I measure aggregate productivity growth in manufacturing between 1995 and 2013 as defined by Petrin and Levinsohn (2012). I decompose aggregate productivity growth into technical efficiency improvements, resource reallocations, and net entry effects. I find that aggregate productivity growth slows down after 2004 and that the rapid drop in technical efficiency growth contributed most to the decline. In this paper, I focus on the role of young plants with regard to productivity growth of Korean manufacturing. I show that young plants account for nearly half of APG (48%), while their value-added share is 14 percent on average between 1995 and 2013. I find that productivity growth at young plants has been declining for the last ten years. The lower growth of continuing young plants contributes to this trend. These results stress the important role of young plants in aggregate productivity growth and imply that understanding the dynamics of young plants is necessary to form effective start-up policies.

The author has observed the gross reactions of surrounding maxillary sutures to the widening of midpalatal suture in comparison of young dog with adult dog. Experimental animals used was two young dog and two adult dog with normal palate. After midpalatal suture was seperated with rapid palatal expansion device, experimental animals were sacrificed to observe the surrounding maxillary sutures. The following results were obtained. 1. In adult dog, nasoincisive suture was not expanded, while in young dog it was expanded. 2. In adult dog, pterygopalatine suture was hardly expanded, while in young dog it was expanded definitely. 3. In adult dog, frontomaxillary suture was not expanded, while in young dog it was expanded unilaterally. 4. In adult dog, palatoethmoidal suture was not expanded, while in young dog it was expanded unilateraily.

Purpose: We aimed to compare the prevalence rates and associated symptoms of constipation and fecal incontinence in children and young adults and evaluate how these patient groups cope with these disorders. Methods: A cross-sectional study was performed in which 212 children (8-17 years) and 149 young adults (18-29 years) from the general Dutch population completed a questionnaire about defecation disorders. Results: Constipation occurred in 15.6% of children and 22.8% of young adults (p=0.55), while the prevalence of fecal incontinence was comparable between groups (7%, p=0.91). The symptoms associated with constipation occurred as often in children as in young adults, while most fecal incontinence symptoms occurred more often in young adults. Approximately 43% of children had constipation for more than 5 years, while 26% of young adults experienced constipation since childhood. Only 27% of constipated children and 21% of constipated young adults received treatment (mostly laxatives). For fecal incontinence, 13% of children and 36% of young adults received treatment (mostly antidiarrheal medications or incontinence pads). Conclusion: In contrast to the general belief, the prevalence of defecation disorders and associated symptoms seem to be comparable in children and young adults. Only a few people with defecation disorders receive adequate treatment.

The purpose of this study was to investigate the role of variables on young children's external aggression and relational aggression. Specifically, young children's temperaments and gender differences, parental marital conflicts, fathers' anti-social behaviors, mothers' child-rearing behaviors and psychological characteristics were studied. The findings of the study were as follows: Firstly, it was found that male children exhibited a higher level of external aggression than female children, while there was no significant difference between male and female children in terms of relational aggression. Secondly, analysis of variables such as children's temperaments and domestic environments revealed that fathers' anti-social behaviors, the adaptability of young children's temperaments and mothers' depression tendency have significant explanatory adequacies for young children's relational aggression. Furthermore, gender difference adaptability, activity and emotionality of young children's temperaments, in addition to parental marital conflicts, also have significant explanatory adequacies for young children's external aggression.

Data were analyzed by the method of frequency, percentage, Cronbach' ${\alpha}$, factor analysis, T-test. F-test, and Duncan post-hoc test using SPSSWIN program. The test of model was done with analysis of correlational matrix in LISREL VII package using a maximum likehood estimation. The results of this research were as follows: First, there were statistically significant differences in mother's characteristics consisting of neurosis symptom and extroversions, disciplinary methods consisting of coercive-punishment and indifferent-irresponsibility, young children's emotional regulation, and young children's aggression consisting of relation and overtness according to some socio-demographic variables. Girls had the higher emotional regulation than boys. Second, the direct effects of disciplinary methods and emotional regulation on boys' aggression were different in between relational and overt aggression. Third, the variables predicting boys' emotional regulation directly were the same in both relational and overt aggression. Forth, the direct effect of mother's characteristics on disciplinary methods was different in between coercive-punishment and indifferent-irresponsibility. Fifth, the indirect effects of mother's characteristics, mediated by disciplinary methods and young children's emotional regulation, on young children's aggression were partly supported in this study.

Young adults are not met adequately by the traditional public library service patterns, being compared for children and adults even though they belong to the main user groups in number. Adolescence is a unique developmental stage distinct from childhood and adulthood and it is fair to say that today's young adults face complex present and confusing future. Projects are made to address the full spectrum of the young adults needs and the important role of public libraries as partners to solve the social youth problems in the USA. The library professional organizations issued young adult service guidelines, recommendations, and manuals to assist public libraries to offer good service programs to young adults. This paper provides the basics of young adult services in the public libraries to help Korean public libraries acknowledge the importance of young adult services and improve the framework of young adult services.

The media culture influences upon young people while introducing new cultures by every hour. Considering the mainstream culture, in which media has the greatest effect on young people, this article examines the symbolic significances of youth fashion through media culture. The results of this study can be summarized as the following: First, young people's popular culture ("pop culture") is becoming the medium that leads to the creation of similar cultures of the young people globally through various routes. Culture is being created by integration of diverse media, and not by what is seen through a single medium. Typical young people's culture, which is formed due to the influence of media culture, includes community culture, pun culture, virtual culture and fandom culture. Second, in order to examine youth fashion that is seen in those media, the survey has been conducted on media stars, tecktonik dance groups, fashion models, avatars and online communities, which are fashion icons influencing young people. Third, youth fashion, which has been formed centering on media culture, has the flexible property that varies the symbolic significance according to which culture becomes the main axis. The symbolic significance in fashion, which is seen on media culture young people are contacting, has been examined in the aspects of value orientation, diversity orientation, speed orientation and digital orientation.
