This study aimed to explore the parents'intentions of choosing a residential institution as the future alternative for their children with disabilities after the death of a parent, regarding the recent disability service and policy focusing on the deinstitutionalization of services for people with disabilities. For this purpose, the effects of factors relating to the children with disabilities, families and society on the parents' future plans of residential place and guardians are examined. First, parents of children with disabilities are less likely to choose a residential institution as the future living place for their children when their children have a better communication competence, their families are more positive, and their caring burden is lower, compared to others. Second, parents are less likely to choose a residential institution as the future guarding body for their children when their children could communicate well and their families are positive. This result indicated the communication competence of children with disabilities and the positiveness of families are important factors associating with the future plan decision and the additional support for the prevention of institution arrangement after the death of a parent. Findings are discussed in relation to the importance of future plans of residence and guardians for the life of children with disabilities after the death of parents and the implication for social welfare.

This study aims to identify the effects of factors on aggression in adolescents, focusing on the individual, parent, friend factors and SNS usage. In particular, this study is to provide a basis for easing aggression in adolescence by considering the emotional relationship of parents and friends. This study analyzed frequency, t-test, one-way batch distribution analysis(ANOVA), and multi-linear regression, using the data from the 7th year of the Korean Children and Youth Panel Survey. As a result, adolescents who frequently use SNS are more aggressive than adolescents who use less. Among the parental factors, the more abuse and excessive interference were found to be more aggressive, and the higher the coach, the lower the aggressiveness. Furthermore, among the friend factors, it has been shown that the higher the alienation, the more aggressive adolescents are. In order to reduce aggression among adolescents, it is necessary to prepare an integrated program considering the emotional relationship of parents and friends, who are the most influential neighbors, rather than simply restricting the use of SNS.

The overlay multicast that has been recently presented as an alternative for the IP multicast has been getting much attention by the advancement of network techniques to enforce routing in application-levels. In this paper, we verified the efficiency of Internet broadcasting through comparing latency time of TBCP with mOBCP that have distributed Tree-first based spanning-tree structures in overlay multicast techniques. We also propose effective tree structures that minimize latency time and provide competent service by choosing optimum parent nodes early in the base of these two methods over the same time slot in multi-user connection. The results of our comparison showed that average latency time in mOBCP techniques declined by 36% from those of TBCP technique.

Traditional familism and family value is known as the value that most Koreans share with. Strong family solidarity and family-centered perception among Koreans influences other social values and ideology. Under the family value, caring for family members is family responsibility instead of government responsibility. Previous studies argued that the family value played a role to impede the development of family policy in Korea. The aim of this study was to explore a relation between the family value and the needs for care-support family policy. This study investigated how the family value were related to the specific needs for care-support family policy. The data were drawn from the Seoul Families Survey conducted on 2006 by Seoul Women and Family Foundation. The survey data consisted of 2,500 married males and females living in Seoul. The statistical techniques used for analysis were frequencies, means, t-test, ANOVA, crosstabs, multiple regression models, and multinomial logit models. The major findings of this study were as followings. First, while the traditional familism appeared to be held at a certain level, the general attitudes towards cohabitation, divorce, and single-parent family seemed to be less traditional. Second, the familism was found to be partly associated with the needs for the care-support family policy. The respondents who had less traditional value on arriage and child-rearing showed the higher level of needs for daycare center. This finding implied that nontraditional attitudes were related to the needs for an alternative care service such as caring through facilities rather than to the needs for supportive or complementary services. Lastly, the respondents who had higher level of traditional familism showed a higher preference for direct economic service (supportive service) than for other types of service in child care. And the less traditional their attitudes towards marriage and child-rearing, the more likely they are to prefer flexible child care services and programs to other types of child care services. These results implied that the family value was partly influential to family policy. However, it is worthy to note that the family value was related to family policy preference rather than to family policy needs. In other words, traditional family value appeared to influence the types of family policy rather than the level of needs for family policy.

This paper proposes a new authentication protocol for the LR-WPAN. In order to guarantee the reliability and safety of a protocol, this protocol uses the hierarchical authentication approach. In addition, in order to reduce the impact of the denial of service attack, the proposed protocol performs the authentication between a parent router and a joiner device prior to the authentication between a trust center and the joiner device. Moreover, this protocol reduces the authentication delay by decreasing the number of message exchanges during authentication procedure. This paper evaluates the safety of the proposed protocol by the security analysis and reliability of the proposed protocol by the GNY analysis. This paper also compares the number of message exchanges of the ZigBee authentication protocol and the proposed protocol when denial of service attack occurs to evaluate the resistance of the proposed protocol against the denial of service attack. We also analyze the delay for authentication of the joiner device through the implementation of both protocols. Those results show that the proposed protocol effectively protects networks from the denial of service attack and reduces the time for authenticating the joiner device up to maximum 30% as the number of hops increases.
