네트워크의 광역화와 새로운 공격 유형의 발생으로 침입 탐지 시스템에서 새로운 시퀀스의 추가나 침입탐지 모델 구축의 수동적인 접근부분이 문제가 되고 있다. 특히 기존의 침입탐지 시스템들은 대량의 네트워크 하부구조를 가진 네트워크 정보를 수집 및 분석하는데 있어 각각 전담 시스템들이 담당하고 있다. 따라서 침입탐지 시스템에서 증가하는 많은 양의 감사데이터를 분석하여 다양한 공격 유형들에 대해서 능동적으로 대처할 수 있도록 하는 것이 필요하다. 최근, 침입 탐지 시스템에 데이터 마이닝 기법을 적용하여 능동적인 침입탐지시스템을 구축하고자 하는 연구들이 활발히 이루어지고 있다. 이 논문에서는 대량의 감사 데이터를 정확하고 효율적으로 분석하기 위한 마이닝 시스템을 설계하고 구현한다. 감사데이터는 트랜잭션데이터베이스와는 다른 특성을 가지는 데이터이므로 이를 고려한 마이닝 시스템을 설계하였다. 구현된 마이닝 시스템은 연관규칙 기법을 이용하여 감사데이터 속성간의 연관성을 탐사하고, 빈발 에피소드 기법을 적용하여 주어진 시간 내에서 상호 연관성 있게 발생한 이벤트들을 모음으로써 연속적인 시간간격 내에서 빈번하게 발생하는 사건들의 발견과 알려진 사건에서 시퀀스의 행동을 예측하거나 기술할 수 있는 규칙을 생성한 수 있다. 감사데이터의 마이닝 결과 생성된 규칙들은 능동적인 보안정책을 구축하는데 활용필 수 있다. 또한 데이터양의 감소로 침입 탐지시간을 최소화하는데도 기여한 것이다.

An ICSID award on Lone Star case has been rendered finally on August 31st, 2022 after almost ten years since the Lone Star Funds submitted the request for arbitration against the Republic of Korea in 2012. The Lone Star case is the first investor-state dispute settlement(ISDS) case brought against Korea, and this case, also known as "eat and run" case, has given rise to heated debates for years. Moreover, as the ICSID tribunal has ordered Korea to pay the Lone Star Funds the sum of USD 216.5 million plus interest in the award, this case has become once again the subject of controversy. Any arguments and evidence submitted by the parties in dispute have not been disclosed until recently, however, as the memorials and the award are now open to the public, it has become possible to realize the assertions of each party and the decisions of the tribunal in detail. Therefore, this paper aims at analyzing the main issues of the Lone Star case with a focus on the ICSID award. By examining the substantive and procedural issues of the case one after the other, it might be able to understand the whole picture of the case and prepare for the remaining procedures of this case and other upcoming cases as well.

In April, 1995, ANC government was established in South Africa. The Black government set up Truth and Reconciliation Committee in November, 1995. The Committee investigated approximately 50,000 cases for 3years. Through this process, Black and White in SA could be united into one. Finally, the system of racial discrimination, lasting for about 300 years, was abolished. The Committee played a role as a social infra-structure, which was to perform and solidify democracy in SA. Reconciliation, agreement, Participation, equality, Communication, and Reformation of law system were practically implemented by the Committee. Many people evaluate TRC's activity, which had the reformative and democratic character of the object of investigation, investigative criterion, investigative process, and the approval of investigative result. But De Klerk evaluates that TRC retaliated the White with legal. J. Cronin evaluates that TRC transiently change democracy of the South Africa, and many other social movement groups had a negative view about TRC. But the Black and White in South Africa transformed 'discriminated society' into 'united one'. The Committee took the initiative in such a change. The Committee was not an organization needed for the policy, but the committee was the policy itself to change the former society to the new one. Now The ANC government was forwarding TRC's roles and functions to the truth and reconciliation bureau of the Justice Department for further action. The ANC government has to execute some policy for social reconciliation. Firstly, the government needs to build construction social and national system for making close investigation into the White's historical guilt. Secondly, it must be executed to TRC's recommendation pursuit social reform of social infra-structure in the South Africa. Thirdly, The government should execute policy for the Black's right as labors and social member. Lastly, the government must investigate still-remaining historic state violence and infringement of human right for social reconciliation.

