The purpose of this study was to identify the effects of parent-child relationship perceived by university students on value of marriage and partner selection criteria. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, parent-child relationship, value of marriage and partner selection criteria. To analysis the data, t-test, ANOVA, and two step cluster analysis was used. The female group A with passive parent-child relationship had high level of negative value of marriage, male group D with active parent-child relationship had high level of romantic and instrumental value of marriage. The male and female passive group considered external condition as a partner selection criteria more than male and female active group does. As a partner selection criteria, passive male group recognized internal condition more than passive and active female group does. and active female group recognized situational condition more than passive male group does. This study reveals that university students' parent-child relationship does have an effect on their value of marriage and partner selection criteria. It is therefore proposed that diversify objectives and education content of family life education should relate not only to individuals' value of marriage but also to their parent-child relationship.

In this paper, we devise a cost function by considering the energy consumption rate and the remaining energy of a peer. Then, we propose a parent peer selection method that chooses the least cost peer in the system in a distributed manner. On the contrary to the conventional method that makes each peer select the least cost neighbor as a parent peer, the proposed method chooses a parent peer using the swarm intelligence formed among a set of peers. Therefore, the proposed method could extent distributedly the number of peers searched for parent peer selection. Thus, compared to the conventional method, the proposed method increases the probability of being a parent peer as the cost of a peer becomes smaller with less operational load.

In this paper, we consider inner inheritance of parent objects to their child objects in SR DEVS. The inheritance process of function is implemented by the inside inheritance function when the inherited parent object is determined. In the inside inheritance, the integrity and fragment inheritance can be divided as th asset property. Also, the function process is requested when the inheritance selection in th inheritance is occurred to several assets. The child object can receive assets from the parent object through the determination method of selection function to the inside inheritance.

Objective: The purpose of this study is to gain basic information for parental education by investigating parent's implementation and perception of children's right to play. Methods: The subjects of this study were 458 parents who have a child in kindergarten or 1st grade of elementary school in J city. The research tool used in this study, the Parent's Perception of and Implementation for Children's Right to Play(PPICRP), was developed by researchers. PPICRP is a 5type rating scale questionnaire which includes the selection of a space for play, play time, play mate, instrument, etc. The data were analyzed by using the SPSS 18.0 program. Results: The results showed that the parent's implementation for children's right to play was lower than the parent's perception of it except for the selection of play instrument. Conclusion/Implications: The results of this study imply that there is a need for parent education which contains concepts and stresses the importance of play, which implement children's right to play. The unexpected result in the play instrument, the excessive organization of the play by adults, and the difference of parent's implementation according to the gender of their children were further discussed.

In this paper, we propose a distributed parent peer selection method to construct an efficient peer-to-peer(P2P) network topology by considering the capacity of a peer and the hop distance from a data source to the peer. To achieve this goal, we propose a method to combine the two performance metrics to calculate the probability that a peer becomes a parent peer. Using the probability, we propose a method to select a parent peer stochastically by making use of the state information of the neighboring peers that each peer maintains. Through simulation studies, we show that the proposed method drives high capacity peers to support more children peers and makes the diameter of the P2P network shorter than the other methods.

In recent years, there has been a proliferation of consumer health information available on the internet related to parent-child health. More and more, parents are accessing information about child ca re through the Internet and computer at home. But there is no guarantee that the information is current, unbiased, or accurate. Several researchers have suggested some criteria for evaluating internet sites; source, accuracy, disclosure, currency, accessibility. As more consumer search the World Wide Web for parenting information, nurses have to learn more about this technology. Because nurses can assist parents in identifying how to locate information they can trust. It is also needed to for nurses to document the criteria for information selection on internet and to evaluate outcome of cyberspace intervention of parenting.

