With increasing the quality of life in proportion to the national income, we have had cars as more convenient and safe means of transportation for a long time. The more we have the benefits from cars, the more seriously we should consider problems such as the destruction of the environment by air pollution, traffic accidents, parking problems, traffic congestion, etc. as social cost caused by the increase of cars. Among them, the traffic accidents are very serious, especially the accidents of the business cars occurs five times more than those of the private cars. Therefore if we analyze the cases of the various kinds of syst.em, test the results and apply them to business cars, we will reduce the traffic accidents of business cars.

Because each building is built in different time, there exists different equipment to meet the need for each age. Before the announcement of "Community Management Regulation", the old communities usually suffer the problem of lower requirement and living quality. This may bring some security problem that we should face. In this research, we construct "Building Administration System" to provide users a tool to perform a standard operation procedure in community management. This powerful tool will also help manager to effectively handle important tasks in property administrating by reducing unnecessary documentation. In the current regulation, all community committee members shall be voted each year. This will seriously affect the cumulative of management knowledge and cause a worse efficiency. In this research, we use Object Oriented concept and Visual Modeling techniques to combine with Interbase, ER/Studio, and Delphi to develop this management system for Building Property. Through the help of current computing technology, we can solve the problem that can not be inherited and the storing of the huge amount of data. In this system, we develop the modules such as Basic Data Module, Administrative Expense Calculation, Receipt Print, and Inquiring for Inheritance. In this system, we have integrated all houses, parking lots, and public equipments in it. Manager will only need to handle some basic accounting data; the system will automatically handle the rest. Through the help of this system, the community management staff can be easily accomplished and put more manpower on some needed aspect to improve the living quality.

자동차 보급 증가로 인한 주차 공간 부족 문제는 불법 주정차 차량 발생의 원인이 되어, 교통 체증을 야기하는 심각한 사회문제가 되었다. 따라서 각 지방자치단체에서는 불법 주정차 문제 해결을 위한 법안을 마련하기 위해 노력하고 있으며, 불법 주정차문제를 해결하기 위한 연구가 진행되고 있다. 한편, 정보통신의 발달에 의해 데이터의 양이 매우 빠른 속도로 증가하고 있으며, 아울러 공공 데이터의 양도 매우 빠른 속도로 증가하고 있다. 따라서 공공 빅데이터를 효율적으로 처리하기 위한 연구가 필요하다. 그러나 현재 공공 빅데이터 관리 및 분석을 수행하기 위한 효율적인 시스템을 구축하는 데는 아직 미흡한 실정이다. 따라서 본 논문에서는 불법 주정차 데이터와 같은 공공데이터를 효율적으로 분석하고 효과적인 주 정차 단속을 위한 하둡 기반 불법 주 정차 데이터 관리 및 분석 시스템을 제안한다.

Baby boomers who have rebuilt the Korean economy over the last half a century are now transitioning into a silver generation who are over 65 years of age. New silver consumers are qualitatively and quantitatively different from the previous generation and are considered to be 'the single most consumption-leading generation.' The number of new silver consumers using department stores and traditional markets has increased. SPSS ver. 21.0 was used with the methods of frequency analysis, t-test, one-way analysis of variance (ANOVA), device master record test, and regression analysis. This research studies consumer satisfaction of new silver consumers on department stores and traditional markets among retailing. The improvement of the parking environment is the most urgent issue for traditional markets because the long-term assessments of parking areas indicate that it is necessary to provide improved convenience for consumers. Salesman satisfaction has improved and consumer satisfaction ranks salesman satisfaction high for traditional markets; however, price satisfaction is low and the distribution system should be improved to supply products at a lower price. Salesman and price satisfaction should be improved at depart stores. Traditional markets should also promote consumer satisfaction through consistent management to make consumers trust information in regards to quality control and production and distribution; in addition, department stores should increase consumer satisfaction by maintaining store systems such as product diversification and display, cleanness, and atmosphere.

