National and social issues are becoming increasingly common, but traditional policy-making methods are no longer effective. Therefore, evidence-based policy making is emerging as an alternative paradigm. Digital twin technology is one of the digital support tools for the new data-driven policy-making process. This study presents ongoing government experiments in the world where digital twin technology is applied to policy making and describes our experience in developing digital twin platforms in Sejong-the de facto administrative capital of South Korea.

This study investigates the credibility judgements of information by tweens using digital media and information. Particularly, the study focused on tweens' perception of internet research and information use and on their credibility judgement of source and message, internet service providers, and on consulting with others for their credibility judgement. The survey methodology was used to collect data from grade 5 and 6 students in two elementary schools whose parents are likely in middle and upper class. 336 valid questionnaires were collected among 400. Descriptive statistics, factor analysis, and t-test were used to analyze the data collected using SPSS 25. Findings suggested that tweens understood the importance of using smart media and computers, that they used Youtube, Naver, Kakao talk, Naver JisikIN much in sequence, and that they believed the Internet research was easy and fun. Using exploratory factor analysis, the survey questions for credibility judgement were classified into three factors: Internet service providers, sources and information, and consulting with others. Tweens used sources and information credibility, consulting with others credibility, Internet service providers credibility in sequence. However, it was interesting to find that there were greater deviation in answers on knowing how to find out the cognitive authority of the authors and on the importance of using current information. This study suggests the critical need for tweens' credibility judgement research for promoting critical thinking skills as well as for proactive educational practices in schools and libraries on information literacy.

요즈음 우리 사회에 유행하는 신세대론은 사회적 실체에 기반을 둔 분석적인 개념이라기보다는 상당 부분 매스컴이 만들어내는 가상현실에 기반하여 만들어진 것이라 할 수 있다. 어느 사회, 어느 시대에서나 존재하는 세대차이를 신세대라는 범주로 묶으려는 것은 바로 시장을 세대별로 세분화하여 상품의 영역을 확대함으로써 이윤을 극대화하려는 자본주의 시장논리이다. 이러한 맥락에서 신세대라는 개념이 등장하게 되었고 뒤이어 미시족, 체크족, 트윈 X세대 등 여러 용어로 범주화되는 유사 세대개념들이 등장하며 또 이 개념들이 매스컴의 스포트라이트를 받고 있는 것이다. 따라서 우리는 신세대론에 매몰되어 그들을 도덕적으로 판단하기보다는 변화되는 사회환경의 분석과 함께 그들의 문화를 이해하고 포용하여 눈높이를 맞추려는 노력을 기울일 필요가 있다.

The purpose of this study was to examine how the garment sizes by junior brand manufactures reflect Tween Generation's (ages from 5th grade to 9th grade) actual body sizes. They have diverse clothing preferences in styles and fitting levels as well as diverse body sizes and shapes. The subjects of this study were 520 students (the 5th and 6th grades in elementary schools, the 1st, 2nd and 3rd grades in middle schools) who lived in Jeonju. A questionnaire was used in this study. The data were analyzed by frequency, means, t-test and $\chi^2$. The results were as follows. In the selection of garment size, both the girl and boy students most preferred selecting garments after trying them on by themselves. Boy students tended to select garment size according to their mothers' advice. On the other hand, elementary school students showed a tendency to select garment size with their mothers. In fitting sizes, middle school girls wanted the size to fit tightly rather than loosely on their bodies much more than elementary school girls. Junior brand manufacturers produced sizes that well reflected actual body sizes of elementary and middle school girls. Specifically, the pants best covered their body sizes.

This study is aimed at developing low waist slacks pattern with high satisfaction measurements and beauty for the tween generation girls. For this study, the research method was as follows. By extracting and analyzing industrial and educational slacks pattern, beautiful and motion-suitable slacks pattern will be created. This study presents the ideal slacks pattern that has great fit to tween generation girls by comparing and analyzing the previous 2 slacks pattern studies and the real clothing test. The constructed pattern in the 1st step was modified and adjusted from the best industrial patterns' the location of waist line, waist line gradient, rear waist bottom crotch, hip bottom crotch, dart length, the ease of hip girth, the fitness of rear bottom crotch line which were not well-estimated. The 2nd step was appearance and movement test based on the 1st study. In The 3rd step, the 2nd step was chosen as the final slacks study pattern for its superior appearance & movement satisfaction comparing with other patterns.

