This study explored the effects of emotional intelligence and sense of humor in institutionalized and at-home children on their aggressive behavior by using a path model. The participants in this study were 62 institutionalized children and 98 children reared at home, residing in an undisclosed city. The institutionalized children had a lower level of emotional intelligence and sense of humor than children at home. Also, the institutionalized children had a higher level of aggressive behavior than at-home children. Effects of emotional intelligence and sense of humor on the aggressive behavior were significantly different between institutionalized and at-home children.

This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated the changes in formalin-induced pain behavior according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The formalin-induced pain behavior was suppressed by pretreatment with BV into Chok-samni (ST36) in a dose dependent manner. During the early phase, 0.08mg/kg of BV showed a statistically significant suppression in the formalin-induced pain behavior. Moreover, 0.008mg/kg, 0.016mg/kg, and 0.08mg/kg of BV, except 0.0016mh/kg of BV, had significant suppresive effects on the formalin-induced pain behavior during the late phase. Therefore, these data indicated that the suppressive effect of BV acupuncture on the formalin-induced pain behavior was stronger in the late phase rather than the early phase 2. In order to investigate the analgesic effect of BV acupuncture into different treatment points, the experimental animals were divided into three groups: Chok-samni (ST36) group, gluteal group and back group. In the Chok-samni (ST36) group, the formalin-induced pain behavior during all the phases was significantly reduced as compared with that of the back group. However, as compared with that of the gluteal group, the formalin-induced pain behavior in the Chok-samni (ST36) group was decreased only in the late phase, not in the early phase. The formalin-induced pain behavior in the gluteal group was significantly reduced as compared with that of the back group in the late phase, not in the early phase. We suggested that the analgesic effect of BV acupuncture into Chok-samni (ST36) was most effective among Chok-samni (ST36), gluteal, and the back groups in formalin-induced pain behavior.

Background: This is a descriptive study to determine whether coursework that is focused on early diagnosis in cancer makes a difference in self-reported health promoting lifestyle behavior of students who study health management. Materials and Methods: The population of the study consisted of a sample of 104 students enrolled in the Department of Health Management at the Faculty of Health in Kirikkale University in Turkey. Forty-eight students enrolled in a course called "Early Diagnosis of Cancer" and fifty-six did not take this course. Demographic information was collected and the "Health Promotion Life-Style Profile (HPLP)" was used to collect health promotion data. Frequency and descriptive statistics including one-way ANOVA, Mann-Whitney U test, Kruskal Wallis tests were used to evaluate data. Results: The HPLP mean score of the students was found to be $127.5{\pm}17.45$. The highest mean score was observed for self-fulfillment and health responsibility, while the lowest was for diet and exercise sub-scales. It was found that certain variables were effective in developing health promoting lifestyle behaviors such as choosing this job voluntarily, working status of father and participation in social activity (p<0.05). In conclusion, it was found that the students had moderate levels of health promoting lifestyle behavior and they should be supported in terms of diet and exercise.

Melatonin, which is produced from tryptophan, exerts various biological functions, including the regulation of circadian rhythm, sedative agents, and antioxidant ability. Therefore, we conducted two experiments with early-weaned rats and pigs to investigate the antioxidant and sedative effects of melatonin. In the rat experiment, a total of 42 rats (21 days old) were used, and the antioxidant capacity was determined. Next, we used 120 early-weaned piglets (21 days old) to conduct a 5-week experiment to evaluate the reductive effect of melatonin on energy-wasting movement, including roaming and fight states. Dietary melatonin supplementation significantly improved growth in both rats and pigs compared to the control groups. Additionally, rats fed a melatonin-supplemented diet showed advanced antioxidant capacity with a decrease in hepatic malondialdehyde concentration compared to rats fed a basal diet. Moreover, dietary melatonin ingestion increased resting and feeding behaviors and reduced roaming and fight behaviors during Days 8-21 compared to the control diet group. Collectively, early weaned animals given dietary melatonin supplementation showed improved growth through upregulation of hepatic antioxidant capacity and minimization of energy-wasting behavior, including roaming and fight states, after pigs' social hierarchy establishment.

A previously published multiscale model for early-age cement-based materials [Pichler, et al.2007. "A multiscale micromechanics model for the autogenous-shrinkage deformation of early-age cement-based materials." Engineering Fracture Mechanics, 74, 34-58] is extended towards upscaling of viscoelastic properties. The obtained model links macroscopic behavior, i.e., creep compliance of concrete samples, to the composition of concrete at finer scales and the (supposedly) intrinsic material properties of distinct phases at these scales. Whereas finer-scale composition (and its history) is accessible through recently developed hydration models for the main clinker phases in ordinary Portland cement (OPC), viscous properties of the creep active constituent at finer scales, i.e., calcium-silicate-hydrates (CSH) are identified from macroscopic creep tests using the proposed multiscale model. The proposed multiscale model is assessed by different concrete creep tests reported in the open literature. Moreover, the model prediction is compared to a commonly used macroscopic creep model, the so-called B3 model.

A finite element formulation to predict the flexural behavior of composite girder is presented in which the early-age properties of concrete are specified including maturing of elastic modulus, creep and shrinkage. The time dependent constitutive relation accounting for the early-age concrete properties is derived in an incremental format by expanding the total form of stress-strain relation by the first order Taylor series with respect to the reference time. The total potential energy of the flexural composite member is minimized to derive the time dependent finite element equilibrium equation. Numerical applications are made for the 3-span double composite steel box girders which is a composite bridge girder filled with concrete at the bottom of the steel box in the negative moment region. The numerical analysis with considering the variation of concrete elastic modulus are performed to investigate the effect of it on the early-age behavior of composite structures. The one dimensional finite element analysis results are compared with the analytical method based on the sectional analysis. Close agreement is observed among the two methods.

With the introduction of durability examination into design code of concrete structure, a prediction of early-age behavior of concrete and its cracking resistance becomes very important. But, the early-age behaviors such as hydration, micro-structure development, moisture transport and mechanical properties development is quite complicated and coupled each other, and thus those can not be solved independently. One way to analyze those is to model their behaviors analytically and solve those computationally within a unified framework. In this paper, we propose a finite element technique to predict the early-age behaviors of concrete within the unified framework. The technique is applied to evaluatio of cracking in a massive concrete structure and then the analysis results are discussed.

In order to adapt to the economic change with the rapid world change, the wise consumers should have positive cognizance of their roles and are requested to fulfil their duties as a consummer. Such capability of the consumer could be acquired from home, mass media and school, and specially the role of mother at home would have a great influence on their early children's consummer activities. The purpose of this study was to investigate the interrelationship of the consumer behavior between mother and their children. As a result of this study, the mother with higher educational background could manage effectively the allowance of the children. The mother with older age had a great influence on the consumer's role of the children and high record of the execution. Employed mother had higher level of execution for the consumer's rights than their count part. Accordingly, the consumer behavior of the mother will have an influence on the children's consumer behavior. Such a result showed the meaningful statistic relations(r=3.6, p<.001) for the economy activity of the children the home management and economy life of the mother, and the purchasing activity of the children including the execution of the consumer's right. In their regard, there was the significant statistic relations(r=19, p<.05) between the children's pocket money and the housekeeping management of the mother. In the meantime, it showed that another changing factor concerned with the consumer behavior of the mother have little influence the children's allowance.
