Purpose: The purposes of the study were to determine the effects of AIDS education which includes discussion on knowledge, prejudice, social interaction, and intention for AIDS prevention in college students. Method: A convenience sampling method was used to collect data, and 136 university students participated in the study. One group pretest-post test design was used and questionnaire for measuring knowledge about AIDS and attitude to AIDS were administered before and after 100 minutes of AIDS education, The education program consisted of a 50-minute lecture with video aids and 50 minutes of small group discussion. Means, SD, and paired t-test with the SPSS program were used to analyze the data. Results: There were significant increases in knowledge(p= .000) and social interaction(p= .002) after the education, but no significant changes in prejudice(p= .832) nor in intention for AIDS prevention(p= .074). Conclusion: AIDS education including discussion was found to be an effective method for improving knowledge and social interaction of college students. The results suggest that education which includes discussion sessions should be used with college students to improve social interaction with people who are HIV positive and enhance knowledge about AIDS.

The purpose of the present study was to examine the trajectories of children's negative emotionality and mother's social parenting over a 3-year period (for children at ages 1-3) and to then analyze the bidirectional effects between the two variables. The longitudinal casual relationship among children's negative emotionality, mother's social parenting and peer interaction at age 3 was also examined. The data, taken from the Panel Study on Korean Children, were analyzed using latent growth modeling. The results were as follows. First, the level of negative emotionality was seen to have increased by 2 years of age, whereas the level of mother's social parenting decreased by this point. Second, higher initial negative emotionality predicted decreases in mother's social parenting, However, higher initial mother's social parenting predicted increases in children's negative emotionality. The initial level and slope of mothers' positive parenting predicted peer interaction at age 3, while only the slope of negative emotionality predicted peer interaction. These findings suggest that temperament and parenting predict changes in each other and peer interaction.

Purpose: The purpose of this study was to investigate the effect of career decision self-efficacy on major satisfaction among nursing students, and to examine the moderating effect of professor-student interaction on career decision self-efficacy and major satisfaction. Methods: This study analyzed the data of 307 students among fourth-year university nursing students in A and C cities from May 2017 to July 2017 using the SPSS 24.0 statistics program. Results: There were significantly positive relationships between career decision self-efficacy, major satisfaction, and professor-student interaction. The professor-student interaction showed moderating effects in the relationship between career decision self-efficacy and major satisfaction, with 52.7% of explanatory power. Conclusion: This finding suggests the importance of career decision self-efficacy and the moderating effects of professor-student interaction to increase nursing students' satisfaction in their major. Therefore, it is necessary to make diverse efforts in the field of education to improve students' career decision self-efficacy and professor-student interaction.

The purpose of this study was to examine mothers' ideal and actual parenting behaviors toward their infants in three parenting domains; social, didactic, and limit setting. A total of 264 mothers of young children under age three from Seoul, Korea completed Parental Style Questionnaires (PSQ). Mothers' self report on their ideal and actual parenting were explored as a function of child sex, age, and birth order. As expected, there were significant differences between mothers' ideal and actual behaviors in all three parenting domains: Mothers' ideal behaviors such as social interaction, didactic interaction and limit setting were higher than those of their actual behaviors. For mothers' ideal parenting, results revealed neither significant main effects nor interaction effects. However, the Parenting Domain x Birth-Order 2-way interaction and the Parenting Domain x Child Age 2-way interaction were significant for mothers' actual behaviors. Specifically, mothers reported more social and didactic behaviors with their first-born than later born children, but not for limit setting behavior. It was also found that higher limit setting behaviors were apparent for their 2- and 3-year-old than 1-year old children whereas lower social interactions were found for 3-year-old than for 1-year-old. In light of universality and uniqueness, mothers' parenting behavior toward young children has been discussed.

In the authors' previous study, an axial force-flexural moment (P-M) interaction curve model was proposed to evaluate fire-resisting performances of reinforced concrete (RC) column members. The proposed method appeared to properly consider the axial and flexural strength degradations including the secondary moment effects in RC columns due to fire damage. However, the detailed P-M interaction curve model proposed in the authors' previous study requires somewhat complex computational procedures and iterative calculations, which makes it difficult to be used for practical design in its current form. Thus, the aim of this study was to develop a simplified P-M interaction curve model of RC columns exposed to fire considering the effects of fire damage on the material performances and magnitudes of secondary moments. The simplified P-M interaction model proposed in this study was verified using 66 column fire test results collected from literature, and the verification results showed that the proposed simplified method can provide an adequate analysis accuracy of the failure loads and fire-resisting times of the RC column specimens.

