Through the increment of requirement for EC(Electronic Commerce) oriented communication services, security multicast communications is becoming more important. However, multicast to EC environment is much different from unicast concept most network security protocols. On the network security, using mandatory access control of multilevel architecture which assigns a specific meaning to each subject, so we accomplish access control. In this way, access control security based on the information security level is proposed. A security protocol based on the architecture proposed in this paper would be utilized in security multicast communications, group key management service and leveled security service through multilevel EC security policy, Also we discuss and propose the security level scaleability and key management method on the network.

There have been many research papers and practical implementations on the various EC(Electronic Commerce) aspects such as merchant system, security, payment gateway, legal and policy issues. However, it is very hard to find the systematic approaches and business process models from the viewpoint of the company willing to start B2C(Business-To-Customer) EC. Therefore, we develop business process models for the planning, systems analysis and design, implementation, and operation of internet shopping mall to suggest a guideline and reference model for the realization of successful B2C EC.

Attempts have also been made to locate security in the so-called 'policingdivision of labour' In order to understand this, it is necessary to identify some of the links which exist between public police organizations and the private security sector. Such links can be divided into six types : 1) Interpersonal links, 2) Joint operations, 3) Exchange of services, 4) Granting of special powers, 5) Public bodies hiring private personnel, 6) New organizational. Van Reenen provides a useful outline of the different dimensions of future Glibalization of policing. Developments, he suggests, are likely to proceed in four directions : 1) Co-operation : at this level, the nature and powers of national police systems are not required to change, co-operation occurring between self-standing forces. 2) Horizontal integration : this arises when officers obtain authority to operate in another country, or where government officials from one country get authority over the police in another country. 3) Vertical integration : this exists when a police organization is created which can operate within the area of the EC as a whole. 4) Competition : the internationalization of policing in Europe presents itself, more and more, as a market in which different policing systems trade their products.

본 논문에서는 탑승거부와 관련한 EC 261/2004 규칙의 규정 및 그에 관한 판결들을 검토해 보았다. 항공여객운송 분쟁과 관련하여 빈번히 발생하는 탑승거부는 그 의미가 EC 261/2004 규칙상으로 그리 명확한 것은 아니지만, 앞서 살펴본 EU 판결들에서 어느 정도 그 범위에 관한 해석기준을 제시되어 있다. 일반적으로 탑승거부는 초과예약으로 인해 발생한 경우를 상정하는 것이 기존의 관점이었지만, 일련의 EU 판례에 따라 EC 261/2004 규칙상의 탑승거부에 다양한 경우의 탑승거부 사례들이 포함되게 되었다. 즉, 탑승거부의 개념과 범위가 포괄적으로 확대되고 보다 적극적인 항공소비자 보호가 실현될 수 있을 것으로 보인다. 이와 같은 관점에서 논문의 결론으로서 몇 가지 시사점들을 제시해 보고자 한다. 첫째, EC 261/2004 규칙상 탑승거부의 개념에는 초과예약으로 인해 발생한 탑승거부만이 아닌 다양한 경우의 탑승거부 사례들이 포함될 필요가 있다. 이는 EC규칙이 항공소비자의 권리보호를 제정목적으로 하고 있다는 점, 초과예약에 의한 탑승거부만을 규칙에서 의미하는 탑승거부만으로 볼 경우 항공여객의 권리구제가 훼손될 수 있다는 점, EC항공여객보상규칙 제2조 j호의 문면상 초과예약에 의한 탑승거부만으로는 결코 한정시킬 수 없다는 점 등의 이유 때문이다. 둘째, 탑승거부와 관련하여, 항공사의 초과예약도 없었고 항공사의 별도 과실이나 귀책사유도 발견되지 않은 경우, 여기서 그 원인의 본질에 EC 261/2004 규칙상의 특별한 사정이 존재하고 있는 경우에는 그 특별한 사정의 판단을 적절하게 고려할 필요가 있다. Finnair 판결에서는 파업과 같은 특별한 사정으로 인해 결항이 발생하였고, 연결항공편의 일정 조정은 불가피한 것이었음에도, 그러한 과정에서 탑승거부가 발생하였다. 여기서 항공운송인의 과실 내지는 귀책을 명확하게 찾을 수 없었다는 점이 중요하다. 법원은 이 경우에도 운송인의 보상책임을 인정하고 있는데, 결항의 원인이 항공운송인이 모든 합리적인 조치를 취했어도 피할 수 없었던 파업에 의해 발생한 것이라면 특별한 사정의 판단이 적용되어야 할 필요성이 있다. 셋째, EC 261/2004 규칙상 탑승거부와 결항의 경우에는 여객에게 금전보상이 이루어지고, 항공지연의 경우에는 금전보상이 아니라 대체항공편과 같은 항공사의 적절한 지원책만이 제공되고 있다. 만약 제1항공편과 제2항공편으로 연결항공에 의한 환승이 포함되어 있는 항공일정이 있을 때, 천재지변에 의해 제1항공편이 지연되었다. 지연은 되었으나 가까스로 여객은 제2항공편에 탑승게이트에 도착하였다. 이 경우의 문제는 어떻게 해결하여야 하는지가 문제이다. 제1항공편의 지연은 천재지변으로 특별한 사정에 해당하여 항공사는 면책을 주장할 수 있지만, 제2항공편의 탑승거부도 그렇게 주장할 수 있는지 명확하지 않다. Finnair 판결의 취지를 따르면, 제2항공편의 탑승거부에 대한 항공운송인의 보상의무가 가능할 수 있는데, 항공운송인이 아무런 과실과 귀책이 없는 경우에도 보상이 가능한 것인지 의문이다. 또한 동일한 원인으로 발생한 지연과 탑승거부에 대해 이처럼 다른 보상기준이 적용될 수 있는지도 문제이다. 향후의 EU사법재판소 판례가 EC 261/2004 규칙의 해석과 적용상 이러한 문제를 어떠한 방식으로 접근할 것인지 기대된다.

