박병욱,이창재,서상일 한경대학교 2008 論文集 Vol.40 No.-

In this study we took the aerial photos scaled 1:5,000 with aircraft equipped GPS/INS. DEM was generated by automatic image matching method using the exterior orientation parameters obtained by GPS/INS, and the ortho-images were produced by differential rectification based on that. As the result of measurement of RMSE based on digital map for ortho-images produced with GPS/INS data, the horizontal position error was 61cm that was good enough to satisfy the precision demand of 1:1,000 ortho-image map. There were no big differences in precision of ortho-images between GPS/INS and aerial triangulation process. It seems that the producing method of ortho-image using GPS/INS data can be speedier and more efficient method than traditional method using aerial triangulation

An embedded home automation system with PXA255 was designed and implemented in this paper. TV receiver system, visitors' image storing and checking system with USB camera are implemented in this system. Fire, gas leaking, and intrusion alarms with several sensors are implemented too. TCLN9081DA27D TV tuner was used for this system and its device driver was implemented for PXA255 embedded system. USB camera was used for capturing of visitors images, and the captured images can be displayed in the TFT LCD monitor. TDUHC124B USB host controller was used for the interfacing between USB camera and implemented embedded system. The captured images from USB camera can be compressed as JPEG and stored as files. The stored images can be displayed in the TFT LCD at any time.

To investigate the annual distribution of hepatitis B surface antigen (HBs Ag) in healthy adults, this study was performed by means of counter-immunoelectrophoresis'with sera obtained from 4,145 healthy adults who reside in Seoul and Gyunggi-Do area from January to December, 1980. The experimental procedures were same with the previous reports. The subjectives were consisted of two groups: one is mass life group (3,152 adults) and the other, home life group (993 adults). The results were as follows; 1. Among the 4,145 cases tested, 283 cases (6.83%) showed HBs Ag positive. HBs Ag positive rates in the group of mass life and home life were 6.69% and 7.25%, respectively. 2. Whereas the positive rate of HBs Ag in the aspect of the differencies of mass life duration was not significant, upper class group showed slightly high positive rate. 3. In seasonal variation, it showed relatively high positive rate (8.5%) in spring, and AB blood group showed higher rate (7.87%) than the other blood groups. And then, western seaside area in Gyunggi-Do showed slightly high positive rate (7.5%) in areal distribution.

To determine the optimum ventilation systems during long tunnel excavation, the velocity vector profile and the contaminant's distribution at working place are studied using 2-D, 3-D numerical analysis. The main results can be summarized as follow; In case of long tunnels, blower-exhaust-mixture types which enable to use soft blast ducts is most appropriate in terms of ventilation and economical efficiency. Of the same ventilation types, ventilation efficiency has a difference according to blast ducts and the distance between fan and working place. The 3-D numerical result shows that arranging blower and exhaust ducts in the right and left corners of the tunnel respectively is effective to discharge contaminant. The result of the real measurement shows that CO concentration can be reduced to below 50 ppm, which is regulation value, as 16-minutes fan operation goes on.

전용 에이전트를 이용한 실시간 웹 서버 침입탐지

田炳旭 水原大學校 2005 論文集 Vol.23 No.-

As the Internet and its users are rapidly increasing, the existing firewall and the related techniques are faced serious limitations to detect various types of attacks which exploit vulnerability of web server. Today, most intrusion methods utilize the web application programming error and its mechanism. In this paper, a method is proposed by using the real-time web-server agent. The agent analyzes web-server based log and detect attacks based on the analysis of web-application's vulnerability. The real-time agent removes process ID(pid) and block out attacker's IP when it detects the intrusion through the decision stage after analysis types and patterns of attack.

GIS를 이용한 지하매설물 관리 방안

박병욱 호남대학교 1995 호남대학교 학술논문집 Vol.16 No.2

This paper proposes subjects to consider when GIS technique is introduced to effective management of underground facility. They are as follows : First, the scale of digital maps for underground facility management should be larger than 1/500. Second, accurate survey about actual facility condition must be carried out, in terms of enough time and cost, by facility location detectors. Third, surveying by total station or GPS equipment is adequate to aquire saptial information of underground facility which position determined by detectors. Finally, synthetic data management by exclusive department is necessary, and continuous management is very important.