Purpose - This study aims to analyzing of solar power generation cost-benefit. Design/methodology/approach - We analyzed whether there is economic feasibility by selecting parking lots and idle sites located in four areas of Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang areas nationwide, and analyzing site conditions and installation capacity. Findings - According to the results of the analysis, it was found that there is low profitability in Seoul, Gyeonggi and Chungcheong regions, where the solar radiation was not excellent even if REC is selected through the contract market. However, it is necessary to analyzed the economical validity the profitable validity including environmental benefits (greenhouse gas reduction, NOx, SOx reduction effect) and social benefits (renewable power supply) that is analyzed by income and operating costs which is occurred from electricity sales and REC sales when installing solar power generation facilities. Research implications or Originality - In this study, economic feasibility was evaluated additionally in consideration of environmental and social benefits. In conclusion, it was shown that businesses are not economical when considering only simple financial aspects are also sufficiently economical when it is considering environmental and social benefits.

In this paper, we develop protype of wierless recognition system using low frequency. Application of this system is very broad. Namely, High-way toll gate, animal management, parking system and industral automation et al. This system is composed of controller, decoder and tag. Controller is personal PC, decoder is signal module and tag is mobile corresponder module. Modulation is ASK, 4,800bps, frequency is 120/60kHz and transmission length is about 80cm. And now we study improvement of stability, low power consumption, compact of tag and transmission length improvement.

홈 네트워크는 사용자에게 많은 정보서비스를 제공하여 준다. 특히, 다양한 센서 데이터를 활용함으로써 그 서비스의 종류와 질을 풍부하게 한다. 하지만 홈네트워크는 현재 멀티미디어 서비스에 집중함으로써 그 서비스의 활용폭을 스스로 제한하고 있는 실정이다. 특히 댁내 통신망에 집중함으로써 실내의 여러 가전기기를 제어하는 데는 많은 성과를 얻고 있으나 실외의 여러 기기를 제어하는 데는 큰 성과가 나오지 않고 있다. 실외의 여러 기기는 실내의 가전기기와 다르게 특정 기능을 강조하는 형태로 구성되는 경우가 많기 때문에 여러 기능을 가진 센서보다는 한 두가지 기능을 가진 센서를 활용하여 시스템을 구성하면 되기 때문에 실내에서 센서 노드를 사용하는 것보다 훨씬 경제성도 높다고 할 수 있다. 본 논문에서는 현재 가장 많은 사용 목적을 가진 여러 가지 기능 중 동작 센서를 선택하여 이를 활용할 시스템으로 주차장 관리 시스템을 선택하여 이를 홈 네트워크에 접목하여 구현하여 보았다.

최근 서울에 자동차 보유 대수가 급증함에 따라 주거나 상가 밀집 지역에서 주차 문제는 갈수록 심화되고 있어 이에 따른 주차공간 확보 및 기존 주차 공간의 활용할 수 있는 시스템이 요구되고 있다. 따라서 본 논문에서는 공유경제 개념을 도입하여 개인이나 단체가 소유하고 있는 주차 공간을 사용하지 않는 시간대에 주차 가능 공간을 다른 사람들과 공유할 수 있는 시스템을 제안한다. 본 플랫폼은 웹, 안드로이드, 라즈베리파이, 데이터베이스로 구성되어 있으며 실제 주차장에 설치된 초음파 센서와 CCTV 이미지를 분석하는 OpenCV를 이용하여 현재 주차장의 사용 중인 공간과 비사용 중인 주차 가능 면수를 분석하고 분석한 정보를 사용자들에게 제공한다.

In this paper, a solar energy powered bicycle linked to a wireless sensor network (WSN) which monitors the transfer of solar energy to an electrical energy storage unit and an analysis of its effectiveness is proposed. In order to achieve this goal, a solar-powered bicycle with an attached ZigBee and a far-end wireless network supervisory system is setup. Experimental results prove that our prototype, solar energy powered bicycle, can achieve enough solar energy for charging a two lead-acid battery pack. As a result, the user, through use of a wireless network in the parking period can be kept aware of the data on the amount of immediate solar radiation, the degree of illumination, the ambient temperature, and electrical energy storage capacity information of the bicycle through an internet interface.
