The purpose of this paper is to analyze the behavior of North Korea's cyber attack against South Korea since 2009 based on major international security theories and suggest South Korea's policy option. For this purpose, this paper applied the behavioral domain and characteristics of 'cyber power' and 'coercion dynamics' model, which are attracting attention in international security studies. The types of cyber attacks from North Korea are classified into the following categories: power-based incarceration, leadership attacks and intrusions, military operations interference, and social anxiety and confusion. In terms of types and means of cyber power, North Korean GPS disturbance, the Ministry of Defense server hacking and EMP are hard power with high retaliation and threat and cyber money cashing and ransomware are analyzed by force in the act of persuasion and incentive in the point of robbing or asking for a large amount of money with software pawns. North Korea 's cyber attack has the character of escape from realistic sanctions based on the second nuclear test. It is important for South Korea to clearly recognize that the aggressive cyberpower of North Korea is changing in its methods and capabilities, and to ensure that North Korea's actions result in far greater losses than can be achieved. To do this, it is necessary to strengthen the cyber security and competence to simultaneously attack and defend through institutional supplement and new establishment such as cyber psychological warfare, EMP attack preparation, and enhancement of security expertise against hacking.

For many years, emotions have been regarded as dangerous as well as obstructive to reason and rationality. Even in the history of dramatic genres based on human behavior, emotions are often portrayed as errors or flaws that lead to the collapse of characters, even though they are presented as powerful motives to evoke the characters' actions. Based on the development of the cognitive science field today, it is revealed how emotion is important for human thinking, judgment and action, and how closely reason and emotion are combined. This study examines emotions dealt with in drama genres on the basis of the sociality of emotions. Emotions also play a crucial role in the change and judgment of the audience of drama. This study examines the sociality of emotions and looks at the social aspect of individual emotions through the movie as a text. Just as horror movies attempt to communicate using and expanding feelings of fear, the movie uses the emotions of 'Sad' and 'Losing' to try to expand and share it. And I look into the mechanism in which the emotions of the characters in drama are transmitted to the audience in the form of empathy.

With the rapid development of block chain technology, attempts have been made to put the block chain technology into practical use in various fields such as finance and logistics, and also in the public sector where data integrity is very important. Defense Operations In addition, strengthening security and ensuring complete integrity of the command communication network is crucial for operational operation under the network-centered operational environment (NCOE). For this purpose, it is necessary to construct a command communication network applying the block chain network. However, the block chain technology up to now can not solve the security issues such as the 51% attack. In particular, the Practical Byzantine fault tolerance (PBFT) algorithm which is now widely used in blockchain, does not have a penalty factor for nodes that behave maliciously, and there is a problem of failure to make a consensus even if malicious nodes are more than 33% of all nodes. In this paper, we propose a Adaptive Consensus Bound PBFT (ACB-PBFT) algorithm that incorporates a penalty mechanism for anomalous behavior by combining the Trust model to improve the security of the PBFT, which is the main agreement algorithm of the blockchain.

The purpose of this study is to understand the adjustment process of families adopting an older child, and to generate a substantial theory. To achieve this purpose, we conducted in-depth interviews with mothers adopting an older child and analyzed data with qualitative analysis approach. From the analysis, theoretical model has been made, and the model includes the adoptive families' diverse experiences, barriers to adjustment as well as resources and strategies that they mobilized and used for smooth adjustment. Their experiences in the process of adjustment consisted of five phases: unfamiliar meeting, shock, fighting alone without support, control, and stability. Barriers to adjustment process were composed of adoptees' problem behaviors, loss of time, lack of preparation, lack of experiences, repetition of the vicious circle, withstanding alone, improper resources, lack of support, and being criticized. Resources and strategies that families adopting an older child utilized were individual resources and ability such as rearing experiences, intellectual ability, willingness, belief, and perspective change; family system such as spouse and other offsprings; informal support system such as extended families, relatives, friends, neighbors, and other families adopting an older child; formal resources such as adoption workers and helping professionals. From our results, we suggested policy and practice guidelines to help adjustment experiences for families adopting an older child.

