Recently, worldwide government policy is pursuing saving energy and preservation. add to this, the solar cells are getting the spotlight nonpolluting energy source, using a variety of products for solar cell. in this paper, we'll make solar tracking system for suitable of dynamic boat. we knew that general boats are using fixed solar cell, it's first time to use tracking system of solar cells for boats so it is hard to application. To solve this problem in this paper we use to a magnetic compass and GPS for suitable solar tracking system of dynamic movement and to analyze fixed and tracking solar system. frist. solar tracking device is designed two-axis control system. one-axis control system is taken a magnetic compass for making efficiency defence solar tracking sensor, two-axis control system apply GPS latitude and longitude data for SPA(Solar position algorithm) so we know the azimuth and altitude. it analyze data value of accuracy comparison from result. so the proposed algorithm confirm to have validity.

This study deals with the traffic accident of circular intersections. The purpose of the study is to develop the accident models by traffic violation type. In pursuing the above, this study gives particular attention to analyzing various factors that influence traffic accident and developing such the optimal models as Poisson and Negative binomial regression models. The main results are the followings. First, 4 negative binomial models which were statistically significant were developed. This was because the over-dispersion coefficients had a value greater than 1.96. Second, the common variables in these models were not adopted. The specific variables by model were analyzed to be traffic volume, conflicting ratio, number of circulatory lane, width of circulatory lane, number of traffic island by access road, number of reduction facility, feature of central island and crosswalk.

Fisheries resources, due to their intrinsic biological -density dependent, and socio- economic -common property nature, might yield the sustained benefits to the society involved, depending on the degree to which the social management scheme, pursuing the optimum yield from each of them, is framed. And besides, the success or failure of the management on them would, with no doubt, lead parallelly to the direction on scientific study of "Natural Resource Economics." Thus the objectives of the management, to ensue the best use of these society's resource, should underlie the technical, economic, ana social efficiency all together to meet the maximization of society's benefits from yields, taking account of managerial efficiency. And those multiple conflicts need communications between biologists, social scientists, and managers given tile mandate, tobe coordinated to arrive at a unique value weighed, through the well-ordered system approach and resulting timely decision-making which accommodates dynamical fisheries aspects and varying social purposes. purposes.

최근 주택을 선택함에 있어 주거환경에 대한 관심이 고조되고 있으며 이 가운데 강 또는 산 등 특정 대상으로의 조망과 개방감 여부가 주택가격을 결정짓는 중요한 요인으로 작용하고 있다. 실제로 기존 재고 주택시장의 아파트에 이러한 경관가치가 프리미엄의 형태로 주택가격에 내재되어 있는 것으로 나타났다. 따라서 신규 주택을 공급할 경우 특정 대상으로의 조망이나 개방감 여부를 판단할 수 있는 수단이 필요한 상황이다. 이에 본 연구에서는 3차원 시뮬레이션 프로그램(3D Studio Max)를 이용하여 개방감을 측정하는 방법을 모색하고자 하였다. 연구 결과 3차원 시뮬레이션 프로그램을 이용하여 개방감의 유무와 정도를 파악하는데 유용한 수단으로 이용될 수 있으며 이외의 다양한 목적으로도 활용될 수 있음을 제시하였다.

Brand is a useful tool for modem people living under the age of the brand, to explain the information of their products by differentiating themselves from others. It also represents the value of company and plays a major role convincing customers. Even living space brands are no exception. According to the development of marketing management ability, living space brands require the new sales strategy to dominate the market over the business competition, and plan differently for a changing market environment. On such account, companies are commercializing the living space via establishing its brands. Thus the study will cover the living space differentiation strategies for promoting the brand images of respective construction companies and will strive to compare and analyze the differentiation strategy factors that construction firms are pursuing through case analysis framework. Moreover, it's objective focuses on materializing the strategies of living space in accordance to the brand application elements.

PURPOSES : This study dealt with traffic accidents occurring within roundabouts. The objective of this study was to analyze safety effect by introduction of roundabouts. METHODS : In pursuing the above, traffic accident data on roundabouts are collected and compared. For the analysis, collected data were separated as all intersection points, turning lane accident, approach lane accident by geometric design. RESULTS : Through the study results, it was found that the total accidents decreased by 55 accidents/2 year with safety effect of roundabouts. Also the result shows that accidents by point of two-lane roundabout at turning lane(0.26) and approach lane(0.27) is risky than total accidents by point(0.09). Moreover, accidents by point shows high value as diameter of a roundabout is bigger. CONCLUSIONS : When a roundabout is introduced at the intersections there are safety effects by reduction of traffic accidents.

This study evaluates the strength of surface treatment parts using the hard anodizing method to the aluminum alloy brake disks. In order to achieve weight reduction of vehicles, Eco-friendly cars parts of the high-quality and competitive price is to equip. Especially while pursuing parts of weight reduction, it has to maintain the strength of the surface of the brake by nature. To enhance surface strength of aluminum alloy, we use hard anodizing technology in the surface treatment. This study is resulted of 3 times greater the hardness value of the hard anodized specimen than the aluminum alloy specimen for the lightweight parts of EV brake disk

The purpose of this study is to study the inner meaning and formative with distorted and atypical Informel image, body image expressed in modern fashion. Method of the study is as follow. The study method examined philosophy of art 19th century?in order to consider interconnections between social and cultural characteristics of expressionistic abstract art, a form of Informel and changed physical style. Based on this method, the Informel image that appeared in the plastic arts in terms of artistic significance and aesthetic value was examined. Based on the above discussion on modern fashion Informel images were expressed in any formative characteristics were considered. The results of this study are as follows. Contingencies through the spontaneous act of art to transcend the image of atypical lines formed elements of coincidence, was developed. Liberation was expressed from liberation of physical boundaries and created outward expansion of the free formative. Atypical was organic forms pursuing spontaneous plasticity and diversity, and appeared in the form of distortion and deformation.
