Purpose: This study was done to determine whether a parenting education program using responsive teaching strategies is effective for parenting stress, maternal interactional behavior and behavioral problems in children at risk for Attention Deficit Hyperactivity Disorder (ADHD). Methods: Participants in this study were 17 elementary school children and their parents. The ADHD risk group was determined by scores on the Korean-ADHD Rating Scale. The parenting education program was developed based on Dr. Mahoney's responsive teaching curriculum. Mothers participated in the program once a week for 8 sessions. Treatment outcome was evaluated using the Korean version of the Child Behavior CheckList (K-CBCL), parenting stress, maternal interactional behavior, and child pivotal developmental behavior. Data were analyzed using Wilcoxon signed rank test, Mann-Whitney test, and regression analysis. Results: After the parenting education program, no significant difference in parenting stress (Z=-1.00, p=.320) was found, but there was a significant decrease in the child's internal behavior problems (Z=-2.05, p=.040), and also a significant improvement in maternal interactional behavior and a significant difference in child pivotal developmental behavior (Z=-2.67, p=.008). Conclusion: The results indicate that parenting education programs based on responsive teaching strategies are effective and that application of a program is recommended to prevent behavioral problems and improve maternal child interaction for children at risk for ADHD.

성인기의 양극성장애와 정신분열병 환자에서 아동기에 주의력결핍-과다활동 증상을 조사하여 서로의 연관성을 알아보고자 하였다. 저자들은 40세 미만의 남자 중 원주기독병원에서 추적진료중인 26명의 양극성장애군, 29명의 정신분열병군, 그리고 27명의 정상대조군에서 Wender Utah Rating Scale(WURS), WURS 25개 항목(WURS-25), Parent Rating Scale(PRS)을 이용하여 아동기의 주의력결핍-과다활동 증상을 비교하였다. 양극성장애군은 정상대조군과 비교하여 WURS의 평균득점이 의미있게 높았다. WURS-25와 PRS의 평균득점도 양극성장애군이 다른 두 군에 비해 의미있게 높았다. 그러나 정신분열병군에서 WURS, WURS-25, PRS 각각의 평균 득점은 정상대조군과 유의한 차이가 없었다. WURS와 PRS는 양극성장애군과 정상대조군에서 상관관계를 보였지만 정신분열병군에서는 상관관계가 없었다. 양극성장애군에서 정신분열병군과 정상대조군에 비해 아동기의 주의력결핍-과다활동 증상이 더 많았으며, 이 결과는 양극성장애와 주의력결핍-과다활동장애의 연관성을 시사한다.

Purpose: This study aimed to investigate the impact of family resilience on caregiver well-being across various age groups of children diagnosed with ADHD (attention-deficit/hyperactivity disorder) groups (0-5, 6-11, and 12-17 years). Methods: Utilizing secondary data from the 2022 US National Survey of Child Health, this cross-sectional study involved 2,752 children who were formally diagnosed with ADHD. Statistical analysis included descriptive analysis, Spearman's rank correlation, chi-square tests, and linear regression, conducted using SPSS version 27. Results: The study revealed a moderate positive correlation (r=.35, p<.001) between family resilience and caregiver well-being. Controlling for covariates, family resilience accounted for 25.2%, 21.1%, and 22.1% of caregiver well-being variance in age groups 0-5, 6-11, and 12-17 years, respectively. Additionally, factors like employment status, family structure, and caregiver age showed varying influences on caregiver well-being across these developmental stages. A consistent pattern emerged across these age groups: unemployment and non-traditional family structures were associated with negative impacts on caregiver well-being, whereas older caregiver age positively influenced well-being. Conclusion: This research underscores the importance of age-specific family resilience strategies to improve caregiver well-being and family interactions in ADHD contexts. Investigating these aspects through qualitative studies across various cultures could deepen our understanding of well-being and inform culturally sensitive interventions.

Poisson's ratio is one of elastic constants of elastic solids. However, it has not attracted attention due to its narrow range and difficult measurement. Transverse wave velocity as well as longitudinal wave velocity should be measured for nondestructive measurement of Poisson's ratio. Hard couplant for transverse wave prevents transducer from scanning over specimen. In the present work, a novel measurement of Poisson's ratio distribution was proposed. Immersion method was employed for the scanning over the specimen. Echo signals of normal beam longitudinal wave were collected. Transverse wave modes generated by mode conversion were identified. From transit time of longitudinal and transverse waves, Poisson's ratio can be determined without information of specimen thickness. This technique was demonstrated for aluminum and steel specimens.

The purpose of this study is to analyze elementary teachers' science class objectively and quantitatively using Mobile Eye Tracker. The mobile eye tracker is easy to wear in eyeglasses form. And experiments are collected in video form, so it is very useful for realizing objective data of teacher's class situation in real time. Participants in the study were 2 elementary teachers, and they are teaching sixth grade science in Seoul. Participants took a 40-minute class wearing a mobile eye tracker. Eye movements of participants were collected at 60 Hz, and the collected eye movement data were analyzed using SMI BeGaze 3.7. In this study, the area related to the class was set as the area of interest, we analyzed the visual occupancy of teachers. In addition, we analyzed the linguistic interaction between teacher and students. The results of the study are as follows. First, we analyze the visual occupancy of meaningful areas in teaching-learning activities by class stage. Second, the analysis of eye movements when teachers interacted with students showed that teacher A had a high percentage of students' faces, while teacher B had a high visual occupation in areas not related to classes. Third, the linguistic interaction of the participants were analyzed. Analysis areas include questions, attention-focused language, elementary science teaching terminology, daily interaction, humor, and unnecessary words. This study shows that it is possible to analyze elementary science class objectively and quantitatively through analysis of visual occupancy using mobile eye tracking. In addition, it is expected that teachers' visual attention in teaching activities can be used as an index to analyze the form of language interaction.