The purpose of this study was to identify needs of mothers in order to lay a foundation for improving the content of parent education in early childhood educational institutions. The mothers of 164 kindergarten children in Pusan participated in this study by a questionnaire developed by the researchers. Conclusions were that the felt needs of mothers identified in this study should be included in parent education programs along with knowledge, skills and attitudes selected by professionals. Selection of content should be based on the fact that most mothers have similar concerns and interest in raising their children, regardless of background. However, mother's educational level needs to be considered. Further study needs to be done on educational methods, and tentative models of parent education need to be designed in order to activate effective parent education.

In order to elucidate the mechanism which regulates the production of cyclodextrin glucanotransferase (CGTase) and to achieve overproduction of CGTase by releasing catabolite (glucose) repression, several catabolite repression resistant mutants were selected from newly screened Bacillus firmus var. alkalophilus H609, after NTG (N-methyl-N -nitro-N-nitrosoguanidine) treatment, using 2-deoxyglucose as a nonmetabolizable analog of catabolite glucose and as a selection marker. Five catabolite repression resistant mutants were selected from about 30, 000 2-deoxyglucose resistant colonies. Relative catabolite repression indices of the selected mutants were in the range of 8~80% assuming 100% for parent strain. The amount of CGTase produced by the mutant strain CR41, which was 250 units/ml, was three times larger than that produced by its parent strain. The mutation seems to have occurred in the regulatory region of CGTase gene and not in the structural region or the glucose transporting system in cell membrane. The enzymatic properties of CGTase excreted from parent and mutant strains were also compared.

Bacterial leaf pustule (BLP) caused by Xanthomonas axonopodis pv. glycines is a serious disease to make pustule and chlorotic haloes in soybean [Glycine max (L). Merr.]. While inheritance mode and map positions of the BLP resistance gene, rxp are known, no sequence information of the gene was reported. In this study, we made five near isogenic lines (NILs) from separate backcrosses (BCs) of BLP-susceptible Hwangkeumkong $\times$ BLP-resistant SS2-2 (HS) and BLP-susceptible Taekwangkong$\times$ SS2-2 (TS) through foreground and background selection based on the four-stage selection strategy. First, 15 BC individuals were selected through foreground selection using the simple sequence repeat (SSR) markers Satt486 and Satt372 flanking the rxp gene. Among them, 11 BC plants showed the BLP-resistant response. The HS and TS lines chosen in foreground selection were again screened by background selection using 118 and 90 SSR markers across all chromosomes, respectively. Eventually, five individuals showing greater than 90% recurrent parent genome content were selected in both HS and TS lines. These NILs will be a unique biological material to characterize the rxp gene.

Beta-carotene producing transformants were produced in the background of 'Nagdongbyeo', a Japonica rice cultivar. Introgression of the carotenoid locus in the transformant, PAC4-2 into the elite cultivar 'Ilpumbyeo' was started. To initiate a backcrossing program, we surveyed 220 SSR markers and found that 38% of them were polymorphic between 'Ilpumbyeo' as a recurrent parent and the PAC4-2 as a recipient parent. The selection strategy comprising foreground and background selection was employed. First, foreground selection was practiced in $BC_1$, $BC_2$, and $BC_3$ generations using the transgene specific PCR-based marker in addition to visual scoring of the seed color. Marker-based background selection combined with phenotypic selection was employed from $BC_3F_2$ to $BC_3F_4$ generations. Blast search indicated that the transgene PAC4-2 was located between SSR markers, RM6 and RM482. 240 $BC_3F_3$ and 63 $BC_3F_4$ lines were evaluated for four agronomic traits including days to heading. Most of the lines were similar to Ilpumbyeo in agronomic traits evaluated. The percentage of PAC4-2 genome ranged from 4% to 21% with a mean of 12.5%, which was higher than the expected for an unselected $BC_3$ backcross population. This could be explained by the fact that two genes for beta-carotene and the stripe virus resistance were targeted in this study. We selected 10 representative $BC_3F_5$ lines from 63 $BC_3F_4$ lines based on agronomic traits and carotenoids content. The selection strategy would be appropriate for the introgression of beta-carotene gene in a breeding program.
