This study examined the mediating effect of self-esteem in the relationship between maternal rejective parenting attitude and children's leadership as well as identified gender differences in the mediating pathways. The mediating effects of this study were examined after controlling the effect of maternal employment status on rejection parenting attitude and the effect of siblings on the children's leadership. Participants consisted of 330 five- and six-year-old children (151 boys and 179 girls) and their mothers. Data analyses included t-tests, F tests, $Scheff{\acute{e}}$ post-hoc tests and Pearson's correlation. Structure equation modeling examined the mediating effect of self-esteem. Bootstrapping method was applied to examine the significance of the mediating effects. Gender differences in the mediating effect were examined through multiple group path analyses. The results of this study were as follows. First, self-esteem mediated the relationship between the maternal rejective parenting attitude on children's leadership. Second, there was a significant gender difference in the mediating pathways with a full mediating effect of self-esteem for boys; however, there was only a partial mediating effect for the girls. This study has implication for investigating gender difference in the mediating mechanism of explaining variance in the leadership of preschoolers. The limitations and more implications of this study are also discussed.

고령자 가구의 급격한 증가는 전 세계적 추세이며 의료비 등 사회적 비용 또한 급격히 증가할 것으로 예상된다. 치매와 같은 노인성 기능 질환의 경우 고령자의 일상생활 활동 (ADL) 패턴을 상시적으로 모니터링하고 평소와 다르거나 비정상적인 패턴이 발생하는 경우 이를 치매 조기진단의 근거로 활용할 수 있다. 그러나 사생활 침해의 우려가 큰 기존의 직접적 센싱 방식과 달리 간접적 센싱 방식 (Non-intrusive approach)을 활용하여 재실자의 최소한의 정보 (Coarse-grained data)만을 수집하고, 이를 통해 활동 정보를 추출하는 연구는 거의 이루어지지 않았다. 또한 추출된 활동 및 활동패턴을 이해하기 위해 활동의 맥락적 정보를 시각화하는 방법 또한 추가적인 연구가 필요하다. 이를 위해 본 연구에서는 재실자의 정보 중 시 공간 데이터 로그만을 활용하여 재실자의 수행 활동을 추출하고 컨텍스트화 된 행동 정보를 공간-활동 지도 (Space-Activity Map)로 시각화한다. 본 연구는 재실자의 일상생활 활동 패턴을 추출하는 데 기반이 되는 연구로서, 향후 고령자를 위한 상시적인 건강 모니터링 기술의 도입에 기여할 수 있다.

The purposes of this study were to analyze and understand the life of mothers rearing children with Down syndrome and to present basic data for overcoming the difficulties of those families. For these purposes, this study made use of the phenomenological analysis and approach with a qualitative research method. The subjects of this study are 4 mothers rearing children with Down syndrome who are beyond school age. The results were as follows. First, the reason why mothers with Down syndrome children went through psychological shock and horror was the social stigma due to the unusual appearance of children with Down syndrome. Second, the isolation with in the public education system was disclosed as a factor causing much sorrow and pain. Through this, we can recognize the importance of ensuring the equal right to receive education of children with Down syndrome. Third, the period which the mother experienced most shock and confusion was right after finding out about the disability that her child has. So, we can identify the importance of early intervention providing psychotherapy and rearing service to the parents. Fourth, the crucial factor that relieved pain and pressure from mothers was social support including family. Therefore, the social support system for mothers with Down syndrome children has to be developed and strengthened. Fifth, the crucial factor that made mother grow up during rearing experience was the reestablishment of cognition about the desired role of mothers. Through this, we can identify the importance of the mental transition process to independent thinking.

This study aims to examine the general tendency of suicidal ideation in single person households and to analyse the differences and effects of related variables(sociodemographic variables, characteristics of single person households, happiness and depression) on suicidal ideation. For achieving these purposes, a survey was conducted using questionnaires, based on quota sampling that considers the distribution of population in each dong of one Gu in Gwangju. Finally, data of 686 single person households were used for analysis. The study findings were as follows. The average score of suicidal ideation in single person households was 6.47 points, it was somewhat higher as compared to prior research that was targeting general households. And the average score of happiness index was 4.17 points, depression was 33.11 points. The level of suicidal ideation in single person households was significantly different according to age, occupation, economic status, health status, period of single life, life satisfaction, and contact with family. In addition, the level of depression(${\beta}=.24$, p<.01) had the biggest effect on suicidal ideation in single person households and it was followed by happiness index(${\beta}=-.19$, p<.05) and family visit(${\beta}=-.15$, p<.05). The total explanatory power was 37%. These findings imply that it is important to find a high mental health risk group and treat it early, because there is a high possibility that single person households might have mental health problems by being isolated or alienated from society. In addition, diverse program and services designed to maintain familial bonds despite family members living separately are needed.