This study investigates the life of Benjamin Hobson(合信, 1816.1.2-1873.2.13)-the writer of five books of western medicine which influenced the establish of "ShinGiCheonHeom(身機踐驗)"-in order to expand our base to study "ShinGiCheonHeom". Findings and results of the investigation are as follows. 1. Treatise on Physiology("全體新論") excited a deeper interest among the Chinese literati and was so eagerly sought after that a reprint of it was made for sale. The income of works of Hobson's probably excited a deeper interest among the Korean literati also. 2. We found Hobson had written many works. Among those we must pay attention to A Medical Vocabulary in English and Chinese("醫學英華字釋"). Through this book we can reach agreeable translation of "ShinGiCheonHeom". 3. Evangelism and philanthropism promoted activities of Hobson as a doctor and as a an introducer of western medicine. But ignorance of oriental medicine-Hobson thought medical science in China was at a low level-lied in these activities and passion to do it. Nowadays we must wipe out thought of this way through the scientific way.

Objectives: Children with attention-deficit hyperactivity disorder(ADHD) often have difficulties in social behavior. The aim of this study was to evaluate the effectiveness of a short-term training program for improving social skills, self-perception and attention deficits. Methods: The subjects were nine children diagnosed with ADHD with(or without) other mental disorders using the Diagnostic Interview Schedule for Children(DISC-ADHD) module. Children were given eight sessions of a social skills training program. Parents of children simultaneously participated in their own training which was designed to support their children's generalization of skills. Assessments included child, parent and teacher ratings of social skills, self-perception and attention deficit at baseline and post-treatment. Results: Social skills training led to significant improvements in child-reported measures of self-esteem, in teacher reported measures of social skills, and in parent-reported measures of attention deficit. Conclusion: This study suggests that short-term social skills training programs for children with ADHD may improve their social skills, self-perception and attention deficits.

Objective : This study aimed to investigate the associations of anxiety symptoms with behavior and attention in elementary school children with attention-deficit/hyperactivity disorder (ADHD). Methods : A total of 195 elementary school children with ADHD participated in the study. The Korean Version of ADHD Rating Scale (K-ARS) and Behavior Assessment System for Children(BASC-2) were used to measure the children's behavior. Anxiety and attention was assessed with State-Trait Anxiety Inventory for Children (STAIC) and ADHD Diagnostic System (ADS), respectively. Children with ADHD were categorized to two groups of ADHD with low anxiety (ADHD-LA) and ADHD with high anxiety (ADHD-HA) according to the total STAIC scores. Scores on K-ARS, BASC-2 and ADS were compared between two groups of ADHD-LA and ADHD-HA. Results : The Scores on K-ARS total and both subscales in ADHD-HA group were significantly higher than ADHD-LA group. Scores on the BASC-2 subscales including hyperactivity, aggression, conduct problem, anxiety, depression, somatization, withdrawal, attention problems were also significantly higher in ADHD-HA group compared to ADHD-LA group. In contrary, scores on ADS subscales were not significantly different between the both groups. Conclusion : Our study identified that the anxiety accompanied with ADHD was associated with the negative behavioral aspect in children with ADHD. However, the performances on attention task were not affected by the anxiety comorbid with ADHD. Future studies to reveal underlying mechanism are needed for further understanding the association with anxiety and ADHD.

본 연구에서는 ADHD의 원인론에 대한 다양한 신경학적 이론들을 살펴본 후, ADHD 진단에 널리 사용되는 신경심리학적 평가방법들에 대한 국내, 외 연구결과들을 고찰하였다. ADHD 아동들이 여러 주의력 검사상에서 일관성있게 경계력, 지속적 주의력, 주의산만성, 주의력의 분할과 조절에 문제를 보이고 있고, 실행 능력과 작동기억외에 연합기억에서도 어려움을 보이는 것으로 나타났다. 이러한 신경심리학적 검사결과는 ADHD 아동이 전두엽외에 망상활성체계 등 두뇌의 여러 부위를 포함하는 신경망에 장애가 있을 가능성을 시사해주는 것으로 생각된다. 그러나 국내에서 ADHD 아동들에게 널리 사용되고 있는 신경심리검사들은 대부분 외국에서 제작된 것이므로, ADHD 아동들의 수행결과를 보다 정확하게 비교하고 해석하기 위해서는 ADHD와 정상 아동, 그리고 기타 소아정신과장애 아동들을 대상으로 그러한 신경심리검사들에 대한 연령별 규준 확립과 타당도 검증을 위한 한국 표준화연구가 조만간 이루어져야 하겠다.

Direct methanol fuel cells(DMFCs) are receiving significant attention in the portable power source and electric vehicular transportation because of its high energy efficiency as liquid fuel, low cost, and no requirement of fuel reforming process. In this study, we synthesized the Sulfonated poly(ether ether ketone) (SPEEK) to evaluate the possibility of use as a proton exchange membrane for DMFC. And poly(vinylidienedifluoride) (PVDF) was used to increase proton conductivity in SPEEK and simultaneously to prevent methanol transport through the cross linked membrane. Furthermore, in order to improve the electrical composite properties for DMFC applications.
