남북 분단 이후, 남과 북은 상호 간의 동질성을 확보하기 위하여 다양한 교류 사업을 진행하고 있다. 이러한 사업 중에 문화재청과 통일부는 DMZ와 접경지역에 대한 문화유산의 분포 상황을 파악하기 위한 다양한 작업을 진행하고 있다. 이번 글은 이러한 작업 중에 새롭게 확인한 명호리 봉수, 고성리산성과 대강리사지 위치 비정에 대한 재해석, 보호 대책이 시급한 문화유산의 사례를 소개했다. 남북 분단의 현실에서 철저하게 문화유산의 보호 대책을 시행하기에는 어려움이 있지만, 우리 군은 「군문화재보호 훈령」을 제정하고, 「매장문화재 보호 및 조사에 관한 법률」도 준용하고 있다. 특히, 「군문화재보호 훈령」에는 '군사재' 보호라는 가치를 부여하고 있다. 이 때문에 군종별로 문화유산 전담부서의 신설이 필요하다. 그리고, DMZ와 접경지역에 대한 문화유산의 확인과 조사는 꾸준히 진행될 필요가 있다. 현지 조사가 어려운 현 상황에서 고지형 분석과 각종 문헌 조사를 통한 1차 조사는 유효하다. 그리고 향후, 현지 조사를 통하여 수정·보완되어야 한다. DMZ와 접경지역 문화유산에 대한 다양한 조사는 일부 시행착오가 예상되지만, 지속해서 진행될 필요가 있다.

Analytic modeling and computational simulation for the protection of DTV from cognitive radio interference are performed. Protection is achieved by using the protection ratio, which is derived through system modeling and its analysis. On the frequency coordination between digital TV and cognitive radio, an analysis in a co-channel environment, in a rural area in Korea, is performed.

Recently, the terrestrial laser scanner is considered as useful measurement equipment for acquiring a three-dimensional data. In this study, a terrestrial laser scanner which has +/- 2.5cm accuracy is examined whether the terrestrial laser scanner is reliable to present the tendency of landslide movement. The test area is covered by protection blocks, and they are being moved by landslide movement. Landslide movement was detected by measuring the movement of protection blocks. Totally three scenes of test area were acquired during 2004 and 2006. The three scenes of the protection blocks were registered in global coordinate system, then the landslide movement was investigated. The landslide movement detected in the three scenes was evaluated by comparing with landslide movement measured by a total station. Although the measurement accuracy of landslide using the terrestrial laser scanner was worse than the total station, the scanning data showed the tendency of landslide movement of the test area.

본 연구는 1997년 11월부터 1998년 10월까지의 기간 동안 총 11회에 걸쳐 금강 하구지역에서 조류군집의 보호 및 관리방안을 모색하고자 조류군집의 도래 및 서식현황과 서식지 환경의 특성을 조사하였다. 금강하구지역에서 물새의 서식 환경으로 수면이 차지하는 비율이 가장 높았으며, 농경지, 산림, 건물지역, 갈대밭, 갯벌지역의 순으로 나타났다. 총 104종의 조류가 관찰되었으며, 조류의 종수는 4월에 46종으로 가장 많았으며, 개체수는 2월에 51,002개체로 가장 많았다. 수면성 오리류는 하구의 갯벌지역과 하천의 하중도 및 얕은 물이 있는 지 역을 주로 이용하였으며, 갈매기류와 도요·물떼새류는 하구지역에서, 고니류와 기러기류는 상류의 하중도와 십자들 지역에 주로 분포하였다. 이러한 결과로 미루어 보아 지역별 서식환경이 지니는 특성에 따라 연중 다양한 조류가 금강 하구지역을 서식지로 이용하는 것으로 나타났다. 금강 하구지역에서 조류 군집의안정적인 유지와 보호·관리를 위해서는 갯벌, 농경지, 하중도와 하변에 분포하는 갈대밭 등 자연적인 서식환경의 다양성이 유지되어야 할 것으로 판단된다.