TFD는 기능이 알려진 짧은 DNA sequence(signal)들과 그와 연관된 저널 자료로 구성된 데이타베이스이다. 임의의 DNA에서 이 데이타베이스의 sequence들을 검색하여 signal을 찾는 프로그램으로 Dan S. Prestridge가 개발한 SIGNAL SCAN이라는 프로그램이 사용되고 있는데, 이는 간단한 문자열 비교 알고리즘을 사용한다. 본 연구에서는 계산상 보다 효율적인 검색을 위해서, TFD의 sequence를 검색하기 위한 automata를 구성하는 프로그램과, 이 automata에 따라 signal을 검색하도록 하는 TFSCAN이라는 프로그램을 개발하였다. 검색된 signal에 대한 관련 문헌의 검색에서도 인덱싱 방법을 이용하여 계산 속도를 향상시켰다. 프로그램의 사용을 단순화시켰고, 결과 내용을 signal과 관련된 모든 정보를 일목요연하게 보여줄 수 있도록 구성하였다. 이 프로그램을 Web을 통해서도 사용할 수 있도록, GINet Web 서버에 TFSCAN 입력용 form과 CGI 프로그램을 개발·설치하였다. 본 연구의 특정 Motif 패턴으로 구성된 데이타베이스 검색에서, automata를 응용한 알고리즘을 이용하여 계산상 급격히 향상된 결과를 얻을 수 있음을 알 수 있었는데, 이는 생물학의 여러 패턴 검색에 응용될 수 있을 것이다. 더욱 민감한(sensitive) signal 검색을 위해서, 이와 같이 automata를 활용하고, 이 automata를 최적화하는 알고리즘 연구를 계속하고 있다. TFD is a transcription factor database which consists of short functional DNA sequences called as signals and their references. SIGNAL SCAN, developed by Dan S. Prestridge, is used to determine what signals of TFD may exist in a DNA sequence. This program searches TFD database by using a simple algorithm for character string comparison. We developed TFSCAN that aims at searching for signals in an input DNA sequence more efficently than SIGNAL SCAN. Our algorithms consist of two parts, one constructs an automata by scanning sequences of TFD, the other searches for signals through this automata. Searching for signal-related references is radically improved in time by using an indexing method. Usage of TFSCAN is very simple and its output is obvious. We developed and installed a TFSCAN input form and a CGI program in GINet Web server, to use TFSCAN. The algorithm applying automata showed drastical results in improvement of computing time. This approach may apply to recognizing several biological patterns. We have been developing our algorithm to optimize the automata and to search more sensitively for signals.

This paper discussed some issues of-This study examines the structure and its meanings of Modern Simcheongjeon , which is a popular drama. The results run as follows. The first, its unrealities are taken off, which are Simcheong's death and renewal, a blind Sim s reunion with Simcheong and his eyesight recovery. Through its symmetrical form and its antagonistic structure, Simcheong's filial duty is placed emphasize. The second, it has a repeated structure, which is consisted of songs and words. The songs are all spoken of the filial duty as a traditional truth, which should be followed after in the industrial world. They are all filled with the general truth of the filial duty and stories of its tangible practices. The last, it not only recognizes actual conditions in the contemporary world, but also satirizes the prevailing states of society. Therefore, it emphasizes the moral superiority of the filial duty. This study has left assignments of explicating a genre of the popular drama and Mangeok and placing it in the drama-history.

위험과 대응의 파급효과에 대한 정량적 산출법

田炳旭 水原大學校 2004 論文集 Vol.22 No.-

Today, many attacks on the Internet are focused on IT infra itself rather than specific systems. Also huge capacity of network and lightening speed of the communication make possible more sophisticated and intelligent attacks to the system. Several methods are used to protect the system against those attacks - such as prevention, cure, and mitigation. However, these methodologies have a fatal limitation caused by the behavior of human being that is structured on time based think pattern. In this paper, the threat and the vulnerability that have to be overrun by system designers are defined. The method that calculates the quantitative estimation of spreading effects in realtime response against those threats has been presented. And a policy that selects an optimal protection method is proposed.
