딥 러닝 기술의 급속한 발전과 더불어, 이를 활용한 모델들에 대한 보안 위협도 증가하고 있다. 이들 중, 모델의 입출력 데이터를 이용해 내부 구조를 복제하려는 모델 추출 공격은 딥 러닝 모델 훈련에 높은 비용이 필요하다는 점에서 반드시 막아야 할 중요한 위협 중 하나라고 할 수 있다. 본 연구는 다양한 모델 추출 공격 기법과 이를 방어하기 위한 최신 연구 동향을 종합적으로 조사하고 분석하는 것을 목표로 하며, 또한 이를 통해 현재 존재하는 방어 메커니즘의 효과성을 평가하고, 향후 발전 가능성이 있는 새로운 방어 전략에 대한 통찰력을 제공하고자 한다.

This study reviews preceding research for detailed factors to establish development strategies for Korean Hidden Champion firms and classifies strategy factors into internal ones and external ones through specialists' opinions to draw strengths, weaknesses, opportunities and threats of each factor. It also sets hierarchical model to draw up a survey, distributes the survey to groups of specialists and enterprises respectively and then examines consistency ratio. Fifty-four copies of survey whose reliability on responses is secured through examining the consistency ratio are evaluated with their relative importance in factors by using SWOT/AHP technique and their order of priority is determined. Based on their results, development strategies for Korean Hidden Champion firms are established. SWOT/AHP analyses results show that external factors are with the opportunity of industry growth and the threat of intensified competition and market uncertainty and internal factors are with the strength in order of technological competence, construction competence in customer relation and marketing competence. The weakness in the lack of funds, lack of brand awareness in order. This result suggests that external environments of enterprises that more emphasis should be put on the industry growth and aggressive strategies cannot help but be adopted even in a global competition getting fiercer every day are seen more important. Then, it also seems to be thought that the technological competence including R&D and specialization, construction competence in customer relation and marketing competence should internally chosen for strategies to support strategies. The order of priority in development strategies for Korean Hidden Champion firms is drawn as; (i) aggressive S/O strategy which utilizes opportunities by taking advantage of strengths, (ii) W/O strategy which utilizes opportunities by supplementing weaknesses, (iii) diversified S/T strategy which utilizes strengths to make up for threats and (iv) defensive W/T strategy which supplements weaknesses to overcome threats.

A "high-potential employee" is an employee who has been identified as having the potential, ability and aspiration for successive leadership positions within the company and identify employees who have the greatest future potential and make them future-ready to take your organization to success. The primary purpose of this paper is to investigate the relationships of corporate performance on the high potential employee system using the samples from HCCP panel data. This study seeks to identify a significant high potential employee system though empirical research as well. Results of empirical study are summarized. Finally suggestions, implications and limitations of the present study are also discussed. In this article, we explore the role of competitive strategy and technological environment in the introduction of high-potential employees and its link to impact of these performance.

전자정부 표준프레임워크는 공공부문 정보화 사업을 위해서 개발 보급되었으나, 최근 민간부문으로 확대 적용되면서 정부차원의 강제성 없이 자발적으로 오픈 플랫폼 생태계로 진화하기 시작하였다. 또한 전자정부 표준프레임워크는 세계 전자정부 1위의 대한민국에서의 성공적인 안착에 힘입어 개발 도상국을 중심으로 해외로도 확산 조짐을 보이고 있다. 본고에서는 최근 내수 시장의 한계 및 국내 SW 산업 정책이 중소기업 중심으로 이루어지면서 대형 IT서비스 기업들의 해외진출 전략이 공격적으로 전환되고 있는 시점에서 전자정부 표준프레임워크를 중심으로 국내 기업의 장점을 살리면서 단점을 극복할 수 있는 성공 전략에 대해 알아본다.

Recently, the image processing industry has been activated as deep learning-based technology is introduced in the image recognition and detection field. With the development of deep learning technology, learning model vulnerabilities for adversarial attacks continue to be reported. However, studies on countermeasures against poisoning attacks that inject malicious data during learning are insufficient. The conventional countermeasure against poisoning attacks has a limitation in that it is necessary to perform a separate detection and removal operation by examining the training data each time. Therefore, in this paper, we propose a technique for reducing the attack success rate by applying modifications to the training data and inference data without a separate detection and removal process for the poison data. The One-shot kill poison attack, a clean label poison attack proposed in previous studies, was used as an attack model. The attack performance was confirmed by dividing it into a general attacker and an intelligent attacker according to the attacker's attack strategy. According to the experimental results, when the proposed defense mechanism is applied, the attack success rate can be reduced by up to 65% compared to the conventional method.

In major wars of the 21st century, drones are expanding beyond surveillance and reconnaissance to include land and air as well as sea and underwater for purposes such as precision strikes, suicide attacks, and cognitive warfare. These drones will perform multi-domain operations, and to this end, they will continue to develop by improving the level of autonomy and strengthening scalability based on the High-Low Mix concept. Recently, drones have been used as a major means in major wars around the world, and there seems to be a good chance that they will evolve into game changers in the future. North Korea has also been making significant efforts to operate reconnaissance and attack drones for a long time. North Korea has recently continued to engage in provocations using drones, and its capabilities are gradually becoming more sophisticated. In addition, with the recent emergence of new strategic Drones, wartime and peacetime threats such as North Korea's use of these to secure surveillance, reconnaissance and early warning capabilities against South Korea and new types of provocations are expected to be strengthened. Through this study, we hope to provide implications by analyzing the capabilities of North Korea's strategic Drones, predicting their operation patterns, and conducting active follow-up research on the establishment of a comprehensive strategy, such as our military's drone deployment and counter-drone system solutions.

This study integrates personality trait theory to empirically Investigate the corporate strategy in Korean venture firms. This study predicts that type A/B, locus of control(internal/external), and risk-taking/avoiding will be positively associated with corporate strategy selection. Corporate strategy selection consists of aggressive entry strategy and defensive niche market strategy. Data obtained from a survey of 87 venture business firms is used to construct final variable measures and test the hypothesized relationships. The statistical result shows that type A, internal, and risk-taking CEOs positively associated with aggressive entry strategy, and type B, external, and risk-avoiding CEOs positively associated with defensive niche market strategy. Additional analysis(multiple regression model) to test relatively importance of independents is used.

Israel craves peace and freedom. Israel has won many wars and conflicts militarily. They have developed strategic thinking based on the data, unique culture, and peacetime preparation system accumulated so far, and the strategic culture based on it contributes to fostering elite strong forces by presenting directions to security strategies.The strategic culture formed by Israeli beliefs, behavioral patterns, and identity influenced strategic thinking and the usefulness of security strategies. The purpose of this study is to redefine the concept of strategic culture by referring to the methodological discussion of strategic culture theory and to examine how useful strategic culture has provided strategic thinking and security strategies. In addition, based on the impact of Israel's strategic culture on security strategy, I would like to present implications for Korea's security strategy.

SDI에서 GPALS로의 전환은 미국의 안보 전략의 변화이자, SDI 계획의 돌파구를 마련하기 위한 시도로 보여진다. GPALS가 표방하는 목표는 소련뿐만 아니라 제3세계 국가들에 의한 고의적, 우발적, 또는 비인가된 미사일 공격에 대해 미국 본토 및 해외 주둔 미군, 그리고 우방국 및 동맹국 등을 방호한다는 것이다. 따라서 GPALS로 인해 SDI는 최초의 논리인 "방호"로 복귀한 셈이다
