This article considers short-form fashion videos as distinguished from fashion films, defines the concept, details the expressive characteristics of short-form fashion video, and reveals the method of producing it. For the methodology, a literature review was conducted to derive the concept and expression techniques. A case study was also performed to define the expressive characteristics. Five short-form fashion videos were also produced based on the results. The final results are as follows. First, short-form fashion video was defined as a fashion medium on the purpose of fashion communication within 60 seconds and classified by three digital image formats. Second, the result of analyzing the expression of the short-form fashion video shows the simplicity and reconstitution, characterization and remediation, borderless and expansion, and synesthesia trigger of the fashion image. Third, five short-form fashion videos were produced based on the theme of the digital garden. It shows that the short-form fashion video intensively expresses the content as a medium whose sensational expression is more prominent than the composition of the story by the short running time that reflects the taste of digital mainstream.

With the emergence of digitalization and environmental changes, such as those caused by COVID-19 and high-speed networks, online video platforms have changed how people communicate and created new marketing opportunities. The unique characteristics of mobile short-form videos are causing more people to consume and produce diverse content in the digital environment. The study focuses on two story types (product essential and relative information) to examine the effectiveness of short-form videos for fashion marketing. This study verified the influence of the common traits of short-form video content (informativeness, expertise, familiarity, and playfulness) on fun, e-WOM, and purchase intention and the mediation effect of fun using video samples categorized by story type. In this study, 300 Gen Z men and women responded to a survey after watching a 30-second short-form video sample. All the traits of short-form video content were found to have a positive effect on fun. Moreover, all the traits excluding playfulness had a positive effect on e-WOM and purchase intention as well. Fun had a positive effect on both e-WOM and purchase intention as well as a partial mediating effect. These findings are expected to provide insight and reference for planning short-form video marketing from the perspective of the fashion industry.

For maintaining adequate psychometric properties when reducing the number of items from an instrument, item level psychometrics is crucial. Strategies such as low item correlation or factor loadings, using classical test theory, have traditionally been advocated. The purpose of this study is to describe the development of a new short form assessing the impact of low back pain on physical activity. Rasch measurement model has been applied to the International Classification of Functioning, Disability and Health Activity Measure (ICF-AM). One hundred and one individuals with low back pain aged 19-89 years (mean age: $48.1{\pm}17.3$) who live in the community were participated in the study. Twenty-seven items of lifting/carrying construct of the ICF-AM were analyzed. Ten items were selected from the construct to create a short form. Item elimination criteria include: 1) high or low mean square (out of the range: .6-1.4 for the fit statistics), 2) similar item calibrations to adjacent items, 3) person separation value, and item-person map for potential gap in person ability continuum. All 10 items of the short form fit to the Rasch model except one item (i.e., carrying toddler on back). Despite its high infit and outfit statistics (1.90/2.17), the item had to be reinstated due to potential gaps at the upper extreme of person ability level. The short form had a slightly better spread of person ability continuum compared to the entire set of item. The created short form separated individuals with low back pain into nearly 4 groups, while the entire set of items separated the individuals into 6 groups. The findings prompted multidimensional models for better explanation of the lifting/carrying domain. The item level psychometrics based on the Rasch model can be useful in developing short forms with rationally retained items.

이 글은 1990년부터 진행된 미국의 인구센서스의 변화와 향후의 전망에 대해서 2000년의 경험과 2010년의 계획을 중심으로 논의한다. 먼저, 2000년 센서스의 준비과정에서 미국 과학원학술평의회 국가통계위원회가 작성한 2000년 센서스 개선안의 내용을 통계적 추정방법 도입, 응답률 개선방안, long form 개선방안, 소수민족 집계누락, 인구센서스 대체방안, 센서스 비실시 연도 소지역통계 확보방안, 센서스 프레임 정비 등으로 살펴보고, 1998년 대법원 판결 이후 2000년 센서스에서 통계적 추정방법을 이용한 미국판 One Number Census를 추진하지 못하게 된 경위를 검토한다. 다음은 2010년 인구센서스의 핵심적 특성의 하나인 long form과 short form의 분리, 곧 short form은 전통적 센서스, 곧 전수조사와 현장실사의 원칙을 준수하는 방식으로 그대로 두고, long form을 대체하여 순환센서스로 진행되는 American Community Survey에 대해서는 그 과정과 주요 특성을 검토한다. MAF/TIGER는 인구센서스의 집계과정에서 정확성을 향상 하고자 하는 또 하나의 특성으로, 이것은 2010년 센서스에서 모바일 컴퓨터를 도입하는 하이테크 센서스를 목표로 기획된 것이었다. 이 글은 미국 센서스에서 short form과 long form의 분리가 대법원 판결로 우연히 일어난 것이 아니라는 점을 강조하기는 하지만, 미국 센서스는 2008년 현재, 인구조사국의 모바일컴퓨터 개발실패로 60만 비정규직 조사원의 고용을 불가피하게 할 것으로 예상되며, 이로 말미암아 2010년 미국 센서스의 정확성에 대한 우려감이 증대하고 있음을 지적한다.

