and future national security. Though, the importance of strategic decision, decision making process has been executed under one-way thinking framework. This research provides a decision-making tool with make-or-buy approach for the national security improvement policy execution methods: foreign purchase and military R&D project, and, via simulation, confirms dynamic change of military capability index respect to change in ratio of foreign purchase and military R&D. A result shows that current ratio of foreign purchases and military R&D is insufficient for national security improvement policy goal. Applying the model from this research provides an appropriate ratio for short term and long term defense strategy and policy goal, and consequent result of increase in national security capability. Thus, this research model can be effectively utilized for national security improvement project.
