음성 대화 시스템에서는 사용자가 잘못된 슬롯명을 말하거나 음성인식 오류가 발생해 사용자의 의도에 맞지 않는 응답을 하는 경우가 있다. 이러한 문제를 해결하고자 말뭉치나 사전 데이터를 활용한 질의 교정 방법들이 제안되지만, 이는 지속적으로 사람이 개입하여 데이터를 주입해야하는 한계가 있다. 본 논문에서는 축적된 로그 데이터를 활용하여 사람의 개입 없이 음악 재생에 필요한 슬롯을 교정하는 자기 학습(Self-learning) 기반의 모델을 제안한다. 이 모델은 사용자가 특정 음악을 재생하고자 유사한 질의를 반복하는 상황을 이용하여 비지도 학습 기반으로 학습하고 음악 재생에 실패한 슬롯을 교정한다. 그리고, 학습한 모델 결과의 정확도에 대한 불확실성을 해소하기 위해 질의 슬롯 관계 유사도 모델을 이용하여 교정 결과에 대한 검증을 하고 슬롯 교정 결과에 대한 안정성을 보장한다. 모델 학습을 위한 데이터셋은 사용자가 연속으로 질의한 세션 데이터로부터 추출하며, 음악 재생 슬롯 세션 데이터와 질의 슬롯 관계 유사도 데이터를 각각 구축하여 슬롯 교정 모델과 질의 슬롯 관계 유사도 모델을 학습한다. 교정된 슬롯을 분석한 결과 발음 정보가 유사한 슬롯 뿐만 아니라 의미적인 관계가 있는 슬롯으로도 교정하여 사전 기반 방식보다 다양한 유형의 교정이 가능한 것을 보였다. 3 개월 간 수집된 로그 데이터로 학습한 음악 재생 슬롯 교정 모델은 일주일 동안 반복한 고유 질의 기준, 음악 재생 실패의 12%를 개선하는 성능을 보였다.

This study investigates the employment and spatial mismatch as a significant acting factor of deepening urban poverty and analyses the placeness of regional labor market that the more efficient place-based labor market intervention needs to take into account. The change of unemployment rate as a regional labor market outcome in metropolitan cities is determined by the dynamic interaction between disequilibrium of labor supply and demand and employment mismatch according to various labor market conditions and its process is certainly differentiated across the metropolitan regional labor markets. In addition, it is analyzed that during the employment suburbanization the spatial mismatch puts differentiated impacts on different labor groups through human capital requirements and industry-selective job opportunities. As a result, because this whole process works with its unique process within individual regional labor markets, in order to link between urban poverty and employment mismatch and to promote problem-solving labor market intervention, we need to develop place-based policy based on the placeness of regional labor marekt.

It is difficult to identify attack requests from normal ones when those attacks are based on CSRF which enables an attacker transmit fabricated requests of a trusted user to the website. For the protection against the CSRF, there have been a lot of research efforts including secret token, custom header, proxy, policy model, CAPTCHA, and user reauthentication. There remains, however, incapacitating means and CAPTCHA and user reauthentication incur user inconvenience. In this paper, we propose a method to detect CSRF attacks by analyzing the structure of websites and the usage patterns. Potential victim candidates are selected and website usage patterns according to the structure and usage logs are analyzed. CSRF attacks can be detected by identifying normal usage patterns. Also, the proposed method does not damage users' convenience not like CAPTCHA by requiring user intervention only in case of detecting abnormal requests.

Research on elderly suicide has increased since 2000. It indicates that elderly suicide is receiving a great attention as a part of elderly problems, and policy efforts are needed. However, most of existing research on elderly suicide focused on factors of elderly suicide. Therefore discussion about suicidal prevention measures is staying on general and suggestive level. As a result, this study is trying to seek effective prevention strategies of elderly suicide through systematic analysis of suicidal factors and sporadic policy proposals presented in existing research. To achieve this, the relevant research papers among academic journals registered with Korea Research Foundation are analyzed. According to the results, while the ordinary elderly tended to require macro level of intervention, the potential-risky elderly were inclined to need all of micro and moderate level of prevention efforts. Above all, secondary prevention must be more emphasized in moderate level. In the future direction of research, based on prevention strategies as stated above, it is recommended to entail discussion of what kind of a specific program and policy should be invented and how it should be operated.

The aim of this research is to examine patterns of design governance used by Northern European countries to respond to social crises and understand design governance as a tool for sophistication of social services and social integration. Design governance as applied in Sitra of Finland, MindLab of Denmark and the Gulliver project of Germany encourages using design methodology for analyzing and solving problems related to social phenomena based on involvement of the private, public, industrial, and academic groups. Especially, the citizens are actively involved in developing problem-solving ideas and designing new policy with other governance members, rather than simply providing information or one-time participation. In the cases discussed in this study, design governance reduce unnecessary administrative and financial consumption and inconvenience caused by complicated rules, based on field-oriented approach, regional characteristics, pluralism, and respect for diversity. Therefore, future design policy paradigm will need to evolve into concept of policy design and pluralistic monitoring centered on design governance based on participation of private sector to lead policy development, from the current system in which only few officials decide policy.

This study is aimed to examine the emotional experiences of parents with children who have been sexually abused by others. Five mothers whose child was sexually abused participated in this study. They were first recruited through recommendations made by social welfare agencies that provided services to these children. We conducted two or more in-depth interviews for each mother to collect the data. The mothers' emotional experiences were analyzed using phenomenology. Mothers expressed that they felt like the whole world came crashing down around them, felt "totally lost", and felt deep pain together with their children, such that "my family and I were so devastated". Nevertheless, they gradually came to believe that they could overcome this tragedy by continuously making efforts to protect their children from the dangers outside. Despite their efforts, however, they kept the feeling of "hopelessness, neglect, and their children's wounds", deep inside them. The results indicate that it is necessary to have an intervention for mothers whose child has been sexually abused from a companions' perspective within 10 days after the sexual abuse incident.

In this study, a process of re-creating Jindo Buk Chum, one of the traditional Korean arts, into digital art using various artificial intelligence technologies was proposed. The audience's emotional data, quantified through artificial intelligence language analysis technology, intervenes in various object forms in the projection mapping performance and affects the big story without changing it. If most interactive arts express communication between the performer and the video, this performance becomes a new type of responsive performance that allows the audience to directly communicate with the work, centering on artificial intelligence emotion analysis technology. This starts with 'Chuimsae', a performance that is common only in Korean traditional art, where the audience directly or indirectly intervenes and influences the performance. Based on the emotional information contained in the performer's 'prologue', it is combined with the audience's emotional information and converted into the form of images and particles used in the performance to indirectly participate and change the performance.

The purpose of this study was to examine the relationship of the changes between leisure and social activities, life satisfaction, and happiness of the disabled according to the time before and after COVID-19, and to examine the moderating effect of living alone. For the analysis, the data of 3,773 persons from the employment panel for the disabled were used for the analysis, and as a result of the analysis, it was confirmed that the decrease in leisure and social activities further reinforced the decrease in life satisfaction, and consequently the decrease in happiness also increased. In addition, it was found that the effect of leisure social activities on life satisfaction increases according to living alone. In other words, the decrease in leisure and social activities of the disabled led to a decrease in life satisfaction and decreased happiness. Through these results, although social distancing is important, support such as online gatherings, participation in cultural and artistic activities, and education is necessary as an intervention in reducing leisure and social activities, which can be an important protective factor in the lives of the disabled. Furthermore, it was suggested that screening for mental health and intervention for persons with disabilities living alone are necessary in case management of persons with disabilities.
