How to manage manhole is to estimate the part without observation and maintain the sewer. To get the information about current flow rate, visiting and measuring specific manhole is positively necessary. Also, there are some problems that accurate measurement of flow rate is difficult and obtaining the information about real-time whole flow rate is impossible. This thesis will easily grasp the accurate location and type of manhole to solve the problems, and provide the manhole system conveying information through direct radio communication with a manhole cover to renewal information of manhole properly. Besides, it intends to save the information about management of waterworks, maintenance of facilities, data for flow rate, and structure of manhole. Using these, it is supposed to offer how to handle manhole. Thus, this thesis delivers the information to manhole and into central servers directly without wire and provides the system and management method for effective maintenance of manhole.

This paper presents the interior space information using 6D-360 degree immersive media video information. And we implement the augmented reality, which includes a variety of information such as position information, movement information of the specific location in the interior space GPS signal does not reach the position information. Augmented reality containing the 6D-360 degree immersive media video information provides the position information and the three dimensional space image information to identify the exact location of a user in an interior space of a moving object as well as a fixed interior space. This paper constitutes a three dimensional image database based on the 6D-360 degree immersive media video information and provides augmented reality service. Therefore, to map the various information to 6D-360 degree immersive media video information, the user can check the plant in the same environment as the actual. It suggests the augmented reality service for the emergency escape and repair to the passengers and employees.

In a serial link system, various types of serializers exist. However, some types of serializers are not appropriate to be used in applications, such as high-speed interface, of which the required eye size of the output is limited. With analysis and comparisons of serializers, this paper shows that by selecting a proper serializer, an improved transmitter for a high-speed interface environment can be implemented.

Under the civil law system, the individuals were regarded as free and equal each other. Accordingly, employees had equal position with their employer and the Government had the position not to engade in their labor relations. However, it has revealed that labor relations were not equal and free. The emplyees had no choice but to sell their labor in order to survive and to work under employer’s control and direaction which is called as subordinate labor relationship. The Government has begun to protect the employees who were under subordinate labor relationship with their employers by enacting the labor laws. The employees who were not in the subordinate labor relationship were not protected because they were regarded as free and equal and did not need any protection. In this respect, is very important because it plays a role of distinguishing one group of employees who are protected by the labor laws with the other group who are not. In korea, there is no statute which describes the concept and standard of subordinate labor relationship and only the relevant cases explain it. But, many cases do not render the unified position as to the concept and standard of subordinate labor relationship and they have several separate positions. The courts have rendered different positions between labor union law and labor standard law and between one employer and dual employers. The concept of subordinate labor relationship should be established by enacting the proper statutes.
