The purpose of this study was to identify university students' attitude to the foodservice attributes in their contribution to the selection or a fast food restaurant. Among 300 subjects, 214 were used in the analysis. The frequencies, Descriptives, ANOVA and t-test were used for the statistical analyses in this study. The findings from this study were as follows: firstly, there were no significant differences in the importance (or salience) of the foodservice attributes between the three different types of fast food restaurant. Secondly, there were no significant differences in the foodservice attributes between the means of the importance and salience for each of the selected fast food restaurants. Thirdly, there were no significant differences in the foodservice attributes in determining between the three types of fast food restaurant. Fourthly, there were no significant differences for the foodservice attributes between the mean importance (or salience) and universal mean for each of the selected fast food restaurants. Finally, the results of this study could provide some insight into the type of marketing strategies that may be successfully used by marketers who manage fast food restaurants.

Interpreting the phenomenon of Fast fashion that is prevalent these days, this research is meaningful in that it prepares the frame which suggests the vision to read the trend of 2000s and analyzes the property of phenomenon of Fast Fashion in the connection with society and culture. The so[io-cultural property can be largely characterized by consumption orientation, change orientation, efficiency, moment and multiculturism. Analyzing the phenomenon of fast fashion that emerged after 2000 on the basis of such sociocultural background, it is largely classified into imitation, fashionability, disposability, portability, transformation and convergence. Due to the hi-polarization of consumption, people tend to select imitated goods, and people accustomed to speed get interested in the fashionability of all Phenomena. Further, society that is transient and changing rapidly makes the habit of purchasing in disposability. The property of nomad society encourages to keep the habit of portability. Such change-oriented society and rapidly changing life pattern make them adapt in diverse transformation modes of Fast Fashion. Further, multi-cultural world integrates enterprises through combination of all cultures and the convergence of all factors.

This paper examines the use of semiotics for analyzing fashion advertisements in the fast fashion industry. While previous studies have explored the use of semiotics in various industries, the application of this theory in the fashion sector-especially regarding fast fashion's commercial videos related to sustainability-remains underexplored. The paper adopts Roland Barthes' Semiotics Theory to analyze the advertising videos related to the sustainability of major fast fashion brands such as H&M, MANGO, and ZARA. The research approach involved reviewing all commercial videos related to sustainability on these brands' official YouTube accounts and conducting comprehensive analyses of advertisements using the binary opposition analysis framework. The paper's findings indicate that these commercial videos serve as a platform to mold a brand's sustainability image and promote the notion that fast fashion brands are leading the charge toward sustainability, preparing for an unpredictable future, guiding people toward hope, and offering ultimate freedom. This research high-lights the necessity for a critical examination of advertising videos related to sustainability in the fast fashion industry to guarantee accountability and transparency.

The purpose of this study was to examine the impact of offering brand-name fast food at schools on student participation in school lunch. Two studies were conducted in Indiana, USA. In the first study, daily participation rate of 42 Indiana schools were compared between the days when brand-name fast food were offered and when they were not offered. The impact of brand-name fast food service on school lunch participation differed depending on the types of service offering brand-name fast food. Offering brand-name fast food solely as part of reimbursable meals or a-la-carte items was shown to induce students to the lunch option where brand-name fast food was offered. The second study examined the relationship of brand-name fast food service to monthly participation rate by analyzing secondary data of 1,282 Indiana schools using multiple regression analysis. Offering brand-name fast food was associated with monthly participation rate in school lunch only when schools offered them solely a-la-carte. Based on the results of two studies, it was concluded that offering brand-name fast food induced students from other lunch options to the options where brand-name fast food was offered on the day of service. However, increased or decreased participation in school lunch only on a few days could have not impacted average school lunch participation over a month. It is recommended that schools planning to offer brand-name fast food should make it available as part of reimbursable school lunches so that usual school lunch eaters would not be distracted to a-la-carte lines.

