Lookup-Table (LUT) based fuzzy controller for obstacle avoidance enhances operations faster in multiple obstacles environment. An LUT based fuzzy controller with Positive/Negative (P/N) fuzzy rule base consisting of 18 rules was introduced in our paper$^1$ and this paper shows a 50-rule P/N fuzzy controller for enhancing performance in obstacle avoidance. As a rule, the more rules are necessary, the more buffers are required. This paper suggests LUT sharing method in order to reduce LUT buffer size without significant degradation of performance. The LUT sharing method makes buffer size independent of the whole fuzzy system's complexity. Simulation using MSRDS(MicroSoft Robotics Developer Studio) evaluates the proposed method, and in order to investigate its performance, experiments are carried out to Pioneer P3-DX in the LabVIEW environment. The simulation and experiments show little difference between the fully valued LUT-based method and the LUT sharing method in operation times. On the other hand, LUT sharing method reduced its buffer size by about 95% of full valued LUT-based design.

As vehicle sharing service is being widely used in China. The sharing economy appeared to be a way to make people's lives more convenient and to utilize limited resources efficiently. Sharing economy companies have created an app to satisfy users' needs with providing more benefits. Although research on vehicle sharing services has been continuously conducted at the level of the sharing economy, there are not many empirical studies related to the perception of the sharing economy from the consumer's point of view. In this sense, this study considered the perceived relationship benefits (social benefits, economic benefits, psychological benefits, and functional benefits) of Didi chuxing service as the key independent variables influencing users' confirmation and satisfaction, And suggests that users' confirmation and satisfaction are the key determinants of Didi continuance intention . To test the proposed research model, this study conducted structural equation model using 268 data collected on the users who have experience of Didi service. According to the empirical analysis results, This study verifies that: First, social benefits, economic benefits, psychological benefits, and functional benefits are determinants of user's satisfaction. Second, expectation confirmation depends on economic benefits, psychological benefits, functional benefits and social influence, meanwhile, social benefit has no effect on expectation confirmation. Third, expectation confirmation is proved to be a positive predictor of users' satisfaction. Finally, this results indicate that continuous use intention is determined by users' satisfaction.

가상세계는 현실세계를 반영하여 만든 가상의 공간이다. 이러한 공간간에서 여러 사용자들은 서로의 의견을 교환하며 여러 가지 작업을 한다. 이러한 작업들을 이벤트라고 부르며 기존의 다중 참여자를 지원하는 브라우저들은 객체에 대한 이벤트가 발생했을 대 모든 사용자에게 똑같은 화면을 보여줌으로써 사용자의 소극적인 의사표현만을 제공하였다. 그러나 사용자에 따라 이벤트가 발생했을 때 보고싶은 객체의 위치나 크기 등이 다를 수 있고 때로는 자신의 작업 중에는 이벤트의 발생을 알고 싶지 않은 경우도 있다. 따라서 본 논문에서는 이러한 사용자들의 욕구를 만족시키도록 객체의 이벤트가 발생하였을 때 화면을 표현하는 여러 가지 방법(Presentation Level Sharing, View Level Sharing, Object Level Sharing)을 제시하고 사용자로 하여금 선택하여 볼 수 있도록 제안한다. 또한 이벤트 발생시 표현 방법에 따라 객체를 포함한 영역의 크기도 함께 결정 할 수 있도록 한다.

The module UPS can flexibly implement expansion of power system capacities. Furthermore, it can be used to build up the parallel redundant system to improve the reliability of power system operation. To realize the module UPS, load sharing without interconnection among parallel connecting modules as well as a small scale and lightweight topology is necessary. In this paper, the three-arm converter/inverter is compared with the general full-bridge and half-bridge topology from a practical point of view and chosen as the module UPS topology. The switching control approaches based on a pulse width modulation of the converter and inverter of the system are presented independently The frequency and voltage droop method is applied to parallel operation control to achieve load sharing. Two prototype 3kVA modules are designed and implemented to confirm the effectiveness of the proposed approaches. Experimental results show that the three-arm UPS system has a high power factor, a low distortion of output voltage and input current, and good load sharing characteristic.

This paper as the basic study aiming the establishment of nursing theory according to Korean culture, is made to reveal the types of recognition about concepts of health immanent in Korean who have the health view, completely mixed with traditional oriental medicine and Confucianism and Buddhism and Shamanism and european scientific medicine, etc. This paper is using the Q-method, which is greatly effective in measuring the individual subjectivity, to collect rightly the concepts of health of objects. This analysis shows us the 4 types of recognition about concepts of health immanent in Korean as follows. Type Ⅰ: modern self-searching type(現代的 自己 追求型), Type Ⅱ: nature-sharing type(自然 共有型), Type Ⅲ: meaning-intentional altruism(意味 指向的 他者 中心型), Type Ⅳ: oriental adaptational type(東洋的 順應型). The men belonging to type Ⅰ have positive and self-searching view of health. They are not only interpreting the concept of health scientifically, but also positively accepting the oriental concept of health. The men belonging to type Ⅱ have strong tendency of down-to-earth. They not only have the naturalistic view of health as Taoist, but also carry the weight in the family and neighbour and regard co-sharing as excellent virtue. The men belonging to type Ⅲ are positive altruists, pursuing the meaning of life and at the same time setting the importance to the good value system. Naturally they care more the family and neighbour than themselves. The men belonging to type Ⅳ have oriental view of the world characterized by nature-adaptation. They positively agree to the Shamanism, Buddhism, Confucianism and Oriental concept of health. In conclusion, in all types we can see that Korean understand the harmony of man and nature as fundamental principle of heath and carry the more importance to the mind(心) than body(身) and at the same time esteem more the family-centric, oriental and organic community than individual. All above facts is immersed in the concepts of health of Korean as a common denominator.
