The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

The ubiquitous city construction act worked as an institutional basis for the U-City projects which were actively driven in the new urban areas until 2010. However, the country's urban policies which were recently changed focusing on revitalization of the existing towns and urban regeneration led to the increased demand for revision of the u-City law with a strong character of procedural law mainly for the new urban areas. Therefore, this study, taking into account the changes of the country's urban policies and the conditions related to u-City, established the direction of revision on the u-City law as the diversification of the u-City projects, reinforcement of u-City management operation and the supports for the u-City projects, and presented the consequent action plans. This study aims to review the problems with the current u-City law and the improvement plan from the practical point of view for reflecting the country's urban policy flow and demand. It is expected that the result of this study will be able to be utilized as a basic material for supporting the continuous development and expansion of u-City by law and system.

The effect of immune activation by Echinacea purpurea was investigated by measuring total immunoglobulin (Ig) G, IgM. and the radioprotective effect of immune activation by Echinacea purpurea was investigated by measuring T lymphocyte subsets in the peripheral blood of mice following whole body irradiation. Echinacea purpurea activated macrophages to stimulate $IFN-{\gamma}$ production in association with the secondary activation of T lymphocytes, resulting in a decrease in IgG and IgM production. Cytokines released from macrophages in mouse peripheral blood after Echinacea purpurea administration activated helper T cells to proliferate. In addition, activated macrophages in association with the secondary T lymphocyte activation increased $IFN-{\gamma}$ production and stimulated proliferation of cytotoxic T cells and suppressor T cells, indicating the activation of cell-mediated immune responses.

It is not entirely new tendency now that museum have to become 'participation and working activity style' in 21st century. A lot of museums are changed fast to that visitors participate and work actively in museum program recently in Korea. Cheongju city is building various museums which have interesting themes contributed precious inheritances and collections belong to citizens. And Cheongju city is pushing ahead long-term target which is Ecomuseum City Cheongju with citizen is progressing for cultural city continuously. Also to become public museums and facilities which visitors want to come again, Cheongju city is trying to secure various experience space and facilities to keep in step in trend that visitors take part in and work actively in museum program. In an area, there are various cultural, historical, natural and industrial heritages that express relation of human and environment. In meaning that do function of antenna of sending culture which understanding, studying, informing these regional inheritances and promoting activity, in Ecomuseum, those are called "satellite" included not only regional preserved inheritances but also various theme museums which have mutual cooperative function. Satellite(or antenna) is very important element composing Ecomuseum. So I want to provide that is "Exhibition Working-Activity Satellite" that are places having experience space or facilities which visitors can work actively there like that. Such study for Ecomuseum and Exhibition Working-Activity Satellite can be promoted Ecomuseum City which is city for learning lifetime with citizens.

Administrative city has been developed step by step aiming to being a public transport-oriented new city. In spite of its primary goal, administrative city is dominated by car-oriented tansportaion system because the supply of public transportation has not been adequately and timely performed. In this study, we investigate the current situation related to (public) transportation use in administrative city. Also, we examine the issues of traffic system through a survey on residents' consciousness about public transportation use. Additionally, the analysis of demand elasticity according to the change of the conditions of using public transportation and passenger car is conducted for passenger car users. As a result, it is analyzed that as the neighborhood is more stabilized after the completion of development the resistance to the abandonment of passenger car is higher when the tide demand control method is introduced. Therefore, it is concluded that pre-emptive public transportation supply and the management of car demand management are necessary for the activation of public transportation in Administrative city.

This study starts from the architectural and urban interest to integrate the daily life and behavior of residents in the city of Seongnam and to sustain the community. A fixed abode is something that can not be separated from the place and should be approached from a comprehensive perspective reflecting the physical and social conditions of the region. Although residential neighborhoods have a residential walking range, which has a steep slope, it has been formed in the suburbs of the residential area where commercial facilities are activated organically. The humanities and social organizations of the residents are integrated with the physical space and act as constituent factors of major cities. This is an attempt to suggest improvement and activation of existing cities based on their daily lives, rather than destroying cities and creating new ones. Also, it is proposed to 'Neighborhood Street' as an indicator of a uniform urban renewal plan for existing urban regeneration projects. Based on the definition of the city of living in the city, the center of the city will be located in the center of the city, and it will be the center of the city's bustling streets.
