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.

An effective design of a public space that properly functions as a resting place in city can be found through the community facility studies. This study, based on the ecological psychology, discusses the mutual relationships between human behaviors and physical and social environment. It is demonstrated that design elements, such as chairs, tables, stairs, a flower bed, a stair-shaped exterior wall, a pond and others play important roles in providing environment for different human behaviors in public space. These environmental design elements also increase a variety of behavior for users.

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.

The present study proposes an economical embedded ring-sensor that can measure a strain behavior of cement paste and mortar in early age. Using the proposed ring-sensor, the experimental method is proposed that can measure the setting time of the cement paste and mortar conveniently. The experimental study has been conducted using the mixtures of which W/C are 0.30, 0.35, 0.40, and 0.45. From the test result, the setting times measured by convectional test methods such as vicat method and penetration resistance method are compared with the setting time proposed by this study. The result reveals that the proposed ring-sensor can effectively measure the early age behavior so that can evaluate the time when the contraction starts. In addition, the contraction starting time can be regarded as a rational setting time, which is similar to the initial setting of convectional test methods.

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.

This study analyzed the direct and indirect effects of job competency education on job goal setting, job preparation behavior and first job satisfaction from the perspective that successful employment requires improving the job ability needed for college students. Data on 5,044 students were analyzed based on the 2013GOMS of Graduates Occupational Mobility Survey(GOMS). The study findings are summarized as follows. First, job competency education not only acted positively on job goal setting but also contributed to promoting job preparation behavior. Second, job preparation behavior contributed to improving satisfaction with the first job. Third, indirect effects of job competency education and job goal setting in first job satisfaction. In conclusion, job competencies enhances the possibility that college students may obtain their wanted job by setting a clear goal for their job and having a positive effect on the required behavior. Accordingly, college student should try to reinforce their special capability to accomplish the given job as career professionals in consideration of their aptitude rather than devoting themselves to reinforcing their basic capability such as linguistic ability. For this purpose, both universities and the government should develop educational programs for college students to grasp their aptitude and cultivate their special ability to become career professionals and provide a foundation for them to become talented professionals armed with special capability by proving support for job ability improvement.