This study aims to understand the status of mandatory military service planning and career barrier recognition as well as to analyze the difference between how students perceive mandatory military service as a potential barrier to their future careers(career barrier recognition) and career preparation behavior by the mandatory military service planning level among male college students. For the purpose, inquiries for the subject were set up as follows. 1. What are the levels of mandatory military service planning and career barrier recognition? 2. Is there a difference in career barrier recognition depending on the level of mandatory military service planning? 3. Is there a difference in career preparation behaviour depending on the level of mandatory military service planning? This study found out the level of mandatory military service, military barrier recognition and career preparation behavior of 284 male students from 4 universities in Daejeon and Chungnam area. Along with that, descriptive statistic, correlation analysis and t-test were conducted with SPSS 17.0 program The results of this study are as follows: First, 79.2% of male students have higher mandatory military service planning than the average value. Meanwhile, considering 3 sub-factors of mandatory military service planning, the ratio of those with high scores in practicality is lower than importance and concreteness. Based on this, it is assumable that they have a low perception for practical and concrete behaviors such as data collection in mandatory military service planning, which indicates their awareness has not developed into concrete behaviors even though they recognize the importance of planning. Also 73.9% of male students responded higher career barrier recognition than the average value shows that they recognize mandatory military service as a barrier relatively highly. Especially, those who answered "Very much" (7 scores) for every inquiry in career barrier recognition accounted for 16.9%, which forms the biggest group. and considering the response by each inquiry, it is ascertained that they consider the absence by mandatory military service time or military service as the biggest difficulty. Second, the difference in career barrier recognition between the top 30% and bottom 30% of mandatory military service planning is not statistically significant. However, in terms of importance and the sub-factor of mandatory military service planning, a significant inter-group difference in career barrier recognition is shown. In other words, to join the military is recognized as an obstacle in their career barrier recognition regardless of the mandatory military service planning level. Also, a group which considers the importance of the mandatory military service planning highly recognizes the military as the bigger obstacle compared to the other groups which are not considered in this way. Third, the difference in career barrier recognition between the top 30% and the bottom 30% of the mandatory military service planning is statistically significant. The need of mandatory military service planning is marked by the fact that those with a high level of mandatory military service planning show stronger career barrier recognition than those without plans. Through the study, the need of mandatory military service planning is suggested to both male students and career consultants considering the mandatory military service from a perspective of career based on Korean reality. Also, as precedent studies on pre-inducted men can be hardly found currently, this study is significant in accumulating empirical data about mandatory military service, a unique characteristic of the Korean career development process.

This study examined the effects of emotional content on the encoding process of emotional stimuli and the effects of emotional context on those of neutral stimuli. It was examined whether the superior memory of emotional stimuli is due to attentional resource allocation. This study were performed an emotional picture and a neutral word were presented in succession at every trials. The results of recognition judgement showed superior memory of emotional pictures than neutral pictures, but showed poorer memory of neutral words in emotional context than those in neutral context. LPC(Late Positive Complex) of ERP results showed the similar pattern: higher amplitude by emotional pictures than neutral pictures, and lower amplitude by neutral words in emotional context than those in neutral context. This result is considered to support attention allocation hypothesis.

Child abuse often interferes with the normal and healthy development of a child, bringing about various complications and problematic behaviors. Furthermore, such physical, mental abuse or neglect, and sexual abuse on a developing child may have serious effects even until after adolescence. The types of injuries caused by physical abuse vary, but some types of injuries are common. A great number of them can be detected during a routine dental examination because many of these injuries are present in the facial and dental region. Accordingly, in the case of abused children, it is important to find the signs of abuse through regular dental checkups, as many suffer injuries to the face, head and neck area including the oral and perioral area. As a pediatric dentist, it is the legal and social obligation to contribute to preventing and assisting the struggle against child abuse. The authors contemplate ways for all pediatric dental related personnel to find some clinical signs and symptoms of child abuse to help early detection, and to manage the situation properly.

