An authentic simulation platform for events situated in spatio-temporal space is presented. The authenticity, i.e., logical fidelity to the reality, of this cyberspace is realized by maximizing the diversity and unpredictability of events occurring therein. The knowledge components and associated schemes required for the simulation of events situated in spatio-temporal space encompass the environmental factors, the objects, the events, and their interrelations. We deviled event activation, triggering mechanism, and cognitive function related to event to realize an authentic simulation of discretionary events. The agents in this simulation environments are autonomous in that they have their own existence and capability of event planning. We focused on identifying basic constructs relevant to authentic simulation of discretionary events whose initiation depends on human intention. Several key ideas are implemented in a typical spatio-temporal situation to demonstrate the viability of our simulation mechanism.

In investigating missing persons cases, the focus is on strengthening the efficiency of detectives' work in investigating missing persons cases. Disappearance cases are seen as a problem that directly affects social safety and individual well-being. The research has the following structure. The introduction presents the necessity, scope, and methodology of the study. Next, we analyze the definition, causes, types and actual conditions of disappearance cases. In terms of problems in the process of handling missing persons cases, the initial response process, problems in the response of related agencies after reporting, problems due to the prolongation of the case, and problems due to legal restrictions are analyzed. In the plan to improve the work efficiency of detectives for disappearance cases, the revitalization of public interest investigation networks, strengthening of capacity related to disappearance case investigation, professional public interest detective certification system, and establishment of exception provisions for detective activities are discussed. In the conclusion, we present what is necessary for the activities of public interest detectives specializing in missing persons cases.

This study examined the feasibility of using EEG signals and ERP P3b for extracting video key-frames based on users' cognitive responses. Twenty participants were used to collect EEG signals. This research found that the average amplitude of right parietal lobe is higher than that of left parietal lobe when relevant images were shown to participants; there is a significant difference between the average amplitudes of both parietal lobes. On the other hand, the average amplitude of left parietal lobe in the case of non-relevant images is lower than that in the case of relevant images. Moreover, there is no significant difference between the average amplitudes of both parietal lobes in the case of non-relevant images. Additionally, the latency of MGFP1 and channel coherence can be also used as criteria to extract key-frames.

본 논문에서는 CNN에서 클래스 활성화 맵과 원샷 러닝을 결합하여 트위터 분류를 위한 딥 러닝 모델을 제안한다. 클래스 활성화 맵은 트윗 분류에 대한 분류 주제와 연관된 핵심 어휘를 추출하고 강조 표시하도록 사용되었다. 특히 작은 학습 데이터 셋을 사용하여 다중 클래스 분류의 성능을 향상시키기 위해 원샷 러닝 방법을 적용한다. 제안하는 방법을 검증하기위해 TREC 2018 태스크의 사건 스트림(TREC-IS) 학습데이터를 사용하여 비교실험을 했다. 실험 결과에서 CNN 기본 모델의 정확도는 58.1%이고 제안 방법의 정확도는 69.6%로 성능이 향상됨을 보였다.

