The purpose of this study was to examine the relationships among mother's psychological characteristics(self-esteem, self-efficacy, and depression), parenting related factors(maternal parenting stress and mother's knowledge on infant development), maternal parenting style, and two-year-old infants' development. The participants consisted of 1735 mothers and their two-year old infants selected from a sample of the 3rd Panel Study of Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE), conducted in 2010. Data were analyzed by means of a Structural Equation Model(SEM) to identify the structure and relationships among the various factors. The significance of direct and indirect effects to test the mediating effect of maternal parenting style were identified via bootstrapping. The results indicated that maternal parenting style most definitely mediated the relationship among the mother's psychological characteristics(self-esteem and self-efficacy), parenting related factors(maternal parenting stress and mother's knowledge on Infant development) and the development of their two-year-old infants.

Purpose: This study was to investigate and identify the factors that affect the hotel workers' health status. Method: The subjects of this study were 261 randomly selected servers from a hotel located in Seoul. For the statistical analysis of collected data, descriptive statistics, $X^2$-test, ANOVA and Tukey's multiple comparison(Tukey's post hoc), multiple regression were done with the SAS(Version, 9.01) program. Results: The health status scores were significantly different depending on the type of their occupation. The health status and the subordinate concepts such as social function, role limitation-physical and bodily pain scores were significantly different. The factors that affect health status of foods & beverages workers were emotional labor, physical environment, social support and self efficacy. In culinary, they were affected by job satisfaction and the experience of seeing a doctor. The workers in room-service were affected by experience of quitting. Conclusion: To improve health status of the hotel workers, the results of the study suggest that physical environment, emotional labor, self-efficacy and job satisfaction be enhanced. As the frequency of seeing the doctor affected their health status, further study is recommended and systematic health promotion program needs to be developed.

To make good use of chitosan forming complex with heavy metals in wood preservative treatment, woods impregnated with chitosan and copper sulfate were prepared. Amounts of leached copper, decay resistance, anti-mold efficacy, iron corrosion rates, moisture regain rates and degradation pattern in chitosan pre-treated and untreated wood were compared. After leaching test, amounts of leached copper from chitosan pre-treated wood had a much smaller than chitosan untreated wood, and good decay resistance was retained even after leaching test. From these results, it was proved that chitosan-copper complex formed in wood played and important role for decay durability. In chitosan pre-treated wood, damage values by test molds became remarkably smaller, but the growth of test molds was not perfectly inhibited. Distinct differences in iron corrosion rates between chitosan pre-treated and untreated woods was not recognized but chitosan pre-treated wood showed the lower moisture regain rates than chitosan untreated wood because of water insoluble chitosan membrane formed in wood. After leaching test, the tracheid walls in the wood treated with 2.0% copper sulfate only were eroded by the fungal attacks, but those in the wood pre-treated with chitosan remained almost intact.

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.

Technology adoption has been an important issue for researchers and practitioners. In this paper, we identified the relationships between intention of technology adoption and technological affinity and other psychometric characteristics. We believe that technology affinity may be one of the general psychometric traits of individuals, and thus people have a different affinity levels which may influence the technology adoption intention. As a result it was found that need for cognition and self efficacy had positive influence on technology affinity, and the affinity also positively affected adoption intention. In addition, it was also found that technology affinity displayed a mediating role for the consumers adoption intention with need for cognition and self efficacy.

In recent years, social media that has emerged with the development of network technology has changed the channels of information dissemination. The social Q&A community is a platform for knowledge-sharing activities in a question-and-answer manner based on Web 2.0. In knowledge-sharing activities, valuable new knowledge continues to be produced and will surely bring great benefits to individuals or businesses. In the social Q&A community, the user's subjective factors play a crucial role in influencing the user's continued use and participation in knowledge-sharing activities. In order for users to actively participate in knowledge-sharing activities in the community, it needs to grasp their subjective ideas. This study explores the issue of sharing knowledge by users of the social Q&A community "Zhihu", or how to drive community revitalization efforts from these. The three factors self-efficacy, self-development motivation, and social comparison tendencies were derived, and identify their relationship with knowledge-sharing activities and community-boosting efforts through empirical analysis. In addition, the influence of knowledge acquisition on knowledge provision was investigated through sense of reciprocity. Implications of the study findings and the future research directions were also discussed.

The demand for orthodontic clear aligner therapy (CAT) has increased significantly over the last decade, offering advantages over the fixed appliances (FA) including enhanced aesthetics, better hygiene and comfort, along with minimal restrictions on the patient's diet. Moreover, a marked improvement in the efficacy of tooth movement using aligners has been documented. On the contrary, there have been known limitations of CAT including the compliances issues and the apparent lack of efficacy for certain types of tooth movement such as closure of extraction space compared to FA. Thus, evidence-based evaluation of the accuracy of prediction of tooth movement with clear aligners and their ability to effectively perform major tooth and root movements compared to FA are crucial. Although several systematic reviews have investigated various aspects of the effectiveness of CAT, we are yet to obtain a rather conclusive answer to this question. The current review attempted to summarize the evidence-based findings of most systematic reviews about CAT available to date. Major issues regarding the predictability of tooth movement, the role of attachments and auxiliaries in improving the effectiveness of CAT, and the treatment outcomes in comparison to FA were investigated. Clinical recommendation have been also elaborated based on the interpretation of the findings of all systematic reviews included in this study.
