This study has verified the process of helping actors recognize their sexual problems linked to sexual violence cases through early sexual experience history, and exploring and insighting the stuck feelings of sexual violence actors through psychodrama, which focuses on expressing behavior and emotions. The research questions were divided into sexual violence cases and perceptions of actors, actual insights through psychodrama, and dealt with past biblical history related to actors' events and events, exploration of childhood trauma, and insights and changes in emotions through psychodrama. The results from the study are as follows. First, they showed low self-understanding levels and frequent use of defense mechanisms against sexual violence cases in an environment related to cases involving sexual offenders, and were aware of the problematic factors affecting the cases in the course of their daily lives, but did not take them seriously. Second, there were many distorted masculinity and adult sites related to participants' biblical experience history. In the early experience of sexual activity, it was often viewed as a sexual object rather than an emotional exchange with a lover, and the contents of the initial Bible experience were linked to actual sexual violence cases committed by participants. Third, childhood trauma of participants through psychodrama led to rapidly changing family circumstances and abuse by fathers. Fourth, the actual content of emotions represented by anger in the early stages of psychodrama is meaningful in that it revealed the process of sadness, pain, regret and longing for a departing mother leading to objective insight into emotions through the catharsis process.

Cyber Kill Chain is derived from Kill chain of traditional military terms. Kill chain means "a continuous and cyclical process from detection to destruction of military targets requiring destruction, or dividing it into several distinct actions." The kill chain has evolved the existing operational procedures to effectively deal with time-limited emergency targets that require immediate response due to changes in location and increased risk, such as nuclear weapons and missiles. It began with the military concept of incapacitating the attacker's intended purpose by preventing it from functioning at any one stage of the process of reaching it. Thus the basic concept of the cyber kill chain is that the attack performed by a cyber attacker consists of each stage, and the cyber attacker can achieve the attack goal only when each stage is successfully performed, and from a defense point of view, each stage is detailed. It is believed that if a response procedure is prepared and responded, the chain of attacks is broken, and the attack of the attacker can be neutralized or delayed. Also, from the point of view of an attack, if a specific response procedure is prepared at each stage, the chain of attacks can be successful and the target of the attack can be neutralized. The cyber command and control system is a system that is applied to both defense and attack, and should present defensive countermeasures and offensive countermeasures to neutralize the enemy's kill chain during defense, and each step-by-step procedure to neutralize the enemy when attacking. Therefore, thist paper proposed a cyber kill chain model from the perspective of defense and attack of the cyber command and control system, and also researched and presented the threat classification/analysis/prediction framework of the cyber command and control system from the defense aspect

이 논문은 제도적 관점에서 미국의 위성산업 사례를 통하여 복잡한 제품시스템(CoPS)의 공진화 과정을 살펴본다. 이는 공진화의 자세한 기술이라기보다는 그것의 주요 특징들을 이해하는 작업니다. 위성산업은 수출통제제도와 상호작용하며 국가안보와 산업경쟁력을 둘러싼 경쟁적인 입장들이 대립하는 상태에 있다. 역사적 제도주의와 행위자중심 제도주의 관점에서 미국 위성산업 사례를 분석해 보면, 냉전이후 미국의 위성산업과 제도의 경로는 지속적으로 산업경쟁력 지향 속에서 제도 도전자와 방어자들의 상호 대립적이면서도 타협적인 제도수정의 결과물이다. 결과적으로 국가안보의 제도 규칙은 변경되었으며, 이는 냉전이후 위성산업의 시장화의 경로를 다지는데 기여하였다.

A method for estimating the effectiveness of each protective action against a nuclear accident has been proposed using the fuzzy set theory. In most of the existing countermeasure models in actions under radiological emergencies, the large variety of possible features is simplified by a number of rough assumptions. During this simplification procedure, a lot of information is lost which results in much uncertainty concerning the output of the countermeasure model. Furthermore, different assumptions should be used for different sites to consider the site specific conditions. Tn this study, the diversity of each variable related to protective action has been modelled by the linguistic variable. The effectiveness of sheltering and evacuation has been estimated using the proposed method. The potential advantage of the proposed method is in reducing the loss of information by incorporating the opinions of experts and by introducing the linguistic variables which represent the site specific conditions.

Purpose: This study aimed to identify the influencing factors that affect the radiation protection behavior of nurses, by applying the educational diagnostic stage of the PRECEDE Model. Methods: Participants were 167 nurses working in interventional procedure rooms and operating rooms in general hospitals and university hospitals in Korea. Data were collected from August 30 to September 25, 2019, through self-reporting questionnaires and analyzed with t-test, ANOVA, Pearson's correlation coefficients, and hierarchical multiple regression analysis using the SPSS/WIN 25.0 program. Results: The influencing factor that affects nurses' radiation protection behavior was the radiation protection environment (β=.41, p<.001), accounting for 59.6% of the radiation protection behavior (F=17.34, p<.001). Conclusion: Administrative and financial efforts to create a safe organizational atmosphere and establish a safe radiation protection environment are needed. Moreover, it is necessary to develop guidelines for nursing work in radiology to improve radiation protection behavior and reduce nurses' radiation exposure.