Due to the rapid developments of South Korea, local communities have faced various social pathologies which generated more violent crimes and criminalized younger students. Several horrendous violences, such as a Kangneung Girl assassination assault case in July 2017 and a Busan Girls assault case in September 2017, happened only between young students. This ignited a public uproar and people were more interested in related national policies and voiced for stronger penalties in ways that punish student offenders and abolish the juvenile law. In this respect, various effective policies are needed to prevent the school violence and to eliminate the students' fear of crime. These are expected to create an environment where students could enthusiastically study in a safe environment. Focusing on elementary school students, this study seeks to empirically analyse the effects of their perception of local crime control governance on their fear of crime and, subsequently, to suggest policy implications which could prevent future school violence and juvenile crimes and reduce the students' fear of crime. The results of this study are as follows: First, the analysis of the general fear of local crime control governance and the fear of crime showed that elementary school students' trust in police officers had a significant effect on the general fear. Second, the analysis of the local fear of crime control governance and the fear of crime highlighted that their trust in the police, social ties, intimacy between the police and residents had a significant effect on the specific fear. Therefore, this study is applicable in reality in that it can contribute to the prevention of school violence and reduction of fear of crime by constructing local crime control governance.

기존의 모바일 게임의 경우에는 간단한 스토리를 갖는 2D 게임이 주종을 이루었다. 그러나 이 논문에서는 PC 에서만 가능하다고 여겨지던 3D 경영 시뮬레이션 게임을 모바일에 접목해 보고자 하였다. 시공간의 제약이 없으며 간편성과 이동성을 가진 모바일 게임의 장점을 살리며 3D 게임의 현실감, 시뮬레이션 게임의 재미를 모두 가질 수 있는 게임을 제작하고자 하였다. 게임의 기본적인 줄거리에는 고구려의 역사적 사건을 넣어서 게임을 하면서 고구려의 역사를 직접 느껴보도록 하였다. 세금의 단위나 정책에 관한 내용은 고구려의 실제 역사적 내용을 따랐으며 게임의 중간 중간에 시행되는 고구려의 정책 결정 과정을 통하여 고구려 왕의 생각과 흐름을 느끼도록 하였다. 게이머는 왕을 보조하는 입장에서 고구려의 정책을 간언할 수 있으며 왕의 정책을 지지할 수도, 반대할 수도 있다. 시간의 변화에 따라 왕도 변화하며 왕족의 계도도 고구려의 수순을 따르며, 왕의 역사적인 주요 정책도 게임을 통하여 자연스럽게 적용된다. 이로써 단순한 도시 경영이 주 테마가 아닌 고구려의 역사적 배경을 자연스럽게 삽입한 게임을 제작함으로써 게임의 사실성을 높였으며 한국적인 그래픽과 음악을 삽입하여 통적인 감각을 살렸다. 전본 논문에서는 3D 경영 시뮬레이션 게임 [한고을]의 전체적인 구성과 본 게임의 알고리즘을 소개하고 있다. 본 게임 개발의 가장 큰 목적은 모바일 기반의 3D게임 개발을 통한 사실적인 게임을 제작하고 탄탄한 스토리를 가진 게임 제작이다. 그러나 역사적인 내용을 사용함으로써 부가적으로 교육적인 효과도 있었다. 이 게임개발을 계기로 하여 급속하게 성장하고 있는 모바일 컨텐츠 시장에서도 컨텐츠의 수가 아닌 질적인 증가가 이루어 졌으면 하는 바램을 가진다.

The purpose of this study was to identify factors affecting college-based stress and develop stress-relieving educational programs. Data were collected from 169 students in G-province, from June 15th to july 15th, 2020. Analysis was done using IBM SPSS 21.0 for frequency, percentage, average, standard deviation, t-test, ANOVA, Pearson correlation coefficient, and Multiple regression. College-based stress positively correlated with life event, life event importance, interpersonal emotion, and self-control. The most important factor affecting college-based stress was psychological hardiness (β=-.323, p<.001), followed by club activities (β=.237, p<.001), interpersonal conflict (β=.215, p=.001), grade-2 (β=-.203, p=.001), department adaptation (β=.161, p=.010), and age-21 (β=-.149, p=.024). The explanatory power was 44.4% (F=42.43, p<.001). The results of this study are expected to be used as basic data for the development of educational programs for stress reduction at the university level. Therefore, educational programs considering age and grade, using club activities as support systems, and dealing with psychological hardiness and department adaptation are needed.
