This study reports newly discovered seven forest wetlands in the western part of the Korean Demilitarized Zone-Civilian Control Zone ecoregion. The wetland assessment criteria proposed by National Arboretum were adopted to evaluate four fields: vegetation and landscape, biogeochemical cycle, hydraulics and hydrology, and social-cultural-historical landscape and disturbances. Among seven wetlands located in Gimpo and Paju, five were of the fallow field type and two were of the natural type. A total of 474 plant species were recorded, including nine rare plants, such as the Carex capricornis Meinsh. ex Maxim. Three forest wetlands were sorted into A-grade, three into B-grade, and one into C-grade. Monitoring forest wetlands scattered across the border area ruled by military regulations can be challenging; still, as forest wetlands with high conservation value turned out, further investigations through remote sensing and cooperation by the relevant agencies will be required.

This study examined the flora and community classification in the Forest Genetic Resources Reserves (FGRR) at Mt. Daeseng and Juparyeong to understand the degree of disturbance and the state of forest stand development within the Civilian Control Line (CCL) and to provide baseline data for preservation and management. Of the vascular plants dispersed throughout the study site, there were 98 families, 311 genera, 507 species, 6 subspecies, 65 varieties, and 10 forms, for a total of 588 taxa. Of these, 92 families, 290 genera, 459 species, 6 subspecies, 58 varieties, and 9 forms, for a total of 532 taxa of native plants, were determined to be dispersed around the FGRR at Mt. Daeseng, and 94 families, 259 genera, 364 species, 6 subspecies, 50 varieties, and 8 forms, for a total of 428 taxa of native plants, were confirmed to be dispersed around the FGRR at Juparyeong. There were 21 taxa of endemic Korean plants growing in the FGRR at Mt. Daeseng, with 14 taxa growing in the FGRR at Juparyeong. In terms of rare plants, 26 taxa were confirmed in the FGRR at Mt. Daeseng, and 10 taxa were confirmed in the FGRR at Juparyeong. A Cluster analysis was performed using vegetation data taken from 58 sample plots in each FGRR. The results showed a total of three representative community classifications from Mt. Daeseng: mixed mesophytic forest, Quercus mongolica-Acer pseudosieboldianum, and Quercus mongolica-Fraxinus rhynchophylla communities. Four representative community classifications were observed from Juparyeong: Quercus mongolica-broad leaved forest, Fraxinus rhynchophylla-broad leaved forest, Quercus mongolica, and Quercus communities. On the whole, the species diversity of the communities in Mt. Daeseng FGRR was greater than for the communities in Juparyeong FGRR. At Mt. Daeseng, the mixed mesophytic forest had the highest species diversity index at 1.590, while at Juparyeong, the Fraxinus rhynchophylla-broad leaved forest had the highest species diversity index at 1.319. These study results should serve as useful baseline data for future preservation and management of the demilitarized zone (DMZ) and the surrounding area.

With the growth of airline management, as well as computer and IT security, the international trade in this modern society has been rapidly increasing, Along with the advancing, airplanes have become a universal means of communication. However, the complications associated with airplane safety have also been brought up as a result, the most concerning of which is terrorism. One of the main counterplans for preventing terrorism is Ground security activities the core of Ground security activities is absolute safety for passengers in both passenger terminal and freight terminal. Subastral security refers to physical protection, proximity control and 100% security search and freight guarding of the passengers' possessions, and the personnel's duties to perform such jobs are be! coming more crucial. On the other hand, Airport security check has bee n gradually developing since the 1960's, when hijacking began to take place. Although the airports have been providing more safe and comfortable services to their customers, terrorism is still happening today. When Ground security activities is minute, the users feel displeasure and discomfort, yet considering solely their convenience can brings problems in achieving safety. Since the 9.11 terror in 2001, the idea of improving and strengthening airport security was reinforced and a considerable amount of estate is being spent today for invention and application of new technology. Various nations, including the United States, have been improving their systems of security through public services; public police department is actively carrying out their duties in airports as well. In San Francisco International Airport, private police department is in charge of collection of data, national events, VIP protection, law enforcement, cooperation within facilities, daily-based patrol and traffic control. Under guidance and supervision of national organizations, such as TSA, general police department interprets X-Rays, operates metal detectors, checks passports or IDs and observes reactions to explosives. Under these circumstances, studies about advancement of cooperation and duties of general police department and private police department necessitated: especially about private police department and their training for searching equipments, decrease in number of turn over rate, invention of technology and prior settlement in estate for security. The privacy of the public, who make up the major population of airport passengers, must also be minimized. In the following research, the activities of police departments in San Francisco International Airport will be analyzed in order to understand recent actions of the United States on airport security.
