The purpose of the study was to analyze the effects of both young children's gender and temperament and their teachers' teaching efficacy and teacher-child interactions on peer play interactions. For this purpose, the data from the 2012 Panel Study on Korean Children were analyzed using analyses of variances and correlation co-efficiencies. In addition, analyses of hierarchical regression, with young children's temperament and teacher-related factors (teaching efficacy and teacher-child interactions) as the independent variables and three sub-factors of peer play interactions (play interaction, play disruption, play disconnection) as the dependent variables, were conducted. The results showed that young children's temperament, teacher efficacy, teacher-child interactions, and peer play interactions differed by gender and significantly correlated. Young children's temperament and teacher-child interactions significantly affected young children's peer play interactions, and the effect of teacher-child interactions was larger than the effect of temperament by 2~2.5 times. The results proved the importance of early childhood teachers' roles in the development of young children's peer interactions with consideration of differences based on children's gender and temperament. With the results given, implications and suggestions for further research were discussed.

The purpose of this study was to investigate the influence of children's elementary school entrance to working conditions of employed mothers. The data from 4th to 8th wave of Panel Study on Korean Children (PSKC) were used for analysis. Specifically, we examined changes in wages, working hours and regular employment of employed mothers after their children entered elementary schools. We adopted Heck selection model for unbalanced panel data after controlling sample selection bias, and compare results of analysis for unbalanced and balanced panel data. The results showed that children's elementary school entrance reduces employed mothers' wage, working hours and regular employment. These results indicate that mother tend to leave regular job and could not entry into decent job when their children are in elementary school.

The purpose of this study was to investigate variables which have an influence on young children's peer interactions. The data of 966 4-year-old children and their parents and class teachers were extracted from the 5th Panel Study on Korean Children in 2012 by Korea Institute of Child Care and Education. The data were analyzed by means of ANOVA, Pearson's coefficient and multiple regression. The results were as follows: First, boys' play disruption and play disconnection were higher than girls', and girls' play interaction was higher than boys'. Second, sociability and activity of temperament, and teacher-child interaction were related to peer disruption. Third, teacher-child interaction and sociability of temperament significantly affected play interaction. Controlling parenting behavior of the mother was positively related to peer interaction in girls. Fourth, teacher-child interaction, sociability and emotionality of temperament significantly affected play disconnection. Social parenting behavior of the father was negatively related to play disconnection in boys. Lastly, teacher-child interaction was the clearest indicator for young children' peer interactions. These findings suggested a potential role of the teacher in young children's peer interactions.

국내에서는 장기 경기침체로 인해 여성들이 창업시장에 도전하는 경우가 많아지고 있으며, 더 나아가 여성창업자들을 위한 민관중심의 창업지원 프로그램이 창업지원센터를 중심으로 시행중에 있다. 본 연구에서는 이러한 여성창업자들이 창업을 통해 성과를 달성하는데 필요한 여러 가지 요인들이 있는데, 개인적인 역량이나 업무적인 역량외에 여성만의 가지고 있는 특징을 독립변수로 선택하여 여성기업의 창업성과를 검증하고자 한다. 여기에 창업기업들에게 정부가 지원하는 정책적인 요인도 조절효과로 추가하여 여성창업자의 창업성과를 조사하였다. 이를 검증하기 위하여 총 250명을 대상으로 설문조사를 실시하였는데 설문에 참여하여 답한 내용중 일부가 누락되었거나 부정확한 표기를 한 설문을 제외하고 실질적으로 총 212명의 여성창업자들을 대상으로 창업성과에 영향을 미치는 요인들에 대한 설문을 통해 결과치를 분석하였다. 분석결과 첫째, 여성창업자 개인의 특성에 따라 창업성과에 (+) 의 영향을 미치는 것으로 나타났다. 둘째, 여성창업자의 업무적 특성인 독창성, 아이디어, 자원분배역량, 지도역량, 네트워크 구축, 인맥확보등이 여성창업자의 창업성과에 모두 정 (+) 의 영향을 미치는 것으로 나타났다. 셋째, 여성창업자만의 특성인 경력단절 유무와 결혼유무에 대해서는 회귀분석을 통한 나타난 결과는 창업성과와 무관하다는 것으로 나타났다. 넷째, 조절효과인 정부의 창업지원정책은 여성의 창업성과에 유의한 영향을 주는 것으로 나타났으나 그 효과가 여성창업자의 다른 독립변수를 능가할 만한 효과로 나타나지는 않아서 정부의 여성창업자에 대한 정책지원이 좀 더 보강되고 확장되어야만 창업의 성과가 더 높아질 수 있음을 시사한 것이다.

