This study was made on the concerns and implementation of the ICT(Inormation and Communication Technology)-utilized lesson by home economics teacher. The objective of this study is to investigate the stages of concern and the level of use of the ICT-utilized lesson by home economics teachers in Kyunggi Province through the concerns based adoption model(CBAM) and to provide assistance for ICT-utilizing lesson to be efficiently adopted to home economics. This study made selected 200 schools by random sampling among 233 middle schools which have two or more home economic teachers and 21 or more classes in Kyunggi Province which has a total of 395 middle schools and mail-surveyed on 400 home economics teachers by means of questionnaire. The stages of concern. the levels of use and the types of implementation were used as instruments in this survey. The results of this study on the stages of concern. the levels of use and the type of implementation of the ICT-utilized lesson by home economics teachers in Kyunggi Province were as following: First. the highest point of the concern of home economics teachers of ICT-utilized lesson was the stage of awareness. the second highest point was the stage of management. the 3rd stage. and the stage of information. the lst stage. Second. the highest level of implementation of ICT-utilized lesson by home economics teachers was the level of mechanical use. the 3rd stage(30.4％), which followed by the level of orientation. the 1st stage(22.5％). and the level of nonuse(16.7％). the level of rountine use. the 4th stage(13.7％) the level of integration. the 5th stage(11.8％). the level of preparation 2(3.9％). and the level of renewal. the 6th stage(1.0％) Third, information search was the most in the type of ICT-use and in the course of lesson CD-ROM was used the most.. During ICT-utilized lesson. most of teachers used computer one to two hours a week mainly in the lessons of clothing life and eating life. Home economics teachers took the most training of how to use word-processor(68.6％) during computer education. and 60 teachers(66.0％) gave positive response about the effect of computer education on teacher's learning. Finally. the biggest problem with ICT-use in the teacher's learning was the long preparation time for lesson. and problem with ICT-utilized lesson was the burden of time and effort spent to buy needed materials and to recompose the existing materials for the lesson. Therefore. so as to adopt ICT-utilized lesson efficiently into school it is needed that active promotion for the lesson should be made to teachers. training teachers to raise their ability to use computer and various kinds of software should be expanded. and school authorities' financial and administrative assistance should be given for the smooth proceeding of the lesson.

In context of e-commerce, negotiation is a procedure to help negotiate between buyer and seller by adjusting their negotiation issues such as price and in terms of payment. We used intelligent agent and mobile device to promote new framework of e-commerce. Moreover, this framework can help buyers and sellers to carry their commercial transactions effectively. In regard to that issue, we need to carry out the research of negotiation agent that can be used in e-commerce fields. In this paper, we modeled the negotiation using CSP for the performance of agent in m-commerce environment. Furthermore we implemented interface for mobile device to extract buyer's requirement and preference easily Besides that we used utility function to make a decision for various evaluation functions and suggestions that are used for evaluation of negotiation issues. A difficulty of generating offer is dependent on the number of negotiation issues and the range of the values. Therefore, if any offer has a number of negotiation issues and the range of values are wide, the search space will be exponentially expanded. There have been many studies fur solving this problem, we applied those techniques to improve the agent's ability of negotiation. For example, a contract can be accomplished by exchanging seller and buyer's offer that is generated by agent to adjust the requisite profit for each party. Finally, we show the improvement of satisfaction as the negotiation is processed.

