To understand the oceanographic characteristics of Hupo coastal waters as regards the East Korean Warm Current and the North Korean Cold Current, current direction and velocity were investigated by deploying a current meter in Hupo coastal waters during the summer and fall of 2007. Wind data were obtained from the homepage of the Korea Meteorological Administration. Water temperature was measured using a temperature meter attached to the current meter and a mini log. During summer, a south wind prevailed, while during the fall the wind blew from the north. Cold surface waters occurred on a large scale in summer, while in the fall, warm bottom water occurred frequently. After mid-November, when the surface water was cooler than $15^{\circ}C$, there was no difference in water temperature between the surface and bottom layers.

Generalization of the web, development of one-person media such as the blog and mini homepage, and integration of video digital devices have generalized multimedia video services on the web. However, flash videos, the previously used bit map-based multimedia videos, exhibit problems like the waterfall phenomenon, lag phenomenon, or non-synchronization of audios or videos. Thereupon, This study is conducted to suggest a converting technique to provide efficient web video service on the web by solving problems of bitmap-based flash video through file format-converting software and movie editing programs. And this paper also conducts experiments on five videos for 13 CODECs and analyzes converted results comparatively. The recommendable method considering the characteristics of each videos is to utilize MainConcept H.264 Video CODEC using SWF2Video pro. The result of this research can be used to produce web videos on the web more effectively.

Current information-oriented society is expanding rapidly with the huge change to our society from the information revolution emerged in mid '50s. Information technique such as computer, communication satellite and cable technology play their in this information-oriented society, and in 1980s, digital technique was adopted to media, inviting new phenomenon in communication of overall society. Expectations and hope for new trends and changes from digital era flourished when we entered into new Millenium, the 21st century. Since then we have gone through changes in years from analogue to digital. Now the word 'digital' is conceived in unified manner in almost every fields and influences overall society, changing our life pattern rapidly. Modern society had demanded some speedy and bidirectional communication tool in shifting digital era, and resulted from that was a new culture, Now the society changes more and more quickly under the speedy information sharing. From that perspective we need to establish the aspects of sensibility expression, which is one feature of the communication. The sensibility-oriented digital was originated from the human nature, which counts emotion and composure much. To satisfy the human nature a new cultural value which transcend a traditional one is needed. And the sensitivity expression to meet the need is one communication tendency in digital era. Digital era has totally different social qualities from that of analogue era. In digital era, prompt respond to rapid change and creativity combined with sensitivity are needed. Therefore a man with sensitivity would be more outstanding than a man of intelligence. The picture of digital and analogue in our society consists of two axis one is analogue axis like retrospective trend, admiration for nature , oriental thought etc. , and the other is the digital axis of internet and information technology. Sensibility can be widely interpreted as analogue thinking. It is surely different from the plain retrospective trend or nostalgia for past. It is a tendency that digital technology is used and cooperated with the emotion in human nature, In this paper we suggest the sensitivity expressions in detail through the study cases including both sides of digital and sensitivity expressions such as 'Bravo your life' advertising campaign of Samsung Insurance, MP3 advertising campaign, and 'Mini-homepage' of Cyworld. Under the circumstances the main direction of communication is oriented to human. This study's purpose is to think the true meaning of this digital era, to overcoming its weaknesses, such as over-dependency on technique and selfish individualism and to harmonize digital and sensitivity expression. The sensitivity-oriented expression than the reason-oriented one is expected to be put forth in whole media, and this is a more efficient tendency under the shifting digital era.
