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.

The purpose of this study is to examine the impact of marital conflict, parenting stress on married migrant women's parenting attitudes. Participants in this study were 109 married migrant moms of young children. The major results of this study were as follows: First, married migrant women's parenting stress and marital conflicts negatively related to warmth-encouragement, limit setting, but were positively related to rejection-noninteraction in parenting behavior. Second, married migrant women's warmth-encouragement in parenting behavior was affected by personal conflicts and couple relationship conflicts. Third, competence stress, attachment stress, spouse stress, isolation stress, and health stress also affected warmth-encourage parenting behavior. On the other hand, attachment stress, spouse stress and isolation stress had significant effects on limit setting in parenting behaviors. For rejection-noninteraction in parenting behaviors, depression and spouse stress affected significantly.

본 연구에서는 시멘트풀 및 모르타르의 초기재령 변형률 거동을 측정할 수 있는 경제적인 매입형 링센서를 고안하였고, 이를 활용하여 시멘트 풀 및 모르타르의 응결시간을 편리하게 측정할 수 있는 방법을 제안하고자 하였다. W/C가 0.30, 0.35, 0.40, 0.45인 배합들에 대하여 실험 연구를 수행하였다. 기존의 비카침과 관입저항침에 의해 측정된 응결시간과 제안된 방법에 의한 응결시간을 비교하였다. 실험결과에 따르면 개발된 링센서는 초기의 팽창거동이 수축거동으로 변화하는 수축의 시작시점을 정확하게 측정할 수 있었다. 또한, 수축 시작 시점을 응결에 대한 합리적인 기준으로 간주할 수 있었으며, 이는 기존 방법의 초결시간과 유사한 것으로 평가되었다.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by this study included field measurement survey, and non-participatory observation from 8 child care centers in Seoul. The field measurement survey were conducted from February 20 to March 20, 2005, whereas non-participatory behavior observation were conducted from June 15 to July 10, 2005. The major results showed the following. 1) Most of child care centers were too small, did not use the adequate surfacing to play various activities, and were made of play equipment setting. 2) Child's play behavior focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction of play setting produced functional play behaviors on children. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.

To investigate the influence of blade profiles on cavitation behavior in impeller of centrifugal pump, a centrifugal pump with five different blade profiles impellers are studied numerically. The impellers with five different blade profiles (single arc, double arcs, triple arcs, logarithmic spiral and linear-variable angle spiral) were designed by the in-house hydraulic design code using geometric parameters of IS 150-125-125 centrifugal pump. The experiments of the centrifugal pump have been conducted to verify numerical simulation model. The numerical results show that the blade profile lines has a weak effect on cavitation inception near blade inlet edge position, however it has the key effect on the development of sheet cavitation in impeller, and also influences the distribution of sheet cavitation in impeller channels. A slight changing of blade setting angle will induce significant difference of cavitation in impeller. The sharp changing of impeller blade setting angle causes obvious cavitation region separation near the impeller inlet close to blade suction surface and much more flow loss. The centrifugal pump with blade profile of setting angle gently changing (logarithmic spiral) has the super cavitation performance, which means smaller critical cavitation number and lower vapor cavity volume fraction at the same conditions.

The expansion of information sharing activities using online can increase the threat of information exposure by increasing the diversity of approaches to information within an organization. The purpose of this study is to present conditions for improving the information security compliance intention of insiders to improve the level of information security within the organization. In detail, the study applies the theory of planned behavior that clearly explains the cause of an individual's behavior and proposes a way to increase the compliance intention by integrating the social control theory and goal-setting theory. The study presented research models and hypotheses based on previous studies, collected samples by applying a questionnaire technique, and tested hypotheses through structural equation modeling. As a result, information security attitude, subjective norms, and self-efficacy had a positive influence on the intention to comply. Also, attachment, commitment, and involvement, which are the factors of social control theory, formed a positive attitude toward information security. Goal difficulty and goal specificity, which are the factors of goal setting theory, formed a positive self-efficacy. The study presents academic and practical implications in terms of suggesting a method of improving the information security compliance intention of employees.

Purpose - This study has its purpose to identify the correlation between factors and moderating variables that can reduce job burnout by setting a positive relationship with a leader and ethicality of the leader as factors reducing job burnout and helping behavior as a moderating variable. Research design, data, and methodology - The research design would make theoretical perceived ethical leadership and LMX toward helping assistance, and job burnout using by structural equation method. Results - As a result, both positive behaviors and recognition on ethical leadership of a leader have been confirmed to influence on mitigation of job burnout. Especially, among the two factors, ethicality has shown to be more efficient to alleviate exhaust compared with positive behavior of a leader. Conclusions - Theoretical perceived ethical leadership and LMX toward a leader, helping assistance, and job burnout are statistically significant, however, the helping behavior of members is the factor increasing a job burnout. These results can be interpreted as the difficulties of relation setting with the members for the leader, and although loyalty and responsibility toward right leader may induce helping behavior, and positive behavior for organization can impact on the job burnout. It can be concluded that the ethicality of a leader is an essential factor for the development of organization.