The popularity of short-form video platforms like TikTok has increased recently. Short-form videos are significantly shorter than traditional videos, and viewers regularly switch between different types of content to watch. Therefore, a successful prefetching strategy is essential for this novel type of video. This study provides a resource-effective prefetching technique for streaming short-form videos. The suggested solution dynamically adjusts the quantity of prefetched video data based on user viewing habits and network traffic conditions. The results of the experiments demonstrate that, in comparison to baseline approaches, our method may reduce data waste by 21% to 83%, start-up latency by 50% to 99%, and the total time of Re-buffering by 90% to 99%.

This study was conducted to design long and short forms of reliable and valid Likert-type scales to measure environmental attitudes of Korean junior high school students. 8 tests were applied to the construction of a 32-item long form and 8-item short form of the scale. Two scales were field tested on 469 respondents consisting of male and female students in urban and rural areas and students participating in environmental programs. The 32-item scale was revealed to be highly reliable, content and construct valid. Reliability and homogeneity of this scale were evidenced by 0.92 coefficient alpha and positive interitem correlation values ranging from 0.10 to 0.52. Factor analysis and known-group comparison showed the sufficient validity of long form scale. Reliability and validity of short form scale were also evidenced by good results of 8 test analyses. The long and short forms were strongly correlated, ${\gamma}$-value of 0.90. Consequently, both long form and short form scales were evidenced very reliable and valid in measuring environmental attitudes of junior high school students in Korea. They can be useful for a variety of survey conditions and constraints and testing environmental attitude.

Both erythropoietin (EPO) and the short-form thrombopoietin (TPO) were expressed at low levels whereas the long-form TPO was expressed at high levels in transgenic animals. To elucidate the role of carboxy-terminal half of the long-form TPO which is absent in the short-form, we generated recombinant TPO or EPO expression vectors which contain or lack the carboxy-terminal half of TPO and examined their expression in the HC11 and 293 cells. The long-form TPO was expressed higher than the short-form regardless of the cell types, transfection modes, and promoters. When 3'-half of the long-form TPO cDNA was placed downstream of the EPO cDNA to act as a 3'-untranslated region, expression of EPO was moderately increased at the RNA level, however, no remarkable increase was observed at the protein level. These results suggest that the low expression of EPO, as like as the short-form TPO, is due to absence of the 3'-half in the full-length TPO that confers stability both at the RNA and protein levels.

The purpose of this study was to design a reliable and valid Likert-type scale to measure nuclear energy attitudes of various groups. 8 tests were applied to the construction of a 26-item long form, a 12-item middle form, and a 6-item short form of the scale. Three scales were field tested on 760 respondents representing a diverse range of subjects. The 26-item scale appeared to be reliable, content valid and construct valid. Scale reliability and homogeneity were evidenced by 0.95 coefficient alpha and positive interitem correlations ranging from 0.18 to 0.74. The results of factor analysis and known-groups comparison revealed that this scale had high validity. Reliability of the middle form and short form were evidenced by coefficient alpha of 0.92 and 0.90 respectively. The long and middle forms were strongly correlated, r-value of 0.98 and the long and short forms were also highly correlated, r-value of 0.93. Consequently, long form, middle form and short form scales were evidenced very reliable and valid in measuring nuclear energy attitudes of various groups in general. They can be used for a variety of purpose of measuring and testing nuclear energy attitude.
