This study is in the purpose for the revitalization of traditional market as comparing to the relevancy between the central characteristics of a floating population going around for buying something or eating food and lots of small-sized businesses comprising of the commercial districts. The several traditional markets such as Cheonan station, Dujeong-dong, Sinbu-dong in Cheon-An city has been investigated repeatedly almost every two or three years by the Small Enterprise development Agency(SEDA) since 2001. By analyzing the raw data of those commercial districts made by SEDA, we can calculate the number of firms andthe ratio of business type of each commercial districts. In this research, the type of each business is classified into four groups such as restaurant, service, retail and the rest. Moreover, the central character of the floating population is derived from the raw data, which means the customer information about sex, age structure or the most populous time zones. From these characteristics, one commercial districts has his own specific features distinguishing from the others. The most important differences of past researches are firstly the dynamic viewpoint rather than a static one. Secondly it suggests that the relation between the central characteristics of districts and the floating population would exist. Lastly, it suggests that the interaction between both of them have a significant effect on the growth or decline of the districts and the rates of business type, other adjacent commercial districts as well. Eventually, this study provides several meaningful points for the revitalization of commercial districts to government or stakeholder such as management organization, business owners and new starter etc.

In general, commercial franchisors prefer franchisees with high entrepreneurship and business capability. However, these entrepreneurial franchisees with high capability tend to depend less on franchisors. Although franchisees with less entrepreneurship and low capability need intensive care from franchisors, some of them result in business failure due to improper supports from incapable franchisors. This paper suggests several propositions regarding social franchising's role in supporting the low-income urban people on the premise that social franchising or micro-franchising provides implications for franchisor strategic orientations for franchisees with little capital. Through literature review about social franchising and micro franchising, some implications are drawn. Many social enterprises use franchising to get growth and sustainability, because franchising allow social enterprise to expand its scale and to achieve economies of scale despite of its non-commercial and social purpose. And continuous support and training undertake the most important role to achieve its social purpose. In commercial franchising, especially small business format franchising sector, franchisor have to consider not only commercial purpose but also social responsibility because of low capability and less entrepreneurship of franchisee. If franchisor pursue only own profit, this can increase the conflict and franchise system failure. So far many franchisors are concerned with own profit and external growth. But it is necessary to consider symbiotic relationship, social responsibility and sustainability more for the sake of desirable industrial growth in the future.

When a metal oxide field effect transistor (MOSFET) is exposed to ionizing radiation, electron/hole pairs are generated in its oxide layer. The slow moving holes of them are trapped in the oxide layer of p-MOSFET and appear as extra charges that change the characteristics of the transistor. The radiation-induced charges directly impact the threshold (turn-on) voltage of the transistor. This paper describes the use of the radiation-induced threshold voltage change as an accumulated radiation dose monitoring sensor. Two kinds of commercial p-type MOSFETS were tested in a Co-60 gamma irradiation facility to see their capabilities as a radiation dosimeter. We found that the transistors showed good linearity in their threshold voltage shift characteristics with radiation dose. The results demonstrate the potential use of commercial p-MOSFETS as inexpensive radiation sensors for the first time.

We are now entering the era of Commercial Space Transportation with the rapid commercialization of space. Commercial Space Tourism will be realized first of all in the commercial space transportation and the spacecraft is developing for it led by private enterprise such as Virgin Galatic and XCOR Aerospace. The spacecraft for space tourism is developed as Reusable Launch Vehicle(RLV). RLV Spaceship I & II manufactured by the Scaled Composites for Virgin Galatic had completed experimental flight successfully and is going to put to the operation for space travel around the year 2012. In our country, Yecheon Astro-Space Center located in Yecheon, Kyungbuk Province, signed a binding-MOU with XCOR Aerospace and going to start space travel in the year 2013 with the spacecraft LYNX MARK-II. Thus, now space travel has become a reality to us. But it is also reality that there's no study by legal basis preparing for the space tourism domestically and internationally. In this regards, this thesis dealt with legal issues related to space tourism. These are as follows : (1) the applicabe law issue that is which law between air law and space law will apply, (2) the status of space tourist issue that is space tourist can be considered as personnel of a spacecraft and/or space flight participant and has the duty to obey the order of the captain of spacecraft, (3) the responsibility of the government for the non-governmental entities such as private enterprise which involved in space tourism in case space accident occurs during the space travel, (4) license permit and supervision issue by the government (In this point, for activating the market of the space tourism, I think it is essential to guarantee the safety of the spacecraft by the government authority, though U. S. government declared that it has not certified the launch vehicle as safe for carrying crew or space flight participants), (5) registration issue, (6) space insurance issue. For all the issues mentioned above, I have studied the existing international treaties and several country's domestic law to the space by referring U.S's Commercial Space Launch Amendment Act of 2004 and New IGA of 1998 and concluded that uniform legal regime to govern these issues should be established domestically and internationally in the near future.

The web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. This Paper proposes an active web server which can facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such a goal, the active web server manages dependency relationships between shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefullness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System (ODBMS) called OBJECTSTORE using the C＋＋ programming language.

This paper investigates the importance and satisfaction levels according to factors on commercial Enterprise Resource Planning(ERP) packages in the view of end users when the ERP system is employed especially in SMEs. Considering the characteristics and functions of ERP packages, five factors (vendor, technology, function, A/S, price) are obtained based on the literature review. The proposed procedure consists of finding importance factors and satisfaction levels which support the selection of ERP packages for a certain SME. When a company tries to implement the ERP system, the findings in this paper suggest which ERP package is suitable for its own business environment.

This paper presents a multi-scale hybrid simulation for the design of a catalytic multi-tubular reactor with high performance. The multi-tubular reactor consists of shell and a large number of tubes in which various catalytic chemical reactions occur. To consider fluid dynamics in the shell-side and kinetics in the tube-side at the same time, commercial CFD package and process simulation tool are coupled. This hybrid approach allowed us to predict many kinds of meaningful results such as tube center temperature profile, heat transfer coefficients on the tube wall, temperature rise of cooling medium, pressure drop through shell and tube side, concentration profile of each chemical species along the tube, and so on., and to achieve the optimal reactor design.

The general commercial printing meets the customer's diverse demand by using spot color besides process four color. Especially, by using spot color for printing the enterprise's logo or specific color, we can see the effect of printing is getting better. The objective of this study was to examine the quality of spot color reproduction with Inkjet for 2 types of paper and Dye sublimation in ICC-based color management system. ICC profiles were generated for each device using ECI 2002 visual target and evaluated for the accuracy of each printer's color profile. The test chart consisting of Pantone color 1140 was selected to test the quality of spot color reproduction.

If we build new building after demolition of commercial building that is located in the downtown, it will be caused a social and environmental problem as wasting of resources and generating of waste. In this study, I investigated about remodel ins, this conclusion is given below. 1. Reconstruction cost is 2.1 times, and construction period is 1.4 times as much remodeling. So remodeling has an advantage. 2. For repairing and reinforcing timeworn building, we reinforced it as using carbon fiber sheet (girder, slab) and injecting method steel plate bonding Also, we tried to maintain efficiency of new building as using epoxy to protect concrete crack. 3. In the side of waste products and cost, remodeling has much more advantage than reconstruct. But demolition used construction period much. Because it had to be reused as repairing and reinforcing. And there was no difference between remodeling cost and reconstruct cost. If we develop research with enterprise.university.laboratory to exploit material and equipment and to train specialized engineer who will has a capacity to know construct repair and reinforce, it can be attribute to prevail remodeling in new construct market.
