The purpose of study is to develop the web-contents for web based instruction (WBI) with the Science Fiction Movie (SF) and investigate the effects of application to the science learning. The results are as follows. 1) Science fiction movies for the earth science classes of middle school were selected, that is the Armageddon, the Apollo13 and the Total Recall. They are related to the chapters, the Earth and the Stars in the 8th grade science textbook. 2) The developed WBI materials were applied to the science classes of the 2nd grade in middle school through the Internet Line. and then the changes of attitude on science and recognition on using the science fiction movies to the class were analyzed. The results show that the science fiction movies have so much related to the contents of science learning and the developed WBI materials are effective to the science classes(p<0.05), but no meaningful (p>0.05) to the attitude on the science excluding the students' interest to science learning.

In this paper I try to analyze the trends of f environments, which changes dramatically, on the center of Web2.0 and Geospatial web, and then investigate how these new technologies can be applied in the field of geography. Nowadays international IT companies have provided the internee map which includes whole world. Also, mashup technology based on internet map has also been applied in the various areas. In the study of geography one can utilize the internet map as a basic data for regional study. In addition, I recognize that the collaborative intellectual of the ordinary people as well as expert can be utilized actively in the regional study. But in Korea, the mashup technology based on the internet map is not fully utilized. It is necessary to study the technologies related to the Geospatial web. For example, the study of the Geocoding technology which can locate the user information on the internet map, the technology that can combine the information of Geospatial attributes among the various information widely dispersed over the internet with the internet map, and the technology that can efficiently visualizing data by using wet-based vector graphic etc, is needed.

With the advent of distributed computing and Web service technologies, lots of users have been requiring services that can conveniently obtain and/or support well-assembled information based on Web. For this reason, we are to construct Automatic Linking Support Systems for generating Web-based integrated information and supporting retrieval information according to user's various requirements. Our system organization is based on client/server system. A server environment consisted of automatic linking engine that can provide lexical analyzing, query processing and integrated document generating functions, and databases that are made of dictionaries, image and URL contents. Also, client environments consisted of Web editor that can generate integrated documents and Web helper that can retrieve them via automatic linking engine and databases. For client's user-friendly interfaces, web editor and helper programs can directly execute by down leading from a server without setup them before inside clients. For reducing server's overheads, Parts of server's executing modules are distributed to clients on which they can be executing. As an implementation of our system, we use the JDK 1.3, SWING for user interfaces like Web editor and helper, RMI mechanism for interaction between clients and a server, and SQL server 7.0 for database development, respectively. Finally, we showed the access procedures of automatic document linking engine and databases from Web editor or Web helper, and results appearing on their screens.

The IETF has recently been standardizing the QUIC protocol for HTTP/3 services. It is noted that HTTP/3 uses QUIC as the underlying protocol, whereas HTTP/1.1 and HTTP/2 are based on TCP. Differently from TCP, the QUIC uses 0-RTT or 1-RTT transmissions to reduce the connection establishment delays of TCP and SCTP. Moreover, to solve the head-of-line blocking problem, QUIC uses the multi-streaming feature. In addition, QUIC provides various features, including the connection migration, and it is available at the Chrome browser. In this paper, we analyze the performance of QUIC for HTTP-based web and streaming services by comparing with the existing TCP and Streaming Control Transmission Protocol (SCTP) in the network environments with different link delays and packet error rates. From the experimental results, we can see that QUIC provides better throughputs than TCP and SCTP, and the gaps of performances get larger, as the link delays and packet error rates increase.
