This study aims to analyze the mutual influences between adolescents' multicultural acceptability and school adjustment. Research problems for research are as follows. First, is multicultural acceptability and school adjustment stable over time? Second, what is the longitudinal impact of school adjustment on multicultural acceptability over time? Third, what is the longitudinal impact of multicultural acceptability on school adjustment over time? The results of analyzing the research problems by applying the autoregressive cross-lagged model are as follows. First, the autoregressive model of school adjustment has a significant effect on the future time point and is stable over time. Second, the autoregressive model of multicultural acceptability have a significant effect on the future time point and is stable over time. Third, cross-lagged effect from school adjustment to multicultural acceptability has a statistically significant effect on the multicultural acceptability at a later time, and is stable over time. Fourth, cross-lagged effect from multicultural acceptability to school adjustment was not statistically significant at the time of multicultural acceptability, and there was no change with time. This study is meaningful to provide the theoretical and practical implications by verifying the influence of the three - year term data over time.

The purpose of this study was to investigate the differences in children's daily experience and school adjustment of elementary school according to children's gender and self-care and to explore the relationship between children's daily experience and school adjustment. Data were collected from the NYPI panel survey of 2010. The data were analyzed by means of Cronbach's ${\alpha}$ tests, means, standard deviations, Two-way ANOVAs, and Pearson's Correlation. The results of this study were as follows : 1. There were some significant differences by gender and self-care in daily experience. Girls spent more time in watching TV but less time in games than boys. And self-care children spent less time in learning and reading, but more time in game and TV watching. Also there was a interaction effect of learning experience by gender and self-care. 2. There were some significant differences by gender and self-care in school adjustment. Girls showed more positive school adjustment than boys. And children who are cared for by their parents showed more positive learning and school rule adjustment. 3. There were some significant relationship between children's daily experience and school adjustment.

Objectives: This longitudinal study was done to identify the relationship of school adjustment and sponsor support or future time perspective and the differences of these 3 variables between 1st and 2nd survey of children having Didimseed account in institutional care. Methods: Participants were 25 elementary fourth to sixth grade children who are living on one facility that located in G. metropolitan area at 1st survey and 2nd survey was done at five-year intervals. Data were collected from September 2012 to September 2017 and were analyzed using t-test, paired t-test, ANOVA, post-hoc test and Pearson's correlation coefficients. Results: The level of school adjustment knowledge was not different significantly according to grade, gender and admission period at 1st survey. At 2nd survey, the level of school adjustment was different significantly according to grade only. The level of school adjustment was associated with positive future time perspective(r=.74) and negative future time perspective(r=-.54) at 1st survey, and that was associated with negative future time perspective(r=-.49) and meeting frequency of sponsor(r=-.43) at 2nd survey. There were not significantly different school adjustment and future time perspective variables between both surveys. But meeting frequency of sponsor at 2nd survey was lower significantly than that at 1st survey. Conclusions: Based on the results of this study, it would be necessary to prepare the policies that could have their positive future time perspective to increase school adjustment of institutionalized children. Also the effective strategies to increase not only Didimseed account support but emotional support through qualified meeting with sponsors should be developed.

The seasonal adjustment is an essential process in analyzing the time series of economy and business. One of the powerful adjustment methods is X11-ARIMA Model which is popularly used in Korea. This method was delivered from Canada. However, this model has been developed to be appropriate for Canadian and American environment. Therefore, we need to review whether the X11-ARIMA Model could be used properly in Korea. In this study, we have applied the method to the annual sales of refrigerator sales in A electronic company. We appreciated the adjustment by result analyzing the time series components such as seasonal component, trend-cycle component, and irregular component, with the proposed method. Additionally, in order to improve the result of seasonal adjusted time series, we suggest the demand forecasting method base on autocorrelation and seasonality with the X11-ARIMA PROC.

In this paper, a dynamic backoff adjustment method of IEEE 802.15.4 is proposed for time-critical sporadic data in a noisy factory environment. For this, a superframe of IEEE 802.15.4 is applied to a real-time mixed data (periodic data, sporadic data, and non real-time message) transmission in factory communication systems. To guarantee a channel access of real-time sporadic(non-periodic) data, a transmission method using the dynamic backoff is applied to wireless control networks. For the real-time property, different initial BE, CW parameters are used for the dynamic backoff adjustment method. The simulat-ion results show an enhancement of the real-time performance of sporadic emergency data. The proposed method provides the channel access of real-time sporadic data efficiently, and guarantee real-time transmission simultaneously within a limite-d timeframe.

본 연구는 탈북청소년 교육 종단연구 3-5차년도 자료를 사용하여 탈북청소년의 사회자본과 학교적응의 변화 및 그 관계를 종단적으로 분석하고자 수행되었다. 잠재성장모형 분석을 실시한 결과, 탈북청소년의 사회자본이나 학교적응은 고정된 것이 아니라 시간의 경과와 함께 변화하는 것으로 드러났다. 이 같은 변화에서 뚜렷한 평균적인 흐름은 발견되지 않았으나 변화의 개인차는 존재하는 것으로 파악되었다. 한편 탈북청소년의 초기 사회자본은 당시의 학교적응에는 영향을 미치지만, 학교적응의 변화에까지 지속적으로 영향을 주지는 않는 것으로 확인되었다. 탈북청소년의 학교적응 변화는 그들의 사회자본이 어떻게 달라지는지에 의해 영향을 받는 것으로 밝혀졌다. 이러한 결과는 탈북청소년의 사회자본을 강화시킴으로써 그들의 학교적응 수준도 점진적으로 개선시킬 수 있는 여지가 있음을 시사한다.

The seasonal adjustment is an essential process in analyzing the time series of economy and business. There are various methods to adjust seasonal effect such as moving average, extrapolation, smoothing and X11. One of the powerful adjustment methods is X11-ARIMA Model which is popularly used in Korea. This method was delivered from Canada. However, this model has been developed to be appropriate for Canadian and American environment. Therefore, we need to review whether the Xl1-ARIMA Model could be used properly in Korea. In this study, we have applied the method to the annual sales of refrigerator sales in A electronic company. We appreciated the adjustment by result analyzing the time series components such as seasonal component, trend-cycle component, and irregular component, with the proposed method.

월별 시계열은 일별 시계열의 월별 합이지만, 일별 시계열을 대체로 관측할 수 없어서 요일구성변동, 명절·공휴일변동 등 달력변동을 가상적으로 가정한 가변수를 포함한 RegARIMIA 모형을 이용하여 추정하고 있다. 일별 시계열을 관측할 수 있다면 요일구성변동, 명절·공휴일변동 등 달력변동을 일별 시계열을 바탕으로 추정할 수 있고 이를 이용하여 월별 시계열의 계절조정을 개선할 수 있다. 이 논문에서는 일별 시계열의 달력변동 추정을 이용하여 월별 시계열의 계절조정을 개선하는 방법을 제안하고, 이 방법을 적용하여 3개의 월별 시계열을 계절조정하고 기존의 X-13ARIMA-SEATS를 이용한 계절조정과 비교하였다.

Fathering practices were assessed by the modified version of the fathering Practices Scale while children's social adjustment was assessed by the Social Adjustment Scale in this study of 405 first to sixth grade children and their fathers. Fathering practices differed by father's age, education, occupation, amount of time with children, extent of participation in children's school activities, mother's job status, and children's birth order. Children's social adjustment varied by father's education, amount of time with children, and participation in children's school activities. There were correlations among all four factors of children's social adjustment and all eight factors of fathering practices. Father's responsibility for children was the strongest predictor of children's social adjustment.
