For making teaching-aids with the examples which can improve the ability of the usage of electric home appliances efficiently, first the basic function and the elementary function were extracted from the part of electric home appliances such as an electric iron, an lighting fixture, a washing machine and a refrigerate in the middle school textbook, subject of living technique. And then the methods of repairing the electric home appliances from any other states of obtacle was systematized. On the base of these systems, the teaching-aids were able to be invented from the source of management-examples of electric home appliances. For putting these projects to practice, yearly management-example plan table was designed. From the teaching-aids table of the management-example, the materials for lesson were able to be made. Lesson-developing-idea which is applied to the educational material belonging to the functional lesson process model was suggested, and then the results of the management-function were evaluated. was systematized. The example-centered teaching-learning method and the method which is imposed home project for the sake of efficient usage of electric home appliances got remarkable good consequences, for example, increasing of interest in the lesson 8%, improvement of degree of the accomplishment in learning ability CR 7.36. It means a improvement of conciousness of accomplishment that the studied class marked 61% of the high level(The high level of the compared class is only 38.4%) by way of making the students evaluate themselves by the evaluation criterion of the management-function. This result reveals that teaching individually even in the class with overcrowded can be possible. As the parents' cooperation was good enough to carry out home project at home, the students were able to take a lot of practices and experiences. So they could have improved their management-function. (First evaluation difference was 2.8% and second evaluation difference was 0.8%) The conclusion of this study the previous content is something like these next. 1. Teaching-learning got started, according to the lesson process model planned by making cards system with electric home appliances' management examples, and students themselves evaluated management and function by evaluation criterion of management function, and the management function of the studied class(superior of whole areas' studied class-61%, superior of compared class-38%) has improved. 2. The ability of learned through example-centered teaching and imposing home project has very meaningfully improved.( CR:4.17, P<.00l) 3. It is enabled to teach individually even in the class with overcrowded students through evaluating the result of experiment independently by the self-evaluation criterion for electric home appliances ' management function, improper reaction can be immediately corrected and management function can be formed. 4. In the consequense of practicing home project, the ability of usage of electric home appliances in studied class has improved( Around the time of home project's first and second evaluation, the studied class improved three times as much as before and the compared class' management function improved.) 5. In order to solue the home project, the practical problems of home life should be related to the school teaching, and schooleducation could be more superior in quality. To work come true this study efficiently, first the teaching-aids of the management-function about the curriculum of living technique should be invented and spreaded widely. Second, the ties between school and home should be strengthened because of cooperation and instruction of parents at the time of carrying out home project at home. Third, the teacher who teaches the subject of living technique is demanded to design new teaching-aids and make more efforts to that for accurate basic- function-model.

OSINT를 활용한 기업의 정보유출 대응방안 연구

이상찬 동국대학교 국제정보보호대학원 2025 국내석사

클라우드, AI와 같이 기술이 발전할수록 정보보안의 중요성과 인식 또한 나날이 높아지고 있다. 그러나, 개인정보 유출 피해와 침해사고 사례는 줄어들지 않고 있다. 기업의 보안담당자로서 이러한 침해사고를 방지하고자 원인을 분석하였는데, 랜섬웨어와 같은 고도의 해킹 기법보다 외부에 노출되고 있는 기업의 정보에 의한 침해사고가 더 많이 발생하였다. 이러한 침해사고는 보안에 지속적으로 투자하는 기업에서도 종종 확인할 수 있는데, 주로 관리가 미흡하거나 취약한 보안 설정에 의해 발생하였다. 이에, 검색엔진 및 포트 스캐닝과 같은 OSINT를 활용해 사용자 개인정보와 같이 유출되고 있는 정보의 실태를 분석하고, 이를 조치할 수 있도록 정보를 수집하는 방법 및 노출되지 않도록 정책과 관리 방안을 제안하고자 한다. 본 연구는 기법의 개선방안이 아닌, 기법의 일부를 사용한 기업의 정보 유출 현황과 심각성 연구에 초점을 두었으며, 이를 통해 개인과 기업 모두 관리가 미흡하거나 취약한 보안 설정을 줄여 보안이 향상될 수 있기를 기대한다. As technology advances and improves, including artificial intelligence and cloud computing, the importance of information security grows. Nevertheless, the number of privacy breaches and security incidents remains high. As a corporate security officer, I have examined the causes of security breaches and concluded that publicly exposed corporate information, rather than sophisticated hacking methods such as ransomware, is primarily responsible. Even with consistent investment in security, these incidents often occur due to improper management or weak security configurations. This study examines scenarios involving leaked information, including private user data. It uses OSINT tools, such as search engines and port scans, to suggest methodologies for gathering information and strategies for policy and management to prevent such leaks. Additionally, the study analyzes the severity of information leaks within organizations, using OSINT tools as an effective complement to security methods. We believe these findings will help individuals and organizations mitigate weak or vulnerable security configurations and enhance security.

PDT 레이저 시스템에서의 최적 방사 패턴과 광 분포 측정

이상찬 忠南大學校 大學院 2004 국내석사

Photodynamic therapy(PDT)of malignant tumors is an new modality for the treatment of cancers. After intravenous injection, a photosensitizer is delectively retained by the tumor cells so that, after 48 or 72 hours, there is more concentration of photosensitizer in the tumor cells than in the normal tissue. When exposed to light, the photosensitizer will absorb photon energy and produces a singlet oxygen that destroys the tumor cell. In this paper, we designed the laser system and radiation pattern to improve therapeutic effect, using 635nm laser diode. In order to accuracy and statistical output control we controlled laser diode using the constant current control method. We performed simulations about photon distribution in the tissue that laser is radiated, using Monte Carlo Method, and measured temperature of tissue by injected energy using each radiation patterns. Through this, we compared each laser radiation patterns. In an experiment, increased temperature of each radiation patterns was difference about equal injected energy. The laser system operated equally with setting, and confirmed operating stability. Hereafter, We will verify therapeutic effects through an additional experiment.