본 연구에서는 한국사람이 모국어인 한국어 단어를 산출할 때와 외국어인 영어 단어를 산출할 때 관여하는 대뇌 영역을 fMRI 를 통해 조사하였다. 또한, 단일 언어를 산출할 때와 두 언어를 수시로 바꾸어서 인출할 때 관련되는 뇌 영역이 어디인지를 조사하였다. 실험에 참가한 피험자는 외국어를 공식적인 교육을 통해 12 세 근처에서 배우기 시작한 대학생이었다. 흔히 분류하는 방식으로 late learner로 구분되는 학생들이었다. 한 피험자가 세 종류의 실험 모두에 참여하였다. 피험자의 실험과제는 그림을 보고 그림에 해당되는 이름을 인출하여 말하는 과제였다. 실험 1, 2, 3 모두에서 사건관련 fMRI(event-related fMRI) 기법을 사용하였다. 실험 1에서는 그림을 보고 그림 이름에 해당되는 한국어 어휘와 외래어 어휘를 산출하게 하였다. 언어관련 뇌영역인 Wernicke 영역, Broca 영역, SMA 영역, SMG 영역 등에서 유의미한 활성화가 있었다. 실험 2 에서는 실험 1 에서 사용하지 않았던 그림을 사용하여 그림의 영어 이름과 외래어 이름을 인출하게 하였다. 외국어인 영어 단어를 산출할 때에도 모국어 단어를 산출할 때와 유사한 영역이 활성화되었다. 특히 외래어 산출 시에는 뇌 활성화 영역이 모국어와 영어 단어 산출할 때와 모국어 산출할 때 활성화되는 공통 영역이 활성화되었다. 모국어 산출과 영어 단어 산출의 차이점은 외국어 산출 시에 활성화 영역이 전반적으로 더 컸다는 것과 외국어 단어 산출 시에 Broca 영역보다 조금 밑쪽에서 그리고 모국어 단어 산출시에는 전전두엽 영역에서 더 많은 활성화가 있었다. 실험 3 에서도 실험 1 과 실험 2 에 사용하지 않았던 그림을 사용하였다. 실험 3 의 특이한 결과는 언어 switching 이 있는 경우에 전통적인 언어 영역 활성화 외에 전전두엽의 활성화가 컸다는 것이다. 아마도 언어를 바꾸어 가면서 단어를 산출하는 것이 전전두엽의 정보선택과정에 많은 영향을 주었던 것으로 해석된다. 전체적으로 어휘 산출시에 모국어 어휘, 외국어 어휘, 외래어 등을 산출할 때 공통되는 언어 영역과 언어 특성적 영역이 활성화된다고 결론지을 수 있을 것 같다.

The juvenile delinquency starts from trivial misconduct and reoccurs with the second offense. It is necessary the active plan to reduce the juvenile delinquency. The most important thing in processing the case of law breaking juveniles is to focus on the guidance process rather than punishment process in order encourage them to come back to society as normal members. In this process, I propose the specialist activation, the appropriate confrontation for the first criminals, the necessity for parents education, the mentor's activation, the program development to reduce the juvenile delinquency's second offense rate.

Sex offense by medical practitioners has been occurring continuously in Korea leading to not only patients but the general public expressing anxiety and increased distrust in the medical field. The government has been pushing ahead with the legislation or revision of law to increase the penalties on sexual offenders in response to requests for a stricter legal framework to address sex offense cases and has expressed a strong commitment to actively resorting to administrative corrective measures towards sexually offending medical practitioners. Unlike such an overall social atmosphere, the Judiciary that is in charge of applying the law seems not to perceive the seriousness of sex offense cases committed by medical practitioners. A doctor who had sexually assaulted a middle school female student during medical treatment at a pediatric hospital was found innocent by the supreme court, which was a ruling in direct contrast to overall public sentiment. As such, this study seeks to analyze the precedent on cases involving sex offense by medical practitioners with a focus on the above-mentioned case and present implications. The study seeks to dispel distrust in the overall medical field by addressing the gap in legal interpretation towards sex offense committed by medical practitioners and thus provide basic data that can help the general public receive quality medical services in a safer environment.

Little research has been done to understand the dynamics of well-being among the oldest old, although Korea experiences a rapid increase of this population group. This study explored the effects of demographic characteristics, physical condition, stressful life events and worries on life satisfaction of aged 85 and over. The moderating effects of psychosocial resources in buffering the negative effects of the life events and worries on life satisfaction of this group were also examined. The survey data collected from 213 community residing aged 85 and over was used for analyses. Major findings are as follows. First, most frequent stressors of the oldest old were health related problems. Second, greater worries, higher income status, lower level of physical impairment, co-residence with adult children were significantly related to higher life satisfaction of the oldest old. Third, emotional support from adult children as well as self-esteem of the older persons had buffering effects on the relationship between worries and life satisfaction. According to the results, implications for practice and services to increase life satisfaction of the oldest old were discussed.

There are countless possibilities lying ahead of us, and while predicting the future may be challenging, it does not render the act of forecasting meaningless. Predicting various possibilities allows us to be flexible in coping with unforeseen circumstances. This study was conducted to explore extreme events (X-events) in the population sector in South Korea. To achieve this, focus group interviews were conducted with 32 emergency planning officers in government and public services. Based on these interviews, significant research findings were derived, indicating that population issues such as population decline and aging could have substantial impacts on various fields, including the economy and national defense. With this study as a catalyst, we anticipate a more active discussion and discourse on X-events that could occur in our society.