정보화 시대의 도래와 함께 원자력발전소 등 사회 간접자본의 중요 시설에서 운영되는 각종 장치들 역시 디지털화되면서 기존에 존재하지 않았던 사이버 공격에 대한 위협이 현실화되고 있다. 이러한 중요 사회 간접자본 등의 운영에 위협을 가하는 행위는 사회적으로 경제적으로 매우 큰 재난을 발생시킬 수 있기 때문에 공격 발생 이전에 사전 방어 체계를 구축해야 하는데, 이때, 실질적으로 위협이 되는 취약점의 존재 여부를 사전 인지하는 것이 매우 중요하다. 이를 위하여 본 논문에서는 원자력발전소의 계측제어계통에서 운영되는 국산화된 디지털 장치에 대하여 관련 취약점을 확인하고 확인된 취약점의 실질적인 위험도를 장치의 운영환경 특징을 반영하여 도출하며, 주요 기기의 운영 규제지침의 준수 여부를 점검하는 도구의 개발 결과를 소개한다. 본 논문은 원자력발전소 상에서 운영되는 시스템을 주요 대상으로 작성되었다.

악성코드는 매년 그 수가 증가하고 있으며, 악성코드의 공격기법이 지능적이고 복합적으로 진화함에 따라 이에 대한 분석과 대응이 요구된다. 하지만 일부 악성코드는 감염여부를 숨기기 위하여 분석에 대한 회피방법으로 루트킷을 통하여 방어자에 의한 악성코드의 코드 분석을 우회함으로써 은폐된 상태로 악의적인 공격을 수행한다. 따라서 본 논문에서는 유저레벨에서 IAT(Import Address Table)의 정보를 후킹하여 악성 행위를 수행하는 루트킷을 탐지하는 대응방안을 제안한다.

Four cargo ships were ambushed by bombs in 2019 while navigating in the Strait of Hormuz. It was not clear who attacked those ships, however, many nations including the United States argued that it was Iran due to several reasons. The United States established the maritime collective defense system named International Maritime Security Construct (IMSC) in order to protect the maritime security in the Strait of Hormuz, without disclosure against whom it is aimed. Persian, who uses the Persian language unlike other countries in the Middle East, is the major ethnic group in Iran, and most of them believe Shi'ah Islam while most of the Arabs in the Gulf countries adhere to Sunni Islam. It seems that historic and religious motives caused the bipolar system in the Middle East, however, it is plausible to analyze the system of international affairs in the Middle East via defensive or structural realism. Iran has attempted to maintain its hegemony in the region by supporting Shi'ah muslims in the neighboring countries as well as in the world by using military and economic means. In this context, Iran's maritime strategy is to maintain its maritime hegemony on the Persian Gulf via countering threats and cooperating with friendly navies by using the Islamic Republic of Iran Navy(IRIN) and the Islamic Revolutionary Guard Corps Navy(IRGCN). IRIN acts like other navies in the world: protecting national interest at sea, expending its operational areas to the outer seas, and enhancing cooperation with other navies. Meanwhile, IRGCN plays a role as an asymmetric force at sea. It is composed of small and fast asymmetric assets, which can ambush ships fast and furious. Considering the poor study for Iran's maritime strategy in Korea, analyzing the strategy is meaningful for the Republic of Korea Navy, which has operated the Cheonghae Unit for more than ten years since it has extended its operational area over the Strait of Hormuz. In order not to be drawn into the conflict in the Strait, research on the maritime strategy of Iran and other countries in the Middle East should be started.

To establish an effective performance appraisal system, ratee accountability is essential because it increases the likelihood of meaningful utilization of performance appraisal feedback. In the context of a multi-rater performance appraisal system, this study examines the effect of the ratee general accountability and accountability to the supervisor and peers on the ratee's intention to change behavior based on the performance appraisal feedback. This study further explored the moderating effect of perceived feedback specificity on the relationship between the ratee accountability and behavioral change intention. Hierarchical multiple regression analysis was conducted using the survey data from 153 employees in eight firms with multi-rater performance appraisal systems. The results showed that ratee general accountability was positively associated with the intention to change behavior. Furthermore, perceived feedback specificity attenuated the positive relationship between the ratee general accountability and behavioral change intention, which was the opposite of the hypothesized direction. The findings indicate the importance of managing and facilitating ratee accountability for implementing a multi-rater performance appraisal system. The result also emphasizes the critical role that performance appraisal feedback plays in motivating performance improvement by providing flexible, constructive advice and behavioral change strategies instead of inducing self-defense or justification.
