Objective: The purpose of this study was to explore the structural relationships among duration of media use, behavior problems, and school adjustment, while accounting for gender differences. Methods: The study used 4th-wave panel data from the Korean Children and Youth Panel Study, and 2,119 first graders in elementary school were analyzed. The data were analyzed using Structural Equation Modeling. Results: The results can be summarized as follows. First, the duration of media use had a direct effect on school adjustment. Secondly, the duration of media use had an indirect effect on school adjustment through internalizing and externalizing problems. According to multigroup analysis, gender differences were found in the structural relations among variables. Conclusion: This study emphasizes the needs for media usage education to improve children's school adjustment. Furthermore, it suggests that different intervention strategies for internalizing/externalizing behavior problems are needed depending on gender.

Action learning is a teaching method that is taught through the process of finding real problems and finding solutions. The purpose of this study was to examine the effectiveness of action learning for the college course 'media education for children' which was offered by the Department of Child Psychology and Education at S university in Seoul. According to the process of action learning suggested by Marquardt(2000), college students developed the problem of children's news literacy education and set the purpose, goal and contents of news literacy and developed teaching and learning method for the 6th grade elementary students and applied it to the education field. The college students' evaluation about the action learning lesson were collected by questionnaire and verbal. They found that active and voluntary problem-solving and field application through action learning helped to achieve the goals of the children's media education class. Finally, the importance of close cooperation with the educational field and of appropriate feedback were discussed as a necessary condition of action learning teaching method.

Tableware is among the important necessities of daily life, and children's tableware is especially valued by the society. Under such social background, a study centered at users of children's tableware was conducted from four aspects, including health & safety, sensory experience, behavior guide, and emotional cognition. Children's tableware products were evaluated using the Q method to understand users' cognition of children's tableware products. The interviewees' views about children's tableware design in China can be divided into four types,and put forward different psychological needs for these four types, In the interviews, some interviewees suggested that the ergonomic and regional cultural differences shall all be considered during children's tableware design. Therefore, this study evaluates the design preferences of Chinese children tableware and validates the results of the paper based on the results.

The results of this research demonstrated that first, educare teachers' adult attachment had indirect effects on the young children's adjustments by the media of self-efficacy. Second, the educare teachers'adult attachment was found to have indirect effects on the young children's adjustments by the media of discipline styles. Third, the educare teachers' adult attachment was found to have effects on the young children's adjustments through self-efficacy and discipline styles.

Streptococus pneumoniae is an important cause of invasive infections as well as non-invasive infections such as acute otitis media and sinusitis both in children and adults. Resistance of S. pneumoniae to multiple antimicrobials is increasing and poses therapeutic challenges, and prevention became more important. 23-valent polysaccharide vaccine has been used for the last several decades, but is not effective in children <2 years of age, the highest risk group of invasive diseases. Recently, a 7-valent pneumococcal protein conjugate vaccine(PCV) which is effective in infants and young children has been developed. The efficacy of PCVs against invasive pneumococcal disease and pneumonia is well established and is documented in several well-conducted studies. However, the effect of PCVs on otitis media is less obvious and more complex. PCVs clearly reduce diseases caused by vaccine-type(VT) pneumococci, but replacement of VT serotypes by non-VT serotypes in nasopharyngeal carriage of S. pneumoniae is responsible for the increase in acute otitis media caused by non-VT serotypes. Three years after introduction of PCV in the US, some increase of invasive infections with serotype 19A possibly due to serotype switching within certain vaccine type strains has been noted. Since most antibiotic-resistance in S. pneumoniae is confined to VT serotypes, vaccine use also reduces antibiotic resistance. With development of PCV, there was a great advance in the prevention of pneumococcal diseases, but replacement with potential virulent organisms and development of antibiotic resistance in non-VT pneumococci is a possibility that needs careful monitoring.

Ecological predictors of imaginative playfulness were researched to test relationships among preschoolers' individual characteristics, socioeconomic status, their visual media use, and their imaginative playfulness. Data were collected from 202 primary caregivers and head teachers in childcare centers in Michigan, U. S. A. Use of visual media was coded by the program categorization of Anderson et al. (2001) and the Television and Movie Violence Rating Scale (Huesmann et al. 2003). Imaginative playfulness was rated by the adapted Playfulness Scale (Barnett 1990). Results of hierarchical regression showed that child characteristics of age and gender predictors contributed to their imaginative playfulness. On the other hand, children's visual media use and socioeconomic status of their families did not predict their imaginative playfulness.

Acute otitis media (AOM) and pneumonia are among the most common infectious diseases of children. Both are mucosal infections and share many common features such as etiological agents, pathogenesis and immunity. Influenza plays an important role in the pathogenesis of AOM and pneumonia. A vaccine against influenza may have substantial impact on these diseases during the influenza season. In clinical trials, influenza vaccine has reduced the incidence of AOM and pneumonia complicating influenza in children. However, the efficacy of vaccines has been controversial in children less than 2 years of age. Similarly, vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib), both common causes of AOM and pneumonia, have the potential to reduce the impact of disease. Clinical trials showed that the currently licensed 7-valent pneumococcal conjugate vaccine (PCV), administered during infancy, had an efficacy of 6-7% for the prevention of AOM, however, visits to the clinic for AOM were reduced by up to 20-30% after routine use in the U.S. Both Hib and PCVs have a proven effectiveness of >20% for prevention of radiologically confirmed pneumonia in children. The recently introduced pnuemococcal vaccine conjugated with protein D is expected to reduce AOM and pneumonia caused by non-typable H. influenzae, in addition to its effects on pneumococcal diseases. Considering their high incidence in children, recent achievements in the prevention of AOM and pneumonia with vaccines may have a significant economic and social impact.

With wide spread of smart devices, the use of children's smart devices were increased. We have performed an exploratory study about children's use of smart devices in the viewpoint of lives of children. The children was encouraged on the school centered learning by their parents. In this study, we wanted to explore the state of life of children's using of smart devices in the view of the children's life at the age of information society. The results show that there was a difference in children's using of smart devices between big and small city. This research shows that the students have the lack of the experiences of learning of desired usages and learning with devices. In the play with the non-electronic media, outside play was more than indoor play. Half of the answers at the amount of time to play the game and to watch the TV were "within an 1 hour". We know that the proportion of children's indoor play portion is more than outdoor play of it.