This study was undertaken to invesigate the effect of early nutritional deprivation and environment on neurotransmitter concentrations and behavior in later life. The restoring process of rats fed foods ad libitum after 50% restriction of the casein or the Korean diet during the prenatal and/or the lactating periods was observed. There were two rearing conditions, isolated and enriched, after weaning. Behavioral development was measured by the Y- shaped water maze and the open field test. The neurotransmitters were analyzed after sacrifice at the age of 21 weeks. The results are summarized as follows. 1) The body weight impairment by dietary restriction during the prenatal and lactating periods could be restored within 18 weeks after weaning in case of living in a classical cage. The effect of quantitative restriction was bigger in the Korean diet than in the casein diet. 2) The brain weight was decreased by nutritional deprivation. Environmental enrichment increased it slightly. 3) The concentration of neurotransmitters, norepinephrine, dopamine, and serotonin, were not shown any traces of the dietary restriction at the age of 21 weeks. 4) In the maze test, the deprived rats made more errors than the nourished and the rats fed the Korean diet more than those fed the cascin dict. The environmental enrichment could decrease the number of errors. 5) In the open field test, the dietary deprived groups showed less reaction time, more squares entered in the field, and less number of fecal boli than the nourished among the environmentally isolated rats. However, rats living in the enriched cage without experience of nutritional stress showed the lowest emotionality and the elevated exploratory activity.

This study identifies correlations between the use of media devices, communication ability, and executive function difficulties for third grade students, as well as investigates the moderating effect of a child's communication ability. Data from the 10th (2017) Panel Study on Korean Children [PSKC] was employed (N=557). Descriptive statistics, Pearson's correlation and hierarchical regression were used along with SPSS 25.0(IBM Co., Armonk, NY, USA). The results were as follows. First, the executive function difficulties in the third-grade showed a significant positive correlation with media device use. While also, showing a negative correlation with a child's communication ability. Media devices use and communication ability has a significant negative correlation. Second, a child's communication ability has a moderating effect in relation to the use of media devices and executive function difficulties. The difficulty of executive function showed a reciprocal increase to a child's use of media devices and indicated a discriminatory effect of a child's communication ability. In conclusion, this study shows that communication ability is important as a personal factor for children who control the negative effects of media devices. Therefore, it is necessary to provide and support an environment for the development of a child's communication ability.

본 연구는 기존에 진행되던 시각 장애 인식 개선에 대한 교육 방식의 개선을 위해 VR을 기반으로 시각장애인의 시선과 환경에서 체험을 진행할 수 있는 'Hear me later' VR 콘텐츠를 설계 및 구현하였다. 중고등학생부터 20대 청년까지 타겟의 범위로 하여 비장애인들에게 평범한 일상과 활동이 시각 장애인에게 어느 정도의 불편함을 주는 일상인지를 체험하고 이해할 수 있도록 하기 위해 다음과 같이 콘텐츠를 구성하였다. 한 학생이 아침에 집에서 기상하여 학교에 등교하고, 학교에서 수업을 들은 후, 어두워진 늦은 시간에 집으로 하교하는 흐름으로 각 맵에서는 일상적인 활동이지만, 시각장애인들에게 불편한 활동인 10가지의 퀘스트를 배치하여 사용자들의 참여와 활동을 유도 하였다. 'Hear me later'의 효과를 검증하기 위해 10대~20대 초반 8명의 실험 참가자들을 대상으로 시각장애인에 대한 인식을 체험의 사전 사후 평가를 통해 측정하였다. 그 결과, VR 체험 사후 평가에서 사전 평가에 비해 시각장애인에 대한 인식이 30% 상승하는 결과가 도출 되었다. 특히, 시각장애인에 대한 오해와 편견 부분의 변화가 두드러졌다. 본 연구를 통해, 시공간의 구축이 자유롭고 체험을 극대화할 수 있는 VR기반의 장애 체험 교육 프로그램의 가능성을 검증 하였고, 이를 다양한 분야로 확대할 수 있는 기반을 마련하였다.
