  • In large scale environments like airport, museum, large warehouse and department store, autonomous mobile robots will play an important role in security and surveillance tasks. Robotic security guards will give the surveyed information of large scale environments and communicate with human operator with that kind of data such as if there is an object or not and a window is open. Both for visualization of information and as human machine interface for remote control, a 3D model can give much more useful information than the typical 2D maps used in many robotic applications today. It is easier to understandable and makes user feel like being in a location of robot so that user could interact with robot more naturally in a remote circumstance and see structures such as windows and doors that cannot be seen in a 2D model. In this paper we present our simple and easy to use method to obtain a 3D textured model. For expression of reality, we need to integrate the 3D models and real scenes. Most of other cases of 3D modeling method consist of two data acquisition devices. One for getting a 3D model and another for obtaining realistic textures. In this case, the former device would be 2D laser range-finder and the latter device would be common camera. Our algorithm consists of building a measurement-based 2D metric map which is acquired by laser range-finder, texture acquisition/stitching and texture-mapping to corresponding 3D model. The algorithm is implemented with laser sensor for obtaining 2D/3D metric map and two cameras for gathering texture. Our geometric 3D model consists of planes that model the floor and walls. The geometry of the planes is extracted from the 2D metric map data. Textures for the floor and walls are generated from the images captured by two 1394 cameras which have wide Field of View angle. Image stitching and image cutting process is used to generate textured images for corresponding with a 3D model. The algorithm is applied to 2 cases which are corridor and space that has the four wall like room of building. The generated 3D map model of indoor environment is shown with VRML format and can be viewed in a web browser with a VRML plug-in. The proposed algorithm can be applied to 3D model-based remote surveillance system through WWW.

  • General aviation and air transport are two wings of the civil aviation industry. Chinese air transport is developing rapidly, and has become the world second air transport system only second to US since 2005. However, Chinese civil aviation is far behind the world average level, and cannot meet requirements of economic construction and social development. The transition and structural adjustment of Chinese economy provide the general aviation with a unprecedented broad market. The prospect of general aviation is promising and anticipated. The development of general aviation industry needs the legislative supports, and the current legislative conditions of Chinese general aviation are undoubtedly far behind the realistic requirements. Accelerating the legislation in Chinese general aviation industry requires scientific legislation concept. First, Legislation must promote development of general aviation industry. The general aviation will serves as a Chinese emerging industry that boosts domestic demand, promotes employment and expedite domestic economic development. We should, based on both the concept of promoting the industrial development of general aviation and national industrial planning, enact and rectify relative laws and regulations. And we should also straighten out the relationship between aviation security and industrial development and promote the revolution of low-altitude airspace management in an all-round way, in order to improve the utilization rate of airspace resources, classify and establish airspace, simplify examination and approval procedure and intensify operation management. In addition, what we should do is to expedite the infrastructure layout construction, guide the differentiated but coordinated development of general aviation industries in various areas, establish a united supervision mechanism of general aviation, redistrict the responsibilities of Chinese Air Control Agency and set up legislation, law enforcement and judicial systems with clarified institutions, clear positioning and classified responsibilities, so as to usher in a new era of the legislative management of Chinese general aviation industry. Second, shift the focus from regulations to both regulations and services. Considering the particularity of the general aviation, we should use American practices for reference and take into account both regulation and service functions when enacting general aviation laws. For example, we should reduce administrative licensing and market supervision, and adopt "criteria" and "approval" management systems for non-commercial and commercial aviation. Furthermore, pay attention to social benefits. Complete social rescuing mechanism through legislation. It should be clarified in legislation that general aviation operators should take the responsibilities of, and ensure to realize social benefits of environmental protection and ecological balance .Finally, rise in line with international standards. Modify Chinese regulations which is inconsistent with international ones to remove barriers to international cooperation. Specify basic legislative principles. One is the principle of coordination. Realize coordination between the civil aviation and general aviation, between military aviation and civil aviation, and among departments. Two is the principle of pertinence. The general aviation has its own rules and specialties, needing to be standardized using specialized laws and regulations. Three is the principle of efficiency. To realize time and space values of general aviation, we should complete rules in aerospace openness, general aviation airport construction, general aviation operations, and regulation enforcement. Four is the principle of security. Balance the maximum use of resources of Chinese airspace and the according potential threats to Chinese national interests and social security, and establish a complete insurance system which functions as security defense and indemnificatory measure. Establish a unified legal system. Currently, the system of Chinese general aviation laws consists of national legislation, administrative laws and regulations and civil aviation regulations (CAR). Some problems exist in three components of the system, including too general content, unclear guarantee measures, incomplete implementation details, and lacking corresponding pertinence and flexibility required by general aviation regulations, stringency of operation management and standards, and uniformity of standards. A law and regulation system, centered on laws and consisting of administrative laws regulations, industrial regulations, implementation details, industrial policies and local laws and regulations, should be established. It is suggested to modify the Civil Aviation Law to make general aviation laws complete, enact the Regulations of General Aviation Development, and accelerate the establishment, modification and abolition of Chinese general aviation laws to intensify the coordination and uniformity of regulations.

