The world has moved from the Cold War between the east and the west and moved toward the age without idealogy. It places emphasis on economic benefit and welfare of its own nation as its main point With this world trend, in order to sam the competitiveness and the reconciliation of the divided nation the north and the south Korea should be united. Once the north and the south are united, information society will be altered with the huge flow of the civilization. At the same time, the issue of how to operate library policies and system, in which effective acquisition, manipulation, accumulation, and dissemination of information un would be very important. From this point of view, the following conclusions are obtained in this study. Firstly, when building a national library preparing for the national unification. it is essential to introduce 1) the concept of policy and system for information society and 2) that of policy and system which has national-culture as its focus. Secondly, it is essential to prepare the cooperative-structure between libraries prior to the national unification. This kind of cooperation should gradually expand to an extent that allows actual benefits such as building union catalog, inter-library loan system, resource sharing, standardized cataloging rules, and exchange of dissertation... etc. Thirdly, developing the library policies and systems for the national unification must be based on the concept of the mutual cooperation as inter-dependent model rather than on the concept of the incorporation-absorption as a dominant model. The next point the principles of the followings in preparing the library policies should be considered: 1) free-competition, 2) revolution of consciousness through the social education, 3) independence and love for humanity, 4) scientific or reasonable thinking, 5) job responsibility, 6) democratic citizenship, 7) mind far collective life, 8) spirit of public interest 9) globalization In addition, the model of the library systems preparing for thenational unification should include the followings : 1) uniformity of library system and its authority, 2) establishment of research institutes for library policy and system, 3) exchange of library establishment and information resources, 4) building library networks, 5) establishment of education systems for the library and information science and enhancement of its quality, 6) modernizing and developing information technology and its transfer. Finally, the libraries in the north and the south has different concepts, goals, information resources, and the different ways of using them. Considering the practical aspects of the libraries and the reasons for their existence, they must structure the mutual cooperative system so as to minimize the shock when confronting the social changes, so-called the national unification.

This study considers the characteristics of the separation of public and private security service during Koryo dynasty, and compares it with the modern security service. Modern day security service's definition of private and public security service was used to distinguish them. Given the different historical settings, it's difficult to argue that the distinction between public and private service during Koryo dynasty was clear, but it can be said that public security service was centered around palace guard and concerns the activities of protest, and military made for the relationship, and private security service was centered around power of DoBang and includes the activities of malingering, and Byolchogun. During the early days of Koryo, protest, district military and soldiers who stay in the palace were all parts of a palace revolt and this institutional improvement of soldiers who stay in the palace was accomplished during King Seongjong's rule. The tradition of a palace revolt can find its roots in the middle military, and after the unification, a palace revolt was reformed into the king's palace revolt of second and the 6th along the course of establishing the nation's system. All of the changes stem from the reformation for consolidating the royal authority. Gyung Dae Seoung wanted to protect himself and he slept with his army night and days and because of that, group of soldiers was created and it was called DOBANG. Some members were from dobang gyeonryong, The forced were powerful because it was gathered with a warriors with extraordinaire martial arts and competent management. Most of the soldiers followed gyeong dae seung because they believed that he has a strong leadership and loves his people, and had a strong faith in him. However, the general gyeong jang had a belief that politics must be reverted to the previous so the relationships between jungbang wasn't smooth. Because of the economic operational problems, due to fraud committed by the mens under his command failed to maintain integrity and was criticised.The misconception also fed up with the emperor and the deepening relationships between the soldiers, his dobang was dismantled. After he took over the dobang, for his personal safety and to strengthen his position he compensated gyeon dae seong's dobang and developed the organization. In the process of extending the dobang Choi chung heon recruited many talented people to strengthen the military base, and also accepted the advice and expanded the power of Dobang. Choi Chung Heon thus consolidated his political gains by weakening the power of the king's army and adjusting the myth, which could've threatened his regime, and this was called Dobang number 6th. Dobang number six got even more powerful by his son named Choi woo, and after ruling, he expanded into a room, and a substantial reorganization of Dobang was developed. And then the creation of yabyeolcho also showed the effect to prevent the crisis. Although the palace guards who were public security service of Koryo Dynasty was still maintained during the military rule era when the royal authority was incapacitated, it was only maintained to have a symbolic meaning as the actual authority including military power was with Choi, the master of Dobang, private security service group. Likewise, during the rule of Choi, private securty service could reign over public security service, and the noteworthy characteristic of Dobang is that it assisted the private soldier groups to seize the military power by reorganizing and modifying military system. Although both differences and similarities can be found when comparing the guards of Koryo Dynasty with those of contemporary society, they have a similarity in terms of the essence of guards that they guarantee the safety of their clients. As for differences, the royalty of Koryo Dynasty and the pursuit of profit of contemporary society are in contrast, and contemporary guards can be seen as the fulfillment of responsibility and duty by free will, whereas guards of Koryo Dynasty were ruled with military coercion.

An autonomous and automatic home mess-cleanup robot is newly developed in this paper. Thus far, vacuum-cleaners have lightened the burden of household chores but the operational labor that vacuum-cleaners entail has been very severe. Recently, a cleaning robot was commercialized to solve but it also was not successful because it still had the problem of mess-cleanup, which pertained to the clean-up of large trash and the arrangement of newspapers, clothes, etc. Hence, we develop a new home mess-cleanup robot (McBot) to completely overcome this problem. The robot needs the capability for agile navigation and a novel manipulation system for mess-cleanup. The autonomous navigational system has to be controlled for the full scanning of the living room and for the precise tracking of the desired path. It must be also be able to recognize the absolute position and orientation of itself and to distinguish the messed object that is to be cleaned up from obstacles that should merely be avoided. The manipulator, which is not needed in a vacuum-cleaning robot, has the functions of distinguishing the large trash that is to be cleaned from the messed objects that are to be arranged. It needs to use its discretion with regard to the form of the messed objects and to properly carry these objects to the destination. In particular, in this paper, we describe our approach for achieving accurate localization using RFID for home mess-cleanup robots. Finally, the effectiveness of the developed McBot is confirmed through live tests of the mess-cleanup task.