Protection of solar cell surface is important to prevent from dust, pollen, sand, etc. Therefore, development of large area antifouling film is urgent for high performance of solar cells. The surface of silica spheres was modified to fabricate large area antifouling film. The surface of monodisperse silica spheres has been modified with 3-(trimethoxysilyl) propylmethacrylate (TMSPM) to fabricate large area photonic crystal. Although the surface modification of silica spheres with TMSPM has been failed for the base catalyst, the second trial using acid catalyst showed the following results. The FTIR absorption peak at $1721cm^{-1}$ representing C=O stretching vibration indicates that the TMSPM was attached on the surface of silica spheres. The methanol solution comprised of the surface modified silica spheres (average diameter of 380 nm) and a photoinitiator was poured in the patterned silicon wafer with the dimension of 10 cm x 10 cm and irradiated UV-light during the self-assembly process. The result showed large area crack and defect free nanostructures.

In the case of the fire to the exterior of the building through openings, the openings of the adjacent building are exposed to the risk of combustion expanding and factors that affect the combustion in the radiant heat and direct flame. Recent five years, fire of the adjacent building indicated that incidence of the 5,134(2.27%) among total 225,934 cases occurred The damage scale of fire expanded was lower than in a single building but casualties(5.46%) and property(25.0%) damage were higher. Therefore, this study provides to analyze the operating status for fire protection equipment of fire-preventing area in the Seoul and to apply measures to improve fire protection equipment according to narrow the distance between the building openings studied.

This paper presents the importance of corrosion control and protection technology with a real case study of heater tube rupture damaged by High temperature H2S-H2 corrosion in the refinery. The heater was operated at the Hydrocracking unit and the operation temperature and pressure was $340^{\circ}C$ and $18kg/cm^{3}$ respectively. Top side of the convection tube was thinned by high temperature hydrogen sulfide and hydrogen gas as a uniform corrosion and finally ruptured under operation pressure. Damaged area (Convection tube zone) was blocked by protection wall, so it was impossible to inspect with conventional nondestructive examination. Instead the elbow area which is out of the protection wall was inspected regularly to evaluate the corrosion rate of convection tube indirectly. However the operation temperature and the phase of the process stream was different between inside the chamber and outside the chamber. As a result, it caused severe corrosion to the horizontal convection tube inside the chamber comparing to the elbow outside the chamber. Finally convection tube was corroded more rapidly than the elbow and ruptured after 13 years operation. Because of the rupture, the heater was totally burned and the operation was stopped for 3 months until it has been reconstructed. To prevent this kind of corrosion problem and accident, corrosion control should be strengthened and protection technology should be improved.

The article considers some issues of criminal law protection of information relations. With the emergence of new types of threats to Ukraine's national security in the field of protection and defense of the state border, the issues of development and strengthening of information protection become especially important. Proper compliance with information legislation also depends on the established responsibility for its violation, which rests on certain provisions of the Criminal Code of Ukraine. It is stated that these norms are placed in different sections and do not have a proper systematization. The article singles out the subjects of information relations in the border area, which are subject to criminal law protection: persons who are not bound by stable relations with the SBGS (who cross the state border of Ukraine, etc.); persons who are members of the SBGS (servicemen and employees); SBGS as a public authority (official and secret information, information about the activities of the agency, its officials, etc.).

Today, the public assistance program in Korea is provided mainly for the livelihood protection beneficiary in urban area. The fact that the urban community-centered program is also applied to the livelihood protection beneficiary in rural area brings about some problems in fitness and effectiveness of resource distribution. The purpose of my study is to present my opinion that the public assistance program for the rural community should be put in practice after being fully distinguished from the urban program for the effective distribution of limited social welfare resources to insure the minimum standard of living and seek the self-support contribution which is the purpose of the public assistance program. The subject for this study were livelihood protection beneficiaries living in both rural and urban area. And the study was carried out in this parts: first, the way of life in them, second, the contents of 6 main public assistance programs being carried out. Total number of the livelihood protection beneficiaries are 279 case: 143 case from 15 Dong in 5 cities, and 136 case from 15 Myun in 5 counties. And the social worker who are performing the public assistance programare consisted of 50 case: 25 case from 5 Dong in 5 cities, and 25 case from 5 Myun in 5 counties. This research reach the result that the differentiate performance of the public assistance program in rural community would be an effective device for self-support to be freed from the vicious circle of poverty.
