컴퓨터 기술이 발전함에 따라 시스템 공격 기술이 점점 더 진화하고 다양화 되고 있다. 컴퓨터의 하드웨어와 소프트웨어는 점점 진화하고 성능이 향상되고 있지만 기본 동작 원리는 거의 변화하지 않고 있어 문제 대두되고 있다. 일반적으로 응용프로그램들이 실행상태에 놓이면 프로그램의 데이터들이 메모리에 놓이게 된다. 이러한 데이터들은 운영체제 동작의 효율성 때문에 메모리에 남아있게 되어 메모리 해킹이나 메모리 분석을 통하여 데이터들에 접근할 수 있게 된다. 그로 인하여 사용자의 개인정보, 암호화된 키, 인증서 등이 유출되어 큰 피해가 발생하기 때문에 대응 방안이 마련 되어야 한다. 본 논문으로 메모리 해킹에 대한 문제점과 그에 대한 대응책을 제안한다.

With the globalization of economy, there is keen competition among countries to be a logistics hub and companies are striving to be first in establishing logistics system centering on advantageous sites, especially airport and seaports, to perform supply, production and distribution. Korea competing with Northeast Asia countries is also working out strategies in order to make Korea penninsula a logistics center of Northeast Asia taking advantage of its geographical strength. Gwangyang port has designated as Free Economic Zone together with Pusan and Jinhae, Incheon from October 24th, 2003. However, the introduction of Free Economic Zone in Korea lagged behind other major countries and it has a lot of operational problems. Approximately 600 areas worldwide are designated and operated as a Free Economic Zone and Gwangyang port and its surrounding area has several points to be settled as one of FEZ. First one is its limited functions and related laws on Gwangyang Bay. Next is imperfection on development, investment and management system of the FEZ. Lack of promotion activities could be one of the problems. If we want to activate the FEZ, we must induce investment at Gwangyang Bay. This paper analyzes the above problems and presents various measures to activate Gwangyang Free Economic Zone by inducing investment for innovation cluster as follows Benchmarking to promote Gwangyang Free Economic Zone as follows Benchmarking other countries' system, governmental support, introduction & logistics functions, early development of the hinterland, supply ofeffective one-stop service, investment attraction into the area and diversified promotion & marketing activities.

The development of IT has made it possible to use various terminal systems for financial transaction and demands for financial survices are getting more and more diversified at the same time. Among others, mobile banking service market based on IC chips has been expanded its service areas and the number of mobile banking users has been increased. The study analyzes and tests the dynamic effects of the inflow of potential customers on mobile banking market condition by using system dynamics methodology to identify the dynamic structure of mobile banking market. The simulation model is designed to track the variation in the number of subscribers of mobile banking servides according to two scenarios, and the results are as follows; First the effect of word of mouth by customers who have used the service already is significant. The satisfactory level of early adopters is reflected in WOM, and as a test result shows, increase in word-of-mouth causes the growth of potential customers' demands for mobile banking service. Second, perceived attractiveness of mobile banking service market is another important construct. Factors such as convenience, mobility, time saving, security, and various services explain the construct perceived attractiveness of the service, and it makes the potential customers adopt the service, causing the increase of demands.

It is very hard to analyze the train derailment safety quantitatively at the curved section because of the diversified affect parameters including the complex interaction between wheel and rail, the train conditions such as the shape of wheel, suspension system, the track conditions such as the radius of curve, cant, transition curve, and the operation conditions, etc. Two major factors related to the running safety of railway vehicle are classified as the railway vehicle and the track condition. In this study, when the railway vehicle passing through curves of actual track condition of subway line NO.3 in seoul ($Yeonsinnae{\leftrightarrow}Gupabal$), the effect that has influence on running safety depending on rail inclination. The analysis result of 1/40 rail inclination condition is more favorable on running safety than other rail inclination conditions because derailment coefficient and wheel unloading ratio are the lowest.

The purpose of this study is to develop living room storage furniture with multiple functions and for analyzing living room system furniture that can correspond with lifestyles in the living room. Literature survey was used by collecting data on interior design books and magazines. System furniture is very functional depending on the purpose and spaces, and can be modified effectively with the development of design based on the resident's demand. Living room furniture was mostly arranged by two types. One was lower and slimmer in order to use the space effectively, the other totally occupied one side of the living room wall. Furniture combined with multiple functions of lights and electronics can increase the satisfaction and convenience of users. And furniture maximizes storage space and is systemized so that mixture and arrangement are diversified. Flexible and active way furniture that accept various electronic fixtures and performances in the living room. Furniture forms, materials, and colors will be designed for the functions and atmosphere of living rooms. This results will contribute to develop furniture that has additional features such as lighting and electronic appliances hereafter.

현재의 영상감시 시스템은 3세대로서 영상장치는 저화질에서 고화질로 발전하였으며, 영상감시 솔루션은 단순형에서 지능형으로 발전함으로써 영상감시 성능이 향상되었다. 그러나 이러한 영상감시 시스템에 대한 장비 및 기술이 복잡해지고 다변화되면서 더 빠른 네트워크 속도, 안전한 전원공급 등 기반 인프라에 대한 의존성이 더욱 높아지고 있는 한편, 전력 및 통신과 같은 기본 인프라가 제한적인 지역에서의 영상 감시 지원에 대한 필요성이 증가하고 있다. 본 논문에서는 이렇듯이 기본 인프라가 제한적인 지역에서 지능형 영상감시를 지원할 수 있는 시스템을 제안한다.

Today the pedestrian-related problems a key subject requiring the attention of the traffic engineers for improving the transportation system. Particularly in urban and CBD locations, the pedestrian presents an element of sharp conflict with vehicular traffic. Therefore pedestrian movements must be studied for the purpose of providing guideline for the design and operation of walking transportation systems. This paper is to address the characteristics of walking transportation in a big city. Especially the focuses are emphasized on the ratio occupied by pedestrian traffic among the whole unlinked trips in a city and walking time. The data for analysis are collected in Seoul metropolitan city through sampling 1,006 citizens. Compared with other similar research works this paper utilized diversified tools to acquire more useful results. Finally, policy directions for pedestrian environment improvement were suggested.

In modern society, the role of university becomes diversified and the concerns on building construction or landscape architecture considering beautiful landscape and scene are increasing caused by increasing interest on external environment of campus. But relative importance of concerns for the context of landscape architecture in campus is neglected rather than other facilities. So the landscape architecture service could not be conducted well. Therefore the computerization of system or management program will be needed for effective landscape architecture tree management and sufficiency of concerns on continuously increasing landscape architecture in campus. The computerization of landscape architecture tree management will be important roles not only to raise the efficiency of landscape architecture management and the view of outdoor environment but also to increase the competitive power of rapidly changing university environment and the quality of education.
