Science and technology are deeply based on the invention of photography. The images that were made through machines and scientific process were not just delicate images. Photography was used wherever accurate record and realistic description were needed, such as public culture, art, advertisement, science research and so on, so it became an important part of anthropologic culture. However, the history of photography in the present photography education mainly deal with photographic tendency of famous photographers, the change of art paradigm by time period, social changes through big wars, thus there is a lack of diverse perspective in the history of photography, such as technological perspective. In this study, the history of photography was examined through science and technology, and analyzed how photography was affected and changed by the stage of important technological accomplishment. From this point of view, It will be helpful to understand modern photography, and meaningful to be a good reference. Furthermore, by understanding that photography relies on technology, the people who majored in photography will realize how important studying photographic technology and theories is.

Wireless devices can communicate between each other without existing infrastructure in mobile Ad-hod network. Ad hoc networks can be used under difficult conditions, where it is difficult to construct infrastructures, such as shadowing areas, disaster areas, war area, and so on. In order to support to considerable and various wireless services, more spectrum resources are needed. However, efficient utilization of the frequency resource is difficult because of spectrum scarcity and the conventional frequency regulation. Ad-hoc networks employing cognitive radio (CR) system that guarantee high spectrum utilization provide effective way to increase the network capacity. In this paper, we simulate and compare the performance of conventional single and cooperative spectrum sensing with CR system using ad-hoc networks in additive white Gaussian noise (AWGN) and Rayleigh channel model. And we demonstrate performance improvement by analyzing the system performance.

The military technological surprise has been delivered in many warfares as a surprise tactic. It can be used both strategic and tactical level. As the weapon systems have been escalated their capabilities by the modern science and technology advancement, the possibility of technological surprise has been increased. Technological surprise can spring from sources like scientific breakthrough in the laboratory, rapid fielding of known technology, and new operational use of an existing weapon and technology. There are 2 types of surprise, known surprises are those which the nation should have known but did not adequately prepare, and surprising surprises are those which the nation might have known but which were buried among other possibilities. The nine cases of modern technological surprises are presented and the sources and types are analyzed. The recommendations for the ROK MND to prepare for the future technological surprises are proposed.

The domestic game industry is diversifying itself in terms of game contents. The existing contents have limits when it comes to satisfy various needs and tastes of users. A scenario which successfully absorbs the players and users of a game may affect the whole game structure. Companies also introduce new contents to seize new customers. Thus, contents are considered more important than the past. Now that companies are able to produce various forms of contents and products out of one specific content, the development of new, user-satisfying contents can affect other fields of the industry. Thus, they are now found in one of the top positions in the business hierarchy. But game developers and experts concentrate more on other factors and environments of games, slowing down the growth of contents development. Therefore, this study focuses more on contents as an essential attribute to game production, especially scenario making. How changing results of a synopsis, as a part of a scenario, affect the preference of game users was the main focus of the study. The result of the study should suggest a positive direction for contents and scenario development.

In every country, land has always been considered a particularly important resource and property. For Vietnam, a populous country with a relatively narrow cultivated land, the land is even more valuable because property is scarce in the process of building and developing the nation. Therefore, land administration is highly valued by the Vietnamese government and is a big priority. The study of land law and land policy in Vietnam from 1945 to present is a comprehensive view of the changes in land administration policy in Vietnam in each historical period. The study also provides the experiences and lessons learned in the field of land law and land administration in a country that has risen from the ashes of war, has accomplished reunification and has transformed from a centrally-planned economy, a feature of the communist economy, to a socialist-oriented market economy.

Completed in September 1796, Suwon Hwaseong Fortress is a defense facility with 49 facilities spanning 5,744m. During the Japanese occupation and the Korean War, many buildings and walls were damaged, and in 1975, it was restored to its current state through the restoration and restoration project in Suwon. Six of the entire facilities have not been restored by urbanization, of which the restoration of water spaces, including ditches buried in the ground, could be used as a place of rest and viewing for visitors. Tourists visiting Suwon Hwaseong, are satisfied with exploring the historic sites, but feel insufficient for enjoying the natural scenery around the castle. The best way to create a natural landscape in Suwon Hwaseong, where urbanization has been developed, is to create a water space to make you feel the traditional garden. Therefore, the location, shape, and functions of the unrestored water space of Hwaseong Fortress were analyzed through the analysis of 『Hwaseong Seongyeog Uigwe』 and 『Hwaseong Full Map』. The purpose of this study is to derive the traditional landscaping method by analyzing the characteristics of water space.

Ad-hoc networks can be used various environment, which it is difficult to construct infrastructures, such as shadowing areas, disaster areas, war area, and so on. In order to support to considerable and various wireless services, more spectrum resources are needed. However, efficient utilization of the frequency resource is difficult because of spectrum scarcity and the conventional frequency regulation. Ad-hoc networks employing cognitive radio (CR) system that guarantee high spectrum utilization provide effective way to increase the network capacity. In CR based wireless ad-hoc networks, cluster-head decides the existence of primary user using sensing information of primary user from each ad-hoc device. However, it is still defective research to decide cluster head among the a lot of ad-hoc devices. So, in this paper, we show the decision method of cluster head in CR based wireless and detection probabilities of primary user based on decision method of cluster head.
