완전 무인 매장의 AI 보안 취약점: 객체 검출 모델에 대한 Adversarial Patch 공격 및 Data Augmentation의 방어 효과성 분석
이원호,나현식,박소희,최대선 한국정보보호학회 2024 정보보호학회논문지 Vol.34 No.2
코로나19 팬데믹으로 인해 비대면 거래가 보편화되면서, 완전 무인 매장의 증가 추세가 두드러지고 있다. 이러한 매장에서는 모든 운영 과정이 자동화되어 있으며, 주로 인공지능 기술이 적용된다. 그러나 이러한 인공지능 기술에는 여러 보안 취약점이 존재하고, 이러한 취약점들은 완전 무인 매장 환경에서 치명적으로 작용할 수 있다. 본 논문은 인공지능 기반의 완전 무인 매장이 직면할 수 있는 보안 취약점을 분석하고, 특히 객체 검출 모델인 YOLO에 초점을 맞추어, 적대적 패치를 활용한 Hiding Attack과 Altering Attack이 가능함을 보인다. 이러한 공격으로 인해, 적대적 패치를 부착한 객체는 검출 모델에 의해 인식되지 않거나 다른 객체로 잘못 인식될 수 있다는 것을 확인한다. 또한, 보안 위협을 완화하기 위해 Data Augmentation 기법이 적대적 패치 공격에 어떠한 방어 효과를 주는지 분석한다. 우리는 이러한 결과를 토대로 완전 무인 매장에서 사용되는 인공지능 기술에 내재된 보안 위협에 대응하기 위한 적극적인 방어 연구의 필요성을 강조한다. The COVID-19 pandemic has led to the widespread adoption of contactless transactions, resulting in a noticeable increase in the trend towards fully unmanned stores. In such stores, all operational processes are automated, primarily using artificial intelligence (AI) technology. However, this AI technology has several security vulnerabilities, which can be critical in the environment of fully unmanned stores. This paper analyzes the security vulnerabilities that AI-based fully unmanned stores may face, focusing particularly on the object detection model YOLO, demonstrating that Hiding Attacks and Altering Attacks using adversarial patches are possible. It is confirmed that objects with adversarial patches attached may not be recognized by the detection model or may be incorrectly recognized as other objects. Furthermore, the paper analyzes how Data Augmentation techniques can mitigate security threats by providing a defensive effect against adversarial patch attacks. Based on these results, we emphasize the need for proactive research into defensive measures to address the inherent security threats in AI technology used in fully unmanned stores.

李元浩 釜山大學校 學生生活硏究所 1966 硏究報 Vol.3 No.1
An investigation was made of 420 students -210 male and 210 female-for the First Semester of 1966. The form of questionaire for the inquiry is based on the Mooney Problem Check List. The questionaire with 220 questions under 11 prblem areas was made out as shown below. The problem areas of the students of our university resulting on the same inquiry are as follow: 1. Social and Recreational Activities...14.0% 2. Personal Psychological Relations...12.1% 3. The Future:Vocational and Educational...11.5% 4. Finance, Living, Coditions and Employment...10.3% 5. Adjustment to School Work...10.0% 6. Social-Psychogical Relations...9.2% 7. Curriculum and Teaching procedures...9.2% 8. Courtship, Sex and Marriage...6.4% 9. Health and physical Development...6.0% 10. Moral and Religion...5.3% 11. Home and Family...5.3%

We can't define easily the exact meaning of studendt power which is recently causing troble; it is still premature to give a compete definition and difficult to establish any criteria of evaluation of student power activitles. But I here might say that the distance and gaps between the ever-changing socity and educational institution is one of the important factor of student uprising. Therefore, I think, one of the way to slove this student problems is to shorten and to correct this distance laid between society and educational institutions, and the educational institution itself should be changed and try to be adjusted to the ever-changing society through continow self-im-provement. Most people are of the same opinion that recent troubles of educational institution in the many countries should be dealt with as a contagious pathological matters. The factors of student power can be appeared to active movement and efforts to improve modern society involoved the cease of conversation, information gap and discontent to the established system. But it is afraid to be apt to fall into anti-intellectualism that justified partial sudversive activities. They, so-called T.V-generation, must not be dealt with the old view of value and standard only. namely, it is indicated that this generation has particular the factor that can not be understood with the old senses and thought. These student power on other side can be understood as possibility of an endless movement of the young generation, while its movement is excessive as the release movement of estrangement from humanity caused by industrialization, mechanization and mangement. We must find out rationally cooperative relation between student and existing generation to solve the matters of student power.
목질진흙버섯(Phellinus linteus) 액체배양에 의한 현미와 원목에서 자실체 형성

The main objectives of this study were to fruit body of Phellinus linteus using liquid spawn. Highest mycelial growth and in vitro fruiting was observed when 180㎖ of water was added to 200g of brown rice in 1000㎖ PP bottle. Optimum inoculum amount was 100ml per bottle. Better mycelial growth and fruiting were observed when the amount of brown rice was lowered. For timber log culture of P. linteus, low contamination was observed when logs were sterilized for as low as 60 mins. But, best mycelial growth was observed when the logs were sterilized for 120mins. Among different log types, highest mycelial growth and fruiting were observed in oak and mulberry. Only few fruiting could be observed in birch, chestnut, alder, while no fruiting was produced in Aspen. Best fruiting was produced from isolate PH- 211, although other isolates also produced few fruiting.
Deck Plate 를 사용한 合成보에서 쉬어 코넥터의 强度에 관한 硏究

The strength of stud shear conncetors in steel and concrete composite beams have been derived through the push-out test or beam test. Of the two, push-out test method is generally used because of simplicity and convenience of experiment. But, in push-out test, stud shear connectors have stress distribution different from beam test. Therefore, it is necessary that applicability of a stud strength formula derived from push-out test in this study, to design of composite beam, is investigated.