According to the Article 86 of the United Nations on the Law of the Sea(UNCLOS) the provisions of high seas apply to all parts of the sea that are not included in the exclusive economic zone, in the territorial sea or in the internal waters of a State, or in the archipelagic waters of an archipelagic State. Article 87 also stipulates the freedom of the high seas. International laws on the flight over the high seas are found as follows; Firstly, as far as the nationality of the aircraft is concerned, its legal status is quite different from the ship where the flags of convenience can be applied practically. There is no flags of convenience of the aircraft. Secondly, according to the Article 95 of UNCLOS warships on the high seas have complete immunity from the jurisdiction of any State other than the flag State. We can suppose that the military(or state) aircraft over the high seas have also complete immunity from the jurisdiction of any State other than the flag State. Thirdly, according to the Article 101 of UNCLOS piracy consists of any act of voluntary participation in the operation of a ship or of an aircraft with knowledge of facts making it a pirate ship or aircraft. We can conclude that piracy can de done by a pirate aircraft as well as a pirate ship. Fourthly, according to the Article 111 (5) of UNCLOS the right of hot pursuit may be exercised only by warships or military aircraft, or other ships or aircraft clearly marked and identifiable as being on government service and authorized to that effect. We can conclude that the right of hot pursuit may be exercised only military aircraft, or aircraft clearly marked and identifiable as being on government service and authorized to that effect. Fifthly, according to the Article 110 of UNCLOS a warship which encounters on the high seas a foreign ship, is not justified in boarding it unless there is reasonable ground for suspecting that: (a) the ship is engaged in piracy, (b) the ship is engaged in the slave trade, (c) the ship is engaged in an authorized broadcasting and the flag State of the warship has jurisdiction under article 109, (d) the ship is without nationality, or (e) though flying a foreign flag or refusing to show its flag, the ship is, in reality, of the same nationality as the warship. These provisions apply mutatis mutandis to military aircraft. Sixthly, according to the Article 1 (5)(dumping), 212(pollution from or through the atmosphere), 222(enforcement with respect to pollution from or through the atmosphere) of UNCLOS aircraft as well as ship is very much related to marine pollution. Seventhly, as far as the crime on board aircraft over the high seas is concerned 1963 Convention on the Offences and Certain Other Acts Committed on Board Aircraft(Tokyo Convention) will be applied, and as for the hijacking over the high seas 1970 Convention for the Suppression of Unlawful Seizure of Aircraft(Hague Convention) and as for the sabotage over the high seas 1971 Convention for the Suppression of Unlawful Acts Against the Safety of Civil Aviation(Montreal Convention) will be applied respectively. These three conventions recognize the flag state jurisdiction over the crimes on board aircraft over the high seas. Eightly, as far as reconnaissance by foreign aircraft in the high seas toward the coastal States is concerned it is not illegal in terms of international law because its act is done in the high seas. Ninthly as for Air Defence Identification Zone(ADIZ) there are no articles dealing with it in the 1944 Chicago Convention. The legal status of the foreign aircraft over this sea zone might be restricted to the regulations of the coastal states whether this zone is legitimate or illegal. Lastly, the Arctic Sea is the frozen ocean. So the flight over that ocean is the same over the high seas. Because of the climate change the Arctic Sea is getting melted. If the coastal states of the Arctic Sea will proclaim the Exclusive Economic Zone(EEZ) as the ocean is getting melted, the freedom of flight over that ocean will also be restricted to the regulations of the coastal states.

There are a few tanycytes between the general ependymal cells lining the ependymal layer of the brain ventricle. These cells are considered as modified ependymal cells which possess a long basal process. Tanycytes are known to have an ability to communicate by absorbing substances from cerebrospinal fluid and transporting them to the blood vessels and/or to the neurons in the CNS. The third and fourth ventricular tanycytes were mainly studied as subjects but it's rare to find reports about the tanycytes of the area postrema. Glial fibrillary acidic protein is an intermediate filament protein that is expressed especially in astrocytes of the CNS. But GFAP is also found in filament of the tanycytes and its process. Therefore this study was carried out for the examination of the GFAP immunoreactive tanycytes lining the area postrema of the bat, and we also examined the ultrastructure of tanycytes using electron microscope. GFAP immunoreactive tanycytes were located in the caudal portion of the fourth ventricle, and especially mainly in the transitional zone between the floor of the caudal fourth ventricle and ependymal layer lining the area postrema. A few GFAP immunoreactive tanycytes were also found in the ependymal layer lining the area postrema, and some groups of tanycytes were found in the ependymal layer of the area postrema near the floor of the caudal fourth ventricle , The processes of tanycytes were stained deeply with anti-GFAP antibody. Especially the GFAP immunoreactive tanycytes lining the area postrema had very long processes that cross the whole width of the area postrema. In the electron microscope, the cell body of ependymal tanycyte was located on the ependymal layer and had a long basal process. Intermediate filaments were observed around the nucleus and well developed in the process of tanycrte. Longitudinal oriented long mitochondria and a few lipid droplets were also found in this process. After immunocytocheical staining, the gold particles were found only in the intermediate filaments. We could not determine the function of the tanycytes in the area postrema. Thus, further investigation is required to determine the functional relationship between the tanycytes and the area postrema in hibernating animal, the bat.