In this study, the program to investigate the multiple body interaction effects between a floating platform and a shuttle tanker considering the coupled effect of hull (FPSO) with mooring lines and risers was developed. The coupled analysis program, which is called WINPOST-MULT using the hydrodynamic analysis results by WAMIT, was made. For the verification of WINPOST-MULT by means of numerical experiments, two multiple-body models of an FPSO-FPSO and an FPSO-shuttle tanker system are adopted. With the FPSO-FPSO model and a two-mass-spring system to idealize two identical bodies for the 100-year storm wave condition in GOM, the numerical simulations were performed to investigate the interaction effects between two identical bodies. For the more reality, the coupled analysis for the FPSO-shuttle tanker model in the tandem arrangement was carried out in the consideration of the environmental condition of the West Africa Sea as a rather mild condition. Through the case studies with interaction effect and without interaction effect by the iteration method and the combined method, it is verified that the program is a very useful tool for the analysis of the interaction problem of multiple-body system and the coupled problem of the hull/mooring/riser.

The purpose of this study was to examine the effects of interaction based mother-child art therapy on the change of child and mother's interactions in a child who was in trouble due to attachment problems. The subject in this study was a six-year-old child who faced difficulties in peer relationship building and who were maladjusted to kindergarten because of unstable attachment and negative feedback from his parents. Also, he showed serious problem behaviors at home. The ABA design was adopted among single-subject research designs, and the Target child was observed in the sessions in terms of the subfactors of Marschak's Behavioral Rating Scale to gather data related to the changes of child and mother's interactions. As a result of analyzing the collected data, there were positive changes in all the subfactors that were the child's verbal/nonverbal interactions, the mother's verbal/nonverbal interactions and mother-child interactions. Therefore the interaction based mother-child art therapy that was designed to boost child and mother's interactions was effective at furthering the mother-child interactions of the child with attachment problems.

This paper presents a novel analytical formulation for the analysis of composite beams with partial shear interaction stiffened by a bolted longitudinal plate accounting for time effects, such as creep and shrinkage. The model is derived by means of the principle of virtual work using a displacement-based formulation. The particularity of this approach is that the partial interaction behaviour is assumed to exist between the top slab and the joist as well as between the joist and the bolted longitudinal stiffening plate, therefore leading to a three-layered structural representation. For this purpose, a novel finite element is derived and presented. Its accuracy is validated based on short-and long-term analyses for the particular cases of full shear interaction and partial shear interaction of two layers for which solutions in closed form are available in the literature. A parametric study is carried out considering different stiffening arrangements to investigate the influence on the short-and long-term behaviour of the composite beam of the shear connection stiffness between the concrete slab and the steel joist, the stiffness of the plate-to-beam connection, the properties of the longitudinal plate and the concrete properties. The values of the deflection obtained from the finite element simulations are compared against those calculated using the effective flexural rigidity in accordance with EC5 guidelines for the behaviour of elastic multi-layered beams with flexible connection and it is shown how the latter well predicts the structural response. The proposed numerical examples highlight the ease of use of the proposed approach in determining the effectiveness of different retrofitting solutions at service conditions.

The objective of present study is to understand the interaction of burning droplets in air stream for various droplet arrangement. The unsteady combustion of linearly arranged droplets with a convective flow has been studied numerically. The droplets with spacing of $5R_0\;to\;40R_0$ horizontally and with spacing of $4R_0\;to\;16R_0$ vertically are studied. The effects of Reynolds number, horizontal spacing, and vertical spacing on the interaction of burning droplets are examined. The results indicate that the droplet burning behavior is influenced by Reynolds number and relative location of droplets in the array. The interaction of droplets is increased for arrays with smaller droplet spacing. The vaporization of droplets in the array is varied with both horizontal and vertical spacing exponentially.

The purpose of this study was to explore the effects of mother-child interaction and child's social behaviors on child's peer acceptance. Participants were 108 4- to 5-year-old preschoolers(58 boys, 50 girls) and their mothers. Data were analyzed by descriptive statistics, correlation analysis and stepwise multiple regression analysis. The major findings are summarized as follows: (1) mother-child interaction are generally correlated with child's peer acceptance. And child's prosocial behavior was positively correlated with child's peer acceptance, whereas child's aggressive behavior, asocial behavior and hyperactive-distractible behavior were negatively correlated with child's peer acceptance. (2) The most influential factor on child's peer acceptance was child's experience in session, the next influential factor was child's hyperactive-distractible behavior and the last influential factor was asocial behavior.
