Purpose: This study was to examine the fitness of a path model based on the objectification theory and to expand it by including the new variables to explain eating disorder symptomatology (EDS). Methods: The subjects consisted of 444 college women. Data was collected through self-report questionnaires that measured self-objectification (SO), social physique anxiety (SPA) and EDS as the original variables in the objectification theory, and influence of mass media (IMM) and sex-role attitude (SRA) as the new variables. Data was analyzed by SPSS/WIN 12.0 and Amos 5.0 programs. Results: IMM and SRA showed direct effect on SO. IMM had direct and indirect effect on SPA and EDS. SRA had direct and indirect effect on EDS, but only indirect effect on SPA. SO and SPA influenced EDS directly, and SO influenced indirectly EDS. Conclusion: Path analyses indicated support for the original theory and the expanded theory. It is necessary for repeated studies including various age groups of women to clarify the applicability of the objectification theory to Korean women's eating disorders. And it were recommended that we should promote womens' criticism of the image and message about the perfect female body presented in the mass media, and to highlight the relationship of gender equality to women's eating disorders in health education.

This paper aimed at modeling a fine triangular grid for network dome by using Harmony Search (HS) algorithm. For this purpose, an optimization process to find a fine regular triangular mesh on the curved surface was proposed and the analysis program was developed. An objective function was consist of areas and edge's length of each triangular and its standard deviations, and design variables were subject to the upper and lower boundary which was calculated on the nodal connectivity. Triangular network dome model, which was initially consist of randomly irregular triangular mesh, was selected for the target example and the numerical result was analyzed in accordance with the HS parameters. From the analysis results of adopted model, the fitness function has been converged and the optimized triangular grid could be obtained from the initially distorted network dome example.

In this study, we consider the assembly line balancing (ALB) problem which is known as an very important decision dealing with the optimal design of assembly lines. We consider ALB problems with soft constraints which are expected to be fulfilled, however they are not necessarily to be satisfied always and they are difficult to be presented in exact quantitative forms. In previous studies, most researches have dealt with hard constraints which should be satisfied at all time in ALB problems. In this study, we modify the mixed integer programming model of the problem introduced in the existing study where the problem was first considered. Based on the modified model, we propose a new algorithm using the genetic algorithm (GA). In the algorithm, new features like, a mixed initial population selection method composed of the random selection method and the elite solutions of the simple ALB problem, a fitness evaluation method based on achievement ratio are applied. In addition, we select the genetic operators and parameters which are appropriate for the soft assignment constraints through the preliminary tests. From the results of the computational experiments, it is shown that the proposed algorithm generated the solutions with the high achievement ratio of the soft constraints.

This study examines the mediation effect of teacher-child interactions in the process of the impact of teacher's teaching-efficacy on childhood education institutions and classroom environment on peer-play interactions. We used data from 970 children aged between 49 and 55 months and 970 homeroom teachers from the fifth Korean Child Panel (2012) of the Korea Institute of Child Care and Education. The model fitness was excellent after data were statistically analyzed with model of structure to testify the relationship and effect among teaching efficacy, classroom environment, teacher-child interactions, and peer-play interactions. First, the analysis also showed that the teacher's teaching efficacy did not influence peer-play interactions directly, but gave an indirect effect on the peer-play interactions with the mediation of the teacher-child interactions. Second, the classroom environment directly and indirectly influenced the peer-play interactions with the mediation of the teacher-child interactions. Third, the variable of teacher-child interactions was fully effective as a mediating variable in the process of the teaching efficacy and classroom environment influence on teacher-child interactions. Teaching efficacy and classroom environment influenced the peer-play interactions through the mediation of the teacher-child interactions. The significance of mediation effect of the teacher-child interactions was verified through a bootstrapping method.

Phenotypic variation among clones (individuals with identical genes, i.e. isogenic individuals) has been recognized both theoretically and experimentally. We investigate the effects of phenotypic variation on evolutionary dynamics of a population. In a population, the individuals are assumed to be haploid with two genotypes : one genotype shows phenotypic variation and the other does not. We use an individual-based Moran model in which the individuals reproduce according to their fitness values and die at random. The evolutionary dynamics of an individual-based model is formulated in terms of a master equation and is approximated as the Fokker-Planck equation (FPE) and the coupled non-linear stochastic differential equations (SDEs) with multiplicative noise. We first analyze the deterministic part of the SDEs to obtain the fixed points and determine the stability of each fixed point. We find that there is a discrete phase transition in the population distribution when the probability of reproducing the fitter individual is equal to the critical value determined by the stability of the fixed points. Next, we take demographic stochasticity into account and analyze the FPE by eliminating the fast variable to reduce the coupled two-variable FPE to the single-variable FPE. We derive a quasi-stationary distribution of the reduced FPE and predict the fixation probabilities and the mean fixation times to absorbing states. We also carry out numerical simulations in the form of the Gillespie algorithm and find that the results of simulations are consistent with the analytic predictions.

This study examined the fitness of a path model for the relationship among the perceived health status, pain, sleep pattern, and quality of life in the elderly. The data was collected by questionnaires to 276 elderly in J city. The collected data was analyzed using PASW 18.0(win) and AMOS 18.0(win) program. The model fit indices for the hypothetical model were in good agreement with the recommended levels ($x^2$/DF=1.393, p=.077, GFI=.971, TLI=.983, CFI=.989, RMSEA=.038). Based on the constructed model, the quality of life was influenced directly by the perceived health status, pain and sleep pattern, indirectly by the perceived health status and pain. Pain was influenced directly by the perceived health status, and sleep pattern was influenced directly by pain. These results highlight the need for the development of intervention strategies for the promotion of perceived health status in the elderly to improve the quality of life.
