The purpose of this study is to examine the current status and achievements of research on Chinese population history, and to present reliable long-term statistics on Chinese population history through comparative analysis of related data. This study is necessary for the following reasons. First, with the help of population figures, historical events can be described more accurately. Second, with the help of population figures, you can have more diverse perspectives. Third, newer discoveries and new explanations can be made with the help of recent research results rather than old data. What I did in this study was: First, the usefulness of the previous papers on the Chinese population history was reviewed by collecting as many as possible. Second, almost all books on Chinese population history were collected and reviewed. As a result, "Chinese Population History"(2000~2002) by Ge Jian-xiong and four others was evaluated as the best. Third, based on this book, the state of population change from the end of the Warring States period to the present is summarized in a chart, and a brief explanation is attached here. Those interested in China"s ancient population history should first refer to the books written by Ge Jian-xiong and others. However, this paper deals with long-term population history. Therefore, if you need knowledge about the population history of a specific dynasty or a specific region, you will have to look at the data that has been studied narrowly and deeply about the period and region. It is also necessary for future academic development to summarize and introduce existing research results. This study is the first to do such a work on the population history of China in Korea. Researchers interested in China"s population history will be able to quickly and easily understand the current state of China"s population history research by reading this paper.
이족 보행 로봇의 보행 안정화 및 RFID를 이용한 경로 추종에 관한 연구

이족 보행 로봇을 실생활에 적용하기 위해서는 다양한 환경에서의 강인한 보행 뿐만 아니라, 현재 위치를 인식하여 목표 위치로의 경로를 생성하고, 경로를 추종하는 기능이 요구된다. 최근에 많이 사용되고 있는 RFID는 이동 로봇의 위치인식 및 경로 생성에 손쉽게 활용이 가능하다. 그러나 이족 로봇은 보행시에 불안정성을 내포하고 있어 주어진 경로에서 벗어나기 쉽다. 본 논문에서는 FSR(Force Sensing Resistor)센서, 자이로와 가속도 센서를 이용하여 이족 보행 로봇의 보행 안정화 방법을 제안하였다. 또한 양발에 RFID 센서를 장착하여 이족 보행 로봇의 위치 인식 후 경로를 추종하는 알고리즘을 제안하였다. 제안된 보행 안정화 알고리즘은 실제 제작된 이족 보행 로봇을 이용하여 비평탄 지형에서 실험하여 검증하였으며, 경로 추종 실험은 RFID센서를 로봇의 발바닥에 장착하여 평탄 지형에서 보행실험을 통해 검증하였다. In order to apply a biped robot in real world, the robot requires a robust walking and a function of localization, path planning and navigation. Recently, localization and path planning using RFID of mobile robot has been studying. However, when the biped robot walks, it has unstability and tends to leave the path. In the paper we propose a method of walking stabilization using FSR(Force Sensing Resistor), Gyro and accelerometer for the real biped robot. Also a path tracking algorithm using RFID sensor attached in robot"s foot is proposed based on localization of the robot. The proposed algorithm is verified from walking experiments using real biped robot on uneven terrain and path tracking experiments on the RFID environments.

This thesis has been done as a part of work seeking how to deal with "religion" while studying and educating Chinese Culture. Although religion plays an important role on the formation and change of culture, it doesn"t seem that there is any appropriate studying and education going on in the Chinese culture academy. In this respect, our research will provide significant discussion to the Chinese culture academy. To make the proper discourse of religion in Chinese culture academic field, we have two long term goal: First, we will argue the Confucianism as a religion. Through this argue, we expect Confucianism would be referred in Chinese religion discourse. Second, we will investigate whether Confucianism still do an effect on Chinese as religion even in 21 century. In this thesis, we researched the first part of the goal. The summary of our research so far is as follows. Confucianism in Chinese culture corresponds to Christian religion in the western country. It is a fundamental idea that has shaped Chinese" thought and action for 2,500 years. But Chinese culture scholars hesitate to admit Confucianism as religion. Because their definition of religion has a certain limitation. The definition of religion can be divided in a two way: a substantive definition and a functional definition. A typical example of a substantive definition is to consider religion as "the faith for the spiritual being"(Tylor, 1871). According to this definition, Confucianism is not religion. The good example of a functional definition is that of A. N. Whitehead. "A religion can be defined as a system of general truths which have the effect of transforming humanbeing’s character when they are sincerely held and vividly apprehended."(Whitehead, 1926[2003:166]). According to this definition, Confucianism has been working as religion for Chinese. When studying religion, religion scholars prefer a substantive definition and sociology scholars prefer a functional definition. For culture scholars, it is more useful to choose a functional definition when they research the conduct and the habit of a man. Whitehead(1926[2003]) divides lots of religions into the following 2 types, and describes how each religion functions for the formation of human character. One is communal religion and the other is rational religion. The culture of a region which mainly believes rational religion tends to stress individualism and low-power distance. On the contrary, the culture of a region which believes religion of the community takes on collectivism, high-power distance. Through this, we can presume that religion and culture has considerable correlations. The biggest achievement through the research is that we could invite Confucianism to the Chinese religion discourse field. Though Confucianism has actually functioned as religion, it has not been admitted as religion in the view of substantive definition. Futhermore, it is another achievement of this study to get a model with which we can analyze the religious property of Confucianism.

Network and network functions virtualization (NFV) promise a number of attractive benefits and thus have driven mobile network operators to transform their previously static networks to more dynamic and software-defined networks. In this article, we share a mobile network operator’s view based on implementation and deployment experiences in the wild during the past few years towards a software-defined 5G core network. More specifically, we present a practical point of view from mobile network operators and elaborate on why some of the virtualization benefits such as total cost of ownership (TCO) reduction are not easily realized as initially intended. Then, we describe 5G visions, services, and their requirements commonly agreed across mobile operators globally. Given the requirements, we then introduce desirable characteristics of 5G mobile core network and its key enabling technologies.