NJOY 코드 씨스템으로 JEF-1 평가 핵자료를 처리하여 고속로용 50군 군정수 SET을 생산하였다. 이를 이용하여 스물일곱가지 고속 임계로심 실험에서 얻어진 임계도 및 노심 중앙에서의 반응 율비를 계산하고 측정치와 비교·분석하였다. 아울러 ENDF/B-IV와-V 자료로 해석한 결과와도 비교·검토하였다. 일반적으로, 임계실험의 적분량 추정에서 JEF-1의 결과는 지금까지 사용해온 ENDF/B-IV의 결과보다 개선되었고, ENDF/B-V의 결과에 근접하고 있다.

Motion estimation plays an important role for video coding. In this paper, we derive optimal search patterns for fast block matching motion estimation. By analyzing the block matching algorithm as a function of block shape and size, we can find an optimal search pattern for initial motion estimation. The proposed idea, which has been verified experimentally by computer simulations, can provide an analytical basis for the current MPEG-2 proposals. In order to choose a more compact search pattern for BMA, we exploit the statistical relationship between the motion and the frame difference of each block.

간동맥화학색전술 중 사용되고 있는 Fast Low Dose C-arm CT의 평균선량을 DSA의 평균선량과 비교해 보고, 전체 누적선량에서 검사기법별 평균선량 분석을 통해 피폭선량을 분석해 보았다. 본원에서 환자 50명을 임의로 선정하여 Fast Low Dose C-arm CT와 DSA의 DAP 및 Air Kerma를 조사하여 비교하였으며, 4가지 검사기법(DSA, Fast Low Dose C-arm CT, Roadmap, Fluoroscopy)의 누적선량(DAP, Air Kerma)이 차지하는 비율을 분석하였다. 통계적인 비교 분석을 위해 통계프로그램 SPSS 20.0을 이용하여 대응표본 T검정, ANOVA 검증(post hoc test : Tukey)하였다. Fast Low Dose C-arm CT가 DSA에 비해 평균선량(DAP, Air Kerma)이 통계적으로 유의하게 낮았다.(p<.001) 간동맥화학색전술에서 항암제 주입 전후로 Fast Low Dose C-arm CT를 적극 활용하여 DSA의 검사 횟수를 줄인다면 환자의 의료방사선 피폭을 감소시킬 수 있다.

Zhang 등은 SAC'08에서 스트림 암호에 대한 향상된 고속 상관 공격을 제안하였다[8]. 이 공격은 Crypto'00에서 제안된 고속 상관 공격에 기반을 두고 FWT(fast Walsh transform)을 적용하여 설계되었다. [8]에서는 다양한 공격 환경에서 공격 알고리즘의 복잡도와 성공 확률이 제시되었지만, 제안된 공격 알고리즘을 실제 구현한 결과, 제시된 결과와 다르게 나타났다. 본 논문에서는 실험 결과를 토대로 [8]에서 제시된 공격 결과의 문제점을 분석하고, 이 공격 알고리즘이 유효하게 적용되는 bias의 threshold를 제시한다.

The engine behavior in a transient condition is important to not only emission regulations but also fuel economy. A fast response gas analyzer can be a useful tool to investigate exhaust gas in a transient operation. It should be designed to analyze gas concentration with a short time constant by a fast sampling module and an appropriate measuring method for each emission element. In this study, a new fast sampling module is introduced and flow analysis is performed by numerical simulation. The analysis has shown the proper operating condition and the sensitivity of the module for practical application. Calculated flow to the sampling module has $0.5{\sim}4%$ error, while backflow toward the expansion tube is expected when pressure in CP (Constant Pressure) chamber is over 0.6 bar. For a stable supply of flow to the optical cell, sample gas pressure should be in the range, $0.35{\sim}1.90$ bar, when the pressure in the CP camber and the optical cell are 0.2 bar and 0.158 bar, respectively.