To develop an blue tourism website(BTW) for electronic commerce(EC), information requirements of BTW are defined firstly. We defined information requirements of BTW from two aspects, i.e., front office and back office. Information requirements for front office were derived by consumer purchasing decision process. And information requirements for back office were derived by tourism value chain. Total 29 functions are identified as critical EC related functions of BTW. Among them, 25 functions were investigated into BTW. BTWs were searched by search engines - Yahoo and Empas - to Korean websites. There are 12 specialized BTWs, except one cyber museum website. For 12 websites, 25 functions were probed. By the results, in need recognition stage of blue tourism, only weather information was provided in most websites. In information search stage of blue tourism, package recommendation and various contents were provided in most websites. In consumption stage of blue tourism, traffic information were provided in most websites. And in after - sales service stage of blue tourism, bulletin board function was implemented in most websites. The rest of the functions were scarcely implemented. On the whole, it was concluded that most EC related functions of BTW in Korea were not implemented properly. To improve the status quo, it is expected in the dimension of individual website, that marketing planning, customized service, intelligent service, reinforcing purchasing assistance functions, customer relationship management, and escrow service etc. need to be implemented. And it is expected in the dimension of blue tourism industry, that standardizing product catalog, security assistance policy, information sharing by industrial database, finding referral model of BTW, elevating information mind, revising related laws etc. are needed.

대부분의 안전한 운영체제는 주체와 객체에 보안 등급을 부여하여 운영하는 다중등급 정책(MLP: Multi-Level Policy)을 수용하고 있으며, BLP 모델은 이 정책을 표현하는 검증된 대표적인 모델이다. 하지만 이러한 다중 등급 보안 운영체제들은 접근 주체인 프로세스가 접근 객체로서 존재하는 등급화 된 프로그램을 실행 시 새로운 프로세스를 위한 보안 등급을 부여해야 하는데, 접근 주체와 접근 객체의 보안 등급이 다를 경우 보안 등급 결정 문제가 발생하며 정보보호의 목적에 위배되는 결과가 발생한다. 이에 본 논문에서는 위에 언급된 문제를 해결할 수 있는 방안을 BLP 모델 측면에서 고찰한다.

