In this paper, we implement the face recognition system to support various ubiquitous sensor network application services using wireless image interface. The proposed system is consist of the H/W such as TX-32CS, the proposed face recognition algorithm using PCA (Principal Components Analysis) and LDPC (Low Density Parity Check). The proposed face recognition systems is inserted in a HOST PC to use the sensor energy effectively. And improve the accuracy of face recognition, we implement a FEC (Forward Error Correction) system. Also, we optimized the simulation coefficient and test environment to effectively remove the wireless channel noises and correcting wireless channel errors. As a result, the face recognition algorithm step is limited 2 times, GAR and FAR are 98.5% and 0.036%.

본 연구는 주양육자의 양육태도와 가정외보호 청소년의 심리사회적 적응(공격성 및 우울.불안) 간의 관계를 자아존중감과 낙인감이 매개하는지를 검증하고, 주양육자의 유형(혈연관계, 비혈연관계)에 따라 그 결과가 차이가 있는지를 알아보기 위해 다집단분석이 수행되었다. 전국의 아동양육시설,그룹홈, 가정위탁지원센터를 통해 표집한 중학교 1-2학년 청소년 430명을 대상으로 수집한 자료를 활용하였다. 구조방정식모형을 통해 분석한 결과,먼저, 자아존중감은 주양육자의 양육태도와 가정외보호 청소년의 공격성 및우울.불안 간의 관계를 유의하게 매개하는 것으로 검증되었고, 낙인감은 유의한 매개효과가 없었다. 둘째, 다집단분석 결과에서는 주양육자와 비혈 연관계인 청소년 집단에서 낙인감이 주양육자의 양육태도와 공격성 간의 관계를 유의하게 매개하였다. 또한 주양육자가 청소년과 비혈연관계일 때양육태도가 자아존중감, 낙인감에 미치는 영향력이 혈연관계인 양육자의 양육태도의 영향력보다 유의하게 크게 나타나, 적어도 가정외보호서비스의 양육태도 측면에서는 ‘피는 물보다 진한 것’이 아닌 것으로 나타났다. 본 연구결과를 바탕으로 가정외보호 청소년의 주양육자 유형을 고려하여 자아존중감 증진 및 낙인감 감소를 통해 가정외보호 청소년의 공격성 및 우울ㆍ불안을 완화할 수 있는 방안을 논하였다. The aim of this study was to examine the mediating effect of self-esteem and stigma on the relationship between the caregiver’s parenting attitudes and psychosocial adjustment(aggression and depression/anxiety) among adolescents in out-of-home care. In addition, we assessed differences in these pathways between the kinship and nonkinship caregiver groups by multi-group analysis. For these purposes, this study recruited 430 adolescents living in residential care facilities, group homes and foster homes by using cluster sampling method. Based on structural equational modeling, the results showed that the relationship between caregiver’s parenting attitude and adolescents’ psychosocial adjustment was significantly mediated by self-esteem, but stigma did not show significant mediating effects. Second, multi-group analysis revealed that there were group differences in the path coefficients of the structure model. In the kinship caregiver’s group, stigma showed a significant mediating effect on the relationship between caregiver’s parenting and adolescents’ aggression. The effects of parenting attitudes of nonkinship caregivers on self-esteem and stigma were significantly greater than those of kinship caregivers, thus at least in the context of out-of-home care it meant that blood is not thicker than water. Based on these results, this study discussed further suggestions to decrease aggression and depression/anxiety of adolescents in out-of-home care, considering the type of caregiver groups.

Purpose: This study was designed to compare physical symptoms and fatigue of hemodialysis patients on dialysis day and non-dialysis day. Methods: Data were collected from 63 outpatients undergoing hemodialysis at a hospital in A university hospital in August and September, 2008 using structured questionnaires. The data were analyzed with SPSS WIN 12.0 program with Paired t-test and Pearson's correlation. Results: Physical symptoms in patients between dialysis day and non-dialysis day were not different statistically (t=1.76, p=.08). Fatigue on dialysis day was higher than on non-dialysis day (t=3.27, p=.00). Physical symptoms and fatigue positively correlated with dialysis day (r=.42, p=.00) and non-dialysis day (r=.52, p=.00). Conclusion: Intervention to decrease physical symptoms and fatigue in dialysis day and non-dialysis day should be developed.