The purpose of this study was to examine the fashion brand attitude of tweenagers, with a focus on brand awareness, image, identification and loyalty. The study analysed 541 fifth and sixth-grade students in Seoul elementary schools. Major statistical methods used for this study were Cronbach's alpha analysis, confirmatory factor analysis, and path analysis with SPSS 19.0 and AMOS 19.0. Brands selected for this study were "NIKE" and "BEANPOLE KIDS". The result of this study was as follows: First, the study showed that both "NIKE" and "BEANPOLE KIDS" had 4 significant routes from the research model. Brand awareness had influence on brand image; brand image had influence on brand identification and brand loyalty; and brand identification had influence on brand loyalty. Second, using the bootstrapping to verify the significance of the total effect and indirect effect, brand awareness had a significant indirect effect on brand identification and brand loyalty; brand awareness did not have any direct effect on brand identification and brand loyalty for both "NIKE" and "BEANPOLE KIDS". Also, the total effect of brand awareness on brand identification and brand loyalty was significant. The result of this study showed the development potential to the fashion companies targeting tweenagers.

The aim of this study is to examine the tween generation's (11 to 15 years-old) clothing purchase tendency. Based on the questionnaire, the data were collected from 187 elementary school students(11 to 12 years-old) and from 293 middle school students(13 to 15 years-old) in Jeonbuk. The data were analyzed with the factor analysis, Chi-square analysis, t-test, F-test. The research shows: the tween generation rarely if ever buy their clothing by themselves, and they usually accompany their mothers when they purchase their clothes. In the 'size fitness', girl tweenage group prefers a perfect fit to an easy one. But boy tweenage group shows a different tendency from them. In the 'fashion adaption', the tweenage group of 13 to 15 year-olds responds in a sensitive way. The 'style', 'design' and 'color' of clothing are the most decisive factors in their purchasing trend. Especially, the boy tweenage group prioritize the factors in the order of 'brand value', 'price' and 'trend'.

The purpose of this study was to provide basic information on the propriety of the ready to wear garment sizes of Tween Generation(ages from 5th grade to 8th grade) who has different clothing preferences in color, styles, and design and also different body sizes and shapes from younger and older students. The objectives of the study were to ascertain (a) the body figure changes occurring during Tween Generation; (b) the coverage of manufactures'garment sizes. The body measurements of elementary school students(5th & 6th grades) and junior high school students(7th & 8th grades) provide the basic statistics for this study. The mean differences of each size within each figure type are compared by using t-teats. The differences in various manufacturers'apparel sizing and figure size are investigated. Also the body measurements and the apparel sizes of the manufacturers are compared in order to evaluate the suitability of the garment size. Results indicate that the body type factors are different in each age group. And manufactures'sizes come out to be much smaller than the actual body measurements. Young casual wear can cover junior high school students satisfactorily but for elementary school students, because of low drop-value, the overall satisfaction with filling is low.

This study provides the basic data for clothing construction of teen girls by researching and analyzing the characteristics of physical changes of tween generation school girls between 8 to 14 age. Fifty eight items of direct measurements and 61 calculated-items based on the 6th Korean National Physical Standard Reports were used. Results were obtained by using ANOVA, SNK test, coefficient of variation and growth rate of age groups. Significant differences were found among all the age groups, and were in the increasing order of height > length > width > depth > circumference. The growth rate was found in the increasing order of bust depth > hip width > N.P. to B.P. > hip circumference > bust circumference and thigh circumference. There were dramatic increases in height, circumference and width during the age of 8~9 and 10~11, in length during age of 10~11, and in depth during age of 8~11. The growth of the vertical measurement items is slowing at the age of 13. The individual differences were great in the vertical measurements at the age of 8 and 9 and in the horizontal measurements, at the age of 10. The increasing growth of bust and hip than waist gave it a curved shape.