In a seminal judgment of November 2002 (Case C-476/98) relating to the compatibility with Community laws of the 'nationality clause' in the 1996 amending protocol to the 1955 U.S.-German Air Services Agreement, the European Court of Justice(ECJ) decided that the provision constituted a measure of an intrinsically discriminatory nature and was thus contrary to the principle of national treatment established under Art. 52 of the EC Treaty. The Court, rejecting bluntly the German government' submissions relying on public policy grounds(Art. 56, EC Treaty), seemed content to declare and rule that the protocol provision requiring a contracting state party to ensure substantial ownership and effective control by its nationals of its designated airlines had violated the requirement of national treatment reserved for other Community Members under the salient Treaty provision. The German counterclaims against the Commission, although tantalizing not only from the perusal of the judgment but from the perspective of international air law, were nonetheless invariably correct and to the point. For such a clause has been justified to defend the 'fundamental interests of society from a serious threat' that may result from granting operating licenses or necessary technical authorizations to an airline company of a third country. Indeed, the nationality clause has been inserted in most of the liberal bilaterals to allow the parties to enforce their own national laws and regulations governing aviation safety and security. Such a clause is not targeted as a device for discriminating against the nationals of any third State. It simply acts as the minimum legal safeguards against aviation risk empowering a party to take legal control of the designated airlines. Unfortunately, the German call for the review of such a foremost objective and rationale underlying the nationality clause landed on the deaf ears of the Court which appeared quite happy not to take stock of the potential implications and consequences in its absence and of the legality under international law of the 'national treatment' requirement of Community laws. Again, while US law limits foreign shareholders to 24.9% of its airlines, the European Community limits non-EC ownership to 49%, precluding any ownership and effective control by foreign nationals of EC airlines, let alone any foreign takeover and merger. Given this, it appears inconsistent and unreasonable for the EC to demand, $vis-{\grave{a}}-vis$ a non-EC third State, national treatment for all of its Member States. The ECJ's decision was also wrongly premised on the precedence of Community laws over international law, and in particular, international air law. It simply is another form of asserting and enforcing de facto extraterritorial application of Community laws to a non-EC third country. Again, the ruling runs counter to an established rule of international law that a treaty does not, as a matter of principle, create either obligations or rights for a third State. Aside from the legal problems, the 'national treatment' may not be economically justified either, in light of the free-rider problem and resulting externalities or inefficiency. On the strength of international law and economics, therefore, airlines of Community Members other than the designated German and U.S. air carriers are neither eligible for traffic rights, nor entitled to operate between or 'free-ride' on the U.S. and German points. All in all and in all fairness, the European Court's ruling was nothing short of an outright condemnation of established rules and principles of international law and international air law. Nor is the national treatment requirement justified by the economic logic of deregulation or liberalization of aviation markets. Nor has the requirement much to do with fair competition and increased efficiency.

Background: Within the framework of the new Saudi Vision 2030, the education system is keen on developing Early Childhood (EC) curricula to meet the needs of children from diverse cultural and linguistic backgrounds, in addition to preparing teachers to be the main driving forces in this field. To achieve these strategic goals, the professional development of teachers has taken the lead in terms of their continuous professional achievements. Purpose: The recent study tended to explore the promotion of Cultural and Linguistic Competence (CLC) of teachers in preschool institutions in different sectors in the Kingdom of Saudi Arabia (KSA) include public, private and international. Method: In the current study, (n=300) of preschool female teachers, who had experience teaching children from diverse language and cultural backgrounds, participated voluntarily by filling out the exploratory questionnaire. It was designed on a five-point Likert scale. The credibility of the scale and the validity of the questionnaire were ascertained, and the content for which it was designed verified in terms of the purposes of the current investigation. Results: The results revealed that preschool female teachers in the private preschool settings have a higher level of CLC compared to those who were teaching in public and international preschools in KSA. In the private sector, preschool female teachers showed create abilities to provide culturally responsive environments for diverse students, applying various communication styles, and showing proper attitudes and values toward diversity. Implication: The current study provided key implications for policy makers regarding the promotion of CLC for all teachers, particularly preschool in government settings in KSA. It contributed to revealing the cultural awareness of preschool teachers' values and attitudes toward diversity.