  • 무선 센서 네트워크의 다양한 연구 분야 중에서 철조망에서의 표적의 침입 탐지 및 식별에 관한 연구는 산업시설, 보안지역, 교도소, 군사지역, 공항 등 다양한 분야에서 사용된다. 현재 철조망 감시는 대부분 유선 센서 노드를 통한 유선 센서 네트워크 환경에서 이루어지고 있다. 기존의 유선 센서 네트워크는 100bps 이상의 높은 데이터 전송률을 통해 수신되는 높은 샘플링 신호를 이용하여 고속 푸리에 변환에 의한 신호의 주파수 분석 기법을 사용해 왔다. 하지만, 유선 센서 네트워크의 높은 데이터 전송률과 비교하여 무선 센서 네트워크의 센서 노드는 유선 센서 네트워크에 비해 매우 낮은 데이터 전송률을 가진다. 따라서 무선 센서 네트워크에서 수신되는 신호의 샘플링이 매우 낮고, 유선 센서 네트워크에서 사용된 고속 푸리에 변환에 의한 신호의 주파수 분석에 따른 주파수별 특징 추출을 할 수 없다. 따라서 본 논문에서는 철조망 감시를 위한 높은 데이터 전송률을 보장하는 유선 센서 네트워크에 비해 제한된 통신자원과 센서 노드의 낮은 데이터 전송률로 인해 수신되는 한정적인 신호의 정보를 이용한 무선 센서 네트워크에서 철조망의 표적 침입 탐지 및 식별을 위한 특징 추출 알고리즘을 제안한다.

  • The air waybill is supposed to be made out by the consignor. If the carrier makes it out, he is deemed, subject to proof to the contrary, to have done so on behalf of the consignor. The air waybill shall be made out in three original parts. The first part shall be marked "for the carrier", and shall be signed by the consignor. The second part shall be marked "for the consignee", it shall be signed by the consignor and by the carrier and shall accompany the goods. The third part shall be signed by the carrier and handed by him to the consignor, after the goods have been accepted. According to the original Warsow Convention article 8, the air waybill must contain 17 particulars or items. However, the Hague Protocol reduced to three the number of particulars required to appear on the air waybill. Only one item is obligatory, namely, the notice that the carriage is subject to the rules of the Warsaw Convention. The absence of the air waybill entails unlimited liability of the carrier because it deprives him of the right to avail himself of the provisions of the Warsaw Convention which exclude or limit his liability. The consignor shall be liable for all damages suffered by the carrier or any other person by reason of the irregularity, incorrectness or incompleteness of the particulars and statements in the air waybill. Although the contract of the carriage of goods by air is not a formal contract, the document of carriage is issued. The issue of air wayhill is not essential for the existence or validity of the contract, but serves merely as a means of proof. The Hague Protocol has lessened the consequences of the carrier's neglect to faithfully accomplish the required formalities. Henceforth, these formalities no longer constitute legal obligations. The air waybill is the consignment note used for the carriage of goods by air. It is often called an air consignment note and is not a document of title or transferable/negotiable instrument. It is basically a receipt for the goods for despatch and is prima facie evidence of the conditions of carriage. Each of the original parts of the air waybill has evidential value and possession of his part is a condition for the exercise by the consignor or cosignee of his rights under the contract of carriage. Oveall, it is an usage that under a documentary letter of credit, the consignee on the air waybill is the opening bank of the letter of credit, and the notify party is the