This study examined the influences of children's playfulness and teacher-child interactions on their peer interactions, and investigated whether teacher-child interactions had any moderating effects upon the relation between child playfulness and peer interactions. The participants of this study were 240 children in fourth year classes in child care centers in Seoul and Gyoung-gi province and 24 of their teachers. In order to measure the research variables, the Korean version of PIPPS(Pen Interaction Peer Play Scale) by Choi and Shin(2008), the Children's Playfulness Scale(Barnett, 1991), and the modified version of the Caregiver Interaction Scale(Arnett, 1989) were used. The data were analyzed by means of descriptive statics, Pearson's correlations, and hierarchical regression analysis. The results indicated that children's playfulness and teacher-child interactions had significant effects on their peer interactions. Especially, the teacher-child interactions were related to the play disruption and the play disconnection of peer interactions. In addition, teacher-child interactions moderated the effect of children's social spontaneity(children's playfulness) on their play disconnection(peer interactions). The results have some implications for the role of teacher-child interactions in peer play interactions and a range of prevention efforts.

The Household Income and Expenditure Survey is a representative survey of Statistics Korea, which aims to measure and analyze national income and consumption levels and their changes by understanding the current state of household balances. Recently, the disconnection problem in these time series caused by the large-scale reorganization of the survey methods in 2017 and 2019 has become an issue. In this study, we model the characteristics of the time series in the Household Income and Expenditure Survey up to 2016, and use the modeling to compute forecasts for linking the expenditures in 2017 and 2018. In order to evenly reflect the characteristics across all expenditure item series and to reduce the impact of a specific forecast model, we synthesize a total of 8 models such as regression models, time series models, and machine learning techniques. In particular, the noteworthy aspect of this study is that it improves the forecast by using the optimal combination technique that can exactly reflect the hierarchical structure of the Household Income and Expenditure Survey without loss of information as in the top-down or bottom-up methods. As a result of applying the proposed method to forecast expenditure series from 2017 to 2019, it contributed to the recovery of time series linkage and improved the forecast. In addition, it was confirmed that the hierarchical time series forecasts by the optimal combination method make linkage results closer to the actual survey series.

The purpose of this study was to investigate the effects of mothers' parental intelligence on children's peer play interaction and peer acceptance. The participants were 197 fiveyear- old children and their mothers of six kindergartens and child care centers in Seoul and Gyeonggi province. The Penn Interactive Peer Play Scale(Choi & Shin, 2008), the Peer Rating Scale(Asher et al., 1979), and the Parental Intelligence Scale(Hyon, 2004) were used as measurements. The results of this study were as follows. Firstly, the higher scores in mothers' parental intelligence of encouragement, enhancement, rational authoritativeness, acceptance, control, and avoiding rejection roles, the more the children's positive behaviors were exhibited during the peer play. Secondly, children whose mothers provided higher levels in parental intelligence of empathy, encouragement, rational authoritativeness and enhancement roles were rated as displaying higher levels of children's peer acceptance. On the other hand, children whose mothers expressed higher parental intelligence level of the rejection role tended to have lower levels of peer acceptance.

Korea is proceeding to aging society at much faster pace than other countries. To alleviate various problems (health, environment, social relationships, psychology and emotion, and financial problems) of the elderly caused by aging society, there has been increasing attention to social capital. This study investigated types of ways that the elderly at individual level are aware of social capital and the characteristic. In addition, factors that influence the types were studied. Data from 1060 elderly with the age of 65 and older were collected in Korea. Excluding missing data on variables used in the study, data of 960 elderly were used for analyses. K-mean cluster analysis was conducted to investigate types of elderly awareness on social capital at individual level. Multinominal logistic regression was used to find out factors of the types. K-mean cluster analysis resulted in three types of awareness on social capital among the elderly: (1) potential of social capital; (2) severance of social capital; and (3) wealth of social capital. Multinominal logistic regression resulted in that compared to potential of social capital type, when the elderly were younger, inclination of politics was more progressive, they did not have religion, they did not reside in rural, and they did not live in multiplex housing, the elderly were more likely to be in severance of social capital type. Also, when the elderly were women, had higher education and standard of living, were Christian, and did not reside in rural regions. they tended to be in wealth of social capital type. Based on the study results about awareness on social capital among the elderly and factors related to the awareness types, practical and political suggestions that promote social capital to solve problems of the elderly were provided.

This study examined the effects of the online community, such as chatting, book-cafe on the neighborhood relationship. Through a case study of 'The Sharp' apartment area, the characters of neighborhood relationship between user and non-user were compared. The factors affecting the community relationships were analyzed by regression analysis. According to the results, the residents using the online community shared their emotions, thoughts and information with their neighbors so that the level of neighborhood relationship was higher. To reprove the neighborhood relationship being cut off the online community should be handled as an important factor in the planning of apartments. This study as a basic research is expected to contribute to policing against crimes and accidents in apartments.
