지능사회의 등장은 급격한 패러다임 변화를 몰고올 것으로 예상된다. 역사상 처음으로 사물이 지능을 갖게 되고, 그 결과 사회의 모든 영역에서 예상치 못한 변화가 초래될 것으로 보인다. 이 글은 지능사회의 변화 방향을 전망하기 위해 우선 세계관의 변화 이슈를 분석하였다. 인간과 자연을 두 축으로 하는 이원적 세계관과 인간-기계-자연으로 이루어진 삼원적 세계관을 비교한 후 '기술이 매개하는 이원적 세계관'을 지능사회의 세계관으로 제안하였다. 이 세계관에 기초하여 지능사회의 패러다임 변화방향을 네 가지로 요약하여 전망하였다. 1. 지능의 외부화, 2. 생산성 폭발, 3. 플랫폼 사회, 4. 자기조직화 사회가 그것이다. 지능기술의 발전으로 인간은 지능증강, 생산능력 제고, 자기조직화 효과 등 다양한 이점을 누리겠지만, 다른 한편으로 기술에 대한 통제력이 약화되어 시스템 실패 가능성도 높아진다. 결론적으로 지능사회의 변화는 가치중립적이기 때문에 인간의 선택과 노력에 따라 유토피아가 될 수도 있고 디스토피아가 될 수도 있다.

The purpose of this study is to find out the difference of sense of self-efficacy and stress encountering strategy of university students under the stress situation depending on the smart-phone user group (addiction group, general user group). For this purpose, the study issues are established as follows. First, it has analyzed what is the correlation of smart-phone addiction, sense of self-efficacy, and stress encountering strategy. Second, it has studied if there is any difference of sense of self-efficacy and stress encountering strategy for the smart-phone user group. In order to verify such study issues, For 1,670 university students in the Chungcheong area, smart-phone addiction scale, sense of self-efficacy scale, and stress encountering method scale were administered. Looking into the study result, first, as a result of the relativity analysis, it displayed the correlation of preference of test difficulty, self-control efficacy and important negative from the smart-phone addiction and sense of self-efficacy. In addition, all sub-variables of smart-phone addiction and avoidance orientation from the stress encountering strategy displayed the important positive correlation, and from the smart-phone addiction, the virtual world orientation and pursuit of social-support displayed the important negative correlations, and all sub-variables (interference with ordinary living, virtual world striving direction, withdrawal, resistance) of smart-phone addiction and problem solving-orientation displayed the negative correlation. Second, as a result of verification for the difference of the smart-phone addiction group and general use group following the sense of self-efficacy, the general use group is shown to have higher self-control efficacy sense than the addiction group. And third, as a result of verifying the difference of stress encountering following the smart-phone addiction group and general use group, the addiction group is shown to be lower than the general use group in terms of social support pursuit and problem solution orientation with the avoidance orientation shown to be higher. This type of result is expected to provide the base data when developing the smart-phone addiction preventive education program by finding out in details for the characteristics of smart-phone addiction group for university students.

네트워크 트래픽의 연구 동향은 LAN, WAN 및 VBR 비디오 트래픽이 통계학적으로 자기 유사과정에 의해 더욱 더 잘 모델링화 된다는 사실을 입증하고 있다. 이것은 기존의 단기간 의존성만을 고려한 포아손 과정에 비해 다른 이론적 특성을 가진다. 즉 광범위한 시계열상에서 aggregation의 정도가 변하더라도 통계학적으로 동일한 특성을 지니게 된다는 것이다. 본 논문에서는 이러한 자기유사과정을 갖는 데이터를 실시간 운영중인 네트워크로부터 측정하여 트래픽을 모델링하고, 비교분석하므로서 다양한 데이터를 지원하는 초고속 네트워크의 성능분석에 적용할 수 있으리라 여겨진다.

Haizi, who ended his life with suicide on the railroad at the age of 25, is a poet who implemented his unique poetic world alone without belonging to any of the existing Chinese poetry schools in the 1980s. The process that Haizi reveals self-inside through a poetic work is rather to hide self-inside paradoxically, too. Accordingly, even a work of figuring out the real intention, which is hidden in poetic dictions that he selected, will be meaningful. In this sense, this study tried to inquire into the poetic imagination and self-image that were revealed in poetry focusing on "Spring, Haizi of 10 People", which is a work of having his name as topic, with having been written at the time of suicide, among Haizi's many poetic works. In addition, it figured out Haizi's private conscious world through analyzing the poem titled "Facing the sea with spring blossoms", which was created ahead of death same as "Spring, Haizi of 10 People". Thus, the aim was to look back on significance of his death and to broaden the width of understanding about Haizi's poetry. As for Haizi, the death can be regarded as the completion of 'performance,' which is a kind of Haizi's own final art form. Hence, Haizi's suicide needs to be seen from the perspective dubbed the continuity of creation through this performance, not the discontinuance of creation caused by 'intended death' that the poet himself selected. In the wake of pursuing the poetic world of a gifted poet Haizi, who died early, that this study examined, there will be any poet of Korea who is recalled naturally. One poet will be first recalled Yi Sang, who is a poet and a novelist of having been broadly known. Another poet is overlapped Gi Hyeong-do, who had been active as a poet and a journalist of having been dead after living in the similar period to Haizi. A comparative analysis among works by these Korean and Chinese poets has similarity beyond the temporal space. A research on this is thought to have value of being considered a little more deeply and generally hereafter. Still, this study mentioned only possibility of a comparative research on this.

A global ultrasonic sensor system for self-localization of a mobile robot is proposed in this paper. The global ultrasonic sensor system consists of three or more ultrasonic transmitters fixed at some positions in the world coordinate and receivers in the moving coordinate of a mobile robot. In this global sensor system it is easy to get state vector of the mobile robot in the world coordinate from the distance information between each ultrasonic transmitter and receiver. An extended kalman filter algorithm is used to process the noisy ultrasonic signal and to estimate the state vector. In case of using several independent ultrasonic transmitters, it is necessary to avoid the cross talk among the ultrasonic waves and to synchronize between each ultrasonic transmitter and receiver. The small sized radio frequency modules are adopted to solve the cross talk and the synchronization problem Computer simulation and experiments are carried out to verify the effectiveness of the proposed ultrasonic sensor system.

Until recently, Japanese cuisine was known only for sushi and was still considered exotic outside the archipelago. However, today the number of specialized restaurants which serve other traditional foods is constantly increasing all over the world, making Japanese gastronomy one of the most influential. Japanese government has supported the promotion of national cuisine worldwide in different ways, making washoku (Japanese traditional cuisine) one of the main elements of Japan's soft power and cultural diplomacy. In this paper, I will analyse the connection between Japan's gastrodiplomacy, defined as the use of typical food and dishes as an instrument of soft power, and Japan's food security strategy. I will argue that the strategy of promotion of washoku worldwide is not a mere act of popularization of Japanese food but it is strictly related to the issue of the low self-sufficiency rate of the country, as the main objective of the government is the raise of food export, in order to foster agricultural production and improve self-sufficiency.
