In this paper, we present the strategy of object search for distributed autonomous robotic systems (DARS). The DARS are the systems that consist of multiple autonomous robotic agents to whom required functions are distributed. For instance, the agents should recognize their surrounding at where they are located and generate some rules to act upon by themselves. In this paper, we introduce the strategy for multiple DARS robots to search a hidden object at the unknown area. First, we present an area-based action making process to determine the direction change of the robots during their maneuvers. Second, we also present Q learning adaptation to enhance the area-based action making process. Third, we introduce the coordinate system to represent a robot's current location. In the end of this paper, we show experimental results using hexagon-based Q learning to find the hidden object.

This paper describes an efficient global cell (module) placement strategy called HALO (Hierarchical Alternating Linear Ordering)which generates global 2-D placement of circuit modules by hierarchical application of linear ordering in alternating direction. We tried, in principle, to explain why HALO should perform better than other typical, somehat successful, analytical approaches such as min-cut, force-directed relaxation(FDR)or its likes. We have implemented HALO as a program for standard cell placement. Experimental results on two benchmark circuits, primary and primary 2 consisting of 752 and 2907 cells, respectively have shown a decrease of half-perimeter routing length by 7% and 24%, respectively compared to the best available results obtained so far. Total CPU time including the following detailed placement was less than half of the earlier work.

Recently Korean firms are increasingly interested in internet business while the number of internet users reaches more than 10 million in Korea. As e-commerce develop rapidly, customer-oriented marketing for online business becomes very important. The issues of how to achieve customer satisfaction in Internet business and how to plan a marketing strategy for online business faced managers of Internet business. Customer-satisfaction is much more important for internet business than for traditional offline 'brick and mortars'. Marketing activities need to be carried out on customer-orientation to achieve high level of customer satisfaction. This paper will discuss how to develop customer-oriented marketing for online business. It will specifically study the characteristics and success factors of internet business, differences between online marketing-mix strategy for e-business in view of customer-orientation. Finally it will suggest a future direction for online fashion business by applying the customer-oriented marketing of Internet business to the fashion business.

Marketing activities need to be carried out on customer-orientation to achieve high level of customer satisfaction. This paper will discuss how to develop customer-oriented marketing for online business. It will specifically study the characteristics and success factors of Internet business, differences between online marketing and traditional marketing, selection of target market, and online marketing-mix strategy for e-business in view of customer-orientation. Finally it will suggest a future direction for online fashion business by applying the customer-oriented marketing of Internet business to the fashion business.

Construction projects that should be under the construction supervision regulation were decreased in 2008 and new supervision projects in 2010 were significantly reduced by 60% comparing to the ones as of 2009. On the contrast, the volume of world construction projects including Middle·South Asia and Africa is forecasting to be increased by 46% in 2018. However, although the needs of oversea expansion of domestic construction supervision firms are appeared more and more, their preparations to the strategically important areas in the world are insufficient. Thus, this paper aims to suggest directions of strategics and plans for domestic construction supervision industry to expand the market to the world through questionnaire surveys and expert investigation.

This research proposes the use of a patent analysis methodology that can suggest promising technology in the ICT sector at the micro-level. This approach identifies core patents from the technology field, groups them as research frontiers (RFs), and develops a visualized network based on the citing relationships to monitor the relationship among RFs. In addition, it calculates a "promising index" based on the growth potential, impact, and marketability of patents to ultimately derive promising RFs. To illustrate the proposed approach, this research presents analysis results for a chosen area, which is the user interface and user experience (UI/UX) technology field. By proposing promising technological fields at the micro-level, the proposed methodology will serve as a useful decision-making support tool in selecting R&D projects, technology planning, and determining technology policy direction.

The professionalization of unauthoritative medical service has been progressed over time, transforming based on the motive, strategy and the social environment of the medical society. Osteopathology and Chiropractic have been professionalized in totally different steps, even though their basic philosophy and the theory are very much the same. The historical suggestions of these osteolopathology and chiropractic in England and United States is that the economical conditions and the point of view that society has on the relationship between human and medicines affect decisively on the social transformation of the community. Observations through these examples will provide many informations as a source on political measures for a medical society to decide for its future direction.

2005, National railway was converted from government enterprise form to public corporation form. Korail is facing in necessity to equip new manpower operating system to achieve public enterprise's part and two purposes called profit creation according to conversion to construction system. Accordingly, railway construction work began services for formation diagnostic and job analysis to construct management formation of new paradigm, personnel management course manpower operation system of the job value priority. This dissertation is research for direction establishment of human resource management(HRM) of railway construction work. Examined problem of current personnel management system with trend of HRM paradigm for this. And presented various strategy to construct greeting executive system of job putting first in person putting first and strengthens formation capacity.

Variation of decision variables for optimal remediation using the pump-and-treat method is examined to estimate the effect of the degree of concentration constraint. Simulation-optimization method using genetic algorithm is applied to minimize the total pumping volume. In total volume minimization strategy, the remediation time increases rapidly prior to significant increase in pumping rates. When the concentration constraint is set severer, the more wells are required and the well on the down-gradient direction from the plume hot-spot gives more efficient remediation performance than that on the hot-spot position. These results show that the more profitable strategy for remediation can be achieved by increasing the required remediation time than raising the pumping rate until the time reaches a certain limitation level. So, the remediation time has to be considered as one of the essential decision variables fer optimal remediation design.

Korean food industry has been developed while it receives footlights as the most encouraging industry and composing one axis of food industry under various marketing activities and severe competitions. The purpose of this study was to understand customer's reason to use bakery, extract important factor, systematically analyze and suggest the direction of bakery industry through study on the character of bakery-user. The researcher Modified the Questionnaire developed by Yoon, YH(2000) & Kim, SE(2002). The major findings obtained from this study were as follows. First, on factors of confidence and propriety, price and communication with consumers, product and service, and service response, there was a high difference between male and female. Second, on factors of accessibility & product and service, there was a high difference among disparity of age. Third, on item of confidence and propriety, there was a high difference among customers' residing styles. Fourth, in relation to income level, there was statistically no difference.