importer who applied for the letter of credit. In Korea there is an usage as to process of cargo delivery in air transportation as follows: The carrier carries the cargo into the bonded area of the airport and gives both the notice of arrival of the cargo and the consignee's air waybill to the notify party who is the importer. Then the notify party obtains the Letter of Guarantee from the opening bank in exchange for reimbursing the amount of the letter of credit or tendering the security therefor to the opening bank. The notify party then presents this document to the customs authorities for the process of customs clearance. The opening bank becomes a consignee only to ensure repayment of the funds it has expended, and the only interest of the opening bank as consignee is the reimbursement of the money paid to the exporter under the documentary letter of credit. Just as the bill of lading in maritime law, the air waybill has always been considered negotiable although the Warsaw Convention does not emphasize this aspect of negotiability. However, the Hague Protocol article 4 corrected the situation by stating that "nothing in this Convention prevents the issue of a negotiable air waybill." This provision officially recognizes that the air waybill must meet the needs of the present day business circles by being a negotiable instrument. Meanwhile, Montreal Additional Protocol no. 4 has brought important changes. Registration by computer is acceptable and the parties to the contract of carriage are allowed to replace the air waybill with a receipt for the goods. In conclusion, as the Warsaw Convention has not details of provisions relating to the issuing of the negotiable air waybill, it is hoped that there should be supplement to the Warsaw Convention and establishment of international commercial usage with regard to the negotiable air waybill.

  • 본 논문은 5대 국제항공테러범죄협약, 다시 말해서 UN의 전문기구인 국제민간항공기구(ICAO)에서 제정된 1963년 도쿄협약, 1970 헤이그협약, 1971 몬트리올협약, 1988년 몬트리올 의정서 그리고 1991년 가소성폭약협약에 규정된 관할권조항의 내용과 그 문제점을 연구하였는데 국제항공테러 협약의 관할권을 연구하면서 얻은 결론을 다음과 같다. 첫째, 항공테러협약의 관할권규정에서 공통으로 발견되는 것은 어느 협약도 관할권의 우선순위를 명시하지 않고 있다는 점이다. 결국 하이재킹 된 항공기가 착륙한 국가와 항공기등록국간 관할권문제가 발생하는데 대부분의 경우 착륙국이 하이재커를 처벌하는 예가 많다. 둘째, 국제법상 전통적인 관할권이론에서 많은 이론이 제기되었던 소극적 국적주의(passive personality principle)가 국제항공테러협약의 제정 이후 각종 국제테러협약에서 점차적으로 발전되어가고 있는 경향을 볼 수 있다. 1973년의 뉴욕협약 제3조 1항, 1979년 인질협약 제5조 1항 (d) 그리고 1988년 로마협약 제6조 2항 (b)가 그 예이다. 또한 1979년 인질협약 제5조 1항 (c)와 1988년 로마협약 제6조 2항 (c)에서는 자국에게 작위 또는 부작위를 강요하기 위한 범행의 경우에도 그 대상국가가 관할권을 행사할 수 있도록하고 있다. 만일 장래에 국제항공테러협약이 개정이 될 경우에는 국제항공 테러범죄를 좀 더 효과적으로 억제하기 위하여 소극적 국적주의를 고려할 필요가 있다. 셋째, 헤이그협약이나 몬트리올협약은 범인의 국적주의를 부여하고 있지않으나 인질협약은 제5조 1항 (b)에 인질억류범의 국적국가에게 관할권을 부여하고 있다. 만일 A국가의 국민이 어떤 국가나 제3자의 작위나 부작위를 강요할 목적으로 B국가에서 인질을 억류했다면 A국가도 그자에 대한 관할권을 행사할 권리를 가진다는 것이다. 따라서 만일 국제항공테러협약이 개정이 될 때는 이 문제도 고려할 필요가 있다. 마지막으로 인질협약 제 5조 1항 (b)는 무국적자가 상주하는 국가에서 만약 그가 인질억류범죄를 행했고, 그 국가가 그렇게 하는 것이 적절하다고 고려하는 경우 그에 대하여 관할권을 행사할 권리를 부여한다. 이와 같은 목적에서 볼 때 무국적거주자를 국민과 동일하게 보고 있는데 헤이그협약이나 몬트리올협약에서는 없는 조항이다. 만일 국제항공테러협약이 개정이될 때는 이 문제도 함께 고려할 필요가 있다고 생각한다.
