Recently, an intelligent product in which information and robotic technologies are applied to an existing common product, called a mother product has been developed. In order to develop intelligent products which could be accepted by users, various intelligent product design methods have been introduced considering various interaction aspects or intelligent parts to be made. However, as an intelligent product is originated in a mother product, intelligent product design methods based on product attributes need to be explored. In this study, the impact of intelligent product types by product attributes on users' acceptance was investigated by comparing hedonic intelligent products and utilitarian intelligent products. An experiment was executed with child slippers as a case. As a result, participants evaluated utilitarian intelligent products more positively than hedonic intelligent products. They showed higher purchase intention and willingness to pay toward utilitarian intelligent products than hedonic intelligent products. In the case of child slippers, even though the hedonic attributes could be expected as they are child products, utilitarian attributes were perceived as much more important than hedonic attributes as the child slippers are related to the floor noise which is a severe social problem.

For complex diseases such as diabetes, hypertension, it is believed that model-free methods might work better because they do not require a precise knowledge of the mode of inheritance controlling the disease trait. This is done by estimating the sharing probabilities that a pair shares zero, one, or two alleles identical by descent(IBD) and has some specific branches of test procedure, i.e., the mean test, the proportion test, and the minmax test. Among them, the minmax test is known to be more robust than others regardless of genetic mode of inheritance in current use. In this study, we compared the power of the methods which are based on minmax test and considering weighting schemes for sib-pairs to analyze sibship data. In simulation result, we found that the method based on Suarez' was more powerful than any others without respect to marker allele frequency, genetic mode of inheritance, sibship size. Also, The power of both Suarez- and Hodge-based methods was higher when marker allele frequency and sibship size were higher, and this result was remarkable in dominant mode of inheritance especially.

is a 1968 western novel by Charles Portis. The novel was adapted for screenplay of the 1969 movie of the same name directed by Henry Hathaway. In 2010, Coen brothers directs, writes, and produces the second adaptation of Portis's novel writing most of the script. Of nineteen films directed by Coen brothers, only and are adapted from novel. (released as in Korea), is the only remake of an existing film by Coen brothers. The story plot of the novel or the 1969 or 2010 do not differ greatly, however by emphasizing on different subjects, the character development is slightly altered and in the end, all three are perceived as unique. By comparing what each story is trying to emphasis, examining different cinematic devices, and how it relates to previous worldviews of modern America seen through Coen brothers, portrays a dark society continuously consuming and while illustrating origin of problematic American society.

This paper is about a case study of two brother talents who have a similar genetic factor The researcher who worked as a teacher of the Institute of Talent Education where the two brothers attended for 3 years analyzed and compared the influential variables through the interview of both the students and their parents. Parents have invested to the elder brother showing geniuses so they disciplined him suppressively out of too much expectation. However, they allowed his brother, who showed talents later, more automaticity, supporting him when he himself wanted to study. As a result, the younger brother showed a more creative thinking ability, and a better school performance This paper is significant in that parents's positive disciplining attitude maximize children's genius.

Extensively used case-control designs in medical studies can also be powerful and efficient for family association studies as long as an analysis method is developed for the evaluation of association between candidate genes and disease. Traditional Cochran-Armitage trend test is devised for independent subjects data, and to apply this trend test to the biologically related siblings one has to take into account the covariance among related family members in order to maintain the correct type I error rate. We propose a more powerful trend test by introducing weights that reflect the number of affected siblings in families for the evaluation of the association of genetic markers related to the disease. An application of our method to a sample family data, in addition to a small-scale simulation, is presented to compare the weighted and unweighted trend tests.

An extensively used approach for family based association test(FBAT) is compared with the sib transmission/disequilibrium test(S-TDT), and in particular the adjusted S-TDT, in which the covariance among related siblings is taken into consideration, can provide a more sensitive test statistic for association. A simulation study comparing the three test statistics demonstrates that the type I error rates of all three tests are larger than the prespecified significance level and the power of the FBAT is lower than those of the other two tests. More detailed studies are required in order to assess the influence of the assumed conditions in FBAT on the efficiency of the test.

This study examined the impact of academic achievement and maternal differential treatment on academic self-concept among adolescent siblings. The sample consisted of 438 students attending middle schools in Seoul (M = 15.2 yrs.), who had a sibling. Data were analyzed using Structural Equation Modeling. Academic achievement compared with a sibling and maternal differential treatment had direct effects on academic self-concept, indicating that children with higher academic achievement scores than their sibling and with perceived maternal differential treatment reported a significantly higher academic self-concept. Also, the relationship between academic achievement as compared with a sibling and academic self-concept was mediated by maternal differential treatment. These findings could be used in educational settings as a basis for improving the academic self-concept of early adolescents.

Objectives：This study was designed to compare the emotional/behavioral characteristics between the siblings of children with autism and normally developing children. Methods：The subjects were 34 children between 10 and 16 years of age, 17 siblings of children with autism, 17 siblings of nonhandicapped children. Both groups performed CDI(Kovacs' Children Depression Inventory), RCMAS(Revised Chidren's Manifest Anxiety Scale), SPPC(Self-Perception Profile for Children), Self-esteem scale. Their mothers performed K-CBCL(Korean -Child Behavior Checklist). The results of those test were analysed by Student's-test. Results：Both social competence and total social competence subsclae scores were significantly lower in sibling group of children with autism than in control group. However, each group was not significantly different on the scores of internalizing symptom, externalizing symptom subscale of CBCL, CDI, RCMAS, Self-Perception Profile and Self-esteem scale. Conclusion : Siblings of children with autism had a lower social competence than normal control group. Group comparisons indicated that siblings of children with autism and normal children did not differ on any self-report measures such as anxiety, depression, self-concept and self-esteem. Further research using more subjects will be needed.

The ordinary least squares regression method of Haseman and Elston(1972) is most widely used in genetic linkage studies for continuous traits of sib pairs. Kruglyak and Lander(1995) suggested a statistic which appears to be a nonparametric counterpart to the Haseman and Elston(1972)'s regression method, but in fact these two methods are quite different. In this paper the relationships between these two methods are described and will be compared by simulation studies. One of the characteristics of the sib-pair linkage study is that the explanatory variable has only three different values and thus dependent variable is heavily replicated in each value of the explanatory variable. We propose a weighted least squares regression method which is more appropriate to this situation and the efficiency of the weighted regression in genetic linkage study was explored with normal and non-normal simulated continuous traits data. Simulation studies demonstrated that the weighted regression is more powerful than other tests.