The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

As biennale exhibitions has been expanded into all of the world since 1990s, these trends of blockbuster exhibitions have caused several problems. For instance, some major curators monopolized most global size exhibitions despite of a variety of cultural and historical backgrounds. Besides, due to a strong connection between these curators and their own artists, the young emerging artists' opportunities tend to be reduced as a result of the power game. In addition, major curators' power have influence on the exhibition style as well as on the theme itself. Some artists who did not involved that kind of huge scale exhibitions dispute that the direction of the exhibition is concentrating on the curator's interest instead of artists or viewers. Although these dissatisfactions could not portray correctly the process of organizing and managing system of a biennale exhibition, those biennale exhibitions held in recent have shown tautologic discourses without any passion and positive attitude direct to the exploitation of our society as a vanguard. In the process of comparing several kinds of biennale exhibitions, I could find that some artists who participated several biennale exhibitions at the same time did not present their creative vision, although the triumph of an exhibition was typically measured by the amount of visitors. Thus, the aim of this article is to prove that the biennale can show us new cultural discourse as well as progressive method of understanding our times. Is biennale producing the real 'global standard'? If biennale has done it, could this global standard present upto-date paradigm for the unique exhibition system? Is biennale providing an useful opportunity for the understanding and communicating of contemporary art through the recontextualization which is pronounced by the publicity of curator and organizing committee? How can we find the distinctive strategy from each biennale exhibition including Venice Biennale? Biennale, as a blockbuster exhibition, always requires a degree of hype, otherwise it would not be a special event and would not attract a big enough audience. It is the actual reason why major biennale exhibitions seem to be similar artistic events. Unfortunately, it seems that the excess of biennale exhibitions might bring about the lack of contents. In this case, the biennale syndrome would being a kind of the center of poverty, in spite of the visual splendor. After all, following the global standard may not be a matter of great importance now. What really matters is how each biennale exhibition which started under the different conditions can search their own identity.

Environmental value is essential to the survival and development of humans. Environmental value and its importance are being emphasized, and related disputes are being expanded. The concept of green logistics is understood to be the same as that of the environment. As a way to preserve nature and engage in sustainable development, green logistics includes all logistical activities for protecting nature and minimizing or reducing behaviors that harm the environment for all processes, including using and reusing products and abolishing the search for resources by final users. All areas of human activity, such as the political, economic, social, and cultural sectors, strive to protect and preserve the environment and nature. In particular, the preservation of the environment shall be stressed in the economic activities that produce various products and expand the value added, and similarly for the social aspects. Green (environment) logistics aims to protect the environment and expand the prevention of environmental destruction and minimization on Earth. Some important cases and experiences that were introduced and applied in major countries are summarized. This research reviewed previous studies and the concepts of green logistics, including at ports, which represent a key sector of logistical activities. In this paper, air and water pollution at Incheon Port were investigated, and alternatives and system figures related to improving environmental logistics regarding three dimensions-country, company, and civil society-are recommended.

Recently, drone applications have been expanded not only in the military and security fields but also in daily life such as commercial and sports, and there is also a growing interest in using drone for private security work. This study focuses on the discussion on the use of drones in private security, drones regulation in the related laws such as the Private Security Act and the Aviation Safety Law, and major issues in accepting the Private Security Act. First, it focuses on the scope of private security work as defined by the Private Security Act, focusing on the use of drones as surveillance, information gathering, guidance and warning services, evacuation services, search and related material transport services, respectively. Second, the related laws for the use of drones in private security work include the Private Security Act and the Aviation Safety Act. However, the Private Security Act does not prescribe the current drones and the use of drones is regulated by Aviation Safety Act. Third, it is necessary to adjust the qualifications and authority range of security guards in the Private Security Act, to accept the drones as a type of security equipment, and to consider how countermeasures against threat types using drones should be accepted in the Private Security Act.

The following results could be obtained from the research on awareness and satisfaction of the tourists who joined the program 'A Journey in Search of King Mu's Road'. With regard to awareness of the site tour program, tourists replied that they participated in the program mainly because of their interest in education for their children. They expressed great needs for the municipal government office to maintain walkways, signboards and guide maps as well as to reinforce safety facilities as a measure to increase satisfaction with the site tour on the part of visitors and tourists. In terms of satisfaction with operation and management of the site tour program, the contents of the program were highly appreciated while it turned out necessary to rediscover garden culture resources and to develop and operate an expanded internal tour course for tourists to look around inside the relics by utilizing the recently excavated Baekje historical resources. As a consequence, it might be expected possible to experience and educate the local history and garden culture thanks to the historical culture and environmental values that have been preserved in the Baekje cultural circles. Moreover, the importance of walking trips will be recognized for its effects to allow those who get tired from daily life to come into contact with nature, practice self-reflection and care for their health as well.

