인공지능 기술의 발전과 함께 자율주행 차량 내 대화형 음성 에이전트(Conversational voice agent, CVA) 시스템이 적극적으로 도입되고 있다. CVA는 음성 사용자 인터페이스(Voice user interface, VUI)를 기반으로 사용자의 명령을 이해하고 정보를 전달하는 기능을 수행하며 최근에는 의인화 기법을 적용하여 사용자와 공감하고 친구처럼 대화할 수 있는 역할로도 그 기능이 확대되고 있다. 의인화 기법의 적용은 그 차원 및 수준에 따라 사용자 경험에 미치는 영향이 다를 수 있다. 특히, 자율주행 상황은 다양한 주행 맥락을 포함하고 있으므로 이에 대한 CVA 의 의인화 적용 연구가 지속적으로 필요하다. 본 연구는 인간 본성(Human nature, HN) 및 음성 특성을 고려하여 CVA 의 의인화 수준을 조작하여 신뢰감과 지각된 의인화에 미치는 영향을 조사하였다. 그 결과 의인화 수준이 신뢰감과 지각된 의인화에 유의한 영향을 미쳤고, 지각된 의인화에서는 HN 특성과 음성 특성 간의 교호작용이 확인되었다. 본 연구는 자율주행 중 급정거 상황에 대해 두 차원의 의인화 수준에 따른 영향을 파악하였다는 점에서 의의를 가진다.

Objectives: This study aims to develop and validate a basic psychological needs satisfaction and frustration scale for school-aged children. Methods: A total of 49 preliminary questions were extracted using the Delphi method. These questions were first composed through pilot studies and a group interview with children. The present study was conducted among students in 4th to 6th grade in elementary school. The data of a total of 455 participants were analyzed through exploratory factor analysis, confirmatory factor analysis, and correlations. Results: The results of factor analysis identified a total of 33 questions constituting 6 factors (autonomy need satisfaction, competence need satisfaction, relationship need satisfaction, autonomy need frustration, competence need frustration, and relationship need frustration). This scale showed a significant correlation with life satisfaction, school adjustment, aggression, and depression variables, which verified the convergent validity. A comparison of the means of basic psychological needs of clinical and nonclinical children showed a significant difference, verifying the discriminant validity of the scale. Finally, the results of calculating internal consistency coefficient and split-halves reliability coefficient showed that the scale was reliable. Conclusions: This study is meaningful, in that it developed a reliable and valid scale to measure the satisfaction and frustration of basic psychological needs, reflecting children’s actual experiences and developmental characteristics.

The aim of this study was to investigate the pitch and formant characteristics of vowels produced by monolingual and bilingual children. We collected sustained phonation of single vowels, /a/, /i/, /u/, from children aged 6 through 10 and compared their acoustic characteristics, fo, F1, F2. Results showed a significant difference between the groups in fo and F1 in the sustained phonation /a/, but not in F2. In the sustained phonation /i/, F2 revealed a significant difference but fo and F1 showed no significant difference. The F2 showed a significant difference in the sustained phonation /u/, but fo and F1 revealed no significant difference between the groups. It is needed to study further on the acoustic characteristics of bilingual children so that we can make a proper language intervention strategy for them.

PURPOSE: Central post-stroke pain (CPSP), a chronic pain condition of stroke patients, can impair activities of daily living and worsen the quality of life (QOL), thereby negatively influencing the rehabilitation process. However, CPSP remains an underestimated complication of stroke. This study aimed to describe the prevalence and types of new-onset chronic pain and to identify the relation between pain and QOL in stroke patients. METHODS: All patients hospitalized because of a diagnosis of stroke were included. Questionnaire was used. Pain intensity was measured using Numerical rating scale (NRS), and pain characteristics were assessed using DN4. QOL was measured using SF-36. Descriptive statistics were used to analyze the characteristics and pain data, and chi-square test was used to compare QOL categorical data between the nociceptive and neurological pain groups. RESULTS: CPSP development was reported by 34% of the post-stroke pain patients. Perceived QOL was low in both groups, especially with respect to the physical functioning, bodily pain, physical-role functioning, emotional-role functioning, and mental health domains. However, no significant difference was observed in QOL between the nociceptive and neurological pain groups (p<.05). CONCLUSION: Our results indicated that CPSP is a common and disabling complication that is difficult to treat, often decreases QOL, and may negatively affect rehabilitation treatment.

PURPOSE: This study was to provide reference data and examine stroke and healty older differences in sit-to-stand test. This study were to determine utility of the 5 repetition sit to stand for discriminating between fallers and non-fallers, identifying an appropriate cutoff score to delineate between the groups. METHODS: Ninety-five participants were recruited. Seventy-two individuals with stroke and twenty-three healthy older agreed to participate in the study. Falls were recorded using a self-administered questionnaire. The 5 repetition sit to stand test measured the time taken to complete t repetitions of the sit to stand maneuver. The time from the initial seated position to the final seated position after completing five stands was the test measure. A cutoff score regarding 5 repetition sit to stand performance in fallers vs. non-fallers, stroke patients vs. healthy older and <60 vs. ≥60 age groups was determined using and ROC curve. RESULTS: Cutoff score of 9.9 seconds were found to be discriminatory between healthy older and subjects with stroke. Cutoff score of 15.5 seconds were found to be discriminatory between fallers and non-fallers. Cutoff score of 18.3 seconds were found to be discriminatory between <60 and ≥60 age groups. CONCLUSION: The 5-repetition sit-to stand test is quick, easily administered measure useful for gross determination of fall risk in people with stroke.

사운드 센서 이용한 Smart 아기 침대의 실시간 모니터링

맞벌이 가구와 육아휴직 사용 비율이 높아지면서 혼자서 육아를 할 때 도움을 주는 제품의 수요가 늘고 있다. 특히 혼자서도 어려움 없이 육아하는 데 도움을 주는 아기침대가 많이 요구되고 있다. 따라서 본 논문에서는 사운드 센서를 사용한 Smart 아기 침대의 실시간 모니터링을 제안하였다. 제안한 침대는 사운드 센서를 이용해 아이의 울음 및 상태를 감지하며, 측정된 센서 출력값은 모바일 어플리케이션으로 확인할 수 있다. 사운드 센서 출력값이 일정 수치 이상일 경우 부모의 목소리로 녹음한 자장가와 같은 음성 파일을 재생시키고, 센서 출력값이 일정 수치 이하일 경우 재생 중인 음성 파일은 정지된다. 만약 센서 출력값이 일정 시간이 지난 후에도 계속 존재하는 경우 모바일 어플리케이션으로 팝업 알림이 간다. 이를 통해 아이는 부모의 녹음된 목소리를 통해 안정감과 편안함을 느껴 빨리 진정할 수 있고, 부모는 실시간으로 아이의 상태를 원격으로 모니터링할 수 있다. As the ratio of double-income households and parental leave use increase, there is an increasing demand for products that help when raising children alone. In particular, there is a lot of demand for baby beds that help raise children without difficulty even by themselves. Therefore, in this paper, we propose a real-time monitoring of a smart crib using a sound sensor. The proposed bed uses a sound sensor to detect the child's crying and condition, and the measured sensor output value can be checked with a mobile application. When the sound sensor output value is more than a certain value, a voice file such as a lullaby recorded with the voice of the parents is played, and if the sensor output value is less than a certain value, the playing voice file is stopped. If the sensor output value continues to exist after a certain period of time, a pop-up notification is sent to the mobile application. This allows the child to quickly calm down with a sense of stability and comfort through the recorded voices of the parents, and the parents can remotely monitor the child's condition in real time.
