A new roof edge detection method based on multi level scales of wavelet function is proposed in this paper roof edge and its direction are obtained in this new methods at one time. Besides. scale characteristics of detecting roof edge is analyzed. And a few new methods on fingerprint image pre-processing are described. A method segmenting foreground/background of fingerprint images is proposed, in which Prior estimation of direction field is not required any more. A segmentation method based on multi-scale roof edges is implemented. and the valid scale range of the method is defined. too. And the method is used to segment ridges and valleys in fingerprint images simultaneously The exact direction fields made up of the direction of each point in ridges can be obtained when detecting ridges exactly based on the roof edge detector, in comparison with the traditional coarse estimation of direction fields. Obviously. it will establish a solid foundation for the sequent fingerprint identification.

This research is the comparative analysis of Jim Hall's master work "Careful" and "Waltz New" who is the most influential guitar player of the present day. I tried to analysis musical inclination and direction comparison with contemporary musicians in this study. Jim Hall wasn't the person who did satisfy with only playing guitar as a famous artist but trying to research and create a new thing continuously with this his music. I am considering that his music has been great implications for contemporary direction.

With regard to the new town developments which have supplied lots of houses in a short period of time in Korea this study aims to evaluation and finding out problems of the developments finally to suggest the direction. A new town's competitiveness model set in the previous paper takes a role of research frame to recognize the problems and to show the direction. The model explains that new town's competitiveness is composed of 4 factors; Self-sufficiency, Innovativenss, Identity and Sustainability. Problems of the developments are as follows; incongruity of spatial structure especially in the capital region, deficiency of self-sufficiency resulted from single-use development, restriction on mixed development by a number of regulations in capital region, low business value, grand scale of land compensation, house oriented planning guidance, unfair share of infrastructure fee, and physical structure depending mainly on fossil energy. Based on this recognition this study conclusively suggests corresponding direction such as role performance as a means of urban growth management, promotion of quality of life by accumulating social capital, introduction of socially sustainable management program for the new towns, discovery and creation of town's value, reexamination of self-sufficiency's meaning or target, selective deregulation of metropolitan development, institutional strategy for cost reduction, changeover from house index to urban function oriented index, and pursuit of low-carbon green town.

Because of the demographic and economic changes and the lifestyle diversification, the new housing types such as the Quasi-housing and urban small-size multi-unit housing are appeared in korea. The current housing use classifications are regulated in accordance with the housing divided ownership, horizontal and vertical size of housing, and the number of units. However, there is a limit to accommodate the new housing type. Therefore, this study proposed the direction of improvement of the housing use classifications through comparative analysis of foreign housing use classifications. Also, building regulations are applied according to the building use classifications. Therefore, the new housing types in building act are very urgent and important. So this study is derived the problems of the current housing use classifications and is proposed the improvement direction of it through the expert opinion survey.

Energy systems in increasing energy efficiency are actively performed at home and abroad. But Generally systems in the country are limited in a new building or sort of some buildings like a public and office building. So, this research suggest a new direction of energy system for existing buildings. It need to set a new bound for containing the green remodeling. For a direction, we analysis domestic energy system in perform and compared their bounds, standard and methods of energy evaluation. This study is necessary for an additional research for proposing detailed evaluation items and for a feasibility study research. And it contribute to develope internal energy systems and set a new system bound.

This paper deals with a newly developed direction indicator system of a car which displays left turn and U- turn signal differently, so that the following driver can identify the Intent of the next car ahead easily. In general, when a car want to change its direction, the driver move the blinker lever below the steering wheel up or down. However, as the left turn and U-turn signal are the same, there always be the risk of rear-end collision by misinterpreting U-turn signal as left turn signal. In this paper, a new direction indicator system which differentiates left turn and U-turn signal is developed. The left turn signal is the same as before, but when a driver want to U-turn, an additional U-turn signal blinks at the rear of the car. By identifying the direction signals clearly, the developed system is expected to alleviate the risk of car accident.

This paper validates new type electric power steering (EPS) system which is driven by a uni-direction rotational motor and two electromagnetic clutches. The assist motor of the new type EPS produces a torque for assisting the steering in only one direction and two electromagnetic clutches transmit the assist torque to the pinion gear in either left or right direction with respect to the steering rotation. In order to evaluate the static and dynamic characteristics of the new type EPS, the EPS has been modeled by using the well known customized software such as MSC.ADAMS and MSC.CarSim. The ADAMS software has been used to investigate the static characteristics of the proposed system. ADAMS, however, can not describe dynamics of a vehicle and perform the simulation under the various road conditions. Thus the dynamic characteristics of the vehicle including the EPS are analyzed very well by using the CarSim software. A sinusoidal steering input command is applied to the propose EPS system in order to evaluate the static characteristics, while the double lane changes are applied to the vehicle with the EPS in order to evaluate the dynamic performance. Through a series of simulations, we can conclude that the propose EPS shows the stable dynamic characteristics when the rotational direction is changed.

Objective : Today, a study about the meridian is at a standstill because there is no any fundamental study to verify an essence of meridian or to take advantage of meridain. It searched the direction of new meridain study by making out road-map about meridain study to overcome the standstill. Method : It has had a through grasp of the problem of meridian study through analysis of papers for degrees and academy journals of study in connection with meridian published till now. It has made out road-map of Meridian study under a principle establishing road-map because of these problems. Results : The major problems of former studies about meridain are as follows. One is not to have any cooperation with other medical fields. The other is not to have any practical study. It searched the direction of new meridian study by road-map detailed as well as overall to overcome the difficulties. Conclusions : The new direction of meridian study is to build ideal methodical frame and modern meridian model through studying of among school systems. It will interpret newly and modernize traditional meridian theory with being connected with science technology.

Data economy era is rapidly approaching where big data plays the pivotal role of creating new values and solving various problems. This paper aims at designing Korea's new strategic direction of informatization in the big data age. For this purpose, paradigm shift of our society and the new role of IT together with the discussion on open platform and big data focused on its potentials and new possibilities are analyzed, which leads to the conclusion that big data will be a main engine for creating new values. Based on the results of the analysis, three kinds of strategic direction is designed. The first direction is on national vision making and 'data analysis-based creative nation' is suggested. The second direction is on catalyst making and 'smart government utilizing the power of big data' is proposed in details. The third direction is on sustainable leading mechanism and 'collaborative governance between stakeholders' is suggested.