The purpose of this study is to derive a curriculum environment for operating various student-centered teaching and learning methods, and the following results were derived: First, most of the lectures, discussions and consultations, data search, report preparation, presentation, work exhibition, and others were commonly derived, regardless of the types of long-term and short-term project classes for each subject. In particular, the necessity of operating various classes at the same time was suggested, indicating the need for an integrated teaching and learning operation environment in the unit subject class. Second, considering that practical classes are linked concurrently to lectures and discussion classes to conduct one subject class, it is necessary to switch to a specialized curriculum system that allows various classes such as lectures to be carried out at the same time. Third, as a result of grasping the appropriateness of the space size of the subject class for realizing different class types in the future, it can be seen that the space size of the practice room, including the space for practice and the area for exhibition, should be expanded. Based on the research results, the spatial environment for the operation of future teaching and learning classes is based on the public curriculum classroom system, and whether professional curriculum classes, such as lecture rooms and discussion and presentation rooms, are secured according to the number of students.

In recent years, many Internet giants have begun providing their own content services, which attract online users by offering personalized services based on artificial intelligence technologies. This study investigates the role of two firms' content services within the firms' online service network. We examine the role of Naver Webtoon, which can be characterized as a professional-generated content, within Naver's service portfolio, and that of Google YouTube, which can be characterized as a user-generated content, within Google's service portfolio. Using survey data on viewers' use of the two services, we analyze a valued directed service network, where a node denotes an online service and a relationship between two nodes denotes a sequential use of two services. We found that both Webtoon and YouTube show higher out-degree centrality than in-degree centrality, which implies these content services are more likely to be starting services rather than arriving services within the firms' interactive network. The gap between the out-degree and in-degree centrality of YouTube is much smaller than that of Webtoon. The high centrality of YouTube, a user-generated content service, within the Google service network shows that YouTube's initial role of providing specific-content videos (e.g., entertainment) has expanded into a general search service for users.

By the middle of 2018 there are signs of China's entry into a new period of development, characterized by a change in the old model: "market reforms-inner-party democratization - moderate foreign policy" to another: "market reforms - Xi Jinping personality cult - offensive foreign policy." This model contains the risks of arising of the contradiction between economic freedom and political-ideological rigidity which can lead to destabilization of the political life. However, in the current positive economic dynamics, these risks may come out, rather, in the medium and long term. Today, the political situation in China remains stable - despite growing dissatisfaction in scientific expert and educational circles due to increased control over the intellectual sphere by the authorities. The need for a new redistribution of power between central and provincial authorities could potentially disrupt political stability in the medium term, but, at the moment, is not a critical negative factor. The economic situation is positive-stable. Forecasts indicate a possible increase in China's GDP in 2018 at 6.5%. At the same time, there are negative expectations in connection with the Sino-US and potentially Sino-European "trade war". In the Chinese foreign policy, as a response to Western pressure, China increasingly uses the Russian direction of its diplomacy in the expanded version of Russia + SCO. The nuance here is seen in China's adjusted approach to the SCO: first of all, not as a mechanism for cooperation with Russia, but as an organization that allows using Russia's potential for pressure on the US in the Sino-US strategic rivalry. In the second half of 2018, the Chinese economy will continue to develop steadily, albeit with unresolved traditional problems (debts of provinces and state-owned enterprises, ineffective state sector, risks on the financial and real estate market). In politics, discontent with the cult of Xi will accumulate, but without real threats to its power. Weakening in economic opposition between China and the United States is possible due to Beijing's search for compromises on tariffs, intellectual property, trade deficit. To find such trade-offs, Xi will use the so-called. "Personal diplomacy" of direct contacts with Trump.