우리 사회는 정보화와 다원화로 빠르게 변화하고 있다. 경제현상도 변화하고 마케팅의 기법도 다기해지고 있다. 네트워크마케팅(NWM)이란 다단계마케팅(MLM)과 통용되는 개념으로 직접마케팅(Direct Marketing) 기법 중의 하나로 비교적 새로운 유통방법이다. 피라미드와 혼동되어 한 때 비판의 대상이었던 네트워크 마케팅이 실정법에 근거한 새로운 경제활동의 하나로 국민경제에 기능하게 되었다. 올바른 네트워크 마케팅과 실정법에 대한 이해가 필요하며 경제활동의 하나인 이 분야에도 하나님의 주권과 방법이 실현될 필요가 있다. 이 사업에 참여한 성도들은 주님의 피로 사신 교회의 목적에 충실한 행동과 성숙한 신앙인의 자세와 태도로 임할 필요가 있다. 무엇보다도 자신의 재정적 능력범위에서 사업에 참여하는 것이 바람직하다. 일확천금이나 일시에 거금을 번다는 사실과 다른 선전에 현혹되지 말고 자기 자금이나 적정수준의 자본금으로 사업에 참여하는 것이 요구된다. 현행 방문판매법은 교사나 공무원 등의 우월적 지위를 이용하여 상대방에게 다단계 판매를 강요하는 것을 금지하고 있다. 교회에서도 교회 본래의 목적인 복음 전파와 예배 등의 활동과 상치되거나 방해해서는 곤란할 것이다. 자기의 구원과 삶이 바로 서고 이웃을 돌아보아 사랑을 실천하며 복음을 전파하고, 살아서 하나님의 나라를 이 땅에 구현하고 죽어 천국에서 주님과 함께하는 성숙한 신앙생활에 근거해야 할 것이다. 교회도 네트워크마케팅에 대한 바른 이해가 필요하며, 관련 교리에 대한 정확한 이해와 적용이 요구된다고 할 수 있다. 네트워크마케팅에 대한 실정법이 제정되어 있고 현실에 맞게 수차례 개정되어 오고 있으므로 이에 대한 바른 이해가 요청된다. 또한 과학의 발전에 중세의 교회가 이해를 새롭게 한 것처럼, 경제 현상의 변화에 대해서도 통전적인 이해가 요구된다. 이 세상은 근본적으로 하나님이 창조한 세상이기 때문에 이 세상 자체를 악하다고 볼 수 없고 더구나 구원을 이 세상에서의 이탈로 볼 수 없다. 진정한 구원이란 원래 하나님이 보시기에 아름다웠던 그 세상으로의 회복을 포함한다. 이런 면에서 하나님 주권 신앙 하에서 구원이란 전 인격적인 구원, 전 우주적인 구원이 된다. 그렇기 때문에 성도는 세상의 삶과 학문, 예술, 정치, 경제, 사회를 포함한 모든 분야를 하나님의 뜻 가운데서 그 원래의 목적에 부합할 수 있도록 회복시키는 일에 적극 참여해야 한다.

The purpose of this study was to investigate the effect of vocal and instrumental background music on a verbal memorizing task. Participants were 30 undergraduate and graduate students and were randomly divided into two groups. All participants in both groups took a pretest and a posttest to examine the improvement of the memorization. Background music was inserted during the memorization task. Subjects in Group A listened to a vocal recording whereas Group B listened to the same music except with a cello playing the melody of the vocal part. All participants were asked to take the posttest to examine the improvement of their knowledge after the memorization. The t-test was used to compare the two groups. Results indicated that Group A(8.93) exhibited higher mean scores than Group B(7.46) but there were no significant differences t(28) = 1.38, p < .05. This study implies that lyrics does not distract word memorization and background music does not influence cognition directly.
